Innovatus Loan Agreement

On October 31, 2022, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Innovatus Life Sciences Fund I, LP, as the collateral agent and a lender, allowing us to borrow, subject to our achievement of certain milestones, up to a total of $50.0 million in a series of term loans (collectively, the “Term Loans”). We had $50.0 million in outstanding Term Loans under the Loan Agreement as of December 31, 2025. The Loan Agreement initially required interest only payments through November 2027, followed by three monthly principal and interest payments, of which a principal payment of $16.7 million each is due in December 2027 and two principal payments of $16.7 million each are due in January 2028. As of December 31, 2025, a final payment of $2.3 million, equal to 4.5% of the original borrowed principal, was due in January 2028. The Term Loans bear interest at a floating rate per annum equal to the sum of (a) the greater of (i) the prime rate and (ii) 5.50%; plus (b) 2.65%. The Term Loans are secured by substantially all of our personal property. A performance covenant took effect upon the third tranche funding, requiring that we achieve 50% of the trailing twelve months revenue target set in the Board-approved revenue plan in effect for such period. The Loan Agreement requires the payment of certain penalties if the Term Loans are paid off prior to maturity for any reason, including pursuant to an acceleration clause, and includes various restrictive covenants, including a restriction on the payment of dividends or making other distributions or payments on our capital stock, subject to limited exceptions. We were in compliance with these covenants as of December 31, 2025.

In connection with the Loan Agreement, we recorded $1.1 million of debt issuance costs and discounts as a reduction of long-term debt.

On January 9, 2026, we entered into an Amendment to our existing Loan Agreement. See Note 13 “Subsequent Events” for further information.

About Debt Disclosures

Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.

Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
