OSI Systems Expects Net Loss for the Third Quarter

OSI Systems Expects Net Loss for the Third QuarterOSI Systems, Inc. (Nasdaq:OSIS) today announced that it is expecting a net loss for the third quarter of fiscal 2005 of approximately $2.8 million to $3.2 million, or $0.17 to $0.19 per share after Spacelabs-related retention and amortization expenses of approximately $0.04 per share.

For the third quarter, despite lower than expected revenues for the Healthcare segment, all business segments are expected to achieve operating profits with the exception of the Security segment. The Security segment was impacted by both the establishment of a $2.5 million ($1.6 million after tax) bad debt reserve for an international Cargo and Vehicle Inspection receivable and higher than expected operating losses attributable to the Cargo and Vehicle Inspection product line. Additionally, the company also incurred higher than forecasted litigation and Sarbanes-Oxley implementation expenses of approximately $900,000 ($560,000 after tax). These charges were offset by a tax benefit of approximately $626,000 from the favorable resolution of a tax contingency.

The company expects revenue for the third quarter of fiscal 2005 to be approximately $94 million. Revenue for the quarter included approximately $2.6 million of revenue from Blease Medical Holdings which was acquired in February 2005.

The company will provide further details with the release of the third quarter results on Wednesday May 4, 2005.
