Fastly Inc - Class A (NASDAQ:FSLY) delivered a decisive fourth-quarter earnings beat, sending its shares sharply higher in after-hours trading. The edge cloud platform’s results exceeded analyst expectations across key financial metrics, and its forward guidance suggests the momentum is expected to continue into the new fiscal year.
Earnings and Revenue: A Clear Beat
The company’s performance for the quarter ended December 31, 2025, showcased accelerating growth and improving profitability. Fastly reported revenue of $172.6 million, a 22.8% increase year-over-year. This figure comfortably surpassed the analyst consensus estimate of approximately $164.6 million.
More notably, the company’s profitability on an adjusted basis came in significantly stronger than anticipated. Fastly reported non-GAAP earnings per share (EPS) of $0.12, more than double the $0.057 analysts had forecast. This performance marks a substantial improvement from the non-GAAP net loss of $0.02 per share reported in the same quarter last year.
Key financial highlights from the quarter include:
- Revenue Growth: $172.6M actual vs. $164.6M estimated.
- Non-GAAP EPS: $0.12 actual vs. $0.057 estimated.
- Gross Margin Expansion: GAAP gross margin improved to 61.4%, up from 53.4% a year ago.
- Positive Cash Flow: Generated $22.4 million in operating cash flow and $8.6 million in free cash flow.
Market Reaction and Forward Guidance
The market’s reaction to the report was immediately positive. Following the earnings release, Fastly’s stock jumped approximately 13.6% in after-hours trading. This surge reflects investor approval of both the strong quarterly outperformance and, critically, the company’s optimistic outlook for 2026.
Management provided guidance that exceeded existing analyst expectations, reinforcing the positive narrative. For the first quarter of 2026, Fastly anticipates revenue between $168 million and $174 million, with a midpoint of $171 million. This outlook is nearly 7% above the analyst sales estimate of $162.8 million for Q1.
The full-year 2026 guidance was even more impactful. The company projects revenue in the range of $700 million to $720 million. The midpoint of this guidance, $710 million, stands well above the analyst consensus estimate of approximately $681.2 million for the full year.
Strategic and Operational Highlights
Beyond the headline numbers, Fastly’s press release highlighted several areas of strategic progress that underpin its improved financial trajectory:
- Diversified Growth: Security revenue grew 32% year-over-year, and "Other" revenue—which includes Compute and Observability solutions—surged 78%, indicating successful expansion beyond its core content delivery network services.
- Strong Customer Metrics: The enterprise customer count increased to 628, up 32 from the prior year. The Last Twelve Months (LTM) Net Retention Rate improved to 110%, suggesting existing customers are spending more.
- Balance Sheet Management: The company raised $180 million through a convertible notes offering and used a portion to repurchase notes due in 2026, improving its liquidity position.
- Product Innovation: Recent launches include an API Security enhancement (API Inventory), a beta AI Assistant for developers, and performance upgrades to its Compute@Edge platform.
Conclusion
Fastly’s fourth-quarter report represents what CEO Kip Compton termed an "inflection" in the company’s growth. By significantly beating revenue and profit estimates and then issuing guidance that outpaces analyst models, Fastly has demonstrated tangible progress in its turnaround and growth strategy. The market’s double-digit percentage gain after hours is a direct validation of these results. The key question for investors now will be the company’s ability to execute against its elevated full-year targets and continue capitalizing on tailwinds in edge computing and security.
