Ambarella reported a robust top-line acceleration in Q4 FY2025, delivering revenue of $84.0 million, up 62.8% year over year and flat-to-moderately up quarter over quarter. Gross profit reached $51.14 million with a gross margin of approximately 60.9%, underscoring a healthy product cost structure despite ongoing investments in R&D. However, the company remains unprofitable on an after-tax basis, posting an operating loss of $25.35 million and a net loss of $20.23 million for the quarter. The negative earnings are driven by sustained high research and development spend relative to revenue, though operating cash flow was positive at $25.43 million and free cash flow was $21.25 million, aided by favorable working capital movements. Ambarella ended the period with a strong balance sheet: cash and cash equivalents of about $144.6 million and total liquidity (cash plus short-term investments) near $250.3 million, yielding a net cash position of roughly $139 million. The result positions Ambarella well to pursue AI-enabled edge semiconductor opportunities in automotive, security, and robotics, but execution is essential to translate revenue growth into sustained profitability.
