Zhongji InnoLight invested 1.747 billion in Sinopec Technology, and the optical module leading card position is used for heat dissipation

As optical modules iterate to higher speeds, power consumption and heat dissipation are becoming increasingly critical variables in the development of the optical communications industry.

On the evening of August 13, Zhongji InnoLight issued an announcement announcing that it would acquire a total of 31.3725 million unrestricted shares of Beijing Zhongshi Weiye Technology Co., Ltd. in cash, accounting for 10.47% of the total share capital of Zhongji Technology. The total transaction price was approximately 1.747 billion yuan.

After the transaction is completed, Zhongji InnoLight will become an important shareholder holding more than 5% of the shares of Sinopec Technology, but it will not seek control. The controlling shareholder and actual controller status of Sinopec Technology will remain unchanged.

Sinopec Technology has been deeply involved in the fields of thermal management and electromagnetic compatibility for more than 20 years. Its main business covers the research and development, design, production and sales of high-performance thermal conductive materials, electromagnetic interference shielding materials and power filters.

Its product system has gradually expanded from early high thermal conductivity graphite and thermal interface materials to more complex heat dissipation solutions such as heat pipes, vapor chambers, and thermal modules, forming a complete layout from basic materials to system-level components.

Sinopec’s products are widely used in many high-growth fields such as consumer electronics, 5G communications, data centers, computing power centers, intelligent transportation and clean energy.

Especially in the field of optical communication heat dissipation, the VC module heat dissipation solution launched by Sinopec Technology for high-speed optical modules has passed the certification of domestic and foreign leading customers and has been supplied in batches. The heat dissipation performance and product value have been simultaneously improved.

Buying heat dissipation and PCB, Zhongji InnoLight has densely knitted its high-end computing power supply chain

From an industrial logic point of view, Zhongji InnoLight's strategic investment in Sinopec Technology is a forward-looking position for the leading optical module company in key upstream material links.

Zhongji Xuchuang is a leading enterprise in the field of domestic optical communication modules. It has products covering a full range of optical modules from low speed to 800G and even 1.6T, and deeply serves the construction needs of global data centers, cloud computing and artificial intelligence computing power networks.

As the speed of optical modules evolves from 800G to 1.6T or even higher speeds, the power consumption density of a single module continues to rise, and Zhongji InnoLight is also facing the problem of heat dissipation of optical modules. The optical chips and electrical chips inside the optical module generate a large amount of heat when running at high speed. If the heat dissipation solution is not in place, it will directly affect the signal transmission quality and equipment life.

Sinopec Technology’s technological accumulation in thermal conductive materials and thermal management solutions can form upstream and downstream synergies with InnoLight’s high-end optical module products. Zhongji InnoLight is expected to obtain deeper cooperation in the supply of heat dissipation materials, joint technology development, and collaborative certification with major customers.

In addition to investing in Sinopec Technology, PCB leader Pengding Holdings is also an important part of Zhongji InnoLight's supply chain layout. Recently, the 2026 semi-annual report of PCB leader Pengding Holdings showed that InnoLight Investment, a wholly-owned subsidiary of Zhongji InnoLight, holds 24 million shares of Pengding Holdings. The shares have a market value of approximately 2.32 billion yuan, accounting for 1.04% of the company's total share capital, making it the fourth largest shareholder of Pengding Holdings.

For Zhongji InnoLight, by continuously investing in Sinopec Technology and Pengding Holdings, the company has incorporated the two key links of cooling and PCB into its own industrial ecology, which will help smooth the risk of upstream material price fluctuations, accelerate the introduction of customized cooling solutions and high-end PCBs, and provide more complete system-level solutions when facing overseas core customers such as Nvidia, thus building higher technical barriers in the competition of 1.6T and next-generation products.

For Sinopec and Pengding Holdings, the introduction of optical module leaders as important shareholders will not only bring stable order expectations, but also help to use InnoLight's customer resources to further penetrate into overseas high-end computing power supply chains and enhance brand awareness and market share in the field of optical communications.
