Insights

TL;DR: The filing documents a tax-withholding share forfeiture of 2,217 ENTA shares; this is a routine, non-sale insider action with limited market impact.

The transaction reported is explicitly described as forfeiture to cover withholding taxes tied to settlement of an RSU award granted August 8, 2022. The form shows a transaction date of 08/08/2025 and a per-share figure of $6.99. Importantly, the reporting person retains direct beneficial ownership of 22,590 shares after the forfeiture. From a trading-impact perspective, the entry documents internal tax withholding rather than an open-market sale, so it is unlikely to materially affect ENTA's share supply or signal a change in insider sentiment on its own.

TL;DR: This Form 4 records an internal withholding of shares upon RSU settlement and does not report any change in officer status or an open-market sale.

The filing identifies Scott T. Rottinghaus as the reporting person and lists his relationship to the issuer as Chief Medical Officer. The explanatory note states the 2,217 shares were forfeited solely to cover withholding taxes from settlement of RSUs granted on August 8, 2022. The signature block shows the filing was executed by an attorney-in-fact. There is no indication in the document of a change in employment status, additional grants, or market sales by the reporting person; the disclosed action is administrative in nature.
