CEO Michael Hsing received total compensation of approximately $19.9 million in 2025, which is elevated in absolute terms but is consistent with the company's exceptional performance — record revenue of $2.8 billion (up 26%), non-GAAP operating income of $989 million, and a 3-year total shareholder return of +258% that outperforms the peer group median by over 170 percentage points. The pay structure is strongly performance-oriented: base salary represents approximately 5% of total compensation, with the remaining 95% at risk through cash bonuses tied to non-GAAP operating income and equity awards (performance stock awards) tied to multi-year revenue growth and relative total shareholder return goals — well above the 50-60% variable pay standard required by policy. The prior year say-on-pay vote received 96% support, the company has a robust clawback policy in place, and the compensation committee made meaningful improvements in 2025 by adding a relative total shareholder return metric to equity awards in direct response to shareholder feedback.

EY has served since March 2019 (approximately 7 years), well below the 25-year tenure threshold that would raise independence concerns. Non-audit fees of $8,000 represent less than 1% of audit fees of $2,487,000 — far below the 50% ratio that would trigger an against vote. EY is a Big 4 firm fully appropriate for a company of MPWR's size and complexity. No material financial restatements attributable to audit failure are identified (the 2024 restatement noted in the filing relates to a deferred tax item and is not described as an audit failure).
