Letter to Shareholders If you have read any of my previous letters, you wil know that I enjoy using analogies and metaphors to describe our business. For our Q3 performance and going forward, I believe it’s fair to say that we are “rol ing up our sleeves”. The first sleeve we’re rol ing up to get vaccinated so that our workforce can be protected as best we can from the COVID-19 virus. The second sleeve we’re rol ing up to prepare for our busiest season, winter, and to commence work on recent major project wins. I also like the term because it accurately describes the grit and determination I see as common culture in our core business, our partnerships, and even our recent Australian acquisition of DGI (Aust) Trading Pty Ltd. ("DGI").
Starting with DGI, I have been genuinely impressed with our Australian team’s ability to exceed initial expectations. Although early days, the DGI team has shown they can run and grow a global business providing mining components and equipment while operating in one of the strictest, if not the strictest, pandemic lockdowns in the world. The DGI team has continued to purchase, tear down, ship, and sel equipment and components while often being travel restricted to their own state. The strength of relationships with their clients and subcontractors along with their internal skil s in equipment assessments and logistics has DGI producing at pre-pandemic levels. I am real y looking forward to seeing what this team can do when they aren’t running into hurricane headwinds (apologies, I mean “cyclone headwinds”).
In Q3, our other partnerships likewise showed how their grit gained ground against similar headwinds. Our Mikisew North American Limited Partnership ("MNALP") won major new oil sands contracts and extensions, achieving record backlog. MNALP also recommenced long-term overburden work at Fort Hil s and continues to invest in quality second-life Ultra-class trucks rebuilt by NACG. Our Nuna team continues to outperform with our North American Nuna Joint Venture hitting peak operating production at our Ontario Gold project, while closing out a successful summer across the rest of their business. Al of our partnerships are expecting a strong winter program and NACG wil be in up to our elbows with efforts to support and grow our partnerships.
Thankful y, our Q3 financial performance was much more stable than Q2 and the consistency in operating conditions al owed for predictable results. Our operating margins continue to be impacted by the necessary safety protocols in place at the various mine sites, but the impacts were far less severe than last quarter. Equipment utilization reflected effective use of the fleet with higher demand being offset by summer rentals and time required to mobilize between sites. We do not expect any significant fleet relocations for the next year and anticipate increasing utilization as the maintenance invested in our fleet ahead of the winter season should yield improved results. With the solid Q3 performance in the books, we have increased and narrowed the ranges of our 2021 outlook with the improved visibility. Some additional highlights I’d like to briefly note are:
•	Acheson maintenance facility expansion completed last week, on time and on budget. Al four new bays and the heated storage facility are actively being used.
•	Financial close of our Red River flood mitigation project in the United States. Initial key management personnel being hired and relocated to site. Equipment procurement commencing and earthworks to start in Spring.
•	Board approval to 2022 growth capital of ~$3.7M to expand component remanufacturing facility for additional space and hydraulic works (commences in Q4, scheduled to complete Q2 FY2022).
•	Ful rooftop solar panels instal ed with the maintenance facility expansion, now totaling +400,000 kWh annual y or ~15% of total facilities electrical consumption.
•	Telematics instal ed in 73 units and targeting 150 before year end. Mapping and Alert Management is in phase 2 testing. Connections between servers have been made and software instal s have begun. Developing software interface for three different equipment brands.
•	Hydrogen dual fuel project progressing, expecting feasibility study completed in Q4/Q1 with decision for advancing to proof of concept in Q1 FY2022 and decision to advance a prototype before year-end 2022.
Without taking our eye off of this critical Q4, we look to 2022 and have provided our range of outcomes based on the contracts and projects we currently have in place. I am keenly aware of the exciting momentum we feel internal y here at NACG but it real y shows up quantitatively when we look at the estimates for next year. Back in the lows of 2016, the idea of projecting EPS in the range of $2.15 to $2.55 would have been met with extreme skepticism (to say the least). We see the goals ahead of us and are focused on execution.
	i

Regarding capital al ocation, we continue to assess our options in light of market and other macro conditions. We view this 2021 as a recovery-type year and have deferred major capital al ocation decisions including the annual Board review of our dividend plan into Q1 2022 with the simple goal of finishing this year out strong. The free cash flow generation we expect in the quarter provides us with a great deal of flexibility and we wil continue to look to optimize returns for shareholders.
In closing, although share price volatility seems to have subsided, we continue to believe our shares are under-valued and do not reflect the business gains and improvements we have made in regard to growth, diversification, backlog, and sustainability. In true NACG gritty fashion, we expect to change perceptions by raising the bar and continuing to beat expectations. The WWII iconic Rosie the Riveter is a great letter ending metaphor for NACG going forward. She was a great recruiter for women in the workforce, has her sleeves rol ed up like NACG, and one simple slogan …… WE CAN DO IT!
I look forward to sharing our Q4 and year-end results with you in February. Hope you al have a wonderful holiday season and let’s al have a virus free new year.

Management’s Discussion and AnalysisFor the three and nine months ended September 30, 2021
October 27, 2021
The fol owing Management’s Discussion and Analysis ("MD&A") is as of October 27, 2021 and should be read in conjunction with the attached unaudited interim consolidated financial statements and notes that fol ow for the three and nine months ended September 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", "adjusted EBITDA margin", "total combined revenue", "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", "growth capital", "invested capital", "margin", "net debt", "senior debt", "sustaining capital" and "total debt". We provide tables in this document that reconcile non-GAAP measures used to amounts reported on the face of the consolidated financial statements. A summary of our non-GAAP measures is included below under the heading "Non-GAAP financial measures".

Starting with this Q3 Financial Report, we have begun disclosing combined results to more thoroughly reflect the growing contribution from the investments we have in partnerships and joint ventures. The details of these results can be found in note 7 of the financial statements. Moving forward, our intention is for reported revenue to reflect our whol y-owned entities with remaining interests being accounted for in equity earnings. We are confident that this wil improve understanding for the readers of our financial reports.
For the three months ended September 30, 2021, revenue was $166.0 mil ion, up from $93.6 mil ion in the same period last year. The primary drivers of this $72.4 mil ion increase were the re-mobilized equipment fleet at the Fort Hil s mine as wel as a year-over-year step change in demand for mine support work and equipment rentals at the Kearl mine. Our diversification efforts continue to drive positive changes as the July 1, 2021 acquisition of DGI (Aust) Trading Pty Ltd. ("DGI") provided a ful quarter of revenue on target due to a seamless transition and strong global demand for heavy equipment parts and components. Lastly, our external maintenance program completed various projects during the quarter and is gaining back the momentum it had prior to the pandemic.
Equity earnings in the quarter of $6.8 mil ion easily surpassed last year's busy Q3 for Nuna and set another company record for the Nuna Group of Companies. Reflecting this trend, the $43.3 mil ion of revenue included in equity earnings this quarter compared to $25.3 mil ion in Q3 2020. This impressive achievement was driven by the activity at the gold mine in Northern Ontario being completed by the joint venture owned by Nuna and NACG.
Adjusted EBITDA margin of 22.7% reflected stable performance at the various mine sites under consistent predictable operating conditions this quarter. Isolation protocols and vaccination requirements did increase operating costs but the impacts were not nearly as severe as Q2 2021. The margin was impacted by increased equipment maintenance activities to ensure our fleet is operating at ful capacity heading into the winter season. Offsetting these decreases were both the strong performance of the newly awarded scopes at the Fort Hil s mine and the diversified margin profile from parts and component sales by DGI.
Management's Discussion and Analysis							M-2	North American Construction Group Ltd.
September 30, 2021

Free cash flow in the quarter of $10.0 mil ion was generated from EBITDA less sustaining capital expenditures but was noticeably impacted by deferred timing of cash receipts from our various joint ventures which we expect to receive in the normal course.
SIGNIFICANT BUSINESS EVENTS
Credit Facility Amended and Extended
On September 29, 2021, we announced an amendment and extension of our senior secured credit facility (the “Credit Facility”). The facility maturity date has been extended by one year with a new maturity date of October 8, 2024. In addition to the extension of existing favourable terms, amendments have also been incorporated that provide us greater flexibility in operating through joint ventures, including joint ventures related to larger contracts under public-private-partnership financing models.
Contract Award and Extension
On September 14, 2021, we announced a contract award to Mikisew North American Limited Partnership ("MNALP") by a major oil sands producer. The contract extends the existing master service agreement between NACG and the producer to December 2023 as wel as transitioning the contractor role to MNALP. We anticipate the contract to generate approximately $275.0 mil ion in revenue for NACG over the term of the agreement.
Increase in Committed Scope from Contract Amendment
On July 21, 2021, we announced a contract amendment to a multiple use agreement between the MNALP and a major oil sands producer. While the amended agreement retains the expiration date of December 2023, we anticipate our share to be approximately $175.0 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 the 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 of which the majority is expected be earned during the initial six-year construction period. 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. The completion of the financial close for this project was announced on October 14, 2021.
Acquisition of Australian Component Supplier
On June 9, 2021, we announced that we had entered into a definitive agreement to acquire DGI, a supplier of production-critical mining components based in Kempsey, New South Wales, Australia. The transaction closed on July 1, 2021 for a purchase price of $18.4 mil ion with an initial payment of $10.3 mil ion funded through existing debt facilities. The purchase price was approximately equal to the net identifiable 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, we 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, we 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 nine months ended September 30, 2021, we 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 nine months ended September 30, 2021 results
Revenue
For the three months ended September 30, 2021, revenue was $166.0 mil ion, up from $93.6 mil ion in the same period last year. As our customers continue to recover from the initial impacts of COVID-19 and navigate the chal enges presented during the fourth wave of the pandemic, revenue has increased as a result of the continuation of previously delayed work, as wel as an increased demand for our services on new projects. In the quarter, we re-mobilized equipment to the Fort Hil s mine and began completing earthwork, overburden, and heavy civil construction activities, which is expected to continue for the remainder of the year. The suspension of work at the Fort Hil s mine caused a reduction in year-over-year revenue which has returned to a more normalized level in Q3. The demand for mine support work and equipment rental support at the Kearl mine remained strong for the quarter which was complemented by the completion of a haul truck rebuild and a dozer repair through our external maintenance program. Revenue was also positively impacted by the results from the acquisition of the Australian component supplier, DGI Trading.
For the nine months ended September 30, 2021, revenue was $473.1 mil ion, up from $362.4 mil ion in the same period last year. This increase of 30.5% reflects the Q3 increases mentioned above combined with a strong demand for equipment rental support and overburden removal activities at the Mil ennium mine and an expanded winter reclamation program at the Aurora mine. The completion of the overburden and ditch construction work at the Kearl mine and higher volumes of civil construction services awarded at the Mildred Lake mine also positively impacted revenue in the year. These increases were partial y offset by a reduction in winter reclamation work at the Mildred Lake mine.
Gross profit
For the three months ended September 30, 2021, gross profit was $21.7 mil ion, and a 13.1% gross profit margin, up from a gross profit of $14.8 mil ion and down from gross profit margin of 15.8% in the same period last year. The improvement in gross profit in the current period was driven by the increase in site activity as our customers continue to recover from the impacts of COVID-19. The operational impacts of safety protocols and workforce availability are estimated to have impacted gross profit by approximately $3.0 mil ion net of government assistance and wage subsidy programs. The gross profit margin variance year-over-year was impacted by isolation protocols and vaccination requirements related to the pandemic. Additional y, the margin was impacted by increased equipment maintenance activities as we performed services to ensure our fleet is operating at ful capacity for the large demand of work heading into the winter season. Offsetting these decreases were both the strong performance of the newly awarded scopes at the Fort Hil s mine and the diversified margin profile from parts and component sales by DGI.
Q3 2021 results also include $1.4 mil ion of salary and wage subsidies of which $1.3 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. Q3 2020 results include $10.9 mil ion of salary and wage subsidies of which $9.3 mil ion is included in gross profit.
For the nine months ended September 30, 2021, gross profit was $67.4 mil ion, and a 14.2% gross profit margin, down from $69.7 mil ion, and a 19.2% gross profit margin, in the same period last year. The decrease in gross profit is mainly driven by a reduction in site activity in Q1 2021, coupled with the suspension of work at the Fort Hil s mine that began in Q1 2020 and continued until late Q2 2021. The gross profit margin was impacted by the Q3 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 was improved operating efficiency on the civil construction scope at the Mildred Lake Mine Extension project and the strong performance of the newly awarded scopes at the Fort Hil s mine. Our operations support services also positively impacted margin given the nature of those mine management contracts.
Management's Discussion and Analysis	M-6	North American Construction Group Ltd.
September 30, 2021

For the nine months ended September 30, 2021, results include $13.3 mil ion of salary and wage subsidies of which $12.4 mil ion is included in gross profit. In the same period last year, results include $10.9 mil ion of salary and wage subsidies of which $9.9 mil ion is included in gross profit.
For the three months ended September 30, 2021, depreciation was $21.4 mil ion, or 12.9% of revenue, up from $18.8 mil ion, or 20.1% of revenue, in the same period last year. The increase in depreciation is largely due to the increase in utilization of the fleet when compared to the same period last year which was significantly impacted by COVID-19. Depreciation as a percentage of revenue for three months ended September 30, 2021 decreased primarily due to the impacts of revenues not related to equipment utilization. We saw significant increases in revenue related to the acquisition of DGI and external maintenance.
For the nine months ended September 30, 2021, depreciation was $79.0 mil ion, or 16.7% of revenue, up from $62.5 mil ion, or 17.3% of revenue, in the same period last year. The increase in depreciation for the nine months ended September 30, 2021 is driven by the Q3 factors discussed above.
Operating income
For the three months ended September 30, 2021, we recorded operating income of $14.4 mil ion, an increase of $4.9 mil ion from the $9.5 mil ion for the same period last year. General and administrative expense, excluding stock-based compensation expense, was $7.1 mil ion (or 4.3% of revenue) for the quarter, higher than the $3.7 mil ion (or 4.0% of revenue) in the prior year. The increase is driven by lower COVID wage subsidies received in the year. Stock-based compensation expense decreased by $1.8 mil ion compared to the prior year primarily due to the impact of the fluctuating share price on the carrying value of our liability classified award plans.
For the nine months ended September 30, 2021, we recorded operating income of $37.7 mil ion, a decrease of $18.0 mil ion from the $55.7 mil ion for the same period last year. General and administrative expense, excluding stock-based compensation expense was $20.1 mil ion (or 4.2% of revenue) compared to the $16.2 mil ion (or 4.5% of revenue) for the nine months ended September 30, 2020. Stock-based compensation expense increased by $12.9 mil ion compared to the prior year primarily due to the impact of the fluctuating share price on the carrying value of our liability classified award plans.

Total interest expense was $4.8 mil ion during the three months ended September 30, 2021, a slight increase from the $4.4 mil ion recorded in the prior year due to an increase in interest from our convertible debentures, offset by reduced interest in al other categories, largely due to reduced amounts outstanding over the respective periods. During the nine months ended September 30, 2021, total interest expense was $13.8 mil ion, a decrease from the $14.2 mil ion recorded in the prior year. The decrease in the nine months ended September 30, 2021 can be attributed to the lower outstanding balance on our Credit Facility.Cash related interest expense for the three months ended September 30, 2021, calculated as interest expense excluding amortization of deferred financing costs of $0.3 mil ion, was $4.5 mil ion and represents an average cost of debt of 4.3% when factoring in the Credit Facility balances during the quarter (compared to 3.6% for the three months ended September 30, 2020). Cash related interest expense for the nine months ended September 30, 2021 excluding amortization of deferred financing cost of $0.8 mil ion was $13.0 mil ion and represents an average cost of debt of 4.1% (compared to 3.8% for the nine months ended September 30, 2020).
Equity earnings in affiliates and joint ventures of $6.8 mil ion and $16.3 mil ion for the three and nine months ended September 30, 2021, respectively, were generated by Nuna and other various joint ventures consolidated using the equity method. The increase in the three and nine months ended September 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 nine months ended September 30, 2021, we recognized a realized gain of nil and $7.1 mil ion, respectively, (unrealized 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. During the three and nine months ended September 30, 2020, we recognized a net realized and unrealized gain of $0.6 mil ion and $0.8 mil ion, respectively. This swap agreement was completed during the nine months ended September 30, 2021.
We recorded deferred income tax expense of $1.8 mil ion and $6.2 mil ion for the three and nine months ended September 30, 2021, respectively. For the three and nine months ended September 30, 2020, we recorded income tax expense of $3.5 mil ion and $10.5 mil ion, respectively. Income tax expense relates to income excluding equity earnings in affiliates and joint ventures. The income tax amounts in the current year are lower due to the reduced Alberta corporate tax rate and lower earnings in the nine months ended September 30, 2021.
Net income and comprehensive income
For the three months ended September 30, 2021, we recorded $14.0 mil ion of net income and comprehensive income (basic net income per share of $0.49 and diluted net income per share of $0.44), compared to $6.8 mil ion net income and comprehensive income (basic net income per share of $0.23 and diluted net income per share of $0.22) recorded for the same period last year.

Free cash flow of $10.0 mil ion in the quarter was positively impacted by higher profitability offset by changes in working capital balances and balances owed by joint ventures. Positive cash flow of $23.8 mil ion was generated by adjusted EBITDA of $47.5 mil ion offset by sustaining capital additions of $19.8 mil ion and cash interest paid of $4.0 mil ion. Sustaining maintenance expenditures remained consistent with the expectations of the 2021 capital maintenance plan reflecting necessary maintenance in anticipation of our busy winter season.
Free cash flow for the nine months ended September 30, 2021 was $18.9 mil ion driven by strong operating results offset by investments in working capital, capital work in progress and joint ventures. Positive cash flow of $57.8 mil ion was generated by the adjusted EBITDA of $151.0 mil ion, offset by sustaining capital additions of $82.0 mil ion and cash interest paid of $11.3 mil ion. As mentioned, the remaining differences relate to timing as we invest in component inventory and our growing capital rebuild programs. In addition, the various joint ventures we support and invest in general y distribute cash as part of their year-end processes.

Our total contractual obligations of $510.0 mil ion as at September 30, 2021 increased from $498.4 mil ion as at December 31, 2020, primarily as a result of the decrease to amounts outstanding under the Credit Facility of $81.3 mil ion and a decrease to supplier contracts of $6.4 mil ion, offset by an increase in convertible debentures of $100.8 mil ion and an increase to financing obligations of $0.5 mil ion.
We have no off-balance sheet arrangements.
Credit Facility
Our Credit Facility al ows for borrowing under the revolving loan to $325.0 mil ion with the ability to increase the maximum borrowings by an additional $50.0 mil ion subject to certain conditions and permits finance lease debt to a limit of $150.0 mil ion. This facility matures on October 8, 2024, with an option to extend on an annual basis, subject to certain conditions.
As at September 30, 2021, the Credit Facility had borrowings of $145.6 mil ion (December 31, 2020 - $220.0 mil ion) and $4.7 mil ion in issued letters of credit (December 31, 2020 - $0.9 mil ion). At September 30, 2021, our borrowing availability under the Credit Facility was $174.7 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 September 30, 2021, we were in compliance with al Credit Facility covenants. We ful y expect to maintain compliance with our financial covenants during the subsequent twelve-month period.
Debt ratings
On April 1, 2021, S&P Global Ratings ("S&P") reiterated our Company outlook as "stable" and maintained our long-term corporate credit rating at "B+".

Units granted under such plans typical y vest at the end of a three-year term.

As at October 23, 2021, there were 30,002,028 voting common shares outstanding, which included 1,564,813 voting common shares held by the trust and classified as treasury shares on our consolidated balance sheets (30,002,028 common shares, including 1,561,696 common shares classified as treasury shares at September 30, 2021). Additional y, as at September 30, 2021, there were an aggregate of 20,900 vested and unvested options outstanding under our Amended and Restated 2004 Share Option Plan which, in the event of ful vesting and exercise, would result in the issuance of 20,900 common voting shares.

Share purchase program
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 nine months ended September 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.
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 al ows 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 ful disclosure, refer to note 14 in our Financial Statements for September 30, 2021.
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 September 30, 2021:
	September 30,		December 31,
(dol ars in thousands)		2021		2020(i )
Performance obligations per financial statements	$	189,945 $	126,816

(i)See "Non-GAAP Financial Measures".
(i )The prior year amounts are adjusted to reflect a change in accounting policy. See "Accounting Estimates, Pronouncement and Measures".
We recognized $235.0 mil ion of revenue from the backlog during the nine months ended September 30, 2021. Our backlog increased by $301.8 mil ion from December 31, 2020. As at September 30, 2021, we estimate that approximately $62.2 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 $863.7 mil ion as at September 30, 2021, (December 31, 2020 - $190.3 mil ion), resulting in a combined backlog of $1,902.0 mil ion as at September 30, 2021 (December 31, 2020 - $936.0 mil ion).

Non-GAAP financial measures
"Adjusted net earnings" is defined as net 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.
"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.
“Adjusted EBITDA” is defined as adjusted EBIT before the effects of depreciation, amortization and equity investment depreciation and amortization.
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 cash expenditures or requirements for capital expenditures or proceeds from capital disposals;
•	reflect changes in our cash requirements for our working capital needs;
•	reflect interest expense or 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 cash requirements for assets being depreciated 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", or "operating income 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.
"Adjusted EBITDA Margin" and "Adjusted EBIT Margin" are defined as adjusted EBITDA or adjusted EBIT divided by total combined revenue. Management reviews these measures to assess our core operating performance.
"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 adjusted EBITDA margin and provide normalized adjusted EBITDA margin to investors.
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.
Management's Discussion and Analysis	M-17	North American Construction Group Ltd.
September 30, 2021

"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.

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 nine months ended September 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 September 30, 2021, we had 196 salaried employees (September 30, 2020 - 166 salaried employees) and 1,563 hourly employees (September 30, 2020 - 1,231 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 (September 30, 2020 - 82% of the employees).
Existing terms of the col ective bargaining agreement with the International Union of Operating Engineers continue to apply while renewal discussions continue. Dialogue continued throughout Q3 2021 and we are optimistic that the renewal wil be finalized in Q4 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 and into 2022 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.

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.

Interim Consolidated Financial Statements

Notes to Interim Consolidated Financial Statements
For the three and nine months ended September 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, the United States and Australia, 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 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 and its whol y-owned incorporated subsidiaries in Canada, the United States and Australia. Al significant intercompany transactions and balances are eliminated upon consolidation. The Company also holds ownership interest in other corporations, partnerships and joint ventures.
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 during these seasons are most favorable for this type of work. 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.
With the exception of the change in significant accounting policy shown in note 14 and foreign currency translation, the Company has prepared these interim consolidated financial statements on the same basis as its annual consolidated financial statements.
b) 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 goodwil 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 Sheet, with any subsequent changes to fair value recorded in earnings. Acquisition-related costs are expensed when incurred in general and administrative charges.
c) Foreign currency translation
The functional currency of the Company and the majority of its subsidiaries is Canadian Dol ars. Accounts of the Company's Australia-based subsidy, which has an Australian Dol ar functional currency, are translated into Canadian Dol ars 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 (Loss). 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 cash equivalents for the period.

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.

11. 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.

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.

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 have loosened 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 September 30, 2021, the Company recognized $1,419 of salary and wage subsidies presented as reductions in project costs, equipment costs and general and administrative expenses of $870, $449 and $100, respectively. For the nine months ended September 30, 2021, the Company recognized $13,269 of salary and wage subsidies presented as reductions of project costs, equipment costs and general and administrative expenses of $8,238, $4,175 and $856, respectively.

14) Change in significant accounting policy - Basis of presentation
Prior to July 1, 2021, the Company 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, the Company 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 al ows for consistency in the presentation of the Company's investments in affiliates and joint ventures (note 7).
The Company has accounted for the change retrospectively according to the requirements of US GAAP Accounting Standards Codification ("ASC") 250 by restating the comparative periods. The fol owing tables summarize the effect of the change in accounting policy for the current period and prior comparable periods.
