British chip designer Arm, owned by SoftBank, reported a conservative outlook for its annual revenue, forecasting between $1bn and $1.1bn for the current quarter, leading to a 9% drop in shares after hours. Despite a 34% year-over-year revenue increase to $1.2bn for the last quarter, uncertainty over US tariff policies and the impact on global supply chains for clients like Nvidia and Apple has left Arm with “lower visibility” into demand, prompting a cautious approach to future guidance. As the company navigates these challenges, it continues to finalize new licensing agreements while its shares have seen a 3% decline since the year’s start.
