LS Eco Energy (CEO Lee Sang-ho) has achieved its highest-ever first-quarter financial results. 

The company announced on the 14th that it recorded provisional revenue of KRW 296.4 billion and an operating profit of KRW 20.1 billion for the first quarter of 2026. These represent increases of 29.8% and 31.0%, respectively, compared to KRW 228.3 billion and KRW 15.3 billion for the same period last year. Revenue reached an all-time quarterly high, while operating profit hit a record high for the first quarter. 

Notably, operating profit grew at a faster rate than revenue, demonstrating the company’s sustained commitment to profitability-driven growth. 

LS Eco Energy has broken Q1 revenue records for four consecutive years since recording KRW 176.4 billion in 2023. This represents an average annual growth rate of approximately 19%, and comes alongside record-breaking annual revenues. 

This stellar performance is the direct result of an ongoing transition toward a business structure centered on high-value-added products. Driven by expanding global power grid investments and surging demand from AI data centers, sales of extra-high-voltage cables skyrocketed 177% year-over-year, leading the company's overall growth. 

LS Eco Energy, the sole producer of extra-high-voltage cables in Vietnam, is benefiting directly from the expanded investment in transmission and distribution networks under the Vietnamese government's 8th National Power Development Plan. Increased exports to Europe and power grid projects for ASEAN data centers have further solidified its foundation for growth. 

The improvement in operating profit margin in Q1 was also remarkable, reaching approximately 6.8%, which significantly exceeds the domestic cable industry average of 3% to 4%. This was due to the expanded proportion of high-value products, which translated directly into qualitative improvements in earnings. Even in an industry characterized by high costs, the company successfully boosted its profit margin, confirming the success of its structural enhancements. 

"We are currently pursuing extra-high-voltage cable certification to enter the North American market," said Lee Sang-ho, CEO of LS Eco Energy. "By expanding the optical cable production volume at LSCV, we will proactively respond to the rapid surge in global demand."
