SUN LIFE RECEIVES REGULATORY APPROVAL FOR LAUNCH OF ITS NORMAL COURSE ISSUER BID

The Office of the Superintendent of Financial Institutions and the Toronto Stock Exchange have approved Sun Life Financial Inc.'s previously announced normal course issuer bid to purchase up to 17 million of its common shares (representing approximately 2.9 per cent of the 587,055,100 common shares issued and outstanding as at Aug. 17, 2023) (the NCIB).

The NCIB will provide the company with the flexibility to acquire common shares in order to return capital to shareholders as part of its overall capital management strategy.

The NCIB will commence on Aug. 29, 2023, and continue until Aug. 28, 2024, such earlier date as the company may determine, or such date as the company completes its purchases of common shares pursuant to the NCIB. The average daily trading volume on the Toronto Stock Exchange for the six months ending July 31, 2023, was 2,210,738 common shares (the ADTV). In accordance with the TSX rules, the company may purchase up to 552,684 of its common shares on the TSX during any trading day, which represents 25 per cent of the ADTV, subject to the TSX rules permitting block purchases.

Purchases under the NCIB may be made through the facilities of the TSX, other Canadian stock exchanges and/or alternative Canadian trading platforms at prevailing market rates. Subject to regulatory approval, purchases under the NCIB may also be made by way of private agreements or share repurchase programs under issuer bid exemption orders issued by securities regulatory authorities. Any purchases made under an exemption order issued by a securities regulatory authority will generally be at a discount to the prevailing market price. The actual number of common shares purchased under the NCIB, and the timing of such purchases (if any), will be determined by the company. Any common shares purchased by the company pursuant to the NCIB will be cancelled or used in connection with certain equity settled incentive arrangements.

The company has established an automatic repurchase plan with its designated broker in order to facilitate purchases of common shares under the NCIB. Under the automatic repurchase plan, the company's designated broker may purchase common shares pursuant to the NCIB at times when the company ordinarily would not be active in the market due to its own internal trading blackout periods, insider trading rules or otherwise. Purchases made pursuant to the automatic repurchase plan, if any, will be made by the company's designated broker based upon the parameters prescribed by the TSX, applicable Canadian securities laws and the terms of the written agreement between the company and its designated broker. The automatic repurchase plan constitutes an automatic plan for purposes of applicable Canadian securities legislation and has been precleared by the TSX.
