The tech networking equipment specialist's equity, which has done well over the past few years thanks in no small part to its involvement in artificial intelligence (AI) capability build-out, rose by nearly 6% across that trading session. Attracting the heavyweights That analyst, Rosenblatt's Mike Genovese, upgraded his Arista recommendation before market open that day. He flagged it as a buy, one notch above his previous neutral rating, and set a price target of $180 per share. Image source: Getty Images. Genovese waxed optimistic in his update about Arista's work with AI hyperscalers, according to report. He wrote that the company's recently introduced extra-dense pluggable optics (XPO) strategy, centered around its state-of-the-art optical modules used in such facilities, is helping to make it very competitive in the AI infrastructure space. Effectively managed, the pundit believes this approach can maintain the business of deep-pocketed clients such as Microsoft and Meta Platforms. With that, Arista has the potential to grow its annual revenue by nearly 40% both this year and next, well exceeding management's guidance.

Ultimately, there aren't a great many qualified equipment makers specifically targeting the AI niche, so while Genovese's projections might look lofty at first glance, they're probably realistic.
