Overview


We are a preclinical stage biopharmaceutical company focused on advancing innovative precision therapeutics for debilitating and rare diseases.

From our inception, we have been focused on novel therapeutic approaches to improve the lives of patients diagnosed with Alzheimer's and other degenerative diseases. Our predecessor company, Cortexyme, Inc. ("Cortexyme") was initially founded on the seminal discovery of the presence of Porphyromonas gingivalis, or P. gingivalis, and its secreted toxic virulence factor proteases, called gingipains, in the relevant brain areas of both Alzheimer's and Parkinson's disease patients. The acquisition of Novosteo, Inc. in 2022, and the addition of new executive management has allowed us to strategically shift focus and prioritize the internal development of our innovative bone-targeting drug platform and lead compound NOV004 for development for rare skeletal diseases, bone fractures, and injury. At that time we changed our corporate name to Quince Therapeutics, Inc.

Business Acquisition

On May 19, 2022, we acquired all of the equity voting interests and completed the acquisition of Novosteo, Inc. ("Novosteo"), a Delaware corporation, pursuant to that certain Agreement and Plan of Merger and Reorganization dated as of May 9, 2022, by and among the Company, Quince Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of the Company, Quince Merger Sub II, LLC, a Delaware limited liability company and a wholly owned subsidiary of Company, Novosteo, and Fortis Advisors LLC, a Delaware limited liability company, solely in its capacity as the securityholders' representative. To effect this transaction a combination of transactions was executed with the intention of being treated as integrated steps in a single transaction resulting in Novosteo being a wholly owned subsidiary of the Company.

Pursuant to the terms of the Merger Agreement, at the closing of the Acquisition (the "Effective Time"), each share of capital stock of Novosteo that was issued and outstanding immediately prior to the Effective Time was automatically cancelled and converted into the right to receive 0.0911 shares of common stock, par value $0.001 per share. We issued 5,520,000 shares of common stock representing approximately 15.5% of outstanding stock on the completion of the Acquisition. We also assumed 507,108 options to purchase shares of our common stock upon conversion of the outstanding Novosteo options with awards retaining the same vesting and other terms and conditions as in effect immediately prior to consummation of the Acquisition.

In conjunction with the Acquisition, we appointed Novosteo executives Dirk Thye, M.D. as Chief Executive Officer, Dr. Karen Smith, M.D., Ph.D. as Chief Medical Officer and Brendan Hannah as Chief Business Officer. We also appointed Dr. Thye and Philip S. Low, Ph.D. to our Board of Directors as Class II and Class I directors, respectively.

Effective August 1, 2022, we changed our corporate name to Quince Therapeutics, Inc. and our ticker symbol to "QNCX".

Sale of legacy portfolio

On January 27, 2023, we sold our legacy small molecule protease inhibitor portfolio, including COR588, COR388, COR852, and COR803, pursuant to an asset purchase agreement with Lighthouse Pharmaceuticals, Inc., an entity co-founded by Casey Lynch, former chief executive officer of Quince's predecessor company Cortexyme, Inc. The Transaction was also consummated on January 27, 2023.

Upon the consummation of the Transaction, we received shares of common stock of Purchaser ("Common Stock") equal to seven and a half percent (7.5%) of the currently issued and outstanding Common Stock. The issuance is governed by a Stock Issuance Agreement entered into by us and Purchaser on January 27, 2023 (the "Stock Agreement"). The Stock Agreement contains certain anti-dilution rights and certain transfer restrictions on the Common Stock, including a right of first offer in favor of Purchaser and certain restrictions with respect to non-U.S. persons.



                                       58

--------------------------------------------------------------------------------

Pursuant to the terms of the Purchase Agreement, we are eligible to receive milestone payments up to $150 million on a product by product basis for the achievement of certain regulatory approvals and global net sales thresholds. Additionally, we are eligible to receive certain sales-based royalty payments on a product by product basis, ranging from high single-digit to mid-teens of annual net sales related to the two existing clinical stage programs, and low single-digit royalties for the preclinical programs, and certain sublicense income on a product by product basis, either in addition to milestone payments and royalties prior to Phase 2 initiation for COR588 or COR388, or in lieu of milestones payments and royalties after initiation of Phase 2 for COR588 or COR388 or for the preclinical programs.

We and the Purchaser have made certain covenants in the Purchase Agreement with respect to the transfer of the assets, including requisite filings to be made with regulatory authorities, and the milestone, royalty and sublicense payments and have agreed to indemnify each other for any breaches of such party's covenants, assumed liabilities (in the case of Purchaser) and retained liabilities, subject to certain customary survival periods and mitigation requirements. In addition, Purchaser granted to us an exclusive option until June 30, 2023 to obtain worldwide, royalty-free, fully-paid up, irrevocable and perpetual right and license under the transferred intellectual property related to COR388 to research, develop, manufacture, use, commercialize and otherwise exploit COR388 in any animal health indication.

We do not expect a material gain or loss on the sale of this portfolio after deal expenses to be recognized in the first quarter of 2023.

Out-licensing of NOV004

From our inception, we have been focused on novel therapeutic approaches to improve the lives of patients diagnosed with Alzheimer's and other degenerative diseases. Our predecessor company, Cortexyme, Inc. ("Cortexyme") was initially founded on the seminal discovery of the presence of Porphyromonas gingivalis, or P. gingivalis, and its secreted toxic virulence factor proteases, called gingipains, in the relevant brain areas of both Alzheimer's and Parkinson's disease patients. The acquisition of Novosteo, Inc. in 2022, and the addition of new executive management has allowed us to strategically shift focus and prioritize the internal development of our innovative bone-targeting drug platform and lead compound NOV004 for development for rare skeletal diseases, bone fractures, and injury. Following the Acquisition, we changed our corporate name to Quince Therapeutics, Inc.

On January 30, 2023, we provided an update on its development pipeline and business outlook for 2023. We intend to prioritize capital resources toward the expansion of our development pipeline through opportunistic in-licensing and acquisition of clinical-stage assets targeting debilitating and rare diseases. We plan to out-license our bone-targeting drug platform and precision bone growth molecule NOV004 designed for accelerated fracture repair in patients with bone fractures and osteogenesis imperfecta.

We discovered a broad bone-targeting drug platform designed to precisely deliver small molecules, peptides, or large molecules directly to the site of bone fracture and disease to promote more rapid healing with fewer off-target safety concerns compared to non-targeted therapeutics. Our discovery pipeline is positioned for rapid expansion across multiple skeletal therapeutic indications to address underserved therapeutic areas with major, unmet medical needs, including osteogenesis imperfecta, fractures, spinal fusion, and other severe bone diseases.

Corporate Restructuring

We approved the cost reduction program (the "Plan") to align operations with the changes in corporate strategy. Under the Plan, we are reducing headcount by approximately 47% through a reduction in its workforce. The reduction in force began in February 2023 and will be completed by April 2023. As a result, we expect to realize estimated annualized operating expense savings of approximately $10 million in the year ending December 31, 2023 (excluding share-based compensation and any one-time costs related to strategic actions).

In connection with the Plan, we estimate that we will incur expenses of approximately $0.6 million to $0.8 million, substantially all of which will be cash expenditures and other costs relating to the Plan through August 2023. We may incur other charges, including contract termination costs, retirement of fixed assets and facility-related costs and will record these expenses in the appropriate period as they are determined. These estimates are subject to a number of assumptions, and actual results may differ. we may also incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the Plan.

Financial Overview

Since commencing material operations in 2014, we have devoted substantially all of our efforts and financial resources to building our research and development capabilities, establishing our corporate infrastructure and most recently, executing our Phase



                                       59

--------------------------------------------------------------------------------

1a, Phase 1b and Phase 2/3 clinical trials of atuzaginstat (COR388), our Phase I SAD/MAD clinical trial of COR588 and to a lesser extent readying NOV004 for Phase 1 clinical trials.

To date, we have not generated any revenue and we have never been profitable. We have incurred net losses since the commencement of our operations. As of December 31, 2022, we had an accumulated deficit of $288.3 million. We incurred a net loss of $51.7 million in the year ended December 31, 2022. We do not expect to generate product revenue unless and until we obtain marketing approval for and commercialize a drug candidate, and we cannot assure you that we will ever generate significant revenue or profits.

To date, we have financed our operations primarily through the issuance and sale of convertible promissory notes and redeemable convertible preferred stock and common stock. From inception through December 31, 2022, we received net proceeds of approximately $303.7 million from the issuance of redeemable convertible preferred stock, convertible promissory notes and common stock.

On December 23, 2021, we entered into an Open Market Sales Agreement, with Jefferies, whereby we may sell up to $150.0 million in aggregate proceeds of common stock from time to time, through Jefferies as our sales agent. During the year ended December 31, 2022, we sold 51,769 shares of common stock, resulting in net proceeds of approximately $0.6 million, after commissions and other offering costs.

As of December 31, 2022 and 2021, we had cash, cash equivalents and short-term investments of $90.2 million and $106.8 million, respectively. The balances exclude long-term investments of $3.6 million and $19.9 million as of those same periods. Our cash equivalents, short-term and long-term investments are held in money market funds, certificate of deposits, repurchase agreements, investments in corporate debt securities, municipal debt obligations and government agency obligations.

Based on our current business plans including an analysis of our contractual obligations and commitments as of December 31, 2022 we believe that our existing cash, cash equivalents and investments will be sufficient to fund our planned operations through at least 2026, but does not include any costs or cash expenditures associated with in-licensing activities. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect.

In response to the reprioritization of our pipeline on January 30, 2023, the Board of Directors approved a cost reduction program to align operations with the change in corporate strategy to prioritize capital resources toward the expansion of its development pipeline through opportunistic in-licensing and acquisition of clinical-stage assets targeting debilitating and rare diseases. Under the Plan, we plan to reduce headcount by approximately 47% through a reduction in our workforce. The reduction in force began in February 2023 be completed by April 2023. In connection with the cost reduction program, we estimate that we will incur expenses of up to approximately $0.8 million, substantially all of which will be cash expenditures relating to severance through the second quarter of 2023. These estimates are subject to a number of assumptions, and actual results may differ.

We will need substantial additional funding to support our continuing operations and pursue our development strategy once we successfully in-license and acquire a clinical-stage asset targeting debilitating and rare diseases. We expect to finance our operations through the sale of equity, debt financings or other capital sources. Adequate funding may not be available to us on acceptable terms, or at all. If we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back or discontinue the development and commercialization of any drug candidates or delay our efforts to expand our product pipeline.

Critical Accounting Policies, Significant Judgments and Use of Estimates

For a description of our significant accounting policies, see Note 2 to our consolidated financial statements.

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions in certain circumstances that affect the amounts reported in the accompanying consolidated financial statements and related footnotes. Actual results may differ from these estimates. We base our judgments on our experience and on various assumptions that we believe to be reasonable under the circumstances.

Of our policies, the following are considered critical to an understanding of our consolidated financial statements as they require the application of subjective and complex judgment, involving critical accounting estimates and assumptions impacting our consolidated financial statements.

The critical accounting estimates relate to the following:

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses consist primarily of clinical trial and contract manufacturing expenses related to development of our drug candidates. Also included are personnel costs for our research and product development employees, non-personnel costs such as professional fees payable to third parties for preclinical studies and research services, laboratory supplies and equipment maintenance, product licenses, and other consulting costs.

We estimate preclinical and clinical study and research expenses based on the services performed, pursuant to arrangements with contract research organizations, or CROs that conduct and manage preclinical and clinical studies and research services on our behalf. Research and development contracts vary significantly in length, and may be for a fixed amount, based on milestones or deliverables, a variable amount based on actual costs incurred, capped at a certain limit, or for a combination of these elements. The financial terms of these agreements vary from contract to contract and may result in uneven expenses and payment flows. We estimate these expenses based on regular reviews with internal management personnel and external service providers as to the progress or stage of completion of services and the contracted fees to be paid for such services. Based upon the combined inputs of internal and external resources, if the actual timing of the performance of services or the level of effort varies from the original estimates, we will adjust the accrual accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting amounts that are too high or too low in any particular period. Our accrual is dependent, in part, upon the receipt of timely and accurate reporting from clinical research organizations and other third-party vendors. Payments associated with licensing agreements to acquire exclusive licenses to develop, use, manufacture and commercialize products that have not reached technological feasibility and do not have alternate commercial use are expensed as incurred. Payments made to third parties under these arrangements in advance of the performance of the related services by the third parties are recorded as prepaid expenses until the services are rendered.

To date, there have been no material differences from our accrued estimated expenses to the actual clinical trial expenses; and our methodology and assumptions used in developing these estimates have not changed materially during the periods presented. If we do not identify costs that we have begun to incur or if we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from our estimates, which could materially affect our results of operations. Adjustments to our accruals are recorded as changes in estimates become evident. Furthermore, based on amounts invoiced to us by our service providers, we may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as services are rendered. Due to the nature of estimates, we cannot assure you that we will not make changes to our estimates in the future as we become aware of additional information about the status or conduct of our research and development activities.

Stock-Based Compensation Expense

We measure and record compensation expense using the applicable accounting guidance for share-based payments related to stock options and performance-based awards granted to our directors and employees. The fair value of stock options is determined by using the Black-Scholes option-pricing model. The fair value of performance stock option awards is estimated at the date of grant, using the Monte Carlo Simulation model. The Black-Scholes and Monte Carlo Simulation valuation models incorporate assumptions as to stock price volatility, the expected life of options or awards, a risk-free interest rate and dividend yield. In valuing our stock options and market-based stock awards, significant judgment is required in determining the expected volatility of our common stock and the expected life that individuals will hold their stock options prior to exercising. Expected volatility for stock options is based on the historical volatility of our own stock and the stock of companies within our defined peer group. Further, our expected volatility may change in the future, which could substantially change the grant-date fair value of future awards and, ultimately, the expense we record.



                                       61

--------------------------------------------------------------------------------

We expense stock-based compensation for stock options and performance awards over the requisite service period. For awards with only a service condition, we expense stock-based compensation using the straight-line method over the requisite service period for the entire award. For awards with a market condition, we expense over the vesting period regardless of the value that the award recipients ultimately receive.

We estimate the fair value of stock-based compensation utilizing the Black-Scholes and Monte Carlo Simulation option-pricing models, which are impacted by the following variables:

Expected Term-We have opted to use the "simplified method" for estimating the expected term of options, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the option (generally 10 years).

Expected Volatility-Due to our limited operating history and a lack of company specific historical and implied volatility data, we have based our estimate of expected volatility on the historical volatility of our own stock and the stock of companies within our defined peer group. The historical volatility data was computed using the daily closing prices for the selected companies' shares during the equivalent period of the calculated expected term of the stock-based awards.

Risk-Free Interest Rate-The risk-free rate assumption is based on the U.S. Treasury instruments with maturities similar to the expected term of our stock options.

Expected Dividend-We have not issued any dividends in our history and do not expect to issue dividends over the life of the options and therefore have estimated the dividend yield to be zero.

Income Taxes

We prepare and file income tax returns based on our interpretation of each jurisdiction's tax laws and regulations. In preparing our consolidated financial statements, we estimate our income tax liability in each of the jurisdictions in which we operate by estimating our actual current tax expense together with assessing temporary differences resulting from differing treatment of items for tax and financial reporting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets.

Significant management judgment is required in assessing the realizability of our deferred tax assets. In performing this assessment, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In making this determination, under the applicable financial accounting standards, we are allowed to consider the scheduled reversal of deferred tax liabilities, projected future taxable income and the effects of tax planning strategies. In the event that actual results differ from our estimates, we adjust our estimates in future periods and we may need to increase or decrease our valuation allowance, when management determines it is more likely than not that some or all of the tax benefits will not be realized. This could materially impact our consolidated financial position and results of operations.

We account for uncertain tax positions using a "more likely than not" threshold for recognizing and resolving uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis and consider various factors including, but not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, information obtained during in process audit activities and changes in facts or circumstances related to a tax position. We adjust the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Our liabilities for uncertain tax positions can be relieved only if the contingency becomes legally extinguished, through either payment to the taxing authority or the expiration of the statute of limitations, the recognition of the benefits associated with the position meet the "more likely than not" threshold or the liability becomes effectively settled through the examination process. We consider matters to be effectively settled once the taxing authority has completed all of its required or expected examination procedures, including all appeals and administrative reviews, we have no plans to appeal or litigate any aspect of the tax position and we believe that it is highly unlikely that the taxing authority would examine or re-examine the related tax position. We also accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense. Judgments concerning the recognition and measurement of a tax benefit might change as new information becomes available.

Business Combination

We make certain judgments to determine whether transactions should be accounted for as acquisitions of assets or as business combinations. If it is determined that substantially all of the fair value of gross assets acquired in a transaction is concentrated in a single asset (or a group of similar assets), the transaction is treated as an acquisition of assets. We evaluate the inputs, processes, and outputs associated with the acquired set of activities. If the assets in a transaction include an input and a substantive process that



                                       62

--------------------------------------------------------------------------------

together significantly contribute to the ability to create outputs, the transaction is treated as an acquisition of a business. We account for business combinations using the acquisition method of accounting, which requires that assets acquired and liabilities assumed generally be recorded at their fair values as of the acquisition date.

The Company accounts for business combinations using the acquisition method pursuant to the Financial Accounting Standards Board (the "FASB") Accounting Standards Codification ("ASC") Topic 805. This method requires, among other things, that results of operations of acquired companies are included in the Company's financial results beginning on the respective acquisition dates, and that identifiable assets acquired and liabilities assumed are recognized at fair value as of the acquisition date. Intangible assets acquired in a business combination are recorded at fair value using a discounted cash flow model. The discounted cash flow model requires assumptions about the timing and amount of future net cash flows, the cost of capital and terminal values from the perspective of a market participant. Any excess of the fair value of consideration transferred (the "Purchase Price") over the fair values of the net assets acquired is recognized as goodwill. The fair value of identifiable assets acquired and liabilities assumed in certain cases may be subject to revision based on the final determination of fair value during a period of time not to exceed 12 months from the acquisition date. Legal costs, due diligence costs, business valuation costs and all other acquisition-related costs are expensed when incurred.

Goodwill

Goodwill represents the excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed. We test goodwill for impairment annually and when events or changes in circumstances indicate that the carrying value may not be recoverable. We have determined that we operate in a single segment and have a single reporting unit associated with the development and commercialization of pharmaceutical products. In performing the annual impairment test, the fair value of the reporting unit is compared to its corresponding carrying value, including goodwill. If the carrying value exceeds the fair value of the reporting unit an impairment loss will be recognized for the amount by which the reporting unit's carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. We performed our goodwill impairment test in October 2022 and concluded that goodwill was impaired as the carrying amount of the reporting unit exceeded its fair value, including goodwill. As a result, we recorded an impairment of $0.8 million in the quarter ended September 30, 2022.

Indentifiable Intangible Assets

We have acquired an intangible asset through our recent business combination with Novosteo, Inc. When significant identifiable intangible assets are acquired, we engage an independent third party valuation firm to assist in determining the fair values of these assets as of the acquisition date. Discounted cash flow models are typically used in these valuations, which require the use of significant estimates and assumptions, including but not limited to:

estimating the timing of and expected costs to complete the in-process projects;

projecting regulatory approvals;

estimating future cash flows including revenues and operating profits resulting from completed products and in-process projects; and

developing appropriate discount rates and probability rates by project.

We believe the fair value that we assign to the intangible asset acquired are based upon reasonable estimates and assumptions given available facts and circumstances as of the acquisition dates. No assurance can be given, however, that the underlying assumptions used to estimate expected cash flows will transpire as estimated. In addition, we are required to estimate the period of time over which to amortize the intangible assets, which requires significant judgment.

Impairment of Intangible Assets

Finite-lived intangible asset consist primarily of purchased developed technology and is amortized on a straight-line basis over their estimated useful lives. Indefinite lived intangible assets are not amortized, Intangible assets acquired in a business combination or an acquisition that are used in research and development activities (In-process research and development or IPR&D) shall be considered indefinite lived until the completion or abandonment of the associated research and development efforts. IPR&D is not amortized but is tested for impairment annually or when events or circumstances indicate that the fair value may be below the carrying value of the asset. If the carrying value of the assets is not expected to be recovered, the assets are written down to their estimated fair values. As of December 31, 2022, we had $5.9 million of IPR&D and we have recorded no asset impairment charge for the year ended December 31, 2022. Please refer to Note 15, Intangible Assets to the Notes to Consolidated Financial Statements of this Annual Report on Form 10­K, for further information about our intangible assets as of December 31, 2022. As of December 31, 2022, management performed a quantitative impairment evaluation of IPR&D intangible asset. The quantitative evaluation included a



                                       63

--------------------------------------------------------------------------------

discounted cash flow analysis to determine if the intangible asset had decreased in value. In order to determine the fair value of the intangible asset, the Company utilized an average of a discounted cash flow analysis and comparable public company analysis. The key assumptions associated with determining the estimated fair value include projected future revenue growth rates, projected cost of revenue, operating expenses, future income tax rates, and after tax free cash flow, and the discount rate. The assumptions used in the discount rate calculation were based on a peer company metrics to determine the weighted average cost of capital. This quantitative analysis resulted in the intangible asset fair value being above its carrying value, resulting in no impairment.

Components of Operating Results

Operating Expenses

Research and Development Expenses

Our research and development expenses consist of expenses incurred in connection with the research and development of our research programs. These expenses include payroll and personnel expenses, including stock-based compensation, for our research and product development employees, laboratory supplies, product licenses, consulting costs, contract research, regulatory, quality assurance, preclinical and clinical expenses, allocated rent, facilities costs and depreciation. We expense both internal and external research and development costs as they are incurred. Non-refundable advance payments and deposits for services that will be used or rendered for future research and development activities are recorded as prepaid expenses and recognized as an expense as the related services are performed.

To date, our research and development expenses have supported the advancement of atuzaginstat (COR388) and COR588 and to a lesser extent the clinical and regulatory development of NOV004. We expect our research and development expenses to decrease significantly from current levels until such time as we in-license a new product candidate. Predicting the timing or the costs to in-license a new drug candidate is difficult because of many factors.

In addition, the probability of success of any in-licensed product candidate will depend on numerous factors, including safety, efficacy, competition, manufacturing capability and commercial viability. We will need to determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of each product candidate, as well as an assessment of each product candidate's commercial potential.

Because our product candidates have not been in-licensed the outcome of these efforts is uncertain, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidate or whether, or when, we may achieve profitability.

General and Administrative Expenses

General and administrative expenses consist principally of personnel-related costs, including payroll and stock-based compensation, for personnel in executive, finance, human resources, business and corporate development, and other administrative functions, professional fees for legal, consulting, insurance and accounting services, allocated rent and other facilities costs, depreciation, and other general operating expenses not otherwise classified as research and development expenses.

We anticipate that our general and administrative expenses will remain consistent until we in-license a new drug candidate. We anticipate an increase of our general and administrative expense after the successful in-licensing of a drug candidate as the size of our business and research and development operations grows to support additional research and development activities.



                                       64

--------------------------------------------------------------------------------

Interest Income

Interest income consists primarily of interest earned on our short-term and long-term investments portfolio.

Other Expense, net

Other Expense, net consists primarily of the effects of foreign currency exchange rates.

Research and development expenses were $25.2 million for the year ended December 31, 2022, compared to $60.8 million for the year ended December 31, 2021, a decrease of $35.6 million. We anticipate our research and development expenses to decrease in the future until such time we acquire another clinical stage asset.

The costs for atuzaginstat (COR388) development, used in our GAIN Phase 2/3 clinical trial, decreased $24.2 million from the prior year due to the GAIN trial concluding in the fourth quarter of 2021. As a result, we experienced a decrease of $12.3 million in clinical trial costs, a $5.8 million decrease in drug manufacturing costs, a decrease in non-clinical studies and analysis related to the GAIN trial of $3.0 million, a $2.6 million decrease in consulting expenses related to atuzaginstat (COR388), a $0.3 million decrease in shipping expense related to shipments of COR388, and a decrease of $0.2 million related to the financing lease that was fully amortized in 2021.

Our Phase 1 SAD/MAD trial was completed in the second quarter of 2022 for our compound COR588 in healthy participants in Australia. As a result, the costs for COR588 increased by $0.5 million from the prior year. This increase was primarily



                                       65

--------------------------------------------------------------------------------

due to a $0.9 million increase for non-clinical studies and analysis to support COR588, offset by a decrease of $0.4 million in drug manufacturing costs and a decrease in consulting expenses of $0.1 million related to COR588.

As we sold our legacy protease inhibitor portfolio including COR388 and COR588 to Lighthouse Pharmaceuticals, Inc. in January 2023, we anticipate that any research and development expenses related to these assets to be minimal in the first quarter of 2023 and no additional expenses from the second quarter of 2023 onward.

For the year ended December 31, 2022, the costs for NOV004 increased by $1.8 million after the Novosteo, Inc. acquisition on May 19, 2022, primarily as a result of the increase in drug manufacturing costs as we prepared our compound for Phase 1 clinical trials. Due to the decision made on January 30, 2023 to align with our updated corporate strategy, our NOV004 costs will decrease significantly in 2023 from the current levels.

Additionally, other direct research costs decreased $2.0 million primarily due to the winddown of pipeline development of our two arginine gingipain inhibitors, COR788 and COR822, our 3CLpro inhibitor, COR803, COR852 and other preclinical research which were sold to Lighthouse Pharmaceutical in January 2023.

For the year ended December 31, 2022, we experienced a net decrease of $10.7 million in personnel related expenses due to a $8.7 million decrease in allocated stock-based compensation costs, a decrease of $4.4 million in wages and related personnel expenses as a result of our decreased headcount, offset by an increase in severance related expenses of $2.4 million as a result of our previously announced cost reduction program initiated in the first quarter of 2022.

Facilities and other research and development expenses decreased $1.0 million for the year ended December 31, 2022 primarily due to a $0.4 million decrease in the purchase of non-clinical supplies, a $0.3 million decrease in facilities and rent expense, a $0.2 million decrease in administration and depreciation expense, and a $0.1 million decrease in regulatory and quality assurance consulting costs.

General and Administrative Expenses

General and administrative expenses decreased by $3.5 million to $26.0 million for the year ended December 31, 2022 from $29.5 million for the year ended December 31, 2021. The decrease in general and administrative expenses was primarily due to an overall decrease in personnel expenses of $4.3 million, which is made up of a $4.6 million decrease in allocated stock-based compensation expense and $1.3 million decrease in personnel costs excluding stock based compensation related to our previously announced cost reduction program initiated in the first quarter of 2022, offset by increased severances expenses of $1.6 million. We also incurred a $2.1 million increase in legal, audit and other professional expenses related to the acquisition of Novosteo offset by a decrease of $0.6 million in marketing and investor relations expense and a $0.7 million decrease in consulting, corporate insurance expenses and other administrative expense due to our cost reductions efforts announced in the first quarter of 2022.

As a result of the previously mentioned cost reduction program, we anticipate our general and administrative expenses will decrease in 2023 compared to 2022 as we adjust our expenses to support our current in-licensing strategy.

Goodwill impairment charge

As of September 30, 2022, we conducted an impairment analysis of our goodwill that resulted from the purchase of Novosteo, Inc. in May 2022. That assessment included a qualitative assessment of deteriorating macro-economic conditions, including inflationary pressures, rising interest rates, and the continuing decline in our market capitalization from the date of acquisition. This qualitative assessment indicated that our goodwill was potentially impaired. To determine the extent, if any, by which our goodwill was impaired, we conducted additional quantitative analyses which resulted in our fair value being significantly below our current carrying value. As a result of the analyses, we recorded a non-cash goodwill impairment charge of $0.8 million for the year ended December 31, 2022.



Interest Income

                                       66

--------------------------------------------------------------------------------

For the year ended December 31, 2022, interest income increased $0.4 million or 72.3% due to increased yields on our investment portfolio which were partially offset by decreased average balances.

Other Expense

Other expense increased by $0.8 million for the year ended December 31, 2022, primarily due to unrealized losses resulting from changes in foreign exchange rates of $0.6 million, as well as a $0.2 million increase related to the San Diego lease impairment loss and loss on disposal of fixed assets.

Income tax

We recorded an $0.3 million income tax benefit for the year ended December 31, 2022 as a result of the acquisition of Novosteo, Inc. in May 2022.

Liquidity, Capital Resources and Plan of Operations

We have incurred cumulative net losses and negative cash flows from operations since our inception and anticipate we will continue to incur net losses for the foreseeable future. As of December 31, 2022, we had an accumulated deficit of $288.3 million. To date we have funded our operations primarily from the sales of our equity securities. As of December 31, 2022, we had cash, cash equivalents and investments of $93.8 million. Based on our current business plans, we believe that our existing capital resources will be sufficient to fund our projected operating requirements for at least the next twelve months. Our cash, cash equivalents, and marketable debt securities are held in a variety of deposit accounts, interest-bearing accounts, corporate bond securities, U.S government securities, debt securities in government-sponsored entities, and money market funds. Cash in excess of immediate requirements is invested with a view toward liquidity and capital preservation, and we seek to minimize the potential effects of concentration and credit risk.

On December 23, 2021, we entered into an Open Market Sales Agreement, with Jefferies, whereby we may sell up to $150.0 million in aggregate proceeds of common stock from time to time, through Jefferies as our sales agent. During the year ended December 31, 2022, we sold 51,769 shares of common stock, resulting in net proceeds of approximately $0.6 million, after commissions and other offering costs.

Capital Resources

Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures related to NOV004 and general and administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and accrued expenses.

In January 2023 we successfully out-licensed our legacy protease inhibitors to Lighthouse Pharmaceuticals, Inc. and announced our intention to out-license our current preclinical drug candidate NOV004. We also intend to concentrate our efforts on in-licensing clinical-stage assets targeting debilitating and rare diseases. Accordingly, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our future product candidates or whether, or when, we may achieve profitability.

In the near term, our primary uses of cash will be to fund our operations, including business development activities, and administrative personnel related expenses. Our uses of cash beyond the next 12 months will depend on many factors, including the general economic environment in which we operate and our ability to progress on our out-licensing and in-licensing timelines, which are uncertain.

We may continue to require additional capital to develop our drug candidates and fund operations for the foreseeable future. We may seek to raise capital through private or public equity or debt financings, collaborative or other arrangements with other companies, or through other sources of financing. Adequate additional funding may not be available to us on acceptable terms or at all. Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to pursue our business strategies. If we are able to in-license or acquire at least one clinical stage asset, we anticipate that we will need to raise substantial additional capital, the requirements of which will depend on many factors, including:

the progress, costs, trial design, results of and timing of any potential future trials;

the outcome, costs and timing of seeking and obtaining FDA and any other regulatory approvals;

the number and characteristics of drug candidates that we pursue;



                                       67

--------------------------------------------------------------------------------

our need to expand our research and development activities in connection with any assets that we may in-license;

the costs of acquiring, licensing or investing in businesses, drug candidates and technologies;

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 management and hire scientific and clinical personnel;

the effect of competing drugs and drug candidates and other market developments;

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

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

If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Any future debt financing into which we enter may impose upon us additional 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 other rights to our drug candidates in certain territories or indications that we would prefer to develop and commercialize ourselves.

Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide. However, based on our current business plans, we believe that our existing cash, cash equivalents and investments will be sufficient to fund our planned operations through at least 2026, but does not include any costs or cash expenditures associated with in-licensing activities.

Operating Activities

Net cash used in operating activities was $44.0 million for the year ended December 31, 2022. Cash used in operating activities in the year ended December 31, 2022 was primarily due to our net loss for the period of $51.7 million, which included non-cash expenses of $17.5 million, including $16.6 million in stock-based compensation, and a net decrease in accounts payable and accrued expenses and other current liabilities of $12.6 million and decreases in our current assets of $2.8 million.

Cash used in operating activities in the year ended December 31, 2021 was primarily due to our net loss for the period of $89.9 million, which included non-cash expenses of $31.3 million, including $29.9 million in stock-based compensation, and a net decrease in accounts payable and accrued expenses and other current liabilities of $3.3 million and increases in our current assets of $1.0 million.

Investing Activities



                                       68

--------------------------------------------------------------------------------

Cash provided in investing activities was $18.0 million in the year ended December 31, 2022, primarily related to the purchase of investments of $75.0 million, maturities of investments of $82.5 million, cash acquired from the Novosteo, Inc. acquisition of $10.6 million, and the purchase of equipment of $0.1 million.

Cash used in investing activities was $59.0 million in the year ended December 31, 2021, primarily related to the purchase of investments of $38.8 million, maturities of investments of $98.0 million and the purchase of equipment of $0.2 million.

Financing Activities

Cash provided by financing activities was $0.7 million in the year ended December 31, 2022, which consisted of proceeds from the issuance of common stock in connection with an open market sales agreement, net of issuance costs as well as proceeds from the exercise of options.

Cash provided by financing activities was $6.8 million in the year ended December 31, 2021, which consisted of net proceeds from the exercise of stock options during the period.

Contractual Obligations and Commitments

Material contractual obligations arising in the normal course of business primarily consist of operating and finance leases, drug manufacturing, preclinical and clinical contract obligations. See Note 6 to the Consolidated Financial Statements for amounts outstanding for operating and finance leases on December 31, 2022.

We enter into contracts in the normal course of business with third party contract organizations for clinical trials, non-clinical studies and testing, manufacturing, and other services and products for operating purposes. The amount and timing of the payments under these contracts varies based upon the timing of the services. We have recorded accrued expense of approximately $0.9 million in our consolidated balance sheet for expenditures incurred by these vendors as of December 31, 2022. We have approximately $5.5 million in cancellable future operating expense commitments based on existing contracts as of December 31, 2022. These obligations will be satisfied in the normal course of business, but generally no longer than 12 months. In connection with the cost reduction plan, we estimate that we will incur expenses of approximately $0.6 million to $0.8 million, substantially all of which will be cash expenditures and other costs relating to the Plan through August 2023. We currently do not have any long-term contractual commitments.

Indemnification

As permitted under Delaware law and in accordance with our bylaws, we indemnify our officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. We are also party to indemnification agreements with our officers and directors. We believe the fair value of the indemnification rights and agreements is minimal. Accordingly, we have not recorded any liabilities for these indemnification rights and agreements as of December 31, 2022 and December 31, 2021.
