Fourth Fiscal Quarter 2023 Highlights:

• Portfolio Activity: Invested $27.4 million in existing portfolio companies.

• Equity Issuance: Issued 4,908,211 shares of common stock at a weighted-average price of $10.01 per share through our at-the-market program, generating net proceeds of $48.3 million.

• Debt Issuance: Completed an offering of $57.0 million aggregate principal amount of 7.75% Notes due 2028.

Fourth Fiscal Quarter 2023 Results:

Total investment income increased by $0.9 million, or 4.1%, for the quarter ended September 30, 2023, compared to the prior quarter ended June 30, 2023, primarily due to a $1.5 million increase in interest income. The increase in interest income was driven by increases in both the weighted average yield and weighted average principal balance of our interest-bearing investments.

Total expenses increased by $1.6 million, quarter over quarter, primarily due to a $1.7 million increase in the net base management fee, driven mainly by a decrease in portfolio company fee credits from new deal originations quarter over quarter.

Net investment income for the quarter ended September 30, 2023 was $11.0 million, or $0.28 per share, and covered distributions paid of $0.2675 by 105%.

The net increase in net assets resulting from operations was $13.1 million, or $0.33 per share, for the quarter ended September 30, 2023, compared to $11.9 million, or $0.32 per share, for the quarter ended June 30, 2023. The current quarter increase was primarily driven by $2.4 million of net unrealized appreciation recognized during the quarter.

Fiscal Year Ended 2023 Results:

Total investment income during the years ended September 30, 2023 and 2022 was $86.4 million and $63.2 million, respectively. The year over year increase was primarily due to a $29.0 million increase in interest income, driven by an increase in the weighted average principal balance of our interest-bearing investment portfolio of $109.5 million, or 21.2%, year over year, and an increase in the weighted average yield from 10.4% during the year ended September 30, 2022 to 13.3% during the year ended September 30, 2023.

Expenses, net of any non-contractual, unconditional and irrevocable credits to fees from the Adviser, increased $14.5 million, or 47.1%, for the year ended September 30, 2023, as compared to the prior year. This increase was primarily due to a $7.9 million increase in interest expense on borrowings and a $3.2 million increase in the net incentive fee.

Net investment income for the year ended September 30, 2023 was $41.0 million, an increase of 27.1%, as compared to the prior year, or $1.10 per share.

The net increase in net assets resulting from operations was $42.7 million, or $1.14 per share, for the year ended September 30, 2023, compared to $19.9 million, or $0.58 per share, for the year ended September 30, 2022. The current year increase was driven by net investment income of $41.0 million and $12.7 million in net realized gains, partially offset by $11.0 million in net unrealized depreciation.

Comments from Gladstone Capital’s President, Bob Marcotte: “While net originations moderated last quarter negatively impacting fee income, the underlying portfolio continued to perform well generating an 8% increase in net interest income and ROE of 13.7% for the period. These results capped a strong fiscal 2023 for GLAD where we achieved 9% asset growth and 27% NII growth which supported the 22% increase in the common distribution rate and NAV growth of 3.4%. We ended fiscal 2023 with a conservate leverage profile and ample borrowing capacity to capitalize on the growing private credit opportunity across the lower middle market and grow our earning assets, net interest income and shareholder distributions in the coming quarters.”
