Total revenue increased to $691.8 million in 2025 compared to $494.4 million in 2024, an increase of $197.4 million or 40%.

Revenue from concentrate from the Mount Polley mine in 2025 was $387.0 million compared to $301.5 million in 2024, an

increase of $85.5 million. In 2025, the Mount Polley mine had 6.3 concentrate shipments (2024-7.0 concentrate shipments).

Imperial’s 30% share of revenue from the Red Chris mine in 2025 was $304.2 million compared to $190.0 million in 2024, an

increase of $114.2 million. In 2025, the Red Chris mine (100% basis) had 20.0 concentrate shipments (2024-19 concentrate

shipments).

Variations in revenue are impacted by the restart of operations, the timing and quantity of concentrate shipments, metal

prices and exchange rates, and period end revaluations of revenue attributed to concentrate shipments where copper and

gold prices will settle at a future date.

The London Metals Exchange cash settlement copper price per pound averaged US$ 4.51 in 2025 compared to US$4.15 in

2024. London Bullion Market Association, London gold price per troy ounce averaged US$ 3,435 in 202 5 compared to

US$2,387 in 2024. The average US/CDN dollar exchange rate in 202 5 was 1.398 compared to an average of 1.370 in 2024.

In CDN dollar terms, the average copper price in 2025 was CDN$6.30 per pound compared to CDN$5.68 per pound in 2024,

and the average gold price in 2025 was CDN$4,802 per ounce compared to CDN$3,271 per ounce in 2024.

The total revenue includes a positive r evenue revaluation in 2025 of $ 34.3 million compared to a negative revenue

revaluation of $11.1 million in 2024. Revenue revaluations are the result of the metal price on the settlement date and/or

the current period balance sheet date being higher or lower than when the revenue was initially recorded or the metal price

at the last balance sheet date and finalization of contained metal as a result of final assays and weights.

Net income in 2025 was $153.8 million ($0.91 per share) compared to a net income of $106.3 million ($0.66 per share) in

2024. The majority of the increase in net income of $47.5 million was primarily due to the following factors:

• Income from mine operations increased to $304.3 million in 2025 from income of $161.2 million in 2024, an increase of

$143.1 million;

• interest expense, net of interest income and capitalized interest was $25.6 million in 2025 compared to $34.7 million in

2024, a decrease of $9.1 million due to the reduction in debt; and

• tax expense of $95.9 million in 2025 increased from a tax expense of $5.3 million in 2024, an increase of $90.6 million.

Capital expenditures including finance leases were $ 243.3 million in 2025, up from $202.2 million in 2024. Expenditures in

2025 included:

• $77.4 million in exploration and development, an increase of $9.9 million in comparison to $67.5 million in 2024;

• $60.4 million for tailings dam construction, an increase of $7.4 million in comparison to $53.0 million in 2024;

• $69.0 million on stripping costs, an increase of $28.0 million in comparison to $41.0 million in 2024; and

• Investment in sustaining capital of $36.5 million, a decrease of $4.2 million in comparison $40.7 million in 2024.

At December 31, 2025, the Company had $36.8 million in cash and cash equivalents, compared to $58.1 million at December

31, 2024.

At December 31, 2025, the Company had not hedged any copper, gold or US/CDN Dollar exchange. Revenues will fluctuate

depending on copper and gold prices, the US/CDN Dollar exchange rate, and the timing of concentrate sales, which is

dependent on concentrate production and the availability and scheduling of transportation .

OPERATIONS

Mount Polley Mine

During the year ended December 31, 2025, a total of 6.714 million tonnes of ore was treated. Metal production was 30.715

million pounds of copper and 37,555 ounces of gold , a decrease of 14% and 4% respectively from 35.700 million pounds

copper and 39,108 ounces gold produced in 202 4. Copper recovery averaged 81.4% and gold recovery was 68.5% from

grades averaging 0.255% copper and 0.254 g/t gold.

During the fourth quarter of 2025 1.452 million tonnes of ore were treated, down 12.6% in comparison to the fourth quarter

of 202 4. The production during the fourth quarter of 202 5 was 4.660 million pounds copper, down 49.6 % from the

comparative quarter of 2024 and 6,589 ounces gold, down 31.1% from the comparative quarter of 2024.

imperialmetals.com

The majority of the mill feed during the fourth quarter was from Phase 5 and low grade stockpiles. This led to lower grades

and lower copper recovery during the period. The Phase 4 and 5 pushbacks of the Springer Pit generated approximately

50% of the mill feed during the quarter with the remainder coming from lower grade stockpiles. Phase 4 mining will be

completed in March 2026.

The 2026 production target for the Mount Polley mine is 19.0 – 21.0 million pounds copper and 40,000-44,000 ounces gold.

The majority of the mill feed in 2026 will come from the Phase 5 pushback in the Springer Pit which will be supplemented

with low grade stockpiles to supply the mill feed.

Exploration program

Mount Polley 2025 Phase 2 exploration program had three goals: (i) to test a high-grade zone beneath the Wight Pit, (ii) to

expand and determine the boundaries for mineralization in a potential C2 open pit expansion and find the boundaries of

the higher gold grade encountered at depth in the C2 zone, and (iii) to test beneath the previously mined Bell Pit for depth

extension.

The next phase of diamond drilling started in February 2026 and follows up on the successful results from the first drilling

campaign at the Mount Polley mine in more than a decade in the Bell Pit area.

Exploration, development, and capital expenditures in 202 5 were $131.8 million compared to $ 96.5 million in the 202 4

comparative year.

Red Chris Mine

Red Chris metal production (100% basis) for 2025 was 93.101 million pounds copper and 92,429 ounces gold, an increase of

9% and 55% respectively from the 85.321 million pounds copper and 59,811 ounces gold produced in 2024. The increase of

metal production in 2025 was due to higher grades and higher gold recovery , partially offset by lower tonnes of ore milled.

Imperial’s 30% share of Red Chris mine production for 202 5 was 27.930 million pounds of copper up from 25.596 million

pounds copper in 2024 and 27,729 ounces of gold up from 17,943 ounces gold in 2024.

Gold - ounces 26,482 24,359 92,429 59,811

Newmont Mining Corporation’s guidance for Red Chris mine production (100%) is 60.0 – 66.0 million pounds of copper and

47,500 – 52,500 ounces of gold for the calendar year 2026. Both copper and gold production are expected to be lower in

2026 at Red Chris as the mining sequence provides for mining lower grade ore and stockpile processing durin g the year

while stripping for the next open pit mining phase.

Imperial’s 30% share of exploration, development, and capital expenditures in 2025 were $107.0 million compared to

$104.0 million in the 2024 comparative year.

Block Cave Feasibility Study

The Red Chris feasibility study for a block cave expansion operation is advancing, as are permitting activities to support th e

underground project. Completion of the feasibility study and, subject to the study outcomes, joint venture approval are

expected in the second half of 2026.

Exploration Program

Exploration plans for 2026 include drilling at the Far West zone and the Main Zone Offset zone, an interpreted zone of

mineralization truncated and offset by the South Boundary fault. There will be surface exploration programs outside of the

known zones of mineralization and the continuing of re-logging of the GJ property historic diamond drill core.

Huckleberry Mine

Huckleberry operations ceased in August 2016 and the mine remains on care and maintenance status.

Site personnel continue to focus on maintaining site access, water management, maintenance of site infrastructure and

equipment, and mine permit compliance. Work is also planned in 2026 to investigate and update the tailings facility design

for Huckleberry.

Diamond drilling at Huckleberry in 2025 consisted of nine drillholes, totalling 1,743 metres, intersect ing copper,

molybdenum, silver, and gold mineralization. The program tested an underexplored area southwest of the Main Zone pit.

Angled diamond drill holes were designed to intersect the southern contact between the Main Zone intrusive stock and the

surrounding host volcanic rock. Historically, the bulk of ore mined from t he Main Zone occurred near this contact in the

volcanic rock east and northeast of t he Main Zone stock. The 2025 drilling expands upon and infills the Main Zone mineral

resource to the southwest. Additional drilling is planned for 2026 to infill and expand upon the mineralization in this area .

In 2025, Huckleberry incurred idle mine costs comprised of $ 7.9 million in operating costs and $ 1.3 million in depreciation

expense, which is a decrease from $8.1 million in operating costs and $1.2 million in depreciation in 2024.

Exploration, development, and capital expenditures were $3.4 million in 2025 compared to $0.8 million in 2024.

TECHNICAL INFORMATION

The technical and scientific information related to the Company’s mineral projects has been reviewed and approved by

Steve Robertson, P.Geo., Imperial’s Vice President Corporate Development, and a designated Qualified Person as defined

by NI 43-101.

NON-GAAP FINANCIAL MEASURES

The Company reports on four non-GAAP financial measures: adjusted net income, adjusted EBITDA, cash earnings and cash

cost per pound of copper produced, which are described in detail below. The Company believes these measures are useful

to investors because they are included in the measures that are used by management in assessing the financial performance

of the Company.

Adjusted net income, adjusted EBITDA, cash earnings and cash cost per pound of copper are not standardized financial

measures under IFRS Accounting Standards and might not be comparable to similar financial measures disclosed by other

issuers.

Adjusted Net Income and Adjusted Net Income Per Share

Adjusted net income is derived from operating net income by removing the gains or loss , resulting from acquisition and

disposal of property , net of tax, unrealized foreign exchange gains or losses on long term debt, net of tax and other non -

recurring items. Adjusted net income in 2025 was $153.9 million ($0.91 per share) compared to an adjusted net income of

$102.8 million ($0.64 per share) in 2024. We believe that the presentation of Adjusted Net Income helps investors better

understand the results of our normal operating activities and the ongoing cash generating potential of our business .

Adjusted EBITDA

Adjusted EBITDA in 2025 was $381.7 million compared to $207.8 million in 2024. We define Adjusted EBITDA as net income

before interest expense, net of interest income and capitalized interest, taxes, depletion, and depreciation, and as adjusted

for certain other items.

imperialmetals.com

Cash Earnings and Cash Earnings Per Share

Cash earnings in 2025 was $374.5 million compared to $209.0 million in 2024. Cash earnings per share were $2.23 in 2025

compared to $1.29 in 2024.

Cash earnings and cash earnings per share are measures used by the Company to evaluate its performance ; however, they

are not terms recognized under IFRS Accounting Standards . We believe that the presentation of cash earnings and cash

earnings per share is appropriate to provide additional information to investors about how well the Company can earn cash

to pay its debts and manage its operating expenses and investment. Cash earnings is defined as cash flow from operations

before the net change in non-cash working capital balances, income and mining taxes paid, and interest paid. Cash earnings

per share is the same measure divided by the weighted average number of common shares outstanding during the year.

Cash Cost Per Pound of Copper Produced

Management uses this non-GAAP financial measure to monitor operating costs and profitability. The Company is primarily

a copper producer and therefore calculates this non-GAAP financial measure individually for its two operating copper mines,

Mount Polley and Red Chris (30% share), and on a composite basis for these mines.

Variations from period to period in the cash cost per pound of copper produced are the result of many factors including:

grade, metal recoveries, amount of stripping charged to operations, mine and mill operating conditions, labour and other

cost inputs, transportation and warehousing costs, treatment and refining costs, the amount of by -product and other

revenues, the US$ to CDN$ exchange rate and the amount of copper produced .

FOURTH QUARTER RESULTS FROM OPERATIONS

Revenue in the fourth quarter of 2025 was $ 170.7 million compared to $132.0 million in 2024. Sales revenue is recorded

when title for concentrate is transferred on ship loading. Variations in revenue are impacted by the timing and quantity of

concentrate shipments, metal prices and exchange rates, and period end revaluations of revenue attributed to concentrate

shipments where copper and gold prices will settle at a future date along with finalization of contained metals as a result

of final assays.

The income from mine operations in the fourth quarter of 2025 was $72.6 million compared to the income of $63.4 million

in the comparative quarter of 2024.

imperialmetals.com

The Company recorded a net income of $33.4 million ($0.19 income per share) in the fourth quarter of 2025 compared to

net income of $62.8 million ($0.39 income per share) in the prior year quarter. The difference is mainly due to the current

and deferred income and mining tax expense of $25.0 million in the fourth quarter of 2025 compared to the net tax

recovery of $10.2 million in the prior year quarter of 2024.

Expenditures for exploration and ongoing capital projects at Mount Polley, Red Chris and Huckleberry totalled $63.1 million

during the fourth quarter of 2025, compared to $45.6 million in the 2024 comparative quarter.

OUTLOOK

Corporate and Operations

The 2026 production target for Mount Polley is 19.0 – 21.0 million pounds copper and 40,000 – 44,000 ounces of gold.

Newmont guidance for Red Chris mine production (100%) is 60.0 – 66.0 million pounds copper and 47,500 – 52,500 ounces

of gold for the calendar year 2026.

The Company may need to conclude further financing arrangements to fund its share of cost of the ongoing development

of a block cave mine at Red Chris.

Exploration

Imperial maintains a large portfolio of greenfield exploration properties in British Columbia. These properties have defined

areas of mineralization and exploration potential. Management continues to evaluate various opportunities to advance

many of these properties.

A diamond drilling program is scheduled in 2026 for Mount Polley to follow up on the successful drilling completed in 2025.

Diamond drilling will be completed in 2026 at the Huckleberry mine to expand and infill the Main zone.

Acquisitions

Management continues to evaluate potential acquisitions.
