NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

June 30, 2014

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of O'Reilly Automotive, Inc. and its subsidiaries (the "Company" or "O'Reilly") have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") 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 U.S. GAAP 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 three and six months ended June 30, 2014, are not necessarily indicative of the results that may be expected for the year ended December 31, 2014. 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, 2013.

NOTE 2 – FAIR VALUE MEASUREMENTS

The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company uses the income and market approaches to determine the fair value of its assets and liabilities. The three levels of the fair value hierarchy are set forth below:

• Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

• Level 2 – Inputs other than quoted prices in active markets included within Level 1 that are observable for the asset or liability, either directly or indirectly.

• Level 3 – Unobservable inputs for the asset or liability.

Non-financial assets and liabilities measured at fair value on a nonrecurring basis:

Certain long-lived non-financial assets and liabilities may be required to be measured at fair value on a nonrecurring basis in certain circumstances, including when there is evidence of impairment. These non-financial assets and liabilities may include assets acquired in a business combination or property and equipment that are determined to be impaired. As of June 30, 2014, and December 31, 2013, the Company did not have any non-financial assets or liabilities that had been measured at fair value subsequent to initial recognition.

Fair value of financial instruments:

The carrying amounts of the Company’s senior notes are included in “Long-term debt, less current portion” on the accompanying Condensed Consolidated Balance Sheets as of June 30, 2014, and December 31, 2013.

The table below identifies the estimated fair value of the Company’s senior notes, using the market approach. The fair values as of June 30, 2014, and December 31, 2013, were determined by reference to quoted market prices of the same or similar instruments (Level 2) (in thousands):

	June 30, 2014				December 31, 2013
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
4.875% Senior Notes due 2021	$	497,701	$	548,605	$	497,525	$	524,434
4.625% Senior Notes due 2021	$	299,624	$	324,387	$	299,598	$	310,141
3.800% Senior Notes due 2022	$	299,059	$	306,063	$	299,011	$	290,453
3.850% Senior Notes due 2023	$	299,978	$	306,593	$	299,976	$	289,362

The accompanying Condensed Consolidated Balance Sheets include other financial instruments, including cash and cash equivalents, accounts receivable, amounts receivable from vendors and accounts payable. Due to the short-term nature of these financial instruments, the Company believes that the carrying values of these instruments approximate their fair values.

Unsecured revolving credit facility:

In January of 2011, and as amended in September of 2011 and July of 2013, the Company entered into a credit agreement (the "Credit Agreement") for a five-year $600 million unsecured revolving credit facility (the "Revolving Credit Facility") arranged by Bank of America, N.A., which is scheduled to mature in July of 2018. The Credit Agreement includes a $200 million sub-limit for the issuance of letters of credit and a $75 million sub-limit for swing line borrowings under the Revolving Credit Facility. As described in the Credit Agreement governing the Revolving Credit Facility, the Company may, from time to time, subject to certain conditions, increase the aggregate commitments under the Revolving Credit Facility by up to $200 million. As of June 30, 2014, and December 31, 2013, the Company had outstanding letters of credit, primarily to support obligations related to workers’ compensation, general liability and other insurance policies, in the amount of $47.8 million and $51.7 million, respectively, reducing the aggregate availability under the Revolving Credit Facility by those amounts. As of June 30, 2014, and December 31, 2013, the Company had no outstanding borrowings under the Revolving Credit Facility.

Borrowings under the Revolving Credit Facility (other than swing line loans) bear interest, at the Company’s option, at the Base Rate or Eurodollar Rate (both as defined in the Credit Agreement) plus an applicable margin. Swing line loans made under the Revolving Credit Facility bear interest at the Base Rate plus the applicable margin for Base Rate loans. In addition, the Company pays a facility fee on the aggregate amount of the commitments in an amount equal to a percentage of such commitments. The interest rate margins and facility fee are based upon the better of the ratings assigned to the Company’s debt by Moody’s Investor Service, Inc. and Standard & Poor’s Rating Services, subject to limited exceptions. As of June 30, 2014, based upon the Company's credit ratings, its margin for Base Rate loans was 0.000%, its margin for Eurodollar Rate loans was 0.975% and its facility fee was 0.150%.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.25 times through December 31, 2014, and 2.50 times thereafter through maturity, and a maximum consolidated leverage ratio of 3.00 times through maturity. The consolidated leverage ratio includes a calculation of adjusted debt to earnings before interest, taxes, depreciation, amortization, rent and stock-based compensation expense. Adjusted debt includes outstanding debt, outstanding stand-by letters of credit and similar instruments, six-times rent expense and excludes any premium or discount recorded in conjunction with the issuance of long-term debt. In the event that the Company should default on any covenant contained within the Credit Agreement, certain actions may be taken, including, but not limited to, possible termination of credit extensions, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from lenders.As of June 30, 2014, the Company remained in compliance with all covenants under the Credit Agreement.

Senior notes:

The Company has issued $1.4 billion aggregate principal amount of unsecured senior notes due between 2021 and 2023 with United Missouri Bank, N.A. ("UMB") as trustee. Interest on the unsecured notes of 3.800% to 4.875% is payable biannually and is computed on the basis of a 360-day year.

6

The senior notes are guaranteed on a senior unsecured basis by each of the Company’s subsidiaries (“Subsidiary Guarantors”) that incurs or guarantees the Company’s obligations under the Company’s Revolving Credit Facility or certain other debt of the Company or any of the Subsidiary Guarantors. The guarantees are joint and several and full and unconditional, subject to certain customary automatic release provisions, including release of the subsidiary guarantor’s guarantee under the Company’s Credit Agreement and certain other debt, or, in certain circumstances, the sale or other disposition of a majority of the voting power of the capital interest in, or of all or substantially all of the property of, the subsidiary guarantor.  Each of the Subsidiary Guarantors is 100% owned, directly or indirectly, by the Company and the Company has no independent assets or operations other than those of its subsidiaries. The only direct or indirect subsidiaries of the Company that would not be Subsidiary Guarantors would be minor subsidiaries. Neither the Company, nor any of its Subsidiary Guarantors, are subject to any material or significant restrictions on the Company’s ability to obtain funds from its subsidiaries by dividend or loan or to transfer assets from such subsidiaries, except as provided by applicable law. Each of the senior notes is subject to certain customary covenants, with which the Company complied as of June 30, 2014.

NOTE 4 – WARRANTIES

The Company provides warranties on certain merchandise it sells with warranty periods ranging from 30 days to limited lifetime warranties. The risk of loss arising from warranty claims is typically the obligation of the Company's vendors. Certain vendors provide upfront allowances to the Company in lieu of accepting the obligation for warranty claims. For this merchandise, when sold, the Company bears the risk of loss associated with the cost of warranty claims. Differences between vendor allowances received by the Company in lieu of warranty obligations and estimated warranty expense are recorded as an adjustment to cost of sales. Estimated warranty costs are based on the historical failure rate of each individual product line. The Company's historical experience has been that failure rates are relatively consistent over time and that the ultimate cost of warranty claims to the Company has been driven by volume of units sold as opposed to fluctuations in failure rates or the variation of the cost of individual claims. The Company's product warranty liabilities are included in “Other current liabilities” on the accompanying Condensed Consolidated Balance Sheets as of June 30, 2014, and December 31, 2013.

The following table identifies the changes in the Company’s aggregate product warranty liabilities for the six months ended June 30, 2014 (in thousands):

Balance at December 31, 2013	$	33,386
Warranty claims	(25,057		)
Warranty accruals	27,691
Balance at June 30, 2014	$	36,020

NOTE 5 – SHARE REPURCHASE PROGRAM

Under the Company's share repurchase program, as approved by the Board of Directors, the Company may, from time to time, repurchase shares of its common stock, solely through open market purchases effected through a broker dealer at prevailing market prices, based on a variety of factors such as price, corporate trading policy requirements and overall market conditions. The Company and its Board of Directors may increase or otherwise modify, renew, suspend or terminate the share repurchase program at any time, without prior notice. As announced on February 5, 2014, the Company's Board of Directors approved a resolution to increase the cumulative authorization amount by an additional $500 million, raising the cumulative authorization under the share repurchase program to $4.0 billion. The additional $500 million authorization is effective for a three-year period, which began on February 5, 2014.

The following table identifies shares of the Company’s common stock that have been repurchased as part of the Company’s publicly announced share repurchase program (in thousands, except per share data):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2014		2013		2014		2013
Shares repurchased	1,873		2,546		2,022		5,013
Average price per share	$	148.21	$	107.61	$	148.21	$	100.10
Total investment	$	277,561	$	273,946	$	299,625	$	501,838

As of June 30, 2014, the Company had $346.1 million remaining under its share repurchase program. Subsequent to the end of the second quarter and through August 8, 2014, the Company repurchased an additional 1.2 million shares of its common stock under its share repurchase program, at an average price of $151.00, for a total investment of $177.8 million. The Company has repurchased a total of 43.8 million shares of its common stock under its share repurchase program since the inception of the program in January of 2011 and through August 8, 2014, at an average price of $87.47, for a total aggregate investment of $3.8 billion.

NOTE 6 – SHARE-BASED COMPENSATION

The Company recognizes share-based compensation expense based on the fair value of the grants, awards or shares at the time of the grant, award or issuance. Share-based compensation includes stock option awards issued under the Company’s employee incentive plans and director stock plan, restricted stock awarded under the Company’s employee incentive plans, performance incentive plan and director stock plan, stock issued through the Company’s employee stock purchase plan and stock awarded to employees through other benefit programs.

Stock options:

The Company’s stock-based incentive plans provide for the granting of stock options for the purchase of common stock of the Company to directors and certain key employees of the Company. Options are granted at an exercise price that is equal to the closing market price of the Company's common stock on the date of the grant. Director options granted under the plans expire after seven years and are fully vested after six months. Employee options granted under the plans expire after ten years and typically vest 25% per year, over four years. The Company records compensation expense for the grant date fair value of the option awards, adjusted for estimated forfeitures, evenly over the vesting period.

The table below identifies stock option activity under these plans during the six months ended June 30, 2014:

	Shares (in thousands)		Weighted-Average Exercise Price
Outstanding at December 31, 2013	5,227		$	54.11
Granted	261		140.78
Exercised	(683	)	43.53
Forfeited	(128	)	81.65
Outstanding at June 30, 2014	4,677		$	59.75
Exercisable at June 30, 2014	2,984		$	40.86

The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes option pricing model. The Black-Scholes model requires the use of assumptions, including the risk free rate, expected life, expected volatility and expected dividend yield.

• Risk-free interest rate – The United States Treasury rates in effect at the time the options are granted for the options’ expected life.

•

• Expected life - Represents the period of time that options granted are expected to be outstanding. The Company uses historical experience to estimate the expected life of options granted.

• Expected volatility – Measure of the amount by which the Company’s stock price has historically fluctuated.

• Expected dividend yield – The Company has not paid, nor does it have plans in the foreseeable future to pay, any dividends.

The table below identifies the weighted-average assumptions used for stock options awarded during the six months ended June 30, 2014 and 2013:

	For the Six Months Ended June 30,
	2014			2013
Risk free interest rate	1.65	%		0.85	%
Expected life	5.5		Years	5.2		Years
Expected volatility	25.2	%		32.3	%
Expected dividend yield	—	%		—	%

The Company’s forfeiture rate is the estimated percentage of options awarded that are expected to be forfeited or canceled prior to becoming fully vested. The Company’s estimate is evaluated periodically and is based upon historical experience at the time of evaluation and reduces expense ratably over the vesting period or the minimum required service period.

8

The following table summarizes activity related to stock options awarded by the Company for the three and six months ended June 30, 2014 and 2013 (in thousands):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2014		2013		2014		2013
Compensation expense for stock options awarded	$	5,710	$	4,580	$	9,794	$	9,237
Income tax benefit from compensation expense related to stock options	2,113		1,747		3,625		3,524

The weighted-average grant-date fair value of options granted during the six months ended June 30, 2014, was $37.63 compared to $29.54 for the six months ended June 30, 2013. The remaining unrecognized compensation expense related to unvested stock option awards at June 30, 2014, was $34.1 million and the weighted-average period of time over which this cost will be recognized is 2.5 years.

Other share-based compensation plans:

The Company sponsors other share-based compensation plans: an employee stock purchase plan (the “ESPP”), which permits all eligible employees to purchase shares of the Company’s common stock at 85% of the fair market value; a performance incentive plan, which provides for the award of shares of restricted stock to its corporate and senior management that vest evenly over a three-year period and are held in escrow until such vesting has occurred; and a director stock plan, which provides for the award of shares of restricted stock to the Company's independent directors that vest evenly over a three-year period and are held in escrow until such vesting has occurred. The fair value of shares awarded under these plans is based on the closing market price of the Company's common stock on the date of award, and compensation expense is recorded evenly over the vesting period.

⁽¹⁾  See Note 6 for further discussion on the terms of the Company's share-based compensation plans.

For the three and six months ended June 30, 2014 and 2013, the computation of diluted earnings per share did not include certain securities. These securities represent underlying stock options not included in the computation of diluted earnings per share, because the inclusion of such equity awards would have been antidilutive.

Subsequent to the end of the second quarter and through August 8, 2014, the Company repurchased 1.2 million shares of its common stock, at an average price of $151.00, for a total investment of $177.8 million.

NOTE 8 – LEGAL MATTERS

O’Reilly is currently involved in litigation incidental to the ordinary conduct of the Company’s business. The Company records reserves for litigation losses in instances where a material adverse outcome is probable and the Company is able to reasonably estimate the probable loss. The Company reserves for an estimate of material legal costs to be incurred in pending litigation matters. Although the Company cannot ascertain the amount of liability that it may incur from any of these matters, it does not currently believe that, in the aggregate, these matters, taking into account applicable insurance and reserves, will have a material adverse effect on its consolidated financial position, results of operations or cash flows in a particular quarter or annual period.

In addition, O’Reilly was involved in resolving governmental investigations that were being conducted against CSK Auto Corporation ("CSK") and CSK’s former officers and other litigation, prior to its acquisition by O’Reilly in 2008, as described below.

As previously reported, the governmental investigations of CSK regarding its legacy pre-acquisition accounting practices have concluded. All criminal charges against former employees of CSK related to its legacy pre-acquisition accounting practices, as well as the civil litigation filed against CSK’s former Chief Executive Officer by the Securities and Exchange Commission (the "SEC"), have concluded.

Under Delaware law, the charter documents of the CSK entities, and certain indemnification agreements, CSK may have certain indemnification obligations. As a result of the CSK acquisition, O’Reilly has incurred legal fees and costs related to these potential indemnification obligations arising from the litigation commenced by the Department of Justice and SEC against CSK’s former employees. Whether those legal fees and costs are covered by CSK’s insurance is subject to uncertainty, and, given its complexity and scope, the final outcome cannot be predicted at this time. O’Reilly has a remaining reserve, with respect to the indemnification obligations of $13.4

10

million at June 30, 2014, which relates to the payment of those legal fees and costs already incurred. It is possible that in a particular quarter or annual period the Company’s results of operations and cash flows could be materially affected by resolution of such matter, depending, in part, upon the results of operations or cash flows for such period. However, at this time, management believes that the ultimate outcome of this matter, after consideration of applicable reserves, should not have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

NOTE 9 - RECENT ACCOUNTING PRONOUNCEMENTS

In May of 2014, the Financial Accounting Standards Board issued Accounting Standard Update No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). Under ASU 2014-09, an entity is required to follow a five-step process to determine the amount of revenue to recognize when promised goods or services are transferred to customers. ASU 2014-09 offers specific accounting guidance for costs to obtain or fulfill a contract with a customer. In addition, an entity is required to disclose sufficient information to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and can be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2017; the Company is in the process of evaluating the potential future impact, if any, of ASU 2014-09 on its consolidated financial position, results of operations and cash flows.

OVERVIEW

We are a specialty retailer of automotive aftermarket parts, tools, supplies, equipment and accessories in the United States. We are one of the largest U.S. automotive aftermarket specialty retailers, selling our products to both do-it-yourself (“DIY”) customers and professional service providers – our “dual market strategy.” Our stores carry an extensive product line consisting of new and remanufactured automotive hard parts, maintenance items, accessories, a complete line of auto body paint and related materials, automotive tools and professional service provider service equipment. Our extensive product line includes an assortment of products that are differentiated by quality and price for most of the product lines we offer. For many of our product offerings, this quality differentiation reflects “good,” “better,” and “best” alternatives. Our sales and total gross margin dollars are highest for the “best” quality category of products. Consumers’ willingness to select products at a higher point on the value spectrum is a driver of sales and profitability in our industry. Our stores also offer enhanced services and programs to our customers: used oil, oil filter and battery recycling; battery, wiper and bulb replacement; battery diagnostic testing; electrical and module testing; check engine light code extraction; loaner tool program; drum and rotor resurfacing; custom hydraulic hoses; professional paint shop mixing and related materials; and machine shops.

Our strategy is to open new stores to achieve greater penetration into existing markets and expansion into new, contiguous markets. We plan to open 200 net, new stores in 2014. We typically open new stores either by (i) constructing a new facility or renovating an existing one on property we purchase or lease and stocking the new store with fixtures and inventory; (ii) acquiring an independently owned auto parts store, typically by the purchase of substantially all of the inventory and other assets (other than realty) of such store; or (iii) purchasing multi-store chains. We believe our investment in store growth will be funded with the cash flows expected to be generated by our existing operations and through available borrowings under our existing credit facility. During the three months ended June 30, 2014, we opened 42 stores and closed one store. During the six months ended June 30, 2014, we opened 93 stores and closed two stores and, as of that date, operated 4,257 stores in 42 states.

12

Operating within the retail industry, we are influenced by a number of general macroeconomic factors including, but not limited to, fuel costs, unemployment rates, consumer preferences and spending habits, and competition. The difficult conditions that affected the overall macroeconomic environment in recent years continue to impact O’Reilly and the retail sector in general. We believe that the average consumer’s tendency has been to “trade down” to lower quality products during challenging macroeconomic conditions. We have ongoing initiatives aimed at tailoring our product offering to adjust to customers’ changing preferences; however, we also continue to have initiatives focused on marketing and training to educate customers on the advantages of “purchasing up” on the value spectrum.

We believe the key drivers of current and future demand of the products sold within the automotive aftermarket include the number of U.S. miles driven, number of U.S. registered vehicles, new light vehicle registrations, average vehicle age and unemployment.

• Number of Miles Driven - The number of total miles driven in the U.S. influences the demand for repair and maintenance products sold within the automotive aftermarket. According to the Department of Transportation, prior to 2007, the annual number of total miles driven in the U.S. had steadily increased; however, since that time, as the U.S. experienced difficult macroeconomic conditions and historically high levels of unemployment, the number of total miles driven in the U.S. have remained relatively flat. Although total miles driven have not significantly increased since 2007, vehicles in the U.S. continue to be driven approximately three trillion miles per year, resulting in ongoing wear and tear and continued demand for the repair and maintenance products sold within the automotive aftermarket. In addition, we believe that as the U.S. economy continues to recover and the level of unemployment declines, total miles driven in the U.S. will return to a period of annual growth, supporting continued demand for automotive aftermarket products.

• Number of U.S. Registered Vehicles, New Light Vehicle Registrations and Average Vehicle Age - The total number of vehicles on the road and the average age of the vehicle population heavily influence the demand for products sold within the automotive aftermarket industry. As reported by the Automotive Aftermarket Industry Association (“AAIA”), the total number of registered vehicles has increased 6% over the past decade, from 235 million light vehicles in 2003 to 249 million light vehicles in 2013. Annual new light vehicle registrations have increased in recent years, reaching 15.4 million registered vehicles in 2013, up from 10.4 million registrations in 2009 and the seasonally adjusted annual rate (the "SAAR") of sales of light vehicles in the U.S. increased to approximately 17 million as of June 30, 2014, contributing to the growth in the total number of registered vehicles on the road. In addition, during the past decade, vehicle scrappage rates remained relatively stable, ranging from just 5.2% to 5.7% annually. The stable scrappage rates over the past decade have contributed to an increase in the average age of the U.S. vehicle population over that period, growing 16%, from 9.7 years in 2003 to 11.3 years in 2013. We believe this increase in average age can be attributed to better engineered and manufactured vehicles, which can be reliably driven at higher mileages due to better quality power trains and interiors and exteriors, and the consumer’s willingness to invest in maintaining these higher-mileage, better built vehicles. As the average age of the vehicle on the road increases, a larger percentage of miles are being driven by vehicles which are outside of a manufacturer warranty. These out-of-warranty, older vehicles generate strong demand for automotive aftermarket products as they go through more routine maintenance cycles, have more frequent mechanical failures and generally require more maintenance than newer vehicles. As the U.S. economy recovers, we believe consumers will continue to invest in these reliable, higher-quality, higher-mileage vehicles and these investments, along with an increasing total light vehicle fleet, will support continued demand for automotive aftermarket products.

• Unemployment - Unemployment, underemployment, the threat of future joblessness and the continued uncertainty surrounding the overall economic health of the U.S. have had a negative impact on consumer confidence and the level of consumer discretionary spending. Long-term trends of high unemployment could continue to impede the growth of annual miles driven, as well as decrease consumer discretionary spending, both of which negatively impact demand for products sold in the automotive aftermarket industry. However, as of June 30, 2014, the U.S. unemployment rate decreased to 6.1%, its lowest rate in over five years. We believe that as the economy continues to recover, total employment should increase and we would expect to see a corresponding increase in commuter traffic as unemployed individuals return to work. Aided by the anticipated increase in commuter miles, we believe overall annual U.S. miles driven should return to a period of annual growth, resulting in continued demand for automotive aftermarket products.

We remain confident in our ability to gain market share in our existing markets and grow our business in new markets by focusing on our dual market strategy and the core O’Reilly values of hard work and excellent customer service.

RESULTS OF OPERATIONS

Sales:

Sales for the three months ended June 30, 2014, increased $132 million to $1.85 billion from $1.71 billion for the same period one year ago, representing an increase of 8%. Sales for the six months ended June 30, 2014, increased $275 million to $3.58 billion from $3.30 billion for the same period one year ago, representing an increase of 8%. Comparable store sales for stores open at least one year increased 5.1% and 6.5% for the three months ended June 30, 2014 and 2013, respectively. Comparable store sales for stores open at least one year increased 5.7% and 3.6% for the six months ended June 30, 2014 and 2013, respectively. Comparable store sales are calculated

13

based on the change in sales of stores open at least one year and exclude sales of specialty machinery, sales to independent parts stores and sales to Team Members.

The following table presents the components of the increase in sales for the three and six months ended June 30, 2014 (in millions):

	Increase in Sales for the Three Months Ended June 30, 2014, Compared to the Same Period in 2013			Increase in Sales for the Six Months Ended June 30, 2014, Compared to the Same Period in 2013
Store sales:
Comparable store sales	$	86		$	184
Non-comparable store sales:
Sales for stores opened throughout 2013, excluding stores open at least one year that are included in comparable store sales	31			70
Sales in 2013 for stores that have closed	(1		)	(2		)
Sales for stores opened throughout 2014	14			20
Non-store sales:
Includes sales of machinery and sales to independent parts stores and Team Members	2			3
Total increase in sales	$	132		$	275

We believe our increased sales are the result of store growth and the high levels of customer service provided by our well-trained and technically proficient Team Members, superior inventory availability, enhanced services and programs offered in most stores, a broader selection of product offerings in most stores with a dynamic catalog system to identify and source parts, a targeted promotional and advertising effort through a variety of media and localized promotional events, continued improvement in the merchandising and store layouts of our stores, compensation programs for all store Team Members that provide incentives for performance and our continued focus on serving both DIY and professional service provider customers.

Our comparable store sales increase for the three months and six months ended June 30, 2014, was driven by an increase in average ticket values, for both DIY and professional business, and an increase in customer transaction counts for the professional business, partially offset by a slightly negative DIY customer transaction counts for the three months ended June 30, 2014. The improvements in average ticket values were the result of the continued growth of the more costly, hard part categories as a percentage of our total sales. The overall growth in the hard part categories continues to be driven by the increasing cost of replacement parts necessary to maintain the current population of better engineered and more technically advanced vehicles. The increase in professional service provider customer transaction counts was primarily driven by our acquired markets and the continued growth of less mature stores. Both DIY and professional service provider customer transaction counts continue to be negatively impacted by better engineered and more technically advanced vehicles, which have been manufactured in recent years. These vehicles require less frequent repairs and the component parts are more durable and last for longer periods of time; however, when repairs are required, the cost of the replacement parts is, on average, greater.

We opened 41 and 91 net, new stores during the three and six months ended June 30, 2014, respectively, compared to 46 and 111 net, new stores for the three and six months ended June 30, 2013, respectively. As of June 30, 2014, we operated 4,257 stores in 42 states compared to 4,087 stores in 42 states at June 30, 2013. We anticipate total new store growth to be 200 net, new stores in 2014.

Gross profit:

Gross profit for the three months ended June 30, 2014, increased to $951 million (or 51.5% of sales) from $872 million (or 50.8% of sales) for the same period one year ago, representing an increase of 9%. Gross profit for the six months ended June 30, 2014, increased to $1.83 billion (or 51.1% of sales) from $1.67 billion (or 50.6% of sales) for the same period one year ago, representing an increase of 9%. The increase in gross profit dollars for the three and six months ended June 30, 2014, was primarily a result of the increase in comparable store sales at existing stores and sales from new stores. The increase in gross profit as a percentage of sales for the three and six months ended June 30, 2014, was primarily due to acquisition cost improvements, partially offset by the non-cash LIFO impact resulting from continued product acquisition cost reductions. Acquisition cost improvements are the result of our ongoing negotiations with our vendors to improve our inventory purchase costs. As previously discussed, during the third quarter of 2013, we depleted our LIFO reserve due to acquisition cost improvements we realized over time. Our policy is to not write up inventory in excess of replacement cost and, accordingly, we are effectively valuing our inventory at replacement cost. During the three and six months ended June 30, 2014, our LIFO cost was written down by approximately $4 million and $27 million, respectively, to reflect replacement cost. For the remainder of the year ending December 31, 2014, we do anticipate additional product acquisition cost reductions based on current negotiations with vendors, which, if finalized, could create additional LIFO gross margin headwinds.

14

Selling, general and administrative expenses:

Selling, general and administrative expenses (“SG&A”) for the three months ended June 30, 2014, increased to $614 million (or 33.3% of sales) from $576 million (or 33.6% of sales) for the same period one year ago, representing an increase of 7%. SG&A for the six months ended June 30, 2014, increased to $1.20 billion (or 33.7% of sales) from $1.12 billion (or 34.0% of sales) for the same period one year ago, representing an increase of 7%. The increase in total SG&A dollars for the three and six months ended June 30, 2014, were primarily the result of additional Team Members, facilities and vehicles to support our increased store count. The decrease in SG&A as a percentage of sales for the three and six months ended June 30, 2014, were primarily the result of increased leverage of store occupancy costs on strong comparable store sales results.

Operating income:

As a result of the impacts discussed above, operating income for the three months ended June 30, 2014, increased to $336 million (or 18.2% of sales) from $296 million (or 17.3% of sales) for the same period one year ago, representing an increase of 14%. Operating income for the six months ended June 30, 2014, increased to $624 million (or 17.4% of sales) from $547 million (or 16.6% of sales) for the same period one year ago, representing an increase of 14%.

Other income and expense:

Total other expense for the three months ended June 30, 2014, increased to $12 million (or 0.6% of sales), from $10 million (or 0.6% of sales) for the same period one year ago, representing an increase of 15%. Total other expense for the six months ended June 30, 2014, increased to $24 million (or 0.7% of sales) from $21 million (or 0.6% of sales) for the same period one year ago, representing an increase of 16%. The increase in total other expense was primarily the result of increased interest expense on higher average outstanding borrowings.

Income taxes:

Our provision for income taxes for the three months ended June 30, 2014, increased to $119 million (or 6.5% of sales) from $109 million (or 6.4% of sales) for the same period one year ago, representing an increase of 9%. Our provision for income taxes for the six months ended June 30, 2014, increased to $220 million (or 6.2% of sales) from $195 million (or 5.9% of sales) for the same period one year ago, representing an increase of 13%. Our effective tax rate for the three months ended June 30, 2014, was 36.7% of income before income taxes compared to 38.1% for the same period one year ago. Our effective tax rate for the six months ended June 30, 2014, was 36.7% of income before income taxes compare to 37.1% for the same period one year ago. The increase in our provision for income taxes for the three and six months ended June 30, 2014, were primarily the result of higher taxable income in the current period driven by our strong operating results. The decrease in our effective tax rate for the three and six months ended June 30, 2014, was primarily due to an increased benefit from employment tax credits in the current period.

Net income:

As a result of the impacts discussed above, net income for the three months ended June 30, 2014, increased to $206 million (or 11.1% of sales), from $177 million (or 10.3% of sales) for the same period one year ago, representing an increase of 16%. As a result of the impacts discussed above, net income for the six months ended June 30, 2014, increased to $380 million (or 10.6% of sales) from $331 million (or 10.0% of sales) for the same period one year ago, representing an increase of 14%.

Earnings per share:

Our diluted earnings per common share for the three months ended June 30, 2014, increased 21% to $1.91 on 108 million shares from $1.58 on 112 million shares for the same period one year ago. Our diluted earnings per common share for the six months ended June 30, 2014, increased 20% to $3.52 on 108 million shares versus $2.94 for the same period one year ago on 113 million shares.

LIQUIDITY AND CAPITAL RESOURCES

Our long-term business strategy requires capital to open new stores, fund strategic acquisitions, expand distribution infrastructure, operate and maintain existing stores and may include the opportunistic repurchase of shares of our common stock through our Board-approved share repurchase program. The primary sources of our liquidity are funds generated from operations and borrowed under our unsecured revolving credit facility. Decreased demand for our products or changes in customer buying patterns could negatively impact our ability to generate funds from operations. Additionally, decreased demand or changes in buying patterns could impact our ability to meet the debt covenants of our credit agreement and, therefore, negatively impact the funds available under our unsecured revolving credit facility. We believe that cash expected to be provided by operating activities and availability under our unsecured revolving credit facility will be sufficient to fund both our short-term and long-term capital and liquidity needs for the foreseeable future. However, there can be no assurance that we will continue to generate cash flows at or above recent levels.

15

The following table identifies cash provided by/(used in) our operating, investing and financing activities for the six months ended June 30, 2014 and 2013 (in thousands):

	For the Six Months Ended June 30,
Liquidity	2014			2013
Total cash provided by (used in):
Operating activities	$	655,525		$	439,412
Investing activities	(192,305		)	(173,733		)
Financing activities	(241,107		)	(147,877		)
Increase in cash and cash equivalents	$	222,113		$	117,802
Capital expenditures	$	194,929		$	176,577
Free cash flow (1)	460,596			262,835

⁽¹⁾  Calculated as net cash provided by operating activities, less capital expenditures for the period.

Operating activities:

The increase in net cash provided by operating activities during the six months ended June 30, 2014, compared to the same period in 2013, was primarily due to increases in net income, accounts payable and accrued payroll related liabilities and a decrease in cash used in accounts receivable. The increase in accounts payable during the period, as compared to the same period in the prior year, was driven by an increased level of inventory purchases during the current period, resulting from our strong sales performance and the timing of payments. The increase in accrued liabilities during the period, as compared to the same period in the prior year, was due to the timing of pay period end dates versus check dates. The decrease in cash used in accounts receivable during the period, as compared to the same period in the prior year, was due to the timing of period ending dates. During the prior year, the period ended on a weekend, and as such we did not process payments on accounts, resulting in a temporary increase in our accounts receivable balances in the prior period.

Investing activities:

The increase in net cash used in investing activities during the six months ended June 30, 2014, compared to the same period in 2013, was primarily the result of an increase in capital expenditures during the current period related to the construction of distribution facilities to support our ongoing store growth.

Financing activities:

The increase in net cash used in financing activities during the six months ended June 30, 2014, compared to the same period in 2013, was primarily attributable to the net proceeds from the issuance of long-term debt in the prior period, offset by the impact of fewer repurchases of our common stock during the current period under our share repurchase program.

Unsecured revolving credit facility:

In January of 2011, and as amended in September of 2011 and July of 2013, we entered into a credit agreement (the "Credit Agreement") for a five-year $600 million unsecured revolving credit facility (the "Revolving Credit Facility") arranged by Bank of America, N.A., which is scheduled to mature in July of 2018. The Credit Agreement includes a $200 million sub-limit for the issuance of letters of credit and a $75 million sub-limit for swing line borrowings under the Revolving Credit Facility. As described in the Credit Agreement governing the Revolving Credit Facility, we may, from time to time subject to certain conditions, increase the aggregate commitments under the Revolving Credit Facility by up to $200 million. As of June 30, 2014, we had outstanding letters of credit, primarily to support obligations related to workers’ compensation, general liability and other insurance policies, in the amount of $48 million, reducing the aggregate availability under the Revolving Credit Facility by that amount. As of June 30, 2014, we had no outstanding borrowings under the Revolving Credit Facility.

Senior Notes:

We have issued $1.4 billion aggregate principal amount of unsecured senior notes due between 2021 and 2023 with United Missouri Bank, N.A. ("UMB") as trustee. Interest on the unsecured senior notes of 3.800% to 4.875% is payable biannually and is computed on the basis of a 360-day year.

The senior notes are guaranteed on a senior unsecured basis by each of our subsidiaries (“Subsidiary Guarantors”) that incurs or guarantees our obligations under our Revolving Credit Facility or certain of our other debt or any of our Subsidiary Guarantors. The guarantees are joint and several and full and unconditional, subject to certain customary automatic release provisions, including release of the subsidiary guarantor’s guarantee under our Credit Agreement and certain other debt, or, in certain circumstances, the sale or other disposition of a majority of the voting power of the capital interest in, or of all or substantially all the property of, the subsidiary guarantor.  Each of the

16

Subsidiary Guarantors is 100% owned, directly or indirectly, by us and we have no independent assets or operations other than those of our subsidiaries. Our only direct or indirect subsidiaries that would not be Subsidiary Guarantors would be minor subsidiaries. Neither we, nor any of our Subsidiary Guarantors, are subject to any material or significant restrictions on our ability to obtain funds from our subsidiaries by dividend or loan or to transfer assets from such subsidiaries, except as provided by applicable law. Each of our senior notes is subject to certain customary covenants, with which we complied as of June 30, 2014.

Debt covenants:

The indentures governing our senior notes contain covenants that limit our ability and the ability of certain of our subsidiaries to, among other things: (i) create certain liens on assets to secure certain debt; (ii) enter into certain sale and leaseback transactions; and (iii) merge or consolidate with another company or transfer all or substantially all of our or its property, in each case as set forth in the indentures. These covenants are, however, subject to a number of important limitations and exceptions.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.25 times through December 31, 2014, and 2.50 times thereafter through maturity, and a maximum consolidated leverage ratio of 3.00 times through maturity. The consolidated leverage ratio includes a calculation of adjusted debt to earnings before interest, taxes, depreciation, amortization, rent and stock-based compensation expense (“EBITDAR”). Adjusted debt includes outstanding debt, outstanding stand-by letters of credit and similar instruments, six-times rent expense and excludes any premium or discount recorded in conjunction with the issuance of long-term debt. In the event that we should default on any covenant contained within the Credit Agreement, certain actions may be taken, including, but not limited to, possible termination of credit extensions, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from our lenders. We had a consolidated fixed charge coverage ratio of 5.13 times and 4.93 times as of June 30, 2014 and 2013, respectively, and a consolidated leverage ratio of 1.81 times and 1.98 times as of June 30, 2014 and 2013, respectively, remaining in compliance with all covenants related to the borrowing arrangements. Under our current financing plan, we have targeted an adjusted debt to adjusted EBITDAR ratio range of 2.00 times to 2.25 times.

The table below outlines the calculations of the consolidated fixed charge coverage ratio and consolidated leverage ratio covenants, as defined in the Credit Agreement governing the Revolving Credit Facility, for the twelve months ended June 30, 2014 and 2013 (dollars in thousands):

	For the Twelve Months Ended June 30,
	2014			2013
GAAP net income	$	718,343		$	623,590
Add: Interest expense	52,435			44,796

The consolidated fixed charge coverage ratio and consolidated leverage ratio discussed and presented in the table above are not derived in accordance with United States generally accepted accounting principles ("GAAP"). We do not, nor do we suggest investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, GAAP financial information. We believe that the presentation of our consolidated fixed charge coverage ratio and consolidated leverage ratio and free cash flow provides meaningful supplemental information to both management and investors that reflects the required covenants under our credit agreement. We include these items in judging our performance and believe this non-GAAP information is useful to investors as well. Material limitations of these non-GAAP measures are that such measures do not reflect actual GAAP amounts. We compensate for such limitations by presenting, in the tables above, a reconciliation to the most directly comparable GAAP measures.

Share repurchase program:

Under our share repurchase program, as approved by our Board of Directors, we may, from time to time, repurchase shares of our common stock, solely through open market purchases effected through a broker dealer at prevailing market prices, based on a variety of factors such as price, corporate trading policy requirements and overall market conditions. We may increase or otherwise modify, renew, suspend or terminate the share repurchase program at any time, without prior notice. As announced on February 5, 2014, our Board of Directors approved a resolution to increase the cumulative authorization amount by an additional $500 million, raising the cumulative authorization under the share repurchase program to $4.0 billion. The additional $500 million authorization is effective for a three-year period, which began on February 5, 2014.

The following table identifies shares of our common stock that have been repurchased as part of our publicly announced share repurchase program (in thousands, except per share data):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2014		2013		2014		2013
Shares repurchased	1,873		2,546		2,022		5,013
Average price per share	$	148.21	$	107.61	$	148.21	$	100.10
Total investment	$	277,561	$	273,946	$	299,625	$	501,838

As of June 30, 2014, we had $346 million remaining under our share repurchase program. Subsequent to the end of the second quarter and through August 8, 2014, we repurchased an additional 1.2 million shares of our common stock under our share repurchase program, at an average price of $151.00, for a total investment of $178 million. We have repurchased a total of 43.8 million shares of our common stock under our share repurchase program since the inception of the program in January of 2011 and through August 8, 2014, at an average price of $87.47, for a total aggregate investment of $3.8 billion.

CONTRACTUAL OBLIGATIONS

There have been no material changes to the contractual obligations to which we are committed since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2013.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our financial statements in accordance with U.S. GAAP requires the application of certain estimates and judgments by management. Management bases its assumptions, estimates, and adjustments on historical experience, current trends and other factors believed to be relevant at the time the condensed consolidated financial statements are prepared. There have been no material changes in the critical accounting estimates since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2013.

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. To the extent our acquisition cost increased due to base commodity price increases industry-wide, we have typically been able to pass along these increased costs through higher retail prices for the affected products. As a result, we do not believe inflation has had a material adverse effect on our operations.

To some extent, our business is seasonal primarily as a result of the impact of weather conditions on customer buying patterns. While we have historically realized operating profits in each quarter of the year, our store sales and profits have historically been higher in the second and third quarters (April through September) than in the first and fourth quarters (October through March) of the year.

RECENT ACCOUNTING PRONOUNCEMENTS

In May of 2014, the Financial Accounting Standards Board issued Accounting Standard No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). Under ASU 2014-09, an entity is required to follow a five-step process to determine the amount of revenue to recognize when promised goods or services are transferred to customers. ASU 2014-09 offers specific accounting guidance for costs to obtain or fulfill a contract with a customer. In addition, an entity is required to disclose sufficient information to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and can be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. We will adopt this guidance beginning with our first quarter ending March 31, 2017; we are in the process of evaluating the potential future impact, if any, of ASU 2014-09 on our consolidated financial position, results of operations and cash flows.

INTERNET ADDRESS AND ACCESS TO SEC FILINGS

Our Internet address is www.oreillyauto.com. Interested readers can access, free of charge, our 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's website at www.sec.gov and searching with our ticker symbol "ORLY." Such reports are generally available the day they are filed. Upon request, we will furnish interested readers a paper copy of such reports free of charge.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to interest rate risk to the extent we borrow against our unsecured revolving credit facility (the “Revolving Credit Facility”) with variable interest rates based on either a Base Rate or Eurodollar Rate, as defined in the credit agreement governing the Revolving Credit Facility. As of June 30, 2014, we had no outstanding borrowings under our Revolving Credit Facility.

We invest certain of our excess cash balances in short-term, highly-liquid instruments with maturities of 90 days or less. We do not expect any material losses from our invested cash balances and we believe that our interest rate exposure is minimal. As of June 30, 2014, our cash and cash equivalents totaled $453 million.

Our market risks have not materially changed since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2013.

Item 4. Controls and Procedures

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) and as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (“the Exchange Act”). Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are functioning effectively to provide reasonable assurance that the information required to be disclosed by us (including our consolidated subsidiaries) in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

CHANGES IN INTERNAL CONTROLS

There were no changes in our internal control over financial reporting during the fiscal quarter ending June 30, 2014, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

O’Reilly is currently involved in litigation incidental to the ordinary conduct of the Company’s business. The Company records reserves for litigation losses in instances where a material adverse outcome is probable and the Company is able to reasonably estimate the probable loss. The Company reserves for an estimate of material legal costs to be incurred in pending litigation matters. Although the Company cannot ascertain the amount of liability that it may incur from any of these matters, it does not currently believe that, in the aggregate, these matters, taking into account applicable insurance and reserves, will have a material adverse effect on its consolidated financial position, results of operations or cash flows in a particular quarter or annual period.

In addition, O’Reilly was involved in resolving governmental investigations that were being conducted against CSK Auto Corporation ("CSK") and CSK’s former officers and other litigation, prior to its acquisition by O’Reilly in 2008, as described below.

As previously reported, the governmental investigations of CSK regarding its legacy pre-acquisition accounting practices have concluded. All criminal charges against former employees of CSK related to its legacy pre-acquisition accounting practices, as well as the civil litigation filed against CSK’s former Chief Executive Officer by the Securities and Exchange Commission (the “SEC”), have concluded.

Under Delaware law, the charter documents of the CSK entities and certain indemnification agreements, CSK may have certain indemnification obligations. As a result of the CSK acquisition, O’Reilly has incurred legal fees and costs related to these potential indemnification obligations arising from the litigation commenced by the Department of Justice and SEC against CSK’s former employees. Whether those legal fees and costs are covered by CSK’s insurance is subject to uncertainty, and, given its complexity and scope, the final outcome cannot be predicted at this time. O’Reilly has a remaining reserve, with respect to the indemnification obligations of $13 million at June 30, 2014, which relates to the payment of those legal fees and costs already incurred. It is possible that in a particular quarter or annual period the Company’s results of operations and cash flows could be materially affected by resolution of such matter, depending, in part, upon the results of operations or cash flows for such period. However, at this time, management believes that the ultimate outcome of this matter, after consideration of applicable reserves, should not have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

Item 1A. Risk Factors

As of June 30, 2014, there have been no material changes in our risk factors since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2013.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

There were no sales of unregistered securities during the three or six months ended June 30, 2014. The following table identifies all repurchases during the three months ended June 30, 2014, of any of our securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, by or on behalf of us or any affiliated purchaser (in thousands, except per share amounts):

Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Programs	Maximum Dollar Value of Shares that May Yet Be Purchased Under the Programs(1)
April 1, 2014, to April 30, 2014	278	$	144.96	278	$	583,443

Total as of June 30, 2014	1,873	$	148.21	1,873

⁽¹⁾  Under our share repurchase program, as approved by our Board of Directors, we may, from time to time, repurchase shares of our common stock, solely through open market purchases effected through a broker dealer at prevailing market prices, based on a variety of factors such as price, corporate trading policy requirements and overall market conditions. We may increase or otherwise modify, renew, suspend or terminate the share repurchase program at any time, without prior notice. As announced on February 5, 2014, our Board of Directors approved a resolution to increase the authorization under the share repurchase program by an additional $500 million, raising the cumulative authorization amount under the share repurchase program to $4.0 billion. The additional $500 million authorization is effective for a three-year period, which began on February 5, 2014. The current authorization under the share repurchase program is scheduled to expire on February 5, 2017. No other share repurchase programs existed during the three or six months ended June 30, 2014.

Subsequent to the end of the second quarter and through August 8, 2014, we repurchased an additional 1.2 million shares of our common stock under our share repurchase program, at an average price of $151.00, for a total investment of $178 million. We have repurchased

20

a total of 43.8 million shares of our common stock under our share repurchase program since the inception of the program in January of 2011 and through August 8, 2014, at an average price of $87.47, for a total aggregate investment of $3.8 billion.

Warranties

NOTE 4 – WARRANTIES

The Company provides warranties on certain merchandise it sells with warranty periods ranging from 30 days to limited lifetime warranties. The risk of loss arising from warranty claims is typically the obligation of the Company's vendors. Certain vendors provide upfront allowances to the Company in lieu of accepting the obligation for warranty claims. For this merchandise, when sold, the Company bears the risk of loss associated with the cost of warranty claims. Differences between vendor allowances received by the Company in lieu of warranty obligations and estimated warranty expense are recorded as an adjustment to cost of sales. Estimated warranty costs are based on the historical failure rate of each individual product line. The Company's historical experience has been that failure rates are relatively consistent over time and that the ultimate cost of warranty claims to the Company has been driven by volume of units sold as opposed to fluctuations in failure rates or the variation of the cost of individual claims. The Company's product warranty liabilities are included in “Other current liabilities” on the accompanying Condensed Consolidated Balance Sheets as of June 30, 2014, and December 31, 2013.

The following table identifies the changes in the Company’s aggregate product warranty liabilities for the six months ended June 30, 2014 (in thousands):

Unsecured revolving credit facility:

In January of 2011, and as amended in September of 2011 and July of 2013, the Company entered into a credit agreement (the "Credit Agreement") for a five-year $600 million unsecured revolving credit facility (the "Revolving Credit Facility") arranged by Bank of America, N.A., which is scheduled to mature in July of 2018. The Credit Agreement includes a $200 million sub-limit for the issuance of letters of credit and a $75 million sub-limit for swing line borrowings under the Revolving Credit Facility. As described in the Credit Agreement governing the Revolving Credit Facility, the Company may, from time to time, subject to certain conditions, increase the aggregate commitments under the Revolving Credit Facility by up to $200 million. As of June 30, 2014, and December 31, 2013, the Company had outstanding letters of credit, primarily to support obligations related to workers’ compensation, general liability and other insurance policies, in the amount of $47.8 million and $51.7 million, respectively, reducing the aggregate availability under the Revolving Credit Facility by those amounts. As of June 30, 2014, and December 31, 2013, the Company had no outstanding borrowings under the Revolving Credit Facility.

Borrowings under the Revolving Credit Facility (other than swing line loans) bear interest, at the Company’s option, at the Base Rate or Eurodollar Rate (both as defined in the Credit Agreement) plus an applicable margin. Swing line loans made under the Revolving Credit Facility bear interest at the Base Rate plus the applicable margin for Base Rate loans. In addition, the Company pays a facility fee on the aggregate amount of the commitments in an amount equal to a percentage of such commitments. The interest rate margins and facility fee are based upon the better of the ratings assigned to the Company’s debt by Moody’s Investor Service, Inc. and Standard & Poor’s Rating Services, subject to limited exceptions. As of June 30, 2014, based upon the Company's credit ratings, its margin for Base Rate loans was 0.000%, its margin for Eurodollar Rate loans was 0.975% and its facility fee was 0.150%.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.25 times through December 31, 2014, and 2.50 times thereafter through maturity, and a maximum consolidated leverage ratio of 3.00 times through maturity. The consolidated leverage ratio includes a calculation of adjusted debt to earnings before interest, taxes, depreciation, amortization, rent and stock-based compensation expense. Adjusted debt includes outstanding debt, outstanding stand-by letters of credit and similar instruments, six-times rent expense and excludes any premium or discount recorded in conjunction with the issuance of long-term debt. In the event that the Company should default on any covenant contained within the Credit Agreement, certain actions may be taken, including, but not limited to, possible termination of credit extensions, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from lenders.As of June 30, 2014, the Company remained in compliance with all covenants under the Credit Agreement.

Senior notes:

The Company has issued $1.4 billion aggregate principal amount of unsecured senior notes due between 2021 and 2023 with United Missouri Bank, N.A. ("UMB") as trustee. Interest on the unsecured notes of 3.800% to 4.875% is payable biannually and is computed on the basis of a 360-day year.

The senior notes are guaranteed on a senior unsecured basis by each of the Company’s subsidiaries (“Subsidiary Guarantors”) that incurs or guarantees the Company’s obligations under the Company’s Revolving Credit Facility or certain other debt of the Company or any of the Subsidiary Guarantors. The guarantees are joint and several and full and unconditional, subject to certain customary automatic release provisions, including release of the subsidiary guarantor’s guarantee under the Company’s Credit Agreement and certain other debt, or, in certain circumstances, the sale or other disposition of a majority of the voting power of the capital interest in, or of all or substantially all of the property of, the subsidiary guarantor.  Each of the Subsidiary Guarantors is 100% owned, directly or indirectly, by the Company and the Company has no independent assets or operations other than those of its subsidiaries. The only direct or indirect subsidiaries of the Company that would not be Subsidiary Guarantors would be minor subsidiaries. Neither the Company, nor any of its Subsidiary Guarantors, are subject to any material or significant restrictions on the Company’s ability to obtain funds from its subsidiaries by dividend or loan or to transfer assets from such subsidiaries, except as provided by applicable law. Each of the senior notes is subject to certain customary covenants, with which the Company complied as of June 30, 2014.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Abstract]

Fair value measurements

NOTE 2 – FAIR VALUE MEASUREMENTS

The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company uses the income and market approaches to determine the fair value of its assets and liabilities. The three levels of the fair value hierarchy are set forth below:

• Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

• Level 2 – Inputs other than quoted prices in active markets included within Level 1 that are observable for the asset or liability, either directly or indirectly.

• Level 3 – Unobservable inputs for the asset or liability.

Non-financial assets and liabilities measured at fair value on a nonrecurring basis:

Certain long-lived non-financial assets and liabilities may be required to be measured at fair value on a nonrecurring basis in certain circumstances, including when there is evidence of impairment. These non-financial assets and liabilities may include assets acquired in a business combination or property and equipment that are determined to be impaired. As of June 30, 2014, and December 31, 2013, the Company did not have any non-financial assets or liabilities that had been measured at fair value subsequent to initial recognition.

Fair value of financial instruments:

The carrying amounts of the Company’s senior notes are included in “Long-term debt, less current portion” on the accompanying Condensed Consolidated Balance Sheets as of June 30, 2014, and December 31, 2013.

The table below identifies the estimated fair value of the Company’s senior notes, using the market approach. The fair values as of June 30, 2014, and December 31, 2013, were determined by reference to quoted market prices of the same or similar instruments (Level 2) (in thousands):

For the three and six months ended June 30, 2014 and 2013, the computation of diluted earnings per share did not include certain securities. These securities represent underlying stock options not included in the computation of diluted earnings per share, because the inclusion of such equity awards would have been antidilutive.

Subsequent to the end of the second quarter and through August 8, 2014, the Company repurchased 1.2 million shares of its common stock, at an average price of $151.00, for a total investment of $177.8 million.

Share-Based Compensation

Employee Benefits and Share-based Compensation [Abstract]

Share-based compensation

NOTE 6 – SHARE-BASED COMPENSATION

The Company recognizes share-based compensation expense based on the fair value of the grants, awards or shares at the time of the grant, award or issuance. Share-based compensation includes stock option awards issued under the Company’s employee incentive plans and director stock plan, restricted stock awarded under the Company’s employee incentive plans, performance incentive plan and director stock plan, stock issued through the Company’s employee stock purchase plan and stock awarded to employees through other benefit programs.

Stock options:

The Company’s stock-based incentive plans provide for the granting of stock options for the purchase of common stock of the Company to directors and certain key employees of the Company. Options are granted at an exercise price that is equal to the closing market price of the Company's common stock on the date of the grant. Director options granted under the plans expire after seven years and are fully vested after six months. Employee options granted under the plans expire after ten years and typically vest 25% per year, over four years. The Company records compensation expense for the grant date fair value of the option awards, adjusted for estimated forfeitures, evenly over the vesting period.

The table below identifies stock option activity under these plans during the six months ended June 30, 2014:

	Shares (in thousands)		Weighted-Average Exercise Price
Outstanding at December 31, 2013	5,227		$	54.11
Granted	261		140.78
Exercised	(683	)	43.53
Forfeited	(128	)	81.65
Outstanding at June 30, 2014	4,677		$	59.75
Exercisable at June 30, 2014	2,984		$	40.86

The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes option pricing model. The Black-Scholes model requires the use of assumptions, including the risk free rate, expected life, expected volatility and expected dividend yield.

• Risk-free interest rate – The United States Treasury rates in effect at the time the options are granted for the options’ expected life.

•

• Expected life - Represents the period of time that options granted are expected to be outstanding. The Company uses historical experience to estimate the expected life of options granted.

• Expected volatility – Measure of the amount by which the Company’s stock price has historically fluctuated.

• Expected dividend yield – The Company has not paid, nor does it have plans in the foreseeable future to pay, any dividends.

The table below identifies the weighted-average assumptions used for stock options awarded during the six months ended June 30, 2014 and 2013:

	For the Six Months Ended June 30,
	2014			2013
Risk free interest rate	1.65	%		0.85	%
Expected life	5.5		Years	5.2		Years
Expected volatility	25.2	%		32.3	%
Expected dividend yield	—	%		—	%

The Company’s forfeiture rate is the estimated percentage of options awarded that are expected to be forfeited or canceled prior to becoming fully vested. The Company’s estimate is evaluated periodically and is based upon historical experience at the time of evaluation and reduces expense ratably over the vesting period or the minimum required service period.

The following table summarizes activity related to stock options awarded by the Company for the three and six months ended June 30, 2014 and 2013 (in thousands):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2014		2013		2014		2013
Compensation expense for stock options awarded	$	5,710	$	4,580	$	9,794	$	9,237
Income tax benefit from compensation expense related to stock options	2,113		1,747		3,625		3,524

The weighted-average grant-date fair value of options granted during the six months ended June 30, 2014, was $37.63 compared to $29.54 for the six months ended June 30, 2013. The remaining unrecognized compensation expense related to unvested stock option awards at June 30, 2014, was $34.1 million and the weighted-average period of time over which this cost will be recognized is 2.5 years.

Other share-based compensation plans:

The Company sponsors other share-based compensation plans: an employee stock purchase plan (the “ESPP”), which permits all eligible employees to purchase shares of the Company’s common stock at 85% of the fair market value; a performance incentive plan, which provides for the award of shares of restricted stock to its corporate and senior management that vest evenly over a three-year period and are held in escrow until such vesting has occurred; and a director stock plan, which provides for the award of shares of restricted stock to the Company's independent directors that vest evenly over a three-year period and are held in escrow until such vesting has occurred. The fair value of shares awarded under these plans is based on the closing market price of the Company's common stock on the date of award, and compensation expense is recorded evenly over the vesting period.

The table below summarizes activity related to the Company’s other share-based compensation and benefit plans for the three and six months ended June 30, 2014 and 2013 (in thousands):

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2014		2013		2014		2013
Compensation expense for shares issued under the ESPP	$	443	$	418	$	881	$	831

Fair value of financial instruments, policy

The Company uses the fair value hierarchy, which prioritizes the inputs used to measure the fair value of certain of its financial instruments. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The Company uses the income and market approaches to determine the fair value of its assets and liabilities.

Loss Contingency [Abstract]

Legal matters

NOTE 8 – LEGAL MATTERS

O’Reilly is currently involved in litigation incidental to the ordinary conduct of the Company’s business. The Company records reserves for litigation losses in instances where a material adverse outcome is probable and the Company is able to reasonably estimate the probable loss. The Company reserves for an estimate of material legal costs to be incurred in pending litigation matters. Although the Company cannot ascertain the amount of liability that it may incur from any of these matters, it does not currently believe that, in the aggregate, these matters, taking into account applicable insurance and reserves, will have a material adverse effect on its consolidated financial position, results of operations or cash flows in a particular quarter or annual period.

In addition, O’Reilly was involved in resolving governmental investigations that were being conducted against CSK Auto Corporation ("CSK") and CSK’s former officers and other litigation, prior to its acquisition by O’Reilly in 2008, as described below.

As previously reported, the governmental investigations of CSK regarding its legacy pre-acquisition accounting practices have concluded. All criminal charges against former employees of CSK related to its legacy pre-acquisition accounting practices, as well as the civil litigation filed against CSK’s former Chief Executive Officer by the Securities and Exchange Commission (the "SEC"), have concluded.

Under Delaware law, the charter documents of the CSK entities, and certain indemnification agreements, CSK may have certain indemnification obligations. As a result of the CSK acquisition, O’Reilly has incurred legal fees and costs related to these potential indemnification obligations arising from the litigation commenced by the Department of Justice and SEC against CSK’s former employees. Whether those legal fees and costs are covered by CSK’s insurance is subject to uncertainty, and, given its complexity and scope, the final outcome cannot be predicted at this time. O’Reilly has a remaining reserve, with respect to the indemnification obligations of $13.4 million at June 30, 2014, which relates to the payment of those legal fees and costs already incurred. It is possible that in a particular quarter or annual period the Company’s results of operations and cash flows could be materially affected by resolution of such matter, depending, in part, upon the results of operations or cash flows for such period. However, at this time, management believes that the ultimate outcome of this matter, after consideration of applicable reserves, should not have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

NOTE 9 - RECENT ACCOUNTING PRONOUNCEMENTS

In May of 2014, the Financial Accounting Standards Board issued Accounting Standard Update No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). Under ASU 2014-09, an entity is required to follow a five-step process to determine the amount of revenue to recognize when promised goods or services are transferred to customers. ASU 2014-09 offers specific accounting guidance for costs to obtain or fulfill a contract with a customer. In addition, an entity is required to disclose sufficient information to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and can be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2017; the Company is in the process of evaluating the potential future impact, if any, of ASU 2014-09 on its consolidated financial position, results of operations and cash flows.

Product Warranties Disclosures [Abstract]

Warranties, policy

The Company provides warranties on certain merchandise it sells with warranty periods ranging from 30 days to limited lifetime warranties. The risk of loss arising from warranty claims is typically the obligation of the Company's vendors. Certain vendors provide upfront allowances to the Company in lieu of accepting the obligation for warranty claims. For this merchandise, when sold, the Company bears the risk of loss associated with the cost of warranty claims. Differences between vendor allowances received by the Company in lieu of warranty obligations and estimated warranty expense are recorded as an adjustment to cost of sales. Estimated warranty costs are based on the historical failure rate of each individual product line. The Company's historical experience has been that failure rates are relatively consistent over time and that the ultimate cost of warranty claims to the Company has been driven by volume of units sold as opposed to fluctuations in failure rates or the variation of the cost of individual claims.

Under the Company's share repurchase program, as approved by the Board of Directors, the Company may, from time to time, repurchase shares of its common stock, solely through open market purchases effected through a broker dealer at prevailing market prices, based on a variety of factors such as price, corporate trading policy requirements and overall market conditions. The Company and its Board of Directors may increase or otherwise modify, renew, suspend or terminate the share repurchase program at any time, without prior notice. As announced on February 5, 2014, the Company's Board of Directors approved a resolution to increase the cumulative authorization amount by an additional $500 million, raising the cumulative authorization under the share repurchase program to $4.0 billion. The additional $500 million authorization is effective for a three-year period, which began on February 5, 2014.
