The Transaction was considered as part of Ushio’s ongoing efforts to improve capital efficiency and optimize its business portfolio, in line with its new growth strategy, "Revive Vision 2030," formulated in 2024.

With over 40 years of expertise in optical technology, Ushio operates a business producing high-power, highly reliable semiconductor laser devices across a broad wavelength range, from blue-violet to infrared. It offers competitive products and technologies, particularly in the area of red lasers using GaAs (gallium arsenide) substrates. Meanwhile, Kyocera is engaged in the development of RGB laser diodes for road projection* in automotive applications and AR glasses in the metaverse sector. By combining the technologies and expertise of both companies, the Transaction should enhance the value we deliver to our customers.

Through the "Revive Vision 2030" initiatives, Ushio will work to maximize its corporate value by revamping its business portfolio and improving capital efficiency. It remains committed to contributing to the realization of a sustainable society as the Light Innovation company.
