StockStory’s take

Fastly’s third quarter results were highlighted by revenue and non-GAAP profit both coming in well above Wall Street expectations. Management attributed outperformance to the continued expansion of its largest customers and accelerated adoption of security and AI-focused products. CEO Kip Compton highlighted that 74% of large customers now use two or more product suites, and 34% are adopting four or more, up from 30% last quarter. The company credited recent wins in the AI and media sectors, alongside broader success in cross-selling, as central to the quarter’s performance.

Looking forward, Fastly’s elevated guidance reflects management’s confidence in continued platform adoption, especially as enterprise AI moves into large-scale production. The company is focused on expanding its security portfolio and driving further cross-sell opportunities, with new offerings like AI Runtime Control and AI Firewall set to address evolving customer needs. CFO Rich Wong noted that operating leverage and disciplined capital allocation will underpin profitability, while Compton emphasized, “The breadth of our platform and relationships built on trust allow us to solve those challenges, and that is how we grow with our customers.”

Key insights from management’s remarks

Management pointed to outsized growth from large customers, rapid multi-product adoption, and a strong pipeline of AI and security solutions as primary drivers of both the quarter’s success and Fastly’s outlook.

• Large customer expansion: Fastly’s biggest customers drove the majority of revenue gains, with top 10 accounts growing 46% year-over-year. Management emphasized that engagement with these clients remains a primary source of strength, but acknowledged that growth among smaller customers has lagged, reflecting an intentional focus on where performance matters most.
• Multi-product adoption: The proportion of large customers using four or more product suites rose to 34%, more than tripling from two years ago. Management views this as a key indicator of “stickiness” and future upsell potential, noting that broader product adoption directly supports long-term revenue durability.
• AI and security momentum: Fastly landed a seven-figure deal with a major AI company to secure agentic (AI-driven) traffic and launched new products such as AI Runtime Control and AI Firewall. Leadership believes that rising AI adoption and new web security threats are increasing demand for advanced edge security solutions.
• Go-to-market transformation: The company’s shift toward a unified platform and strategic investments in international expansion, partnerships (notably with Comcast), and revamped marketing are starting to yield results. However, management recognized that benefits for segments outside the top 10 customers will take longer to materialize.
• Leadership transition risk: President of Go-to-Market Scott Lovett’s planned retirement introduces uncertainty around sales execution. Management is conducting an internal and external search for a new Chief Revenue Officer, with Lovett remaining through the transition to ensure continuity.

Drivers of future performance

Fastly’s guidance is anchored in expanding enterprise AI workloads, continued security product growth, and platform adoption, but faces execution risk as the company transitions key sales leadership.

• Enterprise AI adoption: Management expects enterprise AI workloads to scale further, driving both delivery and security revenue. New security products for AI governance are designed to capture emerging demand as businesses deploy AI at the edge, though the revenue impact will depend on broader industry adoption.
• Security cross-sell and product launches: Fastly is banking on continued momentum from its security suite, particularly Bot Management and DDoS solutions, to increase share of wallet among existing customers. The company sees cross-sell opportunities expanding as more customers adopt multiple product suites, but acknowledges competition and evolving customer needs as ongoing risks.
• Go-to-market transition and customer mix: While top customer growth has powered recent results, management recognizes that growth among smaller customers has slowed. Investments in marketing, international expansion, and partnerships are ongoing, but the upcoming change in sales leadership introduces uncertainty around execution, especially in broadening growth beyond the largest accounts.

Catalysts in upcoming quarters

Looking ahead, the StockStory team will monitor (1) the pace of multi-product adoption among both large and smaller customers, (2) execution of the go-to-market transformation as the new sales leader is appointed, and (3) the scaling and monetization of new AI-focused security products. The impact of key partnerships, such as with Comcast, and traction in international markets will also be important signposts.

Fastly currently trades at $17.62, down from $21.30 just before the earnings. In the wake of this quarter, is it a buy or sell? See for yourself in our full research report (it’s free).
