The carrying amount of debt approximates fair value due to its variable interest rate.

In December 2021, the Company entered into a non-revolving loan and security agreement (the Loan Agreement) with Oxford Finance. The Loan Agreement has a borrowing capacity of up to $50.0 million, of which $5.0 million was funded in December 2021, and the remaining credit facility was scheduled to expire in December 2022. In November 2022, the Company entered into an amendment of the Loan Agreement. Among other changes, the amendment extended the scheduled expiration of the Loan Agreement to December 2023 and modified the reference rate from the London Interbank Offered Rate (LIBOR) to the Secured Overnight Financial Rate (SOFR). In conjunction with the amendment, the Company borrowed an additional $20.0 million from the Loan Agreement. In December 2023, the Company borrowed the remaining $25.0 million from the Loan Agreement. As of June 30, 2024, the Company’s outstanding borrowing under the Loan Agreement was $50.0 million.

In March 2023, upon achievement of a clinical data milestone, the Company elected to exercise a borrower option to extend the maturity of the outstanding loan by 12 months, from December 2026 to December 2027. The end date of the interest-only payment period was also extended by 12 months, from December 2025 to December 2026. The Company is permitted to prepay the loan, subject to certain conditions. Upon the maturity date or prepayment of the loan, the Company is required to pay an exit fee equal to 7% of the aggregate principal amount of the loan.

The variable interest rate on the drawn amount is adjusted SOFR plus 825 basis points, subject to a per annum floor rate of 8.25%. The Loan Agreement contains a subjective acceleration clause in the case of an event of default. If such a matter occurs and is continuing, the lender may legally demand the outstanding principal and interest immediately due and payable. There are no financial covenants associated with the Loan Agreement and the loan is secured by the Company’s assets. The Loan Agreement is available for working capital, capital expenditures, and other general corporate purposes.
