1. Nature of the business and basis of presentation Organization Beam Therapeutics Inc., which we refer to herein as the “Company” or “Beam,” is a biotechnology company committed to establishing the leading, fully integrated platform for precision genetic medicines. Beam’s vision is to provide life-long cures to patients suffering from genetic diseases. The Company was incorporated on January 25, 2017 as a Delaware corporation and began operations in July 2017. Its principal offices are in Cambridge, Massachusetts. Liquidity and capital resourcesSince its inception, the Company has devoted substantially all of its resources to building its base editing platform and advancing development of its portfolio of programs, establishing and protecting its intellectual property, conducting research and development activities, making arrangements to conduct manufacturing activities with contract manufacturing organizations, research and development costs including preclinical studies and IND-enabling studies, organizing and staffing the Company, maintaining its facilities and new facility build-outs, business planning, raising capital and providing general and administrative support for these operations. The Company has established internal manufacturing capabilities. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry including, but not limited to, technical risks associated with the successful research, development and manufacturing of product candidates, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.In April 2021, the Company entered into a sales agreement, or the Sales Agreement, with Jefferies, LLC, or Jefferies, pursuant to which the Company was entitled to offer and sell, from time to time at prevailing market prices, shares of the Company’s common stock having aggregate gross proceeds of up to $300.0 million. The Company agreed to pay Jefferies a commission of up to 3.0% of the aggregate gross sale proceeds of any shares sold by Jefferies under the Sales Agreement. As of December 31, 2023, the Company has sold 2,908,009 shares of its common stock under the Sales Agreement at an average price of $103.16 per share for aggregate gross proceeds of $300.0 million, before deducting commissions and offering expenses payable by the Company.In July 2021 and May 2023, the Company and Jefferies entered into amendments to the Sales Agreement to provide for increases in the aggregate offering amount under the Sales Agreement, such that as of May 10, 2023, the Company may offer and sell shares of common stock having an aggregate offering price of an additional $800.0 million. As of December 31, 2023, the Company has sold 10,860,992 additional shares of its common stock under the amended Sales Agreement at an average price of $51.93 per share for aggregate gross proceeds of $564.0 million, before deducting commissions and offering expenses payable by the Company, resulting in an aggregate of $864.0 million in gross proceeds received under the Sales Agreement, as amended, as of December 31, 2023.In October 2023, the Company entered into a Transfer and Delegation Agreement, or the Lilly Agreement, with Eli Lilly and Company, or Lilly, pursuant to which Lilly acquired certain assets and other rights under the Company’s amended collaboration and license agreement, or the Verve Agreement, with Verve Therapeutics, Inc., or Verve, including the Company’s opt-in rights to co-develop and co-commercialize Verve’s base editing programs for cardiovascular disease. The Company received a $200.0 million upfront payment and is eligible to receive up to $350.0 million in potential future development-stage payments upon the completion of certain clinical, regulatory and alliance events. In connection with the Lilly Agreement, the Company and Lilly entered into a Stock Purchase Agreement providing for the sale and issuance of 2,004,811 shares of the Company’s common stock to Lilly for an aggregate purchase price of $50.0 million. The Company received the consideration under the Stock Purchase Agreement of $50.0 million in October 2023 and the upfront payment of $200.0 million in November 2023. Since its inception, the Company has incurred substantial losses and had an accumulated deficit of $1.2 billion as of December 31, 2023. The Company expects to generate operating losses and negative operating cash flows for the foreseeable future.The Company expects that its cash, cash equivalents, and marketable securities as of December 31, 2023 of $1.2 billion will be sufficient to fund its operations for at least the next 12 months from the date of issuance of these financial statements. The Company will need additional financing to support its continuing operations and pursue its growth strategy. Until such time as the Company can generate significant revenue from product sales, if ever, it expects to finance its operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. The Company may be unable to raise additional funds or enter into such other agreements when needed on favorable terms or at all. The inability to raise capital as and when needed would have a negative impact on the Company’s financial condition and its ability to pursue its business strategy. The Company will need to generate significant revenue to achieve profitability, and it may never do so.

2. Summary of significant accounting policies <div style="font-size:10pt;font-family:Times New Roman;">Basis of presentation </div>The accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles, or GAAP. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification, or ASC, and Accounting Standards Update, or ASU, of the Financial Accounting Standards Board, or the FASB. <div style="font-size:10pt;font-family:Times New Roman;">Principles of consolidationThe accompanying consolidated financial statements include the results of operations of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. </div><div style="font-size:10pt;font-family:Times New Roman;">Use of estimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities as of and during the reporting period. The Company bases its estimates and assumptions on historical experience when available and on various factors that it believes to be reasonable under the circumstances. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, incremental borrowing rate used in the calculation of lease liabilities, research and development expenses, the fair values of common stock, stock-based compensation, contingent consideration liabilities, success payments, estimated license fees, contingent liabilities, and certain judgments regarding revenue recognition. Actual results could differ from these estimates.</div><div style="font-size:10pt;font-family:Times New Roman;">Cash, cash equivalents, and restricted cashCash and cash equivalents consist of checking accounts, money market accounts, and all highly liquid investments with a remaining maturity of three months or less at the date of purchase. Restricted cash represents collateral provided for letters of credit issued as security deposits in connection with the Company’s leases of its facilities.<div style="font-size:12pt;font-family:Times New Roman;">The following table reconciles cash, cash equivalents, and restricted cash reported within the Company’s consolidated balance sheets to the total of the amounts shown in the consolidated

#ffffff03;"> </td> </tr> </table> </div></div><div style="font-size:10pt;font-family:Times New Roman;">Marketable securitiesThe Company classifies marketable securities as available-for-sale. Available-for-sale securities consist of commercial paper, high-grade corporate notes, U.S. Treasury securities and government securities. Available-for-sale securities are carried at fair value with the unrealized gains and losses included in accumulated other comprehensive (loss) income as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income and/or expensed over the life of the instrument. Realized gains and losses are determined using the specific identification method and are included in interest and other income (expense), net.</div><div style="font-size:10pt;font-family:Times New Roman;">Corporate equity securitiesThe Company classifies investments in equity securities that have a readily determinable fair value as marketable securities in the Company's consolidated balance sheets. The Company’s marketable securities are stated at fair value. Typically, the fair value of these securities is based on a quoted price for an identical equity security. The Company held an investment in privately issued corporate equity securities, which were accounted for as investments in equity securities. This investment did not have a readily determinable fair value and the Company valued the investment based on the cost of the equity securities adjusted for observable market transactions or impairments, if any, and records any changes in value through earnings. The Company records changes in the fair value of its equity securities in other income (expense), net in its consolidated statements of operations and other comprehensive loss. </div><div style="font-size:10pt;font-family:Times New Roman;">Concentrations of credit risk </div>Financial instruments that are potentially subject to significant concentration of credit risk consist primarily of cash, cash equivalents, marketable securities, and restricted cash. The Company attempts to minimize the risk related to marketable securities by working with highly rated financial institutions that invest in a broad and diverse range of financial instruments. The Company has established guidelines relative to credit ratings and maturities intended to safeguard principal balances and maintain liquidity. The Company maintains its funds in accordance with its investment policy, which defines allowable investments, specifies credit quality standards and is designed to limit credit exposure to any single issuer. <div style="font-size:10pt;font-family:Times New Roman;">Guarantees and indemnifications As permitted under Delaware law, the Company indemnifies its officers, directors, consultants, and employees for certain events or occurrences that happen by reason of the relationship with, or position held at, the Company. For the years ended December 31, 2023, 2022 and 2021, the Company had not experienced any losses related to these indemnification obligations, and no claims were outstanding. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible, and no related reserves were established.</div><div style="font-size:10pt;font-family:Times New Roman;">Equity issuance costs The Company capitalizes incremental legal, professional, accounting and other third-party fees that were directly associated with its stock offerings as other non-current assets until the offerings are consummated. Upon consummation, these costs are recorded in stockholders’ equity as a reduction of additional paid-in-capital generated as a result of the offerings. As of December 31, 2023 and 2022, there were no deferred offering costs. </div><div style="font-size:12pt;font-family:Times New Roman;">Fair value of financial instruments ASC Topic 820, Fair Value Measurement, or ASC 820, establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the assets or liability and are developed based on the best information available in the circumstances. ASC 820 identifies fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tiered value hierarchy that distinguishes between the following: Level 1—Quoted market prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 inputs that are either directly or indirectly observable, such as quoted market prices, interest rates and yield curves. Level 3—Unobservable inputs for the asset or liability (i.e., supported by little or no market activity). Level 3 inputs include management’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair values requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized as Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. There have been no changes to the valuation methods utilized during the years ended December 31, 2023 and 2022. The Company evaluates transfers between levels at the end of each reporting period. </div><div style="font-size:10pt;font-family:Times New Roman;">Property and equipment <div style="font-size:10pt;font-family:Times New Roman;">Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful life of each asset as follows: <table style="margin-left:auto;border-spacing:0;table-layout:fixed;width:100.0%;border-collapse:separate;margin-right:auto;"> <tr style="visibility:collapse;"> <td style="width:49%;"></td> <td style="width:2%;"></td> <td style="width:49%;"></td> </tr> <tr style="height:8pt;word-break:break-word;white-space:pre-wrap;"> <td style="vertical-align:top;border-bottom:0.5pt solid;">Asset category</td> <td style="vertical-align:top;border-bottom:0.5pt solid #ffffff03;"> </td> <td style="vertical-align:top;border-bottom:0.5pt solid;">Estimated useful life</td> </tr> <tr style="height:10pt;word-break:break-word;white-space:pre-wrap;"> <td style="vertical-align:top;">Computer equipment and software</td> <td style="vertical-align:top;"> </td> <td style="vertical-align:top;">3 years</td> </tr> <tr style="height:10pt;word-break:break-word;white-space:pre-wrap;"> <td style="vertical-align:top;">Laboratory equipment and office furniture</td> <td style="vertical-align:top;"> </td> <td style="vertical-align:top;">5 years</td> </tr> <tr style="height:10pt;word-break:break-word;white-space:pre-wrap;"> <td style="vertical-align:top;">Leasehold improvements</td> <td style="vertical-align:top;"> </td> <td style="vertical-align:top;">Shorter of useful life or remaining term</td> </tr> </table></div> Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in interest and other income (expense). Expenditures for repairs and maintenance are charged to expense as incurred.</div><div style="font-size:10pt;font-family:Times New Roman;">Impairment of long-lived assetsThe Company evaluates its long-lived assets, which consist primarily of property and equipment and operating lease right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets (or asset groups) may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairment losses recognized during the years ended December 31, 2023, 2022 and 2021.</div><div style="font-size:10pt;font-family:Times New Roman;">Freestanding financial instruments and derivatives</div>Pursuant to a license agreement between the President and Fellows of Harvard College, or Harvard, and the Company, or the Harvard License Agreement, and a license agreement with The Broad Institute, Inc., or Broad Institute, and the Company, or the Broad License Agreement, (see Note 10), the Company is required to make success payments to Harvard and Broad Institute based the achievement of specified multiples of the initial weighted average value of the Company’s redeemable convertible Series A-1 Preferred Stock and the Company’s redeemable convertible Series A-2 Preferred Stock, or together the Series A Preferred, at specified valuation dates, payable in cash or Company common stock. Subsequent to the IPO, the amount of the success payments is based on the market value of Beam’s common stock. The success payments are accounted for as derivatives under ASC 815, Derivatives and Hedging and were initially recorded at fair value with a corresponding charge to research and development expense. The liabilities are recorded at fair value at each balance sheet date with all changes in value recognized in other income (expense), in the consolidated statement of operations and other comprehensive loss. The Company will continue to adjust the liability for changes in fair value until the earlier of the achievement or expiration of the success payment obligation. To determine the estimated fair value of the success payments, the Company used a Monte Carlo simulation model, which models the value of the liability based on several key variables, including probability of event occurrence, timing of event occurrence, as well as the value of the Series A Preferred, prior to the IPO, and the value of the Company’s common stock, subsequent to the IPO. <div style="font-size:12pt;font-family:Times New Roman;">Leases and rent expenseThe Company accounts for leases using a right-of-use, or ROU, model, which recognizes that, at the date of commencement, a lessee has a financial obligation to make lease payments to the lessor for the right to use the underlying asset during the lease term.At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present in the arrangement. Leases with a term greater than one year are recognized on the balance sheet as ROU assets and short-term and long-term lease liabilities, as applicable. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. The Company typically only includes an initial lease term in its assessment of the term of the lease arrangement. It also considers termination options and factors those into the determination of lease payments. Options to renew a lease are not included in the lease term unless there is reasonable certainty that the Company will renew.Operating lease liabilities and their corresponding ROU assets are recorded based on the present value of lease payments over the expected remaining lease term. Certain adjustments to the ROU asset may be required for items such as incentives received. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate, which reflects the fixed rate at which it could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term.The Company is required to pay fees for operating expenses in addition to monthly base rent for certain operating leases (non-lease components). The Company has elected the practical expedient which allows non-lease components to be combined with lease components for all asset classes. Variable lease payments are not included within the lease right-of-use asset and lease liability on the consolidated balance sheet, and instead are reflected as expense in the period they are incurred.Leasehold improvements are not unique and are retained by the lessor at the end of the lease. However, in the case of a space designed to be suitable for the Company’s specific real estate needs and if the Company is responsible for cost overruns, the Company is the accounting owner of the leasehold improvements and costs associated are capitalized. The Company’s real estate operating leases provide for scheduled annual rent increases throughout the lease terms. The Company recognizes the effects of the scheduled rent increases on a straight-line basis over the full terms of the lease. Tenant improvement allowances, if any, provided by a landlord are recorded as a reduction of the ROU asset related to that lease at lease commencement.</div><div style="font-size:10pt;font-family:Times New Roman;">Asset acquisitionsThe Company measures and recognizes asset acquisitions that are not deemed to be business combinations based on the cost to acquire the assets, which includes transaction costs, and the consideration is allocated to the items acquired based on a relative fair value methodology. Goodwill is not recognized in asset acquisitions. In an asset acquisition, the cost allocated to acquire in-process research and development with no alternative future use is charged to research and development expense at the acquisition date.At the time of acquisition, the Company determines if a transaction should be accounted for as a business combination or acquisition of assets.</div><div style="font-size:10pt;font-family:Times New Roman;">Contingent consideration liabilitiesThe Company may be required to make milestone payments to the former stockholders and optionholders of Guide Therapeutics, Inc., or Guide, in the form of its common stock based on the achievement of certain product and technology milestones. The payments are accounted for under ASC 480, Distinguishing Liabilities from Equity. These contingent consideration liabilities are carried at fair value which was estimated by applying a probability-based model, which utilized inputs primarily based upon the achievement and related timing of certain product and technology milestones that were unobservable in the market. The estimated fair value of contingent consideration liabilities, initially measured and recorded on the acquisition date, are considered to be a Level 3 measurement and are reviewed quarterly, or whenever events or circumstances occur that indicate a change in fair value. The contingent consideration liabilities are recorded at fair value at the end of each reporting period with changes in estimated fair values recorded in other income (expense) in the consolidated statements of operations and other comprehensive loss.The estimated fair value is determined based on probability adjusted discounted cash flow model that include significant estimates and assumptions pertaining to technology and product development. Significant changes in any of the probabilities of success or in the probabilities as to the periods in which milestones would be achieved would result in a significantly higher or lower fair value measurement. The Company will continue to adjust the liabilities for changes in fair value until the earlier of the achievement or expiration of the obligations.</div><div style="font-size:12pt;font-family:Times New Roman;">Revenue recognitionAt inception, the Company determines whether contracts are within the scope of ASC 606 or other topics. For contracts that are determined to be within the scope of ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods and services. To achieve this core principle, the Company applies the following five steps: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when the performance obligation is satisfied. The Company only applies the five-step model to contracts when it determines that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration.Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. To the extent a contract includes multiple promised goods and services, the Company applies judgment to determine whether promised goods and services are both capable of being distinct and are distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation.The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods and services to the customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method, depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in management’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes. Determining the transaction price requires significant judgment and is discussed in further detail for each of the Company’s license and collaboration agreements in Note 11.If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. Determining the standalone selling price requires significant judgment and is discussed in further detail for each of the Company’s license and collaboration agreements in Note 11.The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized over time if either (i) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, (ii) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or (iii) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer.Licenses of intellectual property, or IP: If the license to the Company’s IP is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from consideration allocated to the license when the license is transferred to the customer and the customer can use and benefit from the licenses. For licenses that are combined with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. The Company generally recognizes revenue using the cost incurred to date as compared to the total estimated cost. The impact on revenue of changes in total estimated costs are recognized on a cumulative basis in the period that the change occurs. If estimates of the total cost change, or if contract amendments change the scope of the performance obligation, the required adjustments to revenue could be material. Determining the revenue recognition of IP licenses requires significant judgment and is discussed in further detail for each of the Company’s license and collaboration agreements in Notes 10 and 11.Milestone payments: At the inception of each arrangement that includes development or regulatory milestone payments, the Company evaluates the probability of reaching the milestones and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur in the future, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s, such as regulatory approvals, are not considered probable of being achieved until those approvals are received and therefore consideration included in the transaction price is constrained. The transaction price is then allocated to each performance obligation on a relative standalone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and earnings in the period of adjustment.Commercial Milestone Payments and Royalties: For arrangements that include sales-based royalties, including milestone payments based on levels of sales, if the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue resulting from any of its agreements.When no remaining performance obligations are required of the Company, or following the completion of the performance obligation period, such amounts are recognized as revenue upon transfer of control of the goods or services to the customer. Generally, all amounts received or due other than sales-based milestones and royalties are classified as license and collaboration revenue. Sales-based milestones and royalties will be recognized as royalty revenue at the later of when the related sales occur or when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).Deferred revenue expected to be recognized within the next twelve months is classified as a current liability. </div><div style="font-size:10pt;font-family:Times New Roman;">Contract balancesThe Company recognizes a contract asset when the Company transfers goods or services to a customer before the customer pays consideration or before payment is due, excluding any amounts presented as an account or other receivable. A contract asset is an entity’s right to consideration in exchange for goods or services that the entity has transferred to a customer. The contract liabilities, or deferred revenue, primarily relate to contracts where the Company has received payment, but it has not yet satisfied or fully satisfied the related performance obligations. Upfront payments and fees are recorded as deferred revenue upon receipt or when due and may require deferral of revenue recognition to a future period until the Company satisfies its obligations under these arrangements. Upfront payment contract liabilities resulting from the Company’s license agreements do not represent a financing component as the payment is not financing the transfer of goods or services, and the technology underlying the licenses granted reflects research and development expenses already incurred by the Company.<div style="font-size:10pt;font-family:Times New Roman;">The changes in the total

Research and development costs consist of costs incurred in performing research and development activities, including salaries and bonuses, stock-based compensation, employee benefits, facilities costs, laboratory supplies, depreciation, manufacturing expenses, preclinical expenses, consulting, and other contracted services. The cost of obtaining licenses for certain technology or IP is recorded to research and development expense when incurred if the licensed technology or IP has not yet reached technological feasibility and has no alternative future use. Costs for certain research and development activities are recognized based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development costs.</div><div style="font-size:10pt;font-family:Times New Roman;">Stock-based compensationThe Company’s stock-based compensation program allows for grants of stock options, restricted stock awards and restricted stock units. Grants are awarded to employees and non-employees, including directors.The Company accounts for stock-based compensation in accordance with ASC Topic 718, Compensation-Stock Compensation, or ASC 718. ASC 718 requires all stock-based payments to employees, non-employees and directors to be recognized as expense in the consolidated statements of operations and other comprehensive loss based on their fair values. The Company estimates the fair value of options granted using the Black-Scholes option pricing model, or Black-Scholes, for stock option grants to both employees and non-employees. The fair value of the Company’s common stock is used to determine the fair value of restricted stock awards and restricted stock units.Stock-based compensation awards are subject to either service- or performance-based vesting conditions. Compensation expense related to awards to employees, directors and non-employees with service-based vesting conditions is recognized on a straight-line basis based on the grant date fair value over the associated service period of the award, which is generally the vesting term. Compensation expense related to awards to employees with performance-based vesting conditions is recognized based on grant date fair value over the requisite service period using the accelerated attribution method to the extent achievement of the of performance condition is probable.The Black-Scholes option pricing model requires inputs based on certain subjective assumptions, including (i) the expected stock price volatility, (ii) the expected term of the award, (iii) the risk-free interest rate, and (iv) expected dividends. The Company bases its computation of expected volatility on the historical volatility of a representative group of public companies with similar characteristics to the Company, including stage of product development and life science industry focus, weighted with its own volatility for the period in which its stock has been publicly traded. The historical volatility is calculated based on a period of time commensurate with expected term assumption. The Company uses the simplified method as prescribed by the SEC Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term for options granted to employees and non-employees, whereby the expected term equals the arithmetic average of the vesting term and the original contractual term of the options due to its lack of sufficient historical data. The risk-free interest rate is based on U.S. Treasury securities with a maturity date commensurate with the expected term of the associated award. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock. The Company recognizes forfeitures as they occur.</div><div style="font-size:10pt;font-family:Times New Roman;">Patent costsAll patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred. Due to the uncertainty about the recovery of the expenditure, amounts incurred are classified as general and administrative expenses in the accompanying consolidated statements of operations and other comprehensive loss.</div><div style="font-size:10pt;font-family:Times New Roman;">Variable interest entitiesThe Company reviews each legal entity in which it has a financial interest to determine whether or not the entity is a variable interest entity, or VIE. If the entity is a VIE, the Company assesses whether or not it is the primary beneficiary of that VIE based on a number of factors, including (i) which party has the power to direct the activities that most significantly affect the VIE’s economic performance, (ii) the parties’ contractual rights and responsibilities pursuant to any contractual agreements and (iii) which party has the obligation to absorb losses or the right to receive benefits from the VIE. If the Company determines that it is the primary beneficiary of a VIE, it consolidates the financial statements of the VIE into its consolidated financial statements. If the Company determines that it is no longer the primary beneficiary of a consolidated VIE, or no longer has a variable interest in the VIE, the Company deconsolidates the VIE in the period that the determination is made.</div><div style="font-size:10pt;font-family:Times New Roman;">Income taxesThe Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s financial statements and tax returns. Deferred tax assets and liabilities are determined based upon the differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities and for loss and credit carryforwards, using enacted tax rates expected to be in effect in the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that these assets may not be realized. The Company determines whether it is more likely than not that a tax position will be sustained upon examination. If it is not more likely than not that a position will be sustained, none of the benefit attributable to the position is recognized. The tax benefit to be recognized for any tax position that meets the more-likely-than-not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon resolution of the contingency. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for income taxes.</div><div style="font-size:10pt;font-family:Times New Roman;">Comprehensive lossComprehensive loss is defined as the change in stockholders’ equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive loss includes net loss as well as other changes in equity that are excluded from net loss. The Company’s only element of other comprehensive loss is unrealized gains and losses on marketable securities.</div><div style="font-size:10pt;font-family:Times New Roman;">Net loss per shareThe Company follows the two-class method when computing net loss per share, as the Company has issued shares that meet the definition of participating securities. The two-class method determines net loss per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net loss attributable to common stockholders is computed by adjusting net loss attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, including potential dilutive common shares assuming the dilutive effect of common stock equivalents.For purposes of the dilutive net loss per share calculation, stock options and stock units for which the performance and market vesting conditions have been deemed probable, potential dilutive securities, unvested restricted stock, and common stock options are considered to be common stock equivalents, while stock options and stock units with performance- or market-based vesting conditions that were not deemed probable of meeting the applicable vesting conditions are not considered to be common stock equivalents.Accordingly, in periods in which the Company reported a net loss, such losses were not allocated to such participating securities. In periods in which the Company reported a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders was the same as basic net loss per share attributable to common stockholders, since dilutive common shares were not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the years ended December 31, 2023, 2022 and 2021.</div><div style="font-size:12pt;font-family:Times New Roman;">Equity method of accountingIn circumstances where the Company has the ability to exercise significant influence, but not control, over the operating and financial policies of an entity in which the Company has an investment in common stock or in-substance common stock, the Company utilizes the equity method of accounting for recording related investment activity. In assessing whether the Company exercises significant influence, the Company considers the nature and magnitude of the investment, participating rights the Company holds, and relevant factors such as the presence of a collaborative or other business relationship. Under the equity method of accounting, the Company’s investments are initially recorded at cost on the consolidated balance sheets. Upon recording an equity method investment, the Company evaluates whether there are basis differences between the carrying value and fair value of the Company’s proportionate share of the investee’s underlying net assets. Typically, the Company amortizes basis differences identified on a straight-line basis over the underlying asset’s or liability's estimated useful lives when calculating the attributable earnings or losses, excluding the basis differences attributable to in-process research and development, or IPR&D, that has no alternative future use. To the extent a basis difference relates to IPR&D and the investee is not a business as defined in ASC 805, Business Combinations, or ASC 805, the Company immediately expenses such basis difference related to IPR&D. If the Company is unable to attribute all of the basis difference to specific assets or liabilities of the investee, the residual excess of the cost of the investment over the proportional fair value of the investee’s assets and liabilities is considered to be Equity Method Goodwill and is recognized within the equity investment balance, which is tracked separately within the Company’s memo accounts. The Company subsequently records in the consolidated statements of operations and comprehensive loss its share of income or loss of the other entity within the loss from equity method investment line item. If the share of losses exceeds the carrying value of the Company’s investment, the Company will suspend recognizing additional losses and will continue to do so unless it commits to providing additional funding or commits to guarantee investee liabilities. The Company evaluates its equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired and considers qualitative and quantitative factors including the investee’s financial metrics, product and commercial outlook and cash usage. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period and the investment is written down to fair value.At December 31, 2023, the Company accounted for its investment in Orbital under the equity method of accounting. The Company has no carrying value related to this investment as of December 31, 2023 and 2022. Refer to Note 11 for further details.</div><div style="font-size:10pt;font-family:Times New Roman;">Segment and geographic informationOperating segments are defined as components of an entity about which separate discrete information is available for evaluation by the chief operating decision maker, or CODM, or decision-making group, in deciding how to allocate resources and in assessing performance.

Concentrations of credit risk Financial instruments that are potentially subject to significant concentration of credit risk consist primarily of cash, cash equivalents, marketable securities, and restricted cash. The Company attempts to minimize the risk related to marketable securities by working with highly rated financial institutions that invest in a broad and diverse range of financial instruments. The Company has established guidelines relative to credit ratings and maturities intended to safeguard principal balances and maintain liquidity.

eligible to receive up to an additional $100.0 million in technology milestone payments and $220.0 million in product milestone payments, payable in the Company’s common stock valued using the volume-weighted average price of the Company’s stock over the ten-day trading period ending two trading days prior to the date on which the applicable milestone is achieved. As these milestones are payable with a variable number of shares of the Company’s common stock, the milestone payments result in liability classification under ASC 480, Distinguishing Liabilities from Equity. These contingent consideration liabilities are carried at fair value which was estimated by applying a probability-based model, which utilized inputs based on timing of achievement that were unobservable in the market. These contingent consideration liabilities are classified within Level 3 of the fair value hierarchy.<div style="font-size:10pt;font-family:Times New Roman;">The following variables were incorporated

9. Guide acquisitionOn February 23, 2021, the Company entered into the Guide Merger Agreement. Under the Guide Merger Agreement, the Company paid Guide’s former stockholders and optionholders upfront consideration in an aggregate amount of $120.0 million, excluding customary purchase price adjustments and closing costs, in shares of the Company’s common stock, based upon the volume-weighted average price of the Company’s stock over the ten trading-day period ending on February 19, 2021. Pursuant to the Guide Merger Agreement, the Company acquired all of the issued and outstanding shares of Guide. The Company issued a total of 1,087,153 shares of its common stock valued at $120.0 million in connection with the upfront payment to Guide’s former stockholders and optionholders. The Guide transaction resulted in the acquisition of certain know-how and intellectual property assets related to Guide’s proprietary in vivo LNP screening technology and its library of lipids and lipid nanoparticle formulations identified using the screening technology. Management determined that the acquired assets do not meet the definition of a business pursuant to ASC 805, as substantially all of the fair value of the acquired assets is concentrated into one identifiable asset, the LNP screening technology and associated lipid library. As of the date of closing of the transactions contemplated by the Guide Merger Agreement, or the Guide Merger Agreement Date, the asset acquired had no alternative future use and had not reached a stage of technological feasibility. As a result, all share-based and cash payment obligations have been recorded as research and development expense in the consolidated statements of operations and other comprehensive loss in the amount of $155.0 million. The total transaction price was allocated to the assets acquired and liabilities assumed on a relative fair value basis.In addition, Guide’s former stockholders and optionholders are eligible to receive up to an additional $100.0 million in technology milestone payments and $220.0 million in product milestone payments, payable in the Company’s common stock valued using the volume-weighted average price of the Company’s common stock over the ten trading-day period ending two trading days prior to the date on which the applicable milestone is achieved.The Company determined that all future technology and product milestone payments are classified as liabilities under ASC 480 and therefore the Company recorded a liability for these milestone payments as of the Guide Merger Agreement Date at fair value of $36.5 million. These contingent consideration liabilities are remeasured at fair value each financial reporting period, with the resulting impact reflected in the Company’s consolidated statements of operations and other comprehensive loss, presented within other income (expense).<div style="font-size:10pt;font-family:Times New Roman;">The transaction price was determined and allocated as follows (in thousands):

10. License agreementsThe Company has various license agreements related to technology used in its research and development activities. The license agreements may include up-front payments, option fees, ongoing maintenance fees, sublicense fees, royalty-based payments, milestone payments, success-based payments, and other payments. Option fees, when applicable, are recognized when exercised, maintenance fees, sublicense fees, and other payments are recorded as incurred based on the estimated amounts due or that will ultimately be paid. Contingent payments that are not required to be accounted for as a derivative are recognized as incurred. As the success-based payments due under the Company’s license arrangements are derivatives, the change in the fair value of the success-based payments are recognized in a separate line item in the statement of operations and comprehensive loss, as discussed further below. The total contingent obligations and non-royalty sublicense fees included in research and development expenses in the statement of operations and comprehensive loss were $43.5 million, $2.7 million, and $39.9 million for the years ended December 31, 2023, 2022, and 2021, respectively. The value attributable to sublicenses and the related sublicense fees due under the Company’s license agreements may require estimates and other judgments related to contractual requirements, which creates uncertainty over the ultimate amount that would be paid under these arrangements. Contractual amounts due are accrued and if a contingency exists related to the interpretation of the amounts due under the license agreement, the Company recognizes a liability for the amount that is probable and estimable. When no amount within the range of potential payments is a better estimate than any other amount, however, the minimum amount in the range is accrued. If some amount within a range of loss appears to be a better estimate than any other amount within the range, that amount is accrued. The Company’s accrued liabilities for license fees includes estimates, including approximately $43.3 million of contingent obligations that may be due associated with payments received under the Lilly Agreement for which discussions are continuing related to the potential applicability to such payments of the terms of license agreements. As of December 31, 2023, management believes that it is remote that an adjustment to its estimated accrual would result in a material charge in excess of the amount accrued. The ultimate amount paid may differ materially from the estimated amounts. Harvard license agreement In June 2017, the Company entered into the Harvard License Agreement for certain base editing technology pursuant to which the Company received an exclusive, worldwide, sublicensable, royalty-bearing license under specified patent rights to develop and commercialize licensed products and a nonexclusive, worldwide, sublicensable, royalty-bearing license under certain patent rights to research and develop licensed products. The Company agreed to use commercially reasonable efforts to develop licensed products in accordance with the development plan, to introduce any licensed products that gain regulatory approval into the commercial market, to market licensed products that have gained regulatory approval following such introduction into the market, and to make licensed products that have gained regulatory approval reasonably available to the public. The license term extends until the later of the expiration of (i) the last to expire licensed patent covering a licensed product, (ii) the period of exclusivity associated with a licensed product or (iii) a certain period after the first commercial sale of a licensed product, unless terminated earlier by either party under certain provisions.Partial consideration for the rights granted under the Harvard License Agreement include success payments, which are further described below. Success Payments – Under the Harvard License Agreement, Harvard is entitled to receive success payments, in cash or shares of Company stock, determined based upon the achievement of specified multiples of the initial weighted average value of the Company’s Series A Preferred at specified valuation dates. The success payments range from $5.0 million to a maximum of $105.0 million and have valuation multiples that range from 5 times to 40 times the initial weighted average value of the Series A Preferred. Subsequent to the Company’s February 2020 IPO, the amount of success payments is based on the market value of the Company's common stock.The Company is required to make success payments to Harvard during a period of time, or the Harvard Success Payment Period, which has been determined to be the later of (1) the ninth anniversary of the Harvard License Agreement or (2) the earlier of (a) the twelfth anniversary of the Harvard License Agreement and (b) the third anniversary of the first date on which a licensed product receives regulatory approval in the United States. During the Harvard Success Payment Period, the Company will perform a calculation of any amounts owed to Harvard on each rolling 90-day period, commencing one year after the Company’s IPO. In May 2021, the first success payment measurement occurred and amounts due to Harvard were calculated to be $15.0 million. The Company elected to make the payment in shares of the Company’s common stock and issued 174,825 shares of the Company’s common stock to settle this liability on June 10, 2021. The Company may owe Harvard success payments of up to an additional $90.0 million.<div style="font-size:10pt;font-family:Times New Roman;">The following table summarizes the Company’s success payment

Harvard an annual license maintenance fee ranging from low-to-mid five figures to low six figures, depending on the calendar year. The Company is responsible for the payment of certain patent prosecution and maintenance costs incurred by Harvard related to licensed patents. To the extent achieved, the Company is obligated to pay up to an aggregate of $75.9 million in product development and regulatory approval milestones, or Harvard Product Milestones. If the Company completes a change of control during the term of the Harvard License Agreement, then certain of the milestone payments would be increased. To the extent there are sales of a licensed product, the Company is required to pay low single digit royalties on net sales. The Company is entitled to certain reductions and offsets on these royalties with respect to a licensed product in a given country. If the Company sublicenses its rights to develop or commercialize a licensed product under the Harvard License Agreement to a third party and the Company receives non-royalty sublicense income, then Harvard is entitled to a percentage of such consideration, ranging from the high single digits to low double digits depending on the date in which such sublicense agreement is executed and the stage of development of the Company’s licensed products at such time. The annual maintenance fees are recorded as an expense on an annual basis based on the stated amount for the applicable year. Annual patent costs are expensed as incurred. Upon determination that a Harvard Product Milestone is probable to occur, the amount due will be recorded as research and development expense. The Company will monitor the Harvard Product Milestone payments for this arrangement on an ongoing basis. To the extent products are commercialized under the Harvard License Agreement, the Company will accrue royalty expense and sublicense nonroyalty payments, as applicable, for the amount it is obligated to pay, with adjustments as sales are made. Broad license agreement In May 2018, the Broad License Agreement was entered into with Broad Institute for certain RNA base editing technology including an RNA editor platform.

Editas license agreement In May 2018, the Company entered into a license agreement, or the Editas License Agreement, with Editas Medicine, Inc., or Editas. Pursuant to the Editas License Agreement, Editas granted to the Company licenses and options to acquire licenses to certain intellectual property rights owned or controlled by Editas, for specified uses. More specifically, Editas granted to the Company a worldwide, exclusive, sublicensable, license (subject to certain exceptions and conditions) under certain intellectual property controlled by Editas for the use of base editing therapies for the treatment of any field of human diseases and conditions, subject to certain exceptions, or the Beam Field, and the licenses granted or to be granted under the Editas License Agreement, or the Editas Development and Commercialization License.

Unless earlier terminated by either party pursuant to the terms of the agreement, the Editas License Agreement will continue in full force and effect and will expire on a licensed product-by licensed product and country-by-country basis upon the later of (i) the last-to-expire royalty term under any applicable institutional license to Editas and (ii) the date at which such product is no longer covered by a valid claim of a licensed Editas-owned patent in such country. The Company has the right, at its sole discretion, at any time to terminate the Editas License Agreement in its entirety or on a group-by-group of intellectual property basis, upon ninety days written notice to Editas. Upon termination of the Editas License Agreement, all rights and licenses granted by Editas to the Company (including the rights to exercise options and obtain such licenses) will immediately terminate and patents within a group of patents will no longer be deemed licensed patents. Expiration or termination of the Editas License Agreement for any reason does not release either party of any obligation or liability which had accrued, or which is attributable to a period prior to such expiration or termination.The option exercise fees under the agreement will be recorded as research and development expense, if and when the Company exercises such options. To date, no options have been exercised. The annual maintenance fees are recorded as an expense on an annual basis based on the stated amount for the applicable year. Annual patent costs are expensed as incurred. In addition, the Company is required to make certain development, regulatory and commercial milestone payments to Editas upon the achievement of specified milestones. To the extent applicable, sublicense income payments will be accrued for the amount the Company is obligated to pay under each applicable in-license as amounts are due to Editas. Lastly, to the extent products are commercialized under the Editas License agreement, the Company will accrue royalty expense for the amount it is obligated to pay, with adjustments as sales are made. 43500000 2700000 39900000

In May 2018, the Company entered into a license agreement, or the Editas License Agreement, with Editas Medicine, Inc., or Editas. Pursuant to the Editas License Agreement, Editas granted to the Company licenses and options to acquire licenses to certain intellectual property rights owned or controlled by Editas, for specified uses. More specifically, Editas granted to the Company a worldwide, exclusive, sublicensable, license (subject to certain exceptions and conditions) under certain intellectual property controlled by Editas for the use of base editing therapies for the treatment of any field of human diseases and conditions, subject to certain exceptions, or the Beam Field, and the licenses granted or to be granted under the Editas License Agreement, or the Editas Development and Commercialization License. Additionally, Editas granted to the Company a royalty-free, non-exclusive license under certain intellectual property owned or controlled by Editas to perform research activities in the Beam Field, or the Editas Research License. Editas provided the Company with an exclusive option to obtain an Editas Development and Commercialization License to three additional groups of intellectual property owned or controlled by Editas, on a group by group basis, during the specified option period, subject to certain exceptions. Pursuant to the Editas License Agreement, the Company will use commercially reasonable efforts to develop a product that includes the rights licensed to the Company within a specified period of time and to commercialize any such products that have received regulatory approval in certain specified countries.Additional consideration will be due to Editas if the Company elects to exercise its option to obtain an Editas Development and Commercialization License to any of the three categories of intellectual property underlying the Editas Research License, for a fee ranging from a mid-teen million dollar amount to a low to mid-eight digit dollar amount per group, depending on the timing of the option exercise. Additionally, the Company is required to reimburse Editas for certain payments Editas may be obligated to make under existing Editas license agreements related to the intellectual property being licensed to the Company, including (i) development, regulatory and commercial milestone payments and certain sublicense income payments due as a result of the Editas License Agreement and (ii) a percentage of the annual maintenance fees and patent fees due to certain of the Editas’ licensors. In addition, to the extent any products are commercialized under an Editas Development and Commercialization License, the Company would be required to make royalty payments equivalent to the royalties that would be due from Editas to any applicable licensors of Editas related to the sales of such licensed products, plus an additional tiered low- to mid-single digit royalty, depending on whether such licensed product is covered by an Editas-owned patent.

11. Collaboration and license agreementsEli Lilly and CompanyIn October 2023, the Company entered into a Transfer and Delegation Agreement, or the Lilly Agreement, with Eli Lilly and Company, or Lilly, pursuant to which Lilly acquired certain assets and other rights under the Company’s amended collaboration and license agreement, or the Verve Agreement, with Verve Therapeutics, Inc., or Verve, including the Company’s opt-in rights to co-develop and co-commercialize Verve’s base editing programs for cardiovascular disease (see discussion below related to the Verve Agreement). The Company granted Lilly an exclusive sublicense to the Verve technology originally licensed to the Company under the Verve Agreement. Lilly also acquired the right to receive any future milestone or royalty payments payable by Verve under the Verve Agreement and the rights and obligations to designate representatives and participate on the joint steering committee with Verve. The Company received a $200.0 million nonrefundable upfront payment and is eligible to receive up to $350.0 million in potential future development-stage payments upon the completion of certain clinical, regulatory and alliance events. If Lilly does not opt-in to co-develop and co-commercialize a licensed product, Lilly is obligated to pay the Company a percentage of any royalties received from Verve for sales of such product, subject to certain caps on a licensed product-by-licensed product basis.For a period of six years from the effective date of the Lilly Agreement, Lilly has the right to request the Company to perform any critical research and development services, if Lilly reasonably determines that the Company is uniquely able to provide such services and other conditions are met, including that no other third parties can provide such services. The parties will negotiate an agreement governing the Company’s performance of such activity, if any, and the Company will be compensated for any services at approximately cost plus a margin. The Company has not been requested to perform any services and believes it is remote that Beam would be requested to provide any services. In connection with the Lilly Agreement, the Company and Lilly entered into a Stock Purchase Agreement providing for the sale and issuance of 2,004,811 shares of the Company’s common stock to Lilly for an aggregate purchase price of $50.0 million. The Company received the consideration under the Stock Purchase Agreement of $50.0 million in October and the upfront payment of $200.0 million in November 2023. The Lilly Agreement and Stock Purchase Agreement were negotiated at the same time as a package and have been accounted for as one combined contract. The Company accounts for the component of the arrangement to transfer common stock to Lilly under ASC 505, Equity, and the revenue component under ASC 606, as it includes a customer-vendor relationship as defined under ASC 606 and meets the criteria to be considered a contract. The Company first applied the guidance in ASC 505 to measure the fair value of the common stock issued and allocated the remaining consideration to the ASC 606 component of the arrangement.The overall ASC 606 transaction price as of the inception of the contract was determined to be $216.4 million, which is comprised of the upfront payment of $200.0 million and the residual value of the proceeds received in excess of the fair value of the common stock sold to Lilly of $16.4 million. The fair value of the common stock issued to Lilly was $33.6 million, as determined by management with the assistance of a third-party valuation specialist. There is no variable consideration included in the transaction price at inception. The Company will re-evaluate the transaction price at each reporting period.The Company concluded that the collaboration rights and licenses to intellectual property have the same pattern and timing of transfer and are transferred as of the effective date of the Lilly Agreement. Lilly’s right to request research and development services represents an optional purchase in the agreement that does not constitute a material right. All other items promised to Lilly are immaterial in the context of the agreement. The Company recognized revenue for the performance obligation at a point-in-time in October 2023 as all requirements related to the performance obligation have been completed. Any consideration received related to Lilly’s optional purchase of the Company’s research and development services will be accounted for as a separate contract if and when the option is exercised in accordance with ASC 606. During the year ended 2023 the Company recognized $216.4 million of revenue related to the Lilly Agreement. As of December 31, 2023, there was no deferred revenue related to the Lilly Agreement. OrbitalIn September 2022, the Company entered into a License and Research Collaboration Agreement, or the Orbital Agreement, with Orbital Therapeutics, Inc., or Orbital. Under the terms of the Orbital Agreement, the Company will collaborate with Orbital to advance nonviral delivery and ribonucleic acid, or RNA, technology by providing Orbital with certain proprietary materials, a non-exclusive research license to certain RNA technology and nonviral delivery technology controlled by the Company, and by performing research and development support services as outlined in a research plan. The Company also granted Orbital an exploitation license to certain RNA technology and nonviral delivery technology controlled by the Company. The exploitation license is exclusive in the fields of vaccines and certain protein therapeutics and nonexclusive in all other fields other than gene editing and conditioning. The collaboration is managed on an overall basis by a Joint Steering Committee, or JSC, comprised of an equal number of representatives from the Company and Orbital.In exchange for the licenses and services provided by the Company under the Orbital Agreement, the Company received a non-exclusive research license to certain RNA technology and nonviral delivery technology controlled by Orbital, and research and development support services as outlined in a research plan. Orbital also granted the Company an exploitation license to certain RNA technology and nonviral delivery technology controlled by Orbital. The exploitation license is exclusive in the fields of gene editing and conditioning and nonexclusive in all other fields other than vaccines and certain protein therapeutics. The Company also received 75 million shares of Orbital’s common stock at closing.The research plan has a term of three years and can be extended for unspecified periods upon mutual agreement between the Company and Orbital. The exploitation licenses are exclusive for an initial research term of three years, which may be extended for up to two successive one-year periods by mutual agreement between the Company and Orbital. Either party may terminate the licenses granted to it under the Orbital Agreement for convenience on a product-by-product basis at any time by providing 90 days’ prior written notice.The Company accounts for the consideration received under the Orbital Agreement under ASC 606, Revenue from Contracts with Customers, or ASC 606, as it includes a customer-vendor relationship as defined under ASC 606 and meets the criteria to be considered a contract. The overall transaction price as of the inception of the contract was determined to be $25.5 million, which represents the fair value of the Company’s equity interest in Orbital’s common stock at inception. There is no variable consideration included in the transaction price.The Company concluded that the research and exploitation licenses are not distinct from the other promises in the Orbital Agreement, and as such the Company determined that the licenses combined with the research and development services, know-how transfers, committee participation and materials transfer represent a performance obligation. The Company recognizes revenue associated with the Orbital performance obligation over time as it is satisfied during the term of the agreement, which is three years. The Company recognized $8.5 million and $2.1 million of revenue during the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, there was $8.5 million and $6.4 million of current and long-term deferred revenue, respectively, related to the Orbital Agreement.Beam does not have a controlling financial interest in Orbital as Beam does not have the power to direct the activities of Orbital. The Company has significant influence over Orbital through its noncontrolling representation on Orbital’s board of directors and the Company’s equity interest in Orbital. Accordingly, the Company does not consolidate the financial statements of Orbital and accounts for its investment using the equity method of accounting. As of the closing date in September 2022, the fair value of the Company’s investment in Orbital was $25.5 million. The fair value of the Orbital common stock was determined by management with the assistance of a third-party valuation specialist. In determining the fair value of the Company’s investment, the valuation specialist used an option pricing model backsolve approach based on Orbital's most recent funding of preferred stock. The valuation requires the input of certain subjective assumptions. The key assumptions used in the option pricing model, which are level 3 inputs, include the anticipated holding period to an exit and liquidity event, the volatility of market participants (68%) and the discount for lack of marketability (43%). At the date of the investment, a basis difference was identified as the carrying value of the Company’s investment in Orbital exceeded the Company’s proportionate share of the underlying net assets in Orbital. The Company concluded that the basis difference was primarily attributable to Orbital’s IPR&D assets. As Orbital did not meet the definition of a business due to substantially all of the estimated fair value of the gross assets being concentrated in the group of similar IPR&D assets, the basis difference attributable to the IPR&D with no alternative future use was immediately expensed as of the date of the investment. The Company’s proportionate share of the basis difference exceeded its carrying value of the equity method investment in Orbital and the equity investment balance was reduced to zero. There is no commitment for the Company to provide financial support to Orbital. The Company did not recognize a gain or loss from the equity method investment for the year ended December 31, 2023 and recognized a loss of $25.5 million in association with the basis difference charge in the Company’s consolidated statements of operations for the year ended December 31, 2022.PfizerIn December 2021, the Company entered into a research collaboration agreement, or the Pfizer Agreement, with Pfizer Inc., or Pfizer, focused on the use of certain of the Company’s base editing technology to develop in vivo therapies for rare genetic diseases of the liver, muscle, and central nervous system. Under the terms of the Pfizer Agreement, the Company will conduct all research activities through development candidate selection for three base editing programs that target specific genes corresponding to specific diseases that are the subject of such programs. Pfizer will have exclusive rights to license each of the three programs at no additional cost, each an Opt-In Right, and will assume responsibility for subsequent development and commercialization. At the end of the Phase 1/2 clinical trials, the Company may elect to enter into a global co-development and co-commercialization agreement with Pfizer with respect to one program licensed under the collaboration for an option exercise fee equal to a percentage of the applicable development costs incurred by Pfizer, or the Participation Election. In the event the Company elects to exercise its Participation Election, upon the payment of its option exercise fee, Pfizer and the Company would share net profits as well as development and commercialization costs in a 65%/35% (Pfizer/Company) split for such program. The research collaboration is managed on an overall basis by a Joint Research Committee, or JRC, formed by an equal number of representatives from the Company and Pfizer.At the inception of the Pfizer Agreement, the Company was entitled to receive a nonrefundable upfront payment of $300.0 million in consideration for the rights granted to Pfizer under the collaboration. Should Pfizer exercise its Opt-In Right for any of the three programs, the Company would be eligible to receive development, regulatory, and commercial milestones of up to $350.0 million per program, for potential total consideration of up to $1.35 billion, plus royalty payments on global net sales for each licensed program, if any. If Pfizer does not exercise its Opt-In Right for a program, the Company’s rights in such program revert to the Company and the Company will be required to pay Pfizer earn-out payments equal to a low single digit percentage of net sales earned on such program for a ten-year period, if any. As the $300.0 million upfront fee was not received by the Company as of December 31, 2021, the Company recorded a collaboration receivable for $300.0 million with a corresponding deferred revenue liability. The Company received the $300.0 million upfront payment in January 2022. During the collaboration term, Pfizer has a one-time option to substitute a disease that is the subject of a specific program with one pre-defined substitute disease. The collaboration has an initial term of four years and may be extended for an additional year on a program-by-program basis. Pfizer may terminate the Pfizer Agreement for convenience on any or all of the programs by providing 90 days’ prior written notice.The Company accounts for the Pfizer Agreement under ASC 606, as it includes a customer-vendor relationship as defined under ASC 606 and meets the criteria to be considered a contract. The overall transaction price as of the inception of the contract was determined to be $300.0 million, which is comprised entirely of the nonrefundable upfront payment. There is no variable consideration included in the transaction price at inception as the future milestone payments are fully constrained and the Company is not required to estimate variable consideration for the royalty payments at contract inception. The Company will re-evaluate the transaction price in each reporting period.The Company has concluded that the licenses to its base editing technology, including the exclusive development and commercialization rights, are not capable of being distinct from the other performance obligations, and as such the Company has determined that the licenses combined with the other research and development services represent performance obligations and no up-front revenue was recognized for the licenses. The selling price of each performance obligation was determined based on the Company’s estimated standalone selling price, or the ESSP. The Company developed the ESSP for all of the performance obligations included in the Pfizer Agreement by determining the total estimated costs to fulfill each performance obligation identified with the objective of determining the price at which it would sell such an item if it were to be sold regularly on a standalone basis. The Company allocated the stand-alone selling price to the performance obligations based on the relative standalone selling price method.The Company recognizes revenue for each performance obligation as it is satisfied during the term of the agreement using an input method. The Company allocated the transaction price of $300.0 million to each of the three performance obligations, which includes each of the three base editing programs combined with the research and development services, licenses, and exclusive development and commercialization rights. Revenue is recognized using an input method based on the actual costs incurred as a percentage of total estimated costs towards satisfying the performance obligation as this method provides the most faithful depiction of the entity’s performance in transferring control of the goods and services promised to Pfizer and represents the Company’s best estimate of the period of the obligation. The impact on revenue of changes in total estimated costs are recognized on a cumulative basis in the period that the change occurs. If estimates of the total cost change, or if contract amendments change the scope of the performance obligation, the required adjustments to revenue could be material. During the year ended December 31, 2023, the Company recognized $134.3 million, which includes a cumulative catch-up adjustment to increase revenue due to changes in estimated total costs. In 2022 the Company recognized $48.2 million of revenue related to the Pfizer Agreement. There was no revenue recognized related to the Pfizer Agreement during the year ended December 31, 2021. As of December 31, 2023, there was $42.9 million and $74.6 million of current and long-term deferred revenue, respectively, related to the Pfizer Agreement. Sana BiotechnologyIn October 2021, the Company entered into an option and license agreement, or the Sana Agreement, with Sana Biotechnology, Inc., or Sana, under which the Company granted Sana a license for non-exclusive rights to its CRISPR Cas12b nuclease system for the development and commercialization of certain engineered cellular therapy programs. In addition to the license, the Company performed an initial technology transfer following the effective date of the Sana Agreement providing Sana with certain know-how, as required under the Sana Agreement. This technology transfer occurred in 2021. Following the license transfer and completion of the initial technology transfer, Sana is responsible, at its sole expense, for the development and commercialization of therapeutic products which must contain either specified CAR antigen targets or pluripotent stem cell, or PSC, product types.As consideration for the license, the Company received an upfront payment of $50.0 million from Sana in October 2021. In addition, the Company may be eligible to receive development, regulatory, and commercial milestones of up to $65.0 million from Sana on any product candidate or product. The Company will also be entitled to receive royalties equal to a low single digit percentage of net sales on any product.For up to thirty months following the effective date of the Sana Agreement, Sana has the option to select up to a cumulative total of two additional CAR antigen targets or PSC product types for an additional fee of $10.0 million per additional CAR antigen target and additional PSC product type, or the Option Rights, for an aggregate potential additional consideration of $20.0 million. Further, for up to thirty months following the effective date of the Sana Agreement, Sana has a one-time right to substitute, in the aggregate, either one CAR antigen target or one PSC product type at no additional cost, or the Replacement Right. Sana may also select a specified number of additional or replacement genetic targets for each PSC product type at any time prior to the third anniversary of the effective date at no additional cost, or the Genetic Target Nomination Rights. Sana may terminate the Sana Agreement for convenience prior to the first commercial sale of any licensed product by providing 90 days’ prior written notice or upon 180 days’ prior written notice after first commercial sale.The Company accounts for the Sana Agreement under ASC 606 as it includes a customer-vendor relationship as defined under ASC 606 and meets the criteria to be considered a contract. The overall transaction price as of the inception of the contract was determined to be $50.0 million, which is composed entirely of the nonrefundable upfront payment. There is no variable consideration included in the transaction price at inception as the future milestone payments are fully constrained and the Company is not required to estimate variable consideration for the royalty payments at contract inception. The Company will re-evaluate the transaction price in each reporting period. The Company has identified a single performance obligation, which includes (i) the non-exclusive license granted to Sana under the Company’s patent rights and know-how and (ii) the initial technology transfer following the effective date, which occurred in 2021. The Company further concluded that the Option Rights, Replacement Right, and Genetic Target Nomination Rights did not grant Sana a material right. As the Company only identified one performance obligation, no allocation of the transaction price is required. During the year ended December 31, 2021, the Company recognized $50.0 million of revenue associated with the single performance obligation at a point in time upon the transfer of the license to Sana and completion of the initial technology transfer. The Company did not recognize revenue under the Sana Agreement for the year ended December 31, 2022. The Company recognized $1.8 million of revenue under the Sana Agreement during the year ended December 31, 2023. Apellis PharmaceuticalsIn June 2021, the Company entered into a research collaboration agreement, or the Apellis Agreement, with Apellis Pharmaceuticals, Inc., or Apellis, focused on the use of certain of the Company’s base editing technology to discover new treatments for complement system-driven diseases. Under the terms of the Apellis Agreement, the Company will conduct preclinical research on up to six base editing programs that target specific genes within the complement system in various organs, including the eye, liver, and brain. Apellis has an exclusive option to license any or all of the six programs, or in each case, an Opt-In Right, and will assume responsibility for subsequent development. The Company may elect to enter into a 50-50 U.S. co-development and co-commercialization agreement with Apellis with respect to one program instead of a license. The collaboration is managed on an overall basis by an alliance steering committee formed by an equal number of representatives from the Company and Apellis.As part of the collaboration, the Company is eligible to receive a total of $75.0 million in upfront and near-term milestones from Apellis, which is comprised of $50.0 million received upon signing and an additional $25.0 million payment on June 30, 2022, the one-year anniversary of the effective date of the Apellis Agreement, or the First Anniversary Payment. Following any exercise of an Opt-In Right for any of the six programs, the Company will be eligible to receive development, regulatory, and sales milestones from Apellis, as well as royalty payments on sales. The collaboration has an initial term of five years and may be extended up to two years on a per year and program-by-program basis. During the collaboration term, Apellis may, subject to certain limitations, substitute a specific complement gene and/or organ for any of the initial base editing programs. Apellis may terminate the Apellis Agreement for convenience on any or all of the programs by providing prior written notice. The Company received the $50.0 million upfront payment from Apellis in July 2021 and the $25.0 million First Anniversary Payment in June 2022. The Company accounts for the Apellis Agreement under ASC 606 as it includes a customer-vendor relationship as defined under ASC 606 and meets the criteria to be considered a contract. The overall transaction price as of the inception of the contract was determined to be $75.0 million, which is composed of the upfront payment of $50.0 million and the First Anniversary Payment of $25.0 million. The Company will re-evaluate the transaction price in each reporting period.The Company concluded that each of the six base editing programs combined with the research and development service, licenses, substitution rights and governance participation were material promises that were both capable of being distinct and were distinct within the context of the Apellis Agreement and represented separate performance obligations. Therefore, the Company did not recognize any upfront revenue related to the license. The Company further concluded that the Opt-In Rights and option to extend the collaboration term did not grant Apellis a material right. The Company determined that the term of the contract is five years, as this is the period during which both parties have enforceable rights.The selling price of each performance obligation was determined based on the Company’s estimated standalone selling price, or the ESSP. The Company developed the ESSP for all of the performance obligations included in the Apellis Agreement by determining the total estimated costs to fulfill each performance obligation identified with the objective of determining the price at which it would sell such an item if it were to be sold regularly on a standalone basis. The Company allocated the stand-alone selling price to the performance obligations based on the relative standalone selling price method.The Company recognizes revenue for each performance obligation as it is satisfied over the five-year term using an input method. The Company allocated the transaction price of $75.0 million to each of the six performance obligations, which includes each of the six base editing programs combined with the research and development service, licenses, substitution rights and governance participation, and is being recognized using an input method based on the actual costs incurred as a percentage of total budgeted costs towards satisfying the performance obligation as this method provides the most faithful depiction of the entity’s performance in transferring control of the goods and services promised to Apellis and represents the Company’s best estimate of the period of the obligation. For the years ended December 31, 2023, 2022, and 2021, the Company recognized $16.4 million, $10.6 million and $1.8 million of revenue, respectively, related to the Apellis Agreement. As of December 31, 2023, there is $17.3 million and $28.9 million of current and long-term deferred revenue, respectively, related to the Apellis Agreement.Prime MedicineIn September 2019, the Company entered into a collaboration and license agreement with Prime Medicine to research and develop a novel gene editing technology developed by one of the Company’s founders. Under the terms of the agreement, the Company granted Prime Medicine a non-exclusive license to certain of its CRISPR technology (including Cas12b), delivery technology and certain other technology controlled by the Company to develop and commercialize gene editing products for the treatment of human diseases. Prime Medicine granted the Company an exclusive license to develop and commercialize prime gene editing technology for the creation or modification of any single base transition mutations, as well as any edits made for the treatment of sickle cell disease. For any products that use technology licensed from Prime Medicine, the Company is required to make milestone payments to Prime Medicine upon the achievement of certain clinical, regulatory and commercial events. It is also required to use commercially reasonable efforts to develop and seek regulatory approval for two products that use licensed technology from Prime Medicine in certain specified countries and to commercialize any such product(s) for which approval has been obtained in certain specified countries. Prime Medicine has an option to jointly develop and commercialize, and share expenses and revenue for, certain products that use technology licensed from Prime Medicine in the United States. Royalty payments may become due by either party to the other based on the net sales of commercialized products under the agreement.The Company had an obligation to issue $5.0 million in shares of its common stock to Prime Medicine, and Prime Medicine had an obligation to issue 5,000,000 shares of its common stock to the Company, should the Company elect to extend the collaboration beyond one year. In September 2020, the Company elected to continue the collaboration and, in October 2020, issued 200,307 shares of the Company’s common stock to Prime Medicine. Additionally, in October 2020, the Company received 5,000,000 shares of Prime Medicine’s common stock. In October 2022, Prime completed an initial public offering of its common stock. In connection with Prime's initial public offering, Prime effected a one-for-3.1088 reverse stock split. As of December 31, 2023, the Company owned 1,608,337 shares of Prime's common stock valued at $14.2 million.Additionally, the Company provided immaterial interim management and startup services to Prime Medicine through March 2021 but did not provide any such services during 2022 or 2023.As of December 31, 2023, the Company determined that future milestones and royalties under the agreement were not probable of recognition.VerveIn April 2019, the Company entered into a collaboration and license agreement with Verve, or the Verve Agreement, to investigate gene editing strategies to modify genes associated with an increased risk of coronary diseases and in July 2022, the Company and Verve amended the Verve Agreement. Under the terms of the Verve Agreement, as amended, the Company granted Verve an exclusive license to certain base editor technology and improvements and Verve granted the Company a non-exclusive license under certain know-how and patents controlled by Verve, an interest in joint collaboration technology and a non-exclusive license under certain delivery technology. In connection with the Verve Agreement, Verve issued the Company 2.6 million shares of its common stock as partial consideration for the licenses granted, having a fair value of $0.5 million. The fair value of the Verve common stock was determined by management with the assistance of a third-party valuation specialist. In addition, to the extent certain clinical, regulatory, and commercial milestones were met with respect to licensed products, Verve was required to pay to the Company certain amounts, as defined in the agreement. Lastly, to the extent there were sales of a licensed product, Verve was obligated to pay the Company royalties, as defined in the agreement.The Company also purchased shares of Verve's Series A preferred stock during the year ended December 31, 2020. During June 2021, Verve completed an initial public offering of its common stock. In connection with Verve’s initial public offering, Verve effected a one-for-9.2592 reverse stock split and also converted all shares of its preferred stock into shares of common stock. As of December 31, 2023, the Company owned 546,970 shares of Verve's common stock valued at $7.6 million.Management determined that the performance obligations associated with the Verve Agreement were the combined licenses and improvements related to the licensed technology. All other items promised to Verve were immaterial in the context of the agreement. The fair value of the shares issued by Verve to the Company were considered a fixed upfront payment of $0.5 million in the form of non-cash consideration. In October 2023, the Company, Verve, and Lilly entered into a Side Letter Agreement whereby the Company agreed to delegate to Lilly certain rights and obligations existing under the Verve Agreement, including the Company’s rights and obligations to co-develop and co-commercialize opt-in products, the financial rights to milestone and royalty payments, and the right to participate on certain joint decision-making committees. The Company determined that the transfer and delegation of rights represents a modification of the Verve Agreement to be accounted for as if it were part of the existing contract in accordance with ASC 606. Prior to the modification, the Company determined that its performance obligations associated with the Verve Agreement at contract inception and subsequent modifications were not distinct and represented a single performance obligation, and that the obligation would be completed over the performance period of the agreement. Accordingly, the upfront payment was being recognized as revenue using a time-based proportional performance model over the contract term (April 2019 through 2038) of the collaboration, as license revenue. The milestone payments and royalties were considered variable consideration and were constrained up until the modification date as no milestones or royalties were achieved. Subsequent to the modification, management concluded that the Company does not have material ongoing obligations to Verve in the arrangement and that the remaining revenue under the agreement should be recognized at a point-in-time upon modification. Therefore, the Company recognized the remaining $0.3 of unrecognized revenue in October 2023.For the year ended December 31, 2023, the Company recognized $0.4 of license revenue and has no remaining deferred revenue related to the Verve Agreement as of December 31, 2023. For each of the years ended December 31, 2022 and 2021, the Company recognized approximately $24,000 of license revenue.

million, respectively. At December 31, 2023, there was approximately $72.8 million of unrecognized stock-based compensation expense related to restricted stock that is expected to vest. These costs are expected to be recognized over a weighted-average remaining vesting period of approximately 2.2 years.2019 Employee Stock Purchase Plan In February 2020, the Company’s board of directors adopted the Beam Therapeutics Inc. 2019 Employee Stock Purchase Plan, or ESPP, which was approved by the Company’s stockholders. Pursuant to the ESPP, certain employees of the Company, excluding consultants and non-employee directors, are eligible to purchase common stock of the Company at a reduced rate during offering periods. The ESPP permits participants to purchase common stock using funds contributed through payroll deductions, subject to a calendar year limit of $25,000 and at a purchase price of 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the applicable purchase date, which will be the final trading day of the applicable purchase period. The Company used the Black-Scholes option valuation model to estimate the fair value of the purchase right under the ESPP on the date of grant. The expected volatility is based on the historical volatility of the Company's common stock for a period of years corresponding with the expected life of the option. The risk-free interest rate is based on the U.S. Treasury yield curve at the time of grant for securities with a maturity period similar to the expected life of the option. The expected life is based on the term of the purchase period for the grants made under the ESPP.The Company uses the straight-line attribution approach to record the expense over the offering period. Stock-based compensation expense related to the ESPP for the years ended December 31, 2023, 2022 and 2021 was $1.3 million, $1.5 million, $0.3 million, respectively. The Company issued 130,403 and 70,073 shares under the ESPP during the years ended December 31, 2023 and 2022, respectively. There were no shares issued under the ESPP during the year ended December 31, 2021. As of December 31, 2023, the Company had 2,247,569 shares available for issuance under the ESPP.

In February 2020, the Company’s board of directors adopted the Beam Therapeutics Inc. 2019 Employee Stock Purchase Plan, or ESPP, which was approved by the Company’s stockholders. Pursuant to the ESPP, certain employees of the Company, excluding consultants and non-employee directors, are eligible to purchase common stock of the Company at a reduced rate during offering periods. The ESPP permits participants to purchase common stock using funds contributed through payroll deductions, subject to a calendar year limit of $25,000 and at a purchase price of 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the applicable purchase date, which will be the final trading day of the applicable purchase period.

14. Net loss per share attributable to common stockholders As noted above, for periods in which the Company reports a net loss attributable to common stockholders, potentially dilutive securities have been excluded from the computation of diluted net loss per share as their effects would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at period end, from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect:<div style="font-size:12pt;font-family:Times New Roman;"> <table

respectively, which reflects that Company generated taxable income that was not fully offset by the use of net operating loss carryforwards and tax credits. Management has evaluated the positive and negative evidence bearing upon the realizability of the Company’s deferred tax assets and has determined that it is more likely than not that the Company will not recognize the benefits of the deferred tax assets. As a result, the Company has recorded a full valuation allowance at December 31, 2023 and 2022. The valuation allowance increased by $75.0 million in 2023 due to the increase in deferred tax assets, primarily due to increased capitalization of research and development expenditures in 2023. The valuation allowance increased by $82.3 million in 2022.Additionally, Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, limit a corporation’s ability to utilize tax attributes to the extent the corporation experiences an “ownership change,” generally defined as a greater than 50 percentage point change in ownership, measured by value, among 5% or greater shareholders over a rolling three-year testing period. To the extent a corporation experiences an ownership change, utilization of pre-ownership change tax attributes (e.g., net operating losses and general business tax credits) to offset post-ownership change taxable income or taxes, is subject to an annual limitation, generally calculated as the pre-ownership change equity value of the corporation, subject to certain prescribed adjustments, multiplied by the long-term tax exempt rate published monthly by the Internal Revenue Service. The Company completed a Section 382 study as of December 31, 2023, and determined that historical ownership changes occurred in June 2017, December 2018, and December 2021. In addition, the Company may experience ownership changes in the future as a result of shifts in stock ownership. As of December 31, 2023 and 2022, the Company had $16.6 million and $120.3 million, respectively, of federal net operating loss carryforwards that do not expire. Additionally, as of December 31, 2023, the Company had $41.3 million of federal and $19.5 million of Massachusetts tax credits that expire starting in 2042 and 2037.As of December 31, 2023, and 2022, the Company had no uncertain tax positions. The Company recognizes both interest and penalties associated with unrecognized tax benefits as a component of income tax expense. The Company has not recorded any interest or penalties for unrecognized tax benefits since its inception.The Company filed income tax returns in the United States and the Commonwealth of Massachusetts in all tax years since inception. Tax years beginning in 2020 remain open to examination in these jurisdictions, as carryforward attributes generated in past years may be adjusted in a future period. The IRS has not made any assessments as of December 31, 2023.

A reconciliation of the income tax expense computed using the federal statutory income tax rate to the Company’s effective income tax rate is as follows: <table
