1.   Basis of Presentation

The  accompanying  unaudited  condensed  consolidated  financial  statements  of
O'Reilly Automotive, Inc. and Subsidiaries (the "Company") have been prepared in
accordance with accounting  principles  generally  accepted in the United States
for interim financial  information and the instructions to Form 10-Q and Article
10 of Regulation  S-X.  Accordingly,  they do not include all of the information
and footnotes required by accounting principles generally accepted in the United
States for complete  financial  statements.  In the opinion of  management,  all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair  presentation  have been  included.  Operating  results for the nine months
ended  September  30,  2004,  may not be  indicative  of the results that may be

the  consolidated  financial  statements and footnotes  thereto  included in the

2.   Stock-based Compensation

The Company has elected to use the  intrinsic  value  method of  accounting  for
stock  options  issued  under our stock option  plans and  accordingly  does not
record an expense for such stock options.  For purposes of pro forma disclosures
under  the fair  value  method,  the  estimated  fair  value of the  options  is
amortized to expense over the options'  vesting period.  The Company's pro forma
information is as follows:

3.   Synthetic Lease Facility

On June 26, 2003, we completed an amended and restated master agreement relating
to our properties leased from SunTrust Equity Funding, LLC ("the Facility"). The
terms of the amended and restated  Facility  provide for an initial lease period
of five years,  a residual  value  guarantee of  approximately  $44.2 million at
September 30, 2004, and purchase  options on the  properties.  The Facility also
contains a provision  for an event of default  whereby  the lessor,  among other
things, may require us to purchase any or all of the properties.  One additional
renewal  period of five years may be  requested  from the lessor,  although  the
lessor is not  obligated to grant such  renewal.  The  agreement  with  SunTrust
Equity  Funding,  LLC has been recorded and  disclosed as an operating  lease in
accordance with Financial  Accounting  Standards Board ("FASB") Statement No. 13
and FASB  Interpretation  No. 46,  "Consolidation of Variable Interest Entities"
and FASB Interpretation No. 46R.

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

Unless  otherwise  indicated,  "we," "us," "our" and similar  terms,  as well as
references to the "Company" or "O'Reilly" refer to O'Reilly Automotive, Inc. and
its subsidiaries.

Critical Accounting Policies and Estimates

The  fundamental   objective  of  financial   reporting  is  to  provide  useful
information  that allows a reader to comprehend  the business  activities of our
company. To aid in that  understanding,  management has identified our "critical
accounting  policies."  These  policies  have  the  potential  to  have  a  more
significant  impact  on  our  financial   statements,   either  because  of  the
significance  of the financial  statement item to which they relate,  or because
they  require  judgment  and  estimation  due to  the  uncertainty  involved  in
measuring, at a specific point in time, events which are continuous in nature.

o    Cost of goods sold - Cost of goods sold includes warehouse and distribution
     expenses and estimates of amounts due from vendors for certain  merchandise
     allowances  and rebates.  These  estimates are consistent  with  historical
     experience.

o    Operating, selling, general and administrative expense (OSG&A) - Operating,
     selling, general and administrative expense includes estimates for medical,
     workers'  compensation and other general liability  obligations,  which are
     partially  based  on  estimates  of  certain  claim  costs  and  historical
     experience.

o    Accounts receivable - Allowance for doubtful accounts is estimated based on
     historical  loss  ratios  and  consistently  has been  within  management's
     expectations.

o    Revenue -  Over-the-counter  retail  sales are  recorded  when the customer
     takes  possession of merchandise.  Sales to professional  installers,  also
     referred  to  as   "commercial   sales,"  are  recorded  upon  delivery  of
     merchandise to the customer, generally at the customer's place of business.
     Wholesale sales to other retailers,  also referred to as "jobber sales" are
     recorded  upon  shipment  of  merchandise.  All sales are  recorded  net of
     estimated allowances and discounts.

o    Vendor  concessions  - The Company  receives  concessions  from its vendors
     through a variety of  programs  and  arrangements,  including  co-operative
     advertising,   allowances  for  warranties  and  volume  purchase  rebates.
     Co-operative advertising allowances that are incremental to our advertising
     program,  specific to a product or event and  identifiable  for  accounting
     purposes are reported as a reduction of  advertising  expense in the period
     in which  the  advertising  occurred.  All  other  vendor  concessions  are
     recognized  as a  reduction  of  cost  of  sales  when  recognized  in  the
     consolidated statement of income.

o    Stock-based  compensation  - We have  elected  to use the  intrinsic  value
     method of accounting  for stock options issued under our stock option plans
     and  accordingly  do not record an  expense  for such  stock  options.  For
     purposes  of pro  forma  disclosures  under  the  fair  value  method,  the
     estimated  fair value of the  options  is  amortized  to  expense  over the
     options' vesting period. Our pro forma information is as follows:

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

Results of Operations

Product sales for the third quarter of 2004 were $ 455.2 million, an increase of
$43.0 million or 10.4% over product sales for the third quarter of 2003. Product
sales for the first  nine  months of 2004 were $1.29  billion,  an  increase  of
$148.9  million or 13.0% over  product  sales for the first nine months of 2003.
These  increases  are  primarily due to the opening of 35 net, new stores during
the third quarter of 2004 and 96 net, new stores during the first nine months of
2004, in addition to a 3.4% and 6.2% increase in comparable  store product sales
(1) for the third  quarter  and first  nine  months  of 2004,  respectively.  At
September  30,  2004,  we operated  1,205  stores  compared  to 1,074  stores at
September 30, 2003.

Gross profit  increased 11.5% from $175.7 million (or 42.6% of product sales) in
the third quarter of 2003 to $195.8  million (or 43.0% of product  sales) in the
third quarter of 2004.  Gross profit for the first nine months  increased  14.6%
from $482.3  million (or 42.1% of product  sales) in 2003 to $552.9  million (or
42.7% of  product  sales) in 2004.  The  increase  in gross  profit  dollars  is
primarily a result of the increase in the number of stores open during the third
quarter and first nine months of 2004 compared to the same periods in 2003,  and
increased  sales  levels at existing  stores.  The increase in gross profit as a
percentage  of product  sales in the third  quarter  2004  compared to 2003,  is
primarily due to a reduction in the cost of  merchandise  from our vendors.  The
increase in gross  profit as a  percentage  of product  sales for the first nine
months of 2004  compared to 2003, is primarily due to a reduction in the cost of
merchandise from vendors and a reduction in warehouse and delivery expenses as a
percentage of product sales.

Operating,  selling,  general and  administrative  expenses  ("OSG&A  expenses")
increased  $14.7 million from $127.3  million (or 30.9% of product sales) in the
third quarter of 2003 to $142.0 million (or 31.2% of product sales) in the third
quarter of 2004. OSG&A expenses  increased $46.9 million from $355.9 million (or
31.1% of product  sales) in the first nine months of 2003 to $402.8  million (or
31.1% of product sales) in the first nine months of 2004. The dollar increase in
OSG&A expenses resulted from the addition of team members and resources in order
to support the  increased  level of our  operations.  The increase in OSG&A as a
percentage  of product  sales in the third  quarter of 2004 compared to 2003, is
primarily due to increased labor and benefit expenses and a lack of leverage due
to lower than anticipated sales.

Other expense decreased by $388,000 in the third quarter of 2004 compared to the
third quarter of 2003 and decreased by $2.9 million for the first nine months of
2004  compared to the first nine months of 2003.  The  decreases in both periods
being compared were  primarily due to decreases in interest  expense as a result
of lower borrowings under our credit facility.

Our estimated provision for income taxes increased $2.1 million and $9.8 million
for the third quarter and first nine months of 2004,  respectively,  compared to
the same  periods in 2003,  as a result of our  increased  taxable  income.  Our
effective tax rate was 37.3% of income before income taxes for the third quarter
and  first  nine  months  of 2004,  compared  with  37.4% and 37.5% for the same
periods of 2003, respectively.

Principally,  as a result of the  foregoing,  net  income  increased  from $29.5
million (or 7.2% of product sales) in the third quarter of 2003 to $33.2 million
(or 7.3% of product  sales) in the third quarter of 2004.  Net income  increased
from $76.2  million (or 6.7% of product  sales) in the first nine months of 2003
to $93.0 million (or 7.2% of product sales) in the first nine months of 2004.



(1)  Comparable  store  product  sales  are  calculated  based on the  change in
     product  sales of stores  open at least one year.  Percentage  increase  in
     comparable  store product sales is calculated based on store sales results,
     which exclude sales of specialty  machinery,  sales by outside salesmen and
     sales to employees.

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

Liquidity and Capital Resources

Net cash provided by operating  activities increased from $167.5 million for the
first nine  months in 2003 to $196.3  million for the first nine months of 2004.
This increase was principally the result of increased net income, an increase in
accounts  payable and a decrease in amounts  receivable from vendors,  partially
offset by  increases  in  inventory  and  accounts  receivable.  The increase in
accounts  payable is primarily  attributable  to the timing of payments and more
favorable payment terms from vendors. The increases in inventory and receivables
are primarily due to our increased  product sales  resulting from our continuing
store growth.

Net cash used in investing  activities  increased  from $99.2 million during the
first nine months in 2003 to $123.2 million for the  comparable  period in 2004,
primarily  due to the increased  purchases of property and  equipment  resulting
from new store growth.

Net cash used in financing activities was $10.5 million in the first nine months
of 2004,  compared  to $64.5  million  in the first  nine  months  of 2003.  The
decrease in net cash used in  financing  activities  is  primarily  due to lower
repayments of long-term debt.

We have available an unsecured,  three-year syndicated revolving credit facility
in the amount of $150 million.  The credit  facility is guaranteed by all of our
subsidiaries  and may be  increased  to a  total  of $200  million,  subject  to
availability  of such  additional  credit from either  existing banks within the
syndicate or other banks.  At September 30, 2004,  none of the revolving  credit
facility  was  outstanding.  Letters  of  credit  totaling  $18.6  million  were
outstanding at September 30, 2004.  Accordingly,  we have aggregate availability
for additional borrowings of $131.4 million under the revolving credit facility.
The  revolving  credit  facility,  which  bears  interest at LIBOR plus a spread
ranging from 0.875% to 1.375%  (2.25% at September  30,  2004),  expires in July
2005.

Our continuing store expansion program requires significant capital expenditures
and working capital principally for inventory requirements. The costs associated
with  the  opening  of a new  store  (including  the  cost of land  acquisition,
improvements,  fixtures,  inventory  and computer  equipment)  are  estimated to
average  approximately  $900,000  to $1.1  million;  however,  such costs may be
significantly  reduced  where we lease,  rather than  purchase,  the store site.
Although the cost to acquire the business of an independently  owned parts store
varies, depending primarily upon the amount of inventory and the amount, if any,
of real estate being acquired, we estimate that the average cost to acquire such
a  business  and  convert  it to one of our  stores is  approximately  $400,000,
exclusive of the cost of  inventory.  We plan to finance our  expansion  program
through cash expected to be provided  from  operating  activities  and available
borrowings under our existing credit facilities.

During the first  nine  months of 2004,  96 net,  new stores  were  opened.  The
Company  plans to open 44 additional  stores  during the remainder of 2004.  The
funds  required  for such  planned  expansions  are  expected  to be provided by
operating activities and the existing and available bank credit facilities.

We believe that our existing cash, short-term  investments,  cash expected to be
provided by operating  activities,  available  bank credit  facilities and trade
credit will be sufficient to fund both our short-term and long-term  capital and
liquidity needs for the foreseeable future.

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

Inflation and Seasonality

We have been  successful,  in many cases, in reducing the effects of merchandise
cost increases  principally by taking  advantage of vendor  incentive  programs,
economies of scale  resulting from  increased  volume of purchases and selective
forward  buying.  As a  result,  we do not  believe  our  operations  have  been
materially affected by inflation.

Our  business is seasonal to some extent  primarily as a result of the impact of
weather  conditions  on store sales.  Store sales and profits have  historically
been higher in the second and third quarters  (April through  September) of each
year than in the first and fourth quarters.

Internet Address and Access to SEC Filings

Our Internet address is  www.oreillyauto.com.  Interested readers can access the
Company's annual reports on Form 10-K,  quarterly reports on Form 10-Q,  current
reports on Form 8-K,  and any  amendments  to those  reports  filed or furnished
pursuant to Section  13(a) or 15(d) of the  Securities  Exchange Act of 1934, as
amended,  through the Securities and Exchange Commission  website,  www.sec.gov.
Such reports are  generally  available on the day they are filed.  Additionally,
the Company will furnish  interested  readers upon request and free of charge, a
paper copy of such reports.

Forward-Looking Statements

We claim the protection of the safe-harbor for forward-looking statements within
the meaning of the Private  Securities  Litigation  Reform Act of 1995.  Certain
statements  contained within this filing discuss,  among other things,  expected
growth, store development and expansion strategy,  business  strategies,  future
revenues and future performance.  These forward-looking  statements are based on
estimates, projections, beliefs and assumptions and are not guarantees of future
events and results.  Such  statements  are subject to risks,  uncertainties  and
assumptions,  including,  but not limited to,  competition,  product demand, the
market for auto parts, the economy in general, inflation,  consumer debt levels,
governmental  approvals,  our  ability to hire and retain  qualified  employees,
risks associated with the integration of acquired businesses, weather, terrorist
activities, war and the threat of war. Actual results may materially differ from
anticipated results described in these forward-looking statements.  Please refer
to Exhibit 99.1 and the Risk Factors sections of the Company's Form 10-K for the
year ended December 31, 2003, for more details.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are  subject  to  interest  rate risk to the  extent we  borrow  against  our
revolving  credit facility with variable  interest rates.  Since no amounts were
outstanding  under the revolving credit facility at September 30, 2004,  changes
in interest  rates would not have any effect.  In the event of an adverse change
in interest  rates and  assuming the Company had amounts  outstanding  under the
credit  facility,  management  would likely take actions that would mitigate our
exposure to interest rate risk  particularly if our borrowing levels increase to
any significant extent.

ITEM 4.  CONTROLS AND PROCEDURES

The Company's  management,  under the supervision and with the  participation of
our chief  executive  officer and chief  financial  officer,  has  reviewed  and
evaluated the effectiveness of the Company's  disclosure controls and procedures
as of  September  30,  2004.  Based on such  review  and  evaluation,  our chief
executive officer and chief financial officer have concluded that the disclosure
controls and procedures  were effective as of September 30, 2004, to ensure that
the  information  required to be disclosed by the Company in the reports that it
files or submits under the Securities  Exchange Act of 1934, as amended,  (a) is
recorded, processed, summarized and reported within the time period specified in
the  SEC's  rules  and  forms and (b) is  accumulated  and  communicated  to the
Company's  management,  including the officers,  as  appropriate to allow timely
decisions regarding required  disclosure.  There were no material changes in the
Company's internal controls over financial reporting during the third quarter of
2004 that have materially affected or are reasonably likely to materially affect
the Company's internal controls over financial reporting.

                       Exhibit 99.1 - Certain Risk Factors


Some of the  information in this Form 10-Q contains and future reports and press
releases and other public  information  may contain  forward-looking  statements
that  involve  substantial  risks  and  uncertainties.  You can  identify  these
statements  by   forward-looking   words  such  as  "may,"   "will,"   "expect,"
"anticipate,"  "believe,"  "estimate,"  and "continue" or similar  words.  These
"forward-looking   statements"  are  made  in  reliance  upon  the  safe  harbor
provisions of the Private Securities  Litigation Reform Act of 1995 (See Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934.) You should read statements that contain these words carefully  because
they: (1) discuss our future expectations; (2) contain projections of our future
results  of  operations  or of  our  financial  condition;  or (3)  state  other
"forward-looking"  information.  We believe it is important to  communicate  our
expectations to our investors.  However,  there may be events in the future that
we are not able to accurately predict or over which we have no control.

The risk factors listed in this exhibit,  as well as any cautionary  language in
this Form 10-Q, are subject to risks, uncertainties and assumptions,  including,
but not limited to, competition,  product demand, the market for auto parts, the
economy in general, inflation, consumer debt levels, governmental approvals, our
ability  to hire and  retain  qualified  employees,  risks  associated  with the
integration of acquired business,  weather,  terrorist  activities,  war and the
threat of war.  Actual results may materially  differ from  anticipated  results
described  in these  forward-looking  statements.  You  should be aware that the
occurrence  of the events  described in these risk factors and  elsewhere in our
annual report on Form 10-K for the year ended  December 31, 2003 (the "2003 Form
10-K") could have a material adverse effect on our business,  operating  results
and financial condition.

Competition

We  compete  with a large  number of retail  (DIY) and  wholesale  (professional
installers)  automotive  aftermarket  product  suppliers.  The  distribution  of
automotive  aftermarket products is a highly competitive industry,  particularly
in the more densely  populated market areas that we serve.  Competitors  include
national and regional automotive parts chains,  independently owned parts stores
(some  of  which  are  associated  with  national  auto  parts  distributors  or
associations), automobile dealerships, mass or general merchandise, discount and
convenience  chains  that  carry  automotive  products,   independent  warehouse
distributors   and  parts  stores  and  national   warehouse   distributors  and
associations.  Some of our  competitors  are larger than we are and have greater
financial  resources.  In addition,  some of our competitors are smaller than we
are overall but have a greater presence than we do in a particular market. For a
list of our principal  competitors,  see the "Competition"  section of Item 1 to
our 2003 Form 10-K.

No Assurance of Future Growth

We believe that our ability to open  additional  stores at an  accelerated  rate
will be a significant  factor in achieving our growth objectives for the future.
Failure to achieve our growth objectives may negatively impact the trading price
of our  common  stock.  Our  ability to  accomplish  our  growth  objectives  is
dependent,  in part, on matters beyond our control,  such as weather conditions,
zoning and other issues related to new store site development,  the availability
of qualified  management personnel and general business and economic conditions.
We cannot be sure that our growth  plans for 2004 and beyond  will be  achieved.
For a  discussion  of our growth  strategies,  see the  ''Growth  and  Expansion
Strategies'' section of Item 1 to our 2003 Form 10-K.

Acquisitions May Not Lead to Expected Growth

We expect to continue to make acquisitions as an element of our growth strategy.
Acquisitions  involve certain risks that could cause our actual growth to differ
from  our  expectations.  For  example:  (1) we may not be able to  continue  to
identify suitable  acquisition  candidates or to acquire additional companies at
favorable prices or on other favorable terms; (2) our management's attention may
be  distracted;  (3) we may fail to retain key  acquired  personnel;  (4) we may
assume unanticipated legal liabilities and other problems; and (5) we may not be
able to successfully integrate the operations (accounting and billing functions,
for example) of businesses we acquire to realize economic, operational and other
benefits.

                 Exhibit 99.1 - Certain Risk Factors (continued)

Sensitivity to Regional Economic and Weather Conditions

All of our stores are located in the  Central and  Southern  United  States.  In
particular, approximately 32% of our stores are located in Texas. Therefore, our
business is sensitive to the economic and weather  conditions of these  regions.
Unusually severe or inclement weather tends to reduce sales, particularly to DIY
customers.

Dependence Upon Key and Other Personnel

Our success has been largely  dependent on the efforts of certain key personnel,
including  David O'Reilly,  Ted Wise, Greg Henslee and Jim Batten.  Our business
and results of operations could be materially  adversely affected by the loss of
the services of one or more of these individuals.  Additionally,  our successful
implementation and management of our growth and expansion strategies will depend
on our ability to continue to attract and retain qualified personnel.  We cannot
be sure  that we will be able to  continue  to  attract  such  personnel.  For a
further discussion of our management and personnel, see the ''Business'' section
of Item 1 and Item 4a of our 2003 Form 10-K and our Proxy  Statement on Schedule
14A for the 2004 Annual Meeting of Shareholders.

Concentration of Ownership by Management

Our executive  officers and directors as a group  beneficially own a substantial
percentage of the  outstanding  shares of our common stock.  These  officers and
directors have the ability to exercise  effective voting control of the company,
including the election of all of our directors, and to effectively determine the
vote on any matter  being voted on by our  shareholders,  including  any merger,
sale of assets or other change in control of the company.

Possible Volatility of Our Stock Price

The stock  market and the price of our common  stock may be subject to  volatile
fluctuations based on general economic and market  conditions.  The market price
for our common  stock may also be  affected  by our  ability  to meet  analysts'
expectations.  Failure to meet such expectations,  even slightly,  could have an
adverse  effect on the market  price of our common  stock.  In  addition,  stock
market  volatility  has  had a  significant  effect  on  the  market  prices  of
securities  issued by many  companies  for reasons  unrelated  to the  operating
performance of these companies.  In the past, following periods of volatility in
the market price of a company's  securities,  securities class action litigation
has often been  instituted  against such a company.  If similar  litigation were
instituted  against us, it could result in substantial  costs and a diversion of
our management's attention and resources,  which could have an adverse effect on
our business.

Shares Eligible for Future Sale

All of the shares of common stock  currently  held by our affiliates may be sold
in reliance upon the exemptive  provisions of Rule 144 of the  Securities Act of
1933, as amended, subject to certain volume and other conditions imposed by such
rule.  We cannot  predict the  effect,  if any,  that future  sales of shares of
common stock or the availability of such shares for sale will have on the market
price of the common stock  prevailing  from time to time.  Sales of  substantial
amounts of common stock,  or the perception  that such sales might occur,  could
adversely affect the prevailing market price of the common stock.
