[8-K] Horizon Technology Finance Corporation Reports Material Event

Rhea-AI Filing Summary

Horizon Technology Finance Corporation sold $40,000,000 aggregate principal of 5.50% Convertible Notes due 2030 under an effective shelf, receiving approximately $36.6 million in net proceeds before expenses. Interest is 5.50% per annum, payable monthly beginning September 30, 2025. The notes mature September 4, 2030 and are unsecured obligations ranking pari passu with unsecured debt, junior to secured debt and structurally junior to subsidiary obligations. The company may redeem the notes at par on or after March 4, 2025. Holders may convert beginning October 4, 2025, with the conversion price equal to the greater of a five-day VWAP or the most recently reported net asset value per share; conversions are subject to a 4.99% aggregate ownership limit for certain adviser-related holders. The filing incorporates the Note Purchase Agreement as an exhibit.

Positive

• $36.6 million in net proceeds provides immediate corporate liquidity
• 5.50% coupon is a defined and relatively modest fixed interest cost
• Conversion price floor tied to NAV can protect against conversion at depressed market prices
• Issuer redemption option at par gives the company flexibility to manage the debt

Negative

• Unsecured ranking means these notes are effectively junior to secured creditors and subordinate to subsidiary obligations
• Potential equity dilution from conversions beginning October 4, 2025
• Net proceeds ($36.6M) are less than principal amount issued ($40M) after expenses
• Conversion ownership cap (4.99%) may complicate large conversions and secondary market dynamics

Insights

Debt Capital Markets Analyst

TL;DR: Company raised $36.6M net via 5.50% convertibles, adding flexible capital but creating potential equity dilution.

This transaction provides near-term liquidity at a modest fixed coupon while preserving optionality through conversion features linked to either market price or NAV, which can protect conversion economics if the stock is volatile. Monthly interest payments create steady cash outflow obligations. The notes are unsecured and will rank behind secured creditors, which affects recovery priority in stress scenarios. The 4.99% ownership cap limits large single-party conversions, which may reduce block conversion risk but could complicate conversion timing.

Corporate Governance & Capital Structure Expert

TL;DR: The issuance alters capital structure by adding junior unsecured debt with conversion mechanics tied to VWAP or NAV, impacting leverage and potential dilution.

The convertible's conversion formula referencing the greater of VWAP or reported NAV can preserve NAV dilution relative to market-driven conversions. Redemption at par provides the issuer optionality to retire the notes if cash becomes available. Absence of a sinking fund is typical but means repayment depends on issuer cash generation or refinancing.

Section 1	Registrant’s Business and Operations
Item 1.01	Entry into a Material Definitive Agreement

Convertible Notes

On September 4, 2025, Horizon Technology Finance Corporation (the “Company”) entered into a note purchase agreement (the “Note Purchase Agreement”), by and among the Company and each purchaser named therein (the “Purchasers”), in connection with the issuance and sale of $40,000,000 aggregate principal amount of the Company’s 5.50% Convertible Notes due 2030 (the “Convertible Notes”), pursuant to an effective shelf registration statement on Form N-2 (File No. 333-278396), as amended, which was declared effective on June 20, 2024. The Company received net proceeds (before expenses) from the sale of the Convertible Notes of approximately $36.6 million. The Company intends to use the net proceeds from this offering for general corporate purposes, which may include paying down existing indebtedness.

The Convertible Notes mature on September 4, 2030 (the “Maturity Date”), unless earlier converted or repurchased in accordance with their terms. The Convertible Notes bear interest at a rate of 5.50% per annum, payable monthly in arrears on the last day of each calendar month, beginning on September 30, 2025.

The Convertible Notes will be direct unsecured obligations of the Company and will rank (i) equal in right of payment to the Company’s existing and future unsecured indebtedness that is not subordinated in right of payment to the Convertible Notes; (ii) senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Convertible Notes; (iii) effectively junior in right of payment to the Company’s existing and future secured indebtedness (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness; and (iv) structurally junior to all existing and future indebtedness and other obligations of any of the Company’s subsidiaries. No sinking fund is provided for the Convertible Notes.

At any time on or after March 4, 2025, at the Company’s sole option, the Company may redeem, from time to time, the Convertible Notes in whole or in part, out of funds legally available for such redemption, at 100% of the principal amount prepaid plus accrued but unpaid interest to but excluding the date of prepayment.

Each holder of a Convertible Note shall have the right, at such holder’s option, to convert all or a portion of any such Convertible Note, on or after October 4, 2025, the date that is thirty (30) days after the issuance of the Convertible Notes, and prior to the close of business on the business day immediately preceding the Maturity Date, once or more times per calendar month, into such number of shares of common stock (“Shares”) of the Company equal to the principal balance of the Convertible Note being converted on the conversion date plus the accrued but unpaid interest on the Convertible Note as of the conversion date, divided by the Conversion Price (defined below). The “Conversion Price” is the greater of (i) volume-weighted average closing sale price for the five trading days immediately prior to the relevant conversion date and (ii) the Company’s most recently reported net asset value per Share as of the business day immediately prior to the date of the notice of such exercise.

No holder of Convertible Notes may exercise its conversion right if upon conversion the holder would receive Shares that would cause funds and accounts managed by the investment adviser to such funds and accounts and any person controlled by the parent company of such investment adviser to beneficially own in the aggregate more than 4.99% of the Shares outstanding at such time.

The foregoing description of the Convertible Notes is a summary of the material terms of the Convertible Notes, does not purport to be complete summary and is qualified in its entirety by reference to the full text of the Note Purchase Agreement filed herewith as Exhibit 10.1 and incorporated by reference herein.
