Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Nature of Business

Editas Medicine, Inc. (the “Company”) is a leading, 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 (“Juno Therapeutics”), payments received under a strategic alliance and option agreement with Allergan Pharmaceuticals International Limited (together with its affiliates, “Allergan”), which was terminated in August 2020, and its license agreement with Beam Therapeutics.

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

In January 2021, the Company completed a public offering whereby it sold 3,500,000 shares of its common stock and received net proceeds of approximately $216.9 million. In February 2021, the underwriters in the public offering exercised their option to purchase an additional 525,000 shares, resulting in additional net proceeds to the Company of approximately $32.6 million.

The Company has incurred annual net operating losses in every year since its inception. The Company expects that its existing cash, cash equivalents and marketable securities at March 31, 2021 and anticipated interest income will enable it to fund its operating expenses and capital expenditure requirements well into 2023. The Company had an accumulated deficit of $721.9 million at March 31, 2021, and 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

Unaudited Interim Financial Information

The condensed consolidated financial statements of the Company included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “Annual Report”).

Table of Contents

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Editas Securities Corporation. All intercompany transactions and balances of the subsidiary have been eliminated in consolidation. In the opinion of management, the information furnished reflects all adjustments, all of which are of a normal and recurring nature, necessary for a fair presentation of the results for the reported interim periods. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued to provide additional evidence relative to certain estimates or to identify matters that require additional disclosure. The three months ended March 31, 2021 and 2020 are referred to as the first quarter of 2021 and 2020, respectively. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year or any other interim period.

Summary of Significant Accounting Policies

The Company’s significant accounting policies are described in Note 2, “Summary of significant accounting policies,” to the consolidated financial statements included in the Annual Report. There have been no material changes to the significant accounting policies previously disclosed in the Annual Report.

7. 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 pay 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. The terms and conditions as well as the accounting analysis for the Company’s significant commitments and contingencies are described in Note 8, “Commitments and Contingencies” to the consolidated financial statements included in the Annual Report. There have been no material changes to the terms and conditions, or the accounting conclusions previously disclosed in the Annual Report.

As such, the Company anticipates that it has a substantial commitment in connection with these proceedings until such time as these proceedings have been resolved, but the amount of such commitment is not determinable. The Company incurred an aggregate of $3.8 million in expense during both the three months ended March 31, 2021 and 2020 for such reimbursement.

10. Net Loss per Share

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock and potentially dilutive securities outstanding for the period determined using the treasury stock and if converted methods. Contingently issuable shares are included in the calculation of basic loss per share as of the beginning of the period in which all the necessary conditions have been satisfied. Contingently issuable shares are included in diluted loss per share based on the number of shares, if any, that would be issuable under the terms of the arrangement if the end of the reporting period was the end of the contingency period, if the results are dilutive.

For purposes of the diluted net loss per share calculation, stock options are considered to be common stock equivalents, but they were excluded from the Company’s calculation of diluted net loss per share allocable to common stockholders because their inclusion would have been anti-dilutive. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.

The following common stock equivalents were excluded from the calculation of diluted net loss per share allocable to common stockholders because their inclusion would have been anti-dilutive:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read together with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the Securities and Exchange Commission (“SEC”) on February 26, 2021 (the “Annual Report”).

This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “predict,” “project,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. All statements addressing our future operating performance and clinical development and regulatory timelines that we expect or anticipate will occur in the future, are forward-looking statements. There are a number of important risks and uncertainties that could cause our actual results to differ materially from those indicated by forward-looking statements, including uncertainties inherent in the initiation and completion of pre-clinical studies and clinical trials and clinical development of our product candidates; availability and timing of results from pre-clinical studies and clinical trials; whether interim results from a clinical trial will be predictive of the final results of the trial or the results of future trials; expectations for regulatory approvals to conduct trials or to market products and availability of funding sufficient for our foreseeable and unforeseeable operating expenses and capital expenditure requirements. These and other risks are described in greater detail in our Annual Report under the captions “Risk Factor Summary” and “Risk Factors,” and in other filings that we may make with the SEC in the future. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements.

The forward-looking statements contained in this Quarterly Report on Form 10-Q are made as of the date of this Quarterly Report on Form 10-Q, and we do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.

Overview

We are a leading, clinical stage genome editing company dedicated to developing potentially transformative gene-editing 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 of high unmet need where we aim to make differentiated, transformational medicines using our gene-editing platform. We are advancing in vivo gene-editing medicines, in which the medicine is injected or infused into the patient to edit the cells inside their body, ex vivo gene-edited cell medicines, in which cells collected from a patient are edited with our technology and then administered back to that same patient, and cellular therapy medicines, in which we use our technology to edit cells collected from a donor to develop medicines that can be administered to a separate patient. While our discovery efforts have ranged across several diseases and therapeutic areas, the areas where our programs are more mature are in our in vivo gene-editing medicines to treat ocular diseases, our ex vivo gene-edited cell medicines to treat hemoglobinopathies, and our cellular therapy medicines to treat cancer.

In ocular diseases, our most advanced program is designed to address a specific genetic form of retinal degeneration called Leber congenital amaurosis 10 (“LCA10”), a disease for which we are not aware of any available therapies and only one other potential treatment is in clinical trials in the United States and Europe. In mid-2019, we initiated our Phase 1/2 BRILLIANCE clinical trial for EDIT-101, an experimental gene-editing medicine to treat LCA10. We plan to enroll approximately 18 patients in the United States and Europe in up to five cohorts. We completed dosing of the first cohort, the adult low-dose cohort, in 2020. Due to an absence of severe adverse events or dose limiting toxicity in adults treated in the first cohort, the inclusion criteria of the protocol were modified to allow

inclusion of subjects with better than light perception vision only. Although we experienced slowed enrollment in 2020 for subsequent cohorts due to the ongoing impact of the COVID-19 pandemic, in the first quarter of 2021 we initiated dosing of the second cohort, the adult mid-dose cohort. We expect to announce initial clinical data from the first two cohorts by the end of 2021.

For our ex vivo gene-edited cell medicines, our lead program is EDIT-301, an experimental medicine to treat sickle cell disease, a severe inherited blood disease that causes premature death, and beta-thalassemia, another inherited blood disorder characterized by severe anemia. In December 2020, we submitted an investigational new drug application (“IND”) to the U.S. Food and Drug Administration (“FDA”) for the initiation of a Phase 1/2 clinical trial of EDIT-301, which we refer to as our RUBY trial, for the treatment of sickle cell disease. In January 2021, the FDA cleared the start of enrollment and dosing of patients in the first phase of the trial (which is designed to validate the safety and beneficial effects of the cell editing process). The RUBY trial is active and recruiting patients for enrollment. We expect to begin dosing in the RUBY trial by the end of 2021. In parallel, the FDA has imposed a partial clinical hold and requested we develop a potency assay to ensure that the characteristics of the product released are as expected and confirmed by clinical data collected in the first patients treated. We also aim to submit an IND for EDIT-301 for the treatment of beta-thalassemia by the end of 2021.

In cellular therapy medicines, we continue to develop our capabilities to generate cells from induced pluripotent stem cells to develop engineered cell medicines to treat cancer and are also advancing alpha-beta T cell experimental medicines. In May 2015, we entered into a collaboration with Juno Therapeutics, Inc., a wholly-owned subsidiary of Bristol-Myers Squibb Company (“Juno Therapeutics”), a leader in the emerging field of immuno-oncology, to develop novel engineered alpha-beta T cell therapies for cancer and autoimmune diseases, which was amended and restated in each of May 2018 and November 2019, at which time we also entered into a related license agreement with Juno Therapeutics, which we collectively refer to as our collaboration with them.

In March 2017, we entered into a strategic alliance and option agreement with Allergan Pharmaceuticals International Limited (together with its affiliates, “Allergan”) to discover, develop, and commercialize new gene editing medicines for a range of ocular disorders. In July 2018, Allergan exercised its option to develop and commercialize EDIT-101 and paid us $15.0 million in connection with such exercise (the “EDIT-101 Option Exercise Payment”). We and Allergan subsequently entered into a co-development and commercialization agreement under which we agreed to co-develop and equally split profits and losses for EDIT-101 in the United States. In December 2018, we also received a $25.0 million payment from Allergan in connection with the acceptance of the IND for EDIT-101 (the “EDIT-101 Milestone Payment”). In August 2020, we and Allergan terminated the strategic alliance and option agreement and the co-development and commercialization agreement, and we assumed full rights to EDIT-101 and responsibility for conducting the clinical trial. In connection with such termination, we and Allergan entered into a termination agreement, pursuant to which we made a one-time aggregate payment of $20.0 million to Allergan.

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-101 and EDIT-301, all of our 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 Juno Therapeutics, our strategic alliance with Allergan, and our license agreement with Beam Therapeutics.

Since inception, we have incurred significant operating losses. Our net losses were $56.7 million and $37.7 million for the three months ended March 31, 2021 and 2020, respectively. As of March 31, 2021, we had an accumulated deficit of $721.9 million. 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-101 for the treatment of LCA10 and EDIT-301 for the treatment of sickle cell disease; seek to identify additional research programs and additional product candidates; initiate preclinical testing and clinical trials for other product candidates we identify and develop; maintain, expand, and

Table of Contents

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 costs associated with operating as a public company. We do not expect to be profitable for the year ending December 31, 2021 or the foreseeable future.

Although we did not experience any significant impact on our financial condition, results of operations or liquidity due to the ongoing COVID-19 pandemic during the three months ended March 31, 2021, we did experience slowed enrollment in the EDIT-101 clinical trial as a result of the COVID-19 pandemic. The ultimate impact of the COVID-19 pandemic is highly uncertain and we do not yet know the full extent of potential delays or impacts on our business, our ability to continue to raise additional capital, the EDIT-101 or EDIT-301 clinical trials, ongoing preclinical activities, or the global economy as a whole. In March 2020, we implemented a work from home policy, and restricted on-site activities at our facilities in Massachusetts and Colorado to certain manufacturing, laboratory and related support activities in light of the COVID-19 pandemic. Under our return to onsite work plans, we have resumed manufacturing, laboratory and related support activities at our facilities in Massachusetts and Colorado using capacity-limiting measures to comply with social distancing guidelines. As such, it is uncertain as to the full magnitude that the pandemic will have directly or indirectly on our financial condition, liquidity and future results of operations.

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 Juno Therapeutics, we have received an aggregate of $126.0 million in payments, which have primarily consisted of the initial upfront and amendment payments, development milestone payments, research funding support and certain opt-in fees. We no longer receive research funding support. As of March 31, 2021, we recorded $85.0 million of deferred revenue in relation to our collaboration with Juno Therapeutics, of which $56.7 million is classified as long-term on our condensed consolidated balance sheet. During the three months ended March 31, 2021, we recognized $5.7 million of previously deferred revenue related to our collaboration with Juno Therapeutics. Under this collaboration, we will recognize revenue upon delivery of option packages to Juno Therapeutics or upon receipt of development milestone payments. We expect that our revenue will fluctuate from quarter-to-quarter and year-to-year as a result of the timing of when we deliver such option packages or receive such milestone payments.

For additional information about our revenue recognition policy related to the Juno Therapeutics collaboration, see “—Critical Accounting Policies and Estimates—Revenue Recognition” included in our Annual Report.

For the foreseeable future we expect substantially all of our revenue will be generated from our collaboration with Juno Therapeutics, 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 and development activities, including our drug discovery efforts and preclinical studies and clinical trials under our research programs, which 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 our behalf;

●

costs of purchasing lab supplies and non-capital equipment used in our preclinical activities and in manufacturing preclinical study materials;

Table of Contents

●

consultant fees;

●

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

●

fees for acquiring and maintaining licenses under our third-party licensing agreements, including any sublicensing or success payments made to our licensors.

Research and development costs are expensed as incurred. 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 completion of preclinical studies, IND-enabling studies and natural history studies;

●

successful enrollment in, and completion of, clinical trials;

●

receipt of marketing approvals from applicable regulatory authorities;

●

establishing clinical, commercial manufacturing capabilities or making arrangements with third-party manufacturers;

●

obtaining and maintaining patent and trade secret protection and non-patent exclusivity;

●

launching commercial sales of a product, if and when approved, whether alone or in collaboration with others;

●

acceptance of a product, if and when approved, by patients, the medical community, and third-party payors;

●

effectively competing with other therapies and treatment options;

●

a continued acceptable safety profile following approval;

●

enforcing and defending intellectual property and proprietary rights and claims; and

●

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.

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 the clinical development of EDIT-101 and EDIT-301 as well as supporting 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.

Table of Contents

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 agreements 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, Net

For the three months ended March 31, 2021, other income, net consisted primarily of interest income and accretion of discounts associated with other marketable securities.

For the three months ended March 31, 2020, other income, net consisted primarily of interest income and accretion of discounts associated with marketable securities, partially offset by loss on disposal of property and equipment.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles. The preparation of our condensed 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 condensed 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 condensed consolidated financial statements prospectively from the date of change in estimates.

There have been no material changes to our critical accounting policies from those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report.

Collaboration and other research and development revenues

Collaboration and other research and development revenues increased by $0.8 million, to $6.5 million for the three months ended March 31, 2021 from $5.7 million for three months ended March 31, 2020. This increase was primarily attributable to the recognition of $5.7 million of previously deferred revenue related to Juno Therapeutics in the three months ended March 31, 2021, compared to no revenue recognized related to Juno Therapeutics for the three months ended March 31, 2020, and the recognition in the three months ended March 31, 2020 of $4.4 million of previously deferred revenue in connection with our strategic alliance with Allergan, which was terminated in August 2020, and for which no revenue was recognized in connection with such alliance in the three months ended March 31, 2021.

Research and development expenses

Research and development expenses increased by $7.3 million, to $41.9 million for the three months ended March 31, 2021 from $34.6 million for the three months ended March 31, 2020. The following table summarizes our research and development expenses for the three months ended March 31, 2021 and 2020, together with the changes in those items in dollars (in thousands) and the respective percentages of change:

For our results of operations, we have included the respective percentage of changes, unless greater than 100% or less than (100)%, in which case we have denoted such changes as not meaningful (n/m).

Table of Contents

The increase in research and development expenses for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributable to:

●

approximately $9.0 million in increased sublicense and license fees primarily related to the payment of success payments under certain of our license agreements upon the achievement of market capitalization-based milestones in the first quarter of 2021;

●

approximately $1.4 million in increased employee related expenses primarily due to an increase in the size of our workforce including the expansion of our research and development organization;

●

approximately $0.9 million in increased stock-based compensation expenses;

●

approximately $0.8 million in increased facility related expenses; and

●

approximately $0.4 million in increased other expenses.

These increases were partially offset by approximately $5.2 million in decreased external research and development expenses related to expenses incurred in the three months ended March 31, 2020 under our profit-sharing arrangement with Allergan and expenses incurred related to an in-license arrangement entered into during the first quarter of 2020 for which there were no similar expenses in the first quarter of 2021. These decreases were partially offset by increases in external research and development expenses related primarily to the clinical and manufacturing development of EDIT-101 and our other programs.

As a result of the termination of our agreements with Allergan, our research and development costs have increased, and we expect will continue to increase as we are now obligated to fund all of the costs related to developing and commercializing the LCA10 program in the United States. In addition, we will increase headcount in our clinical and development organization as a result of the transfer from Allergan to us of the Phase 1/2 clinical trial of EDIT-101 for the treatment of LCA10 as part of the termination of the arrangement with Allergan.

General and administrative expenses

General and administrative expenses increased by $3.7 million, to $21.4 million for the three months ended March 31, 2021 from $17.8 million for the three months ended March 31, 2020.The following table summarizes our general and administrative expenses for the three months ended March 31, 2021 and 2020, together with the changes in those items in dollars (in thousands) and the respective percentages of change:


	Three Months Ended
	March 31,
	2021		2020		Dollar Change		Percentage Change
Stock-based compensation expenses	$	8,238	$	3,163	$	5,075	n/m

Total general and administrative expenses	$	21,445	$	17,769	$	3,676	21	%

The increase in general and administrative expenses for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily attributable to approximately $5.1 million in increased stock-based compensation expenses related to the acceleration of vesting of certain equity awards held by our former Chief Executive Officer in connection with her separation from our company in February 2021 as well as stock-based

Table of Contents

compensation expense recorded on equity awards granted in connection with the hiring of our new Chief Executive Officer in February 2021.

The increase was partially offset by:

●

approximately $1.1 million in decreased professional service expenses primarily due to decreased use of consulting services; and

●

approximately $0.3 million in decreased intellectual property and patent related fees.

Other income, net

For the three months ended March 31, 2021, other income, net was $0.2 million, which was primarily attributable to interest income.

For the three months ended March 31, 2020, other income, net was income of $8.9 million, which was primarily attributable to the unrealized gains related to corporate equity securities, interest income and accretion of discounts associated with marketable securities.

Liquidity and Capital Resources

Sources of Liquidity

In January 2021, we completed a public offering whereby we sold 3,500,000 shares of our common stock and received net process of approximately $216.9 million. In February 2021, the underwriters in the public offering exercised their option to purchase an additional 525,000 shares, resulting in additional net proceeds to us of approximately $32.6 million. As of March 31, 2021, 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 Juno Therapeutics, our strategic alliance with Allergan, which was terminated in August 2020, and our license agreement with Beam Therapeutics. As of March 31, 2021, we had cash, cash equivalents and marketable securities of $723.2 million.

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 Juno Therapeutics. 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 March 31, 2021, our right to contingent payments under our collaboration agreement with Juno Therapeutics is our only significant committed potential external source of funds.

Cash Flows

The following table provides information regarding our cash flows for the three months ended March 31, 2021 and 2020 (in thousands):

Table of Contents

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 $49.5 million for the three months ended March 31, 2021, which primarily consisted of operating expenses that relate to our on-going preclinical and clinical activities, patent costs and license fees, 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 used in operating activities was approximately $54.1 million for the three months ended March 31, 2020, which primarily consisted of operating expenses that relate to our on-going preclinical and clinical activities, patent costs and license fees, and increased costs as a result of staffing needs due to our expanding operations. These expenses were partially offset by unrealized gains associated with our corporate equity securities.

Net Cash Used in Investing Activities

Net cash provided by investing activities was approximately $3.2 million for the three months ended March 31, 2021, primarily related to proceeds from maturities of marketable securities of $130.8 million partially offset by costs used to acquire marketable securities of $127.4 million.

Net cash provided by investing activities was approximately $46.5 million for the three months ended March 31, 2020, primarily related to proceeds from maturities of marketable securities of $115.0 million, partially offset by costs to acquire marketable securities of $66.4 million and costs to acquire property and equipment of $2.2 million.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was approximately $261.5 million for the three months ended March 31, 2021 and consisted of $249.5 million in net proceeds received from the offering of our common stock and $12.0 million in proceeds received from exercises of options for our common stock.

Net cash provided by financing activities was approximately $3.0 million for the three months ended March 31, 2020 and consisted of $3.0 million in proceeds received from exercises of options for our common stock.

Funding Requirements

We expect our expenses to increase in connection with our ongoing activities, particularly as we progress the clinical development of EDIT-101 and EDIT-301; further advance our current 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 as of March 31, 2021 and anticipated interest income will enable us to fund our operating expenses and capital expenditure requirements well into 2023. We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:

●

the scope, progress, results, and costs of drug discovery, preclinical development, laboratory testing, and clinical or natural history study trials for the product candidates we develop;

●

the costs of progressing the clinical development of EDIT-101 to treat LCA10;

●

the costs of progressing the clinical development of EDIT-301 to treat sickle cell disease;

●

the costs of IND-enabling studies for EDIT-301 to treat beta-thalassemia;

●

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

●

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

●

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

●

the success of our collaboration with Juno Therapeutics;

●

whether Juno Therapeutics exercises any of its options to extend the research program term and/or to additional research programs under our collaboration;

●

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

●

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

●

the costs of reimbursing our licensors for the prosecution and maintenance of the patent rights in-licensed by us; and

●

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. Further, our ability to continue to raise additional capital may be adversely impacted by potential worsening global economic conditions and potential disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic.

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

Table of Contents

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

During the three months ended March 31, 2021, there were no material changes to our contractual obligations and commitments described under Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report.

Off-Balance Sheet Arrangements

We did not have, during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC rules.

Effects of Inflation

Inflation would generally affect our business by increasing our cost of labor and clinical trial costs. We do not believe that inflation had a material effect on our business, financial condition or results of operations during the three months ended March 31, 2021 or 2020.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. As of March 31, 2021, we had cash and cash equivalents of $354.9 million, primarily held in money market mutual funds consisting of U.S. government-backed securities, and marketable securities of $270.4 million, primarily consisting of U.S. government-backed securities 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 March 31, 2021 were denominated in the United States dollar and we believe that we do not have any material exposure to foreign currency exchange rate risk.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be

Table of Contents

disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2021, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in litigation or other legal proceedings relating to claims arising from the ordinary course of business. There can be no assurance that any proceedings that result from these third-party actions will be resolved in our favor. In addition, if they are not resolved in our favor, there can be no assurance that the result will not have a material adverse effect on our business, financial condition, results of operations, or prospects. Certain of our intellectual property rights, including ones licensed to us under our licensing agreements, are subject to, and from time to time may be subject to, priority and validity disputes. For additional information regarding these matters, see Part I, “Item 1A. Risk Factors—Risks Related to Our Intellectual Property” in our Annual Report. Regardless of outcome, litigation or other legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

Item 1A. Risk Factors.

Information regarding risk factors affecting our business is discussed in our Annual Report under the captions “Summary of Risk Factors” and “Risk Factors.” There have been no material changes to the risk factors included in our Annual Report. Please carefully consider the information set forth in this Quarterly Report on Form 10-Q and the risk factors discussed in our Annual Report, which could materially affect our business, financial condition, results of operations, or prospects. The risks described in our Annual Report, as well as other risks and uncertainties, could materially and adversely affect our business, results of operations and financial condition, which in turn could materially and adversely affect the trading price of shares of our common stock. Additional risks not currently known to us or that we currently deem to be immaterial may also harm our business.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On January 22, 2021, we issued an aggregate of 303,599 shares of common stock to The Broad Institute, Inc. (“Broad”) in satisfaction of payment obligations in an aggregate amount of $27.5 million to Broad under the Cpf1 License Agreement and the Sponsored Research Agreement. No underwriters were involved in the foregoing issuance of securities. The securities were issued pursuant to Section 4(a)(2) under the Securities Act, relating to transactions by an issuer not involving any public offering. Prior to receiving the shares, Broad represented to us that it was acquiring the shares for its own account for investment purposes, that it had received from us and our management all of the information that it considered appropriate to evaluate whether to accept the shares, that it was capable of evaluating and understanding the risks of the investment, and that it was an accredited investor as such term is defined in Rule 501 of Regulation D promulgated under the Securities Act.
