Rhea-AI Filing Summary

Fairmount Funds Management LLC and related parties report a 6.3% stake in Enliven Therapeutics, Inc. This Amendment No. 4 updates prior Schedule 13G filings and shows 3,711,444 shares of the issuer's common stock are reported as beneficially owned on a shared basis by Fairmount Funds Management LLC, Fairmount Healthcare Fund II L.P., and two managing members, Peter Harwin and Tomas Kiselak. The percentage is calculated using 58,959,717 shares outstanding as of June 16, 2025.

Signatures and a joint filing agreement dated August 14, 2025, accompany the amendment.

Insights

Financial Analyst

TL;DR: A disclosed 6.3% stake by an investment adviser and its fund signals a material passive holding requiring monitoring but not an immediate control change.

Fairmount and affiliated parties report shared beneficial ownership of 3,711,444 shares (6.3% of outstanding stock as of June 16, 2025). The filing is an amendment to prior Schedule 13G statements and documents that voting and dispositive authority over Fund II's shares are delegated to Fairmount. For investors, a >5% passive disclosure is material because it can influence liquidity and may presage further activity, but the filing explicitly disclaims an intent to change control. The calculation basis (58,959,717 shares) is provided, enabling straightforward verification of the reported percentage.

Corporate Governance Expert

TL;DR: The amendment clarifies ownership structure and delegation of voting/dispositive power, important for governance transparency.

The statement confirms that Fund II directly holds the shares while delegating sole voting and dispositive powers to Fairmount, and that managing members Harwin and Kiselak may be deemed beneficial owners for Section 13(d) purposes. The filing includes a joint filing agreement and signatures, strengthening disclosure completeness. The explicit disclaimer by Fund II regarding revocability of delegation (61 days) and the limited-purpose disclaimers by Fairmount and the individuals are governance-relevant details investors and the board should note.
