Material Changes and Clinical Updates

- FSHD Program (DYNE-301): The Company is deferring the Investigational New Drug (IND) application submission for its facioscapulohumeral muscular dystrophy program, originally targeted for the second half of 2022. An update is planned for 2023.
Guidance, Outlook, and Risks
Outlook: Management is prioritizing resources on the DYNE-101 and DYNE-251 clinical programs. The deferral of the FSHD IND submission is intended to extend the cash runway through 2024.
Risks and Contingencies: The filing includes standard forward-looking statement disclaimers. Key risks include:
- Uncertainties in clinical trial initiation, enrollment, and results.
- Potential insufficiency of cash resources to fund operations sooner than expected.

Investor Verification Checklist
- Verify the actual cash balance and burn rate in the most recent Form 10-Q to confirm the "through 2024" runway estimate.
- Monitor patient enrollment rates for the DELIVER and ACHIEVE trials to ensure the second-half 2023 data readout timeline remains feasible.
- Review the specific reasons for the FSHD program deferral and the criteria for the 2023 program update.
- Track regulatory communications regarding the starting doses and cohort designs for both lead candidates.
