RECENT DEVELOPMENTS


We continue to prioritize the safety and wellness of our Team Members and our customers as we navigate the ongoing challenges resulting from the COVID-19 pandemic in the current environment. Vaccine availability, effectiveness and distribution, gradual reopening processes across many of our markets, government stimulus payments and enhanced unemployment benefits have positively impacted demand for the products we sell. We continue to keep our stores open and operating to meet our customers' critical needs, while also ensuring the safety of our Team Members and customers through strict adherence to our safety protocols; however, we cannot predict how long the current crisis will last or the extent of its impact on our customers, our Team Members and overall industry demand.

OVERVIEW



We are a specialty retailer of automotive aftermarket parts, tools, supplies, equipment and accessories in the United States and Mexico. We are one of the largest U.S. automotive aftermarket specialty retailers, selling our products to both DIY customers and professional



                                       16

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 profit dollars are, generally, 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. We have ongoing 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.

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. As of March 31, 2021, we operated 5,660 stores in 47 U.S. states and 22 stores in Mexico.

We are influenced by a number of general macroeconomic factors that impact both our industry and our consumers, including, but not limited to, fuel costs, unemployment trends, interest rates and other economic factors. Due to the nature of these macroeconomic factors, we are unable to determine how long current conditions will persist and the degree of impact future changes may have on our business. Macroeconomic factors, such as increases in the U.S. unemployment rate, and demand drivers specific to the automotive aftermarket, such as U.S. miles driven, have been pressured as a result of responses to the COVID-19 pandemic, such as stay at home orders, work from home arrangements, and reduced travel. However, government stimulus and unemployment benefits and the reopening processes have positively impacted our performance. We are unable to predict the ongoing and future impact of the pandemic on broader economic conditions or our industry.

We believe the key drivers of current and future long-term demand for 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 and average vehicle age.





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. In total, vehicles in the U.S. are driven approximately three trillion miles per year, resulting in ongoing wear and tear and a corresponding continued demand for the repair and maintenance products necessary to keep these vehicles in operation.

According to the Department of Transportation, the number of total miles driven in the U.S. decreased 13.2%, increased 0.9% and increased 0.4% in 2020, 2019 and 2018, respectively, and through February of 2021, year-to-date miles driven decreased 11.7%. Miles driven dramatically declined in 2020, as a result of responses to the COVID-19 Pandemic, and have remained below pre-pandemic levels.

Further government measures or consumer and business behavior could continue to have a negative impact on miles driven, but we are unable to predict the duration and severity of the impact to our business.

Size and Age of the Vehicle Fleet

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 10.4% from 2009 to 2019, bringing the number of light vehicles on the road to 278 million by the end of 2019. For the year ended December 31, 2020, the seasonally adjusted annual rate of light vehicle sales in the U.S. ("SAAR") was approximately 16.3 million, and for 2021, the SAAR is estimated to be approximately 17.8 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 4.1% to 5.7% annually. As a result, over the past decade, the average age of the U.S. vehicle population has increased, growing 18.0%, from 10.0 years in 2009 to 11.8 years in 2019. The outlook for SAAR is highly uncertain, as the severity and duration of the COVID-19 crisis is indeterminable; however, the rate of new vehicle sales in any given year represents a small percentage of the total light vehicle population and has a muted impact on the total number of vehicles on the road and average age of vehicles over the short term.

We believe the 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, interiors and exteriors, and the consumer's willingness to invest in maintaining these higher-mileage, better built vehicles. As the average age of vehicles 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.





                                       17

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 March 31, 2021, increased $614 million or 25% to $3.09 billion from $2.48 billion for the same period one year ago.

Comparable store sales for stores open at least one year increased 24.8% and decreased 1.9% for the three months ended March 31, 2021 and 2020, respectively.

Comparable store sales are calculated based on the change in sales for stores open at least one year and exclude sales of specialty machinery, sales to independent parts stores and sales to Team Members, as well as sales from Leap Day in the three months ended March 31, 2020. Online sales, resulting from ship-to-home orders and pickup in-store orders, for stores open at least one year, are included in the comparable store sales calculation.

The following table presents the components of the increase in sales for the three months ended March 31, 2021 (in millions):

We believe the increased sales are the result of store growth, 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. The government stimulus payments, enhanced unemployment benefits, lifting of stay at home orders and associated market reopening and recovery plans when combined with favorable industry dynamics, such as consumers investing in existing vehicles, led to strong demand for our products in the first quarter.

Our comparable store sales increase for the three months ended March 31, 2021, was driven by increases in average ticket values and transaction counts for both DIY and professional service provider customers. Average ticket values benefited from consumers spending additional time and money repairing and maintaining their vehicles in response to the COVID-19 and economic environment.

In addition, the improvement in average ticket values was the result of 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, more technically advanced vehicles require less frequent repairs, as the component parts are more durable and last for longer periods of time. This decrease in repair frequency creates pressure on customer transaction counts; however, when repairs are needed, the cost of replacement parts is, on average, greater, which is a benefit to average ticket values.

Improvement in transaction counts during the three months ended March 31, 2021, compared to the same period in the prior year, were primarily due to COVID-19 stay at home orders and business restrictions enacted during March of 2020 and resulted in immediate pressure to transaction counts for both DIY and professional service provider customers. The continued market reopening and recovery plans, ongoing government stimulus and favorable winter and spring weather conditions all benefited transaction counts in the current period.

We opened 66 net, new U.S. stores during the three months ended March 31, 2021, compared to opening 73 net, new U.S. stores during the three months ended March 31, 2020. As of March 31, 2021, we operated 5,660 stores in 47 U.S. states and 22 stores in Mexico compared to 5,512 stores in 47 U.S. states and 21 stores in Mexico at March 31, 2020.



                                       18



Gross profit:

Gross profit for the three months ended March 31, 2021, increased 27% to $1.64 billion (or 53.1% of sales) from $1.30 billion (or 52.3% of sales) for the same period one year ago. The increase in gross profit dollars for the three months ended March 31, 2021, was primarily the result of new stores and the increase in comparable store sales at existing stores. The increase in gross profit as a percentage of sales for the three months ended March 31, 2021, was due to a mix benefit driven by greater percentage of total sales generated from DIY customers, which carry a higher gross margin than professional service provider sales and leverage of fixed distribution costs, as a result of strong comparable store sales growth.

Selling, general and administrative expenses:

Selling, general and administrative expenses ("SG&A") for the three months ended March 31, 2021, increased 9% to $950 million (or 30.7% of sales) from $872 million (or 35.2% of sales) for the same period one year ago. The increase in total SG&A dollars for the three months ended March 31, 2021, was the result of additional facilities and vehicles to support our increased sales and store count, partially offset by prior year incremental SG&A expenses incurred from one additional day due to Leap Day. The decrease in SG&A as a percentage of sales for the three months ended March 31, 2021, was due to leverage of store operating costs on strong comparable store sales growth.

Operating income:

As a result of the impacts discussed above, operating income for the three months ended March 31, 2021, increased 63% to $691 million (or 22.4% of sales) from $424 million (or 17.1% of sales) for the same period one year ago.

Other income and expense:

Total other expense for the three months ended March 31, 2021, decreased 20% to $35 million (or 1.1% of sales) from $44 million (or 1.8% of sales) for the same period one year ago. The decrease in total other expense for the three months ended March 31, 2021, was the result of an increase in the value of our trading securities, as compared to a decrease in the value of our trading securities in the same period one year ago, and decreased interest expense on lower average outstanding borrowings and lower average cost of borrowings.

Income taxes:

Our provision for income taxes for the three months ended March 31, 2021, increased 95% to $154 million (23.5% effective tax rate) from $79 million (20.9% effective tax rate) for the same period one year ago. The increase in our provision for income taxes for the three months ended March 31, 2021, was the result of higher taxable income and lower benefits from renewable energy investment tax credits, partially offset by higher excess tax benefits from share-based compensation. The increase in our effective tax rate for the three months ended March 31, 2021, was the result of the benefit from investments in renewable energy tax credit funds in the prior period, partially offset by higher excess tax benefits from share-based compensation 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 March 31, 2021, increased 67% to $502 million (or 16.2% of sales) from $300 million (or 12.1% of sales) for the same period one year ago.

Earnings per share:

Our diluted earnings per common share for the three months ended March 31, 2021, increased 78% to $7.06 on 71 million shares from $3.97 on 76 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, and we are unable to predict the impact of the uncertainty and disruption caused by the COVID-19 pandemic on our ability to generate funds or maintain liquidity.

(1) Calculated as net cash provided by operating activities, less capital


    expenditures and excess tax benefit from share-based compensation payments,
    and investment in tax credit equity investments for the period.




Operating activities:

The increase in net cash provided by operating activities during the three months ended March 31, 2021, compared to the same period in 2020, was primarily due to an increase in net income, a larger decrease in net inventory investment and a larger increase in a net taxes payable position. The larger decrease in net inventory investment in the current period, as compared to the same period in the prior year, was primarily attributable to the strong comparable store sales growth and the resulting benefit to inventory turns. The larger increase in the net taxes payable position was primarily due to higher taxable income in the current period, as compared to the same period in the prior year, partially offset by the realization of renewable energy investment tax credits in the prior period.





Investing activities:

The decrease in net cash used in investing activities during the three months ended March 31, 2021, compared to the same period in 2020, was the result of a decrease in investments in renewable energy tax credit investment funds and a decrease in capital expenditures. The decrease in investments in renewable energy tax credit funds was the result of entering into tax credit equity investments in the comparable period in the prior year, and no investments in the current period, which are primarily for the purpose of receiving renewable energy investment tax credits. The decrease in capital expenditures was primarily due to the lower level of distribution expansion projects and new store project development in the current period, as compared to the same period in the prior year.





Financing activities:

The net cash used in financing activities during the three months ended March 31, 2021, versus net cash provided by financing activities during the three months ended March 31, 2020, was attributable to the net proceeds from the issuance of long-term debt and the net borrowings on our revolving credit facility in the comparable period in the prior year and an increase in repurchases of our common stock during the current period, as compared to same period in the prior year.

Unsecured revolving credit facility:

On April 5, 2017, the Company entered into a credit agreement (the "Credit Agreement"). The Credit Agreement provides for a five-year $1.2 billion unsecured revolving credit facility (the "Revolving Credit Facility") arranged by JPMorgan Chase Bank, N.A., which is scheduled to mature in April 2022. 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 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 $600 million, provided that the aggregate amount of the commitments does not exceed $1.8 billion at any time.

As of March 31, 2021, we had outstanding letters of credit, primarily to support obligations related to workers' compensation, general liability and other insurance policies, in the amount of $84.0 million, reducing the aggregate availability under the Credit Agreement by that amount. As of March 31, 2021, we did not have any outstanding borrowings under our Revolving Credit Facility.

Senior Notes:

As of March 31, 2021, we have issued and outstanding a cumulative $4.2 billion aggregate principal amount of unsecured senior notes, which are due between 2021 and 2031, with UMB Bank, N.A. and U.S. Bank as trustees. Interest on the senior notes, ranging from 1.750% to 4.625%, is payable semi-annually and is computed on the basis of a 360-day year. None of our subsidiaries is a guarantor under our senior notes.





                                       20

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, create certain liens on assets to secure certain debt and enter into certain sale and leaseback transactions, and limit our ability to merge or consolidate with another company or transfer all or substantially all of our 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 March 31, 2021, 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 2.50:1.00 and a maximum consolidated leverage ratio of 3.50:1.00. The consolidated fixed charge coverage ratio includes a calculation of earnings before interest, taxes, depreciation, amortization, rent and non-cash share-based compensation expense to fixed charges. Fixed charges include interest expense, capitalized interest and rent expense. 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, five-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 6.46 times and 5.08 times as of March 31, 2021 and 2020, respectively, and a consolidated leverage ratio of 1.77 times and 2.45 times as of March 31, 2021 and 2020, respectively, remaining in compliance with all covenants related to the borrowing arrangements.

Free cash flow, the consolidated fixed charge coverage ratio and the 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



                                       22

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 10, 2021, our Board of Directors approved a resolution to increase the authorization amount under our share repurchase program by an additional $1.0 billion, resulting in a cumulative authorization amount of $15.8 billion. The additional authorization is effective for a three-year period, beginning on its respective announcement date.





The following table identifies shares of our common stock that have been
repurchased as part of our publicly announced share repurchase program for the
three months ended March 31, 2021 and 2020 (in thousands, except per share
data):


                              For the Three Months Ended
                                      March 31,
                                2021               2020
Shares repurchased                  1,475              1,484
Average price per share    $       450.65     $       386.71
Total investment           $      664,533     $      574,037

As of March 31, 2021, we had $817.0 million remaining under our share repurchase program. Subsequent to the end of the first quarter and through May 7, 2021, we repurchased less than 0.1 million additional shares of our common stock under our share repurchase program, at an average price of $556.69, for a total investment of $8.0 million. We have repurchased a total of 82.5 million shares of our common stock under our share repurchase program since the inception of the program in January of 2011 and through May 7, 2021, at an average price of $181.09, for a total aggregate investment of $14.9 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, 2020.





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, 2020.





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 costs 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.
