On the evening of September 24, a number of companies listed in Shanghai and Shenzhen disclosed major filings tied to artificial intelligence, computing power infrastructure and semiconductors. From additional investment in AI data centers, to expanded optical fiber and CPO capacity, to the launch of AI and semiconductor investment funds, players up and down the supply chain are moving faster.

Sinnet Adds Investment in AI Data Center

Sinnet (300383) said it plans to invest up to an additional 1.265 billion yuan in its Horinger AI data center project. That brings total project investment to roughly 2.5 billion yuan.

IT load capacity will rise from the originally planned 60 to 100 megawatts to 90 to 120 megawatts, while the cabinet count moves from 3,200 to between 7,000 and 10,000.

The company said the expansion will further raise the AI data center's computing power capacity, better serving growing demand for AI training and inference workloads.

Hengtong Optic-Electric Plans 6.636 Billion Yuan Private Placement

Hengtong Optic-Electric (600487) plans to issue shares to specific investors, raising no more than 6.636 billion yuan in total.

According to the filing, proceeds will fund next-generation optical fiber R&D and production, high-end optical materials in Inner Mongolia, CPO advanced packaging, data intelligence communications and advanced AI optical interconnect, alongside marine energy interconnection and smart maintenance, a deep-sea cable-laying vessel, a smart manufacturing base, and working capital.

The CPO advanced packaging and advanced AI optical interconnect projects speak directly to rising high-speed interconnect demand inside AI data centers. As computing power clusters grow larger, optical fiber, optical modules and advanced packaging are becoming core pieces of AI infrastructure.

E-Government Plans 576 Million Yuan Server Purchase

E-Government (300075) said Zhengtong Zhisuan (Jinan) Technology Co., Ltd., a wholly owned second-tier subsidiary, signed a server procurement contract with a company identified only as Company A. Cumulative purchases are expected to total 576 million yuan, with the tax-inclusive amount equal to 15.06% of the company's most recent audited total assets.

The company said the purchase will provide key infrastructure for its computing power service projects. Once the contract is fulfilled and the equipment deployed, it expects to strengthen its computing power supply and service capability and round out its computing power business.

The size of the server order reflects growing demand for computing power resources from government digitalization, urban administration and industry AI applications.

China Life to Commit 4.5 Billion Yuan to AI and Semiconductors

China Life (601628) said it and other investors plan to jointly establish an equity investment partnership with total committed capital of no more than 6 billion yuan.

China Life's own commitment would be capped at 4.5 billion yuan. The partnership will focus on high-quality unlisted equity in artificial intelligence and semiconductors.

The plan shows long-term capital moving into the AI and semiconductor industries through equity investment, giving companies in the sector medium- to long-term financial backing.

Kinwong Moves Into RISC-V High-Performance AI CPUs

Kinwong (301041) said its wholly owned subsidiary Shenzhen Kinwong Technology Co., Ltd. will commit 10 million yuan of its own funds as a limited partner in Gongqingcheng Yaocan Venture Capital Partnership.

Gongqingcheng Yaocan plans to raise 65 million yuan in total, earmarked for a company developing a full-stack, in-house high-performance RISC-V AI CPU.

RISC-V is open and extensible, and has drawn attention in recent years in servers, edge computing and AI chips. The investment marks Kinwong's first step toward building exposure to a self-controlled AI processor ecosystem through an industry fund.

Ronbay-listed Lopal to Build AI Innovation Center

Lopal Tech (603906) said it plans to invest up to 500 million yuan in a global headquarters and an AI-driven innovation center for new energy and new materials.

The project will center on the global headquarters, the new energy and new materials business, and AI applications, and is expected to bring more intelligent tools into R&D, production, supply chain management and business decision-making.

In a separate filing, the company said controlled subsidiary Changzhou Liyuan will inject 310 million yuan into its wholly owned subsidiary Jiangsu Liyuan, which will remain wholly owned by Changzhou Liyuan after the capital increase.

The AI Supply Chain Enters a Phase of Coordinated Expansion

Taken together, the filings show listed companies shifting from single-project AI bets to coordinated pushes across AI data centers, servers, optical fiber, CPO, chips, industry funds and smart manufacturing centers.

On one side, growing demand for AI model training and inference keeps driving AI data center buildouts and server purchases. On the other, larger computing power clusters are accelerating work on high-speed optical interconnect, advanced packaging and homegrown AI chips.

At the same time, insurance capital, corporate industrial capital and local investment platforms are taking bigger roles in AI and semiconductor equity deals. As funding, equipment, chips and use cases line up more closely, the AI supply chain looks set to move from isolated projects toward systematic development.
