ATCO Announces Completion of Arrangement for Exchange of Class II Shares by Non-Controlling Class II Share Owners (CNW Group/ATCO Ltd.)

ATCO Ltd. ("ATCO") is pleased to announce the completion of its previously announced exchange proposal to holders ("Class II Share Owners") of Class II voting shares ("Class II Shares") of ATCO other than Sentgraf Enterprises Ltd.

The Arrangement was approved by Class II Share Owners at a special meeting of Class II Share Owners held on December 10, 2025 (the "Meeting"), and by the Court of King's Bench of Alberta, which issued a final order approving the Arrangement on December 11, 2025. 

Under the terms of the Arrangement, each Class II Share held by Class II Share Owners other than Sentgraf ("Non-Controlling Class II Share Owners") was exchanged for 1.15 Class I non-voting shares ("Class I Shares") of ATCO. An aggregate of 1,015,067 Class I Shares were issued to Non-Controlling Class II Share Owners pursuant to the Arrangement.

The Class II Shares will be delisted from the Toronto Stock Exchange (the "TSX") within three trading days following the completion of the Arrangement. The Class I Shares will continue to trade on the TSX under the symbol "ACO.X".

The total number of Class II Shares represented by Class II Share Owners at the Meeting and by proxy was 11,990,639, representing 96.50 per cent of the outstanding Class II Shares.

Forward-looking information is often, but not always, identified by the use of words such as "anticipate", "plan", "estimate", "expect", "may", "will", "intend", "should", "goals", "targets", "strategy", "future", and similar expressions. In particular, forward-looking information in this news release includes, but is not limited to, references to expectations with respect to delisting the Class II Shares from the TSX and the continued listing of the Class I Shares.

Although ATCO believes that the expectations reflected in the forward-looking information are reasonable based on the information available on the date such statements are made and processes used to prepare the information, such statements are not guarantees of future performance and no assurance can be given that these expectations will prove to be correct.

Actual results could differ materially from those anticipated in this forward-looking information as a result of, among other things, the failure of ATCO to receive, in a timely manner, the necessary stock exchange approvals and other risk factors, many of which are beyond the control of ATCO. Due to the interdependencies and correlation of these factors, the impact of any one material assumption or risk on a forward-looking statement cannot be determined with certainty.
