#### Audit Fees
KPMG audit fees for 2024 consist of fees billed or expected to be billed for professional services rendered for the audit of our annual consolidated financial statements for the year ended 2024, the audit of the effectiveness of our internal control over financial reporting and the review of our consolidated financial statements included in our Form 10-Q quarterly reports for the year ended 2024. KPMG audit fees for 2023 consist of actual fees for professional services rendered for the audit of our annual consolidated financial statements for the year ended 2023, the audit of the effectiveness of our internal control over financial reporting and the review of our consolidated financial statements included in our Form 10-Q quarterly reports for the year ended 2023. Audit fees also include services that are typically provided by the independent registered public accounting firm in connection with statutory and regulatory filings for our international subsidiaries for those years.

### Pre-Approval Policy and Procedures
Our Audit Committee pre-approves all audit and non-audit services provided by our independent registered public accounting firm. Our Audit Committee may delegate authority to one or more members of the Audit Committee to provide such pre-approvals, provided that such approvals are presented to the Audit Committee at a subsequent meeting. This policy is set forth in the charter of the Audit Committee and available under “Governance” in the Investor Relations section of our website at investor-relations.calix.com .
