OSI Systems (OSIS) Q4 2026: Record Backlog of $1.9B Offsets Middle East Delivery Delays
OSI Systems closed fiscal 2026 with record earnings per share and operating cash flow despite a 4% revenue decline in Q4 driven by geopolitical disruptions. The company’s substantial backlog and recent contract wins provide strong visibility into fiscal 2027 and beyond, supported by robust demand across Security and Optoelectronics segments. Fiscal 2027 guidance anticipates mid-single-digit revenue growth and double-digit EPS expansion, reflecting disciplined execution amid ongoing regional uncertainties.
Summary
- Backlog Strength: Record $1.9 billion backlog underpins revenue visibility despite near-term delivery deferrals.
- Segment Momentum: Security faces timing headwinds, while Optoelectronics and Healthcare show solid growth and margin expansion.
- Strategic Capital Allocation: Aggressive share repurchases and liquidity enhancements position OSI for sustained investment and shareholder returns.
Business Overview
OSI Systems designs and manufactures specialized electronic systems and components, operating through three segments: Security, which offers advanced inspection and screening solutions; Optoelectronics and Manufacturing, supplying high-performance optoelectronic products and precision manufacturing services; and Healthcare, focused on patient monitoring and diagnostic cardiology. Revenue is generated through product sales and recurring service contracts across over 170 countries.
Performance Analysis
Fiscal 2026 revenues reached a record $1.79 billion, up 4% year-over-year, driven by broad-based growth in Optoelectronics and Healthcare segments. However, Q4 revenues declined 4% to $484 million, primarily due to delivery timing shifts in the Security division related to conflicts in the Middle East. These deferrals, totaling approximately $50 million, were not cancellations but postponed deliveries, remaining firmly in the backlog.
Despite revenue pressures, OSI delivered record non-GAAP earnings per share of $3.78 in Q4, a 17% increase year-over-year, supported by operating margin expansion to 17.7%, up 200 basis points. Operating cash flow was exceptional, with $182 million generated in Q4 and $276 million for the full year, reflecting strong collections including $159 million from the largest Mexican customer. The company also reduced net leverage to approximately 2.1x, strengthened cash reserves to $360 million, and repurchased 565,000 shares in Q4.
- Revenue Mix Impact: Optoelectronics and Healthcare grew revenues by 5% in Q4, offsetting a 7% decline in Security impacted by geopolitical delays.
- Margin Expansion Drivers: Improved product mix and operational efficiencies drove gross margin to 34.7% and operating margin gains across all divisions.
- Backlog and Bookings: Book-to-bill ratio remained above one for the year, culminating in a record backlog of $1.9 billion, providing strong future revenue visibility.
In summary, OSI’s financial performance reflects resilience amid regional challenges, with strong underlying demand and disciplined cost management supporting profitability and cash generation.
Executive Commentary
"Fiscal 2026 was a strong year for OSI Systems, capped by record annual revenues of $1.79 billion, record Q4 and annual non-GAAP earnings per share, and record operating cash flow. While the Security Division faced revenue headwinds from the Middle East conflicts, Opto Electronics delivered strong growth and Healthcare posted an improved quarter. Our record backlog of approximately $1.9 billion gives us good visibility as we enter fiscal 2027."
Ajay Mehra, President & CEO
"We closed the year with exceptional cash generation and strong profitability driven by solid adjusted operating margin expansion. Our board recently authorized an additional 1 million shares for repurchase, reflecting confidence in our long-term strategy and cash flow generation. We expect fiscal 27 to deliver 5% to 8.1% revenue growth and 7.5% to 11% non-GAAP EPS growth."

Strategic Positioning
1. Security Division Navigates Geopolitical Headwinds
The Security segment experienced delivery timing delays due to conflicts in the Middle East, impacting Q4 revenues by approximately $50 million. However, these orders remain in backlog and are expected to be fulfilled in fiscal 2027 and beyond. Recent contract awards include two five-year IDIQ contracts with the U.S. Customs and Border Protection (CBP) totaling a ceiling of $285 million, with initial delivery orders already booked. The division is also expanding recurring service revenues supported by a growing installed base, enhancing revenue stability and margin profile.
2. Optoelectronics and Manufacturing Drives Broad-Based Growth
Optoelectronics posted 9% full-year revenue growth to $451 million, fueled by diversified demand across aerospace, defense, healthcare, and industrial markets. The segment benefits from a vertically integrated manufacturing model and global footprint, enabling supply chain resilience and customer diversification. Operating margins expanded to 14.7% in Q4, with management signaling further margin improvement through revenue growth and favorable product mix.
3. Healthcare Division Shows Margin Turnaround
Healthcare revenues grew approximately 5% in Q4, with adjusted operating margin improving dramatically to 10% from 1% in the prior year quarter. This reflects operational improvements and increased scale. The division is focused on expanding its installed base and advancing next-generation patient monitoring platforms, positioning for sustained growth and profitability improvement.
4. Capital Allocation Emphasizes Shareholder Returns and Financial Flexibility
OSI repurchased 1.1 million shares during fiscal 2026 and has an additional 1 million shares authorized for buyback with no expiration. The company refinanced and extended its credit facility, increasing gross debt but improving liquidity and flexibility. Cash on hand rose to $360 million, supporting both strategic investments and shareholder returns.
5. Innovation and R&D Investment Support Long-Term Growth
Research and development expenses increased modestly to $19.5 million in Q4, reflecting ongoing commitment to innovation. Management expects continued elevated R&D spending to advance new product initiatives, including security technology enhancements and healthcare solutions, underpinning competitive positioning and future revenue streams.
Key Considerations
Fiscal 2026 demonstrated OSI Systems’ ability to maintain profitability and cash flow despite external disruptions, with a robust backlog and pipeline supporting confidence in future growth. Key considerations for investors include:
- Geopolitical Risk Impact: Delivery timing delays in the Middle East highlight exposure to regional instability, though backlog retention mitigates immediate revenue loss.
- Service Revenue Growth Potential: Recurring service contracts, especially in Security, offer higher-margin revenue streams and greater revenue visibility.
- Contract Visibility and Timing: Large IDIQ contracts with CBP and defense programs provide multi-year revenue streams, but significant revenue recognition is weighted toward fiscal 2028 and beyond.
- Margin Expansion Opportunities: Operational efficiencies, favorable revenue mix, and increased service penetration support ongoing margin improvement across segments.
- Capital Deployment Balance: Share repurchases and debt refinancing enhance shareholder value and financial flexibility but require monitoring for sustained investment capacity.
Risks
Key risks include continued geopolitical instability affecting delivery schedules and bookings, supply chain disruptions, and potential delays in large government contracts. The timing of revenue recognition from multi-year IDIQ awards introduces uncertainty in near-term financial results. Additionally, competitive pressures in security and healthcare markets may impact pricing and margins.
Forward Outlook
For fiscal 2027, OSI Systems provided guidance of:
- Revenues between $1.875 billion and $1.93 billion, reflecting 5% to 8.1% year-over-year growth.
- Non-GAAP diluted earnings per share between $11.13 and $11.49, representing 7.5% to 11% growth.
Management highlighted that growth will be weighted toward the second half of the year, factoring in conservative assumptions on Middle East delivery deferrals and phased contributions from new IDIQ contracts. The company anticipates strong double-digit service revenue growth and continued margin expansion driven by operational leverage and product mix.
Takeaways
Investors should note the following strategic and operational insights from OSI Systems’ fiscal 2026 results:
- Backlog as a Revenue Cushion: The record $1.9 billion backlog, including deferred Middle East orders, provides a buffer against near-term revenue volatility and supports multi-year growth visibility.
- Segment Differentiation and Growth Drivers: While Security faces timing challenges, Optoelectronics and Healthcare segments demonstrate robust demand and margin improvement, reflecting diversified end markets and operational execution.
- Capital Strategy Enhances Shareholder Value: Aggressive share repurchases coupled with strengthened liquidity underline management’s confidence and provide flexibility for growth investments and shareholder returns.
Conclusion
OSI Systems delivered a record fiscal 2026 marked by strong earnings, cash flow, and backlog growth despite geopolitical headwinds impacting revenue timing. The company’s diversified portfolio, strategic contract wins, and disciplined capital allocation position it well for sustained growth and margin expansion in fiscal 2027 and beyond.
