| Debt | Debt On June 30, 2023, the Company entered into a loan agreement with Hercules, which provided for aggregate maximum borrowings of up to $50.0 million, including a term loan of $30.0 million, which was funded on June 30, 2023. On January 5, 2026, or the Effective Date, the Company entered into a third amendment to the loan agreement with Hercules, or the Loan Agreement. The Loan Agreement provides for five tranches of term loans in an aggregate principal amount of up to $150.0 million, consisting of (i) a term loan of $50.0 million, which was funded on the Effective Date, (ii) term loans of up to $30.0 million subject to achievement of a milestone relating to certain FDA approvals being granted, (iii) term loans of up to $20.0 million subject to achievement of a specified commercial milestone, and (iv) term loans of up to $20.0 million, plus the $30.0 million that became available to us upon achievement of a specified clinical milestone and any remaining unborrowed amounts from the earlier tranches, subject to the approval of Hercules’ investment committee. If the conditions of each term loan are met, these tranches may be borrowed in drawings of a minimum of $5.0 million each. As required by the Amended Loan Agreement, a portion of the proceeds from the Tranche 1 Advance was used to repay the outstanding principal amounts and PIK due under the second amendment to the original loan Agreement, which is approximately $31.1 million. Borrowings under the Amended Loan Agreement bear interest at an annual rate equal to the greater of (i) 9.75% or (ii) 2.75% plus the Wall Street Journal prime rate. Payments under the Amended Loan Agreement are interest only until the first principal payment is due in the first quarter of 2029, and may be deferred if the Borrowers achieve certain milestones until the scheduled maturity date on January 5, 2031. The carrying value of the Company’s outstanding debt approximates fair value, as it reflects interest rates currently available to the Company, and is classified as a Level 2 liability within the fair value hierarchy. The Company determined that the third amendment represented a modification of debt under ASC 470-50 Debt – Modification and Extinguishment. As a result, lender fees associated with the modification were capitalized as an adjustment to the carrying amount of the debt and are being amortized over the remaining term of the instrument. The Company incurred fees and transaction costs totaling $3.3 million associated with the initial term loan, which are recorded as a reduction to the carrying value of the long-term debt in the condensed consolidated balance sheets. These fees included $0.4 million of facility fees, $0.8 million of company fees, $0.7 million in warrants. In addition, the Company incurred $1.4 million of end of term charges, which are recorded as a debt discount and amortized to interest expense over the term of the loan. The Company incurred fees and transactions costs totaling $4.2 million associated with the third amendment to the Loan Agreement, including $0.3 million of facility fees. In addition, the Company incurred $3.9 million of end of term charges, which are recorded as a debt discount and amortized to interest expense over the term of the loan. The fees, transaction costs, and the end of term charges are amortized to interest expense through the maturity date using the effective interest method. The effective interest rate of the Amended Loan Agreement was 12.9% as of March 31, 2026. In 2023, the Company issued warrants to Hercules to purchase the Company’s Ordinary Shares equal to the quotient derived by dividing (i) the amount equal to (a) 2.5% times (b) the aggregate principal amount of term loan advances made and funded under the Loan Agreement by (ii) the exercise price of the warrants. Upon receipt of the first term loan in June 2023, 94,222 shares became exercisable to Hercules with a fair market value of $0.7 million. The Amended Loan Agreement includes a financial covenant requiring us to maintain cash equal to at least fifty-five percent of the outstanding debt balance during the period commencing on October 1, 2027 (subject to adjustment if certain performance milestones are met). If the Company meets the performance milestones, the minimum cash covenant will not apply if its market capitalization is at least $850.0 million. The Company was in compliance with all covenants of the Amended Loan Agreement as of March 31, 2026 and December 31, 2025. Long-term debt consisted of the following (in thousands):
Future principal payments, including End of Term Charge, are as follows (in thousands):
