Rohm (6963) re-evaluated on Nvidia partnership, AI power semiconductors
Rohm Co., Ltd. shares advanced significantly as investors re-evaluated the Japanese chipmaker's strategic partnership with Nvidia and its prospects in energy-saving power semiconductors for AI servers. The stock, trading under symbol 6963, rose 9.7% to ¥4,386 on May 14, 2026, up from its ¥4,000 previous close.
The surge reflects renewed interest in Rohm's role as a silicon provider for Nvidia's 800V HVDC data centre power infrastructure, a collaboration initially announced in May 2025. This "Nvidia-related" and "physical AI-related" theme, alongside the company's AI server semiconductor offerings, has previously driven sharp gains, with PayPay Securities noting a 13% jump on similar news.
This latest upward movement follows the company's fiscal year ending March 2026 earnings announcement on May 12, 2026, which reported a net loss due to substantial impairment charges and a ¥50 dividend. Despite the reported loss, expectations for growth in automotive and data centre segments, coupled with ongoing structural reforms, appear to be attracting short-term capital into AI power-related themes. Shares had also risen 6.9% on May 11, 2026, following reports of a tailwind for Rohm's automotive and industrial semiconductors from increasing AI demand.
Why Rohm's AI Server Chip Ambitions Are Driving Its Stock
Rohm Co., Ltd. is a Japanese electronics firm specialising in semiconductors, particularly power semiconductors and large-scale integrated circuits (LSIs). These components are fundamental to modern technology, efficiently controlling electricity and processing information in everything from electric vehicles and smartphones to industrial machinery and data centres. Rohm generates revenue by supplying these high-performance, energy-saving solutions to a broad customer base.
Today's share price surge primarily stems from renewed investor confidence in Rohm's power semiconductors for AI servers, specifically through its collaboration with NVIDIA. The market is re-evaluating Rohm's role as a silicon provider in NVIDIA's 800V HVDC data centre power infrastructure concept, first outlined in May 2025, alongside its own recent announcements of semiconductors tailored for AI server applications. This forward-looking growth potential is overshadowing a recent large impairment charge that resulted in a deficit, with investors viewing the "bad news" as largely accounted for.
Consequently, Rohm's stock has risen by exactly 9.7% today, trading at ¥4,386, up from yesterday's close of ¥4,000. This reflects the market's strong recognition of AI-related growth expectations materialising through concrete partnerships and products.
Imagine a cutting-edge software company that recently posted a quarterly loss due to a one-off restructuring cost. However, simultaneously, it was revealed they had secured an exclusive deal to develop the core AI engine for a major new gaming console from a leading manufacturer. The temporary financial dip becomes less significant than the promise of future, high-impact revenue from a pivotal role in a booming industry.
