Item 2.02.  Results of Operations and Financial Condition.

   The information in this Item 2.02 and the Exhibits attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or any proxy statement or report or other document we may file with the Securities Exchange Commission (“SEC”), regardless of any general incorporation language in any such filing, except as shall be expressly set forth by specific reference in such filing.

   On January 31, 2012, Radisys Corporation (the “Company” or "Radisys") issued a press release announcing its results for the fiscal quarter ended December 31, 2011. A copy of this press release is attached hereto as Exhibit 99.1.

The Company’s press release contains forward-looking statements, including statements about the Company’s business strategy, financial outlook, expectations for the first quarter of 2012 and the full year 2012, and items related to the acquisition of Continuous Computing such as certain royalty revenues, earn-out payments, expected synergies and other expense savings and operational and administrative efficiencies, revenue growth, margin improvement, accretion to earnings, financial performance, management changes and other attributes of the Company following the acquisition.  Actual results could differ materially from the outlook guidance and expectations in these forward-looking statements as a result of a number of risk factors, including, among others, (a) the Company’s dependence on certain customers and high degree of customer concentration, (b) the Company’s use of one contract manufacturer for a significant portion of the production of its products, (c) the anticipated amount and timing of revenues from design wins due to the Company’s customers’ product development time, cancellations or delays, (d) the ability of the Company to successfully integrate the business and operations of Continuous Computing and higher than expected costs of integration, (e) performance and customer acceptance of the Trillium line of products, (f) the combined Company’s financial results and performance and (g) other factors listed in the Company’s reports filed with the Securities and Exchange Commission (SEC), including those listed under “Risk Factors” in Radisys’ Annual Report on Form 10-K for the year ended December 31, 2010 and in Radisys’ subsequent Quarterly Reports on Form 10-Q, copies of which may be obtained by contacting the Company at 503-615-1100, from the Company’s investor relations web site at http://investor.radisys.com/, or at the SEC’s website at http://www.sec.gov.  Although forward-looking statements help provide additional information about Radisys, investors should keep in mind that forward-looking statements are inherently less reliable than historical information.  Should one or more of these risks or uncertainties materialize (or the other consequences of such a development worsen), or should underlying assumptions prove incorrect, actual outcomes may vary materially from those forecasted or expected. All information in this press release is as of January 31, 2012. The Company undertakes no duty to update any forward-looking statement to conform the statement to actual results or changes in the Company’s expectations.    

   To supplement its consolidated financial statements in accordance with generally accepted accounting principles (GAAP), the Company's earnings release contains non-GAAP financial measures that exclude certain expenses, gains and losses, such as the effects of (a) purchase accounting adjustments, (b) amortization of acquired intangible assets, (c) stock-based compensation expense recognized as a result of the Company’s adoption of FAS 123R (now codified at FASB ASC Topic 718), (d) restructuring and acquisition-related charges, net (reversals), (e) gain on the liquidation of a foreign subsidiary, (f) tax contingency adjustments, and (g) income taxes effect of reconciling items. The Company believes that the use of non-GAAP financial measures provides useful information to investors to gain an overall understanding of its current financial performance and its prospects for the future. Specifically, the Company believes the non-GAAP results provide useful information to both management and investors by excluding certain expenses, gains and losses that the Company believes are not indicative of its core operating results. In addition, non-GAAP financial measures are used by management for budgeting and forecasting as well as subsequently measuring the Company's performance, and the Company believes that it is providing investors with financial measures that most closely align to its internal measurement processes. These non-GAAP measures are considered to be reflective of the Company’s core operating results as they more closely reflect the essential revenue-generating activities of the Company and direct operating expenses (resulting in cash expenditures) needed to perform these revenue-generating activities.  The Company also believes, based on feedback provided to the Company during its earnings calls' Q&A sessions and discussions with the investment community, that the non-GAAP financial measures it provides are necessary to allow the investment community to construct their valuation models to better align its results and projections with its competitors and market sector, as there is significant variability and unpredictability across companies with respect to certain expenses, gains and losses.  

   The non-GAAP financial information is presented using consistent methodology from quarter-to-quarter and year-to-year. These measures should be considered in addition to results prepared in accordance with GAAP.  In addition, these non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles. The Company believes that non-GAAP financial measures have limitations in that they do not reflect all of the amounts associated with the Company's results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate the Company's results of operations in conjunction with the corresponding GAAP financial measures.

   A reconciliation of non-GAAP information to GAAP information is included in the table set forth in the press release.   The non-GAAP financial measures disclosed by the Company should not be considered a substitute for or superior to financial measures calculated in accordance with GAAP, and reconciliations between GAAP and non-GAAP financial measures included in this earnings release should be carefully evaluated.  The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.
