Securities Analyst

TL;DR: Transactions are routine insider sales under a preset plan and do not by themselves indicate a material change in ownership.

The Form 4 records sales of 5,000 shares at a weighted average of $19.0946 and 1,000 shares at $20.25, leaving reported beneficial holdings of 921,892 shares after the second sale. The use of a Rule 10b5-1 plan and the trustee-held record ownership reduce ambiguity about timing and intent, but the filing does not provide any new operational or financial information about Enliven Therapeutics that would affect valuation.
