Analysis
Arista reported revenue of $3,035.7 million in the second quarter of 2026, its first $3+ billion revenue quarter. Revenue increased 37.7% from the second quarter of 2025 and 12.1% compared with the first quarter of 2026. Product revenue was $2,605.2 million and service revenue was $430.5 million. Management characterized the performance as strong, broad-based growth and linked its platform strategy to client, campus, data center, and AI infrastructure.
Profitability expanded at the operating level. GAAP income from operations was $1,378.0 million, with a 45.4% operating margin compared with 44.7% in the prior-year quarter. Non-GAAP income from operations was $1,513.7 million and non-GAAP operating margin was 49.9%, compared with 48.8%. GAAP net income was $1,212.9 million and GAAP diluted net income per share was $0.95. Non-GAAP net income was $1,301.7 million and non-GAAP diluted net income per share was $1.02, compared with $0.73 in the second quarter of 2025.
Gross-margin performance deserves attention because it moved lower year-over-year despite the stronger revenue and operating-margin results. GAAP gross margin was 62.9%, compared with 65.2%, while non-GAAP gross margin was 63.4%, compared with 65.6%. Total operating expenses were $532.3 million, including $348.2 million of research and development expense, $150.3 million of sales and marketing expense, and $33.8 million of general and administrative expense.
Cash generation was substantial over the first six months. Net cash provided by operating activities was $2,776.5 million, compared with $1,841.8 million in the prior-year six-month period. At June 30, 2026, cash and cash equivalents were $2,290.2 million and marketable securities were $11,053.1 million. The filing reported no repurchases of common stock for the six months ended June 30, 2026, while purchases of property and equipment were $84.2 million.
For the third quarter of 2026, Arista expects 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. The outlook calls for revenue above the reported second-quarter level while indicating a non-GAAP operating-margin range below the second-quarter 49.9% result. The company also highlighted 1.6 Tbps AI fabric platforms, liquid-cooled options, and the 7060XE7 Series as product developments supporting AI fabric deployments.

AlphAI analysis generated from the company’s SEC earnings filing (Form 8-K Item 2.02, or Form 6-K for a foreign private issuer). Every figure was cross-checked against the filing text; consensus estimates, price targets and share-price reactions are not shown because they are not in the filing. AI-generated research, not investment advice.
Background
This is an SEC Form 8-K (Item 2.02) attaching Arista’s Q2 2026 results and Q3 2026 outlook, including product and AI fabric platform updates.
Ticker impact
Arista reported Q2 2026 revenue of $3.036B and guided Q3 2026 revenue to about $3.3B with non-GAAP EPS $1.06 to $1.08.
Bias toward upside follow-through if the market focuses on the $3.3B revenue guide and margin outlook.
The filing is a primary earnings release with quantified results and forward guidance (revenue, non-GAAP operating margin, and non-GAAP diluted EPS range), which typically moves expectations and estimates quickly.
Market effects
Reinforces demand signals for AI fabric and high-speed Ethernet switching, supporting the broader data-center networking capex narrative.
Primarily US-listed large-cap tech sentiment, with potential spillover to other networking and semiconductor names exposed to AI infrastructure spending.
AI networking demand and guidance can influence global supply-chain expectations for optical/interconnect and data-center equipment.
Counterpoint
Non-GAAP metrics exclude items like stock-based compensation and amortization, so the market may discount the headline EPS/margins versus GAAP profitability.
