[Alpha Biz= Paul Lee] Seoul, South Korea — Shinsung ST (416180), a specialist in energy storage systems (ESS) and ESS thermal management components, announced on December 3 that it has approved a USD 10 million (approx. KRW 14.7 billion) capital increase for its U.S. subsidiary in Kentucky to secure operating funds and prepare for full-scale production.
The capital injection will be made through the issuance of new shares, increasing the Kentucky subsidiary’s paid-in capital from USD 10 million to USD 20 million.
With this investment, Shinsung ST aims to proactively address the rising demand for liquid-cooling thermal management solutions, which has become a key trend in the North American ESS market, and to secure early operational momentum ahead of mass production scheduled for 2026.
The explosive growth of the AI industry and rapid expansion of data centers have heightened the importance of stable large-scale power supply. As the ESS market—particularly in North America—is expected to grow sharply, Korea’s top three battery manufacturers have been accelerating local investments in response to U.S. tariffs on Chinese products. As a result, opportunities for core partners like Shinsung ST are becoming increasingly visible.
Shinsung ST, which identified this trend early, has already undertaken aggressive facility investments targeting the North American market. With its facility setup nearing completion, the company plans to leverage the new capital injection to finalize the “last puzzle piece” needed for mass-production readiness.
