Item 7.01 Regulation FD Disclosure.

As previously disclosed, on October 1, 2010, Richardson Electronics, Ltd., a Delaware corporation (the “Company”), certain subsidiaries of the Company (collectively with the Company, the “Sellers”), and Arrow Electronics, Inc., a New York corporation (“Arrow”) entered into an Acquisition Agreement (the “Acquisition Agreement”). The Acquisition Agreement provides that Arrow will acquire all of the assets primarily used or held for use in, and certain liabilities of, the Company’s RF, Wireless & Power Division (“RFPD”), as well as certain other Company assets, including its information technology assets, in exchange for $210 million in cash payable at closing, subject to a post-closing working capital adjustment (the “Transaction”).

As previously announced, the Company’s 2010 annual meeting of stockholders will be held on Tuesday, October 5, 2010 at 3:15 P.M. CT at the corporate headquarters in LaFox, Illinois. At the meeting, stockholders will vote on the directors standing for election and to ratify the selection of Ernst & Young LLP as the independent registered public accounting firm for fiscal 2011.

Also as previously announced, on Thursday, October 7th, 2010, at 9:00 a.m. CT, Edward J. Richardson, Chairman and Chief Executive Officer, and Kathleen S. Dvorak, Chief Financial Officer, will host a conference call to discuss the Company’s first quarter fiscal 2011 results. A question and answer session will be included as part of the call’s agenda.

The Transaction will not be acted upon at the annual meeting of stockholders and will not be a subject of the conference call; however the Company anticipates that it may be asked questions at the annual meeting and during the conference call regarding the amount and use of the after-tax proceeds of the Transaction.

The Company estimates that its after-tax proceeds from the Transaction will be approximately $180 - $185 million. The Company has not yet determined how it will use the proceeds, but it may use them for a variety of purposes, including any or all of the following: strategic acquisitions, repurchases of outstanding shares of common stock, dividends to stockholders and general corporate purposes.

Among the strategic acquisitions that the Company is considering are acquisitions of companies involved in engineering and manufacturing components, including components used in alternative energy markets. However, the Company has not yet made any decisions regarding any acquisitions or any other use of the proceeds of the Transaction.

The Company is developing a plan to align its cost structure for its remaining businesses after the closing of the Transaction with the goal of maintaining their current level of profitability.

This Form 8-K is being furnished solely to satisfy the requirements of Regulation FD. The Company does not intend to update this information or release similar information in the future. The furnishing of the information under Item 7.01 in this Current Report on Form 8-K is not intended to, and does not, constitute a determination or admission by the Company that the information under Item 7.01 in this Current Report on Form 8-K is material or complete, or that investors should consider this information before making an investment decision with respect to any security of the Company.
