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 preclinical 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.

Liquidity

The Company has incurred net operating losses each period since inception. During the three months ended March 31, 2022 and 2021, the Company incurred a net loss of $7.9 million and $13.0 million, respectively. During the three months ended March 31, 2022 and 2021, the Company used $18.4 million and $10.3 million of cash in operations. As of March 31, 2022, the Company had an accumulated deficit of approximately $150.6 million. The Company expects operating losses to continue in the foreseeable future because of additional costs and expenses related to the research and development activities. As of March 31, 2022, the Company had cash, cash equivalents and marketable securities of $104.3 million.

In February 2022, the Company entered into a purchase agreement, or the Equity Purchase Agreement, and a registration rights agreement with Lincoln Park Capital Fund, LLC, or Lincoln Park, pursuant to which Lincoln Park is obligated to purchase up to $50.0 million of the Company’s common stock from time to time at the Company’s sole discretion over a 36-month period commencing on April 27, 2022 (see Note 8).

Management believes that the existing cash, cash equivalents, and marketable securities 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 financial statements. The results of operations for the three months ended March 31, 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 for any other future year.

The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiary. 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 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 period. Significant estimates and assumptions made in the accompanying unaudited condensed consolidated financial statements include, but are not limited to, certain accruals 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, foreign bonds, commercial paper and corporate debt securities. The Company has not experienced any losses on its cash equivalents and marketable securities.

Marketable Securities

The Company invests its excess cash in marketable U.S. government bonds, foreign 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 and 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, 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 basis, 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 over the fair value of the security. An allowance for credit losses for the excess of amortized cost over the expected cash flows is recorded in other income 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 8). At the end of each reporting period, any changes in fair value during the period are recognized in other income 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 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):

	2022		2021

Options outstanding		3,336		1,537

Unvested common stock subject to repurchase		53		115
Warrants to purchase common stock		1,804		—
Total		5,336		1,771

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.

Money market funds are included in cash and cash equivalents on the unaudited condensed consolidated balance sheets as of March 31, 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 three months ended March 31, 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.

As of March 31, 2022 and December 31, 2021, all short-term marketable securities had maturities of one year or less. All long-term marketable securities as of March 31, 2022 and December 31, 2021 had maturities of greater than one year but less than two years. There have been no significant realized gains or losses on the short-term and long-term marketable securities during the three months ended March 31, 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 March 31, 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, the Company agreed to pay Stanford 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 months ended March 31, 2022 and 2021, the Company incurred de minimis research and development expenses under the Stanford agreements. No milestones have been achieved as of March 31, 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 months ended March 31, 2022 and 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 March 31, 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, 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 months ended March 31, 2022 and 2021, the Company incurred de minimis research and development expenses under the Distributed Bio Agreement. No milestones have been achieved during the three months ended March 31, 2022.

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.

In January 2020, the Company entered into a lease agreement for a term of 18 months for approximately 6,478 square feet of office space. This office space lease, which commenced in June 2020, is classified as an operating lease and the rent payments escalate after 14 months. In September 2021, the Company amended the lease to extend the lease term until June 2022.

The operating lease expense for the three months ended March 31, 2022 and 2021 was $0.5 million, respectively.

Aggregate future minimum rental payments under the operating leases as of March 31, 2022, were as follows (in thousands):


Remaining nine months ending December 31, 2022	$	2,014
Year ending December 31, 2023		2,596

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. The Company incurred the costs of $0.5 million, primarily consisting of the commitment shares issued and the legal fees related to the Equity Purchase Agreement, that were recorded as deferred charges included in other assets on the unaudited condensed consolidated balance sheet and will be recognized against the proceeds from the sale of common stock under the Equity Purchase Agreement. 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 the additional commitment fee of $0.1 million 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 weighted average price of the Company’s common stock on the purchase date.

As of March 31, 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 March 31, 2022. The following table sets forth the common stock warrants outstanding as of March 31, 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	$	767
Private Placement Warrants	Liability	August 12, 2026		11.50		145		36
PIPE Warrants	Liability	August 12, 2026		11.50		4,007		1,001
Total						7,219	$	1,804

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 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 March 31, 2022, there were 5.0 million shares of common stock available for issuance under the 2021 Plan.

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 plan to initiate a Phase 1 clinical trial in the third 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. Furthermore, we plan to initiate a Phase 1 clinical trial in the third quarter of 2022 for SZN-043, our candidate in development for severe alcoholic hepatitis, or AH. We expect to nominate additional lead candidates and advance them into the clinic in 2023 and beyond. In January 2022, we nominated SZN-413, as a development candidate for the treatment of retinal vascular -associated diseases.

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. In our most advanced research programs, we are developing potential therapeutics for ocular diseases such as retinal vascular diseases. Genetic

studies in the literature have identified that the Wnt signaling pathway is critical for maintenance of healthy retinal blood vessels. We have shown that activation of Wnt-pathway signaling can potentially reverse vascular damage through a mechanism that is distinct from the mechanisms of currently approved therapeutics that target angiogenesis. We also have identified the potential for regeneration of retinal pigment epithelium, or RPE, an important cell type in the retina. RPE cells are required for maintenance and viability of photoreceptors and as such are a potential target for the treatment of dry AMD. We are also assessing the potential to drive tissue repair in conditions such as hearing loss and diseases resulting in tissue injury to organs including the cornea, lacrimal gland, lung and kidney.

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 intellectual property portfolio, and providing general and administrative support for these operations. We have incurred net losses since inception. During the three months ended March 31, 2022 and 2021, we incurred net losses of $7.9 million and $13.0 million. As of March 31, 2022, we had an accumulated deficit of $150.6 million and cash, cash equivalents and marketable securities of $104.3 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 planned 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 rapidly, 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.

UCSF Commercial License Agreement

In March 2022, we exercised the option under the amended and restated license and option agreements with The Regents of the University of California executed in January 2020 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, we 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 our and our sublicensees’ net sales of licensed products.

We have not generated any revenue from the sale of our products, and we do not expect to generate any revenue unless and until we obtain regulatory clearance or approval of, and commercialize, our product candidates.

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 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 initiate 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 and SZN-043 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;

•

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 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 future collaborators, 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;

•

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, and other administrative functions. General and administrative expenses also include legal fees, professional fees paid for accounting, auditing, consulting, tax, 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 those of the 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

Other income consists of the gain on the change in fair value of warrant liabilities.

	Three Months Ended March 31,				$			%
	2022		2021		Change			Change
External expenses(1)	$	3,366	$	4,314	$	(948	)		-22	%

Total research and development expenses	$	9,371	$	8,601	$	770			9	%

(1) In future periods when clinical trial expenses are incurred, external expenses will be broken out between our clinical programs and preclinical programs.

The increase of $0.8 million, or 9%, in research and development expenses for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, is due in part to the $1.2 million increase in personnel-related expenses as a result of a higher headcount and options granted to our employees and the increase of $0.5 million in facilities and other expenses is attributable to the increase in headcount and corporate insurance, offset by the $0.3 million decrease in external expenses primarily due to the completion of manufacturing drug substance for our SZN-1326 and SZN-043 programs.

General and Administrative Expenses

The increase of $0.7 million, or 16%, in general and administrative expenses for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, is primarily attributable to the $1.3 million increase in personnel-related expenses due to an increase in headcount and options granted to our employees and the $0.5 million increase in corporate insurance, offset by the $1.1 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 $40,000, or 444%, in interest income for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, is primarily due to the increase in investments in money market funds and marketable securities.

Other Income

The increase of $6.5 million in other income for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, is related to the gain on the change in fair value of warrant liabilities.

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 sale of our redeemable convertible preferred stock. As of March 31, 2022, we had cash, cash equivalents and marketable securities of $104.3 million and an accumulated deficit of $150.6 million.

In February 2022, we entered into a purchase agreement and a registration rights agreement with Lincoln Park, 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.

We believe, based on our current operating plan, that our existing cash, cash equivalents, and marketable securities 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.

Future Funding Requirements

To date, we have not generated any revenue. We do not expect to generate any meaningful revenue unless and until we obtain regulatory approval and commercialize SZN-1326 and SZN-043 or any future product candidates, and we do not know when, or if, that will occur. We will continue to require substantial additional capital to develop SZN-1326 and SZN-043 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 SZN-1326 and SZN-043 into 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 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 studies, in particular our current ongoing preclinical studies of SZN-1326 and SZN-043;

•

the outcome, costs, and timing involved in, obtaining regulatory approvals for our lead product candidate 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 and SZN-043 and any future 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 to Lincoln Park under the Equity Purchase Agreement, 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 SZN-1326 and SZN-043 and any 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):


	Three Months Ended March 31,
	2022			2021

Net cash used in operating activities	$	(18,374	)	$	(10,332	)
Net cash used in investing activities		(412	)		(1,442	)
Net cash provided by financing activities		—			196
Net decrease in cash, cash equivalents and restricted cash	$	(18,786	)	$	(11,578	)

Cash Used in Operating Activities

Cash used in operating activities of $18.4 million for the three months ended March 31, 2022 was primarily due to the use of funds in our operations and the resulting net loss of $7.9 million, a net change of $5.9 million in our net operating assets and liabilities and $4.6 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 used in operating activities of $10.3 million for the three months ended March 31, 2021 was primarily due to the use of funds in our operations and the resulting net loss of $13.0 million, partially offset by $1.3 million in

non-cash charges and a net change of $1.4 million in our net operating assets and liabilities. 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 Used in Investing Activities

Cash used in investing activities of $0.4 million for the three months ended March 31, 2022 was for the purchase of laboratory and computer equipment. Cash used in investing activities of $1.4 million for the three months ended March 31, 2021 consisted primarily of $1.1 million of cash used for the purchase of marketable securities and $0.3 million of cash used for the purchase of lab equipment.

Cash Provided by Financing Activities

Cash provided by financing activities of $0.2 million for the three months ended March 31, 2021 consisted primarily of the proceeds from the exercise of options.

Contractual Obligations and Commitments

Our contractual obligations as of March 31, 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 U.S. 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 three months ended March 31, 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 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 $1.07 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 $1.00 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 years 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 March 31, 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 U.S. 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 U.S. 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 U.S. 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 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.

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.

As a smaller reporting company (as defined in Rule 12b-2 of the Exchange Act), we are not required to provide the information called for by this Item 1A. Risk factors describing the major risks to our business can be found under Item 1A, “Risk Factors”, in our Annual Report on Form 10-K for the year ended December 31, 2021.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

All unregistered sales of our securities during the three months ended March 31, 2022, were previously disclosed in a Current Report on Form 8-K.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

None.
