INTRODUCTION

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is intended to assist the reader in better understanding our business, results of operations, financial condition, changes in financial condition, critical accounting policies and estimates, and significant developments. MD&A is provided as a supplement to, and should be read in conjunction with, our unaudited condensed consolidated financial statements and the accompanying notes thereto appearing elsewhere herein. This section is organized as follows:

• Business Overview

• Results of Continuing Operations - an analysis and comparison of our consolidated results of operations for the three and six months ended November 29, 2008, and December 1, 2007, as reflected in our unaudited condensed consolidated statements of operations and comprehensive income (loss).

• Liquidity, Financial Position, and Capital Resources - a discussion of our primary sources and uses of cash for the six months ended November 29, 2008, and December 1, 2007, and a discussion of selected changes in our financial position.

BUSINESS OVERVIEW

Richardson Electronics, Ltd. ("we", "us", and "our") was originally incorporated in the state of Illinois in 1947 and is currently incorporated in the state of Delaware. We are a global provider of engineered solutions and a global distributor of electronic components to the radio frequency ("RF"), wireless and power conversion, electron device, and display systems markets. Utilizing our core engineering and manufacturing capabilities, we are committed to a strategy of providing specialized technical expertise and value-added products, or "engineered solutions," in response to our customers' needs. These solutions include products which we manufacture or modify and products which are manufactured to our specifications by independent manufacturers under our own private labels. Additionally, we provide solutions and add value through design-in support, systems integration, prototype design and manufacturing, testing, and logistics for end products of our customers. Design-in support includes component modifications or the identification of lower-cost product alternatives or complementary products.

Our products include RF and microwave components, power semiconductors, electron tubes, microwave generators, and data display monitors. These products are used to control, switch or amplify electrical power signals, or are used as display devices in a variety of industrial, commercial, and communication applications.

Our sales and marketing, product management, and purchasing functions are organized as follows:

RF, Wireless & Power Division ("RFPD") serves the global RF and wireless communications market, including infrastructure, wireless networks, and the power conversion market.

Electron Device Group ("EDG") provides engineered solutions and distributes electronic components to customers in diverse markets including the steel, automotive, textile, plastics, semiconductor manufacturing, and broadcast industries.

Canvys (formerly the Display Systems Group or "DSG") provides global integrated display products, systems and digital signage solutions serving financial, corporate enterprise, healthcare, and industrial markets.

We currently have operations in the following major geographic regions:

• North America;

• Asia/Pacific;

• Europe; and

• Latin America.

During the second quarter of fiscal 2009, we renamed our DSG business unit to Canvys. This change from DSG to Canvys signifies its evolution to a market-driven solutions group.

During the first quarter of fiscal 2009, we moved our Cathode Ray Tube ("CRT") product line from our Canvys segment to our EDG segment. As a result of implementing a new business plan for Canvys during the third quarter of fiscal 2008, we felt that the CRT product line more closely aligned with the existing EDG business model. Prior period segment information has been restated to reflect this change.

The recent capital and credit market crisis is adversely affecting the U.S. and global economies. Slower economic growth could lead to lower demand for the products we sell. Lower demand for our products could also lead to lower margins on the products that we sell. In addition, our customers may not be able to pay, or may delay payment of accounts receivable that we are owed. Management believes it has taken steps to mitigate this risk through heightened collection efforts.

Net Sales and Gross Profit Analysis

During the second quarter of fiscal 2009, consolidated net sales decreased 8.6% as all three segments experienced a decline compared to prior year. During the first six months of fiscal 2009, consolidated net sales decreased 1.1% due primarily to a decrease in sales of electron device and Canvys products, partially offset by an increase in wireless and power conversion products.

Net sales by segment and percent change during the second quarter and first six months of fiscal 2009 and 2008 were as follows (in thousands):

                  Net Sales         FY 2009       FY 2008    % Change

                  Total            $ 271,498     $ 274,450       (1.1 )%

Consolidated gross profit decreased slightly during both the second quarter and first six months of fiscal 2009 as compared to the second quarter and first six months of fiscal 2008. Consolidated gross margin as a percentage of net sales increased to 25.0% and 24.3% during the second quarter and first six months of fiscal 2009, respectively, as compared to 23.3% and 24.2% during the second quarter and first six months of fiscal 2008, respectively, due primarily to increased focus on higher margin products.

Gross profit reflects the distribution and manufacturing product margin less manufacturing variances, inventory obsolescence charges, customer returns, scrap and cycle count adjustments, engineering costs, and other provisions. Corporate gross profit includes certain freight costs and other miscellaneous charges.

Gross profit by segment and percent of segment sales during the second quarter and first six months of fiscal 2009 and 2008 were as follows (in thousands):

RF, Wireless & Power Division

RFPD net sales were $93.4 million during the second quarter of fiscal 2009, a $2.1 million decrease, or 2.1%, from $95.5 million during the second quarter of fiscal 2008. The decrease in net sales during the second quarter was due primarily to a decline in sales of network access products, partially offset by an increase in sales of infrastructure and power conversion products. Net sales increased during the first six months of fiscal 2009 to $190.3 million, a $10.5 million increase, or 5.9%, from $179.8 million during the first six months of fiscal 2008. The increase in net sales during the first six months was due primarily to an increase in sales of infrastructure and power conversion products, partially offset by a decrease in net sales of network access products. Network access sales decreased 12.2% and 0.9% to $33.2 million and $69.4 million during the second quarter and first six months of fiscal 2009, respectively, from $37.8 million and $70.0 million during the second quarter and first six months of fiscal 2008, respectively. The decline in net sales of network access products was primarily in North America, Asia/Pacific, and Europe. Net sales of network access declined due to lower capital investment of network applications which was primarily the result of the weakening global economy. Infrastructure net sales increased 7.9% and 13.5% to $25.9 million and $52.1 million in the second quarter and first six months of fiscal 2009, respectively, from $24.0 million and $45.9 million during the second quarter and first six months of fiscal 2008, respectively. The net sales growth for infrastructure products was primarily in Asia/Pacific, which was due primarily to the deployment of the next infrastructure build-out of the Time Division-Synchronous Code Division Multiple Access ("TD-SCDMA") project in China. Phase two of TD-SCDMA project was deployed during the first quarter of fiscal 2009 which is expected to be completed by the end of fiscal 2009, while phase one of the project occurred during fiscal 2007. Additionally, infrastructure increased due to the global investment in wideband code division multiple access ("W-CDMA") applications during the second quarter of fiscal 2009. Power conversion net sales increased 11.5% and 15.0% to $15.5 million and $30.6 million during the second quarter and first six months of fiscal 2009, respectively, from $13.9 million and $26.6 million during the second quarter and first six months of fiscal 2008, respectively, as all four geographic regions experienced growth. Net sales of power conversion products in Asia/Pacific benefited from RFPD's penetration of the welding and steel manufacturing market with induction heating and power supply applications, as well as the growth in the application of alternative energy. Gross margin as a percent of net sales slightly increased to 22.8% during the second quarter of fiscal 2009 from 22.1% during the second quarter of fiscal 2008 due to shifts in product mix. Gross margin as a percent of net sales decreased to 22.2% during the first six months of fiscal 2009 from 23.1% during the first six months of fiscal 2008. The decline in gross margin as a percent of net sales was due primarily to the lower margins generated from the TD-SCDMA project in China.

Electron Device Group

EDG net sales were $22.2 million during the second quarter of fiscal 2009, a $6.6 million decrease, or 22.8%, from $28.8 million during the second quarter of fiscal 2008. Net sales decreased during the first six months of fiscal 2009 to $47.3 million, a $7.6 million decrease, or 13.8%, from $54.9 million during the first six months of fiscal 2008. The net sales decline for both periods was due primarily to a decline in semiconductor fabrication equipment products and tube sales. Net sales of semiconductor fabrication equipment declined 28.8% and 23.6% to $3.7 million and $8.1 million during the second quarter and first six months of fiscal 2009, respectively, from $5.2 million and $10.6 million during the second quarter and first six months of fiscal 2008. The semiconductor fabrication equipment industry has experienced an overall decline during the past couple of years. Net sales of tubes decreased 19.6% and 11.5% to $15.6 million and $32.4 million during the second quarter and first six months of fiscal 2009, respectively, from $19.4 million and $36.6 million during the second quarter and first six months of fiscal 2008. Net sales of tubes decreased primarily in North America and Europe. The decline in North America, during both the second quarter and first six months of fiscal 2009, was due primarily to the conversion from analog to digital television in the U.S which takes place in February 2009. Gross margin as a percent of net sales increased to 35.2% and 32.7% during the second quarter and first six months of fiscal 2009, respectively, as compared to 32.3% during both the second quarter and first six months of fiscal 2008. The increase in gross margin for EDG was due primarily to a shift in product mix toward higher-margin products.

Canvys

Canvys net sales were $16.8 million during the second quarter of fiscal 2009, a $2.7 million decrease, or 13.7%, from $19.5 million during the second quarter of fiscal 2008. Net sales decreased during the first six months of fiscal 2009 to $33.9 million, a $3.4 million decrease, or 9.2%, from $37.4 million during the first six months of fiscal 2008. The net sales decline for both periods was due primarily to a decline in medical imaging products, partially offset by an increase in digital signage products. During the third quarter of fiscal 2008, Canvys implemented a new business plan, part of which included exiting unprofitable market segments and the distribution of low margin branded products. Due to a focus on profitable sales growth, gross margin improved to 24.7% and 25.0% during the second quarter and first six months of fiscal 2009, respectively, from 20.0% and 20.6% during the second quarter and first six months of fiscal 2008, respectively, which we believe will be a sustainable long-term improvement.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses ("SG&A") decreased during the second quarter and first six months of fiscal 2009 to $28.2 million and $56.4 million, respectively, from $31.3 million and $61.3 million during the second quarter and first six months of fiscal 2008, respectively. The decrease in SG&A expense during the second quarter and first six months of fiscal 2009 was due primarily to a decline in consulting, employee-related, travel, and facility expenses. SG&A as a percent of net sales declined to 21.3% and 20.8% of net sales during the second quarter and first six months of fiscal 2009, respectively, as compared with 21.6% and 22.3% of net sales during the second quarter and first six months of fiscal 2008, respectively.

Other (Income) Expense

Other (income) expense was $1.4 million and $1.5 million of income during the second quarter and first six months of fiscal 2009, respectively, as compared to an expense of $2.7 million and $5.4 million during the second quarter and first six months of fiscal 2008, respectively. The change to income from expense was due primarily to favorable changes in foreign currency exchange rates, a gain related to the retirement of a portion of our long-term debt, and a decrease in interest expense. Other (income) expense included a foreign exchange gain of $1.5 million and $2.5 million during the second quarter and first six months of fiscal 2009, respectively, as compared to a foreign exchange loss of $1.4 million and $1.8 million during the second quarter and first six months of fiscal 2008, respectively. The second quarter and first six months of fiscal 2009 included a gain of $0.8 million related to the retirement of $3.3 million of our 8% notes. See Note 7 "Debt" of our unaudited condensed consolidated financial statements for additional discussion on the retirement. Interest expense decreased to $1.2 million and $2.4 million during the second quarter and first six months of fiscal 2009, respectively, as compared to $1.6 million and $4.2 million during the second quarter and first six months of fiscal 2008, respectively. See Note 7 "Debt" of our unaudited condensed consolidated financial statements for additional discussion on interest expense.

Income Tax Provision

The effective income tax rate for the second quarter and first six months of fiscal 2009 was a provision of 6.7% and 11.9%, respectively, as compared with a provision of 214.8% and 265.5% for the second quarter and first six months of fiscal 2008, respectively. The difference between the effective tax rates as compared to the U.S. federal statutory rate of 34% primarily results from our geographical distribution of taxable income or losses and valuation allowances related to net operating losses. For the first six months of fiscal 2009, we realized a tax benefit from the partial release of the valuation allowances related to net operating losses of $0.9 million. The tax provision for the first six months of fiscal 2009 includes $0.6 million related to prior years income tax of one of our foreign jurisdictions.

In the normal course of business, we are subject to examination by taxing authorities throughout the world. We are no longer subject to either U.S. federal, state, or local tax examinations by tax authorities for years prior to fiscal year 2004. With few exceptions, we are no longer subject to non-U.S. income tax examinations by tax authorities for years prior to fiscal year 2002. Our

primary foreign tax jurisdictions are the United Kingdom, Germany, Singapore, and the Netherlands. We have tax years open in Singapore beginning in fiscal year 2002; in Germany and the Netherlands beginning in fiscal year 2003; in the U.S. beginning in fiscal year 2004; and in the United Kingdom beginning in fiscal year 2006.

As of November 29, 2008, our worldwide liability for uncertain tax positions, excluding interest and penalties, is $4.7 million as compared to $6.0 million as of May 31, 2008. We record penalties and interest relating to uncertain tax positions in the income tax expense line item within the unaudited condensed consolidated statements of operations and comprehensive income (loss). The net liability for uncertain tax positions decreased in the three months ended November 29, 2008, primarily due to closure of certain statutes of limitation.

It is reasonably possible that there will be a change in the unrecognized tax benefits in the range of $0 to approximately $1.2 million due to the expiration of various statutes of limitations within the next 12 months.

Net Income (Loss) and Per Share Data

Net income during the second quarter of fiscal 2009 was $5.9 million, or $0.31 per diluted common share and $0.28 per Class B diluted common share as compared with a net loss of $0.7 million during the second quarter of fiscal 2008, or $0.04 per diluted common share and $0.03 per Class B diluted common share. Net income during the first six months of fiscal 2009 was $9.6 million, or $0.52 per diluted common share and $0.47 per Class B diluted common share as compared with a net loss of $1.0 million during the first six months of fiscal 2008, or $0.06 per diluted common share and $0.05 per Class B diluted common share.

LIQUIDITY, FINANCIAL POSITION, AND CAPITAL RESOURCES

We have financed our growth and cash needs largely through income from operations, borrowings under the revolving credit facilities, issuance of convertible senior subordinated notes, and sale of assets. Liquidity is reduced by working capital requirements, debt service, capital expenditures, dividends, and business acquisitions. Liquidity is increased by proceeds from borrowings, disposition of businesses and assets, and improved working capital management.

Cash and cash equivalents were $35.5 million as of November 29, 2008, as compared to $40.0 million as of May 31, 2008.

Cash Flows from Operating Activities

Cash provided operating activities during the first six months of fiscal 2009 was $3.6 million, due primarily to higher accounts payable balances and lower accounts receivable balances, partially offset by higher inventory balances and lower accrued liability balances. The increase in accounts payable balances of $5.4 million, excluding the impact of foreign currency exchange of $1.9 million, during the first six months of fiscal 2009 was due primarily to negotiating favorable payment terms with many of our vendors. The decline in accounts receivable balances of $2.1 million, excluding the impact of foreign currency of $7.3 million, during the first six months of fiscal 2009 was due primarily to a decline in sales volume. The increase in inventory balances of $10.4 million, excluding the impact of foreign currency exchange of $4.6 million, during the first six months of fiscal 2009 was due primarily to purchases of inventory necessary to support anticipated sales volume in future quarters. The decline in accrued liability balances of $2.2 million, excluding the impact of foreign currency exchange of $0.8 million, during the first six months of fiscal 2009 was due primarily to the timing and payment of accrued payroll and accrued taxes.

Cash provided by operating activities during the first six months of fiscal 2008 was $8.7 million, primarily due to lower accounts receivable and higher accounts payable balances, partially offset by higher inventory balances. Accounts receivable declined

$5.4 million, excluding the impact of foreign currency exchange of $4.1 million, during the first six months of fiscal 2008 was due primarily to improved cash collections. Accounts payable balances increased $11.7 million, excluding the impact of foreign currency exchange of $1.1 million, during the first six months of fiscal 2008 was due primarily to negotiating with many of our vendors related to payment terms. Inventory balances increased $1.4 million during the first six months of fiscal 2008, excluding the impact of foreign currency exchange of $4.1 million.

Cash Flows from Investing Activities

Net cash used by investing activities was $0.6 million during the first six months of fiscal 2009, primarily due to capital expenditures of $0.5 million and contingent purchase price payments of $0.1 million.

Net cash used by investing activities was $3.5 million during the first six months of fiscal 2008, primarily due to capital expenditures for information . . .
