GoPro beat Wall Street's forecasts on Thursday as revenue more than doubled from a year earlier, sending shares as much as 14 percent higher in after-hours trading.
However, the stock erased those gains, falling some 15 percent, after it projected unexpectedly weak first-quarter profit and announced the surprise departure of one of its executives.
During its earnings call, the company said it sees first-quarter earnings coming in between 15 and 17 cents per share. Wall Street had expected the camera maker to post earnings 17 cents per share, according to a consensus estimate from Thomson Reuters.
Separately, GoPro Chief Operating Officer Nina Richardson has resigned, the company disclosed in a regulatory filing. Her exit is effective Feb. 27.
