ISU PETASYS rose more than 2% intraday on the 27th on expectations that it will benefit from Google's artificial intelligence (AI) semiconductor, the tensor processing unit (TPU).
As of 9:51 a.m., ISU PETASYS was trading at 144,500 won on the Korea Exchange, up 2,900 won (2.05%) from the previous session. It rose for a third straight session and hit an intraday 1-year high of 149,300 won.
Analysts said expectations for Google's AI model "Gemini 3" are lifting ISU PETASYS' share price. As expanding data center TPU servers is essential for AI model training, ISU PETASYS is seen as a key TPU supplier. ISU PETASYS is said to hold about a 40% share of Google's TPUs.
Park Sang-hyun, an analyst at Korea Investment & Securities, said, "TPU volumes are set to increase steadily, and shipments of high-bandwidth switches such as 800G will also expand in earnest," and added, "Demand is solid while supply growth is limited, so the average selling price (ASP) will trend higher throughout the year."
