Sustainable Growth Advisers, LP on Arista Networks
Thesis
SGA initiated Arista as a high-performance networking leader whose EOS software architecture, reliability and product performance have created a strong position with hyperscalers and cloud providers. Although most revenue is hardware, the business has repeatability from data-center expansion, network refresh cycles and the operational switching costs created once Arista is standardized inside a customer's infrastructure. SGA expects the migration from 100G to 400G and 800G networking plus the buildout of AI and cloud workloads to sustain long-term demand. Strong margins and pricing power reinforce the view that Arista can compound through future network expansion cycles.
“We view Arista as a high-quality, long-term compounder”
Key risks
- Competition from Cisco and potential new entrants.
- Customer concentration among large hyperscalers.
