On May 22, Arista Networks rose 3.02% in regular trading, trading at $153.12/share, with trading volume of $413 million, extending its recent rebound momentum.

The rally was driven by multiple catalysts. The company reported strong first-quarter results, with both revenue and earnings per share beating expectations. More notably, management raised its full-year revenue guidance and significantly elevated its AI business revenue target to $3.5 billion, implying AI sales could double year-over-year. The company's focus on AI-driven infrastructure solutions, including XPO high-density liquid-cooled pluggable optical modules and the 7800 AI backbone architecture, positions it favorably in the rapidly expanding AI infrastructure market.

Additionally, recent analyst upgrades provided valuation support. Raymond James upgraded the stock from Market Perform to Outperform with a $164 price target, while Rothschild&Co Redburn raised its target to $179.15 maintaining a Buy rating. The consensus mean target stands at $188.18, suggesting meaningful upside from current levels despite earlier concerns over Q2 margin guidance.
