China says Nvidia broke competition rules, extends probe; stock off lows

China's market regulator has extended an antitrust probe into Nvidia concerning its 2020 Mellanox acquisition, citing preliminary evidence of competition law breaches, which initially caused Nvidia shares to dip before largely recovering. This action comes amidst ongoing U.S.-China trade negotiations and follows Nvidia's recent instruction to suppliers to halt production of its H20 chips for the Chinese market due to security concerns. While potentially impacting Nvidia's China sales, some analysts interpret the probe as political posturing by Beijing to gain leverage in broader trade discussions, maintaining a bullish long-term outlook on the stock.

Analysis

China's market regulator has extended its antitrust probe into Nvidia (NVDA) concerning the 2020 acquisition of Mellanox, citing preliminary findings of competition law violations. This regulatory action, which initially sent the stock down over 2% in premarket trading before a significant recovery, coincides with high-level U.S.-China trade negotiations in Madrid. The probe adds another layer of complexity to an already tense relationship, marked by ongoing tariffs and Nvidia's recent directive for suppliers like Amkor Technology and Samsung to halt production of H20 chips designed for the Chinese market. An analyst from Mizuho characterized the probe as "noise and pure posturing" by Beijing to gain leverage in trade talks, rather than a fundamental threat. This viewpoint is supported by a bullish long-term outlook on the stock, with the analyst highlighting a compelling risk/reward based on a projected mid-20s P/E ratio for FY27 against potential 50% EPS growth.

Key Decisions for Investors

• Investors should closely monitor the U.S.-China trade negotiations and the progression of the antitrust probe, as these represent the primary short-term risk factors for Nvidia's China-related revenue.
• For long-term investors, the analyst's valuation thesis of a compelling risk/reward below $180 per share suggests the current geopolitical noise could present a buying opportunity, assuming the fundamental growth story remains intact.
• The halt in H20 chip production highlights tangible supply chain disruptions; it would be prudent to review exposure to other semiconductor firms heavily reliant on either Chinese market sales or manufacturing, such as Amkor Technology.
