Ambarella: It Will Need To Do A Lot To Get Back Investor Confidence

Ambarella, Inc. reported Q4 revenue of $101M (+20% y/y), with IoT segment up 50%, but shares fell 19% post-earnings. I maintain a Hold rating on AMBA, citing stretched valuation (forward PE ~72x) and investor concerns over margin deterioration despite strong IoT growth. Profitability remains the key focus; margin recovery hinges on successful execution of advanced 5nm/4nm chip transition and AI-driven products.
