ATCO Ltd. Normal Course Issuer Bid

CALGARY, ALBERTA--(Marketwired - March 6, 2017) - ATCO Ltd. (TSX:ACO.X)(TSX:ACO.Y) -

The Toronto Stock Exchange (the "Exchange") has accepted ATCO Ltd.'s (the "Company") Notice of Intention to Make a Normal Course Issuer Bid (the "Notice") pursuant to which the Company intends to make a normal course issuer bid ("NCIB") for certain of its outstanding Class I Non-Voting Shares ("Class I Shares") on the terms set forth in the Notice. The Company believes that, from time to time, the market price of its Class I Shares may not fully reflect the value of its business, and that purchasing its own Class I Shares represents an attractive investment opportunity and desirable use of available funds.

On February 22, 2017, 101,235,523 Class I Shares were issued and outstanding. Under the terms of the Notice and the rules of the Exchange, the Company may acquire up to 3,037,065 Class I Shares of the Company (being 3% of the Class I Shares issued and outstanding as at February 22, 2017, excluding any Class I Shares held by or on behalf of the Company on such date), during the period commencing on March 8, 2017 and ending on March 7, 2018 or such earlier date on which the Company completes its purchases of Class I Shares under the NCIB or terminates the NCIB at its option.

The aggregate number of Class I Shares that the Company may purchase under the NCIB during any trading day is subject to a maximum daily purchase limit of 44,203 Class I Shares (being 25% of the average daily trading volume for the six calendar months preceding the date of the acceptance of the Notice, which was equal to 176,813 Class I Shares) from March 8, 2017 to the termination of the NCIB. Exceptions may be made to this daily purchase limit in accordance with the "block purchase" exemptions of the Exchange policy.

Any Class I Shares purchased pursuant to the Notice will be cancelled. Class I Shares will be purchased at the market price of the Class I Shares at the time of purchase and will be purchased on behalf of the Company by a registered investment dealer through the facilities of the Exchange and any alternate trading systems through which trades of the Class I Shares may be effected under applicable securities laws. Any purchase of Class I Shares pursuant to the NCIB will be financed out of cash and working capital of the Company.

The Company purchased 460,000 Class I Shares at an average trading price of $38.79 during the most recent 12-month period preceding the date hereof pursuant to a normal course issuer bid which commenced on March 1, 2016 and expired on February 28, 2017. All of such purchases were made by means of open market transactions through the facilities of the Exchange.

A copy of the Notice may be obtained by any shareholder without charge by contacting the Corporate Secretary at the head office of the Company.

With approximately 7,000 employees and assets of $20 billion, ATCO is a diversified global corporation delivering service excellence and innovative business solutions in Structures & Logistics (workforce housing, innovative modular facilities, construction, site support services, and logistics and operations management); Electricity (electricity generation, transmission, and distribution); Pipelines & Liquids (natural gas transmission, distribution and infrastructure development, energy storage, and industrial water solutions); and Retail Energy (electricity and natural gas retail sales).
