Thesis Summary

Arista entered the second half of 2026 with exceptional operating momentum: Q2 revenue increased 37.7% year over year to $3.036 billion, non-GAAP operating margin reached 49.9%, and management guided Q3 revenue to approximately $3.3 billion. The 1.6 Tbps Etherlink roadmap, relationships with major cloud and AI customers, and expansion into campus, branch, SD-WAN, and security provide multiple growth vectors. However, the August 28 closing price of $195.38 was close to the $214.89 52-week high, embedding demanding execution expectations.

Bear CaseDownside scenario
$185.0023%

AI-network deployment timing slows, supply or tariff pressure reduces profitability, or planned 1.6 Tbps products slip, causing revenue or operating margin to fall below management's Q3 outlook and prompting a material expectations reset.

Base CaseCentral scenario
$241.8258%
Matches the consensus mean

Arista broadly delivers its approximately $3.3 billion Q3 revenue outlook and 48%-49% non-GAAP operating-margin range, while AI networking and enterprise expansion remain healthy but valuation upside is moderated by the high expectations reflected in the August 28 share price.

Bull CaseUpside scenario
$289.0019%

Sustained AI-cluster investment, successful Q4 2026 and Q1 2027 introductions of the 7060XE7 family, and continued adoption across cloud, campus, routing, SD-WAN, and security support growth above current expectations while margins remain near recent levels.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.
