Fiscal December Revenue Summary
(U.S. dollars in billions)

1 International segment revenue change includes a favorable foreign currency exchange rate impact. Consistent with prior presentations, results of operations in all countries in the international segment other than Canada are reported on a two-month lag.

2 Our comparable store sales is comprised of revenue from stores operating for at least 14 full months as well as revenue related to call centers, Web sites and our other comparable sales channels.  Revenue we earn from sales of merchandise to wholesalers or dealers is not included within our comparable store sales calculation. Relocated, remodeled and expanded stores are excluded from the comparable store sales calculation until at least 14 full months after reopening. Acquired stores are included in the comparable store sales calculation beginning with the first full quarter following the first anniversary of the date of the acquisition. The portion of our calculation of the comparable store sales percentage change attributable to our International segment excludes the effect of fluctuations in foreign currency exchange rates. The method of calculating comparable store sales varies across the retail industry. As a result, our method of calculating comparable store sales may not be the same as other retailers’ methods.

LAS VEGAS, Jan. 7, 2011 — Best Buy Co., Inc. (NYSE: BBY) today reported from the Consumer Electronics Show that revenue for the fiscal month of December ended Jan. 1, 2011, decreased 1.6 percent to $8.4 billion. The revenue decline for the five-week period, as compared to $8.5 billion in revenue for the five-week period ended Jan. 2, 2010, was due primarily to a comparable store sales decline of 4.0 percent partially offset by the addition of new stores in the past 12 months and the favorable impact of fluctuations in foreign currency exchange rates.

“December sales results were within our expected range of outcomes for the month, and I’d like to thank our employees for making a difference in providing outstanding customer experiences this holiday season,” said Brian Dunn, CEO of Best Buy.

Strength in Best Buy Mobile Partially Offsets Continued Consumer Softness in Televisions

The company’s Domestic segment generated $6.5 billion in revenue for fiscal December, a decrease of 3.2 percent when compared with the same period last year. The Domestic segment’s revenue performance included a comparable store sales decline of 5.0 percent and gains from new stores in the past 12 months.

In the Domestic segment, the entertainment software category comparable store sales declined 15.4 percent driven primarily by a decrease in gaming and continued softness in music and movies. The consumer electronics category posted a 7.9 percent comparable store sales decrease due primarily to a low double-digit decline in televisions as the industry continued to experience softness, partially offset by strength in e-readers. The home office category experienced a 4.3 percent comparable store sales increase as a result of a low double-digit increase in mobile phones, driven primarily by an increase in the mix of smart phones. A mid single-digit comparable store sales increase in mobile computing further contributed to the growth in the category driven by strength in tablet computers. The appliances category experienced a 10.9 percent comparable store sales increase and the services category recorded a 7.6 percent comparable store sales increase. The company noted that Domestic online revenue in fiscal December increased 13 percent versus the prior-year period.

The International segment’s fiscal December revenue totaled $1.9 billion, an increase of 4.5 percent versus the prior-year period. The revenue gain was driven primarily by favorable fluctuations in foreign currency exchange rates and the addition of new stores in the past 12 months, partially offset by a comparable store sales decline of 0.1 percent in fiscal December. Similar to trends in the Domestic segment, Canada reported a low single-digit comparable store sales decline. Best Buy Europe reported a mid single-digit comparable store sales gain due to demand for smart phones and strong online performance. China reported a mid single-digit comparable store sales gain driven by

strong year-over-year performance during the Golden Week holiday.  As a reminder, the company’s Europe and China operations are reported on a two-month lag and therefore reflect October results.
