Antofagasta Reports 60% EBITDA Jump and Dividend Surge in H1 2025 Results

Antofagasta Delivers a Copper-Fuelled Masterclass

Antofagasta’s H1 2025 results aren’t just good – they’re the kind of numbers that make you sit up and recalculate your portfolio allocations. This isn’t merely beating expectations; it’s a demonstration of operational excellence meeting favourable market dynamics head-on. CEO Iván Arriagada’s confidence isn’t misplaced – it’s backed by a 60% surge in EBITDA and margins hitting levels not seen since 2021. Let’s crack open these results.

The Financial Engine: Powering Ahead

The headline figures tell a compelling story:

• Revenue Up 29%: $3.8bn (H1 2024: $3.0bn), fuelled by higher copper sales volumes (+17%) and robust gold sales (+53%).
• EBITDA Soars 60%: $2.23bn (H1 2024: $1.39bn) – a staggering jump reflecting both top-line growth and impressive cost discipline.
• Margin Expansion: EBITDA margin surged 12 percentage points to 58.8%, placing Antofagasta firmly at the top end of global pure-play copper producers.
• EPS Doubles: Underlying EPS hit 47.4 cents, up 112% year-on-year.
• Dividend Surge: The interim dividend more than doubled to 16.6 cents per share (+110%), maintaining a 35% payout ratio of underlying earnings.

This performance wasn’t luck. It was built on operational grit: higher production, materially lower costs, and the relentless execution of their Competitiveness Programme, which delivered $60m in H1 savings (targeting $100m for the full year).

Operational Muscle: Where the Magic Happened

Drilling down (pun intended), the operational execution was exceptional:

• Copper Production Up 11%: 314,900 tonnes, driven by Los Pelambres and Centinela Concentrates.
• Cost Crunch: Cash costs before by-product credits fell 12% to $2.32/lb. Net cash costs plummeted 32% to $1.32/lb – a remarkable achievement given inflationary pressures elsewhere in the sector.
• By-Product Bonanza: Gold production jumped 36% (91,200 oz), and Molybdenum rose 42% (7,400 tonnes), significantly boosting credits.
• Balance Sheet Strength: Net debt/EBITDA remains comfortable at 0.54x (up slightly from 0.46x at H1 2024, reflecting planned growth capex). Cash flow from operations grew 22% to $1.8bn.

Asset Spotlight: Centinela & Los Pelambres Shine

• Centinela: Was the star performer. EBITDA rocketed 184% to $938m. Copper production surged 25%, with copper-in-concentrate leaping 84%. Net cash costs halved to $1.00/lb.
• Los Pelambres: Solid 22% EBITDA growth to $1,078m. Copper (+8%), Gold (+37%), and Moly (+36%) production all increased. Net cash costs fell 15% to $1.03/lb.

Growth Pipeline: Building the Future

Antofagasta isn’t resting. Its medium-term +30% copper output growth thesis is underpinned by major projects:

• Centinela Second Concentrator ($4.4bn): Full construction underway, now in its second year. A November 2025 site visit will showcase progress. This is the cornerstone of future volume growth.
• Los Pelambres Expansion ($2bn est.): Desalination plant expansion and new concentrate pipeline/El Mauro enclosures progressing on schedule (2027 completion). EIA submitted for the Development Options Project (mine life to 2051, potential throughput increase).
• Zaldívar Extension: Critical EIA approved in May 2025, securing mine life to 2051 and enabling the water transition plan.

Capital expenditure hit $1.62bn in H1 (guided $3.9bn for FY2025), signalling the acceleration of investment in this growth.

Dividends & Discipline: Rewarding Shareholders

The 110% dividend increase to 16.6 cents per share isn’t just a flashy headline. It’s a direct result of the 35% payout policy embedded within Antofagasta’s disciplined capital allocation framework. This balance – rewarding shareholders while fully funding essential growth – is a hallmark of management’s confidence and strategic clarity. Expect the final dividend to potentially include any excess cash distribution as per policy.

Sustainability & Innovation: Not Just Box-Ticking

Beyond the numbers, the report highlights genuine progress:

• Safety: Another fatality-free period. High-potential incident rate improved significantly.
• Tailings: Achieved full compliance with the Global Industry Standard on Tailings Management (GISTM) at key facilities.
• Water: 63% of Group water withdrawals came from seawater in H1. Zaldívar’s EIA approval includes a structured transition away from continental water.
• Decarbonisation: Piloting trolley-assist haulage, fuel efficiency programs, and testing Chile’s first green hydrogen-powered locomotive in the Transport division.
• Diversity: Female workforce representation reached 26.7% (up from 8.8% in 2018), targeting 30% by end-2025.

Outlook: Copper’s Structural Tailwinds Intact

Management reaffirmed 2025 guidance:

• Copper Production: 660,000 – 700,000 tonnes.
• Cash Costs: $2.25-2.45/lb (before by-products), $1.45-1.65/lb (after by-products).
• Capex: $3.9 billion.

The narrative around copper remains powerfully supportive: energy security, decarbonisation, AI, and infrastructure demand, coupled with persistent supply challenges (grade decline, disruptions). Antofagasta, with its top-tier margins, disciplined growth execution, and commitment to shareholder returns, looks exceptionally well-positioned to ride this wave.

The Takeaway: Pure-Play Powerhouse

Antofagasta’s H1 2025 is a textbook example of a well-run miner firing on all cylinders. Stellar financials, operational delivery, visible growth, and shareholder rewards – it ticks every box. The 60% EBITDA leap and dividend surge are more than just results; they’re a statement of intent. For investors seeking copper exposure with quality, growth, and yield, Antofagasta deserves a very close look. The market’s reaction will be fascinating, but the fundamentals speak loudly enough.
