Fortinet beat guidance across billings, revenue, margins and EPS — billings rose 31%, revenue 20%, product revenue 41%, with a record $1 billion free cash flow and non‑GAAP operating margin near 36%.
Demand is being driven by AI-related deployments, networking‑security convergence, and OT security (OT billings >70%); Secure Networking billings grew 32% and Unified SASE 31%, and the company introduced higher‑performance FortiGate appliances for AI data centers.
Management raised Q2 and full‑year guidance, continued capital returns (repurchased 10.6M shares for $827M plus 1.9M/$146M YTD with ~$766M left) and signaled low‑single‑digit product pricing adjustments tied to component costs.
Cybersecurity Demand Is High—Yet This ETF Is on Sale
Fortinet (NASDAQ:FTNT) reported first-quarter 2026 results that management said exceeded guidance across billings, revenue, margins, and earnings per share, citing broad-based demand and what executives described as accelerating tailwinds tied to artificial intelligence, networking-and-security convergence, and operational technology (OT) security.
Quarter highlights: billings up 31% and record free cash flow
Founder, Chairman, and CEO Ken Xie said Fortinet delivered “excellent first quarter result, exceeding our guidance through strong execution and broader-based demand.” He reported billings growth of 31%, total revenue growth of 20%, and product revenue growth of 41%. Xie also highlighted profitability and cash generation, noting non-GAAP and GAAP operating margins of 36% and 31%, respectively, and “a record $1 billion free cash flow.” He added that GAAP earnings per share increased 29%.
CFO Christiane Ohlgart said Fortinet “exceed[ed] the high end of our guidance across billings, total revenue, operating margin, and earnings per share.” She reported total billings of $2.09 billion, up 31%, and revenue of $1.85 billion, up 20%.
On the revenue mix, Ohlgart said product revenue increased 41% to $645 million as customers shifted toward higher-performance products, including “a number of AI-related deployments where customers invested in FortiGates to support increased throughput, segmentation, and security requirements across AI infrastructure.” Service revenue grew 11% to $1.21 billion, while service billings growth “re-accelerated to 27%” and deferred revenue increased 15%.
Margins also came in above expectations, according to Ohlgart. Non-GAAP gross margin was 81% and GAAP gross margin was 80.3%. Non-GAAP operating margin was 35.8%, a first-quarter record, while GAAP operating margin was 31.4%.
Fortinet posted non-GAAP EPS of $0.82, up 41%, and GAAP EPS of $0.72, up 29%, Ohlgart said. Free cash flow was $1.01 billion, with adjusted free cash flow of $1.07 billion, up 27%, representing a 58% margin.
Demand drivers: AI, platform consolidation, and OT security
Xie said Fortinet’s “convergence of networking and security” approach is “accelerating in the AI era,” as customers adopt the company’s platform across secure networking, unified SASE, and security operations on a single FortiOS operating system. He pointed to FortiOS 8.0, Fortinet’s proprietary FortiASIC technology, and direct supply chain management as differentiators supporting market share gains.
Ohlgart described demand as broad-based across “customer types, industry verticals, our geos, and all three pillars,” with particular strength in large enterprise. She said the number of deals greater than $1 million and total deal value both grew over 60%, and Fortinet saw strong growth in both Europe and the U.S.
In OT, Xie said “OT security accelerated in the quarter with OT billing growth over 70%,” and Ohlgart said Secure Networking billings grew 32% driven by FortiGate demand as customers expanded protection across OT environments. Xie argued OT security helps protect critical “bottom layers” of infrastructure supporting AI.
In security operations, Xie said AI-driven security operations billings grew 23%, supported by “more than 20 AI-enabled solutions,” as customers consolidate vendors and simplify operations. Ohlgart added that customers deploying AI are concerned about “traffic flows and shadow AI,” driving interest in visibility and monitoring capabilities.
Secure Networking and Unified SASE: growth and new bundling strategy
Fortinet reported Secure Networking billings growth of 32% and Unified SASE billings growth of 31%. Xie said Fortinet’s SASE firewall “significantly reduce[s] complexity” by delivering core capabilities natively integrated in one operating system. He also emphasized Fortinet’s global cloud infrastructure and its ability to support “sovereign and private SASE” deployments to meet data sovereignty and regulatory requirements.
During Q&A, Xie said Unified SASE comprises SD-WAN and secure service edge offerings including FortiSASE, and he said Unified SASE is “about 25% of billing right now.” He also discussed sovereign SASE, saying it is “almost the same size as the cloud-based SASE, probably even bigger,” and noted service providers—particularly in Europe—are launching sovereign SASE services using Fortinet products.
Management also discussed efforts to increase adoption through packaging. Ohlgart said Fortinet is “introducing a new SD-WAN and SASE services bundle designed to broaden adoption and further support services revenue over time.” In response to analyst questions, Xie said the bundle is intended to accelerate customers turning on SD-WAN and SASE/Zero Trust capabilities from existing firewall deployments, and COO John Whittle did not speak during the transcript provided.
AI data center opportunity and product positioning
Executives repeatedly tied product momentum to AI infrastructure buildouts. Xie said AI-generated traffic increases throughput and “east-west traffic,” driving demand for internal segmentation and higher-performance security. He argued Fortinet’s ASIC-based approach provides performance and energy-cost advantages in data center environments, saying Fortinet is “the only cybersecurity company build their own ASIC chip from day one.”
Fortinet also announced new high-end appliances during the call. Xie said the company introduced the FortiGate 3500G and 400G, which he said deliver “significant performance improvement over previous generations.”
Ohlgart highlighted several large deals discussed as examples of demand:
A cloud infrastructure provider focused on GPU compute for AI workloads selected Fortinet to secure a new AI data center using FortiGates for perimeter protection, segmentation, and connectivity.
A generative AI company in the Middle East selected Fortinet for the initial phase of an AI data center project.
A multinational energy company selected Fortinet to deploy SD-Branch solutions across more than 3,000 locations and OT security for an additional 300 sites, and is exploring an expansion into FortiSASE.
A global manufacturer selected FortiSASE to secure approximately 40,000 users as part of a remote access modernization initiative.
Capital return, pricing posture, and raised guidance
Fortinet continued to return capital. Ohlgart said the company repurchased 10.6 million shares for $827 million in the first quarter and an additional 1.9 million shares for $146 million quarter-to-date, leaving roughly $766 million remaining under authorization.
On pricing, Ohlgart said guidance includes a “low-single digit amount specifically into product” from pricing. She said Fortinet is “contemplating pricing actions” as component costs increase, with a stated intention to lower prices when cost pressures ease. Xie emphasized the company’s policy is to maintain healthy margins rather than use supply conditions to expand margins, describing “monthly adjustment” tied to costs.
Given first-quarter execution, management raised full-year guidance. For the second quarter, Ohlgart guided to billings of $2.09 billion to $2.19 billion and revenue of $1.83 billion to $1.93 billion, with non-GAAP operating margin of 33% to 35% and non-GAAP EPS of $0.72 to $0.76.
For full-year 2026, Fortinet expects billings of $8.8 billion to $9.1 billion and revenue of $7.71 billion to $7.87 billion. Service revenue is expected to be $5.09 billion to $5.15 billion, with Ohlgart saying the company continues to expect services revenue growth to “pick up in the second half of the year,” citing accelerating product revenue and service billings as leading indicators.

Four leading AI models discuss this article
"Fortinet’s proprietary ASIC strategy provides a unique performance-to-cost advantage in AI data centers that software-only competitors currently cannot replicate."
Fortinet’s Q1 results are undeniably impressive, with 31% billings growth and record 36% operating margins suggesting the company is effectively capturing the AI infrastructure spend. The shift toward high-performance FortiGate appliances for AI data centers validates their proprietary ASIC strategy, providing a tangible moat against software-defined competitors. However, the reliance on 'low-single-digit' pricing adjustments to manage component costs is a potential red flag; if inflation persists or supply chain volatility spikes, these adjustments could alienate price-sensitive enterprise customers. While the $1 billion free cash flow is a massive cushion, the stock is currently priced for perfection, and any deceleration in the 're-accelerating' service revenue will be punished severely by the market.
Fortinet’s reliance on hardware-centric security may become a liability if the industry shifts rapidly toward pure-play cloud-native SASE, leaving their ASIC-heavy infrastructure as an expensive, legacy-prone anchor.
"FTNT's ASIC-powered convergence play uniquely positions it for AI infrastructure security, evidenced by 41% product growth and >60% rise in $1M+ deals."
Fortinet (FTNT) delivered a blowout Q1: billings +31% to $2.09B, revenue +20% to $1.85B, product revenue +41% to $645M on AI data center wins and OT billings >70%. Record $1.01B FCF (58% margin) and 35.8% non-GAAP op margin highlight operational leverage. Secure Networking (+32%) and Unified SASE (+31%, ~25% of billings) billings signal platform stickiness via FortiOS/ASIC edge. Raised FY2026 billings guide $8.8-9.1B implies 16-22% growth; new FortiGate 3500G/400G targets AI throughput/segmentation. $827M buybacks YTD reinforce shareholder value amid broad demand.
Services revenue grew just 11% despite 27% billings re-acceleration, risking future deceleration if product pull-forward exhausts; low-single-digit pricing hikes tied to components expose margin vulnerability if supply chains don't normalize or competition (e.g., PANW, ZS) erodes pricing power.
"FTNT's OT security >70% growth and platform consolidation story (Secure Networking +32%, SASE +31%) are more durable than the AI hype, but service revenue stalling at 11% growth is the real risk to watch."
FTNT's beat is real—31% billings growth, 36% non-GAAP op margin, $1B FCF, and raised guidance are hard to dismiss. The AI tailwind narrative is credible: FortiGate demand for data center segmentation and throughput is a legitimate use case, not vaporware. OT security >70% growth is the sleeper here—less crowded than AI, more defensible. But the article buries a critical detail: product revenue is 35% of total revenue, growing 41%, yet service revenue (65% of total) is only growing 11%. Management is banking on 're-acceleration' in H2, but that's a promise, not a fact. Margin expansion from 36% to guidance range of 33-35% next quarter signals either conservatism or real headwinds. The $766M buyback authorization left is also modest relative to market cap—not a sign of confidence.
If AI infrastructure capex moderates in H2 (a real risk given GPU oversupply concerns), FortiGate throughput demand could flatten fast, and the 41% product revenue growth becomes a one-quarter anomaly rather than a trend. Service revenue deceleration to 11% is the canary—if that doesn't re-accelerate as promised, the whole growth narrative cracks.
"Fortinet's upside hinges on durable AI-driven data-center demand and disciplined pricing; without those, the Q1 strength may not translate into sustained outperformance."
Fortinet delivered a solid Q1 beat with 31% billings growth, 20% revenue rise, 41% product growth, and $1.01B free cash flow, underscoring AI-related deployments and OT/security strength. The margin expansion on non-GAAP metrics and raised guidance support a constructive read, while new FortiGate appliances and bundling for SD-WAN/SASE align with a data-center/security convergence narrative. However, the rally hinges on durable AI capex and the sustainability of pricing discipline; if AI budgets soften or pricing pressure intensifies, margin leads and the multiple could compress despite the headline strength.
The strongest counter: AI-driven demand may prove cyclical or peak, and aggressive pricing/bundling could erode margins faster than anticipated if competitors flood the market with lower-cost options or if AI spend slows.
"The widening gap between product and service growth suggests the current AI-driven hardware cycle may produce a lower-margin, less-sticky recurring revenue stream than previous product cycles."
Claude is right to fixate on the 11% service revenue growth, but everyone is missing the second-order effect: Fortinet’s massive product-to-service conversion lag. If product revenue is growing at 41% but services are stuck at 11%, the 're-acceleration' isn't just a promise—it's a mathematical necessity as the installed base matures. However, if this cycle is purely driven by one-off AI data center hardware refreshes, the recurring service tail will be thinner than historical cycles, permanently compressing long-term margins.
"AI-driven product growth features delayed and potentially weaker service conversion, risking permanent margin compression."
Gemini, your 'mathematical necessity' for service re-acceleration overlooks deal structure: AI data center FortiGate wins are often hardware-heavy pilots with deferred service ramps (12-18 months historically). If these are capex spikes not sticky subscriptions, the service tail thins permanently, compressing margins below 35% long-term despite today's FCF bonanza. Nobody's quantified the AI revenue concentration risk—likely 20-30% of product growth.
"The service lag thesis needs empirical validation—deal structure data, not just historical patterns, will determine if this is cyclical or structural."
Grok and Gemini are both assuming 12-18 month service lag is inevitable, but they haven't challenged the premise: are these AI data center deals actually structured as hardware pilots, or are they full platform deployments with immediate service attach? FTNT's unified SASE bundling (31% billings growth) suggests sticky platform lock-in, not transactional hardware sales. If service re-acceleration fails to materialize by Q3, *then* we know it's a pilot cycle. Until then, the 11% growth could reflect mix shift, not demand weakness.
"Service attach rates and deal structure will determine Fortinet's service revenue trajectory, not a universal 12–18 month lag."
To Grok: I wouldn’t assume a fixed 12–18 month service ramp. If Fortinet closes multi-year Unified SASE deals with immediate service attach (SOC, threat intel feeds, managed services), service revenue could re-accelerate sooner, not later, and margins may hold if these attach rates stay high. The big risk is deal structure and attachment, not a universal lag. If attach is low, your thesis holds.
Panelists agree that Fortinet's Q1 results were impressive, with strong billings growth and record margins. However, there's disagreement on the sustainability of service revenue growth, with some seeing a mathematical necessity for re-acceleration and others questioning the deal structure and potential for permanent margin compression.
