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.

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.
