Annual results contracted for four straight years: 2022 revenue of KRW 84.750tn and operating profit of KRW 4.850tn (5.7% margin), 2023 KRW 77.127tn and KRW 3.531tn (4.6%), 2024 KRW 72.688tn and KRW 2.174tn (3.0%), and 2025 KRW 69.095tn and KRW 1.827tn (2.6%).
Net profit attributable to owners fell to KRW 657.7bn in 2025, roughly one-fifth of the KRW 3.144tn earned in 2022, while operating cash flow declined from KRW 6.664tn in 2024 to KRW 4.572tn in 2025.
Quarterly data show Q4 2025 as the inflection point, with revenue of KRW 16.841tn, operating profit of just KRW 12.7bn and a net loss attributable to owners of KRW 225.4bn.
On its earnings call the company attributed roughly KRW 190bn of losses to a POSCO E&C construction halt and bad-debt charges and about KRW 131.9bn to one-off costs tied to the sale of the Zhangjiagang plant in China, adding that these items are not expected to recur in 2026.
Results then improved for two consecutive quarters: Q1 2026 revenue of KRW 17.876tn, operating profit of KRW 706.8bn and net profit to owners of KRW 467.2bn, followed by Q2 2026 revenue of KRW 19.259tn, operating profit of KRW 819.0bn and net profit to owners of KRW 684.8bn.
The quarterly operating margin recovered from about 0.1% in Q4 2025 to roughly 4.0% in Q1 2026 and 4.3% in Q2 2026.
The recovery leans on resources and infrastructure rather than the core mill: battery materials posted KRW 41.0bn of operating profit in Q2 2026, its first profit in nine quarters, while POSCO Pilbara Lithium Solution narrowed its operating loss to about KRW 1.0bn on revenue of KRW 102.0bn.
Over the four quarters from Q3 2025 to Q2 2026, net profit attributable to owners totalled about KRW 1.347tn, already well above the full-year 2025 figure.
The balance sheet was little changed, with 2025 year-end equity of KRW 62.378tn against liabilities of KRW 42.815tn for a debt-to-equity ratio of 68.6%, versus 68.9% in 2022.
