SK Innovation plans to merge with SK IE Technology (SKIET) to reduce costs and financial risks in its separator business, focusing on growth in the energy storage system (ESS) market amid stagnation in electric vehicle demand. The merger aims to optimise costs, capitalise on ESS opportunities, and improve profitability within three years.

This Wire brief sits within Fusion42's coverage of Clean Energy.

◆ The Wire takeaway

SK Innovation’s merger with SKIET shifts cost burdens within its battery material supply chain and opens new growth routes in energy storage systems. You should rethink your supplier and partner strategies in EV and ESS markets in South Korea to capitalise on this structural change.
