ANNOUNCES DEFINITIVE AGREEMENT TO ACQUIRE CONTINUOUS COMPUTING

HILLSBORO, OR — May 3 , 2011— RadiSys^® Corporation (NASDAQ: RSYS), a leading provider of innovative hardware and software platforms for next generation IP-based wireless, wireline and video networks, announced revenues for the first quarter of $73.6 million, GAAP net loss of $529,000 or $0.02 per share, and non-GAAP net income of $2.2 million or $0.09 per diluted share.

GAAP Results

Non-GAAP Results

Non-GAAP results exclude the impact of amortization of acquired intangible assets, stock-based compensation expense, restructuring charges. A reconciliation of GAAP to non-GAAP results is included in the tables below.

Commenting on the first quarter results and the acquisition, Scott Grout, RadiSys President and CEO stated, “We had higher than anticipated ATCA revenues as well as larger legacy communications revenues enabling us to exceed revenue expectations and come in on the high end of our earnings range for the quarter. We were awarded new ATCA business in a variety of applications including notable wins in IMS and wireless infrastructure. We entered a new geographic market with our full media server solution with application software by closing business with a leading China-based Conferencing Service Provider. We believe it represents a key milestone and an important

growth opportunity for the business. Finally, RadiSys achieved ITAR compliance in the quarter to further expand our thrust into the military and defense markets with our leading platform products.” Mr. Grout went on to say, “We are very excited to bring the talented Continuous Computing team and their high value product portfolio of software and ATCA platforms into the RadiSys family. In addition to a complementary set of ATCA platform solutions, Continuous Computing’s acclaimed Trillium software and SW Professional Service business fits extremely well with our strategy of providing higher value solutions and services to our customers.”

First Quarter Financial Highlights

Acquisition of Continuous Computing

RadiSys announced today that it has entered into a definitive agreement to acquire privately held Continuous Computing Corporation (www.ccpu.com). Continuous Computing develops communications systems consisting of highly integrated ATCA platforms and Trillium protocol software coupled with SW Professional Services to complement their full solution offering. Their key customer applications include 3G and 4G Wireless infrastructure, Small Cell base stations, Traffic Management, Internet Offload and Network Security.

Terms of the Acquisition

Consideration for the acquisition is comprised of approximately $73 million in cash, funded with cash on hand, and 3,666,667 shares of RadiSys common stock. Assuming a stock closing price on May 2, 2011 of $8.69 the stock consideration represents $31.9 million. In addition to the consideration payable at closing, RadiSys will make earn-out payments based on revenues generated by a specified set of Trillium products over a three year period following the closing of the acquisition. In lieu of the earn-out payments, RadiSys has the right to make a one-time payment of cash and/or RadiSys shares with a combined aggregate value of $15 million up to 18 months after the closing date.

The transaction received approval by the Boards of Directors of both companies and is expected to close by the end of June 2011, subject to customary closing conditions, including the issuance of a permit for the offering of securities by the California Department of Corporations or the declaration of effectiveness of a registration statement by the Securities and Exchange Commission and approval by the stockholders of Continuous Computing. Following the transaction, Continuous Computing will become a wholly-owned subsidiary of RadiSys. Jefferies & Company, Inc. acted as exclusive financial advisor to RadiSys on this transaction.

Strategic Rationale

RadiSys believes the acquisition of Continuous Computing has a number of compelling strategic benefits. The acquisition drives further expansion into the high growth LTE, Femto / Small Cell Wireless and DPI markets with high performance ATCA platforms and Trillium software. The acquisition also benefits both companies’ customers with a broader set of solutions that are developed and supported by a global team with greater scale and capability. With over 150 customers, Continuous Computing will provide access to a highly complementary set of customers and add further customer diversification to RadiSys. The acquisition also brings a strong leadership team and a talented group of employees to accelerate and expand the RadiSys’ portfolio of software products and services.

Changes to the RadiSys Senior Leadership Structure

Upon closing of the acquisition, Mike Dagenais, Continuous Computing President and CEO, will become RadiSys’ Chief Executive Officer. Brian Bronson, current Chief Financial Officer of RadiSys will become RadiSys’ President and Chief Financial Officer. Scott Grout, current President and Chief Executive Officer of RadiSys will become Vice Chair of the RadiSys Board of Directors. Mr. Dagenais joined Continuous Computing as President and CEO in December 2006. Prior to that, he was president and CEO of Optical Solutions, Inc., a market leading supplier of fiber to the home access solutions. Mr. Dagenais led Optical Solutions through a period of unprecedented growth, culminating in the successful acquisition of Optical Solutions by Calix Networks, a large telecom equipment supplier focused on access solutions for broadband service delivery. He brings over 25 years of experience in the telecommunications industry, including prior executive and management positions at Convergent Networks, Lucent, and Nortel. Mr. Dagenais has a M.Eng. and a B.Eng. in electrical engineering from Carleton University in Ottawa, Canada.

“I am very excited about the opportunity to lead the combined company as CEO. Joining the assets of both RadiSys and Continuous Computing enables us to provide a broader range of higher value solutions to our customers. The capabilities of the unified company will enable our customers to accelerate their time to market and increase their differentiation and competitive advantage,” said Mike Dagenais, Continuous Computing President and CEO. “At Continuous Computing, we grew revenues over 25% in 2010, and I am excited about the combined revenue and earnings growth opportunities ahead.”

This press release contains forward-looking statements, including statements about the Company’s business strategy, outlook guidance, expectations for the second quarter and the full year of 2011, the proposed acquisition of Continuous Computing, its timing, 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) costs, delays and difficulties related to the proposed acquisition of Continuous Computing, (e) satisfaction of conditions to the closing of the acquisition, (f) actions by regulatory authorities or other third parties, (g) actions by Continuous Computing’s shareholders, (h) the ability of the Company to successfully integrate the business and operations of Continuous Computing, (i) performance and customer acceptance of the Trillium line of products (j) the combined companies’ financial results and performance and (k) 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, 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 May 3, 2011. 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.

Non-GAAP Financial Measures

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) amortization of acquired intangible assets, (b) stock-based compensation expense recognized as a result of the Company’s adoption of FAS 123R (now codified at FASB ASC Topic 718), (c) restructuring charges (reversals), (d) income taxes. 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 tables below. 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.

The Company excludes the following expenses, reversals, gains and losses from its non-GAAP financial measures, when applicable:

(a) Amortization of acquired intangible assets: Amortization of acquisition-related intangible assets primarily relate to core and existing technologies, patents, trade name and customer relationships that were acquired with the acquisition of Convedia, MCPD and Pactolus. The Company excludes the amortization of acquisition-related intangible assets because it does not reflect the Company’s ongoing business and it does not have a direct correlation to the operation of the Company’s business. In addition, in accordance with GAAP, the Company generally recognizes expenses for internally-developed intangible assets as they are incurred, notwithstanding the potential future benefit such assets may provide. Unlike internally-developed intangible assets, however, and also in accordance with GAAP, the Company generally capitalizes the cost of acquired intangible assets and recognizes that cost as an expense over the useful lives of the assets acquired. As a result of their GAAP treatment, there is an inherent lack of comparability between the financial performance of internally-developed intangible assets and acquired intangible assets. Accordingly, the Company believes it is useful to provide, as a supplement to its GAAP operating results, non-GAAP financial measures that exclude the amortization of acquired intangibles in order to enhance the period-over-period comparison of its operating results, as there is significant variability and unpredictability across companies with respect to this expense.

(b) Stock-based compensation: Stock-based compensation consists of expenses recorded under GAAP, in connection with stock awards such as stock options, restricted stock awards and restricted stock units granted under the Company’s equity incentive plans and shares issued pursuant to the Company’s employee stock purchase plan. The Company excludes stock-based compensation from non-GAAP financial measures because it is a non-cash measurement that does not reflect the Company’s ongoing business and because the Company believes that investors want to understand the impact on the Company of the adoption of the applicable GAAP surrounding share based payments; the Company believes that the provision of non-GAAP information that excludes stock-based compensation improves the ability of investors to compare its period-over-period operating results, as there is significant variability and unpredictability across companies with respect to this expense.

(c) Restructuring charges, net: Restructuring primarily relates to activities engaged in by the Company’s management to simplify and focus its infrastructure. Restructuring and other charges are excluded from non-GAAP financial measures because they are not considered core operating activities. Although the Company has engaged in various restructuring activities over the past several years, each has been a discrete event based on a unique set of business objectives. The Company does not engage in restructuring activities in the ordinary course of business. As such, the Company believes it is appropriate to exclude restructuring charges from its non-GAAP financial measures because it enhances the ability of investors to compare the Company’s period-over-period operating results.

(d) Acquisition related charges: We have and in the future plan to exclude the effect of acquisition related charges from our non-GAAP operating expenses and net income measures. We expect to incur significant expenses in connection with our acquisitions and other operating expenses or income, which we generally would not have otherwise incurred in the periods presented as a part of our continuing operations. Acquisition related charges may include transaction fees, legal fees associated with the transaction, personnel related costs for transitional employees, other acquired employee related costs, stock-based compensation expenses (in addition to the stock-based compensation expenses described above), integration related professional services, certain business combination adjustments after the measurement period has ended and certain other operating expenses, net. We believe it is useful for investors to understand the effects of these items on our total operating expenses. Although acquisition related expenses generally diminish over time with respect to past acquisitions, we generally will incur these expenses in connection with any future acquisitions.

(e) Income taxes: Income tax provision/ (benefit) associated with non-GAAP adjustments, which is calculated as the net effect of all non-GAAP financial statement adjustments on the Company’s overall income tax provision/ (benefit).
