Approach 1: Fortinet Discounted Cash Flow (DCF) Analysis
A Discounted Cash Flow, or DCF, model estimates what a company could be worth by projecting its future cash flows and then discounting those back to today’s value. It is essentially asking what a stream of future cash in today’s dollars might be worth.
For Fortinet, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The company’s latest twelve month free cash flow is about $2.23b. Analyst and extrapolated estimates in this model point to free cash flow reaching around $3.98b by 2030, with a series of yearly projections between 2026 and 2035 provided and discounted back to today using Simply Wall St’s assumptions.
Putting those discounted projections together, the DCF output suggests an estimated intrinsic value of about $100.62 per share. Compared with the recent share price of $84.34, the model indicates the stock is around 16.2% undervalued.

Approach 2: Fortinet Price vs Earnings
For profitable companies, the P/E ratio is a useful way to see how much investors are willing to pay for each dollar of earnings. It ties the share price directly to current profitability, which many investors treat as a core anchor for value.
What counts as a “normal” P/E often comes down to two things: how quickly earnings are expected to grow and how risky those earnings are. Higher expected growth or lower perceived risk can justify a higher multiple, while slower growth or higher risk usually points to a lower one.
Fortinet currently trades on a P/E of 33.67x. That sits above the wider Software industry average of 30.50x, but below the peer group average of 49.62x. Simply Wall St’s Fair Ratio for Fortinet is 30.91x, which is a proprietary estimate of what the P/E might be based on factors such as earnings growth, industry, profit margins, market cap and risk profile. Because it blends these company specific inputs, the Fair Ratio can be more informative than a simple comparison with peers or the broad industry average.
Compared with this Fair Ratio, Fortinet’s current P/E of 33.67x is higher, which points to the shares trading at a premium.
Result: OVERVALUED

🐂 Fortinet Bull Case
Fair value in this bullish narrative: US$99.03 per share
Current price vs this fair value: about 14.8% below the narrative fair value
Revenue growth assumption used in this narrative: 12%
- Emphasis on Fortinet’s GAAP profitability, with operating and net margins above 30% and a business model built on organic growth rather than large acquisitions.
- Highlights a current P/E around 40x TTM earnings, framed as lower than the 10 year historical average P/E of 140x, so the stock is described as cheaper relative to its own history.

Fair value in this bearish narrative: US$68.00 per share
Current price vs this fair value: about 24.1% above the narrative fair value
Revenue growth assumption used in this narrative: 9.32%
- Focuses on Fortinet’s hardware centric mix and argues that growing preference for cloud native security and platform consolidation could pressure pricing power and long term revenue growth.
- Assumes margins ease over time and applies a future P/E of about 25.3x to earnings that bearish analysts expect by 2029, using an 8.5% discount rate to frame a fair value near the lower end of analyst targets.
- Points to higher compliance costs, competition in unified threat intelligence, and potential customer churn if rivals with stronger AI, identity, and endpoint integration gain share.
