[1] Category percentages represent the fair value of each category and subcategory as a percentage of net assets as of September 30, 2026. Our investments are generally classified as “restricted securities”, unless otherwise noted, as such term is defined under Regulation S-X Rule 6-03(f) or Securities Act Rule 144. As of September 30, 2026, we held restricted securities with an aggregate fair value of $1.4 billion, or 217.9% of our net assets. [2] Certain of the securities listed are issued by affiliate(s) of the indicated portfolio company. The majority of the securities listed, totaling $1.2 billion at fair value, are pledged as collateral to our revolving line of credit, as described further in Note 5 — Borrowings in the accompanying Notes to Consolidated Financial Statements. Additionally, under Section 55 of the Investment Company Act of 1940, as amended (the "1940 Act"), we may not acquire any non-qualifying assets unless, at the time such acquisition is made, qualifying assets represent at least 70% of our total assets. As of September 30, 2026, our investments in Pyrotek Special Effects, Inc. ("Pyrotek") and Gladstone Alternative Income Fund ("Gladstone Alternative") are considered non-qualifying assets under Section 55 of the 1940 Act. Such non-qualifying assets represent 2.5% of total assets, as of September 30, 2026. [3] Unless indicated otherwise, all cash interest rates are indexed to 30-day Secured Overnight Financing Rate ("SOFR"), which was 3.9% as of September 30, 2026.

The cash interest rate is the greater of the floor or the reference rate plus a spread. Due dates represent the contractual maturity date. [4] Unless indicated otherwise, all of our investments are valued using Level 3 inputs within the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 820, "Fair Value Measurement" ("ASC 820") fair value hierarchy. Refer to Note 3 — Investments in the accompanying Notes to Consolidated Financial Statements for additional information. [5] Unless indicated otherwise, all cash interest rates are indexed to 30-day SOFR, which was 3.7% as of March 31, 2026.
