Fortinet Earnings Call Signals AI-Fueled Growth

Fortinet ((FTNT)) has held its Q1 earnings call. Read on for the main highlights of the call.

Fortinet’s latest earnings call struck a notably upbeat tone as management highlighted robust growth in billings, revenue, and free cash flow alongside record margins. Executives acknowledged some near‑term challenges, from slower services revenue conversion to component cost pressures and questions around SASE ARR, but emphasized broad‑based demand in OT, SASE, and AI security as the dominant story.

Strong Billings Growth

Total billings jumped 31% year over year to $2.09 billion, underscoring Fortinet’s momentum across secure networking and unified SASE offerings. Management framed this performance as evidence that customers are standardizing on the platform and expanding deployments despite macro uncertainty.

Robust Revenue and Product Momentum

Revenue climbed 20% to $1.85 billion while product revenue surged 41% to $645 million, an outsized gain for a mature security vendor. The company credited a shift toward higher‑performance appliances optimized for AI workloads and data‑intensive environments as a key driver of demand.

Services and Deferred Revenue Strength

Service revenue rose a more modest 11% to $1.21 billion, but underlying metrics pointed to improving momentum with service billings accelerating 27%. Deferred revenue increased 15% and management spotlighted strong SecOps ARR growth as a leading indicator of future reported services revenue.

Outstanding Profitability and Margins

Fortinet delivered non‑GAAP gross margin of 81% and GAAP gross margin of 80.3%, reinforcing its reputation for operational efficiency. Non‑GAAP operating margin reached a first‑quarter record of 35.8%, up 160 basis points, while GAAP operating margin came in at a healthy 31.4%.

Earnings and Cash Flow Highlights

Non‑GAAP EPS increased 41% to $0.82 with GAAP EPS up 29% to $0.72, reflecting the combination of growth and disciplined cost control. Free cash flow hit a record $1.01 billion, or $1.07 billion on an adjusted basis, translating to a hefty 58% free cash flow margin.

Capital Return and Buybacks

The company continued to return capital to shareholders, repurchasing 10.6 million shares for $827 million during the quarter. Additional buybacks of 1.9 million shares quarter‑to‑date brought total repurchases higher, with roughly $766 million still authorized for future share repurchases.

AI-Driven and Segment-Specific Wins

Operational technology billings grew more than 70%, unified SASE billings advanced 31%, and AI‑driven security operations billings increased 23%. Large enterprise deals over $1 million and total deal value both climbed more than 60%, underscoring Fortinet’s growing presence in big‑ticket, mission‑critical deployments.

Customer Additions and Product Launches

Fortinet added over 6,600 new organizations to its FortiOS platform, signaling continued customer acquisition in a crowded market. The firm also launched new 3500G and 400G series hardware aimed at boosting performance for AI and high‑throughput use cases, aligning the portfolio with emerging infrastructure trends.

Services Revenue Conversion Lag

Despite strong product sales and faster service billings, services revenue growth remained at 11%, creating a perception of lag. Management explained that the conversion from billings and deferred revenue to recognized service revenue takes time and indicated they expect a pickup in the back half of the year.

Component Cost Pressure and Pricing Impact

Executives acknowledged ongoing component and memory cost pressures, which have required careful pricing and margin management. Recent pricing changes created a low single‑digit drag on product revenue growth, and guidance now embeds both these pricing actions and planned infrastructure investments of $350 million to $550 million this year.

Supply-Chain and Pull-Forward Uncertainty

The company cautioned that supply‑chain normalization and customer ordering patterns remain hard to time precisely. While management believes there was limited order pull‑forward this quarter, they conceded that the duration of current dynamics and channel inventory levels still carry some uncertainty.

SASE ARR and ARR Deceleration Questions

Analysts pressed for clarity on a perceived deceleration in SASE ARR, seeking alignment with reported billings strength. Fortinet pointed to 31% growth in unified SASE billings and noted that FortiSASE is now adopted by about 18% of large enterprise customers, though some ambiguity around near‑term ARR cadence remains.

Reliance on AI-Driven Tailwind

Management highlighted AI infrastructure buildouts as a major catalyst for recent wins, particularly in high‑performance firewall and secure networking projects. While this AI wave is driving current demand, it introduces some concentration risk if AI spending patterns or deployment timelines shift materially.

Raised and Reiterated Guidance

Fortinet raised and reaffirmed its 2026 outlook, signaling confidence in sustained growth and profitability. The company now targets billings of $8.8 billion to $9.1 billion and revenue of $7.71 billion to $7.87 billion, alongside double‑digit service revenue growth and non‑GAAP operating margins in the mid‑30s.

Forward guidance for the near term was also upbeat, with Q2 billings expected between $2.09 billion and $2.19 billion and revenue between $1.83 billion and $1.93 billion. Management forecast non‑GAAP gross margin of roughly 79.5% to 80.5%, operating margin of 33% to 35%, and EPS of $0.72 to $0.76 while planning significant infrastructure investments and maintaining an 18% non‑GAAP tax rate.

Overall, Fortinet’s earnings call painted a picture of a security vendor firing on multiple cylinders as it rides demand for secure networking, SASE, and AI‑driven security. Investors will watch how quickly services revenue catches up, how SASE ARR trends evolve, and whether AI‑linked demand proves durable, but for now the company’s raised outlook and strong execution appear to justify the optimism.
