#### CALIX, INC.
<div align='center'>FOURTH AMENDED AND RESTATED 2019 EQUITY INCENTIVE AWARD PLAN</div>

## ARTICLE 1.

### PURPOSE
The purpose of the Calix, Inc. Fourth Amended and Restated 2019 Equity Incentive Award Plan (as it may be amended or restated from time to time, the “Plan”) is to promote the success and enhance the value of Calix, Inc. (the “Company”) by linking the individual interests of the members of the Board, Employees and Consultants to those of Company stockholders and by providing such individuals with an incentive for outstanding performance to generate superior returns to Company stockholders. The Plan is further intended to provide flexibility to the Company in its ability to attract, incentivize and retain the services of members of the Board, Employees and Consultants upon whose judgment, interest and special effort the successful conduct of the Company’s operation is largely dependent. The Plan amends and restates the Third Amended and Restated 2019 Equity Incentive Award Plan approved by our stockholders in May 2023 (the “Prior Plan”) in its entirety, subject to stockholder approval of this Plan at the annual meeting of the Company’s stockholders in 2025. In the event the Company’s stockholders fail to approve the Plan as set forth herein at the annual meeting of the Company’s stockholders in 2025, then this Plan shall be deemed void ab initio and the Prior Plan shall continue in effect in accordance with its terms.
