Fortinet, Inc. (FTNT) Cash Flow Statement

The consistent OCF/NI ratio above 1.0, except for 2024Q2 and 2024Q4 where it dipped to 0.90 and 0.91 respectively, suggests that reported earnings are well-supported by cash collections. The positive working capital changes in several quarters, such as $374.8M in 2026Q1, indicate that cash flow benefits from favorable timing of receivables and payables, but the occasional negative swings warrant monitoring for sustainability.

The FCF margin has been volatile but trended upward, with 2026Q1 at 54.4% and 2026Q2 at 47.2%, compared to the low of 17.4% in 2025Q2. This improvement is driven by robust operating cash flow and relatively modest capex, which averaged around 4-5% of revenue in recent quarters. The FCF trajectory suggests that Fortinet is converting its accelerating revenue growth into substantial cash generation, which may support further investments or shareholder returns.

Capex/Revenue ranged from 1.6% in 2024Q2 to 16.4% in 2024Q1, but recent quarters show a stabilizing trend around 3-5%, with 2026Q2 at 3.8%. This low capital intensity suggests that Fortinet's growth does not require heavy asset investment, which is typical for software infrastructure companies. The modest capex likely covers maintenance and some growth initiatives, but the low level may indicate that Fortinet can sustain high FCF margins without significant reinvestment.

The large positive working capital contributions in 2026Q1 and 2025Q1 suggest efficient collection of receivables or delayed payments to suppliers, boosting operating cash flow. Conversely, negative swings in 2025Q2 and 2024Q4 indicate cash outflows for working capital, possibly due to inventory builds or slower collections. These fluctuations are typical for a growing company but may cause quarterly cash flow volatility that investors should monitor.

The buyback activity has been substantial, with total repurchases exceeding $3B over the past five quarters, which may indicate management's confidence in the stock's value. However, the lack of dividends suggests that Fortinet is focusing on buybacks as the primary method of capital return, which can be more flexible but may not appeal to income-focused investors. The acquisitions, though smaller, also consume cash, but the overall capital deployment appears balanced with strong FCF generation.

The cumulative OCF/NI ratio of about 1.5 suggests that Fortinet's earnings quality is high, with cash flows consistently outpacing reported net income. This divergence may be attributed to non-cash charges like depreciation and stock-based compensation, but also to favorable working capital dynamics. The sustained gap indicates that Fortinet is not relying on aggressive accruals to boost earnings, which is a positive signal for investors.
