The stock is down by more than 20% before the opening bell after crashing by as much as 27% in after-hours trading on Thursday.
It fell by more than $50 to as low as $184.25 a share, a level last reached around last August.
The company reported non-GAAP earnings per share of 57 cents, in line with expectations. And revenues rose 35% to beat forecasts, at $638 million.
But its Q2 guidance fell short: The company expects EPS of $0.28 on revenues of between $670 million and $675 million. On average, analysts had expected revenue of $717.5 million and EPS of $0.74.
The company's $1.5 billion acquisition of Lynda.com in April will generate up to $25 million in full-year revenue, it said.
