Explanatory Note

On May 12, 2022, Morningstar, Inc. (“Morningstar”) filed a Current Report on Form 8-K (“Original Form 8-K”) to report Bevin Desmond’s decision to depart Morningstar, originally expected to take effect in August 2022. Morningstar is filing this Form 8-K/A to provide an update on Ms. Desmond’s transition.

As previously reported on the Original Form 8-K, Bevin Desmond has decided to depart Morningstar to focus more time on her family. Ms. Desmond’s last day of employment as Morningstar’s Chief Talent and Culture Officer was January 31, 2023, at which time Ms. Desmond transitioned to contractor status. Pursuant to the terms of a Contract Services Agreement dated February 1, 2023 (the “Contract Services Agreement”), Ms. Desmond will provide certain consulting and advisory services to Morningstar during a transition period. Ms. Desmond will be paid at an hourly rate for her services and will not be entitled to equity, health coverage or other benefits. Ms. Desmond has also entered into a Separation Agreement and General Release dated February 1, 2023 (the “Separation Agreement”), pursuant to which Ms. Desmond provides a waiver and release of claim against Morningstar and receives continued vesting of her previously issued restricted stock unit and market stock unit awards.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the Contract Services Agreement and the Separation Agreement, which are filed as Exhibit 10.1 and Exhibit 10.2 respectively and incorporated by reference herein.
