What it stands on, and what could break it

What the business leans on

1A small number of customers account for substantial sales: one customer represented 26% of revenue (fiscal year ended December 31, 2025, high), and another represented 16% of revenue (fiscal year ended December 31, 2025, high).
2Arista relies primarily on Broadcom for switching chips, and some important components come from a limited number of suppliers or sole-source suppliers.
3Arista uses outside manufacturers to build most of its products. Its purchase obligations were $9.7 billion (June 30, 2026, high), including non-cancellable commitments for products and components.

What could go wrong

1Large customers can change the timing or size of orders, and their purchases make up a substantial share of revenue. Arista says order timing can vary with customer spending plans, product deployments and testing.
2Shortages or delays in chips, memory and other components can hold up shipments or raise costs. Large purchase commitments also leave Arista exposed if customer demand or product requirements change.
3The networking market changes quickly. Customers may choose competing systems, including white-box equipment, or use alternatives such as InfiniBand or NVIDIA's NVLink for AI computing networks; Arista could lose sales if its products do not meet changing customer needs.
