SANTA CLARA, Calif.--(BUSINESS WIRE)--April 27, 2011--Citrix Systems, Inc. (NASDAQ:CTXS) today reported financial results for the first quarter of fiscal 2011 ended March 31, 2011.

FINANCIAL RESULTS

In the first quarter of fiscal 2011, Citrix achieved revenue of $491 million, compared to $414 million in the first quarter of fiscal 2010, representing 18 percent revenue growth.

GAAP Results

Net income for the first quarter of fiscal 2011 was $74 million, or $0.38 per diluted share, compared to $47 million, or $0.25 per diluted share, for the first quarter of 2010.

Non-GAAP Results

Non-GAAP net income in the first quarter of fiscal 2011 was $97 million, or $0.50 per diluted share, compared to $75 million, or $0.40 per diluted share, in the comparable period last year. Non-GAAP net income for both periods excludes the effects of amortization of intangible assets primarily related to business combinations, stock-based compensation expenses, charges recorded in connection with the restructuring program that the company implemented in January 2009 and the tax effects related to those items.

“I’m pleased with our results for the first quarter,” said Mark Templeton, president and chief executive officer for Citrix. “Customer demand was solid across our core SaaS, desktop and networking markets, especially in the Americas and Pacific, supported by large, strategic technical services engagements.

“Clearly, the industry is rapidly moving from “PC era” to “cloud era,” where users are demanding -- and CIOs are embracing -- the consumerization of IT. We’re driving the transition with products that change how people collaborate, how desktops are delivered, and how delivery networks are built.

“This transformation is elevating our presence as a strategic vendor, increasing our engagement with C-level executives, and driving more interest in our virtual computing platform.”

In addition to quarterly financial results, Citrix also announced that its board of directors has authorized it to repurchase up to an additional $500 million of its common stock. As of March 31, 2011, approximately $11.5 million remained for repurchases from previous authorizations.

Use of Non-GAAP Financial Measures

In Citrix’s earnings release, conference call, slide presentation or webcast, Citrix may use or discuss non-GAAP financial measures as defined by SEC Regulation G. The GAAP financial measure most directly comparable to each non-GAAP financial measure used or discussed and a reconciliation of the differences between each non-GAAP financial measure and the comparable GAAP financial measure are included in this press release after the condensed consolidated financial statement or can be found on the Investor Relations page of the Citrix corporate Web site at http://www.citrix.com/investors.

Xen® is a trademark of Citrix Systems, Inc. managed on behalf of Xen.org, and may be registered in the U.S. Patent and Trademark Office and in other countries.

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, charges associated with the Company’s 2009 restructuring program and the related tax effect of those items. 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 operating margins, operating expenses and net income and comparing the Company's financial performance to that of its peer companies and competitors.

Management typically excludes the amounts 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 and certain stock-based compensation expenses and the related tax effects 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 and the related tax effects 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 is generally fixed at the time of grant, 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 charges incurred in conjunction with the Company's 2009 restructuring program, which relate to reductions in headcount and exit costs associated with consolidating certain facilities, are not ongoing costs and, thus, are outside of the normal operations of the Company's business. The Company, therefore, believes that the exclusion of these charges will better help investors and financial analysts understand the Company's operating results and underlying operational trends as compared to prior periods.

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 primarily related to new business combinations, additional charges related to its restructuring program and the related tax effects from financial measures that it releases, and the Company expects to continue to incur stock-based compensation expenses.
