Codexis (CDXS) Q3 2025: Eco Platform Contracts Jump to 11, Accelerating Oligonucleotide Manufacturing Pivot
Codexis’s strategic shift toward oligonucleotide manufacturing is crystallizing, with 11 Eco platform contracts now signed and a major Merck supply deal providing critical non-dilutive funding. Leadership transition and cost restructuring are designed to streamline the business for this new phase, as legacy enzyme sales take a back seat to scaled siRNA production. Investors should watch for execution on facility buildout and expanded service revenues as Codexis targets a runway through 2027.
Summary
- Eco Platform Momentum: Commercial focus pivots to oligonucleotide manufacturing with 11 active contracts and 40 more in pipeline.
- Cost Base Reset: Headcount reductions and refocused sales effort aim to cut burn by 25 percent and extend cash runway.
- Leadership and Execution Shift: New CEO with deep technical expertise signals intensified push on scaling and operational delivery.
Performance Analysis
Codexis reported total revenue of $8.6 million for Q3 2025, down from $12.8 million in the prior year period, primarily reflecting timing variability in customer manufacturing schedules and clinical trial progress. Despite the top-line contraction, product gross margin improved to 64 percent from 61 percent, driven by a favorable shift toward higher-margin Eco platform and ligase service contracts and away from legacy enzyme products.
Research and development expenses rose to $13.9 million, reflecting higher headcount and increased lab supply costs as Codexis invests in scaling its Eco platform for oligonucleotide manufacturing. Meanwhile, selling, general, and administrative costs fell to $11.2 million due to workforce reductions and lower legal and external service spend. The company posted a net loss of $19.6 million, a modest improvement from $20.6 million last year, and ended the quarter with $58.7 million in cash, not yet including proceeds from the Merck agreement.
- Eco Platform Revenue Shift: Service contracts now dominate new business, offsetting legacy enzyme declines.
- Margin Expansion: Higher-margin product mix and cost discipline support gross margin gains despite revenue drop.
- Cash Runway Extension: Merck supply deal and cost cuts extend funding through 2027, reducing capital risk.
The financial narrative is one of transition: Codexis is absorbing near-term revenue softness as it reallocates resources to higher-value, scalable manufacturing services, betting that Eco-driven growth and pipeline maturation will reverse the top-line contraction over time.
Executive Commentary
"We were very pleased to sign the Supply Assurance Agreement with Merck. We've been working on this for months, and it was a key reason why we had the confidence in our revenue projections for the year. More importantly, it was one of the final pieces of the jigsaw we needed to fall into place for us to be ready to commit to the transformation of Codexis into a full-service manufacturing innovator in the field of oligonucleotide manufacturing."
Dr. Stephen Dilley, Chief Executive Officer and Chairman
"We have streamlined our organization to focus on what we excel at, ecosynthesis, both manufacturing and providing production technologies to our customers. It's exciting to see Codexis evolve from an enzyme supplier to a production solutions partner. Our organization is now aligned to deliver services and products to all our customers."
Dr. Allison Moore, Chief Technical Officer (incoming CEO)
Strategic Positioning
1. Oligonucleotide Manufacturing Pivot
Codexis is executing a decisive pivot from enzyme supply to full-service oligonucleotide manufacturing, with the EcoSynthesis platform at the core. This transition is underpinned by growing commercial traction: 11 revenue-generating Eco contracts are now active, up from just one a year ago, and 40 more are in the pipeline. The company’s new facility, soon to be leased, will enable kilogram-scale GMP (Good Manufacturing Practice) production, targeting the surging demand for siRNA therapies—short interfering RNA, a rapidly emerging drug class.
2. Service Revenue Model and Commercial Realignment
The business model is shifting from legacy product sales to service-based revenue, with most new contracts structured as development services rather than product supply. This is a deliberate response to pricing pressure and diminishing returns in the traditional small molecule biocatalysis segment. Sales and marketing are now focused on expanding the Eco and ligase customer base, with legacy enzyme development efforts curtailed.
3. Cost Structure Overhaul and Organizational Streamlining
Codexis is implementing broad-based headcount reductions and restructuring R&D and commercial teams, aiming to reduce cash burn by 25 percent. This aligns the cost base with the new strategic focus and extends the company’s cash runway through 2027, supported by the Merck supply agreement’s non-dilutive funding.
4. Technical Leadership and Execution Focus
Leadership transition is central to the new phase: incoming CEO Dr. Allison Moore brings deep technical and operational expertise in scaling advanced manufacturing platforms, a critical asset as Codexis seeks to industrialize EcoSynthesis and deliver on large-scale, GMP-grade production.
5. Optionality and Modularity in Market Approach
Codexis is maintaining flexibility in how it serves customers: offering enzyme supply, technology licensing, and in-house siRNA manufacturing. The soon-to-be-leased facility is designed for modularity, supporting multiple business models (direct manufacturing, reagent supply, royalties), which hedges against market shifts and customer preferences.
Key Considerations
This quarter marks an inflection point as Codexis redeploys resources and realigns priorities to capture the oligonucleotide manufacturing opportunity. The company is betting on Eco platform scalability and commercial adoption to drive long-term growth, while managing near-term financial discipline.
Key Considerations:
- Commercial Traction in Eco Platform: The leap from one to 11 contracts in a year signals accelerating demand, but execution on scaling and delivery will be critical to sustain momentum.
- Legacy Business Decline: Reduced investment in small molecule biocatalysis may lead to further revenue softness, though pipeline drugs using Codexis enzymes in Phase III could provide upside with minimal incremental cost.
- Facility Buildout and GMP Readiness: Successful lease and operationalization of the new manufacturing site are prerequisites for capturing large-scale contracts and meeting regulatory standards.
- Cash Management and Burn Rate: The 25 percent burn reduction and Merck cash infusion are vital, but further capital needs may arise if Eco contracts ramp more slowly than anticipated.
Risks
Execution risk remains high as Codexis transitions from legacy enzyme sales to a service-driven oligonucleotide manufacturing model. Delays in facility buildout, customer adoption, or regulatory hurdles could impact revenue timing and margin realization. The shift away from small molecule biocatalysis exposes the company to concentration risk in the Eco platform and siRNA market volatility.
Forward Outlook
For the fourth quarter, Codexis expects to recognize a significant portion of the Merck contract revenue, with the remainder in Q1 2026. Management confirmed they will meet or slightly exceed the top end of 2025 guidance.
- Q4: Merck contract revenue recognition (majority in Q4, balance in Q1 2026)
- 2025: Top end of revenue guidance to be met or exceeded
For full-year 2026, guidance is pending and will be provided after year-end. Management highlighted:
- Ongoing shift from legacy product to Eco platform service revenue
- Cost base reduction and cash runway extension through 2027
Takeaways
Codexis is at a strategic crossroads, with its future increasingly tied to the success of EcoSynthesis in oligonucleotide manufacturing. The pivot is supported by new contracts, cost discipline, and a technical leadership refresh, but execution on scaling and commercial delivery will determine whether the company’s bet pays off.
- Eco Platform Execution: Investors should monitor customer adoption, facility ramp, and margin delivery as the Eco business scales.
- Legacy Pipeline Optionality: The outcome of Phase III trials using Codexis enzymes could provide non-dilutive upside, but is not the strategic focus.
- Cash and Capital Discipline: Burn rate reductions and Merck funding buy time, but rapid Eco revenue scaling is needed to sustain the model long-term.
Conclusion
Codexis is moving decisively into oligonucleotide manufacturing, leveraging Eco platform momentum and a streamlined cost base to target a high-growth market. The next 12 months will test the company’s ability to deliver on its new commercial and operational ambitions, as legacy revenue fades and execution risk rises.
Industry Read-Through
Codexis’s pivot underscores a broader trend toward vertical integration and service-based models in the CDMO (contract development and manufacturing organization) and bioprocessing sectors. Legacy enzyme supply is giving way to platform-driven manufacturing services, particularly in fast-growing modalities like siRNA. Competitors and partners in the oligonucleotide and genomic medicine supply chain should expect increased focus on GMP-scale capabilities, modular service offerings, and cost structure optimization. The margin and capital discipline themes echoed here are likely to reverberate across the advanced therapeutics manufacturing landscape.
