Monolithic Power Systems is asking stockholders to vote at its virtual 2026 annual meeting on June 11, 2026. Stockholders of record at the close of business on April 15, 2026, when 49,129,267 shares of Common Stock were outstanding, may attend online, vote and submit questions.
Three main proposals will be presented: electing two Class I directors (Victor K. Lee and Jeff Zhou) for terms expiring in 2029, ratifying EY as independent registered public accounting firm for 2026, and approving on an advisory basis the compensation of named executive officers.
The proxy describes a largely independent, skills-diverse Board, a phased declassification so all directors stand for one-year terms by 2030, and a reduced 25% ownership threshold for stockholders to call special meetings. It also outlines ESG oversight through Board committees and a cross-functional steering committee.
Executive pay is heavily performance-based, with 2025 incentives tied to non-GAAP operating income, relative revenue growth and relative total stockholder return. In 2025 the company delivered revenue of $2.79 billion, up 26.4% from 2024, and increased its annual dividend to $6.24 per share, with a further raise to $8.00 per share annually approved for 2026.
