Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased to $1.45 million from $0.59 million, driven by collaboration revenue recognized from the Bristol-Myers Squibb (BMS) agreement.
• Expense Increases: Operating expenses rose by $4.9 million. Research and Development (R&D) expenses increased by $2.8 million, primarily due to a $3.6 million increase in facility-related costs associated with the expansion and build-out of laboratory space at 60 First Street and 500 Arsenal Street. General and Administrative (G&A) expenses increased by $2.1 million, driven by a $1.3 million rise in personnel expenses.
• Investment Portfolio: The company significantly increased its short-term investments, purchasing $48.3 million in securities during the quarter, compared to $107.2 million in the prior year. This resulted in a net cash outflow of $47.7 million in investing activities.
• Lease Liabilities: Significant non-cash lease activity occurred in Q1 2025, with the commencement of additional lease components at 60 First Street and 500 Arsenal Street, increasing operating lease right-of-use assets by approximately $83.8 million.

Outlook, Risks, and Management Commentary

• Going Concern Warning: Management has determined that substantial doubt exists regarding the company's ability to continue as a going concern for 12 months from the filing date. The company expects to incur operating losses for the foreseeable future and will require additional financing to meet obligations.
• Cash Runway: Management believes existing cash, cash equivalents, and investments ($144.3 million) are sufficient to fund operations into the first half of 2026. However, this estimate is based on assumptions that may prove incorrect.
• Pipeline Progress: In March 2025, the company announced a preclinical program for alpha-1 antitrypsin deficiency. The company expects to advance its Wilson's Disease program and the new alpha-1 antitrypsin program into the clinic next year. Chronic granulomatous disease remains the most advanced blood program.
• Legal Proceedings: The company is appealing a March 2025 court decision that dismissed its claims against its landlord (NW Cambridge Property Owner, LLC) regarding disputed rental credits totaling $13.9 million. The company continues to make disputed payments under protest.
• Regulatory Risks: The filing highlights risks related to potential FDA staffing reductions, government shutdowns, and funding shortages that could delay regulatory reviews. It also notes the impact of new U.S. tariffs imposed in April 2025.

Investor Verification Checklist

• Capital Raise Strategy: Verify the status of the "at the market" offering program and any plans for new equity or debt financing to address the going concern warning.
• Lease Dispute Resolution: Monitor the outcome of the appeal regarding the $13.9 million in disputed lease payments with NW Cambridge Property Owner, LLC.
• Cash Burn Rate: Track quarterly operating cash burn against the stated runway into the first half of 2026 to assess the urgency of future capital needs.
• Clinical Milestones: Confirm timelines for advancing the Wilson's Disease and alpha-1 antitrypsin deficiency programs into clinical trials as projected for 2026.
• Regulatory Environment: Assess the potential impact of FDA staffing changes and government funding levels on the company's IND submission timelines.
