We encourage you to access the meeting in advance of the designated start time.

How will the Annual Meeting be conducted and will there be a question and answer session?

All of our board members are expected to join the Annual Meeting and will be available to respond to questions germane to the business matters presented during the meeting. We intend to answer questions submitted during the meeting that are germane to business matters of the meeting, and in accordance with our Rules for Conduct, which will be able to be viewed on the day of and during the Annual Meeting. Questions will be grouped by topic, and substantially similar questions will be answered only once. Questions should be succinct and cover only one topic per question. To promote fairness, efficient use of the Company's resources and ensure all shareholder questions are able to be addressed, we will respond to no more than three questions from any single shareholder. If there are any matters of individual concern to a shareholder or if a question posed was not otherwise answered, we will provide an opportunity for shareholders to contact us separately after the Annual Meeting through our Investor Relations website,http://corporate.oreillyauto.com/contact-us, or by contacting us at [phone].

What is the record date for the Annual Meeting?

The record date is March 4, 2021. Shareholders of record at the close of business on March 4, 2021, will be entitled to vote at the Annual Meeting. Each share of common stock will have one vote on each matter to be voted upon.

Officer and Director Stock Ownership Guidelines

The Board adopted stock ownership requirements for the Company's independent Directors, executive officers and executive and senior vice presidents to further align their interests with those of the Company's shareholders. The Compensation Committee reviews the stock ownership guidelines and reviews progress toward meeting ownership requirements quarterly. The Compensation Committee has discretion to waive these guidelines; however, it has never done so.

The Company's independent Directors are required to own shares of the Company's common stock valued at a minimum of $150,000 within five years of the date they first become a Director. For purposes of the guidelines, common stock ownership includes shares owned by the Director, directly or indirectly, and vested stock options granted to the Director, but excludes unvested restricted share awards. As of December 31, 2020, the total stockholdings of each of the independent directors, who has been serving as a Director for at least five years, satisfied their respective stock ownership requirement.

The Company's executive officers and executive and senior vice presidents are required to own shares of the Company's common stock valued at the minimum of a specified multiple of their base salary within five years of first assuming their respective positions. For purposes of the guidelines, common stock ownership includes shares owned by the officer directly, shares held by the officer in the

Position	Minimum Ownership Requirement Multiple of Salary
Chief Executive Officer	5x
Chief Operating Officer	3x
Chief Financial Officer	3x
Executive Vice Presidents	3x
Senior Vice Presidents	2x

Company's Employee Stock Purchase Plan, shares held by the officer in the Company's Profit Sharing and Savings Plan and the tax affected intrinsic value of the officer's vested stock options granted under the Company's incentive plans. Individuals who do not achieve the required level of ownership within the prescribed period of time may, at the discretion of the Compensation Committee, be required to hold 50% of net after-tax shares issued upon the exercise of any of their stock options and may not be allowed to sell any other shares of the Company that they may own. The stock ownership requirement does not apply after the executive officer or executive or senior vice president reaches age 62. The Compensation Committee may waive these guidelines at its discretion; however, it has never done so. As of December 31, 2020, each of the Company's executive officers and executive and senior vice presidents, who had been in their positions for at least five years, satisfied the stock ownership requirement applicable to each of them.

The following table identifies the executive officers' and executive and senior vice presidents' ownership requirement as of December 31, 2020:

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" EACH OF THE ELECTED NOMINEES.

The Board continues to place a significant focus on its structure, tenure and succession planning. In consideration of these factors, the Board's current Executive Chairman, David O'Reilly, has made the decision to step down from the Chairman role at the end of the current Director term in May of 2021. Mr. O'Reilly has been a member of the Company's executive management team and Board since the Company's initial public offering in 1993 and has provided exceptional leadership and direction during that period. Mr. O'Reilly has also heavily focused on the evaluation and development of his successor. After careful consideration and discussion, the Corporate Governance/Nominating Committee has recommended, and the Board has approved, the appointment of the Company's current Executive Vice Chairman, Greg Henslee, to the position of Executive Chairman effective immediately following the Annual Meeting, and subject to Mr. Henslee's election as a Director at the Annual Meeting. Mr. Henslee has over 39 years of automotive aftermarket experience, including 36 years with the Company, and has also been a member of various automotive aftermarket industry association boards. In addition, Mr. Henslee's knowledge, experience and leadership abilities make him the ideal successor to Mr. O'Reilly as Executive Chairman. Mr. O'Reilly has expressed his strong desire to continue to serve on the Company's Board. The Corporate Governance/Nominating Committee has recommended, and the Board has approved, the appointment of Mr. O'Reilly to the position of Executive Vice Chairman effective immediately following the Annual Meeting, and subject to Mr. O'Reilly's election as a Director at the Annual Meeting. In his new role, Mr. O'Reilly will continue to provide his invaluable knowledge and experience to the Board and will be a trusted advisor to Mr. Henslee, as he accepts his larger role in leading and directing the Board and the Company going forward.

INFORMATION CONCERNING THE BOARD OF DIRECTORS

Director Independence

Rules of the Nasdaq Stock Market (the "Nasdaq") require that a majority of the Board be "independent." Under the Nasdaq rules, a director or director nominee is independent if he or she is not an officer or employee of the Company and does not have any relationship with the Company which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. The Board has reviewed the independence of its Directors and director nominee under the Nasdaq rules. During this review, the Board considered transactions and relationships between each Director or any member of his or her family and the Company during 2020. Please see discussions in "Affiliated Relationships" and "Certain Relationships and Related Transactions" sections for further descriptions, by specific category and type, of the transactions and relationships reviewed. Consistent with these considerations, the Board has determined that Messrs. Burchfield, Hendrickson, and Murphy, and Mss. Perlman, Sastre and Weiss ("independent Directors") are independent under the Nasdaq rules.

Affiliated Relationships

David O'Reilly and Larry O'Reilly, Directors of the Board, are siblings. David O'Reilly also serves as Executive Chairman of the Board of the Company. Greg Henslee, Director of the Board, served as the Company's Chief Executive Officer from 2005 through 2018. Greg Henslee also serves as Executive Vice Chairman of the Board of the Company. In addition, Rosalie O'Reilly Wooten, who retired from the Board effective May 14, 2020, are siblings with David O'Reilly and Larry O'Reilly.

Leadership Structure

The Company's leadership structure, within its Board, consists of a Chairman of the Board, two Vice Chairmen of the Board, an Independent Lead Director, an Audit Committee, a Corporate Governance/Nominating Committee and a Compensation Committee. The Independent Lead Director also serves on the Audit Committee and the Compensation Committee. All Committee members satisfy the independence requirements under the Nasdaq rules. The Company's Bylaws permit the positions of Chairman of the Board and Chief Executive Officer to be held by the same person; however, the Board believes these roles and their attendant responsibilities should be separate and fulfilled by two separate individuals. The Company believes having separate roles allows its Board to effectively provide guidance to and oversight of its management. As a result, David O'Reilly serves in the role of Chairman of the Board and Gregory D. Johnson serves in the role of Chief Executive Officer.

Independent Lead Director

From time to time, in the interest of sound corporate governance, the Board may appoint an Independent Lead Director. The Board believes that the designation of an Independent Lead Director improves the functionality of the Board and its Committees and aids in the fiduciary obligations each Director has to the Company and its shareholders. In May of 2018, the Corporate Governance/Nominating Committee nominated, and the Board approved, Jay D. Burchfield to serve as Independent Lead Director. Mr. Burchfield has served as Independent Lead Director since that time.

The responsibilities of the Independent Lead Director include, but are not limited to, the following:

• • Serves as a liaison among other Directors, with the Company's management, between Board committees and the Board;

• • Presides at Board meetings in the absence of the Chairman of the Board, or at the request of the Chairman of the Board;

• • Ensures Board leadership in the absence or incapacitation of the Chairman of the Board;

• • Chairs executive sessions involving only the independent Directors, develops the agenda for executive sessions to ensure that independent Directors have adequate opportunities for these meetings to be held and adequate time to discuss issues and communicates with the Company's management, as appropriate, the results of the executive sessions;

• • Consults with the Chairman of the Board as to the appropriate schedules and agendas of Board meetings to ensure there is sufficient time available for serious discussion of appropriate topics proposed by the independent Directors;

• • Advises the Chairman of the Board on the conduct of Board meetings to facilitate teamwork and communication among independent and non-independent Directors;

• • Together with the Chairman of the Board, collaborates with the Company's management to determine the information and materials provided to the Directors, so that the independent Directors have adequate resources, especially by way of full, timely and relevant information, to support their decision-making responsibilities;

• • Entitled to request materials from and receive notice of, and attend, all meetings of Board committees;

• • Collaborates with the Chairman of the Board and Corporate Governance/Nominating Committee on Board succession planning;

• • Is available to advise committee chairs in fulfilling their designated roles and responsibilities to the Board;

• • Acts as the focal point on the Board concerning issues such as corporate governance and suggestions from independent Directors and monitors and coordinates with the Company's management on corporate governance issues and developments;

• • Collaborates with the Corporate Governance/Nominating Committee to ensure a succession plan is in place for the Company's Chief Executive Officer;

• • Collaborates with the Board to guide the Company's management on strategic issues and long-term planning;

• • Consults with the Chairman of the Board on such matters as are pertinent to the Board and the Company;

• • Is available for direct communication and consultation with shareholders, upon request through Board approved procedures; and

• • Performs such other duties as the Board or Chairman of the Board may delegate, from time to time.

Meeting Attendance

During 2020, four regularly scheduled meetings and one strategic planning meeting of the Board were held. During such year, each current Director attended 100% of the total number of meetings of the Board during his or her term of service, with the exception of Mr. Burchfield and Mr. Larry O'Reilly, who each attended 80% of the total number of meetings. During 2020, each independent Director attended 100% of the total number of meetings held by all committees of the Board for which he or she served, with the exception of Mr. Burchfield who attended 85% and Ms. Sastre who attended 80% of the total number of meetings held by all committees of the Board for which each served.

Time is allotted at each Board meeting for an executive session involving only the independent Directors. The Company's independent Directors held four closed-session meetings during 2020, and each current independent director attended all meetings during his or her term of service, with the exception of Mr. Burchfield who attended 75% of the total number of meetings.

The Company encourages, but does not require, the members of its Board to attend the Annual Meeting. Each director then serving on the Board attended the Company's 2020 Annual Meeting.

Committees of the Board

The Board has three standing committees, the Audit Committee, the Compensation Committee and the Corporate Governance/Nominating Committee. Each committee is governed by a written charter and is comprised solely of independent Directors in accordance with the Nasdaq Listing Qualifications. Charters for each committee are available on the Company's website atwww.OReillyAuto.com and can be obtained free of charge by written request to the attention of the Secretary at the Company's address appearing on the first page of this proxy statement or by telephone at [phone].

Because David O'Reilly, Larry O'Reilly and Greg Henslee do not qualify as independent Directors, they do not participate on any committees of the Board.

Audit Committee

Number of Members:	Six
Members:	Thomas T. Hendrickson (Chair), Jay D. Burchfield, John R. Murphy, Dana M. Perlman,
Maria A. Sastre and Andrea M. Weiss
Number of Meetings during 2020:	Eight
Purpose and Functions:
The purpose of the Audit Committee is to

• (i) review reports of the Company's financial results, audits and internal controls and communicate the results of those evaluations to management;

Number of Meetings during 2020:	Five
Purpose and Functions:

The Board has determined that each member of the Audit Committee is "independent" pursuant to the Nasdaq rules, as well as the independence requirements for audit committee members under Rule 10A-3 promulgated under the Exchange Act. In addition, the Board has determined that Mr. Hendrickson, Chair of the Audit Committee, is qualified as an audit committee financial expert, as that term is defined in the rules of the SEC. The Company's Audit Committee Charter may be viewed on its website atwww.OReillyAuto.com.

Compensation Committee

The purpose of the Compensation Committee is to

• (i) act on behalf of the Board with respect to the establishment and administration of the policies governing the annual compensation of the Company's executive officers;

• (ii) define and articulate the Company's overall executive compensation philosophy and to administer and approve all elements of compensation for the Company's executive officers and senior management;

Because the Company's executive leadership is of critical importance to the Company's success, the succession planning process is led by the Compensation Committee. This committee reviews the Company's succession planning practices and procedures and makes recommendations to the Board concerning succession developments, while ensuring the appropriate succession plans are in place for key executive positions.

The Committee has the authority to retain consultants and advisors, as it may deem appropriate in its discretion. The Committee has, from time to time, historically utilized third party compensation survey data and/or outside consultant advisors in order to achieve its goal of attracting and retaining executive officers who contribute to the long-term success of the Company. During 2020, the Company did not engage an outside consultant advisor for compensation advisory services. The Company's Compensation Committee Charter may be viewed on its website atwww.OReillyAuto.com.

Corporate Governance/Nominating Committee

Number of Members:	Three
Members:	Dana M. Perlman (Chair), John R. Murphy and Andrea M. Weiss
Number of Meetings during 2020:	Four

Purpose and Functions:

The purpose of the Corporate Governance/Nominating Committee is to

• (i) establish criteria for the selection of Directors, identify any additional skills sets or attributes necessary to fill gaps on the current Board and to recommend to the Board the nominees for Director in connection with the Company's Annual Meeting of the shareholders;

• (ii) take a leadership role in shaping the Company's corporate governance policies and to issue and implement the Corporate Governance Principles of the Company;

• (iii) develop and coordinate annual evaluations of the Board, its committees and its members;

• (v) adhere to all legal standards required by the SEC and Nasdaq; and

• (vi) review and assess the Company's environmental, sustainability, social and governance policies, goals and programs, and make recommendations to management based on their review and assessment.

The Corporate Governance/Nominating Committee conducts an annual Board evaluation process to determine the effectiveness of the Board and as a tool to aid in continuous improvement. The Chair of the Corporate Governance/Nominating Committee, in partnership with the Company's outside counsel, provides questionnaires to the Board, which are completed and returned directly to the Company's outside counsel who compiles the responses and reports the results on an anonymous basis to the Corporate Governance/Nominating Committee Chair for evaluation and discussion with the Board's Lead Independent Director and the Chairman of the Board. Topics in the questionnaire include:

• • Board effectiveness and leadership structure;

• • Board member skills and performance;

• • Board composition, including diversity;

• • Board succession planning;

• • Board committee effectiveness; and

• • Board interaction and communication with Company management.

In recent years, the Board's self-evaluation process has contributed to improve Board diversity, changes in Board committee membership and committee Chairs, increased focus on Board succession planning and Board refreshment and an increased focus and reporting on the Company's environmental, sustainability, social and governance policies and programs, including enhanced shareholder outreach.

The Company's Corporate Governance Principles may be viewed along with the Corporate Governance/Nominating Committee Charter on its website atwww.OReillyAuto.com.

The Corporate Governance/Nominating Committee does not have a written policy on the consideration of Director Candidates recommended by shareholders. It is the view of the Board that all candidates, whether recommended by a shareholder or the Corporate Governance/Nominating Committee, shall be evaluated based on the same established criteria for persons to be nominated for election to the Board and its committees. The established criteria for persons to be nominated for election to the Board and its committees, taking into account the composition of the Board as a whole, at a minimum, includes

• • a candidate's qualification as "independent" under the federal securities laws and the rules and regulations of the SEC and Nasdaq applicable to the Board and each of its committees;

• • depth, breadth and diversity of experience within the Company's industry and otherwise;

• • commitments outside of the Board and the ability to devote adequate time to Board and committee matters;

• • special areas of expertise;

• • accounting and financial knowledge;

• • willingness to apply sound and independent business judgment;

• • leadership ability;

• • experience in developing and assessing business strategies;

• • corporate governance expertise;

• • risk management skills; and

• • for incumbent members of the Board, the past performance of the incumbent director.

The Corporate Governance/Nominating Committee regularly engages and considers director succession for the members of its Board, committees and committee chairs to ensure a mix of knowledge and abilities, expertise and tenure that promote and support the Company's long-term success, while giving consideration to evolving skills, perspective and experience needed on the Board to perform its corporate governance role. In addition, when the Corporate Governance/Nominating Committee seeks a new candidate for directorship, it seeks qualifications from the individual that satisfy the established criteria for a person to be nominated and a candidate that will complement the attributes and perspective of the other members of the Board. As the Company's strategic priorities and the composition of the Board evolve, the priorities and emphasis of qualifications the Corporate Governance/Nominating Committee is seeking in a candidate will change from time to time. Individuals identified by the Corporate Governance/Nominating Committee as qualified to become directors are then recommended to the Board for nomination, and the Board determines the nominees for election after considering the recommendation and report of the Corporate Governance/Nomination Committee.

Finding qualified candidates interested in serving as director is of the highest level of importance to the Corporate Governance/Nominating Committee. As such, the Corporate Governance/Nominating Committee may use any and all appropriate methods at its disposal for identifying candidates for election. The Corporate Governance/Nominating Committee's methods for identifying candidates for election to the Company's Board include the solicitation of possible candidates from a number of sources, including engaging with outside search firms, from members of its Board, its executives, individuals personally known to the members of its Board and other research. Shareholders wishing to recommend a candidate for nomination as a director are requested to send the recommendation in writing to O'Reilly Automotive, Inc. Corporate Governance/Nomination Committee, attention to Tricia Headley, at 233 South Patterson Avenue, Springfield, Missouri 65802. The Board believes it is best qualified to evaluate candidates based on its knowledge of the Company's business structure, and the Corporate Governance/Nominating Committee may retain one or more third-party search firms to identify suitable candidates.

Shareholder Nominations

A shareholder who desires to nominate one or more persons for election as director(s) shall deliver "timely notice" (as defined in Section 12, Article II of the Company's Bylaws) of the shareholder's intent to make such nomination or nominations, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Company at the Company's address appearing on the first page of this proxy statement. In accordance with Section 13, Article II of the Bylaws, such notice shall set forth

• (i) the name and address of record of the shareholder who intends to make the nomination;

• (ii) the class and number of shares of the capital stock that are beneficially owned by the shareholder on the date of such notice;

• (iii) the name, age, business and residential addresses, and principal occupation or employment of each proposed nominee;

• (iv) a description of all arrangements or understandings between the shareholder and each nominee, and other arrangements or understandings known to the shareholder, pursuant to which the nomination or nominations are to be made by the shareholder; any other information regarding each proposed nominee that would be required to be included in a proxy statement filed with the SEC; and

• (v) the written consent of each proposed nominee being so named to serve as a Director of the Company.

The presiding officer of a meeting may, if the facts warrant, determine at the meeting that a nomination was not made in accordance with the foregoing procedure, and if he or she should make that determination, he or she shall so declare at the Annual Meeting, and the defective nomination shall be disregarded.

Risk Oversight

It is management's responsibility to assess and manage the Company's exposure to various risks and bring the Company's most material risks to the Board's attention. The Board has oversight responsibility of the processes established to report and monitor systems for material risks applicable to the Company. In its oversight role, the Board annually reviews the Company's strategic plan, which addresses, among other things, the risks and opportunities facing the Company.

A quarterly risk overview is provided to the Board by the Company's General Counsel, the Company's Senior Vice President of Information Technology and the Company's Vice President of Treasury and Government Affairs, which details the Company's current and potential risk exposure to litigation, information technology, cybersecurity and self-insurance. In addition, quarterly operational updates and risk assessments are provided by Vice Presidents of selected operational areas, including acquisitions, store operations, distribution operations, finance and real estate.

The Board has delegated certain risk management oversight responsibility to the Board committees, as detailed below. Each committee regularly reports to the full Board.

Audit Committee Risk Oversight

The Audit Committee provides risk management oversight for areas including economic, financial (such as accounting, credit, liquidity and tax), legal, compliance and regulatory risks. As part of its responsibilities as set forth in its charter, the Audit Committee is responsible for discussing with management the Company's major financial risk exposures and the steps management has taken to monitor and control those exposures, including the Company's risk assessment and risk management policies. Specific risk assessment areas include reviews of the Company's Corporate Risk Assessment and Management Status Report (which identifies the material strategic and operational Company business risks and the controls that respond to and mitigate those risks), the Company's Code of Conduct and Ethics program compliance, related party transactions, insider trading policy compliance, the Company's TIPS Hotline activity, the appropriate interpretation and application of new accounting standards, the internal auditor's comprehensive audit plan and the external auditor's independence and audit effectiveness. The Audit Committee reviews, with management, the Company's financial performance and financing arrangements and meets with the Company's internal and external auditors to review the Company's compliance with all applicable financial reporting and Sarbanes-Oxley requirements. The Audit Committee also reviews, with management, the status of the Company's information technology and cybersecurity programs and initiatives, business continuity planning and PCI compliance.

Compensation Committee Risk Oversight

The Compensation Committee provides risk management oversight for areas including compensation, retention, human capital management and diversity and inclusion risks. Specific risk assessment areas include reviews of executive officer succession planning, senior management development plans and approval of promotions, total compensation for the Company's executives and senior management, including base salary, incentive compensation, benefits, and perquisites to ensure they are market competitive and consistent with the Company's performance goals and ensures that these compensation plans and arrangements do not create inappropriate risks. In addition, the Compensation Committee assesses risks for non-executive human capital management, including diversity and inclusion and recruiting and retention.

Corporate Governance/Nominating Committee Risk Oversight

The Corporate Governance/Nominating Committee provides risk management oversight for areas including director succession planning and skills assessment, operations, business, competitive and reputation risks. Specific risk assessment areas include reviews of the Company's corporate governance guidelines and their implementation, the Company's Code of Conduct and Ethics program compliance, the Board committee charters, the Company's Corporate Governance Principles, updates on shareholder activism and the Company's environmental, social and governance policies and disclosures.

Under the oversight and direction of the Corporate Governance/Nominating Committee, the Company issued its inaugural 2018 Sustainability, Social, & Governance Report in 2019, which illustrates the Company's approach to human capital management, workforce diversity and inclusion, labor practices, environmental consciousness and governance initiatives, and in 2020, the Company issued an update to its inaugural report, which illustrates the Company's continued efforts in these areas. The Report is available on the Company's website atwww.OReillyAuto.com.

Board Diversity

In selecting a Director nominee, the Corporate Governance/Nominating Committee focuses on skills, viewpoints, expertise and background that would complement the existing Board. While the Board does not have a formal policy on Board diversity as it relates to the selection of nominees for the Board, the Corporate Governance/Nominating Committee will consider diversity in market knowledge, experience, employment, ethnicity, gender and geography among other factors. Decisions by the Board regarding continued service of Directors are made based on expected contributions to the Board in furtherance of the interests of shareholders.

Director Skills and Composition Matrix

The Corporate Governance/Nominating Committee reviewed the core competencies that it believes should be represented on our Board and believes that the qualifications and skills set below reflect the appropriate mix of experiences that, taken together, provide the variety and depth of knowledge necessary for effective oversight, direction and vision for the Company. The following table highlights specific information concerning each Director nominee and the key experience, qualifications and skills they bring to our Board; their diversity, age, independence and tenure are included as well.

Compensation of Directors

Independent Directors

Independent Directors are paid an annual fee and meeting fees for attendance at each Board and Committee meeting. The Independent Lead Director is paid an additional annual fee for service on the Board. Each Committee Chair is paid an additional annual fee for service as chair of each respective Committee.

To assist the Company in recruiting and retaining qualified Directors, the Company also awards each independent Director an annual restricted share award that vests in one installment after a one-year period, except for awards issued prior to May 2020, which vest in three equal annual installments. Upon resignation from the Board for any reason other than retirement, death or disability, all outstanding, unrested equity awards are immediately forfeited. The Board makes an annual determination of the number of restricted shares to be awarded to each independent Director.

The following table summarizes the compensation paid to the independent Directors, including stock awards, for the year ended December 31, 2020:

Annual fee	$ 85,000
Annual Independent Lead

approximately $145,000. These restricted shares vest in one installment over a one-year period
commencing on the first anniversary of the award. In May of 2020, each independent Director
received 357 restricted shares awarded at a price of $407.12 per share.
Non-qualified stock options	No stock option awards were granted during 2020.

$ 7,500 Compensation Committee$ 5,500 Corporate Governance/Nominating Committee

Independent Director fees in the aggregate amount of $603,000 were paid during 2020 and independent Director restricted stock awards with an aggregate fair value of $872,051 were granted in 2020.

Affiliated Directors

The Affiliated Director compensation plan provides for an annual cash retainer of $240,000 and quarterly meeting fees of $2,500 for attendance at each Board meeting to affiliated Directors (Larry O'Reilly). Affiliated Directors are not paid any other fee amounts and are not granted equity awards in their capacity as directors.

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee is now, nor has ever been, an officer or an employee of the Company or any of its subsidiaries. None of the Company's executive officers served as a director or as a member of a compensation committee (or other committee serving an equivalent function) of any other entity, one of whose executive officers served as a director of the Company or a member of the Compensation Committee during 2020.

COMPENSATION OF EXECUTIVE OFFICERS

Compensation Discussion and Analysis

This section describes the compensation packages of the Company's principal executive officer, principal financial officer, and three other most highly compensated officers who were employed by the Company on December 31, 2020 (such individuals are referred to as the "Named Executive Officers" or "NEOs" in this proxy statement). The NEOs and their positions are identified below:

• • David O'Reilly - Executive Chairman of the Board

• • Greg Henslee - Executive Vice Chairman of the Board

• • Gregory D. Johnson - Chief Executive Officer and Co-President

• • Jeff M. Shaw - Chief Operating Officer and Co-President

• • Tom McFall - Chief Financial Officer and Executive Vice President

Executive summary

The Compensation Committee of the Board is responsible for reviewing the performance of the Company's NEOs, Executive Vice Presidents and Senior Vice Presidents (together, its "executive officers"), recommending to the Board compensation packages and specific compensation levels for its executive officers and other management team members, establishing policies and guidelines for other benefit programs and administering the award of stock options and other stock-based incentives under the Company's incentive plans.

At the 2020 Annual Meeting, over 92% of the votes cast in the advisory vote on executive compensation, which were present and entitled to vote on the matter, were in favor of the compensation of the Company's NEOs as disclosed in the 2020 proxy statement. The Board believes that the outcome of this proposal evidences the commitment of the Compensation Committee to open dialogue with the Company's shareholders regarding the Company's executive compensation program, and the Compensation Committee has and will continue to consider these voting results and shareholder sentiments generally as it formulates and implements an executive compensation program designed to align the long-term interests of the Company's executive officers with the interests of its shareholders.

The policies and procedures of the Compensation Committee are designed to assist the Board in its oversight of the implementation and effectiveness of its policies and strategies regarding the investment in the Company's most important asset: its employees (whom the Company refers to as "Team Members"). These strategies and policies include, but are not limited to:

• • recruiting and retaining qualified Team Members;

• • supporting the career development and progression of Team Members;

• • management succession, in conjunction with the Company's Corporate Governance/Nominating Committee; and

• • other employment practices.

Compensation objectives and philosophy

The main objective of the Company's compensation philosophy is to provide its executive officers and management with a total compensation package that is competitive and equitable, and which encourages and rewards performance based in part upon the Company's performance in terms of increases in shareholder value. The Company's compensation objectives include both long-term, share-based incentives and short-term, cash incentives. The Company believes that aligning the interests of its executives and management with those of its shareholders further promotes the success of not only the Company, but also its Team Members.

Risk assessment of compensation programs

The Compensation Committee has reviewed the potential effects of the various components of the Company's executive officers' compensation and benefits programs on individual and collective behavior and, ultimately, on its risk profile and overall approach to risk management. During its review, the Compensation Committee focused on the Company's short-term incentives, long-term incentives, and change in control benefits as having the greatest potential to create incentives for individual or collective risk taking. Following a thorough review of these and the other components of the Company's compensation and benefits programs, the Compensation Committee has determined that the programs do not create any incentives with respect to individual or collective behavior that are likely to have a material adverse effect upon either its risk profile or overall approach to risk management.

Additionally, the Company's non-executive officer and management compensation policies and practices do not excessively incentivize or create need for inappropriate risk-taking by its Team Members, and therefore, it is not reasonably likely that current compensation policies and practices would have a material adverse effect on the Company.

Overview of compensation programs

The key elements of the compensation packages for the Company's executive officers, including the NEOs, are base salary, annual cash incentive compensation and long-term, share-based incentives. In determining the composition of elements in each compensation package, the Compensation Committee aims to create a balanced set of rewards, utilizing market-driven influences and external compensation benchmarks, as well as the Company's current cash considerations. To ensure that the Company thrives in the competitive talent market, the Compensation Committee reviews industry resources, references and other benchmark reports to determine competitive market ranges and reasonable levels of compensation.

In reviewing the compensation packages of each of the Company's executive officers and management, the Compensation Committee tallies the corresponding dollar value of each element of an individual's compensation, including salary, incentive compensation, accumulated realized and unrealized share-based compensation gains, the dollar value to such individual and cost to the Company of all perquisites and other personal benefits, the earnings and accumulated benefits under the Company's non-qualified deferred compensation program and the potential impact of several potential severance and change-in-control scenarios. For new appointments to senior executive management, the Company's management presents compensation recommendations to the Compensation Committee for consideration.

Competitive assessments

The Company's Human Resources Department provides the Compensation Committee with industry benchmark information and compensation survey data from the companies in its peer group, including peer salary, bonus, incentive compensation, share-based compensation and other compensation. The Compensation Committee considers the Company's relative performance compared with an established group of peer companies in the automotive aftermarket industry, other specialty retailers.

The group of peer companies is reviewed annually by the Compensation Committee to ensure that the comparisons are meaningful. The Compensation Committee evaluates peers that conduct business outside of the automotive aftermarket industry based on criteria such as revenue, operating margin, net income, market capitalization, team member count and one and three year total shareholder returns, as applicable. In addition to these key financial and operational metrics, the Compensation Committee also evaluates potential peers based on competition for team member recruitment and companies whose general customer demographics are similar to those of O'Reilly's.

Based on its annual review using the previously described criteria, the Compensation Committee removed two companies from the prior year's peer group and added two companies to the Company's 2020 peer group. The companies added and removed from the peer group are identified in the following table:

Peer Group Changes

Removal from Peer Group	Addition to Peer Group
Kohl's Corporation	The Home Depot, Inc.

The range, mean and median revenue and market capitalization of the Company's 2020 peer group, as well as those metrics for O'Reilly, as of December 31, 2020, are identified in the following table (in billions):

December 31, 2020

Mean	$24.39	$41.80
Median	$12.84	$15.91
O'Reilly Automotive, Inc.	$11.60	$32.19

The Compensation Committee also considers broad-based survey data, compiled by Equilar, Inc., of total compensation for top management at companies with total revenues comparable to the total revenues of the Company. The Compensation Committee uses the industry and market survey data for context in reviewing the overall compensation levels and maintaining a reasonable and competitive compensation program. The Compensation Committee does not use this data or peer group data to set specific compensation benchmarks for a position or for any element of compensation. Rather, the Compensation Committee evaluates the overall performance of the Company and the individual performance of management to set compensation at reasonable and competitive levels.

Base salary

The Company provides competitive annual base salaries to its executive officers and management in recognition of their job responsibilities. In determining annual base salary, it is the Compensation Committee's goal to bring the salaries of the Company's executive officers and management in line with base compensation being paid by its peer group. The Compensation Committee specifically reviews compensation information from the publicly traded automotive aftermarket companies in its peer group and compensation surveys and data from the other specialty retailers in its peer group. The Compensation Committee believes that the Company's principal competitors for its executive officers are not necessarily the same companies that would be included in a peer group compiled for purposes of comparing shareholder returns. Consequently, the companies that are reviewed for such compensation purposes may not be the same as the companies comprising the indices included in the Annual Report of the Company for 2020 that accompanies this proxy statement. The Compensation Committee increased base salary levels in 2020 for the Company's NEOs to maintain compensation at competitive levels and to reflect Company performance and the individual performance of each of its NEOs.

Incentive compensation plan

The Company provides competitive annual incentive compensation as a percent of base salary based on achievement of certain objective performance goals established by the Compensation Committee each year in order to motivate attainment of short-term goals, link annual cash compensation to achievement of annual priorities and reward individual performance and contributions.

At the beginning of each year a comprehensive operating plan is developed, which contains estimates for the Company's projected performance for the year, by reviewing the Company's historical performance, trends in the automotive aftermarket and retail industry and the performance of industry peers and other comparable companies. The targets for the incentive compensation plans set by the Compensation Committee generally correspond to this operating plan. The comprehensive operating plan for the 2020 fiscal year was approved by the Board in January of 2020 and reflects the projected results for the 2020 fiscal year. The Company's actual performance in each of the target areas is compared to the individual targets predetermined by the Compensation Committee to determine the incentive amount, if any, earned by each executive officer. Upon achievement of such performance goals, executive officers receive incentive compensation based upon a percentage of their respective base salaries for the attainment of a defined performance goal.

The overall potential value varies depending upon the executive's position; however, under the Company's 2017 Incentive Award Plan, the maximum aggregate amount of cash compensation that may be paid to any one participant in any year is $10,000,000. For 2020, the Company's Chief Executive Officer, Mr. Johnson, and Chief Operating Officer, Mr. Shaw, had cumulative targets of 100% of their individual base salaries, and its Chief Financial Officer, Mr. McFall, had a cumulative target of 80% of his individual base salary, which were, in each case, the same position level salary targets applicable in 2019. The Board sets performance target achievement levels for its executives that are challenging enough to require strong and consistent effort by the executives to be achieved and such that the Company's actual performance above projections would result in payouts above target levels and would likely also result in an increase in total shareholder value. Over the last five years, annual incentive payouts under the executive incentive compensation plan have been below target one time and exceeded target four times, ranging from 15% to 516% of target during this period of time, and over that same period, the value of the Company's stock, and associated shareholder value, increased 79%.

The performance metrics, weighting, targets, actual results and achievement levels utilized by the Compensation Committee for calculating the incentive compensation payable to each of the NEOs for the year ended December 31, 2020, are identified in the table below:

David O'Reilly and Greg Henslee, in consultation with the Compensation Committee, have elected to exclude themselves from participation in the annual cash incentive compensation plan pursuant to their responsibilities of providing strategic direction and guidance to the Company and their more limited role in the Company's day-to-day operational activities.

Long-term, stock-based incentives

The Company offers long-term incentives for executive officers and management in the form of stock option and restricted stock awards. Stock options and restricted stock may be awarded to the Company's NEOs, upper- and middle-managers and other key personnel.

The Company believes that its stock-based incentive award programs are an important component of compensation as an incentive for long-term corporate performance. The Compensation Committee has determined that the annual award of restricted stock or grant of stock options to the Company's executive officers is a key component of each executive officer's total compensation package based on his duties. The amounts of such restricted stock awards and/or stock option grants are determined by the Compensation Committee annually in conjunction with performance reviews and salary adjustments during the January Compensation Committee meeting. In determining whether and how many restricted stock awards and/or stock options should be granted, the Compensation Committee considers the responsibilities and seniority of each of the executive officers, as well as the Company's financial performance and other factors as it deems appropriate, consistent with its compensation philosophy and policies. The restricted stock awards and stock options awarded by the Compensation Committee in 2020, as reflected in the "Grants of Plan Based Awards" table, include an annual award of restricted stock or grant of stock options, as the case may be, determined by the Compensation Committee in consideration of the factors described above.

In the past, the Compensation Committee has reviewed and considered using other equity-based incentives for the long-term compensation component. After a thorough analysis, including an analysis of the equity grant practices of our peer group companies, stock options and restricted stock awards were determined to be the most effective methods of aligning management interests with those of the Company's shareholders.

The Compensation Committee has also established specific stock option awards to be granted upon the achievement of certain defined positions of employment. These are automatic grants that occur on the date of promotion or appointment to such positions with an option price equal to the closing market value of the common stock underlying the option on such date. It is the Company's belief that these position-related grants provide an additional incentive to its executives, management and other Team Members to set personallong-term employment goals. In furtherance of this belief, the Company also has a Team Member stock purchase plan that enables Team Members to purchase its common stock at a discount through payroll deductions, and Team Members are also able to invest in the Company's common stock through its 401(k) plan. In addition, the Compensation Committee may grant stock option awards in connection with a material business event, such as a large acquisition. The Compensation Committee believes that these special stock option awards provide an additional incentive to the Company's executive officers, management and other Team Members to ensure these material acquisitions are integrated effectively and efficiently.

Other

The Company sponsors a 401(k) Profit Sharing and Savings Plan (the "401(k) Plan") that allows Team Members to make plan contributions on a pre-tax basis. The Company matches 100% of the first 2% of the Team Member's compensation, and 25% of the next 4% of the Team Member's compensation.

Although executives are eligible to participate in the 401(k) Plan, the application of the annual limitations on contributions under Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (the "Code") prevents highly compensated employees, as defined by the Code, from participating at the same levels as non-highly compensated employees. The Company has established the O'Reilly Automotive Deferred Compensation Plan (the "Deferred Compensation Plan"), which is intended to restore contributions lost because of the application of the annual limitations under the Code that are applicable to the 401(k) Plan. The Deferred Compensation Plan provides executives who participate in the 401(k) Plan with the opportunity to defer the full 6% of covered compensation by making contributions to the Deferred Compensation Plan that are then matched by the Company as if they had been made under the 401(k) Plan. This benefit, which assists executives in accumulating funds for retirement, is consistent with observed competitive practices of similarly situated companies.

Section 162(m) ("Section 162(m)") of the Code generally disallows a tax deduction to publicly held companies for compensation paid to certain executive officers, to the extent that compensation exceeds $1 million per officer in any year. The Compensation Committee believes that in establishing the cash and equity incentive compensation programs for the Company's executive officers, the potential deductibility of the compensation payable under those programs should be only one of a number of relevant factors taken into consideration, and not the sole governing factor. Accordingly, the Compensation Committee may provide one or more executive officers with the opportunity to earn base and incentive compensation, whether through base salary, cash incentive based compensation programs tied to the Company's financial performance or share-based awards in the form of restricted stock or stock options, which may be in excess of the amount deductible by reason of Section 162(m) or other provisions of the Code. The Company believes it is important to maintain incentive compensation at the requisite level to attract and retain the executive officers essential to the Company's financial success, even if all or part of that compensation may not be deductible by reason of the Section 162(m) limitation.

In addition, the Company provides its executive officers with certain perquisites, which the Compensation Committee believes are reasonable and consistent with the objectives of attracting and retaining superior Team Members, as well as maintaining a competitive total compensation package for the executive officers. Perquisites can include personal use of a Company automobile, personal use of the Company plane, reimbursement for health and country club memberships and reimbursements under the Company's executive management medical reimbursement benefit plan. Perquisite amounts for the Company's NEOs are included in the "Summary Compensation Table" in the column "All Other Compensation."

The Company has entered into change in control severance agreements with its NEOs. These are described in the "Potential Payments on Termination or Change in Control" and "Employment Arrangements with Executive Officers" sections of the narrative disclosure to the "Summary Compensation Table."

Clawback policy

The Board is dedicated to maintaining and enhancing a culture that is focused on integrity and accountability while tying compensation to the Company's performance. The Board, following a recommendation by the Compensation Committee, adopted an incentive compensation clawback policy (the "Policy") in 2014. Each of the Company's NEOs has signed an acknowledgement agreeing to comply with the provisions of the Policy. The Policy is intended to provide an appropriate and effective incentive compensation recoupment program and to offer a balanced approach to aligning the interests of the Company's NEOs and shareholders.

The adopted Policy specifically provides that if the Board or the Compensation Committee determines that incentive compensation of a current or former NEO was overpaid as a result of a restatement of the reported financial results of the Company due to material non-compliance with financial reporting requirements that resulted from the fraud or willful misconduct of the covered employee, then the Board or the Compensation Committee will review the incentive compensation paid, granted, vested or accrued based on the prior inaccurate results. The Policy also provides that, to the extent practicable and as permitted by applicable law, the Board or Compensation Committee will determine whether to seek to recover or cancel the difference between any incentive compensation that was based on having met or exceeded performance targets that would not otherwise have been met based upon accurate financial data and the incentive compensation that would have been paid or granted or that would have vested had the actual payment, granting or vesting been calculated based on the accurate data or restated results, as applicable.

The Policy applies to all incentive compensation granted, paid or credited after the Policy's adoption by the Board, except to the extent prohibited by applicable law or any other legal obligation of the Company. "Incentive compensation" means performance bonuses and incentive awards (including stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares or other stock-based awards) paid, granted, vested or accrued under any Company plan or agreement in the form of cash or Company common stock.

Prohibition on Pledging and Hedging Company Securities

The Company's Insider Trading Policy specifically prohibits Directors and Named Executive Officers from hedging or pledging Company securities. These covered persons may not enter into hedging or monetization transactions with respect to Company securities and they cannot hold Company securities in a margin account or pledge Company securities as collateral for a loan. The Board believes this policy further ensures that the interests of these covered persons will remain aligned with those of the Company's security holders and these individuals will continue to be incentivized to execute the Company's long-term plans and achieve the performance for which their equity awards are intended.

• (a) The "Salary" column includes the portion of salary deferred at a NEO's election under the Company's 401(k) Plan and/or Deferred Compensation Plan.

• (b) The "Stock Awards" column refers to restricted share awards granted in 2020, 2019 and 2018, as further discussed in the "Long-term, stock-based incentives" section of the "Compensation Discussion and Analysis" portion of this proxy statement. All restricted shares awarded vest annually in equal installments over a three-year period, commencing on the first anniversary of the award, subject to the executive's continued service through each vesting date. The dollar value of stock awards represents the grant-date fair value of the awards based on the closing market price of the Company's common stock on the grant date of the award. Please see Note 13 "Share-Based Compensation and Benefit Plans" to the Company's Consolidated Financial Statements included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2020, for further discussion of the accounting used in calculating share-based compensation expenses in accordance with ASC 718.

• (c) The "Option Awards" column refers to the option awards granted to the NEOs, which become exercisable with respect to 25% of the covered shares one year from the date of grant; 50% exercisable two years from the date of grant; 75% exercisable three years from the date of grant and the remainder become exercisable four years from the date of grant. The amounts recognized in the above table reflect the grant date fair value of stock option awards granted during 2020, 2019 and 2018. During the fiscal years ended December 31, 2020, 2019 and 2018, no option awards were forfeited by the named executives. The grant date fair value of option awards was determined using the Black-Scholes option-pricing model. The Black-Scholes model requires the use of assumptions, including expected volatility, expected life, the risk free rate and the expected dividend yield. Please see Note 13 "Share-Based Compensation and Benefit Plans" to the Company's Consolidated Financial Statements included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2020, for further discussion of these assumptions and the accounting used in calculating share-based compensation expenses in accordance with ASC 718.

• (d) The "Non-Equity Incentive Plan Compensation" column refers to the cash payouts under the Company's annual performance incentive plan, which is paid in the year following the plan year. A detailed description of the annual performance incentive plan can be found in the "Incentive compensation plan" section of the "Compensation Discussion and Analysis" portion of this proxy statement.

• (a) All NEO contribution amounts have been included in the "Salary" column of the "Summary Compensation Table."

• (b) All registrant contributions have been included in the "All Other Compensation" column of the "Summary Compensation Table." NEOs must be employed on December 31 to receive that year's Company matching contribution, with the matching Contribution funded annually at the beginning of the year following the year in which the matching contribution was earned. At the beginning of 2021, Company matching contributions of $22,050, $19,500, $36,346, $46,943, and $44,753 were contributed for David O'Reilly, Greg Henslee, Gregory D. Johnson, Jeff M. Shaw, and Tom McFall, respectively, for the fiscal year ended December 31, 2020.

• (c) Amounts included in the "Aggregate Earnings in Last Fiscal Year" column are not reported as compensation in the "Summary Compensation Table" because the Company does not pay guaranteed, above-market or preferential earnings on deferred compensation under the Deferred Compensation Plan.

The Deferred Compensation Plan provides executive officers who participate in the 401(k) Plan with the opportunity to defer the full 6% of covered compensation, including salary and incentive based compensation, by making contributions to the Deferred Compensation Plan that are then matched by the Company as if they had been made under the 401(k) Plan. The Deferred Compensation Plan is intended to restore contributions lost because of the application of the annual limitations under the Code that are applicable to the 401(k) Plan. Executive officers may elect to defer their base compensation, incentive compensation and/or bonuses to the Deferred Compensation Plan. Executive officers can elect to allocate their contributions, as well as the Company matching contributions, to various equity, bond or fixed income funds, or a combination thereof, and all interest and/or earnings, which may be credited to the executive officer's account, are based on the applicable fund's market performance. Executive officers may elect to receive distributions at retirement or starting in a specific future year before or after anticipated retirement and may elect to receive the distribution in a lump sum or in periodic payments.

CEO Pay Ratio

Pursuant to Item 402(u) of Regulation S-K and Section 953(b) of the Dodd-Frank Act (the "Rule"), presented below is the ratio of annual total compensation of the Company's Chief Executive Officer, Greg D. Johnson, to the annual total compensation of the Company's median employee (excluding the Chief Executive Officer). The ratio presented below is a reasonable estimate calculated in a manner consistent with Item 402(u).

To determine the median employee in 2020, the Company calculated the annual total cash compensation of each employee for the year ended December 31, 2020. Total cash compensation for this purpose included base salary, bonus and commissions compiled from the Company's payroll data. For employees who were hired during the year, but did not work the full year, their compensation was annualized, but no cost-of-living adjustments were made. Independent contractors or leased workers were not included in the employee population. For 2020, the Company used a new median employee, identified as described above, for purposes of the ratio calculation, as its 2019 median employee was no longer with the Company. The Company used the same measurement date of December 31, as it used in the previous year to determine its median employee. No cost-of-living adjustments were applied as part of the calculation. Employees in Mexico were excluded from the total employee population under the Rule's allowed de minimis exemption, as these 1,397 employees accounted for less than 5% of the Company's total employee population of 77,654 as of December 31, 2020. For 2020, the employee population for the ratio calculation consisted of 75,764 full-time, part-time and seasonal workers who were employed in the United Sates as of December 31, 2020.

Annual total compensation, as determined under the Rule, for the Company's Chief Executive Officer was $8,990,958 for the year ended December 31, 2020, see "Summary Compensation Table" for details. Annual total compensation, as determined under the Rule, for the Company's median employee was $25,958 for the year ended December 31, 2020. The ratio of the Company's Chief Executive Officer's annual total compensation to its median employee's total compensation is 346 to 1 for the year ended December 31, 2020.

Potential Payments on Termination or Change in Control

Change in Control Agreements

The Company has entered into change in control severance agreements ("the CIC Agreements") with its NEOs, which become effective only upon a Change in Control (as defined in the CIC Agreements). In addition, under the Company's incentive plans there is acceleration of vesting with respect to stock options and restricted stock awards upon a Change in Control (as defined in the applicable incentive plan).

Pursuant to the terms of the CIC Agreements, if, within six months prior to or two years following a Change in Control, any of the NEOs' employment is terminated by the Company without "Cause," by reason of death or "Disability," or by the NEO for "Good Reason" (each, as defined in the CIC Agreements), then, subject to the NEO's execution of a release of claims and compliance with their CIC Agreement the NEO will be entitled to

• • continuation of salary for two years and a payment equal to two times the NEO's target bonus;

• • continuation of insurance coverage for two years;

• • any unpaid bonus for the immediately preceding year and a pro rata target bonus for the year of termination;

• • an amount equal to all earned but unused vacation days;

• • payment for outplacement services, up to $30,000 and not to exceed 24 months;

• • immediate vesting for all equity-based awards and immediate exercisability for 12 months for all outstanding stock options; and

• • all reasonable legal fees and expenses incurred in disputing the termination of the executive's employment.

The following table shows the amounts that those NEOs who have entered into CIC Agreements would have received if their employment had been terminated by the Company without Cause, be reason of death or Disability, or by the NEO for Good Reason immediately following a Change in Control on December 31, 2020. The unvested stock option grants and unvested restricted share awards vest pursuant to the terms of the incentive plans upon a Change in Control irrespective of a termination of employment. This table does not include amounts related to the NEOs' vested benefits under the Deferred Compensation Plan, pursuant to stock option grants or restricted share awards or other compensation, which are described in the tables above.

Employment Arrangements with Executive Officers

The Company entered into a written employment agreement effective January 1, 1993, with David O'Reilly. Such agreement provides for Mr. O'Reilly to be employed by the Company for a minimum period of three years and automatically renews for each calendar year thereafter. As compensation for services rendered to the Company, the agreement provides for Mr. O'Reilly to receive (i) a base annual salary adjusted annually; and (ii) a bonus, the amount of which is determined by reference to such criteria as may be established by the Compensation Committee. Mr. O'Reilly, in consultation with the Compensation Committee, has elected to exclude himself from participating in the bonus portion of his employment agreement pursuant to his responsibilities of providing strategic direction and guidance to the company and his more limited role in the Company's day-to-day operational activities.

Mr. O'Reilly's employment may be terminated by the Company for cause (as defined in the agreement) or without cause. If Mr. O'Reilly's employment is terminated for cause or if Mr. O'Reilly resigns, his salary and bonus rights will cease on the date of such termination or resignation. If the Company terminates Mr. O'Reilly without cause, all compensation payments will continue through the remainder of the agreement's term. Pursuant to this agreement, Mr. O'Reilly has agreed, for so long as he is receiving payments thereunder, to adhere to certain confidentiality obligations and refrain from engaging, directly or indirectly, in any automotive parts distribution, manufacturing or sales business in the states in which the Company operates without prior written consent of the Company. If Mr. O'Reilly had terminated employment on December 31, 2020, such payments would have totaled approximately $735,000.

The Company entered into a written retirement agreement effective December 29, 1997, as amended on February 1, 2001, with David O'Reilly. Such agreement, as amended, provides for supplemental retirement benefits for a period of ten years beginning with the date of Mr. O'Reilly's retirement. Benefits under the agreement include an annual salary, adjusted annually for inflation, full participation in the Company's health insurance program, full participation in the Company's medical reimbursement plan for senior management, use and maintenance of a Company vehicle and premiums for split-dollar life insurance. Pursuant to this agreement, Mr. O'Reilly has agreed, for so long as he is receiving payments thereunder, to adhere to certain confidentiality obligations and refrain from engaging, directly or indirectly, in any automotive parts distribution, manufacturing or sales business in the states in which the Company operates without prior written consent of the Company. If Mr. O'Reilly had retired from the Company on December 31, 2020, his first year annual salary payment would have totaled approximately $213,000, and his other benefits under this agreement for the first year would have totaled approximately $24,000.

Director Compensation

Please see the "Compensation of Directors" section of this proxy statement for a discussion of the manner in which the Company's directors are compensated.

Certain Relationships and Related Transactions

The Company leases certain land and buildings related to 69 of its O'Reilly Auto Parts stores and one surplus property under fifteen-and twenty-year operating lease agreements with entities in which David O'Reilly, Larry O'Reilly and Rosalie O'Reilly Wooten, who retired from the Board effective May 14, 2020, or members of their families, are affiliated. In addition, the Company leases certain land and buildings related to two of its O'Reilly Auto Parts stores under fifteen-year operating lease agreements with Greg Henslee. Generally, these lease agreements provide for renewal options for an additional five years at the option of the Company and the leaseagreements are periodically modified to further extend the lease term for specific stores under the agreements. The total aggregate lease payments paid by the Company to the entities and individuals above was $4.7 million for the year ended December 31, 2020. The Company believes that the terms and conditions of the transactions with affiliates described above were no less favorable to the Company than those that would have been available to the Company in comparable transactions with unaffiliated parties.

Approval or ratification of transactions with related persons

Pursuant to the terms of the Audit Committee Charter, the Audit Committee is responsible for reviewing and approving all proposed transactions between the Company, any of the Company's Officers or Directors, or relatives or affiliates of any such Officers or Directors, to ensure that such related party transactions are on a similar economic basis as a like transaction that occurred at arm's length with an independent third party and are in the Company's overall best interest and in the best interest of the Company's shareholders. The quarterly Audit Committee meeting includes a standing agenda item for the review of such related party transactions. The Audit Committee has not adopted any specific procedures for the conduct of the reviews, rather each transaction is considered in light of the individual facts and circumstances. In the course of its review and approval of a transaction, the Audit Committee considers the following, among other factors it deems appropriate:

• • whether the transaction is fair and reasonable to the Company;

• • the business reasons for the transaction;

• • whether the transaction would impair the independence of one or more of the Company's Officers or Directors; and

• • whether the transaction is material, taking into account the significance of the transaction.

During 2020, all related party transactions were reviewed in accordance with the above procedures.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires the Company's executive officers and Directors, and persons who own more than 10% of a registered class of the Company's equity securities, to file reports of ownership and changes in ownership with the SEC. Such individuals are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file. To the Company's knowledge, based solely on its review of the copies of such forms furnished to it and written representations with respect to the timely filing of all reports required to be filed, it believes that such persons complied with all Section 16(a) filing requirements applicable to them with respect to transactions for the year ended December 31, 2020, except for one late Form 4 filing made on behalf of Larry O'Reilly reporting a transaction on March 20, 2020.

AUDIT COMMITTEE REPORT

The Audit Committee functions pursuant to a written charter, which may be viewed on the Company's website atwww.OReillyAuto.com. In compliance with that charter and in connection with the December 31, 2020, financial statements, the Audit Committee

• • reviewed and discussed with management the Company's audited financial statements as of, and for the year ended, December 31, 2020;

• • discussed with the Company's independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC; and

• • received from the independent auditors the written disclosures and the letter regarding the auditor's independence required by the applicable requirements of the PCAOB and has discussed with the independent auditors their independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements referred to above be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

PROPOSAL 2 - ADVISORY VOTE ON EXECUTIVE COMPENSATION

Pursuant to Section 14A of the Exchange Act, the Company is required to provide shareholders with an opportunity to vote, on an advisory (non-binding) basis, to approve the compensation of its NEOs. This proposal is commonly referred to as a "Say-on-Pay" proposal. As required by these rules, the Company is asking you to vote FOR the adoption of the following resolution:

"Resolved, that the compensation paid to the Company's NEOs, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K of the Securities Exchange Act of 1934, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED."

In considering their vote, shareholders should review the Company's compensation of its NEOs in the "Compensation Discussion and Analysis" ("CD&A") section herein and Compensation Committee report included in these proxy materials. As described in the CD&A, the Company's executive officer compensation programs are designed around the following elements:

• • recruiting and retaining qualified Team Members,

• • the career development and progression of the Company's Team Members, and

• • observed industry practices.

The main objective of the Company's compensation philosophy is to provide its executive officers and management with a total compensation package that is competitive and equitable and that encourages and rewards performance based in part upon the Company's performance in terms of increases in share value. The Company believes that aligning the interests of its executives and management with those of its shareholders further promotes the success of not only the Company, but also its Team Members. The Company's executive compensation policies are focused upon both short-term and long-term incentives and goals. The Company believes that such policies do not create incentives for inappropriate individual or collective risk taking. The Company also believes that the current programs do not create any incentives with respect to individual or collective behavior that are likely to have a material adverse effect upon either its risk profile or overall approach to risk management.

The Company also has adopted an incentive compensation clawback policy and entered into change in control agreements with the Company's executives that do not contain excise tax gross-up provisions, as described in more detail above under the description "Clawback policy" and under the description "Potential Payments on Termination or Change in Control" in this proxy statement.

As this vote is advisory in nature, this proposal does not bind the Company to any specific course of action. However, the Compensation Committee, which is responsible for designing and implementing its executive compensation packages, values the opinions expressed by the Company's shareholders in this vote and will consider the outcome of the vote when making decisions on future executive compensation packages.

Although this vote is advisory in nature and does not impose any action on the Company or the Compensation Committee of the Board, the Company strongly encourages all shareholders to vote on this matter.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF THE COMPANY'S

EXECUTIVE OFFICER COMPENSATION AS DESCRIBED IN THIS PROXY STATEMENT.

PROPOSAL 3 - RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Audit Committee is directly responsible for the appointment, compensation, retention, evaluation and oversight of the Company's independent registered public accounting firm retained to audit the Company's financial statements. As part of this responsibility, the Audit Committee considers the firm's independence, qualifications, performance, and whether the independent registered public accounting firm should be rotated, as well as the impact of such a rotation. The Audit Committee is also involved in the selection and approval of the Lead Audit Partner who, in compliance with Sarbanes-Oxley requirements, rotates every five years. The last Lead Audit Partner rotation occurred in 2020. Pursuant to these requirements, the Company will have a new Lead Audit Partner in 2025.

At the Annual Meeting of Shareholders held on May 14, 2020, the Company's shareholders ratified the selection of Ernst & Young ("E&Y") as the Company's independent auditors for the year ending December 31, 2020.

It is the Audit Committee's policy that the Company's independent auditors be engaged to provide primarily audit and audit-related services. However, pursuant to the policy, in certain circumstances and using stringent standards in its evaluation, the Audit Committee may authorize the Company's independent auditors to provide tax or other non-audit related services when it determines that the Company's independent auditors will be the most efficient and effective service provider.

The Audit Committee has adopted a policy that requires advance approval of all audit, audit-related, tax and other services performed by the independent auditor. The policy provides for preapproval by the Audit Committee of specifically defined audit and non-audit services. Unless the specific service has been previously approved with respect to that year, the Audit Committee must approve the permitted service before the independent auditor is engaged to perform it. The Audit Committee has delegated to the Chair of the Audit Committee authority to approve permitted services, provided that the Chair reports any decisions to the Committee at its next scheduled meeting. Each year prior to engaging the Company's independent auditor, the Company submits to the Audit Committee for approval a list of services expected to be provided during that fiscal year within each of the three categories of services described below, as well as related estimated fees, which are generally based on time and materials.

All services provided by the Company's independent auditor during 2020 were preapproved in accordance with this policy.

The Audit Committee, after review and discussion with the Company's independent auditor of the preceding information, determined that the provision of these services was compatible with maintaining the Company's independent auditor's independence.

Fees Paid to Independent Registered Public Accounting Firm

The following table summarizes the fees billed by E&Y for audit and other professional services during the years ended December 31, 2020 and 2019:

• (b) Consists of fees and expenses billed for the annual audit of the Company's employee benefit plans.

• (c) Consists of fees and expenses billed for tax advisory services, including compliance, planning and advice.

The Audit Committee of the Board has selected Ernst & Young LLP ("E&Y"), as the Company's independent auditors for the year ending December 31, 2021, and has further directed that management submit the selection of independent auditors for ratification by the shareholders at the Annual Meeting. E&Y has audited the Company's financial statements since 1992. Representatives of E&Y are expected to be present at the Annual Meeting. They will have an opportunity to make a statement, if they so desire, and will be available to respond to appropriate questions.

None of the Company's Bylaws, other governing documents, Missouri or federal law, or The Nasdaq Global Select Market Listing Qualifications requires shareholder ratification of the selection of E&Y as the Company's independent auditors. However, the Audit Committee is submitting the selection of E&Y to the shareholders for ratification as a matter of good corporate practice. If theshareholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of different independent auditors at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company and its shareholders.

PROPOSAL 4 - SHAREHOLDER PROPOSAL ENTITLED "IMPROVE OUR CATCH-22 PROXY ACCESS"

The Company has been advised that Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, CA 90278, who has indicated he is a beneficial owner of no fewer than 25 shares of the Company's common stock, intends to submit the following proposal at the Annual Meeting:

"Shareholders request that our board of directors take the steps necessary to enable as many shareholders as may be needed to combine their shares to equal 3% of our stock owned continuously for 3-years in order to enable shareholder proxy access.

The current arbitrary ration of 20 shareholders to initiate shareholder proxy access can be called Catch-22 Proxy Access. In order to assemble a group of 20 shareholders, who have owned 3% of O'Reilly Automotive stock for an unbroken 3-years, one would reasonably need to start with 60 activist shareholders who own 9% of ORLY stock for an unbroken 3-years because initiating proxy access is a complicated process that is easily susceptible to errors and is also highly susceptible to dropouts.

The 60 activist shareholders could then be whittled down to 40 shareholders because some shareholders would be unable to timely meet all the paper chase requirements. After the 40 shareholders submit their paperwork to management - then management might arbitrarily claim that 10 shareholders do not meet the requirements (figuring that shareholders do not want a battle in court) and management might convince another 10 shareholders to drop out-leaving 20 shareholders. But the current bylaws do not allow 40 shareholders to submit their paperwork to management to end up with 20 qualified shareholders.

And 60 shareholders who own 9% of company stock for an unbroken 3-years might determine that they own 51 % of company stock when length of stock ownership is factored out. Thus a shareholder proxy access right would be moot.

But how does one begin to assemble a group of 60 potential participants if potential participants cannot even be guaranteed participant status after following the tedious rules that are 4300-words of legalese - because a single shareholder always takes the risk that one will be the 21st shareholder who could be voted off the island after a substantial investment of time by the arbitrary ration of 20 shareholders.

The current arbitrary ration of 20 shareholders to initiate shareholder proxy access means that shareholders of the same class of stock are treated unequally. At least one court concluded that a company cannot provide different voting rights for the owners of the same class of stock.

More emphasis should be given to improving shareholder proxy access because we do not have the right to act by written consent due to backward provisions of Missouri law. Also the shareholder right to call a special meeting has taken a big hit due to the avalanche of online shareholder meetings that can be tightly controlled bare bones meetings where all challenging questions and comments can be screened out by management. This has paved the way for a future special shareholder meeting to be a bare bones online meeting.

Please vote yes:

Improve Our Catch-22 Proxy Access - Proposal 4"

The Company's Statement in Opposition to Proposal 4:

The Board recommends a vote AGAINST proposal 4, as the Board believes the proposal is unnecessary and not in the best interests of the shareholders.

The Company's proxy access provisions are consistent with current market standards and best practices.

Under our existing proxy access bylaw, a shareholder or group of up to and including 20 shareholders who own at least 3% of the Company's outstanding common stock continuously for three years may nominate candidates representing 20% of the Board (with a minimum of 2 nominees), and include those nominees in the Company's proxy materials, provided that the shareholders and the nominees satisfy the requirements specified in the Bylaws. Prior to adopting our proxy access bylaw, the Board carefully evaluated various terms concerning ownership thresholds, holding periods, the cap on board seats and aggregation limits among other factors. In addition, the Board considered existing shareholder rights, investors' views, other companies' proxy access bylaws and the Company's institutional investor profile. The terms of our proxy access bylaw remain consistent with the vast majority of proxy access bylaws adopted to date, and the 20-shareholder aggregation limit has been adopted by more than 90% of the companies with proxy access.

Our proxy access bylaw strikes the appropriate balance between promoting shareholder rights and protecting the interests of all shareholders.

Based on the Board's assessment of the factors detailed above and our ongoing shareholder engagement, we continue to believe that our current form of proxy access, including the current group aggregation limit of 20 shareholders, reflects best practice and strikes the appropriate balance between enhancing shareholder rights and protecting the interests of all of our shareholders.

When a group of shareholders submits a director nominee through the proxy access right, the Company is responsible for verifying that each shareholder in the group has met all procedural requirements and that each shareholder will continue to meet these requirements through the annual meeting. The aggregation limit, set at a reasonable and market standard of 20 shareholders, helps ensure that the Company will not be overburdened by the administrative confirmation process for a potentially large number of shareholders. Undertaking this process for a large group of shareholders likely would cost the Company significant time and resources, diverting them away from primary business functions and impeding the exercise of proxy rights by other shareholders. In addition, the aggregation limit prevents the abuse of proxy access by a group of shareholders that do not have a substantial economic stake in the Company or who may have special or short-term interests and who are not able to gain a threshold level of support.

The Company has demonstrated an ongoing commitment to corporate governance best practices.

The Board has carefully considered evolving corporate governance practices and has adopted policies and practices that ensure shareholders have significant rights and protections. In this respect, our corporate governance program includes the following best practices:

• • The opportunity to elect directors annually using a majority voting standard;

• • The ability to recommend director candidates to the Corporate Governance/Nominating Committee, which considers those recommendations in the same manner as recommendations received from other sources;

• • The option to directly nominate director candidates and solicit proxies for the election of those candidates in accordance with the Bylaws and the federal securities laws;

• • The right to submit proposals for inclusion in the Company's proxy statement for consideration at an annual meeting, subject to the rules and regulations of the SEC;

• • The opportunity to vote annually in the "say-on-pay" vote to express their views on executive compensation; and

• • The right for shareholders to call special meetings.

More information about our governance practices is described in the "Information Concerning the Board of Directors" portion of this proxy statement.

The Company has a proxy access bylaw that strikes the appropriate balance between enhancing shareholder rights and protecting and serving the best interests of all of our shareholders. The Company also has consistently demonstrated responsiveness to shareholders and maintains best practice corporate governance policies and practices. Accordingly, the modification requested by the proposal to our existing proxy access bylaw would not enhance shareholder value and is not in the best interests of the Company and all of its shareholders.

Recommendation of the Board:

For the foregoing reasons, the Board of Directors recommends that you vote "AGAINST" proposal 4 to amend our proxy access bylaw. As with all proposals, if the proposal is not properly presented by the proponent at the Annual Meeting, it will not be voted upon.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "AGAINST" THE SHAREHOLDER PROPOSAL

ENTITLED "IMPROVE OUR CATCH-22 PROXY ACCESS."
