Advantest Corp. has raised its full-year operating profit forecast by 37%, attributing the increase to robust demand for its chip testing tools used in artificial intelligence applications. The company now expects its operating profit to be 2.7 times higher than the previous year, surpassing market expectations. This upward revision comes amidst concerns about the potential impact of Chinese startup DeepSeek on AI-related expenditures, yet the strong demand for chip testers suggests continued investment in AI technologies.
