However, this strong performance report did not boost its stock price. After the financial report was released, the company's stock price slipped in after-hours trading and continued to fall in the next day's trading, with a decline of over 8%.

William Blair analyst Sebastien Naji wrote in a research report that Arista management believes 'we are still in the early stages of the big trend of AI'.
