Industry Context

This is a routine corporate governance update reflecting a standard executive transition within a master limited partnership (MLP) structure. The appointment of an executive from the parent company (Marathon Petroleum Corporation) to the general partner's board is a common practice, aligning governance with the parent entity's strategic direction. Such changes are typical and generally do not indicate broader industry shifts unless accompanied by significant strategic announcements.

Comparison to Industry Standards

• The practice of appointing an executive from the parent company to the general partner's board as a non-compensated management director is a common governance model within the MLP sector. This structure is observed in many midstream MLPs, such as Enterprise Products Partners L.P. or Energy Transfer LP, where parent company executives often hold positions on the general partner's board to ensure strategic alignment and oversight.
