Exhibit 99.1

WhiteHorse Finance, Inc. Announces Second Quarter 2026 Earnings Results and Declares Quarterly Distribution of $0.25 Per Share

NEW YORK, August 10, 2026 /PRNewswire/ -- WhiteHorse Finance, Inc. (“WhiteHorse Finance” or the “Company”) (Nasdaq: WHF) today announced its financial results for the second quarter ended June 30, 2026. In addition, the Company’s board of directors has declared a distribution of $0.25 per share with respect to the quarter ended June 30, 2026. The distribution will be payable on October 5, 2026 to stockholders of record as of September 21, 2026.

Stuart Aronson, WhiteHorse Finance’s Chief Executive Officer, commented, “During the second quarter, we continued to execute on the priorities we outlined last quarter, including actively managing previously identified credit situations, maintaining discipline in new originations, and repurchasing shares at a discount to NAV. Our results this quarter reflected a return to net asset value growth, driven by favorable portfolio markups and the accretive impact of our share repurchase program. The majority of our portfolio remained stable, and we selectively deployed capital into new investments while keeping leverage below our target range. We remain focused on preserving liquidity, managing risk, and investing selectively. Our priority continues to be protecting shareholder value while positioning the portfolio for continued improvement over time.”

Recent Developments:

On August 10, 2026, WhiteHorse Advisers voluntarily agreed to waive and reduce the incentive fee on net investment income from its stated annual rate of 20.00% to 17.50% for the next fiscal quarter ending September 30, 2026.

Portfolio and Investment Activity

As of June 30, 2026, the fair value of WhiteHorse Finance’s investment portfolio was $569.2 million, compared with $543.0 million as of March 31, 2026. The portfolio as of June 30, 2026 consisted of 131 positions across 67 companies with a weighted average effective yield of 10.8% on income-producing debt investments.

Nearly all performing floating rate investments have interest rate floors.

During the three months ended June 30, 2026, WhiteHorse Finance made investments in three new portfolio companies for a total of $23.1 million, added a total of $2.3 million to existing portfolio companies and net fundings of $1.8 million to revolver loans.

In addition to the transactions discussed above, during the three months ended June 30, 2026, WhiteHorse Finance transferred assets comprised of two existing portfolio companies, totaling $7.8 million to STRS JV in exchange for a net investment in STRS JV of $2.3 million as well as cash proceeds of $5.5 million.

Forward-Looking Statements

This press release may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements other than statements of historical facts included in this press release may constitute forward-looking statements and are not guarantees of future performance or results and involve a number of risks and uncertainties. Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including those described from time to time in filings with the Securities and Exchange Commission. The Company undertakes no duty to update any forward-looking statement made herein. All forward-looking statements speak only as of the date of this press release.

(1) “Core net investment income” is a non-GAAP financial measure. The Company believes that core net investment income provides useful information to investors and management because it reflects the Company’s financial performance excluding (i) the net impact of costs associated with the refinancing of the Company’s indebtedness, (ii) the accrual of the capital gains incentive fee attributable to net realized and unrealized gains and losses, and (iii) excise and other income taxes related to such net realized gains and losses (net of incentive fees). The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. Additional information on core net investment income and a reconciliation of core net investment income to its most directly comparable GAAP financial measure, net investment income, are set forth in Schedule 1 hereto.

(2) Includes investments in WHF STRS Ohio Senior Loan Fund LLC (“STRS JV”), an unconsolidated joint venture.

(3) As of August 10, 2026, based on total capital raised by H.I.G. Capital and affiliates.

SCHEDULE 1

As a supplement to GAAP financial measures, the Company has provided information relating to core net investment income, which is a non-GAAP measure. This measure is provided in addition to, but not as a substitute for, net investment income determined in accordance with GAAP. The Company’s non-GAAP measures may differ from similar measures by other companies, even if similar terms are used to identify such measures. Core net investment income represents net investment income adjusted to exclude the net impact of costs associated with the refinancing of the Company’s indebtedness, the accrual of the capital gains incentive fee attributable to net realized and unrealized gains and losses, and excise or other income taxes related to such net realized gains and losses (net of incentive fees). There were no excise or other income taxes related to net realized gains and losses for the quarters ended June 30, 2026, and June 30, 2025.

The following table provides a reconciliation of net investment income to core net investment income for the three months ended June 30, 2026, and June 30, 2025 (in thousands, except per share data):
