The outstanding debt is related to a Loan and Security Agreement dated August 12, 2021 (the "Original Loan Agreement") entered into by the Company with Silicon Valley Bank, a California corporation ("SVB"). Pursuant to the Original Loan Agreement, the Company borrowed a term loan in the aggregate principal amount of $35.0 million to the Company (the “Original Term Loan”).
On January 6, 2023, the Company entered into a First Amendment to Loan and Security Agreement with SVB to amend our Original Loan Agreement (the "First Amendment" and with the Original Loan Agreement, collectively the "Amended Loan Agreement"). Upon entry into the Amended Loan Agreement, the Company borrowed a new term loan in the aggregate principal amount of $36.0 million (the "First Amendment Term Loan"), which was substantially used to repay in full the $35.0 million Original Term Loan outstanding under the Original Loan Agreement, and we also obtained a secured revolving credit facility in an aggregate principal amount of up to $15.0 million (the “Revolving Line”). The First Amendment also provided for a final payment fee payable to SVB of 2% of the original principal amount of the First Amendment Term Loan due upon the earlier of the First Amendment Term Loan Maturity Date, termination of the Amended Loan Agreement, acceleration by the Lender following an event of default, or prepayment of the First Amendment Term Loan.
On January 25, 2024, the Company entered into a Second Amendment to Loan and Security Agreement with Silicon Valley Bank, a division of First-Citizens Bank & Trust Company, as successor in interest to SVB ("First Citizens") to further amend our Amended Loan Agreement (the "Second Amendment" and together with the Amended Loan Agreement, collectively, the "Second Amended Loan Agreement"). The Second Amendment revised certain provisions related to financial covenants and the periods in which such covenants applied.
On November 8, 2024, the Company entered into a Third Amendment to the Loan and Security Agreement with First-Citizens to further amend our Second Amended Loan Agreement (the "Third Amendment" and together with the Second Amended Loan Agreement, collectively, the "Third Amended Loan Agreement"). Upon entry into the Third Amended Loan Agreement, we borrowed a new term loan in the aggregate principal amount of $36.0 million (the "Third Amendment Term Loan"), which was substantially used to refinance and repay in full the then-outstanding $36.0 million First Amendment Term Loan. The Company also paid a final payment fee of $0.7 million related to such prior First Amendment Term Loan. The Third Amendment set the maturity date for the Third Amendment Term Loan as September 1, 2029 (the "Third Amendment Term Loan Maturity Date"), and set the first principal repayment due date for the Third Amendment Term Loan to October 1, 2027; which date will, upon the achievement of the Performance Milestone (as defined in the Third Amendment), become October 1, 2028. Interest on the Third Amendment Term Loan will be payable monthly at a floating rate per annum equal to the greater of 4.25% and the WSJ Prime Rate minus 0.5%. The Company may elect to prepay the Third Amendment Term Loan in whole prior to the Third Amendment Term Loan Term Loan Maturity Date, subject to a prepayment fee equal to 1.5% of the original principal amount of the Third Amendment Term Loan if the loan is prepaid within 18 months following the closing of the Third Amendment. The Third Amendment revised certain provisions related to financial covenants and the periods in which such covenants apply.
The Company accounted for the Third Amended Loan Agreement as a debt modification. Accordingly, the remaining unamortized debt issuance costs related to the Second Amended Loan Agreement together with any lender fees incurred in connection with the entry of the Third Amended Loan Agreement are amortized to interest expense using the straight-line method over the new term of the loan through August 2029.
On September 25, 2025, the Company entered into a Fourth Amendment to Loan and Security Agreement with First-Citizens to further amend our Third Amended Loan Agreement (the “Fourth Amendment” and together with the Third Amended Loan Agreement, collectively, the “Fourth Amended Loan Agreement”). The Fourth Amendment revised the periods in which the financial covenants applied.
The effective interest rates for the three months ended March 31, 2026 and March 31, 2025 were 6.6% and 7.3%, respectively. The table below summarizes the future principal payments under the Fourth Amendment Loan Agreement as of March 31, 2026:

The Fourth Amended Loan Agreement includes affirmative and negative covenants applicable to the Company and certain of its foreign subsidiaries. The affirmative covenants include, among others, covenants requiring the Company to maintain its legal existence and governmental compliance, deliver certain financial reports, and maintain insurance coverage. The negative covenants include, among others, restrictions regarding transferring collateral, pledging the Company's intellectual property to other parties, engaging in mergers or acquisitions, paying dividends or making other distributions, incurring indebtedness, transacting with affiliates, and entering into certain investments, in each case subject to certain exceptions. As of March 31, 2026, the Company was in compliance with all debt covenants.
