Arista Networks reported a strong fourth quarter and raised its 2026 revenue outlook, contrasting with weaker recent performance and guidance from rival Cisco and driving a sharp rise in Arista’s share price. The company is targeting 25% revenue growth to $11.25 billion in 2026, citing surging demand for AI-related networking infrastructure, which has led analysts to adopt a more positive stance on the stock. This divergence underscores shifting competitive dynamics in data center and AI networking, with Arista currently capturing more investor confidence than Cisco.
