SURROZEN, INC.

Notes to the Unaudited Condensed Consolidated Financial Statements

Note 1. Organization and Business

Organization

Surrozen, Inc., or the Company, formerly known as Consonance-HFW Acquisition Corp., or Consonance, is a clinical stage biotechnology company committed to discovering and developing drug candidates to selectively modulate the Wnt pathway, a critical mediator of tissue repair, in a broad range of organs and tissues, for human diseases. The Company, a Delaware corporation, is located in South San Francisco, California.

Business Combination and Private Investment in Public Entity Financing

Consonance was a blank check company incorporated as a Cayman Islands exempted company on August 21, 2020. It was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses.

On August 11, 2021, Consonance consummated a business combination, or the Business Combination, among Consonance, Perseverance Merger Sub Inc., a subsidiary of Consonance, and Surrozen, Inc., or Legacy Surrozen, a Delaware company incorporated on August 12, 2015. Upon closing of the Business Combination, Consonance became a Delaware corporation and was renamed to Surrozen, Inc., Legacy Surrozen, was renamed to Surrozen Operating, Inc., and Legacy Surrozen continued as a wholly-owned subsidiary of the Company. See Note 3, “Recapitalization” for additional details.

In May 2022, Surrozen Netherlands, B.V. was incorporated and located in Rotterdam, Netherlands as a wholly-owned subsidiary of Surrozen Operating, Inc.

Liquidity

The Company has incurred net losses since inception. The Company has historically financed the operations primarily through private placements of redeemable convertible preferred stock. As of September 30, 2022, the Company had cash, cash equivalents and marketable securities of $78.4 million. As of September 30, 2022, the Company had an accumulated deficit of approximately $177.9 million. The Company expects operating expenses to continue to increase in connection with our ongoing clinical studies and anticipates the need to raise additional capital to continue to execute its long-range business plan.

In October 2022, the Company executed a Collaboration and License Agreement, or CLA, with Boehringer Ingelheim International GmbH, or BI, pursuant to which the Company is eligible to receive a non-refundable upfront payment of $12.5 million (see Note 11). The Company expects to receive approximately $10.5 million of the upfront payment in the fourth quarter of 2022 and the remaining $2.0 million during the first six months of 2023.

Management believes that the existing cash, cash equivalents, and marketable securities, plus the gross cash proceeds of $12.5 million that will be received pertaining to the CLA, before deducting the fees of $1.3 million to be paid to Stanford and The Regents of the University of California (see Note 11), are sufficient for the Company to continue operating activities for at least the next 12 months from the date of issuance of its unaudited condensed consolidated financial statements. However, if the Company’s anticipated cash burn is greater than anticipated, the Company could use its capital resources sooner than expected which may result in the need to reduce future planned expenditures and/or raise additional capital to continue to fund the operations.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The Company’s unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP, and pursuant to the regulations of the U.S. Securities and Exchange Commission, or SEC. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted and accordingly, the condensed consolidated balance sheet as of December 31, 2021 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of the Company’s consolidated

6

financial statements. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ended December 31, 2022 or for any other interim period or future year.

The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated.

The Business Combination discussed in Note 1 was accounted for as a reverse recapitalization with Legacy Surrozen as the accounting acquirer and Consonance as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the unaudited condensed consolidated financial statements represents the accounts of Legacy Surrozen at their historical cost as if Legacy Surrozen is the predecessor to the Company. The unaudited condensed consolidated financial statements following the closing of the Business Combination reflect the results of the combined entity’s operations. All issued and outstanding common stock, redeemable convertible preferred stock and stock awards of Legacy Surrozen and per share amounts contained in the unaudited condensed consolidated financial statements for the periods presented prior to the closing of the Business Combination on August 11, 2021 have been retroactively restated to reflect the exchange ratio established in the Business Combination. See Note 3, “Recapitalization” for additional details.

The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 28, 2022.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions made in the accompanying unaudited condensed consolidated financial statements include, but are not limited to, certain accrued expenses for research and development activities, the fair value of common stock prior to the Business Combination, stock-based compensation expense and income taxes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could materially differ from those estimates.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to significant concentration of credit risk, consist of cash, cash equivalents and marketable securities. The Company's cash is held by one financial institution that management believes is creditworthy. Such deposits held with the financial institution may at times exceed federally insured limits, however, its exposure to credit risk in the event of default by the financial institution is limited to the extent of amounts recorded on the unaudited condensed consolidated balance sheets. The Company performs evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company's policy is to invest cash in institutional money market funds and marketable securities with high credit quality to limit the amount of credit exposure. The Company currently maintains a portfolio of cash equivalents and marketable securities in a variety of securities, including money market funds, U.S. government bonds, commercial paper and corporate debt securities. The Company has not experienced any realized losses on its cash equivalents and marketable securities.

Marketable Securities

The Company invests its excess cash in U.S. government bonds, commercial paper and corporate debt securities. All marketable securities have been classified as available-for-sale and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. The Company does not buy or hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity and return. From time to time, the Company may sell certain securities, but the objectives are generally not to generate profits on short-term differences in price.

Short-term marketable securities have maturities less than or equal to one year as of the balance sheet date. Long-term marketable securities have maturities greater than one year as of the balance sheet date. These marketable securities are carried at estimated fair value with unrealized holding gains or losses included in accumulated other comprehensive loss in stockholders’ equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Interest income is recognized in the unaudited condensed consolidated statements of operations and comprehensive loss when earned.

7

The Company periodically evaluates its available-for-sale marketable securities for impairment. When the fair value of a marketable security is below its amortized cost basis, the amortized cost is reduced to its fair value if it is more likely than not that the Company is required to sell the impaired security before recovery of its amortized cost, or the Company has the intention to sell the security. If neither of these conditions are met, the Company determines whether the impairment is due to credit losses by comparing the present value of the expected cash flows of the security with its amortized cost basis. The amount of impairment recognized is limited to the excess of the amortized cost basis over the fair value of the security. An allowance for credit losses for the excess of amortized cost basis over the expected cash flows, if any, is recorded in other income (expense), net on the unaudited condensed consolidated statements of operations. Impairment losses that are not credit-related are included in accumulated other comprehensive loss in stockholders’ equity.

Warrant Liabilities

The Company's Public Warrants, Private Placement Warrants and PIPE Warrants were classified as liabilities (see Note 9). At the end of each reporting period, any changes in fair value during the period are recognized in other income, net within the unaudited condensed consolidated statements of operations and comprehensive loss. The Company will continue to adjust the warrant liabilities for changes in the fair value until the earlier of a) the exercise or expiration of the warrants or b) the redemption of the warrants, at which time such warrants will be reclassified to additional paid-in capital.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss attributable to common stock by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive securities. Since the Company was in a loss position for the periods presented, basic net loss per share is the same as diluted net loss per share as the effects of potentially dilutive securities are antidilutive. The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share of common stock as of the periods presented because including them would have been antidilutive (in thousands):

	September 30,
	2022		2021
Options outstanding		3,811		1,701
Unvested restricted stock		117		178
Unvested common stock subject to repurchase		29		102
Warrants to purchase common stock		7,219		7,219
Total		11,176		9,200

Note 3. Recapitalization

On August 11, 2021, Consonance consummated the Business Combination (see Note 1). Immediately after the consummation of the Business Combination, certain investors subscribed for and purchased an aggregate of 12.0 million units, each consisting of one share of the Company’s common stock and one-third of one redeemable warrant, for a purchase price of $10.00 per unit through a private investment in public entity financing, or PIPE Financing. In connection with the Business Combination and PIPE Financing, Legacy Surrozen received the aggregate cash consideration of $128.8 million, after deducting the transaction fees incurred by Consonance. The cash consideration was comprised of $8.6 million in proceeds from issuance of common stock upon the closing of the Business Combination and $120.2 million in proceeds from the PIPE Financing. The Company incurred transaction costs of $6.3 million, consisting of legal, accounting and other professional services directly related to the Business Combination, $0.4 million of which were allocated to the warrant liabilities assumed and recognized as other expenses when incurred. The remaining $5.9 million were recorded as a reduction of additional paid-in capital in the unaudited condensed consolidated balance sheet. Legacy Surrozen was deemed the accounting acquirer in the Business Combination and the Business Combination was accounted for as a reverse recapitalization based on the following predominant factors:

•Legacy Surrozen’s stockholders have the greatest voting interest in the Company;

•The Company’s board and senior management are primarily composed of individuals associated with Legacy Surrozen; and

•Legacy Surrozen is the larger entity based on historical operating activity and has the larger employee base at the time of the Business Combination.

Accordingly, for accounting purposes, the reverse recapitalization was treated as the equivalent of Legacy Surrozen issuing stock for the net assets of Consonance, accompanied by a recapitalization. The net assets of Consonance are stated at historical cost, with no goodwill or other intangible assets recorded.

8

Pursuant to the business combination agreement, upon the closing of the Business Combination, (i) each share of redeemable convertible preferred stock of Legacy Surrozen (on an as converted to common stock basis) and each share of common stock of Legacy Surrozen, whether vested or unvested, was converted into 0.175648535 shares of the Company’s common stock and (ii) each outstanding option to purchase common stock of Legacy Surrozen was converted into an option to purchase shares of the Company’s common stock based on an exchange ratio of 0.175648535, or the Exchange Ratio, with corresponding adjustments to the exercise price. All issued and outstanding common stock, preferred stock and stock awards of Legacy Surrozen and corresponding capital amounts contained in the unaudited condensed consolidated financial statements for the periods presented prior to the closing of the Business Combination have been retroactively restated to reflect the conversion.

Note 4. Fair Value Measurement

(1)Money market funds are included in cash and cash equivalents on the unaudited condensed consolidated balance sheets as of September 30, 2022 and December 31, 2021.

(2)See the definition and discussion of Public Warrants, Private Placement Warrants and PIPE Warrants in Note 9.

There were no changes to the valuation methods utilized and there were no transfers of financial instruments between Level 1, Level 2, and Level 3 during the nine months ended September 30, 2022.

Corporate bonds, commercial paper, foreign bonds and government bonds are classified as Level 2 as they were valued based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets.

9

The Public Warrants are classified as Level 1 due to the use of an observable market quote in an active market. The Private Placement Warrants and PIPE Warrants are classified as Level 2 due to the use of observable market data for identical or similar liabilities. The fair value of each Private Placement Warrant and PIPE Warrant was determined to be consistent with that of a Public Warrant because the Private Placement Warrants and PIPE Warrants are also subject to the make-whole redemption feature, which allows the Company to redeem both types of warrants on similar terms when the stock price is in the range of $10 to $18 per share.

The following tables provide the Company’s marketable securities by security type (in thousands):

	September 30, 2022

Total long-term marketable securities	$	21,753	$	—	$	(98	)	$	21,655

The following table indicates the length of the time that individual securities have been in a continuous unrealized loss position as of September 30, 2022 (dollars in thousands):

			Less Than 12 Months
	Number of Investments		Fair Value		Unrealized Losses
Corporate bonds		7	$	16,946	$	60
Government bonds		3		17,695		364
Total		10	$	34,641	$	424

As of September 30, 2022 and December 31, 2021, all short-term marketable securities had maturities of one year or less. There have been no significant realized gains or losses on the short-term and long-term marketable securities during the three and nine months ended September 30, 2022 and 2021. The Company periodically reviews the available-for-sale investments for other-than-temporary impairment loss. All investments with unrealized losses have been in a loss position for less than 12 months. The Company determined that the unrealized loss was primarily attributed to changes in current market interest rates and not to credit quality. The Company does not intend to sell the marketable securities that are in an unrealized loss position, nor is it more likely than not that the Company will be required to sell the marketable securities before the recovery of the amortized cost basis, which may be at maturity. As a result, the Company did not recognize any other-than-temporary impairment losses as of September 30, 2022.

Note 6. License Agreements

Stanford License Agreements

In March 2016, the Company entered into a license agreement with Stanford University, or the 2016 Stanford Agreement, which was amended in July 2016, October 2016 and January 2021, pursuant to which the Company obtained from Stanford a worldwide, exclusive, sublicensable license under certain patents, rights, or licensed patents and technology related to its engineered Wnt surrogate molecules to make, use, import, offer to sell and sell products that are claimed by the licensed patents or that use or incorporate such technology, or licensed products, for the treatment, diagnosis and prevention of human and veterinary diseases. The Company agreed to pay Stanford an aggregate of up to $0.9 million for the achievement of specified development and regulatory milestones, and an aggregate of up to $5.0 million for achievement of specified sales milestones. Stanford is also entitled to receive royalties from the Company equal to a very low single digit percentage of the Company’s and its sublicensees’ net sales of licensed products that are covered by a valid claim of a licensed patent. Additionally, the Company agreed to pay Stanford a low double-digit percentage of non-royalty sublicense consideration received by the Company in connection with any sublicense granted to a third-party and, if the Company is acquired, a one-time change of control fee in the low six figures.

In June 2018, the Company entered into another license agreement with Stanford, or the 2018 Stanford Agreement, pursuant to which the Company obtained from Stanford a worldwide, exclusive, sublicensable license under certain patent rights related to its surrogate R-spondin proteins, or the licensed patents, to make, use, import, offer to sell and sell products that are claimed by the licensed patents, or licensed products, for the treatment, diagnosis and prevention of human and veterinary diseases, or the exclusive field. Additionally, Stanford granted the Company a worldwide, non-exclusive, sublicensable license under the licensed patents to make and use licensed products for research and development purposes in furtherance of the exclusive field and a worldwide, non-exclusive license to make, use and import, but not to offer to sell or sell, licensed products in any other field of use. The Company agreed to pay Stanford an aggregate of up to $0.4 million for the achievement of specified development and regulatory milestones. Stanford is also entitled to receive royalties from the Company equal to a sub-single digit percentage of the Company’s and its sublicensees’ net sales of licensed products. Additionally, Stanford is entitled to receive a one-time payment in the low six figures for each sublicense of the licensed patents that the Company grants to a third party and, if the Company is acquired, a one-time nominal change of control fee.

11

For the three and nine months ended September 30, 2022, the Company incurred de minimis and $0.1 million research and development expenses under the Stanford agreements. For the three and nine months ended September 30, 2021, the Company incurred de minimis research and development expenses under the Stanford agreements. No milestones have been achieved as of September 30, 2022.

UCSF License and Option Agreements

In September and October 2016, the Company entered into two separate license and option agreements with The Regents of the University of California, or the UCSF Agreements, pursuant to which the Company obtained exclusive licenses from UCSF for internal research and antibody discovery purposes and an option to negotiate with UCSF to obtain an exclusive license under UCSF’s rights in the applicable library to make, use, sell, offer for sale and import products incorporating antibodies identified or resulting from the Company’s use of such library, or licensed products.

In January 2020, the Company amended and restated the UCSF Agreements to provide non-exclusive licenses to make and use a certain human Fab naïve phage display library and to make and use a certain phage display llama VHH single domain antibody library for internal research and antibody discovery purposes and an option to negotiate with UCSF to obtain a non-exclusive commercial license under UCSF’s rights in the applicable library to make, use, sell, offer for sale and import products incorporating antibodies identified or resulting from the Company’s use of such library, or licensed products.

In March 2022, the Company exercised the option under the UCSF Agreements and entered into a non-exclusive commercial license agreement to make and use licensed products derived from the phage display llama VHH single domain antibody library. Under the commercial license agreement, the Company paid UCSF a nominal license issue fee and agreed to pay a nominal annual license maintenance fee, five- to six-digit payments per licensed product upon achievement of a regulatory milestone, nominal minimum annual royalties, and earned royalties equal to a sub-single digit percentage of the Company’s and the Company’s sublicensees’ net sales of licensed products.

For the three and nine months ended September 30, 2022, the Company incurred de minimis and $0.1 million research and development expenses under the UCSF Agreements and the commercial license agreement. For the three and nine months ended September 30, 2021, the Company incurred de minimis research and development expenses under the UCSF Agreements and the commercial license agreement. No milestones have been achieved as of September 30, 2022.

Distributed Bio Subscription Agreement

In September 2016, the Company entered into, and in January 2019, the Company amended, an antibody library subscription agreement with Charles River Laboratories International, Inc., formerly known as Distributed Bio, Inc., or the Distributed Bio Agreement, in which the Company obtained from Distributed Bio a non-exclusive license to use Distributed Bio’s antibody library to identify antibodies directed to an unlimited number of the Company’s proprietary targets and to make, use, sell, offer for sale, import and exploit products incorporating the antibodies that the Company identifies, or licensed products. The Company agreed to pay Distributed Bio an annual fee in the low six figures after the first three years. Additionally, the Company agreed to pay Distributed Bio an aggregate of $5.9 million for each licensed product that achieves specified development, regulatory and commercial milestones and royalties equal to a very low single digit percentage of the Company’s and its sublicensees’ net sales of licensed products. The Company’s obligation to pay royalties will end for each licensed product ten years after its first commercial sale.

For the three and nine months ended September 30, 2022, the Company incurred $0.1 million research and development expenses under the Distributed Bio Agreement as the Company achieved a milestone with regard to the initiation of the Phase 1 clinical trial for SZN-1326 in May 2022. For the three and nine months ended September 30, 2021, the Company incurred de minimis research and development expenses under the Distributed Bio Agreement.

Note 7. Commitments and Contingencies

Lease Agreements

In August 2016, the Company entered into a lease agreement for office and lab space, which consists of approximately 32,813 square feet of rental space in South San Francisco, California. The office space lease is classified as an operating lease. The initial lease term commenced in May 2017 and ends in April 2025, with rent payments escalating each year. The Company has options to extend the lease for additional years, but the exercise of the option was not reasonably certain. In connection with the lease, the Company maintains a letter of credit for the benefit of the landlord in the amount of $0.4 million, which is recorded as restricted cash in the unaudited condensed consolidated balance sheets.

12

In January 2020, the Company entered into a lease agreement for a term of 18 months commencing June 2020 for approximately 6,478 square feet of office space. This office space lease, which was amended in September 2021, was classified as an operating lease and expired in June 2022.

The operating lease expense for the three and nine months ended September 30, 2022 and 2021 was $0.4 million, $1.5 million, $0.5 million and $1.5 million, respectively.

Aggregate future minimum rental payments under the operating leases as of September 30, 2022, were as follows (in thousands):

Remaining three months ending December 31, 2022	$	636
Year ending December 31, 2023		2,596
Year ending December 31, 2024		2,670
Year ending December 31, 2025		891
Total lease payments		6,793
Less: Imputed interest		(677	)
Operating lease liabilities	$	6,116

Note 8. Stockholders’ Equity

Equity Purchase Agreement

In February 2022, the Company entered into the Equity Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park is obligated to purchase up to $50.0 million of the Company’s common stock with a maximum of 7,003,383 shares from time to time at the Company’s sole discretion over a 36-month period commencing on April 27, 2022. The Company also entered into a registration rights agreement with Lincoln Park pursuant to which the Company filed with the SEC the registration statement to register for resale under the Securities Act of 1933, as amended, the shares of common stock that have been or may be issued to Lincoln Park under the Equity Purchase Agreement. The registration statement was effective on April 5, 2022.

Upon execution of the Equity Purchase Agreement, the Company issued 0.1 million shares of common stock to Lincoln Park with the fair value of $0.3 million as consideration for Lincoln Park’s commitment to purchase the Company’s common stock, which was included in other income (expense), net on the unaudited condensed consolidated statements of operations and comprehensive loss. In the event that the Company sells its common stock under the Equity Purchase Agreement for an aggregate price equal to or greater than $30.0 million, the Company shall pay an additional commitment fee of $0.1 million in cash to Lincoln Park.

As contemplated by the Equity Purchase Agreement, and so long as the closing price of the Company’s common stock exceeds $1.00 per share, the Company may direct Lincoln Park, at its sole discretion, to purchase up to 30,000 shares of its common stock, or the Regular Purchase Share Limit, on any business day at a purchase price per share equal to the lower of: (i) the lowest price of the Company’s common stock on the applicable purchase date and (ii) the average of the 3 lowest closing prices of the Company’s common stock during the 10 consecutive business days preceding such purchase date. The Regular Purchase Share Limit may be increased to up to 35,000 shares and 40,000 shares if the closing price of the Company’s common stock is not below $10.00 per share and $12.00 per share, respectively. Any single purchase of the Company’s common stock shall not exceed $3.5 million.

The Company may also direct Lincoln Park to purchase additional shares no less than the Regular Purchase Share Limit and no greater than 500,000 shares at a purchase price per share equal to 96% of the lower of (i) the closing price of the Company’s common stock on the purchase date and (ii) the volume weighted average price of the Company’s common stock on the purchase date.

As of September 30, 2022, the Company has not sold any shares of common stock under the Equity Purchase Agreement.

Note 9. Common Stock Warrants

In connection with the Business Combination, Legacy Surrozen, as the accounting acquirer, was deemed to assume warrants held by Consonance’s stockholders, or the Public Warrants, and warrants held by Consonance's sponsor, or the Private Placement Warrants. In addition, in the PIPE Financing, certain investors subscribed for and purchased an aggregate of 12.0 million units, each consisting of one share of the Company’s common stock and one-third of one redeemable warrant, or PIPE Warrants. All of these warrants were outstanding as of September 30, 2022. The following table sets forth the common stock warrants outstanding as of September 30, 2022 (in thousands, except exercise price per warrant):

Type	Classification	Expiration Date	Exercise Price per Warrant		Number of Warrants		Fair Value
Public Warrants	Liability	August 12, 2026	$	11.50		3,067	$	566
Private Placement Warrants	Liability	August 12, 2026		11.50		145		27
PIPE Warrants	Liability	August 12, 2026		11.50		4,007		739
Total						7,219	$	1,332

Public Warrants

Each whole Public Warrant entitles the holder to purchase one share of the Company’s common stock at a price of $11.50 per share, at any time commencing on November 23, 2021 and terminating at the earlier of August 12, 2026 or upon redemption or liquidation. The exercise price and number of shares issuable upon exercise of the Public Warrants may be adjusted in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. The Company would not be obligated to deliver any shares of common stock pursuant to the exercise of a Public Warrant and would have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act with respect to the common stock underlying the Public Warrants is then effective. The registration statement on Form S-1 to register for resale under the Securities Act of 1933, as amended, was effective in November 2021. The Company shall use its efforts to maintain the effectiveness of the registration statement until the expiration or redemption of the Public Warrants. If the Company fails to have maintained an effective registration statement, the Public Warrant holders have the right to exercise the Public Warrants on a cashless basis until such time as there is an effective registration statement.

The Company may redeem the outstanding Public Warrants at a price of $0.01 per warrant if the closing price of common stock equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction). Additionally, the Company may redeem the outstanding Public Warrants at a price of $0.10 per warrant if the closing price of common stock equals or exceeds $10.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction). Notice of redemption shall be mailed to the Public Warrant holders no less than 30 days prior to the redemption date, or the Redemption Period. If the closing price of common stock equals or exceeds $10.00 per share and is less than $18.00 per share, during the Redemption Period, the Public Warrant holders may elect to exercise their Public Warrants on a cashless basis based on a make-whole table.

In no event will the Company be required to net cash settle the Public Warrants. The Public Warrant holders do not have the rights or privileges of common stockholders and any voting rights until they exercise their Public Warrants and receive common stock.

Private Placement Warrants

The Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants, except that so long as they are held by Consonance's sponsor or any of its permitted transferees, the Private Placement Warrants: (i) may be exercised for cash or on a cashless basis, (ii) may not be transferred, assigned or sold until 30 days after the completion of the Business Combination, (iii) shall not be redeemable by the Company if the closing price of common stock equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction) and (iv) shall only be redeemable if the closing price of common stock is less than $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction). If the Private Placement Warrants are held by holders other than Consonance's sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the Public Warrants.

PIPE Warrants

Each whole PIPE Warrant entitles the holder to purchase one share of the Company’s common stock at a price of $11.50 per share, at any time commencing on November 23, 2021 and terminating on August 12, 2026. The PIPE Warrants are the same in all respects as the Public Warrants except that the PIPE Warrants are not redeemable before August 12, 2022.

14

Classification

The Public Warrants, Private Placement Warrants and PIPE Warrants are not considered indexed to the Company’s common stock as certain provisions of the warrant agreements could change the settlement amount of these warrants. As a result, they were classified as liabilities and recorded at fair value with subsequent change in their respective fair value recognized in the other income (expense), net within the unaudited condensed consolidated statements of operations and comprehensive loss at each reporting date. See Note 4 for the discussion of warrant valuations.

Note 10. Stock-Based Compensation Plan

The Company maintains the 2021 Equity Incentive Plan, or the 2021 Plan, which provides for the granting of stock awards to employees, directors and consultants. Options granted under the 2021 Plan may be either incentive stock options, or ISOs, or nonqualified stock options, or NSOs. Options granted under the 2021 Plan expire no later than 10 years from the date of grant. Options under the 2021 Plan generally vest 25% upon one year of continued service to the Company, with the remainder in monthly increments over three additional years. As of September 30, 2022, there were 4.5 million shares of common stock available for issuance under the 2021 Plan.

The Company adopted the 2021 Employee Stock Purchase Plan, or the ESPP, in August 2021. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to plan limitations. An offering period under the ESPP consists of four six-month purchase periods, unless otherwise determined by the Company. The eligible employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the purchase day. As of September 30, 2022, there were 0.9 million shares of common stock available for issuance under the ESPP. No shares have been issued under the ESPP as of September 30, 2022.

Stock-based compensation expense under the ESPP is measured at the beginning of the offering period using the Black-Scholes option-pricing model and recognized on a straight-line basis over the offering period.

Stock Options

A summary of stock option activity is set forth below:

	Options outstanding
						Weighted
				Weighted		Average		Aggregate
	Number of			Average		Remaining		Intrinsic
	Options			Exercise		Contractual Life		Value
	(In thousands)			Price		(In years)		(In thousands)
Outstanding – December 31, 2021		1,794		$	6.31		8.43
Granted		2,106			3.32
Forfeited		(77	)		6.18
Expired		(12	)		5.92
Outstanding – September 30, 2022		3,811			4.66		8.65	$	602
Exercisable – September 30, 2022		1,194			4.17		7.47		574

The aggregate intrinsic values of options outstanding and exercisable are the differences between the exercise price of the options and the fair value of the Company’s common stock at September 30, 2022.

During the nine months ended September 30, 2022, the Company granted options with a weighted-average grant-date fair value of $2.31 per share.

Overview

We are discovering and developing biologic drug candidates to selectively modulate the Wnt pathway, a critical mediator of tissue repair, in a broad range of organs and tissues, for human diseases. Building upon the seminal work of our founders and scientific advisors who discovered the Wnt gene and key regulators of the Wnt pathway, we have made breakthrough discoveries that we believe will overcome previous limitations in harnessing the potential of Wnt biology. These breakthroughs enable us to rapidly and flexibly design tissue-targeted therapeutics that modulate Wnt signaling. As a result of our discoveries, we are pioneering the selective activation of Wnt signaling, designing and engineering Wnt pathway mimetics, and advancing tissue-specific Wnt candidates.

Our lead product candidates are multi-specific, antibody-based therapeutics that mimic the roles of naturally occurring Wnt or R-spondin proteins, which are involved in activation and enhancement of the Wnt pathway, respectively. Given Wnt signaling is essential in tissue maintenance and regeneration throughout the body, we have the potential to target a wide variety of severe diseases, including certain diseases that afflict the intestine, liver, retina, cornea, lung, kidney, cochlea, skin, pancreas and central nervous system. In each of these areas, we believe our approach has the potential to change the treatment paradigm for the disease and substantially impact patient outcomes.

Our strategy is to exploit the full potential of Wnt signaling by identifying disease states responsive to Wnt modulation, design tissue-specific therapeutics, and advance candidates into clinical development in targeted indications with high unmet need. Our unique approach and platform technologies have led to the discovery and advancement of two lead product candidates.

We initiated a Phase 1 clinical trial in the second quarter of 2022 for SZN-1326, our candidate in development for moderate to severe inflammatory bowel disease, or IBD, with ulcerative colitis, or UC, as our first proposed indication. SZN-1326, a Fzd5 targeted bi-specific antibody, is the first development candidate designed using Surrozen’s SWAP™ technology and targets the Wnt-signaling pathway in the intestinal epithelium. In preclinical animal models of acute and chronic colitis, SZN-1326 has been shown to transiently activate Wnt signaling in the diseased intestine, stimulate intestinal epithelial regeneration, reduce inflammation and reduce disease activity with no treatment related adverse effects observed in 13-week toxicology evaluations in rats and non-human primates (NHPs).

In November 2022, we announced that we voluntarily paused enrollment in the single ascending dose, or SAD, portion of our Phase 1 clinical trial evaluating SZN-1326 in healthy volunteers following the observation of treatment-related adverse events. Several subjects experienced asymptomatic liver transaminase elevations including three subjects with grade 3 ALT and AST elevations. There were no corresponding increases in total bilirubin, nor any changes in liver function markers such as coagulation markers or albumin. No other clinically significant laboratory abnormalities were observed, and the transaminase elevations resolved spontaneously in all subjects.

18

No serious adverse events were observed during the study. We intend to further analyze available clinical data with the study investigator and conduct additional pre-clinical experiments to identify the potential mechanism of the transaminase elevations to determine next steps in the development program.

We initiated a Phase 1 clinical trial in the second quarter of 2022 for SZN-043, our candidate in development for severe alcoholic hepatitis, or AH. SZN-043, a hepatocyte-specific R-spondin mimetic bispecific fusion protein targeting ASGR1, is the first development candidate using Surrozen’s SWEETS™ technology which is designed to mimic the regenerative properties of the protein R-Spondin by enhancing Wnt signaling in a cell-targeted manner. In multiple preclinical animal models of liver injury and fibrosis, SZN-043 has been shown to selectively activate Wnt signaling in the liver, stimulate transient hepatocyte proliferation, improve liver function and reduce fibrosis with no treatment-related adverse effects observed in 4-week GLP toxicology evaluations in mice and NHPs. Surrozen is developing SZN-043 for severe liver diseases, initially focusing on severe alcoholic hepatitis.

In November 2022, we provided an update on the ongoing SAD portion of the SZN-043 trial in healthy volunteers. Grade 1 and 2 treatment-related asymptomatic liver transaminase elevations were present in several subjects dosed with SZN-043. There were no corresponding increases in total bilirubin or GGT nor any changes in liver function markers such as coagulation markers or albumin in these subjects. No other clinically significant laboratory abnormalities were observed and the transaminase increases for these subjects resolved spontaneously. No serious adverse events have been observed to date in the ongoing study. We will be re-evaluating the overall clinical development timeline for this program.

In the first quarter of 2022, we nominated SZN-413, a Fzd4 targeted bi-specific antibody, as a development candidate for the treatment of retinal vascular associated diseases. Fzd4 mediated Wnt signaling is known to play a critical role in retinal vascular integrity and function. Data generated in preclinical models of retinopathy demonstrated SZN-413 stimulated Wnt signaling and was able to induce normal retinal vessel regrowth while suppressing pathological vessel growth. We recently entered into a Collaboration and Licensing Agreement, or CLA, with Boehringer Ingelheim International GmbH, or BI, to research, develop and commercialize Fzd4 bi-specific antibodies designed using the Company’s SWAP™ technology, including SZN-413.

The chart below represents a summary of our wholly owned product candidates:

 

By leveraging our scientific capabilities and approach, we have identified more than 20 potential tissue types to explore. We are assessing the potential to drive tissue repair in diseases resulting in tissue injury to organs including the lung, lacrimal gland, cornea, pancreas and skin.

The chart below represents a summary of our wholly-owned research programs:

 

Since our inception in 2015, we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, business planning, raising capital, developing and optimizing our Wnt therapeutics platform, identifying potential product candidates, undertaking research and development activities, engaging in strategic transactions, establishing and enhancing our

19

intellectual property portfolio, and providing general and administrative support for these operations. We have incurred net losses since inception. During the three months ended September 30, 2022 and 2021, we incurred net losses of $13.4 million and $14.0 million. During the nine months ended September 30, 2022 and 2021, we incurred net losses of $35.2 million and $39.7 million. As of September 30, 2022, we had an accumulated deficit of $177.9 million and cash, cash equivalents and marketable securities of $78.4 million.

We expect to continue to incur losses for the foreseeable future and expect to incur increased expenses as we expand our pipeline and advance our product candidates through clinical development and regulatory submissions. Specifically, in the near term we expect to incur substantial expenses relating to our Phase 1 clinical trials, the development and validation of our manufacturing processes, and other research and development activities.

Impacts of the Conflict between Russia and Ukraine and the COVID-19 Pandemic

Russia invaded Ukraine in February 2022 and is still engaged in active armed conflict against the country. The global COVID-19 pandemic continues to evolve, and we will continue to monitor developments closely. To date, our financial condition and operations have not been significantly impacted by the conflict between Russia and Ukraine and the COVID-19 pandemic. The extent of the impact on our business, operations and clinical development timelines and plans remains uncertain and will depend on certain developments, including the actions of U.S. and foreign governments to impose sanctions on Russia and to slow the spread of the COVID-19 and their impact on our preclinical development activities, regulatory agencies, clinical research organizations, or CROs, third-party manufacturers, other third parties with whom we do business, and, if we obtain regulatory approval to commence dosing in humans, trial enrollment and trial sites. We will continue to actively monitor the rapidly evolving situation and may take actions that alter our operations, including those that may be required by federal, state or local authorities or that we determine are in the best interests of our employees and other third parties with whom we do business.

Impact of Inflation

Inflation has increased and is expected to continue to increase for the near future. Inflation generally affects us by increasing our labor costs, research and clinical trial costs. While we do not believe that inflation has had a material effect on our financial condition and results of operations during the periods presented, it may result in increased costs in the foreseeable future and adversely affect our business and financial condition. In addition, inflation may cause us to experience greater uncertainty in general economic conditions and additional volatility in the market price of our common stock, which are already subject to the effects of rising interest rates and the ongoing military conflict in Ukraine. If these conditions worsen or do not improve, our ability to raise capital and our shareholders ability to sell their shares will be adversely affected.

Intellectual Property and Licensing Arrangements

As of September 30, 2022, our patent portfolio consisted of over 20 pending patent application families, including 15 families that have entered national phase in the United States and other countries, two families with pending Patent Cooperation Treaty, or PCT, applications, which have also been filed in certain non-PCT countries (e.g., Taiwan), and five families with pending U.S. provisional applications. These patent applications are directed to, for example, the SWAP™ and SWEETS™ platforms, the parental constructs of our two lead product candidate molecules, SZN-043 and SZN-1326, the recently out-licensed SZN-413, as well as methods of treating disorders of the liver, intestine, retina, cornea, lacrimal gland, and kidney.

We also have entered into patent and research tool license arrangements with third-parties, as described in Note 6 of the footnotes to the financial statements of this Report. The license agreements require milestone payments upon the achievement of certain regulatory and developmental stages. In addition, we will be required to pay royalties on sales of certain licensed products. As of September 30, 2022, we have incurred nominal fees and milestone payments under our license agreements. Upon the achievement of further regulatory and developmental milestones and the sale of licensed products, we may incur significant fees and royalties under these licenses.

As described in Note 11 of the footnotes to the financial statements of this Report, we executed the CLA with BI in October 2022 to research, develop and commercialize Fzd4 bi-specific antibodies designed using the Company’s SWAP™ technology, including SZN-413. We and BI will conduct partnership research focused on SZN-413 during a one-year period, which BI has the right to extend by up to six months. After completion of the partnership research, BI will have an exclusive, royalty-bearing, worldwide, sublicensable license, under our applicable patents and know-how, to develop, manufacture and commercialize such antibodies and their derivatives for all uses, and BI shall be responsible for all further research, preclinical and clinical development, manufacturing, regulatory approvals, and commercialization of licensed products at its expense.

Components of Results of Operations

Revenue

We had not generated any revenue through September 30, 2022 and prior to the execution of the CLA in October 2022. Under the CLA, we are eligible to receive a non-refundable upfront payment of $12.5 million as described in Note 11 of the footnotes to the financial statements of this Report. We do not expect to generate any revenue from the sale of our products unless and until we obtain regulatory clearance or approval.

Operating Expenses

We classify operating expenses into two main categories: (i) research and development expenses and (ii) general and administrative expenses.

Research and Development Expenses

Since our inception, we have focused significant resources on our research and development activities. Our research and development expenses consist of external and internal expenses incurred in connection with our research activities and development programs.

External expenses include:

•costs incurred under agreements with third parties, including CROs and other third parties conducting research and development activities on our behalf;

•costs of outside consultants, including their fees, stock-based compensation and related travel expenses;

•costs of laboratory supplies and acquiring, developing and manufacturing drug candidate materials; and

•license payments under our license agreements made for intellectual property used in research and development activities.

Internal expenses include:

•personnel-related costs, including salaries, bonuses, benefits and stock-based compensation for individuals involved in our research and product development activities; and

•facilities, depreciation, and other allocated costs, which include rent and insurance.

We track external expenses that are directly attributable to our clinical development candidates. We allocate internal expenses to our clinical development candidates on a program-specific basis. The internal expenses for early-stage research and discovery programs are not allocated as our internal resources, employees and infrastructure are typically deployed across multiple programs. As such, we do not provide financial information regarding the costs incurred for early-stage research and discovery programs on a program-specific basis.

We expect our research and development expenses will increase significantly for the foreseeable future as we identify and develop product candidates, in particular as we seek to continue clinical trials and pursue regulatory approval and commercialization for SZN-1326 and SZN-043.

The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of SZN-1326, SZN-043 and SZN-413 or any future product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates, many of which are outside of our control, including those associated with:

•our ability, and the ability of our primary business partners, to hire and retain key personnel;

•the timing and progress of preclinical and clinical development activities;

•the number and scope of preclinical and clinical programs we decide to pursue;

•our ability to maintain our current research and development programs and to establish new ones;

•establishing an appropriate safety profile with IND-enabling studies;

•the number of sites and patients included in the clinical trials;

•the countries in which the clinical trials are conducted;

•per patient trial costs;

21

•successful patient enrollment in, and the initiation of, clinical trials, as well as drop out or discontinuation rates, particularly in light of the lingering effects of the COVID-19 pandemic, the availability of alternate treatments and the limited pool of eligible patients in certain disease areas;

•the successful completion of clinical trials with safety, tolerability and efficacy profiles that are satisfactory to the FDA or any comparable foreign regulatory authority;

•the number of trials required for regulatory approval;

•the timing, receipt and terms of any regulatory approvals from applicable regulatory authorities;

•our ability to establish new licensing or collaboration arrangements;

•the performance of our current and future business partners, if any;

•establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

•significant and changing government regulation and regulatory guidance;

•the impact of any business interruptions to our operations or to those of the third parties with whom we work, particularly in light of the conflict between Russia and Ukraine and the current COVID-19 pandemic environment;

•the impact of inflation on our expenses;

•launching commercial sales of our drug candidates, if approved, whether alone or in collaboration with others;

•the effect of products that may compete with our product candidates or other market developments; and

•maintaining a continued acceptable safety profile of the drug candidates following approval.

Any changes in the outcome of any of these variables could mean a significant change in the costs and timing associated with the development of our drug candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel-related costs, including salaries, bonuses, benefits and stock-based compensation expense for personnel in executive, finance, human resources, business and corporate development, legal, information technology and other administrative functions. General and administrative expenses also include legal fees, professional fees paid for accounting, auditing, consulting, tax and investor relations services, insurance costs, and facility costs not otherwise included in research and development expenses, and costs associated with compliance with the rules and regulations of the SEC and Nasdaq. We expect that our general and administrative expenses will increase significantly for the foreseeable future to support our expanding headcount and operations.

Interest Income

Interest income consists primarily of interest earned on our cash equivalents and marketable securities.

Other Income (Expense), Net

Other income (expense), net consists of the gain on the change in fair value of warrant liabilities and expenses pertaining to the commitment shares issued to Lincoln Park Capital Fund, LLC, or Lincoln Park, under the Equity Purchase Agreement.

Total research and    development expenses	$	8,624	$	10,418	$	(1,794	)		-17	%

The decrease of $1.7 million, or 38%, in SZN-1326 program expenses for the three months ended September 30, 2022, compared to the three months ended September 30, 2021, is primarily due to the completion of manufacturing drug substance. The increase of $1.5 million, or 75%, in SZN-043 program expenses for the three months ended September 30, 2022, compared to the three months ended September 30, 2021, is primarily due to a $0.6 million increase in the allocated personnel costs and stock-based compensation expense and a $0.9 million decrease in the government grant from the National Institute of Health awarded in September 2020. There was a decrease of $1.6 million, or 42%, in discovery and preclinical stage program expenses for the three months ended September 30, 2022, compared to the three months ended September 30, 2021, as we shifted our resources to support our clinical programs.

General and Administrative Expenses

The increase of $1.7 million, or 52%, in general and administrative expenses for the three months ended September 30, 2022, compared to the three months ended September 30, 2021, is primarily attributable to a $1.0 million increase in personnel-related expenses due to an increase in headcount, a $0.3 million increase in professional fees and a $0.3 million increase in other expenses such as software licenses and computer supplies primarily due to the growth of operations and a $0.1 million increase in corporate insurance.

Interest Income

The increase of $0.2 million in interest income for the three months ended September 30, 2022, compared to the three months ended September 30, 2021, is primarily due to an increase in interest rates on our investments in money market funds and marketable securities.

Other Income (Expense), Net

The increase of $0.4 million, or 115%, in other income (expense), net, for the three months ended September 30, 2022, compared to the three months ended September 30, 2021, is primarily attributable to the transaction costs incurred during the three months ended September 30, 2021 related to the warrant liabilities issued in connection with the business combination consummated in August 2021. No such costs were incurred during the three months ended September 30, 2022.

Total research and    development expenses	$	27,576	$	29,284	$	(1,708	)		-6	%

The decrease of $3.7 million, or 32%, in SZN-1326 program expenses for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, is primarily due to the completion of manufacturing drug substance. The increase of $2.0 million, or 27%, in SZN-043 program expenses for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, is primarily due to the higher personnel costs and stock-based compensation expense allocated to the program. The preclinical, discovery and other research and development costs for the nine months ended September 30, 2022 is close to those for the nine months ended September 30, 2021.

General and Administrative Expenses

The increase of $4.5 million, or 44%, in general and administrative expenses for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, is primarily attributable to a $3.1 million increase in personnel-related expenses due to an increase in headcount and options granted to our employees, a $1.2 million increase in corporate insurance, a $0.4 million increase in other expenses such as software licenses and computer supplies primarily due to the growth of operations and a $0.2 million increase in recruiting costs, offset by a $0.4 million decrease in professional and consulting service fees related to the potential initial public offering prior to our decision to commence the business combination with Consonance-HFW Acquisition Corp.

Interest Income

The increase of $0.2 million, or 923%, in interest income for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, is primarily due to an increase in investments in money market funds and marketable securities and an increase in interest rates on our investments in money market funds and marketable securities.

Other Income (Expense), Net

The increase of $7.0 million in other income (expense), net, for the nine months ended September 30, 2022, compared to the nine months ended September 30, 2021, is primarily attributable to a $6.9 million increase in gain on the change in fair value of warrant liabilities and a $0.4 million decrease in expenses related to the warrant liabilities issued in connection with the business combination consummated in August 2021, offset by a $0.3 million increase in expenses related to the commitment shares issued to Lincoln Park under the Equity Purchase Agreement in February 2022.

Liquidity and Capital Resources

Since inception, we have incurred significant net operating losses and negative cash flows from operations. Historically, we financed our operations primarily from the sales of our redeemable convertible preferred stock. As of September 30, 2022, we had cash, cash equivalents and marketable securities of $78.4 million and an accumulated deficit of $177.9 million.

We entered into a purchase agreement and a registration rights agreement with Lincoln Park in February 2022, pursuant to which Lincoln Park is obligated to purchase up to $50.0 million of our common stock from time to time at our sole discretion over a 36-month period commencing on April 27, 2022. To date we have not sold any shares of common stock under the purchase agreement.

We executed the CLA in October 2022 and will receive a non-refundable upfront payment of $12.5 million under the CLA. $10.5 million of the upfront payment is expected to be received in the fourth quarter of 2022 and the remaining $2.0 million is expected to be received during the first six months of 2023. In addition, we will be eligible to receive success-based milestone payments up to $587 million plus mid-single digit to low-double digit royalties on net sales of the licensed products.

We believe, based on our current operating plan, that our existing cash, cash equivalents, and marketable securities, plus the gross cash proceeds of $12.5 million that will be received pertaining to the CLA, before deducting the fees of $1.3 million to be paid to Stanford and The Regents of the University of California, will be sufficient to fund our operations for at least the next 12 months from the date of this Report. However, if the anticipated operating results are not achieved in future periods, we could use our capital resources sooner than expected which may result in the need to reduce future planned expenditures and/or raise additional capital to continue to fund the operations.

24

Future Funding Requirements

To date, we have only generated revenue from our partnership with BI in connection with the CLA executed in October 2022. We have not generated and do not expect to generate any revenue from sale of our products unless and until we obtain regulatory approval and commercialize one of our product candidates, and we do not know when, or if, that will occur. We will continue to require substantial additional capital to develop our products candidates and fund operations for the foreseeable future. Since our inception in 2015, we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, business planning, raising capital, developing and optimizing our Wnt therapeutics platform, identifying potential product candidates, undertaking research and development activities, engaging in strategic transactions, establishing and enhancing our intellectual property portfolio, and providing general and administrative support for these operations. We expect our expenses to continue to increase in connection with our ongoing activities as we continue to advance our product candidates through clinical development and regulatory approval. In addition, we will continue to incur additional costs associated with operating as a public company.

We expect that our cash, cash equivalents and marketable securities, will provide the capital needed to fund our operations in the short-term. We expect that in the long-term we will need to raise additional capital through public or private equity offerings, debt financings or other capital sources, including government grants, potential collaborations with other companies or other strategic transactions as we do not expect sales of common stock to Lincoln Park and revenue derived from the CLA to be sufficient to provide all necessary financing until we are able to generate revenue on our own. There can be no assurance that sufficient funds will be available to us at all or on attractive terms when needed from these sources. If we are unable to obtain additional funding from these or other sources when needed, it may be necessary to significantly reduce expenses through reductions in staff and delaying, scaling back operations, or stopping certain research and development programs.

We have based our projections of operating capital requirements on assumptions that may prove to be incorrect and we may use all our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

•the scope, rate of progress, results and costs of researching and developing our lead product candidates or any future product candidates, conducting preclinical and clinical studies, in particular our current ongoing clinical studies of SZN-1326 and SZN-043;

•the outcome, costs, and timing involved in obtaining regulatory approvals for our lead product candidates or our other product candidates;

•the number and scope of clinical programs we decide to pursue;

•the cost of acquiring, licensing, or investing in product candidates and technologies;

•the costs associated with securing and establishing commercialization;

•our ability to maintain, expand, and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense, and enforcement of any patents or other intellectual property rights;

•our need and ability to retain key management and hire scientific, technical, business, and medical personnel;

•the effect of competing products and product candidates and other market developments;

•the timing, receipt, and amount of sales from SZN-1326, SZN-043 and any other product candidates, if approved;

•our need to implement additional internal systems and infrastructure, including financial and reporting systems;

•the economic and other terms, timing of, and success of any collaboration, licensing, or other arrangements which we may enter in the future; and

•the effects of the disruptions to and volatility in the credit and financial markets in the U.S. and worldwide from the conflict between Russia and Ukraine and the COVID-19 pandemic.

In addition, any future financing through sales of equity securities, including sales of common stock to Lincoln Park, will cause our stockholders to experience dilution. If we raise additional capital through debt financing, we may be subject to covenants that restrict our operations including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments, and engage in certain merger, consolidation, or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we are unable to raise additional funds when needed, we may be required to delay, reduce, or terminate some or all of our development programs and clinical trials. We may also be required to sell or license to others our rights to any of our current or future product candidates or discovery programs in certain territories or indications that we would prefer to develop and commercialize ourselves.

Summary of Cash Flows

The following table sets forth the primary sources and uses of cash, cash equivalents and restricted cash for the periods presented below (in thousands):

	Nine Months Ended September 30,
	2022			2021
Net cash used in operating activities	$	(43,940	)	$	(37,270	)
Net cash provided by (used in) investing activities		36,396			(61,087	)
Net cash (used in) provided by financing activities		(16	)		124,471
Net (decrease) increase in cash, cash equivalents and restricted cash	$	(7,560	)	$	26,114

Cash Used in Operating Activities

Cash used in operating activities of $43.9 million for the nine months ended September 30, 2022 was primarily due to the use of funds in our operations and the resulting net loss of $35.2 million, a net change of $7.8 million in our net operating assets and liabilities and $1.0 million in non-cash charges. The net change in our operating assets and liabilities was primarily due to the cash used in prepaid expenses, accounts payable and accrued liabilities. Cash used in operating activities of $37.3 million for the nine months ended September 30, 2021 was primarily due to the use of funds in our operations and the resulting net loss of $39.7 million and a net change of $2.0 million in our net operating assets and liabilities, partially offset by $4.4 million in non-cash charges. The net change in our operating assets and liabilities was primarily due to a net increase in prepaid expenses, accounts payable and accrued liabilities.

Cash Provided by (Used in) Investing Activities

Cash provided by investing activities of $36.4 million for the nine months ended September 30, 2022 was primarily related to the $57.9 million of proceeds from maturities of marketable securities, offset by $0.6 million of cash used for the purchase of laboratory and computer equipment and $20.9 million of cash used for the purchase of marketable securities. Cash used in investing activities of $61.1 million for the nine months ended September 30, 2021 consisted primarily of $74.3 million of cash used for the purchase of marketable securities and $0.9 million of cash used for the purchase of laboratory equipment, partially offset by $14.2 million of proceeds from sales and maturities of marketable securities.

Cash (Used in) Provided by Financing Activities

Cash used in financing activities of $16,000 for the nine months ended September 30, 2022 was related to the repurchase of early exercised options. Cash provided by financing activities of $124.5 million for the nine months ended September 30, 2021 consisted primarily of $124.1 million of net proceeds from the business combination consummated in August 2021 and $0.4 million of proceeds from the exercise of options.

Contractual Obligations and Commitments

Our contractual obligations as of September 30, 2022 have not materially changed from what we presented in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2021.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates.

During the nine months ended September 30, 2022, there were no material changes to our critical accounting policies or in the methodology used for estimates from those described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2021.

Emerging Growth Company Status

We are an emerging growth company, or EGC, as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. The JOBS Act permits companies with EGC status to take advantage of an extended transition period to comply with new or revised accounting standards, delaying the adoption of these accounting standards until they would apply to private companies. We have elected

26

to use this extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date the Company (i) is no longer an EGC or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our unaudited condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting standards as of public company effective dates.

In addition, we intend to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an EGC, we intend to rely on such exemptions, we are not required to, among other things: (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act; (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board; and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation.

We will remain an EGC under the JOBS Act until the earliest of (i) the last day of the fiscal year (a) of 2025, (b) the year in which we have total annual gross revenue of at least $1.235 billion, or (c) the year in which we are deemed to be a large accelerated filer; or (ii) the date on which we have issued more than $1 billion in non-convertible debt securities during the prior three-year period.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and are not required to provide the information otherwise required under this item.

Item 4. Controls and Procedures.

Management’s Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f). Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report. Based on the evaluation of our disclosure controls and procedures as required by Rule 13a-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Report, our disclosure controls and procedures were not effective at the reasonable assurance level as a result of the material weakness described below.

Material Weakness

As previously reported, in connection with the audit of our financial statements for the year ended December 31, 2020, we and our independent registered public accounting firm identified one material weakness in our internal control over financial reporting. This material weakness continued to exist as of September 30, 2022. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness that we identified relates to a lack of sufficient accounting and financial reporting personnel with requisite knowledge and experience in application of GAAP and SEC rules.

To respond to the material weakness, we have devoted, and plan to continue to devote, significant effort and resources to the remediation and improvement of our internal control over financial reporting. We are in the process of implementing measures designed to improve our internal control over financial reporting and remediate the control deficiencies that led to the material weakness, including hiring additional accounting personnel, obtaining advisory services from professional consultants with GAAP and SEC reporting experience in their industry, research materials and documents and increased communication among our personnel and third-party professionals with whom we consult regarding complex accounting applications and expanding the capabilities of the existing accounting and financial personnel through continuous training and education in the accounting and reporting requirements under GAAP and the SEC rules and regulations. The process of designing and implementing effective internal controls is a continuous effort that requires us to anticipate and react to changes in our business and the economic and regulatory environments and to expend significant resources to maintain a system of internal controls that is adequate to satisfy our reporting obligations as a public company.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the

27

disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

28

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be subject to legal proceedings. We are not currently a party to or aware of any proceedings that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

Item 1A. Risk Factors.

Except as discussed below, there have been no material changes from the risk factors previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 28, 2022, under the heading “Item 1A. Risk Factors”, which are incorporated by reference herein to the extent they are not modified or updated below. Investing in our securities involves a high degree of risk. Before you make an investment decision with respect to our securities, in addition to the risks and uncertainties discussed above under “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider the risks and uncertainties described below and in our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on March 28, 2022, under the heading “Item 1A. Risk Factors.” These risks should be considered along with all of the other information contained in this Report, including our consolidated financial statements and related notes, before deciding to invest in our securities. If any of the events or developments described in our risk factors were to occur, our business, prospects, operating results and financial condition could suffer materially, the trading price of our securities could decline and you could lose all or part of your investment. The risks and uncertainties described below and in our Annual Report are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

The following risk factors supplement the risk factors included in the Annual Report.

Summary of Risk Factors

Below is a summary of the material factors that make an investment in our common stock speculative or risky. This summary does not address all of the risks that we face. Our business involves significant risks that may have a material adverse effect on our business, financial condition, results of operations, prospects and stock price. These risks are more fully described below and include, among others:

•We are an early stage biopharmaceutical company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could result in a decline in the market value of our common stock.

•Phase 1 clinical trials for SZN-1326 have been voluntarily paused following the observation of treatment-related adverse events. We will further analyze available clinical data and conduct additional pre-clinical experiments to understand and potentially resolve these observations; however, this additional work will cause delays in our development plans and require additional capital to resume and complete our clinical trials and development efforts with respect to SZN-1326. Clinical development of SZN-1326 may be further delayed or abandoned, and adversely affect our financial condition and results of operations.

•Phase 1 clinical trials for SZN-043 in healthy volunteers are ongoing but treatment-related adverse events have been observed, and if these findings continue or worsen, we could experience delays in our development plans for SZN-043 and require additional capital to complete our clinical trials and development efforts for SZN-043.

•None of our products have received regulatory approval; our ability to achieve and sustain profitability depends on obtaining regulatory approval and successfully commercializing product candidates, either alone or with collaborators.

•If any current or future product candidate, after it begins clinical trials or receives marketing approval, demonstrates undesirable side effects caused by the product candidate, our ability to market and derive revenue from the product candidate could be compromised.

•We will need substantial additional funds to advance development of product candidates and our Wnt therapeutics platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates.

•We rely on third parties to conduct our preclinical studies and plan to rely on third parties to conduct clinical trials, and those third parties may not perform satisfactorily.

•If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

29

•The manufacturing of our product candidates is complex. We and our third-party manufacturers may encounter difficulties in production. If we encounter any such difficulties, our ability to supply our product candidates for clinical trials or, if approved, for commercial sale, could be delayed or halted entirely.

•We face competition from entities that have developed or may develop product candidates for the treatment of the diseases that we may target, including companies developing novel treatments and therapeutic platforms. If these companies develop therapeutics or product candidates more rapidly than we do, or if their therapeutics or product candidates are more effective or have fewer side effects, our ability to develop and successfully commercialize product candidates may be adversely affected.

•We have identified a material weakness in our internal control over financial reporting. If our remediation of the material weakness is not effective, or if we experience additional material weaknesses in the future or otherwise fails to maintain an effective system of internal controls in the future, we may not be able to accurately report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

•Our future growth may depend, in part, on our ability to operate in foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.

•Our business, operations and clinical development plans and timelines could be adversely affected by the effects of the conflict between Russia and Ukraine, health epidemics, including the ongoing COVID-19 pandemic, natural disasters and other events on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom it conducts business, including contract manufacturers, CROs, shippers and others.

•If we are unable to obtain or protect intellectual property rights related to our technology and current or future product candidates, or if our intellectual property rights are inadequate, we may not be able to compete effectively.

•Some intellectual property that we have in-licensed may have been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights and limit our ability to contract with non-U.S. manufacturers.

•Clinical development includes a lengthy and expensive process with an uncertain outcome, we may have negative results and results of earlier studies and trials may not be predictive of future trial results.

•We have conducted certain of our clinical trials for our product candidates outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case its development plans will be delayed, which could materially harm its business.

•A few stockholders, including one of our directors, may control the voting rights with respect to a large number of shares of our common stock. They could exercise their voting power in a manner that adversely affects the Company or our stockholders.

•A few stockholders, including one of our directors, may control the voting rights with respect to a large number of shares of our common stock. They could exercise their voting power in a manner that adversely affects the Company or our stockholders.

Risks Related to Our Business

We are a clinical stage biopharmaceutical company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could result in a decline in the market value of our common stock.

We are a clinical stage biopharmaceutical company with a history of losses. Since its inception, we have devoted substantially all of its resources to research and development, preclinical studies, clinical trials, building our management team and building our intellectual property portfolio, and have incurred significant operating losses. Substantially all of our losses have resulted from expenses incurred in connection with its research and development programs and from general and administrative costs associated with our operations. To date, we have not generated any revenue from product sales, and have not sought or obtained regulatory approval for any product candidate. Furthermore, we do not expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies and clinical trials and the regulatory approval process for our current and potential future product candidates.

We expect our net losses to increase substantially as our lead product candidates, SZN-1326, SZN-043 and SZN-413, advance through clinical development. However, the amount of our future losses is uncertain. Our ability to achieve or sustain profitability, if ever, will depend on, among other things, successfully developing product candidates, resuming clinical trials for SZN-1326, continuing clinical trials for SZN-043, successful development and testing of SZN-413 through our partnership with Boehringer Ingelheim International

30

GmbH, or BI, obtaining regulatory approvals to market and commercialize product candidates, manufacturing any approved products on commercially reasonable terms, entering into potential future alliances, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we, or our current and potential future collaborators, are unable to commercialize one or more of our product candidates, or if sales revenue from any product candidate that receives approval is insufficient, we will not achieve or sustain profitability, which could have a material and adverse effect on our business, financial condition, results of operations and prospects.

Phase 1 clinical trials for SZN-1326 in healthy volunteers have been voluntarily paused due to the observation of treatment-related adverse events, causing delays in our development plans and requiring additional capital, and we do not know when, or if, we will be able to resume and complete our clinical trials and development efforts for SZN-1326.

Clinical trials for SZN-1326 have been voluntarily paused following the observation of treatment-related adverse events. Several subjects experienced asymptomatic transaminase elevations including three subjects with Grade 3 ALT and AST elevations. The transaminase elevations resolved spontaneously in all subjects, and no serious adverse events were observed during the study. We intend to further analyze available clinical data and conduct additional pre-clinical experiments to understand and potentially resolve these observations; however, this additional work will cause delays in our development plans and require additional capital to resume and complete our development efforts and clinical trials for SZN-1326. If we are unable to identify the cause of these findings and develop a solution in a timely manner, or at all, development of SZN-1326 may be further delayed or fail in clinical development and adversely affect our financial condition and results of operations.

Phase 1 clinical trials for SZN-043 in healthy volunteers are ongoing but treatment-related adverse events have been observed, and if these findings continue or worsen, we may experience delays in our development plans for SZN-043 and require additional capital to complete our clinical trials and development efforts for SZN-043.

Clinical trials for SZN-043 are ongoing, but Grade 1 and 2 treatment-related asymptomatic transaminase elevations were present in several subjects dosed with SZN-043. The transaminase elevations for these subjects resolved spontaneously, and no serious adverse events were observed during the study. We intend to further analyze available clinical data and modify clinical studies as necessary to understand and safely resolve these observations. If these observations continue or worsen, we may need to pause the trials to perform additional pre-clinical experiments, causing delays in our development plans and requiring additional capital to resume and complete our development efforts and clinical trials for SZN-043. If we are unable to safely continue the trials for SZN-043 and resolve these observations, development of SZN-043 may be substantially delayed or abandoned and adversely affect our financial condition and results of operations.

We have no products on the market or that have gained regulatory approval. Only two of our product candidates have just begun clinical trials in humans; our ability to achieve and sustain profitability will depend on obtaining regulatory approvals for and successfully commercializing product candidates, either alone or with collaborators.

Before obtaining regulatory approval for the commercial distribution of our product candidates, we or a collaborator must conduct extensive preclinical studies, followed by clinical trials to demonstrate the safety, purity and potency, or efficacy of our product candidates in humans. There is no guarantee that the U.S. Food and Drug Administration, or the FDA, or other regulatory authorities will permit us to conduct clinical trials. Further, we cannot be certain of the timely completion or outcome of our preclinical studies and cannot predict if the FDA or other regulatory authorities will accept our proposed clinical programs, our clinical protocols or if the outcome of our preclinical studies will ultimately support the further development of our preclinical programs or testing in humans. As a result, we cannot be sure that we will be able to submit Investigational New Drugs, or INDs, or similar applications for our proposed clinical programs on the timeline we expect, if at all, and cannot be sure that submission of INDs or similar applications will result in the FDA or other regulatory authorities allowing clinical trials for any of our product candidates to begin.

SZN-043 is in clinical development and clinical trials for SZN-1326 are paused as discussed above. We are subject to the risks of failure inherent in the development of product candidates based on novel approaches, targets and mechanisms of action. Although we are working to resume the Phase 1 clinical trial of SZN-1326 in healthy volunteers and continue the Phase 1 clinical trial of SZN-043 in healthy volunteers and in patients with impaired liver function, there is no guarantee that we will be able to proceed with clinical development of either of these product candidates or that either product candidate will demonstrate a clinical benefit once we further advance these candidates. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties that we have encountered and that are frequently encountered by clinical stage biopharmaceutical companies such as us.

We may not be able to access the financial resources to resume or continue development of, or to enter into any collaborations for, SZN-1326, SZN-043 or any potential future product candidates. This may be exacerbated if we experience any issues that delay or prevent regulatory approval of, or our ability to commercialize, a product candidate, such as:

•negative or inconclusive results from our preclinical or clinical trials (including as discussed above) or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;

31

•product-related side effects experienced by participants in our clinical trials (such as the asymptomatic transaminase elevations discussed above) or by individuals using drugs or therapeutic antibodies similar to ours, including immunogenicity;

•delays in submitting IND applications or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;

•conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;

•delays in enrolling research subjects in clinical trials;

•high drop-out rates of research subjects;

•inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

•chemistry, manufacturing and control, or CMC, challenges associated with manufacturing and scaling up biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;

•greater-than-anticipated clinical trial costs;

•poor potency or effectiveness of our product candidates during clinical trials;

•unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;

•delays as a result of the COVID-19 pandemic or events associated with the pandemic;

•failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;

•delays and changes in regulatory requirements, policies and guidelines; or

•the FDA or other regulatory authorities interpreting our data differently than it does.

Further, we and any potential future collaborator may never receive approval to market and commercialize any product candidate. Even if we or a potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as were intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or a potential future collaborator may be subject to post-marketing testing requirements to maintain regulatory approval.

SZN-1326, SZN-043, SZN-413 and any future product candidate that is tested in humans may not demonstrate the safety, purity and potency, or efficacy, necessary to become approvable or commercially viable.

We may ultimately discover that SZN-1326, SZN-043 and SZN-413 do not possess certain properties that we believe are helpful for therapeutic effectiveness and safety. For example, although SZN-043 and SZN-1326 exhibited encouraging results in animal studies, including improvement of liver function in multiple animal models of liver injury, it may not demonstrate the same properties in humans and may interact with human biological systems in unforeseen, ineffective or harmful ways, as shown by the observations of asymptomatic transaminase elevations discussed above. As a result, we may never succeed in developing a marketable product based on any of our current or future product candidates. If SZN-1326, SZN-043, SZN-413 or any of our potential future product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could require us to change our focus and approach to antibody-based discovery and development and materially and adversely affect our business, financial condition, results of operations and prospects.

We may not be successful in our efforts to use and expand our Wnt therapeutics platform to build a pipeline of product candidates.

A key element of our strategy is to use and expand our Wnt therapeutics platform to discover and develop a portfolio of Wnt product candidates that can facilitate the repair and/or regeneration of damaged tissue for patients suffering from a variety of severe diseases. Although our research and development efforts to date have resulted in the discovery and development of SZN-1326, SZN-043, SZN-413 and other potential product candidates, our current product candidates may not be safe or effective therapeutics and we may not be able to develop any successful product candidates. Our platform is evolving and may not reach a state at which building a pipeline of product candidates is possible. Even if we are successful in building its pipeline of product candidates, the potential product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable toxicity or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. Observations of asymptomatic transaminase elevations in clinical trials of SZN-1326 and SZN-043, as announced in November 2022, could also impair our ability to build and expand our Wnt platform if we are unable to successfully resolve those observations. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future.

32

If SZN-1326, SZN-043, SZN-413 or any potential future product candidate causes undesirable side effects after it begins clinical trials or receives marketing approval, our ability to market and derive revenue from the product candidate could be compromised.

Undesirable side effects caused by SZN-1326, SZN-043, SZN-413 or any potential future product candidate could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. While we have initiated clinical trials for SZN-1326 and SZN-043, we have already experienced findings that have caused us to voluntarily pause clinical trials for SZN-1326 and make adjustments to clinical trials for SZN-043. It is also likely that there will be side effects associated with the testing or use of our product candidates. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of these side effects. In such an event, our trials could be suspended (as we have done for SZN-1326) or terminated and the FDA or other regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. Such side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. For example, certain researchers have noted that therapeutics targeting the Wnt pathway may lead to tumor formation or proliferation as a result of the downstream impacts of Wnt signaling. To date, we have not observed any such tumor formation with SZN-1326 or SZN-043 in our preclinical toxicology studies and clinical trials, but there can be no guarantee that our current or future product candidates will not result in tumor formation. Any of these occurrences or failure to resolve the findings related to SZN-1326 and SZN-043 may materially and adversely affect our business and financial condition and impair our ability to generate revenues.

Further, clinical trials by their nature use a sample of the potential patient population. With a limited number of patients and limited duration of exposure, rare and severe side effects of a product candidate may only be uncovered when a significantly larger number of patients are exposed to the product candidate or when patients are exposed for a longer period of time.

In the event that any of our current or potential future product candidates receive regulatory approval and we or others identify undesirable side effects caused by one of these products, any of the following adverse events could occur, which could result in the loss of significant revenue to us and materially and adversely affect our results of operations and business:

•regulatory authorities may withdraw their approval of the product or seize the product;

•we may be required to recall the product or change the way the product is administered to patients;

•additional restrictions may be imposed on the marketing of the particular product or the manufacturing processes for the product or any component thereof;

•we may be subject to fines, injunctions or the imposition of civil or criminal penalties;

•regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;

•regulatory authorities may require additional post-marketing safety studies or registries;

•we may be required to create a Medication Guide outlining the risks of such side effects for distribution to patients;

•we could be sued and held liable for harm caused to patients;

•the product may become less competitive; and

•our reputation may suffer.

We will need substantial additional funds to advance development of product candidates and our Wnt therapeutics platform, but sufficient funds may not be available when needed, or on terms favorable to us, due to various market conditions and factors, causing us to delay, limit or eliminate the development and commercialization of our product candidates.

The development of biopharmaceutical product candidates is capital-intensive. If SZN-1326, SZN-043, SZN-413 or potential future product candidates advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. We have used substantial funds to develop our Wnt therapeutics platform, SZN-1326, SZN-043 and other product candidates and we will require significant funds to continue to develop our platform, resume clinical trials for SZN-1326, continue clinical trials for SZN-043 and conduct further research and development, including preclinical studies and clinical trials.

To date, we have primarily financed our operations through the sale of equity securities. Until such time as we can generate sufficient revenue from sales of our product candidates, if ever, we expect to finance our operations through public or private equity offerings, debt financings or other capital sources, including government grants, potential collaborations with other companies or other strategic transactions. In February 2022, we entered into a purchase agreement and a registration rights agreement with Lincoln Park Capital Fund, LLC, or Lincoln Park, pursuant to which we have the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $50.0 million of our common stock from time to time over a 36-month period, subject to certain conditions and limitations. We may not be able to receive any or all of the funds from Lincoln Park because of the limitations, restrictions, requirements, events of default and other provisions contained in the purchase agreement that could limit our ability to cause Lincoln

33

Park to purchase our common stock. If our stock price drops, we also may not be able to sell shares to Lincoln Park at all or in amounts sufficient to obtain necessary financing.

We may be unable to raise additional funds or to enter into such agreements or arrangements on favorable terms, or at all. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the disruptions to, and volatility in, the credit and financial markets in the United States, and worldwide resulting from the COVID-19 pandemic and the conflict between Russia and Ukraine. The overall impact of these events on our business may be significantly affected by the actions of U.S. and foreign governments to slow the spread of COVID-19 and to impose sanctions on Russia. These events and actions could result in severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive.

If we are unable to raise additional capital in sufficient amounts, in a timely manner or on terms acceptable to us, we may have to significantly delay, scale back, or discontinue the development of our product pipeline or other research and development initiatives. We also could be required to seek collaborators for our product pipeline and any future product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available or relinquish or license on unfavorable terms our rights to our product pipeline and any future product candidates in markets where we otherwise would seek to pursue development or commercialization ourselves.

Our future capital requirements and the period for which we expect existing resources to support our operations may vary significantly from what we expect. For example, we are uncertain (i) when we will be able to resume clinical trials for SZN-1326, if at all, and (ii) as to the amount of resources we will need to devote to get clinical trials for SZN-1326 back on track. Our monthly spending levels vary based on new and ongoing research and development and other corporate activities. Because the length of time and activities associated with successful research and development of product candidates is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. The timing and amount of our operating expenditures will depend largely on:

•the timing and progress of preclinical and clinical development of SZN-1326, SZN-043, SZN-413 and other potential future product candidates;

•the timing and progress of the development of our Wnt therapeutics platform;

•the price and pricing structure that we are able to obtain from our third-party contract manufacturers to manufacture our preclinical study and clinical trial materials and supplies;

•the extent to which prices for supplies and materials increase due to inflationary pressures and labor market constraints;

•the number and scope of preclinical and clinical programs we decide to pursue;

•our ability to maintain our current licenses, research and development programs and to establish new collaborations;

•the progress of the development efforts of parties with whom we may in the future enter into collaboration and research and development agreements;

•the costs involved in obtaining, maintaining, enforcing and defending patents and other intellectual property rights;

•the impact of the COVID-19 pandemic on our business;

•the cost and timing of regulatory approvals; and

•our efforts to enhance operational systems and hire additional personnel, including personnel to support development of our product candidates and satisfy our obligations as a public company.

If we are unable to raise sufficient capital when needed, our business, financial condition and results of operations will be harmed, and we will need to significantly modify our operational plans. We may also have to liquidate assets, and the value we receive for any assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements.

We may expend our limited resources to pursue a particular product candidate and fail to capitalize on product candidates that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we intend to focus our efforts on specific research and development programs, including clinical development of SZN-1326, SZN-043 and SZN-413. As a result, we may forgo or delay pursuit of other opportunities, including with potential future product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial product candidates or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable product candidates. If we do not resume clinical trials for SZN-1326, we will not see a return on the capital spent to develop SZN-1326, resulting in adverse effects on our financial condition and ability to pursue other opportunities. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to

34

that product candidate through collaborations, licensing or other royalty arrangements in cases in which we would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available or as additional analyses are conducted, and as the data are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose interim, preliminary or topline data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular trial. We also make assumptions, estimations, calculations and conclusions as part of its analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, preliminary or topline results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. For example, in November 2022, we reported observations in connection with clinical studies on SZN-1326 and SZN-043, and these observations could differ materially from future findings. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should be viewed with caution until the final data are available. From time to time, we may also disclose interim, preliminary or topline data from our clinical studies. Interim, topline or preliminary data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Adverse differences between preliminary, topline or interim data and final data could significantly harm our business prospects.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and the value of us in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular product, product candidate or our business. If the topline data that we report differs from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition

We may not be able to enter into strategic transactions on acceptable terms, if at all, which could adversely affect our ability to develop and commercialize current and potential future product candidates, impact our cash position, increase our expense, and present significant distractions to our management.

From time to time, we consider strategic transactions, such as collaborations, acquisitions of companies, asset purchases, joint ventures and out- or in-licensing of product candidates or technologies. For example, around the beginning of October 2022, we entered into a strategic partnership with BI for the research and development of SZN-413 for the treatment of retinal diseases. We will continue to evaluate and, if strategically attractive, seek to enter into collaborations, including with biotechnology or biopharmaceutical companies or hospitals. The competition for collaborators is intense, and the negotiation process is time-consuming and complex. If we are not able to enter into strategic transactions, we may not have access to required liquidity or expertise to further develop our potential future product candidates or our Wnt therapeutics platform. Any such collaboration, or other strategic transaction, may require us to incur non-recurring or other charges, increase its near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business.

We also may acquire additional technologies and assets, form strategic alliances or create joint ventures with third parties that it believes will complement or augment our existing business, but we may not be able to realize the benefit of acquiring such assets. Conversely, any new collaboration that we enter into may be on terms that are not optimal for us or our product candidates. These transactions would entail numerous operational and financial risks, including:

•exposure to unknown liabilities;

•disruption of our business and diversion of its management’s time and attention in order to manage a collaboration or develop acquired products, product candidates or technologies;

•incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs;

•higher-than-expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses;

•difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business;

•impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership; and

35

•the inability to retain key employees of any acquired business.

Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any current or future partnerships and transactions may be subject to the foregoing or other risks and our business could be materially harmed by such transactions. Conversely, any failure to enter any collaboration or other strategic transaction that would be beneficial to us could delay the development and potential commercialization of our product candidates and have a negative impact on the competitiveness of any product candidate that reaches market.

In addition, to the extent that any current or future collaborators terminate a collaboration agreement, we may be forced to independently develop our current and future product candidates, including funding preclinical studies or clinical trials, assuming marketing and distribution costs and maintaining, enforcing and defending intellectual property rights, or, in certain instances, abandon product candidates altogether, any of which could result in a change to our business plan and materially harm its business, financial condition, results of operations and prospects.

We and our collaborators may not achieve projected discovery and development milestones and other anticipated key events in the time frames that such collaborators announce, which could have an adverse impact on our business and could cause our stock price to decline.

From time to time, we expect that we will make public statements regarding the expected timing of certain milestones and key events, such as the commencement and completion of preclinical and IND-enabling studies in our internal drug discovery programs as well as the commencement and completion of our planned clinical trials. The actual timing of these events can vary dramatically due to a number of factors such as delays or failures in our or any future collaborators’ drug discovery and development programs, the amount of time, effort and resources committed by us and any future collaborators, and the numerous uncertainties inherent in the development of drugs. As a result, there can be no assurance that we or any current or future collaborators’ programs will advance or be completed in the time frames we or they announce or expect. If we or any collaborators fail to achieve one or more of these milestones or other key events as planned, including the milestones in our agreement with BI, our business could be materially adversely affected and the price of Common Stock could decline.

Clinical trials are expensive, time-consuming and difficult to design and implement.

Human clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. Because our current and potential future product candidates are based on new technologies and discovery approaches, we expect that they will require extensive research and development and have substantial manufacturing and processing costs. In addition, because of the limited number of drug candidates that target the Wnt pathway, the FDA or other regulatory authorities may require us to perform additional testing before commencing or resuming clinical trials and be hesitant to allow us to enroll patients impacted with its targeted disease indications in Phase 1 trials. If we are unable to enroll patients impacted by the targeted disease indications in our current and planned Phase 1 trials, we may continue to be delayed or would be delayed in obtaining potential proof-of-concept data in humans, which could extend our development timelines. In addition, costs to treat patients and to treat potential side effects that may result from our product candidates may be significant. Accordingly, our clinical trial costs are likely to be high and could have a material and adverse effect on our business, financial condition, results of operations and prospects.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

We may not be able to initiate, resume or continue clinical trials for our current or potential future product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or other regulatory authorities. In particular, we are working to resume Phase 1 clinical trials for SZN-1326 in healthy volunteers, and continue SZN-043 through a Phase 1 clinical trial in healthy volunteers and in patients with impaired liver function. We cannot predict how difficult it will be to maintain enrollment of patients for trials in these populations. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons. The enrollment of patients depends on many factors, including:

•the severity of the disease under investigation;

•the patient eligibility criteria defined in the clinical trial protocol;

•the size of the patient population required for analysis of the trial’s primary endpoints;

•the proximity and availability of clinical trial sites for prospective patients;

•willingness of physicians to refer their patients to our clinical trials;

•our ability to recruit clinical trial investigators with the appropriate competencies and experience;

•clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating;

•our ability to obtain and maintain patient consents;

36

•the risk that patients enrolled in clinical trials will drop out of the trials before completion; and

•factors we cannot control that may limit patients, principal investigators or staff or clinical site available, including restrictions related to the COVID-19 pandemic and the conflict between Russia and Ukraine.

In addition, our future clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for their clinical trials at such clinical trial sites. Additionally, because some of our clinical trials will be in patients with advanced disease who may experience disease progression or adverse events independent from our product candidates, such patients may be unevaluable for purposes of the trial and, as a result, we may require additional enrollment. Delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates.

If we are unable to resume clinical trials for SZN-1326 or clinical trials for our product candidates are prolonged, delayed or stopped, we may be unable to seek or obtain regulatory approval and commercialize our product candidates on a timely basis, or at all, which would require us to incur additional costs and delay our receipt of any product revenue.

We have experienced, and may further experience, delays in our ongoing or future preclinical studies or clinical trials, and we do not know whether preclinical studies or clinical trials will begin on time, resume in a timely manner, need to be redesigned, enroll an adequate number of patients on time or be completed on schedule, if at all. The resumption of clinical trials for SZN-1326 and the commencement or completion of our clinical trials could be substantially delayed or prevented by many factors, including:

•further discussions with the FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials, including the endpoint measures required for regulatory approval and our statistical plan;

•the limited number of, and competition for, suitable study sites and investigators to conduct our clinical trials, many of which may already be engaged in other clinical trial programs with similar patients, including some that may be for the same indication as our product candidates;

•any delay or failure to obtain timely approval or agreement to commence a clinical trial in any of the countries where enrollment is planned;

•inability to obtain sufficient funds required for a clinical trial;

•clinical holds on, or other regulatory objections to, a new or ongoing clinical trial;

•delay or failure to manufacture sufficient quantities or inability to produce quantities of consistent quality, purity and potency of the product candidate for our clinical trials;

•delay or failure to reach agreement on acceptable clinical trial agreement terms or clinical trial protocols with prospective sites or CROs, the terms of which can be subject to extensive negotiation and may vary significantly among different sites or CROs;

•delay or failure to obtain institutional review board, or IRB, approval to conduct a clinical trial at a prospective site;

•the FDA or other comparable foreign regulatory authorities may require us to submit additional data or impose other requirements before permitting us to initiate a clinical trial;

•slower than expected rates of patient recruitment and enrollment;

•failure of patients to complete the clinical trial;

•the inability to enroll a sufficient number of patients in studies to ensure adequate statistical power to detect statistically significant treatment effects;

•unforeseen safety issues, including severe or unexpected drug-related adverse effects experienced by patients, including possible deaths;

•lack of efficacy or failure to measure a statistically significant clinical benefit within the dose range with an acceptable safety margin during clinical trials;

•termination of our clinical trials by one or more clinical trial sites;

•inability or unwillingness of patients or clinical investigators to follow our clinical trial protocols;

•inability to monitor patients adequately during or after treatment by us or our CROs;

37

•our CROs or clinical study sites failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, deviating from the protocol or dropping out of a study;

•inability to address any noncompliance with regulatory requirements or safety concerns that arise during the course of a clinical trial;

•the impact of, and delays related to, health epidemics such as the COVID-19 pandemic;

•the need to suspend, repeat or terminate clinical trials as a result of non-compliance with regulatory requirements, inconclusive or negative results or unforeseen complications in testing; and

•the suspension or termination of our clinical trials upon a breach or pursuant to the terms of any agreement with, or for any other reason by, any future strategic collaborator that have responsibility for the clinical development of any of our product candidates.

Changes in regulatory requirements, policies and guidelines may also occur and we may need to significantly modify our clinical development plans to reflect these changes with appropriate regulatory authorities. These changes may require us to renegotiate terms with CROs or resubmit clinical trial protocols to IRBs for re-examination, which may impact the costs, timing or successful completion of a clinical trial. Our clinical trials may be suspended or terminated at any time by them, the FDA, other regulatory authorities, the IRB overseeing the clinical trial at issue, any of our clinical trial sites with respect to that site, or us.

Any failure or significant delay in commencing or completing clinical trials for our product candidates, any failure to obtain positive results from clinical trials, any safety concerns related to our product candidates, or any requirement to conduct additional clinical trials or other testing of our product candidates beyond those that it currently contemplates would adversely affect our ability to obtain regulatory approval and our commercial prospects and ability to generate product revenue will be diminished.

If the market opportunities for our current and potential future product candidates, including SZN-1326, SZN-043 and SZN-413, are smaller than we believe they are, our future product revenues may be adversely affected and our business may suffer.

Our understanding of the number of people who suffer from certain types of moderate to severe IBD, severe AH and retinal vascular associated diseases that SZN-1326, SZN-043 and SZN-413, respectively, may be able to treat are based on estimates. These estimates may prove to be incorrect, and new studies may reduce the estimated incidence or prevalence of these diseases. The number of patients in the United States or elsewhere may turn out to be lower than expected, may not be otherwise amenable to treatment with our current or potential future product candidates or patients may become increasingly difficult to identify and access, all of which would adversely affect our business prospects and financial condition. In particular, the treatable population for our candidates may further be reduced if its estimates of addressable populations are erroneous or sub-populations of patients do not derive benefit from SZN-1326, SZN-043 or SZN-413.

Further, there are several factors that could contribute to making the actual number of patients who receive our current or potential future product candidates less than the potentially addressable market. These include the lack of widespread availability of, and limited reimbursement for, new therapies in many underdeveloped markets.

Our international operations may expose us to business, political, operational and financial risks associated with doing business outside of the United States.

Our business is subject to risks associated with conducting business internationally. Some of our suppliers are located outside of the United States and we have conducted, and anticipate conducting additional future, clinical trials, including our Phase 1 trials for SZN-1326 and SZN-043, outside of the United States. Furthermore, if we or any current or future collaborator succeed in developing any products, we anticipate marketing them in the European Union (“EU”) and other jurisdictions in addition to the United States. If approved, we or any future collaborator may hire sales representatives and conduct physician and patient association outreach activities outside of the United States. Doing business internationally involves a number of risks, including but not limited to:

•multiple, conflicting and changing laws and regulations such as those relating to privacy, data protection and cybersecurity, tax laws, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

•failure by us to obtain and maintain regulatory approvals for the use of our products in various countries;

•rejection or qualification of foreign clinical trial data by the competent authorities of other countries;

•additional potentially relevant third-party patent rights;

•complexities and difficulties in obtaining, maintaining, protecting and enforcing our intellectual property;

•difficulties in staffing and managing foreign operations;

•complexities associated with managing multiple payor reimbursement regimes, government payors or patient self-pay systems;

38

•limits in our ability to penetrate international markets;

•financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on demand and payment for products and exposure to foreign currency exchange rate fluctuations;

•natural disasters, political and economic instability, wars (including the conflict between Russia and Ukraine), terrorism, political unrest, outbreak of disease (including the COVID-19 pandemic), boycotts, trade wars and other significant events;

•certain expenses including, among others, expenses for travel, translation and insurance; and

•regulatory and compliance risks that relate to anti-corruption compliance and record-keeping that may fall within the purview of the U.S. Foreign Corrupt Practices Act, its accounting provisions or our anti-bribery provisions or provisions of anti-corruption or anti-bribery laws in other countries.

Any of these factors could harm our ongoing international operations and supply chain, as well as any future international expansion and operations and, consequently, our business, financial condition, prospects and results of operations.

Our business entails a significant risk of product liability, and our inability to obtain sufficient insurance coverage could have a material and adverse effect on our business, financial condition, results of operations and prospects.

As we conduct preclinical studies and clinical trials of SZN-1326, SZN-043, SZN-413 and other potential future product candidates, we are and will be exposed to significant product liability risks inherent in the development, testing, manufacturing and marketing of these product candidates. Product liability claims could delay or prevent completion of development programs. If we succeed in marketing products, such claims could result in an FDA investigation of the safety and effectiveness of our products, manufacturing processes and facilities or marketing programs and potentially a recall of products or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our products, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we or any current or future collaborators may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have a material and adverse effect on our business, financial condition, results of operations and prospects.

If we fail to comply with our obligations under any license, collaboration or other intellectual property-related agreements, we may be required to pay damages and could lose intellectual property rights that may be necessary for developing, commercializing and protecting our current or future technologies or product candidates or we could lose certain rights to grant sublicenses.

We are party to an exclusive license agreement with Stanford University covering patents relevant to one or more product candidates, are party to the CLA with BI related to SZN-413 and may need to obtain additional licenses from others to advance our research and development activities or allow the commercialization of our current and future product candidates we may identify and pursue. The license agreements with Stanford and BI impose, and any future license agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement or other obligations on us. For a more detailed description of the license agreements with Stanford, see the section of our Form 10-K for the year ended December 31, 2021 titled “Business—Stanford License Agreements,” and for a more detailed description of the license agreement with BI, see our Current Report on Form 8-K filed with the SEC on October 6, 2022 and Exhibit 10.1 of this Report. If we breach any of these obligations, or uses the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license. License termination could result in our inability to develop, manufacture and sell products that are covered by the licensed technology or could enable a competitor to gain access to the licensed technology. Furthermore, we may not have the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents and patent applications that we license from third parties. In certain circumstances, our licensed patent rights are subject to reimbursing licensors for their patent prosecution and maintenance costs. If our licensors and future licensors fail to prosecute, maintain, enforce and defend patents we may license, or lose rights to licensed patents or patent applications, our licensed rights may be reduced or eliminated. In such circumstances, our right to develop and commercialize any of our products or product candidates that is the subject of such licensed rights could be materially adversely affected.

Moreover, our current or future licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that it is infringing, misappropriating or otherwise violating the licensor’s intellectual property rights. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future products if infringement or misappropriation were found, those amounts could be significant. The amount of future royalty obligations will depend on the technology and intellectual property we use in products that it successfully develops and commercializes, if any. Therefore, even if we successfully develop and commercialize products, we may be unable to achieve or maintain profitability.

Moreover, disputes may arise regarding intellectual property subject to a licensing agreement, including:

39

•the scope of rights granted under the license agreement and other interpretation-related issues;

•the extent to which product candidates, technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement;

•the sublicensing of patent and other rights under our collaborative development relationships;

•our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

•the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our collaborators; and

•the priority of invention of patented technology.

In addition, the agreements under which we currently license intellectual property or technology from third parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on Our business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair its ability to maintain our current licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations, and prospects.

Risks Related to Government Regulation

Clinical development includes a lengthy and expensive process with an uncertain outcome, and results of earlier studies and trials may not be predictive of future trial results.

Our product candidates SZN-1326 and SZN-043 have begun clinical development and their risk of failure is high. It is impossible to predict when or if our candidates or any potential future product candidates will prove effective in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any product candidate, we must complete preclinical studies and then conduct extensive clinical trials to demonstrate the safety, purity, and potency, or efficacy of that product candidate in humans. Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain, particularly in light of recent observations relating to clinical trials for SZN-1326 and SZN-043. Failure can occur at any time during the development process. The results of preclinical studies and clinical trials of any of our current or potential future product candidates may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials. We initiated first-in-human trials of SZN-1326 and SZN-043 in the third quarter of 2022. We have experienced (as discussed above), and may further experience, delays in initiating or completing our clinical studies. We do not know whether planned clinical trials will be completed on schedule or at all, or whether planned clinical trials will begin on time, need to be redesigned (as we must do with SZN-1326 and have done with SZN-043), will enroll patients on time or be completed on schedule, if at all. Our development programs may be delayed for a variety of reasons, including delays related to:

•unfavorable findings or observations that cause us to pause or modify our clinical trials, as we have done to some degree with SZN-1326 and SZN-043;

•the FDA or other regulatory authorities requiring additional data or imposing other requirements before permitting initiation of a clinical trial;

•obtaining regulatory approval to commence a clinical trial;

•reaching agreement on acceptable terms with prospective CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites;

•obtaining institutional review board, or IRB, or ethics committee, or EC, approval at each clinical trial site;

•recruiting suitable patients to participate in a clinical trial;

•having patients complete a clinical trial or return for post-treatment follow-up;

•clinical trial sites deviating from trial protocol or dropping out of a trial;

•adding new clinical trial sites; or

•manufacturing sufficient quantities of our product candidates for use in clinical trials.

40

•Furthermore, we expect to rely on CROs, collaborators such as BI and clinical trial sites to ensure the proper and timely conduct of our clinical trials and, while we expect to enter into agreements governing their committed activities, we may have limited influence over their actual performance.

We could encounter delays if prescribing physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of current or potential future product candidates in lieu of prescribing existing treatments that have established safety and efficacy profiles. Further, a clinical trial may be suspended or terminated by us, our collaborators, the IRBs of the institutions in which such trials are being conducted, the Data Safety Monitoring Board for such trial or by the FDA or other regulatory authorities due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug or therapeutic biologic, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. If we experience delays in the completion of, or termination of, any clinical trial of any of our current or potential future product candidates, the commercial prospects of such product candidate will be harmed, and our ability to generate product revenue from such product candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow our product development and approval process and jeopardize our ability to commence product sales and generate revenue. Any of these occurrences may materially and adversely affect our business, financial condition, results of operations and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our current or potential future product candidates.

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, be unable to commercialize SZN-1326, SZN-043, SZN-413 or potential future product candidates.

SZN-1326, SZN-043, SZN-431 and any potential future product candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing and distribution of therapeutic biologics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required to be successfully completed in the U.S. and in many foreign jurisdictions before a new drug or therapeutic biologic can be marketed. Satisfaction of these and other regulatory requirements is costly, time-consuming, uncertain and subject to unanticipated delays. It is possible that none of the product candidates we may develop will obtain the regulatory approvals necessary for us or our potential future collaborators to begin selling them.

We have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals, including approval by the FDA and other regulatory authorities. The time required to obtain FDA and other approvals is unpredictable but typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the product candidate. The standards that the FDA and its foreign counterparts use when regulating us require judgment and can change, which makes it difficult to predict with certainty how they will be applied. Any analysis we perform of data from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative action, or from changes in regulatory policy during the period of product development, clinical trials and FDA regulatory review in the United States and other jurisdictions. It is impossible to predict whether legislative changes will be enacted, or whether FDA or foreign regulations, guidance or interpretations will be changed, or what the impact of such changes, if any, may be.

Any delay or failure in obtaining required approvals could have a material and adverse effect on our ability to generate revenue from the particular product candidate for which we are seeking approval. Further, we and our potential future collaborators may never receive approval to market and commercialize any product candidate. Even if we or a potential future collaborator obtain regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as it intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or a potential future collaborator may be subject to post-marketing testing requirements to maintain regulatory approval. If any of our product candidates prove to be ineffective, unsafe or commercially unviable, we may have to re-engineer the product candidates, and our entire pipeline could have little, if any, value, which could require us to change our focus and approach to drug discovery and therapeutic development, which would have a material and adverse effect on our business, financial condition, results of operations and prospects.

We will also be subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process varies among countries and may include all of the risks associated with FDA approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain approval may differ from that required to obtain FDA approval.

We may conduct certain of our clinical trials for our product candidates outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case its development plans will be delayed, which could materially harm its business.

We have conducted and may further conduct clinical trials for our product candidates outside the United States. For example, we have conducted Phase 1 trials of SZN-1326 and SZN-043 in Australia and New Zealand. Although the FDA may accept data from clinical

41

trials conducted outside the United States, acceptance of these data is subject to certain conditions imposed by the FDA. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will not approve the application on the basis of foreign data alone unless (i) those data are applicable to the U.S. population and U.S. medical practice; (ii) the studies were performed by clinical investigators of recognized competence; and (iii) the data are considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. For studies that are conducted only at sites outside of the United States and not subject to an IND, the FDA requires the clinical trial to have been conducted in accordance with GCPs, and the FDA must be able to validate the data from the clinical trial through an on-site inspection if it deems such inspection necessary. For such studies not subject to an IND, the FDA generally does not provide advance comments on the clinical protocols for the studies, and therefore there is an additional potential risk that the FDA could determine that the study design or protocol for a non-U.S. clinical trial was inadequate, which could require us to conduct additional clinical trials. There can be no assurance the FDA will accept data from clinical trials conducted outside of the United States. If the FDA does not accept data from our clinical trials of our product candidates, it would likely result in the need for additional clinical trials, which would be costly and time consuming and delay or permanently halt our development of our product candidates.

Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any similar foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any similar foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of Our business plan, and which may result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction or permanently halt our development of our product candidates.

Conducting clinical trials outside the United States also exposes us to additional risks, including risks associated with:

•additional foreign regulatory requirements;

•foreign exchange fluctuations;

•compliance with foreign manufacturing, customs, shipment and storage requirements;

•cultural differences in medical practice and clinical research; and

•diminished protection of intellectual property in some countries.

Even if we receive regulatory approval for any of our current or potential future product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, our current or potential future product candidates, if approved, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products.

Any regulatory approvals that we or our current or potential future collaborators obtain for SZN-1326, SZN-043, SZN-413 or any potential future product candidate may also be subject to limitations on the approved indicated uses for which a product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including “Phase 4” clinical trials, and surveillance to monitor the safety and efficacy of such product candidate. In addition, if the FDA or any other regulatory authority approves SZN-1326, SZN-043, SZN-413 or any of our future product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, import, export, advertising, promotion and recordkeeping for such product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP and good clinical practices for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with a product candidate, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

•restrictions on the marketing or manufacturing of the product candidate, withdrawal of the product candidate from the market or voluntary or mandatory product recalls;

•fines, warning letters or holds on clinical trials;

•refusal by the FDA to approve pending applications or supplements to approved applications filed by us or our strategic collaborators;

•suspension or revocation of product license approvals;

•product seizure or detention or refusal to permit the import or export of products; and

•injunctions or the imposition of civil or criminal penalties.

42

Furthermore, the FDA strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. While physicians may prescribe, in their independent professional medical judgment, products for off-label uses as the FDA does not regulate the behavior of physicians in their choice of drug treatments, the FDA does restrict manufacturer’s communications on the subject of off-label use of their products. Companies may only share truthful and non-misleading information that is otherwise consistent with a product’s FDA approved labeling. The FDA and other authorities actively enforce the laws and regulations prohibiting the promotion of off-label uses and a company that is found to have improperly promoted off-label uses may be subject to significant liability including, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. The federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined companies from engaging in off-label promotion. The FDA and other regulatory authorities have also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.

Occurrence of any of the foregoing could have a material and adverse effect on our business and results of operations. The FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business.

Risks Related to Ownership of Our Shares

Our stock price may be volatile and purchasers of our common stock could incur substantial losses.

Our stock price is likely to be volatile. As a result of this volatility, investors may not be able to sell their common stock at or above the initial public offering price. The market price for our common stock may be influenced by many factors, including the other risks described in this section of the Report titled “Risk Factors” and the following:

•our ability, or the ability of our business partners, to advance SZN-1326, SZN-043, SZN-413 or potential future product candidates into the clinic;

•results of preclinical studies for SZN-1326, SZN-043, SZN-413 or potential future product candidates, or those of our competitors or current and potential future collaborators;

•the impact of the ongoing COVID-19 pandemic on our business;

•regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to our future products;

•the success of competitive products or technologies;

•introductions and announcements of new products by us, our future commercialization collaborators, or our competitors, and the timing of these introductions or announcements;

•actions taken by regulatory authorities with respect to our future products, clinical trials, manufacturing process or sales and marketing terms;

•actual or anticipated variations in our financial results or those of companies that are perceived to be similar to us;

•the success of our efforts to acquire or in-license additional technologies, products or product candidates;

•developments concerning any future collaborations, including, but not limited to, those with our sources of manufacturing supply and our commercialization collaborators;

•market conditions in the pharmaceutical and biotechnology sectors;

•announcements by us or our competitors of significant acquisitions, strategic alliances, joint ventures or capital commitments;

•developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our products;

•our ability or inability to raise additional capital and the terms on which we raise it;

•the recruitment or departure of key personnel;

•changes in the structure of healthcare payment systems;

43

•actual or anticipated changes in earnings estimates or changes in stock market analyst recommendations regarding our common stock, other comparable companies or our industry generally;

•our failure or the failure of our competitors to meet analysts’ projections or guidance that we or our competitors may give to the market;

•fluctuations in the valuation of companies perceived by investors to be comparable to us;

•announcement and expectation of additional financing efforts;

•speculation in the press or investment community;

•trading volume of our common stock;

•sales of our common stock by us or our stockholders;

•the concentrated ownership of our common stock;

•changes in accounting principles;

•terrorist acts, acts of war or periods of widespread civil unrest;

•natural disasters, public health crises and other calamities; and

•general economic, industry and market conditions.

In addition, the stock markets in general, and the markets for pharmaceutical, biopharmaceutical and biotechnology stocks in particular, have experienced extreme volatility that has been often unrelated to the operating performance of the issuer. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.

Because our management will have flexibility in allocating our cash, you may not agree with how we use them and the cash may not be invested successfully.

We currently expect to use our cash, primarily obtained through prior stock offerings, to fund the development of SZN-1326 and SZN-043 through the resumption and continuation of first in human trials and to fund our other ongoing research and discovery programs, as well as for working capital and other general corporate purposes. We may also use a portion of our cash to in-license, acquire or invest in complementary businesses, technologies, products or assets. However, other than our CLA with BI, we have no current commitments or obligations to do so. Therefore, our management will have flexibility in allocating our cash. Accordingly, you will be relying on the judgment of our management with regard to the allocation of our cash, and you will not have the opportunity, as part of your investment decision, to assess whether the cash is being allocated appropriately. It is possible that the cash will be invested in a way that does not yield a favorable, or any, return for our company.

WARRANT AGREEMENT

by and between

CONSONANCE-HFW ACQUISITION CORP.

and

CONTINENTAL STOCK TRANSFER & TRUST COMPANY

Dated August 11, 2021

THIS WARRANT AGREEMENT (this “Agreement”), dated August 11, 2021, is by and between Consonance-HFW Acquisition Corp., a Cayman Islands exempted company (the “Company”), and Continental Stock Transfer & Trust Company, a New York limited purpose trust company, as warrant agent (in such capacity, the “Warrant Agent”).

WHEREAS, on April 15, 2021, the Company entered into those certain Subscription Agreements with the Investors named therein pursuant to which the Investors agreed to purchase an aggregate of 12,020,000 units (the “Private Placement Units”) at a purchase price of $10.00 per Private Placement Unit. The Private Placement Units include an aggregate of 4,006,667 private placement warrants, bearing the legend set forth in Exhibit B hereto (the “Private Placement Warrants”). Each Private Placement Unit includes one share of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), and one-third of one Private Placement Warrant. The Units are being offered to facilitate the subscriptions, however, the shares of Common Stock and the Private Placement Warrants which comprise the Units are not attached and will trade separately without any instruction or detachment obligations on the part of the Investors, the Company or the Warrant Agent. Each whole Private Placement Warrant entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment as described herein and only whole Warrants will be exercisable;

WHEREAS, the Subscription Agreement provides that the Company will file with the Securities and Exchange Commission (the “Commission”) a registration statement and a prospectus (the “Prospectus”), for the registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the shares of Common Stock included in the Private Placement Units, the Private Placement Warrants and the shares of Common Stock underlying the Private Placement Warrants (collectively, the “Private Placement Securities”); and

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Private Placement Warrants; and

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent and the holders of the Private Placement Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Private Placement Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1.Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Private Placement Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

2.Warrants.

2.1.Form of Warrant. Each Private Placement Warrant shall initially be issued in registered form only.

2.2.Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a certificated Private Placement Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3.Registration.

2.3.1.Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”), for the registration of original issuance and the registration of transfer of the Private Placement Warrants. Upon the initial issuance of the Private Placement Warrants in book- entry form, the Warrant Agent shall issue and register the Private Placement Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial interests in the Private Placement Warrants, as applicable, shall be shown on, and the transfer of such ownership shall be effected through, records maintained by institutions that have accounts with The Depository Trust Company (the “Depositary”) (such institution, with respect to a Private Placement Warrant in its account, a “Participant”).

If the Depositary subsequently ceases to make its book-entry settlement system available for the applicable Private Placement Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Private Placement Warrants are not eligible for, or it is no longer necessary to have the Private Placement Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each book- entry Private Placement Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such Private Placement Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto as Exhibit A.

Physical certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer, Chief Financial Officer or other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any Private Placement Warrant shall have ceased to serve in the capacity in which such person signed the Private Placement Warrant before such Private Placement Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

2.3.2.Registered Holder. Prior to due presentment for registration of transfer of any Private Placement Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Private Placement Warrant is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Private Placement Warrants represented thereby, for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2

2.4.Separate Trading of Stock and Units. The shares of Common Stock and Private Placement Warrants comprising the Private Placement Units shall trade separately. It is expected that the Private Placement Securities will be listed for trading on the Nasdaq Stock Market (the “Nasdaq”) following the date of the Prospectus, which shall be a date other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business (a “Business Day”).

2.5.Fractional Warrants. The Company shall not issue fractional Private Placement Warrants other than as part of the Private Placement Units.

3.Terms and Exercise of Warrants.

3.1.Warrant Price. Each whole Private Placement Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Private Placement Warrant and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Private Placement Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder) described in the prior sentence at which shares of Common Stock may be purchased at the time a Private Placement Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than fifteen (15) Business Days (unless otherwise required by the Commission, any national securities exchange on which the Private Placement Warrants are listed or applicable law); provided that the Company shall provide at least five (5) days’ prior written notice of such reduction to Registered Holders of the Private Placement Warrants; and provided further, that any such reduction shall be identical among all of the Private Placement Warrants and those certain other warrants issued by the Company under that certain Registration Statement for Form S-1 No. 333-249394 declared effective by the Commission on November 18, 2021 (the “IPO Warrants”) in connection with the Company’s initial public offering (the “IPO”).

3.2.Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”) commencing on November 23, 2021 and terminating at 5:00 p.m., New York City time on the date that is fifth (5th) anniversary of the date hereof (the “Expiration Date”); provided, however, that the exercise of any Private Placement Warrant shall be subject to the satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration statement or a valid exemption therefrom being available. Private Placement Warrants not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Private Placement Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior written notice of any such extension to Registered Holders of the Private Placement Warrants and, provided further that any such extension shall be identical in duration among all of the Private Placement Warrants and the IPO Warrants.

3.3.Exercise of Warrants.

3.3.1.Payment. Subject to the provisions of the Private Placement Warrant and this Agreement, a Private Placement Warrant may be exercised by the Registered Holder thereof by delivering to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Private Placement Warrants to be exercised, or, in the case of a Private Placement

Warrant represented by a book-entry, the Private Placement Warrants to be exercised (the “Book-Entry Warrants”) on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to purchase (“Election to Purchase”) any shares of Common Stock pursuant to the exercise of a Private Placement Warrant, properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate or, in the case of a Book-Entry Warrant, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) the payment in full of the Warrant Price for each share of Common Stock as to which the Private Placement Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Private Placement Warrant, the exchange of the Private Placement Warrant for the shares of Common Stock and the issuance of such shares of Common Stock, in lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent or as provided in Section 7.4 hereof.

3.3.2.Issuance of Shares on Exercise. As soon as practicable after the exercise of any Private Placement Warrant and the clearance of the funds in payment of the Warrant Price (unless exercised pursuant to Section 7.4), the Company shall issue to the Registered Holder of such Private Placement Warrant a book-entry position or certificate, as applicable, for the number of shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company, and if such Private Placement Warrant shall not have been exercised in full, a new book-entry position or countersigned Private Placement Warrant, as applicable, for the number of shares as to which such Private Placement Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Private Placement Warrant and shall have no obligation to settle such Private Placement Warrant exercise unless a registration statement under the Securities Act with respect to the shares of Common Stock underlying the Private Placement Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations under Section 7.4 or a valid exemption from registration is available. No Private Placement Warrant shall be exercisable and the Company shall not be obligated to issue shares of Common Stock upon exercise of a Private Placement Warrant unless the shares of Common Stock issuable upon such Private Placement Warrant exercise have been registered, qualified or deemed to be exempt from registration or qualification under the securities laws of the state of residence of the Registered Holder of the Private Placement Warrants. Subject to Section 4.5 of this Agreement, a Registered Holder of Private Placement Warrants may exercise its Private Placement Warrants only for a whole number of shares of Common Stock. The Company may require holders of Private Placement Warrants registered on an effective registration statement to settle the Private Placement Warrant on a “cashless basis” pursuant to Section

7.4. If, by reason of any exercise of Private Placement Warrants on a “cashless basis”, the holder of any Private Placement Warrant would be entitled, upon the exercise of such Private Placement Warrant, to receive a fractional interest in a share of Common Stock, the Company shall round down to the nearest whole number, the number of shares of Common Stock to be issued to such holder.

3.3.3.Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Private Placement Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

3.3.4.Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is issued and who is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which the Private Placement Warrant, or book-entry position representing such Private Placement Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Private Placement Warrant, except that, if the date of such surrender and payment is a date when the register of

4

members of

5

the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share transfer books or book- entry system are open.

3.3.5.Maximum Percentage. A holder of a Private Placement Warrant may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however, no holder of a Private Placement Warrant shall be subject to this subsection

3.3.5 unless he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the holder’s Private Placement Warrant, and such holder shall not have the right to exercise such Private Placement Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of the Private Placement Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Private Placement Warrant beneficially owned by such person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes of the Private Placement Warrant, in determining the number of outstanding shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or Continental Stock Transfer & Trust Company, as transfer agent (in such capacity, the “Transfer Agent”), setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written request of the holder of the Private Placement Private Placement Warrant, the Company shall, within two (2) Business Days, confirm orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of issued and outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder and its affiliates since the date as of which such number of issued and outstanding shares of Common Stock was reported. By written notice to the Company, the holder of a Private Placement Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first (61st) day after such notice is delivered to the Company.

4.Adjustments.

4.1.Share Capitalizations.

4.1.1.Sub-Divisions. If after the date hereof, and subject to the provisions of Section 4.5 below, the number of issued and outstanding shares of Common Stock is increased by a capitalization or share dividend of shares of Common Stock, or by a sub-division of shares of Common Stock or other similar event, then, on the effective date of such share capitalization or share dividend, sub-divisions or similar event, the number of shares of Common Stock issuable on exercise of each Private Placement Warrant shall be increased in proportion to such increase in the issued and

6

outstanding

7

shares of Common Stock. A rights offering made to all or substantially all holders of shares of Common Stock entitling holders to purchase shares of Common Stock at a price less than the Historical Fair Market Value (as defined below) shall be deemed a share dividend of a number of shares of Common Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for shares of Common Stock) multiplied by (ii) one (1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the Historical Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for shares of Common Stock, in determining the price payable for shares of Common Stock, there shall be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Historical Fair Market Value” means the volume weighted average price of the shares of Common Stock during the ten (10) trading day period ending on the trading day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights. No shares of Common Stock shall be issued at less than their par value.

4.1.2.Extraordinary Dividends. If the Company, at any time while the Private Placement Warrants are outstanding and unexpired, pays to all or substantially all of the holders of the shares of Common Stock a dividend or make a distribution in cash, securities or other assets on account of such shares of Common Stock (or other shares into which the Private Placement Warrants are convertible), other than (a) as described in subsection 4.1.1 above or (b) Cash Dividends (as defined below), any such non-excluded event being referred to herein as an “Extraordinary Dividend”, then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount of cash and/or the fair market value (as determined by the Company’s board of directors (the “Board”), in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes of this subsection 4.1.2, “Cash Dividends” means any cash dividend or cash distribution which, when combined on a per share basis with all other cash dividends and cash distributions paid on the shares of Common Stock during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise of each Private Placement Warrant but only with respect to the amount of aggregate cash dividends and cash distributions equal to or less than $0.50 per share of Common Stock).

4.2.Aggregation of Shares. If after the date hereof, and subject to the provisions of Section 4.5 hereof, the number of issued and outstanding shares of Common Stock is decreased by a consolidation, combination, reverse share split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse share split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Private Placement Warrant shall be decreased in proportion to such decrease in issued and outstanding shares of Common Stock.

4.3.Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Private Placement Warrants is adjusted, as provided in subsection 4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Private Placement Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

8

4.4.[Reserved.]

4.5.Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and outstanding shares of Common Stock (other than a change under Section 4.1 or that solely affects the par value of such shares of Common Stock), or in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the issued and outstanding shares of Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which the Company is dissolved, the holders of the Private Placement Warrants shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Private Placement Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Private Placement Warrants would have received if such holder had exercised his, her or its Private Placement Warrant(s) immediately prior to such event (the “Alternative Issuance”); provided, however, that (i) if the holders of the shares of Common Stock were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets constituting the Alternative Issuance for which each Private Placement Warrant shall become exercisable shall be deemed to be the weighted average of the kind and amount received per share by the holders of the shares of Common Stock in such consolidation or merger that affirmatively make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of the shares of Common Stock (other than a tender, exchange or redemption offer made by the Company in connection with redemption rights held by stockholders of the Company as provided for in the Company’s certificate of incorporation under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the issued and outstanding shares of Common Stock, the holder of a Private Placement Warrant shall be entitled to receive as the Alternative Issuance, the highest amount of cash, securities or other property to which such holder would actually have been entitled as a shareholder if such Private Placement Warrant holder had exercised the Private Placement Warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the shares of Common Stock held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in this Section 4; provided further that if less than 70% of the consideration receivable by the holders of the shares of Common Stock in the applicable event is payable in the form of shares in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises the Private Placement Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars) equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration (as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes Warrant Value” means the value of a Private Placement Warrant immediately prior to the consummation of the applicable event based on the Black- Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (assuming zero

9

dividends) (“Bloomberg”). For purposes of calculating such amount, (i) Section 6 of this Agreement shall be taken into account, (ii) the price of each share of Common Stock shall be the volume weighted average price of the shares of Common Stock during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event, (iii) the assumed volatility shall be the ninety (90) day volatility obtained from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable event and (iv) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining term of the Private Placement Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the shares of Common Stock consists exclusively of cash, the amount of such cash per share of Common Stock, and (ii) in all other cases, the volume weighted average price of the shares of Common Stock during the ten (10) trading day period ending on the trading day prior to the effective date of the applicable event. If any reclassification or reorganization also results in a change in shares of Common Stock covered by subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Section 4.3 and this Section 4.5. The provisions of this Section 4.5 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event shall the Warrant Price be reduced to less than the par value per share issuable upon exercise of such Private Placement Warrant.

4.6.Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Private Placement Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Private Placement Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Section 4.1, Section 4.3 or Section 4.5, the Company shall give written notice of the occurrence of such event to each holder of a Private Placement Warrant, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.7.No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares upon the exercise of Private Placement Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Private Placement Warrant would be entitled, upon the exercise of such Private Placement Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to such holder.

4.8.Form of Warrant. The form of Private Placement Warrant need not be changed because of any adjustment pursuant to this Section 4, and Private Placement Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Private Placement Warrants initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Private Placement Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Private Placement Warrant or otherwise, may be in the form as so changed.

5.Transfer and Exchange of Warrants.

5.1.Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Private Placement Warrant upon the Warrant Register, upon surrender of such Private Placement Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Private Placement

10

Warrant representing an equal aggregate number of Private Placement Warrants shall be issued and the old Private Placement Warrant shall be cancelled by the Warrant Agent. In the case of certificated Private Placement Warrants, the Private Placement Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon request.

5.2.Procedure for Surrender of Warrants. Private Placement Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Private Placement Warrants as requested by the Registered Holder of the Private Placement Warrants so surrendered, representing an equal aggregate number of Private Placement Warrants; provided, however, that except as otherwise provided herein or with respect to any Book-Entry Warrant, each Book- Entry Warrant may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depository, or to a nominee of a successor depository; provided further, however that in the event that a Private Placement Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Private Placement Warrant and issue new Private Placement Warrants in exchange thereof until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Private Placement Warrants must also bear a restrictive legend.

5.3.Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in the issuance of a warrant certificate or book- entry position for a fraction of a warrant, except as part of the Private Placement Units.

5.4.Service Charges. No service charge shall be made for any exchange or registration of transfer of Private Placement Warrants.

5.5.Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Private Placement Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Private Placement Warrants duly executed on behalf of the Company for such purpose.

6.Redemption.

6.1.Redemption of Warrants for Cash. Not less than all of the outstanding Private Placement Warrants may be redeemed, at the option of the Company, at any time from and after the 366 day anniversary of the date of this Agreement and on or prior to the Expiration Date, at the office of the Warrant Agent, upon notice to the Registered Holders of the Private Placement Warrants, as described in Section 6.3 below, at a Redemption Price of $0.01 per Private Placement Warrant, provided that (a) the Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof) and (b) there is an effective registration statement covering the resale of the shares of Common Stock issuable upon exercise of the Private Placement Warrants, and a current prospectus relating thereto, available throughout the thirty (30)-day Redemption Period (as defined in Section 6.3 below).

6.2.Redemption of Warrants for Shares. Not less than all of the outstanding Private Placement Warrants may be redeemed, at the option of the Company, at any time from and after the 366 day anniversary of the date of this Agreement and on or prior to the Expiration Date, at the office of the Warrant Agent, upon notice to the Registered Holders of the Private Placement Warrants, as described in Section 6.3 below, at a Redemption Price of $0.10 per Private Placement Warrant, provided that (i) the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4

11

hereof and (ii) if the Reference Value is less than $18.00 per share (subject to adjustment in compliance with Section 4 hereof), the IPO Warrants and those certain other privately placed warrants issued by the Company in connection with the IPO are also concurrently called for redemption on the same terms as the outstanding Private Placement Warrants (subject to the terms and conditions of that certain Warrant Agreement entered into between the Company and the Warrant Agent dated November 18, 2020). During the thirty (30)-day Redemption Period in connection with a redemption pursuant to this Section 6.2, Registered Holders of the Private Placement Warrants may elect to exercise their Private Placement Warrants on a “cashless basis” and receive a number of shares of Common Stock determined by reference to the table below, based on the Redemption Date (calculated for purposes of the table as the period to expiration of the Private Placement Warrants) and the “Redemption Fair Market Value” (as such term is defined in this Section 6.2) (a “Make-Whole Exercise”). Solely for purposes of this Section6.2, the “Redemption Fair Market Value” shall mean the volume weighted average price of the shares of Common Stock for the ten (10) trading days immediately following the date on which notice of redemption pursuant to this Section 6.2 is sent to the Registered Holders. In connection with any redemption pursuant to this Section 6.2, the Company shall provide the Registered Holders with the Redemption Fair Market Value no later than one (1) Business Day after the ten (10) trading day period described above ends.

The exact Redemption Fair Market Value and Redemption Date may not be set forth in the table above, in which case, if the Redemption Fair Market Value is between two values in the table or the Redemption Date is between two redemption dates in the table, the number of shares of Common Stock to be issued for each Private Placement Warrant exercised in a Make-Whole Exercise shall be determined by a straight-line interpolation between the number of shares set forth for the higher and lower Redemption Fair Market Values and the earlier and later redemption dates, as applicable, based on a 365- or 366-day year, as applicable.

The share prices set forth in the column headings of the table above shall be adjusted as of any date on which the number of shares of Common Stock issuable upon exercise of a Private Placement Warrant or the Exercise Price is adjusted pursuant to Section 4 hereof. If the number of shares issuable

12

upon exercise of a Private Placement Warrant is adjusted pursuant to Section 4 hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the number of shares of Common Stock deliverable upon exercise of a Private Placement Warrant immediately prior to such adjustment and the denominator of which is the number of shares of Common Stock deliverable upon exercise of a Private Placement Warrant as so adjusted. The number of shares of Common Stock in the table above shall be adjusted in the same manner and at the same time as the number of shares of Common Stock issuable upon exercise of a Private Placement Warrant. If the Exercise Price of a Private Placement Warrant is adjusted pursuant to Section 4.1.2 hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment less the decrease in the Exercise Price pursuant to such Exercise Price adjustment. In no event shall the number of shares of Common Stock issued in connection with a Make-Whole Exercise exceed 0.361 shares of Common Stock per Private Placement Warrant (subject to adjustment).

6.3.Date Fixed for, and Notice of, Redemption; Redemption Price; ReferenceValue. In the event that the Company elects to redeem the Private Placement Warrants pursuant to Section 6.1 or Section 6.2, the Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of the Private Placement Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice. As used in this Agreement, (a) “Redemption Price” shall mean the price per Private Placement Warrant at which any Private Placement Warrants are redeemed pursuant to Section 6.1 or Section 6.2 and (b) “Reference Value” shall mean the last reported sales price of the shares of Common Stock for any twenty (20) trading days within the thirty (30) trading-day period ending on the third (3rd) trading day prior to the date on which notice of the redemption is given.

6.4.Exercise After Notice of Redemption. The Private Placement Warrants may be exercised for cash (or on a “cashless basis” in accordance with Section 6.2 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section 6.3 hereof and prior to the Redemption Date. On and after the Redemption Date, the record holder of the Private Placement Warrants shall have no further rights except to receive, upon surrender of the Private Placement Warrants, the Redemption Price.

7.Other Provisions Relating to Rights of Holders of Warrants.

7.1.No Rights as Stockholder. A Private Placement Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the appointment of directors of the Company or any other matter.

7.2.Lost, Stolen, Mutilated, or Destroyed Warrants. If any Private Placement Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated Private Placement Warrant, include the surrender thereof), issue a new Private Placement Warrant of like denomination, tenor, and date as the Private Placement Warrant so lost, stolen, mutilated, or destroyed. Any such new Private Placement Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Private Placement Warrant shall be at any time enforceable by anyone.

13

7.3.Reservation of Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit the exercise in full of all outstanding Private Placement Warrants issued pursuant to this Agreement.

7.4.Registration of Shares; Cashless Exercise at Company’s Option.

7.4.1.Registration of the Shares. The Company agrees that as soon as practicable, but in no event later than twenty (20) Business Days after the date hereof, it shall use its commercially reasonable efforts to file with the Commission a registration statement for the registration, under the Securities Act, of the Private Placement Securities. The Company shall use its commercially reasonable efforts to cause the same to become effective within sixty (60) Business Days following the date hereof and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration or redemption of the Private Placement Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective by the sixtieth (60th) Business Day following the date hereof, holders of the Private Placement Warrants shall have the right, during the period beginning on the sixty-first (61st) Business Day after the date hereof and ending upon such registration statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained an effective registration statement covering the resale of the shares of Common Stock issuable upon exercise of the Private Placement Warrants, to exercise such Private Placement Warrants on a “cashless basis,” by exchanging the Private Placement Warrants (in accordance with Section 3(a)(9) of the Securities Act or another exemption) for that number of shares of Common Stock equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of shares of Common Stock underlying the Private Placement Warrants, multiplied by the excess of the “Fair Market Value” (as defined below) over the Warrant Price by (y) the Fair Market Value and (B) 0.361. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the average last reported sales price of the shares of Common Stock for the ten (10) trading day period ending on the third (3rd) trading day prior to the date that notice of exercise is received by the Warrant Agent from the holder of such Private Placement Warrants or its securities broker or intermediary. The date that notice of “cashless exercise” is received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise” of a Private Placement Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of the Private Placement Warrants on a “cashless basis” in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and, accordingly, shall not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of doubt, unless and until all of the Private Placement Warrants have been exercised or have expired, the Company shall continue to be obligated to comply with its registration obligations under the first three sentences of this subsection 7.4.1.

7.4.2.Cashless Exercise at Company’s Option. If the shares of Common Stock are at the time of any exercise of a Private Placement Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, (i) require holders of such Private Placement Warrants who exercise such Private Placement Warrants to exercise such Private Placement Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the shares of Common

14

Stock issuable upon exercise of the Private Placement Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its commercially reasonable efforts to register or qualify for sale the shares of Common Stock issuable upon exercise of the Private Placement Warrants under applicable blue sky laws to the extent an exemption is not available.

8.Concerning the Warrant Agent and Other Matters.

8.1.Payment of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of the Private Placement Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Private Placement Warrants or such shares.

8.2.Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1.Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of a Private Placement Warrant (who shall, with such notice, submit his, her or its Private Placement Warrant for inspection by the Company), then the holder of any Private Placement Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation or other entity organized and existing under the laws of the State of New York, in good standing and having its principal office in the United States of America, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

8.2.2.Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer Agent for the shares of Common Stock not later than the effective date of any such appointment.

8.2.3.Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

15

8.3.Fees and Expenses of Warrant Agent.

8.3.1.Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall, pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

8.3.2.Further Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged, and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

8.4.Liability of Warrant Agent.

8.4.1.Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chairman of the Board, Chief Executive Officer or Chief Financial Officer and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

8.4.2.Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, fraud or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, out-of-pocket costs and reasonable outside counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith.

8.4.3.Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Private Placement Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Private Placement Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Private Placement Warrant or as to whether any shares of Common Stock shall, when issued, be valid and fully paid and nonassessable.

8.5.Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Private Placement Warrants exercised and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of the Private Placement Warrants.

8.6.Waiver. The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of the date hereof, by and between the Company and Continental Stock Transfer & Trust Company as trustee thereunder) and hereby agrees not to seek

16

recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust Account.

9.Miscellaneous Provisions.

17

Any person or entity purchasing or otherwise acquiring any interest in the Private Placement Warrants shall be deemed to have notice of and to have consented to the forum provisions in this Section 9.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the name of any Private Placement Warrant holder, such Private Placement Warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of New York or the United States District Court for the Southern District of New York in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such Private Placement Warrant holder in any such enforcement action by service upon such Private Placement Warrant holder’s counsel in the foreign action as agent for such Private Placement Warrant holder.

9.4.Persons Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person, corporation or other entity other than the parties hereto and the Registered Holders of the Private Placement Warrants any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the Registered Holders of the Private Placement Warrants.

9.5.Examination of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the Warrant Agent in the United States of America, for inspection by the Registered Holder of any Private Placement Warrant. The Warrant Agent may require any such holder to submit such holder’s Private Placement Warrant for inspection by the Warrant Agent.

9.6.Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

9.7.Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the interpretation thereof.

9.8.Amendments. This Agreement may be amended by the parties hereto without the consent of any Registered Holder for the purpose of (i) curing any ambiguity or to correct any mistake, including to conform the provisions hereof to the description of the terms of the Private Placement Warrants and this Agreement set forth in the Prospectus, or defective provision contained herein, (ii) amending the definition of “Cash Dividend” as contemplated by and in accordance with the second sentence of subsection 4.1.2 that the parties deem shall not adversely affect the rights of the Registered Holders under this Agreement or (iii) adding or changing any provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the rights of the Registered Holders under this Agreement. All other modifications or amendments, including any modification or amendment to increase the Warrant Price or shorten the Exercise Period, to the terms of the Private Placement Warrants, shall require the vote or written consent of the Registered Holders of 50% of the then-outstanding Private Placement Warrants. Notwithstanding the foregoing, the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Section 3.1 and Section 3.2, respectively, without the consent of the Registered Holders.

9.9.Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or

18

unenforceable term or provision, the parties hereto intend that there shall be added as a part of this

19

Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

[Form of Warrant Certificate] [Reverse]

The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive [ ] Ordinary Shares and are issued or to be issued pursuant to a Warrant Agreement dated as of [ ], 2021 (the “Warrant Agreement”), duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

Warrants may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of Election to Purchase set forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the Ordinary Shares is current, except through “cashless exercise” as provided for in the Warrant Agreement.

The Warrant Agreement provides that upon the occurrence of certain events the number of Ordinary Shares issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest in an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number of Ordinary Shares to be issued to the holder of the Warrant.

Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

Upon due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company.

Exhibit 4.7

DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF

THE SECURITIES EXCHANGE ACT OF 1934

The following is a summary description of the securities of Surrozen, Inc. and is based on the provisions of our Certificate of Incorporation, or the Certificate of Incorporation, our Bylaws, or the Bylaws, and the applicable provisions of the Delaware General Corporation Law, or the DGCL. This information may not be complete in all respects and is qualified entirely by reference to the provisions of the Certificate of Incorporation and the Bylaws, copies of which have been filed as exhibits to our Quarterly Report on Form 10-Q to which this exhibit is attached, and the applicable provisions of the DGCL.

General

Our authorized capital stock consists of 500,000,000 shares of common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share.

Common Stock

Voting Rights

Holders of our common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. The Certificate of Incorporation prohibits cumulative voting for the election of directors unless otherwise provided by law.

Dividend Rights

Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of our common stock are entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board of directors may determine.

No Preemptive or Similar Rights

Our common stock will not be entitled to preemptive rights, and are not subject to conversion, redemption or sinking fund provisions.

Right to Receive Liquidation Distributions

If we become subject to a liquidation, dissolution or winding-up, the assets legally available for distribution to the stockholders would be distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

Fully Paid and Non-Assessable

All of the outstanding shares of our common stock are fully paid and non-assessable.

Preferred Stock

Our board of directors is authorized, subject to limitations prescribed by Delaware law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series and to fix the designation, powers, preferences and rights of the shares of each series and any of its qualifications, limitations or restrictions. The number of authorized shares of preferred stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the voting power of the stock of our company entitled to vote thereon, without a separate vote of the holders of the preferred stock, or of any series thereof, unless a vote of any such holders is required pursuant to the terms of any certificate of designation filed with respect to any series of preferred stock. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. The issuance of preferred stock, while providing flexibility in connection with financings, possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring, discouraging or preventing a change in control of our company, may adversely

affect the market price of our common stock and the voting and other rights of the holders of common stock, and may reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation. As of September 30, 2022, we have no shares of preferred stock issued and outstanding. We have no present plans to issue any shares of preferred stock.

Warrants

As of September 30, 2022, there were 7,217,991 warrants to purchase common stock outstanding, consisting of 3,066,667 public warrants, or the Public Warrants, 144,667 private placement warrants, or the Private Placement Warrants, and 4,006,657 PIPE warrants, or the PIPE Warrants.

Public Warrants

Each whole Public Warrant entitles the registered holder to purchase one share of our common stock at a price of $11.50 per share, subject to adjustment as discussed below, provided that we have an effective registration statement under the Securities Act covering the common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or we permit holders to exercise their Public Warrants on a cashless basis) and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. Pursuant to that certain warrant agreement, dated November 18, 2020, by and between us and Continental Stock Transfer & Trust Company, or the Continental Warrant Agreement, a Public Warrant holder may exercise its Public Warrants only for a whole number of common stock. This means only a whole Public Warrant may be exercised at a given time by a Public Warrant holder. No fractional Public Warrants will be issued upon separation of the shares and only whole Public Warrants will trade. Accordingly, unless you purchase at least three shares, you will not be able to receive or trade a whole Public Warrant. The Public Warrants will expire on August 11, 2026 at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We will not be obligated to deliver any common stock pursuant to the exercise of a Public Warrant and will have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act with respect to the common stock underlying the Public Warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration, or a valid exemption from registration is available. No Public Warrant will be exercisable and we will not be obligated to issue a common stock upon exercise of a Public Warrant unless the common stock issuable upon such Public Warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the Public Warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a Public Warrant, the holder of such Public Warrant will not be entitled to exercise such Public Warrant and such Public Warrant may have no value and expire worthless. In no event will we be required to net cash settle any Public Warrant. In the event that a registration statement is not effective for the exercised Public Warrants, the purchaser of a share containing such Public Warrant will have paid the full purchase price for the share solely for the common stock underlying such unit.

We will use our commercially reasonable efforts to maintain the effectiveness of a registration statement covering the common stock issuable upon exercise of the Public Warrants and a current prospectus relating to those common stock until the Public Warrants expire or are redeemed, as specified in the Continental Warrant Agreement; provided that if our common stock are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, we may, at our option, require holders of Public Warrants who exercise their Public Warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event we so appoint, we will not be required to file or maintain in effect a registration statement.

Redemption of Public Warrants for cash when the price per common stock equals or exceeds $18.00. After the Public Warrants became exercisable, we may call the Public Warrants for redemption (except as described herein with respect to the private placement Public Warrants):

•in whole and not in part;

•at a price of $0.01 per Public Warrant;

•upon not less than 30 days’ prior written notice of redemption to each Public Warrant holder; and

•if, and only if, the closing price of our common stock equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which notice of the redemption is given to the Public Warrant holders, or the Reference Value.

We will not redeem the Public Warrants as described above unless a registration statement under the Securities Act covering the issuance of the common stock issuable upon exercise of the Public Warrants is then effective and a current prospectus relating to those shares is available throughout the 30-day redemption period. If and when the Public Warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. As a result, we may redeem the Public Warrants as set forth above even if the holders are otherwise unable to exercise the Public Warrants.

We have established the last of the redemption criteria discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the Public Warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the Public Warrants, each Public Warrant holder will be entitled to exercise his, her or its Public Warrant prior to the scheduled redemption date. However, the price of our common stock may fall below the $18.00 redemption trigger price (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and the like) as well as the $11.50 (for whole shares) Public Warrant exercise price after the redemption notice is issued.

Redemption of Public Warrants for Common Stock. when the price per common stock equals or exceeds $10.00. Once the Public Warrants become exercisable, we may redeem the outstanding Public Warrants:

•in whole and not in part;

•at $0.10 per Public Warrant upon a minimum of 30 days’ prior written notice of redemption; provided that during such 30 day period holders will be able to exercise their Public Warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table below, based on the redemption date and the “fair market value” of our common stock (as defined below) except as otherwise described below; provided, further, that if the Public Warrants are not exercised on a cashless basis or otherwise during such 30 day period, we shall redeem such Public Warrants for $0.10 per share;

•if, and only if, the Reference Value (as defined above under “Redemption of Public Warrants for Cash When the Price per Common Stock Equals or Exceeds $18.00”) equals or exceeds $10.00 per share (as adjusted for share subdivisions, share dividends, reorganizations, recapitalizations and the like) on the trading day before we send the notice of redemption to the Public Warrant holders; and

•if the Reference Value is less than $18.00 per share (as adjusted for share subdivisions, share dividends, reorganizations, recapitalizations and the like), the private placement Public Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

The numbers in the table below represent the number of common stock that a Public Warrant holder will receive upon exercise in connection with a redemption by us pursuant to this redemption feature, based on the “fair market value” of our common stock on the corresponding redemption date (assuming holders elect to exercise their Public Warrants and such Public Warrants are not redeemed for $0.10 per Public Warrant), determined based on volume-weighted average price of our common stock as reported during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of Public Warrants, and the number of months that the corresponding redemption date precedes the expiration date of the Public Warrants, each as set forth in the table below. We will provide our Public Warrant holders with the final fair market value no later than one business day after the 10-trading day period described above ends.

The share prices set forth in the column headings of the table below will be adjusted as of any date on which the number of shares issuable upon exercise of a Public Warrant or the exercise price of the Public Warrant is adjusted as set forth under the heading “—Anti-dilution Adjustments” below. If the number of shares issuable upon exercise of a Public Warrant is adjusted, the adjusted share prices in the column headings will equal the share prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the exercise price of the Public Warrant after such adjustment and the denominator of which is the price of the Public Warrant immediately prior to such adjustment. In such an event, the number of shares in the table below shall be adjusted by multiplying such share amounts by a fraction, the numerator of which is the number of shares deliverable upon exercise of a Public Warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a Public Warrant as so adjusted.

The exact fair market value and redemption date may not be set forth in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two redemption dates in the table, the number of common stock to be issued for each Public Warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the volume-weighted average price of our common stock as reported during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of the Public Warrants is $11.00 per share, and at such time there are 57 months until the expiration of the Public Warrants, holders may choose to, in connection with this redemption feature, exercise their Public Warrants for 0.277 common stock for each whole Public Warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if the volume-weighted average price of our common stock as reported during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of the Public Warrants

is $13.50 per share, and at such time there are 38 months until the expiration of the Public Warrants, holders may choose to, in connection with this redemption feature, exercise their Public Warrants for 0.298 common stock for each whole Public Warrant. In no event will the Public Warrants be exercisable in connection with this redemption feature for more than 0.361 common stock per Public Warrant (subject to adjustment).

This redemption feature is structured to allow for all of the outstanding Public Warrants to be redeemed when our common stock are trading at or above $10.00 per share, which may be at a time when the trading price of our common stock is below the exercise price of the Public Warrants. We have established this redemption feature to provide us with the flexibility to redeem the Public Warrants without the Public Warrants having to reach the $18.00 per share threshold set forth above under “—Redemption of Public Warrants for cash when the price per Common Stock equals or exceeds $18.00.” Holders choosing to exercise their Public Warrants in connection with a redemption pursuant to this feature will, in effect, receive a number of shares for their Public Warrants based on an option pricing model with a fixed volatility input as of the date of any applicable prospectus. This redemption right provides us with an additional mechanism by which to redeem all of the outstanding Public Warrants, and therefore have certainty as to our capital structure as the Public Warrants would no longer be outstanding and would have been exercised or redeemed. We will be required to pay the applicable redemption price to Public Warrant holders if we choose to exercise this redemption right and it will allow us to quickly proceed with a redemption of the Public Warrants if we determine it is in our best interest to do so. As such, we would redeem the Public Warrants in this manner when we believe it is in our best interest to update our capital structure to remove the Public Warrants and pay the redemption price to the Public Warrant holders.

As stated above, we can redeem the Public Warrants when our common stock are trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty with respect to our capital structure and cash position while providing Public Warrant holders with the opportunity to exercise their Public Warrants on a cashless basis for the applicable number of shares. If we choose to redeem the Public Warrants when our common stock are trading at a price below the exercise price of the Public Warrants, this could result in the Public Warrant holders receiving fewer common stock than they would have received if they had chosen to wait to exercise their Public Warrants for common stock if and when such common stock were trading at a price higher than the exercise price of $11.50.

No fractional common stock will be issued upon exercise and only whole Public Warrants will trade. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, we will round down to the nearest whole number of the number of common stock to be issued to the holder.

A holder of a Public Warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such Public Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the Public Warrant agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (as specified by the holder) of our common stock issued and outstanding immediately after giving effect to such exercise.

Anti-dilution adjustments. If the number of outstanding common stock is increased by a capitalization or share dividend payable in common stock, or by a sub-divisions of ordinary shares or other similar event, then, on the effective date of such capitalization or share dividend, sub-divisions or similar event, the number of common stock issuable on exercise of each Public Warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase common stock at a price less than the “historical fair market value” (as defined below) will be deemed a share dividend of a number of common stock equal to the product of (i) the number of common stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for common stock) and (ii) one minus the quotient of (x) the price per common stock paid in such rights offering and (y) the historical fair market value. For these purposes, (i) if the rights offering is for securities convertible into or exercisable for common stock, in determining the price payable for common stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “historical fair market value” means the volume-weighted average price of common stock as reported during the 10 trading day period ending on the trading day prior to the first date on which our common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

If the number of outstanding common stock is decreased by a consolidation, combination, reverse share sub-division or reclassification of common stock or other similar event, then, on the effective date of such consolidation, combination, reverse share sub-division, reclassification or similar event, the number of common stock issuable on exercise of each Public Warrant will be decreased in proportion to such decrease in outstanding common stock.

Whenever the number of common stock purchasable upon the exercise of the Public Warrants is adjusted, as described above, the Public Warrant exercise price will be adjusted by multiplying the Public Warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of common stock purchasable upon the exercise of the Public Warrants

immediately prior to such adjustment and (y) the denominator of which will be the number of common stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding common stock (other than those described above or that solely affects the par value of such common stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our issued and outstanding common stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the Public Warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Public Warrants and in lieu of our common stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of common stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Public Warrants would have received if such holder had exercised their Public Warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of common stock in such a transaction is payable in the form of common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the Public Warrant properly exercises the Public Warrant within thirty days following public disclosure of such transaction, the Public Warrant exercise price will be reduced as specified in the Continental Warrant Agreement based on the Black-Scholes value (as defined in the Continental Warrant Agreement) of the Public Warrant. The purpose of such exercise price reduction is to provide additional value to holders of the Public Warrants when an extraordinary transaction occurs during the exercise period of the Public Warrants pursuant to which the holders of the Public Warrants otherwise do not receive the full potential value of the Public Warrants.

The Public Warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The Continental Warrant Agreement provides that the terms of the Public Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision or correct any mistake, including to conform the provisions of the Continental Warrant Agreement to the description of the terms of the Public Warrants and the Continental Warrant Agreement set forth herein, but requires the approval by the holders of at least 50% of the then outstanding Public Warrants to make any change that adversely affects the interests of the registered holders. You should review a copy of the Continental Warrant Agreement, which is filed as an exhibit to the report to which this exhibit is attached, for a complete description of the terms and conditions applicable to the Public Warrants.

The Public Warrant holders do not have the rights or privileges of holders of ordinary shares and any voting rights until they exercise their Public Warrants and receive common stock. After the issuance of common stock upon exercise of the Public Warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by shareholders.

We have agreed that, subject to applicable law, any action, proceeding or claim against us arising out of or relating in any way to the Continental Warrant Agreement will be brought and enforced in the courts of the State of New York or the U.S. District Court for the Southern District of New York, and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. This provision applies to claims under the Securities Act but does not apply to claims under the Exchange Act or any claim for which the federal district courts of the U.S. of America are the sole and exclusive forum.

Private Placement Warrants

The Private Placement Warrants (including the common stock issuable upon exercise of the Private Placement Warrants) will not be redeemable so long as they are held by Consonance Life Sciences, a Cayman Islands limited liability company, or the Sponsor, or its permitted transferees. The Sponsor, or its permitted transferees, has the option to exercise the Private Placement Warrants on a cashless basis. If the Private Placement Warrants are held by holders other than our Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by us in all redemption scenarios and exercisable by the holders on the same basis as the Public Warrants. Any amendment to the terms of the Private Placement Warrants or any provision of the Continental Warrant Agreement with respect to the Private Placement Warrants will require a vote of holders of at least 50% of the number of the then outstanding Private Placement Warrants.

If holders of the Private Placement Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering his, her or its warrants for that number of common stock equal to the quotient obtained by dividing (x) the product of the number of common stock underlying the warrants, multiplied by the excess of the “historical fair market value” (defined below) over the exercise price of the warrants by (y) the historical fair market value. The “historical fair market value” will mean the average reported closing price of the common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of warrant exercise is sent to the warrant agent. The reason that we have agreed that these warrants will be exercisable on a cashless basis so long as they are held by the Sponsor and permitted transferees is because, as they remained affiliated with us, their ability to sell our securities

in the open market is limited. We expect to have policies in place that restrict insiders from selling our securities except during specific periods of time. Even during such periods of time when insiders will be permitted to sell our securities, an insider cannot trade in our securities if he or she is in possession of material non-public information. Accordingly, unlike public shareholders who could exercise their warrants and sell the common stock received upon such exercise freely in the open market in order to recoup the cost of such exercise, the insiders could be significantly restricted from selling such securities. As a result, we believe that allowing the holders to exercise such warrants on a cashless basis is appropriate.

PIPE Warrants

The PIPE Warrants (including the common stock issuable upon exercise of the PIPE Warrants) are the same in all respects as the Public Warrants as described above under “Public Warrants,” except that the PIPE Warrants were not redeemable prior to August 11, 2022. The PIPE Warrants will be issued pursuant to that certain warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us, dated as of August 11, 2021. A copy of such warrant agreement is filed as an exhibit to the report to which this exhibit is attached.

Anti-Takeover Provisions of Delaware Law and Our Charter Documents

Section 203 of the Delaware General Corporation Law

We are subject to Section 203 of the DGCL, which generally prohibits a publicly held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

•before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, those shares owned (1) by persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

•on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

•In general, Section 203 defines a “business combination” to include the following:

•any merger or consolidation involving the corporation and the interested stockholder;

•any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

•subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

•any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or

•the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or through the corporation.

In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its amended and restated certificate of incorporation or amended and restated bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

Certificate of Incorporation and Bylaws

The Certificate of Incorporation and the Bylaws include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our management team, including the following:

•Board of Directors Vacancies. The Certificate of Incorporation and Bylaws authorize only the board of directors to fill vacant and newly created directorships, unless the board of directors determines by resolution that such vacancies or newly created directorships be filled by the stockholders, or as otherwise provided by law. In addition, the number of directors constituting our board of directors is permitted to be set only by a resolution adopted by the board of directors. These provisions prevent a stockholder from increasing the size of the board of directors and then gaining control of the board of directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our board of directors but promotes continuity of management.

•Classified Board. The Certificate of Incorporation and Bylaws provide that the board of directors is divided into three classes of directors for a period of time following August 11, 2021. Beginning at the 2026 annual meeting of stockholders, all directors will be elected to one-year terms and the board of directors will cease to be classified. The existence of a classified board of directors could discourage a third-party from making a tender offer or otherwise attempting to obtain control of our company as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board of directors.

•Directors Removed Only for Cause. The Certificate of Incorporation provides that stockholders may remove directors only for cause while the board of directors remains classified. Beginning at the 2026 annual meeting of stockholders, directors may be removed with or without cause by the stockholders.

•Supermajority Requirements for Amendments of the Certificate of Incorporation and Bylaws. The Certificate of Incorporation further provides that the affirmative vote of holders of at least two-thirds of the voting power of all of the then outstanding shares of voting stock will be required to amend certain provisions of the Certificate of Incorporation, including provisions relating to the classified board, the size of the board, removal of directors, special meetings, the liability of directors and indemnification. The affirmative vote of holders of at least two-thirds of the voting power of all of the then outstanding shares of voting stock will be required to amend or repeal the Bylaws, although the Bylaws may be amended by a simple majority vote of our board of directors.

•Stockholder Action; Special Meeting of Stockholders. The Certificate of Incorporation and Bylaws provide that special meetings of stockholders may be called only by a majority of the total number of authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the board of directors for adoption), the chairperson of the board of directors, or any chief executive officer, thus prohibiting a stockholder from calling a special meeting. The Certificate of Incorporation provides that the stockholders may not take action by written consent, but may only take action at annual or special meetings of stockholders. As a result, holders of capital stock would not be able to amend the Bylaws or remove directors without holding a meeting of stockholders called in accordance with the Bylaws. These provisions might delay the ability of stockholders to force consideration of a proposal or for stockholders to take any action, including the removal of directors.

•Notice Requirements for Stockholder Proposals and Director Nominations. The Bylaws provide advance notice procedures for stockholders seeking to bring business before the annual meeting of stockholders or to nominate candidates for election as directors at the annual meeting of stockholders. The Bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions might preclude stockholders from bringing matters before the annual meeting of stockholders or from making nominations for directors at the annual meeting of stockholders if the proper procedures are not followed. We expect that these provisions might also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our Company.

•No Cumulative Voting. The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. The Certificate of Incorporation and Bylaws prohibit cumulative voting unless otherwise provided by law.

•Issuance of Undesignated Preferred Stock. Our board of directors will have the authority, without further action by the stockholders, to issue up to 10,000,000 shares of undesignated Preferred Stock with rights and preferences, including voting rights, designated from time to time by our board of directors. The existence of authorized but unissued shares of Preferred Stock will enable our board of directors to render more difficult or to discourage an attempt to obtain control of our company by means of a merger, tender offer, proxy contest, or other means.

Choice of Forum

The Certificate of Incorporation and the Bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action or proceeding asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, or other employees to us or our stockholders; (iii) any action or proceeding asserting a claim against us or any of our current or former directors, officers, or other employees, arising out of or pursuant to any provision of the DGCL, the Certificate of Incorporation or the Bylaws; (iv) any action or proceeding to interpret, apply, enforce, or determine the validity of the Certificate of Incorporation or the Bylaws; (v) any action or proceeding as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; and (vi) any action asserting a claim against us or any of our directors, officers, or other employees governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. These provisions would not apply to suits brought to enforce a duty or liability created by the Exchange Act. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, the Certificate of Incorporation and the Bylaws further provide that the federal district courts of the United States of America will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that such choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than those designated in the exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of the Certificate of Incorporation and the Bylaws.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees and may discourage these types of lawsuits. Furthermore, the enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or bylaws has been challenged in legal proceedings, and it is possible that a court could find these types of provisions to be inapplicable or unenforceable. If a court were to find either exclusive forum provision contained in the Certificate of Incorporation or the Bylaws to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving such action in other jurisdictions, all of which could seriously harm our business.

Corporate Opportunity Doctrine

The DGCL permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. The Certificate of Incorporation, to the extent permitted by the DGCL, renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to a member of our board of directors who is not our employee, or any partner, member, director, stockholder, employee or agent of such member, other than one of our employees. Notwithstanding the foregoing, the Certificate of Incorporation does not renounce our interest in any business opportunity that is expressly offered to a director solely in their capacity as a director.

Exchange Listing

Our common stock and public warrants are listed on the Nasdaq Capital Market under the symbols “SRZN” and “SRZNW,” respectively.

Transfer Agent and Registrar

The transfer agent and registrar for our securities is Continental Stock Transfer & Trust Company. The transfer agent’s address is One State Street Plaza, 30th Floor New York, New York 10004.

The report of the Auditor will include the methodology and calculations used to determine the results, will be delivered to BI and SU at the same time, and will be final [*] after delivery to both Parties, it being understood that BI will have the right during such [*] period to discuss the report with the Auditor. In the event the Parties are not in alignment after such [*] period, either Party may refer this matter for resolution in accordance with the defined dispute resolution procedure set forth in Article 18 (“DISPUTE RESOLUTION”) within [*].

If SU bears any Indirect Tax directly BI shall reimburse SU for such Taxes promptly upon receipt of an invoice.

1.113Withholding Tax.

to SU subject to withholding of Taxes, and if the withholding or deduction of Tax required by Applicable Law with respect to such payment under this Agreement arises or is increased [*], or there is a change, [*], and it is not possible for such withholding to be reduced through the cooperation of the Parties, then such withholding Taxes shall be [*] and any amount payable under this Agreement shall be [*] of withholding Taxes. If BI pays withholding taxes on behalf of SU in such case, SU shall refund BI for any withholding taxes in case SU can recover them after the payment via a tax credit or refund according to national tax provisions or the relevant double tax treaty.4F

SU shall provide on a yearly basis a template to BI outlining the required information for Section 250 of the Internal Revenue Code of 1986, as amended and the applicable Treasury Regulations.

1.115Interest on Late Payments. If BI fails to pay any payment due under this Agreement as provided herein on or before the date such payment is due, then such late payment will bear interest, to the extent permitted by Applicable Law, at an annual rate of [*] which applied on the due date effective for the first date on which payment was delinquent and calculated for the exact number of days in the interest period based on a year of three hundred sixty (360) days (actual/360). If the [*] is no longer published, the Parties will agree upon another internationally recognized rate which has historically been substantially equivalent to the [*] and utilize such rate retroactively to such time as the rate was no longer available.

1.116Record Retention; Audits. SU will maintain compliance records with respect to the Research Program under this Agreement. Such records will be adequate to determine whether the Research Program has been conducted in compliance with this Agreement and Applicable Laws. During the Royalty Term of this Agreement, and up to [*] after its expiration or termination, BI reserves the right to audit SU’s records with respect to the Research Program. At all reasonable times after reasonable notice, SU shall provide BI’s representatives, designees, auditors and regulators, as BI may designate from time to time (“BI Auditors”), access (i) to inspect [*] for the Research Program; (ii) to review and examine [*] performance of the Research Program; (iii) to review and examine [*] performance of the Research Program; and (iv) to perform other audits, including [*], if reasonably required, and reviews necessary to enable BI to comply with Applicable Laws.

Any failure to provide the Indemnifying Party with any such notice will not relieve the Indemnifying Party from any liability that it may have to the Indemnified Party under this Article 16 except to the extent that the ability of the Indemnifying Party to defend such claim is materially prejudiced by the Indemnified Party's failure to give such notice. If the Indemnifying Party assumes such defence, the Indemnified Party will have the right to participate in the defence thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party; provided, that the Indemnified Party will have the right to employ counsel to represent it at the expense of the Indemnifying Party if the Indemnified Party has been advised by its counsel that there are one or more legal defences available to it that are different from or additional to those available to the Indemnifying Party or that there is otherwise a potential conflict between the interests of the Indemnified Party and the Indemnifying Party, in which event the reasonable fees and expenses of such separate counsel will be paid by the Indemnifying Party. If the Indemnifying Party does not assume control of the defence of a Third Party Claim within [*] after the receipt by the Indemnifying Party of the notice required pursuant to this Section 16.3 (“Notification; Assumption of Defence; Cooperation and Assistance”), the Indemnified Party will have the right to defend such claim in such manner as it may deem appropriate at the reasonable cost and expense of the Indemnifying Party.

The Indemnifying Party may not settle or otherwise dispose of any Third Party Claim without the prior written consent of the Indemnified Party unless such settlement includes only the payment of monetary damages (which are fully paid by the Indemnifying Party), does not impose any injunctive or equitable relief upon the Indemnified Party, does not require any admission or acknowledgment of liability or fault of the Indemnified Party and contains an unconditional release of the Indemnified Party in respect of such Third Party Claim. The Indemnified Party may not settle or otherwise dispose of any Third Party Claim for which the Indemnifying Party may be liable for damages under this Agreement without the prior written consent of the Indemnifying Party.

1.134LIMITATION OF LIABILITY. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT OR OTHERWISE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER WITH RESPECT TO ANY SUBJECT MATTER OF THIS AGREEMENT, WHETHER

17.TERM & TERMINATION

1.135Term. This Agreement shall become effective upon the Effective Date and, if not otherwise terminated earlier pursuant to this Article 17 (“TERM & TERMINATION”), shall continue in full force and effect (a) until [*] after the end of the Research Program (the “Selection Period”) if BI has not then selected at least one Target-Specific mono Fzd4 SWAP as a Compound by notice to SU28F or (b) on a country-by-country and Product-by-Product basis until the expiration of the Royalty Term if, prior to or on the end of the Selection Period, BI selects at least one Target-Specific mono Fzd4 SWAP as a Compound .

1.136Termination for Cause. This Agreement may be terminated at any time during the term of this Agreement by either Party:

1.136.1Upon Default by the other Party (the “Defaulting Party”) which Default remains uncured for [*] (the “Default Cure Period”), measured from the date the Defaulting Party receives written notice provided by the other Party (the “Non-Defaulting Party“) of such Default (the “Default Notice“). The Default Notice shall identify the Default, the intent to so terminate this Agreement if the Default remains uncured at the end of the Default Cure Period and the actions or conduct that it considers would be an acceptable cure of such Default. In case the Defaulting Party disputes the Default under this Section 17.2.1, then the issue of whether the Non-Defaulting Party may properly terminate this Agreement on expiration of the Default Cure Period shall be resolved in accordance with Article 18 (“DISPUTE RESOLUTION”). If the Parties agree or an arbitral tribunal determines in an interim arbitral award that the alleged Defaulting Party committed a Default and the Defaulting Party does not subsequently cure such Default within [*] after the date of such agreement or receipt of the interim arbitral award (the “Additional Cure Period”), then such termination shall be effective as of the expiration of the Additional Cure Period and the arbitral tribunal shall be notified accordingly. If either Party disputes whether such Default was so cured, either Party alone may

request the same arbitral tribunal to determine whether it was so cured. The Parties shall cooperate to allow such determination to be made within [*] after such request by either Party. Such dispute resolution process under Article 18 does not suspend any obligations of either Party hereunder, and each Party shall use reasonable efforts to mitigate any damage.

1.153Force Majeure. Neither Party shall be liable or deemed in default for failure to perform any duty or obligation that such Party may have under this Agreement where such failure has been occasioned by any act of God, fire, external strike, inevitable accidents, war, or any other cause outside the reasonable control of that Party, and occurring without its fault or negligence. The Party whose performance has so been interrupted shall give the other Party notice of the interruption and cause thereof, and shall use every reasonable means to resume full performance of this Agreement as soon as possible.

1.154Severability. In the event that any clause or portion thereof in this Agreement is for any reason held to be invalid, illegal or unenforceable, the same shall not affect any other portion of this Agreement, as it is the intent of the Parties that this Agreement shall be construed in such fashion

as to maintain its existence, validity and enforceability to the greatest extent possible. In any such event, this Agreement shall be construed as if such clause of portion thereof had never been contained in this Agreement, and there shall be deemed substituted therefore such provision as will most nearly carry out the intent of the Parties as expressed in this Agreement to the fullest extent permitted by Applicable Law unless doing so would have the effect of materially altering the right and obligations of the Parties.

1.155Waiver. The failure of either Party to require performance by the other Party of any of that other Party’s obligations hereunder shall in no manner affect the right of such Party to enforce the same at a later time. No waiver by any Party of any condition, or of the breach of any provision, term, representation or warranty contained in this Agreement shall be deemed to be or construed as a further or continuing waiver of any such condition or breach, or of any other condition or of the breach of any other provision, term, representation, or warranty hereof. The remedies provided in this Agreement are not exclusive and the Party suffering from a breach or default of this Agreement may pursue all other remedies, both legal and equitable, alternatively or cumulatively.

1.156Anti-Bribery/Anti-Corruption. SU represents and warrants that it, its owners, directors, officers, employees, sub-contractors and agents will act in full compliance with any applicable anti-bribery and anti-corruption laws and regulations, industry and professional codes of practice (including without limitation FCPA, UK Bribery Act, German Criminal Code, and any other international or local legislation, which may become applicable in connection to the Agreement) and will not offer, promise, pay or arrange for payment or giving of a bribe or any benefit, advantage or anything of value to any Public Official, individual, entity or any other third party in exchange for an improper advantage in any form either directly or indirectly. Any violation of this Section 19.7 constitutes a material breach of this Agreement and will allow BI to terminate this Agreement with immediate effect. SU shall indemnify and hold BI harmless for any loss or damage resulting of a breach by SU, its directors, officers, employees, sub-contractors and agents of this Section 19.7 (“Anti-Bribery/Anti-Corruption”).

1.157Notices.

Organization and Business

Note 1. Organization and Business

Organization

Surrozen, Inc., or the Company, formerly known as Consonance-HFW Acquisition Corp., or Consonance, is a clinical stage biotechnology company committed to discovering and developing drug candidates to selectively modulate the Wnt pathway, a critical mediator of tissue repair, in a broad range of organs and tissues, for human diseases. The Company, a Delaware corporation, is located in South San Francisco, California.

Business Combination and Private Investment in Public Entity Financing

Consonance was a blank check company incorporated as a Cayman Islands exempted company on August 21, 2020. It was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses.

On August 11, 2021, Consonance consummated a business combination, or the Business Combination, among Consonance, Perseverance Merger Sub Inc., a subsidiary of Consonance, and Surrozen, Inc., or Legacy Surrozen, a Delaware company incorporated on August 12, 2015. Upon closing of the Business Combination, Consonance became a Delaware corporation and was renamed to Surrozen, Inc., Legacy Surrozen, was renamed to Surrozen Operating, Inc., and Legacy Surrozen continued as a wholly-owned subsidiary of the Company. See Note 3, “Recapitalization” for additional details.

In May 2022, Surrozen Netherlands, B.V. was incorporated and located in Rotterdam, Netherlands as a wholly-owned subsidiary of Surrozen Operating, Inc.

Liquidity

The Company has incurred net losses since inception. The Company has historically financed the operations primarily through private placements of redeemable convertible preferred stock. As of September 30, 2022, the Company had cash, cash equivalents and marketable securities of $78.4 million. As of September 30, 2022, the Company had an accumulated deficit of approximately $177.9 million. The Company expects operating expenses to continue to increase in connection with our ongoing clinical studies and anticipates the need to raise additional capital to continue to execute its long-range business plan.

In October 2022, the Company executed a Collaboration and License Agreement, or CLA, with Boehringer Ingelheim International GmbH, or BI, pursuant to which the Company is eligible to receive a non-refundable upfront payment of $12.5 million (see Note 11). The Company expects to receive approximately $10.5 million of the upfront payment in the fourth quarter of 2022 and the remaining $2.0 million during the first six months of 2023.

Management believes that the existing cash, cash equivalents, and marketable securities, plus the gross cash proceeds of $12.5 million that will be received pertaining to the CLA, before deducting the fees of $1.3 million to be paid to Stanford and The Regents of the University of California (see Note 11), are sufficient for the Company to continue operating activities for at least the next 12 months from the date of issuance of its unaudited condensed consolidated financial statements. However, if the Company’s anticipated cash burn is greater than anticipated, the Company could use its capital resources sooner than expected which may result in the need to reduce future planned expenditures and/or raise additional capital to continue to fund the operations.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The Company’s unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP, and pursuant to the regulations of the U.S. Securities and Exchange Commission, or SEC. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted and accordingly, the condensed consolidated balance sheet as of December 31, 2021 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of the Company’s consolidated

financial statements. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ended December 31, 2022 or for any other interim period or future year.

The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated.

The Business Combination discussed in Note 1 was accounted for as a reverse recapitalization with Legacy Surrozen as the accounting acquirer and Consonance as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the unaudited condensed consolidated financial statements represents the accounts of Legacy Surrozen at their historical cost as if Legacy Surrozen is the predecessor to the Company. The unaudited condensed consolidated financial statements following the closing of the Business Combination reflect the results of the combined entity’s operations. All issued and outstanding common stock, redeemable convertible preferred stock and stock awards of Legacy Surrozen and per share amounts contained in the unaudited condensed consolidated financial statements for the periods presented prior to the closing of the Business Combination on August 11, 2021 have been retroactively restated to reflect the exchange ratio established in the Business Combination. See Note 3, “Recapitalization” for additional details.

The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 28, 2022.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions made in the accompanying unaudited condensed consolidated financial statements include, but are not limited to, certain accrued expenses for research and development activities, the fair value of common stock prior to the Business Combination, stock-based compensation expense and income taxes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could materially differ from those estimates.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to significant concentration of credit risk, consist of cash, cash equivalents and marketable securities. The Company's cash is held by one financial institution that management believes is creditworthy. Such deposits held with the financial institution may at times exceed federally insured limits, however, its exposure to credit risk in the event of default by the financial institution is limited to the extent of amounts recorded on the unaudited condensed consolidated balance sheets. The Company performs evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company's policy is to invest cash in institutional money market funds and marketable securities with high credit quality to limit the amount of credit exposure. The Company currently maintains a portfolio of cash equivalents and marketable securities in a variety of securities, including money market funds, U.S. government bonds, commercial paper and corporate debt securities. The Company has not experienced any realized losses on its cash equivalents and marketable securities.

Marketable Securities

The Company invests its excess cash in U.S. government bonds, commercial paper and corporate debt securities. All marketable securities have been classified as available-for-sale and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. The Company does not buy or hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity and return. From time to time, the Company may sell certain securities, but the objectives are generally not to generate profits on short-term differences in price.

Short-term marketable securities have maturities less than or equal to one year as of the balance sheet date. Long-term marketable securities have maturities greater than one year as of the balance sheet date. These marketable securities are carried at estimated fair value with unrealized holding gains or losses included in accumulated other comprehensive loss in stockholders’ equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Interest income is recognized in the unaudited condensed consolidated statements of operations and comprehensive loss when earned.

The Company periodically evaluates its available-for-sale marketable securities for impairment. When the fair value of a marketable security is below its amortized cost basis, the amortized cost is reduced to its fair value if it is more likely than not that the Company is required to sell the impaired security before recovery of its amortized cost, or the Company has the intention to sell the security. If neither of these conditions are met, the Company determines whether the impairment is due to credit losses by comparing the present value of the expected cash flows of the security with its amortized cost basis. The amount of impairment recognized is limited to the excess of the amortized cost basis over the fair value of the security. An allowance for credit losses for the excess of amortized cost basis over the expected cash flows, if any, is recorded in other income (expense), net on the unaudited condensed consolidated statements of operations. Impairment losses that are not credit-related are included in accumulated other comprehensive loss in stockholders’ equity.

Warrant Liabilities

The Company's Public Warrants, Private Placement Warrants and PIPE Warrants were classified as liabilities (see Note 9). At the end of each reporting period, any changes in fair value during the period are recognized in other income, net within the unaudited condensed consolidated statements of operations and comprehensive loss. The Company will continue to adjust the warrant liabilities for changes in the fair value until the earlier of a) the exercise or expiration of the warrants or b) the redemption of the warrants, at which time such warrants will be reclassified to additional paid-in capital.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss attributable to common stock by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive securities. Since the Company was in a loss position for the periods presented, basic net loss per share is the same as diluted net loss per share as the effects of potentially dilutive securities are antidilutive. The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share of common stock as of the periods presented because including them would have been antidilutive (in thousands):

	September 30,
	2022		2021

Recapitalization Note [Abstract]

Recapitalization

Note 3. Recapitalization

On August 11, 2021, Consonance consummated the Business Combination (see Note 1). Immediately after the consummation of the Business Combination, certain investors subscribed for and purchased an aggregate of 12.0 million units, each consisting of one share of the Company’s common stock and one-third of one redeemable warrant, for a purchase price of $10.00 per unit through a private investment in public entity financing, or PIPE Financing. In connection with the Business Combination and PIPE Financing, Legacy Surrozen received the aggregate cash consideration of $128.8 million, after deducting the transaction fees incurred by Consonance. The cash consideration was comprised of $8.6 million in proceeds from issuance of common stock upon the closing of the Business Combination and $120.2 million in proceeds from the PIPE Financing. The Company incurred transaction costs of $6.3 million, consisting of legal, accounting and other professional services directly related to the Business Combination, $0.4 million of which were allocated to the warrant liabilities assumed and recognized as other expenses when incurred. The remaining $5.9 million were recorded as a reduction of additional paid-in capital in the unaudited condensed consolidated balance sheet. Legacy Surrozen was deemed the accounting acquirer in the Business Combination and the Business Combination was accounted for as a reverse recapitalization based on the following predominant factors:

•Legacy Surrozen’s stockholders have the greatest voting interest in the Company;

•The Company’s board and senior management are primarily composed of individuals associated with Legacy Surrozen; and

•Legacy Surrozen is the larger entity based on historical operating activity and has the larger employee base at the time of the Business Combination.

Accordingly, for accounting purposes, the reverse recapitalization was treated as the equivalent of Legacy Surrozen issuing stock for the net assets of Consonance, accompanied by a recapitalization. The net assets of Consonance are stated at historical cost, with no goodwill or other intangible assets recorded.

Pursuant to the business combination agreement, upon the closing of the Business Combination, (i) each share of redeemable convertible preferred stock of Legacy Surrozen (on an as converted to common stock basis) and each share of common stock of Legacy Surrozen, whether vested or unvested, was converted into 0.175648535 shares of the Company’s common stock and (ii) each outstanding option to purchase common stock of Legacy Surrozen was converted into an option to purchase shares of the Company’s common stock based on an exchange ratio of 0.175648535, or the Exchange Ratio, with corresponding adjustments to the exercise price. All issued and outstanding common stock, preferred stock and stock awards of Legacy Surrozen and corresponding capital amounts contained in the unaudited condensed consolidated financial statements for the periods presented prior to the closing of the Business Combination have been retroactively restated to reflect the conversion.

(1)Money market funds are included in cash and cash equivalents on the unaudited condensed consolidated balance sheets as of September 30, 2022 and December 31, 2021.

(2)See the definition and discussion of Public Warrants, Private Placement Warrants and PIPE Warrants in Note 9.

There were no changes to the valuation methods utilized and there were no transfers of financial instruments between Level 1, Level 2, and Level 3 during the nine months ended September 30, 2022.

Corporate bonds, commercial paper, foreign bonds and government bonds are classified as Level 2 as they were valued based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets.

The Public Warrants are classified as Level 1 due to the use of an observable market quote in an active market. The Private Placement Warrants and PIPE Warrants are classified as Level 2 due to the use of observable market data for identical or similar liabilities. The fair value of each Private Placement Warrant and PIPE Warrant was determined to be consistent with that of a Public Warrant because the Private Placement Warrants and PIPE Warrants are also subject to the make-whole redemption feature, which allows the Company to redeem both types of warrants on similar terms when the stock price is in the range of $10 to $18 per share.

The following table indicates the length of the time that individual securities have been in a continuous unrealized loss position as of September 30, 2022 (dollars in thousands):

Corporate bonds		7	$	16,946	$	60
Government bonds		3		17,695		364
Total		10	$	34,641	$	424

As of September 30, 2022 and December 31, 2021, all short-term marketable securities had maturities of one year or less. There have been no significant realized gains or losses on the short-term and long-term marketable securities during the three and nine months ended September 30, 2022 and 2021. The Company periodically reviews the available-for-sale investments for other-than-temporary impairment loss. All investments with unrealized losses have been in a loss position for less than 12 months. The Company determined that the unrealized loss was primarily attributed to changes in current market interest rates and not to credit quality. The Company does not intend to sell the marketable securities that are in an unrealized loss position, nor is it more likely than not that the Company will be required to sell the marketable securities before the recovery of the amortized cost basis, which may be at maturity. As a result, the Company did not recognize any other-than-temporary impairment losses as of September 30, 2022.

In March 2016, the Company entered into a license agreement with Stanford University, or the 2016 Stanford Agreement, which was amended in July 2016, October 2016 and January 2021, pursuant to which the Company obtained from Stanford a worldwide, exclusive, sublicensable license under certain patents, rights, or licensed patents and technology related to its engineered Wnt surrogate molecules to make, use, import, offer to sell and sell products that are claimed by the licensed patents or that use or incorporate such technology, or licensed products, for the treatment, diagnosis and prevention of human and veterinary diseases. The Company agreed to pay Stanford an aggregate of up to $0.9 million for the achievement of specified development and regulatory milestones, and an aggregate of up to $5.0 million for achievement of specified sales milestones. Stanford is also entitled to receive royalties from the Company equal to a very low single digit percentage of the Company’s and its sublicensees’ net sales of licensed products that are covered by a valid claim of a licensed patent. Additionally, the Company agreed to pay Stanford a low double-digit percentage of non-royalty sublicense consideration received by the Company in connection with any sublicense granted to a third-party and, if the Company is acquired, a one-time change of control fee in the low six figures.

In June 2018, the Company entered into another license agreement with Stanford, or the 2018 Stanford Agreement, pursuant to which the Company obtained from Stanford a worldwide, exclusive, sublicensable license under certain patent rights related to its surrogate R-spondin proteins, or the licensed patents, to make, use, import, offer to sell and sell products that are claimed by the licensed patents, or licensed products, for the treatment, diagnosis and prevention of human and veterinary diseases, or the exclusive field. Additionally, Stanford granted the Company a worldwide, non-exclusive, sublicensable license under the licensed patents to make and use licensed products for research and development purposes in furtherance of the exclusive field and a worldwide, non-exclusive license to make, use and import, but not to offer to sell or sell, licensed products in any other field of use. The Company agreed to pay Stanford an aggregate of up to $0.4 million for the achievement of specified development and regulatory milestones. Stanford is also entitled to receive royalties from the Company equal to a sub-single digit percentage of the Company’s and its sublicensees’ net sales of licensed products. Additionally, Stanford is entitled to receive a one-time payment in the low six figures for each sublicense of the licensed patents that the Company grants to a third party and, if the Company is acquired, a one-time nominal change of control fee.

For the three and nine months ended September 30, 2022, the Company incurred de minimis and $0.1 million research and development expenses under the Stanford agreements.

UCSF License and Option Agreements

In September and October 2016, the Company entered into two separate license and option agreements with The Regents of the University of California, or the UCSF Agreements, pursuant to which the Company obtained exclusive licenses from UCSF for internal research and antibody discovery purposes and an option to negotiate with UCSF to obtain an exclusive license under UCSF’s rights in the applicable library to make, use, sell, offer for sale and import products incorporating antibodies identified or resulting from the Company’s use of such library, or licensed products.

In January 2020, the Company amended and restated the UCSF Agreements to provide non-exclusive licenses to make and use a certain human Fab naïve phage display library and to make and use a certain phage display llama VHH single domain antibody library for internal research and antibody discovery purposes and an option to negotiate with UCSF to obtain a non-exclusive commercial license under UCSF’s rights in the applicable library to make, use, sell, offer for sale and import products incorporating antibodies identified or resulting from the Company’s use of such library, or licensed products.

In March 2022, the Company exercised the option under the UCSF Agreements and entered into a non-exclusive commercial license agreement to make and use licensed products derived from the phage display llama VHH single domain antibody library. Under the commercial license agreement, the Company paid UCSF a nominal license issue fee and agreed to pay a nominal annual license maintenance fee, five- to six-digit payments per licensed product upon achievement of a regulatory milestone, nominal minimum annual royalties, and earned royalties equal to a sub-single digit percentage of the Company’s and the Company’s sublicensees’ net sales of licensed products.

The Company agreed to pay Distributed Bio an annual fee in the low six figures after the first three years. Additionally, the Company agreed to pay Distributed Bio an aggregate of $5.9 million for each licensed product that achieves specified development, regulatory and commercial milestones and royalties equal to a very low single digit percentage of the Company’s and its sublicensees’ net sales of licensed products. The Company’s obligation to pay royalties will end for each licensed product ten years after its first commercial sale.

For the three and nine months ended September 30, 2022, the Company incurred $0.1 million research and development expenses under the Distributed Bio Agreement as the Company achieved a milestone with regard to the initiation of the Phase 1 clinical trial for SZN-1326 in May 2022.

As contemplated by the Equity Purchase Agreement, and so long as the closing price of the Company’s common stock exceeds $1.00 per share, the Company may direct Lincoln Park, at its sole discretion, to purchase up to 30,000 shares of its common stock, or the Regular Purchase Share Limit, on any business day at a purchase price per share equal to the lower of: (i) the lowest price of the Company’s common stock on the applicable purchase date and (ii) the average of the 3 lowest closing prices of the Company’s common stock during the 10 consecutive business days preceding such purchase date. The Regular Purchase Share Limit may be increased to up to 35,000 shares and 40,000 shares if the closing price of the Company’s common stock is not below $10.00 per share and $12.00 per share, respectively. Any single purchase of the Company’s common stock shall not exceed $3.5 million.

The Company may also direct Lincoln Park to purchase additional shares no less than the Regular Purchase Share Limit and no greater than 500,000 shares at a purchase price per share equal to 96% of the lower of (i) the closing price of the Company’s common stock on the purchase date and (ii) the volume weighted average price of the Company’s common stock on the purchase date.

Common Stock Warrants

Note 9. Common Stock Warrants

In connection with the Business Combination, Legacy Surrozen, as the accounting acquirer, was deemed to assume warrants held by Consonance’s stockholders, or the Public Warrants, and warrants held by Consonance's sponsor, or the Private Placement Warrants. In addition, in the PIPE Financing, certain investors subscribed for and purchased an aggregate of 12.0 million units, each consisting of one share of the Company’s common stock and one-third of one redeemable warrant, or PIPE Warrants. All of these warrants were outstanding as of September 30, 2022. The following table sets forth the common stock warrants outstanding as of September 30, 2022 (in thousands, except exercise price per warrant):

Type	Classification	Expiration Date	Exercise Price per Warrant		Number of Warrants		Fair Value
Public Warrants	Liability	August 12, 2026	$	11.50		3,067	$	566
Private Placement Warrants	Liability	August 12, 2026		11.50		145		27
PIPE Warrants	Liability	August 12, 2026		11.50		4,007		739
Total						7,219	$	1,332

Public Warrants

Each whole Public Warrant entitles the holder to purchase one share of the Company’s common stock at a price of $11.50 per share, at any time commencing on November 23, 2021 and terminating at the earlier of August 12, 2026 or upon redemption or liquidation. The exercise price and number of shares issuable upon exercise of the Public Warrants may be adjusted in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. The Company would not be obligated to deliver any shares of common stock pursuant to the exercise of a Public Warrant and would have no obligation to settle such Public Warrant exercise unless a registration statement under the Securities Act with respect to the common stock underlying the Public Warrants is then effective. The registration statement on Form S-1 to register for resale under the Securities Act of 1933, as amended, was effective in November 2021. The Company shall use its efforts to maintain the effectiveness of the registration statement until the expiration or redemption of the Public Warrants. If the Company fails to have maintained an effective registration statement, the Public Warrant holders have the right to exercise the Public Warrants on a cashless basis until such time as there is an effective registration statement.

The Company may redeem the outstanding Public Warrants at a price of $0.01 per warrant if the closing price of common stock equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction). Additionally, the Company may redeem the outstanding Public Warrants at a price of $0.10 per warrant if the closing price of common stock equals or exceeds $10.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction). Notice of redemption shall be mailed to the Public Warrant holders no less than 30 days prior to the redemption date, or the Redemption Period. If the closing price of common stock equals or exceeds $10.00 per share and is less than $18.00 per share, during the Redemption Period, the Public Warrant holders may elect to exercise their Public Warrants on a cashless basis based on a make-whole table.

In no event will the Company be required to net cash settle the Public Warrants. The Public Warrant holders do not have the rights or privileges of common stockholders and any voting rights until they exercise their Public Warrants and receive common stock.

Private Placement Warrants

The Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants, except that so long as they are held by Consonance's sponsor or any of its permitted transferees, the Private Placement Warrants: (i) may be exercised for cash or on a cashless basis, (ii) may not be transferred, assigned or sold until 30 days after the completion of the Business Combination, (iii) shall not be redeemable by the Company if the closing price of common stock equals or exceeds $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction) and (iv) shall only be redeemable if the closing price of common stock is less than $18.00 per share (as adjusted for share sub-divisions, share capitalizations, reorganizations, recapitalizations and similar transaction). If the Private Placement Warrants are held by holders other than Consonance's sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the Public Warrants.

PIPE Warrants

Each whole PIPE Warrant entitles the holder to purchase one share of the Company’s common stock at a price of $11.50 per share, at any time commencing on November 23, 2021 and terminating on August 12, 2026. The PIPE Warrants are the same in all respects as the Public Warrants except that the PIPE Warrants are not redeemable before August 12, 2022.

Classification

The Public Warrants, Private Placement Warrants and PIPE Warrants are not considered indexed to the Company’s common stock as certain provisions of the warrant agreements could change the settlement amount of these warrants. As a result, they were classified as liabilities and recorded at fair value with subsequent change in their respective fair value recognized in the other income (expense), net within the unaudited condensed consolidated statements of operations and comprehensive loss at each reporting date. See Note 4 for the discussion of warrant valuations.

Stock Based Compensation Plan

Note 10. Stock-Based Compensation Plan

The Company maintains the 2021 Equity Incentive Plan, or the 2021 Plan, which provides for the granting of stock awards to employees, directors and consultants. Options granted under the 2021 Plan may be either incentive stock options, or ISOs, or nonqualified stock options, or NSOs. Options granted under the 2021 Plan expire no later than 10 years from the date of grant. Options under the 2021 Plan generally vest 25% upon one year of continued service to the Company, with the remainder in monthly increments over three additional years. As of September 30, 2022, there were 4.5 million shares of common stock available for issuance under the 2021 Plan.

The Company adopted the 2021 Employee Stock Purchase Plan, or the ESPP, in August 2021. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to plan limitations. An offering period under the ESPP consists of four six-month purchase periods, unless otherwise determined by the Company. The eligible employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the purchase day. As of September 30, 2022, there were 0.9 million shares of common stock available for issuance under the ESPP. No shares have been issued under the ESPP as of September 30, 2022.

Stock-based compensation expense under the ESPP is measured at the beginning of the offering period using the Black-Scholes option-pricing model and recognized on a straight-line basis over the offering period.

Stock Options

A summary of stock option activity is set forth below:

	Options outstanding
						Weighted
				Weighted		Average		Aggregate

Exercisable – September 30, 2022		1,194			4.17		7.47		574

The aggregate intrinsic values of options outstanding and exercisable are the differences between the exercise price of the options and the fair value of the Company’s common stock at September 30, 2022.

During the nine months ended September 30, 2022, the Company granted options with a weighted-average grant-date fair value of $2.31 per share.

The fair value of options is estimated at the grant date using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Option Exchange

In October 2022, the Company’s Compensation Committee authorized and approved a stock option exchange whereby certain outstanding stock options held by current employees were exchanged for stock options on a one-for-one basis with an exercise price at the current market price on the date of the exchange. As a result of this exchange, 1.3 million outstanding stock options, with a weighted average exercise price of $8.81 per share, were exchanged for 1.3 million new stock options under the 2021 Plan with an exercise price of $2.16 per share. The vesting terms and expiration dates of the new stock options remain unchanged from the original stock options.

Collaboration and License Agreement

In October 2022, the Company executed the CLA with BI to research, develop and commercialize Fzd4 bi-specific antibodies designed using the Company’s SWAP™ technology, including SZN-413. BI and the Company will conduct partnership research focused on SZN-413 during a one-year period, which BI has the right to extend by up to 6 months. After completion of the partnership research, BI will have an exclusive, royalty-bearing, worldwide, sublicensable license to be responsible for all further research, preclinical and clinical development, manufacturing, regulatory approvals and commercialization of the licensed products at its expense.

Under the terms of the CLA, the Company will receive a non-refundable upfront payment of $12.5 million and will be eligible to receive success-based milestone payments up to $587 million plus mid-single digit to low-double digit royalties on net sales of the licensed products should any reach commercialization. In relation to the CLA, the Company was obligated to pay a fee of $1.2 million and $0.1 million to Stanford University and The Regents of the University of California, respectively.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The Company’s unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP, and pursuant to the regulations of the U.S. Securities and Exchange Commission, or SEC. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted and accordingly, the condensed consolidated balance sheet as of December 31, 2021 has been derived from the Company’s audited consolidated financial statements at that date but does not include all of the information required by GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of the Company’s consolidated

financial statements. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ended December 31, 2022 or for any other interim period or future year.

The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions and balances have been eliminated.

The Business Combination discussed in Note 1 was accounted for as a reverse recapitalization with Legacy Surrozen as the accounting acquirer and Consonance as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the unaudited condensed consolidated financial statements represents the accounts of Legacy Surrozen at their historical cost as if Legacy Surrozen is the predecessor to the Company. The unaudited condensed consolidated financial statements following the closing of the Business Combination reflect the results of the combined entity’s operations. All issued and outstanding common stock, redeemable convertible preferred stock and stock awards of Legacy Surrozen and per share amounts contained in the unaudited condensed consolidated financial statements for the periods presented prior to the closing of the Business Combination on August 11, 2021 have been retroactively restated to reflect the exchange ratio established in the Business Combination. See Note 3, “Recapitalization” for additional details.

The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 28, 2022.

Use of Estimates

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions made in the accompanying unaudited condensed consolidated financial statements include, but are not limited to, certain accrued expenses for research and development activities, the fair value of common stock prior to the Business Combination, stock-based compensation expense and income taxes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could materially differ from those estimates.

Concentration of Credit Risk

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to significant concentration of credit risk, consist of cash, cash equivalents and marketable securities. The Company's cash is held by one financial institution that management believes is creditworthy. Such deposits held with the financial institution may at times exceed federally insured limits, however, its exposure to credit risk in the event of default by the financial institution is limited to the extent of amounts recorded on the unaudited condensed consolidated balance sheets. The Company performs evaluations of the relative credit standing of these financial institutions to limit the amount of credit exposure. The Company's policy is to invest cash in institutional money market funds and marketable securities with high credit quality to limit the amount of credit exposure. The Company currently maintains a portfolio of cash equivalents and marketable securities in a variety of securities, including money market funds, U.S. government bonds, commercial paper and corporate debt securities. The Company has not experienced any realized losses on its cash equivalents and marketable securities.

Marketable Securities

Marketable Securities

The Company invests its excess cash in U.S. government bonds, commercial paper and corporate debt securities. All marketable securities have been classified as available-for-sale and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. The Company does not buy or hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity and return. From time to time, the Company may sell certain securities, but the objectives are generally not to generate profits on short-term differences in price.

Short-term marketable securities have maturities less than or equal to one year as of the balance sheet date. Long-term marketable securities have maturities greater than one year as of the balance sheet date. These marketable securities are carried at estimated fair value with unrealized holding gains or losses included in accumulated other comprehensive loss in stockholders’ equity until realized. Gains and losses on marketable security transactions are reported on the specific-identification method. Interest income is recognized in the unaudited condensed consolidated statements of operations and comprehensive loss when earned.

The Company periodically evaluates its available-for-sale marketable securities for impairment. When the fair value of a marketable security is below its amortized cost basis, the amortized cost is reduced to its fair value if it is more likely than not that the Company is required to sell the impaired security before recovery of its amortized cost, or the Company has the intention to sell the security. If neither of these conditions are met, the Company determines whether the impairment is due to credit losses by comparing the present value of the expected cash flows of the security with its amortized cost basis. The amount of impairment recognized is limited to the excess of the amortized cost basis over the fair value of the security. An allowance for credit losses for the excess of amortized cost basis over the expected cash flows, if any, is recorded in other income (expense), net on the unaudited condensed consolidated statements of operations. Impairment losses that are not credit-related are included in accumulated other comprehensive loss in stockholders’ equity.

Warrant Liabilities

Warrant Liabilities

The Company's Public Warrants, Private Placement Warrants and PIPE Warrants were classified as liabilities (see Note 9). At the end of each reporting period, any changes in fair value during the period are recognized in other income, net within the unaudited condensed consolidated statements of operations and comprehensive loss. The Company will continue to adjust the warrant liabilities for changes in the fair value until the earlier of a) the exercise or expiration of the warrants or b) the redemption of the warrants, at which time such warrants will be reclassified to additional paid-in capital.

Net Loss Per Share

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss attributable to common stock by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive securities. Since the Company was in a loss position for the periods presented, basic net loss per share is the same as diluted net loss per share as the effects of potentially dilutive securities are antidilutive. The following table presents the potential shares of common stock outstanding that were excluded from the computation of diluted net loss per share of common stock as of the periods presented because including them would have been antidilutive (in thousands):

	September 30,
	2022		2021
