Global Electrification Will Drive Copper Demand With Centinela And Pelambres

Key Takeaways

• Rising copper demand and innovative extraction methods could significantly boost Antofagasta's revenue, production growth, and profit margins beyond current expectations.
  
• Expansion projects, operational partnerships, and strong ESG practices may drive cost savings, enhanced efficiency, and sustained premium market positioning.
  
• Rising capital demands, reliance on ageing water-intensive Chilean assets, and mounting regulatory and environmental pressures threaten Antofagasta's long-term profitability and earnings stability.

Catalysts

Operates as a mining company.

• While analyst consensus acknowledges robust copper demand from electrification and supply constraints, they may be underestimating the structural deficit as new global copper discoveries stagnate, creating the potential for copper prices to reach and persist at far higher levels, which could significantly enhance Antofagasta's revenue and margins.
  
• Analysts broadly agree on the positive impact of the Centinela and Los Pelambres expansions, but production upgrades could exceed guidance if grades at Los Pelambres revert to historic highs and if project ramp-ups continue ahead of schedule, driving outsized earnings growth in the medium term.
  
• Antofagasta's first-mover advantage in developing and deploying proprietary innovations like Cuprochlor for primary ore recovery positions it to extract value from assets previously considered submarginal, unlocking substantial future production growth and margin expansion not currently factored into consensus forecasts.
  
• The company's increasing operational collaboration with major neighbors, particularly at Zaldívar and Escondida, could yield large-scale cost savings, shared infrastructure benefits, and improved ore access, materially lowering per-unit costs and strengthening long-term profitability.
  
• As global sustainability mandates tighten, Antofagasta's leadership in water solutions and ESG practices stands to secure premium pricing with green-conscious consumers and investors, stabilizing revenues and supporting elevated EBITDA margins well above peers.

Antofagasta Future Earnings and Revenue Growth

Assumptions

• This narrative explores a more optimistic perspective on Antofagasta compared to the consensus, based on a Fair Value that aligns with the bullish cohort of analysts.
• The bullish analysts are assuming Antofagasta's revenue will grow by 13.4% annually over the next 3 years.
• The bullish analysts assume that profit margins will increase from 14.6% today to 16.1% in 3 years time.
• The bullish analysts expect earnings to reach $1.8 billion (and earnings per share of $1.77) by about August 2028, up from $1.1 billion today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the price target of the more bullish analyst cohort, the company would need to trade at a PE ratio of 24.0x on those 2028 earnings, down from 25.8x today. This future PE is greater than the current PE for the GB Metals and Mining industry at 10.1x.
• Analysts expect the number of shares outstanding to remain consistent over the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.97%, as per the Simply Wall St company report.

Antofagasta Future Earnings Per Share Growth

Risks

• Antofagasta's expansion plans and ongoing projects, such as Centinela and Pelambres, demand substantial capital expenditures and depend on timely execution; delays, cost overruns, or the need for significant future investments-especially for water solutions at Zaldívar-could erode free cash flow and compress net margins in the long term.
  
• The company remains heavily reliant on water-intensive, ageing Chilean assets, notably Los Pelambres and Zaldívar, which makes it vulnerable to escalating water scarcity and higher operating expenses; these pressures could disrupt production and reduce net earnings over time.
  
• Heavy dependence on a limited number of large assets, particularly Los Pelambres, means any adverse regulatory, geological, or community event could have an outsized negative effect on overall revenues and earnings stability.
  
• Accelerating global adoption of circular economy practices, copper recycling, and potential advances in alternative materials may structurally reduce long-term demand growth for primary mined copper, undermining Antofagasta's pricing power and putting pressure on topline revenue.
  
• Intensifying regulatory requirements and ESG scrutiny, particularly concerning environmental impact and water usage in Chile, are likely to drive up compliance costs and potentially threaten Antofagasta's license to operate, posing sustained risks to net margins and profitability.

Valuation

• The assumed bullish price target for Antofagasta is £25.14, which is the highest price target estimate amongst analysts. This valuation is based on what can be assumed as the expectations of Antofagasta's future earnings growth, profit margins and other risk factors from analysts on the bullish end of the spectrum.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of £25.14, and the most bearish reporting a price target of just £12.92.
• In order for you to agree with the bullish analysts, you'd need to believe that by 2028, revenues will be $10.9 billion, earnings will come to $1.8 billion, and it would be trading on a PE ratio of 24.0x, assuming you use a discount rate of 8.0%.
• Given the current share price of £21.16, the bullish analyst price target of £25.14 is 15.8% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
