Approach 1: Fortinet Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates a company's intrinsic value by projecting its future cash flows and discounting them to today's value. This helps investors determine whether a stock is trading above or below its true worth.

For Fortinet, the current Free Cash Flow stands at $2.10 billion. Analyst projections anticipate strong growth, with Free Cash Flow estimated to reach around $3.59 billion by the end of 2029. Looking even further, Simply Wall St extrapolates Fortinet's cash flows to just under $4.76 billion in 2035. It is important to note that estimates beyond five years are less certain.

Using a two-stage Free Cash Flow to Equity approach, the intrinsic value of Fortinet shares is calculated to be $88.53. This figure suggests the stock is trading at an 8.4% discount to its intrinsic value, indicating it is almost fairly valued at current price levels and within a reasonable margin of error.

Result: ABOUT RIGHT

Fortinet is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: Fortinet Price vs Earnings

The Price-to-Earnings (PE) ratio is the preferred valuation metric for Fortinet because it is a profitable company with a solid track record of generating earnings. The PE ratio allows investors to gauge how much they are paying for each dollar of earnings, making it especially useful for analyzing businesses that consistently generate profits.

Not all PE ratios are created equal. Growth expectations and risk profile play critical roles in determining what qualifies as a “normal” or fair PE for a particular stock. Companies with higher expected earnings growth or lower perceived risks typically command higher PE ratios, while slower-growing or higher-risk firms trade at a discount.

Currently, Fortinet trades at a PE ratio of 32.2x. This is slightly above the Software industry average of 31.8x, but well below the average for direct peers, which stands at 66.1x. Rather than simply using these simple comparisons, Simply Wall St's proprietary "Fair Ratio" takes things a step further. The Fair Ratio considers specifics like Fortinet’s earnings growth, profit margins, sector characteristics, company size, and risk exposure, and estimates a fair PE for Fortinet to be 36.1x.

This Fair Ratio approach is a more nuanced benchmark than industry or peer comparisons, as it is tailored to the unique aspects impacting Fortinet’s valuation. In this case, Fortinet’s current PE ratio is within a reasonable margin of its Fair Ratio, suggesting that the stock is trading at close to its justified level based on fundamentals.

Upgrade Your Decision Making: Choose your Fortinet Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives. A Narrative is a clear, simple story investors create about a company’s future, linking their perspective on factors such as revenue growth, profit margins, and risks directly to fair value estimates. This approach turns financial forecasts into a coherent investment thesis. On Simply Wall St's Community page, millions of investors already use Narratives as an easy tool to express their view and track whether a stock like Fortinet is undervalued or overvalued, based on their own assumptions.

Narratives make it straightforward to decide on your investment stance, since you can instantly see how your fair value calculation compares with the current share price. As news or earnings are released, the platform dynamically updates all Narratives, keeping you current without extra effort. For example, with Fortinet, some investors’ Narratives calculate as much as $99 per share based on high revenue growth and profitability, while the most cautious see fair value closer to $67. This demonstrates how the Narrative approach helps you compare differing viewpoints that are grounded in real numbers.
