Arista Networks reports strong quarterly earnings, maintaining buy thesis on sustained data center networking demand.

Arista Networks continues to deliver robust earnings, consistently beating expectations by 10–15% and justifying its premium valuation. The company benefits directly from the hyperscaler capex supercycle, with cloud giants' spending driving strong revenue and earnings growth through at least 2027.

When Arista was upgraded to a buy last August, the decision was made fully cognizant that this was a high multiple stock that would have little choice but to continue landing big earnings numbers—and that bet has continued to pay off.

Despite a headline P/E multiple of 40x, the company's PEG ratio remains mid-range, and true forward multiples may be closer to 35x given persistent outperformance. A buy rating is maintained, as hyperscaler demand, supply constraints, and future refresh cycles underpin a durable growth runway for ANET.
