Nvidia shares tumbled over 18 percent in premarket trading Friday after missing on revenue and guidance in its third quarter 2019 earnings report.

The company missed analyst expectations of $3.24 billion per Refinitiv, with the company recording $3.18 billion for the quarter. Guidance for the fourth quarter was $2.70 billion, plus or minus 2 percent, excluding certain items. That compares to the Refinitv consensus estimate of $3.40 billion.
