Southern Copper's Record Quarter Is a Capital-Allocation Rorschach Test
Record prices and a $0.09 cash cost meet a slipping Tia Maria timeline, negative TC/RCs, and a stock 16% off its August peak.
SCCO · Earnings Call · 2026-10-22
The P&L is not the problem
Southern Copper’s third quarter was, on the face of it, a blowout. Sales rose 39% to $4.7 billion, adjusted EBITDA hit $3 billion and net income reached $1.8 billion, with management noting
we hit record highs for net sales, adjusted EBITDA and net income for the second consecutive quarter
. The metal tape did the heavy lifting: LME copper averaged $6.41 per pound, up 44%; molybdenum rose 36%; silver jumped 59%. Byproduct credits were so strong that the operating cash cost per pound of copper after credits fell to $0.09 from $0.42 a year earlier.
That is not a quarter investors can dismiss. Yet the stock is 16.4% below its Aug. 25 peak of $219.70 and has lost 6.6% over the last 90 trading days. The market is not arguing with the income statement; it is discounting the capital cycle behind it. The last filed quarter showed $4.3 billion of revenue and $1.7 billion of net income, and the shares still trade at 25.9x trailing net income. When a commodity producer prints record numbers and de-rates anyway, the debate is almost always about what management will do with the cash — and what it will cost to keep growing.
A new phrase: negative TC/RCs
The freshest company-specific signal in this call is negative TC/RCs. In prior quarters management talked about low or favorable treatment and refining charges; this time the phrase was explicitly negative, especially in China. The implication is unusual for an integrated producer: concentrate is so tight that smelters are effectively paying a premium for feed. Raul Jacob was blunt about what that does to the long-debated new smelter option: “it's hard to consider building a new smelter with this environment where you get a premium on top of your concentrate copper price” — Raul Jacob, Vice President, Finance, Treasurer and CFO · 2026-10-22. The offset is sulfuric acid, where Southern Copper is long, particularly in Peru.
This is a company-unique twist, not a global keyword wave. It also explains why the old COMEX/tariff arbitrage story has gone quiet. In early 2026 the calls were dominated by U.S. copper tariff risk and the COMEX premium; management repeatedly declined to discuss sales composition. Back then: “we are not making any comments on our sales composition or the impact that this price -- huge price arbitrage...” — Raul Jacob, Executive (likely CFO or IR) - presenting company representative · 2026-01-22. Today, tariffs barely register. The market’s question has moved from “how much premium are you capturing?” to “what is the marginal smelting asset worth in a negative-TC/RC world?” That is a less bullish question, even with copper at $6.41.
Tia Maria slips, and the capex queue gets longer
The project story is where the record quarter starts to crack. Tia Maria, the 120,000-ton-per-year SX-EW project that was supposed to be the next leg of volume growth, is now scheduled to begin operations in the first half of 2028. That is a shift from the prior call, when management said: “For now, we don't expect a delay in the project. That's what we're reporting.” — Raul Jacob, Vice President, Finance, Treasurer and CFO · 2026-07-22 The current explanation is mechanical: “we have found that it will take a little bit longer for us to assemble doing the mechanical assembly of all the equipment” — Raul Jacob, Vice President, Finance, Treasurer and CFO · 2026-10-22. Earlier this year the same project was described as finishing construction in the first half of 2027 and producing about 30,000 tons in the second half: “Construction should be finished by the end of the first half of 2027, and we are expecting to produce about 30,000 tons in the second half of 2027” — Raul Jacob, Vice President, Finance, Treasurer and CFO · 2026-01-28.
Tia Maria is 50% complete, with $884 million invested and $1.1 billion committed. A two-quarter slip is not fatal. But it arrives exactly when the capex queue is lengthening: El Pilar carries a $551 million budget and first production in the second half of 2029; the Cuajone expansion is now framed at $680 million for 55,000 tons of copper and 1,400 tons of molybdenum per year, with a possible 150,000-ton-per-day option. On the prior call, Cuajone was a $600 million-$700 million concept for about 40,000 tons. The scope is bigger, the water question is finally addressed — “we have identified good sources of water for the Cuajone expansion” — Raul Jacob, Vice President, Finance, Treasurer and CFO · 2026-10-22 — but the Board still has to approve it, and capex inflation is under review.
That is the tension in the stock. The last filed quarter showed capex of $423 million, up 79% year over year, and the decade-long program is north of $21 billion. Effective net cash has already moved to negative $664 million. Record prices are funding the growth, but the market is being asked to underwrite a longer, more expensive build with less near-term volume.
The demand story is intact; the tape is tired
Operationally, Southern Copper still has one of the best cost positions in copper. The company expects 918,000 tons of copper in 2026, up 0.7% versus its initial plan, plus 29,000 tons of molybdenum and 24 million ounces of silver. It sees a slight copper surplus in 2026, with global inventories around 1.1 million tons, or roughly 14 days of demand. The long-term demand case — electrification, grids, and AI data center buildouts — remains intact, but the market’s enthusiasm for that theme has cooled recently, and the shares have cooled with it.
The recurring risks are still there. Illegal miners — more than 200 people — remain on the Los Chancas concession, and the project’s 2031 start depends on the Peruvian government clearing them out. A Super El Niño is expected in early 2027; management says southern Peru should see drought, but it has secured water for its operations. Those are known unknowns, not new ones. What is new is the combination: record realized prices, a slipping flagship project, a negative TC/RC regime, and a stock that has already de-rated from its peak. The next catalyst is not the copper price. It is the January call, when Southern Copper is supposed to give firmer 2027 guidance, updated capex, and a final answer on Tia Maria’s cost and schedule. Until then, the record quarter is real — but the market is treating it as a peak-cycle print, not a clear runway.
