Key Financial Metrics

Material Changes vs. Prior Period

• Capital Raise: The company significantly strengthened its balance sheet through two follow-on public offerings in 2024 (January and May) and at-the-market (ATM) sales, raising aggregate net proceeds of approximately $806 million in the first nine months of 2024. This contrasts with $54 million raised in the same period in 2023.
• Expense Growth: Operating expenses increased by 70% year-over-year for the nine months ended September 30, 2024. R&D expenses rose primarily due to increased clinical trial activity for the ACHIEVE (DM1) and DELIVER (DMD) trials and higher manufacturing costs. G&A expenses increased due to higher headcount and significant stock-based compensation charges related to executive departures and modifications.
• Interest Income: Interest income surged to $19.3 million for the nine months ended September 30, 2024, compared to $5.9 million in the prior year, driven by higher cash balances and interest rates.

Guidance, Outlook, and Management Commentary

• Liquidity: Management believes existing cash, cash equivalents, and marketable securities ($723.7 million) are sufficient to fund operations and capital expenditures at least into the second half of 2026.
• Clinical Progress:
  • DYNE-101 (DM1): The ACHIEVE Phase 1/2 trial is fully enrolled through the 6.8 mg/kg cohort. Positive data reported in May 2024 showed robust muscle delivery and splicing correction. New data is expected in early January 2025.
  • DYNE-251 (DMD): The DELIVER Phase 1/2 trial reported positive data in September 2024, showing dose-dependent exon skipping and dystrophin expression exceeding levels of the current standard of care (eteplirsen) at lower doses. A registrational cohort of 32 participants has begun enrollment.
  • DYNE-302 (FSHD): Preclinical data announced in June 2024 demonstrated robust DUX4 suppression. The company is progressing through IND-enabling studies.
• Regulatory Status: The FDA cleared the IND for DYNE-101 in November 2024. The company is pursuing expedited approval pathways for its lead candidates.
• Risks: Key risks include the unproven nature of the FORCE platform, potential delays in clinical trials, reliance on third-party manufacturers, and the need for substantial additional funding to achieve profitability. The company will cease to qualify as an emerging growth company and smaller reporting company effective December 31, 2024, leading to increased compliance costs.

Investor Verification Checklist
