Enterprise Leads Blockbuster 4Q for Arista – but Wall Street's Not Impressed

Arista reported a blockbuster fourth quarter, with revenues up 42.7% year-over-year to $467.9 million, and full-year revenue of $1.6 billion, up 45.8% compared with fiscal 2016.But Wall Street was unhappy, with stock trading down 14% after hours on Thursday on soft projections for this year. (See Arista 4Q Revenue Up 42.7% YoY to $467.9M.)Arista topped 4,900 customers, with Microsoft accounting for 16% of revenue for the year. The fourth quarter saw an "unusual bump," making enterprise the top vertical market, with the sector Arista calls "cloud titans" the second-largest.Cloud titan share fell due to delays getting products certified to meet the requirements of US government import decisions related to intellectual property litigation brought by arch-rival Cisco, Arista CEO Jayshree Ullal said on a call with financial analysts Thursday afternoon.For the full year, cloud titans were the top market sector, followed in by a tie between service providers, cloud specialty providers and enterprise for second place and financials trailing behind. Arista expects that trend to continue this year.Figure 1:Arista CEO Jayshree Ullal.

Sign up for the weekly Enterprise Cloud News newsletter."For the first time in nearly two decades of stagnant IT, Arista is offering a compelling alternative," Ullal said. "Legacy vendors are on the wrong side of this trend." Arista is converging LAN, WAN, Layer 2 and Layer 3 integration to make its products more useful to network operators.Last year was an "inflection year" for routing and 100Gbit/s Ethernet products, and Arista leads market share in that category, Ullal said. The company will enter the 400Gbit/s Ethernet market next year. On the software side, Arista delivered containerized data analytics and hybrid cloud in conjunction with Amazon, Microsoft, Google and Equinix.Arista sees artificial intelligence as a "huge long-term driver" for networking growth, and is working with storage providers and Nvidia. "The network is clearly going to require more and more bandwidth for 100Gbit/s Ethernet workloads, and in the future 400 [Gbit/s] will become an important requirement for the vast amount of data crunching and analytics required on AI workloads," Ullal said.Arista is continuing to be successful in its intellectual property lawsuits and counter-suits with Cisco, though products are taking longer to clear for import than anticipated.

Executive Editor, Light Reading

San Diego-based Mitch Wagner is many things. As well as being "our guy" on the West Coast (of the US, not Scotland, or anywhere else with indifferent meteorological conditions), he's a husband (to his wife), dissatisfied Democrat, American (so he could be President some day), nonobservant Jew, and science fiction fan. Not necessarily in that order.

He's also one half of a special duo, along with Minnie, who is the co-habitor of the West Coast Bureau and Light Reading's primary chewer of sticks, though she is not the only one on the team who regularly munches on bark.

Wagner, whose previous positions include Editor-in-Chief at Internet Evolution and Executive Editor at InformationWeek, will be responsible for tracking and reporting on developments in Silicon Valley and other US West Coast hotspots of communications technology innovation.
