      Citrix Reports Fourth Quarter and Fiscal Year 2006 Results

     Year-over-year Quarterly Revenue Growth of 19% Annual Revenue
                             Growth of 25%

    FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Jan. 23, 2007--Citrix
Systems, Inc. (Nasdaq:CTXS), the global leader in application delivery
infrastructure, today reported preliminary financial results for the
fourth quarter and fiscal year ended December 31, 2006.

    Preliminary Financial Results

    In the fourth quarter of fiscal 2006, Citrix achieved revenue of
$321 million, compared to $269 million in the fourth quarter of fiscal
2005, representing 19 percent revenue growth. Annual revenues for 2006
were $1.134 billion, compared to $909 million in the previous year, a
25 percent increase.

    GAAP Results

    Net income for the fourth quarter of fiscal 2006 was $59 million,
or $0.32 per diluted share, flat compared to the fourth quarter of
fiscal 2005. Annual net income for 2006 was $196 million, or $1.05 per
diluted share, compared to $166 million, or $0.93 per diluted share in
fiscal 2005.

    Non-GAAP Results

    Non-GAAP net income, in the fourth quarter of 2006 increased by
nine percent to $73 million, or $0.39 per diluted share, compared to
$67 million, or $0.36 per diluted share, in the comparable period last
year. Non-GAAP net income excludes the effects of amortization of
intangible assets primarily related to business combinations,
stock-based compensation expenses, and the tax effects related to
those items.

    Annual non-GAAP net income for 2006 was $262 million, or $1.40 per
diluted share, compared to $209 million, or $1.17 per diluted share,
in 2005. Non-GAAP net income excludes the effects of amortization of
intangible assets primarily related to business combinations,
stock-based compensation expenses, the write-off of in-process
research and development (IPR&D) and the tax effects related to those
items. In addition, in 2005 non-GAAP net income also excludes the tax
provision related to the repatriation of foreign earnings under the
American Jobs Creation Act (AJCA).

    "A strong finish to another very strong year of growth," said Mark
Templeton, Citrix president and chief executive officer. "We've built
excellent momentum in each of our businesses, and I believe we're
entering 2007 with the best product pipeline, channel partnerships,
and brand strength we've ever had. We're well-positioned for continued
growth as we lead the formation of the application delivery market."

    Stock Option Review

    During the quarter, the Audit Committee of the company's Board of
Directors began a voluntary review of the company's historical stock
option granting practices and the related accounting. This voluntary
review was initiated in light of news about the option practices of
numerous companies across several industries and not in response to
any governmental investigation, whistleblower complaint or inquiries
from media organizations. The Audit Committee has engaged independent
outside legal counsel to conduct the review.

    Because this review is ongoing, the company has not yet determined
if it will need to record any non-cash adjustments to compensation
expense related to prior stock option grants, making today's results
preliminary. Specifically, the company does not know whether any such
non-cash compensation charges would affect the preliminary financial
results for the fourth quarter ended December 31, 2006 or the full
year 2006 being announced today, or would be deemed material and
require the company to restate previously issued financial statements
or would require an adjustment to the retained earnings balance on the
company's balance sheet. If any such charges are required, Citrix will
also need to determine the impact of this matter on its system of
internal controls.

   Reconciliation of Non-GAAP Financial Measures to Comparable U.S.
                       GAAP Measures (Unaudited)

    Pursuant to the requirements of Regulation G, the company has
provided a reconciliation of each non-GAAP financial measure used in
this earnings release and related conference call, slide presentation
or webcast to the most directly comparable GAAP financial measure.
These measures differ from GAAP in that they exclude amortization
primarily related to business combinations, stock-based compensation
expenses, the write-off of in-process research and development and for
2005, a non-recurring tax provision related to the repatriation of
foreign earnings under the AJCA. The company's basis for these
adjustments is described below.

    Management uses these non-GAAP measures for internal reporting and
forecasting purposes, when publicly providing its business outlook, to
evaluate the company's performance and to evaluate and compensate the
company's executives. The company has provided these non-GAAP
financial measures in addition to GAAP financial results because it
believes that these non-GAAP financial measures provide useful
information to certain investors and financial analysts for comparison
across accounting periods not influenced by certain non-cash items
that are not used by management when evaluating the company's
historical and prospective financial performance. In addition, the
company has historically provided this or similar information and
understands that some investors and financial analysts find this
information helpful in analyzing the company's gross margins,
operating expenses and net income and comparing the company's
financial performance to that of its peer companies and competitors.

    Management excludes the expenses described above when evaluating
the company's operating performance and believes that the resulting
non-GAAP measures are useful to investors and financial analysts in
assessing the company's operating performance due to the following
factors:

    --  The company does not acquire businesses on a predictable
        cycle. The company, therefore, believes that the presentation
        of non-GAAP measures that adjust for the impact of
        amortization, in-process research and development and certain
        stock-based compensation expenses that are primarily related
        to business combinations, provide investors and financial
        analysts with a consistent basis for comparison across
        accounting periods and, therefore, are useful to investors and
        financial analysts in helping them to better understand the
        company's operating results and underlying operational trends.

    --  Amortization costs are fixed at the time of an acquisition,
        are then amortized over a period of several years after the
        acquisition and generally cannot be changed or influenced by
        management after the acquisition.

    --  Although stock-based compensation is an important aspect of
        the compensation of the company's employees and executives,
        stock-based compensation expense and its related tax impact
        are generally fixed at the time of grant, are then amortized
        over a period of several years after the grant of the
        stock-based instrument and generally cannot be changed or
        influenced by management after the grant.

    --  The company considers the 2005 tax provision related to the
        repatriation of certain foreign earnings under the AJCA as
        non-recurring as it is not reasonably likely to recur within
        two years and there was no similar provision in the prior two
        years. The company, therefore, believes that the presentation
        of non-GAAP measures that adjust for the impact of this tax
        provision provides investors and financial analysts with a
        consistent basis for comparison across accounting periods and,
        therefore, are useful to investors and financial analysts in
        helping them to better understand the company's operating
        results and underlying operational trends.

    These non-GAAP financial measures are not prepared in accordance
with accounting principles generally accepted in the United States
("GAAP") and may differ from the non-GAAP information used by other
companies. There are significant limitations associated with the use
of non-GAAP financial measures. The additional non-GAAP financial
information presented here should be considered in conjunction with,
and not as a substitute for or superior to, the financial information
presented in accordance with GAAP (such as net income and earnings per
share) and should not be considered measures of the company's
liquidity. Furthermore, the company in the future may exclude
amortization and in-process research and development primarily related
to new business combinations from financial measures that it releases,
and the company expects to continue to incur stock-based compensation
expenses.
