RADISYS ANNOUNCES THIRD QUARTER RESULTS -REVENUE OF $81.4 MILLION, UP 9% YEAR OVER YEAR

HILLSBORO, OR — October 26, 2006 — RadiSysÒ Corporation (Nasdaq: RSYS), a leading global provider of advanced embedded solutions, reported revenues of $81.4 million for the quarter ended September 30, 2006. As a result of acquisition related expenses, the third quarter GAAP loss was $13.3 million or $0.62 per share. Non-GAAP net income for the third quarter was $4.6 million or $0.18 per diluted share. Non-GAAP net income excludes the effect of Convedia-related acquisition expenses and stock-based compensation expense. Non-GAAP results include a loss before taxes of $0.2 million or $0.01 per diluted share for one month of Convedia results and exclude $0.5 million or $0.02 per diluted share of interest income forfeited on the cash used for the acquisition. These items, along with a favorable tax rate change of $0.04 per diluted share were not included in the Company’s previously issued third quarter guidance.

Commenting on the results for the quarter, Scott Grout, President and CEO stated, “Our third quarter financial results were in line with our expectations and while we currently project double digit annual revenue growth for the full year over 2005, we do expect to see a significant revenue decrease in the fourth quarter as our quarterly demand from a large wireless customer continues to be volatile although up in total over 2005. We expect this decrease to be partially offset by an increase in our other markets. We continue to make excellent progress on closing future business with our new products. We were awarded new business in both our Promentum and Procelerant product lines in applications that include IPTV, XML routing servers and medical imaging. Our cumulative design wins, since the first quarter of 2005, are now estimated to range from $550 to $650 million. These design wins include projected business with over 50 new customers in a wide range of compelling new applications. The cumulative design win estimates are based on projected revenues in the first three years of our customers’ deployment. Given the nature of these customer programs, the amount and timing of meaningful deployments cannot be certain, but we do expect to see growth in deployments starting towards the end of 2007 and into 2008. About two thirds of the cumulative design wins are from our Promentum ATCA product line and about one third is from our Procelerant product line and other new products. I continue to be very pleased with our design win performance and the overall market acceptance of our products.”

The Company announced earlier this month the expansion of their market leading ATCA and AMC family of products with the introduction of two new products based on the latest OCTEON processors from Cavium Networks. The new ATCA and AMC solutions provide high density Gigabit Ethernet interfaces with sophisticated dataplane hardware acceleration. These products will help equipment manufacturers reduce research and development costs while accelerating the introduction of high performance products such as Radio Network Controllers, Session Border Controllers, Media Gateways, Edge Routers and Security Gateways. The Company’s new AMC-7211 product provides power efficient, packet and security processing for customers requiring AMC modules for their ATCA and uTCA platforms.

On September 1, 2006, the Company announced that it had completed the acquisition of Convedia Corporation, the leading provider of media processing platforms to communications equipment providers. Commenting on the acquisition, Scott Grout said, “Integration efforts are well underway, and I am very pleased with our progress. Integration is proceeding to plan, and we believe we are successfully laying the foundation for strong unified business operations. As stated earlier, we view this acquisition as a meaningful strategic accelerator for RadiSys that will expand our platform business as well as broaden our base of products and core technologies. Convedia’s clear market leadership in IP media processing in the emerging IMS and VoIP markets together with our leadership in ATCA will help to create a broader and more compelling portfolio of customer solutions for an expanded addressable market. Media server revenue growth over the next couple of quarters will be largely dependent on TEM’s moving from current generation, TDM media processing platforms, to IP-enabled IMS infrastructure, particularly in China as 3G licenses are awarded and 3G networks are rolled out. We currently expect the acquisition to become accretive on a non-GAAP basis, excluding the effect of Convedia-related acquisition expenses and stock-based compensation expense, in the second half of 2007.”

In addition, the Company announced today, in a separate press release, the appointment of Julia A. Harper to a new role of Vice President, Corporate Operations and the appointment of Brian Bronson to Chief Financial Officer of the Company.

Fourth Quarter 2006 Outlook

The following statements are based on current expectations as of the date of this press release. These statements are forward-looking, and actual results may differ materially. The Company assumes no obligation to update these statements.

Commenting on the outlook, Scott Grout stated, “We expect revenues in the fourth quarter to be between $57 and $63 million. The projected decrease in fourth quarter revenue is due to recent reductions in requested deliveries from a large wireless customer. We believe these reductions are driven by their efforts to significantly reduce inventory levels, including buffer inventories that were used to support a successful RoHS conversion, as well as lowered demand projections for systems into which we supply content. We do not believe there is a fundamental change in our wireless business and currently project revenues to return to higher levels in 2007, although they will continue to vary quarterly. While I am disappointed in the expected sequential decline, the mid-point of our revenue guidance for the fourth quarter will bring us to annual GAAP revenue for 2006 of $292 million versus $260 million in 2005. This represents revenue growth of 12% year over year for the Company. As you recall, at the beginning of the year, our expectation was to deliver modest revenue growth for 2006 over 2005 and while our quarterly revenues have varied, we do expect to deliver double-digit growth for the year which is better than our expectations at the beginning of the year. We currently expect fourth quarter GAAP results to be a loss in the range of $0.33 to $0.28 per share, and we expect our non-GAAP results to be a loss in the range of $0.09 to $0.04 per share. Our non-GAAP expected results exclude a loss of approximately $0.24 per share primarily attributable to the impact of Convedia-related acquisition expenses and stock-based compensation expense.”

In closing, Mr. Grout stated, “While I’m disappointed with the projections for the fourth quarter, I’m pleased with the expected results for the full year and excited by our continued meaningful design win traction that we believe will fuel growth going forward. We believe that the market acceptance and enthusiasm around our new products remains strong and that our solutions are enabling our customers to bring better products to market faster and at a lower total cost.”

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, (a) the amount of stock-based compensation expense, (b) the anticipated amount and timing of revenues from new business, (c) that we may not be able to successfully integrate operations, technologies, products or personnel from the acquisition of Convedia Corporation, (d) that we may not realize the benefits we are seeking from the acquisition of Convedia Corporation and such acquisition may be more costly or less profitable than anticipated and may adversely affect the price of our stock, and (e) the factors listed in RadiSys’ SEC reports, including those listed under “Risk Factors” in RadiSys’ Annual Report on Form 10-K for the year ended December 31, 2005, and in the RadiSys Quarterly Reports on Form 10-Q filed with the SEC each fiscal quarter, and other filings with the SEC, copies of which may be obtained by contacting the Company at 503-615-1100 or from the Company’s investor relations web site at http://investor.radisys.com/. 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. All information in this press release is as of October 26, 2006. 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.

Use of Non-GAAP Financial Measures

In addition to disclosing financial results calculated in accordance with GAAP, the historical and forward-looking financial results in the Company’s earnings release contain non-GAAP financial measures that exclude the effects of (a) Convedia acquisition-related expenses including an in-process R&D charge, amortization of acquired intangible assets, amortization of deferred compensation, integration expenses and purchase accounting adjustments, (b) stock-based compensation expense recognized as a result of the Company’s adoption of FAS 123R, (c) restructuring charges (reversals), (d) insurance gains, and (e) gains related to class action litigation. The Company believes that the presentation of results excluding these items will provide meaningful supplemental information to investors that are indicative of the Company’s core operating results. 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 by other companies.
