Glencore (LSE: GLEN), the FTSE 100 mining giant, has seen its share price rise more than 100% in a year, yet still trades on a price-to-earnings ratio of 261.
At first glance, that valuation looks difficult to justify, particularly with profits collapsing to just $120m last year.
However, mining stocks are rarely valued purely on recent earnings, with investors instead tending to look forward at longer-term structural opportunities.
At a recent capital markets day, Glencore’s management outlined a more ambitious copper strategy, targeting annual production growth from around 850,000 tonnes today to 1.6 million tonnes by 2035.
If achieved, that target would position Glencore as the world’s largest copper producer, a significant shift in the company’s scale and market standing.
The company has historically been cautious about bringing major new supply online, preferring sustained price strength over short-lived commodity spikes.
Copper prices have risen more than 70% since early 2024, driven by several converging long-term demand trends including electrification, grid expansion, data infrastructure and industrial investment.
Yet supply is struggling to keep pace, with existing mines ageing, new discoveries harder to develop, and large projects taking well over a decade to reach production.
Even with announced developments, forecast supply still appears well short of expected demand over the coming decades, creating conditions that could require sustained higher prices to encourage new production.
For companies with existing resources and expansion options already in place, that structural backdrop could prove increasingly valuable over time.
The most immediate risk for investors is timing, as large-scale supply responses depend on successful execution across multiple jurisdictions and can take years to deliver.
Permitting delays, capital allocation challenges, or project ramp-up setbacks could all slow Glencore’s path toward its higher production targets.
There is also the possibility that commodity prices do not cooperate, with volatility remaining high even in a structural deficit environment, potentially compressing returns or delaying investment decisions.
Operational delivery presents a further challenge, with growth spread across multiple regions increasing complexity and raising the potential for cost overruns or disruption at key assets.
The market may still be underestimating how far copper dynamics could run if structural deficits persist, leaving Glencore positioned as a leveraged way to access that theme through scale and optionality.
