Item 3.02. Unregistered Sales of Equity Securities.

As previously disclosed under cover of a Current

Report on Form 8-K filed by FS KKR Capital Corp. (the “Company”) on May 11, 2026 (the “Previous Report”),

the Company entered into a purchase agreement (the “Purchase Agreement”) with KKR Alternative Assets L.P., a Delaware

limited partnership (the “Purchaser”), on May 10, 2026, pursuant to which the Purchaser has agreed to purchase $150,000,000

in newly issued shares of the Company’s cumulative convertible perpetual preferred stock (the “Convertible Preferred Stock”).

The Convertible Preferred Stock will be a series of the Company’s preferred stock, par value $0.001 per share.

The closing of the purchase is subject to the

expiration of the Purchaser’s concurrently announced third-party tender offer (the “Tender Offer”) for up to $150,000,000

in aggregate amount of shares of the Company’s common stock, par value $0.001 per share, and other customary closing conditions

and the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as

amended, and is expected to occur on the 11th business day following the expiration of the Tender Offer.

The shares of Convertible Preferred Stock were

offered in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). These

securities have not and will not be registered under the Securities Act or any state securities laws and, unless so registered, may not

be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements

of the Securities Act, as applicable.

For additional information regarding the Convertible

Preferred Stock and the Purchase Agreement, see Item 1.01 of the Previous

Report. The description of the Convertible Preferred Stock and the Purchase Agreement in Item 1.01 of the Previous Report is incorporated
