Non-GAAP Financial Measures

Certain financial measures used in this news release, namely normalized free funds flow, are not prescribed by GAAP. Non-GAAP measures presented herein do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other companies. Therefore, these non-GAAP measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. All non-GAAP measures are included because management uses the information to analyze business and performance, leverage and liquidity and therefore may be considered useful information by investors.

Free funds flow is calculated by taking adjusted funds from operations and subtracting capital expenditures, including capitalized interest. Normalized free funds flow is calculated by taking free funds flow and normalizing it for a US$75 WTI price. Normalized free funds flow is defined and reconciled in Suncor’s report to shareholders for the fourth quarter of 2024, dated February 5, 2025.

All reconciliations noted above are in the Non-GAAP financial measures advisory section of the applicable quarterly report and/or MD&A, each of which is available on the company’s SEDAR profile available at www.sedarplus.ca and each such reconciliation is incorporated by reference herein.

Corporate WTI breakeven price is a supplementary financial measure that represents the U.S. dollar WTI price per barrel that is equal to Suncor’s operating costs, dividend payment amount and sustaining capital on a per barrel basis. Management uses corporate WTI breakeven price to measure the company’s performance and believes it provides investors with important information regarding the efficiency and profitability of Suncor’s operations.
