As of Q3'26 (2025-12-31), ARM reported a Revenue Surprise % of -15.50% and a YoY Revenue Growth of 26.35%. This indicates that while revenue grew significantly compared to the previous year, actual results fell short of analyst expectations for the quarter. Over the period from Q2'24 (2023-09-30) to Q3'26 (2025-12-31), ARM's Revenue Surprise % has shown considerable volatility, with notable positive surprises in Q1'25 (16.27%) and Q4'25 (16.62%), but also significant negative surprises in Q3'25 (-19.88%) and Q3'26 (-15.50%). Meanwhile, YoY Revenue Growth has generally remained strong, peaking at 46.60% in Q4'24 and maintaining double-digit growth throughout the observed quarters, despite some fluctuations. This trend suggests robust underlying revenue expansion, though the company has struggled with consistently meeting or exceeding market expectations.
