E1 is an energy company under the LS Group whose core business is the import, storage, transport, and sale of LPG, forming a duopoly in Korea's domestic LPG market together with SK Gas.
The company operates large-scale storage terminals in Yeosu (1.6 million tons per year), Incheon (2 million tons per year), and Daesan (1.1 million tons per year), along with a network of 388 filling stations as of the end of the first quarter of 2026.
LPG accounted for 99.3% of revenue based on first-quarter 2026 sales, with the remainder consisting mainly of leasing and vessel chartering revenue.
Feedstock is procured through long-term supply contracts with Middle Eastern producers such as Saudi Arabia and the United Arab Emirates as well as North American suppliers.
In September 2024, E1 entered power generation by acquiring Pyeongtaek Energy & Power, which operates an 833MW LNG combined-cycle power plant, and it is further expanding this segment through the pending acquisition of Yeosu Green Energy, which holds a 495MW district energy business license.
Subsidiaries include LS Securities, engaged in investment trading and brokerage, and LS Networks, engaged in distribution and leasing, both of which are consolidated into group results.
Overseas, E1 exports LPG to countries including Thailand, China, Taiwan, Japan, and Vietnam, and is pursuing construction of a refrigerated LPG tank terminal in Hai Phong, Vietnam to expand its presence in Southeast Asia.
More recently, the company has launched an integrated fueling station brand called 'E1 Orange Plus' that combines LPG with hydrogen and electric vehicle charging services.
While rival SK Gas has advanced considerably toward LNG, power generation, and global trading, E1 maintains a business structure with comparatively higher reliance on domestic LPG distribution.
