Arista Networks is a premier hyper-growth compounder in data center networking, benefiting significantly from cloud computing expansion and AI infrastructure tailwinds. Its software-driven EOS model drives industry-leading margins and robust revenue growth. Anchored heavily on forward earnings (60% weight) to capture near-term momentum, our composite fair value lands tightly at $184.49, implying substantial 30% upside. Elite ROIC and robust structural demand perfectly justify the aggressive valuation architecture. Fair value range: low $104, high $276, with mid-point at $184.

§2 Cas baissier

A severe margin compression scenario combined with delayed 800G Ethernet upgrade cycles would critically challenge the 30x terminal multipleTerminal multipleThe exit P/E or EV/EBITDA we apply to the final year of an explicit forecast. Anchored to the business's long-run quality and the prevailing risk-free rate.. If AI networking adoption drastically lags and InfiniBand decisively wins the backend interconnect war, Arista's hyper-growth trajectory violently decelerates.
