民生证券-半导体行业点评：商务部发起反倾销调查，模拟IC迎国产替代新机遇-250915

Core Viewpoint - The Chinese Ministry of Commerce announced anti-dumping investigations on U.S. imported analog chips and anti-discrimination investigations related to U.S. measures in the integrated circuit sector, effective from September 13, 2025 [1][2]. Industry Summary - The domestic analog chip market has a low localization rate, with U.S. manufacturers holding significant market shares. In 2024, Texas Instruments (TI) is expected to generate approximately $3.012 billion from Chinese customers, accounting for 19% of its revenue, while Analog Devices, Inc. (ADI) is projected to earn around $2.129 billion, representing about 23% [2]. - The combined revenue from TI and ADI in 2024 from the Chinese market exceeds $5 billion, indicating a substantial presence of U.S. companies in the analog chip market and highlighting the potential for domestic alternatives [2]. Company Summary - The anti-dumping investigation is a response to the significant increase in imports of general interface and gate driver chips from the U.S., which rose by 37% from 2022 to 2024, while import prices dropped by 52%. This has severely impacted the gross margins of domestic companies [2]. - The investigation marks a policy escalation aimed at promoting domestic production of analog chips, reflecting a clear commitment to accelerate the localization of the analog IC industry [2][3]. - Companies likely to benefit from this trend include Sirepu, Naxin Micro, Shengbang Co., Nanchip Technology, Aiwei Electronics, Jiewate, Jingfeng Mingyuan, and Meixin Sheng [3].
