COHEN JONATHAN Z 4

What Happened
Jonathan Z. Cohen, a director of Marathon Petroleum Corp. (MPC), was granted 727.742 shares on 2026-04-30 as an equity award. The Form 4 lists the acquisition price as $0.00 (this reflects a compensation award rather than an open-market purchase). Footnotes state the grant represents his annual 2026 equity retainer and that 313.518 of the shares were acquired via dividend reinvestment and had not been previously reported.

Context
This was a compensation-related award (routine retainer) rather than a buy or sale in the open market. Awards and dividend reinvestment entries are common for directors and don’t necessarily signal a personal buy or sell decision. Retail investors monitoring insider activity should note the nature of the transaction (compensation + dividend reinvestment) and check other filings or company disclosures for fuller ownership context.
