Results of Operations and Financial Condition.

On October 15, 2025, the board of trustees (the “Board”) of FS Specialty Lending Fund (the “Fund”) declared a cash distribution. The cash distribution will be in the amount and paid on or about the payment date set forth below to shareholders of record as of the record date set forth below.

Record Date		Payment Date		Distribution Amount
October 17, 2025		October 20, 2025		$	0.6024

Certain Information About Distributions

The determination of the tax attributes of the Fund’s distributions will be made annually as of the end of the Fund’s fiscal year based upon its taxable income and distributions paid, in each case, for the full year. Therefore, a determination as to the tax attributes of the distributions made on an interim basis may not be representative of the actual tax attributes for a full year. The Fund intends to update shareholders quarterly with an estimated percentage of its distributions that resulted from taxable ordinary income. The actual tax characteristics of distributions to shareholders will be reported to shareholders annually on Form 1099-DIV. The payment of future distributions on the Fund’s common shares is subject to the discretion of the Board and applicable legal restrictions and, therefore, there can be no assurance as to the amount or timing of any such future distributions.

The Fund may fund its cash distributions to shareholders from any sources of funds legally available to it, including borrowings, net investment income from operations, capital gains proceeds from the sale of assets, non-capital gains proceeds from the sale of assets and dividends or other distributions paid to it on account of preferred and common equity investments in portfolio companies. The Fund has not established limits on the amount of funds it may use from available sources to make distributions. There can be no assurance that the Fund will be able to pay distributions at a specific rate or at all.
