SUN LIFE CAUTIONS SHAREHOLDERS REGARDING OCEHAN LLC'S BELOW-MARKET BID FOR SHARES

Sun Life Financial Inc. has been notified that Ocehan LLC has made an unsolicited mini-tender offer to purchase up to 100,000 common shares of Sun Life.

Sun Life is not associated with Ocehan and does not recommend or endorse acceptance of Ocehan's unsolicited offer. Shareholders are not required to sell their shares to Ocehan.

Sun Life cautions that Ocehan's mini-tender offer has been made at a price that is significantly lower than recent market prices for Sun Life common shares. This offer represents a discount of 24.95 per cent and 24.38 per cent, respectively, to the closing prices of Sun Life's common shares on the Toronto Stock Exchange on May 25, 2026, and the New York Stock Exchange on May 22, 2026, the last trading day before the mini-tender offer was commenced.

About mini-tender offers

Securities administrators in Canada and the United States recommend that investors exercise caution with mini-tender offers. Mini-tender offers are designed to avoid disclosure and procedural requirements applicable to most bids under applicable Canadian and U.S. securities laws. Canadian Securities Administrators (CSA) and the U.S. Securities and Exchange Commission (SEC) have expressed serious concerns about mini-tender offers, including the possibility that investors might tender to such offers without understanding the offer price relative to the actual market price of their securities.

According to Ocehan's offer documents, Sun Life shareholders who have already tendered their shares can withdraw their shares within 21 days in accordance with the procedures set forth in the offer documents.

Shareholders should carefully review the Ocehan offer documents, consult with their Sun Life advisor or investment adviser to discuss any offer they may receive and review all options they have for their investment in Sun Life shares.
