Such information, which may be considered financial outlooks within the meaning of applicable Canadian securities laws, has been approved by management of the Company and is based on current expectations, estimates, projections and assumptions (collectively, the “Factors”), including those outlined in our 2026 corporate guidance, as applicable, which are available on www.suncor.com/guidance (which Factors are incorporated by reference into this presentation), as well as the assumptions, uncertainties, risk factors and qualifications set out in this presentation and discussed below. Management believes that such Factors were reasonable as of the date of this presentation, having regard to the industry, business, financial conditions, plans and prospects of Suncor. These projections are provided to describe the prospective performance of the company and to assist in understanding the company’s future plans and expectations, and users of this information are cautioned that such information may not be appropriate for other purposes. Further, such information is highly subjective and should not be relied on as necessarily indicative of future results and actual results may differ significantly from such projections. Forward-looking statements are based on various assumptions, expectations and opinions that are believed by management to be reasonable at the time, including assumptions regarding: - market and economic conditions and market competition; - prevailing business environments, commodity and carbon prices and inflation, interest, tax and foreign exchange rates; - the performance of technology, assets and equipment in a manner consistent with management’s current expectations; - expected capital efficiencies and cost savings; - prevailing regulatory, tax, legal and government policies; - future production rates; - the development and execution of projects in a manner consistent with management’s current expectations; - product supply and demand; - dividends and share repurchases approved and declared; - expected synergies and the ability to sustain reductions in costs; - the ability to access external sources of debt and equity capital on acceptable terms; - the timing and the costs of well and pipeline construction being consistent with current expectations; - the sufficiency of budgeted capital expenditures in carrying out planned activities; - the timely receipt of regulatory and other approvals; - the timing of sanction decisions and Board of Directors’ approval; - the availability and cost of labour, services, and infrastructure; - the satisfaction by third parties of their obligations to Suncor; - anticipated improvements in performance of assets; - the expected timing and impact of technology development; - assumptions contained in or relevant to Suncor’s 2026 corporate guidance; and - those factors and assumptions described under the heading “Advisories – Forward-Looking Statements” in Suncor’s annual report for the year ended December 31, 2025 (the “2025 Annual Report”) and under the heading “Advisory – Forward-Looking Statements and Non-GAAP Financial Measures” in Suncor’s Annual Information Form (the “2025 AIF”) and Form 40-F dated February 25, 2026 and February 26, 2026, respectively, which sections are incorporated by reference into this presentation and which documents are available on the Company’s SEDAR+ profile at www.sedarplus.ca. continued …

Slide 57 — Advisories

S U N C O R E N E R G Y 57 Advisories S U N C O R E N E R G Y 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) which may cause actual results, events or performance to differ materially from that expressed or implied by forward looking statements. Such risks and uncertainties include, but are not limited to: - adverse changes in market and economic conditions, business environments, commodity and carbon prices and/or inflation, interest, tax and foreign exchange rates; - assets and facilities not performing as anticipated; - expected debottlenecks, cost savings, capital reductions and margin improvements not being achieved to the extent anticipated; - imprecision of reserves and resources estimates and estimates of recoverable quantities of oil, natural gas and liquids from Suncor’s properties; - adverse changes in royalty, tax, environmental and other laws or regulations or the interpretations of such laws or regulations; - deteriorations in applicable political and economic conditions; and - the other risks and uncertainties described under the heading “Risk Factors” in the 2025 Annual Report, which section is incorporated by reference into this presentation. Except as required by applicable securities laws, Suncor disclaims any intention or obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Suncor’s actual results may differ materially from those expressed or implied by its forward-looking statements, so users of such information are cautioned not to place undue reliance on them. Non-GAAP and Other Financial Measures – Certain financial measures and ratios in this presentation – namely adjusted funds from operations, free funds flow, normalized free funds flow, net debt and related per share amounts or metrics that contain such measures – are not prescribed by GAAP. All non-GAAP measures and non-GAAP ratios presented in this presentation do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other companies. Therefore, these non-GAAP measures and non-GAAP ratios should not be considered in isolation or as a substitute for measures and ratios of performance prepared in accordance with GAAP. All non- GAAP measures and non-GAAP ratios are included because management uses the information to analyze business performance, leverage and liquidity and therefore may be considered useful information by investors. See the “Advisories - Non-GAAP and Other Financial Measures” section of the 2025 Annual Report. All non-GAAP measures presented in this presentation are defined and reconciled, as applicable, in the 2025 Annual Report in the “Advisories - Non-GAAP and Other Financial Measures” section or Suncor’s report to shareholders for the fourth quarter of 2025, dated February 3, 2026, in the “Non-GAAP and Other Financial Measures Advisory” each of which are available on the company’s SEDAR+ profile available at www.sedarplus.ca and each such reconciliation is incorporated by reference into this presentation. WTI breakeven price is a supplementary financial measure that represents the U.S. dollar WTI price per barrel that is equal to Suncor’s operating costs, dividend payment amount and sustaining capital on a per barrel basis. Management uses WTI breakeven price to measure the company’s performance and believes it provides investors with important information regarding the efficiency and profitability of Suncor’s operations. Reserves – Unless noted otherwise, reserves information presented in this presentation for Suncor is presented as Suncor’s working interest (operating and non-operating) before deduction of royalties, and without including any royalty interests of Suncor, and is at December 31, 2025. For more information on Suncor’s reserves, including definitions of proved and probable reserves, Suncor’s interest, location of the reserves and the product types reasonably expected please see the 2025 AIF. Reserves data is based upon evaluations conducted by independent qualified reserves evaluators as defined in NI 51-101. Contingent Resources – Unless noted otherwise, contingent resources information presented in this presentation is based upon evaluations conducted by GLJ Ltd. (GLJ), contained in its report dated March 27, 2026 with an effective date of December 31, 2025. For more information on Suncor’s contingent resources, please see the Statement of Contingent Resources dated March 30, 2026 which is available on the Company’s SEDAR+ profile at www.sedarplus.ca. There is uncertainty that it will be commercially viable to produce any portion of the contingent resources.
