Fortinet, Inc. (NASDAQ:FTNT) reported second-quarter 2026 results on 29 July 2026, and the figure that explains the interest is product revenue of $773.0 million, up 52% from $508.9 million a year earlier. Total revenue of $2,047.9 million rose 26%, so hardware-led product sales grew far faster than the recurring service revenue that investors usually treat as the steadier part of the model.

The company and its market

Fortinet sells network security products, led by its FortiGate firewalls, together with software and subscription services that run on them, covering secure networking, cloud security and security operations. Customers pay once for appliances and then buy renewable services such as threat intelligence updates and support.

That structure gives the group two revenue streams with different characteristics. Product revenue depends on customers refreshing equipment, which can be lumpy, while service revenue builds from the installed base and is recognised over the life of each contract. Fortinet competes in a sector that includes Palo Alto Networks, Cisco, Check Point and Zscaler, among others.

The quarter in numbers

Service revenue was $1,274.9 million, an increase of about 14% from $1,121.1 million. Billings, a measure of contracts invoiced in the period, were $2,372.1 million, up 33% from $1,778.4 million. Deferred revenue, which represents invoiced amounts still to be recognised, stood at $3,841.8 million current and $3,833.9 million non-current at 30 June 2026, against $3,636.0 million and $3,479.8 million at the end of 2025.

GAAP operating income was $689.3 million, a margin of 33.7%, compared with $458.0 million and 28.1% a year earlier. GAAP Net Income was $606.3 million against $440.1 million, and GAAP Diluted Earnings per Share were $0.82, up 44% from $0.57.

Cash generation was strong. Operating Cash Flow was $1,043.6 million and free cash flow was $965.6 million, a margin of 47.2%. Cash and investments totalled $4,468.7 million, and the company repurchased and retired $972.8 million of common stock in the six months ended 30 June 2026.

Guidance and Credit rating

Fortinet raised its full-year 2026 outlook. It now expects revenue of $8.020 billion to $8.180 billion, growth of 19%, billings of $9.350 billion to $9.550 billion, a non-GAAP Operating Margin of 35% to 37% and diluted non-GAAP earnings per share of $3.41 to $3.47. For the third quarter it guides revenue of $2.010 billion to $2.100 billion and billings of $2.250 billion to $2.350 billion. These figures are management forecasts rather than results.

The company also said Moody's had upgraded its senior unsecured notes to A3 from Baa1, a credit rating change that reflects an external assessment of its balance sheet.

Risks and uncertainties

The strength in product revenue brings its own questions. Hardware Demand is cyclical, and a surge in one period can reflect timing of customer upgrades that pulls forward spending from later quarters. Service revenue growth of about 14% is lower than product growth, so the mix may shift margins. Competition from cloud-delivered security platforms is intense, and customers can consolidate suppliers. Supply chain constraints, currency movements and changes in government or enterprise spending are further uncertainties, as is the pace at which new products convert into recurring subscriptions.

Watching the Product-to-Service Handoff

The raised guidance implies full-year revenue growth of 19%, which provides a benchmark against which each later quarter can be fairly judged by readers of the next release. The main points for the coming reports are whether product growth stays well above service growth, how billings track the third-quarter range of $2.250 billion to $2.350 billion, and whether the GAAP operating margin holds above 33%. Deferred revenue growth will indicate how much of today's product sales turns into recurring service income over time, and the pace of share repurchases will show how management uses its cash generation.
