Summary of Key Points from Conference Call Records Industry Overview 1. PCB (Printed Circuit Board) - The PCB sector has shown weak performance since Q4 of last year, primarily due to divergent market views on orthogonal backplane solutions, with some believing they may be replaced by copper cables/CPO or delayed until 2028. However, the orthogonal backplane is currently progressing steadily and is expected to enter mass production in H2 2027. Leading companies are experiencing stock price stagnation due to these divergences, highlighting their cost-effectiveness. Recommended companies include Dongshan Precision, Shenghong Technology, and Huidian Co. [1] - The CoWoP (Chip on Wafer on PCB) solution has stronger certainty, can reduce costs, improve efficiency, and bypass the shortage of substrate capacity. The value per square meter of PCB may increase several times, potentially reaching tenfold, with product launches expected by the end of 2027 and full implementation in 2028. Recommended companies in this direction include Pengding Holdings, Shennan Circuit, and Xinsong Technology. [1] 2. Storage - Contract prices remain in an upward cycle despite fluctuations in spot prices. Module companies are expected to see explosive Q1 performance, with Jiangbolong and Demingli realizing low-priced inventory. Recommended design companies include Zhaoyi Innovation (with a profit expectation of 6 billion) and Puran Co., Beijing Junzheng, and Hengshuo Co. [2] - Demand for memory modules is driven by AI servers and general servers, with recommendations for Lanke Technology (long-term profit of 10 billion) and Jucheng Co. (long-term profit of 1.5 billion). [2] 3. Communication - The recent decline in optical modules is related to the pullback of US tech stocks and speculation around CPO concepts. However, industry sources (such as Coherent and Xuchuang) indicate that CPO's potential to replace optical modules in ScaleOut scenarios is low, suggesting that short-term speculation may be excessive. [2] - North American cloud service providers have exceeded capital expenditure guidance for 2026 (620 billion, up 65% year-on-year), indicating potential accelerated demand for optical modules in 2027. Key upcoming catalysts include Nvidia's quarterly report (February 26), GTC conference (March), and OFC exhibition (NPO product showcase). Recommended companies include Zhongji Xuchuang, Xinyisheng, and Dongshan Precision. [2] - For copper connections as a Plan B alternative to orthogonal backplanes, companies to watch include Luxshare Precision, Wokai Nuclear Materials, and Huiju Technology (with potential for stock doubling). [2] - The price of scattered fiber has surged in the short term (from 25 to 50 yuan), but the low willingness of operators to raise prices raises doubts about long-term sustainability. [2] 4. Computing - Domestic computing resources are in short supply, with the recent downtime of Qianwen highlighting the scarcity of AI foundational resources. The demand for CPUs is expected to rise due to increased usage of agents compared to chatbots. Recommended companies include Haiguang Information (benefiting from both CPU and GPU), Cambrian (leading domestic AI chip manufacturer), and Tianshu Zhixin (expected to accelerate integration with leading players). [2] - Cloud infrastructure resources are expected to benefit from price increases, with recommendations for Kingsoft Cloud, Wangsu Technology, and Fourth Paradigm. [2] - In the AI application sector, the recent drop in overseas software and restructuring of SaaS business models may lead to a narrative reversal with the launch of native agent products in Q3 2026. Companies to watch include Alibaba for 2C entry reconstruction and third-party AI agents like TaxFriend, Zhongkong Technology, and Dingjie Smart. [2] 5. Media - Tencent has faced a decline due to market concerns over potential tax increases on internet platforms, although there is no space for increased game value-added tax. The company remains recommended despite rumors of Q4 earnings downgrades, maintaining a PE ratio of 15 times, which still offers value. [3] - The download situation for the Yuanbao app remains stable, and Tencent's AI capabilities may be closing the gap with larger competitors. [3] - In gaming, companies with upcoming catalysts such as Giant Network and Perfect World are recommended for short-term focus, while Century Huatong and Kaiying Network are suggested for medium to long-term attention due to expected catalysts. [3] - Tencent's establishment of a separate AI comic app is beneficial for the production side, which is entering a period of profitability. Recommendations include Kuaishou, Huanrui, and Rongxin. [3] 6. Pharmaceuticals - Attention is drawn to the update of the essential drug catalog, which may accelerate progress. [4] - The probability of inclusion in the essential drug catalog is high for unique products, with several specific products from companies like Jichuan Pharmaceutical and Panlong Pharmaceutical being highlighted. [4] - Emphasis on the global competitiveness of the innovative drug industry chain, with a focus on new-generation ADCs, IOs, small nucleic acids, and CGT. Recommended companies include Kanghong, Yingen, Yunding, and Chengdu Xian Dao. [4] - The brain-computer interface theme is noted, with a potential showcase of non-invasive products during the Spring Festival and a semi-invasive product approval for Borui Kang in March. [4] - Recommendations include Meihua Medical, Dongwei Semiconductor, and Sanbo Brain Science. [5] - The surgical robot sector is expected to see comprehensive implementation of charging policies before August, with overseas orders doubling and maintaining high growth in 2027. Key types include laparoscopic and orthopedic robots, with strong overseas performance for laparoscopic robots. Recommended companies include MicroPort, Jingfeng Medical, Tianzhihang, and Sanyou Medical. [6]
