Insights

TL;DR: Routine tax withholding; immaterial for valuation.

Code F indicates the shares were surrendered to satisfy tax obligations rather than sold on the open market, so the 908-share reduction (�0.9% of Mannen's holdings) has negligible signalling value. The CEO retains a sizable stake of 100,547 shares, maintaining alignment with shareholders. Overall, the filing is non-impactful for MPC’s investment thesis.
