Letter to Shareholders In my Q1 report, I used the analogy suggesting our business was warming up and ready to get back to delivering results consistent with pre-pandemic levels. I am pleased to say that the business and our NACG employees delivered into that expectation and with i) safety back in line with our high expectations, i ) a major infrastructure win, i i) an acquisition of a strategic Australian component supplier in DGI Trading Limited ("DGI"), iv) continued support of our long-standing oil sands clients, v) continued growth of our Indigenous partnerships, and vi) the launch of a project in hydrogen fuels; we are hitting our stride and ready to run for Olympic gold. Although not the most glamorous of events, we plan to win our gold in the marathon by giving our shareholders long distance, quality performance.
The quarter was not without its headwinds as the third wave of the pandemic had an amplitude far exceeding our expectations. The third wave impact in Fort McMurray had a 70% increase in positive cases and quarantined close contacts than any previous quarter. Thankful y, our pandemic plan minimized the spread of the virus in our workplace and employee recoveries were better than average. We currently have one employee with longer term effects who we hope to have back to health and back in the workforce here in Q3. The increased vaccination rates have had a dramatic positive impact and we are hopeful this is our last report on pandemic impacts to our business.
Our Q2 financial performance was as planned with impacts for major infrastructure wins, the DGI acquisition, and increased backlog not providing EBITDA benefit until later in the year with ful year benefits to be seen in 2022.
Some additional highlights of the quarter were:
•	Bid pipeline remains robust with recent adds in infrastructure, oil sands and other resource industries;
•	Project at gold mine in Northern Ontario now considered ramped up to peak summer production;
•	External maintenance program is back to the pre-pandemic run-rate;
•	Expansion of Acheson maintenance facility is on budget and scheduled for early Q4 completion;
•	Telematics project infrastructure and support expanded for major Q3 ramp up; and
•	Commenced feasibility study for dual fuel hydrogen combustion engine for reduced emissions.
As mentioned, our achievements over the past few months wil primarily impact 2022 and therefore our outlook for the remainder of 2021 remains largely consistent with what was disclosed in April. We have tightened the ranges while stil al owing for inherent risks of schedule changes and weather.
In closing, I would be remiss if I ignored our recent share price volatility. While market reception to our major infrastructure win was positive, and deservedly so, the drift down has been frustrating and, I believe, defies the diversification progress and performance we have achieved. As of the writing of this letter, our share price reflects roughly an 8x multiple on consensus earnings for 2022. With our performance and progress on growth and diversification, one could’ve reasonably thought that might be our EBITDA multiple. We believe our continued positive progress on our strategy wil create shareholder value and, like the marathon runner, we wil pace ourselves for the long haul maintaining capital al ocation flexibility in assessing share purchases and dividend yields while stil providing the capacity for meaningful debt reduction.
I look forward to sharing our Q3 results and our outlook for 2022 with you in October.

Management’s Discussion and AnalysisFor the three and six months ended June 30, 2021
July 28, 2021
The fol owing Management’s Discussion and Analysis ("MD&A") is as of July 28, 2021 and should be read in conjunction with the attached unaudited interim consolidated financial statements and notes that fol ow for the three and six months ended June 30, 2021, the audited consolidated financial statements and notes that fol ow for the year ended December 31, 2020 and our annual MD&A for the year ended December 31, 2020.
Al financial statements have been prepared in accordance with United States ("US") general y accepted accounting principles ("GAAP"). Except where otherwise specifical y indicated, al dol ar amounts are expressed in Canadian dol ars. The consolidated financial statements and additional information relating to our business, including our most recent Annual Information Form, are available through the Canadian Securities Administrators (www.sedar.com) and Securities and Exchange Commission (www.sec.gov) and our Company website at www.nacg.ca.
A non-GAAP financial measure is general y defined by securities regulatory authorities as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be adjusted in the most comparable GAAP measures. Non-GAAP financial measures do not have standardized meanings under GAAP and therefore may not be comparable to similar measures presented by other issuers. In our MD&A, we use non-GAAP financial measures such as "adjusted EPS", "adjusted net earnings", "adjusted EBIT", "adjusted EBITDA", "backlog", "capital additions", "capital expenditures, net", "capital inventory", "capital work in progress", "cash provided by operating activities prior to change in working capital", "equity investment depreciation and amortization", "equity investment EBIT", "free cash flow", "gross profit", "growth capital", "invested capital", "margin", "net debt", "senior debt", "sustaining capital" and "total debt".

As with many of our peers in North America, the latter part of Q2 2021 marked a noticeable and positive change with regards to the COVID-19 pandemic. However, specific to the Fort McMurray region, the early part of Q2 witnessed the third wave with their highest case counts being recorded during that time which had a correlated impact on our top line as some of our workforce was unavailable in April and particularly in May. The risk mitigation and safety measures in place significantly mitigated the impact. Operating hours on our NACG heavy equipment fleet were down 15% from Q1 2021 which was slightly more than expected largely driven by these workforce absences in April and May. Conditions quickly improved in June to the point where the month posted similar results to that of June 2019 thus providing tangible evidence of reaching pre-pandemic levels. This down and then up trend is reflected in revenue of $140.2 mil ion in Q2 2021 which was a 98% increase from the lows experienced in the extremely difficult Q2 2020. Other items of note in the quarter were: i) the external maintenance program returning to a quarterly run rate similar to 2019, i ) the resumption of work at the Fort Hil s mine and i i) a sizable increase in demand for mine site services provided by the Dene North Site Services joint venture.
While not consolidated in our revenue, the Nuna Group of Companies ("Nuna") achieved another very strong quarter as the gold mine project in Northern Ontario continues to ramp up. Our share of Nuna's revenue, which is consolidated in equity earnings, was $37.9 mil ion this quarter compared to $11.2 mil ion in Q2 2020. This step change in revenue correlates to the increase in operating hours on the equipment and was due to the work being completed by the joint venture owned by Nuna and North American. This revenue achievement highlights the benefit of diversification as combined revenue in Q2 remained relatively stable from Q1 whereas historical y the scope decrease from winter to spring was much more dramatic.
Throughout the pandemic, we have maintained our culture of cost discipline and have continued our halt on al discretionary and non-essential spending and this remained in place for the quarter. Direct general and administrative expenses (excluding stock-based compensation) were $6.0 mil ion in Q2 2021, equivalent to 4.3% of revenue, up from $3.6 mil ion but down from the equivalent 5.1% of revenue in Q2 2020.

SIGNIFICANT BUSINESS EVENTS
Increase in Committed Scope from Contract Amendment
On July 21, 2021, the Company announced a contract amendment to a multiple use agreement between the Mikisew North American Limited Partnership and a major oil sands producer. The agreement has an expiration date of December 2023 and the Company anticipates its share to be approximately $175 mil ion in additional revenue over the remainder of the agreement.
Infrastructure Project Award
On June 21, 2021, along with our partners Acciona and Shikun & Binui, we announced the award of Fargo-Moorhead flood diversion project in the United States. Our share of the project revenue wil be approximately $650 mil ion over the term of the contract. This award marks the largest infrastructure project in our history and underlines the significant earth works and construction expertise that we brought to the bid process.
Acquisition of Australian Component Supplier
On June 9, 2021, we announced that we had entered into a definitive agreement to acquire DGI Trading Pty Ltd., a supplier of production-critical mining components based in Kempsey, New South Wales, Australia, for an estimated purchase price of $23.5 mil ion. The transaction closed subsequent to the reporting period on July 1, 2021 with an initial payment of $10.3 mil ion funded through existing debt facilities. The purchase price is approximately equal to the net tangible assets of DGI, comprised primarily of inventory, plus subsequent payments over a four-year period based on the earnings of the business.
Issuance of $74.8 million of Convertible Debentures
On June 1, 2021, the Company closed an offering of 5.50% convertible unsecured subordinated debentures for aggregate gross proceeds of $65.0 mil ion. On June 4, 2021, underwriters exercised their over-al otment option, in ful , to purchase an additional $9.8 mil ion for aggregate gross proceeds of $74.8 mil ion. The debentures trade on the Toronto Stock Exchange ("TSX") under the symbol NOA.DB.B.
Normal Course Issuer Bid
On April 9, 2021, the Company commenced a normal course issuer bid ("NCIB") under which a maximum number of 2,000,000 common shares were authorized to be purchased. During the six months ended June 30, 2021, the Company purchased and subsequently cancel ed 37,000 shares under this NCIB, which resulted in a decrease of common shares of $0.3 mil ion and a decrease to additional paid-in capital of $0.2 mil ion. To comply with applicable securities laws, no more than 1,497,476 voting common shares wil be purchased on the New York Stock Exchange ("NYSE") or alternative trading systems. This NCIB wil be terminated no later than April 8, 2022.

Analysis of three and six months ended June 30, 2021 results
Revenue
For the three months ended June 30, 2021, revenue was $140.2 mil ion, up from $70.8 mil ion in the same period last year. The revenue growth in the current year is primarily attributable to the increased demand for our services as our customers continue to recover from the impacts of the COVID-19 pandemic. In the quarter, we continued to experience strong demand for equipment rental support and overburden removal activities at the Mil ennium mine and started performing tailings pond support activities in late Q2. Mine support work at the Kearl mine significantly ramped-up and the overburden and ditch construction work awarded in Q4 2020 positively impacted revenue. The suspension of work at the Fort Hil s mine caused a reduction in year-over-year revenue due to reduced demand for earthworks activity which is expected to return to a more normalized level of activity in Q3.
For the six months ended June 30, 2021, revenue was $308.6 mil ion, up from $269.6 mil ion in the same period last year. This increase of 14.5% reflects the Q2 factors mentioned above as wel as an expanded winter reclamation scope at the Aurora mine and higher volumes of civil construction services awarded at the Mildred Lake mine.
Management's Discussion and Analysis						M-5	North American Construction Group Ltd.
June 30, 2021

These increases were partial y offset by a reduction in winter reclamation work at the Mildred Lake mine and reduced activity at the Fort Hil s mine.
Gross profit
For the three months ended June 30, 2021, gross profit was $15.2 mil ion, and a 10.9% gross profit margin, down from a gross profit of $21.1 mil ion and gross profit margin of 29.8% in the same period last year. The lower gross profit and gross profit margin in the current period was driven by increased equipment maintenance activities as our fleet was more readily available for required repairs and maintenance during these months. Additional y contributing to the lower gross margin was manpower shortages from isolation requirements related to the third wave of COVID-19. Our operations support services for the coal mines in Texas and Wyoming positively impacted the margin in the quarter given the consistent nature of those contracts.
Q2 2021 results also include $6.2 mil ion of salary and wage subsidies of which $5.7 mil ion is included in gross profit. These subsidies from the Canada Emergency Wage Subsidy ("CEWS") program provided reimbursement for a portion of wages paid to employees in order to keep people employed during the pandemic and provided an offset for the significant costs incurred in the Fort McMurray region during the quarter. Q2 2020 results include $10.7 mil ion of salary and wage subsidies of which $9.3 mil ion is included in gross profit.
For the six months ended June 30, 2021, gross profit was $47.3 mil ion, and a 15.3% gross profit margin, down from $55.7 mil ion, and a 20.7% gross profit margin, in the same period last year. The decrease in gross profit was primarily driven by a reduction in site activity in Q1 2021 due to the COVID-19 pandemic, coupled with the suspension of work at Fort Hil s that began in March 2020. The gross profit margin was impacted by the Q2 factors discussed above and the reduction in activity on our winter works program at the Mildred Lake mine, as our heavy equipment fleet remained focused on overburden removal work in 2021. Increases in operating costs from employee absenteeism and disruptions to site operations due to the COVID-19 pandemic also contributed to the margin reduction. Partial y offsetting these decreases were the margins achieved on our operations support contracts for the coal mines in Texas, which started in Q2 2020 and Wyoming, which began in Q2 2019.
For the six months ended June 30, 2021, results include $12.0 mil ion of salary and wage subsidies of which $11.2 mil ion is included in gross profit. In the same period last year, results include $10.7 mil ion of salary and wage subsidies of which $9.3 mil ion is included in gross profit.
For the three months ended June 30, 2021, depreciation was $26.4 mil ion, or 18.9% of revenue, up from $11.6 mil ion, or 16.3% of revenue, in the same period last year. The increase in depreciation is the result of significantly increased equipment utilization when compared to the same period last year, which was significantly impacted by the COVID-19 pandemic. Depreciation as a percentage of revenue for three months ended June 30, 2021 is being impacted by our increasing ultra-class fleet which consists of haul trucks with load capacities greater than 320 tonnes. We have been strategical y investing in these haul trucks over the past two years via equipment rebuilds and major component overhauls. These investments result in increases to depreciable costs which consequently drive higher depreciation as a percentage of revenue.
For the six months ended June 30, 2021, depreciation was $57.6 mil ion, or 18.7% of revenue, up from $43.9 mil ion, or 16.3% of revenue, in the same period last year. The increase in depreciation for the six months ended June 30, 2021 is driven by the Q2 factors discussed above.
Operating income
For the three months ended June 30, 2021, we recorded operating income of $1.6 mil ion, a decrease of $13.0 mil ion from the $14.6 mil ion for the same period last year. General and administrative expense, excluding stock-based compensation expense, was $6.0 mil ion (or 4.3% of revenue) for the quarter, higher than the $3.6 mil ion (or 5.1% of revenue) in the prior year. Stock-based compensation expense increased by $5.4 mil ion compared to the prior year primarily due to the fluctuating share price on the carrying value of our liability classified award plans.
For the six months ended June 30, 2021, we recorded operating income of $24.5 mil ion, a decrease of $22.4 mil ion from the $46.9 mil ion for the same period last year. General and administrative expense, excluding stock-based compensation expense was $13.0 mil ion (or 4.2% of revenue) compared to the $12.7 mil ion (or 4.7% of revenue) for the six months ended June 30, 2020. Stock-based compensation expense increased by $14.7 mil ion compared to the prior year primarily due to the fluctuating share price on the carrying value of our liability classified award plans.

Income tax (benefit) expense							(540)			992	4,410		6,986
Total interest expense was $4.4 mil ion during the three months ended June 30, 2021, a slight increase from the $4.3 mil ion recorded in the prior year. During the six months ended June 30, 2021, total interest expense was $8.9 mil ion, a decrease from the $9.8 mil ion recorded in the prior year. The increase in the current period is due to the addition of new 5.50% convertible debentures issued on June 1, 2021. The decrease in the six months ended June 30, 2021 can be attributed to the lower outstanding balance on our Credit Facility.
Cash related interest expense for the three months ended June 30, 2021, calculated as interest expense excluding amortization of deferred financing costs of $0.2 mil ion, was $4.2 mil ion and represents an average cost of debt of 4.0% when factoring in the Credit Facility balances during the quarter (compared to 3.6% for the three months ended June 30, 2020). Cash related interest expense for the six months ended June 30, 2021 (excluding amortization of deferred financing cost of $0.4 mil ion and implied interest of $0.2 mil ion) was $8.3 mil ion and represents an average cost of debt of 3.9% (compared to 4.1% for the six months ended June 30, 2020).
Equity earnings in affiliates and joint ventures of $4.7 mil ion and $8.2 mil ion for the three and six months ended June 30, 2021, respectively, were generated by the NL Partnership and other various joint ventures consolidated using the equity method. The increase in the three and six months ended June 30, 2021 can be attributed to the ramp-up at the gold mine in Northern Ontario which commenced in late Q4 2020.
During the three and six months ended June 30, 2021, the Company recognized a realized gain of $0.9 mil ion and $7.1 mil ion, respectively, (unrealized gain at March 31, 2021 of $0.6 mil ion and at December 31, 2020 of $4.3 mil ion) on the swap agreement related to the 5.50% convertible debentures that were issued in 2017 and redeemed through issuance of 4,583,655 common shares in April 2020. This swap agreement was completed during the six months ended June 30, 2021.
We recorded deferred income tax benefit of $0.5 mil ion and expense of $4.4 mil ion for the three and six months ended June 30, 2021, respectively. Income tax benefit and expense relates to income excluding equity earnings in affiliates and joint ventures. The current period income tax amounts reflect lower levels of this income in the current year.
Net income and comprehensive income
For the three months ended June 30, 2021, we recorded $2.7 mil ion of net income and comprehensive income available to shareholders (basic net income per share of $0.10 and diluted net income per share of $0.09), compared to $13.3 mil ion net income and comprehensive income available to shareholders (basic net income per share of $0.46 and diluted net income per share of $0.42) recorded for the same period last year.
For the six months ended June 30, 2021, we recorded $22.1 mil ion net income and comprehensive income available to shareholders (basic net income per share of $0.78 and diluted net income per share of $0.72), compared to $32.3 mil ion net income and comprehensive income available to shareholders (basic net income per share of $1.19 and diluted net income per share of $1.07) for the same period last year.

Free cash flow of $6.1 mil ion in the quarter was negatively impacted by a variety of timing impacts related to working capital balances, capital work in process and cash balances owed by affiliates and joint ventures. Excluding these timing impacts, positive cash flow of $20.4 mil ion was generated by adjusted EBITDA of $42.4 mil ion detailed above offset by sustaining capital additions of $19.2 mil ion and cash interest paid of $2.8 mil ion. Sustaining maintenance expenditures remained consistent with the expectations of the front-loaded 2021 capital maintenance plan reflecting necessary sustaining maintenance required coming out of our busy winter season.
Free cash flow for the six months ended June 30, 2021 was $11.6 mil ion, the decrease was primarily driven by change in working capital balances which alone consumed $21.3 mil ion. Excluding timing impacts, positive cash flow of $34.5 mil ion was generated by the adjusted EBITDA of $103.5 mil ion, offset by sustaining capital additions of $61.7 mil ion, and cash interest paid of $7.3 mil ion.
Contractual obligations
Our principal contractual obligations relate to our long-term debt; finance and operating leases; capital for property, plant and equipment; and supplier contracts.

Credit Facility
On June 23, 2021, we entered into an amendment to our Credit Facility that al ows borrowing under the revolving loan to $325.0 mil ion, with the ability to increase the maximum borrowings by an additional $25.0 mil ion subject to certain conditions, and permits finance lease debt to a limit of $150.0 mil ion. This expanded facility matures on October 8, 2023, with an option to extend on an annual basis. The amended facility maintains financial covenant thresholds as wel as other debt limits.
As at June 30, 2021, the Credit Facility had borrowings of $130.0 mil ion (December 31, 2020 - $220.0 mil ion) and $0.9 mil ion in issued letters of credit (December 31, 2020 - $0.9 mil ion). At June 30, 2021, our borrowing availability under the Credit Facility was $194.1 mil ion (December 31, 2020 - $104.1 mil ion).
Under the terms of the Credit Facility the Senior Leverage Ratio is to be maintained at less than or equal to 3.0:1. In the event we enter into a material acquisition, the maximum al owable Senior Leverage Ratio would increase to 3.50:1 for four quarters fol owing the acquisition. The Fixed Charge Coverage Ratio is to be maintained at a ratio greater than 1.15:1.
Financial covenants are to be tested quarterly on a trailing four quarter basis. As at June 30, 2021, we were in compliance with the Company Credit Facility covenants. We ful y expect to maintain compliance with our financial covenants during the subsequent twelve-month period.

The 5.50% convertible debentures maybe 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 conversion price; and on or after June 30, 2026 at a redemption price equal to the principal amount. In each case, the Company wil pay accrued and unpaid interest on the debentures redeemed to the redemption date.

The 5.00% convertible debentures are only redeemable under certain conditions after a change in control has occurred. If a change in control occurs, we are required to offer to purchase al of the 5.00% convertible debentures at a price equal to 101% of the principal amount plus accrued and unpaid interest to the date of purchase.

During the three and six months ended June 30, 2021, we realized gains of $0.9 mil ion and $7.1 mil ion, respectively, (unrealized gain at March 31, 2021 of $0.6 mil ion and at December 31, 2020 of $4.3 mil ion) on the swap agreement related to 5.50% convertible debentures that were issued in 2017 and redeemed through issuance of 4,583,655 common shares in April 2020. This swap agreement was completed during the six months ended June 30, 2021.

Share purchase program

We completed the normal course issuer bid ("NCIB") commenced on March 12, 2020 under which a maximum number of 2,300,000 common shares were authorized to be purchased. During the three months ended March 31, 2021, we purchased and subsequently cancel ed 1,076,903 shares under this NCIB, which resulted in a decrease of common shares of $8.7 mil ion and an decrease to additional paid-in capital of $7.3 mil ion.

On April 9, 2021, we commenced a NCIB under which a maximum number of 2,000,000 common shares were authorized to be purchased. During the six months ended June 30, 2021, we purchased and subsequently cancel ed 37,000 shares under this NCIB, at an average price of $13.86 per share. This resulted in a decrease to common shares of $0.3 mil ion and a decrease to additional paid-in capital of $0.2 mil ion. This NCIB wil terminate no later than April 8, 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. For a ful discussion of our critical accounting estimates, see "Critical Accounting Estimates" in our annual MD&A for the year ended December 31, 2020.
Issued accounting pronouncements not yet adopted
Debt with conversion and other options
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 GAAP for certain financial instruments with characteristics of liabilities and equity. This ASU wil be effective January 1, 2022 with early adoption permitted. We are assessing the impact the adoption of this standard wil have on our consolidated financial statements.
Backlog
The fol owing summarizes our non-GAAP reconciliation of backlog as at June 30, 2021:
(dol ars in thousands)	Jun 30, 2021	Dec 31, 2020
Performance obligations per financial statements	$	234,019 $	126,816
Add: undefined committed volumes		391,385	614,285
Backlog	$	625,404 $	741,101
Revenue generated from backlog year to date	$	191,379 $	310,278
We recognized $191.4 mil ion of revenue from the backlog during the six months ended June 30, 2021, which decreased our backlog by $115.7 mil ion from December 2020 backlog of $741.1 mil ion. Differences from these metrics relate to addition of new contracts during the current year. As at June 30, 2021, we estimate that approximately $198.0 mil ion of our backlog reported above wil give rise to revenue generated over the remainder of 2021.
Our equity method investments also have a backlog of which our share was $869.2 mil ion as at June 30, 2021, (December 31, 2020 - $190.3 mil ion ), resulting in a combined backlog of $1,494.6 mil ion as at June 30, 2021 (December 31, 2020 - $931.4 mil ion ).
Non-GAAP financial measures
"Gross profit" is defined as revenue less: project costs; equipment costs; and depreciation. We believe that gross profit is a meaningful measure of our business as it portrays results before general and administrative costs, amortization of intangible assets and the gain or loss on disposal of property, plant and equipment. Management reviews gross profit to determine the profitability of operating activities, including equipment ownership charges and to determine whether property, plant and equipment are being al ocated effectively.
"Adjusted net earnings" is defined as net income and comprehensive income 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.
"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.
Management's Discussion and Analysis			M-15	North American Construction Group Ltd.
June 30, 2021

“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.
We believe that adjusted EBIT and adjusted EBITDA are meaningful measures of business performance because they exclude items that are not directly related to the operating performance of our business. Management reviews these measures to determine whether property, plant and equipment are being al ocated efficiently.
"Adjusted EPS" is defined as adjusted net earnings, divided by the weighted-average number of common shares.
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:
•	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.
"Margin" is defined as the financial number as a percent of total reported revenue. Examples where we use this reference and related calculation are in relation to "gross profit margin", "operating income margin", "net income margin", or "adjusted EBITDA margin". We wil often identify a relevant financial metric as a percentage of revenue and refer to this as a margin for that financial metric.
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.
"Total debt" is defined as the sum of the outstanding principal balance (current and long-term portions) of: (i) finance leases; (i ) borrowings under our Credit Facility (excluding outstanding Letters of Credit); (i i) 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 net of 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.
"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 al ocated 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.
“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 are made with the intent of resulting 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.
"Capital additions" is defined as capital expenditures, net and lease additions.
"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.
We believe that capital expenditures, net and its components are a meaningful measure to assess resource al ocation.
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 Executive Vice President & Chief Financial Officer to al ow 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 Executive Vice President & 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 the Executive Vice President & Chief Financial Officer concluded that as of June 30, 2021 such disclosure controls and procedures were effective.
Management’s report on internal control over financial reporting
In early 2020, many of our corporate office staff and site administrative staff began working remotely from home due to the COVID-19 pandemic. This change required certain processes and controls that were previously done or documented manual y to be completed and retained in electronic form. Despite the changes required by the current environment, there have been no significant changes to our internal controls over financial reporting (“ICFR”) for the three and six months ended June 30, 2021 that have material y affected, or are reasonably likely to affect, our ICFR.
LEGAL AND LABOUR MATTERS
Laws and Regulations and Environmental Matters
Please see “Our Business - Health, Safety and Environmental” in our most recent annual information form ("AIF") for a complete discussion on this topic.
Employees and Labour Relations
As at June 30, 2021, we had 191 salaried employees (June 30, 2020 - 166 salaried employees) and 1,563 hourly employees (June 30, 2020 - 892 hourly employees) in our western Canadian operations (excluding employees employed by Nuna). Of the hourly employees, approximately 84% of the employees are union members and work under col ective bargaining agreements (June 30, 2020 - 83% of the employees).
Management's Discussion and Analysis	M-17	North American Construction Group Ltd.
June 30, 2021

Existing terms of the col ective bargaining agreement with the International Union of Operating Engineers continue to apply while renewal discussions continue. We are optimistic that the renewal wil be finalized in Q3 2021. Our hourly workforce fluctuates according to the seasonality of our business and the staging and timing of projects by our customers. The hourly workforce for our ongoing operations ranges in size from approximately 700 employees to approximately 1,800 employees, depending on the time of year, types of work and duration of awarded projects.
We also utilize the services of subcontractors in our business. Subcontractors perform an estimated 7% to 10% of the work we undertake.
OUTLOOK
Our focus and priorities through the remainder of 2021 are as fol ows:
•	Safety - focus on people and relationships as we emerge from the pandemic, maintain an uncompromising commitment to health and safety while elevating the standard of excel ence in the field.
•	Sustainability - commitment to the continued development of sustainability targets and consistent measurement of progress to those targets.
•	Diversification - continue to pursue further diversification of customer, resource and geography through strategic partnerships, industry expertise and/or investment in Indigenous joint ventures.
•	Execution - enhance our record of operational excel ence with respect to fleet maintenance, availability and utilization through leverage of our reliability programs, technical improvements and management systems.
The fol owing table provides projected key measures for the remainder of 2021. These measures are predicated on contracts currently in place and the heavy equipment fleet that we own and operate.

On April 1, 2020, the Government of Canada announced the Canada Emergency Wage Subsidy program, which was created to help employers prevent further job losses by keeping employees on payrol during the COVID-19 pandemic. Recently, the Government of Canada extended this program to September 2021 and we expect that we wil be participating in this for al periods in which we are eligible.

that could affect us. See “Assumptions” above, “Assumptions” and “Business Risk Factors” in our annual MD&A for the year ended December 31, 2020 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, our most recent Annual Information Form.
Risk Management
We are exposed to liquidity, market and credit risks associated with its financial instruments. Management performs a risk assessment on a continual basis to help ensure that al significant risks related to our Company and operations have been reviewed and assessed to reflect changes in market conditions and operating activities.
Market Risk
Market risk is the risk that the fair value or future cash flows of a financial instrument wil fluctuate because of changes in market prices such as foreign currency exchange rates and interest rates. The level of market risk to which we are exposed at any point in time varies depending on market conditions, expectations of future price or market rate movements and composition of our financial assets and liabilities held, non-trading physical assets and contract portfolios. We have experienced no material change in market risk as of the quarter ended June 30, 2021. For a ful discussion of market risk please see our annual MD&A for the year ended December 31, 2020.
Risk Factors Related to COVID-19
In March 2020, the COVID-19 outbreak was declared a pandemic by the World Health Organization. Governments worldwide, including in Canada, enacted emergency measures to combat the spread of the virus, including the implementation of travel bans, quarantine periods and social distancing. The situation continues to evolve while markets and economies have somewhat stabilized, with governments and industry implementing measures to mitigate the impacts of the pandemic. As populations in Canada and many other countries are being vaccinated, governments are beginning to lift emergency measures. 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.

Notes to Interim Consolidated Financial Statements
For the three and six months ended June 30, 2021 (Expressed in thousands of Canadian Dol ars, except per share amounts or unless otherwise specified)(Unaudited)
1. Nature of operations
North American Construction Group Ltd. ("NACG" or the “Company”) was formed under the Canada Business Corporations Act. The Company and its predecessors have been operating continuously since 1953 primarily in western Canada but also in other parts of Canada and United States, providing a wide range of mining and heavy construction services to customers in the resource development and industrial construction sectors.
2. Significant accounting policies
Basis of presentation
These interim consolidated financial statements are prepared in accordance with United States general y accepted accounting principles ("US GAAP"). These interim consolidated financial statements include the accounts of the Company, its whol y-owned Canadian and United States incorporated subsidiaries and, via certain of its subsidiaries, the Company also holds investments in other Canadian corporations, partnerships and joint ventures. Al significant intercompany transactions and balances are eliminated upon consolidation.
The Company has prepared these interim consolidated financial statements on the same basis as its annual consolidated financial statements.
The Company's ful -year results are not likely to be a direct multiple of any particular quarter or combination of quarters due to seasonality. Oil sands mining revenues are typical y highest in the first quarter of each year as ground conditions are most favorable for this type of work while civil construction revenues are typical y highest during the third and fourth quarter, as weather conditions are most favorable for this type of work during these seasons. Mining activity declines near the end of the first quarter and through a large portion of the second quarter, as weather conditions make operations difficult. The duration of this period is referred to as “spring breakup”, as frost leaves the ground and many secondary roads are temporarily rendered incapable of supporting the weight of heavy equipment. In addition to revenue variability, gross profit margins can be negatively affected in less active periods because the Company is likely to incur higher maintenance and repair costs due to its equipment being available for servicing.
3. Recent accounting pronouncements not yet adopted
Debt with conversion and other options
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 GAAP for certain financial instruments with characteristics of liabilities and equity. This standard is effective January 1, 2022 with early adoption permitted. The Company is assessing the impact that the adoption of this standard may have on its consolidated financial statements.

8. 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. Al methods of fair value measurement result in a general approximation of fair value and such value may never actual y be realized.

The fair values of the Company’s cash, accounts receivable, contract assets, loans to affiliates and joint ventures, accounts payable, accrued liabilities and contract 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 and mortgages have carrying values that are not material y different than their fair values due to similar instruments bearing similar interest rates.

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

b) Risk management

The Company is exposed to liquidity, market and credit risks associated with its financial instruments. Management performs a risk assessment on a continual basis to help ensure that al significant risks have been reviewed and assessed to reflect changes in market conditions and operating activities.

In March 2020, the COVID-19 outbreak was declared a pandemic by the World Health Organization. Governments worldwide, including Canada, enacted emergency measures to combat the spread of the virus, including the implementation of travel bans, quarantine periods and social distancing. These factors created material disruptions to businesses global y, resulting in an economic slowdown.

The situation continues to evolve while markets and economies have somewhat stabilized, with governments and industry implementing measures to mitigate the impacts of the pandemic. As populations in Canada and many other countries are being vaccinated, governments are beginning to lift emergency measures. Should the pandemic worsen, the Company could be subject to additional or continued adverse impacts including, but not limited to, restrictions or limitations on the ability of 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 these impacts on the economy and the financial effect on the Company is not known. Estimates and judgments made by management in the preparation of these financial statements are difficult and subject to a higher degree of measurement uncertainty during this period. Management continues to monitor the situation and has taken steps to mitigate the likelihood of occurrence of the events described above by managing costs.

In response to the economic slowdown caused by COVID-19, the Government of Canada introduced the Canada Emergency Wage Subsidy, an employer assistance program. For the three months ended June 30, 2021, the Company recognized $6,221 of salary and wage subsidies presented as reductions in project costs, equipment costs and general and administrative expenses of $3,714, $2,025 and $482, respectively. For the six months ended June 30, 2021, the Company recognized $11,997 of salary and wage subsidies presented as reductions of project costs, equipment costs and general and administrative expenses of $7,515, $3,726 and $756 respectively. For the three and six months ended June 30, 2020, the Company recognized $10,728 of salary and wage subsidies presented as reductions in project cost, equipment cost and general and administrative expenses of $5,494, $3,787, and $1,447 respectively.

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 also 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. For clarity, revenues from these investments are not included in consolidated revenue.

12. Subsequent event
On June 9, 2021, the Company announced that it entered into a definitive agreement to acquire DGI Trading Pty Limited (“DGI”), a supplier of production-critical mining components based in Kempsey, New South Wales, Australia, for an estimated purchase price of $23.5 mil ion. The transaction closed subsequent to the reporting period on July 1, 2021 with an initial payment of $10.3 mil ion funded through existing debt facilities.

The Company is in the process of valuing amounts for the major classes of assets and liabilities acquired, intangible assets and pre-acquisition contingencies in order to al ocate the purchase price.
