   BLUE COAT REPORTS FINANCIAL RESULTS FOR FOURTH QUARTER AND FISCAL YEAR 2006

    SUNNYVALE, Calif., May 24 /PRNewswire-FirstCall/ -- Blue Coat(R) Systems,
Inc. (Nasdaq: BCSI), the leader in secure content and application delivery,
today announced financial results for its fourth fiscal quarter and fiscal year
ended April 30, 2006. Net revenue for the fourth quarter was $35.9 million, an
increase of 26.5% compared to net revenue of $28.4 million for the same quarter
last year and a slight increase compared to net revenue of $35.5 million in the
prior quarter. For the fiscal year ended April 30, 2006, net revenue was $141.5
million, an increase of 47.1% compared to net revenue of $96.2 million in the
fiscal year ended April 30, 2005.

    On a GAAP basis, the Company reported a net loss of $2.6 million, or $0.19
per diluted share, in the fourth quarter of fiscal 2006 compared to net income
of $2.8 million, or $0.21 per diluted share, in the same quarter last year and
net income of $3.0 million, or $0.20 per diluted share, in the prior quarter.
The net loss in the fourth quarter of fiscal 2006 includes a charge for acquired
in-process R&D of $3.3 million related to the acquisition of Permeo
Technologies, Inc. ("Permeo"), the amortization of intangible assets of
approximately $0.4 million, and approximately $24,000 of stock-based
compensation expense, offset by approximately $0.2 million related to the
reversal of restructuring reserves.

    GAAP net income for the fiscal year ended April 30, 2006 was $8.0 million,
or $0.54 per diluted share, compared to GAAP net income of $5.4 million, or
$0.41 per diluted share, for the fiscal year ended April 30, 2005.

    On a non-GAAP basis, the Company reported net income of $1.0 million, or
$0.07 per diluted share, in the fourth quarter of fiscal 2006 compared to non-
GAAP net income of $2.3 million, or $0.17 per diluted share, in the same quarter
last year and non-GAAP net income of $3.2 million, or $0.21 per diluted share,
in the prior quarter.

    Non-GAAP net income for the fiscal year ended April 30, 2006 was $12.6
million, or $0.86 per diluted share, compared to $7.2 million, or $0.55 per
diluted share, for the fiscal year ended April 30, 2005.

    The non-GAAP financial measures presented above for the fourth quarter of
fiscal 2006 exclude the amortization of intangible assets, stock-based
compensation expense, the reversal of restructuring reserves, and a charge for
acquired in-process R&D. The non-GAAP financial measures for the fiscal year
ended April 30, 2006 also exclude the write-off net of recovery of capitalized
software costs associated with the failed implementation of a forecast system.
For the fourth quarter of fiscal 2005 and the fiscal year ended April 30, 2005,
the non-GAAP financial measures exclude the amortization of intangible assets,
stock-based compensation expense, and the reversal of restructuring reserves.

    Blue Coat ended the quarter with cash, cash equivalents, short-term
investments, and restricted investments totaling $58.5 million, a decrease of
$13.4 million from the prior quarter due primarily to the acquisition of Permeo,
partially offset by cash flow from operations.

    "Our fourth quarter results reflect the slower growth in the proxy appliance
market that we began to see in the previous quarter," said Brian NeSmith,
president and chief executive officer of Blue Coat. "We remain confident in our
ability to maintain leadership in the market for secure content and application
delivery, particularly with the latest addition of MACH5 application
acceleration to our SG platform and the rapid integration of technology from
Permeo."

    Financial Outlook

    For the first fiscal quarter ending July 31, 2006, the Company currently
anticipates net revenue in the range of $36.1 - $36.6 million. GAAP net loss is
expected to be in the range of $2.2 - $2.6 million, or $0.15 - $0.17 per diluted
share. On a non-GAAP basis, which is expected to exclude the amortization of
intangible assets and stock-based compensation expense related to the adoption
of FAS 123R, net income is expected to be between $0.6 - $1.0 million, or
$0.04 - $0.06 per diluted share.



    About Non-GAAP Financial Measures

    Blue Coat uses the non-GAAP financial measures of income discussed above for
internal evaluation and to report the results of its business. These non- GAAP
financial measures include non-GAAP cost of revenue, non-GAAP gross profit,
non-GAAP operating expenses, non-GAAP operating income, non-GAAP net income, and
non-GAAP net income per share data. These measures are not in accordance with,
or an alternative to, GAAP. The measures are intended to supplement GAAP
financial information, and may be different from non-GAAP financial measures
used by other companies. Blue Coat believes that these measures provide useful
information to its management, board of directors and investors regarding its
ongoing operating activities and business trends related to its financial
condition and results of operations. Blue Coat believes that it is useful to
provide investors with information to understand how specific line items in the
statement of operations are affected by certain items, such as the amortization
of intangible assets, the write-off and recovery of capitalized software
associated with the failed implementation of a forecast system, a charge for
acquired in-process R&D, stock-based compensation expense, and the reversal of
restructuring reserves. In addition, the Company's management and board of
directors use certain non-GAAP financial measures in developing operating
budgets and in reviewing the Company's financial results of operations since
items such as the amortization of intangible assets, the write-off and recovery
of capitalized software associated with the failed implementation of a forecast
system, a charge for acquired in-process R&D, stock-based compensation, and the
reversal of restructuring reserves are not considered to impact current resource
allocation decisions. The Company believes that inclusion of these non-GAAP
financial measures provides consistency and comparability with past reports of
financial results. However, investors should be aware that non-GAAP financial
measures have inherent limitations and should be read in conjunction with our
consolidated financial statements prepared in accordance with GAAP.

(1)     Amortization of intangible assets associated with the acquisitions of
        Permeo Technologies, Inc., Cerberian, Inc., and Ositis Software, Inc. in
        March 2006, November 2004 and November 2003, respectively.

(2)     In fiscal Q2 2006 the Company wrote-off $272,000 of capitalized software
        associated with a planning and budgeting system due to the software
        vendor's inability to deliver a functioning product. In fiscal Q3 2006,
        $157,000 was recovered from the software vendor and recognized as a
        benefit resulting in a net write-off for fiscal 2006 of $115,000. Both
        the write-off and recovery are included in general and administrative
        expense in the respective quarter.

(3)     In fiscal Q3 2005 the Company recorded a $1.0 million charge due to a
        stock option modification in a severance agreement with the Company's
        then departing chief financial officer where the exercise period was
        extended beyond the original terms and the vesting of certain options
        was accelerated upon termination. For the twelve months ended April 30,
        2005 stock-based compensation was approximately $991,000, which
        consisted of the $1.0 million charge associated with the aforementioned
        stock modification in fiscal Q3 2005 and expense of approximately
        $736,000 primarily relating to shares issued to former employees of
        Ositis who remained with the Company after the acquisition of Ositis,
        reduced by a benefit of approximately $745,000 in fiscal Q4 2005
        resulting from the partial reversal of the aforementioned stock
        compensation recorded in fiscal Q3 2005 associated with the Company's
        then departing chief financial officer due to the modification of the
        severance agreement. For the quarter and year ended April 30, 2006,
        stock-based compensation primarily related to the amortization of
        deferred compensation associated with the acquisition of Permeo.

(4)     Charge for acquired in-process research and development associated with
        the acquisition of Permeo in March 2006.

(5)     The Company reversed certain restructuring reserves in Q4 of both fiscal
        2005 and 2006 related to decreases in the estimated costs required to
        restore leased facilities to the condition stipulated in the related
        lease agreements.

(6)     For fiscal Q4 2006, diluted EPS for the purpose of reconciling non- GAAP
        to GAAP net income and EPS differs from shares used to calculate diluted
        EPS in our GAAP financial statements since the inclusion of certain
        instruments on a GAAP basis would have been anti-dilutive.
