Persistent growth
For the second quarter, Arista generated record revenue of $3.3 billion, up 40% year over year and 12% sequentially. This resulted in non-GAAP earnings per share (EPS) of $1.02, also up 40%.
For context, analysts' consensus estimates called for revenue of $2.83 billion and adjusted EPS of $0.89, so the company soared past expectations.
"As we deliver our first $3 billion quarter in Q2 2026, it is clear that our Arista 2.0 platform strategy is compelling," stated Jayshree Ullal, Chairperson and CEO of Arista Networks. "Customers see networking as the central nervous system for infrastructure from the client to campus to data and AI centers."
The company has positioned itself to succeed in the age of artificial intelligence (AI), developing the next generation of data center networking components that are fast becoming the industry standard.
Helping to propel the stock higher was management's robust outlook for the upcoming third quarter. Arista is forecasting revenue of $3.3 billion and non-GAAP EPS of $1.07, both at the midpoint of its guidance. This was well ahead of Wall Street's consensus estimates for revenue of $2.95 billion and EPS of $0.92.
It's important to note that Arista's robust performance doesn't come cheap. The stock is currently selling for 43 times next year's expected earnings. That said, the company has positioned itself to ride the twin secular tailwinds of cloud computing and AI adoption. Arista's successful track record shows it deserves a premium.
