Why We're NOT Buying Fastly (Even at 22% Growth)

Fastly's revenue just re-accelerated into the mid-20% range — but our reverse DCF says the stock still needs 22%+ FCF growth for a decade to justify $26. Here's why that's a hard pass for now.

Part 3 of our CDN series puts Fastly under the microscope after comparing it against Cloudflare and Akamai. We walk through our full investment thesis checklist — supply chain position, technology stickiness, revenue model, and capital structure — before running a reverse DCF on Fastly's free cash flow per share.

Revenue growth has re-accelerated, and operating margins are improving, but GAAP profitability still lags Cloudflare, stock-based compensation remains elevated relative to revenue, and share dilution is running well above our target threshold. We also look at customer stickiness — including the loss of a major account to Cloudflare — as a proxy for platform depth and competitive moat.

The result: Fastly lands on our watchlist rather than our buy list, with a price level flagged for renewed interest if shares pull back meaningfully. We close the series by connecting CDN infrastructure to the broader AI infrastructure buildout, and how a small CDN/cybersecurity basket — anchored by Cloudflare — fits inside a semiconductor and infrastructure-focused portfolio.
