On the evening of June 26, GigaDevice Semiconductor, a prominent player in China's memory chip industry, made an announcement. It revealed that its controlling shareholder and chairman, Zhu Yiming, had significantly reduced his stake in the company. Specifically, between May 11 and May 25, 2026, Zhu Yiming sold a total of 6.3299 million shares through centralized bidding and block trades, accounting for 0.90% of the company's total share capital.

Following this equity transaction, the combined shareholding ratio of Zhu Yiming and his concerted party, Hong Kong Yingfude Co., Ltd., dropped from 7.90% to 7.00%, crossing the 1% variation threshold. It's worth noting that this share reduction is part of a previously disclosed plan and is yet to be fully implemented.

GigaDevice Semiconductor has witnessed remarkable growth in recent times. Over the past year, its stock price has surged by 358%, propelling its market capitalization to a staggering 368.9 billion yuan. Based on the average stock price of 406.38 yuan during the May 11 - May 25 period, it's estimated that Zhu Yiming may have realized proceeds of approximately 2.572 billion yuan within just 11 trading days.

Interestingly, both GigaDevice Semiconductor and Changxin Technology are under the leadership of Zhu Yiming. From 2023 to 2025, the scale of related-party transactions between these two companies expanded from 764 million yuan to 1.182 billion yuan. And this figure is projected to soar to 5.7 billion yuan in 2026, representing a nearly 6.5-fold increase over a span of four years.

Zhu Yiming, born in 1972 in Yancheng, Jiangsu Province, boasts an impressive academic background. He holds a Master's degree in Electronic Engineering from both Tsinghua University and Stony Brook University, which is part of the State University of New York. Prior to his current role, he spent many years working in memory design in the United States, gaining invaluable experience in the field.
