Arista CFO Sees AI Spending Cycle Nearing Third Year, Flags Later Revenue Drivers
Arista Networks CFO Chantelle Breithaupt said at a Citi conference that the AI buildout is entering its 2.5-to-3-year mark, compared with a roughly three-year cloud cycle. She noted that scale-up Ethernet products are not included in 2026 guidance and are expected to generate revenue in 2028. The company also sees campus revenue growing from $800 million in 2025 to $1.25 billion in 2026.
At a Citi conference, Arista’s finance chief placed the AI infrastructure spending wave roughly 2.5 to 3 years in, while noting the cloud buildout lasted about three years. She said scale-up Ethernet has no 2026 guidance or revenue, with management expecting that contribution in 2028. Campus sales are projected to grow from $800 million in 2025 to $1.25 billion in 2026.
In Q2, free cash flow was $1.0533 billion, missing estimates by 17.15% and falling 10.44% year over year, even as revenue rose 37.69%. The stock’s forward P/E was 44.47x, versus 20.73x for Cisco and 34.36x for Ciena. The CEO filed notice for a possible sale of 62,622 shares worth about $13.2 million.
If Arista’s longer AI networking cycle materializes, investors may reassess valuations across networking and cloud suppliers, while enterprises could face faster security and infrastructure upgrades. Workers and communities tied to data-center buildouts might see demand shifts, though timing remains uncertain. Because much of the expected revenue sits beyond 2026, near-term market reactions could stay sensitive to cash flow, guidance, and executive share sales.
