Codexis Reports Second Quarter 2024 Financial Results

Company Reiterates Full-year Financial Guidance; On Track to Achieve Product Revenue Growth of at Least 10% vs. FY2023 Excluding Enzyme Sales Related to PAXLOVID™

Anticipate Entering First Technical Collaboration for ECO Synthesis™ Manufacturing Platform by End of Year

REDWOOD CITY, Calif., August 8, 2024 -- Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company, today announced financial results for the second quarter ended June 30, 2024, and provided a business update.

“We’re pleased that our second quarter revenues are exactly in-line with our expectations. As a result, we are reiterating our 2024 financial guidance and look forward to a strong second half of the year, including fulfilling the first order for our double-stranded RNA ligase. We are confident that we remain on track to deliver double-digit year-over-year revenue growth,” said Stephen Dilly, MBBS, PhD, Chief Executive Officer at Codexis. “Additionally, our technical progress has been faster than expected. Our groundbreaking TIDES USA presentation demonstrating the enzymatic synthesis of a full-length siRNA oligonucleotide is unprecedented. Finally, discussions with multiple potential partners are active and proceeding well and we anticipate entering our first technical collaboration for the ECO Synthesis™ manufacturing platform before year-end.”

Second Quarter and Recent Business Highlights

•At the TIDES USA annual meeting in May 2024, Codexis presented groundbreaking enzymatic synthesis data from its ECO Synthesis™ technology platform to support RNA-based therapeutics manufacturing. During a Spotlight Presentation, the Company announced it had synthesized the full-length, sense strand oligonucleotide of the siRNA therapeutic lumasiran via its enzymatic route. In the manufacturing of this commercially available oligonucleotide—as well as shorter sense strand fragments of a second siRNA therapeutic asset, givosiran—Codexis consistently achieved coupling efficiency greater than 98%, which is equivalent to what is seen with phosphoramidite chemistry; executed the enzymatic addition of a conjugation moiety to the lumasiran strand; and confirmed the lack of notable impurities typically observed in oligonucleotide synthesis via phosphoramidite chemistry. A recording of the presentation, along with slides and the data press release, can be found on the Codexis corporate website.

•Also at the 2024 TIDES USA annual meeting, Codexis launched its double-stranded RNA (dsRNA) ligase screening and optimization services. The dsRNA ligase program is designed to augment and improve traditional phosphoramidite chemistry by stitching together small, manufactured strands of RNA. In addition to enabling the more efficient use of existing chemical synthesis with the potential to reduce overall costs, the dsRNA ligase provides an opportunity to educate potential customers on the benefits of incorporating enzymatic solutions as a complement to their current manufacturing processes. The Company has already received a low-to-mid-single-digit million-dollar order for its dsRNA ligase from a large pharmaceutical customer.

•In July 2024, the Company further strengthened its commercial leadership with the appointment of Britton Jimenez to Senior Vice President, Commercial Operations, reporting to Kevin Norrett, Chief Operating Officer. Mr. Jimenez brings more than 20 years’ experience with Contract Development and Manufacturing Organizations to Codexis, which will provide valuable insights as we position Codexis for our next phase of growth.

•Codexis announced in July 2024 that the Company had finalized a purchase agreement with Crosswalk Therapeutics for two gene therapy assets. Under the terms of the agreement, Crosswalk acquired the Company’s investigational Fabry and Pompe disease compounds, and Codexis is eligible to receive future development and commercial milestone payments in addition to a low-to-mid single-digit percentage net sales-based royalty. Both programs were previously part of Codexis’ collaboration agreement with Takeda. In April 2023, Takeda discontinued its efforts in adeno-associated virus (AAV) gene therapy, which included these development programs.

Upcoming Milestones for Second Half 2024

•Codexis continues to expect to enter its first technical collaboration with the ECO Synthesis™ manufacturing platform by the end of 2024.

•The Company expects to complete the build-out of its ECO Synthesis™ Innovation Lab around the end of 2024.

2024 Financial Guidance Reiterated

Codexis reiterated its full-year 2024 financial guidance originally issued on February 28, 2024, as follows:

•Product revenues are expected to be in the range of $38 million to $42 million, excluding revenue related to PAXLOVID™.

•R&D revenues are expected to be in the range of $18 million to $22 million.

•Gross margin on product revenue is expected to be in the range of 58% to 63%, excluding revenue related to PAXLOVID™.

Second Quarter 2024 Financial Highlights

•As of June 30, 2024, the Company had $73.2 million in cash, cash equivalents and short-term investments, which is expected to fund planned operations through positive cash flow, anticipated around the end of 2026.

•Product and R&D revenues for the second quarter 2024 were in-line with guidance provided during the Company’s Q1 2024 financial results call. Total revenues were $8.0 million for second quarter 2024 compared to $21.3 million in second quarter 2023. Product revenues were $6.3 million for second quarter 2024 compared to $11.0 million in second quarter 2023, driven by timing of customer orders. R&D revenues for second quarter 2024 were $1.7 million compared to $10.3 million in second quarter 2023; the decrease was primarily due to lower non-recurring items, including for Biotherapeutics programs that the Company previously discontinued and a one-time, non-cash license fee.

•Product gross margin was 45% for second quarter 2024 compared to 71% in second quarter 2023. The decline in gross margin was largely due to variability in the product mix.

•R&D expenses for second quarter 2024 were $11.4 million compared to $17.3 million in second quarter 2023; the decrease was primarily driven by a decrease in costs associated with lower headcount, lower use of outside services related to Chemistry, Manufacturing and Controls and lower regulatory expenses, a decrease in lease and facilities costs due to the assignment of the Company’s San Carlos facility lease during the fourth quarter of 2023, and lower stock-based compensation costs.

•Selling, General & Administrative expenses for second quarter 2024 were $15.7 million compared to $13.4 million in second quarter 2023; the increase was primarily due to higher stock-based

compensation expense, including a one-time, non-cash modification expense of $2 million, and an increase in facilities associated costs, partially offset by a decrease in costs associated with lower headcount.

•The net loss for second quarter 2024 was $22.8 million, or $0.32 per share, compared to a net loss of $11.5 million, or $0.17 per share, for second quarter 2023.
