"In 2022, we returned nearly $8 billion of value to our shareholders through dividends and share repurchases, representing approximately 43% of our record adjusted funds from operations of $18 billion," said Kris Smith, Interim President and Chief Executive Officer. "We allocated nearly 60% of our excess funds to share buybacks and approximately 40% to debt reduction, and we're exiting the year with the highest dividend per share in our company's history, all of which reflect our unwavering commitment to maximizing shareholder returns."

Cash flow provided by operating activities, which includes changes in non-cash working capital, increased to $3.924 billion ($2.91 per common share) in the fourth quarter of 2022, compared to $2.615 billion ($1.80 per common share) in the prior year quarter.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Adjusted operating earnings<sup>(1)(2)</sup> increased to $2.432 billion ($1.81 per common share) in the fourth quarter of 2022, compared to $1.294 billion ($0.89 per common share) in the prior year quarter. Net earnings increased to $2.741 billion ($2.03 per common share) in the fourth quarter of 2022, compared to $1.553 billion ($1.07 per common share) in the prior year quarter.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Production from the company's Oil Sands assets was 688,100 barrels per day (bbls/d) in the fourth quarter of 2022, compared to 665,900 bbls/d in the prior year quarter, with the current period including record quarterly production at Firebag.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In 2022, Syncrude delivered record annual mine bitumen production, with both strong synthetic crude oil (SCO) production and by capitalizing on the company's regional integration through transfers on the interconnecting pipelines, all of which helped to achieve Suncor's second highest annual SCO production of 480,000 bbls/d.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Refining and Marketing (R&M) generated adjusted funds from operations<sup>(3)</sup> of $1.663 billion in the fourth quarter of 2022, or $2.102 billion excluding the impacts of a first-in, first-out (FIFO) inventory valuation loss<sup>(4)</sup> of $439 million, compared to $869 million of adjusted funds from operations in the prior year quarter, or $708 million excluding the impacts of a FIFO inventory valuation gain<sup>(4)</sup> of $161 million.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In 2022, Suncor returned over $7.7 billion of value to its shareholders, compared to $3.9 billion in the prior year. Record shareholder returns in 2022 included $2.6 billion of dividends paid and $5.1 billion in share repurchases. In 2022, the company repurchased a record 116.9 million common shares at an average price of $43.92 per common share, or the equivalent of 8.1% of its common shares as at December 31, 2021.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the fourth quarter of 2022, Suncor's Board of Directors (the Board) approved a quarterly dividend of $0.52 per share, a 23.8% increase over the fourth quarter of 2021 dividend and the highest quarterly dividend per share in the company's history.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Subsequent to the fourth quarter of 2022, the Board approved a renewal of the company's normal course issuer bid (NCIB) for the repurchase of up to 10% of Suncor's public float as at February 3, 2023, over a twelve-month period, and concurrently, the Toronto Stock Exchange (TSX) accepted a notice filed by Suncor to renew its NCIB in respect of the repurchase of such shares.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In support of its net debt reduction and annual capital allocation targets, the company reduced net debt<sup>(1)</sup> by nearly $1.0 billion in the fourth quarter of 2022, or $745 million excluding the impact of a $200 million unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt. In 2022, the company reduced net debt by over $2.5 billion, or approximately $3.2 billion excluding the impact of a $729 million unrealized foreign exchange loss on the revaluation of U.S. dollar denominated debt. The significant reduction in debt provides ongoing balance sheet flexibility, reduces long-term financing costs, and demonstrates the company's confidence in its business and commitment to reducing net debt.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the fourth quarter of 2022, as a result of a comprehensive strategic review of its downstream retail business, the company announced that it will retain and continue to improve and optimize the Petro-Canada™ retail business.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Subsequent to the fourth quarter of 2022, the company completed the sale of its wind and solar assets, and the acquisition of an additional working interest in Fort Hills, bringing the company's total aggregate working interest in Fort Hills to 68.76%. The sale process for the company's U.K. E&P portfolio is progressing, with a sale anticipated to close in mid-2023.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Beginning in the fourth quarter of 2021, the company revised the label of operating earnings (loss) and funds from (used in) operations to adjusted operating earnings (loss) and adjusted funds from (used in) operations, respectively, to better distinguish these non-GAAP financial measures from their respective comparable GAAP measures and better reflect the purpose of such measures. The composition of these measures remained unchanged and therefore no prior periods were revised.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Beginning in the first quarter of 2022, to align with how management evaluates segment performance, the company revised its segment presentation to reflect segment results before income tax expense and present tax at a consolidated level. This presentation change has no effect on consolidated net earnings (loss), adjusted operating earnings (loss) and adjusted funds from (used in) operations. Comparative periods have been revised to reflect this change. See the Income Tax section of this document for a discussion on income taxes.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The estimated impact of the last-in, first-out (LIFO) method is a non-GAAP financial measure. FIFO inventory valuation includes the impact of commodity risk management activities. See the Non-GAAP and Other Financial Measures Advisory section of this document.

#### Financial Results

#### Adjusted Operating Earnings
Suncor's adjusted operating earnings increased to $2.432 billion ($1.81 per common share) in the fourth quarter of 2022, compared to $1.294 billion ($0.89 per common share) in the prior year quarter, primarily due to significantly higher crude oil and refined product realizations, reflecting the improved business environment in the current quarter and higher upstream production, partially offset by increased operating expenses and income taxes. Adjusted operating earnings were also impacted by a weakening in benchmark pricing during the current quarter, compared to a strengthening in benchmark pricing in the prior year quarter, resulting in a FIFO inventory valuation loss in the fourth quarter of 2022, compared to a gain in the prior year quarter.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The bridge 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, and changes in the intersegment elimination of profit reported in the Corporate and Eliminations segment.

#### Net Earnings
The company had net earnings of $2.741 billion ($2.03 per common share) in the fourth quarter of 2022, compared to $1.553 billion ($1.07 per common share) in the prior year quarter. In addition to the factors impacting adjusted operating earnings discussed above, net earnings for the fourth quarter of 2022 included a $200 million unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt recorded in financing expenses, a $106 million unrealized loss on risk management activities recorded in other income (loss) and a $215 million income tax recovery excluded from adjusted operating earnings. Net earnings in the prior year quarter included a $227 million gain on the sale of the company's interest in the Golden Eagle Area Development, a $25 million unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt recorded in financing expenses, a $14 million unrealized gain on risk management activities recorded in other income (loss) and a $7 million income tax expense excluded from adjusted operating earnings.

All reconciling items are presented on a before-tax basis and adjusted for income taxes in the income tax (recovery) expense excluded from adjusted operating earnings line. See the Non-GAAP and Other Financial Measures Advisory section of this document.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the second quarter of 2022, as a result of the decision to restart the West White Rose Project, the company recorded a non-cash impairment reversal of $715 million on its share of the White Rose assets in the E&P segment. Also during the second quarter of 2022, as a result of the company's expected sale of its E&P assets in Norway, and the subsequently reached agreement for such sale, the company recorded a non-cash impairment of $70 million against its share of its assets in Norway in the E&P segment. During the third quarter of 2022, in connection with the company entering into a conditional agreement to acquire Teck Resources Limited's (Teck) interest in Fort Hills, as well as updates to the Fort Hills long-range plan including production and operating cost plans, the company recorded a non-cash impairment of $3.397 billion against its share of the Fort Hills assets in the Oil Sands segment. During the third quarter of 2021, the company recorded a non-cash impairment reversal of $221 million against its share of the Terra Nova assets, in the E&P segment, as a result of the Asset Life Extension Project moving forward and the benefit of royalty and financial support from the Government of Newfoundland and Labrador.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2022, the company recorded $147 million of property damage insurance proceeds in other income (loss) related to the company's assets in Libya in the E&P segment.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2022, the company incurred a $65 million foreign exchange loss related to the sale of the company's share of its assets in Norway in the E&P segment.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the first quarter of 2021, the company recorded a restructuring charge in operating, selling & general (OS&G) expenses related to workforce-reduction plans.

(6) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2021, the company recorded a loss of $80 million for the early repayment of long-term debt.

(7) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the fourth quarter of 2022, income tax (recovery) expense excluded from adjusted operating earnings includes a deferred income tax recovery of $171 million related to the anticipated sale of the company's U.K. E&P portfolio and a current income tax recovery of $39 million related to the sale of its wind and solar assets.

#### Adjusted Funds from Operations and Cash Flow Provided by Operating Activities
Adjusted funds from operations increased to $4.189 billion ($3.11 per common share) in the fourth quarter of 2022, compared to $3.144 billion ($2.17 per common share) in the prior year quarter. Adjusted funds from operations were influenced by the same factors impacting adjusted operating earnings noted above.

Cash flow provided by operating activities, which includes changes in non-cash working capital, increased to $3.924 billion ($2.91 per common share) in the fourth quarter of 2022, compared to $2.615 billion ($1.80 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 use of cash associated with the company's working capital balances in the fourth quarter of 2022 compared to the prior year quarter.

#### Operating Results
Suncor's total upstream production increased to 763,100 barrels of oil equivalent per day (boe/d) in the fourth quarter of 2022, compared to 743,300 boe/d in the prior year quarter, primarily driven by increased production from the company's Oil Sands assets.

The company's net SCO production was 517,500 bbls/d in the fourth quarter of 2022, comparable to 515,000 bbls/d in the prior year quarter. Increased SCO production at Syncrude, reflecting 99% upgrader utilization in the fourth quarter of 2022, compared to 90% in the prior year quarter, was partially offset by decreased production at Oil Sands Base as the current quarter was impacted by the completion of planned maintenance activities that commenced in the third quarter of 2022.

The company's non-upgraded bitumen production increased to 170,600 bbls/d in the fourth quarter of 2022, compared to 150,900 bbls/d in the fourth quarter of 2021, primarily due to increased production from Fort Hills and record quarterly production from Firebag.

Non-upgraded bitumen production from the company's In Situ assets in the fourth quarter of 2022 was higher than the prior year quarter, with an overall increase in bitumen production volumes being partially offset by increased Firebag production being diverted to upgrading in the current period, as the prior year quarter was impacted by maintenance activities at Firebag. During the fourth quarter of 2022, the company also leveraged its asset flexibility and marketing and trading expertise, including its midstream and logistics network, to mitigate third-party pipeline disruptions, resulting in additional non-upgraded bitumen production being sold to market.

E&P production during the fourth quarter of 2022 was 75,000 boe/d, compared to 77,400 boe/d in the prior year quarter. The decrease in production was primarily due to asset sales at E&P International, partially offset by increased production at E&P Canada.

Upstream production in 2023 is expected to be impacted by the disciplined decisions the company has taken to streamline its portfolio to enable greater fit and focus and drive value from its core business. This includes increased production associated with the company's additional working interest in Fort Hills, partially offset by reduced production reflecting the execution of its 36-month mine improvement plan, continued strong production from the company's In Situ assets, and the Terra Nova return to production in the second quarter of 2023, partially offset by the anticipated sale of the company's U.K. E&P business in 2023.

"We achieved combined upgrader utilization of 96% this quarter, delivered record Firebag production, and leveraged our asset and production flexibility as well as our midstream expertise to maximize the value of our barrels. In the downstream, we delivered refinery utilizations of 94%, supporting our ability to maximize margin capture in a robust demand environment," said Smith. "We have worked hard to mitigate the impacts of the weather-related outage at the Commerce City refinery and, as a result, we anticipate a return to normal production rates by the end of the first quarter. Looking ahead in 2023, we will continue to focus on the delivery of safe and reliable operations across the business."

Refinery crude throughput was 440,000 bbls/d and refinery utilization was 94% in the fourth quarter of 2022, compared to 447,000 bbls/d and 96% in the prior year quarter, with the decrease due to unplanned maintenance in the current period, including the weather-related event that occurred late in the quarter at the company's Commerce City refinery. Refined product sales in the fourth quarter of 2022 were 548,200 bbls/d, comparable to 550,100 bbls/d in the prior year quarter.

Progressive restart activities at the company's Commerce City refinery are currently underway, and the asset is anticipated to return to normal production rates by the end of the first quarter.

The company's total OS&G expenses were $3.556 billion in the fourth quarter of 2022, compared to $2.978 billion in the prior year quarter. The increase was mainly due to a significant increase in commodity input costs, including higher natural gas prices, increased maintenance, inflationary impacts and increased share-based compensation expense in the fourth quarter of 2022 compared to the prior year quarter. The company's exposure to higher natural gas costs is partially mitigated by revenue from power sales that is recorded in operating revenues.

#### Strategy Update
"Our top priority going into 2023 is driving the improved safety and operational performance of our company through our operational excellence principles, which in turn will deliver increased returns to shareholders," said Smith. "Our goal is to leverage our competitive advantages, including the scale and size of our integrated model, our regional oil sands advantage, and the improved fit and focus of our asset base, to drive cost and capital efficiency and maximize value from every barrel."

Suncor is laser focused on driving improved safety and operational performance across the company, and ensuring that it delivers competitive and sustainable value to its shareholders. Looking ahead, the company is executing on its clear and accelerated plans to improve its safety performance. This includes a full-scale implementation of collision awareness and fatigue management technologies, with installations occurring on over one thousand pieces of mobile mining equipment. Suncor will be the first oil sands operator to execute a full-scale implementation of these technologies, and the company is on track to go live

by the end of 2023. The company's rigorous safety improvement plans also include strengthening its risk management systems, improving its contractor safety management and doubling the safety weighting in its annual incentive program to drive safety across the business.

In the fourth quarter of 2022, Suncor's Board, with the support of external advisors, completed a comprehensive strategic review of its downstream retail business. As a result of the review, the company announced that it will retain and optimize the Petro-Canada™ retail business, with the goal of further strengthening Suncor's integrated R&M business and driving increased long-term value for shareholders. The enhancement of Suncor's retail business will include changing the mix ownership model of the company-owned and controlled, dealer-owned and partnership sites. Economic investment in 2023 is expected to be focused on company-owned and controlled sites, in the most profitable sites and markets, while optimizing the non-company-controlled sites in less densely populated areas, using alternative ownership structures and partnerships to grow the brand's scale and presence. These activities will also include the continued expansion of strategic partnerships in non-fuel-related businesses such as quick service restaurants, convenience stores, loyalty partnerships and energy transition offerings to provide low-carbon solutions to its customers.

In its Oil Sands business, the company is focused on leveraging its regional scale and standardized processes to drive cost efficiencies and reliability improvements, in addition to leveraging its interconnected asset base, including the interconnecting pipelines between Oil Sands Base and Syncrude, to improve the scope, duration and sequencing of turnarounds. In 2022, the company completed and commissioned the new paraffinic froth treatment (PFT) hot bitumen transfer piping which enables transfers of up to 60,000 bbls/d of PFT from Fort Hills to upgrading at Oil Sands Base, further increasing the company's regional integration and flexibility. The company continues to progress opportunities to further increase the integration and flexibility of its operations, which allows the company to manage through both internal and external market factors, and to respond to dynamic market conditions.

At Fort Hills, in the fourth quarter of 2022, the company commenced its 36-month mine improvement plan, which includes an accelerated sequence of mine development relative to historical plans, during which time the asset is expected to operate at lower than 90% production rates. During the fourth quarter of 2022, the company entered into an agreement to acquire Teck's 21.3% interest in the Fort Hills Project (Fort Hills) and its associated sales and logistics agreements for $1.0 billion, subject to working capital and other closing adjustments. Subsequent to the fourth quarter of 2022, TotalEnergies EP Canada Ltd. provided notice of the exercise of its contractual right of first refusal to acquire from Teck a 6.65% interest in Fort Hills, which reduced the amount of working interest available for Suncor to purchase. As a result, on February 2, 2023, Suncor completed the acquisition of an additional 14.65% working interest in Fort Hills for $688 million, before working capital and other closing adjustments, bringing the company's and its affiliate's total aggregate working interest in Fort Hills to 68.76%. The acquisition of the additional interest in Fort Hills is a strategic fit with the company's focus on its core assets, and underscores the company's confidence in the long-term value of the asset. At Syncrude, operating costs in 2023 are expected to increase as a result of structural mine progression factors that include longer hauling distances and increased tonnage and tailing requirements. Suncor's primary focus for cost management in 2023 will be to continue efforts to sustainably reduce controllable operating costs to offset inflationary pressures as much as possible, as well as the structural mine factors at Syncrude and Fort Hills, that are anticipated to increase near-term operating costs in its mining business.

By the end of 2022, the company achieved approximately $865 million of incremental free funds flow<sup>(1)</sup> through the implementation of digital, process and technology initiatives. The operating costs portion of the savings generated from these improvement initiatives is partially offsetting inflationary pressures and increased mining costs in the company's Oil Sands business. In addition, the company achieved $300 million of annual gross synergies for the Syncrude joint venture owners by the end of 2022, through workforce efficiencies and regional optimization.

The company continues to progress its disciplined decisions to streamline its portfolio to enable greater fit and focus and drive value from its core business. The sale process for the company's U.K. E&P portfolio is progressing, with a sale anticipated to close in mid-2023. In E&P Canada, investment in the Terra Nova Floating, Production, Storage and Offloading facility related to the Asset Life Extension Project was substantially progressed in 2022, and the asset has returned to Canada, with a safe return to production expected in the second quarter of 2023.

Subsequent to the fourth quarter of 2022, the company completed the sale of its wind and solar assets for gross proceeds of approximately $730 million, before closing adjustments and other closing costs, resulting in an estimated after-tax gain on sale of approximately $260 million. The sale of these assets allows greater focus and investment in hydrogen and renewable fuels, and accelerates the company's progress towards its net-zero greenhouse gas (GHG) objective with investments that are complementary to its base business and that leverage its existing expertise.

Reducing GHG emissions is a key component of the company's business strategy and long-term vision. In support of Suncor's ambition to be net-zero by 2050, the company works collaboratively with industry peers through the Pathways Alliance and also with Federal and Provincial governments. Subsequent to the fourth quarter of 2022, the Pathways Alliance was awarded exploratory rights from the Government of Alberta for the proposed carbon capture and storage hub to safely and permanently store CO2 captured from over 20 oil sands facilities in northern Alberta.

Looking forward, capital expenditures continue to be focused on asset sustainment and maintenance projects designed to support safe and reliable operations. Economic capital spend will be focused on advancing high-return projects and investments that are expected to enhance value within the company's existing assets base and accelerate the company's progress towards its net-zero GHG objective. Planned economic investment in 2023 is expected to include expenditures related to the replacement of the coke-fired boilers at Oil Sands Base with a cogeneration facility, which is expected to be in service in late 2024 and substantially contribute to the company's net-zero GHG objective, the Upgrader 1 coke drum replacement at Oil Sands Base, which is expected to be in service in late 2025, the Mildred Lake West Extension project, which is expected to come online in late 2025, investment in the West White Rose Project, with production expected to commence in the first half of 2026, and economic investment in the optimization of the Petro-Canada™ retail business.

In 2022, the company executed on its capital allocation framework, returning record value to shareholders of over $7.7 billion, while simultaneously reducing net debt by over $2.5 billion, or approximately $3.2 billion excluding the impact of a $729 million unrealized foreign exchange loss on the revaluation of U.S. dollar denominated debt. Record shareholder returns in 2022 included approximately $2.6 billion of dividends paid and approximately $5.1 billion in share repurchases, representing a record rate of share repurchases for the year. Demonstrating management's confidence in the company's ability to generate sustainable and increasing cash flows, and its commitment to increasing shareholder returns, the company increased its dividend per share twice in 2022, most recently in the fourth quarter, to $0.52 per share, a 23.8% increase over the fourth quarter of 2021 dividend and the highest quarterly dividend per share in the company's history.

Looking ahead in 2023, the company will continue to execute on its capital allocation framework. Based on current business plans and commodity pricing, the company expects to increase its share buyback allocation to 75% by the end of the first quarter of 2023, and to continue to progress towards its net debt reduction targets in 2023. The sustainability of, and ability to grow, the company's dividend is a top focus for Suncor and future dividend growth will continue to be a priority as momentum is demonstrated through reliable operational performance and optimization of the business. As well, as the company executes share buybacks, the lower outstanding share count will allow the company to increase its per-share dividend.

Subsequent to the fourth quarter of 2022, the Board approved a renewal of the company's NCIB for the repurchase of up to 10% of Suncor's public float as at February 3, 2023, over a twelve-month period, and concurrently, the TSX accepted a notice filed by Suncor to renew its NCIB in respect of the repurchase of such shares.

#### Corporate Guidance
Suncor has updated its 2023 Fort Hills production range from 90,000 bbls/d–100,000 bbls/d to 85,000 bbls/d–95,000 bbls/d, to reflect the lower incremental working interest purchased from Teck of 14.65%, with no change to Suncor's total upstream production range.

For further details and advisories regarding Suncor's 2023 corporate guidance, see www.suncor.com/guidance.

#### Normal Course Issuer Bid
Subsequent to the fourth quarter of 2022, the TSX accepted a notice filed by Suncor to renew its NCIB to purchase the company's common shares through the facilities of the TSX, New York Stock Exchange and/or alternative trading systems. The notice provides that, beginning February 17, 2023, and ending February 16, 2024, Suncor may purchase for cancellation up to 132,900,000 common shares, which is equal to approximately 10% of Suncor's public float as of February 3, 2023. On February 3, 2023, Suncor had 1,330,006,760 common shares issued and outstanding.

The actual number of common shares that may be purchased under the NCIB and the timing of any such purchases will be determined by Suncor. Suncor believes that, depending on the trading price of its common shares and other relevant factors, purchasing 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.

Pursuant to Suncor's previous NCIB, as amended on May 9, 2022, Suncor agreed that it would not purchase more than 143,500,000 common shares between February 8, 2022, and February 7, 2023. Between February 8, 2022, and February 7, 2023, and pursuant to Suncor's previous NCIB (as amended), Suncor repurchased 118,143,500 shares on the open market for approximately $5.248 billion, at a weighted average price of $44.42 per share.

Subject to the block purchase exemption that is available to Suncor for regular open market purchases under the NCIB, Suncor will limit daily purchases of Suncor common shares on the TSX in connection with the NCIB to no more than 25% (2,696,377 common shares) of the average daily trading volume of Suncor's common shares on the TSX during the previous six-month period (10,785,510 common shares). Purchases under the NCIB will be made through open market purchases at market price, as well as by other means as may be permitted by securities regulatory authorities. Suncor expects to enter into an automatic share purchase plan in relation to purchases made in connection with the NCIB on February 17, 2023.

1. ADVISORIES

#### Basis of Presentation
Unless otherwise noted, all financial information has been prepared in accordance with Canadian generally accepted accounting principles (GAAP), specifically International Accounting Standard (IAS) 34 *Interim Financial Reporting* as issued by the International Accounting Standards Board (IASB), which is within the framework of International Financial Reporting Standards (IFRS) as issued by the IASB.

All financial information is reported in Canadian dollars, unless otherwise noted. 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.

References to Oil Sands operations exclude Suncor's interests in Fort Hills and Syncrude.

Beginning in the first quarter of 2022, to align with how management evaluates segment performance, the company revised its segment presentation to reflect segment results before income tax expense and present tax at a consolidated level. This presentation change has no effect on consolidated net earnings (loss), adjusted operating earnings (loss) and adjusted funds from (used in) operations. Comparative periods have been revised to reflect this change. See the Income Tax section of this document for a discussion on income taxes.

#### Non-GAAP and Other Financial Measures
Certain financial measures in this document – namely adjusted operating earnings (loss), adjusted funds from (used in) operations, measures contained in return on capital employed (ROCE) and ROCE excluding impairments and impairment reversals, price realizations, Oil Sands operations cash operating costs, Fort Hills cash operating costs, Syncrude cash operating costs, refining and marketing gross margin, refining operating expense, free funds flow, net debt, total debt, last-in, first-out (LIFO) inventory valuation methodology and related per share or per barrel amounts or metrics that contain such measures – are not prescribed by GAAP. Adjusted operating earnings (loss) is defined in the Non-GAAP and Other Financial Measures Advisory section of this document and reconciled to the most directly comparable GAAP measures in the Consolidated Financial Information and Segment Results and Analysis sections of this document. Oil Sands operations cash operating costs, Fort Hills cash operating costs, Syncrude cash operating costs and LIFO inventory valuation methodology are defined in the Non-GAAP and Other Financial Measures Advisory section of this document and reconciled to the most directly comparable GAAP measures in the Segment Results and Analysis section of this document. Adjusted funds from (used in) operations, ROCE, ROCE excluding impairments and impairment reversals, price realizations, free funds flow, net debt, total debt, refining and marketing gross margin, and refining operating expense are defined and reconciled, where applicable, to the most directly comparable GAAP measures in the Non-GAAP and Other Financial Measures Advisory section of this document.

Beginning in the fourth quarter of 2021, the company changed the label of operating earnings (loss) and funds from (used in) operations to adjusted operating earnings (loss) and adjusted funds from (used in) operations, respectively, to better distinguish these non-GAAP financial measures from their respective comparable GAAP measures and better reflect the purpose of such measures. The composition of these measures remained unchanged and therefore no prior periods were revised.

#### Risk Factors and Forward-Looking Information
The company's business, reserves, financial condition and results of operations may be affected by a number of factors, including, but not limited to, the factors described within the Forward-Looking Information section of this document. This document contains forward-looking information based on Suncor's current expectations, estimates, projections and assumptions. This information is subject to a number of risks and uncertainties, including those discussed in this document, Suncor's Management's Discussion and Analysis (MD&A) for the year ended December 31, 2021, dated February 23, 2022 (the 2021 annual MD&A), and Suncor's other disclosure documents filed with Canadian securities regulatory authorities and the SEC, many of which are beyond the company's control. Users of this information are cautioned that actual results may differ materially. Refer to the Forward-Looking Information section of this document for information on the material risk factors and assumptions underlying our forward-looking information contained in this document.

#### Measurement Conversions
Certain crude oil and natural gas liquids volumes have been converted to mcfe on the basis of one bbl to six mcf. Also, certain natural gas volumes have been converted to boe or mboe on the same basis. Any figure presented in mcfe, boe or mboe may be misleading, particularly if used in isolation. A conversion ratio of one bbl of crude oil or natural gas liquids to six mcf of natural gas is based on an energy-equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, conversion on a 6:1 basis may be misleading as an indication of value.

#### Common Abbreviations
For a list of abbreviations that may be used in this document, refer to the Common Abbreviations section of this document.

FOURTH QUARTER DISCUSSION

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

2. FOURTH QUARTER HIGHLIGHTS

• **Fourth quarter financial results** 

&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Suncor's adjusted operating earnings<sup>(1)(2)</sup> increased to $2.432 billion ($1.81 per common share) in the fourth quarter of 2022, compared to $1.294 billion ($0.89 per common share) in the prior year quarter, primarily due to significantly higher crude oil and refined product realizations, reflecting the improved business environment in the current quarter and higher upstream production, partially offset by increased operating expenses and income taxes. Adjusted operating earnings were also impacted by a weakening in benchmark pricing during the current quarter, compared to a strengthening in benchmark pricing in the prior year quarter, resulting in a first-in, first-out (FIFO) inventory valuation loss in the fourth quarter of 2022, compared to a gain in the prior year quarter.

&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 company had net earnings of $2.741 billion ($2.03 per common share) in the fourth quarter of 2022, compared to $1.553 billion ($1.07 per common share) in the prior year quarter. In addition to the factors impacting adjusted operating earnings discussed above, net earnings for the fourth quarter of 2022 included a $200 million unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt recorded in financing expenses, a $106 million unrealized loss on risk management activities recorded in other income (loss) and a $215 million income tax recovery excluded from adjusted operating earnings. Net earnings in the prior year quarter included a $227 million gain on the sale of the company's interest in the Golden Eagle Area Development, a $25 million unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt recorded in financing expenses, a $14 million unrealized gain on risk management activities recorded in other income (loss) and a $7 million income tax expense excluded from adjusted operating earnings.

&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Adjusted funds from operations<sup>(1)(2)</sup> increased to $4.189 billion ($3.11 per common share) in the fourth quarter of 2022, compared to $3.144 billion ($2.17 per common share) in the prior year quarter. Adjusted funds from operations were influenced by the same factors impacting adjusted operating earnings noted above. Cash flow provided by operating activities, which includes changes in non-cash working capital, increased to $3.924 billion ($2.91 per common share) in the fourth quarter of 2022, compared to $2.615 billion ($1.80 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 use of cash associated with the company's working capital balances in the fourth quarter of 2022 compared to the prior year quarter.

• **Record Firebag production.** Production from the company's Oil Sands assets was 688,100 bbls/d in the fourth quarter of 2022, compared to 665,900 bbls/d in the prior year quarter, with the current period including record quarterly production at Firebag.

• **Syncrude record annual performance.** In 2022, Syncrude delivered record annual mine bitumen production, with both strong SCO production and by capitalizing on the company's regional integration through transfers on the interconnecting pipelines, all of which helped to achieve Suncor's second highest annual SCO production of 480,000 bbls/d.

• **Strong Refining and Marketing (R&M) cash flows.** R&M generated adjusted funds from operations<sup>(3)</sup> of $1.663 billion in the fourth quarter of 2022, or $2.102 billion excluding the impacts of a FIFO inventory valuation loss<sup>(4)</sup> of $439 million, compared to $869 million of adjusted funds from operations in the prior year quarter, or $708 million excluding the impacts of a FIFO inventory valuation gain<sup>(4)</sup> of $161 million.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Beginning in the fourth quarter of 2021, the company revised the label of operating earnings (loss) and funds from (used in) operations to adjusted operating earnings (loss) and adjusted funds from (used in) operations, respectively, to better distinguish these non-GAAP financial measures from their respective comparable GAAP measures and better reflect the purpose of such measures.

FIFO inventory valuation includes the impact of commodity risk management activities. See the Non-GAAP and Other Financial Measures Advisory section of this document.

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

• **Record annual shareholder returns.** In 2022, Suncor returned over $7.7 billion of value to its shareholders, compared to $3.9 billion in the prior year. Record shareholder returns in 2022 included $2.6 billion of dividends paid and $5.1 billion in share repurchases. In 2022, the company repurchased a record 116.9 million common shares at an average price of $43.92 per common share, or the equivalent of 8.1% of its common shares as at December 31, 2021.

• **Dividend increase.** In the fourth quarter of 2022, Suncor's Board of Directors (the Board) approved a quarterly dividend of $0.52 per share, a 23.8% increase over the fourth quarter of 2021 dividend and the highest quarterly dividend per share in the company's history.

• **Renewal of share repurchase program.** Subsequent to the fourth quarter of 2022, the Board approved a renewal of the company's normal course issuer bid (NCIB) for the repurchase of up to 10% of Suncor's public float as at February 3, 2023, over a twelve-month period, and concurrently, the Toronto Stock Exchange (TSX) accepted a notice filed by Suncor to renew its NCIB in respect of the repurchase of such shares.

• **Significant debt reduction.** In support of its net debt reduction and annual capital allocation targets, the company reduced net debt<sup>(1)</sup> by nearly $1.0 billion in the fourth quarter of 2022, or $745 million excluding the impact of a $200 million unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt. In 2022, the company reduced net debt by over $2.5 billion, or approximately $3.2 billion excluding the impact of a $729 million unrealized foreign exchange loss on the revaluation of U.S. dollar denominated debt. The significant reduction in debt provides ongoing balance sheet flexibility, reduces long-term financing costs, and demonstrates the company's confidence in its business and commitment to reducing net debt.

• **Results of retail review.** In the fourth quarter of 2022, as a result of a comprehensive strategic review of its downstream retail business, the company announced that it will retain and continue to improve and optimize the Petro-Canada™ retail business.

• **Driving fit and focus of asset portfolio.** Subsequent to the fourth quarter of 2022, the company completed the sale of its wind and solar assets, and the acquisition of an additional working interest in Fort Hills, bringing the company's total aggregate working interest in Fort Hills to 68.76%. The sale process for the company's U.K. E&P portfolio is progressing, with a sale anticipated to close in mid-2023.

#### Net Earnings
Suncor's consolidated net earnings for the fourth quarter of 2022 were $2.741 billion, compared to $1.553 billion in the prior year quarter. Net earnings were primarily influenced by the same factors that impacted adjusted operating earnings described in this section.

Other items affecting net earnings over these periods included:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; An unrealized foreign exchange gain on the revaluation of U.S. dollar denominated debt of $200 million recorded in financing expenses in the Corporate and Eliminations segment in the fourth quarter of 2022, compared to a gain of $25 million in the fourth quarter of 2021.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; An unrealized loss on risk management activities of $106 million recorded in other income (loss) in the fourth quarter of 2022, compared to a gain of $14 million in the fourth quarter of 2021.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the fourth quarter of 2021, the company recorded a gain of $227 million on the sale of the company's interest in the Golden Eagle Area Development, which was completed early in the fourth quarter of 2021 and recorded in the E&P segment.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; An income tax recovery excluded from adjusted operating earnings of $215 million in the fourth quarter of 2022, compared to an expense of $7 million in the fourth quarter of 2021.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the second quarter of 2022, as a result of the decision to restart the West White Rose Project, the company recorded a non-cash impairment reversal of $715 million on its share of the White Rose assets in the E&P segment. Also during the second quarter of 2022, as a result of the company's expected sale of its E&P assets in Norway, and the subsequently reached agreement for such sale, the company recorded a non-cash impairment of $70 million against its share of its assets in Norway in the E&P segment. During the third quarter of 2022, in connection with the company entering into a conditional agreement to acquire Teck Resources Limited's (Teck) interest in Fort Hills, as well as updates to the Fort Hills long-range plan including production and operating cost plans, the company recorded a non-cash impairment of $3.397 billion against its share of the Fort Hills assets in the Oil Sands segment. During the third quarter of 2021, the company recorded a non-cash impairment reversal of $221 million against its share of the Terra Nova assets, in the E&P segment, as a result of the Asset Life Extension Project moving forward and the benefit of royalty and financial support from the Government of Newfoundland and Labrador.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2022, the company recorded $147 million of property damage insurance proceeds in other income (loss) related to the company's assets in Libya in the E&P segment.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2022, the company incurred a $65 million foreign exchange loss related to the sale of the company's share of its assets in Norway in the E&P segment.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the first quarter of 2021, the company recorded a restructuring charge in operating, selling & general (OS&G) expenses related to workforce-reduction plans.

(6) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2021, the company recorded a loss of $80 million for the early repayment of long-term debt.

(7) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the fourth quarter of 2022, income tax (recovery) expense excluded from adjusted operating earnings includes a deferred income tax recovery of $171 million related to the anticipated sale of the company's U.K. E&P portfolio and a current income tax recovery of $39 million related to the sale of its wind and solar assets.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For an explanation of this bridge analysis, see the Non-GAAP and Other Financial Measures Advisory section of this document.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; All reconciling items are presented on a before-tax basis and adjusted for income taxes in the Income Tax bridge factor.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The bridge factor for Inventory Valuation is comprised of changes in the FIFO inventory valuation and realized commodity risk management activities reported in the R&M segment, and changes in the intersegment elimination of profit reported in the Corporate and Eliminations segment.

Suncor's adjusted operating earnings increased to $2.432 billion ($1.81 per common share) in the fourth quarter of 2022, compared to $1.294 billion ($0.89 per common share) in the prior year quarter, primarily due to significantly higher crude oil and refined product realizations, reflecting the improved business environment in the current quarter and higher upstream production, partially offset by increased operating expenses and income taxes. Adjusted operating earnings were also impacted by a weakening in benchmark pricing during the current quarter, compared to a strengthening in benchmark pricing in the prior year quarter, resulting in a FIFO inventory valuation loss in the fourth quarter of 2022, compared to a gain in the prior year quarter.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the fourth quarter of 2022, share-based compensation expense of $183 million included a $76 million expense recorded in the Oil Sands segment, a $5 million expense recorded in the E&P segment, a $28 million expense recorded in the R&M segment and a $74 million expense recorded in the Corporate and Eliminations segment. The fourth quarter of 2021 share-based compensation expense of $126 million included a $36 million expense recorded in the Oil Sands segment, a $4 million expense recorded in the E&P segment, a $21 million expense recorded in the R&M segment and a $65 million expense recorded in the Corporate and Eliminations segment. Other primarily includes non-recurring costs associated with investments in the company's digital transformation and its net-zero greenhouse gas (GHG) objective.

The company's total OS&G expenses were $3.556 billion in the fourth quarter of 2022, compared to $2.978 billion in the prior year quarter. The increase was mainly due to a significant increase in commodity input costs, including higher natural gas prices, increased maintenance, inflationary impacts and increased share-based compensation expense in the fourth quarter of 2022 compared to the prior year quarter. The company's exposure to higher natural gas costs is partially mitigated by revenue from power sales that is recorded in operating revenues.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 2-1-1 crack spreads are indicators of the refining margin generated by converting two barrels of WTI into one barrel of gasoline and one barrel of diesel. The crack spreads presented here generally approximate the regions into which the company sells refined products through retail and wholesale channels.

In the fourth quarter of 2022, crude oil and crack spread benchmarks improved compared to the prior year quarter and were impacted by increased demand in addition to supply uncertainty related to the current geopolitical conflict. Commodity market volatility increased during the fourth quarter of 2022, due to economic concerns regarding rising interest rates, inflationary pressures and future economic growth.

Suncor's sweet SCO price realizations are influenced primarily by the price of WTI at Cushing and by the supply and demand for sweet SCO from Western Canada. Sweet SCO price realizations in the fourth quarter of 2022 reflected an increase in WTI at Cushing, which averaged US$82.65/bbl compared to US$77.15/bbl in the prior year quarter, and also reflected favourable SYN-WTI differentials. Suncor also produces sour SCO, the price of which is influenced by various crude benchmarks, including, but not limited to, MSW at Edmonton and WCS at Hardisty. The price of sour SCO can also be affected by prices negotiated for spot sales. Prices for MSW at Edmonton increased to $110.05/bbl in the fourth quarter of 2022 compared to $93.25/bbl in the prior year quarter, and prices for WCS at Hardisty decreased to US$57.00/bbl in the fourth quarter of 2022, from US$62.50/bbl in the prior year quarter. The prices for WCS at Hardisty were also negatively impacted in the fourth quarter of 2022 as a result of pipeline disruptions extending down the U.S. Gulf Coast.

Bitumen production that Suncor does not upgrade is blended with diluent or SCO to facilitate delivery through pipeline systems. Net bitumen price realizations are, therefore, influenced by prices for Canadian heavy crude oil (WCS at Hardisty is a common reference), prices for diluent (Condensate at Edmonton) and SCO. Bitumen price realizations can also be affected by bitumen quality premiums and discounts, as well as spot sales, and the price differential between Hardisty, Alberta, and U.S. Gulf Coast benchmarks.

The company leverages the expertise of its marketing and logistics business to optimize midstream capacity to the U.S. Gulf Coast and this is reflected in bitumen and sour SCO price realizations. Bitumen prices were unfavourably impacted by the widening of heavy crude oil differentials in the fourth quarter of 2022.

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

Suncor's price realizations for production from E&P Canada and E&P International assets are influenced primarily by the price for Brent crude, which increased to US$88.65/bbl in the fourth quarter of 2022 compared to US$79.70/bbl in the prior year quarter.

Suncor's refining and marketing gross margins are primarily influenced by 2-1-1 benchmark crack spreads, which are industry indicators approximating the gross margin on a barrel of crude oil that is refined to produce gasoline and distillates. Market crack spreads are based on quoted near-month contracts for WTI and spot prices for gasoline and diesel and do not necessarily reflect the margins at a specific refinery. Suncor's realized refining and marketing gross margins are influenced by actual crude oil feedstock costs, refinery configuration, product mix and realized market prices unique to Suncor's refining and marketing business. In addition, U.S. regulatory renewable blending obligations influence the benchmark cracks, which may increase their volatility, while the cost of regulatory compliance is not deducted in calculating the benchmark cracks.

Suncor has developed an indicative 5-2-2-1 index based on publicly available pricing data to more accurately reflect Suncor's realized refining and marketing gross margin. This custom index is a single value representing a notional five barrels of crude oil of varying grades refined to produce two barrels each of gasoline and distillate and one barrel of secondary product to approximate Suncor's unique set of refinery configurations; overall crude slate and product mix; location, quality and grade differentials; and the benefits of its marketing margins. The custom index is calculated by taking the product value of refined products less the crude value of refinery feedstock excluding the impact of FIFO inventory accounting methodology. The product value incorporates the New York Harbor 2-1-1 crack, Chicago 2-1-1 crack, WTI benchmarks and a seasonal factor. The seasonal factor applies an incremental US$6.50/bbl in the first and fourth quarters and US$5.00/bbl in the second and third quarters and reflects the location, quality and grade differentials for refined products sold in the company's core markets during the winter and summer months, respectively. The crude value incorporates the SYN, WCS and WTI benchmarks.

Crack spreads are based on current crude feedstock prices, whereas actual earnings are accounted for on a FIFO basis in accordance with IFRS where a delay exists between the time that feedstock is purchased and when it is processed and when products are sold to a third party. A FIFO loss normally reflects a declining price environment for crude oil and finished products, whereas FIFO gains reflect an increasing price environment for crude oil and finished products. The company's realized refining and marketing gross margins are also presented on a LIFO basis, which is consistent with how industry benchmarks and the Suncor 5-2-2-1 index are calculated and with how management evaluates performance.

In the fourth quarter of 2022, the New York Harbor 2-1-1 and Chicago 2-1-1 benchmark crack spreads increased compared to the prior year quarter due to increased demand for transportation fuels and declining North American refined product inventory levels, and to compensate for increased costs associated with renewable blending regulatory obligations. The Suncor 5-2-2-1 index was US$51.90/bbl in the fourth quarter of 2022 compared to US$28.05/bbl in the fourth quarter of 2021, reflecting the significant increase in benchmark crack spreads.

The cost of natural gas used in Suncor's Oil Sands and Refining operations is primarily referenced to Alberta spot prices at AECO. The average AECO benchmark increased to $4.90/GJ in the fourth quarter of 2022, from $4.45/GJ in the prior year quarter.

Excess electricity produced at Suncor's Oil Sands assets is sold to the Alberta Electric System Operator, with the proceeds netted against the applicable cash operating cost per barrel metric. The Alberta power pool price significantly increased to an average of $213.95/MWh in the fourth quarter of 2022 compared to $107.30/MWh in the prior year quarter.

The majority of Suncor's revenues from the sale of oil and natural gas commodities are based on prices that are determined by or referenced to U.S. dollar benchmark prices, while the majority of Suncor's expenditures are realized in Canadian dollars. In the fourth quarter of 2022, the Canadian dollar weakened in relation to the U.S. dollar as the average exchange rate decreased to US$0.74 per one Canadian dollar from US$0.79 per one Canadian dollar in the prior year quarter. This rate decrease had a positive impact on price realizations for the company during the fourth quarter of 2022 when compared to the prior year quarter.

Suncor also has assets and liabilities, including approximately 75% of the company's debt, that are denominated in U.S. dollars and translated to Suncor's reporting currency (Canadian dollars) at each balance sheet date. A decrease in the value of the Canadian dollar, relative to the U.S. dollar, from the previous balance sheet date increases the amount of Canadian dollars required to settle U.S. dollar denominated obligations, while an increase in the value of the Canadian dollar, relative to the U.S. dollar, decreases the amount of Canadian dollars required to settle U.S. dollar denominated obligations. As at December 31, 2022, the Canadian dollar weakened in relation to the U.S. dollar as the exchange rate at the end of the period decreased to US$0.74 per one Canadian dollar from US$0.79 per one Canadian dollar in the prior year quarter. This rate decrease had a larger negative impact on the company's debt balances in the fourth quarter of 2022 when compared to the prior year quarter.

See the Income Tax section of this document for a discussion on income taxes.

The Oil Sands segment adjusted operating earnings increased to $1.719 billion in the fourth quarter of 2022, compared to $1.172 billion in the prior year quarter, primarily due to higher realized crude oil prices, lower DD&A, and higher sales. The increase in adjusted operating earnings was partially offset by increased operating expenses, related primarily to increased commodity input costs and maintenance.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Bitumen production from Oil Sands Base is upgraded, while bitumen production from In Situ operations is either upgraded or sold directly to customers, including Suncor's own refineries, with SCO and diesel yields of approximately 79% of bitumen feedstock input. Fort Hills bitumen is either sold directly to customers as finished bitumen, including Suncor's own refineries, or to Oil Sands Base for upgrading. Nearly all of the bitumen produced at Syncrude is upgraded to sweet SCO and a small amount of diesel, at an approximate yield of 85%.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Combined upgrader utilization rates are calculated using total upgraded production, inclusive of internally consumed diesel and internal transfers.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Both Oil Sands operations and Syncrude produce diesel, which is internally consumed in mining operations, and Fort Hills and Syncrude use internally produced diesel from Oil Sands Base within their mining operations. In the fourth quarter of 2022, Oil Sands operations production volumes included 10,700 bbls/d of internally consumed diesel, of which 7,000 bbls/d was consumed at Oil Sands Base, 2,200 bbls/d was consumed at Fort Hills and 1,500 bbls/d was consumed at Syncrude. Syncrude production volumes included 2,500 bbls/d of internally consumed diesel.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Internal feedstock transfers between Oil Sands operations and Syncrude through the interconnecting pipelines are included in gross SCO and bitumen production volumes. In the fourth quarter of 2022, Oil Sands operations production included 2,500 bbls/d of bitumen that was transferred to Suncor's share of Syncrude through the interconnecting pipelines. Syncrude production included 400 bbls/d of SCO and 4,500 bbls/d of bitumen that were transferred to Oil Sands Base through the interconnecting pipelines.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Internal feedstock transfers from Fort Hills to Oil Sands operations through the paraffinic froth treatment hot bitumen transfer piping are included in gross bitumen production volumes. In the fourth quarter of 2022, Fort Hills production included 900 bbls/d of bitumen that was transferred to Oil Sands Base.

The company's net SCO production was 517,500 bbls/d in the fourth quarter of 2022, comparable to 515,000 bbls/d in the prior year quarter. Increased SCO production at Syncrude, reflecting 99% upgrader utilization in the fourth quarter of 2022, compared to 90% in the prior year quarter, was partially offset by decreased production at Oil Sands Base as the current quarter was impacted by the completion of planned maintenance activities that commenced in the third quarter of 2022.

The company's non-upgraded bitumen production increased to 170,600 bbls/d in the fourth quarter of 2022, compared to 150,900 bbls/d in the fourth quarter of 2021, primarily due to increased production from Fort Hills and record quarterly production from Firebag.

Non-upgraded bitumen production from the company's In Situ assets in the fourth quarter of 2022 was higher than the prior year quarter, with an overall increase in bitumen production volumes being partially offset by increased Firebag production being diverted to upgrading in the current period, as the prior year quarter was impacted by maintenance activities at Firebag. During the fourth quarter of 2022, the company also leveraged its asset flexibility and marketing and trading expertise, including its midstream and logistics network, to mitigate third-party pipeline disruptions, resulting in additional non-upgraded bitumen production being sold to market.

Oil Sands price realizations increased in the fourth quarter of 2022 from the prior year quarter, in line with the higher commodity price environment.

#### Royalties
Royalties for the Oil Sands segment increased in the fourth quarter of 2022 compared to the prior year quarter, due to the increase in sales volumes, partially offset by the widening of heavy crude oil differentials.

#### Expenses and Other Factors
Total Oil Sands operating expenses increased in the fourth quarter of 2022 compared to the prior year quarter. See the reconciliation in the Cash Operating Costs section below for further details regarding cash operating costs and a breakdown of non-production costs by asset.

At Oil Sands operations, operating costs in the fourth quarter of 2022 increased compared to the prior year quarter, primarily due to increased maintenance costs.

At Fort Hills, operating costs in the fourth quarter of 2022 increased compared to the prior year quarter, primarily due to increased mining activity and higher production levels.

At Syncrude, operating costs in the fourth quarter of 2022 increased compared to the prior year quarter, primarily due to higher production levels and increased natural gas and other commodity prices.

In the fourth quarter of 2022, higher natural gas prices resulted in a $56 million increase in Oil Sands segment operating costs compared to the prior year quarter.

In the fourth quarter of 2022, DD&A expense was lower compared to the prior year quarter, as the prior year quarter included higher derecognition charges of property, plant and equipment.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Beginning in the second quarter of 2022, the company revised the presentation of its cash operating costs reconciliation to present Oil Sands inventory changes and internal transfers on an aggregate basis. Oil Sands inventory changes and internal transfers 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. Comparative periods have been updated to reflect this change, with no impact to total Oil Sands operations, Fort Hills or Syncrude cash operating costs or cash operating costs per barrel. In the fourth quarter of 2022 and twelve months ended December 31, 2022, Oil Sands OS&G includes ($49) million and ($263) million, respectively, of inventory changes and internal transfers. In the fourth quarter of 2021 and twelve months ended December 31, 2021, Oil Sands OS&G includes ($89) million and ($115) million, respectively, of inventory changes and internal transfers.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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. In addition, non-production costs include safe-mode costs associated with the deferral of capital projects and additional costs incurred in response to the COVID-19 pandemic. Non-production costs at Fort Hills and Syncrude also include, but are not limited to, excess power revenue from cogeneration units and an adjustment to reflect internally produced diesel from Oil Sands operations at the cost of production.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Oil Sands operations excess power capacity and other includes, but is not limited to, the operational revenue impacts of excess power from cogeneration units and 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<sup>(1)</sup> were $28.35 in the fourth quarter of 2022, compared to $28.10 in the prior year quarter, due to higher OS&G expenses, as detailed above, and decreased production. Excess power capacity and other costs at Oil Sands operations in the fourth quarter of 2022 were significantly higher than the prior year quarter, mainly due to an increase in excess power revenues resulting from significantly higher power prices, and an increase in non-monetary natural gas costs.

FOURTH QUARTER DISCUSSION

Fort Hills cash operating costs per barrel<sup>(1)</sup> decreased to $37.10 in the fourth quarter of 2022, compared to $45.55 in the prior year quarter, reflecting increased production, partially offset by higher OS&G expenses, as detailed above. Fort Hills non-production costs were higher in the current quarter compared to the prior year quarter mainly due to the increased price for internally sourced diesel, which is adjusted to reflect internally produced diesel from Oil Sands operations at the cost of production, and an increase in excess power revenues resulting from higher power prices.

Syncrude cash operating costs per barrel<sup>(1)</sup> were $34.60 in the fourth quarter of 2022, compared to $33.50 in the prior year quarter, reflecting higher OS&G expenses, as detailed above, partially offset by increased production. In the fourth quarter of 2022, non-production costs were higher compared to the prior year quarter primarily due to a larger share-based compensation expense in the current quarter, and the increased price for internally sourced diesel, which is adjusted to reflect internally produced diesel from Oil Sands operations at the cost of production.

#### Subsequent Event
During the fourth quarter of 2022, the company entered into an agreement to acquire Teck's 21.3% interest in the Fort Hills Project (Fort Hills) and its associated sales and logistics agreements for $1.0 billion, subject to working capital and other closing adjustments. Subsequent to the fourth quarter of 2022, TotalEnergies EP Canada Ltd. provided notice of the exercise of its contractual right of first refusal to acquire from Teck a 6.65% interest in Fort Hills, which reduced the amount of working interest available for Suncor to purchase. As a result, on February 2, 2023, Suncor completed the acquisition of an additional 14.65% working interest in Fort Hills for $688 million, before working capital and other closing adjustments, bringing the company's and its affiliate's total aggregate working interest in Fort Hills to 68.76%.

#### Planned Maintenance Update
There are no significant planned maintenance events scheduled for the first quarter of 2023.

See the Income Tax section of this document for a discussion on income taxes.

Adjusted operating earnings for the E&P segment in the fourth quarter of 2022 increased to $578 million compared to $376 million in the prior year quarter, with the increase primarily due to significantly higher realized crude prices and higher sales volumes in the fourth quarter of 2022, partially offset by increased operating and transportation expenses.

---

Production volumes for E&P Canada were 49,100 bbls/d in the fourth quarter of 2022, compared to 47,600 bbls/d in the prior year quarter, primarily due to increased production related to the company's additional working interest in White Rose and strong production at Hebron, partially offset by the impact of planned turnaround activities at Hibernia in the fourth quarter of 2022.

In E&P Canada, investment in the Terra Nova Floating, Production, Storage and Offloading facility related to the Asset Life Extension Project was substantially progressed in 2022, and the asset has returned to Canada, with a safe return to production expected in the second quarter of 2023.

E&P International production was 25,900 boe/d in the fourth quarter of 2022, compared to 29,800 boe/d in the prior year quarter, primarily due to the sale of the company's assets in Norway in the third quarter of 2022 and the Golden Eagle Area Development in the fourth quarter of 2021, and natural declines, partially offset by increased liftings at Libya in the fourth quarter of 2022 compared to the prior year quarter.

Total E&P sales volumes were 75,100 boe/d in the fourth quarter of 2022, compared to 67,200 boe/d in the prior year quarter, primarily due to a draw of inventory at E&P international in the current quarter, and a build of inventory at E&P Canada in both periods, associated with the timing of cargo sales at year-end.

Price realizations at E&P Canada and E&P International increased in the fourth quarter of 2022 from the prior year quarter, in line with the higher commodity price environment.

#### Royalties
E&P royalties in the fourth quarter of 2022 were comparable to the prior year quarter, with the increase in price realizations being offset by lower royalty rates associated with production mix.

#### Expenses and Other Factors
Operating and transportation expenses increased in the fourth quarter of 2022 compared to the prior year quarter, primarily due to a one-time transportation provision recorded in the fourth quarter of 2022 and increased costs at E&P Canada related to the Terra Nova Asset Life Extension Project and an increase in the company's working interest in White Rose.

DD&A and exploration expense in the fourth quarter of 2022 was comparable to the prior year quarter.

Financing expense and other increased in the fourth quarter of 2022 compared to the prior year quarter, primarily due to the impact of insurance settlements.

#### Planned Maintenance Update for Operated Assets
There are no significant planned maintenance events scheduled for the first quarter of 2023.

This presentation change has no effect on consolidated adjusted operating earnings (loss). Comparative periods have been revised to reflect this change. See the Income Tax section of this document for a discussion on income taxes.

R&M adjusted operating earnings in the fourth quarter of 2022 increased to $1.529 billion compared to $582 million in the prior year quarter. The increase in adjusted operating earnings was primarily due to a significant increase in refining and marketing margins as a result of significantly higher benchmark crack spreads in the current period, which was partially offset by a FIFO inventory valuation loss in the current period, compared to a gain in the prior year quarter, and increased operating and transportation expenses, primarily due to increased commodity input costs. In the fourth quarter of 2022, adjusted operating earnings included a before-tax FIFO inventory valuation loss, including the impact of commodity risk management activities, of $439 million on the decrease in crude and refined product benchmarks, compared to a $161 million gain in the prior year quarter.

Refinery crude throughput was 440,000 bbls/d and refinery utilization was 94% in the fourth quarter of 2022, compared to 447,000 bbls/d and 96% in the prior year quarter, with the decrease due to unplanned maintenance in the current period, including the weather-related event that occurred late in the quarter at the company's Commerce City refinery. Refined product sales in the fourth quarter of 2022 were 548,200 bbls/d, comparable to 550,100 bbls/d in the prior year quarter.

Progressive restart activities at the company's Commerce City refinery are currently underway, and the asset is anticipated to return to normal production rates by the end of the first quarter.

**Refining and Marketing Gross Margins**<sup>(1)</sup>

Refining and marketing gross margins were influenced by the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; On a LIFO<sup>(2)</sup> basis, Suncor's refining and marketing gross margin increased to $69.40/bbl in the fourth quarter of 2022, representing a new quarterly record, from $30.00/bbl in the prior year quarter. The increase was due to significantly higher distillate benchmark crack spreads reflecting a tight supply-demand balance, which was further supported by strong location and quality differentials from regional benchmarks to the company's local markets. On a LIFO basis, Suncor's refining and marketing gross margin represents 99% margin capture compared to Suncor's 5-2-2-1 index in the fourth quarter of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; On a FIFO basis, Suncor's refining and marketing gross margin increased to $59.30/bbl in the fourth quarter of 2022, from $33.60/bbl in the prior year quarter, due to the same factors noted above, in addition to FIFO inventory valuation impacts. In the fourth quarter of 2022, the FIFO method of inventory valuation, relative to an estimated LIFO<sup>(2)</sup> accounting method, including the impact of commodity risk management activities, resulted in a loss of $439 million before-tax. In the prior year quarter, FIFO, including the impact of commodity risk management activities, resulted in a gain of $161 million before-tax, for an unfavourable quarter-over-quarter impact of $600 million.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the first quarter of 2021, the company recorded a restructuring charge in OS&G expenses related to workforce-reduction plans.

(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; During the third quarter of 2021, the company recorded a loss of $80 million for the early repayment of long-term debt.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Non-GAAP financial measures. See the Non-GAAP and Other Financial Measures Advisory section of this document.

Corporate incurred an adjusted operating loss of $482 million in the fourth quarter of 2022, compared to $376 million in the prior year quarter. The increased loss was attributable to an operational foreign exchange loss in the current quarter, compared to a gain in the prior year quarter, increased costs associated with the early redemption of long-term debt in the fourth quarter of 2022, and increased OS&G expenses, which were partially offset by a net decrease in interest expense on debt in the current quarter as a result of debt reductions that occurred throughout 2022, and an increase in interest revenue on the company's cash and short-term investment balances. Increased OS&G expenses in the fourth quarter of 2022 compared to the prior year quarter were primarily due to increased investment related to the company's progress towards its net-zero GHG emissions objective and digital transformation. Suncor capitalized $44 million of its borrowing costs in the fourth quarter of 2022, as part of the cost of major development assets and construction projects in progress, compared to $38 million in 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 produced from internal purchases of crude feedstock have been sold to third parties. During the fourth quarter of 2022, the company realized $100 million of intersegment profit, compared to a realization of $34 million of intersegment profit in the prior year quarter. The realization of intersegment profit and elimination of unrealized losses in the fourth quarter of 2022 was driven by a weakening in benchmark pricing in the current period.

Corporate and Eliminations adjusted funds used in operations were $273 million for the fourth quarter of 2022, compared to $252 million in the fourth quarter of 2021, and were influenced by the same factors impacting adjusted operating loss described above, excluding the impact of costs associated with the early redemption of long-term debt in the fourth quarter of 2022.

The provision for income taxes in the fourth quarter of 2022 increased compared to the prior year quarter, primarily due to increased earnings. In the fourth quarter of 2022, the company's effective tax rate on net earnings decreased compared to the prior year quarter, primarily due to the impact of deferred and current income tax recoveries related to the expected sale of the company's U.K. E&P portfolio and the sale of its wind and solar assets, non-taxable foreign exchange gains and losses on the revaluation of U.S. dollar denominated debt and other permanent items impacting total tax expense, which was partially offset by income earned in foreign jurisdictions with higher statutory tax rates.

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

During the fourth quarter of 2022, the company spent $1.258 billion on capital expenditures, excluding capitalized interest, compared to $1.146 billion in the prior year quarter. The increase in capital expenditures in the current quarter was primarily due to increased asset sustainment and maintenance capital expenditures at Oil Sands Base, increased asset sustainment and maintenance capital expenditures at R&M, and increased economic investment capital expenditures in E&P, primarily due to development work at the West White Rose Project in the current period, which was partially offset by decreased economic investment capital expenditures at In Situ and in Corporate.

Activity in the fourth quarter of 2022 is summarized by business unit below.

#### Oil Sands
Oil Sands Base capital expenditures were $527 million in the fourth quarter of 2022 and were primarily focused on asset sustainment and maintenance activities, as well as economic investment to progress low-carbon power cogeneration to replace the coke-fired boilers.

Syncrude capital expenditures were $201 million in the fourth quarter of 2022, the majority of which were for asset sustainment and maintenance expenditures relating to the company's planned maintenance program. Economic investment during the quarter was directed towards progressing the Mildred Lake West Extension mining project.

#### Exploration and Production
E&P capital and exploration expenditures were $109 million in the fourth quarter of 2022 and were related to economic investment projects, primarily related to the Terra Nova Asset Life Extension Project and development work at the West White Rose Project.

ROCE would have been 8.2% for the twelve months ended December 31, 2021, excluding the impact of the impairment reversal of $221 million ($168 million after-tax) in the third quarter of 2021.

#### 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 to fund its planned 2023 capital spending program of $5.4 billion to $5.8 billion and to meet current and future 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 a number of factors, including commodity prices, production and 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 will be with counterparties with investment grade debt ratings.

#### Available Sources of Liquidity
For the three months ended December 31, 2022, cash and cash equivalents decreased to $1.980 billion from $4.659 billion at September 30, 2022, due to the significant repayment of long-term debt, the company's capital and exploration expenditures, the repurchase of Suncor's common shares under its NCIB, and the payment of dividends exceeding cash flow provided by operating activities, including income tax instalments paid.

For the twelve months ended December 31, 2022, cash and cash equivalents decreased to $1.980 billion from $2.205 billion at December 31, 2021, due to the repurchase of Suncor's common shares under its NCIB, the significant repayment of long-term debt, the company's capital and exploration expenditures, and the payment of dividends in the twelve months ended December 31, 2022, exceeding cash flow provided by operating activities, including income tax instalments paid, and an increase in short-term indebtedness.

As at December 31, 2022, the weighted average days to maturity of the company's short-term investment portfolio was approximately 9 days.

Available credit facilities for liquidity purposes as at December 31, 2022, were $2.900 billion, compared to $4.247 billion at December 31, 2021. The decrease in liquidity was primarily due to an increase in short-term indebtedness.

#### Financing Activities
Management of debt levels and liquidity continues to be a priority for Suncor given the company's long-term plans and future expected volatility in the current business environment. Suncor believes a phased and flexible approach to existing and future projects should assist the company in maintaining 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 to not exceed 65% of its total debt plus shareholders' equity. At December 31, 2022, total debt to total debt plus shareholders' equity was 28.4% (December 31, 2021 – 33.4%). The company also continues to be in compliance with all operating covenants under its debt agreements.

The company's total debt decreased in the fourth quarter of 2022 primarily due to the significant repayment of long-term debt made during the fourth quarter of 2022, and favourable foreign exchange rates on U.S. dollar denominated debt compared to September 30, 2022, which was partially offset by leases entered into during the period.

The company's total debt decreased in the twelve months ended December 31, 2022, primarily due to the significant repayment of long-term debt and principal lease payments made during the twelve months ended December 31, 2022, which was partially offset by an increase in short-term indebtedness in the period, unfavourable foreign exchange rates on U.S. dollar denominated debt compared to December 31, 2021, and leases entered into during the period.

At December 31, 2022, Suncor's net debt was $13.639 billion, compared to $14.584 billion at September 30, 2022, and $16.149 billion at December 31, 2021. The change in net debt was primarily due to the factors listed above, which was partially offset by a decrease in cash and cash equivalents.

During the fourth quarter of 2022, in support of its debt reduction and annual capital allocation targets, the company repaid approximately $3.6 billion of its various notes below par.

FOURTH QUARTER DISCUSSION

#### Share Repurchases
In the first quarter of 2022, the TSX accepted a notice filed by Suncor to renew its NCIB to repurchase up to 5% of the company's outstanding common shares through the facilities of the TSX, NYSE and/or alternative trading systems. The notice provided that, beginning February 8, 2022, and ending February 7, 2023, Suncor may purchase for cancellation up to 71,650,000 common shares, which is equal to approximately 5% of Suncor's issued and outstanding common shares as at the date hereof. As at January 31, 2022, Suncor had 1,435,748,494 common shares issued and outstanding.

During the second quarter of 2022, and following the Board's approval to increase the company's share repurchase program to up to 10% of the company's public float, Suncor received approval from the TSX to amend its existing NCIB effective as of the close of markets on May 11, 2022, to increase the maximum number of common shares that may be repurchased in the period beginning February 8, 2022, and ending February 7, 2023, from 71,650,000 common shares, or approximately 5% of Suncor's issued and outstanding common shares as at January 31, 2022, to 143,500,000, or approximately 10% of Suncor's public float as at January 31, 2022. No other terms of the NCIB were amended. Suncor security holders may obtain a copy of the amended notice, without charge, by contacting the company.

Subsequent to the fourth quarter of 2022, the TSX accepted a notice filed by Suncor to renew its NCIB to purchase the company's common shares through the facilities of the TSX, New York Stock Exchange and/or alternative trading systems. The notice provides that, beginning February 17, 2023, and ending February 16, 2024, Suncor may purchase for cancellation up to 132,900,000 common shares, which is equal to approximately 10% of Suncor's public float as of February 3, 2023. On February 3, 2023, Suncor had 1,330,006,760 common shares issued and outstanding.

Between February 8, 2022, and February 7, 2023, and pursuant to Suncor's previous NCIB (as amended), Suncor repurchased 118,143,500 shares on the open market, representing the equivalent of 8.2% of its common shares as at January 31, 2022, for $5.248 billion, at a weighted average price of $44.42 per share.

The actual number of common shares that may be purchased under the NCIB and the timing of any such purchases will be determined by Suncor. Suncor believes that, depending on the trading price of its common shares and other relevant factors, purchasing 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.

#### Contractual Obligations, Commitments, Guarantees and Off-Balance Sheet Arrangements
In the normal course of business, the company is obligated to make future payments, including contractual obligations and non-cancellable commitments. Suncor has included these items in the Financial Condition and Liquidity section of the 2021 annual MD&A and has provided an update below. Suncor does not believe it has 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.

During the fourth quarter of 2022, the company decreased its commitments as a result of early debt repayments of approximately $3.6 billion of its various notes, which is expected to have a significant impact on the company's long-term debt and interest payments on long-term debt. This was partially offset by an increase in commitments associated with the company's decommissioning and restoration costs, as well as increases to its leases, primarily due to building lease extensions entered into during the quarter. Refer to note 6 to the unaudited interim Consolidated Financial Statements for the three and twelve months ended December 31, 2022, and to note 21 and note 24 to the audited Consolidated Financial Statements for the year ended December 31, 2021, for more details on the company's long-term debt and decommissioning and restoration balances.

8. QUARTERLY FINANCIAL DATA

Trends in Suncor's quarterly revenue, earnings and adjusted funds from operations are driven primarily by production volumes, which can be significantly impacted by major maintenance events, changes in commodity prices and crude differentials, refining crack spreads, foreign exchange rates and other significant events impacting operations, such as operational incidents and the impacts of the COVID-19 pandemic.

9. 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 2021 annual MD&A and in notes 3 and 5 of Suncor's audited Consolidated Financial Statements for the year ended December 31, 2021.

#### 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 which, 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, 2021, and in the Accounting Policies and Critical Accounting Estimates section of Suncor's 2021 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. The company also uses physical and financial energy derivatives to earn trading profits. 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, 2021, note 9 to the unaudited interim Consolidated Financial Statements for the three and twelve months ended December 31, 2022, and the Financial Condition and Liquidity section of the 2021 annual MD&A.

FOURTH QUARTER DISCUSSION

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

10. 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, Oil Sands operations cash operating costs, Fort Hills cash operating costs, Syncrude cash operating costs, refining and marketing gross margin, refining operating expense, 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.

Beginning in the fourth quarter of 2021, the company changed the label of operating earnings (loss) and funds from (used in) operations to adjusted operating earnings (loss) and adjusted funds from (used in) operations, respectively, to better distinguish these non-GAAP financial measures from their respective comparable GAAP measures and better reflect the purpose of such measures. The composition of these measures remained unchanged and therefore no prior periods were revised.

#### 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 Information and Segment Results and Analysis sections of this document.

Beginning in the first quarter of 2022, to align with how management evaluates segment performance, the company revised its segment presentation to reflect segment results before income tax expense and present tax at a consolidated level. This presentation change has no effect on consolidated adjusted operating earnings (loss). Comparative periods have been revised to reflect this change. See the Income Tax section of this document for a discussion on income taxes.

#### Bridge Analyses of Adjusted Operating Earnings (Loss)
Throughout this document, the company presents charts that illustrate 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 analyses in particular sections of this document. These bridge analyses are presented because management uses this presentation to evaluate performance.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The factor for Sales Volumes and Mix is calculated based on sales volumes and mix for the Oil Sands and E&P segments and throughput volumes for the R&M segment.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The factor for Price, Margin and Other Revenue includes upstream price realizations before royalties, with the exception of Libya, 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.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The factor for Royalties excludes the impact of Libya, as royalties in Libya are taken into account in Price, Margin and Other Revenue as described above.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The factor for Inventory Valuation includes the before-tax impact of the FIFO method of inventory valuation in the company's 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, as both represent inventory valuation adjustments, and downstream realized commodity risk management activities.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The factor for Operating and Transportation Expense includes project startup costs, operating, selling and general expense, and transportation expense.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The factor for DD&A and Exploration Expense includes depreciation, depletion and amortization expense, and exploration expense.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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.

#### Return on Capital Employed (ROCE) and ROCE Excluding Impairments and Impairment Reversals
ROCE is a measure 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.

FOURTH QUARTER DISCUSSION

**Adjusted Funds From (Used In) Operations**<sup>(1)</sup>

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 management's discussion and analysis 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.sedar.com.

#### Free Funds Flow
Free funds flow is a non-GAAP financial measure that is calculated by taking adjusted funds from operations and subtracting capital expenditures, including capitalized interest. Free funds flow reflects cash available for increasing distributions to shareholders and reducing debt. Management uses free funds flow to measure the capacity of the company to increase returns to shareholders and to grow Suncor's business.

#### Oil Sands Operations, Fort Hills and Syncrude Cash Operating Costs
Cash operating costs are calculated by adjusting Oil Sands segment OS&G expense for i) non-production costs that management believes do not relate to production performance, including, but not limited to, share-based compensation adjustments, research costs, safe-mode costs associated with the deferral of capital projects, additional costs incurred in response to the COVID-19 pandemic, adjustments to reflect the cost of internal transfers in the receiving asset at the cost of production and the expense recorded as part of a non-monetary arrangement involving a third-party processor; ii) revenues associated with excess capacity, including excess power generated and sold that is recorded in operating revenue; and iii) project startup costs. Oil Sands operations and Syncrude production volumes are gross of internally consumed diesel and feedstock transfers between assets through the interconnecting pipelines. 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.

#### Refining and Marketing Gross Margin and Refining Operating Expense
Refining and marketing gross margins 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 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. Management uses refining and marketing gross margin and refining operating expense to measure operating performance on a production barrel basis.

FOURTH QUARTER DISCUSSION

#### Impact of First-in, First-out (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 (which can be several weeks for foreign offshore crude purchases), 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 United States GAAP (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, current portion of long-term lease liabilities, long-term debt and long-term lease liabilities (all of which are GAAP measures). Net debt is equal to total debt less cash and cash equivalents (a GAAP measure).

• *Suncor's updated 2023 Fort Hills production range.* 

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.

Factors that affect our 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 in order 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 and currency exchange rates (including as a result of demand and supply effects resulting from the COVID-19 pandemic and the actions of OPEC+); 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; maintaining 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; risks and uncertainties associated with closing a transaction for the purchase or sale of a business, asset or oil and gas property, including estimates of the final consideration to be paid or received; 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 Aboriginal 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 2021 annual MD&A, the 2021 AIF and Form 40-F on file with Canadian securities commissions at www.sedar.com 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.

2. Basis of Preparation

(a) Statement of Compliance

These condensed interim consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, specifically International Accounting Standard 34 *Interim Financial Reporting* as issued by the International Accounting Standards Board. 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, 2021.

(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, 2021.

(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, 2021.

(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.

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 and natural gas 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. Beginning in the first quarter of 2022, to align with how management evaluates segment performance, the company revised its segment presentation to reflect segment results before income tax expense and present tax at a consolidated level. This presentation change has no effect on consolidated net earnings and comparative periods have been revised to reflect this change.

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

(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:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Level 3 consists of instruments with a fair value that is determined by prices with significant unobservable inputs. As at December 31, 2022, 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, 2022:

---

| | | | | |
|:---|:---|:---|:---|:---|
| ($ millions)  | Level 1 | Level 2 | Level 3 | Total Fair Value |
| Accounts receivable | 36 | 107 | &nbsp;&nbsp;&nbsp;&nbsp; – &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; | 143 |
| Accounts payable | (85) | (123) | &nbsp;&nbsp;&nbsp;&nbsp; – &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; | (208) |
|  | (49) | (16) | &nbsp;&nbsp;&nbsp;&nbsp; – &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; | (65) |

---

During the fourth quarter of 2022, there were no transfers between Level 1 and Level 2 fair value measurements.

#### Non-Derivative Financial Instruments
At December 31, 2022, the carrying value of fixed-term debt accounted for under amortized cost was $9.8 billion (December 31, 2021 – $14.2 billion) and the fair value was $9.4 billion (December 31, 2021 – $17.4 billion). The estimated fair value of long-term debt is based on pricing sourced from market data.

10. Asset Transactions and Valuations

#### Oil Sands Fort Hills assets:
During the fourth quarter of 2022, the company entered into an agreement to acquire Teck Resources Limited's (Teck) 21.3% interest in the Fort Hills Project (Fort Hills) and its associated sales and logistics agreements for $1.0 billion, subject to working capital and other closing adjustments. Subsequent to the fourth quarter of 2022, TotalEnergies EP Canada Ltd. provided notice of the exercise of its contractual right of first refusal to acquire from Teck a 6.65% interest in Fort Hills, which reduced the amount of working interest available for Suncor to purchase. As a result, on February 2, 2023, Suncor completed the acquisition of an additional 14.65% working interest in Fort Hills for $688 million, before working capital and other closing adjustments, bringing the company's and its affiliate's total aggregate working interest in Fort Hills to 68.76%. Due to the limited time between the acquisition and the preparation of these consolidated financial statements, the timing of closing adjustments, the value of the assets acquired and the liabilities assumed on the acquisition were not finalized to complete the purchase price allocation.

Prior to entering the agreement with Teck, the company also updated its long-range plan for Fort Hills, which incorporated lower gross production and increased operating costs per barrel for the next 36 months. Management considered these indicators of impairment and performed an asset impairment test using recoverable amounts based on fair value less costs of disposal. An impairment charge of $2.6 billion (net of taxes of $0.8 billion) was recognized on its share of Fort Hills in the Oil Sands segment

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

in the third quarter of 2022. An expected cash flow approach with the following asset specific assumptions (Level 3 fair value inputs note 9) were applied:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Western Canada Select (WCS) price forecast of US$69.00/bbl in 2023, US$62.00/bbl in 2024, and an average price of US$50.00/bbl between 2025 and 2031, escalating at 2% per year thereafter over the life of the project up to 2060, adjusted for asset-specific location and quality differentials;

• &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 company's share of production ranging from 87,000 to 106,000 bbls/d over the life of the project;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cash operating costs averaging approximately $25.00/bbl over the life of the project (expressed in real dollars), which reflects operating, selling and general expenses adjusted for non-production costs, including share-based compensation, research costs, and excess power revenue;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; foreign exchange rate of US$0.76 per one Canadian dollar; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; risk adjusted discount rate of 8.25% (after-tax).

The recoverable amount of the Fort Hills cash generating unit (CGU) was $2.8 billion (net of taxes) as at September 30, 2022. The recoverable amount estimate is most sensitive to price and discount rate. A 5% average decrease in price over the life of the project would have resulted in an additional impairment charge of approximately $1.0 billion (after-tax) on the company's share of the Fort Hills assets. A 1% increase in the discount rate would have resulted in an additional impairment charge of approximately $0.2 billion (after-tax) on the company's share of the Fort Hills assets.

No indicators of impairment or reversals of impairment were identified at December 31, 2022.

During the fourth quarter of 2021, the company performed an asset impairment test on its share of Fort Hills in the Oil Sands segment. The recoverable amount was $5.5 billion as at December 31, 2021, which indicated that no impairment loss or reversal was required.

#### Exploration and Production White Rose assets:
In the second quarter of 2022, the company announced that concurrent with the decision to restart the West White Rose project by the joint venture owners, Suncor increased its ownership in the White Rose asset by 12.5% to approximately 39% (previously approximately 26%). The decision to restart was driven by a revised royalty structure and development plan. The company received $38 million (net of taxes of $12 million) in cash consideration to acquire the additional working interest, which was primarily allocated to the asset retirement obligation and property, plant and equipment of the project. As a result of these events, during the second quarter of 2022, the company performed an impairment reversal test on the White Rose CGU as the recoverable amount of this CGU was sensitive to the restart decision. The impairment reversal test was performed using a recoverable amount based on the fair value less cost of disposal. An expected cash flow approach was used with the key assumptions discussed below (Level 3 fair value inputs – note 9).

As a result of the impairment reversal test, the recoverable amounts were determined to be greater than the carrying values of the White Rose CGU and the company recorded an impairment reversal of $542 million (net of taxes of $173 million) on its previous share of the White Rose assets in the Exploration and Production segment. The recoverable amount was determined based on the following asset-specific assumptions:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Brent price forecast of US$85.00/bbl in 2023, US$68.00 in 2024 and US$69.00 in 2025, escalating at 2% per year thereafter over the life of the project to 2038 and adjusted for asset-specific location and quality differentials;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; anticipated first oil for the West White Rose project in the first half of 2026 and the company's share of production of approximately 9,800 bbls/d (based on its previous working interest of approximately 26%) over the life of the project;

• &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 company's share of future capital expenditures of $1.5 billion, including the West White Rose expansion; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; risk-adjusted discount rate of 9.0% (after-tax).

No other indicators of impairment or reversals of impairment were identified at December 31, 2022.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

#### Norway assets:
During the third quarter of 2022, the company completed the sale of its Norway assets, including its 30% working interest in Oda and its 17.5% working interest in the Fenja Development Joint Operations, for net proceeds of $297 million (net of cash disposed of $133 million), resulting in a $65 million loss including foreign exchange impacts. The company completed the sale on September 30, 2022. The Norway assets are reported in the Exploration and Production segment.

In the second quarter of 2022, the company reclassified the assets and liabilities related to its Norway operations as assets held for sale and performed an impairment test on the Norway assets held for sale as at June 30, 2022. The impairment test was performed using the lower of its carrying amount and fair value less costs to sell (Level 2 fair value inputs – note 9). As a result of the impairment test, the company recorded a $47 million charge related to the impairment on its share of the Norway operations, net of a $23 million deferred tax adjustment associated with the assets held for sale.

11. Provisions

Suncor's decommissioning and restoration provision increased by $1.3 billion for the twelve months ended December 31, 2022 due to a $3.6 billion increase in the estimated discounted cash flows primarily related to water treatment costs for mining assets, offset by a decrease of $2.5 billion due to an increase in the credit-adjusted risk-free interest rate to 5.50% (December 31, 2021 – 3.70%)

12. Pensions and Other Post-Retirement Benefits

For the twelve months ended December 31, 2022, the actuarial gain on employee retirement benefit plans was $838 million (net of taxes of $264 million), mainly due to an increase in the discount rate to 5.10% (December 31, 2021 – 2.90%).

13. Assets held for Sale

In the third quarter of 2022, the company reclassified the assets and liabilities related to its United Kingdom (U.K.) operations, including its interests in Buzzard and Rosebank located in the U.K. sector of the North Sea, as assets held for sale. The sales process is progressing, with a sale anticipated to close in mid-2023. The U.K. operations are reported within the Exploration and Production segment.

(A) &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 company revised the presentation of certain gross revenues and purchases of crude oil and products to align with the current period presentation. For the three months ended March 31, 2022, gross revenues and purchases of crude oil and products were decreased by $150 million, with no effect on net earnings.

(B) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Beginning in the first quarter of 2022, to align with how management evaluates segment performance, the company revised its segment presentation to reflect segment results before income tax expense and present tax at a consolidated level. This presentation change has no effect on consolidated net earnings (loss), adjusted operating earnings (loss) and adjusted funds from (used in) operations. Comparative periods have been revised to reflect this change. See the Income Tax section of the MD&A for a discussion on income taxes.

(C) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Non-GAAP financial measures or contains non-GAAP financial measures. See the Operating Summary Information – Non-GAAP Financial Measures section of this Quarterly Report.

(D) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Beginning in the fourth quarter of 2021, the company revised the label of operating earnings (loss) and funds from (used in) operations to adjusted operating earnings (loss) and adjusted funds from (used in) operations respectively, to better distinguish these non-GAAP financial measures from their respective comparable GAAP measures and better reflect the purpose of such measures. The composition of these measures remained unchanged and therefore no prior periods were revised.

(E) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Represents on a basic per share basis.

(F) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Excludes capital expenditures related to assets held for sale of $16 million in the fourth quarter of 2022 and $57 million for twelve months ended December 31, 2022.

(G) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Excludes capital expenditures related to assets held for sale of $24 million in the fourth quarter of 2022 and $76 million for twelve months ended December 31, 2022.

(B) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In Q2 2021, the company began disclosing refinery rack forward margin and operating expenses to increase transparency into Suncor's integrated model and align with how management evaluates the performance of the business. Rack forward encompasses Suncor's retail and wholesale business. As an integrated oil and gas company, transfer prices are used to attribute margin to the value chain. The company's transfer prices affecting the refining, supply and rack forward businesses employ replacement cost methodology, which may differ from those subject to supply agreements negotiated by independent market participants. Rack forward margins may include any incremental location differentials above replacement supply cost, as well as the applicable retail and wholesale channel margins generated within those markets.

Rack forward encompasses Suncor's retail and wholesale business. As an integrated oil and gas company, transfer prices are used to attribute margin to the value chain. The company's transfer prices affecting the refining, supply and rack forward businesses employ replacement cost methodology, which may differ from those subject to supply agreements negotiated by independent market participants. Rack forward margins may include any incremental location differentials above replacement supply cost, as well as the applicable retail and wholesale channel margins generated within those markets.

Operating Summary Information

#### Non-GAAP Financial Measures
Certain financial measures in this document – namely adjusted operating earnings (loss), adjusted funds from (used in) operations, 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 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 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 Reports). Adjusted funds from (used in) operations is defined and reconciled to GAAP measures in the Non-GAAP Financial Measures Advisory section of each respective Quarterly Report. Refining and marketing gross margin, rack forward gross margin, refining operating expense and rack forward operating expense are defined in the Non-GAAP Financial Measures Advisory section and reconciled to GAAP measures in the Operating Metrics Reconciliation section of each respective Quarterly Report. 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.

Beginning in the fourth quarter of 2021, the company changed the label of operating earnings (loss) and funds from (used in) operations to adjusted operating earnings (loss) and adjusted funds from (used in) operations respectively, to better distinguish the non-GAAP financial measures from the comparable GAAP measures and better reflect the purpose of the measures. The composition of the measures remains unchanged and therefore no prior periods were revised.

#### 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) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Cash operating costs are calculated by adjusting Oil Sands segment OS&G expense for i) non-production costs that management believes do not relate to production performance, including, but not limited to, share-based compensation adjustments, research costs, safe-mode costs associated with the deferral of capital projects, additional costs incurred in response to the COVID-19 pandemic, adjustments to reflect the cost of internal transfers in the receiving asset at the cost of production and the expense recorded as part of a non-monetary arrangement involving a third-party processor; ii) revenues associated with excess capacity, including excess power generated and sold that is recorded in operating revenue; and iii) project startup costs. Oil Sands operations and Syncrude production volumes are gross of internally consumed diesel and feedstock transfers between assets through the interconnecting pipelines. Oil Sands operations, Fort Hills and Syncrude cash operating costs are reconciled in the Segment Results and Analysis – Oil Sands section of this MD&A. Management uses cash operating costs to measure operating performance.

(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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 from cogeneration units.

(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reflects other E&P assets, such as Libya, for which netbacks are not provided.

(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reflects adjustments for general and administrative costs not directly attributed to production.

(7) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reflects adjustments for intersegment marketing fees.

(8) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Refinery production is the output of the refining process and differs from crude oil processed as a result of volumetric adjustments for non-crude feedstock, volumetric gain associated with the refining process and changes in unfinished product inventories.

(9) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Rack forward operating revenues, other income less purchases of crude oil and products.

(10) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Rack forward operating expense reflects operating, selling and general expenses associated with retail and wholesale operations.

(11) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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) &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 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
\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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.
