Material Changes vs. Prior Period

• Net Loss Increase: Net loss increased by $3.9 million (44%) year-over-year, primarily driven by a $2.8 million foreign currency transaction loss and a $1.4 million increase in General and Administrative (G&A) expenses.
• Foreign Currency Impact: The company recorded a $2.8 million foreign currency transaction loss in Q1 2025, compared to a $0.6 million gain in Q1 2024, due to the weakening of the U.S. dollar against the pound sterling.
• Debt Conversion: In February 2025, the company converted the outstanding principal and accrued interest of its Novartis Loan Note ($5.7 million carrying value) into 17.1 million ordinary shares. Additionally, Novartis exercised warrants for 1.4 million shares.
• R&D Spend Shift: Total R&D expenses remained relatively flat ($3.9 million), but the composition shifted. Spending on setrusumab increased by $1.3 million (driven by manufacturing agreements with Ultragenyx), while spending on alvelestat decreased by $1.2 million.
• Liquidity: Cash balances decreased by $7.3 million during the quarter, though the company maintains a cash runway extending into 2027.

Outlook, Risks, and Management Commentary

• Liquidity Outlook: Management expects current cash resources ($62.5 million) to fund operations and capital expenditures into 2027. However, additional external funding will be required to complete development plans and commercialize products.
• Development Progress: Setrusumab has received Orphan Drug, PRIME, and Breakthrough Therapy designations. Alvelestat has received Orphan Drug and Fast Track designations. The company is preparing for Phase 3 studies for alvelestat.
• Key Risks:
  • Capital Requirements: The company has an accumulated deficit of $472 million and expects to continue incurring losses. Failure to secure additional funding could force delays or termination of programs.
  • Currency Volatility: As a U.K. company reporting in U.S. dollars, fluctuations in exchange rates significantly impact reported net loss and cash flow.
  • Regulatory and Clinical Risk: Success depends on clinical trial outcomes and regulatory approvals, which are uncertain.
• Contingencies: The company has potential future milestone and royalty obligations to AstraZeneca (up to $114.3 million) and Novartis based on sales and development milestones, though the fair value of equity milestones was deemed negligible as of March 31, 2025.

Investor Verification Checklist

• Cash Runway: Verify the specific monthly burn rate and the assumptions used to project the runway into 2027.
• Setrusumab Collaboration: Review the terms of the manufacturing and supply agreement with Ultragenyx to understand future cash outflows.
• Currency Hedging: Assess if the company has hedging strategies to mitigate the significant foreign currency transaction losses observed in Q1 2025.
• Dilution: Monitor the impact of the recent conversion of the Novartis Loan Note and warrant exercises on shareholder ownership.
• Alvelestat Phase 3: Confirm the timeline and funding requirements for the upcoming Phase 3 study for alvelestat.
