Approach 1: Fastly Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates a company’s value by projecting its future cash flows and then discounting them back to today’s value. This approach uses assumptions about how much cash the business will generate in upcoming years and applies a discount rate to reflect present-day worth.

For Fastly, the latest reported Free Cash Flow is $7.98 Million. Analysts predict significant growth ahead, with estimates reaching $28.8 Million by the end of 2027. Although analyst forecasts only cover the next five years, further projections out to 2035 were extrapolated to estimate longer-term performance. These projections suggest a steady increase in cash flow, with Fastly potentially generating over $88 Million annually in a decade’s time.

Based on these figures and the two-stage Free Cash Flow to Equity model, the estimated intrinsic value per share is $5.59. This reflects a 42.3% premium over the current price, indicating the stock is trading well above its fair value as implied by future cash flows.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Fastly may be overvalued by 42.3%. Discover 844 undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Fastly Price vs Sales

The Price-to-Sales (P/S) ratio is often a suitable valuation metric for companies like Fastly, especially when they are not yet profitable on a net income basis or are focused on high growth. This ratio allows investors to compare a company’s stock price to its revenues, making it easier to value firms that reinvest heavily and do not yet generate consistent earnings.

Growth expectations and risk play a key role in deciding what counts as a “normal” or “fair” P/S ratio. If a company is expected to grow faster than its rivals or operates in a less risky environment, a higher P/S ratio can be justified. In contrast, slower-growing or riskier companies typically deserve lower multiples.

Currently, Fastly trades at a P/S ratio of 2.05x. This is slightly below the IT industry average of 2.52x, and also under the peer group average of 6.95x. To provide a more tailored benchmark, Simply Wall St’s “Fair Ratio” for Fastly is 2.52x. Unlike simple peer or industry comparisons, the Fair Ratio incorporates Fastly’s specific growth prospects, profit margins, market cap and risk profile, offering a more nuanced view of what the stock should be worth.

Since Fastly’s P/S ratio of 2.05x is only marginally below the Fair Ratio of 2.52x, the stock appears to be valued about right on this basis.

Upgrade Your Decision Making: Choose your Fastly Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let’s introduce you to Narratives. A Narrative is a simple, yet powerful framework for making investment decisions, allowing you to define the story behind your assumptions about Fair Value, future revenue, earnings, and margins. Narratives connect what you believe about Fastly’s business, such as how it wins, where it grows, and what could go wrong, to realistic forecasts and a resulting fair value estimate.

With Narratives, you can see your investment viewpoint quantified and mapped to the numbers, making it much easier to decide if a stock is a buy, sell, or hold by directly comparing your Fair Value to the current price. Available to all users on the Simply Wall St Community page, Narratives are easy to create, widely used, and automatically adjust when real-world events like news or earnings change the outlook, keeping you ahead of the curve.

For example, one Fastly investor might build a bullish Narrative if they believe edge security demand and product cross-selling will drive rapid revenue growth, supporting a fair value above $10 per share. Another, more cautious investor could focus on intensifying competition and persistent losses, justifying a much lower fair value closer to $6. Narratives put your reasoning and method front and center so you can invest with clarity and confidence.
