C. OUR BUSINESS

General Development of the Business

2021

On February 2, 2021, we announced the release of our inaugural 2021 Sustainability Report. This report provides the structured framework for environmental, social and governance initiatives moving forward. Future reports will be issued around this time each year and will allow stakeholders to measure progress in a variety of business areas and community programs with increasing rigor and metrics.

In mid-February and effective January 1, 2021, Barry W. Palmer was appointed to the role of Chief Operating Officer. Mr. Palmer brings over 30 years of experience in the heavy construction and mining sectors and has held several key positions within the Company. He has extensive expertise in providing oversight and valuable technical support and has been a vital contributor to our operational excellence and efficiency. Mr. Palmer has strong management and leadership skills and brings a high degree of consistent accountability with a proven track record to back it up.

2020

For the sixth consecutive year, our Total Recordable Incident Rate ("TRIR") in 2020 for the Company was below 0.50, which is considered the industry benchmark for safety excellence.

In January 2020, we opened a newly constructed component rebuild facility on land adjacent to the Acheson maintenance facility and head office. We continue to enhance our internal equipment maintenance capabilities and grow our external equipment maintenance business. This five-bay facility was custom designed with the primary objective of rebuilding used components for heavy equipment in the mining industry. While providing low-cost zero-hour components, the facility also creates much needed capacity in our primary maintenance facility to allow for its intended use of rebuilding and maintaining both our heavy equipment fleet and the fleets of external customers. In addition, the Nuna Group of Companies will be utilizing this facility for its maintenance needs as well as required kitting and logistics activities for projects in northern Canada.

On January 30, 2020, we executed a five-year Management Services Agreement to operate a thermal coal mine in Texas, USA. The transition from the current operator took place in June 2020. This long-term agreement builds on our mine management services offering as did the similar five-year management services agreement of a coal mine in Wyoming, USA which was signed in June 2019.

On October 22, 2020, we announced the award of a major earthworks construction contract at a gold mining project in Northern Ontario. The contract was awarded to a newly formed joint venture owned and operated equally by NACG and Nuna Group of Companies. The two-year project is valued at over $250 million and will occur during the construction phase of the gold mine project. Our work is scheduled to ramp up through Q1 2021, achieve peak volumes in Q3 2021 and be completed in the fall of 2022.

Annual Information Form 2 North American Construction Group Ltd.

Impact of and Response to COVID-19

The global COVID-19 pandemic has had a material and noticeable impact on our operations. Mine and work sites throughout North America have tightened site access and have made decisions based on their specific and unique circumstances. We provide essential services to these sites and, where allowed, have been able to carry-on operations through the adoption of enhanced safety and health monitoring protocols.

We took swift and aggressive measures at the outset of the pandemic to protect our employees, customers and our Company. We implemented several cost reduction measures to reduce our variable and fixed costs, including but not limited to, immediate suspension of production-related spending on impacted mine sites, minimized use of vendor provided maintenance, a reduced work week schedule for administrative staff, a complete halt of all discretionary spending and termination of services deemed non-essential in light of the pandemic. We also reduced sustaining capital maintenance costs by implementing a reduced capital plan for the remainder of the year. We have been able to ease certain of these measures somewhat as the management of pandemic impacts has stabilized to a degree.

Liquidity is critical during times of uncertainty and cash conservation is a key priority for management in weathering the pandemic. Including equipment financing availability, total available capital liquidity of $177.4 million includes total liquidity of $148.0 million as at December 31, 2020 and is primarily based on the borrowing capacity of $325.0 million under our Credit Facility. For comprehensive discussion on liquidity, see the "Liquidity and Capital Resources" section of our annual MD&A.

Financing and Capital Allocation

On March 9, 2020, we announced our intention to commence a normal course issuer bid ("NCIB") to purchase up to 2,300,000 common shares for cancellation. This represented approximately 8.3% of the issued and outstanding common shares as of March 3, 2020. The NCIB commenced on March 12, 2020 and will terminate no later than March 11, 2021.

On April 6, 2020 we fully redeemed our 5.50% convertible debentures due March 31, 2024. The redemption was satisfied through issuance of 4,583,655 voting common shares and all accrued and unpaid interest up to, excluding the redemption date, was paid in cash.

On October 8, 2020 we entered into an amendment to our Amended and Restated Credit Agreement with a banking syndicate led by National Bank Financial Inc. that increased the revolving loan to $325.0 million with the ability to increase the maximum borrowings by an additional $25.0 million, subject to certain conditions. This facility matures on October 8, 2023, with an option to extend on an annual basis. The Credit Facility permits finance lease obligations to a limit of $150.0 million and certain other borrowings outstanding to a limit of $20.0 million.

Officer and Director Changes

On December 16, 2020 we announced the appointment of Joseph Lambert to the position of President and Chief Executive Officer and to the board of directors effective January 1, 2021. Concurrently with Mr. Lambert's appointment, Martin R. Ferron resigned from his position of Chief Executive Officer and assumed the role of Executive Chairman. Jay Thornton did not stand for re-election as a director at the annual general meeting of shareholders held on May 6, 2020.

2019

TRIR in 2019 for the Company was below 0.50, which is considered the industry benchmark for safety excellence.

On June 21, 2019, we executed a five-year Management Services Agreement to operate a thermal coal mine in Wyoming, USA which serves an adjacent power plant. The agreement was part of a structured bankruptcy process and is indirectly supported by a long-term coal supply agreement between the mine owner and the power producer.

In December 2019, the first rebuilds of heavy equipment haul trucks (CAT 793 and 797) from cores were completed in our primary maintenance facility in Acheson.

Annual Information Form 3 North American Construction Group Ltd.

On March 20, 2019, we issued $55.0 million in aggregate principal amount of 5.00% convertible unsecured subordinated debentures which mature on March 31, 2026. Interest is payable semi-annually on March 31 and September 30 of each year, commencing September 30, 2019.

On August 7, 2019, we announced an increase to our dividend policy whereby our regular dividend was increased to $0.16 per common share per year, payable on a quarterly basis, up from $0.08 per year.

On August 8, 2019, we announced the appointments of Maryse C. Saint-Laurent and Kristina E. Williams to our board of directors. William C. Oehmig did not stand for re-election as a director at the annual general meeting of shareholders held on May 1, 2019.

2018

TRIR in 2018 for the Company was below 0.50, which is considered the industry benchmark for safety excellence.

On November 1, 2018, we closed the acquisition of a 49% ownership interest in Nuna Logistics Limited and related companies (collectively the "Nuna Group of Companies" or "Nuna"), a civil construction and contract mining company based in Edmonton, Alberta, for $42.8 million in cash. The acquisition provided the Company with customer, revenue and geographic diversification while also reducing the overall capital intensity of the business. It is proving to be mutually beneficial to both ourselves and Nuna through access to broader equipment fleets, experienced field personnel and expanded services.

On November 23, 2018, we closed the acquisition of a heavy equipment fleet for $198.0 million. The purchase agreement included an initial payment of $150.8 million and the assumption of $12.6 million in finance leases and equipment related promissory notes from the vendor. The expansion of our fleet has enabled us to expand our core service offerings, entering into several term contracts with customers that we otherwise would not have had sufficient equipment to perform without using costlier rental equipment.

In November 2018, we opened our newly constructed $28.0 million Acheson major equipment maintenance and rebuild facility with corporate office attached, just outside of Edmonton, Alberta. The maintenance facility was custom designed to accommodate all sizes of equipment, including the ultra-class 400-ton haul trucks used by us and our clients. The new facility is part of our strategy to enhance our internal equipment maintenance capabilities while also growing our external equipment maintenance business.

In November 2018, we entered into a newly formed partnership, the Mikisew North American Limited Partnership ("Mikisew partnership"), to provide construction and mining services to our oil sands customers. Our partner, the Mikisew Group of Companies, is directly owned by the Mikisew Cree First Nation.

On November 23, 2018, concurrent with the closing of the acquisition of a heavy equipment fleet, we entered into an upsized Amended and Restated Credit Agreement (the "Credit Facility") with our banking syndicate led by National Bank Financial Inc. The Credit Facility is consistent with previously existing terms, maintains attractive rates and provides sufficient flexibility to allow for significant heavy construction equipment fleet acquisition, including the transaction that closed on the same day. The Credit Facility provides borrowings of up to $300.0 million with an ability to increase the maximum borrowings by an additional $50.0 million, subject to certain conditions (an increase from the $140.0 million borrowing available under the previous facility). The facility matures on November 23, 2021, with an option to extend on an annual basis. The Credit Facility also allows for a finance lease limit of $150.0 million (an increase from the $100.0 million limit under the previous facility) and other borrowings of $20.0 million.

In November 2018, we entered into a 25-year mortgage with the Business Development Bank of Canada for $19.9 million, which was drawn to cover costs already incurred in relation to our recent acquisition of land and the related construction of the Acheson, Alberta maintenance facility and corporate office.

On September 10, 2018, Jason W. Veenstra was appointed to our Management team as Executive Vice President and Chief Financial Officer. On November 28, 2018, Barry W. Palmer became Senior Vice President, Operations, Jordan A. Slator became Vice President and General Counsel and David G. Kallay became Vice President, Health, Safety, Environment and Human Resources.

Business Overview

We provide a wide range of mining and heavy civil construction services to customers in the resource development and industrial construction sectors, primarily within western Canada but also in other parts of Canada and the United States. Our services are primarily focused on supporting the construction and operation of surface mines. We are considered to be a “first-in, last-out” service provider because we provide services through the entire

Annual Information Form 4 North American Construction Group Ltd.

lifecycle of projects. Our work typically begins with the initial consulting services provided during the planning phase, including a review of constructability, engineering and budgeting. This leads into the construction phase during which we provide an expanded range of services, including clearing, muskeg removal, site preparation, underground utility installation and mine infrastructure construction, including construction of tailings ponds, access roads, stabilized earth walls and earth dams. As our mining customers move into mine production, we support the preparation of the mine by providing ongoing site maintenance and upgrading, equipment and labour supply, overburden removal, material hauling and land reclamation.

Our core market remains the Canadian oil sands, where we provide construction and operations support services through all stages of the mine's lifecycle. We have extensive construction experience in both mining and heavy civil projects. Our services are typically provided pursuant to non-exclusive master service agreements or multiple use agreements that set out contractual terms over three-to-five year periods. At present we have such agreements, with existing terms expiring between 2021 and 2024, with Suncor Energy Services Inc. for its Base Mine Millennium and North Steepbank projects, Fort Hills Energy LP for its Fort Hills Mine, Syncrude Canada for its Mildred Lake Mine and Aurora Mine, Imperial Oil Limited for its Kearl Mine and Canadian Natural Resources Limited for its Horizon Mine. These agreements do not necessarily guarantee any particular volume of work, but we have had recent success in securing a significant volume of committed work under several of them (see the “Backlog” section of our annual MD&A, which section is expressly incorporated by reference into this AIF). Historically, we have been able to renew or renegotiate our master service agreements and multiple use agreements with major producers as they expire. We don’t anticipate that changing, as production at commissioned mines continues to operate at a steady state and expected life-of-mine projections at the major sites averages over 30 years of remaining life.

In addition to our construction services, we also provide heavy equipment maintenance, component remanufacturing and rebuild services to mining companies and other heavy equipment operators. Our maintenance personnel have specialized skills in working with equipment subjected to the difficult operating conditions of the mining industry. Those specialized skills, combined with our new purpose-built facilities, provide us with the ability to provide a high level of maintenance services in a cost effective manner to our external customers. While the heavy equipment maintenance portion of our business is currently relatively small, we intend to grow that business over the next few years.

We have a 49% ownership interest in the Nuna Group of Companies. Nuna’s revenue relates to commodities such as base metals, precious metals and diamonds as well as infrastructure-related projects that involve major earthworks. Nuna is a well-established incumbent contractor in Nunavut and the Northwest Territories and successfully completed major projects in Ontario, Saskatchewan and British Columbia. Nuna’s peak business activity occurs during the summer months generally from June to September.

Fleet and Equipment

As of December 31, 2020, we directly operated a heavy equipment fleet of 626 units; 68% were owned, 28% were leased and 4% were rented. This fleet is supported by over 1,450 pieces of ancillary equipment. In addition to this, the joint ventures we operate have a combined owned fleet of approximately 270 pieces of heavy equipment.

We have a modern, well-maintained fleet of equipment to service our clients' needs. We operate a significant number of trucks larger than 240 tons in capacity which gives us a distinct advantage over competitors with respect to both specialized skill base and equipment availability. The size and diversity of our fleet gives us the ability to respond on short notice and provide customized fleet solutions for each specific job. Our equipment strategy allows us to meet our customers' variable service requirements while balancing the need to maximize equipment utilization.

As of December 31, 2020, our owned and leased fleet (excluding rentals) is comprised of the following categories:

Competitive Conditions

Much of our business is secured through the formal competitive bidding process.Our competitive environment and customer behavior have continued to remain focused on lowering costs and getting the best value for their dollar. As the oil sands region struggles with lack of pipeline capacity and production cuts to crude output, oil sands operators continue to focus on controlling costs. Some of our customers have also taken a different approach to contracting on their sites and have embarked on contractor consolidation, signing of longer-term agreements with committed volumes to ensure safe and cost-conscious execution certainty. Due to the impacts of the COVID-19 pandemic, competition for new projects is significant for project tenders, especially for those involving smaller and mid-sized fleets, with numerous bidders invited and participating.

The market outside of the oil sands remains equally competitive. Our customers continue to increase the number of competitors on their bid lists in efforts to achieve lower pricing. In some cases, we are seeing willingness from the customer to entertain alternate pricing arrangements such as “risk/reward” agreements where the customer is willing to share in some of the risks, provided there are corresponding costs savings to warrant taking on such risks.

Our excellent safety record, combined with our significant mining and heavy construction knowledge, experience, long-term customer relationships, equipment capacity and scale of operations, differentiate us from our competition and provide significant value to our customers. We believe we are the premier provider of contract mining services and heavy civil earthworks. We have operated in western Canada for over 65 years and have participated in every significant oil sands mining project since operators first began developing this resource over 40 years ago. This participation has given us extensive experience operating in the challenging working conditions created by the harsh climate and difficult terrain of the oil sands and northern Canada. We have amassed what we believe is the largest heavy civil construction and mining fleet of equipment in Canada. The combination of our significant size and extensive experience makes us one of only a few companies capable of taking on long-term, large-scale mining and heavy civil construction projects, both in the oil sands and in other remote resource development locations. This competitive advantage supports successfully providing similar services to large-scale earthworks infrastructure and resource development projects in both Canada and the United States.

Major Suppliers

We have long-term relationships with the following suppliers of equipment, parts and components:

•Finning International Inc. (over 50 years), the Caterpillar heavy equipment supplier in Alberta for the majority of our mining fleet, including repair parts;

•Wajax Corporation (over 25 years), the supplier of our mining and construction Hitachi excavators and shovels;

•Brandt Tractor Ltd. (over 35 years), the Alberta supplier for our construction John Deere excavators;

•SMS Equipment Inc. (over 10 years), the Canadian supplier of a large capacity fleet of our Komatsu mining trucks;

•Brake Supply Inc. (over 10 years), our prime supplier of Caterpillar powertrain components, Hydraulic cylinders for our Caterpillar mining equipment, fleet of Haul Trucks ranging in carrying capacity from 100 tonnes to 400 tonnes, and for Dozers D8T to D11T models.

•Hydraulic Repair and Design (over 10 years), our prime supplier of hydraulic cylinders and pumps for our Hitachi mining shovels and excavators;

•SRC of Lexington (3 years), our prime supplier of Caterpillar re-manufactured engines for our Caterpillar mining fleet of Haul Trucks ranging in carrying capacity from 100 tonnes to 240 tonnes, and for Dozers D10T and D11T models.

•Imperial Oil (over 15 years), our prime supplier of lubricants for our mining and mobile equipment fleets.

Annual Information Form 6 North American Construction Group Ltd.

Finning, Wajax, Brant and SMS are also major suppliers for equipment rentals and service labour.

We continue to work with all of our suppliers to identify shared cost savings opportunities, including opportunities to extend vendor parts reliability programs, leverage their parts supply chain, improve the cost effectiveness of vendor supplied maintenance services and reduce costs for rental equipment.

We have a tire agreement and allocations with Bridgestone (Kal Tire) along with additional tire availability from Michelin and Goodyear which have allowed us to maintain tire inventories required to keep our fleet fully operational. Our tire inventory and availability from the manufacturers is such that we do not anticipate any tire shortages. However, as the global mining and commodities markets strengthen, tire supply can be negatively affected by natural disasters, raw material shortages or unscheduled interruptions from global production facilities.

Seasonality

Oil sands mine support revenue during the December to March time period of each year is traditionally highest as ground conditions are most favorable for work requiring frozen ground access. We generally experience a seasonal decline in our oil sands mine site support revenue, such as reclamation and muskeg removal services, during the three months ended June 30 of each year as weather conditions make performance of this heavy equipment intensive work difficult during this period. Mine support activities for resource mines outside the oil sands typically are at their peak during the May to October time period, contrary to the seasonality of an oil sands mine that relies on the cold winter season for effective material movement. The exact timing of the winter freeze or spring thaw in any given year obviously affects the exact timing of this cyclical and counter-cyclical work cycle. For further discussion of the seasonality of our business, see our MD&A for the year ended December 31, 2020.

Health, Safety and Environmental

While environmental permitting and compliance with respect to the projects and sites on which we operate is generally the responsibility of our customers, our operations and business are subject to various federal, provincial, state and municipal legislation and regulation in relation to health, safety and the environment in all of the jurisdictions in which we operate. Beyond our commitment to meet statutory and regulatory requirements, our commitment to health, safety and environmental responsibility is of utmost priority to us. We are committed to conducting our business in such a manner as to protect and preserve the health and safety of our employees, contractors and the public as well as the safety of the environment.

The Company has implemented an Environment Code that establishes specific environmental management procedures and protocols that all employees, contractors and management personnel must undertake and comply with at all times, including the requirement for the Company and every contractor to establish waste management plans for every project. Among other things, the Environment Code addresses and sets standards and procedures for: (a) collection, handling, storage, recycling and disposal of waste, including hazardous and non-hazardous waste; (b) prevention, containment and cleanup of spills and leaks of hazardous materials or anything that may cause groundwater contamination; (c) water management and testing; (d) soil management and testing; (e) management of controlled products; (f) noise and energy monitoring and management; (g) storm water contamination prevention; (h) erosion prevention and sedimentary control; (i) air pollution prevention and control; (j) training in relation to the matters dealt with by the Environment Code; and (k) periodic audits to ensure compliance with the Environment Code.

At each work site, we develop and implement detailed health, safety and environmental plans as the primary tool to demonstrate and maintain compliance with all applicable regulations and conditions of permits and approvals as well as the Company's Environment Code. All employees at a supervisor role or higher are required to complete on an annual basis health, safety and environmental training. In addition, our Code of Conduct and Ethics Policy (the “Code”) identifies health, safety and environmental responsibility as fundamental corporate values. The Code requires that every employee, officer, director, representative and agent of the Company: (a) maintain a safe and healthy workplace for all Company personnel by following health and safety rules and practices instituted by the Company and by reporting accidents, injuries and unsafe equipment, practices or conditions; (b) be accountable for their own health and safety and have a responsibility towards maintaining the health and safety of those with whom they work; (c) report fit for work such that the ability to work safely is not impaired by alcohol, drugs, medications or any other substance; (d) continually improve environmental performance through the implementation of effective systems and the use of technology; (e) ensure that all Company personnel understand NACG’s commitment to and their role in NACG’s environmental performance; (f) conserve natural resources, minimize waste and promote recycling; (g) meet the expectations of our employees, customers, government, regulatory bodies and the community in relation to environmental responsibility; and (h) comply with the environmental policies of our customers while working on their sites.

Annual Information Form 7 North American Construction Group Ltd.

Employees are required to report any safety or environmental concerns or violations to their supervisor, to the Company’s Human Resources department, to the senior officers of the Company or to any member of the Company’s board of directors, or where anonymity is desired, through the Company’s anonymous ethics reporting system. Any issues raised are included in quarterly reports which are provided to the senior management team and the board of directors. Senior management also receives a weekly report setting out any health, safety or environmental incidents in the previous week and any steps taken or suggested to be taken in order to prevent future incidents.

Employees and Labour Relations

As at December 31, 2020, we had 176 salaried employees (2019 - 186 salaried employees) and approximately 1,499 hourly employees (2019 - 1,738 hourly employees) in our western Canadian operations (excluding 273 active employees employed by the Nuna Group of Companies in 2020 and 331 in 2019). Of the hourly employees, approximately 86% of the employees are union members and work under collective bargaining agreements (December 31, 2019 - 84% of the employees). 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.

The majority of our work is carried out by employees governed by our mining 'overburden’ collective bargaining agreement with the International Union of Operating Engineers ("IUOE") Local 955, which ensures labour stability through to May 2021. Collective bargaining negotiations have commenced for renewal of the overburden agreement with a united goal, between contractors and the IUOE, to have a ratification vote by April 2021.

A collective agreement specific to work performed in our Acheson facilities between the IUOE and North American Maintenance Ltd. is in place until February 2023.

Our relationship with all our employees, both union and non-union, is strong and we have not experienced a union labour disruption since the inception of our collective agreements.

Debt Ratings

On March 10, 2020, S&P Global Ratings ("S&P") changed our company outlook from "positive" to "stable" and upgraded our long-term corporate credit rating to "B+" from "B". S&P changed the outlook to reflect the view that we generated strong cash flows and credit measures in 2019, demonstrating successful integration of the 2018 acquisitions.

An obligation rated "B" is regarded by S&P as having speculative characteristics, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to meet its financial commitment on the obligation. The ratings from "AA" to "CCC" may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within S&P's major rating categories.

An S&P rating outlook assesses the potential direction of a long-term credit rating over the intermediate term (typically nine months to two years). In determining a rating outlook, consideration is given to any changes in the economic and/or fundamental business conditions. An outlook is not necessarily a precursor of a rating change or future CreditWatch action. A Stable outlook means that a rating is not likely to change. A Negative outlook means that a rating may be lowered. A Developing outlook means there is a one-in-three chance the rating could be raised or lowered during the two-year outlook horizon.

A credit rating is a current opinion of the credit worthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the credit worthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion evaluates the obligor's capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default. A credit rating is not a statement of fact or recommendation to purchase, sell, or hold a financial obligation or make any investment decisions nor is it a comment regarding an issuer's market price or suitability for a particular investor. A credit rating speaks only as of the date it is issued and can be revised upward or downward or withdrawn at any time by the issuing rating agency if it decides circumstances warrant a revision. Definitions of the categories of each rating and the factors considered during the evaluation of each rating have been obtained from S&P's website. We paid fees to S&P Global Ratings in order to obtain rating information.

Counterparties to certain agreements may require additional security or other changes in business terms if our credit ratings are downgraded. Furthermore, these ratings are required for us to access the public debt markets, and they affect the pricing of such debt. Any downgrade in our credit ratings from current levels could adversely affect our long-term financing costs, which in turn could adversely affect our ability to pursue business opportunities.

Corporate Cease Trade Orders, Bankruptcies, Penalties or Sanctions

Ronald McIntosh was a director of Forteleza Energy Inc. (“Forteleza”) formerly known as Alvopetro Inc. (“Alvopetro”) from November of 2009 to January of 2016. On March 2, 2011, the Court of Queen's Bench of Alberta granted an order (the “Order”) under the Companies' Creditors Arrangement Act (Canada) ("CCAA") staying all claims and actions against Forteleza and its assets and allowing Forteleza to prepare a plan of arrangement for its creditors if necessary. Forteleza took such steps in order to enable Forteleza to challenge a reassessment issued by the Canada Revenue Agency (“CRA”). As a result of the reassessment, if Forteleza had not taken any action, it would have been compelled to immediately remit one half of the reassessment to the CRA and Forteleza did not have the necessary liquid funds to remit, although Forteleza had assets in excess of its liabilities with sufficient liquid assets to pay all other liabilities and trade payables.

Forteleza believed that the CRA's position was not sustainable and vigorously disputed the CRA's claim. Forteleza filed a Notice of Objection to the reassessment and on October 20, 2011 announced that its Notice of Objection was successful, CRA having confirmed there were no taxes payable. As the CRA claim had been vacated and no taxes or penalties were owing Forteleza no longer required the protection of the Order under the CCAA and on October 28, 2011 the Order was removed. On March 3, 2011, the TSX suspended trading in the securities of Forteleza due to Forteleza having been granted a stay under the CCAA. In addition, the securities regulatory authorities in Alberta, Ontario and Quebec issued a cease trade order with respect to Forteleza for failure to file its annual financial statements for the year ended December 31, 2010 by March 31, 2011. The delay in filing was due to Forteleza being granted the CCAA order on March 2, 2011 and the resulting additional time required by its auditors to deliver their audit opinion. The required financial statements and other continuous disclosure documents were filed on April 29, 2011 and the cease trade order was subsequently removed. On September 1, 2010 Forteleza closed the sale of substantially all of its oil and gas assets. As a result of the sale Forteleza was delisted from the TSX on March 30, 2011 as it no longer met minimum listing requirements.

John Pollesel is a director of First Cobalt Corporation (“First Cobalt”). First Cobalt announced on June 21, 2017 that it had proposed a friendly merger with Cobalt One Ltd. (“Cobalt One”) and CobalTech Mining Inc. (“CobalTech”). At that time, First Cobalt signed letters of intent with each of Cobalt One and CobalTech and requested the TSX Venture Exchange to temporarily halt trading of its shares. The TSX Venture Exchange approved the resumption of trading as of August 28, 2017.

Interest of Management and Others in Material Transactions

No director or executive officer of the Company and, to the knowledge of the directors and executive officers of the Company, none of their respective associates or affiliates, nor any person who owns, controls or directs, directly or indirectly, more than 10 percent of our outstanding voting common shares, nor their respective associates or affiliates, has had any material interest, direct or indirect, in any transaction within our three most recently completed financial years or during our current financial year that has materially affected or is reasonably expected to materially affect us.

G. FORWARD-LOOKING INFORMATION, ASSUMPTIONS AND RISK FACTORS

Forward-Looking Information

This document contains forward-looking information that is based on expectations and estimates as of the date of this document. Our forward-looking information is information that is subject to known and unknown risks, uncertainties, assumptions and other factors that may cause future actions, conditions or events to differ materially from the anticipated actions, conditions or events expressed or implied by such forward-looking information including those listed in the “Forward-Looking Information, Assumptions and Risk Factors” section of our annual MD&A, which section is expressly incorporated by reference into this AIF. Forward-looking information is information that does not relate strictly to historical or current facts and can be identified by the use of the future tense or other forward-looking words such as “believe”, “expect”, “anticipate”, “intend”, “plan”, “estimate”, “should”, “may”, “could”, “would”, “target”, “objective”, “projection”, “forecast”, “continue”, “strategy”, “intend”, “position” or the negative of those terms or other variations of them or comparable terminology.

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

1.Our expectations regarding timing of work in relation to the major earthworks construction contract at a gold mining project in Northern Ontario;

2.Our anticipation that we will be able to renew or renegotiate our master service agreements and multiple use agreements with major producers as they expire;

3.Our intention to grow the heavy equipment maintenance portion of our business over the next few years;

4.Our anticipation that we will not experience any tire shortages in the foreseeable future;

5.Our expectations that the seasonality of oil sands mine support revenues and non-oil sands mine support revenues will continue respectively as they have in the past;

6.Our expectations of labour stability; and

7.Our anticipation that our dividend policy will not change in the foreseeable future.

While we anticipate that subsequent events and developments may cause our views to change, we do not have an intention to update this forward-looking information or the forward-looking information and related risks, assumptions or other information expressly incorporated by reference into this AIF, except as required by applicable securities laws. Such forward-looking information represents our views as of the date of this document and such information should not be relied upon as representing our views as of any date subsequent to the date of this document. We have attempted to identify important factors that could cause actual results, performance or achievements to vary from those current expectations or estimates expressed or implied by the forward-looking information. However, there may be other factors that cause results, performance or achievements not to be as expected or estimated and that could cause actual results, performance or achievements to differ materially from current expectations. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those expected or estimated in such statements. Accordingly, readers should not place undue reliance on forward-looking information. These factors are not intended to represent a complete list of the assumptions and factors that could affect us. See “Assumptions” and “Risk Factors” below and risk factors highlighted in materials filed with the securities regulatory authorities filed in the United States and Canada from time to time, including, but not limited to, our most recent annual MD&A, which section is expressly incorporated by reference in this AIF.

Annual Information Form 17 North American Construction Group Ltd.

Assumptions

For a description of assumptions, see the “Assumptions” section of our annual MD&A, which section is expressly incorporated by reference into this AIF.

Risk Factors

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

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

•Unit-price Contracts.Approximately 47%, 52% and 62% of our revenue for the years ended December 31, 2020, 2019 and 2018, respectively, was derived from unit-price contracts and, to a lesser degree, lump-sum contracts. Unit-price contracts require us to guarantee the price of the services we provide and thereby potentially expose us to losses if our estimates of project costs are lower than the actual project costs we incur and contractual relief from the increased costs is not available. The costs we actually incur may be affected by a variety of factors including those that are beyond our control, such as:

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

•the availability and cost of skilled workers;

•the availability and proximity of materials;

•unfavorable weather conditions hindering productivity;

•equipment availability, productivity and timing differences resulting from project construction not starting on time; and

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

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

•Customer Concentration. Most of our revenue comes from the provision of services to a small number of major oil sands mining companies. Revenue from our four largest customers represented approximately 96% and 95% of our total revenue for the years ended December 31, 2020 and 2019, respectively, and those customers are expected to continue to account for a significant percentage of our revenues in the future. If we lose or experience a significant reduction of business or profit from one or more of our significant customers, we may not be able to replace the lost work or income with work or income from other customers. Certain of our long-term contracts can allow our customers to unilaterally reduce or eliminate the work that we are to perform under the contract. Additionally, certain contracts allow the customer to terminate the contract without cause with minimal or no notice to us. The loss of or significant reduction in business with one or more of our major customers could have a material adverse effect on our business and results of operations.

•Cashflow, Liquidity and Debt. As of December 31, 2020 we had $429.5 million of total debt outstanding. While we have achieved a significant improvement in the flexibility to borrow against our borrowing capacity and a reduction in the cost of our debt over the past three years, our current indebtedness may:

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

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

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

Annual Information Form 18 North American Construction Group Ltd.

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

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

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

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

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

•Labour Disputes. The majority of our hourly employees are subject to collective bargaining agreements to which we are a party or are otherwise subject. Any work stoppage resulting from a strike or lockout could have a material adverse effect on our business, financial condition and results of operations. In order to minimize this risk, NACG has no strike and no lockout provision in our collective agreements. In addition, our customers employ workers under collective bargaining agreements. Any work stoppage or labour disruption experienced by our key customers could significantly reduce the amount of our services that they need.

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

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

•Equipment Utilization. Our business depends on our fleet being operable and in ready-to-work condition. We often operate in conditions that inflict a high degree of wear on our equipment. If we are unable to maintain our

Annual Information Form 19 North American Construction Group Ltd.

fleet so as to obtain our planned utilization rates, or if we are required to expend higher than expected amounts on maintenance or to rent replacement equipment at high rates due to equipment breakdowns, our operating revenues and profits will be adversely impacted. We endeavor to mitigate these risks through our maintenance planning and asset management processes and procedures, though there is no assurance that we can anticipate our future equipment utilization rates with certainty.

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

•Foreign Exchange. We regularly transact in foreign currencies when purchasing equipment and spare parts as well as certain general and administrative goods and services. As such, we are exposed to the risk of fluctuations in foreign exchange rates. These exposures are generally of a short-term nature and the impact of changes in exchange rates has not been significant in the past. We may fix our exposure in either the Canadian dollar or the US dollar for these short-term transactions, if material.

•Internal Controls. Ineffective internal controls over financial reporting could result in an increased risk of material misstatements in our financial reporting and public disclosure record. Inadequate controls could also result in system downtime, give rise to litigation or regulatory investigation, fraud or the inability to continue our business as presently constituted. We have designed and implemented a system of internal controls and a variety of policies and procedures to provide reasonable assurance that material misstatements in the financial reporting and public disclosures are prevented and detected on a timely basis and that other business risks are mitigated. See the section entitled “Internal Systems and Processes” in our MD&A for further details.

•Health and Safety. We are subject to, and comply with, all health and safety legislation applicable to our operations. We have a comprehensive health and safety program designed to ensure our business is conducted in a manner that protects both our workforce and the general public. Despite our past success, there can be no guarantee that we will be able to maintain our high standards and level of health and safety performance. An inability to maintain excellent safety performance could adversely affect our business by customers reducing existing work in response and by hampering our ability to win future work.

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

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

•Heavy Equipment Demand. As our work mix changes over time we adjust our fleet to match anticipated future requirements. This involves both purchasing and disposing of heavy equipment. If the global demand for

Annual Information Form 20 North American Construction Group Ltd.

mining, construction and earthworks services is reduced, we expect that the global demand for the type of heavy equipment used to perform those services would also be reduced. While we may be able to take advantage of reduced demand to purchase certain equipment at lower prices, we would be adversely impacted to the extent we seek to sell excess equipment. If we are unable to recover our cost base on a sale of excess heavy equipment, we would be required to record an impairment charge which would reduce net income. If it is determined that market conditions have impaired the valuation of our heavy equipment fleet, we also may be required to record an impairment charge against net income.

•Integration. There can be no assurance that we will maximize or realize the full potential of any of our acquisitions. A failure to successfully integrate acquisitions and execute a combined business plan could materially impact our financial results.

•Price Escalators. Our ability to maintain planned project margins on longer-term contracts with contracted price escalators is dependent on the contracted price escalators accurately reflecting increases in our costs. If the contracted price escalators do not reflect actual increases in our costs, we will experience reduced project margins over the remaining life of these longer-term contracts. In strong economic times, the cost of labour, equipment, materials and sub-contractors is driven by the market demand for these project inputs. The level of increased demand for project inputs may not have been foreseen at the inception of the longer-term contracts with fixed or indexed price escalators resulting in reduced margins over the remaining life of the longer-term contracts.

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

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

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

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

Annual Information Form 21 North American Construction Group Ltd.

climate change laws and regulations could result in penalties or reputational damage that may impair our prospects.

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

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

•Risk Factors Related to COVID-19. While markets and economies have somewhat stabilized as governments and industry have implemented measures to mitigate the impacts of the pandemic, the situation continues to evolve. Should the pandemic worsen, we could be subject to additional or continued adverse impacts, including, but not limited to restrictions or limitations on the ability of our employees, contractors, suppliers and customers to conduct business due to quarantines, closures or travel restrictions, including the potential for deferral or cessation of ongoing or planned projects. The ultimate duration and magnitude of the pandemic and its financial effect on us is not known at this time. We are continuously monitoring the situation, however, and working with our customers and suppliers to mitigate its effects.

As required by US GAAP, we review our long-lived assets, including property, plant and equipment and identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We detected impairment indicators at March 31, 2020, as a result of the recent uncertainty in the economic environment, relating to the suppression of commodity prices combined with the impact of the COVID-19 pandemic. We completed an impairment test comparing the net carrying value of our long-lived assets to the estimated undiscounted net cash flows to be generated from use of those assets and concluded that they are recoverable and, as such, no impairment was recorded. At December 31, 2020, there were no indicators, as there had been no material declines in the operating environment or expected financial results as compared to March 31, 2020.

As required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Company confirms that its wholly-owned subsidiary NACG Wyoming, Inc. has, since June 21, 2019, been the operator of a coal mine located in southwest Wyoming known as the Kemmerer Mine (the "Mine"). During the period of the Company's operation of the Mine in 2020, the Company received, with respect to the Mine: (a) 28 citations from the Mine Safety and Health Administration (the "MSHA") under Section 104 of the Federal Mine Safety and Health Act of 1977 (30 U.S.C. 814) (the "Act"); (b) no orders under Section 104(b) of the Act; (c) no orders under Section 104(d) of the Act; (d) no flagrant violations under Section 110(b)(2) of the Act; and (e) no imminent danger orders under Section 107(a) of the Act. The total value of proposed assessments from the MSHA relating to violations under the Act in relation to the Mine in 2020 was $7,842 US. There were no fatalities at the Mine in 2020. The MSHA has not provided any notice with respect to the Mine of a pattern of violations, or the potential to have a pattern of violations, of mandatory health or safety standards that could have significantly and substantially contributed to the cause and effect of health or safety hazards under Section 104(e) of the Act. There is no pending legal action before the federal Mine Safety and Health Review Commission involving the Mine.

As required by Section 1503 (a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the company confirms that its wholly-owned subsidiary NACG Texas Inc. has since June 21, 2020, been the operator of a coal mine located in Texas as the San Miguel Mine (the"Mine").

One citation was initially written as a Significant and Substantial (S&S) citation. This has been adjusted by the MSHA inspector to a non S&S; however, it is still listed under MSHA as significant and substantial citation. The Citation and Assessment Office in MSHA acknowledge the citation was changed and we are not being held accountable for not paying the citation within the time frame required. The total value of proposed assessments from the MSHA relating to violations under the Act in relation to the Mine in 2020 was $1,656.00 US. This will decrease to $861.00 US after MSHA adjusts the severity of the Significant and Substantial citations. There were no fatalities at the Mine in 2020. MSHA has not provided any notice with respect to the Mine of a pattern of violations, or the potential to have a pattern of violations, of mandatory health or safety standards that could have significantly and substantially contributed to the cause and effect of health or safety hazards under Section 104(e) of the Act. The mine received one significant and substantial citation; however, it has been reviewed and adjusted by the MSHA inspector to a non-significant and substantial citation. There is no pending legal action before the federal Mine Safety and Health Review Commission involving the Mine.
