Dear Fellow Shareholder:

Pediatrix Medical Group, Inc. ("Pediatrix" or the "Company") will hold its 2026 Annual Meeting of Shareholders (the "Annual Meeting") on May 7, 2026. At this time, you should have access to a copy of our definitive proxy statement (the "Proxy Statement") for the Annual Meeting. As described in the Proxy Statement, the Board of Directors (the "Board") of the Company unanimously recommends that you vote "FOR" each of the Company's nine director nominees.

Institutional Shareholder Services Inc. ("ISS") and Glass, Lewis & Co. LLC ("Glass Lewis") have each recommended a vote "FOR" eight of the Company's director nominees and a vote "FOR" each of the other proposals in the Proxy Statement, but have recommended a vote against the re-election of John M. Starcher, Jr. as an independent director solely because he attended less than 75% of the meetings of the Board and the Compensation and Talent Committee during 2025. ISS and Glass Lewis have each recommended "FOR" Mr. Starcher in each of the prior years he has been nominated as a Pediatrix director.

Mr. Starcher is a highly engaged and respected member of our Board who brings critical healthcare industry experience and perspective:

During Mr. Starcher's almost six-year tenure on the Board, he has devoted enormous time, talent and commitment to the success of Pediatrix, attending approximately 87% of Board meetings, 90% of committee meetings on which he served, and 88% of combined Board and committee meetings.

During 2025, Mr. Starcher attended 73% of the combined Board and Compensation and Talent Committee meetings, missing only one Board meeting and two Compensation and Talent Committee meetings. Two of these meetings were held on the same day and reflect a single unavoidable scheduling conflict. Mr. Starcher informed the Board and Compensation and Talent Committee of this conflict in advance, reviewed the applicable Board and committee materials and provided detailed feedback to the Board in advance of the meetings.

We do not expect Mr. Starcher's attendance to be an issue in the future (Mr. Starcher has attended all Board and applicable committee meetings in 2026), and management and the Board remain strongly supportive of his candidacy and the value he brings to Pediatrix.

In light of Mr. Starcher's extensive leadership experience, deep industry expertise and consistent record of engagement and attendance, we strongly urge you to vote "FOR" Mr. Starcher and "FOR" each of the Company's other director nominees.

Thank you for your support of Pediatrix Medical Group, Inc.

Sincerely,

Mark S. Ordan
