DISCLOSURES ABOUT OIL AND GAS PRODUCING ACTIVITIES TOPIC 932 “EXTRACTIVE ACTIVITIES – OIL AND GAS” (unaudited)

The following select disclosures of Cenovus Energy Inc.’s (“Cenovus” or the “Company”) reserves and other oil and gas information have been prepared in accordance with United States (“U.S.”) Financial Accounting Standards Board (“FASB”) Topic 932, “Extractive Activities – Oil and Gas” and the U.S. disclosure requirements of the Securities and Exchange Commission (“SEC”).

All amounts pertaining to Cenovus’s audited Consolidated Financial Statements are prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (the “IFRS Accounting Standards”). Unless otherwise noted, all dollars are in millions of Canadian dollars. All references to C$ or $ are to Canadian dollars and references to US$ are to U.S. dollars.

RESERVES DATA

The SEC Modernization of Oil and Gas Reporting final rules require that proved after royalty reserves be estimated using existing economic conditions (constant pricing). Cenovus’s results have been calculated using the average of the first-day-of-the-month prices for the prior twelve-month period. This same twelve-month average price is also used in calculating the aggregate amount of (and changes in) future cash inflows related to the standardized measure of discounted future net cash flows relating to proved oil and gas reserves (“SMOG”). Future fluctuations in prices, production rates, or changes in political or regulatory environments could cause Cenovus’s share of future production from its reserves to be materially different from that presented.

The reserves disclosed are effective December 31, 2024, and were prepared by the independent, qualified reserves evaluators (“IQREs”) McDaniel & Associates Consultants Ltd. and GLJ Ltd. There are significant differences between reserves evaluated under the SEC requirements and those presented in the Company’s Annual Information Form filed under National Instrument 51-101 “Standards of Disclosure for Oil and Gas Activities” (“NI 51-101”). NI 51-101 requires disclosure of before royalties reserves and the associated values using forecasted prices and costs.

The reserves presented in this supplemental information are estimates only. There are numerous uncertainties inherent in estimating quantities of reserves, including many factors beyond the Company’s control. In general, estimates of economically recoverable bitumen, crude oil, natural gas liquids and natural gas reserves and the future net cash flows derived therefrom are based upon a number of variable factors and assumptions, including but not limited to: product prices; future operating and capital costs; historical production from the properties and the assumed effects of regulation by governmental agencies, including with respect to environmental regulations, royalty payments and taxes; initial production rates; production decline rates; and the availability, proximity and capacity of oil and gas gathering systems, pipelines and processing facilities, all of which may vary considerably from actual results.

All such estimates are to some degree uncertain and classifications of reserves are only attempts to define the degree of uncertainty involved. For those reasons, estimates of the economically recoverable bitumen, crude oil, natural gas liquids and natural gas reserves attributable to any particular group of properties, classification of such reserves based on risk of recovery and estimates of future net revenues expected therefrom, prepared by different engineers or by the same engineers at different times, may vary substantially. Cenovus’s actual production, sales, royalty payments, taxes and development and operating expenditures with respect to its reserves may vary from current estimates and such variances may be material. Actual reserves may be greater than or less than the estimates disclosed. For a full discussion of Cenovus’s material risk factors refer to “Risk Management and Risk Factors” in the Company’s annual 2024 Management’s Discussion and Analysis included in the annual report on Form 40-F of which this document forms a part.

Estimates with respect to reserves that may be developed and produced in the future are often based upon volumetric calculations and upon analogy to similar types of reserves, rather than upon actual production history. Subsequent evaluation of the same reserves based upon production history will result in variations, which may be material, in the estimated reserves. Canadian provincial royalties are determined based on a graduated percentage scale which varies with prices and production rates. Canadian reserves, as presented on a net basis, assume royalty rates in existence at the time the estimates were made.

The reserves data contained herein is dated February 18, 2025, with an effective date of December 31, 2024.

(1)Definitions:

(a) “Net” reserves are the remaining reserves attributable to Cenovus, after deduction of estimated royalties and including royalty interests.

(b) “Proved” oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating methods and government regulations, i.e., prices and costs as of the date the estimate is made.

(c) “Developed” oil and gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods in which the cost of the required equipment is relatively minor compared to the cost of a new well.

(d) “Undeveloped” reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(2)Estimates of total net proved bitumen, crude oil, natural gas liquids, or natural gas reserves are not filed by Cenovus with any U.S. federal authority or agency other than the SEC.

(3)“Million barrels” is abbreviated as MMbbls, “billion cubic feet” is abbreviated as Bcf, and “million barrels of oil equivalent” is abbreviated as MMBOE.

Changes to Reserves

The explanation of significant year-over-year changes in the Company’s net proved reserves for the years ended December 31, 2024, and December 31, 2023, is set forth below.

Year ended December 31, 2024

The changes to the Company's net proved bitumen reserves in 2024 are explained as follows:

•Technical revisions and improved recovery: Decreases to recovery factors at Christina Lake and Foster Creek and changes to the Lloydminster thermal development plan resulted in a decrease in net proved reserves of 157 million barrels. Increased forecast capital and operating costs reduced royalties payable for the Oil Sands segment, which resulted in an increase in net proved reserves of 90 million barrels.

•Revisions due to price: Increased bitumen prices increased royalties payable for the Oil Sands segment, which resulted in a decrease in net proved reserves.

•Extensions and discoveries: Continuing development and development plan updates at Christina Lake, Foster Creek and Lloydminster thermal increased net proved reserves.

The changes to the Company's net proved reserves of crude oil, natural gas liquids and natural gas in 2024 are explained as follows:

•Technical revisions and improved recovery: Increases to original natural gas in place volumes for China and Indonesia were partially offset by updates to the Conventional segment development plans, increasing net proved reserves.

•Revisions due to price: Lower product pricing for the Conventional segment, China and Indonesia decreased net proved reserves.

•Extensions and discoveries: Continuing development of the West White Rose project and development within the Conventional segment and Lloydminster conventional heavy oil increased net proved reserves.

•Purchase of reserves in place: The acquisition of an equity interest in Duvernay Energy Corporation increased net proved reserves.

•Sale of reserves in place: The sale of minor interests within the Conventional segment decreased net proved reserves.

Cenovus Energy Inc. 6 Supplementary Information – Oil and Gas Activities (unaudited)

Year ended December 31, 2023

The changes to the Company's net proved bitumen reserves in 2023 are explained as follows:

•Technical revisions and improved recovery: Decreases to recovery factors at Christina Lake and Foster Creek, offset by improved recovery performance at Lloydminster thermal resulted in a decrease in net proved reserves of 83 million barrels. Increased forecast capital and operating costs reduced royalties payable for the Oil Sands segment, which resulted in an increase in net proved reserves of 50 million barrels.

•Revisions due to price: Lower bitumen prices reduced royalties payable for the Oil Sands segment, which resulted in an increase in net proved reserves.

•Extensions and discoveries: Regulatory approvals at Foster Creek and Lloydminster thermal increased net proved reserves.

•Purchase of reserves in place: An acquisition in the Oil Sands segment increased net proved reserves.

The changes to the Company's net proved reserves of crude oil, natural gas liquids and natural gas in 2023 are explained as follows:

•Technical revisions and improved recovery: Updates to the Conventional segment development plans were partially offset by improved recovery performance in the Offshore segment, decreasing net proved reserves.

•Revisions due to price: Lower product pricing within the Conventional segment and Lloydminster conventional heavy oil decreased net proved reserves.

•Extensions and discoveries: Development within the Conventional segment increased net proved reserves.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS AND CHANGES THEREIN

In calculating SMOG, the average of the first-day-of-the-month prices for the prior twelve-month period and cost assumptions were applied to Cenovus’s annual future production from net proved reserves to determine cash inflows. Future production and development costs do not include any cost inflation and assume the continuation of existing economic, operating and regulatory conditions. Future income taxes are calculated by applying statutory income tax rates to future pre-tax cash flows after provision for the tax cost of the oil and natural gas properties based upon existing laws and regulations. The discount was computed by application of a 10 percent discount factor to the future net cash flows. The calculation of SMOG is based upon the discounted future net cash flows prepared by IQREs in relation to the reserves they respectively evaluated, and adjusted to the extent provided by contractual arrangements such as price risk management activities, in existence at year end and to account for asset retirement obligations and future income taxes.

Cenovus cautions that the discounted future net cash flows relating to proved oil and gas reserves are an indication of neither the fair market value of Cenovus’s oil and gas properties, nor the future net cash flows expected to be generated from such properties. The discounted future net cash flows do not include the fair market value of exploratory properties and probable or possible oil and gas reserves, nor is consideration given to the effect of anticipated future changes in crude oil, natural gas liquids and natural gas prices, development, asset retirement and production costs and possible changes to tax and royalty regulations. The prescribed discount rate of 10 percent may not appropriately reflect future interest rates. The computation also excludes values contributed by Cenovus’s enhancement of the netback price from market optimization activities.

Computation of the SMOG was based on the following average of the first-day-of-the-month benchmark prices for the twelve-month period before the end of the year. Natural gas prices for China and Indonesia reserves are based on various gas sales agreements in place.

(1)On January 1, 2019, Cenovus adopted IFRS 16, “Leases” (“IFRS 16”), which prescribes a different accounting treatment for operating leases than U.S. Generally Accepted Accounting Principles (“US GAAP”). Under US GAAP, the amortization of a right-of-use asset and interest expense related to an operating lease are recorded by nature of the expense on the income statement (production costs). Under IFRS 16, amortization of a right-of-use asset and interest expense are classified as depreciation expense and finance costs, respectively. As a result, changes in SMOG due to the amortization of right-of-use assets and interest payments have been included by Cenovus in “Net change in prices and production costs”.
