Revenue and billings accelerate

According to Yahoo Finance on September 22, 2026, Fortinet revenue increased 26 percent to USD 2.05 billion, while product revenue advanced 52 percent to USD 773 million. Billings rose 33 percent to USD 2.37 billion.

Higher 2026 revenue outlook

Yahoo Finance reported on September 22, 2026, that Fortinet raised its 2026 revenue outlook to USD 8.02 billion to USD 8.18 billion. The midpoint implies 19 percent year-over-year growth, while the cited Zacks consensus for 2026 earnings was USD 3.42 per share.

The operating comparison is clear: product revenue growth of 52 percent exceeded total revenue growth of 26 percent, and SASE billings growth ranged from 35 percent to more than 100 percent depending on the product line. Competition, the timing of large enterprise deals and rapid changes in artificial intelligence technology remain material factors in the outlook, according to the September 22, 2026 report.
