Insights

Insider transactions analyst

Routine Form 4 sales; modest size at sub-$1 prices.

The CFO of KALA BIO disclosed two open-market sales: 32,230 shares at a weighted average of $0.83 on 10/22/2025 and 967 shares at $0.82 on 10/23/2025. The price range for the larger sale was $0.82–$0.84, and the filing notes availability of detailed breakdowns upon request.

Post-transaction beneficial ownership was 29,873 then 28,906 shares (direct), with a footnote indicating the 28,906 includes unvested RSUs. This reads as an administrative disclosure of insider activity.

Given the limited size and standard nature of these trades, the likely market impact is minimal. Actual effects, if any, depend on trading liquidity and investor interpretation of insider activity.
