Key Financial Metrics

Material Changes vs. Prior Period

• Net Loss Increase: Net loss increased by $179.9 million (127.8%) primarily due to a $164.6 million increase in R&D expenses.
• R&D Expense Surge: R&D expenses rose 111.1% year-over-year. External costs increased by $152.6 million, driven by a $101.8 million increase in product manufacturing costs (supporting commercial launch preparations) and a $45.0 million increase in clinical trial expenses (initiation of Phase 3 studies).
• Capital Raise: In February 2026, the company completed an underwritten public offering of 12.65 million shares at $50.00 per share, generating $601.8 million in net proceeds. This significantly offset operating cash burn.
• Investment Portfolio: Total cash, cash equivalents, and investments increased to $2.74 billion as of March 31, 2026, compared to $2.44 billion at year-end 2025.

Guidance, Outlook, and Risks

Management Commentary and Outlook

• Clinical Milestones: The company completed enrollment for three pivotal Phase 3 trials for its lead candidate, VAX-31 (OPUS-1, OPUS-2, and OPUS-3). Topline data for OPUS-1 is expected in Q4 2026, with OPUS-2 and OPUS-3 data expected in H1 2027.
• Manufacturing: Construction of a dedicated commercial manufacturing suite with Lonza in Switzerland is complete. A custom fill-finish line in North Carolina is under construction.
• Liquidity: Management believes current cash and investments are sufficient to fund operations for at least 12 months from the filing date.
• Program Updates: The company plans to initiate a Phase 1 adult study for VAX-A1 (Group A Strep) in mid-2026. The VAX-GI program remains paused beyond preclinical development.

Risks and Contingencies

• Regulatory Approval: No products are approved; success depends on FDA/EMA approval of VAX-31 and VAX-24. The FDA may challenge the company's Chemistry, Manufacturing, and Controls (CMC) strategy.
• Capital Needs: The company expects to incur substantial losses for the foreseeable future and will require additional funding to complete development and commercialization.
• Third-Party Reliance: The company relies entirely on third-party manufacturers (Lonza, Thermo Fisher) and suppliers. Delays or quality issues at these facilities could materially harm the business.
• Competition: Major competitors (Pfizer, Merck, Sanofi) have greater resources and are advancing their own pneumococcal conjugate vaccine (PCV) candidates.

Investor Verification Checklist

• Phase 3 Enrollment: Verify the completion of enrollment in the OPUS-1, OPUS-2, and OPUS-3 trials and the timeline for topline data release.
• Manufacturing Readiness: Confirm the status of the Lonza facility certification and the North Carolina fill-finish line build-out.
• Cash Burn Rate: Monitor the quarterly cash burn rate against the $2.74 billion cash balance to assess runway beyond the 12-month guidance.
• Regulatory Interactions: Track any FDA feedback regarding the CMC strategy or non-inferiority standards for the VAX-31 program.
• Capital Markets: Watch for additional equity raises or debt financings given the company's lack of revenue and high R&D spend.
