Form 10-K for the Fiscal Year Ended December 31, 2022
Management's Discussion and Analysis of Financial Condition and Results of Operations
Non-GAAP Financial Measures, page 46
1.We note from your response to prior comment 1 that payments under the Vesting Agreements require continued employment with the company and are subject to forfeiture upon termination. Considering such arrangements require continued employment and the amounts will be paid in cash, it remains unclear how such charges are not a normal, recurring cash operating expenses. Accordingly, please remove these adjustments from your non-GAAP measures.
The Company acknowledges the Staff’s comment and confirms that it will remove this adjustment from its non-GAAP financial measures in future filings.

If you have further questions or comments regarding, or requiring further information or clarification of, any of the responses provided in this letter, please do not hesitate to contact me at (415) 828-5713 or in my absence, Aman Singh at (212) 430-2767.
