While many were hoping that GoPro’s efforts to turn the company around would continue with its Q3 earnings release today, Wall Street did not like what they saw sending GoPro’s stock diving 11 percent after-hours.

GoPro beat expectations handily on both revenue and earnings per share, but it was the company’s poor forward looking guidance that led investors to dump the stock in the aftermath of the release. GoPro announced revenue of $330M on a non-GAAP EPS of $0.15.
