First Fiscal Quarter 2022 Highlights:

• Portfolio Activity: Invested $106.9 million in six new proprietary portfolio companies and $3.9 million in existing portfolio companies. Received $96.8 million in repayments and net proceeds, primarily from the exits of five portfolio companies including a $13.4 million net realized gain in conjunction with our exit of Lignetics, Inc. Of these new investments, 65% were first lien loans which rose to 72.4% of the portfolio at cost and the weighted average yield on the debt portfolio was unchanged at 10.3%.

• Net Investment Income/ROE: NII surged 34% over last quarter to $9.2 million, or $0.27 per share, driven by higher fee income and lower net management fees. Strong earnings and portfolio appreciation combined to lift the ROE for the quarter to 15.1%.

• Net Asset Value: Increased 1.7% from September 30, 2021, to $323.9 million, or $9.44 per share, as of December 31, 2021 which brings the NAV increase over the past year to $1.83 per share or 24.0%.

• Debt Refinancing: In November 2021, we completed a private placement of 3.75% Notes due 2027 with an aggregate principal amount outstanding of $50.0 million which supported the voluntary redemption of our 5.375% Notes due 2024 with an aggregate principal amount outstanding of $38.8 million. As of the end of the quarter, our debt-to-equity ratio was a conservative 81.4% and 79% of our debt was at fixed rates.

First Fiscal Quarter 2022 Results:

Total investment income during the quarters ended December 31, 2021 and September 30, 2021 was $16.2 million and $14.4 million, respectively. The quarter over quarter increase was primarily due to a $1.6 million increase in success fees received associated with the exit of Lignetics, Inc. Interest income declined by $0.4 million quarter over quarter as the average interest-bearing investment portfolio increase of 1.4% did not offset the $0.6 million of past due interest received during the prior quarter.

Total expenses decreased by $0.5 million, quarter over quarter, primarily due to a $1.3 million decrease in the net base management fee due to the Adviser as a result of higher fee credits associated with the elevated level of originations, partially offset by a $0.6 million increase in the net incentive fee due to the Adviser.

Net investment income for the quarter ended December 31, 2021 was $9.2 million, an increase of 33.9%, as compared to the prior quarter, or $0.27 per share and covered the dividends paid of $0.195 by 137%.

The net increase in net assets resulting from operations was $12.1 million, or $0.35 per share, for the quarter ended December 31, 2021, compared to $32.7 million, or $0.98 per share, for the quarter ended September 30, 2021. The current quarter increase was driven by the increase in net investment income and $2.9 million in net realized and unrealized gains.

Subsequent Events: Subsequent to December 31, 2021, the following significant events occurred:

• Portfolio Activity:

• In January 2022, our investment in Belnick, Inc. paid off at par for net cash proceeds of $10.0 million.

• In January 2022, our investment in Keystone Acquisition Corp. paid off at par for net cash proceeds of $4.0 million.

• Distributions Declared: In January 2022, our Board of Directors declared the following monthly distributions to common stockholders for January, February, and March 2022:

Record Date	Payment Date	Distribution per Common Share
January 21, 2022	January 31, 2022	$	0.065
February 18, 2022	February 28, 2022		0.065
March 23, 2022	March 31, 2022		0.065
	Total for the Quarter	$	0.195

Comments from Gladstone Capital’s President, Bob Marcotte: “We are pleased to report that we were able to capitalize on the heightened level of deal activity last quarter and increase our first lien loans while generating a significant realized gain and maintaining our weighted average yield. The elevated deal activity also boosted fee income, which in addition to our portfolio appreciation, helped lift the Company’s ROE to 15.1% for the quarter and 27.9% for all of 2021. While 2021 ended on a high note, we expect our core lower middle market portfolio strategy and conservative balance sheet leverage to position us well to continue to grow our earnings over the balance of 2022.”
