FSLY +91% in February: The Earnings Blowout Signals AI Tailwinds – But Is It Sustainable?
Fastly (FSLY) just delivered a monster Q4 2025 earnings report on February 11, with revenue hitting $172.6M (up 23% YoY and beating consensus by \~$11M), non-GAAP net income flipping to positive $20.1M (from a loss last year), and full-year 2026 guidance at $700-720M revenue (14% midpoint growth, well above Wall Street's $668M estimate). The stock exploded +72% in a single day post-earnings, pushing its February gains to \~91% – making it the top monthly performer so far in 2026. For context, that's outpacing even NVDA's recent moves, while peers like Cloudflare (NET) are up only \~15% this month.
The market reacted positively (stock now at \~$16, a 2-year high), but this divergence is fascinating. On one hand, investors are endorsing Fastly's edge computing and security pivot – network revenue up 19%, security surging 32% – amid growing AI demand for faster data delivery. CEO Kip Compton called it an "inflection point," highlighting AI as a key tailwind for 2026, which aligns with broader tech trends like hyperscaler expansions. On the other, it raises questions about over-optimism: valuation now at \~6x forward sales (elevated for a SaaS player with flat EPS growth expected at $0.17 for 2026), and analysts like Citi/DA Davidson recently cut PTs to $9-10 pre-earnings due to competitive pressures in cloud infrastructure.
I'm neither all-in nor sitting out here, but this level of euphoria around such massive growth makes me cautious. Historically, when the market heavily rewards large-scale investments without immediate profitability (Fastly's first positive FCF year), it can set precedents for later re-evaluations – think back to the 2021 cloud hype cycles where similar beats led to 50%+ pullbacks. Apart from that, January-February 2026 is shaping up as a triple-threat moment:
* Risk of economic slowdown with persistent inflation.
* AI/hardware stocks breaking historical levels amid chip shortages.
* Major Big Tech earnings colliding in the same window, forcing rotations.
Why the market is reacting this way
Political/economic uncertainty has weakened the dollar, but that's secondary here – the real driver is capital shifting toward pure AI enablers. Software is getting cheaper to scale, but the hardware powering AI is becoming more expensive, forcing a re-evaluation of edge players like FSLY who optimize data flows.
Personally, this kind of announcement makes me uneasy. I've seen past cycles where the market celebrated massive CAPEX long before returns materialized (e.g., early AWS builds). With Fastly narrowing losses by 23% to $121.7M in 2025, it's progress – but a +91% move isn't yet proof that $700M+ revenue will translate to real shareholder value.
What bothers me with FSLY today isn't just the size of the investments, but the timing – the market is rewarding the story before the economics are fully proven.
A +91% monthly move is impressive, but it's not yet proof that this will translate into real shareholder value.
For me, the more sensible approach right now is to stay defensive, focus on the short term (both long and short), and only scale exposure when clearer "green lights" start to appear.
That's why I still find Bitget Stock Futures particularly interesting this week (easy long and short exposure, leverage to improve capital efficiency).
How do you read this situation?
* Are you increasing your exposure to FSLY following this momentum and guidance?
* Are you trimming or staying neutral, waiting for more visibility on the ROI of these AI investments?
* Or are you simply observing the divergence with the other Big Tech names?
I'm curious about your takes, especially on how you assess the sustainability of this capex level in the current context (interest rates, ad growth, competition).
Let's discuss calmly and factually.
