Caution Regarding Forward-Looking Statements
Both these slides and the accompanying oral presentation contain certain forward-looking information and forward-looking statements as defined in applicable securities laws (collectively referred to as forward-looking statements). These statements relate to future events or our future performance. All
statements other than statements of historical fact are forward-looking statements. The use of any of the words “anticipate”, “plan”, “continue”, “estimate”, “expect”, “may”, “will”, “project”, “predict”, “potential”, “should”, “believe” and similar expressions is intended to identify forward-looking statements.
These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking statements. These statements speak only as of the date of this presentation.
These forward-looking statements include, but are not limited to, statements concerning: forecast production; forecast operating costs, unit costs, capital costs and other costs; sales forecasts; our strategies, objectives and goals; expectations regarding future prices and price volatility for copper, zinc,
steelmaking coal and other products and commodities that we produce and sell; expectations regarding the demand for and supply of copper, zinc and steelmaking coal; expected growth in copper production, including the potential for Teck to become a top 10 copper producer and our expectation that
QB2 will double our consolidated copper production; our sustainability goals, including our emissions reduction targets and our goal to be a nature positive company by 2030 and the pathway we propose to get there; our expectations regarding our QB2 project, including expectations regarding
production, timing to reach full capacity, capital costs, operating costs, capacity, mine life, strip ratios, reserves and resources, and tax treatment; planned or forecast production levels and future production of our operations and other development projects, including the statements relating to our copper
growth pipeline; QB2 illustrative net cash flows and other forecasts on the “Cash Flow Inflection” slide; statements related to our capital allocation framework, including statements regarding potential returns to shareholders, potential cash flows and allocation of funds; and all guidance included in the
Appendix or elsewhere in this presentation, including, but not limited to, guidance relating to production, sales and unit cost, capital expenditure and water treatment.
Inherent in forward-looking statements are risks and uncertainties beyond our ability to predict or control, including, without limitation, risks: that may affect our operating or capital plans; that are generally encountered in the permitting and development of mineral properties such as unusual or
unexpected geological formations; associated with volatility in financial and commodities markets and global uncertainty; associated with the COVID-19 pandemic; associated with unanticipated metallurgical difficulties; relating to delays associated with permit appeals or other regulatory processes,
ground control problems, adverse weather conditions or process upsets or equipment malfunctions; associated with any damage to our reputation; associated with labour disturbances and availability of skilled labour; associated with fluctuations in the market prices of our principal commodities or of our
principal inputs; associated with changes to the tax and royalty regimes in which we operate; created through competition for mining properties; associated with lack of access to capital or to markets; associated with mineral reserve or resource estimates; posed by fluctuations in exchange rates and
interest rates, as well as general economic conditions and inflation; associated with changes to our credit ratings; associated with our material financing arrangements and our covenants thereunder; associated with climate change, environmental compliance, changes in environmental legislation and
regulation, and changes to our reclamation obligations; associated with procurement of goods and services for our business, projects and operations; associated with non-performance by contractual counterparties; associated with potential disputes with partners and co-owners; associated with
operations in foreign countries; associated with information technology; risks associated with tax reassessments and legal proceedings; relating to the separation of Teck announced on February 21, 2023 (the Separation) or the related transactions with Nippon Steel Corporation and POSCO, including
that the transactions will not be completed on the terms and conditions, or on the timing, currently contemplated, or at all; the possibility of adverse reactions or changes in business relationships resulting from the announcement or completion of the Separation; relating to business disruption during the
pendency of or following the Separation or diversion of management time; and other risk factors detailed in our Annual Information Form. Declaration and payment of dividends and capital allocation are the discretion of the Board, and our dividend policy and capital allocation framework will be reviewed
regularly and may change. Dividends and share repurchases can be impacted by share price volatility, negative changes to commodity prices, availability of funds to purchase shares, alternative uses for funds and compliance with regulatory requirements.
Actual results and developments are likely to differ, and may differ materially, from those expressed or implied by the forward-looking statements contained in this presentation. Such statements are based on a number of assumptions that may prove to be incorrect, including, but not limited to,
assumptions regarding: general business and economic conditions; commodity and power prices; assumption that QB2 becomes fully producing within the periods set out in this presentation; the supply and demand for, deliveries of, and the level and volatility of prices of copper, zinc and steelmaking
coal and our other metals and minerals, as well as inputs required for our operations; the timing of receipt of permits and other regulatory and governmental approvals for our development projects and other operations, including mine extensions; our costs of production, and our production and
productivity levels, as well as those of our competitors; availability of water and power resources for our projects and operations; credit market conditions and conditions in financial markets generally; our ability to procure equipment and operating supplies and services in sufficient quantities on a timely
basis; the availability of qualified employees and contractors for our operations, including our new developments and our ability to attract and retain skilled employees; the satisfactory negotiation of collective agreements with unionized employees; the impact of changes in Canadian-U.S. dollar
exchange rates, Canadian dollar-Chilean Peso exchange rates and other foreign exchange rates on our costs and results; the accuracy of our mineral and steelmaking coal reserve and resource estimates (including with respect to size, grade and recoverability) and the geological, operational and price
assumptions on which these are based; tax benefits and tax rates; the impacts of the COVID-19 pandemic and the government response thereto on our operations and projects and on global markets; and our ongoing relations with our employees and with our business and joint venture
partners. Assumptions regarding QB2 include current project assumptions and assumptions contained in the final feasibility study, as well as there being no further unexpected material and negative impact to the various contractors, suppliers and subcontractors for the QB2 project relating to COVID-
19 or otherwise that would impair their ability to provide goods and services as anticipated. Expectations regarding our operations are based on numerous assumptions regarding the operations. Statements concerning future production costs or volumes are based on numerous assumptions of
management 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, COVID-19, interruption in transportation or utilities, or adverse weather conditions; and that there are no material unanticipated variations in the cost of energy or supplies. Our sustainability goals are based on a number of additional assumptions, including
regarding the availability and effectiveness of technologies needed to achieve our sustainability goals and priorities; the availability of clean energy sources and zero-emissions alternatives for transportation on reasonable terms; our ability to implement new source control or mine design strategies on
commercially reasonable terms without impacting production objectives; our ability to successfully implement our technology and innovation strategy; and the performance of new technologies in accordance with our expectations.
Teck cautions that the foregoing list of important factors and assumptions is not exhaustive. Other events or circumstances could cause our actual results to differ materially from those estimated or projected and expressed in, or implied by, our forward-looking statements. See also the risks and
assumptions discussed under “Risk Factors” in our most recent Annual Information Form and in subsequent filings, which can be found under our profile on SEDAR (www.sedar.com) and on EDGAR (www.sec.gov). Except as required by law, we undertake no obligation to update publicly or otherwise
revise any forward-looking statements or the foregoing list of assumptions, risks or other factors, whether as a result of new information, future events or otherwise.
Scientific and technical information in this presentation and related appendices regarding our QB2 property was reviewed and approved by Rodrigo Alves Marinho, P.Geo., an employee of Teck and a Qualified Person under National Instrument 43-101.

Our capital allocation framework describes how we allocate funds to sustaining and growth capital, maintaining solid investment grade credit metrics and returning excess cash to shareholders. This framework reflects our
intention to make additional returns to shareholders by supplementing our base dividend with at least an additional 30% of available cash flow after certain other repayments and expenditures have been made. For this
purpose, we define available cash flow (ACF) as cash flow from operating activities after interest and finance charges, lease payments and distributions to non-controlling interests less: (i) sustaining capital and capitalized
stripping; (ii) committed growth capital; (iii) any cash required to adjust the capital structure to maintain solid investment grade credit metrics; (iv) our base $0.50 per share annual dividend; and (v) any share repurchases
executed under our annual buyback authorization. Proceeds from any asset sales may also be used to supplement available cash flow. Any additional cash returns will be made through share repurchases and/or
supplemental dividends depending on market conditions at the relevant time.

1. Reserves and resources as at December 31, 2021.
2. Production guidance includes cathode production at Quebrada Blanca. Guidance for 2024-2026 is on an annual basis.
3. As a result of recent changes to IFRS, we are required to recognize sales proceeds and related costs associated with products
sold during the ramp-up and commissioning phase of QB2 through earnings rather than capitalizing these amounts. We expect
this to increase our unit operating costs for QB2 during ramp-up. Once QB2 is running at full production rates, we expect the
average net cash unit costs will be US$1.40- 1.60 per pound.
Slide 11: Transformational Growth Rebalances Portfolio to Copper

Non-GAAP Financial Measures and Ratios
Our financial results are prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board. This presentation includes reference to certain non-GAAP financial measures and
non-GAAP ratios, which are not measures recognized under IFRS, do not have a standardized meaning prescribed by IFRS and may not be comparable to similar financial measures or ratios disclosed 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 in substitute for other measures of performance prepared in accordance with IFRS. For more
information on our use of non-GAAP financial measures and ratios, see the section titled “Use of Non-GAAP Financial Measures and Ratios” in our most recent Management Discussion & Analysis, which is incorporated by reference herein and is
available on SEDAR at www.sedar.com. Additional information on certain non-GAAP ratios is below.
Non-GAAP Ratios
Adjusted EBITDA margins – Adjusted EBITDA margins are Adjusted EBITDA, divided by revenue. There is no similar financial measure in our financial statements with which to compare. Adjusted EBITDA is a non-GAAP financial measure. We
believe this measure assists us and readers to compare margins on a percentage basis among our business units.
Total cash unit costs per pound – Total cash unit costs per pound 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.
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.
Net cash unit costs per pound (C1 cash costs per pound) – Net cash unit costs of principal product per pound, 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 site cash cost of sales per tonne – Adjusted site cash cost of sales per tonne for our steelmaking coal operations is defined as the cost of the product as it leaves the mine excluding depreciation and amortization charges, out-bound
transportation costs and any one-time collective agreement charges and inventory write-down provisions.
Net debt to adjusted EBITDA ratio – Net debt to adjusted EBITDA ratio is net debt divided by adjusted EBITDA for the twelve months ended at the reporting period, expressed as the number of times adjusted EBITDA needs to be earned to repay
the net debt.
