Fiscal 2025 Annual Meeting

Our Board of Directors set March 9, 2026 as the date of our Fiscal 2025 Annual Meeting of Stockholders (the “2025 Annual Meeting”). Stockholders of record at the close of business on January 15, 2026 will be entitled to notice of, and vote at the 2025 Annual Meeting.

Because the date of the 2025 Annual Meeting is changed by more than 30 days from the anniversary date of our Fiscal 2024 Annual Meeting of Stockholders, the Company is providing the due date for submission of any qualified stockholder proposal or qualified stockholder nominations for the 2025 Annual Meeting.

Eligible stockholders wishing to have a proposal for action by the stockholders at the 2025 Annual Meeting included in our proxy statement pursuant to Rule 14a-8 of the SEC’s proxy rules must submit such proposal at the principal offices of Comtech, and such proposal must be received by us not later than January 2, 2026, which the Company has determined to be a reasonable time before it expects to begin to print and send its proxy materials. Any such proposal must also meet the requirements set forth in the rules and regulations of the Securities and Exchange Commission in order to be eligible for inclusion in the proxy materials for the 2025 Annual Meeting, and must be addressed to Comtech Telecommunications Corp., Attention: Corporate Secretary, 305 N 54th Street, Chandler, AZ 85226.

Under our By-Laws, a stockholder nomination for election to our Board of Directors may not be made at the 2025 Annual Meeting unless notice (including all information required under Article II, Section 8 of our By- Laws) is delivered in person or mailed to Comtech and received by us not later than January 8, 2026.

In addition, a stockholder proposal (other than a nomination for election to our Board of Directors or a stockholder proposal that may be made pursuant to Rule 14a-8) may not be made at the 2025 Annual Meeting unless notice thereof (including all information required under Article II, Section 9 of our By-Laws) is delivered in person or mailed to Comtech and received by us not later than January 8, 2026.

In addition to satisfying the foregoing requirements under our By-Laws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act.
