Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 21% year-over-year to $276.7 million, driven by new customer acquisitions and expansion within the existing base.
- Profitability Improvement: GAAP Net Loss improved significantly to $76.2 million from $208.2 million in the prior year. This improvement was primarily due to the non-recurrence of a $136.0 million discrete tax expense related to an Israeli Tax Authority (ITA) matter recorded in Q1 2025.
- Non-GAAP Performance: The company achieved Non-GAAP operating income of $10.5 million, compared to a loss of $3.9 million in the prior year, reflecting improved operational efficiency.
- Cost Structure: Cost of revenue increased 38% due to higher cloud hosting usage and customer support costs. Research and Development expenses rose 33% due to increased headcount and stock-based compensation related to acquisitions.
- Acquisitions: The company completed acquisitions of Observo and Prompt in fiscal 2026, contributing to intangible asset amortization and stock-based compensation expenses.
Guidance, Outlook, and Risks
- Restructuring: In May 2026, the company announced a new restructuring plan involving an 8% workforce reduction. A one-time charge of approximately $25.0 million is expected in Q2 fiscal 2027.
- Tax Liability: The company entered into an agreement with the ITA in January 2026 resolving transfer pricing matters. A total tax expense of $180.0 million (plus interest) was recorded in fiscal 2026. Remaining liability is $164.1 million, payable through fiscal 2031. In a change of control, the full unpaid amount plus interest ($267.1 million) would accelerate.
- Strategic Investments: The company made a $100.0 million strategic investment in Knight JV, LLC during the quarter.
- Risks: Key risks include the impact of global macroeconomic conditions on IT spending, intense competition in the cybersecurity market, reliance on third-party cloud infrastructure (AWS), and potential disruptions from geopolitical conflicts (specifically noting operations in Israel).
