Soitec and NSIG to agree extension of licensing framework

Bernin (France), March 13, 2026 – Soitec, a world leader in the design and manufacture of innovative semiconductor materials, and Shanghai-based National Silicon Industry Group Co., Ltd. (NSIG) have agreed to a 10-year extension to their manufacturing and commercial licensing framework, in response to growing Chinese demand for Soitec SOI products and technologies. The agreement remains subject to final approval, including ratification by NSIG’s shareholders expected to be obtained by March 31, 2026.

The agreement with NSIG subsidiaries Simgui and Simwings extends the existing licensing framework underpinning their longstanding partnership, with no new technology transfer and a joint commitment to strengthen Soitec’s SOI intellectual property rights in China. It reinforces Soitec’s position in China’s fast-growing engineered substrates market.

NSIG is a longstanding Soitec shareholder and has been an industrial partner for over a decade, with a ~5.8% stake in the Group as of March 2026.
