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, 2003, are not necessarily indicative of the results that may
be expected for the year ended December 31, 2003. For further information, refer
to the consolidated  financial  statements and footnotes thereto included in the
Company's Annual Report on Form 10-K for the year ended December 31, 2002.

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 to our
$50 million Synthetic  Operating Lease Facility ("the Facility") with a group of
financial  institutions.  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, 2003 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
amended and restated Facility has been accounted for as an operating lease under
the   Financial   Accounting   Standards   Board   Statement   13  and   related
Interpretations.

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

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  estimates  of  shortages
     that are adjusted upon physical  inventory counts in subsequent periods and
     estimates of amounts due from vendors for certain  merchandise  allowances,
     warranties  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 worker's compensation and other general liability obligations,  some of
     which are partially  self-insured.  Such  estimates are partially  based on
     estimates of certain claim costs and historical experience.

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

o    Revenue - We recognize sales upon shipment of the products.

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 2003 were $412.2 million,  an increase of
$52.6 million or 14.6% over product sales for the third quarter of 2002. Product
sales for the first  nine  months of 2003 were $1.14  billion,  an  increase  of
$146.5  million or 14.7% over  product  sales for the first nine months of 2002.
These  increases  are  primarily due to the opening of 33 net, new stores during
the third quarter of 2003 and 93 net, new stores during the first nine months of
2003, in addition to a 8.3% and 7.2% increase in comparable  store product sales
for the third quarter and first nine months of 2003, respectively.  At September
30, 2003, we operated 1,074 stores compared to 958 stores at September 30, 2002.

Gross profit  increased 15.4% from $152.2 million (or 42.3% of product sales) in
the third quarter of 2002 to $175.7  million (or 42.6% of product  sales) in the
third quarter of 2003.  Gross profit for the first nine months  increased  14.2%
from $422.4  million (or 42.3% of product  sales) in 2002 to $482.3  million (or
42.1% of  product  sales) in 2003.  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 2003  compared to the same period of 2002,  and
increased  sales  levels at existing  stores.  The increase in gross profit as a
percentage  of product  sales in the third  quarter  2003  compared to 2002,  is
primarily due to a reduction in the cost of  merchandise  from our vendors.  The
decrease in gross  profit as a  percentage  of product  sales for the first nine
months of 2003  compared to 2002,  is primarily  due to increased  warehouse and
delivery expenses resulting from the Company's  remodeling of it's Nashville and
Knoxville,  TN  distribution  centers,  which  occured  in the first and  second
quarters of 2003.


Operating,  selling,  general and  administrative  expenses  ("OSG&A  expenses")
increased  $15.8 million from $111.5  million (or 31.0% of product sales) in the
third quarter of 2002 to $127.3 million (or 30.9% of product sales) in the third
quarter of 2003. OSG&A expenses  increased $40.6 million from $315.3 million (or
31.6% of product  sales) in the first nine months of 2002 to $355.9  million (or
31.1% of product sales) in the first nine months of 2003. 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 decrease in OSG&A as a
percentage of product sales is primarily due to economies of scale  achieved and
the result of management's efforts to increase labor productivity.

Other  expenses  decreased by $793,000 in the third  quarter of 2003 compared to
the third quarter of 2002 and decreased by $776,000 for the first nine months of
2003  compared to the first nine months of 2002.  The  decreases in both periods
being compared were primarily due to decreases in interest expense.

Our estimated provision for income taxes increased $3.0 million and $7.2 million
for the  third  quarter  and  first  nine  months  of  2003  compared  to  2002,
respectively,  as a result of our increased  taxable  income.  Our effective tax
rate was 37.4% and 37.5% of income before income taxes for the third quarter and
first nine months of 2003  respectively,  compared  with 37.9% and 37.8% for the
same periods of 2002, respectively.

Principally,  as a result of the  foregoing,  net  income  increased  from $24.1
million or 6.7% of product  sales in the third  quarter of 2002 to $29.5 million
or 7.2% of product sales in the third quarter of 2003. Net income increased from
$63.3 million or 6.3% of product sales in the first nine months of 2002 to $76.2
million or 6.7% of product sales in the first nine months of 2003.

Liquidity and Capital Resources

Net cash provided by operating  activities increased from $105.1 million for the
first nine  months in 2002 to $172.1  million for the first nine months of 2003.
This increase was  principally  the result of increased net income and increases
in accounts  payable and income taxes payable,  partially offset by increases in
inventory, accounts receivable and amounts receivable from vendors. The increase
in accounts payable is primarily attributable to the timing of payments and more
favorable  payment terms from  vendors.  The increase in income taxes payable is
primarily  due to the  timing  of  payments.  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 $72.4 million during the
first nine months in 2002 to $103.9 million for the  comparable  period in 2003,
primarily  due to the increased  purchases of property and  equipment  resulting
from new store growth.

Net cash used in financing activities was $64.5 million in the first nine months
of 2003,  compared  to $15.9  million  in the first  nine  months  of 2002.  The
increase  in net  cash  used  in  financing  activities  is  primarily  due to a
reduction in long-term debt.

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

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 at any time prior
to January 29, 2004,  subject to  availability  of such  additional  credit from
either  existing  banks within the  syndicate or other banks.  At September  30,
2003,   $10.0  million  of  the  revolving   credit  facility  was  outstanding.
Additionally,  letters of credit  totaling  $9.8  million  were  outstanding  at
September 30, 2003.  Accordingly,  we have aggregate availability for additional
borrowings of $130.2  million under the credit  facility.  The credit  facility,
which bears interest at LIBOR plus a spread ranging from 0.875% to 1.375% (2.00%
at September 30, 2003), expires in July 2005.

On June 26, 2003, we completed an amended and restated  master  agreement to our
$50 million Synthetic  Operating Lease Facility ("the Facility") with a group of
financial  institutions.  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, 2003, 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
amended and restated Facility has been accounted for as an operating lease under
the Financial Accounting  Standards Board  Interpretation 46,  "Consolidation of
Variable Interest Entities."

In August 2001, we completed a sale-leaseback with  O'Reilly-Wooten 2000 LLC (an
entity owned by certain shareholders of the Company).  The transaction closed on
September 1, 2001, with a purchase price of approximately  $5.6 million for nine
O'Reilly  Auto Parts stores and did not result in a material  gain or loss.  The
lease,  which has been accounted for as an operating lease, calls for an initial
term of 15 years with three five-year renewal options.

On May 16, 2001, we completed a $100 million private  placement of two series of
unsecured  senior notes  ("Senior  Notes").  The Series 2001-A Senior Notes were
issued for $75  million,  are due May 16, 2006,  and bear  interest at 7.72% per
year.  The Series 2001-B  Senior Notes were issued for $25 million,  are due May
16, 2008, and bear interest at 7.92% per year. The private  placement  agreement
allows for a total of $200 million of Senior Notes issuable in series.  Proceeds
from the  transaction  were  used to  reduce  outstanding  borrowings  under our
revolving credit facility.

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.

For the first nine months of 2003,  93 net, new stores were opened.  The Company
plans to open 34  additional  stores  during the  remainder  of 2003.  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.

New Accounting Standards

In March 2003,  the  Emerging  Issues Task Force  (EITF)  reached a consensus on
Issue No.  02-16,  Accounting  by a Customer  (including a Reseller) for Certain
Consideration Received from a Vendor. Under the new guidance, cash consideration
received from a vendor should be classified as a reduction of cost of sales.  If
the  consideration  received  represents  a payment for assets  delivered to the
vendor,  it  should  be  classified  as  revenue.  If  the  consideration  is  a
reimbursement of a specific, incremental,  identifiable cost incurred in selling
the vendor's  product,  the cost should be  characterized as a reduction of that
cost  incurred.  The guidance is effective for fiscal  periods  beginning  after
December 15,  2002.  The  adoption of this  guidance did not have a  significant
impact on our consolidated financial position or results of operations.

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.

RESULTS OF OPERATIONS AND FINANCIAL CONDITION (CONT.)

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 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
contained  in the  Private  Securities  Litigation  Reform  Act of  1995.  These
statements 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 and
regulations,   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 the Risk Factors  section in Exhibit 99.1 and the Company's Form 10-K for the
year ended December 31, 2002, 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 credit
facility  because of its variable  interest rate.  Assuming the current level of
borrowings at variable rates and assuming a  two-percentage  point change in the
average interest rates under these borrowings, it is estimated that our interest
expense for the quarter  ended  September  30,  2003,  would have  increased  by
approximately  $50,000.  In the event of an adverse  change in  interest  rates,
management  would  likely  take  actions  that would  mitigate  our  exposure to
interest  rate  risk  particularly  if  our  borrowing  levels  increase  to any
significant extent; however, due to the uncertainty of the actions that would be
taken and their possible effects, this analysis assumes no such action. Further,
this  analysis  does not  consider  the  effects  of the  change in the level of
overall economic activity that could exist in such an environment.

ITEM 4. CONTROLS AND PROCEDURES

(a)  As of September  30, 2003,  an  evaluation  was carried out by  management,
     under the  supervision  and with the  participation  of our chief executive
     officer and chief  financial  officer,  of the  effectiveness  of Company's
     disclosure  controls and procedures.  Based on such  evaluation,  our chief
     executive  officer  and our  chief  financial  officer  concluded  that the
     disclosure  controls  and  procedures  are  effective  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, (1)
     is recorded,  processed,  summarized  and  reported  within the time period
     specified in the SEC's rules and forms and that the information required to
     be discussed by the Company in the reports that it files and submits  under
     the Securities Exchange Act of 1934, as amended, and (2) is accumulated and
     communicated  to the  Company's  management,  including  the  officers,  as
     appropriate to allow timely decisions regarding required disclosure.

(b)  There were no changes in the  Company's  internal  control  over  financial
     reporting  that  have  materially  affected,  or are  reasonably  likely to
     materially affect, the Company's internal control 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, 2002 (the "2002 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
the Company's our 2002 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 2003 and beyond  will be  achieved.
For a  discussion  of our  growth  strategies,  see the  "Growth  and  Expansion
Strategies" section of Item 1 to our 2002 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 34.9% 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 E.  O'Reilly,  Lawrence  P.  O'Reilly,  Ted F. Wise and Greg L.
Henslee.  One key person,  Lawrence P.  O'Reilly  retired  from his  operational
duties in February  2003,  but will continue to serve on the Board of Directors.
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 2002 Form 10-K and our Proxy
Statement on Schedule 14A for the 2003 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.
