LETTER TO SHAREHOLDERS To my fellow shareholders, As is customary to accompany our annual report and having assumed the role in January 2026, this is my first time writing a letter to you as the chief executive here at North American. Given the transition in leadership, I believe this letter serves an important purpose: to provide a clear update on how the business is being operated under my direction, where we are building momentum, and how we are positioning NACG to deliver sustained, long-term shareholder value. As an operationally focused executive, my instinct is to press forward with action plans, looking for solutions, and I'm excited for the upcoming year given the opportunities we have in front of us. Since late 2023, I have spent the majority of my time in Australia, working closely with our teams as we scale our operations. We are seeing processes mature, assets commissioned on schedule, and contracts executed to plan. MacKellar continues to earn extensions and expansions from customers, reflecting strong operational performance and reinforcing our long-term growth outlook. With the acquisition of Iron Mine Contracting, we are looking forward to continued growth in Western Australia and being classified as Tier 1 mining contractor on national scale in Australia. As MacKellar has delivered exceptional organic growth since 2020, we intend to build on that momentum with a larger and more diversified platform, particularly in rare earth & critical mineral projects in Western Australia, where the continent has increasingly emerged as a strategic hub for the West's critical mineral supply chains. Moving to our infrastructure business in North America, we continue to experience tailwinds as nation building projects in Canada and the U.S. are moving from announcement to shovels in the ground. The Fargo-Moorhead flood diversion project has strengthened our credibility for large civil earthworks programs. Late-stage revisions on Fargo severely impacted our 2025 financials while the earthworks scopes that we are responsible for have progressed as planned and we are very proud of our team's performance. The project enhances our track record and positions us for similar near-term opportunities. Our focus is securing work where we have a clear competitive advantage, particularly in mine site civil scopes and subcontracted earthworks roles on large infrastructure programs. We are tracking various infrastructure initiatives and are well placed moving forward: • Major Projects in Canada: NACG and Nuna Group of Companies (Nuna) are teamed and in position to advance on northern nation-building projects in Canada. Across three defined projects, the partnership is progressing from early market engagement to formal qualification, with multiple tenders anticipated in 2026; 2 NORTH AMERICAN CONTRUCTION GROUP

![LOGO](g57687g00a05.jpg)

• Mass Civil Earthwork Scopes in the United States: NACG is actively pursuing opportunities as a subcontractor with shortlisted consortia on major U.S. opportunities focused on mass civil earthworks. Upcoming pricing and award milestones are expected to open a capital-light growth channel in the U.S. civil earthworks market; • Defense Construction Canada Portfolio: Nuna, as an Inuit-owned partnership with Arctic defense construction experience, is advantageously positioned to perform scopes of work under the Northern Basing Initiative. Multi-year scopes in northern Canada will be awarded as defense spending is sequenced and released; and • Critical Minerals Infrastructure: NACG and Nuna are in advanced strategic positions to secure critical mineral site access projects across Canada. These high-profile projects are now moving forward into the active bid phase, where NACG is strongly positioned for successful contract awards. And lastly, I'll end my remarks on Canadian mining, where I have spent the majority of my 44-year career here at NACG. We are assessing the fleet in the oil sands region to assure operational readiness for the continued strong demand. Our commitment to maintaining a ready fleet in the oil sands will position us to capture a stronger winter 2026/2027 demand and the associated earnings opportunities. We're getting back to the basics of our success in the region: safety-first mentality, operational excellence and world-class maintenance. When these are executed consistently, we earn our customers' trust and long-term work. That is how this business has created value for decades. 2026 will be a banner year for us here at NACG. Having spent over four decades with this organization, I have seen our cycles and our inflection points, and the momentum building today is clear. The operational groundwork laid over the past several years is translating into visible traction, with the second half of 2026 expected to reflect higher activity levels across the platform. Our focus remains straightforward: disciplined capital allocation, reliable and safe execution and sustainable growth that compounds long-term shareholder value. Thank you for your continued support of our company. Sincerely, Barry Palmer, President & CEO North American Construction Group

SAFETY SUSTAINABILITY EXECUTION 4 NORTH AMERICAN CONTRUCTION GROUP

------

![LOGO](g57687g00a07.jpg)

SAFETY As a mining and heavy civil contractor, the strength of our business is built on the strength of our safety performance. Safe operations are sustainable operations. We operate with a clear commitment to protecting our people, our communities, and the environment, and we actively work to identify, understand, and manage the hazards and environmental impacts inherent in our daily activities. In 2025, we delivered a Total Recordable Injury Rate (TRIR) of 0.39, outperforming our target of 0.50. This achievement reflects the discipline of our teams and the ongoing evolution of our safety management systems. We remain focused on refining our processes, strengthening field execution, and embedding best practices that proactively reduce risk. We continue to operate on the fundamental belief that all workplace incidents are preventable. As a longstanding core objective at NACG, TRIR remains a primary benchmark of our safety performance and an important measure of alignment with client and industry standards. Maintaining a strong TRIR performance is not only a metric of success—it is a reflection of operational excellence. Beyond measuring actual incidents, we place equal emphasis on understanding and managing the potential for serious harm. Significant Incident Frequency Potential (SIFp) is a critical leading indicator that reinforces our proactive risk management approach. By identifying events with high-risk potential—even when no injury occurs—we strengthen our ability to anticipate hazards, improve controls, and prevent escalation. This forward-looking focus ensures we are addressing risk before it manifests in serious outcomes. Looking to 2026, we will continue advancing our integration of Human and Organizational Performance (HOP) principles into our safety framework. Recognizing that human error is inevitable, we design systems that are resilient, supportive, and capable of absorbing mistakes without catastrophic consequence. We foster an environment of open communication, encourage reporting and dialogue at all levels, and learn from both successes and setbacks. Through this continuous learning culture, we reinforce our commitment to ensuring everyone gets home safely while sustaining the operational excellence our stakeholders expect. SAFETY PRINCIPLES Promote safe behavior is the foundation of our culture and daily operations. Demonstrate visible and engaged leadership from both executive and line management. Encourage proactive participation from every employee in safety and environmental programs and processes. Protect the physical, psychological, and social well-being of our workforce. Minimize the environmental impact of our activities at every worksite. Recognize achievements while continuously striving for higher standards of performance. Ensure full compliance with all applicable legislation and regulatory requirements. Embed health, safety, and environmental protection as integral drivers of operational success. Strengthen our health, safety, and environmental systems through accountability, continuous improvement, and a commitment to excellence. Uphold our commitment to people, relationships, and safety to attract and retain top industry talent. ANNUAL REPORT 2025 5

SUSTAINABILITY From their beginnings, both NACG and MacKellar have built strong, disciplined cultures grounded in safety and cost-effective execution. We view this culture not simply as an operational strength, but as a defining contributor to our sustained performance. We recognize that long-term success depends on more than financial results alone. It requires a clear and ongoing commitment to sustainability — balancing environmental stewardship, social responsibility, and economic performance. To that end, we continuously strengthen our systems and processes to align with our sustainability principles while meeting the evolving expectations of our customers, partners, employees, and stakeholders. Just as safety and cost discipline are shared accountabilities across every level of our organization, sustainability is equally collective in nature — embedded in how we plan, operate, and make decisions every day. AREAS OF FOCUS 1 Leadership Diversity & Governance Strength Building a resilient and high-performing organization requires diversity of thought, experience, and background. In 2026, we will continue to look at opportunities to build on gender diversity at our leadership levels as part of our broader governance and succession strategy. Strengthening diversity at the top enhances decision quality, risk management, and long-term shareholder value. 2 Emissions & Operational Efficiency Our Scope 1 emissions primarily result from diesel combustion within our off-road heavy equipment fleet. We are committed to reducing these emissions through improved fleet utilization, reduced idle time, disciplined operational practices, and the evaluation of emerging technologies that support lower-carbon operations. 3 Safety Performance – TRIR ≤ 0.50 We maintain our longstanding commitment that all workplace incidents are preventable. For 2026, we will continue targeting a Total Recordable Injury Rate (TRIR) of 0.50 or less, supported by: • Strengthened field-level leadership accountability • Continued integration of Human & Organizational Performance (HOP) principles • Proactive monitoring of high-potential events (SIFp focus) • Ongoing system refinement and cultural reinforcement TRIR remains an industry-recognized benchmark and a critical performance indicator for clients, regulators, and stakeholders. Sustained safety excellence is fundamental to protecting our people, maintaining client confidence, and ensuring long-term operational stability. 6 NORTH AMERICAN CONTRUCTION GROUP

Management's Discussion and Analysis

March 11, 2026

*The following Management's Discussion and Analysis ("MD&A") should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2025, and notes that follow. These statements have been prepared in accordance with United States ("US") generally accepted accounting principles ("GAAP"). Except where otherwise specifically indicated, all summary information contained in this MD&A has also been prepared in accordance with GAAP and all dollar amounts are expressed in Canadian dollars. The audited consolidated financial statements and additional information relating to our business, including our most recent Annual Information Form ("AIF") and our report pursuant to Canada's Modern Slavery Legislation (an Act to enact the Fighting Against Forced Labour and Child Labour in Supply Chains Act) are available on the Canadian Securities Administrators' SEDAR+ System at<u> </u>*<u>www.sedarplus.com</u>*, the Securities and Exchange Commission's website at* <u>www.sec.gov</u> *and our company website at<u> </u>*<u>www.nacg.ca</u>*.* 

*Our MD&A presents non-GAAP financial measures, non-GAAP ratios, and supplementary financial measures that provide useful financial information to our investors to better understand our performance. A "non-GAAP financial measure" is a financial measure that depicts historical or future financial performance, financial position or cash flows, but excludes amounts included in, or includes amounts excluded from, the most directly comparable GAAP measure. 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. 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. In our MD&A, we use non-GAAP financial measures and ratios such as "adjusted EBIT", "adjusted EBITDA", "adjusted EBITDA margin", "adjusted EPS", "adjusted net earnings", "backlog", "capital additions", "capital expenditures, net", "capital inventory", "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 capital additions", "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", and "total combined revenue". 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. We provide tables in this document that reconcile non-GAAP and capital management measures used to GAAP measures reported on the face of the consolidated financial statements. A summary of our financial measures is included below under the heading "Financial Measures".*

<sup>(i)</sup>See "Non-GAAP Financial Measures".

<sup>(ii)</sup>The prior year amounts are adjusted to reflect a change in accounting policy. See "Accounting Estimates, Pronouncements and Measures".

<sup>(iii)</sup>Combined gross profit margin is calculated using combined gross profit over total combined revenue.

<sup>(iv)</sup>Certain prior period costs within the Fargo joint venture have been reclassified from non-operating to operating to better align with NACG classifications. This reclassification has no impact on revenue, income before taxes, or net income.

<sup>(v)</sup>Adjusted EBITDA margin is calculated using adjusted EBITDA over total combined revenue.

For the year ended December 31, 2025, we delivered solid top-line growth, with revenue increasing to $1,284.3 million and total combined revenue reaching $1,496.6 million, up 6% from the prior year. This growth was primarily driven by continued expansion in our core operating segments, particularly in Australia, and supported by steady demand in Canada. For the year ended December 31, 2025, adjusted EBITDA was $356.5 million, down from $410.1 million in 2024, with the margin declining to 23.8% from 29.0%. This decrease reflects lower gross profit and reduced equity earnings from joint ventures, despite higher total combined revenue. Adjusted EPS also declined to $1.06 from $3.78 in the prior year, primarily due to lower adjusted net earnings and increased non-recurring charges. Despite these challenges, free cash flow improved significantly to $61.2 million, up from $18.0 million in 2024, supported by strong cash generation from operating activities and disciplined capital spending.

**Heavy Equipment – Australia commentary** 

Revenue for the Heavy Equipment – Australia segment, primarily driven by the MacKellar Group, increased by $99.3 million (17%) year-over-year. The increase reflects continued expansion of large-capacity heavy equipment fleet and incremental contract activity during the year. The fleet growth and contract wins over the last year drove increased production volumes, particularly as weather conditions improved following the excessive rainfall experienced in the first quarter. Although heavy rainfall in February and March, and into April, reduced utilization and constrained operating efficiency early in the year, improved conditions and steady demand in subsequent quarters supported stronger production levels. Overall, the segment delivered higher annual revenue despite the operational disruptions experienced in the first half of the year.

Gross profit was $115.1 million, or 16.7% of revenue, versus $132.2 million (22.4% of revenue) in the prior year. The year-over-year decrease in margin performance was primarily driven by abnormal operating conditions experienced in the first half of 2025. Excessive rainfall in February and March significantly impacted productivity at the Carmichael mine, resulting in lower equipment utilization and higher costs associated with weather recovery activities such as dewatering, site cleanup, and maintenance inefficiencies. These rain-related disruptions continued into April, further constraining operational efficiency early in the year. In addition, the segment experienced temporary margin pressure from a short-term overreliance on subcontractor support as sites ramped up activity levels, increasing external labour costs relative to normal operating conditions. While revenue increased year-over-year due to fleet expansion and incremental contract activity, the change in contract and mine site mix combined

with the weather-driven cost impacts more than offset the benefit of higher volumes. As operating conditions improved in the latter part of the year, performance in the segment stabilized.

**Heavy Equipment – Canada commentary** 

Heavy Equipment – Canada revenue increased by $23.8 million (or 4%) from the prior year. Demand for large-capacity heavy equipment in the oil sands region remained generally strong throughout the year, with the Millennium mine continuing to be a primary driver of utilization and top-line performance. However, the segment experienced notable operational headwinds during 2025, including an extreme cold snap in the first quarter, a temporary customer-requested shutdown in the second quarter, and reduced scope and demobilization activity at Syncrude in the third quarter. Despite these disruptions, full-year revenue increased relative to 2024, reflecting sustained customer demand and fleet activity across the operating sites.

Gross profit was $38.6 million, or 6.7% of revenue, compared to $67.4 million, or 12.1% of revenue, in the comparative prior year period. The year-over-year decrease in margin performance was primarily driven by abnormal operational disruptions and cost pressures experienced throughout 2025. The segment was impacted in the first quarter by an extreme cold snap across the oil sands region, which resulted in elevated idle time, reduced operating efficiency, and higher costs required to sustain operations in prolonged frigid temperatures. In addition, extraordinary component failures related to a discontinued third-party supply agreement further increased costs and negatively affected margins. The segment also faced disruption in the second quarter due to an unexpected customer-requested temporary shutdown of activity, which constrained productivity and contributed to inefficiencies. Later in the year, reduced scopes at the Syncrude mines and associated demobilization activities further pressured gross profit, while we continued investing in fleet repairs and maintenance. Although demand for large-capacity heavy equipment remained generally strong, these operational challenges and higher cost conditions more than offset the benefit of revenue growth.

**Consolidated commentary** 

Total combined revenue for the year was $1,496.6 million, representing a $81.3 million (6%) increase over the prior year $1,415.3 million. Of this total, $118.5 million relates to growth in reported revenue from our main operating segments discussed above. Our proportionate share of revenue from equity-consolidated joint ventures totaled $212.3 million, a decrease of $37.3 million compared to $249.5 million in 2024. This decline was primarily driven by reduced activity at the Nuna Group of Companies ("Nuna"), together with the impact of a settlement by Nuna that resulted in a revenue reversal. While Nuna's volumes were lower, progress on the Fargo project provided some offset, with the project advancing from 30% to 84% completion during the year, despite two downward margin revisions reflecting updated cost estimates.

Combined gross profit was $163.5 million, or 10.9% of revenue, representing a decrease of $70.6 million, or 9.1% of revenue, compared to the prior year. The reduction was largely due to lower margins from the operating segments, and lower margin contribution from the Fargo project. Another downward revision to the Fargo project forecast was recorded in Q4, resulting in a $12.9 million cumulative catch-up reduction at our consolidated level. While the earthworks segment of the project remained on schedule, the adjustment is based on a late-stage forecast update from the joint venture team. This update specifically addresses increased costs in the structure, railroads, and aqueduct components, and incorporates refined cost estimates as the project nears its final stages. Earlier in the year, in Q2, a $7.7 million cumulative catch-up reduction in equity earnings was recognized, primarily as a true-up to revenue following a revision in the overall Fargo project forecast subsequent to the settlement of contractual negotiations. The combination of the Q2 and Q4 margin adjustments, amounting to a total of $20.6 million, led to a significant reduction in the project's overall profitability for the year, as these adjustments reflected increased costs and lower margins across key project components. Additionally, Nuna's gross profit was impacted by a one-time write-down related to a negotiated settlement with a customer facing insolvency, which compounded the negative impact of reduced volumes.

General and administrative ("G&A") expenses, excluding stock-based compensation, were $50.8 million, representing 4.0% of revenue, consistent with the prior year percentage of 3.9%, when expenses were $45.9 million. The increase in absolute G&A expense is primarily attributable to ongoing investments in the integration and expansion of our Australian operations during the early part of 2025, increased business development efforts, acquisition-related expenses for IMC in Q4, and other organizational realignment costs. Although revenue grew year-over-year, the rise in G&A spending reflects our commitment to supporting its growth trajectory and the operational requirements.

Adjusted EBITDA and margin of $356.5 million and 23.8% compared to $410.1 million and 29.0% in the prior year. The 5.2% decrease in margin can be explained by the impacts to gross profit and equity earnings on our joint ventures.

Depreciation expense increased to $217.2 million, up from $185.0 million in the prior year, with the equivalent rates being 16.9% and 15.9% of revenue. The higher depreciation rates were influenced by increased fleet size in Australia and higher idle time in Canada during periods of cold weather in Q1 and Q4 of 2025.

Adjusted earnings were $30.4 million, compared to $101.3 million in the prior year, generating $1.06 of adjusted earnings per share ("adjusted EPS"), compared to $3.78 in 2024. The decline reflects lower adjusted EBITDA, higher depreciation expense, and the operational challenges described above, as well as the impact of lower equity earnings. Average outstanding shares during the year were 28.7 million compared to 26.8 million in 2024, an increase of 1.9 million shares as the issuance of 3.0 million shares in February 2025 from convertible debentures were offset by share purchase program activity over the past twelve months.

Free cash flow for the year ended December 31, 2025, totaled $61.2 million, compared to $18.0 million in the prior year. This figure was primarily driven by adjusted EBITDA of $356.5 million, offset by sustaining capital expenditures of $213.2 million, cash interest payments of $56.1 million, and current income taxes of $8.0 million.

SIGNIFICANT BUSINESS EVENTS

**Purchase and Sale of Heavy Equipment Fleet** 

On December 1, 2025, we signed an agreement with a private heavy equipment rental provider to divest 26 Caterpillar 797 (400-ton) haul trucks located in the oil sands region and to acquire 7 Hitachi 830 (240-ton) haul trucks located in Australia. The transaction intends to accelerate fleet deployment and utilization in support of contracted long-term growth in Australia in 2026, while reducing leverage and optimizing capital allocation.

The agreement reduced outstanding equipment-related debt of Canadian assets and materially shortened the deployment lead time of the Hitachi 830 haul trucks to Australian-based customers. The acquired units are expected to be mobilized and deployed on long-term contracts in 2026, supporting expansion within the Heavy Equipment – Australia segment.

Of the 26 units, NACG directly divested 15 units and the Mikisew North American Limited Partnership ("MNALP") divested 11 units. For NACG's portion of the transaction, consideration included $1.8 million in cash, the buyer's assumption of finance obligations associated with the assets, and the acquisition of 7 haul trucks valued at $34.0 million for identified growth opportunities in Australia. For MNALP's portion, consideration included cash proceeds of $17.0 million and the buyer's assumption of the equipment financing, comprised of both finance leases and finance obligations.

The purchase and sale agreement was reflected in our financial statements for the year ending December 31, 2025. Equipment financing transfers were completed after the reporting period. As of year-end, our Consolidated Balance Sheets included $16.6 million in contract assets from the sale, $17.3 million in the current portion of long-term debt due to financing assignments, and a $0.4 million net liability associated with our equity investment in affiliates and joint ventures. These amounts were removed after the financing obligations were reassigned on January 29, 2026.

**Acquisition of Iron Mine Contracting** 

On December 18, 2025, we entered into a Share Purchase Agreement (the "IMC Purchase Agreement") to acquire 100% of the voting shares and business of DCL Corp Pty Ltd and Iron Hire Pty Ltd., together referred to as Iron Mine Contracting ("IMC"), a privately owned Western Australia diversified mining services contractor.

Pursuant to the IMC Purchase Agreement, IMC shareholders will receive upfront cash consideration determined based on a formula leveraging IMC's equity book value, subject to certain post-closing adjustments, as well as deferred consideration in the form of a seller takeback financing payable, and contingent consideration.

The acquisition is valued at approximately $125 million in Canadian dollars. The estimated upfront payment of approximately $40 million will be funded by our existing revolving credit facility. In addition, we plan to assume secured equipment financing of $45 million. The remaining $40 million of the consideration will be settled through structured earn-out and deferred payment mechanisms payable to the vendors over the next four years.

The acquisition will strategically expand our footprint in Western Australia, a mining jurisdiction characterized by strong and diversified commodity exposure, including base metals, precious metals, and critical and rare earth

minerals.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. IMC boasts a strong order book, currently exceeding $833 million and including a recently awarded lithium mining contract with a three-year term. This backlog is supported by a strong pipeline of large mining and civil projects.

The transaction is subject to customary closing conditions, including approval by the Australian Competition and Consumer Commission under section 51ABX of the Competition and Consumer Act 2010. The transaction is expected to close early in the second quarter of 2026. The estimate of the financial effect, including the fair value of consideration transferred and the allocation to the acquired assets and assumed liabilities, is pending on the closing date and a formal valuation process. The preliminary purchase price allocation will be determined following the closing date.

**Change in Leadership** 

Effective January 21, 2026, Joe Lambert resigned from his position as President and Chief Executive Officer of NACG to pursue other opportunities. Our Chief Operating Officer, Barry Palmer, has assumed the role of President and Chief Executive Officer. We have begun the process of assessing both external and internal candidates to assume the role on a permanent basis.

Concurrent with this leadership transition, we initiated a strategic review of our heavy equipment fleet in the Canadian oil sands region. The review is intended to assess optimal fleet sizing in light of high sustained customer demand, capital efficiency objectives, and long-term contract visibility. The objective is to ensure we maintain an appropriately scaled, cost-efficient operational fleet capable of delivering timely and effective solutions to our longstanding oil sands customers while maximizing our fleet utilization.

For the three months ended December 31, 2025, revenue was $305.6 million, consistent with revenue of $305.6 million in the same period last year, driven by strong global equipment utilization of 71%. The revenue generated by the Heavy Equipment – Australia segment of $175.9 million represents a $15.6 million increase over 2024 Q4. This increase is primarily the result of scope expansion on existing projects and the commissioning of growth assets, in addition to the continued revenue contribution from a new project that commenced late in 2024. The quarter-over-quarter reduction in Heavy Equipment – Canada segment revenue is primarily driven by the divestiture of the ultra class fleet and reduced scopes at Millennium mine, partially offset by the ramp-up of a stream diversion project at the Kearl mine and increased light civil scopes at Fort Hills mine.

For the year ended December 31, 2025, revenue was $1,284.3 million, up from $1,165.8 million for the year ended December 31, 2024. This growth largely relates to Heavy Equipment – Australia segment revenue, which was driven by the same factors that influenced the quarter. The current year increase in Heavy Equipment – Canada revenue reflects increased mine support activities in the first half of the year at Syncrude mines as well as the same factors that influenced the quarter.

For the three months ended December 31, 2025, depreciation totaled $52.5 million (17.2% of revenue), up from $50.1 million (16.4% of revenue) in the same period last year. The increase in depreciation as percentage of revenue for the Heavy Equipment – Australia segment (12.6% in 2025 Q4 compared to 11.9% in 2024 Q4) is due to changes in fleet composition as fleet expanded in the year. The increase in depreciation as percentage of revenue for the Heavy Equipment – Canada segment (23.5% in 2025 Q4 compared to 22.2% in 2024 Q4) is largely driven by extreme cold weather resulting in elevated idling hours in December 2025.

Depreciation for the year ended December 31, 2025, was $217.2 million (16.9% of revenue), up from $185.0 million (15.9% of revenue) in 2024. Depreciation as a percentage of revenue increased for the Heavy Equipment – Australia segment mainly due to the factor noted above. The increase in depreciation as a percentage of revenue in the Heavy Equipment – Canada segment reflects the factor noted above, as well as higher write-downs related to early component failures and increased idle time during an extended period of severe cold in 2025 Q1.

expense, was $14.9 million, or 4.9% of revenue, for the three months ended December 31, 2025, up from $13.2 million, or 4.3% of revenue, in the same period last year. The current year increase is mostly due to acquisition costs, organizational realignment costs, and the loss on customer bankruptcy all occurring in the quarter, which are all normalized in our adjusted earnings, EBIT, and EBITDA metrics.

For the year ended December 31, 2025, operating income was $109.2 million, down from $153.3 million for the year ended December 31, 2024. G&A expense, excluding stock-based compensation expense, was $50.8 million, or 4.0% of revenue, for the year ended December 31, 2025, up from $45.9 million and 3.9% of revenue, recorded in the year ended December 31, 2024. The year-over-year gross increase was mostly due to the items impacting Q4 above.

For the three months and year ended December 31, 2025, stock-based compensation was an expense of $2.2 million and a benefit of $0.4 million, respectively. For the three months and year ended December 31, 2024, stock-based compensation was an expense of $5.6 million and of $8.7 million, respectively. The year-over-year differences are primarily due to the impact of the fluctuating share price on the carrying value of our liability classified award plans.

---

For the three months ended December 31, 2025, total interest expense increased to $16.0 million from $14.4 million in the prior year. This increase was mainly due to the introduction of senior unsecured notes, which contributed $6.2 million in the quarter, partially offset by lower interest on the Credit Facility as a result of reduced balances and lower variable rates.

For the year ended December 31, 2025, total interest expense was $58.9 million, a slight decrease from $59.3 million in 2024. The year-over-year reduction was primarily driven by lower Credit Facility interest (down $10.7 million) and the discontinuation of customer supply chain financing, offset by $13.5 million in new interest from the senior unsecured notes.

Cash interest expense (excluding non-cash amortization) was $15.3 million for the quarter and $56.1 million for the year, higher than the prior year in the quarter and comparable for the year to date. However, the average cost of debt improved to 6.6% for the quarter (from 6.7%) and 6.4% for the year (from 8.1%), reflecting more favorable borrowing terms and effective debt management.

<sup>(i)</sup>Certain prior period costs within the Fargo joint venture have been reclassified from non-operating to operating to better align with NACG classifications. This reclassification has no impact on revenue, income before taxes, or net income.

For the three months ended December 31, 2025, equity earnings in affiliates and joint ventures generated a net loss of $14.7 million, compared to net income of $5.8 million in the same period of 2024. The decline was primarily driven by reduced project margins at Fargo, following an updated forecast from the joint venture team. This forecast identified higher-than-anticipated costs related to the structure, railroads, and aqueduct components of the project. As a result, a revenue adjustment of $12.9 million was recorded at our level. Additionally, a $4.3 million loss recognized at Nuna in connection with a negotiated settlement with a customer facing insolvency. MNALP continued to deliver stable results, while contributions from other entities remained modest.

On a full-year basis, equity earnings totaled a loss of $11.3 million for 2025, a significant decrease from earnings of $15.3 million in 2024. The primary driver of this loss was a total $20.6 million revenue reversal at the Fargo joint venture due to project forecast revisions, including the Q4 $12.9 million revenue adjustment and an earlier adjustment of $7.7 million in Q2 following the settlement of contract negotiations. While Nuna recorded a net loss for the year due to the Q4 settlement, it achieved a higher margin percentage than in the prior year. MNALP continued to contribute positive earnings, though at lower volumes.

---

For the three months and year ended December 31, 2025, the change in fair value of contingent obligations resulted in a benefit of $17.2 million and $26.9 million, respectively. This compares to an expense of $14.3 million and $53.2 million for the same periods in 2024. These contingent obligations represent the fair value of acquisition-related liabilities from the MacKellar Group acquisition on October 1, 2023, and are subject to periodic remeasurement based on actual and forecasted performance, changes in discount rates, and interest accretion.

| MANAGEMENT'S DISCUSSION AND ANALYSIS | **25** |

---

------

During 2025, estimate adjustments reduced the obligation by $20.1 million in the quarter and $41.7 million for the year, primarily due to actual performance in 2025 falling short of previous expectations and downward revisions to 2026 forecasts. In contrast, the prior year saw increases of $9.5 million and $36.0 million, reflecting upward revisions to forecasted results from newly commissioned growth assets and improved performance from the existing fleet. These estimate-driven fluctuations are excluded from adjusted earnings, as they are non-cash and non-recurring in nature.

Interest accretion on the contingent obligations was $2.9 million for the quarter and $14.8 million for the year, both lower than the prior year. The primary driver of this decrease was the declining balance of the obligation as payments were made and estimate adjustments reduced the liability, with lower discount rates also contributing to the reduction. Unlike estimate adjustments, interest accretion is included in adjusted earnings as it represents the implied financing cost of the vendor-provided consideration.

**Loss on derivative financial instruments** 

On May 29, 2024, we entered into a swap agreement with a financial institution to manage risk associated with our stock-based compensation arrangements. Under the agreement, we swapped 583,725 common shares at a par value of $26.73 and an additional 250,000 shares at a par value of $25.10. The agreements mature on May 31, 2027, and September 30, 2027, respectively, and include provisions for early termination.

For the year ended December 31, 2025, we recognized an unrealized loss of $9.4 million on this swap, reflecting the difference between the par values and the expected share prices at contract maturity. As of December 31, 2025, the TSX closing share price was $19.76, resulting in a fair value liability of $5.4 million recorded in other long-term obligations (see note 15 to the Consolidated Financial Statements). The swap is not designated as a hedge for accounting purposes; therefore, changes in its fair value are recognized in the Consolidated Statements of Operations and Comprehensive Income.

During the year ended December 31, 2024, we realized a gain of $0.2 million from a separate swap agreement, previously recorded as an unrealized gain. This agreement was settled and derecognized from the Consolidated Balance Sheets on January 3, 2024.

<sup>(i)</sup>The prior year amounts are adjusted to reflect a change in presentation. See "Accounting Estimates, Pronouncements and Measures".

For the three months ended December 31, 2025, we recorded income tax expense of $6.4 million. For the year ended December 31, 2025, income tax expense was $22.6 million. This compares to an income tax benefit of $0.8 million and income tax expense of $16.0 million for the three months and year ended December 31, 2024, respectively.

The increase in income tax expense and the effective tax rate in 2025 reflects the mix of taxable earnings and losses across jurisdictions with differing tax rates, combined with withholding taxes and permanent differences on our stock-based compensation. This mix, together with non-deductible events in the quarter, had an abnormal effect on the current quarter's tax expense as a percentage of pre-tax income, and therefore impacted net income for the quarter.

**Net income and comprehensive income** 

For the three months ended December 31, 2025, we recorded $0.1 million and $0.5 million of net income and comprehensive income, respectively, compared to $3.5 million and $1.1 million of net income and comprehensive income, respectively, recorded for the same period last year. Comprehensive income includes net income plus other comprehensive income ("OCI") that is not included in net income. Our OCI is comprised of changes in unrealized foreign currency translation gains and losses. Our basic net income per share and diluted net income per share for the current period was $0.00 and $0.00, respectively, compared to basic net income per share and diluted net income per share of $0.13 and $0.13, respectively, for the same period last year.

For the year ended December 31, 2025, we recorded $33.8 million and $44.3 million of net income and comprehensive income, respectively, compared to $44.0 million and $43.3 million of net income and comprehensive income, respectively, recorded for the same period last year. Our basic net income per share and diluted net income per share of $1.18 and $1.14, respectively, compared to basic net income per share and diluted net income per share of $1.64 and $1.51, respectively, for the same period last year.

**Adjusted net (loss) earnings** 

Adjusted net loss for the quarter was $4.3 million, down sharply from earnings of $27.0 million in the prior year. In addition to reported net income decreasing to $0.1 million from $3.5 million, the current quarter also included several non-recurring charges such as Canadian organizational realignment costs, a loss on customer bankruptcy, and an equity investment loss on a customer insolvency settlement. These were only partially offset by a significant non-cash benefit from the change in fair value of contingent obligations. The prior year's quarter benefited from fewer unusual items and a large positive tax effect, resulting in a much higher adjusted net earnings figure.

For the full year, adjusted net earnings declined to $30.4 million from $101.3 million in the prior year. This decrease reflects relatively flat net income, but a higher level of non-recurring and non-cash adjustments in 2025, including losses on derivative instruments, customer bankruptcy, and customer insolvency, as well as realignment and acquisition-related costs. Although the year benefited from a large favorable adjustment to contingent obligations and lower stock-based compensation expense, these were outweighed by the increased one-time charges and less favorable tax effects compared to 2024.

During the fourth quarter of 2025, we excluded three significant items from adjusted earnings as they are considered infrequent and not reflective of ongoing operations. First, our equity consolidated joint venture Nuna recognized a write-down of $8.6 million ($4.3 million at NACG's consolidated level) related to the negotiated settlement of outstanding 2023 change-order claims following notification of a customer's imminent insolvency; this credit-driven event does not reflect current-period execution or core operating results. Second, we wrote off $0.9 million of trade receivables after extended restructuring proceedings yielded no collection progress, and the customer subsequently entered bankruptcy. Given our longstanding history of no credit losses, this bad debt expense is considered non-recurring and not indicative of normal operations. Third, we incurred organizational realignment costs, including $2.0 million of workforce reduction and severance costs and certain facility closure and leadership transition costs, as part of a targeted right-sizing of our Canadian operations in response to lower activity levels; these initiatives are expected to continue through 2026 Q1 but are not anticipated to recur thereafter. Management believes excluding these items enhances period-over-period comparability and provides a clearer depiction of underlying operating performance, and all adjustments are fully reconciled to the most directly comparable GAAP measure in accordance with applicable guidance.

**Summary of consolidated quarterly results** 

A number of factors contribute to variations in our quarterly financial results between periods, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the mix of work from earthworks, with heavy equipment, to more labour intensive, light construction projects;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• seasonal weather and ground conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certain types of work that can only be performed during cold, winter conditions when the ground is frozen;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing and size of capital projects undertaken by our customers on large oil sands projects;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing of equipment maintenance and repairs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing of project ramp-up costs as we move between seasons or types of
projects;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing of resolution for claims and unsigned change-orders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the timing of "mark-to-market" expenses related to the effect of a change in our share price on stock-based compensation plan liabilities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the level of borrowing under our convertible debentures, Credit Facility and finance leases and the corresponding interest
expense recorded against the outstanding balance of each.

Our operations are subject to seasonal variations, primarily influenced by weather patterns and ground conditions that affect both access and equipment utilization across our reportable segments. These seasonal factors have a direct impact on our quarterly revenue, operational planning, and resource allocation, and should be considered when evaluating our financial performance and outlook.

Rental and production-related mine support revenue in the Queensland region can be affected by the annual rainy cyclone season, typically occurring from November to February. During this period, heavy rainfall and flooding can result in temporary suspension of mining activities, leading to reduced utilization of production fleets as equipment is parked for safety reasons. Despite these interruptions, demand for support equipment often increases, as recovery activities such as road clean-up, dewatering, and civil construction are required to restore operational capacity. As weather conditions improve from March onwards, mining activity and equipment utilization generally rebound, supporting a return to normal project execution levels.

Mine support revenue in the oil sands region is traditionally highest during December to March, when frozen ground conditions are optimal for heavy equipment-intensive tasks, including reclamation and muskeg removal. The onset of seasonal thawing from April to June presents operational challenges, resulting in decreased mine support revenue due to limited access and reduced equipment utilization. For other resource mines in Canada, activity typically peaks from May to October, aligning with favorable summer weather that enables increased project execution.

------

The level of project work executed by Nuna in each fiscal quarter is highly seasonal and dependent on both project scope and geographic location. In remote Northern regions of Canada, construction activity is concentrated in the third quarter, coinciding with a short summer season that often lasts less than 14 weeks. Southern projects benefit from longer execution windows, generally from June to October, and are less impacted by extreme seasonality, though spring road bans may still affect operations. Winter road construction and maintenance activities are typically scheduled in the fourth and first quarters, when frozen conditions permit site access.

Seasonal fluctuations in activity and equipment utilization may result in variability in our quarterly financial results. Management actively monitors these patterns and adjusts operational plans and resource deployment to mitigate the impact of adverse weather conditions and optimize performance during peak periods.

As at December 31, 2025, we maintained a strong liquidity position, with cash of $100.1 million and $322.3 million of unused borrowing capacity under our Credit Facility, resulting in total liquidity of $422.4 million (defined as cash plus available and unused Credit Facility borrowings). This represents an increase from December 31, 2024, when cash was $77.9 million and unused Credit Facility availability was $92.7 million, for total liquidity of $170.6 million.

Our liquidity is further supported by additional borrowing capacity through our equipment leasing partners. As at December 31, 2025, total available capital liquidity, which includes total liquidity plus unused finance lease and other borrowing availability under our Credit Facility, was $475.5 million, up from $275.3 million at December 31, 2024. Borrowing availability under finance lease obligations reflects both current and long-term portions, including obligations for joint ventures that we guarantee. There are no restrictions within the terms of our Credit Facility relating to the use of operating leases.

Net working capital (excluding cash and the current portion of long-term debt) was $47.8 million at December 31, 2025, compared to $56.2 million at December 31, 2024. The decrease was primarily due to lower accounts receivable and higher contract liabilities, partially offset by increases in contract assets and inventories.

As at December 31, 2025, trade receivables more than 30 days past due totaled $2.7 million, compared to $1.2 million at December 31, 2024. We did not have an allowance for credit losses related to these receivables in either year, as we continue to assess the risk of collection as minimal. We actively monitor the creditworthiness of our customers.

Working capital assets and liabilities are influenced by the timing of project completions and the contractual terms associated with each project. In certain contracts, customers may withhold a portion of payments, referred to as "holdbacks", as security until specific conditions are met, such as substantial completion of the contract, resolution of any outstanding claims, and the passage of a stipulated period (typically 45 days post-completion). In some cases, we negotiate the progressive release of holdbacks as projects reach various milestones. As at December 31, 2025, holdbacks totaled $3.2 million, compared to $0.8 million at December 31, 2024.

Total assets increased to $1.8 billion at December 31, 2025, from $1.7 billion at December 31, 2024, primarily due to investments in property, plant, and equipment. Net debt was $878.5 million at December 31, 2025, compared to $856.2 million at December 31, 2024, reflecting the issuance of senior unsecured notes and increased equipment financing, partially offset by repayments on the Credit Facility and convertible debentures.

**Capital resources** 

Our capital resources consist primarily of cash flow provided by operating activities, cash borrowings under our Credit Facility and financing through operating leases and capital equipment financing.

Our primary uses of cash include capital expenditures, debt and interest payments, funding operating and finance lease obligations, supporting working capital needs, and paying dividends. Additionally, when appropriate, we have used cash to repurchase our common shares.

We expect that cash generated from operations, together with existing cash balances and available borrowings under our Credit Facility, will be sufficient to fund our annual expenses, planned capital expenditures, and to meet both current and future working capital, debt service, and dividend payment requirements in 2026.

------

Capital additions for the quarter were $44.2 million, a decrease from $77.7 million in the prior year. This reduction was primarily driven by lower purchases of property, plant, and equipment ("PPE"), which were $47.2 million, down from $79.9 million, partially offset by higher proceeds from PPE sales largely related to the 2025 Q4 sale of 797 haul trucks.

For the full year, capital additions totaled $325.0 million, slightly up from $308.5 million in the prior year. While purchases of PPE and net capital expenditures were lower year-over-year, the increase in capital additions was mainly due to higher finance lease additions, which increased to $51.3 million from $14.2 million. This increase allows us to benefit from strong finance lease interest rates and optimize capital investment while preserving liquidity.

During the quarter, Heavy Equipment – Australia saw a significant increase in sustaining capital, up to $42.7 million from $26.7 million in the prior year, while growth capital increased to $35.9 million from $23.6 million, indicating a strategic shift toward expansion. In contrast, Heavy Equipment – Canada's reported net sustaining capital recovery of $34.5 million, compared to spend of $27.3 million in the prior year, primarily due to proceeds from the sale of 797 haul trucks noted above. No growth capital additions were recorded in the segment in either period.

For the full year, Heavy Equipment – Australia's sustaining capital increased to $135.5 million from $93.2 million, while growth capital remained steady at $84.2 million. Heavy Equipment – Canada's sustaining capital decreased to $77.7 million from $130.7 million, and growth capital increased to $27.5 million from just $27.0 thousand, reflecting growth opportunity earlier in the current year.

A portion of our heavy construction fleet is financed through finance leases. We continue to lease our motor vehicle fleet through our finance lease facilities. Our equipment fleet is currently split among owned (82%), finance leased (17%) and rented equipment (1%).

Capital additions within our joint ventures during both the three and twelve month periods were primarily sustaining in nature. In the current quarter and year, Fargo recorded net capital disposals, reflecting the phased sale of equipment as the project progresses toward completion of specific stages. MNALP's capital activity in 2025 Q4 was impacted by the sale of 11 haul trucks, offset by capital additions largely related to routine maintenance of the existing fleet. In 2024, Nuna experienced net capital disposals, primarily due to the sale of surplus equipment following the completion of work in northern Ontario.

For the three months ended December 31, 2025, operating cash flow was $56.2 million, down from $100.6 million in the same quarter of 2024. The decline was mainly due to a large unfavorable swing in non-cash working capital, a negative change in the fair value of contingent obligations, and lower unrealized foreign currency gains. While net income and deferred tax expense were higher, these were not enough to offset the negative impacts from working capital and other non-cash adjustments in the quarter.

For the year ended December 31, 2025, operating cash flow increased to $264.1 million from $241.2 million in 2024. This improvement was primarily driven by higher non-cash depreciation expense and increased deferred tax expense, which more than offset a slight decrease in net income and a negative swing in the fair value of contingent obligations. Improved working capital management also contributed, as the outflow was significantly reduced compared to the prior year.

Cash (used in) provided by the net change in non-cash working capital specific to operating activities are summarized in the table below:

During the three months ended December 31, 2025, net cash used in non-cash working capital was $0.5 million, compared to net cash provided of $34.4 million in the same period of 2024. The primary drivers of the decrease were higher outflows related to accounts payable and contract assets, partially offset by inflows from accounts receivable.

For the year ended December 31, 2025, net cash used in non-cash working capital was $4.7 million, compared to net cash used of $59.4 million in 2024. The improvement year-over-year was mainly due to lower outflows from accounts receivable and accounts payable, offset by higher outflows from contract assets and inventories.

*Investing activities* 

Net cash used in investing activities for the quarter was $33.4 million, a substantial reduction from the $79.3 million used in the same period of 2024. This positive shift was primarily driven by an increase in proceeds from asset disposals, which rose to $5.9 million from $2.5 million in the prior year quarter, reflecting cash proceeds on the sale of 797 haul trucks in the quarter. Additionally, net collections on loans with affiliates and joint ventures increased to $10.2 million, compared to $2.2 million in 2024, further supporting cash flow. Although capital expenditures for the quarter were $47.2 million, slightly lower than the $79.9 million spent in the prior year, indicating a modest reduction in investment pace.

| MANAGEMENT'S DISCUSSION AND ANALYSIS | **33** |

---

------

For the full year, net cash used in investing activities was $264.8 million, representing a decrease from $298.3 million in 2024. The reduction was largely attributable to lower purchases of property, plant and equipment, which decreased to $281.1 million from $303.8 million in the prior year, and net collections from affiliates and joint ventures, which shifted from a $4.1 million outflow in 2024 to a $8.9 million inflow in 2025.

*Financing activities* 

Cash used in financing activities for the quarter was $23.6 million, slightly higher than the $22.4 million used in the same period of 2024. This increase was driven by more active debt management, with proceeds from long-term debt rising to $139.2 million and repayments increasing to $125.3 million, compared to $33.2 million and $28.7 million, respectively, in the prior year. Shareholder returns also grew, as dividend payments totaled $3.4 million and share repurchases under the NCIB reached $12.6 million, up from $4.3 million in 2024. The quarter's results reflect a heightened focus on both capital structure optimization and shareholder value, with increased debt activity and higher capital returns.

Cash provided by financing activities during the year ended December 31, 2025, was $21.6 million, a decrease from $46.0 million in the same period of 2024. The decrease reflects a shift toward shareholder returns and debt service, offset by continued access to long-term financing. The decrease reflects higher debt repayments and increased shareholder distributions, partially offset by strong long-term debt proceeds from refinancing activities completed during the year. Proceeds on long-term debt totalled $757.4 million, up significantly from $234.5 million in 2024, primarily related to the issuance of new senior unsecured notes. Debt repayments increased to $629.7 million compared to $130.3 million in the prior year, as we optimized our debt structure. Dividend payments increased to $13.4 million from $10.6 million, while share repurchases under the NCIB totalled $38.4 million and Treasury share purchases of $3.3 million reflect investment in our employee incentive plans.

**Free cash flow** 

Free cash flow is a non-GAAP measure (see "Explanatory Notes – Non-GAAP Financial Measures" in this MD&A). Below is our reconciliation from the consolidated statement of cash flows ("Cash provided by operating activities" and "Cash used in investing activities") to our definition of free cash flow.

Free cash flow for the three months ended December 31, 2025 was $57.4 million, up from $50.5 million during the same period last year. The current quarter result was primarily driven by adjusted EBITDA of $77.6 million, offset by sustaining capital expenditures of $8.2 million, cash interest payments of $15.3 million, and current income taxes of $5.2 million.

Free cash flow for the year ended December 31, 2025, of $61.2 million is an increase over $18.0 million for the prior year. The current year result was primarily supported by adjusted EBITDA of $356.5 million, with deductions for sustaining capital expenditures of $213.2 million, cash interest payments totaling $56.1 million, and current income taxes of $8.0 million.

<sup>(i)</sup>Operating leases are net of receivables on subleases of $158 (2026 – $158).

<sup>(ii)</sup>Non-lease components of lease commitments are net of receivables on subleases of $4 (2026 – $4). These commitments include common area maintenance, management fees, property taxes and parking related to operating leases.

Our total contractual obligations of $1,194.5 million as at December 31, 2025, have increased from $1,138.1 million as at December 31, 2024, primarily driven by the issuance of $467.5 million in senior unsecured notes and a $56.5 million increase in equipment financing. These increases were partially offset by a $272.8 million reduction in our Credit Facility, a $101.1 million decrease in contingent obligations, a $91.1 million decrease in convertible debentures, and a $0.6 million reduction in supplier contracts. For a discussion on our Credit Facility see "Credit Facility" below and for a more detailed discussion of our convertible debentures, see "Capital Structure and Securities" in our most recent AIF, which section is expressly incorporated by reference into this MD&A.

**Credit Facility** 

On May 1, 2025, we entered into an Amended and Restated Credit Agreement (the "Credit Facility") with a banking syndicate. The amended agreement matures on May 1, 2028, with an option to extend on an annual basis, subject to certain conditions. The agreement is comprised solely of a revolving facility that includes a Canadian dollar tranche of $300.0 million (no change) and an Australian dollar tranche of $250.0 million AUD (no change), totaling $528.9 million of lending capacity using the exchange rate in effect as at December 31, 2025. As at December 31, 2025, the Credit Facility had borrowings of $165.0 million under the Canadian dollar tranche and $10.0 million AUD under the Australian dollar tranche, for total borrowings of $174.2 million using the exchange rate in effect as at December 31, 2025. The Credit Facility permits Senior Unsecured Notes to a limit of $400.0 million, equipment financing to a limit of $400.0 million (no change) and certain other borrowings outstanding to a limit of $20.0 million. The permitted amount of $400.0 million for equipment financing includes guarantees provided by us to certain joint ventures. During the year ended December 31, 2025, financing costs of $0.6 million were incurred in connection with the amended Credit Facility and are recorded as deferred financing costs in other assets on the Consolidated Balance Sheets.

As at December 31, 2025, there was $32.5 million (December 31, 2024 – $34.0 million) in issued letters of credit under the Credit Facility and the unused borrowing availability was $322.3 million (December 31, 2024 – $92.7 million).

As at December 31, 2025, there was an additional $35.6 million in borrowing availability under finance lease obligations (December 31, 2024 – $86.7 million). Borrowing availability under finance lease obligations considers the current and long-term portion of finance lease obligations and financing obligations, including the finance lease obligations for the joint ventures that we guarantee.

| MANAGEMENT'S DISCUSSION AND ANALYSIS | **35** |

---

------

The Credit Facility has three financial covenants that must be tested quarterly on a trailing four-quarter basis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The first covenant is the Senior Debt to Bank EBITDA Ratio.

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Senior Debt" is defined as the sum of the outstanding principal balance (current and long-term portions) of: (i) finance leases; (ii) borrowings under the Company's credit facilities (including outstanding Letters of Credit); (iii) promissory notes; (iv) financing obligations; and (v) guarantees provided for joint ventures. For clarity, Senior Debt excludes vendor financing, convertible debentures and senior unsecured notes.  |

---

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Bank EBITDA" is defined as earnings before interest, taxes, depreciation and amortization, excluding the effects of unrealized foreign exchange gain or loss, realized and unrealized gain or loss on derivative financial instruments, cash and non-cash stock-based compensation expense, gain or loss on disposal of property, plant and equipment, acquisition costs, and certain other non-cash items included in the calculation of net income  |

---

<sup>⚪</sup> The Senior Debt to Bank EBITDA Ratio must be no greater than 3.0:1.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The second covenant is the Total Debt to Bank EBITDA Ratio.

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Total Debt" is defined as the sum of the outstanding principal balance (current and long-term portions) of: (i) finance leases; (ii) borrowings under the Company's credit facilities (including outstanding Letters of Credit); (iii) mortgage; (iv) promissory notes; (v) financing obligations; (vi) vendor financing; (vii) guarantees provided for joint ventures; and (viii) senior unsecured notes. For clarity, Total Debt excludes convertible debentures.  |

---

---

| | |
|:---|:---|
| <sup>⚪</sup> | The Total Debt to Bank EBITDA Ratio must be less than or equal to 4.0:1.  |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The third covenant is the Interest Coverage Ratio which is calculated by dividing Bank EBITDA by cash Interest Expense.

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Interest Expense" is defined as the aggregate amount of interest and other financing charges paid or payable by the Canadian Borrower, on account of such period with respect to Debt, including interest, amortization of discount and financing fees, commissions, discounts, the interest or time value of money component of costs related to factoring or securitizing receivables or monetizing inventory and other fees and charges payable with respect to letters of credit, letters of guarantee and bankers' acceptance financing, standby fees, the interest component of Capital Leases, all as determined in accordance with GAAP.  |

---

<sup>⚪</sup> The Interest Coverage Ratio must be greater than 3.0:1.

As at December 31, 2025, we were in compliance with our financial covenants. The Senior Debt to Bank EBITDA Ratio was 1.61:1, in compliance with the maximum of 3.0:1. The Total Debt to Bank EBITDA Ratio was 2.84:1, in compliance with the maximum of 4.0:1. The Interest Coverage Ratio was 6.46:1, in compliance with the minimum of 3.0:1.

The Credit Facility bears interest at Canadian prime rate, U.S. Dollar Base Rate, Australian Bank Bill Swap Reference Rate ("BBSY"), Canadian bankers' acceptance rate or the Secured Overnight Financing Rate ("SOFR") (all such terms as used or defined in the Credit Facility), plus applicable margins. Based on amounts drawn as at December 31, 2025, the weighted interest rate for the Credit Facility was 5.60% (December 31, 2024 – 6.74%). We are also subject to non-refundable standby fees, 0.40% to 0.75% depending on our Total Debt to Bank EBITDA Ratio. The Credit Facility is secured by a lien on all of our existing and after-acquired property.

**Guarantees** 

We act as a guarantor for drawn amounts under revolving equipment lease credit facilities which have a combined capacity of $115.0 million for MNALP, an affiliate of ours. This equipment lease credit facility allows MNALP to avail the credit through a lease agreement and/or equipment finance contract with appropriate supporting documents. We are the primary operator of MNALP's equipment through the subcontractor agreement. The loan is supported by the pledged equipment and the guarantee is in place in case of a shortfall in an insolvency. As at December 31, 2025, we have provided guarantees on this facility of $57.7 million. At this time, there have been no instances or indication

------

that payments will not be made by MNALP. Therefore, no liability has been recorded. As at December 31, 2025, $37.6 million of the balance of these guarantees was included in the consideration receivable related to the divestiture of 11 Caterpillar 797 (400-ton) haul trucks. These lease liabilities were reassigned on January 29, 2026, at which point they were removed from MNALP financing obligations.

**Senior unsecured notes** 

On May 1, 2025, we completed a private placement of $225.0 million aggregate principal amount of senior unsecured notes due May 1, 2030. On October 22, 2025, we completed an additional private placement of $125.0 million aggregate principal amount as part of the same series as the initial notes, bringing the total outstanding balance to $350.0 million (the "Notes"). The additional offering was issued at a premium of $3.8 million, included within Long-term debt and amortized straight-line through interest expense. The Notes accrue interest at the rate of 7.75% per annum, payable semi-annually in arrears on November 1 and May 1 each year, commencing on November 1, 2025.

The indenture governing the Notes (the "Indenture") contains customary covenants that limit our ability, in certain respects and subject to certain qualifications and exceptions, to incur additional debt, issue preferred stock, make certain payments and investments, create liens, enter into transactions with affiliates, consolidate, merge, or transfer property and assets.

In the event of a change in control, we may be required to offer to repurchase Notes for a cash price equal to at least 101% of the aggregate principal amount of Notes outstanding, plus accrued and unpaid interest.

Prior to May 1, 2027, we may, upon notice to holders, redeem up to 40% of the principal amount of Notes outstanding by payment of a cash redemption price equal to 107.75% of the principal amount of Notes redeemed from the proceeds of an equity offering, or may redeem more than 40% of the principal amount of Notes outstanding by payment of certain higher premiums set out in more detail in the indenture. On or after May 1, 2027, we may redeem all or any part of the Notes, upon notice to the holders, by paying a cash redemption price equal to 103.875% of the principal amount for redemptions in 2027, 101.938% of the principal amount for redemptions in 2028 and 100% of the principal amount for redemptions in 2029 or later. Upon any redemption, we will also pay all accrued and unpaid interest up to the date of redemption.

The Notes are subordinate to the Credit Facility, equipment financing and building mortgage and rank senior to existing convertible debentures.

During the year ended December 31, 2025, we incurred financing costs of $8.9 million relating to the issuance of the Notes. These costs were capitalized as deferred financing costs and are amortized on a straight-line basis over the contractual terms of the Notes, with the amortization recognized to interest expense.

**Outstanding share data** 

*Common shares* 

We are authorized to issue an unlimited number of voting common shares and an unlimited number of non-voting common shares. On June 12, 2014, we entered into a trust agreement whereby the trustee may purchase and hold voting common shares, classified as treasury shares on our Consolidated Balance Sheets, until such time that units issued under the equity classified long-term incentive plans are to be settled. Units granted under such plans typically vest at the end of a three-year term.

As at March 6, 2026, there were 28,517,365 total voting common shares outstanding, which included 876,010 common shares held by the trust and classified as treasury shares on our consolidated balance sheets (28,821,481 common shares, including 871,244 common shares classified as treasury shares at December 31, 2025). We had no non-voting common shares outstanding on any of the foregoing dates.

*Convertible debentures*

------

On January 29, 2025, we issued a notice of redemption to the holders of 5.50% convertible debentures at a redemption price equal to their principal amount, plus accrued and unpaid interest thereon up to, but excluding, the redemption date of February 28, 2025. Holders had the option to convert debentures into common shares of the Company prior to the redemption date at a price of $24.23 per share until the redemption date. Any unconverted debentures were redeemed for $1,008.86 per $1,000 principal, including accrued interest. Between January 29, 2025 and February 28, 2025, holders elected to convert $72.7 million of the outstanding principal amount into 3,002,231 common shares. We paid the remaining balance of $1.4 million in cash and delisted the debentures from the Toronto Stock Exchange. We also derecognized unamortized deferred financing costs of $1.9 million related to these debentures.

The 5.00% convertible debentures were issued March 20, 2019, and mature on March 31, 2026. Interest is payable semi-annually on March 31 and September 30 of each year. The current conversion price is $25.02, and is adjusted upon certain events, including: the subdivision or consolidation of the outstanding common shares, issuance of certain options, rights or warrants, distribution of cash dividends in an amount greater than $0.12 per common share for the 5.00% convertible debentures, and other reorganizations such as amalgamations or mergers. The debentures are redeemable under certain conditions after a change in control has occurred. If a change in control occurs, the Company is required to offer to purchase all of the convertible debentures at a price equal to 101% of the principal amount plus accrued and unpaid interest to the date of purchase. The debentures are otherwise not redeemable by the Company. If any portion of the debentures is required to be settled in cash at maturity or upon a change in control, we intend to fund such payments using availability under its existing credit facility. The remaining unamortized deferred financing costs on the debentures is $0.1 million.

*Share purchase program* 

On November 20, 2025, we commenced a normal course issuer bid ("NCIB") under which a maximum number of 2,729,056 common shares were authorized to be purchased. During the year ended December 31, 2025, we purchased and subsequently cancelled 253,058 shares under this NCIB, which resulted in a decrease to common shares of $2.3 million and a decrease to additional paid-in capital of $2.6 million. To support the NCIB, we entered into an automatic share purchase plan with a designated broker. This plan allows for the purchase of up to 2,729,056 common shares until the NCIB's expiry on November 19, 2026.

Subsequent to the year ended December 31, 2025, as of March 6, 2026, we purchased and subsequently cancelled 407,616 shares under this NCIB, which resulted in a decrease of common shares of $3,655 and an increase to additional paid-in capital of $4,809.

During the year ended December 31, 2025, we completed a NCIB which commenced on November 4, 2024, upon the purchase and cancellation of a total of 1,781,550 common shares, which resulted in a decrease to common shares of $15.7 million and a decrease to additional paid-in capital of $22.2 million.

*Swap Agreement* 

On May 29, 2024, we entered into a swap agreement on its common shares with a financial institution for risk management purposes in relation to its stock-based compensation arrangements. During the year ended December 31, 2025, we recognized an unrealized loss of $9.4 million on this agreement based on the difference between the par value of the shares and the expected price of our shares at contract maturity. The agreement is for 583,725 shares at a par value of $26.73, and an additional 250,000 shares at a par value of $25.10. The agreements mature on May 31, 2027, and September 31, 2027, respectively, with early termination provisions. The TSX closing price of the shares as at December 31, 2025, was $19.76, resulting in a fair value of $5.4 million being recorded to other long-term obligations (note 15) on the Consolidated Balance Sheets. The swap has not been designated as a hedge for accounting purposes and therefore changes in the fair value of the derivative are recognized in the Consolidated Statements of Operations and Comprehensive Income.

During the year ended December 31, 2024, we realized a gain of $0.2 million from a different swap agreement, which had been recorded in the prior year as unrealized. This swap agreement was completed on January 3, 2024, and the derivative financial instrument recorded on the Consolidated Balance Sheets was extinguished at that time.

**Debt ratings** 

On April 24, 2025, our Company received a credit rating from S&P Global Ratings ("S&P") of "BB-" (stable) and from Morningstar DBRS ("Morningstar") of "BB (high)" (stable). On October 7, 2025 and October 24, 2025, respectively, S&P and Morningstar re-confirmed these ratings.

| &nbsp;&nbsp; Combined backlog<sup>(i)</sup> | $**3044947** | $3520773 |

---

<sup>(i)</sup>See "Non-GAAP Financial Measures".

Backlog decreased by $303.2 million while combined backlog decreased by $475.8 million on a net basis, during the year ended December 31, 2025. The decrease was primarily driven by progress on the stream diversion project in Canadian oil sands and an early work and development contract in the Australian state of New South Wales, partially offset by contract expansions in the state of Queensland, Australia.

Revenue generated from backlog during the year ended December 31, 2025, was $1,102.9 million and we estimate that $897.0 million of our backlog reported above will be performed over 2026. For the year ended December 31, 2024, revenue generated from backlog was $1,313.0 million.

**Related parties** 

Accounts payable due to joint ventures and affiliates do not bear interest, are unsecured and without fixed terms of repayment. Accounts receivable from certain joint ventures and affiliates bear interest at various rates, and all other accounts receivable amounts are non-interest bearing. The following table provides the material aggregate outstanding balances with affiliates and joint ventures.

We enter into transactions with a number of our joint ventures and affiliates that involve providing services primarily consisting of subcontractor services, management fees, equipment rental revenue, and sales of equipment and components. These transactions were conducted in the normal course of operations, which were established and agreed to as consideration by the related parties. The vast majority of services provided in the oil sands region are being completed through MNALP. This joint venture performs the role of contractor and sub-contracts work to us. For the years ended December 31, 2025, and 2024, revenue earned from these services was $571.2 million and $560.0 million, respectively. The accounts receivable, contract assets, and accounts payable balances above are primarily from these services with MNALP. Other assets and accrued liabilities relate to loans to and from affiliates, primarily for working capital requirements and advances against future dividends from MNALP and Nuna, including accumulated interest on the loans outstanding.

OUTLOOK

Our operational priorities for 2026 are:

• Safety – maintain a safety-first mentality across all global operations – ensuring EVERYONE GETS HOME SAFE;

• Australian workforce mix – optimize workforce mix in Australia, following the improvements implemented in the second
half of 2025;

ACCOUNTING ESTIMATES, PRONOUNCEMENTS AND MEASURES

**Critical accounting estimates** 

The preparation of our consolidated financial statements in conformity with US GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from these estimates.

Significant estimates and judgments made by us include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the assessment of the percentage of completion on time-and-materials, unit-price, lump-sum and cost-plus contracts with defined scope (including estimated total costs and
provisions for estimated losses) and the recognition of variable revenue from unapproved contract modifications and change orders on contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the determination of whether an acquisition meets the definition of a business combination;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the fair value of the assets acquired and liabilities assumed as part of an acquisition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the evaluation of whether we are a primary beneficiary of an entity or has a controlling interest in an investee and is
required to consolidate it;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assumptions used in measuring the fair value of contingent obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assumptions used in impairment testing; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• estimates and assumptions used in the determination of the allowance for credit losses, the recoverability of deferred tax
assets and the useful lives of property, plant and equipment and intangible assets.

Actual results could differ materially from those estimates.

The accuracy of our revenue and profit recognition in a given period is dependent on the accuracy of the estimates of the cost to complete each project. Cost estimates for all significant projects use a detailed "bottom up" approach and we believe our experience allows us to provide reasonably dependable estimates. There are a number of factors that can contribute to changes in estimates of contract cost and profitability that are recognized in the period in which such adjustments are determined. The most significant of these include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the completeness and accuracy of the original bid;

---

| | |
|:---|:---|
| **40** | NORTH AMERICAN CONSTRUCTION GROUP |

---

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• costs associated with added scope changes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extended overhead due to owner, weather and other delays;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• subcontractor performance issues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in economic indices used for the determination of escalation or de-escalation for contractual rates on long-term contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in productivity expectations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• site conditions that differ from those assumed in the original bid;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contract incentive and penalty provisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability and skill level of workers in the geographic location of the project; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a change in the availability and proximity of equipment and materials.

The foregoing factors as well as the mix of contracts at different margins may cause fluctuations in gross profit between periods. With many projects of varying levels of complexity and size in process at any given time, changes in estimates can offset each other without materially impacting our profitability. Major changes in cost estimates, particularly in larger, more complex projects, can have a significant effect on profitability.

For a complete discussion of how we apply these critical accounting estimates in our significant accounting policies adopted, see the "Significant accounting policies" section of our consolidated financial statements for the year ended December 31, 2025, and notes that follow, which sections are expressly incorporated by reference into this MD&A.

**Change in significant accounting policy – Classification of heavy equipment tires** 

Effective in the first quarter of 2025, we have 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.

**Accounting pronouncements recently adopted** 

*Joint venture formations* 

We adopted the new standard for joint venture formations effective January 1, 2025. In August 2023, the FASB issued ASU 2023-05, Business Combinations – Joint Venture Formations. This accounting standard update was issued to create new requirements for valuing contributions made to a joint venture upon formation. The adoption of this new standard did not have a material impact to the consolidated financial statements.

*Stock compensation* 

We adopted the new standard for stock compensation effective January 1, 2025. In March 2024, the FASB issued ASU 2024-01, Compensation – Stock Compensation. This accounting standard update was issued to reduce complexity in determining if profit interest awards are subject to Topic 718 and to reduce diversity in practice. The adoption of this new standard did not have a material impact to the consolidated financial statements.

*Financial instruments* – *Credit losses* 

We adopted the new standard for credit losses effective July 1, 2025, by electing early adoption. In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses. This accounting standard update allows entities to apply a practical expedient that assumes that conditions as of the balance sheet date do not change for the

remaining life of the asset when estimating expected credit losses of current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. The adoption of this new standard did not have a material impact on the consolidated financial statements.

*Income taxes* 

We adopted the new standard for income taxes effective January 1, 2025. In December 2023, the FASB issued ASU 2023-09, Income Taxes: Improvements to Income Tax Disclosures. This accounting standard update was issued to increase transparency by improving income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. We have updated our disclosures to reflect the additional requirements.

**Recent accounting pronouncements not yet adopted** 

*Debt with conversion options* 

In November 2024, the FASB issued ASU 2024-04, Debt – Debt with Conversion and Other Options. This accounting standard update was issued to improve the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20. This standard is effective for annual statements for the fiscal year beginning January 1, 2026. We are assessing the impact the adoption of this standard may have on its consolidated financial statements.

*Expense disaggregation* 

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures. This accounting standard update was issued to require public entities to disclose additional information about specific expense categories in the notes to financial statements. This standard is effective for annual statements for the fiscal year beginning January 1, 2027. We are assessing the impact the adoption of this standard may have on its consolidated financial statements.

*Intangibles* – *Goodwill and Other* – *Internal-Use Software* 

In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software. This

accounting standard update was issued to modernize the accounting for software costs that are accounted for

under Subtopic 350-40 by making targeted improvements to 350-40 to increase the operability of the recognition

guidance considering different methods of software development. This standard is effective for annual statements

for the fiscal year beginning after December 15, 2027, with early adoption permitted. We are assessing the impact

the adoption of this standard may have on our consolidated financial statements.

**Financial instruments** 

For a complete discussion of our use of financial instruments, see note 16 of our consolidated financial statements for the year ended December 31, 2025.

**Financial measures** 

**Non-GAAP financial measures** 

We believe that the below Non-GAAP financial measures are all meaningful measures of business performance because they include or exclude items that are or are not directly related to the operating performance of our business. Management reviews these measures to determine whether property, plant and equipment are being allocated efficiently.

"Adjusted EBIT" is defined as adjusted net earnings before the effects of interest expense, income taxes and equity earnings in affiliates and joint ventures, but including the equity investment EBIT from our affiliates and joint ventures accounted for using the equity method.

"Adjusted EBITDA" is defined as adjusted EBIT before the effects of depreciation, amortization and equity investment depreciation and amortization.

"Adjusted EPS" is defined as adjusted net earnings, divided by the weighted-average number of common shares.

"Adjusted net earnings" is defined as net income and comprehensive income available to shareholders excluding the effects of unrealized foreign exchange gain or loss, realized and unrealized gain or loss on derivative financial

instruments, cash and non-cash (liability and equity classified) stock-based compensation expense, gain or loss on disposal of property, plant and equipment and certain other non-cash items included in the calculation of net income.

As adjusted EBIT, adjusted EBITDA, adjusted EPS, and adjusted net earnings are non-GAAP financial measures, our computations may vary from others in our industry. These measures should not be considered as alternatives to operating income or net income as measures of operating performance or cash flows and they have important limitations as analytical tools and should not be considered in isolation or as substitutes for analysis of our results as reported under US GAAP. For example, adjusted EBITDA does not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reflect our cash expenditures or requirements for capital expenditures or capital commitments or proceeds from capital
disposals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reflect changes in our cash requirements for our working capital needs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reflect the interest expense or the cash requirements necessary to service interest or principal payments on our debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• include tax payments or recoveries that represent a reduction or increase in cash available to us; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reflect any cash requirements for assets being depreciated and amortized that may have to be replaced in the future.

"Backlog" is a measure of the amount of secured work we have outstanding and, as such, is an indicator of a base level of future revenue potential. We define backlog as work that has a high certainty of being performed as evidenced by the existence of a signed contract or work order specifying expected job scope, value and timing. Backlog, while not a GAAP term is similar in nature and definition to the "transaction price allocated to the remaining performance obligations", defined under US GAAP and reported in "Note 6 – Revenue" in our financial statements. When the two numbers differ, the variance relates to expected scope where we have a contractual commitment, but the customer has not yet provided specific direction.

"Capital additions" is defined as capital expenditures, net and lease additions.

"Capital expenditures, net" is defined as growth capital and sustaining capital. We believe that capital expenditures, net and its components are a meaningful measure to assess resource allocation.

"Capital inventory" is defined as rotatable parts included in property, plant and equipment held for use in the overhaul of property, plant and equipment.

"Cash liquidity" is defined as cash plus available and unused Credit Facility less outstanding letters of credit.

"Cash provided by operating activities prior to change in working capital" is defined as cash used in or provided by operating activities excluding net changes in non-cash working capital.

"Cash related interest expense" is defined as total interest expense less amortization of deferred financing costs and the debt premium on senior unsecured notes.

"Combined backlog" is a measure of the total of backlog from wholly-owned entities plus equity method investment backlog.

"Combined gross profit" is defined as consolidated gross profit per the financial statements combined with our share of gross profit from affiliates and joint ventures that are accounted for using the equity method. This measure is reviewed by management to assess the impact of affiliates and joint ventures' gross profit on our adjusted EBITDA margin.

"Equity investment depreciation and amortization" is defined as our proportionate share (based on ownership interest) of depreciation and amortization in other affiliates and joint ventures accounted for using the equity method.

"Equity investment EBIT" is defined as our proportionate share (based on ownership interest) of equity earnings in affiliates and joint ventures before the effects of gain or loss on disposal of property, plant and equipment, interest expense and income taxes.

"Equity method investment backlog" is a measure of our proportionate share (based on ownership interest) of backlog from affiliates and joint ventures that are accounted for using the equity method.

"Free cash flow" is defined as cash from operations less cash used in investing activities including finance lease additions, non-cash changes in the fair value of contingent obligations, and the effect of exchange rates on the changes in cash but excluding cash used for growth capital and acquisitions. We believe that free cash flow is a relevant measure of cash available to service our debt repayment commitments, pay dividends, fund share purchases and fund both growth capital expenditures and potential strategic initiatives.

"General and administrative expenses (excluding stock-based compensation)" is a measure of general and administrative expenses recorded on the statement of operations less expenses related to stock-based compensation.

"Growth capital", "growth capital additions", and "growth spending" are defined as new or used revenue-generating and customer facing assets which are not intended to replace an existing asset. These expenditures result in a meaningful increase to earnings and cash flow potential.

"Invested capital" is defined as total shareholders' equity plus net debt.

"Net debt" is defined as senior-secured debt plus the sum of the outstanding principal balance(current and long-term portions) of: senior unsecured notes; vendor financing; and convertible debentures less cash recorded on the balance sheets. Net debt is used by us in assessing our debt repayment requirements after using available cash.

"Senior-secured debt" is defined as the sum of the outstanding principal balance (current and long-term portions) of: finance leases; borrowings under our credit facilities (excluding outstanding Letters of Credit); promissory notes; financing obligations; and mortgage debt. We believe senior-secured debt is a meaningful measure in understanding our debt obligations.

"Share of affiliate and joint venture capital additions" is defined as our proportionate share (based on ownership interest) of capital expenditures, net and lease additions from affiliates and joint ventures that are accounted for using the equity method.

"Sustaining capital" is defined as expenditures, net of routine disposals, related to property, plant and equipment which have been commissioned and are available for use operated to maintain and support existing earnings and cash flow potential and do not include the characteristics of growth capital.

"Total capital liquidity" is defined as total liquidity plus unused finance lease and other borrowing availability under our Credit Facility.

"Total combined revenue" is defined as consolidated revenue per the financial statements combined with our share of revenue from affiliates and joint ventures that are accounted for using the equity method. This measure is reviewed by management to assess the impact of affiliates and joint ventures' revenue on our adjusted EBITDA margin.

**Non-GAAP ratios** 

"Margin" is defined as the financial number as a percent of total reported revenue. We will often identify a relevant financial metric as a percentage of revenue and refer to this as a margin for that financial metric.

"Adjusted EBITDA margin" is defined as adjusted EBITDA divided by total combined revenue.

"Combined gross profit margin" is defined as combined gross profit divided by total combined revenue.

We believe that presenting relevant financial metrics as a percentage of revenue is a meaningful measure of our business as it provides the performance of the financial metric in the context of the performance of revenue. Management reviews margins as part of its financial metrics to assess the relative performance of its results.

"Net debt leverage" is calculated as net debt at period end divided by the trailing twelve-month adjusted EBITDA. We believe this provides meaningful information about our ability to repay and service debt held at period end.

**Supplementary financial measures** 

"Gross profit margin" represents gross profit as a percentage of revenue.

"Total net working capital (excluding cash and current portion of long-term debt)" represents net working capital, less the cash and current portion of long-term debt balances.

INTERNAL SYSTEMS AND PROCESSES

**Evaluation of disclosure controls and procedures** 

Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required to disclose is recorded, processed, summarized and reported within the time periods specified under Canadian and US securities laws. They include controls and procedures designed to ensure that information is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer to allow timely decisions regarding required disclosures.

An evaluation was carried out under the supervision of and with the participation of management, including the Chief Executive Officer and the Chief Financial Officer of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the US Securities Exchange Act of 1934, as amended; and in National Instrument 52-109 under the Canadian Securities Administrators Rules and Policies. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2025, such disclosure controls and procedures were effective.

**Management's report on internal control over financial reporting** 

Internal control over financial reporting is a process designed to provide reasonable, but not absolute, assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US GAAP. Management, including the Chief Executive Officer and the Chief Financial Officer are responsible for establishing and maintaining adequate internal control over financial reporting ("ICFR"), as such term is defined in Rule 13a-15(f) and 15d-15(f) under the US Securities Exchange Act of 1934, as amended; and in National Instrument 52-109 under the Canadian Securities Administrators Rules and Policies. A material weakness is a deficiency, or a combination of deficiencies, in ICFR, such that there is reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Because of its inherent limitations, ICFR may not prevent or detect misstatements. Also, projections or any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As of December 31, 2025, we applied the criteria set forth in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") to assess the effectiveness of our ICFR. Based on this assessment, management has concluded that, as of December 31, 2025, our internal control over financial reporting is effective, and the previously identified material weakness in our inventory controls in the MacKellar entities has been remediated as described below.

Our independent auditor, KPMG LLP, has issued an audit report stating that we maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by COSO.

*Remediation of material weakness over inventory* 

As previously reported in our Annual Report for the fiscal year ended December 31, 2024, management identified a material weakness in its internal controls over financial reporting as part of the first time assessment of the effectiveness of ICFR for the MacKellar entities. Specifically, the MacKellar entities did not maintain evidence supporting the performance of controls relating to inventory counts of parts and supplies inventories, due to lack of appropriate training for the individuals conducting the count.

During the year-ended December 31, 2025, management, with oversight of the audit committee of the board of directors, implemented effective internal controls over the MacKellar entities' inventory process. Remediation activities included, but were not limited to, focused training for the individuals conducting the count, continued ERP implementation to fully utilize all modules, and improvements to the control design for effective retention of the evidence to support the performance of the controls. Management has completed testing of its inventory controls and has concluded that the material weakness has been remediated as of December 31, 2025.

FORWARD-LOOKING INFORMATION

Our MD&A is intended to enable readers to gain an understanding of our current results and financial position. To do so, we provide information and analysis comparing results of operations and financial position for the current period to that of the preceding periods. We also provide certain forward-looking information, based on current plans and expectations, for the purpose of assisting the holders of our securities and financial analysts in understanding our financial position and results of operations as at and for the periods ended on the dates presented, as well as our financial performance objectives, vision and strategic goals. Such forward-looking information may not be appropriate for other purposes. Our forward-looking information is subject to known and unknown risks and other factors that may cause future actions, conditions or events to differ materially from the anticipated actions, conditions or events expressed or implied by such forward-looking information. Readers are cautioned that actual events and results may vary materially from the forward-looking information.

Forward-looking information is information that does not relate strictly to historical or current facts and can be identified by the use of the future tense or other forward-looking words such as "anticipate", "believe", "could", "estimate", "expect", "intend", "possible", "predict", "project", "will" or the negative of those terms or other variations of them or comparable terminology.

Examples of such forward-looking information in this document include, but are not limited to, statements with respect to the following, each of which is subject to significant risks and uncertainties and is based on a number of assumptions which may prove to be incorrect:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our belief that there is minimal risk in the collection of past due trade receivables;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our anticipation that we will have enough cash to fund our annual operating expenses, planned capital spending program and
to meet working capital, debt servicing and dividend payment requirements in 2026 from existing cash balances, cash provided by operating activities and borrowings under our Credit Facility;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• calculations of future interest payments that depend on variable rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements regarding backlog, including our expectation that $897.0 million of our backlog will be performed over
2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• statements relating to the acquisition of IMC and generally to our ability to expand our footprint in Australia, including
statements relating to our ability to 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 Australia;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any statements relating to our ability to expand upon and win new work, generally; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all financial guidance provided in the "Outlook" section of this MD&A, including projections related to
combined revenue, Adjusted EBITDA and free cash flow.

While we anticipate that subsequent events and developments may cause our views to change, we do not have an intention to update this forward-looking information, except as required by applicable securities laws. This forward-looking information represents our views as of the date of this document and such information should not be relied upon as representing our views as of any date subsequent to the date of this document. We have attempted to identify important factors that could cause actual results, performance or achievements to vary from those current expectations or estimates expressed or implied by the forward-looking information. However, there may be other factors that cause results, performance or achievements not to be as expected or estimated and that could cause actual results, performance or achievements to differ materially from current expectations.

**There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those expected or estimated in such statements. Accordingly, readers should not place undue reliance on forward-looking information.** 

These factors are not intended to represent a complete list of the factors that could affect us. See "Assumptions" and "Risk Factors" below and risk factors highlighted in materials filed with the securities regulatory authorities filed in the United States and Canada from time to time, including, but not limited to, risk factors that appear in the "Forward-Looking Information, Assumptions and Risk Factors" section of our most recent AIF, which section is expressly incorporated by reference in this MD&A.

**Assumptions** 

The material factors or assumptions used to develop the above forward-looking statements include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continuing demand for heavy construction and earth-moving services, including in diversified resources and geographies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• continuing demand for external heavy equipment maintenance services and our ability to hire and retain sufficient qualified
personnel and to have sufficient maintenance facility capacity to capitalize on that demand;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to maintain our expenses at current levels in proportion to our revenue;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• work continuing to be required under our master services agreements with various customers and such master services
agreements remaining intact;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our customers' continued willingness and ability to meet their contractual obligations to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our customers' continued economic viability, including their ability to pay us in a timely fashion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our customers and potential customers continuing to outsource activities for which we are capable of providing services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• oil and coal prices remaining stable and not dropping significantly in 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• worldwide demand for metallurgical coal remaining stable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• oil sands production continuing to be resilient to drops in oil prices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to source and maintain the right size and mix of equipment in our fleet and to secure specific types of rental
equipment to support project development activity that enables us to meet our customers' variable service requirements while balancing the need to maximize utilization of our own equipment and that our equipment maintenance costs are similar
to our historical experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our continued ability to access sufficient funds to meet our funding requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our success in executing our business strategy, identifying and capitalizing on opportunities, managing our business,
maintaining and growing our relationships with customers, retaining new customers, competing in the bidding process to secure new projects and identifying and implementing improvements in our maintenance and fleet management practices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our relationships with the unions representing certain of our employees continuing to be positive; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our success in improving profitability and continuing to strengthen our balance sheet through a focus on performance,
efficiency and risk management.

**Risk factors** 

The following are the key risk factors that affect us and our business. These factors could materially and adversely affect our operating results and could cause actual results to differ materially from those described in forward-looking statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Customer Insourcing*** . Outsourced heavy construction and mining services constitute a large portion of the work
we perform for our customers. The election by one or more of our customers to perform some or all of these services themselves, rather than outsourcing the work to us, could have a material adverse impact on our business and results of operations.
Certain customers perform some of this work internally and may choose to expand on the use of internal resources to complete this work if they believe they can perform this work in a more cost effective and efficient manner using their internal
resources.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Equipment Utilization*** . Our business depends on our fleet being operable and in ready-to-work condition. We often operate in conditions that inflict a high degree of wear on our equipment. If we are unable to maintain our fleet so as to obtain our
planned utilization rates, or if we are required to expend higher than expected amounts on maintenance or to rent replacement equipment at high rates due to equipment

------

breakdowns, our operating revenues and profits will be adversely impacted. We endeavor to mitigate these risks through our maintenance planning and asset management processes and procedures, though there is no assurance that we can anticipate our future equipment utilization rates with certainty.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Health and Safety*** . Despite our efforts to minimize the risk of safety incidents in carrying out our work,
they can occur from time to time and, if and when they do, the impact on us can be significant. Our success as a company is highly dependent on our ability to keep our work sites and offices safe and any failure to do so can have serious impact on
the personal safety of our employees and others. In addition, it can expose us to contract termination, fines, regulatory sanctions or even criminal prosecution. Our safety record and worksite safety practices also have a direct bearing on our
ability to secure work. Certain clients will not engage contractors to perform work if their safety practices do not conform to predetermined standards or if the contractor has an unacceptably high incidence of safety infractions or incidents. We
adhere to very rigorous health and safety systems and programs which are continually reinforced and monitored on our work sites and offices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Project Management*** . Our business requires effective project management. We are reliant on having skilled
managers to effectively complete our contracted work on time and on budget. Increased costs or reduced revenues due to productivity issues caused by poor management are usually not recoverable and will result in lower profits or potential project
losses. Project managers also rely on our business information systems to provide accurate and timely information in order to make decisions in relation to projects. The failure of such systems to provide accurate and timely information may result
in poor project management decisions and ultimately in lower profits or potential project losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Large Projects and Joint Ventures*** . A portion of our revenue is derived from large projects, some of which are
conducted through joint ventures. These projects provide opportunities for significant revenue and profit contributions but, by their nature, carry significant risk and, as such, can result in significant losses. The risks associated with such
large-scale projects are often proportionate to their size and complexity, thereby placing a premium on risk assessment and project execution. The contract price on large projects is based on cost estimates using several assumptions. Given the size
of these projects, if assumptions prove incorrect, whether due to faulty estimates, unanticipated circumstances, or a failure to properly assess risk, profit may be materially lower than anticipated or, in a worst-case scenario, result in a
significant loss. The recording of the results of large project contracts can distort revenues and earnings on both a quarterly and an annual basis and can, in some cases, make it difficult to compare the financial results between reporting periods.
Joint ventures are often formed to undertake a specific project, jointly controlled by the partners, and are dissolved upon completion of the project. We select our joint venture partners based on a variety of criteria including relevant expertise,
past working relationships, as well as analysis of prospective partners' financial and construction capabilities. Joint venture agreements spread risk between the partners and they generally state that companies will supply their proportionate
share of operating funds and share profits and losses in accordance with specified percentages. Nevertheless, each participant in a joint venture is usually liable to the client for completion of the entire project in the event of a default by any
of its partners. Therefore, in the event that a joint venture partner fails to perform its obligations due to financial or other difficulties or is disallowed from performing or is otherwise unable to perform its obligations as a result of the
client's determination, whether pursuant to the relevant contract or because of modifications to government or agency procurement policies or rules or for any other reason, we may be required to make additional investments or provide
additional services which may reduce or eliminate profit, or even subject us to significant losses with respect to the joint venture. As a result of the complexity and size of such projects that we undertake or are likely to undertake going forward,
the failure of a joint venture partner on a large complex project could have a significant impact on our results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Competition*** . We compete for work with other contractors of various sizes and capabilities. New contract
awards and contract margins are dependent on the level of competition and the general state of the markets in which we operate. Fluctuations in demand may also impact the degree of competition for work. Competitive position is based on a multitude
of factors including pricing, ability to obtain adequate bonding, backlog, financial strength, appetite for risk, reputation for safety, quality, timeliness and experience. If we are unable to effectively respond to these competitive factors,
results of operations and financial condition will be adversely impacted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Cash flow, Liquidity and Debt*** . As of December 31, 2025, we had $918.7 million of debt and
convertible debentures outstanding. While we have achieved a significant improvement in the flexibility to borrow against our borrowing capacity over the past three years, our current indebtedness may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our ability to obtain additional financing to fund our working capital, capital expenditures, debt service
requirements, potential growth or other purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our ability to use operating cash flow in other areas of our business as such funds are instead used to service debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our ability to post surety bonds required by some of our customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• place us at a competitive disadvantage compared to competitors with less debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase our vulnerability to, and reduce our flexibility in planning for, adverse changes in economic, industry and
competitive conditions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase our vulnerability to increases in interest rates because borrowings under our Credit Facility and payments under
our mortgage along with some of our equipment leases and promissory notes are subject to variable interest rates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Further, if we do not have sufficient cash flow to service our debt, we would need to refinance all or part of our existing
debt, sell assets, borrow more money or sell securities, none of which we can guarantee we will be able to achieve on commercially reasonable terms, if at all.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Resolution of Claims*** . Changes to the nature or quantity of the work to be completed under our contracts are
often requested by clients or become necessary due to conditions and circumstances encountered while performing work. Formal written agreement to such changes, or in pricing of the same, is sometimes not finalized until the changes have been started
or completed. As such, disputes regarding the compensation for changes could impact our profitability on a particular project, our ability to recover costs or, in a worst-case scenario, result in project losses. If we are not able to resolve claims
and undertake legal action in respect of these claims, there is no guarantee that a court will rule in our favour. There is also the possibility that we could choose to accept less than the full amount of a claim as a settlement to avoid legal
action. In either such case, a resolution or settlement of the claims in an amount less than the amount recognized as claims revenue could lead to a future write-down of revenue and profit. Included in our revenues is a total of $3.2 million
relating to disputed claims or unapproved change orders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Impact of Extreme Weather Conditions and Natural Disasters*** . Extreme weather conditions or natural disasters,
such as fires, floods and similar events, may cause delays in the progress of our work due to restricted site access or inefficiency of operations due to weather-related ground conditions, which to the extent that such risk is not mitigated through
contractual terms, may result in loss of revenues while certain costs continue to be incurred. Our Australian operations are particularly susceptible to heavy rainfall and flooding from November through to the end of February. Such delays may also
lead to incurring additional non-compensable costs, including overtime work, that are necessary to meet customer schedules. Delays in the commencement of a project due to extreme weather or natural disaster
may also result in customers choosing to defer or even cancel planned projects entirely. Such events may also impact availability and cost of equipment, parts, labour or other inputs to our business that could have a material adverse effect on our
financial position. If the frequency or severity of such events rises in the future as a result of climate change, our risk and potential impacts will also rise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Force Majeure Events*** . We are exposed to various risks arising out of extraordinary or force majeure events
beyond our control, such as epidemics or pandemics, acts of war, terrorism, strikes, protests or social or political unrest generally. Such events could disrupt our operations, result in shortages of materials and equipment, cause supply chain
delays or delivery failures, or lead to the realization of or exacerbate the impact of other risk factors. To the extent that such risks are not mitigated contractually through provisions that provide us with relief from its schedule obligations
and/or cost reimbursement, our financial condition, results of operations or cash flows may be adversely affected. Reliance on global networks and supply chains, rates of international travel and the significant number of people living in
high-density urban environments increase humanity's susceptibility to infectious disease. Epidemics occurring

in regions in which we operate and pandemics that pose a global threat can negatively impact business operations by disrupting the supply chain and causing high absenteeism across the workforce. Similarly, disasters arising from extraordinary or force majeure events may result in disruptions resulting from the evacuation of personnel, cancellation of contracts, or the loss of workforce, contractors or assets. In addition, a disaster may disrupt public and private infrastructure, including communications and financial services, which could disrupt our normal business operations. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Customer Credit Risk*** . Risk of non-payment by our customers is to a
certain degree minimized by statutory lien rights, which give contractors certain priorities in the event of insolvency proceedings, as well as provisions in our contracts that provide for payment as work is completed. However, there is no guarantee
that these measures will in all circumstances mitigate the risk of non-payment by customers and a significant default or bankruptcy by a customer may significantly and adversely impact results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Short-notice Reductions in Work*** . We allocate and mobilize our equipment and hire personnel based on estimated
equipment and service plans supplied by our customers. At the start of each new project, we incur significant start-up costs related to the mobilization and maintenance configuration of our heavy equipment
along with personnel hiring, orientation, training and housing costs for staff ramp-ups and redeployments. We expect to recover these start-up costs over the planned
volumes of the projects we are awarded. Significant reductions in our customer's required equipment and service needs, with short notice, could result in our inability to redeploy our equipment and personnel in a cost-effective manner. In the
past, such short-notice reductions have occurred due to changes in customer production schedules or mine planning or due to unplanned shutdowns of our customers' processing facilities due to events outside our control or the control of our
customers, such as fires, mechanical breakdowns and technology failures. Our ability to maintain revenues and margins may be adversely affected to the extent these events cause reductions in the utilization of equipment and we can no longer recover
our full start-up costs over the reduced volume plan of our customers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Regulatory Approvals and Permits*** . The development of certain projects requires our customers to obtain
regulatory and other permits, licenses and approvals from various governmental licensing bodies. Our customers may not be able to obtain all necessary permits, licenses and approvals required for the development of their projects in a timely manner
or at all. Such delays are generally outside of our control. The major costs associated with such delays are personnel and associated overhead that is designated for the project which cannot be reallocated effectively to other work. If a
customer's project is unable to proceed, it may adversely impact the demand for our services. Customers may also, from time to time, proceed to award us a contract while a permit or license remains pending. Where a customer does not obtain a
permit or license as expected or a permit or license is revoked, the customer's cash flow and project viability may be impacted, which may lead to additional costs or financial loss for us.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Equipment Buy-Out Provisions*** . Certain of our contracts in Australia
provide the client with the option to buy out our owned equipment at predetermined values. While the buy-outs generally provide pricing at market values, they do introduce a longer-term risk of reduced revenue
generation should they be executed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Environmental*** . We are subject to, and comply with, environmental legislation in all of the jurisdictions in
which we operate. We recognize that we must conduct all of our business in such a manner as to both protect and preserve the environment in accordance with this legislation. While we undertake measures at all sites on which we operate to help ensure
compliance with all environmental regulations and conditions of permits and approvals, there is no certainty that a material breach of such regulations, permits or approvals will never occur. Given our long history and the fact that environmental
regulations tend not to have a statute of limitations, there can also be no guarantee that a historical claim may not arise at some point. Management is not aware of any pending environmental legislation that would be likely to have a material
impact on any of our operations, capital expenditure requirements or competitive position, although there can be no guarantee that future legislation will not be proposed and, if implemented, might have an impact on our financial results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Inflation*** . The costs of performing work for our customers can be subject to inflationary pressures,
particularly with respect to the costs of skilled labour and equipment parts. We have price escalation

---

|:---|:---|

------

clauses in most of our contracts that allow us to increase prices as costs rise, but not all of our contracts contain such clauses. Even when our contracts do contain such clauses, the mechanism for adjusting prices may lag the actual cost increases thereby reducing our margins in the short term. Our ability to maintain planned project margins on longer-term contracts is dependent on having contracted price escalators that accurately reflect increases in our costs. Where a contract contains no price escalation clause, we normally factor expected inflation into our pricing. The ability to meet our forecasted profitability is at risk if we do not properly predict future rates of inflation or have contractual provisions that adjust pricing accurately or in a timely manner. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Interest Rates*** . The rate of interest paid on our outstanding debt fluctuates with changes to general prime
interest lending rates. Increases to prime lending rates will, accordingly, adversely affect our profitability at a level that depends on our total outstanding debt.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Foreign Exchange*** . With the revenues and costs of our Australia operations being almost entirely in Australian
dollars, we are exposed to currency fluctuations between the Australian dollar and the Canadian dollar. While those exchange rates have historically remained relatively stable, there is no assurance that will continue. To a lesser degree we are also
exposed to U.S. dollar exchange rates from our operations in the United States as well as when we purchase equipment and spare parts or incur certain general and administrative expenses from U.S. suppliers. These latter exposures are generally of a
short-term nature and the impact of changes in exchange rates has not been significant in the past.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Internal Controls Over Financial Reporting*** . Ineffective internal controls over financial reporting could
result in an increased risk of material misstatements in our financial reporting and public disclosure record. Inadequate controls could also result in system downtime, give rise to litigation or regulatory investigation, fraud or the inability to
continue our business as presently constituted. We have designed and implemented a system of internal controls and a variety of policies and procedures to provide reasonable assurance that material misstatements in the financial reporting and public
disclosures are prevented and detected on a timely basis and that other business risks are mitigated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Availability of Skilled Labour*** . The success of our business depends on our ability to attract and retain
skilled labour. Our industry is faced with a shortage of skilled labour in certain disciplines, particularly in remote locations that require workers to live away from home for extended periods. The resulting competition for labour may limit our
ability to take advantage of opportunities otherwise available or alternatively may impact the profitability of such endeavors on a going forward basis. We believe that our size and industry reputation will help mitigate this risk but there can be
no assurance that we will be successful in identifying, recruiting or retaining a sufficient number of skilled workers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Heavy Equipment Demand*** . As our work mix changes over time, we adjust our fleet to match anticipated future
requirements. This can involve reallocation of equipment to better match fleet requirements of particular sites, but also can involve both purchasing and disposing of heavy equipment. If the global demand for mining, construction and earthworks
services is reduced, we expect that the global demand for the type of heavy equipment used to perform those services would also be reduced. While we may be able to take advantage of reduced demand to purchase certain equipment at lower prices, we
would be adversely impacted to the extent we seek to sell excess equipment. If we are unable to recover our cost base on a sale of excess heavy equipment, we would be required to record an impairment charge which would reduce net income. If it is
determined that market conditions have impaired the valuation of our heavy equipment fleet, we also may be required to record an impairment charge against net income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Unit-price Contracts*** . Approximately 15%, 12% and 40% of our revenue for the years ended December 31,
2025, 2024 and 2023, respectively, was derived from unit-price contracts and, to a lesser degree, lump-sum contracts. Unit-price contracts require us to guarantee the price of the services we provide and
thereby potentially expose us to losses if our estimates of project costs are lower than the actual project costs we incur and contractual relief from the increased costs is not available. The costs we actually incur may be affected by a variety of
factors including those that are beyond our control, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• site conditions differing from those assumed in the original bid;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability and cost of skilled workers;

---

| | |
|:---|:---|
| MANAGEMENT'S DISCUSSION AND ANALYSIS | **51** |

---

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability and proximity of materials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unfavourable weather conditions hindering productivity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• equipment availability and timing differences resulting from project construction not starting on time; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the general coordination of work inherent in all large projects we undertake.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Further, under these contracts any errors in quantity estimates or productivity losses for which contractual relief is not
available, must be absorbed within the price. When we are unable to accurately estimate and adjust for the costs of unit-price contracts, or when we incur unrecoverable cost overruns, the related projects may result in lower margins than anticipated
or may incur losses, which could adversely affect our results of operations, financial condition and cash flow.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Tariffs.*** While U.S. tariffs on Canadian goods and energy do not directly affect us, potential Canadian
retaliatory measures could increase the cost of heavy equipment parts and components. We would seek to mitigate these impacts through alternative sourcing or contractual cost pass-throughs, though recovery may be delayed due to contract mechanisms
normally being triggered by increases in price indexes rather than direct price increases. Tariffs or related measures could also reduce customer spending or result in delayed or cancelled projects, which could have a material adverse effect on our
future earnings and financial position.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Performance of Subcontractors*** . The profitable completion of some contracts depends to a large degree on the
satisfactory performance of subcontractors who complete different elements of the work. If these subcontractors do not perform to accepted standards, we may be required to hire different subcontractors to complete the tasks, which may impact
schedule, add costs to a contract, impact profitability on a specific job and, in certain circumstances, lead to significant losses. A greater incidence or magnitude of default (including cash flow problems) or bankruptcy amongst subcontractors
related to economic conditions could also impact results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Integration of Acquisitions*** . The integration of any acquisition raises a variety of issues including, without
limitation, identification and execution of synergies, elimination of cost duplication, systems integration (including accounting and information technology), execution of the pre-deal business strategy in an
uncertain economic market, development of common corporate culture and values, integration and retention of key staff, retention of current clients as well as a variety of issues that may be specific to us and industry in which we operate. There can
be no assurance that we will maximize or realize the full potential of any of our acquisitions. A failure to successfully integrate acquisitions and execute a combined business plan could materially impact our future financial results. Likewise, a
failure to expand our existing client base and achieve sufficient utilization of the assets acquired could also materially impact our future financial results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Insurance*** . We maintain insurance in order to both satisfy the requirements of our various contracts as well
as a corporate risk management strategy. Failure to secure adequate insurance coverage could lead to uninsured losses or limit our ability to pursue certain contracts, both of which could impact results. Insurance products from time-to-time experience market fluctuations that can impact pricing and availability. Therefore, our senior management, through our insurance advisors, monitor developments in
the insurance markets so that our insurance needs are met. If any of our third-party insurers fail, refuse to renew or revoke coverage or refuse to cover claims, our overall risk exposure could be materially increased. Insurance risk entails
inherent unpredictability that can arise from assuming long-term policy liabilities or from uncertainty of future events. Although we have in the past been able to meet our insurance needs, there can be no assurances that we will be able to secure
all necessary or appropriate insurance on a go-forward basis. Insurance premiums or deductibles may also increase, resulting in higher costs to us.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Commodity Prices*** . Delays, scope reductions and/or cancellations in previously announced or anticipated
projects in the resources and commodities sector could be impacted by a variety of factors, including but not limited to: the prices of commodities; market volatility; the impact of global economic conditions

affecting demand or the worldwide financial markets; cost overruns on announced projects; efforts by owners to contractually shift risk for cost overruns to contractors; fluctuations in the availability of skilled labour; lack of sufficient governmental investment or infrastructure to support growth; the introduction or repeal of climate change or environmentally-focused legislation (such as a carbon tax); negative perception of the mining industry and related potential environmental impact; the need for consent from or consultation with Indigenous peoples impacted by proposed projects; and a shortage of sufficient transportation infrastructure to transport production to major markets. Commodities prices are determined based on world demand, supply, production, speculative activities, and other factors, all of which are beyond our control. Investment decisions by some of our customers are dependent on their outlook on long-term commodity prices. If that outlook is unfavourable it may cause delay, reduction or cancellation of current and future projects. Postponements or cancellations of investment in existing and new projects could have an adverse impact on our business and financial condition. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Customer Concentration*** . Most of our revenue comes from the provision of services to a small number of
customers. If we lose or experience a significant reduction of business or profit from one or more of our significant customers, we may not be able to replace the lost work or income with work or income from other customers. Certain of our long-term
contracts can allow our customers to unilaterally reduce or eliminate the work that we are to perform under the contract. Additionally, certain contracts allow the customer to terminate the contract without cause with minimal or no notice to us. The
loss of or significant reduction in business with one or more of our major customers could have a material adverse effect on our business and results of operations. Our combined revenue from our four largest customers represented approximately 68%
and 72% of our total combined revenue for the years ended December 31, 2025, and 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Labour Disputes*** . The majority of our workforce resides in Canada and Australia. In Canada, the bulk of our
hourly employees are subject to collective bargaining agreements. Any work stoppage resulting from a strike or lockout could have a material adverse effect on our business, financial condition, and results of operations. To minimize this risk, NACG
has a no strike and no lockout provision in our collective agreements. In addition, our customers employ workers under collective bargaining agreements. Any work stoppage or labour disruption experienced by our key customers could significantly
reduce the amount of our services that they need. In Australia, our hourly work force is regulated by the Fair Work Act and Modern Awards agreement with the exception of site where the work force is subject to an enterprise agreement The Modern
Awards agreement outlines the minimum pay rates and conditions of employment for employees. Our Company is legally required to adhere to the terms of the relevant modern award that applies to the industry we work in. Failure to comply with the
provisions of a modern award can result in penalties and legal action. The Modern Awards agreement minimizes the risk of any labour disputes or unrest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Supply Chain*** . The majority of our work depends on mechanical availability and efficient operation of our
heavy equipment. Maintaining such equipment in good operating condition requires many specialized parts and components. If the suppliers of those parts and components are unable to supply the same in a timely manner, or if we experience
unanticipated rates of failure or other quality issues with the same, we may be required to find alternative suppliers. Alternative sources of supply may be more expensive or may not be available at all within required timeframes depending on the
specific parts and components. Failure to obtain parts and components when needed may impact project schedules, add costs to our operations or otherwise impact our profitability due to inefficiencies which could, in certain circumstances, lead to
significant losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Backlog*** . There can be no assurance that the revenues projected in our backlog at any given time will be
realized or, if realized, that they will perform as expected with respect to margin. Project suspensions, terminations or reductions in scope do occur from time to time due to considerations beyond our control and may have a material impact on the
amount of reported backlog with a corresponding impact on future revenues and profitability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Cyber Security and Information Technology Systems*** . We utilize information technology systems for some of the
management and operation of our business and are subject to information technology and system risks, including hardware failure, cyber-attack, security breach and destruction or interruption of our

---

---

------

information technology systems by external or internal sources. Although we have policies, controls and processes in place that are designed to mitigate these risks, an intentional or unintentional breach of our security measures or loss of information could occur and could lead to a number of consequences, including but not limited to: the unavailability, interruption or loss of key systems applications, unauthorized disclosure of material and confidential information and a disruption to our business activities. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, regulatory penalties or other negative consequences. We attempt to prevent breaches through the implementation of various technology-based security measures, contracting consultants and expert third parties, hiring qualified employees to manage our systems, conducting periodic audits and reviewing and updating policies, controls and procedures when appropriate. To date, we have not been subject to a material cyber security breach that has had a serious impact on our business or operations; however, there is a possibility that the measures we take to protect our information technology systems may not be effective in protecting against a significant specific breach in the future. <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Climate Change Related Financial Risks*** . As new climate change measures are introduced or strengthened our
cost of business may increase as we incur expenses related to complying with environmental regulations and policies. We may be required to purchase new or retrofit current equipment to reduce emissions in order to comply with new regulatory
standards or to mitigate the financial impact of carbon taxation. We may also incur costs related to monitoring regulatory trends and implementing adequate compliance processes. Our inability to comply with climate change laws and regulations could
result in penalties or reputational damage that may impair our prospects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Shifting Customer Priorities Related to Climate Change.*** Climate change continues to attract considerable
public and regulatory attention, with greenhouse gas emission regulations becoming more commonplace and stringent. The transition to a lower-carbon economy has the potential to be disruptive to traditional business models and investment strategies.
Government action intended to address climate change may involve both economic instruments such as carbon taxation as well as restrictions on certain sectors such as cap-and-trade schemes. Certain jurisdictions in which we operate impose carbon taxes on significant emitters and there is a possibility of similar taxation in other
jurisdictions in the future. Other government restrictions on certain market sectors could also adversely impact current or potential clients resulting in a reduction of available work and supplies. Our clients may also alter their long-term plans
due to government regulation, changes in policies of investors or lenders or simply due to changes in public perception of their business. This risk can be mitigated to an extent by identifying changing market demands to offset lower demand for some
services with opportunities in others, forming strategic partnerships and pursuing sustainable innovations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Climate Change Related Reputational Risks*** . Investors and other stakeholders worldwide are becoming more
attuned to climate change action and sustainability matters, including the efforts made by issuers to reduce their carbon footprint. Our reputation may be harmed if it is not perceived by our stakeholders to be sincere in our sustainability
commitment and our long-term results may be impacted as a result. In addition, our approach to climate change issues may increasingly influence stakeholders' views of the company in relation to its peers and their investment decisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Foreign Operations*** . We presently operate within Canada, the United States of America and Australia. We may in
the future engage in projects in other jurisdictions. International projects can expose us to risks beyond those typical for our activities in our home market, including without limitation, economic, geopolitical, geotechnical, military,
repatriation of undistributed profits, currency and foreign exchange risks, adoption of new or expansion of existing tariffs and/or taxes or other restrictions, sanctions risk, partner or third-party intermediary misconduct risks, difficulties in
staffing and managing foreign operations, and other risks beyond our control, including the duration and severity of the impact of global economic downturns. We evaluate our exposure to unusual risks inherent in international projects and, where
deemed appropriate in the circumstances, mitigates these risks through specific contract provisions, insurance coverage and financial instruments. However, there are no assurances that such measures would offset or materially reduce the effects of
such risks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•  ***Management*** . Our continued growth and future success depends on our ability to identify, recruit, assimilate
and retain key management, technical, project and business development personnel. There can be no assurance that we will be successful in identifying, recruiting or retaining such personnel.

**Management's Report on Internal Control over Financial Reporting**

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Management conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the criteria set forth in *Internal Control – Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this evaluation, management has concluded that the Company's system of internal control over financial reporting is effective as of December 31, 2025. The details of this evaluation and conclusion are documented in the MD&A.

KPMG LLP, which has audited the consolidated financial statements of the Company for the year ended December 31, 2025, has also issued a report stating its opinion that the Company has maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the criteria established in *Internal Control – Integrated Framework (2013*) issued by the COSO.

**Report of Independent Registered Public Accounting Firm** 

To the Shareholders and Board of Directors of North American Construction Group Ltd.

*Opinion on Internal Control Over Financial Reporting* 

We have audited North American Construction Group Ltd. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control – Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control – Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive income, changes in shareholders' equity, and cash flows for each of the years then ended, and the related notes (collectively, the consolidated financial statements), and our report dated March 11, 2026 expressed an unqualified opinion on those consolidated financial statements.

*Basis for Opinion* 

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying internal control over financial reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

*Definition and Limitations of Internal Control Over Financial Reporting* 

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We have audited the accompanying consolidated balance sheets of North American Construction Group Ltd. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive income, changes in shareholders' equity, and cash flows for each of the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and its results of operations and its cash flows for each of the years then ended, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control – Integrated Framework (2013)* issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 11, 2026 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

*Change in Accounting Principle* 

As discussed in Note 2(a)(i) to the consolidated financial statements, the Company has elected to change its method of accounting for the classification of heavy equipment tires as of January 1, 2025.

*Basis for Opinion* 

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

*Critical Audit Matters* 

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Estimation of total costs to be incurred for in-progress unit-price contracts with defined scope* 

As discussed in note 2(c) to the consolidated financial statements, the Company recognizes revenues from construction services under lump-sum, unit-price, time-and-materials, and cost-plus contracts. As discussed in Note 6 to the consolidated financial statements, total contract revenues recognized by the Company on unit-price contracts for the year ended December 31, 2025 were $187.8 million, a portion of which related to contracts with defined scope that were in-progress at year-end. Unit-price contracts are typically satisfied by transferring control over time, for which the Company recognizes revenue using the percentage of completion method, measured by the ratio of costs incurred to date to estimated total costs (ETC).

We identified the evaluation of ETC for in-progress unit-price contracts with defined scope as a critical audit matter. The evaluation of the ETC for in-progress unit-price contracts with defined scope involved complex auditor judgement, given these estimates are dependent upon a number of factors, including completeness and accuracy of the original bid, changes in productivity expectations, site conditions that differ from those assumed in the original bid, costs associated with added scope changes, and extended costs due to owner, weather and other delays.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the revenue recognition process. This included controls related to the Company's review of new contracts, the Company's forecast review to assess reasonability of the ETC for unit-price contracts with defined scope that were in-progress at year-end, and the Company's look-forward analysis to re-assess reasonability of ETC for these same contracts after year-end. For a selection of these contracts, we performed substantive procedures to assess the accuracy of the estimates made at year-end, including for key factors related to labour hours, equipment usage, and material costs and quantities to be incurred over the remaining contract periods. For each selected contract, we evaluated the reasonableness of the Company's ETC for the contract, including tracing a selection of costs in the ETC (material costs and quantities, labor hours, and equipment usage) to recent forecasts developed by project managers and comparing actual costs incurred subsequent to year-end for consistency with corresponding amounts included in the ETC at year-end. We evaluated the ETC by inspecting, for the same selection of contracts, the executed contract with the customer to evaluate the Company's identification of the performance obligation and the determined method for measuring contract progress. We conducted interviews with relevant project personnel to gain an understanding of the status of project activities and factors impacting the ETC of the selected contract, such as costs associated with scope changes; extended overhead due to owner, weather, and other delays; changes in productivity expectations; site conditions that differ from those assumed in the original bid; and contract incentive and penalty provisions. We evaluated the Company's ability to estimate these amounts by comparing actual project margins to previous estimates.

Notes to Consolidated Financial Statements

For the years ended December 31, 2025 and 2024

(Expressed in thousands of Canadian Dollars, except per share amounts or unless otherwise specified)

**1. Nature of operations** 

North American Construction Group Ltd. ("NACG" or the "Company"), was formed under the Canada Business Corporations Act. The Company and its predecessors have been operating continuously since 1953 providing a wide range of mining and heavy construction services to customers in the resource development and industrial construction sectors.

**2. Significant accounting policies** 

**a) Basis of presentation** 

These consolidated financial statements are prepared in accordance with United States generally accepted accounting principles ("US GAAP"). These consolidated financial statements include the accounts of the Company and its wholly-owned incorporated subsidiaries in Canada, the United States and Australia. All significant intercompany transactions and balances are eliminated upon consolidation. The Company also holds ownership interests in other corporations, partnerships and joint ventures.

The Company consolidates variable interest entities ("VIE") for which it is considered to be the primary beneficiary as well as voting interest entities in which it has a controlling financial interest as defined by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 810, Consolidation, and related standards. Investees and joint ventures over which the Company exercises significant influence are accounted for using the equity method and are included in "investments in affiliates and joint ventures" within the accompanying Consolidated Balance Sheets.

*i) Change in significant accounting policy – Classification of heavy equipment tires* 

During the first quarter of 2025, the Company changed its 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.

The Company has accounted for the change retrospectively in accordance with the requirements of US GAAP Accounting Standards Codification ("ASC") 250 by restating the comparative period. For details of retrospective changes, refer to note 24 in these consolidated financial statements.

**b) Use of estimates** 

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures reported in these consolidated financial statements and accompanying notes and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Significant estimates and judgments made by management include:

• the assessment of the percentage of completion on time-and-materials, unit-price, lump-sum and cost-plus contracts with defined scope (including estimated total costs and
provisions for estimated losses) and the recognition of variable revenue from unapproved contract modifications and change orders on revenue contracts;

• the determination of whether an acquisition meets the definition of a business combination;

• the fair value of the assets acquired and liabilities assumed as part of an acquisition;

• the evaluation of whether the Company is a primary beneficiary of an entity or has a controlling interest in an investee
and is required to consolidate it;

• assumptions used in measuring the fair value of contingent obligations;

• assumptions used in impairment testing; and

• estimates and assumptions used in the determination of the allowance for credit losses, the recoverability of deferred tax
assets and the useful lives of property, plant and equipment and intangible assets.

The accuracy of the Company's revenue and profit recognition in a given period is dependent on the accuracy of the estimates of the cost to complete each project. Cost estimates for significant projects are estimated using a detailed cost analysis of project activities and the Company believes its experience allows it to provide reasonably dependable estimates. There are a number of factors that can contribute to changes in estimates of contract costs and profitability that are recognized in the period in which such adjustments are determined. The most significant of these include:

• the completeness and accuracy of the original bid;

• revenues and costs associated with added scope changes;

• extended costs due to owner, weather and other delays;

• subcontractor performance issues;

• changes in economic indices used for the determination of escalation or de-escalation for contractual rates on long-term contracts;

• changes in productivity expectations;

• site conditions that differ from those assumed in the original bid;

• contract incentive and penalty provisions;

• the availability and skill level of workers in the geographic location of the project; and

• a change in the availability and proximity of equipment and materials.

The foregoing factors as well as the mix of contracts at different margins may cause fluctuations in gross profit between periods. Major changes in cost estimates, particularly in larger, more complex projects, can have a significant effect on profitability.

**c) Revenue recognition** 

The Company's revenue source falls into one of three categories: construction services, operations support, or equipment and component sales.

Construction services are related to mine development or expansion projects and are generally funded from customers' capital budgets. The Company provides construction services under lump-sum, unit-price, time-and materials and cost-plus contracts. When the commercial terms are lump-sum and unit-price, the contract scope and value is typically defined. Time-and-materials and cost-plus contracts are generally undefined in scope and total price. Operations support services revenue is mainly generated under long-term site-services agreements with the customers (master service agreement and multiple use contracts). These agreements clearly define whether commitment to volume or scope of services over the life of the contract is included or excluded. When excluded, work under the agreement is awarded through shorter-term work authorizations under the general terms of the agreement. The Company generally provides operations support services under either time-and-materials or unit-price contracts depending on factors such as the degree of complexity, the completeness of engineering and the required schedule. Equipment and component sales revenue is generated from equipment maintenance and rebuild activities. The commercial terms for equipment and component sales are generally lump-sum, unit-price, or time-and-materials.

Significant estimates are required in the revenue recognition process including assessment of the percentage of completion, identification of performance obligations, and estimation of variable consideration, including the extent of any constraints.

The Company's invoicing frequency and payment terms are in accordance with negotiated customer contracts. Customer invoicing can range between daily and monthly and payment terms generally range between net 15 and net 60 days. The Company does not typically include extended payment terms in its contracts with customers. Under these payment terms, the customer pays progress payments based on actual work or milestones completed. When payment terms do not align with revenue recognition, the variance is recorded to either contract liabilities or contract assets, as appropriate. Customer contracts do not generally include a significant financing component because the Company does not expect the period between customer payment and transfer of control to exceed one year. The Company does not adjust consideration for the effects of a significant financing component if the period of time between the transfer of control and the customer payment is less than one year.

The Company accounts for a contract when it has approval and commitments from both parties, the rights of the parties are identified, the payment terms are identified, the contract has commercial substance, and the collectability of consideration is probable. Each contract is evaluated to determine if it includes more than one performance obligation. This evaluation requires significant judgement and the determination that the contract contains more than one performance obligation could change the amount of revenue and profit recorded in a given period. The majority of the Company's contracts with defined scope include one significant integrated service, where the Company is responsible for ensuring the individual goods and services are incorporated into one combined output. Such contracts are accounted for as one performance obligation. When more than one distinct good or service is contracted, the contract is separated into more than one performance obligation and the total transaction price is allocated to each performance obligation based upon stand-alone selling prices. When a stand-alone selling price is not observable, it is estimated using a suitable method.

The total transaction price can be comprised of fixed consideration and variable consideration, such as profit incentives, discounts and performance bonuses or penalties. When a contract includes variable consideration, the amount included in the total transaction price is based on the expected value or the most likely amount, constrained to an amount for which it is probable a significant reversal will not occur. Significant judgement is involved in determining if a variable consideration amount should be constrained. In applying this constraint, the Company considers both the likelihood of a revenue reversal arising from an uncertain future event and the magnitude of the revenue reversal if the uncertain event were to occur or fail to occur. The following circumstances are considered to be possible indicators of significant revenue reversals:

• The amount of consideration is highly susceptible to factors outside the Company's influence, such as judgement of
actions of third parties and weather conditions;

• The length of time between the recognition of revenue and the expected resolution;

• The Company's experience with similar circumstances and similar customers, specifically when such items have
predictive value;

• The Company's history of resolution and whether that resolution includes price concessions or changing payment terms;
and

• The range of possible consideration amounts.

The Company's performance obligations for construction services and operations support are typically satisfied by transferring control over time, for which revenue is recognized using the percentage of completion method, measured by the ratio of costs incurred to date to estimated total costs. For defined scope contracts, the cost-to-cost method faithfully depicts the Company's performance because the transfer of the asset to the customer occurs as costs are incurred. The costs of items that do not relate to the performance obligation, particularly in the early stages of the contract, are excluded from costs incurred to date. Pre-construction activities, such as mobilization and site setup, are recognized as contract costs on the Consolidated Balance Sheets and amortized over the life of the project. These costs are excluded from the cost-to-cost calculation. Equipment and component sales are typically satisfied at a point in time, and revenue is recognized when control of the completed asset has been transferred to the customer, along with the cost of goods sold (cost of sales).

The Company has elected to apply the 'as-invoiced' practical expedient to recognize revenue in the amount to which the Company has a right to invoice for all contracts in which the value of the performance completed to date directly corresponds with the right to consideration. This will be applied to all contracts, where applicable, and the majority of undefined scope work is expected to use this practical expedient.

The length of the Company's contracts varies from less than one year for typical contracts to several years for certain larger contracts. Cost of sales include all direct labour, material, subcontract and equipment costs and those indirect costs related to contract performance such as indirect labour and supplies. General and administrative expenses are charged to expenses as incurred. If a loss is estimated on an uncompleted contract, a provision is made in the period in which such losses are determined.

Changes in project performance, project conditions, and estimated profitability, including those arising from profit incentives, penalty provisions and final contract settlements, may result in revisions to costs and revenue that are recognized in the period in which such adjustments are determined. Once a project is underway, the Company will often experience changes in conditions, client requirements, specifications, designs, materials and work schedules. Generally, a "change order" will be negotiated with the customer to modify the original contract to approve both the scope and price of the change. Occasionally, disagreements arise regarding changes, their nature, measurement, timing and other characteristics that impact costs and revenue under the contract. When a change becomes a point of dispute between the Company and a customer, the Company will assess the legal enforceability of the change to determine if an unapproved contract modification exists. The Company considers a contract modification to exist when the modification either creates new or changes the existing enforceable rights and obligations.

Most contract modifications are for goods and services that are not distinct from the existing contract due to the integrated services provided in the context of the contract and are accounted for as part of the existing contract. Therefore, the effect of a contract modification on the transaction price and the Company's measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue on a cumulative catch-up basis. If a contract modification is not approved by the customer, the associated revenue is treated as variable consideration, subject to constraint. Management estimates variable consideration utilizing estimation methods that best predict the amount of consideration to which the Company will be entitled. This can lead to a situation where costs are recognized in one period and revenue is recognized when customer agreement is obtained or claim resolution occurs, which can be in subsequent periods.

In certain instances, the Company's long-term contracts allow its customers to unilaterally reduce or eliminate scope of work without cause. These instances represent higher risk due to uncertainty of total contract value and estimated costs to complete; therefore, potentially impacting revenue recognition in future periods.

Revenue is measured based on consideration specified in the customer contract, and excludes any amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specified revenue producing transaction, that are collected by the Company for a customer, are excluded from revenue.

**d) Balance sheet classifications** 

A one-year time period is typically used as the basis for classifying current assets and liabilities. However, there is a possibility that amounts receivable and payable under construction contracts (principally customer and supplier holdbacks) may extend beyond one year.

**e) Cash** 

Cash includes cash on hand and bank balances net of outstanding cheques.

**f) Accounts receivable and contract assets** 

Accounts receivable are recorded when the Company has an unconditional right to consideration arising from performance of contracts with customers. Accounts receivable may be comprised of amounts billed to customers and amounts that have been earned but have not yet been billed. Such unbilled but earned amounts generally arise when a billing period ends subsequent to the end of the reporting period. When this occurs, revenue equal to the earned and unbilled amount is accrued. Such accruals are classified as accounts receivable on the balance sheet, even though they are not yet billed, as they represent consideration for work that has been completed prior to the period end where the Company has an unconditional right to consideration.

Contract assets include unbilled amounts representing revenue recognized from work performed where the Company does not yet have an unconditional right to compensation. These balances generally relate to (i) revenue accruals on contracts where the percentage of completion method of revenue recognition requires an accrual over what has been billed and (ii) revenue recognized from variable consideration related to unpriced contract modifications.

The Company records allowance for credit losses using the expected credit loss model upon the initial recognition of financial assets. The estimate of expected credit loss considers historical credit loss information that is adjusted for current economic and credit conditions. Bad debt expense is charged to general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income in the period the allowance is recognized. The counterparties to the majority of the Company's financial assets are major oil and coal producers with a long history of no credit losses.

Holdbacks represent amounts up to 10% of the contract value under certain contracts that the customer is contractually entitled to withhold until completion of the project or until certain project milestones are achieved. Information about the Company's exposure to credit risks and impairment losses for trade and other receivables is included in note 16(f).

**g) Contract costs** 

The Company occasionally incurs costs to obtain contracts (reimbursable bid costs) and to fulfill contracts (fulfillment costs). If these costs meet certain criteria, they are capitalized as contract costs, included within other assets on the Consolidated Balance Sheets. Capitalized costs are amortized based on the transfer of goods or services to which the assets relate and are included in cost of sales. Reimbursable bid costs meet the criteria for capitalization when these costs will be reimbursed by the owner regardless of the outcome of the bid. Generally, this occurs when the Company has been selected as the preferred bidder for a project. The Company recognizes reimbursable bid costs as an expense when incurred if the amortization period of the asset that the entity would have otherwise recognized is one year or less. Costs to fulfill a contract meet the criteria for capitalization if they relate directly to a specifically identifiable contract, they generate or enhance resources that will be used to satisfy future performance obligations and if the costs are expected to be recovered. The costs that meet this criterion are often mobilization and site set-up costs. Contract costs are recorded within other assets on the Consolidated Balance Sheets.

**h) Remaining performance obligations** 

Remaining performance obligations represents the transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period. Certain of the Company's long-term contracts can allow customers to unilaterally reduce or eliminate the scope of the contracted work without cause. These long-term contracts represent higher risk due to uncertainty of total contract value and estimated costs to complete; therefore, potentially impacting revenue recognition in future periods. Excluded from this disclosure are amounts where the Company recognizes revenue as-invoiced (note 6(d)).

**i) Contract liabilities** 

Contract liabilities consist of advance payments and billings in excess of costs incurred and estimated earnings on uncompleted contracts. Long-term contract liabilities (included in other long-term obligations) consists of upfront receipts from clients for long-term contracts.

**j) Inventories** 

Inventories are carried at the lower of cost and net realizable value, and consist primarily of repair parts, parts and components held for resale, tires and track frames, fuel and lubricants, and customer rebuild work in progress. Cost is determined using the weighted-average method.

**k) Property, plant and equipment** 

Property, plant and equipment are recorded at cost. Equipment under finance lease is recorded at the present value of minimum lease payments at the inception of the lease.

Major components of heavy construction equipment in use such as engines and drive trains are recorded separately. Depreciation is not recorded until an asset is in use. Depreciation is calculated based on the cost, net of the estimated residual value, over the estimated useful life of the assets on the following bases and rates:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; Assets | Basis | Rate |
| &nbsp;&nbsp; Heavy equipment | Units of production | 5,000 – 120,000 hours |
| &nbsp;&nbsp; Major component parts in use | Units of production | 2,500 – 70,000 hours |
| &nbsp;&nbsp; Other equipment | Straight-line | 5 – 10 years |
| &nbsp;&nbsp; Licensed motor vehicles | Straight-line | 5 – 10 years |
| &nbsp;&nbsp; Office and computer equipment | Straight-line | 4 – 10 years |
| &nbsp;&nbsp; Furnishings, fixtures and facilities | Straight-line | 10 – 30 years |
| &nbsp;&nbsp; Buildings | Straight-line | 10 – 50 years |
| &nbsp;&nbsp; Leasehold improvements | Straight-line | Over shorter of estimated useful life and lease term |
| &nbsp;&nbsp; Land | No depreciation | No depreciation |

---

The costs for periodic repairs and maintenance are expensed to the extent the expenditures serve only to restore the assets to their normal operating condition without enhancing their service potential or extending their useful lives.

**l) Goodwill** 

Goodwill represents the excess of consideration over the fair value of the net tangible and identifiable intangible assets acquired and liabilities assumed in a business combination. Goodwill is reviewed annually on October 1<sup>st</sup> for impairment or more frequently when there is an indication of potential impairment. Impairment is tested at the reporting unit level by comparing the reporting unit's carrying amount to its fair value. The process of determining fair values is subjective and requires management to exercise judgment in making assumptions about future results, including revenue and cash flow projections and discount rates. The annual test was performed on the acquired goodwill with no impairment identified. The carrying amount of Goodwill can fluctuate due to changes in foreign exchange rates impacting the balances recorded within entities using a currency other than CAD. Goodwill is recorded within other assets on the Consolidated Balance Sheets.

**m) Intangible assets** 

Acquired intangible assets with finite lives are recorded at historical cost net of accumulated amortization and accumulated impairment losses, if any. The cost of intangible assets acquired in an asset acquisition are recorded at cost based upon relative fair value as at the acquisition date. Costs incurred to increase the future benefit of intangible assets are capitalized.

Intangible assets with definite lives are amortized over their estimated useful lives and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and method for an intangible asset with a finite useful life are reviewed at the end of each reporting period.

Estimated useful lives of definite lived intangible assets and corresponding amortization method are:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp; Assets | Basis | Rate |
| &nbsp;&nbsp; Internal-use software | Straight-line | 4 years |
| &nbsp;&nbsp; Customer relationship | Straight-line | 4 years |

---

**n) Impairment of long-lived assets** 

Long-lived assets or asset groups held and used including property, plant and equipment and identifiable intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of an asset or group of assets is less than its carrying amount, it is considered to be impaired. The Company measures the impairment loss as the amount by which the carrying amount of the asset or group of assets exceeds its fair value, which is charged to the Consolidated Statements of Operations and Comprehensive Income. In determining whether an impairment exists, the Company makes assumptions about

---

| | |
|:---|:---|
| **70** | NORTH AMERICAN CONSTRUCTION GROUP |

---

------

the future cash flows expected from the use of its long-lived assets, such as: applicable industry performance and prospects; general business and economic conditions that prevail and are expected to prevail; expected growth; maintaining its customer base; and achieving cost reductions. There can be no assurance that expected future cash flows will be realized or will be sufficient to recover the carrying amount of long-lived assets. Furthermore, the process of determining fair values is subjective and requires management to exercise judgment in making assumptions about future results, including revenue and cash flow projections and discount rates.

At each reporting period, the Company reviews the carrying value of its long-lived assets for indications of impairment. At December 31, 2025, there was an impairment indicator identified, for the long-lived assets of the Heavy Equipment - Canada segment. A recoverability test was performed which concluded that the value of the long-lived assets recorded on the balance sheet is not impaired.

**o) Assets held for sale** 

Long-lived assets are classified as held for sale when certain criteria are met, which include:

• management, having the authority to approve the action, commits to a plan to sell the assets;

• the assets are available for immediate sale in their present condition;

• an active program to locate buyers and other actions to sell the assets have been initiated;

• the sale of the assets is probable and their transfer is expected to qualify for recognition as a completed sale within one
year;

• the assets are being actively marketed at reasonable prices in relation to their fair value; and

• it is unlikely that significant changes will be made to the plan to sell the assets or that the plan will be withdrawn.

Assets to be disposed of by sale are reported at the lower of their carrying amount or estimated fair value less costs to sell and are disclosed separately on the Consolidated Balance Sheets. These assets are not depreciated.

Equipment disposal decisions are made using an approach in which a target life is set for each type of equipment. The target life is based on the manufacturer's recommendations and the Company's past experience in the various operating environments. Once a piece of equipment reaches its target life it is evaluated to determine if disposal is warranted based on its expected operating cost and reliability in its current state. If the expected operating cost exceeds the target operating cost for the fleet or if the expected reliability is lower than the target reliability of the fleet, the unit is considered for disposal. Expected operating costs and reliability are based on the past history of the unit and experience in the various operating environments. Once the Company has determined that the equipment will be disposed, and the criteria for assets held for sale are met, the unit is recorded in assets held for sale at the lower of depreciated cost or net realizable value.

**p) Foreign currency translation** 

The functional currency of the Company is Canadian Dollars. Transactions recorded within these subsidiaries that are denominated in foreign currencies are recorded at the rate of exchange on the transaction date. Monetary assets and liabilities within these subsidiaries denominated in foreign currencies are translated into Canadian Dollars at the rate of exchange prevailing at the balance sheet date. The resulting foreign exchange gains and losses are included in the determination of earnings and included within general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income.

Accounts of the Company's Australia-based subsidiaries, which have Australian Dollar functional currency, and US-based subsidiaries, which have US Dollar functional currency, are translated into Canadian Dollars using the current rate method. Assets and liabilities are translated at the rate of exchange in effect at the balance sheet date, and revenue and expense items are translated at the average rate of exchange for the period. The resulting unrealized exchange gains and losses from these translation adjustments are included as a separate component of shareholders' equity in Accumulated Other Comprehensive Income. The effect of exchange rate changes on cash balances held in foreign currencies is separately reported as part of the reconciliation of the change in cash and for the period.

**q) Fair value measurement** 

Fair value measurements are categorized using a valuation hierarchy for disclosure of the inputs used to measure fair value, which prioritizes the inputs into three broad levels. Fair values included in Level 1 are determined by

---

| | |
|:---|:---|
| CONSOLIDATED FINANCIAL STATEMENTS | **71** |

---

------

reference to quoted prices in active markets for identical assets and liabilities. Fair values included in Level 2 include valuations using inputs based on observable market data, either directly or indirectly other than the quoted prices. Level 3 valuations are based on inputs that are not based on observable market data. The classification of a fair value within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Transfers between levels of the fair value hierarchy are deemed to have occurred at the date the event or change in circumstance causing the transfer occurred.

**r) Income taxes** 

The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rates is recognized in income in the period of enactment. A valuation allowance is recorded against any deferred tax asset if it is more likely than not that the asset will not be realized.

The Company recognizes the effect of income tax positions only if those positions are more likely than not (greater than 50%) of being sustained. Changes in recognition or measurement are reflected in the period in which the change in judgement occurs. The Company accrues interest and penalties for uncertain tax positions in the period in which these uncertainties are identified. Interest and penalties are included in general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income.

**s) Stock-based compensation** 

The Company has a Restricted Share Unit ("RSU") Plan which is described in note 21(a). RSUs are generally granted effective July 1 of each fiscal year with respect to services to be provided in that fiscal year and the following two fiscal years. The RSUs generally vest at the end of the three-year term. The Company settles RSUs with common shares purchased on the open market through a trust arrangement. Employees have the option to receive the full amount of vested units or to have the Company withhold shares to satisfy the tax withholding requirements on their behalf. Compensation expense is calculated based on the number of vested RSUs multiplied by the fair value of each RSU as determined by the volume weighted-average trading price of the Company's common shares for the five trading days immediately preceding the day on which the fair market value was to be determined. The Company recognizes compensation cost over the three-year term in the Consolidated Statements of Operations and Comprehensive Income, with a corresponding increase to additional paid-in capital. When dividends are paid on common shares, additional dividend equivalent RSUs are granted to all RSU holders as of the dividend payment date. The number of additional RSUs to be granted is determined by multiplying the dividend payment per common share by the number of outstanding RSUs, divided by the fair market value of the Company's common shares on the dividend payment date. Such additional RSUs are granted subject to the same service criteria as the underlying RSUs.

The Company has a Performance Restricted Share Unit ("PSU") plan which is described in note 21(b). The PSUs vest at the end of a three-year term and are subject to the performance criteria approved by the Human Resources and Compensation Committee at the date of the grant. Such performance criteria include the passage of time and, for awards prior to 2022, is based upon the improvement of total shareholder return ("TSR") as compared to a defined Canadian company peer group. For awards in 2022 and later, performance is based equally on four criteria: (a) improvement of TSR as compared to a defined group consisting of Canadian and US public companies and relevant S&P/TSX small-cap subset indexes; (b) adjusted earnings before interest and taxes; (c) free cash flow; and (d) adjusted return on invested capital. TSR is calculated using the fair market values of voting common shares at the grant date, the fair market value of voting common shares at the vesting date and the total dividends declared and paid throughout the vesting period. The grants are measured at fair value on the grant date using a Monte Carlo model. The Company settles all PSUs with common shares purchased on the open market through a trust arrangement. Employees have the option to receive the full amount of vested units or to have the Company withhold shares to satisfy the tax withholding requirements on their behalf. The Company recognizes compensation cost over the three-year term of the PSU in the Consolidated Statements of Operations and Comprehensive Income, with a corresponding increase to additional paid-in capital.

The Company has a Deferred Stock Unit ("DSU") Plan which is described in note 21(c). The DSU plan enables directors and executives to receive all or a portion of their annual fee or annual executive bonus compensation in the form of DSUs and are settled in cash. The DSUs vest immediately upon issuance and are only redeemable upon departure, retirement or death of the participant. Compensation expense is calculated based on the number of DSUs multiplied by the fair market value of each DSU as determined by the volume weighted-average trading price of the Company's common shares for the 5 trading days immediately preceding the day on which the fair market value is to be determined, with any changes in fair value recognized in general and administrative expenses in the Consolidated Statements of Operations and Comprehensive Income. DSUs are liability classified and are revalued at the end of every reporting period. Compensation costs related to DSUs are recognized in full upon the grant date as the units vest immediately. When dividends are paid on common shares, additional dividend equivalent DSUs are granted to all DSU holders as of the dividend payment date. The number of additional DSUs to be granted is determined by multiplying the dividend payment per common share by the number of outstanding DSUs, divided by the fair market value of the Company's common shares on the dividend payment date. Such additional DSUs are granted subject to the same service criteria as the underlying DSUs.

As stock-based compensation expense recognized in the Consolidated Statements of Operations and Comprehensive Income is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimated.

**t) Net income per share** 

Basic net income per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period (see note 17(b)). Diluted net income per share is computed by dividing net income available to common shareholders by the weighted-average number of shares outstanding during the year, adjusted for dilutive share amounts. The diluted per share amounts are calculated using the treasury stock method and the if-converted method.

**u) Leases** 

For lessee accounting, the Company determines whether a contract is or contains a lease at inception of the contract. At the lease commencement date, the Company recognizes a right-of-use ("ROU") asset and a lease liability. The ROU asset for operating and finance leases are included in operating lease right-of-use assets and property, plant and equipment, respectively, on the Consolidated Balance Sheets. The lease liability for operating and finance leases are included in operating lease liabilities and long-term debt, respectively.

Operating and finance lease assets and liabilities are initially measured at the present value of lease payments at the commencement date. Subsequently, finance lease liabilities are measured at amortized cost using the effective interest rate method and operating lease liabilities are measured at the present value of unpaid lease payments.

As most of the Company's operating lease contracts do not provide the implicit interest rate, nor can the implicit interest rate be readily determined, the Company uses its incremental borrowing rate as the discount rate for determining the present value of lease payments. The Company's incremental borrowing rate for a lease is the rate that the Company would pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Company uses the lease implicit interest rate when it is determinable.

The lease term for all of the Company's leases includes the non-cancellable period of the lease plus any period covered by options to extend (or not to terminate) the lease term when it is reasonably certain that the Company will exercise that option.

Lease payments are comprised of fixed payments owed over the lease term and the exercise price of a purchase option if the Company is reasonably certain to exercise the option. The ROU assets for both operating and finance leases are initially measured at cost, which consists of the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred, less any lease incentives received. For finance leases, ROU asset depreciation expense is recognized and presented separately from interest expense on the lease liability through depreciation and interest expense, net, respectively. The ROU asset for operating leases is measured at the amortized value of the ROU asset. For operating leases, amortization of the ROU asset is calculated as the current-period lease cost adjusted by the lease liability accretion to the then

|:---|:---|
| CONSOLIDATED FINANCIAL STATEMENTS | **73** |

------

outstanding lease balance. Lease expense of the operating lease ROU asset is recognized on a straight-line basis over the remaining lease term through general and administrative expenses.

ROU assets for operating and finance leases are reduced by any accumulated impairment losses. The Company's existing accounting policy for impairment of long-lived assets is applied to determine whether an ROU asset is impaired, and if so, the amount of the impairment loss to be recognized.

The Company monitors for events or changes in circumstances that require a reassessment of one or more of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset.

The Company generally accounts for contracts with lease and non-lease components separately. This involves allocating the consideration in the contract to the lease and non-lease components based on each component's relative standalone price. For certain leases, the Company has elected to apply the practical expedient to account for the lease and non-lease components together as a single lease component. Non-lease components include common area maintenance and machine maintenance. For those leases, the lease payments used to measure the lease liability include all of the fixed consideration in the contract.

ROU assets and lease liabilities for all leases that have a lease term of 12 months or less ("short-term leases") are not recognized. The Company recognizes its short-term lease payments as an expense on a straight-line basis over the lease term. Short-term lease variable payments are recognized in the period in which the payment is assessed.

For lessor accounting, the Company entered into contracts to sublease certain operating property leases to third parties and generally accounts for lease and non-lease components of subleases separately. For certain operating leases of heavy equipment, the Company has elected to apply the practical expedient to account for lease and non-lease components together as a single lease component. Non-lease components for operating leases of heavy equipment include machine maintenance.

If any of the following criteria are met, the Company classifies the lease as a sales-type lease:

• The lease transfers ownership of the underlying asset to the lessee by the end of the lease term;

• The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise;

• The lease term is for the major part of the remaining economic life of the underlying asset. However, if the commencement
date falls at or near the end of the economic life of the underlying asset, this criterion shall not be used for purposes of classifying the lease;

• The present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already
reflected in the lease payments equals or exceeds substantially all of the fair value of the underlying asset.

• The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the
end of the lease term.

When none of these criteria are met, the Company classifies the lease as an operating lease unless both of the following criteria are met, in which case the Company records the lease as a direct financing lease:

• The present value of the sum of the lease payments and any residual value guaranteed by the lessee that is not already
reflected in the lease payments and/or any other third party unrelated to the lessor equals or exceeds substantially all of the fair value of the underlying asset.

• It is probable that the lessor will collect the lease payments plus any amount necessary to satisfy a residual value
guarantee.

For sales-type leases, the Company recognizes the net investment in the lease, and derecognizes the underlying asset on the Consolidated Balance Sheets. The interest income over the lease term is recognized in the Consolidated Statements of Operations and Comprehensive Income, with cash received from leases classified as operating cash flows

in the Consolidated Statements of Cash Flows. The difference between the cash received from leases and the interest income is the reduction of the initial net investment. The net investment at the end of the lease term will equate to the estimated residual value at lease inception. For operating leases, the Company continues to recognize the underlying

asset on the Consolidated Balance Sheets, and lease income is recognized in revenue, straight-line over the lease term in the Consolidated Statements of Operations and Comprehensive Income. The cash received from leases are classified as operating cash flows on the Consolidated Statements of Cash Flows.

**v) Deferred financing costs** 

Underwriting, legal and other direct costs incurred in connection with the issuance of debt are presented as deferred financing costs. Deferred financing costs related to the mortgage and the issuance of Convertible Debentures are included within liabilities on the Consolidated Balance Sheets and are amortized using the effective interest method over the term to maturity. When Convertible Debentures are converted before maturity, the remaining balance of deferred financing costs are recognized in the capital accounts to reflect the shares issued. Deferred financing costs related to revolving facilities under the credit facilities are included within other assets on the Consolidated Balance Sheets and are amortized ratably over the term of the Credit Facility.

**w) Investments in affiliates and joint ventures** 

Upon inception or acquisition of a contractual agreement, the Company performs an assessment to determine whether the arrangement contains a variable interest in a legal entity and whether that legal entity is a variable interest entity ("VIE"). Where it is concluded that the Company is the primary beneficiary of a VIE, the Company will consolidate the accounts of that VIE. Other qualitative factors that are considered include decision-making responsibilities, the VIE capital structure, risk and rewards sharing, contractual agreements with the VIE, voting rights and level of involvement of other parties. The Company assesses the primary beneficiary determination for a VIE on an ongoing basis as changes occur in the facts and circumstances related to a VIE. If an entity is determined not to be a VIE, the voting interest entity model will be applied. The maximum exposure to loss as a result of involvement with the VIE is the Company's share of the investee's net assets.

The Company utilizes the equity method to account for its interests in affiliates and joint ventures that the Company does not control but over which it exerts significant influence. The equity method is typically used when it has an ownership interest of between 15% and 50% in an entity, provided the Company is able to exercise significant influence over the investee's operations. Significant influence is the power to participate in the financial and operating policy decisions of the investee.

Under the equity method, the investment in an affiliate or a joint venture is initially recognized at cost. Transaction costs that are incremental and directly attributable to the investment in the affiliate or joint venture are included in the cost. The total initial cost of the investment is attributable to the net assets in the equity investee at fair value.

The carrying amount of investment is adjusted to recognize changes in the Company's share of net assets of the affiliate or joint venture since the acquisition date.

The aggregate of the Company's share of profit or loss of affiliates and joint ventures is shown on the face of the Consolidated Statements of Operations and Comprehensive Income, representing profit or loss in the subsidiaries of the affiliate or joint venture. This share of profit or loss is inclusive of any mark-to-market adjustments made by the affiliates or joint ventures. Transactions between the Company and the affiliate or joint venture are eliminated to the extent of the interest in the affiliate or joint venture. When the Company earns revenue on downstream sales to affiliate or joint ventures, it eliminates its proportionate share of profit through equity earnings in affiliates and JVs.

After application of the equity method, the Company determines whether it is necessary to recognize an impairment loss on its investment in its affiliate or joint venture. At each reporting date, the Company determines whether there is objective evidence that the investment in the affiliate or joint venture is impaired. If there is such evidence, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value, and then recognizes the loss within "equity earnings in affiliates and joint ventures" in the Consolidated Statements of Operations and Comprehensive Income. Upon loss of significant influence over the associate or joint control over the joint venture, the Company measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate or joint venture upon loss of significant influence or joint control and the fair value of the retained investment and proceeds from disposal is recognized in the Consolidated Statements of Operations and Comprehensive Income.

**x) Derivative instruments** 

The Company may periodically use derivative financial instruments to manage financial risks from fluctuations in share prices. Such instruments are only used for risk management purposes. Derivative financial instruments are subject to standard terms and conditions, financial controls, management and risk monitoring procedures including Board approval for all significant transactions. These derivative financial instruments were not designated as hedges for accounting purposes and were recorded at fair value with realized and unrealized gains and losses recognized in the Consolidated Statements of Operations and Comprehensive Income.

**y) Business combinations** 

Business combinations are accounted for using the acquisition method. Assets acquired and liabilities assumed are recorded at the acquisition date at their fair values. The Company measures goodwill as the excess of the total cost of acquisition over the fair value of identifiable net assets of an acquired business at the acquisition date. Any contingent consideration payable is recognized at fair value at the acquisition date. Any subsequent changes to fair value are recognized in the Consolidated Statement of Operations and Comprehensive Income.

On December 1, 2025, the Company entered into an agreement to dispose of 15 heavy equipment units in Canada and $3,834 of related inventory. The terms of this deal consisted of a cash payment of $1,800, the buyer's acceptance of the outstanding financing liabilities associated with the assets, and the acquisition of 7 heavy equipment units with a value of $34,000. This sale was recognized in the financial statements for the year ending December 31, 2025, except for the reassignment of the financing liabilities, which was completed on January 29, 2026. As of December 31, 2025, the Company's Consolidated Balance Sheets reflected $16,564 in contract assets resulting from this transaction, along with $17,305 recorded under the current portion of long-term debt relating to the financing obligations assignments.

The aggregate maturities of long-term debt for each of the five years subsequent to December 31, 2025, are: $160.5 million in 2026, $85.6 million in 2027, $237.3 million in 2028, $47.7 million in 2029 and $384.0 million in 2030 and thereafter.

**a) Senior unsecured notes** 

On May 1, 2025, the Company completed an initial private placement of $225.0 million aggregate principal amount of senior unsecured notes due May 1, 2030. On October 22, 2025, the Company completed an additional private placement of $125.0 million aggregate principal amount as part of the same series as the initial notes, bringing the total outstanding balance to $350.0 million (the "Notes"). The additional offering was issued at a premium of $3.8 million, included within Long-term debt and amortized straight-line through interest expense. The Notes accrue interest at the rate of 7.75% per annum, payable semi-annually in arrears on November 1 and May 1 each year, commencing on November 1, 2025.

The indenture governing the Notes (the "Indenture") contains customary covenants that limit the Company's ability, in certain respects and subject to certain qualifications and exceptions, to incur additional debt, issue preferred stock, make certain payments and investments, create liens, enter into transactions with affiliates, consolidate, merge, or transfer property and assets.

In the event of a change in control of the Company, the Company may be required to offer to repurchase Notes for a cash price equal to at least 101% of the aggregate principal amount of Notes outstanding, plus accrued and unpaid interest.

Prior to May 1, 2027, the Company may, upon notice to holders, redeem up to 40% of the principal amount of Notes outstanding by payment of a cash redemption price equal to 107.75% of the principal amount of Notes redeemed from the proceeds of an equity offering, or may redeem more than 40% of the principal amount of Notes outstanding by payment of certain higher premiums set out in more detail in the Indenture. On or after May 1, 2027, the

Company may redeem all or any part of the Notes, upon notice to the holders, by paying a cash redemption price equal to 103.875% of the principal amount for redemptions in 2027, 101.938% of the principal amount for redemptions in 2028 and 100% of the principal amount for redemptions in 2029 or later. Upon any redemption, the Company will also pay all accrued and unpaid interest up to the date of redemption.

The Notes are subordinate to the Company's Credit Facility, equipment financing and building mortgage and rank senior to existing convertible debentures.

During the year ended December 31, 2025, the Company incurred financing costs of $8,949 relating to the issuance of the Notes. These costs were capitalized as deferred financing costs and are amortized on a straight-line basis over the contractual terms of the Notes, with the amortization recognized to interest expense.

**c) Financing obligations** 

During the year ended December 31, 2025, the Company entered into $109,531 of new financing obligations. These obligations are secured by the corresponding property, plant and equipment and require monthly payments over the contract term. The annual interest rates on the new obligations ranged from 4.32% to 6.98%, with maturities extending through 2030.

During the year ended December 31, 2024, the Company entered into $114,930 of new financing obligations. These obligations are secured by the corresponding property, plant and equipment and require monthly payments over the contract term. The annual interest rates on the new obligations ranged from 5.56% to 7.92%, with maturities extending through 2029.

Subsequent to December 31, 2025, $17,305 recorded under the current portion of long-term debt relating to the financing obligations assignments were removed upon reassignment on January 29, 2026 (note 8).

**d) Credit Facility** 

On May 1, 2025, the Company entered into an Amended and Restated Credit Agreement (the "Credit Facility") with a banking syndicate. The amended agreement matures on May 1, 2028, with an option to extend on an annual basis, subject to certain conditions. The agreement is comprised solely of a revolving facility that includes a Canadian dollar tranche of $300.0 million and an Australian dollar tranche of $250.0 million AUD, totaling $528.9 million of lending capacity using the exchange rate in effect as at December 31, 2025. As at December 31, 2025, the Credit Facility had borrowings of $165.0 million under the Canadian dollar tranche and $10.0 million AUD under the Australian dollar tranche, for total borrowings of $174.2 million using the exchange rate in effect as at December 31, 2025. The Credit Facility permits Senior Unsecured Notes to a limit of $400.0 million, equipment financing to a limit of $400.0 million and certain other borrowings outstanding to a limit of $20.0 million. The permitted amount of $400.0 million for equipment financing includes guarantees provided by the Company to certain joint ventures. During the year ended December 31, 2025, financing costs of $0.6 million were incurred in connection with the amended Credit Facility and are recorded as deferred financing costs in other assets on the Consolidated Balance Sheets.

------

As at December 31, 2025, there was $32.5 million (December 31, 2024 – $34.0 million) in issued letters of credit under the Credit Facility and the unused borrowing availability was $322.3 million (December 31, 2024 – $92.7 million).

As at December 31, 2025, there was an additional $35.6 million in borrowing availability under finance lease obligations (December 31, 2024 – $86.7 million). Borrowing availability under finance lease obligations considers the current and long-term portion of finance lease obligations and financing obligations, including the finance lease obligations for the joint ventures that the Company guarantees.

The Credit Facility has three financial covenants that must be tested quarterly on a trailing four-quarter basis. As at December 31, 2025, the Company was in compliance with its financial covenants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The first covenant is the Senior Debt to Bank EBITDA Ratio

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Senior Debt" is defined as the sum of the outstanding principal balance (current and long-term portions) of: (i) finance leases; (ii) borrowings under the Company's credit facilities (including outstanding Letters of Credit); (iii) promissory notes; (iv) financing obligations; and (v) guarantees provided for joint ventures. For clarity, Senior Debt excludes vendor financing, convertible debentures and senior unsecured notes.  |

---

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Bank EBITDA" is defined as earnings before interest, taxes, depreciation and amortization, excluding the effects of unrealized foreign exchange gain or loss, realized and unrealized gain or loss on derivative financial instruments, cash and non-cash stock-based compensation expense, gain or loss on disposal of property, plant and equipment, acquisition costs, and certain other non-cash items included in the calculation of net income.  |

---

<sup>⚪</sup> The Senior Debt to Bank EBITDA Ratio must be no greater than 3.0:1.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The second covenant is the Total Debt to Bank EBITDA Ratio.

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Total Debt" is defined as the sum of the outstanding principal balance (current and long-term portions) of: (i) finance leases; (ii) borrowings under the Company's credit facilities (including outstanding Letters of Credit); (iii) mortgage; (iv) promissory notes; (v) financing obligations; (vi) vendor financing; (vii) guarantees provided for joint ventures; and (viii) senior unsecured notes. For clarity, Total Debt excludes convertible debentures.  |

---

---

| | |
|:---|:---|
| <sup>⚪</sup> | The Total Debt to Bank EBITDA Ratio must be less than or equal to 4.0:1.  |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The third covenant is the Interest Coverage Ratio which is calculated by dividing Bank EBITDA by cash Interest Expense.

---

| | |
|:---|:---|
| <sup>⚪</sup> | "Interest Expense" is defined as the aggregate amount of interest and other financing charges paid or payable by the Canadian Borrower, on account of such period with respect to Debt, including interest, amortization of discount and financing fees, commissions, discounts, the interest or time value of money component of costs related to factoring or securitizing receivables or monetizing inventory and other fees and charges payable with respect to letters of credit, letters of guarantee and bankers' acceptance financing, standby fees, the interest component of Capital Leases, all as determined in accordance with GAAP.  |

---

<sup>⚪</sup> The Interest Coverage Ratio must be greater than 3.0:1.

The Credit Facility bears interest at Canadian prime rate, U.S. Dollar Base Rate, Australian Bank Bill Swap Reference Rate ("BBSY"), Canadian bankers' acceptance rate or the Secured Overnight Financing Rate ("SOFR") (all such terms as used or defined in the Credit Facility), plus applicable margins. Based on amounts drawn as at December 31, 2025, the weighted interest rate for the Credit Facility was 5.60% (December 31, 2024 – 6.74%). The Company is also subject to non-refundable standby fees of 0.40% to 0.75%, depending on the Company's Total Debt to Bank EBITDA Ratio. The Credit Facility is secured by a lien on all of the Company's existing and after-acquired property.

The Company acts as a guarantor for drawn amounts under revolving equipment lease credit facilities which have a combined capacity of $115.0 million for Mikisew North American Limited Partnership ("MNALP"), an affiliate of the

------

Company. This equipment lease credit facility will allow MNALP to avail the credit through a lease agreement and/or equipment finance contract with appropriate supporting documents. As at December 31, 2025, the Company has provided guarantees on this facility of $57.7 million (December 31, 2024 – $61.7 million). The Company is only liable for any shortfall that might exist in the event of a default if proceeds from the sale of the underlying assets are insufficient to cover amounts owing. At this time, there have been no instances or indication that payments will not be made by MNALP and, therefore, no liability has been recorded related to this guarantee. As at December 31, 2025, $37.6 million of the balance of these guarantees was included in the consideration receivable related to the divestiture of the Caterpillar 797 (400-ton) haul trucks and were reassigned on January 29, 2026.

**e) Convertible debentures** 

---

| &nbsp;&nbsp; 5.00% convertible debentures | **55000** | 55000 |
|  | $**55000** | $129106 |

---

On January 29, 2025, the Company issued a notice of redemption to the holders of 5.50% convertible debentures at a redemption price equal to their principal amount, plus accrued and unpaid interest thereon up to, but excluding, the redemption date of February 28, 2025. Holders had the option to convert debentures into common shares of the Company prior to the redemption date at a price of $24.23 per share until the redemption date. Any unconverted debentures were redeemed for $1,008.86 per $1,000 principal, including accrued interest. Between January 29, 2025, and February 28, 2025, holders elected to convert $72,749 of the outstanding principal amount into 3,002,231 common shares. The Company paid the remaining balance of $1,357 in cash and delisted the debentures from the Toronto Stock Exchange. The Company also derecognized unamortized deferred financing costs of $1,912 related to these debentures.

The 5.00% convertible debentures were issued March 20, 2019, and mature on March 31, 2026. Interest is payable semi-annually on March 31 and September 30 of each year. The current conversion price is $25.02, and is adjusted upon certain events, including: the subdivision or consolidation of the outstanding common shares, issuance of certain options, rights or warrants, distribution of cash dividends in an amount greater than $0.12 per common share for the 5.00% convertible debentures, and other reorganizations such as amalgamations or mergers. The debentures are redeemable under certain conditions after a change in control has occurred. If a change in control occurs, the Company is required to offer to purchase all of the convertible debentures at a price equal to 101% of the principal amount plus accrued and unpaid interest to the date of purchase. The debentures are otherwise not redeemable by the Company. The remaining unamortized deferred financing costs on the debentures is $80.

**f) Mortgage** 

The mortgage has a maturity date of November 1, 2046, and bears variable interest at a floating base rate of 5.60% minus a variance of 2.20%, equal to 3.40%. The mortgage is secured by the corresponding land and building in Acheson, Alberta.

**16. Financial instruments and risk management** 

**a) Fair value measurements** 

In determining the fair value of financial instruments, the Company uses a variety of methods and assumptions that are based on market conditions and risks existing on each reporting date. Standard market conventions and techniques, such as discounted cash flow analysis, are used to determine the fair value of the Company's financial instruments. All methods of fair value measurement result in a general approximation of fair value.

The fair values of the Company's cash, accounts receivable, accounts payable, and accrued liabilities approximate their carrying amounts due to the nature of the instrument or the relatively short periods to maturity for the instruments. The Credit Facility has a carrying value that approximates the fair value due to the floating rate nature of the debt. The promissory notes have a carrying value that is not materially different than their fair value due to similar instruments bearing similar interest rates.

Financial instruments with carrying amounts that differ from their fair values are as follows:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
|  | | **December 31, 2025** | **December 31, 2025** | December 31, 2024 | December 31, 2024 |
|  | Fair Value<br>Hierarchy Level | **Carrying**<br> **Amount** | **Fair**<br> **Value** | Carrying<br> Amount | Fair<br> Value |
| &nbsp;&nbsp; Senior unsecured notes | Level 2 | **353587** | **360062** |  |  |
| &nbsp;&nbsp; Financing obligations | Level 2 | **225294** | **224003** | 197018 | 196240 |
| &nbsp;&nbsp; Convertible debentures | Level 1 | **55000** | **55330** | 129106 | 168949 |
| &nbsp;&nbsp; Mortgage | Level 2 | **26742** | **24194** | 27600 | 23993 |

---

The Company classifies contingent obligations related to contingent consideration on the MacKellar acquisition, comprised of a contingent payment, deferred consideration and earn-out payments, as Level 3 due to the lack of relevant observable market data over fair value inputs. The contingent obligation is measured at fair value by discounting estimated future payments to the net present value using Level 3 inputs. The Company believes the discount rates used to discount the components of the contingent obligation reflect market participant assumptions.

The contingent payment is based on forecasted performance for a specific MacKellar customer which is expected to be paid in full. The deferred consideration is a MacKellar vendor-provided debt mechanism to be paid out evenly over four years. The determination of the fair value of the contingent consideration related to the earn-out amount required the Company to make significant estimates and assumptions, including estimating the future forecasted net income of MacKellar and the determination of the discount rate. The estimated liability is based on forecasted information and as such, could result in a range of outcomes. The impact of a reasonably possible change of +/-10% in forecasted net income on the fair value of the earn-out obligation is estimated to be between a $4,583 decrease to a $4,583 increase on the fair value as at December 31, 2025. During the year ended December 31, 2025, there has been no change in the valuation approach or technique.

Reconciliation of Level 3 recurring fair value measurements:

---

| | | |
|:---|:---|:---|
|  | **December 31,<br>2025** | December 31,<br>2024 |
| &nbsp;&nbsp; Balance, beginning of period | $**127866** | $115857 |
| &nbsp;&nbsp; Changes in fair value recognized in earnings | **(26909)** | 53206 |
| &nbsp;&nbsp; Changes in foreign exchange rates | **2677** | (1508) |
| &nbsp;&nbsp; Payments | **(40181)** | (39689) |
| &nbsp;&nbsp; Balance, end of the period | $**63453** | $127866 |

---

Changes in the fair value of the contingent obligation are due to adjustments in forecasted income estimates and interest accretion expense and are recorded in the Consolidated Statements of Operations and Comprehensive Income. The revised estimates for the year ended December 31, 2025, reflect a downward adjustment to forecasted performance, offset by interest accretion of the period.

**b) Swap agreement** 

On May 29, 2024, the Company entered into a swap agreement on its common shares with a financial institution for risk management purposes in relation to its stock-based compensation arrangements. During the year ended

---

| | |
|:---|:---|
| CONSOLIDATED FINANCIAL STATEMENTS | **89** |

---

------

December 31, 2025, the Company recognized an unrealized loss of $9,354 on this agreement based on the difference between the par value of the shares and the expected price of the Company's shares at contract maturity. The agreement is for 583,725 shares at a par value of 26.73, and an additional 250,000 shares at a par value of $25.10. The agreements mature on May 31, 2027, and September 31, 2027, respectively, with early termination provisions. The TSX closing price of the shares as at December 31, 2025, was $19.76, resulting in a fair value of $5,402 being recorded to other long-term obligations (note 15) on the Consolidated Balance Sheets (December 31, 2024 – $3,952 in other assets (note 11)). The swap has not been designated as a hedge for accounting purposes and therefore changes in the fair value of the derivative are recognized in the Consolidated Statements of Operations and Comprehensive Income.

During the year ended December 31, 2024, the Company realized a gain of $229 from a different swap agreement, which had been recorded in the prior year as unrealized. This swap agreement was completed on January 3, 2024, and the derivative financial instrument recorded on the Consolidated Balance Sheets was extinguished at that time.

**c) Risk management** 

The Company is exposed to liquidity, market and credit risks associated with its financial instruments. The Company will from time to time use various financial instruments to reduce market risk exposures from changes in foreign currency exchange rates and interest rates. Management performs a risk assessment on a continual basis to help ensure that all significant risks related to the Company and its operations have been reviewed and assessed to reflect changes in market conditions and the Company's operating activities.

The credit worthiness of new customers is subject to review by management through consideration of the type of customer and the size of the contract. The Company has mitigated this risk through diversification of its operations, primarily through investments in joint ventures and recent Australian acquisitions.

**d) Liquidity risk** 

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company manages this risk by monitoring and reviewing actual and forecasted cash flows and the effect on bank covenants. The Company meets its liquidity needs from various sources including cash generated by operating activities, cash borrowings under the Credit Facility and financing through operating and financing leases and capital equipment financing. The Company has unused borrowing availability of $322.3 million on the Credit Facility (December 31, 2024 – $92.7 million) and an additional $35.6 million in borrowing availability under finance lease obligations (December 31, 2024 – $86.7 million). The Company believes that it has sufficient cash balances and availability under the Credit Facility to meet its foreseeable operating requirements.

**e) Market risk** 

Market risk is the risk that the future revenue or operating expense related cash flows, the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices such as foreign currency exchange rates and interest rates. The level of market risk to which the Company is exposed at any point in time varies depending on market conditions, expectations of future price or market rate movements and composition of the Company's financial assets and liabilities held, non-trading physical assets and contract portfolios. International projects can expose the Company to risks beyond those typical for its activities in its home market, including economic, geopolitical, geotechnical, military, adoption of new or expansion of existing tariffs and/or taxes or other restrictions, sanctions risk, partner or third-party intermediary misconduct risks, and other risks beyond the Company's control, including the duration and severity of the impact of global economic downturns.

While U.S. tariffs on Canadian goods and energy do not directly affect the Company, potential Canadian retaliatory measures could increase the cost of heavy equipment parts and components. The Company would seek to mitigate these impacts through alternative sourcing or contractual cost pass-throughs, though recovery may be delayed due to contract mechanisms normally being triggered by increases in price indexes rather than direct price increases. Tariffs or related measures could also reduce customer spending or result in delayed or cancelled projects, which could have a material adverse effect on our future earnings and financial position.

To manage the exposure related to changes in market risk, the Company has used various risk management techniques. Such instruments may be used to establish a fixed price for a commodity, an interest-bearing obligation or a cash flow denominated in a foreign currency. The Company also mitigates these risks through specific contract provisions, insurance coverage and financial instruments where applicable.

The sensitivities provided below are hypothetical and should not be considered to be predictive of future performance or indicative of earnings on these contracts.

*i) Foreign exchange risk* 

The Company is exposed to foreign exchange risk due to a portion of its operations occurring in currencies other than the Canadian dollar (CAD), primarily the Australian dollar (AUD) and U.S. dollar (USD). Fluctuations in exchange rates may impact the Company's consolidated financial results, including the Consolidated Statements of Operations and Comprehensive Income and the translation of the Consolidated Balance Sheet.

The Company also incurs foreign exchange risk through transactions in non-CAD currencies, including purchases of equipment, spare parts, and certain general and administrative goods and services. These exposures are generally short-term, and past exchange rate fluctuations have not had a material impact. When considered significant, the Company may mitigate exposure by transacting in CAD, AUD, or USD. Additionally, the Company's Credit Facility allows borrowings in both CAD and AUD, providing flexibility to manage currency exposure related to these transactions.

*ii) Interest rate risk* 

The Company is exposed to interest rate risk from the possibility that changes in interest rates will affect future cash flows or the fair values of its financial instruments. Interest expense on borrowings with floating interest rates, including the Company's Credit Facility, varies as market interest rates change. At December 31, 2025, the Company held $174.2 million of floating rate debt pertaining to its Credit Facility (December 31, 2024 – $395.8 million). As at December 31, 2025, holding all other variables constant, a 100 basis point change to interest rates on the outstanding floating rate debt will result in $1.7 million corresponding change in annual interest expense.

The fair value of financial instruments with fixed interest rates fluctuate with changes in market interest rates. However, these fluctuations do not affect earnings, as the Company's debt is carried at amortized cost and the carrying value does not change as interest rates change.

The Company manages its interest rate risk exposure by using a mix of fixed and variable rate debt.

**f) Credit risk** 

Credit risk is the risk that financial loss to the Company may be incurred if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company manages the credit risk associated with its cash by holding its funds with what it believes to be reputable financial institutions. The Company is exposed to credit risk through its accounts receivable and contract assets as a significant portion of revenue is derived from a small group of customers. Credit risk for trade and other accounts receivables and contract assets are managed through established credit monitoring activities. The credit worthiness of new customers is subject to review by management through consideration of type of customer and the size of the contract. The Company has also mitigated risk through diversification of its operations through investments in joint ventures and acquisitions. Joint ventures are accounted for using the equity method and therefore the Company's share of revenues, accounts receivable and contract assets are not included in the tables below.

Where the Company generates revenue under its subcontracting arrangement with MNALP, the final end customer is represented in the tables below.

The following customers accounted for 10% or more of total revenues:

At December 31, 2025, there were approximately $6,943 of total unrecognized compensation costs related to non–vested share–based payment arrangements under the PSU plan (December 31, 2024 – $5,141) and these costs are expected to be recognized over the weighted-average remaining vesting term of the PSUs of 1.8 years (December 31, 2024 – 1.7 years). During the year ended December 31, 2025, 115,346 units vested, which were settled with common shares purchased through a trust arrangement at a factor of 0.95 common shares per PSU based on performance against grant date criteria (December 31, 2024 – 61,935 units at a factor of 0.55 vested and settled).

The Company estimated the fair value of the PSUs granted during the years ended December 31, 2025, and 2024 using a Monte Carlo simulation with the following assumptions:

---

| | | |
|:---|:---|:---|
|  | **2025** | 2024 |
| &nbsp;&nbsp; Risk-free interest rate | **2.62%** | 3.83% |
| &nbsp;&nbsp; Expected volatility | **37.10%** | 36.50% |

---

**c) Deferred stock unit plan** 

Prior to January 1, 2021, under the Company's shareholding guidelines non-officer directors of the Company were required to receive at least 50% and up to 100% of their annual fixed remuneration in the form of DSUs, at their election. The shareholding guidelines were amended effective January 1, 2021, to require directors to take at least 60% of their annual fixed remuneration in the form of DSUs if they do not meet shareholding guidelines, and to take between 0% and 100% of their annual fixed remuneration in the form of DSUs if they do meet shareholding guidelines. In addition to directors, eligible executives can elect to receive up to 50% of their annual short-term incentive plan compensation in the form of DSUs.

The DSUs vest immediately upon issuance and are only redeemable upon departure, retirement or death of the participant. DSU holders that are not US taxpayers may elect to defer the redemption date until a date no later than December 1 of the calendar year following the year in which the departure, retirement or death occurred.

Pursuant to the IMC Purchase Agreement, IMC shareholders will receive upfront cash consideration determined based on a formula leveraging IMC's equity book value, subject to certain post-closing adjustments, as well as deferred consideration in the form of a seller takeback financing payable, and contingent consideration.

The acquisition is valued at approximately $125 million in Canadian dollars. The estimated upfront payment of approximately $40 million will be funded by the Company's existing revolving credit facility. In addition, NACG plans to assume secured equipment financing of $45 million. The remaining $40 million of consideration will be settled through structured earn-out and deferred payment mechanisms payable to the vendors over the next four years.

The transaction is subject to customary closing conditions, including approval by the Australian Competition and Consumer Commission under section 51ABX of the Competition and Consumer Act 2010. The transaction is expected to close early in the second quarter of 2026. The estimate of the financial effect, including the fair value of consideration transferred and the allocation to the acquired assets and assumed liabilities, is pending on the closing date and a formal valuation process. The preliminary purchase price allocation will be determined following the closing date.

The acquisition of IMC is a strategic extension of the Company's client base into the Western Australia market, with a strong commodity market presence including base metals, precious metals and critical and rare earth minerals.

In 2025, the Company incurred $475 of acquisition-related costs for this acquisition. These expenses are included in general and administrative expenses on the Consolidated Statements of Operations and Comprehensive Income for the year ended December 31, 2025. To date, the Company has incurred an additional $322 of acquisition-related costs subsequent to December 31, 2025.
