A 62-year-old wealthy woman has transferred all her core assets to her son, with the combined wealth of the mother and son reaching 40 billion yuan.

On the evening of December 29, HEC (600673) disclosed that due to Guo Meilan's advanced age, she signed an "Equity Transfer Agreement" with her son Zhang Yushuai, transferring all of her 71.75% equity stake in Ruyuan Yao Autonomous County Yuneng Electronic Industrial Co., Ltd. (hereinafter referred to as "Ruyuan Yuneng Electronic") and her 74.63% equity stake in Ruyuan Yao Autonomous County Xinjing Technology Development Co., Ltd. (hereinafter referred to as "Ruyuan Xinjing Technology") to Zhang Yushuai.

Following the equity ratio adjustment, Guo Meilan no longer holds any equity in Ruyuan Yuneng Electronic and Ruyuan Xinjing Technology and no longer indirectly holds shares in HEC; Zhang Yushuai will indirectly hold 100% equity of Shenzhen HEC Industrial Development Co., Ltd. (hereinafter referred to as "HEC Group") through Ruyuan Yuneng Electronic and Ruyuan Xinjing Technology, thereby indirectly holding 1.165 billion shares of HEC, accounting for 38.70% of the listed company's total share capital. The actual controller of the listed company will change from Zhang Yushuai and Guo Meilan to Zhang Yushuai alone.

Guo Meilan was born in 1963, and Zhang Yushuai was born in 1987; both mother and son are from Dongyang, Zhejiang Province. On the 2025 Hurun Rich List, Guo Meilan and Zhang Yushuai ranked 146th with a fortune of 40 billion yuan.

(with shareholding ratios of 58% and 42%, respectively).

HEC Group is the controlling shareholder of HEC, directly holding 620 million shares of the listed company and indirectly holding 545 million shares of the listed company through its controlled subsidiary, Yichang HEC. As of the market close on the 29th, the market value of HEC shares directly and indirectly held by HEC Group was approximately 26 billion yuan.

Additionally, Guo Meilan also indirectly controlled 50.9787% of the equity in Hong Kong-listed company SUNSHINE PHARMA (06887.HK) through entities including Ruyuan Yuneng Electronic and Ruyuan Xinjing Technology. Currently, the total market capitalization of SUNSHINE PHARMA is approximately HKD 24.831 billion.

According to public information, in 2011, the then 24-year-old Zhang Yushuai joined HEC Group, serving successively as Director of the Biology Institute of Dongguan HEC Pharmaceutical Research Institute, and Director of the Generic Drugs Institute and Vice President.

In November 2020, HEC announced that one of the company's actual controllers, Mr. Zhang Zhongneng, had passed away due to illness, and his controlled interests in the listed company were inherited by his son, Zhang Yushuai.

Under Zhang Yushuai's leadership, HEC Group has achieved high-quality development across three major industries: electronic new materials, biomedicine, and health wellness. In 2023, the Group's total output value exceeded 51 billion yuan, reaching a record high. According to its official website, the Group's total assets have surpassed 80 billion yuan, with cumulative tax payments exceeding 20 billion yuan, and it has entered the list of China's Top 500 Private Enterprises.

Currently, the business expansion and capital operations of HEC Group are continuing.

On August 7 this year, HEC Group facilitated the overall listing of SUNSHINE PHARMA on the Hong Kong Stock Exchange, completing its long-standing plan to achieve an overall listing for its pharmaceutical industry.

In mid-September, HEC announced its intention to acquire a 100% stake in the leading service provider in the computing power sector, Chindata Group China, for 28 billion yuan, aiming to achieve a business closed-loop from "hardware technology to computing power operations."

In early December, while participating in a related event, Zhang Yushuai clearly stated that HEC will partner with Chindata Group in the future to actively build a vertically integrated industrial ecosystem from core materials to end applications, deeply integrate into the AI wave, focus on constructing computing power guarantee bases, and enhance the synergy among data, computing, electricity, and network resources.
