Overview

We are a clinical stage genome editing company dedicated to developing potentially transformative genomic medicines to treat a broad range of serious diseases. We have developed a proprietary gene editing platform based on CRISPR technology and we continue to expand its capabilities. Our product development strategy is to target diseases where gene editing can be used to enable or enhance therapeutic outcomes for patients, while maximizing probability of technical, regulatory and commercial success. We are focused on advancing gene editing medicines to treat hemoglobinopathies, beginning with the continued development of our current ex vivo EDIT-301 program and leveraging the insights gained from this program to pursue next generation in vivo gene editing medicines targeting hematopoietic stem cells (“HSCs”). In parallel, we are pursuing the development of in vivo gene editing medicines for other organs and tissues that we believe will significantly differentiate our genome editing approach from the current standards of care for serious diseases. As part of these efforts, we are using existing strategic partnerships and collaborations and pursuing further opportunities to extend the reach of our intellectual property portfolio and access complementary technologies to expedite our drug discovery and clinical execution objectives.

Our lead program, EDIT-301, is an experimental ex vivo gene-edited medicine to treat sickle cell disease (“SCD”), a severe inherited blood disease that causes premature death, and transfusion-dependent beta thalassemia (“TDT”), the most severe form of beta-thalassemia, another inherited blood disorder characterized by severe anemia. In the second quarter of 2022, we dosed the first patient in our Phase 1/2 clinical trial of EDIT-301, which we refer to as our RUBY trial, for the treatment of severe SCD, and in December 2022, announced initial clinical data from the first two patients treated in the RUBY trial. This clinical data supports human proof of concept by showing that EDIT-301 could safely increase expression of fetal hemoglobin to clinically meaningful levels and correct anemia in SCD patients. For additional information regarding these clinical data, please see “Business—Our Gene Editing Medicine Programs—Hemoglobinopathies.” After completing sequential dosing of the first two patients, we have commenced parallel patient dosing in this trial and are on track to dose 20 total patients by the end of 2023. We expect to provide clinical updates from the RUBY trial in mid-2023 and end of 2023.

Table of Contents

In December 2021, the FDA cleared our Investigational New Drug (“IND”) application for a Phase 1/2 clinical trial of EDIT-301 for the treatment of TDT. This trial, referred to as our EDITHAL trial, is designed to assess the safety, tolerability, and preliminary efficacy of EDIT-301 for the treatment of TDT. We are on track to dose the first patient in this trial in the first quarter of 2023. We expect to provide data on this patient by the end of 2023.

We are also pursuing the development of next generation in vivo administered gene editing medicines, in which the medicine is injected or infused into the patient to edit the cells inside their body. We are initially focused on editing HSCs through targeted delivery of our AsCas12a enzyme to our clinically validated HBG1 and HBG2 promotor site. We are also in the discovery stage in developing in vivo gene editing medicines for other organs and tissues.

We previously achieved human proof of concept for our most advanced in vivo gene editing medicine for inherited retinal diseases, EDIT-101 to treat Leber congenital amaurosis. In November 2022 we announced updated clinical data from our Phase 1/2 BRILLIANCE trial of EDIT-101. This data demonstrated a favorable safety profile and provided proof of concept. However, we were not able to identify any baseline characteristics of the treatment responder patients that could pre-select a responder patient population other than zygosity. The identified responder patient population was determined to be too small to progress the program independently. We have since paused patient enrollment in this program.

We are pursuing the right combination of gene editing and targeted delivery tools through internal development and the in-licensing of complementary technologies, while also leveraging our intellectual property portfolio to drive potential out-licensing and partnership discussions that can accelerate the achievement of our goal of delivering lifesaving medicines to patients with previously untreatable or under-treated diseases. In cellular therapy medicines, we are leveraging new and existing partnerships to progress engineered cell medicines to treat various cancers. We are advancing alpha-beta T-cell experimental medicines for the treatment of solid and liquid tumors in collaboration with Bristol Myers Squibb Company (“BMS”) through its wholly owned subsidiary, Juno Therapeutics, Inc. (“Juno Therapeutics”). This collaboration, which leverages our Cas9 and AsCas12a platform technologies, has resulted in 11 programs. We have also entered into a non-exclusive collaboration and licensing agreement with Immatics N.V. to combine gamma-delta T cell adoptive cell therapies and gene editing to develop medicines for the treatment of cancer.

In January 2023, we announced the sale of our wholly owned oncology assets to Shoreline Biosciences, Inc. (“Shoreline”). Under the agreement, Shoreline acquired EDIT-202, our preclinical multiplexed edited induced human pluripotent stem cell (“iPSC”)-derived natural killer (“iNK”) cell medicine for the treatment of solid tumors, as well as an additional iNK program under development and certain related manufacturing technologies. We also exclusively licensed to Shoreline our rights to a proprietary knock-in gene editing technology referred to as SLEEK (SeLection by Essential-gene Exon Knock-in) for use in Shoreline’s iNK platform and for oncology in Shoreline’s iPSC-derived macrophage platform, as well as a non-exclusively licensed our AsCas12a gene editing technology. We believe that this transaction will enable this oncology program to more rapidly move towards clinical applications.

Since our inception in September 2013, our operations have focused on organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio, assembling our core capabilities in gene editing, seeking to identify potential product candidates, and undertaking preclinical studies. Except for EDIT-301, all of our ongoing research programs are still in the preclinical or research stage of development and the risk of failure of all of our research programs is high. We have not generated any revenue from product sales. We have primarily financed our operations through various equity financings and payments received under our research collaboration with BMS and our former strategic alliance with Allergan Pharmaceuticals International Limited (together with its affiliates, “Allergan”), which was terminated in August 2020.

Since inception, we have incurred significant operating losses. Our net losses were $220.4 million, $192.5 million, and $116.0 million for the years ended December 31, 2022, 2021 and 2020 respectively. As of December 31, 2022, we had an accumulated deficit of $1.1 billion. We expect to continue to incur significant expenses and operating losses for the foreseeable future. Our net losses may fluctuate significantly from quarter to quarter and from year to year. We anticipate that our expenses will increase substantially as we continue our current research programs and our preclinical development activities; progress the clinical development of EDIT-301; seek to identify additional research programs and additional product candidates; initiate preclinical testing and clinical trials for other product candidates we

107

Table of Contents

identify and develop; maintain, expand, and protect our intellectual property portfolio, including reimbursing our licensors for such expenses related to the intellectual property that we in-license from such licensors; further develop our genome editing platform; hire additional clinical, quality control, and scientific personnel; and incur additional costs associated with operating as a public company. We do not expect to be profitable for the year ending December 31, 2023 or the foreseeable future.

We did not experience any significant impact on our financial condition, results of operations or liquidity due to the COVID-19 pandemic during the year ended December 31, 2022. At its height, the COVID-19 pandemic had a significant negative effect on the global economy, supply chains and labor force participation, and created significant volatility in financial markets. The extent of the future impact of the COVID-19 pandemic on our operational and financial performance, including our ability to timely advance our clinical trials and preclinical actvtivies, will depend on future developments, including the duration, spread and severity of the pandemic, any evolution of the virus, government restrictions imposed in response, and the availability and effectiveness of vaccines and treatment options, all of which are uncertain and cannot be predicted. We will continue to monitor and respond to the changing conditions created by the pandemic, with focus on prioritizing the health and safety of our employees and maintaining safe and reliable operations of our facilities.

Financial Operations Overview

Revenue

To date, we have not generated any revenue from product sales and we do not expect to generate any revenue from product sales for the foreseeable future. In connection with our collaboration with BMS, we have received an aggregate of $130.0 million in payments, which have primarily consisted of the initial upfront and amendment payments, development milestone payments and research funding support. We no longer receive research funding support. During the year ended December 31, 2022, we recognized $18.8 million of revenue related to our collaboration with BMS of which $11.3 million was previously deferred revenue. As of December 31, 2022, we had $56.7 million of deferred revenue related to BMS, of which $56.7 million is classified as long-term on our consolidated balance sheet. Under this collaboration, we will recognize revenue upon delivery of option packages to BMS or when milestones are achieved. As such, we expect that our revenue will fluctuate from quarter-to-quarter and year-to-year as a result of the timing of when these events occur.

In connection with our former strategic alliance with Allergan, we received an aggregate of $130.0 million in payments, which consisted of the initial upfront payment, an option exercise payment and a milestone payment. Prior to the termination of our agreements with Allergan, certain of these payments were deferred and were being recognized over the remaining contract term using the proportional performance method. During the third quarter of 2020, as a result of the termination of our agreements with Allergan, we recognized $63.2 million of revenue that consisted of previously deferred revenue net of a payment made to Allergan in connection with the termination.

For additional information about our revenue recognition policy related to the BMS collaboration or the Allergan strategic alliance, see “—Critical Accounting Policies and Estimates—Revenue Recognition” included in this Annual Report on Form 10-K.

For the foreseeable future we expect substantially all of our revenue will be generated from our collaboration with BMS, and any other collaborations or agreements we may enter into.

Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research, preclinical development, process and scale-up development, manufacture and clinical development of our product candidates, and

108

Table of Contents

the performance of development activities under our collaboration agreements. These costs are expensed as incurred and include:

● costs incurred under clinical trial agreements with investigative sites;

● facility costs including rent, depreciation, and maintenance expenses; and

At this time, we cannot reasonably estimate or know the nature, timing, and estimated costs of the efforts that will be necessary to complete the development of any product candidates we may identify and develop. This is due to the numerous risks and uncertainties associated with developing such product candidates, including the uncertainty of:

● successful enrollment in, and completion of, clinical trials;

● receipt of marketing approvals from applicable regulatory authorities;

● effectively competing with other therapies and treatment options;

● a continued acceptable safety profile following approval;

● achieving desirable medicinal properties for the intended indications.

A change in the outcome of any of these variables with respect to the development of any product candidates we develop would significantly change the costs, timing, and viability associated with the development of that product candidate.

109

Table of Contents

Research and development activities are central to our business model. We expect research and development costs to increase significantly for the foreseeable future as our development programs progress, including as we continue to progress our clinical trials as well as support preclinical studies for our other research programs.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation for personnel in executive, finance, investor relations, business development, legal, corporate affairs, information technology, facilities and human resource functions. Other significant costs include corporate facility costs not otherwise included in research and development expenses, legal fees related to intellectual property and corporate matters, and fees for accounting and consulting services.

We anticipate that our general and administrative expenses will increase in the future to support continued research and development activities and potential commercialization of any product candidates we identify and develop. These increases will include increased costs related to the hiring of additional personnel and fees to outside consultants. We also anticipate increased expenses related to reimbursement of third-party patent-related expenses and expenses associated with operating as a public company, including costs for audit, legal, regulatory, and tax-related services, director and officer insurance premiums, and investor relations costs. With respect to reimbursement of third-party intellectual property-related expenses specifically, given the ongoing nature of the opposition and interference proceedings involving the patents licensed to us under our license agreement with The Broad Institute, Inc. (“Broad”) and the President and Fellows of Harvard College (“Harvard”), we anticipate general and administrative expenses will continue to be significant.

Other Income (Expense), Net

For the years ended December 31, 2022, and 2021, other income (expense), net consisted primarily of changes in interest income and accretion of discounts associated with other marketable securities.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles. The preparation of our consolidated financial statements requires us to make judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses, and the disclosure of contingent assets and liabilities in our consolidated financial statements. We base our estimates on historical experience, known trends and events, and various other factors that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. On an ongoing basis, we evaluate our judgments and estimates in light of changes in circumstances, facts, and experience. The effects of material revisions in estimates, if any, will be reflected in the consolidated financial statements prospectively from the date of change in estimates.

While our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we believe the following accounting policy used in the preparation of our consolidated financial statements requires the most significant judgments and estimates.

Revenue Recognition

We recognize revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), Topic 606, Revenue Recognition (“ASC 606”). Accordingly, we recognize revenue following the five step model prescribed under Accounting Standards Updates No. 2014-09, Revenue from Contractswith Customers: (i) identify contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenues when (or as) we satisfy the performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, we

110

Table of Contents

assess the goods or services promised within each contract and determine those that are performance obligations, and whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. As part of the accounting for these arrangements, we must develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. A significant portion of revenue recognized from our strategic alliance with Allergan, prior to termination, was related to research services performed for each clinical development program whereby revenue was recognized as the underlying services were performed using a proportional performance model. Prior to the termination of the arrangement with Allergan, we measured proportional performance based on full time employee hours incurred relative to projected full time employee hours to complete the research services for each clinical development program. We evaluated the measure of progress each reporting period and, if necessary, adjusted the measure of performance and related revenue recognition.

Amounts received prior to satisfying the revenue recognition criteria are recorded as deferred revenue in our consolidated balance sheets.

Accrued research and development expenses

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to clinical research organizations, to investigative sites in connection with clinical trials, to sponsored research organizations, to service providers in connection with preclinical development activities and to service providers related to product manufacturing, development and distribution of clinical supplies.

We base our accrued expenses related to clinical trials on our estimates of the services performed and efforts expended pursuant to our contractual arrangements, including those with clinical research organizations. The financial terms of these agreements are sometimes subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our service providers will exceed the level of services performed and result in a prepayment of the clinical expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid accordingly.

Although we do not expect our estimates to be materially different from expenses actually incurred, if our estimates of the status and timing of services performed differs from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. To date, there have been no material differences from our estimates to the amounts actually incurred.

Liquidity and Capital Resources

Sources of Liquidity

As of December 31, 2022, we have raised an aggregate of $898.0 million in net proceeds through the sale of shares of our common stock in public offerings and at-the-market offerings. We also have funded our business from payments received under our research collaboration with BMS and our former strategic alliance with Allergan. As of December 31, 2022, we had cash, cash equivalents and marketable securities of $437.4 million.

In May 2021, we entered into a common stock sales agreement with Cowen and Company, LLC (“Cowen”) under which we from time to time can issue and sell shares of our common stock through Cowen in at-the-market offerings for aggregate gross sale proceeds of up to $300.0 million (the “ATM Facility”). We have not sold any shares of our common stock under this ATM Facility as of the date of this Annual Report on Form 10-K.

In addition to our existing cash, cash equivalents and marketable securities, we are eligible to earn milestone and other payments under our collaboration agreement with BMS. Our ability to earn the milestone payments and the timing of earning these amounts are dependent upon the timing and outcome of our development, regulatory and commercial activities and, as such, are uncertain at this time. As of December 31, 2022, our right to contingent payments under our collaboration agreement with BMS is our only significant committed potential external source of funds.

Net Cash Used in Operating Activities

The use of cash in all periods resulted primarily from our net losses adjusted for non-cash charges and changes in components of working capital.

Net cash used in operating activities was approximately $177.3 million for the year ended December 31, 2022, which primarily consisted of operating expenses that relate to our on-going preclinical and clinical activities, sublicense and license fees, and increased personnel costs to support our expanding operations.

Net cash used in operating activities was approximately $163.8 million for the year ended December 31, 2021, which primarily consisted of operating expenses that relate to our on-going preclinical and clinical activities, a success payment that was settled in cash during the year, patent costs and license fees, rent expenses and increased costs as a result of staffing needs due to our expanding operations. These expenses were partially offset by cash inflows from license fees received in the period.

Net Cash Provided by (Used in) Investing Activities

Net cash provided by investing activities was approximately $114.1 million for the year ended December 31, 2022, primarily related to proceeds from maturities of marketable securities of $433.4 million, partially offset by costs used to acquire marketable securities of $315.2 million and purchases of property and equipment of $4.1 million.

Net cash used in investing activities was approximately $54.5 million for the year ended December 31, 2021, primarily related to costs to acquire marketable securities of $409.0 million and purchases of property and equipment of $8.0 million, partially offset by proceeds from maturities of marketable securities of $362.4 million.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was approximately $1.3 million for the year ended December 31, 2022 primarily related to proceeds received from issuance of common stock under our employee stock purchase plan and exercises of options for our common stock.

Net cash provided by financing activities was approximately $282.1 million for the year ended December 31, 2021 and consisted of $249.5 million in net proceeds received from the offering of our common stock in the first quarter 2021 and $31.5 million in proceeds received from exercises of options for our common stock.

For a discussion of our cash flows for the year ended December 31, 2020, see Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in our annual report on Form 10-K for the year ended December 31, 2021, which was filed with the SEC on February 24, 2022.

Table of Contents

Funding Requirements

We expect our expenses to increase in connection with our ongoing activities, particularly as we progress the clinical development of EDIT-301; further advance our research programs and our preclinical development activities; seek to identify product candidates and additional research programs; initiate preclinical testing and clinical trials for other product candidates we identify and develop; maintain, expand, and protect our intellectual property portfolio, including reimbursing our licensors for expenses related to the intellectual property that we in-license from such licensors; hire additional clinical, quality control, and scientific personnel; and incur costs associated with operating as a public company. In addition, if we obtain marketing approval for any product candidate that we identify and develop, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution to the extent that such sales, marketing, and distribution are not the responsibility of a collaborator. We do not expect to generate significant recurring revenue unless and until we obtain regulatory approval for and commercialize a product candidate. Furthermore, since 2016 we have incurred, and in future years we expect to continue to incur, significant costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce, or eliminate our research and development programs or future commercialization efforts.

We expect that our existing cash, cash equivalents and marketable securities at December 31, 2022 will fund our operating expenses and capital expenditure requirements into 2025. Our forecast of the period of time through which our existing cash and cash equivalents and investments will be adequate to support our operations is a forward-looking statement and involves significant risks and uncertainties. We have based this forecast on assumptions that may prove to be wrong, and actual results could vary materially from our expectations, which may adversely affect our capital resources and liquidity. We could utilize our available capital resources sooner than we currently expect. The amount and timing of future funding requirements, both near- and long-term, will depend on many factors, including, but not limited to:

● the success of our collaboration with BMS;

● the extent to which we acquire or in-license other medicines and technologies;

116

Table of Contents

● the costs of operating as a public company.

Identifying potential product candidates and conducting preclinical studies and clinical trials is a time-consuming, expensive, and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, any product candidate that we identify and develop, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of genomic medicines that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.

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. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our stockholders. 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 funds 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 to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations

As of December 31, 2022, we had non-cancelable operating leases with total future minimum lease payments of $54.0 million, of which $14.5 million will be payable in 2023. These minimum lease payments exclude our share of the facility operating expenses, real-estate taxes and other costs that are reimbursable to the landlord under the leases.

Our agreements with certain institutions to license intellectual property include potential milestone and success fees, sublicense fees, royalty fees, licensing maintenance fees, and reimbursement of patent maintenance costs that we may be required to pay. Our agreements to license intellectual property include potential milestone payments that are dependent upon the development of products using the intellectual property licensed under the agreements and contingent upon the achievement of development or regulatory approval milestones, as well as commercial milestones. These potential obligations are contingent upon the occurrence of future events and the timing and likelihood of such potential obligations are not known with certainty. For further information regarding these agreements, please see “Business—Our Collaborations and Licensing Strategy.”

We also enter into contracts in the normal course of business with contract research organizations, contract manufacturing 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 at any time upon prior notice.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. As of December 31, 2022, we had cash and cash equivalents of $141.5 million, primarily held in money market mutual funds consisting of U.S. government-backed securities, and marketable securities of $295.8 million, primarily consisting of U.S. government-backed securities, commercial paper and corporate debt securities. 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, including cash equivalents, are in the form, or may be in the form of, money market funds or marketable securities and are or may be

invested in U.S. Treasury and U.S. government agency obligations. Due to the short-term maturities and low risk profiles of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our investments.

While we contract with certain vendors and institutions internationally, substantially all of our total liabilities as of December 31, 2022 were denominated in the United States dollar and we believe that we do not have any material exposure to foreign currency exchange rate risk.

Notes to Consolidated Financial Statements

1. Nature of Business

Editas Medicine, Inc. (the “Company”) is a clinical stage genome editing company dedicated to developing potentially transformative genomic medicines to treat a broad range of serious diseases. The Company was incorporated in the state of Delaware in September 2013. Its principal offices are in Cambridge, Massachusetts.

Since its inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, and raising capital. The Company has primarily financed its operations through various equity financings, payments received under a research collaboration with Juno Therapeutics, a wholly-owned subsidiary of the Bristol-Myers Squibb Company (“BMS”), and payments received under a strategic alliance and option agreement with Allergan Pharmaceuticals International Limited (together with its affiliates, “Allergan”).

The Company is subject to risks common to companies in the biotechnology industry, including but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any drug product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations and ability to transition from pilot-scale manufacturing to large-scale production of products.

Liquidity

As of December 31, 2022, we have raised an aggregate of $898.0 million in net proceeds through the sale of shares of our common stock in public offerings and at-the-market offerings. We also have funded our business from payments received under our research collaboration with BMS and our former strategic alliance with Allergan. As of December 31, 2022, we had cash, cash equivalents and marketable securities of $437.4 million.

In May 2021, the Company entered into a common stock sales agreement with Cowen and Company, LLC (“Cowen”), under which the Company from time to time can issue and sell shares of its common stock through Cowen in at-the-market offerings for aggregate gross sale proceeds of up to $300.0 million (the “ATM Facility”). As of December 31, 2022 the Company has not sold any shares of its common stock under the ATM Facility.

The Company has incurred annual net operating losses in every year since its inception. The Company has an accumulated deficit of $1.1 billion at December 31, 2022. The Company expects that its existing cash, cash equivalents and marketable securitieson December 31, 2022 fund its operating expenses and capital expenditure requirements into 2025.The Company will require substantial additional capital to fund its operations. The Company has never generated any product revenue. There can be no assurance that the Company will be able to obtain additional debt or equity financing or generate product revenue or revenues from collaborative partners, on terms acceptable to the Company, on a timely basis or at all. The failure of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s business, results of operations, and financial condition.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Editas Medicine, Inc. and its wholly owned subsidiary, Editas Securities Corporation, which is a Delaware subsidiary created to buy, sell and hold securities. All intercompany transactions and balances have been eliminated.

127

Table of Contents

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, the Company’s management evaluates its estimates, which include, but are not limited to, estimates related to revenue recognition, stock-based compensation expense, the accrual for research and development expenses, valuations of in-process research and development assets and deferred tax valuation allowances. The Company bases its estimates on historical experience and other market-specific or relevant assumptions that it believes to be reasonable under the circumstances. Actual results may differ from those estimates or assumptions.

Fair Value of Financial Instruments

ASC Topic 820, Fair Value Measurement (“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

ASC 820 identifies fair value as the exchange price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following:

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, restricted cash, marketable securities, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses, and other current liabilities approximate their fair values, due to their short-term nature.

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid investments purchased with original maturities of 90 days or less at acquisition to be cash equivalents. Cash and cash equivalents include cash held in banks and amounts held in money market funds.

128

Table of Contents

The Company has restricted cash of $3.9 million held as collateral for the Company’s office and lab facilities and credit card program. The restricted funds are maintained in a traditional bank account.

The following table presents cash, cash equivalents, and restricted cash as reported on the consolidated balance sheets that equal the total amounts on the consolidated statements of cash flows (in thousands):

​ ​ ​ ​ ​ ​ ​

​ ​ Year Ended

​ ​ December 31,

Total cash, cash equivalents, and restricted cash ​ $ 145,399 ​ $ 207,396

Marketable Securities

The Company classifies marketable securities with a remaining maturity when purchased of greater than three months and less than one year from the balance sheet date as current. Marketable securities are classified as long-term assets on the consolidated balance sheets if the contractual maturity exceeds one year and the Company does not intend to utilize the marketable securities to fund current operations. For the years ended December 31, 2022 and 2021, the Company’s marketable securities consisted of investments in available-for-sale debt securities.

Available-for-sale debt securities are carried at fair value with the unrealized gains and losses included in other comprehensive loss as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income and/or expense over the life of the of the underlying security. Realized gains and losses are included in other income (expense).

At each reporting date, the Company records an allowance for credit losses and reports it as credit loss expense which is included in “Other income (expense), net” in the Company’s consolidated statement of operations. The estimate for credit losses includes a measure of the expected risk of credit loss even if the risk is remote. When assessing financial assets for credit losses, the Company pools financial assets with similar risk characteristics and performs a collective evaluation. A credit loss on an available-for-sale debt security is limited to the difference in fair value and the amortized cost. A previously recognized credit loss may be increased or decreased in subsequent periods if the Company’s estimate of fair value changes. To determine whether to record a credit loss, the Company considers issuer or vendor specific credit ratings and historical losses as well as current economic conditions and its expectations for future economic conditions. To date, the Company has not had any credit losses, and the Company did not have an allowance for credit losses as of December 31, 2022 and 2021.

During 2021, the Company’s marketable securities also included corporate equity securities. The Company classified investments in equity securities that had a readily determinable fair value as marketable securities in the Company’s consolidated balance sheets. The fair value of these securities were based on a quoted price for an identical equity security. If the equity security had a restriction that was determined to be an attribute of the security that would transfer to a market participant, the fair value of the security was measured based on the quoted price for an otherwise identical unrestricted equity security, adjusted for the effect of the restriction. The adjustment reflects the discount that a market participant would demand for the risk relating to the inability to dispose of the security for a specified period of time. The Company recorded changes in the fair value of its equity securities in “Other income (expense), net” in the Company’s consolidated statement of operations.

Accounts Receivable

The Company makes judgments as to its ability to collect outstanding receivables and provides an allowance for receivables when collection becomes doubtful. The Company's receivables primarily relate to amounts reimbursed under its collaboration agreements. The Company believes that credit risk associated with its collaborations partners is not significant. To date, the Company has not had any write-offs of bad debt, and the Company did not have an allowance for doubtful accounts as of December 31, 2022 and 2021.

129

Table of Contents

Concentrations of Credit Risk and Off-Balance Sheet Risk

The Company has no financial instruments with off-balance sheet risk such as foreign exchange contracts, option contracts, or other foreign hedging arrangements. Financial instruments that potentially subject the Company to a concentration of credit risk are cash, cash equivalents, marketable securities and receivables owed to the Company from collaboration partners. The Company’s cash, cash equivalents and marketable securities are held in accounts at a financial institution that may exceed federally insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds.

Property and Equipment

Property and equipment consists of computers, laboratory equipment, furniture and office equipment, and leasehold improvements and is stated at cost, less accumulated depreciation. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed to operations as incurred, while costs of major additions and betterments are capitalized. Depreciation is calculated over the estimated useful lives of the assets using the straight-line method. The Company capitalizes laboratory equipment used for research and development if it has alternative future use in research and development or otherwise.

​ ​ ​ ​

Asset: Estimated Useful life

Lab equipment 5 years ​

Computer equipment and software 3 years ​

Furniture and equipment 5 years ​

Leasehold improvements Shorter of useful life or remaining lease term ​

Impairment of Long-lived Assets

The Company evaluates long-lived assets for potential impairment when events or changes in circumstances indicate the carrying value of the assets may not be recoverable. Recoverability is measured by comparing the book values of the assets to the expected future net undiscounted cash flows that the assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the book values of the assets exceed their fair value. The Company has not recognized any impairment losses from inception through December 31, 2022.

Profit-Sharing Arrangements

The Company considers the nature and contractual terms of the arrangements and assesses whether such arrangements involve a joint operating activity pursuant to which the Company is an active participant and is exposed to significant risks and rewards with respect to such arrangement. If the Company is an active participant and is exposed to significant risks and rewards with respect to such arrangement, the Company accounts for such arrangement as a collaboration under ASC Topic 808, Collaborative Arrangements (“ASC 808”). ASC 808 describes arrangements within its scope and considerations surrounding presentation and disclosure, with recognition matters subjected to other authoritative guidance, in certain cases by analogy.

Payments received from a collaboration partner to which this policy applies are recorded as contra-expense in the applicable period and may include development costs or patent expense reimbursements. The Company classifies payments made under the cost sharing provisions of such arrangements as a component of research and development expenses to reflect the joint risk sharing nature of such profit-sharing arrangements. The Company classifies payments owed or receivables recorded as other current liabilities or prepaid expenses and other current assets, respectively, in the Company’s consolidated balance sheets. The Company had one agreement that was accounted for in accordance with ASC 808 prior to the termination of the arrangement during the year ended 2020. The arrangements and payments are described more fully in Note 9.

Table of Contents

Revenue Recognition

The Company recognizes revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company enters into collaboration agreements and certain other agreements that are within the scope of ASC 606, under which the Company licenses, may license or grants an option to license rights to certain of the Company’s product candidates and performs research and development services in connection with such arrangements. The terms of these arrangements typically include payment of one or more of the following: non-refundable, up-front fees; reimbursement of research and development costs; development, clinical, regulatory and commercial sales milestone payments; and royalties on net sales of licensed products.

Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of ASC 606, the Company performs the following five steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect consideration it is entitled to in exchange for the goods or services it transfers to the customer.

The promised goods or services in the Company’s arrangements typically consist of a license, or option to license, rights to the Company’s intellectual property or research and development services. The Company provides options to additional items in such arrangements, which are accounted for as separate contracts when the customer elects to exercise such options, unless the option provides a material right to the customer. Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer and are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. In assessing whether promised good or services are distinct, the Company considers factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on its own or whether the required expertise is readily available and whether the goods or services are integral or dependent to other goods or services in the contract.

The Company estimates the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. The consideration may include fixed consideration or variable consideration. At the inception of each arrangement that includes variable consideration, the Company evaluates the amount of potential payment and the likelihood that the payments will be received. The Company utilizes either the most likely amount method or expected value method to estimate the amount expected to be received based on which method best predicts the amount expected to be received. The amount of variable consideration that is included in the transaction price may be constrained and is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period.

The Company’s contracts often include development and regulatory milestone payments that are as assessed under the most likely amount method and constrained if it is probable that a significant revenue reversal would occur. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company re-evaluates the probability of achievement of such development and clinical milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect collaboration and other research and development revenues in the period of adjustment.

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty

131

Table of Contents

has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue resulting from any of the Company’s collaboration or strategic alliance arrangements.

The Company allocates the transaction price based on the estimated standalone selling price. The Company must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the stand-alone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs. Variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated are consistent with the amounts the Company would expect to receive for the satisfaction of each performance obligation.

The consideration allocated to each performance obligation is recognized as revenue when control is transferred for the related goods or services. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

The Company receives payments from its customers based on billing schedules established in each contract. Up-front payments and fees are recorded as deferred revenue upon receipt or when due until the Company performs its obligations under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.

Research and Development Expenses

Research and development expenses are charged to expense as incurred in performing research and development activities. The costs include employee-related expenses including salaries, benefits, and stock-based compensation expense, costs of funding research performed by third parties that conduct research and development and preclinical and clinical activities on the Company’s behalf, the cost of purchasing lab supplies and non-capital equipment used in preclinical and clinical activities and in manufacturing preclinical and clinical study materials, consultant fees, facility costs including rent, depreciation, and maintenance expenses, and fees for acquiring and maintaining licenses under third party licensing agreements which are typically expensed when incurred if the technology licensed has no alternate future uses, including any sublicensing or success payments made to the Company’s licensors. In accruing service fees, the Company estimates the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the Company’s estimate, the accrual or prepaid is adjusted accordingly. The Company defers and capitalizes non-refundable advance payments made by the Company for research and development activities until the related goods are received or the related services are performed. In circumstances where amounts have been paid in excess of costs incurred, the Company records a prepaid expense.

In-process Research and Development Assets

In-process research and development assets that are acquired in a transaction that does not qualify as a business combination under GAAP and that do not have an alternative future use are expensed in the period in which the assets are acquired.

132

Table of Contents

Patent Costs

The Company expenses patent and patent application costs and related legal costs for the prosecution and maintenance of such patents and patent applications, including patents and patent applications the Company in-licenses, as incurred, and classifies such costs as general and administrative expenses in the accompanying consolidated statements of operations.

Leases

The Company accounts for leases in accordance with ASC 842. At the inception of an arrangement the Company determines whether the arrangement contains a lease. If a lease is identified in an arrangement, the Company recognizes a right-of-use asset and liability on its balance sheet and determines whether the lease should be classified as a finance or operating lease. The Company does not recognize assets or liabilities for leases with lease terms of less than 12 months. Lease payments for short-term leases are recorded to operating expense on a straight-line basis over the lease term and variable lease payments are recorded in the period in which the obligation for those payments is incurred.

A lease qualifies as a finance lease if any of the following criteria are met at the inception of the lease: (i) there is a transfer of ownership of the leased asset to the Company by the end of the lease term, (ii) the Company holds an option to purchase the leased asset that it is reasonably certain to exercise, (iii) the lease term is for a major part of the remaining economic life of the leased asset, (iv) the present value of the sum of lease payments equals or exceeds substantially all of the fair value of the leased asset, and (v) the nature of the leased asset is specialized to the point that it is expected to provide the lessor no alternative use at the end of the lease term. All other leases are recorded as operating leases.

Finance and operating lease assets and liabilities are recognized at the lease commencement date based on the present value of the lease payments over the lease term using the discount rate implicit in the lease. If the rate is not readily determinable, the Company utilizes its incremental borrowing rate at the lease commencement date. Operating lease assets are further adjusted for prepaid or accrued lease payments. Operating lease payments are expensed using the straight-line method as an operating expense over the lease term. Finance lease assets are amortized to depreciation expense using the straight-line method over the shorter of the useful life of the related asset or the lease term. Finance lease payments are bifurcated into (i) a portion that is recorded as imputed interest expense and (ii) a portion that reduces the finance liability associated with the lease.

The Company does not separate lease and non-lease components when determining which lease payments to include in the calculation of its lease assets and liabilities. Variable lease payments are expensed as incurred. If a lease includes an option to extend or terminate the lease, the Company reflects the option in the lease term if it is reasonably certain it will exercise the option.

Stock-based Compensation Expense

The Company accounts for all stock-based awards granted to employees and non-employees as stock-based compensation expense at fair value in accordance with FASB ASC Topic 718 Compensation—Stock Compensation (“ASC 718”). The Company estimates the grant date fair value of restricted stock based on the market value of the Company’s common stock on the date of the grant. The Company estimates the grant date fair value of each option award using the Black-Scholes option-pricing model.

The Black-Scholes option pricing model requires the input of certain subjective assumptions, including (1) the expected stock price volatility, (2) the calculation of expected term of the award, (3) the risk-free interest rate, and (4) the expected dividend yield. Because there had been no public market for the Company’s common stock prior to its initial public offering, there was a lack of company-specific historical and implied volatility data. Accordingly, the Company based its estimates of expected volatility on the historical volatility of a group of similar companies that are publicly traded. The Company calculates historical volatility based on a period of time commensurate with the expected term. The Company computes expected volatility based on the historical volatility of a representative group of companies with similar characteristics to the Company, including their stages of product development and focus on the life science

industry. The Company uses the simplified method as prescribed by the Securities and Exchange Commission’s Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term for options granted to employees as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. For options granted to non-employees, the Company utilizes the contractual term of the arrangement as the basis for the expected term. The Company determines the risk-free interest rate based on a treasury instrument whose term is consistent with the expected term of the stock options. The Company uses an assumed dividend yield of zero as the Company has never paid dividends and does not have current plans to pay any dividends on its common stock.

Restricted stock awards (“RSAs”) are subject to repurchase rights. Accordingly, the Company has recorded the proceeds from the issuance of RSAs as a liability in the consolidated balance sheets. The restricted stock liability is reclassified into stockholders’ equity as the restricted stock vests.

Service-Based Awards

For stock-based awards issued to employees, non-employee service providers and members of the Company’s board of directors (the “Board”), the Company recognizes the grant date fair value of the service-based options, RSAs or restricted stock unit awards (“RSUs”) on a straight-line basis over the requisite service period, which is generally the vesting period of the respective award. If an employee or non-employee service requirement is concluded to be non-substantive, the stock-based compensation expense would be expensed immediately.

Market-Based Awards

For market-based awards, the Company recognizes the grant date fair value of the market-based options over the earlier of the derived service period, pursuant to a Monte-Carlo simulation model, or when the market-based vesting conditions are met. The Company estimates an award's derived service period based on the best estimate of the period over which an award's vesting condition(s) will be achieved. If the market-based vesting conditions are met ahead of the derived service period, the expense will be accelerated. If the market-based vesting conditions are not met and the market-based award is cancelled, the expense will not be reversed unless the market-based award is forfeited.

Performance-Based Awards

For performance-based awards, the Company recognizes the grant date fair value of the performance-based options or RSUs over the requisite service period using the accelerated attribution method to the extent achievement of the performance condition is probable. Certain awards are subject to both performance and continued service conditions.

The Company classifies stock-based compensation expense in its consolidated statement of operations and comprehensive loss in the same manner in which the award recipient’s salary or service payments are classified. Forfeitures are recorded as they occur. If factors change or different assumptions are used, the Company’s stock-based compensation expense could be materially different in the future.

Success Payments, Research Funding Payments and Notes Payables

Certain arrangements require the Company to make payments, if and when, the Company’s market capitalization reaches specified thresholds for a specific period of time or upon a sale of the Company for consideration in excess of those thresholds or above a specific amount. The payments are accounted for under the provisions of ASC 718, whereby the Company recognizes the expense and liability when it becomes probable that the amounts will become due. The Company records this expense as a research and development expense in its consolidated statements of operations. The arrangements and payments are described more fully in Note 8.

The payments are payable in either cash, common stock or promissory notes payable, depending upon the licensor and the Company’s election. If the Company elects to issue a promissory note relating to contractual obligations, the promissory note bears interest at 4.8% per annum. Outstanding principal and accrued interest on the promissory notes are typically payable on the earlier of five months or a specified period of time following a Company sale or change of control event, subject to certain exceptions.

Income taxes

Income taxes are recorded in accordance with ASC Topic 740, Income Taxes (“ASC 740”), which provides for deferred taxes using an asset and liability approach. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. The Company provides a valuation allowance against net deferred tax assets unless, based upon the weight of available evidence, it is more likely than not that the deferred tax assets will be realized.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances.

The Company assesses the impact of various tax reform proposals and modifications to existing tax treaties in all jurisdictions where they have operations to determine the potential effect on the Company’s business and any assumptions they have made about their future taxable income. The Company cannot predict whether any specific proposals will be enacted, the terms of any such proposals or what effect, if any, such proposals would have on the Company if they were to be enacted.

Beginning in 2022, the Tax Cut and Jobs Act of 2017 eliminates the currently available option to deduct research and development expenditures and requires taxpayers to amortize them over five years. The U.S. Congress is considering legislation that would defer the amortization requirement to future periods, however, the Company has no assurance that the provision will be repealed or otherwise modified.

Comprehensive Loss

Comprehensive loss currently consists of net loss and changes in unrealized gains and losses on marketable securities.

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker in deciding how to allocate resources and assess performance. The Company and the Company’s chief operating decision maker, the Company’s Chief Executive Officer, view the Company’s operations and manage the Company’s business as a single operating segment, which is the business of developing and commercializing genome editing technology.

rent payments commenced in January 2020 and continue through the term of the lease and are subject to increases over the term of the lease.

8. Commitments and Contingencies

The Company is a party to a number of license agreements under which the Company licenses patents, patent applications and other intellectual property from third parties. As such, the Company is obligated to reimburse licensors for various costs including upfront licenses fees, annual license fees, certain licensor expense reimbursements, success payments, research funding payments, and milestones triggerable upon certain development, regulatory, and commercial events as well as royalties on future products. These contracts are generally cancellable, with notice, at the Company’s option and do not have significant cancellation penalties.

Broad Sponsored Research Agreement

In 2018, the Company entered into a sponsored research agreement (the “Sponsored Research Agreement”) with The Broad Institute, Inc. (“Broad”). The Sponsored Research Agreement provides for Broad to conduct research useful or relevant to genome editing in the field of genomic medicines for the prevention or treatment of human disease with funding from the Company. Under the Sponsored Research Agreement, Broad granted to the Company an exclusive right of first negotiation for licenses from Broad with respect to patentable inventions developed by Broad in the course of the sponsored research, subject to certain limitations and retained rights (“Sponsored Invention Licenses”).

Under the Sponsored Research Agreement, the Company is obligated to make payments (“Market Cap Research Funding”) in the event the Company’s market capitalization reaches certain amounts for a specified period of time. Unless the Company has undergone a change in control, Market Cap Research Funding is payable by the Company in cash, in shares of common stock, or in the form of promissory notes, which may be settled in shares of common stock at the election of the Company. In aggregate, the Company has triggered $25.0 million in Market Cap Research Funding and has primarily settled these amounts through the issuance of shares of its common stock. The remaining $100.0 million in Market Cap Research Funding may be triggered when the Company’s market capitalization reaches various low-ten to eleven dollar amounts or in the event of a Company sale. The Company is not required to make additional Market Cap Research Funding payments if the Company, whether directly or through its affiliates or sublicensees, is not researching, developing, or commercializing products based on or incorporating inventions exclusively licensed to the Company from Broad subject to certain exclusions.

The Sponsored Research Agreement is terminable by each party upon the occurrence of specified bankruptcy events of the other party and otherwise will continue in effect until the remaining Market Cap Research Funding payments are received by Broad and such time as the Company has no further rights of first negotiation for Sponsored Invention Licenses, unless otherwise mutually agreed between the parties.

Broad & Harvard License Agreements

The Company has entered into agreements with Broad and the President and Fellows of Harvard College (“Harvard”) to license certain patent rights owned or co-owned by the institutions. The foundational patent rights that were in-licensed by the Company include Cas9-I (“Cas9-I License Agreement”), Cas12a (formerly known as Cpf1) (“Cpf1 License Agreement”), and Cas9-II (“Cas9-II License Agreement”) (collectively referred to herein as the “License Agreements”). The Company received exclusive, worldwide, royalty-bearing, sublicensable licenses to certain patent rights to develop and commercialize licensed product and a non-exclusive, worldwide, royalty-bearing sublicensable license under the same patent rights for all other purposes, subject to certain limitations and retained rights. The Company is obligated to use commercially reasonable efforts to research, develop, and commercialize licensed products. The Company is also required to achieve certain development milestones within specified time periods for products covered by the License Agreements, with Broad or Harvard, as applicable, having the right to terminate the License Agreements, on a license agreement-by-license agreement basis, if the Company fails to achieve these milestones within the required time periods. Broad or Harvard may grant licenses under specified circumstances to third parties that wish to develop and commercialize products that target a particular gene that otherwise would fall within the scope of the exclusive licenses granted to the Company, provided that the Company is not, directly or through any of its affiliates, sublicensees, or collaborators, researching, developing, or commercializing a product directed toward the same gene target, or can demonstrate to Broad’s and/or Harvard’s, as applicable, reasonable satisfaction that the Company is interested in researching, developing, and commercializing a product directed toward the same gene target, that the Company has a commercially reasonable research, development, and commercialization plan to do so, and the Company commences and continues reasonable commercial efforts under such plan. The Company has the right to terminate each of the License Agreements at will with four months written notice to Broad. Unless terminated earlier, the term of each of the License Agreements will expire on a country-by-country basis, upon the expiration of the last to expire valid claim of the licensed patent rights in such country.

Milestones

In aggregate, the Company may pay up to $14.8 million, $20.0 million, and $3.7 million in clinical and regulatory milestones under the Cas9-I License Agreement, Cpf1 License Agreement, and Cas9-II License Agreement, respectively. In addition, the Company owes aggregate sales milestones totaling $54.0 million, $54.0 million, and $13.5 million under the Cas9-I License Agreement, Cpf1 License Agreement, and Cas9-II License Agreement, respectively. If the licensed product or service prevents or treats a human disease that afflicts fewer than a specified number of patients in the aggregate in the United States (“U.S.”) or a specified number of patients per year in the U.S., the clinical and regulatory milestones reduce to $4.1 million, $5.5 million, and $1.1 million under the Cas9-I License Agreement, Cpf1 License Agreement, and Cas9-II License Agreement, respectively. In addition, the aggregated sales milestones reduce to $36.0 million, $36.0 million, and $9.0 million under the Cas9-I License Agreement, Cpf1 License Agreement, and Cas9-II License Agreement, respectively. Certain clinical and regulatory milestones are subject to a multiplier payout equivalent to a double-digit percentage in the event of a change of control.

Royalties

The Company is required to pay on a product-by-product and country-by-country basis, a mid single-digit percentage royalty on net sales of licensed products made by the Company, its affiliates, or its sublicensees. The royalty percentage depends on the product and service, and whether such licensed product or licensed service is covered by a valid claim. If the Company is legally required to pay royalties to a third party on net sales of the Company’s products because such third party holds patent rights that cover such licensed product, then the Company can credit up to a specified percentage of the amount paid to such third party against the royalties due to the institutions. Such credit may not exceed 50% of the applicable royalties paid by the Company to the applicable third party. The Company’s obligation to pay royalties will expire on a product-by-product and country-by-country basis upon the later of the expiration of the last to expire valid claim of the patent rights that covers each licensed product or service in each country or the tenth anniversary of the date of the first commercial sale of the licensed product or licensed service.
