TORONTO, January 5, 2026

FAIRFAX DECLARES ANNUAL DIVIDEND

Fairfax Financial Holdings Limited (TSX: FFH and FFH.U) (“Fairfax”) announces that it has declared a dividend of US$15.00 per share on its outstanding multiple voting and subordinate voting shares, payable on January 22, 2026 to shareholders of record on January 15, 2026. Applicable Canadian withholding tax will be applied to dividends payable to non-residents of Canada.

Consistent with the practice of prior years, the amount of this dividend was determined taking into account the current operating results of Fairfax and its insurance and reinsurance companies and the current cash position at the Fairfax holding company. Consequently, as each year’s circumstances are different, this dividend should not be regarded as indicative of the amount of any future annual dividends.

Fairfax is a holding company which, through its subsidiaries, is primarily engaged in property and casualty insurance and reinsurance and the associated investment management.
