Changing Scene

ATS Corporation has announced that Andrew Hider will be stepping down from his role as Chief Executive Officer of the Company and from its Board of Directors (the “Board”) to pursue a new leadership opportunity outside the automation industry. The effective date for Mr. Hider’s departure from the Company is expected to be by the end of August on a date to be determined by the Board. As a result of the foregoing, Mr. Hider will be withdrawing his candidacy for election to the Board at the Company’s upcoming Annual General Meeting (“AGM”) being held on August 7th, 2025. The Company will be filing an amendment to its management information circular dated June 18th, 2025 (the “Circular”) and form of proxy to reflect this change. The Circular will otherwise remain unchanged from the version that is being mailed to shareholders of the Company and filed on SEDAR+. Ryan McLeod, the Chief Financial Officer of the Company, will assume the role of interim CEO upon Mr. Hider’s departure while the Board conducts a thorough search for a permanent replacement, consistent with the Company’s succession planning process. With nearly two decades of experience at ATS, Ryan was appointed Chief Financial Officer in 2020.
