You should carefully consider the risks described below and all other information contained in this Quarterly Report on Form 10-Q, including MSC Income’s interim consolidated financial statements and the related notes thereto, before making a decision to purchase MSC Income’s securities. The risks and uncertainties described below are not the only ones facing the Fund. Additional risks and uncertainties not currently known or currently deemed to be immaterial also may have a material adverse effect on the Fund’s business, financial condition and/or operating results, as well as the market price of MSC Income’s securities.

In addition to the other information set forth in this report, you should carefully consider the risk factors described in Item 1A. Risk Factors in MSC Income’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the SEC on March 20, 2025 and in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 filed with the SEC on May 13, 2025, which could materially affect the business, financial condition and/or operating results.

Waivers, deferrals and reductions of fees and costs can temporarily result in higher returns to investors than they would otherwise receive if full fees and costs were charged.

The Adviser is permitted, in its sole discretion, to waive, defer or reduce, in whole or in part, temporarily or permanently, some of the fees or costs otherwise due from MSC Income to the Adviser under the Advisory Agreement. While this activity can be seen as friendly to investors, waivers, deferrals and reductions of fees and costs result in higher returns to investors than such investors would receive if full fees and costs were charged. Any distributions MSC Income pays to its stockholders from sources other than cash flow from operations or relying on fee waivers, deferrals or reductions, if any, from the Adviser are not based on MSC Income’s investment performance, and can be sustained only if MSC Income achieves positive investment performance in future periods and/or the Adviser continues to waive, defer or reduce such fees or costs, if any. There is no guarantee that any waivers, deferrals or reductions will occur in the future, and any waivers, deferrals and reductions are entirely at the discretion of the Adviser.
