LS Cable & System announced record-breaking profits in 2025, fueled by significant investments in power grid development and a surge in demand related to artificial intelligence (AI) infrastructure.
South Korea’s leading cable manufacturer reported sales of 7.59 trillion won ($5.01 billion) and an operating profit of 279.8 billion won for the past year. This represents a 12.2 percent and 1.9 percent increase, respectively, compared to the previous year. Both figures represent the company’s highest-ever performance.
The company cited the rising demand for high-voltage direct current (HVDC) systems and submarine cables as primary drivers of this growth.
LS Cable’s order backlog reached a record high of 7.63 trillion won by the end of 2025, a 22 percent increase from 2024.
Analysts suggest the company has benefitted from increased investment in power transmission infrastructure as governments and utility companies expand electricity networks to accommodate AI data centers and renewable energy initiatives.
LS Cable’s subsidiaries also reported strong financial results.
Power cable producer LS Eco Energy recorded sales of 960.1 billion won and an operating profit of 66.8 billion won in 2025, marking a 10.5 percent and 49.2 percent increase, respectively. This marks the second consecutive year of double-digit growth for the company.
The company attributed this improvement to growing demand for power infrastructure supporting AI data centers in Southeast Asia and enhanced cross-selling opportunities with LS Cable & Systems in North American and European markets.
LS Marine Solution, specializing in submarine cables, reported sales of 244.2 billion won, up 87.4 percent year-over-year, driven by increased installation work for submarine cables at offshore wind farms.
LS Cable is actively expanding its global manufacturing presence and strengthening its supply chain.
The company is currently constructing a submarine cable plant in the United States and a bus duct plant in Mexico. It is also partnering with Australian rare-earth producer Lynas to secure rare-earth metal supplies.
“With the growing importance of energy security, the value of possessing the capability to execute large-scale infrastructure projects is increasing,” stated an LS Cable official. “We anticipate achieving 10 trillion won in sales by 2030.”
