HRZN entered into an agreement pursuant to which Monroe Capital Corporation (“MRCC”; NASDAQ: MRCC) would merge with and into HRZN, subject to the receipt of certain shareholder approvals and the satisfaction of other closing conditions

“We produced a solid third quarter by increasing our net asset value and achieving strong NII, as we moved toward completing our merger with MRCC,” said Mike Balkin, Chief Executive Officer of Horizon. “In the quarter, we originated a modest number of new loans and acquired the portfolio of a co-lender, which was accretive to our net asset value per share. We also achieved positive outcomes with respect to two stressed investments, which is a testament to our ability to work with our portfolio companies to achieve positive solutions in downside situations.”

“We also strengthened our balance sheet in the quarter, completing a $40 million convertible notes offering and accretively raising capital through our ATM program,” added Mr. Balkin. “Moving forward, we remain excited to complete the merger with MRCC, which along with our active relationship with Monroe Capital will better position us to win larger venture lending transactions and grow our portfolio.”

Third Quarter 2025 Operating Results

Total investment income for the quarter ended September 30, 2025 was $26.3 million, compared to $24.6 million for the quarter ended September 30, 2024, primarily due to higher fee and interest income on investments from the debt investment portfolio.

The Company’s dollar-weighted annualized yield on average debt investments for the quarter ended September 30, 2025 and 2024 was 18.6% and 15.9%, respectively. The Company calculates the dollar-weighted annualized yield on average debt investments for any period measured as (1) total investment income (excluding dividend income) during the period divided by (2) the average of the fair value of debt investments outstanding on (a) the last day of the calendar month immediately preceding the first day of the period and (b) the last day of each calendar month during the period. The dollar-weighted annualized yield on average debt investments is higher than what investors will realize because it does not reflect expenses or any sales load paid by investors. The dollar-weighted annualized yield on average debt investments for the three months ended September 30, 2025 as compared to the three months ended September 30, 2024 increased primarily due to the recognition and capitalization of accrued, but previously unrecorded interest income in connection with the settlement of two debt investments previously on non-accrual status.

Total expenses for the quarter ended September 30, 2025 were $12.0 million, compared to $12.4 million for the quarter ended September 30, 2024. The decrease was primarily due to a $0.2 million decrease in base management fee due to a lower average weighted size of the portfolio in the quarter.

Net investment income for the quarter ended September 30, 2025 was $14.0 million, or $0.32 per basic share, compared to $11.8 million, or $0.32 per basic share, for the quarter ended September 30, 2024.

For the quarter ended September 30, 2025, net realized loss on investments was $22.5 million, or $0.52 per basic share, compared to a net realized loss on investments of $33.9 million, or $0.93 per basic share, for the quarter ended September 30, 2024. For the quarter ended September 30, 2025, net realized loss on extinguishment of debt was $1.3 million, or $0.03 per basic share.

For the quarter ended September 30, 2025, net unrealized appreciation on investments was $40.5 million, or $0.94 per basic share, compared to net unrealized appreciation on investments of $29.3 million, or $0.80 per basic share, for the prior-year period.

As of September 30, 2025, June 30, 2025 and December 31, 2024, Horizon’s loan portfolio had weighted average credit ratings of 2.9, 3.0 and 3.1, respectively, with 4 being the highest credit quality rating and 3 being the rating for a standard level of risk.

A rating of 1 represents deteriorating credit quality and high degree of risk of loss of principal.

As of September 30, 2025, there were four debt investments with an internal credit rating of 1, with an aggregate cost of $61.3 million and an aggregate fair value of $29.3 million.

Monthly Distributions Declared in Fourth Quarter 2025

On October 22, 2025, the Company’s Board declared monthly distributions of $0.11 per share payable in each of January, February and March 2026. The following tables show these monthly distributions, which total $0.33 per share:

Monthly Distributions

Ex-Dividend Date	Record Date	Payment Date	Amount per Share
December 17, 2025	December 17, 2025	January 15, 2026	$	0.11
January 16, 2026	January 16, 2026	February 13, 2026	$	0.11
February 17, 2026	February 17, 2026	March 13, 2026	$	0.11
		Total:	$	0.33

After paying distributions of $0.33 per share and earning net investment income of $0.32 per share for the quarter, the Company’s undistributed spillover income as of September 30, 2025 was $0.93 per share. Spillover income includes any ordinary income and net capital gains from the preceding tax years that were not distributed during such tax years.

Horizon’s Board sets the level of distributions for each quarter based on its results of operations, spillover income and longer-term outlook. The Board declared monthly distributions of $0.11 per share on October 22, 2025 and payable in the first quarter of 2026 based upon the Board’s consideration of the third quarter results of the Company and the spillover income of the Company. The Board will determine the next amount of distributions in February 2026, when it will have the Company’s operating results for the fourth quarter of 2025, its spillover income at December 31, 2025 and have more clarity on its planned operating results for fiscal year 2026, which will take into account the impact of its anticipated merger with Monroe Capital Corporation. This could result in a declaration of distributions lower than the distribution level declared in the fourth quarter of 2025.

When declaring distributions, Horizon’s board of directors reviews estimates of taxable income available for distribution, which may differ from consolidated net income under generally accepted accounting principles due to (i) changes in unrealized appreciation and depreciation, (ii) temporary and permanent differences in income and expense recognition, and (iii) the amount of spillover income carried over from a given year for distribution in the following year. The final determination of taxable income for each tax year, as well as the tax attributes for distributions in such tax year, will be made after the close of the tax year.
