Noncontrolling Interest [Abstract] |
Master Limited Partnership | Master Limited Partnership We own the general partner and a majority limited partner interest in MPLX, which owns and operates crude oil and light product transportation and logistics infrastructure as well as gathering, processing and fractionation assets. We control MPLX through our ownership of the general partner interest and, as of March 31, 2026, we owned approximately 64 percent of the outstanding MPLX common units. Unit Repurchase Program On August 5, 2025, MPLX announced its board of directors approved a $1.0 billion unit repurchase authorization in addition to the $1.0 billion unit repurchase authorization announced on August 2, 2022. These u nit repurchase authorizations have no expiration date. MPLX may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, accelerated unit repurchases, tender offers or open market solicitations for units, some of which may be effected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be suspended, discontinued or restarted at any time. Total unit repurchases were as follows for the respective periods:
| Three Months Ended March 31, |  |
(In millions, except per unit data) | 2026 |  | 2025 |  |  |  |
Number of common units repurchased | 1 |  |  | 2 |  |  |  |  |

Average cost per unit | $ | 56.63 |  |  | $ | 52.48 |  |  |  |  |
As of March 31, 2026, MPLX had approximately $1.07 billion remaining under its unit repurchase authorizations. Agreements We have various long-term, fee-based commercial agreements with MPLX. Under these agreements, MPLX provides transportation, storage, distribution and marketing services to us. With certain exceptions, these agreements generally contain minimum volume commitments. These transactions are eliminated in consolidation but are reflected as intersegment transactions among our Refining & Marketing, Renewable Diesel and Midstream segments. We also have agreements with MPLX that establish fees for operational and management services provided between us and MPLX and for executive management services and certain general and administrative services provided by us to MPLX. These transactions are eliminated in consolidation but are reflected as intersegment transactions between corporate and our Midstream segment. Noncontrolling Interest As a result of equity transactions of MPLX, we are required to adjust non-controlling interest and additional paid-in capital. Changes in MPC’s additional paid-in capital resulting from changes in its ownership interests in MPLX were as follows:
