The Company has developed the magnetic-induction wireless charging technology for mobile devices, and it is producing various 5W-15W
wireless charging TX products for diverse devices. In 2019, it took over the wireless business department of Samsung and
established Wits Co., Ltd. to expand the business to produce and supply wireless charging RX products as well.

Instead of settling for the magnetic-induction wireless charging technology, the Company is conducting R&D for magnetic-resonant-coupling
wireless charging technology, through which it has plans to enhance the utility of wireless charging to expand and lead the market.
