Equity compensation and insider trading analyst

Routine option exercise-and-sell by Enliven’s CMO under a 10b5-1 plan.

Helen Louise Collins, Chief Medical Officer of Enliven Therapeutics, exercised options for 5,000 shares of Common Stock at $2.4800 per share and sold 5,000 shares at a weighted average price of $27.7600. This is a classic exercise-and-sell pattern converting an option position into cash.

The filing indicates these transactions were effected under a Rule 10b5-1 trading plan adopted on October 19, 2025. Such plans are pre-arranged and designed to standardize trading, which typically reduces the informational value of transaction timing as a signal of insider sentiment.

After the sale, Collins directly owns 25,000 Common Stock shares. The option exercised here was fully vested and exercisable, and the filing shows no remaining derivative securities from this option, suggesting completion of that particular grant’s lifecycle rather than a strategic shift in overall equity exposure.
