Approach 1: Fastly Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a company could generate in the future and discounts those back to today to arrive at an estimate of what the business might be worth right now.

For Fastly, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $31.29 million. Analysts provide free cash flow estimates out to 2027, with Simply Wall St then extending those cash flows further using its own assumptions. The ten year projections show discounted free cash flows each year, ending with a discounted figure of about $28.62 million in 2035.

Pulling all those discounted cash flows together gives an estimated intrinsic value of around $5.43 per share. Compared with the recent share price of US$8.57, the model implies Fastly is about 57.9% overvalued on this DCF view.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Fastly may be overvalued by 57.9%. Discover 53 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Fastly Price vs Sales

For companies where earnings are limited or volatile, the P/S ratio is often a useful way to think about value because it compares what investors pay for each dollar of revenue instead of profits that can swing around.

Growth expectations and risk both matter here. Higher expected growth or lower perceived risk can justify a higher P/S multiple, while slower expected growth or higher uncertainty tend to support a lower, more conservative range.

Fastly currently trades on a P/S ratio of 2.16x. That sits close to the wider IT industry average of 2.02x and below the peer group average of 4.42x. Simply Wall St also provides a proprietary “Fair Ratio” for Fastly of 2.37x, which reflects factors such as the company’s growth profile, profit margins, industry, size and key risks, rather than just a simple comparison with industry or peers.

This Fair Ratio can be more tailored than a straight peer or sector check, because it ties the multiple to company specific characteristics instead of assuming that all IT names deserve similar pricing.

Comparing Fastly’s current 2.16x P/S to the 2.37x Fair Ratio suggests the shares screen as undervalued on this metric.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Fastly Narrative

Earlier we mentioned that there is an even better way to understand valuation. Let us introduce you to Narratives, which are simply your own story about a company, tied directly to numbers like fair value, future revenue, earnings and margins.

On Simply Wall St, Narratives live in the Community page and give you a clear link between Fastly’s business story, a forecast you are comfortable with and the fair value that drops out of those assumptions.

You can then compare that fair value to the current share price to help decide whether you think Fastly looks attractive, fully priced or expensive based on your view, instead of relying only on headline multiples.

The powerful part is that Narratives update as new information such as earnings or news is added to the platform. This means your view on Fastly can stay current without you rebuilding your forecast from scratch.

For example, one Fastly Narrative on the Community page might assume a relatively high fair value based on optimistic revenue growth and improving margins. Another Narrative might point to a lower fair value built on more conservative growth and profitability assumptions.
