SK Inc., the holding company of SK Group, announced a significant strategic investment of approximately 400 billion won ($271 million) on Tuesday. This move aims to increase its stake in SK Ecoplant, reflecting a strong belief in the construction and engineering arm’s pivotal and expanding role within the group’s critical semiconductor value chain and emerging AI infrastructure ventures.
According to a recent regulatory filing, SK Inc.’s board has officially approved the acquisition of both common shares and a segment of convertible preferred shares in SK Ecoplant, previously held by financial investors. This strategic transaction will substantially increase SK Inc.’s ownership in its key affiliate from 66.7 percent to a commanding 71.2 percent, bolstering its control and strategic alignment.
Concurrently, SK Ecoplant initiated procedures on the same day to convene an extraordinary shareholders’ meeting. This meeting is crucial for advancing its plans to acquire the remaining convertible preferred shares, valued at approximately 650 billion won, further streamlining its capital structure.
SK Inc. underscored that its investment decision is firmly rooted in SK Ecoplant’s proactive portfolio rebalancing strategy. This reorientation is notably driven by its significant expansion into high-growth sectors, specifically semiconductor and artificial intelligence (AI) infrastructure businesses, aligning with SK Group’s future growth engines.
SK Ecoplant has meticulously strengthened its integral position within the SK Group’s comprehensive semiconductor value chain. This robust growth has been achieved through a series of strategic acquisitions and insightful business reorganizations, demonstrating a clear focus on core capabilities.
This strategic expansion saw SK Ecoplant integrate Essencore and SK Airplus in 2024. Building on this momentum, 2025 brought four additional key players in semiconductor materials into its portfolio: SK Trichem, SK Resonac, SK Materials JNC, and SK Materials Performance, cementing its expertise across the supply chain.
Beyond its traditional engineering, procurement, and construction (EPC) expertise for semiconductor production facilities, SK Ecoplant has successfully diversified into high-demand AI data centers. Its expanded business scope now comprehensively covers essential semiconductor materials and sustainable resource circulation, illustrating its broad impact.
This strategic restructuring has demonstrably boosted SK Ecoplant’s financial performance. Last year, the company reported impressive consolidated revenue growth of 40 percent year-on-year, reaching 12.19 trillion won from 8.73 trillion won. Operating profit mirrored this strong trend, surging 40 percent to 315.9 billion won, up from 226.1 billion won in the previous year.
SK Inc. emphasized that this latest investment is pivotal not only for increasing its stake in SK Ecoplant, a key unlisted asset within its portfolio, but also for underpinning its broader ‘value-up’ strategy. The holding company anticipates that SK Ecoplant’s escalating importance and expanded capabilities within the group’s dynamic semiconductor value chain will directly and significantly contribute to SK Inc.’s overall valuation and long-term synergistic growth.
An official from SK Inc. reiterated the company’s forward-looking strategy, stating, “As SK Group’s holding company, we remain committed to continuously rebalancing our portfolio. Our strategic focus will be firmly placed on high-growth areas such as semiconductors, AI infrastructure, and advanced energy solutions, all aimed at robustly enhancing overall corporate value for our stakeholders.”
