Shares of Posco (PKX) surged 5.79% in pre-market trading on Thursday, reflecting a wave of investor enthusiasm following the steel giant's stellar quarterly results and an ambitious new growth roadmap.

The rally was sparked by Posco Holdings' second-quarter earnings report, which significantly exceeded analyst expectations. The company posted earnings per share of 7,785 South Korean won, dramatically higher than the 1,197 won consensus estimate. Revenue also topped forecasts, coming in at 19.259 trillion won compared to the anticipated 17.305 trillion won.

Adding to the positive sentiment, Posco unveiled a mid-term strategy targeting consolidated revenue of 87.9 trillion won by 2028, supported by a 29.1 trillion won investment plan. The blueprint includes expanding overseas steel capacity, growing its lithium business to become a top global supplier, and strengthening its LNG value chain. The company also pledged to return 35% to 40% of adjusted net income to shareholders. The bullish outlook was further reinforced by strong earnings from key subsidiaries, with Posco Future M swinging to a net profit and Posco International reporting a 166% jump in net income, highlighting the group's diversified strength beyond traditional steelmaking.
