Notes to the Condensed Consolidated Financial Statements

1. NATURE OF BUSINESS

EQRx, Inc. (the "Company"), formerly known as CM Life Sciences III Inc. ("CMLS III"), was incorporated in Delaware on January 25, 2021 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. On December 17, 2021 (the "Closing Date"), the Company consummated the merger transaction contemplated pursuant to a definitive merger agreement dated August 5, 2021 (the "Merger Agreement"), by and among EQRx, Inc. ("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 (such transactions, the "Business Combination"). As a result of the Business Combination, CMLS III was renamed EQRx, Inc., and Legacy EQRx was renamed EQRx International, Inc.

EQRx International, Inc. was formed on August 26, 2019 and launched in January 2020 as a new type of pharmaceutical company committed to developing and delivering innovative medicines to patients at radically lower prices.

The Company's mission is to improve health for all with great, innovative, affordable medicines so that people with life-changing or chronic conditions can gain access to the medicines they need, physicians can treat patients without barriers to prescribing, and health systems can afford to make those medicines available, without restrictions, to the populations they serve in a financially sustainable manner. This approach starts with assembling a catalog of medicines at significant scale, targeting some of the most innovative clinical opportunities and highest drug cost categories of today and tomorrow, with an initial focus on oncology and immune-inflammatory diseases.

Assuming it is successful in obtaining regulatory approval, the Company plans to offer its catalog of innovative medicines to payers and health systems at radically lower prices, through a simple and transparent pricing model without surprise price increases. The Company is also assembling a Global Buyers Club by entering into long-term, trusted strategic partnerships with private and public payers, providers and health systems so they and the patients they serve can gain access to its future medicines, if approved, at radically lower prices. The Company will offer simple and transparent pricing models to provide an opportunity for dramatic savings in these high-cost drug areas. The Company's current pipeline of product candidates includes two late-stage programs each in-licensed in 2020: aumolertinib (EQ143), a third-generation epidermal growth factor receptor (EGFR) inhibitor, and sugemalimab (EQ165, also known as CS1001), an anti-programmed death-ligand 1 (PD-L1) antibody.

The Business Combination was accounted for as a reverse recapitalization with Legacy EQRx being the accounting acquirer and CMLS III as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the condensed consolidated financial statements and accompanying notes represents the accounts of Legacy EQRx and its wholly-owned subsidiaries. The shares and net loss per common share prior to the Business Combination have been retroactively restated as shares reflecting the exchange ratio established in the Merger Agreement. For additional information on the Business Combination, refer to note 4 to these condensed consolidated financial statements.

Risks and Uncertainties

The Company is subject to risks and uncertainties common to companies in the biotechnology industry, including, but not limited to, identification of product candidates, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, establishment of relationships with strategic partners, and the ability to secure additional capital to fund operations. Product candidates in-licensed and to be in-licensed, discovered alone or

5

Table of Contents

in partnership, acquired or developed will require significant research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure, and extensive compliance and reporting capabilities.

There can be no assurance that the Company's ability to identify product candidates and subsequently research and develop those product candidates will be successfully completed, that adequate protection for the Company's intellectual property will be obtained both inside and outside the U.S., that any products developed will obtain necessary government regulatory approval, or that any approved products will be commercially viable. Even if the Company's product identification and development efforts are successful, it is uncertain when, if ever, the Company will generate significant revenue from product sales, and the Company may be subject to significant competitive or litigation risks.

In March 2020, the World Health Organization characterized the novel COVID-19 virus as a global pandemic. The full extent to which the ongoing COVID-19 pandemic will directly or indirectly impact the Company's 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 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 the Company's clinical trial plans and could increase expected costs, all of which could have a material adverse effect on the Company's business and its financial condition. COVID-19 has not had a significant impact on the operations or financial results of the Company to date.

Liquidity

The Company has limited operating history and anticipates that it will incur losses for the foreseeable future as it builds its internal infrastructure, identifies and acquires product candidates, conducts the research and development of its product candidates, and seeks marketing approval for its late-stage programs. The Company had net income of $20.7 million for the three months ended March 31, 2022, primarily due to non-cash income of $105.7 million resulting from the recognition of the contingent earn-out liability and warrant liabilities at fair value at March 31, 2022, as compared to a net loss of $26.8 million for the three months ended March 31, 2021. Prior to the Business Combination, the Company funded its operations with its initial public offering, and its subsidiary, EQRx International, Inc., funded its operations with borrowings under the convertible promissory notes it issued in October 2019 and from the sale of convertible preferred stock.

As of March 31, 2022, the Company had cash, cash equivalents and restricted cash of $1.6 billion and an accumulated deficit of $337.8 million. The Company expects that its cash, cash equivalents and restricted cash outstanding as of March 31, 2022 will be sufficient to fund its obligations for at least twelve months from the date of issuance of these condensed consolidated financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying condensed consolidated interim financial statements and accompanying notes include the accounts of the Company and its wholly-owned subsidiaries EQRx, International, Inc., EQRx Securities Holding Corporation and an immaterial wholly-owned foreign subsidiary. All intercompany transactions and balances have been eliminated in consolidation. The accompanying condensed consolidated interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information.

Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated interim

6

Table of Contents

financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2021 and the related notes, which provide a more complete discussion of the Company's accounting policies and certain other information. The December 31, 2021 condensed consolidated balance sheet was derived from the Company's audited financial statements. These unaudited condensed consolidated interim financial statements have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company's condensed consolidated financial position as of March 31, 2022 and its results of operations and cash flows for the three months ended March 31, 2022 and 2021. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022, or for any other future annual or interim period.

​

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions, based on judgments considered reasonable, which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. The Company bases its estimates and assumptions on historical experience, known trends and events and various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the valuation of the Company's convertible promissory notes and common stock, the accrual of research and development and manufacturing expenses, stock-based compensation expense, the valuation of the contingent earn-out liability, and the fair value of warrants. Changes in estimates are recorded in the period in which they become known. Due to the risks and uncertainties involved in the Company's business and evolving market conditions and, given the subjective element of the estimates and assumptions made, actual results may differ from estimated results.

​

3. CASH, CASH EQUIVALENTS AND RESTRICTED CASH

The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash equivalents as of March 31, 2022 and December 31, 2021 consist of U.S. government money market funds, commercial paper, and U.S. treasury bills (see note 5).

Amounts included in restricted cash consists of cash held to collateralize a letter of credit issued as a security deposit in connection with the Company's lease of its corporate facility located in Cambridge, MA.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the applicable condensed consolidated balance sheet that sums to the total of the same such amounts shown in the condensed consolidated statement of cash flows (in thousands):

4. BUSINESS COMBINATION

Summary of Business Combination

On December 17, 2021, Merger Sub, a wholly-owned subsidiary of CMLS III, merged with Legacy EQRx, with Legacy EQRx surviving as a wholly-owned subsidiary of CMLS III, a related party. 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 entity'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.

The Company assumed 11,039,957 publicly-traded warrants ("Public Warrants") and 8,693,333 private placement warrants issued in connection with CMLS III's initial public offering ("Private Warrants" and, together with the Public Warrants, the "Warrants"). Each Warrant entitles the holder to purchase one share of the Company's common stock, par value $0.0001, at an exercise price of $11.50 per share.

As of the Closing Date, each of the issued and outstanding shares of Class A common stock and Class B common stock ("Founders Stock") of CMLS III automatically converted, on a one-for-one basis, into shares of Common Stock, and each of the issued and outstanding Private Warrants and Public Warrants automatically converted into warrants to acquire 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.

The number of shares of Common Stock outstanding immediately following the consummation of the Business Combination was as follows:

​

The Business Combination has been accounted for as a "reverse recapitalization" in accordance with 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 fact that subsequent to the merger, Legacy EQRx stockholders held a majority of the voting power of the combined company, Legacy EQRx comprised all of the ongoing operations of the combined entity, Legacy EQRx 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.

Net Proceeds

In connection with the Business Combination, the Company received net proceeds of $1.3 billion from the merger and related PIPE Financing. The following table summarizes the elements of the net proceeds from the Business Combination and PIPE Financing transactions (in thousands):

​

Earn-Out Shares

Following the Closing Date, holders of Legacy EQRx securities and options ("Earn-Out Service Providers") are entitled to receive as additional merger consideration of up to 50,000,000 shares of Common Stock (the "Earn-out Shares"), comprised of two separate tranches, for no consideration upon the occurrence of certain triggering events. Earn-Out Service Providers may receive a pro rata share of up to 35,000,000 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 ("Tranche 1"), and up to 15,000,000 additional share 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 ("Tranche 2").

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 ASC Topic 815, Derivatives and Hedging ("ASC 815"), as the Earn-Out Shares are not indexed to the 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 subsequently remeasured at each reporting date with changes in fair value recorded as a component of other income (expense), net in the consolidated statements of operations and comprehensive income (loss). The fair value of the Earn-Out Shares accounted for under ASC 815 was $240.1 million at the Closing Date and was recognized as a liability in the consolidated balance sheet.

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 time-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) and will be recognized as expense over the time-based vesting period with a credit to additional paid-in-capital. The fair value of the Earn-Out Shares accounted for under ASC 718 was $43.4 million at the Closing Date.

Items Measured at Fair Value on a Recurring Basis

The following tables present information about the Company's assets and liabilities that are measured at fair value on a recurring basis (in thousands):

​

​

In determining the fair value of its cash equivalents at each date presented above, the Company relied on quoted prices for similar securities in active markets or using other inputs that are observable or can be corroborated by observable market data.

The fair value of the Public Warrants was based on observable listed prices for such warrants. 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. The change in the fair value of the Warrants during the three months ended March 31, 2022 was as follows (in thousands):

10

Table of Contents

The carrying amounts of the Company's prepaid and other current assets, accounts payable and accrued liabilities, approximate fair value due to their short maturities.

Level 3 Financial Instruments

The Earn-Out Shares accounted for under ASC 815 are categorized as Level 3 fair value measurements within the fair value hierarchy because the Company estimates projections over a ten-year period utilizing unobservable inputs. Contingent earnout payments involve certain assumptions requiring significant judgment and actual results can differ from assumed and estimated amounts.

In determining the fair value of the contingent earn-out liabilities, the Company uses a Monte Carlo simulation model using a distribution of potential outcomes on a monthly basis prioritizing the more reliable information available. The assumptions utilized in the calculation are based on the achievement of certain stock price milestones, including the Company's stock price at each reporting period, expected volatility, risk-free rate, expected term and expected dividend yield.

The Earn-Out Shares subject to liability accounting were valued using the following assumptions under the Monte Carlo simulation valuation model:

8. CONVERTIBLE PREFERRED STOCK

Series A Convertible Preferred Stock

On January 10, 2020, the Company entered into a Series A Preferred Stock Purchase Agreement ("Series A Purchase Agreement"), pursuant to which it could raise up to approximately $218.0 million through the issuance of up to 234,257,469 Series A shares, excluding the issuance of shares of Series A upon conversion of the October 2019 Notes, par value $0.0001 per share, for $0.9306 per share ("Series A Original Issue Price").

During 2020, the Company sold a total of 234,257,469 shares of its Series A for gross proceeds of $218.0 million, excluding the shares of Series A issued upon conversion of the October 2019 Notes.

Series B Convertible Preferred Stock

On November 2, 2020 (the "Series B Original Issue Date"), the Company entered into a Preferred Stock Purchase Agreement, as amended on November 18, 2020 ("Series B Purchase Agreement"), pursuant to which it immediately issued 98,654,203 shares of Series B convertible preferred stock ("Series B") (the "Series B Initial Closing") at a purchase price of $2.7419 per share (the "Series B Original Issue Price").

Based upon the terms of the Series B Purchase Agreement, after the Series B Initial Closing, the Company could sell, in one or more additional closings, 191,473,066 additional shares of Series B to one or more purchasers who are existing stockholders of the Company or are mutually acceptable to the Company and its board of directors, provided that (a) such subsequent closings were consummated prior to March 31, 2021, (b) each such additional purchaser became a party to the Series B transaction agreements, and (c) the Company could not sell and issue more than 191,473,066 shares in aggregate in all closings under the Series B Purchase Agreement ("Series B Additional Closings"). During the year ended December 31, 2020, the Company issued a total of 181,261,150 shares of Series B for aggregate proceeds of $497.0 million in the Series B Initial Closing and through Series B Additional Closings.

On January 28, 2021, the Company further amended the Series B Purchase Agreement to increase the number of shares of Series B that could be issued under the agreement from 191,473,066 to 207,885,043. In January and February 2021, the Company issued an additional 26,133,332 additional shares of Series B at the Series B Original Issued Price for aggregate proceeds of $71.7 million.

Conversion of Convertible Preferred Stock

Pursuant to the terms of the Merger Agreement, upon the Closing Date, each share of Legacy EQRx convertible preferred stock issued and outstanding immediately prior to the Closing Date was converted into shares of the

12

Table of Contents

combined company's common stock using an exchange ratio of 0.627. A retroactive adjustment has been applied to all periods presented to reflect the Business Combination and reverse recapitalization as discussed further in note 4 and note 10.

​

9. WARRANTS

CMLS issued the Public Warrants and Private Warrants, which have an exercise price of $11.50 and were deemed assumed by the Company in connection with the Business Combination. In accordance with the warrant agreements, the Warrants became exercisable on January 16, 2022. The Warrants will expire five years after the completion of the Business Combination, or earlier upon redemption or liquidation.

Subsequent to the Business Combination, the Public Warrants and Private Warrants meet liability classification requirements because the Warrants contain provisions whereby adjustments to the settlement amount of the warrants are based on a variable that is not an input to the fair value of a "fix-for-fixed" option and the existence of the potential for net cash settlement for the warrant holders in the event of a tender offer. In addition, the Private Warrants are potentially subject to a different settlement amount depending upon the holder of the Private Warrants, which precludes them from being considered indexed to the entity's own stock. Therefore, the Warrants are classified as liabilities on the condensed consolidated balance sheets at March 31, 2022 and December 31, 2021. As of March 31, 2022, no Warrants have been exercised or redeemed.

As of March 31, 2022, the following Warrants were outstanding:

​

Public Warrants

The Public Warrants became exercisable for shares of Common Stock commencing on January 16, 2022. The Public Warrants will expire five years after the completion of the Business Combination, or earlier upon redemption or liquidation.

Redemption of Warrants When the Price per Share of Common Stock Equals or Exceeds $18.00

The Company may redeem the outstanding Warrants:

Redemption of Warrants When the Price per Share of Common Stock Equals or Exceeds $10.00

The Company may redeem the outstanding warrants:

13

Table of Contents

The "fair market value" of the Common Stock shall mean the volume weighted average price of the Common Stock during the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of Warrants. The Company will provide its Warrant holders with the final fair market value no later than one business day after the 10-trading day period described above ends. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 shares of common stock per warrant (subject to adjustment).

No fractional shares will be issued upon exercise of the Warrants.

Private Warrants

The Private Warrants are identical to the Public Warrants, except that the Private Warrants and the Common Stock issuable upon the exercise of the Private Warrants were not transferable, assignable or saleable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, except as described above in the discussion of the redemption of warrants when the price per share of Common Stock equals or exceeds $10.00, the Private Warrants will be exercisable on a cashless basis and be non-redeemable 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 will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

The Private Warrants and the Public 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 the consolidated statements of operations and comprehensive income (loss). The Company adjusts the warrant liability for changes in the fair value until the earlier of (a) the exercise or expiration of the Warrants or (b) the redemption of the Warrants, at which time the Warrants will be reclassified to additional paid-in capital.

Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

The Warrants were valued on March 31, 2022 and December 31, 2021 using the listed trading price of $0.87 and $1.07, respectively.

10. STOCKHOLDERS' EQUITY

The consolidated statement of stockholders' equity for the three months ended March 31, 2021 has been retroactively adjusted to reflect the Business Combination and reverse recapitalization (see note 4).

Preferred Stock

Upon closing of the Business Combination, pursuant to the terms of its Amended and Restated Certificate of Incorporation, the Company became authorized to issue 2,000,000 shares of preferred stock with a par value $0.0001 per share. The Company's board of directors has the authority, without further action by the stockholders to issue such shares of preferred stock in one or more series, to establish from time to time the

number of shares to be included in each such series, and to fix the dividend, voting, and other rights, preferences and privileges of the shares. There were no issued and outstanding shares of preferred stock as of March 31, 2022.

Upon the closing of the Business Combination, pursuant to the terms of the Company's Amended and Restated Certificate of Incorporation, the Company became authorized to issue 1,250,000,000 shares of Common Stock with a par value of $0.0001 per share.

Each share of Common Stock entitles the holder to one vote on all matters submitted to a vote of the Company's stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors, if any, subject to the preferential dividend rights of the Company's preferred stock.

As of March 31, 2022, 537,650,901 shares of Common Stock were issued including 40,674,552 shares sold to the Company's founders, employees and advisors under restricted stock agreements (see note 11), and 50,000,000 Earn-Out Shares.

​

11. STOCK-BASED COMPENSATION

In January 2020, the Company's board of directors and stockholders adopted the 2019 Stock Option and Grant Plan (the "2019 Plan"). On December 16, 2021, the Company's board of directors and the stockholders adopted the 2021 Option Grant and Incentive Plan (the "2021 Plan"), which became effective upon the closing of the Business Combination. The 2021 Plan provides for the issuance of incentive stock options or non-qualified stock options, restricted stock awards, unrestricted stock awards, restricted stock units, or any combination of the foregoing to employees, board members, consultants and advisors.

Upon completion of the Business Combination, the Company ceased issuing awards under the 2019 Plan. The total number of shares of Common Stock that may be issued under the 2021 Plan was 59,353,357 at plan adoption ("Share Reserve"). The 2021 Plan provides that the Share Reserve will automatically increase on January 1, 2022 and each January 1 thereafter, by 5% of the outstanding number of shares of Common Stock on the immediately preceding December 31 or such lesser number of shares as determined by the Compensation and Talent Development Committee (the "Annual Increase"). Share limits under the 2021 Plan are subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization. The shares of Common Stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of stock, expire or are otherwise terminated (other than by exercise) under each of the 2021 Plan and the 2019 Plan will be added back to the Share Reserve. As of March 31, 2022, 67,467,246 shares remain available for future grant under the 2021 Plan.

Stock-based compensation expense included in the Company's condensed consolidated statements of operations and comprehensive income (loss) was as follows (in thousands):

Stock Options

A summary of stock option activity for employee and nonemployee awards during the three months ended March 31, 2022 is presented below:

​

The fair value of each stock option was estimated using a Black-Scholes option-pricing model with the following weighted-average assumptions:

​

The weighted average grant-date fair value of stock options granted during the three months ended March 31, 2022 and 2021 was $1.72 and $1.60 per share, respectively. The fair value of options that vested during the three months ended March 31, 2022 and 2021 was $3.5 million and $0.3 million, respectively. The aggregate intrinsic value of options exercised (i.e., the difference between the market price at exercise and the price paid by employees to exercise the option) during the three months ended March 31, 2022 was $35.1 thousand. There were no options exercised during the three months ended March 31, 2021.

As of March 31, 2022, there was $64.1 million of total unrecognized compensation expense related to unvested stock options that the Company expects to recognize over a remaining weighted-average period of 3.3 years.

Restricted Common Stock

As of March 31, 2022, the Company had issued a total of: (i) 5,603,522 shares of restricted Common Stock to employees and advisors of the Company under the 2019 Plan; (ii) 627,000 shares of restricted Common Stock to a strategic partner outside of the 2019 Plan as partial compensation for future services; and (iii) 34,865,902 shares of restricted Common Stock to its founders, employees and advisors outside of the 2019 Plan.

All shares of restricted Common Stock were issued subject to restricted stock purchase agreements between the Company and each purchaser. Pursuant to the restricted stock purchase agreements, the Company, at its discretion, has the right to repurchase unvested shares if the holder's relationship with the Company is terminated at the lesser of the original purchase price of the shares, or the fair value of the shares at the time of repurchase. The restricted shares are not deemed to be issued for accounting purposes until they vest and are therefore excluded from shares outstanding until the repurchase right lapses and the shares are no longer subject to the repurchase feature.

A summary of the Company's restricted Common Stock activity and related information during the three months ended March 31, 2022 is as follows:

​

As of March 31, 2022, there was $2.1 million of total unrecognized compensation expense related to unvested restricted Common Stock that the Company expects to recognize over a remaining weighted-average period of 2.9 years.

​

Earn-Out Shares

​

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 time-based vesting conditions or restrictions as of the Closing Date of the Business Combination are accounted for in accordance with ASC 718. Pursuant to ASC 718, these Earn-Out Shares were measured at fair value at the grant date (the Closing Date) and will be recognized as expense over the time-based vesting period using the accelerated attribution method with a credit to additional paid-in-capital. The fair value of the Earn-Out Shares accounted for under ASC 718 was $43.4 million at the Closing Date.

The following table summarizes the activity associated with Earn-Out Shares accounted for pursuant to ASC 718 during the three months ended March 31, 2022:

​

During the three months ended March 31, 2022, the Company recognized $8.1 million of stock-based compensation expenses associated with the Earn-Out Shares. As of March 31, 2022, unrecognized compensation costs related to the Earn-Out Shares was $18.4 million and is expected to be recognized over a weighted-average period of 1.4 years.

12. LICENSE AGREEMENTS AND DISCOVERY COLLABORATIONS

License Agreements

Aumolertinib - Hansoh

On July 22, 2020, the Company entered into a collaboration and license agreement with Hansoh (Shanghai) Healthtech Co., LTD and Jiangsu Hansoh Pharmaceutical Group Company LTD, (collectively "Hansoh") under which it acquired an exclusive license for the research, development, and commercialization of aumolertinib, a third generation EGFR inhibitor, worldwide, with the exception of the People's Republic of China, and its

17

Table of Contents

territories and possessions, including Hong Kong, Macau and Taiwan (the "Hansoh Territory"). The license agreement also provides the Company with a non-exclusive license in the Hansoh Territory to research, develop and export aumolertinib for purposes of obtaining regulatory approval for, and commercialization of aumolertinib for use outside of the Hansoh Territory.

Under the terms of the license agreement, the Company received an exclusive license to develop aumolertinib for any and all uses for the treatment of cancer, cancer-related and immune-inflammatory diseases in humans at its own cost and expense in the Company's territory. The Company was obligated to make an upfront non-refundable, non-creditable payment of $25.0 million. If the Company succeeds in developing and commercializing aumolertinib, Hansoh will be eligible to receive (i) up to $90.0 million in development and regulatory milestone payments, and (ii) up to $420.0 million in sales milestone payments. In the event that Hansoh elects to opt out of sharing certain global development costs in accordance with the terms of the license agreement, the total potential development and regulatory payments Hansoh is eligible to receive will be reduced to $55.0 million, and the total potential sales milestone payments will be reduced to $350.0 million.

Hansoh is also eligible to receive royalties on worldwide (except the Hansoh Territory) net sales of any products containing aumolertinib which range from mid-single digits to low teens, subject to potential reduction following the launch of certain generic products. The royalties for aumolertinib will expire on a product-by-product and country-by-country basis upon the later to occur of (i) the expiration of all valid patent claims covering the compounds in a country, (ii) the expiration of all regulatory exclusivities for aumolertinib in a country, or (iii) 11 years following the first commercial sale of aumolertinib in a country.

The Company has the right to terminate the license agreement with Hansoh for any or no reason upon at least 180 days prior written notice to Hansoh. Either party may terminate the license agreement in its entirety for the other party's material breach if such party fails to cure the breach. Either party may also terminate the agreement in its entirety upon certain insolvency events involving the other party.

The Company evaluated the license agreement with Hansoh under ASC 805 and concluded that because the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar assets, the transaction did not meet the requirements to be accounted for as a business combination and therefore was accounted for as an asset acquisition

Sugemalimab/Nofazinlimab - CStone

On October 26, 2020, the Company entered into a license agreement with CStone Pharmaceuticals ("CStone") under which it acquired an exclusive license for the research, development, and commercialization of CStone's sugemalimab, an anti-PD-L1 monoclonal antibody, and nofazinlimab, an anti-PD-1 monoclonal antibody, worldwide, with the exception of Mainland China, Taiwan, Hong Kong and Macau (the "CStone Territory").

Under the terms of the license agreement, the Company received an exclusive license to develop sugemalimab and nofazinlimab for any and all uses at its own cost and expense in the Company's territory. The Company was obligated to make an upfront non-refundable, non-creditable payment of $150.0 million, including $10.0 million as CStone received notification that the U.S. Food and Drug Administration designated sugemalimab as a breakthrough therapy. If the Company succeeds in developing and commercializing sugemalimab, CStone will be eligible to receive (i) up to $107.5 million in development and regulatory milestone payments, and (ii) up to $565.0 million in sales milestone payments. If the Company succeeds in developing and commercializing nofazinlimab, CStone will be eligible to receive (i) up to $75.0 million in development and regulatory milestone payments, and (ii) up to $405.0 million in sales milestone payments.

CStone is also eligible to receive royalties on worldwide (excluding the CStone Territory) net sales of any products containing sugemalimab and nofazinlimab ranging from the low teens to the high teens for sugemalimab and from the mid-single digits to teens for nofazinlimab, subject to potential reduction following the launch of certain generic products. The royalties for sugemalimab and nofazinlimab will expire on a product-by-product and country-by-country basis upon the later to occur of (i) the expiration of all valid patent claims

Table of Contents

covering the compounds in a country, (ii) the expiration of all regulatory exclusivities for sugemalimab and nofazinlimab in a country, or (iii) 11 years following the first commercial sale of sugemalimab or nofazinlimab in a country.

The Company is responsible for the costs associated with the development and regulatory approvals of sugemalimab and nofazinlimab in its territory. The Company is also required to reimburse CStone for any costs it incurs in the Company's territory following the execution of the license agreement for development activities that were ongoing at the time the license agreement became effective. Additionally, during the term of the license agreement, either party may propose the development of a combination study with sugemalimab or nofazinlimab. If both parties agree to participate in the combination study, the costs incurred will be split between the two parties based upon the terms provided for in a separate written agreement detailing each party's rights and obligations with respect to the development of the combination regimen.

The Company has the right to terminate the license agreement with CStone for any or no reason upon providing prior written notice to CStone. Either party may terminate the license agreement in its entirety for the other party's material breach if such party fails to cure the breach. Either party may also terminate the agreement in its entirety upon certain insolvency events involving the other party.

The Company evaluated the license agreement with CStone under ASC 805 and concluded that the transaction did not meet the requirements to be accounted for as a business combination and therefore was accounted for as an asset acquisition.

Other Licenses

The Company has entered into a number of license agreements under which it acquired exclusive licenses for the research, development and commercialization of preclinical and clinical compounds from pharmaceutical and/or biotechnology companies (the "Preclinical/Clinical Assets").

Under the terms of the license agreements executed, the Company received exclusive licenses to develop the Preclinical/Clinical Assets at its own cost and expense in the Company's territory. The Company was obligated to make upfront non-refundable, non-creditable payments of $31.5 million through March 31, 2022. If the Company succeeds in developing and commercializing the Preclinical/Clinical Assets, the Company may be required to pay (i) up to $108.0 million in development milestone payments, (ii) up to $243.0 million in regulatory milestone payments, and (iii) up to $1.0 billion in sales milestone payments. Additionally, the Company may be required to pay royalties on worldwide net sales of any products containing the Preclinical/Clinical Assets which range from mid-single digits to low double digits, subject to potential reduction following the launch of certain generic products. The royalties for the Preclinical/Clinical Assets will expire on a product-by-product and country-by-country basis.

The Company has the right to terminate the license agreements for the Preclinical/Clinical Assets for any or no reason with prior written notice, and either party may terminate the license agreements in their entirety for the other party's material breach if such party fails to cure the breach. Either party may also terminate the agreements in its entirety upon certain insolvency events involving the other party. During the three months ended March 31, 2022, the Company sent notices of termination for two preclinical license agreements that will be effective in May 2022.

The Company evaluated the license agreements under ASC 805 and concluded that because the fair value of the gross assets acquired under each license agreement is concentrated in a single identifiable asset or group of similar assets, the transactions did not meet the requirements to be accounted for as a business combination and therefore were accounted for as asset acquisitions.

Discovery Collaboration Agreements

The Company has entered into a number of discovery collaboration agreements pursuant to which the Company agreed to collaborate with certain collaboration partners (the "Partners"), leveraging the Partner's AI capabilities to identify, discover and develop innovative therapeutics for agreed upon targets, in order to further expand the Company's pipeline of therapies (the "Collaboration Agreements").

Pursuant to the Collaboration Agreements, the parties will collaborate to identify a number of targets for which the parties will seek to develop candidates to treat patients. In general, the Partners are responsible for performing the discovery, profiling, preclinical and investigational new drug application ("IND") enabling studies (the "Research Activities") for all potential candidates. Once a candidate is identified and selected for further development (the "Collaboration Product"), the Company is generally responsible for all activities required to develop and commercialize the Collaboration Product. In general, the Company and the Partners will equally share costs (including research, development, and commercialization) and profits (losses) with respect to each Collaboration Product.

All activities performed under the Collaboration Agreements are overseen by joint steering committees established under each Collaboration Agreement and made up of an equal number of participants from the Partner and the Company. Decisions by the joint steering committee will generally be made by consensus.

The terms of the Collaboration Agreements will continue throughout the development and commercialization of the Collaboration Products, on a product-by-product basis, until the expiration of the last payment obligation by one of the parties to the other or, if earlier terminated. The Company has the right to terminate the Collaboration Agreements for any or no reason upon providing prior written notice.

The Collaboration Agreements are considered to be within the scope of ASC 808 as the agreements represent a joint operating activity and both the Partners and the Company are active participants and exposed to the risks and rewards. The Company has evaluated the Collaboration Agreements and determined they do not fall within the scope of ASC 606 as the Partners do not meet the definition of a customer. Through March 31, 2022, the Company has paid upfront fees totalling $32.5 million under the Collaboration Agreements, of which $17.0 million and $8.5 million are reflected in prepaid and other current assets and other non-current assets, respectively, on the condensed consolidated balance sheet at March 31, 2022.

13. COMMITMENT AND CONTINGENCIES

Operating Leases

In December 2019, the Company entered into a non-cancellable operating lease with Surface Oncology, Inc. ("Surface") for 33,529 square feet of office space in Cambridge, Massachusetts (the "Lease Agreement"). The term of the Lease Agreement originally commenced on January 1, 2020, and was set to expire on January 31, 2023 (the "Original Term Date"), with no renewal option. On May 11, 2022, the Company entered into an amendment to the Lease Agreement (the "Amended Lease Agreement") that extended to lease expiration date to July 31, 2024, and provided the Company with an option to further extend the lease expiration date to January 31, 2025 if Surface does not provide written notice on or before September 30, 2023 that it will retake possession of the premises on July 31, 2024.

Pursuant to the Lease Agreement, the Company will pay an initial annual base rent of $2.5 million, which base rent increases after every twelve-month period during the lease term to $2.7 million for the last twelve-month period (the "Base Rent"). Pursuant to the Amended Lease Agreement, the Base Rent decreases subsequent to the Original Term Date to an equivalent of an annual base rent of approximately $2.5 million. The Company has also agreed to pay its proportionate share of operating expenses and property taxes for the building in which the leased space is located. The Lease Agreement provided the Company with an improvement allowance of up to $1.0 million. Upon payment to the Company of the improvement allowance, the Lease

Table of Contents

Agreement provided that the annual Base Rent would be increased by the total amount drawn and amortized on a straight-line basis over the balance of the lease term such that the full amount of the allowance drawn would be reimbursed to Surface as of the last regularly scheduled Base Rent payment date.

During the year ended December 31, 2020, the Company completed a buildout of the leased office space and received the $1.0 million improvement allowance from Surface in January 2021. The Company determined that it owns the leasehold improvements and, as such, reflected the $1.0 million leasehold improvement as property and equipment in the consolidated balance sheet.

The following table summarizes the effect of lease costs in the Company's consolidated statements of operations and comprehensive (in thousands):

The Company made cash payments of $1.0 million and $1.0 million under the Lease Agreement during the three months ended March 31, 2022 and 2021, respectively.

Legal Proceedings

From time to time, the Company may become subject to legal proceedings and claims which arise in the ordinary course of its business. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable, and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

As of March 31, 2022, the Company was not party to any material litigation.

​

​

14. INCOME TAXES

There has historically been no federal or state provision for income taxes because the Company has incurred operating losses and maintains a full valuation allowance against its net deferred tax assets and liabilities in the United States. For the three months ended March 31, 2022 and 2021, the Company recognized no provision for income taxes in the United States. The foreign provision for income taxes was immaterial for the three months ended March 31, 2022 and 2021.

​

Utilization of net operating loss carryforwards, tax credits and other attributes may be subject to future annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions.

15. EMPLOYEE BENEFITS

In July 2020, the Company adopted a 401(k) retirement and savings plan (the "401(k) Plan") covering all employees. The 401(k) plan allows employees to make pre-tax or post-tax contributions up to the maximum allowable amount set by the Internal Revenue Services. Under the 401(k) Plan, the Company may make discretionary contributions as approved by the board of directors. The Company made contributions to the 401(k) Plan of approximately $0.5 million and $0.2 million during the three months ended March 31, 2022 and 2021, respectively.

​

16. NET INCOME (LOSS) PER SHARE

The Company computes basic and diluted earnings per share amounts based upon net income (loss) for the periods presented. Basic net income (loss) per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the sum of the weighted average number of common shares outstanding during the period including the effect of outstanding dilutive securities.

The Company applies the two-class method to calculate its basic and diluted net income (loss) per share as the Company has issued shares of restricted Common Stock that meet the definition of participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. The Company's participating securities contractually entitle the holders of such shares to participate in dividends; but do not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, diluted net loss per share is the same as basic net loss per share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands, except share and per share data):

​

The Company's potentially dilutive securities include Warrants, Earn-Out Shares, options to purchase Common Stock and unvested restricted Common Stock. These potentially dilutive securities have been excluded from

The Company excluded the following potential shares of Common Stock, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect:

The following discussion contains forward-looking statements that involve risks and uncertainties. See the section under the heading "Cautionary Note Regarding Forward-Looking Statements." Our actual results and the timing of certain events could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those discussed below and as set forth under "Risk Factors" in Part I, Item 1.A. of our Annual Report for the year ended December 31, 2021 as filed with the SEC on March 23, 2022, or the 2021 Annual Report. You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q, as well as our consolidated financial statements and accompanying notes thereto included in the 2021 Annual Report.

Overview

We are a new type of pharmaceutical company committed to developing and delivering innovative medicines to patients at radically lower prices. Our mission is to improve health for all with great, innovative, affordable medicines so that people with life-changing or chronic conditions can gain access to the medicines they need, physicians can treat patients without barriers to prescribing, and health systems can afford to make those medicines available, without restrictions, to the populations they serve in a financially sustainable manner. Launched in January 2020, our "New Pharma" solution starts with assembling a catalog of medicines at significant scale, targeting some of the most innovative clinical opportunities and highest drug cost categories of today and tomorrow, with an initial focus on oncology and immune-inflammatory diseases. We are focused on developing programs that are innovative, branded, and patent-protected that, if approved, have potential to be equivalent or superior to other therapies in their class. However, there is no guarantee our product candidates will be equivalent or superior to such other therapies. We do not currently have, and may never have, any products approved for commercial sale and have not generated any revenue to date, and may never become profitable. In addition, our business and pricing model is untested and may never be successful or generate sufficient revenue to lead to profitability.

Our team of leading drug hunters is building our catalog through:

Our initial focus has been in oncology and immune-inflammatory diseases, and includes both small molecules and biologics, with five clinical-stage programs, and several undisclosed preclinical and drug engineering programs. Our late-stage programs, each acquired in 2020, include: aumolertinib (EQ143), a third-generation epidermal growth factor receptor (EGFR) inhibitor, in-licensed from (Shanghai) Healthtech Co., LTD and Jiangsu Hansoh Pharmaceutical Group Company LTD (collectively, Hansoh), and sugemalimab (EQ165, also known as CS1001), an anti-programmed death-ligand 1 (PD-L1) antibody, in-licensed from CStone Pharmaceuticals (CStone).

Table of Contents

Our vision is to continue to grow our catalog of medicines in development through a mix of in-licensing, drug engineering collaborations and working with partners that will use our drugs and drug candidates in combination with their experimental medicines. However, the drug development process is inherently uncertain, and there can be no guarantee that that we will identify suitable assets to scale our portfolio and even if we do, we may not be able to acquire these assets or develop them successfully to achieve our targets. Further, our preclinical and early-stage discovery programs may not ever result in clinical development candidates. Additionally, our catalog of medicines and areas of focus may change as we further the development of our current programs and identify new targets which meet the criteria for inclusion in our portfolio. We have recently decided to de-prioritize our efforts to develop EQ121 for the treatment of rheumatoid arthritis, but will continue to evaluate EQ121 for the treatment of atopic dermatitis and other immune-inflammatory indications.

Assuming we are successful in obtaining regulatory approval, we plan to offer our catalog of innovative medicines to payers and health systems at radically lower prices, through a simple and transparent pricing model without surprise price increases. We are also assembling a Global Buyers Club by entering into long-term, trusted strategic partnerships with private and public payers, providers and health systems so they and the patients they serve can gain access to our, if approved, equally as good or better medicines at radically lower prices. We plan to offer simple and transparent pricing models to provide an opportunity for dramatic savings in these high-cost drug areas.

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 of the Business Combination, 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

Table of Contents

Class A common stock pursuant to the Merger Agreement. The newly combined business now operates under the Legacy EQRx management team.

Since our inception, we have focused primarily on organizing and staffing our company, business planning, raising capital, acquiring product candidates, securing related intellectual property, establishing strategic collaborations with payers, integrated delivery networks and health systems, and conducting research and development activities for our programs. Since our inception, we have funded our operations primarily through private equity financings. To date, we have raised an aggregate of approximately $2.2 billion of gross proceeds from the sale of our convertible preferred shares, convertible preferred notes that were issued in 2019 and subsequently converted into shares of our Series A convertible preferred stock (Series A), and our merger with CMLS III and associated PIPE financing

Since our inception, we have incurred significant operating losses. Our operating losses were $85.7 million and $27.0 million for the three months ended March 31, 2022 and 2021, respectively. We had an accumulated deficit of $337.8 million as of March 31, 2022. We expect to continue to incur significant and increasing 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 hire additional 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 expansion 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 successfully obtain regulatory approval for our product candidates, if ever, and as appropriate, complete clinical development. In addition, if we obtain regulatory approval for our product candidates, we expect to incur significant expenses related to developing our commercialization capabilities to support product sales, manufacturing and distribution activities. As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. 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 Ongoing COVID-19 Pandemic

In March 2020, the World Health Organization characterized the novel COVID-19 virus as a global pandemic. 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 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 adapting to evolving federal, state and local health regulations as they evolve. 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 entity'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 (Earn-Out Service Providers) may receive a pro rata share of up to 35,000,000 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 15,000,000 additional share 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 is treated as the "acquired" company for financial reporting purposes. This determination is primarily based on the fact that subsequent to the merger, Legacy EQRx stockholders have a majority of the voting power of the combined company, Legacy EQRx operations comprise all of the ongoing operations of the combined entity, Legacy EQRx governing body comprises a majority of the governing body of the combined company, and Legacy EQRx senior management comprises all of the senior management of the combined company.

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 our products through license 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:

27

Table of Contents

We expense research and development costs as they are incurred. We estimate preclinical study and clinical trial expenses based on the services performed pursuant to contracts with research institutions, CROs, and clinical manufacturing organizations (CMOs), that conduct and manage preclinical studies and clinical trials on our behalf based on actual time and expenses incurred by them. Further, we accrue expenses related to clinical trials based on the level of patient activity according to the related agreement. We monitor patient enrollment levels and related activity to the extent reasonably possible and adjust estimates accordingly.

We account for non-refundable advance payments for goods and services that will be used in future research and development activities as expenses when the services have been performed or when the goods have been received rather than when the payment is made.

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 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.

The following table summarizes our research and development expenses (in thousands):

​

​

The successful development of our product candidates is highly uncertain. We plan to substantially increase our research and development expenses for the foreseeable future as we continue the development of our product candidates and manufacturing processes, conduct discovery and research activities for our preclinical programs and expand our pipeline. 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

Table of Contents

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. Our clinical development costs are expected to increase significantly as we commence additional clinical trials. We anticipate that our expenses will increase substantially, particularly due to the numerous risks and uncertainties associated with developing product candidates, including the uncertainty of:

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. For example, if the U.S. Food and Drug Administration, European Medicines Agency, Medicines and Healthcare products Regulatory Agency or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate.

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, integrated delivery networks and health systems, as well as facility costs not otherwise included in research and development expenses, insurance and other general administrative expenses.

29

Table of Contents

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates. We also anticipate that we will incur significantly increased 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 pre-registrational programs, or any of our other product candidates, we expect to incur additional expenses related to the building of our team to support product sales and distribution activities.

Results of Operations

Comparison of the Three Months Ended March 31, 2022 and 2021

The following table summarizes our results of operations for the three months ended March 31, 2022 and 2021 (in thousands):

Table of Contents

Research and Development Expenses

Research and development expenses were $53.4 million for the three months ended March 31, 2022, compared to $16.7 million for the three months ended March 31, 2021. The increase of $36.8 million was primarily driven by a $18.3 million increase in discovery, preclinical and clinical development costs, a $9.9 million increase in employee related expenses driven by significant growth in our research and development headcount to support the development of our pipeline, a $4.5 million increase in information technology, facilities and other allocated expenses that support our overall research and development activities, a $2.1 million increase in consulting and professional fees, and a $2.0 million increase in license and milestone fees.

General and Administrative Expenses

General and administrative expenses were $32.3 million for the three months ended March 31, 2022, compared to $10.3 million for the three months ended March 31, 2021. The increase of $22.0 million was primarily driven by a $14.7 million increase in employee related expenses driven by an increase in headcount to support the overall growth of the organization, a $5.2 million increase in consulting and professional fees, and a $2.1 million increase in information technology, facilities, overhead allocations and other expenses.

Other Income, Net

Total other income, net was $106.4 million for the three months ended March 31, 2022, compared to $0.1 million for the three months ended March 31, 2021. The increase of $106.3 million was primarily due to $101.8 million and $3.9 million of non-cash income related to the remeasurement of the contingent earn-out liability and warrant liabilities, respectively, as of March 31, 2022.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have generated recurring net operating losses. We have not yet commercialized any product and we do not expect to generate revenue from sales of any products until 2023, 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 March 31, 2022, we had cash, cash equivalents and restricted cash of $1.6 billion.

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 and cash equivalents on hand as of March 31, 2022 of $1.6 billion will enable us to fund our operating expenses and capital expenditure requirements into 2025, 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 longer than into 2025.

We expect to incur significant expenses and operating losses for the foreseeable future as we seek regulatory approval, advance our product candidates, pursue commercialization of any approved product candidates and advance other candidates in our pipeline through preclinical and clinical development. We expect that our research and development and general and administrative costs will increase in connection with our planned research and development and commercialization activities. 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:

Until such time, if ever, as we can 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. 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 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 set forth below (in thousands):

​

​

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 three months ended March 31, 2022, was $53.9 million, which was primarily attributable to operating expenses of $85.7 million, partially offset by $17.9 million cash provided by changes in our operating assets and liabilities, $12.9 million of stock-based compensation expense and $0.4 million of depreciation expense. The net cash provided by changes in our operating assets and liabilities of $17.9 million was primarily due to a $19.0 million increase in accrued expenses, partially offset by a $0.9 million increase in prepaid expense and other current assets and a $0.2 million decrease in accounts payable.

Cash used in operating activities for the three months ended March 31, 2021, was $23.5 million, which was primarily attributable to a net loss of $26.8 million and was partially offset by net cash provided by changes in our operating assets and liabilities of $1.3 million, $0.9 million of non-cash lease expense, $0.8 million of stock-based compensation expense, and $0.3 million of depreciation expense. The net cash provided of $1.3 million as a result of changes in our operating assets and liabilities was primarily due to a $1.0 million increase in accounts payable, and a $0.4 million increase in accrued expenses, partially offset by a $0.1 million increase in prepaid expenses and other assets.

Investing Activities

Cash used in investing activities for the three months ended March 31, 2022 and 2021 was less than $0.1 million, and consisted of purchases of property and equipment.

Financing Activities

Cash used in financing activities for the three months ended March 31, 2022 was $1.4 million, and consisted primarily of offering costs paid in connection with the Business Combination.

33

Table of Contents

Cash provided by financing activities for the three months ended March 31, 2021 was $71.3 million, and consisted of net proceeds from the sale and issuance of shares of Series B convertible preferred stock.

Critical Accounting Policies and Significant Judgments and Estimates

Our condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of these condensed 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.

For a discussion of our critical accounting estimates, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" and notes to the financial statements in the 2021 Annual Report. There have been no material changes to these critical accounting policies and estimates through March 31, 2022 from those discussed in the 2021 Annual Report.

Emerging Growth Company Status

We are an "emerging growth company" (EGC) under the Jumpstart Our Business Startups Act of 2012 (the JOBS Act). Section 107 of the JOBS Act provides that an EGC can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. Thus, an EGC can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of delayed adoption of new or revised accounting standards and, therefore, we will be subject to the same requirements to adopt new or revised accounting standards as private entities. As an EGC, we may take advantage of certain exemptions and reduced reporting requirements under the JOBS Act. Subject to certain conditions, as an EGC:

We will remain an EGC until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the completion of the CMLS III initial public offering, (ii) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more, (iii) the date on which we have issued more than $1.0 billion in non-convertible debt during the previous rolling three-year period, or (iv) the date on which we are deemed to be a large accelerated filer under the Securities Exchange Act of 1934, as amended (the Exchange Act).

​

ITEM 3. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates.

34

Table of Contents

Interest Rate Risk

We had cash, cash equivalents and restricted cash of $1.6 billion and $1.7 billion as of March 31, 2022 and December 31, 2021, respectively, which consisted of cash, U.S. government money market funds, commercial paper and U.S. treasury bills. Interest income is sensitive to changes in the general level of interest rates; however, due to the nature of these investments, an immediate 1% change in interest rates would not have a material effect on the fair market value of our investment portfolio.

Foreign Currency Exchange Risk

We are exposed to market risk from changes in foreign currency exchange rates primarily in connection with our foreign subsidiary. Any transaction denominated in a currency other than the U.S. Dollar is reported in U.S. Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end of the applicable fiscal reporting period, and all revenues and expenses are translated at average rates for the period. The cumulative translation effect is included in equity as a component of accumulated other comprehensive income.

We currently do not have significant exposure to foreign currencies; however, our operations may be subject to fluctuations in foreign currency exchange rates in the future.

Effects of Inflation

We do not believe that inflation has had a material effect on our business, financial condition or results of operations. Our operations may be subject to inflation in the future.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures" as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, who serve as our principal executive officer and principal financial officer, respectively, has evaluated the effectiveness of our disclosure controls and procedures as of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2022.

Changes in Internal Control over Financial Reporting

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

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are probable to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on our business, financial condition, results of operations and prospects because of defense and settlement costs, diversion of management resources and other factors.

​

In connection with the Business Combination, on September 30, 2021, a putative stockholder of CMLS III, Anthony Franchi, filed a lawsuit naming CMLS III and certain of its directors in the Delaware Court of Chancery, captioned Franchi v. CM Life Sciences III Inc., CA No. 2021- 0842. The complaint alleged that the holders of CMLS III Class A common stock had been denied a right to vote as a separate class on a proposed amendment to CMLS III's charter to increase the authorized shares of Class A common stock (the Charter Amendment Proposal). The complaint asserted claims for violation of Section 242(b)(2) of the Delaware General Corporations Law and for breach of fiduciary duty against certain of the director defendants. The complaint sought preliminary and final injunctive relief enjoining the vote on the Charter Amendment Proposal, damages, and the costs and expenses of the litigation, including a reasonable allowance of fees and costs for plaintiff's attorneys, along with other relief. On October 18, 2021, the plaintiff filed a motion for preliminary injunction seeking to enjoin the CMLS III stockholder vote on the Charter Amendment Proposal. On October 29, 2021, the merger agreement was amended to add a provision requiring the affirmative vote of the holders of a majority of the shares of CMS III Class A common stock then outstanding and entitled to vote thereon, voting separately as a single series, for the Charter Amendment Proposal.
