Teck Resources Ltd Class B (TECK)

Q3 2026

Teck's copper growth and Anglo merger advance, but tariff doubt jolts the sector

  • Anglo American clears coal sale ahead of Teck merger Anglo American agreed to sell its Australian steelmaking coal assets for up to $3.88 billion, simplifying its portfolio and cutting debt before combining with Teck. The merged company would be over 70% copper, tying Teck more directly to electrification and AI power demand.

    This deal removes a hurdle to the merger and sharpens Teck's copper focus, supporting the stock.

  • Teck mails merger election forms to shareholders Teck sent letters of transmittal to registered shareholders for its court-approved merger with Anglo American. Each Teck share converts to 1.3301 Anglo American shares. The election window is open, and shareholders must act before the deadline to receive consideration.

    This is a concrete step toward completing the merger, reducing uncertainty and supporting Teck's price.

  • Canada backs Teck's Trail critical minerals expansion Canada launched its Critical Minerals Accelerator with Teck's Trail Operations as the first deal. The Canada Growth Fund will invest up to $400 million, with total potential investment up to $850 million to double germanium and antimony output and possibly add gallium. This boosts Teck's growth prospects.

    Government funding and streamlined regulation for a new critical minerals project add value and reduce risk for Teck.

  • Record copper prices drive Q2 earnings surge Teck reported $2.2 billion adjusted EBITDA for Q2 2026, up 204% from last year, as record copper prices and 25% higher production lifted results. Adjusted profit was $1.93 per share. The Anglo American merger remains on track for closing within the original timeline.

    Strong earnings show Teck's core business is thriving and the merger is progressing, both positive for the stock.

  • Anglo Teck leadership named, synergies targeted Teck and Anglo American announced the future executive team for Anglo Teck, with Duncan Wanblad as CEO and Jonathan Price as deputy. The combined company, headquartered in Vancouver, targets about $800 million in annual pre-tax synergies by year four, plus revenue gains from optimizing Chilean copper mines.

    Naming leadership and quantifying synergies makes the merger's benefits more concrete, supporting Teck's valuation.

  • Copper tariff doubt triggers sharp sector selloff Copper mining stocks fell sharply after reports cast doubt on White House tariffs for refined copper. Teck slid 7% to $65.08, and benchmark copper dropped 3.1% from a record high. Despite the drop, Teck remains up 36% year to date.

    This is a fresh negative shock that directly hit Teck's price and highlights a key risk for copper producers.
