The Trough Test
The note · Principal
The note
Teck is the copper company the coal company became. The September 2024 sale of the steelmaking-coal business to Glencore closed a chapter that defined the prior generation of management, and the post-divestiture business is materially cleaner to underwrite. Highland Valley in BC, Quebrada Blanca 2 in Chile, 22.5% of Antamina in Peru, and Carmen de Andacollo. Zinc at Red Dog and Trail. That is the whole story.
The business, in one paragraph
Copper production sits around 480 kt at QB2 full ramp. Highland Valley is a long-life Canadian mine that has been a Teck asset for decades; the mine-life extension capex is the part that determines whether HVC produces into the 2040s or not. Quebrada Blanca 2 was the previous management team's signature decision and a multi-billion dollar capex program; the ramp has been slower than the original schedule and is the question 2026 will answer. Antamina is the cleanest single asset in the portfolio. Red Dog and Trail are a smaller, decent zinc operation that prints reliable cash.
What FY 2025 actually said
Coal divestiture proceeds were returned to shareholders in size during 2024 and 2025 — US$7B-plus across buybacks and special dividends. The capital return policy is 30% of free cash flow as a base, with supplementals tied to balance-sheet position. QB2 throughput continued to ramp; the unit-cost number remained higher than the original case. Highland Valley continues to produce on plan. The zinc segment was stable.
Two things we are reading carefully
1. The QB2 ramp
QB2 is the signature decision of the prior management. The capital was spent. The mine is producing. The ramp to full design throughput at the design unit cost is the part that is still in progress. We do not yet have a confident view on what the steady-state unit cost looks like; the 2026 quarterly data is the dataset that will settle the question.
2. The post-divestiture capital allocation cadence
Returning US$7B of proceeds to shareholders cleanly is the right answer to a divestiture. The harder question is what the post-cash business does with the next dollar of operating cash flow. The 30%-of-FCF base policy is reasonable. The marginal dollar above that policy is where the per-share story is made or unmade.
What we are watching into FY 2026
- QB2 throughput and unit cost at design rate.
- Highland Valley mine-life extension capex.
- Capital return cadence versus any new project capex.
- Zinc segment contribution at Red Dog and Trail.
The coal divestiture cleaned the story. What is left is a copper miner with one open ramp question.
Checklist scorecard
Ten questions, three pillars. Status icons reflect the principal's read on this name; absent a green dot, fall back to the question's standard note. See the full Checklist for the framework.
Pillar I
The business
Does it generate free cash flow through the full cycle, or only the top half of it?
Not yet
FCF through the full cycle is better than the legacy reputation suggests; copper is more cyclical than people remember.
Do the unit economics still work at the worst price of the last decade?
Not yet
Copper at US$3/lb is comfortable; at US$2.50 the marginal mine economics are tighter.
What does the balance sheet look like at trough pricing: net debt, covenants, maturity ladder?
Pass
Post-EVR divestiture the balance sheet is conservative.
When they reinvest a dollar (capex, M&A, or buyback), what actually comes back?
Not yet
QB2 was a multi-billion dollar capex program whose ROIC has been below initial expectations. The ramp will determine the long-term verdict.
Pillar II
The people
How much of the operator's own net worth, bought and not granted, sits in this name?
Not yet
Insider ownership is modest. The Keevil family stake is meaningful but no longer dominant post-2023 dual-class collapse.
What did management actually do in 2015 and 2020: issue, buy back, or sit still?
Not yet
2015: deep stress; equity raised at distressed prices. 2020: dividend held; capital plan reduced. The record is mixed.
Is compensation tied to per-share value, or to production, revenue, and size?
Pass
Compensation is per-share-aligned. The 2023 dual-class collapse improved the governance materially.
Who succeeds the operator, and is that person already visible on the page?
Pass
Succession is visible; Price came from inside, the executive team is named.
Pillar III
The cycle
Where are we on the cost curve that matters: the real one, not the one in the pitch deck?
Not yet
On the global copper cost curve Highland Valley and QB2 sit in the second quartile, not the first. Antamina is more competitive.
What does a “normal” year look like a decade from now, and does this business still work at that price?
Pass
Underwriting at mid-cycle copper of US$3.50–4.00/lb, Teck compounds meaningfully. The thesis works at mid-cycle, not just at peak.

Pillar I. The business. The coal divestiture cleaned the story. Teck is now a copper-and-zinc miner with a meaningful zinc segment at Red Dog and Trail. Highland Valley is a long-life Canadian mine. QB2 is the open question: a multi-billion dollar capex program whose ROIC has trailed initial expectations and whose full ramp will determine the long-term verdict on the prior management's signature decision. Antamina remains the cleanest single asset in the portfolio.
Pillar II. The people. Jonathan Price was promoted from inside in 2022 and led the coal divestiture cleanly. The 2023 dual-class share collapse was a meaningful governance upgrade. Insider ownership is modest. The Keevil family stake is still meaningful but no longer controlling. The capital allocation record on QB2 specifically is the legitimate Pillar II concern; the post-divestiture record is encouragingly per-share-aligned.
Pillar III. The cycle. Copper demand is structurally favourable on the decade-out picture: electrification, grid build, renewable demand. Teck's mines are not first-quartile on the global cost curve but they are durable. Underwriting at mid-cycle US$3.50–4.00/lb copper, Teck produces meaningful free cash. The decade-out question is whether QB2 was a generationally acquired asset or an over-spent one. The answer is in the ramp.
