All such statements are made pursuant to the “safe harbor” provisions of Canadian provincial and territorial securities laws and the U.S. Private Securities Litigation Reform Act of 1995.

Forward-looking statements are inherently subject to significant known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of ATS, or developments in ATS’ business or in its industry, to differ materially from the anticipated results, performance, achievements or developments expressed or implied by such forward-looking statements. Important risks, uncertainties and factors that could cause actual results to differ materially from expectations expressed in the forward-looking statements include, but are not limited to, the impact of regional or global conflicts; general market performance including capital market conditions and availability and cost of credit; risks related to the international trade disputes sparked by tariffs and retaliatory tariffs or other non-tariff measures, and any further escalation of such trade disputes; risks related to a recession, slowdown, and/or sustained downturn in the economy; performance of the markets that ATS serves; industry challenges in securing the supply of labor, materials and, in certain jurisdictions, energy sources such as natural gas; impact of inflation; interest rate changes; foreign currency and exchange risk; the relative weakness of the Canadian dollar; risks related to customer concentration; impact of factors such as increased pricing pressure, increased cost of energy and supplies and delays in relation thereto, and possible margin compression; the regulatory and tax environment; the emergence of new infectious diseases or any epidemic or pandemic outbreak or resurgence, and collateral consequences thereof, including the disruption of economic activity, volatility in capital and credit markets, and legislative and regulatory responses; that the ABM is not effective in accomplishing its goals; inability to successfully expand organically or through acquisition, due to an inability to grow expertise, personnel, and/or facilities at required rates or to identify, negotiate and conclude one or more acquisitions, or to raise, through debt or equity, or otherwise have available, required capital; that the market opportunities ATS anticipates do not materialize or that ATS is unable to exploit such opportunities; that the Company is unable to expand in emerging markets, or is delayed in relation thereto, due to any number of reasons, including inability to effectively execute organic or inorganic expansion plans, focus on other business priorities, or local government regulation or delays; the impacts of inflation, uncertainty caused by the supply chain dynamics, interest rate changes, international trade disputes sparked by tariffs and retaliatory tariffs or other non-tariff measures, and regional conflicts that have in the past and may in the future lead to significant price and trading fluctuations in the market price for securities in the stock markets, including the Toronto Stock Exchange and the New York Stock Exchange; energy shortages and global prices increases; the failure to realize the savings expected from reorganization activity or within the expected timelines; risk that the ultimate outcome of lawsuits, claims, and contingencies give rise to material liabilities for which no provisions have been recorded; that the Company is not successful in growing its product portfolio and/or service offering or that expected benefits are not realized; that acquisitions made are not integrated as quickly or effectively as planned or expected and, as a result, anticipated benefits and synergies are not realized; underlying trends driving customer demand will not materialize or have the impact expected; the consequence of activist initiatives on the business performance, results, or share price of the Company; the impact of analyst reports on price and trading volume of ATS’ shares; and other risks and uncertainties detailed from time to time in ATS' filings with securities regulators, including, without limitation, the risk factors described in the Registrant’s Annual information Form incorporated by reference herein. Although the Registrant has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking information and forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such information or statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such information or statements. The forward-looking statements and forward-looking information are made as of the date hereof and the Registrant disclaims any obligation to update any such factors or to publicly announce the result of any revisions to any of the forward-looking statements or forward-looking information contained herein to reflect future results, unless so required by applicable securities laws.
