Arista Networks was named a Leader in the 2026 Gartner® Magic Quadrant™ for Enterprise Wired and Wireless LAN – The recognition reflects Arista's continued momentum in the enterprise campus, built on its unified, single-EOS architecture spanning the data center to the campus edge.
Arista introduced the 7060XE7 Series, a next-generation 1.6-terabit portfolio for AI fabrics – The new Etherlink™ platforms deliver up to 100 Tbps of system bandwidth and support Linear Pluggable Optics, cutting interconnect power consumption by approximately 60% compared to traditional pluggable optics.
Arista detailed new innovations for scale-up, scale-out, and scale-across AI fabrics – The company outlined techniques including multi-planar leaf-spine designs, the open Multipath Reliable Connection (MRC) protocol, and segment routing over IPv6 (SRv6), aimed at maximizing AI cluster utilization and resilience.

Financial Outlook

For the third quarter of 2026, we expect:

Revenue of approximately $3.3 billion;
Non-GAAP operating margin of 48 - 49%; and
Non-GAAP diluted net income per share between $1.06 and $1.08.

Guidance for non-GAAP financial measures excludes certain items, including stock-based compensation expense, intangible asset amortization, tax benefits on stock-based awards, the income tax effect on non-GAAP exclusions, and potential non-recurring charges or benefits. A reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available on a forward-looking basis without unreasonable effort because these exclusions can be uncertain or difficult to predict, including stock-based compensation expense and tax benefits on stock-based awards, which is impacted by the timing of employee stock transactions, and the future fair market value of the company’s common stock. The actual amount of these exclusions will have a significant impact on the company's GAAP gross margin, operating margin, and net income per share.

Prepared Materials and Conference Call Information

Arista's executives will discuss the second quarter 2026 financial results on a conference call today at 1:30 PM Pacific Time. To listen to the call via telephone, dial (888) 330-2502 in the United States or +1 (240) 789-2713 from international locations. The Conference ID is 5655862.

Non-GAAP Financial Measures

This press release and accompanying table contain certain non-GAAP financial measures, including non-GAAP gross profit, non-GAAP gross margin, non-GAAP income from operations, non-GAAP operating margin, non-GAAP net income, and non-GAAP diluted net income per share. These non-GAAP financial measures exclude stock-based compensation expense, intangible asset amortization, gains/losses on strategic investments, and the income tax effect of these non-GAAP exclusions, including the recognition of direct excess tax benefits associated with stock-based awards. Effective the fourth quarter of fiscal year 2025, the company updated its methodology for calculating the income tax effect of non-GAAP adjustments. Previously, the company’s calculation excluded all tax benefits associated with stock-based awards, consisting of both direct excess tax benefits and other discrete indirect effects. Under the updated methodology, the company continues to exclude direct excess tax benefits but no longer excludes the discrete indirect effects of such awards. Management believes this change better aligns with industry practice and provides a more meaningful view of the company’s effective tax rate. All prior period non-GAAP results presented in this release have been recast to conform to the current period presentation.

The company uses these non-GAAP financial measures internally in analyzing its financial results and believes that these non-GAAP financial measures are useful to investors as an additional tool to evaluate ongoing operating results and trends. In addition, these measures are the primary indicators management uses as a basis for its planning and forecasting for future periods.

Non-GAAP financial measures are not meant to be considered in isolation or as a substitute for the comparable GAAP financial measures. Non-GAAP financial measures are subject to limitations and should be read only in conjunction with the company's consolidated financial statements prepared in accordance with GAAP. Non-GAAP financial measures do not have any standardized meaning and are, therefore, unlikely to be comparable to similarly titled measures presented by other companies. A description of these non-GAAP financial measures and a reconciliation of the company’s non-GAAP financial measures to their most directly comparable GAAP measures have been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.
