Teck Reports Unaudited First Quarter Results for2025


Strong quarterly EBITDA and resilient balancesheet


Vancouver, B.C. – Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (Teck) today announced its unaudited first quarter results for 2025.

"Our profitability improved significantly in the first quarter compared to a year ago as a result of higher commodity prices and copper sales volumes, and we continue to return significant cash to shareholders," said Jonathan Price, President and CEO. "We remain committed to our strategy of balancing value-accretive growth with returns to shareholders, and our strong balance sheet and commercial strategy provide us with resilience and the ability to continue to create value amidst market uncertainty."

Highlights

· Adjusted EBITDA^1^ of $927 million in Q1 2025 more<br>than doubled compared to the same period last year, primarily driven by higher copper and zinc prices, and increased sales volumes of<br>copper and zinc in concentrate. Our profit from continuing operations before taxes was $450 million in Q1 2025.
· Adjusted profit from continuing operations attributable to<br>shareholders^1^ was $303 million, or $0.60 per share, in Q1 2025. Our profit from continuing operations attributable to shareholders<br>was $370 million.
--- ---
· From January 1 through April 23, 2025, we returned $505 million<br>to shareholders through share buybacks, and in total, have completed $1.75 billion of our authorized share buyback program of $3.25 billion.
--- ---
· Our strong balance sheet provides resilience to market uncertainty,<br>with liquidity as at April 23, 2025 of $10.0 billion, including $5.8 billion of cash. We ended the quarter in a net cash^1^<br>position of $764 million.
--- ---
· QB successfully achieved the completion testing requirements<br>under the US$2.5 billion project finance facility, another milestone for QB that further confirms the robustness of the design, construction<br>and operational performance of the asset as we advance ramp-up to consistent full production.
--- ---
· Copper production increased by 7% to 106,100 tonnes in Q1<br>2025 with steady performance across our established operations. QB produced 42,300 tonnes as production was impacted by an extended shutdown<br>in January, a national power outage in Chile, and challenging weather, which reduced material movement needed to complete planned tailings<br>lifts, ultimately reducing asset utilization.
--- ---
· Our copper business generated gross profit before depreciation<br>and amortization^1^ of $704 million in the first quarter, up 90% from a year ago, driven by higher copper prices and an increase<br>in sales volumes of 11% to 106,200 tonnes. Gross profit from our copper business was $343 million in the first quarter.
--- ---
· Our zinc business generated gross profit before depreciation<br>and amortization^1^ of $225 million in the first quarter, up 79% from a year ago, supported by a 16% increase in zinc prices,<br>strong sales volumes at Red Dog, and improved profitability at Trail. Sales volumes from Red Dog were 90,800 tonnes, higher than our previously<br>disclosed guidance range. Gross profit from our zinc business was $193 million in the first quarter.
--- ---
· QB's third labour union ratified a new three-year collective<br>bargaining agreement in early April, completing all labour negotiations for QB's workforce. Labour agreements are now in place through<br>2028 across our QB operation.

Key Updates


QB Ramp-Up


· QB ramp-up continued in the quarter with production of 42,300<br>tonnes. Production during the quarter was impacted by the 18-day shutdown in January to conduct maintenance and reliability work, and<br>complete additional tailings lifts as part of the development of the Tailings Management Facility (TMF), as previously disclosed. Production<br>was also negatively impacted by a nationwide power outage in Chile at the end of February, which resulted in the site being without power<br>causing several days of unplanned downtime.
· In the first quarter, challenging weather impacted the material<br>movement needed to complete the planned tailings lifts, ultimately reducing asset utilization and production. TMF development was also<br>impacted by challenges with sand deposition in the first quarter of 2025 due to sand drainage times being longer than expected. This has<br>resulted in a delay in completing the required tailings lifts associated with the development of the TMF. As a result, we expect to extend<br>planned maintenance shutdowns in the second and third quarters to advance TMF development.
--- ---
· Despite factors impacting asset utilization at QB, outlined<br>above, and excluding the extended shut-down in the quarter, the average daily plant throughput increased in the first quarter of 2025<br>compared to the fourth quarter of 2024, demonstrating continued improvement in operational stability. Higher levels of transition ore<br>material were mined in the first quarter, leading to lower recoveries, consistent with our previously disclosed guidance. Higher grade<br>ore mined in March increased the average grade in the first quarter. We continue to estimate average grades of approximately 0.60% for<br>2025, and grade variability is expected over the mine life.
--- ---

· The overall performance of QB continues to improve, as indicated<br>by the average daily throughput rates, and recoveries and grades are in line with our expectations. Further validating the capability<br>of the operations to operate at design levels and generate strong cash flow, we achieved the QB project financing completion testing requirements,<br>which included a series of independently verified operational and technical tests. With this milestone now reached, Teck and the other<br>sponsor guarantees of the project finance facility have been released.
| 2 |

| --- | | · | We continue to expect to be within our previously disclosed<br>2025 annual copper and molybdenum production guidance ranges for QB of between 230,000 and 270,000 tonnes and between 3,000 and 4,500<br>tonnes, respectively, albeit at the lower end of the ranges as a result of the maintenance shutdowns, noted above. Our previously disclosed<br>2025 annual net cash unit cost^1^ guidance for QB of US$1.80 –$2.15 per pound is unchanged, although we expect to be at<br>the higher end of the range. | | --- | --- |


Note:

1. This is a non-GAAP financial measure or ratio. See “Use of Non-GAAP Financial Measures and Ratios” for further information.

Value-Driven Growth


· In Q1, we continued to make progress in advancing our copper<br>growth strategy, reinforcing our commitment to long-term value creation through a balanced approach of growth investments and shareholder<br>returns. Our focus remains on advancing our near-term projects – Highland Valley Copper Mine Life Extension (HVC MLE), Zafranal,<br>where we received the permit for Advanced Works in early April, and San Nicolás - for potential sanction decisions in 2025, and<br>advancing optimization of QB, with a strong focus on identifying near-term opportunities for debottlenecking within the current asset<br>base.
· Our disciplined capital allocation framework and project<br>sanction requirements address short term uncertainty in commodity pricing and enable prudent deployment of capital. All growth projects<br>must meet stringent criteria, delivering attractive risk-adjusted returns and competing for capital in alignment with Teck’s capital<br>allocation framework.
--- ---

Safety and Sustainability Leadership


· Our High-Potential Incident (HPI) Frequency rate remained<br>low at 0.05, reflecting strong safety performance in the first quarter of 2025.
· On March 21, 2025, we released our 24th annual Sustainability<br>Report, outlining Teck’s 2024 environmental and social performance and continued commitment to responsible development.

USE OF NON-GAAP FINANCIAL MEASURES ANDRATIOS

Our annual financial statements are prepared in accordance with IFRS^®^ Accounting Standards as issued by the International Accounting Standards Board (IASB). Our interim financial results are prepared in accordance with IAS 34, Interim Financial Reporting (IAS 34). This document refers to a number of non-GAAP financial measures and non-GAAP ratios, which are not measures recognized under IFRS Accounting Standards and do not have a standardized meaning prescribed by IFRS Accounting Standards or by Generally Accepted Accounting Principles (GAAP) in the United States.

The non-GAAP financial measures and non-GAAP ratios described below do not have standardized meanings under IFRS Accounting Standards, may differ from those used by other issuers, and may not be comparable to similar financial measures and ratios reported by other issuers. These financial measures and ratios have been derived from our financial statements and applied on a consistent basis as appropriate. We disclose these financial measures and ratios because we believe they assist readers in understanding the results of our operations and financial position and provide further information about our financial results to investors. These measures should not be considered in isolation or used as a substitute for other measures of performance prepared in accordance with IFRS Accounting Standards.

Adjusted profit (loss) from continuing operationsattributable to shareholders – For adjusted profit from continuing operations attributable to shareholders, we adjust profit from continuing operations attributable to shareholders as reported to remove the after-tax effect of certain types of transactions that reflect measurement changes on our balance sheet or are not indicative of our normal operating activities.

EBITDA – EBITDA is profit before net finance expense, provision for income taxes, and depreciation and amortization.

Adjusted EBITDA – Adjusted EBITDA is EBITDA before the pre-tax effect of the adjustments that we make to adjusted profit from continuing operations attributable to shareholders as described above.

Adjusted profit from continuing operations attributable to shareholders, EBITDA and Adjusted EBITDA highlight items and allow us and readers to analyze the rest of our results more clearly. We believe that disclosing these measures assists readers in understanding the ongoing cash-generating potential of our business in order to provide liquidity to fund working capital needs, service outstanding debt, fund future capital expenditures and investment opportunities, and pay dividends.


Adjusted basic earnings (loss) per sharefrom continuing operations – Adjusted basic earnings per share from continuing operations is adjusted profit from continuing operations attributable to shareholders divided by average number of shares outstanding in the period.

Adjusted diluted earnings (loss) per sharefrom continuing operations – Adjusted diluted earnings per share from continuing operations is adjusted profit from continuing operations attributable to shareholders divided by average number of fully diluted shares in a period.


Gross profit before depreciation and amortization – Gross profit before depreciation and amortization is gross profit with depreciation and amortization expense added back. We believe this measure assists us and readers to assess our ability to generate cash flow from our reportable segments or overall operations.

Total cash unit costs – Total cash unit costs for our copper and zinc operations includes adjusted cash costs of sales, as described below, plus the smelter and refining charges added back in determining adjusted revenue. This presentation allows a comparison of total cash unit costs, including smelter charges, to the underlying price of copper or zinc in order to assess the margin for the mine on a per unit basis.

Net cash unit costs – Net cash unit costs of principal product, after deducting co-product and by-product margins, are also a common industry measure. By deducting the co- and by-product margin per unit of the principal product, the margin for the mine on a per unit basis may be presented in a single metric for comparison to other operations.

| 5 |

| --- |

Adjusted cash cost of sales – Adjusted cash cost of sales for our copper and zinc operations is defined as the cost of the product delivered to the port of shipment, excluding depreciation and amortization charges, any one-time collective agreement charges or inventory write-down provisions and by-product cost of sales. It is common practice in the industry to exclude depreciation and amortization, as these costs are non-cash, and discounted cash flow valuation models used in the industry substitute expectations of future capital spending for these amounts.

Total debt – Total debt is the sum of debt plus lease liabilities, including the current portions of debt and lease liabilities.

Net debt (cash) – Net debt (cash) is total debt, less cash and cash equivalents. Net cash is the amount by which our cash balance exceeds our total debt balance.

Statements regarding the availability of our credit facilities are based on assumptions that we will be able to satisfy the conditions for borrowing at the time of a borrowing request and that the facilities are not otherwise terminated or accelerated due to an event of default. Assumptions regarding the costs and benefits of our projects include assumptions that the relevant project is constructed, commissioned and operated in accordance with current expectations. Expectations regarding our operations are based on numerous assumptions regarding the operations. Our Guidance tables include disclosure and footnotes with further assumptions relating to our guidance, and assumptions for certain other forward-looking statements accompany those statements within the document. Statements concerning future production costs or volumes are based on numerous assumptions regarding operating matters and on assumptions that demand for products develops as anticipated, that customers and other counterparties perform their contractual obligations, that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, interruption in transportation or utilities, or adverse weather conditions, and that there are no material unanticipated variations in the cost of energy or supplies. The foregoing list of assumptions is not exhaustive. Events or circumstances could cause actual results to vary materially.

Factors that may cause actual results to vary materially include, but are not limited to, changes in commodity and power prices; changes in market demand for our products; changes in interest and currency exchange rates; acts of governments and the outcome of legal proceedings; the imposition of tariffs, import or export restrictions, or other trade barriers or retaliatory measures by foreign or domestic governments; inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral reserves and resources); operational difficulties (including failure of plant, equipment or processes to operate in accordance with specifications or expectations, cost escalation, unavailability of labour, materials and equipment); government action or delays in the receipt of government approvals; changes in royalty or tax rates; industrial disturbances or other job action; adverse weather conditions; unanticipated events related to health, safety and environmental matters; union labour disputes; political risk; social unrest; failure of customers or counterparties (including logistics suppliers) to perform their contractual obligations; changes in our credit ratings; unanticipated increases in costs to construct our development projects; difficulty in obtaining permits; inability to address concerns regarding permits or environmental impact assessments; and changes or further deterioration in general economic conditions. The amount and timing of capital expenditures is depending upon, among other matters, being able to secure permits, equipment, supplies, materials and labour on a timely basis and at expected costs. Certain operations and projects are not controlled by us; schedules and costs may be adjusted by our partners, and timing of spending and operation of the operation or project is not in our control. Certain of our other operations and projects are operated through joint arrangements where we may not have control over all decisions, which may cause outcomes to differ from current expectations. Ongoing monitoring may reveal unexpected environmental conditions at our operations and projects that could require additional remedial measures. Production at our QB and Red Dog Operations may also be impacted by water levels at site. Sales to China may be impacted by general and specific port restrictions, Chinese regulation and policies, and normal production and operating risks.

We assume no obligation to update forward-looking statements except as required under securities laws. Further information concerning risks, assumptions and uncertainties associated with these forward-looking statements and our business can be found in our Annual Information Form for the year ended December 31, 2024 filed under our profile on SEDAR+ (www.sedarplus.ca) and on EDGAR (www.sec.gov) under cover of Form 40-F, as well as subsequent filings that can also be found under our profile.

Teck Reports Unaudited First Quarter Results for2025

Strong quarterly EBITDA and resilient balancesheet


Vancouver, B.C. – Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (Teck) today announced its unaudited first quarter results for 2025.

"Our profitability improved significantly in the first quarter compared to a year ago as a result of higher commodity prices and copper sales volumes, and we continue to return significant cash to shareholders," said Jonathan Price, President and CEO. "We remain committed to our strategy of balancing value-accretive growth with returns to shareholders, and our strong balance sheet and commercial strategy provide us with resilience and the ability to continue to create value amidst market uncertainty."


Highlights

Adjusted EBITDA^1^ of $927 million in Q1 2025 more<br>than doubled compared to the same period last year, primarily driven by higher copper and zinc prices, and increased sales volumes of<br>copper and zinc in concentrate. Our profit from continuing operations before taxes was $450 million in Q1 2025.
Adjusted profit from continuing operations attributable to<br>shareholders^1^ was $303 million, or $0.60 per share, in Q1 2025. Our profit from continuing operations attributable to shareholders<br>was $370 million.
--- ---
From January 1 through April 23, 2025, we returned $505 million<br>to shareholders through share buybacks, and in total, have completed $1.75 billion of our authorized share buyback program of $3.25 billion.
--- ---
Our strong balance sheet provides resilience to market uncertainty,<br>with liquidity as at April 23, 2025 of $10.0 billion, including $5.8 billion of cash. We ended the quarter in a net cash^1^<br>position of $764 million.
--- ---
QB successfully achieved the completion testing requirements<br>under the US$2.5 billion project finance facility, another milestone for QB that further confirms the robustness of the design, construction<br>and operational performance of the asset as we advance ramp-up to consistent full production.

Copper production increased by 7% to 106,100 tonnes in Q1<br>2025 with steady performance across our established operations. QB produced 42,300 tonnes as production was impacted by an extended shutdown<br>in January, a national power outage in Chile, and challenging weather, which reduced material movement needed to complete planned tailings<br>lifts, ultimately reducing asset utilization.
--- ---
Our copper business generated gross profit before depreciation<br>and amortization^1^ of $704 million in the first quarter, up 90% from a year ago, driven by higher copper prices and an increase<br>in sales volumes of 11% to 106,200 tonnes. Gross profit from our copper business was $343 million in the first quarter.
--- ---
Our zinc business generated gross profit before depreciation<br>and amortization^1^of $225 million in the first quarter, up 79% from a year ago, supported by a 16% increase in zinc prices,<br>strong sales volumes at Red Dog, and improved profitability at Trail. Sales volumes from Red Dog were 90,800 tonnes, higher than our previously<br>disclosed guidance range. Gross profit from our zinc business was $193 million in the first quarter.

Key Updates


QB Ramp-Up


QB ramp-up continued in the quarter with production of 42,300<br>tonnes. Production during the quarter was impacted by the 18-day shutdown in January to conduct maintenance and reliability work, and<br>complete additional tailings lifts as part of the development of the Tailings Management Facility (TMF), as previously disclosed. Production<br>was also negatively impacted by a nationwide power outage in Chile at the end of February, which resulted in the site being without power<br>causing several days of unplanned downtime.
In the first quarter, challenging weather impacted the material<br>movement needed to complete the planned tailings lifts, ultimately reducing asset utilization and production. TMF development was also<br>impacted by challenges with sand deposition in the first quarter of 2025 due to sand drainage times being longer than expected. This has<br>resulted in a delay in completing the required tailings lifts associated with the development of the TMF. As a result, we expect to extend<br>planned maintenance shutdowns in the second and third quarters to advance TMF development.
--- ---
Despite factors impacting asset utilization at QB, outlined<br>above, and excluding the extended shut-down in the quarter, the average daily plant throughput increased in the first quarter of 2025<br>compared to the fourth quarter of 2024, demonstrating continued improvement in operational stability. Higher levels of transition ore<br>material were mined in the first quarter, leading to lower recoveries, consistent with our previously disclosed guidance. Higher grade<br>ore mined in March increased the average grade in the first quarter. We continue to estimate average grades of approximately 0.60% for<br>2025, and grade variability is expected over the mine life.
--- ---
The overall performance of QB continues to improve, as indicated<br>by the average daily throughput rates, and recoveries and grades are in line with our expectations. Further validating the capability<br>of the operations to operate at design levels and generate strong cash flow, we achieved the QB project financing completion testing requirements,<br>which included a series of independently verified operational and technical tests. With this milestone now reached, Teck and the other<br>sponsor guarantees of the project finance facility have been released.

| --- | --- | | • | We continue to expect to be within our previously disclosed<br>2025 annual copper and molybdenum production guidance ranges for QB of between 230,000 and 270,000 tonnes and between 3,000 and 4,500<br>tonnes, respectively, albeit at the lower end of the ranges as a result of the maintenance shutdowns, noted above. Our previously disclosed<br>2025 annual net cash unit cost^1^ guidance for QB of US$1.80 – $2.15 per pound is unchanged, although we expect to be at<br>the higher end of the range. | | --- | --- |

Value-Driven Growth

In Q1, we continued to make progress in advancing our copper<br>growth strategy, reinforcing our commitment to long-term value creation through a balanced approach of growth investments and shareholder<br>returns. Our focus remains on advancing our near-term projects – Highland Valley Copper Mine Life Extension (HVC MLE), Zafranal,<br>where we received the permit for Advanced Works in early April, and San Nicolás - for potential sanction decisions in 2025, and<br>advancing optimization of QB, with a strong focus on identifying near-term opportunities for debottlenecking within the current asset<br>base.
Our disciplined capital allocation framework and project<br>sanction requirements address short term uncertainty in commodity pricing and enable prudent deployment of capital. All growth projects<br>must meet stringent criteria, delivering attractive risk-adjusted returns and competing for capital in alignment with Teck’s capital<br>allocation framework.

Management's Discussion and Analysis

This management's discussion and analysis (MD&A) is dated as atApril 23, 2025 and should be read in conjunction with the unaudited condensed interim consolidated financial statements of Teck ResourcesLimited (Teck) and the notes thereto for the three months ended March 31, 2025 and with the audited consolidated financial statementsof Teck and the notes thereto for the year ended December 31, 2024. In this news release, unless the context otherwise dictates, a referenceto “the company” or “us,” “we” or “our” refers to Teck and its subsidiaries. Additionalinformation, including our Annual Information Form and Management’s Discussion and Analysis for the year ended December 31, 2024,is available on SEDAR+ at www.sedarplus.ca.

This document contains forward-looking statements and forward-lookinginformation. Please refer to the cautionary language under the heading “CAUTIONARY STATEMENT ON FORWARD-LOOKING STATEMENTS”below.

Overview

Our strong balance sheet provides resilience to market uncertainty<br>with liquidity as at April 23, 2025 of $10.0 billion, including $5.8 billion of cash. We ended the quarter in a net cash^1^<br>position of $764 million.
Our profitability improved significantly in the first quarter<br>compared to the same period a year ago primarily as a result of higher base metal prices, increased copper and zinc in concentrate sales<br>volumes, and the positive impact of a weaker Canadian dollar on our business. In addition, as a result of rising copper prices in the<br>first quarter, we recorded positive pricing adjustments of $106 million. Our profit from continuing operations attributable to shareholders<br>was $370 million in the first quarter compared with a $125 million loss from continuing operations attributable to shareholders in the<br>first quarter of 2024.
--- ---
In the first quarter, London Metal Exchange (LME) copper<br>prices increased by 11% compared to a year ago, averaging US$4.24 per pound, and LME zinc prices increased by 16%, averaging US$1.29 per<br>pound. The average CAD$/US$ exchange rate weakened to $1.44 in the first quarter compared with $1.35 in the same period last year, which<br>had a positive impact on our financial results.
--- ---
Average Prices and Exchange Rates Three months ended <br> March 31, Change
--- --- --- --- --- --- --- ---
2025 2024
Copper (LME cash – US$/pound) $ 4.24 $ 3.83 11 %
Zinc (LME cash – US$/pound) $ 1.29 $ 1.11 16 %
Average exchange rate (CAD$ per US$1.00) $ 1.44 $ 1.35 7 %
In addition to the favourable price environment for our principal<br>products, our financial results also benefited from increased revenues from other by-products that we produce. This includes molybdenum,<br>driven by higher production from QB and Highland Valley Copper, as well as silver, germanium and other critical metals from our Trail<br>Operations.
--- ---
Copper sales volumes of 106,200 tonnes in the first quarter<br>increased by 11% compared with a year ago reflecting higher volumes from Highland Valley Copper and Carmen de Andacollo. Zinc in concentrate<br>sales volumes of 108,400 tonnes in the first quarter increased by 10% compared with a year ago due to timing of sales from Red Dog and<br>increased volumes from Antamina. Red Dog's zinc in concentrate sales were 90,800 tonnes in the first quarter, higher than our previously<br>disclosed guidance range of 75,000 to 90,000 tonnes.

| --- | --- | | • | Copper production was 106,100 tonnes in the first quarter,<br>an increase of 7,100 tonnes compared with the same period a year ago with stable performance across our established operations. Production<br>at Carmen de Andacollo and Highland Valley Copper was higher than the same period last year. | | --- | --- | | • | QB produced 42,300 tonnes of copper as production was impacted<br>by an extended shutdown in January, a national power outage in Chile, and challenging weather, which reduced material movement needed<br>to complete planned tailings lifts, ultimately reducing asset utilization. Further details are outlined in the Copper section below. | | --- | --- | | • | Zinc in concentrate production in the first quarter was 137,300<br>tonnes, a decrease of 14% compared to a year ago as a result of lower production from Red Dog, partly offset by higher zinc production<br>from Antamina. The reduced production from Red Dog was a result of lower ore grades and recoveries, as expected in the mine plan. | | --- | --- | | • | Our finance income increased to $91 million in the first<br>quarter compared with $27 million a year ago reflecting investment income on our elevated cash balance as a result of the receipt of proceeds<br>from the sale of the steelmaking coal business in 2024. | | --- | --- | | • | We continued to return cash to shareholders through share<br>buybacks and dividends that totaled $443 million in the first quarter. From January 1 through April 23, 2025, we returned $505 million<br>to shareholders through share buybacks, and in total, have completed $1.75 billion of our authorized share buyback program of $3.25 billion. | | --- | --- | | • | The potential imposition of tariffs and countervailing restrictions<br>between the United States and other countries is a fluid and rapidly evolving situation that is being closely monitored by Teck. We sell<br>refined zinc and lead, and specialty metals such as germanium, indium, and sulphur products from Canada into the United States from our<br>Trail Operations in B.C. These products are compliant with the United States-Mexico-Canada trade agreement (USMCA). We typically sell<br>a portion of our Red Dog zinc and lead concentrate to customers in China. The 2025 Red Dog shipping season is not yet underway and we<br>are working actively with our global customers and will continue to manage our sales arrangements to minimize the impact to Red Dog and<br>the rest of our business from possible tariffs. | | --- | --- | | • | We paid a final 2024 Canadian income tax instalment of $630<br>million in the first quarter of 2025, as previously disclosed, primarily relating to earnings and proceeds from the sale of the steelmaking<br>coal business in 2024. | | --- | --- | | • | As a result of the completion of the sale of our steelmaking<br>coal business in the third quarter of 2024, results from that business have been presented in our Q1 2025 News Release and Condensed Interim<br>Consolidated Financial Statements as discontinued operations for all periods reported. | | --- | --- |

Profit (Loss) from Continuing Operations Attributableto Shareholders and Adjusted Profit (Loss) from Continuing Operations Attributable to Shareholders

In the first quarter, our profit from continuing operations attributable to shareholders was $370 million, or $0.74 per share, compared to a loss of $125 million, or $0.24 per share, in the same period last year. The increase compared with a year ago is primarily due to higher copper and zinc prices, and increased copper and zinc in concentrate sales volumes. In addition, our profit in the first quarter also benefited from increased revenues from the various by-products we produce including molybdenum, silver and germanium, and from a weaker Canadian dollar as compared to a year ago.

Adjusted profit from continuing operations attributable to shareholders^1^ in the first quarter, taking into account the items identified in the table below, was $303 million, or $0.60 per share, compared with a $6 million loss, or $0.01 per share, in the first quarter of 2024. The most significant after-tax adjustment to profit in the first quarter of 2025, reflected in the table below, is $50 million relating to changes to the carrying value of the financial liability for the preferential dividend stream to Corporación Nacional del Cobre de Chile (Codelco).

Performance

Gross profit from our copper segment increased to $343 million in the first quarter compared with $106 million a year ago (see table below) primarily due to higher copper prices and sales volumes, and higher by-product and co-product revenues from molybdenum and zinc. These items were partly offset by increased depreciation of QB assets as depreciation of additional QB assets began in the second quarter of 2024, and higher depreciation of capitalized stripping at Highland Valley Copper.

Copper production was 106,100 tonnes in the first quarter, an increase of 7% from the same period last year, driven by increased grades and mill throughput at Carmen de Andacollo and Highland Valley Copper. QB produced 42,300 tonnes of copper in the first quarter compared with 43,300 tonnes in the first quarter last year and 60,700 tonnes in the fourth quarter of 2024. A number of factors impacted asset utilization at QB in the quarter, as outlined below.

The table below summarizes the change in gross profit in our copper segment for the quarter.

Property, plant and equipment expenditures in the first quarter totalled $277 million, including $185 million for sustaining capital. Sustaining capital expenditures included $138 million at QB primarily associated with ongoing construction of the Tailings Management Facility, as noted below, as well as ongoing construction of the truck shop.

Capitalized production stripping costs were $47 million in the first quarter compared with $82 million a year ago.

Markets

In the first quarter, LME copper prices rose 2% over the previous quarter to average US$4.24 per pound and were up 11% over the same period last year. Despite growing economic fears, global demand for copper remained robust, supported by government and corporate spending on renewable energy and infrastructure construction. Copper prices along with most commodity prices, came under pressure in early April on concerns over the impact of import tariffs on the US economy and its global trading partners. We expect Chinese consumers to continue to step-up purchases opportunistically at prices below US$4.00 per pound.

The tightness in the copper concentrate market continued to increase during the first quarter. Spot treatment charges fell to record lows, continuing a decline that started in the third quarter last year. Global copper concentrate production grew by 3.2% in 2024 to 19.3 million tonnes, while smelter capacity grew 4.4% last year to 22.8 million tonnes. Over the past 5 years, growth in smelter capacity has outpaced mine production growth by 2.1 times with 4.7 million tonnes of smelter capacity added for 2.2 million tonnes of increased concentrate production. Expectations for 2025 mine production have fallen by over 1.0 million tonnes from this time last year. Meanwhile, new smelter capacity continues to come online into 2025, with both new smelters and expansion of existing smelters expected in 2025 and 2026. With no clear pathway to solve the excess in global smelting capacity, in our view treatment and refining charges have reset to a lower range than seen previously, with an even greater share of revenue accruing to miners.

Global stocks of copper cathode on exchanges at the end of the first quarter were approximately 6.6 days of global consumption compared to the long-term average of 10.3 days, with more than half of the stocks currently in China and close to 80% of visible stocks in Asian warehouses. Total visible stocks, including bonded stocks, rose by 150,000 tonnes in the seasonally weak first quarter, though many stocks currently residing in the US may end up unavailable to the market should the US Section 232 investigation into copper result in a high import tariff level.

Operations

Quebrada Blanca

The following are the key updates relating to operational performance at QB in the first quarter:

QB ramp-up continued in the quarter with production of 42,300<br>tonnes. Production during the quarter was impacted by the 18-day shutdown in January to conduct maintenance and reliability work, and<br>complete additional tailings lifts as part of the development of the Tailings Management Facility (TMF), as previously disclosed. Production<br>was also negatively impacted by a nationwide power outage in Chile at the end of February which resulted in the site being without power<br>causing several days of unplanned downtime.
In the first quarter, challenging weather impacted the material<br>movement needed to complete the planned tailings lifts, ultimately reducing asset utilization and production. TMF development was also<br>impacted by challenges with sand deposition in the first quarter of 2025 due to sand drainage times being longer than expected. This has<br>resulted in a delay in completing the required tailings lifts associated with the development of the TMF. As a result, we expect to extend<br>planned maintenance shutdowns in the second and third quarters to advance TMF development.

Highland Valley Copper

Copper production of 29,500 tonnes in the first quarter was 4,100 tonnes higher than a year ago primarily due to higher ore grades and higher mill throughput, as we advance mining in the Lornex pit. Copper sales volumes of 30,500 tonnes in the first quarter were 4,000 tonnes higher than a year ago, reflecting the higher production levels.

Copper production in the first quarter increased from the fourth quarter of 2024 due to improved processing rates and higher grades, as expected in the mine plan. Quarterly copper production is expected to increase as more Lornex ore is released throughout 2025, as previously disclosed, and our 2025 annual production guidance for HVC of 135,000 to 150,000 tonnes is unchanged.

Operating costs in the first quarter of $201 million, before changes in inventory, were $5 million higher than a year ago, driven primarily by higher mill throughput.

There were no capitalized production stripping costs in the first quarter compared with $34 million in the same period last year, reflecting completion of waste stripping in the Lornex pit.

Antamina

Copper production (100% basis) of 95,000 tonnes in the first quarter was 9,100 tonnes lower than a year ago primarily due to lower mill throughput, as expected in the mine plan. The mix of mill feed in the quarter was 62% copper-only ore and 38% copper-zinc ore, compared with 67% copper-only ore and 33% copper-zinc ore a year ago. Zinc production (100% basis) was 91,300 tonnes in the first quarter compared with 64,700 tonnes a year ago due to higher grades and recoveries, as expected in the mine plan.

Operating costs in the first quarter, before changes in inventory, of US$90 million (22.5% share) were consistent with a year ago.


Carmen de Andacollo

Copper production of 13,000 tonnes in the first quarter increased by 6,100 tonnes, or by 88%, compared to the same period last year. The increase was driven by higher grades, recoveries and mill throughput. Improved mill throughput was the result of increased water availability compared to the same period last year, which was affected by drought conditions.

Operating costs in the first quarter of US$55 million, before changes in inventory, were consistent with operating costs in the same period a year ago as increased consumption of supplies was offset by reduced maintenance costs.

Cost of Sales

Cost of sales was $1.2 billion in the first quarter compared with $1.0 billion in the same period last year. The increase is primarily due to increased depreciation expense, higher sales volumes, and the impact of translation of our U.S. dollar denominated cost of sales at a weaker Canadian dollar exchange rate, compared with a year ago. We recorded $361 million of depreciation and amortization expense in the first quarter compared with $265 million in the same period last year. The increase was primarily the result of commencement of depreciation of additional QB assets in the second quarter of 2024, and higher depreciation of capitalized stripping at Highland Valley Copper.

Excluding QB, total cash unit costs^1^ in the first quarter were US$2.15 per pound compared to US$2.25 per pound in the first quarter of 2024 and US$2.18 per pound in the fourth quarter of 2024, primarily due to lower smelter processing charges and increased copper production volumes from Carmen de Andacollo and Highland Valley Copper. Including QB, total cash unit costs^1^ in the first quarter were US$2.48 per pound compared with US$2.58 per pound in the same period last year. Although total cash unit costs^1^ were lower than a year ago, additional maintenance costs and lower production, both at QB, in the first quarter of 2025 led to higher than expected total cash unit costs^1^. Despite this, we are expecting to be within our total cash unit costs^1^ guidance for 2025.

Excluding QB, net cash unit costs^1^ in the first quarter were US$1.64 per pound, or US$0.28 per pound lower than a year ago primarily the result of higher by-product zinc revenue credits from Antamina and increased molybdenum revenue credits from Highland Valley Copper. Including QB, net cash unit costs^1^ for the first quarter were US$2.04 per pound, US$0.32 per pound lower than the same period a year ago, as a result of increased by-product credits, reduced smelter processing charges, and lower transportation costs at QB.

Outlook

Our 2025 annual guidance for our copper segment is outlined in our guidance tables on pages 26–29 and is unchanged from our previously issued guidance.

We continue to expect to be within our previously disclosed 2025 annual copper and molybdenum production guidance ranges for QB of between 230,000 and 270,000 tonnes and 3,000 and 4,500 tonnes, respectively, albeit at the lower end of the ranges as a result of the maintenance shutdowns, noted above. Our previously disclosed 2025 annual net cash unit cost^1^ guidance for QB of US$1.80-$2.15 per pound is unchanged, although we expect to be at the higher end of the range.


Copper Growth

We are focused on advancing our near-term copper growth projects, which are progressing as planned. We are driving progress by completing feasibility studies, advancing detailed engineering, preparing for the execution of advanced work programs, and moving forward with permitting—particularly at HVC MLE, Zafranal, and San Nicolás. We are also defining the most capital-efficient and value-accretive path for the expansion of QB, informed by the performance of our existing assets and permitting needs. Additionally, we remain committed to advancing our medium- and long-term portfolio options with targeted investments.


Our capital allocation framework and thorough project sanction requirements address short term uncertainty in commodity pricing and enable prudent deployment of capital. All growth projects must meet stringent criteria, delivering attractive risk-adjusted returns and competing for capital in alignment with Teck’s capital allocation framework.

Our 2025 Copper Growth capital guidance is unchanged. The HVC MLE and Zafranal projects are currently focused on advancing detailed engineering, design, and project execution planning, which are critical steps in meeting our investment requirements for full project sanctioning. For Zafranal, in addition to engineering and planning activities, we will proceed with advanced early works in 2025 to enable construction to start following project sanction.

Our remaining copper growth capital expenditures are expected to be deployed to continue to progress our copper growth pipeline of medium- to long-term projects including Galore Creek, Schaft Creek, New Range, and NuevaUnion. These investments reflect our commitment to disciplined capital allocation, positioning us to advance these growth initiatives efficiently and in alignment with our long-term copper strategy.

ZINC SEGMENT


Three months ended <br> March 31,
(CAD$ in millions) 2025 2024
Zinc price (realized – US$/pound) $ 1.28 $ 1.12
Production (000’s tonnes)
Refined zinc 58 63

Gross profit $ 193 $ 63
Gross profit before depreciation and amortization^2^ $ 225 $ 126
Property, plant and equipment expenditures $ 51 $ 33

Performance

Gross profit from our zinc segment increased to $193 million in the first quarter from $63 million a year ago (see table below) due to higher zinc prices, lower zinc treatment charges, and higher by-product revenues. Gross profit before depreciation and amortization^2^ at Trail significantly improved in the first quarter to $80 million from $25 million in same period a year ago due to the implementation of initiatives to improve profitability and cash flows, as well as the weakening of the Canadian dollar, and higher by-product production such as germanium and indium.

Zinc production at Red Dog in the first quarter decreased by 20% from a year ago to 116,800 tonnes, while lead production remained consistent at 25,000 tonnes. Zinc production decreased as a result of lower grades and recoveries, as expected in the mine plan. Zinc sales volumes from Red Dog of 90,800 tonnes in the first quarter were 7% higher than the same period a year ago and higher than our previously disclosed guidance range of 75,000 to 90,000 tonnes.

Trail Operations refined zinc production in the first quarter was 58,300 tonnes, 5,200 tonnes lower than a year ago, aligned with our previously disclosed operating plan to maximize profitability in challenging smelter market conditions.

The table below summarizes the change in gross profit in our zinc segment for the quarter.

Gross Profit (CAD$ in millions) Three months ended <br> March 31,
As reported in the first quarter of 2024 $ 63
Increase (decrease):
Zinc price realized 37
Smelter processing charges (mining operations) 12
Unit operating costs 7
Co-product and by-product contribution 56
Royalties (37 )
Foreign exchange 24
Depreciation 31
Net increase $ 130
As reported in current quarter $ 193

Property, plant and equipment expenditures in the first quarter totalled $51 million, including $21 million for sustaining capital, of which $5 million relates to our Trail Operations and $16 million relates to our Red Dog Operations.

Markets

Prices for zinc on the LME in the first quarter averaged US$1.29 per pound, a decrease of 7% over the previous quarter, but up 16% over the same period last year. While global steel markets remain weak, the refined zinc market in North America continued to improve in the first quarter, as domestic steel production increased in line with higher domestic steel prices following the increase in US import tariffs. We estimate that total reported global stocks, which include LME, SHFE and bonded stocks, fell by approximately 45,000 tonnes in the first quarter to less than 225,000 tonnes, representing an estimated 6.0 days of global demand, compared to the 25-year average of 18.7 days. This is an extremely low level, and leaves the market sensitive to any supply interruptions. However, with pressure on global steel trade, we do expect zinc demand to trend flat to down year over year in the second quarter.

Global zinc concentrate production fell in 2024 for the third straight year. The zinc concentrate market remained tight with spot treatment charges remaining well below historical averages. Imports of concentrates into China fell 13% in 2024, but rose 33% in the first two months of 2025. While Wood Mackenzie is forecasting an increase in mine production in 2025, the increase in smelter capacity is more than double the size of the mine increase. The lack of available raw materials continues to constrain metal production, which fell year over year in 2024. Zinc metal consumption rose in 2024 by 1.7% and was projected to grow at 2.1% in 2025 at the start of the year. We expect every available tonne of concentrate to be processed by smelters, with projected concentrate deficits likely to translate into less refined metal output. Typically this would feed into a refined metal deficit, but the pressures in global auto markets following US tariffs are also seeing demand expectations for 2025 lowered at the present time.

Operations

Red Dog

Zinc production decreased to 116,800 tonnes in the first quarter compared with 145,300 tonnes a year ago as a result of lower grades and recoveries as expected in the mine plan. Lead production of 25,000 tonnes in the first quarter was similar to a year ago.

Zinc sales volumes of 90,800 tonnes in the first quarter were 7% higher than the same period a year ago and higher than our previously disclosed guidance range of 75,000 to 90,000 tonnes. The higher sales volumes were primarily due to the timing of shipments.

Operating costs, before changes in inventory and royalties, in the first quarter were US$109 million, or US$5 million lower than a year ago due to reduced contractor and diesel costs.

Trail Operations

Refined zinc production of 58,300 tonnes in the first quarter was 5,200 tonnes lower than a year ago, in line with an updated operating plan to maximize profitability in challenging smelter market conditions. Refined lead production was 23,000 tonnes in the first quarter, 6,500 tonnes higher than a year ago as a result of the KIVCET boiler operating at higher throughput and online time after its replacement in 2024.

In the fourth quarter of 2024 and first quarter of 2025, we continued to focus on implementing initiatives to improve the profitability and cash flow generation of Trail. The benefit of these initiatives, combined with a weaker Canadian dollar and increased production of by-products such as silver, germanium and indium contributed to an increase in profitability in the first quarter compared to the same quarter a year ago.

Operating costs, before changes in inventory, in the first quarter were $13 million lower than a year ago at $136 million, primarily due to reduction of contractor costs and the timing of maintenance.

| 17 | Teck Resources Limited 2025 First Quarter News Release |

| --- | --- |

Cost of Sales

Cost of sales was $587 million in the first quarter compared to $478 million a year ago. The increase in cost of sales was due to higher concentrate purchase costs at Trail as a result of lower treatment charges, higher NANA royalties at Red Dog as a result of increased profitability, and the impact of translating our U.S. dollar denominated cost of sales at a weaker Canadian dollar exchange rate, compared with a year ago. These items were partly offset by lower depreciation expense in the first quarter of 2025 due to the impairment of Trail assets in the third quarter of 2024, as previously disclosed.

Total cash unit costs^1^ for Red Dog were US$0.61 per pound in the first quarter, a decrease of US$0.07 per pound compared to the same period last year primarily due to reduced smelter processing charges, partly offset by the impact of lower production levels that were anticipated in the mine plan. Net cash unit costs^1^ of US$0.59 per pound in the first quarter were US$0.08 per pound lower than a year ago for the same reasons described above for the decrease in total cash unit costs^1^. Our previously disclosed 2025 annual guidance for zinc net cash unit costs^1^ of US$0.45–$0.55 per pound is unchanged and our first quarter 2025 net cash unit costs^1^ reflect the normal seasonality of sales at Red Dog.

Three months ended <br> March 31,
(amounts reported in US$ per pound) 2025 2024
Adjusted cash cost of sales^1^ $ 0.45 $ 0.41
Smelter processing charges 0.16 0.27
Total cash unit costs^1^ $ 0.61 $ 0.68
Cash margin for by-products^1^ (0.02 ) (0.01 )
Net cash unit costs^1^ $ 0.59 $ 0.67

Outlook

Our 2025 annual guidance for our zinc segment is outlined in our guidance tables on pages 26–29 and is unchanged from our previously issued guidance.

We expect sales of zinc in concentrate at Red Dog to be in the range of 25,000 to 35,000 tonnes in the second quarter of 2025, reflecting the normal seasonality of Red Dog sales.

OTHER OPERATING INCOME AND EXPENSES


Other operating income, net of other expense, was $73 million in the first quarter compared with a $69 million expense a year ago. The year-over-year change in the first quarter of 2025 was primarily due to significantly higher positive settlement pricing adjustments and lower share-based compensation expense. The most significant item in the first quarter of 2025 was $106 million of positive settlement pricing adjustments.

The table below outlines our outstanding receivable positions, which are valued using provisional prices at December 31, 2024 and March 31, 2025.

Outstanding at Outstanding at
March 31, 2025 December 31, 2024
(payable pounds in millions) Pounds US/lb. Pounds US/lb.
Copper 247 178
Zinc 63 141

All values are in US Dollars.

Our general and administration costs were $75 million in the first quarter, compared to $62 million a year ago, and our research and innovation costs were $10 million, compared to $18 million a year ago. In total, our corporate costs are consistent with the same period last year and we continue to expect a reduction in our annual 2025 general and administration and research and innovation costs. This excludes investment in the implementation of a new enterprise resource planning (ERP) system across the company, which we expect to commence in 2025. We expect most costs associated with the ERP implementation will be expensed and in the first quarter, we expensed $3 million, which is included in our general and administration costs.

In the first quarter, our finance income was $91 million compared to $27 million a year ago. The increase in finance income is attributed to the interest earned on our higher cash balance in the first quarter as a result of the proceeds received from the sale of the steelmaking coal business in the third quarter of 2024.

Finance expense includes the interest on our debt, QB project financing, advances from Sumitomo Metal Mining Co., Ltd. and Sumitomo Corporation (SMM/SC), and lease liabilities, as well as letters of credit and standby fees, the interest components of our pension obligations, and the accretion on our decommissioning and restoration provisions, less any interest that we capitalize against our development projects. Our finance expense decreased to $220 million in the first quarter compared to $223 million a year ago, despite lower capitalized borrowing costs in the first quarter of 2025. Debt interest expense decreased to $26 million from $55 million a year ago due to the purchase of our public term notes and repayment of our short-term loans at Carmen de Andacollo. Interest expense on the QB project finance facility decreased to $40 million from $55 million in the same period a year ago, as we continue to reduce the QB project finance facility through scheduled semi-annual repayments.

Non-operating income, net of non-operating expense, was $76 million in the first quarter compared with $38 million expense in the same period last year. The most significant item in the quarter was a $84 million gain on the changes to the carrying value of the financial liability for the preferential dividend stream to Codelco. The carrying value of this financial liability is most significantly affected by copper prices and the interest rate on the subordinated loans provided by Teck and SMM/SC to Compania Minera Teck Quebrada Blanca SA (QBSA), which affects when QBSA repays the loans.

Income Taxes


Provision for income and resource taxes from continuing operations was $137 million, or 30% of pre-tax profit. This quarter, our effective tax rate was influenced by several factors, including the adjustment in the carrying value of the Codelco preferential dividend liability, a one-time tax recovery of previously unrecognized tax benefits, and other items. Excluding these factors, our rate would have been approximately 41%, which is higher than the Canadian statutory income tax rate of 27%, primarily due to resource taxes and foreign withholding taxes.

We are subject to and pay income and resource taxes in all jurisdictions that we operate in. A final 2024 Canadian income tax instalment of $630 million, primarily related to earnings and proceeds from the sale of the steelmaking coal business, was paid in February, as previously disclosed.

Going forward, we expect our average long-term effective tax rate to be in the range of 39% to 41%, but quarterly and annual results may vary due to the relative amount of operating margins, the scope and timing of other copper growth projects, certain corporate and finance expenses that are not deductible for resource tax purposes, and statutory tax rates in the jurisdictions in which we operate, and other factors.


FINANCIAL POSITION AND LIQUIDITY


Our strong balance sheet provides resilience to market uncertainty. As at March 31, 2025, our financial position and liquidity remained very strong. Our debt position, net debt (cash)^2^ and credit ratios are summarized in the table below.

Our liquidity was $10.0 billion as at April 23, 2025, including $5.8 billion of cash. Our cash balance decreased by $1.4 billion in the first quarter compared to December 31, 2024 as we continued to deploy the proceeds from the sale of the steelmaking coal business to cash returns to shareholders, cash tax payments associated with the earnings and transaction-related taxes of the steelmaking coal business, and the advancement of our near-term copper growth projects.

| 20 | Teck Resources Limited 2025 First Quarter News Release |

We returned $443 million to shareholders in the first quarter through the purchase of $380 million of Class B subordinate voting shares pursuant to our normal course issuer bid, and $63 million in dividends reflecting our regular base quarterly dividend. As at April 23, 2025, we have completed $1.75 billion of our authorized $3.25 billion share buyback program.

Teck maintains a limited recourse QB project financing facility with a remaining balance of US$1.9 billion at March 31, 2025. Prior to achievement of completion testing, the project was guaranteed on a several basis by Teck and SMM/SC pro rata to the respective equity interests in the Series A shares of QBSA. In March 2025, we achieved the QB project financing completion testing requirements, which included a series of independently verified operational and technical tests, validating the capability of the operations to operate at design levels and generate strong cash flow. With this milestone now reached, Teck and the other sponsor guarantees of the project finance facility have been released.

We maintain various committed and uncommitted credit facilities for liquidity and for the issuance of letters of credit. Our US$3.0 billion committed revolving credit facility is a sustainability linked-facility, which involves pricing adjustments that are aligned with our sustainability performance and strategy. Our sustainability performance over the term of the facility is measured by greenhouse gas (GHG) intensity, percentage of women in Teck's workforce, and safety. This facility does not contain an earnings- or cash flow-based financial covenant, a credit rating trigger or a general material adverse effect borrowing condition. The only financial covenant under our bank agreements is a requirement for our adjusted net debt to capitalization ratio not to exceed 60%. That ratio was negative at March 31, 2025.

Antamina maintains a US$1.0 billion loan agreement that matures in July 2026. Our 22.5% share of the loan is US$225 million. The loan is non-recourse to us and to the other Antamina owners.

We also have various other uncommitted credit facilities, standby letters of credit and surety bonds that primarily secure our reclamation obligations. The amounts issued under these facilities totaled $2.1 billion at March 31, 2025. We may be required to post additional security in respect of reclamation at our remaining sites in future periods as additional land is disturbed, regulatory requirements change or closure plans are updated.

Operating Cash Flow


Our operating cash flows from continuing operations improved significantly in the first quarter compared to the same period last year, reflecting higher copper and zinc prices, higher sales volumes, and significantly lower tax payments. Our operating cash flows from continuing operations in the first quarter included a final 2024 Canadian income tax instalment of $630 million, primarily related to earnings and proceeds from the sale of the steelmaking coal business, as noted above. Excluding this cash payment, we generated operating cash flows of $115 million in the first quarter. Our first quarter 2024 operating cash flows included tax payments of $1.3 billion that related to 2023 earnings and taxes on 2022 earnings.

During the first quarter, changes in working capital items resulted in a use of cash of $607 million primarily due to a significant reduction in accounts payable. This compares with a $290 million use of cash in the first quarter of 2024. Typically, in the first quarter of each year we have a use of cash through our working capital by way of reduction of accounts payables and other liabilities due to the payment of the seasonally larger fourth quarter NANA royalty at Red Dog, as well as other various annual expenses which are paid in the first quarter.

Investing Activities


Expenditures on property, plant and equipment were $332 million in the first quarter, including $206 million of sustaining capital and $122 million on growth, primarily relating to our near-term copper growth projects. The largest components of sustaining capital expenditures in the first quarter were $138 million at QB, as noted above, and $23 million at Antamina.

Capitalized production stripping costs decreased to $61 million in the first quarter compared with $104 million a year ago, with the reduction reflecting the completion of waste stripping in the Lornex pit at Highland Valley Copper, as previously disclosed.

Financing Activities


In the first quarter, we purchased US$15 million of our public notes through open market repurchases.

Interest and finance fees paid in the first quarter totalled $55 million, which was $42 million lower than a year ago, due to the reduction in our term notes following our tender offer in the third quarter of 2024.

FINANCIAL RISK MANAGEMENT

Sales of our products are denominated in U.S. dollars while a large portion of our expenses and capital expenditures are incurred in local currencies, particularly the Canadian dollar and the Chilean peso. Foreign exchange fluctuations can have a significant effect on our operating margins, unless such fluctuations are offset by related changes to commodity prices.

Our U.S. dollar denominated debt is subject to revaluation based on changes in the Canadian/U.S. dollar exchange rate. As at March 31, 2025, we did not have any of our U.S. dollar denominated debt designated as a hedge against our foreign operations that have a U.S. dollar functional currency. As a result of our substantial cash balance, which is largely held in U.S. dollars, following the receipt of proceeds from the sale of EVR and reduction in our U.S. dollar debt in the third quarter of 2024, we expect to be subject to an increased amount of U.S./Canadian dollar exchange rate exposure. Resulting gains or losses on this increased exposure to the U.S. dollar on our U.S. cash balances are recorded through the income statement.

Commodity markets are volatile. Prices can change rapidly and customers can alter shipment plans. This can have a substantial effect on our business and financial results. Continued uncertainty in global markets arising from the macroeconomic outlook and government policy changes, including the imposition of tariffs and the potential for trade disputes, may have a significant positive or negative effect on the prices of the various products we produce, which could affect our business and financial results.

We remain confident in the longer-term outlook for our major commodities; however, ongoing uncertainty related to global economic growth, current geopolitical uncertainty, and the potential impact of monetary policy aimed at curtailing inflation in various jurisdictions, may have an impact on demand and prices for our commodities, on our suppliers and employees, and on global financial markets in the future, which could be material.


The potential imposition of tariffs and countervailing restrictions between the United States and other countries is a fluid and rapidly evolving situation that is being closely monitored by Teck. We sell refined zinc and lead, and specialty metals such as germanium, indium, and sulphur products from Canada into the United States from our Trail Operations in B.C. These products are USMCA compliant. We typically sell a portion of our Red Dog zinc and lead concentrate to our customers in China. The 2025 Red Dog shipping season is not yet underway and we are working actively with our global customers and will continue to manage our sales arrangements to minimize the impact to Red Dog and the rest of our business from possible tariffs.

The potential imposition of tariffs and retaliatory trade measures between the United States and other countries is creating significant uncertainty in global markets which is likely to persist through 2025. While the ultimate outcome of tariffs is still unknown, trade flows are already starting to adjust, inflation expectations are rising and global growth expectations are being revised sharply downwards, which could have a negative impact on metals demand. One consequence of tariff implementation has been a front-loading of global trade. From the fourth quarter of 2024 through the first quarter of 2025, trade flows shifted above the longer-term trend, with notably strong export volumes from China. This has increased pressure on logistics channels, and also resulted in more goods sitting in inventory in consumer markets. As a result, we anticipate a softer period in apparent commodities demand in the second quarter of 2025 as supply chain inventory is reduced, though expect raw material trade to perform better.

In financial markets, tariff-related fears have seen a sharp sell-off in equity markets and industrial commodities, and rising bond yields in many key economies. This has resulted in a sharp drop in consumer confidence and will put increasing strain on the global financial system, which could amplify the organic economic headwinds from slowing trade. Currency markets continue to be volatile, with concerns over the US policy position now expected to result in trend US dollar weakness.

Commodity Prices and Sensitivities

Commodity prices are a key driver of our profit and cash flows. On the supply side, the depleting nature of ore reserves, difficulties in finding new orebodies, the permitting processes and the availability of skilled resources to develop projects, as well as infrastructure constraints, political risk and significant cost inflation, may continue to have a moderating effect on the growth in future production for the industry as a whole.

The sensitivity of our annualized adjusted profit (loss) from continuing operations attributable to shareholders^4^ and adjusted EBITDA^4^ to changes in the Canadian/U.S. dollar exchange rate and commodity prices, before pricing adjustments, based on our current balance sheet, our 2025 mid-range production estimates, current commodity prices and a Canadian/U.S. dollar exchange rate of $1.40, is as follows. Our U.S. dollar exchange sensitivity excludes foreign exchange gain/losses on our U.S. dollar cash and debt balances as these amounts are excluded from our adjusted profit from continuing operations attributable to shareholders^4^ and adjusted EBITDA^4^ calculations.

Changes Estimated Effect of Change on Adjusted Profit (Loss) Attributable to Shareholders2 4 ( in millions) Estimated Effect on Adjusted EBITDA2 4 ( in millions)

Copper (000's tonnes) 527.5 US$0.01/lb.
Zinc (000's tonnes)3 760.0 US$0.01/lb.

All values are in US Dollars.

Notes:

1. Production estimates are subject to change based on market<br>and operating conditions.
2. The effect on our adjusted profit (loss) from continuing operations<br>attributable to shareholders and on adjusted EBITDA of commodity price and exchange rate movements will vary from quarter to quarter depending<br>on sales volumes. Our estimate of the sensitivity of adjusted profit (loss) from continuing operations attributable to shareholders and<br>adjusted EBITDA to changes in the U.S. dollar exchange rate is sensitive to commodity price assumptions.

FINANCIAL INSTRUMENTS AND DERIVATIVES

We hold a number of financial instruments and derivatives that are recorded on our balance sheet at fair value, with gains and losses in each period included in other comprehensive income and profit for the period, as appropriate. The most significant of these instruments are marketable securities and metal-related forward contracts, including those embedded in our silver and gold streaming agreements, QB variable consideration to IMSA, and settlements receivable and payable. Some of our gains and losses on metal-related financial instruments are affected by smelter price participation and are taken into account in determining royalties and other expenses. All are subject to varying rates of taxation depending on their nature and jurisdiction.

GUIDANCE

Our previously disclosed guidance for 2025 is unchanged.
We continue to expect to be within our previously disclosed<br>2025 annual copper and molybdenum production guidance ranges for QB of between 230,000 and 270,000 tonnes and 3,000 and 4,500 tonnes,<br>respectively, albeit at the lower end of the ranges as a result of the maintenance shutdowns, noted above. Our previously disclosed 2025<br>annual net cash unit cost^1^ guidance for QB of US$1.80-$2.15 per pound is unchanged, although we expect to be at the higher<br>end of the range.
--- ---
Our production, unit cost and capital expenditure guidance<br>for 2025, and annual production guidance for 2026-2028 are outlined in the tables below.
--- ---
The guidance ranges below reflect our operating plans, which<br>include known risks and uncertainties. Events such as extreme weather, unplanned or extended operational shut-downs and other disruptions<br>could impact actual results beyond these estimates. Our unit costs are calculated based on production guidance volumes and variances from<br>estimated production ranges will impact unit costs. Our disclosed guidance ranges for capital expenditures do not include post-sanction<br>capital expenditures for the unsanctioned near-term growth projects, noted above. Our disclosed production guidance ranges also do not<br>include the production associated with these unsanctioned projects. Guidance will be updated at the time a sanction decision is made.
--- ---
Our unit cost guidance for 2025 reflects actions taken across<br>our operations to reduce costs, and embedding our management operating system across our operations to improve consistency and efficiency.
--- ---
As a result of structural cost reductions across our business,<br>we continue to expect our 2025 general and administration and research and innovation costs to decrease by approximately 15% and 35%,<br>respectively, compared to 2024. This excludes investment in the implementation of a new ERP system across the company, which we expect<br>to commence in 2025. This will be a multi-year program and our previously disclosed guidance included capital expenditures of $80–$100<br>million associated with the ERP implementation in 2025. Although we continue to expect to spend $80–$100 million in 2025, we now<br>expect most of these expenditures to be expensed rather than capitalized and as a result, we have removed these costs from our capital<br>expenditure guidance in the table below.
--- ---
Based on our current elevated cash and cash equivalents balance<br>resulting from the receipt of proceeds from the sale of the steelmaking coal business, we expect to have higher investment interest income<br>for the foreseeable future.

AREAS OF JUDGMENT AND CRITICAL ACCOUNTING ESTIMATES


In preparing our consolidated financial statements, we make judgments in applying our accounting policies. The judgments that have the most significant effect on the amounts recognized in our financial statements include the assessment of impairment indicators, the determination of assets held for sale and discontinued operations, the determination of the available for use date for property, plant and equipment, accounting for joint arrangements, streaming transactions and the accounting for income taxes. In addition, we make assumptions about the future in deriving estimates used in preparing our consolidated financial statements. Sources of estimation uncertainty include estimates used to determine the recoverable amounts of long-lived assets, recoverable reserves and resources, the provision for income taxes and the related deferred tax assets and liabilities, and the valuation of other assets and liabilities including decommissioning and restoration provisions. These areas of judgment and critical accounting estimates are consistent with those reported in our 2024 annual consolidated financial statements and Management's Discussion and Analysis, except as outlined below.

ADOPTION OF NEW ACCOUNTING STANDARDS AND ACCOUNTING DEVELOPMENTS


Amendmentsto IFRS 9 and IFRS 7 – Contracts Referencing Nature-dependent Electricity


In December 2024, the IASB issued Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7. These amendments aimed to ensure that nature-dependent electricity contracts, where contractual features can expose a company to variability in the underlying amount of electricity because the source of electricity generation depends on uncontrollable natural conditions, are appropriately reflected in the financial statements. The amendments include clarifying the application of the “own use” requirements to these contracts in assessing whether derivative accounting is required, permitting hedge accounting if these contracts are used as hedging instruments and requiring new disclosures that discuss the effect of these contracts on a company’s financial performance and cash flows.

The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted. The clarifications regarding the “own use” requirements are applied retrospectively, but the guidance permitting hedge accounting is applied prospectively to new hedging relationships designated on or after the date of initial application. We are currently assessing the effect of these amendments on our consolidated financial statements.

Amendments to IFRS 9 and IFRS 7**– Amendments to the Classification and Measurement of Financial Instruments**


In May 2024, the IASB issued Amendmentsto the Classification and Measurement of Financial Instruments – Amendments to IFRS 9 and IFRS 7. These amendments updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 FinancialInstruments: Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. The IASB added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs, and amended disclosures relating to equity instruments designated at fair value through other comprehensive income.

The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted. We are currently assessing the effect of these amendments on our consolidated financial statements.

IFRS 18 – Presentation and Disclosure in Financial Statements


In April 2024, the IASB issued IFRS 18, Presentation and Disclosure inFinancial Statements (IFRS 18), which replaces IAS 1, Presentation of Financial Statements. IFRS 18 introduces a specified structure for the income statement by requiring income and expenses to be presented into the three main categories of operating, investing and financing, and by specifying certain defined totals and subtotals. An entity may use certain subtotals of income and expenses in public communications outside the financial statements to communicate management’s view of an aspect of the financial performance of the entity as a whole to users, and these subtotals are not specifically required by IFRS Accounting Standards. IFRS 18 requires companies to disclose explanations around these measures, which are referred to as management-defined performance measures. IFRS 18 also provides additional guidance on principles of aggregation and disaggregation that apply to the primary financial statements and the notes. IFRS 18 will not affect the recognition and measurement of items in the financial statements, nor will it affect which items are classified in other comprehensive income and how these items are classified. The standard is effective for reporting periods beginning on or after January 1, 2027, including for interim financial statements. Retrospective application is required and early application is permitted. We are currently assessing the effect of this new standard on our consolidated financial statements.

OUTSTANDING SHARE DATA

As at April 23, 2025, there were 490.4 million Class B subordinate voting shares and 7.6 million Class A common shares outstanding. In addition, there were approximately 5.8 million share options outstanding with exercise prices ranging between $5.34 and $70.34 per share. More information on these instruments and the terms of their conversion is set out in Note 29 of our 2024 audited consolidated financial statements.



INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Any system of internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

There have been no significant changes in our internal controls during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting.

USE OF NON-GAAP FINANCIAL MEASURES ANDRATIOS

Our annual financial statements are prepared in accordance with IFRS^®^ Accounting Standards as issued by the International Accounting Standards Board (IASB). Our interim financial results are prepared in accordance with IAS 34, Interim Financial Reporting (IAS 34). This document refers to a number of non-GAAP financial measures and non-GAAP ratios, which are not measures recognized under IFRS Accounting Standards and do not have a standardized meaning prescribed by IFRS Accounting Standards or by Generally Accepted Accounting Principles (GAAP) in the United States.

The non-GAAP financial measures and non-GAAP ratios described below do not have standardized meanings under IFRS Accounting Standards, may differ from those used by other issuers, and may not be comparable to similar financial measures and ratios reported by other issuers. These financial measures and ratios have been derived from our financial statements and applied on a consistent basis as appropriate. We disclose these financial measures and ratios because we believe they assist readers in understanding the results of our operations and financial position and provide further information about our financial results to investors. These measures should not be considered in isolation or used as a substitute for other measures of performance prepared in accordance with IFRS Accounting Standards.

Adjusted profit (loss) from continuing operationsattributable to shareholders – For adjusted profit from continuing operations attributable to shareholders, we adjust profit from continuing operations attributable to shareholders as reported to remove the after-tax effect of certain types of transactions that reflect measurement changes on our balance sheet or are not indicative of our normal operating activities.

EBITDA – EBITDA is profit before net finance expense, provision for income taxes, and depreciation and amortization.

Adjusted EBITDA – Adjusted EBITDA is EBITDA before the pre-tax effect of the adjustments that we make to adjusted profit from continuing operations attributable to shareholders as described above.

Adjusted profit from continuing operations attributable to shareholders, EBITDA and Adjusted EBITDA highlight items and allow us and readers to analyze the rest of our results more clearly. We believe that disclosing these measures assists readers in understanding the ongoing cash-generating potential of our business in order to provide liquidity to fund working capital needs, service outstanding debt, fund future capital expenditures and investment opportunities, and pay dividends.


Gross profit before depreciation and amortization – Gross profit before depreciation and amortization is gross profit with depreciation and amortization expense added back. We believe this measure assists us and readers to assess our ability to generate cash flow from our reportable segments or overall operations.

Gross profit margins before depreciationand amortization – Gross profit margins before depreciation and amortization are gross profit before depreciation and amortization, divided by revenue for each respective reportable segment. We believe this measure assists us and readers to compare margins on a percentage basis among our reportable segments.

Total cash unit costs – Total cash unit costs for our copper and zinc operations includes adjusted cash costs of sales, as described below, plus the smelter and refining charges added back in determining adjusted revenue. This presentation allows a comparison of total cash unit costs, including smelter charges, to the underlying price of copper or zinc in order to assess the margin for the mine on a per unit basis.

Net cash unit costs – Net cash unit costs of principal product, after deducting co-product and by-product margins, are also a common industry measure. By deducting the co- and by-product margin per unit of the principal product, the margin for the mine on a per unit basis may be presented in a single metric for comparison to other operations.

Adjusted cash cost of sales – Adjusted cash cost of sales for our copper and zinc operations is defined as the cost of the product delivered to the port of shipment, excluding depreciation and amortization charges, any one-time collective agreement charges or inventory write-down provisions and by-product cost of sales. It is common practice in the industry to exclude depreciation and amortization, as these costs are non-cash, and discounted cash flow valuation models used in the industry substitute expectations of future capital spending for these amounts.

Cash margins for by-products – Cash margins for by-products is revenue from by- and co-products, less any associated cost of sales of the by- and co-product. In addition, for our copper operations, by-product cost of sales also includes cost recoveries associated with our streaming transactions.

Adjusted revenue – Adjusted revenue for our copper and zinc operations excludes the revenue from co-products and by-products, but adds back the processing and refining charges to arrive at the value of the underlying payable pounds of copper and zinc. Readers may compare this on a per unit basis with the price of copper and zinc on the LME.

The debt-related measures outlined below are disclosed as we believe they provide readers with information that allows them to assess our credit capacity and the ability to meet our short- and long-term financial obligations

Total debt – Total debt is the sum of debt plus lease liabilities, including the current portions of debt and lease liabilities.

Net debt (cash) – Net debt (cash) is total debt, less cash and cash equivalents. Net cash is the amount by which our cash balance exceeds our total debt balance.

Net debt to net debt-plus-equity ratio – Net debt to net debt-plus-equity ratio is net debt divided by the sum of net debt plus total equity, expressed as a percentage.

Net debt to adjusted EBITDA ratio – Net debt to adjusted EBITDA ratio is net debt divided by adjusted EBITDA for the 12 months ended at the reporting period, expressed as the number of times adjusted EBITDA needs to be earned to repay the net debt.

Adjusted basic earnings (loss) per sharefrom continuing operations – Adjusted basic earnings per share from continuing operations is adjusted profit from continuing operations attributable to shareholders divided by average number of shares outstanding in the period.

Adjusted diluted earnings (loss) per sharefrom continuing operations – Adjusted diluted earnings per share from continuing operations is adjusted profit from continuing operations attributable to shareholders divided by average number of fully diluted shares in a period.


Total cash unit costs per pound –Total cash unit costs per pound is a non-GAAP ratio comprised of adjusted cash cost of sales divided by payable pounds sold plus smelter processing charges divided by payable pounds sold.

Net cash unit costs per pound – Net cash unit costs per pound is a non-GAAP ratio comprised of (adjusted cash cost of sales plus smelter processing charges less cash margin for by-products) divided by payable pounds sold. There is no similar financial measure in our consolidated financial statements with which to compare. Adjusted cash cost of sales is a non-GAAP financial measure.

Cash margins for by-products per pound – Cash margins for by-products per pound is a non-GAAP ratio comprised of cash margins for by-products divided by payable pounds sold.

Statements concerning future production costs or volumes are based on numerous assumptions regarding operating matters and on assumptions that demand for products develops as anticipated, that customers and other counterparties perform their contractual obligations, that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, interruption in transportation or utilities, or adverse weather conditions, and that there are no material unanticipated variations in the cost of energy or supplies. The foregoing list of assumptions is not exhaustive. Events or circumstances could cause actual results to vary materially.

Factors that may cause actual results to vary materially include, but are not limited to, changes in commodity and power prices; changes in market demand for our products; changes in interest and currency exchange rates; acts of governments and the outcome of legal proceedings; the imposition of tariffs, import or export restrictions, or other trade barriers or retaliatory measures by foreign or domestic governments; inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral reserves and resources); operational difficulties (including failure of plant, equipment or processes to operate in accordance with specifications or expectations, cost escalation, unavailability of labour, materials and equipment); government action or delays in the receipt of government approvals; changes in royalty or tax rates; industrial disturbances or other job action; adverse weather conditions; unanticipated events related to health, safety and environmental matters; union labour disputes; political risk; social unrest; failure of customers or counterparties (including logistics suppliers) to perform their contractual obligations; changes in our credit ratings; unanticipated increases in costs to construct our development projects; difficulty in obtaining permits; inability to address concerns regarding permits or environmental impact assessments; and changes or further deterioration in general economic conditions. The amount and timing of capital expenditures is depending upon, among other matters, being able to secure permits, equipment, supplies, materials and labour on a timely basis and at expected costs. Certain operations and projects are not controlled by us; schedules and costs may be adjusted by our partners, and timing of spending and operation of the operation or project is not in our control. Certain of our other operations and projects are operated through joint arrangements where we may not have control over all decisions, which may cause outcomes to differ from current expectations. Ongoing monitoring may reveal unexpected environmental conditions at our operations and projects that could require additional remedial measures. Production at our QB and Red Dog Operations may also be impacted by water levels

Notes to Condensed Interim Consolidated Financial Statements

(Unaudited)

1. BASIS OF PREPARATION

We prepare our annual consolidated financial statements in accordance with IFRS^®^ Accounting Standards as issued by the International Accounting Standards Board (IASB). These condensed interim consolidated financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting (IAS 34).

These condensed interim consolidated financial statements should be read in conjunction with our most recent annual financial statements. These condensed interim consolidated financial statements follow the same accounting policies and methods of application as our most recent annual financial statements. On April 23, 2025, the Audit Committee of the Board of Directors authorized these financial statements for issuance.

2. NEW IFRS ACCOUNTING STANDARDS AND AMENDMENTS

Amendmentsto IFRS 9 and IFRS 7 – Contracts Referencing Nature-dependent Electricity


In December 2024, the IASB issued Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 9 and IFRS 7. These amendments aimed to ensure that nature-dependent electricity contracts, where contractual features can expose a company to variability in the underlying amount of electricity because the source of electricity generation depends on uncontrollable natural conditions, are appropriately reflected in the financial statements. The amendments include clarifying the application of the “own use” requirements to these contracts in assessing whether derivative accounting is required, permitting hedge accounting if these contracts are used as hedging instruments and requiring new disclosures that discuss the effect of these contracts on a company’s financial performance and cash flows.

The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted. The clarifications regarding the “own use” requirements are applied retrospectively, but the guidance permitting hedge accounting is applied prospectively to new hedging relationships designated on or after the date of initial application. We are currently assessing the effect of these amendments on our consolidated financial statements.

Amendments to IFRS 9 and IFRS 7**– Amendments to the Classification and Measurement of Financial Instruments**


In May 2024, the IASB issued Amendmentsto the Classification and Measurement of Financial Instruments – Amendments to IFRS 9 and IFRS 7. These amendments updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 Financial Instruments:Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. The IASB added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs, and amended disclosures relating to equity instruments designated at fair value through other comprehensive income.

The amendments are effective for annual periods beginning on or after January 1, 2026, with early application permitted. We are currently assessing the effect of these amendments on our consolidated financial statements.

2. NEW IFRS ACCOUNTING STANDARDS AND AMENDMENTS, continued

IFRS 18 – Presentation and Disclosure in Financial Statements


In April 2024, the IASB issued IFRS 18, Presentation and Disclosure inFinancial Statements (IFRS 18), which replaces IAS 1, Presentation of Financial Statements. IFRS 18 introduces a specified structure for the income statement by requiring income and expenses to be presented into the three main categories of operating, investing and financing, and by specifying certain defined totals and subtotals. An entity may use certain subtotals of income and expenses in public communications outside the financial statements to communicate management’s view of an aspect of the financial performance of the entity as a whole to users, and these subtotals are not specifically required by IFRS Accounting Standards. IFRS 18 requires companies to disclose explanations around these measures, which are referred to as management-defined performance measures. IFRS 18 also provides additional guidance on principles of aggregation and disaggregation that apply to the primary financial statements and the notes. IFRS 18 will not affect the recognition and measurement of items in the financial statements, nor will it affect which items are classified in other comprehensive income and how these items are classified. The standard is effective for reporting periods beginning on or after January 1, 2027, including for interim financial statements. Retrospective application is required and early application is permitted. We are currently assessing the effect of this new standard on our consolidated financial statements.

3. SALE OF STEELMAKING COAL BUSINESS AND DISCONTINUED OPERATIONS
a) Sale of steelmaking coal business
--- ---

In 2024, we completed the sale of our steelmaking coal business. In January of 2024, we sold a minority stake of our interest in our steelmaking coal business, Elk Valley Resources (EVR), to Nippon Steel Corporation (NSC) and POSCO. NSC acquired a 20% interest in EVR in exchange for its 2.5% interest in the Elkview Operations plus $1.7 billion (US$1.3 billion) in cash. POSCO exchanged its 2.5% interest in the Elkview Operations and its 20% interest in the Greenhills Operations for a 3% interest in EVR. These transactions were accounted for as equity transactions with non-controlling interests, reducing retained earnings by $1.5 billion and increasing non-controlling interests balances.

In July of 2024, we completed the sale of our remaining 77% interest in EVR to Glencore plc (Glencore), for which we received cash proceeds of $9.9 billion (US$7.3 billion). As a result, we derecognized the corresponding assets and liabilities of EVR. Profit from the steelmaking coal business is disclosed as part of profit from discontinued operations on our consolidated statement of income.

Pursuant to the terms of the steelmaking coal business sale transaction, Teck agreed to indemnify Glencore for a portion of certain water related liabilities. On July 10, 2024, the Public Prosecution Service of Canada charged Teck Coal Limited with five counts of violating s.36(3) of the Fisheries Act. Glencore notified Teck that it is seeking indemnification with respect to liabilities arising out of these charges.

4. REVENUE

The following table shows our revenue disaggregated by major product type and by reportable segment (Note 11). A reportable segment can have revenue from more than one commodity, as it can include an operation that produces more than one product. Intra-segment revenue is accounted for at current market prices as if the sales were made to arm’s-length parties and are eliminated on consolidation.

As a result of the sale of our steelmaking coal business in July of 2024, we no longer present the associated revenue in the tables below. Revenue related to the steelmaking coal business is disclosed as part of Note 3, Sale of Steelmaking Coal Business and Discontinued Operations.

All values are in US Dollars.

The fair values of debt are determined using market values, if available, and discounted cash flows based on our cost of borrowing where market values are not available. The latter are considered Level 2 fair value measurements with significant other observable inputs on the fair value hierarchy (Note 14).

a) Notes Purchased

In the first quarter of 2025, we purchased US$15 million aggregate principal amount of our outstanding term notes (US$1 million of the 3.9% notes due 2030, US$7 million of the 6.125% notes due 2035, US$4 million of the 6.0% notes due 2040, and US$3 million of the 6.25% notes due 2041) via open market repurchases. The total cash cost of the purchases was $22 million (US$15 million), which was funded from cash on hand.

b) QB Project Financing Facility
--- ---

As at March 31, 2025, the limited recourse QB project financing facility had a balance of US$1.9 billion. Amounts drawn under the facility bear interest at Term SOFR plus applicable margins that vary over time. The facility is being repaid in 17 equal semi-annual instalments of US$147 million, which began on June 15, 2023. The facility was guaranteed pre-final completion on a several basis by Teck and SMM/SC pro rata to the respective equity interests in the Series A shares of QBSA. The project has met all the completion requirements and achieved completion in March 2025. As a result, these guarantees have been released.


c) Revolving Credit Facility

We maintain a US$3.0 billion sustainability-linked revolving credit facility maturing October 2029. The facility has pricing adjustments where the cost will increase, decrease or remain unchanged based on our sustainability performance. Our sustainability performance over the term of the facility is measured by non-financial variables that are specific to our greenhouse gas emissions intensity, the percentage of women in our workforce and our high-potential safety incidents.

As at March 31, 2025, the facility was undrawn. Any amounts drawn under this facility can be repaid at any time and are due in full at maturity. Amounts outstanding under the facility bear interest at Term SOFR plus an applicable margin based on credit ratings and our sustainability performance, as described above. This facility requires our total net debt-to-capitalization ratio to not exceed 0.60 to 1.0. Following the sale of the steelmaking coal business in July 2024, cash and cash equivalents have increased significantly and as a result, our cash balances were greater than our debt balances at March 31, 2025. Therefore, we do not exceed the required net debt-to-capitalization ratio. This facility does not have an earnings or cash flow-based financial covenant, a credit rating trigger or a general material adverse effect borrowing condition.


In addition to that financial covenant, the facility is subject to customary covenants including limits on subsidiary debt, change of control repayment requirements, and the prohibition on agreements that may restrict subsidiary dividend payments or loan repayments to Teck. Breach of these covenants could lead to an inability to borrow under the facility, or an enforcement action by lenders, including accelerating any outstanding debt repayment.


We maintain uncommitted bilateral credit facilities primarily for the issuance of letters of credit to support our future reclamation obligations. As at March 31, 2025, we had $1.6 billion (December 31, 2024 – $1.5 billion) of letters of credit outstanding. We also had $455 million in surety bonds outstanding at March 31, 2025 (December 31, 2024 – $441 million) to support current and future reclamation obligations.

10. EQUITY, continued
c) Dividends
--- ---

In the first quarter of 2025, we declared and paid dividends on our Class A common and Class B subordinate voting shares of $0.125 per share, totalling $63 million.

d) Normal Course Issuer Bids

On occasion, we purchase and cancel Class B subordinate voting shares pursuant to normal course issuer bids that allow us to purchase up to a specified maximum number of shares over a one-year period.

In November 2024, we renewed our regulatory approval to conduct a normal course issuer bid, under which we may purchase up to 40 million Class B subordinate voting shares during the period from November 22, 2024 to November 21, 2025. All purchased shares will be cancelled.

During the three months ended March 31, 2025, we purchased 6,400,551 Class B subordinate voting shares for $389 million, which was recorded as part of equity. The $389 million includes an accrual of $7 million related to tax on repurchases of equity. Of the shares purchased, $380 million was paid in cash for the cancellation of 6,350,551 Class B subordinate voting shares inclusive of $6 million cash for the share cancellations accrued as at December 31, 2024 which settled in the quarter. Subsequent to March 31, 2025, $8 million was paid in cash for the cancellation of the remaining 150,000 Class B subordinate voting shares.

During the three months ended March 31, 2024, we purchased 1,431,300 Class B subordinate voting shares for $80 million, which was recorded as part of equity. Of the shares purchased, $74 million was paid in cash for the cancellation of 1,316,600 Class B subordinate voting shares.

11. SEGMENTED INFORMATION

Based on the primary products we produce, we have two reportable segments that we report to our President and Chief Executive Officer – copper and zinc. Corporate activities are not considered a reportable segment and are included as a reconciliation to total consolidated results. These corporate activities include all of our initiatives in other commodities and groups that provide administrative, technical, financial and other support to our reportable segments. Operating income (expense) - other includes general and administration, exploration, research and innovation and other operating income (expense). Sales between segments are carried out on terms that arm’s-length parties would use. Total assets do not include intra-group receivables between segments. Deferred tax assets have been allocated among segments.

As a result of the sale of our steelmaking coal business in July of 2024, we no longer present the associated steelmaking coal segment in the tables below. The segmented information related to the steelmaking coal business is disclosed as part of Note 3, Sale of Steelmaking Coal Business and Discontinued Operations.

12. CONTINGENCIES

We consider provisions for all of our outstanding and pending legal claims to be adequate. The final outcome with respect to actions outstanding or pending as at March 31, 2025, or with respect to future claims, cannot be predicted with certainty. Significant contingencies not disclosed elsewhere in the notes to our consolidated financial statements are as follows:

Upper Columbia River Basin

Teck American Inc. (TAI) continues studies under the 2006 settlement agreement with the U.S. Environmental Protection Agency (EPA) to conduct a remedial investigation on the Upper Columbia River in Washington State.

In parallel, the Lake Roosevelt litigation involving Teck Metals Limited (TML) by the State of Washington and the

Confederated Tribes of the Coleville Reservation (CCT) in the Federal District Court for the Eastern District of Washington continues. The case relates to historic discharges of slag and effluent from TML’s Trail metallurgical facility to the Upper Columbia River. TML prevailed against the plaintiffs on citizen suit claims, seeking injunctive relief, statutory penalties and attorney’s fees. In December 2012, on the basis of stipulated facts agreed between TML and the plaintiffs, the Court found in favour of the plaintiffs in phase one of the case, issuing a declaratory judgment that TML is liable under the ComprehensiveEnvironmental Response, Compensation, and Liability Act (CERCLA) for the plaintiffs' response costs, the amounts of which were determined in the second phase of the case. Additional response costs not yet claimed may be recoverable. The third and final phase of the case pertains to the plaintiffs’ claims for natural resource damages.

In 2022, TML filed two motions for summary judgment in respect of the CERCLA natural resource damages claims, which were denied. Based on one of those rulings, in the first quarter of 2023, TML filed a motion seeking a ruling that the plaintiffs’ natural resource damages claims under CERCLA are not fully developed and they should therefore be dismissed. The motion was denied and TML sought motions seeking reconsideration and certification for an interlocutory appeal to the Ninth Circuit Court of Appeals, both of which were denied.

In October 2023, TML filed a motion for partial summary judgment on CCT’s tribal service loss claim. CCT’s tribal services loss claim comprises the bulk of CCT’s outstanding individual claims against TML except for natural resource damages assessment costs. On February 6, 2024, the court granted TML’s motion and dismissed CCT’s claim on the basis that tribal service loss claims are not cognizable as natural resource damages claims under CERCLA. The CCT filed a motion seeking reconsideration of the dismissal or in the alternative certification for an interlocutory appeal to the Ninth Circuit Court of Appeals. The trial court denied reconsideration but certified the matter for interlocutory review by the Ninth Circuit Court of Appeals. The Ninth Circuit court heard the interlocutory appeal on April 17, 2025. A decision of the court is pending.

The previously scheduled February 2024 trial with respect to natural resource damages and assessment costs has been postponed pending the Ninth Circuit Court’s decision on the CCT’s dismissed tribal service loss claim and a new trial date has not yet been scheduled.

Until the studies contemplated by the EPA settlement agreement and additional natural resource damage assessments are completed, it is not possible to estimate the extent and cost, if any, of any additional remediation that may be required by the EPA or restoration that may be demanded by the natural resource trustees or to assess the extent of Teck's potential liability for damages. The EPA studies may conclude, on the basis of risk, cost, technical feasibility or other grounds, that no remediation other than some additional residential soil removal should be undertaken. If other remediation is required, damage to natural resources are proved, and if the CCT’s dismissed tribal service loss claim is revived and subsequently proved, the cost of that remediation and restoration and compensation for natural resource damages may be material.

13. SEASONALITY OF SALES

Due to ice conditions, the port serving our Red Dog mine is normally only able to ship concentrates from July to October each year. As a result, zinc and lead concentrate sales volumes are generally higher in the third and fourth quarter of each year than in the first and second quarter. Depending on commodity prices, this could result in Red Dog’s profits and cash flows being higher in the last two quarters of the year as finished inventories are sold.

14. FAIR VALUE MEASUREMENTS

Certain of our financial assets and liabilities are measured at fair value on a recurring basis and classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Certain non-financial assets and liabilities may also be measured at fair value on a non-recurring basis and classified in their entirety based on the lowest level of input that is significant to the fair value measurement. There are three levels of the fair value hierarchy that prioritize the inputs to valuation techniques used to measure fair value, with Level 1 inputs having the highest priority. The levels and the valuation techniques used to value our financial assets and liabilities are described below:

Level 1 – Quoted Prices in Active Markets for Identical Assets

Level 1 inputs are unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Certain cash equivalents, certain marketable equity securities and certain debt securities are valued using quoted market prices in active markets. Accordingly, these items are included in Level 1 of the fair value hierarchy.

Level 2 – Significant Observable Inputs Other than Quoted Prices

Level 2 inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Derivative instruments and embedded derivatives are included in Level 2 of the fair value hierarchy, as they are valued using pricing models or discounted cash flow models. These models require a variety of inputs, including, but not limited to, market prices, forward price curves, yield curves and credit spreads. These inputs are obtained from or corroborated with the market. Also included in Level 2 are settlement receivables and settlement payables from provisional pricing on concentrate sales and purchases and certain refined metal sales because they are valued using quoted market prices derived based on forward curves for the respective commodities.

Level 3 – Significant Unobservable Inputs

Level 3 inputs are unobservable (supported by little or no market activity).

We include investments in certain equity securities in non-public companies in Level 3 of the fair value hierarchy because they trade infrequently and have little price transparency.

14. FAIR VALUE MEASUREMENTS, continued

The fair values of our financial assets and liabilities measured at fair value on a recurring basis at March 31, 2025 and December 31, 2024, are summarized in the following table:

(CAD$ in millions) March 31, 2025 December 31, 2024
Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total
Financial assets
Cash equivalents $ 3,554 $ $ $ 3,554 $ 5,244 $ $ $ 5,244
Marketable and other equity securities 105 192 297 118 189 307
Debt securities 225 225 220 220
Settlement receivables 1,476 1,476 1,456 1,456
Derivative instruments and embedded derivatives 214 214 168 168
$ 3,884 $ 1,690 $ 192 $ 5,766 $ 5,582 $ 1,624 $ 189 $ 7,395
Financial liabilities
Derivative instruments and embedded derivatives $ $ 188 $ $ 188 $ $ 179 $ $ 179
Settlement payables 76 76 70 70
$ $ 264 $ $ 264 $ $ 249 $ $ 249

Equity securities in non-public companies included in Level 3 of the fair value hierarchy are initially measured at fair value, with cost of the investment taken as the best estimate of fair value and subsequently measured based on an implied value of the underlying business.

Unless disclosed elsewhere in our consolidated financial statements (Note 8 and Note 9), the fair value of the remaining financial assets and financial liabilities approximate their carrying value.
