In this report, all dollar amounts are expressed in Canadian dollars unless otherwise stated. This report should be read in conjunction with the company’s annual report on Form 10-K for the year ended December 31, 2024. Note that numbers may not add due to rounding.

The term “project” as used in this report can refer to a variety of different activities and does not necessarily have the same meaning as in any government payment transparency reports.

In this report, unless the context otherwise indicates, reference to “the company” or “Imperial” includes Imperial Oil Limited and its subsidiaries.

These unaudited consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (GAAP) and follow the same accounting policies and methods of computation as, and should be read in conjunction with, the most recent annual consolidated financial statements filed with the U.S. Securities and Exchange Commission (SEC) in the company’s 2024 annual report on Form 10-K. In the opinion of the company, the information furnished herein reflects all known accruals and adjustments necessary for a fair statement of the results for the periods reported herein. All such adjustments are of a normal recurring nature.

The company’s exploration and production activities are accounted for under the “successful efforts” method.

Amounts for related party revenues and purchases for the three months ended September 30, 2024 have been revised from $2,999 million to $3,755 million and from $1,199 million to $1,955 million, respectively. Amounts for related party revenues and purchases for the nine months ended September 30, 2024 have been revised from $8,674 million to $10,829 million and from $3,022 million to $5,177 million, respectively. Impacts of the revision offset to zero.

The results for the nine months ended September 30, 2025, are not necessarily indicative of the operations to be expected for the full year.

All amounts are in Canadian dollars unless otherwise indicated.

(a)Includes export sales to the United States of $2,404 million (2024 - $2,631 million).

(b)Revenues include both revenue within the scope of ASC 606 and outside the scope of ASC 606. Trade receivables in "Accounts receivable - net" reported on the Consolidated balance sheet include both receivables within the scope of ASC 606 and outside the scope of ASC 606. Revenue and receivables outside the scope of ASC 606 primarily relate to physically settled commodity contracts accounted for as derivatives. Contractual terms, credit quality and type of customer are generally similar between contracts within the scope of ASC 606 and those outside it.    

(c)Capital and exploration expenditures (CAPEX) include exploration expenses, additions to property, plant and equipment, additions to finance leases, additional investments and acquisitions and the company’s share of similar costs for equity companies. CAPEX excludes the purchase of carbon emission credits.

(d)In 2025, in conjunction with the company signing an agreement to sell the Calgary Imperial campus, the Upstream segment transferred the asset to the Corporate and other segment for $466 million. The effects of this transaction have been eliminated for consolidation purposes. Prior periods have not been recast.

Investment and other income included gains and losses on asset sales as follows:

The components of net benefit cost were as follows:

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.

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:

Realized and unrealized gain/(loss) on derivative instruments recognized in the Consolidated statement of income is included in the following line on a before-tax basis:

The estimated fair value of derivative instruments, and the related hierarchy level for the fair value measurement, were as follows:

At September 30, 2025 and December 31, 2024, the company had $12 million and $22 million, respectively, of collateral under a master netting arrangement not offset against the derivatives on the Consolidated balance sheet in “Accounts receivable - net”, primarily related to initial margin requirements.

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:

The following table provides the calculation of basic and diluted earnings per common share and the dividends declared by the company on its outstanding common shares:

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.

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.

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.

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

Margins - Higher margins primarily reflect improved market conditions.

Other - Includes lower turnaround impacts of about $70 million.

Higher refinery throughput was primarily due to lower turnaround impacts.

Lower petroleum product sales were primarily due to lower volumes in the supply and wholesale channels.

(a)Share repurchases were made under the company’s normal course issuer bid program, and include shares purchased from Exxon Mobil Corporation.

Current year results include identified items1 of a $306 million after-tax ($406 million before-tax) non-cash impairment charge and a $249 million after-tax ($330 million before-tax) restructuring charge.

Price – Average bitumen realizations decreased by $5.92 per barrel, primarily driven by lower marker prices partially offset by narrowing WTI/WCS spread. Synthetic crude oil realizations decreased by $10.51 per barrel, primarily driven by lower WTI partially offset by an improved Synthetic/WTI spread.

Volume – Higher volumes were driven by higher production at Syncrude, Kearl and Cold Lake.

Other – Primarily due to favourable foreign exchange impacts of about $200 million.

(a)In 2025, Syncrude gross production included about 2 thousand barrels per day of bitumen and other products (2024 - 1 thousand barrels per day) that were exported to the operator's facilities using an existing interconnect pipeline.

Margins – Higher margins primarily reflect improved market conditions.

Other – Primarily due to unfavourable wholesale volume impacts of about $70 million, higher operating expenses of about $70 million driven by higher energy costs, and unplanned downtime of about $60 million, partially offset by lower turnaround impacts of about $100 million.

Margins - Lower margins primarily reflect weaker industry polyethylene margins.

Current year results include identified items1 of a $306 million after-tax ($406 million before-tax) non-cash impairment charge and a $249 million after-tax ($330 million before-tax) restructuring charge; results also reflect higher incentive compensation as a result of the higher share price.

Cash flows used in investing activities primarily reflect lower additions to property, plant and equipment.

On June 23, 2025, the company announced by news release that it had received final approval from the Toronto Stock Exchange for a new normal course issuer bid and will continue its existing share purchase program. The program enables the company to purchase up to a maximum of 25,452,248 common shares during the period June 29, 2025 to June 28, 2026. This maximum 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. The program will end should the company purchase the maximum allowable number of shares or otherwise on June 28, 2026. 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.

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 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.

As indicated in the certifications in Exhibit 31 of this report, the company’s principal executive officer and principal financial officer have evaluated the company’s disclosure controls and procedures as of September 30, 2025. Based on that evaluation, these officers have concluded that the company’s disclosure controls and procedures are effective in ensuring that information required to be disclosed by the company in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to them in a manner that allows for timely decisions regarding required disclosures and are effective in ensuring that such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. There has not been any change in the company’s internal control over financial reporting during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the company’s internal control over financial reporting.

Imperial has elected to use a $1 million (U.S. dollars) threshold for disclosing environmental proceedings.
