NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. Nature of the Business IMARA Inc. (“IMARA” or the “Company”) is a clinical-stage biopharmaceutical company dedicated to developing and commercializing novel therapeutics to treat rare inherited genetic disorders of hemoglobin, known as hemoglobinopathies, which have significant unmet medical need. The Company was incorporated in January 2016 under the laws of the State of Delaware, and its principal offices are in Boston, Massachusetts. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including but not limited to, risks associated with completing preclinical studies and clinical trials, receiving regulatory approvals for product candidates, development by competitors of new biopharmaceutical products, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. The Company’s lead product candidate currently under development, t ovinontrine (IMR-687), as well as any other product candidates the Company may develop, will require significant additional 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-reporting capabilities. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize revenue from product sales. In February 2020, the Company effected a 1-for-6.299 reverse stock split of the Company’s issued and outstanding shares of common stock and a proportional adjustment to the existing conversion ratios for each of the Company’s outstanding series of preferred stock. All share and per share amounts in the unaudited condensed consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the reverse stock split, including reclassifying an amount equal to the change in par value of common stock to additional paid-in capital. On February 25, 2020, the Company issued and sold 1,562,994 ‬ shares of Series B convertible preferred stock (“Series B Preferred Stock”), at a price of $ 10.9722 per share, upon a waiver of specified milestone conditions from the holders of a majority of the shares then held by holders of Series B Preferred Stock, and raised approximately $ 17.1 million in net proceeds after deducting less than $ 0.1 million of issuance costs. On March 16, 2020, the Company completed an initial public offering (“IPO”) of its common stock and issued and sold 4,700,000 shares of common stock at a public offering price of $ 16.00 per share, resulting in gross proceeds of $ 75.2 million. On April 13, 2020, the Company issued and sold an additional 705,000 shares of common stock pursuant to the exercise of the underwriters’ option to purchase additional shares for aggregate gross proceeds of $ 11.3 million. Inclusive of the exercise by the underwriters of their option to purchase additional shares, the Company received approximately $ 76.5 million in net proceeds from the IPO after deducting $ 10.0 million of underwriting discounts and commissions and offering expenses. Upon the closing of the IPO, all 70,378,661 shares of outstanding preferred stock automatically converted into 11,172,955 shares of common stock. Upon conversion of the convertible preferred stock, the Company reclassified the carrying value of the convertible preferred stock to common stock and additional paid-in capital. On April 1, 2021, the Company filed a Registration Statement on Form S-3 (the “Shelf”) with the SEC in relation to the registration and potential future issuance of common stock, preferred stock, debt securities, warrants and/or units of any combination thereof in the aggregate amount of up to $ 200.0 million. The Shelf was declared effective on April 8, 2021. The Company also simultaneously entered into a sales agreement with Cantor Fitzgerald & Co, LLC, as sales agent, providing for the offering, issuance and sale by the Company of up to an aggregate $ 75.0 million of its common stock from time to time in “at-the-market” offerings under the Shelf. As of September 30, 2021, the Company had issued and sold 231,291 shares of common stock under the sales agreement, resulting in net proceeds of $ 1.5 million after deducting commissions and offering expenses. On July 16, 2021, the Company completed a public offering of shares of its common stock. In connection with the offering, the Company issued and sold 8,333,333 shares of common stock at a public offering price of $ 6.00 per share, resulting in net proceeds of $ 46.8 million after deducting underwriting discounts and commissions and offering expenses. Liquidity The Company has incurred recurring negative cash flows since inception and has funded its operations primarily from the sale of convertible preferred stock and proceeds from the IPO and subsequent common stock offerings. As of September 30, 2021, the 7 Company had cash, cash equivalents and investments of $ 102.8 million and an accumulated deficit of approximately $ 133.2 million. The Company expects its operating losses and negative operating cash flows to continue into the foreseeable future as it continues to expand its research and development efforts . The Company believes its cash, cash equivalents and investments as of September 30, 2021 will be sufficient to fund its operating expenses and capital expenditure requirements for at least twelve months from the date of filing this Quarterly Report on Form 10-Q. The Company will need additional funding to support its planned operating activities. There can be no assurances, however, that the current operating plan will be achieved or that additional funding will be available on terms acceptable to the Company, or at all. If the Company is unable to obtain sufficient funding, it could be required to delay its development efforts, limit activities and reduce research and development costs, which could adversely affect its business prospects. 2. Summary of Significant Accounting Policies Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Updates of the Financial Accounting Standards Board (“FASB”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2020 and notes thereto, included in the Company’s Annual Report on Form 10-K (the “Annual Report”), filed with the SEC on March 5, 2021. The unaudited condensed consolidated interim financial statements have been prepared on the same basis as the audited financial statements, with the exception of the modified retrospective adoption of ASC 842 Leases. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated interim financial statements contain all adjustments which are necessary to present fairly the Company’s financial position as of September 30, 2021, the results of its operations for the three and nine months ended September 30, 2021 and 2020 and cash flows for the nine months ended September 30, 2021 and 2020. Such adjustments are of a normal and recurring nature. The results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results for the year ending December 31, 2021, or for any future period. Principles of Consolidation The accompanying unaudited condensed consolidated financial statements of the Company include the accounts of its wholly owned subsidiaries, IMARA Security Corporation and IMARA E.U. Limited. All intercompany transactions and balances have been eliminated in consolidation. IMARA E.U. Limited was dissolved in July 2021 and the dissolution of the subsidiary did not have any material accounting implications on the Company’s unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2021. Summary of Significant Accounting Policies The significant accounting policies and estimates used in the preparation of the accompanying unaudited condensed consolidated financial statements are described in the Company’s audited consolidated financial statements for the year ended December 31, 2020 included in the Company’s Annual Report. There have been no material changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2021, with the exception of the modified retrospective adoption of ASC 842 Leases. Use of Estimates The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, accrued research and development expenses, stock-based compensation expense, the fair value of the common stock and the intrinsic value of the beneficial conversation feature present in the second tranche of the Series B Preferred Stock issued in February of 2020. Actual results could differ materially from those estimates. 8 Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). This standard established a right-of-use model that requires all lessees to recognize right-of-use assets and lease liabilities on their balance sheet that arise from leases as well as provide disclosures with respect to certain qualitative and quantitative information related to a company’s leasing arrangements to meet the objective of allowing users of financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. The FASB subsequently issued the following amendments to ASU 2016-02 that have the same effective date and transition date: ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842, ASU No. 2018-10, Codification Improvements to Topic 842, Leases, ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, ASU No. 2018-20, Narrow-Scope Improvement for Lessors, and ASU No. 2019-01, Leases (Topic 842): Codification Improvements. The Company early adopted these amendments with ASU 2016-02 (collectively, the “new leasing standards”), effective January 1, 2021. The Company adopted the new leasing standards using the modified retrospective transition approach, with no restatement of prior periods and there was no cumulative adjustment to retained earnings. Upon adoption, the Company elected the package of transition practical expedients, which allowed the Company to not reassess the following: (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) the treatment of initial direct costs for existing leases. The Company made an accounting policy election to not recognize short-term leases with an initial term of twelve months or less within its consolidated balance sheets and to recognize those lease payments on a straight-line basis in its consolidated statements of operations over the lease term. Upon adopting the new leasing standards, the Company recognized an operating lease right-of-use asset of $ 0.7 million and a corresponding current and non-current operating lease liability of $ 0.3 million and $ 0.6 million, respectively, which are included in its consolidated balance sheets. The adoption of the new leasing standards did not have a material impact on the Company’s consolidated statements of operations. The Company determines if an arrangement is a lease at contract inception. Operating lease right-of-use assets represent the Company’s right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating right-of-use assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over the lease term. When determining the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The Company uses the implicit rate when readily determinable and uses its incremental borrowing rate when the implicit rate is not readily determinable, based upon the information available at the commencement date in determining the present value of the lease payments. The incremental borrowing rate is determined using a secured borrowing rate for the same currency and term as the associated lease. The lease payments used to determine operating lease right-of-use assets may include lease incentives and stated rent increases. The Company’s lease agreements may include both lease and non-lease components, which the Company accounts for as a single lease component when the payments are fixed, for all classes of underlying assets. Variable payments included in the lease agreement are expensed as incurred. The Company’s operating leases are reflected in operating lease right-of-use assets and in current operating lease liabilities and long-term operating lease liabilities in its consolidated balance sheets. The Company’s operating lease right-of-use asset as of September 30, 2021 did not include any material lease incentives. Lease expense for future lease payments is recognized on a straight-line basis over the lease term. Prior to the adoption of the new leasing standards, the Company recognized lease costs on a straight-line basis once it gained control of the space, without regard to deferred payment terms, such as rent holidays, that would defer the commencement date of required payments or escalating payment amounts. Any lease incentives received were treated as a reduction of costs over the term of the lease agreement, as they were considered an inseparable part of the lease agreement. The difference between required lease payments and rent expense was recorded as deferred rent, which was reflected as deferred rent in the December 31, 2020 consolidated balance sheet. Segments Operating segments are defined as components of an enterprise for which separate and discrete information is available for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The Company has one operating segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s operations on a consolidated basis for the purpose of allocating resources. All of the Company’s long-lived assets are held in the United States. Deferred Offering Costs The Company capitalizes certain legal, professional, accounting and other third-party fees that are directly associated with in-process equity issuances as deferred offering costs until such equity issuances are consummated. After consummation of the equity 9 issuance, these costs are recorded as a reduction in the capitalized amount associated with the equity issuance. Should the equity issuance be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the unaudited condensed consolidated statement of operations and comprehensive loss. There were no deferred offering costs as of September 30, 2021 and December 31, 2020 . Comprehensive Loss Comprehensive loss includes net loss and certain changes in stockholders’ equity that are excluded from net loss. The Company’s comprehensive loss includes unrealized losses on available-for-sale debt securities for the three and nine months ended September 30, 2021 and 2020. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-02 supersedes the previous leases standard, ASC 840, Leases. For additional information on the adoption of the new leasing standards, please read the Company’s policy above entitled Leases, and Note 7, Commitments and Contingencies, to these condensed consolidated financial statements. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815) I. Accounting for Certain Financial Instruments with Down Round Features II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception (“ASU 2017-11”). Part I applies to entities that issue financial instruments such as warrants, convertible debt or convertible preferred stock that contain down-round features. Part II replaces the indefinite deferral for certain mandatorily redeemable noncontrolling interests and mandatorily redeemable financial instruments of nonpublic entities contained within ASC Topic 480 with a scope exception and does not impact the accounting for these mandatorily redeemable instruments. For public entities, the amendments in Part I of this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For all other entities, the amendments in Part I of this update are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including adoption in an interim period. The adoption had no material impact on the Company’s financial position, results of operations or cash flows. The amendments in Part II of this update do not require any transition guidance because those amendments do not have an accounting effect. In March 2020, the FASB issued “ASU 2020-03”, Codification Improvements to Financial Instruments, (“ASU 2020-03”) which addressed, among other topics, Amendments related to ASU 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13”). The amendments align the contractual term under Topic 326 and Topic 842 (Leases) to be consistent, and also clarifies when an entity should record an allowance for credit losses in accordance with Topic 326. For public business entities that meet the definition of a SEC filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, the standard is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. For all other entities, the standard is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted.

Fair Value of Financial Assets and Liabilities The following table presents information about the Company’s financial assets and liabilities measured at fair value on a recurring basis and indicates the level of the fair value hierarchy utilized to determine such fair values (in thousands): September 30, 2021 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Observable Inputs Description Total (Level 1) (Level 2) (Level 3) Assets: Money market funds, included in cash and cash equivalents $ 64,223 $ 64,223 $ — $ — Marketable securities: Corporate debt securities 4,501 — 4,501 — Commercial paper 23,043 — 23,043 — Total financial assets $ 91,767 $ 64,223 $ 27,544 $ — December 31, 2020 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Observable Inputs Description Total (Level 1) (Level 2) (Level 3) Assets: Money market funds, included in cash and cash equivalents $ 41,208 $ 41,208 $ — $ — Marketable securities: Corporate debt securities 14,807 — 14,807 — Commercial paper 25,717 — 25,717 — Total financial assets $ 81,732 $ 41,208 $ 40,524 $ — As of September 30, 2021 and December 31, 2020, the Company’s Level 1 financial assets consisted of cash equivalents held in money market funds, which are valued using quoted market prices in active markets without any valuation adjustment. The financial assets valued based on Level 2 inputs consist of corporate debt securities and commercial paper, which consist of investments in highly-rated investment-grade securities. The Company estimates the fair values of these marketable securities by taking into consideration valuations obtained from third-party pricing sources. These pricing sources utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include market pricing based on real-time trade data for the same or similar securities, issuer credit spreads, benchmark yields, and other observable inputs. The Company validates the prices provided by its third-party pricing sources by understanding the models used, obtaining market values from other pricing sources and analyzing pricing data in certain instances. During the three and nine months ended September 30, 2021 and the year ended December 31, 2020, there were no transfers between fair value measurement levels. The carrying values of other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. 11 4. Investments As of September 30, 2021 and December 31, 2020, the Company had short-term investments consisting of corporate debt securities and commercial paper, which are considered to be available-for-sale investments. These are included in short-term investments on the condensed consolidated balance sheets, even though the stated maturity date may be one year or more beyond the current balance sheet date, as the Company views those securities as available for use in current operations, if needed. The following table summarizes the Company’s investments (in thousands): September 30, 2021 Amortized Cost Gross Unrealized Gains Gross Unrealized Loss Fair Value Current: Commercial paper $ 23,043 $ — $ — $ 23,043 Corporate debt securities 4,503 — ( 2 ) $ 4,501 Total $ 27,546 $ — $ ( 2 ) $ 27,544 December 31, 2020 Amortized Cost Gross Unrealized Gains Gross Unrealized Loss Fair Value Current: Commercial paper $ 25,716 $ 1 $ — $ 25,717 Corporate debt securities 14,804 3 — 14,807 Total $ 40,520 $ 4 $ — $ 40,524 As of September 30, 2021, the Company held two available-for-sale securities with an aggregate value of approximately $ 4.5 million in an unrealized loss position for less than twelve months. As of December 31, 2020, the Company had no available-for-sale securities in unrealized loss positions. The Company has the intent and ability to hold such securities until recovery. The Company determined that there was no material change in the credit risk of these investments . As a result, the Company determined it did not hold any investments with an other-than-temporary impairment as of September 30, 2021 and December 31, 2020. 5. Accrued Expenses Accrued expenses consisted of the following (in thousands): September 30, 2021 December 31, 2020 Accrued research and development expenses $ 2,599 $ 2,732 Accrued compensation and benefits 1,564 1,090 Accrued professional services 272 355 Accrued other 27 99 Total accrued expenses $ 4,462 $ 4,276 6. License Agreements Agreement with Lundbeck In April 2016, the Company entered into a license agreement with Lundbeck A/S (“Lundbeck” and the “Lundbeck Agreement”) pursuant to which Lundbeck granted the Company the following licenses within the field of prevention, treatment or diagnosis of hemoglobinopathy disorders and/or other diseases or disorders, including those directly or indirectly related to hemoglobinopathies: (1) an exclusive, royalty-bearing license to certain patent rights and certain know-how owned or otherwise controlled by Lundbeck (“Licensed Technology”) to research, develop, make, use, sell, and commercialize products (“Licensed Products”) from PDE9 inhibitors, which included tovinontrine (“Licensed Compounds”); (2) a non-exclusive license to the Licensed Technology to make, research, develop, and use such Licensed Technology to enable research and development, with certain restrictions; and (3) a sublicensing right that allows the Company to grant sublicenses to third parties to use the Licensed Technology subject to the certain terms detailed in the Lundbeck Agreement. Under the Lundbeck Agreement, the Company is subject to certain achievement dates for development milestones as defined in the agreement. The regulatory milestones due under the Lundbeck Agreement depend on the products being developed. Development milestones due under the Lundbeck Agreement with respect to the Licensed Compounds total up to $ 23.5 million, and, for any products that contain PDE9 inhibitors other than Licensed Compounds, total up to $ 11.8 million. The Company also agreed to pay tiered royalties based on net sales of all products licensed under the agreement in the low single-digit percentages. 12 To date, pursuant to the Lundbeck Agreement, the Company has made cash payments to Lundbeck of $ 1.8 million consisting of an upfront payment and ongoing milestone payments, which were recorded as research and development expenses. No payments were made during the year ended December 31, 2020, or for the three and nine months ended September 30, 2021. As partial consideration for the license, the Company issued 167,523 shares of common stock to Lundbeck, which represented 8.0 % of the Company’s then outstanding equity pursuant to a restricted stock agreement. The shares were fully vested on the date of issuance. The Company also allowed Lundbeck to participate in the fourth tranche of its Series A preferred stock financing in November 2018 at $ 1.00 per share. The Lundbeck Agreement can be terminated by the Company at any time with 180 days’ written notice. The Company or Lundbeck may terminate the agreement by written notice within a specified period of time in the event of a material breach. 7. Commitments and Contingencies Lease Agreements In 2016, the Company entered into an agreement for office space located in Cambridge, Massachusetts, which was a month-to-month lease. The agreement for this space terminated on August 17, 2019 . In May 2019, the Company entered into a new operating lease agreement (the “May 2019 Lease Agreement”) for office space totaling 4,210 square feet, located in Boston, Massachusetts with a 62 -month term. The lease includes a rent escalation clause which results in cash rental payments of approximately $ 0.3 million annually. Rent expense is being recognized on a straight-line basis over the lease term. In addition to the base rent, the Company is also responsible for its share of operating expenses, electricity and real estate taxes, in accordance with the terms of the May 2019 Lease Agreement. The Company provided a security deposit of approximately $ 0.1 million in May 2019, which is included as a component of other assets on the Company’s unaudited condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020. The Company occupied the space in August 2019 and commenced recognition of rent expense. The Company recorded rent expense of less than $ 0.1 million during the three months ended September 30, 2021, and approximately $ 0.2 million during the nine months ended September 30, 2021. In June 2021, the Company entered into an amendment to the May 2019 Lease Agreement (the “June 2021 Amended Lease Agreement”). Under the terms of the June 2021 Amended Lease Agreement, the Company will expand its current premises in Boston, Massachusetts by an additional 5,026 square feet, bringing the total office space to 9,236 square feet. The term of the June 2021 Amended Lease Agreement commences upon completion of the buildout of the additional space, which is expected to be on or about January 1, 2022 and expires on March 31, 2027 . The Company has the option to extend the term for one additional five-year period upon the Company’s written notice to the landlord at least 12 months and no more than 15 months in advance of the extension period. Upon commencement of the term of the June 2021 Amended Lease Agreement, the annual base rent obligation will be approximately $ 0.6 million, with a total cash obligation for base rent over the initial five-year term of the lease of approximately $ 3.8 million. In addition to the base rent, the Company is also responsible for its share of operating expenses, electricity and real estate taxes. Upon execution of the June 2021 Amended Lease Agreement, the Company provided an additional security deposit in the amount of $ 0.1 million, with security deposits under the May 2019 Lease Agreement and June 2021 Amended Lease Agreement totaling $ 0.2 million. The following table summarizes the future lease payments due under the May 2019 Lease Agreement only, as the term of the June 2021 Amended Lease Agreement has not yet commenced (in thousands): September 30, 2021 2021 $ 69 2022 278 2023 284 2024 229 Total Lease Payments $ 860 Less Imputed Interest ( 144 ) Present value of operating lease liabilities $ 716 Operating cash flows used for operating leases $ 203 Weighted-average remaining lease term (years) 3.08 Weighted-average discount rate 8 % 13 Under the prior lease accounting guidance, minimum rental commitments under non-cancelable leases as of December 31, 2020 were as follows (in thousands): Minimum Lease Payments 2021 273 2022 278 2023 284 2024 229 $ 1,064 Legal Proceedings The Company may from time to time be party to litigation arising in the ordinary course of business. The Company was not subject to any material legal proceedings during the three and nine months ended September 30, 2021 and year ended December 31, 2020, and no material legal proceedings are currently pending or, to the best of its knowledge, threatened. Indemnification Obligations The Company agrees to standard indemnification obligations as part of entering into agreements in the ordinary course of business. Pursuant to the indemnification provisions, the Company agrees to indemnify, hold harmless, and to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners, in connection with matters specified in the applicable provision, which may include any U.S. patent or any copyright or other intellectual property infringement claim by any third-party with respect to the Company’s products or product liability claims by any third-party with respect to the Company’s products. The term of these indemnification obligations is generally perpetual any time after execution of the agreement. The potential amount of future payments the Company could be required to make under these indemnification obligations is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification obligations. 8. Convertible Preferred Stock Prior to the sale of common stock in connection with its IPO, the Company had funded its operations primarily with proceeds from the sale of Preferred Stock. On February 25, 2020, the Company raised $ 17.1 million in net proceeds from the sale of 1,562,994 ‬ shares of Series B Preferred Stock, at a price of $ 10.9722 per share, upon a waiver of specified milestone conditions from the holders of a majority of the shares then held by the holders of Series B Preferred Stock. Upon issuance, each share of Series B Preferred Stock included an embedded beneficial conversion feature as the estimated fair value of the Company’s common stock on the date of issuance of the Series B Preferred Stock was higher than the effective conversion price of the Series B Preferred Stock of $ 10.9722 per share. Given the proximity of the issuance to the Company’s public offering, the Company utilized the $ 16.00 public offering price of its common stock to determine the intrinsic value of the beneficial conversion feature. As a result, the Company recorded the intrinsic value of the beneficial conversion feature of $ 7.9 million as a discount on the Series B Preferred Stock at issuance. Because the Series B Preferred Stock was immediately convertible upon issuance and did not include mandatory redemption provisions, the discount on the Series B Preferred Stock was immediately accreted. Upon the completion of the IPO on March 16, 2020, all 70,378,661 shares of outstanding preferred stock automatically converted into 11,172,955 shares of common stock. Prior to the conversion, the holders of the preferred stock were entitled to receive noncumulative dividends of 8 % per annum of the Series B issuance price only when and if declared by the Company’s board of directors. No dividends have been declared by the Company’s board of directors since inception. 9. Stockholders’ Equity On August 13, 2019, the Company’s board of directors, and on February 26, 2020, the Company’s stockholders, approved the Company’s restated certificate of incorporation, which became effective upon closing of the IPO on March 16, 2020, to authorize 10,000,000 shares of undesignated preferred stock, $ 0.001 per share par value, and to increase the number of authorized shares of common stock from 100,000,000 to 200,000,000 shares, $ 0.001 per share par value. 14 Common stockholders are entitled to receive dividends, as may be declared by the Board, if any, subject to the preferential dividend rights of any preferred stock then outstanding. Through September 30, 2021, no cash dividends have been declared or paid. As of September 30, 2021, 10,000,000 shares of preferred stock were authorized and no shares of preferred stock were issued or outstanding. As of September 30, 2021 and December 31, 2020, the Company has reserved for future issuance the following shares of common stock: September 30, 2021 December 31, 2020 Shares reserved for future issuance under the 2020 Equity Incentive Plan 1,276,472 1,110,675 Shares reserved for future issuance under the 2020 Employee Stock Purchase Plan 187,209 191,363 1,463,681 1,302,038 10. Stock-Based Compensation 2016 Stock Incentive Plan The Company’s 2016 Stock Incentive Plan, (the “2016 Plan”) provided for the grant of restricted stock, restricted stock units, stock appreciation rights, incentive stock options, non-statutory stock options and other stock-based awards to employees, officers, members of the Board, consultants and advisors of the Company. As of the effective date of the 2020 Equity Incentive Plan (the “2020 Plan”) on March 11, 2020, and as of September 30, 2021, no shares remained available for future issuance under the 2016 Plan. Any options or awards outstanding under the 2016 Plan remain outstanding and effective. 2020 Equity Incentive Plan On October 1, 2019, the Company’s board of directors adopted, and on February 26, 2020 the Company’s stockholders approved, the 2020 Plan, which became effective on March 11, 2020. The 2020 Plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. The number of shares reserved for issuance under the 2020 Plan is the sum of: (1) 1,220,283 shares of the Company’s common stock; plus (2) the number of shares (up to a maximum of 2,091,969 shares) equal to the sum of (x) 228,852 shares, which represents the Company’s common stock reserved for issuance under the 2016 Plan that remained available for grant under the 2016 Plan as of March 11, 2020 and (y) the number of shares of the Company’s common stock subject to outstanding awards granted under the 2016 Plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right. The number of shares reserved will be annually increased on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2021 and continuing until, and including, the fiscal year ending December 31, 2030, equal to the lesser of (i) 4 % of the number of shares of the Company’s common stock outstanding on the first day of such fiscal year and (ii) an amount determined by the Company’s board of directors. On January 1, 2021, 701,930 additional shares were reserved for issuance under the 2020 Plan pursuant to this provision. No more than 8,541,982 shares of common stock may be issued as incentive stock options under the 2020 Plan. The shares of common stock underlying any awards that expire, terminate, or are otherwise surrendered, cancelled, forfeited or repurchased by the Company under the 2016 Plan or the 2020 Plan will be added back to the shares of common stock available for issuance under the 2020 Plan. As of September 30, 2021, there were 1,276,472 shares available for future issuance under the 2020 Plan. For financial reporting purposes, the Company performed common stock valuations with the assistance of a third-party specialist through October 23, 2019 to determine stock-based compensation expense for stock options. Upon completion of the IPO, the fair value of the common stock on the grant date was based on the closing price of the stock on the Nasdaq Global Select Market on the date of grant. 15 The following table summarizes the Company’s stock option activity: Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding as of December 31, 2020 1,935,632 $ 9.85 8.14 $ 24,260 Granted 862,953 10.87 Exercised ( 158,681 ) 4.34 Forfeited ( 326,820 ) 14.75 Outstanding as of September 30, 2021 2,313,084 $ 9.92 8.39 $ 254 Options vested and exercisable as of September 30, 2021 764,726 $ 6.10 7.44 $ 206 The aggregate intrinsic value of options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the common stock as of the end of the period. The weighted-average grant date fair value of the Company’s stock options granted during the three and nine months ended September 30, 2021 was $ 3.66 and $ 7.44 , respectively. The weighted-average grant date fair value of the Company’s stock options granted during each of the three and nine months ended September 30, 2020 was $ 12.99 and $ 11.30 , respectively. Performance-based awards The Company granted stock options to purchase an aggregate of 220,928 shares of common stock to certain employees, officers and consultants and advisors of the Company on May 16, 2019, June 5, 2019 and September 21, 2019, which contained performance-based vesting criteria. Vesting of these options was contingent on the closing of the second tranche of Series B Preferred Stock financing. Stock-based compensation expense associated with performance-based stock options is recognized if the performance conditions are considered probable of being achieved, using management’s best estimates. As a result of the performance condition being met on February 25, 2020, these options vested as to 25 % of the shares underlying each option on February 25, 2021 and will vest as to the remainder of the shares in equal quarterly installments for three years thereafter. The Company recognized stock-based compensation expense of less than $ 0.1 million and $ 0.1 million for these options during the three and nine months ended September 30, 2021, respectively. Stock-Based Compensation Stock-based compensation expense included in the Company’s unaudited condensed consolidated statements of operations and comprehensive loss is as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Research and development $ 322 $ 161 $ 1,034 $ 501 General and administrative 681 481 1,833 1,051 Total stock-based compensation expense $ 1,003 $ 642 $ 2,867 $ 1,552 As of September 30, 2021 and December 31, 2020, total unrecognized compensation cost related to the unvested stock-based awards was $ 10.3 million and $ 9.5 million, respectively, which is expected to be recognized over a weighted-average period of 2.79 and 3.22 years, respectively. 2020 Employee Stock Purchase Plan On October 1, 2019, the Company’s board of directors adopted, and on February 26, 2020, the Company’s stockholders approved the 2020 Employee Stock Purchase Plan (the “2020 ESPP”), which became effective on March 11, 2020. The 2020 ESPP initially provides participating employees with the opportunity to purchase up to an aggregate of 193,216 shares of the Company’s common stock. The number of shares of the Company’s common stock reserved for issuance under the 2020 ESPP will automatically 16 increase on the first day of each fiscal year, beginning with the fiscal year commencing on January 1, 2021 and continuing until, and including, the fiscal year commencing on January 1, 2031, in an amount equal to the lowest of ( i ) 386,432 shares of the Company’s common stock, (ii) 1 % of the number of shares of the Company’s common stock outstanding on the first day of such fiscal year and (iii) an amount determined by the Company’s board of directors . The Company’s board of directors decided not to increase the number of shares of the Company’s common stock reserved for issuance under the 2020 ESPP for the 2021 fiscal year. During the nine months ended September 30, 2021, $ 0.1 million was withheld from employees, on an after-tax basis, in order to purchase 4,154 shares of the Company’s common stock. No shares were purchased during the three months ended September 30, 2021. The Company recorded stock-based compensation expense related to the 2020 ESPP of less than $ 0.1 million. As of September 30, 2021, 187,209 shares of the Company’s common stock remained available for issuance under the 2020 ESPP. As of September 30, 2021, there was less than $ 0.1 million of total unrecognized stock-based compensation expense related to the ESPP. The expense is expected to be recognized over a period of 2.5 months. 11. Income Taxes Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Due to the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against the Company’s otherwise recognizable net deferred tax assets. On March 27, 2020, the United States enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). The Cares Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act also established a Paycheck Protection Program whereby certain small businesses are eligible for a loan to fund payroll expenses, rent, and related costs. The CARES Act provided for an Employee Retention Credit (“ERC”), which is a refundable payroll tax credit that encouraged businesses to keep employees on the payroll during the COVID-19 pandemic. Eligible employers could qualify for up to $ 5,000 of credit for each employee based on certain wages paid after March 12, 2020 and before January 1, 2021. The ERC was subsequently amended by the Consolidated Appropriation Act (“CAA”) of 2021 and the American Rescue Plan Act (“ARPA”) of 2021. Under CAA and ARPA amendments, employers can claim a refundable tax credit against the employer share of social security tax equal to 70 % of the qualified wages (including certain health care expenses) paid to employees after December 31, 2020 through December 31, 2021. Qualified wages are limited to $ 10,000 per employee per calendar quarter in 2021 so the maximum ERTC available is $ 7,000 per employee per calendar quarter. Based on the Company’s evaluation of this provision and pandemic-related impact on its operations in 2020 and 2021, it was determined that the Company qualified to claim ERC in the second, third and fourth calendar quarters of 2020, as well as in both the first, second, and third calendar quarters of 2021. The Company recognized an ERC of approximately $ 0.3 million and $ 1.0 million as an offset to payroll tax expenses for the three and nine months ended September 30, 2021, respectively, in its consolidated statements of operations. The Company will continue to assess its eligibility to claim ERC for the fourth quarter of 2021. 12. Net Loss Per Share Basic and diluted net loss per share is determined by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding during the period. In 2020, the net loss applicable to common stockholders did not equal net loss due to the accretion of the beneficial conversion feature of Series B Preferred Stock in the amount of $ 7.9 million. The beneficial conversion feature was initially recorded as a discount on the Series B Preferred Stock with a corresponding amount recorded to Additional Paid-in Capital. The discount on the Series B Preferred Stock was then immediately written off as a deemed dividend as the Series B Preferred Stock does not have a stated redemption date and is immediately convertible at the option of the holder. The Company has computed diluted net loss per common share after giving consideration to all potentially dilutive common shares, including convertible preferred stock and options to purchase common stock during the period determined using the if-converted method, except where the effect of including such securities would be antidilutive. Because the Company has reported net losses since inception, these potential common shares have been anti-dilutive and basic and diluted loss per share have been the same. 17 The Company excluded the following potential common shares from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Options to purchase common stock 2,313,084 1,938,005 2,313,084 1,938,005 Shares reserved for future issuance under the ESPP 187,209 — 187,209 — 13.
