Management Comments

• The Board of Directors determined that it is in the best interest of the Company and its stockholders to terminate the HyBryte development program.

Industry Context

StockSavvy.ai notes that the termination of a late-stage clinical program due to futility is a significant setback for small-cap biotech firms, often leading to a pivot toward M&A or a focus on earlier-stage assets to preserve cash.

Comparison to Industry Standards

• The failure of a Phase 3 trial for futility is a common but severe risk in the biotechnology sector, similar to recent failures seen in other small-cap oncology developers.
• The receipt of a Nasdaq deficiency notice is a standard regulatory hurdle for small-cap companies facing clinical trial setbacks.

Management Changes

Stakeholder Impact

• Shareholders face increased volatility and potential delisting risk.
• Employees involved in the HyBryte program may be impacted by the wind-down.
• Creditors may be concerned by the loss of the primary clinical asset.

Next Steps

• Monitor the closing bid price of common stock to regain Nasdaq compliance by December 7, 2026.
• Complete the orderly wind-down of the FLASH2 clinical trial.
• Evaluate strategic options including potential merger and acquisition opportunities.
• Continue development of the dusquetide (SGX945) pipeline.

Key Dates

Recommendation

The loss of the lead clinical asset combined with Nasdaq delisting pressure creates significant uncertainty and downside risk, making the stock unattractive until a clear strategic path or M&A outcome is established.
