Note 3 — DEBT

 

On September 11, 2023, the Company entered into a new revolving credit facility (the “Credit Facility”) with Comerica Bank (“Comerica”), replacing the prior facility with Silicon Valley Bank, that provided for maximum borrowings of $10 million. The Credit Facility may be terminated by the Company or Comerica at any time without penalty. At December 31, 2024, the available borrowings under this facility were $10 million. Any borrowings bear interest at the Secured Overnight Financing Rate plus 2.50% (or 6.99% at December 31, 2024) and would be due upon demand by Comerica. The Credit Facility is secured by all of the Company’s assets. In October 2024, the Credit Facility was amended to extend the term of the Credit Facility to November 1, 2026 and to increase the maximum borrowings to $15.0 million. The amended Credit Facility includes updated covenants requiring that the Company maintain (1) unencumbered liquid assets having a minimum value of $10.0 million in a Comerica account; (2) minimum profitability of $1 on a trailing 12-month basis; and (3) the contractual relationship with the manufacturer of the SRT-100 discussed in Note 6, Commitments and Contingencies – Manufacturing Agreement. There were no other significant changes to the terms of the Credit Facility.

 

The Company was in compliance with its financial covenants under the respective facilities as of December 31, 2024 and December 31, 2023. There were no borrowings outstanding under either facility at December 31, 2024 or December 31, 2023.

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.
