**EXPLANATORY NOTE**

​

WhiteHorse Finance, Inc., a Delaware corporation, and its consolidated subsidiaries (collectively, the “Company”, which may also be referred to as “we”, “us” or “our”) is filing this Amendment No. 1 (the “Amendment”) to our Annual Report on Form 10-K (the “Form 10-K”) for the fiscal year ended December 31, 2021, which was filed with the Securities and Exchange Commission (“SEC”) on March 4, 2022, to include the audited financial statements of WHF STRS Ohio Senior Loan Fund LLC, a joint venture created between us and State Teachers Retirement System of Ohio, or STRS JV, as of and for the year ended December 31, 2021 (as Exhibit 99.2).

​

We have determined that STRS JV has met the conditions of a significant subsidiary under Rule 1-02(w) of Regulation S-X for which we are required, pursuant to Rule 3-09 of Regulation S-X, to provide separate audited financial statements as exhibits to the Form 10-K. In accordance with Rule 3-09(b)(1), the separate audited financial statements of STRS JV are being filed as an amendment to the Form 10-K, within 90 days after the end of STRS JV’s fiscal year.

​

This Amendment also includes the filing of new Exhibits 31.1, 31.2, 32.1 and 32.2, certifications of our Chief Executive Officer and Chief Financial Officer, pursuant to Rule 13a-14(a) and (b) of the Securities Exchange Act of 1934, as amended.

​

Except as described above, no other changes have been made to the Form 10-K. This Amendment does not reflect subsequent events that may have occurred after the original filing date of the Form 10-K or modify or update in any way disclosures made in the Form 10-K, except as required to reflect the revisions discussed above. Among other things, forward-looking statements made in the Form 10-K have not been revised to reflect events that occurred or facts that became known to us after filing of the Form 10-K, and such forward-looking statements should be read in their historical context. Furthermore, this Amendment should be read in conjunction with the Form 10-K and with our subsequent filings with the SEC.
