Dear Stockholders:
You are invited to attend the 2026 annual meeting of stockholders of Monolithic Power Systems, Inc. to be held on Thursday, June 11, 2026, at 10:00 a.m., Pacific Time (the “2026 Annual Meeting”). The 2026 Annual Meeting will be a virtual meeting. You will be able to attend the 2026 Annual Meeting online, vote and submit questions during the meeting by visiting http://meetnow.global/MAUDUJC. Please follow the instructions carefully on how to access and attend the virtual meeting in the “2026 Annual Meeting Attendance” section of this Proxy Statement.
It is important that your shares be represented and voted whether or not you plan to attend the 2026 Annual Meeting. We continue using the Securities and Exchange Commission rule that permits companies to furnish proxy materials to stockholders over the Internet. If you are viewing the Proxy Statement on the Internet, you may grant your proxy electronically over the Internet by following the instructions on the Notice Regarding the Availability of Proxy Materials previously mailed to you and the instructions listed on the Internet site. If you have received a paper copy of the Proxy Statement and proxy card, you may grant a proxy to vote your shares by completing and mailing the proxy card enclosed with the Proxy Statement, or you may grant your proxy electronically over the Internet or by telephone by following the instructions on the proxy card. If your shares are held in “street name,” which means shares held of record by a broker, bank, trust or other nominee, you should review the Notice Regarding the Availability of Proxy Materials or Proxy Statement and voting instruction form used by that firm to determine whether and how you will be able to submit your proxy by telephone or over the Internet. Submitting a proxy over the Internet, by telephone or by mailing a proxy card will ensure your shares are represented at the 2026 Annual Meeting.
Your vote is important, regardless of the number of shares that you own.
On behalf of the Board of Directors, I thank you for your participation. We look forward to your attendance on June 11, 2026.
Sincerely,
Michael Hsing
Chairman of the Board, President and Chief Executive Officer
