Suncor’s adjusted operating earnings were $1.325 billion ($1.10 per common share) in the fourth quarter of 2025, compared to $1.566 billion ($1.25 per common share) in the prior year quarter, with the decrease primarily due to lower upstream price realizations net of decreased royalties, and a foreign exchange loss on working capital items compared to a gain in the prior year quarter, partially offset by increased refinery margins and increased upstream production, downstream throughput and sales volumes.
Net earnings were $1.476 billion ($1.23 per common share) in the fourth quarter of 2025, compared to $818 million ($0.65 per common share) in the prior year quarter. In addition to the factors impacting adjusted operating earnings, net earnings for the fourth quarter of 2025 and the prior year quarter were impacted by the items shown in the table above.
Adjusted funds from operations were $3.218 billion ($2.68 per common share) in the fourth quarter of 2025, compared to $3.493 billion ($2.78 per common share) in the prior year quarter, and were primarily influenced by the same factors impacting adjusted operating earnings.
Cash flow provided by operating activities, which includes changes in non-cash working capital, were $3.921 billion ($3.27 per common share) in the fourth quarter of 2025, compared to $5.083 billion ($4.05 per common share) in the prior year quarter.
Operating, selling and general (OS&G) expenses were $3.518 billion in the fourth quarter of 2025, compared to $3.411 billion in the prior year quarter, with the increase primarily due to higher commodity input costs. Operations, selling and corporate costs remained relatively flat despite higher production and sales volumes in both upstream and downstream.

Total Oil Sands bitumen production increased to a quarterly record of 992,700 bbls/d, compared to 951,500 bbls/d in the prior year quarter, primarily due to strong mining performance, and included record fourth quarter production at Fort Hills, which achieved 90% of nameplate capacity in 2025 delivering on the three-year mine improvement plan.
The company’s net synthetic crude oil (SCO) production increased to a quarterly record of 557,000 bbls/d, compared to 543,600 bbls/d in the prior year quarter, as the company’s production mix benefited from increased upgrader availability due to decreased planned maintenance activities in the current quarter and continued strong upgrader reliability.
Non-upgraded bitumen production increased to 288,400 bbls/d in the fourth quarter of 2025, compared to 273,900 bbls/d in the prior year quarter, primarily due to record bitumen production, partially offset by increased upgrader availability.
Exploration and Production (E&P) production increased to 63,600 bbls/d in the fourth quarter of 2025, compared to 57,500 bbls/d in the prior year quarter, and included increased production at Hebron and the addition of production at White Rose, which restarted in the first quarter of 2025.
Refining throughput increased to a quarterly record of 504,200 bbls/d with refinery utilization of 108%, compared to 486,200 bbls/d and 104%, respectively in the prior year quarter. The increase was primarily due to continued strong operating performance through the current quarter, which saw all four refineries exceed 100% utilization.
Refined product sales increased to a fourth quarter record of 640,400 bbls/d, compared to 613,300 bbls/d in the prior year quarter, primarily due to higher refinery production and continued investment in retail growth, as well as leveraging strategic partnerships.

Suncor’s current NCIB will terminate on March 2, 2026. The company intends to renew the NCIB program subsequent to the expiration of its current NCIB.

Between March 3, 2025 and January 30, 2026, pursuant to Suncor’s current NCIB, Suncor repurchased 50,474,677 common shares on the open market, representing the equivalent of 4.1% of its common shares as at February 18, 2025, for $2.8 billion, at a weighted average price of $55.46 per common share.

The actual number of common shares that may be repurchased under the NCIB and the timing of any such repurchases will be determined by Suncor. The company believes that, depending on the trading price of its common shares and other relevant factors, repurchasing its own shares represents an attractive investment opportunity and is in the best interests of the company and its shareholders. The company does not expect the decision to allocate cash to repurchase shares will affect its long-term strategy.

Governance Update

Jennifer Kneale was appointed to Suncor’s Board of Directors on February 3, 2026 and is a member of both the audit committee and the environment, health, safety and sustainable development committee. She is currently the President of Targa Resources Corp., an integrated midstream company headquartered in Houston, Texas. Prior to joining Targa, Ms. Kneale spent more than 10 years in the financial services industry, primarily in roles in private equity, asset management and investment banking.

Suncor’s adjusted operating earnings were $1.325 billion ($1.10 per common share) in the fourth quarter of 2025, compared to $1.566 billion ($1.25 per common share) in the prior year quarter, with the decrease primarily due to lower upstream price realizations net of decreased royalties, and a foreign exchange loss on working capital items compared to a gain in the prior year quarter, partially offset by increased refinery margins and increased upstream production, downstream throughput and sales volumes.

Adjusted Funds from Operations and Cash Flow Provided by Operating Activities

Adjusted funds from operations were $3.218 billion ($2.68 per common share) in the fourth quarter of 2025, compared to $3.493 billion ($2.78 per common share) in the prior year quarter, and were primarily influenced by the same factors impacting adjusted operating earnings discussed above.

Cash flow provided by operating activities, which includes changes in non-cash working capital, was $3.921 billion ($3.27 per common share) in the fourth quarter of 2025, compared to $5.083 billion ($4.05 per common share) in the prior year quarter. In addition to the factors impacting adjusted funds from operations, cash flow provided by operating activities was impacted by a smaller source of cash associated with the company’s working capital balances in the fourth quarter of 2025, compared to the prior year quarter. Working capital is subject to fluctuations based on commodity prices, the timing of transactions and seasonal factors. The source of cash in the fourth quarter of 2025 was primarily due to an increase in accounts payable and accrued liabilities and the timing of tax installment payments.

In the fourth quarter of 2024, share-based compensation expense of $147 million included $54 million in the Oil Sands segment, $4 million in the E&P segment, $23 million in the R&M segment and $66 million in the Corporate and Eliminations segment.

OS&G expenses were $3.518 billion in the fourth quarter of 2025, compared to $3.411 billion in the prior year quarter, with the increase primarily due to higher commodity input costs. Operations, selling and corporate costs remained relatively flat despite higher production and sales volumes in both upstream and downstream. The company’s exposure to commodity costs is partially mitigated by revenue from power sales that are recorded in operating revenues.

(1)Oil Sands Base upgrader yields are approximately 80% of bitumen throughput and Syncrude upgrader yield is approximately 85% of bitumen throughput.
(2)Upgrader utilization rates are calculated using total upgraded production, inclusive of internally consumed products and inter-asset transfers.
(3)Both Oil Sands operations and Syncrude produce diesel and other products, which are internally consumed in operations. In the fourth quarter of 2025, Oil Sands operations produced 17,000 bbls/d of internally consumed products, of which 8,500 bbls/d was consumed at Oil Sands operations, 7,000 bbls/d was consumed at Fort Hills and 1,500 bbls/d was consumed at Syncrude. Syncrude produced 3,600 bbls/d of internally consumed products.
(4)In the fourth quarter of 2025, upgraded inter-asset transfers consisted of 9,200 bbls/d of sour SCO that was transferred from Oil Sands operations to Syncrude.
(5)In the fourth quarter of 2025, non-upgraded inter-asset transfers consisted of 46,500 bbls/d of bitumen that was transferred from Fort Hills to Oil Sands Base, 8,500 bbls/d of bitumen that was transferred from Firebag to Syncrude and 100 bbls/d of bitumen that was transferred from Syncrude to Oil Sands operations.

Total Oil Sands bitumen production increased to a quarterly record of 992,700 bbls/d, compared to 951,500 bbls/d in the prior year quarter, primarily due to strong mining performance, and included record fourth quarter production at Fort Hills, which achieved 90% of nameplate capacity in 2025 delivering on the three-year mine improvement plan.

The company’s net SCO production increased to a quarterly record of 557,000 bbls/d, compared to 543,600 bbls/d in the prior year quarter, with record upgrader utilization of 109% at Syncrude and strong upgrader utilization of 103% at Oil Sands Base, compared to 105% and 102%, respectively, in the prior year quarter. The increase in net SCO production was primarily due to higher upgrader availability in the current period related to decreased planned maintenance activities in the current quarter and continued strong upgrader reliability.

Non-upgraded bitumen production increased to 288,400 bbls/d in the fourth quarter of 2025, compared to 273,900 bbls/d in the prior year quarter, primarily due to record bitumen production, partially offset by increased upgrader availability.

Oil Sands price realizations decreased in the fourth quarter of 2025 compared to the prior year quarter, primarily due to weaker crude oil benchmark prices and weaker SYN-WTI differentials, partially offset by narrower heavy crude oil differentials.

Royalties

Royalties for the Oil Sands segment decreased in the fourth quarter of 2025 compared to the prior year quarter, primarily due to lower bitumen pricing.

Expenses and Other Factors

Total Oil Sands operating expenses increased in the fourth quarter of 2025 compared to the prior year quarter, primarily due to higher commodity input costs and volumes, increased production and increased sales volumes.

Depreciation, depletion and amortization (DD&A) expense decreased in the fourth quarter of 2025 compared to the prior year quarter, primarily due to decreased depreciation related to the company’s asset retirement obligation assets, partially offset by the commissioning of new assets and new leases entered into during the quarter.

Transportation costs decreased in the fourth quarter of 2025 compared to the prior year quarter, primarily due to decreased exports to the U.S. Gulf Coast.

Financing expense and other, which includes other income, decreased in the fourth quarter of 2025 compared to the prior year quarter, primarily due to an increase in other income.

(1)Oil Sands inventory changes and internal transfers are presented on an aggregate basis and reflect: i) the impacts of changes in inventory levels and valuations, such that the company is able to present cost information based on production volumes; and ii) adjustments for internal diesel sales between assets. In the fourth quarter and twelve months ended December 31, 2025, Oil Sands OS&G included ($75) million and ($410) million, respectively, of inventory changes and internal transfers. In the fourth quarter and twelve months ended December 31, 2024, Oil Sands OS&G included ($64) million and ($288) million, respectively, of inventory changes and internal transfers.
(2)Non-GAAP financial measures. Related per barrel amounts contain non-GAAP financial measures. See the Non-GAAP and Other Financial Measures Advisory section of this document.
(3)Non-production costs include, but are not limited to, share-based compensation adjustments, research costs, project startup costs and adjustments to reflect the cost of internal transfers in the receiving asset at the cost of production versus the cost of purchase. Non-production costs at Fort Hills and Syncrude also include, but are not limited to, an adjustment to reflect internally produced diesel from Oil Sands operations at the cost of production.
(4)Represents excess power revenue from cogeneration units that is recorded in operating revenues. Oil Sands operations excess power capacity and other also includes, but is not limited to, the natural gas expense recorded as part of a non-monetary arrangement involving a third-party processor.

Oil Sands operations cash operating costs per barrel(1) decreased to $25.90 in the fourth quarter of 2025, compared to $26.55 in the prior year quarter, primarily due to increased power sales volumes and a lower proportion of Fort Hills bitumen being directed to upgrading at Oil Sands Base, partially offset by higher natural gas volumes related to increased consumption at the new co-generation facility, higher natural gas prices and decreased production volumes.

Fort Hills cash operating costs per barrel(1) decreased to $31.60 in the fourth quarter of 2025, compared to $34.25 in the prior year quarter, primarily due to increased production volumes, partially offset by increased commodity input costs and increased mining activities.

Syncrude cash operating costs per barrel(1) decreased to $31.05 in the fourth quarter of 2025, compared to $32.80 in the prior year quarter, primarily due to increased production volumes and a lower proportion of Oil Sands Base sour SCO and Firebag bitumen being directed to upgrading at Syncrude, partially offset by increased commodity input costs.

(1)During the second quarter of 2025, Suncor recorded a write-down of an equity investment of $41 million.
(2)Non-GAAP financial measures. See the Non-GAAP and Other Financial Measures Advisory section of this document.

R&M adjusted operating earnings in the fourth quarter of 2025 increased to $893 million, compared to $410 million in the prior year quarter. The increase in adjusted operating earnings was primarily due to higher benchmark crack spreads and increased refinery production, partially offset by an increased first-in, first-out (FIFO) inventory valuation loss in the fourth quarter of 2025 compared to the prior year quarter.

18  ​ ​2025 Fourth Quarter Suncor Energy Inc.


Refining throughput increased to a quarterly record of 504,200 bbls/d with refinery utilization of 108%, compared to 486,200 bbls/d and 104%, respectively in the prior year quarter. The increase was primarily due to continued strong operating performance through the current quarter, which saw all four refineries exceed 100% utilization.

Refined product sales increased to a fourth quarter record of 640,400 bbls/d, compared to 613,300 bbls/d in the prior year quarter, primarily due to higher refinery production and continued investment in retail growth, as well as leveraging strategic partnerships.

Refining and Marketing Gross Margins(1)

Refining and marketing gross margins were influenced by the following:

On a LIFO(2) basis, Suncor’s refining and marketing gross margin increased to $45.15/bbl in the fourth quarter of 2025, from $30.60/bbl in the prior year quarter, primarily due to higher benchmark crack spreads and higher location differentials associated with the company’s regional markets. Margin capture(1) was 101% compared to Suncor’s 5-2-2-1 index in the fourth quarter of 2025.
On a FIFO basis, Suncor’s refining and marketing gross margin increased to $40.75/bbl in the fourth quarter of 2025, from $30.00/bbl in the prior year quarter, due to the same factors discussed above, in addition to FIFO inventory valuation impacts. In the fourth quarter of 2025, the FIFO method of inventory valuation resulted in a loss of $215 million compared to a loss of $29 million in the prior year quarter, for an unfavourable quarter-over-quarter impact of $186 million.

Expenses and Other Factors

Operating expenses in fourth quarter of 2025 were comparable to the prior year quarter, as lower maintenance costs offset higher commodity input costs. Transportation expenses increased compared to the prior year quarter, primarily due to increased production and sales volumes.

Refining operating expense per barrel(1) of $6.55 in the fourth quarter of 2025 was comparable to $6.55 in the prior year quarter, as increased refinery production offset higher commodity input costs.

Planned Maintenance

The anticipated impact of these significant maintenance activities has been reflected in the company’s 2026 guidance.

Planned maintenance at the Commerce City refinery is commencing in the first quarter of 2026, with completion expected in the second quarter of 2026.

The estimated impact of the LIFO method is a non-GAAP financial measure. The impact of the FIFO method of inventory valuation, relative to an estimated LIFO accounting method, also includes the impact of the realized portion of commodity risk management activities.

(1)During the second quarter of 2025, Suncor recorded a write-down of an equity investment of $95 million.
(2)Non-GAAP financial measures. See the Non-GAAP and Other Financial Measures Advisory section of this document.

Corporate incurred an adjusted operating loss of $307 million in the fourth quarter of 2025, compared to an adjusted operating loss of $92 million in the prior year quarter. The increased loss was primarily attributable to an operational foreign exchange loss in the current quarter compared to a gain in the prior year quarter, partially offset by a decrease in share-based compensation expense in the current quarter compared to the prior year quarter.

Eliminations reflect the deferral or realization of profit or loss on crude oil sales from Oil Sands to Suncor’s refineries. Consolidated profits and losses are only realized when the refined products from internal purchases have been sold to third parties. During the fourth quarter of 2025, the company realized $58 million of intersegment profit compared to a deferral of $108 million in the prior year quarter. The realization of intersegment profit in the fourth quarter of 2025 was primarily driven by lower refinery feedstock costs in the quarter.

Corporate and Eliminations adjusted funds used in operations were $108 million for the fourth quarter of 2025, compared to adjusted funds used in operations of $131 million in the prior year quarter, and were influenced by the same factors impacting adjusted operating loss, excluding the impact of share-based compensation expense.

Capital Resources

Suncor’s capital resources consist primarily of cash flow provided by operating activities, cash and cash equivalents, and available lines of credit. Suncor’s management believes the company will have the capital resources required to fund its planned 2026 capital spending program of $5.6 billion to $5.8 billion, and to meet working capital requirements, through cash and cash equivalents balances, cash flow provided by operating activities, available committed credit facilities, issuing commercial paper and, if needed, accessing capital markets. The company’s cash flow provided by operating activities depends on several factors, including commodity prices, production, sales volumes, refining and marketing gross margins, operating expenses, taxes, royalties and foreign exchange rates.

The company has invested cash in short-term financial instruments that are presented as cash and cash equivalents. The objectives of the company’s short-term investment portfolio are to ensure the preservation of capital, maintain adequate liquidity to meet Suncor’s cash flow requirements, and deliver competitive returns derived from the quality and diversification of investments within acceptable risk parameters. The maximum weighted average term to maturity of the short-term investment portfolio is not expected to exceed six months, and all investments are with counterparties with investment-grade debt ratings.

Available Sources of Liquidity

For the three months ended December 31, 2025, cash and cash equivalents increased to $3.650 billion from $2.944 billion as at September 30, 2025. The source of cash in the fourth quarter of 2025 was primarily due to the company’s cash flow provided by operating activities exceeding the company’s shareholder returns, including the repurchase of Suncor’s common shares under its normal course issuer bid (NCIB) and the payment of dividends, and the company’s capital expenditures.

For the twelve months ended December 31, 2025, cash and cash equivalents increased to $3.650 billion from $3.484 billion as at December 31, 2024. The source of cash in 2025 was primarily due to the company’s cash flow provided by operating activities exceeding the company’s capital expenditures and shareholder returns, including the repurchase of Suncor’s common shares under its NCIB and the payment of dividends.

As at December 31, 2025, the weighted average days to maturity of the company’s short-term investment portfolio was approximately 12 days.

As at December 31, 2025, available credit facilities for liquidity purposes were $5.219 billion, compared to $5.475 billion as at December 31, 2024.

In the fourth quarter of 2025, the company extended the maturity of its syndicated credit facilities from October 2027 and October 2028 to December 2028 and December 2029, respectively.

Financing Activities

Management of debt levels and liquidity continues to be a priority for Suncor given the company’s long-term plans and the expected future volatility in the business environment. Suncor believes a phased and flexible approach to existing and future projects will help the company maintain its ability to manage project costs and debt levels.

Total Debt to Total Debt Plus Shareholders’ Equity

Suncor is subject to financial and operating covenants related to its bank debt and public market debt. Failure to meet the terms of one or more of these covenants may constitute an “event of default” as defined in the respective debt agreements, potentially resulting in accelerated repayment of one or more of the debt obligations. The company is in compliance with its financial covenant that requires total debt and lease liabilities to not exceed 65% of its total debt and lease liabilities plus shareholders’ equity. As at December 31, 2025, total debt and lease liabilities to total debt and lease liabilities plus shareholders’ equity was 24.3% (December 31, 2024 – 24.8%). The company also continues to be in compliance with all operating covenants under its debt agreements.

The company’s total debt decreased in 2025, primarily due to favourable foreign exchange rates on U.S. dollar denominated debt compared to December 31, 2024.

In the fourth quarter of 2025, the company issued $1.0 billion in aggregate principal of senior unsecured notes, consisting of $500 million principal amount of Series 11 Medium Term Notes due on November 14, 2027, having a coupon of 2.95% and $500 million principal amount of Series 12 Medium Term Notes due on November 14, 2030, having a coupon of 3.55%. Debt issuance costs were $4 million and were netted against the carrying amount of the debt and amortized using the effective interest method. Net proceeds of approximately $1 billion from the issuance were utilized to repay the 5.60% Series 9 Medium Term Notes, due 2025, with a principal amount of $1 billion.

As at December 31, 2025, Suncor’s net debt was $6.337 billion, compared to $6.861 billion as at December 31, 2024. The decrease in net debt was primarily due to an increase in cash and cash equivalents and the factors discussed above.

Suncor’s current NCIB will terminate on March 2, 2026. The company intends to renew the NCIB program subsequent to the expiration of its current NCIB.

Between March 3, 2025 and January 30, 2026, pursuant to Suncor’s current NCIB, Suncor repurchased 50,474,677 common shares on the open market, representing the equivalent of 4.1% of its common shares as at February 18, 2025, for $2.8 billion, at a weighted average price of $55.46 per common share.

The actual number of common shares that may be repurchased under the NCIB and the timing of any such repurchases will be determined by Suncor. The company believes that, depending on the trading price of its common shares and other relevant factors, repurchasing its own shares represents an attractive investment opportunity and is in the best interests of the company and its shareholders. The company does not expect that the decision to allocate cash to repurchase shares will affect its long-term strategy.

8. Other Items

Accounting Policies and New IFRS Standards

Suncor’s significant accounting policies and a summary of recently announced accounting standards are described in the Accounting Policies and Critical Accounting Estimates section of Suncor’s 2024 annual MD&A and in notes 3 and 5 of Suncor’s audited Consolidated Financial Statements for the year ended December 31, 2024.

Critical Accounting Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates, judgments and assumptions that affect reported assets, liabilities, revenues and expenses, gains and losses, and disclosures of contingencies. These estimates and assumptions are subject to change based on experience and new information. Critical accounting estimates are those that require management to make assumptions about matters that are highly uncertain at the time the estimate is made. Critical accounting estimates are also those estimates that, where a different estimate could have been used or where changes in the estimate that are reasonably likely to occur, would have a material impact on the company’s financial condition, changes in financial condition or financial performance. Critical accounting estimates and judgments are reviewed annually by the Audit Committee of the Board of Directors. A detailed description of Suncor’s critical accounting estimates is provided in note 4 to the audited Consolidated Financial Statements for the year ended December 31, 2024, and in the Accounting Policies and Critical Accounting Estimates section of Suncor’s 2024 annual MD&A.

Financial Instruments

Suncor periodically enters into derivative contracts such as forwards, futures, swaps, options and costless collars to manage exposure to fluctuations in commodity prices and foreign exchange rates, and to optimize the company’s position with respect to interest payments. For more information on Suncor’s financial instruments and the related financial risk factors, see note 27 of the audited Consolidated Financial Statements for the year ended December 31, 2024, note 9 to the unaudited interim Consolidated Financial Statements for the twelve months ended December 31, 2025, and the Financial Condition and Liquidity section of the 2024 annual MD&A.

Tariffs

The government of the United States of America has continued to either implement or propose tariffs on various Canadian products. The company is closely monitoring these developments and will continue to assess the impacts of such tariffs and measures as the situation develops. To date, the implemented and proposed tariff changes have not had a material impact to the company’s input costs. The impact of potential future tariffs on the company’s financial results is subject to significant uncertainty, as such the impact cannot be quantified at this time.

9. Non-GAAP and Other Financial Measures Advisory

Certain financial measures in this document – namely adjusted operating earnings (loss), adjusted funds from (used in) operations, measures contained in ROCE and ROCE excluding impairments and impairment reversals, price realizations, free funds flow (deficit), normalized free funds flow, Oil Sands operations cash operating costs, Fort Hills cash operating costs, Syncrude cash operating costs, refining and marketing gross margin, refining operating expense, refining and marketing margin capture, net debt, total debt, LIFO inventory valuation methodology and related per share or per barrel amounts or metrics that contain such measures – are not prescribed by GAAP. These non-GAAP financial measures are included because management uses the information to analyze business performance, leverage and liquidity, as applicable, and it may be useful to investors on the same basis. 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. Except as otherwise indicated, these non-GAAP financial measures are calculated and disclosed on a consistent basis from period to period. Specific adjusting items may only be relevant in certain periods.

Adjusted Operating Earnings (Loss)

Adjusted operating earnings (loss) is a non-GAAP financial measure that adjusts net earnings (loss) for significant items that are not indicative of operating performance. Management uses adjusted operating earnings (loss) to evaluate operating performance because management believes it provides better comparability between periods. Adjusted operating earnings (loss) is reconciled to net earnings (loss) in the Consolidated Financial and Operating Information and Segment Results and Analysis sections of this document.

Bridge Analyses of Adjusted Operating Earnings (Loss)

Within this document, the company presents a chart that illustrates the change in adjusted operating earnings (loss) from the comparative period through key variance factors. These factors are analyzed in the Adjusted Operating Earnings (Loss) narratives following the bridge analysis in this document. This bridge analysis is presented because management uses this presentation to evaluate performance. All reconciling items are presented on a before-tax basis and adjusted for income taxes in the Income Tax bridge factor.

The factor for Sales Volumes and Mix is calculated based on sales volumes and mix for the Oil Sands and E&P segments and refinery production volumes for the R&M segment.
The factor for Price, Margin and Other Revenue includes upstream price realizations before royalties, except for the company’s Libya operations, which is net of royalties, and realized commodity risk management activities. Also included are refining and marketing gross margins, other operating revenue and the net impacts of sales and purchases of third-party crude, including product purchased for use as diluent in the company’s Oil Sands operations and subsequently sold as part of diluted bitumen.
The factor for Royalties excludes the impact of the company’s Libya operations, as royalties in Libya are included in Price, Margin and Other Revenue as described above.
The factor for Inventory Valuation is comprised of changes in the FIFO inventory valuation and the realized portion of commodity risk management activities reported in the R&M segment, as well as the impact of the deferral or realization of profit or loss on crude oil sales from the Oil Sands segment to Suncor’s refineries reported in the Corporate and Eliminations segment.
The factor for Operating and Transportation Expense includes project startup costs, OS&G expense and transportation expense.
The factor for Financing Expense and Other includes financing expenses, other income, operational foreign exchange gains and losses and changes in gains and losses on disposal of assets that are not adjusted operating earnings (loss) adjustments.
The factor for DD&A and Exploration Expense includes depreciation, depletion and amortization expense, and exploration expense.
The factor for Income Tax includes the company’s current and deferred income tax expense on adjusted operating earnings, changes in statutory income tax rates and other income tax adjustments.

Fourth Quarter Discussion

ROCE and ROCE Excluding Impairments and Impairment Reversals

ROCE is a non-GAAP ratio that management uses to analyze operating performance and the efficiency of Suncor’s capital allocation process. ROCE is calculated using the non-GAAP financial measures adjusted net earnings and average capital employed. Adjusted net earnings are calculated by taking net earnings (loss) and adjusting after-tax amounts for unrealized foreign exchange on U.S. dollar denominated debt and net interest expense. Average capital employed is calculated as a twelve-month average of the capital employed balance at the beginning of the twelve-month period and the month-end capital employed balances throughout the remainder of the twelve-month period. Figures for capital employed at the beginning and end of the twelve-month period are presented to show the changes in the components of the calculation over the twelve-month period.

Adjusted Funds From (Used In) Operations

Adjusted funds from (used in) operations is a non-GAAP financial measure that adjusts a GAAP measure – cash flow provided by operating activities – for changes in non-cash working capital, which management uses to analyze operating performance and liquidity. Changes to non-cash working capital can be impacted by, among other factors, commodity price volatility, the timing of offshore feedstock purchases and payments for commodity and income taxes, the timing of cash flows related to accounts receivable and accounts payable, and changes in inventory, which management believes reduces comparability between periods.

Adjusted funds from (used in) operations for each quarter are separately defined and reconciled to the cash flow provided by the operating activities measure in the Non-GAAP and Other Financial Measures Advisory section of each respective MD&A or Quarterly Report to shareholders, as applicable, for the related quarter, with such information being incorporated by reference herein and available on SEDAR+ at www.sedarplus.ca.

Oil Sands Operations, Fort Hills and Syncrude Cash Operating Costs

Cash operating costs are calculated by adjusting Oil Sands segment OS&G expenses for non-production costs and excess power capacity. Significant non-production costs include, but are not limited to, share-based compensation adjustments, research costs, project startup costs and adjustments to reflect the cost of internal transfers in the receiving asset at the cost of production versus the cost of purchase. Non-production costs at Fort Hills and Syncrude also include, but are not limited to, an adjustment to reflect internally produced diesel from Oil Sands operations at the cost of production. Excess power capacity represents excess power revenue from cogeneration units that is recorded in operating revenues. Oil Sands operations excess power capacity and other also includes, but is not limited to, the natural gas expense recorded as part of a non-monetary arrangement involving a third-party processor. Oil Sands operations, Fort Hills and Syncrude production volumes are gross of internally consumed diesel and feedstock transfers between assets. Oil Sands operations, Fort Hills and Syncrude cash operating costs are reconciled in the Segment Results and Analysis – Oil Sands – Cash Operating Costs section of this document. Management uses cash operating costs to measure operating performance.

Refining and Marketing Gross Margin, Margin Capture and Refining Operating Expense

Refining and marketing gross margins, refining and marketing margin capture and refining operating expense are non-GAAP financial measures. Refining and marketing gross margin, on a FIFO basis, is calculated by adjusting R&M segment operating revenue, other income and purchases of crude oil and products (all of which are GAAP measures) for intersegment marketing fees recorded in intersegment revenues. Refining and marketing gross margin, on a LIFO basis, is further adjusted for the impacts of FIFO inventory valuation recorded in purchases of crude oil and products and risk management activities recorded in other income (loss). Refinery operating expense is calculated by adjusting R&M segment OS&G expenses for i) non-refining costs pertaining to the company’s supply, marketing and ethanol businesses; and ii) non-refining costs that management believes do not relate to the production of refined products, including, but not limited to, share-based compensation and enterprise shared service allocations. Refining and marketing margin capture is calculated by dividing refining and marketing gross margin, on a LIFO basis, by the Suncor custom 5-2-2-1 index. For details on how the 5-2-2-1 index is calculated, see Suncor’s 2024 annual MD&A. Management uses refining and marketing gross margin, refining operating expense and refining and marketing margin capture to measure operating performance on a production barrel basis.

Fourth Quarter Discussion

Impact of FIFO Inventory Valuation on Refining and Marketing Net Earnings (Loss)

GAAP requires the use of a FIFO inventory valuation methodology. For Suncor, this results in a disconnect between the sales prices for refined products, which reflect current market conditions, and the amount recorded as the cost of sale for the related refinery feedstock, which reflects market conditions at the time the feedstock was purchased. This lag between purchase and sale can be anywhere from several weeks to several months and is influenced by the time to receive crude after purchase, regional crude inventory levels, the completion of refining processes, transportation time to distribution channels and regional refined product inventory levels.

Suncor prepares and presents an estimate of the impact of using a FIFO inventory valuation methodology compared to a LIFO methodology, because management uses the information to analyze operating performance and compare itself against refining peers that are permitted to use LIFO inventory valuation under U.S. GAAP.

The company’s estimate is not derived from a standardized calculation and, therefore, may not be directly comparable to similar measures presented by other companies, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP or U.S. GAAP.

Net Debt and Total Debt

Net debt and total debt are non-GAAP financial measures that management uses to analyze the financial condition of the company. Total debt includes short-term debt, current portion of long-term debt and long-term debt (all of which are GAAP measures). Net debt is equal to total debt less cash and cash equivalents (a GAAP measure).

All statements and information that address expectations or projections about the future, and other 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 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”, “future”, “potential”, “opportunity”, “would”, “priority”, “strategy” and similar expressions. Forward-looking statements in this document include references to:

Suncor’s belief that it will deliver superior shareholder value and resilient cash flows and the basis for such belief;
the expectation that Suncor will continue to return 100% of excess funds to shareholders in 2026;
Suncor’s projection of $3.3 billion of share repurchases in 2026;
the anticipated duration and impact of planned maintenance events, including the planned maintenance at the Commerce City refinery, Firebag, Oil Sands Base and Syncrude that is commencing in the first quarter of 2026;
the expected benefits of asset sustainment and maintenance capital expenditures and economic investment capital expenditures;
Suncor’s expectation that In Situ design and construction of new well pads will maintain existing production levels;
statements regarding Suncor’s planned 2026 capital spending program of $5.6 billion to $5.8 billion, including Suncor’s management’s belief that it will have the capital resources to fund it and to meet working capital requirements through cash and cash equivalents balances, cash flow provided by operating activities, available committed credit facilities, issuing commercial paper and, if needed, accessing capital markets;
the objectives of Suncor’s short-term investment portfolio and Suncor’s expectation that the maximum weighted average term to maturity of the short-term investment portfolio will not exceed six months, and that all investments will be with counterparties with investment-grade debt ratings;
the company’s priority regarding the management of debt levels and liquidity given the company’s long-term plans and future expected volatility in the pricing environment, and Suncor’s belief that a phased and flexible approach to existing and future projects will help the company manage project costs and debt levels;
statements about the company’s NCIB, including the expectation that the company intends to renew the NCIB program subsequent to the expiration of its current NCIB, its belief that belief that, depending on the trading price of its common shares and other relevant factors, that repurchasing its own shares represents an attractive investment opportunity and is in the best interests of the company and its shareholders and its expectation that its decision to allocate cash to repurchase shares will not affect its long-term strategy; and
the company’s belief that it does not have any guarantees or off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on the company’s financial performance or financial condition, results of operations, liquidity or capital expenditures.

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. The financial and operating performance of the company’s reportable operating segments, specifically Oil Sands, E&P and R&M, may be affected by a number of factors.

Factors that affect Suncor’s Oil Sands segment include, but are not limited to, volatility in the prices for crude oil and other production, and the related impacts of fluctuating light/heavy and sweet/sour crude oil differentials; changes in the demand for refinery feedstock and diesel fuel, including the possibility that refiners that process the company’s proprietary production will be closed, experience equipment failure or other accidents; Suncor’s ability to operate its Oil Sands facilities reliably in order to meet production targets; the output of newly commissioned facilities, the performance of which may be difficult to predict during initial operations; Suncor’s dependence on pipeline capacity and other logistical constraints, which may affect the company’s ability to distribute products to market and which may cause the company to delay or cancel planned growth projects in the event of insufficient takeaway capacity; Suncor’s ability to finance Oil Sands economic investment and asset sustainment and maintenance capital expenditures; the availability of bitumen feedstock for upgrading operations, which can be negatively affected by poor ore grade quality, unplanned mine equipment and extraction plant maintenance, tailings storage, and In Situ reservoir and equipment performance, or the unavailability of third-party bitumen; changes in operating costs, including the cost of labour, natural gas and other energy sources used in oil sands processes; and the company’s ability to complete projects, including planned maintenance events, both on time and on budget, which could be impacted by competition from other projects (including other oil sands projects) for goods and services and demands on infrastructure in Alberta’s Wood Buffalo region and the surrounding area (including housing, roads and schools).

Factors that affect Suncor’s E&P segment include, but are not limited to, volatility in crude oil and natural gas prices; operational risks and uncertainties associated with oil and gas activities, including unexpected formations or pressures, premature declines of reservoirs, fires, blow-outs, equipment failures and other accidents, uncontrollable flows of crude oil, natural gas or well fluids, and pollution and other environmental risks; adverse weather conditions, which could disrupt output from producing assets or impact drilling programs, resulting in increased costs and/or delays in bringing on new production; political, economic and socioeconomic risks associated with Suncor’s foreign operations, including the unpredictability of operating in Libya due to ongoing political unrest; and market demand for mineral rights and producing properties, potentially leading to losses on disposition or increased property acquisition costs.

38  ​ ​2025 Fourth Quarter Suncor Energy Inc.


Factors that affect the R&M segment include, but are not limited to, fluctuations in demand and supply for refined products that impact the company’s margins; market competition, including potential new market entrants; the company’s ability to reliably operate refining and marketing facilities to meet production or sales targets; and risks and uncertainties affecting construction or planned maintenance schedules, including the availability of labour and other impacts of competing projects drawing on the same resources during the same time period.

Additional 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 commodity prices, interest rates, currency exchange rates and potential trade tariffs (including as a result of demand and supply effects resulting from the actions of OPEC+ and/or the impact of armed conflicts in the Middle East, the impact of the Russian invasion of Ukraine and/or the impact of changes to the U.S. government economic policy); fluctuations in supply and demand for Suncor’s products; the successful and timely implementation of capital projects, including growth projects and regulatory projects; risks associated with the development and execution of Suncor’s major projects and the commissioning and integration of new facilities; the possibility that completed maintenance activities may not improve operational performance or the output of related facilities; the risk that projects and initiatives intended to achieve cash flow growth and/or reductions in operating costs may not achieve the expected results in the time anticipated or at all; competitive actions of other companies, including increased competition from other oil and gas companies or from companies that provide alternative sources of energy; labour and material shortages; actions by government authorities, including the imposition or reassessment of, or changes to, taxes, fees, royalties, duties and other government-imposed compliance costs; changes to laws and government policies that could impact the company’s business, including environmental (including climate change), royalty and tax laws and policies; the ability and willingness of parties with whom Suncor has material relationships to perform their obligations to the company; the unavailability of, or outages to, third-party infrastructure that could cause disruptions to production or prevent the company from being able to transport its products; the occurrence of a protracted operational outage, a major safety or environmental incident, or unexpected events such as fires (including forest fires), equipment failures and other similar events affecting Suncor or other parties whose operations or assets directly or indirectly affect Suncor; the potential for security breaches of Suncor’s information technology and infrastructure by malicious persons or entities, and the unavailability or failure of such systems to perform as anticipated as a result of such breaches; security threats and terrorist or activist activities; the risk that competing business objectives may exceed Suncor’s capacity to adopt and implement change; risks and uncertainties associated with obtaining regulatory, third-party and stakeholder approvals outside of Suncor’s control for the company’s operations, projects, initiatives and exploration and development activities and the satisfaction of any conditions to approvals; the potential for disruptions to operations and construction projects as a result of Suncor’s relationships with labour unions that represent employees at the company’s facilities; the company’s ability to find new oil and gas reserves that can be developed economically; the accuracy of Suncor’s reserves, resources and future production estimates; market instability affecting Suncor’s ability to borrow in the capital debt markets at acceptable rates or to issue other securities at acceptable prices; the ability to maintain an optimal debt to cash flow ratio; the success of the company’s marketing and logistics activities using derivatives and other financial instruments; the cost of compliance with current and future environmental laws, including climate change laws; risks relating to increased activism and public opposition to fossil fuels and oil sands; the ability of counterparties to comply with their obligations in a timely manner; risks associated with joint arrangements in which the company has an interest; risks associated with land claims and Indigenous consultation requirements; the risk that the company may be subject to litigation; the impact of technology and risks associated with developing and implementing new technologies; and the accuracy of cost estimates, some of which are provided at the conceptual or other preliminary stage of projects and prior to commencement or conception of the detailed engineering that is needed to reduce the margin of error and increase the level of accuracy. 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 throughout this document, and in the company’s 2024 annual MD&A, the 2024 AIF and Form 40-F on file with Canadian securities commissions at www.sedarplus.ca and the United States Securities and Exchange Commission at www.sec.gov. Readers are also referred to the risk factors and assumptions described in other MD&As that Suncor files from time to time with securities regulatory authorities. Copies of these MD&As are available without charge from the company.

The forward-looking statements contained in this document are made as of the date of this document. 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.

Notes to the Consolidated Financial Statements

(unaudited)

1. Reporting Entity and Description Of The Business

Suncor Energy is Canada’s leading integrated energy company. Suncor’s operations include oil sands development, production and upgrading; offshore oil production; petroleum refining in Canada and the U.S.; and the company’s Petro-Canada™ retail and wholesale distribution networks (including Canada’s Electric Highway™, a coast-to-coast network of fast-charging EV stations). Suncor is developing petroleum resources while advancing the transition to a lower-emissions future through investments in lower emissions intensity power, renewable feedstock fuels and projects targeting emissions intensity. Suncor also conducts energy trading activities focused primarily on the marketing and trading of crude oil, natural gas, byproducts, refined products and power. Suncor’s common shares (symbol: SU) are listed on the TSX and NYSE.

The address of the company’s registered office is 150 – 6th Avenue S.W., Calgary, Alberta, Canada, T2P 3E3.

2. Basis of Preparation

(a) Statement of Compliance

These condensed interim consolidated financial statements are based on International Financial Reporting Standards as issued by the International Accounting Standards Board (the “IFRS Accounting Standards”) and have been prepared in accordance with International Accounting Standard 34 Interim Financial Reporting. They are condensed as they do not include all of the information required for full annual financial statements, and they should be read in conjunction with the audited consolidated financial statements of the company for the year ended December 31, 2024.

(b) Basis of Measurement

The consolidated financial statements are prepared on a historical cost basis except as detailed in the accounting policies disclosed in the company’s audited consolidated financial statements for the year ended December 31, 2024.

(c) Functional Currency and Presentation Currency

These consolidated financial statements are presented in Canadian dollars, which is the company’s functional currency.

(d) Use of Estimates, Assumptions and Judgments

The timely preparation of financial statements requires that management make estimates and assumptions and use judgment. Accordingly, actual results may differ from estimated amounts as future confirming events occur. Significant estimates and judgment used in the preparation of the financial statements are described in the company’s audited consolidated financial statements for the year ended December 31, 2024.

The government of the United States of America has continued to either implement or propose tariffs on various Canadian products. The company is closely monitoring these developments and will continue to assess the impacts of such tariffs and measures as the situation develops. To date, the implemented and proposed tariff changes have not had a material impact to the company’s input costs. The impact of potential future tariffs on the company’s financial results is subject to significant uncertainty, as such the impact cannot be quantified at this time.     

(e) Income Taxes

The company recognizes the impacts of income tax rate changes in earnings in the period that the applicable rate change is enacted or substantively enacted.

44  ​ ​2025 Fourth Quarter   Suncor Energy Inc.


3. Segmented Information

The company’s operating segments are reported based on the nature of their products and services and management responsibility.

Intersegment sales of crude oil are accounted for at market values and are included, for segmented reporting, in revenues of the segment making the transfer and expenses of the segment receiving the transfer. Intersegment amounts are eliminated on consolidation.

In the fourth quarter of 2025, the company extended the maturity of its syndicated credit facilities from October 2027 and October 2028, to December 2028 and December 2029, respectively.

In the fourth quarter of 2025, the company issued $1.0 billion in aggregate principal of senior unsecured notes, consisting of $500 million principal amount of Series 11 Medium Term Notes due on November 14, 2027, having a coupon of 2.95% and $500 million principal amount of Series 12 Medium Term Notes due on November 14, 2030, having a coupon of 3.55%. Debt issuance costs were $4 million and were netted against the

48  ​ ​2025 Fourth Quarter   Suncor Energy Inc.


carrying amount of the debt and amortized using the effective interest method. Net proceeds of approximately $1 billion from the issuance were utilized to repay the 5.60% Series 9 Medium Term Notes, due 2025, with a principal amount of $1 billion.

In the fourth quarter of 2024, the company extended the maturity of its syndicated credit facilities from June 2026 to October 2027 and October 2028.

In the fourth quarter of 2024, the company executed a debt tender offer pursuant to which it repaid $1.1 billion CAD equivalent aggregate principal amount of debt above par plus accrued and unpaid interest of $24 million. As a result of the extinguishment, the company incurred charges of $168 million related to accelerated amortization of debt issuance fees. This resulted in a total loss on extinguishment of long-term debt of $144 million ($111 million after tax). The general terms of the notes that were extinguished are as follows:

3.00% Series 5 Medium Term Notes, due 2026, with a principal amount of $115 million (partial repayment of $20 million);
3.10% Series 6 Medium Term Notes, due 2029, with a principal amount of $79 million (partial repayment of $13 million);
5.35% Notes, due 2033, with a principal amount of US$118 million (partial repayment of US$28 million);
5.95% Notes, due 2035, with a principal amount of US$199 million (partial repayment of US$22 million);
6.50% Notes, due 2038, with a principal amount of US$954 million (partial repayment of US$479 million); and
6.80% Notes, due 2038, with a principal amount of US$881 million (partial repayment of US$260 million).

In the third quarter of 2024, the company completed two partial redemptions, resulting in a debt extinguishment loss of $26 million ($23 million after tax). The general terms of the notes that were extinguished are as follows:

6.50% Notes, due 2038, with a principal amount of US$1.15 billion (partial repayment of US$196 million); and
6.80% Notes, due 2038, with a principal amount of US$900.0 million (partial repayment of US$19 million).

9. Financial Instruments

Derivative Financial Instruments

(a) Non-Designated Derivative Financial Instruments

The company uses derivative financial instruments, such as physical and financial contracts, to manage certain exposures to fluctuations in interest rates, commodity prices and foreign currency exchange rates, as part of its overall risk management program, as well as for trading purposes.

The changes in the fair value of non-designated derivatives are as follows:

(b) Fair Value Hierarchy

To estimate the fair value of derivatives, the company uses quoted market prices when available, or third-party models and valuation methodologies that utilize observable market data. In addition to market information, the company incorporates transaction-specific details that market participants would utilize in a fair value measurement, including the impact of non-performance risk. However, these fair value estimates may not necessarily be indicative of the amounts that could be realized or settled in a current market transaction. The company characterizes inputs used in determining fair value using a hierarchy that prioritizes inputs depending on the degree to which they are observable. The three levels of the fair value hierarchy are as follows:

Level 1 consists of instruments with a fair value determined by an unadjusted quoted price in an active market for identical assets or liabilities. An active market is characterized by readily and regularly available quoted prices where the prices are representative of actual and regularly occurring market transactions to assure liquidity.
Level 2 consists of instruments with a fair value that is determined by quoted prices in an inactive market, prices with observable inputs or prices with insignificant non-observable inputs. The fair value of these positions is determined using observable inputs from exchanges, pricing services, third-party independent broker quotes and published transportation tolls. The observable inputs may be adjusted using certain methods, which include extrapolation over the quoted price term and quotes for comparable assets and liabilities.
Level 3 consists of instruments with a fair value that is determined by prices with significant unobservable inputs. As at December 31, 2025, the company does not have any derivative instruments measured at fair value Level 3.

In forming estimates, the company utilizes the most observable inputs available for valuation purposes. If a fair value measurement reflects inputs of different levels within the hierarchy, the measurement is categorized based upon the lowest level of input that is significant to the fair value measurement.

The following table presents the company’s derivative financial instruments measured at fair value for each hierarchy level as at December 31, 2025:

During the fourth quarter of 2025, there were no transfers between Level 1 and Level 2 fair value measurements.

Non-Derivative Financial Instruments

At December 31, 2025, the carrying value of fixed-term debt accounted for under amortized cost was $10.0 billion (December 31, 2024 – $10.3 billion) and the fair value was $9.8 billion (December 31, 2024 – $10.1 billion). The estimated fair value of long-term debt is based on pricing sourced from market data.

10. Provisions

Suncor’s decommissioning and restoration provision increased by $350 million for the twelve months ended December 31, 2025. The increase was primarily due to an increase in the decommissioning cost estimate partially offset by an increase in the credit-adjusted risk-free rate to 5.0% (December 31, 2024 – 4.80%).

11. Pensions and Other Post-Retirement Benefits

For the twelve months ended December 31, 2025, the actuarial gain on employee retirement benefit plans was $596 million (net of taxes of $187 million), due to asset performance and an increase in the discount rate to 4.90% (December 31, 2024 – 4.60%).

Operating Summary Information

Non-GAAP and Other Financial Measures

Certain financial measures in this Supplemental Financial and Operating Information – namely adjusted operating earnings (loss), adjusted funds from (used in) operations, free funds flow, measures contained in return on capital employed (ROCE), Oil Sands operations cash operating costs, Fort Hills cash operating costs, Syncrude cash operating costs, refining and marketing gross margin, rack forward gross margin, refining operating expense, rack forward operating expense and, refining and marketing margin capture and operating netbacks – are not prescribed by generally accepted accounting principles (GAAP). Suncor uses this information to analyze business performance, leverage and liquidity and includes these financial measures because investors may find such measures useful on the same basis. 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. The additional information should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.

Adjusted operating earnings (loss), Oil Sands operations cash operating costs, Fort Hills cash operating costs and Syncrude cash operating costs are defined in the Non-GAAP and Other Financial Measures Advisory section and reconciled to GAAP measures in the Consolidated Financial Information and Segment Results and Analysis sections of each respective Quarterly Report to Shareholders in respect of the relevant quarter (Quarterly Report). Adjusted funds from (used in) operations, free funds flow and measures contained in ROCE are defined and reconciled to GAAP measures in the Non-GAAP and Other Financial Measures Advisory section of each respective Quarterly Report. Refining and marketing gross margin, refining and marketing margin capture, rack forward gross margin, refining operating expense and rack forward operating expense are defined in the Non-GAAP and Other Financial Measures Advisory section and reconciled to GAAP measures in the Quarterly Operating Metrics Reconciliation section of each respective Quarterly Report, as applicable. Operating netbacks are defined below and are reconciled to GAAP measures in the Quarterly Operating Metrics Reconciliation section of each respective Quarterly Report. The remainder of the non-GAAP financial measures not otherwise mentioned in this paragraph are defined and reconciled in this Quarterly Report.

Oil Sands Operating Netbacks

Oil Sands operating netbacks are a non-GAAP measure, presented on a crude product and sales barrel basis, and are derived from the Oil Sands segmented statement of net earnings (loss), after adjusting for items not directly attributable to the revenues and costs associated with production and delivery. Management uses Oil Sands operating netbacks to measure crude product profitability on a sales barrel basis.

Exploration and Production (E&P) Operating Netbacks

E&P operating netbacks are a non-GAAP measure, presented on an asset location and sales barrel basis, and are derived from the E&P segmented statement of net earnings (loss), after adjusting for items not directly attributable to the revenues and costs associated with production and delivery. Management uses E&P operating netbacks to measure asset profitability by location on a sales barrel basis.

Definitions

(1)Cash operating costs are calculated by adjusting Oil Sands segment operating, selling and general expense for non-production costs and excess power capacity. Significant non-production costs include, but are not limited to, share-based compensation adjustments, research costs, project startup costs and adjustments to reflect the cost of internal transfers in the receiving asset at the cost of production versus the cost of purchase. Non-production costs at Fort Hills and Syncrude also include, but are not limited to, an adjustment to reflect internally produced diesel from Oil Sands operations at the cost of production. Excess power capacity represents excess power revenue from cogeneration units that is recorded in operating revenues. Oil Sands operations excess power capacity and other also includes, but is not limited to, the natural gas expense recorded as part of a non-monetary arrangement involving a third-party processor. Oil Sands operations, Fort Hills and Syncrude production volumes are gross of internally consumed diesel and feedstock transfers between assets. Oil Sands operations, Fort Hills and Syncrude cash operating costs are reconciled in the Segment Results and Analysis – Oil Sands section of this document. Management uses cash operating costs to measure operating performance.
(2)Reflects the items not directly attributed to revenues received from the sale of proprietary crude and net non-proprietary activity at its deemed point of sale.
(3)Reflects adjustments for general and administrative costs not directly attributed to the production of each crude product type, as well as the revenues associated with excess power generated from cogeneration units and sold that is recorded in operating revenue.
(4)Reflects other E&P assets, such as Libya, for which netbacks are not provided.
(5)Production from the company’s Libya operations has been presented in this document on an economic basis. Revenue and royalties from the company’s Libya operations are presented under the working-interest basis, which is required for presentation purposes in the company’s financial statements. Under the working-interest basis, revenue includes a gross-up amount with offsetting amounts presented in royalties in the E&P segment and income tax expense reported at the total consolidated level.
(6)Reflects adjustments for general and administrative costs not directly attributed to production.
(7)Reflects adjustments for intersegment marketing fees.
(8)Refining production is the output of the refining process and differs from crude oil processed as a result of volumetric adjustment for non-crude feedstock, volumetric gain associated with the refining process and changes in unfinished product inventories.
(9)Rack forward operating revenues, other income less purchases of crude oil and products.
(10)Rack forward operating expense reflects operating, selling and general expenses associated with retail and wholesale operations.
(11)Reflects operating, selling and general expenses associated with the company’s ethanol businesses and certain general and administrative costs not directly attributable to refinery production.
(12)The custom 5-2-2-1 index is designed to represent Suncor’s Refining and Marketing business based on publicly available pricing data and approximates the gross margin on five barrels of crude oil of varying grades that is refined to produce two barrels of both gasoline and distillate and one barrel of secondary product. The index is a single value that is calculated by taking the product value of refined products less the crude value of refinery feedstock incorporating the company’s refining, product supply and rack forward businesses, but excluding the impact of first-in, first-out accounting. The product value is influenced by New York Harbor 2-1-1 crack, Chicago 2-1-1 crack, WTI benchmarks and seasonal factors. The seasonal factor is an estimate and reflects the location, quality and grade differentials for refined products sold in the company’s core markets during the winter and summer months. The crude value is influenced by SYN, WCS and WTI benchmarks.

Explanatory Notes

*Users are cautioned that the Oil Sands operations, Fort Hills and Syncrude cash operating costs per barrel measures may not be fully comparable to one another or to similar information calculated by other entities due to the differing operations of each entity as well as other entities’ respective accounting policy choices.
