Material Changes vs. Prior Period

• Net Loss Increase: Net loss increased by $80.5 million (48.6%) primarily due to higher operating expenses.
• R&D Expense Surge: R&D expenses rose by $62.7 million (51.4%). This was driven by:
  • Apitegromab: A $37.6 million increase due to Phase 3 SAPPHIRE trial costs, the ONYX extension study, and the Phase 2 EMBRAZE obesity trial (including GLP-1 RA drug purchases).
  • SRK-439: An $11.0 million increase in preclinical and manufacturing development costs.
  • SRK-181: A $4.2 million decrease due to reduced pembrolizumab purchases compared to 2023.
• G&A Expense Increase: G&A expenses rose by $18.1 million (36.7%) due to increased headcount, employee compensation, and professional service fees to support commercialization infrastructure.
• Cash Position: Total cash and marketable securities increased by $157.3 million, primarily from a $324.4 million equity offering in October 2024 and warrant exercises, partially offset by operating cash outflows.

Guidance, Outlook, and Management Commentary

• Apitegromab (SMA):
  • Completed Phase 3 SAPPHIRE trial in October 2024 with positive top-line results achieving the primary endpoint.
  • Submitted U.S. Biologics License Application (BLA) to the FDA in January 2025 with a request for Priority Review.
  • Plans to submit a marketing authorization application to the EMA in Q1 2025.
  • Targeting a U.S. commercial launch in Q4 2025 if approved.
• Cardiometabolic Expansion:
  • Initiated Phase 2 EMBRAZE trial (apitegromab + GLP-1 RA) in May 2024; enrollment completed in September 2024. Top-line results expected Q2 2025.
  • Advancing SRK-439 (preclinical myostatin inhibitor) toward an IND submission in Q3 2025.
• SRK-181 (Oncology):
  • Phase 1 DRAGON trial enrollment completed in December 2023. Data presented at ASCO (June 2024) and SITC (Nov 2024) showed encouraging responses in anti-PD-(L)1 resistant patients.
• Liquidity Outlook: Management believes existing cash and marketable securities ($437.3 million) are sufficient to fund operations into Q4 2026. However, additional capital will be required to complete clinical development and commercialization.
• Risks: Key risks include the uncertainty of regulatory approval for apitegromab, the ability to build a commercial organization, reliance on third-party manufacturers, and the need for future financing.

Investor Verification Checklist

• Regulatory Status: Verify the FDA's acceptance of the apitegromab BLA and the timeline for the Priority Review decision.
• Commercial Readiness: Assess the progress of hiring and infrastructure build-out for the anticipated Q4 2025 launch.
• Cash Burn Rate: Monitor quarterly cash burn to confirm the runway extends to Q4 2026 as projected.
• Clinical Data: Review the full data readout from the Phase 2 EMBRAZE trial (expected Q2 2025) to validate the obesity indication strategy.
• Debt Covenants: Review the terms of the Amended and Restated Loan and Security Agreement (Feb 2025) for any restrictive covenants or milestone triggers.
