ROSEVILLE, MN / ACCESSWIRE / May 6, 2021 /Calyxt, Inc.(NASDAQ:CLXT), a plant- based technology company, today announced financial results for its first quarter ended March 31, 2021.

"The first several months of 2021 included several exciting developments in our laboratories, the promotion of Sarah Reiter to Chief Business Officer, and the formation of our Scientific Advisory Board, with the scientific and technical expertise to guide us through the evolution of plant-based technology," said Yves Ribeill, Ph.D., Executive Chair. "We also continued to execute on products in our development pipeline. I am especially pleased that our HOLL soybean received favorable testing results on the fatty acid profile of the product. Also, we successfully transformed the hemp genome, enabling future advancements like trait delivery, gene editing, and advanced plant breeding," noted Dr. Ribeill.

Our key accomplishments include:

Completed preliminary composition analysis that validates Calyxt's next generation soybean product has a high oleic and ultra-low linolenic (HOLL) fatty acid profile that is best-in-class in the premium oil segment. Calyxt intends to partner with elite soybean companies to bring this trait to market as a compelling alternative to commodity soybean and other premium oils.

Calyxt successfully transformed the hemp genome, demonstrating the ability to engineer the hemp genome in a manner that can be used to unlock capabilities in order to selectively breed and deliver improvements in hemp traits. The ability to transform hemp will enable further advancements, including trait delivery, gene editing, and advanced plant breeding, and is expected to accelerate hemp variety development. Calyxt can now deliver traits that benefit both growers and consumers who are increasingly looking for plant-based and sustainable foods, materials, cosmeceuticals, nutraceuticals and more.

Executed new seed sale agreement with an affiliate of a grain customer, a continuation of the relationship established through their purchases of grain.

Sold more than 50 percent of the 2020 grain crop to Archer Daniels Midland (ADM),

with the remaining grain projected to be sold throughout 2021.

Promoted Sarah Reiter to the newly created role of Chief Business Officer, effective May 1, 2021. In this role Ms. Reiter will be responsible for all commercial activities of the company including finding partners for the development and commercialization of our traits and products, and she will also be responsible for communications activities, including corporate communications, public relations, and product marketing.

Appointed world-renownedplant-biochemistry experts to new Scientific Advisory Board (SAB) chaired by Calyxt Co-Founder Dan Voytas, Ph.D. Appointees include Anne Osbourn, Ph.D., Group Leader at the John Innes Center; Elizabeth Sattely, Ph.D., HHMI Investigator and Associate Professor of Chemical Engineering at Stanford University; and Paul Bernasconi, Ph.D., Former Global Function Head for Molecular Biology at BASF Biosciences. The SAB will focus on the identification of high value plant-derived products for development and commercialization using Calyxt's proprietary innovation platform.

• The agronomic and functional quality of our product candidates and the timing of development are subject to a variety of factors and risks, which are described in our filings with the Securities and Exchange Commission.

During the quarter Calyxt stopped development of its improved oil HOLL product, which was being developed with a target of higher HOLL oil content that was intended to reduce costs per pound of oil under its prior go-to-market strategy. During the quarter, Calyxt also determined to pursue trait development and licensing arrangements as its baseline go-to- market strategy. While Calyxt will opportunistically engage in seed sale arrangements, its intention is to license all products under development as traits. Calyxt intends to move its current high oleic soybean product to this go-to-market strategy in 2022 and is currently in

discussions with potential licensors. This transition further reduces Calyxt's capital requirements for these products and is expected to deliver high margin royalty revenue streams when those traits are commercialized by the licensors in future years.

"Our R&D team continues to innovate by identifying and unlocking high value plant-based products and metabolites through the use of Calyxt's proprietary systems and advanced analytics platforms that build upon the learnings from our first edited product," said Dr. Ribeill. "The early-stage validation of Calyxt's best-in-class HOLL marks an exciting development in our ability to quickly discover, understand and harness the potential of complex plant biological pathways to deliver the next generation of plant-based solutions. The successful transformation of the hemp genome is a major accomplishment, and it opens the door for rapid plant breeding advancements that may contribute to the establishment of hemp as a broad acre crop. We look forward to sharing more about these advancements later this year."

First Quarter Financial Highlights

Revenue was $4.4 million in the first quarter of 2021, an increase of $2.0 million, or 85 percent, from the first quarter of 2020. The increase was driven by sales of a portion of the 2020 grain crop as compared to the first quarter of 2020, when we were selling soybean oil and meal. As of March 31, 2021, we had sold over 50 percent of the 2020 grain crop.

Cost of goods sold were $6.7 million in the first quarter of 2021, an increase of $2.9 million, or 74 percent, from the first quarter of 2020. The increase was driven by higher volumes of product sold, higher average prices paid for grain as a result of increases in commodity market prices for soybeans, and $0.2 million of unrealized commodity derivative losses from hedging contracts sold to convert our fixed price grain inventory and fixed price forward purchase contracts to floating prices to link them to market, consistent with how we expect to sell the grain. These increases were partially offset by the benefits resulting from the advancement of our soybean product line go-to- market strategy.

Gross margin was negative $2.3 million, or negative 53 percent, in the first quarter of 2021, compared to negative $1.5 million, or negative 63 percent, in the first quarter of 2020. The decrease was driven by the factors described above with respect to cost of goods sold.

Adjusted gross margin, a non-GAAP measure, was negative $1.3 million, or negative 31 percent, in the first quarter of 2021, compared to negative $1.2 million, or negative 49 percent, in the first quarter of 2020. The improvement on a percentage basis was driven by benefits resulting from the advancement of our soybean product line go-to- market strategy.

See below under the heading "Use of Non-GAAP Financial Information" for a discussion of adjusted gross margin and a reconciliation of gross margin, the most comparable GAAP measure, to adjusted gross margin.

Total operating expenses were $7.3 million in the first quarter of 2021, a decrease of $1.8 million, or 20 percent, from $9.1 million in the first quarter of 2020. The decrease was driven by lower personnel costs as a result of cost reductions following the advancement of the go-to-market strategy for our soybean product line as well as other

reductions in cash expenses from the first quarter of 2020.

Net loss was $10.0 million in the first quarter of 2021, an improvement of $1.0 million, or nine percent, from the first quarter of 2020. The improvement in net loss was driven by $2.7 million of lower non-cash stock compensation expenses as a result of recapture of non-cash stock compensation expense from the forfeiture of unvested stock awards, partially offset by a $2.4 million increase in Section 16 officer transition expenses and a $0.8 million decrease in gross margin. Net loss per share was $0.27 in the first quarter of 2021, an improvement of $0.07 per share, or 21 percent, from the first quarter of 2020. The improvement in net loss per share was driven by the change in net loss.

Adjusted net loss was $8.8 million in the first quarter of 2021, an improvement of $2.0 million, or 18 percent, from the first quarter of 2020. The improvement in adjusted net loss was driven by the benefits resulting from the advancement of our soybean product line go-to-market strategy and other reductions in operating expenses. Adjusted net loss per share was $0.24 in the first quarter of 2021, an improvement of $0.09 per share, or 27 percent, from the first quarter of 2020. The improvement in adjusted net loss per share was driven by the change in adjusted net loss.

See below under the heading "Use of Non-GAAP Financial Information" for a discussion of adjusted net loss and adjusted net loss per share, and reconciliations of net loss and net loss per share, the most comparable GAAP measures, to adjusted net loss and adjusted net loss per share.

Adjusted EBITDA loss was $6.8 million in the first quarter of 2021, an improvement of $1.4 million, or 17 percent, from the first quarter of 2020. The improvement was driven by the benefits resulting from the advancement of our soybean product line go-to- market strategy and other reductions in operating expenses.

See below under the heading "Use of Non-GAAP Financial Information" for a discussion of adjusted EBITDA and a reconciliation of net loss, the most comparable GAAP measure, to adjusted EBITDA.

Net cash used was $0.9 million in the first quarter of 2021, an improvement of $50.3 million, from net cash used of $ 51.2 million in the first quarter of 2020. The improvement was driven by changes in purchases and sales of short-term investments of $47.3 million and a $2.8 million improvement in net cash used by operating activities, primarily the result of the improvements in net loss and working capital. In the first quarter of 2020, Calyxt invested cash and cash equivalents in short-term investments to diversify counterparty credit risk.

Cash, cash equivalents, short-term investments, and restricted cash totaled $20.4 million as of March 31, 2021.

CFO Summary

"From a cash perspective, the first quarter of 2021 was highlighted by the significant progress we made selling grain, managing grower deliveries to best match demand, and reducing operating expenses below last year and staying on track to achieve our cash operating expense annual target of $25 million or less. We believe these actions will be enough to fund our operations for at least the next twelve months and into the second half of 2022," said Bill Koschak, Calyxt Chief Financial Officer.
