Ambarella investors shouldn't underestimate Qualcomm's ability to win over GoPro. GoPro's current CFO, incoming CFO, and VP of Corporate Development and Investor Relations all previously worked at Qualcomm. During last quarter's conference call ( as transcribed by Thomson Reuters ), GoPro CEO Nick Woodman declared that the Hero 5 would be the company's "most connected and convenient GoPro" to date -- strongly indicating that it might use a 4G-connected SoC like Qualcomm's. Ambarella could be in deep trouble if that happens.
