Fortinet’s Valuation in Focus After New AI-Powered Security Product Launch

Thinking about what to do with Fortinet stock right now? You are not alone. With all the buzz around cybersecurity and the constant stream of headlines, it is fair to wonder if the company’s best days are already baked into its price or if this is an opportunity others are missing.

Let’s look at the numbers for a moment. Fortinet just closed at $84.92. In the past week, the stock moved up 1.0%, and it has seen a solid 7.7% gain over the last 30 days. That is not bad, especially given that its year-to-date return is down 10.4%. If you zoom out a little further, the story changes: over the last year, Fortinet is up 9.2%, and in the past five years it has delivered a remarkable 225.1% return. Those long-term gains underscore the market’s belief in cybersecurity as a driver of future growth, despite any bumps along the way. Some of this recent optimism may relate to broader market developments, including renewed focus on digital protection as companies expand their remote networks and regulations push organizations to strengthen security.

If you are looking for a quick snapshot, Fortinet currently has a valuation score of 4 out of 6 possible checks for being undervalued. That means it clears the bar in most of the key assessments analysts use. But what does that really mean in the context of today’s market, and is it enough to justify making a move now? Up next, let’s dig into the major valuation methods and, later on, explore a smarter way to cut through the noise to decide if Fortinet belongs in your portfolio.

Why Fortinet is lagging behind its peers

Approach 1: Fortinet Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) model works by projecting Fortinet’s future free cash flows and discounting them back to what they would be worth in today’s dollars. This approach is useful for figuring out the true, intrinsic value of a company, based on its expected ability to generate cash over time.

Currently, Fortinet’s free cash flow stands at $2.05 Billion. Analysts estimate that free cash flow could rise to $3.54 Billion by 2029. While analysts provide detailed estimates out to five years, projections further out are extrapolated based on trends. Over the next decade, free cash flows are expected to see healthy growth, which supports the robustness of the company’s business model in software and cybersecurity.

The result of this DCF analysis is an estimated intrinsic value of $85.12 per share. That figure is almost exactly in line with Fortinet’s current closing price of $84.92. According to the DCF, the stock trades at a 0.2% discount to its inherent value, suggesting it is fairly priced relative to its future cash flow expectations.

Approach 2: Fortinet Price vs Earnings

For profitable companies like Fortinet, the price-to-earnings (PE) ratio is one of the most widely used valuation metrics. The PE ratio shows how much investors are willing to pay for $1 of the company’s earnings, which makes it a straightforward way to assess whether the stock appears expensive or cheap compared to others in the market.

Expectations for future growth and a company’s risk profile play a crucial role in determining what a "normal" or fair PE ratio should be. High-growth and lower-risk businesses usually command higher PE multiples, reflecting hopes for rising profits and stability.

Fortinet currently trades at a PE ratio of 33.5x. That sits just under the software industry’s average PE of 35.6x and well below the average of its peer group at 72.7x. On the face of it, the stock does not look especially expensive or cheap when compared to broad sector benchmarks.

To get a more tailored perspective, we can look at Simply Wall St’s proprietary “Fair Ratio” for Fortinet, which factors in unique aspects like earnings growth, profit margins, industry positioning, company size, and risks. This “Fair Ratio” assigns Fortinet a multiple of 35.9x, slightly above its current PE. Because the Fair Ratio uses a holistic approach, it is more insightful than simply comparing against industry or peer averages, which may overlook important company-specific details.

With Fortinet’s current PE ratio of 33.5x just below its Fair Ratio of 35.9x, the stock appears to be valued about right by this measure.

Upgrade Your Decision Making: Choose your Fortinet Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let’s introduce you to Narratives. A Narrative is more than just financial data; it is the story and logic you believe about a company, made tangible by your assumptions around future revenue, earnings, and margins. Narratives connect your view of Fortinet’s business direction to specific financial forecasts and, ultimately, to an estimated fair value.

On Simply Wall St’s Community page, Narratives are easy to create and compare, making investing more accessible for everyone. They let you see at a glance whether your view (or any other investor’s) suggests the stock is undervalued or overvalued by lining up Fair Value with today’s Price. Since Narratives are dynamic, they update as soon as new news, earnings, or forecasts are released.

For example, some investors expect robust recurring growth and see Fortinet’s Fair Value as high as $120, while others are more cautious and estimate only $67. Narratives empower you to understand why perspectives differ and make better, more confident decisions about when to buy, hold, or sell.
