Fortinet Stock Closes at $175.23, Below Its $176.10 52-Week High

Key Facts

Fortinet (FTNT) closed at $175.23 on September 21, 2026, after trading between $167.41 and $175.69. The close was near the $176.10 52-week high set on September 17, but the session did not establish a new high as the original copy stated.

Fortinet raised its fiscal 2026 outlook when it reported second-quarter results on July 29. The company expects revenue of 8.02 billion dollars to 8.18 billion dollars, representing about 19% growth at the midpoint, billings of 9.35 billion dollars to 9.55 billion dollars, and adjusted earnings of 3.41 dollars to 3.47 dollars a share.

The higher outlook rested on broad operating performance, not AI alone. Revenue for the second quarter ended June 30, 2026, rose 26% to 2.05 billion dollars, product revenue increased 52% to 773 million dollars, and billings advanced 33% to 2.37 billion dollars.

Across the main demand engines, Secure Networking billings rose 34%, Unified SASE billings grew 35%, and AI-driven Security Operations billings increased 25%. Those rates show momentum spanning secure networking, SASE and security operations rather than depending on a single product.

Investors will watch whether faster billings convert into revenue and whether Fortinet delivers its targeted adjusted operating margin of 35% to 37%. Billings combine revenue with the change in deferred revenue, providing an early indicator of contracted business before it is fully recognized as revenue; any slowdown in that conversion could pressure the valuation of a stock trading near its high.
