SK Inc. said in a regulatory filing on the 28th that its board approved an investment of about 400 billion won to buy SK Ecoplant common shares and convertible preferred shares held by financial investors.
The company said the move is aimed at linking SK Ecoplant’s growth potential in the semiconductor value chain to SK Inc.’s corporate value and maximizing shareholder value. If SK Inc. purchases the common shares and part of the convertible preferred shares, its stake in SK Ecoplant will rise to 71.2% from 66.7%.
Also on the 28th, SK Ecoplant began procedures, including calling an extraordinary shareholders meeting, to buy the remaining convertible preferred shares worth about 650 billion won.
SK Inc. said the decision builds on SK Ecoplant’s business reshuffling led by SK Inc., centered on semiconductor and AI infrastructure. SK Ecoplant has expanded its business model beyond its established EPC business for semiconductor production facilities — engineering, procurement and construction — into the AI data center sector. The company said it aims to strengthen its position as a supplier of AI infrastructure solutions.
SK Ecoplant’s results reflected the shift. On a consolidated basis, 2025 revenue rose 40% to 12.1916 trillion won from 8.7346 trillion won in 2024, and operating profit jumped 40% to 315.9 billion won from 226.1 billion won a year earlier.
SK Inc. said the investment will expand its stake in SK Ecoplant, a key unlisted portfolio company, and accelerate value-up efforts to enhance shareholder value.
An SK Inc. official said the company, as SK Group’s holding firm, will continue to actively rebalance its portfolio around semiconductors, AI infrastructure and energy solutions to raise corporate value.
