On April 13, 1953, North American Road Builders was first incorporated by two brothers, Ivan and Bob Gouin, and a single secondhand bulldozer.

For the next 20 years, North American built roads across the province and into British Columbia, while also expanding into industrial construction. The company worked on such massive infrastructure projects as Gardiner Dam and Lake Diefenbaker in southern Saskatchewan, as well as on sections of the Alaska Highway. The company also installed thousands of kilometres of small-inch pipeline to farmers across the province to deliver natural gas.

In 1973, the company made the bold decision to venture north to Fort McMurray. The world’s first large scale commercial oilsands surface mining and refining plant – the Great Canadian Oil Sands – had officially started extracting bitumen from Fort McMurray’s fertile soil in 1967, and North American saw a lot of promise in the area’s future.

Over the following years, North American continued to pave a broader path into the Wood Buffalo region – clearing land, building roads, and working hand-in-hand with the regions two major producers, Suncor and Syncrude.

Then, in 1980, North American began supplementing our fleet with larger and more complex equipment, including dozens of haul trucks, excavators, dozers, and hydraulic shovels.

Over the next two decades, North American continued to grow in pace with the oilsands, offering a vast suite of services, including mining, heavy construction, industrial services, piling and pipeline. Using some of the largest and most technologically advanced equipment in the world, North American had transformed itself into a successful energy contractor that now helped to mine, develop, and reclaim the land.

Then in 2003, an exciting new chapter began for North American after it was purchased by an international investment group. Just three years later, on November 22nd, 2006, North American Energy Partners came into existence after the company was officially listed on both the New York and Toronto Stock Exchanges under NOA.

In the years that followed, North American continued to participate in a number of major infrastructure projects.

Our divisions helped construct the Richmond Speed Skating Oval for the 2010 Vancouver Winter Olympics andRipley’s Aquarium of Canada, which is located at the base of Toronto’s iconic CN Tower.

We also helped install 160-kilometres of the Trans Mountain pipeline expansion through Jasper National Park and Mount Robson Provincial Park, as well as the Burgess Shale UNESCO World Heritage Site. Upon completion, that highly environmentally sensitive project was recognized with an Emerald Award from the Alberta Emerald Foundation, which celebrates environmental leadership and excellence within our province.

Meanwhile, up in the oilsands, North American continued to grow substantially. The Company signed numerous long-term contracts with the country’s biggest energy providers, including a massive 10-year overburden hauling agreement at CNRL that saw North American move twice the amount of earth that was hauled during the construction of the Panama Canal.

Then, in 2012, Martin Ferron was announced as the new President of North American Energy Partners, starting a new chapter in our corporate history.

Under Ferron’s leadership, North American solidified its reputation with shareholders and began working toward a major diversification of the Company.

The first step of that goal took place in 2018, when North American announced that it had acquired a 49% ownership interest in Nuna Logistics Limited. As an established incumbent contractor in Nunavut and the Northwest Territories, the acquisition would prove to be of

mutual benefit to both companies through access to broader equipment fleets, experienced field personnel, and expanded services such as North American’s growing maintenance offerings.

That same year, North American announced the acquisition of a competitor’s mining fleet. The deal greatly expanded the size of our construction fleet, while also delivering additional valuable long-term contractual commitments to our bottom line.

In November of 2018, North American moved into its new 50,000 square foot corporate headquarters and maintenance facility in Acheson, Alberta. While providing a permanent home for the fast-growing company, the move also gave us an opportunity to expand our maintenance offerings, as we continue to service and rebuild heavy equipment for external clients.

In December of 2020, Martin Ferron resigned as CEO of North American Construction Group and took on the role of Executive Chairman. At the same time, Joe Lambert was appointed as President and Chief Executive Officer effective January 1, 2021.

Under Lambert’s experienced guidance, our rapid expansion continued through 2021 when North American acquired DGI Trading of Kempsey, New South Wales, Australia. DGI had long worked hand-in-hand with our maintenance division in sourcing production-critical mining components that we could rebuild from the ground up.

Just a few weeks later, North American was awarded the largest infrastructure project in the Company’s history. Along with our partners Acciona and Shikun & Binui, we were awarded the Fargo-Moorhead Flood Diversion project in North Dakota—a US$3.2 billion flood diversion canal designed to protect their community from disastrous flooding. As part of a highly talented joint venture under ASN Constructors, North American was given responsibility for carving out a 30-mile-long flood diversion canal over a six-year period. Once completed, ASN Constructors will continue to oversee maintenance on the canal for 30 years.

In 2023, North American undertook its most transformative acquisition when we acquired the MacKellar Group. The Australian-based provider of heavy earthworks came with a strong reputation derived from decades of reliable performance. With approximately 450 mobile heavy equipment assets, 1,000 employees—including over 375 maintenance

personnel, and a solid backlog of operating projects, the acquisition vastly expanded North American’s operational footprint and transformed us into an international entity.

Two years later, in December of 2025, North American strengthened its presence in Western Australia with the acquisition of Iron Mine Contracting. The privately owned diversified mining services contractor supports such key commodity sectors such as gold, iron ore and lithium in one of Australia’s most established mining sectors. The acquisition also now classifies North American as a Tier 1 mining contractor on a national scale in Australia.

In January of 2026, Joe Lambert resigned as President and CEO of North American Construction Group, and Chief Operating Officer Barry Palmer, a 40+ year veteran of the company, assumed the role of President & Chief Executive Officer on January 21st, 2026.

Under the leadership of Chief Executive Officer Barry Palmer and his executive team, North American will continue blazing a new path, searching for the right opportunities to continue growing and diversifying the Company, while also providing safe and efficient services to all of our clients.

From a single bulldozer to an international heavy construction and mining powerhouse. What an amazing journey it has been.
