2026. Following the transition, Mr. Hyzak will serve as MSC Income's Executive Chairman, and in this capacity he will

work closely with Mr. Meserve as CEO. The Board's approval of the Plan does not constitute an immediate appointment of

Mr. Meserve as CEO or Mr. Hyzak as Executive Chairman.

Mr. Meserve, age 46, currently serves as a Managing Director of MSC Income and group head of its private credit

investment team. Reference is made to the biographical information with respect to Mr. Meserve set forth under the

There is no arrangement or understanding between Mr. Meserve and any other persons pursuant to which he is being

designated as the Fund's CEO. There are no family relationships between Mr. Meserve and any director, director nominee

or executive officer of the Fund, and there are no current or proposed transactions between the Fund and Mr. Meserve or

his immediate family members that would require disclosure under Item 404(a) of Regulation S-K.

MSC Income does not and will not pay direct compensation to Mr. Meserve; his compensation is paid by MSC Adviser I,
