RICHARDSON ELECTRONICS REPORTS SECOND QUARTER

FISCAL 2010 RESULTS AND DECLARES CASH DIVIDEND

LaFox, IL, January 6, 2010: Richardson Electronics, Ltd. (NASDAQ: RELL) today reported net sales for the second quarter ended November 28, 2009, of $115.9 million, a 12.5% decrease from net sales of $132.6 million for the second quarter of last year. Operating income during the second quarter was $5.4 million, or 4.6% of net sales, as compared with operating income of $5.0 million, or 3.7% of net sales, during last year’s second quarter. Income from continuing operations during the second quarter was $4.3 million, or $0.24 per diluted common share, as compared with income from continuing operations of $5.9 million, or $0.31 per diluted common share, during the second quarter of last year.

Loss from discontinued operations for the second quarter of fiscal 2010 of $1.2 million represents a final settlement of working capital based purchase price adjustment claims and other related claims from the divestiture of the Security Systems Division in May of 2007.

“We were very pleased with the Richardson team’s execution during the second quarter as our revenue, working capital management, and cash flows were in line with our expectations. While our year-over-year revenue decline reflects the uncertain global economy, our strengthening sales trends provide confidence that our business environment is improving. We continue to find cost savings throughout our company which we believe will provide further opportunities for operating margin improvement,” said Edward J. Richardson, Chairman, Chief Executive Officer and President of Richardson Electronics, Ltd.

CASH FLOW, WORKING CAPITAL MANAGEMENT, DEBT REDUCTION

Cash flows provided by operating activities were $6.9 million during the second quarter of fiscal 2010, compared to $4.5 million during the second quarter of last year. Our debt less cash at the end of our second quarter was $2.4 million compared to $16.9 million at the end of the second quarter last year.

“We generated $1.9 million of cash from our working capital investments during the second quarter compared to using $0.3 million of cash during last year’s second quarter. We expect our operations to generate positive cash flows for the remainder of the year and plan to take advantage of opportunities to reduce both our long-term debt and interest expense,” said Kathleen S. Dvorak, Executive Vice President and Chief Financial Officer.

On December 11, 2009, the Company provided notice to the holders of its 8% convertible senior subordinated notes that it was redeeming all $7.7 million in aggregate principal outstanding at face value on January 11, 2010. In addition, the Company purchased $0.9 million of its 7 ³/4% convertible senior subordinated notes at 97% of face value during December 2009. As a result of these transactions, the Company’s long-term debt will be reduced by approximately $8.5 million during the third quarter of fiscal 2010.

2

During January 2010, the Company will be repurchasing approximately 300,000 shares of its common stock held in its Employee Stock Ownership Plan (“ESOP”) in a private transaction. The ESOP was terminated on October 15, 2009.

OUTLOOK

“While the economic environment is still uncertain, we are encouraged by our current level of backlog and believe that our sales for the third quarter will be in the range of $115 million to $120 million which is positive sales growth compared to sales of $110 million during last year’s third quarter. Our cost reduction efforts are clearly reflected in the 4.6% operating margin achieved in the second quarter. Our goal is to deliver further improvements in operating margin for the balance of the year,” concluded Mr. Richardson.

CASH DIVIDEND

The Company today also announced that its Board of Directors voted to declare a $0.02 cash dividend per share to all holders of common stock and a $0.018 cash dividend per share to all holders of Class B common stock. The dividend will be payable on February 19, 2010, to all common stockholders of record on February 10, 2010. The Company currently has 14,867,811 outstanding shares of common stock and 3,048,258 outstanding shares of Class B common stock.
