Arista Networks Inc., a networking-software maker, posted better-than-expected results for its fourth quarter on Thursday with sales soaring 41%.
Shares of the company, down 6.5% over the past 12 months, rose 5.76% to $61.50 in after hours trading.
Arista said results were boosted by the ongoing shift to cloud-based networks.
For the current quarter, the company said it expected to post revenue between $232 million and $240 million, in line with estimates of $234 million made by analysts surveyed by Thomson Reuters.
For the period ended Dec. 31, Arista reported a profit of $43.9 million, or 60 cents a share, up from $31 million, or 43 cents a share, a year earlier. Excluding one-time items, adjusted per-share earnings were 80 cents, up from 53 cents a year earlier.
Revenue rose 41% to $245.4 million.
Analysts polled by Thomson Reuters expected per-share profit of 60 cents and revenue of $241.1 million.
Last month, the company leveled antitrust allegations against Cisco Systems Inc., escalating a legal battle that began when Cisco accused Arista of infringing its patents and copyrights.
