Organizational changes streamline company and reduce operational expenses

Cash runway extended through 2027

REDWOOD CITY, Calif., Nov. 06, 2025 (GLOBE NEWSWIRE) -- Codexis, Inc. (NASDAQ:CDXS), a leading provider of enzymatic solutions for the efficient and scalable manufacturing of complex therapeutics, today announced financial results for the third quarter ended September 30, 2025. The company also provided a business update that includes signing a $37.8m Supply Assurance Agreement with Merck and organizational changes, together will allow the company to extend its cash runway through 2027.

"We've had a very exciting and important few months that have set us up very well for the changes we are announcing today" said Stephen Dilly, MBBS, PhD, CEO and Chairman at Codexis. "Our ECO Synthesis and ligase businesses have evolved to the point where we are confident of their market potential. We also signed an important agreement with Merck that provides a substantial non-dilutive cash infusion into the company. We feel it is the right time to complete our transition to an innovative manufacturing solutions provider in the field of oligonucleotide manufacturing. We have taken definitive steps to reduce our expenses and focus our efforts on the future businesses of Codexis. This also includes evolving our senior leadership team to prepare for the next phase of Codexis' growth. I am extremely proud to announce that Alison Moore is succeeding me as CEO of Codexis. Alison has been dedicated to Codexis for the last five years as a board member, and the last year, as a member of our executive leadership team. Alison's deep domain experience and leadership skills are a great match for the next stage of our journey. I look forward to continuing my partnership with Alison in my role as Executive Chair of the Board."

"I am honored to be assuming the CEO role at an exciting time in the company's progression," said Alison Moore, PhD, Chief Technology Officer. "Much of my career has involved the development, deployment, and scaling of novel production technologies in various therapeutic areas. I have been fortunate enough to have been part of bringing several advanced medicines, some of which are billion-dollar drugs, to hundreds of thousands of patients. Our ECO Synthesis technology is a powerful production solution which has the potential to truly expand the use of advanced medicines, such as siRNA and other oligonucleotides."

Third Quarter 2025 Financial Highlights

Total revenues were $8.6 million for the third quarter of 2025 compared to $12.8 million in the third quarter of 2024. The decrease was primarily due to variability in customers' manufacturing schedules and clinical trial progression.
Product gross margin was 64% for the third quarter of 2025 compared to 61% in the third quarter of 2024. The increase in gross margin was largely due to a shift in sales toward more profitable products, and declines in less profitable, legacy products.
Research and Development expenses for the third quarter of 2025 were $13.9 million compared to $11.5 million in the third quarter of 2024. The increase was primarily driven by higher headcount, higher lab supplies expense, and the internal reclassification of certain employees to the Research and Development function.
Selling, General & Administrative expenses for the third quarter of 2025 were $11.2 million compared to $13.6 million in the third quarter of 2024. The decrease was primarily due to lower employee-related costs and legal expenses, and reduced use of outside services.

Net loss for the third quarter of 2025 was $19.6 million, or $0.22 per share, compared to a net loss of $20.6 million, or $0.29 per share, for the third quarter of 2024.
As of September 30, 2025, the Company had $58.7 million in cash, cash equivalents and short-term investments.
