On September 22, Fortinet rose 3.09% in regular trading, trading at approximately $175.08 per share, with turnover of $2.91 billion. The rally was driven by escalating AI security concerns that lifted the broader cybersecurity sector.

On the news front, Anthropic CEO Dario Amodei recently published a lengthy essay calling for a slowdown in advancing frontier AI model capabilities, warning that AI agents' attack capabilities are improving rapidly and could potentially cause hundreds of billions of dollars in losses. The heightened threat narrative fueled strong demand across cybersecurity names, with sector peer CrowdStrike surging 5.26% and Palo Alto Networks climbing 2.33% during the same session.

Fortinet's fundamentals also provide underlying support. The company's most recently reported second-quarter results exceeded expectations, prompting management to raise full-year revenue guidance to $8.02 billion to $8.18 billion, representing approximately 19% year-over-year growth. Following the earnings beat, multiple investment banks — including Cantor Fitzgerald, Evercore ISI, and JPMorgan — raised their price targets on the stock, with the consensus mean target standing at approximately $137.
