Notes to Condensed Consolidated Financial Statements (Unaudited)

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 resources

Since 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 is also in the process of developing 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 an at the market, or ATM, 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. Between April and July 2021, the Company 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, the Company and Jefferies entered into an amendment to the Sales Agreement to provide for an increase in the aggregate offering amount under the Sales Agreement, such that as of July 7, 2021, the Company may offer and sell shares of common stock having an aggregate offering price of an additional $500.0 million. As of September 30, 2022, the Company has sold 3,248,633 additional shares of its common stock under the amended Sales Agreement at an average price of $89.06 per share for aggregate gross proceeds of $289.3 million, before deducting commissions and offering expenses payable by the Company.

Since its inception, the Company has incurred substantial losses and had an accumulated deficit of $1.0 billion as of September 30, 2022. 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 September 30, 2022 of $1.1 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.

COVID-19-related significant risks and uncertainties

With the ongoing concerns related to the COVID-19 pandemic, the Company has maintained its business continuity plans to address and mitigate the impact of the COVID-19 pandemic on its business. In March 2020, to protect the health of its employees, and their families and communities, the Company restricted access to its offices to personnel who performed critical activities that must be completed on-site, limited the number of such personnel that could be present at its facilities at any one time, and requested that most of its employees work remotely. In May 2021, as certain states eased restrictions, the Company established new protocols to better allow its full laboratory staff access to the Company’s facilities. These protocols included several shifts working over a seven-day-week protocol. In June 2021, as certain states continued to ease restrictions, the Company started to allow its entire workforce the ability to work on-site at the Company’s facilities, with fewer restrictions, particularly for vaccinated employees.

The Company expects to continue incurring additional costs to ensure it adheres to the guidelines instituted by the Centers for Disease Control and Prevention and to provide a safe working environment to its onsite employees.

The extent to which the COVID-19 pandemic impacts the Company’s business, its corporate development objectives, results of operations and financial condition, and the value of and market for its common stock, will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, social distancing and business closure requirements, and the effectiveness of actions taken globally to contain and treat the disease. Disruptions to the global economy and supply chain, disruption of global healthcare systems, and other significant impacts of the COVID-19 pandemic could have a material adverse effect on the Company’s business, financial condition, results of operations and growth prospects.

While the COVID-19 pandemic did not significantly impact the Company’s business or results of operations during the three or nine months ended September 30, 2022, the length and extent of the pandemic, its consequences, and containment efforts will determine the future impact on the Company’s operations and financial condition.

2. Summary of significant accounting policies

The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2021, and notes thereto, which are included in the Company’s Annual Report on Form 10-K that was filed with the Securities and Exchange Commission, or the SEC, on February 28, 2022, or the 2021 Form 10-K. Since the date of those financial statements, there have been no material changes to Beam’s significant accounting policies except with respect to equity method accounting as described below.

Basis of presentation

The accompanying condensed 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.

Principles of consolidation

The accompanying condensed 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.

Use of estimates

The 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 condensed consolidated financial statements include, but are not limited to, incremental borrowing rate used in the calculation of lease liabilities, research and development expenses, stock-based compensation, contingent consideration liabilities, success payments and certain judgements regarding revenue recognition. Actual results could differ from these estimates.

Cash, cash equivalents, and restricted cash

Cash and cash equivalents consist of standard 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 corporate and manufacturing facilities.

The following table reconciles cash, cash equivalents, and restricted cash reported within the Company’s condensed consolidated balance sheets to the total of the amounts shown in the condensed consolidated statements of cash flows (in thousands):


	September 30, 2022		September 30, 2021
Cash and cash equivalents	$	156,511	$	612,023
Restricted cash		12,750		14,840
Total cash, cash equivalents, and restricted cash	$	169,261	$	626,863

Equity method of accounting

In 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, 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.

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 September 30, 2022, the Company accounted for its investment in Orbital Therapeutics, Inc., or Orbital, under the equity method of accounting. Refer to Note 8 for further details.

Cash equivalents – Money market funds included within cash equivalents are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. Commercial paper and corporate notes are classified within Level 2 of the fair value hierarchy because pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies.

Marketable securities – Marketable securities, excluding corporate equity securities, are classified within Level 2 of the fair value hierarchy because pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined using models or other valuation methodologies.

The Company holds an investment in Verve consisting of shares of Verve’s common stock. Prior to Verve's initial public offering in June 2021, the Company valued such investment based on the cost of the equity securities adjusted for any observable market transactions. Following Verve's initial public offering, the equity securities have a readily determinable fair value. As of September 30, 2022, the Company owned 546,970 shares of Verve's common stock valued at $18.8 million, which is included in marketable securities in the condensed consolidated balance sheet.

The following table summarizes other income (expense) incurred due to changes in the fair value of corporate equity securities held (in thousands):


	Three Months Ended September 30,					Nine Months Ended September 30,
	2022		2021			2022			2021
Other income (expense)	$	10,431	$	(4,892	)	$	(1,378	)	$	21,960

Pursuant to ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, the Company records changes in the fair value of its investments in equity securities to other income (expense), in the Company’s condensed consolidated statements of operations.

Success payment liabilities – As discussed further in Note 10, License agreements, the Company is required to make payments to Harvard and Broad Institute based upon the achievement of specified multiples of the initial weighted average value of the Company’s Series A Preferred Stock or, subsequent to the Company’s initial public offering, or IPO, the market value of the Company's common stock, at specified valuation dates. The Company’s liability for the share-based success payments under the Harvard and Broad License Agreements is carried at fair value. To determine the estimated fair value of the success payment liability, the Company uses a Monte Carlo simulation methodology, which models the future movement of stock prices based on several key variables.

The following variables were incorporated in the calculation of the estimated fair value of the Harvard and Broad Institute success payment liabilities:


	Harvard						Broad Institute
	September 30, 2022			December 31, 2021			September 30, 2022			December 31, 2021
Fair value of common stock (per share)	$	47.64		$	79.69		$	47.64		$	79.69
Expected volatility		82	%		76	%		82	%		76	%
Expected term (years)	0.09-6.75			0.10-7.49			0.09-7.61			0.10-8.36

The computation of expected volatility was estimated using available information about the historical volatility of stocks of similar publicly traded companies in addition to the Company's own data for a period matching the expected term assumption. In addition, the Company incorporated the estimated number, timing, and probability of valuation measurement dates in the calculation of the success payment liability.

The following table reconciles the change in the fair value of success payment liabilities based on Level 3 inputs (in thousands):


	Nine Months Ended September 30, 2022
	Harvard			Broad Institute			Total
Balance at December 31, 2021	$	21,000		$	21,200		$	42,200
Change in fair value		(10,500	)		(10,400	)		(20,900	)
Balance at September 30, 2022	$	10,500		$	10,800		$	21,300

Contingent consideration liabilities – As discussed further in Note 9, Guide acquisition, under the Guide Merger Agreement, 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 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 in 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.

The following table reconciles the change in fair value of the contingent consideration liabilities based on level 3 inputs (in thousands):


	Nine Months Ended September 30, 2022
	Technology Milestones		Product Milestones			Total

The amortized cost of marketable securities is adjusted for amortization of premiums and accretion of discounts to maturity. At September 30, 2022, the balance in accumulated other comprehensive (loss) income was comprised solely of activity related to marketable securities. There were no realized gains or losses recognized on the sale or maturity of marketable securities for the three or nine months ended September 30, 2022 and 2021 and, as a result, the Company did not reclassify any amounts out of accumulated other comprehensive (loss) income for the same periods.

The Company holds debt securities of companies with high credit quality and has determined that there was no material change in the credit risk of any of its debt securities. The contractual maturity dates of all the investments are less than one year.

6. Accrued expenses and other current liabilities

Accrued expenses and other current liabilities consist of the following (in thousands):


	September 30, 2022		December 31, 2021
Employee compensation and related benefits	$	12,004	$	11,661
Research costs		5,363		3,133
Professional fees		3,543		3,330
Process development and manufacturing costs		4,601		3,833
Other		13,089		6,964
Total	$	38,600	$	28,921

The Company recently received correspondence from a research institution regarding a confidentiality agreement between such institution and the Company. The confidentiality agreement related to certain technology that the Company evaluated for development in connection with certain of its programs. The correspondence alleges that the Company breached the terms of the confidentiality agreement, misappropriated trade secret and other confidential information of such institution, engaged in unfair and deceptive trade practices, and was unjustly enriched in connection with developing its therapeutics, including BEAM-102 and the Company’s Alpha-1 Antitrypsin Deficiency therapeutic candidate (which the Company now refers to as BEAM-302). The research institution claims that it is entitled to monetary damages (including damages for the apportioned value of the Company and enhanced damages for an alleged willful violation) and certain ongoing royalty and/or milestone payments related to the technology that is the subject of the alleged breaches of contract, among other possible remedies.

As of September 30, 2022, the Company has accrued a $3.4 million liability equal to an amount the Company offered to resolve the dispute. The settlement proposal was rejected by the research institution. No complaint has been filed, and the Company continues to discuss the matter with the research institution. Although it may do so, the Company has not determined to make a further offer and believes that it is unable at this time to provide any estimate of a reasonably possible loss in excess of the amount offered. The ultimate resolution of this matter could result in an outcome that is materially different from the amount accrued as of September 30, 2022.

7. Leases

Operating leases

The Company’s operating leases are as follows:

•

A February 2018 lease for 38,203 square feet of office and laboratory space, which commenced in March 2018 and terminates in September 2028. The lease is subject to fixed-rate rent escalations and provided for $6.1 million in tenant improvements and a term extension option, which is not reasonably certain of exercise.

•

An October 2018 lease for laboratory space as amended, which commenced in April 2019 and terminates in December 2025. The amended lease is subject to fixed-rate rent escalations and provides an option to extend the lease for two additional two-year periods through December 31, 2029, which are not reasonably certain of being exercised. Through September 30, 2022, the Company has recorded ROU assets and lease liabilities of $14.1 million and $14.0 million related to this lease.

•

An April 2019 lease for office and laboratory space that was built over the course of 2020 and 2021. Pursuant to the terms of the original lease agreement, the first phase of the lease commenced in October 2020 (rent payments for the first phase began in August 2021) and the second phase of the lease commenced in January 2021 (rent payments for the second phase began in February 2022). The lease is subject to fixed-rate rent escalations and provides for $23.4 million in tenant improvements and the option to extend the lease for two terms of five years each, which are not reasonably certain of exercise. The Company determined that it is the accounting owner of all tenant improvements. The Company maintains a security deposit of $9.7 million in the form of a letter of credit, which is included in restricted cash as of September 30, 2022 and December 31, 2021. Upon commencement of the first phase of this lease in October 2020, the Company recorded an operating lease ROU asset of $66.8 million and a lease liability of $68.8 million and upon commencement of the second phase of this lease in January 2021, the Company recorded an operating lease ROU asset of $22.0 million and a corresponding lease liability of $23.0 million. Subsequently, during the second quarter of 2021, the Company amended the rent commencement dates of the first and second phases of this lease. Pursuant to the terms of the amendment, the lease will terminate in February 2034, which is 12 years from the amended second phase rent commencement date. As a result, the Company recorded an increase in the ROU asset of $0.5 million and lease liability of $0.5 million.

•

An August 2020 lease for a 100,000 square foot manufacturing facility in Research Triangle Park, North Carolina. Construction of the manufacturing facility began in 2020 and the Company expects to begin making rent payments in the first quarter of 2023. The lease will terminate 15 years from the rent commencement date. The lease is subject to fixed-rate rent escalations and provides for $20.0 million in tenant improvements and the option to extend the lease for two terms of five years each, which were not reasonably certain of exercise as of September 30, 2022. The Company determined that it is the accounting owner of all tenant improvements under the lease. Upon executing the lease in August 2020, the Company made a security deposit of $1.5 million in the form of a letter of credit, which is included in restricted cash as of September 30, 2022 and December 31, 2021. Upon commencement of this lease in June 2022, the Company recorded an operating lease ROU asset of $13.6 million and a lease liability of $30.4 million. The variance between the ROU asset and lease liability recorded relates to $16.8 million of tenant improvement allowance completed through the lease commencement date. The $16.8 million of tenant improvement allowance is presented as an operating cash inflow and investing cash outflow within the Company’s condensed consolidated statements of cash flows. The rent payments are subject to adjustment following the determination of the total project costs of the landlord and represent in substance fixed payments that are included in the total future minimum lease payments.

In August 2021, the Company executed a lease amendment to its April 2019 lease for office and laboratory space in Cambridge, Massachusetts to occupy additional space. The term of this lease will run concurrent with the term of the April 2019 lease. The initial estimate of the minimum amount of undiscounted lease payments due under this lease is $11.1 million. As the lease had not yet commenced as of September 30, 2022, the Company has not recorded an operating lease ROU asset or lease liability for this lease in the accompanying condensed consolidated balance sheets. The tabular disclosure of minimum lease payments above does not include payments due under this lease.

8. Equity method investment

Orbital

In September 2022, the Company entered into a License and Research Collaboration Agreement, or the Orbital Agreement, with Orbital Therapeutics, Inc., or Orbital, a newly formed entity, focused on advancing non-viral delivery and RNA technologies (See Note 11). In exchange for contributing exclusive and non-exclusive licenses and certain services, the Company received a 31.5% fully diluted equity interest in Orbital at the time of closing pursuant to a Common Stock Issuance Agreement, or the Orbital Issuance Agreement, as well as certain exclusive and non-exclusive licenses from Orbital. As of the closing date Beam held 97.0% of the outstanding common stock of Orbital. Additionally, certain members of the Company's executive team are providing interim management services to Orbital under separate agreements between Orbital and the executives. Orbital is not compensating the Company for the interim management services.

The Company has significant influence over, but does not control, Orbital through its noncontrolling representation on Orbital’s board of directors and the Company’s equity interest in Orbital. The Company determined that Orbital is a variable interest entity because it does not have sufficient equity at risk to finance its operations without additional subordinated financial support. The Company is not the primary beneficiary as it does not have the power to direct activities that most significantly impact Orbital’s economic performance. 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, the fair value of the Company’s investment in Orbital was $25.5 million, which represents the fair value of the common stock received under the Orbital Issuance Agreement (See Note 11). 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%). After its initial investment, the Company will adjust the carrying value of its investment in Orbital by its proportionate share of Orbital’s net loss based on the Company’s share, of Orbital’s outstanding common stock and in-substance common stock.

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, and therefore the carrying value of the equity method investment will not be reduced below zero. For the three and nine months ended September 30, 2022, the Company

recognized a loss from its equity method investment of $25.5 million in association with the basis difference charge in the Company’s condensed consolidated statements of operations.

The maximum exposure to loss is limited to the Company’s equity investment in Orbital, which has a carrying value of zero at September 30, 2022. To date the Company has not received any dividends from Orbital.

9. Guide acquisition

On 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, Business Combinations, 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 accompanying condensed 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 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 contingent consideration 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 condensed consolidated statements of operations and other comprehensive loss, presented within other income (expense).

The transaction price was determined and allocated as follows (in thousands):


Transaction price
Fair value of equity instruments issued	$	120,032
Technology and product contingent consideration liabilities		36,513
Transaction costs		2,531
Total transaction price	$	159,076

Change in fair value of Broad Institute success payment liability	$	2,500	$	(17,900	)	$	(10,400	)	$	4,200

The annual maintenance fee under the Broad License Agreement is recorded as research and development expense. Annual patent costs will be expensed as incurred. As of September 30, 2022, the Company determined that product development and regulatory

approval milestones and royalties under the Broad License Agreement were not probable and, as such, no amounts were recognized for the three and nine months ended September 30, 2022. There was no expense recorded for these milestones for the three and nine months ended September 30, 2022 or 2021.

The Company paid $6.1 million of non-royalty sublicense fees to Broad Institute during the nine months ended September 30, 2022 related to non-royalty sublicense fee expense incurred during the second half of 2021.

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.

The annual maintenance fees under the Editas License Agreement are recorded as research and development expense. 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.

Management concluded that the licenses acquired from each transaction above did not meet the accounting definition of a business as inputs, but no processes or outputs were acquired with the licenses, and the licensed technology had not achieved technological feasibility. As the inputs that were acquired along with the licenses do not constitute a “business,” the transactions have been accounted as asset acquisitions.

11. Collaboration and license agreements

Orbital

In September 2022, the Company entered into the Orbital Agreement and the Orbital Issuance Agreement with Orbital. Under the terms of the Orbital Agreement, the Company will collaborate with Orbital to advance nonviral delivery and 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 Beam 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, which represents a 31.5% fully diluted equity interest in Orbital. The Company accounts for its investment in Orbital under the equity method of accounting. Refer to Note 8 for further details.

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 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. See Note 8 for the determination of the fair value of the Company’s investment. There is no variable consideration included in the transaction price at inception.

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 has 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 plans to recognize revenue for the performance obligation over time as it is satisfied during the term of the agreement. As no activities under the Orbital Agreement had commenced as of September 30, 2022, the entire $25.5 million is recorded as deferred revenue and no revenue was recognized during the three and nine months ended September 30, 2022. Based on the current estimated timelines, the deferred revenue is expected to be

recognized as revenue over approximately three years from September 30, 2022. As of September 30, 2022, there was $8.5 million and $17.0 million of current and long-term deferred revenue, respectively, related to the Orbital Agreement.

Pfizer

In 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 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 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 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 Pfizer and represents the Company’s best estimate of the period of the obligation. For the three and nine months ended September 30, 2022, the Company recognized $12.8 million and $33.4 million of revenue related to the Pfizer Agreement, respectively. As of September 30, 2022, there was $123.6 million and $143.0 million of current and long-term deferred revenue, respectively, related to the Pfizer Agreement. There was no revenue recognized related to the Pfizer Agreement during the three or nine months ended September 30, 2021.

Apellis Pharmaceuticals

In 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 was eligible to receive a total of $75.0 million in upfront and near-term milestone payments from Apellis, which was comprised of $50.0 million received upon signing and an additional $25.0 million payment to be paid on the one-year anniversary of the effective date of the Apellis Agreement, or the First Anniversary Payment. The Company received the $25.0 million First Anniversary Payment from Apellis during the nine months ended September 30, 2022.

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 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 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 three and nine months ended September 30, 2022, the Company recognized $3.0 million and $7.5 million of revenue related to the Apellis Agreement, respectively. As of September 30, 2022, there is $27.8 million and $37.9 million of current and long-term deferred revenue, respectively, related to the Apellis Agreement. For the three and nine months ended September 30, 2021, the Company recognized $0.8 million of revenue related to the Apellis Agreement.

Prime Medicine

In September 2019, the Company entered into a collaboration and license agreement, or the Prime Agreement, with Prime Medicine, Inc., or Prime, 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. Additionally, each party granted to the other party certain exclusive and non-exclusive licenses to certain technology developed after the effective date of the agreement and controlled by the granting party or jointly owned by the parties. Each party has an obligation to assign rights in certain technology developed under the collaboration to the other party.

The Company provided immaterial interim management and startup services to Prime Medicine through March 2021 but did not provide any such services during 2022.

As of September 30, 2022, the Company determined that future milestones and royalties under the Prime Agreement were not probable of recognition.

Verve

In 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 Beam 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.

As of September 30, 2022, the Company determined that milestones and royalties under the Verve Agreement were not probable of recognition.

At September 30, 2022, there was approximately $98.3 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 3.2 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 ESPP has two annual purchase periods extending from October to March and April to September.

The Company issued 41,083 and 70,073 shares under the ESPP during the three and nine months ended September 30, 2022, respectively. There were no shares issued under the ESPP during the nine months ended September 30, 2021. As of September 30, 2022, the Company had 1,665,199 shares available for issuance under the ESPP.

Stock-based compensation recognized under the ESPP for the three and nine months ended September 30, 2022 was $0.2 million and $1.1 million, respectively. There was no stock-based compensation expense recorded under the ESPP for the three and nine months ended September 30, 2021.

14. Net loss per share

For periods in which the Company reports a net loss, 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 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 because including them would have had an anti-dilutive effect:


	As of September 30,
	2022		2021
Unvested restricted stock		1,647,779		1,286,834
Outstanding options to purchase common stock		7,607,063		6,139,250
Total		9,254,842		7,426,084

The following table summarizes the computation of basic and diluted net loss per share of the Company (in thousands, except share and per share amounts):

15. Income taxes

During the three and nine months ended September 30, 2022, the Company recorded an income tax provision of $2.4 million. During the three and nine months ended September 30, 2021, the Company did not record a tax provision. The income tax provision for the period ended September 30, 2022 is primarily attributable to the recognition of revenue for tax purposes under the collaboration agreements with Apellis and Pfizer, which was deferred in 2021 for tax purposes. In addition, the Tax Cuts and Jobs Act of 2017 eliminates the option to deduct research and development expenditures currently and requires taxpayers to capitalize and amortize them over five or fifteen years pursuant to Section 174 of the Internal Revenue Code of 1986, as amended.

Utilization of the net operating loss, or NOL, and research and development credit carryforwards may be subject to a substantial annual limitation under Section 382 and 383 of the Internal Revenue Code due to ownership change limitations that have occurred previously, or that could occur in the future. These ownership changes may limit the amount of net operating loss and research and development credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. The Company has completed a Section 382 study as of December 31, 2021. As of December 31, 2021 the Company had $374.4 million of federal net operating losses available, subject to an 80% limitation.

The Company evaluates the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. A significant piece of objective evidence evaluated was the cumulative loss incurred over the three-year period ended June 30, 2022 and that the Company has historically generated pretax losses. Such objective evidence limits the ability to consider other subjective evidence, such as projections for future growth. On the basis of this evaluation, as of June 30, 2022, the Company continued to maintain a full valuation allowance against its deferred tax assets, except to the extent NOLs have been used to reduce taxable income.

Overview

We are a biotechnology company committed to establishing the leading, fully integrated platform for precision genetic medicines. Our vision is to provide life-long cures to patients suffering from serious diseases. To achieve this vision, we have assembled a platform that includes a suite of gene editing and delivery technologies and are in the process of developing internal manufacturing capabilities.

Our suite of gene editing technologies is anchored by our proprietary base editing technology, which potentially enables a differentiated class of precision genetic medicines that target a single base in the genome without making a double-stranded break in the DNA. This approach uses a chemical reaction designed to create precise, predictable and efficient genetic outcomes at the targeted sequence. Our proprietary base editors have two principal components: (i) a clustered regularly interspaced short palindromic repeats, or CRISPR, protein, bound to a guide RNA, that leverages the established DNA-targeting ability of CRISPR, but is modified to not cause a double-stranded break, and (ii) a base editing enzyme, such as a deaminase, which carries out the desired chemical modification of the target DNA base. We believe this design contributes to a more precise and efficient edit compared to traditional gene editing methods, which operate by creating targeted double-stranded breaks in the DNA that can result in unwanted DNA modifications. We believe that the precision of our editors will dramatically increase the impact of gene editing for a broad range of therapeutic applications.

To unlock the full potential of our base editing technology across a wide range of therapeutic applications, we are pursuing a broad suite of both clinically validated and novel delivery modalities, depending on tissue type, including: (1) electroporation for efficient delivery to blood cells and immune cells ex vivo; (2) lipid nanoparticles, or LNPs, for non-viral in vivo delivery to the liver and potentially other organs in the future; and (3) adeno-associated viral vectors, or AAV, for in vivo viral delivery to the eye and potentially other organs.

The elegance of the base editing approach combined with a tissue specific delivery modality provides the basis for a targeted, efficient, precise, and highly versatile gene editing system, capable of gene correction, gene modification, gene silencing or gene activation, and/or multiplex editing of several genes simultaneously. We are currently advancing a broad, diversified portfolio of base editing programs against distinct editing targets, utilizing the full range of our development capabilities.

Furthermore, in addition to our portfolio, we are also pursuing an innovative, platform-based business model with the goal of further expanding our access to new technologies in genetic medicine and increasing the reach of our programs to more patients. Overall, we are seeking to build the leading integrated platform for precision genetic medicine, which may have broad therapeutic applicability and the potential to transform the field of precision genetic medicines.

Ex Vivo HSCs: Sickle cell disease and beta-thalassemia

We are advancing ex vivo base editing programs in which hematopoietic stem cells, or HSCs are collected from a patient, edited using electroporation, a clinically validated technology for the delivery of therapeutic constructs into harvested cells. These cells are infused back into the patient following a myeloablative conditioning regimen, such as treatment with busulfan, the standard of care in HSC transplantation today. Once reinfused, the HSCs begin repopulating a portion of the bone marrow in a process known as engraftment. The engrafted, edited HSCs give rise to progenitor cell types with the corrected gene sequences.

We are pursuing a long-term, staged development strategy for our base editing approach to treat sickle cell disease that consists of advancing our ex vivo programs, BEAM-101 and BEAM-102, in Wave 1, improving patient conditioning regimens in Wave 2, and enabling in vivo base editing with delivery directly into HSCs of patients via LNPs in Wave 3. We believe this suite of technologies – base editing, improved conditioning and in vivo delivery for editing HSCs – can maximize the potential applicability of our sickle cell disease programs to patients as well as create a platform for the treatment of many other severe genetic blood disorders.

Wave 1: Ex Vivo Base Editing via Autologous Transplant with BEAM-101 and BEAM-102

We are using base editing to pursue the development of two complementary approaches to treating sickle cell disease, a severe inherited blood disease caused by a single point mutation, E6V, in the beta globin gene (BEAM-101 and BEAM-102), and one approach to treat beta-thalassemia, another inherited blood disorder characterized by severe anemia caused by reduced production of functional hemoglobin due to insufficient expression of the beta globin protein (BEAM-101).

BEAM-101: Recreating naturally-occurring protective mutations to activate fetal hemoglobin

BEAM-101 is an investigational, patient-specific, autologous hematopoietic cell therapy which is designed to incorporate ex vivo base edits that mimic single nucleotide polymorphisms seen in individuals with hereditary persistence of fetal hemoglobin, or HPFH, to potentially alleviate the effects of mutations causing sickle cell disease or beta thalassemia. Our Investigational New Drug, or IND, application for BEAM-101 for the treatment of sickle cell disease has been cleared by the U.S. Food and Drug Administration, or FDA, and we are preparing to initiate a Phase 1/2 clinical trial designed to assess the safety and efficacy of BEAM-101 for the treatment of sickle cell disease, which we refer to as our BEACON trial. The BEACON trial is expected to include an initial “sentinel” cohort of three patients, treated one at a time to confirm successful engraftment, followed by dosing in up to a total of 45 patients. The clinical trial is designed to initially include patients between ages 18 and 35 with sickle cell disease who have received prior treatment with at least one disease-modifying agent with inadequate response or intolerance. Following mobilization, conditioning and HSC transplant with BEAM-101, patients will be assessed for safety and tolerability, with safety endpoints including the proportion of patients with successful neutrophil engraftment by day 42. Patients will also be assessed for efficacy, with efficacy endpoints including the change from baseline in severe vaso-occlusive events, transfusion requirements, hemoglobin F levels, and quality of life and ability to function. We have activated multiple U.S. clinical trial sites and are recruiting patients for the BEACON trial. We expect to enroll the first subject in the BEACON trial by the end of 2022.

We have achieved proof-of-concept in vivo with long-term engraftment of base edited human CD34 cells in mice administered BEAM-101. Persistence of engraftment and high levels of editing have been confirmed in several preclinical studies, including in studies using material generated at a clinically relevant scale.

BEAM-102: Direct correction of the sickle cell mutation

Our second ex vivo base editing approach that we are developing for sickle cell disease, BEAM-102, is designed to directly correct the causative sickle mutation at position 6 of the beta globin gene. By making a single A-to-G edit, we have demonstrated in primary human CD34+ cells isolated from sickle cell disease patients the ability to create the naturally occurring HbG or “Makassar” variant of hemoglobin. This variant, which was identified in humans and first published in 1970, has the same function as the wild-type variant and does not cause sickle cell disease. Distinct from other approaches, cells that are successfully edited in this way are fully corrected, no longer containing the sickle protein.

During the second quarter of 2020, we published preclinical data on BEAM-102 demonstrating that our adenine base editors, or ABEs, can efficiently convert the causative Hemoglobin S, or HbS, point mutation, to HbG-Makassar, with high efficiency (more than 80%). In this preclinical study, the Makassar variant does not cause hemoglobin to polymerize and red blood cells to sickle and, therefore, edited cells are cured through elimination of the disease-causing protein. In December 2021, we presented data from preclinical studies further characterizing the Makassar hemoglobin created by BEAM-102 and demonstrating biophysical and biochemical properties consistent with normal hemoglobin.

We have decided not to submit an IND for BEAM-102 in 2022 and to optimize our direct correction, “Makassar” approach, alongside our HPFH approach, for Wave 2 and Wave 3 of our sickle cell disease programs.

Wave 2: Improved Conditioning

In parallel with Wave 1 development, we also aim to improve the transplant conditioning regimen for sickle cell disease patients undergoing HSC transplantation, or HSCT, reducing toxicity challenges associated with HSCT standard of care. Conditioning is a critical component necessary to prepare a patient’s body to receive the ex vivo edited cells that must engraft in the patient’s bone marrow in order to be effective. Today’s conditioning regimens rely on nonspecific chemotherapy or radiation, which are associated with significant toxicities. We are collaborating with Magenta Therapeutics, Inc., or Magenta, to evaluate the potential utility of MGTA-117, Magenta’s novel antibody drug conjugate, in combination with BEAM-101 and BEAM-102, as well as other base editing programs in hematology. MGTA-117 is designed to spare immune cells and precisely target hematopoietic stem and progenitor cells, or HSPCs, and has demonstrated high selectivity, potent efficacy, wide safety margins and broad tolerability in non-human primate, or NHP, models. We are also conducting our own research into novel conditioning strategies. In June 2022, we presented preclinical research highlighting our internal efforts to develop improved transplant conditioning regimens for patients with sickle cell disease undergoing HSCT. We leveraged our base editing capabilities to develop a potentially non-genotoxic approach that combines antibody-based conditioning with multiplex gene edited hematopoietic stem cells called ESCAPE, or Engineered Stem Cell Antibody Paired Evasion. These improved conditioning regimens could potentially be paired with BEAM-101 and BEAM-102, as well as other base editing programs in hematology.

Wave 3: In Vivo Base Editing via HSC-targeted LNPs

We are also exploring the potential for in vivo base editing programs for sickle cell disease, in which base editors would be delivered to the patient through an infusion of LNPs targeted to HSCs, eliminating the need for transplantation altogether. This approach could provide a more accessible option for patients, particularly in regions where ex vivo treatment is challenging. Building on our acquisition of Guide, we are using our proprietary DNA-barcoded LNP screening technology to enable high-throughput in vivo identification of LNPs with novel biodistribution and selectivity for target organs beyond the liver. In December 2021, we announced we had screened more than 1,000 LNPs using this technology for potential to deliver to HSCs and had identified LNP-HSC1 as the most potent, with efficient transfection in both mice and NHPs.

Achieving Understanding of the Natural History of Sickle Trait (AUNT) Study

In May 2022, we announced the initiation of a sickle cell trait, or SCT, focused natural history study. Carriers of sickle cell disease, or those with SCT, have only one copy of the hemoglobin gene, have HbS levels between 25-45%, and are thought to have a benign condition. However, despite SCT impacting approximately 300 million people around the world, the key hematologic and clinical phenotypic characteristics and functional impacts from having SCT have been understudied in a prospective manner. As part of a long-term lifecycle strategy for our sickle cell disease programs, we, in collaboration with the National Alliance of Sickle Cell Centers, the University of Alabama, and Johns Hopkins Medical Center, have initiated the AUNT (Achieving Understanding of the Natural History of Sickle Trait) Study.

The AUNT Study is designed to establish an understanding of the hematologic and clinical phenotype of people with SCT, including blood rheology, potential complications and genetic modifiers, in an effort to better understand the hematologic phenotype that is associated with good health and lack of organ dysfunction. The study is designed to enroll approximately 1,000 participants with SCT in the United States who have been identified as family members of participants in the Global Research Network for Data and Discovery, a multi-institutional prospective registry comprising clinical and background data from more than 1,200 adult and pediatric individuals with sickle cell disease from 1999-2021.

Ex vivo T cell therapies

The starting material for our multiplex-edited allogeneic CAR-T cell products is white blood cells from a healthy donor, which are collected using a standard blood bank procedure known as leukapheresis. Using a single electroporation, we introduce the base editor as mRNA, and the guides encoding the target sequences. The edited cells are subsequently transduced with a lentivirus expressing the CAR. Once the T cells have been engineered, they are expanded and frozen. After the patient is lymphodepleted, the multiplex-edited, allogeneic cell product is infused.

We believe base editing is a powerful tool to simultaneously multiplex edit many genes without the unintended on-target effects that can result from simultaneous editing with nucleases through the creation of double-stranded breaks. The ability to create a large number of multiplex edits in T cells could endow CAR-T cells and other cell therapies with combinations of features that have the potential to dramatically enhance their therapeutic potential in treating hematological or solid tumors.

The initial indications that we plan to target with our chimeric antigen receptor T-cell, or CAR-T, product candidates are relapsed, refractory T-cell acute lymphoblastic leukemia /T cell lymphoblastic lymphoma, or T-ALL/T-LL, a severe disease affecting children and adults, and Acute Myeloid Leukemia, or AML. We believe that our approach has the potential to produce higher response rates and deeper remissions than existing approaches. Our proof-of-concept preclinical studies have demonstrated the ability of base editors to efficiently modify up to eight genomic loci simultaneously in primary human T cells with efficiencies ranging from 85-95% as measured by flow cytometry of target protein knockdown. Importantly, these results were achieved without the generation of observed chromosomal rearrangements, as evaluated by sensitive methods such as UDiTaSTM or G-banded Karyotyping and with no observed loss of cell viability from editing. The proof-of-concept preclinical studies have also demonstrated robust T cell killing of target tumor cells both in vitro and in vivo

BEAM-201: Universal CD7-targeting CAR-T cells

BEAM-201 is a development candidate comprised of T cells derived from healthy donors that are simultaneously edited at TRAC, CD7, CD52 and PDCD1 and then transduced with a lentivirus encoding for an anti-CD7 CAR that is designed to create allogeneic CD7 targeting CAR-T cells, resistant to both fratricide and immunosuppression. To our knowledge, BEAM-201 is the first investigational cell therapy featuring four simultaneous edits. At the end of June 2022, we submitted an IND to the FDA for BEAM-201 for the treatment of relapsed, refractory T-ALL/T-LL and potentially other CD7+ malignancies. In July 2022, the FDA informed us that the BEAM-201 IND was placed on clinical hold. We subsequently received a formal clinical hold letter from the FDA, in which the FDA requested: (i) additional control data from genomic rearrangement assessments; (ii) further analyses of certain off-target editing experiments; (iii) additional control data for a cytokine independent growth assay; and (iv) an updated investigator brochure that includes information regarding any new nonclinical studies. We submitted our response to the FDA in November 2022.

After Beam-201, we are focused on identifying the collection of multiplex base edits required to make cells fully allogeneic, with internal and external data suggesting a higher number of edits will be required to meet this goal. As a result, we do not expect to nominate a second CAR-T development candidate in 2022 and anticipate providing further updates in 2023.

CD5-targeting CAR-T cells

In October 2021, we announced preclinical data from our multiplex edited allogeneic CAR-T research program targeting CD5-positive hematologic malignancies. These data demonstrated knockout of CD5 expression to be a general mechanism to enhance potency and potentially improve durability of highly multiplexed CAR-T cells.

In vivo LNP

LNPs are a clinically validated technology for delivery of nucleic acid payloads to the liver. LNPs are multi-component particles that encapsulate the base editor mRNA and one or more guides and protect them from degradation while in an external environment, enabling the transient delivery of the base editor in vivo. Multiple third-party clinical trials have demonstrated the effective delivery of silencing RNA to the liver using LNPs. Because only one dose of a base editing therapy may be needed in a course of treatment, LNPs are a suitable delivery modality that we believe is unlikely to face the complications seen with chronic use of LNPs, such as those observed when delivering oligonucleotides or mRNA for gene therapy. All of the components of the LNP, as well as the mRNA encoding the base editor, are well-defined and can be manufactured synthetically, providing the opportunity for scalable manufacturing.

We have developed several proprietary LNP formulations. In May 2021, we announced initial data from our evaluation of various LNP formulations and mRNA production processes using an mRNA-encoding ABE and guide RNA to target the ALAS1 gene, a surrogate payload for genetic liver diseases. These data showed improved in vivo editing in the livers of NHPs from less than 10% initially to 52% at a total RNA dose of 1.5 mg/kg. Continued optimization of our LNP formulations has demonstrated further increases in liver editing potency in NHPs. In September 2021, we presented data demonstrating up to 60% editing in NHPs at a total RNA dose of 1.0 mg/kg. Data from our preclinical studies demonstrated that these formulations were well tolerated by NHPs treated with doses up to 1.5 mg/kg. Minimal to mild and transient liver enzyme elevations were observed and resolved by day 15 post-treatment. Additionally, the formulations showed promising interim stability, maintaining potency after three months at -20⁰C and -80⁰C.

We are currently using LNP formulations to advance our programs for genetic liver diseases, including Glycogen Storage Disease Type Ia, or GSDIa, also known as Von Gierke disease, and Alpha-1 Antitrypsin Deficiency, or AATD, and chronic hepatitis B infection. In November 2022, we nominated BEAM-302, a liver-targeting LNP formulation of base editing reagents designed to correct the E342K point mutation, which is most commonly responsible for AATD, as our second in vivo development candidate. We have also initiated IND-enabling studies for BEAM-301, a liver-targeting LNP formulation of base editing reagents designed to correct the R83C mutation, the most common disease-causing mutation of GSDIa.

Liver diseases: glycogen storage disorder 1a, alpha-1 antitrypsin deficiency, and chronic hepatitis B infection

GSDIa

GSDIa is an inborn disorder of glucose metabolism caused by mutations in the G6PC gene, which results in low blood glucose levels that can be fatal if patients do not adhere to a strict regimen of slow-release forms of glucose, administered every one to four hours (including overnight). There are no disease modifying therapies available for patients with GSDIa.

Our approach to treating patients with GSDIa is to apply base editing via LNP delivery to repair the two most prevalent mutations that cause the disease, R83C and Q347X. It is estimated that these two point mutations account for 900 and 500 patients, respectively, in the United States, representing approximately 59% of all GSDIa patients in the United States. Third party animal studies have shown that as little as 11% of normal G6Pase activity in liver cells is sufficient to restore fasting glucose; however, this level must be maintained in order to preserve glucose control and alleviate other serious, and potentially fatal, GSDIa sequelae.

In October 2021, we reported data from preclinical studies that support the potential of base editing to durably correct disease-causing mutations of GSDIa. We created a novel, humanized R83C knockout mouse model (huR83C), mimicking the abnormal metabolic phenotype of human GSDIa, and collaborated with the National Institutes of Health, or NIH, to characterize the phenotype of these animals. The results demonstrated that newborn huR83C mice treated with our LNP-delivered ABE exhibited normal growth to the end of the study at three weeks of age without any hypoglycemia-induced seizures. In contrast, homozygous animals were unable to survive soon after birth in the absence of glucose supplementation. In addition, we observed editing efficiencies up to approximately 60% by next-generation sequencing of DNA isolated from the whole liver.

In May 2022, an abstract announcing new preclinical data presented at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting was published. The data, which build on previously released preclinical results, demonstrated that in a GSDIa mouse model, treated mice, which otherwise have poor survival outcomes if left untreated, grew normally to at least 35 weeks following administration of BEAM-301, with survival ongoing in the study. Notably, as low as single digit percentage base-editing rates were sufficient to restore physiologically relevant levels of hepatic G6Pase activity, normalize serum metabolites and, most importantly,

prevent hypoglycemia during a twenty-four hour fast in treated mice. In addition, preliminary assessments of observed off-target editing have suggested a favorable profile of BEAM-301.

AATD

AATD is a severe inherited genetic disorder that can cause progressive lung and liver disease. The most severe form of AATD arises when a patient has a point mutation in both copies of the SERPINA1 gene at amino acid 342 position (E342K, also known as the PiZ mutation or the “Z” allele). With the high efficiency and precision of our base editors, we aim to utilize our ABEs to enable the programmable conversion of A-to-T and G-to-C base pairs and precisely correct the E342K point mutation back to the wild type sequence. In 2020, we showed the ability to directly correct the mutation causing AATD, providing both in vitro and in vivo preclinical proof-of-concept for base editing to correct this disease.

In May 2022, an abstract presented at ASGCT detailed our efforts to optimize both the ABE and the guide RNA used to correct the disease-causing PiZ mutation, with improvements over the original reagents leading to a greater than two-fold increase in observed editing potency and potentially therapeutically relevant increases in circulating alpha-1 antitrypsin in mice treated at doses that are expected to be clinically relevant (<1mg/kg). Further, similar results were observed in adult mice dosed at greater than 37 weeks, a treatment context more similar to what might be encountered in a clinical setting.

Hepatitis B Virus

Hepatitis B virus, or HBV, causes serious liver infection that can become chronic, increasing the risk of developing life-threatening health issues like cirrhosis, liver failure or liver cancer. Chronic HBV infection is characterized by the persistence of covalently closed circular DNA, or cccDNA, a unique DNA structure that forms in response to HBV infection in the nuclei of liver cells. Additionally, the HBV DNA can integrate into the human genome becoming a source of hepatitis B surface antigen, or HBsAg. While currently available treatments can manage HBV replication, they do not clear cccDNA from the infected liver cells. This inability to prevent HBV infection rebound from cccDNA is a key challenge to curing HBV. In September 2022, we presented preclinical data that demonstrated the potential of our multiplex base editors to reduce viral markers, including HBsAg expression, and prevent viral rebound of HBV in in vivo models.

In vivo AAV

AAV is a clinically validated technology that has been extensively used for gene delivery to a variety of tissues. AAV is a small, non-pathogenic virus that can be repurposed to carry a therapeutic payload, making it a suitable vector for delivery of gene editing therapies. Several clinical trials have been conducted or are in progress with different AAV variants for multiple diseases, including diseases of the eye, liver, muscle, lung and central nervous system. We have an option to in-license a variety of AAV variants that could be selected for optimal distribution to multiple organs. Because our DNA base editors are larger than the approximate 4.5kb packaging limit of AAV vectors, we use a novel split intein technology that is designed to deliver the base editor and guide RNA by co-infection with two viruses, where each virus contains approximately one half of the editor.

Ocular disorders: Stargardt disease

We are currently evaluating AAV technology to correct one of the most prevalent mutations in the ABCA4 gene causing Stargardt disease, a progressive macular degeneration disease. This mutation is known as the G1961E point mutation and approximately 5,500 individuals in the United States are affected.

Disease modeling using tiny light stimuli through holes that are equivalent in size to a single photoreceptor cell, suggests that only 12%-20% of these cells are necessary to preserve vision. We anticipate, therefore, that editing percentages in the range of 12%-20% of these cells would be disease-modifying, since each edited cell will be fully corrected and protected from the biochemical defect associated with Stargardt disease.

In a human retinal pigment epithelial cell line (ARPE-19 cells) in which we have knocked in the ABCA4 G1961E point mutation, we have demonstrated the precise correction of approximately 75% of the disease alleles at five weeks after dual infection with the split AAV system. In November 2021, we announced that we have initiated preclinical studies in NHPs for our Stargardt program.

Delivery of genetic medicines

To complement our next-generation gene editing technologies, we are also making significant investments in a broad suite of delivery technologies designed to deliver gene editing or other nucleic acid payloads to the right cells and enable potentially curative therapy. These delivery technologies include ex vivo electroporation, nonviral vectors such as LNPs, and viral vectors such as AAVs. In our pipeline, we have initially focused on applications of these technologies where their delivery capabilities have already been clinically-validated by third parties, such as ex vivo editing of blood stem cells and LNP delivery to the liver. Longer term, we are also investing in more innovative delivery options, such as LNPs that could target other organs beyond the liver, or novel viral vectors beyond AAV. We have also developed critical enabling capabilities such as mRNA manufacturing and cell processing for autologous and allogeneic cell therapy.

Consistent with this approach, our acquisition of Guide Therapeutics, Inc., or Guide, expanded our ability to explore new tissues and disease indications with our editing technologies. With Guide’s proprietary screening technology, which utilizes DNA barcodes to enable high throughput in vivo LNP screening, we have a broad library of lipids and lipid formulations, and we have generated additional novel LNPs that we believe can accelerate novel nonviral delivery of gene editing or other nucleic acid payloads to tissues beyond the liver. For example, we have used our DNA barcoding technology to identify a family of LNPs for delivery of base editors to HSPCs in mice, and we have screened more than 1,000 LNPs to identify LNPs that achieve durable, dose-dependent mRNA transfection in HSPCs in mice and NHPs in preclinical studies.

Manufacturing of genetic medicines

To realize the full potential of base editors as a differentiated class of medicines and to enable our parallel investment strategy in multiple delivery modalities, we are building customized and integrated capabilities across discovery, manufacturing, and preclinical and clinical development. Due to the critical importance of high-quality manufacturing and control of production timing and know-how, we have taken steps toward establishing our own manufacturing facility, which will provide us the flexibility to manufacture a variety of different product modalities. We believe this investment will maximize the value of our portfolio and capabilities, the probability of technical success of our programs, and the speed at which we can provide potentially life-long cures to patients.

In August 2020, we entered into a lease agreement with Alexandria Real Estate Equities, Inc. to build a 100,000 square foot current cGMP compliant manufacturing facility in Research Triangle Park, North Carolina intended to support a broad range of clinical programs. The initial estimate of the minimum amount of undiscounted lease payments due under this lease is $69.0 million. The tabular disclosure of minimum lease payments above under Note 7, Leases, includes payments due under this lease beginning in 2023. We anticipate that the facility will be operational in the first quarter of 2023. The project is facilitated, in part, by a Job Development Investment Grant approved by the North Carolina Economic Investment Committee, which authorizes potential reimbursements based on new tax revenues generated through the project. The facility is designed to support manufacturing for our ex vivo cell therapy programs in hematology and oncology and in vivo non-viral delivery programs for liver diseases, with flexibility to support manufacturing of our viral delivery programs, and ultimately, scale-up to support potential commercial supply.

For our initial waves of clinical trials, we expect to use CMOs with relevant manufacturing experience in genetic medicines.

Collaborations

We believe our collection of base editing, gene editing and delivery technologies has significant potential across a broad array of genetic diseases. To fully realize this potential, we have established and will continue to seek out innovative collaborations, licenses, and strategic alliances with pioneering companies and with leading academic and research institutions. Additionally, we have and will continue to pursue relationships that potentially allow us to accelerate our preclinical research and development efforts. These relationships will allow us to aggressively pursue our vision of maximizing the potential of base editing to provide life-long cures for patients suffering from serious diseases.

In vivo collaborations

Pfizer

In December 2021, we entered into a research collaboration agreement with Pfizer Inc., or Pfizer, focused on in vivo base editing programs for three targets for rare genetic diseases of the liver, muscle and central nervous system. The collaboration has an initial term of four years and may be extended for an additional one year on a program-by-program basis. Under the terms of the agreement, we will conduct all research activities through development candidate selection for three pre-specified, undisclosed targets, which are not included in our existing programs. Pfizer may opt in to exclusive, worldwide licenses to each development candidate, after which it will be responsible for all development activities, as well as potential regulatory approvals and commercialization, for each such development candidate. We have a right to opt in, at the end of Phase 1/2 clinical trials, upon the payment of an option exercise fee, to a global co-development and co-commercialization agreement with respect to one program licensed under the collaboration pursuant to which we and Pfizer would share net profits as well as development and commercialization costs in a 35%/65% ratio (Beam/Pfizer).

Apellis Pharmaceuticals

In June 2021, we entered into a research collaboration agreement with Apellis Pharmaceuticals, Inc., or Apellis, focused on the use of certain of our base editing technology to discover new treatments for complement system-driven diseases. Under the terms of the agreement, we 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 and will assume responsibility for subsequent development. We may elect to enter into a 50-50 U.S. co-development and co-commercialization agreement with Apellis with respect to one program licensed under the collaboration.

Verve Therapeutics

In April 2019, we entered into a collaboration and license agreement, or the Verve Agreement, with Verve Therapeutics, Inc., or Verve, a company focused on gene editing for cardiovascular disease treatments, and in July 2022, we and Verve amended the Verve Agreement. This collaboration allows us to more fully realize the potential of base editing in treating cardiovascular disease, a disease area outside of our core focus and where Verve has significant expertise. Under the terms of the Verve Agreement, as amended, we granted Verve exclusive worldwide licenses under certain of our editing technologies for human therapeutic applications against a total of three liver-mediated, cardiovascular disease targets, including use of our base editing technology for each of these targets and use of certain of our gene editing technology for two of such targets. In exchange, we received shares of Verve common stock. Additionally, we are eligible to receive milestone payments for certain clinical and regulatory events for licensed products, and we retain the option, after the final dosing of the final patient in a Phase 1 clinical trial of a licensed product, to participate in future development and commercialization, and share 35% of worldwide profits and losses, for any licensed product directed against one of these targets, and share 50% of U.S. profits and losses, for any licensed product directed against the other two targets.

In January 2021, Verve announced it had selected VERVE-101 as its lead product to be developed initially for the treatment of heterozygous familial hypercholesterolemia, or HeFH, a potentially fatal genetic heart disease. Individuals with HeFH have a genetic mutation causing high LDL-C levels in the blood. Over time, high LDL-C builds up in the heart’s arteries, resulting in reduced blood flow or blockage, and ultimately heart attack or stroke. Inactivation of the proprotein convertase subtilisin/kexin type 9, or PCSK9, gene has been shown to up-regulate LDL receptor expression, which leads to lower LDL-C levels. By making a single A-to-G change in the DNA genetic sequence of PCSK9, VERVE-101 aims to inactivate the target gene. In January 2021, Verve also reported preclinical proof-of-concept data in NHPs that demonstrated the successful use of ABEs to turn off PCSK9.

In July 2022, Verve announced that the first patient had been dosed with VERVE-101 in New Zealand as part of its global Phase 1b clinical trial evaluating VERVE-101 as a treatment for patients with HeFH. Verve also announced, in July 2022, that it anticipates obtaining regulatory clearance for an IND application in the United States in the second half of 2022, and it announced, in September 2022, that it has obtained regulatory clearance for a clinical trial application in the United Kingdom.

Institute of Molecular and Clinical Ophthalmology Basel

In July 2020, we announced a research collaboration with the Institute of Molecular and Clinical Ophthalmology Basel, or IOB. Founded in 2018 by a consortium that includes Novartis, the University Hospital of Basel and the University of Basel, IOB is a leader in basic and translational research aimed at treating impaired vision and blindness. Clinical scientists at IOB have also helped to develop better ways to measure how vision is impacted by Stargardt disease.

Additionally, researchers at IOB have developed living models of the retina, known as organoids, which can be used to test novel therapies. Under the terms of the agreement with IOB, the parties will leverage IOB’s unique expertise in the field of ophthalmology along with our novel base editing technology to advance programs directed to the treatment of certain ocular diseases, including Stargardt disease.

Ex vivo collaborations

Sana Biotechnology

In October 2021, we entered into an option and license agreement, or the Sana Agreement, with Sana Biotechnology, Inc., or Sana, pursuant to which we granted Sana non-exclusive research and development and commercial rights to our CRISPR Cas12b technology to perform nuclease editing for certain ex vivo engineered cell therapy programs. Under the terms of the Sana Agreement, licensed products include certain specified allogeneic T cell and stem cell-derived products directed at specified genetic targets, with certain limited rights for Sana to add and substitute such products and targets. The Sana Agreement excludes the grant of any Beam-controlled rights to perform base editing.

Boston Children’s Hospital

In July 2020, we entered into an alliance agreement, or the BCH Agreement, with Boston Children’s Hospital, or Boston Children’s. Under the terms of the BCH Agreement, we will identify and sponsor research programs to be performed at Boston Children’s, either solely by Boston Children’s or by both Boston Children’s and us, to facilitate the development of certain disease-specific therapies using our proprietary base editing technology. Boston Children’s will also serve as a clinical site to advance bench-to-bedside translation of our pipeline across certain therapeutic areas of interest, including programs in sickle cell disease and pediatric leukemias and exploration of new programs targeting other diseases.

Magenta Therapeutics

In June 2020, we announced a non-exclusive research and clinical trial collaboration agreement with Magenta Therapeutics Inc., or Magenta, to evaluate the potential utility of MGTA-117, Magenta’s novel targeted antibody-drug conjugate, for conditioning of patients with sickle cell disease and beta-thalassemia receiving our base editing therapies. Conditioning is a critical component necessary to prepare a patient’s body to receive the edited cells, which carry the corrected gene and must engraft in the patient’s bone marrow in order to be effective. Today’s conditioning regimens rely on nonspecific chemotherapy or radiation, which are associated with significant toxicities. MGTA-117 is designed to precisely target only hematopoietic stem and progenitor cells, to spare immune cells, and has shown high selectivity, potent efficacy, wide safety margins and broad tolerability in NHP models. MGTA-117 may be capable of clearing space in bone marrow to support long-term engraftment and rapid recovery in patients. Combining the precision of our base editing technology with the more targeted conditioning regimen enabled by MGTA-117 has the potential to further improve therapeutic outcomes for patients suffering from these severe diseases.

Other Collaborations

Orbital Therapeutics

In September 2022, we entered into a license and research collaboration agreement, or the Orbital Agreement, with Orbital Therapeutics, Inc., or Orbital, pursuant to which each of us granted the other licenses to certain technology controlled during the three years after entry into the Orbital Agreement that are necessary or reasonably useful for the non-viral delivery or the design or manufacture of ribonucleic acid for the prevention, treatment or diagnosis of human disease. Our license to Orbital is for all fields other than our exclusive field and also excludes the targets and substantially all of the indications that are the subject of our existing programs. Our exclusive field consists of all products and biologics that function in the process of gene editing or conditioning for use in cell transplantation, or that act in combination with any such products or biologics. Orbital’s license to us is for all fields other than Orbital’s exclusive field. Orbital’s exclusive field consists of products and biologics that function as vaccines and also of therapeutic proteins, other than therapeutic proteins (i) that use gene editing, (ii) for use in conditioning, (iii) for use in regenerative medicine, (iv) for use as a chimeric antigen receptor, or CR, immune therapy, including CAR-T, CAR-NK and CAR-macrophage compositions, (v) for use as a t-cell receptor therapy or (vi) that modulate certain immune responses. The licenses are exclusive in each party’s exclusive field for three years and non-exclusive in those fields thereafter. We and Orbital agreed that for a period of three years after entry into the Orbital Agreement, subject to limited exceptions, we would not research, develop and commercialize, or grant licenses to research, develop and commercialize, products or biologics within the other party’s exclusive field.

Acquisitions

In February 2021, we acquired Guide Therapeutics, Inc., or Guide, for upfront consideration in an aggregate amount of $120.0 million, excluding customary purchase price adjustments, in shares of our common stock, based upon the volume-weighted average price of the common stock over the ten trading-day period ending on February 19, 2021. 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 our common stock.

COVID-19

With the ongoing concern related to the COVID-19 pandemic, we maintained our business continuity plans to address and mitigate the impact of the COVID-19 pandemic on our business. We expect to continue incurring additional costs to ensure we adhere to the guidelines instituted by the Centers for Disease Control and to provide a safe working environment to our onsite employees.

The extent to which the COVID-19 pandemic impacts our business, our corporate development objectives, results of operations and financial condition, including the value of and market for our common stock, will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the duration, scope and severity of the pandemic, the existence and duration of any travel restrictions or business restrictions in the United States and other countries, business closures and business disruptions, the effectiveness of actions taken in the United States and other countries to contain and treat the disease, periodic spikes in infection rates, new strains of the virus that cause outbreaks of COVID-19, and the broad availability of effective vaccines and therapeutics.

Disruptions to the global economy and supply chain, disruption of global healthcare systems, and other significant impacts of the COVID-19 pandemic could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

While the COVID-19 pandemic did not significantly impact our business or results of operations during the three or nine months ended September 30, 2022, the length and extent of the pandemic, its consequences, and containment efforts will determine its future impact on our operations and financial condition.

Critical accounting policies and significant judgements and estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance with U.S. generally accepted accounting principles. The preparation of our financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies are those policies which require the most significant judgments and estimates in the preparation of our condensed consolidated financial statements. We have determined that our most critical accounting policies are those relating to stock-based compensation, variable interest entities, fair value measurements, and leases. There have been no significant changes to our existing critical accounting policies and significant judgements and estimates discussed in the 2021 Form 10-K.

Financial operations overview

General

We were founded in January 2017 and began operations in July 2017. Since our inception, we have devoted substantially all of our resources to building our base editing platform and advancing development of our portfolio of programs, establishing and protecting our intellectual property, conducting research and development activities, organizing and staffing our company, business planning, raising capital and providing general and administrative support for these operations. To date, we have financed our operations primarily through the sales of our redeemable convertible preferred stock, proceeds from offerings of our common stock and payments received under collaboration and license agreements.

We are an early-stage company, and all of our programs are at a preclinical or early clinical stage of development. To date, we have not generated any revenue from product sales and do not expect to generate revenue from the sale of products for the foreseeable future. Our revenue to date has been primarily derived from license and collaboration agreements with partners. Since inception we have incurred significant operating losses. Our net losses for the nine months ended September 30, 2022 and 2021 were $250.7 million and $305.9 million, respectively. As of September 30, 2022, we had an accumulated deficit of $1.0 billion. We expect to continue to incur significant expenses and increasing operating losses in connection with ongoing development activities related to our internal programs and collaborations as we continue our preclinical and clinical development of product candidates; advance additional product candidates toward clinical development; build and operate our cGMP facility in North Carolina; further develop our base editing platform; continue to make investments in delivery technology for our base editors, including the LNP technology we acquired through our acquisition of Guide; conduct research activities as we seek to discover and develop additional product candidates; maintain, expand, enforce, defend and protect our intellectual property portfolio; and continue to hire research and development, clinical, technical operations and commercial personnel. In addition, we expect to continue to incur the costs associated with operating as a public company.

As a result of these anticipated expenditures, we will need to raise additional capital to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances, and licensing arrangements. We may be unable to raise additional funds or enter into such other agreements when needed on favorable terms or at all. Our inability to raise capital as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy. We can give no assurance that we will be able to secure such additional sources of capital to support our operations, or, if such capital is available to us, that such additional capital will be sufficient to meet our needs for the short or long term.

Revenue Recognition

In April 2019, we entered into a collaboration and license agreement, or the Verve Agreement, with Verve Therapeutics, Inc., or Verve, a company focused on gene editing for cardiovascular disease treatments. In June 2021, we entered into a research collaboration agreement, or the Apellis Agreement, with Apellis Pharmaceuticals, Inc., or Apellis, focused on the use of certain of our base editing technology to discover new treatments for complement system-driven diseases. In October 2021, we entered into an option and license agreement, or the Sana Agreement, with Sana Biotechnology, Inc., or Sana, pursuant to which we granted Sana non-exclusive research and development and commercial rights to our CRISPR Cas12b technology to perform nuclease editing for certain ex vivo engineered cell therapy programs. In December 2021, we entered into a research collaboration agreement, or the Pfizer Agreement, with Pfizer Inc., or Pfizer, focused on in vivo base editing programs for three targets for rare genetic diseases of the liver, muscle and central nervous system. In September 2022, we entered into the Orbital Agreement, with Orbital, pursuant to which each of us granted the other licenses to certain technology controlled during the three years after entry into the Orbital Agreement that are necessary or reasonably useful for the non-viral delivery or the design or manufacture of ribonucleic acid for the prevention, treatment or diagnosis of human disease.

We have not generated any revenue to date from product sales and do not expect to do so in the near future. During the nine months ended September 30, 2022 and 2021, we recognized $40.9 million and $0.8 million of license and collaboration revenue, respectively.

Research and development expenses

Research and development expenses consist of costs incurred in performing research and development activities, which include:

•

Expenses incurred in connection with investments in delivery technology for our base editors, including the LNP technology we acquired through our acquisition of Guide;

•

the cost to obtain licenses to intellectual property, such as those with Harvard University, or Harvard, The Broad Institute, Inc., or Broad Institute, Editas Medicine, Inc, or Editas, and Bio Palette Co., Ltd., or Bio Palette, and related future payments should certain success, development and regulatory milestones be achieved;

•

personnel-related expenses, including salaries, bonuses, benefits and stock-based compensation for employees engaged in research and development functions;

•

expenses incurred in connection with the discovery and preclinical development of our research programs, including under agreements with third parties, such as consultants, contractors and contract research organizations;

In the early phases of development, our research and development costs are often devoted to product platform and proof-of-concept preclinical studies that are not necessarily allocable to a specific target.

We expect that our research and development expenses will increase substantially as we advance our programs through their planned preclinical and clinical development.

General and administrative expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our executive, intellectual property, business development and administrative functions. General and administrative expenses also include legal fees relating to intellectual property and corporate matters, professional fees for accounting, auditing, tax and consulting services, insurance costs, travel, and direct and allocated facility related expenses and other operating costs.

We anticipate that our general and administrative expenses will increase in the future to support our increased research and development activities. We also expect to continue to incur costs associated with being a public company and maintaining controls over financial reporting, including costs of accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with Nasdaq and SEC requirements, director and officer insurance costs, and investor and public relations costs.

Other income and expenses

Other income and expenses consist of the following items:

•

Change in fair value of derivative liabilities consists primarily of remeasurement gains or losses associated with changes in success payment liabilities associated with our license agreement with Harvard, dated as of June 27, 2017, as amended, or the Harvard License Agreement, and the license agreement with The Broad Institute, as amended, dated as of May 9, 2018, or the Broad License Agreement.

License and collaboration revenue

License and collaboration revenue was $15.8 million and $0.8 million for the three months ended September 30, 2022 and 2021, respectively. License and collaboration revenue represents revenue recorded under the Pfizer, Apellis, and Verve Agreements.

Research and development expenses

Research and development expenses were $85.3 million and $54.6 million for the three months ended September 30, 2022 and 2021, respectively. The increase of $30.7 million was primarily due to the following:

•

An increase of $12.4 million in personnel-related costs and $3.4 million in facility-related costs, including depreciation and costs associated with moving into our newly constructed office and laboratory space during the second half of 2021. These increases were due to the growth in the number of research and development employees from 250 at September 30, 2021 to 420 at September 30, 2022, and their related activities, as well as the expense allocated to research and development related to our leased facilities.

•

An increase of $6.3 million in stock-based compensation from additional equity awards due to the increase in the number of research and development employees and the issuance of annual equity awards to existing employees;

•

An increase of $4.2 million in lab supplies due to the movement of our lead programs into IND-enabling activities and continued investment in platform and discovery efforts;

•

An increase of $5.2 million in outsourced services, driven by animal studies primarily to further our LNP platform, assay development and qualification activities for BEAM-102 and BEAM-201 to support IND enabling studies and clinical start up activities for BEAM-101;

•

An increase of $1.9 million in other expenses, primarily related to an increase in overall IT spend related to the growth of the organization and increase in research and development specific software costs.; and

•

A decrease of $2.8 million in license expenses due primarily to decreases in non-royalty sublicense fees owed to Harvard related to the Apellis Agreement as well as milestones owed upon filing of our IND for BEAM-101 during 2021.

Research and development expenses are expected to continue to increase as we initiate clinical trials for BEAM-101, continue IND-enabling studies for BEAM-201, begin IND-enabling studies for BEAM-301, continue our current research programs, initiate new research programs, continue the preclinical and clinical development of our product candidates and conduct any future preclinical studies and begin to enroll patients in and conduct clinical trials for any of our product candidates.

General and administrative expenses

General and administrative expenses were $21.8 million and $15.8 million for the three months ended September 30, 2022 and 2021, respectively. The increase of $6.0 million was primarily due to the following:

•

An increase of $2.9 million in stock-based compensation from additional equity awards due to the growth in the number of general and administrative employees from 56 employees as of September 30, 2021 to 87 employees as of September 30, 2022, and the issuance of annual equity awards to existing employees;

•

An increase of $2.8 million in personnel related costs due to an increase in general and administrative employees; and

•

An increase of $0.3 million in legal costs primarily due to legal fees incurred in connection with business development activities.

Change in fair value of derivative liabilities

During the three months ended September 30, 2022, we recorded $4.9 million of expense related to the change in fair value of success payment liabilities due to an increase in the price of our common stock over the same period. During the three months ended September 30, 2021, we recorded $35.8 million of other income due to a decrease in the price of our common stock over the same period. A portion of the success payment obligations were paid in June 2021; the remaining success payment obligations are still outstanding as of September 30, 2022 and will continue to be revalued at each reporting period.

Change in fair value of non-controlling equity investments

During the three months ended September 30, 2022 and 2021, we recorded $10.4 million of other income and $4.9 million of other expense, respectively, as a result of changes in the fair value of our investment in Verve’s common stock.

Change in fair value of contingent consideration liabilities

During the three months ended September 30, 2022 and 2021, we recorded $0.9 million of other expense and $10.6 million of other income, respectively, related to the change in fair value of the Guide technology and product contingent consideration liabilities. These changes are a result of an update in project timelines and the expected probability of achievement of the milestones.

Interest and other income (expense), net

Interest and other income (expense), net was $5.0 million of net income for the three months ended September 30, 2022 as compared to $9.0 thousand of net income for the three months ended September 30, 2021. The change was primarily due to increases in interest income driven by increased market rates and growth of our portfolio.

Provision for income taxes

We recorded an income tax provision of $2.4 million for the three months ended September 30, 2022. The provision is primarily attributable to the recognition of revenue for tax purposes under the collaboration agreements with Apellis and Pfizer, which were deferred in 2021 for tax purposes as well as the requirement under the Tax Cuts and Jobs Act of 2017 for taxpayers to capitalize and amortize research and development expenditures over five or fifteen years.

Loss from equity method investment

We record our share of gains or losses from Orbital on a quarterly basis. For the three months ended September 30, 2022, we recorded a loss from equity method investment of $25.5 million in association with a basis difference attributable to Orbital's in-process research and development with no alternative future use, which was immediately expensed as of the date of this investment. As of September 30, 2022, the investment has been written down to zero. See Notes 2 and 8 to our condensed consolidated financial statements for more information regarding the equity method of accounting.

License and collaboration revenue

License and collaboration revenue was $40.9 million and $0.8 million for the nine months ended September 30, 2022 and 2021, respectively. License and collaboration revenue represents revenue recorded under the Pfizer, Apellis, and Verve Agreements.

Research and development expenses

Research and development expenses were $225.3 million and $290.3 million for the nine months ended September 30, 2022 and 2021, respectively. The decrease of $65.1 million was primarily due to the following:

•

A decrease of $155.0 million related to the write-off of in-process research and development asset acquired from Guide during the nine months ended September 30, 2021 as it was determined to be of no alternative future use;

•

An increase of $35.6 million in personnel-related costs and $8.8 million in facility-related costs, including depreciation. These increases were due to the growth in the number of research and development employees from 250 at September 30, 2021 to 420 at September 30, 2022 and their related activities, as well as the expense allocated to research and development related to our leased facilities;

•

An increase of $21.5 million in stock-based compensation from additional stock option awards due to the increase in the number of research and development employees and the issuance of annual equity awards to existing employees;

•

An increase of $11.5 million in lab supplies due to growth in the number of research and development employees, movement of BEAM-102 into IND enabling activities, internal mRNA production costs to support our liver portfolio as well as continued investment in platform and discovery efforts.

•

An increase of $5.3 million in other expenses, primarily related to an increase in overall IT spend driven by growth of the organization as well as increase in research and development specific software costs.

•

An increase of $8.4 million in outsourced services, driven by process development and assay development and qualification activities to support BEAM-102 and BEAM-301 programs, clinical start-up activities and clinical assays for BEAM-101, and animal studies to further advancement of our liver portfolio; partially offset by lower manufacturing costs related to BEAM-201 gRNA and lentivirus in 2021; and

•

A decrease of $1.2 million in license expenses due to BEAM-101 IND milestone costs incurred during September 2021 and manufacturing specific license expense incurred in 2021.

General and administrative expenses

General and administrative expenses were $65.1 million and $39.5 million for the nine months ended September 30, 2022 and 2021, respectively. The increase of $25.7 million was primarily due to the following:

•

An increase of $12.2 million in stock-based compensation due from additional equity awards due to the increase in the number of general and administrative employees from 56 employees as of September 30, 2021 to 87 employees as of September 30, 2022 and the issuance of annual equity awards to existing employees;

•

An increase of $8.8 million in personnel related costs due to an increase in general and administrative employees;

•

An increase of $4.7 million in legal costs primarily due to $3.4 million accrual in connection with a dispute with a research institution and legal fees incurred in connection with business development activities; see Note 6 to our condensed consolidated financial statements for more information regarding the dispute;

•

An increase of $0.4 million in insurance costs due to higher premiums attributable to the Company's directors and officers insurance policy; and

•

A decrease of $0.5 million of other expenses primarily due to a decrease in information technology costs allocated to general and administrative functions.

Change in fair value of derivative liabilities

During the nine months ended September 30, 2022, we recorded $20.9 million of other income related to the change in fair value of success payment liabilities due to a decrease in the price of our common stock over the same period. During the nine months ended September 30, 2021, we recorded $8.4 million of other expense due to an increase in the price of our common stock over the same period. A portion of the success payment obligations were paid in June 2021; the remaining success payment obligations are still outstanding as of September 30, 2022 and will continue to be revalued at each reporting period.

Change in fair value of non-controlling equity investments

During the nine months ended September 30, 2022 and 2021, we recorded $1.4 million of other expense and $22.0 million of other income, respectively, as a result of changes in the fair value of our investment in Verve’s common stock.

Change in fair value of contingent consideration liabilities

During the nine months ended September 30, 2022 and 2021, we recorded $0.5 million of other expense and $9.6 million of other income, respectively, related to the change in fair value of the Guide technology and product contingent consideration liabilities. These changes are a result of an update in project timelines and the expected probability of achievement of the milestones.

Interest and other income (expense), net

Interest and other income (expense), net was $7.7 million of net income for the nine months ended September 30, 2022 as compared to $0.1 million of net expense for the nine months ended September 30, 2021. The increase was primarily due to increases in interest income driven by increased market rates and growth of our portfolio.

Provision for income taxes

We recorded an income tax provision of $2.4 million for the nine months ended September 30, 2022. The provision is primarily attributable to the recognition of revenue for tax purposes under the collaboration agreements with Apellis and Pfizer, which were deferred in 2021 for tax purposes as well as the requirement under the Tax Cuts and Jobs Act of 2017 for taxpayers to capitalize and amortize research and development expenditures over five or fifteen years.

Loss from equity method investment

We record our share of gains or losses from Orbital on a quarterly basis. For the nine months ended September 30, 2022, we recorded a loss from equity method investment of $25.5 million in association with a basis difference attributable to Orbital's in-process research and development with no alternative future use, which was immediately expensed as of the date of this investment. As of September 30, 2022, the investment has been written down to zero. See Notes 2 and 8 to our condensed consolidated financial statements for more information regarding the equity method of accounting.

Liquidity and capital resources

Since our inception in January 2017, we have not generated any revenue from product sales, have generated only limited license and collaboration revenue from our license and collaboration agreements, and have incurred significant operating losses and negative cash flows from our operations. We expect to incur significant expenses and operating losses for the foreseeable future as we advance the preclinical and the clinical development of our product candidates.

To date, we have funded our operations primarily through equity offerings. In January 2021, we issued and sold 2,795,700 shares of our common stock in a private placement at an offering price of $93.00 per share for aggregate gross proceeds of $260.0 million. We received $252.0 million in net proceeds after deducting offering expenses payable by us.

In April 2021, we filed a universal shelf registration statement on Form S-3 with the SEC, or the 2021 Shelf, to register for sale an indeterminate amount of our common stock, preferred stock, debt securities, warrants and/or units in one or more offerings, which became effective upon filing with the SEC (File No. 333-254946).

In April 2021, we entered into an at the market, or ATM, sales agreement, or the Sales Agreement, with Jefferies LLC, or Jefferies, pursuant to which we were entitled to offer and sell, from time to time at prevailing market prices, shares of our common stock having aggregate gross proceeds of up to $300.0 million. We 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. Between April and July 2021, we sold 2,908,009 shares of our 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 us.

In June 2021, we entered into the Apellis Agreement, which is focused on the use of certain of our base editing technology to discover new treatments for complement system-driven diseases. Pursuant to the Apellis Agreement, we received an upfront payment of $50.0 million in July 2021 and were eligible to receive an additional $25.0 million payment on the one-year anniversary of the effective date of the Apellis Agreement, or the First Anniversary Payment. In June 2022, we received the $25.0 million First Anniversary Payment.

In July 2021, we and Jefferies entered into an amendment to the Sales Agreement to provide for an increase in the aggregate offering amount under the Sales Agreement, such that as of July 7, 2021, we may offer and sell shares of common stock having an aggregate offering price of an additional $500.0 million. As of September 30, 2022, we have sold 3,248,633 additional shares of our common stock under the amended Sales Agreement at an average price of $89.06 per share for aggregate gross proceeds of $289.3 million, before deducting commissions and offering expenses payable by us.

In December 2021, we entered into the Pfizer Agreement, which is focused on in vivo base editing programs for three targets for rare genetic diseases of the liver, muscle and central nervous system. Under the terms of the Pfizer Agreement, we will conduct all research activities through development candidate selection for three undisclosed targets, which are not included in our existing programs. Pursuant to the Pfizer Agreement, we received an upfront payment of $300.0 million in January 2022.

As of September 30, 2022, we had $1.1 billion in cash, cash equivalents, and marketable securities.

We are required to make success payments to Harvard and Broad Institute based on increases in the per share fair market value of our Series A-1 Preferred Stock and Series A-2 Preferred Stock or, subsequent to our IPO, our common stock. The amounts due may be settled in cash or shares of our common stock, at our discretion. In May 2021, the first success payment measurements occurred and success payments to Harvard and Broad Institute were calculated to be $15.0 million and $15.0 million, respectively. We elected to make each payment in shares of our common stock and issued 174,825 shares to each of Harvard and Broad Institute to settle these liabilities in June 2021. We may additionally owe Harvard and Broad Institute success payments of up to an additional $90.0 million each.

We have not yet commercialized any of our product candidates, and we do not expect to generate revenue from the sale of our product candidates for the foreseeable future. We anticipate that we may need to raise additional capital in order to continue to fund our research and development, including our planned preclinical studies and clinical trials, building, maintaining and operating a commercial-scale cGMP manufacturing facility, and new product development, as well as to fund our general operations. As necessary, we will seek to raise additional capital through various potential sources, such as equity and debt financings or through corporate collaboration and license agreements. We can give no assurances that we will be able to secure such additional sources of capital to support our operations, or, if such funds are available to us, that such additional financing will be sufficient to meet our needs.

Cash flows

The following table summarizes our sources and uses of cash (in thousands):


	Nine Months Ended September 30,
	2022			2021
Net cash provided by (used in) operating activities	$	91,718		$	(68,098	)
Net cash used in investing activities		(574,775	)		(216,648	)
Net cash provided by financing activities		79,578			734,598
Net change in cash, cash equivalents and restricted cash	$	(403,479	)	$	449,852

Operating activities

Net cash provided by operating activities for the nine months ended September 30, 2022 was $91.7 million, consisting primarily of the collection of collaboration receivables of $300.0 million related to the Pfizer Agreement and an increase in operating lease liabilities totaling $13.5 million, as well as noncash items consisting of stock-based compensation expense of $61.8 million, a loss from an equity method investment of $25.5 million, depreciation and amortization expense of $10.2 million, changes in operating lease ROU assets of $6.2 million, a decrease in the fair value of a non-controlling equity investment of $1.4 million, and an increase in the fair value of contingent consideration liabilities of $0.5 million. These sources of cash were partially offset by our net loss of $250.7 million, decreases in accrued expenses and other liabilities of $25.4 million, a decrease in deferred revenue of $15.9 million, net of the $25.0 million First Anniversary Payment collected from Apellis during the nine months ended September 30, 2022, an increase in prepaid expenses and other current assets of $7.2 million, decreases in other long-term liabilities of $2.5 million and accounts payable of $0.5 million, and noncash items including decreases in the fair value of derivative liabilities of $20.9 million, as well as amortization of investment premiums of $4.3 million.

Net cash used in operating activities for the nine months ended September 30, 2021 was $68.1 million, consisting primarily of our net loss of $305.9 million, a decrease in accounts payable of $1.3 million and noncash items including an increase in the fair value of a non-controlling equity investment of $22.0 million and a change in fair value of contingent consideration liabilities of $9.6 million. These uses of cash were offset in part by an increase in deferred revenue of $49.2 million, primarily related to the Apellis Agreement, an increase in operating lease liabilities of $15.2 million, an increase in accrued expenses and other liabilities of $2.8 million, and a decrease in prepaid expenses and other current assets of $0.7 million and noncash items consisting primarily of in-process research and development expenses of $155.0 million, stock-based compensation expense of $28.1 million, change in fair value of derivative liabilities of $8.4 million, a change in operating lease ROU assets of $6.8 million and depreciation and amortization expense of $4.8 million.

Investing activities

For the nine months ended September 30, 2022, cash used in investing activities was primarily the net purchases of marketable securities of $534.1 million, and purchases of property and equipment of $40.7 million.

For the nine months ended September 30, 2021, cash used in investing activities was primarily the net purchases of marketable securities of $183.8 million, and purchases of property and equipment of $33.4 million. We also received $0.6 million in net cash from our acquisition of Guide, after the payment of acquisition costs.

Financing activities

Net cash provided by financing activities for the nine months ended September 30, 2022 consisted primarily of proceeds from equity offerings of $76.4 million, $3.1 million of proceeds from the issuance of common stock under our Employee Stock Purchase Plan, and $2.0 million of proceeds from the exercise of stock options, offset in part by repayments of equipment financing liabilities of $1.7 million and equity offering costs of $0.1 million.

Net cash provided by financing activities for the nine months ended September 30, 2021 consisted primarily of proceeds from equity offerings of $737.2 million and proceeds from the exercise of stock options of $7.7 million, offset in part by the payment of equity offering costs of $8.7 million and repayments of equipment financing liabilities of $1.6 million.

Funding requirements

Our operating expenses are expected to increase substantially as we continue to advance our portfolio of programs.

Specifically, our expenses will increase if and as we:

•

initiate clinical trials of our product candidates, including our BEACON trial;

•

continue our research programs and our preclinical development of product candidates from our research programs;

•

seek to identify additional research programs and additional product candidates;

•

initiate preclinical studies and clinical trials for additional product candidates we identify and develop;

•

maintain, expand, enforce, defend, and protect our intellectual property portfolio and provide reimbursement of third-party expenses related to our patent portfolio;

•

seek marketing approvals for any of our product candidates that successfully complete clinical trials;

•

establish a sales, marketing, and distribution infrastructure to commercialize any medicines for which we may obtain marketing approval;

•

further develop our base editing platform;

•

further develop delivery technology for our base editors, including the LNP technology we acquired through our acquisition of Guide;

•

continue to hire additional personnel including research and development, clinical and commercial personnel;

•

add operational, financial, and management information systems and personnel, including personnel to support our product development;

•

acquire or in-license products, intellectual property, medicines and technologies; and

•

build, maintain, and operate a commercial-scale cGMP manufacturing facility.

We expect that our cash, cash equivalents and marketable securities at September 30, 2022 will enable us to fund our current and planned operating expenses and capital expenditures for at least the next 12 months from the date of issuance of our accompanying condensed consolidated financial statements. We have based these estimates on assumptions that may prove to be imprecise, and we may exhaust our available capital resources sooner that we currently expect. Because of the numerous risks and uncertainties associated with the development our programs, we are unable to estimate the amounts of increased capital outlays and operating expenses associated with completing the research and development of our product candidates.

Our future funding requirements will depend on many factors including:

•

the cost of continuing to build our base editing platform;

•

the costs of acquiring licenses for the delivery modalities that will be used with our product candidates;

•

the scope, progress, results, and costs of discovery, preclinical development, laboratory testing, manufacturing and clinical trials for the product candidates we may develop;

•

the costs of preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual property and proprietary rights, and defending intellectual property-related claims;

•

the costs, timing, and outcome of regulatory review of the product candidates we develop;

•

the costs of future activities, including product sales, medical affairs, marketing, manufacturing, distribution, coverage and reimbursement for any product candidates for which we receive regulatory approval;

•

the success of our license agreements and our collaborations;

•

our ability to establish and maintain additional collaborations on favorable terms, if at all;

•

the achievement of milestones or occurrence of other developments that trigger payments under any collaboration agreements we are a party to or may become a party to;

•

the payment of success liabilities to Harvard and Broad Institute pursuant to the respective terms of the Harvard License Agreement and the Broad Institute License Agreement, should we choose to pay in cash;

•

the extent to which we acquire or in-license products, intellectual property, and technologies;

•

the costs of obtaining, building, operating and expanding our manufacturing capacity; and

•

the impacts of the COVID-19 pandemic and our response to it.

A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Further, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, and licensing arrangements. We do not have any committed external source of capital. We have historically relied on equity issuances to fund our capital needs and will likely rely on equity issuances in the future. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends.

If we raise capital through additional collaborations, strategic alliances, or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, or product candidates, or we may have to grant licenses on terms that may not be favorable to us. If we are unable to raise additional capital through equity or debt financings when needed, we may be required to delay, limit, reduce, or terminate our product development or, if approved, future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. We can give no assurance that we will be able to secure such additional sources of funds to support our operations, or, if such funds are available to us, that such additional funding will be sufficient to meet our needs.

Contractual obligations

We enter into contracts in the normal course of business with contract research organizations and other vendors to assist in the performance of our research and development activities and other services and products for operating purposes. These contracts generally provide for termination on notice, and therefore are cancelable contracts and not included in our calculations of contractual obligations and commitments. We lease certain assets under noncancelable operating and finance leases, which expire through 2038. The leases relate primarily to office space and laboratory space in addition to equipment. Aggregate future minimum commitments under these office and laboratory leases and equipment leases are $265.2 million and $3.2 million, respectively, as of September 30, 2022, excluding any related common area maintenance charges or real estate taxes. During June 2022, our lease agreement with Alexandria Real Estate Equities, Inc. for the 100,000 square foot manufacturing facility in Research Triangle Park, North Carolina that has been built over the course of 2020 to 2022 commenced. The initial estimate of minimum amount of undiscounted lease payments due under this lease is $69.0 million, which is expected to be paid over a lease term of 15 years beginning in the first quarter of 2023. These payments are included in the tabular disclosure of minimum lease payments in Note 7, Leases. During the nine months ended September 30, 2022, there were no other material changes to our contractual obligations and commitments described under Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2021 Form 10-K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. As of September 30, 2022, we had cash, cash equivalents, and marketable securities of $1.1 billion, which consisted of cash, money market funds, commercial paper, corporate notes and a corporate equity security. Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because our investments are in short-term marketable securities. Due to the short-term duration of our investment portfolio and the low risk profile of our investments, we believe an immediate 10% change in interest rates would not have a material effect on the fair market value of our investment portfolio. We have the ability to hold our investments until maturity, and therefore, we would not expect our operating results or cash flows to be affected to any significant degree by the effect of a change in market interest rates on our investment portfolio.

We are not currently exposed to significant market risk related to changes in foreign currency exchange rates; however, we do contract with vendors that are located outside of the United States and may be subject to fluctuations in foreign currency rates. We may enter into additional contracts with vendors located outside of the United States in the future, which may increase our foreign currency exchange risk.

Inflation generally affects us by increasing our cost of labor and research, manufacturing and development costs. We believe that inflation has not had a material effect on our financial statements included elsewhere in this Quarterly Report on Form 10-Q. However, our operations may be adversely affected by inflation in the future.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on the evaluation of our disclosure controls and procedures as of September 30, 2022, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such date are effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

We continuously seek to improve the efficiency and effectiveness of our internal controls. This results in refinements to processes throughout our company. There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended September 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently subject to any material legal proceedings.

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. For a detailed discussion of the risks that affect our business. Please refer to the sections titled “Risk Factors Summary” and “Item 1A. Risk Factors” in the 2021 Form 10-K. The COVID-19 pandemic may also have the effect of heightening many of the other risks described in the section titled “Item 1A. Risk Factors” in each of the 2021 Form 10-K and our quarterly reports, such as risks related to our need to raise additional funding, fluctuation of our quarterly financial results, and our ability to obtain regulatory approvals for our product candidates.

The risk factors set forth below represent new risk factors or those containing changes to the similarly titled risk factor included in “Item 1.A Risk Factors” of the 2021 Form 10-K.

Our owned patents and patent applications and in-licensed patents and patent applications and other intellectual property may be subject to priority disputes or to inventorship disputes and similar proceedings. If we or our licensors are unsuccessful in any of these proceedings, we may be required to obtain licenses from third parties, which may not be available on commercially reasonable terms or at all, or to cease the development, manufacture, and commercialization of one or more of the product candidates we may develop, which could have a material adverse impact on our business.

Although we have an option to exclusively license certain patents and patent applications directed to Cas9 and Cas12a from Editas, who in turn has licensed such patents from various academic institutions including Broad Institute, we do not currently have a license to such patents and patent applications. Certain of the U.S. patents and one U.S. patent application to which we hold an option are co-owned by Broad Institute and MIT, and in some cases co-owned by Broad Institute, Massachusetts Institute of Technology, or MIT, and Harvard, which we refer to together as the Boston Licensing Parties, and were involved in U.S. interference No. 106,048 with one U.S. patent application co-owned by the University of California, the University of Vienna, and Emmanuelle Charpentier, which we refer to together as the University of California. On September 10, 2018, the Court of Appeals for the Federal Circuit, or the CAFC, affirmed the Patent Trial and Appeal Board of the USPTO’s, or PTAB’s, holding that there was no interference-in-fact. An interference is a proceeding within the USPTO to determine priority of invention of the subject matter of patent claims filed by different parties.

On June 24, 2019, the PTAB declared an interference (U.S. Interference No. 106,115) between ten U.S. patent applications ((U.S. Serial Nos. 15/947,680; 15/947,700; 15/947,718; 15/981,807; 15/981,808; 15/981,809; 16/136,159; 16/136,165; 16/136,168; and 16/136,175) that are co-owned by the University of California, and 13 U.S. patents and one U.S. patent application (U.S. Patent Nos. 8,697,359; 8,771,945; 8,795,965; 8,865,406; 8,871,445; 8,889,356; 8,895,308; 8,906,616; 8,932,814; 8,945,839; 8,993,233; 8,999,641; and 9,840,713, and U.S. Serial No. 14/704,551)) that are co-owned by the Boston Licensing Parties, which we have an option to under the Editas License Agreement. In the declared interference, the University of California has been designated as the junior party and the Boston Licensing Parties have been designated as the senior party.

As a result of the declaration of interference, an adversarial proceeding in the USPTO before the PTAB has been initiated, which is declared to ultimately determine priority, specifically and which party was first to invent the claimed subject matter. An interference is typically divided into two phases. The first phase is referred to as the motions or preliminary motions phase while the second is referred to as the priority phase. In the first phase, each party may raise issues including but not limited to those relating to the patentability of a party’s claims based on prior art, written description, and enablement. A party also may seek an earlier priority benefit or may challenge whether the declaration of interference was proper in the first place. Priority, or a determination of who first invented the commonly claimed invention, is determined in the second phase of an interference.

The ten University of California patent applications and the 13 U.S. patents and one U.S. patent application co-owned by the Boston Licensing Parties involved in U.S. Interference No. 106,115 generally relate to CRISPR/Cas9 systems or eukaryotic cells comprising CRISPR/Cas9 systems having fused or covalently linked RNA and the use thereof in eukaryotic cells. On February 28, 2022, the PTAB issued a decision that the Boston Licensing Parties have priority of invention over University of California with respect to a single RNA CRISPR-Cas9 system that functions in eukaryotic cells. This decision is being appealed.

There can be no assurance that the U.S. interference will be resolved in favor of the Boston Licensing Parties on appeal. If the U.S. interference resolves in favor of University of California, or if the Boston Licensing Parties’ patents and patent application are narrowed, invalidated, or held unenforceable, we may lose the ability to license the optioned patents and patent application and our ability to commercialize our product candidates may be adversely affected if we cannot obtain a license to relevant third party patents that cover our product candidates. We may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be nonexclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, we may be unable to commercialize our base editing platform technology or product candidates or such commercialization efforts may be significantly delayed, which could in turn significantly harm our business.

We or our licensors may be subject to similar interferences in the future with the same risks as described above. For example, on December 14, 2020, the PTAB declared an interference (U.S. Interference No. 106,126) between 14 U.S. patents and two U.S. patent applications (U.S. Patent Nos. 8,697,359; 8,771,945; 8,795,965; 8,865,406; 8,871,445; 8,889,356; 8,889,418; 8,895,308; 8,906,616; 8,932,814; 8,945,839; 8,993,233; 8,999,641; and 9,840,713, and U.S. Serial Nos. 14/704,551 and 15/330,876) that are co-owned by the Boston Licensing Parties, which we have an option to under the Editas License Agreement, and one U.S. patent application (U.S. Serial No. 14/685,510) that is owned by Toolgen, Inc, or Toolgen. In the declared interference, the Boston Licensing Parties have been designated as the junior party and Toolgen has been designated as the senior party. In March 2021, the PTAB issued an order on preliminary motions, granting, in part, and denying, in part, certain motions proposed by the Boston Licensing Parties and Toolgen. An oral hearing in the priority phase of U.S. Interference No. 106,126 was held on September 12, 2022. On September 28, 2022, the PTAB issued a decision on preliminary motions denying or dismissing certain motions proposed by the Boston Licensing Parties and Toolgen and issued an order suspending proceedings in the priority phase of the interference. We cannot predict with any certainty when a decision will be made. The 14 U.S. patents and two U.S. patent applications co-owned by the Boston Licensing Parties involved in U.S. Interference No. 106,126 generally relate to CRISPR/Cas9 systems or eukaryotic cells comprising CRISPR/Cas9 systems having fused or covalently linked RNA and the use thereof in eukaryotic cells.

On June 21, 2021, the PTAB declared an interference (U.S. Interference No. 106,133) between the same 14 U.S. patents and two U.S. patent applications (U.S. Patent Nos. 8,697,359; 8,771,945; 8,795,965; 8,865,406; 8,871,445; 8,889,356; 8,889,418; 8,895,308; 8,906,616; 8,932,814; 8,945,839; 8,993,233; 8,999,641; and 9,840,713, and U.S. Serial Nos. 14/704,551 and 15/330,876, co-owned by the Boston Licensing Parties) as named in the interference with Toolgen, and one U.S. patent application (U.S. Serial No. 15/456,204) that is owned by Sigma-Aldrich Co., LLC, or Sigma-Aldrich. In the declared interference, the Boston Licensing Parties have been designated as the junior party and Sigma-Aldrich has been designated as the senior party. In September 2021, the PTAB issued an order on preliminary motions, granting, deferring, dismissing, or denying, certain motions proposed by the Boston Licensing Parties and Sigma-Aldrich. An oral hearing in the priority phase of U.S. Interference No. 106,133 has been scheduled for November 16, 2022. Although the hearing typically precedes a decision by the PTAB, we cannot predict with any certainty when a decision will be made.

We or our licensors may also be subject to claims that former employees, collaborators, or other third parties have an interest in our owned patents or patent applications or in-licensed patents or patent applications or other intellectual property as an inventor or co-inventor. If we are unable to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patent applications, such co-owners may be able to license their rights to other third parties, including our competitors. In addition, we may need the cooperation of any such co-owners to enforce any patents that issue from such patent applications against third parties, and such cooperation may not be provided to us.

If we or our licensors are unsuccessful in any interference proceedings or other priority, validity (including any patent oppositions), or inventorship disputes to which we or they are subject, we may lose valuable intellectual property rights through the loss of one or more of our owned, licensed, or optioned patents, or such patent claims may be narrowed, invalidated, or held unenforceable, or through loss of exclusive ownership of or the exclusive right to use our owned or in-licensed patents. In the event of loss of patent rights as a result of any of these disputes, we may be required to obtain and maintain licenses from third parties, including parties involved in any such interference proceedings or other priority or inventorship disputes. Such licenses may not be available on commercially reasonable terms or at all, or may be non-exclusive. If we are unable to obtain and maintain such licenses, we may need to cease the development, manufacture, and commercialization of one or more of the product candidates we may develop. The loss of exclusivity or the narrowing of our patent claims could limit our ability to stop others from using or commercializing similar or identical technology and product candidates. Even if we or our licensors are successful in an interference proceeding or other similar priority or inventorship disputes, it could result in substantial costs and be a distraction to management and other employees. Any of the foregoing could result in a material adverse effect on our business, financial condition, results of operations, or prospects.

The intellectual property landscape around gene editing technology, including base editing and delivery technology, is highly dynamic, and third parties may initiate legal proceedings alleging that we are infringing, misappropriating, or otherwise violating their intellectual property rights, the outcome of which would be uncertain and may prevent, delay or otherwise interfere with our product discovery and development efforts.

The field of gene editing, especially in the area of base editing technology, is still in its infancy, and no such product candidates have reached the market. Due to the intense research and development that is taking place by several companies, including us and our competitors, in this field and in the field of delivery technology, the intellectual property landscape is evolving and in flux, and it may remain uncertain for the coming years. There may be significant intellectual property related litigation and proceedings relating to our owned and in-licensed, and other third party, intellectual property and proprietary rights in the future.

Our commercial success depends upon our ability and the ability of our collaborators and licensors to develop, manufacture, market, and sell any product candidates that we may develop and use our proprietary technologies without infringing, misappropriating, or otherwise violating the intellectual property and proprietary rights of third parties. The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights as well as administrative proceedings for challenging patents, including interference, derivation, inter partes review, post grant review, and reexamination proceedings before the USPTO or oppositions and other comparable proceedings in foreign jurisdictions. We may be subject to and may in the future become party to, or threatened with, adversarial proceedings or litigation regarding intellectual property rights with respect to our base editing platform technology, delivery platform technology and any product candidates we may develop, including interference proceedings, post-grant review, inter partes review, and derivation proceedings before the USPTO and similar proceedings in foreign jurisdictions such as oppositions before the EPO. Numerous U.S. and foreign issued patents and pending patent applications that are owned by third parties exist in the fields in which we are developing our product candidates and they may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit.

As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our base editing platform technology, delivery platform technology and product candidates may give rise to claims of infringement of the patent rights of others. Moreover, it is not always clear to industry participants, including us, which patents cover various types of therapies, products or their methods of use or manufacture. We are aware of certain third-party patents and patent applications that, if issued, may be construed to cover our base editing technology, delivery technology and product candidates. There may also be third-party patents of which we are currently unaware with claims to technologies, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take many years to issue, there may be currently pending patent applications that may later result in issued patents that our product candidates may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents.

Numerous third-party U.S. and foreign issued patents and pending patent applications exist in the fields in which we are developing product candidates. Our product candidates make use of CRISPR-based technology, which is a field that is highly active for patent filings. The extensive patent filings related to CRISPR and Cas make it difficult for us to assess the full extent of relevant patents and pending applications that may cover our base editing platform technology and product candidates and their use or manufacture. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our base editing platform technology and product candidates. For example, we are aware of a patent portfolio that is co-owned by the University of California, University of Vienna and Emmanuelle Charpentier, or the University of California Portfolio, which contains multiple patents and pending applications directed to gene editing. The University of California portfolio includes, for example, U.S. Patent Nos. 10,266,850; 10,227,611; 10,000,772; 10,113,167; 10,301,651; 10,308,961; 10,337,029; 10,351,878; 10,407,697; 10,358,659; 10,358,658; 10,385,360; 10,400,253; 10,421,980; 10,415,061; 10,428,352; 10,443,076; 10,487,341; 10,513,712; 10,519,467; 10,526,619; 10,533,190; 10,550,407; 10,563,227; 10,570,419; 10,577,631; 10,597,680; 10,612,045; 10,626,419; 10,640,791; 10,669,560; 10,676,759; 10,752,920; 10,774,344; 10,793,878; 10,900,054; 10,982,230; 10,982,231; 10,988,780; 10,988,782; 11,001,863; 11,008,589; 11,008,590; 11,028,412; 11,186,849; 11,242,543; 11,274,318; 11,293,034;11,332,761; 11,401,532, 11,473,108; 11,479,794, which are expected to expire around March 2033, excluding any additional term for patent term adjustment, or PTA, or patent term extension, or PTE, and any disclaimed term for terminal disclaimers. The University of California portfolio also includes numerous additional pending patent applications. If these patent applications issue as patents, they are expected to expire around March 2033, excluding any PTA, PTE, and any disclaimed term for terminal disclaimers. As discussed above, certain applications in the University of California Portfolio are currently subject to U.S. Interference No. 106,115 with certain U.S. patents and one U.S. patent application that are co-owned by the Boston Licensing Parties to which we have an option under the Editas License Agreement. Although we have an option to exclusively license certain patents and patent applications directed to Cas9 and Cas12a from Editas, who in turn has licensed such patents from various academic institutions including Broad Institute, we do not currently have a license to such patents and patent applications. Certain members of the University of California Portfolio are being opposed in Europe by multiple parties. For example, the EPO Opposition Division has initiated opposition proceedings against European Patent Nos. EP2,800,811 B1, and EP3,241,902 B1and EP3401400 B1, which are estimated to expire in March 2033 (excluding any patent term adjustments or extensions).

The opposition procedure before the EPO allows one or more third parties to challenge the validity of a granted European patent within nine months after grant date of the European patent. Opposition proceedings may involve issues including, but not limited to, priority, patentability of the claims involved, and procedural formalities related to the filing of the patent application. As a result of the opposition proceedings, the Opposition Division can revoke a patent, maintain the patent as granted, or maintain the patent in an amended form. Most of the claims of European patent EP 2,800,811 B1 were maintained without amendment by the Opposition Division, but this decision is being appealed. In April 2021, the claims of European patent EP3,241,902 B1 were revoked in their entirety, and that decision is not being appealed. In February 2022, the claims of European patent EP3,401,400 B1 were maintained in amended form by the Opposition Division, and this decision is being appealed. If these patents are maintained by the Opposition Division with claims similar to those that are currently opposed, our ability to commercialize our product candidates may be adversely affected if we do not obtain a license to these patents. We may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be nonexclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, we may be unable to commercialize our base editing platform technology or product candidates or such commercialization efforts may be significantly delayed, which could in turn significantly harm our business.

Numerous other patents and patent applications have been filed by other third parties directed to gene editing, guide nucleic acids, PAM sequence variants, split inteins, Cas12b or gene editing in the context of immune therapy or chimeric antigen receptors.

Because of the large number of patents issued and patent applications filed in our field, third parties may allege they have patent rights encompassing our product candidates, technologies or methods. Third parties may assert that we are employing their proprietary technology without authorization and may file patent infringement claims or lawsuit against us, and if we are found to infringe such third-party patents, we may be required to pay damages, cease commercialization of the infringing technology, or obtain a license from such third parties, which may not be available on commercially reasonable terms or at all.

Our ability to commercialize our product candidates in the United States and abroad may be adversely affected if we cannot obtain a license on commercially reasonable terms to relevant third-party patents that cover our product candidates, delivery platform technology or base editing platform technology. Even if we believe third-party intellectual property claims are without merit, there is no assurance that a court would find in our favor on questions of infringement, validity, enforceability, or priority. A court of competent jurisdiction could hold that these third-party patents are valid, enforceable, and infringed, which could materially and adversely affect our ability to commercialize any product candidates we may develop and any other product candidates or technologies covered by the asserted third-party patents. In order to successfully challenge the validity of any such U.S. patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and convincing evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any such U.S. patent. If we are found to infringe a third party’s intellectual property rights, and we are unsuccessful in demonstrating that such patents are invalid or unenforceable, we could be required to obtain a license from such third party to continue developing, manufacturing, and marketing any product candidates we may develop and our technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, and it could require us to make substantial licensing and royalty payments. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, we may be unable to commercialize our base editing platform technology, delivery platform technology or product candidates or such commercialization efforts may be significantly delayed, which could in turn significantly harm our business. We also could be forced, including by court order, to cease developing, manufacturing, and commercializing the infringing technology or product candidates. In addition, we could be found liable for significant monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent or other intellectual property right. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar material adverse effect on our business, financial condition, results of operations, and prospects.

Defense of third-party claims of infringement of misappropriation, or violation of intellectual property rights involves substantial litigation expense and would be a substantial diversion of management and employee time and resources from our business. Some third parties may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations or could otherwise have a material adverse effect on our business, financial condition, results of operations and prospects. There could also be public announcements of the results of hearings, motions, or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Any of the foregoing events could have a material adverse effect on our business, financial condition, results of operations and prospects.

Third parties have asserted and may in the future assert that we, our employees, consultants, or advisors have wrongfully used or disclosed confidential information or misappropriated trade secrets.

As is common in the biotechnology and pharmaceutical industries, we employ individuals that are currently or were previously employed at universities, research institutions or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. In addition, we regularly enter into non-disclosure and confidentiality agreements to protect the proprietary positions of third parties, such as research institutions, outside scientific collaborators, CROs, third-party manufacturers, consultants, advisors, potential partners and other third parties in order to evaluate technology for potential development. Although we try to ensure that we and our employees, consultants, and advisors do not use the proprietary information or know-how of others, we have received and may in the future be subject to claims that we or these individuals have inadvertently or otherwise wrongfully used or disclosed intellectual property, including trade secrets or other proprietary information, of third parties, including any such individual’s current or former employer. Also, we have in the past and may in the future be subject to claims that these individuals are violating non-compete agreements with their former employers. We may then have to pursue litigation to defend against any of these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and, if securities analysts or investors perceive these results to be negative, that perception could have a substantial adverse effect on the price of our common stock. This type of litigation or proceeding could substantially increase our operating losses and reduce our resources available for development activities, and we may not have sufficient financial or other resources to adequately conduct this type of litigation or proceedings. For example, some of our competitors may be able to sustain the costs of this type of litigation or proceedings more effectively than we can because of their substantially greater financial resources. In any case, uncertainties resulting from the initiation and continuation of intellectual property litigation or other intellectual property related proceedings could adversely affect our ability to compete in the marketplace.

For example, we recently received correspondence from a research institution regarding a confidentiality agreement between such institution and us. The confidentiality agreement related to certain technology that we evaluated for development in connection with certain of our programs. The correspondence alleges that we breached the terms of the confidentiality agreement, misappropriated trade secret and other confidential information of such institution, engaged in unfair and deceptive trade practices, and were unjustly enriched in connection with developing our therapeutics, including BEAM-102 and our Alpha-1 Antitrypsin Deficiency therapeutic candidate (which we now refer to as BEAM-302). The research institution claims that it is entitled to monetary damages (including damages for the apportioned value of our company and enhanced damages for an alleged willful violation) and certain ongoing royalty and/or milestone payments related to the technology that is the subject of the alleged breaches of contract, among other possible remedies. We made a settlement proposal, which was rejected, and we expect to continue to engage in communication with the research institution. We cannot predict whether we will be able to reach a settlement relating to such claims or whether we would prevail in any litigation or action related to them. Moreover, any litigation may result in negative publicity, regardless of its outcome, and may subject us to significant liability for monetary damages and have a material adverse effect on our business, financial position, and results of operations.
