Teck Lowers Copper Cost Outlook as Net Cash Rises

Teck Resources (NYSE: TECK) reported C$2.305 billion in third-quarter adjusted EBITDA, up 97% from a year earlier, in its unaudited results dated October 28, 2026. Teck produces copper and zinc, and attributed the increase primarily to higher metal prices, higher by-product revenues and lower smelter processing charges. For those of us holding the shares, the stronger quarter brings more cash and a lower annual copper cost outlook, with operating disruptions still testing production.

The cash gives us a clearer measure of what reached the balance sheet. Teck's October 28 release reports C$1.6 billion in operating cash flow for the quarter and a C$655 million increase in its net cash position, a non-GAAP measure. It held C$6.7 billion in cash at September 30. That gives the business more financial room while it deals with disrupted operations. We should still judge future cash generation against the metal prices and operating conditions that produced this quarter's result, because a strong completed quarter cannot guarantee the next one.

The guidance change gives you something more useful than a backward-looking earnings comparison. In the same October 28 results, Teck lowered its annual copper net cash unit cost guidance because of strong by-product pricing so far this year. Quarterly copper net cash unit costs fell to US$1.77 per pound from US$2.09 a year earlier. This is also a non-GAAP measure, and the company's explanation ties part of the improvement to prices received for other metals. How much of that benefit can carry forward? We would want continued cost performance alongside supportive by-product prices before assuming the stronger margins will persist.

Production at Quebrada Blanca, or QB, shows why the operating test remains open. Teck's October 28 account says the mine produced 47,200 tonnes of copper in the third quarter, down from 55,800 tonnes in the second. Severe weather caused power outages and equipment shutdowns, while wet mining conditions restricted access to planned higher-grade ore. Teck expects additional mining faces to improve flexibility through the fourth quarter and into next year. For your shares, that offers a route to more reliable production, but the expected improvement still has to appear in operating results.

We covered the separate labour risk in Teck Reports Highland Valley Strike and Reduced Operations. These earnings give us stronger financial results to assess alongside that disruption; they do not establish its eventual cost. Adjusted EBITDA is a non-GAAP earnings measure, and you cannot use its increase as an estimate of cash available after every investment requirement. Our focus stays on whether Teck can sustain cash generation while improving operating reliability. A lower cost outlook helps holders most when the company can also produce and sell the copper behind it.

Our year-end 2026 checkpoint is QB's operating progress and a Highland Valley update quantifying the strike's effect on output and costs.
