Calgary, Alberta--(Newsfile Corp. - November 29, 2022) - Suncor Energy (TSX: SU) (NYSE: SU) released its 2023 corporate guidance today.

"Over the past several months, our new mining leadership has done an in-depth review of our assets and developed a multi-year plan that will deliver marked improvements in safety, reliability and operational performance," said Kris Smith interim president and chief executive officer. "In addition, we will continue to optimize our assets to drive value and future growth in areas that are complementary to our base business."

Members of the Suncor leadership team will discuss this outlook later today at the Company's previously scheduled Investor Presentation beginning at 11 a.m. MT / 1 p.m. ET. A webcast of the event will be available at Suncor.com.

1) Production ranges for Oil Sands operations, Fort Hills, Syncrude and Exploration and Production are not intended to add to equal Suncor Total Production.

2) Oil Sands operations production includes synthetic crude oil, diesel, and bitumen and excludes Fort Hills PFT bitumen and Syncrude synthetic crude oil production. These ranges reflect the integrated upgrading and bitumen production performance risk.

3) Fort Hills production assumes Suncor's incremental 21.3% share of Fort Hills production acquired from Teck Resources Limited is effective April 1, 2023.

4) Exploration and Production volumes assume UK divestiture takes place effective June 30, 2023.

5) Refinery utilization is based on the following crude processing capacities: Montreal - 137,000 bbls/d; Sarnia - 85,000 bbls/d; Edmonton - 146,000 bbls/d; and Commerce City - 98,000 bbls/d.

6) Capital expenditures exclude capitalized interest of approximately $180 million.

7) Upstream Oil Sands capital expenditure includes approximately $100 million for Suncor's incremental 21.3% share of Fort Hills acquired from Teck Resources Limited, which is assumed to close on April 1, 2023.

8) Balance of capital expenditures represents Asset Sustainment and Maintenance capital expenditures.

In addition, all other statements and information about Suncor's strategy for growth, expected and future expenditures or investment decisions, commodity prices, costs, schedules, production volumes, operating and financial results and the expected impact of future commitments are forward-looking statements. Some of the forward-looking statements may be identified by words like "guidance", "outlook", "will", "expected", "estimated", "focus", "planned", "believe", "anticipate" and similar expressions.

Forward-looking statements are based on Suncor's current expectations, estimates, projections and assumptions that were made by the company in light of its information available at the time the statement was made and consider Suncor's experience and its perception of historical trends, including expectations and assumptions concerning: the accuracy of reserves and resources estimates; the current and potential adverse impacts of the COVID-19 pandemic, including the status of the pandemic and future waves; commodity prices and interest and foreign exchange rates; the performance of assets and equipment; capital efficiencies and cost-savings; applicable laws and government policies; future production rates; the sufficiency of budgeted capital expenditures in carrying out planned activities; the availability and cost of labour, services and infrastructure; the satisfaction by third parties of their obligations to Suncor; the development and execution of projects; and the receipt, in a timely manner, of regulatory and third-party approvals.

Forward-looking statements are not guarantees of future performance and involve a number of risks and uncertainties, some that are similar to other oil and gas companies and some that are unique to Suncor. Suncor's actual results may differ materially from those expressed or implied by its forward- looking statements, so readers are cautioned not to place undue reliance on them.

Assumptions for the Oil Sands operations, Syncrude and Fort Hills 2023 production outlook include those relating to reliability and operational efficiency initiatives that the company has initiated. Assumptions for the Exploration & Production 2023 production outlook include those relating to reservoir performance, drilling results and facility reliability. Factors that could potentially impact Suncor's 2023 corporate guidance include, but are not limited to:

• Bitumen supply. Bitumen supply may be dependent on unplanned maintenance of mine equipment and extraction plants, bitumen ore grade quality, tailings storage and in situ reservoir performance.
• Third-party infrastructure. Production estimates could be negatively impacted by issues with third- party infrastructure, including pipeline or power disruptions, that may result in the apportionment of capacity, pipeline or third-party facility shutdowns, which would affect the company's ability to produce or market its crude oil.
• Performance of recently commissioned facilities or well pads. Production rates while new equipment is being brought into service are difficult to predict and can be impacted by unplanned maintenance.
• Unplanned maintenance. Production estimates could be negatively impacted if unplanned work is required at any of our mining, extraction, upgrading, in situ processing, refining, natural gas processing, pipeline, or offshore assets.
• Planned maintenance events. Production estimates, including production mix, could be negatively impacted if planned maintenance events are affected by unexpected events or are not executed effectively. The successful execution of maintenance and start-up of operations for offshore assets, in particular, may be impacted by harsh weather conditions, particularly in the winter season.
• Commodity prices. Declines in commodity prices may alter our production outlook and/or reduce our capital expenditure plans.
• Foreign operations. Suncor's foreign operations and related assets are subject to a number of political, economic and socio-economic risks.

Non-GAAP Financial Measures

Oil Sands operations cash operating costs, Fort Hills cash operating costs and Syncrude cash operating costs are not prescribed by Canadian generally accepted accounting principles ("GAAP"). These non-GAAP financial measures are included because management uses the information to analyze business performance, including on a per barrel basis, 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. These non-GAAP financial measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. These non-GAAP financial measures are defined in the Non-GAAP Financial Measures Advisory section of the MD&A and, for the period ended September 30, 2022, are reconciled to the comparable GAAP measure in the MD&A, and each such reconciliation are incorporated by reference herein. Oil Sands operations cash operating costs of $30.00 - $33.00 (US $22.80 - $25.10) per barrel is based on the assumptions that: (i) Suncor will produce 385,000 - 425,000 bbls/d at Oil Sands operations (of which 290,000 - 310,000 bbls/d will be synthetic crude oil and 95,000 - 115,000 will be bitumen); and (ii) natural gas used at Suncor's Oil Sands operations (AECO - C Spot ($CAD)) will be priced at an average of $5.00/GJ over 2023. Fort Hills cash operating costs of $33.00 - $36.00 (US $25.10 - $27.40) per barrel is based on the assumptions that: (i) Fort Hills production (net to Suncor) will be 90,000 - 100,000 bbls/d; and (ii) natural gas used at Fort Hills (AECO - C Spot ($CAD)) will be priced at an average of $5.00/GJ over 2023. Syncrude cash operating costs of $39.00 - $43.00 (US $29.60 - $32.70) per barrel is based on the assumptions that: (i) Syncrude will produce 175,000 - 190,000 bbls/d of synthetic crude oil (net to Suncor); and (ii) natural gas used at Syncrude (AECO - C Spot ($CAD)) will be priced at an average of $5.00/GJ over 2023. The Syncrude cash operating costs per barrel and Fort Hills cash operating costs per barrel measures may not be fully comparable to similar information calculated by other entities (including Suncor's Oil Sands operations cash operating costs per barrel) due to differing operations.

The MD&A, together with Suncor's Annual Information Form and Annual Report to Shareholders each dated February 23, 2022, its Form 40-F dated February 24, 2022, and other documents it files from time to time with securities regulatory authorities describe the risks, uncertainties, material assumptions and other factors that could influence actual results and such factors are incorporated herein by reference.
