The Second Amendment to the Loan and Security Agreement introduced significant changes to the debt structure and covenants:

Outlook, Risks, and Collateral
The Company has granted a first-priority security interest in substantially all of its property, including intellectual property, as collateral for the loan. Future borrowing of the remaining $200.0 million in available tranches is contingent upon the achievement of specified clinical, regulatory, and commercial milestones or the discretionary approval of the Lenders' investment committee. The filing does not provide specific revenue, profit, or cash flow metrics for the period, as this is a transactional report rather than a periodic financial statement.
Key Facts for Investor Verification
- Verify the Company's current market capitalization to determine if the 40% cash covenant is currently active.
- Monitor progress on the clinical, regulatory, and commercial milestones required to access the remaining $125.0 million in tranche funding.
- Review the full text of the Second Amendment (to be filed as an exhibit to the Q2 2026 10-Q) for detailed terms regarding the discretionary $75.0 million tranche.
- Assess the impact of the floating interest rate (Prime + 2.45%) on future interest expense given the $200.0 million outstanding balance.
