MINNEAPOLIS, Aug. 7, 2003 — Best Buy Co., Inc. (NYSE: BBY) today raised its estimate for second-quarter diluted earnings per share from continuing operations to a new range of 37 to 42 cents, compared with analysts’ consensus of 30 cents per share. The Company’s prior guidance, which was originally provided on June 18, was a range of 27 to 32 cents per share for the quarter which ends on Aug. 30, 2003.

The Company reported earnings from continuing operations of $79 million, or 24 cents per diluted share, for last year’s second quarter, which ended on Aug. 31, 2002.

“Strong comparable store sales growth, increasing gross profit rates and diligent cost controls all are contributing to the higher earnings guidance from continuing operations for the second quarter and for the fiscal year,” said Darren Jackson, executive vice president and chief financial officer.

“Our employees are driving this excellent performance through a number of initiatives to limit gross profit drains from markdowns, product returns and exchanges while delivering on cost-savings programs. In addition, consumers continue to migrate to higher-margin products, such as digital TVs,” Jackson added. “The gross profit rate from continuing operations is the largest contributor to the improved outlook. The gross profit rate is expected to increase by at least 70 basis points for the current period, compared with 24.9 percent of revenue in the second quarter of fiscal 2003.”

The Company’s prior earnings guidance had contemplated no change in the gross profit rate for the second quarter. Jackson noted that the Company’s selling, general and administrative expense rate is improving, and comparable store sales are still on pace to grow by the mid-single digits for the quarter.

The CFO added, “We had not expected our financial performance to improve significantly until the second half of the fiscal year, and are pleased that we are seeing it pick up earlier. We continue to believe that we will achieve our internal projections for the second half of the fiscal year. As usual, we plan to provide investors with our initial earnings guidance for the third and fourth quarters during our second-quarter conference call. Given the better-than-expected operating results we are now anticipating for the second quarter, we are forecasting diluted earnings per share from continuing operations of $2.27 to $2.32 for the fiscal year, compared to analysts’ consensus of $2.22 per diluted share. Our prior guidance was $2.17 to $2.22 per diluted share, and we reported diluted earnings per share from continuing operations of $1.91 for fiscal 2003.”

As previously reported, the Company sold its interest in The Musicland Group, Inc. earlier this quarter and has classified the former subsidiary’s results as discontinued operations. Final adjustments related to the sale, if any, are expected to be included in second-quarter results.

The Company is expected to announce its second-quarter sales on Sept. 4, 2003, and its second-quarter earnings on Sept. 17, 2003.
