About this update from Arista Networks, Inc.

SANTA CLARA, Calif., February 12, 2026 --( BUSINESS WIRE )--Arista Networks, Inc. (NYSE: ANET), an industry leader in data-driven, client-to-cloud networking for large AI, data center, campus, and routing environments, today announced financial results for its fourth quarter and the full year ended December 31, 2025. "2025 was the year of validation of our Arista 2.0 momentum, as we hit the milestone of shipping a cumulative of 150 million ports," stated Jayshree Ullal, Chairperson and CEO of Arista Networks. "We exceeded both our AI networking and campus expansion goals, delivering profitable growth and revenue of $9 billion." Fourth Quarter Financial Highlights Full Year Financial Highlights "Our Q4 results underscore the strong operating leverage inherent in our model, providing a powerful exit rate as we head into 2026," said Chantelle Breithaupt, Arista’s CFO. "By pairing 29% revenue growth with a disciplined 47.5% operating margin, Arista achieved a historic milestone: surpassing $1 billion in quarterly net income. Congratulations to the team." Fourth Quarter Company Highlights Full Year Company Highlights Financial Outlook For the first quarter of 2026, we expect: Guidance for non-GAAP financial measures excludes certain items, including stock-based compensation expense, intangible asset amortization, 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 which is impacted by the timing of employee stock transactions, the company’s future hiring and retention needs 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 and GAAP operating margin.

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, as well as non-recurring adjustments to our tax provision resulting from the enactment of the One Big Beautiful Bill Act ("OBBB Act"). Effective the fourth quarter and 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.
