WSP announces private offering of US$1.5 billion aggregate principal amount of senior unsecured notes

MONTREAL, March 11, 2026 (GLOBE NEWSWIRE) — WSP Global Inc. (TSX: WSP) (“WSP” or the “Corporation”) announced today that it has priced a private offering (the “Offering”) of US$650 million aggregate principal amount of 5.039% senior unsecured notes due September 18, 2031 (the “2031 Notes”) and US$850 million aggregate principal amount of 5.714% senior unsecured notes due September 18, 2036 (together with the 2031 Notes, the “Notes”).

The Corporation intends to use the net proceeds from the Offering to repay a portion of the advances and drawdowns under certain of the Corporation’s credit facilities incurred in connection with the payment of the purchase price in respect of the acquisition of TRC Companies, which closed on February 24, 2026, and for general corporate purposes.

The Offering is expected to close on or about March 18, 2026, subject to customary closing conditions.

The Notes will be direct, senior unsecured obligations of WSP, will rank pari passu with all of the existing and future senior unsecured indebtedness of WSP, and will be issued pursuant to a trust indenture, as supplemented by a first supplemental indenture in respect of the Notes, each dated as of March 18, 2026.

The Corporation is offering the Notes pursuant to an exemption under the Securities Act of 1933, as amended (the “U.S. Securities Act”). The initial purchasers of the Notes will offer the Notes only to persons reasonably believed to be “qualified institutional buyers” in reliance on Rule 144A under the U.S. Securities Act or outside the United States to non-U.S. persons in reliance on Regulation S under the U.S. Securities Act. The Notes have not been and will not be registered under the U.S. Securities Act or the securities laws of any other state or jurisdiction and may not be offered or sold in the United States absent registration under, or an applicable exemption from the registration requirements of, the U.S. Securities Act. The Notes have not been and will not be qualified for sale to the public under applicable securities laws in Canada and, accordingly, any offer and sale of the Notes in Canada will be made on a basis which is exempt from the prospectus requirements of such securities laws.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any offer to sell or a solicitation of an offer to buy the Notes in any jurisdiction where it is unlawful to do so.
