The call

A shrinking steel business is being propped up by trade barriers and an unproven bet that lithium and overseas mills can replace what China and India have taken.

POSCO Holdings makes steel and is trying to grow into battery materials like lithium. Steel is getting harder to sell because China and India make too much of it too cheaply, and POSCO cannot stop that by itself, unlike a tech company that can lock in customers or a brand people prefer. The company's survival depends on whether its new lithium mines in Australia and Argentina become money-makers, whether trade rules on steel imports stick (Japan and possibly the US may put taxes on Korean steel), and whether the global battery boom actually happens as planned.

Why
01
AI pressure: None apparent. AI is not eating this business directly; AI-driven data center and grid buildouts could add steel demand, not subtract it. Could AI do the core job? Unlikely.
02
Bigger players: Chinese and Indian steel producers. Cheap Chinese and Indian overcapacity has helped push POSCO from the world's 2nd largest steelmaker in 2000 to 8th today. Could a giant copy it? Probably.
03
What protects it. Vertically integrated Korean production base plus trade duties that keep some Chinese steel out of its home market.
What would change this call
Japan finalizes the anti-dumping duty on POSCO galvanized steel (provisional 32.49% as of July 2026). Shows whether POSCO's cost disadvantage in the Japanese market becomes locked in or eases.
US finalizes export tariff rate on Korean steel (reported ~50%). Shows whether POSCO's US market access is structurally impaired.
Argentina and Pilbara lithium operations report sustained quarterly profitability by Q4 2026. Shows whether POSCO's lithium growth bet can replace declining steel margins.
Key numbers
  • 2025 operating profit KRW 1.827T, down 15.7% year over year (2025-12-31)
  • Japan set a 32.49% provisional anti-dumping duty on its steel (2026-07-24)
  • Global steel ranking fell from 2nd to 8th since 2000 (2025-12-31)
Named risks
  • Chinese and Indian overcapacity structurally erodes steel margins and market rank. Severity: high
  • Japan and US tariff rulings (32.49% provisional, ~50% US export tariffs) could restrict exports. Severity: high
  • Lithium ramp remains unproven, with Pilbara losses not yet consistently profitable as of Q1 2026. Severity: medium
  • Planned reduction of stakes in listed subsidiaries could reprice equity and dilute control. Severity: medium

Questions people ask
Is POSCO Holdings profitable in 2026?
Yes but shrinking. FY2025 consolidated sales were KRW 69.095 trillion with operating profit of KRW 1.827 trillion, down 15.7% year over year, and net profit of KRW 504 billion, reported February 3, 2026.
Who is POSCO Holdings' biggest competitor?
Chinese and Indian steelmakers have overtaken POSCO in scale: its global steel ranking slipped from 2nd in 2000 to 8th by 2026, with 37.36 million tons of crude steel produced in 2025, per BusinessKorea data from June 23, 2026.
Could AI replace jobs at POSCO's steel plants?
Yes for plant-floor roles. At Pohang Works, AI vision and sensor systems now run hot metal pretreatment, BOF operation, and secondary refining with humans only approving remotely, an estimated KRW 39 billion annual saving, per a January 18, 2026 report.
Is POSCO's lithium bet working?
Not yet consistently. As of Q1 2026, its Argentina lithium plant ran at about 70% utilization while the Pilbara Lithium Solution project in Australia had narrowing but still unprofitable losses, per POSCO's May 1, 2026 earnings call.
Who owns POSCO Holdings?
It is publicly traded with no controlling parent, listed as KRX:005490 and NYSE:PKX, market cap around KRW 23.7 trillion as of July 25, 2026. In July 2026 management proposed cutting its stakes in listed subsidiaries toward 50%.
What tariffs are hurting POSCO Holdings' steel exports?
Japan imposed a provisional 32.49% anti-dumping duty on POSCO's galvanized steel on July 24, 2026, not yet final, while reports from May 28, 2026 cite roughly 50% US export tariffs on Korean steel under the Trump administration.
