Summary

FCX Q1 2026 reported a significant cost beat: actual unit net cash cost was $1.91/lb — far below the $2.60/lb guidance that had been in the wiki from Q4 2025 earnings — driven by strong by-product (gold) credits. However, full-year 2026 copper sales guidance was cut 300M lbs (from 3.4B to 3.08B lbs) and full-year unit cost guidance raised to $1.95/lb (from $1.75) as Grasberg Block Cave restart encounters ongoing material handling bottlenecks. Q2 2026 unit cost guidance is $2.24/lb — still elevated but below the feared $2.60. Copper LME hit $13,380/tonne on May 18, 2026, well above Goldman Sachs' $12,650 full-year average forecast and their $12,000 H2 "fair value." A new supply risk has emerged: a severe sulphuric acid shortage (Hormuz closure + China export ban from May 1) threatens the ~20% of global copper output reliant on hydrometallurgical leaching, which Goldman Sachs flagged as a potential upside risk to their copper price. The ICSG now projects a 150kt deficit in 2026, directly contradicting Goldman's 490kt surplus call — with current market pricing closer to the ICSG view.

Findings

FCX Q1 2026 Results — Cost Beat, Volume Miss

FCX reported Q1 2026 revenue of $6.23B (up from $5.73B YoY), net income attributable to common stock of $881M ($0.61/share), and adjusted EPS of $0.57 — a 21% beat vs. consensus — per search snippets from The Gila Herald Q1 2026 report and Investing.com earnings call transcript.

The key cost surprise: Q1 unit net cash costs came in at $1.91/lb — well below the $2.60/lb guidance that had been provided at Q4 2025 earnings. The beat was attributed to "strong by-product credits," meaning gold output from non-Grasberg operations partially offset the Indonesia volume collapse. However, this is a single-quarter beat driven by gold prices and non-Indonesia operations, not a Grasberg operational recovery. Per TipRanks FCX earnings call summary.

Volume collapse: Indonesia copper sales in Q1 2026: 82M lbs — down from 290M lbs in Q1 2025, a 72% YoY drop. Idle facility and restoration costs: $406M incurred in Q1. Per StockTitan Q1 10-Q filing.

Grasberg Restart: Phased, Bottlenecked, Mid-2027 Full Recovery

The Grasberg Block Cave restart has encountered material handling bottlenecks driven by a 50% increase in wet ore draw points, requiring specialized equipment to regulate ore flow onto automated trains. Remediation work for Production Blocks 2 and 3 was completed; limited mining restarted in March 2026; first equipment unit installed and being tested at Q1 earnings (April 23). Total incremental restart cost: $60–70M. Per Trefis FCX earnings analysis.

• Full-year 2026 copper guidance: 3.08B lbs (cut from 3.4B lbs — 300M lbs reduction)
• Full-year unit cost guidance: $1.95/lb (raised from $1.75/lb)
• Q2 2026 unit cost guidance: $2.24/lb (elevated but below feared $2.60 peak)
• 5-year copper forecast: revised down ~9%; gold ~7%
• Full capacity timeline: mid-2027 (modifications to ore loading infrastructure)
• Operating cash flow guidance 2026: ~$8.7B, assuming copper $6.00/lb and gold $4,500/oz

Copper LME Price — Well Above Sell-Side Models

Copper LME spot: $13,380/tonne on May 18, 2026 (= $6.07/lb). On May 20, 2026 copper was reported at $6.18/lb ($13,630/tonne). Per MacroMicro LME Copper Spot series and TradingEconomics copper commodity page.

Analyst forecasts vs current:

• Goldman Sachs: $12,650/t full-year 2026 average; $12,700 Q2; easing to $12,000 H2 (current price is 12–18% above these levels)
• J.P. Morgan: $12,075/t full-year 2026 average, $12,500/t Q2
• StoneX: $11,490/t full-year 2026 average
• World Bank: ~$9,800/t full-year 2026
• Current market ($13,380–$13,630): rejecting all of the above except the structural-deficit bulls

Market is effectively pricing something closer to the ICSG deficit scenario, not Goldman's surplus model. LME net long positioning is in the 80th percentile — stretched, but not at the top yet. Per metal-sentinel.com weekly outlook.

Goldman Sachs — Maintains 490kt Surplus, Flags Acid Risk

Goldman Sachs (April 6, 2026) raised its 2026 copper surplus estimate to 490,000 tonnes (from 380kt) and cut its full-year average price forecast to $12,650/tonne (from $12,850). Goldman's basis: global refined copper demand growth forecast cut to 1.6% YoY (from 2.0%), primarily because higher energy prices trim ~0.4pp from global GDP. Goldman also forecasts copper to average $12,700 in Q2 before easing to $12,000 H2 "fair value." Per TradingView/Reuters Goldman April 6 note and Kitco April 21 update.

Goldman maintained these forecasts on April 21, 2026 — no revision after the Hormuz-sulphuric acid escalation.

Goldman's own upside risk flag: Goldman specifically noted the Hormuz disruption + China sulphuric acid export ban as a risk that could tighten their surplus scenario. Goldman: "The disruption, combined with China's decision to ban sulphuric acid exports from May 1, could tighten a market critical for copper production." Per BigGo Finance Goldman note.

ICSG — 150kt Deficit in 2026 (Abandoned Surplus Call)

The International Copper Study Group (ICSG) now forecasts a 150,000-tonne refined copper deficit in 2026 — reversing its earlier surplus estimate. The ICSG revised its refined production growth forecast down to 0.9% in 2026 (from higher prior estimates), driven in part by Grasberg's mud-rush disruption. Per The Oregon Group ICSG reporting and AInvest ICSG deficit article.

Goldman (490kt surplus) vs. ICSG (150kt deficit): the gap is 640kt — an extraordinary analyst divergence. Current market pricing at $13,380/tonne is consistent with the deficit view.

Sulphuric Acid — New Supply Constraint for Copper

~20% of global copper production relies on hydrometallurgical leaching, which requires ~2.5 tonnes of sulphuric acid per tonne of copper. Two simultaneous supply shocks:

1. Hormuz closure (since late February 2026): ~50% of global seaborne sulphur trade disrupted; Middle East = ~1/3 of global sulphur supply
2. China sulphuric acid export ban (effective May 1, 2026): 4.6M tonnes/year in 2025 → projected ~1.2M tonnes in 2026; Chile (world's #1 copper producer) sourced ~37% of its acid imports from China

Chilean acid prices rose 44% in one month. Large producers protected by term contracts and inventories; smaller miners facing potential output cuts. The DRC can partially cushion but not replace China's export contribution. Per Discovery Alert acid shortage article, Ecofin Agency, and Mining Weekly May 6.

Wood Mackenzie now identifies sulphuric acid availability as a primary binding constraint, displacing ore grade. Per Crux Investor sulphuric acid analysis.

FCX uses primarily a pyrometallurgical (flotation + smelting) process at Grasberg — not acid-leaching — so FCX is less directly exposed to the acid shortage. The acid risk is concentrated in Chilean/Peruvian SX-EW operations and hydromet projects.

Contradictions and open questions

• Goldman (490kt surplus) vs. ICSG (150kt deficit): 640kt divergence; current $13,380 LME price is rejecting Goldman's model. Goldman has flagged that Hormuz/acid disruption could narrow the surplus — but has not revised their April 6/21 forecasts yet. When Goldman revises, that will be a market event.
• FCX Q1 cost beat ($1.91/lb) vs. $2.60/lb guidance: The beat is real but sourced partly from gold by-product credits at non-Grasberg operations. Q2 2026 guide is $2.24/lb — still elevated. Thesis implication: full cost recovery requires Grasberg Block Cave to ramp, which is now a mid-2027 story, not mid-2026.
• FCX production guidance cut: 3.08B vs. 3.4B lbs (300M lbs cut) is a meaningful volume miss that offsets the cost beat. FCX thesis depends on Grasberg ramping; a 300M lb cut with mid-2027 timeline pushes the earnings recovery.
• Acid shortage impact on FCX: FCX is protected (pyrometallurgical), but SCCO (Chile/Peru, significant SX-EW exposure) faces more direct acid risk — could affect SCCO's cost structure asymmetrically.
• Open question: Goldman's next revision — will the Hormuz acid disruption force a downward surplus revision, and if so, at what price level does Goldman converge to market?
