HAWTHORNE, CA -- 11/07/2006 -- (NASDAQ: OSIS)

--  Revenues of $115.5 million with a Loss of $0.36 Per Diluted Share;
--  Company Reiterates Full Year Revenue and Earnings Guidance;
--  Record Security Bookings of $87 million in the First Quarter;
--  Backlog at All-Time High of Approximately $196 million
    

OSI Systems, Inc. (NASDAQ: OSIS), a vertically integrated provider of specialized electronics for critical applications in industries such as homeland security and healthcare, today announced its operating results for its first quarter ended September 30, 2006.

The Company reported revenues of $115.5 million for the first quarter of fiscal 2007, an increase of 13% from the $101.9 million reported for the first quarter of fiscal 2006. The net loss for the first quarter of fiscal 2007 was $(6.0) million, or $(0.36) per diluted share, compared to a net loss of $(4.2) million, or $(0.26) per diluted share, for the first quarter of fiscal 2006. The first quarter results include a one-time pre-tax charge for in-process research and development of $0.6 million relating to the Company's acquisition of Del Mar Reynolds, a diagnostic cardiology business.

The Company reiterated its previously announced full-year guidance for fiscal 2007. Revenues are expected to be between $535 million and $545 million, representing approximately 18-20% growth over the prior fiscal year. The Company expects fiscal 2007 adjusted earnings per share to be $0.35 to $0.45, excluding one-time charges.

Deepak Chopra, OSI Systems' Chairman and CEO, stated, "We are pleased with the momentum generated by our Security division as represented by the record bookings of $87 million in the first quarter and the Company's backlog which is at an all time high of $196 million. However, we are disappointed with our higher than expected loss for the quarter which was primarily attributable to the softness in the U.S. healthcare market and a change in the product mix."

Mr. Chopra continued, "We anticipate benefiting from the recent introduction of our anesthesia systems into the North American market. The integration of recently acquired Del Mar Reynolds is expected to produce higher than anticipated cost synergies and should positively impact the financial performance of the Company in the second half of the fiscal year. Additionally, we have started an internal initiative to reexamine our existing infrastructure to improve profitability."
