Dear Fellow Stockholder:

You are hereby invited to attend the 2026 Annual Meeting of Stockholders, which will be held at 9:00 a.m. local time on Wednesday, March 11, 2026, at the Company’s corporate headquarters, 3920 Arkwright Road, Suite 200, Macon, Georgia 31210.

The accompanying Notice of the Annual Meeting, Notice of Internet Availability of Proxy Materials and Proxy Statement provide important information about the meeting and will serve as your guide to the business to be conducted at the meeting.

The internet will be the primary means by which we furnish proxy materials to our stockholders. We will send stockholders a notice with instructions on how to access these materials. The notice will also include information about obtaining paper copies of our proxy materials if stockholders choose to do so. This process lowers costs and saves paper, adding convenience for stockholders and contributing to our sustainability efforts.

Your vote is very important to us. We urge you to read the accompanying materials regarding the matters to be voted on at the meeting.

You may vote either by submitting your proxy via smartphone/tablet, online or, if you receive a paper proxy card in the mail, by mailing the completed proxy card. If you vote before the meeting but later decide to attend the meeting in person, you may still vote in person at the meeting.

Thank you for your continued support.


			Sincerely,

			/s/ John F. Wyskiel
