ACHESON, Alberta, March 11, 2026 (GLOBE NEWSWIRE) — North American Construction Group Ltd. (“NACG”) (TSX:NOA/NYSE:NOA) today announced results for the fourth quarter and year ended December 31, 2025. Unless otherwise indicated, figures are expressed in Canadian dollars with comparisons to prior periods ended December 31, 2024.

• Combined revenue was $344.0 million and decreased 7.7% (reported revenue of $305.6 million, no change)
• Combined gross profit was $29.3 million (8.5%) and decreased 35.9% (reported gross profit of $38.8 million (12.7%), decreased 3%)
• Adjusted EPS was $(0.14) and decreased from $1.01 (basic income per share of $0.00, decreased from $0.13)
• Adjusted EBITDA was $77.6 million and decreased 28.7% (net income of $0.1 million, decreased 96%)
• Free cash flow was an inflow of cash of $57.4 million and increased $7.0 million
• Net debt was $878.5 million and decreased $25.5 million during the quarter

Fourth Quarter 2025 Operational & Corporate Highlights:

Fourth quarter operational and corporate achievements underscored our focus on growth, efficiency, and execution as we grow our scopes of work and set a strong foundation for future performance.

• The Fargo project progressed during the quarter and is nearing 85% of completion with our earthworks scopes advancing as planned. The joint venture project team provided a late-stage update with approximately $50 million of cost increases for scopes related to structures, railroads and aqueducts. Our share of the late change was one-time catch-up of $13 million and severely impacted both adjusted EBITDA and earnings per share.
• Australian operations delivered record fourth-quarter combined revenue, up 10% year-over-year, fueled by higher volumes from newly commissioned growth assets, recent contract wins and strong site performance and equipment utilization. Above average wet weather late in the quarter impacted the mines in Queensland and had a pronounced effect on the Carmichael mine given the alliance-type arrangement at that site.
• Our oil sands operations remained stable, with consistent equipment and personnel utilization from Q3 to Q4 with mechanical availability challenges having a slight impact on margins.
• On December 18, 2025, we executed a share purchase agreement to acquire Iron Mine Contracting (“IMC”), a privately owned Western Australia diversified mining services contractor. Together with our existing Australian operations, we believe the transaction will establish us as a national Tier 1 contractor in Australia, that it will broaden the regional client base, enhance the local operating platform, and position the business to participate in long-term, capital-intensive mining development programs across the country.

“2025 marked a year of record revenue for NACG, reflecting the continued growth and diversification of our global platform,” Barry Palmer, President and CEO of NACG commented. “However, earnings during the year were severely impacted by a number of extraordinary one-time project-level adjustments. Specific to the fourth quarter, we recognized a life-to-date adjustment for updated cost to complete of the structures, railroads and aqueducts within the Fargo-Moorhead flood diversion project. Notably, our portion of the project, the large-scale earthworks, have continued to perform well – as expected. In addition, above average rain events in Queensland had a negative impact late in the quarter.”

“Looking ahead, we are entering 2026 with a very different, significantly more positive and stable outlook based on clear operational priorities and strong demand across our markets,” Palmer continued. “In Australia, we are focused on optimizing our maintenance labour, improving inventory management and reducing overhead costs, while continuing to pursue growth opportunities across the region. We also look forward to welcoming Iron Mine Contracting in the coming weeks, which will expand our footprint in Western Australia and further strengthen our platform in the country. In the oil sands region, we are looking at right-sizing our fleet and improving mechanical availability as we position the business to better capture continued strong demand for mining services. A recent win in the region provides confidence of this continuing demand. In infrastructure, the successful execution of our scope of the Fargo-Moorhead project continues to strengthen our track record, and we are actively pursuing opportunities across Canada and the U.S. where our large-scale earthworks capabilities provide a clear competitive advantage.”

Financial Results for the Fourth Quarter 2025:

Combined revenue and reported revenue were generated during the quarter by the following primary segments:

• Heavy Equipment – Australia revenue increased 10% to $175.9 million from $160.3 million, primarily due to scope expansion on existing projects and continued higher volumes from three major Australian contracts secured over the past year.
• Heavy Equipment – Canada revenue decreased 10% to $127.9 million from $141.6 million, primarily due to reduced scopes at the Syncrude mines and the divestiture of the ultra-class 797 fleet, partially offset by the ramp-up of a stream diversion project at the Kearl mines.
• Revenue generated by joint ventures and affiliates, net of eliminations, decreased 43% to $38.4 million from $67.1 million, primarily attributed to the combination of a $12.9 million adjustment to Fargo revenue, reflecting updated forecasted costs associated with the bridge portion of the project, decreased activity from the Mikisew North American Limited Partnership, and lower revenue contributions from the Nuna Group of companies.

Gross profit for the current quarter came in lower than the prior year. Heavy Equipment – Australia recorded a steady gross margin percentage in the current year of 15.5%, compared to the prior year 15.2%. Heavy Equipment – Canada margins were impacted by mechanical availability issues driving higher costs. Combined gross profit was largely impacted by the downward revision to the forecast margin on the Fargo project.

The Q4 adjusted EBITDA was lower year-over-year due to the same factors that impacted gross profit and equity earnings on our joint ventures. Adjusted EPS of $(0.14) compared to $1.01 in the prior year Q4 reflects our earnings and the impact of a higher average share count of 28.2 million (up from 26.8 million in 2024 Q4), driven by the issuance of 3.0 million shares from convertible debentures in February 2025, partially offset by share repurchases.

Strong free cash flow for the quarter was $57.4 million and was primarily based on adjusted EBITDA of $77.6 million offset by sustaining capital additions ($7.6 million) and cash interest expense ($15.3 million).

Declaration of Quarterly Dividend

On March 9, 2026, the NACG Board of Directors declared a regular quarterly dividend (the “Dividend”) of twelve Canadian cents ($0.12) per common share, payable to common shareholders of record at the close of business on March 26, 2026. The Dividend will be paid on April 9, 2026, and is an eligible dividend for Canadian income tax purposes.

Outlook for 2026

Our operational priorities for 2026 are:

• Safety – safety-first mentality across all global operations – ensuring EVERYONE GETS HOME SAFE;
• Australian workforce mix – optimize heavy equipment maintenance workforce mix in Australia, following the improvements implemented in the second half of 2025;
• Cost reduction – following two years of major growth in Queensland, review and reduce discretionary operating costs while fully maintaining customer requirements;
• Integration – upon the expected completion of the Iron Mine Contracting transaction, commission the expanded fleet in Western Australia to support growth and operational scale;
• Civil execution – deliver the successful completion of the Fargo-Moorhead flood diversion project, reinforcing our large-scale civil execution capabilities; and
• Mechanical availability – continue to improve mechanical availability and reliability of a right-sized heavy equipment fleet in the oil sands region.

Our growth drivers for 2026 and beyond are the strategic building blocks of our success:

• Scaling into a Tier 1 Contractor in Australia – provides ability to secure Tier 1 scopes in the much sought-after mining regions of Western Australia and Queensland;
• Securing infrastructure awards across North America – targeting nation-building projects in Canada and mass civil earthwork scopes in the United States for which we have deep experience and expertise; and
• Expanding mining services in Canada and the United States – leveraging our over 70 years of experience, ensuring we are front and center as ever increasing mine scopes in both countries are issued and awarded.

The following table provides projected key measures for 2026 and actual results of 2025. Inclusive of IMC, the 2026 outlook is based on strong proforma contractual backlog of $3.9 billion, $1.2 billion of which relates to 2026, and a total bid pipeline of $12.6 billion. The bid pipeline amount includes $4.6 billion in active tender.

⁽ⁱ⁾See “Non-GAAP Financial Measures”.

“Our 2026 outlook is supported by strong visibility, with approximately $1.2 billion of revenue already secured, representing roughly 75% of our midpoint revenue guidance,” said Jason Veenstra, Chief Financial Officer of NACG. “Beyond that, we continue to see a promising bidding environment with a sizeable pipeline currently already in active tender and procurement processes. Based on historical performance and current operating plans, we expect a stable first half of 2026 fairly consistent with the Q4 run rate, excluding the Fargo impacts, followed by stronger second half of the year as newly commissioned equipment, IMC integration benefits, and typical seasonal activity drive increased performance.”

Basis of Presentation

We have prepared our consolidated financial statements in conformity with accounting principles generally accepted in the United States (“US GAAP”). Unless otherwise specified, all dollar amounts discussed are in Canadian dollars. Please see the Management’s Discussion and Analysis (“MD&A”) for the three months and year ended December 31, 2025, for further detail on the matters discussed in this release. In addition to the MD&A, please reference the dedicated 2025 Q4 Results Presentation for more information on our results and projections which can be found on our website under Investors – Presentations.

Change in Significant Accounting Policy – Basis of Presentation

Effective the first quarter of 2025, we changed our accounting policy for the classification of heavy equipment tires. These tires are now recognized as property, plant, and equipment on the Consolidated Balance Sheets and are amortized through depreciation on the Consolidated Statements of Operations and Comprehensive Income. Previously, all tires were classified as inventories and expensed through cost of sales when placed into service. This change in accounting policy provides a more accurate reflection of the role of tires as components of the heavy equipment in which they are utilized, aligning the accounting treatment with the economic substance of their use.

We have applied this change retrospectively in accordance with Accounting Standards Codification (“ASC”) 250, Accounting Changes and Error Corrections, by restating the comparative period. For further details regarding the retrospective adjustments, refer to note 24 in the consolidated financial statements for the period ended December 31, 2025.

Non-GAAP Financial Measures

This press release presents certain non-GAAP financial measures, non-GAAP ratios, and supplementary financial measures that may be useful to investors in analyzing our business performance, leverage, and liquidity. A non-GAAP financial measure is defined by relevant regulatory authorities as a numerical measure of an issuer’s historical or future financial performance, financial position or cash flow that is not specified, defined or determined under the issuer’s GAAP and that is not presented in an issuer’s financial statements. A “non-GAAP ratio” is a ratio, fraction, percentage or similar expression that has a non-GAAP financial measure as one or more of its components. Non-GAAP financial measures and ratios do not have standardized meanings under GAAP and therefore may not be comparable to similar measures presented by other issuers. They should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. A “supplementary financial measure” is a financial measure disclosed, or intended to be disclosed, on a periodic basis to depict historical or future financial performance, financial position or cash flows that does not fall within the definition of a non-GAAP financial measure or non-GAAP ratio. The non-GAAP financial measures and ratios we present include, “adjusted EBIT”, “adjusted EBITDA”, “adjusted EBITDA margin” “adjusted EPS”, “adjusted net earnings”, “backlog”, “capital additions”, “capital expenditures, net”, “capital inventory”, “capital work in progress”, “cash liquidity”, “cash related interest expense”, “cash provided by operating activities prior to change in working capital”, “combined backlog”, “combined gross profit”, “combined gross profit margin”, “equity investment depreciation and amortization”, “equity investment EBIT”, “equity method investment backlog”, “free cash flow”, “general and administrative expenses (excluding stock-based compensation)”, “growth capital”, “growth spending”, “invested capital”, “margin”, “net debt”, “net debt leverage”, “senior-secured debt”, “share of affiliate and joint venture capital additions”, “sustaining capital”, “total capital liquidity”, “total combined revenue”, and “total debt”. We also use supplementary financial measures such as “gross profit margin” and “total net working capital (excluding cash and current portion of long-term debt)” in our MD&A. Each non-GAAP financial measure used in this press release is defined under “Financial Measures” in our Management’s Discussion and Analysis filed on EDGAR on the SEC website at www.sec.gov or on the CSA website at www.sedarplus.com and on our company website at www.nacg.ca.
