Insights

Equity research analyst

POSCO shows modest revenue decline but a steep profit drop driven by one-off losses.

POSCO HOLDINGS INC. posted 2025 consolidated sales of KRW 69,094,886,193 thousand, down 4.9% from 2024, indicating softer top-line performance. Operating income declined more sharply, falling 15.9% to KRW 1,827,063,211 thousand, showing margin pressure.

The most material change is net income, which decreased from 947,580,322 thousand to KRW 504,403,472 thousand, a 46.8% drop. The company attributes this mainly to a one-time loss in Construction and weak demand in Rechargeable Battery Materials, highlighting sensitivity to construction cycles and battery-material market conditions.

Total assets edged up to KRW 105,192,437,964 thousand and shareholders’ equity to KRW 62,377,691,038 thousand, suggesting the balance sheet remains sizeable despite lower earnings. Because these numbers are preliminary and subject to audit, subsequent audited results will clarify whether any adjustments materially change the profit picture.
