Company to Delay By Two Days Its Release of Fourth-Quarter Earnings in Order to Incorporate Recent Resolution of Tax Matters

Best Buy’s Favorable Resolution of Tax Matters to Increase FY’05 Earnings by at Least $50 Million

MINNEAPOLIS, March 29, 2005 — Best Buy Co., Inc. (NYSE: BBY), North America’s leading retailer of consumer electronics, today reported that it plans to delay the reporting of its fourth-quarter earnings until the morning of Friday, April 1, 2005, in order to ensure that the company properly reflects the recent, favorable resolution of tax matters related to its former Musicland subsidiary and other tax matters.

The company reported that its results from discontinued operations for the fiscal fourth quarter, which ended on Feb. 26, 2005, will include a $50 million tax benefit related to Musicland. This benefit, amounting to 15 cents per diluted share, resulted from the favorable, final resolution on March 25, 2005, of outstanding tax matters with the Internal Revenue Service. The tax benefit, which will be included in discontinued operations, was not included in the company’s previous earnings guidance.

Included in the company’s fourth-quarter earnings will be not only the Musicland-related tax benefit, but also the favorable impact of resolving, late in the fourth quarter, other state and federal tax matters, as well as the unfavorable impact of an accounting adjustment made as a result of the company’s review of its leases. Both of the latter two items will be included in earnings from continuing operations.

The company also has rescheduled its earnings conference call for 10 a.m. EST on April 1, 2005. The call is expected to be available on Best Buy’s Web site both live and after the call, at www.BestBuy.com. The public may access the call by clicking on “For Our Investors.”  Both the conference call and the earnings release originally were scheduled for Wednesday, March 30.
