These numerous A-share companies addressed various market hotspots in their announcements, including artificial intelligence, robotics, tungsten hexafluoride, and photoresists for liquid crystal panels. They urged investors to view these popular themes objectively and rationally and to be mindful of investment risks.
Two Companies Address AI Supply Chain
Crystal Optech Co., Ltd. (Shui Jing Guang Dian) stated in its announcement that while market attention on its AI optics business is high, this segment primarily involves optical storage and optical connection businesses.
The company's optical storage business is currently in the pre-mass-production verification phase and has not generated sales revenue since 2025. Due to the lengthy product process verification cycle, it will take time for this business to achieve significant scale.
Its optical connection business focuses on five categories: "filters, prisms, silicon lenses" and "glass substrates, waveguides," forming a "3+2" product matrix. Among these, filter and silicon lens products are currently in the customer sampling stage, while advanced products like glass substrates and waveguides are in early-stage technical discussions, with none contributing to performance yet.
The announcement clarified that over the past two years, the core driver of the company's earnings growth has been its consumer electronics business with a major North American client. AI optics, as a key innovative business under strategic development, has a long project implementation and earnings realization cycle, offering limited contribution to overall performance in the short term.
As of the close on July 2nd, shares of Crystal Optech were at 39.02 yuan, down 0.03%, with a total market capitalization of 54.26 billion yuan.
Li Hu Gu Fen announced that market interest in its projects, such as AI liquid cooling, is notable, but these projects are still in the preliminary preparation stage and have not yet generated sales revenue.
As of the close on July 2nd, shares of Li Hu Gu Fen rose 9.84% to 11.83 yuan, with a total market capitalization of 2.568 billion yuan.
Four Companies Comment on Robotics Sector
Xiang Yuan New Material Co., Ltd. (Xiang Yuan Xin Cai) announced that the piezoresistive foam material (PU) and piezoelectric foam material (IXPP) it produces for robot pressure sensors and piezoelectric sensors are still in the sampling and verification stage. These have not yet resulted in substantive sales, and there is significant uncertainty regarding future revenue generation.
As of the close on July 2nd, shares of Xiang Yuan New Material rose 6.89% to 33.50 yuan, with a total market capitalization of 4.625 billion yuan.
Aishida Co., Ltd. (Ai Shi Da) stated that its current main businesses are cookware, home goods, small appliances, and industrial robots. In 2025, the revenue from its industrial robot segment was 309 million yuan, accounting for a small proportion of total revenue, and the segment remains loss-making.
As of the close on July 2nd, shares of Aishida rose 4.18% to 10.22 yuan, with a total market capitalization of 3.481 billion yuan.
Fulai New Material Co., Ltd. (Fu Lai Xin Cai) announced that while market attention on the humanoid robot concept is high, the current revenue from its flexible sensor project is 1.82 million yuan (unaudited), representing an extremely low proportion of overall revenue and having no significant impact on its core operations.
As of the close on July 2nd, shares of Fulai New Material rose 10% to 34.32 yuan, with a total market capitalization of 10.36 billion yuan.
Mould-Tech Co., Ltd. (Mo Su Ke Ji) stated that its primary business remains plastic automotive exterior trim components, with no major changes. It has only secured a small-batch procurement order for robot exterior coverings, with the order value accounting for less than 0.1% of operating revenue, having a minimal impact on operating performance.
As of the close on July 2nd, shares of Mould-Tech rose 9.97% to 16.87 yuan, with a total market capitalization of 15.49 billion yuan.
Two Firms Clarify Positions on Tungsten Hexafluoride and Photoresist
Heyuan Gas Co., Ltd. (He Yuan Qi Ti) addressed what it called false rumors circulating on some investor platforms, which claimed that "customs data shows Hubei exported 20 tons of tungsten hexafluoride in May this year, which was exported by the company."
The company clarified in its 2025 annual report that the series of electronic specialty gas products planned at its Yichang and Qianjiang electronic specialty gas industrial parks are currently in the trial production stage. Among these, only electronic-grade carbon monoxide, high-purity ammonia, carbonyl sulfide, and silane have achieved sales, but their sales proportion is less than 5%.
The announcement stated that planned products like electronic-grade tungsten hexafluoride are still in trial production. The process from stable production to mass production and capacity ramp-up takes considerable time, with capacity release potentially falling short of expectations. The product certification cycle is long, and the company has not yet obtained formal certification from leading downstream domestic and international semiconductor companies. It has not exported any tungsten hexafluoride products, signed any orders, or generated any performance from this, and it is not expected to have a significant impact on operating performance for the next two to three years.
As of the close on July 2nd, shares of Heyuan Gas rose 10% to 75.02 yuan, with a total market capitalization of 15.8 billion yuan.
Baihehua Co., Ltd. (Bai He Hua) announced that upon verification, the related high-performance pigment products it produces are used in the field of photoresists for liquid crystal panels. However, in 2025, the sales revenue from photoresist pigments accounted for only 0.084% of its operating revenue.
As of the close on July 2nd, shares of Baihehua rose 7.82% to 61.22 yuan, with a total market capitalization of 25.49 billion yuan.
