On October 21, 2024, Mr. James C. Moyer resigned from the Board of Directors (the ?Board?) of Monolithic Power Systems, Inc. and as a result, the Board decreased the total number of its authorized directors from eight to seven. To achieve a more equal balance of membership among the classes of directors of the Company, the Board has reduced the total number of authorized directors in Class II to two, increased the total number of authorized directors in Class I to two and appointed Mr. Jeff Zhou as a Class I director with a term set to expire at the 2026 annual meeting of stockholders. On October 21, 2024, Mr. Zhou resigned as a Class II director, effective immediately prior to his reappointment to the Board as a Class I director.

For all other purposes, Mr. Zhou?s service on the Board is deemed to have continued uninterrupted. The Board now consists of two Class I directors whose term will expire at the annual meeting of stockholders in 2026; two Class II directors whose term will expire at the annual meeting of stockholders in 2027; and three Class III directors whose term will expire at the annual meeting of stockholders in 2025. In addition, Mr. Zhou continues to serve on the Company?s Compensation Committee and Audit Committee.
