Advantest Shares Hit Record High as Strong Earnings and AI Boom Drive Growth

Advantest Corp. (TYO:6857) saw its shares soar to a record high on Wednesday, climbing as much as 16% to 21,220 yen after the semiconductor testing equipment maker reported robust fiscal second-quarter results and raised its annual guidance. The surge helped lift Japan’s Nikkei 225 index by 1.3%, which also reached a new peak.

The company’s operating profit jumped nearly 71% year-over-year to 108.4 billion yen ($710 million) for the July–September quarter, fueled by a 38% rise in revenue to 262.9 billion yen. Advantest’s impressive earnings were driven by growing demand from artificial intelligence (AI) and semiconductor sectors, particularly as a key supplier to NVIDIA Corporation (NASDAQ:NVDA). The ongoing global AI boom continues to push spending on advanced chips and testing equipment, boosting Advantest’s performance.

Building on its strong quarterly performance, Advantest raised its full-year operating profit forecast by 25% to 374 billion yen. The company also lifted its fiscal 2026 sales projection to 950 billion yen, up from the previous estimate of 835 billion yen, while net income is expected to reach 275 billion yen, compared to prior guidance of 221.5 billion yen.

With demand for AI infrastructure and semiconductor innovation showing no signs of slowing, Advantest’s growth trajectory mirrors NVIDIA’s rise over the past two years. Investors have rewarded this momentum, pushing Advantest’s stock up approximately 124% so far in 2025. The company’s strategic positioning in the AI-driven semiconductor supply chain continues to make it one of Japan’s most valuable technology stocks, reflecting both strong fundamentals and long-term market confidence.
