Teck Resources Ltd

Continued growth in copper production and over $1.3 billion returned to shareholders this year

VANCOUVER, British Columbia, Oct. 24, 2024 (GLOBE NEWSWIRE) — Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (Teck) today announced its unaudited third quarter results for 2024.

"The third quarter marked a new era for Teck as we successfully transformed into a pure-play energy transition metals company with leading copper growth," said Jonathan Price, President and CEO. "We closed the sale of our remaining interest in the steelmaking coal business and have returned over $1.3 billion to shareholders so far this year, while also reducing debt and ramping-up copper production."

Highlights

• Adjusted EBITDA1 of $986 million in Q3 2024 was driven by record copper production as Quebrada Blanca (QB) continues to ramp-up operations, as well as strong base metals pricing and zinc sales volumes from Red Dog. Our loss from continuing operations before taxes was $759 million in Q3 2024, primarily due to an impairment charge at our Trail Operations.

• Adjusted profit from continuing operations attributable to shareholders1 was $314 million, or $0.61 per share, in Q3 2024. Our loss from continuing operations attributable to shareholders was $748 million, $1.45 per share, in Q3 2024, primarily due to an impairment charge at our Trail Operations.

• We completed the sale of the remaining 77% interest in our steelmaking coal business, Elk Valley Resources (EVR) and received cash proceeds of US$7.3 billion on July 11, 2024. We commenced deployment of these proceeds through shareholder returns and debt reductions in Q3.

• We returned a total of $720 million to shareholders in the third quarter through the purchase of $398 million of Class B subordinate voting shares pursuant to our normal course issuer bid, and $322 million in dividends, reflecting our regular base quarterly dividend and a supplemental dividend of $0.50 per share, or $257 million.

• From January 1 to October 23, 2024, we have returned over $1.3 billion to shareholders through share buybacks and dividends.

• We reduced our debt by US$1.5 billion through a bond tender offer for our public notes in July and the repayment of short-term loans at Carmen de Andacollo.

• Our liquidity as at October 23, 2024 is $11.9 billion, including $7.8 billion of cash. We generated cash flows from operations of $134 million in Q3 and had a net cash position of $1.8 billion at September 30, 2024.

• We achieved another consecutive record quarter of copper production with 114,500 tonnes in the third quarter, of which 52,500 tonnes were from QB. Production at QB continues to ramp-up and we expect to be operating at full throughput rates by the end of 2024.

• Copper prices (LME) remain strong, averaging US$4.18 per pound in the third quarter and closing the quarter at US$4.43 per pound, contributing to $103 million of positive pricing adjustments in the third quarter.

• Red Dog's performance was strong in the third quarter with zinc production increasing by 14% to 142,500 tonnes compared to the same period last year. Red Dog's zinc net cash unit costs1 have improved and our 2024 annual unit cost guidance for zinc has been updated accordingly.

Key Updates

Executing on Our Copper Growth Strategy

• QB copper production of 52,500 tonnes in the third quarter increased compared to 51,300 tonnes in the second quarter of 2024, as quarter over quarter production ramp-up continues.

• Mill throughput rates increased quarter over quarter confirming plant design is robust. We continue to expect to be at design mill throughput rates by the end of 2024.

• The localized geotechnical issue identified and disclosed in Q2 2024 has now stabilized with controls in place and we are advancing the mine plan.

• Grades in Q3 were lower, consistent with our previously disclosed guidance, and we continue to expect higher grades in Q4. Normal grade variability is expected within any given period, as considered in our mine plans.

• Based on current production levels and expected throughput and recoveries, the upper end of our 2024 annual QB copper production guidance range has been updated and our guidance range is now 200,000 to 210,000 tonnes. In addition, as a result of our lower than expected molybdenum production levels, we have updated our previously disclosed annual QB molybdenum production guidance to 0.8 to 1.2 thousand tonnes.

• We continue to expect QB's total and net cash unit costs1 for 2024 to be within our previously disclosed guidance, despite the reduction in annual molybdenum production guidance.

• Due to the ongoing work to improve copper recovery and equipment reliability extending into the first half of 2025, we have updated our previously disclosed 2025 QB annual copper production guidance to 240,000 to 280,000 tonnes and molybdenum production to 4.0 to 5.5 thousand tonnes.

• Mill optimization work to push performance past nameplate by improving throughput is currently underway with plans for debottlenecking efforts being advanced.

• In the third quarter, we continued to make progress in advancing Teck’s copper growth strategy, reinforcing our commitment to long-term value creation through a balanced approach of growth investments and shareholder returns. While maintaining a strong balance sheet, Teck’s prudent investment plans are designed to de-risk the development of our assets, including navigating the permitting process. As previously disclosed, Teck does not anticipate sanctioning any growth projects in 2024. The focus remains on advancing our near-term projects for potential sanctioning in 2025. All growth projects must meet stringent criteria, delivering attractive risk-adjusted returns and competing for capital in alignment with Teck’s capital allocation framework.

New Business Structure to Support Transition to Pure-Play Energy Transition Metals Company

• In August, we announced a new business structure to support our shift to a pure-play energy transition metals company focused on growth. The new business structure organizes Teck around two regional business units for North America and Latin America (LATAM), and a dedicated Projects group to develop and execute brownfield and greenfield projects.

• This structure simplifies Teck with a streamlined executive leadership team and regional structure to deliver on our strategy of copper growth balanced with shareholder returns and long-term resiliency. It positions Teck to drive improved operational performance, while efficiently and responsibly capitalizing on profitable growth opportunities to enhance value for all stakeholders.

• Our reported segmented financial results and summary information contained in our Management Discussion and Analysis will continue to be disclosed on a commodity basis for our copper and zinc operations in addition to our corporate segment.

Deployment of Transaction Proceeds from Sale of Steelmaking Coal Business

• We completed the sale of our remaining 77% interest in our steelmaking coal business, EVR, to Glencore and received transaction proceeds of US$7.3 billion on July 11, 2024.

• On closing of the transaction, we announced our intention to allocate the transaction proceeds consistent with Teck's Capital Allocation Framework. This included the repurchase of up to $2.75 billion of Class B subordinate voting shares, a one-time supplemental dividend of $0.50 per share, a debt reduction program of up to $2.75 billion, funding retained for our value-accretive copper growth projects, and approximately $1.0 billion for final taxes and transaction costs.

• Combined with the $500 million share buyback announced in February, total cash returns to shareholders of $3.5 billion from the sale of the steelmaking coal business have been authorized.

• In Q3, we commenced deployment of the proceeds through shareholder returns and debt reduction. We returned a total of $720 million to shareholders in the third quarter through the purchase of $398 million of Class B subordinate voting shares pursuant to our normal course issuer bid, and $322 million in dividends, reflecting our regular base quarterly dividend and a supplemental dividend of $0.50 per share, or $257 million. We reduced our debt by US$1.5 billion through a bond tender offer for our public notes in July and the repayment of short-term loans at Carmen de Andacollo.

• From January 1 to October 23, 2024, we have returned over $1.3 billion to shareholders through share buybacks and dividends.

• In our third quarter News Release, Management's Discussion and Analysis, and Condensed Interim Consolidated Financial Statements, EVR's results have been presented as discontinued operations for all periods reported.

Safety and Sustainability Leadership

• We were saddened to report a fatality on July 24 at the Antamina Mine, our joint venture with BHP, Glencore and Mitsubishi. Antamina has conducted a full investigation and learnings will be shared across our company and industry.

• We continued to focus on driving health and safety at our sites, with our High-Potential Incident (HPI) Frequency rate remaining steady at 0.10 in Q3 2024, a 33% reduction compared to the same period last year.

• On October 9, 2024, Teck was named to the Forbes list of the World’s Best Employers 2024, an employee-driven ranking of multinational companies and institutions from over 50 countries around the world.

Guidance

• We have updated our previously disclosed 2024 annual guidance for zinc net cash unit costs1, and copper, molybdenum and refined zinc production. The remainder of our previously disclosed guidance for 2024 is unchanged. We have updated our previously disclosed 2025 annual copper and molybdenum production guidance for QB, as outlined above.

• Continued strong performance at Red Dog has resulted in an improvement in net cash unit costs1 and accordingly, our 2024 annual zinc net cash unit costs1 are now expected to be US$0.45 to $0.55 per pound, compared to our previously disclosed guidance range of US$0.55 to $0.65 per pound.

• Our 2024 annual copper production guidance has been updated to a range of 420,000 to 455,000 tonnes, a reduction from our previously disclosed guidance of 435,000 to 500,000 tonnes. The reduction relates to Highland Valley Copper, as well as a reduction to the upper end of QB's production guidance range. Highland Valley Copper's guidance reduction was a result of a delay in mining in the Lornex pit due to challenges with labour availability and the autonomous systems of our new haul trucks. This has been largely resolved and we expect to process more ore from the Lornex pit in the fourth quarter.

• Molybdenum production for 2024 has been reduced by 1.3 to 1.5 thousand tonnes to 3.0 to 4.0 thousand tonnes due to lower production at Highland Valley Copper and QB.

• Refined zinc production at Trail for 2024 has been reduced to a range of 240,000 to 250,000 tonnes as a result of a localized fire in the electrolytic zinc plant on September 24, 2024.

• Our guidance is outlined in summary below and our usual guidance tables, including three-year production guidance, can be found on pages 26–29 of Teck’s third quarter results for 2024 at the link below.

USE OF NON-GAAP FINANCIAL MEASURES AND RATIOS

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 from continuing operations attributable 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 per share from 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 per share from 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.

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.

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 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. QB2 costs and ramp-up are dependent on, among other matters, our continued ability to advance ramp-up as currently anticipated. Production at our 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.
