Approach 1: Fastly Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting its future cash flows and discounting them back to today using a required return. It is essentially asking what all future cash generated by the business is worth in present dollar terms.

For Fastly, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow is about $31.3 million. Analyst inputs and Simply Wall St extrapolations project Free Cash Flow rising to $37.7 million in 2026, $44.4 million in 2027 and around $73.3 million by 2035, all in $ terms. Each of those future cash flows is discounted back, then summed to arrive at an estimated intrinsic value per share.

On this basis, the DCF fair value for Fastly is calculated at about $5.28 per share. Compared with the recent share price of $10.53, the model implies the stock is 99.5% overvalued, so the cash flow assumptions used here do not currently support the market price.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Fastly may be overvalued by 99.5%. Discover 885 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 you pay to the revenue the business is already generating.

What counts as a “normal” P/S depends a lot on how quickly investors expect that revenue to grow and how risky they think the business is. Higher growth and lower perceived risk tend to support higher multiples, while slower growth or higher uncertainty typically point to lower ones.

Fastly currently trades on a P/S of 2.66x. That sits above the IT industry average P/S of 2.37x and below a peer group average of 3.19x. Simply Wall St’s Fair Ratio for Fastly is 2.62x. This is its proprietary estimate of what the P/S should be once you factor in elements like earnings growth, margins, the company’s industry, market cap and risk profile. This tailored Fair Ratio can often be more informative than a simple comparison to peers or the broad industry, because it adjusts for Fastly’s own characteristics rather than assuming it should match a generic average.

With the current P/S at 2.66x and the Fair Ratio at 2.62x, the valuation looks very close to that custom estimate.
