Hook & thesis
Fastly is no longer the speculative AI darling it was in the first quarter rally. Investors are dealing that premium back after a series of headline-driven moves, creating a cleaner entry point. The company still benefits directly from two secular trends investors care about most: AI workloads moving to the edge and rising demand for edge security and compute.
My view: the market has shrunk Fastly's AI premium faster than the business can be re-rated downward. With recent quarterly traction (Q4 revenue $172.6M, Q1 record with 20% sales growth) and improving adjusted profitability, Fastly now offers asymmetric upside against a mid-sized downside. I am labeling this a Strong Buy for a long-term trade (180 trading days) with an entry at $17.50, stop at $15.00, and primary target of $26.00.
What Fastly does and why the market should care
Fastly operates a real-time content delivery network (CDN) and edge computing platform that packages delivery, security, and compute close to users. That positioning matters as AI deployments push inference and pre-/post-processing to the edge to reduce latency and cloud egress costs. Fastly's product set includes edge compute, edge delivery, edge security, and higher-value edge applications such as load balancing and image optimization.
Investors should care because the company is converting that secular demand into revenue growth and improving profitability. Two datapoints matter: management guided 2026 revenue to roughly $710M (implying mid-teens growth), and the company delivered $172.6M in Q4 2025 revenue, up 23% year-over-year. Q1 showed a record performance with 20% sales growth, while Security and Compute segments grew 67% and 47% respectively - the exact pockets of the business that capture AI and enterprise security spend.
Hard numbers and the current market snapshot
At today's price near $17.52 the company trades with a market cap of roughly $2.7B and enterprise value just north of $3.0B. Valuation multiples on the table: price-to-sales around 4.45x and price-to-book roughly 2.97x. GAAP EPS remains negative (-$0.66 reported), but adjusted metrics have flipped positive in recent quarters and free cash flow turned meaningful: reported free cash flow is roughly $46M.
Technically, the stock has pulled back from its 52-week high of $34.82 (04/08/2026) to the current range, forming a lower short-term momentum profile: the 10-day SMA sits at ~$18.90 and the 20-day SMA ~$18.20 while price is trading slightly below both. RSI at ~42 indicates room to bounce without being stretched. Short activity is elevated in recent sessions — short volume has been a meaningful share of total volume — but days-to-cover is modest, keeping the risk of squeeze limited.
Valuation framing - why $26 is reasonable
Fastly's current P/S of ~4.45x implies the market is paying for mid-to-high teens revenue growth and some margin expansion. That multiple is high for a company still losing GAAP profits, but it is not absurd for a cloud-edge infrastructure name that can sustain 15%-20%+ growth driven by AI workloads. If Fastly delivers the maturity management projects (2026 revenue guide to ~$710M) and expands adjusted margins further, moving to a 6x P/S multiple on ~$710M revenue implies an equity value north of $4.2B, translating to a share price in the mid-$20s — consistent with the $26 target. That is our bear-to-base case of continued execution plus multiple normalization back toward growth-comps that trade in the mid-single-digit P/S range when growth is steady.
Catalysts
- Continued AI-driven edge adoption: outsized growth in Security and Compute segments (recently 67% and 47%) could sustain top-line acceleration and improve pricing power.
- Quarterly beats and raised guidance: the market has punished misses harshly; confirmatory beats would force re-rating back toward peers.
- Enterprise wins and partnerships with major cloud/AI vendors can lift both revenue visibility and credibility in the AI edge narrative.
- Improving adjusted EBITDA and free cash flow: sustained positive FCF (current FCF roughly $46M) will narrow the discount for profitability risk.
Trade plan (actionable)
Primary idea: enter at $17.50 with a stop loss at $15.00 and a primary target at $26.00. The trade is sized as a long-term directional position and I expect to hold it up to 180 trading days unless either the stop is hit or the thesis materially breaks.
| Entry | Stop | Target | Horizon |
|---|---|---|---|
| $17.50 | $15.00 | $26.00 | Long term (180 trading days) |
Timing and staging: if the stock gaps below $17.00 consider using a staggered entry (two tranches) to lower cost basis. For traders with a shorter timeframe, a mid-term (45 trading days) target around $20.50 is sensible — that's a re-test of the $20 area where the 50-day EMA had been supporting the rebound. Short-term traders (10 trading days) could look for a bounce to $18.90 (10-day SMA) but should expect volatility. I recommend the primary holding period be long term (180 trading days) to allow fundamental drivers - enterprise AI wins and margin expansion - to materialize.
Technical context
Price recently slipped below short-term moving averages: 10-day SMA ~$18.90 and 20-day SMA ~$18.20. RSI (~42) shows the stock is not yet oversold, suggesting a measured recovery rather than a snap-back rally. MACD indicates modest bullish momentum (MACD histogram positive), which supports the view that the recent pullback is consolidation rather than trend reversal. Short-volume has been elevated; that creates intraday volatility but does not necessarily imply a forced squeeze given modest days-to-cover metrics.
Risks and counterarguments
- Execution risk: Fastly is still scaling higher-value services. If new AI-driven workloads fail to convert into durable ARPU uplift, revenue growth could slow below expectations.
- Valuation compression: The stock already trades at a premium P/S. Any sign of decelerating growth could force multiple compression from ~4.5x to the 2-3x range, which would put more downside pressure on the shares.
- Competition and pricing pressure: Large cloud providers and CDNs are aggressively building edge capabilities; pricing pressure or market-share loss would hurt margins.
- Macro and sector risk: a tech pullback or rotation out of growth names would likely compress Fastly’s multiple faster than fundamentals change.
- Insider selling headline risk: CEO stock sales (notably on 03/11/2026 under a 10b5-1 plan) can trigger short-term sentiment drops even if the sales are pre-planned and not indicative of long-term views.
Counterargument - the bull case is partly priced in: the stock tripled over the prior year and at a ~4.5x P/S investors have already paid for a lot of the 'AI edge' growth. If AI momentum cools or peers deliver faster execution, Fastly could underperform. That said, the current pullback puts downside closer to $15 while $26 remains achievable if management hits guidance and margins expand.
Why this trade - balanced view
This is a risk/reward play. The company is showing the right kind of revenue mix (strong growth in Security and Compute) and improving cash generation. The market has punished the stock for short-term growth misses and headline volatility; that has reduced the immediate premium and created a more attractive entry point. The stop at $15 limits downside to a level that would likely reflect either a serious derating or material slowdown in the AI-driven revenue pickup.
What would change my mind
I will re-evaluate the thesis if any of the following occur:
- Management lowers guidance materially below the mid-teens growth implied by the $710M 2026 target.
- Security or Compute segment growth falls back to low-single digits sequentially, indicating demand weakness for AI edge workloads.
- Free cash flow reverses meaningfully and adjusted profitability deteriorates.
- Major competitive contract losses to hyperscalers that materially reduce TAM capture.
Bottom line
Fastly is a high-conviction buy here for investors willing to tolerate execution and headline risk. The pullback has shrunk the AI premium and created a measured entry around $17.50 with reasonable upside to the mid-$20s if the company executes on its edge/AI growth narrative and continues to improve margins and FCF. Keep sizing sensible, use the $15 stop to control downside, and allow the story to play out over the next 180 trading days.
