HOUSTON, Oct. 17, 2018 (GLOBE NEWSWIRE) -- Crown Castle International Corp. (NYSE: CCI) ("Crown Castle") today reported results for the quarter ended September 30, 2018.

2019 Outlook for Organic Contribution to Site Rental Revenues, Growth in Site Rental Revenues ($ in millions) 2019 Outlook for AFFO growth ($ in millions)

"We delivered another terrific quarter of results in the third quarter and increased our annualized common stock dividend by 7% to $4.50 per share based on accelerating leasing activity," stated Jay Brown, Crown Castle's Chief Executive Officer. "Over the past two decades, we have built and acquired an unmatched portfolio of more than 40,000 towers and 65,000 route miles of dense, high capacity fiber in the top U.S. markets, where we see the greatest long-term demand from multiple customers. We believe our ability to offer towers, small cells and fiber solutions, which are all integral components of communications networks and are shared among multiple tenants, provides us the best opportunity to generate significant growth while delivering high returns for our shareholders. Further, we believe that the U.S. represents the best market in the world for communications infrastructure ownership and we are pursuing that compelling opportunity with our comprehensive offering. With the positive momentum we continue to see in our towers and fiber segments, we remain dedicated to investing in our business to generate future growth while delivering dividend per share growth of 7% to 8% per year."

HIGHLIGHTS FROM THE QUARTER

• Site rental revenues. Site rental revenues grew approximately 33%, or $291 million, from third quarter 2017 to third quarter 2018, inclusive of approximately $52 million in Organic Contribution to Site Rental Revenues plus $219 million in contributions from acquisitions and other items, plus a $20 million increase in straight-lined revenues. The $52 million in Organic Contribution to Site Rental Revenues represents approximately 5.8% growth, comprised of approximately 8.4% growth from new leasing activity and contracted tenant escalations, net of approximately 2.6% from tenant non-renewals. When compared to the prior third quarter 2018 Outlook, site rental revenues benefited by approximately $3 million of additional straight-lined revenues primarily resulting from term extensions associated with leasing activity.
• Net income. Net income for third quarter 2018 was $164 million, compared to $115 million during the same period a year ago.
• Adjusted EBITDA. When compared to the third quarter 2018 Outlook, Adjusted EBITDA benefited by approximately $3 million of additional straight-lined revenues, offset by approximately $2 million of additional straight-lined expenses.
• AFFO. When compared to the third quarter 2018 Outlook, AFFO benefited by approximately $3 million related to certain sustaining capital expenditures that did not occur during the third quarter and are now expected to occur during the fourth quarter.
• Capital expenditures. Capital expenditures during the quarter were $478 million, comprised of $14 million of land purchases, $27 million of sustaining capital expenditures, $436 million of revenue generating capital expenditures and $1 million of integration capital expenditures.
• Common stock dividend. During the quarter, Crown Castle paid common stock dividends of $1.05 per common share, an increase of approximately 11% compared to the same period a year ago.
• Financing activities. In July, Crown Castle issued $1.0 billion of Senior Secured Tower Revenue Notes with net proceeds from the offering and cash on hand used to retire $1.0 billion of existing Senior Secured Tower Revenue Notes.

"The solid third quarter results reflect the strength of our business model and our ability to leverage our leadership position in the U.S. across towers, small cells and fiber solutions to generate growth," stated Dan Schlanger, Crown Castle's Chief Financial Officer. "As we focus on closing out 2018 and look towards 2019, we are excited about all of the positive trends creating increasing demand for our tower, small cell and fiber assets. We believe we are in a great position to continue to deliver on our growth targets and invest for the future while returning capital to our shareholders through a high quality and growing dividend. Since 2014, and inclusive of the dividend increase we are announcing today, we have increased our dividend by a compounded annual growth rate of approximately 8%, and we believe we are well positioned to deliver on our 7% to 8% long-term annual dividend growth target going forward."

DIVIDEND INCREASE ANNOUNCEMENTCrown Castle's Board of Directors has declared a quarterly cash dividend of $1.125 per common share, representing an increase of 7% over the previous quarterly dividend of $1.05 per share. The quarterly dividend will be payable on December 31, 2018 to common stockholders of record at the close of business on December 14, 2018. Future dividends are subject to the approval of Crown Castle's Board of Directors.

• New leasing activity is expected to contribute $350 million to $380 million to 2019 Organic Contribution to Site Rental Revenues, consisting of new leasing activity from towers of $120 million to $130 million, small cells of $70 million to $80 million, and fiber solutions of $160 million to $170 million.
• The chart below reconciles the components of expected growth in AFFO from 2018 to 2019 of $135 million to $180 million.

A photo accompanying this announcement is available at http://www.globenewswire.com/NewsRoom/AttachmentNg/5f742149-932c-45b8-ad87-d4a441239b28

• The expected increase in expenses from 2018 to 2019 of approximately $80 million at the midpoint reflects a combination of the typical cost escalations and the direct expenses associated with accelerating new leasing activity.
• The expected change in network services contribution in 2019 of approximately $25 million at the midpoint reflects the higher expected new leasing activity from towers in 2019.
• In addition, the expected growth in AFFO from 2018 to 2019 is impacted by approximately $70 million of higher financing costs, inclusive of approximately $25 million that is related to higher expected average floating interest rates in 2019 when compared to average rates in 2018, as well as approximately $45 million that is related to funding our discretionary capital expenditures.
• Additional information is available in Crown Castle's quarterly Supplemental Information Package posted in the Investors section of its website.

Non-GAAP Financial Measures, Segment Measures and Other Calculations

This press release includes presentations of Adjusted EBITDA, Adjusted Funds from Operations ("AFFO"), Funds from Operations ("FFO") and Organic Contribution to Site Rental Revenues, which are non-GAAP financial measures. These non-GAAP financial measures are not intended as alternative measures of operating results or cash flow from operations (as determined in accordance with Generally Accepted Accounting Principles ("GAAP")).

Our measures of Adjusted EBITDA, AFFO, FFO and Organic Contribution to Site Rental Revenues may not be comparable to similarly titled measures of other companies, including other companies in the communications infrastructure sector or other real estate investment trusts ("REITs"). Our definition of FFO is consistent with guidelines from the National Association of Real Estate Investment Trusts with the exception of the impact of income taxes in periods prior to our REIT conversion in 2014.

In addition to the non-GAAP financial measures used herein, we also provide Segment Site Rental Gross Margin, Segment Network Services and Other Gross Margin and Segment Operating Profit, which are key measures used by management to evaluate our operating segments for purposes of making decisions about allocating capital and assessing performance. These segment measures are provided pursuant to GAAP requirements related to segment reporting. In addition, we provide the components of certain GAAP measures, such as capital expenditures.

Adjusted EBITDA, AFFO, FFO and Organic Contribution to Site Rental Revenues are presented as additional information because management believes these measures are useful indicators of the financial performance of our business. Among other things, management believes that:

• Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance. Adjusted EBITDA is the primary measure used by management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations. Management believes that Adjusted EBITDA helps investors or other interested parties meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors, by removing the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results. Management also believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation of the communications infrastructure sector and other REITs to measure financial performance without regard to items such as depreciation, amortization and accretion which can vary depending upon accounting methods and the book value of assets. In addition, Adjusted EBITDA is similar to the measure of current financial performance generally used in our debt covenant calculations. Adjusted EBITDA should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
• AFFO is useful to investors or other interested parties in evaluating our financial performance. Management believes that AFFO helps investors or other interested parties meaningfully evaluate our financial performance as it includes (1) the impact of our capital structure (primarily interest expense on our outstanding debt and dividends on our preferred stock) and (2) sustaining capital expenditures, and excludes the impact of our (a) asset base (primarily depreciation, amortization and accretion) and (b) certain non-cash items, including straight-lined revenues and expenses related to fixed escalations and rent free periods. GAAP requires rental revenues and expenses related to leases that contain specified rental increases over the life of the lease to be recognized evenly over the life of the lease. In accordance with GAAP, if payment terms call for fixed escalations, or rent free periods, the revenue or expense is recognized on a straight-lined basis over the fixed, non-cancelable term of the contract. Management notes that Crown Castle uses AFFO only as a performance measure. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flows from operations or as residual cash flow available for discretionary investment.
• FFO is useful to investors or other interested parties in evaluating our financial performance. Management believes that FFO may be used by investors or other interested parties as a basis to compare our financial performance with that of other REITs. FFO helps investors or other interested parties meaningfully evaluate financial performance by excluding the impact of our asset base (primarily depreciation, amortization and accretion). FFO is not a key performance indicator used by Crown Castle. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flow from operations.
• Organic Contribution to Site Rental Revenues is useful to investors or other interested parties in understanding the components of the year-over-year changes in our site rental revenues computed in accordance with GAAP. Management uses the Organic Contribution to Site Rental Revenues to assess year-over-year growth rates for our rental activities, to evaluate current performance, to capture trends in rental rates, new leasing activities and customer non-renewals in our core business, as well to forecast future results. Organic Contribution to Site Rental Revenues is not meant as an alternative measure of revenue and should be considered only as a supplement in understanding and assessing the performance of our site rental revenues computed in accordance with GAAP.

We define our non-GAAP financial measures, segment measures and other calculations as follows:

Non-GAAP Financial Measures

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) plus restructuring charges (credits), asset write-down charges, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-sale securities, interest income, other (income) expense, (benefit) provision for income taxes, cumulative effect of a change in accounting principle, (income) loss from discontinued operations and stock-based compensation expense.

Adjusted Funds from Operations. We define Adjusted Funds from Operations as FFO before straight-lined revenue, straight-lined expense, stock-based compensation expense, non-cash portion of tax provision, non-real estate related depreciation, amortization and accretion, amortization of non-cash interest expense, other (income) expense, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, acquisition and integration costs, and adjustments for noncontrolling interests, and less sustaining capital expenditures (comprised of capital improvement capital expenditures and corporate capital expenditures).

Funds from Operations. We define Funds from Operations as net income plus real estate related depreciation, amortization and accretion and asset write-down charges, less noncontrolling interest and cash paid for preferred stock dividends, and is a measure of funds from operations attributable to CCIC common stockholders.

Organic Contribution to Site Rental Revenues. We define the Organic Contribution to Site Rental Revenues as the sum of the change in GAAP site rental revenues related to (1) new leasing activity, including revenues from the construction of small cells and the impact of prepaid rent, (2) escalators and less (3) non-renewals of customer contracts.

Segment Measures

Segment Site Rental Gross Margin. We define Segment Site Rental Gross Margin as segment site rental revenues less segment site rental cost of operations, excluding stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated site rental cost of operations.

Segment Network Services and Other Gross Margin. We define Segment Network Services and Other Gross Margin as segment network services and other revenues less segment network services and other cost of operations, excluding stock-based compensation expense recorded in consolidated network services and other cost of operations.

Segment Operating Profit. We define Segment Operating Profit as segment site rental gross margin plus segment network services and other gross margin, less selling, general and administrative expenses attributable to the respective segment.

All of these measurements of profit or loss are exclusive of depreciation, amortization and accretion, which are shown separately.

Other Calculations

Discretionary capital expenditures. We define discretionary capital expenditures as those capital expenditures made with respect to activities which we believe exhibit sufficient potential to enhance long-term stockholder value. They consist of expansion or development of existing communications infrastructure, construction of new communications infrastructure, and, to a lesser extent, purchases of land interests (which primarily relate to land assets under towers as we seek to manage our interests in the land beneath our towers) and other capital projects.

Sustaining capital expenditures. We define sustaining capital expenditures as those capital expenditures made with respect to either (1) corporate capital expenditures or (2) capital improvement capital expenditures on our communications infrastructure assets that enable our customers' ongoing quiet enjoyment of the communications infrastructure.

Integration capital expenditures. We define integration capital expenditures as those capital expenditures made specifically with respect to acquisitions that are essential to integrating acquired companies into our business.

The tables set forth below reconcile the non-GAAP financial measures used herein to comparable GAAP financial measures. The components in these tables may not sum to the total due to rounding. The Company has changed its presentation to millions and, as a result, any necessary rounding adjustments have been made to prior year disclosed amounts.

Cautionary Language Regarding Forward-Looking Statements

This press release contains forward-looking statements and information that are based on our management's current expectations. Such statements include our Outlook and plans, projections, and estimates regarding (1) potential benefits, returns, opportunities and customer and shareholder value which may be derived from our business, assets, investments, acquisitions and dividends, including on a long-and short-term basis, (2) our strategy, strategic position, business model and capabilities and the strength of our business, (3) our growth, including growth in our cash flows and dividends per share, long-term prospects and the trends impacting our business, (4) the potential benefits and contributions which may be derived from our recent acquisitions, including the contribution to or impact on our financial or operating results, (5) leasing environment and activity, including the contribution to our financial or operating results therefrom, (6) our investments in our business and communications infrastructure assets and the potential growth, returns and benefits therefrom, (7) our dividends and our dividend growth rate, including its driving factors, and targets, (8) our portfolio of assets, including demand therefor, strategic position thereof and opportunities created thereby, (9) financing costs and the impact of the anticipated increase in average floating interest rates thereon, (10) cash flows, (11) tenant non-renewals, including the impact thereof, (12) capital expenditures, including sustaining and discretionary capital expenditures, (13) straight-line adjustments, (14) site rental revenues and estimated growth thereof, (15) site rental cost of operations, (16) net income (loss), (17) Adjusted EBITDA, including the impact thereon of timing items, (18) expenses, including repair and maintenance expense and interest expense and amortization of deferred financing costs, (19) FFO, (20) AFFO and estimated growth thereof, (21) Organic Contribution to Site Rental Revenues, (22) our weighted-average common shares outstanding, including on a diluted basis, (23) network services contribution and (24) the utility of certain financial measures, including non-GAAP financial measures. Such forward-looking statements are subject to certain risks, uncertainties and assumptions prevailing market conditions and the following:

• Our business depends on the demand for our communications infrastructure, driven primarily by demand for data, and we may be adversely affected by any slowdown in such demand. Additionally, a reduction in the amount or change in the mix of network investment by our customers may materially and adversely affect our business (including reducing demand for tenant additions and network services).
• A substantial portion of our revenues is derived from a small number of customers, and the loss, consolidation or financial instability of any of such customers may materially decrease revenues or reduce demand for our communications infrastructure and network services.
• The expansion or development of our business, including through acquisitions, increased product offerings or other strategic growth opportunities may cause disruptions in our business, which may have an adverse effect on our business, operations or financial results. Additionally, we may fail to realize all of the anticipated benefits of the Lightower acquisition, or those benefits may take longer to realize than expected.
• Our fiber segment has expanded rapidly, and the fiber business model contains certain differences from our towers business model, resulting in different operational risks. If we do not successfully operate our Fiber business model or identify or manage the related operational risks, such operations may produce results that are less than anticipated.
• Failure to timely and efficiently execute on our construction projects could adversely affect our business.
• Our substantial level of indebtedness could adversely affect our ability to react to changes in our business, and the terms of our debt instruments and our 6.875% Mandatory Convertible Preferred Stock limit our ability to take a number of actions that our management might otherwise believe to be in our best interests. In addition, if we fail to comply with our covenants, our debt could be accelerated.
• We have a substantial amount of indebtedness. In the event we do not repay or refinance such indebtedness, we could face substantial liquidity issues and might be required to issue equity securities or securities convertible into equity securities, or sell some of our assets to meet our debt payment obligations.
• Sales or issuances of a substantial number of shares of our common stock or securities convertible into shares of our common stock may adversely affect the market price of our common stock.
• As a result of competition in our industry, we may find it more difficult to negotiate favorable rates on our new or renewing tenant contracts.
• New technologies may reduce demand for our communications infrastructure or negatively impact our revenues.
• If we fail to retain rights to our communications infrastructure, including the land interests under our towers and the right-of-way and other agreements related to our small cells and fiber solutions, our business may be adversely affected.
• Our network services business has historically experienced significant volatility in demand, which reduces the predictability of our results.
• New wireless technologies may not deploy or be adopted by customers as rapidly or in the manner projected.
• If we fail to comply with laws or regulations which regulate our business and which may change at any time, we may be fined or even lose our right to conduct some of our business.
• If radio frequency emissions from wireless handsets or equipment on our communications infrastructure are demonstrated to cause negative health effects, potential future claims could adversely affect our operations, costs or revenues.
• Certain provisions of our restated certificate of incorporation, amended and restated by-laws and operative agreements, and domestic and international competition laws may make it more difficult for a third party to acquire control of us or for us to acquire control of a third party, even if such a change in control would be beneficial to our stockholders.
• We may be vulnerable to security breaches that could adversely affect our business, operations, and reputation.
• Future dividend payments to our stockholders will reduce the availability of our cash on hand available to fund future discretionary investments, and may result in a need to incur indebtedness or issue equity securities to fund growth opportunities. In such event, the then current economic, credit market or equity market conditions will impact the availability or cost of such financing, which may hinder our ability to grow our per share results of operations.
• Remaining qualified to be taxed as a REIT involves highly technical and complex provisions of the U.S. Internal Revenue Code. Failure to remain qualified as a REIT would result in our inability to deduct dividends to stockholders when computing our taxable income, which would reduce our available cash.
• If we fail to pay scheduled dividends on our 6.875% Mandatory Convertible Preferred Stock, in cash, common stock, or any combination of cash and common stock, we will be prohibited from paying dividends on our common stock, which may jeopardize our status as a REIT.
• Complying with REIT requirements, including the 90% distribution requirement, may limit our flexibility or cause us to forgo otherwise attractive opportunities, including certain discretionary investments and potential financing alternatives.
• REIT related ownership limitations and transfer restrictions may prevent or restrict certain transfers of our capital stock.

Should one or more of these or other risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those expected. More information about potential risk factors which could affect our results is included in our filings with the SEC. As used in this release, the term "including," and any variation thereof, means "including without limitation."
