NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

September 30, 2015

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 nine months ended September 30, 2015, are not necessarily indicative of the results that may be expected for the year ended December 31, 2015. 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, 2014.

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.

Financial assets and liabilities measured at fair value on a recurring basis:

The carrying amount of the Company's marketable securities is included in "Other assets, net" on the accompanying Condensed Consolidated Balance Sheets as of September 30, 2015, and December 31, 2014. The Company recorded a decrease in fair value related to its marketable securities in the amounts of $1.1 million and $0.7 million, which was included in "Other income (expense)" on the accompanying Condensed Consolidated Statements of Income, for the three and nine months ended September 30, 2015, respectively.

The tables below identify the estimated fair value of the Company's marketable securities, determined by reference to quoted market prices (Level 1), as of September 30, 2015, and December 31, 2014 (in thousands):

	September 30, 2015
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Marketable securities	$	16,112	$	—	$	—	$	16,112

	December 31, 2014
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Marketable securities	$	15,378	$	—	$	—	$	15,378

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 September 30, 2015, and December 31, 2014, 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 September 30, 2015, and December 31, 2014. See Note 3 for further discussion on the Company's senior notes.

5

The table below identifies the estimated fair value of the Company's senior notes, using the market approach. The fair values as of September 30, 2015, and December 31, 2014, were determined by reference to quoted market prices of the same or similar instruments (Level 2) (in thousands):

	September 30, 2015				December 31, 2014
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
4.875% Senior Notes due 2021	$	498,140	$	550,638	$	497,876	$	566,700
4.625% Senior Notes due 2021	299,689		324,469		299,650		337,222
3.800% Senior Notes due 2022	299,186		307,285		299,109		310,749
3.850% Senior Notes due 2023	$	299,980	$	301,736	$	299,980	$	311,656

The accompanying Condensed Consolidated Balance Sheets include other financial instruments, including cash and cash equivalents, accounts receivable, amounts receivable from suppliers 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.

NOTE 3 – LONG-TERM DEBT

The following table identifies the amounts included in "Current portion of long-term debt" and "Long-term debt, less current portion" on the accompanying Condensed Consolidated Balance Sheets as of September 30, 2015, and December 31, 2014 (in thousands):

Unsecured revolving credit facility:

On January 14, 2011, the Company entered into a credit agreement, as amended by Amendment No. 1 dated as of September 9, 2011, and as further amended by Amendment No. 2 dated as of July 2, 2013, and by Amendment No. 3 dated as of June 18, 2015 (the "Credit Agreement"). The Credit Agreement provides for a $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 September 30, 2015, and December 31, 2014, the Company had outstanding letters of credit, primarily to support obligations related to workers' compensation, general liability and other insurance policies, in the amounts of $45.9 million and $47.9 million, respectively, reducing the aggregate availability under the Revolving Credit Facility by those amounts. As of September 30, 2015, and December 31, 2014, 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

6

Ratings Services, subject to limited exceptions. As of September 30, 2015, based upon the Company's credit ratings, its margin for Base Rate loans was 0.000%, its margin for Eurodollar Rate loans was 0.875% and its facility fee was 0.125%.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.50 times 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 non-cash share-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 commitments, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from lenders.As of September 30, 2015, 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 January of 2021 and June of 2023 with United Missouri Bank, N.A. as trustee. Interest on the senior notes, ranging from 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 obligations under the Company's Credit Agreement or under other credit facility or capital markets debt of the Company's or any of the Company's 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, is 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 September 30, 2015.

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 suppliers. Certain suppliers 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 supplier 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, which are recorded as obligations at the time of sale, 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 September 30, 2015, and December 31, 2014. The following table identifies the changes in the Company's aggregate product warranty liabilities for the nine months ended September 30, 2015 (in thousands):

Warranty liabilities, balance at December 31, 2014	$	34,226
Warranty claims	(45,712		)
Warranty accruals	45,375
Warranty liabilities, balance at September 30, 2015	$	33,889

NOTE 5 – SHARE REPURCHASE PROGRAM

In January of 2011, the Company's Board of Directors approved a share repurchase program. Under the program, 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's 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 4, 2015, and May 29, 2015, the Company's Board of Directors each time approved a resolution to increase the authorization amount under the share repurchase program by an additional $500 million, resulting in a

7

cumulative authorization amount of $5.5 billion. Each additional $500 million authorization is effective for a three-year period, beginning on its respective announcement date.

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   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Shares repurchased	1,147		2,542		3,784		4,564
Average price per share	$	238.97	$	152.42	$	224.39	$	150.55
Total investment	$	274,213	$	387,461	$	849,145	$	687,086

As of September 30, 2015, the Company had $430.2 million remaining under its share repurchase program. Subsequent to the end of the third quarter and through November 6, 2015, the Company repurchased an additional 0.1 million shares of its common stock under its share repurchase program, at an average price of $249.06, for a total investment of $32.3 million. The Company has repurchased a total of 50.3 million shares of its common stock under its share repurchase program since the inception of the program in January of 2011 and through November 6, 2015, at an average price of $101.51, for a total aggregate investment of $5.1 billion.

NOTE 6 – SHARE-BASED COMPENSATION AND BENEFIT PLANS

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 minimum required service period.

The table below identifies stock option activity under these plans during the nine months ended September 30, 2015 (in thousands, except per share data):

	Shares		Weighted-Average Exercise Price
Outstanding at December 31, 2014	4,065		$	64.57

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 grants awarded during the nine months ended September 30, 2015 and 2014:

	For the Nine Months Ended   September 30,
	2015		2014
Risk free interest rate	1.54	%	1.60	%
Expected life	5.8 Years		5.3 Years
Expected volatility	22.3	%	25.0	%
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 nine months ended September 30, 2015 and 2014 (in thousands):

	For the Three Months Ended   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Compensation expense for stock options awarded	$	4,409	$	4,184	$	13,916	$	13,978
Income tax benefit from compensation expense related to stock options	1,657		1,548		5,198		5,173

The weighted-average grant-date fair value of options granted during the nine months ended September 30, 2015, was $51.59 compared to $36.86 for the nine months ended September 30, 2014. The remaining unrecognized compensation expense related to unvested stock option awards at September 30, 2015, was $27.9 million and the weighted-average period of time over which this cost will be recognized is 2.6 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 issued under the ESPP is based on the average of the high and low market prices of the Company's common stock during the offering periods, and compensation expense is recognized based on the discount between the fair value and the employee purchase price for the shares sold to employees. The fair value of shares awarded under restricted stock plans is based on the closing market price of the Company's common stock on the date of the award, and compensation expense is recorded evenly over the minimum required service period.

The table below summarizes activity related to the Company's other share-based compensation plans for the three and nine months ended September 30, 2015 and 2014 (in thousands):

	For the Three Months Ended   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Compensation expense for shares issued under the ESPP	$	526	$	451	$	1,513	$	1,332
Income tax benefit from compensation expense related to shares issued under the ESPP	198		167		565		493
Compensation expense for restricted shares awarded	417		652		1,227		2,114
Income tax benefit from compensation expense related to restricted awards	$	157	$	241	$	459	$	782

Profit sharing and savings plan:

The Company sponsors a contributory profit sharing and savings plan (the "401(k) Plan") that covers substantially all employees who are at least 21 years of age and have at least six months of service. The Company makes matching contributions equal to 100% of the first 2% of each employee's wages that are contributed and 25% of the next 4% of each employee's wages that are contributed. An employee must be employed on December 31 to receive that year's Company matching contribution, with the matching contribution funded annually in the January following the year in which the matching contribution was earned. The Company may also make additional discretionary profit sharing contributions to the plan on an annual basis as determined by the Board of Directors. The Company did not make any discretionary contributions to the 401(k) Plan during the three or nine months ended September 30, 2015 or 2014. The Company expensed matching contributions under the 401(k) Plan in the amounts of $4.8 million and $4.3 million for the three months ended September 30, 2015 and 2014, respectively. The Company expensed matching contributions under the 401(k) Plan in the amounts of $13.4 million and $12.5 million for the nine months ended September 30, 2015 and 2014, respectively.

Nonqualified deferred compensation plan:

The Company sponsors a nonqualified deferred compensation plan (the "Deferred Compensation Plan") for highly compensated employees whose contributions to the 401(k) Plan are limited due to the application of the annual limitations under the Internal Revenue Code. The Deferred Compensation Plan provides these employees with the opportunity to defer compensation, including salary and incentive based compensation, that was precluded under the Company's 401(k) Plan due to the annual limitations, which is then matched by the Company using the same formula as the 401(k) Plan. An employee must be employed on December 31 to receive that year's Company matching contribution, with the matching contribution funded annually in the January following the year in which the matching contribution was earned. In the event of bankruptcy, the assets of this plan are available to satisfy the claims of general creditors. The Company has an unsecured obligation to pay, in the future, the value of the deferred compensation and Company match adjusted to reflect the performance, whether positive or negative, of selected investment measurement options chosen by each participant during the deferral period. The liability for compensation deferred under the Deferred Compensation Plan was $16.1 million and $15.4 million as of September 30, 2015, and December 31, 2014, respectively, and was included within "Other liabilities" on the Condensed Consolidated Balance Sheets. The Company expensed matching contributions under the Deferred Compensation Plan in the amount of less than $0.1 million for each of the three months ended September 30, 2015 and 2014. The Company expensed matching contributions under the Deferred Compensation Plan in the amounts of $0.1 million and $0.2 million for the nine months ended September 30, 2015 and 2014, respectively.

NOTE 7 – EARNINGS PER SHARE

The following table illustrates the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2015 and 2014 (in thousands, except per share data):

	For the Three Months Ended   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Numerator (basic and diluted):

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

10

For the three and nine months ended September 30, 2015 and 2014, 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 third quarter and through November 6, 2015, the Company repurchased 0.1 million shares of its common stock, at an average price of $249.06, for a total investment of $32.3 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.

As previously reported, the Company received a subpoena from the District Attorney of the County of Alameda, along with other environmental prosecutorial offices in the state of California, seeking documents and information related to the handling, storage and disposal of hazardous waste. Management has an ongoing and open dialogue with these agencies regarding this matter and is cooperating fully with the request; however, at this time a prediction of the ultimate outcome of these efforts cannot be determined.

As previously reported, on June 18, 2015, a jury in Greene County, Missouri returned an unfavorable verdict in a litigated contract dispute in the matter Meridian Creative Alliance vs. O'Reilly Automotive Stores, Inc, et. al. in the amount of $12.5 million. The Company strongly believes that the verdict was unjust and unsupported by the law and the underlying facts and, further, that there are several potential bases for reversal on appeal. The Company intends to vigorously challenge the verdict in the Court of Appeals. The Company currently has reserved $18.8 million with respect to this matter.

NOTE 9 - RECENT ACCOUNTING PRONOUNCEMENTS

In May of 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standard Update ("ASU") 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. In August of 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" ("ASU 2015-14"), to defer the effective date of ASU 2014-09 by one year. Originally, for public companies, ASU 2014-09 was effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and could be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. For public companies, ASU 2015-14 changes ASU 2014-09 to be effective for annual reporting periods beginning after December 15, 2017, including periods within that reporting period, and can be adopted retrospectively or as a cumulative effective adjustment at the date of adoption, with early adoption allowed, but not before ASU 2014-09's original effective date of December 15, 2016. The Company will adopt this guidance beginning with its first quarter ending March 31, 2018. 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.

In January of 2015, the FASB issued ASU No. 2015-01, "Extraordinary and Unusual Items (Subtopic 225-20)" ("ASU 2015-01"). ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items; such that, an entity will no longer need to assess whether a particular event or transaction event is extraordinary. ASU 2015-01 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, and early adoption is permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2016. The application of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

In April of 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30)" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. In August of 2015, the FASB issued ASU 2015-15, "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, EITF Meeting" ("ASU 2015-15"), to update ASU 2015-03 to reflect a Securities and Exchange Commission change. ASU 2015-15 allows an entity, in the case of a line-of-credit arrangement, to either follow ASU 2015-03 or defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratable over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, including

11

periods within that reporting period, requires retrospective application, and early adoption is permitted. The Company will adopt this guidance with its first quarter ending March 31, 2016. The application of this guidance affects classification only, and therefore, it is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cashflows.

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, including 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 205 net, new stores in 2015, and 210 net, new stores in 2016. 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 unsecured revolving credit facility. During the three months ended September 30, 2015, we opened 59 stores and closed one store. During the nine months ended September 30, 2015, we opened 160 stores and closed three stores and, as of that date, operated 4,523 stores in 43 states.

13

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. During challenging macroeconomic conditions, we believe that the average consumer's tendency has been to defer maintenance on their vehicles or "trade down" to lower quality products. 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 ongoing vehicle maintenance, as well as "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, between 2008 and 2013, as the U.S. experienced difficult macroeconomic conditions and historically high levels of unemployment, the number of total miles driven in the U.S. remained relatively flat. In 2014, as the U.S. economy began to recover, miles driven also improved increasing 1.7%, and through August of 2015, year-to-date miles driven increased 3.4%. We believe that as the U.S. economy continues to recover and the level of unemployment continues to decline, total miles driven in the U.S. will continue to increase and return to the historical trend of long-term annual growth. In total, 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.

• 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 Auto Care Association, the total number of registered vehicles increased 6% from 2004 to 2014, bringing the number of light vehicles on the road to 253 million by the end of 2014. For the year ended December 31, 2014, the seasonally adjusted annual rate of light vehicle sales in the U.S. ("SAAR") was approximately 17 million, and for 2015, the SAAR is estimated to be approximately 18 million, contributing to the continued growth in the total number of registered vehicles on the road. In the past decade, vehicle scrappage rates have remained relatively stable, ranging from 4.6% to 5.7% annually. Over the past decade, the average age of the U.S. vehicle population has increased, growing 21%, from 9.4 years in 2004 to 11.4 years in 2014. 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 that 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. 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 uncertainty surrounding the overall economic health of the U.S. have a negative impact on consumer confidence and the level of consumer discretionary spending. Long-term trends of high unemployment could 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. As of December 31, 2014, the U.S. unemployment rate was 5.6%, and as of September 30, 2015, the U.S. unemployment rate decreased to 5.1%, its lowest rate in over seven years. We believe that as the economy continues to recover, total employment should continue to 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 long-term 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 September 30, 2015, increased $203 million to $2.08 billion from $1.88 billion for the same period one year ago, representing an increase of 11%. Sales for the nine months ended September 30, 2015, increased $566 million to $6.02 billion from $5.45 billion for the same period one year ago, representing an increase of 10%. Comparable store sales for stores open at least one year increased 7.9% and 6.2% for the three months ended September 30, 2015 and 2014, respectively. Comparable store sales for stores open at least one year increased 7.4% and 5.9% for the nine months ended September 30, 2015 and 2014, respectively. Comparable store sales are calculated 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.

14

The following table presents the components of the increase in sales for the three and nine months ended September 30, 2015 (in millions):

	Increase in Sales for the Three Months Ended September 30, 2015, Compared to the Same Period in 2014			Increase in Sales for the Nine Months Ended September 30, 2015, Compared to the Same Period in 2014
Store sales:
Comparable store sales	$	145		$	397
Non-comparable store sales:
Sales for stores opened throughout 2014, excluding stores open at least one year that are included in comparable store sales	26			109
Sales for stores opened throughout 2015	32			59
Sales in 2014 for stores that have closed	(2		)	(5		)
Non-store sales:
Includes sales of machinery and sales to independent parts stores and Team Members	2			6
Total increase in sales	$	203		$	566

We believe the increased sales achieved by our stores 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, including same day and over-night access to inventory in our regional distribution centers, enhanced services and programs offered in our 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 increases for the three and nine months ended September 30, 2015, were driven by increases in average ticket values and customer transaction counts for both our DIY and professional service provider customers. 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 of our hard part categories continues to be driven by our faster growing professional service provider sales, which are primarily comprised of hard parts categories, and the increasing complexity and cost of replacement parts necessary to maintain the current population of better engineered and more technically advanced vehicles. These better engineered vehicles require less frequent repairs, as the component parts are more durable and last for longer periods of time, creating pressure on customer transaction counts; however, when repairs are required, the cost of replacement parts is, on average, greater. While the less frequent repairs required by these better engineered vehicles does create pressure on customer transaction counts, during the three and nine months ended September 30, 2015, both our DIY and professional service provider customers transaction counts increased, driven by lower gas prices and decreasing unemployment levels, which led to increased miles driven and a corresponding increase in vehicle maintenance. These factors created a positive macroeconomic environment, which was beneficial to both DIY and professional service provider customer transaction counts. In addition, our continued focus on staffing our stores with knowledgeable parts professionals to assist our DIY customers during high DIY traffic periods, including nights and weekends, contributed to the increases in our DIY transaction counts, and increases in professional service provider customer transaction counts benefited from the continued growth of our less mature stores.

We opened 58 and 157 net, new stores during the three and nine months ended September 30, 2015, respectively, compared to 54 and 145 net, new stores for the three and nine months ended September 30, 2014, respectively. As of September 30, 2015, we operated 4,523 stores in 43 states compared to 4,311 stores in 43 states at September 30, 2014. We anticipate total new store growth to be 205 net, new store openings in 2015, and 210 net, new store openings in 2016.

Gross profit:

Gross profit for the three months ended September 30, 2015, increased to $1.09 billion (or 52.4% of sales) from $968 million (or 51.6% of sales) for the same period one year ago, representing an increase of 13%. Gross profit for the nine months ended September 30, 2015, increased to $3.14 billion (or 52.1% of sales) from $2.80 billion (or 51.3% of sales) for the same period one year ago, representing an increase of 12%. The increases in gross profit dollars for the three and nine months ended September 30, 2015, were the result of the increase in comparable store sales at existing stores and sales from new stores. The increases in gross profit as a percentage of sales for the three and nine months ended September 30, 2015, were primarily due to product acquisition cost improvements and a smaller non-cash negative last-in, last-out ("LIFO") impact, as compared to the same periods in the prior year. Acquisition cost improvements are the result of our ongoing negotiations with our suppliers to improve our inventory purchase costs based on our increasing scale. The

15

non-cash negative LIFO impact is the result of our continued product acquisition cost reductions, and due to these acquisition cost reductions, we fully depleted our LIFO reserve in 2013. 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 months ended September 30, 2015 and 2014, our LIFO costs were written down by approximately $5 million and $6 million, respectively, to reflect replacement cost. During the nine months ended September 30, 2015 and 2014, our LIFO costs were written down by approximately $24 million and $34 million, respectively, to reflect replacement costs.

Selling, general and administrative expenses:

Selling, general and administrative expenses ("SG&A") for the three months ended September 30, 2015, increased to $674 million (or 32.4% of sales) from $624 million (or 33.3% of sales) for the same period one year ago, representing an increase of 8%. SG&A for the nine months ended September 30, 2015, increased to $1.98 billion (or 33.0% of sales) from $1.83 billion (or 33.6% of sales) for the same period one year ago, representing an increase of 8%. The increase in total SG&A dollars for the three months ended September 30, 2015, was primarily the result of additional Team Members, facilities and vehicles to support our increased store count. The increase in total SG&A dollars for the nine months ended September 30, 2015, was primarily the result of additional Team Members, facilities and vehicles to support our increased store count, and a $19 million litigation loss charge during our second quarter resulting from an adverse verdict in a contract dispute with a former service provider. The decreases in SG&A as a percentage of sales for the three and nine months ended September 30, 2015, were primarily due to increased leverage of store operating costs on strong comparable store sales results.

Operating income:

As a result of the impacts discussed above, operating income for the three months ended September 30, 2015, increased to $415 million (or 20.0% of sales) from $344 million (or 18.3% of sales) for the same period one year ago, representing an increase of 21%. As a result of the impacts discussed above, operating income for the nine months ended September 30, 2015, increased to $1.15 billion (or 19.1% of sales) from $967 million (or 17.7% of sales) for the same period one year ago, representing an increase of 19%.

Other income and expense:

Total other expense for the three months ended September 30, 2015, increased to $14 million (or 0.7% of sales) from $11 million (or 0.6% of sales) for the same period one year ago, representing an increase of 26%. Total other expense for the nine months ended September 30, 2015, increased to $41 million (or 0.7% of sales) from $35 million (or 0.6% of sales) for the same period one year ago, representing an increase of 15%. The increase in total other expense for the three months ended September 30, 2015, was primarily the result of a decrease in the amount of capitalized interest in the current period, as compared to the same period in the prior year, and a decrease in the value of our trading securities. The increase in total other expense for the nine months ended September 30, 2015, was primarily the result of a decrease in the amount of capitalized interest in the current period, as compared to the same period in the prior year.

Income taxes:

Our provision for income taxes for the three months ended September 30, 2015, increased to $135 million (or 6.5% of sales) from $115 million (or 6.1% of sales) for the same period one year ago, representing an increase of 17%. Our provision for income taxes for the nine months ended September 30, 2015, increased to $398 million (or 6.6% of sales) from $336 million (or 6.2% of sales) for the same period one year ago, representing an increase of 19%. Our effective tax rate for the three months ended September 30, 2015, was 33.6% of income before income taxes compared to 34.7% for the same period one year ago. Our effective tax rate for the nine months ended September 30, 2015, was 35.8% of income before income taxes compared to 36.0% for the same period one year ago. The increases in our provision for income taxes for the three and nine months ended September 30, 2015, were primarily the result of higher taxable income in the current periods, driven by our strong operating results, partially offset by lower effective tax rates. The decrease in our effective tax rate for the three months ended September 30, 2015, was primarily due to a greater amount of favorable resolutions of historical tax matters in the current period, as compared to the same period in the prior year. The decrease in our effective tax rate for the nine months ended September 30, 2015, was primarily due to a greater amount of favorable resolutions of historical tax matters in the current period, as compared to the same period in the prior year, partially offset by reduced benefits from employment tax credits in the current period, as compared to the same period in the prior year.

Net income:

As a result of the impacts discussed above, net income for the three months ended September 30, 2015, increased to $266 million (or 12.8% of sales) from $217 million (or 11.6% of sales) for the same period one year ago, representing an increase of 23%. As a result of the impacts discussed above, net income for the nine months ended September 30, 2015, increased to $713 million (or 11.8% of sales) from $597 million (or 10.9% of sales) for the same period one year ago, representing an increase of 19%.

16

Earnings per share:

Our diluted earnings per common share for the three months ended September 30, 2015, increased 28% to $2.64 on 101 million shares from $2.06 on 105 million shares for the same period one year ago. Our diluted earnings per common share for the nine months ended September 30, 2015, increased 25% to $6.98 on 102 million shares from $5.58 on 107 million shares for the same period one year ago.

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.

The following table identifies cash provided by/(used in) our operating, investing and financing activities for the nine months ended September 30, 2015 and 2014 (in thousands):

	For the Nine Months Ended   September 30,
Liquidity:	2015			2014
Total cash provided by (used in):
Operating activities	$	1,062,722		$	982,954
Investing activities	(291,249		)	(312,083		)
Financing activities	(745,117		)	(603,906		)
Increase in cash and cash equivalents	$	26,356		$	66,965
Capital expenditures	$	296,474		$	317,157
Free cash flow (1)	766,248			665,797

⁽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 nine months ended September 30, 2015, compared to the same period in 2014, was primarily due to the increase in net income, partially offset by the smaller decrease in net inventory investment. Net inventory investment reflects our investment in inventory, net of the amount of accounts payable to suppliers. The smaller increase in our net inventory investment is the result of fewer new suppliers entering our supplier financing programs in the current period, as compared to the same period in the prior year.

Investing activities:

The decrease in net cash used in investing activities during the nine months ended September 30, 2015, compared to the same period in 2014, was primarily the result of a decrease in capital expenditures. The decrease in capital expenditures was primarily related to the timing of property acquisitions, closings and construction costs for new stores during the current period, as compared to the same period in the prior year.

Financing activities:

The increase in net cash used in financing activities during the nine months ended September 30, 2015, compared to the same period in 2014, was primarily attributable to a higher level of repurchases of our common stock during the current period, as compared to the same period in the prior year.

Unsecured revolving credit facility:

On January 14, 2011, we entered into a credit agreement, as amended by Amendment No. 1 dated as of September 9, 2011, and as further amended by Amendment No. 2 dated as of July 2, 2013, and by Amendment No. 3 dated as of June 18, 2015 (the "Credit Agreement"). The Credit Agreement provides for a $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. As described in the Credit Agreement governing the Revolving

17

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 September 30, 2015, we had outstanding letters of credit, primarily to support obligations related to workers' compensation, general liability and other insurance policies, in the amount of $46 million, reducing the aggregate availability under the Revolving Credit Facility by that amount. As of September 30, 2015, we had no outstanding borrowings under the Revolving Credit Facility.

Senior Notes:

We have issued $1.40 billion aggregate principal amount of unsecured senior notes due between January of 2021 and June of 2023 with United Missouri Bank, N.A. as trustee. Interest on the senior notes, ranging from 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 obligations under our Credit Agreement or under other credit facility or capital markets debt of ours 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 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.

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. As of September 30, 2015, we were in compliance with the covenants applicable to our senior notes.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.50 times 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 non-cash share-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 commitments, 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 5.84 times and 5.24 times as of September 30, 2015 and 2014, respectively, and a consolidated leverage ratio of 1.57 times and 1.77 times as of September 30, 2015 and 2014, respectively, remaining in compliance with all covenants related to the borrowing arrangements. Under our current financing plan, we have targeted an adjusted debt to EBITDAR ratio range of 2.00 times to 2.25 times.

18

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 September 30, 2015 and 2014 (dollars in thousands):

	For the Twelve Months Ended September 30,

Free cash flow, the consolidated fixed charge coverage ratio and consolidated leverage ratio discussed and presented in the tables 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 free cash flow, consolidated fixed charge coverage ratio and consolidated leverage ratio provides meaningful supplemental information to both management and investors and reflects the required covenants under the 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:

In January of 2011, our Board of Directors approved a share repurchase program. Under the program, 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. Our 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 4, 2015, and May 29, 2015, our Board of Directors each time approved a resolution to increase the authorization amount under our share repurchase program by an additional $500 million, resulting in a cumulative authorization amount of $5.50 billion. Each additional $500 million authorization is effective for a three-year period, beginning on its respective announcement date.

19

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   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Shares repurchased	1,147		2,542		3,784		4,564
Average price per share	$	238.97	$	152.42	$	224.39	$	150.55
Total investment	$	274,213	$	387,461	$	849,145	$	687,086

As of September 30, 2015, we had $430 million remaining under our share repurchase program. Subsequent to the end of the third quarter and through November 6, 2015, we repurchased an additional 0.1 million shares of our common stock under our share repurchase program, at an average price of $249.06, for a total investment of $32 million. We have repurchased a total of 50.3 million shares of our common stock under our share repurchase program since the inception of the program in January of 2011 and through November 6, 2015, at an average price of $101.51, for a total aggregate investment of $5.10 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, 2014.

CRITICAL ACCOUNTING ESTIMATES

The preparation of our financial statements in accordance with 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, 2014.

INFLATION AND SEASONALITY

We have been successful, in many cases, in reducing the effects of merchandise cost increases principally by taking advantage of supplier 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 (the "FASB") issued Accounting Standard Update ("ASU") 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. In August of 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" ("ASU 2015-14"), to defer the effective date of ASU 2014-09 by one year. Originally, for public companies, ASU 2014-09 was effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and could be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. For public companies, ASU 2015-14 changes ASU 2014-09 to be effective for annual reporting periods beginning after December 15, 2017, including periods within that reporting period, and can be adopted retrospectively or as a cumulative effective adjustment at the date of adoption, with early adoption allowed, but not before ASU 2014-09's original effective date of December 15, 2016. We will adopt this guidance beginning with our first quarter ending March 31, 2018. 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.

In January of 2015, the FASB issued ASU No. 2015-01, "Extraordinary and Unusual Items (Subtopic 225-20)" ("ASU 2015-01"). ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items; such that, an entity will no longer need to assess whether a

20

particular event or transaction event is extraordinary. ASU 2015-01 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, and early adoption is permitted. We will adopt this guidance beginning with our first quarter ending March 31, 2016. The application of this guidance is not expected to have a material impact on our consolidated financial condition, results of operations or cash flows.

In April of 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30)" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. In August of 2015, the FASB issued ASU 2015-15, "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, EITF Meeting" ("ASU 2015-15"), to update ASU 2015-03 to reflect a Securities and Exchange Commission change. ASU 2015-15 allows an entity, in the case of a line-of-credit arrangement, to either follow ASU 2015-03 or defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratable over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, requires retrospective application, and early adoption is permitted. We will adopt this guidance with our first quarter ending March 31, 2016. The application of this guidance affects classification only, and therefore, it isnot expected to have a material impact on our consolidated financial condition, results of operations or cash flows.

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 September 30, 2015, 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 September 30, 2015, our cash and cash equivalents totaled $277 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, 2014.

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 September 30, 2015, 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 Automotive, Inc. and its subsidiaries (the "Company" or "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.

As previously reported, the Company received a subpoena from the District Attorney of the County of Alameda, along with other environmental prosecutorial offices in the state of California, seeking documents and information related to the handling, storage and disposal of hazardous waste. Management has an ongoing and open dialogue with these agencies regarding this matter and is cooperating fully with the request; however, at this time a prediction of the ultimate outcome of these efforts cannot be determined.

As previously reported, on June 18, 2015, a jury in Greene County, Missouri returned an unfavorable verdict in a litigated contract dispute in the matter Meridian Creative Alliance vs. O'Reilly Automotive Stores, Inc, et. al. in the amount of $12.5 million. The Company strongly believes that the verdict was unjust and unsupported by the law and the underlying facts and, further, that there are several potential bases for reversal on appeal. The Company intends to vigorously challenge the Court of Appeals. The Company currently has reserved $18.8 million with respect to this matter.

Item 1A. Risk Factors

As of September 30, 2015, there have been no material changes in O'Reilly Automotive, Inc. and its subsidiaries' risk factors since those discussed in our Annual Report on Form 10-K for the year ended December 31, 2014.

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

O'Reilly Automotive, Inc. and its subsidiaries (the "Company") had no sales of unregistered securities during the nine months ended September 30, 2015. The following table identifies all repurchases during the three months ended September 30, 2015, of any of the Company's securities registered under Section 12 of the Securities Exchange Act of 1934, as amended, by or on behalf of the Company or any affiliated purchaser (in thousands, except per share data):

⁽¹⁾  Under the Company's share repurchase program, as approved by its 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's 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 4, 2015, and May 29, 2015, the Company's Board of Directors each time approved a resolution to increase the authorization amount under the share repurchase program by an additional $500 million, resulting in a cumulative authorization amount of $5.5 billion. Each additional $500 million authorization is effective for a three-year period, beginning on its respective announcement date. The authorization under the share repurchase program that currently has capacity is scheduled to expire on May 29, 2018. No other share repurchase programs existed during the nine months ended September 30, 2015.

Subsequent to the end of the third quarter and through November 6, 2015, the Company repurchased an additional 0.1 million shares of its common stock under our share repurchase program, at an average price of $249.06, for a total investment of $32 million. The Company has repurchased a total of 50.3 million shares of its common stock under its share repurchase program since the inception of the program in January of 2011 and through November 6, 2015, at an average price of $101.51, for a total aggregate investment of $5.1 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 suppliers. Certain suppliers 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 supplier 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, which are recorded as obligations at the time of sale, 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 September 30, 2015, and December 31, 2014. The following table identifies the changes in the Company's aggregate product warranty liabilities for the nine months ended September 30, 2015 (in thousands):

Unsecured revolving credit facility:

On January 14, 2011, the Company entered into a credit agreement, as amended by Amendment No. 1 dated as of September 9, 2011, and as further amended by Amendment No. 2 dated as of July 2, 2013, and by Amendment No. 3 dated as of June 18, 2015 (the "Credit Agreement"). The Credit Agreement provides for a $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 September 30, 2015, and December 31, 2014, the Company had outstanding letters of credit, primarily to support obligations related to workers' compensation, general liability and other insurance policies, in the amounts of $45.9 million and $47.9 million, respectively, reducing the aggregate availability under the Revolving Credit Facility by those amounts. As of September 30, 2015, and December 31, 2014, 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 Ratings Services, subject to limited exceptions. As of September 30, 2015, based upon the Company's credit ratings, its margin for Base Rate loans was 0.000%, its margin for Eurodollar Rate loans was 0.875% and its facility fee was 0.125%.

The Credit Agreement contains certain covenants, including limitations on indebtedness, a minimum consolidated fixed charge coverage ratio of 2.50 times 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 non-cash share-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 commitments, immediate payment of outstanding principal amounts plus accrued interest and other amounts payable under the Credit Agreement and litigation from lenders.As of September 30, 2015, 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 January of 2021 and June of 2023 with United Missouri Bank, N.A. as trustee. Interest on the senior notes, ranging from 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 obligations under the Company's Credit Agreement or under other credit facility or capital markets debt of the Company's or any of the Company's 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, is 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 September 30, 2015.

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.

Financial assets and liabilities measured at fair value on a recurring basis:

The carrying amount of the Company's marketable securities is included in "Other assets, net" on the accompanying Condensed Consolidated Balance Sheets as of September 30, 2015, and December 31, 2014. The Company recorded a decrease in fair value related to its marketable securities in the amounts of $1.1 million and $0.7 million, which was included in "Other income (expense)" on the accompanying Condensed Consolidated Statements of Income, for the three and nine months ended September 30, 2015, respectively.

The tables below identify the estimated fair value of the Company's marketable securities, determined by reference to quoted market prices (Level 1), as of September 30, 2015, and December 31, 2014 (in thousands):

	September 30, 2015
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Marketable securities	$	16,112	$	—	$	—	$	16,112

	December 31, 2014
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Marketable securities	$	15,378	$	—	$	—	$	15,378

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 September 30, 2015, and December 31, 2014, 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 September 30, 2015, and December 31, 2014. See Note 3 for further discussion on the Company's senior notes.

The table below identifies the estimated fair value of the Company's senior notes, using the market approach. The fair values as of September 30, 2015, and December 31, 2014, were determined by reference to quoted market prices of the same or similar instruments (Level 2) (in thousands):

	September 30, 2015				December 31, 2014
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
4.875% Senior Notes due 2021	$	498,140	$	550,638	$	497,876	$	566,700
4.625% Senior Notes due 2021	299,689		324,469		299,650		337,222
3.800% Senior Notes due 2022	299,186		307,285		299,109		310,749
3.850% Senior Notes due 2023	$	299,980	$	301,736	$	299,980	$	311,656

The accompanying Condensed Consolidated Balance Sheets include other financial instruments, including cash and cash equivalents, accounts receivable, amounts receivable from suppliers 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent accounting pronouncements, policy

In May of 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standard Update ("ASU") 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. In August of 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" ("ASU 2015-14"), to defer the effective date of ASU 2014-09 by one year. Originally, for public companies, ASU 2014-09 was effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and could be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. For public companies, ASU 2015-14 changes ASU 2014-09 to be effective for annual reporting periods beginning after December 15, 2017, including periods within that reporting period, and can be adopted retrospectively or as a cumulative effective adjustment at the date of adoption, with early adoption allowed, but not before ASU 2014-09's original effective date of December 15, 2016. The Company will adopt this guidance beginning with its first quarter ending March 31, 2018. 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.

In January of 2015, the FASB issued ASU No. 2015-01, "Extraordinary and Unusual Items (Subtopic 225-20)" ("ASU 2015-01"). ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items; such that, an entity will no longer need to assess whether a particular event or transaction event is extraordinary. ASU 2015-01 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, and early adoption is permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2016. The application of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

In April of 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30)" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. In August of 2015, the FASB issued ASU 2015-15, "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, EITF Meeting" ("ASU 2015-15"), to update ASU 2015-03 to reflect a Securities and Exchange Commission change. ASU 2015-15 allows an entity, in the case of a line-of-credit arrangement, to either follow ASU 2015-03 or defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratable over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, requires retrospective application, and early adoption is permitted. The Company will adopt this guidance with its first quarter ending March 31, 2016. The application of this guidance affects classification only, and therefore, it is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cashflows.

For the three and nine months ended September 30, 2015 and 2014, 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 third quarter and through November 6, 2015, the Company repurchased 0.1 million shares of its common stock, at an average price of $249.06, for a total investment of $32.3 million.

Share-based compensation and benefit plans

NOTE 6 – SHARE-BASED COMPENSATION AND BENEFIT PLANS

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 minimum required service period.

The table below identifies stock option activity under these plans during the nine months ended September 30, 2015 (in thousands, except per share data):

	Shares		Weighted-Average Exercise Price
Outstanding at December 31, 2014	4,065		$	64.57
Granted	299		208.47
Exercised	(847	)	52.89
Forfeited	(88	)	90.92
Outstanding at September 30, 2015	3,429		$	79.32
Exercisable at September 30, 2015	2,323		$	50.08

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 grants awarded during the nine months ended September 30, 2015 and 2014:

	For the Nine Months Ended   September 30,
	2015		2014
Risk free interest rate	1.54	%	1.60	%
Expected life	5.8 Years		5.3 Years
Expected volatility	22.3	%	25.0	%
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 nine months ended September 30, 2015 and 2014 (in thousands):

	For the Three Months Ended   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Compensation expense for stock options awarded	$	4,409	$	4,184	$	13,916	$	13,978
Income tax benefit from compensation expense related to stock options	1,657		1,548		5,198		5,173

The weighted-average grant-date fair value of options granted during the nine months ended September 30, 2015, was $51.59 compared to $36.86 for the nine months ended September 30, 2014. The remaining unrecognized compensation expense related to unvested stock option awards at September 30, 2015, was $27.9 million and the weighted-average period of time over which this cost will be recognized is 2.6 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 issued under the ESPP is based on the average of the high and low market prices of the Company's common stock during the offering periods, and compensation expense is recognized based on the discount between the fair value and the employee purchase price for the shares sold to employees. The fair value of shares awarded under restricted stock plans is based on the closing market price of the Company's common stock on the date of the award, and compensation expense is recorded evenly over the minimum required service period.

The table below summarizes activity related to the Company's other share-based compensation plans for the three and nine months ended September 30, 2015 and 2014 (in thousands):

	For the Three Months Ended   September 30,				For the Nine Months Ended   September 30,
	2015		2014		2015		2014
Compensation expense for shares issued under the ESPP	$	526	$	451	$	1,513	$	1,332

Income tax benefit from compensation expense related to restricted awards	$	157	$	241	$	459	$	782

Profit sharing and savings plan:

The Company sponsors a contributory profit sharing and savings plan (the "401(k) Plan") that covers substantially all employees who are at least 21 years of age and have at least six months of service. The Company makes matching contributions equal to 100% of the first 2% of each employee's wages that are contributed and 25% of the next 4% of each employee's wages that are contributed. An employee must be employed on December 31 to receive that year's Company matching contribution, with the matching contribution funded annually in the January following the year in which the matching contribution was earned. The Company may also make additional discretionary profit sharing contributions to the plan on an annual basis as determined by the Board of Directors. The Company did not make any discretionary contributions to the 401(k) Plan during the three or nine months ended September 30, 2015 or 2014. The Company expensed matching contributions under the 401(k) Plan in the amounts of $4.8 million and $4.3 million for the three months ended September 30, 2015 and 2014, respectively. The Company expensed matching contributions under the 401(k) Plan in the amounts of $13.4 million and $12.5 million for the nine months ended September 30, 2015 and 2014, respectively.

Nonqualified deferred compensation plan:

The Company sponsors a nonqualified deferred compensation plan (the "Deferred Compensation Plan") for highly compensated employees whose contributions to the 401(k) Plan are limited due to the application of the annual limitations under the Internal Revenue Code. The Deferred Compensation Plan provides these employees with the opportunity to defer compensation, including salary and incentive based compensation, that was precluded under the Company's 401(k) Plan due to the annual limitations, which is then matched by the Company using the same formula as the 401(k) Plan. An employee must be employed on December 31 to receive that year's Company matching contribution, with the matching contribution funded annually in the January following the year in which the matching contribution was earned. In the event of bankruptcy, the assets of this plan are available to satisfy the claims of general creditors. The Company has an unsecured obligation to pay, in the future, the value of the deferred compensation and Company match adjusted to reflect the performance, whether positive or negative, of selected investment measurement options chosen by each participant during the deferral period. The liability for compensation deferred under the Deferred Compensation Plan was $16.1 million and $15.4 million as of September 30, 2015, and December 31, 2014, respectively, and was included within "Other liabilities" on the Condensed Consolidated Balance Sheets. The Company expensed matching contributions under the Deferred Compensation Plan in the amount of less than $0.1 million for each of the three months ended September 30, 2015 and 2014. The Company expensed matching contributions under the Deferred Compensation Plan in the amounts of $0.1 million and $0.2 million for the nine months ended September 30, 2015 and 2014, respectively.

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.

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.

As previously reported, the Company received a subpoena from the District Attorney of the County of Alameda, along with other environmental prosecutorial offices in the state of California, seeking documents and information related to the handling, storage and disposal of hazardous waste. Management has an ongoing and open dialogue with these agencies regarding this matter and is cooperating fully with the request; however, at this time a prediction of the ultimate outcome of these efforts cannot be determined.

As previously reported, on June 18, 2015, a jury in Greene County, Missouri returned an unfavorable verdict in a litigated contract dispute in the matter Meridian Creative Alliance vs. O'Reilly Automotive Stores, Inc, et. al. in the amount of $12.5 million. The Company strongly believes that the verdict was unjust and unsupported by the law and the underlying facts and, further, that there are several potential bases for reversal on appeal. The Company intends to vigorously challenge the verdict in the Court of Appeals. The Company currently has reserved $18.8 million with respect to this matter.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent accounting pronouncements

NOTE 9 - RECENT ACCOUNTING PRONOUNCEMENTS

In May of 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standard Update ("ASU") 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. In August of 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date" ("ASU 2015-14"), to defer the effective date of ASU 2014-09 by one year. Originally, for public companies, ASU 2014-09 was effective for annual reporting periods beginning after December 15, 2016, including periods within that reporting period, and could be adopted either retrospectively or as a cumulative effect adjustment at the date of adoption, with early adoption not permitted. For public companies, ASU 2015-14 changes ASU 2014-09 to be effective for annual reporting periods beginning after December 15, 2017, including periods within that reporting period, and can be adopted retrospectively or as a cumulative effective adjustment at the date of adoption, with early adoption allowed, but not before ASU 2014-09's original effective date of December 15, 2016. The Company will adopt this guidance beginning with its first quarter ending March 31, 2018. 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.

In January of 2015, the FASB issued ASU No. 2015-01, "Extraordinary and Unusual Items (Subtopic 225-20)" ("ASU 2015-01"). ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items; such that, an entity will no longer need to assess whether a particular event or transaction event is extraordinary. ASU 2015-01 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, and early adoption is permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2016. The application of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

In April of 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30)" ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. In August of 2015, the FASB issued ASU 2015-15, "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015, EITF Meeting" ("ASU 2015-15"), to update ASU 2015-03 to reflect a Securities and Exchange Commission change. ASU 2015-15 allows an entity, in the case of a line-of-credit arrangement, to either follow ASU 2015-03 or defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratable over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-03 is effective for annual reporting periods beginning after December 15, 2015, including periods within that reporting period, requires retrospective application, and early adoption is permitted. The Company will adopt this guidance with its first quarter ending March 31, 2016. The application of this guidance affects classification only, and therefore, it is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cashflows.

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 suppliers. Certain suppliers 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 supplier 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, which are recorded as obligations at the time of sale, 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.

Share repurchase program

NOTE 5 – SHARE REPURCHASE PROGRAM

In January of 2011, the Company's Board of Directors approved a share repurchase program. Under the program, 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's 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 4, 2015, and May 29, 2015, the Company's Board of Directors each time approved a resolution to increase the authorization amount under the share repurchase program by an additional $500 million, resulting in a cumulative authorization amount of $5.5 billion. Each additional $500 million authorization is effective for a three-year period, beginning on its respective announcement date.

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   September 30,				For the Nine Months Ended   September 30,

Total investment	$	274,213	$	387,461	$	849,145	$	687,086
