SAS succession complete as founder Mingguang Lu exits board amid diversified growth

Lu Mingguang’s board exit at SAS marks more than succession—it signals accelerated governance localization under U.S.-China tech decoupling pressure. Technically, SAS is pivoting from bulk silicon wafers toward an integrated compound semiconductor and advanced packaging stack, forcing equipment and EDA vendors to dual-certify for Taiwan, China and mainland production lines. Compliance costs are rising sharply: expanded BIS controls on epitaxial tools compel SAS to build redundant supply chains by 2025, lifting operational expenses by 12–15%. Japanese and Korean rivals like Shin-Etsu and SK Siltron may seize share in mature nodes but can’t replicate SAS’s SiC substrate IP moat. Over the next 18 months, SAS will shift from capex-led expansion to IP licensing and JVs, with Southeast Asia emerging as a strategic hedge against geopolitical tariffs.
