Dyne Therapeutics, Inc. (DYN)·Q2 2025 Earnings Summary

Executive Summary

• Q2 2025 reflected continued clinical/regulatory progress and a strengthened balance sheet: cash, cash equivalents and marketable securities were $683.9M as of June 30, 2025, and management extended expected runway into Q3 2027 following a $230.0M equity offering and $275M debt facility .
• DYNE-101 (DM1) received FDA Breakthrough Therapy Designation and the ACHIEVE registrational expansion cohort protocol was revised to use video hand opening time (vHOT) as the primary endpoint; enrollment targeted for completion in Q4 2025 with potential U.S. Accelerated Approval submission in late 2026 .
• DYNE-251 (DMD) registrational expansion cohort (32 patients) was fully enrolled; data expected late 2025 and a potential U.S. Accelerated Approval submission remains planned for early 2026 .
• EPS was -$0.97 vs Wall Street consensus of -$0.933; a modest miss likely tied to higher R&D as programs advance into registrational cohorts. Revenue was not reported (pre-revenue profile) and consensus was $0.00; estimates from S&P Global* .
• Near-term stock catalysts include late-2025 DELIVER (DYNE-251) and mid-2026 ACHIEVE (DYNE-101) data, and subsequent accelerated approval filings; extended runway reduces financing overhang and supports execution through potential first U.S. launch in 2027 .
