Celestica Announces TSX Acceptance Of Its Normal Course Issuer Bid To Buy Back Up To 3.13M Shares Through November 2, 2027

Under the Bid, the Company may repurchase on the open market, at its discretion during the period commencing on November 3, 2026 and ending on the earlier of November 2, 2027 and the completion of purchases under the Bid, up to 3,132,127 common shares, representing approximately 2.5% of the "public float" (within the meaning of the rules of the TSX) as at October 20, 2026, subject to the normal terms and limitations of such bids.

Under the TSX rules, the average daily trading volume of the common shares on the TSX during the six months ended September 30, 2026 was approximately 436,307 and, accordingly, daily purchases on the TSX pursuant to the Bid will be limited to 109,076 common shares, other than purchases made pursuant to the block purchase exception. The actual number of common shares which may be purchased pursuant to the Bid and the timing of any such purchases will be determined by management of the Company, subject to applicable laws and the rules of the TSX. In accordance with the TSX rules, the maximum number of common shares which may be repurchased for cancellation under the Bid will be reduced by the number of common shares purchased by non-independent brokers for delivery pursuant to stock-based compensation plans.

Purchases are expected to be made through the facilities of the TSX, the New York Stock Exchange (the "NYSE"), other designated exchanges and/or alternative Canadian trading systems, or by such other means as may be permitted by the Ontario Securities Commission or other applicable Canadian Securities Administrators, at prevailing market prices. The Bid will be funded using existing cash resources and draws on its credit facility or other forms of available indebtedness, and any common shares repurchased by the Company under the Bid will be cancelled.
