         of management, all adjustments necessary for a fair presentation of
         such financial statements have been included and were normal and
         recurring in nature. The Company's business is seasonal in nature and
         interim results are not necessarily indicative of results for a full
         year. These interim financial statements and the related notes should
         be read in conjunction with the financial statements and notes included
         in the Company's Annual Report to Shareholders for the fiscal year
         ended February 27, 1999, and incorporated by reference into the
         Company's Annual Report on Form 10-K. Certain prior year amounts have
         been reclassified to conform to current year presentation.

2.       INCOME TAXES:

         Income taxes are provided on an interim basis based upon management's
         estimate of the annual effective tax rate. Management's revised
         estimate of the annual effective tax rate of 38.3% for fiscal 2000
         reflects higher levels of tax exempt interest income. This revised
         annual estimate resulted in an effective rate of 38.1% for the
         second quarter.

4.       CREDIT FACILITY:

         In August 1999, the Company entered into an unsecured $100 million
         revolving credit facility, replacing the $220 million facility that was
         scheduled to mature in June 2000. The Company was able to reduce the
         size of the facility due to improved operating performance and better
         inventory management. In addition, the new facility makes certain
         financial covenants less restrictive thereby providing the Company with
         additional flexibility. The current facility is scheduled to mature in
         August 2002.

5.       SHARE REPURCHASE PROGRAMS:

         In October 1998, the Company's Board of Directors approved the purchase
         of up to $100 million of the Company's common stock from time to time
         through open market purchases over the following twelve months. As of
         August 28, 1999, this repurchase program was completed with a total of
         1.8 million shares purchased.

         In September 1999, the Company's Board of Directors approved the
         purchase of up to $200 million of the Company's common stock from time
         to time through open market purchases. This repurchase program has no
         stated expiration date.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Net earnings for the second quarter of fiscal 2000 were a record $59.0 million,
or $.28 per share on a diluted basis, compared to net earnings of $44.1 million,
or $.21 per share, for the comparable period last year. For the first six months
of the current fiscal year net earnings were a record $106.3 million, or $.50
per share on a diluted basis, compared to $59.9 million, or $.29 per share, for
the same period last year. Continued strength in consumer spending and market
share gains combined with continued improvement in gross profit margins were the
principal factors generating the record results. Pre-opening expenses incurred
in connection with the opening of 19 new stores during the quarter reduced net
earnings for the second quarter of the current year by approximately $8 million,
or $.04 per diluted share. No new stores were opened in the second quarter of
fiscal 1999.

Revenues in the second quarter increased 23% to $2.688 billion compared to
$2.182 billion in the second quarter last year. Revenues in the first six months
increased 23% to $5.074 billion compared to $4.126 billion last year. Comparable
store sales increases of 11.1% for the second quarter and 12.2% year-to-date and
a net increase of 43 new stores in the past twelve months drove the revenue
increases. The Company's multi-year program to offer a more customer focused
product assortment, improve in-stock levels and increase advertising
effectiveness, coupled with successful retail execution, has allowed the Company
to capitalize on the continued strength in the overall retail sector and
generate comparable store sales increases in excess of 10% for seven consecutive
quarters. Sales of digital technology products such as Digital Versatile Disc
(DVD), Digital Broadcast Satellite (DBS), digital cameras and camcorders, as
well as strong sales of personal computers and music and movies, fueled the
comparable store sales gains. All major product categories generated comparable
store sales increases as the Company continued to gain market share.

As of August 28, 1999, the Company operated 332 stores compared to 289 stores
one year ago. In the second quarter, the Company opened 19 new stores,
including five new stores in the San Francisco market and the first three of
the Company's new small market stores designed to serve markets with
populations less than 200,000. The Company also expanded four stores and
relocated three stores to larger facilities. The new stores and store
expansions were Concept IV stores which feature improved merchandising,
signage and customer service and are expected to better address customers'
needs as the industry continues to progress into new digital products. The
Company plans to open 23 new stores in the third quarter including entry into
the new markets of San Diego, California; Jacksonville and Tallahassee,
Florida; Richmond and Norfolk, Virginia; Rochester and Albany, New York; and
Providence, Rhode Island. In addition, the Company announced plans to open 55
to 60 new stores in fiscal 2001, including entry into the New York
metropolitan market with approximately twelve stores.

The Company is investing in building the systems infrastructure, vendor
relationships and content base to support its developing e-commerce business,
BestBuy.com. The Company is in the process of recruiting several new executives
to fill critical leadership roles in developing its online presence. The Company
anticipates introducing expanded product offerings on its website in early
calendar 2000. Internet operations are not expected to contribute materially to
the Company's total revenues in the current fiscal year.

In the home office category, the launch of an Internet Service Provider (ISP)
subsidy offer on personal computers in the second quarter represented a
significant change in the retailing of personal computers. The ISP subsidy offer
quickly became common practice among retailers. The offer provides customers
with an instant rebate on the purchase of a personal computer when the customer
signs an extended contract to subscribe to Internet service provided by the ISP.
This rebate to the customer is funded by the ISP which also bears the risk of
collection of the monthly subscriber fees paid by the customer to the ISP. The
Company believes it has had a distinct advantage by being able to provide the
rebate to the customer at the time of the sale as opposed to utilizing a mail-in
rebate used by most other retailers. This program has been successful in driving
significant increases in unit volumes of personal computers, particularly the
lower price point, entry-level models. The higher volumes have been sufficient
to offset the decline in average selling price of computers sold by the Company
and resulted in a double-digit comparable store sales increase in the home
office category. The increased unit volumes also resulted in higher sales of
accessories and performance service plans (PSPs) that accompany the sale of
personal computer hardware.

Sales of digital technology products such as DVD, digital camcorders and DBS,
as well as strong sales of analog products such as televisions and home
theater systems, drove second quarter and year-to-date sales increases in the
consumer electronics category. The Company remains the industry leader in DVD
hardware sales market share and continues to effectively capitalize on the
consumer demand for digital products.

Sales of entertainment software, which includes music and movies, computer
software and video games, increased moderately in the second quarter. Sales
of compact discs and DVD movies were particularly strong despite a lack of
significant new releases. DVD movies outsold VHS movies for the first time in
the second quarter due to consumers' rapid acceptance of the DVD format. The
Company leads the industry in DVD software sales market share and, by
year-end, expects to offer over 2,000 DVD movie titles aided by the expected
release of Disney classic cartoon titles beginning in October. Strong sales
of music and movies were offset by softer sales of computer software and
video games due to declining average selling prices, a lack of new software
titles and the anticipated transition to advanced technology game systems in
the third quarter.

Management expects that comparable store sales increases could moderate in
the future as comparisons become more difficult. Additionally, the Company's
revenues are dependent upon adequate quantities of products from the
Company's suppliers. While management does not currently expect product
shortages, events such as natural disasters, component part availability, or
supply issues resulting from year 2000 systems issues could impact the
availability of product from the Company's suppliers and impact revenues.

Gross profit margin in the second quarter improved to 19.8% compared to 18.8% in
the second quarter of fiscal 1999, a full 1% of sales improvement. Gross profit
margin in the six-month period improved 1.1% of sales to 19.6% compared to 18.5%
in the same period last year. These improvements reflect the continuing benefit
from the Company's initiatives to generate more profitable product assortments,
improve inventory management and enhance advertising effectiveness. Increased
sales of higher margin PSPs and accessories favorably impacted margins in the
quarter and year-to-date periods. Sales of PSPs accounted for 4.2% of total
sales for both the second quarter and six-month period of the current year
compared to 3.9% and 3.8% for the quarter and six-

                                       11


month period of the prior year, respectively. The Company's ongoing efforts
to reduce inventory shrink also contributed to the margin improvements.
Management expects gross profit margins will continue to exceed prior year
levels in the second half of this year. However, an expected seasonal change
will result in a lower gross profit margin in the second half of the year as
compared to the first half. This change is due, in part, to a seasonal
product sales mix shift, which typically includes more personal computers and
fewer appliances and mobile electronics. In addition, promotional activity
typically increases during the holiday season and during store grand opening
events. The percentage of higher margin PSP sales in the mix declines during
the holiday season, also impacting gross profit margins in the second half of
the year.

Selling, general and administrative (SG&A) expenses increased to 16.4% of sales
in the quarter compared to 15.5% in the second quarter last year. Year-to-date,
SG&A expenses increased to 16.4% of sales in the current year compared to 16.1%
for the same period last year. These increases were largely due to hiring and
training costs associated with the opening of 19 new stores during the quarter,
as well as significant grand opening advertising costs associated with the entry
into the San Francisco market. The pre-opening costs of approximately $450,000
per store plus the grand opening advertising expenses increased second quarter
SG&A expenses by approximately $13 million, or 0.5% of sales, compared to the
same period last year. Of the 19 new stores opened in the current year's second
quarter, ten were opened in the last month of the quarter. As a result, the
benefits of the pre-opening costs incurred in opening those stores will not be
fully realized until the second half of the year. The remainder of the increase
in SG&A spending was due principally to expenses incurred to support the
Company's increased expansion plans, as well as investments in personnel and
strategic initiatives expected to produce longer-term benefits. These costs
include training and development of retail store management, developing the
Company's e-commerce business and enhancing systems that support retail and
service operations. Excluding the impact of the new store opening costs, SG&A
expenses as a percentage of gross margin declined to 80% in the second quarter
as compared to 82% in the second quarter last year, and operating margin
improved to 3.9% compared to 3.3% in the same quarter one year ago. This
leverage is consistent with management's intent to fund expansion and business
improvement initiatives through increased gross profit margins. Management
currently expects that SG&A spending will continue to increase on a
year-over-year basis. Higher sales volumes in the second half of the year,
combined with higher year-over-year gross margin rates, are expected to result
in improved operating income margins in the second half of the year.

Net interest income was $4.3 million in the second quarter and $8.7 million
year-to-date compared to net interest expense of $1.0 million and $3.5 million,
respectively, in the same periods last year. These improvements were principally
due to the early retirement of the Company's $150 million 8-5/8% Senior
Subordinated Notes in the third quarter of fiscal 1999 and the conversion into
equity of the Company's $230 million in preferred securities in the first
quarter of fiscal 1999. Interest earned on higher cash balances resulting from
faster inventory turns and earnings over the past four quarters in excess of
$270 million also contributed to the improvement.

The Company's effective income tax rate for the second quarter was 38.1%,
compared to 38.5% for the same quarter a year ago and 38.3% year-to-date
compared to 38.5% for the year-to-date period last year. The Company's effective
tax rate is primarily impacted by the taxability of investment income and state
income taxes. Management's revised estimate of the annual effective tax rate of
38.3% for fiscal 2000 reflects higher levels of tax-exempt interest income. This
revised annual estimate resulted in an effective rate of 38.1% in the second
quarter.

FINANCIAL CONDITION

Working capital of $681 million at August 28, 1999 improved from $589 million a
year ago. Cash and cash equivalents decreased by only $18 million compared to
one year ago even with the retirement of over $180 million in debt, the
repurchase of $100 million of the Company's common stock and the investment in
new stores, corporate facilities and other initiatives to grow the business.
Cash and cash equivalents decreased by $312 million compared to February 27,
1999, primarily due to investment in new stores and corporate facilities and the
repurchase of $98 million of the Company's common stock in the first half of
fiscal 2000. Merchandise inventories increased by $120 million compared to the
second quarter last year, or 10%, while the number of stores open at the end of
the second quarter increased by 15% and sales increased by 23% as inventory
turns continued to improve. The rolling twelve month inventory turns improved
nearly one full turn to 7.0 times for the period ended August 28, 1999, compared
to 6.1 times for the period ended August 29, 1998. The Company's net investment
in inventory, inventory net of accounts payable, was $229 million at August 28,
1999, down from $308 million at

                                       12


August 29, 1998. Merchandise inventories increased by $241 million compared
to February 27, 1999, largely due to seasonality and the net addition of 21
stores in the first six months of fiscal 2000. The Company's cash position
and net investment in inventory are impacted by the timing of payments to
vendors and can vary significantly. Receivables increased by $38 million as
compared to a year ago and $46 million compared to last fiscal year-end
primarily due to higher business volumes including amounts due from the ISP
subsidy provider. Recoverable costs from developed properties increased by
$42 million compared to last year primarily due to the development of new
stores. Other assets and long-term liabilities both increased due to the
Company's deferred compensation plan, established in fiscal 1999. Accounts
payable increased as compared to a year ago and last fiscal year-end as a
result of the higher business volume and increased inventory levels. Accruals
for payroll related liabilities increased as compared to last year's second
quarter consistent with an expanding employee base needed to support the
Company's growth, but decreased versus the prior fiscal year-end due to the
payment of fiscal 1999 bonuses. Other accrued liabilities increased compared
to August 29, 1998, as a result of the overall higher levels of business
activity.

Capital spending in the first six months of fiscal 2000 was $145 million
compared to $31 million for the same period last year as the Company invested in
the 22 stores opened during the first six months and the 23 additional stores
slated to open in the third quarter of fiscal 2000. Additionally, the Company
invested in expanding its corporate facilities to support the growth of the
business, the most significant investment being the purchase of an additional
office building to supplement the Company's existing corporate office. The
Company also continued to invest in new systems and technology to better
position the Company for continued growth and generate improvements in its
existing business.

Management expects total capital spending for fiscal 2000 to be approximately
$400 million, exclusive of amounts expected to be recovered through
subsequent sales and leasebacks, related to the Company's 45 new stores and
13 remodeled, expanded or relocated stores in fiscal 2000. Capital spending
for the current year also includes expenditures required to support the
Company's plans to open 55 to 60 stores in fiscal 2001, as well as further
expansion of the Company's corporate headquarters capacity. In addition, the
Company continues to invest in information systems to support the development
of its e-commerce business and to improve its Services division.

In October 1998, the Company's Board of Directors authorized the purchase of up
to $100 million of the Company's common stock over a twelve month period. This
repurchase program was completed in the second quarter of fiscal 2000 as the
Company purchased a total of 1.8 million shares. In September 1999, the Board
authorized the purchase of up to an additional $200 million of the Company's
common stock.

In August 1999, the Company entered into an unsecured $100 million revolving
credit facility, replacing the $220 million facility that was scheduled to
mature in June 2000. The Company was able to reduce the size of the facility due
to improved operating performance and better inventory management. In addition,
the new facility makes certain financial covenants less restrictive thereby
providing the Company with additional flexibility. The current facility is
scheduled to mature in August 2002.

Management believes that funds from the expected results of operations, and
available cash and cash equivalents will be sufficient to support the Company's
anticipated expansion plans and strategic initiatives for the next year. The
revolving credit facility and the Company's inventory financing program are also
available for additional working capital needs or opportunities.

YEAR 2000 READINESS

The Company recognized the material nature of the business issues surrounding
computer processing of dates into and beyond the year 2000 (Y2K) and began
taking corrective action in 1997. The Company's actions to address Y2K issues
began with the selection of a nationally recognized, experienced computer
hardware and consulting firm to assist in both identifying and resolving these
issues. The Company developed specific and detailed plans to correct Y2K issues
and management believes the Company has essentially completed all of the
activities within its control to ensure the Company's systems are Y2K compliant.
The Company has funded both the capital and expensed elements of resolving Y2K
issues through funds generated from operations.

The majority of the Company's business processing applications operate on
mainframe computer systems. The Company has replaced and tested all of the
existing computer code effected by Y2K issues and the Company's

                                       13


mainframe systems are fully functional in its current fiscal year 2000, which
began February 28, 1999. This portion of the Company's plan was completed
last fiscal year at a cost of approximately $9 million in outside
professional fees.

The Company has completed efforts to identify non-mainframe computer system Y2K
issues and other potential Y2K issues. These issues include the Company's
communication systems and operating systems at and between the Company's
retail locations and support facilities. This portion of the Company's plan was
completed at a total cost of approximately $9 million, with the majority
incurred in the current year.

The Company has replaced or installed certain non-mainframe computer hardware
and software that addressed new business application needs, as well as Y2K
issues. The timing was accelerated for certain projects to meet Y2K
compliance. The only implementation activities remaining are implementation
testing of the systems that support the Company's Services division and the
in-store register system. Testing for both systems is expected to be
completed during the third quarter.

The Company has communicated with its business partners, including significant
merchandise suppliers and service providers to assess their ability to support
the Company's operations with respect to their individual Y2K issues. These
issues include data exchange with the Company, as well as the business partners'
ability to maintain their production and shipping processes. The issues that
were identified as part of this assessment have been prioritized in order of
significance to the Company's operations and corrective actions are being taken
as appropriate. All assessments have been scored and rated according to the risk
to the Company's business. Both the Company's business partners and the
Company's Y2K technical team collaborated on the ratings. To date, all of the
Company's business partners deemed to have a potential material impact on the
Company's operations have been assessed. Action plans were developed for each
business partner that posed a material risk to the Company's ongoing operations.
Actions, which include working with existing vendors to maintain the supply
chain, will be taken through the end of the calendar year to minimize these
risks.

The Company has also documented and reviewed the key internal processes
required to operate its business. Each process was examined to determine if
systems or third-party Y2K failures could impact the Company's business
operations. Contingency plans to deal with potential business disruptions
caused by Y2K failures will be completed in the third quarter. To further
prepare for possible disruptions, the Company has planned a series of century
change preparation activities including the creation of a Y2K internal call
center to centrally manage Y2K events and support remote operations.

The Company generally believes that the vendors that supply products to the
Company for resale are responsible for the Y2K functionality of those products.
However, should product failures occur, the Company may be required to address
certain aspects of those failures such as handling product returns or repairs.
Actions to address this risk is included in the Company's contingency plans.

While the Company believes that it is pursuing the appropriate course of
action to ensure Y2K readiness, there can be no assurance that the objective
will be achieved either internally or as it relates to its business partners.
Also, the Company can provide no assurance regarding potential impact on
consumer spending that may result from concerns regarding the Y2K
functionality of products. For the Y2K issues which, if not timely resolved,
could have a significant impact on the Company's operations, the Company is
continuing to develop contingency plans to minimize the impact of failure to
achieve Y2K compliance. The Company has also devoted significant attention to
planning for what could be the result of the most adverse consequence of Y2K
issues including infrastructure failure or failure of core internal process
systems. Management believes that appropriate actions have been taken to
minimize the financial impact to the Company.
