Key Financial Metrics

Note: All figures in millions unless otherwise noted. Cash and investments as of September 30, 2025, include $281.1 million in cash and cash equivalents and $2.39 billion in investments.

Material Changes vs. Prior Period

• Increased Operating Expenses: Total operating expenses rose 73.2% quarter-over-quarter (Q3 2025 vs. Q3 2024) and 59.4% year-to-date. This increase was driven primarily by Research and Development (R&D) expenses, which grew 79.5% in Q3 and 61.0% YTD.
• R&D Drivers: The surge in R&D costs was largely due to increased external costs for product manufacturing ($69.4 million increase in Q3) and clinical activities to support the adult and infant PCV programs and prepare for potential commercial launches. Internal personnel costs also increased due to headcount growth.
• Net Loss Expansion: Net loss increased 106.4% in Q3 and 59.1% YTD compared to the prior year periods, reflecting the accelerated spending on development and manufacturing scale-up.
• Other Income: Total other income decreased 19.7% in Q3 primarily due to a reduction in foreign currency gains, though it increased 60.5% YTD due to higher interest income and foreign currency gains.

Guidance, Outlook, and Management Commentary

• PCV Franchise Progress:
  • VAX-31 (Adult): Following positive Phase 1/2 results and FDA Breakthrough Therapy Designation (BTD) expansion to include pneumonia prevention, the company selected the High dose for Phase 3. The pivotal non-inferiority study is planned to initiate in December 2025, with topline data expected in 2026.
  • VAX-24 (Pediatric): Final Phase 2 data announced in November 2025 confirmed robust immunogenicity and safety, consistent with interim data. The company plans to initiate a Phase 3 program with an optimized dose of VAX-24 or VAX-31 pending further infant study readouts.
  • VAX-31 (Pediatric): The Phase 2 dose-finding study advanced to its third stage in September 2025 with an optimized dose arm. Topline data is expected by the end of the first half of 2027.
• Program Pauses: In August 2025, the company paused advancement beyond preclinical development for VAX-A1 (Group A Strep) and VAX-GI (Shigella) to prioritize resources for the PCV franchise.
• Manufacturing Strategy: In September 2025, Vaxcyte entered a master services agreement with Thermo Fisher Scientific for commercial fill-finish capacity in North Carolina, representing a long-term commitment of up to $1 billion. The company continues to build out a dedicated suite with Lonza in Switzerland.
• Liquidity: Management believes existing cash, cash equivalents, and investments ($2.67 billion) are sufficient to fund operations and capital expenditures for at least 12 months from the filing date. No specific financial guidance was provided for future periods.
• Risks: Key risks include the failure of clinical trials, manufacturing delays, regulatory hurdles, and the need for substantial additional capital to achieve profitability. The company has no source of product revenue and expects to incur losses for the foreseeable future.

Investor Verification Checklist

• Cash Burn Rate: Verify the sustainability of the current cash position ($2.67 billion) against the accelerating R&D burn rate (approx. $213 million net loss in Q3 alone).
• Manufacturing Milestones: Monitor the timeline for the Lonza facility build-out in Switzerland and the Thermo Fisher agreement execution to ensure commercial supply readiness aligns with Phase 3 timelines.
• Phase 3 Initiation: Confirm the December 2025 start date for the VAX-31 adult Phase 3 study and the criteria for selecting the pediatric Phase 3 candidate (VAX-24 vs. VAX-31).
• Capital Requirements: Assess the likelihood of future dilution or debt financing given the $1 billion manufacturing commitment and the multi-year timeline to commercialization.
• Competitive Landscape: Evaluate the impact of competitor PCV candidates (e.g., Pfizer's PCV25, Merck's PCV21) on Vaxcyte's market opportunity and potential pricing power.
