The questions and answers from the Q&A session will be included in the replay posted on Suncor's website following the meeting.

Suncor's decision to continue hosting its annual meeting in a virtual format is supported by ease of attendance for shareholders, removal of venue capacity restrictions and logistical obstacles, ongoing opportunity for shareholder participation in the Q&A session, as well as technological ability and access to virtual meetings.

Subject to certain restrictions required by the *Petro-Canada Public Participation Act* (as described in the AIF under the heading "Description of Capital Structure – Petro-Canada Public Participation Act") which section is incorporated by reference herein, each common share is entitled to one vote. A simple majority of votes (50% plus one vote) cast at the meeting in person (virtually) or by proxy is required to approve all matters to be considered at the meeting.

Q. #### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; What if amendments are made to these matters or if other matters are brought before the meeting?
**A.** If you attend the meeting in person (virtually) and are eligible to vote, you may vote on such matters as you choose. If you have completed and returned a proxy, the common shares represented by proxy will be voted or withheld from voting in accordance with your instructions on any ballot that may be called for and, if you specify a choice with respect to any matter to be acted upon, the common shares will be voted accordingly. The management nominees named in the proxy form will have discretionary authority with respect to amendments or variations to matters identified in the accompanying notice of annual general meeting of shareholders and to other matters that may properly come before the meeting. As of the date of this Circular, our management knows of no such amendment, variation or other matter expected to come before the meeting. If any other matters properly come before the meeting, the management nominees named in the proxy form will vote on them in accordance with their best judgment.

Q. #### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Who is soliciting my proxy?
**A.** The management of Suncor is soliciting your proxy. Solicitation of proxies will be done primarily by mail, supplemented by telephone or other contact, by our employees or Kingsdale. Kingsdale has been retained to provide a broad array of strategic advisory, governance, strategic communications, digital and investor campaign services on a global retainer basis in addition to certain fees accrued during the life of the engagement upon the discretion and direction of Suncor.

Q. #### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; How can I vote?

Meeting Participation, Voting and Proxies: Questions and Answers

If your shares are not registered in your name but are registered in the name of a nominee, please see "How can a non-registered (beneficial) shareholder vote?" and "How can a non-registered (beneficial) shareholder vote at the meeting?" below.

Q. #### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; How can a non-registered (beneficial) shareholder vote?
**A.** If your shares are not registered in your name but are registered in the name of a nominee (usually a bank, trust company, securities broker or other financial institution), your nominee is required to seek your instructions as to how to vote your shares. Your nominee should have provided you with a package of information respecting the meeting, including either a proxy or a voting instruction form. Follow the instructions provided in the proxy or voting instruction form.

Q. #### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; How can a non-registered (beneficial) shareholder vote at the meeting?
**A.** Non-registered (beneficial) shareholders who have not duly appointed themselves as proxyholders will not be able to vote at the meeting but will be able to virtually attend as a guest. This is because Suncor does not have access to all of the names of its non-registered (beneficial) shareholders, and as a result we will have no record of your shareholdings or of your entitlement to vote unless your nominee has appointed you as a proxyholder. If you wish to vote at the meeting, insert your name in the space provided on the proxy or voting instruction form sent to you by your nominee. In doing so, you are instructing your nominee to appoint you as a proxyholder.

### Business of the Meeting

#### Financial Statements
The audited consolidated financial statements of the corporation for the year ended December 31, 2025, together with the notes thereto and the auditor's report thereon will be placed before the meeting. These audited consolidated financial statements form part of our 2025 Annual Report. Copies of the 2025 Annual Report may be obtained from the Corporate Secretary upon request. The 2025 Annual Report is available on Suncor's website at www.suncor.com and has been filed with the Canadian securities regulatory authorities and the U.S. Securities and Exchange Commission (SEC).

#### Election of Directors
**Number of Directors.** Suncor's articles stipulate there shall be not more than fifteen nor fewer than eight directors. The Board is currently composed of eleven directors, with ten non-employee directors, including Russell Girling, Board Chair, and one member of management, Richard M. Kruger, President and Chief Executive Officer (CEO).

In accordance with our by-laws, the Board has determined that ten directors will be elected at the meeting. Following the meeting, and assuming that all proposed nominees for director are elected as contemplated in this Circular, the Board will be composed of nine non-employee directors and Richard M. Kruger, Suncor's President and CEO. The term of office of each director is from the date of the meeting at which he or she is elected or appointed until the close of the next annual meeting of shareholders or until a successor is elected or appointed.

**Voting Details.** Unless directed otherwise, the management nominees named in the form of proxy will vote FOR the election of the nominees whose names appear on pages 9 to 15.

Management does not expect that any of the nominees will be unable to serve as a director but, if that should occur for any reason prior to the meeting, the management designees named in the form of proxy reserve the right to vote for another nominee at their discretion unless the proxy specifies the common shares are to be voted against the election of directors.

**Majority Voting for Directors.** Pursuant to the *Canada Business Corporations Act*, if there is an uncontested election (being an election where only one candidate is nominated for each position available on the board) at a meeting of shareholders at which directors are to be elected, each candidate is elected only if the number of votes cast in favour of their election represents a majority of the votes cast "for" and "against" them by the shareholders who are present in person or represented by proxy, unless the articles of the corporation require a greater number of votes.

Accordingly, any nominee for director who receives an equal or greater number of votes "against" than votes "for" their election as a director at the meeting shall not be elected to the Board.

#### Advisory Vote on Approach to Executive Compensation
The Board believes that shareholders should have the opportunity to fully understand the objectives, philosophy and principles that the Board has used to make executive compensation decisions.

Please carefully review the "Letter to Shareholders" beginning on page [22](#tLTS) and our "Compensation Discussion and Analysis" beginning on page [24](#tCDAA) before voting on this matter. We encourage any shareholder who has comments on our approach to executive compensation to forward these comments to the Chair of the HR&CC c/o the Corporate Secretary, Suncor Energy Inc., P.O. Box 2844, 150 – 6<sup>th</sup> Avenue S.W., Calgary, Alberta, T2P 3E3. The "Compensation Discussion and Analysis" section discusses our compensation philosophy and approach to executive compensation, what our Named Executive Officers are paid and how their level of compensation is determined. This disclosure has been approved by the Board on the recommendation of the HR&CC.

At the meeting, shareholders will have an opportunity to vote on our approach to executive compensation through consideration of the following advisory resolution:

"RESOLVED, on an advisory basis and not to diminish the role and responsibilities of the Board of Directors, that the shareholders accept the approach to executive compensation disclosed in the management proxy circular of Suncor Energy Inc. delivered in connection with its 2026 annual general meeting of shareholders."

Unless directed otherwise, the management nominees named in the form of proxy will vote FOR the advisory resolution approving the approach to executive compensation disclosed in this Circular.

As this is an advisory vote, the results will not be binding upon the Board. However, in considering its approach to executive compensation in the future, the Board will take into account the results of the vote, together with feedback received from shareholders in the course of our engagement activities. If a significant number of shareholders oppose the advisory resolution, the Board will engage with shareholders (especially those who are known to have voted against it) to understand their concerns and will continue to review the company's approach to executive compensation in the context of those concerns. Since instituting a vote on an advisory resolution on our approach to executive compensation in 2011, Suncor has received strong support from shareholders with an average of 93.45% of votes supporting the corporation's recommended vote, including 98.50% of the votes cast in favour of the advisory resolution at the 2025 annual general meeting of shareholders. For additional information concerning the company's shareholder engagement activities, please see "Terms of Reference – Shareholder Engagement" in Schedule C.

#### Shareholder Proposal No. 1
Set forth on page A-1 of Schedule A of this Circular is Shareholder Proposal No. 1 for the corporation to prepare a report detailing the corporation's governance and oversight of its climate-related risks, which has been submitted for consideration at the meeting and the Board's and management's voting recommendations thereon. Unless directed otherwise, the management nominees named in the form of proxy will vote AGAINST Shareholder Proposal No. 1.

#### Other Business
Shareholders will vote on any other business as may properly be brought before the meeting. As of the date of this Circular, management is not aware of any other matters to be brought before the meeting.

### Board of Directors Compensation

#### Philosophy and Approach

---

| |
|:---|
| &nbsp;&nbsp;&nbsp; **Philosophy. Compensation of non-employee directors is intended to:**<br> • deliver an appropriate level of remuneration to enable Suncor to attract highly qualified individuals with the desired competencies, skills and attributes and the capability to meet the demanding responsibilities of Board members; and <br>• provide a significant portion of such remuneration in equity-based pay to closely align non-employee directors' interests with shareholder interests. <br>|
| **Approach.** The Governance Committee reviews Board compensation levels at least biennially to ensure Suncor's program is competitive and takes into account governance and best practice trends. Compensation changes, when required, are recommended by the Governance Committee to the full Board for approval.  |
| &nbsp;&nbsp;&nbsp; Key practices include: <br> • Share Ownership Guidelines – a substantial share ownership requirement of $1,050,000 for non-employee directors and $1,740,000 for the Board Chair demonstrates alignment with shareholder interests. Common shares and DSUs count toward these requirements. <br>• Substantial Equity Component – a minimum of 80% of compensation must be in the form of equity-based pay until share ownership guidelines are met. Directors that meet the guidelines can elect 60%, 80%, or 100% of compensation in equity-based pay. For 2025, 87% of total compensation paid to non-employee directors was equity based. <br>|

---

#### Structure
Suncor's North American energy peers, identified on page 30 (the Suncor Compensation Peers), used for benchmarking Suncor's Board compensation structure are the same companies used for benchmarking senior executive compensation. Suncor's rank, as compared to the Suncor Compensation Peers, in relation to revenue, assets and enterprise value, is also provided on page 30. The following tables display the Board compensation structure for 2025.

Board compensation was last updated in 2024 following an assessment by Willis Towers Watson (WTW), an independent external executive compensation advisor, that covered compensation components, mix and pay level for non-employee directors, including the Board Chair. No changes to Suncor's director compensation program were made following WTW's 2025 assessment.

The following table displays the compensation structure for 2025 for all non-employee directors.

Board of Directors Compensation

#### Equity Based Compensation
**Minimum Allocation to Equity.** Equity based pay promotes greater alignment between directors and shareholders. At least 60% and up to 100% of the retainers and travel fees payable to non-employee directors must be equity based. Until share ownership guidelines are met, the minimum equity component is 80%.

**Deferred Share Units and Common Shares.** Suncor grants DSUs to non-employee directors, which may only be granted in lieu of cash fees on a value-for-value basis. DSUs cannot be redeemed until the director retires from the Board. When redeemed, each DSU is valued at the then current market price of Suncor's common shares. DSUs remain an important component of director compensation, providing long-term alignment with shareholders' interests.

Since 2023, directors have been offered an alternative form of equity-based compensation: shares purchased on the open market. In 2025, Ms. Bedient and Mr. Gladu elected to receive their equity-based pay in the form of common shares purchased on the open market. All other non-employee directors elected to continue to receive equity-based pay in the form of DSUs. Awards of DSUs and the purchase of common shares on the open market occur quarterly.

The value of equity received in DSUs is converted into a number of DSUs using the Market Value (as defined in the Deferred Share Unit Plan (DSU Plan)) based on the trading price, as stipulated in the DSU Plan. The value of equity received in common shares, after required withholdings are deducted, is used to purchase common shares on the open market. The number of shares acquired is dependent on the actual purchase price at the date of acquisition. Dividends paid on common shares acquired as part of Board compensation are used to purchase additional common shares on the open market. In the DSU Plan, dividends are notionally reinvested by crediting additional DSUs to the non-employee directors' DSU account based on the amount of the dividend and the Market Value on the dividend payment date.

**Share Ownership Guidelines.** Share ownership guidelines are one way that non-employee directors demonstrate their commitment to Suncor's long-term success and alignment with shareholder interests. Suncor periodically benchmarks its share ownership guideline levels to ensure they are in line with its peers. For 2025, share ownership guidelines were $1,740,000 for the Board Chair and $1,050,000 for all other non-employee directors. The level of ownership must be attained by each director by the end of the fifth year after election or appointment to the Board or the date an increase in the share ownership guideline is approved.

Suncor common shares and DSUs count toward the share ownership guidelines. For the purpose of determining compliance with share ownership guidelines, shares and DSUs are valued at the higher of the closing price on the TSX on December 31, 2025 and the acquisition cost. Shares purchased on behalf of directors as a component of compensation cannot be sold unless share ownership guidelines have been, and following the sale will continue to be, satisfied.

The following table provides the aggregate equity holdings of non-employee directors as at December 31, 2025. As at December 31, 2025, all non-employee directors, including the Board Chair, have met or are on track to meet the share ownership guidelines.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Ms. Kneale joined the Board effective February 3, 2026. Therefore, she is not included as part of the disclosures related to director compensation for 2025.

Common shares are valued at the purchase price paid on the respective exchange (TSX: $56.04, $51.66, $59.39, $60.87 CAD; NYSE: $39.01, $37.84, $42.62, $44.48 USD).

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Ms. Kneale joined the Board effective February 3, 2026. Therefore, she is not included as part of the disclosures related to director compensation for 2025.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Share-based awards consist of DSUs and/or common shares purchased on the open market that are awarded in quarterly installments. The number of DSUs or common shares credited to each non-employee director's account on each payment date is equal to one-quarter of the applicable retainer. Grant date fair market value for DSUs is calculated based on the common share price high and low average for the five trading days on the TSX immediately preceding the date of the quarterly award ($55.12, $52.68, $59.12 and $59.18, respectively). Common shares are valued at the purchase price paid on the respective exchange (TSX: $56.04, $51.66, $59.39, $60.87 CAD; NYSE: $39.01, $37.84, $42.62, $44.48 USD).

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Consists of DSUs issued under the DSU Plan including additional DSUs credited in respect of notional dividend reinvestment. DSUs vest immediately upon grant. As a result, all DSUs held by non-employee directors have vested but cannot be redeemed until they cease to hold office. The value is calculated based on the closing price on the TSX of a common share on December 31, 2025 ($60.92).

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Romasko resigned from the Board due to medical reasons effective August 8, 2025. The value shown is as at August 7, 2025 using the closing price on the TSX of a common share on that date ($53.62).

**Redemption of DSUs.** DSUs may be redeemed only when a non-employee director ceases to hold office, on a date elected by that director prior to November 30 of the calendar year following such cessation. For directors subject to payment of U.S. federal tax, the redemption period to elect payout of the DSUs they hold commences on the first day of the calendar year following the year in which the non-employee director ceases to be a member of the Board, and ends on November 30 of that same year. However, no redemption will be permitted within the first six months following separation from service by a U.S. taxpayer who is considered a "specified employee." The cash payment at redemption is calculated by multiplying the number of DSUs by the then-current market value of a common share on the TSX, as per the terms of the DSU Plan.

**Director Hedging Prohibition.** Pursuant to Suncor's policies, directors are not permitted to engage in short selling in Suncor common shares or to purchase financial instruments (including, for greater certainty, puts, options, calls, prepaid variable forward contracts, equity swaps, collars or units of exchange-traded funds) that are designed to hedge or offset a change in the market value of Suncor common shares, DSUs or other securities of Suncor held by the director.

### Executive Compensation

#### Letter to Shareholders
To Our Fellow Shareholders:

On behalf of the HR&CC and the Board, we are pleased to share the company's approach to senior executive compensation and how it aligns with company performance. Specifically, in determining compensation for the President and CEO, the Board of Directors considered company performance across key focus areas outlined below.

**Company Performance.** Suncor achieved exceptional performance in 2025, further building on the momentum of 2024 and 2023. Led by Rich Kruger, Suncor's President and CEO, Suncor delivered record-breaking results in 2025 on safety and operations, including record upstream production, refining throughput, and refined product sales. Remarkably, the company met its 2024 Investor Day commitments a full year ahead of schedule, underscoring its focus, disciplined execution, and leadership.

**Safety.** Ensuring the continued safety of our workforce is our top priority.

✓ Our 0.02 lost time injury frequency is Suncor's ***best-ever*** performance, with injuries down 42% year over year.

✓ Our 0.28 recordable injury frequency is Suncor's ***best-ever*** performance, with injuries down 15% year over year.

✓ Our 0.09 process safety event rate is Suncor's ***best-ever*** performance and represents a 31% year over year decrease.

**Operational Reliability.** Record-breaking results in both our upstream and downstream businesses.

✓ ***Record*** annual production of 860,000 barrels per day (bbls/d), 35,000 bbls/d above the midpoint of our initial 2025 guidance. Supported by ***record*** annual production at Fort Hills of 175,000 bbls/d and ***record*** annual production at Firebag of 245,000 bbls/d.

✓ ***Record*** annual upgrader utilization of 99%. Supported by annual utilization at Base Plant of 98% and ***record*** annual utilization at Syncrude of 100%.

✓ ***Record*** annual refining throughput of 480,000 bbls/d, 38,000 bbls/d above the midpoint of our initial 2025 guidance.

✓ ***Record*** annual refining utilization of 103%. Supported by ***record*** annual utilization at Montreal of 109% and ***record*** annual utilization at Sarnia of 105%.

✓ ***Record*** annual refined product sales of 623,000 bbls/d, 53,000 bbls/d above the midpoint of our initial 2025 guidance.

**Financial.** Our outstanding operational reliability drove equally strong financial performance.

✓ Adjusted funds from operations<sup>(1)</sup> of $12.8 billion and $6.9 billion in free funds flow<sup>(1)</sup>.

✓ Expenses<sup>(2)</sup> of $13.2 billion is within 1.5% of 2024 despite significantly higher volumes and inflation.

✓ Returned $5.8 billion to shareholders: increased the quarterly dividend paid per share by 5% from 2024, totaling $2.8 billion and repurchased $3.0 billion in shares, or 4.4% of shares outstanding as at December 31, 2025.

**Investor Day Commitments.** We delivered our commitments one year early.

✓ Increased normalized free funds flow<sup>(1)</sup> by over $3.3 billion per year versus 2023.

✓ Reduced corporate WTI breakeven by over US$10 per barrel versus 2023.

✓ Increased upstream production by 114,000 bbls/d versus 2023.

✓ Reduced annual capital expenditures to $5.7 billion.

✓ Maintained net debt<sup>(1)</sup> below target of $8 billion (achieved in 2024) and continued returning 100% of excess funds to shareholders.

Suncor's significant improvements through 2025 under Mr. Kruger's leadership were recognized in Suncor's share price appreciation of 19% in 2025, outperforming the average of Suncor's Performance Share Units peers by 14%.

#### Compensation Outcomes.
The Board chose to maintain Mr. Kruger's salary at $1,350,000, awarded an annual incentive payment of $3,908,250 which is above the target value due to the company's exceptional 2025 performance and granted an annual equity award of $10,125,000.

Compared to our peers, Mr. Kruger's target total direct compensation remains within a reasonable range around the median of our North American peer group when converting US-dollar pay at par and at recent market exchange rates.

Executive Compensation

#### Compensation Governance
**Board of Directors.** The Board oversees development of the overall strategic direction and policy framework for Suncor. This responsibility, in part, is discharged with the assistance of Board committees, including the HR&CC. Further details relating to Board committees can be found in Schedule C.

**Human Resources & Compensation Committee.** Central to the role of the HR&CC is aligning executive compensation with the delivery of shareholder value. The role and operation of the HR&CC under its mandate includes assisting the Board annually in the areas of executive compensation, succession planning, incentive compensation plans and compensation governance. Key objectives in these areas include:

• reviewing and approving the overall corporate goals and objectives of Suncor relevant to compensation of the CEO, and ensuring that they are supported by an appropriate executive compensation philosophy and program;

• overseeing and approving incentive plan design and outcomes;

• evaluating the performance of the CEO against approved goals and objectives, and recommending to the Board the total compensation for the CEO in light of that performance;

• reviewing the CEO's evaluation of the other senior executives' performance;

• approving total compensation of senior executives other than the CEO;

• reviewing the succession planning process and results for senior executive roles;

• reviewing NEO and other senior executive termination agreements and NEO termination obligations in relation to market practices and trends;

• reviewing compensation programs using a risk assessment framework to help ensure Suncor's compensation programs and practices do not encourage the taking of excessive or inappropriate risks;

• reviewing, on a summary basis, any significant compensation, pension and benefit programs for employees generally, with consideration of accounting, tax, legal, regulatory, governance, cost and risk implications and the pay-for-performance relationship for variable pay;

• overseeing management of the impact of workforce changes and the impact to culture alignment and plans and processes for promoting equity, inclusion and diversity; and

• reviewing and recommending executive compensation disclosure to the Board for approval before Suncor publicly discloses this information.

The HR&CC fulfilled its mandate, as summarized in this section, in 2025.

All HR&CC members are independent directors. The HR&CC is currently comprised of the following members: Brian MacDonald (Chair), Ian R. Ashby, Jean Paul (JP) Gladu, Christopher R. Seasons, and M. Jacqueline Sheppard.

The HR&CC members have experience in leadership roles involving environment, health and safety and social performance, strong knowledge of the energy industry (all five with an energy industry background), a mix of functional experience and competency, and tenure as directors of various public companies. This background provides the HR&CC with the collective experience, skills and qualities to effectively support the Board in carrying out its mandate. Further information on HR&CC member experience and skills is provided in the inventory of Board member experience and competencies on page C-3 of Schedule C.

**Executive Compensation Consultants.** Since 2024, the HR&CC has engaged WTW as its independent external executive compensation advisor. Prior to the appointment of WTW, the HR&CC's executive compensation support was provided by both WTW and Meridian Compensation Partners through July 2024.

WTW provided consulting support and information in the following areas:

• expertise and advice in the development of compensation policies and programs for executives and the Board;

• provided updates on best practices, trends and emerging regulatory or governance matters related to executive compensation;

• benchmarking Suncor compensation in the marketplace; and

• support in conducting an annual risk assessment of Suncor's compensation policies and programs.

The decisions made by the HR&CC may reflect factors and considerations other than as provided or recommended by our executive compensation consultant. During 2025, WTW met with the HR&CC Chair and attended relevant sections of HR&CC meetings as necessary. WTW attended in-camera sessions of the HR&CC as requested.

**25 Management Proxy Circular 2026** Suncor Energy Inc.

[**TABLE OF CONTENTS**](#TOC2)

WTW also supports management in the area of executive compensation and provides services in other human resources areas, including pensions and benefits. WTW has protocols in place to ensure that they are in a position to provide independent advice. WTW was originally retained by Suncor in February 2006.

The HR&CC verified WTW's independence in 2025 based on the following:

• WTW works on behalf of the enterprise with conclusions and recommendations shaped by what is appropriate for Suncor;

• members of the executive compensation consulting team are not responsible for selling other services to Suncor and receive no incentive or other compensation based on the fees charged to Suncor for other services provided. The executive compensation consulting team is separate and distinct from the teams that assist Suncor management with other services provided;

• the executive compensation consultants do not have a business or personal relationship with any of the committee members or management, and do not own Suncor shares other than possibly through mutual funds; and

• WTW has strict protocols and processes to mitigate conflicts of interest, and all consultants are required to adhere to a code of conduct.

 *Executive Compensation-Related Fees* 

Executive compensation-related fees paid by Suncor in 2025 and 2024 to WTW are displayed in the following table:

---

| | | |
|:---|:---|:---|
| Executive Compensation Consultant  | Fees Paid <br> Related <br> to 2025 <br> ($)  | Fees Paid <br> related <br> to 2024 <br> ($)  |
| WTW | 391 000 | 295 000 |
| Meridian Compensation Partners |  | 51 508 |

---

 *All Other Fees* 

WTW's Human Capital and Benefits practice has also assisted in certain matters related to pension and benefits, including, but not limited to, actuarial and accounting services. Total fees payable to WTW for the foregoing services were $2.4 million in 2025 and $1.9 million in 2024. Note that the above amounts exclude WTW services related to the Syncrude joint venture and its legacy retirement programs, which were $1.9 million in 2025 and $3.0 million in 2024.

The HR&CC pre-approves all material executive compensation-related fees paid. The HR&CC does not approve services provided by WTW that do not relate to executive compensation-related services.

#### Pay and Performance Overview
**Pay Programs Are Supported by Key Governance Practices.** Suncor has implemented and maintains a number of key executive compensation governance practices that we believe are consistent with best practices, support our business objectives and align with shareholder interests.

**Managing Compensation Risk.** Suncor's executive compensation policies and programs are designed to create appropriate incentives to increase long-term shareholder value. While the energy business by its nature requires some level of risk taking, Suncor maintains an effective combination of oversight procedures and compensation program risk mitigating features, including plan designs, policies, guidelines, and governance practices, that limit the potential for programs to encourage unacceptable and excessive risk taking. Key oversight procedures and risk mitigating features to support managing compensation risk are outlined below.

#### Oversight Procedures

---

| |
|:---|
| &nbsp;&nbsp; • Strategic Planning: Board-reviewed plans balance risk and reward across company and industry contexts. <br>|
| &nbsp;&nbsp; • Risk Management Tools: Enterprise Risk Management, Operational Excellence, and Trading Risk policies guide risk identification and control. <br>|
| &nbsp;&nbsp; • Financial Controls: Limits on capital, operating spend, divestitures, and trading reduce exposure to inappropriate risk. <br>|
| &nbsp;&nbsp; • Compensation Risk Assessment: HR&CC annually evaluates pay structure, plan design, performance metrics, and governance to ensure programs do not encourage excessive risk. <br>|
| &nbsp;&nbsp; • 2025 Review Outcome: HR&CC confirmed compensation policies do not encourage excessive risk-taking and do not pose material risk to Suncor. <br>|

---

#### Key Risk Mitigating Features

---

| |
|:---|
| Balanced pay structure  |
| &nbsp;&nbsp; • Suncor's executive compensation balances fixed and variable pay elements. <br>|
| &nbsp;&nbsp; • Annual Incentive Plan (AIP): Based on a balanced scorecard of financial and operational metrics; stress-tested and reviewed by HR&CC. <br>|
| &nbsp;&nbsp; • Stock Options: Reinforcing long-term shareholder alignment with a 7-year term. <br>|
| &nbsp;&nbsp; • Market PSUs: Tied to 3-year relative total shareholder return (TSR) and ROCE; payouts range from 0-200% based on performance quartiles. <br>|
| &nbsp;&nbsp; • Climate PSUs: Introduced in 2022; focus on Suncor's climate objectives. <br>|
| &nbsp;&nbsp; • RSUs: Provide stable retention value and align with TSR. <br>|
| &nbsp;&nbsp; • DSUs: Executives may defer AIP payment into DSUs to meet share ownership guidelines. <br>|

---

---

| |
|:---|
| Policies and Guidelines  |
| &nbsp;&nbsp; • Share ownership guidelines enforced, including post-retirement for the CEO. <br>|
| &nbsp;&nbsp; • Clawback policy aligned to comply with Rule 10D-1 of the Exchange Act and related rules of the New York Stock Exchange (NYSE). <br>|
| &nbsp;&nbsp; • Executives prohibited from hedging or short-selling Suncor shares. <br>|
| &nbsp;&nbsp; • HR&CC retains discretion to adjust payouts based on performance and events. <br>|

---

**Executive Hedging Prohibition.** Pursuant to Suncor's policies, executives are not permitted to hedge Suncor shares or equity awards and may not engage in short selling in Suncor shares or to purchase financial instruments (including, for greater certainty, puts, options, calls, prepaid variable forward contracts, equity swaps, collars or units of exchange-traded funds) that are designed to hedge or offset a change in the market value of Suncor's common shares or other Suncor securities held by an executive.

**Executive Share Ownership Guidelines.** Suncor strongly believes that executives' interests should be aligned with the interests of Suncor's shareholders. One of the key ways we reinforce this is by requiring executives to own Suncor common shares or share equivalents equal to a multiple of their annual base salary.

The share ownership guideline level must be achieved by the end of the fifth year after appointment to an executive position or promotion to a more senior executive position.

**27 Management Proxy Circular 2026** Suncor Energy Inc.

------

[**TABLE OF CONTENTS**](#TOC2)

Suncor common shares and DSUs count toward fulfillment of the share ownership guidelines. Beginning in 2025, unvested RSUs are also counted, provided that at least 25% of the ownership requirement is held in common shares and DSUs. Where share ownership guidelines have not been met within the prescribed period, executives must use the cash payout from their annual incentive award, a current vested RSU or PSU grant payout, or other cash resources to immediately satisfy any shortfall to the current share ownership guideline for their level. For the purpose of determining compliance with share ownership guidelines, shares, unvested RSUs and DSUs are valued at the higher of the closing price on the TSX on December 31, 2025 and the acquisition cost.

**CEO Hold Requirement.** Suncor requires its CEO to maintain their share ownership level for one year following retirement, which aligns with current good governance practices and shareholder interests.

**Compliance with 2025 Guidelines and Total Value at Risk.** The following table sets forth the compliance of each NEO with the share ownership guidelines as a multiple of annual salary as at December 31, 2025. All NEOs are in compliance with their current share ownership guideline.

Vested PSUs and RSUs, including those that vested on December 31, 2025, are excluded. This value is not used to evaluate Share Ownership Guideline compliance, and instead reflects the total value of shares and equity-based pay that fluctuates with the price of common shares.

**Compensation Decision-Making.** The HR&CC maintains a structured annual decision-making process that involves management, the HR&CC and the Board to ensure compensation aligns with shareholder interests, rewards executives for performance achieved and enables Suncor to attract and retain talented executives. The steps below illustrate the performance and compensation planning process, which also includes consideration of market information, governance practices, trends and advice from our executive compensation consultants.

*Step 1*: Review pay philosophy, peer group and program design. Benchmark compensation levels and assess trends. Determine pay mix, pay at risk and establish compensation for the upcoming year.

*Step 2*: Review and approve corporate and business unit goals and metrics and CEO individual goals. Review and approve annual and longer-term compensation program results. Review disclosure of prior year compensation decisions and program results.

*Step 3*: Monitor company progress and evaluate in-year performance under compensation programs.

*Step 4*: Evaluate company and CEO performance and determine compensation that will be recommended to the Board. Review and approve compensation for other senior executives.

#### Approach to Executive Compensation
**Total Direct Compensation Components.** Total direct compensation, made up of base salary, an annual incentive and mid- to long-term incentives, is designed to reward short-term results and achievement of sustained longer-term performance in key business areas that enable the operational and financial results that are important to our shareholders.

**Defining Our Marketplace.** As Canada's largest integrated energy company and the third largest in North America by enterprise value as at December 31, 2025, size and business scope are key criteria in defining the marketplace and peer companies used to establish competitive compensation levels for our executives.

To ensure competitive compensation, our HR&CC-approved peer group is comprised of 15 North American companies of comparable size and complexity, and which are representative of our market for executive talent. The same peer group is used to benchmark Board compensation. In Canada, we include oil & gas companies, pipeline companies and other relevant companies in capital intensive industries, while in the U.S., we limit peers to energy companies with similar operations.

Senior executive total direct pay is targeted at the median of the Suncor Compensation Peers, which are identified below, with the flexibility to position pay where needed based on consideration of:

• Individual experience, expertise, and contributions

• Our relative size as we are larger than most of the Suncor Compensation Peers

• Currency considerations arising from our North American market for talent

The peer group used to determine executive compensation for 2025 was updated to reflect recent market activity. Marathon Oil and Hess Corporation were included in the 2024 peer group and removed in 2025 due to acquisitions. To maintain the relevance and comparability of the peer group, Phillips 66 and Valero Energy Corporation were added as replacements for the 2025 peer group.

Executive Compensation

Suncor also maintains a similar performance peer group that is used to determine relative TSR performance for our PSU grants as described on page 33. Differences from the Suncor Compensation Peers reflect the specific purpose of each group (i.e., benchmarking of executive pay versus comparing company shareholder return performance).

#### Compensation of the Named Executive Officers
**2025 Total Direct Compensation.** The 2025 base salary, annual incentive and long-term incentive awards for each NEO are described in the tables that follow in this section.

**Base Salary.** During 2025, NEO base salaries were increased by the percentages displayed in the following table. The increases reflect their demonstrated capabilities and ensure that their base salaries are competitive with the market for their positions.

**Annual Incentive Plan (AIP).** The Annual Incentive Plan supports a common view of our safety / environment, reliability and financial performance through the use of a single company-wide scorecard with eight metrics in three equally weighted categories with a maximum payout of 200% target. A minimum AFFO threshold must be achieved before any payout can be made under the AIP. This ensures overall program affordability.

---

All NEOs and select other senior executives receive an overall score based on Suncor's performance, which are approved by the Board. Other salaried employees have an additional individual performance component.

**Overall AIP score for 2025.** The weighting in AIP and overall score approved for the three categories of eight performance metrics are summarized below.

Governance of the AIP is comprehensive. Reviews of performance measures, weightings, targets and results are carried out at the business unit, corporate and HR&CC level. The HR&CC has discretion to increase or decrease awards under the AIP based on its assessment of the impact of events that may have had an effect on performance. In 2025, the HR&CC did not exercise its discretion over the AIP outcome.

**Long-Term Incentive (LTI) Plan.** Suncor's business involves strategic investments over long periods of time. With stock options, PSUs, CPSUs and RSUs as key elements of long-term incentive (LTI) compensation, the compensation of the NEOs is aligned with the economic interests of our shareholders over a medium- and long-term horizon and is significantly leveraged to Suncor's share price performance from an actual, realized compensation standpoint. Under this approach to executive compensation, our NEOs are rewarded based on a balance between performance on relative TSR (PSUs), ROCE (PSUs), achievement of climate goals (CPSUs) and absolute share price (PSUs, RSUs and stock options).

The following table provides the key LTI plan features for equity awards provided to the NEOs and other executives as part of their competitive compensation in 2025. Effective for 2026 LTI awards, the HR&CC approved an adjustment to LTI vehicle weightings to ensure continued alignment with peers, Suncor's strategy and compensation philosophy.

#### Performance Peer Group: Relative TSR
Peer companies are selected based on size (revenue and enterprise value), industry scope, common peer usage, and share price dynamics. Criteria are reviewed periodically and approved by the HR&CC. Performance peers are reassessed annually for new grants.

To strengthen Suncor's position as Canada's leading energy provider, the HR&CC triple-weighted Canadian peers, resulting in a peer group of 17 companies – approximately 50% of which are Canadian.

For additional details please refer to the "Summary Compensation Table."

#### 2025 Total Direct Compensation
Mr. Kruger did not receive an increase in base salary in 2025, his salary remained at $1,350,000. The AIP award of $3,908,250 represents 193% of his target opportunity and is based on Suncor's performance. Mr. Kruger's long-term incentive grant value was $10,125,087, in the form of stock options, PSUs and RSUs, as indicated in the chart below. The actual value of the award will vary depending on Suncor's future share price and TSR performance relative to Suncor's peers. Mr. Kruger's 2025 compensation is within a reasonable range around the median of our North American peer group when converting US-dollar pay at par and at recent market exchange rates.

In 2023, at the time Mr. Kruger was hired, the value of deferred compensation that Mr. Kruger forfeited by joining Suncor was replaced with Suncor RSUs that vest over one-, two- and three-years. The total value of these "make whole" awards of $23.1 million was a direct replacement of the value that Mr. Kruger would have received if he had remained retired. These awards ensured a responsibly competitive compensation opportunity tailored to the specific circumstances required to successfully recruit Mr. Kruger to lead Suncor. The value he realizes will depend on Suncor's share price when these awards vest and the value of accrued dividends. Additionally, an award of $2.3 million worth of DSUs was provided in lieu of any form of pension or savings plan contributions. These DSUs can only be redeemed after he retires from Suncor.

Executive Compensation

#### Executive Compensation Alignment with Shareholder Value
In an industry subject to commodity price cycles, Suncor continues to focus on long-term value growth and returns for shareholders. The following performance graph shows Suncor's cumulative TSR for the past five years against equity market benchmarks as well as total direct compensation pay opportunity of the NEOs. The total direct compensation of the NEOs has been generally consistent with TSR, as a substantial portion of NEO total direct compensation is linked to Suncor's share price and therefore is aligned with the interests of shareholders.

**Pay Alignment to Total Shareholder Return.** In reviewing alignment of our pay programs with performance we look at two different perspectives: pay opportunity (as reported annually in the Summary Compensation Table) and realizable pay (pay opportunity, but with equity award values capturing common share prices as at December 31, 2025).

The following charts demonstrate the alignment between Suncor's CEO pay and TSR over the past three years for pay opportunity and realizable pay relative to the chief executive officers of the Suncor Compensation Peers.

Suncor is positioned below the zone of alignment, as 3-year CEO pay opportunity is below the company's TSR (specifically, at the 47<sup>th</sup> percentile for pay opportunity and the 87<sup>th</sup> percentile for TSR). When considering realizable pay, Suncor is positioned within the zone of alignment (specifically, at the 73<sup>rd</sup> percentile for realizable pay and the 87<sup>th</sup> percentile for TSR). This demonstrates the effectiveness of the pay for performance design of Suncor's executive compensation programs.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For share-based awards, the fair value of awards at the grant date reflects the number of PSUs, RSUs or DSUs awarded multiplied by the grant price. We use this methodology for consistency with market practice and with the methodology used in competitive market analysis. The grant price was calculated as the average of the high and low common share prices on the TSX on the five trading days preceding the grant date. DSUs received because of a voluntary election to defer AIP awards that would otherwise have been paid in cash are included under non-equity incentive plan compensation. For the grant prices of share-based awards granted to the NEOs, see Schedule B.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Suncor values its option-based awards using the Black Scholes methodology, which is in accordance with International Financial Reporting Standards, for consistency with the accounting valuation. For option-based awards granted through our compensation cycle, the fair value of the awards at the grant date reflects the number of options awarded multiplied by the accounting fair value. The fair value of 2025 option awards granted was $12.52. The fair value was calculated using the following assumptions: common share weighted average price of $56.58, expected life of 4.4 years, volatility of 35%, risk free rate of 2.7% and dividend yield of 4.1%. In May 2023, Mr. Kruger's on hire option grant was valued at $10.28 per option. In August 2023, Mr. Oldreive's on hire option grant was valued at $12.65 per option. For information on the 2024 and 2023 options, refer to the Summary Compensation Table in Suncor's 2025 and 2024 management proxy circulars, respectively.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Consists solely of awards earned under Suncor's AIP. Awards earned and included under the AIP for 2025 performance were paid in 2026. Similarly, awards earned and included for 2024 and 2023 were paid in the year following the year in which they were earned.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Pension Value reflects the compensatory change, increase (decrease), in the pension obligation as disclosed in the tables under the "Defined Benefit Plans" and the "Defined Contribution Plans" sections on pages 40 and 41, respectively.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For all NEOs, excluding the CEO, All Other Compensation for 2025 includes actual costs incurred by Suncor related to company contributions as part of the Suncor savings plans including the company savings match program. It was mutually agreed that Mr. Smith would retire from his position as Chief Financial Officer on December 31, 2025. It was determined that Mr. Smith would end his employment with Suncor and received a payment of $1 million, which was less than the amount that would have been payable under the termination provisions of Mr. Smith's executive employment agreement. No additional severance, equity acceleration, pension enhancements, or post-retirement consulting arrangements were provided beyond the regular retirement provisions. Each of the active NEOs, excluding Mr. Kruger, receives an annual perquisite allowance in the amount of $30,000. The aggregate amounts of annual perquisites and other personal benefits did not exceed the lesser of $50,000 or 10% of the total annual salary for each NEO, other than Mr. Kruger, and are not included in the All Other Compensation value. Mr. Kruger receives an annual perquisite allowance of $35,000, and the pro-rated amount for 2023 of $26,250 is included in All Other Compensation. In addition to his perquisites in 2025, Mr. Kruger incurred family and personal travel expenses, for company jet use, valued at $23,239, which is reported as a perquisite under All Other Compensation.

(6) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kruger was hired effective April 3, 2023. His 2023 salary and annual incentive are prorated to reflect his start date.

(7) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kruger's on hire compensation included an annual grant of $8,775,080, of which 75% or $6,581,320 is included in Share-Based Awards and the balance reflected under Option-Based Awards. In addition, he was awarded $23,107,667 in RSUs as a direct replacement of the outstanding compensation from a previous employer forfeited as a result of coming out of retirement to lead Suncor. The final component of 2023 Share-Based

Awards is $2,310,758 in DSUs in lieu of participating in any Suncor pension or savings program for his tenure with the company. The DSUs cannot be redeemed until Mr. Kruger ceases employment with Suncor.

(8) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Oldreive was hired effective June 19, 2023. His 2023 salary and annual incentive are prorated to reflect his start date.

(9) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Oldreive's on hire compensation included an annual grant of $2,200,071, of which 75% or $1,650,068 is included in Share-Based Awards and the balance reflected under Option-Based Awards. In addition, he was awarded $1,400,066 in RSUs to replace the value of his outstanding equity from a previous employer that was forfeited and $3,200,012 in DSUs to offset lost pension value, based on third party actuarial advice. The DSUs cannot be redeemed until Mr. Oldreive ceases employment with Suncor.

(10) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Smith's 2023 long-term incentive award considered, among other things, his service as Interim CEO for three months, an expanded scope of accountabilities including IT and supply chain functions within the CFO portfolio, and the effective transfer of institutional knowledge from 23 years with Suncor.

**Share-Based Awards and Option-Based Awards.** The following table provides certain information about option-based awards and share-based awards outstanding for the NEOs as at December 31, 2025. For further details, including the exercise price and expiration date of each option-based award held by the NEOs as at December 31, 2025, see Schedule B.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Value of options is based on the "in-the-money" amount of the exercisable and non-exercisable options held as at December 31, 2025. The "in-the- money" amount is the difference between the closing price of a common share on the TSX as at December 31, 2025 ($60.92) and the exercise price of the option.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Includes RSUs granted under the RSU Plan and PSUs granted under the PSU Plan that were held by the NEOs as at December 31, 2025. Excludes PSUs and RSUs granted in 2023 that vested December 31, 2025.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Value of RSUs and PSUs is calculated based on the actual units, including fractional units, multiplied by the closing price of a common share on the TSX as at December 31, 2025 ($60.92). PSUs are projected to pay out at target. Under the PSU Plan, PSUs may vest between 0% and 200% based on performance at the end of the three-year period. See "Summary of Incentive Plans – Performance Share Unit Plan" for details.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Share-based awards include DSUs granted under the DSU Plan that were held by the NEOs as at December 31, 2025. DSUs cannot be redeemed until the NEO ceases to be an employee of Suncor. Value of DSUs is calculated based on the closing price of a common share on the TSX as at December 31, 2025 ($60.92). This amount also includes PSUs issued in 2023 under the PSU Plan that vested on December 31, 2025 and paid out in February 2026. This amount also includes RSUs issued in 2023 under the RSU Plan that vested on December 31, 2025 and paid out in January 2026. The value of these PSUs and RSUs is based on actual payout.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kruger's on hire compensation included "make whole" RSUs to replace his lost equity valued on his date of hire and DSUs in lieu of participating in any Suncor pension or savings program. The DSUs cannot be redeemed until Mr. Kruger ceases employment with Suncor.

(6) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Oldreive's on hire compensation included "make whole" RSUs to replace his lost equity valued on his date of hire and DSUs to offset lost pension value, based on third party actuarial advice. The DSUs cannot be redeemed until Mr. Oldreive ceases employment with Suncor.

**Suncor Retirement Arrangements.** The Suncor Energy Pension Plan is a registered pension plan that provides retirement income to Suncor employees and former employees, including NEOs but excluding Mr. Kruger. Retirement income is based on a defined contribution account balance, or depending upon the employee's eligibility and election, based on a combination of a defined benefit pension payment, including an employee-paid benefit feature, and a defined contribution account balance. Ms. Powell and Messrs. Little, Oldreive, Smith and Zebedee participate in the combination provision of the plan.

In addition to the pension provided under the Suncor Energy Pension Plan, certain executive officers receive supplemental retirement payments under the terms of the executive pension plans: the SERP or the Supplemental Bonus Pension Plan (SBPP). These are non-registered supplemental retirement arrangements. The SERP was closed to new entrants effective September 1, 2023. Three members of Suncor senior executive management were participants in the SERP as at December 31, 2025. Executive officers not eligible for the SERP participate in the SBPP which mirrors the registered pension plan provisions but provides for additional pension benefits based on the executive's annual incentive target bonus.

The SBPP is designed to support executive attraction and retention. Entry into the SBPP commences at the date of appointment to executive employment. The defined benefit is calculated using credited service from date of entry into the combination provision of the plan and the annualized amount of average salary plus target bonus for the best consecutive 36 months of the last 180 months of continuous service. Defined benefit payments for retirement prior to age 60 will be reduced by 5%/year the executive retires before age 60, with no reduction applied for retirement after age 60. The normal form of payment on

retirement, and the basis on which benefits in the table under "Defined Benefit Plans" are computed is, for married executives, joint and survivor, with 50% to the non-member surviving spouse; and for single executives, for life, with ten years guaranteed.

SERP is a career-based pension that features an up-front accrual. This benefit is balanced by features that limit the executive pension by: (i) requiring that an executive provide five years of service to be entitled to SERP benefits, which is five years more than the service required under the Suncor Energy Pension Plan; (ii) limiting service to Suncor related experience only, both for vesting and benefit accrual purposes; (iii) limiting the executive's total pension to 50%, unless there is total service greater than 25 years, in which case the maximum is 70% of executive remuneration; and (iv) limiting executive remuneration to a maximum of 1.8 times base salary (base salary plus annual incentive target bonus of up to 80% of base salary).

Five years of executive employment including, where applicable, the period of notice of termination or payment in lieu of such notice, are required for rights under the SERP to vest. SERP members with less than five years of executive employment are not eligible to receive supplemental retirement payments under the SERP except in the event of a change of control, or a loss of employment upon or after the occurrence of certain specified events.

Trust arrangements have been established to provide for the long-term funding of Suncor's non-U.S. taxpayer SERP and SBPP defined benefit obligations.

**Defined Benefit Plans.** The following table summarizes the retirement income of each of the NEOs under the defined benefit provisions of Suncor's pension arrangements.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Credited service is service within Suncor's defined benefit pension provisions. For Mr. Smith, credited service reflects executive employment of 14 years plus 11 years of service accrued under the Suncor Energy Pension Plan defined benefit provisions prior to becoming eligible for SERP. Mr. Smith retired effective December 31, 2025. For Ms. Powell, credited service reflects executive employment of 4 years plus 27 years of service accrued under the Suncor Energy Pension Plan defined benefit provisions prior to becoming eligible for SERP. Messrs. Little and Oldreive joined the defined benefit provisions after initial participation in the defined contribution provisions of the Suncor Energy Pension Plan.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Represents the estimated annual pension, excluding any employee paid ancillary benefits and before any applicable early retirement reduction that would be received by the NEO based on actual pensionable service to the stated date and actual executive remuneration as at December 31, 2025.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The defined benefit obligation is the estimated value of the pension obligation to the date indicated using the actuarial assumptions and methods that are consistent with those used in determining the pension obligation as disclosed by Suncor in its consolidated financial statements. See note 22 in Suncor's audited consolidated financial statements for the year ended December 31, 2025. The methods and assumptions used to determine the estimated amounts may not be identical to those used by other companies and as a result may not be directly comparable to the amounts disclosed by other companies.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Compensatory change represents the increase (decrease) in the pension obligation for 2025 related to the annual service cost, compensation changes, including target bonus, higher or lower economic and actuarial assumptions and the impact of plan changes, if any. This amount may fluctuate significantly from year-to-year as changes in compensation impact the pension obligation for all years of credited service.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Non compensatory change includes items such as, but not limited to, interest on the obligation, changes in assumptions for future salary projections and changes to the discount rate.

Executive Compensation

**Defined Contribution Plans.** Under the combination provision of the Suncor Energy Pension Plan, applicable to Ms. Powell and Messrs. Little, Oldreive, Smith and Zebedee, Suncor makes contributions to the defined contribution accounts for all employees of 1.5% of basic earnings, plus up to an additional 3% of basic earnings on a 100% matching basis. All contributions to the defined contribution accounts are subject to maximum levels. Under the Suncor Energy Pension Plan, employees may invest the balance of their accounts in a broad range of investment funds made available by the plan. An employee's investment return is based upon the market returns earned by each fund in which the employee has chosen to invest their contributions. At retirement, employees may transfer the balance of their accounts to a pension account as prescribed by law or the corporation may purchase an annuity on behalf of the employee.

The following table summarizes the defined contribution accounts of each of the NEOs.

### Termination Agreements and Change of Control Arrangements

#### Termination Agreements
Suncor has employment termination agreements with each of the NEOs currently employed by the corporation.

![[MISSING IMAGE: tb_quick-pn.jpg]](tb_quick-pn.jpg)

**Termination Events.** The NEOs may be entitled to incremental and/or accelerated compensation as a result of four triggering events:

A)

Voluntary Retirement. Potential benefits relate to accelerated vesting of stock options, in accordance with the terms and conditions of the SOP applicable to all participants.

B)

Termination by Suncor, other than for just cause.

C)

Termination by Suncor, other than for just cause, in connection with a change of control.

D)

Voluntary termination in connection with a change of control. The only potential benefit is vesting in the SERP.

**A) Retirement.** Mr. Kruger is eligible to voluntarily retire as of December 31, 2025. None of the other NEOs employed by the corporation were eligible to voluntarily retire as of December 31, 2025. Upon retirement, in accordance with the terms and conditions of the SOP, all unvested stock options vest and the expiry date is the earlier of the original expiry date and three years following retirement. Under certain conditions, awards may be pro-rated if the retiree is less than 60 years old.

**B) Termination without cause.** All NEOs are entitled to payments equal to their base salary plus the value of the Annual Incentive Plan over the 24-month notice period. The Annual Incentive value is the lesser of the prior 3-year average annual amount and the current target award.

Mr. Kruger is treated as a retiree under the SOP, the PSU Plan, and the RSU Plan. See above.

Termination agreements with other NEOs provide for a payment equal to the in-the-money value of all unvested stock options that would have vested during the 24-month notice period. Termination agreements pro-rate outstanding PSUs and RSUs for active service during the 36-month performance period or restricted period. PSUs and RSUs continue to vest and mature on the original schedule, and all performance conditions continue to apply.

Participants in the SERP (Ms. Powell and Mr. Zebedee) and SBPP defined benefit participants (Messrs. Little and Oldreive) receive credit for an additional 24 months of executive defined benefit service.

**C) Change of Control + Termination.** All NEOs are entitled to payments equal to their base salary plus the value of the Annual Incentive Plan over the 24-month notice period. The Annual Incentive value is the lesser of the prior 3-year average annual amount and the current target award.

For Mr. Kruger, the provisions of the SOP, the PSU Plan, and the RSU Plan apply. Accordingly, on the termination date all unvested options vest, all outstanding RSUs mature, and all unvested PSUs vest. Payments for PSUs and RSUs are determined in accordance with plan provisions. Performance for PSUs is determined up to the termination date.

Termination agreements with the other NEOs override plan provisions for PSUs and RSUs. Stock options are treated in accordance with provisions of the SOP. Treatment of PSUs and RSUs is the same as termination event B (termination without cause). See above.

Participants in the SERP (Ms. Powell and Mr. Zebedee) receive credit for an additional 24 months of service and are immediately vested, if not already vested. SBPP defined benefit participants (Messrs. Little and Oldreive) receive credit for an additional 24 months of executive defined benefit service.

Executive Compensation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**D) Change of Control + Resignation.** The only potential benefit is immediate vesting in the SERP. No additional service is provided, and no other payments or benefits are accelerated nor are performance conditions waived. As of his retirement effective December 31, 2025, Mr. Smith was already vested in the SERP. Mr. Zebedee and Ms. Powell would immediately vest.

**Governance of Termination Agreements.** The HR&CC annually reviews the status of termination agreements and change of control arrangements for Suncor's senior executives and periodically reviews current governance trends and market practices. Based on the HR&CC's review of governance trends and market practices, amendments may be made to agreement terms for new participants.

In addition to setting out the rights of Suncor and the executive upon termination, each termination agreement contains non-solicitation, non-competition, and confidentiality provisions.

**Double Trigger Change of Control.** Termination agreements with all NEOs are "double trigger", meaning that they provide for payments only upon involuntary termination or constructive dismissal of the executive following a change of control. Change of control is generally defined as a transaction or series of transactions whereby any person or combination of persons, acting jointly or in concert, beneficially owns, directly or indirectly, or exercises control or direction over, 35% or more of the outstanding voting securities of Suncor or its successor.

#### Termination and Change of Control Benefits
The table below shows the incremental amounts to which the NEOs (other than Mr. Smith) would be entitled under the circumstance of a Termination Event and/or change of control on December 31, 2025.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For all the NEOs, for termination with cause or voluntary resignation, no incremental value will be realized. Except for Mr. Kruger, none of the NEOs were eligible to voluntarily retire as of December 31, 2025. NEOs do not receive change of control payments upon a change of control except when accompanied by involuntary termination or constructive dismissal.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Short-Term Incentives include incremental annual bonus entitlement.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kruger is not eligible to participate in any Suncor pension plan. Ms. Powell and Messrs. Little, Oldreive and Zebedee would be granted an additional two years of executive defined benefit pension service in respect of the notice period under the terms of their termination agreements in the event of termination (without cause), whether in connection with a change of control or not. In addition, in connection with a change of control with termination or resignation, Ms. Powell and Mr. Zebedee, would be immediately vested under the SERP.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If Mr. Kruger's employment had been terminated without cause on December 31, 2025, he would be deemed a retiree under the provisions of the SOP, the PSU Plan and the RSU Plan in accordance with his employment agreement. As such, he would retain rights to PSUs and RSUs, and all stock

options would immediately vest. Long-Term Incentive includes the incremental value of all "in-the-money" unvested option-based awards that vest upon termination, calculated as the difference between the closing price of a common share on the TSX as at December 31, 2025 ($60.92) and the exercise price of the option.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Assumes involuntary termination without cause upon change of control. All stock options, PSUs, and RSUs would vest upon termination in accordance with the terms and conditions applicable to all employees that receive such awards.

(6) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Long-Term Incentive includes the incremental value of all "in-the-money" unvested option-based awards that would have vested during the 24-month notice period, calculated as the difference between the high-low average price of a common share on the TSX for the five days preceding December 31, 2025 ($59.82) and the exercise price of the option.

(7) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Assumes involuntary termination without cause upon change of control. Long-Term Incentive includes the incremental value of all "in-the-money" unvested option-based awards, calculated as the difference between the closing price of a common share on the TSX as at December 31, 2025 ($60.92) and the exercise price of the option. All stock options would vest upon termination in accordance with the terms and conditions applicable to all employees that receive such awards.

(8) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the event of resignation upon change of control, immediate vesting in the SERP is the only benefit; there are no further incremental pension benefits payable under this scenario.

(9) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Smith served as Chief Financial Officer from May 9, 2023 until November 1, 2025. Thereafter, he served as Executive Advisor until his formal retirement on December 31, 2025, and therefore has been excluded from the table above. See "Compensation Disclosure of Named Executive Officers" for a description of the payments Mr. Smith received in connection with his retirement.

### Indebtedness of Directors, Executive Officers and Senior Officers
No current or proposed director, executive officer or employee of Suncor, or any former director, executive officer or employee of Suncor, or any associate of any of the foregoing, is, or has been at any time during 2025, excluding routine indebtedness, indebted to Suncor or its subsidiaries, either in connection with the purchase of Suncor securities or otherwise.

### Summary of Incentive Plans
The following table sets forth information in respect of securities authorized for issuance under our equity compensation plans as at December 31, 2025.

---

The numbers shown beside "Equity compensation plans approved by security holders" refer to options granted under the SOP. In 2025, there were 4,560,383 options exercised pursuant to Suncor's SOP.

**Suncor Energy Stock Option Plan.** The SOP provides for the grant of stock options to purchase common shares, as well as the grant of stock appreciation rights (SARs) to eligible employees of Suncor. Eligible employees are persons who provide services to Suncor or any of its subsidiaries or partnerships and for whom we are required by law to make income source withholdings. Non-employee directors are not eligible for stock option awards or SARs under the SOP. The maximum number of common shares currently issuable pursuant to the SOP is 30,065,743 common shares (or 2.52% of the total issued and outstanding common shares on December 31, 2025). Stock options and SARs granted under the SOP may only be exercised during the lifetime of the participant, by such participant and are not assignable.

Options entitle the holder to purchase common shares at a price not less than the Market Value (as defined below) of the shares on the date of grant. Each SAR entitles the holder to receive, upon exercise, payment equal to the difference between the Market Value of a common share on exercise and the Market Value of a common share on the date of grant. The options and SARs generally have a term of seven years with a vesting schedule of one third per year over three years. "Market Value" means the simple average of the daily high and low prices at which common shares were traded in one or more board lots on the TSX over the five trading days immediately preceding the date of grant or exercise date, as the case may be. The exercise price of each option granted cannot be less than the fair market value of a common share at the time of grant.

Suncor does not grant SARs or tandem SARs to Canadian employees.

**Performance Share Unit Plan.** PSUs form a minimum of 50% of the equity component of total direct compensation for executives. Suncor uses two types of PSUs that are awarded under the PSU plan: Market PSUs and CPSUs.

[**TABLE OF CONTENTS**](#TOC)

Summary of Incentive Plans

**Market Performance Share Units.** A PSU award may pay out based on a vesting level between 0% and 200% contingent upon Suncor's performance over a three-year period. PSUs provide for notional dividend re-investment.

The selection of peer group companies for a PSU grant is based on a number of criteria including size (revenue and enterprise value), industry and business scope (integrated and exploration and production companies), oil weighting, peers of peers (the companies most often used as peer companies) and stock behavior and volatility. The selection criteria are reviewed periodically and approved by the HR&CC. The PSU peer group is reviewed annually for new grants, adjusted as appropriate and approved by the HR&CC. Of note, Chevron acquired Hess Corporation as of July 18, 2025.

To reinforce Suncor's vision of being Canada's leading energy provider and globally competitive, the HR&CC increased the financial impact of the Canadian peers by counting them three times, effectively creating a peer group of 17 companies, with Canadian competitors making up approximately 50% of the total performance peer group.

Vesting of PSU awards is determined based on Suncor's TSR relative to peer companies (70% of the vesting level) and Suncor's ROCE performance relative to targets (30% of the vesting level). Suncor uses a percentile rank approach to determine the relative TSR vesting level.

---

| |
|:---|
| Performance Factor <br> (% of PSUs vesting) |
| 200% 75<sup>th</sup> percentile and above  |
| Linear interpolation between 50<sup>th</sup> <br> and 75<sup>th</sup> percentiles  |
| 100% 50<sup>th</sup> percentile  |
| Linear interpolation between 25<sup>th</sup> <br> and 50<sup>th</sup> percentiles  |
| 50% 25<sup>th</sup> Percentile  |
| 0% Below 25<sup>th</sup> percentile  |

---

The HR&CC annually establishes five levels of ROCE performance that correspond to performance factors of 0%, 50%, 100%, 150%, and 200%. Interpolation is used when ROCE performance falls between established levels.

The HR&CC annually reviews the ROCE target and performance range considering updated economic forecasts and actual results through the first quarter of the year. Following this review, the HR&CC made no adjustments to targets for 2025.

Following a robust process, at the end of the three-year PSU grant performance period, TSR is measured and company percentile ranking and ROCE performance determine a performance factor and, if applicable, a payout is made to participants in cash. The final payout value is based on the number of vested PSUs (including dividend equivalents) multiplied by the market price of a common share, as calculated under the PSU Plan provisions.

In the past 10 years, 30% of PSU grant vesting levels have been below target and 70% have been at or above target based on performance results. The HR&CC did not exercise discretion in determining PSU payouts for the 2025 award.

**Climate Performance Share Units (CPSU).** A CPSU is granted under the PSU Plan to visibly align executive compensation with Suncor's climate objectives. Awards may pay out based on a vesting level between 0% and 200% contingent upon Suncor's performance over a three-year period. CPSUs provide for notional dividend re-investment.

First awarded in 2022, the CPSU program for Suncor's executives will continue as part of their compensation package in 2026. The issuance of CPSUs for each year of the program adjust the metrics in these categories to align with the targeted business activity over the duration of the vesting period. The 2026 CPSU awards will be focused on GHG emissions and intensity reduction in line with our commitment to decarbonize our base business.

**Restricted Share Unit Plan.** RSUs are granted to employees as part of their competitive compensation at Suncor. As RSU value is tied directly to Suncor's share price and dividends, RSUs serve to further align participants with shareholder interests.

Each RSU is a right to a cash payment, equivalent in value to one common share based on the value of Suncor's average common share price for the last 60 trading days up to and including maturity. Grants under the RSU Plan are administered by the HR&CC or its delegate. The RSU Plan provides for notional dividend reinvestment.

**Aggregate Potential Dilution.** The aggregate potential dilution of all issued, outstanding and authorized options under the SOP was 2.52% at December 31, 2025. Suncor has no other equity compensation plans involving newly issued securities.

**Burn Rate.** In 2025 there were 1,231,427 stock options granted under the SOP which resulted in a burn rate of 0.10%. In 2024, there were 1,194,582 stock options granted under the SOP which resulted in a burn rate of 0.09%. In 2023, there were 1,610,164 stock options granted under the SOP which resulted in a burn rate of 0.12%.

#### Additional Terms of Equity Compensation Plans.

---

| |
|:---|
| **Issuance of Shares under Plans** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • No one person or company is entitled to receive more than 5% of the issued and outstanding common shares pursuant to all equity-based compensation arrangements. <br>|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • The aggregate number of common shares which may be reserved for issuance under the SOP and all other security- based compensation arrangements of Suncor, must not, within any one-year period be issued, or at any time under such arrangements be issuable, to insiders (as defined in the TSX Company Manual) of Suncor in an amount exceeding 10% of Suncor's total issued and outstanding securities. <br>|
| **Amendment** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • The SOP contains an amendment provision providing that the Board may amend, suspend or terminate the SOP as it, in its discretion, may determine, without shareholder approval except for those amendments specifically requiring shareholder approval including: (a) an increase in the number of securities reserved under the SOP; (b) a reduction in an exercise price, or cancellation and reissue of options which benefits any option holder; (c) an amendment that extends the term of an award beyond its original expiry; (d) allowing awards granted under the SOP to be transferable or assignable other than for normal estate settlement purposes; and (e) any amendments to the amendment provision. <br>|
| **Impact of Change of Control, Reorganization or Other Events Affecting the Corporation** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • Suncor's equity compensation plans provide for adjustments to be made for the effect of certain events, including but not limited to, subdivision, consolidation, reorganization or other events which necessitate adjustments to the options in proportion with adjustments made to all common shares. <br>|
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • Upon a change of control, awards that have been granted under the SOP that remain outstanding on the change of control will be substituted with new awards on substantially the same terms and conditions. Provided the foregoing occurs, a holder's options will not vest upon or in connection with a change of control unless their employment is terminated within 12 months of the change of control (other than for cause), in which case the options will vest upon the holder's termination and shall expire three months following the termination date. However, where options that remain outstanding on a change of control are not substituted with new awards on substantially the same terms and in certain other circumstances (including at the discretion of the Board), the outstanding awards will immediately become exercisable. Any award not so exercised will expire at the closing of the change of control transaction. <br>|
| **Termination of Employment** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; • Pursuant to the SOP, in the event of an employee's involuntary termination (other than for cause, death, permitted leave, retirement or in connection with a change of control) or voluntary termination of employment, unvested options expire immediately, and vested options expire no later than three months from such termination. In the event of the holder's death, all options become exercisable by the holder's estate and shall expire no later than 12 months after the date of death. In the event of the holder's retirement, all options become exercisable and shall expire no later than 36 months after the date of retirement. If a holder is absent from work as a result of a permitted leave, the holder's options shall continue to vest for a period of 24 months from the date of commencement of the leave and the right to exercise such holder's options shall terminate no later than the expiration of 12 months from the date that is 24 months from the date of commencement of the leave. If the holder has not returned to active service prior to the expiration of 24 months from the date of commencement of the permitted leave then the holder's options which were not exercisable 24 months from the date of commencement of such leave shall immediately terminate. In the event of involuntary termination for cause, all options expire on the date of such termination. <br>|

### Claw Back Policy
The Board approved the adoption of a claw back policy for Suncor in 2012. The policy was updated in 2023 to comply with the recently adopted requirements of Rule 10D-1 under the Exchange Act and related rules of the NYSE. Under the claw back policy, if Suncor restates its financial results due to its material non-compliance with financial reporting requirements under applicable securities laws, it must recover, from any current or former executive officers, certain incentive-based compensation that was received by such executive officers during the three years preceding the date that such restatement was determined to be required. The recoverable amount would be the amount of incentive-based compensation received in excess of the amount that would otherwise have been received had it been determined based on the restated financial measure.

### Directors' and Officers' Insurance
Policies purchased by Suncor provide insurance for the directors and officers of Suncor against liability for any actual or alleged error, misstatement, misleading statement, act, omission, neglect or breach of duty in discharging their duties, individually or collectively. If Suncor is unable by law to indemnify individual directors and officers, including in an event of insolvency, there is no deductible and a US$200 million limit applies. In 2024, Suncor paid premiums of approximately US$1.6 million for directors' and officers' insurance for the 12-month period ending July 1, 2025. In 2025, Suncor paid premiums of approximately US$1.5 million for directors' and officers' insurance for the 12-month period ending July 1, 2026.

### Advance Notice By-law
Suncor's Amended and Restated By-Law No. 2, A By-Law Relating to Advance Notice of Nominations of Directors (By-Law No. 2), establishes a framework for advance notice of nominations of persons for election to the Board. By-Law No. 2 sets deadlines for a certain number of days before a shareholders' meeting for a shareholder to notify the corporation of their intention to nominate one or more directors, and explains the information that must be included with the notice for it to be valid. By-Law No. 2 applies at an annual meeting of shareholders or a special meeting of shareholders that was called to elect directors (whether or not also called for other purposes) and may be waived by the Board. It does not affect the ability of shareholders to requisition a meeting or make a proposal under the *Canada Business Corporations Act*.

In the case of an annual meeting of shareholders, notice must be given to the corporation not less than 30 days prior to the date of the meeting; provided, however, that if the meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the meeting was made, notice shall be made not later than the close of business on the tenth day following such public announcement. In the case of a special meeting (which is not also an annual meeting) of shareholders, notice must be given not later than the close of business on the fifteenth day following the date on which the first public announcement of the date of the meeting was made. In the case of an annual meeting of shareholders or a special meeting of shareholders called for the purpose of electing directors (whether or not also called for other purposes) where notice and access is used for delivery of proxy related materials, notice must be given not less than 40 days prior to the date of the meeting (but in any event, not prior to the date on which the first public announcement of the date of the meeting was made); provided, however, that if the meeting is to be held on a date that is less than 50 days after the date of such public announcement, notice shall be made, in the case of an annual meeting of shareholders, not later than the close of business on the tenth day following the date on which the first public announcement of the date of the meeting was made and, in the case of a special meeting of shareholders, not later than the close of business on the fifteenth day following the date of such public announcement. Shareholders should consult the full text of By-Law No. 2, which is available on Suncor's website at www.suncor.com and has been filed under the corporation's profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

As at the date of this Circular, the corporation had not received any additional director nominations.

### Corporate Governance
The Board is committed to maintaining high standards of corporate governance, and regularly reviews and updates its corporate governance processes and systems in light of changing practices, expectations and legal requirements.

Suncor is a Canadian reporting issuer. Our common shares are listed on both the TSX and the NYSE. Accordingly, our corporate governance practices reflect applicable rules and guidelines adopted by the Canadian Securities Administrators (the Canadian Requirements) and the SEC, including applicable rules adopted by the SEC to give effect to the provisions of the *Sarbanes-Oxley Act of 2002* (collectively, the SEC Requirements). NYSE corporate governance requirements are generally not applicable to non-U.S. companies; however, Suncor has reviewed its practices against the requirements of the NYSE applicable to U.S. domestic companies (NYSE Standards). Based on that review, Suncor's corporate governance practices in 2024 and 2025 did not differ from the NYSE Standards in any significant respect, with the exceptions described in Schedule C under the heading, "Compliance with NYSE Standards."

### Advisories
This Circular and the schedules hereto contain certain forward-looking statements and forward-looking information (collectively, forward-looking statements) within the meaning of applicable Canadian and U.S. securities laws and other information based on Suncor's current expectations, estimates, projections and assumptions that were made by the corporation in light of information available at the time the statement was made and consider Suncor's experience and its perception of historical trends, including expectations and assumptions concerning: the accuracy of reserves and resources estimates; commodity prices and interest and foreign exchange rates; the performance of assets and equipment; capital efficiencies and cost savings; applicable laws and government policies; future production rates; the sufficiency of budgeted capital expenditures in carrying out planned activities; the availability and cost of labour, services and infrastructure; the satisfaction by third parties of their obligations to Suncor; the development and execution of projects; and the receipt, in a timely manner, of regulatory and third party approvals. All statements and information that address expectations or projections about the future, and statements and information about Suncor's strategy for growth, expected and future expenditures or investment decisions, commodity prices, costs, schedules, production volumes, operating and financial results, future financing and capital activities, and the expected impact of future commitments are forward-looking statements. Some of the forward-looking statements and information may be identified by words like "expects", "anticipates", "will", "estimates", "plans", "scheduled", "intends", "believes", "projects", "indicates", "could", "focus", "vision", "goal", "outlook", "proposed", "target", "objective", "continue", "should", "may", "potential", "future", "opportunity", "would", "priority" and similar expressions.

Forward-looking statements in this Circular and the schedules hereto include references to: the business and procedure of the meeting; the composition of the Board following the meeting; factors to be taken into account by the Board in considering its approach to compensation in the future, including the results of the vote on the advisory resolution on the company's approach to executive compensation and feedback from shareholders; expectations regarding actions taken by the Board and Suncor management to further improve safety, operational and business performance, including the timing and effectiveness thereof; statements regarding the company's plan to focus on long-term value growth and returns to shareholders, including actions taken in support of such focus and the timing and effectiveness of such actions; the belief that Suncor structures compensation plans and programs and maintains guidelines and policies which limit excessive risk; the belief that there are no identified risks arising from the company's compensation policies and practices that are reasonably likely to have a material adverse impact on the company; the belief that Suncor provides the right balance in its overall rewards program to attract talent; statements regarding certain plans and strategies to be taken in support of sustainability initiatives and the outcomes and benefits thereof, including the decarbonization of Suncor's base business and the timing and effectiveness thereof; the expectation that none of the nominees for director will be unable to serve as director; the anticipated timing of the retirement of certain directors from the Board; the belief that a board comprised of people with diverse points of view can add greater value than a board comprised solely of directors with similar backgrounds; Suncor's commitment to long-term, sustainable, and environmentally-responsible development of the Canadian oil sands and offshore industry; the ability to fund future growth and energy transition opportunities while being resilient through the energy transition, including the actions and objectives to be taken in furtherance thereof; statements regarding the company's future climate-related disclosure practices, including the expectation that Suncor's continued transparent reporting will reflect the needs of investors and align with emerging regulations; and the establishment of subsequent objectives and capital allocation priorities.

Forward-looking statements are not guarantees of future performance and involve a number of risks and uncertainties, some that are similar to other oil and gas companies and some that are unique to Suncor. Suncor's actual results may differ materially from those expressed or implied by its forward-looking statements, so readers are cautioned not to place undue reliance on them.

Risks, uncertainties and other factors that could influence the financial and operating performance of all of Suncor's operating segments and activities include, but are not limited to: changes in general economic, market and business conditions, such as

The foregoing important factors are not exhaustive.

Many of these risk factors and other assumptions related to Suncor's forward-looking statements are discussed in further detail in Suncor's AIF, its MD&A, Form 40-F and other documents it files from time to time with securities regulatory authorities. Copies of these documents and Suncor's audited consolidated financial statements for the year ended December 31, 2025 are available without charge from Suncor at 150 – 6th Avenue S.W., Calgary, Alberta T2P 3E3, or by email request to info@suncor.com or by referring to the company's profile on SEDAR+ at www.sedarplus.ca or EDGAR at www.sec.gov. The forward-looking statements contained in this Circular and the schedules hereto are made as of the date hereof. Except as required by applicable securities laws, we assume no obligation to update publicly or otherwise revise any forward-looking statements or the foregoing risks and assumptions affecting such forward-looking statements, whether as a result of new information, future events or otherwise. Any forward-looking statements contained herein are expressly qualified by this cautionary statement.

Financial information in this Circular is reported in Canadian dollars, unless otherwise noted, and is provided in Suncor's audited consolidated financial statements for the year ended December 31, 2025 and the MD&A. Production volumes are presented on a working interest basis, before royalties, except for production volumes from the company's Libya operations, which are presented on an economic basis. Certain financial measures in this Circular – namely FFF, normalized free funds flow, AFFO and ROCE are not prescribed by GAAP. FFF, normalized free funds flow, AFFO and ROCE are defined and reconciled, to the most directly comparable GAAP measures, in the Non-GAAP and Other Financial Measures section in the applicable MD&A or Quarterly Report on file with Canadian securities commissions at www.sedarplus.ca and the Form 40-F on file with the SEC and each such reconciliation is incorporated by reference herein. These non-GAAP financial measures are included because management uses this information to analyze business performance, leverage and liquidity. These non-GAAP financial measures do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other companies. Therefore, these non-GAAP financial measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.

### Schedule A: Shareholder Proposal No. 1
The following shareholder proposal was submitted by British Columbia Investment Management Corporation (BCI), as primary filer, as well as Addenda Capital and the University Pension Plan Ontario (UPP), as co-filers. This proposal and its supporting statement represent the views of the shareholders submitting them. Suncor is required by applicable law to set forth the shareholder proposal and the related supporting statement in the Circular.

#### For the reasons set forth below in the "Board and Management Statement", the Board and management recommend that shareholders vote AGAINST this proposal.

#### Shareholder Proposal and Supporting Statement
Proposed Resolution

**RESOLVED:** Shareholders of Suncor Energy Inc. request that the Board of Directors of the Corporation prepare a report detailing the company's governance and oversight of its climate-related risks. The report should align with the climate-related governance indicators of internationally recognized standards such as the International Financial Reporting Standards (IFRS) S2 or the Canadian Sustainability Disclosure Standard (CSDS 2) building on the widely accepted recommendations of the Task Force on Climate related Financial Disclosures (TCFD).

Shareholders request that the report cover the governance processes, controls and procedures the company uses to monitor, manage and oversee climate-related risks and opportunities, such as:

• which governance body(ies) or individual(s) are responsible;

• how responsibilities are reflected in board committee mandates and terms of reference;

• how it is determined whether appropriate skills and competencies are available;

• how and how often information is shared;

• if and how target setting and associated progress is overseen and monitored;

• how performance metrics are included in executive compensation; and,

• how responsibilities are split between management and the board.

The report should be made available prior to the Corporation's 2027 annual general meeting.

#### Supporting Statement
Suncor currently has limited climate-related disclosures including on governance. Yet, the company operates in an emissions-intensive industry and identifies carbon as one of its Principal Risks in its Annual Risk Review. Shareholders require reliable, objective, consistent, comparable, and timely data to make informed investment decisions and to understand the potential impacts of climate-related risks and opportunities on investee companies and investment portfolios.

The company's 2025 Proxy Circular identifies the entire board as responsible for the oversight of carbon risk. It also assesses every board director as having significant experience in Environment, Health and Safety, including climate risk management, but there are no details on the criteria used to assess this competency. Compared to Canadian oilsands peers such as Cenovus Energy and Canadian Natural Resources, Suncor lacks explicit language related to carbon risk governance in committee charters and lacks a standalone Climate & Emissions expertise area as part of its director skills matrix.

The Climate Action 100+ Net Zero Company Benchmark assesses the company as not disclosing clear evidence of Board or Board committee oversight of climate change risks, lagging the assessment of 11 out of 12 other North American oil & gas companies covered by CA100+ on this indicator.

The International Sustainability Standards Board (ISSB) published IFRS S2, which was adapted by the Canadian Sustainability Standards Board (CSSB) to CSDS 2. Suncor was a financial contributor to the proposed ISSB headquarters in Canada and a company representative was a CSSB implementation committee member. Nearly 40 jurisdictions accounting for almost 60% of global GDP are adopting or otherwise using the ISSB Standards<sup>(1)</sup>.

The requested disclosure would be in line with Suncor's long history of TCFD-aligned reporting and would provide shareholders with the information required to assess the management of a self-identified principal risk to the company.

We ask shareholders to vote FOR this proposal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

[**TABLE OF CONTENTS**](#TOC)

#### Board and Management Statement

#### Suncor's Board and management recommend voting AGAINST this proposal for the following reasons:
Suncor uses our Circular, report on sustainability, annual report, and other regulatory filings to disclose information about our governance and oversight of climate-related risks. The issuance of the proposed additional voluntary report would require a significant amount of company resources and would be redundant.

Changes to the *Competition Act* (Canada) (the "Competition Act") have also created significant uncertainty for companies like Suncor to communicate publicly about their work to manage environmental performance, including actions and plans to address climate change. Voluntarily expanding our public disclosure practices on climate-related matters at this point in time could expose Suncor to potential claims brought under the Competition Act, with a risk of significant penalties. Future amendments to the Competition Act and rules on climate-related disclosures from Canadian securities regulators could clarify how we can continue to provide this information to our shareholders in the future.

Suncor is, and intends to remain, in full compliance with all applicable legal, regulatory, and industry reporting obligations with respect to financial, risk management, emissions and climate-related reporting.

#### Recommendation
The Board and management recommend shareholders vote AGAINST this proposal.

### Schedule C: Corporate Governance Summary
Throughout this summary, there are references to information available on the Suncor Energy Inc. ("Suncor" or the "corporation") website. All such information is available at www.suncor.com under the "Who We Are – Governance" tab. Shareholders may request printed copies from Suncor at the address on the back of the Circular, or by email request to invest@suncor.com. <br>

Suncor has a comprehensive corporate governance program which complies with all applicable rules and regulations and considers all applicable corporate governance best practices.

![[MISSING IMAGE: tb_governance-pn.jpg]](tb_governance-pn.jpg)

#### Board of Directors – Composition and Independence
The cornerstone of Suncor's governance system is its Board, whose duty is to oversee the management of Suncor's business and affairs. The composition of the Board and its independence are important elements of this system. Richard M. Kruger, Suncor's President and CEO, is the only member of the Board who is not independent. Following the 2026 annual general meeting (the AGM) and assuming that all nominees for director are elected as contemplated in the Circular, 9 of 10 members (90%) of the Board will be independent directors. A short biography of each individual standing for election to the Board can be found starting on page 9 of the Circular.

Suncor's independent directors meet in-camera at each Board and committee meeting without Mr. Kruger or any other member of management present. The Board sessions are presided over by Suncor's independent Board Chair. The committee sessions are presided over by the independent Chairs of the respective committees. The applicable Chair then communicates to management any issues or matters discussed at the in-camera meetings requiring management attention.

The Board has approved written position descriptions for the Board Chair and committee Chairs. The Board Chair's accountabilities include shareholder meetings, management of the Board, Board effectiveness, working with management, and liaising with stakeholders. All of the position descriptions are available on Suncor's website.

These position descriptions supplement the Terms of Reference, as described below. The position descriptions are reviewed annually by the Governance Committee. Any changes to the position descriptions are presented by the Governance Committee to the full Board for approval.

The Governance Committee annually reviews and assesses the independence of Board members. The Board's independence policy and criteria include a description of certain relationships that operate as a complete bar to independence as well as additional requirements applicable to members of the Audit Committee. Suncor's independence criteria are consistent with the Canadian Requirements and the SEC Requirements.

[**TABLE OF CONTENTS**](#TOC)

Corporate Governance Summary

In applying the independence criteria, the Governance Committee reviews and analyzes the existence, materiality and effect of any relationships between Suncor and each of its directors, either directly, through a family member, or as a partner, shareholder or officer of another organization that has a relationship with Suncor. The Governance Committee determines in each case whether the relationships could be reasonably expected to interfere with the exercise of the director's independent judgement.

Some members of the Board are involved with companies with which Suncor has business relationships. The Governance Committee has reviewed each of these relationships and determined that none of these relationships impair the independence of the individual directors. The Board's conflict of interest policy precludes directors from voting with respect to any contract or transaction where a potential conflict of interest could exist, should it be considered by the Board (see "Conflicts of Interest and Related Party Transactions").

**Other Public Company Board Memberships.** While Suncor does not limit the number of public company boards a director serves on, the Terms of Reference provide that each director should ensure that they are able to devote sufficient time and energy to carry out their duties effectively. The Chair of the Board, in conjunction with the Governance Committee, reviews requests from Suncor's CEO to sit on the board of outside business organizations. The Suncor CEO could only join another public company board with the Board's consent.

Some of Suncor's directors sit on the boards of other public companies, the particulars of which are set out on pages 9 to 15 of the Circular. None of Suncor's directors are "overboarded" as currently defined by the guidelines established by either Institutional Shareholder Services, Inc. or Glass, Lewis & Co. In addition, none of Suncor's directors currently serve together on the board of another public company. Suncor does not restrict board interlocks but recognizes that it is important for directors to remain impartial and independent even if they have a common board membership.

#### Nomination of Directors and Selection Process
The Governance Committee conducts the selection process for new nominees to the Board pursuant to its policy on the selection of Board members (the Selection Process Policy). Directors are chosen for their integrity, character, sound and independent judgment, breadth of experience, insight and knowledge, and business acumen. The Governance Committee has emphasized the Board's commitment to having a Board comprised of individuals having a diversity of backgrounds, experience, and skill sets. The inclusion of an appropriate number of female directors and the identification of female candidates is also a key search criterion in the director selection and nomination process as per the terms of the Board diversity policy (the Diversity Policy). In addition, for over 25 years, the Board has determined that it is critical to ensure at least one Board member identifies as Indigenous. See "Inclusion and Diversity" for a discussion of the Diversity Policy which is incorporated into the Board selection process.

Pursuant to the policies of the Board, the assessment and selection process is undertaken by the Governance Committee as needed and consists of several considerations, including (i) an inventory of capabilities, competencies, skills, qualities, and attributes of the current Board; (ii) identifying attributes desired to maintain or increase Board effectiveness; and (iii) maintaining an evergreen list of potential Board candidates as well as working with an external recruitment firm, as needed, to ensure a robust recruitment process is followed for each new Board member. The role of the CEO in that process is limited. The Board has determined that the skills and experience of the Board currently map well to Suncor's business strategy.

The following table lists the experience and skills of the directors standing for election at the AGM. Below the table is a description of each skill and experience.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kruger is the only non-independent director nominee as he is also an executive officer of Suncor.

![[MISSING IMAGE: tb_skillsexp-pn.jpg]](tb_skillsexp-pn.jpg)

The above inventory is assessed as required to identify any experience and skills to be added to the Board in light of the Board's current needs and priorities. The Governance Committee uses this assessment as a key input for identifying selection criteria describing the skills, experiences, qualifications, diversity and personal qualities desired in potential new Board members.

The Governance Committee identifies candidates from a number of sources and utilizes the services of a third-party executive search firm, as necessary, for example to complete reference and background checks on Board candidates. When a vacancy occurs or is pending, the Governance Committee identifies a short list of potential candidates to pursue further. In addition to the factors listed above, the Governance Committee considers whether each candidate can devote sufficient time and resources to their duties as a Board member. The identification of diverse candidates is also a key search criterion in the director selection process. Where it deems appropriate the Governance Committee may recommend that a search be focused on candidates who have certain diverse characteristics in addition to other relevant and needed skills and experience. For example, the

Corporate Governance Summary

Governance Committee sought out and selected J.P. Gladu to ensure the Board continued to include an Indigenous perspective following Mel Benson's retirement in 2021.

Throughout the process, the Governance Committee provides updates to the Board and solicits input on candidates. Candidates are interviewed by the Board Chair as well as the Chair and other members of the Governance Committee. All directors are given the opportunity to interview any candidate proposed for appointment to the Board. The Governance Committee ultimately provides its recommendation on Board candidates to the full Board. Candidates may be appointed by the Board to hold office for a term expiring not later than the close of the next annual meeting of shareholders.

#### Inclusion and Diversity
**Board of Directors.** The Board aims to be composed of directors who have a range of perspectives, insights and views in relation to the issues affecting Suncor. The Board's Diversity Policy confirms that the Board should include individuals from diverse backgrounds. This includes, but is not limited to, the representation of those who identify as women, Indigenous peoples, visible minorities, and persons with disabilities. It also includes consideration of diverse business experience, professional expertise, personal skills, stakeholder perspectives, geographic background, and other diverse experiences or attributes.

The Selection Process Policy requires the Governance Committee to conduct periodic assessments to consider the level of representation on the Board of the various attributes enumerated in the Diversity Policy. The Diversity Policy is reviewed annually to assess its effectiveness in promoting a diverse Board. Board members also have the opportunity to evaluate, on an annual basis, the effectiveness of the director selection process through the Evaluation Process (as defined herein); see "Annual Evaluation Process" under the heading "Board Tenure and Renewal."

The Board has a gender diversity goal of 30% for women. The Board is currently 45% women. Following the AGM and assuming that all nominees for director are elected as contemplated in the Circular, four of ten directors (40%) on the Board will be women and one of the ten directors (10%) on the Board will be Indigenous. The Board does not view additional goals as the most effective way of ensuring a diverse board and believes its current make up reflects the principles of diversity set out in the Diversity Policy.

The graphs below show the breakdown of the directors standing for election at the 2026 meeting by gender and age.

**Suncor Management.** Suncor is committed to building an inclusive, results-oriented and high-performance culture where all members of our team feel safe, valued and respected. This is based on the strongly held belief that through the inclusion of people with diverse genders, backgrounds, cultures, experience and perspectives, we can deliver industry leading performance.

Suncor does not set formal representation targets for executive officer or senior leadership positions; rather, the organization seeks to establish diverse representation in the workplace and at all levels of leadership through barrier-free processes to identify the best-qualified candidates and by providing equitable development opportunities. Suncor weighs several factors in selecting candidates for executive officer and senior leadership positions: the skills and experience required in roles; the skills, experience, and attributes of prospective candidates; and the diverse make-up of the leadership team. As at December 31, 2025, among 47 executive and senior leaders at Suncor, fifteen (32%) are women, five (11%) identify as members of a visible minority, one (2%) identifies as Indigenous and three (6%) identify as persons with a disability.

The organization values the benefits of inclusion and diversity. The organization is focused on providing an equitable and inclusive workplace, increasing women's representation across the workforce, and continuing to advance Indigenous workforce representation and development in support of our Journey of Reconciliation.

#### Board Tenure and Renewal
The Board's goal is to be made up of members who have a range of perspectives, insights and views in relation to issues affecting Suncor. In furtherance of that goal, the Board has implemented two primary mechanisms of board renewal: the Retirement Policy and an annual evaluation process, each of which is described in detail below.

The Board has not adopted term limits for directors as it believes the Retirement Policy and the annual board evaluation process are effective in achieving the appropriate level of renewal of the Board's membership.

The tenure of directors standing for election at the 2026 meeting can be summarized as follows, with the average director tenure being 3.5 years:

![[MISSING IMAGE: pc_director-pn.jpg]](pc_director-pn.jpg)

**Retirement Policy.** The Board has adopted the Retirement Policy, which provides that all directors, other than management directors, must retire from the Board upon completion of their term of office at the annual meeting of shareholders following their 72<sup>nd</sup> birthday. The Governance Committee, in consultation with the Board Chair, has the authority, under exceptional circumstances, to recommend extension of the term of a Board member if the retirement of such director would not be in the best interests of Board continuity and effectiveness. Any such extension is subject to the approval of the Board.

**Annual Evaluation Process.** Suncor's Board Effectiveness Evaluations Policy establishes an annual process (the Evaluation Process) whereby directors are provided with an opportunity to evaluate the effectiveness of the Board, its committees, the Board Chair, committee Chairs, and individual directors and to identify areas where effectiveness may be enhanced. The results of the Evaluation Process carried out in 2025 confirmed that all directors and committees, and the Board as a whole, effectively fulfilled their roles and responsibilities.

![[MISSING IMAGE: tb_reviews-pn.jpg]](tb_reviews-pn.jpg)

The Evaluation Process involves the solicitation of input from individual directors through an annual survey presented in two parts: (i) an evaluation form that explores the directors' views and solicits feedback on how well they believe the Board and its committees, including their Chairs, are performing (the Board Effectiveness Survey); and (ii) a peer feedback survey (the Peer Survey) that explores the directors' views and solicits feedback on their assessment of other directors' performance, including their contributions and participation in Board discussions and debate, accountability, knowledge, experience, demonstration of high ethical standards and communication and persuasion skills. Both surveys also underwent a comprehensive review and update in 2024 to ensure the content is relevant, focused, and in line with governance best practices.

#### Board Effectiveness Review
Confidential responses to the Board Effectiveness Survey are tabulated and analyzed by the Corporate Secretary and presented in a report which is circulated to the Chair of the Governance Committee and Board Chair. Key recommendations of the report are discussed at the Governance Committee. The Chair of the Governance Committee supports the Board Chair in reporting to the full Board on the survey results.

[**TABLE OF CONTENTS**](#TOC)

Corporate Governance Summary

Information obtained from the answers to surveys assists the Board in determining whether any of the Board or committee mandates or Board processes or policies should be revised. The outcome of the process also informs, in part, the Board's priorities for the year.

#### Peer Review
The results of the Peer Survey are consolidated by the Corporate Secretary and provided to the Board Chair. Individual directors receive their personal results.

The Board Chair conducts one-on-one meetings with each director to discuss their peer review results and to receive input on governance, risk and strategy. The Chair of the Governance Committee discusses the Board Chair's peer review results with the Board Chair. A discussion regarding the Board Chair's performance also occurs at a Governance Committee meeting and with the Board absent the Board Chair. The one-on-one meetings are completed prior to the first Board and committee meetings held in each calendar year. This allows any input provided on governance, risk, and strategy to be incorporated into the recommendations arising from the Evaluation Process. Once the peer review meetings are completed, the Board Chair prepares a summary of key items arising from these discussions which are discussed in-camera at the Governance Committee and at the meeting of the full Board.

#### Terms of Reference
The Board has adopted terms of reference (the Terms of Reference), which serve as the charter of the Board. The Terms of Reference are reviewed by the Board annually. They include a general overview of the Board's role in Suncor's governance, a statement of key guidelines and policies applicable to the Board and its committees, and a mandate that describes its major responsibilities, goals and duties.

The full text of the Terms of Reference is set out in Schedule D.

The Board discharges certain of its responsibilities through its four standing committees: the Audit Committee, the Environment, Health, Safety and Sustainable Development (EHS&SD) Committee, the Governance Committee and the Human Resources and Compensation Committee (HR&CC). Each standing committee has a mandate, which it reviews annually and updates as appropriate. All changes to mandates are also reviewed annually by the Governance Committee and recommended for approval to the Board. The mandates are available on Suncor's website. Pursuant to its Terms of Reference the Board may also create ad hoc committees to examine specific issues on behalf of the Board.

The Governance Committee, with input from the Board Chair, makes recommendations to the Board regarding committee appointments. Committee appointment considerations include diversity of backgrounds and director experience relevant to the committee's key roles.

With limited exceptions, the committees generally do not have decision-making authority; rather, they convey their findings and recommendations on matters falling within their mandates to the full Board.

The committees also have the authority to conduct independent investigations into matters that fall within the scope of their responsibilities and may engage external advisors (as may the full Board or an individual director), at Suncor's expense, to assist them in fulfilling their mandate.

The Board delegates day-to-day management of Suncor's business to the CEO and other members of senior management. A management control process policy, adopted by the Board, defines and sets limits on the authority delegated by the Board.

The Board has approved a position description for the CEO, which includes a general description of the role as well as specific accountabilities in the areas of strategic planning, financial results, leadership, safety, government, environment and social relations and management's relationship with the Board. A copy of the CEO position description is available on Suncor's website.

The following is a description of some key duties of the Board as set out in the Terms of Reference. For more information, please refer to "Board Committees," the Terms of Reference, and the mandates of the Board committees available on Suncor's website.

**Ethics.** The Terms of Reference require the Board, through the CEO, to establish Suncor's standards of conduct, including the corporation's general moral and ethical tone and compliance with applicable laws. The CEO in turn is accountable for setting a high ethical tone and fostering a culture of integrity throughout the organization. The Board plays an active role in ensuring a high standard of corporate ethics and integrity through its oversight of Suncor's written standards of business conduct (the Code) and compliance program (see Ethical Business Conduct), and through its assessment and evaluation of the performance of the CEO.

[**TABLE OF CONTENTS**](#TOC)

**Strategic Planning.** The Board provides stewardship and oversight of Suncor's strategic planning process.

The Governance Committee works with management to design the agenda for the annual strategy meeting to ensure that it appropriately reflects a discussion of key strategic issues, initiatives and principal risks.

In 2025 the key topics reviewed at the Board's annual strategic planning meeting included: the global macro-energy environment; the Canadian energy landscape; Suncor's portfolio of assets; Suncor's near-term goals; key strategic issues; and, mid- and long-term opportunities for value enhancement.

**Stakeholder Communications.** Suncor has a written standard that provides direction for Suncor's communications with shareholders, investment analysts, other stakeholders, and the public generally. This standard sets out measures to avoid selective disclosure of material information, identifies designated Suncor spokespersons, and establishes internal review processes for key public communications. The Code addresses Suncor's obligations for continuous and timely disclosure of material information and sets standards requiring directors, officers, employees, and contract workers trading in Suncor shares and other securities to comply with applicable law.

Suncor has disclosure controls and procedures designed to ensure that material information relating to Suncor is made known to our CEO and Chief Financial Officer (CFO). Suncor has a Disclosure Committee, chaired by the Vice President Finance and Controller, and has designed and implemented due diligence procedures to support financial reporting and the certification of financial reports by the CEO and CFO.

Suncor discusses its operations with its shareholders and other stakeholders through a variety of channels, including its periodic financial reports, securities filings, news releases, webcasts, external website, social media posts, briefing sessions, group meetings, and other company publications. Suncor encourages and seeks stakeholder feedback through various channels including corporate communications and investor and community relations programs.

**Shareholder Engagement.** Suncor recognizes the importance of strong and consistent engagement with its shareholders. The Board is specifically mandated to ensure systems are in place for communication with Suncor's shareholders and other stakeholders and that these systems are appropriately resourced.

Suncor maintains email and regular mail addresses for shareholder feedback and questions. In addition, Suncor encourages shareholders to virtually attend Suncor's annual meeting. Other interested parties may also attend virtually. The annual meeting provides a valuable opportunity to hear directly from, and ask questions to, Suncor's Board Chair, CEO, CFO, and management about the results of Suncor's business and operations, as well as its strategic plans. Registered shareholders and duly appointed proxyholders may participate and ask questions at the AGM. Questions can be submitted online in written format (see "Meeting Participation, Voting and Proxies: Questions and Answers" on pages 3 to 7 of the Circular).

Suncor's senior management also holds quarterly conference calls and webcasts with the investment community to review Suncor's most recently released financial and operating results.

The Board recognizes that it is also important for the Board to communicate with shareholders, including organizations that represent or advise shareholders (collectively, Interested Parties) on matters of governance, and to that end, has adopted a Shareholder Communication and Engagement Policy (the Engagement Policy). In accordance with the Engagement Policy, Interested Parties may communicate to the Board in writing to express their views on matters that are important to them, by addressing their correspondence to the Board in care of the Corporate Secretary at the address on the back page of the Circular, or via email at: invest@suncor.com, subject line: Attention: Chair of the Board / Chair of [Insert Board Committee Name] c/o Corporate Secretary. The Board has determined that questions or concerns related to the Board and senior management succession processes, executive and Board compensation, Board level corporate governance and other matters that are within the scope of the Board's supervisory and oversight duties, as set out in its Terms of Reference, may appropriately be addressed to, and by, the Board. In addition, the Engagement Policy recognizes that in certain circumstances it may be appropriate for Board members, generally through the Board Chair or the Chair of a committee, to meet with an Interested Party, and sets out criteria to be considered if the Board receives a meeting request and terms applicable to the conduct of any such meeting.

Members of the Board and the management team, as appropriate, engage with various corporate governance stakeholders and shareholders to listen to their opinions. This engagement involves dialogue on a number of topics, including: safety, operational performance and reliability, corporate strategy, executive leadership, corporate governance, sustainability strategy and disclosure, and operating results.

Corporate Governance Summary

![[MISSING IMAGE: tb_riskreviews-pn.jpg]](tb_riskreviews-pn.jpg)

**Risk Oversight.** Suncor is committed to a proactive program of enterprise risk management intended to enable decision- making through consistent identification and assessment of risks inherent to its assets, activities and operations. Some of these risks are common to operations in the oil and gas industry as a whole, while some are unique to Suncor. The Board oversees Suncor's Enterprise Risk Management Program (the ERM Program), and in accordance with the ERM Program, senior management, including the CEO, undertakes an entity-wide process to identify, assess and report on the significant risks to Suncor's business and management's strategies to appropriately mitigate such risks. For example, as a result of the ERM Program, the Board and management continues to consider appropriate policies and practices with respect to emerging opportunities and risks of Artificial Intelligence to Suncor's business.

Each year the Board reviews Suncor's principal risks. The Governance Committee oversees the enterprise risk management governance model and processes by conducting periodic reviews of Suncor's enterprise risk management process with the objective of ensuring the principal risks of Suncor's business are being appropriately overseen by the Board and its committees. The Audit Committee also reviews and approves the appointment of the executive responsible for Suncor's enterprise risk and internal audit function, who provides reports directly to the Audit Committee regarding internal audit matters.

The following table sets forth Suncor's principal risks and the Board committee and/or full Board to which each principal risk is mapped for oversight.

For a detailed explanation of the material risks applicable to Suncor and its businesses, see "Risk Factors" in Suncor's AIF, filed under Suncor's profile at www.sedarplus.ca.

**Succession Planning and Monitoring/Evaluating Senior Management.** The Board ensures the continuity of executive management by appointing a CEO and overseeing succession planning. The Board has a robust CEO and executive leadership succession process, which emphasizes the proactive development of internal candidates, to support Suncor's long term success. The Board is assisted in its oversight of CEO succession by the Governance Committee and the HR&CC. The Governance Committee assists with governance of the leadership succession planning process. The HR&CC ensures that appropriate executive succession planning (for both planned and unplanned events) and performance evaluation processes (including development and career planning) are in place and operating effectively. The HR&CC also reviews significant changes to the organization's structure as they arise and the impact these changes have on executive roles.

The HR&CC annually reviews the succession planning process and internal candidate evaluations and development planning for the CEO and other executive leadership positions, and reports to the Board on these matters. As part of this process, the CEO, supported by the Chief Human Resources Officer, reviews candidates for the CEO and other executive leadership positions with the HR&CC and the Board.

**C-8 Management Proxy Circular 2026** Suncor Energy Inc.

[**TABLE OF CONTENTS**](#TOC)

The Board also reviews Suncor's processes for identifying successors for its vice presidents, and other key leadership roles within the organization. Successors are identified using a process that rigorously assesses leadership capability and aptitude and potential for increased levels of responsibility. This includes evaluation on multiple criteria, including past performance, personal aspiration, engagement, adaptability, experience and capabilities. For a discussion of how Suncor considers diversity in this process, see "Inclusion and Diversity."

The Board encourages the CEO to expose the Board to Suncor's executives and potential candidates, both for succession planning and career development and to provide the Board with a broader perspective on issues relevant to Suncor. Directors are provided with opportunities to meet with Suncor employees through attendance at events hosted by Suncor or when they visit Suncor's facilities.

The HR&CC assists the Board in monitoring the CEO's performance by conducting an annual performance review against predetermined goals and criteria (including the goal of succession planning). The HR&CC also reviews with the CEO the performance of his direct reports.

**Expectations and Responsibilities of Directors.** The Terms of Reference, supplemented by a Board approved accountability statement for directors, identify the key expectations of Board members. These documents are available on Suncor's website.

Directors are required to devote sufficient time, effort and energy to their role as a Suncor director in order to effectively discharge their duties to Suncor. Pursuant to the Terms of Reference, Audit Committee members must not be members of the audit committees of more than two other public companies, unless the Board determines that simultaneous service on a greater number of audit committees would not impair the member's ability to effectively serve on Suncor's Audit Committee. In 2025, the Board determined that Jane Peverett's service on the audit committees of three other public companies would not impair her ability to effectively serve on Suncor's Audit Committee.

**Internal Controls.** The Board is mandated to ensure processes are in place to monitor and maintain the integrity of Suncor's internal controls and management information systems. The Audit Committee assists the Board in this regard and monitors the effectiveness and integrity of Suncor's financial reporting, management information, internal controls of business processes and internal audit function (excluding operations integrity audit matters, which are specifically within the mandate of the EHS&SD Committee).

The Audit Committee exercises general oversight over the internal audit function. The appointment or termination of the executive responsible for internal audit is approved by the Audit Committee. This individual has a direct reporting relationship with the committee and meets with it, in the absence of other members of management, at least quarterly. The Audit Committee also reviews any recommended appointee to the position of CFO.

#### Board Committees
In addition to the responsibilities described elsewhere in this Schedule, the following provides a brief summary of the key functions, roles and responsibilities of Suncor's Board committees. The complete text of the mandate of each Board committee is available on Suncor's website.

**Governance Committee.** The Governance Committee assists the Board in matters related to: general corporate governance, the corporate strategy role of the Board, risk management process governance, CEO succession process governance, Board succession, performance and compensation as well as corporate ethics, standards, and compliance (see "Ethics", "Strategic Planning", and "Risk Oversight" under the heading "Terms of Reference").

In its governance role, the Governance Committee is mandated to determine Suncor's overall approach to governance issues and key corporate governance principles. In doing so, it closely monitors emerging best practices in governance. In addition, the Corporate Secretary, or her delegate, attends conferences and meetings on governance and updates the committee on developing trends and practices. Suncor also reviews recommendations of governance and shareholder advisory organizations and periodically participates in benchmarking studies undertaken by such organizations to assess its governance practices. The corporation's legal function monitors changes in law, administrative policy and stock exchange requirements relating to governance, and provides updates to the Governance Committee.

The Governance Committee reviews and reports to the Board on directors' compensation. The Governance Committee has developed guidelines for director compensation based on, among other factors, directors' roles and responsibilities and an analysis of the competitive position of Suncor's director compensation program. The Governance Committee reviews the competitiveness and form of Board compensation and makes recommendations to the full Board on Board compensation and share ownership guidelines for directors. The Board sets director compensation based upon these recommendations.

Corporate Governance Summary

**Audit Committee.** The Audit Committee assists the Board in matters relating to Suncor's external auditors and the external audit process, oil and natural gas reserves reporting, financial reporting and related public communication, and certain other key financial matters. The Audit Committee also assists the Board in matters relating to internal controls of Suncor's business and financial processes and the internal audit function (see "Internal Controls," under the heading "Terms of Reference").

The Audit Committee plays a key role in relation to Suncor's external auditors. It initiates and approves their engagement (including fees) or termination, subject to shareholder approval, and monitors and reviews their independence, effectiveness, performance and quality control processes and procedures.

The Audit Committee reviews, with management and external auditors, and as appropriate approves, significant financial reporting matters, the conduct and results of the annual audit and significant finance and accounting policies and other financial matters. The Audit Committee also reviews Suncor's annual and quarterly financial statements, annual and quarterly MD&A and AIF/Form 40-F. The Audit Committee approves quarterly financial statements and quarterly MD&A through authority delegated by the Board and makes recommendations to the Board with respect to approval of the annual disclosure documents.

The Audit Committee plays a key oversight role in the evaluation and reporting of Suncor's oil and natural gas reserves. This includes review of Suncor's procedures relating to reporting and disclosure, as well as those for providing information to Suncor's independent reserves evaluators. The Audit Committee approves the appointment and terms of engagement (including fees) of the reserves evaluators, and reviews their qualifications, performance and independence and any changes in their appointment.

Suncor's reserves data and report of the independent reserves evaluators are annually reviewed by the Audit Committee prior to approval by the full Board.

The Audit Committee reviews Suncor's policies and practices with respect to cash management, financial derivatives, financing, credit, insurance, taxation, commodities trading and related matters. It also reviews the assets, financial performance, funding status and strategy of Suncor's pension plans and any audits conducted of Suncor's standards of business conduct compliance program (see "Ethical Business Conduct").

Members of the Audit Committee are required to be financially literate. All of Suncor's directors, including all members of the Audit Committee, are considered financially literate. In addition, at least one member of the Audit Committee must be determined by the Board to be an "audit committee financial expert." The Board has determined Ms. Kneale and Ms. Peverett to be such experts. The criteria for assessing the financial literacy of directors, and whether they qualify as an "audit committee financial expert," are set out in the Terms of Reference.

For additional information about Suncor's Audit Committee, including the Audit Committee Mandate and Pre-approval Policies and Procedures, see "Audit Committee Information" in Suncor's AIF, filed under Suncor's profile at www.sedarplus.ca.

**Environment, Health, Safety and Sustainable Development Committee.** The EHS&SD Committee reviews the effectiveness with which Suncor meets its obligations and achieves its objectives pertaining to the environment, health, safety and sustainable development. This includes the effectiveness of management's establishment and maintenance of appropriate EHS&SD policies as well as monitoring the adequacy and effectiveness of Suncor's Operational Excellence Management System (an overarching framework to manage operational risk), and related business processes. The EHS&SD Committee also monitors management's performance and emerging trends and issues in these areas. In fulfilling its role, the EHS&SD Committee reviews management stewardship reports as well as the findings of significant external and internal environmental, health and safety investigations, assessments, reviews and audits.

Public disclosure documents that report on Suncor's sustainability progress, plans and performance objectives are also reviewed by the EHS&SD Committee.

The EHS&SD Committee assists the Board in matters pertaining to the integrity of Suncor's physical assets, by monitoring the adequacy of Suncor's internal controls as they relate to physical site security, operational risks of its physical assets and matters of environment, health, safety and sustainable development. The EHS&SD Committee regularly engages in the oversight of the corporation's development of its safety and reliability improvement plans.

The EHS&SD Committee also reviews and advises the Board (and the HR&CC for the purposes of executive incentive plans) regarding the safety and environment-related performance goals, metrics and targets.

**Human Resources and Compensation Committee.** The HR&CC assists the Board by annually reviewing the performance of the CEO and recommending his total compensation to the full Board. The corporate objectives for which the CEO is responsible are set annually by the Board in consultation with the HR&CC and the Board Chair. The HR&CC annually reviews the CEO's performance against these objectives and against the key accountabilities of his position, as set out in the CEO's position description. The HR&CC reports its assessment to the full Board which ultimately approves CEO compensation.

**C-10 Management Proxy Circular 2026** Suncor Energy Inc.

[**TABLE OF CONTENTS**](#TOC)

The HR&CC also reviews annually the CEO's evaluation of the other senior executives within the organization and approves their total compensation. For more information about the HR&CC and the process and criteria for determining the CEO's total compensation, see "Compensation Discussion and Analysis" in the Circular. See also "Succession Planning and Monitoring/ Evaluating Senior Management," under the heading "Terms of Reference."

In addition, the HR&CC oversees management of the impact of workforce changes and reviews corporate plans and processes for equity, inclusion and diversity.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Romasko resigned from the Board due to medical reasons effective August 8, 2025, and his meeting attendance has not been included as part of the calculation of overall director attendance for Board and Committee meetings in 2025. As a result of Mr. Romasko's resignation, Mr. Girling was appointed to the Audit Committee effective August 27, 2025, after which point his attendance is recorded for meetings of the Audit Committee. Prior to this date with respect to all committees of the Board, and after this date with respect to all committees except for the Audit Committee, Mr. Girling, in his capacity as Board Chair and on a non-voting basis, attended such meetings of the committees of the Board as he determined appropriate.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Mr. Kruger is not a member of any standing committee and therefore his attendance is only recorded for meetings of the Board. However, throughout the year, Mr. Kruger attended certain committee meetings on a non-voting basis at the invitation of the committees in his capacity as an officer of Suncor.

Corporate Governance Summary

#### Orientation and Continuing Education
Each new member of the Board participates in a formal orientation program. The orientation program includes in-person meetings with senior management on key operational, environmental, business, financial and legal topics central to Suncor's business and operations. The orientation program also focuses on the role of the Board, its committees and its directors and the nature and operation of Suncor's business.

A directors' handbook, containing information about the Board and Suncor, including Suncor's core governance documents, is made available to each director upon joining the Board. The handbook is continuously updated and is available for viewing by directors through a secure directors' portal.

Presentations and tours at the sites of Suncor's principal operations are provided to directors on a periodic basis, often in conjunction with Board meetings, for the purpose of directly acquainting directors with Suncor's operations and the communities in which they are located.

The Governance Committee oversees the Board's continuing education program. In conjunction with Board meetings, management and, from time to time, external experts present focused information to directors on topics pertinent to Suncor's business, including: significant emerging risks or issues; changes to the legal, regulatory or industry environment; and, opportunities presented by new technologies.

The Board's Director Continuing Education Policy underscores Suncor's recognition of learning and education as key elements of continued board effectiveness. As reflected in the policy, Suncor encourages directors to engage in continued maintenance and upgrading of their skills and provides supports for directors to enroll in courses and programs that enhance and supplement their knowledge and skills in areas relevant to their role on the Board. Suncor purchases memberships for directors in the Institute of Corporate Directors and may also purchase memberships upon request for directors in the National Association of Corporate Directors to allow them to access additional educational opportunities offered by those organizations such as conferences, presentations and seminars.

The independent directors of the Board and Board committees participate in continuing education through external, third-party programs and internal Suncor sessions. Internal sessions include business and operational updates, meetings with the corporation's senior management, and site visits. In 2025, one or more Suncor directors participated in the continuing education programs outlined in the table below:

#### Ethical Business Conduct
Sound, ethical business practices are fundamental to Suncor's business. Suncor's standards for the ethical conduct of our business are set forth in the Code, which applies to Suncor's directors, officers, employees and contract workers. The Code requires compliance with legal requirements and Suncor's values. Topics addressed in the Code include competition and trade relations, conflicts of interest and the protection and proper use of corporate assets and opportunities, confidentiality, disclosure of material information, trading in shares and securities of Suncor, communications to the public, improper payments, respectful workplace standards, accounting, reporting and business controls. The President & CEO delivers a clear message that all representatives of Suncor are expected to conduct business in a safe, fair, honest, respectful and ethical manner.

The Code is supported by detailed policies and an annual compliance program. All Directors, officers, employees and contract workers are required annually to complete an annual affirmation process.

Suncor also has a supplier code of conduct that highlights the values that are important to Suncor and is a guide to the standard of behavior Suncor expects of all suppliers, contractors, consultants and other third parties with whom Suncor does business. The supplier code of conduct addresses topics such as safety, human rights, harassment, bribery and corruption and confidential information, among others. Compliance with the supplier code of conduct is a standard term of all Suncor supply chain contracts.

The Board exercises stewardship over the Code in several respects. Suncor's internal auditors audit the compliance program at least once every three years and the leader responsible for internal audit, who has a direct reporting relationship with the Audit Committee, reports on the audit to that committee. Further, the Board has appointed a Chief Compliance Officer who reviews Suncor's Ethics and Compliance Programs and related matters with the Governance Committee on an annual basis.

Moreover, at least once annually, the Code is reviewed and if appropriate, updated and management reports to the Governance Committee annually on this process. The Governance Committee reviews any changes and ensures the Code continues to reflect Suncor's commitment to ethics and integrity, and addresses related legal requirements. Any waivers of Code requirements for Suncor's executive officers or members of the Board must be approved by the Board and disclosed. No such waivers were granted in 2025.

Corporate Governance Summary

![[MISSING IMAGE: tb_conduct-pn.jpg]](tb_conduct-pn.jpg)

Suncor encourages employees to raise ethical concerns with Suncor management through any of: Suncor's legal, corporate security, human resources or internal audit departments, without fear of retaliation.

In addition, Suncor's "Integrity Hotline" provides a means for Suncor employees to raise issues of concern anonymously, with a third-party service provider. The Integrity Hotline is available 24 hours a day, seven days a week. Any issues of a serious nature are investigated pursuant to Suncor's internal investigations standard and protocols. The Audit Committee receives regular updates on activities relating to the Integrity Hotline. A committee comprised of senior leaders from Legal Affairs, Human Resources and Environment, Health and Safety is responsible for ensuring that all alleged Code violations are investigated.

Suncor provides additional specialized training for employees for matters governed by the Code where it is determined such training would be necessary or beneficial. For example, certain employees directly involved with Suncor's international and offshore operations are required to periodically attend focused workshops, which address, among other items, compliance with sanctions and anti-bribery and anti-corruption legislation and best practices for operating in international jurisdictions where Suncor operates. In addition, certain employees in Suncor's downstream operations receive training focused on competition and anti-trust issues.

#### Conflicts of Interest and Related Party Transactions
The Board has a policy relating to directors' conflicts of interest, including related party transactions. Pursuant to this policy, directors are required to maintain with the Corporate Secretary a current list of all other entities in which they have a material interest,<sup>(1)</sup> or on which they serve as a director, trustee or in a similar capacity. This list is made available to all directors through the directors' portal. Directors must immediately advise the Corporate Secretary of any deletions, additions or other changes to any information in their declaration of interest.

If the change involves a change in the director's principal occupation or an appointment as director, officer or trustee of any for- profit or not-for-profit organization, the director must also provide prior notification to the Board Chair, who will determine whether the change would be inconsistent with the director's duties as a member of the Board. In appropriate circumstances, the director's resignation may be required.

The policy sets out clear procedures applicable in the event conflicts arise. If a director is a party to, or has an interest in any party to, a contract or transaction before the Board (regardless of the materiality of the contract or transaction), the director must immediately advise the Board Chair or the particular committee Chair. The director's conflict or potential conflict is recorded in the minutes of the meeting and the director is required to absent himself or herself from the meeting for any material discussions or deliberations concerning the subject matter of the contract or transaction. The director is required to abstain from voting on any resolution in respect of such contract or transaction.

The Corporate Secretary ensures that directors do not receive Board materials in situations where the subject matter of those materials could involve an actual or potential conflict of interest.

This approach is consistent with the requirements of the *Canada Business Corporations Act*. In addition, the Governance Committee annually ascertains and reviews related party transactions in conjunction with making director independence determinations.

As part of the Board's independence analysis, directors complete questionnaires that include information regarding related party transactions and Suncor completes internal searches on payments to and from entities in which directors have a material interest or act as a director, trustee or in a similar capacity (see "Board of Directors – Composition and Independence").

#### Compliance with NYSE Standards
Suncor's corporate governance practices meet or exceed all applicable Canadian Requirements and SEC Requirements.

Except as disclosed below, Suncor's corporate governance practices are in compliance with NYSE Standards in all significant respects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; As set forth in the conflict of interest policy, a director is considered to have a material interest in an entity if he or she is a director or officer of that entity, performs an executive function for the entity or has some other material interest in the entity. A director who beneficially holds less than 5% of the outstanding securities of any publicly traded entity and who does not derive any other benefit from such entity not available to other public security-holders, shall not be considered to hold a material interest in such entity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• **Approval of Equity Compensation Plans.** Suncor is not required to and does not comply with Section 303A.08 of the NYSE Listed Company Manual which requires shareholder approval of all equity compensation plans and any material revisions thereto, regardless of whether the securities to be delivered under such plans are newly issued or purchased on the open market. The TSX rules, which Suncor complies with, only require shareholder approval for certain of Suncor's equity compensation plans in accordance with a specific amendment provision, as approved by shareholders at the 2007 annual and special meeting and by the TSX. See "Summary of Incentive Plans" on page 44 of the Circular.

• **Independence Standards.** The Board is responsible for determining whether or not each director is independent. In making this determination, the Board has adopted the definition of "independence" as set forth in the Canadian Requirements (specifically National Instrument 52-110 – *Audit Committees*) and SEC Requirements (specifically Rule 10A-3 under the U.S. *Securities Exchange Act of 1934*, as amended). The Board has not adopted, and is not required to adopt, the director independence standards contained in Section 303A.02 of the NYSE's Listed Company Manual, including with respect to its audit committee and compensation committee. The Board has not adopted, nor is it required to adopt, procedures to implement Section 303A.05(c)(iv) of the NYSE's Listed Company Manual in respect of compensation committee advisor independence.

Board Terms of Reference

### Schedule D: Board Terms of Reference

#### Part I: Overview
The *Canada Business Corporations Act* (the "Act"), the governing statute of Suncor Energy Inc. ("Suncor" or the "Corporation"), provides "that the directors shall manage or supervise the management of the business and affairs of a corporation…". In practice, as a Board of Directors cannot "manage" a corporation such as Suncor in the sense of directing its day-to-day operations, the overarching role and legal duty of Suncor's Board of Directors is to "supervise" the management of Suncor's business and affairs. Accordingly, the Board of Directors oversees development of the overall strategic direction and policy framework for Suncor. This responsibility is discharged through Board oversight of Suncor's management, which is responsible for the day-to-day conduct of the business. The Board, through the Chief Executive Officer ("CEO"), sets standards of conduct, including the Corporation's general moral and ethical tone, compliance with applicable laws, standards for financial practices and reporting, qualitative standards for operations and products and other standards that reflect the views of the Board as to the conduct of the business in the best interests of the Corporation.

In general, then, the Board is responsible for the selection, monitoring and evaluation of executive management, and for overseeing the ways in which Suncor's business and affairs are managed. In this way, the Board assumes responsibility for the stewardship of the Corporation. Specific responsibilities which facilitate the discharge of the Board's stewardship responsibilities include: the strategic planning process, risk identification and oversight, ensuring that effective stakeholder communication policies are in place, and ensuring the integrity of internal controls and management information systems. These responsibilities, and others, are addressed in more detail in the Board's Mandate, comprising Part IV of these Terms of Reference.

The Board of Directors discharges its responsibilities with the assistance of Board committees. The committees advise and formulate recommendations to the Board, but do not, except in limited and specifically identified circumstances, have the authority to approve matters on behalf of the Board of Directors. General guidelines relating to Board committees comprise Part III of these Terms of Reference. In addition, each committee has a written mandate, setting out the scope of its operations, and its key roles and responsibilities. Position descriptions of the Board Committee Chairs and the Board Chair set out the related principles, framework and accountabilities for those key roles in Suncor's Board governance.

The CEO of Suncor is delegated the responsibility for the day-to-day management of the Corporation and for providing the Corporation with leadership. The CEO discharges these responsibilities by formulating Corporation policies and proposed actions, and, where appropriate, presenting them to the Board for approval. The Corporation's Management Control Process Policy explicitly identifies actions that have been specifically delegated to the CEO, and those which are reserved to the Board of Directors. In addition, the Board has plenary power, and has the power to specify and modify the authority and duties of management as it sees fit with a view to Suncor's best interests and in accordance with current standards. The Act also identifies certain matters which must be considered by the Board as a whole and may not be delegated to a committee or to management. These matters include:

• any submission to the shareholders of a question or matter requiring the approval of the shareholders;

• the filling of a vacancy among the directors or in the office of the external auditor;

• the manner of and terms for the issuance of securities;

• the declaration of dividends;

• the purchase, redemption or any other form of acquisition of shares issued by the Corporation;

• the payment of a commission to any person in consideration of the purchase or agreement to purchase shares of the Corporation from the Corporation or from any other person, or procuring or agreeing to procure purchasers for any such shares;

• the approval of management proxy circulars;

• the approval of any take-over bid circular or directors' circular;

• the approval of the audited annual financial statements of the Corporation; and

• the adoption, amendment or repeal of by-laws of the Corporation**.** 

Key stewardship responsibilities of the Board include overseeing the development of the Corporation's goals, strategies and plans and the fundamental objectives and policies within which the business is operated. The CEO is required, in a timely and candid manner, to keep the Board fully informed of the progress of the Corporation toward the achievement of its goals, strategies and plans, and the Board of Directors continually evaluates the performance of executive management toward these achievements.

#### Part II: Board Guidelines
The following have been adopted by the Board as the guidelines applicable to the Board and its operations:

• These Terms of Reference for the Board of Directors (which include the Board Guidelines, Committee Guidelines, Board Mandate and Board Forward Agenda, setting out the important issues that must be addressed by the Board of Directors annually), and the mandates and forward agendas of the Board committees, constitute the charters of the Board and committees respectively, and are reviewed by the Board annually and updated as deemed appropriate. These charters are supplemented by the position descriptions for the Board Chair and Board Committee Chairs, as well as the Director Accountability Statement.

• The CEO is responsible for leading the development of long-range plans for the Corporation, including its goals and strategies. The Board, both directly and through its committees, participates in discussions of strategy, by responding to and contributing ideas. The Board annually reviews the Corporation's annual business plan (including the annual capital budget), and in so doing endorses the strategies as reflected in the Corporation's long-range plan.

• The Board believes that the appropriate size for the Board is between 10 and 14 members.

• Directors stand for re-election annually.

• The Board maintains a Mandatory Retirement and Change of Circumstance Policy and reviews the policy periodically to ensure it continues to serve the Corporation's best interests. The Board maintains a policy permitting directors to retain outside advisors at the expense of the Corporation, subject to the written approval of any of the Board Chair, the Chair of the committee proposing to retain outside advisors, or the Governance Committee. In exercising their approval authority, the Board Chair, Board Committee Chair or Governance Committee, as the case may be, will establish, on a case by case basis, reasonable monetary limits and other controls as deemed appropriate.

• In order to support the alignment of Directors' interests with those of Suncor's shareholders, Directors shall own during the term of their directorship, within five years of being appointed or elected to the Board, a minimum value of Suncor common shares, DSUs or any combination thereof, as determined periodically by the Governance Committee. Where management share ownership guidelines are more onerous than the foregoing, management directors shall be subject to the management share ownership guidelines rather than these Directors' Share Ownership Guidelines.

• The Board should be comprised of a majority of independent directors. The Board has defined an independent director in written independence criteria, based on definitions under applicable law<sup>(1)</sup>. On an annual basis, the Board of Directors shall consider and affirmatively determine whether each individual director is independent, in accordance with the criteria.

• The membership of the CEO on the Board of Directors is valuable and conducive to effective decision making. However, there should be no more than three inside<sup>(2)</sup> directors on the Board of Directors.

• The Board supports the separation of the role of Chair from the role of CEO.

• The Board will evaluate the performance of the CEO at least annually. The evaluation will be based on criteria which includes the performance of the business and the accomplishment of the CEO's qualitative and quantitative objectives as established at the beginning of each fiscal year of the Corporation, and the creation and fostering within the Corporation of a culture of integrity.

• The Board Chair will work with the CEO to establish the agenda for each Board meeting. Each Board member is free to suggest the inclusion of items on the agenda. Whenever feasible, important issues should be dealt with over the course of two meetings. The first such meeting would allow for a thorough briefing of the Board, and the second would allow for final discussion and a decision.

• The Board will hold at least five meetings per year, one of which shall be principally devoted to strategy. An additional meeting shall be scheduled for approval of the annual proxy circular, annual information form and other annual disclosure documents, as necessary.

• Whenever feasible, the Board will receive materials at least one full week in advance of meetings. Presentations on specific subjects at Board meetings will only briefly summarize the material sent so discussion at the meeting can focus on questions and issues. Directors are expected to have reviewed these materials prior to attendance at Board and committee meetings and are expected to be prepared to engage in meaningful discussion and provide considered, constructive and thoughtful feedback and commentary at meetings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Suncor's corporate governance practices reflect applicable rules and guidelines adopted by the Canadian Securities Administrators (the "Canadian Requirements") and the U.S. Securities and Exchange Commission ("SEC"), including applicable rules adopted by the SEC to give effect to the provisions of the Sarbanes-Oxley Act of 2002 (collectively, the "SEC Requirements").

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; An inside director is an officer (other than an officer serving as such in a non-executive capacity) or employee of the Corporation.

Board Terms of Reference

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• Board meeting dates will be established sufficiently in advance (at least one year and longer if practical) to minimize conflict with other commitments on Directors' schedules. Directors are accordingly expected to make every reasonable effort to attend all meetings of the Board and its committees, if not in person, then by telephone, or other electronic means.

• While the Board does not restrict the number of public company boards that a director may serve on, each director should ensure that he or she is able to devote sufficient time and energy to carrying out their duties effectively.

• The Board encourages the CEO to bring other executives into Board meetings. The presence of such executives is expected to bring additional insights into the discussions, because of the executives' personal involvement in, and knowledge of, specific agenda items. The benefit of exposing the Board to other executives, for succession planning and career development purposes, is recognized.

• The Board is responsible for selecting its own members, and for assessing the performance of individual directors, as well as the effectiveness of Board committees and the Board of Directors as a whole. The Board delegates management of the selection processes to the Governance Committee. The selection process includes consideration of the competencies and skills the Board, as a whole, should possess, against those of existing directors, and a consideration of the competencies and skills each new nominee will bring to the Board, as well as their ability to devote sufficient time and attention to fulfilling the role of director. Board members should also represent a diversity of backgrounds, experience and skills. The Board has adopted a Board Diversity Policy and a Selection Process for New Members Policy, which support this principle and ensure that diversity is a consideration in director selection. The Board ultimately determines nominees that will be included in the Corporation's management proxy circular.

• The outgoing Chair of the Board, or in the absence of the outgoing Chair, a director elected by resolution of the Board, shall manage the process of selecting a new Chair by seeking nominations, determining the willingness of each nominee to take on the role of Chair of the Board, and preside over the selection process.

• Succession and management development plans will be reviewed by the Human Resources & Compensation Committee and reported on annually to the Board.

• During each Board meeting, the Board of Directors shall meet on an "in camera" basis without management. Such in camera meetings shall be presided over by the independent Board Chair. In addition, at least once annually, the independent directors will meet in the absence of both management and non-independent directors.

• From time to time the Board will visit a Suncor location other than Calgary. The purpose is to facilitate continual exposure of Board members to the Corporation's operations and the communities in which they are carried out.

#### Part III: Committee Guidelines
• The Board has four standing committees: the Audit Committee, the Governance Committee, the Human Resources and Compensation Committee ("HR&CC"), and the Environment, Health, Safety & Sustainable Development Committee ("EHS&SD"). From time to time the Board may create ad hoc committees to examine specific issues on behalf of the Board. Each standing committee maintains a written mandate and reviews that mandate annually. Any recommendations to amend committee mandates are reviewed by the Governance Committee for recommendation to the Board of Directors.

• The Governance Committee, with input from the Board Chair, plans Board committee appointments (including the designation of a committee Chair) for recommendation to and appointment by the Board. The constitution of the committees shall be considered annually. In accordance with the Corporation's By-laws, unless otherwise determined by resolution of the Board of Directors, a majority of the members of a committee shall constitute a quorum for meetings of committees.

• Each committee shall be comprised of a minimum of three and a maximum of six directors. Each committee shall have a non-member Secretary who may be a member of management of the Corporation. The Chair of each committee, in consultation with the committee Secretary, shall determine the agenda for each committee meeting.

• The Board supports the principle that committee Chairs should be rotated regularly while preserving continuity.

• Except where otherwise specified in these terms of reference or in the Corporation's By-laws, each committee shall have the power to determine its own rules of procedure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

• The Audit Committee will consist entirely of outside, independent<sup>(3)</sup> directors. In addition, all members of the Audit Committee must be, in the judgment of the Board of the Directors, financially literate <sup>(4)</sup>, and at least one member of the Audit Committee must be an audit committee financial expert<sup>(5)</sup>.

• In general Audit Committee members will not simultaneously be members of the Audit Committee of more than two other public companies, unless the Board of Directors affirmatively determines that simultaneous service on a greater number of audit committees would not impair the member's ability to effectively serve on Suncor's Audit Committee. Any such determination by the Board of Directors may be disclosed in the Corporation's management proxy circular.

• The HR&CC will consist entirely of outside, independent directors.

• The Governance Committee shall consist entirely of outside, independent directors.

• The Board Chair, by standing invitation, is considered an ex-officio of the Board standing committees of which he or she is not a listed member.

• During each committee meeting, the committee shall meet on an "in camera" basis without management. Such in camera meetings shall be presided over by the Chair of the committee, if an independent director, or other committee member who is an independent director, as selected by the independent directors on the committee.
