[144] MARATHON PETROLEUM CORPORATION SEC Filing

Rhea-AI Filing Summary

Marathon Petroleum Corporation (MPC) has filed a Form 144 indicating a proposed sale of 7,392 common shares through Fidelity Brokerage Services on 3 July 2025 at the NYSE. Based on the quoted aggregate market value of $1.29 million, the implied price per share is approximately $175. The shares represent roughly 0.0024 % of the 307.2 million shares outstanding disclosed in the form. The shares were originally acquired via restricted-stock vesting on 1 April 2019 and are being sold for the account of an unidentified insider. No other sales were reported in the past three months, and no additional remarks, 10b5-1 plan information, or adverse disclosures accompany the notice.

Insights

Securities Analyst

TL;DR: Small Form 144 filing; insider plans to sell 7,392 MPC shares (≈$1.3 m); immaterial to float, neutral signal.

The filing details are straightforward: an insider intends to liquidate a modest stake representing just 0.002 % of shares outstanding. The sale value is insignificant relative to MPC’s multi-billion-dollar market capitalisation, and no pattern of consecutive insider disposals is indicated ("Nothing to Report" for prior three months). Absence of 10b5-1 plan data means timing discretion is unclear, yet there is also an affirmative representation that no undisclosed negative information exists. Overall, the transaction appears routine and lacks material market impact.
