Sustainable Growth Advisers, LP on Arista Networks, Inc.
Thesis
SGA initiated Arista Networks for its high-performance, software-driven networking platform used by hyperscalers and cloud customers. Its EOS operating system and focused architecture support scalability, automation and reliability, while gross margins around 60-65% and operating margins above 40% demonstrate pricing power. Once deployed, Arista becomes deeply embedded in customer operations, creating switching costs and recurring participation in data-center expansion and network-upgrade cycles. Structural demand for 400G and 800G networking, cloud infrastructure and AI workloads provides a long runway. SGA views Arista as a high-quality long-term compounder despite supply and competitive risks.
“We view Arista as a high-quality, long-term compounder well-positioned to benefit from the structural buildout of data center networking”
Key risks
- Competition from Cisco and new entrants
