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.

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.

Adjusted Operating Earnings Reconciliation⁽¹⁾

(1) Adjusted operating earnings is a non-GAAP financial measure. 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 Financial Measures section of this news release.
(2) 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.

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) 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.

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 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.

Non-GAAP Financial Measures

Certain financial measures in this news release - namely adjusted funds from operations, adjusted operating earnings, net debt, last-in, first-out (LIFO) inventory valuation methodology and free funds flow and related per share or per barrel amounts - 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 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.

Adjusted Operating Earnings

Adjusted operating earnings is a non-GAAP financial measure that adjusts net earnings for significant items that are not indicative of operating performance. Management uses adjusted operating earnings to evaluate operating performance because management believes it provides better comparability between periods. Adjusted operating earnings is reconciled to net earnings in the news release above.

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. Comparative periods have been revised to reflect this change.

Adjusted Funds From (Used In) Operations

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

(1) 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 funds from (used in) operations. Comparative periods have been revised to reflect this change. See the Income Tax section of the Q4 Report for a discussion on income taxes.

See the Income Tax section of the Q4 Report for a discussion on income taxes.

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).

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.

(1) Excludes capital expenditures related to assets held for sale of $40 million in the fourth quarter of 2022 and $133 million in the first twelve months of 2022.

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.

Legal Advisory - BOEs

Certain natural gas volumes have been converted to barrels of oil equivalent (boe) on the basis of one barrel to six thousand cubic feet. Any figure presented in boe may be misleading, particularly if used in isolation. A conversion ratio of one bbl of crude oil or natural gas liquids to six thousand cubic feet 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, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

(1) 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.
(2) 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.
