How big is it?
Marathon Petroleum bought back $7.3B of stock in the twelve months to Sep 30, 2026. At that pace, $5.0B covers about 8 months of buybacks.
The amount equals 24% of its free cash flow over the same twelve months ($20.8B).
Its diluted share count is down 7.9% from a year earlier.
An authorization is permission, not a promise: the company can buy less, more slowly, or not at all, and usually doesn't have to say when it buys.
