Zhongji Innolight's 10.47% stake and liquid-cooling/CPO demand drive Jones Tech

Zhongji Innolight buys 10.47% stake for 1.747 billion yuan Optical module giant Zhongji Innolight agreed to buy 10.47% of Jones Tech from its controlling shareholders at 55.70 yuan per share, a 1.747 billion yuan deal. The strategic investor brings confidence and potential heat-dissipation synergies as high-end optical modules ramp up. Control stays unchanged.
This is the single biggest new force behind the stock, bringing a deep-pocketed strategic partner and validating Jones Tech's thermal materials business.
China's first data center liquid cooling national standard released China approved its first national standard for cold-plate liquid cooling in data centers, effective February 2027. Tightening energy rules and AI server power density are forcing liquid cooling adoption. Jones Tech, which makes thermal materials, jumped 20% on the news as a direct beneficiary.
A new regulation creates a durable, policy-backed demand wave for Jones Tech's core thermal products.
Nvidia CPO switches enter mass production, lifting optical supply chain Nvidia said its Spectrum-X silicon photonics switches are in full mass production, cutting power use and laser counts. Jones Tech hit a second straight 20% limit as a CPO concept stock. Faster CPO adoption means more optical modules and more heat to manage, supporting demand for its materials.
It ties Jones Tech to a fast-growing technology cycle that expands the market for its thermal and shielding products.
Stake transfer registration completed, making Zhongji Innolight a major shareholder The 1.747 billion yuan transfer was registered on September 29, so Zhongji Innolight now officially holds over 5% of Jones Tech. The deal is done, not just planned. Jones Tech's first-half 2026 revenue rose 10.66% and profit rose 13.59%, and the stock is up over 122% this year.
Completion removes deal uncertainty and confirms the strategic partnership is real, a fresh milestone beyond the August announcement.

Ronbay Swings to Profit, Expands Sodium-Ion Capacity

First-half profit turnaround Ronbay returned to profit with 109 million yuan net income, versus a loss last year, as revenue rose 39.57% on higher shipments and better overseas plant use. This shows the core business is recovering, which supports the stock price.
This is the key financial result that directly improves investor confidence and valuation.
Sodium-ion cathode expansion Ronbay plans to invest 4.723 billion yuan in a 300,000-tonne sodium-ion cathode plant, with first phase starting August 2026. Sodium-ion products are already shipping at scale, positioning the company for future growth beyond lithium.
This major investment signals a new growth engine and long-term capacity leadership.
Lithium manganese iron phosphate full production The company's LMFP business is running at full capacity with all output sold, and sales rose about 50% year-on-year. This high-demand product line boosts revenue and shows strong market acceptance.
It highlights a key product driving current sales and profitability.
Industry-wide capacity expansion risk Rising material prices have triggered about 30 billion yuan of new projects across the battery supply chain, including Ronbay's. While this meets current demand, it could lead to oversupply and margin pressure later, a risk to watch.
It provides a balanced view of the competitive and pricing risks from collective expansion.
