Yorkville Convertible Notes

 

On March 20, 2024, the Company entered into the SEPA with Yorkville pursuant to which the Company has the right to sell to Yorkville up to $30.0 million of its shares of Company Common Stock, subject to certain limitations and conditions set forth in the SEPA, from time to time during the term of the SEPA (such transaction, the “Yorkville Transaction”). In connection with the SEPA, and subject to the conditions set forth therein, Yorkville has agreed to advance to the Company in the form of convertible promissory notes (the “Convertible Notes”) an aggregate principal amount of up to $12.5 million (the “Pre-Paid Advance”), which will be paid in three tranches. The first Pre-Paid Advance was disbursed on March 20, 2024 in the amount of $5.0 million with a fixed conversion price of $3.16. The Company received $4.6 million in cash, net of the 8% original issue discount. On May 14, 2024, the shareholders voted to approve the reservation and issuance of shares to Yorkville to exceed the Exchange Cap and the second Pre-Paid Advance was disbursed on May 16, 2024 in the amount of $4.6 million, which is the $5.0 million second Pre-Paid Advance net of $0.4 million of the 8% original issue discount, with a fixed conversion price of $2.03. The third Pre-Paid Advance was disbursed on July 17, 2024 in the principal amount of $2.3 million, which is the $2.5 million third Pre-Paid Advance net of the $0.2 million of the 8% original issue discount, with a fixed conversion price equal to 120% of the average VWAP during the three trading days immediately prior to the issuance of the note. The purchase price for the Pre-Paid Advance is 92.0% of the principal amount of the Pre-Paid Advance. Interest shall accrue on the outstanding balance of any Pre-Paid Advance at an annual rate equal to 0%, subject to an increase to 18% upon an event of default as described in the Convertible Notes. The Company paid no interest relating to the Convertible Notes.

 

Beginning on the forty-fifth (45th) day following the issuance date of the Convertible Note issued in connection with the first Pre-Paid Advance, and continuing on the same day of each successive month thereafter, (each, an “Installment Date”), the Company shall repay a portion of the outstanding balance of the Pre-Paid Advance in an amount equal to (i) $1,750,000, provided however, in respect of any Installment Date prior to the closing of the second Pre-Paid Advance, $750,000 (the “Installment Principal Amount”), plus (ii) the a payment premium of 7% of such Installment Principal Amount, and (iii) accrued and unpaid interest hereunder as of each Installment Date. The maturity date of the Convertible Notes issued in connection with each Pre-Paid Advance will be 12 months after the issuance date of such Convertible Notes. In October 2024, the Company and Yorkville agreed to amend the dates and the allocation of installment amounts to be paid pursuant to the Pre-Paid Advances, such that the outstanding balance of the Pre-Paid Advances is to be paid by February 2025. As of December 31, 2024, the Company has made aggregate installment payments on the Pre-Paid Advances in the amount of $10.2 million, of which $7.8 million was settled in cash and $2.4 million was settled in shares. Of the aggregate installment payments, $9.4 million relates to the repayment of the principal, $0.8 million relates to the 8% original issue discount and $0.6 million relates to the 7% payment premium. As of December 31, 2024, the aggregate outstanding principal balance of the Yorkville Convertible Notes is $2.1 million. As of December 31, 2024, $7.8 million of the outstanding balance of the Pre-Paid Advances has been paid in cash and $2.4 million was paid in shares of the Company issued under the SEPA. The Company still has access to the remaining funds under the SEPA. The sales of the shares of Common Stock to Yorkville under the SEPA, and the timing of any such sales, are at the Company’s option.

 

As the SEPA is an equity-linked contract that does not qualify for equity classification, any expenses incurred will be recognized in the consolidated statements of operations and comprehensive loss within borrowing related costs. For the year ended December 31, 2024, the Company recognized $1.1 million in issuance costs related to the 8% original issue discount for the SEPA.

Related Party Note

 

On March 19, 2024, the Company announced that Spectral IP received a $1.0 million investment from an affiliate of its largest shareholder for the acquisition and development of a health care related artificial intelligence intellectual property portfolio. The investment is structured as a note payable with a one-year maturity, at an interest rate of 8%, and requiring earlier prepayment if the Company spins off Spectral IP to the Company’s shareholders or if Spectral IP is sold to a third party. The holder of the Spectral IP Note exercised a number of conversion rights throughout the fourth quarter of 2024 for the full conversion of the Spectral IP Note in exchange for a total of 540,996 shares of the Company’s common stock, which represents a 5.00% discount to the closing price of the Company’s shares of Common Stock on the day prior to the date of notice of the holder’s exercise of its conversion right. 

 

Insurance Notes

 

The Company finances its director and officer liability insurance premiums over a term of less than one year. The Company has determined that the carrying amounts of all of the insurance notes approximate fair value due to the short-term nature of borrowings and current market rates of interest.

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.
