Convertible Note Payable
In September 2024, the Company sold and issued senior secured convertible promissory notes in aggregate principal amount of $5.0 million (the "2024 Notes") to an existing shareholder, who beneficially owns more than 5% of Fathom's
common stock, and the chairman of the Company's Board of Directors in a private placement (the "2024 Offering"). The cash proceeds to the Company from the issuance of the 2024 Note were $4.9 million after deducting the 2024 Offering expense.
Beginning on September 25, 2024 quarterly interest payments are due in cash on the principal amount at a fluctuating equal to (i) the monthly average SOFR plus (ii) 4% per annum, subject to certain adjustments, with a minimum rate of 8%. The 2024 Notes have a conversion price of $4.25 per share of common stock, representing an initial conversion premium of approximately 85% above the last reported sale price of Fathom's common stock on September 26, 2024. The 2024 Notes mature on October 1, 2026, unless repurchased or converted in accordance with their terms prior to such date. The 2024 Notes may not be converted by either purchaser into shares of common stock if such conversion would result in the purchaser and its affiliates owning an aggregate of in excess of 19.99% of the then-outstanding shares of the Company’s common stock.
In connection with the 2024 Offering, the Company also entered into Security Agreements pursuant to which the 2024 Note is secured by all existing and future assets of the Company.

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.
