Shares of Fastly, Inc. (FSLY), a prominent U.S.-based software company specializing in edge cloud platforms and content delivery networks (CDN), plummeted more than 38% during Thursday's trading session. This sharp decline occurred despite the company reporting first-quarter earnings that surpassed expectations. The sell-off was primarily driven by its full-year revenue guidance, which signaled a significant slowdown in growth. This outlook underscores the ongoing pressure on traditional software companies' fundamental growth prospects from the "AI disruption" trend led by major AI model developers like Anthropic and OpenAI.
Despite the market's extremely pessimistic reaction reflected in the stock's plunge, most seasoned Wall Street analysts maintain a "Neutral" or more optimistic stance regarding the earnings results and Fastly's fundamental prospects. Fastly is an edge cloud platform/CDN/cybersecurity company. Its core market positioning is not that of a traditional SaaS vendor but rather a provider of "edge network infrastructure" located closer to end-users. This infrastructure accelerates the delivery of websites, apps, APIs, video, live streaming, software downloads, and dynamic content globally via edge nodes, while also offering security protection and edge computing capabilities.
Fastly's business is segmented into three main areas: Network Services, which includes CDN, application delivery, video-on-demand, live streaming, media acceleration, and API acceleration, constituting the majority of revenue; Security offerings, comprising web application firewall, bot management, API security, and DDoS protection; and Compute/edge computing and other services, allowing developers to run code on Fastly's edge nodes for real-time personalization, caching, low-latency applications, and AI-related workloads.
The company's latest earnings report showed Q1 revenue of $173 million, a 20% year-over-year increase, beating market expectations of approximately $171.8 million. Adjusted diluted EPS was $0.13, also exceeding the consensus estimate of $0.09, presenting a surface-level "beat" on both top and bottom lines. However, the company's full-year revenue guidance range of $710 million to $725 million implies a median growth rate of about 15%. Its Q2 revenue guidance of $170 million to $176 million suggests median growth of approximately 16% year-over-year. While the midpoints of these guidance ranges are largely in line with market expectations, the implied sequential slowdown from Q1's 20% growth directly dampened market enthusiasm for a potential re-acceleration driven by the "AI application traffic" narrative.
Wall Street's punitive reaction was not solely due to guidance matching or slightly missing consensus, but rather because, under the "AI disruption" thesis, the perceived strengths in Fastly's potential AI traffic and security businesses were deemed insufficient to prevent an overall annual growth deceleration. The stock's 38% drop reflects the heightened burden of proof for growth that traditional software and internet infrastructure companies face in the AI era.
A more accurate interpretation is that AI technology is not unilaterally "destroying" Fastly but is reshaping the market's valuation standards for software companies. Theoretically, Fastly could benefit from AI-driven traffic, Agentic AI, API/bot-heavy traffic, edge inference, and security demands. The company's own investor materials highlight AI-generated content, AI queries, AI inference, and Agentic AI as network traffic growth opportunities. In Q1, security revenue grew 47% year-over-year to $38.8 million, while Compute and other revenue surged 67% to $8 million. The core issue is that Wall Street is no longer willing to assign high valuations based solely on the promise of future AI-related traffic; it now demands clear evidence that this traffic is translating into accelerated core revenue growth, expanded customer commitments, and improved pricing power.
The plunge highlights the intensifying divergence among traditional software and internet infrastructure companies in the AI era. Companies that can convert AI-associated demand into verifiable revenue acceleration continue to enjoy valuation premiums, while those unable to demonstrate that their core businesses can re-accelerate driven by AI face reassessment based on a "peak growth" logic, even if they report earnings beats.
Following Thursday's close, Fastly's stock settled at $19.50, down 38.23% for the day. Analysts at Oppenheimer noted that while the company slightly raised its full-year revenue expectations, the guidance implies a gradual growth deceleration following the strong Q1 performance. They maintained a "Neutral" rating, awaiting stronger revenue and profit realization from agent AI traffic before turning more positive.
Analysts at Piper Sandler pointed to disappointment in the core delivery business, where quarterly transaction volumes fell short of expectations, and stable pricing facing tougher year-over-year comparisons. While encouraged by potential for larger minimum commitments and a possible entry into the broader "inference-as-a-service" market, they expect the stock to be weighed down by significant concerns over whether growth has peaked, especially as it still trades at a premium compared to other growth assets. Piper Sandler reiterated its "Neutral" rating and lowered its price target from $30 to $27.
RBC Capital Markets maintained its "Sector Perform" rating but reduced its price target from $20 to $18. Their analysts described Q1 as solid and expressed encouragement regarding security growth acceleration and continued profitability improvements. However, they indicated a need to see further stabilization in network services, aided by AI traffic, before adopting a more constructive bullish view.
In contrast, KeyBanc Capital Markets maintained a positive outlook, reiterating an "Overweight" rating and nearly doubling its price target from $14 to $27. KeyBanc was particularly impressed by the 47% growth in the security business segment and the 67% surge in Compute revenue, highlighting the breadth of Fastly's newer security product portfolio and strong momentum in areas like bot management and API security.
