CEO Mark Lashier received total compensation of approximately $23.1 million, which is within a reasonable range for the chief executive of a large-cap integrated energy company with a market cap of $70.6 billion. The pay structure is well-designed from a performance perspective: approximately 91% of the CEO's target pay is at risk, with 68% explicitly performance-based through the annual cash bonus program (tied to safety, operational, and financial metrics) and a long-term performance share program (tied to three-year return on capital employed and relative total shareholder return against peers). The 2023–2025 performance share program paid out at 160% of target, reflecting genuine outperformance — PSX ranked 6th out of 14 peers in total shareholder return and delivered a return on capital employed above the maximum threshold — and the pay-for-performance alignment is further supported by PSX's strong 3-year price return of +95.5%, which substantially outperforms the peer group median of +40.6%.

Ernst & Young has served as PSX's auditor since 2011, giving it approximately 14 years of tenure — well below the 25-year threshold that would trigger a concern. Non-audit fees (audit-related fees of $2.1M plus tax fees of $0.2M plus all other fees of $0.3M = $2.6M) represent about 20% of core audit fees ($12.8M), which is comfortably below the 50% threshold that would raise independence concerns. EY is a Big 4 firm appropriate for a company of PSX's size and complexity.
