This prospectus supplement updates and supplements the prospectus dated April 5, 2022 (as amended, the "Prospectus"), which forms a part of our Registration Statement on Form S-1 (No. 333-263923).

The shares included in this prospectus consist of shares of Common Stock that we have issued or that we may, in our discretion, elect to issue and sell to the Selling Securityholder, from time to time after the date of this prospectus, pursuant to a common stock purchase agreement we entered into with the Selling Securityholder on February 18, 2022 (the “Purchase Agreement”), in which the Selling Securityholder has committed to purchase from us, at our direction, up to $50,000,000 of our Common Stock, subject to terms and conditions specified in the Purchase Agreement. Concurrently with our execution of the Purchase Agreement on February 18, 2022, we issued 100,000 shares of Common Stock to the Selling Securityholder as consideration for its irrevocable commitment to purchase shares of our Common Stock at our election in our sole discretion, from time to time after the date of this prospectus, upon the terms and subject to the satisfaction of the conditions set forth in the Purchase Agreement. See the section titled “Committed Equity Financing” for a description of the Purchase Agreement and the section titled “Selling Securityholder” for additional information regarding the Selling Securityholder.


The Common Stock is listed on The Nasdaq Capital Market (“Nasdaq”) under the symbol “SRZN”. On January 5, 2023, the last reported sales price of the Common Stock as reported on Nasdaq was $0.56 per share.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On January 4, 2023, Surrozen, Inc. received a written notice from The Nasdaq Stock Market, LLC (“Nasdaq”) notifying us that on January 3, 2023, the average closing price of our common stock over the prior 30 consecutive trading days had fallen below $1.00 per share, which is the minimum average closing price required to maintain listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”).

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have 180 calendar days to regain compliance with the Minimum Bid Requirement (the “Grace Period”), subject to a potential 180 calendar day extension, as described below. To regain compliance, the closing bid price of our common stock must be at least $1.00 per share for a minimum of ten consecutive business days within the Grace Period.

If we do not achieve compliance with the Minimum Bid Requirement by July 3, 2023, the end of the Grace Period, we may be eligible for an additional 180 calendar day period to regain compliance. To qualify, we would be required to meet the continued listing requirement for the market value of our publicly held shares and all other Nasdaq initial listing standards, with the exception of the bid price requirement, and would need to provide written notice of our intention to cure the deficiency during the second compliance period. However, if it appears to Nasdaq staff that we will not be able to cure the deficiency, or if we do not meet the other listing standards, Nasdaq could provide notice that our common stock will be subject to delisting. In the event we receive notice that our common stock is being delisted, we would be entitled to appeal the determination to a Nasdaq Listing Qualifications Panel and request a hearing.

We intend to actively monitor the closing bid price of our common stock and will evaluate available options to regain compliance with the Minimum Bid Requirement. There can be no assurance that we will be able to regain compliance with the Minimum Bid Requirement or maintain compliance with the other listing requirements. The notice has no immediate effect on the listing or trading of our common stock, which will continue to be listed and traded on the Nasdaq Capital Market, subject to our compliance with the other Nasdaq listing requirements
