Business Overview
Fastly operates a global edge cloud platform that delivers content, accelerates applications, and secures digital experiences for enterprises. The company generates revenue primarily through usage-based fees for network services (content delivery), security products (such as web application firewall, DDoS protection, and bot management), and compute (edge computing solutions). Major segments include Network Services, Security, and Compute/Other, with increasing focus on security and compute as growth drivers.
Performance Analysis
Q1 2026 results highlight a decisive pivot toward higher-value product lines. Security revenue climbed 47% year-over-year, now accounting for 22% of total sales. Compute and other offerings posted 67% growth, representing the largest sequential revenue step-up in this category to date. Combined, these segments delivered 50% growth and are on track to surpass a $200 million annual run rate by late 2026.
Network Services, Fastly’s legacy CDN (content delivery network) business, grew 11% year-over-year—approximately double the market’s pace, though below some expectations due to strong Q4 seasonality and a normalization of gaming and e-commerce traffic. Gross margin reached a record 65.1%, aided by platform efficiency and a one-time accounting benefit, while operating margin swung to positive territory, reflecting improved cost discipline and scale leverage.
- Security Portfolio Expansion: Newer products (DDoS, bot management, API tools) are now landing with new customers and driving cross-sell, broadening Fastly’s addressable market.
- Compute Momentum: Edge compute demand is rising, fueled by AI and agentic workloads, with design partner collaborations accelerating product-market fit.
- Customer Mix and Retention: Large customer count (>$100K ARR) reached 634, with net retention climbing to 113%—now increasingly driven by mid-market adoption.
RPO (remaining performance obligations) surged 63% year-over-year to $369 million, with 75% of that recognized within 12 months, signaling robust forward visibility and larger upfront commitments.
Executive Commentary
"Security growth accelerated 47% year over year and represented 22% of our total revenue. Our industry-leading WAF continues to perform well, and we're also seeing increasing momentum across our portfolio. In fact, among instances of security products sold to new customers in the quarter, almost half were of our newer products, DDoS protection, bot management, and API discovery and inventory."
Kip Compton, Chief Executive Officer
"Our incremental gross margin flow through on a trailing 12 month basis increased to 89% in the first quarter, up from 54% a year ago... This is demonstrated by our operating margin expanding from negative 4% to positive 11% in the first quarter, an expansion of approximately 1,500 basis points year over year."
Rich Wong, Chief Financial Officer
Strategic Positioning
1. Security Suite Drives Platform Expansion
Fastly’s security portfolio has evolved from a single product (WAF) to a diversified suite including DDoS, bot management, API discovery, and ContentGuard. This breadth is enabling new customer wins and deeper penetration with existing clients, especially as AI-driven threats and privacy concerns intensify. The company is now landing multi-product security deals, not just upselling to its installed base.
2. Edge Compute and AI Opportunity
Edge compute revenue is accelerating as customers seek to run AI inference and agentic workloads closer to users. Fastly’s programmable, distributed network is well-positioned for these next-gen workloads, with co-innovation partnerships and a new agent toolkit supporting rapid adoption. The shift from centralized AI training to distributed inference plays to Fastly’s architectural strengths.
3. Operating Leverage and Cost Discipline
Record gross and operating margins underscore Fastly’s platform efficiency and cost control. The transition to a software-defined, capital-light infrastructure enables lower incremental capital requirements versus legacy CDN peers, even as hardware component prices rise. Management’s disciplined approach to CapEx and opex is supporting both growth investments and margin expansion.
4. Go-to-Market Maturation and Global Expansion
New CMO hire and APJ investment signal a step-change in go-to-market execution. Fastly is targeting broader verticals and underpenetrated geographies, leveraging its expanded portfolio and brand repositioning to reach beyond technologists to business decision-makers. Large, multi-product deals and international wins reflect early success in this strategy.
5. Customer Commitment and Revenue Visibility
RPO and upfront commitments are rising, with 75% of RPO recognized within 12 months. The shift to larger, multi-year deals reflects customer confidence and provides improved revenue visibility, even as Fastly’s usage-based model retains some quarterly variability.
Key Considerations
This quarter marks a strategic inflection for Fastly as it transitions from a CDN-centric business to a diversified edge platform with security and compute at the forefront. Investors should weigh the following:
- Security and Compute Mix Shift: Over half of incremental 2026 revenue is expected from these higher-growth, higher-margin segments, reducing reliance on legacy CDN.
- Margin Expansion Sustainability: Record gross and operating margins are supported by structural platform efficiency, but ongoing hardware inflation and front-loaded CapEx warrant monitoring.
- AI and Edge as Growth Catalysts: Fastly’s architecture is well-aligned with distributed AI inference trends, but enterprise adoption remains in early innings.
- Pricing Discipline vs. Competitors: While some peers are raising prices, Fastly is maintaining contract discipline, leveraging platform efficiency as a potential competitive advantage.
- Revenue Concentration and Customer Mix: Top 10 customers represent 34% of revenue, but growth is increasingly broad-based and mid-market driven.
Risks
Fastly faces several risks as it executes its platform transition. The usage-based revenue model introduces quarterly variability, especially as macro and traffic patterns shift. Hardware price inflation, particularly in memory components, could pressure margins if not offset by efficiency gains. Competitive pricing actions and potential market slowdowns in e-commerce or gaming verticals may challenge network services growth. Early-stage AI adoption also brings uncertainty in timing and scale of compute revenue ramp.
Forward Outlook
For Q2 2026, Fastly guided to:
- Revenue of $170 million to $176 million (16% annual growth at the midpoint)
- Gross margin of 64% plus or minus 50 basis points
- Non-GAAP operating profit of $12 million to $16 million (8% margin at midpoint)
For full-year 2026, management raised guidance:
- Revenue of $710 million to $725 million (15% annual growth at midpoint)
- Gross margin of 64% plus or minus 50 basis points
- Operating profit of $58 million to $68 million (9% margin at midpoint)
- Free cash flow of $40 million to $50 million
Management emphasized:
- Security and compute will drive the majority of incremental growth.
- Capital spend is front-loaded but fully funded, with supply chain risks actively managed.
Takeaways
- Security and Compute Lead Growth: Platform mix shift is accelerating, with new products driving both new logos and deeper customer wallet share, setting up Fastly for durable double-digit growth.
