Summary

Marathon Petroleum held its 2026 Annual Meeting on April 29, 2026, where shareholders elected four Class III directors, ratified PricewaterhouseCoopers LLP as independent auditor, approved named executive officer compensation on an advisory basis, and rejected two corporate governance proposals requiring 80% supermajority approval.

Key takeaways

Four Class III directors—Maryann T. Mannen, Eileen P. Paterson, J. Michael Stice, and John P. Surma—were elected to serve until the 2029 annual meeting; all received between 196M–202M votes for amid 49.3M broker non-votes.

PricewaterhouseCoopers LLP was ratified as independent auditor with 254.4M votes for and no broker non-votes, indicating strong audit continuity.

Advisory say-on-pay proposal passed with 202.1M votes for, though 49.3M broker non-votes limited total support to ~77% of outstanding shares entitled to vote.

Proposal to declassify the Board failed to reach the required 80% threshold (206.1M for, or ~70% of outstanding shares), preserving current classified board structure.

Proposal to eliminate supermajority provisions also failed to meet the 80% requirement (205.8M for, or ~70% of outstanding shares), maintaining existing voting thresholds for charter amendments.

Full analysis

The 2026 Annual Meeting results reflect broad shareholder support for director elections and auditor ratification, but highlight meaningful resistance to structural governance reforms. While all four Class III director nominees were elected, each faced over 10 million votes against and identical broker non-votes (49.3M), suggesting institutional passivity or delegation on director slate matters. The auditor ratification passed decisively with no broker non-votes, reinforcing confidence in financial oversight. Say-on-pay passed comfortably in absolute terms but garnered only ~77% support among outstanding shares due to the full block of broker non-votes—consistent with typical retail-heavy voting patterns in energy companies. Critically, both the board declassification and supermajority elimination proposals fell short of the 80% threshold, receiving ~70% support each. This outcome preserves Marathon Petroleum’s current classified board (with staggered three-year terms) and supermajority requirements for charter amendments, limiting near-term governance flexibility. These rejections signal that a substantial portion of the voting base—particularly holders who instructed brokers not to vote or abstained—remains cautious about accelerating governance changes, possibly reflecting satisfaction with current board composition or strategic direction.
