Shares rallied 21% in the premarket following the results. AMBA YTD mountain Ambarella year to date “Ambarella posted a strong quarter with an exceptionally bullish outlook,” wrote Moore. “The inventory correction is now mostly behind them, and 2H revenues will reflect actual end market demand.” “While the current economic environment will be a headwind – global auto production will be down this year and enterprise/consumer markets are mixed – the strength of Ambarella’s technology and rising demand for their new inference chips should more than offset those,” he added. This share price pop will be a welcomed one for Ambarella investors. Year to date, the stock is down more than 13%. — Fred Imbert
