Overall, slightly positive due to RSU vesting and ESPP purchase, balanced by the routine tax sale.

• Inclusion of 15 shares purchased under the Employee Stock Purchase Plan (ESPP) on November 19, 2025, demonstrates continued insider investment in the company.

Key Dates

Recommendation

This Form 4 filing details a routine insider transaction where the CFO disposed of shares to cover tax obligations from RSU vesting and also purchased shares through an ESPP. These are standard compensation and investment activities for executives and do not provide new material information that would significantly alter the investment thesis for Penumbra Inc. Therefore, a 'hold' recommendation is appropriate as there's no strong signal for a buy or sell based solely on this filing.
