Fastly Shares Soar 62%: 5 Hidden Facts Investors Must Know About the Edge-Cloud Leader
The dramatic rise of Fastly shares soaring 62% has captured attention across the United States, United Kingdom, China, and other global markets. With an InvestingPro undervalued rating, this edge-cloud company is not only a headline-grabbing stock but also a case study in revenue growth, strategic innovation, and market positioning. This article dives into the lesser-known factors behind the stock surge and why Fastly could be an overlooked investment opportunity.
1. The Real Numbers Behind the Stock Rally
The “62% surge” in Fastly shares is backed by solid financial performance. In Q3 2025, Fastly (NYSE: FSLY) reported total revenue of $158.2 million, reflecting a 15% year-over-year increase.[1]
- Network services revenue grew 11% to $118.8M.
- Security revenue surged 30% to $34.0M.
- Compute & Observability revenue increased 51% to $5.4M.
- Operating cash flow was $28.9M and free cash flow $18.1M.
- Non-GAAP EPS rose to $0.07 while GAAP net loss narrowed to $29.5M.
These metrics indicate that the stock rally is underpinned by genuine business growth rather than speculation.
2. Understanding the InvestingPro Undervalued Rating
The InvestingPro undervalued rating highlights a significant gap between Fastly's intrinsic value and current market price. Despite steady revenue growth of 6.26% and strong gross margins (~54%), Fastly trades at an EV/Sales multiple of only 1.8×, far below the sector average of 6.9×.[2]
Investors interpreting the fair value gap as potential upside could consider Fastly a compelling target, especially as it continues to strengthen its edge-cloud platform offerings.
3. Expanding Beyond Traditional CDN
Fastly is shifting from a simple CDN provider to a comprehensive edge cloud platform with high-growth areas in security and compute:
- Security solutions grew 30% YoY, reflecting enterprise demand for secure edge services.
- Compute & Observability grew 51% YoY, indicating promising new revenue streams.
- Management is investing heavily in platform enhancements to drive future growth.
This strategic pivot positions Fastly as a modern edge-cloud leader, differentiating it from legacy CDN competitors and appealing to global investors.
4. Diversified Customer Base Reduces Risk
Fastly is actively reducing reliance on top clients, enhancing long-term stability:
- Revenue from the top 10 customers fell to 33% of total revenue, down from 38%.
- Revenue from customers outside the top 10 increased 17% YoY.
- Enterprise customer count grew to 627 in Q3 2025.
Lower concentration risk contributes to predictable revenue growth and strengthens the investment thesis, particularly in volatile markets.
5. Global Perspective: Opportunities for US, UK, and China Investors
United States
Strong security and compute revenue aligns with rising demand for low-latency content delivery and regulatory compliance. Fastly's valuation gap also makes it attractive to growth-value hybrid investors.
United Kingdom
European enterprises are increasingly adopting edge architectures. Fastly’s diversified revenue and global footprint appeal to investors seeking stability amid currency fluctuations and macroeconomic changes.
China & Asia-Pacific
With booming demand for gaming, streaming, and e-commerce, Fastly's edge-compute and security offerings have significant growth potential. Despite regulatory barriers, structural trends favor edge-infrastructure adoption.
6. Risks to Consider
Investors should remain aware of potential risks:
- GAAP losses continue despite improving cash flow.
- Growth depends on security and compute segment adoption amid competitive pressures.
- Market skepticism exists, reflected in lower trading multiples compared to larger peers.
Conclusion
The surge in Fastly shares soaring 62% reflects a combination of strong revenue growth, evolving product mix, and a substantial intrinsic value/fair value gap highlighted by an InvestingPro undervalued rating. While risks remain, the company’s expansion into security and edge compute, combined with reduced customer concentration and improved cash flow, positions Fastly as a compelling edge-cloud leader for investors across the United States, United Kingdom, and China.
