Closing of Additional $125 Million Senior Unsecured Notes

GlobeNewsWire | May 19, 2026
First Quarter 2026 Financial Highlights

North American Construction Group Ltd. (“NACG” or “Corporation”) (TSX: NOA / NYSE: NOA) today announced that its 2026 Annual General and Special Meeting of shareholders will be held on May 20, 2026. The record date for voting at the Annual General and Special Meeting has been set as April 13, 2026. A copy of the notice, agenda and associated materials will be distributed to shareholders by normal distribution methods prior to the meeting and will also be made available on the Corporation’s website at that time. 

Financial Results for the First Quarter 2026

The Corporation also announced that the Board of Directors has adopted By-Law No.3 (“Advance Notice By-Law”), similar to the advance notice by-laws adopted by many other Canadian public companies, to provide a clear process for shareholders to follow for director nominations and will help ensure that all shareholders receive adequate notice and information about director nominees in order to exercise their voting rights in an informed manner.

Declaration of Quarterly Dividend

The Advance Notice By-Law establishes the conditions and framework under which registered or beneficial owners of common shares of NACG may exercise their right to submit director nominations by fixing a deadline by which such nominations must be submitted by a shareholder to NACG prior to any annual or special meeting of shareholders, and sets forth the information that a shareholder must include in the notice to NACG for the notice to be in proper written form in accordance with the Canada Business Corporations Act (the “Act”).

Outlook for 2026

The Advance Notice By-Law is effective immediately and will be placed before Shareholders for approval, confirmation and ratification at the next Annual and Special Meeting of Shareholders of the Corporation. Pursuant to the provisions of the Act, the Advance Notice By-Law will cease to be effective unless it is approved, ratified and confirmed by a resolution adopted by a majority of the votes cast by the shareholders of the Corporation at the Meeting.

About the Company

North American Construction Group Ltd. is a premier provider of heavy civil construction and mining services in Australia, Canada, and the U.S. For over 70 years, NACG has provided services to the mining, resource and infrastructure construction markets.
