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.

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

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

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:

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 Contracts with 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.

Collaboration and Other Research and Development Revenues

Collaboration and other research and development revenues decreased by $5.8 million, to $19.7 million for the year ended December 31, 2022, from $25.5 million for the year ended December 31, 2021. The decrease was primarily attributable to fewer programs licensed under our collaboration with BMS in 2022 than in 2021.

Research and Development Expenses

Research and development expenses increased by $32.5 million, to $175.0 million for the year ended December 31, 2022 from $142.5 million for the year ended December 31, 2021.

Total Other Income, Net

For the years ended December 31, 2022, and 2021, total other income, net was $5.5 million and $0.6 million, respectively, which was primarily attributable to interest income and accretion of discounts associated with marketable securities.

Comparison of Years Ended December 31, 2021 and 2020

For a discussion of our results of operations for the year ended December 31, 2021 as compared to 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.

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.

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:

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.
