ATS ANNOUNCES CEO DEPARTURE

Andrew Hider will step down from his role as chief executive officer of ATS Corp. and from its board of directors to pursue a new leadership opportunity outside of 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 coming annual general meeting being held on Aug. 7, 2025. The company will be filing an amendment to its management information circular dated June 18, 2025, 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 chief executive officer 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, Mr. McLeod was appointed chief financial officer in 2020.

"Since joining us over eight years ago, Andrew has led ATS through a period of substantial growth, both organic and through acquisition," said David McAusland, chairman of the board of directors. "In addition to introducing the ATS business model, which is now deeply rooted in our management culture globally, he has built a strong, skilled senior leadership team capable of moving our business forward until a new CEO is appointed."

"We sincerely want to thank Andrew for his leadership and commitment," said Mike Martino, who is a current director and is anticipated to be elected as the new board chair following the company's AGM on Aug. 7, 2025. "With his passion and determination, he has guided the company through times of change while remaining focused on growth and strengthening the business, putting ATS in a solid position for the future."

Reflecting on his time with the company, Mr. Hider shared: "Leading ATS has been a privilege, and I'm proud of the progress this company has made. I'm grateful to have worked with, and learned from, an outstanding leadership group and ATS's incredible global team members. I look forward to continuing to watch the company grow and prosper."

The company notes that its outlook for the current fiscal quarter and fiscal year remains unchanged.
