Overview

We have shifted more of our investments from predominantly perfect fit (custom) solutions to standards-based solutions. We believe standards-based solutions provide our customers a number of fundamental benefits. First, by using ready-made platform solutions rather than ground-start custom-designs, our customers can achieve significantly shorter product intervals and faster time-to-market. Second, we believe our customers can achieve a lower total cost by using solutions that are leveraged across multiple applications rather than a single-use proprietary solution. By offering ready-made solutions, we believe we have the opportunity to address a wider range of new market opportunities with the potential for faster time to revenue than with ground-start, custom-designs. We believe this ability to reuse designs makes our business and investment model more scalable. Finally, we believe a more standards-based product model will allow us to provide more integrated higher value solutions to our customers than we have typically delivered under a custom-design model. These higher value solutions drive higher price points and therefore more total revenue opportunities for our products.

Financial Results-Total revenue was $372.6 million, $325.2 million and $292.5 million in 2008, 2007 and 2006, respectively. Backlog was approximately $34.4 million, $33.8 million and $21.7 million at December 31, 2008, 2007 and 2006, respectively. Backlog includes all purchase orders scheduled for delivery within 12 months. The increase in revenues during 2008 compared to 2007 was due to increases in revenues in the communications networking market of $45.4 million along with increased revenues of $2.0 million in the commercial systems market. The increase in revenues during 2007 compared to 2006 was due to increases in revenues in the communications networking and commercial systems markets of $29.5 million and $3.3 million, respectively. Revenues in the communications networking market increased from 2007 to 2008 primarily due to increases in next generation communication revenues from our Intel MCPD acquisition, for which a full year of revenues were realized, as well as increases in revenues from organic ATCA and media server products. Revenues in the commercial systems market increased slightly during 2008 compared to 2007, primarily due to increases within the other commercial submarket, which was partially offset by declines in revenues from the test and measurement and medical submarkets.

From a geographic perspective, from 2007 to 2008 non-U.S. revenues by delivery destination increased by $32.1 million. Specifically, revenues from the Asia Pacific region increased by $26.2 million in 2008 and represented 30.5% of total revenues, up from 26.8% in 2007. Additionally, revenues from the EMEA region increased $5.9 million and represented 37.0% of total revenues, down from 40.6% in 2007. Increased revenues in both the Asia Pacific and EMEA regions were driven by the addition of Asian Pacific and European customer revenues resulting from our MCPD acquisition. Increased sales to Nokia Siemens Networks further contributed to these increases. For the year ended December 31, 2008 revenues from North America increased by $15.3 million as compared to the same period in 2007, but remained flat as a percent of total revenues. The increase was due primarily to the addition of revenues from our MCPD acquisition as well as increased media server revenues.

Gross margins as a percentage of revenues were 25.8%, 22.1% and 27.0% for 2008, 2007 and 2006, respectively. The increase in gross margin as a percentage of revenues for the year ended December 31, 2008 compared to the same period in 2007 was primarily attributable to an increased mix of revenues from higher margin next generation communication products. This increase was further driven by operational improvements leading to lower excess and obsolete charges as well as increased leverage of fixed costs. In addition, gross margin improved favorably due to the absence of significant charges associated with the transition from our North Carolina manufacturer, which occurred in 2007.

During the year ended December 31, 2008, we also incurred a $67.3 million charge associated with the full impairment of our goodwill balances. A decline in our share price, during the fourth quarter of 2008, was considered a triggering event, which prompted us to perform an impairment analysis that ultimately led to the impairment charge. The charge was the result of our book value exceeding our fair value.

Net loss was $66.0 million, $17.6 million, $13.0 million in 2008, 2007 and 2006, respectively. Net loss per share was $2.92, $0.80 and $0.62 for 2008, 2007 and 2006, respectively. The net loss increased from 2007 to 2008, due primarily to the goodwill impairment charge totaling $67.3 million.

Cash and cash equivalents amounted to $74.0 million and $50.5 million at December 31, 2008 and December 31, 2007, respectively. The increase in cash and cash equivalents was primarily due to operating cash flows in the amount of $34.9 million, which were partially offset by cash outflows for financing in the amount of $15.1 million. Financing cash outflows were driven by repurchases of our convertible debt and offset partially by new borrowings on our revolving line of credit. Our investments totaled $72.8 million at December 31, 2007 and $62.3 million at December 31, 2008, which includes our ARS settlement right. The decrease is primarily due to sales of ARS in the first quarter of 2008.

In the following discussion of our financial condition and results of operations, we intend to provide information that will assist in understanding our financial statements, changes in certain key items in those financial statements from year to year, and the primary factors that accounted for those changes, as well as how certain accounting principles, policies and estimates affect our financial statements.

Critical Accounting Policies and Estimates

Management's discussion and analysis of our financial condition and results of operations are based upon the Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make estimates and judgments that may affect the reported amounts of assets, liabilities, and revenues and expenses. On an on-going basis, management evaluates its estimates. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. Management believes the following critical accounting policies reflect the more significant estimates and assumptions used in the preparation of the Consolidated Financial Statements.

Inventory Valuation

We record the inventory valuation allowance for estimated obsolete or unmarketable inventories as the difference between the cost of inventories and the estimated net realizable value based upon assumptions about future demand and market conditions. Pursuant to ARB 43 and SAB Topic 5-BB, our inventory valuation allowances establish a new cost basis for inventory. Factors influencing the provision include: changes in demand; rapid technological changes; product life cycle and development plans; component cost trends; product pricing; regulatory requirements affecting components; and physical deterioration. If actual market conditions are less favorable than those projected by management, additional provisions for inventory reserves may be required. Our estimate for the allowance is based on the assumption that our customers comply with their current contractual obligations. We provide long-life support to our customers and therefore we have material levels of customer specific inventory. If our customers experience a financial hardship or if we experience unplanned cancellations of customer contracts, the current provision for the inventory reserves may be inadequate. Additionally, we may incur additional expenses associated with any non-cancelable purchase obligations to our suppliers if they provide customer-specific components.

Adverse Purchase Commitments

We are contractually obligated to reimburse our contract manufacturers for the cost of excess inventory used in the manufacture of our products, for which there is no alternative use. Excess inventory is defined as raw materials or assemblies ("components") used in the manufacture of our products for which the contract manufacturers' on-hand and on-order quantities are in excess of the requirements derived from our current product forecast of customer demand. We are liable for excess inventory only to the extent that the contract manufacturer procures components to fulfill the manufacturing requirements as set forth in our current product forecast and agreed upon lead times and minimum order quantities. Unexpected decreases in customer demand or our inability to accurately forecast customer demand could result in increases in our adverse purchase commitment liability and have a material adverse effect on our profitability. Factors influencing the adverse purchase commitments liability include: changes in demand, rapid technological changes, product life cycle and development plans, component cost trends, product pricing, customer liability and physical deterioration. If actual market conditions are less favorable than those projected by management, we may incur additional expenses due to increases in our adverse purchase commitment liabilities. Our estimate for the adverse purchase commitments liabilities is based on the assumption that our customers comply with their current contractual obligations to us. If our customers experience a financial hardship or if we experience unplanned cancellations of customer contracts, the current adverse purchase commitments liabilities may be inadequate.

Estimates for adverse purchase commitments are derived from reports received on a quarterly basis from our contract manufacturers. Increases to this liability are charged to cost of goods sold. When and if we take possession of inventory reserved for in this liability, the liability is transferred from other liabilities to our excess and obsolete inventory valuation allowance. This liability, referred to as adverse purchase commitments, is provided for in other accrued liabilities in the accompanying balance sheets. Adverse purchase commitments amounted to $2.0 million and $1.9 million at December 31, 2008 and 2007, respectively.

Accrued Warranty

We provide for the estimated cost of product warranties at the time revenue is recognized. Our standard product warranty terms generally include post-sales support and repairs or replacement of a product at no additional charge for a specified period of time, which is generally 24 months after shipment. The workmanship of our products produced by contract manufacturers is covered under warranties provided by the contract manufacturer for a specified period of time ranging from 12 to 15 months. We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Our estimated warranty obligation is based upon ongoing product failure rates, internal repair costs, contract manufacturing repair charges for repairs not covered by the contract manufacturer's warranty, average cost per call and current period product shipments. If actual product failure rates, repair rates, service delivery costs, or post-sales support costs differ from our estimates, revisions to the estimated warranty liability would be required. Additionally, we accrue warranty costs for specific customer product repairs that are in excess of our warranty obligation calculation described above. Accrued warranty reserves are included in other accrued liabilities in the accompanying balance sheets.

Long-Lived Assets

Our long-lived assets include definite-lived intangible assets and property and equipment. The net balance of our definite-lived intangible assets and property and equipment at December 31, 2008 amounted to $19.8 million and $11.6 million, respectively.

In previous years our long-lived asset balance has included goodwill, which represents the excess of cost over the assigned value of the net assets in connection with prior acquisitions. Pursuant to SFAS No. 142, we are required to test goodwill for impairment at least annually. Additionally, we assess goodwill for impairment if any adverse conditions exist that would indicate impairment. Conditions that would trigger an impairment assessment, include, but are not limited to, (i) a significant decline in the Company's market capitalization, (ii) a

significant adverse change in legal factors or in the business climate that could affect the value of an asset, (iii) or an adverse action or assessment by a regulator. The Company is considered one reporting unit. As a result, goodwill impairment testing is performed at the reporting unit level in a two-step process, which consists of, first, comparing the Company's fair value to its carrying value, including goodwill. If the Company's fair value exceeds its carrying value, applicable goodwill is not considered to be impaired. If the Company's carrying value exceeds its fair value, there is an indication of impairment, in which case we would perform the second step, including a further and more detailed analysis in order to corroborate any such impairment.

In accordance with SFAS No. 142, our annual goodwill impairment test was performed during the third quarter of 2008. General economic conditions combined with the resulting decline in the Company's stock price, were considered triggering events that required us to re-perform our goodwill impairment test at the end of the fourth quarter of 2008. To perform the test, a fair value for the Company was estimated primarily based on the market approach, using the market capitalization method. An impairment loss was then calculated based on an allocation of the fair value of the Company to the fair value of the Company's assets and liabilities in a manner similar to a purchase price allocation in a business combination. This resulted in an impairment charge representing the entire balance of goodwill, which totaled $67.3 million, net of adjustments and as of December 31, 2008 we had no remaining indefinite lived intangible assets.

Intangible assets, net of accumulated amortization, primarily consist of acquired patents, completed technology, technology licenses, trade names and customer lists. Intangible assets are being amortized on a straight-line basis over estimated useful lives ranging from one to ten years. Property and equipment, net of accumulated depreciation, primarily consists of office equipment and software, manufacturing equipment, leasehold improvements and other physical assets owned by RadiSys. Property and equipment are being depreciated or amortized on a straight-line basis over estimated useful lives ranging from one to 15 years. We assess impairment of intangible assets and property and equipment whenever conditions indicate that the carrying values of the assets may not be recoverable.

Conditions that would trigger a long-lived asset impairment assessment include, but are not limited to, a significant adverse change in legal factors or in the business climate that could affect the value of an asset or an adverse action or assessment by a regulator. If we determine that a long-lived asset impairment assessment is required, we must determine the fair value of the asset, which is determined based on the associated value of estimated future cash flows. We would estimate future cash flows using assumptions about our expected future operating performance. Our estimates of future cash flows may differ from actual cash flow due to, among other things, technological changes, economic conditions or changes to our business operations. Impairments would be recognized in operating results to the extent that the carrying value exceeds this calculated fair value of the long-lived assets.

Considerable management judgment is required in determining if and when a condition would trigger an impairment assessment of our long-lived assets and once such a determination has been made, considerable management judgment is required to determine the fair market value of the long-lived asset. If the trading price or the average trading price of our common stock is below the book value per share for a sustained period or if and when a condition has triggered an impairment analysis of our long-lived assets, we may incur substantial impairment losses due to the write-down or the write-off of our long-lived assets.

The triggering events that resulted in the impairment analysis of goodwill were also considered triggering events that required us to perform an impairment test of our long lived assets at the end of the fourth quarter of 2008. For our long lived assets, we determined no impairment existed. However, during the analysis we noted that the benefit associated with certain of our intangible assets exceeded their remaining depreciable lives and therefore we adjusted their remaining depreciable lives prospectively. See Note 9 of the Notes to the Consolidated Financial Statements for additional details regarding these changes in accounting estimate.

Income Taxes

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax bases of the assets and liabilities. We record a valuation allowance to reduce deferred tax assets to the amount expected to "more likely than not" be realized in our future tax returns. Should we determine that we would not be able to realize all or part of our net deferred tax assets in the future, adjustments to the valuation allowance for deferred tax assets may be required. The net deferred tax assets amounted to $56.4 million as of December 31, 2008. As of December 31, 2008 we estimate utilization of the net deferred tax assets will require that we generate approximately $56.0 million and $41.5 million in taxable income in the United States and Canada, respectively, prior to the expiration of net operating loss and tax credit carryforwards which will occur between 2009 and 2028. We have considered future market growth, forecasted earnings, future taxable income, the mix of earnings in the jurisdictions in which we operate and prudent and feasible tax planning strategies in determining the need for a valuation allowance. In the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, we would increase the valuation allowance and make a corresponding charge to earnings in the period in which we make such determination. Likewise, if we later determine that we are more likely than not to realize the net deferred tax assets, we would reverse the applicable portion of the previously provided valuation allowance. All future reversals of the valuation allowance would result in a benefit in the period recognized.

Allowance for Doubtful Accounts

We have a relatively small set of multinational customers that typically make up the majority of our accounts receivable balance. Our allowance for doubtful accounts is determined using a combination of factors to ensure that our trade receivables balances are not overstated. We record reserves for individual accounts when we become aware of a customer's inability to meet its financial obligations to us, such as in the case of bankruptcy filings or deterioration in the customer's operating results or financial position. If circumstances related to customers change, our estimates of the recoverability of receivables would be further adjusted. At December 31, 2008, 39.8% of our accounts receivable was due from our two largest customers. If one of these large customers or a number of our smaller customers files for bankruptcy or otherwise is unable to pay the amounts due to us, the current allowance for doubtful accounts may not be adequate. During the years ended December 31, 2008 and 2007, there were no significant account balances reserved for and the allowance for doubtful accounts increased by $86,000 as a result of additional provisions partially offset by the write-off of previously specifically-identified account balances.

We maintain a non-specific bad debt reserve for all customers based on a variety of factors, including the length of time receivables are past due, trends in overall weighted average risk rating of the total portfolio, macroeconomic conditions, significant one-time events and historical experience. Typically, this non-specific bad debt reserve amounts to approximately 1% of quarterly revenues.

Accrued Restructuring and Other Charges

Expenses associated with exit or disposal activities are recognized when probable and estimable. Because we have a history of paying severance benefits, the cost of severance benefits associated with a restructuring charge is recorded when such costs are probable and the amount can be reasonably estimated.

For leased facilities that were vacated and subleased, an amount equal to the total future lease obligations from the date of vacating the premises through the expiration of the lease, net of any future sublease income, was recorded as a part of restructuring charges.

We have engaged, and may continue to engage, in restructuring actions, which require us to make significant estimates in several areas including: realizable values of assets made redundant or obsolete; expenses for severance and other employee separation costs; the ability to generate sublease income, as well as our ability

to terminate lease obligations at the amounts we have estimated; and other exit costs. Should the actual amounts differ from our estimates, the amount of the restructuring charges could be materially impacted. For a description of our restructuring actions, refer to our discussion of restructuring charges in the Results of Operations section.

Revenue Recognition

We recognize revenue when the earnings process is complete, as evidenced by the following revenue recognition criteria: an agreement with the customer; fixed pricing; transfer of title and risk of loss and customer acceptance, if applicable; and that the collectibility of the resulting receivable is reasonably assured. When a sales arrangement contains multiple elements, such as hardware and software products, licenses and/or services, we allocate revenue to each element based on its relative fair value, or for software, based on vendor specific objective evidence ("VSOE") of fair value. In the absence of fair value for a delivered element, we first allocate revenue to the fair value of the undelivered elements and the residual revenue to the delivered elements. Where the fair value for an undelivered element cannot be determined, we defer revenue for the delivered elements until the undelivered elements are delivered. We limit the amount of revenue recognition for delivered elements to the amount that is not contingent on the future delivery of products or services or subject to customer-specified return or refund privileges. We enter into contracts to sell our products and services, and, while the majority of our sales agreements contain standard terms and conditions under which we recognize revenue upon shipment of product, infrequently we enter into agreements that contain non-standard terms and conditions. Non-standard terms and conditions can include, but are not limited to, customer acceptance criteria or other post-delivery obligations. As a result, significant contract interpretation is sometimes required to determine the appropriate timing of revenue recognition. The components of total revenues were as follows (in thousands):

                                             For the Years Ended December 31,
                                             2008            2007         2006
       Hardware                          $    356,228    $    310,001   $ 280,720
       Software royalties and licenses         10,382           9,440       6,193
       Software maintenance                     3,093           2,876       1,402
       Engineering and other services           2,881           2,915       4,166

       Total revenues                    $    372,584    $    325,232   $ 292,481

Hardware

Revenue from hardware products where software is incidental is recognized in accordance with Staff Accounting Bulletin ("SAB") 104. Under our standard terms and conditions of sale, we transfer title and risk of loss to the customer at the time product is shipped to the customer and revenue is recognized accordingly, unless customer acceptance is uncertain or significant obligations remain. We reduce revenue for estimated customer returns for rotation rights as well as for price protection rights according to agreements with our distributors. The amount of revenues derived from these distributors as a percentage of total revenues was 15.2%, 9.9% and 3.4% for the years ended December 31, 2008, 2007 and 2006, respectively.

The software content included in hardware products such as our ATCA systems, certain MCPD products and CMS solutions are considered to be more than incidental and our ATCA arrangements generally include multiple elements such as hardware, technical support services as well as specified software upgrades or enhancements. As such, the revenue associated with these products is recognized in accordance with Statement of Positions ("SOP") 97-2 Software Revenue Recognition ("SOP 97-2").

Software royalties and licenses

Revenue from Software royalties and licenses is recognized in accordance with SOP 97-2. Revenue from customers for prepaid, non-refundable software royalties is recorded when the revenue recognition criteria have been met. Revenue for non-prepaid royalties is recognized at the time the underlying product is shipped by the

customer paying the royalty. We recognize software license revenue at the time of shipment or upon delivery of the software provided all relevant revenue recognition criteria have been met and vendor-specific objective evidence exists to allocate the total fee to all delivered and undelivered elements of the arrangement. We defer revenue on arrangements including specified software upgrades until the specified upgrade has been delivered.

Software maintenance

Software maintenance services are recognized as earned on the straight-line basis over the terms of the contract in accordance with SOP 97-2. The fair value of our post-contract support has been determined by renewal rates within the Company's support agreements as well as the actual amounts charged to customers . . .
