Chip designer Arm Holdings reported a surge in quarterly revenue, exceeding analyst estimates, and forecast fiscal second-quarter sales in line with analyst estimates. Arm's chief financial officer said they see more investment in artificial intelligence than even 90 days ago. Arm generates revenue from licensing fees for its semiconductor designs and royalties on every chip sold using its technology. Arm's designs power nearly all smartphones, and the company is trying to expand into data centers and other markets. Arm's shares fell despite the strong revenue results.
