#### PROPOSAL NO. 3
<div align='center'>APPROVAL OF THE MATCHING COMPONENT OF THE CALIX, INC. STOCK PURCHASE AND MATCHING PLAN</div>

We are asking our stockholders to approve the Calix, Inc. Stock Purchase and Matching Plan (the “Stock Purchase and Matching Plan”), which constitutes an amendment and restatement of the Calix, Inc. Third Amended and Restated 2017 Nonqualified Employee Stock Purchase Plan (the “Nonqualified ESPP”), to establish the number of shares of our common stock that may be issued under the matching component of the Stock Purchase and Matching Plan. Our Board, upon recommendation of our Talent and Compensation Committee, approved the establishment of 2,923,400 shares authorized for the matching component of the Stock Purchase and Matching Plan in March 2025, including 1,250,000 additional shares subject to stockholder approval. Our Board, upon recommendation of our Talent and Compensation Committee, approved the corresponding reduction in the number of shares available for issuance under the Calix, Inc. Employee Stock Purchase Plan (our tax qualified ESPP) by 2,500,000 shares, subject to stockholder approval of this Proposal No. 3.

The purpose of the Stock Purchase and Matching Plan is to assist our employees, excluding our executive officers and certain members of senior management, in acquiring a stock ownership interest in the Company pursuant to a plan which is intended to increase employee proprietary interest in our success and to encourage them to remain in the employment of the Company. We believe that the Stock Purchase and Matching Plan aligns employee interests with that of our stockholders, is an important component of the benefits we offer to our employees and serves as a key recruiting and retention tool in a competitive market. In the past two years, we averaged approximately 60.0% employees participating in the Nonqualified ESPP in each purchase period.

There are two components to the Stock Purchase and Matching Plan, a purchase component and a matching component. Under the purchase component, we have reserved 2,923,400 shares of our common stock for issuance and employees of our company and its subsidiaries may purchase shares of our common stock for the closing trading price of our common stock on the date of purchase. Under the matching component, we have reserved 2,923,400 shares of our common stock, subject to stockholder approval of this Proposal No. 3, and
