Key Financial Metrics

Material Changes vs. Prior Period

• Increased Operating Expenses: Total operating expenses rose by $24.9 million (65%) year-over-year, driven primarily by increased R&D spending.
• R&D Expense Growth: R&D expenses increased by $17.7 million. This was largely due to the advancement of the APG777 program (Phase 2 clinical trials), increased personnel costs, and higher equity-based compensation.
• G&A Expense Growth: G&A expenses increased by $7.2 million, attributed to higher personnel-related costs and equity-based compensation as the company expands its operations.
• Net Loss Expansion: Net loss increased by $23.2 million to $55.3 million, reflecting the higher burn rate despite a $1.8 million increase in interest income.
• Cash Position: Cash and cash equivalents decreased by approximately $379 million from the prior year period, reflecting the company's cash burn and lack of significant financing activities in Q1 2025 compared to the $450 million raised in Q1 2024.

Guidance, Outlook, and Risks

Outlook and Liquidity: Management estimates that existing cash, cash equivalents, and marketable securities ($681.4 million total as of March 31, 2025) are sufficient to fund operating expenses and capital requirements into the first quarter of 2028. The company expects to continue incurring significant losses as it advances clinical trials.

Key Clinical Updates:

• APG777 (Anti-IL13): Phase 2 Part A dosing completed in February 2025; Part B dosing commenced. Topline data from Part A expected mid-2025.
• APG990 (Anti-OX40L): Positive interim safety and PK data announced in March 2025. Planning Phase 1b trial of combination therapy (APG279) in 2025.
• APG808 (Anti-IL4Rα): Positive interim results from Phase 1b asthma trial announced in May 2025 (post-period).

Risks and Contingencies:

• Capital Requirements: The company requires substantial additional funding to complete development and commercialization. Failure to raise capital could force delays or discontinuation of programs.
• Regulatory and Clinical Risk: No products are approved; success depends on clinical trial outcomes and regulatory approvals, which are uncertain.
• Third-Party Reliance: Reliance on third parties (e.g., Paragon, WuXi Biologics, Samsung Biologics) for discovery, manufacturing, and clinical trials introduces supply chain and execution risks.
• Macroeconomic Factors: Risks include inflation, interest rate volatility, and potential trade tariffs affecting manufacturing costs.

Investor Verification Checklist

• Cash Runway: Verify the accuracy of the management estimate that current liquidity supports operations through Q1 2028, given the high quarterly burn rate (~$48M operating cash outflow).
• APG777 Clinical Data: Monitor the release of 16-week topline data from the Phase 2 Part A trial expected in mid-2025, which is critical for the lead asset's valuation.
• Manufacturing Agreements: Review the terms of the new Master Services Agreement with Samsung Biologics (effective Feb 2025) regarding minimum purchase commitments and potential exit fees.
• Equity Dilution: Assess the remaining capacity under the At-The-Market (ATM) facility ($255.1 million available) and the potential for future equity raises to fund operations.
• Related Party Transactions: Review ongoing payments and milestone obligations to Paragon Therapeutics, a related party and significant shareholder.
