RICHARDSON ELECTRONICS REPORTS FIRST QUARTER

FISCAL 2010 RESULTS AND DECLARES CASH DIVIDEND

LaFox, IL, October 7, 2009: Richardson Electronics, Ltd. (NASDAQ: RELL) today reported net sales during the first quarter ended August 29, 2009, of $109.5 million, a 21.2% decrease from net sales of $138.9 million during the first quarter of last year. Net income during the first quarter was $1.9 million, or $0.11 per diluted common share, as compared with net income of $3.7 million, or $0.20 per diluted common share, during the first quarter of last year.

Operating income during the first quarter was $3.5 million as compared with operating income of $4.5 million during last year’s first quarter. Selling, General, and Administrative (“SG&A”) expenses were $22.9 million, down $5.3 million or 18.8%, compared to SG&A expenses of $28.2 million during the first quarter of last year.

“Although sales were well below last year’s first quarter, we were pleased that our operating margin remained at 3.2%. This reflects both gross margin improvement as well as our continued cost reductions. These actions should lead to significantly improved operating leverage as sales begin to recover,” said Edward J. Richardson, Chairman, Chief Executive Officer and President of Richardson Electronics, Ltd.

FOCUS ON WORKING CAPITAL MANAGEMENT AND CASH FLOWS

Cash flows used in operating activities were $2.2 million during the first quarter of fiscal 2010, compared to $1.0 million used during last year’s first quarter. Our debt less cash at the end of our first quarter of fiscal 2010 was $10.6 million, an $8.0 million improvement, compared to $18.6 million at the end of the prior year’s first quarter.

“Although we invested $3.7 million of cash during the first quarter in working capital, we did so cautiously in order to be in a position to support our customers as global market conditions improve. We remain committed to improving our working capital management and expect our operations to generate positive cash flows for the remainder of fiscal 2010,” said Kathleen S. Dvorak, Executive Vice President and Chief Financial Officer.

During the first quarter, the Company did not repurchase any shares of its common stock under its share repurchase program. The share repurchase program was approved by the Company’s Board of Directors in January 2009. The share repurchase program does not have an expiration date and may be exercised at any time.

OUTLOOK

“In the near term, our sales volume will continue to be impacted by the weak global economic conditions, and as a result, we anticipate that sales for the second quarter of fiscal 2010 will be down in the range of 10% to 15% compared to the prior year. Our cost reduction efforts, combined with increased efficiencies, should position the company for improved profitability. We are now on track to spend less than $95 million for SG&A during fiscal 2010,” 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 November 20, 2009, to all common stockholders of record on November 6, 2009. The Company currently has 14,866,774 outstanding shares of common stock and 3,048,258 outstanding shares of Class B common stock.
