| Debt | Debt Liability for the Sale of Future Revenues On October 3, 2024, the Company entered into the DRI Agreement under which it sold, transferred, assigned, and conveyed to DRI certain future license fees and other payments (the “Purchased Receivables”) owed to the Company by Vertex under the terms of the Vertex License Agreement in exchange for an upfront cash payment by DRI to the Company of $57.0 million. Under the DRI Agreement, DRI is purchasing up to 100% of certain future fixed and sales-based annual license fees that the Company is entitled to receive under the Vertex License Agreement, which fees range from $5.0 million to $40.0 million per year, including increases based on sales. In addition, DRI is purchasing a mid-double-digit percentage of a $50.0 million contingent upfront payment that the Company may receive under the Vertex License Agreement. All amounts above will be adjusted to exclude payments that the Company owes to Broad and Harvard under the Cas9-I License Agreement, as defined in Note 7, Commitments and Contingencies. The Company has retained rights to certain portions of certain sales-based annual license fees and the contingent upfront payment that may become due under the Vertex License Agreement, and the amounts that correspond to its licensor obligations. In accordance with Accounting Standards Codification (“ASC”) Topic 470, Borrower’s Accounting for Debt Modification, the Company has accounted for the transaction as debt. The gross proceeds of $57.0 million were recorded as a liability for the sale of future revenues, net of transaction costs of $1.8 million, which will be amortized over the estimated life of the arrangement using the effective interest method. The Company estimates the effective interest rate used to record non-cash interest expense under the Purchase and Sale Agreement based on the estimate of future revenue payments to be made to DRI. As of March 31, 2026, the estimated effective interest rate under the agreement was 7.7%. Over the life of the arrangement, the actual effective interest rate will be affected by the amount and timing of the payments made to DRI and changes in the Company's revenue forecasts. At each reporting date, the Company will reassess its estimate of total future payments to be made to DRI, and prospectively adjust the effective interest rate and amortization of the liability as necessary. The following table presents the changes in the liability related to the sale of future revenues under the Purchase and Sale Agreement with DRI as of March 31, 2026 (in thousands):
