Overview

We are a new type of pharmaceutical company committed to developing and expanding access to innovative medicines for some of the most prevalent disease areas, including cancer and immune-inflammatory conditions. Launched in January 2020, we are leveraging cutting-edge science, technology and strategic partnerships with stakeholders from across the healthcare system toward the goal of increasing access for patients around the world.

Today, we have more than 10 programs in our pipeline including clinical, preclinical and drug engineering targets for the treatment of oncology and immune-inflammatory conditions. We will continue to evaluate opportunities to add to our pipeline by in-licensing additional programs, leveraging our drug engineering collaborations and exploring combination partnerships. Select late-stage programs, each in-licensed in 2020, include: aumolertinib (EQ143), a third-generation epidermal growth factor receptor (EGFR) inhibitor; lerociclib (EQ132), a cyclin-dependent kinase (CDK) 4/6 inhibitor; and sugemalimab (EQ165, also known as CS1001), an anti-programmed death-ligand 1 (PD-L1) antibody.

We are in ongoing discussions with regulatory authorities in several geographies. Our marketing authorization applications for aumolertinib for the 1L treatment of adult patients with locally advanced or metastatic NSCLC with activating EGFR mutations and those with locally advanced or metastatic EGFR T790M mutation-positive NSCLC were accepted for review by the United Kingdom's Medicines and Healthcare products Regulatory Agency (MHRA) for a Great Britain license in June 2022 and by the European Medicines Agency (EMA) for a European Union-wide license in December 2022. Our marketing authorization applications for sugemalimab in combination with chemotherapy for the 1L treatment of adult patients with metastatic NSCLC were accepted for review by the MHRA for a Great Britain license in December 2022 and by the EMA for a European Union-

wide license in February 2023. Based on discussions with the FDA, in November 2022 and February 2023, we determined not to seek U.S. regulatory approval for sugemalimab in Stage IV NSCLC or in ENKTL, respectively.

On December 17, 2021 (the Closing Date), we consummated the merger transaction contemplated pursuant to a definitive merger agreement dated August 5, 2021 (the Merger Agreement), by and among Legacy EQRx, CMLS III and Clover III Merger Sub, Inc. (Merger Sub). As contemplated by the Merger Agreement, Merger Sub merged with and into Legacy EQRx, with Legacy EQRx surviving the merger as a wholly-owned subsidiary of CMLS III. As a result, CMLS III was renamed EQRx, Inc. and Legacy EQRx was renamed EQRx International, Inc. (such transactions, the Business Combination). The post combination company received net proceeds of approximately $1.3 billion upon the closing of the Business Combination, and the stockholders of Legacy EQRx are eligible to receive up to an additional 50,000,000 shares of CMLS III Class A common stock pursuant to the Merger Agreement. The newly combined business now operates under the Legacy EQRx management team.

Since inception, Legacy EQRx has, and following the Business Combination, we have focused primarily on organizing and staffing, business planning, raising capital, acquiring product candidates, conducting research and development activities for our programs, securing related intellectual property, and establishing strategic collaborations with payers and health systems. Since inception until the closing of the Business Combination, Legacy EQRx funded its operations through private equity financings. To date, it has raised an aggregate of approximately $2.2 billion of gross proceeds from the sale of convertible preferred shares, convertible preferred notes that were issued in 2019 and subsequently converted into shares of Series A convertible preferred stock (Series A), and the Business Combination and associated PIPE Financing (as defined below).

Since inception, we have incurred significant operating losses. Our operating losses were $355.9 million and $196.4 million for the years ended December 31, 2022 and 2021, respectively. We had an accumulated deficit of $527.6 million and $358.5 million as of December 31, 2022 and 2021, respectively. We expect to continue to incur significant expenses and operating losses for the foreseeable future, as we seek regulatory approvals for our pipeline candidates, manufacture drug product and drug supply, maintain and expand our intellectual property portfolio, as well as ensure we have adequate personnel, pay for accounting, audit, legal, regulatory and consulting services, and pay costs associated with maintaining compliance with Nasdaq listing rules and the requirements of the U.S. Securities and Exchange Commission (SEC), director and officer liability insurance, investor and public relations activities and other expenses associated with operating as a public company. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our preclinical studies, our clinical trials and our expenditures on other research and development activities and the status of our pipeline.

We do not currently have, and may never have, any product candidates approved for sale and have not generated any revenue to date. We will not generate revenue from product sales unless and until we complete clinical development for our product candidates and successfully obtain regulatory approval therefor. We may never generate revenues that are sufficient to achieve profitability. Additionally, our pipeline and areas of focus may change as we further the development of our current programs and identify new targets that meet the criteria for inclusion in our portfolio. For example, in November 2022 and in February 2023, we determined that we would no longer be pursuing regulatory approval in the United States for sugemalimab in Stage IV NSCLC or in ENKTL, respectively, because of additional regulatory requirements. Further, if we obtain regulatory approval for any of our product candidates, we expect to incur significant expenses related to developing our commercialization capabilities to support product sales, manufacturing and distribution activities. We will need substantial additional funding to pursue our longer-term business goals. Until we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of equity offerings and debt financings or other sources, such as potential collaboration agreements, strategic alliances and licensing arrangements. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on acceptable terms, or at all. Our failure to raise capital or enter into such agreements as, and when needed, could have a negative effect on our business, results of operations and financial condition.

Response to COVID-19

The full extent to which the ongoing COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including expenses, clinical trials and research and development costs, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19, ongoing emergence of additional COVID-19 variants and where outbreaks occur, and the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international markets. These situations, or others associated with COVID-19, could cause delays in our clinical trial plans, and our ability to obtain regulatory approvals, and could increase expected costs, all of which could have a material adverse effect on our business and financial condition. We implemented work-from-home and other policies, and are continuing to adapt to evolving federal, state and local health regulations. Because of the nature of our current operations, COVID-19 has not had a significant impact on our operations or financial results to date.

Business Combination Transaction

Pursuant to the terms of the Merger Agreement, on the Closing Date, each outstanding share of issued and outstanding common stock and preferred stock of Legacy EQRx was converted into the right to receive 0.627 shares (the Exchange Ratio) of the combined company's common stock, par value $0.0001 per share (Common Stock), resulting in the issuance of a total of 343,060,309 shares of Common Stock. Additionally, on the Closing Date, each option to purchase common stock of Legacy EQRx became an option to purchase shares of Common Stock of the combined company, subject to adjustment in accordance with the Exchange Ratio.

As of the Closing Date, each of the issued and outstanding shares of Class A common stock and Class B common stock of CMLS III was reclassified as Common Stock, and each of the issued and outstanding 8,693,333 private warrants and 11,039,957 public warrants became exercisable for shares of Common Stock.

In connection with the Business Combination, CMLS III entered into agreements with existing and new investors to subscribe for and purchase an aggregate of 120.0 million shares of Common Stock (the PIPE Financing) that resulted in gross proceeds of $1.2 billion upon the closing of the PIPE Financing. The closing of the Business Combination was a precondition to the PIPE Financing.

Following the Closing Date, former holders of Legacy EQRx common stock, preferred stock and options (collectively, the Earn-Out Service Providers) may receive a pro rata share of up to 35.0 million additional shares of Common Stock if at any time between the 12-month anniversary of the Closing Date and the 36-month anniversary of the Closing Date (the Earn-Out Period), the Common Stock price is greater than or equal to $12.50 for a period of at least 20 out of 30 consecutive trading days, and up to 15.0 million additional shares of common stock if at any time during the Earn-Out Period the Common Stock price is greater than or equal to $16.50 for a period of at least 20 out of 30 consecutive trading days (the Earn-Out Shares).

The Business Combination has been accounted for as a "reverse recapitalization" in accordance with U.S. generally accepted accounting principles (GAAP). Under the reverse recapitalization model, the Business Combination was treated as Legacy EQRx issuing equity for the net assets of CMLS III, with no goodwill or intangible assets recorded. Under this method of accounting, CMLS III was treated as the "acquired" company for financial reporting purposes. This determination was primarily based on the facts that subsequent to the merger, Legacy EQRx stockholders had a majority of the voting power of the combined company, Legacy EQRx operations comprised all of the ongoing operations of the combined company, Legacy EQRx governing body comprised a majority of the governing body of the combined company, and Legacy EQRx senior management comprised all of the senior management of the combined company.



Restructuring

                                      113

  Table of Contents

In February 2023, we announced a reduction in force to further increase operational efficiencies and streamline expenses. The actions under this plan are anticipated to result in cash expenditures of approximately $4.0 million and will be incurred in 2023. We expect this action, in addition to not filling positions following departures, will result in annualized cash savings of approximately $18.0 million.



Financial Overview

Revenue

To date, we have not recognized any revenue, including from product sales. If our development efforts for our product candidates are successful and result in regulatory approval, or we out-license (including sublicense) our products through agreements with third parties, we may generate revenue in the future. However, there can be no assurance as to when we will generate such revenue, if at all.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts and the development of our product candidates, salaries and benefits, and third-party license fees. We expense research and development costs as incurred, which include:

employee-related expenses, including salaries, bonuses, benefits, stock-based

? compensation, and other related costs for those employees involved in our

research and development efforts;

external research and development expenses incurred under agreements with CROs

? as well as consultants that conduct our preclinical studies and development

services;

? costs incurred under our collaboration agreements;

? costs related to manufacturing material for our preclinical and clinical

studies;

? costs related to compliance with regulatory requirements; and

? facilities, depreciation and other allocated expenses, which include direct and

allocated expenses for rent, utilities and insurance.

We track external research and development costs on a program-by-program basis once we have identified a product candidate. We do not allocate employee costs, facilities costs, including depreciation, or other indirect costs, to specific programs because these costs are, in many cases, deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to conduct our research activities as well as for managing our preclinical development, clinical development and manufacturing activities.

                       62,054     28,621
Total research and development expense              $ 228,495  $ 118,109

The successful development of our product candidates is highly uncertain. For example, we recently decided not to pursue U.S. market approval for sugemalimab in certain indications. We anticipate continuing to incur significant research and development expenses for the foreseeable future for indications in markets we continue to pursue, as we continue the development of such product candidates and manufacturing processes and conduct discovery and research activities for our preclinical programs. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future preclinical studies and clinical trials of our product candidates due to the inherently unpredictable nature of preclinical and clinical development. Clinical and preclinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the results of ongoing and future preclinical studies and clinical trials, regulatory developments and our ongoing assessments as to each product candidate's commercial potential. We expect that our expenses for indications in markets we continue to pursue will increase substantially, particularly due to the numerous risks and uncertainties associated with developing product candidates, including the uncertainty of:

the scope, rate of progress, and expenses of our ongoing research activities as

? well as any preclinical studies, clinical trials and other research and

development activities;

? establishing an appropriate safety profile with investigational new drug (IND)

enabling studies;

? successful enrollment in and completion of clinical trials;

? whether our product candidates show safety and efficacy in our clinical trials;

? receipt of marketing approvals from applicable regulatory authorities;

? the progress of our discovery collaborations with strategic partners;

? establishing commercial manufacturing capabilities or making arrangements with

third-party manufacturers;

? obtaining and maintaining patent and trade secret protection and regulatory

exclusivity for our product candidates;

? commercializing product candidates, if and when approved, whether alone or in

collaboration with others; and

? continued acceptable safety and efficacy profile of products following any


   regulatory approval.

  Table of Contents

Any changes in the outcome of any of these variables with respect to the development of our product candidates in preclinical and clinical development could mean a significant change in the costs and timing associated with the development of these product candidates. We may never succeed in achieving regulatory approval for any of our product candidates. We may obtain unexpected results from our clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on other product candidates. See Item 1A, "Risk Factors" for additional information on risk factors that could impact the discovery, development and regulatory approval of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of employee-related costs, including salaries, bonuses, benefits, stock-based compensation and other related costs for our executive and administrative functions. General and administrative expenses also include professional services, including legal, accounting and audit services and other consulting fees, costs associated with the partnership contracts we have in place with certain payers and health systems, as well as facility costs not otherwise included in research and development expenses, insurance and other general administrative expenses.

We expect that we will incur additional accounting, audit, legal, regulatory, compliance and director and officer insurance costs as well as investor and public relations expenses associated with operating as a public company. In addition, if and when we obtain regulatory approval for our product candidates, we expect to incur additional expenses related to the building of our team to support product sales and distribution activities.

Other Income (Expense)

Change in Fair Value of Contingent Earn-Out Liability

Change in fair value of contingent earn-out liability includes the changes in fair value of the Earn-Out Shares, which were classified as liabilities as part of the Business Combination consideration.

Change in Fair Value of Warrant Liabilities

Change in fair value of warrant liabilities includes the changes in fair value of the Private Warrants and the public warrants, which are classified as liabilities, and were assumed as part of the Business Combination.

Interest Income (Expense), Net

Interest income (expense), net primarily consists of income earned on our cash, cash equivalents and short-term investments.

Other Income (Expense), Net

Other income (expense) consists of miscellaneous income and expense unrelated to our core operations.

Research and Development Expenses

Research and development expense was $228.5 million for the year ended December 31, 2022, compared to $118.1 million for the year ended December 31, 2021. The increase of $110.4 million was primarily driven by a $51.3 million increase in discovery, preclinical and clinical development costs, a $33.4 million increase in employee related expenses driven by significant growth in our research and development headcount to support the development of our pipeline, a $14.2 million increase in consulting and professional fees, and a $11.1 million increase in information technology, facilities and other allocated expenses that support our overall research and development activities.

General and Administrative Expenses

General and administrative expense was $127.4 million for the year ended December 31, 2022, compared to $78.3 million for the year ended December 31, 2021. The increase of $49.1 million was primarily driven by a $34.5 million increase in employee related expenses driven by an increase in headcount to support the overall growth of the organization, a $14.9 million increase in consulting and professional fees, and a $4.3 million increase in information technology, facilities, overhead allocations and other expenses, partially offset by a decrease of $4.6 million in costs associated with the partnership contracts we have in place with certain payers and health systems.

Other Income, Net

Total other income, net was $186.8 million for the year ended December 31, 2022, compared to $96.4 million for the year ended December 31, 2021. The increase of $90.4 million was primarily due to an increase of $58.8 million and $6.9 million of non-cash income related to the remeasurement of the contingent earn-out liability and warrant liabilities, respectively, as of December 31, 2022, and a $24.7 million increase in interest income from our cash, cash equivalents and short-term investments, partially offset by a $0.1 million net change in other (expense) income.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have generated recurring net operating losses. We have not yet commercialized any products, and we do not expect to generate revenue from sales of any products until 2024 at the earliest, if at all. Since our inception, we have funded our operations primarily through proceeds from the issuance of preferred stock and common stock. To date, we have raised an aggregate of approximately $2.2 billion of gross proceeds from the sale of convertible preferred shares, convertible preferred notes that were issued in 2019 and subsequently converted into shares of Legacy EQRx Series A convertible preferred stock, the Business Combination and the concurrent PIPE Financing. As of December 31, 2022, we had cash, cash equivalents, short-term investments and restricted cash of $1.4 billion.

  Table of Contents

Funding Requirements

We believe that, prior to the consideration of revenue and associated costs from the potential future sales of any of our investigational products that may receive regulatory approval, our existing cash, cash equivalents and short-term investments of $1.4 billion on hand as of December 31, 2022 will enable us to fund our operating expenses and capital expenditure requirements into 2028, based on certain assumptions regarding our development programs and business development plans. We have based this estimate on assumptions that may prove to be wrong and may change, and we could expend our capital resources sooner than we expect or slow our spend such that it will last beyond 2028.

We expect to incur significant expenses and operating losses for the foreseeable future as we seek regulatory approvals, advance our product candidates, pursue commercialization of any approved product candidates and advance other candidates in our pipeline through preclinical and clinical development. In addition, we expect to incur additional costs associated with operating as a public company. Because of the numerous risks and uncertainties associated with research, development and commercialization of our product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future capital requirements will depend on many factors, including:

? the outcome, timing and costs of meeting regulatory requirements established by

the FDA, the EMA, the MHRA and other regulatory authorities;

? the progress of our efforts to acquire, in-license or sub-license rights to, or

otherwise discover (alone or in partnership) additional product candidates;

the timing and amount of milestone and royalty payments that we are required to

? make or eligible to receive under our current or future collaboration and

license agreements;

the costs and timing of future commercialization activities, including product

? manufacturing, marketing, sales and distribution, for any of our product

candidates for which we receive marketing approval;

? the costs and timing of completion of commercial-scale manufacturing

activities;

? efforts to develop and maintain our commercialization strategy by which payers

and health systems can access our future product candidates;

? the scope, progress, results and costs of our research programs and development

of any additional product candidates that we may pursue;

? our headcount growth and associated costs as we expand our research and

development and establish our commercial infrastructure;

the costs of expanding, maintaining and enforcing our intellectual property

? portfolio, including filing, prosecuting, defending and enforcing our patent

claims and other intellectual property rights;

the costs of defending potential intellectual property disputes, including

? patent infringement actions brought by third parties against us or any of our

product candidates;

? the effect of competing technological and market developments;

the revenue, if any, received from commercial sales of aumolertinib,

? sugemalimab and lerociclib (subject to receipt of marketing approvals therefor)

and any other product candidates for which we receive marketing approval; and




                                      118

  Table of Contents

? the costs of operating as a public company.

Until such time, if ever, as we generate substantial product revenues to support our cost structure, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations and other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our intellectual property, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us and/or may reduce the value of our Common Stock and other securities. Market volatility resulting from global economic and financial markets uncertainty, such as high inflation and the ongoing COVID-19 pandemic or other factors could also adversely impact our ability to access capital as and when needed. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant third parties rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.

Cash Flows

The following table sets forth the major sources and uses of cash for each of the periods (in thousands):



                                                               December 31,

Operating Activities

Cash flows from operating activities represent the cash receipts and disbursements related to all of our activities other than investing and financing activities. Operating cash flow is derived by adjusting our net loss for non-cash operating items such as depreciation, and stock-based compensation, as well as changes in operating assets and liabilities, which reflect timing differences between the receipt and payment of cash associated with transactions and when they are recognized in our results of operations.

Cash used in operating activities for the year ended December 31, 2022, was $287.3 million and consisted of net loss of $169.1 million plus non-cash adjustments of $129.1 million, partially offset by a net change in our operating assets and liabilities of $10.9 million. Non-cash items primarily included $161.7 million of gain from change in fair value of contingent earn-out and warrant liabilities, $9.2 million of net amortization of investment premiums and discounts, partially offset by $41.6 million of stock-based compensation expense. The net cash provided by changes in our operating assets and liabilities of $10.9 million was primarily due to a $1.9 million increase in accrued expenses, $12.0 million increase in accounts payable, partially offset by a $3.1 million increase in prepaid expense and other assets.

Cash used in operating activities for the year ended December 31, 2021, was $183.2 million and consisted of net loss of $100.0 million plus non-cash adjustments of $68.1 million and cash used by changes in our operating assets and liabilities of $15.1 million. Non-cash items primarily included $95.9 million of gain from change in fair value of contingent earn-out and warrant liabilities, partially offset by $26.2 million of stock-based compensation expense. The net cash used as a result of changes in our operating assets and liabilities of

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make judgments and estimates that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions. On an ongoing basis, we evaluate our judgments and estimates in light of changes in circumstances, facts, and experience. The effects of material revisions in estimates, if any, will be reflected in the consolidated financial statements prospectively from the date of change in estimates.

While our significant accounting policies are described in more detail in note 2 to our audited annual consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.

Contingent Earn-Out Shares

In connection with the Business Combination, the Earn-Out Service Providers are entitled to receive as additional merger consideration up to 50,000,000 additional shares of common stock if certain stock price triggers are achieved during the Earn-Out Period.

Earn-Out Shares allocated to Earn-Out Service Providers who held equity securities not subject to any vesting conditions or restrictions as of the Closing Date of the Business Combination are accounted for in accordance with Accounting Standards Codification (ASC) Topic 815, Derivatives and Hedging (ASC 815), as the Earn-Out



                                      120

  Table of Contents

Shares are not indexed to the Company's common stock. Pursuant to ASC 815, these Earn-Out Shares were accounted for as a liability at the Closing Date of the Business Combination and are subsequently remeasured at each reporting date with changes in fair value recorded as a component of other (expense) income, net in the consolidated statements of operations and comprehensive loss. The fair value of the Earn-Out Shares is determined using a Monte Carlo simulation valuation model that utilizes a distribution of potential outcomes on a monthly basis over the Earn-Out Period using the most reliable information available. The assumptions utilized in the calculation are based on the achievement of certain stock price milestones, including our common stock price, expected volatility, risk-free rate, expected term and expected dividend yield.

Earn-Out Shares allocated to Earn-Out Service Providers who held shares of common stock or options to purchase common stock that are subject to service-based vesting conditions or restrictions as of the Closing Date of the Business Combination are accounted for in accordance with ASC Topic 718, Share-Based Compensation (ASC 718), as the Earn-Out Shares are subject to forfeiture based on the satisfaction of certain service conditions. Pursuant to ASC 718, these Earn-Out Shares were measured at fair value at the grant date (the Closing Date) using a Monte Carlo simulation valuation model and will be recognized as expense over the time-based vesting period with a credit to additional paid-in-capital.

Warrant Liabilities

We do not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. We evaluate all of our financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

We have 11,039,957 public warrants and 8,693,333 private warrants that were issued by CMLS III. Each warrant entitles the holder to purchase one share of Common Stock, at an exercise price of $11.50 per share. The public warrants are publicly traded and are exercisable for cash unless certain conditions occur, such as the failure to have an effective registration statement related to the shares issuable upon exercise, or redemption by us under certain conditions, at which time the warrants may be eligible for a cashless exercise. The private warrants are redeemable for cash under certain conditions so long as they are held by the initial purchasers or their permitted transferees. If the private warrants are held by someone other than the initial purchasers or their permitted transferees, the private warrants are redeemable by us and exercisable by such holders on the same basis as the public warrants.

The warrants contain provisions that require them to be classified as derivative liabilities in accordance with ASC 815. Accordingly, at the end of each reporting period, changes in fair value during the period are recognized as a change in fair value of warrant liabilities within our consolidated statements of operations and comprehensive loss. We adjust the warrant liability for changes in the fair value until the earlier of (a) the exercise or expiration of the warrants and (b) the redemption of the warrants, at which time the warrants will be reclassified to additional paid-in capital.

The fair value of the public warrants is based on observable listed prices for such warrants at the end of each reporting period, and the fair value of the private warrants is equivalent to that of the public warrants as they have substantially the same terms; however, they are not actively traded.

Accrued and Prepaid Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development and manufacturing expenses. This process involves reviewing open contracts, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in arrears for services performed on a pre-determined schedule or when contractual milestones are met; however,



                                      121

  Table of Contents

some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. At each period end, we corroborate the accuracy of these estimates with the service providers and make adjustments, if necessary. Examples of estimated accrued research and development expenses include fees paid to:

? CROs in connection with performing research and development activities on our

behalf, including preclinical studies and clinical trials;

? Investigative sites or other service providers in connection with preclinical

or clinical trials;

? CMOs and other vendors related to product manufacturing and development and

distribution of preclinical and clinical supplies; and

Companies with whom we have a collaboration or in-licensing agreement, that

? perform research and development activities on our behalf, including

preclinical studies and clinical trials.

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts from CROs that conduct and manage studies on our behalf. The financial terms of these contracts are subject to negotiation and vary from contract to contract, which may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. In accruing fees, the Company estimates preclinical study and clinical trial expenses based on the services performed pursuant to contracts with research institutions, contract research organizations, and clinical manufacturing organizations, that conduct and manage preclinical studies and clinical trials on the Company's behalf based on actual time and expenses incurred by them. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid expense 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 may result in us reporting amounts that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development expenses.

Stock-Based Compensation

We measure stock-based awards granted to employees, non-employees and directors based on their fair value on the date of grant and recognize compensation expense over the requisite service period, which is generally the vesting period. We apply the straight-line method of expense recognition to all awards with only service-based vesting conditions. For awards with performance-based vesting conditions, we assess the probability that the performance conditions will be achieved at each reporting period. We use the accelerated attribution method to expense the awards over the requisite service period when the performance conditions are deemed probable of achievement.

We estimate the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model uses as inputs the fair value of our common stock and assumptions we make for the volatility of our common stock, the expected term of our common stock options, the risk-free interest rate for a period that approximates the expected term of our common stock options, and our expected dividend yield. We estimate the fair value of each restricted common stock granted based upon the difference between the fair value of our common stock on the grant date and the price per share paid by the purchasers.

As there was not a public market for our common stock prior to becoming publicly traded, the estimated fair value of our common stock was determined by the Board as of the date of grant of each option or restricted stock award, considering our most recently available third-party valuations of common stock and the Board's assessment of additional objective and subjective factors that it believed were relevant and which may have changed from the date of the most recent valuation through the date of the grant. These third-party valuations

were performed in accordance with the guidance outlined in the American Institute of Certified Public Accountants' Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. Our common stock valuations were prepared using either an option pricing method (OPM) or a hybrid method, both of which used market approaches to estimate our enterprise value. The OPM treats common stock and preferred stock as call options on the total equity value of a company, with exercise prices based on the value thresholds at which the allocation among the various holders of a company's securities changes. Under this method, the common stock has value only if the funds available for distribution to stockholders exceed the value of the preferred stock liquidation preferences at the time of the liquidity event, such as a strategic sale or a merger. The hybrid method is a probability-weighted expected return method (PWERM) where the equity value in one or more scenarios is calculated using an OPM. The PWERM is a scenario-based methodology that estimates the fair value of common stock based upon an analysis of future values for the company, assuming various outcomes. The common stock value is based on the probability-weighted present value of expected future investment returns considering each of the possible outcomes available as well as the rights of each class of stock. The future value of the common stock under each outcome is discounted back to the valuation date at an appropriate risk-adjusted discount rate and probability weighted to arrive at an indication of value for the common stock. A discount for lack of marketability of the common stock is then applied to arrive at an indication of value for the common stock.

In addition to the results of these third-party valuations, the Board also considered a number of objective and subjective factors to determine the fair value of our common stock on each grant date, including: (i) our stage of development and our business strategy; (ii) the progress of our research and development programs; (iii) the progress of our collaboration and licensing efforts; (iv) the illiquid nature of our common stock; (v) the prices at which we sold convertible preferred stock and the superior rights and preferences of the convertible preferred stock relative to our common stock at the time of each grant; (vi) external market conditions affecting the biotechnology industry, and trends within the biotechnology industry; (vii) our financial position, including cash on hand, and our historical and forecasted performance and operating results; and (viii) the likelihood of achieving a liquidity event.

Subsequent to the closing of the Business Combination, the Board determines the fair value of each share of common stock underlying stock-based awards based on the closing price of our common stock as reported by the Nasdaq on the date of grant.
