The weekend can't come soon enough for Arista Networks after its stock dropped on the heels of a weak second-quarter forecast.

The cloud-based software provider's stock dropped more than 15% in after-hours trading Thursday night after announcing it had lowered its second-quarter revenue guidance to between $600 million and $610 million, which was below analyst forecasts of $639 million.

Arista's stock, which has seen its value increase 47% this year, opened at $261.90 this morning before increasing to $266.31 by noon.

Arista said it was expecting lower sales in the second quarter due to slow growth by a hyperscale cloud provider. While the firm didn't say which cloud provider was expecting slower growth in the second quarter, analysts pointed to Microsoft, according to a story by MarketWatch.
