## Exhibit 99.1

**EXHIBIT 99.1**

**North American Construction Group Expands Key Contract in Queensland Australia**

**Increases Revenue Visibility and Contractual Backlog by $125 Million**

ACHESON, Alberta, April 21, 2026 (GLOBE NEWSWIRE) -- North American Construction Group Ltd. ("NACG" or "the Company") (TSX:NOA.TO/NYSE:NOA), a premier global provider of heavy civil construction and mining services, today announced that its wholly owned subsidiary MacKellar Group ("MacKellar") has amended and expanded an existing five-year contract with a leading metallurgical coal producer in the state of Queensland, Australia. The previous contract, announced in August 2024, had transitioned equipment under contract from dry rental to fully maintained fleets and awarded the construction of an on-site maintenance facility.

The amended and expanded five-year contract maintains the expiry date of September 30, 2029 and continues to qualify as contractual backlog based on minimum hour commitments in the agreement. The expanded scope, which includes additional fully maintained equipment and related services, is expected to generate approximately $125 million of incremental revenue and increases MacKellar's scope at that mine site by approximately 50%. The expanded contract is consistent with the financial outlook previously contemplated in the Company's full year 2026 guidance.

The expanded scope is set to commence May 1, 2026 and reach full run rate by August 2026. Of the thirteen additional units supporting this growth, eight Komatsu 240-ton haul trucks were already purchased in December 2025 and publicly announced as part of the Company's fleet optimization initiatives, reflecting NACG's early positioning for this expected customer demand. The remaining five units are expected to be acquired as growth capital during the second and third quarters of 2026 at an estimated cost of approximately $25 million.

"This contract expansion reflects the confidence our customer continues to place in our team and MacKellar's strong operating performance," said Barry Palmer, Chief Executive Officer of NACG. "It adds meaningful revenue visibility and contractual backlog, while also highlighting the disciplined way we deploy capital against identifiable demand. With MacKellar and Iron Mine Contracting, we continue to strengthen our Tier 1 contractor platform in Australia and enhance our ability to capture additional opportunities across the region."

**About the MacKellar Group**

Operating since 1966, and as a wholly owned subsidiary of NACG since 2023, MacKellar has an enviable reputation in Australia for performance and reliability. MacKellar and the recently acquired Iron Mine Contracting have established a Tier 1 contractor platform to serve Australian mining customers country wide.

**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.
