GoPro performed better than expected in the second quarter. Its revenues jumped by 34 percent to $297 million as compared to the corresponding period of 2016, thanks to strong demand for its Heros Black5 camera. Total camera shipments were more than 18 percent higher than in the previous three months of this year. The gross margin of 36.2 percent was 3.9 percentage points higher than in the year-ago period, allowing the company to post positive Ebitda of $5.21 million against a loss of $76.8 million. The net loss fell to $30.5 million from $91.8 million. New product releases later this year should help the company to book even better results.
