Why is the transaction price per share listed as 0.0000 in this Marathon Petroleum (MPC) Form 4?

The price per share appears as 0.0000 because the shares were granted as an equity retainer award, not bought in the market. For compensation awards, Form 4 often shows a zero price since the director receives shares as part of their service-related compensation package.

"Represents the reporting person's annual 2026 equity retainer award."

dividend reinvestment financial

"Includes 1,216.56 shares acquired pursuant to dividend reinvestment and not previously reported"

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.

Rule 16a-11 regulatory

"not previously reported pursuant to Rule 16a-11."

Common Stock financial

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
