Arista Networks Q2 2026 Results and Outlook

Arista Networks, Inc. (NYSE: ANET) reported second‑quarter 2026 results that substantially exceeded analyst expectations, prompting a roughly 13% rise in its share price during pre‑market trading on Wednesday.

The company posted adjusted earnings per share of $1.02, beating the consensus estimate of $0.88 by $0.14. Revenue reached $3.04 billion, surpassing the consensus forecast of $2.83 billion and representing a 37.7% year‑over‑year increase from $2.20 billion in Q2 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 period a year earlier. Deferred revenue growth, however, decelerated to roughly 70% of the prior quarter, down from the 90‑100% range observed in earlier quarters.

Purchase commitments for the quarter jumped to $9.7 billion, a sharp rise from the $3‑$3.6 billion range recorded a year ago, suggesting that demand across AI, campus, and core data‑center switching remains robust.

Looking ahead, Arista issued third‑quarter 2026 guidance that significantly outpaced consensus. The company forecast revenue of approximately $3.3 billion, well above the consensus estimate of $2.95 billion. Adjusted EPS guidance was set between $1.06 and $1.08, with the midpoint of $1.07 representing a 16% premium to the consensus of $0.92.

CEO 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.” CFO Chantelle Breithaupt highlighted that second‑quarter revenue grew 37.7% while adjusted EPS increased 39.7% versus the prior‑year period.

Bank of America analysts noted that despite the slowdown in deferred revenue growth, the company continues to “fire on all cylinders” with accelerated demand across AI, campus, and core data‑center switching, and they view the surge in purchase commitments as evidence of a strong demand environment.
