TABLE OF CONTENTS

refinery production in Refining and Marketing (R&M). Adjusted operating earnings were also impacted by a weakening of benchmark pricing in both periods, resulting in an increased realization of intersegment profit in the current quarter compared to the prior year quarter.

•

Suncor’s net earnings were $2.820 billion ($2.18 per common share) in the fourth quarter of 2023, which included a $1.125 billion non-cash gain as a result of the acquisition of TotalEnergies EP Canada Ltd. (TotalEnergies Canada), compared to $2.741 billion ($2.03 per common share) in the prior year quarter. In addition to the factors impacting adjusted operating earnings, net earnings for the fourth quarter of 2023 and the prior year quarter were impacted by the reconciling items shown in the table above.

•

Adjusted funds from operations were $4.034 billion ($3.12 per common share) in the fourth quarter of 2023, compared to $4.189 billion ($3.11 per common share) in the prior year quarter, and were influenced by the same factors impacting adjusted operating earnings, as well as one-time tax benefit of approximately $880 million relating to the acquisition of TotalEnergies Canada in the fourth quarter of 2023.

•

Suncor’s total operating, selling and general (OS&G) expenses were $3.395 billion in the fourth quarter of 2023, compared to $3.556 billion in the prior year quarter, with the decrease primarily due to lower commodity costs, primarily natural gas, decreased share-based compensation expenses and the impacts of the sale of the U.K. E&P portfolio. The decrease in OS&G was partially offset by increased operating expenses associated with the company’s additional working interests in Fort Hills acquired in the first and fourth quarters of 2023.

•

As at December 31, 2023, Suncor’s net debt was $13.678 billion, an increase of $683 million compared to September 30, 2023, primarily due to a long-term debt issuance and a net increase in leases associated with the Fort Hills acquisition during the quarter, and a decrease in cash and cash equivalents being partially offset by a decrease in short-term indebtedness.

“Fourth quarter operational performance was exceptionally strong and contained several production records, including record Oil Sands production, record gross production at Fort Hills and the second-highest quarterly upstream production in our company’s history,” said Kruger. “These results demonstrate how our heightened focus on the fundamentals translates to delivering exceptional performance and meeting our commitments.”

•

Total Oil Sands bitumen production increased in the fourth quarter of 2023 compared to the prior year quarter, primarily due to the company’s increased working interest and strong bitumen production at Fort Hills, partially offset by decreased bitumen production at Oil Sands Base and Firebag, as a result of planned turnaround and maintenance activities.

•

The company’s net synthetic crude oil (SCO) production was 475,700 bbls/d in the fourth quarter of 2023, compared to 517,500 bbls/d in the prior year quarter, reflecting significant planned turnaround activities at Oil Sands Base Upgrader 2 that were completed in the first part of the fourth quarter of 2023. Oil Sands Base upgrader utilization was 83% in the fourth quarter of 2023, compared to 93% in the prior year quarter. Syncrude upgrader utilization was 101% in the fourth quarter of 2023, compared to 99% in the prior year quarter.

TABLE OF CONTENTS

•

Internal bitumen transfers reached 45,300 bbls/d in the fourth quarter of 2023, demonstrating the increased level of integration within Suncor’s regional Oil Sands assets. The increase was primarily driven by 41,800 bbls/d of bitumen transferred from Fort Hills to upgrading at Oil Sands Base, taking advantage of the yield uplift from Fort Hills barrels.

•

The company’s saleable non-upgraded bitumen production increased to 281,700 bbls/d in the fourth quarter of 2023, compared to 170,600 bbls/d in the prior year quarter, reflecting the company’s increased working interest and strong production at Fort Hills, as well as increased In Situ and Fort Hills bitumen production sent to market in the current quarter due to lower upgrader availability as a result of the planned turnaround at Oil Sands Base Upgrader 2.

•

E&P production during the fourth quarter of 2023 decreased compared to the prior year quarter, primarily due to the divestment of the company’s U.K. portfolio.

•

Refinery crude throughput was 455,900 bbls/d and refinery utilization was 98% in the fourth quarter of 2023, compared to 440,000 bbls/d and 94% in the prior year quarter, reflecting strong utilization across all refineries in the current quarter, and the impact of unplanned maintenance in the prior year quarter.

•

Refined product sales were 575,500 bbls/d in the fourth quarter of 2023, compared to 548,200 bbls/d in the prior year quarter, with the increase due to higher refinery production, partially offset by a larger build of refined product inventory in the current quarter compared to the prior year quarter.

Corporate and Strategy Updates

•

Closed purchase of TotalEnergies’ Canadian operations. On November 20, 2023, Suncor completed the acquisition of TotalEnergies Canada, which held the remaining 31.23% working interest in Fort Hills, for $1.468 billion before closing adjustments and other closing costs, making Suncor the sole owner of Fort Hills. The effective date of the transaction was April 1, 2023.

•

Terra Nova return to production. The Terra Nova Floating, Production, Storage and Offloading vessel safely restarted production in the fourth quarter of 2023, with production expected to continue ramping up in the beginning of 2024.

•

Quarterly dividend increase. In the fourth quarter of 2023, Suncor’s Board of Directors approved a quarterly dividend of $0.545 per share, an increase of approximately 5% over the prior quarter dividend.

Corporate Guidance Updates

There have been no changes to the corporate guidance ranges previously issued on December 5, 2023.

For further details and advisories regarding Suncor’s 2024 corporate guidance, see www.suncor.com/guidance.

Normal Course Issuer Bid (NCIB)

Subsequent to the fourth quarter of 2023, the Toronto Stock Exchange (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 26, 2024, and ending February 25, 2025, Suncor may purchase for cancellation up to 128,700,000 common shares, which is equal to approximately 10% of Suncor’s public float of 1,287,130,400 common shares as of February 12, 2024. On February 12, 2024, Suncor had 1,287,461,183 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, Suncor agreed that it would not purchase more than 132,900,000 common shares between February 17, 2023, and February 16, 2024. Between February 17, 2023, and February 16, 2024, and pursuant to Suncor’s previous NCIB, Suncor repurchased 47,106,802 shares on the open market for approximately $2.0 billion, at a weighted average price of $42.87 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% (1,970,790 common shares) of the average daily trading volume of Suncor’s common shares on the TSX during the previous six-month period (7,883,161 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 26, 2024.

TABLE OF CONTENTS

FOURTH QUARTER DISCUSSION

Suncor’s adjusted operating earnings were $1.635 billion ($1.26 per common share) in the fourth quarter of 2023, compared to $2.432 billion ($1.81 per common share) in the prior year quarter, with the decrease primarily due to lower crude oil and refined product realizations reflecting a weaker business environment in the current quarter, and decreased sales volumes in E&P, partially offset by lower income taxes, increased sales volumes in Oil Sands and increased refinery production in Refining and Marketing (R&M). Adjusted operating earnings were also impacted by a weakening of benchmark pricing in both periods, resulting in an increased realization of intersegment profit in the current quarter compared to the prior year quarter.

Adjusted Funds from Operations and Cash Flow Provided by Operating Activities

Adjusted funds from operations were $4.034 billion ($3.12 per common share) in the fourth quarter of 2023, compared to $4.189 billion ($3.11 per common share) in the prior year quarter, and were influenced by the same factors impacting adjusted operating earnings, as well as a one-time tax benefit of approximately $880 million relating to the acquisition of TotalEnergies Canada in the fourth quarter of 2023.

Cash flow provided by operating activities, which includes changes in non-cash working capital, was $4.318 billion ($3.34 per common share) in the fourth quarter of 2023, compared to $3.924 billion ($2.91 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 source of cash associated with the company’s working capital balances in the current quarter compared to a use of cash in the prior year quarter. The source of cash in the fourth quarter of 2023 was primarily due to lower accounts receivable balances, as a result of a decrease in benchmark commodity prices during the quarter, partially offset by lower current income taxes payable, and a decrease in accounts payable and accrued liabilities.

(1)

The company revised certain commodity costs to align with the current period presentation. For the first six months of 2023, commodity costs were decreased and operations, selling and corporate costs were increased by $41 million, with no effect on total OS&G expenses.

(2)

In the fourth quarter of 2023, share-based compensation expense of $75 million included $27 million recorded in the Oil Sands segment, $2 million recorded in the E&P segment, $10 million recorded in the R&M segment and $36 million recorded in the Corporate and Eliminations segment. The fourth quarter of 2022 share-based compensation expense of $183 million included $76 million recorded in the Oil Sands segment, $5 million recorded in the E&P segment, $28 million recorded in the R&M segment and $74 million recorded in the Corporate and Eliminations segment. Other primarily includes costs associated with investments in the company’s digital transformation and net-zero greenhouse gas emissions objective, and a $275 million restructuring charge related to workforce reduction plans recorded in the second quarter of 2023.

The decrease in OS&G expenses in the fourth quarter of 2023 compared to the prior year quarter was primarily due to lower commodity costs, primarily natural gas, decreased share-based compensation expenses, and the impacts of the sale of the U.K. E&P portfolio. The decrease in OS&G was partially offset by increased operating expenses associated with the company’s additional working interests in Fort Hills acquired in the first and fourth quarters of 2023. The company’s exposure to commodity costs is partially mitigated by revenue from power sales that are recorded in operating revenues.

(1)

Bitumen production from Oil Sands Base is upgraded, while bitumen production from In Situ operations and Fort Hills is either upgraded or sold as bitumen, with SCO and diesel yields of approximately 79% of bitumen feedstock input. Nearly all bitumen produced at Syncrude is upgraded to sweet SCO and a small amount of diesel at an approximate yield of 85%.

(2)

Upgrader utilization rates are calculated using total upgraded production, inclusive of internally consumed diesel and internal transfers.

(3)

Both Oil Sands operations and Syncrude produce diesel, which is internally consumed in mining operations. In addition, Fort Hills and Syncrude use internally produced diesel from Oil Sands Base. In the fourth quarter of 2023, Oil Sands operations production volumes included 12,900 bbls/d of internally consumed diesel, of which 7,600 bbls/d was consumed at Oil Sands Base, 4,100 bbls/d was consumed at Fort Hills and 1,200 bbls/d was consumed at Syncrude. Syncrude production volumes included 2,900 bbls/d of internally consumed diesel.

(4)

Internal feedstock transfers between Oil Sands operations and Syncrude are included in SCO and diesel production volumes. In the fourth quarter of 2023, Oil Sands operations production included 4,100 bbls/d of SCO that were transferred to Suncor’s share of Syncrude.

(5)

Internal feedstock transfers between Oil Sands operations and Syncrude are included in bitumen production volumes. In the fourth quarter of 2023, Oil Sands operations production included 2,100 bbls/d of bitumen that were transferred to Suncor’s share of Syncrude. Syncrude production included 1,400 bbls/d of bitumen that were transferred to Oil Sands Base.

(6)

Internal feedstock transfers from Fort Hills to Oil Sands operations are included in bitumen production volumes. In the fourth quarter of 2023, Fort Hills production included 41,800 bbls/d of bitumen that was transferred to Oil Sands Base.

Total Oil Sands bitumen production increased in the fourth quarter of 2023 compared to the prior year quarter, primarily due to the company’s increased working interest and strong bitumen production at Fort Hills, partially offset by decreased bitumen production at Oil Sands Base and Firebag as a result of planned turnaround and maintenance activities.

The company’s net SCO production was 475,700 bbls/d in the fourth quarter of 2023, compared to 517,500 bbls/d in the prior year quarter, reflecting significant planned turnaround activities at Oil Sands Base Upgrader 2 that were completed in the first part of the fourth quarter of 2023. Oil Sands Base upgrader utilization was 83% in the fourth quarter of 2023, compared to 93% in the prior year quarter. Syncrude upgrader utilization was 101% in the fourth quarter of 2023, compared to 99% in the prior year quarter.

Oil Sands price realizations decreased in the fourth quarter of 2023 from the prior year quarter, in line with the decrease in crude oil benchmark prices and the impact of weaker SYN-WTI differentials in the current quarter, partially offset by the narrowing of heavy crude oil differentials and a weaker Canadian dollar in relation to the U.S. dollar.

Royalties

Royalties for the Oil Sands segment decreased in the fourth quarter of 2023 compared to the prior year quarter, primarily due to lower annual royalty rates as a result of lower crude benchmark prices, and lower bitumen production at Oil Sands Base and Firebag, partially offset by the company’s increased working interest, and increased bitumen production, at Fort Hills.

Expenses and Other Factors

Total Oil Sands operating expenses decreased in the fourth quarter of 2023 compared to the prior year quarter, primarily due to lower commodity costs, primarily natural gas prices, and decreased share-based compensation expenses, partially offset by increased operating expenses associated with the company’s additional working interests in Fort Hills acquired in the first and fourth quarters of 2023. See the Cash Operating Costs section below for additional details regarding cash operating costs and a breakdown of non-production costs by asset.

In the fourth quarter of 2023, DD&A expense was higher compared to the prior year quarter, primarily due to increased depreciation related to the company’s asset retirement obligation asset, and the company’s increased working interest in Fort Hills, as well as higher derecognition charges of property, plant and equipment in the current quarter.

Financing expense and other, which includes other income, adjusted for the $1.125 billion non-cash gain on acquisition, increased in the fourth quarter of 2023 compared to the prior year quarter. The increase was primarily due to increased accretion expense resulting from asset retirement obligations and increased interest on leases as a result of net leases assumed with the Fort Hills acquisitions in 2023, partially offset by a provision reversal related to the company’s arrangement involving a third-party byproduct processor.

Represents excess power revenue from cogeneration units that is recorded in operating revenues. Oil Sands operations excess power capacity and other also includes, but is not limited to, the natural gas expense recorded as part of a non-monetary arrangement involving a third-party processor.

Oil Sands operations cash operating costs per barrel(1) were $30.80 in the fourth quarter of 2023, compared to $28.35 in the prior year quarter, with the increase primarily due to a higher proportion of Fort Hills bitumen being directed to upgrading at Oil Sands Base and a decrease in excess power revenues resulting from significantly lower power prices, partially offset by lower natural gas prices and increased production.

Fort Hills cash operating costs per barrel(1) were $28.10 in the fourth quarter of 2023, compared to $37.10 in the prior year quarter, with the decrease due to higher production volumes and lower natural gas prices, partially offset by increased mining activity associated with the mine improvement plan and a decrease in excess power revenues resulting from significantly lower power prices.

Syncrude cash operating costs per barrel(1) were $33.85 in the fourth quarter of 2023, compared to $34.60 in the prior year quarter, with the decrease primarily due to lower natural gas prices and other commodity costs, partially offset by increased mining activity in the current period.

Production volumes for E&P Canada were 45,300 bbls/d in the fourth quarter of 2023, compared to 49,100 bbls/d in the prior year quarter, with the decrease primarily due to natural declines, partially offset by the ramp up of production at Terra Nova in the current quarter.

Production volumes for E&P International were 5,400 boe/d in the fourth quarter of 2023, compared to 25,900 boe/d in the prior year quarter, with the decrease primarily due the divestment of the company’s U.K. portfolio in the second quarter of 2023.

Total E&P sales volumes were 29,200 boe/d in the fourth quarter of 2023, compared to 75,100 boe/d in the prior year quarter, primarily due to the same factors that impacted production volumes, as well as a larger build of inventory in E&P Canada in the fourth quarter of 2023 compared to the prior year quarter, associated with the timing of cargo sales at year-end, and a draw of inventory in E&P International in the prior year quarter.

E&P International price realizations exclude Libya.

E&P price realizations decreased in the fourth quarter of 2023 from the prior year quarter, in line with the decrease in benchmark prices for Brent crude, partially offset by weaker foreign exchange rates.

Royalties

E&P royalties, excluding the impact of Libya in the fourth quarter of 2023, were lower compared to the prior year quarter primarily due to the decrease in sales volumes.

Expenses and Other Factors

Operating and transportation expenses decreased in the fourth quarter of 2023 compared to the prior year quarter primarily due to the divestment of the company’s U.K. portfolio, a build of inventory in the current quarter, and a one-time transportation provision recorded in the prior year quarter.

DD&A and exploration expense for the fourth quarter of 2023 decreased compared to the prior year quarter primarily due to lower sales volumes and the divestment of the company’s U.K. portfolio.

Financing expense and other decreased in the fourth quarter of 2023 compared to the prior year quarter primarily due to the impact of insurance settlements in the prior year quarter.

Planned Maintenance Update for Operated Assets

There are no significant planned maintenance events scheduled for the first quarter of 2024.

R&M adjusted operating earnings in the fourth quarter of 2023 were $598 million, compared to $1.529 billion in the prior year quarter. The decrease in adjusted operating earnings was primarily due to lower benchmark crack spreads in the current quarter compared to the prior year quarter, partially offset by increased refinery production.

TABLE OF CONTENTS

Refining and Marketing Gross Margins(1)

Refining and marketing gross margins were influenced by the following:

•

On a LIFO(2) basis, Suncor’s refining and marketing gross margin decreased to $47.05/bbl in the fourth quarter of 2023, from $69.40/bbl in the prior year quarter, primarily due to lower benchmark crack spreads, partially offset by improved margin capture. In the fourth quarter of 2023, on a LIFO basis, Suncor’s refining and marketing gross margin represents 103% margin capture compared to Suncor’s 5-2-2-1 index.

•

On a FIFO basis, Suncor’s refining and marketing gross margin decreased to $37.45/bbl in the fourth quarter of 2023, from $59.30/bbl in the prior year quarter, due to the same factors discussed above, in addition to FIFO inventory valuation impacts. In the fourth quarter of 2023, the FIFO method of inventory valuation, relative to an estimated LIFO(2) accounting method, resulted in a loss of $431 million on the decrease in crude oil benchmarks. In the prior year quarter FIFO resulted in a loss of $439 million, for a favourable quarter-over-quarter impact of $8 million.

Expenses and Other Factors

Operating and transportation expenses increased in the fourth quarter of 2023 compared to the prior year quarter, due to increased maintenance and sales and marketing costs in the current quarter, partially offset by lower natural gas and other commodity input costs, and decreased share-based compensation expenses.

Refining operating expense per barrel(1) was $7.65 in the fourth quarter of 2023, compared to $7.90 in the prior year quarter, with the decrease primarily due to lower commodity input costs and higher refinery production, partially offset by increased maintenance costs and inflationary impacts.

Planned Maintenance

Planned maintenance activities have commenced at the company’s Commerce City refinery, and are expected to be completed in the first quarter of 2024. Planned turnaround maintenance is scheduled to commence at the company’s Montreal refinery in the first quarter of 2024 and is expected to be completed in the second quarter of 2024. The impact of these maintenance events have been reflected in the company’s 2024 guidance.

Corporate incurred an adjusted operating loss of $341 million in the fourth quarter of 2023, compared to $482 million in the prior year quarter. The decreased loss was primarily attributable to an operational foreign exchange gain in the fourth quarter of 2023, compared to a loss in the prior year quarter. The decreased loss was also driven by a lower share-based compensation expense, decreased spend in low-carbon fuel development projects compared to the prior year quarter, and increased costs associated with the early redemption of long-term debt in the prior year quarter. Suncor capitalized $70 million of its borrowing costs in the fourth quarter of 2023, as part of the cost of major development assets and construction projects in progress, compared to $44 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 2023, the company realized $299 million of intersegment profit, compared to $100 million in the prior year quarter. The realization of intersegment profit was primarily driven by a weakening in benchmark pricing in both periods.

Corporate and Eliminations adjusted funds from operations were $10 million for the fourth quarter of 2023, compared to funds used in operations of $273 million in the fourth quarter of 2022, and were influenced by the same factors impacting adjusted operating loss, excluding the impact of share-based compensation expense and increased costs associated with the early redemption of long-term debt in the fourth quarter of 2022.

TABLE OF CONTENTS

FOURTH QUARTER DISCUSSION

During the fourth quarter of 2023, the company incurred $1.482 billion of capital expenditures, excluding capitalized interest, compared to $1.258 billion in the prior year quarter. The increase was primarily driven by increased economic investments at Oil Sands Base, related to the new cogeneration facility, at In Situ, related to well pad investments, at Syncrude, related to the Mildred Lake West Extension mining project, and at E&P, related to increased development work at the West White Rose Project in the current period. This was partially offset by decreased asset sustainment and maintenance capital expenditures at Oil Sands Base.

Activity in the fourth quarter of 2023 is summarized by business unit below.

Oil Sands

Oil Sands Base capital expenditures were $553 million in the fourth quarter of 2023 and were primarily focused on significant planned turnaround activities at Upgrader 2 as well as tailings development. Economic investment expenditures were primarily focused on progressing the investment in low-carbon power cogeneration by replacing the coke-fired boilers with a new cogeneration facility.

In Situ capital expenditures were $136 million in the fourth quarter of 2023 and were primarily directed towards economic investment activities focused on the ongoing design and construction of well pads to develop additional reserves that are expected to maintain existing production levels.

Fort Hills capital expenditures were $75 million in the fourth quarter of 2023 and were directed towards mine and tailings development to support ongoing operations, including expenditures to progress the execution of the mine improvement plan.

Syncrude capital expenditures were $244 million in the fourth quarter of 2023 and were primarily directed towards planned maintenance activities, mine equipment replacements and tailings development. Economic investment expenditures were directed towards progressing the Mildred Lake West Extension mining project.

Exploration and Production

E&P capital and exploration expenditures were $152 million in the fourth quarter of 2023 and were focused on economic investment projects, primarily development work on the West White Rose Project, and the completion of the Terra Nova Asset Life Extension Project.

Refining and Marketing

R&M capital expenditures were $304 million in the fourth quarter of 2023 and were primarily related to the company’s planned maintenance program as well as strengthening the company’s sales and marketing business, including the enhancement of its retail operations.

Corporate and Eliminations

Corporate and Eliminations capital expenditures were $18 million in the fourth quarter of 2023 and were primarily directed towards investment in digital technologies.

For the twelve months ended December 31, 2023, there were no impairments or impairment reversals. As a result, ROCE excluding impairments was equal to ROCE. ROCE would have been 13.6% for the twelve months ended December 31, 2023, excluding the impact of the $1.125 billion non-cash gain on acquisition of TotalEnergies Canada. ROCE would have been 22.9% for the twelve months ended December 31, 2022, excluding the impact of the impairment reversal of $715 million ($542 million after-tax) and impairment of $70 million ($47 million after-tax) in the second quarter of 2022 and the impact of the impairment of $3.397 billion ($2.586 billion after-tax) in the third quarter of 2022.

Capital Resources

Suncor’s capital resources consist primarily of cash flow provided by operating activities, cash and cash equivalents, and available lines of credit. Suncor’s management believes the company will have the capital resources required to fund its planned 2024 capital spending program of $6.3 billion to $6.5 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 several factors, including commodity prices, production, sales volumes, refining and marketing gross margins, operating expenses, taxes, royalties and foreign exchange rates.

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

Available Sources of Liquidity

For the three months ended December 31, 2023, cash and cash equivalents decreased to $1.729 billion from $2.432 billion as at September 30, 2023. The use of cash in the fourth quarter of 2023 was due to a net decrease in short-term and long-term indebtedness, including the impacts of the acquisition of an additional 31.23% working interest in Fort Hills, the company’s capital and exploration expenditures, the payment of dividends and the repurchase of Suncor’s common shares under its NCIB exceeding the company’s cash flow provided by operating activities.

For the twelve months ended December 31, 2023, cash and cash equivalents decreased to $1.729 billion from $1.980 billion as at December 31, 2022. The use of cash in 2023 was due to the company’s capital and exploration expenditures, a net decrease in short-term and long-term indebtedness, including the impacts of the acquisition of an additional 45.89% working interest in Fort Hills, the payment of dividends and the repurchase of Suncor’s common shares under its NCIB exceeding the company’s cash flow provided by operating activities and proceeds from the sale of its U.K. E&P portfolio and its wind and solar assets.

As at December 31, 2023, the weighted average days to maturity of the company’s short-term investment portfolio was approximately 20 days.

As at December 31, 2023, available credit facilities for liquidity purposes were $4.957 billion, compared to $2.900 billion as at December 31, 2022. The increase in available credit facilities was due to a decrease in short-term indebtedness, partially offset by a reduction in the size of the company’s syndicated credit facilities. In the second quarter of 2023, the company extended the maturity of its syndicated credit facilities from June 2024 and June 2025 to June 2026, and reduced the size of its $3.0 billion tranche to $2.8 billion.

Financing Activities

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

FOURTH QUARTER DISCUSSION

During the fourth quarter of 2023, the company issued $1.0 billion principal amount of 5.60% senior unsecured medium term notes and $500 million principal amount of 5.40% senior unsecured medium term notes, due on November 17, 2025, and November 17, 2026, respectively, to finance the acquisition of TotalEnergies Canada.

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. As at December 31, 2023, total debt to total debt plus shareholders’ equity was 26.3% (December 31, 2022 – 28.4%). The company also continues to be in compliance with all operating covenants under its debt agreements.

Share Repurchases

During the first quarter of 2023, the TSX accepted a notice filed by Suncor to renew its NCIB to repurchase the company’s common shares through the facilities of the TSX, NYSE 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 defined in the TSX Company Manual) as at February 3, 2023. On February 3, 2023, Suncor had 1,330,006,760 common shares issued and outstanding.

Subsequent to the fourth quarter of 2023, 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, NYSE and/or alternative trading systems. The notice provides that, beginning February 26, 2024, and ending February 25, 2025, Suncor may purchase for cancellation up to 128,700,000 common shares, which is equal to approximately 10% of Suncor’s public float as of February 12, 2024. On February 12, 2024, Suncor had 1,287,461,183 common shares issued and outstanding.

Between February 17, 2023, and February 16, 2024, pursuant to Suncor’s previous NCIB, Suncor repurchased 47,106,802 common shares on the open market, representing the equivalent of 3.5% of its common shares as at February 3, 2023, for $2.019 billion, at a weighted average price of $42.87 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. The company believes that, depending on the trading price of its common shares and other relevant factors, repurchasing its own shares represents an attractive investment opportunity and is in the best interests of the company and its shareholders. The company does not expect the decision to allocate cash to repurchase shares will affect its long-term strategy.

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 2022 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 2023, the company increased its commitments as a result of the acquisition of an additional 31.23% working interest in Fort Hills. The acquisition of additional working interest is expected to impact the company’s undiscounted future decommissioning and restoration costs, long-term contracts, pipeline capacity and energy service commitments and its commitments associated with leases.

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 2022 annual MD&A and in notes 3 and 5 of Suncor’s audited Consolidated Financial Statements for the year ended December 31, 2022.

Critical Accounting Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates, judgments and assumptions that affect reported assets, liabilities, revenues and expenses, gains and losses, and disclosures of contingencies. These estimates and assumptions are subject to change based on experience and new information. Critical accounting estimates are those that require management to make assumptions about matters that are highly uncertain at the time the estimate is made. Critical accounting estimates are also those estimates that, where a different estimate could have been used or where changes in the estimate that are reasonably likely to occur, would have a material impact on the company’s financial condition, changes in financial condition or financial performance. Critical accounting estimates and judgments are reviewed annually by the Audit Committee of the Board of Directors. A detailed description of Suncor’s critical accounting estimates is provided in note 4 to the audited Consolidated Financial Statements for the year ended December 31, 2022, and in the Accounting Policies and Critical Accounting Estimates section of Suncor’s 2022 annual MD&A.

Financial Instruments

Suncor periodically enters into derivative contracts such as forwards, futures, swaps, options and costless collars to manage exposure to fluctuations in commodity prices and foreign exchange rates, and to optimize the company’s position with respect to interest payments. For more information on Suncor’s financial instruments and the related financial risk factors, see note 27 of the audited Consolidated Financial Statements for the year ended December 31, 2022, note 9 to the unaudited interim Consolidated Financial Statements for the twelve months ended December 31, 2023, and the Financial Condition and Liquidity section of the 2022 annual MD&A.

9. NON-GAAP AND OTHER FINANCIAL MEASURES ADVISORY

Certain financial measures in this document – namely adjusted operating earnings (loss), adjusted funds from (used in) operations, measures contained in ROCE and ROCE excluding impairments and impairment reversals, price realizations, free funds flow, 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.

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.

Bridge Analyses of Adjusted Operating Earnings (Loss)

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

•

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

•

The factor for Price, Margin and Other Revenue includes upstream price realizations before royalties, except for 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.

•

The factor for Royalties excludes the impact of Libya, as royalties in Libya are included in Price, Margin and Other Revenue as described above.

•

The factor for Inventory Valuation is comprised of changes in the FIFO inventory valuation and the realized portion of commodity risk management activities reported in the R&M segment, as well as the impact of the deferral or realization of profit or loss on crude oil sales from the Oil Sands segment to Suncor’s refineries reported in the Corporate and Eliminations segment.

•

The factor for Operating and Transportation Expense includes project startup costs, OS&G expense and transportation expense.

•

The factor for Financing Expense and Other includes financing expenses, other income, operational foreign exchange gains and losses and changes in gains and losses on disposal of assets that are not adjusted operating earnings (loss) adjustments.

•

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

•

The factor for Income Tax includes the company’s current and deferred income tax expense on adjusted operating earnings, changes in statutory income tax rates and other income tax adjustments.

Return on Capital Employed (ROCE) and ROCE Excluding Impairments and Impairment Reversals

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

Adjusted Funds From (Used In) Operations

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

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

Oil Sands Operations, Fort Hills and Syncrude Cash Operating Costs

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

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

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

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

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

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.

TABLE OF CONTENTS

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

Additional risks, uncertainties and other factors that could influence the financial and operating performance of all of Suncor’s operating segments and activities include, but are not limited to, changes in general economic, market and business conditions, such as commodity prices, interest rates and currency exchange rates (including as a result of demand and supply effects resulting from 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; the ability to maintain an optimal debt to cash flow ratio; the success of the company’s marketing and logistics activities using derivatives and other financial instruments; the cost of compliance with current and future environmental laws, including climate change laws; risks relating to increased activism and public opposition to fossil fuels and oil sands; 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;

TABLE OF CONTENTS

(b) Fair Value Hierarchy

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

•

Level 1 consists of instruments with a fair value determined by an unadjusted quoted price in an active market for identical assets or liabilities. An active market is characterized by readily and regularly available quoted prices where the prices are representative of actual and regularly occurring market transactions to assure liquidity.

•

Level 2 consists of instruments with a fair value that is determined by quoted prices in an inactive market, prices with observable inputs or prices with insignificant non-observable inputs. The fair value of these positions is determined using observable inputs from exchanges, pricing services, third-party independent broker quotes and published transportation tolls. The observable inputs may be adjusted using certain methods, which include extrapolation over the quoted price term and quotes for comparable assets and liabilities.

•

Level 3 consists of instruments with a fair value that is determined by prices with significant unobservable inputs. As at December 31, 2023, 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, 2023:

($ millions)	Level 1		Level 2		Level 3		Total Fair Value
Accounts receivable		41		24		—		65

Accounts payable		(51)		(34)		—		(85)
		(10)		(10)		—		(20)

During the fourth quarter of 2023, there were no transfers between Level 1 and Level 2 fair value measurements.

Non-Derivative Financial Instruments

At December 31, 2023, the carrying value of fixed-term debt accounted for under amortized cost was $11.1 billion (December 31, 2022 – $9.8 billion) and the fair value was $11.1 billion (December 31, 2022 – $9.4 billion). The estimated fair value of long-term debt is based on pricing sourced from market data.

10. Asset Transactions and Valuations

Oil Sands
Acquisition of Additional Ownership Interest in Fort Hills:

On February 2, 2023, Suncor completed the acquisition of an additional 14.65% working interest in Fort Hills from Teck Resources Limited (Teck) for $712 million, bringing the company’s working interest in Fort Hills to 68.76%.

Other assets include $3 million of cash and cash equivalents.

The fair values of accounts receivables and accounts payable approximate their carrying values due to the short-term maturity of the instruments. The fair value of materials and supplies inventory approximates book value due to short-term turnover rates. The fair values of property, plant and equipment and the decommissioning provision were determined using an expected future cash flow approach (Level 3 fair value inputs – note 9). Key assumptions used in the calculations were discount rates, forecasted production volumes, commodity prices (including foreign exchange rates), operating costs and capital costs (“forecasted cash flow assumptions”).

The additional 14.65% working interest in Fort Hills contributed $501 million to gross revenues and $22 million net earnings to consolidated net earnings from the acquisition date to December 31, 2023.

Had the acquisition occurred on January 1, 2023, the additional working interest would have contributed an additional $20 million to gross revenues and a $21 million net loss, which would have resulted in gross revenues of $52.2 billion and consolidated net earnings of $8.3 billion for the twelve months ended December 31, 2023.

The proforma information is not necessarily indicative of the results that would have been obtained if the Teck acquisition had actually occurred on January 1, 2023.

Prior to the Teck acquisition, the company updated its long-range plan for Fort Hills, which incorporated lower gross production and increased operating costs per barrel for the next three years. 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 in the third quarter of 2022.

Acquisition of TotalEnergies EP Canada Ltd. and Remaining Working Interest in Fort Hills:

On November 20, 2023, Suncor completed the acquisition of TotalEnergies EP Canada Ltd. (TotalEnergies Canada), which held the remaining 31.23% working interest in Fort Hills, for a purchase price of $1.468 billion before working capital, closing adjustments and other closing costs, making Suncor the sole owner of Fort Hills. The effective date of the transaction was April 1, 2023. The determination of fair value of the preliminary purchase price is based on management’s best estimate as of the closing date.

	Net assets acquired					3 030

The fair values of accounts receivables and accounts payable approximate their carrying values due to the short-term maturity of the instruments. The fair value of inventory was determined using market prices and rates from available pricing sources. The fair values of property, plant and equipment and the decommissioning provision were determined using an expected future cash flow approach (Level 3 fair value inputs – note 9). Key assumptions used in the calculations were discount rates, forecasted production volumes, commodity prices (including foreign exchange rates), operating costs and capital costs (“forecasted cash flow assumptions”). The deferred income tax asset recognized as a result of the acquisition of TotalEnergies Canada involves numerous assumptions made by management and the interpretation of the tax laws applicable to the circumstances surrounding the historical tax positions taken by, and acquisition of, TotalEnergies Canada.

As required when an acquirer achieves control in stages, the previously held interest in Fort Hills has been re-measured to fair value at the acquisition date. The acquisition date fair value of the previously held interest was estimated to be $3.887 billion and the net carrying value of the Fort Hills assets was $3.904 billion. The company recognized a non-cash revaluation loss of its existing interest of $17 million in other income in the consolidated statements of comprehensive income.

Total consideration includes working capital as at April 1, 2023.

Acquisition costs of $12 million, have been charged to operating, selling and general expense in the consolidated statements of comprehensive income for the three and twelve months ended December 31, 2023.

The acquisition of TotalEnergies Canada contributed $148 million to gross revenues and $18 million net earnings to consolidated net earnings from the acquisition date to December 31, 2023.

Had the acquisition occurred on January 1, 2023, TotalEnergies Canada would have contributed an additional $1.1 billion to gross revenues and $71 million to net earnings, which would have resulted in gross revenues of $53.3 billion and consolidated net earnings of $8.4 billion for the twelve months ended December 31, 2023.

The proforma information is not necessarily indicative of the results that would have been obtained if the TotalEnergies Canada acquisition had actually occurred on January 1, 2023.

As part of the acquisition, the company assumed various pipeline commitments and ancillary assets, including the remaining capacity on a regional pipeline, which has been recognized accordingly as an ROU asset in property plant and equipment and long-term lease liability.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Meadow Creek:

During the third quarter of 2023, the company recorded after-tax derecognition charges of $192 million ($253 million before-tax) on its Meadow Creek development properties in the Oil Sands segment as these properties no longer align with the company’s future development plans.

Exploration and Production
Sale of United Kingdom Operations:

During the second quarter of 2023, the company completed the sale of its United Kingdom (U.K.) operations, including its interests in Buzzard and Rosebank located in the U.K. sector of the North Sea, for gross proceeds of $1.1 billion, before closing adjustments and other closing costs, resulting in an after-tax gain on sale of $607 million ($607 million before-tax) including $25 million in foreign exchange gains recognized as a result of the disposal. The U.K. operations are reported within the Exploration and Production segment.

Corporate
Sale of Wind and Solar Assets:

During the first quarter of 2023, the company completed the sale of its wind and solar assets for gross proceeds of $730 million, before closing adjustments and other closing costs, resulting in an after-tax gain on sale of approximately $260 million ($302 million before-tax). The wind and solar assets were reported in the Corporate segment.

11. Provisions

Suncor’s decommissioning and restoration provision increased by $1.8 billion for the twelve months ended December 31, 2023. The increase was primarily due to the increased working interest in Fort Hills (note 10), updated closure estimates, and a decrease in the credit-adjusted risk-free interest rate to 5.20% (December 31, 2022 – 5.50%).

12. Pensions and Other Post-Retirement Benefits

For the twelve months ended December 31, 2023, the actuarial gain on employee retirement benefit plans decreased to $128 million (net of taxes of $42 million). The decrease in the actuarial gain was mainly due to a decrease in discount rate to 4.60% (December 31, 2022 – 5.10%).

Operating Summary Information

Non-GAAP 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, 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 Report). Adjusted funds from (used in) operations and measures contained in ROCE and ROCE excluding impairments and impairment reversals are 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 Quarterly 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.

Oil Sands Operating Netbacks

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

Exploration and Production (E&P) Operating Netbacks

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

Definitions

(1)

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

(2)

Reflects the items not directly attributed to revenues received from the sale of proprietary crude and net non-proprietary activity at its deemed point of sale.

(3)

Reflects adjustments for general and administrative costs not directly attributed to the production of each crude product type, as well as the revenues associated with excess power from cogeneration units.

(4)

Reflects other E&P assets, such as Libya, for which netbacks are not provided.

(5)

Production from the company’s Libya operations has been presented in this document on an economic basis. Revenue and royalties from the company’s Libya operations are presented under the working-interest basis, which is required for presentation purposes in the company’s financial statements. Under the working-interest basis, revenue includes a gross-up amount with offsetting amounts presented in royalties in the E&P segment and income tax expense reported at the total consolidated level.

(6)

Reflects adjustments for general and administrative costs not directly attributed to production.

(7)

Reflects adjustments for intersegment marketing fees.

(8)

Refining production is the output of the refining process and differs from crude oil processed as a result of volumetric adjustment for non-crude feedstock, volumetric gain associated with the refining process, and changes in unfinished product inventories.

TABLE OF CONTENTS

(9)

Rack forward operating revenues, other income less purchases of crude oil and products.

(10)

Rack forward operating expense reflects operating, selling and general expenses associated with retail and wholesale operations.

(11)

Reflects operating, selling and general expenses associated with the company’s ethanol businesses and certain other operating, general and administrative costs not directly attributable to refinery production.

(12)

The custom 5-2-2-1 index is designed to represent Suncor’s Refining and Marketing business based on publicly available pricing data and approximates the gross margin on five barrels of crude oil of varying grades that is refined to produce two barrels of both gasoline and distillate and one barrel of secondary product. The index is a single value that is calculated by taking the product value of refined products less the crude value of refinery feedstock incorporating the company’s refining, product supply and rack forward businesses, but excluding the impact of first-in, first-out accounting. The product value is influenced by New York Harbor 2-1-1 crack, Chicago 2-1-1 crack, WTI benchmarks and seasonal factors. The seasonal factor is an estimate and reflects the location, quality and grade differentials for refined products sold in the company’s core markets during the winter and summer months. The crude value is influenced by SYN, WCS and WTI benchmarks.

Explanatory Notes

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