[M&A Focus] Semiconductor Industry Chain Vertical Integration: Kaide Quartz Control Rights Change

On February 5, 2026, the actual controllers of Beijing Kaide Quartz Co., Ltd., Zhang Zhongshu and Wang Yumin, along with their concerted parties, transferred the company's control rights to Ningbo Jiangfeng Electronics. Jiangfeng Electronics convened an extraordinary shareholders' meeting on February 27, 2026, where the proposal to acquire Kaide Quartz's control rights was reviewed and approved. Currently, the transaction still requires compliance confirmation from the Beijing Stock Exchange and the completion of the final transfer registration procedures. This event represents a change in control rights in the upstream segment (quartz materials) of the semiconductor industry chain, constituting a vertical integration within the hardware sector that may impact the landscape of the related material supply chain.
