Re:        Calix, Inc.
Form 10-K for the Fiscal Year Ended December 31, 2023
Form 8-K filed April 22, 2024
File No. 001-34674

Dear Inessa Kessman, Robert Littlepage:

This letter is submitted on behalf of Calix, Inc. (“Calix” or “Company”) in response to the comment of the staff (the “Staff”) of the Division of Corporation Finance of the Securities and Exchange Commission (the “SEC”) in its letter dated July 2, 2024 in connection with the above-referenced filings.

For convenience, we have set forth in bold the text of the Staff’s comment below followed by the Company’s response.

Form 8-K filed April 22, 2024
Exhibit 99.2, page 15

1.     We note your response to prior comment 1. As the write-off of inventory and accrued liabilities related to excess components at suppliers related to your legacy product set appears to be a normal, recurring operating expense, please remove the non-GAAP adjustment for Inventory and component liability charges. Refer to Question 100.01 of the Division of Corporation Finance’s Compliance & Disclosure Interpretations on Non-GAAP Financial Measures.

Response:

The Company respectfully advises the Staff that, in future filings, we will remove the non-GAAP adjustment for inventory and component liability charges related to our legacy product set.
