SunLink Health Systems, Inc. provides update on Special Cash Dividend

scheduled to be paid prior to

SunLink’s proposed merger with Regional Health Properties, Inc.

ATLANTA, Georgia (July 24, 2025) – SunLink Health Systems, Inc. (NYSE American: SSY) today issued the following update with respect to its scheduled $0.10 per share special cash dividend approved by SunLink’s Board of Directors and previously announced on July 18, 2025 (the “Special Cash Dividend”).

SunLink understands that trades of SunLink common stock entered into during the period (the “due bill period”) beginning July 29, 2025 (the record date for the Special Cash Dividend) and through July 30, 2025 (the payment date for the Special Cash Dividend) will have a due bill attached for the Special Cash Dividend. Due bills obligate sellers to deliver the Special Cash Dividend to the buyer. This means that persons who purchase SunLink common stock during the due bill period are entitled to receive the Special Cash Dividend, and persons who sell the stock during the due bill period are not entitled to the Special Cash Dividend. Accordingly, if an investor wishes to receive the Special Cash Dividend, the investor will need to hold the SunLink common stock securities through and including the payment date of July 30, 2025.

The due bill obligations are settled customarily between the brokers representing the buyers and sellers of the securities. Buyers and sellers of SunLink common stock should consult with their broker before trading to ensure they understand the effect of NYSE’s due bill procedures. SunLink has no obligations for either the amount of the due bill or the processing of the due bill

SunLink Health Systems, Inc. is the parent company of subsidiaries that own and operate a pharmacy business in the Southeast. For additional information on SunLink Health Systems, Inc., please visit the Company’s website.
