REDWOOD CITY, Calif., November 2, 2023 — Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company, today announced financial results for the third quarter ended September 30, 2023, and provided a business update.

“Over the past quarter, we have continued to deliver on our plan to reduce our cash burn and put ourselves in an enviable position of financial strength. Our core Pharmaceutical Manufacturing business generates cash, we have a potentially game-changing technology in the ECO Synthesis^™ platform, and, importantly, we have the financial resources to execute on our plans,” said Stephen Dilly, MBBS, PhD, President and Chief Executive Officer of Codexis. “With our current balance sheet, we now expect to fund our planned operations to positive cash flow, which is anticipated around the end of 2026. We look forward to continuing to execute on our key milestones, including the demonstration of gram-scale synthesis with our ECO Synthesis^™ platform by the end of this year.”

Third Quarter and Recent Business Highlights

•

In July 2023, Codexis announced an update to its strategy to focus resources on programs with the strongest probability of creating significant value in the near-term and beyond. Accordingly, the Company is prioritizing the advancement and commercialization of its Enzyme-Catalyzed Oligonucleotide (ECO) Synthesis^™ technology platform, designed to enable the commercial-scale manufacture of RNA interference (RNAi) therapeutics, and its highly complementary Pharmaceutical Manufacturing business. The Company also discontinued investment in certain development programs across Biotherapeutics and Life Sciences, consolidated operations to its headquarters in Redwood City, California and reduced headcount by approximately 25%. These actions enable a potential path to positive cash flow around the end of 2026 based on the Company’s current planned operations.

•

In September 2023, the Company announced it had executed an Assignment and Assumption of Lease for its San Carlos, California location. As a result of consolidating operations, Codexis estimates it will realize cumulative cash savings of more than $30 million through 2031.

•

In September 2023, Dr. Dilly was named winner of the prestigious 2023 Bloom Burton Award, which honors an individual who made the greatest contribution to Canada’s innovative healthcare industry the previous year. Dr. Dilly was recognized for his leadership of Vancouver-headquartered Sierra Oncology, where he led the company through Phase 3 clinical development of momelotinib and its drive toward commercialization up until the company’s $1.9 billion acquisition by GSK.

•

In November 2023, Codexis presented a technical update for its ECO Synthesis^™ platform at the TIDES Europe annual meeting. The presentation focused on the Company’s broader enzyme evolution and process development efforts for both the iterative nucleotide addition and the supply of critical nucleotide reagents. Driving for high volumetric productivity, data highlighted multiple, consecutive additions of 2’-modified RNA nucleotides to a growing oligonucleotide sequence, achieving significant coupling efficiencies with immobilized enzymes. Additionally, proof-of-concept was presented for an enzymatic “one-pot, two-step” phosphorylation cascade to manufacture nucleotide reagents for supply with the ECO Synthesis^™ platform.

Formation of Strategic Advisory Board (SAB) and Key Opinion Leader (KOL) Event on December 8, 2023

•

The Company announced the formation of its SAB, chaired by Codexis Board Member Rahul Singhvi, ScD. This group will play a pivotal role in guiding the Company’s strategic direction and offer valuable insights to inform the continued development of the ECO Synthesis^™ platform. John Maraganore, PhD, founder and former Chief Executive Officer of Alnylam Pharmaceuticals, has joined the SAB as the inaugural external member. Dr. Maraganore is a pioneer in the RNAi therapeutics space, having built and led Alnylam from an early research platform through the global approval and commercialization of the first five RNAi therapeutic medicines.

•

Codexis plans to host an ECO Synthesis^™ platform-focused KOL event at 10:00 am ET on December 8, 2023. In addition to updates from Codexis leadership, the agenda will feature a presentation from John Maraganore. Dr. Maraganore will share his perspective on the role an enzymatic solution like the ECO Synthesis^™ platform would play in the existing RNAi therapeutics manufacturing landscape.

Key Upcoming Milestones

•

The Company expects to achieve gram-scale synthesis with its ECO Synthesis^™ technology platform by the end of 2023, where it will demonstrate the preparative-scale manufacture of an oligoribonucleotide, composed of modified nucleotide building blocks typically used in RNAi therapeutics, under process-like conditions. This critical milestone provides a key point of technical validation to enable pre-commercial customer testing of the platform.

•

Codexis anticipates that the ECO Synthesis^™ platform will enter pre-commercial testing with select customers in 2024. Feedback from this early access program will provide valuable insights and could lead to initial commercial licensing opportunities with those customers in 2025. The full ECO Synthesis^™ platform is expected to be widely available to customers in 2026.

•

The Company anticipates making its newly engineered, double-stranded RNA (dsRNA) ligase widely available for customers in the second half of 2024. As part of Codexis’ initial market entry into the RNAi therapeutics space, the dsRNA ligase is designed to augment and improve traditional phosphoramidite chemistry by stitching together small, manufactured strands of RNA.

Third Quarter 2023 Financial Highlights

•

Total revenues, excluding enzyme sales related to PAXLOVID^™, decreased by 57% to $9.3 million for third quarter 2023 compared to $21.5 million in third quarter 2022. Including enzyme sales related to PAXLOVID^™, total revenues were $9.3 million in third quarter 2023 compared to $34.5 million in third quarter 2022. On a segment basis, $8.7 million in revenue was from the Performance Enzymes segment and $0.6 million was from Biotherapeutics in third quarter 2023.

•

Product revenues, excluding enzyme sales related to PAXLOVID^™, decreased by 64% to $5.4 million for third quarter 2023 compared to $15.1 million in third quarter 2022. Including enzyme sales related to PAXLOVID^™, product revenues were $5.4 million in third quarter 2023 compared to $28.0 million in third quarter 2022.

•

R&D revenues for third quarter 2023 were $3.9 million compared to $6.4 million in third quarter 2022; the decrease was primarily due to lower research and development fees from existing collaboration agreements being recognized in 2023 as compared to the same period in the prior year.

•

Product gross margin, excluding enzyme sales related to PAXLOVID^™, was 58% for third quarter 2023 compared to 55% in third quarter 2022. Including enzyme sales related to PAXLOVID^™, product gross margin for third quarter 2023 was 58% compared to 65% in third quarter 2022; the decrease was largely due to variability in product mix, partially offset by revenue recognized with no related cost in the third quarter of 2023.

•

R&D expenses for third quarter 2023 were $13.7 million compared to $21.8 million in third quarter 2022; the decrease was primarily driven by a decrease in costs associated with lower headcount, lower lab supply costs, lower stock-based compensation costs and a decrease in outside services related to manufacturing and regulatory expenses.

•

Selling, General & Administrative expenses for third quarter 2023 were $12.3 million compared to $13.5 million in third quarter 2022; the decrease was primarily due to lower stock-based compensation costs and fees for outside services.

•

Third quarter 2023 expenses also included one-time restructuring charges of $3.1 million related to the reduction in force announced in July 2023, $9.2 million related to a non-cash impairment charge from the exit of the facility located in San Carlos, California and $0.8 million from a non-cash write-down of goodwill related to the Biotherapeutics segment.

•

Third quarter 2023 other expense included one-time, non-cash impairment charges of $3.9 million related to investments the Company previously made in private life sciences companies.

•

The net loss for third quarter 2023 was $34.9 million, or $0.50 per share, compared to a net loss of $10.0 million, or $0.15 per share, for third quarter 2022. Excluding enzyme sales related to PAXLOVID^™, net loss for third quarter 2022 would have been $20.0 million, or $0.31 per share.

•

Excluding all charges related to the restructuring and impairments, net loss for third quarter 2023 was $17.9 million, or $0.26 per share.

•

As of September 30, 2023, the Company had $74.6 million in cash and cash equivalents. Codexis expects its existing cash and cash equivalents will be sufficient to fund its planned operations to positive cash flow, expected around the end of 2026.
