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 September 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>Sep 30 As at Dec 31
thousands of barrels 2025 2024
Crude (1,284) 4,260

The current 12-month normal course issuer bid program came into effect June 29, 2025 under which Imperial has continued 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 continue its acceleration of 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:

Note 11. Miscellaneous financial information

Restructuring charges

On September 29, 2025, the company announced restructuring plans to improve its performance by centralizing additional corporate and technical activities in global business and technology centres. The restructuring plans include a program of targeted workforce reductions. The program, which is expected to be substantially completed by the end of 2027, involves involuntary employee separations. In Q3 2025, the company recorded charges of $330 million, before-tax, consisting primarily of restructuring costs associated with announced workforce reduction programs. These costs are captured in “Selling and general” on the Consolidated statement of income and reported in the Corporate and other segment.

The following table summarizes the reserves and charges related to the workforce reduction program, which are recorded in "Accounts payable and accrued liabilities" and "Other long-term obligations" on the Consolidated balance sheet.

Campus impairment

In Q3 2025, the Corporate and other segment included a non-cash impairment charge of $406 million, before-tax, in conjunction with the company signing an agreement to sell the Calgary Imperial campus. The impairment is reflected in "Depreciation and depletion (includes impairments)" on the Consolidated statement of income, and in "Property, plant and equipment - net" on the Consolidated balance sheet. The Calgary Imperial campus has been classified as an asset held for sale and is reflected in "Property, plant and equipment - net" on the Consolidated balance sheet, with a total asset value of approximately $60 million. It is anticipated that the transaction will close in 2025.

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

Recent business environment

During the third quarter of 2025, the price of crude oil increased slightly relative to second quarter of 2025, while the Canadian WTI/WCS spread remained relatively flat with the second quarter of 2025. Industry refining margins improved in the third quarter of 2025, driven by strong seasonal demand and global diesel supply disruptions.

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. Despite the current uncertainty as to what effects these actions will ultimately have on Imperial, its suppliers and its customers, the company does not anticipate any material near-term financial impacts.

Price – Average bitumen realizations decreased by $9.02 per barrel, primarily driven by lower marker prices partially offset by narrowing WTI/WCS spread. Synthetic crude oil realizations decreased by $13.29 per barrel, primarily driven by lower WTI and a weaker Synthetic/WTI spread.

Volume – Inventory impacts partially offset by higher production.

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

Non-GAAP financial measures and other specified financial measures

Certain measures included in this document are not prescribed by U.S. Generally Accepted Accounting Principles (GAAP). These measures constitute "non-GAAP financial measures" under Securities and Exchange Commission Regulation G and Item 10(e) of Regulation S-K, and "specified financial measures" under National Instrument 52-112 Non-GAAP and Other Financial Measures Disclosure of the Canadian Securities Administrators.

Reconciliation of these non-GAAP financial measures to the most comparable GAAP measure, and other information required by these regulations, have been provided. Non-GAAP financial measures and specified financial measures are not standardized financial measures under GAAP and do not have a standardized definition. As such, these measures may not be directly comparable to measures presented by other companies, and should not be considered a substitute for GAAP financial measures.

Net income (loss) excluding identified items

Net income (loss) excluding identified items is a non-GAAP financial measure that is total net income (loss) excluding individually significant non-operational events with an absolute corporate total earnings impact of at least $100 million in a given quarter. The net income (loss) impact of an identified item for an individual segment may be less than $100 million when the item impacts several segments or several periods. The most directly comparable financial measure that is disclosed in the financial statements is "Net income (loss)" within the company’s Consolidated statement of income. Management uses these figures to improve comparability of the underlying business across multiple periods by isolating and removing significant non-operational events from business results. The company believes this view provides investors increased transparency into business results and trends, and provides investors with a view of the business as seen through the eyes of management. Net income (loss) excluding identified items is not meant to be viewed in isolation or as a substitute for net income (loss) as prepared in accordance with U.S. GAAP. All identified items are presented on an after-tax basis.
