The preliminary financial data included in this Current Report on Form 8-K has been prepared by, and is the responsibility of, the Company’s management. The Company’s independent registered public accounting firm has not audited, reviewed, examined, compiled, nor applied agreed-upon procedures with respect to the preliminary financial data. Accordingly, the Company’s independent registered public accounting firm does not express an opinion or any other form of assurance with respect thereto. The preliminary data is subject to completion of the Company’s financial closing and review procedures and is not a comprehensive statement of the Company’s financial results or valuations as of, or for the period ended, September 30, 2026. Actual results may differ materially from this preliminary data as a result of the completion of the Company’s financial closing and review procedures, final adjustments, valuation process and other developments that may arise between now and the time that the Company’s financial results for such period are finalized.

As of the date hereof:

•The preliminary estimate of our common equity net asset value as of September 30, 2026 is approximately $2.9 billion.

•The preliminary estimate of our total equity, including the perpetual preferred stock on our balance sheet as equity, as of September 30, 2026 is approximately $4.4 billion.

•The preliminary estimate of our total principal amount of debt as of September 30, 2026 is approximately $1.5 billion.

•The preliminary estimate of our total assets as of September 30, 2026 is approximately $6.0 billion.

•The preliminary estimate of our total principal amount of debt divided by our total assets is approximately 25% as of September 30, 2026.

•The preliminary estimate of our net investment income for the three months ended September 30, 2026 is approximately $76 million.

•The preliminarily estimate of our investments on non-accrual status is approximately 0.2% of the total investment portfolio at fair market value as of September 30, 2026 and approximately 1.8% of the total investment portfolio at cost as of September 30, 2026.

The information disclosed under this Item 2.02 is being “furnished” and shall not be deemed “filed” by the Company for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section, and shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

We may use words such as “anticipates,” “believes,” “expects,” “intends,” “will,” “should,” “may” and similar expressions to identify forward-looking statements. Forward-looking statements are not guarantees of future performance and should not be relied upon in making any investment decision. Such statements are based on currently available operating, financial and competitive information and are subject to various risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations.
