Penumbra (PEN) – CEO Adam Elsesser Form 4 filing (23 Jul 2025):
The CEO exercised 27,976 stock options at a $30 strike that were set to expire on 16 Sep 2025, immediately selling 16,150 shares under a pre-arranged Rule 10b5-1 plan at weighted-average prices of $232-$234. After the transactions, his direct ownership increased to 146,258 common shares, while he still holds 577,582 shares through the Siegel/Elsesser Revocable Trust and 83,932 fully vested options.
Proceeds from the sale likely funded the exercise price and tax obligations. The filing does not signal operational changes and leaves the CEO with a substantial equity position, but the market may view the discretionary share sales as a mildly negative sentiment indicator.
