**Gladstone Capital Corporation Announces Proposed Convertible Notes Offering** 

McLean, VA, September 8, 2025: <u>Gladstone Capital Corporation</u> (Nasdaq: GLAD) (the "Company") today announced the commencement of a registered public offering of $110 million aggregate principal amount of unsecured convertible notes due 2030 (the "Notes"). In addition, the Company expects to grant the underwriter of the Notes an option to purchase up to an additional $16.5 million in aggregate principal amount of the Notes.

The Notes will be unsecured obligations of the Company and will pay interest semi-annually in arrears and will mature in 2030, unless earlier converted, redeemed or repurchased. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock, at the Company's election. The interest rate, initial conversion rate, redemption or repurchase rights and other terms of the Notes will be determined at the time of pricing of the offering.

The Company intends to use the net proceeds from this offering to repay a portion of the outstanding indebtedness under its revolving credit facility and for other general corporate purposes.
