Summary of Conference Call Notes Company and Industry Involved - The focus is on the PCB (Printed Circuit Board) industry, specifically companies such as 生益科技 (Shengyi Technology), 沪电股份 (Unimicron Technology), and 胜宏科技 (Shenghong Technology) [1][2]. Core Points and Arguments 1. Market Concerns Addressed: - The cancellation of orthogonal backplane is deemed false; a new round of samples has been ongoing since February, with expectations for NVIDIA to showcase related content at the GTC conference [2]. - There is no clear information on material downgrades; clients are advancing multiple parallel solutions, with the industry trends for M8 and M9 continuing to strengthen [2]. - PCB's strong asset nature leads to a step-up trend in capacity; the second half of 2025 to the first half of 2026 will see a vacuum period for new capacity release among leading PCB companies, resulting in a temporary decline in performance growth rates [2]. - AI products can quickly pass on cost increases, making the impact on leading companies manageable [2]. 2. Key Recommendations: - Reaffirmed recommendations for 生益科技, 沪电股份, and 胜宏科技 as key stocks to watch [1]. 3. Upcoming Events and Innovations: - The NVIDIA GTC conference is anticipated to showcase innovations such as orthogonal backplanes and CPO, which could act as significant catalysts for the computing and PCB sectors [3]. - Incremental applications are expected to solidify by year-end, supporting visibility for industry growth in the coming years [3]. 4. LPU Chips: - LPU chips are expected to become a significant addition to NVIDIA's inference landscape, benefiting PCB upgrades and increasing the proportion of PCB in AIBoM from 3%-5% to 5%-10% [3]. 5. Price Increase Logic: - High copper prices and rising electronic fabric costs, along with shortages in high-end T-glass fabric, are expected to support accelerated price increases for copper-clad laminates, BT substrates, and ABF substrates [3]. - Since Q4 2025, price increases of approximately 15%-20% for copper-clad laminates (FR4), BT/ABF substrates have been realized, with further increases of 10%-20% anticipated in the first half of 2026, potentially leading to significant profit elasticity for related companies [3]. Other Important but Possibly Overlooked Content - The ongoing developments in the PCB industry, particularly regarding new technologies and materials, are crucial for investors to monitor as they may influence future performance and market dynamics [2][3].
