Arista Networks stock approaches its November 3 report after a record quarter and a higher full-year revenue outlook. AI demand remains central.

Growth Meets A Higher Earnings Bar

Arista raised its fiscal 2026 revenue outlook to USD 12.6 billion after its first quarterly revenue above USD 3 billion.
Management expects third-quarter revenue of about USD 3.3 billion and adjusted earnings per share of USD 1.06 to USD 1.08.
The November 3 report will test AI-networking demand, margins and the premium attached to the stock.

Arista Networks is heading into its third-quarter report with stronger sales expectations but a demanding valuation test. The company is scheduled to release results after the U.S. market close on Tuesday, November 3, for the quarter ended September 30.

Arista Networks stock traded at EUR 153.63 on Lang & Schwarz at 16:15 CEST on Friday, October 30. The real-time quote of Arista Networks stock is available here.

Raised Outlook Raises The Stakes

In its second quarter, Arista reported revenue of USD 3.04 billion, up 37.7 percent from a year earlier, according to 24/7 Wall St. Non-GAAP earnings per share reached USD 1.02 against a USD 0.89 consensus estimate, while the company lifted its fiscal 2026 revenue outlook to USD 12.6 billion, equivalent to 40 percent growth.

Management guided for third-quarter revenue of about USD 3.3 billion and adjusted earnings per share of USD 1.06 to USD 1.08. Investors will therefore focus on whether demand is translating into higher sales without eroding profitability.

AI Demand And Margins In Focus

AI networking remains the central growth driver. Arista counts more than 100 cumulative Etherlink customers and targets at least USD 3.5 billion in AI fabrics revenue this year, while new 1.6-terabit switches are expected to move from trials toward production in 2027.

Margin performance is another key issue. The source said gross margin fell to 63.4 percent in the second quarter from 65.6 percent a year earlier, reflecting customer mix and rising memory and silicon costs. Management expects pricing actions to provide more support toward the end of 2026 or in 2027.
