SOLICITATION OF PROXIES

This management information circular (the “Circular”) and accompanying form of proxy (the “Proxy”) are furnished in connection with the solicitation of proxies by or on behalf of management of North American Construction Group Ltd. (the “Corporation”, “NACG”, “our” or “we”) for use at the annual and special meeting (the “Meeting”) of holders of voting common shares of the Corporation (the “NACG Shareholders”) to be held at the head office of the Corporation at 27287 – 100 Avenue, Acheson, Alberta on the 20th day of May, 2026, at 3:00 p.m. (Mountain Time), and at any adjournments thereof, for the purposes set forth in the accompanying notice of meeting dated April 8, 2026 (the “Notice of Meeting”).

It is expected that the solicitation will be primarily by mail. Proxies may also be solicited personally by officers of the Corporation at nominal cost. The cost of this solicitation will be borne by the Corporation. The Corporation may pay the reasonable costs incurred by persons who are the registered but not beneficial owners of voting shares of the Corporation (such as brokers, dealers, other registrants under applicable securities laws, nominees and/or custodians) in sending or delivering copies of this Circular, the Notice of Meeting and Proxy to the beneficial owners of such shares. The Corporation will provide, without cost to such persons, upon request to the Secretary of the Corporation, additional copies of the foregoing documents required for this purpose.

For the purposes of the Meeting, the Corporation is not: (a) relying on the “notice and access” rules to allow it to make certain proxy-related materials available on the internet rather than mailing such materials directly to registered shareholders and indirectly to non-registered shareholders; or (b) mailing proxy-related materials directly to non-registered shareholders who have not waived the right to receive them. The Corporation intends to pay for “proximate intermediaries” (as defined in National Instrument 54-101 – Communication with Beneficial Owners of Securities of a Reporting Issuer) to send proxy-related materials and Form 54-101F7 – Request for Voting Instructions Made by Intermediary to non-registered shareholders who have waived the right to receive them.

The Notice of Meeting, Proxy and this Circular will be mailed to NACG Shareholders commencing on or about April 23, 2026. In this Circular, except where otherwise indicated, all dollar amounts are expressed in Canadian currency.

No person has been authorized by the Corporation to give any information or make any representations in connection with the matters contained herein other than those contained in this Circular and, if given or made, any such information or representation must not be relied upon as having been authorized by the Corporation.

This Circular does not constitute an offer or a solicitation to any person in any jurisdiction in which such offer or solicitation is unlawful.

RECORD DATE

The record date (the “Record Date”) for determining which NACG Shareholders shall be entitled to receive notice of and to vote at the Meeting is April 13, 2026. Only NACG Shareholders of record as of the Record Date are entitled to receive notice of and to vote at the Meeting, unless after the Record Date such shareholder of record transfers its shares and the transferee (the “Transferee”), upon establishing that the Transferee owns such shares, requests in writing at least 10 days prior to the Meeting or any adjournments thereof that the Transferee may have his, her or its name included on the list of NACG Shareholders entitled to vote at the Meeting, in which case the Transferee is entitled to vote such shares at the Meeting. Such written request by the Transferee shall be filed with Computershare Investor Services Inc., 14th Floor, 320 Bay Street, Toronto, Ontario, M5H 4A6, together with a copy to the Secretary of the Corporation at 27287 – 100 Avenue, Acheson, Alberta, T7X 6H8.

Under normal conditions, confidentiality of voting is maintained by virtue of the fact that the Corporation’s transfer agent tabulates proxies and votes. However, such confidentiality may be lost as to any proxy or ballot if a question arises as to its validity or revocation or any other like matter. Loss of confidentiality may also occur if the Board of Directors decides that disclosure is in the interest of the Corporation or its shareholders.

APPOINTMENT OF PROXYHOLDERS

The persons named in the accompanying Proxy as proxyholders are representatives of management of NACG. Every NACG Shareholder has the right to appoint a person or company to represent them at the Meeting other than the persons named in the accompanying Proxy. A NACG Shareholder desiring to appoint some other person (who need not be a shareholder of NACG) to represent him, her or it at the Meeting, may do so either by striking out the printed names and inserting the desired person’s name in the blank space provided in the

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

Proxy or by completing another proper proxy and, in either case, delivering the completed proxy to our transfer agent Computershare Investor Services Inc., (i) by mail using the enclosed return envelope or one addressed to Computershare Investor Services Inc., Proxy Department, 14th Floor, 320 Bay Street, Toronto, Ontario, M5H 4A6, or (ii) by hand delivery to Computershare Investor Services Inc., 14th Floor, 320 Bay Street, Toronto, Ontario, M5H 4A6. Alternatively, you may vote electronically by telephone (1-866-732-8683) or internet (www.investorvote.com) by following the instructions on the enclosed form of proxy. Your proxy or voting instructions must be received in each case no later than 3:00 p.m. (Mountain Time), on May 15, 2026 and if the Meeting is adjourned, no later than 48 hours (excluding Saturdays and holidays) prior to the commencement of any adjournment thereof. A Proxy must be signed by a NACG Shareholder or its attorney duly authorized in writing or, if a NACG Shareholder is a corporation, by a duly authorized officer, attorney or other authorized signatory of the NACG Shareholder. If a proxy is given by joint shareholders, it must be executed by all such joint shareholders.

VOTING OF PROXIES

If a Proxy is completed, signed and delivered to the Corporation in the manner specified above, the persons named as proxyholders therein shall vote or withhold from voting the shares in respect of which they are appointed as proxyholders at the Meeting, in accordance with the instructions of the NACG Shareholder appointing them, on any show of hands or any ballot that may be called for and, if the NACG Shareholder specifies a choice with respect to any matter to be acted upon at the Meeting, the persons appointed as proxyholders shall vote in accordance with the specification so made. In the absence of such specification, or if the specification is not certain, the shares represented by such Proxy will be voted in favour of the matters to be acted upon as specified in the Notice of Meeting.

A Proxy confers discretionary authority upon the persons named therein with respect to amendments or variations to matters identified in the Notice of Meeting and all other matters which may properly come before the Meeting or any adjournments thereof. As of the date of this Circular, the Board of Directors of the Corporation knows of no such amendments, variations or other matters to come before the Meeting, other than matters referred to in the Notice of Meeting. However, if amendments, variations or other matters should properly arise before the Meeting, the Proxy will be voted on such amendments, variations and other matters in accordance with the best judgment of the person or persons voting such Proxy.

REVOCABILITY OF PROXY

Any NACG Shareholder returning an enclosed Proxy may revoke the same at any time insofar as it has not been exercised. In addition to revocation in any other manner permitted by law, a Proxy may be revoked by instrument in writing executed by the NACG Shareholder or by his, her or its attorney authorized in writing or, if the NACG Shareholder is a corporation, by an officer or attorney thereof duly authorized, and deposited at the registered office of the Corporation to the attention of the Secretary of the Corporation, at any time up to and including the last business day preceding the day of the Meeting, or any adjournment thereof, or with the chairperson of the Meeting, prior to the commencement of the Meeting. A NACG Shareholder attending the Meeting has the right to vote in person and, if he, she or it does so, his, her or its proxy is nullified with respect to the matters such person votes upon and any subsequent matters thereafter to be voted upon at the Meeting or any adjournment thereof.

ADVICE TO BENEFICIAL HOLDERS OF COMMON SHARES

The information set forth in this section is of significant importance to many NACG Shareholders, as a substantial number of NACG Shareholders do not hold voting common shares of the Corporation (“NACG Common Shares”) in their own name, and thus are considered non-registered shareholders. NACG Shareholders who do not hold their NACG Common Shares in their own name (“Beneficial Shareholders”) should note that only Proxies deposited by NACG Shareholders whose names appear on the records of the Corporation as the registered holders of NACG Common Shares can be recognized and acted upon at the Meeting. If NACG Common Shares are listed in an account statement provided to a NACG Shareholder by a broker, then, in almost all cases, those NACG Common Shares will not be registered in the NACG Shareholder’s name on the records of the Corporation. Such NACG Common Shares will more likely be registered under the name of the NACG Shareholder’s broker or an agent of that broker or another similar entity (called an “Intermediary”). NACG Common Shares held by an Intermediary can only be voted by the Intermediary (for, withheld or against resolutions) upon the instructions of the Beneficial Shareholder. Without specific instructions, Intermediaries are prohibited from voting NACG Common Shares.

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

Beneficial Shareholders should ensure that instructions respecting the voting of their NACG Common Shares are communicated in a timely manner and in accordance with the instructions provided by their Intermediary. Applicable regulatory rules require Intermediaries to seek voting instructions from Beneficial Shareholders in advance of shareholders’ meetings. Every Intermediary has its own mailing procedures and provides its own return instructions to clients, which should be carefully followed by Beneficial Shareholders in order to ensure that their NACG Common Shares are voted at the Meeting.

Although a Beneficial Shareholder may not be recognized directly at the Meeting for the purposes of voting NACG Common Shares registered in the name of their Intermediary, a Beneficial Shareholder may attend at the Meeting as proxyholder for the Intermediary and vote the NACG Common Shares in that capacity. Beneficial Shareholders who wish to attend the Meeting and indirectly vote their NACG Common Shares as a proxyholder, should enter their own names in the blank space on the form of proxy provided to them by their Intermediary and timely return the same to their Intermediary in accordance with the instructions provided by their Intermediary, well in advance of the Meeting.

NOTICE TO UNITED STATES SHAREHOLDERS

The solicitation of proxies by the Corporation is not subject to the requirements of Section 14(a) of the United States Securities Exchange Act of 1934, as amended (the “US Exchange Act”), by virtue of an exemption applicable to proxy solicitations by “foreign private issuers” as defined in Rule 3b-4 under the US Exchange Act. Accordingly, this Circular has been prepared in accordance with the applicable disclosure requirements in Canada. Residents of the United States should be aware that such requirements may be different than those applicable to proxy statements subject to Section 14(a) of the US Exchange Act.

VOTING SHARES AND PRINCIPAL HOLDERS THEREOF

The Corporation’s authorized capital consists of an unlimited number of NACG Common Shares and an unlimited number of non-voting common shares. None of the Corporation’s shares have par value. As at March 31, 2026, there were a total of 28,414,864 NACG Common Shares outstanding and no non-voting common shares outstanding. Each NACG Common Share entitles the holder thereof to one vote in respect of each of the matters to be voted upon at the Meeting. To the knowledge of the Corporation’s directors and executive officers, as of March 31, 2026, no individuals or entities beneficially own, control or direct, directly or indirectly, securities carrying more than 10.0% of the voting rights attached to the NACG Common Shares.

QUORUM

A quorum for the transaction of business at the Meeting shall consist of at least two persons holding or representing by proxy not less than twenty percent (20%) of the outstanding shares of the Corporation entitled to vote at the meeting.

If a quorum is not present at the opening of the Meeting, the NACG Shareholders present may adjourn the meeting to a fixed time and place but may not transact any other business. If a meeting of shareholders is adjourned by one or more adjournments for an aggregate of less than 30 days it is not necessary to give notice of the adjourned meeting other than by announcement at the time of an adjournment. If a meeting of NACG Shareholders is adjourned by one or more adjournments for an aggregate of more than 29 days and not more than 90 days, notice of the adjourned meeting shall be given as for an original meeting but the management of the Corporation shall not be required to send a form of proxy in the form prescribed by applicable law to each NACG Shareholder who is entitled to receive notice of the meeting. Those shareholders present at any duly adjourned meeting shall constitute a quorum.

The Corporation’s list of NACG Shareholders as of the Record Date has been used to deliver to NACG Shareholders the Notice of Meeting and this Circular as well as to determine the NACG Shareholders who are eligible to vote.

PRESENTATION OF FINANCIAL STATEMENTS

The audited consolidated financial statements of the Corporation for the fiscal year ended December 31, 2025, together with the auditor’s report thereon, copies of which are contained in the Corporation’s annual report, will be presented to the NACG Shareholders at the Meeting. Receipt at the Meeting of the auditor’s report and the Corporation’s financial statements for its last completed fiscal period will not constitute approval or disapproval of any matters referred to therein.

John Pollesel is a director of Electra Battery Minerals Corporation, which was formerly known as 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.

Recommendation of the Board of Directors

The Board of Directors recommends a vote “FOR” the election of each of the above nominees to serve as a director of the Corporation.

Unless a NACG Shareholder otherwise directs, or directs that his or her NACG Common Shares are to be voted “AGAINST” the election of any particular nominee specified above, the persons named in the enclosed form of Proxy intend to vote “FOR” the election of each of the nominees specified above, such directors to hold office until the next annual meeting or until his or her successor is appointed.

2.	Advisory Vote on Executive Compensation

The Corporation’s compensation policies and procedures are based on the principle of pay for performance. The Board of Directors believes they align the interests of the Corporation’s executive team with the long-term interests of NACG Shareholders. The Board also believes that NACG Shareholders should have the opportunity to fully understand the objectives, philosophy and principles used in its approach to executive compensation decisions and to have an advisory vote on the Board’s approach to executive compensation. This non-binding advisory vote, commonly known as “Say-on-Pay”, gives each NACG Shareholder an opportunity to either endorse or not endorse the Corporation’s approach to its executive pay program and policies through the following resolution:

“Resolved, on an advisory basis and not to diminish the role and responsibilities of the board of directors, that the shareholders of North American Construction Group Ltd. (the “Corporation”) accept the approach to executive compensation disclosed in the management information circular delivered in advance of the 2026 annual and special meeting of shareholders of the Corporation.”

Approval of the above resolution will require an affirmative vote of a majority of the votes cast at the Meeting.

The purpose of the Say-on-Pay advisory vote is to provide appropriate director accountability to the NACG Shareholders for the Board’s compensation decisions by giving NACG Shareholders a formal opportunity to provide their views on the disclosed objectives of the executive compensation plans, and on the plans themselves, for the past, current and future fiscal years. While NACG Shareholders will provide their collective advisory vote, the directors of the Corporation remain fully responsible for their compensation decisions and are not relieved of these responsibilities by a positive advisory vote by NACG Shareholders.

As this is an advisory vote, the results will not be binding on the Board. However, the Board will take the results of the vote into account, as appropriate, when considering future compensation policies, procedures and decisions and in determining whether there is a need to significantly increase their engagement with NACG Shareholders on compensation and related matters. The Corporation will disclose the results of the Say-on-Pay vote as a part of its report on voting results for the Meeting.

In the event that a significant number of Shareholders oppose the resolution, the Chair of the Board and the Chair of the Human Resources and Compensation Committee will oversee a consultation process with NACG Shareholders, particularly those who are known to have voted against it, in order to better understand their concerns. The Human Resources and Compensation Committee will review the Corporation’s approach to compensation in the context of those concerns. Shareholders who have voted against the resolution will be encouraged to contact the Chair of the Board to discuss their specific concerns. Such discussion may be initiated by a Shareholder by sending an e-mail requesting the same to the Corporation’s Investor Relations department at [email protected].

Following the review by the Human Resources and Compensation Committee, the Corporation will disclose to Shareholders a summary of the significant comments relating to compensation received from Shareholders in the process, a description of the process undertaken and a description of any resulting changes to executive compensation or why no changes will be made. The Corporation will provide this disclosure within six months of the Say-on-Pay vote, and no later than in the management information circular for its next annual meeting.

Management Information Circular

The Board recognizes that Say-on-Pay is an evolving area and will review this policy annually to ensure that it is effective in achieving its objectives.

Recommendation of the Board of Directors

The Board of Directors recommends a vote “FOR” the Corporation’s approach to executive compensation as described in the “Compensation Discussion and Analysis” portion of this Circular.

Unless a NACG Shareholder otherwise directs, or directs that his or her NACG Common Shares are to be withheld from voting in connection with the above resolution with respect to approval of the Corporations’ approach to executive compensation, the persons named in the enclosed form of Proxy intend to vote for the above resolution with respect to approval of the Corporations’ approach to executive compensation.

3.	Ratification of Advance Notice By-Law

On March 19, 2026, the Board approved By-Law No. 3 of the Corporation (the “Advance Notice By-law”), with effect as of such date, the Board having determined that approval of such by-law was in accordance with corporate governance best practices and in the best interests of the Shareholders. The purpose of the Advance Notice By-law is to provide Shareholders, directors, and management of the Corporation with guidance on the nomination of directors. The Advance Notice By-law includes, among other things, a provision that requires advance notice be given to the Corporation in circumstances where nominations of persons for election to the Board are made by Shareholders of the Corporation. Additionally, the Advance Notice By-law sets a deadline by which Shareholders must submit director nominations to the Corporation prior to any annual general or special meeting of Shareholders and sets forth the information that a Shareholder must include in the notice to the Corporation for the notice to be in proper written form for a nominee to be eligible for election.

In the case of an annual general meeting of shareholders, notice to the Corporation must be made not less than thirty (30) days prior to the date of the annual general meeting. However, in the event that the annual general meeting is to be held on a date that is less than fifty (50) days after the date on which the first public announcement of the date of the annual general meeting was made, notice may be made not later than the close of business on the tenth (10th) day following such public announcement. In the case of a special meeting of shareholders (which is not also an annual general meeting) notice to the Corporation must be made not later than the close of business on the fifteenth (15th) day following the day on which the first public announcement of the date of the special meeting was made. Notwithstanding the foregoing, the Board may, in its discretion, waive any requirement set out in the Advance Notice By-law. Pursuant to the provisions of the CBCA, the Advance Notice By-law was effective as of March 19, 2026, and will be placed before Shareholders for approval, confirmation and ratification at the Meeting. At the Meeting, Shareholders will be asked to consider and, if deemed advisable, approve and confirm, with or without variation, the following ordinary resolution ratifying, approving and confirming the Advance Notice By-law:

“Resolved that:

1. By-Law No. 3 of the Corporation dated March 19, 2026 (the “Advance Notice By-law”), in the form set out in Schedule B to the management information circular of the Corporation dated April 8, 2026, be and is hereby ratified, approved and confirmed;

2. The board of directors of the Corporation is authorized on behalf of the Corporation to make any amendments to the Advance Notice By-law as may be required by applicable regulatory authorities, without further approval of the shareholders of the Corporation, in order to ensure adoption of the Advance Notice By-law;

3. Any one director or officer of the Corporation be and is hereby authorized and directed to do all things and to execute and deliver all documents and instruments as may be necessary or desirable to carry out the terms of this resolution.”

In order to be passed, the resolution respecting the Advance Notice By-law must be approved by a simple majority of votes cast by Shareholders who vote in person or by proxy at the Meeting in respect of the resolution. The Advance Notice By-law provides that if it is not approved by an ordinary resolution of the Shareholders passed at the Meeting, then it shall terminate and be void and of no further force and effect.

The above summary is qualified in its entirety by the full text of the Advance Notice By-law attached to this Circular as Schedule B. The full text of the Advance Notice By-law is also available under the Corporation’s profile on SEDAR+ at www.sedarplus.com.

LETTER FROM HUMAN RESOURCES & COMPENSATION COMMITTEE CHAIR

Dear Fellow Shareholders,

On behalf of the Human Resources and Compensation Committee, I am pleased to share an overview of our approach to executive compensation, which is designed to support NACG’s strategy and align management’s interests with those of shareholders.

Pay Philosophy

NACG’s executive compensation philosophy is guided by the following fundamental principles: alignment with shareholder interests and pay for performance, transparency disclosure, and market-competitive compensation. A significant portion of executive compensation is variable and tied to corporate performance, safety, and long-term shareholder value creation. The Committee regularly reviews NACG’s compensation framework and market positioning, with the support of independent advisors, to help ensure the program remains appropriate for the Corporation’s evolving scale and strategy.

2025 Performance Context & Leadership Changes

In 2025, NACG continued to evolve as a larger and more diversified business, with the Australian platform becoming an increasingly important part of the Corporation’s scale, strategy, and leadership profile. The year also reflected the continued evolution of the business following the MacKellar acquisition and the announced acquisition of Iron Mine Contracting, further strengthening NACG’s position in Australia. The Corporation delivered record combined revenue and strong free cash flow, while earnings were affected by the Fargo-Moorhead cost update despite NACG’s earthworks portion of the project which performed as expected; furthermore, weather-related impacts in Queensland. This broader context shaped the Committee’s work throughout the year, including how we assessed executive roles, market competitiveness, and compensation outcomes.

The Committee’s work in 2025 and early 2026 also took place alongside changes in NACG’s executive leadership team. In January 2026, Joe Lambert resigned as President and Chief Executive Officer, and Barry Palmer assumed the role. The named executive officer group also evolved in 2025 to reflect the increasing scale and importance of NACG’s Australian operations following the MacKellar acquisition.

2025 Compensation Outcomes

NACG’s 2025 short-term incentive plan (“STIP”) measured performance against Bonus EBIT, Bonus EBITDA, Total Recordable Injury Rate (“TRIR”), and Serious Injury or Fatality Potential Rate (“SIFp”). Compared to the prior year, the 2025 scorecard was refined to replace the debt reduction metric with Bonus EBITDA, resulting in a financial component based entirely on earnings measures.

NACG achieved an overall STIP score of 24.2% of target, with the lower outcome driven by financial performance below target, while safety performance remained strong. In our view, this outcome demonstrates the integrity of NACG’s pay-for-performance framework.

NACG’s long-term incentive plan (“LTIP”) remains a key vehicle for aligning executives with long-term shareholder value creation. For 2025, LTIP awards continued to be delivered in the form of performance share units (“PSUs”) and restricted share units (“RSUs”), with PSU performance measured over a three-year period based on relative total shareholder return, Adjusted EBIT, free cash flow, and adjusted return on invested capital.

The Committee also approved a one-time special incentive for Barry Palmer in 2024 in his role as COO and Regional President of Australia. The award recognized the significance of his mandate in integrating NACG’s Australian operations and advancing leadership succession in the region. The award, with a maximum value of $1,000,000, was contingent on the achievement of three specific goals by the end of 2025, all of which the Committee determined had been fully achieved.

Governance and Shareholder Engagement

NACG continues to hold an annual advisory Say-on-Pay vote, and the Committee values shareholder feedback as an important part of maintaining a compensation framework that remains aligned with the Corporation’s strategy and shareholder interests. We remain committed to strong governance and ongoing review of our compensation programs to ensure they continue to support NACG’s long-term success.

Management Information Circular

North American Construction Group Ltd.

In closing, we appreciate your continued support of NACG and encourage you to read the Compensation Discussion and Analysis section of this Circular for further detail on our executive compensation decisions and outcomes for 2025.

Sincerely,

Thomas P. Stan

COMPENSATION DISCUSSION AND ANALYSIS

2025 Named Executive Officers

The below discussion of executive compensation focuses on the compensation of the following executive team members for the year ended December 31, 2025, who are our “named executive officers” or “NEOs” for purposes of this compensation disclosure:


Named Executive Officer				Position in 2025

Joseph C. Lambert^(a)				President and Chief Executive Officer

Jason W. Veenstra				Chief Financial Officer

Barry W. Palmer				Chief Operating Officer and Regional President for Australia

Andre S. Desbiens				Managing Director, MacKellar Group

Thomas S. Arndell				Vice President, Asset Management

^(a)Mr. Lambert no longer holds the role of President and Chief Executive Officer. Effective January 20, 2026, Mr. Palmer has assumed the President and Chief Executive Officer role.

Executive Compensation Philosophy

Our executive compensation philosophy is guided by five fundamental principles – alignment with shareholder interests, pay for performance, transparent disclosure, shareholder say on pay and market competitive compensation:


Alignment with Shareholder Interests				It is in the Corporation’s best interest to meet or exceed shareholder expectations and to ensure continued access to capital on favorable terms. Accordingly, the pay “at-risk” or variable pay plans (Short-Term Incentive Plan (“STIP”) and Long-Term Incentive Plan (“LTIP”)) were designed to align the interests of the Corporation’s executives with shareholder interests.
Pay for Performance				The Corporation believes that executive compensation should be strongly correlated to the financial and safety performance of the Corporation, and that the executives, as the key decision makers of the Corporation, should be held accountable for that performance. To that end, the Board has adopted the annual STIP, which rewards executives for the achievement of key financial, safety and other individual objectives in the more immediate term, as well as the LTIP, which rewards executives for overall financial success and value creation over the longer term.
Transparent Disclosure				The Corporation is committed to providing transparent disclosure of executive compensation. It is our intent to follow best practices, comply with all regulatory requirements and communicate our executive pay in plain language.
Shareholder Say on Pay				The Human Resources and Compensation Committee (“HRCC”) and the Board review and consider all shareholder feedback related to compensation matters and will continue existing practices regarding shareholder discussion and engagement. Our first shareholder “Say on Pay” vote was conducted in May 2020 and established the framework for conducting an annual non-binding advisory vote by shareholders on executive compensation.
Market Competitive Compensation				The Corporation has adopted a market-competitive executive total compensation package. It is the goal of the Corporation to attract and retain talented executives who are capable and motivated to execute the financial and business objectives of the Corporation. It is important to ensure executive compensation is competitive within the market where the Corporation competes for talent.

Components of 2025 Executive Compensation

The following table summarizes the various components of compensation that NEOs were eligible to receive for 2025:


Component	Description	Time Frame
Base Salary	Salaries are based on the executive’s level of responsibility, skills and experience and the current market value of the position. Base salary adjustments are considered annually.	Annual market reviews and adjustments
Short-Term Incentive Plan (“STIP”)	STIP compensation is linked to the Corporation’s achievement of financial and safety performance in the fiscal year as compared to targets set by the Board. While the CEO’s STIP is based entirely on the Corporation’s achievement of targets, STIP for the other NEO’s includes an element of individual achievement. The value of each STIP target payout to an NEO is a fixed percentage of that NEO’s annual base salary, which percentage varies by position.	Annual performance
	Payouts range from zero to a maximum of 1.5 times an NEO’s individual target annual bonus (2.0 times for the CEO), based on level of individual and corporate achievement.
Long-Term Incentive Plan (“LTIP”)	LTIP grants are made through two vehicles: (1) performance share units (PSUs) and (2) restricted share units (RSUs). Each LTIP grant is awarded 60% as PSUs and 40% as RSUs. The value of each LTIP grant to an NEO is a fixed percentage of that NEO’s annual base salary, which percentage varies by position.	Three-year performance cycle
	Awards are equity-settled by the transfer of shares purchased by an arm’s length trust established for this purpose.
Special Incentive for COO / Regional President for Australia	The HRCC approved a special one-time incentive in 2024 applicable only to Mr. Palmer, in his role as COO and Regional President of Australia, related to the integration of Australian operations and succession of leadership within that region. The incentive was paid based on three targets set for Mr. Palmer to be achieved in 2025 in relation to such integration and succession, all of which the HRCC subsequently determined had been met.	Paid as one-time incentive
Retirement Arrangements	The Corporation matches contributions of Canadian NEO’s to Registered Retirement Savings Plans (“RRSPs”) up to a maximum of 5% of base salary. If or when the NEO reaches their annual contribution limits, the remaining contributions for the calendar year are made to a non-registered savings plan (“Group Investment Account”). For Australian NEO’s, the Corporation adheres to Superannuation compliance.	Paid in conjunction with base salary
Benefit Plans	Executive benefit plans, paid for by the Corporation, provide extended health, dental, disability and insurance coverage.	Monthly premiums
Perquisites	Limited perquisites are provided such as a vehicle allowance, and reimbursement of fuel purchases.	Monthly, as incurred

Base Salary

Base salaries for the NEOs are reviewed each year by the HRCC. The HRCC may make adjustments to an NEO’s salary as a result of a change in the NEO’s duties and responsibilities and based on the performance and contribution of the executive, both on an individual basis and on the performance of the executive’s department(s), during the previous year. In reviewing the base salaries of the NEO’s, the HRCC also considers comparator group compensation studies provided by third party compensation consultants, internal pay relationships, total direct target compensation,

total employee cost and the pay position of each executive in the market (including consideration of geographic factors in determining applicable market). Any changes to CEO base salary must be approved by the Board. Changes to base salaries for other NEO’s must be approved by the HRCC.

The following table sets out the base salaries of the NEO’s as at December 31, 2025:


NEO	December 31, 2025 Base Salary ($)		December 31, 2024 Base Salary ($)		% change

Joseph C. Lambert		700,000		675,000		3.7%

Barry W. Palmer^(a)		520,000		497,035		4.6%

Andre S. Desbiens^(b)		463,881		N/A		N/A

Thomas S. Arndell^(c)		463,881		N/A		N/A

Jason W. Veenstra		415,000		400,000		3.8%

^(a)Values for Barry W. Palmer as of December 31, 2024 are stated in Canadian dollars converted from Australian dollars using Bloomberg’s 2024 average exchange rate of $0.9037.

^(b)Values for Andre S. Desbiens as of December 31, 2025 are stated in Canadian dollars converted from Australian dollars using Bloomberg’s 2025 average exchange rate of $0.900739. Mr. Desbiens was not an NEO in 2024.

^(c)Values for Thomas S. Arndell as of December 31, 2025 are stated in Canadian dollars converted from Australian dollars using Bloomberg’s 2025 average exchange rate of $0.900739. Mr. Arndell was not an NEO in 2024.

Following an analysis from the Corporation’s compensation consultant, Hugessen Consulting, at the recommendation of the HRCC, the board approved the above increases for the CEO, COO and CFO effective June, 2025. Such adjustments reflect the increased global scale of the Corporation from its significant expansion into Australia and then current market compensation levels. Base salaries of Mr. Desbiens and Mr. Arndell were approved as part of the Corporation’s acquisition of the MacKellar Group in 2023 and reflect market conditions in Australia.

Short-Term Incentive Plan (“STIP”)

STIP is the primary performance-based pay vehicle the Corporation uses to reward executives for their contributions to strong financial and safety performance in a fiscal year. Its purpose is to motivate executives to meet or exceed the Corporation’s annual financial and safety targets and to reward them to the extent that goals are achieved. All senior managers, including the NEOs, participate in the STIP.

The graphic below displays the method by which STIP is calculated for NEO’s other than the CEO. The method for the CEO does not include an Individual Performance factor, as the CEO’s individual performance is seen as 100% correlated to corporate performance (see below under “Financial Weighting” for definitions of “Bonus EBITDA” and “Bonus EBIT” and under “Safety Weighting” for definitions of “TRIF” and “SIFp”).

LOGO

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

The following describes the basic terms of the STIP:



Participants				Salaried employees active on the payment date.

Vesting				The participant must be employed by the Corporation at the time of payout or award is forfeited.

Performance Cycle				12 months

Performance Threshold				75% of the financial goals must be achieved to trigger any STIP payment.

Performance Measures				CORPORATE PERFORMANCE (50% weight) (100% for the CEO)
				Financial (90% weight of Corporate Performance)
				The Corporation’s financial targets for the business are determined by the Board annually. Targets are set based on prior financial performance and forecasted performance based on projected market conditions.
				Safety (10% weight of Corporate Performance)
				The Corporation’s safety targets for the business are approved annually by the Board. Targets are based on industry-standard metrics and prior year performance achievements.
				INDIVIDUAL PERFORMANCE (50% weight) (0% for the CEO)

				Individual goals in alignment with the Corporate strategy are cascaded to the Executive team. Corporate strategic goals and objectives are established which drive the business forward. They are set annually and reviewed and approved by the Board. Individual performance weighting is constrained by Corporate Performance (i.e. the maximum 50% weighting can only be achieved with 100% Corporate Performance).

Payout Timing				Paid in the following year once performance measures have been assessed.

Payout Range				Payment range for the CEO is 0 - 2.0x, based on a STIP payout curve approved by the Board.

				Payment range for each of the other NEOs is 0 - 1.5x, based on a STIP payout curve approved by the Board.

				There is no STIP payout if financial performance is below 75% of target. Maximum Awards may only be achieved when financial performance exceeds 125% of target performance and safety targets are 100% achieved.

Payout				Paid following the end of the fiscal year based on audited financial statements and determination of final safety metrics.

Change of Control				CEO: 2.0 x 90% of STIP target for fiscal year in which the Termination Date occurs. Other NEOs: No payment triggered. See below for details.

Termination Without Cause				CEO: 1.0 x 90% of STIP target for fiscal year in which the Termination Date occurs. CFO & COO: Receive 90% of their pro-rated STIP. Other NEOs: No payment triggered. See below for details.

Financial Weighting

For 2025, the Corporation used Adjusted EBIT and Adjusted EBITDA as the financial metrics under the STIP because the Corporation considers them good indicators of overall corporate performance. Under the STIP, the HRCC may make recommendations to the Board regarding adjustments to Adjusted EBIT and Adjusted EBITDA, thus defining “Bonus EBIT” and “Bonus EBITDA”, to eliminate factors not considered to be related to the performance of management.

Safety Weighting

Health and safety is a key priority for the Corporation and so it has incorporated safety metrics into the STIP. For 2025, the Corporation used an equal weighting of Total Recordable Injury Rate (“TRIR”) and Serious Injury or Fatality Potential Rate (“SIFp”) as the safety metric. Consistent with last year, the TRIR is an industry and nationally-recognized standard safety measure that is in line with our clients’ measurement standards for safety on mining construction sites. It is based on the total number of work-related injury and illness cases reported that require more than standard first aid treatment, as it relates to the total number of employee hours worked. The calculation for TRIR is the number of recordable cases multiplied by 200,000, divided by the total number of hours worked by all employees during the year.

Similarly, the SIFp is a measure designed to evaluate the potential for serious injuries or fatalities within the workplace. It focuses on identifying and quantifying incidents that, under slightly different circumstances, could have resulted in a serious injury or fatality. The SIFp calculation involves the number of incidents with serious injury or fatality potential multiplied by 200,000, divided by the total number of hours worked by all employees during the year. This metric helps the Corporation proactively manage and mitigate high-risk situations, ensuring alignment with industry best practices for safety management.

STIP Targets

STIP for 2025 was assessed and changed from the 2024 targets to be based on a weighted framework comprising 45% Bonus EBITDA, 45% Bonus EBIT, and 10% safety performance, consistent with the STIP framework in the 2023 program.

Safety performance accounted for 10% of the overall STIP assessment and was measured equally based on Total Recordable Injury Frequency (“TRIF”) and Serious Injury and Fatality Potential (“SIFp”), with targets of 0.5 and 0.4, respectively.

The Board approves both the financial and safety targets annually. These targets are intended to be stretch targets. The Board approved the Bonus EBITDA & Bonus EBIT targets for the year ending December 31, 2025, after taking into account the results from 2024, as well as the budget and business strategy for 2025. The Board also approved the TRIR and SIFp targets for the year ending December 31, 2025, considering the results from 2024 and the areas of focus and business plans for 2025 and onward.

STIP Awards

The HRCC makes an annual recommendation to the Board regarding the STIP award for the CEO on the basis of the Corporation’s financial and safety performance. The Board makes the final determination of the CEO’s STIP award based on the HRCC’s recommendation. The CEO makes an annual recommendation to the HRCC with respect to the STIP award for the other NEO’s after consideration and assessment of the individual achievements of the other NEO’s. The HRCC makes the final determination of the STIP awards for the other NEOs, based upon the CEO’s recommendation and the same corporate performance criteria as are applied to the CEO.

Long-Term Incentive Plan (“LTIP”)

The purpose of the Corporation’s equity-based LTIP is to motivate NEOs to achieve and increase mid and long-term Corporate performance, which will grow the value of the Corporation over the long term and generate greater returns for shareholders. Under the LTIP, incentives are awarded to NEOs 60% in the form of Performance Share Units (“PSUs”), which for the purpose of the LTIP are RSUs with performance criteria, and 40% in the form of Restricted Share Units (“RSUs”).

The following describes the basic terms of RSUs and PSUs:


Participants				Management Employees active on the grant date.
Vesting/Maturity				“Cliff-vest” or mature three years from the date of grant. Subject to limited exceptions, the participant must be employed by the Corporation at the time of vesting or award is forfeited.
Performance Cycle				Three years from the grant date.
Performance Measure				RSU settlement is based on the market value of a common share as of the maturity date.
				PSU settlement is based on the market value of a common share as of the maturity date as modified by a performance factor determined by the Board as at the time of original issuance of the PSU.
				PSU participants may receive 0% to 200% of their target grant, based on the applicable performance factor.
				Performance factor for PSU grants is based equally on four criteria: (a) TSR as compared to a peer comparator group approved by the Board; (b) adjusted earnings before interest and taxes; (c) free cash flow; and (d) adjusted return on invested capital. The first criterion is calculated based on market values, including dividends. The other criteria are based on 3-year targets approved by the Board.
Settlement Timing				Settled within 90 days following Maturity Date and in any event no later than December 31 of the year in which the Maturity Date occurs.
Equity Settlement				Settled with shares purchased on the open market by an arm’s length trust established for such purpose.
Change of Control				Become earned. See below for details.
Termination				Become forfeited. See below for details.

Under the LTIP, an RSU and/or a PSU is a right granted to a participant to receive, at the Corporation’s option, either a Common Share of the Corporation or a cash payment equivalent to the fair market value of a Common Share of the Corporation as at the maturity date. RSUs mature on the third anniversary of the grant date. Subject to performance criteria, PSUs also mature on the third anniversary of their grant date. If any dividends are paid on the NACG Common shares, additional RSUs or PSUs are credited to the participant to reflect such dividends.

The LTIP provides that, in the event of termination of a participant (with or without cause), all RSUs and PSUs that are not determined to be “earned RSUs” are immediately forfeited unless otherwise permitted under a participant’s employment agreement. In the event of the disability of a participant, or the retirement of a participant that is approved by the Compensation Committee as a “qualified retirement”, all earned RSUs will be redeemed within 30 days of the maturity date and any RSUs which have not completed their prescribed term (credited RSUs) will continue to be eligible to become earned RSUs as if the participant was still employed by the Corporation. On the death of a participant, all credited RSUs or PSUs will be deemed earned and will be redeemed within 90 days of the date of the participant’s death, or in the case of PSUs, will be settled following receipt of the results required to measure the performance criteria. Rights respecting RSUs and PSUs are not transferable or assignable other than by will or the laws of descent and distribution.

Upon a Change of Control, all outstanding RSUs that are not earned RSUs held in the participant’s RSU Account on the date the Change of Control transaction is completed will be deemed to be earned RSUs. The value of the earned RSUs will be fixed at the date of Change of Control and final payment deferred until the end of the maximum term (3 years) of the RSU. Termination provisions in the amendments provide that within 24 months following the Change of Control, if the participant’s employment is terminated by the Participant for any reason other than death, disability,

qualified retirement or good reason as defined in the plan, all earned RSUs will be immediately forfeited, unless otherwise permitted under a participant’s employment agreement (Refer to Termination Chart herein). In the case of a termination without cause, within 36 months following a Change of Control, all earned RSUs will be paid out.

LTIP Targets

Our PSU performance metrics include a balanced mix of TSR, adjusted EBIT, free cash flow, and adjusted return on invested capital. In 2025, we maintained this approach.

As with prior grants, the TSR performance metric continues to be calculated based on market values over the three-year term of the PSU’s, including dividends, relative to a benchmark group. The Board made no changes to the benchmark group for the 2025 PSU grants, which is as follows:

2025 NACG TSR Comparator Group

Aecon Group Inc.

Badger Infrastructure Solutions Ltd.

Bird Construction Inc.

Granite Construction Incorporated

Mullen Group Ltd.

Sterling Construction Company, Inc.

S&P/TSX Small Cap Index: Materials subset

S&P/TSX Small Cap Index: Industrials subset

S&P/TSX Small Cap Index: Energy subset

For 2025 grants, the performance targets and payouts for TSR in relation to the comparator group, to be determined over their three-year term, are as follows:


NACG TSR Percentile Rank relative to the Group	% of PSU Target Earned
At or above 90th Percentile (Maximum)		200%

75th Percentile (Stretch)		150%

50th Percentile (Target)		100%

25th Percentile (Threshold)		25%

The three absolute PSU performance metrics are based on 3-year targets approved by the Board. All three of these metrics (adjusted earnings before interest and taxes “Adjusted EBIT”, free cash flow and adjusted return on invested capital) are non-GAAP financial measures. Adjusted EBIT is defined as adjusted net earnings before the effects of interest expense and income taxes. Free cash flow is defined as cash from operations less cash used in investing activities including purchases funded by equipment leases but excluding cash used for acquisitions and growth capital. Adjusted return on invested capital is defined as Adjusted EBIT less tax divided by average invested capital (net debt + shareholder’s equity). See the discussion of non-GAAP financial measures in our most recent MD&A for further details.


PSU Performance Metrics for 2025 Awards

Metric	Weight	Performance Period
Relative TSR	25%	Measured 3-year point-to-point (from July to June) against TSR comparator group
Adjusted EBIT	25%	Measured 3-year performance from January preceding July grant date to December preceding June vest date (e.g., FY2025-FY2028 for July 2025 grant)
Free Cash Flow	25%
Return On Invested Capital	25%

Thomas S. Arndell		100 %		40 %		9,236		60 %		13,854

LTIP Settlement

Since 2014, the Corporation has elected to settle both RSUs and PSUs in shares. Such shares have been acquired in open-market purchases by an arm’s-length trust established by the Corporation in June of 2014 for such purpose. As at December 31, 2025, the trust held 871,244 shares. Shares held by the trust are accounted for as treasury shares in the Corporation’s financial statements.

Special Incentive Compensation

On December 9, 2024, the Human Resources and Compensation Committee resolved to grant a one-time special incentive compensation to Mr. Palmer, in his role as COO and Regional President of Australia, related to the integration of Australian operations and succession of leadership within that region. Payment of the special incentive compensation, comprising a maximum of $1,000,000, was conditional on the achievement by Mr. Palmer, by the end of 2025, of three specified goals that related to such integration and succession. On January 6, 2026, the HRCC determined that Mr. Palmer had fully achieved all three goals.

Retirement Arrangements

The Corporation does not have a pension plan. For the year ended December 31, 2025, the Corporation remitted a total of $277,808.94 for Registered Retirement Savings Plans, Non-Registered Savings Plans (Group Investment Accounts), and Superannuation for the NEOs.

Benefit Plans

The Corporation provides NEOs with health, dental, disability and insurance coverage through benefit plans paid for by the Corporation.

Perquisites

NEOs receive a limited number of perquisites that are consistent with market practice for individuals at this level. These include a vehicle allowance, reimbursement for fuel purchases, and company provided smart phone or smart phone allowance.

Core Comparator Group

The HRCC reviews and approves a core comparator group as a reference in establishing target pay. This group differs somewhat from the TSR comparator group discussed above, as the factors used in assessing competitive compensation are somewhat different than the factors used in assessing Corporate financial performance. For the compensation comparator group, the Board chooses companies that meet the following criteria:

(a)

compete with NACG for customers and revenue;

(b)

compete with NACG for executive talent, particularly in the Alberta labour market;

(c)

compete with NACG for equity or other capital;

(d)

are in the same or similar industry, such as construction and engineering or oil and gas equipment and energy services;

(e)

are of comparable size, in terms of revenue, assets, EBITDA, market capitalization and enterprise value; and

(f)

have reliable benchmark compensation information available.

Certain direct competitors are not included in our comparator group because they are private corporations or partnerships or smaller divisions of larger corporations with insufficient compensation information available for them. The use of comparative market data is just one of the factors used in setting compensation for NEOs. NEO compensation could be higher or lower than the comparator data as a result of individual performance, industry knowledge base, professional degrees and certifications, relevant skills, abilities, years of service, executive experience and market conditions (including variances by geographic region).

The following table sets out NACG’s current compensation comparator group, showing that NACG is positioned at the 16^thpercentile for total enterprise value (“TEV”),3^rd percentile for market capitalization, 26^th percentile for revenue, 85^th percentile for EBITDA, 7^th percentile for net income, and 49^th percentile for total assets:

2025 Compensation Decisions Regarding NEOs

STIP Program Objectives and Results

For the year ended December 31, 2025, the following Corporate STIP targets were recommended by the HRCC and approved by the Board under the STIP program, with achievement as indicated:


Metric	2025 Target and Achievement	Board- Approved STIP Score

Financial Performance (90% weighting)

Bonus EBIT (45%)	The Corporation achieved $118.2M Bonus EBIT from continuing operations, which was 49.4% of the target of $239.5M.		14.2%
Bonus EBITDA (45%)	The Corporation achieved $341M Bonus EBITDA from continuing operations, which was 76.7% of the target of $444.8M.		14.2%

Safety Performance (10% weighting)

Total Recordable Injury Rate (“TRIR”)	In 2025, there were a total of twelve injury cases, resulting in a TRIR of 0.39 Target was to achieve a TRIR of 0.50 or less.		10.0%
Serious Injury or Fatality Potential Rate (“SIFp”)	In 2025, there were a total of six SIFp incidents, resulting in an SIFp of 0.08. Target was to achieve a SIFp of 0.40 or less.		10.0%

For the fiscal year 2025, the financial metrics used in the STIP performance metrics were Bonus EBIT and Bonus EBITDA, equally weighted and comprising 90% of the overall Corporate performance measures. With respect to each of the Bonus EBITDA and Bonus EBIT targets, the Board approved a STIP payout curve that provides for payout of 0% of target payout if less than 75% of target performance is achieved, 25% of target payout if 75% of target performance is achieved, 75% of target payout if 87.5% of target performance is achieved, 100% of target payout if 100% of target performance is achieved and a maximum payout of 150% of target payout if 125% or more of target performance is achieved (with intermediate achievement being interpolated on a linear basis) and with maximum payout for the CEO being 200% of target payout, as per the CEO’s written employment agreement. This payout curve, as applied to achievement, determines the actual STIP score stated above.

For the fiscal year 2025, the Corporation achieved $118.2 million in Bonus EBIT, amounting to 49.4% of the target, and $341 million in Bonus EBITDA, amounting to 76.7% of the target. These achievements resulted in a STIP payout on financial metrics equal to 14.2% of target payout.

We continue to strive for zero workplace injuries. For that reason, safety performance continues to be an important factor to achieving our STIP goals. In 2025, the Total Recordable Injury Rate (“TRIR”), which is an industry and nationally-recognized standard safety measure, was used as one of two safety metrics. It is based on the total number of work-related injury and illness cases reported that require more than standard first aid treatment, as it relates to the total number of employee hours worked (refer also to the EXECUTIVE COMPENSATION - Short-Term Incentive Plan in this document for the calculation for TRIR).

In 2025, there were fourteen recordable injuries resulting in a TRIR of 0.39, with a recorded 7.1 million exposure hours. With a target TRIR of 0.50 or less, this portion of the safety performance measure was achieved.

In 2025, there were three SIFp critical incidents, resulting in a SIFp of 0.08, with a recorded 7.1 million exposure hours. With a target SIFp of 0.40 or less, this portion of the safety performance measure was achieved.

Combined financial and safety performance, once weighted, resulted in an overall STIP score of 24.2%.

For Mr. Desbiens and Mr. Arndell, STIP was calculated per the above with the exclusion of the Nuna Group of Companies financials, based on achieving $122.8M Bonus EBIT and $343.5M Bonus EBITDA, resulting in an overall STIP score of 28.8% once weighted.

Each member of the executive team is accountable for achieving certain results based on the Corporation’s strategic objectives and financial and safety targets. The degree to which the Corporation achieves these goals is the degree to which the NEOs will see their compensation in the form of “at-risk” pay increase. Because much of the “at-risk” pay is directly aligned with the Corporation’s share price and financial success, the variable pay is strongly aligned with shareholders’ interests. The following are the major achievements of each NEO in 2025 and their respective awards:

LOGO

Joseph C. Lambert

LOGO

Mr. Lambert’s base salary was increased to $700,000 effective June 1, 2025.

Under the terms of the STIP Mr. Lambert’s annual incentive award was targeted at 100% of annual base salary and was entirely linked to achievement of the Corporation’s financial and safety targets. Pursuant to the terms of Mr. Lambert’s employment agreement, upon his departure he was entitled to receive his STIP attributable to 2025. Because Mr. Lambert’s departure from the Corporation came before final determination of STIP, the amount was estimated, resulting in him receiving a STIP payout at 25% of target, despite a 24.2% Corporate achievement. That resulted in a STIP award of $172,415, for the year ended December 31, 2025.

Under the terms of the LTIP Mr. Lambert’s annual award was targeted at 250% of annual base salary, or $1,750,000 in grant date value, issued 60% as PSUs and 40% as RSUs, with achievement being determined over the three-year term of the PSUs and RSUs.

Mr. Lambert’s total direct compensation at target for 2025 was comprised of 78% of pay “at-risk” through short- and long-term incentive plans, with 56% of his target pay mix tied to the Corporation’s share price performance through the annual long-term incentive plan award. Also, 60% of his variable long-term compensation is in the form of PSUs, which have relative TSR and other financial performance metrics.

As VP, Asset Management, Mr. Arndell is responsible for overseeing the complete lifecycle of the Corporation’s assets, from acquisition to disposal. This role ensures maximum asset performance by managing component health, maintenance planning, and overall equipment profitability. Mr. Arndell leads teams focused on condition monitoring, maintenance scheduling, and inventory management to enhance operational efficiency and reduce downtime. In collaboration with both operating and maintenance teams, Mr. Arndell provides strategic leadership and best-practice oversight to support services and programs that drive excellence in asset management.

Mr. Arndell’s base salary is $515,000 AUD which is $463,881 CAD (converted using Bloomberg’s 2025 average exchange rate of $0.900739).

Under the terms of the STIP, Mr. Arndell’s annual incentive award is targeted at 100% of annual base salary and is linked to achievement of corporate results and individual achievements. Mr. Arndell’s individual achievements for 2025 included the following:


Execution Excellence:				Focus on safety practices and trends (e.g. reduction in incidents as a result of incorrect practices such as lifting, towing and transportation of goods) fostering a culture of problem solving through engineering excellence. Led the fleet and maintenance team to work with DGI in effort to increase value of assets upon disposal. This improvement enabled the Corporation to strategically increase the disposal value of assets and remove these assets from coming back into the oil sands region being used by a competitor. Developed a plan to reduce inventory levels by 50%. This plan has been in place for four months and has achieved a 35% inventory reduction to date. Reduction has occurred through the rationale of inventory level compared to the level of work on hand and achievement through improved inventory control practices, increased discipline on sites, and centralized purchasing.
Growth and Diversification:				Formulated a broad strategy to mobilize assets across NACG’s companies. This further strengthens the asset teams of each entity and allows them to support operations and business development with a more expansive offering of machines. Additionally, the strategy has opened up new opportunities outside of NACG existing clients and expanded the geographic footprint. Continuing with opportunities to strengthen partnerships with OEM’s, such as Finning, in effort to increase support and buying power. By fostering these relationships, NACG is offered reduced purchase price on new machines, rebates on parts spend, and preferential treatment on supply of labour. Devised a strategy of expanding channels to dispose of equipment. NACG has historically sent equipment that has reached their bench life (or is no longer required) to auction houses. This over-reliance on auction houses does not always maximize sale price. Options of brokers and sending assets to different markets can deliver greater returns and remove disposable equipment from competing in existing regions.
Corporate Excellence:				Lead the ongoing simplification and refinement of NACG asset management systems. By streamlining these internal processes, internal stakeholders have been given clarity to proactively mitigate risks, formulate action plans, and ensure operational compliance at all times. Ceased data analytics and performance management division known as Telematics. Capital required to offer a platform comparable to others on the market was unsustainable. NACG has retained experts in this field who are now evaluating various platforms to be rolled out. These platforms come with a reduced cost per operating hour and increased functionality for both maintenance, planning, and operations. This in turn will drive efficiencies not previously realized.

Share Ownership Guidelines

As part of the Corporation’s effort to align executive interests with shareholder interests, it has adopted share ownership guidelines for senior executive officers. The guidelines must be achieved within five years from the date the senior executive officer is appointed as a member of executive management and must be maintained thereafter. All share ownership is to be in the form of equity in the Corporation, in each case represented by NACG Common Shares, DSUs or RSUs. PSUs are not counted as they have a performance component which could result in zero payout. The value of NACG Common Shares, DSUs, and RSUs representing the compliance level is determined by the greater of market value or book value of the holdings.

The following table summarizes compliance with the share ownership guidelines for each NEO as at December 31, 2025:

⁽ⁱⁱ⁾ NEO Total Direct Compensation represents: Salaries Earned, Share Based Awards, STIP Awards, and other nominal cash compensation received by the NEOs in the applicable reporting year. Refer to the Summary Compensation Table herein.

The graph above shows the total direct compensation of the Corporation’s NEOs over the same five-year reporting period (see also the Summary Compensation Table within this discussion and analysis). The total direct compensation of our NEOs generally follows a similar trend to the NACG share value on the TSX, where in a reporting year, NACG share value was lower, the NEO total direct compensation was lower; conversely when the NACG share value increased, the NEO total direct compensation also increased.

In considering NEO Total Direct Compensation over the previous five years, as set out above, it should be noted that:

•

2021 served as a transition year with the Corporation having both an Executive Chair and a CEO. That resulted in an unusual and temporary one-year increase in NEO Total Direct Compensation in 2021. With the position of Executive Chair being eliminated as of January 1, 2022, NEO total direct compensation normalized as a result.

•

2025 also had a rise in aggregate NEO compensation owing to two factors. Firstly, the one-time special incentive compensation paid to Mr. Palmer in relation to Australian integration and succession materially increased overall NEO compensation. Secondly, the NEO mix changed in 2025, with two new Australia-based NEO’s being added. Due to differing compensation market conditions in Australia as compared to Canada,

total compensation for those NEOs was significantly higher than the two Canada-based executives who were consequently removed from the list of NEOs.

Human Resources And Compensation Committee

The Human Resources and Compensation Committee (the “HRCC”) is comprised entirely of independent Board members. This approach ensures that no conflict of interest exists between Committee members accountable for making executive compensation decisions and the executive management itself. Each HRCC committee member brings human resources and executive compensation oversight, as well as financial knowledge and industry experience. The members of the HRCC, as of the fiscal year end, December 31, 2025, were:



Name of Committee Member	Role on Committee	Direct Executive Compensation Experience

HRCC RESPONSIBILITY

The HRCC is charged with the responsibility of assisting the Board in meeting its responsibilities in relation to: (a) board and executive compensation; (b) oversight of human resource policies for the Corporation and its subsidiaries; and (c) oversight of executive succession and development.

Compensation Governance

The Board has approved a Committee Charter for the HRCC which provides that the HRCC is responsible to:

(a)

review and recommend to the Board for approval the Corporation’s general compensation philosophy, policies and guidelines;

(b)

review and recommend to the independent members of the Board for approval annually the corporate goals and objectives relevant to the compensation of the CEO;

(c)

review and recommend to the independent members of the Board for approval the compensation package for the CEO, including without limitation, base salary, annual incentive compensation, retirement, health and welfare benefits and perquisites;

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

(d)

review and approve, at the recommendation of the CEO, the compensation package for the Executive Management of the Corporation, other than the CEO, including without limitation, base salaries, annual incentive compensation, retirement, health and welfare benefits and perquisites. In the Charter, “Executive Management” includes the President and CEO, COO, CFO, CLO and CPO;

(e)

review and recommend to the Board for approval the structure, implementation, participation, amendments or termination of all long-term incentive compensation programs, including but not limited to the Deferred Share Unit (DSU) Plan, the Performance Share Unit (PSU) Plan and Restricted Share Unit (RSU) Plan;

(f)

review and recommend to the Board for approval the compensation package for the Committee Chairs and other directors;

(g)

review and recommend to the Board for approval the recruitment, evaluation and succession plans for the CEO;

(h)

review and approve the recruitment, appointment, evaluation and succession plans for the Executive Management of the Corporation, other than the CEO;

(i)

conduct or authorize investigations into any matter within its scope of responsibilities;

(j)

retain and compensate independent counsel, outside experts (including compensation consultants) or other advisors to advise and assist the Committee with respect to its responsibilities, including approval of applicable fees and other terms and conditions of retention;

(k)

(l)

meet and communicate directly with the Corporation’s officers, outside counsel and consultants, all as the Committee may deem necessary;

(m)

access all documents of the Corporation that the Committee may deem relevant to it in carrying out its responsibilities; and

(n)

undertake any other activity that may be reasonably necessary for the Committee to carry out its responsibilities as set out in the Charter.

Risk Management

As a key part of its oversight of Board and executive compensation, the HRCC considers the implications of the risks associated with the Corporation’s compensation policies, including obtaining the advice of external compensation experts and both internal and external legal counsel to identify and mitigate such risks. The key risks identified by the HRCC in relation to compensation are: (a) ensuring alignment of executive behavior with shareholder interests; (b) ensuring executives are not rewarded for taking undue risks outside the established risk tolerances for the Corporation; (c) ensuring compensation is at market levels to be able to attract and maintain talented executives while not over-paying for their services; (d) ensuring the Corporation’s compensation plans encourage a balance between short-term and long-term results. The HRCC believes that it has implemented policies, procedures and compensation plans and mechanisms that mitigate all of these risks, including taking the following actions:

•

Making a majority of the targeted annual compensation of each NEO “at-risk” and contingent on achieving predetermined short-term, medium-term and long-term objectives tied to financial performance, shareholder value and safety;

•

Regularly benchmarking base, variable and total compensation against a compensation;

•

Selecting a compensation comparator group of organizations, in consultation with external compensation consultants, as relevant for compensation benchmarking purposes;

•

Structuring the Short-term Incentive Plan (STIP) with a balanced, diversified mix of financial and non-financial performance measures, each intended to improve different elements of the Corporation’s business;

•

Determining STIP targets on the basis of financial and safety metrics, thereby placing an emphasis on the Corporation’s financial and safety performance within that incentive plan;

•

Setting a threshold for STIP payout, established to compensate strong Corporation performance against stretch targets (while also capping the STIP payout for the NEOs);

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

•

Providing the executive team members with the option of converting up to 50% of their STIP payout to DSUs, where more of their pay is invested in the Corporation and tied to share price;

•

Ensuring the Long-Term Incentive Plan (LTIP), including PSU performance criteria, properly reflects and aligns with shareholder expectations and interests;

•

Implementing a system whereby RSUs and PSUs are paid out in shares of the Corporation rather than in cash, thereby encouraging share ownership by a broad group of the Corporation’s management employees;

•

Adopting formal share ownership guidelines for NEOs, which require them to hold a target dollar value of equity in the Corporation while employed in an executive position and confirming with independent compensation consultants that these guidelines are in-line with market best practices;

•

Implementing a vesting period of up to three years for RSUs and PSUs to align executives’ interests and efforts with those of shareholders over the long term;

•

Granting RSUs and PSUs annually, to provide overlapping performance cycles that require sustained levels of performance to achieve a consistent payout;

•

Providing strong oversight of the executive compensation program by using discretion to adjust metrics or payouts based on results, events and/or individual circumstances;

•

Implementing a formal anti-hedging policy which prohibits directors and employees, including executive officers, from short-selling or hedging securities of the Corporation, including a prohibition on purchasing financial instruments that are designed to hedge or offset a decrease in market value of securities granted as compensation or otherwise held directly or indirectly by the director or employee; and

•

Implementing a formal executive compensation claw-back policy which ensures executive officers are not able to benefit through an overpayment of performance-based compensation that is based on an error or omission in determining the compensation, the misconduct of the executive officer or a restatement of financial results (other than a restatement caused by a change in applicable accounting rules or interpretations).

Independent Advice

The HRCC and management use the services of specialized and independent compensation consultants to assist in carrying out their mandate with respect to executive appointments and compensation governance.

The consultants may be engaged to:

•

provide information and independent advice to assist in developing the appropriate total compensation philosophy and structure for the current NEOs and potential executive positions;

•

assist management in the development of the various programs within our compensation framework;

•

perform studies of market comparator groups to evaluate the Corporation’s total compensation programs;

•

provide recommendations to the HRCC such as appropriate compensation structure and composition of appropriate compensation comparator groups; and

•

provide custom reporting data based on the compensation comparator group financial results.

It is not a requirement of the HRCC to obtain prior approval from the Board to retain the services of specialized or independent compensation consultants. The HRCC may engage the services of a consultant to analyze and mitigate compensation risk to the Corporation. In 2025, the Corporation retained Hugessen Consulting, Inc. (“Hugessen”), an independent compensation consultant, to assist in determining compensation for executive management and directors, and Mercer Canada (“Mercer”) for assist in determining certain specific compensation-related performance criteria.

The HRCC Chair may meet privately with the independent consultant before meetings where compensation is discussed to ensure that important issues receive appropriate attention. In addition, the HRCC meets with the independent advisor in camera without management present when compensation is reviewed.

Both Hugessen and Mercer were engaged throughout 2025 by the HRCC as independent compensation consultants to provide advice to the HRCC regarding executive & director compensation, board effectiveness, the composition of the Corporation’s TSR comparator group and to provide total shareholder return reporting in comparison to the

Deferred Compensation Plans

The CEO, CFO, and COO are given the opportunity to take up to 50% of their annual STIP in the form of Deferred Share Units “DSUs”. This compensation component is encouraged by the Board, as it increases ownership in the Corporation and promotes the pay for performance principle, given that the value of DSUs exactly tracks the value of shares and must be held for the holder’s entire tenure with the Corporation. See below under “Deferred Share Unit Plan” in the Section on Board of Directors Compensation.

Termination and Change of Control Benefits

The Corporation has entered into employment agreements with each of the NEOs. The employment agreements clearly define the terms under which an NEO will be compensated in the event of his resignation, termination or in the event of a change in control and mitigates the financial risk to the Corporation. The CEO’s employment agreement entitles him to receive payments in the event of a change in control of the Corporation on a “Double Trigger” basis. Compensation must be paid to the CEO if the Change of Control is followed by: (a) termination of the CEO by the Corporation without cause; or (b) where the CEO resigns with “good reason”. The term “good reason” is defined as an adverse change, or series of adverse changes, to the CEO’s role after a change in control without the agreement of the CEO that results in a substantial diminishment of the CEO’s responsibilities, status or compensation or that otherwise constitutes constructive dismissal at common law. None of the employment agreements with the other NEOs entitles the NEO to receive a payment in the event of a change in control of the Corporation. The table below describes how each compensation element is treated for each NEO in the event of termination or in the event of a change in control:

Board of Directors Compensation

Compensation Philosophy and Approach

The compensation of non-employee Directors is intended to attract highly qualified individuals with the capability to meet the demanding responsibilities of Board members and to align the interests of directors with those of the Corporation’s shareholders. Non-employee director compensation is not incentive-based.

The HRCC assesses the adequacy and form of compensation paid to Directors in order to ensure that their compensation is competitive and reflects their responsibilities as directors. Periodically, the HRCC benchmarks directors’ compensation against compensation paid by Canadian public companies comparable in size and scope to the Corporation and engages the services of a compensation consultant to report on relevant benchmark data and recommend appropriate compensation for directors.

^(a)Award amounts reflect grant date fair market value of DSUs as calculated in accordance with the deferred share unit plan. The fair market value is based on the value of a share on the market (TSX) for the five-day or twenty-day (as applicable to the process at the time of grant) preceding the grant date. The number of DSUs is calculated by dividing the DSU award value by the fair market value.

Under the Corporation’s director compensation program, which was implemented as of January 1, 2024 after consultation with Hugessen, each of the Corporation’s non-employee Directors receives an annual retainer of $200,000, with the chairs of each of the Board committees receiving additional annual retainers as follows: Board Chair - $35,000, Chair of Audit & Risk Committee - $18,000, Chair of Human Resources and Compensation Committee - $15,000, Chair of Governance and Sustainability committee - $10,000, and Chair of the Operations Committee - $10,000. In addition, each director is entitled to an additional $3,000 CDN per day of travel for board business, to the

extent travel is from North America to another continent or vice versa. Notwithstanding the foregoing, the Board agreed, as of January 1, 2022, to provide Mr. Ferron with a retainer of $250,000 per year as compensation for his serving as Chair of the Board plus an additional $100,000 for serving as Chair of the board of one of the Corporation’s key joint ventures. That total payment of $350,000 is in place of the compensation he would otherwise be entitled to as Chair. Mr. Pinney received $35,000 for his service as Lead Director in 2024, but neither he nor any other director is serving as Lead Director in 2025. Mr. Lambert did not receive any remuneration in 2025 for serving as a director over and above his compensation as a current executive. Mr. Palmer was not a director in 2025. All Directors are reimbursed for reasonable out-of-pocket expenses incurred in connection with their services pursuant to the Corporation’s policies. Directors do not receive option-based awards, non-equity incentive plan compensation, pension compensation or any other compensation not detailed in this section.

Deferred Share Unit Plan

The Corporation’s Deferred Share Unit Plan (“DSU Plan”) was approved on November 27, 2007, by the Corporation’s Board and became effective on January 1, 2008. DSUs may be granted to each member of the Board as well as to certain senior management employees approved by the Board as being participants in the DSU Plan. The DSU Plan provides that a director may elect to receive up to 100% of their fees in the form of DSUs, but that for so long as the that director is in compliance with applicable Share Ownership Guidelines, he or she may elect to receive as little as 0% of their compensation as DSUs. DSUs vest immediately upon grant and may be redeemed only when the director ceases to hold office, whereupon all DSUs will be redeemed by the Corporation within 21 days following: (a) in the case of directors that are U.S. taxpayers, the date of such termination; and (b) in the case of all other directors, by December 1 of the calendar year immediately following the year by which such termination takes place (unless an earlier date is elected by the director after termination). A director has no further rights respecting any DSU which has been redeemed. As and when dividends are paid on the Corporation’s shares, DSUs are issued to holders in an amount equivalent to the dividend that would have been earned if the DSU was a share. In this manner, DSUs align director interests with shareholder interests, as DSUs exactly track the value of shares and must be held by directors for no less than their full tenure with the Corporation.

The following described the basic terms of the DSUs issued in 2025:



Participants				Executives and Directors active on the grant date.

Vesting				Immediately “Earned” on date of grant.

Settlement Timing				Settled within 21 days of the Redemption Date, which is: (a) December 1st of the calendar year immediately following the year in which the termination of service occurs for Canadian NEOs or Directors; or (b) the date that termination of service occurs for U.S. resident NEOs or Directors.

Cash Settlement				Settled in cash based on the fair market value of a common share as of the Redemption Date. The fair market value is based on the value of a share on the TSX for the five trading days preceding the Redemption Date.

Change of Control				Deemed to remain as earned, but no settlement is triggered.

Share Ownership Guidelines

One way that Board members demonstrate their commitment to the long-term success of the corporation is through share ownership. The Board has established Share Ownership Guidelines for directors which must be met within five years of being elected as a director and must be maintained thereafter. The Board periodically reviews its Share Ownership Guidelines, including having such guidelines reviewed by its compensation consultant Mercer. Currently, directors are required to hold $600,000 of equity in the Corporation (i.e. 3x total base annual compensation), with the Chair of the Board being required to hold $705,000 of equity in the Corporation (i.e. 3x the amount of total base annual compensation plus chair fee), in each case represented by NACG Common Shares and/or DSUs. The value of NACG Common Shares and DSUs representing the compliance level is determined by the greater of market value or book value of the holdings.

All current Directors comply with, or are on track to be in compliance with, these Share Ownership Guidelines.

Interest of Informed Persons in Material Transactions

At no time since the beginning of the Corporation’s last completed fiscal year, has any informed person of the Corporation (as such term is defined under applicable securities laws), any proposed director of the Corporation or any associate or affiliate of any such informed person or proposed director had any material interest, direct or indirect, in any transaction or proposed transaction which has materially affected or would materially affect the Corporation or any of its subsidiaries.

CORPORATE GOVERNANCE

Independence

The Board has determined that each of the directors, other than Barry Palmer, is an independent director within the meaning of the rules of the New York Stock Exchange applicable to foreign private issuers and applicable Canadian securities laws. Mr. Palmer currently holds the position of President and Chief Executive Officer with the Corporation and is therefore not considered independent.

National Policy 58-201 – “Corporate Governance Guidelines” of the Canadian Securities Administrators recommends that boards of directors of reporting issuers be composed of a majority of independent directors. Further, listing requirements of the New York Stock Exchange applicable to foreign private issuers require that the Board be composed of a majority of independent directors. With six of seven current and proposed directors being independent, the Board is, and will be, composed of a majority of independent directors.

To facilitate open and candid discussion among the Corporation’s independent directors, the Board holds in camera sessions which exclude any non-independent directors and members of management. In camera meetings are held as part of every regularly scheduled Board meeting and are led by the Board Chair (or by the Lead Director where one has been appointed). In the fiscal year ended December 31, 2025, the Board held five in camera sessions that excluded non-independent directors and members of management. Except for those in camera sessions, there were no formal separate meetings of independent Board members that took place.

Directorships with Other Issuers

Currently, the following directors serve on the boards or act as trustees of other public companies, as listed below. As of the date of this Circular no Directors of the Corporation sit together on boards of other public corporations.

Code of Conduct and Ethics Policy

In order to ensure that directors exercise independent judgment and to encourage and promote ethical standards and behavior, the Board has a written Code of Conduct and Ethics Policy (the “Code”) setting out general statements of conduct and ethical standards to be followed by all of the Corporation’s directors, officers and employees. A copy of the Code may be obtained at the Corporation’s website at www.nacg.ca.

All NACG personnel are required to report any conduct which they believe, in good faith, to be a violation or apparent violation of the Code or any applicable law or regulation. The Code outlines several channels for reporting violations, including communication with an immediate supervisor, the Human Resources Department, the Chief Executive Officer or any Vice President, or any Board member. In instances where anonymity is desired, personnel are directed to contact ClearView Connects which is an independent ethics reporting firm. ClearView Connects is available 24 hours a day, 365 days a year to all employees, contractors, and customers. ClearView Connects is accessible via the Corporation’s external website as well as on internal intranet sites. The Corporation’s Ethics Reporting Policy, which is available at www.nacg.ca, provides further detail about the options for reporting violations of the Code or of any other NACG policies.

In all cases there are two reviewers for each reported violation, which ensures an effective independent review and a control over segregation of reviewing responsibility to ensure that reported violations are investigated appropriately and thoroughly. For serious violations of the Code, the Audit & Risk Committee Chair or the Board Chair will be advised immediately of the reported violation. All reported violations are summarized and provided to the Audit & Risk Committee at least quarterly. The Audit & Risk Committee Chair and the Board Chair will have access, at all times, to the status and content of Reported Violations.

Retaliation by the Corporation or by the Corporation’s personnel against anyone who acts in good faith in reporting any violation of the Code is expressly prohibited. All reporting of violations of the Code are required to be held by the recipient of the report in strict confidence except as may be required to address the violation or otherwise as disclosure may be required by law. This generally provides protection from work-place harassment or retaliation. In the event retaliation is a concern for a reporter, however, management will take steps, including reassignment to a different geographic worksite, if necessary, to ensure that supervision and reporting channels are structured to avoid any real or perceived direct or indirect pressure, intimidation or retaliation with respect to a reporter.

Compliance with the Code is a condition of employment with the Corporation. All members of the Board, officers, salaried staff, superintendents and nonunion hourly professionals, management and supervision are required to take an online course on an annual basis that explains the content, meaning and application of the Code. As such, personnel are also required to read and reaffirm their agreement to comply with the Code. Field and maintenance hourly workforce are required to read the Code and to sign an acknowledgment form upon commencement of employment.

The Code provides additional safeguards to ensure that directors exercise independent judgment in considering transactions and agreements in respect of which a director or executive officer has a material interest by requiring that all personnel avoid any activity which creates or gives the appearance of a conflict of interest between an individual’s personal interests and the Corporation’s interests. Specifically, the Code provides that, unless a waiver is granted, no personnel shall (i) seek or accept any personal loan or guarantee of any obligation or services from any outside business, (ii) act as a consultant or employee of or otherwise operate an outside business if the demands of the outside business would interfere with the employee’s responsibilities to the Corporation, (iii) conduct business on behalf of the Corporation with a close personal friend or immediate family member, or (iv) take for themselves opportunities that arise through the use of the Corporation’s property or information or through their position within the Corporation.

Governance and Sustainability Committee and Nomination of Directors

The Governance and Sustainability Committee is responsible for identifying, assessing and recommending to the Board new nominees for election to the Board by the shareholders at annual meetings or to fill vacancies on the Board that occur between shareholder meetings. The Committee normally identifies potential new candidates through a combination of external search firms and by direct referral from Board members or others. Potential candidates are vetted through a process of due diligence and are also interviewed by members of the Committee, the Chair and by other members of the Board. In addition to its role in identifying, assessing and recommending new candidates for Board nomination, the Committee also conducts an annual review with respect to re-nomination of incumbents and makes recommendations to the Board regarding corporate governance matters, policies and practices generally, including with respect to environmental and social governance matters.

In accordance with the listing requirements of the New York Stock Exchange and applicable Canadian securities laws, the Board has affirmatively determined that the Committee is composed solely of independent directors. Our Board has adopted a written charter for the Governance and Sustainability Committee that is available on our website at www.nacg.ca. The Governance and Sustainability Committee is currently composed of Bryan Pinney, Maryse Saint-Laurent and Kristina Williams, with Ms. Saint-Laurent serving as Chair.

Human Resources and Compensation Committee

The Human Resources and Compensation Committee is charged with the responsibility for supervising Board and executive compensation policies for the Corporation and its subsidiaries, overseeing administration of employee incentive plans, reviewing officers’ salaries, approving significant changes in executive employee benefits and recommending to the Board such other forms of remuneration as it deems appropriate. The Board’s process for determining compensation for the Corporation’s executives is described in extensive detail above under “Compensation Discussion and Analysis”. The process for determining Board compensation involves obtaining the advice of independent compensation consultants to determine a market-competitive compensation package that aligns with the interests of shareholders and is comparative to the Board compensation paid by our compensation comparator group. Based on such advice, the Committee makes periodic recommendations to the Board regarding changes in compensation. For a more detailed description of the roles and responsibilities of the Human Resources and Compensation Committee, see our most recently filed Annual Information Form, which can be found on SEDAR+ at www.sedarplus.com and on the Corporation’s website at www.nacg.ca. In accordance with the listing requirements of the New York Stock Exchange and applicable Canadian securities laws, the Board has affirmatively determined that the Committee is composed solely of independent directors. Our Board has adopted a written charter for the Human Resources and Compensation Committee that is available on our website at www.nacg.ca. The Human Resources and Compensation Committee is currently composed of Thomas Stan, Bryan Pinney and Maryse Saint-Laurent, with Mr. Stan serving as Chair.

Audit & Risk Committee

The Audit & Risk Committee recommends independent public accountants to the Board, reviews the quarterly and annual financial statements and related management discussion and analysis, press releases and auditor reports, and reviews the fees paid to our auditors. The Audit & Risk Committee approves quarterly financial statements and recommends annual financial statements for approval to the Board. It also oversees approval of our risk management policies, processes for monitoring risk management performance, and reviewing the risks and related risk mitigation plans within our strategic plan. For a more detailed description of the roles and responsibilities of the Audit & Risk Committee, including the full text of its written charter, see our most recently filed Annual Information Form, which can be found on SEDAR+ at www.sedarplus.com and on the Corporation’s website at www.nacg.ca.

The Audit & Risk Committee is currently composed of Bryan Pinney, John Pollesel and Kristina Williams, with Mr. Pinney serving as Chair.

Operations Committee

The Operations Committee is responsible for monitoring, evaluating, advising and making recommendations on matters relating to the health and safety of our employees, the management of our health, safety and environmental risks, due diligence related to health, safety and environment matters, as well as the integration of health, safety, environment and social responsibility into our business practices, reviewing and approving tenders and contracts above certain risk thresholds and any other matter where Board guidelines require approval at a level above CEO, and reviewing and monitoring the Corporation’s insurance policies.

Board Assessment

The Board, its committee and the directors are regularly assessed with respect to their effectiveness and contribution. At each regular quarterly meeting of the Board and each of its committees, an in camera session is held separate from management in which, among other things, the Board and each committee perform self-assessments. Such quarterly assessments are conducted through frank and open discussion among Board members or committee members, as applicable. On an annual basis the Board conducts a more formal peer review survey. Under the annual peer review process, the Chief Legal Officer of the Corporation circulates questionnaires to be filled out on a confidential basis by all directors addressing such topics as independence, roles and responsibilities, leadership, director selection, competencies and development, agendas meetings and minutes, Board relationships and communication, information and internal reporting, Board dynamics and decision making, strategic responsibilities, financial reporting and internal controls and individual director effectiveness and contribution. The responses to such surveys are reviewed by the Chair of the Governance and Sustainability Committee and the Chair of the Board. One-on-one interviews with directors are conducted by the Chair of the Board to obtain any comments or input regarding Board function and effectiveness beyond the responses in the survey. The Chair of the Governance and Sustainability Committee also conducts one-on-one interviews with the other directors with respect to the Chair’s effectiveness. The Chair of the Board and Chair of the Governance and Sustainability Committee present a summary of key comments or issues identified to the Board as a whole for discussion. Any changes resulting from such discussion are then implemented.

Director Term Limits

The Corporation has not adopted term limits for its directors. In the view of the Corporation, optimal governance is aided by a combination of Board renewal and Board continuity. The Governance and Sustainability Committee considers and assesses Board and committee composition on a regular basis as well as performing peer review assessments with an eye to ensuring the Board and its committees are comprised of persons having the qualifications, skills, knowledge, experience and expertise necessary for effective governance of the Corporation. Any shortcomings identified by the Governance and Sustainability Committee are brought forward to the Board and recommendations for recruitment or other change are made as are determined by the Board to be in the best interests of the Corporation. Our seven nominees, who are all also current members of the Board, have an average tenure on the Board of 8 years and 7 months.

Board and Senior Management Diversity

We consider diversity and inclusion to be important building blocks of our company culture. Paired together, these two fundamental forces help build a corporate culture that encourages, supports, and celebrates the diverse voices of our employees. It fuels our innovation and connects us closer to our customers and the communities we serve. Part of our strategy to build this inclusive and diverse base includes strengthening and diversifying our Board and senior management teams. The Board believes that having a diversity of perspectives and viewpoints among its members and among senior management is a significant benefit to the Corporation. To these ends, the Corporation has established a written Board and Senior Management Diversity Policy that requires the Board and the Governance and Sustainability Committee, when identifying, nominating, and selecting candidates for appointment or election to the Board and to senior management positions, to consider:

(a)

the qualifications, skills, knowledge, experience and expertise of each potential candidate and the way in which the same would complement the qualifications, skills, knowledge, experience and expertise of existing Board members or members of senior management; and

(b)

whether each potential candidate is a woman, Aboriginal person, person with disabilities or member of a visible minority and the extent to which such candidate’s appointment would advance the Corporation’s diversity objectives.

Currently, women hold two out of seven Board positions, or 28.6%, of all Board positions. Upon election of the directors put forward for nomination at the Meeting to which this Circular relates, those numbers will stay constant. The Corporation does not presently have a target for representation of women on the Board as it feels that, given its small Board size, having such a target would unduly limit it in conducting Board recruitment.

Currently, two out of nine members of the Corporation’s senior management, or 22.2%, are women. The Corporation has not set a target for representation of women in senior management within the Corporation. The Corporation’s senior management group is small, turnover among the group is not expected in the near future and the Corporation does not feel that it is prudent at the present time to increase the size of the senior management group. The

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

Corporation has implemented a plan to invest in leadership development for women employees within its “senior leadership group”, which it defines as its senior management plus the group of managers below the senior management, and within the Corporation generally, in an effort to reinforce leadership knowledge, skills, and abilities required to ultimately fill senior management positions. We believe that taking this approach gives us the best opportunity to develop future executives from within the Corporation. . We have also implemented a succession and development program designed to identify key women within the organization to train for management and supervisory positions.

The Board and the Governance and Sustainability Committee have been charged with the responsibility of ensuring that the Board and Senior Management Diversity Policy, and any targets established thereunder, are implemented and that the effectiveness of such policy is assessed regularly and no less than once per year. Under the Board and Senior Management Diversity Policy management is required to report to the Governance and Sustainability Committee and to the Board at least annually on the programs and processes that have been implemented by the Corporation for the purpose of advancing women in senior management roles and the progress achieved under those programs and processes.

The Board has not set any specific targets for representation of Aboriginal persons, persons with disabilities or members of visible minorities on the Board or in senior management positions at this time, nor does it presently, to its knowledge, have any persons within such designated groups on its Board or in senior management positions. The Board has determined that it is not of sufficient size to make such targets practical within a reasonable timeframe and does not wish to set such a long timeframe as to make the targets meaningless. The Board and Governance and Sustainability Committee does give consideration to such factors, however, and will periodically reassess the issue of specific targets.

Diversity of perspectives and viewpoints at the executive level is equally as important as at the Board level and, accordingly, the Board will also consider the diversity criteria set out in the Board and Senior Management Diversity Policy when identifying and selecting candidates for appointment to Executive Officer positions.

5.6

Independence

The Board will be comprised of a majority of independent directors. Each member of the Audit & Risk Committee, the Governance and Sustainability Committee and the Human Resources and Compensation Committee must be an independent director. The majority of the members of the Operations Committee must be independent.

The Board has determined that an independent director is a director who is not a member of management and who does not have a relationship with the Corporation or with management that may affect or be perceived to affect, the director’s ability to act in the best interests of the Corporation. A director is not independent if he or she does not satisfy the independence requirements contained in any applicable securities legislation or regulation or in the rules or policies of any applicable regulator or stock exchange on which the Corporation’s securities are listed for trading. The Board may adopt other categorical standards for determining whether a director is independent and will review the independence of each of the non-management directors annually.

The CEO of the Corporation may serve as a director of the Corporation and, if appointed to the Board, will be the only management director. The CEO may not, however, serve as chair.

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

In the event the Chair is considered non-independent for any reason, the Board will appoint an independent director (the “Lead Director”) to act as the effective leader of the Board, to ensure that the Board’s agenda will enable the Board to successfully carry out its duties and to facilitate the Board’s exercise of independent judgment in carrying out its duties. The position description for the Lead Director is set out in Appendix D.

The Board has adopted a policy of meeting in camera, with only independent directors present, at each regularly scheduled Board meeting. In camera sessions are of no fixed duration and participating directors are encouraged to raise and discuss any issues of concern.

Directors are expected to speak and act independently, respecting differing views held by other directors and management.

5.7

Majority Voting

Election of directors at any meeting of the shareholders of the Corporation where directors are to be elected will take place in accordance with all applicable regulatory and exchange requirements, including the majority voting requirements set out in the Canada Business Corporations Act and the regulations thereunder (collectively, the “CBCA”), and for any such meeting the following majority voting provisions shall apply:

•

A separate vote of shareholders shall be taken with respect to each candidate nominated for director.

•

Shareholders shall be entitled to vote “for” or “against” each candidate nominated for director.

•

Each candidate nominated for director shall be elected only if the number of votes cast “for” that person represents a majority of the votes collectively cast “for” and “against” that person by the shareholders who are present in person or represented by proxy.

The Chair will ensure that the number of shares voted “for” and “against” each nominee is recorded and promptly made public after the meeting by way of press release.

In the event a candidate nominated for director is not elected, subject to any restrictions or requirements contained in applicable corporate law or in the Corporation’s constating documents, the Board may, in its discretion: (a) leave any resulting vacancy on the board unfilled until the next annual meeting; (b) fill the vacancy by appointing a replacement director whom the Board considers merits the confidence of the shareholders; or (c) call a special meeting of shareholders to consider a new nominee to fill the vacant position.

An incumbent director who was a candidate in an election of directors and was not elected will continue as a director until the earlier of: (a) that director’s resignation; (b) the ninetieth (90^th) calendar day after the day of the election; or (c) the day upon which that director’s successor is appointed or elected. Such director is not eligible to be appointed by the Board, however, unless such appointment:

•

is required in order to satisfy the CBCA’s Canadian residency requirement; or

•

is required to satisfy the CBCA’s requirement that at least two directors of a distributing corporation not also be officers or employees of the corporation or its affiliates.

In the event of any conflict between the above and the CBCA or any other regulatory or exchange requirements, the provisions of the CBCA or the applicable regulatory or exchange requirements shall govern, as the case may be.

5.8

Interlocks

An interlock occurs when two or more directors of the Corporation are members on the same board of directors of another public company. No more than two directors may sit on the same public company board without the prior consent of the Board. In considering whether or not to permit more than two directors to serve on the same board, the Board must take into account all relevant considerations including, in particular, the total number of Board interlocks at that time. Also, none of the members of the Audit & Risk Committee may serve on more than three public company audit committees without Board approval.

5.9

Strategic Planning

Management is responsible for the development of the Corporation’s strategic direction and plan. It is the role of the Board to review, question, contribute and approve the strategic plan of the Corporation and to oversee its execution. The Board will review, discuss and approve the Corporations’ strategic plan on an annual basis as well as receiving periodic updates from the CEO on progress.

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

5.10

Oversight of Risks

The Board in discharging its oversight responsibilities, must satisfy itself that the risk management policies and procedures designed and implemented by the Corporation’s senior management are consistent with the Corporation’s strategy and risk appetite. The Board must insist on the implementation of appropriate systems to manage the Corporation’s principal risks, including the implementation of appropriate internal controls and management information systems. The Board must also foster an enterprise-wide culture that supports appropriate risk awareness, behaviors and judgments, as well as one that recognizes and addresses risk-taking beyond the Corporation’s determined risk appetite.

5.11

Ethics and Conflicts of Interest

The Board is responsible for fostering a culture of integrity within the Corporation and in fulfilling that responsibility will:

(a)

satisfy itself as to the integrity of the Executive Officers and that the Executive Officers create a culture of integrity throughout the organization;

(b)

approve and adopt a Code of Conduct and Ethics Policy applicable to directors, officers and employees of the Corporation and periodically review the same to ensure conformance with evolving best practices for corporate governance;

(c)

monitor compliance with the Code of Conduct and Ethics Policy, address and respond to any material departures from the same by any director or Executive Officer that come to the attention of the Board, consider any request for a waiver from the provisions of the same for the benefit of any director or Executive Officer and grant any such waiver if determined by the Board to be appropriate and in the best interests of the Corporation; and

(d)

promote that, in conducting their own business, directors should not place themselves in a position of conflict with the Corporation.

A director has a conflict if he or she is:

(a)

a party to a material contract or transaction or proposed material contract or transaction with the Corporation;

(b)

a director or officer of any entity which is a party to a material contract or transaction or proposed material contract or transaction with the Corporation; or

(c)

a person who has a material interest in any entity which is a party to a material contract or transaction or proposed material contract or transaction with the Corporation.

Immediately upon becoming aware of an actual or potential conflict of interest a director shall inform the Chair as well as the Lead Director if a Lead Director has been appointed. The director shall also advise the CEO and the corporate secretary of the conflict.

Because it may be impractical for a director who serves as a director or officer of another entity or who has a material interest in another entity to know that the entity is entering into a material contract or transaction with the Corporation (and therefore to give notice of every such material contract or transaction), it is sufficient for the director to deliver a general notice to the Board declaring that he or she is a director or officer or has a material interest in an entity and is to be regarded as interested in any material contract or transaction made with that entity. To minimize the possibility of a conflict of interest not being identified, directors will provide to the Corporation and update annually, a list of all shares and options held in the Corporation and all other director positions held in other organizations. Any director owning more than 10% of the outstanding shares of any company or other organization should disclose this ownership to the Corporation’s corporate Secretary.

5.12

Director Compensation

The Board will compensate directors in a form and amount that is fair and appropriate for the services they perform and which is customary for comparable companies, having regard to such matters as time commitment, responsibility and trends in director compensation.

The Board, based upon recommendations of the Compensation Committee, will periodically review the adequacy and form of directors’ compensation, including compensation of the Chair, the Lead Director and the

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

Committee Chairs, to ensure that it is competitive and realistically reflects the responsibilities and risks involved in being a director.

To more closely align the interests of directors and the Corporation’s shareholders, a portion of the directors’ fees may be paid in the form of equity, which may be in the form of deferred share units or other stock-based compensation. In addition, directors are encouraged to hold shares of the Corporation for their own accounts.

A management director will not receive additional compensation for Board service.

5.13

Shareholding Guidelines

The following officers and directors are required to hold the following shares or share equivalent units:

(a)

CEO – Five (5) times annual base salary;

(b)

Executive Officers other than CEO – Three (3) times annual base salary;

(c)

Vice-Presidents – One (1) time annual base salary; and

(d)

Directors – Three (3) times fixed annual retainer, including any lead director retainer but excluding committee chair retainers.

The following requirements shall apply to such holdings:

(a)

the holding requirement shall be a set dollar figure, to be achieved within 5 years of the date such person becomes an officer or director within one of the above categories;

(b)

the value of shares or share equivalent units held at any given time shall be determined as the greater of market or book value of those holdings;

(c)

shares owned for purposes of measuring compliance include actual shares owned (including shares beneficially owned or owned by a spouse) plus share equivalent units (such as DSUs and RSUs, but not including PSUs);

(d)

where a person holds more than one of the positions set out above, the higher applicable ownership requirement shall apply;

(e)

Board members who have not met the holding requirement must take at least 60% of their retainer in DSUs or until such time as the holding requirement is met; and

(f)

As long as a Board member meets the holding requirement, there is no obligation to take any further retainer as DSUs, though the Board member may elect do so (provided that the DSU election may only be changed once per year as per the DSU policy).

5.14

Orientation and Education for Directors

The Board, in conjunction with management, will provide an orientation program for new directors. The Board will ensure that all new directors understand the role of the Board and its Committees. Each director will be provided with a copy of all of the corporate governance policies and charters. Management will conduct orientation sessions with new directors to review the Corporation’s business, issues, risks and opportunities. New directors will also be given the opportunity to tour various operating facilities of the Corporation.

The Board, in conjunction with management, will provide continuing education opportunities for all directors so that individuals may maintain or enhance their skills and abilities as directors on an ongoing basis. Management will provide directors with opportunities to increase their knowledge and understanding of the Corporation’s business and to ensure their understanding of the Corporation’s business remains current.

5.15

Executive Team

The Board, at the recommendation of the Human Resources and Compensation Committee, will appoint the Executive Officers of the Corporation and will monitor their performance against a set of mutually agreed corporate objectives directed at maximizing shareholder value. The Board, at the recommendation of the Human Resources and Compensation Committee, will ensure that Executive Officers receive training and education as determined by the Board to be appropriate to ensure their ongoing professional development and improvement.

The Board expects management succession planning to be an ongoing activity to be reviewed and approved by the Board. This planning process will include, on a continuing basis, the CEO’s recommendation of a successor in the event of an unexpected incapacitation of the CEO.

Management Information Circular

April 8, 2026

North American Construction Group Ltd.

5.16

Access to Advisors

The Board and each Committee will have access to independent legal, accounting, financial and other advisors as each deems necessary or appropriate to assist the Board or Committee in the conduct of its respective duties. The engagement of such advisors will be at the expense of the Corporation.

Any individual director who wishes to engage a non-management advisor at the expense of the Corporation to assist on matters involving his or her responsibilities as a director must review the request with and obtain the authorization of the Chair. Authorization of the Lead Director must also be obtained where a Lead Director has been appointed.

5.17

Term Limits

As set out in the by-laws, the election of directors will take place at each annual meeting of shareholders where the terms of all directors then in office shall be deemed to end. If qualified, however, each shall be eligible for re-election. The Board has determined that fixed term limits for directors should not be established. The Board is of the view that such a policy would have the effect of forcing directors off the Board who have developed, over a period of service, considerable insight into the Corporation and who, therefore, can be expected to provide an increasing contribution to the Board. At the same time, the Board recognizes the value of some turnover in Board membership to provide ongoing input of fresh ideas and reviews annually the composition of the Board in light of its strategic direction.

5.18

Evaluation

The Board is responsible to ensure the continued effectiveness of the Board, its Committees and the individual directors and to foster a process of continuing improvement. Each director will periodically participate in a Board and Committee effectiveness assessment as well as an individual assessment by the director’s peers. Board and Committee assessments will consider, among other things, the effectiveness of the Board or Committee in achieving its mandate as set out in this Policy or the relevant Committee charter, as applicable. Individual peer assessments will consider, among other things, the competencies and skills the individual director is expected to bring to the Board, the director responsibilities set out in Appendix A and the applicable position descriptions for any director serving as Board Chair, Lead Director or the chair of any Committee. The Governance and Sustainability Committee is responsible for establishing the process for Board, Committee and individual director assessments.

Introduction

The Corporation is committed to (i) facilitating an orderly and efficient process for holding annual meetings and, when the need arises, special meetings of its shareholders; (ii) ensuring that all shareholders receive adequate advance notice of the director nominations and sufficient information regarding all director nominees; and (iii) allowing shareholders to register an informed vote for directors of the Corporation after having been afforded reasonable time for appropriate deliberation.

The Corporation believes this By-Law is in the best interest of the Corporation, its shareholders and other stakeholders. This By-Law may be subject to annual review at the discretion of the board of directors of the Corporation (the “Board”) and will reflect changes as required by Applicable Securities Laws (as defined below) or stock exchanges policies, or so as to meet industry standards.
