HAWTHORNE, Calif. — (BUSINESS WIRE) — August 20, 2026 — OSI Systems, Inc. (the “Company” or “OSI Systems”) (NASDAQ: OSIS) today announced its financial results for the three months and fiscal year ended June 30, 2026.

Ajay Mehra, OSI Systems’ President and Chief Executive Officer, stated, “Fiscal 2026 was a strong year for the Company, capped by record fourth quarter non-GAAP earnings per share and record operating cash flow, despite the impact of revenue headwinds from the Middle East conflicts which shifted the timing of certain planned deliveries. Our teams performed well across our three divisions, delivering solid bookings which led to substantial backlog. As we enter fiscal 2027, our opportunity pipeline, disciplined operating execution and continued focus on cash generation position us well to advance key strategic initiatives and drive long-term value.”

The Company’s backlog was approximately $1.9 billion as of June 30, 2026 compared to $1.8 billion a year ago.

Mr. Mehra added, "The Security division continued to execute well during the fourth quarter, delivering strong profitability, outstanding cash generation and healthy bookings. While revenues were impacted by disruptions from the Middle East conflicts, underlying demand for our products and services remain encouraging. These delays do not reflect order cancellations and remain in our backlog with updated delivery schedules. The Security division ended the year with a substantial backlog, a significant opportunity pipeline and recent program wins that position the business well for the future.”

Mr. Mehra continued, “The Optoelectronics and Manufacturing division delivered strong results for the quarter with revenues up about 5% year-over-year on broad-based demand across several key end markets. Our ability to support customers with highly engineered products, precision manufacturing capabilities and global operational reach continues to differentiate us in the marketplace. We are excited by the opportunities we see across our aerospace, defense, healthcare, technology and industrial Optoelectronics customer base.”

Mr. Mehra further added, “The Healthcare division delivered an improved fourth quarter, with revenues up approximately 5% and an adjusted operating margin of 10% compared with 1% in the prior-year quarter, demonstrating the impact of operational improvements implemented throughout the year. We are focused on expanding our installed base, supporting healthcare providers with innovative clinical solutions and advancing product development initiatives designed to enhance patient care.”

The Company repurchased 564,880 shares during the fiscal 2026 fourth quarter for an aggregate cash amount of $123.6 million. The Company ended fiscal 2026 with $359.8 million of cash and cash equivalents, up from $106.4 million a year earlier. During fiscal 2026, the Company refinanced and expanded its long-term debt, extended maturities, enhanced financial flexibility to fund growth initiatives, and reduced bank lines of credit to zero while continuing to return capital to shareholders through stock repurchases.

(Dollars in thousands, except per-share amounts) 2025 2026 % Growth 2025 2026 % Growth

Revenues $444,354 $453,246 2% $1,208,181 1,301,926 8%

$17,713 $21,272

The Company’s backlog was approximately $1.9 billion as of March 31, 2026, compared to approximately $1.8 billion as of December 31, 2025 reflecting continued strong bookings momentum across the Security and Optoelectronics and Manufacturing divisions.

Mr. Mehra added, “The Security division delivered another solid quarter supported by disciplined execution, strong bookings and operating margin expansion despite a challenging year-over-year comparison due to significant Mexico revenues in the third quarter of fiscal year 2025. Excluding these Mexico contracts, the Security division’s revenues increased by 25% year-over-year across the broader portfolio. In addition, we are pleased with recent notable awards and look forward to capturing other significant global opportunities.”

Mr. Mehra continued, “The Optoelectronics and Manufacturing division also produced solid third quarter results, with 10% revenue growth and a strong book-to-bill ratio. These results continue to reinforce the advantages of our vertically integrated global operating model, which provides efficiency and flexibility to serve our diverse OEM customer base across aerospace, defense, healthcare and consumer technologies.”

Fiscal Year 2026 Outlook

The Company is reiterating its fiscal 2026 revenue guidance range of $1.825 billion to $1.867 billion and its non-GAAP diluted earnings per share guidance range of $10.30 to $10.55. Actual revenues and non-GAAP diluted earnings per share could vary from this guidance due to factors discussed under “Forward-Looking Statements” or other factors, including the impact on near-term bookings and revenues of the recent shutdown of the Department of Homeland Security and current conflicts in the Middle East.

The Company’s fiscal 2026 diluted earnings per share guidance is provided on a non-GAAP basis only. The Company does not provide a reconciliation of guidance for non-GAAP diluted EPS to GAAP diluted EPS (the most directly comparable GAAP measure) on a forward-looking basis because the Company is unable to provide a meaningful or accurate compilation of reconciling items and certain information is not available. This is due to the inherent difficulty and complexity in accurately forecasting the timing and amounts of various items included in the calculation of GAAP diluted EPS but excluded in the calculation of non-GAAP diluted EPS, such as acquisition costs and other non-recurring items that have not yet occurred, are out of the Company’s control or cannot otherwise reasonably be predicted. For the same reasons, the Company is unable to address the significance of unavailable information which may be material and therefore could result in GAAP diluted EPS being materially different from projected non-GAAP diluted EPS.
