The SEC maintains a website (www.sec.gov) that contains reports, proxy and information statements, and other information regarding issuers, including Pioneer, that file electronically with the SEC.
The Company makes available free of charge through its website (www.pxd.com) its Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and, if applicable, amendments to those reports filed or furnished pursuant to Section 13(a) of the Exchange Act as soon as reasonably practicable after it electronically files such material with, or furnishes it to, the SEC. In addition to the reports filed or furnished with the SEC, Pioneer publicly discloses information from time to time in its press releases and investor presentations that are posted on its website or during publicly accessible investor conferences. Such information, including information posted on or connected to the Company's website, is not a part of, or incorporated by reference in, this Report or any other document the Company files with or furnishes to the SEC.
Mission and Strategies
The Company's mission is to be America's leading independent energy company, focused on value, safety, the environment, technology and its people. The Company's long-term strategy is centered around the following strategic objectives:
maintaining a strong balance sheet and financial flexibility;
returning free cash flow to shareholders via a stable and growing base dividend, a variable dividend and share repurchases;
utilizing the Company's scale and technological advancements to reduce costs and improve efficiency;
delivering economic production and reserve growth through drilling, completion and production improvement activities;
setting high expectations for employees and contractors to perform their jobs in a safe manner; and
maintaining industry-leading sustainable development and environmental stewardship efforts.
The Company's long-term strategy is anchored by the Company's interests in the long-lived Spraberry/Wolfcamp oil field located in the Midland Basin in West Texas, which has an estimated remaining productive life in excess of 50 years.
Competition
The oil and gas industry is highly competitive in the exploration for and acquisition of reserves, the acquisition of oil and gas leases, marketing of oil, NGL and gas production, the obtaining of equipment and services and the hiring and retention of staff necessary for the identification, evaluation, operation and acquisition and development of oil and gas properties. The Company's competitors include major integrated oil and gas companies, other independent oil and gas companies, and individuals engaged in the exploration for and development of oil and gas properties. The Company also faces competition from companies that supply alternative sources of energy, such as wind, solar power and other renewables. Competition will increase as alternative energy technology becomes more reliable and governments throughout the world support or mandate the use of such alternative energy.
Competitive advantage is gained in the oil and gas exploration and development industry by employing well-trained and experienced personnel who make prudent capital investment decisions based on management direction, embrace technological innovation and are focused on price and cost management. The Company has a team of dedicated employees who represent the

PIONEER NATURAL RESOURCES COMPANY
professional disciplines and sciences that the Company believes are necessary to allow Pioneer to maximize the long-term profitability and net asset value inherent in its physical assets.
See "Item 1A. Risk Factors - The Company faces significant competition and some of its competitors have resources in excess of the Company's available resources" for additional information.
Impact of the COVID-19 Pandemic
The COVID-19 pandemic resulted in a severe worldwide economic downturn, significantly disrupting the demand for oil throughout the world, and created significant volatility, uncertainty and turmoil in the oil and gas industry. The decrease in demand for oil, combined with pressures on the global supply-demand balance for oil and related products, resulted in oil prices declining significantly in late February 2020. Since mid-2020, oil prices have improved, with demand steadily increasing despite the uncertainties surrounding the COVID-19 variants, which have continued to inhibit a full global demand recovery. In addition, worldwide oil inventories are, from a historical perspective, very low and supply increases from OPEC, Russia and other oil producing nations are not expected to be sufficient to meet forecasted oil demand growth in 2022 and 2023, with many OPEC countries not able to produce at their OPEC agreed upon quota levels due to their lack of capital investments over the past few years in developing incremental oil supplies. Global oil price levels will ultimately depend on various factors and consequences beyond the Company's control, such as (i) the effectiveness of responses to combat the COVID-19 virus and their impact on domestic and worldwide demand, (ii) the ability of OPEC, Russia and other oil producing nations to manage the global oil supply, (iii) the timing and supply impact of any Iranian sanction relief on Iran's ability to export oil, (iv) additional actions by businesses and governments in response to the pandemic, (v) the global supply chain constraints associated with manufacturing delays, and (vi) political stability of oil consuming countries.
The Company continues to assess the impact of the COVID-19 pandemic on the Company and may modify its response as the impact of COVID-19 continues to evolve.
See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" for additional information.
Acquisition and Divestiture Activities
Acquisitions. The Company regularly seeks to acquire or trade acreage that complements its operations, provides exploration and development opportunities, increases the lateral length of future horizontal wells and provides superior returns on investment (including acquisitions of particular oil and gas assets or entities owning oil and gas assets and mergers, consolidations or other business combinations with such entities). The Company periodically evaluates and pursues acquisition and acreage trade opportunities and at any given time may be in various stages of evaluating such opportunities. Such stages may take the form of internal financial analyses, oil and gas reserve analyses, due diligence, the submission of indications of interest, preliminary negotiations, negotiations of letters of intent or negotiations of definitive agreements. The success of any acquisition or acreage trade is uncertain and depends on a number of factors, some of which are outside the Company's control.
On May 4, 2021, the Company completed the acquisition of Double Eagle III Midco 1 LLC ("DoublePoint") in exchange for 27 million shares of Pioneer common stock representing stock consideration transferred of $4.2 billion, $1 billion of cash and the assumption of $890 million of debt (the "DoublePoint Acquisition"). The DoublePoint Acquisition was accounted for as a business combination, with the fair value of the acquisition consideration allocated to the acquisition date fair value of assets acquired and liabilities assumed. The results of operations attributable to the assets acquired in the DoublePoint Acquisition were included in the Company's consolidated financial statements beginning in May 2021.
On January 12, 2021, the Company completed the acquisition of Parsley Energy, Inc., a Delaware corporation that previously traded on the NYSE under the symbol "PE" ("Parsley"), pursuant to the Agreement and Plan of Merger, dated as of October 20, 2020, among Pioneer, certain of its subsidiaries, Parsley and Parsley's subsidiary, Parsley Energy, LLC (the "Parsley Acquisition"). As part of the Parsley Acquisition, each eligible share of Parsley Class A common stock and each membership interest unit of Parsley Energy, LLC were automatically converted into the right to receive 0.1252 (the "Exchange Ratio") shares of Pioneer common stock. As a result, the Company issued 52 million shares of Pioneer common stock upon the consummation of the Parsley Acquisition, representing total stock consideration transferred of $6.9 billion. The Parsley Acquisition was accounted for as a business combination, with the fair value of the acquisition consideration allocated to the acquisition date fair value of assets acquired and liabilities assumed. The results of operations attributable to the assets acquired in the Parsley Acquisition were included in the Company's consolidated financial statements beginning on January 12, 2021.
See Note 3 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

PIONEER NATURAL RESOURCES COMPANY
Divestitures. The Company regularly reviews its asset base to identify nonstrategic assets, the disposition of which would increase capital resources available for other activities, create organizational and operational efficiencies and further the Company's objective of maintaining a strong balance sheet to ensure financial flexibility.
In December 2021, the Company completed the divestiture of all of its assets in the Delaware Basin (the "Delaware Divestiture") to Continental Resources, Inc. ("Continental") for cash proceeds of $3.1 billion, after normal closing adjustments. The sale of the Delaware Basin assets resulted in a pretax loss of $1.1 billion for the year ended December 31, 2021.
In October 2021, the Company completed the sale of approximately 20,000 net acres in western Glasscock County (the "Glasscock Divestiture") to Laredo Petroleum, Inc. ("Laredo") in exchange for $137 million in cash and 960 thousand shares of Laredo's common stock representing total consideration transferred of $206 million, after normal closing adjustments. The sale of these assets resulted in a pretax gain of $1 million for the year ended December 31, 2021.
In March 2021, the Company sold its well services business (the "Well Services Divestiture") to a third party for (i) net cash proceeds of $20 million and (ii) up to $4 million of additional cash proceeds to be earned over the next three years. The sale of these assets resulted in a pre-tax gain of $9 million for the year ended December 31, 2021.
See Note 3 and Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Marketing of Production
General. Production from the Company's properties is marketed using methods that are consistent with industry practices. Sales prices for oil, NGLs and gas production are negotiated based on factors normally considered in the industry, such as an index or spot price, distance from the well to a major pipeline, commodity quality and prevailing supply and demand conditions. See "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for additional information.
Seasonal nature of business. Generally, but not always, the demand for gas decreases during the summer months and increases during the winter months. Seasonal anomalies such as mild winters or hot summers may impact general seasonal changes in gas demand.
Delivery commitments. The Company has committed certain volumes of oil, NGL and gas to customers under a variety of contracts, some of which have volumetric firm transportation or fractionation requirements that could require monetary shortfall penalties if the Company's transported or fractionation volumes are insufficient to satisfy associated commitments. See Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Significant purchasers. During 2021, the Company's oil, NGL and gas sales to Sunoco Logistics Partners L.P., Shell Trading US Company and Occidental Energy Marketing Inc. accounted for 16 percent, 13 percent and 10 percent of the Company's oil, NGL and gas revenues, respectively. The loss of one of these significant purchasers or an inability to secure adequate pipeline, gas plant and NGL fractionation infrastructure for production could have a material adverse effect on the Company's ability to produce and sell its oil, NGL and gas production.
Revenues from sales of purchased oil and gas to Occidental Energy Marketing Inc. accounted for 27 percent of the Company's sales of purchased oil and gas. No other sales customer exceeded ten percent of the Company's sales of purchased oil and gas during 2021. The loss of the Company's significant purchaser of purchased oil and gas would not be expected to have a material adverse effect on the Company's ability to sell commodities it purchases from third parties.
See Note 13 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Sustainability and Environmental Compliance Costs
Since 2019, the Company has voluntarily published its Sustainability Report on an annual basis under the Global Reporting Initiative framework and the Sustainability Accounting Standards Board to address its ESG performance. For more information on the Company’s approach to sustainability management, refer to its Sustainability Report, which is available on its website (www.pxd.com).
The trend in environmental regulation has been to place more restrictions and limitations on activities that may affect the environment and thus, there can be no assurance as to the amount or timing of future expenditures for environmental compliance or remediation and actual future expenditures may be different from the amounts the Company currently anticipates. As with the upstream industry in general, complying with current and anticipated environmental laws and

8

PIONEER NATURAL RESOURCES COMPANY
regulations can increase the Company's capital costs to drill, complete, and construct and operate facilities. While these laws and regulations may affect the Company’s capital expenditures and net income, the Company does not believe they will have a material adverse effect on its business, financial position, results of operations or cash flows, nor does the Company believe that they will affect its competitive position since the operations of its competitors are generally similarly affected. Future events, such as changes in existing laws or enforcement policies, the promulgation of new laws or regulations or the development or discovery of new facts or conditions may cause the Company to incur significant costs. See "Health, Safety and Environmental Risks" in "Item 1A. Risk Factors" for additional information.
Human Capital
As of December 31, 2021, the Company had 1,932 employees, 857 of whom were employed in field operations and 32 of whom were employed in the water services business.
Values and governance. Pioneer's approach to human capital management is guided by its core RESPECT values. These values - Respect, Ethics and honesty, Safety and environment, Personal accountability, Entrepreneurship, Communication and Teamwork and inclusion - apply to all employees, suppliers and contractors, and guide how Pioneer interacts with all stakeholders. Pioneer aims to conduct all aspects of its business in accordance with these core values, which serve as the cultural foundation of the Company.
The Company's management committee and its board of directors set the Company's human capital management philosophies and goals. They routinely engage on workforce-related topics with the support of the human resources function, which oversees and administers the Company's human capital management programs.
The Company understands that employee recruiting, retention and development play a critical role in the Company's ability to conduct its business activities and achieve its long-term strategy. As a result, the Company's management committee and board of directors take a holistic view of human capital management and have established policies and development programs with the goal of creating an inclusive environment to allow all employees to feel respected, valued and connected to the business. The key aspects of the Company's human capital management include the Company's compensation and benefits program, diversity and inclusion initiatives, talent management and development, community involvement and Health, Safety and Environment ("HSE") programs.
Compensation and benefits program. The Company annually reviews its compensation levels for all employees in an effort to adjust compensation levels for changing market conditions, allowing the Company to attract and retain a highly skilled workforce. The Company considers its employees to be its greatest asset and encourages them to take full advantage of the benefits and programs the Company offers. To ensure Pioneer attracts and retains top talent, the Company maintains an above-average benefits package. Pioneer's employees participate in incentive plans that take into consideration individual and Company performance through a traditional cash bonus plan and a variable compensation plan denominated in Company stock. These plans align employee compensation with the Company's success on critical performance metrics and goals, while also recognizing individual performance. The variable compensation plan denominated in Company stock is designed to attract and retain employees, reward performance, and align the interest of employees with stockholders through the encouragement of stock ownership. In addition to cash and equity compensation, the Company also offers other employee benefits such as life and health (medical, dental & vision) insurance, paid time off, paid parental leave, flexible work schedules and a 401(k) plan that includes employer matching contributions.
The Company routinely benchmarks its compensation and benefits program to ensure that the programs remain competitive, continue to align with the Company's RESPECT values and meet the needs of employees and their families. As part of the Company's benefits program, it offers flexible work schedules, compressed workweeks and allowances for time off, including a parental leave policy that includes up to twelve weeks of paid leave for the primary caregiver and two weeks of paid leave for the secondary caregiver. The Company's wellness programs include on-site health centers, daycare centers, fitness centers, a range of healthy eating options at employee cafeterias and an employee assistance program to support the mental well-being of employees.
Diversity, equity and inclusion. The Company is committed to creating an inclusive environment where all employees feel respected, valued and connected to the business — a workplace to which individuals bring their authentic selves and can be successful in achieving their goals. The Company's dedicated Diversity, Equity and Inclusion ("DEI") program is focused on the following areas: community, culture and talent. The Company's management committee is accountable for having long-term DEI goals for their respective departments as the Company believes that senior leadership involvement is crucial for progress on these goals. In addition, DEI plans and progress are reviewed regularly with the board of directors. The Company has established a variety of DEI initiatives, such as OnePioneer, an employee-led Company organization whose goal is to advance DEI across the entire Company.

9

PIONEER NATURAL RESOURCES COMPANY
The Company actively monitors diversity metrics across its entire workforce. Currently, 29 percent of the board of directors and 36 percent of the management committee are women and 14 percent of the board of directors and 14 percent of the management committee identify as ethnic minorities. The Company intends to disclose its 2021 Consolidated EEO-1 Report on its website (www.pxd.com) after submission of the report to the U.S. Equal Employment Opportunity Commission in an effort to provide additional transparency into the Company's efforts to increase under-represented populations in its workforce.
Talent management and development. The Company's talent planning involves a comprehensive approach to adequately prepare employees for their responsibilities and for future advancement. The Company's performance management process occurs quarterly and, in accordance with the Company's RESPECT values, encourages and reinforces ongoing feedback and coaching between employees and managers, employee growth and development for their current role and future success and alignment of individual goals with company-wide goals and team objectives. Pioneer strives to build a more skilled and engaged workforce with skill-building and competency-based training and development opportunities. The Company's competency model comprises professional, leadership and technical competencies and complements each employee's individual development planning process. In furtherance of each employee's individual development plan, the Company's workforce is trained in accordance with Pioneer's 70/20/10 learning model (70 percent on-the-job and experience-based, 20 percent collaboration and coaching, 10 percent formal training). Employees are offered a variety of development options including in-person professional trainings, technical trainings, consultation services, vendor partnerships and more.
The Company's talent planning approach also identifies and targets development of critical talent. The Company identifies critical roles based on several factors, including strategic importance, scope and impact, and unique skills. Successor candidates for those critical roles are then identified as those who have the interest, ability and experience to succeed in the critical role within five years. Talent planning enables Pioneer to proactively advance succession planning and offer targeted development for high potential employees and successors, while enabling a cross-functional view of talent to increase visibility and mobility.
Community involvement. Pioneer's dedication to community well-being and success shows in the many ways the Company seeks to be a good neighbor in all of its operating areas. The Company's employees continually seek out events, organizations, initiatives and partnerships to support the communities where they work and live, and the Company is honored to support their ongoing efforts to enrich the communities where they live and work, including through a charitable matching program.
Health, safety and environment. The Company's HSE organization, with oversight from the Health, Safety and Environment Committee (the "HSE Committee") of the board of directors, provides tools to the Company's business teams to implement an organized approach for HSE activities to support and maintain a culture of improvement in safety and environmental practices. The Company's HSE policy covers all Pioneer operations and aligns with the Company's HSE Management System ("HSEMS"). It also requires contractors, vendors and suppliers to maintain an HSE policy that meets or exceeds the Company's policy. As outlined in the HSE policy, the Company is dedicated to protecting the health and safety of everyone who works at Pioneer facilities by encouraging high standards. All HSE incidents are required to be reported, no matter how small, and are investigated to develop corrective actions to reduce the likelihood of recurrence. The HSEMS consists of 13 elements that set HSE expectations, provide an avenue for employee engagement and drive HSE performance improvement. In support of driving continuous improvement, HSE milestones and criteria are established annually to drive safety and environmental performance. Throughout the year, progress toward these milestones and criteria are measured and reported to the management committee and the HSE Committee. Additionally, Pioneer has introduced a Serious Exposure program across all operations. While appropriate management of all HSE events is important, the Serious Exposure method prioritizes the highest-risk events, bringing increased visibility and proactive, consistent solutions to these more urgent situations.
During 2021, the Company continued to undertake significant effort to address the ongoing COVID-19 pandemic. At the onset of the pandemic, the Company implemented a cross-functional response team tasked with protecting employees and implementing policies and procedures to safely run the business. These priorities have been implemented through flexible policies and practices and frequent communications with employees and other key stakeholders. As the pandemic has progressed, the Company has continued to revise these policies and practices in light of guidance received from local, regional and federal authorities, where appropriate. During this time, the Company implemented a remote work environment for periods of time to ensure the safety of employees and implemented rigorous cleaning, disinfection and mitigation protocols to keep employees safe. The Company also encouraged the use of vaccines, providing incentives for employees who maintain their vaccination status.
Feedback and engagement. The Company's human capital management approach is augmented by a robust employee feedback program. The Company believes that giving employees a voice is paramount to creating a thriving and resilient culture and undertakes an annual engagement survey to provide a view into overall organizational health. The results are used

10

PIONEER NATURAL RESOURCES COMPANY
to identify issues that are important to employees and to implement improvement opportunities. In 2021, the Company received a 76 percent participation rate in the survey and its engagement score ranked in the top quartile of companies who used the same platform. Most importantly, the quantitative and qualitative survey data was utilized by leaders across the organization to identify strengths and opportunities for improvement and to inform action plans to address issues.

The oil and gas industry is extensively regulated at the federal, state, and local levels. Regulations affecting elements of the energy sector are under constant review for amendment or expansion and frequently more stringent requirements are imposed. Various federal and state agencies, including the Texas Railroad Commission, the Bureau of Land Management (the "BLM"), an agency of the U.S Department of the Interior ("DOI"), the U.S. Environmental Protection Agency (the "EPA") and the U.S. Occupational Safety and Health Administration ("OSHA"), have legal and regulatory authority and oversight over the Company's exploration and development activities and operations. Other agencies with certain authority over the Company's business include the Internal Revenue Service (the "IRS"), the SEC and NYSE. Ensuring compliance with the rules, regulations and orders promulgated by such entities requires extensive effort and incremental costs to comply, which affects the Company's profitability. Because public policy changes are commonplace, and existing laws and regulations are frequently amended, the Company is unable to predict the future cost or impact of compliance. However, the Company does not expect that any of these laws and regulations will affect its operations materially differently than they would affect other companies with similar operations, size and financial strength.
The following are significant areas of government control and regulation affecting the Company:
Securities regulations. Enterprises that sell securities in public markets are subject to regulatory oversight by agencies such as the SEC and the NYSE. This regulatory oversight imposes many requirements on the Company, including the responsibility for establishing and maintaining disclosure controls and procedures alongside internal controls over financial reporting, and ensuring that the financial statements and other information included in submissions to the SEC do not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made in such submissions not misleading. Failure to comply with the rules and regulations of the SEC could subject the Company to litigation from public or private plaintiffs. Failure to comply with the rules of the NYSE could result in the delisting of the Company's common stock, which would have an adverse effect on the market price and liquidity of the Company's common stock. Compliance with some of these rules and regulations is costly, and regulations are subject to change or reinterpretation.
Environmental and occupational health and safety matters. The Company strives to conduct its operations in a socially and environmentally responsible manner and is required to comply with many federal, state and local laws, regulations and executive orders concerning occupational safety and health, the discharge or other release of materials and protection of the environment and natural resources. These environmental legal requirements primarily relate to:
the discharge or other release of pollutants into federal and state waters and the ambient air;
assessing the environmental impact of seismic acquisition, drilling and construction activities;
the generation, storage, transportation and disposal of waste materials, including hazardous substances and wastes;
the emission of certain gases, including GHGs, into the atmosphere;
the monitoring, abandonment, reclamation and remediation of wells and other sites, including sites of former operations;
the development of emergency response and spill contingency plans;
the protection of threatened and endangered species; and
worker protection.
The more significant of these existing environmental and occupational health and safety laws and regulations include the following U.S. legal standards, as amended from time to time:
the Clean Air Act ("CAA"), which restricts the emission of air pollutants from many sources and imposes various preconstruction, operational, monitoring and reporting requirements, and has also been relied upon by the EPA as authority for adopting climate change regulatory initiatives relating to GHG emissions;
the Federal Water Pollution Control Act, also known as the Clean Water Act ("CWA"), which regulates discharges of pollutants from facilities to state and federal waters, and establishes the extent to which waterways are subject to federal jurisdiction and rulemaking as protected waters of the United States;
the Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), which imposes liability on generators, transporters, disposers and arrangers of hazardous substances at sites where hazardous substance releases have occurred or are threatening to occur;
the Resource Conservation and Recovery Act ("RCRA"), which governs the generation, treatment, storage, transport and disposal of solid wastes, including oil and gas exploration and production wastes and hazardous wastes;

11

PIONEER NATURAL RESOURCES COMPANY
the Safe Drinking Water Act ("SDWA"), which ensures the quality of the nation's public drinking water through adoption of drinking water standards and controlling the injection of waste fluids into below-ground formations that may adversely affect drinking water sources;
OSHA, which establishes workplace standards for the protection of the health and safety of employees, including the implementation of hazard communications programs designed to inform employees about hazardous substances in the workplace, potential harmful effects of these substances and appropriate control measures; and
the Endangered Species Act ("ESA"), which restricts activities that may affect federally identified endangered and threatened species or their habitats through the implementation of operating restrictions or a temporary, seasonal or permanent ban in affected areas.
Additionally, there are existing tribal, state and local jurisdictions where the Company operates that also have, or are developing or considering developing, similar environmental and occupational health and safety laws and regulations governing many of these same types of activities. Failure by the Company to comply with these laws, regulations and regulatory initiatives or controls may result in the assessment of sanctions, including administrative, civil and criminal penalties; the imposition of investigatory, remedial and corrective action obligations or the obligation to incur capital expenditures; the occurrence of restrictions, delays or cancellations in the permitting, development or expansion of projects; and issuance of injunctions restricting or prohibiting some or all of the Company's activities in a particular area. Historically, the Company's environmental and worker safety compliance costs have not had a material adverse effect on its results of operations. However, there can be no assurance that such costs will not be material in the future or that such future compliance will not have a material adverse effect on the Company's business and operational results.
The Company owns, leases or operates numerous properties that have been used for oil and gas exploration and production activities for many years. The Company also has acquired certain properties from third parties whose actions with respect to the management and disposal or release of hydrocarbons, hazardous substances or wastes at or from such properties were not under the Company's control prior to acquiring them. Under certain environmental laws and regulations, such as CERCLA and RCRA, the Company could incur strict joint and several liability due to damages to natural resources or for remediating hydrocarbons, hazardous substances or wastes disposed of or released by prior owners or operators. Moreover, an accidental release of materials into the environment during the Company's operations may cause it to incur significant costs and liabilities. The Company also could incur costs related to the clean-up of third-party sites to which it sent regulated substances for disposal or to which it sent equipment for cleaning and for damages to natural resources or other claims related to releases of regulated substances at or from such third-party sites.
Over time, the trend in environmental and occupational health and safety laws and regulations is to typically place more restrictions and limitations on activities that may adversely affect the environment or expose workers to injury. If existing legal requirements change or new legislative, regulatory or executive initiatives are developed and implemented in the future, the Company may be required to make significant, unanticipated capital and operating expenditures. The Company may not have insurance or be fully covered by insurance against all environmental and occupational health and safety risks. For more information on environmental and occupational health and safety matters, see the risk factors identified as Health, Safety and Environmental Risks in "Item 1A. Risk Factors."
Other regulation of the oil and gas industry. The Company's oil and gas operations are subject to laws and regulations that relate to matters including:
the acquisition of seismic data;
location, drilling and casing of wells;
hydraulic fracturing;
well production operations;
disposal of produced water;
regulation of transportation and sale of oil, NGLs and gas;
surface usage;
calculation and disbursement of royalty payments and production taxes;
restoration of properties used for oil and gas operations; and
transportation of production.
Development and production operations are subject to various regulations, including regulations requiring permits for the drilling of wells, the posting of bonds in connection with development and production activities and the filing of reports related to production operations. Texas, and some municipalities in which the Company operates, also regulate one or more of the following:
the location of wells;

12

PIONEER NATURAL RESOURCES COMPANY
the method of drilling and casing wells;
the method and ability to fracture stimulate wells;
the surface use and restoration of properties upon which wells are drilled;
the plugging and abandoning of wells; and
notices to surface owners and other third parties.
State laws regulate the size of drilling and spacing units or proration units governing the drilling and production of oil and gas properties. The Company relies on voluntary pooling, production sharing agreements and the drilling of allocation wells to develop its leases. In some instances, forced pooling or unitization may be implemented by third parties and may reduce the Company's interest in the unitized properties. In addition, state conservation laws establish maximum rates of production from oil and gas wells and generally prohibit the venting or flaring of gas without a permit. These laws and regulations may limit the amount of oil and gas the Company can produce from the Company's wells, negatively affect the economic decision to continue to produce these wells or limit the number of wells or locations that the Company can economically drill.
Approximately one percent of the Company's U.S. oil and gas leases are granted or approved by the federal government and administered by the BLM. All of the Company's federal leases are outside of Texas and the Company has no current plans to further develop the leases at this time. Such leases require compliance with detailed federal regulations and orders that regulate, among other matters, drilling and operations on lands covered by these leases and the calculation and disbursement of royalty payments to the federal government.

ITEM 1A.    RISK FACTORS
The Company's operations and financial results are subject to various risks and uncertainties, including but not limited to those described below. Other risks are described in "Item 1. Business — Competition, Markets and Regulations," "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk." The Company's business could also be affected by additional risks and uncertainties not currently known to the Company or that it currently deems to be immaterial. If any of these risks actually occur, it could materially harm the Company's business, financial condition or results of operations or impair the Company's ability to implement business plans or complete development activities as scheduled. In that case, the market price of the Company's common stock could decline. The following risk factors are summarized as general business and industry; operational; financial; health, safety and environmental; regulatory and risks associated with acquisitions.
General Business and Industry Risks
The COVID-19 pandemic and related developments in the global oil markets have had, and depending on the progression of the pandemic, may continue to have, material adverse consequences for general economic, business and industry conditions and for the Company's operations, financial condition, results of operations, cash flows and liquidity and those of its purchasers, suppliers and other counterparties.
Declining general economic, business or industry conditions could have a material adverse effect on the Company's results of operations.
The Company may be unable to make attractive acquisitions and any acquisition it completes is subject to substantial risks that could materially and adversely affect its business.
The Company's ability to complete dispositions of assets or sell partial interests in assets may be subject to factors beyond its control, and in certain cases the Company may be required to retain liabilities for certain matters.
The Company's operations and drilling activity are concentrated in the Midland Basin of West Texas; such concentration makes the Company vulnerable to risks associated with operating in a limited geographic area.
The Company may not be able to obtain access on commercially reasonable terms or otherwise to gathering systems, pipelines and other processing, fractionation, refining, storage, transportation and export facilities to market its oil, NGL and gas production.
The Company relies on a limited number of purchasers for a majority of its products.
The refining industry and export facilities may be unable to absorb U.S. oil production, and the ability to export oil is subject to suspension; in any such case, the resulting surplus could depress prices and restrict the availability of markets.
Estimates of proved reserves and future net cash flows are not precise. The actual quantities and net cash flows of the Company's proved reserves may prove to be lower than estimated.
Because the Company's producing wells decline continually over time, the Company will need to mitigate these declines through drilling and production enhancement initiatives and/or acquisitions.
A portion of the Company's total estimated proved reserves as of December 31, 2021 were undeveloped, and those proved reserves may not ultimately be developed.
The Company faces significant competition and some of its competitors have resources in excess of the Company's available resources.
The Company's business could be materially and adversely affected by security threats, including cybersecurity threats, and other disruptions.
Provisions of the Company's charter documents and Delaware law may inhibit a takeover, which could limit the price investors might be willing to pay in the future for the Company's common stock.
Operational Risks
The Company's operations involve many operational risks, some of which could result in unforeseen interruptions to the Company's operations and substantial losses to the Company for which the Company may not be adequately insured.
Exploration and development drilling involve substantial costs and risks and may not result in commercially productive reserves.
Part of the Company's strategy involves using some of the latest available horizontal drilling and completion techniques, which involve risks and uncertainties in their application.
The Company's expectations for future drilling activities will be realized over several years, making them susceptible to uncertainties that could materially alter the occurrence or timing of such activities.
Multi-well pad drilling may result in volatility in the Company's operating results.
The Company's operations are substantially dependent upon the availability of water and its ability to dispose of produced water gathered from drilling and production activities.
The Company's use of seismic data is subject to interpretation and may not accurately identify the presence of oil and gas, which could materially and adversely affect the results of its future drilling operations.

14

PIONEER NATURAL RESOURCES COMPANY
The Company's gas processing and gathering systems are subject to operational and regulatory risks.
Financial Risks
The prices of oil, NGLs and gas are highly volatile.
Future declines in the price of oil, NGLs and gas could result in a reduction in the carrying value of the Company's proved oil and gas properties.
The Company's actual production could differ materially from its forecasts.
The Company could experience periods of higher costs if commodity prices rise.
The Company is a party to debt instruments, a Credit Facility and other financial commitments that may limit the Company's ability to fund future business and financing activities.
• The Company's return of capital strategies, including its base and variable dividend policy and share repurchase program, may be changed at the discretion of the Company's board of directors, and the Company's ability to declare and pay base and variable dividends and repurchase shares are subject to certain considerations.
A failure by purchasers of the Company's production to satisfy their obligations to the Company could have a material adverse effect on the Company's results of operations.
The failure by counterparties to the Company's derivative risk management activities to perform their obligations could have a material adverse effect on the Company's results of operations.
The Company's derivative risk management activities could result in financial losses, limit the Company's potential gains or fail to protect the Company from declines in commodity prices.
Pioneer's ability to utilize its U.S. net operating loss carryforwards to offset future income taxes may be limited.
The Company periodically evaluates its unproved oil and gas properties to determine recoverability of its cost and could be required to recognize noncash charges in the earnings of future periods.
The Company periodically evaluates its goodwill for impairment and could be required to recognize noncash charges in the earnings of future periods.
Health, Safety and Environmental Risks
The Company's operations are subject to a series of risks arising out of the threat of climate change, energy conservation measures or initiatives that stimulate demand for alternative forms of energy.
The nature of the Company's assets and production operations may impact the environment or cause environmental contamination.
The Company's hydraulic fracturing and former sand mining operations may result in silica-related health issues and litigation.
Increasing attention to ESG matters may impact the Company's business.
Regulatory Risks
The Company's operations are subject to stringent environmental, oil and gas-related and occupational safety and health legal requirements.
Laws, regulations and other executive actions or regulatory initiatives regarding hydraulic fracturing could increase the Company's cost of doing business and result in additional operating restrictions, delays or cancellations that could have a material adverse effect on the Company's business, results of operations and financial condition.
Laws and regulations pertaining to protection of threatened and endangered species or to critical habitat, wetlands and natural resources could delay, restrict or prohibit the Company's operations and cause it to incur substantial costs.
The Company's transportation of gas; sales and purchases of oil, NGLs and gas or other energy commodities; and any derivative activities related to such energy commodities, expose the Company to potential regulatory risks.
The enactment of derivatives legislation could have a material adverse effect on the Company's ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks.
The Company's bylaws provide that the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the exclusive forum for certain legal actions between the Company and its stockholders and that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of causes of action arising under the Securities Act of 1933.
Risks Associated with Acquisitions
The financial and operational synergies attributable to acquisitions may vary from expectations.
Litigation relating to acquisitions could result in substantial costs to the Company.
The Company's future results will suffer if it does not effectively manage its expanded operations.

General Business and Industry Risks
The COVID-19 pandemic and related developments in the global oil markets have had, and depending on the progression of the pandemic, may continue to have, material adverse consequences for general economic, business and industry conditions and for the Company's operations, financial condition, results of operations, cash flows and liquidity and those of its purchasers, suppliers and other counterparties.
The onset of the COVID-19 pandemic significantly affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the onset of the pandemic resulted in widespread travel restrictions, business closures and other restrictions that led to a significant reduction in demand for oil, NGL and gas, resulting in oil prices declining significantly in the first quarter of 2020. While demand for and prices for oil, NGLs and gas have generally improved during 2021 as travel restrictions, business closures and other restrictions were lifted, an increase in infections or the onset of a new variant of the virus could again reduce demand for and prices of oil, NGLs and gas. If this were to continue for a prolonged period, the Company, similar to the steps it took at the onset of the pandemic in 2020, may have to make changes to its operations and capital budgets, and the Company's operations, financial condition, results of operations, cash flows and liquidity may be materially and adversely affected. Risks include, but are not limited to, the following:
An extended decline in commodity prices could materially and adversely affect the amount of oil, NGLs and gas that the Company can produce economically, which may result in (i) the Company having to make significant downward adjustments to its estimated proved reserves and (ii) a shortfall in expected cash flows, which could require the Company to reduce capital spending or borrow funds to cover any such shortfall. In addition, the continuation of depressed prices may adversely affect the ability of the Company to pay dividends or repurchase shares of common stock in the future.
A reduced demand for oil, combined with an oversupply of oil, would likely result in an oil surplus in the United States and worldwide. If the global demand for oil exports to foreign markets, or if the price that can be obtained in foreign markets does not support the transportation and other costs to reach those destinations, it may be uneconomical to invest in new wells and may cause the Company to shut in producing wells. The Company cannot be certain whether shut-in wells can successfully return to pre-shut-in production levels or that the costs required to return the wells to production will be economical.
The Company's ability to develop and sell its production could be materially and adversely affected by the inability or unwillingness of third parties to provide sufficient processing, fractionation, refining, transportation, storage or export facilities to the Company. For example, at the onset of the COVID-19 pandemic, oil storage in the United States was, at times, near full capacity in many locations. If this were to again occur for an extended period, the Company's purchasers might decline to purchase the Company's oil, NGLs and gas, and the Company may not be able to store its production. Such a lack of market for or storage capacity for the Company's products could require that the Company shut in some portion of its production. The amount of oil in storage may also keep oil prices at low levels for an extended period, even after demand begins to rise.
Under Texas law, the Texas Railroad Commission is empowered to prorate oil production in the state based on market demand. If the Texas Railroad Commission finds that waste is taking place or is reasonably imminent, it is empowered to adopt a rule or order to correct, prevent, or lessen the waste. If the Texas Railroad Commission imposes proration in the future, or if any other similar laws or regulations are imposed, those restrictions would limit the amount of oil, NGLs and gas the Company can produce.
It is possible that any delay, reduction or curtailment of the Company's development and producing operations, whether due to regulatory actions or actions by the Company in reaction to market conditions, could result in the loss of acreage through lease expiration.
Market conditions resulting from the effects of the COVID-19 pandemic, low oil prices, or a negative or recessionary economy could also increase the risk that the purchasers of the Company's production, lenders under its credit agreement, counterparties to its derivative instruments, and service providers may be unable to fulfill their obligations in a timely manner, or at all. If any such counterparty were to default on its obligations, such a default could have a material adverse effect on the Company's results of operations.
The Company performs assessments of its proved and unproved oil and gas properties whenever events or circumstances indicate that the carrying values of those assets may not be recoverable. To the extent such tests indicate a reduction of the estimated useful life or estimated future cash flows of the Company's proved oil and gas properties, an impairment charge could be required to reduce the carrying value of its proved oil and gas properties to their fair value. In addition, goodwill is assessed for impairment whenever it is likely that events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value.
The Company's operations may be adversely affected if significant portions of its workforce are unable to work effectively, including because of illness, quarantines, social distancing, government actions, or other restrictions in connection with the COVID-19 pandemic. The Company, as recommended by the Centers for Disease Control and

16

PIONEER NATURAL RESOURCES COMPANY
Prevention ("CDC"), has implemented workplace restrictions, including guidance for employees to work remotely for health and safety reasons, where possible. As some employees may have been or may in the future be placed in workplaces where exposure to COVID-19 is possible, the Company may be subject to risk of liability should such employees allege that the Company failed to adequately mitigate the risk of exposure to COVID-19, to the extent obligated to do so. In addition, in order to facilitate remote working arrangements, some employees are accessing workspaces from their personal devices through cloud-based systems, which could increase cybersecurity risks to the Company and to its employees. There can be no assurance that the Company's operations will not be curtailed or suspended or otherwise adversely affected due to such workforce issues.
The Company is not able to predict the ultimate long-term impact of the COVID-19 pandemic on the Company's business, which will depend on numerous evolving factors and future developments that are beyond the Company's control, including the length of time that the pandemic continues, the speed and effectiveness of responses to combat the COVID-19 virus, the impact of the pandemic and its aftermath on the demand for oil, NGLs and gas, the response of the overall economy and the financial markets as well as the effect of governmental actions taken in response to the COVID-19 pandemic.
Declining general economic, business or industry conditions could have a material adverse effect on the Company's results of operations.
The economies in the United States and certain countries in Europe and Asia have been growing, with resulting improvements in industrial demand and consumer confidence. However, other economies, such as those of certain South American nations, continue to face economic struggles or slowing economic growth. If these conditions worsen, combined with a decline in economic growth in other parts of the world, there could be a significant adverse effect on global financial markets and commodity prices. In addition, continued hostilities in the Middle East, and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect the global economy. Global or national health concerns, including the outbreak of pandemic or contagious disease, such as the COVID-19 pandemic, may adversely affect the Company by (i) reducing demand for its oil, NGL and gas because of reduced global or national economic activity, (ii) impairing its supply chain (for example, by limiting manufacturing of materials used in operations), and (iii) affecting the health of its workforce, rendering employees unable to work or travel. If the economic climate in the United States or abroad were to deteriorate, demand for petroleum products could diminish or stagnate, which could depress the prices at which the Company could sell its oil, NGLs and gas, affect the ability of the Company's vendors, suppliers and customers to continue operations and ultimately decrease the Company's cash flows and profitability. In addition, reduced worldwide demand for debt and equity securities issued by oil and gas companies may make it more difficult for the Company to raise capital to fund its operations or refinance its debt obligations.
The Company may be unable to make attractive acquisitions and any acquisition it completes is subject to substantial risks that could materially and adversely affect its business.
Acquisitions of oil and gas properties, including acreage trades, have from time to time contributed to the Company's growth. Acquisition opportunities in the oil and gas industry are very competitive, which can increase the cost of, or cause the Company to refrain from, completing acquisitions. The success of any acquisition will depend on a number of factors and involves potential risks, including, among other things:
the inability to accurately forecast future commodity prices and estimate the costs to develop the acquired reserves, the recoverable volumes of the acquired reserves, rates of future production and future net cash flows attainable from the acquired reserves;
the assumption of unknown liabilities, including environmental liabilities, and losses or costs for which the Company is not indemnified or for which the indemnity the Company receives is inadequate;
the validity of assumptions about costs, including synergies;
the effect on the Company's liquidity or financial leverage of using available cash or debt to finance acquisitions or from the amount of debt assumed as part of the acquisition;
the diversion of management's attention from other business concerns; and
an inability to hire, train or retain qualified personnel to manage and operate the Company's growing business and assets.
All of these factors affect whether an acquisition will ultimately generate cash flows sufficient to provide a suitable return on investment. Even though the Company performs a review of the properties it seeks to acquire that it believes is consistent with industry practices, such reviews are often limited in scope. As a result, among other risks, the Company's initial estimates of reserves may be subject to revision following an acquisition, which may materially and adversely affect the desired benefits of the acquisition. See "Risks Associated with Acquisitions" included in "Item 1A. Risk Factors" for additional information.

17

PIONEER NATURAL RESOURCES COMPANY
The Company's ability to complete dispositions of assets or sell partial interests in assets may be subject to factors beyond its control, and in certain cases the Company may be required to retain liabilities for certain matters.
The Company regularly reviews its property base for the purpose of identifying nonstrategic assets, the disposition of which would increase capital resources available for other activities and create organizational and operational efficiencies. In addition, from time to time, the Company sells an interest in its oil and gas properties for the purpose of assisting or accelerating the asset's development. Various factors could materially affect the ability of the Company to dispose of such nonstrategic assets or partial interests or complete announced dispositions, including the receipt of approvals of governmental agencies or third parties and the availability of purchasers willing to acquire the nonstrategic assets or partial interests on terms and at prices acceptable to the Company.
Sellers typically retain certain liabilities or indemnify buyers for certain pre-closing matters, such as matters of litigation, environmental contingencies, royalty obligations and income taxes. The magnitude of any such retained liability or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may be material. Also, as is typical in divestiture transactions, third parties may be unwilling to release the Company from guarantees or other credit support provided prior to the sale of the divested assets. As a result, after a divestiture, the Company may remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations.
The Company's operations and drilling activity are concentrated in the Midland Basin of West Texas, an area of high industry activity, which may affect its ability to obtain the personnel, equipment, services, resources and facilities access needed to complete its development activities as planned or result in increased costs; such concentration also makes the Company vulnerable to risks associated with operating in a limited geographic area.
The Company's producing properties are geographically concentrated in the Midland Basin of West Texas. Industry activity is high in the Midland Basin and demand for and costs of personnel, equipment, power, services and resources remains high. Any delay or inability to secure the personnel, equipment, power, services and resources could result in oil, NGL and gas production volumes being below the Company's forecasted volumes. In addition, any such negative effect on production volumes, or significant increases in costs, could have a material adverse effect on the Company's results of operations, cash flow and profitability.
As a result of this concentration, the Company may be disproportionately exposed to the impact of delays or interruptions of operations or production in this area caused by external factors such as governmental regulation, state politics, market limitations, produced water disposal limitations, water or sand shortages, or extreme weather related conditions.
The Company may not be able to obtain access on commercially reasonable terms or otherwise to gathering systems, pipelines and other processing, fractionation, refining, storage, transportation and export facilities to market its oil, NGL and gas production.
The marketing of oil, NGL and gas production depends in large part on the availability, proximity and capacity of gathering systems, pipelines and other processing, fractionation, refining, storage, transportation and export facilities, as well as the existence of adequate markets. If there were insufficient capacity available on these systems, if these systems were unavailable to the Company or if access to these systems were to become commercially unreasonable, the price offered for the Company's production could be significantly depressed, or the Company could be forced to shut in some production or delay or discontinue drilling plans and commercial production following a discovery of hydrocarbons while it constructs its own facility or awaits the availability of third party facilities. The Company also relies (and expects to rely in the future) on facilities developed and owned by third parties in order to gather, store, process, transport, fractionate, refine, export and sell its oil, NGL and gas production. The Company's plans to develop and sell production from its oil and gas reserves could be materially and adversely affected by the inability or unwillingness of third parties to provide sufficient gathering, transportation, storage, processing, fractionation, refining or export facilities to the Company, especially in areas of planned expansion where such facilities do not currently exist. Additionally, certain of these challenges may be compounded by a high level of industry activity in the Permian Basin.
For example, following Hurricane Harvey in 2017 and Hurricanes Gustav and Ike in 2008, certain Permian Basin gas processors were forced to shut down their plants due to the inability of certain Texas Gulf Coast NGL fractionators to operate. The Company was able to produce its oil wells and vent or flare the associated gas; however, there is no certainty the Company will vent or flare gas in the future as a result of its emissions reduction efforts and potential changes in regulations. The amount of oil and gas that can be produced is subject to limitations in certain circumstances, such as pipeline interruptions due to scheduled and unscheduled maintenance, excessive pressure, physical damage to gathering, transportation, storage, processing, fractionation, refining or export facilities, or lack of capacity at such facilities. The Company has periodically experienced high line pressure at its tank batteries, which has occasionally led to the flaring of gas due to the inability of the gas gathering systems in the areas to support the increased gas production. The curtailments arising from these and similar circumstances may

18

PIONEER NATURAL RESOURCES COMPANY
last for a few days, and in many cases, the Company may be provided only limited, if any, notice as to when these circumstances will arise and their duration.
To the extent that the Company enters into transportation contracts with pipelines that are subject to the United States Federal Energy Regulatory Commission ("FERC") regulation, the Company is subject to FERC requirements related to use of such capacity. Any failure on the Company's part to comply with FERC's regulations and policies related to pipeline transportation, reporting requirements or other regulations, and any failure to comply with a FERC-related pipeline's tariff, could result in the imposition of civil and criminal penalties. In addition, any changes in FERC or state regulations or requirements on pipeline transportation may result in increased transportation costs on pipelines that are subject to such regulation, thereby negatively impacting the Company's profitability.
The Company relies on a limited number of purchasers for a majority of its products.
A limited number of companies purchase a majority of the Company's oil, NGL and gas. The loss of a significant purchaser could have a material adverse effect on the Company's ability to sell its production.
The refining industry and export facilities may be unable to absorb U.S. oil production, and the ability to export oil is subject to suspension; in any such case, the resulting surplus could depress prices and restrict the availability of markets, which could materially and adversely affect the Company's results of operations.
Absent an expansion of U.S. refining and export capacity, an increase in U.S. production of oil could result in a surplus of these products in the U.S., which would likely cause prices for these commodities to fall and markets to constrict. Although U.S. law was changed in 2015 to permit the export of oil, exports may not occur if demand is lacking in foreign markets or the price that can be obtained in foreign markets does not support associated export capacity expansions, transportation and other costs. In such circumstances, the rate of return on the Company's capital projects would decline, possibly to levels that would make execution of the Company's drilling plans uneconomical, and a lack of market for the Company's products could require that the Company shut in some portion of its production. If this were to occur, the Company's production and cash flow could decrease, or could increase less than forecasted, which could have a material adverse effect on the Company's cash flow and profitability.
Under the 2015 federal law that lifted the ban on U.S. exports of oil, the President, in certain limited circumstances, has the authority to impose export licensing requirements or other restrictions on exports of oil from the U.S. for an initial period of up to one year, subject to extension. Such a limitation could result in a surplus of oil in the U.S., which would likely cause U.S. oil prices to fall.
Estimates of proved reserves and future net cash flows are not precise. The actual quantities and net cash flows of the Company's proved reserves may prove to be lower than estimated.
Numerous uncertainties exist in estimating quantities of proved reserves and future net cash flows therefrom. The estimates of proved reserves and related future net cash flows set forth in this Report are based on various assumptions, which may ultimately prove to be inaccurate.
Petroleum engineering is a subjective process of estimating underground accumulations of oil and gas that cannot be measured in an exact manner. Estimates of economically recoverable oil and gas reserves and estimates of future net cash flows depend upon a number of variable factors and assumptions, including the following:
historical production from the area compared with production from other producing areas;
the quality and quantity of available data;
the interpretation of that data;
the assumed effects of regulations by governmental agencies;
assumptions concerning future commodity prices; and
assumptions concerning future development costs, operating costs, severance, ad valorem and excise taxes, gathering, processing, transportation and fractionation costs and workover and remedial costs.
Because all proved reserve estimates are to some degree subjective, each of the following items may differ materially from those assumed in estimating proved reserves:
the quantities of oil and gas that are ultimately recovered;
the production costs incurred to recover the reserves;
the amount and timing of future development expenditures; and
future commodity prices.

19

PIONEER NATURAL RESOURCES COMPANY
Furthermore, different reserve engineers may make different estimates of proved reserves and cash flows based on the same available data. The Company's actual production, revenues and expenditures with respect to proved reserves will likely differ from the estimates, and the differences may be material.
As required by the SEC, the estimated discounted future net cash flows from proved reserves are based on average prices preceding the date of the estimate and costs as of the date of the estimate, while actual future prices and costs may be materially higher or lower. Actual future net cash flows also will be affected by factors such as:
the amount and timing of actual production;
the level of future capital spending;
increases or decreases in the supply of or demand for oil, NGL and gas; and
changes in governmental regulations or taxation.
Standardized Measure is a reporting convention that provides a common basis for comparing oil and gas companies subject to the rules and regulations of the SEC. In general, it requires the use of commodity prices that are based upon a historical 12-month unweighted average, as well as operating and development costs being incurred at the end of the reporting period. Consequently, it may not reflect the prices ordinarily received or that will be received for future oil and gas production because of seasonal price fluctuations or other varying market conditions, nor may it reflect the actual costs that will be required to produce or develop the oil and gas properties. Accordingly, estimates included herein of future net cash flows may be materially different from the future net cash flows that are ultimately received. In addition, the ten percent discount factor, which is required by the SEC to be used in calculating discounted future net cash flows for reporting purposes, may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with the Company or the oil and gas industry in general. Therefore, the estimates of discounted future net cash flows or Standardized Measure in this Report should not be construed as accurate estimates of the current market value of the Company's proved reserves.
Because the Company's producing wells decline continually over time, the Company will need to mitigate these declines through drilling and production enhancement initiatives and/or acquisitions.
Producing oil and gas reservoirs are characterized by declining production rates, which vary depending upon reservoir characteristics and other factors. Because the Company's producing wells decline continually over time as those wells are produced, the Company will need to mitigate these declines through drilling and production enhancement initiatives and/or acquisitions of additional recoverable reserves. There can be no assurance that the Company will be able to develop, exploit, find or acquire sufficient additional reserves to replace its current or future production.
A portion of the Company's total estimated proved reserves as of December 31, 2021 were undeveloped, and those proved reserves may not ultimately be developed.
As of December 31, 2021, 12 percent of the Company's total estimated proved reserves were undeveloped. Recovery of undeveloped proved reserves requires significant capital expenditures and successful drilling. The Company's reserve data assumes that the Company can and will make these expenditures and conduct these operations successfully, which assumptions may not prove to be correct. If the Company chooses not to spend the capital to develop these proved undeveloped reserves, or if the Company is not otherwise able to successfully develop these proved undeveloped reserves, the Company will be required to write-off these proved reserves. In addition, under the SEC's rules, because proved undeveloped reserves may be booked only if they relate to wells planned to be drilled within five years of the date of booking, the Company may be required to write-off any proved undeveloped reserves that are not developed within this five-year timeframe. The Company's future production levels and, therefore, its future cash flow and profitability will be impacted if it is not able to successfully develop its undeveloped leasehold acreage.
A substantial portion of the Company's acreage is currently held under leases that require it to establish and maintain production of hydrocarbons in paying quantities, and such leases are typically held by production from horizontal wells and/or older, lower-producing vertical wells. Unless production in paying quantities is maintained from existing lease-holding wells, or is established during the primary term of the lease and then maintained thereafter with respect to these leases, the leases will terminate, and the Company will lose the right to develop the undeveloped leasehold acreage.
The Company faces significant competition and some of its competitors have resources in excess of the Company's available resources.
The oil and gas industry is highly competitive. The Company competes with a large number of companies, producers and operators in a number of areas such as:
seeking to acquire oil and gas properties suitable for exploration or development;

20

PIONEER NATURAL RESOURCES COMPANY
marketing oil, NGL and gas production; and
seeking to acquire the equipment, services and expertise, including trained personnel, necessary to identify, evaluate, develop and operate its properties.
Some of the Company's competitors are larger and have substantially greater financial and other resources than the Company, and as such, the Company may be at a competitive disadvantage in the identification, acquisition and development of properties that complement the Company's operations. The Company also faces competition from companies that supply alternative sources of energy, such as wind, solar power or other renewable energy. Competition is expected to increase and in certain cases, governments are providing tax advantages and other subsidies to support alternative energy sources or are mandating the use of specific fuels or technologies. Governments and other parties are also promoting research into new technologies to accelerate the implementation of alternative energy sources.
The Company's business could be materially and adversely affected by security threats, including cybersecurity threats, and other disruptions.
As an oil and gas producer, the Company faces various security threats, including cybersecurity threats to gain unauthorized access to, or control of, sensitive information or to render data or systems corrupted or unusable; threats to the security of the Company's facilities and infrastructure or third party facilities and infrastructure, such as processing plants and pipelines; and threats from terrorist acts. The potential for such security threats has subjected the Company's operations to increased risks that could have a material adverse effect on the Company's business. In particular, the Company's implementation of various procedures and controls to monitor and mitigate security threats and to increase security for the Company's information, facilities and infrastructure may result in increased capital and operating costs. Costs for insurance have also increased as a result of security threats, and insurance coverage has become more difficult to obtain, and may not be available at prices acceptable to the Company or at all. Moreover, there can be no assurance that such procedures and controls will be sufficient to prevent security breaches from occurring. If any of these security breaches were to occur, they could lead to losses of sensitive information, critical infrastructure or capabilities essential to the Company's operations and could have a material adverse effect on the Company's reputation, financial position, results of operations and cash flows.
Cybersecurity attacks in particular are becoming more sophisticated. The Company relies extensively on information technology systems, including internet sites, computer software, data hosting facilities and other hardware and software platforms, some of which are hosted by third parties, to assist in conducting its business. The Company's technologies systems and networks, and those of its business associates may become the target of cybersecurity attacks, including without limitation denial-of-service attacks, malicious software, data privacy breaches by employees, insiders or others with authorized access, cyber or phishing-attacks, ransomware, attempts to gain unauthorized access to data and systems, and other electronic security breaches that could lead to disruptions in critical systems and materially and adversely affect the Company in a variety of ways, including the following:
unauthorized access to and release of seismic data, reserves information, strategic information or other sensitive or proprietary information, which could have a material adverse effect on the Company's ability to compete for oil and gas resources;
data corruption, communication interruption or other operational disruptions during drilling activities, which could result in the failure to reach the intended target or a drilling incident;
data corruption or operational disruptions of production infrastructure, which could result in loss of production or accidental discharges;
unauthorized access to and release of personal information of royalty owners, employees and vendors, or the data or confidential information of customers, suppliers or other third parties, which could expose the Company to allegations that it did not sufficiently protect that information;
a cybersecurity attack on a vendor or service provider, which could result in supply chain disruptions and could delay or halt operations;
a cybersecurity attack on third-party gathering, transportation, processing, fractionation, refining, storage or export facilities, which could delay or prevent the Company from transporting and marketing its production, resulting in a loss of revenues;
a cybersecurity attack involving commodities exchanges or financial institutions, which could slow or halt commodities trading, thus preventing the Company from marketing its production or engaging in derivative activities, resulting in a loss of revenues;
a cybersecurity attack on a communications network or power grid, which could cause operational disruptions resulting in the loss of revenues; and
a cybersecurity attack on the Company's automated and surveillance systems, which could cause a loss in production and potential environmental hazards.

21

PIONEER NATURAL RESOURCES COMPANY
These events could damage the Company's reputation and lead to financial losses from remedial actions, loss of business or potential liability. Additionally, certain cyber incidents, such as surveillance, may remain undetected for an extended period of time.
While the Company has experienced cybersecurity events in the past, including attempts to gain unauthorized access to data and systems, inadvertent data exposures, distributed denial-of-service attacks and phishing-attacks, the Company has not suffered any material losses as a result of such events. However, there is no assurance that the Company will not suffer such losses in the future. As cyber threats continue to evolve, the Company may be required to expend significant additional resources to continue to modify or enhance its protective measures or to investigate and remediate any information security vulnerabilities. Additionally, the continuing and evolving threat of cybersecurity attacks has resulted in evolving legal and compliance matters, including increased regulatory focus on prevention, which could require the Company to expend significant additional resources to meet such requirements.
Provisions of the Company's charter documents and Delaware law may inhibit a takeover, which could limit the price investors might be willing to pay in the future for the Company's common stock.
Provisions in the Company's certificate of incorporation and bylaws may have the effect of delaying or preventing an acquisition of the Company or a merger in which the Company is not the surviving company and may otherwise prevent or slow changes in the Company's board of directors and management. In addition, because the Company is incorporated in Delaware, it is governed by the provisions of Section 203 of the Delaware General Corporation Law. These provisions could discourage an acquisition of the Company or other change in control transactions and thereby negatively affect the price that investors might be willing to pay in the future for the Company's common stock.
Operational Risks
The Company's operations involve many operational risks, some of which could result in unforeseen interruptions to the Company's operations and substantial losses to the Company for which the Company may not be adequately insured.
The Company's operations, including drilling and completion activities and water distribution, collection and disposal activities, are subject to all the risks incident to the oil and gas development and production business, including:
blowouts, cratering, explosions and fires;
adverse weather effects;
environmental hazards, such as NGL and gas leaks, oil and produced water spills, pipeline and vessel ruptures, encountering naturally occurring radioactive materials ("NORM"), and unauthorized discharges of toxic chemicals, gases, brine, well stimulation and completion fluids or other pollutants onto the surface or into the subsurface environment;
high costs, shortages or delivery delays of equipment, labor or other services or materials, such as water and sand for hydraulic fracturing;
facility or equipment malfunctions, failures or accidents;
title problems;
pipe or cement failures or casing collapses;
uncontrollable flows of oil, gas or water;
compliance with environmental and other governmental requirements, including executive actions and regulatory or legislative efforts under a Biden administration;
lost or damaged oilfield workover and service tools;
surface access restrictions;
unusual or unexpected geological formations or pressure or irregularities in formations;
terrorism, vandalism, extreme physical acts of activism against fossil fuel interests and physical, electronic and cybersecurity breaches and global or national health concerns, including the outbreak of a pandemic or contagious disease, such as the recent COVID-19 pandemic; and
natural disasters.
The Company's overall exposure to operational risks may increase as its drilling activity expands, along with any associated increases in internally-provided well services, water distribution, water collection, disposal or other services. In addition, any of these risks could adversely impact the Company's service providers and suppliers, causing its supply chain to be interrupted, slowed or rendered inoperable. Any of these risks could result in substantial losses to the Company due to injury or loss of life, damage to or destruction of wells, production facilities or other property and natural resources, clean-up responsibilities, regulatory investigations and penalties and suspension of operations.

22

PIONEER NATURAL RESOURCES COMPANY
The Company may not be insured or is not fully insured against certain of the risks described above, either because such insurance is not available or because of the high premium costs and deductibles associated with obtaining such insurance. Additionally, the Company relies, to a large extent, on facilities owned and operated by third-parties, and damage to or destruction of those third-party facilities could adversely affect the ability of the Company to produce, gather, process, fractionate, refine, store, transport, export and sell its hydrocarbons.
Exploration and development drilling involve substantial costs and risks and may not result in commercially productive reserves.
Drilling involves numerous risks, including the risk that no commercially productive oil or gas reservoirs will be encountered. The cost of drilling, completing and operating wells is often uncertain and drilling operations may be curtailed, delayed or canceled, or become costlier, as a result of a variety of factors, including:
unexpected drilling conditions;
unexpected pressure or irregularities in formations;
equipment failures or accidents;
construction delays;
fracture stimulation accidents or failures;
adverse weather conditions;
restricted access to land for drilling or laying pipelines;
title defects;
lack of available gathering, transportation, processing, fractionation, storage, refining or export facilities;
lack of available capacity on interconnecting transmission pipelines;
access to, and the cost and availability of, the equipment, services, resources and personnel required to complete the Company's drilling, completion and operating activities; and
restrictions, delays or cancellations imposed by or resulting from compliance with or changes in environmental and other governmental, regulatory or contractual requirements.
The Company's future drilling activities may not be successful and, if unsuccessful, the Company's proved reserves and production would decline, which could have an adverse effect on the Company's future results of operations and financial condition. While all drilling, whether developmental, extension or exploratory, involves these risks, exploratory and extension drilling involves greater risks of dry holes or failure to find commercial quantities of hydrocarbons. The Company expects that it will continue to recognize exploration and abandonments expense in 2022.
Part of the Company's strategy involves using some of the latest available horizontal drilling and completion techniques, which involve risks and uncertainties in their application.
The Company's operations involve utilizing some of the latest drilling and completion techniques as developed by it and its service providers. Risks that the Company faces while drilling horizontal wells include, but are not limited to, the following:
landing the wellbore in the desired drilling zone;
staying in the desired drilling zone while drilling horizontally through the formation;
running casing the entire length of the wellbore; and
being able to run tools and other equipment consistently through the horizontal wellbore.
Risks that the Company faces while completing wells include, but are not limited to, the following:
the ability to fracture stimulate the planned number of stages;
the ability to run tools the entire length of the wellbore during completion operations; and
the ability to successfully clean out the wellbore after completion of the final fracture stimulation stage.
Drilling in emerging areas is more uncertain than drilling in areas that are more developed and have a longer history of established drilling operations. New discoveries and emerging formations have limited or no production history and, consequently, the Company is more limited in assessing future drilling results in these areas. If the Company's drilling results are worse than anticipated, the return on investment for a particular project may not be as attractive as anticipated and the Company may recognize noncash charges to reduce the carrying value of its unproved properties in those areas.
The Company's expectations for future drilling activities will be realized over several years, making them susceptible to uncertainties that could materially alter the occurrence or timing of such activities.
The Company has identified drilling locations and prospects for future drilling opportunities, including development, exploratory, extension and infill drilling activities. These drilling locations and prospects represent a significant part of the

23

PIONEER NATURAL RESOURCES COMPANY
Company's future drilling plans. For example, the Company's proved reserves as of December 31, 2021 include proved undeveloped reserves and proved developed non-producing reserves of 130 MMBbls of oil, 92 MMBbls of NGL and 462 Bcf of gas. The Company's ability to drill and develop these locations depends on a number of factors, including the availability and cost of capital, regulatory approvals, negotiation of agreements with third parties, commodity prices, costs, access to and availability of equipment, services, resources and personnel, and drilling results. There can be no assurance that the Company will drill these locations or that the Company will be able to produce oil or gas reserves from these locations or any other potential drilling locations. Well results vary by formation and geographic area, and the Company generally prioritizes its drilling activities to focus on remaining locations that are believed to offer the highest return. Changes in the laws or regulations on which the Company relies in planning and executing its drilling programs could materially and adversely impact the Company's ability to successfully complete those programs. For example, under current Texas laws and regulations, the Company may receive permits to drill, and may drill and complete, certain horizontal wells that traverse one or more units and/or leases; a change in those laws or regulations could materially and adversely impact the Company's ability to drill those wells. Because of these uncertainties, the Company cannot give any assurance as to the timing of these activities or that they will ultimately result in the realization of proved reserves or meet the Company's expectations for success. As such, the Company's actual drilling activities may materially differ from the Company's current expectations, which could have a material adverse effect on the Company's proved reserves, financial condition and results of operations.
Multi-well pad drilling may result in volatility in the Company's operating results.
The Company utilizes multi-well pad drilling, and wells drilled on a pad are not placed on production until all wells on the pad are drilled and completed. In addition, problems affecting a single well could adversely affect production from all of the wells on the pad. As a result, multi-well pad drilling can cause delays in the scheduled commencement of production, or interruptions in ongoing production. These delays or interruptions may cause volatility in the Company's operating results. Further, any delay, reduction or curtailment of the Company's development and producing operations due to operational delays caused by multi-well pad drilling could result in the loss of acreage through lease expiration.
The Company's operations are substantially dependent upon the availability of water and its ability to dispose of produced water gathered from drilling and production activities. Restrictions on the Company's ability to obtain water or dispose of produced water may have a material adverse effect on its financial condition, results of operations and cash flows.
Water is an essential component of the Company's drilling and hydraulic fracturing processes. Limitations or restrictions on the Company's ability to secure sufficient amounts of water (including limitations resulting from natural causes such as drought), could materially and adversely impact its operations. Severe drought conditions can result in local water districts taking steps to restrict the use of water in their jurisdiction for drilling and hydraulic fracturing in order to protect the local water supply. If the Company is unable to obtain water to use in its operations from local sources, it may need to be obtained from new sources and transported to drilling sites, resulting in increased costs, which could have a material adverse effect on its financial condition, results of operations and cash flows.
In addition, the Company must dispose of the fluids produced from oil and gas production operations, including produced water, which it does directly or through the use of third party vendors. The legal requirements related to the disposal of produced water into a non-producing geologic formation by means of underground injection wells are subject to change based on concerns of the public or governmental authorities regarding such disposal activities. One such concern arises from seismic events near underground disposal wells that are used for the disposal of produced water resulting from oil and gas activities. In 2016, the United States Geological Survey identified Texas as being among the states with areas of increased rates of induced seismicity that could be attributed to fluid injection or oil and gas extraction. Additionally, regulators in some states have imposed, or are considering imposing, additional requirements in the permitting of produced water disposal wells to assess any relationship between seismicity and the use of such wells. For example, in Texas, the Texas Railroad Commission has adopted rules governing the permitting or re-permitting of wells used to dispose of produced water and other fluids resulting from the production of oil and gas in order to address these seismic activity concerns within the state. Among other things, these rules require companies seeking permits for disposal wells to provide seismic activity data in permit applications, provide for more frequent monitoring and reporting for certain wells and allow the state to modify, suspend or terminate permits on grounds that a disposal well is likely to be, or determined to be, causing seismic activity.
In response to recent seismic activity in the Midland Basin over the past couple of years, the Texas Railroad Commission has pursued a series of actions commencing in the latter half of 2021, including suspending deep disposal activity and curtailing certain shallow disposal activities in the areas of heightened seismic activity. Such restrictions have not had a material impact on the Company's operations to date, but further restrictions across the basin as a result of more stringent regulations or legal directives, potential litigation or other developments could materially impact its ability to dispose of produced water, which could have a material adverse effect on the Company's business, financial condition and results of operations.

24

PIONEER NATURAL RESOURCES COMPANY
The Company's use of seismic data is subject to interpretation and may not accurately identify the presence of oil and gas, which could materially and adversely affect the results of its future drilling operations.
Even when properly used and interpreted, seismic data and visualization techniques are only tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. As a result, the Company's drilling activities may not be successful or economic. In addition, the use of advanced technologies, such as 3-D seismic data, requires greater pre-drilling expenditures than traditional drilling strategies, and the Company could incur losses as a result of such expenditures.
The Company's gas processing and gathering systems are subject to operational and regulatory risks, which could result in significant damages and the loss of revenue.
As of December 31, 2021, the Company owns interests in 11 gas processing plants, including the related gathering systems. There are significant risks associated with the operation of gas processing plants and the associated gathering systems. Gas and NGLs are volatile and explosive and may include carcinogens. Damage to or improper operation of gas processing plants or gathering systems could result in an explosion or the discharge of toxic gases, which could result in significant damage claims in addition to interrupting a revenue source.
Moreover, while the Company's gas processing and gathering systems generally are not currently subject to FERC or state regulation with respect to rates or terms and conditions of service, there can be no assurance that such processing and gathering operations will continue to be unregulated in the future. Although these facilities may not be directly regulated, other laws and regulations may affect the availability of gas for gathering and processing, such as state regulations regarding production rates and the maximum daily production allowable from gas wells, which could impact the Company's business in these areas. Such regulation could result in additional costs and reduced revenues.
Financial Risks
The prices of oil, NGLs and gas are highly volatile. A sustained decline in these commodity prices could materially and adversely affect the Company's business, financial condition and results of operations.
The Company's revenues, profitability, cash flow and future rate of growth are highly dependent on commodity prices. Commodity prices may fluctuate widely in response to relatively minor changes in the supply of and demand for oil, NGL and gas, market uncertainty and a variety of additional factors that are beyond the Company's control, such as:
domestic and worldwide supply of and demand for oil, NGL and gas;
worldwide oil, NGL and gas inventory levels, including at Cushing, Oklahoma, the benchmark location for WTI oil prices, and the U.S. Gulf Coast, where the majority of the U.S. refinery capacity exists;
volatility and trading patterns in the commodity-futures markets;
the capacity of U.S. and international refiners to utilize U.S. supplies of oil and condensate;
weather conditions;
overall domestic and global political and economic conditions, including the imposition of tariffs or trade or other economic sanctions, political instability or armed conflict in oil and gas producing regions;
global or national health concerns, including the outbreak of pandemic or contagious disease, such as the recent COVID-19 virus, which may reduce the demand for oil, NGL and gas because of reduced global or national economic activity;
actions of OPEC, its members and other state-controlled oil companies relating to oil price and production controls;
the price and quantity of oil, NGL and LNG imports to and exports from the U.S.;
technological advances or social attitudes or policies affecting energy consumption and energy supply;
domestic and foreign governmental legislative efforts, executive actions and regulations, including environmental regulations, climate change regulations and taxation;
the effect of energy conservation efforts;
stockholder activism or activities by non-governmental organizations to limit certain sources of capital for the energy sector or restrict the exploration, development and production of oil and gas;
the proximity, capacity, cost and availability of gathering systems, pipelines and other processing, fractionation, refinery, storage and export facilities; and
the price, availability and acceptance of alternative fuels.
Commodity prices have historically been, and continue to be, extremely volatile. For example, the Brent oil prices in 2021 ranged from a high of $86.40 to a low of $51.09 per Bbl and the NYMEX gas prices in 2021 ranged from a high of $6.31 to a low of $2.45 per MMBtu. The Company expects this volatility to continue. A further or extended decline in commodity prices could materially and adversely affect the Company's future business, financial condition, results of operations, liquidity

25

PIONEER NATURAL RESOURCES COMPANY
or its ability to fund planned capital expenditures, pay dividends or repurchase shares of common stock. The Company makes price assumptions that are used for planning purposes, and a significant portion of the Company's cash outlays, including rent, salaries and noncancellable capital and transportation commitments, are largely fixed in nature. Accordingly, if commodity prices are below the expectations on which these commitments were based, the Company's financial results are likely to be adversely and disproportionately affected because these cash outlays are not variable in the short-term and cannot be quickly reduced to respond to unanticipated decreases in commodity prices.
Significant or extended price declines could also materially and adversely affect the amount of oil, NGL and gas that the Company can produce economically, which may result in the Company having to make significant downward adjustments to its estimated proved reserves. A reduction in production could also result in a shortfall in expected cash flows and require the Company to reduce capital spending or borrow funds to cover any such shortfall. Any of these factors could negatively affect the Company's ability to replace its production and its future rate of growth.
Future declines in the price of oil, NGLs and gas could result in a reduction in the carrying value of the Company's proved oil and gas properties, which could materially and adversely affect the Company's results of operations.
Significant or extended price declines could result in the Company having to make downward adjustments to the carrying value of its proved oil and gas properties. The Company performs assessments of the recoverability of its oil and gas properties whenever events or circumstances indicate that the carrying values of those assets may not be recoverable. In order to perform these assessments, management uses various observable and unobservable inputs, including management's outlooks for (i) proved reserves and risk-adjusted probable and possible reserves, (ii) commodity prices, (iii) production costs, (iv) capital expenditures and (v) production. To the extent such tests indicate a reduction of the estimated useful life or estimated future cash flows of the Company's oil and gas properties, the carrying value may not be recoverable and therefore an impairment charge would be required to reduce the carrying value of the proved properties to their fair value. The Company may incur impairment charges in the future, which could materially affect the Company's results of operations in the period incurred. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Results of Operations - Impairment of oil and gas properties and other long-lived assets" and Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
The Company's actual production could differ materially from its forecasts.
From time to time, the Company provides forecasts of expected quantities of future oil and gas production and other financial and operating results. These forecasts are based on a number of estimates and assumptions, including that none of the risks associated with the Company's oil and gas operations summarized in this "Item 1A. Risk Factors" occur. Production forecasts, specifically, are based on assumptions such as:
expectations of production from existing wells and future drilling activity;
the absence of facility or equipment malfunctions;
the absence of adverse weather effects;
expectations of commodity prices, which could experience significant volatility;
expected well costs; and
the assumed effects of regulation by governmental agencies, which could make certain drilling activities or production uneconomical.
Should any of these assumptions prove inaccurate, or should the Company's development plans change, actual production could be materially and adversely affected.
The Company could experience periods of higher costs if commodity prices rise. These increases could reduce the Company's profitability, cash flow and ability to complete development activities as planned.
Historically, the Company's capital and operating costs have risen during periods of increasing oil, NGL and gas prices. These cost increases result from a variety of factors beyond the Company's control, such as increases in the cost of electricity, steel and other raw materials that the Company and its vendors rely upon; increased demand for labor, services and materials as drilling activity increases; and increased production and ad valorem taxes. Costs may rise faster than increases in the Company's revenue if commodity prices rise, thereby negatively impacting the Company's profitability, cash flow and ability to complete development activities as scheduled and on budget. This impact may be magnified to the extent that the Company's ability to participate in the commodity price increases is limited by its derivative risk management activities.

26

PIONEER NATURAL RESOURCES COMPANY
The Company is a party to debt instruments, a Credit Facility and other financial commitments that may limit the Company's ability to fund future business and financing activities.
The Company is a borrower under fixed rate senior and convertible notes and maintains a Credit Facility that was undrawn as of December 31, 2021. The terms of the Company's borrowings specify scheduled debt repayments and require the Company to comply with certain associated covenants and restrictions. The Company's ability to comply with the debt repayment terms, associated covenants and restrictions is dependent on, among other things, factors outside the Company's direct control, such as commodity prices and interest rates. In addition, from time to time, the Company enters into arrangements and transactions that can give rise to material off-balance sheet obligations, including firm purchase, transportation and fractionation commitments, gathering, processing, transportation and storage commitments on uncertain volumes of future throughput, commitments to purchase minimum volumes of goods and services, operating lease agreements and drilling commitments. The Company's financial commitments could have important consequences to its business including, but not limited to, the following:
the incurrence of charges associated with unused commitments if actual activities do not meet the Company's expectations at the time such commitments are entered into;
increasing its vulnerability to adverse economic and industry conditions;
limiting its flexibility to plan for, or react to, changes in its business and industry;
limiting its ability to fund future development activities or engage in future acquisitions; and
placing it at a competitive disadvantage compared to competitors that have less debt and/or fewer financial commitments.
The Company's ability to obtain additional financing is also affected by the Company's debt credit ratings and competition for available debt financing. A ratings downgrade could materially and adversely impact the Company's ability to access debt markets, increase the borrowing cost under the Company's Credit Facility and the cost of future debt and potentially require the Company to post letters of credit or other forms of credit support for certain obligations.
The Company's return of capital strategies, including its base and variable dividend policy and share repurchase program, may be changed at the discretion of the Company's board of directors, and the Company's ability to declare and pay base and variable dividends and repurchase shares are subject to certain considerations.
Dividends, whether base or variable, are authorized and determined by the Company's board of directors at its sole discretion. The Company's stock repurchase program has no time limit, may be modified, suspended or terminated at any time by the board of directors, and the repurchase of shares pursuant to the stock repurchase program approved by the board of directors are made from time to time based on management's discretion. Decisions regarding the payment of dividends and the repurchase of shares are subject to a number of considerations, including:
cash available for distribution or repurchases;
the Company's results of operations and anticipated future results of operations;
the Company's financial condition, especially in relation to its anticipated future capital needs;
the level of cash reserves the Company maintains to fund future capital expenditures;
the Company's stock price; and
other factors the board of directors deems relevant.
The frequency and amount of dividends, if any, may vary significantly from amounts paid in previous periods. The Company can provide no assurance that it will continue to pay base or variable dividends or authorize share repurchases at the current rate or at all. Any elimination of or downward revision in the Company's base or variable dividend payout or stock repurchase program could adversely affect the total return of an investment in and have a material adverse effect on the market price, of the Company's common stock.
A failure by purchasers of the Company's production to satisfy their obligations to the Company could have a material adverse effect on the Company's results of operation.
The Company relies on a limited number of purchasers to purchase a majority of its products. To the extent that purchasers of the Company's production rely on access to the credit or equity markets to fund their operations, there is a risk that those purchasers could default in their contractual obligations to the Company if such purchasers were unable to access the credit or equity markets for an extended period of time. If for any reason the Company were to determine that it was probable that some or all of the accounts receivable from any one or more of the purchasers of the Company's production were uncollectible, the Company would recognize a charge in the earnings of that period for the probable loss.

The failure by counterparties to the Company's derivative risk management activities to perform their obligations could have a material adverse effect on the Company's results of operations.
The use of derivative risk management transactions involves the risk that the counterparties will be unable to meet the financial terms of such transactions. The Company is unable to predict changes in a counterparty's creditworthiness or ability to perform. Even if the Company accurately predicts sudden changes, the Company's ability to negate the risk may be limited depending upon market conditions and the contractual terms of the transactions. During periods of declining commodity prices, the Company's derivative receivable positions generally increase, which increases the Company's counterparty credit exposure. In periods of lower commodity prices, if any of the Company's counterparties were to default on its obligations under the Company's derivative arrangements, such a default could (i) have a material adverse effect on the Company's results of operations, (ii) result in a larger percentage of the Company's future production being subject to commodity price changes and (iii) increase the likelihood that the Company's derivative arrangements may not achieve their intended strategic purposes.
The Company's derivative risk management activities could result in financial losses, limit the Company's potential gains or fail to protect the Company from declines in commodity prices; the Company may not enter into derivative arrangements with respect to future volumes if prices are unattractive.
The Company has historically entered into derivative arrangements covering a portion of its oil, NGL and gas production to mitigate the effect of commodity price volatility on the Company's net cash provided by operating activities and its net asset value, support the Company's annual capital expenditure plans and planned dividend payments. In addition, Pioneer assumed existing derivative arrangements in the Parsley Acquisition and DoublePoint Acquisition, which are now part of the Company's consolidated derivative arrangements. These derivative arrangements, on a combined basis, are subject to mark-to-market accounting treatment, and the changes in fair market value of the contracts are reported in the Company's statements of operations each quarter, which may result in significant noncash gains or losses.
While intended to reduce the effects of oil, NGL and gas price volatility, the Company's derivative arrangements may limit the Company's potential gains if prices rise over the price established by such arrangements. Conversely, the Company's derivative arrangements may be inadequate to protect the Company from continuing and prolonged declines in the price of oil, NGL or gas. Global commodity prices are volatile. Such volatility challenges the Company's ability to forecast the price of oil, NGL and gas, and, as a result, it may become more difficult for the Company to manage its derivative arrangements. In trying to manage its exposure to commodity price risk, the Company may end up with too many or too few derivatives, depending upon where commodity prices settle relative to the Company's derivative price thresholds and how the Company's oil, NGL and gas volumes and production mix fluctuate relative to expectations when the derivatives were entered.
The Company's derivative arrangements may also expose the Company to risk of financial loss in certain circumstances, including, but not limited to, when:
production is less than the contracted derivative volumes;
the counterparty to the derivative contract defaults on its contract obligations;
there is a change in the expected differential between the underlying price in the derivative contract and actual prices received; or
a sudden, unexpected event materially impacts oil and gas prices.
Failure to protect against declines in commodity prices exposes the Company to reduced liquidity when prices decline. A sustained lower commodity price environment would result in lower realized prices for unprotected volumes and reduce the prices at which the Company could enter into derivative contracts on future volumes. The Company has significantly reduced its derivative arrangements for 2022 and beyond; therefore, any decreases in commodity prices for oil, NGLs and gas could have a material adverse effect on the Company's financial condition, cash flow, liquidity and results of operations.
Pioneer's ability to utilize its U.S. net operating loss carryforwards to offset future income taxes may be limited.
As of December 31, 2021, Pioneer had U.S. federal net operating loss carryforwards ("NOLs") of $6.0 billion. Of the total NOLs, $2.2 billion were incurred prior to January 1, 2018 and will begin to expire, if unused, in 2032, and $3.8 billion were incurred on or after January 1, 2018 and will not expire and will be carried forward indefinitely under current tax law. Pioneer's ability to utilize these NOLs and other tax attributes to reduce future taxable income depends on many factors, including its future income, which cannot be assured. Section 382 of the Code ("Section 382") generally imposes an annual limitation on the amount of NOLs that may be used to offset taxable income when a corporation has undergone an "ownership change" (as determined under Section 382). An ownership change generally occurs if one or more stockholders (or groups of stockholders) who are each deemed to own at least five percent of such corporation's stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. In the event that an ownership change occurs, utilization of the relevant corporation's NOLs would be subject to an annual limitation under Section

28

PIONEER NATURAL RESOURCES COMPANY
382, generally determined, subject to certain adjustments, by multiplying (i) the fair market value of such corporation's stock at the time of the ownership change by (ii) a percentage approximately equivalent to the yield on long-term tax-exempt bonds during the month in which the ownership change occurs. Any unused annual limitation may be carried over to later years.
The Company periodically evaluates its unproved oil and gas properties to determine recoverability of its cost and could be required to recognize noncash charges in the earnings of future periods.
As of December 31, 2021, the Company carried unproved oil and gas property costs of $6.1 billion. GAAP requires periodic evaluation of these costs on a project-by-project basis. These evaluations are affected by the results of exploration activities, commodity price outlooks, planned future sales or expiration of all or a portion of the leases and the contracts and permits appurtenant to such projects. If the quantity of potential reserves determined by such evaluations is not sufficient to fully recover the cost invested in each project, the Company will recognize noncash charges in the earnings in the period in which the unproved oil and gas properties is determined to be impaired.
The Company periodically evaluates its goodwill for impairment and could be required to recognize noncash charges in the earnings of future periods.
As of December 31, 2021, the Company had a carrying value for goodwill of $243 million. Goodwill is assessed for impairment annually during the third quarter and whenever facts or circumstances indicate that the carrying value of the Company's goodwill may be impaired, which may require an estimate of the fair values of the reporting unit's assets and liabilities. Those assessments may be affected by (i) positive or negative reserve adjustments, (ii) results of drilling activities, (iii) management's outlook for commodity prices and costs and expenses, (iv) changes in the Company's market capitalization, (v) changes in the Company's weighted average cost of capital and (vi) changes in income taxes. If the fair value of the reporting unit's net assets is not sufficient to fully support the goodwill balance in the future, the Company will reduce the carrying value of goodwill for the impaired value, with a corresponding noncash charge to earnings in the period in which goodwill is determined to be impaired. If incurred, an impairment of the goodwill could result in a material noncash charge to the Company's earnings in the period in which goodwill is determined to be impaired.
Health, Safety and Environmental Risks
The Company's operations are subject to a series of risks arising out of the threat of climate change, energy conservation measures, or initiatives that stimulate demand for alternative forms of energy that could result in increased operating costs, limit the areas in which oil and gas production may occur, and reduce demand for the oil and gas production it provides.
The threat of climate change continues to attract considerable attention in the United States and around the world. Numerous proposals have been made and could continue to be made at the international, national, regional and state levels of government to monitor and limit existing emissions of GHGs as well as to restrict or eliminate such future emissions.
No comprehensive climate change legislation has been implemented at the federal level, but President Biden has made the combat of climate change arising from GHG emissions a priority under his Administration and has issued, and may continue to issue, executive orders or other regulatory initiatives in pursuit of his regulatory agenda. The EPA has adopted rules that, among other things, establish construction and operating permit reviews for GHG emissions from certain large stationary sources, require the monitoring and annual reporting of GHG emissions from certain petroleum and gas system sources, and impose new standards reducing methane emissions from oil and gas operations through limitations on venting and flaring and the implementation of enhanced emission leak detection and repair requirements. In recent years, there has been considerable uncertainty surrounding regulation of methane emissions. During 2020, the former Trump Administration revised performance standards for methane established in 2016 to lessen the impact of those standards and remove the transmission and storage segments from the source category for certain regulations. However, shortly after taking office in 2021, President Biden issued an executive order calling on the EPA to revisit federal regulations regarding methane and establish new or more stringent standards for existing or new sources in the oil and gas sector, including the transmission and storage segments. The U.S. Congress also passed, and President Biden signed into law, a revocation of the 2020 rulemaking, effectively reinstating the 2016 standards. In response to President Biden's executive order, in November 2021, the EPA issued a proposed rule that, if finalized, would establish Quad Ob new source and Quad Oc first-time existing source standards of performance for methane and volatile organic compound ("VOC") emissions in the oil and gas source category. This proposed rule would apply to upstream and midstream facilities at oil and gas well sites, gas gathering and boosting compressor stations, gas processing plants, and transmission and storage facilities. Owners or operators of affected emission units or processes would have to comply with specific standards of performance that may include leak detection using optical gas imaging and subsequent repair requirements, reduction of emissions by 95 percent through capture and control systems, zero-emission requirements, operations and maintenance requirements, and so-called green well completion requirements. The EPA plans to issue a supplemental proposal enhancing this proposed rulemaking in 2022 that will contain additional requirements that were not included in the November 2021 proposed rule. EPA anticipates issuing a final rule before the end of 2022.

29

PIONEER NATURAL RESOURCES COMPANY
Additionally, various states and groups of states have adopted or are considering adopting legislation, regulations or other regulatory initiatives that are focused on such areas as GHG cap and trade programs, carbon taxes, GHG reporting and tracking programs, and restriction of GHG emissions. At the international level, there exists the United Nations-sponsored Paris Agreement, which is a non-binding agreement for nations to limit their greenhouse gas emissions through individually-determined reduction goals every five years after 2020. President Biden announced in April 2021 a new, more rigorous nationally determined emissions reduction level of 50 percent to 52 percent from 2005 levels in economy-wide net GHG emissions by 2030. Moreover, the international community gathered again in Glasgow in November 2021 at the 26th Conference of the Parties ("COP26"), during which multiple announcements (not having the effect of law) were made, including a call for parties to eliminate certain fossil fuel subsidies and pursue further action on non-CO2 GHGs. Relatedly, the United States and European Union jointly announced at COP26 the launch of a Global Methane Pledge, an initiative which over 100 counties joined, committing to a collective goal of reducing global methane emissions by at least 30 percent from 2020 levels by 2030, including "all feasible reductions" in the energy sector. The impacts of these orders, pledges, agreements and any legislation or regulation promulgated to fulfill the United States' commitments under the Paris Agreement, COP26, or other international conventions cannot be predicted at this time.
Governmental, scientific, and public concern over the threat of climate change arising from GHG emissions has resulted in federal political risks in the United States. President Biden has issued several executive orders calling for more expansive action to address climate change and suspend new oil and gas operations on federal lands and waters. The suspension of the federal leasing activities prompted legal action by several states against the Biden Administration, resulting in issuance of a nationwide preliminary injunction by a federal district judge in Louisiana in June 2021, effectively halting implementation of the leasing suspension. The federal government is appealing the district court decision. Other actions adversely affecting the oil and gas industry that may be pursued by the Biden Administration include limiting hydraulic fracturing by banning new oil and gas permitting on federal lands and waters, potentially eliminating certain tax rules (referred to as subsidies) that benefit the oil and gas industry, and imposing restrictions on pipeline infrastructure. Litigation risks are also increasing, as a number of states, municipalities and other plaintiffs have sought to bring suit against oil and gas exploration and production companies in state or federal court, alleging, among other things, that such energy companies created public nuisances by producing fuels that contributed to global warming effects, such as rising sea levels, and therefore, are responsible for roadway and infrastructure damages as a result, or alleging that the companies have been aware of the adverse effects of climate change for some time but defrauded their investors by failing to adequately disclose those impacts. The Company is not currently a defendant in any of these lawsuits, but it could be named in actions making similar allegations. An unfavorable ruling in any such case could significantly impact the Company's operations and could have an adverse impact on its financial condition.
Additionally, the Company's access to capital may be impacted by climate change policies. Shareholders and bondholders that are currently invested in fossil-fuel energy companies are concerned about the potential effects of climate change and may elect in the future to shift some or all of their investments into non-fossil fuel energy related sectors. Institutional lenders who provide financing to fossil-fuel energy companies also have become more attentive to sustainable lending and investment practices that favor "clean" power sources, such as wind and solar, making those sources more attractive, and some of them may elect not to provide funding for fossil fuel energy companies. Many of the largest U.S. banks have made "net zero" carbon emission commitments and have announced that they will be assessing financed emissions across their portfolios and taking steps quantify and reduce those emissions. At COP26, the Glasgow Financial Alliance for Net Zero ("GFANZ") announced that commitments from over 450 firms across 45 countries had resulted in over $130 trillion in capital committed to net zero goals. The various suballiances of GFANZ generally require participants to set short-term, sector-specific targets to transition their financing, investing, and/or underwriting activities to net zero emissions by 2050. These and other developments in the financial sector could lead to some lenders restricting access to capital for or divesting from certain industries or companies, including the oil and gas sector, or requiring that borrowers take additional steps to reduce their GHG emissions. Additionally, there is the possibility that financial institutions may be pressured or required to adopt policies that limit funding for fossil fuel energy companies. In late 2020, the Federal Reserve announced that it had joined the Network for Greening the Financial System ("NGFS"), a consortium of financial regulators focused on addressing climate-related risks in the financial sector. More recently, in November 2021, the Federal Reserve issued a statement in support of the efforts of the NGFS to identify key issues and potential solutions for the climate-related challenges most relevant to central banks and supervisory authorities. While the Company cannot predict what policies may result from these announcements, a material reduction in the capital available to the fossil fuel industry could make it more difficult to secure funding for exploration, development, production, transportation, and processing activities, which could impact the Company's business and operations. Separately, the SEC has also announced that is scrutinizing existing climate-change related disclosures in public filings, increasing the potential for enforcement if the SEC were to allege an issuer's existing climate disclosures misleading or deficient.
Finally, increasing concentrations of GHG in the Earth's atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, droughts, floods, rising sea levels and other climatic

30

PIONEER NATURAL RESOURCES COMPANY
events, as well as chronic shifts in temperature and precipitation patterns. These climatic developments have the potential to cause physical damage to the Company's assets and thus could have an adverse effect on its exploration and production operations. Additionally, changing meteorological conditions, particularly temperature, may result in changes to the amount, timing, or location of demand for energy or its production. While the Company's consideration of changing climatic conditions and inclusion of safety factors in design is intended to reduce the uncertainties that climate change and other events may potentially introduce, its ability to mitigate the adverse impacts of these events depends in part on the effectiveness of its facilities and its disaster preparedness and response and business continuity planning, which may not have considered or be prepared for every eventuality.
The occurrence of any one or more of these developments with respect to climate change initiatives and further restrictions on GHG emissions could have a material adverse effect on the Company's business, financial condition and results of operations.
The nature of the Company's assets and production operations may impact the environment or cause environmental contamination, which could result in material liabilities to the Company.
The Company's assets and production operations may give rise to significant environmental costs and liabilities as a result of the Company's handling of petroleum hydrocarbons and wastes, because of air emissions and water discharges related to its operations, and due to past industry operations and waste disposal practices. The Company's oil and gas business involves the generation, handling, treatment, storage, transport and disposal of wastes, hazardous substances and petroleum hydrocarbons and is subject to environmental hazards, such as oil and produced water spills, NGL and gas leaks, pipeline and vessel ruptures and unauthorized discharges of such wastes, substances and hydrocarbons, that could expose the Company to substantial liability due to pollution and other environmental damage. The Company could also incur costs and liabilities arising out of the unintended release of its flowback water or certain other oilfield fluids that the Company injects or has injected into non-producing formations. Another consequence of such contamination may be lawsuits alleging that its operations have caused damage to neighboring properties or otherwise violated state and federal rules regulating waste disposal. The occurrence of any one or more of these developments could have a material adverse effect on the Company's business, financial condition and results of operations.
The Company's hydraulic fracturing and former sand mining operations may result in silica-related health issues and litigation that could have a material adverse effect on the Company.
The Company routinely conducts hydraulic fracturing in its drilling and completion programs, which activity requires management and use of significant volumes of sand. Additionally, the Company owns and formerly operated certain sand mining operations. The inhalation of respirable crystalline silica dust is associated with the lung disease silicosis. There is evidence of an association between crystalline silica exposure or silicosis and lung cancer and a possible association with other diseases, including immune system disorders, such as scleroderma. These health risks have been, and may continue to be, a significant issue confronting the commercial sand industry. The actual or perceived health risks of mining, processing and handling sand could materially and adversely affect the Company through the threat of product liability or personal injury lawsuits, enacted OSHA silica regulations and increased scrutiny by federal, state and local regulatory authorities. The occurrence of significant silica-related health issues as well as any pending or future claims or inadequacies of insurance coverage or contractual indemnification arising out of such issues could have a material adverse effect on the Company's results of operations.
Increasing attention to ESG matters may impact the Company's business.
Businesses across all industries are facing increasing scrutiny from stakeholders related to their ESG practices. Businesses that do not adapt to or comply with investor or stakeholder expectations and standards, which are continuing to evolve, or businesses that are perceived to have not responded appropriately to the growing concern for ESG issues, regardless of whether there is a legal requirement to do so, may suffer from reputational damage and the business, financial condition, and/or stock price of such business entity could be materially and adversely affected. Increasing attention to climate change, increasing societal expectations on businesses to address climate change, and potential consumer use of substitutes to energy commodities may result in increased costs, reduced demand for the Company's hydrocarbon products, reduced profits, increased investigations and litigation, and negative impacts on its stock price and access to capital markets. Increasing attention to climate change, for example, may result in demand shifts for the Company's hydrocarbon products, additional governmental investigations and private litigation, an increase in shareholder activism as shareholders may attempt to effect changes to the Company's business or governance, whether by shareholder proposals, public campaigns, proxy solicitations or otherwise, or constraints in sources of capital as certain financial institutions, institutional investors and other sources of capital limit or eliminate their investment in oil and gas activities.

31

PIONEER NATURAL RESOURCES COMPANY
As part of the Company's ongoing effort to enhance its ESG efforts, its board of directors has established a Sustainability and Climate Oversight Committee, which is charged with the ongoing oversight of the Company's corporate climate-related risk analysis, as well as its Sustainability Report, Climate Risk Report and other related activities. Additionally, in 2021, to further strengthen the Company's ESG performance, it enhanced its aspirational emissions reduction goals as follows: (i) increased its emissions reduction targets for its methane emissions intensity from a 40 percent reduction to a 75 percent reduction by 2030 and its GHG emissions intensity from a 25 percent reduction to a 50 percent reduction by 2030 and (ii) maintaining a flaring intensity standard of less than one percent of gas produced and to end routine flaring by 2030, with an aspirational goal to achieve it by 2025. While the Company may elect to establish various voluntary ESG targets now or in the future, such targets are aspirational. The Company may not be able to meet such targets in the manner or on such a timeline as initially contemplated, including as a result of unforeseen costs or technical difficulties associated with achieving such results. To the extent the Company elected to pursue such targets and were able to achieve the desired target levels, such achievement may have been accomplished as a result of entering into various contractual arrangements, including the purchase of various credits or offsets that may be deemed to mitigate its ESG impact instead of actual changes in ESG performance. Notwithstanding the Company's election to pursue aspirational targets now or in the future, it may receive pressure from investors, lenders or other groups to adopt more aggressive climate or other ESG-related goals, but the Company cannot guarantee it will be able to implement such goals because of potential costs or technical or operational obstacles.
In addition, organizations that provide information to investors on corporate governance and related matters have developed ratings processes for evaluating business entities on their approach to ESG matters. Currently, there are no universal standards for such scores or ratings, but the importance of sustainability evaluations is becoming more broadly accepted by investors and shareholders. Such ratings are used by some investors to inform their investment and voting decisions. Additionally, certain investors use these scores to benchmark businesses against their peers and if a business entity is perceived as lagging, these investors may engage with such entities to require improved ESG disclosure or performance. Moreover, certain members of the broader investment community may consider a business entity's sustainability score as a reputational or other factor in making an investment decision. Consequently, a low sustainability score could result in exclusion of the Company's stock from consideration by certain investment funds, engagement by investors seeking to improve such scores and a negative perception of the Company's operations by certain investors. Additionally, though the Company believes it can achieve its voluntary ESG targets and goals, any failure to realize or the perception of a failure to realize voluntary targets or long-term goals, could lead to a negative perception of the Company.
Regulatory Risks
The Company's operations are subject to stringent environmental, oil and gas-related and occupational safety and health legal requirements that could increase its costs of doing business and result in operating restrictions, delays or cancellations in the permitting, drilling or completion of oil and gas wells, which could have a material adverse effect on the Company's business, results of operations and financial condition.
The Company's oil and gas exploration and production operations are subject to stringent federal, state and local legal requirements governing, among other things, the drilling of wells (including allocation wells on two or more leaseholds that are not pooled), rates of production, the size and shape of drilling and spacing units or proration units, the transportation and sale of oil, NGLs and gas, the discharging of materials into the environment, environmental protection and occupational safety and health. These requirements may take the form of laws, regulations, and executive actions, and noncompliance with these legal requirements may subject the Company to sanctions, including administration, civil or criminal penalties, remedial cleanups or corrective actions, delays in permitting or performance of projects, natural resource damages and other liabilities. Changes in administrative procedures or authorizations, court decisions, and legislative action with respect to any of these areas, including authorizations for allocation wells, could have a material adverse effect on the Company's anticipated future production, results of operations and financial condition.
In connection with its operations, the Company must obtain and maintain numerous environmental and oil and gas related permits, approvals and certificates from various federal, state and local governmental authorities, and may incur substantial costs in doing so. The need to obtain permits has the potential to delay, curtail or cease the development of oil and gas projects. The Company may in the future be charged royalties on gas emissions or required to incur certain capital expenditures for air pollution control equipment or other air emissions-related issues. For example, in 2015, the EPA under the Obama Administration issued a final rule under the CAA, making the National Ambient Air Quality Standard ("NAAQS") for ground-level ozone more stringent. Since that time, the EPA has issued area designations with respect to ground-level ozone and, on December 31, 2020, published a final action that, upon conducting a periodic review of the ozone standard in accord with CAA requirements, elected to retain the 2015 ozone NAAQS without revision on a going-forward basis. However, several groups have filed litigation over this December 2020 decision, and the Biden Administration has announced plans to reconsider the December 2020 final action in favor of a more stringent ground-level ozone NAAQS. State implementation of the revised

32

PIONEER NATURAL RESOURCES COMPANY
NAAQS could, among other things, require installation of new emission controls on some of the Company's equipment, result in longer permitting timelines, and significantly increase the Company's capital expenditures and operating costs.
In another example, there continues to be uncertainty on the federal government's applicable jurisdictional reach under the CWA over waters of the United States, including wetlands, as the EPA and the U.S. Army Corps of Engineers ("Corps") under the Obama, Trump and Biden Administrations have pursued multiple rulemakings since 2015 in an attempt to determine the scope of such reach. While the EPA and Corps under the Trump Administration issued a final rule in January 2021 narrowing federal jurisdictional reach over waters of the United States, President Biden issued an executive order to further review and assess these regulations consistent with the new administration's policy objectives, following which the EPA and Corps announced plans in June 2021 to initiate a new rulemaking process that would repeal the 2020 rule and restore protections that were in place prior to the 2015. Although the EPA and Corps did not seek to vacate the 2020 rule on an interim basis, two federal district courts in Arizona and New Mexico have vacated the 2020 rule in decisions announced during the third quarter of 2021. While these district court decisions may be appealed, it is clear that the EPA and Corps intend to adopt a more expansive definition for waters of the United States. As an initial step, the agencies published on December 7, 2021 a proposed rulemaking that would put back into place the pre-2015 definition of "waters of the United States." The proposed rule, if adopted would serve as an interim approach to "waters of the United States" and provide the agency with time to develop a subsequent rule that builds upon the currently proposed rule based, in part, on additional stakeholder involvement. To the extent that any new final rule or rules issued by the EPA and Corps under the Biden Administration expands the scope of the CWA's jurisdiction in areas where the Company conducts operations, such developments could delay, restrict or halt the development of projects, result in longer permitting timelines, or increased compliance expenditures or mitigation costs for the Company's operations, which may reduce the Company's rate of production of oil and gas and have a material adverse effect on the Company's business, results of operations and cash flows.
Additionally, the Company's operations are subject to federal and state laws and regulations, including the federal OSHA and comparable state statutes, whose purpose is to protect the health and safety of employees. Among other things, the OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act, and comparable state statutes require that information be maintained concerning hazardous materials used or produced in the Company's operations and that this information be provided to employees, state and local government authorities and citizens.
Compliance with these legal requirements, or any other new environmental or occupational safety and health laws, regulations or executive actions could, among other things, require the Company to install new or modified emission or safety controls on equipment or processes, incur longer permitting timelines, and incur increased capital or operating expenditures, which costs may be significant. Additionally, one or more of these developments could impact the Company's oil and gas exploration, production and development activities, which could have a material adverse effect on its business, results of operations and financial condition.
Laws, regulations and other executive actions or regulatory initiatives regarding hydraulic fracturing could increase the Company's cost of doing business and result in additional operating restrictions, delays or cancellations that could have a material adverse effect on the Company's business, results of operations and financial condition.
The Company routinely conducts hydraulic fracturing in its drilling and completion programs. Hydraulic fracturing is typically regulated by state oil and gas commissions, but the practice continues to attract considerable public, scientific and governmental attention in certain parts of the country, resulting in increased scrutiny and regulation, including by federal agencies.
At the federal level, the EPA asserted federal regulatory authority under the SDWA over certain hydraulic fracturing activities involving the use of diesel fuels and published permitting guidance for such activities. Additionally, the EPA issued a final regulation under the CWA prohibiting discharges to publicly owned treatment works of wastewater from onshore unconventional oil and gas extraction facilities. In late 2016, the EPA released its final report on the potential impacts of hydraulic fracturing on drinking water resources, concluding that "water cycle" activities associated with hydraulic fracturing may impact drinking water resources under certain circumstances. Also, in 2016, the BLM under the Obama Administration published a final rule imposing more stringent standards on hydraulic fracturing on federal lands; however, in late 2018, the BLM, under the Trump Administration, published a final rule rescinding the 2016 final rule. Since that time, litigation challenging the BLM's 2016 final rule and the 2018 final rule has resulted in rescission in federal courts of both the 2016 rule and the 2018 final rule but appeals to those decisions are ongoing.
Notwithstanding these regulatory developments, the Biden Administration has issued executive orders, could issue additional executive orders and could pursue other legislative and regulatory initiatives that restrict hydraulic fracturing activities on federal lands. For example, the Biden Administration issued an order in January 2021 suspending the issuance of

33

PIONEER NATURAL RESOURCES COMPANY
new leases on federal lands and waters pending review and reconsideration of federal oil and gas leasing and permitting practices. The suspension of these federal leasing activities prompted legal action by several states against the Biden Administration, resulting in issuance of a nationwide preliminary injunction by a federal district judge in Louisiana in June 2021, effectively halting implementation of the leasing suspension. The federal government is appealing the district court decision. Separately, the DOI released its report on federal oil and gas leasing and permitting practices in November 2021, following a review of the onshore and offshore federal oil and gas program. The report states an intent to modernize the federal oil and gas leasing program and, in respect of the onshore sector, recommends adjusting royalty rates to ensure that the full value of the tracts being leased are captured and strengthening financial assurance coverage amounts that are more protective of the federal government and taxpayers. Certain of the report recommendations require action by Congress and cannot be implemented unilaterally by the new administration and, thus, the extent to which the Biden Administration will act upon the report's recommendations cannot be predicted at this time. Further constraints may be adopted by the Biden Administration in the future.
At the state level, many states have adopted legal requirements that have imposed new or more stringent permitting, public disclosure or well construction requirements on hydraulic fracturing activities, including in states where the Company's oil and gas exploration and production activities occur. States could also elect to place prohibitions on hydraulic fracturing and local governments may seek to adopt ordinances within their jurisdictions regulating the time, place or manner of drilling activities in general or hydraulic fracturing activities in particular.
Laws and regulations pertaining to protection of threatened and endangered species or to critical habitat, wetlands and natural resources could delay, restrict or prohibit the Company's operations and cause it to incur substantial costs that may have a material adverse effect on the Company's development and production of reserves.
The federal ESA and comparable state laws were established to protect endangered and threatened species. Under the ESA, if a species is listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species' habitat. Similar protections are offered to migratory birds under the Migratory Bird Treaty Act ("MBTA"). The U.S. Fish and Wildlife Service ("FWS"), during the Trump Administration, issued a final rule on January 7, 2021, which clarifies that criminal liability under the MBTA will apply only to actions "directed at" migratory birds, its nests, or its eggs; however, the FWS under the Biden Administration has since published a final rule in October 2021 revoking the January 2021 rule and affirmatively stating that the MBTA prohibits incidental takes of migratory birds. Some of the Company's operations are conducted in areas where protected species or their habitats are known to exist. In these areas, the Company may be obligated to develop and implement plans to avoid potential adverse effects to protected species and their habitats, and the Company may be delayed, restricted or prohibited from conducting operations in certain locations or during certain seasons, such as breeding and nesting seasons, when the Company's operations could have an adverse effect on the species. In addition, the FWS may make new determinations on the listing of species as endangered or threatened under the ESA. The dunes sagebrush lizard and the lesser prairie chicken are examples of species that, if listed as endangered or threatened under the ESA in the future, could impact the Company's operations. The designation of previously unprotected species or the re-designation of under protected species as threatened or endangered in areas where the Company conducts operations could cause the Company to incur increased costs arising from species protection measures or could result in delays, restrictions or prohibitions on its development and production activities that could have a material adverse effect on the Company's ability to develop and produce reserves.
The Company's transportation of gas; sales and purchases of oil, NGLs and gas or other energy commodities and any derivative activities related to such energy commodities, expose the Company to potential regulatory risks.
The FERC, the Federal Trade Commission ("FTC") and the U.S. Commodities Futures Trading Commission ("CFTC") hold statutory authority to monitor certain segments of the physical and futures energy commodities markets relevant to the Company's business. These agencies have imposed broad regulations prohibiting fraud and manipulation of such markets. With regard to the Company's transportation of gas in interstate commerce, physical sales and purchases of oil, NGL, gas or other energy commodities, and any derivative activities related to these energy commodities, the Company is required to observe the market-related regulations enforced by these agencies, which hold substantial enforcement authority. Failure to comply with such regulations, as interpreted and enforced, could result in agency actions that could materially and adversely affect the Company's results of operations and financial condition.
The enactment of derivatives legislation could have a material adverse effect on the Company's ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with its business.
The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") enacted in July 2010, established federal oversight and regulation of the over-the-counter derivatives market and entities, such as the Company, that participate in that market. The Dodd-Frank Act requires the CFTC and the SEC to promulgate rules and regulations for its

34

PIONEER NATURAL RESOURCES COMPANY
implementation. While many Dodd-Frank Act regulations are already in effect, the rulemaking and implementation process is ongoing, and the ultimate effect of the adopted rules and regulations and any future rules and regulations on the Company's business remain uncertain.
In 2021, the CFTC voted to finalize a new set of rules regarding position limits for certain physical commodity derivatives (the "Final Position Limits Rule"). The Final Position Limits Rule establishes new and amended position limits for futures and options contracts in various commodities (including oil and gas) and for swaps that are their economic equivalents. Under the Final Position Limits Rule, certain types of derivative transactions are exempt from these limits, provided that such derivative transactions satisfy the CFTC's requirements for certain enumerated "bona fide" derivative transactions, pass-through swaps and certain anticipatory hedges. The Final Position Limits Rule also includes new exemptions for conditional spot-month positions in gas, preexisting positions acquired in good faith and, in limited circumstances, upon request to the CFTC.
The CFTC has also adopted final rules regarding the aggregation requirements applicable to position limits (such rules, as expanded by the Final Positions Limits Rule, the "Aggregation Rule"). The Aggregation Rule requires the aggregation of positions in commodity futures contracts and the economically equivalent futures, options and swaps held by separate but related entities for purposes of determining compliance with position limits. Absent an applicable exemption, aggregation is required across accounts in which a market participant holds at least a ten percent equity interest or where multiple accounts with identical trading strategies are controlled by such aggregating entity. The CFTC has granted relief from some of the aggregation requirements in the Aggregation Rule until August 12, 2022 for aggregating entities that hold or control the trading of multiple accounts or entities with substantially identical trading strategies unless they hold or control such accounts or entities to willfully evade applicable position limits. The Final Position Limits Rule provides that, by January 21, 2022, market participants need to comply with speculative position limits applicable for commodity futures contracts, other than economically equivalent swaps. Economically equivalent swaps will become subject to position limits under the Final Position Limits Rule on January 1, 2023. These rules may affect both the size of the positions that the Company may hold and the ability or willingness of counterparties to trade with the Company, potentially increasing the costs of transactions. Moreover, such changes could materially reduce the Company's access to derivative opportunities, which could adversely affect revenues or cash flow during periods of low commodity prices. The ultimate effect of these rules and any additional regulations on the Company's business is uncertain.
The CFTC has designated certain interest rate swaps and credit default swaps for mandatory clearing and the associated rules also will require the Company, in connection with covered derivative activities, to comply with clearing and trade-execution requirements or to take steps to qualify for an exemption to such requirements. Although the Company believes it qualifies for the end-user exception from the mandatory clearing requirements for swaps entered to mitigate its commercial risks, the application of the mandatory clearing and trade execution requirements to other market participants, such as swap dealers, may change the cost and availability of the swaps that the Company uses. If the Company's swaps do not qualify for the commercial end-user exception, or if the cost of entering into uncleared swaps becomes prohibitive, the Company may be required to clear such transactions. The ultimate effect of these rules and any additional regulations on the Company's business is uncertain.
In addition, certain banking regulators and the CFTC have adopted final rules establishing minimum margin requirements for uncleared swaps. Although the Company expects to qualify for the end-user exception from margin requirements for swaps entered into to manage its commercial risks, the application of such requirements to other market participants, such as swap dealers, may change the cost and availability of the swaps that the Company uses. If any of the Company's swaps do not qualify for the commercial end-user exception, the posting of collateral could reduce its liquidity and cash available for capital expenditures and could reduce its ability to manage commodity price volatility and the volatility in its cash flows.
The full impact of the Dodd-Frank Act and related regulatory requirements upon the Company's business will not be known until the regulations are fully implemented and the market for derivatives contracts has adjusted. In addition, it is possible that the Biden administration could expand regulation of the over-the-counter derivatives market and the entities that participate in that market through either the Dodd-Frank Act or the enactment of new legislation. The Dodd-Frank Act (and any regulations implemented thereunder) and any new legislation could significantly increase the cost of derivative contracts, materially alter the terms of derivative contracts, reduce the availability of derivatives to protect against risks the Company encounters and reduce the Company's ability to monetize or restructure its existing derivative contracts. Further, the Dodd-Frank Act was enacted, in part, for the purpose of preventing the burdens associated with excessive speculation causing sudden or unreasonable fluctuations or unwarranted changes in the price of an underlying commodity (including oil and gas). The Company's revenues could therefore be materially and adversely affected if a consequence of the Dodd-Frank Act and implementing regulations is to lower commodity prices.

PIONEER NATURAL RESOURCES COMPANY
The European Union and other non-U.S. jurisdictions are implementing regulations with respect to the derivatives market. To the extent the Company transacts with counterparties in foreign jurisdictions or counterparties with other businesses that subject them to regulations in foreign jurisdictions, the Company may become subject to, or otherwise affected by, such regulations. At this time, the impact of such regulations is not clear.
Regulation by the CFTC and banking regulators of the over-the-counter derivatives market and market participants could cause the Company's contract counterparties, which are generally financial institutions and other market participants, to curtail or cease their derivatives activities. The Company believes that these regulatory trends have contributed to a reduction in liquidity of the over-the-counter derivatives market, which could make it more difficult to engage in derivative transactions covering significant volumes of the Company's future production, and which could materially and adversely affect the cost and availability of derivatives to the Company. If the Company reduces its use of derivatives as a result of such regulation, the Company's results of operations may become more volatile and its cash flows may be less predictable, which could materially and adversely affect the Company's ability to plan for and fund capital expenditures. Any of these consequences could have a material adverse effect on the Company, its financial condition and its results of operations.
The Company's bylaws provide, to the fullest extent permitted by law, that the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the exclusive forum for certain legal actions between the Company and its stockholders and that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of causes of action arising under the Securities Act of 1933. These provisions could increase costs to bring a claim, discourage claims or limit the ability of the Company's stockholders to bring a claim in a judicial forum viewed by the stockholders as more favorable for disputes with the Company or the Company's directors, officers or other employees.
The Company's bylaws provide to the fullest extent permitted by law that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) will be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Company, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, other employee, agent or stockholder of the Company to the Company or the Company's stockholders, (c) any action against the Company arising pursuant to any provision of the Delaware General Corporation Law or as to which the Delaware General Corporation Law confers jurisdiction on the Court of Chancery of the State of Delaware, or (d) any action against the Company or any director, officer, other employee or agent of the Company asserting a claim governed by the internal affairs doctrine, including, without limitation, any action to interpret, apply, enforce or determine the validity of the Company's certificate of incorporation or the Company's bylaws. The Company's bylaws also provided that the federal district courts of the United States shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933. Although the Company's bylaws provide for an exclusive forum for causes of action under the Securities Act of 1933, its stockholders will not be deemed to have waived compliance with the federal securities laws and the rules and regulations thereunder. The choice of forum provisions may increase costs to bring a claim, discourage claims or limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with the Company or the Company's directors, officers or other employees, which may discourage such lawsuits against the Company or the Company's directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision contained in the Company's bylaws to be inapplicable or unenforceable in an action, the Company may incur additional costs associated with resolving such action in other jurisdictions.
Risks Associated with Acquisitions
The financial and operational synergies attributable to acquisitions may vary from expectations.
Pioneer may fail to realize the anticipated benefits and synergies expected from acquisitions, which could adversely affect its business, financial condition and operating results. The success of an acquisition will depend, in significant part, on Pioneer's ability to successfully integrate the acquired business and realize the anticipated strategic benefits and synergies from the combination. Actual operating, technological, strategic and revenue synergies, if achieved at all, may be less significant than expected or may take longer to achieve than anticipated. If Pioneer is not able to achieve these objectives and realize the anticipated benefits and synergies expected from an acquisition within the anticipated timing or at all, Pioneer's business, financial condition and operating results may be adversely affected.
Litigation relating to acquisitions could result in substantial costs to the Company.
Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into acquisition, merger or other business combination agreements. Even if such a lawsuit is without merit, defending against these

36

PIONEER NATURAL RESOURCES COMPANY
claims can result in substantial costs and divert the time and resources of management. An adverse judgment could result in monetary damages, which could have a negative impact on the Company's liquidity and financial condition.
The Company, subsidiaries, or persons that have indemnification rights against the Company or its subsidiaries may be named in one or more lawsuits in connection with prior acquisitions. If any such lawsuits are filed, there can be no assurance that the Company and the other defendants will be successful in the outcome of any such pending or any potential future lawsuits. The defense or settlement of any of these potential lawsuits may adversely affect the Company's business, liquidity, financial condition and results of operations.
The Company's future results will suffer if it does not effectively manage its expanded operations.
As a result of acquisitions, the size and geographic footprint of the Company's business will likely increase. The Company's future success will depend, in part, upon its ability to manage this expanded business, which may pose substantial challenges for management, including challenges related to the management and monitoring of new operations and the associated increased costs and complexity. The Company may also face increased scrutiny from governmental authorities as a result of the increase in the size of its business. There can be no assurances that the Company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements or other benefits currently anticipated from acquisitions.

Reserve Estimation Procedures and Audits
The information included in this Report about the Company's proved reserves as of December 31, 2021, 2020 and 2019 is based on evaluations prepared by the Company's engineers and audited by Netherland, Sewell & Associates, Inc. ("NSAI").
Reserve estimation procedures. The Company has established internal controls over reserve estimation processes and procedures to support the accurate and timely preparation and disclosure of reserve estimates in accordance with SEC requirements. These controls include oversight of the reserves estimation reporting processes by Pioneer's Corporate Reserves Group ("Corporate Reserves") and an annual external audit of substantial portions of the Company's proved reserves by NSAI.
Corporate Reserves is staffed with reservoir engineers who prepare reserve estimates using reservoir engineering information technology. Corporate Reserves interacts with the exploration and production functions to ensure all available engineering and geologic data is taken into account prior to establishing or revising an estimate. There is oversight of the reservoir engineers by the Director of Reserves who is in turn subject to direct oversight by the Company's management committee ("MC"), which is comprised of its Chief Executive Officer, Chief Operating Officer, Chief Financial Officer and other executive officers.
All reserve estimates, material assumptions and inputs used in reserve estimates and significant changes in reserve estimates are reviewed for appropriateness and compliance with SEC rules and U.S. GAAP. Annually, the MC reviews the reserve estimates, and any differences with NSAI for the portion of the reserves that it audits, before these estimates are approved. The engineers who participate in the reserve estimation and disclosure process periodically attend training provided by external consultants and through internal Pioneer programs. Additionally, Corporate Reserves has prepared and maintains written policies and guidelines for its staff to reference on reserve estimation and preparation to promote consistency in the preparation of the Company's reserve estimates and compliance with the SEC reserve estimation and reporting rules.
Proved reserves audits. The proved reserves audited by NSAI, in aggregate, represented the following:
As of December 31,
202120202019
Proved reserves audited by NSAI93 %89 %83 %
Pre-tax present value of proved reserves discounted at ten percent audited by NSAI96 %100 %99 %
In connection with the annual reserves audit, NSAI prepared its own estimates of the Company's proved reserves and compared its estimates to those prepared by the Company. NSAI determined that the Company's estimates of reserves were prepared in accordance with the definitions and regulations of the SEC, including the criteria of "reasonable certainty," as it pertains to expectations about the recoverability of reserves in future years, under existing economic and operating conditions, consistent with the definition in Rule 4-10(a)(24) of Regulation S-X. NSAI issued an unqualified audit opinion on the Company's proved reserves as of December 31, 2021, 2020 and 2019, respectively, based upon their evaluation. NSAI concluded that the Company's estimates of proved reserves were, in the aggregate, reasonable and had been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. NSAI's audit report as of December 31, 2021, which should be read in its entirety, is attached as Exhibit 99.1 to this Annual Report on Form 10-K.
Qualifications of proved reserves preparers and auditors. Corporate Reserves is staffed by petroleum engineers with extensive industry experience and is managed by the Director of Reserves, the technical person who is primarily responsible for overseeing the Company's reserves estimates. These individuals meet the professional qualifications of reserves estimators and reserves auditors as defined by the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information. The qualifications of the Director of Reserves include 42 years of international and domestic experience as a petroleum engineer, with 24 years focused on reserves reporting for independent oil and gas companies, including Pioneer. He has an additional 20 years of Permian Basin-focused production engineering, advanced reservoir engineering, petrophysics, consulting and special project research experience with major oil companies. His educational background includes an undergraduate degree in Geological Engineering, with a Petroleum Engineering emphasis.
NSAI provides worldwide petroleum property analysis services for energy clients, financial organizations and government agencies. NSAI was founded in 1961 and performs consulting petroleum engineering services under Texas Board of Professional Engineers Registration No. F-2699. The technical person primarily responsible for auditing the Company's reserves estimates is a Licensed Professional Engineer in the State of Texas and has been practicing consulting petroleum engineering at NSAI since 1993. He graduated with a Bachelor of Science degree in Chemical Engineering in 1983 and meets

or exceeds the education, training and experience requirements set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information.
Technologies used in proved reserves estimates. Proved undeveloped reserves include those reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for completion. Undeveloped reserves may be classified as proved reserves on undrilled acreage directly offsetting development areas that are reasonably certain of production when drilled, or where reliable technology provides reasonable certainty of economic producibility. Undrilled locations may be classified as having undeveloped proved reserves only if an ability and intent has been established to drill the reserves within five years, unless specific circumstances justify a longer time period.
In the context of reserves estimations, reasonable certainty means a high degree of confidence that the quantities will be recovered and reliable technology means a grouping of one or more technologies (including computational methods) that has been field-tested and has been demonstrated to provide reasonable certainty that the results will be consistent and repeatable in the formation being evaluated or in an analogous formation. In estimating proved reserves, the Company uses several different traditional methods such as performance-based methods, volumetric-based methods and analogy with similar properties. In addition, the Company utilizes additional technical analysis such as seismic interpretation, wireline formation tests, geophysical logs and core data to provide incremental support for more complex reservoirs. Information from this incremental support is combined with the traditional technologies outlined above to enhance the certainty of the Company's proved reserve estimates.

As of December 31, 2021, the Company holds 976,000 gross acres (863,000 net acres), of which 961,000 gross acres (852,000 net acres) are located in the Spraberry/Wolfcamp field in the Midland Basin of West Texas. Pioneer is the largest acreage holder in the Spraberry/Wolfcamp field with interests in the northern portion of the play of 749,000 gross acres and its interests in the southern portion of the play, where the Company has a joint venture with Sinochem, comprise 212,000 gross acres. The Parsley Acquisition and DoublePoint Acquisition added 115,000 gross acres and 107,000 gross acres, respectively, to the Company's position in the Midland Basin.
The oil produced from the Spraberry/Wolfcamp field in the Midland Basin is West Texas Intermediate Sweet, and the gas produced is casinghead gas with an average energy content of 1,400 Btu. The oil and gas are produced primarily from six formations, the Spraberry, the Jo Mill, the Dean, the Wolfcamp, the Strawn and the Atoka, at depths ranging from 7,500 feet to 14,000 feet. The Company believes that it has significant resource potential within its Spraberry, Jo Mill and Wolfcamp acreage, based on the Company's extensive geologic data covering the Middle Spraberry, Jo Mill and Lower Spraberry intervals, the Wolfcamp A, B, C and D intervals and the Company's drilling results to-date.

40

PIONEER NATURAL RESOURCES COMPANY
During 2021, the Company successfully completed 445 wells in the northern portion of the Midland Basin, 80 wells in the southern portion of the Midland Basin and 17 wells in the Delaware Basin, which were sold in December 2021 as part of the Delaware Divestiture. In the northern portion of the Midland Basin, 35 percent of the horizontal wells placed on production were Wolfcamp A interval wells, 34 percent were Spraberry interval wells and the remaining 31 percent were primarily Wolfcamp B interval wells. In the southern portion of the Midland Basin, the majority of the wells placed on production were Wolfcamp A and B interval wells. In the Delaware Basin, 65 percent were Wolfcamp A and B interval wells and the remaining 35 percent were in the Bone Spring interval.
The Company continues to complete acreage trades that allow the Company to drill wells with longer laterals, improving the expected returns of the wells. The Company estimates that the acreage trades completed in 2021 added approximately 1.6 million lateral feet to the Company's drilling inventory.
The Company plans to operate 22 to 24 horizontal drilling rigs and approximately six frac fleets in the Midland Basin in 2022. The Company will continue to evaluate its drilling and completions program with future activity levels assessed regularly.
Selected Oil and Gas Information
Production, price and cost data. The price that the Company receives for the oil and gas it produces is largely a function of market supply and demand. Demand is affected by general economic conditions, such as the COVID-19 pandemic, and weather and other seasonal conditions, such as hurricanes and tropical storms. Over or under supply of oil or gas can result in substantial price volatility. Historically, commodity prices have been volatile and the Company expects that volatility to continue in the future. A decline in oil, NGL and gas prices or poor drilling results could have a material adverse effect on the Company's financial position, results of operations, cash flows, quantities of oil and gas reserves that may be economically produced and the Company's ability to access the capital markets.
The following tables set forth production, price and cost data with respect to the Company's properties. These amounts represent the Company's historical results of operations without making pro forma adjustments for any acquisitions, divestitures or drilling activity that occurred during the respective years. The production amounts will not match the proved reserve volume tables in "Unaudited Supplementary Information" included in "Item 8. Financial Statements and Supplementary Data" because field fuel volumes are included in the proved reserve volume tables. Because of normal production declines, increased or decreased drilling activities and the effects of acquisitions or divestitures, the historical information presented below should not be interpreted as being indicative of future results.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
Parsley Acquisition and DoublePoint Acquisition
The Company regularly seeks to acquire or trade acreage that complements its operations, provides exploration and development opportunities, increases the lateral length of future horizontal wells and provides superior returns on investment.
On May 4, 2021, the Company completed the acquisition of Double Eagle III Midco 1 LLC in exchange for 27 million shares of Pioneer common stock representing stock consideration transferred of $4.2 billion, $1.0 billion of cash and the assumption of $890 million of debt. The DoublePoint Acquisition was accounted for as a business combination, with the fair value of the acquisition consideration allocated to the acquisition date fair value of assets acquired and liabilities assumed. The results of operations attributable to the assets acquired in the DoublePoint Acquisition were included in the Company's consolidated financial statements beginning in May 2021.
On January 12, 2021, the Company completed the acquisition of Parsley Energy, Inc., a Delaware corporation that previously traded on the NYSE under the symbol "PE", pursuant to the Agreement and Plan of Merger, dated as of October 20, 2020, among Pioneer, certain of its subsidiaries, Parsley and Parsley's subsidiary, Parsley Energy, LLC. The Parsley Acquisition was accounted for as a business combination, with the fair value of the acquisition consideration allocated to the acquisition date fair value of assets acquired and liabilities assumed. As acquisition consideration, the Company issued 52 million shares of Pioneer common stock (representing stock consideration transferred of $6.9 billion) and assumed $3.2 billion of Parsley's debt. The results of operations attributable to the assets acquired in the Parsley Acquisition were included in the Company's consolidated financial statements beginning on January 12, 2021.
See Note 3 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Delaware Divestiture and Glasscock Divestiture
The Company regularly reviews its asset base to identify nonstrategic assets, the disposition of which would increase capital resources available for other activities, create organizational and operational efficiencies and further the Company's objective of maintaining a strong balance sheet to ensure financial flexibility.
In December 2021, the Company completed the divestiture of its Delaware Basin assets to Continental Resources, Inc. for cash proceeds of $3.1 billion, after normal closing adjustments. The sale of these assets resulted in a pretax loss of $1.1 billion.
In October 2021, the Company completed the sale of 20,000 net acres in western Glasscock County to Laredo Petroleum, Inc. in exchange for $137 million in cash and 960 thousand shares of Laredo's common stock representing total consideration transferred of $206 million, after normal closing adjustments. The sale of these assets resulted in a pretax gain of $1 million.
See Note 3 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Financial and Operating Performance
The Company's financial and operating performance for 2021 included the following highlights:
Net income attributable to common stockholders was $2.1 billion ($8.61 per diluted share) for the year ended December 31, 2021, as compared to a net loss of $200 million ($1.21 per diluted share) in 2020. The primary components of the $2.3 billion increase in earnings attributable to common stockholders include:
a $7.9 billion increase in oil and gas revenues, primarily due to an 89 percent increase in average realized commodity prices per BOE as a result of higher commodity prices in 2021 due to the continued recovery in oil and gas demand from levels achieved earlier in the COVID-19 pandemic, and a 68 percent increase in daily sales volumes due to additional production from the Company's successful horizontal drilling program in the Permian Basin, the Parsley Acquisition and the DoublePoint Acquisition;
partially offset by:
a $1.9 billion decrease in derivative results, primarily due to changes in forward commodity prices, the cash settlement of derivative positions in accordance with their terms and liquidating certain of the Company's 2022 commodity derivative contracts prior to their maturities;

52

PIONEER NATURAL RESOURCES COMPANY
the aforementioned loss of $1.1 billion that was recognized in 2021 associated with the sale of the Company's Delaware Basin assets;
a $994 million increase in production costs, including taxes, primarily attributable to (i) increased costs related to the production added from the Parsley Acquisition and the DoublePoint Acquisition and (ii) the increase in production taxes as a result of the aforementioned 89 percent increase in average realized commodity prices per BOE;
an $859 million increase in DD&A expense, primarily due to the aforementioned increase in daily sales volumes; and
a $689 million increase in income taxes, primarily due to the increase in earnings in 2021 compared to 2020.
During 2021, average daily sales volumes increased on a BOE basis by 68 percent to 617,332 BOEPD, as compared to 367,253 BOEPD during 2020, primarily due to the Company's successful Spraberry/Wolfcamp horizontal drilling program, the Parsley Acquisition and the DoublePoint Acquisition.
Average oil and NGL prices per Bbl and average gas prices per Mcf increased to $67.60, $32.70 and $3.85, respectively, in 2021, as compared to $37.24, $15.62 and $1.73, respectively, in 2020.
Cash provided by operating activities increased during 2021 to $6.1 billion, as compared to $2.1 billion for 2020. The increase in net cash flow provided by operating activities in 2021, as compared to 2020, is primarily due to the aforementioned increase in oil and gas revenues as a result of higher commodity prices and sales volumes partially offset by (i) additional cash used in derivative activities, (ii) an increase in production costs, including taxes, due to the aforementioned increase in costs attributable to the production added by the Parsley Acquisition and the DoublePoint Acquisition and production taxes attributable to higher commodity prices, and (iii) one-time Parsley Acquisition and DoublePoint Acquisition cash transaction-related costs.
As of December 31, 2021 and 2020, the Company's net debt to book capitalization was 12 percent and 14 percent, respectively.
Impact of the COVID-19 Pandemic
The COVID-19 pandemic resulted in a severe worldwide economic downturn, significantly disrupting the demand for oil throughout the world, and created significant volatility, uncertainty and turmoil in the oil and gas industry. The decrease in demand for oil, combined with pressures on the global supply-demand balance for oil and related products, resulted in oil prices declining significantly in late February 2020. Since mid-2020, oil prices have improved, with demand steadily increasing despite the uncertainties surrounding the COVID-19 variants, which have continued to inhibit a full global demand recovery. In addition, worldwide oil inventories are, from a historical perspective, very low and supply increases from OPEC, Russia and other oil producing nations are not expected to be sufficient to meet forecasted oil demand growth in 2022 and 2023, with many OPEC countries not able to produce at their OPEC agreed upon quota levels due to their lack of capital investments over the past few years in developing incremental oil supplies. Global oil price levels will ultimately depend on various factors and consequences beyond the Company's control, such as (i) the effectiveness of responses to combat the COVID-19 virus and their impact on domestic and worldwide demand, (ii) the ability of OPEC, Russia and other oil producing nations to manage the global oil supply, (iii) the timing and supply impact of any Iranian sanction relief on Iran's ability to export oil, (iv) additional actions by businesses and governments in response to the pandemic, (v) the global supply chain constraints associated with manufacturing delays, and (vi) political stability of oil consuming countries.
The Company continues to assess the impact of the COVID-19 pandemic on the Company and may modify its response as the impact of COVID-19 continues to evolve.

First Quarter 2022 Outlook
Based on current estimates, the Company expects the following operating and financial results for the first quarter of 2022:
Three Months Ending March 31, 2022
Guidance
($ in millions, except per BOE amounts)
Average daily production (MBOE)620 - 645
Average daily oil production (MBbls)348 - 363
Production costs per BOE$9.25 - $10.75
DD&A per BOE$10.50 - $12.00
Exploration and abandonments expense$10 - $20
General and administrative expense$68 - $78
Accretion of discount on asset retirement obligations$2 - $5
Interest expense$36 - $41
Other expense$15 - $30
Cash flow impact from firm transportation (a)$(55) - $(25)
Current income tax provision (benefit)$10 - $20
Effective tax rate22% - 27%
_____________________
(a)The cash flow impact from firm transportation is primarily based on the forecasted differential between WTI oil prices and Brent oil prices less the costs to transport purchased oil from the areas of the Company's production to the Gulf Coast. To the extent that the Company's Gulf Coast sales of purchased oil does not cover the purchase price and associated firm transport costs, the Company's results of operations will reflect the negative cash flow impact attributable to the shortfall.
2022 Capital Budget
The Company's capital budget for 2022 is expected to be in the range of $3.3 billion to $3.6 billion, consisting of drilling and completion related activities, including additional tank batteries and saltwater disposal facilities, and $85 million for water infrastructure and vehicles. The 2022 capital budget excludes acquisitions, asset retirement obligations, capitalized interest, geological and geophysical general and administrative expense and corporate facilities.
The 2022 capital budget is expected to be funded from operating cash flow, and, if necessary, from cash and cash equivalents on hand or borrowings under the Company's Credit Facility.
Results of Operations
Results of operations should be read together with the Company's consolidated financial statements and related notes included in "Item 8. Financial Statements and Supplementary Data" of this Annual Report on Form 10-K. See the Company's Annual Report on Form 10-K for the year ended December 31, 2020 for a discussion of the Company's 2020 results of operations as compared to the Company's 2019 results of operations.

Oil and gas revenues. The Company's revenues are derived from sales of oil, NGL and gas production. Increases or decreases in the Company's revenues, profitability and future production are highly dependent on commodity prices. Prices are market driven and future prices will fluctuate due to supply and demand factors, availability of transportation, seasonality, geopolitical developments and economic factors, among other items.

(a)Gas production excludes gas produced and used as field fuel.
Average daily sales volumes per BOE increased for the year ended December 31, 2021, as compared to 2020, primarily due to the Company's successful Spraberry/Wolfcamp horizontal drilling program, combined with the production added from the Parsley Acquisition and the DoublePoint Acquisition.
The oil, NGL and gas prices reported by the Company are based on the market prices received for each commodity. Commodity prices for year ended December 31, 2021, as compared to 2020, increased due to the continued recovery in oil, NGL and gas demand from levels achieved earlier in the COVID-19 pandemic. The average prices are as follows:
 Year Ended December 31,

Net sales of purchased commodities. The Company enters into pipeline capacity commitments in order to secure available oil, NGLs and gas transportation capacity from the Company's areas of production and secure diesel supply from the Gulf Coast to the Company's operations in the Permian Basin. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets, and to satisfy unused gas pipeline capacity commitments. Revenues and expenses from these transactions are generally presented on a gross basis in sales of purchased commodities and purchased commodities expense in the accompanying consolidated statements of operations as the Company acts as a principal in the transaction by assuming both the risks and rewards of ownership, including credit risk, of the commodities purchased and the responsibility to deliver the commodities sold. In conjunction with the Company's downstream sales, the Company also enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production to downstream sales points. The transportation costs associated with these transactions are included in purchased commodities expense.

The change in net sales of purchased commodities for the year ended December 31, 2021, as compared to 2020, is primarily due to a $74 million loss during the first quarter of 2020 attributable to oil that was purchased and in transit via pipeline to the Gulf Coast or in Gulf Coast storage at the end of January 2020 and February 2020, and was subsequently sold in February 2020 and March 2020, respectively, at lower prices. The change was also impacted by a decrease in margins on the Company's downstream Gulf Coast refinery and export oil sales for the year ended December 31, 2021, as compared to 2020.
Firm transportation payments on excess pipeline capacity are included in other expense in the accompanying consolidated statements of operations. See Note 16 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

Interest and other income (loss), net$23 $(67)$90 
The increase in interest and other income (loss) for the year ended December 31, 2021, as compared to 2020, is primarily due to (i) a noncash net gain of $12 million attributable to the change in fair value of the Company's investment in affiliates, as compared to a noncash net loss of $64 million for the same period in 2020 and (ii) a $42 million noncash loss in 2020 attributable to the decrease in fair value of contingent consideration associated with the Company's sale of its South Texas Eagle Ford assets ("South Texas Divestiture") in May 2019, partially offset by (i) a $15 million decrease in severance and sales tax refunds and (ii) an $11 million decrease in fair value of the Company's short-term investment in Laredo shares in 2021.

(a)Includes $521 million of losses attributable to the early settlement of certain 2022 oil and gas commodity derivatives, of which the Company recognized $508 million of such in losses during the fourth quarter of 2021 related to (i) the termination of certain of its 2022 oil and gas commodity derivative positions and (ii) entering into equal and offsetting oil and gas commodity derivative trades, which had the net effect of eliminating certain of its 2022 derivative positions. The Company will make cash payments of $328 million during 2022 to settle the deferred obligations associated with the offsetting derivatives.
The Company primarily utilizes commodity swap contracts, collar contracts, collar contracts with short puts and basis swap contracts to (i) reduce the effect of price volatility on the commodities the Company produces and sells or consumes and (ii) support the Company's capital budgeting and expenditure plans. The Company uses marketing derivatives to diversify its oil pricing to Gulf Coast and international markets. The Company also, from time to time, utilizes interest rate contracts to reduce the effect of interest rate volatility on the Company's indebtedness.

_____________________
(a)Lease operating expense and workover costs represent the components of oil and gas production costs over which the Company has management control.
(b)Gathering, processing and transportation expense represents the costs to (i) gather, process, transport and fractionate the Company's gas and NGLs to a point of sale and, to a lesser extent, (ii) gather and transport certain of the Company's oil production to a point of sale.
(c)Net natural gas plant income represents the earnings from the Company's ownership share of gas processing facilities that gather and process the Company's and third party gas.
The change in the Company's production costs per BOE for the year ended December 31, 2021, as compared to 2020, is due to the following:
Lease operating expense per BOE decreased for the year ended December 31, 2021, as compared to 2020, primarily due to (i) operational synergies achieved from the Parsley Acquisition beginning in January 2021 and the DoublePoint Acquisition beginning in May 2021, partially offset by fuel, electricity and labor-related price increases;
Gathering, processing and transportation expense per BOE increased for the year ended December 31, 2021, as compared to 2020, primarily due to (i) increased gas and NGL prices during 2021 that resulted in increased gas

processing costs for those contractual volumes retained by the processor as payment for their services, (ii) increased gas processing and transportation costs as a result of higher electricity costs during Winter Storm Uri in February 2021 and (iii) the assumption of Parsley Acquisition and DoublePoint Acquisition contracts that had higher gathering, processing and transportation costs on a per BOE basis;
Workover costs per BOE increased for the year ended December 31, 2021, as compared to 2020, due to an increase in workover activity as a result of improved commodity prices being realized in 2021, which increased the economic benefit of repairing certain of the Company's oil and gas wells; and
Net natural gas plant income per BOE increased for the year ended December 31, 2021, as compared to 2020, primarily due to improved gas and NGL prices.

Production and ad valorem taxes$651 $242 $409 
In general, production taxes and ad valorem taxes are directly related to commodity price changes; however, Texas ad valorem taxes are based upon prior year commodity prices, whereas production taxes are based upon current year commodity prices.
Production and ad valorem taxes per BOE are as follows:
 Year Ended December 31,

Production taxes per BOE$2.41 $1.17 106 %
Ad valorem taxes per BOE0.48 0.64 (25 %)
$2.89 $1.81 60 %
Production taxes per BOE increased for the year ended December 31, 2021, as compared to 2020, primarily due to the aforementioned increase in oil, NGL and gas commodity prices. The decrease in ad valorem taxes per BOE for the year ended December 31, 2021, as compared to 2020, is primarily due to lower prior year commodity prices that were used to determine current year ad valorem taxes.

The decrease in both DD&A per BOE and depletion expense per BOE for the year ended December 31, 2021, as compared to 2020, is primarily due to additions of proved reserves attributable to (i) the Company's successful Spraberry/Wolfcamp horizontal drilling program, (ii) the Parsley Acquisition and the Double Point Acquisition and (iii) improved commodity prices (which has the effect of extending the economic life of producing wells). In addition, the DD&A per BOE and depletion expense per BOE attributable to the Parsley Acquisition and the DoublePoint Acquisition were lower than the Company's respective 2020 per BOE amounts.

The increase in geological and geophysical costs for the year ended December 31, 2021, as compared to 2020, was primarily due to the relicensing of certain Parsley seismic data in connection with the Parsley Acquisition.
The decrease in leasehold abandonments costs for the year ended December 31, 2021, as compared to 2020, was primarily due to the abandonment of certain unproved properties during 2020 that the Company no longer planned to drill before the leases expired.
During 2021 and 2020, the Company drilled and evaluated 488 and 242 exploratory/extension wells, respectively, with 100 percent successfully completed as discoveries.

$292 $244 $48 
The change in noncash general and administrative expense for the year ended December 31, 2021, as compared to 2020, was primarily due to (i) market fluctuations in the Company's deferred compensation obligation as a result of mark-to-market valuation changes attributable to the Company's deferred compensation plan assets and (ii) an increase in noncash charitable contributions.
The change in cash general and administrative expense for the year ended December 31, 2021, as compared to 2020, was primarily due to (i) the incremental costs assumed in the Parsley Acquisition and DoublePoint Acquisition and (ii) the reinstatement of certain employee benefits during 2021 that were temporarily suspended during 2020 in response to the COVID-19 pandemic.
Total general and administrative expense per BOE is as follows:

The decrease in general and administrative expense per BOE for the year ended December 31, 2021, as compared to 2020, reflects the general and administrative synergies achieved from the Parsley Acquisition beginning in January 2021 and the DoublePoint Acquisition beginning in May 2021. The Company added significant sales volumes from the acquisitions with limited associated incremental general and administrative costs being added.

Noncash interest expense$10 $34 $(24)
Cash interest expense151 95 56 
$161 $129 $32 
The decrease in noncash interest expense for the year ended December 31, 2021, as compared to 2020, is primarily due to the adoption of Accounting Standards Update ("ASU") 2020-06, effective January 1, 2021, which reversed the debt discount recorded to additional paid-in capital upon issuance of the Company's $1.3 billion principal amount of Convertible Notes to long-term debt. Therefore, noncash interest expense decreased primarily due to a $28 million decrease in amortization associated with the discount attributable to the issuance of the Convertible Notes prior to the adoption of ASU 2020-06. See Note 7 of Notes to Consolidated Financial Statements in "Item 1. Financial Statements" for additional information.
The increase in cash interest expense is primarily due to (i) the changes in long-term debt as a result of the Parsley Acquisition and DoublePoint Acquisition (see "Liquidity and Capital Resources" below for additional information) and (ii) the issuance of $1.3 billion of Convertible Notes in May 2020 and $1.1 billion of 1.900% senior notes due 2030 in August 2020, partially offset by (i) the partial repayment of $360 million of the Company's 3.450% senior notes due 2021, $356 million of its 3.950% senior notes due 2022 and $9 million of its 7.200% senior notes due 2028 as a result of the Company's tender offer for these notes in May 2020 and (ii) the repayment of its 3.450% senior notes, with a remaining debt principal balance of $140 million, that matured in January 2021.
The weighted average cash interest rate on the Company's indebtedness for the year ended December 31, 2021 decreased to 1.9 percent, as compared to 2.2 percent for the year ended December 31, 2020.

Liquidity and Capital Resources
Liquidity. The Company's primary sources of short-term liquidity are (i) cash and cash equivalents, (ii) net cash provided by operating activities, (iii) sales of investments, (iv) unused borrowing capacity under its Credit Facility, (v) issuances of debt or equity securities and (vi) other sources, such as sales of nonstrategic assets. On January 12, 2021, the Company entered into the First Amendment to Credit Agreement, with the primary changes being to increase the aggregate loan commitments from $1.5 billion to $2.0 billion, extend the maturity of the Credit Facility to January 12, 2026 and nominally adjust the drawn and undrawn pricing.
The Company's short-term and long-term liquidity requirements consist primarily of (i) capital expenditures, (ii) acquisitions of oil and gas properties, (iii) payments of contractual obligations, including debt maturities, (iv) dividends and share repurchases, (v) income taxes and (vi) working capital obligations. Funding for these requirements may be provided by any combination of the Company's sources of liquidity. Although the Company expects that its sources of funding will be adequate to fund its 2022 liquidity requirements, no assurance can be given that such funding sources will be adequate to meet the Company's future needs.
During the year ended December 31, 2021, the Company enhanced its liquidity position by refinancing a portion of the debt acquired in the Parsley Acquisition and the DoublePoint Acquisition, issuing new debt and increasing the borrowing capacity under the Credit Facility, with the combined objective of increasing liquidity, extending the Company's debt maturities and lowering the Company's future cash interest expense on long-term debt.
2022 capital budget. The Company's capital budget for 2022 is expected to be in the range of $3.3 billion to $3.6 billion, consisting of drilling and completion related activities, including additional tank batteries and saltwater disposal facilities, and $85 million for water infrastructure and vehicles. The 2022 capital budget excludes acquisitions, asset retirement obligations, capitalized interest, geological and geophysical general and administrative expense and corporate facilities.
The 2022 capital budget is expected to be funded from operating cash flow, and, if necessary, from cash and cash equivalents on hand or borrowings under the Company's Credit Facility.
Capital resources. As of December 31, 2021, the Company had no outstanding borrowings under its Credit Facility, leaving $2.0 billion of unused borrowing capacity. The Company was in compliance with all of its debt covenants as of December 31, 2021. The Company also had unrestricted cash on hand of $3.8 billion as of December 31, 2021. See the Company's Annual Report on Form 10-K for the year ended December 31, 2020 for a discussion of the Company's 2020 capital resources as compared to the Company's 2019 capital resources.
Sources and uses of cash in 2021, as compared to 2020, are as follows:

Net cash used in investing activities$(869)$(1,668)$(799)
Net cash provided by (used in) financing activities$(2,807)$381 $(3,188)
Operating activities. The increase in net cash flow provided by operating activities in 2021, as compared to 2020, is primarily due to an increase in oil and gas revenues as a result of higher commodity prices and sales volumes attributable to the Company's successful Spraberry/Wolfcamp horizontal drilling program and production added by the Parsley Acquisition and the DoublePoint Acquisition, partially offset by (i) additional cash used in derivative activities, (ii) an increase in production costs, including taxes, due to an increase in costs associated with the production added by the Parsley Acquisition and the DoublePoint Acquisition and production taxes attributable to higher commodity prices and (iii) one-time Parsley Acquisition and DoublePoint Acquisition cash transaction-related costs.
Investing activities. The decrease in net cash flow used in investing activities during 2021, as compared to 2020, was primarily due to the Delaware Divestiture proceeds in 2021 of $3.1 billion, after normal closing adjustments, and $117 million of net cash acquired in the Parsley Acquisition, partially offset by an increase in additions to oil and gas properties of $1.6 billion and $943 million of net cash used in the DoublePoint Acquisition.

PIONEER NATURAL RESOURCES COMPANY
Financing activities. The Company's significant financing activities are as follows:
2021: The Company (i) received proceeds from the issuance of 0.550% senior notes due 2023, net of $4 million of issuance costs and discounts, of $746 million, (ii) received proceeds from the issuance of 0.750% senior callable notes due 2024, 1.125% senior notes due 2026 and 2.150% senior notes due 2031, net of $24 million of issuance costs and discounts, of $2.5 billion, (iii) borrowed and repaid $650 million on the Company's Credit Facility, (iv) repaid the Parsley and DoublePoint credit facilities, which had outstanding balances of $397 million and $240 million, respectively, (v) repaid $140 million associated with the maturity of its 3.450% senior notes due in January 2021, (vi) used proceeds from the May 2021 Senior Notes Offering to pay $731 million to redeem DoublePoint's 7.750% senior notes due 2025, (vii) used proceeds from the January 2021 Senior Notes Offering to pay $1.6 billion to redeem Parsley's 5.250% senior notes due 2025, Parsley's 5.375% senior notes due 2025 and Jagged Peak's 5.875% senior notes due 2026, (viii) paid $852 million to purchase a portion of Parsley's 5.625% senior notes due 2027 and Parsley's 4.125% senior notes due 2028 pursuant to a cash tender offer, (ix) paid dividends of $1.6 billion, (x) repurchased $269 million of its common stock and (xi) paid $164 million of other liabilities.
2020: The Company (i) received $1.1 billion from the issuance of 1.900% senior notes, net of issuance costs and discounts, (ii) received $1.3 billion from the issuance of the 0.250% convertible senior notes, net of issuance fees, (iii) paid $113 million to enter into capped call transactions with certain financial institution counterparties associated with the convertible senior notes issuance, (iv) paid an aggregate total of $748 million associated with the early repayment of a portion of the 3.450% senior notes due 2021, 3.950% senior notes due 2022 and 7.200% senior notes due 2028, (v) repaid $450 million associated with the maturity of its 7.500% senior notes in January 2020, (vi) paid dividends of $346 million, (vii) repurchased $176 million of its common stock and (viii) paid $173 million of other liabilities.
Dividends/distributions. During the year ended December 31, 2021, the Company's board of directors authorized the payment of base dividends of $487 million or $2.23 per common share, compared to $346 million or $2.09 per common share during the year ended December 31, 2020.
In addition to its base dividend program, beginning in the second quarter of 2021, the Company implemented a variable dividend strategy whereby the Company pays a quarterly variable dividend of up to 75 percent of the prior quarter's free cash flow remaining after the payment of that quarter's base dividend. Free cash flow is a non-GAAP financial measure. As used by the Company, free cash flow is defined as net cash provided by operating activities, adjusted for (i) changes in operating assets and liabilities (ii) cash transaction costs associated with acquisitions and (iii) deferred obligations on certain commodity derivative contracts, less capital expenditures. The Company believes this non-GAAP measure is a financial indicator of the Company's ability to internally fund acquisitions, debt maturities, dividends and share repurchases after capital expenditures. Capital expenditures exclude acquisitions, asset retirement obligations, capitalized interest, geological and geophysical general and administrative expenses, information technology capital investments and additions to corporate facilities. During the year ended December 31, 2021, the Company declared and paid variable dividends of $1.1 billion, or $4.53 per common share.
On February 16, 2022, the board of directors of the Company declared a quarterly base dividend of $0.78 per share and a quarterly variable dividend of $3.00 per share for shareholders of record on February 28, 2022, with a payment date of March 14, 2022. Future base and variable dividends are at the discretion of the Company's board of directors, and, if declared, the board of directors may change the dividend amount based on the Company's outlook for commodity prices, liquidity, debt levels, capital resources, free cash flow or other factors. The Company can provide no assurance that dividends will be authorized or declared in the future or as to the amount of any future dividends. Any future variable dividends, if declared and paid, will fluctuate based on the Company's free cash flow, which will depend on a number of factors beyond the Company's control, including commodity prices.
Off-balance sheet arrangements. From time to time, the Company enters into arrangements and transactions that can give rise to material off-balance sheet obligations of the Company. As of December 31, 2021, the material off-balance sheet arrangements and transactions that the Company had entered into included (i) firm purchase, transportation, storage and fractionation commitments, (ii) open purchase commitments and (iii) contractual obligations for which the ultimate settlement amounts are not fixed and determinable. The contractual obligations for which the ultimate settlement amounts are not fixed and determinable include (a) derivative contracts that are sensitive to future changes in commodity prices or interest rates, (b) gathering, processing and transportation commitments on uncertain volumes of future throughput and (c) indemnification obligations following certain divestitures.

PIONEER NATURAL RESOURCES COMPANY
In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty and income taxes. Also associated with its divestiture transactions, the Company has issued and received guarantees to facilitate the transfer of contractual obligations, such as firm transportation agreements or gathering and processing arrangements. The Company does not recognize a liability if the fair value of the obligation is immaterial or the likelihood of making payments under these guarantees is remote.
Other than the off-balance sheet arrangements described above, the Company has no transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect the Company's liquidity or availability of or requirements for capital resources. The Company expects to enter into similar contractual arrangements in the future and additional firm purchase, transportation, storage and fractionation arrangements, in order to support the Company's business plans. See Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Convertible senior notes. In May 2020, the Company issued $1.3 billion principal amount of convertible senior notes due 2025. The Convertible Notes bear a fixed interest rate of 0.250% per year, with interest payable on May 15 and November 15 of each year. The Convertible Notes will mature on May 15, 2025, unless earlier redeemed, repurchased or converted. The Convertible Notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.
The Convertible Notes are convertible into shares of the Company's common stock at an adjusted conversion rate of 9.3647 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes (subject to further adjustment pursuant to the terms of the notes indenture), which represents an adjusted conversion price of $106.78 per share (subject to further adjustment pursuant to the terms of the notes indenture) as of December 31, 2021. As a result of the quarterly base and variable dividends declared through December 31, 2021, the Conversion Rate increased from the initial rate of 9.1098 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes and the Conversion Price decreased from $109.77. Future declarations of quarterly base dividends in excess of $0.55 per common share and declarations of future variable dividends, as previously described, will cause further adjustments to the Conversion Rate and the Conversion Price pursuant to the terms of the notes indenture. Upon conversion, the Convertible Notes may be settled in cash, shares of the Company's common stock or a combination thereof, at the Company's election.
Holders of the Convertible Notes may convert their notes at their option prior to February 15, 2025 under the following circumstances:
during the quarter following any quarter during which the last reported sales price of the Company's common stock for at least 20 of the last 30 consecutive trading days of such quarter exceeds 130 percent of the Conversion Price;
during the five-day period following any five consecutive trading day period when the trading price of the Convertible Notes is less than 98 percent of the price of the Company's common stock times the Conversion Rate;
upon notice of redemption by the Company; or
upon the occurrence of specified corporate events, including certain consolidations or mergers.
On or after February 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time. The Company may not redeem the Convertible Notes prior to May 20, 2023, and after such date, may redeem the Convertible Notes only if the last reported sale price of the Company's common stock has been at least 130 percent of the Conversion Price for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides the notice of redemption. The redemption price is equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest.
During the last 30 consecutive trading days of the fourth quarter of 2021, the last reported sales prices of the Company's common stock exceeded 130 percent of the Conversion Price for at least 20 trading days, causing the Convertible Notes to become convertible at the option of the holders during the three month period ending March 31, 2022. The Company reserves its right under the notes indenture to elect to settle the Convertible Notes in cash, shares of the Company's common stock or a combination of cash and common stock.
Contractual obligations. The Company's contractual obligations include long-term debt, leases (primarily related to contracted drilling rigs, equipment and office facilities), capital funding obligations, derivative obligations, firm transportation, storage and fractionation commitments, minimum annual gathering, processing and transportation commitments and other liabilities (including retained obligations associated with divestitures and postretirement benefit obligations). Other joint owners in the properties operated by the Company could incur portions of the costs represented by these commitments.

PIONEER NATURAL RESOURCES COMPANY
Firm commitments. The Company has short-term and long-term firm purchase, gathering, processing, transportation, fractionation and storage commitments representing take-or-pay agreements, which include contractual commitments (i) to purchase sand, water and diesel for use in the Company's drilling and completion operations, (ii) with midstream service companies and pipeline carriers for future gathering, processing, transportation, fractionation and storage and (iii) with oilfield services companies that provide drilling and pressure pumping services. The Company does not expect to be able to fulfill all of its short-term and long-term firm transportation volume obligations from projected production of available reserves; consequently, the Company plans to purchase third party volumes to satisfy its firm transportation commitments if it is economic to do so; otherwise, it will pay demand fees for any commitment shortfalls. The Company also has open purchase commitments for inventories, materials and other property and equipment ordered, but not received, as of December 31, 2021. See "Item 2. Properties" and Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Long-term debt. As of December 31, 2021, the Company's outstanding debt is comprised of senior notes, including senior notes issued by Parsley Energy, Inc and Parsley LLC, and convertible senior notes. The senior notes and convertible senior notes issued by the Company rank equally, but are structurally subordinated to all obligations of the Company's subsidiaries. See Note 7 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Leases. The Company's short-term and long-term lease obligations primarily relate to contracted drilling rigs, storage tanks, equipment and office facilities. See Note 10 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Derivative obligations. The Company's commodity and marketing derivative contracts are periodically measured and recorded at fair value and continue to be subject to market and credit risk. As of December 31, 2021, these contracts represented net liabilities of $563 million. The ultimate liquidation value of the Company's commodity price derivatives will be dependent upon actual future commodity prices, which may differ materially from the inputs used to determine the derivatives' fair values as of December 31, 2021. See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for additional information.
Other liabilities. The Company's other liabilities represent current and noncurrent other liabilities that are primarily comprised of litigation and environmental contingencies, asset retirement obligations and other obligations for which neither the ultimate settlement amounts nor their timings can be precisely determined in advance. See Note 9 and Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Book capitalization and current ratio. The Company's net book capitalization as of December 31, 2021 was $25.9 billion, consisting of cash and cash equivalents of $3.8 billion, debt of $6.9 billion and equity of $22.8 billion. The Company's net debt to book capitalization decreased to 12 percent as of December 31, 2021 from 14 percent as of December 31, 2020. The Company's ratio of current assets to current liabilities was 1.52:1 as of December 31, 2021, as compared to 1.36:1 as of December 31, 2020.
Debt ratings. The Company is rated as investment grade by three credit rating agencies. The Company's credit ratings are subject to regular reviews by the credit rating agencies. The Company believes that each of the rating agencies considers many factors in determining the Company's ratings, including: (i) production growth opportunities, (ii) liquidity, (iii) debt levels, (iv) asset composition and (v) proved reserve mix. A reduction in the Company's debt ratings could increase the interest rates that the Company incurs on Credit Facility borrowings and could negatively impact the Company's ability to obtain additional financing or the interest rate, fees and other terms associated with such additional financing.
Critical Accounting Estimates
The Company prepares its consolidated financial statements for inclusion in this Report in accordance with GAAP. See Note 2 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information. The following is a discussion of the Company's most critical accounting estimates, judgments and uncertainties that are inherent in the Company's application of GAAP.
Successful efforts method of accounting. The Company utilizes the successful efforts method of accounting for oil and gas producing activities as opposed to the alternate acceptable full cost method. In general, the Company believes that net assets and net income are more conservatively measured under the successful efforts method of accounting for oil and gas producing activities than under the full cost method, particularly during periods of active exploration. The critical difference between the successful efforts method of accounting and the full cost method is that under the successful efforts method, exploratory dry

65

PIONEER NATURAL RESOURCES COMPANY
holes and geological and geophysical exploration costs are charged against earnings during the periods in which they occur; whereas, under the full cost method of accounting, such costs and expenses are capitalized as assets, pooled with the costs of successful wells and charged against the earnings of future periods as a component of depletion expense.
Proved reserve estimates. Estimates of the Company's proved reserves included in this Report are prepared in accordance with GAAP and SEC guidelines. The accuracy of a proved reserve estimate is a function of:
the quality and quantity of available data;
the interpretation of that data;
the accuracy of various mandated economic assumptions; and
the judgment of the persons preparing the estimate.
The Company's proved reserve information included in this Report as of December 31, 2021, 2020 and 2019 was prepared by the Company's engineers and audited by independent petroleum engineers with respect to the Company's major properties. Estimates prepared by third parties may be higher or lower than those included herein.
Because these estimates depend on many assumptions, all of which may substantially differ from future actual results, proved reserve estimates will be different from the quantities of oil and gas that are ultimately recovered. In addition, results of drilling, testing and production after the date of an estimate may justify, positively or negatively, material revisions to the estimate of proved reserves.
It should not be assumed that the Standardized Measure included in this Report as of December 31, 2021 is the current market value of the Company's estimated proved reserves. In accordance with SEC requirements, the Company based the 2021 Standardized Measure on a twelve month average of commodity prices on the first day of each month in 2021 and prevailing costs on the date of the estimate. Actual future prices and costs may be materially higher or lower than the prices and costs utilized in the estimate. See "Item 2. Properties" and Unaudited Supplementary Information included in "Item 8. Financial Statements and Supplementary Data" for additional information.
The Company's estimates of proved reserves materially impact depletion expense. If the estimates of proved reserves decline, the rate at which the Company records depletion expense will increase, reducing future net income. Such a decline may result from lower commodity prices, which may make it uneconomical to drill for and produce higher cost fields. In addition, a decline in proved reserve estimates may impact the outcome of the Company's assessment of its proved properties and goodwill for impairment.
Impairment of proved oil and gas properties. The Company reviews its proved properties to be held and used whenever management determines that events or circumstances indicate that the recorded carrying value of the properties may not be recoverable. Management assesses whether or not an impairment provision is necessary based upon estimated future recoverable proved and risk-adjusted probable and possible reserves, commodity price outlooks, production and capital costs expected to be incurred to recover the reserves, discount rates commensurate with the nature of the properties and net cash flows that may be generated by the properties. Proved oil and gas properties are reviewed for impairment at the level at which depletion of proved properties is calculated. See Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Impairment of unproved oil and gas properties. Management assesses unproved oil and gas properties for impairment on a project-by-project basis. Such assessments are affected by the results of exploration activities, commodity price outlooks, planned future property sales or expiration of all or a portion of such projects.
Suspended wells. The Company suspends the costs of exploratory/extension wells that discover hydrocarbons pending a final determination of the commercial potential of the discovery. The ultimate disposition of these well costs is dependent on the results of future drilling activity and development decisions. If the Company decides not to pursue additional appraisal activities or development of these fields, the costs of these wells will be charged to exploration and abandonments expense.
The Company does not carry the costs of drilling an exploratory/extension well as an asset in its consolidated balance sheets following the completion of drilling unless both of the following conditions are met:
the well has found a sufficient quantity of reserves to justify its completion as a producing well; and
the Company is making sufficient progress assessing the reserves and the economic and operating viability of the project.
Due to the capital intensive nature and the geographical location of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination on its commercial viability. In these instances, the project's feasibility is not contingent upon price improvements or advances in

66

PIONEER NATURAL RESOURCES COMPANY
technology, but rather the Company's ongoing efforts and expenditures related to accurately predicting the hydrocarbon recoverability based on well information, gaining access to other companies' production, transportation or processing facilities and/or getting partner approval to drill additional appraisal wells. These activities are ongoing and being pursued constantly. Consequently, the Company's assessment of suspended exploratory/extension well costs is continuous until a decision can be made that the well has found sufficient quantities of proved reserves to sanction the project or is determined to be noncommercial and is impaired. See Note 6 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Asset retirement obligations. The Company has significant obligations to remove tangible equipment and facilities and to restore the land at the end of oil and gas production operations. The Company's removal and restoration obligations are primarily associated with plugging and abandoning wells. Estimating the future restoration and removal costs is difficult and requires management to make estimates and judgments because most of the removal obligations are many years in the future and contracts and regulations often have vague descriptions of what constitutes removal. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety and public relations considerations.
Inherent in the present value calculation are numerous assumptions and judgments including the ultimate settlement amounts, credit-adjusted discount rates, timing of settlement and changes in the legal, regulatory, environmental and political environments. To the extent future revisions to these assumptions impact the present value of the existing asset retirement obligations, a corresponding adjustment is generally made to the oil and gas property or other property and equipment balance. See Note 9 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Deferred tax asset valuation allowances. The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that its deferred tax assets can be realized prior to their expiration. Pioneer monitors Company-specific, oil and gas industry and worldwide economic factors and based on that information, along with other data, reassesses the likelihood that the Company's net operating loss carryforwards and other deferred tax attributes in the U.S. federal, state, local and foreign tax jurisdictions will be utilized prior to their expiration. There can be no assurance that facts and circumstances will not materially change and require the Company to establish deferred tax asset valuation allowances in certain jurisdictions in a future period.
Uncertain tax positions. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based upon the technical merits of the position. The Company has state unrecognized tax benefits from tax years 2013 and 2015 through 2018 ("UTBs") resulting from research and experimental expenditures related to horizontal drilling and completion innovations. If all or a portion of the UTBs is sustained upon examination by the taxing authorities, the tax benefit will be recorded as a reduction to the Company's deferred tax liability and will affect the Company's effective tax rate in the period recorded. The issues related to the claims are complex and uncertain, and the Company cannot conclude that it is more likely than not that it will sustain the claims. Accordingly, no tax benefit has been recognized for the filed claims. The Company believes it will substantially resolve the uncertainties associated with the state UTBs within the next twelve months. See Note 17 of Notes to the Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Goodwill impairment. The Company reviews its goodwill for impairment at least annually. During the third quarter of 2021, the Company performed a qualitative assessment of goodwill to assess whether it was more likely than not that the fair value of the Company's reporting unit was less than its carrying amount as a basis for determining whether it was necessary to record a noncash impairment charge. The Company determined that it was more likely than not that the Company's goodwill was not impaired. There is considerable judgment involved in estimating fair values, particularly in determining the valuation methods and the weighting to use for each method if multiple valuation methods are applied. See Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Litigation and environmental contingencies. The Company makes judgments and estimates in recording liabilities for ongoing litigation and environmental remediation. Actual costs can vary from such estimates for a variety of reasons. The costs to settle litigation can vary from estimates based on differing interpretations of laws and opinions and assessments on the amount of damages. Similarly, environmental remediation liabilities are subject to change because of changes in laws and regulations, developing information relating to the extent and nature of site contamination and improvements in technology. A liability is recorded for these types of contingencies if the Company determines the loss to be both probable and reasonably estimable. See Note 11 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

PIONEER NATURAL RESOURCES COMPANY
Valuation of stock-based compensation. The Company calculates the fair value of stock-based compensation using various valuation methods. The valuation methods require the use of estimates to derive the inputs necessary to determine fair value. The Company utilizes (i) the Black-Scholes option pricing model to measure the fair value of stock options, (ii) the closing stock price on the day prior to the date of grant for the fair value of restricted stock awards, (iii) the closing stock price on the balance sheet date for restricted stock awards that are expected to be settled wholly or partially in cash on their vesting date and (iv) the Monte Carlo simulation method for the fair value of performance unit awards. See Note 8 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Valuation of other assets and liabilities at fair value. The Company periodically measures and records certain assets and liabilities at fair value. The assets and liabilities that the Company measures and records at fair value on a recurring basis include equity investments, deferred compensation plan assets, commodity derivative contracts, marketing derivative contracts and interest rate contracts. Other assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. The assets and liabilities that the Company measures and records at fair value on a nonrecurring basis can include inventories, proved and unproved oil and gas properties, assets acquired and liabilities assumed in business combinations, goodwill and other long-lived assets that are written down to fair value when they are determined to be impaired or held for sale. The Company also measures and discloses certain financial assets and liabilities at fair value, such as long-term debt. The valuation methods used by the Company to measure the fair values of these assets and liabilities may require considerable management judgment and estimates to derive the inputs necessary to determine fair value estimates, such as future prices, credit-adjusted risk-free rates and current volatility factors. See Note 4 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
In the normal course of business, the Company's financial position is routinely subject to a variety of risks, including market risks associated with changes in commodity prices, interest rate movements on outstanding debt and credit risks. The following quantitative and qualitative information is provided about financial instruments to which the Company was a party as of December 31, 2021, and from which the Company may incur future gains or losses from changes in commodity prices or interest rates. The Company does not enter into any financial instruments, including derivatives, for speculative or trading purposes.
Interest rate risk. As of December 31, 2021, the Company had no variable rate debt outstanding under the Credit Facility and, consequently, no related exposure to interest rate risk. As of December 31, 2021, the Company had $6.9 billion of fixed rate long-term debt outstanding with a weighted average cash interest rate of 1.9 percent. Although changes in interest rates may affect the fair value of the Company's fixed rate long-term debt, any changes would not expose the Company to the risk of earnings or cash flow losses. The Company has no interest rate derivative instruments outstanding; however, it may enter into derivative instruments in the future to mitigate interest rate risk. See Note 4 and Note 7 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.
Commodity price risk. The Company's primary market risk exposure is related to the price it receives from the sale of its oil, NGL and gas production. Realized pricing is volatile and is determined by market prices that fluctuate with changes in supply and demand for these products throughout the world. The price the Company receives for its production depends on many factors outside of the control of the Company, including differences in commodity pricing at the point of sale versus market index prices. Reducing the Company's exposure to price volatility helps secure funds to be used in its capital program and to fund general working capital needs, debt obligations, dividends and share repurchases, among other uses. The Company mitigates its commodity price risk by (i) maintaining financial flexibility with a strong balance sheet, (ii) using derivative financial instruments and (iii) sales of purchased oil and gas.
Derivative financial instruments. The Company's decision on the quantity and price at which it executes derivative contracts is based in part on its view of current and future market conditions. The Company may choose not to enter into derivative positions for expected production if the commodity price forecast for certain time periods is deemed to be unfavorable. Additionally, the Company may choose to liquidate existing derivative positions prior to the expiration of their contractual maturity in order to monetize gain positions or minimize loss positions if it is anticipated that the commodity price forecast is expected to improve. Proceeds, if any, can be used for the purpose of funding the Company's capital program, general working capital needs, debt obligations, dividends and share repurchases, among other uses. While derivative positions limit the downside risk of adverse price movements, they also limit future revenues from upward price movements. The Company manages commodity price risk with the following types of commodity derivative contracts:
Swaps. The Company receives a fixed price and pays a floating market price to the counterparty on a notional amount of sales volumes, thereby fixing the price for the commodity sold.
Collars. Collar contracts provide minimum ("floor" or "long put") and maximum ("ceiling") prices on a notional amount of sales volumes, thereby allowing some price participation if the relevant index price closes above the floor price but below the ceiling price.
Collar contracts with short put options. Collar contracts with short put options differ from other collar contracts by virtue of the short put option price, below which the Company's realized price will exceed the variable market prices by the long put-to-short put price differential.
Basis swaps. Basis swap contracts fix the basis differentials between the index price at which the Company sells its production and the index price used in swap or collar contracts.
Rollfactor swaps. Rollfactor swaps are utilized to match the derivative contracts to the physical oil sales. Physical oil sales typically use trade month averages whereas derivative contracts utilize calendar month averages. The rollfactor swaps convert the calendar month into a trade month.
Options. Selling individual call options can enhance the market price by the premium received or, alternatively, the premium received can be utilized to improve swap or collar contract prices. Purchased put options establish a minimum floor price (less any premiums paid) and allows participation in higher prices when prices close above the floor price.
The Company has entered into commodity derivative contracts for a portion of its forecasted 2022 production; consequently, if commodity prices decline, the Company could realize lower prices for volumes not protected by the

69

PIONEER NATURAL RESOURCES COMPANY
Company's derivative activities and could see a reduction in quoted derivative contract prices on additional volumes in the future. As a result, the Company's internal cash flows will be negatively impacted by a reduction in commodity prices.

See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for a description of the Company's open derivative positions and additional information.
Sales of purchased commodities. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets, and to satisfy unused gas pipeline capacity commitments. The Company also enters into pipeline capacity commitments to secure diesel supply from the Gulf Coast to the Company's operations in the Permian Basin. The Company periodically enters into separate sales transactions with third parties related to diesel volumes that exceed the Company's operational needs.
Marketing derivatives. The Company's marketing derivatives reflect two long-term marketing contracts that were entered in October 2019 whereby the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that began on January 1, 2021 and ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland oil price and the price the Company receives for the oil volumes sold is a weighted average sales price ("WASP") that a non-affiliated counterparty receives for selling oil through a Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the marketing contracts, the Company determined that the marketing contracts should be accounted for as derivative instruments. Similar to sales of purchased commodities, marketing

derivatives allow the Company to diversify a portion of its oil sales from its area of production to Gulf Coast and international markets.

Credit risk. The Company's primary concentration of credit risks are associated with the collection of receivables resulting from the sale of oil and gas production and purchased oil and gas, and the risk of a counterparty's failure to meet its obligations under derivative contracts with the Company.
The Company's commodities are sold to various purchasers who must be prequalified under the Company's credit risk policies and procedures. The Company monitors exposure to counterparties primarily by reviewing credit ratings, financial criteria and payment history. Where appropriate, the Company obtains assurances of payment, such as a guarantee by the parent company of the counterparty, a letter of credit or other credit support. Historically, the Company's credit losses on commodity receivables have not been material.
The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures.
The Company has entered into International Swap Dealers Association Master Agreements ("ISDA Agreements") with each of its commodity derivative counterparties. The terms of the ISDA Agreements provide the Company and the counterparties with right of set off upon the occurrence of defined acts of default by either the Company or a counterparty to a derivative contract, whereby the party not in default may set off all derivative liabilities owed to the defaulting party against all derivative asset receivables from the defaulting party. See Note 5 of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" for additional information.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and the Board of Directors of Pioneer Natural Resources Company
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Pioneer Natural Resources Company (the Company) as of December 31, 2021 and 2020, the related consolidated statements of operations, equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 22, 2022 expressed an unqualified opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Depreciation, Depletion and Amortization of Proved Oil and Gas Properties
Description of the Matter
At December 31, 2021, the net book value of the Company's proved oil and gas properties was $22,119 million, and depreciation, depletion and amortization (DD&A) expense was $2,498 million for the year then ended. As described in Note 2, under the successful efforts method of accounting, capitalized costs of proved properties are depleted using the units-of-production method based on proved reserves, as estimated by the Company's engineers. Proved oil and gas reserve estimates are based on geological and engineering interpretation and judgment. Significant judgment is required by the Company's engineers in evaluating geological and engineering data when estimating proved oil and gas reserves. Estimating reserves also requires the selection of inputs, including oil and gas price assumptions, future operating and capital cost assumptions and tax rates by jurisdiction, among others. Because of the complexity involved in estimating oil and gas reserves, management used independent petroleum engineers to audit the estimates prepared by the Company's engineers as of December 31, 2021.

Auditing the Company's DD&A calculation is especially complex because of the use of the work of the Company's engineers and the independent petroleum engineers and the evaluation of management's determination of the inputs described above used by the engineers in estimating proved oil and gas reserves.

73

How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of the Company's controls over its process to calculate DD&A, including management's controls over the completeness and accuracy of the financial data provided to the engineers for use in estimating proved oil and gas reserves.

Our audit procedures included, among others, evaluating the professional qualifications and objectivity of the Company's engineers responsible for the preparation of the reserve estimates and the independent petroleum engineers used to audit the estimates. In addition, in assessing whether we can use the work of the engineers we evaluated the completeness and accuracy of the financial data and inputs described above used by the engineers in estimating proved oil and gas reserves by agreeing them to source documentation and we identified and evaluated corroborative and contrary evidence. For proved undeveloped reserves, we evaluated management's development plan for compliance with SEC requirements. We also tested the mathematical accuracy of the DD&A calculations, including comparing the proved oil and gas reserves amounts used to the Company's reserve report.
Accounting for Acquisitions
Description of the Matter
During 2021, the Company completed its acquisitions of Parsley Energy, Inc. ("Parsley") and Double Eagle III Midco I LLC ("DoublePoint") for net consideration of $6,883 million and $5,234 million, respectively, as disclosed in Note 3 to the consolidated financial statements. The transactions were accounted for as business combinations.

Auditing the Company's accounting for its acquisitions of Parsley and DoublePoint was complex due to the significant estimation required by management to determine the fair value of proved and unproved properties. The significant estimation was primarily due to selection of key inputs into the valuation model. The Company used a combination of income and market approaches. The significant assumptions used in the income approach to value proved properties included development and production profiles, price, and discount rates. These significant assumptions are forward looking and could be affected by future economic and market conditions. The market approach used to value unproved properties required the identification and evaluation of comparable transactions.
How We Addressed the Matter in Our Audit
We tested the Company's controls over its accounting for acquisitions. For example, we tested controls over the recognition and measurement of proved and unproved properties, including the valuation models and underlying assumptions used to develop such estimates.

To test the estimated fair values, we performed audit procedures that included, among others, evaluating the Company's use of the income approach and testing the significant assumptions used in the models, including the completeness and accuracy of the underlying data. Our audit procedures also included evaluating the professional qualifications and objectivity of the Company's engineers responsible for the preparation of the reserve estimates and the independent petroleum engineers used to audit the estimates. In addition, in assessing whether we can use the work of the engineers, we evaluated the completeness and accuracy of the financial data and inputs described above used by the engineers in estimating proved oil and gas reserves by agreeing them to source documentation and we identified and evaluated corroborative and contrary evidence. We involved our valuation specialists to assist in our evaluation of the significant assumptions, including the evaluation of price and discount rates used in the income approach and the comparable transactions used in the market approach.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2021, 2020 and 2019


NOTE 1. Organization and Nature of Operations
Pioneer is a Delaware corporation whose common stock is listed and traded on the NYSE. The Company is a large independent oil and gas exploration and production company that explores for, develops and produces oil, NGLs and gas in the Midland Basin in West Texas.
Impact of the COVID-19 Pandemic. The COVID-19 pandemic resulted in a severe worldwide economic downturn, significantly disrupting the demand for oil, throughout the world, and created significant volatility, uncertainty and turmoil in the oil and gas industry. The decrease in demand for oil combined with pressures on the global supply-demand balance for oil and related products, resulted in oil prices declining significantly beginning in late February 2020. Since mid-2020, oil prices improved, with demand steadily increasing despite the uncertainties surrounding the COVID-19 variants, which have continued to inhibit a full global demand recovery. In addition, worldwide oil inventories are, from a historical perspective, very low and supply increases from OPEC, Russia and other oil producing nations are not expected to be sufficient to meet forecasted oil demand growth in 2022 and 2023, with many OPEC countries not able to produce at their OPEC agreed upon quota levels due to their lack of capital investments over the past few years in developing incremental oil supplies. Global oil price levels will ultimately depend on various factors and consequences beyond the Company's control, such as (i) the effectiveness of responses to combat the COVID-19 virus and their impact on domestic and worldwide demand, (ii) the ability of OPEC, Russia and other oil producing nations to manage the global oil supply, (iii) the timing and supply impact of any Iranian sanction relief on Iran's ability to export oil, (iv) additional actions by businesses and governments in response to the pandemic, (v) the global supply chain constraints associated with manufacturing delays, and (vi) political stability of oil consuming countries.
The Company continues to assess the impact of the COVID-19 pandemic on the Company and may modify its response as the impact of COVID-19 continues to evolve.
NOTE 2. Summary of Significant Accounting Policies
Principles of consolidation. The consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries since their acquisition or formation. All material intercompany balances and transactions have been eliminated.
Use of estimates in the preparation of financial statements. Preparation of the Company's consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Depletion of oil and gas properties is determined using estimates of proved oil and gas reserves. There are numerous uncertainties inherent in the estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development expenditures. Similarly, evaluations for impairment of proved and unproved oil and gas properties are subject to numerous uncertainties including, among others, estimates of future recoverable reserves, commodity price outlooks and prevailing market rates of other sources of income and costs. Actual results could differ from the estimates and assumptions utilized.
Cash and cash equivalents. The Company's cash and cash equivalents include depository accounts held by banks and marketable securities (including commercial paper and time deposits) with original issuance maturities of 90 days or less.
Restricted cash. The Company's restricted cash includes funds held in escrow to cover future deficiency fee payments in connection with the Company's 2019 sale of its Eagle Ford assets and other remaining assets in South Texas (the "South Texas Divestiture"). Beginning in 2021, the required escrow balance declines and, to the extent there is any remaining balance after the payment of deficiency fees, the balance will become unrestricted and revert to the Company on March 31, 2023. Interest income related to restricted cash is recorded in interest and other income in the consolidated statements of operations.
Accounts receivable, net. The Company's net accounts receivable balance is primarily comprised of oil and gas sales receivables, joint interest receivables, accounts receivable due from affiliates and other receivables for which the Company does not require collateral security. The Company's share of oil and gas production is sold to various purchasers who must be prequalified under the Company's credit risk policies and procedures. The Company records allowances for doubtful accounts based on historical collection experience, current and future economic and market conditions, the length of time that the accounts receivables have been outstanding and the financial condition of its purchasers. The Company's credit risk related to collecting accounts receivables is mitigated by using credit and other financial criteria to evaluate the credit standing of the

December 31, 2021, 2020 and 2019
entity obligated to make payment on the accounts receivable, and where appropriate, the Company obtains assurances of payment, such as a guarantee by the parent company of the counterparty, letters of credit or other credit support.
The Company considers forward-looking information to estimate expected credit losses. The Company establishes allowances for bad debts equal to the estimable portions of accounts receivable for which failure to collect is expected to occur. The Company estimates uncollectible amounts for joint interest receivables based on the length of time that the accounts receivables have been outstanding, historical collection experience and current and future economic and market conditions. Allowances for doubtful accounts are recorded as reductions to the carrying values of the receivables included in the Company's consolidated balance sheets and are recorded in other expense in the consolidated statements of operations in the accounting periods during which failure to collect an estimable portion is determined to be probable. The Company's allowance for doubtful accounts totaled $9 million and $3 million as of December 31, 2021 and 2020, respectively.
Inventories. The Company's inventories consist of materials, supplies and commodities. The Company's materials and supplies inventory is primarily comprised of oil and gas maintenance materials and repair parts, water and other operating supplies. The materials and supplies inventory is primarily acquired for use in future drilling and production operations or repair operations and is carried at the lower of cost or market, on a weighted average cost basis. Valuation allowances for materials and supplies inventories are recorded as reductions to the carrying values of the materials and supplies inventories included in the Company's consolidated balance sheets and as charges in other expense in the consolidated statements of operations.
Commodity inventories are carried at the lower of cost or market, on a first-in, first-out basis. The Company's commodity inventories consist of oil, NGLs, gas and diesel volumes held in storage or as linefill in pipelines. Any valuation allowances of commodity inventories are recorded as reductions to the carrying values of the commodity inventories included in the Company's consolidated balance sheets and as charges to other expense in the consolidated statements of operations.
The components of inventories are as follows:

Investment in affiliate. In December 2018, the Company completed the sale of its pressure pumping assets to ProPetro Holding Corp. ("ProPetro") in exchange for $110 million of cash and 16.6 million shares of ProPetro's common stock, representing an ownership interest in ProPetro of 16 percent. Additionally, in October 2019, Phillip A. Gobe, a nonemployee member of the Company's board of directors, was appointed by the board of directors of ProPetro to serve as its Executive Chairman, and in March 2020 he was appointed as Chief Executive Officer and Chairman of the board of directors. On August 31, 2021, Mr. Gobe transitioned from ProPetro's Chairman and Chief Executive Officer to its Executive Chairman. Mark S. Berg, the Company's Executive Vice President, Corporate Operations, serves as a member of the ProPetro board of directors under the Company's right to designate a director to the board of directors of ProPetro so long as the Company owns five percent or more of ProPetro's outstanding common stock. Based on the Company's ownership in ProPetro and representation on the ProPetro board of directors, ProPetro is considered an affiliate and deemed to be a related party. The Company uses the fair value option to account for its equity method investment in ProPetro with any changes in fair value recorded in interest and other income (loss) in the consolidated statements of operations. The carrying value of the Company's investment in ProPetro is included in investment in affiliate in the consolidated balance sheets. See Note 4, Note 12 and Note 15 for additional information.
Short-term investment. In October 2021, the Company completed the sale of approximately 20,000 net acres in western Glasscock County (the "Glasscock Divestiture") to Laredo Petroleum, Inc. ("Laredo") in exchange for $137 million in cash and 960 thousand shares of Laredo's common stock. The Laredo common stock held by the Company is treated as an investment in equity securities with changes in fair value recorded in interest and other income (loss) in the consolidated statements of operations. The carrying value of the Laredo common stock held by the Company is included in short-term investments in the consolidated balance sheets. See Note 4 and Note 15 for additional information.

December 31, 2021, 2020 and 2019
Oil and gas properties. The Company utilizes the successful efforts method of accounting for its oil and gas properties. Under this method, all costs associated with productive wells and nonproductive development wells are capitalized while nonproductive exploration costs and geological and geophysical expenditures are expensed.
The Company does not carry the costs of drilling an exploratory well as an asset in its consolidated balance sheets following the completion of drilling unless both of the following conditions are met: (i) the well has found a sufficient quantity of reserves to justify its completion as a producing well and (ii) the Company is making sufficient progress assessing the reserves and the economic and operating viability of the project. The Company's exploratory wells include extension wells that extend the limits of a known reservoir.
Due to the capital-intensive nature and the geographical location of certain projects, it may take an extended period of time to evaluate the future potential of an exploration project and the economics associated with making a determination on its commercial viability. In these instances, the project's feasibility is not contingent upon price improvements or advances in technology, but rather the Company's ongoing efforts and expenditures related to accurately predicting the hydrocarbon recoverability based on well information, gaining access to other companies' production data in the area, transportation or processing facilities, and/or getting partner approval to drill additional appraisal wells. These activities are ongoing and are being pursued constantly. Consequently, the Company's assessment of suspended exploratory well costs is continuous until a decision can be made that the project has found sufficient proved reserves to sanction the project or is noncommercial and is charged to exploration and abandonments expense. See Note 6 for additional information.
As of December 31, 2021, the Company owned a participating interest in 11 gas processing plants, including the related gathering systems. The Company's ownership interests in the gas processing plants are primarily to accommodate handling the Company's gas production and thus are considered a component of the capital and operating costs of the respective fields that the plants service. The operator's of the plants process the Company's and third-party gas volumes for a fee. The Company's share of revenues and expenses derived from volumes processed through the plants are reported as components of oil and gas production costs. Revenues generated from the plants for the years ended December 31, 2021, 2020 and 2019 were $271 million, $178 million and $140 million, respectively. Expenses attributable to the plants for the same respective periods were $61 million, $76 million and $65 million. The capitalized costs of the plants are included in proved oil and gas properties and are depleted using the unit-of-production method along with the other capitalized costs of the field that they service.
The capitalized costs of proved properties are depleted using the unit-of-production method based on proved reserves. Costs of significant nonproducing properties, wells in the process of being drilled and in-process development projects are excluded from depletion until the related project is completed and proved reserves are established or, if unsuccessful, abandonments expense is recognized.
Proceeds from the sales of individual properties and the capitalized costs of individual properties sold or abandoned are credited and charged, respectively, to accumulated depletion, depreciation and amortization, if doing so does not materially impact the depletion rate of an amortization base. Generally, no gain or loss is recorded until an entire amortization base is sold. However, gain or loss is recorded from the sale of less than an entire amortization base if the disposition is significant enough to materially impact the depletion rate of the remaining properties in the amortization base.
The Company performs assessments of its long-lived assets to be held and used, including proved oil and gas properties accounted for under the successful efforts method of accounting, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future cash flows, including cash flows from the Company's water services business that are used in the development of the assets, is less than the carrying amount of the assets, including the carrying value of the Company's water services business. In these circumstances, the Company recognizes an impairment charge for the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. See Note 4 for additional information.
Oil and gas leasehold acquisition costs are capitalized when incurred and included as unproved oil and gas properties in the consolidated balance sheets. Unproved oil and gas properties are periodically assessed for impairment on a project-by-project basis. These impairment assessments are affected by the results of exploration activities, commodity price outlooks, planned future property sales or expiration of all or a portion of such projects. If the Company's assessment determines that a project is not expected to be developed or is unlikely to recover its costs, the Company will recognize an impairment charge at that time. Impairment charges for unproved oil and gas properties are recorded in exploration and abandonments in the consolidated statements of operations.

____________________
(a)Includes land, buildings, any related improvements to land and buildings, and a finance lease entered into by the Company for its corporate headquarters in Irving, Texas. See Note 10 for additional information.
(b)Includes costs for pipeline infrastructure and water supply wells.
(c)Includes capitalized costs and capitalized interest on other property and equipment not yet placed in service.
(d)Includes vehicles and well servicing equipment, including pulling units, fracture stimulation tanks, water transport trucks, hot oilers, construction equipment and fishing tools, used on Company-operated properties. The Company sold its well servicing equipment in March 2021.
Other property and equipment is depreciated over its estimated useful life on a straight-line basis. Buildings are generally depreciated over 20 to 39 years. Water infrastructure is generally depreciated over three to 50 years, excluding capitalized costs related to the Company's effluent water contract associated with the City of Midland's water treatment facility, which are depleted on a units-of-production basis. Equipment, vehicles, furniture and fixtures and information technology assets are generally depreciated over three to 10 years. Sand reserves are depleted on a units-of-production basis.
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such assets are considered to be impaired, the impairment to be recorded is measured by the amount by which the carrying amount of the asset exceeds its estimated fair value. The estimated fair value is determined using either a discounted future cash flow model or another appropriate fair value method.
Leases. The Company enters into leases for drilling rigs, storage tanks, equipment and buildings and recognizes lease expense on a straight-line basis over the lease term. Lease right-of-use assets and liabilities are initially recorded on the lease commencement date based on the present value of lease payments over the lease term. As most of the Company's lease contracts do not provide an implicit discount rate, the Company uses its incremental borrowing rate, which is determined based on information available at the commencement date of a lease. Leases may include renewal, purchase or termination options that can extend or shorten the term of the lease. The exercise of those options is at the Company's sole discretion and is evaluated at inception and throughout the contract to determine if a modification of the lease term is required. Leases with an initial term of 12 months or less are not recorded as a lease right-of-use asset and liability. See Note 10 for additional information.
Goodwill. Goodwill is assessed for impairment whenever it is more likely than not that events or circumstances indicate the carrying value of a reporting unit exceeds its fair value, but no less often than annually. An impairment charge is recorded for the amount by which the carrying amount exceeds the fair value of a reporting unit in the period it is determined to be impaired.
The Company performed its annual qualitative assessment of goodwill during the third quarter of 2021 to determine whether it was more likely than not that the fair value of the Company's reporting unit was less than its carrying amount. Based on the results of the assessment, the Company determined it was not likely that the carrying value of the Company's reporting unit exceeded its fair value. See Note 4 for additional information.

Capitalized interest. The Company capitalizes interest from external borrowings on expenditures for significant development projects with an expected construction period of one year or longer until such projects are ready for their intended use. Capitalized interest is added to the cost of the underlying asset and is amortized over the useful lives of the assets in the same manner as the underlying assets.
Asset retirement obligations. The Company records a liability for the fair value of an asset retirement obligation in the period in which the associated asset is acquired or placed into service, if a reasonable estimate of fair value can be made. Fair value is determined using a present value approach, incorporating assumptions about estimated amounts and timing of settlements. Asset retirement obligations are generally capitalized as part of the carrying value of the long-lived asset to which it relates. Conditional asset retirement obligations that meet the definition of liabilities are recorded when incurred and when fair value can be reasonably estimated.
The Company includes the current and noncurrent portions of asset retirement obligations in other current liabilities and other liabilities, respectively, in the consolidated balance sheets and expenditures are included as cash used in operating activities in the consolidated statements of cash flows. See Note 9 for additional information.
Treasury stock. Treasury stock purchases are recorded at cost. Upon reissuance, the cost of treasury shares held is reduced by the average purchase price per share of the aggregate treasury shares held.
Revenue recognition. The Company recognizes revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.
Oil sales. Sales under the Company's oil contracts are generally considered performed when the Company sells oil production at the wellhead and receives an agreed-upon index price, net of any price differentials. The Company recognizes the sales revenue when (i) control/custody transfers to the purchaser at the wellhead and (ii) the net price is fixed and determinable. Any costs incurred prior to the transfer of control to the customer, such as gathering and transportation costs, are recognized as oil and gas production costs.
NGL and gas sales. Under the majority of the Company's gas processing contracts, gas is delivered to a midstream processing entity and the Company elects to take residue gas and NGLs in-kind at the tailgate of the gas processing plant. The Company recognizes revenue when the products are delivered (custody transfer) to the ultimate third-party purchaser at a contractually agreed-upon delivery point at a specified index price, with gathering and processing fees recognized as oil and gas production costs.
Sales of purchased commodities. The Company enters into pipeline capacity commitments in order to secure available oil, NGLs and gas transportation capacity from the Company's areas of production and secure diesel supply from the Gulf Coast to the Company's operations in the Permian Basin. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets, and to satisfy unused gas pipeline capacity commitments. Revenues and expenses from these transactions are generally presented on a gross basis in sales of purchased commodities and purchased commodities expense in the accompanying consolidated statements of operations as the Company acts as a principal in the transaction by assuming both the risks and rewards of ownership, including credit risk, of the commodities purchased and the responsibility to deliver the commodities sold. In conjunction with the Company's downstream sales, the Company also enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production to downstream sales points. The transportation costs associated with these transactions are included in purchased commodities expense.
See Note 14 for additional information.
Derivatives. All of the Company's derivatives are accounted for as non-hedge derivatives and are recorded at estimated fair value in the consolidated balance sheets. All changes in the fair values of its derivative contracts are recorded as gains or losses in the earnings of the periods in which they occur. The Company periodically enters into commodity price derivative positions, including oil production derivatives, NGL production derivatives and gas production derivatives. From time to time, the Company enters into contracts that contain embedded derivatives. These contracts are reviewed when they are entered into in order to identify and account for the derivative components. The Company's marketing derivatives and derivative associated with contingent consideration were deemed derivatives embedded in host contracts.

The Company enters into derivatives under master netting arrangements, which, in an event of default, allows the Company to offset payables to and receivables from the defaulting counterparty. The Company classifies the fair value amounts of derivative assets and liabilities executed under master netting arrangements as net current or noncurrent other assets or net current or noncurrent derivative liabilities, whichever the case may be, by instrument type and counterparty.
The Company has entered into International Swap Dealers Association Master Agreements ("ISDA Agreements") with each of its commodity price derivative counterparties. The terms of the ISDA Agreements provide the Company and the counterparties with rights of set off upon the occurrence of defined acts of default by either the Company or a counterparty to a derivative, whereby the party not in default may set off all derivative liabilities owed to the defaulting party against all derivative asset receivables from the defaulting party. See Note 5 for additional information.
Income taxes. The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and net operating loss and tax credit carryforwards. The amount of deferred taxes on these temporary differences is determined using the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, as applicable, based on tax rates and laws in the respective tax jurisdiction enacted as of the balance sheet date.
The Company reviews its deferred tax assets for recoverability and establishes a valuation allowance based on projected future taxable income, applicable tax strategies and the expected timing of the reversals of existing temporary differences. A valuation allowance is provided when it is more likely than not (likelihood of greater than 50 percent) that some portion or all of the deferred tax assets will not be realized.
The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based upon the technical merits of the position. If all or a portion of the unrecognized tax benefit is sustained upon examination by the taxing authorities, the tax benefit will be recognized as a reduction to the Company's deferred tax liability and will affect the Company's effective tax rate in the period it is recognized. See Note 17 for additional information.
The Company records any tax-related interest charges as interest expense and any tax-related penalties as other expense in the consolidated statements of operations.
Stock-based compensation. Stock-based compensation expense for restricted stock, restricted stock units and performance units expected to be settled in the Company's common stock ("Equity Awards") is measured at the grant date or modification date, as applicable, using the fair value of the award, and is recorded, net of estimated forfeitures, on a straight line basis over the requisite service period of the respective award. The fair value of Equity Awards, except performance unit awards, is determined on the grant date or modification date, as applicable, using the prior day's closing stock price. The fair value of performance unit awards is determined using the Monte Carlo simulation model.
Equity Awards are net settled by withholding shares of the Company's common stock to satisfy income tax withholding payments due upon vesting. Remaining vested shares are remitted to individual employee brokerage accounts. Shares to be delivered upon vesting of Equity Awards are made available from authorized, but unissued shares or shares held as treasury stock.
Restricted stock awards expected to be settled in cash on their vesting dates, rather than in common stock ("Liability Awards"), are included in accounts payable – due to affiliates in the consolidated balance sheets. The fair value of Liability Awards on the grant date is determined using the prior day's closing stock price. The Company recognizes the value of Liability Awards on a straight line basis over the requisite service period of the award. Liability Awards are marked to fair value as of each balance sheet date using the closing stock price on the balance sheet date. Changes in the fair value of Liability Awards are recorded as increases or decreases to stock-based compensation expense.
Equity Awards and Liability Awards participate in dividends during vesting periods and generally vest over three years.
See Note 8 for additional information.
Net income (loss) per share. The Company's basic net income per share attributable to common stockholders is computed as (i) net income attributable to common stockholders, (ii) less participating share- and unit-based basic earnings (iii) divided by weighted average basic shares outstanding. The Company's diluted net income per share attributable to common

stockholders is computed as (i) basic net income attributable to common stockholders, (ii) plus diluted adjustments to participating undistributed earnings, (iii) plus interest expense (net of income tax) associated with the Company's convertible senior notes (iv) divided by weighted average diluted shares outstanding, which assumes the Company's convertible senior notes were converted using shares of the Company's common stock at the beginning of the reporting period. Diluted net income per share attributable to common stockholders is calculated under both the two-class method and the treasury stock method and the more dilutive of the two calculations is presented. During periods in which the Company realizes a net loss attributable to common stockholders, securities or other contracts to issue common stock would be antidilutive to loss per share; therefore, conversion into common stock is assumed not to occur. See Note 18 for additional information.
Segments. Based upon how the Company is organized and managed, the Company has one reportable operating segment, which is oil and gas development, exploration and production. The Company considers its water services business and sales of purchased commodities as ancillary to its oil and gas development, exploration and producing activities and manages them to support such activities. In addition, the Company has a single, company-wide management team that allocates capital resources to maximize profitability and measures financial performance as a single enterprise.
Adoption of new accounting standards. In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, "Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity" ("ASU 2020-06"). ASU 2020-06 simplifies the accounting for certain convertible instruments by removing the separation models for convertible debt with a cash conversion feature or convertible instruments with a beneficial conversion feature. Additionally, ASU 2020-06 amends the diluted earnings per share calculation for convertible instruments by requiring the use of the if-converted method. The if-converted method assumes the conversion of convertible instruments occurs at the beginning of the reporting period and diluted weighted average shares outstanding includes the common shares issuable upon conversion of the convertible instruments. The Company early adopted ASU 2020-06 on January 1, 2021.
Upon issuance of the Company's $1.3 billion principal amount of 0.250% convertible senior notes due 2025 (the "Convertible Notes") in May 2020, the Company bifurcated the debt and equity components of the Convertible Notes to long-term debt and additional paid-in capital in its consolidated balance sheet. The amount recorded to additional paid-in capital represented a debt discount that was being amortized to interest expense over the life of the Convertible Notes. As part of the adoption of ASU 2020-06, the Company (i) reversed the debt discount and related deferred income tax liability recorded to additional paid-in capital of $230 million and $50 million, respectively, (ii) recorded a cumulative effect of the adoption of ASU 2020-06 of $22 million to retained earnings, representing a reversal of $28 million of the debt discount that was amortized to interest expense, net of an associated deferred income tax impact of $6 million, in 2020 and (iii) recorded the respective offsets for items (i) and (ii) above, representing the unamortized debt discount attributable to the Convertible Notes of $202 million to long-term debt and the associated deferred tax impact of $44 million to deferred income tax liabilities. See Note 7 for additional information.
Additionally, upon adoption of ASU 2020-06, the treasury stock method utilized by the Company to calculate earnings per share through December 31, 2020 is no longer allowed. Accordingly, the Company has transitioned to the if-converted method utilizing the modified retrospective approach, resulting in 12 million incremental shares being included in the Company's weighted-average diluted shares outstanding for the year ended December 31, 2021. See Note 18 for additional information.
NOTE 3. Acquisitions, Divestitures, Decommissioning and Restructuring Activities
Acquisitions. The Company regularly seeks to acquire or trade acreage that complements its operations, provides exploration and development opportunities, increases the lateral length of future horizontal wells and provides superior returns on investment.
DoublePoint acquisition. On May 4, 2021, the Company acquired Double Eagle III Midco 1 LLC ("DoublePoint") pursuant to a definitive membership interest purchase agreement to acquire DoublePoint dated April 1, 2021 (the "DoublePoint Acquisition") in exchange for 27 million shares of Pioneer common stock and $1.0 billion of cash. The Pioneer stock consideration transferred had a fair value of $4.2 billion.
Parsley acquisition. On January 12, 2021, the Company acquired Parsley Energy, Inc., a Delaware corporation that previously traded on the NYSE under the symbol "PE" ("Parsley"), pursuant to the Agreement and Plan of Merger, dated as of

December 31, 2021, 2020 and 2019
October 20, 2020, among Pioneer, certain of its subsidiaries, Parsley and Parsley's subsidiary, Parsley Energy, LLC (the "Parsley Acquisition"). On the closing date of the Parsley Acquisition, Parsley merged into a newly formed wholly-owned subsidiary of the Company, and the subsidiaries of Parsley, including Jagged Peak Energy LLC ("Jagged Peak"), became indirect subsidiaries of the Company.
As part of the Parsley Acquisition, each eligible share of Parsley Class A common stock and each membership interest unit of Parsley Energy, LLC were automatically converted into the right to receive 0.1252 (the "Exchange Ratio") shares of Pioneer common stock. As a result, the Company issued 52 million shares of Pioneer common stock upon the consummation of the Parsley Acquisition, representing total stock consideration transferred of approximately $6.9 billion.
Both the Parsley Acquisition and the DoublePoint Acquisition were accounted for using the acquisition method under ASC Topic 805, Business Combinations, which requires all assets acquired and liabilities assumed to be recorded at fair value at the acquisition date. Provisional fair value measurements were made for acquired assets and liabilities, and adjustments to those measurements may be made in subsequent periods (up to one year from the acquisition date) as information necessary to complete the fair value analysis is obtained.
The provisional fair values assigned to assets acquired and liabilities assumed are as follows:

Other acquisitions. During 2021, 2020 and 2019, the Company spent a total of $58 million, $14 million and $28 million, respectively, to acquire primarily undeveloped acreage for future exploration activities in the Spraberry/Wolfcamp field of the Midland Basin.
Divestitures. The Company regularly reviews its asset base to identify nonstrategic assets, the disposition of which would increase capital resources available for other activities, create organizational and operational efficiencies and further the Company's objective of maintaining a strong balance sheet to ensure financial flexibility.
The Company's notable divestitures to unaffiliated third parties are as follows:
In December 2021, the Company completed the sale of its assets in the Delaware Basin (the "Delaware Divestiture") to Continental Resources, Inc. ("Continental") for cash proceeds of $3.1 billion, after normal closing adjustments. The Company recognized a pretax loss of $1.1 billion, which is reflected in net gain (loss) on disposition of assets in the consolidated statements of operations for the year ended December 31, 2021. See Note 11 for additional information.
In October 2021, the Company completed the sale of approximately 20,000 net acres in western Glasscock County of the Permian Basin to Laredo in exchange for $137 million in cash and 960 thousand shares of Laredo's common stock, representing total consideration transferred of $206 million, after normal closing adjustments. The sale of these assets resulted in a pretax gain of $1 million, which is reflected in net gain (loss) on disposition of assets in the consolidated statements of operations for the year ended December 31, 2021. The Laredo common stock held by the Company as a result of the divestiture is included in short-term investments in the consolidated balance sheet as of December 31, 2021. See Note 4 and Note 15 for additional information.
In March 2021, the Company sold its well services business (the "Well Services Divestiture") to a third party for (i) net cash proceeds of $20 million and (ii) up to $4 million of additional cash proceeds to be earned over the next three years. The Company recorded a gain on sale of $9 million, which is reflected in net gain (loss) on disposition of assets in the consolidated statements of operations for the year ended December 31, 2021.
In May 2020, the Company completed the sale of certain vertical wells and approximately 1,500 undeveloped acres in Upton County of the Permian Basin for net cash proceeds of $6 million. The Company recorded a gain of $6 million associated with the sale.
During 2019 the Company completed multiple sales of certain vertical and horizontal wells as well as approximately 7,800 undeveloped acres, in the Permian Basin, for net cash proceeds of $129 million. The Company recorded aggregate gains of $68 million associated with these sales.
In May 2019, the Company completed the South Texas Divestiture in exchange for total consideration having an estimated fair value of $210 million. The fair value of the consideration included (i) net cash proceeds of $2 million, (ii) $136 million in contingent consideration and (iii) a $72 million receivable associated with estimated deficiency fees to be paid by the buyer. The Company recorded a loss of $525 million associated with the sale.
Contingent Consideration. Per the terms of the South Texas Divestiture, the Company was entitled to receive contingent consideration based on future annual oil and NGL prices during each of the five years from 2020 to 2024. The Company revalued the contingent consideration using an option pricing model each reporting period prior to the settlement of the contingent consideration in July 2020, at which time, the Company received cash proceeds of $49 million from the buyer to fully satisfy the contingent consideration. The Company recorded a noncash loss of $42 million to interest and other income during the year ended December 31, 2020, associated with the settlement. See Note 4, Note 5 and Note 15 for additional information.

December 31, 2021, 2020 and 2019
Deficiency Fee Obligation. The Company transferred its long-term midstream agreements and associated minimum volume commitments ("MVC") to the buyer of its South Texas assets. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVC from January 2019 through July 2022. The Company determines the fair value of the deficiency fee obligation using a probability weighted discounted cash flow model. The deficiency fee obligation is included in current or noncurrent other liabilities in the consolidated balance sheets, based on the estimated timing of payments. During the year ended December 31, 2021, the Company recorded a decrease of $3 million to the Company's estimated deficiency fee obligations in other expense in the consolidated statements of operations, as a result of lower than forecasted 2021 deficiency fee payments. During the year ended December 31, 2020, the Company recorded a charge of $84 million in other expense in the consolidated statements of operations, to increase the Company's originally forecasted deficiency fee payments as a result of a reduction in planned drilling activities by the buyer. The Company's estimated deficiency fee obligation as of December 31, 2021 of $191 million is included in other current liabilities in the consolidated balance sheets. See Note 4, Note 11 and Note 16 for additional information.
Deficiency Fee Receivable. The buyer is required to reimburse the Company for 18 percent of the deficiency fees paid under the transferred midstream agreements from January 2019 through July 2022. Such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. The Company determines the fair value of the deficiency fee receivable using a credit risk-adjusted valuation model. During the year ended December 31, 2021 and 2020, the Company recorded an increase to the Company's long-term deficiency fee receivable of $7 million and $4 million, respectively, in other expense in the consolidated statements of operations, to reflect the buyer's share of deficiency fees which were greater than originally forecasted as of the date of the sale. The deficiency fee receivable is included in noncurrent other assets in the consolidated balance sheets. See Note 4, Note 11 and Note 16 for additional information.
Restricted Cash. As a condition of the sale, the Company deposited $75 million into an escrow account to be used to fund future MVC payments. Beginning in 2021, the required escrow balance declined to $50 million and during the year ended December 31, 2021, the Company used a portion of the $50 million in the escrow account to make monthly MVC payments. Beginning in 2022, there is no required escrow balance. To the extent that there is any remaining balance after the payment of deficiency fees, the balance will become unrestricted and revert to the Company on March 31, 2023. The escrow account balance is included in restricted cash in the consolidated balance sheets.
Decommissioning. In November 2018, the Company announced plans to close its sand mine located in Brady, Texas and transition its proppant supply requirements to West Texas sand sources. As a result, the Company recorded $23 million of accelerated depreciation, $13 million of inventory and other property and equipment impairment charges and $12 million of sand mine closure-related costs in other expense in the consolidated statements of operations during the year ended December 31, 2019. See Note 16 for additional information.
Restructuring. During 2020, the Company implemented a corporate restructuring to reduce its staffing levels to correspond with a planned reduction in future activity levels (the "2020 Corporate Restructuring"). The restructuring resulted in approximately 300 employees being involuntarily separated from the Company. The Company recorded $78 million of employee-related charges, including $5 million of noncash stock-based compensation expense related to the accelerated vesting of certain equity awards, in other expense in the consolidated statements of operations during the year ended December 31, 2020. See Note 8 and Note 16 for additional information.
During 2019, the Company implemented a corporate restructuring program to align its cost structure with the objectives of the Company (the "2019 Corporate Restructuring Program"). The restructuring occurred in three phases as follows:
In March 2019, the Company made certain changes to its leadership and organizational structure, which included the early retirement and departure of certain officers of the Company.
In April 2019, the Company adopted a voluntary separation program ("VSP") for certain eligible employees, and
In May 2019, the Company implemented an involuntary separation program ("ISP").
During 2019, the Company recorded $159 million of employee-related charges, including $26 million of noncash stock-based compensation expense related to the accelerated vesting of certain equity awards, associated with the 2019 Corporate

See Note 16 for additional information.
NOTE 4. Fair Value Measurements
The Company determines fair value based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company's own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety.
The three input levels of the fair value hierarchy are as follows:
Level 1 – quoted prices for identical assets or liabilities in active markets.
Level 2 – quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g. interest rates) and inputs derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – unobservable inputs for the asset or liability, typically reflecting management's estimate of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including discounted cash flow models.

Commodity price derivatives. The Company's commodity price derivatives primarily represent oil and gas swap contracts, collar contracts, collar contracts with short puts, option contracts and basis swap contracts. The asset and liability measurements for the Company's commodity price derivative contracts are determined using Level 2 inputs. The Company utilizes discounted cash flow and option-pricing models for valuing its commodity price derivatives.
The asset and liability values attributable to the Company's commodity price derivatives were determined based on inputs that include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) the implied rate of volatility inherent in the collar contracts, collar contracts with short puts and option contracts, which is based on active and independent market-quoted volatility factors.
Marketing derivatives. Under the contract terms of the marketing derivatives, the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland oil price and the price the Company receives for the oil volumes sold is a weighted average sales price ("WASP") that the non-affiliated counterparty receives for selling oil through a Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the marketing contracts, the Company determined that the marketing contracts should be accounted for as derivative instruments not designated as hedges.

The asset and liability measurements for the Company's marketing derivative contracts are determined using both Level 2 and 3 inputs. The Company utilizes a discounted cash flow model for valuing its marketing derivatives.
The asset and liability values attributable to the Company's marketing derivative were determined based on Level 2 inputs that include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) stated contractual rates. The Level 3 inputs attributable to the Company's marketing derivatives include the historical monthly differential between Brent oil prices and the corresponding WASP of the counterparty to the marketing derivatives ("WASP Differential Deduction") and, to a lesser extent, an estimated annual cost inflation rate. The average WASP Differential Deduction used in the fair value determination as of December 31, 2021 and 2020 was $2.19 per barrel and $1.91 per barrel, respectively. The WASP Differential Deduction and the estimated annual cost inflation rate reflects management's best estimate of future results utilizing historical performance, but these estimates are not observable inputs by a market participant and contain a high degree of uncertainty. The Company could experience significant mark-to-market fluctuations in the fair value of its marketing derivatives based on changes in the WASP Differential Deduction if it deviates from historical levels. For example, a 10 percent increase or decrease in the WASP Differential Deduction would impact the fair value of the Company's marketing derivatives recorded by approximately $20 million as of December 31, 2021.
Deferred compensation plan assets. The Company's deferred compensation plan assets include investments in equity and mutual fund securities that are actively traded on major exchanges. The fair value of these investments is determined using Level 1 inputs based on observable prices on major exchanges.
Investment in affiliate and short-term investment. The Company elected the fair value option for measuring its equity method investment in ProPetro. The Laredo common stock held by the Company is treated as an investment in equity securities measured at fair value. The fair value of the Company's investments in ProPetro and Laredo common stock are determined using Level 1 inputs based on observable prices on a major exchange. See Note 3, Note 12 and Note 15 for additional information.
Contingent consideration. Per the terms of the South Texas Divestiture, the Company was entitled to receive contingent consideration based on future annual oil and NGL prices during each of the five years from 2020 to 2024. The Company revalued the contingent consideration using an option pricing model each reporting period prior to the settlement of the contingent consideration in July 2020, at which time, the Company received cash proceeds of $49 million from the buyer to fully satisfy the contingent consideration. The Company recorded a noncash loss of $42 million to interest and other income during the year ended December 31, 2020 associated with the settlement. During 2019, the Company recorded a noncash loss of $45 million to interest and other income associated with adjusting the contingent consideration to fair value. The fair value of the contingent consideration was determined using Level 2 inputs based on an option pricing model using quoted future commodity prices from active markets, implied volatility factors and counterparty credit risk assessments. See Note 3 and Note 5 and Note 15 for additional information.
Assets and liabilities measured at fair value on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets and liabilities can include inventories, proved and unproved oil and gas properties, assets acquired and liabilities assumed in business combinations, goodwill and other long-lived assets that are written down to fair value when they are determined to be impaired or held for sale.
Parsley Acquisition and DoublePoint Acquisition. Both the Parsley Acquisition and DoublePoint Acquisition were accounted for using the acquisition method under ASC Topic 805, "Business Combinations", which requires all assets acquired and liabilities assumed in the acquisitions to be recorded at fair values at the acquisition date of each transaction. Oil and gas properties were valued based on income and market based approaches utilizing Level 3 inputs, including internally generated development and production profiles and price and cost assumptions. Debt assumed in the acquisitions was valued based on Level 2 inputs that included using observable market prices to determine fair value. Net derivative liabilities assumed in the acquisitions were valued based on Level 2 inputs similar to the Company's other commodity price derivatives. See Note 3 for additional information.
South Texas Divestiture. The Company recorded a deficiency fee obligation and related deficiency fee receivable in conjunction with the South Texas Divestiture. The fair value of the deficiency fee obligation and deficiency fee receivable was determined using Level 3 inputs based on a probability-weighted forecast that considers historical results, market conditions and various development plans to arrive at the estimated present value of the deficiency payments and corresponding receipts. Changes to the Company's forecasted deficiency fee obligation and estimated deficiency fee receivable are recorded in other

expense in the consolidated statements of operations. For the year ended December 31, 2021, the Company recorded a decrease in the deficiency fee obligation of $3 million and an increase to the deficiency fee receivable of $7 million. For the year ended December 31, 2020, the Company recorded an increase in the deficiency fee obligation of $84 million and an increase to the deficiency fee receivable of $4 million. The Company will not increase the estimated deficiency fee receivable associated with 2022 forecasted deficiencies until they are realizable. The present value of the future cash payments and expected cash receipts were determined using a 3.6 percent and 3.2 percent discount rate, respectively, based on the estimated timing of future payments and receipts and the Company's counterparty credit risk assessments. See Note 3, Note 11 and Note 16 for additional information.
Other assets. During the year ended December 31, 2019, the Company impaired the remaining $13 million of inventory and other property and equipment related to the decommissioning of the Company's Brady, Texas sand mine, as these assets had no remaining future economic value. In addition, the Company recognized a $16 million impairment charge related to pressure pumping assets that had no future benefit to the Company. See Note 16 for additional information.
Proved oil and gas properties. The Company performs assessments of its proved oil and gas properties, which are accounted for under the successful efforts method of accounting, whenever events or circumstances indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future cash flows, including cash flows from the Company's water services business that are used in the development of the assets, is less than the carrying amount of the assets, including the carrying value of the water services business. In these circumstances, the Company recognizes an impairment charge for the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets.
Based on management's commodity price outlooks as of December 31, 2021, which represent longer-term commodity price outlooks that are developed based on third party future commodity price estimates as of a measurement date ("Management's Price Outlooks"), the Company determined events and circumstances did not indicate that the carrying value of the Company's proved properties were not recoverable.
Unproved oil and gas properties. Unproved oil and gas properties are periodically assessed for impairment on a project-by-project basis. These impairment assessments are affected by the results of exploration activities, commodity price outlooks, planned future property sales or expiration of all or a portion of such projects. If the Company's assessment determines that a project is not expected to be developed or is unlikely to recover its costs, the Company will recognize an impairment charge at that time. Impairment charges for unproved oil and gas properties are recorded in exploration and abandonments in the consolidated statements of operations. During 2021, 2020 and 2019, the Company recorded $4 million, $11 million and $4 million, respectively, to exploration and abandonments in the consolidated statements of operations.
Goodwill. Goodwill is assessed for impairment whenever it is more likely than not that events or circumstances indicate the carrying value of a reporting unit exceeds its fair value, but no less often than annually. An impairment charge is recorded for the amount by which the carrying amount exceeds the fair value of a reporting unit in the period it is determined to be impaired.
Based on the Company's annual assessment of the fair value of goodwill as of July 1, 2021, the Company determined that its goodwill was not impaired. As of December 31, 2021, there were no material changes in events or circumstances that would warrant a reassessment for impairment.

The Company has other financial instruments consisting primarily of receivables, payables and other current assets and liabilities that approximate fair value due to the nature of the instrument and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in business combinations, goodwill and asset retirement obligations.
NOTE 5. Derivative Financial Instruments
The Company's derivatives are accounted for as non-hedge derivatives and all changes in the fair values of its derivative contracts are recognized as gains or losses in the earnings of the periods in which they occur.
Oil production derivatives. The Company sells its oil production at the lease and the sales contracts governing such oil production are tied directly to, or are correlated with, NYMEX WTI oil prices. The Company also enters into (i) pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from its areas of production and (ii) purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil pricing to Gulf Coast refineries or international export markets at prices that are highly correlated to Brent oil prices. As a result, the Company uses a combination of Brent, MEH and WTI derivative contracts to manage future oil price volatility.
The Company recorded oil derivatives losses of $508 million in the consolidated statement of operations during the year ended December 31, 2021 associated with (i) the termination of certain of its 2022 oil commodity derivative positions and (ii) entering into equal and offsetting oil commodity derivative trades, which had the net effect of eliminating certain of its 2022 derivative positions.

The Company has also entered into derivative contracts for 3,000 Bbls per day of Brent basis swaps for January 2024 through December 2024 production. The basis swap contracts fix the basis differential between the WTI index price at which the Company sells a portion of its Permian Basin oil and the Brent index price at a weighted average of $4.33.
NGL production derivatives. All material physical sales contracts governing the Company's NGL production are tied directly or indirectly to Mont Belvieu, Texas NGL component product prices. The Company periodically uses derivative contracts to manage the volatility of NGL component product prices. As of December 31, 2021, the Company did not have any NGL derivative contracts outstanding.
Gas production derivatives. All material physical sales contracts governing the Company's gas production are tied directly or indirectly to NYMEX HH gas prices or regional index prices (e.g. WAHA, SoCal and Houston Ship Channel) where the gas is sold. To diversify the gas prices it receives to international market prices, the Company sells a portion of its gas production at Dutch TTF prices. The Company uses derivative contracts to manage gas price volatility and basis swap contracts to reduce basis risk between HH prices and actual index prices at which the gas is sold.
The Company recorded derivatives losses of $13 million in the consolidated statement of operations during the year ended December 31, 2021 associated with (i) the termination of certain of its 2022 gas commodity derivative positions and (ii) entering into equal and offsetting gas commodity derivative trades, which had the net effect of eliminating certain of its 2022 derivative positions.

Marketing derivatives. The Company uses marketing derivatives to diversify its oil pricing to Gulf Coast and international markets. The Company's marketing derivatives reflect two long-term marketing contracts that were entered in October 2019 whereby the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that began on January 1, 2021 and ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland oil price and the price the Company receives for the oil volumes sold is a WASP that a non-affiliated counterparty receives for selling oil through a Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the marketing contracts, the Company determined that the marketing contracts should be accounted for as derivative instruments.
Contingent consideration. The Company's right to receive contingent consideration in conjunction with the South Texas Divestiture was determined to be a derivative financial instrument that is not designated as a hedging instrument. Prior to its settlement in July 2020, the contingent consideration was revalued using an option pricing model each reporting period based on forecasted oil and NGL prices during each of the five years from 2020 to 2024. The Company recorded losses of $42 million and $45 million related to the revaluation of the contingent consideration to interest and other income (loss), net in the consolidated statements of operations for the years ended December 31, 2020 and 2019, respectively. See Note 3, Note 4 and Note 15 for additional information.

Credit facility. The Company maintains a revolving corporate credit facility (the "Credit Facility") with a syndicate of financial institutions and has aggregate loan commitments of $2.0 billion. On January 12, 2021, Pioneer entered into the First Amendment to Credit Agreement (the "Amendment") with Wells Fargo Bank, National Association, as Administrative Agent, and the other agents and lenders party thereto (the "Syndicate"). The primary changes attributable to the Amendment were to increase the aggregate loan commitments from $1.5 billion to $2.0 billion, extend the maturity of the Credit Facility to January 12, 2026 and to nominally adjust the drawn and undrawn pricing. As of December 31, 2021, the Company had no outstanding borrowings under the Credit Facility.
Borrowings under the Credit Facility may be in the form of revolving loans or swing line loans. Revolving loans represent loans made ratably by the Syndicate in accordance with their respective commitments under the Credit Facility and bear interest, at the option of the Company, based on (a) a rate per annum equal to the higher of the prime rate announced from time to time by Wells Fargo Bank, National Association or the weighted average of the rates on overnight federal funds transactions with members of the Federal Reserve System during the last preceding business day plus 0.5 percent plus a defined alternate base rate spread margin, which is currently 0.25 percent based upon the Company's debt rating or (b) a base Eurodollar rate, plus a margin (the "Applicable Margin"), which is currently 1.25 percent and is also determined by the Company's debt rating. Swing line loans represent loans made by a subset of the lenders in the Syndicate and may not exceed $150 million. Swing line loans under the Credit Facility bear interest at a rate per annum equal to the "ASK" rate for federal funds periodically published by the Dow Jones Market Service plus the Applicable Margin. Letters of credit outstanding under the Credit Facility are subject to a per annum fee, representing the Applicable Margin plus 0.125 percent. The Company also pays commitment fees on undrawn amounts under the Credit Facility that are determined by the Company's debt rating (currently 0.15 percent). Borrowings under the Credit Facility are general unsecured obligations.
The Credit Facility requires the maintenance of a ratio of total debt to book capitalization, subject to certain adjustments, not to exceed 0.65 to 1.0. As of December 31, 2021, the Company was in compliance with its debt covenants.
Assumption of DoublePoint notes and payoff of DoublePoint credit facility. In connection with the completion of the DoublePoint Acquisition, the Company assumed DoublePoint's outstanding senior notes of $650 million in aggregate principal amount of 7.75% senior notes due 2025 (with a fair value of $735 million) and DoublePoint's credit facility with an outstanding balance of $240 million. The Company repaid and terminated the DoublePoint credit facility agreement on May 4, 2021.
Assumption of Parsley notes and payoff of Parsley credit facility. In connection with the completion of the Parsley Acquisition, the Company assumed Parsley's outstanding senior notes (the "Parsley Notes") of $2.7 billion in aggregate principal amount (with a fair value of $2.8 billion) and Parsley's credit facility with an outstanding balance of $397 million. The Company's senior notes are structurally subordinated to the outstanding Parsley Notes. The Company repaid and terminated the Parsley credit facility agreement on January 12, 2021.
Senior notes. In May 2021, the Company issued $750 million of 0.550% senior notes that will mature May 15, 2023 (the "May 2021 Senior Notes Offering"). The Company received proceeds, net of $4 million of issuance costs and discounts, of $746 million. Interest on the notes will be payable on May 15 and November 15 of each year.
The Company used $731 million of the proceeds from the May 2021 Senior Notes Offering to redeem DoublePoint's 7.750% senior notes due 2025. Associated with the redemption, the Company recognized a $3 million gain on the early extinguishment of debt. See Note 16 for additional information.
In January 2021, the Company issued $750 million of 0.750% senior callable notes that will mature January 15, 2024, $750 million of 1.125% senior notes that will mature January 15, 2026 and $1.0 billion of 2.150% senior notes that will mature January 15, 2031 (the "January 2021 Senior Notes Offering"). The Company received proceeds, net of $24 million of issuance costs and discounts, of $2.5 billion. Interest on each of the new notes will be payable on January 15 and July 15 of each year.
The Company used the proceeds from the January 2021 Senior Notes Offering to pay (i) $1.6 billion to redeem Parsley's 5.250% senior notes due 2025, Parsley's 5.375% senior notes due 2025 and Jagged Peak's 5.875% senior notes due 2026 and (ii) $852 million to purchase a portion of Parsley's 5.625% senior notes due 2027 and Parsley's 4.125% senior notes due 2028 pursuant to a cash tender offer. In connection with the tender offers, the Company also obtained the requisite consents from holders of Parsley's 5.625% senior notes due 2027 and 4.125% senior notes due 2028 to amend the indentures pursuant to which the notes were issued to, among other things, (i) eliminate substantially all of the restrictive covenants and related provisions and certain events of default contained in each indenture and (ii) shorten the minimum notice requirement for

optional redemptions to three days. Associated with the redemption and tenders, the Company recognized a $5 million loss on the early extinguishment of debt. See Note 16 for additional information.
During August 2020, the Company issued $1.1 billion of 1.900% senior notes that will mature August 15, 2030. The Company received proceeds of $1.08 billion, net of $18 million of issuance costs and discounts. Interest on the notes will be payable on February 15 and August 15 of each year.
In May 2020, the Company paid $725 million to complete a cash tender offer for certain of its outstanding senior notes. Associated with the tender offer, the Company settled $360 million of its 3.450% senior notes due 2021, $356 million of its 3.950% senior notes due 2022 and $9 million of its 7.200% senior notes due 2028. The Company expensed unamortized debt discounts and issuance costs associated with the tendered notes of $2 million and recognized a loss on the early extinguishment of debt totaling $23 million. The losses are recorded in other expense in the consolidated statements of operations. See Note 16 for additional information.
The Company's 3.450% senior notes and 7.500% senior notes, with debt principal balances of $140 million and $450 million, respectively, matured and were repaid in January 2021 and January 2020, respectively. The Company funded the repayments with cash on hand.
The Company's 3.950% senior notes, with a debt principal balance of $244 million, will mature in July 2022. The 3.950% senior notes are recorded in the current portion of long-term debt in the consolidated balance sheets as of December 31, 2021.
The Company's senior notes are general unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company and are senior in right of payment to all existing and future subordinated indebtedness of the Company. The Company is a holding company that conducts all of its operations through subsidiaries; consequently, the senior notes are structurally subordinated to all obligations of its subsidiaries. Interest on the Company's senior notes is payable semiannually.
Convertible senior notes. In May 2020, the Company issued $1.3 billion principal amount of convertible senior notes due 2025. The Convertible Notes bear a fixed interest rate of 0.250% per year, with interest payable on May 15 and November 15 of each year. The Convertible Notes will mature on May 15, 2025, unless earlier redeemed, repurchased or converted. The Convertible Notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.
The Convertible Notes are convertible into shares of the Company's common stock at an adjusted conversion rate of 9.3647 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes (subject to further adjustment pursuant to the terms of the notes indenture, the "Conversion Rate"), which represents an adjusted conversion price of $106.78 per share (subject to adjustment pursuant to the terms of the notes indenture, the "Conversion Price"). Upon conversion, the Convertible Notes will be settled in cash, shares of the Company's common stock or a combination thereof, at the Company's election.
Holders of the Convertible Notes may convert their notes at their option prior to February 15, 2025 under the following circumstances:
during the quarter following any quarter during which the last reported sales price of the Company's common stock for at least 20 of the last 30 consecutive trading days of such quarter exceeds 130 percent of the Conversion Price;
during the five-day period following any five consecutive trading day period when the trading price of the Convertible Notes is less than 98 percent of the price of the Company's common stock times the Conversion Rate;
upon notice of redemption by the Company; or
upon the occurrence of specified corporate events, including certain consolidations or mergers.
On or after February 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time. The Company may not redeem the Convertible Notes prior to May 20, 2023, and after such date, may redeem the Convertible Notes only if the last reported sale price of the Company's common stock has been at least 130 percent of the Conversion Price for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides the notice of redemption. The redemption price is equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest.

During the last 30 consecutive trading days of the fourth quarter of 2021, the last reported sale price of the Company's common stock exceeded 130 percent of the Conversion Price for at least 20 trading days, causing the Convertible Notes to become convertible at the option of the holders during the three month period ending March 31, 2022. The Company reserves its right under the notes indenture to elect to settle the Convertible Notes in cash, shares of the Company's common stock or a combination of cash and common stock.
The Company early adopted ASU 2020-06 on January 1, 2021. Upon issuance of the Convertible Notes in May 2020, the Company bifurcated the debt and equity components of the Convertible Notes between long-term debt and additional paid-in capital in its consolidated balance sheet. The amount recorded to additional paid-in capital represented a debt discount that was being amortized to interest expense over the life of the Convertible Notes. As part of the adoption of ASU 2020-06, the Company (i) reversed the debt discount and related deferred income tax liability recorded to additional paid-in capital of $230 million and $50 million, respectively, (ii) recorded a cumulative effect of the adoption of ASU 2020-06 of $22 million to retained earnings, representing the reversal of the $28 million debt discount that was amortized to interest expense, net of an associated deferred income tax impact of $6 million, in 2020 and (iii) recorded the respective offsets for items (i) and (ii) above, representing the unamortized debt discount attributable to the Convertible Notes of $202 million to long-term debt and the associated deferred tax impact of $44 million to deferred income tax liabilities. See Note 2 for additional information.
As of December 31, 2021, the Convertible Notes had an outstanding principal balance of $1.3 billion and unamortized issuance costs of $16 million. The effective interest rate related to interest expense to be recorded over the life of the Convertible Notes is 0.6 percent.
Interest expense recognized on the Convertible Notes is as follows:

______________________
(a)Upon adoption of ASU 2020-06, the Company no longer amortizes the issuance discount associated with the Convertible Notes to interest expense over the life of the Convertible Notes. See Note 2 for additional information.

Capped call transactions. In connection with the issuance of the Convertible Notes, the Company entered into privately negotiated capped call transactions with certain financial institution counterparties (the "Capped Call"), the purpose of which was to reduce the potential dilution to the Company's common stock upon conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of such converted notes, with such reduction and offset subject to a capped price. The Capped Call transactions have an adjusted strike price of $106.78 per share of common stock and an adjusted capped price of $151.96 per share of common stock. The net costs of $113 million incurred to purchase the Capped Call transactions were recorded as a reduction to additional paid-in capital in the accompanying consolidated balance sheets.

Long-Term Incentive Plan. The Company's Amended and Restated 2006 Long-Term Incentive Plan ("LTIP") provides for the granting of various forms of awards, including stock options, stock appreciation rights, performance units, restricted stock and restricted stock units to directors, officers and employees of the Company.
In connection with the Parsley Acquisition, the Company assumed all rights and obligations under the Amended and Restated Parsley Energy, Inc. 2014 Long-Term Incentive Plan (the "2014 Parsley Plan") and the Jagged Peak Energy Inc. 2017 Long-Term Incentive Plan (the "Jagged Peak Plan") and together with the 2014 Parsley Plan, (the "Parsley Plans"). The awards outstanding under the Parsley Plans were assumed by the Company and were automatically converted into an award with the right to receive a number of shares of Pioneer common stock that is equal to the product of the number of shares of Parsley common stock subject to such award under the Parsley Plans as of the acquisition date and the Exchange Ratio (0.1252). As a result, 37,299 shares of Pioneer common stock are issuable by the Company upon settlement of the outstanding awards granted under the 2014 Parsley Plan and 1,166 shares of Pioneer common stock are issuable by the Company upon settlement of the outstanding awards granted under the Jagged Peak Plan.

______________________
(a)Under New York Stock Exchange rules, the Company added the shares that were available under the 2014 Parsley Plan to the LTIP. These shares can only be used for grants to employees who were not employed or engaged by Pioneer or any of its subsidiaries immediately before the Parsley Acquisition and such awards may only be granted through May 22, 2024, the date that the 2014 Parsley Plan would have otherwise expired.
Employee Stock Purchase Plan. The Company's Employee Stock Purchase Plan ("ESPP") allows eligible employees to annually purchase the Company's common stock at a discounted price. Officers of the Company are not eligible to participate in the ESPP. Contributions to the ESPP are limited to 15 percent of an employee's base salary (subject to certain ESPP limits) during the eight-month offering period (January 1 to August 31). Participants in the ESPP purchase the Company's common stock at a price that is 15 percent below the closing sales price of the Company's common stock on either the first day or the last day of each offering period, whichever closing sales price is lower.

Performance unit awards. Each year, at its discretion, the board of directors of the Company awards performance units to certain of the Company's officers under the LTIP. The number of shares of common stock to be issued is determined by comparing the Company's total shareholder return to the total shareholder return of a predetermined group of peer companies over the performance period. The performance unit awards vest over a 34-month service period.
The grant-date fair value per unit of the 2021, 2020 and 2019 performance unit awards were $165.32, $184.06 and $165.84, respectively, and are being recorded as stock-based compensation expense ratably over the performance period. The fair value of the performance unit awards was determined using the Monte Carlo simulation model that utilizes multiple input variables to determine the probability of satisfying the market condition stipulated in the award grant and calculates the fair value of the award. Expected volatilities utilized in the model were estimated using a historical period consistent with the performance period of approximately three years. The risk-free interest rate was based on the United States Treasury rate for a term commensurate with the expected life of the grant.
Assumptions used to estimate the fair value of performance unit awards granted in each of the following years are as follows:

(a)Amount reflects the number of performance units initially granted. The actual payout of shares upon vesting may be between zero and 250 percent of the performance units included in this table depending upon the total shareholder return ranking of the Company compared to peer companies at the vesting date.
(b)Units vested reflects the number of performance units that vest upon retirement or departure of eligible officers or when the service period on the award has ended. Awards that vest upon retirement or departure of eligible officers are not transferred to the officer until the original service period of the award lapses. None of the 76,167 units that vested are associated with eligible officer retirements in 2021. On December 31, 2021, the service period lapsed on 86,483 performance unit awards that earned 1.55 shares for each vested award resulting in 134,059 aggregate shares of common stock being issued on January 3, 2022. Of the 86,483 performance unit awards that lapsed, 10,316 units were associated with units that vested in prior years upon retirement or departure of eligible officers.
In addition, during the year ended December 31, 2021, the Company assumed 100,056 Parsley performance units which immediately vested upon completion of the Parsley Acquisition.
The grant-date fair value of performance units that vested during 2021, 2020 and 2019 was $13 million, $10 million and $22 million, respectively. The total fair value of performance units that vested during 2021, 2020 and 2019 was $14 million, $5 million, and $13 million, respectively.

The Company's asset retirement obligations primarily relate to the future plugging and abandonment of wells and related facilities. Market risk premiums associated with asset retirement obligations are estimated to represent a component of the Company's credit-adjusted risk-free rate that is utilized in the calculations of asset retirement obligations.

(a)Changes in estimates are determined based on several factors, including updating abandonment cost estimates using recent actual costs incurred to abandon wells, credit-adjusted risk-free discount rates, economic well life estimates and forecasted timing of abandoning wells. The 2020 change in estimate is primarily due to decreases in commodity prices, which had the effect of shortening well life estimates and increasing the present value of the abandonment obligation.

Severance agreements. As of December 31, 2021, the Company has entered into severance and change in control agreements with certain of its officers and key employees. The current annual salaries for the officers and key employees covered under such agreements total $14 million.
Indemnifications. The Company has agreed to indemnify its directors and certain of its officers, employees and agents with respect to claims and damages arising from acts or omissions taken in such capacity, as well as with respect to certain litigation.
Legal actions. The Company is party to various proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to these proceedings and claims will not have a material adverse effect on the Company's consolidated financial position as a whole or on its liquidity, capital resources or future annual results of operations. The Company records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated.

Environmental. Environmental expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Environmental expenditures that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. Liabilities for expenditures that will not qualify for capitalization are recorded when environmental assessment and/or remediation is probable and the costs can be reasonably estimated. Such liabilities are undiscounted unless the timing of cash payments for the liability is fixed or reliably determinable. Environmental liabilities normally involve estimates that are subject to revision until settlement or remediation occurs.
Obligations following divestitures. In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalty and income taxes. Also associated with its divestiture transactions, the Company has issued and received guarantees to facilitate the transfer of contractual obligations, such as firm transportation agreements or gathering and processing arrangements. The Company does not recognize a liability if the fair value of the obligation is immaterial and the likelihood of making payments under these guarantees is remote.
South Texas Divestiture. In conjunction with the South Texas Divestiture, the Company transferred its long-term midstream agreements and associated MVCs to the buyer. However, the Company retained the obligation to pay 100 percent of any deficiency fees associated with the MVCs from January 2019 through July 2022. The buyer is required to reimburse the Company for 18 percent of the deficiency fees paid by the Company from January 2019 through July 2022; such reimbursement will be paid by the buyer in installments beginning in 2023 through 2025. Assuming 100 percent of the MVCs are paid as deficiency fees, the maximum amount of future payments for this obligation would be approximately $211 million as of December 31, 2021. The Company's estimated deficiency fee obligation as of December 31, 2021 of $191 million is included in other current liabilities in the consolidated balance sheets. The corresponding estimated deficiency fee receivable from the buyer of $84 million is included in noncurrent other assets in the consolidated balance sheets. The Company has received credit support for the deficiency fee receivable of up to $100 million.
Raton transportation commitments. As part of the Raton Basin Sale, the Company transferred certain gas transportation commitments, which extend through 2032, to the buyer for which the Company has provided a guarantee. Assuming 100 percent of the remaining commitments are paid by the Company under its guarantee, the maximum amount of future payments would be approximately $72 million as of December 31, 2021. The Company has received credit support for the commitments of up to $50 million. The Company paid $6 million in gas transportation fees associated with the transferred commitment for the year ended December 31, 2021 and was fully reimbursed.
West Eagle Ford Shale commitments. In April 2018, the Company completed the sale of its West Eagle Ford Shale gas and liquids field to an unaffiliated third party and transferred certain gas and liquids transportation commitments, which extend through 2022, to the buyer for which the Company has provided a guarantee. Assuming 100 percent of the remaining commitments are paid by the Company under its guarantee, the maximum amount of future payments would be approximately $15 million as of December 31, 2021. The Company has received credit support for the commitments of up to $17 million.
Certain contractual obligations were retained by the Company after certain divestitures, primarily the South Texas Divestiture. These contractual obligations are primarily related to firm transportation and storage agreements in which the Company is unlikely to realize any benefit. The estimated obligations are included in other current or noncurrent liabilities in the consolidated balance sheets and changes are as follows:

NOTE 12. Related Party Transactions
In December 2018, the Company completed the sale of its pressure pumping assets to ProPetro in exchange for 16.6 million shares of ProPetro common stock and $110 million of cash that was received during the first quarter of 2019. ProPetro is considered a related party as the shares received represent 16 percent of ProPetro's outstanding common stock. In addition to the sale of equipment and related facilities, the Company entered into a long-term agreement with ProPetro for it to provide pressure pumping and related services. The costs of these services are capitalized in oil and gas properties as incurred.
In October 2019, Phillip A. Gobe, a nonemployee member of the Company's board of directors, was appointed by the board of directors of ProPetro to serve as its Executive Chairman, and in March 2020 he was appointed as Chief Executive Officer and Chairman of the board of directors of ProPetro. On August 31, 2021, Mr. Gobe transitioned from ProPetro's Chairman and Chief Executive Officer to its Executive Chairman. Mark S. Berg, the Company's Executive Vice President, Corporate Operations, serves as a member of the ProPetro board of directors under the Company's right to designate a director

The loss of the above major purchaser of purchased oil and gas would not be expected to have an adverse effect on the ability of the Company to sell commodities it purchases from third parties.
NOTE 14. Revenue Recognition
Disaggregated revenue from contracts with purchasers. Revenues on sales of oil, NGL, gas and purchased oil, gas and diesel are recognized when control of the product is transferred to the purchaser and payment can be reasonably assured. Sales prices for oil, NGL and gas are negotiated based on factors normally considered in the industry, such as an index or spot price, distance from the well to the pipeline or market, commodity quality and prevailing supply and demand conditions. Accordingly, the prices received by the Company for oil, NGL and gas generally fluctuate similar to changes in the relevant market index prices.
Disaggregated revenue from contracts with purchasers by product type is as follows:
Year Ended December 31,
20212020
 (in millions)
Oil sales$8,808 $2,871 
NGL sales1,707 490

Sales of purchased gas62 24 
Sales of purchased diesel58 11 
Total sales of purchased commodities6,367 3,394 
$17,870 $7,024 
Performance obligations and contract balances. The majority of the Company's product sale commitments are short-term in nature with a contract term of one year or less. The Company typically satisfies its performance obligations upon transfer of control as described above in Disaggregated revenue from contracts with purchasers and records the related revenue in the month production is delivered to the purchaser. Settlement statements for sales of oil, NGL, gas and sales of purchased oil, gas and diesel may not be received for 30 to 60 days after the date the volumes are delivered, and as a result, the Company is required to estimate the amount of volumes delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. As of December 31, 2021 and 2020, the accounts receivable balance representing amounts due or billable under the terms of contracts with purchasers is $1.6 billion and $661 million, respectively.

During the year ended December 31, 2021, the Company divested its well services business and continues to operate its water services business. See Note 3 for additional information.
NOTE 17. Income Taxes
The Company and its eligible subsidiaries file a consolidated U.S. federal income tax return. Certain subsidiaries are not eligible to be included in the consolidated U.S. federal income tax return and separate provisions for income taxes have been determined for these entities or groups of entities. The tax returns and the amount of taxable income or loss are subject to examination by U.S. federal, state, local and foreign taxing authorities.
The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that deferred tax assets can be realized prior to their expiration. Pioneer monitors Company-specific, oil and gas industry and worldwide economic factors and based on that information, along with other data, reassesses the likelihood that the Company's net operating loss carryforwards ("NOLs") and other deferred tax attributes in the U.S. federal, state, local and foreign tax jurisdictions will be utilized prior to their expiration.
DoublePoint Acquisition. The Company purchased all the membership interests of DoublePoint, a disregarded entity for federal income tax purposes. As a result, for tax purposes, the Company recorded the cost basis in the assets acquired equal to its purchase price (i.e. stepped-up basis).
Parsley Acquisition. For federal income tax purposes, the Parsley Acquisition qualified as a tax-free merger whereby the Company acquired carryover tax basis in Parsley's assets and liabilities. The Company recorded a deferred tax liability of $133 million associated with the acquired assets. Included in the deferred tax liability are deferred tax asset attributes acquired from Parsley, which primarily consisted of net operating loss carryforwards of $2.3 billion that are subject to an annual limitation under Internal Revenue Code Section 382. The Company believes it is more likely than not that the acquired net operating loss carryforwards will be utilized before they expire. Offsetting the deferred tax assets attributes are deferred tax liability attributes, primarily related to the cost basis in oil and gas properties for tax purposes being less than the recorded book amounts.
Enactment of the Consolidated Appropriations Act, 2021. On December 27, 2020, President Trump signed into law the Consolidated Appropriations Act, 2021 ("the Act"). The Act includes many tax provisions, including the extension of various expiring provisions, extensions and expansions of certain earlier pandemic tax relief provisions, among other things. The Act did not have a material impact on the Company's current year tax provision or the Company's consolidated financial statements.
Enactment of the Coronavirus Aid, Relief and Economic Security Act. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"). The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act did not have a material impact on the Company's current year tax provision or the Company's consolidated financial statements.

Uncertain tax positions. As of December 31, 2021, the Company has state unrecognized tax benefits ("UTBs") for tax years 2013 and 2015 through 2018 resulting from research and experimental expenditures related to horizontal drilling and completion innovations. The issues related to the claims are complex and uncertain, and the Company cannot conclude that it is more likely than not that it will sustain the claims. Accordingly, no tax benefit has been recognized for the filed claims. The Company believes it will substantially resolve the uncertainties associated with the state UTBs within the next twelve months.

Reserve Quantity Information
The estimates of the Company's proved reserves as of December 31, 2021, 2020 and 2019 were based on evaluations prepared by the Company's engineers and audited by independent petroleum engineers with respect to the Company's major properties and prepared by the Company's engineers with respect to all other properties. Proved reserves were estimated in accordance with guidelines established by the SEC and the FASB, which require that reserve estimates be prepared under existing economic and operating conditions based upon an average of the first-day-of-the-month commodity price during the 12-month period ending on the balance sheet date with no provision for price and cost escalations except by contractual arrangements.
Proved reserve quantity estimates are subject to numerous uncertainties inherent in the estimation of quantities of proved reserves and in the projection of future rates of production and the timing of development expenditures. The accuracy of such estimates is a function of the quality of available data and of engineering and geological interpretation and judgment. Results of subsequent drilling and production performance may cause either upward or downward revision of previous estimates. Further, the volumes considered to be commercially recoverable fluctuate with changes in commodity prices and operating costs. The Company emphasizes that proved reserve estimates are inherently imprecise and that estimates of new discoveries are more imprecise than those of currently producing oil and gas properties. Accordingly, these estimates are expected to change as additional information becomes available in the future.

(a)The proved gas reserves as of December 31, 2021, 2020 and 2019 include 186,325 MMcf, 115,239 MMcf and 100,236 MMcf, respectively, of gas that the Company expected to be produced and utilized as field fuel.
(b)Production for 2021, 2020 and 2019 includes 15,420 MMcf, 11,201 MMcf and 11,781 MMcf of gas consumed as field fuel, respectively.

Revisions of previous estimates. Revisions of previous estimates are comprised of 111 MMBOE of negative technical revisions for 2021 and 145 MMBOE and 26 MMBOE of positive technical revisions for 2020 and 2019, respectively. The negative technical revisions in 2021 are primarily attributable to (i) 55 MMBOE related to reductions in estimates of future production associated with producing wells, (ii) 32 MMBOE related to the removal of 36 proved undeveloped locations that are not expected to be drilled in the time frame originally anticipated and (iii) 24 MMBOE primarily related to vertical wells that are near the end of their productive life or were either plugged and abandoned or shut-in pending being plugged and abandoned. The positive technical revisions in 2020 are primarily attributable to 167 MMBOE of positive NGLs and gas revisions as a result of (i) increasing wet gas production (as a percentage of a horizontal well's total production) over time, (ii) new processing facilities and takeaway capacity being placed into service during 2019 and 2020, which had the effect of lowering line pressures, and (iii) increased recovery rates for NGLs. The positive technical revisions for 2019 are primarily attributable to improved performance from horizontal wells placed on production in the Spraberry/Wolfcamp oil field in the Midland Basin. Revisions of previous estimates associated with changes in NYMEX oil and gas prices resulted in positive price revisions of 72 MMBOE in 2021 and negative price revisions of 83 MMBOE and 11 MMBOE in 2020 and 2019, respectively.

Extensions and discoveries. Extensions and discoveries for 2021, 2020 and 2019 were primarily comprised of proved reserve additions attributable to the Company's successful horizontal drilling program in the Spraberry/Wolfcamp oil field in the Midland Basin. During 2021, 2020 and 2019, the Company drilled 488, 242 and 280 gross productive exploratory/extension wells, respectively, and added 36, 28 and 41 of proved undeveloped locations, respectively. Associated therewith, during 2021, 2020 and 2019, the Company added 482 MMBOE, 212 MMBOE and 276 MMBOE of net reserves from extensions and discoveries, respectively, of which 30 MMBOE, 29 MMBOE and 36 MMBOE, respectively, were recorded as proved undeveloped reserves. The Permian Basin's geology is complex, consisting of multiple stacked horizons/zones, each with its own unique characteristics. The Company recognizes proved undeveloped reserves on undrilled acreage directly offsetting development areas that are reasonably certain of production when drilled, or when reliable technology provides reasonable certainty of economic producibility.
Sales of minerals-in-place. Sales of minerals-in-place in 2021 are primarily related to the Delaware Divestiture and Glasscock Divestiture, reflecting sales of minerals-in-place of 158 MMBOE and 13 MMBOE, respectively. In 2020, sales of minerals-in-place were primarily related to divesting non-core Permian Basin unproved properties and associated producing wells. In 2019, sales of minerals-in-place were primarily related to the sale of the Company's Eagle Ford assets and other remaining South Texas assets. See Note 3 to the accompanying financial statements for additional information.
Purchases of minerals-in-place. Purchases of minerals-in-place in 2021 are primarily related to the Parsley Acquisition and the DoublePoint Acquisition, reflecting the addition of 546 MMBOE and 361 MMBOE, respectively, of net reserves, including the addition of 60 and 248 proved undeveloped locations, respectively. In 2020 and 2019, purchases of minerals-in-place were primarily related to acquisitions in the Company's Spraberry/Wolfcamp oil field in the Midland Basin.

As of December 31, 2021, the Company had 305 proved undeveloped well locations, as compared to 60 for both December 31, 2020 and 2019. The Company has no proved undeveloped well locations that are scheduled to be drilled more than five years from their original date of booking.
The changes in proved undeveloped reserves during 2021 were comprised of the following items:
Revisions of previous estimates. Revisions of previous estimates were comprised of 27 MMBOE, primarily related to removing 36 locations that are not expected to be drilled in the time frame originally anticipated, partially offset by 5 MMBOE of positive price revisions.
Extensions and discoveries. Extensions and discoveries were primarily comprised of proved reserve additions attributable to the Company's successful horizontal drilling program in the Spraberry/Wolfcamp oil field in the Midland Basin.
Sales of minerals-in-place. Sales of minerals-in-place were primarily comprised of proved undeveloped reserves included in the Delaware Divestiture.
Purchases of minerals-in-place. Purchases of minerals-in-place were primarily comprised of proved undeveloped reserves associated with the Parsley Acquisition and the DoublePoint Acquisition.
Transfers to proved developed. Transfers to proved developed reserves represented the proved undeveloped reserves associated with 54 undeveloped locations that moved to proved developed as a result of development drilling.
The Company uses both public and proprietary geologic data to establish continuity of the formation and its producing properties. This included seismic data and interpretations (2-D, 3-D and micro seismic); open hole log information (both vertical and horizontally collected) and petrophysical analysis of the log data; mud logs; gas sample analysis; drill cutting samples; measurements of total organic content; thermal maturity; sidewall cores and data measured from the Company's internal core analysis facility. After the geologic area was shown to be continuous, statistical analysis of existing producing wells was conducted to generate areas of reasonable certainty at distances from established production. As a result of this analysis, proved undeveloped reserves for drilling locations within these areas of reasonable certainty were recorded during 2021.
While the Company expects, based on Management's Price Outlooks, that future operating cash flows will provide adequate funding for future development of its proved undeveloped reserves over the next five years, it may also use any combination of internally-generated cash flows, cash and cash equivalents on hand, sales of investments, availability under its Credit Facility, or external financing sources to fund these and other capital expenditures.

(a)Production and cash flows represent the drilling results from the respective year plus the incremental effects of proved undeveloped drilling beginning in 2022.
(b)Future development costs include $26 million of net abandonment costs in years beyond the forecasted years.
The Company's 2021 estimated future production costs attributable to proved undeveloped reserves of $9.05 per BOE are less than the forecasted future production costs attributable to total proved reserves of $13.36 per BOE for the following reasons:
As of December 31, 2021, a significant portion of the Company's proved developed producing wells are comprised of legacy vertical wells that have higher production costs, on a per BOE basis, than the Company's proved developed producing horizontal wells. The total proved reserves production cost per BOE of $13.36 is comprised of $12.35 per BOE for horizontal wells and $26.65 per BOE for vertical wells.
The estimated future production costs of $9.05 per BOE associated with proved undeveloped reserves, comprised entirely of horizontal wells, is marginally lower than the $12.35 per BOE average of the Company's producing horizontal wells included in total proved reserves. The lower costs take into account the initial production rates of new wells, which are higher at the beginning of a well's life, and result in a lower overall production cost, on a per BOE basis, when looked at over the well's total productive life versus a well that is later in its productive life. In addition, the future production costs on proved undeveloped horizontal wells also reflect the economies of scale of adding the wells to existing infrastructure, allowing the Company to spread certain fixed costs over a larger production volume.

Standardized Measure of Discounted Future Net Cash Flows
The standardized measure of discounted future net cash flows is computed by applying commodity prices used in determining proved reserves (with consideration of price changes only to the extent provided by contractual arrangements) to the estimated future production of proved reserves less estimated future expenditures (based on year-end estimated costs) to be incurred in developing and producing the proved reserves, discounted using a rate of ten percent per year to reflect the estimated timing of the future cash flows. Future income taxes are calculated by comparing undiscounted future cash flows to the tax basis of oil and gas properties plus available carryforwards and credits and applying the current tax rates to the difference. The discounted future cash flow estimates do not include the effects of the Company's commodity derivative contracts.
Discounted future cash flow estimates, like those shown below, are not intended to represent estimates of the fair value of oil and gas properties. Estimates of fair value should also consider probable and possible reserves, anticipated future commodity prices, interest rates, changes in development and production costs and risks associated with future production. Because of these and other considerations, any estimate of fair value is necessarily subjective and imprecise.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
