Fort Mill, SC, March 2, 2021 – Domtar Corporation (NYSE: UFS) (TSX: UFS) today announced that it has entered into an accelerated share repurchase (“ASR”) agreement with JPMorgan Chase Bank, N.A. to repurchase $200 million of its common stock with available cash on hand.

Under the ASR agreement, the Company will pay $200 million in exchange for an initial delivery of 4,430,906 shares.
