Industry Context

This announcement reflects a strategic shift in the COVID-19 vaccine market, where established pharmaceutical giants like Sanofi are acquiring or licensing successful vaccine candidates from smaller biotech firms like Novavax. This allows Novavax to monetize its developed assets and focus on its core technology platform and pipeline, while Sanofi leverages its global commercial and regulatory infrastructure to maximize the reach of Nuvaxovid. It also highlights the ongoing demand for diverse vaccine technologies, including protein-based, non-mRNA options.

Comparison to Industry Standards

• The transfer of marketing authorization to a larger pharmaceutical company like Sanofi is a common strategy for biotech firms to maximize the commercial potential of their products, similar to licensing agreements seen with companies like BioNTech (partnering with Pfizer for Comirnaty) or Moderna (retaining commercial rights but leveraging global distribution networks).
• The $225 million in non-dilutive capital secured year-to-date 2025 is a significant inflow for a biotech company, comparable to upfront payments or early-stage milestones in major pharmaceutical collaborations, providing financial stability without issuing new equity.
• The continued eligibility for future milestones and royalties aligns with standard industry licensing models, where the innovator company benefits from the long-term success of the product.

Stakeholder Impact

• Shareholders: Benefit from the $25 million milestone payment and $225 million in non-dilutive capital, which strengthens the company's financial position without diluting existing shares. Potential for future royalties and milestones provides long-term value.
• Employees: Strategic focus shift may impact resource allocation, but the overall partnership strengthens the company's outlook.
• Customers (Vaccine Recipients): Sanofi's global commercial reach may improve access to Nuvaxovid.
• Partners (Sanofi): Gains full commercial and regulatory control over Nuvaxovid in the U.S., expanding its vaccine portfolio.

Next Steps

• Anticipated receipt of the $25 million milestone payment in the first quarter of 2026.
• Sanofi to take full responsibility for commercial and regulatory activities for Nuvaxovid in the U.S.
• Potential for additional future milestones and royalties from Sanofi under the Collaboration and License Agreement.
• Sanofi's global marketing of Nuvaxovid and potential development of combination products or new vaccines utilizing Novavax's Matrix-M adjuvant.
