**SUPPLEMENT TO DEFINITIVE PROXY STATEMENT DATED OCTOBER 16, 2025** 

**FOR THE 2025 ANNUAL MEETING OF STOCKHOLDERS**

**TO BE HELD ON Wednesday, December 10, 2025**

This supplement (the "Supplement") amends the Proxy Statement of AmpliTech Group, Inc. (the "Company"), dated October 16, 2025 (the "Proxy Statement") filed with the Securities and Exchange Commission (the "SEC") on October 16, 2025, in connection with the Company's 2025 Annual Meeting of Stockholders to be held on Wednesday, December 10, 2025, at 5:00 p.m. Eastern Time, in person at the offices of Company, 155 Plant Avenue, Hauppauge, NY, 11788, and any adjournment or postponement thereof (the "Annual Meeting").

The Company is issuing this Supplement to correct a typographical error in the Proxy Statement regarding the number of shares of common stock outstanding as of the record date on October 15, 2025 (the "Record Date"). In the Proxy Statement, the number of issued and outstanding shares of the Company's common stock as of the Record Date was incorrectly stated as 20,631,595. The correct number of shares issued and outstanding as of that date was 20,638,095.

Except as specifically described in this Supplement, all other information set forth in the Proxy Statement remains unchanged and should be considered in voting your shares. This Supplement does not change the proposals to be acted on at the Annual Meeting, the Record Date or the date, time, or location of the Annual Meeting. Stockholders who have already submitted proxies or voting instructions do not need to take any further action, unless they wish to change their vote
