Arista Networks Q2 2026 Results and Outlook
Arista Networks, Inc. (NYSE: ANET) posted second‑quarter 2026 results that comfortably exceeded analyst expectations, prompting the stock to climb more than 11% after the market opened on Wednesday. The company reported adjusted earnings per share of $1.02, beating the consensus estimate of $0.88 by $0.14, while revenue reached $3.04 billion, surpassing the $2.83 billion forecast and representing a 37.7% year‑over‑year increase from $2.20 billion in the second quarter of 2025. This quarter marked Arista’s first instance of revenue exceeding $3 billion.
Adjusted operating margin expanded to 49.9%, up from 48.8% in the comparable prior‑year period. Although deferred revenue growth decelerated to roughly 70% in the quarter, down from the 90‑100% range observed in earlier quarters, purchase commitments surged to $9.7 billion, a substantial rise from the $3‑$3.6 billion range a year earlier, suggesting that demand remains robust.
Looking ahead, Arista issued third‑quarter 2026 guidance that significantly outpaced consensus. Revenue is projected at approximately $3.3 billion, well above the $2.95 billion analyst estimate, and adjusted EPS is expected between $1.06 and $1.08, topping the consensus of $0.92; the midpoint of $1.07 reflects a 16% premium to expectations.
Chief Executive Officer Jayshree Ullal commented, “As we deliver our first $3 billion quarter in Q2 2026, it is clear that our Arista 2.0 platform strategy is compelling. Customers see networking as the central nervous system for infrastructure from the client to campus to data and AI centers.” Chief Financial Officer Chantelle Breithaupt highlighted that second‑quarter revenue grew 37.7% and adjusted EPS increased 39.7% versus the prior‑year period.
Bank of America analysts noted that the company continues to “fire on all cylinders with accelerated demand across AI, Campus, and core data center switching,” while also acknowledging that a flattening deferred‑revenue trend could signal a longer‑term risk of slowing order growth.
