Fastly (FSLY) Beat Expectations And Lifted Guidance, Is The Upside Already Priced In?
Fastly (FSLY) drew investor attention after its latest earnings report showed adjusted earnings and revenue above expectations, with raised 2026 guidance tied to AI demand and broader adoption of its edge cloud platform.
The recent pullback in Fastly’s share price, including a 1-day share price return of down 2.5% and a 30-day share price return of down 20.9%, comes after a strong run that left the year-to-date share price return at 102.1% and the 1-year total shareholder return at 177.1%. This suggests recent earnings and AI commentary are being weighed against an already strong move and changing views on future risk and reward.

Most Popular Narrative: 23.7% Undervalued
Fastly last closed at $20.59, while the most widely followed narrative anchors fair value at $27.00. That gap is built on specific expectations for security and compute workloads and a detailed cash flow path using a 9.5% discount rate.
The acceleration of cloud migration and edge computing, combined with Fastly's increased product velocity (especially in Compute and adaptive observability analytics at the edge), expands the company's addressable market and underpins durable multi-year revenue growth.

Another View On Fastly Using Market Ratios
While the most popular Fastly narrative points to a fair value of $27.00, the market ratio picture looks less generous. Fastly trades on a P/S of 4.8x compared with a US IT industry average of 1.9x and a fair ratio estimate of 3.8x. That means the stock is pricing in richer sales expectations than both the sector and the fair ratio imply. The question for you is whether Fastly’s growth and margin path justify paying that kind of premium today.
