Roseville, MN – August 4, 2022 – Calyxt, Inc. (Nasdaq: CLXT), a plant-based synthetic biology company, today announced financial results for its second quarter ended June 30, 2022.

“Throughout the second quarter of 2022, the Calyxt team tangibly advanced our business and related milestones. We are very pleased to be discussing term sheets for the development and production of chemistries with potential customers in our large and innovative initial target end markets. Calyxt’s progress is evidenced by the 95 customer demand-driven chemistries we have evaluated for development for potential customers, up from 86 at the end of last quarter. Chemistries identified by customers are screened and prioritized by Calyxt to focus on those with the highest probability of success. In terms of our infrastructure partner milestones, we are in discussions with several companies with capabilities to manufacture multiple chemistries concurrently from pilot to multiple commercial scale vessels on a global basis. Also importantly, we are evaluating multiple term sheets for technology licensing and for the licensing of traits, reflecting significant interest in our second-generation high oleic soybean and high fiber wheat offerings. Throughout the quarter we also continued to work on scaling and standardizing our production in our pilot BioFactory system and building out our AIML capabilities. We are proud of the significant progress we have made in a short period of time, and it is a testament to our new strategic direction gaining traction. We continue our focused drive to realize value for our stakeholders and look forward to providing updates in the coming months,” said Michael A. Carr, President and Chief Executive Officer at Calyxt.

Mr. Carr added: “The state of our discussions with potential infrastructure partners advanced during the quarter, offering a foundation to support the scalability of large customers in our key end markets. These advancements potentially accelerate Calyxt forward in terms of the speed at which we could bring our chemistries to said customers. The feedback we have thus far received from these infrastructure partners is that they understand and appreciate that Calyxt is going after hard-to-solve chemistries that are high-value and potentially high-margin. Importantly, Calyxt’s progress with these infrastructure partners not only supports future deals, but also brings value to ongoing customer conversations.”

Multiple Term Sheets for Licensing of Technology and Traits under Evaluation

“Late last year, we announced the strategic hire of Pete Ball as Technology Licensing Leader. He has been leading our licensing business, including technology and traits, and Calyxt has since made substantial progress in discussions with potential licensees in this area. It is clear these potential licensees see the value of our offerings, especially in these times of global supply issues and food insecurity. We continue our focused drive to realize value for our stakeholders and look forward to providing updates in the coming months,” Mr. Carr continued.

About the PlantSpring^™ Technology Platform and BioFactory^™ Production System

Calyxt’s technology platform, PlantSpring, is founded on the Company’s more than a decade of experience engineering plant metabolism, and incorporates its scientific knowledge, its proprietary systems, tools, and technologies; and an expanding set of related capabilities. In PlantSpring, the Company identifies metabolic pathways to produce plant-based chemistries, designs strategies to reprogram host cells, engineers plant cell metabolism to optimally produce targeted compounds, and produces those targeted compounds at laboratory scale. The Company has implemented AIML capabilities for the identification of targets for editing specific genetic pathways and continues to develop AIML capabilities across the PlantSpring platform, which will enable learning and adaptation of knowledge gained from past activity and are expected to be combined with predictive analytics to rapidly prototype and provide feedback, accelerate the time to complete the development cycle and help mitigate the risk associated with commercial scale-up. As a result, Calyxt believes it can develop biomolecules in plants for customers at both a greater breadth and level of complexity and at faster speeds than its competitors in the synthetic biology industry. The output from the PlantSpring platform integrates with the Company’s BioFactory production system. The Company uses the term “compounds” to describe compounds, molecules, and plant-based chemistries interchangeably.

The BioFactory is a bioreactor-based production system that is designed to be capable of continuous production of plant-based chemistries. The bioreactor can be of any size depending upon factors including yield and titer necessary to reach the required commercial scale. For production, multicellular Plant Cell Matrix^™ (PCM^™) structures are placed inside the bioreactor, and growth media bathes the PCM structures to provide them with nutrition, which differentiates the Company’s process from other methods that require complete submersion of cells in growth media and/or the application of hormones to facilitate growth. A PCM structure is a living system of various cell types, which is designed to emulate the intercellular metabolism of an entire plant, which grows over time, produces, and stores, or excretes, the target chemistries. The growth media is the feedstock of the BioFactory production system and contains the essential inputs to support growth of the PCM structures and necessary chemistry production. The growth media is expected to be reused throughout the production cycle, which may run for an extended time period. To scale production in the BioFactory productions system, the Company expects to move the PCM structures from its current bioreactor into larger capacity bioreactors or groups of bioreactors. Calyxt began running lab-scale bioreactors in early 2021. The Company’s first pilot-scale bioreactor became operational in December 2021 and is scalable up to 200 liters. The pilot stage of development takes a compound developed with the PlantSpring platform through to commercial production. Depending on the compound to be produced, there may be a range of vessel sizes between the initial pilot facility and the commercial production facility. The Company’s current plan is to engage third parties, referred to as infrastructure partners, for at-scale commercial production. Infrastructure partners are likely to be companies with processing assets that can be converted from current production to the Company’s bioreactor-based approach. If an infrastructure partner is used for production, the Company expects to pay a fee for that production. Because of the expected modular nature of the BioFactory production system and the types of high value compounds the Company expects to develop for customers, it is also possible that commercial production could also occur in a customer’s in-house facility. The Company expects to expand the scope of its pilot facilities based on customer demand, and the scope of production could extend, subject to regulatory and other considerations, outside the United States. Because of its production methodology, Calyxt believes the BioFactory has the potential to be one of the most sustainable production systems across industries.

USE OF NON-GAAP FINANCIAL INFORMATION

To supplement the Company’s financial results prepared in accordance with GAAP, it has prepared certain non-GAAP measures that include or exclude special items. These non-GAAP measures are not meant to be considered in isolation or as a substitute for financial information presented in accordance with GAAP and should be viewed as supplemental and in addition to the Company’s financial information presented in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures. In addition, other companies may report similarly titled measures, but calculate them differently, which reduces their usefulness as a comparative measure. Management utilizes these non-GAAP metrics as performance measures in evaluating and making operational decisions regarding the Company’s business.

The Company’s 2021 non-GAAP financial measures reflect adjustments for certain commodity derivatives entered into in connection with its soybean product line. As a result of the completed wind-down of this product line in late 2021, the Company held no commodity derivative contracts as of June 30, 2022.

The Company presents adjusted net loss, a non-GAAP measure, and defines it as net loss adjusted for (i) unrealized gains and losses associated with commodity derivatives entered into to hedge the change in value of fixed price grain inventories and fixed price grain production agreements that should be recognized in the future when the underlying inventory is sold, (ii) gains and losses from commodity derivatives realized in prior periods but associated with inventory sold in the current period, (iii) net realizable value adjustments to inventories occurring in the period which otherwise would have been recognized in the future when the underlying inventory is sold, and (iv) net realizable value adjustments recognized in prior periods but associated with inventory sold in the current period, and excluding cash-based Section 16 officer transition expenses, the recapture of non-cash stock compensation associated with the departure of Section 16 officers, the gain upon the extinguishment of the Payroll Protection Program (PPP) loan, and non-operating income (expenses). The foregoing adjustments are those necessary to present the underlying gross profit of the Company’s soybean product line for the 2021 periods presented, together with the corresponding adjustments to the extent applicable to the corresponding 2022 periods presented.

The Company provides in the table below a reconciliation of net loss, which is the most directly comparable GAAP financial measure, to adjusted net loss. The Company provides adjusted net loss because it believes that this non-GAAP financial metric provides investors with useful supplemental information in light of the Company’s business model during the periods presented as the amounts being adjusted affect the period-to-period comparability of net losses and financial performance.

The table below presents a reconciliation of net loss to adjusted net loss:

The Company presents adjusted net loss per share, a non-GAAP measure, and defines it as net loss per share adjusted for (i) unrealized gains and losses associated with commodity derivatives entered into to hedge the change in value of fixed price grain inventories and fixed price grain production agreements that should be recognized in the future when the underlying inventory is sold, (ii) gains and losses from commodity derivatives realized in prior periods but associated with inventory sold in the current period, (iii) net realizable value adjustments to inventories occurring in the period which otherwise would have been recognized in the future when the underlying inventory is sold, and (iv) net realizable value adjustments recognized in prior periods but associated with inventory sold in the current period, and excluding cash-based Section 16 officer transition expenses, the recapture of non-cash stock compensation associated with the departure of Section 16 officers, the gain upon the extinguishment of the PPP loan, and non-operating income (expenses). The foregoing adjustments are those necessary to present the underlying gross profit of the Company’s soybean product line for the 2021 periods presented, together with the corresponding adjustments to the extent applicable to the corresponding 2022 periods presented.
