News Release
North American Construction Group Ltd. Announces Results
for the Third Quarter Ended September 30, 2021
ACHESON, Alberta, October 27, 2021 - North American Construction Group Ltd. (“NACG”) (TSX:NOA/NYSE:NOA) today announced results for the third quarter ended September 30, 2021. Unless otherwise indicated, financial figures are expressed in Canadian dollars and comparisons are to the prior period ended September 30, 2020.
Third Quarter 2021 Highlights:
•Adjusted EBITDA of $47.5 million was 28% higher than prior year adjusted EBITDA of $37.1 million reflecting improved operating conditions from the prior year, consistently increasing demand for our heavy equipment fleet and a step change in scope being completed by the Nuna Group of Companies ("Nuna").
•Gross profit of $21.7 million or 13.1% continued to reflect the macro impacts of COVID-19 but was also impacted by equipment maintenance completed in anticipation of a busy winter season. The operational impacts of safety protocols and workforce availability are estimated to have impacted gross profit by approximately $3.0 million net of government assistance and wage subsidy programs.
•Free cash flow ("FCF") in the quarter of $10.0 million was generated from strong adjusted EBITDA less sustaining capital expenditures but was noticeably impacted by deferred timing of cash receipts from our various joint ventures which we expect to receive in the normal course.
•Senior debt was $274.0 million as at September 30, 2021, a decrease of $79.2 million from the December 31, 2020 balance as proceeds from newly issued debentures were used to reduce senior debt.
•On July 21, 2021, we announced a contract amendment to a multiple use agreement between the Mikisew North American Limited Partnership and a major oil sands producer. We anticipate our share to be approximately $175 million in additional revenue over the remainder of the agreement.
•On September 14, 2021, we announced a contract award to Mikisew North American Limited Partnership ("MNALP") by a major oil sands producer. The contract extends the existing master service agreement between us and the producer to December 2023 but transitions to MNALP as the contractor. We anticipate the contract to generate approximately $275 million in revenue over the term of the agreement.
•On September 29, 2021, we announced amendment and extension of our senior secured credit facility which extended the facility date by one year with a new maturity date of October 8, 2024. In addition to the extension of existing favourable terms, amendments have also been incorporated that provide us a greater flexibility in operating through joint ventures, including joint ventures related to larger contracts under public-private-partnership financing models.
NACG President and CEO, Joseph Lambert, commented: “Thankfully, our Q3 financial performance was much more stable than Q2 and the consistency in operating conditions allowed for predictable results. Our operating margins continue to be impacted by the necessary safety protocols in place at the various mine sites, but the impacts were far less severe than last quarter. The financial close of the Fargo-Moorhead project and the seamless integration of DGI Trading are strong milestones in our strategy to diversify our business. That said, the resumption of work at Fort Hills and the contract amendments recently secured with oil sands producers illustrates the strength of this region and we remain committed to serving these customers.
Without taking our eye off of this critical Q4, we look to 2022 and have provided our range of outcomes based on the projects we currently have in place. I am, of course, keenly aware of the exciting momentum we feel internally here at NACG but it really shows up quantitatively when we look at the estimates for next year. We see the goals ahead of us and are focused on execution."

Declaration of Quarterly Dividend
On October 26th, 2021, the NACG Board of Directors declared a regular quarterly dividend (the “Dividend”) of four Canadian cents ($0.04) per common share, payable to common shareholders of record at the close of business on November 30, 2021. The Dividend will be paid on January 7, 2022 and is an eligible dividend for Canadian income tax purposes.
Financial Results for the Three Months Ended September 30, 2021
Revenue was $166.0 million, up from $93.6 million in the same period last year. revenue has increased as a result of the continuation of previously delayed work, as well as an increased demand for our services on new projects. In the quarter, we re-mobilized equipment to the Fort Hills mine and began completing earthwork, overburden, and heavy civil construction activities, which is expected to continue for the remainder of the year. The suspension of work at the Fort Hills mine caused a reduction in year-over-year revenue which has returned to a more normalized level in Q3. The demand for mine support work and equipment rental support at the Kearl mine remained strong for the quarter which was complemented by the completion of a haul truck rebuild and a dozer repair through our external maintenance program. Outside of our operations in the Fort McMurray region, revenue was positively impacted by the acquisition of Australian component supplier DGI Trading PTY Limited. Our share of Nuna's revenue, which is consolidated in equity earnings, was $45.8 million in Q3 2021.
Gross profit margin of 13.1% was down from the prior year driven manpower shortages from isolation and vaccination requirements which increased overtime and other operating costs. Additionally, the margin was impacted by increased equipment maintenance activities as we performed services to ensure our fleet is operating at full capacity for the large demand of work ahead of us. Partially offsetting these decreases were the operating

performance related to the newly awarded scopes at the Fort Hills mine and the profit generated from our acquisition of DGI trading.
Direct general and administrative expenses (excluding stock-based compensation benefit) were $7.1 million, equivalent to 4.3% of revenue, higher than Q3 2020 of $3.7 million and 4.0% driven by lower wage subsidies.
Cash related interest expense for the quarter of $4.5 million represents an average interest rate of 4.3% as we continue to benefit from both reductions in posted rates as well as the competitive rates in equipment financing.
Free cash flow of $10.0 million in the quarter was positively impacted by higher profitability and changes related to working capital balances due to the acquisition of DGI. In addition, positive cash flow of $23.8 million was generated by adjusted EBITDA of $47.5 million detailed above offset by sustaining capital additions of $19.8 million and cash interest paid of $4.0 million. Sustaining maintenance expenditures remained consistent with the expectations of the 2021 capital maintenance plan reflecting necessary maintenance in anticipation of our busy winter season.
BUSINESS UPDATES
Focus & Priorities for the Remainder of 2021
•Safety - focus on people and relationships as we emerge from the pandemic, maintain an uncompromising commitment to health and safety while elevating the standard of excellence in the field.
•Sustainability - commitment to the continued development of sustainability targets and consistent measurement of progress to those targets.
•Diversification - continue to pursue further diversification of customer, resource and geography through strategic partnerships, industry expertise and/or investment in Indigenous joint ventures.
•Execution - enhance our record of operational excellence with respect to fleet maintenance, availability and utilization through leverage of our reliability programs, technical improvements and management systems.
Contract Award and Extension
On September 14, 2021, we announced a contract award to Mikisew North American Limited Partnership ("MNALP") by a major oil sands producer. The contract effectively extends the existing master service agreement between NACG and the producer to December 2023 but transitions to MNALP as the contractor. NACG anticipates the contract to generate approximately $275 million in revenue for NACG over the term of the agreement.
Increase in Committed Scope from Contract Amendment
On July 21, 2021, the Company announced a contract amendment to a multiple use agreement between the Mikisew North American Limited Partnership and a major oil sands producer. The agreement has an expiration date of December 2023 and the Company anticipates its share to be approximately $175 million in additional revenue over the remainder of the agreement.
Issuance of $75 million of Convertible Debentures
On June 1, 2021 we closed an offering of 5.50% convertible unsecured debentures for gross proceeds of $65 million. On June 4, 2021, underwriters exercised their over-allotment option, in full, to purchase an additional $9.8 million for aggregate gross proceeds of $74.8 million. The majority of proceeds have been deployed to decrease senior debt through reducing the balance on our credit facility.
Total liquidity of $189.7 million as at September 30, 2021 represents an increase of $42.1 million over the December 31, 2020 balance. Liquidity is primarily provided by the terms of our $325.0 million credit facility which allows for funds availability based on a trailing twelve-month EBITDA and is scheduled to expire in October 2023.
Normal Course Issuer Bid ("NCIB")
On April 9, 2021, we commenced a normal course issuer bid ("NCIB") under which a maximum number of 2,000,000 common shares were authorized to be purchased. During the nine months ended September 30, 2021, we purchased and subsequently cancelled 37,000 shares under this NCIB, which resulted in a decrease of common shares of $0.3 million and a decrease to additional paid-in capital of $0.2 million. To comply with applicable securities laws, no more than 1,497,476 voting common shares will be purchased on the New York Stock Exchange ("NYSE") or alternative trading systems. This NCIB will be terminated no later than April 8, 2022.

Basis of Presentation
We have prepared our consolidated financial statements in conformity with accounting principles generally accepted in the United States ("US GAAP"). Unless otherwise specified, all dollar amounts discussed are in Canadian dollars. Please see the Management’s Discussion and Analysis (“MD&A”) for the quarter ended September 30, 2021 for further detail on the matters discussed in this release. In addition to the MD&A, please reference the dedicated Q3 2021 Results Presentation for more information on our results and projections which can be found on our website under Investors - Presentations.
Change in significant accounting policy - Basis of presentation
Prior to July 1, 2021, we elected to apply the provision available to entities operating within the construction industry to apply proportionate consolidation to unincorporated entities that would otherwise be accounted for using the equity method. During the three months ended September 30, 2021, we elected to change this policy to account for these unincorporated entities using the equity method, resulting in a change to the consolidation method for Dene North Site Services and Mikisew North American Limited Partnership. This change allows for consistency in the presentation of our investments in affiliates and joint ventures. We have accounted for the change retrospectively according to the requirements of US GAAP Accounting Standards Codification ("ASC") 250 by restating the comparative periods. For full disclosure, refer to note 14 in our Financial Statements for September 30, 2021.

Non-GAAP Financial Measures
This press release presents certain non-GAAP financial measures because management believes that they may be useful to investors in analyzing our business performance, leverage and liquidity. The non-GAAP financial measures we present include "adjusted net earnings", "adjusted EBIT", "equity investment EBIT", "adjusted EBITDA", "adjusted EBITDA margin", "total combined revenue", "equity investment depreciation and amortization", "adjusted EPS", "margin", "net debt", "senior debt", "sustaining capital", "growth capital", "cash provided by operating activities prior to change in working capital" and "free cash flow". A non-GAAP financial measure is defined by relevant regulatory authorities as a numerical measure of an issuer's historical or future financial performance, financial position or cash flow that is not specified, defined or determined under the issuer’s GAAP and that is not presented in an issuer’s financial statements. These non-GAAP measures do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other companies. They should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Each non-GAAP financial measure used in this press release is defined and reconciled to its most directly comparable GAAP measure in the “Non-GAAP Financial Measures” section of our Management’s Discussion and Analysis filed concurrently with this press release.
A reconciliation of total reported revenue to total combined revenue is as follows:
