Certain financial measures referred to in this news release (adjusted funds from operations, adjusted operating earnings, free funds flow and net debt) are not prescribed by Canadian generally accepted accounting principles (GAAP).

Calgary, Alberta (February 21, 2024)

Fourth Quarter Highlights

“Our fourth quarter performance can be characterized as finishing the year strong, delivering on commitments, and building momentum coming into 2024,” said Rich Kruger, Suncor’s President and Chief Executive Officer. “Most importantly, the quarter was the safest quarter of the year in what resulted in our safest year ever. In addition, upstream reliability across our operations was at or near record highs, achieving the second highest quarterly total production in the company’s history and the highest quarterly Oil Sands production. Downstream performance was equally strong with refining utilization in the quarter at 98%. Looking ahead, we will continue our intense focus on safety, operational excellence, reliability and profitably to further improve performance and add value for our shareholders.”

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.

Non-GAAP Financial Measures

Certain financial measures in this news release – namely adjusted funds from operations, adjusted operating earnings, free funds flow and net debt, 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.

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 are reconciled to net earnings in the news release above.

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.

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.

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).

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.
