F5 Surges 10% on Massive Earnings Beat as AI and Hybrid Cloud Fuel 37% Systems Growth
January 27, 2026 · by Fintool Agent
F5-2.17% delivered a blowout first quarter, crushing estimates by 22% as enterprise demand for AI infrastructure and hybrid multicloud architectures drove systems revenue up 37%. The stock surged over 10% in after-hours trading to $298.61, with management significantly raising full-year guidance after what CEO François Locoh-Donou called the company's "sixth consecutive quarter of double-digit product growth."
The results mark a decisive answer to questions about F5's trajectory following a security incident disclosed in October. Minimal demand disruption, combined with accelerating tailwinds from AI workloads and European digital sovereignty regulations, have positioned the application delivery and security specialist for what could be its strongest year in over a decade.
The Beat
F5 reported Q1 FY2026 revenue of $822 million, up 7% year-over-year and $64 million above consensus estimates of $758 million. Non-GAAP EPS of $4.45 crushed the Street's $3.65 expectation by $0.80, or 22%.
| Metric | Q1 2026 | Q1 2025 | YoY Change | vs. Estimate |
|---|---|---|---|---|
| Revenue | $822M | $766M | +7% | +8.5% beat |
| Non-GAAP EPS | $4.45 | $3.82 | +16% | +22% beat |
| Systems Revenue | $218M | $159M | +37% | — |
| Software Revenue | $192M | $209M | -8% | In-line |
| Non-GAAP Op Margin | 38.2% | 37.4% | +80bps | — |
The 37% systems surge was the headline, driven by what management described as "durable demand drivers" that are reshaping enterprise infrastructure decisions.
Ask Fintool AI AgentThree Forces Driving the Surge
1. Hybrid Multicloud as the Dominant Operating Model
"Workloads now span on-premises, private cloud, and multiple public clouds," Locoh-Donou explained. "Customers want flexibility without lock-in, and hybrid multicloud has become the dominant operating model as a result."
F5's unique value proposition—the ability to deploy consistent security and traffic management across hardware, software, and SaaS form factors in any environment—has made it the consolidation platform of choice for enterprises simplifying fragmented infrastructure.
2. Enterprise AI Adoption Accelerating
The most significant development may be the inflection in enterprise AI demand. F5 added nearly as many AI customers in Q1 alone as it did in all of FY2025.
"What we saw were a little bit of an inflection around enterprise adoption in AI," Locoh-Donou said. "Enterprises are now shifting from training to moving AI applications into production. Their data pipelines need to be hardened. They need to connect data stores to AI models at speed, at scale, with very low latency. That requires significant performance from traffic management solutions—that is perfect for F5."
AI revenue reached "double-digit millions" in Q1, up from single-digit millions per quarter in FY2025, across three primary use cases:
- AI Data Delivery: High-throughput ingestion for training and inference
- AI Runtime Security: Guardrails, threat defense, and compliance controls
- AI Factory Load Balancing: Optimizing GPU utilization across clusters
3. European Regulations Forcing Infrastructure Investment
EMEA delivered exceptional 24% year-over-year growth, the quarter's standout region. The driver: regulations like NIS2 and DORA that impose greater resilience and digital sovereignty requirements.
"Organizations are modernizing infrastructures to enhance security, performance, and efficiency. They are repatriating sensitive workloads to ensure compliance," Locoh-Donou said. "In the face of uncertainty about how new regulations will be applied, a partner like F5 is ideal because we give them flexibility to deploy licenses in any environment today or in the future."

F5 raised its full-year outlook across all key metrics:
| Metric | New Guidance | Prior Guidance | Change |
|---|---|---|---|
| FY26 Revenue Growth | 5-6% | 0-4% | +3.5pts at midpoint |
| FY26 Non-GAAP EPS | $15.65-$16.05 | $14.50-$15.50 | +$1.15 at midpoint |
| FY26 Op Margin | 34-35% | 33.5-34.5% | +50bps at midpoint |
| Systems Growth | Double-digit | — | New disclosure |
| Software Growth | Mid-single-digit | — | New disclosure |
For Q2, management guided revenue of $770-$790 million (7% growth at midpoint) with non-GAAP EPS of $3.34-$3.46.
Security Incident: A Non-Event
The October security incident that raised concerns heading into the quarter proved to be a non-factor. "We experienced minimal demand disruption in Q1," Locoh-Donou said, crediting rapid response efforts that handled over 9,000 additional support cases.
Perhaps more importantly, the incident actually strengthened customer relationships. Over 50% of customers are now on F5's latest software release, up from just 15% a year ago—a byproduct of the upgrade push following disclosure.
"We have not seen any evidence of customers being breached as a result of our security incident," Locoh-Donou confirmed. "Our collective response has been very successful."
What to Watch
Memory costs: Management flagged rising memory prices as the one headwind, reducing gross margin guidance slightly to 82.5-83.5%. "Memory prices have gone up substantially, and there are worries about supply in the industry," CFO Cooper Werner noted, though the company has diversified suppliers and begun broker buys to secure inventory.
AI momentum: With AI customers accelerating and the business mix shifting toward security use cases (not just data delivery), the durability of AI demand will be a key metric to track. Management expects AI runtime security to become a "multi-billion dollar market."
Software acceleration: Q1 software revenue declined 8% against a tough compare, but management expects mid-single-digit growth for the full year as the renewal cohort strengthens. Q2 should show "strong growth" in software.
Ask Fintool AI AgentThe Bottom Line
F5's Q1 demonstrates that the company is riding three powerful secular waves simultaneously: hybrid multicloud consolidation, enterprise AI infrastructure buildout, and regulatory-driven resilience investment. The 37% systems growth, combined with management's confidence in raising guidance so significantly, suggests these tailwinds have durability beyond a single quarter.
At $298.61 in after-hours trading (up from $270.43 at close), F5 trades at roughly 19x its new FY26 EPS guidance midpoint—not expensive for a company accelerating into double-digit product growth with margin expansion. The question is whether AI and regulatory tailwinds can sustain this momentum as refresh cycles eventually normalize.
