Merger and restructuring
LOTTE Chemical will spin off its Daesan plant and absorb the new entity into HD Hyundai Chemical via an absorption merger after a June 2026 contract, targeting completion by September 2026; LOTTE Chemical and HD Hyundai Oilbank will each hold 50% and contribute KRW 600 billion to the integrated corporation. The move aims to strengthen vertical integration from feedstock to final products and improve cost competitiveness. A separate restructuring plan for the Yeosu industrial complex was submitted in December 2025, with a detailed plan filed March 20 to adjust overlapping facilities with Hanwha Solutions, DL Chemical and Yeochun NCC.
Specialty materials and capacity
LOTTE targets over 60% of sales from specialty materials by 2030. LOTTE Engineering Plastics is building a 500,000 t/yr compounding plant in Yulchon, Jeonnam, with some lines already commercial and full commissioning scheduled for H2 2026; the plant will supply customized high‑performance materials and is planned to produce Super EP for Physical AI, aviation and aerospace.
Hydrogen value chain
LOTTE SK Eneroot began commercial operation of a 20MW hydrogen fuel‑cell plant in Ulsan in June 2025 and plans three more fuel‑cell plants to reach 80MW by end‑2026. LOTTE Air‑Liquide Ener’Hy opened Korea’s largest 450‑bar high‑pressure hydrogen shipment center in Daesan in November 2025, with production equivalent to roughly 4,200 passenger cars or 1,100 commercial buses per day.
Key materials and semiconductor supply
LOTTE Energy Materials is expanding supply of high‑end copper foil and AI circuit foil from Korea’s circuit foil base. Hantok Chemicals, a JV with Tokuyama, is expanding TMAH (semiconductor developer) capacity and plans a ~9,800 pyeong developer facility in Pyeongtaek.
