First Quarter Financial Highlights

“As we enter 2025, AI, cloud, and enterprise customers continue to drive network transformation. We surpassed $2B in revenue for the first time in Q1 2025 despite the unknowns around tariffs," stated Jayshree Ullal, Chairperson and CEO of Arista Networks. "Arista's trifecta of innovation, growth, and profitability is reflected in our results."

• Revenue of $2.005 billion, an increase of 3.9% compared to the fourth quarter of 2024 and an increase of 27.6% from the first quarter of 2024.
• GAAP gross margin of 63.7%, compared to GAAP gross margin of 63.8% in the fourth quarter of 2024 and 63.7% in the first quarter of 2024.
• Non-GAAP gross margin of 64.1%, compared to non-GAAP gross margin of 64.2% in the fourth quarter of 2024 and 64.2% in the first quarter of 2024.
• GAAP net income of $813.8 million, or $0.64 per diluted share, compared to GAAP net income of $637.7 million, or $0.50 per diluted share in the first quarter of 2024.
• Non-GAAP net income of $826.2 million, or $0.65 per diluted share, compared to non-GAAP net income of $637.7 million, or $0.50 per diluted share in the first quarter of 2024.

Commenting on the company's financial results, Chantelle Breithaupt, Arista’s CFO, said, "With a continued focus on execution, Arista maintained its financial performance of delivering both strong growth and profitability. In Q1 2025, we also completed the highest level of stock repurchases in Arista's history, quarterly or annually, at $787M, reflecting our strong conviction in the long-term value of the business."

Stock Repurchase Program

In May 2025, Arista’s Board of Directors authorized an additional program to repurchase up to $1.5 billion. The actual timing and amount of repurchases will be dependent on market and business conditions, capital requirements, stock price, acquisition opportunities and other factors.

Company Highlights

Cluster Load Balancing (CLB) in Arista EOS ® maximizes AI workload performance with consistent, low-latency network flows, while Arista CloudVision® Universal Network Observability™ (CV UNO™) now offers AI job-centric observability for enhanced troubleshooting and rapid issue inference, ensuring job completion reliability at scale.
• Arista Networks Recognized in the Leaders Quadrant of the 2025 Gartner® Magic Quadrant™ for Data Center Switching, published on March 31, 2025 - Gartner positioned Arista Networks as the vendor with the highest ability to execute in the report.

Financial Outlook

For the second quarter of 2025, we expect:

• Revenue of approximately $2.1 billion
• Non-GAAP gross margin of approximately 63%; and
• Non-GAAP operating margin of approximately 46%.

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. In addition, non-GAAP financial measures exclude net tax benefits associated with stock-based awards, which include excess tax benefits and other discrete indirect effects of such awards. 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.
