Fastly (FSLY) presents a moderate upside opportunity for a job seeker.

Last updated: March 10, 2026

Bull (20%)+90%

Fastly's security segment, powered by Signal Sciences technology, continues its accelerated growth (32% in Q4 2025), driven by strong demand for WAAP and API security, and further boosted by AI-related traffic tailwinds. This leads to sustained overall revenue growth above 20% and significant improvements in GAAP profitability, pushing its P/S multiple to 8x-10x, resulting in a market cap of $5.5B - $6.5B within two years.

Base (40%)+25%

Fastly maintains its position in the edge cloud and security markets, growing overall revenue in line with its 2026 guidance (14% YoY) and continuing to narrow GAAP losses while remaining non-GAAP profitable. The company's market cap grows modestly to $3.6B - $4B, reflecting steady execution against intense competition.

Bear (40%)-40%

Intense competition from hyperscalers and larger security vendors like Cloudflare and Akamai puts pressure on pricing and market share, causing Fastly's overall revenue growth to decelerate below 10% and delaying GAAP profitability. Customer concentration risks also materialize, leading to a contraction in its valuation multiple to 3x-4x, resulting in a market cap of $1.8B - $2.5B and a significant decline in equity value.

Questions to Ask at the Interview

Strategic questions based on Signal Sciences's data — designed to show you've done your homework.

  • 1

    “How is Fastly planning to differentiate its security offerings, particularly those derived from Signal Sciences, against the bundled solutions from hyperscalers and established security vendors like Cloudflare and Akamai?”

  • 2

    “Given the strong Q4 2025 revenue growth of 23% but a full-year 2026 guidance of 14% at the midpoint, what are the key factors influencing this projected deceleration, and what strategies are in place to re-accelerate overall growth?”

  • 3

    “Fastly achieved non-GAAP profitability in FY2025 but still reports GAAP net losses. What is the company's timeline and strategic path to achieving sustainable GAAP profitability, and how might this impact employee equity value?”
