Arista Networks Inc. (NYSE:ANET) leads in client-to-cloud networking, serving data center, campus, and AI environments with high-performance, scalable, and secure solutions. Its core platform, EOS®, enables automation, programmability, and efficiency. Arista serves major customers like Meta and Microsoft and holds leadership in high-speed Ethernet switching. Its product portfolio spans core networking, cognitive adjacencies, and cognitive software. Amid digital transformation and AI growth, Arista addresses demand with cloud-optimized architectures and AI-specific solutions, including AVA, a natural language AI tool for network operations and observability.

Rosenblatt Securities upgraded its rating on Arista Networks Inc. (NYSE:ANET) from Sell to Neutral on April 29, highlighting two main factors behind the change. Firstly, the firm noted Arista’s potential to endure a broader economic downturn, with its outlook for late 2025 and into 2026 remaining strong. Rosenblatt analyst Mike Genovese said in a note:

Following our recent field work, we now think ANET could be another such company given bigger wins at Microsoft, Oracle and Google than we previously expected. It appears that increased tariffs have actually made White Box switching options from China and rest of Asia less attractive, benefiting Arista.

The second reason is that Rosenblatt’s earlier Sell thesis has now run its course. That view was driven by worries that Arista’s Extensible Operating System (EOS) software would lose relevance within AI factory data centers.
