Capstone Copper's Soft Target Gives Way to a Record Price Rebound
A disappointing mid-term production target sparked a sharp sell-off, before record copper prices and beaten expectations restored the structural growth story.

In short
Capstone Copper fell 30-45% from January 2026 record highs after a disappointing mid-term CY27 production target came in around 10% below expectations, compounded by falling copper prices.
The stock rebounded strongly as copper prices hit record and then all-time highs, with a first-quarter result showing record group EBITDA of $329 million, beating expectations by 10%.
Fund managers including Yarra Capital Management and Milford Asset Management see Capstone as a preferred pure-play route to structural copper demand from EVs, data centres and electrification, with production potentially nearly doubling by decade's end.
Capstone Copper delivered a genuinely violent 2026, falling 30 to 45 percent from January's record highs on a disappointing mid-term production target and softer copper prices, before rebounding strongly as record copper prices and record quarterly EBITDA restored fund managers' conviction in its structural growth story.
A disappointing target overshadows a strong long-term story
PM Capital said the stock fell 30 percent after reaching record highs in January, though its long-term thesis remains intact, tied to structural supply constraints and accelerating demand from AI data centres and electric vehicles, and separately said it increased its holding following an intra-quarter peak-to-trough decline of 45 percent, with the position a meaningful contributor to performance since initiating in April 2025. Ellerston Capital said Capstone had previously provided CY26 guidance of 200,000 to 230,000 tonnes of copper production at US$2.45 to US$2.75 a pound, but gave a mid-term CY27 target of around 265,000 tonnes for the first time, around 10 percent below expectations, underwhelming shareholders just as an 8 percent fall in the copper price made things worse. Perennial Partners said the stock fell 29.8 percent in March as rising risks to global growth weighed on industrial metals demand, with the bellwether copper price down 9.5 percent. Yarra Capital Management, overweight, said the stock underperformed as copper prices declined 2 percent on Iran war-related impacts, with medium-term production commentary soft relative to expectations, though it maintained a positive view. Katana Asset Management called Capstone its preferred copper exposure on the ASX with the best organic growth profile among listed copper names, despite a disappointing first-quarter operational update, remaining attracted to the long-term market deficit and Capstone's long-term growth profile.
CSC gave a mid-term (CY27) target of ~265kt for the first time. This target was ~10% below expectations and underwhelmed shareholders. The 8% fall in the copper price made things even worse.

A rebound built on record prices and beating expectations
Hyperion Asset Management said it began taking allocation to materials businesses including Capstone alongside BHP, Rio Tinto and ALS. Pendal Group said a first-quarter result came in solid, with production in line and costs beating on higher silver by-product credits at the Cozamin mine, group EBITDA beating by 10 percent to a record $329 million, spurred by record copper prices. PM Capital said the stock rose 30 percent on robust copper demand, remaining central to its thesis on the structural necessity of critical minerals in the global energy transition, and took the opportunity to realise some profits following the strong rebound. Yarra Capital Management said the stock outperformed in May as copper prices rose 6 percent to close at US$6.26 a pound on continued strong demand led by EVs and data centres, maintaining a positive view given Capstone's pure-play leverage to copper markets and potential to nearly double production by decade's end. Milford Asset Management named Capstone one of its preferred long-term commodity exposures given copper's role in electrification, grid investment and data centres.
We maintain a positive view on CSC due to its pure-play leverage to attractive copper markets coupled with the potential to nearly double production by decade's end.

August: an all-time high prompts profit-taking
PM Capital said the stock rose 19 percent as copper hit an all-time high, and with valuations now reflecting the higher price, the fund took profits and trimmed its position.
What fund managers say they are watching next is whether copper prices hold near all-time highs, delivery on the roadmap to nearly double production by decade's end, resolution of the mid-term production target concerns that triggered the March sell-off, and whether the structural EV and data centre demand thesis continues supporting the valuation now that several managers are trimming into strength.
