- note: 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.
