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 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 October 27, 2005, RadiSys Corporation (the “Company”) issued a press release announcing its results for the fiscal quarter ending September 30, 2005. A copy of this press release is attached hereto as Exhibit 99.1. Additionally, on October 27, 2005, the Company held a conference call discussing its results for the fiscal quarter ending September 30, 2005. A copy of the text of this conference call is attached hereto as Exhibit 99.2.

     The press release and the text of the conference call contains forward-looking statements, including the statements about the (i) Company’s guidance for the fourth quarter, particularly with respect to anticipated revenues and diluted earnings per share, (ii) anticipated amount and timing of the increase in research and development spending in the fourth quarter, (iii) the effects on our revenues and business resulting from new design wins and the timing of such effects, and (iv) the increase in future business activities resulting from increases in research and development activities. Actual results could differ materially from our guidance in these forward-looking statements as a result of a number of risk factors described in the press release and other risk factors listed from time to time in the Company’s SEC reports, including those listed under “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004, and in the Company’s 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’s at 503-615-1100 or at the Company’s investor relations website at http://www.radisys.com.

     The conference call contained the following sentence that may be considered to have non-GAAP Financial Information as contemplated by SEC Regulation G, Rule 100:

     ” Operating expenses excluding intangible amortization and restructuring reversals totaled $15.5 million this quarter, about even with the second quarter. “

     Accordingly, we are providing the following table, which reconciles the information to the corresponding GAAP-based measure represented in our Consolidated Statements of Operations in the accompanying press release. Management believes the presentation of this non-GAAP financial measure, in connection with the results of the fiscal quarter and year ended September 30, 2005, provides useful information to investors regarding our results of operations as this non-GAAP financial measure allows investors to better evaluate ongoing business performance and factors that influenced performance during the period under report. Management also uses this non-GAAP measure internally to monitor performance of business. This non-GAAP financial measure should be considered in addition to, and not as a substitute for, financial measures prepared in accordance with GAAP.

Reconciliation of reported operating expenses to GAAP operating expenses (in thousands):

	Three Months Ended
	September 30, 2005			June 30, 2005
Operating Expenses (GAAP):	$	15,389		$	16,659
