Kioxia Stocks Fall 16% to Half Peak After Patent Ruling

Kioxia's stock price fell 16.10% to 52,110 yen during afternoon trading on July 17, marking a drop to roughly half its record high set one month earlier. The semiconductor company reached an all-time peak of 112,700 yen on June 22 before declining sharply. The selloff followed overnight weakness in US semiconductor stocks and intensified as South Korea's market remained closed, concentrating selling pressure on Japanese chip equities. A Texas federal district court ruling on the morning of July 17 ordering Kioxia to pay $229 million for patent infringement against US communications firm ViaSat further pressured the stock. The decline reflects broader volatility in global semiconductor equities amid shifting market sentiment.

The court determined that Kioxia infringed on ViaSat's patents related to computer memory technology. According to Nihon Keizai Shimbun, this ruling contributed to downward pressure on Kioxia's share price during the trading session.

Japanese Semiconductor Stocks Decline Amid Market Closure in South Korea

Kioxia's sharp decline affected the broader Japanese equity market on July 17. Advantest fell more than 11% and Tokyo Electron dropped over 9% during the session. Banking stocks including Mitsubishi UFJ Financial Group also declined significantly. Tomoichiro Kubota, chief market analyst at Matsui Securities, stated that some investors appeared to be selling bank stocks to cover losses from Kioxia's plunge. The closure of South Korea's market on this date concentrated semiconductor sector weakness in Japanese equities following overnight selling pressure in US chip stocks.
