Teck Resources (TECK) Q4 2025 earnings review
Copper Prices and Merger Momentum Mask Zinc Decline
Teck closed 2025 with a financial surge, driving Adjusted EBITDA up 81% YoY to $1.5B, largely thanks to realized copper prices averaging over $5.00/lb. While the Quebrada Blanca (QB) mine is recovering from Q3 lows, the real story is the pending 'Anglo Teck' merger and the stark divergence in commodity production: Copper is growing, but Zinc production is collapsing as Red Dog grades deteriorate. Management has paused buybacks pending the merger close, leaving dividends as the sole yield vehicle.
🐂 Bull Case
Teck realized $5.11/lb for copper in Q4 (+23% YoY). With global smelting capacity shortages and high demand, Teck's pure-play leverage to copper is timing the market perfectly.
Approvals are progressing (ICA received). The merger promises $800M in synergies and a potential $1.4B EBITDA uplift from the QB/Collahuasi adjacency, creating a top-5 global copper producer.
🐻 Bear Case
The decline at Red Dog is severe. 2026 guidance implies a ~23% drop in zinc concentrate production vs 2025. This creates a significant revenue hole that copper volume growth must fill.
Despite Q4 improvement, QB sales lagged production due to weather and shiploader repairs (now resolved). The asset has yet to prove consistent steady-state performance over multiple quarters.
⚖️ Verdict: 🟢
Bullish. Despite the zinc headwinds, Teck is executing well on the items it controls. The surge in profitability driven by copper prices, combined with the imminent merger catalyst, outweighs the Red Dog decline.
Key Themes
Copper Price Realization
The macro environment is doing the heavy lifting. Realized copper prices jumped to $5.11/lb in Q4 from $4.17/lb a year ago. This drove a $295M positive pricing adjustment in the quarter. With net cash unit costs for copper dropping to $1.98/lb (down from $2.09/lb in 24Q4), margins are expanding rapidly (Copper Gross Profit Margin 54%).
Zinc Production Collapse
Decelerating. Red Dog production fell 32% YoY in Q4 (87.3kt vs 128.4kt). 2026 Guidance forecasts a full-year decline of ~23% at the midpoint compared to 2025 actuals (435kt guided vs 565kt actual). Management attributes this to lower grades as the mine nears end-of-life, but it significantly reduces cash flow diversity.
Quebrada Blanca (QB) Recovery
Accelerating. QB copper production bounced back to 55.4kt in Q4 from a low of 39.6kt in Q3, following the resolution of geotechnical issues. While still below the 60.7kt achieved in Q4 2024 due to planned lower grades, the trajectory is positive. Management confirmed the Tailings Management Facility (TMF) development is proceeding to plan to support steady-state.
Inventory Build-up
Copper sales (119kt) lagged production (134kt) in Q4. Management cited weather and sea conditions in December causing a short-term inventory build. While the port facility repairs are complete as of Jan 2026, this timing mismatch deferred cash realization into Q1 2026.
Merger Constraints on Capital Return
While Teck sits on $5.2B in cash and net cash of $150M, share buybacks are suspended ($0 executed in Q4) due to the Anglo American arrangement agreement. Investors receive only the base dividend ($0.125/share) until the deal closes, limiting immediate returns despite record profitability.
Other KPIs
Accelerating. Up 150% YoY from $299M in Q4 2024. This segment now completely dominates the company's profitability profile as Zinc stagnates.
Accelerating. Up significantly from $0.45 in Q4 2024. The beat was driven by operations and pricing, with a slight headwind from FX losses compared to gains in the prior year.
Stable. Includes $5.2B in cash. The company returned to a net cash position ($150M), effectively de-risking the balance sheet ahead of the integration with Anglo American.
Guidance
Stable/Accelerating. The midpoint (492.5kt) implies ~8.5% growth over 2025 actuals (454kt). Growth is driven primarily by QB optimization, offsetting grade declines elsewhere.
Decelerating. The midpoint (435kt) implies a sharp 23% decline from 2025 actuals (565kt). This reflects the structural decline at Red Dog and an updated mine plan at Antamina.
Stable. Midpoint ($2.025) is roughly flat vs 2025 actuals ($2.03). This is positive given inflationary pressures, aided by higher byproduct credits.
Accelerating. A massive step up from $801M in 2025, driven by the sanctioning of the Highland Valley Copper Mine Life Extension (HVC MLE), which alone consumes ~$1B of this budget.
Key Questions
Zinc Gap Strategy
With Red Dog production dropping ~23% in 2026, and the Red Dog Mine Life Extension still in pre-feasibility, how does management plan to plug the cash flow gap from the Zinc segment before the merger closes?
QB Logistics Reliability
With the shiploader repairs complete, are there any lingering risks regarding port availability or weather resilience that could cause inventory builds to persist into Q1/Q2 2026?
HVC MLE Execution
The HVC Mine Life Extension requires ~$1B in capital this year. Given the merger integration planning, are there risks of capital deployment delays or strategic reprioritization of this asset?
