Fortinet reported strong third-quarter growth on October 28, 2026, and raised its 2026 outlook for revenue, billings, operating margin and non-GAAP earnings per share. The company said broad demand across its cybersecurity portfolio supported the performance.

The Fortinet investor release showed third-quarter revenue of 2.078 billion US dollars, up 20 percent from the prior-year period. Product revenue rose 37 percent to 765 million US dollars, while service revenue increased 13 percent to 1.313 billion US dollars.

Billings lead reported revenue

Total billings climbed 29 percent to 2.336 billion US dollars from 1.808 billion US dollars a year earlier. Fortinet defines billings as revenue plus the change in deferred revenue, less deferred revenue acquired in a business combination. The measure can indicate future revenue and cash generation, but it does not determine when subscription and support contracts are recognized.

For the fourth quarter, management expects revenue of 2.155 billion to 2.245 billion US dollars and billings of 2.775 billion to 2.925 billion US dollars. The full-year 2026 revenue outlook is 8.125 billion to 8.215 billion US dollars, while billings are expected at 9.568 billion to 9.718 billion US dollars.

What has changed since our last report

Fortinet stock traded at 114.22 euros on Lang & Schwarz at 16:00:47 CET on Thursday, November 12, 2026. That is 1.76 percent below the 116.27 euros cited in the relevant report published on Wednesday, November 11, at 16:59 CET.

The main investor question is whether stronger billings convert into recognized service revenue while margins and cash generation remain resilient. Chief Executive Ken Xie said Fortinet had raised its 2026 billings guidance for the third time this year.
