SANTA CLARA, Calif.- May 5, 2026 -- 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 first quarter ended March 31, 2026.

First Quarter Financial Highlights

"Arista is off to a strong start in Q1 2026, with both our results and our industry-leading net promoter score," said Jayshree Ullal, Chairperson and CEO of Arista Networks. “We are uniquely positioned to deliver the mission-critical confluence of secure client-to-campus-to-cloud and AI networking.”

•Revenue of $2.709 billion, an increase of 8.9% compared to the fourth quarter of 2025, and an increase of 35.1% from the first quarter of 2025.

•GAAP and non-GAAP operating margin of 42.7% and 47.8%, respectively, compared to GAAP and non-GAAP operating margin of 42.8% and 47.8% in the first quarter of 2025.

•GAAP and non-GAAP diluted earnings per share of $0.80 and $0.87, respectively, compared to GAAP and non-GAAP diluted earnings per share of $0.64 and $0.661 in the first quarter of 2025.

A reconciliation of the company’s non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included in this press release.

Commenting on the company's financial results, Chantelle Breithaupt, Arista’s CFO, said, ”We are proud of our strong start to Fiscal 2026. While the macro and supply chain environments remain dynamic, our results are a testament to our team's disciplined execution. Delivering 35% revenue growth alongside $0.87 non-GAAP EPS demonstrates our ability to drive high-quality growth while maintaining a rigorous focus on the bottom line."

Company Highlights

•Arista announced XPO high-density liquid-cooled pluggable optics – Designed for next-generation AI data centers, XPO reduces networking racks by up to 75% and saves up to 44% of floor space compared to traditional pluggable optics, enabling shorter cable runs and lower-power AI scale-up interconnect technologies such as copper and RF.

•Arista received a 2026 NPS Score of 89 – The updated net promoter score indicates that 94% of customers are strongly positive about the company. These industry-leading metrics are a testament to the company’s focus on driving customer success and satisfaction.

•Powering AI Centers with AI Spines – Arista introduced the universal AI spine powered by the 7800 to deliver massive scale, predictable performance, and high‑speed interface support. Powerful features such as Virtual Output Queuing (VOQ) eliminate head‑of‑line blocking and large buffers absorb AI microbursts and prevent PFC storms.

Financial Outlook

For the second quarter of 2026, we expect:

•Revenue of approximately $2.8 billion;

•Non-GAAP operating margin of 46 - 47%; and

•Non-GAAP diluted net income per share of approximately $0.88.

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.
