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, which was amended in January 2021 (as amended, 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 figure 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 (as amended and restated to date, the “Cas9-I License Agreement”), Cas12a
(formerly known as Cpf1) (as amended, the “Cpf1 License Agreement”), and Cas9-II (as amended, the “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 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.
Licensor Expense Reimbursements
The Company is obligated to reimburse to Broad and Harvard for expenses incurred by each of them associated with the prosecution and maintenance of the patent rights that the Company licenses from them pursuant to the license agreement by and among the Company, Broad and Harvard, including the interference and opposition proceedings involving patents licensed to the Company under the license agreement, and other license agreements between the Company and Broad. 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 $8.2 million, $7.5 million, and $8.8 million in expense during the years ended December 31, 2024, 2023 and 2022, respectively, for such reimbursement.
Success Payments
Under the Cpf1 License Agreement and Cas9-II License Agreement, the Company is obligated to make payments (“Success Payments”) in the event the Company’s market capitalization reaches certain thresholds for a specified period of time, or in the event of a change in control of the Company, if the consideration is in excess of those thresholds. Unless the Company has undergone a change in control, Success Payments are payable by the Company in cash, shares of the Company’s 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 the event of a change in control of the Company, the Success Payments are required to be paid in cash. The Success Payments under the Cpf1 License Agreement are triggered when the Company’s market capitalization reaches certain amounts ranging from $750.0 million to $10.0 billion for a specified period of time. The Success Payments under the Cas9-II License Agreement are triggered when the Company’s market capitalization reaches certain amounts ranging from $1.0 billion to $9.0 billion for a specified period of time. In aggregate, the Company has triggered $25.0 million and $7.5 million of Success Payments under the Cpf1 License Agreement and Cas9-II License Agreement, respectively. The Company has primarily settled these amounts through the issuance of shares of its common stock.
The remaining $100.0 million and $22.5 million in Success Payments under the Cpf1 License Agreement and Cas9-II License Agreement, respectively are only payable if the market capitalization threshold are met and the Company or any affiliate or sublicensee has at least one product candidate covered by a claim of a patent right licensed to the Company that is or was subject of a clinical trial.
Other Payments
The Company pays nominal annual license fees to the institutions. If the Company sublicenses any of the patent rights to a third party, the institutions have the right to receive sublicense income, which may be offset by the licensor expense reimbursement payments that the Company has made to the institution subject to certain limitations.
Litigation
The Company is not a party to any litigation and did not have contingency reserves established for any litigation liabilities as of December 31, 2024 or 2023.

About Commitments Disclosures

Commitments and contingencies disclosures catalog a company's off-balance-sheet obligations and legal exposures — purchase commitments, guarantee arrangements, pending litigation, and regulatory proceedings. These items represent potential future cash outflows that may not appear as liabilities on the balance sheet until they become probable and estimable.

Key signals: litigation reserves and disclosed loss ranges quantify management's estimate of legal exposure, but unquantified "reasonably possible" losses often represent the larger risk. Watch for changes in language around pending cases — shifts from "remote" to "reasonably possible" or increases in estimated loss ranges signal deteriorating outcomes. Unconditional purchase obligations and take-or-pay contracts create fixed cost structures that reduce operational flexibility. Guarantee arrangements for subsidiaries or joint ventures can create cascading obligations. Compare the total commitment schedule against projected free cash flow to assess whether the company can meet its obligations without additional financing.
