Why it matters

  1. What Arista Networks does

    Arista Networks builds high-performance networking gear and software for cloud data centers. Hyperscale cloud providers pay them to move massive data volumes with low latency. Arista is scaling into AI networking to capture surging data center traffic from automated agents.

  2. What it does best

    Arista delivers elite operating margins of 43.1%, beating peers like Cisco at 25.4%. This efficiency stems from a single software image architecture across all switches, making customer expansion frictionless and hard for rivals to copy.

  3. The main risk

    Arista relies heavily on a handful of mega-scale cloud customers for a huge slice of its revenue. If even one hyperscaler slows down data center builds, volume growth takes an immediate hit.

Quality, check by check

Scored against its own industry, from company filings.

ProfitabilityStrong

Operating margins hit 43.1% and FCF margins sit in the sector's top decile at 98th percentile, proving the business scales efficiently without bloating costs.

MoatStrong

Arista locks in cloud giants through its EOS software ecosystem, ranking in the top decile of its sector for operating margin and FCF margin, creating deep switching costs that rivals cannot easily bridge.

Revenue growth surges at 28.6% annually, driven by relentless demand for cloud and AI data center hardware, accelerating rapidly from historical levels.
