Yuanjie Technology Highlights Risks in Optoelectronic Chip Project
Yuanjie Technology has seen its stock price surge by 74.16% from May 18 to June 22, significantly outperforming relevant indices such as the STAR Market Composite Index and the STAR 50 Index.
The company issued an announcement stating that its Phase II project for the R&D and production base of optoelectronic communication semiconductor chips and devices faces risks of progress and implementation falling short of expectations. The project could also lead to increased financial pressure and a higher asset-liability ratio.
Furthermore, future factors such as an inability to continuously optimize product structure, intensified market competition, high customer concentration, or high R&D costs, weak reliability, and failure to achieve mass production of new products could adversely affect the company's operating performance.
Yuanjie Technology focuses on the optical chip industry, with its main business involving the R&D, design, production, and sales of optical chips, primarily used in telecommunications, data centers, and automotive LiDAR markets.
As of the close on June 22, Yuanjie Technology shares rose 11.96% to 1,873.50 yuan per share, with a total market capitalization of 233.3 billion yuan.
Maijie Technology Provides Update on Collaboration with Nvidia
Maijie Technology announced that regarding its collaboration with Nvidia, only a few inductor product models are currently in the R&D and import phase. The overall business is in a small-batch trial production stage and has not yet formed stable, large-scale supply.
The announcement indicated that due to factors such as high product development difficulty, stringent yield requirements, long international customer qualification cycles, and the international trade environment, the subsequent order fulfillment, production ramp-up, and benefit realization of the collaboration with Nvidia remain uncertain. This business is unlikely to significantly boost the company's overall performance in the short term.
Additionally, in response to recent market rumors of rapid price increases for inductor products, Maijie Technology stated that since the fourth quarter of 2025, prices of upstream raw materials like copper, tin, and silver have risen sharply, making it difficult for downstream companies to bear the costs. Some component prices have increased due to cost pressure being passed on.
The announcement clarified that this round of moderate price adjustments only provides limited repair to product unit gross margins and will not enhance the profitability of the company's component products. Pricing for Maijie Technology's various inductor products follows market conditions, and there is no situation of actively implementing significant price hikes.
The company warned that if precious metal prices continue to climb, it will face ongoing pressure from rising raw material costs. There is a risk that these costs cannot be fully passed downstream, which could directly lead to sustained pressure on the gross margins of core products like inductors, potentially causing the company's annual operating performance to fall short of market expectations.
As of the close on June 22, Maijie Technology shares rose 13.94% to 31.63 yuan per share, with a total market capitalization of 28.07 billion yuan.
Two A-Share Companies Address AI Industry Chain Hotspots
Recent market rumors have involved topics such as "AIDC intelligent computing centers and advanced packaging driving a surge in silicon carbide demand," "silicon carbide entering the 12-inch era," and "companies deeply benefiting from the uptrend in AI computing power and the advanced packaging industry chain."
Jingsheng Co., Ltd. announced that in emerging application scenarios like AIDC and advanced packaging, silicon carbide is currently in a small-batch testing phase. There is significant uncertainty regarding downstream customer qualification and the progress of bulk purchase orders. Large-scale adoption is not expected until the technology achieves scaled implementation in these new downstream application areas.
As of the close on June 22, Jingsheng Co., Ltd. shares rose 15.22% to 92.68 yuan per share, with a total market capitalization of 12.82 billion yuan.
Yutai Micro announced that while there has been market discussion about the company's progress in high-speed DSP electrical chip business, its main business remains the R&D, design, and sales of high-speed wired communication chip products, which has not undergone significant changes. The company does not have DSP electrical chip products for data centers.
Recently, Yutai Micro released a plan for a private placement of A-shares in 2026, intending to use the raised funds for an R&D project focused on a new generation of high-speed interconnection network communication solutions for data center scenarios.
The company stated that the specific R&D outcomes and product forms of the proposed fundraising project remain uncertain, and there is still a significant distance from productization. The project is not expected to have a major impact on the existing core business.
As of the close on June 22, Yutai Micro shares rose 13.74% to 271.60 yuan per share, with a total market capitalization of 21.73 billion yuan.
Zhongchuan Teqi Halts Trading for Verification
Zhongchuan Teqi announced that from May 11 to June 22, its stock price repeatedly hit abnormal volatility thresholds, even reaching severe abnormal volatility, with a cumulative increase of 388.77%. The company plans to suspend trading starting from the market open on June 23 and will resume after disclosing a verification announcement.
As of June 18, Zhongchuan Teqi's rolling price-to-earnings ratio was 535.1 times, and its static P/E ratio was 557.73 times, significantly higher than industry peers, indicating high valuation risks.
Recently, tungsten hexafluoride products have garnered high attention, with market rumors mentioning Zhongchuan Teqi's production capacity, product prices, specifications, and orders for tungsten hexafluoride.
Zhongchuan Teqi clarified that its current annual production capacity for tungsten hexafluoride is 2,000 tons, with product specifications all at 6N grade. The company has never publicly disclosed information regarding the price of its tungsten hexafluoride products.
Regarding product orders, the announcement stated that if relevant contracts reach the disclosure standards stipulated by the Shanghai Stock Exchange's STAR Market Listing Rules, the company will strictly fulfill its information disclosure obligations in a timely manner.
Previously, the company stated via an interactive platform that online rumors about signing a three-year long-term supply agreement with a related enterprise, including product prices and supply share, were verified to be untrue. Currently, discussions with the relevant customer regarding the subsequent supply plan are still ongoing.
Zhongchuan Teqi is primarily engaged in the R&D, production, and sales of electronic specialty gases and trifluoromethanesulfonic acid series products. As of the close on June 22, its shares rose 7.14% to 389.99 yuan per share, with a total market capitalization of 206.5 billion yuan.
