SVB Term Loan

In January 2021, the Company entered into the Loan Agreement with SVB for a term loan in three tranches. In 2021, the Company drew down on two of the tranches in the aggregate principal amount of $15.0 million. On May 12, 2023, the Company repaid all outstanding principal and accrued and unpaid interest on the funds received under the Loan Agreement and all other outstanding obligations with respect to the funds received under the Loan Agreement and made a final payment.

In connection with the Loan Agreement, the Company entered into a Success Fee Agreement (the Success Fee Agreement) with SVB in January 2021. In accordance with the Success Fee Agreement, the Company agreed to pay to SVB an amount equal to (a) the quotient of (i) the aggregate original principal amount of all Term Loan Advances made by SVB to the Company divided by (ii) $5 million, multiplied by (b) $125,000 (the Success Fee), upon the closing of a success fee event (the Success Fee Event) and, in the event of an IPO, within five business days of closing such IPO. In connection with the Company’s IPO, it became obligated to pay SVB the Success Fee.

On March 5, 2024, the Company paid $0.4 million for the success fee under the Success Fee Agreement. As of December 31, 2025 and 2024, the Company has no outstanding obligations in connection with the Loan Agreement with SVB.

In connection with the Conversion Event, the Company assumed an unsecured promissory note held by Biovire (the Biovire Note) with an outstanding principal balance of $3.0 million. The Company determined that the carrying amount of the Biovire Note represented its fair value. The Biovire Note is due and payable on February 28, 2028 (Maturity Date) and accrues interest at the lesser of (i) the daily term SOFR rate plus 2.60% and (ii) 25.0%, or the highest rate permitted by applicable law, and is payable monthly. The Company has the ability to repay the Biovire Note in full prior to the Maturity Date without penalty.
