Aviat Networks, Inc. (the Company) and Computershare Inc., as rights agent, entered into Amendment No. 2 to the Amended and Restated Tax Benefit Preservation Plan on February 27, 2026. This amendment extends the final expiration date of the Tax Benefit Preservation Plan (the Plan) from its previous term to March 3, 2029. The Plan, originally established on August 27, 2020, and previously amended on February 28, 2023, aims to protect the Company's ability to utilize its net operating losses, built-in losses, and other tax attributes (collectively, Tax Benefits). The Board of Directors views these Tax Benefits as highly valuable assets that are expected to benefit the Company and its stockholders. The Company intends to submit this Amendment for stockholder ratification at its 2026 annual meeting. If stockholder approval is not obtained, the Company anticipates terminating the Plan at the close of business on the date the voting results are certified.
