The Toronto Stock Exchange reports that Atco Ltd.'s Class II voting shares (symbol ACO.Y) will be delisted from the TSX at the close on Dec. 15, 2025. Pursuant to an arrangement under Section 193 of the Business Corporations Act (Alberta) involving the company and Class II shareholders (other than Sentgraf Enterprises Ltd. (the unaffected Class II shareholder)), each outstanding Class II share (other than Class II shares held by the unaffected Class II shareholder) was transferred to the company for cancellation in exchange for the issuance of Class I non-voting shares of the company (symbol ACO.X).

According to the TSX, Class II shareholders (other than the unaffected Class II shareholder) will receive 1.15 Class I shares for each Class II share held. No fractional Class I shares will be issued pursuant to the arrangement. Each person otherwise entitled to a fractional interest in a Class I share will be entitled to receive a cash payment equal to such person's pro rata allocation of the net proceeds, after brokerage commissions and expenses, received by the depositary upon the sale of whole Class I shares representing an accumulation of all such fractional interests in Class I shares, without any interest thereon. To receive the consideration, Class II shareholders must return the letter of transmittal together with share certificates to TSX Trust Company (the depositary) at its principal office in Toronto.

As the record date for the company's quarterly dividend was Dec. 4, 2025, all affected Class II shareholders will receive their final dividend payment for the Class II shares on Dec. 31, 2025, in the ordinary course. For more information, see the company's management information circular dated Nov. 6, 2025, and its news release dated Dec. 11, 2025.
