Posco (NYSE:PKX), the Gangnam-Gu, Seoul-based steelmaker, reported a net loss of $155.3 million for the fourth quarter, a sharp reversal from its profitable performance earlier in the year.
On a per-share basis, the company posted a loss of 61 cents.
Revenue for the three-month period stood at $11.62 billion, reflecting the impact of cooling demand in the construction sector and lower average selling prices for carbon steel.
The quarterly deficit dragged down the company's full-year results, though it remained in the black for 2025.
For the fiscal year, Posco reported a total profit of $463.2 million, or $1.43 per share, on consolidated revenue of $48.64 billion.
The performance highlights a significant year-over-year contraction as the industry grapples with overcapacity and high raw material costs.
Despite the near-term losses, Posco is aggressively pivoting its capital toward high-growth verticals.
The company recently confirmed plans to invest $582 million into a joint-venture electric arc furnace mill in Louisiana alongside Hyundai Steel, part of a broader strategy to circumvent U.S. trade barriers and supply the North American automotive market.
Additionally, the company's "Premium Plus" product segment, which includes high-efficiency electrical steel for electric vehicles, remains a core pillar of its 2026 recovery plan.
