C. OUR BUSINESS

General Development of the Business

2020

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. 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 is underway with the formal handover expected in June 2020. This long-term agreement builds on our mine management offering as did the similar five-year management services agreement of a coal mine in Wyoming, USA which was signed in June 2019.

2019

Total Recordable Incident Rate ("TRIR") in 2019 for the Company was again below 0.5, indicating top decile safety management performance.

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.

Financing

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. The annual interest rate of 5.00% is payable semi-annually on March 31 and September 30 of each year, commencing September 30, 2019.

Dividends

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

Officer and Director Changes

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

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 provides 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

Annual Information Form 2 North American Construction Group Ltd.

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.

Financing

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 borrowing 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.

Officer and Director Changes

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.

2017

On April 1, 2017, we entered into a partnership agreement with Dene Sky Site Services Ltd. ("Dene Sky"), a private First Nations business based in Janvier, Alberta. Through a wholly owned subsidiary, we hold a 49% interest in the partnership while Dene Sky holds a 51% interest.

During 2017, we expanded our service offerings to include heavy equipment maintenance for our customers. Maintenance has become one of our core competencies and customers are trending towards rebuilding existing equipment rather than buying new.

Financing

On March 15, 2017, we issued $40.0 million in aggregate principal amount of 5.50% convertible unsecured subordinated debentures which mature on March 31, 2024. The annual interest rate of 5.50% is payable semi-annually on March 31 and September 30 of each year, commencing September 30, 2017.

On August 1, 2017, we entered into a new credit facility agreement with a banking syndicate led by National Bank Financial Inc., replacing our previous Sixth Amended and Restated Credit Agreement (the "Previous Credit Facility"). The new facility provided borrowings of up to $140.0 million with an ability to increase the maximum borrowings by an additional $25.0 million, subject to certain conditions (an increase from the $70.0 million revolver and $30.0 million term loan of the Previous Credit Facility). The facility allowed for a finance lease limit of $100.0 million (an increase from the $90.0 million limit under the Previous Credit Facility).

Officer and Director Changes

On November 23, 2017, we announced the appointment of John J. Pollesel to our board of directors. On October 31, 2017, Martin R. Ferron assumed the role of Chairman of the Board, in addition to his role as Chief Executive Officer, taking over from Ronald A. McIntosh who stepped down from his Chairman role. On the same date, Joseph C. Lambert assumed the role of President in addition to that of Chief Operating Officer, taking over from Martin R. Ferron who stepped down from his President role and Bryan D. Pinney assumed the role of Lead Director of the Board.

Annual Information Form 3 North American Construction Group Ltd.

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 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 is the Canadian oil sands, where we provide construction and operations support services through all stages of an oil sands project's lifecycle. We have extensive construction experience in both mining and in situ oil sands projects and have been providing operations support services to five producers currently mining bitumen in the oil sands since the inception of their respective 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 2020 and 2023, 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 in the region continues to operate at a steady state and expected run-of-mine projections at the major sites averages over 30 years of remaining life.

Our work in the oil sands occurs year-round, though it tends to peak during the winter months when muskeg is frozen and can be more efficiently moved, with work typically slowing somewhat in the summer months. A consequence of that is that our business is also affected by the timing of spring thaw and autumn freeze in the oil sands region, with the spring thaw usually being the most variable. That variability can affect the timing of our revenues, particularly in the third quarter. Our non-oil sands business is less affected by such seasonality.

In addition to our construction services, we also provide heavy equipment maintenance 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 oil sands. 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.

In late 2018, we completed the acquisition of a 49% ownership interest in the Nuna Group of Companies. Nuna’s revenue is entirely outside of the Fort McMurray region, with its focus being on 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 and slows in the winter.

Fleet and Equipment

As of December 31, 2019, we directly operated a heavy equipment fleet of 686 units; 57% were owned, 32% were leased and 11% 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 over 150 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 competitive 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

Annual Information Form 4 North American Construction Group Ltd.

strategy allows us to meet our customers' variable service requirements while balancing the need to maximize equipment utilization.

As of December 31, 2019, our owned and leased fleet (excluding rentals) is comprised of the following categories:

Category	Capacity Range	Horsepower Range	Number Owned	Number Leased
Mining trucks	40 to 400 tons	476 ‑ 2,700	176	91
Articulating trucks	30 to 40 tons	305 ‑ 406	3	23
Loaders	1.5 to 16 cubic yards	110 ‑ 690	46	5
Shovels	18‑80 cubic yards	1,300 ‑ 3,760	5	2
Excavators	1 to 29 cubic yards	90 ‑ 1,944	37	60
Dozers	20,741 lbs to 230,100 lbs	96 - 850	77	32
Graders	14 to 24 feet	150 ‑ 500	24	6
Packers	14,175 to 68,796 lbs	216 ‑ 315	2	2
Other heavy equipment			20	1
Total			390	222

Competitive Conditions

Much of our business is secured through the formal competitive bidding process.Our competitive environment and customer behavior has 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. The lack of pipeline capacity has led to the curtailment of customer investment, resulting in some competitors getting out of the space, as well as stiffer competition for oil sands project tenders with the remaining competitors.

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.

We believe that 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 in the Canadian oil sands. We and our predecessors 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 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. We believe 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. We also believe that this 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;

• 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 mining equipment hydraulic cylinders for our Caterpillar mining equipment and an alternative supplier of powertrain components for select Caterpillar equipment; and

Annual Information Form 5 North American Construction Group Ltd.

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

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 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.

Employees and Labour Relations

As at December 31, 2019, we had 186 salaried employees (2018 - 160 salaried employees) and approximately 1,738 hourly employees (2018 - 1,570 hourly employees) in our western Canadian operations (excluding employees employed by the Nuna Group). Of the hourly employees, approximately 84% of the employees are union members and work under collective bargaining agreements (December 31, 2018 - 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 7.0% to 10.0% 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 2021.

Other collective agreements include the provincial collective agreement between the Operating Engineers and the Alberta ‘Roadbuilders and Heavy Construction’ Association ("ARBHCA"), which has expired. The parties have agreed to extend the term of the current agreement while negotiations continue and have also agreed to a project-specific term, with a no-strike/no-lockout clause for long-term work. A collective agreement, specific to work performed in our Acheson facilities between the Operating Engineers and North American Maintenance Ltd. is in place until 2023.

We also have a collective agreement in place with the Construction and Allied Workers Union ("CLAC"), Local 68 for work carried out at the Highland Valley Copper Mine project located near Logan Lake, British Columbia, which expires in April 2020.

Our relationship with all our employees, both union and non-union, is strong. We have not experienced a strike or lockout, nor do we expect to.

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 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.

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.

Debt Ratings

On December 20, 2019, S&P Global Ratings ("S&P") maintained our company outlook of "positive" while affirming our "B" long-term corporate credit rating. S&P further confirmed that the financial risk profile could be raised to a "B+" if operations are in line with the enhanced estimates of operating and credit metric forecasts for 2020.

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.

Jay Thornton is a director of Obsidian Energy Ltd., which was previously named Penn West Petroleum Ltd. (“Penn West”). On August 5, 2014, the Alberta Securities Commission and Ontario Securities Commission both granted Penn West, upon Penn West’s application, management cease trade orders in relation to a review of Penn West’s accounting practices and restatement of its financial statements. Those cease trade orders are no longer in effect as of September 23, 2014.

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.

H. 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 belief that the combination of our significant size and extensive experience will allow us to be successful in bidding and performing large-scale earthworks infrastructure and resource development work in both Canada and the United States.

2. Our anticipation that we will not experience a tire shortage due to our inventory levels and availability from manufacturers.

3. Our expectation that we will not experience a strike or lockout.

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

Annual Information Form 14 North American Construction Group Ltd.

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.

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.

• Cashflow, Liquidity and Debt. As of December 31, 2019, we had $412.1 million of total debt, representing long-term debt and finance leases. While we have achieved a significant improvement in the flexibility to borrow against our borrowing capacity, 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;

• 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.

• 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.

• 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

Annual Information Form 15 North American Construction Group Ltd.

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 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.

• 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 95% and 89% of our total revenue for the years ended December 31, 2019 and 2018, 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. Our long-term contracts typically allow our customers to unilaterally reduce or eliminate the work that we are to perform under the contract. Our contracts also generally allow the customer to terminate the contract without cause and, in many cases, 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.

• Capital Investment by Our Customers. Most of our customers are Canadian energy companies and our success is therefore highly reliant on a robust Canadian energy industry and continued capital investment. Due to the amount of capital investment required to build an oil sands project, or construct significant capital expansion to an existing project, investment decisions by oil sands operators are based upon long-term views of the economic viability of the project. Economic viability is dependent upon the anticipated revenues the capital project will produce, the anticipated amount of capital investment required and the anticipated fixed cost of operating the project. The most important consideration is the customer's view of the long-term price of oil, which is influenced by many factors, including the condition of developed and developing economies and the resulting demand for oil and gas, the level of supply of oil and gas, the actions of the Organization of Petroleum Exporting Countries ("OPEC"), government regulation, political conditions in oil producing nations, including those in the Middle East, war or the threat of war in oil producing regions and the availability of fuel from alternate sources. If our customers believe the long-term outlook for the price of oil is not favourable, or believe oil sands projects are not viable for any other reason, they may delay, reduce or cancel plans to construct new oil sands capital project or capital expansions to existing projects. Other factors may affect our customer’s willingness to undertake capital expenditures, which include but are not limited to, general market volatility, global economic conditions affecting worldwide capital markets, technological advancements making alternate sources of energy more viable, challenges in obtaining environmental permits, shortage of skilled workers, cost overruns on other existing projects, lack of sufficient infrastructure to support growth, introduction of onerous “green” legislation, negative perception of the Alberta oil sands and a shortage of sufficient pipeline and railway capacity to transport production to major markets.

• 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.

• Labour Disputes. Substantially all 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 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.

• 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

Annual Information Form 16 North American Construction Group Ltd.

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.

• Lump-sum and Unit-price Contracts. Approximately 52%, 62% and 65% of our revenue for the years ended December 31, 2019, 2018 and 2017, respectively, was derived from lump-sum and unit-price contracts. Lump-sum and 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;

• unfavourable 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 lump-sum 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 lump-sum and 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.

• 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 $4.9 million 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 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

Annual Information Form 17 North American Construction Group Ltd.

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 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.

• Leasing Cost and Availability. A portion of our equipment fleet is currently leased from third parties. Other future projects may require us to lease additional equipment. If equipment lessors are unable or unwilling to provide us with reasonable lease terms within our expectations, it will significantly increase the cost of leasing equipment or may result in more restrictive lease terms.

• 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 its business and is subject to information technology and system risks, including hardware failure, cyber-attack, security breach and destruction or interruption of the Company’s 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 its 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 cyber security breach that has resulted in a material impact on its business or operations; however, there is a possibility that the measures we take to protect its information technology systems may not be effective in protecting against a 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.

• 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.

• Climate Change Laws and Regulations. Climate change continues to attract considerable public and regulatory attention, with greenhouse gas emission regulations becoming more commonplace and stringent. 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 the Company operates impose carbon taxes on significant emitters and there is a possibility of similar taxation in other jurisdictions in the future. Our cost of business may rise and 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. Other government restrictions on certain market sectors, such as oil sands, could also adversely impact current or potential clients resulting in a reduction of available work.
