Marathon Petroleum Director Sells Nearly $1.3 Million in Company Stock
A director at Marathon Petroleum Corp. (MPC) has completed a significant stock sale valued at nearly $1.3 million, according to a recent regulatory filing. The transaction was executed under a pre-arranged trading plan, a key detail for investors monitoring insider activity.
FINDLAY, OH – Rucker Kim K.W., a member of the Board of Directors at Marathon Petroleum Corp., has sold a substantial portion of her holdings in the energy giant. A Form 4 filed with the U.S. Securities and Exchange Commission (SEC) on July 3, 2025, revealed the details of the transaction.
According to the filing, Director Rucker sold 7,392 shares of Marathon’s common stock at a price of 1,293,600.
Crucially, the sale was conducted under a Rule 10b5-1 trading plan. This type of plan allows company insiders to set up a predetermined schedule for buying or selling stocks at a future date. These plans are adopted when the individual is not in possession of material non-public information, providing an affirmative defense against potential accusations of insider trading. Rucker’s plan was reportedly adopted on May 19, 2024, over a year before the sale took place.
Insider sales are closely watched by the market for insights into executive sentiment. However, sales executed through 10b5-1 plans are generally viewed as less indicative of an insider’s current outlook on the company, as they are often part of long-term strategies for personal financial planning, diversification, or tax purposes.
Following the transaction, Rucker Kim K.W. continues to have a significant stake in the company, with a direct ownership of 18,944 shares of Marathon Petroleum Corp. stock. This ensures her financial interests remain aligned with those of other shareholders.
