In typical NACG fashion, I’m extremely happy to report that we accomplished that goal and exceeded all expectations. I’m a person that values simple tangible results over hype and flash. I believe this way of looking at things is part of the NACG culture and the way most of our employees and customers feel as well. We are a business that does what it says it is going to do. We value results over stories and are focused on continuous, long-term success. I hope you will find the ensuing paragraphs highlighting 2022 accomplishments and 2023 focus as confirmation of the value in maintaining and continuing to build on this practical and effective corporate culture. 2022 Operational Highlights • Steady improvements in equipment utilization since the middle of the year reaching 75% in the fourth quarter, the highest Q4 utilization rate in company history • Increased and, more importantly, retained critical maintenance headcount despite pervasive shortages throughout the mining and construction industries • Managed inflationary pressures through operational excellence, cost discipline, and transparent contract escalation amendment negotiations • Completed second life rebuilds and commissioned nine ultra-class & 240-ton haul trucks further improving our low-cost advantage over competitors • Commenced earthworks at the Fargo-Moorhead flood diversion project with initial cost/risk analyses showing the project tracking on budget and as scheduled • Acquired and integrated a key maintenance service supplier, ML Northern Services Ltd., with the objective of lowering operating costs and improving fleet support capabilities • Installed telematics packages on majority of heavy equipment assets to improve centralized machine health monitoring and provide additional data for operational efficiency improvements • Extended contract at the Kearl mine to 2027 through the continuously growing Indigenous partnership with the Mikisew Cree First Nation 4 NORTH AMERICAN CONTRUCTION GROUP 2022 Financial Highlights • Achieved combined annual revenue over $1.0 billion, an annual increase of over 30% • Set a new high fleet replacement cost of over $2.1 billion, further increasing barriers to entry • Realized adjusted EBITDA of $245M and EPS of $2.41 for the year, both new corporate records • Disciplined capital spending resulted in record free cash flow • Bought back 2.2 million shares representing 8% of common shares outstanding • Commenced a total return swap agreement for up to 1.0 million of common shares • Doubled the annual dividend rate to 32 cents per share • Reduced net debt by $13 million, a 4% reduction for the year 2023 Priorities and Focus From an operational perspective, safety remains a priority and a core value to us as we look to integrate new technology into our equipment and increase our support of front-line supervisors and new workers alike. We will likewise continue to focus on equipment utilization and all the correlated initiatives that support our heavy equipment fleet. Technology and telematics are becoming increasingly important elements in the objective to maintain consistent improvements while attracting, training, and retaining skilled maintenance labour will continue to be a priority for improving fleet utilization. We have also provided a clear line of sight in our bid pipeline and expected tender wins to increase our backlog to over $2 billion dollars before 2023 is over. We see this as confirmation of our safe, low-cost preferred contractor status. Capital allocation is a key focus for us and we expect our projected free cash flow range of $85 to $105 million to give us flexibility in that regard. We have already taken the step of increasing our dividend and deleveraging presents an attractive opportunity at current interest rate levels. Of course, we have an established history of engaging in share repurchases where we see value in that for our shareholders and are also always seeking growth opportunities, whether organically or through acquisition. Capital allocation is something we analyze on a continuing basis and we will always be opportunistic in directing our cash flow in a way that maximizes value. Thanks for your investment in NOA and I look forward to sharing the next set of results with you in late April as we progress through what we expect to be a smoother year. We believe 2023 will be another banner year for NACG as inflation fluctuations have eased and we benefit from high equipment demand and stronger-for- longer commodity markets. We will continue to execute our strategy demonstrating intrinsic value which we believe will be rewarding for our shareholders. Sincerely, Joseph C. Lambert President & Chief Executive Officer February 15, 2023 ANNUAL REPORT 2022 5 2023 Vision SAFETY SUSTAINABILITY EXECUTION DIVERSIFICATION 6 NORTH AMERICAN CONTRUCTION GROUP SAFETY Our Company is guided by our standard principle to promote the safe, environmentally responsible operations by ensuring that the hazards and environmental impacts associated with our day to day work activities are clearly understood and appropriately managed. In 2022, our Total Recordable Injury Rate (“TRIR”) was 0.53 on a target of 0.50. We will work continuously to improve our safety management system and improve our process including safe work practices for identified risks and hazards found in the work we do. NACG recognizes that to achieve our safety vision, we must make our learning systems smarter and more prepared for the potential failures we uncover. We must continually gather information to help prevent any adverse outcomes for our workers and the Company. We will take the time to help our workers understand the importance of learning from each other and in turn our leadership learning from our workers. Through gathering information about our systems and critical tasks it will help identify the places where incidents are most likely to happen and ultimately help us prevent future events. SAFETY PRINCIPLES  Health, safety and environment are recognized as an integral part of our business.  Our focus on people and relationships, and our uncompromising commitment to health and safety, allows us to acquire some of the best talent in the industry.  We are committed to elevating the standard of excellence in health, safety and environmental protection with continuous improvement along with greater accountability and compliance. Our aim is to have zero incidents.  NACG wants to be recognized as a progressive contractor and industry leader. We will continue to set new standards for safety excellence in the heavy construction and mining sector. ANNUAL REPORT 2022 7 SUSTAINABILITY Since our inception 70 years ago, NACG has touted an ingrained safe and low-cost provider culture. We believe this culture is key to our business success. We also believe that adopting a strong culture of sustainability, one that balances environmental, social and economic performance, is imperative to long-term success as an industry leader. We have the internal skill sets, individual and corporate desire, and functional ability to operate sustainably in each and every role within our company. Just as cost- consciousness and safe practices are not solely the responsibility of our finance and safety teams, sustainability is the responsibility of every employee. Over the coming years, we will look to further advance our sustainability goals by formally implementing systems and processes that align with our values and meet the needs of our customers, partners and key stakeholders. As part of this objective, we released our 2023 Sustainability Report at the same time as our 2022 financial results. This third annual report provides a structured framework for environmental, social, and governance initiatives moving forward. We plan to continue to issue future reports around this time each year which will allow stakeholders to measure progress in a variety of business areas with increasing rigor and metrics. The 2023 Sustainability Report is available on the Company’s website at www.nacg.ca/social-responsibility. 8 NORTH AMERICAN CONTRUCTION GROUP COMMITTED TARGETS 1 Diversity We recognize the importance of having a diverse organization, and that starts at the top. Therefore, we have committed to 30% gender diversity on both the Board of Directors and amongst our senior leadership group. 2 Emissions Reduction Our scope 1 emissions are derived from combustion of diesel from our off-road heavy equipment fleet. We’ve committed to reduce our scope 1 emissions intensity by 10% by 2025 and 20% by 2028. 3 Total Recordable Injury Rate Of 0.5 Or Less We believe all workplace incidents are preventable and will continue to strive for ongoing safety excellence through building on process and culture. A longstanding core goal of NACG, TRIR will continue to be used as one of our benchmarks to measure our safety performance. TRIR is an industry and nationally recognized standard safety metric and will keep the Company in line with our clients. ANNUAL REPORT 2022 9 EXECUTION Operational excellence is the key to achieving expected margins & shareholder returns. We fully intend to further enhance our reputation for operational excellence as improving site conditions result in the return of long-held operating routines. We will continue to build on our industry leading fleet maintenance strategy to maximize fleet availability and utilization by leveraging our reliability programs, management systems and expertise. We will leverage technological improvements and innovation to improve our operating efficiency, cost structure and component lives.

Revenue diversity: We intend to leverage strategic partnerships, our equipment and expertise, and our recent investment in Nuna to secure heavy or light civil construction contracts for major resource or infrastructure projects across North America. Our current active bid pipeline has over $4.4B worth of projects being engineered and estimated. Service expansion: We intend to increase diversity by marketing our industry leading expertise in heavy equipment maintenance services. We intend to continue developing partnerships with parts and component rebuild companies that complement our maintenance service strategy, and we intend to leverage our purpose designed and built state-of-the-art maintenance facility, which is capable of handling the largest of our customers’ equipment assets to grow this service offering over the coming years. What Organic Diversification means to us “Leveraging our existing capabilities and competitive advantages to win diversified work” What we have to achieve this goal • Well established Indigenous partnerships • Large capacity facilities in Acheson, Alberta ready to maintain & rebuild equipment • Mobile heavy equipment fleet ready for service • Ability to remanufacture equipment components on a low-cost zero-hour basis • World-class ERP system & proven processes available for deployment to remote regions Adjusted EBIT Targets Diversified Adjusted EBIT 1, 2 2020 Actual 2021 Actual 2022 Target 2022 Actual 35% 50% 50% 50% 1 See 2022 Annual Report for Non-GAAP Financial Measures 2 Adjusted EBIT profile targets exclude potential acquisitions Diversified EBIT ANNUAL REPORT 2022 11 BOARD OF Directors Martin Ferron Chair of the Board Director Since: June 7, 2012 Joe Lambert Director Since: January 1, 2021 Bryan Pinney Lead Director and Chair of Audit Committee Director Since: May 13, 2015 John Pollesel Chair of Operations Committee Director Since: November 23, 2017 Maryse Saint-Laurent Chair of Governance & Sustainability Committee Director Since: August 8, 2019 Thomas Stan Chair of Human Resources & Compensation Committee Director Since: July 14, 2016 Kristina Williams Director Since: August 8, 2019 12 NORTH AMERICAN CONTRUCTION GROUP SENIOR Management Joe Lambert President & Chief Executive Officer Jason Veenstra Executive Vice President & Chief Financial Officer Barry Palmer Chief Operating Officer Jordan Slator Vice President & General Counsel David Kallay Vice President, Health, Safety, Environment and Human Resources ANNUAL REPORT 2022 13 Management’s Discussion and Analysis February 15, 2023 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, 2022, 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”), are available on the Canadian Securities Administrators’ SEDAR System at www.sedar.com, the Securities and Exchange Commission’s website at www.sec.gov and our company website at www.nacg.ca. 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”, “capital work in progress”, “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”, “growth capital”, “growth spending”, “invested capital”, “net debt”, “senior debt”, “share of affiliate and joint venture capital additions”, “sustaining capital”, “total capital liquidity”, “total combined revenue”, and “total debt”. We also use supplementary financial measures such as “gross profit margin” and “total net working capital (excluding cash)” 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”. 14 NORTH AMERICAN CONSTRUCTION GROUP OVERALL PERFORMANCE (Expressed in thousands of Canadian Dollars, except per share amounts) Year ended December 31, Revenue Total combined revenue(i) Gross profit Gross profit margin(i) Combined gross profit(i) Combined gross profit margin(i)(ii) Operating income Adjusted EBITDA(i) Adjusted EBITDA margin(i)(iii) Net income Adjusted net earnings(i) Cash provided by operating activities Cash provided by operating activities prior to change in working capital(i) Free cash flow(i) Purchase of PPE Sustaining capital additions(i) Growth capital additions(i) Basic net income per share Adjusted EPS(i) 2022 2021 Change $ 769,539 $ 654,143 $ 115,396 1,054,265 101,548 13.2% 151,129 14.3% 71,157 245,352 23.3% 67,372 65,912 169,201 182,511 70,008 111,499 113,095 — 812,226 90,417 13.8% 124,058 15.3% 55,128 207,333 25.5% 51,408 58,243 165,180 164,509 67,232 112,563 102,183 6,795 $ $ 2.46 2.41 $ $ 1.81 2.06 $ $ 242,039 11,131 (0.6)% 27,071 (1.0)% 16,029 38,019 (2.2)% 15,964 7,669 4,021 18,002 2,776 (1,064) 10,912 (6,795) 0.65 0.35 (i)See “Non-GAAP Financial Measures”. (ii)Combined gross profit margin is calculated using combined gross profit over total combined revenue. (iii)Adjusted EBITDA margin is calculated using adjusted EBITDA over total combined revenue. Revenue of $769.5 million represents a $115.4 million (or 18%) increase for the full year of 2022 when compared to 2021 as equipment utilization steadily and consistently improved over that 24-month period. Of the year-over-year increase, the second half of 2022 generated $77.8 million (or 67%) of the positive variance as six-month equipment utilization of 69% exceeded the 58% utilization experienced in the second half of 2021. Equipment utilization in the fourth quarter specifically benefited from the Q3 2022 onboarding initiatives of maintenance personnel. Since October, maintenance headcount levels remained consistent, which resulted in the overall lowering of the maintenance department’s equipment repair backlog. Also contributing to second half increases were equipment and unit rate adjustments applied in late Q3 2022 to reflect the specific inflationary cost pressures experienced in the Fort McMurray region. The purchase of ML Northern’s fuel and lube equipment fleet, which occurred on October 1, 2022, was integrated into our operations and generated equipment operating hours consistent with the expectation for Q4 2022. Regarding the positive variances in the first half of 2022, results generated by DGI (Aust) Trading Pty Ltd. (“DGI”), acquired on July 1, 2021, and the sale of ultra-class and 240-ton haul trucks, rebuilt through our external maintenance program, were the primary drivers. Combined revenue of $1,054.3 million in 2022 represents a $242.0 million (or 30%) year-over-year increase. Our share of revenue generated in 2022 by joint ventures and affiliates was $596.0 million compared to $332.4 million in 2021 (an increase of 79%). The Nuna Group of Companies (“Nuna”) built on its record Q3 2022 performance driven by activity at the gold mine in Northern Ontario. In addition to Nuna, our share of revenue was bolstered by the various joint venture initiatives which are all proceeding with strong momentum: i) the continued growth in top-line revenue from rebuilt ultra-class haul trucks now being owned by the Mikisew North American Limited Partnership (“MNALP”) ii) the consistent progress being made in the component rebuild programs managed and performed by the Brake Supply North American joint venture, and lastly iii) the increasingly important impact of the joint ventures dedicated to the Fargo-Moorhead flood diversion project which formally broke ground in Q3 and continued its ramp up of activities through Q4. For the full year 2022, gross profit was $101.5 million, or 13.2% of revenue, up from $90.4 million and down from 13.8% of revenue in the previous year. Strong top-line revenue growth drove the increase in gross profit during the MANAGEMENT’S DISCUSSION AND ANALYSIS 15 year. Persistent inflationary pressures negatively impacted gross profit margin due to pervasive cost increases throughout both our on-site and facility maintenance programs. The Company coordinated rate increases with customers and suppliers during the year to mitigate the impact of these inflationary pressures. Labour shortages in the Fort McMurray region increased labour costs through the requirement for third-party contractors and the inefficiencies experienced from high turnover and vacancy rates. Partial offsets of these factors were the full year contributions from DGI, which yielded higher margins on component and parts sales, and margins from operations support contracts at coal mines in Texas and Wyoming. Included in the gross profit margin for the year was depreciation of $119.3 million, or 15.5% of revenue, which is an increase from our prior year expense of $108.0 million but, more importantly, a decrease from our prior year rate of 16.5% as more productive operating hours generated higher revenue. General and administrative expenses (excluding stock-based compensation) were $25.1 million, or 3.3% of revenue, compared to $23.8 million, or 3.6% of revenue in the previous year. The slight decrease as a percentage of revenue reflects higher year-over-year revenue while gross costs increased slightly as a result of these higher business activity levels and the acquisition of DGI in Q3 2021. Adjusted EBITDA of $245.4 million represents an 18% increase from the prior year result of $207.3 million and reflects strong demand for the heavy equipment fleet and the sustained momentum of scopes being completed within our joint ventures. The percentage increase is consistent with the increase in combined revenue when factoring for the wage subsidies received in 2021. Adjusted EBITDA margin of 23.3% (prior year 25.5%) illustrates solid operating performance across all our various diversified work sites. The margin was adversely impacted by increased maintenance activities and input costs, particularly at the Millennium mine, incurred to ensure our fleet was operating at the highest capacity possible given the labour shortages experienced in the first half of 2022. Offsetting these decreases were the strong operating performances of the Aurora and Fort Hills mines and, as mentioned above, the strong diversified margin profile from parts and component sales by DGI. Net interest expense was $24.5 million for the year including approximately $1.1 million of non-cash interest, compared to $19.0 million and $1.1 million, respectively, in the previous year. Our average cash cost of debt for the year was 5.6% as rate increases posted by the Bank of Canada directly impact our Credit Facility and have a delayed impact as well on the rates for secured equipment-backed financing. Adjusted EPS of $2.41 on adjusted net earnings of $65.9 million is 17.0% up from the prior year figure of $2.06 and is consistent with the relative increase of adjusted EBITDA as depreciation, tax and interest generally tracked consistently with the prior year. Weighted- average common shares outstanding for the full years of 2022 and 2021 were 27.4 million and 28.3 million, respectively, which reflect substantial share purchases completed during both years. Free cash flow of $70.0 million is the culmination of adjusted EBITDA of $245.4 million, mentioned above, less sustaining capital additions of $113.1 million and cash interest paid during the year of $24.1 million. Changes in routine working capital balances had a modest impact on cash generated in 2022 with the remaining two drivers for free cash flow generation being i) the timing impacts of capital work in process and capital inventory which required initial cash investment as we build our maintenance and component rebuild capabilities and ii) growth in our joint ventures which require initial cash discipline to manage growth capital spending and working capital balances. As quantitative evidence of this timing impact, our equity in joint ventures grew by $19.7 million during the year which will translate into cash distributions over time. 16 NORTH AMERICAN CONSTRUCTION GROUP FINANCIAL HIGHLIGHTS Five-year financial performance (dollars in thousands except ratios and per share amounts) Operating Data Revenue Gross profit Gross profit margin(i) Operating income Adjusted EBIT(i) Adjusted EBITDA(i) Adjusted EBITDA margin(ii) Comprehensive income Adjusted net earnings(i) Per share information Basic net income per share Diluted net income per share Adjusted EPS(i) Balance Sheet Data Total assets Current portion of finance lease obligations and long- term debt Non-current portion of finance lease obligations and long-term debt Total debt(i) Cash Net debt(i) Total shareholders’ equity Invested capital(i) Year ended December 31, 2022 2021 2020(iii) 2019(iii) 2018(iii) $ 769,539 101,548 $ 654,143 90,417 $ 498,468 92,218 $ 715,110 94,338 $ 405,384 69,081 13.2% 13.8% 18.5% 13.2% 17.0% 71,157 113,845 245,352 23.3% 67,676 65,912 55,128 92,661 207,333 25.5% 51,410 58,243 67,122 81,418 174,336 29.9% 49,208 48,746 57,131 70,962 174,379 23.4% 36,878 43,721 30,218 43,072 101,834 24.7% 15,286 24,875 $ $ $ $ 2.46 2.15 2.41 979,513 $ $ $ $ 1.81 1.64 2.06 869,278 $ $ $ $ 1.75 1.60 1.73 839,063 $ $ $ $ 1.45 1.23 1.72 793,152 $ $ $ $ 0.61 0.54 1.00 689,554 42,089 44,728 43,158 47,680 62,136 382,823 424,912 (69,144) 355,768 305,919 340,898 385,626 (16,601) 369,025 278,463 386,169 429,327 (43,447) 385,880 248,443 364,412 412,092 (5,208) 406,884 180,119 322,006 384,142 (19,450) 364,692 149,721 $ 661,687 $ 647,488 $ 634,323 $ 587,003 $ 514,413 Outstanding common shares, excluding treasury shares Cash dividend declared per share 26,420,821 0.32 28,458,115 0.16 29,166,630 0.16 25,777,445 0.12 25,004,205 0.08 (i)See “Non-GAAP Financial Measures”.

The majority of this quarter-over-quarter positive variance was generated by the equipment fleets in the Fort McMurray region. Revenue increases were driven by year-over-year increases in equipment hours and with utilization increasing 10% over the same period in 2021. Year-over year gross revenue growth also reflects the cost inflationary rate adjustments on equipment and unit rates in the last half of 2022. Lastly, revenue was bolstered by the acquisition of ML Northern Services Ltd. (“ML Northern”) in the quarter. For the year ended December 31, 2022, revenue was $769.5 million, up from $654.1 million for the year ended December 31, 2021. The increase of 18% reflects the fourth quarter increases mentioned above combined with the full year impact of equipment fleet at the Fort Hills mine which was re-mobilized in the second half of 2021. Additionally, revenue was positively impacted by the full year results of DGI acquired in the second half of 2021.

The improvement in gross profit in the current period was driven by increases in utilization and the correlated efficiencies that come from increased operating hours. For the three months ended December 31, 2022, cost of sales were $155.0 million, up from cost of sales of $128.9 million in the same period last year. For the year ended December 31, 2022, gross profit was $101.5 million, or 13.2% of revenue, up from $90.4 million but slightly down from 13.8% of revenue in the previous year. The gross profit margin was impacted by persistent inflationary cost pressures throughout 2022. Increases in equipment costs combined with the strong labour demand in the Fort McMurray region drove higher costs throughout 2022. Furthermore, costs in 2021 were offset by wage subsidies received. These impacts were mitigated by updated equipment and unit rates agreed to with customers in the second half of 2022. For the year ended December 31, 2022, cost of sales were $548.7 million, up from cost of sales of $455.7 million in the same period last year. For the three months ended December 31, 2022, depreciation was $35.9 million (15.4% of revenue) up from $29.1 million (or 16.0% of revenue) in the same period last year. Depreciation for the year ended December 31, 2022, was $119.3 million (15.5% of revenue) up from $108.0 million (16.5% of revenue) for the year ended December 31, 2021. The increases in gross depreciation are the result of higher operating equipment hours by the fleet due to increased site activity when compared to 2021. The depreciation percentages in 2022 were lower than the comparable periods in 2021 due to more effective and productive use of the fleet as well as increased non-equipment related revenue from DGI and external maintenance customers. Operating income For the three months ended December 31, 2022, operating income was $31.6 million, up from $17.5 million during the same period last year. G&A expense, excluding stock-based compensation expense, was $6.6 million, or 2.8% of revenue for the three months ended December 31, 2022, up from $3.7 million, or 2.0% of revenue in the same period last year. The increase in the current period expense compared to prior year was due to the acquisition of ML Northern in Q4 2022, generally higher business activity levels, and the prior year recognition of reimbursable bid costs received in excess of amounts capitalized. 20 NORTH AMERICAN CONSTRUCTION GROUP For the year ended December 31, 2022, operating income was $71.2 million, up from $55.1 million for the year ended December 31, 2021. G&A expense, excluding stock-based compensation expense, was $25.1 million for the year ended December 31, 2022, or 3.3% of revenue, up from the $23.8 million, and down from 3.6% of revenue, recorded in the year ended December 31, 2021. The year-over-year gross increase was due to the acquisition of DGI in Q3 2021, the acquisition of ML Northern in Q4 2022, and generally higher business activity levels. For the three months and year ended December 31, 2022, stock-based compensation was $4.9 million and $4.8 million, respectively. For the three months and year ended December 31, 2021, stock-based compensation was $1.6 million and $11.6 million, respectively. The year-over-year change is primarily due to the impact of the fluctuating share price on the carrying value of our liability classified award plans.

In the year ended December 31, 2022, total interest expense was $24.5 million, up from the $19.0 million in the year ended December 31, 2021. The increase in interest expense in both periods can be primarily attributed to the higher balance on the Credit Facility and increases in the variable rate during 2022 on the credit facility leading to increased interest expense incurred. Cash related interest expense for the three months ended December 31, 2022, calculated as interest expense excluding amortization of deferred financing costs of $0.3 million, was $7.5 million and represents an average cost of debt of 7.1% when factoring in the Credit Facility balances during the quarter (compared to $4.9 million and 4.7% respectively for the three months ended December 31, 2021). Cash related interest expense for the year ended December 31, 2022, excluding deferred financing cost of amortization of $1.1 million, was $23.5 million and represents an average cost of debt of 5.6% (compared to 4.3% for the year ended December 31, 2021).

Nuna Group of Companies achieved outstanding operational performance during the year driven by activity at the gold mine in Northern Ontario. In addition to Nuna, equity earnings was bolstered by the various joint venture initiatives which are all gaining momentum: i) the continued investments being made by the Mikisew North American Limited Partnership in ultra-class haul trucks, ii) the consistent progress being made in the component rebuild programs managed and performed by the Brake Supply North American joint venture, and lastly iii) the increasingly important impact of the Fargo-Moorhead flood diversion project which broke ground in Q3 and continued its ramp up through Q4. For the year ended December 31, 2022, we realized a gain of $0.8 million on a swap agreement (December 31, 2021 - realized a gain of $2.7 million). We recorded income tax expense of $6.9 million and $17.1 million, respectively, during the three months and year ended December 31, 2022, an increase from the $2.5 million and $9.3 million income tax expense recorded in the respective prior year periods. The income tax expense was higher than in the same periods last year due to higher earnings. The current year income tax expense for wholly owned entities approximates our combined effective corporate tax rate of 23%. 22 NORTH AMERICAN CONSTRUCTION GROUP A reconciliation of basic net income per share to adjusted EPS is as follows: (dollars in thousands) Net income Interest from convertible debentures (after tax) Diluted net income available to common shareholders Adjusted net earnings(i) Weighted-average number of common shares Weighted-average number of diluted shares Basic net income per share Diluted net income per share Adjusted EPS(i) (i)See “Non-GAAP Financial Measures”.

MANAGEMENT’S DISCUSSION AND ANALYSIS 23 Mine support revenue in the oil sands region is traditionally highest during December to March as ground conditions are most favorable for work requiring frozen ground access. Delays in the start of the winter freeze required to perform this type of work reduce revenues or have an adverse effect on project performance in the winter period. The oil sands mine support activity levels decline when frost leaves the ground and access to excavation and dumping areas, as well as associated roads, are rendered temporarily incapable of supporting the weight of heavy equipment. The end of this period, which can vary considerably from year-to-year, is referred to as “spring breakup” and has a direct impact on our mine support activity levels. The level of project work executed by Nuna in each fiscal quarter is highly contingent on the relative mix of varying projects scopes and the geographic area where the work is executed. In general, activity peaks in the third quarter when temperatures in the remote North allow for project work to occur. On the most remote of projects, the active construction season can be less than 14 weeks. Projects executed in more southern regions of Canada are not as heavily impacted. On other seasonal projects, the spring/summer project execution season can be longer, spanning from June to October or November. However, site access is limited at times due to road bans. Other major projects, mainly winter road construction and maintenance occur in Q4 and Q1. Overall, full-year results are not likely to be a direct multiple or combination of any one quarter or quarters. In addition to revenue variability, gross margins can be negatively impacted in less active periods because we are likely to incur higher maintenance and repair costs due to our equipment being available for servicing.

As at December 31, 2021, our total capital liquidity was $233.1 million. Borrowing availability under finance lease obligations considers the current and long-term portion of finance lease obligations and financing obligations, including specific finance lease obligations for the joint ventures that we guarantee. There are no restrictions within the terms of our Credit Facility relating to the use of operating leases.

As at December 31, 2022 and December 31, 2021, we did not have an allowance for credit losses related to our trade receivables as we believe that there is minimal risk in the collection of past due trade receivables. We continue to monitor the credit worthiness of our customers. Our current working capital is significantly affected by the timing of the completion of projects and the contractual terms of the project. In some cases, our customers are permitted to withhold payment of a percentage of the amount owing to us for a stipulated period of time (such percentage and time period is usually defined by the contract and in some cases provincial legislation). This amount acts as a form of security for our customers and is referred to as a “holdback”. Typically, we are only entitled to collect payment on holdbacks if substantial completion of the contract has been performed, there are no outstanding claims by subcontractors or others related to work performed by us, and we have met the period specified by the contract, usually 45 days after completion of the work. However, in some cases, we are able to negotiate the progressive release of holdbacks as the job reaches various stages of completion. As at December 31, 2022, holdbacks totaled $0.4 million, comparable to the $0.4 million balance as at December 31, 2021. 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 are for capital expenditures, to fulfill debt repayment and interest payment obligations, to fund operating and finance lease obligations, to finance working capital requirements, and to pay dividends. When prudent, we have also used cash to repurchase our common shares. We anticipate that we will have enough cash from operations to fund our annual expenses, planned capital spending program and meet current and future working capital, debt servicing and dividend payment requirements in 2023 from existing cash balances, cash provided by operating activities and borrowings under our Credit Facility.

MANAGEMENT’S DISCUSSION AND ANALYSIS 27 Financing activities Cash used by financing activities during the three months ended December 31, 2022, was $14.5 million, which included $5.3 million of long-term debt repayments, $7.0 million in finance lease obligation repayments and $2.1 million in dividends. Cash used by financing activities for the three months ended December 31, 2021, was $40.0 million, which included $18.7 million of proceeds of long-term debt offset by $50.3 million of long-term debt repayments, $7.3 million in finance lease obligation repayments and $1.1 million in dividends. For the year ended December 31, 2022, cash used by financing activities was $19.5 million, which included $83.4 million of proceeds of long-term debt offset by $31.2 million of long-term debt repayments, $27.4 million in finance lease obligation repayments, $2.0 million of treasury share purchases, $7.8 million in dividends and $34.1 million in purchases under the share purchase program. Cash used by financing activities during the year ended December 31, 2021, was $92.8 million, driven by proceeds of long-term debt of $135.0 million offset by $164.4 million of long-term debt repayments, $33.9 million repayments towards finance lease obligations, $5.5 million of treasury share purchases, $3.6 million in financing costs, $4.4 million in dividends and $16.5 million in purchases under the share purchase program. 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. (dollars in thousands) Cash provided by operating activities Cash used in investing activities Capital additions financed by leases Add back: Growth capital additions Acquisition of DGI (Aust) Trading Pty Ltd.

(ii)Acquisition of ML Northern Services Ltd. is the purchase price less debt assumed and cash acquired. For the determination of free cash flow, the figure includes deferred consideration of $5,002. Free cash flow for the year ended December 31, 2022, was $70.0 million driven by strong operating results and higher profitability offset by investments in capital work in progress and joint ventures. Key drivers of free cash flow were adjusted EBITDA of $245.4 million, less sustaining capital additions of $113.1 million and cash interest paid of $24.1 million. Sustaining maintenance expenditures remained consistent with the expectations of the 2021 capital maintenance plan reflecting the necessary maintenance and capital purchases required to perform our contractual scopes. Cash interest in the year increased $7.1 million during 2022 primarily on higher rates but also on higher debt levels as the Q4 pay down of $52.4 million of net debt occurred late in the quarter. Changes in routine working capital balances had a modest impact on cash generated in 2022 with the remaining two drivers for free cash flow generation being i) the timing impacts of capital work in process and capital inventory which required initial cash investment as we build our maintenance and component rebuild capabilities and ii) growth in our joint ventures which require initial cash discipline to manage growth capital spending and working capital balances. As quantitative evidence of this impact, our equity in joint ventures grew by $19.7 million during the year which will translate into cash distributions over time. Free cash flow for the year ended December 31, 2021, was $67.2 million. Key drivers of free cash flow were adjusted EBITDA of $207.3 million, less sustaining capital additions of $102.2 million, cash interest paid of $17.0 million and joint venture capital additions of $14.3 million. Contractual obligations and other commitments Our principal contractual obligations relate to our long-term debt; finance and operating leases; and supplier contracts.

Our total contractual obligations of $537.5 million as at December 31, 2022 have increased from $471.9 million as at December 31, 2021 primarily related to an increase of $95.3 million related to our Credit Facility, offset by a decrease of $16.3 million of financing obligations, $7.5 million of finance leases and $7.6 million in convertible debentures. 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 September 20, 2022, we entered into an Amended and Restated Credit Agreement (the “Credit Facility”) with a banking syndicate that allows borrowing under the revolving loan to $300.0 million (down from $325.0 million) with the ability to increase the maximum borrowings by $50.0 million, subject to certain conditions. The amended agreement extended the facility maturity from October 8, 2024 to October 8, 2025, with an option to extend on an annual basis, subject to certain conditions. The Credit Facility permits finance lease obligations to a limit of $175.0 million (up from $150.0 million) and certain other borrowings outstanding to a limit of $20.0 million. In the amended agreement, the permitted amount of $175.0 million was expanded to include guarantees provided by us to permitted joint ventures, provided that value of such obligations shall not exceed the permitted amount. The Credit Facility has two financial covenants that must be tested quarterly on a trailing four-quarter basis. (cid:129) The first covenant is the Senior Leverage Ratio which is Bank Senior Debt plus outstanding letters of credit compared to Bank EBITDA less NACG Acheson Ltd. rental revenue. O O O “Bank Senior Debt” is defined as the Company’s long-term debt, finance leases and outstanding letters of credit, excluding Convertible Debentures, deferred financing costs, mortgages related to NACG Acheson Ltd. and debt related to investment in affiliates and joint ventures. “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, and certain other non-cash items included in the calculation of net income. The Senior Leverage Ratio must be less than or equal to 3.0:1. In the event the Company enters into a material acquisition, the maximum allowable Senior Leverage Ratio would include a step up of 0.50x for four quarters following the acquisition. (cid:129) The second covenant is the Fixed Charge Coverage Ratio which is defined as Bank EBITDA less cash taxes compared to Fixed Charges. MANAGEMENT’S DISCUSSION AND ANALYSIS 29 O O “Fixed Charges” is defined as cash interest, scheduled payments on debt, unfunded cash distributions by the Company and unfunded capital expenditures. The Fixed Charge Coverage Ratio is to be maintained at a ratio greater than 1.15:1. (cid:129) The calculation of both financial covenants excludes rental revenue of the wholly-owned subsidiary that owns our shop and head office complex. As at December 31, 2022, we were in compliance with our financial covenants. The Senior Leverage Ratio was 1.45:1, in compliance with the maximum of 3.0:1. The Fixed Charge Coverage Ratio was 1.79:1, in compliance with the minimum of 1.15:1. Borrowing activity under our Credit Facility As at December 31, 2022, there was $180.0 million borrowed against our Credit Facility along with $32.0 million in issued letters of credit under our Credit Facility (December 31, 2021 – $110.0 million and $33.9 million, respectively) and the unused borrowing availability was $88.0 million (December 31, 2021 – $181.1 million). Guarantees On December 3, 2021, we entered into an agreement with a financial institution to provide guarantee for drawn amounts under revolving equipment lease credit facilities which have a combined capacity of $80.0 million for 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. 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, 2022, we have provided guarantees on this facility of $53.4 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. Subsequent to December 2022, there was a $30.0 million increase to the capacity of these facilities. We also act as guarantor for equipment leases of Nuna, an affiliate of the Company, to avail more favourable financing terms. As at December 31, 2022, Nuna had an outstanding balance of $0.3 million under this arrangement. At this time, there have been no instances or indication that payments will not be made by Nuna. Therefore, no liability has been recorded. 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 February 10, 2023, there were 27,827,282 total voting common shares outstanding, which included 1,412,502 common shares held by the trust and classified as treasury shares on our consolidated balance sheets (27,827,282 common shares, including 1,406,461 common shares classified as treasury shares at December 31, 2022). We had no non-voting common shares outstanding on any of the foregoing dates.

Interest on the 5.00% convertible debentures is payable semi- annually on March 31 and September 30 of each year. The 5.50% convertible debentures are not redeemable prior to June 30, 2024, except under certain exceptional circumstances. The 5.50% convertible debentures may be redeemed at the option of the Company, in whole or in part, at any time on or after June 30, 2024 at a redemption price equal to the principal amount provided that the market price of the common shares is at least 125% of the original conversion price; and on or after June 30, 2026 at a redemption price equal to the principal amount. In each case, we are required to pay accrued and unpaid interest on the debentures redeemed to the redemption date. Both the 5.00% convertible debentures and the 5.50% convertible debentures are redeemable under certain conditions after a change in control has occurred. If a change in control occurs, we are 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. Share purchase program During the year ended December 31, 2022, we completed a Normal-Course Issuer Bid (“NCIB”) which had commenced on April 9, 2021 with purchases and cancellations totaling 82,592 common shares, at an average price of $17.92. The transactions resulted in decreases to the common shares account of $0.7 million and the additional paid-in capital account of $0.8 million. The NCIB terminated on April 8, 2022. On a combined basis, a total of 119,592 shares were purchased and cancelled under this NCIB. On April 11, 2022, we commenced a NCIB under which a maximum number of 2,113,054 common shares were authorized to be purchased. As at December 31, 2022, we purchased and subsequently cancelled 2,113,054 shares under this NCIB, at an average price of $15.45 per share. This resulted in decreases to the common shares accounts of $16.8 million and the additional paid-in capital accounts of $15.8 million. Swap Agreement On October 5, 2022, we entered into a swap agreement on our common shares with a financial institution for investment purposes. As at December 31, 2022, we recognized an unrealized gain of $778 on this agreement based on the difference between the par value of the converted shares and the expected price of the Company’s shares at contract maturity. The agreement is for 200,678 shares at a par value of $14.38, and an additional 152,100 shares at a par value of $17.84. Fair value of the shares as at December 31, 2022 was $18.08. The fair value of this swap is recorded in other assets (note 10) 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. This swap agreement is expected to mature in October 2023. During the year ended December 31, 2021, we recorded a net gain of $2,737 on the swap agreement related to the 5.50% convertible debentures issued in 2017 and redeemed through issuance of 4,583,655 common shares in April 2020. The gain recorded in 2021 was comprised of a realized gain of $7,071, offset by an unrealized gain from the year ended December 31, 2020 of $4,334. This swap agreement was completed on September 30, 2021 and the derivative financial instrument recorded on the Consolidated Balance Sheet was extinguished at that time.

Accounts receivable Other assets Accounts payable and accrued liabilities December 31, 2022 December 31, 2021 $ 65,294 $ 2,444 13,773 31,050 2,162 286 We enter into transactions with a number of our joint ventures and affiliates that involve providing services primarily consisting of subcontractor services, management fees, and equipment rental revenue, and equipment and component sales. These transactions were conducted in the normal course of operations, which were established and agreed to as consideration by the related parties. The 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, 2022 and 2021, revenue earned from these services was $666.1 million and $356.6 million, respectively. OUTLOOK Our strategic focus areas in 2023 remain: (cid:129) Safety – focus on people and relationships and maintain an uncompromising commitment to health and safety while elevating the standard of excellence in the field. (cid:129) Sustainability – commitment to the continued development of sustainability targets and consistent measurement of progress to those targets. (cid:129) Execution – enhance our record of operational excellence with respect to fleet maintenance, availability and utilization through leverage of our reliability programs, technical improvements and management systems. (cid:129) Diversification – continue to pursue further diversification of customer, resource and geography through strategic partnerships, industry expertise and/or investment in Indigenous joint ventures. 32 NORTH AMERICAN CONSTRUCTION GROUP The following table provides projected key measures for 2023 and actual results of 2022.

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: (cid:129) (cid:129) (cid:129) (cid:129) 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 claims and change orders on revenue contracts; 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; 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. 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) the completeness and accuracy of the original bid; costs associated with added scope changes; extended overhead 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; MANAGEMENT’S DISCUSSION AND ANALYSIS 33 (cid:129) (cid:129) (cid:129) (cid:129) 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. 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, 2022 and notes that follow, which sections are expressly incorporated by reference into this MD&A. Change in significant accounting policy – Basis of presentation Prior to July 1, 2021, we elected to apply the provision available to entities operating within the construction industry to apply proportionate consolidation to unincorporated entities that would otherwise be accounted for using the equity method. During the three months ended September 30, 2021, we elected to change this policy to account for these unincorporated entities using the equity method, resulting in a change to the consolidation method for Dene North Site Services and Mikisew North American Limited Partnership. This change allows for consistency in the presentation of our investments in affiliates and joint ventures. We have accounted for the change retrospectively according to the requirements of US GAAP Accounting Standards Codification (“ASC”) 250 by restating the comparative periods. For full disclosure, refer to note 22 in our Financial Statements for the year ended December 31, 2021. During the third quarter of 2022, the Company updated the presentation of project and equipment costs within the Consolidated Statement of Operations and Comprehensive Income to be combined as cost of sales. There has been no change in the Company’s accounting policy or change in the composition of the amounts now recognized within cost of sales. The change in presentation had no effect on the reported results of operations. The comparative period has been updated to reflect this presentation change. Accounting pronouncements recently adopted The Company adopted the new standard for debt with conversion and other options effective January 1, 2022. In September 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options and Derivatives and Hedging – Contracts in Entity’s own Equity. This accounting standard update was issued to address issues identified as a result of the complexity associated with applying US GAAP for certain financial instruments with characteristics of liabilities and equity. The adoption of this new standard did not have a material impact to the consolidated financial statements. For a complete discussion of accounting pronouncements, see the “Accounting pronouncements recently adopted” section of our consolidated financial statements for the year ended December 31, 2022 and notes that follow, which sections are expressly incorporated by reference into this MD&A. Financial instruments For a complete discussion of our use of financial instruments, see note 15 of our consolidated financial statements for the year ended December 31, 2022. 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. 34 NORTH AMERICAN CONSTRUCTION GROUP “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. “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. “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. “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. “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. “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. “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. As adjusted EBIT, adjusted EBITDA, adjusted net earnings and adjusted EPS 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) reflect our cash expenditures or requirements for capital expenditures or capital commitments or proceeds from capital disposals; reflect changes in our cash requirements for our working capital needs; reflect the interest expense or the cash requirements necessary to service interest or principal payments on our debt; include tax payments or recoveries that represent a reduction or increase in cash available to us; or reflect any cash requirements for assets being depreciated and amortized that may have to be replaced in the future. “Total debt” is defined as the sum of the outstanding principal balance (current and long-term portions) of: (i) finance leases; (ii) borrowings under our credit facilities (excluding outstanding Letters of Credit); (iii) convertible unsecured subordinated debentures; (iv) mortgage; (v) promissory notes; and (vi) financing obligations. We believe total debt is a meaningful measure in understanding our complete debt obligations. “Net debt” is defined as total debt less cash and cash equivalents recorded on the balance sheets. Net debt is used by us in assessing our debt repayment requirements after using available cash. “Senior debt” is defined as total debt, excluding convertible debentures, deferred financing costs, mortgages related to NACG Acheson Ltd. and debt related to investment in affiliates and joint ventures. Senior debt is used primarily for our bank covenants contained in the Credit Facility agreement. “Invested capital” is defined as total shareholders’ equity plus net debt. “Total capital liquidity” is defined as total liquidity plus unused finance lease and other borrowing availability under our Credit Facility. MANAGEMENT’S DISCUSSION AND ANALYSIS 35 “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. “Free cash flow” is defined as cash from operations less cash used in investing activities including finance lease additions but excluding cash used for growth capital. We believe that free cash flow is a relevant measure of cash available to service our total debt repayment commitments, pay dividends, fund share purchases and fund both growth capital expenditures and potential strategic initiatives. “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 5 – 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. “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. “Combined backlog” is a measure of the total of backlog from wholly-owned entities plus equity method investment backlog. “Growth capital” is defined as new or used revenue-generating and customer facing assets which are not intended to replace an existing asset and have been commissioned and are available for use. These expenditures result in a meaningful increase to earnings and cash flow potential. “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. “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 additions” is defined as capital expenditures, net and lease additions. “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 “Capital inventory” is defined as rotatable parts included in property, plant and equipment held for use in the overhaul of property, plant and equipment. “Capital work in progress” is defined growth capital and sustaining capital prior to commissioning and not available for use. 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. “Combined gross profit margin” is defined as combined gross profit divided by total combined revenue. “Adjusted EBITDA Margin” is defined as adjusted EBITDA 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. Supplementary Financial Measures “Gross profit margin” represents gross profit as a percentage of revenue. “Total net working capital (excluding cash)” represents net working capital, less the cash balance. 36 NORTH AMERICAN CONSTRUCTION GROUP 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, 2022 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) 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 in ICFR exists if a deficiency, or a combination of deficiencies, is 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, 2022, 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, 2022, our internal control over financial reporting is effective. In accordance with the published guidance of the U.S. Securities and Exchange Commission (SEC), management’s assessment of and conclusion on the effectiveness of our internal control over financial reporting did not include the internal controls of ML Northern, which is included in our 2022 consolidated financial statements and represented approximately 3% of total assets, 1% of revenues and 2% net income, respectively for the year ended December 31, 2022. 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, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by COSO. KPMG LLP’s audit of internal control over financial reporting of the Company also excluded an evaluation of the internal controls over financial reporting of ML Northern. 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. MANAGEMENT’S DISCUSSION AND ANALYSIS 37 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) our belief that there is minimal risk in the collection of past due trade receivables; our anticipation that we will have enough cash from operations to fund our annual expenses, planned capital spending program and meet current and future working capital, debt servicing and dividend payment requirements in 2023 from existing cash balances, cash provided by operating activities and borrowings under our Credit Facility; calculations of future interest payments that depend on variable rates; statements regarding backlog, including our expectation that $498.6 million of our backlog will be performed over 2023; and all financial guidance provided in the “Outlook” section of this MD&A, including projections related to Adjusted EBITDA, Adjusted EPS, sustaining capital, free cash flow, deleveraging, shareholder activity, growth spending, Senior Debt and Net Debt. 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: (cid:129) (cid:129) (cid:129) (cid:129) oil prices remaining stable and not dropping significantly in 2023; oil sands production continuing to be resilient to drops in oil prices due to our customer’s desire to lower their operating cost per barrel; continuing demand for heavy construction and earth-moving services, including in diversified resources and geographies; 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; 38 NORTH AMERICAN CONSTRUCTION GROUP (cid:129) our ability to maintain our expenses at current levels in proportion to our revenue; (cid:129) work continuing to be required under our master services agreements with various customers and such master services agreements remaining intact; (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) our customers’ continued willingness and ability to meet their contractual obligations to us; our customers’ continued economic viability, including their ability to pay us in a timely fashion; our customers and potential customers continuing to outsource activities for which we are capable of providing services; our ability to maintain the right size and mix of equipment in our fleet and to secure specific types of rental equipment to support project development activity 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; our continued ability to access sufficient funds to meet our funding requirements; 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; our relationships with the unions representing certain of our employees continuing to be positive; and 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. (cid:129) 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 effects of the COVID-19 pandemic and the resulting measures taken by governments, customers and by the Corporation have increased the difficulty in obtaining skilled labour. 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 union status, 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. (cid:129) Cash flow, Liquidity and Debt. As of December 31, 2022 we had $424.9 million of total debt 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) limit our ability to obtain additional financing to fund our working capital, capital expenditures, debt service requirements, potential growth or other purposes; limit our ability to use operating cash flow in other areas of our business as such funds are instead used to service debt; limit our ability to post surety bonds required by some of our customers; place us at a competitive disadvantage compared to competitors with less debt; increase our vulnerability to, and reduce our flexibility in planning for, adverse changes in economic, industry and competitive conditions; and 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. MANAGEMENT’S DISCUSSION AND ANALYSIS 39 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. (cid:129) Unit-price Contracts. Approximately 32%, 41% and 47% of our revenue for the years ended December 31, 2022, 2021 and 2020, 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) site conditions differing from those assumed in the original bid; the availability and cost of skilled workers; the availability and proximity of materials; unfavorable weather conditions hindering productivity; equipment availability and timing differences resulting from project construction not starting on time; and the general coordination of work inherent in all large projects we undertake. 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. (cid:129) 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. (cid:129) 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 90% and 92% of our total combined revenue for the years ended December 31, 2022 and 2021, respectively. (cid:129) 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 40 NORTH AMERICAN CONSTRUCTION GROUP 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. (cid:129) Inflation. The costs of performing work for our customers has recently been subject to inflationary pressures that are unusually high from an historical perspective, 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. 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. (cid:129) 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. (cid:129) 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. (cid:129) Customer Outsourcing. 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 MANAGEMENT’S DISCUSSION AND ANALYSIS 41 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. (cid:129) 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. (cid:129) Labour Disputes. The majority of our hourly employees are subject to collective bargaining agreements to which we are a party or are otherwise subject. Any work stoppage resulting from a strike or lockout could have a material adverse effect on our business, financial condition and results of operations. In order to minimize this risk, NACG has 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. (cid:129) 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. (cid:129) Foreign Exchange. We regularly transact in foreign currencies when purchasing equipment and spare parts as well as certain general and administrative goods and services. As such, we are exposed to the risk of fluctuations in foreign exchange rates. These exposures are generally of a short-term nature and the impact of changes in exchange rates has not been significant in the past. We may fix our exposure in either the Canadian dollar or the US dollar for these short-term transactions. (cid:129) (cid:129) 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, according, adversely affect our profitability at a level that depends on our total outstanding debt. 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. See the section entitled “Internal Systems and Processes” in our MD&A for further details. (cid:129) Health and Safety. We are subject to, and comply with, all health and safety legislation applicable to our operations. We have a comprehensive health and safety program designed to ensure our business is conducted in a manner that protects both our workforce and the general public. There can be no guarantee that we will be able to maintain our high standards and level of health and safety performance. An inability to maintain excellent safety performance could adversely affect our business by customers reducing existing work in response and by hampering our ability to win future work. (cid:129) 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 42 NORTH AMERICAN CONSTRUCTION GROUP 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. (cid:129) 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 $nil relating to disputed claims or unapproved change orders. (cid:129) Heavy Equipment Demand. As our work mix changes over time, we adjust our fleet to match anticipated future requirements. This involves 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. (cid:129) Price Escalators. Our ability to maintain planned project margins on longer-term contracts with contracted price escalators is dependent on the contracted price escalators accurately reflecting increases in our costs. If the contracted price escalators do not reflect actual increases in our costs, we will experience reduced project margins over the remaining life of these longer-term contracts. In strong economic times, the cost of labour, equipment, materials and sub-contractors is driven by the market demand for these project inputs. The level of increased demand for project inputs may not have been foreseen at the inception of the longer-term contracts with fixed or indexed price escalators resulting in reduced margins over the remaining life of the longer-term contracts. (cid:129) 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. (cid:129) 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 MANAGEMENT’S DISCUSSION AND ANALYSIS 43 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. (cid:129) 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. (cid:129) 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, 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. 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 the 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. (cid:129) 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. (cid:129) Risk Factors Related to COVID-19. While markets and economies have somewhat stabilized as governments and industry have implemented measures to mitigate the impacts of the pandemic, the situation continues to evolve. Should the pandemic worsen, we could be subject to additional or continued adverse impacts, including, but not limited to restrictions or limitations on the ability of our employees, contractors, suppliers and customers to conduct business due to quarantines, closures or travel restrictions, including the potential for deferral or cessation of ongoing or planned projects. The ultimate duration and magnitude of the pandemic and its financial effect on us is not known at this time. We are continuously monitoring the situation, however, and working with our customers and suppliers to mitigate its effects.

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 concluded that the Company’s system of internal control over financial reporting was effective as of December 31, 2022. In accordance with the published guidance of the U.S. Securities and Exchange Commission (SEC), management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of ML Northern, which is included in the 2022 consolidated financial statements and represented approximately 3% of total assets, 1% of revenues and 2% net income, respectively for the year ended December 31, 2022. 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, 2022, has also issued a report stating its opinion that the Company has maintained effective internal control over financial reporting as of December 31, 2022, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the COSO. KPMG LLP’s audit of internal controls over financial reporting of the Company also excluded an evaluation of the internal controls over financial reporting of ML Northern.

In our opinion, North American Construction Group Ltd. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, 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, 2022 and 2021, the related consolidated statements of operations and comprehensive income, changes in shareholders’ equity, and cash flows for the years then ended, and the related notes (collectively, the “consolidated financial statements”), and our report dated February 15, 2023 expressed an unqualified opinion on those consolidated financial statements. The Company acquired ML Northern Services Ltd. (“ML Northern”) during 2022, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2022, ML Northern’s internal control over financial reporting representing approximately 3% of total assets, 1% of revenues, and 2% of net income, respectively, as of and for the year ended December 31, 2022. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of ML Northern. 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 Management’s Report on Internal Control over Financial Reporting in the accompanying Management’s Discussion and Analysis. 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. A company’s internal control over financial reporting KPMG LLP is a Canadian limited liability partnership and a member firm of the KPMG network of independent member firms affiliated with KPMG International Cooperative (“KPMG International”), a Swiss entity. KPMG Canada provides services to KPMG LLP 46 NORTH AMERICAN CONSTRUCTION GROUP 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.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for 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, 2022, 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 February 15, 2023 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. 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 Matter 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 critical audit matters 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.

KPMG Canada provides services to KPMG LLP 48 NORTH AMERICAN CONSTRUCTION GROUP Estimation of total costs to be incurred for unit-price long-term contract revenue As discussed in note 2(c) to the consolidated financial statements, the Company recognizes revenues under four principal types of contracts: lump-sum, unit-price, time-and-materials, and cost-plus. For the year ended December 31, 2022, total contract revenues recognized by the Company were $769.5 million, including $15.0 million recognized under unit-price contracts with defined scope that were in-progress at year-end. Under its unit-price contracts with defined scope, the Company recognizes revenue over time based on the ratio of actual costs incurred to date divided by 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 the accuracy of the estimates made at the period-end date, primarily consisting of labor hours, equipment usage, and material costs and quantities to be incurred over the remaining contract periods. 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 within the Company’s revenue recognition process. This included controls related to the review of the ETC for unit-price contracts with defined scope that were in-progress at year-end. For a selection of these contracts, we evaluated the reasonableness of the Company’s determination of 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 inspected 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 economic indices used for the determination of 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 changes in the availability and proximity of equipment and materials. We evaluated the Company’s ability to estimate these amounts by comparing actual project margins to previous estimates. We have served as the Company’s auditor since 1998.

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. During the third quarter of 2022, the Company updated the presentation of project and equipment costs within the Consolidated Statement of Operations and Comprehensive Income to be combined as cost of sales. There has been no change in the Company’s accounting policy or change in the composition of the amounts now recognized within cost of sales. The change in presentation had no effect on the reported results of operations. The comparative period has been updated to reflect this presentation change. 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) 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 claims 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 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 54 NORTH AMERICAN CONSTRUCTION GROUP 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: (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) (cid:129) the completeness and accuracy of the original bid; costs associated with added scope changes; extended overhead 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. 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 the Company’s profitability. 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 our equipment maintenance and rebuild activities, along with our mining component supplier business. 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. CONSOLIDATED FINANCIAL STATEMENTS 55 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 mostly likely amount, constrained to an amount that 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: (cid:129) 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; (cid:129) The length of time between the recognition of revenue and the expected resolution; (cid:129) The Company’s experience with similar circumstances and similar customers, specifically when such items have predictive value; (cid:129) The Company’s history of resolution and whether that resolution includes price concessions or changing payment terms; and (cid:129) 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 56 NORTH AMERICAN CONSTRUCTION GROUP 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 a 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 approved in scope and not price, the associated revenue is treated as variable consideration, subject to constraint. 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 cost of sales 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 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. CONSOLIDATED FINANCIAL STATEMENTS 57 Information about the Company’s exposure to credit risks and impairment losses for trade and other receivables is included in note 15(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 obligation 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 5(c)). Remaining performance obligations are recorded within contract assets and contract liabilities on the Consolidated Balance Sheets. i) Contract liabilities Contract liabilities consist of advance payments and billings in excess of costs incurred and estimated earnings on uncompleted 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 available for 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: Assets Heavy equipment Basis Rate Units of production 3,000 – 120,000 hours Major component parts in use Units of production 2,500 – 70,000 hours Other equipment Licensed motor vehicles Office and computer equipment Furnishings, fixtures and facilities Buildings Leasehold improvements Land Straight-line Straight-line Straight-line Straight-line Straight-line Straight-line 5 – 10 years 5 – 10 years 4 – 10 years 10 – 30 years 10 – 50 years Over shorter of estimated useful life and lease term No depreciation No depreciation 58 NORTH AMERICAN CONSTRUCTION GROUP 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 1st 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. 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: Assets Internal-use software Customer relationship Basis Straight-line Straight-line n) Impairment of long-lived assets Rate 4 years 4 years 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 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, 2022, there were no impairment indicators identified, as there had been no material declines in the operating environment or expected financial results. o) Assets held for sale Long-lived assets are classified as held for sale when certain criteria are met, which include: (cid:129) management, having the authority to approve the action, commits to a plan to sell the assets; (cid:129) (cid:129) 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; CONSOLIDATED FINANCIAL STATEMENTS 59 (cid:129) (cid:129) (cid:129) 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 and the majority of its subsidiaries 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 subsidiary, which has an 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 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. 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 60 NORTH AMERICAN CONSTRUCTION GROUP 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 19(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. 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 19(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 criterion includes 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. At the maturity date, the Human Resources and Compensation Committee will assess actual performance against the performance criteria and determine the number of PSUs that have been earned. The Company intends to settle all PSUs with common shares purchased on the open market through a trust arrangement. 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 19(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. 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. The Company had a Share Option Plan which is described in note 19(d). Effective November 17, 2021, this plan was terminated. The Company accounts for all stock-based compensation payments that are settled by the issuance of equity instruments at fair value. Compensation cost is measured using the Black-Scholes model at the grant date and is expensed on a straight-line basis over the award’s vesting period, with a corresponding increase to additional paid-in capital. Upon exercise of a stock option, share capital is recorded at the sum of proceeds received and the related amount of additional paid-in capital. CONSOLIDATED FINANCIAL STATEMENTS 61 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 16(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 finance lease obligations, 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 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. 62 NORTH AMERICAN CONSTRUCTION GROUP 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. If any of the following criteria are met, the Company classifies the lease as a sales-type lease: (cid:129) The lease transfers ownership of the underlying asset to the lessee by the end of the lease term; (cid:129) The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise; (cid:129) 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; (cid:129) 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. (cid:129) 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: (cid:129) 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. (cid:129) 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 rate method over the term to maturity. 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 CONSOLIDATED FINANCIAL STATEMENTS 63 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 after 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 revenue and cost of sales. 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) Government assistance The Company may receive compensation from government-funded assistance, which provides compensation for expenses incurred. These amounts are recognized in the Consolidated Statements of Operations and Comprehensive Income on a systematic basis in the periods in which the expenses are recognized. These amounts are presented as a reduction to the related expense. In response to the economic slowdown caused by COVID-19, the Government of Canada introduced the Canada Emergency Wage Subsidy, an employer assistance program which ended in October 2021. For the year ended December 31, 2021, the Company recognized $13,244 of salary and wage subsidies presented as reduction of cost of sales and general and administrative expenses of $12,489 and $755, respectively. No amounts were received in 2022. y) 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. The Company does not hold or issue derivative financial instruments for trading or speculative 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. 64 NORTH AMERICAN CONSTRUCTION GROUP z) 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. The current portion of the consideration payable is recorded in accrued liabilities and long-term portion is recorded in other long-term obligations on the Consolidated Balance Sheets, with any subsequent changes to fair value recorded in other income in Consolidated Statement of Operations and Comprehensive Income. Acquisition-related costs are expensed when incurred in general and administrative charges. 3. Accounting pronouncements recently adopted a) Debt with conversion and other options The Company adopted the new standard for debt with conversion and other options effective January 1, 2022. In September 2020, the FASB issued ASU 2020-06, Debt – Debt with Conversion and Other Options and Derivatives and Hedging – Contracts in Entity’s own Equity. This accounting standard update was issued to address issues identified as a result of the complexity associated with applying US GAAP for certain financial instruments with characteristics of liabilities and equity. The adoption of this new standard did not have a material impact to the consolidated financial statements. 4.

During the year-ended December 31, 2022, the Company derecognized $3,706 in revenue recognized in the year- ended December 31, 2021, and $3,706 in contract assets recognized as at December 31, 2021, due to a customer directed change of scope in a project. This resulted in the work ultimately being completed under the as-invoiced method of revenue recognition rather than the cost-to-cost percentage method. During the year-ended December 31, 2022, the Company recognized revenue of $177,620 related to this project. c) Transaction price allocated to the remaining performance obligations The estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period is $52,526, all of which is expected to be recognized in 2023.

The amended agreement matures on October 8, 2025, with an option to extend on an annual basis, subject to certain conditions. The Credit Facility permits finance lease obligations to a limit of $175.0 million and certain other borrowings outstanding to a limit of $20.0 million. In the amended agreement, the permitted amount of $175.0 million was expanded to include guarantees provided by the Company to certain joint ventures. As at December 31, 2022, there was $32.0 million (December 31, 2021 – $33.9 million) in issued letters of credit under the Credit Facility and the unused borrowing availability was $88.0 million (December 31, 2021 – $181.1 million). As at December 31, 2022, there was an additional $46.6 million in borrowing availability under finance lease obligations (December 31, 2021 – $28.6 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 two financial covenants that must be tested quarterly on a trailing four-quarter basis. As at December 31, 2022, the Company was in compliance with its financial covenants. (cid:129) The first covenant is the Senior Leverage Ratio which is Bank Senior Debt plus outstanding letters of credit compared to Bank EBITDA less NACG Acheson Ltd. rental revenue. O “Bank Senior Debt” is defined as the Company’s long-term debt, finance leases and outstanding letters of credit, excluding Convertible Debentures, deferred financing costs, mortgages related to NACG Acheson Ltd. and debt related to investment in affiliates and joint ventures. O “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, and certain other non-cash items included in the calculation of net income. O The Senior Leverage Ratio must be less than or equal to 3.0:1. In the event the Company enters into a material acquisition, the maximum allowable Senior Leverage Ratio would include a step up of 0.50x for four quarters following the acquisition. (cid:129) The second covenant is the Fixed Charge Coverage Ratio which is defined as Bank EBITDA less cash taxes compared to Fixed Charges. O “Fixed Charges” is defined as cash interest, scheduled payments on debt, unfunded cash distributions by the Company and unfunded capital expenditures. O The Fixed Charge Coverage Ratio is to be maintained at a ratio greater than 1.15:1. The Credit Facility bears interest at Canadian prime rate, U.S. Dollar Base Rate, 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. The Company is also subject to non-refundable standby fees, 0.40% to 0.75% depending on the Company’s Total Debt to Bank EBITDA Ratio. Total debt (“Total Debt”) is defined in the Credit Facility as long-term debt including finance leases and letters of credit, excluding convertible debentures, deferred financing costs, the mortgage related to NACG Acheson Ltd., and other non-recourse debt. The Credit Facility is secured by a first priority lien on all of the Company’s existing and after-acquired property excluding the Company’s first securities interests on the Business Development Bank of Canada (“BDC”) mortgage. The Company acts as a guarantor for drawn amounts under revolving equipment lease credit facilities which have a combined capacity of $80.0 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, 2022, the Company has provided guarantees on this facility of $53.4 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 related to this guarantee. Subsequent to December 2022, there was a $30.0 million increase to the capacity of these facilities. CONSOLIDATED FINANCIAL STATEMENTS 73 The Company also acts as guarantor for equipment leases of Nuna Logistics Ltd. (“NLL”), an affiliate of the Company, to avail more favourable financing terms. As at December 31, 2022, Nuna had an outstanding balance of $0.3 million under this arrangement. At this time, there have been no instances or indication that payments will not be made by NLL. Therefore, no liability has been recorded related to this guarantee. b) Convertible debentures 5.50% convertible debentures 5.00% convertible debentures December 31, 2022 December 31, 2021 $ $ 74,750 $ 55,000 74,750 55,000 129,750 $ 129,750 The terms of the convertible debentures are summarized as follows: Date of issuance Maturity Conversion price Share equivalence per $1000 debenture Debt issuance costs 5.50% convertible debentures 5.00% convertible debentures June 1, 2021 June 30, 2028 $ March 20, 2019 March 31, 2026 $ 24.75 $ 26.25 $ 40.4040 $ 38.0952 $ 3,531 2,691 Interest on the 5.50% convertible debentures is payable semi-annually in arrears on June 30 and December 31 of each year, commencing on December 31, 2021. Interest on the 5.00% convertible debentures is payable semi- annually on March 31 and September 30 of each year. The 5.50% convertible debentures are not redeemable prior to June 30, 2024, except under certain exceptional circumstances. The 5.50% convertible debentures may be redeemed at the option of the Company, in whole or in part, at any time on or after June 30, 2024, at a redemption price equal to the principal amount provided that the market price of the common shares is at least 125% of the original conversion price; and on or after June 30, 2026, at a redemption price equal to the principal amount. In each case, the Company will pay accrued and unpaid interest on the debentures redeemed to the redemption date. Both the 5.00% convertible debentures and the 5.50% convertible debentures are redeemable under certain conditions after a change in control has occurred. If a change in control occurs, we are 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. c) Financing obligations During the year ended December 31, 2021, the Company recorded new financing obligations of $11,700. The financing contract expires on February 9, 2026. The Company is required to make monthly payments over the life of the contract with an annual interest rate of 2.23%. The financing obligations are secured by the corresponding property, plant and equipment. d) Mortgage On October 28, 2021, the Company entered into an updated mortgage agreement with BDC which increased the mortgage amount from $21.1 million to $30.0 million. The updated mortgage includes an additional loan of $7.0 million for a building expansion and a $1.9 million cash advance. The mortgage has a maturity date of November 1, 2046, and bears interest at 3.40%. The mortgage is secured by the corresponding land and building in Acheson, Alberta. e) Promissory notes During the year ended December 31, 2022, the Company recorded a new equipment promissory note of $3.4 million. The contract expires on May 13, 2026. The Company is required to make monthly payments over the life of the contract with an annual interest rate of 5.85%. The promissory note is secured by the corresponding property, plant and equipment. During the year ended December 31, 2022, the Company made payments of $5.4 million towards promissory notes. 74 NORTH AMERICAN CONSTRUCTION GROUP During the year ended December 31, 2021, the Company recorded a new equipment promissory note of $4.3 million. The contract expires on August 5, 2025. The Company is required to make monthly payments over the life of the contract with an annual interest rate of 4.20%. The promissory note is secured by the corresponding property, plant and equipment. The Company also acquired a new promissory note of $0.4 million upon acquisition of DGI (note 20). The contract expires in November 2023 and bears interest at 2.90%.

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 and such value may never actually be realized. The fair values of the Company’s cash, accounts receivable, loans to affiliates and joint ventures (included in other assets), 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: Convertible debentures Financing obligations Mortgage b) Swap agreement December 31, 2022 December 31, 2021 Fair Value Hierarchy Level Level 1 Level 2 Level 2 Carrying Amount 129,750 32,889 29,231 Fair Value 131,795 30,783 24,329 Carrying Amount 129,750 47,945 30,000 Fair Value 135,963 47,010 29,756 On October 5, 2022, the Company entered into a swap agreement on its common shares with a financial institution for investment purposes. As at December 31, 2022, the Company recognized an unrealized gain of $778 on this agreement based on the difference between the par value of the converted shares and the expected price of the Company’s shares at contract maturity. The agreement is for 200,678 shares at a par value of $14.38, and an additional 152,100 shares at a par value of $17.84. The fair value of the shares as at December 31, 2022, was $18.08. The fair value of this swap is recorded in other assets (note 10) 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. This swap agreement is expected to mature in October 2023. CONSOLIDATED FINANCIAL STATEMENTS 75 During the year ended December 31, 2021, the Company recorded a net gain of $2,737 on the swap agreement related to the 5.50% convertible debentures issued in 2017 and redeemed through issuance of 4,583,655 common shares in April 2020. The gain recorded in 2021 was comprised of a realized gain of $7,071, offset by an unrealized gain from the year ended December 31, 2020, of $4,334. This swap agreement was completed on September 30, 2021, and the derivative financial instrument recorded on the Consolidated Balance Sheet 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 Company is also exposed to concentration risk through its revenues which is mitigated by the customers being large investment grade organizations. 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 further mitigated this risk through diversification of its operations. This diversification has primarily come through investments in joint ventures which are accounted for using the equity method. Revenues from these investments are not included in consolidated revenue. 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 $88.0 million on the Credit Facility (December 31, 2021 – $181.1 million) and an additional $46.6 million in borrowing availability under finance lease obligations (December 31, 2021 – $28.6 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. 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 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 regularly transacts in foreign currencies when purchasing equipment and spare parts as well as certain general and administrative goods and services. These exposures are generally of a short-term nature and the impact of changes in exchange rates has not been significant in the past. The Company may fix its exposure in either the Canadian Dollar or the US Dollar for these short-term transactions, if material. 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, 2022, the 76 NORTH AMERICAN CONSTRUCTION GROUP Company held $180.0 million of floating rate debt pertaining to its Credit Facility (December 31, 2021 – $110.0 million). As at December 31, 2022, holding all other variables constant, a 100 basis point change to interest rates on the outstanding floating rate debt will result in $1.8 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 also exposed to credit risk through its accounts receivable and contract assets. Credit risk for trade and other accounts receivables and contract assets are managed through established credit monitoring activities. The following customers accounted for 10% or more of total revenues: Year ended December 31, Customer A Customer B Customer C Customer D 2022 31% 24% 21% 14% 2021 38% 27% 10% 17% The concentration risk is mitigated primarily by the customers being large investment grade organizations. 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. Where the Company generates revenue under its subcontracting arrangement with MNALP, the final end customer is represented in the table above and in the table below. The following customers represented 10% or more of accounts receivable and contract assets: Customer 1 Customer 2 Customer 3 Customer 4 December 31, 2022 December 31, 2021 32% 16% 15% 11% 45% 6% 15% 15% The Company’s exposure to credit risk for accounts receivable and contract assets is as follows: Trade accounts receivable Holdbacks Accrued trade receivables Contract receivables, included in accounts receivable Other receivables Total accounts receivable Contract assets Total December 31, 2022 December 31, 2021 $ $ $ $ 39,625 $ 372 33,207 73,204 $ 10,607 83,811 $ 15,802 99,613 $ 51,774 380 12,266 64,420 4,367 68,787 9,759 78,546 CONSOLIDATED FINANCIAL STATEMENTS 77 Payment terms are per the negotiated customer contracts and generally range between net 15 days and net 60 days.
