CUSIP No. 86889P 109 13D

**Explanatory Note:** 

This joint statement on Schedule 13D/A (this "Statement") is filed with respect to the Common Stock, par value $0.0001 per share ("Common Stock"), of Surrozen, Inc., a Delaware corporation (the "Issuer").

This Amendment No. 1. (this "Amendment") supplements and amends the Schedule 13D relating to the Common Stock of the Issuer that was filed with the Commission on August 23, 2021 (the "Original Schedule 13D"). This Amendment is being filed to update the aggregate percentage of the Common Stock owned by the Reporting Persons due to decreases in the total number of shares of Common Stock outstanding from time to time since the date of the filing of the Original Schedule 13D and not in connection with a disposition of any shares by the Reporting Persons. Such decreases in total number of shares of Common Stock outstanding resulted in an increase of over one percent (1%) in the aggregate percentage ownership reported by the Reporting Persons in the Original Schedule 13D. Only those items that are reported are hereby amended; all other items reported in the Original Schedule 13D remain unchanged. Capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Original Schedule 13D. Information given in response to each item shall be deemed incorporated by reference in all other items as applicable.

This information reported is based on a total of (i) 35,122,863 shares of Common Stock outstanding as of November 10, 2022, as reported in the Issuer's Form 10-Q minus (ii) 5,382,499 shares of Common Stock subsequently repurchased by the Issuer as reported in the Issuer's Form 8-K plus (iii) 78,272 shares underlying warrants to purchase shares of Common Stock held by TCG III LP which are exercisable within 60 days of this Statement and (iv) 88,394 shares underlying warrants to purchase shares of Common Stock held by TCG III-A LP which are exercisable within 60 days of this Statement.

------

**SIGNATURE** 

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
