Arista Networks continues to benefit from AI-driven growth but faces competitive pressure from Celestica and other white-box Ethernet switch suppliers. Celestica is described as benefiting from rising demand for white-box Ethernet switches, with faster expected revenue growth and greater potential for margin expansion. Arista is prioritizing supply security rather than passing higher supply-chain costs to customers, which may constrain its competitive margin position.
