OSIS Q4 Revenue Misses on Middle East Delays, but Record Backlog and New Contracts Support Outlook
Q4 revenue miss and soft FY27 guidance OSI Systems reported Q4 revenue of $484.1 million, down 4.1% and missing estimates by 8.4%, as about $50 million of Security deliveries slipped past fiscal year-end due to Middle East conflict delays. FY27 revenue guidance of $1.875–$1.93 billion came in below the $1.94 billion consensus, sending shares down sharply.
This is the main new negative event that directly explains the stock's recent drop and answers what is driving OSIS now.
Record backlog and new U.S. Customs contracts Despite the revenue miss, backlog hit a record $1.90 billion, up 5.6% year over year. After fiscal year-end, U.S. Customs and Border Protection awarded two five-year contracts worth up to $200 million and $85 million for vehicle and mobile X-ray inspection systems, supporting future growth.
This is new information that provides a positive counterweight to the revenue miss and supports the long-term demand story.
Earnings beat on margin gains and strong cash flow Q4 adjusted EPS of $3.78 beat estimates and rose 16.7% year over year, helped by margin gains. The company also reported record Q4 operating cash flow of $182 million and record full-year cash flow of $276 million, showing the business remains profitable and cash-generative.
This new positive detail explains why the stock did not fall further and highlights underlying financial health.
Healthcare and optoelectronics offset Security weakness Security division revenue fell 7.4% to $339.7 million, missing estimates, but healthcare revenue rose 4.8% to $44.8 million and optoelectronics revenue rose 4.6% to $117.8 million, both beating expectations. This diversification softens the blow from the Security shortfall.
This new segment detail shows the revenue miss was concentrated in one division, giving a fair picture of the drivers.
