Accuray (ARAY) Q4 2025: Service Margins Climb 900bps as International Mix Hits 80%
Service margin expansion and international growth defined Accuray’s fourth quarter, as the company navigated severe tariff volatility and geopolitical shocks but still delivered margin gains and record service revenue. Leadership’s focus on operational agility and cost controls is reshaping the business model, with a strategic pivot toward emerging markets and recurring service streams. FY26 guidance embeds cautious assumptions on China and tariff risk, but backlog strength and new product launches set the stage for further EBITDA leverage.
Summary
- Service Margin Breakout: Nine-point improvement in service margin underscores progress on cost and pricing levers.
- International Revenue Dominance: Overseas markets now drive 80% of total revenue, shifting Accuray’s risk and opportunity profile.
- FY26 Inflection Setup: Margin expansion, backlog conversion, and new launches position Accuray for operating leverage despite macro caution.
Performance Analysis
Accuray’s Q4 2025 results reflected a business in transition, with total revenue of $128 million, down 5% YoY, as tariff swings and regional instability forced rapid operational pivots. Product sales fell 11% due to China and EIMEA (Europe, India, Middle East, Africa) disruptions, but service revenue delivered $56.9 million, up 4%, marking the highest annual growth in years and now providing a more predictable, high-margin base.
Gross margin for the quarter rose to 30.6%, up 200bps YoY, despite product margin compression from deferred high-margin China shipments, which will reverse in FY26. Service gross margin surged nine points, powered by reduced parts consumption and pricing actions. The Americas returned to growth with a 24% revenue increase, while APAC surged 22%, offsetting declines in Japan and EIMEA. Backlog ended at $427 million, representing over 18 months of product revenue visibility.
- Service Revenue Resilience: Recurring service contracts now comprise 90% of service revenue, supporting stable cash flow and margin expansion.
- Backlog Quality and Conversion: Proactive backlog management and a 1.2 book-to-bill ratio signal ongoing demand and conversion discipline.
- Cost Controls and Operating Leverage: Operating expenses fell 2% YoY for the full year, with a focus on R&D ROI and process efficiency.
Adjusted EBITDA for FY25 climbed 44% to $28.3 million, with deferred China margin set to boost future quarters. Debt refinancing and liquidity actions underpin confidence in margin and cash flow improvement for FY26.
Executive Commentary

Strategic Positioning
1. International Mix and Emerging Market Penetration
International markets now represent 80% of Accuray’s revenue, with APAC and China leading growth. Helix, value segment linear accelerator, and Tomosi, China-specific platform, are driving traction in high-growth regions, while the Americas and Japan remain challenged by aged installed bases and slower capital cycles. Leadership is targeting emerging markets for both product and service expansion, leveraging local regulatory wins and product fit.
2. Service Business as Margin Engine
Service revenue is the cornerstone of Accuray’s margin expansion strategy, with recurring contracts and value-added offerings like CyberCom, remote system analytics, boosting both top-line and profitability. Margin gains stem from R&D-driven reliability, reduced parts usage, and strategic pricing. The company’s Accurate Care Service Initiative aims to further optimize uptime and cost-to-serve, feeding a virtuous cycle of installed base growth and service capture.
3. Tariff Mitigation and Supply Chain Flexibility
Tariff volatility forced Accuray to rapidly implement mitigation levers: duty drawback programs, dual sourcing, and the planned foreign trade zone (FTZ) at the Madison facility. FTZ, a customs designation allowing deferred or reduced duties, is expected to shield margins from future tariff shocks by the second half of FY26. These moves, combined with logistics agility, have already halved the effective tariff impact in Q4.
4. Capital Structure Reset and Liquidity Enhancement
Debt refinancing extended maturities by five years and consolidated obligations under a single lender, unlocking $190 million in new financing and providing balance sheet flexibility. This capital structure shift enables greater investment in innovation, margin initiatives, and market expansion without near-term refinancing risk.
5. Product Innovation and Installed Base Leverage
New launches—such as the CyberKnife S7 Momentum, robotic radiosurgery system, and adaptive radiotherapy solutions—target premium developed markets, aiming to catalyze replacement demand among aging systems in the US and Europe. FY26 will see a substantial installed base ramp, feeding future service revenue and supporting the company’s recurring revenue flywheel.
Key Considerations
Accuray’s Q4 underscores a business model shift toward recurring service and international growth, but execution risk remains as macro and geopolitical factors continue to buffet regional demand and supply chains.
Key Considerations:
- Service Margin as Core Profit Driver: Sustained margin expansion depends on continued execution of parts reduction and premium support initiatives.
- Backlog Visibility vs. Conversion Risk: $427 million backlog offers revenue visibility, but regional instability and capital cycle delays could impede timely conversion.
- Tariff Policy Uncertainty: Temporary tariff relief in China is only extended for 90 days, and future escalations could impact both cost structure and shipment timing.
- US Market Recovery Pace: Domestic order growth remains muted, with upside tied to new product launches and aging installed base replacement.
- Capital Allocation Discipline: Recent refinancing provides liquidity, but disciplined investment in R&D and go-to-market will be key to sustaining EBITDA leverage.
Risks
Accuray faces material exposure to tariff policy shifts, especially in China, where only temporary relief has been secured and customer funding delays persist. Geopolitical instability in EIMEA and macro softness in developed markets could delay backlog conversion and pressure near-term product revenue. Execution on supply chain localization and FTZ implementation will be critical, as will delivering on service margin improvement amid rising cost pressures.
Forward Outlook
For Q1 FY26, Accuray expects:
- Revenue weighted toward the second half of the year (45% H1, 55% H2)
- EBITDA contribution skewed to H2 (30% H1, 70% H2)
For full-year FY26, management guided:
- Revenue: $471 million to $485 million
- Adjusted EBITDA: $31 million to $35 million
Guidance assumes:
- Continued tariff mitigation and FTZ implementation in H2
- Gradual improvement in China and US order trends, with caution on macro and funding dynamics
Takeaways
Accuray’s margin expansion and international growth are reshaping its earnings profile, but volatility in tariffs and regional demand require operational agility and ongoing cost discipline.
- Service Margin Leverage: Service business is now the primary engine for margin expansion, with recurring contracts and operational efficiency at the forefront.
- International Focus: 80% of revenue from overseas markets reflects a strategic shift, but also heightens exposure to geopolitical and policy swings.
- Execution Watchpoints: Investors should monitor tariff developments, FTZ progress, US order recovery, and the realization of deferred China margin as key drivers for FY26 performance.
Conclusion
Accuray’s Q4 2025 results highlight a strategic transition toward recurring service revenue, international market leadership, and margin expansion. While macro and policy headwinds persist, the company’s operational discipline and new capital structure provide a foundation for further EBITDA growth and improved cash flow in FY26.
Industry Read-Through
Accuray’s experience this quarter is a bellwether for medtech peers with global supply chains and emerging market exposure. The rapid operational pivots to manage tariffs, supply chain localization, and regional instability will be instructive for other capital equipment providers facing similar volatility. Service margin expansion and recurring revenue models are gaining favor in the sector, as product sales become more exposed to macro cycles and trade policy risk. Expect further industry emphasis on cost-to-serve, pricing discipline, and installed base monetization, with a growing premium on operational flexibility and capital allocation agility.
