ATS Announces Pricing of Initial Public Offering in the United States

6,000,000 Common Shares at a price of US$41 per share

Common Shares to begin trading on the New York Stock Exchange

CAMBRIDGE, ON, May 24, 2023 /PRNewswire/ - ATS Corporation (TSX: ATS) ("ATS" or the "Company"), an industry-leading automation solutions provider, today announced the pricing of its previously-announced public offering of the Company's Common Shares ("Common Shares") in the United States and Canada. The underwriters have agreed to purchase 6,000,000 Common Shares from the Company, at a price of US$41 per share, for aggregate gross proceeds to the Company of US$246 million.

The Common Shares are expected to begin trading on the New York Stock Exchange under the symbol "ATS" on May 25, 2023, and will continue to trade on the Toronto Stock Exchange under the symbol "ATS". The offering is expected to close on May 30, 2023, subject to customary closing conditions.

The offering is being conducted through a syndicate of underwriters led by Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC, as joint active bookrunners. TD Securities Inc. and Scotia Capital (USA) Inc. are also acting as bookrunners in connection with the offering. National Bank of Canada Financial, Inc., Cormark Securities Inc., Stifel Nicolaus Canada Inc., Commerz Markets LLC, Raymond James Ltd., RBC Capital Markets, LLC and UniCredit Capital Markets LLC are acting as co-managers.

The Company has granted the underwriters an over-allotment option, exercisable for a period of 30 days from the date of the underwriting agreement for the offering, to purchase up to an additional 900,000 Common Shares, representing up to 15% of the total number of Common Shares to be sold pursuant to the offering.

ATS expects that the net proceeds of the offering will be used for strategic opportunities, including acquisitions, as well as working capital requirements and general corporate purposes. Consistent with ATS' value creation strategy, ATS may execute on strategic opportunities, including disciplined acquisitions, if and when such opportunities arise, that drive the creation of long-term sustainable shareholder value. Pending those strategic opportunities, ATS expects to use the net proceeds to pay down amounts drawn on its C$750.0 million revolving senior secured line of credit. However, management of the Company will have discretion with respect to the actual use of the net proceeds of the offering.

In connection with the offering, ATS filed a preliminary prospectus supplement to its base shelf prospectus with the securities regulatory authorities in each of the provinces and territories of Canada, other than Québec, and will file a final prospectus supplement to its base shelf prospectus with the securities regulatory authorities in each of the provinces and territories of Canada, other than Québec.
