Background & analysis
On November 4, 2026, Arista Networks released its third-quarter financial results. Revenue for the quarter rose 58.5% year over year to $3.66 billion, while adjusted EPS came in at $1.20. Both figures beat Wall Street's expectations, with revenue roughly 10% above the $3.33 billion analysts had projected, and adjusted EPS above the anticipated $1.08 and up 60% from the prior-year period. According to the report, the 58.5% revenue growth rate is the fastest annual growth Arista has recorded since its 2014 IPO, marking an acceleration in demand for networking infrastructure from AI. For the fourth quarter, Arista guided revenue to $3.9-$4.0 billion, with a midpoint of about $3.95 billion, well above the $3.6 billion the market had estimated, and guided adjusted EPS to a range of $1.26-$1.30. Following the announcement, Arista's shares climbed around 10% in after-hours trading. CEO Jayshree Ullal stated that the third-quarter performance even exceeded her own elevated expectations, and that the strong momentum across customer segments demonstrates Arista's growing strategic value in the era of generative AI and agentic AI. The report attributes the quarter's growth to a surge in demand for AI data center infrastructure. As of now, the latest available update on the company remains this earnings release.
