Note 8. Financial and derivative instruments

Financial instruments

The fair value of the company’s financial instruments is determined by reference to various market data and other appropriate valuation techniques. There are no material differences between the fair value of the company’s financial instruments and the recorded carrying value. At June 30, 2025 and December 31, 2024, the fair value of long-term debt ($3,447 million, excluding finance lease obligations) was primarily a level 2 measurement.

Derivative instruments

The company’s size, strong capital structure and the complementary nature of its business segments reduce the company’s enterprise-wide risk from changes in commodity prices, currency rates and interest rates. In addition, the company uses commodity-based contracts, including derivatives, to manage commodity price risk and to generate returns from trading. Commodity contracts held for trading purposes are presented in the Consolidated statement of income on a net basis in the line "Revenues" and in the Consolidated statement of cash flows in "Cash flows from (used in) operating activities". The company’s commodity derivatives are not accounted for under hedge accounting.

Credit risk associated with the company’s derivative position is mitigated by several factors, including the use of derivative clearing exchanges and the quality of and financial limits placed on derivative counterparties. The company maintains a system of controls that includes the authorization, reporting and monitoring of derivative activity.

The net notional long/(short) position of derivative instruments was:

	As at<br><br>Jun 30	As at Dec 31
thousands of barrels	2025	2024
Crude	4,374	4,260

The current 12-month normal course issuer bid program came into effect June 29, 2025 under which Imperial will continue its existing share purchase program. The program enables the company to purchase up to a maximum of 25,452,248 common shares (5 percent of the total shares on June 15, 2025) which includes shares purchased under the normal course issuer bid from Exxon Mobil Corporation. As in the past, Exxon Mobil Corporation has advised the company that it intends to participate to maintain its ownership percentage at approximately 69.6 percent. Imperial plans to accelerate its share purchases under the normal course issuer bid program, and anticipates repurchasing all remaining allowable shares prior to year end. Purchase plans may be modified at any time without prior notice.

The excess of the purchase cost over the stated value of shares purchased has been recorded as a distribution of earnings reinvested.

The company’s common share activities are summarized below:

Item 2. Management’s discussion and analysis of financial condition and results of operations

Recent business environment

During the second quarter of 2025, the price of crude oil decreased relative to first quarter of 2025, while the Canadian WTI/WCS spread narrowed due to low inventory levels. Industry refining margins improved in the second quarter of 2025, driven by strong seasonal demand.

During 2025, the United States announced a variety of trade-related actions, including the imposition of tariffs on imports from Canada and several other countries. In response, Canada announced its own retaliatory tariffs. Certain tariffs were paused for a period of time but have not been withdrawn, while others have been revised. The global trade environment continues to be volatile. The likelihood of the United States, Canada or their trading partners resuming tariffs, imposing new or revised reciprocal tariffs, export restrictions, or other forms of trade-related sanctions is highly uncertain. Additionally, significant uncertainty exists as to what effects these actions will ultimately have on Imperial, its suppliers and its customers. The company continually monitors the global trade environment and works to mitigate potential impacts.

Net income (loss) factor analysis

millions of Canadian dollars

Price – Average bitumen realizations decreased by $17.20 per barrel, primarily driven by lower marker prices. Synthetic crude oil realizations decreased by $23.71 per barrel, primarily driven by lower WTI and a weaker Synthetic/WTI spread.

Volumes – Higher volumes were primarily driven by the timing of the annual coker turnaround at Syncrude and mine productivity and improved reliability at Kearl.

Royalty – Lower royalties were primarily driven by lower commodity prices.

(a)In the second quarter of 2025, Syncrude gross production included about 4 thousand barrels per day of bitumen and other products (2024 - 2 thousand barrels per day) that were exported to the operator's facilities using an existing interconnect pipeline.

Higher production at Kearl was primarily driven by mine productivity and improved reliability.

Lower production at Cold Lake was primarily driven by production and steam cycle timing, and turnaround impacts partially offset by Grand Rapids solvent-assisted SAGD.

Higher production at Syncrude was primarily driven by the timing of the annual coker turnaround.
