Chinese Chipmaker InnoLight Buys $245 Million Stake in Tech Firm
Chinese optical module manufacturer Zhongji Innolight (stock code 300308.SZ) announced on September 30 that it has completed the transfer of a 10.47% stake in Shenzhen-listed Zhongshi Technology, according to a company filing. The deal, valued at 1.747 billion yuan (about 245 million US dollars), was finalized on September 29, 2026, after the shares were formally registered under Innolight’s name.
The shares were acquired from Zhongshi Technology’s controlling shareholders — Wu Xiaoning, Ye Lu, and an entity named HANWU — who together sold 31.3725 million shares. Following the transaction, Zhongji Innolight directly holds the same 10.47% stake in Zhongshi Technology, making it one of the company’s significant shareholders. The purchase was made through a negotiated agreement rather than open-market trading.
Zhongji Innolight is a major player in the global optical module market, supplying high-speed transceivers used in data centers and telecommunications networks. Its products are essential for cloud computing, artificial intelligence infrastructure, and 5G networks. The company is headquartered in Suzhou, Jiangsu province, and is listed on the Shenzhen Stock Exchange’s ChiNext board, which hosts many of China’s fast-growing technology firms.
Zhongshi Technology, also listed in Shenzhen, specializes in thermal management materials and electromagnetic shielding components. Its products are used in consumer electronics, communications equipment, and new energy vehicles. The company’s technologies help manage heat and reduce electromagnetic interference in electronic devices — both critical for high-performance computing and electric vehicles.
The acquisition appears to be a strategic move by Zhongji Innolight to deepen its ties with a key supplier or partner in the electronics supply chain. By taking a significant minority stake, Innolight can potentially secure better access to thermal management solutions, which are increasingly important as optical modules and data center equipment become more powerful and generate more heat.
The transaction is also notable for its size relative to recent merger and acquisition activity in China’s technology sector. While not a full takeover, the 1.747 billion yuan deal represents a substantial investment and signals continued consolidation and vertical integration within the country’s electronics manufacturing ecosystem.
For global investors, the deal highlights the ongoing maturity of China’s tech supply chain, where companies are using capital markets to strengthen relationships and secure critical components. It also reflects the broader trend of Chinese firms investing in upstream and downstream partners to improve efficiency and competitiveness.
Both companies are expected to continue their normal operations. The share transfer does not involve any change in Zhongshi Technology’s management or business strategy, according to the filing. The transaction was conducted as a negotiated agreement, a common method for large block trades in China’s A-share market.
As the global demand for data center infrastructure and electric vehicles continues to grow, partnerships like this one between Zhongji Innolight and Zhongshi Technology may become more common. The deal underscores the importance of thermal management and advanced materials in the next generation of electronics, and it positions Zhongji Innolight to benefit from these trends through its new equity stake.
