                                                                    Exhibit 99.1

       OSI Systems Reports Fourth Quarter and Fiscal Year 2007
                          Financial Results

    HAWTHORNE, Calif.--(BUSINESS WIRE)--Sept. 5, 2007--OSI Systems,
Inc. (NASDAQ:OSIS) today announced financial results for its fourth
quarter and fiscal year ended June 30, 2007.

    The Company reported record revenues of $152.8 million for the
fourth quarter of fiscal 2007, an increase of 22% from the $125.6
million reported for the fourth quarter of fiscal 2006. Net income for
the fourth quarter of fiscal 2007 was $4.3 million, or $0.24 per
diluted share, compared to net income of $0.7 million, or $0.04 per
diluted share, for the fourth quarter of fiscal 2006.

    For the fiscal year ended June 30, 2007, revenues increased by
$79.6 million, or 18%, to $532.3 million from $452.7 million for
fiscal 2006. For fiscal 2007, the Company reported a net loss of $18.8
million or $(1.12) per diluted share, compared to a net loss of $2.4
million or $(0.17) per diluted share, in fiscal 2006.

    The financial results for the fourth quarter of fiscal 2007 were
adversely impacted by impairment, restructuring and other charges of
$2.3 million. These charges were primarily related to the Company's
previously announced plan to generate approximately $17 million of
pre-tax annualized cost savings through the integration of recent
acquisitions and the rationalization of the Company's cost structure,
the full benefit of which is expected to be realized in fiscal 2008.
In addition, the fourth quarter results included a $1.6 million
operating loss attributable to a business within the Company's
Optoelectronics and Manufacturing division that manufactures and sells
weapons simulation systems. The financial results for the fourth
quarter of fiscal 2007 were favorably impacted by a $1.3 million tax
benefit.

    The financial results for the year ended June 30, 2007 included
impairment, restructuring and other charges of approximately $36.9
million. These charges were primarily associated with the Company's
determination that certain fixed and intangible assets were impaired
as well as the recording of $10.3 million of additional inventory
reserves, which reserves are included in cost of goods sold. In
addition, the fiscal 2007 results included a $4.6 million operating
loss attributable to the aforementioned weapons simulation business.
The fiscal 2007 financial results were favorably impacted by the
settlement of a dispute with GE Healthcare related to the Company's
acquisition of Spacelabs Medical in fiscal 2004. The settlement
resulted in the receipt of $15.0 million, which amount has been
recorded as other income.

    The Company maintained its record backlog level of $209 million as
of June 30, 2007 while reporting record revenues for the fourth
quarter. The continued record backlog level was primarily a result of
the continued strong performance of our Security division which
reported a backlog of approximately $117 million as of June 30, 2007.

    Deepak Chopra, OSI Systems Chairman and CEO, said, "We are
encouraged by our performance in the fourth quarter. We were able to
make progress on several critical initiatives including regaining top
line momentum in our Healthcare division and continued strong security
bookings. We continue to see exciting opportunities within each of our
divisions as evidenced by our record revenue and strong backlog levels
at the end of the fiscal year."

    Mr. Chopra continued, "Fiscal 2007 can be characterized as a
transition year for the Company. We are committed to making the
necessary changes to improve our bottom line performance. Recently we
announced that we had completed the implementation of cost cutting
measures to generate approximately $17 million of annualized savings
and further identified an additional $2 - $3 million of cost savings
we expect to implement in the first half of fiscal 2008. While these
measures look to improve our operating performance, we are also
increasing our focus on our core operations. To that end, we are
reviewing strategic options for our weapon simulation business to
eradicate the losses experienced in the past fiscal year."

    Mr. Chopra concluded, "We enter fiscal 2008 with a tremendous
amount of top-line momentum supported by strong industry-wide trends
affecting our Security and Healthcare divisions and our continued
commitment to R&D. During fiscal 2007 we successfully launched a
number of new products while continuing to invest heavily in next
generation products that we believe will have a significant impact on
our business and market position in the near future. Overall, we
remain focused on delivering improved financial results to our
shareholders."

    Forward-Looking Guidance for Fiscal 2008

    The Company has not previously issued guidance for fiscal 2008.
Subject to Safe Harbor statement below the Company provided its
expectations for fiscal 2008 as follows:

    Fiscal 2008

    --  Net sales of $580 - $595 million, or year-over-year growth of
        9 - 12%.

    Fiscal 2008 - First Quarter

    --  Net sales of $125 - $130 million, or year-over-year growth of
        8 - 13%. The Company expects to report a net loss in the first
        quarter with the loss per share expected to be significantly
        reduced from the ($0.36) per share loss reported in the first
        quarter of fiscal 2007. The first quarter, historically the
        weakest quarter in the Company's fiscal year, is impacted by
        seasonality factors within the Security and Healthcare
        divisions.

    Alan Edrick, OSI Systems, Inc.'s Executive Vice President and
Chief Financial Officer said, "Although we improved our financial
performance in the fourth quarter of 2007, we still have work ahead of
us to accelerate organic growth, improve operating margins and
generate free cash flow. However, we believe the decisions we made in
fiscal 2007 to aggressively reduce our cost base together with the
plans under development for the balance of our portfolio will enable
us to capitalize on the strength of our brands to maximize shareholder
value."
