China’s antitrust regulator has determined that Nvidia Corporation violated the terms of a 2020 merger deal with Israeli networking firm Mellanox Technologies, escalating regulatory scrutiny on U.S. technology firms and adding new strain to ongoing U.S.-China trade discussions. The State Administration for Market Regulation (SAMR) announced the findings of a preliminary investigation into Nvidia’s $6.9 billion acquisition of Mellanox, stating that the company breached certain conditions imposed when the merger was approved.
The conditions reportedly required Nvidia to maintain supply commitments to Chinese clients, particularly regarding Mellanox’s high-performance networking products such as InfiniBand technology. SAMR initiated the probe in late 2024 following complaints from several domestic firms about restricted access to Mellanox components. While the preliminary decision stops short of imposing penalties, it marks a significant move by Chinese authorities against a major U.S. semiconductor company. The case remains under review pending further regulatory steps.
Nvidia has not publicly responded to the announcement. The company had previously disclosed in regulatory filings that it was subject to Chinese merger control rules and that compliance with foreign laws and regulations could impact its international operations. Mellanox, known for its data center networking technologies, has been a key part of Nvidia’s efforts to expand into high-performance computing and AI infrastructure.
Nvidia stock reacts to Chinese antitrust decision
The regulatory action follows a series of antitrust and compliance reviews in China targeting foreign technology companies. It also comes as U.S. and Chinese officials are meeting in Madrid for trade and economic talks aimed at stabilizing relations between the world’s two largest economies. Representatives from both countries, including U.S. Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng, are attending the bilateral meetings.
Nvidia’s shares declined by more than 2 percent in premarket trading following the SAMR announcement. The stock movement reflected investor concerns about potential financial or operational impacts if China imposes penalties or restrictions. Nvidia derives approximately 13 percent of its annual revenue from China, based on the company’s fiscal year ended January 2025. Under China’s Anti-Monopoly Law, companies found in violation may face fines ranging from 1 percent to 10 percent of their annual revenue in the country.
Chinese compliance reviews increase for US tech firms
However, SAMR has not specified whether fines or remedial actions will be imposed at this stage. Further details are expected after a final ruling is issued. The Mellanox deal, which closed in April 2020, had initially undergone regulatory reviews in multiple jurisdictions, including the United States, European Union, and China. China granted approval with behavioral conditions designed to ensure continued product availability and fair market access.
Nvidia’s integration of Mellanox has since become central to its strategy in cloud computing and artificial intelligence sectors, where high-speed interconnects are critical to system performance. This development highlights the growing complexity multinational firms face in managing regulatory compliance across different legal regimes. It also underscores the increasing importance of antitrust enforcement in China’s approach to overseeing foreign mergers involving key technologies. As of now, Chinese regulators have not indicated when a final decision will be made or what additional measures may follow. – By Content Syndication Services.
