Codexis Reports Second Quarter 2026 Financial Results

Reports revenue of $14.9 million for the second quarter of 2026, company reiterates full-year financial guidance

Shared new advances in RNA therapeutic manufacturing at TIDES US showing that its ECO Synthesis^® Manufacturing Platform exerts enzyme-driven stereoisomer control of siRNA

Completed successful equity capital raise of approximately $25 million in net proceeds

REDWOOD CITY, Calif., August 11, 2026 — Codexis, Inc. (NASDAQ: CDXS), a leading provider of enzymatic solutions for efficient and scalable manufacturing of complex therapeutics, today announced financial results for the second quarter ended June 30, 2026, and provided a business update.

“I am pleased with the strong financial results reported today for the second quarter of 2026,” stated Alison Moore, PhD, President and Chief Executive Officer of Codexis. “In May, we presented new data at the TIDES US annual meeting demonstrating how the ECO Synthesis^® Manufacturing Platform enables control over stereochemistry in the manufacture of siRNA compounds which may enhance their potency and product quality. We also demonstrated our technology has the ability to initiate enzymatic RNA synthesis starting from a single nucleotide. In addition, our balance sheet was significantly strengthened by a capital raise of approximately $25 million in net proceeds, completed in July. We have made significant progress in the first half of 2026 in industrializing our ECO Synthesis Manufacturing Platform, and look forward to continued demonstration of the value of our technology to our customers in the second half.”

Second Quarter and Recent Business Highlights

 

•

Codexis hosted three key presentations at the 2026 TIDES US annual meeting that took place in May. These presentations demonstrated enzyme-driven stereoisomer control of siRNA using ECO Synthesis technology, the superior performance of Codexis ligase in siRNA ligation reactions, and the metrics of improved sustainability of the ECO Synthesis manufacturing platform compared to Solid-Phase Oligonucleotide Synthesis, the current industry manufacturing standard. These presentations have generated strong interest in both startup and established participants in the siRNA field.

 

•

The Company successfully completed an equity financing in July that raised a total of approximately $25 million in net proceeds, resulting in proforma cash of approximately $80 million.

Upcoming Milestones

 

•

The Company will be submitting its application for a building permit for its ECO GMP Manufacturing Center in preparation to commence retrofit construction during the second half of 2026. Full production capability is planned by the end of 2027. The purpose of this facility is to provide siRNA material for preclinical investigations and Phase 1 clinical trials.

•

Expand relationships with our CDMO partners with a goal of commencing an additional strategic partnership by the end of 2026.

 

•

Advance our partnerships with drug innovators toward clinical stage manufacturing agreements.

 

•

Continue our engagement with the FDA Emerging Technologies team to discuss ECO Synthesis-derived siRNA product quality, stereoisomer control, and product comparability in anticipation of a meeting with the Agency in the fourth quarter of 2026.

Second Quarter 2026 Financial Highlights

 

•

Total revenues were $14.9 million for the second quarter of 2026 compared to $15.3 million in the second quarter of 2025. The decrease was primarily due to lower research and development revenue. This was mostly offset by higher product revenue, driven by the approval and launch of new products by our customers with higher margins compared to more established products.

 

•

Product gross margin was 73% for the second quarter of 2026, compared to 72% in the second quarter of 2025. The increase in gross margin was largely due to a shift in sales toward more profitable products, and declines in less profitable, established products.

 

•

Research and Development expenses for the second quarter of 2026 were $11.7 million compared to $13.8 million in the second quarter of 2025. The decrease was primarily due to lower employee-related costs, reduced spending on outside services and lower lab supplies, partially offset by higher allocable costs.

 

•

Selling, General & Administrative expenses for the second quarter of 2026 were $10.9 million compared to $12.3 million in the second quarter of 2025. The decrease was primarily due to lower employee-related costs associated with reduced headcount, lower stock-based compensation expenses, and lower allocable costs, partially offset by higher facility-related expenses.

 

•

The net loss for the second quarter of 2026 was $12.0 million, or $0.13 per share, compared to a net loss of $13.3 million, or $0.16 per share, for the second quarter of 2025.

 

•

As of June 30, 2026, Codexis had $54.9 million in cash, cash equivalents, and short-term investments. After the close of the second quarter, Codexis successfully completed an equity financing that raised a total of approximately $25 million in net proceeds, resulting in proforma cash of approximately $80 million.

2026 Financial Guidance Reiterated

Codexis reiterated its full-year 2026 financial guidance as follows:

 

•

Total revenues are expected to be in the range of $72 million to $76 million. Gross margin for the year 2026 is expected to be in the high 60% range.

 

•

Codexis expects that its existing cash, cash equivalents, and short-term investments will be sufficient to fund its planned operations through the end of 2028. The financial guidance and cash runway projections include the expenses associated with the build out of the GMP production facility.
