Investments

  • Share repurchases (capital allocation) High confidence· gross margin 64.1% · FY2025
    Arista returns free cash flow via stock repurchase programs — a capital-allocation structure that deploys cash built up in the AI-switching boom (FY2025 revenue $9.0B, 64.1% gross margin) into buybacks alongside growth investment (R&D, M&A). With a net-cash, no-dividend stance, buybacks are the primary return mechanism.

YTD as of 2026-07-10 · source: Yahoo Finance

Arista Networks operates across AI datacenter Ethernet switches. Momentum stayed firm and it is +41% in 2026. The supply side (avg +101.5%) has moved harder than the stock (+41%). That is the classic bottleneck pattern: supplier volume leverage is being priced before this layer's own margin. Among connected nodes the furthest ahead is Marvell (+186.6%) and the furthest behind is Microsoft (-20.2%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. Depends on Broadcom (Tomahawk/Jericho) for switch silicon; Meta built AI clusters on the 7700R4.
