Quorum and Voting Procedures

Quorum Requirement

A quorum of stockholders is necessary to hold a valid meeting. The presence, in person or by proxy, of the holders of a majority of the total voting power of all outstanding securities of the Company entitled to vote at a meeting of stockholders shall constitute a quorum. Abstentions and “broker non-votes” are counted as present for establishing a quorum. A “broker non-vote” occurs on a proposal when shares held by brokers or nominees as to which instructions have not been received from the beneficial owners or persons entitled to vote and that the broker or nominee does not have discretionary power to vote on a non-routine matter.

Vote Necessary to Approve Proposals

General

Votes cast by proxy or in person at the meeting will be counted by the persons appointed by the Company to act as Judges of Election for the meeting. The Judges of Election will treat shares represented by proxies that reflect abstentions as shares that are present and entitled to vote for purposes of determining the outcome of any other business submitted at the meeting to the stockholders for a vote.

Your proxy will be voted at the meeting, unless you (i) revoke it at any time before the vote by filing a revocation with the Secretary of the Company, (ii) duly execute a proxy card bearing a later date, or (iii) appear at the meeting and vote in person. Proxies returned to the Company, votes cast other than in person and written revocations will be disqualified if received after commencement of the meeting. If you elect to vote your proxy by telephone or internet as described in the telephone/internet voting instructions on your proxy card, the Company will vote your shares as you direct. Your telephone/internet vote authorizes the named proxies to vote your shares in the same manner as if you had marked, signed and returned your proxy card.

Proposal 1 – Election of Three Class II Directors Whose Current Terms Expire on the Date of the 2015 Annual Meeting

The Class II directors shall be elected by a plurality of the votes cast at the Annual Meeting so long as a quorum is present. Under this stan-

dard, you may either vote in favor of all Class II directors, or withhold on all Class II directors or a particular Class II director. If you do not vote at all, you will have no impact on the calculation of “votes cast.” “Broker non-votes” will not count as a vote cast and will likewise have no effect. Unless specification to the contrary is made, the shares represented by the enclosed proxy will be voted FOR all the director nominees.

All Other Proposals

For Proposals 2 and 3, the affirmative vote of a majority of the shares of our capital stock present in person or represented by proxy at the Annual Meeting and entitled to vote is required for approval. You may vote “for,” “against” or “abstain” on these matters. If you vote to “abstain,” it will have the same effect as a vote “against.” “Broker non-votes” are not counted as shares present or represented and voting and have no effect on the vote. Unless specification to the contrary is made, the shares represented by the enclosed proxy will be voted FOR the approval of the compensation of the Named Executive Officers, as disclosed in this proxy statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission (on an advisory, non-binding basis) and FOR approval of the action of the Audit Committee of the Board of Directors in appointing KPMG LLP as the Company’s independent registered public accounting firm for 2015.

Broker Voting

If your shares are held in the name of a bank, broker or other holder of record (a “nominee”), you will receive instructions from the nominee that you must follow in order for your shares to be voted. Certain of these institutions offer telephone and Internet voting. Under current New York Stock Exchange (“NYSE”) rules, the proposal to ratify the appointment of KPMG LLP as the Company’s independent registered public accounting firm for the current fiscal year should be considered a routine matter. However, for purposes of determining the outcome of any non-routine matter as to which the broker does not have discretionary authority to vote, those shares will be treated as not present and not entitled to vote with respect to that matter. Notably, Proposals 1 and 2 should be considered non-routine matters and your broker is not permitted to vote your shares without your instructions and such uninstructed shares are considered “broker non-votes.”

Voting Securities

On March 10, 2015, the record date for the meeting, the Company had 45,538,520 shares of common stock outstanding, all of one class and each share having one vote with respect to all matters to be voted on at the meeting. Information as to common stock ownership of certain beneficial owners and management is set forth in the tables under “Security Ownership of Certain Beneficial Owners” and “Security Ownership of Directors and Management” included on page 14 in this Proxy Statement.

The Board recognizes that it is important for the Company’s directors to possess a diverse array of backgrounds and skills, whether in terms of executive management leadership, public company experience or educational achievement. When considering new candidates, the Nominating and Governance Committee, with input from the Board, will seek to ensure the Board reflects a range of talents, ages, skills, diversity and expertise, particularly in the areas of accounting and finance, management, government/regulation, leadership and convenience store and other retail-related industries, sufficient to provide sound and prudent guidance with respect to our operations and interests. In addition, although it does not have a separate policy with respect to diversity, the Nominating and Governance Committee considers the issue of diversity among the factors used to identify nominees for directors. The goal is to assemble and maintain a Board comprised of individuals that not only possess a high level of business acumen, but who also demonstrate a commitment to the Company’s Code of Business Conduct and Ethics in carrying out the Board’s responsibilities with respect to oversight of the Company’s operations.

The Company’s Corporate Governance Guidelines provide that directors should not be nominated for election to the Board after their 76th birthday, although the full Board may nominate candidates older than 76 under special circumstances.

To the extent authorized by the proxies, the shares represented by the proxies will be voted in favor of the election of the three nominees for director whose names are set forth below. If for any reason any of these nominees is not a candidate when the election occurs, the shares represented by such proxies will be voted for the election of the other nominees named and may be voted for any substituted nominees or the board size may be reduced.

All directors, other than Mr. Clyde (our President and Chief Executive Officer), have been deemed independent by the Board based on the rules of the NYSE and the standards of independence included in the

Company’s Corporate Governance Guidelines. As part of its independence recommendation to the Board, the Nominating and Governance Committee at its February meeting considered familial relationships of certain directors (Mr. Murphy is a first cousin of Mr. Deming and Rev. Keller).

Mr. Murphy became the Non-Executive Chairman of the Board in connection with the spin-off of the Company from Murphy Oil Corporation (the “Spin-Off”), which was completed on August 30, 2013. As an independent chairman, he leads our regularly scheduled meetings of independent directors, held without the presence of Company management. Such meetings are scheduled to occur at four Board meetings each year.

Stockholders and other interested parties may send communications to the Board, specified individual directors and the independent directors as a group c/o the Secretary, Murphy USA Inc., 200 Peach Street, El Dorado, AR 71730-5836. All such communications will be kept confidential and forwarded to the specified director(s). Items that are unrelated to a director’s duties and responsibilities as a Board member, such as junk mail, may be excluded by the Secretary. The names of the nominees and certain information as to them, are as follows:

Director Nominees

Our Board is divided into three classes serving staggered three-year terms. Messrs. Holliger and Keyes and Ms. Landen, who are Class II directors, are nominated for re-election at this Annual Meeting of Stockholders. Class III and Class I directors will serve until our annual meetings of stockholders in 2016 and 2017, respectively. At each annual meeting of stockholders, directors will be elected for three-year terms to succeed the class of directors whose terms have expired. This section details the name, age, class, qualifications and committee memberships of our directors as of the 2015 Annual Meeting of Stockholders.

Board Leadership Structure

The positions of Chairman of the Board and Chief Executive Officer of Murphy USA are held by two individuals. Mr. Murphy serves as our Chairman of the Board as a non-executive and independent director. Mr. Clyde serves as our President and Chief Executive Officer, and also serves as a director. Along with Mr. Murphy and Mr. Clyde, other directors bring different perspectives and roles to the Company’s management, oversight and strategic development. The Company’s directors bring experience and expertise from both inside and outside the Company and industry, while the President and Chief Executive Officer is most familiar with the Company’s business and industry, most involved in the Company’s day-to-day operations, and most capable of leading the execution of the Company’s strategy. The Board believes that having separate roles of Chairman and President and Chief Executive Officer is in the best interest of stockholders because it facilitates independent oversight of management.

Risk Management

Our Company’s management is responsible for the day-to-day management of risks to the Company. The Board of Directors has broad oversight responsibility for our risk management programs.

The Board of Directors exercises risk management oversight and control both directly and indirectly, the latter through various board committees as discussed below. The Board of Directors regularly reviews information regarding the Company’s credit, liquidity and operations, including the risks associated with each. The Executive Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. The Audit Committee is responsible for oversight of financial risks and the ethical conduct of the Company’s business, including the steps the Company has taken to monitor and mitigate these risks. The Nominating and Governance Committee, in its role of reviewing and maintaining the Company’s Corporate Governance Guidelines, manages risks associated with the independence of the Board and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports and by the President and Chief Executive Officer about the known risks to the strategy and the business.

Committees

Our Board of Directors has established several standing committees in connection with the discharge of its responsibilities. The following table presents the standing committees of the Board and the current membership of such committees and the number of times each such committee met in 2014.

Audit Committee – The Audit Committee has the sole authority to appoint or replace the Company’s independent registered public accounting firm, which reports directly to the Audit Committee. The Audit Committee also assists the Board with its oversight of the integrity of the Company’s financial statements, the independent registered public accounting firm’s qualifications, independence and performance, the performance of the Company’s internal audit function, the compliance by the Company with legal and regulatory requirements, and the review of programs related to compliance with the Company’s Code of Business Conduct and Ethics. The Audit Committee meets with representatives of the independent registered public accounting firm and with members of the internal Auditing Department for these purposes. The Board has designated Mr. Taylor as its “Audit Committee Financial Expert” as defined in Item 407 of Regulation S-K. All of the members of the Audit Committee, including Mr. Taylor, are independent under the rules of the NYSE and the Company’s independence standards.

Executive Committee – The Executive Committee is vested with the authority to exercise certain functions of the board when the board is not in session. The Executive Committee is also in charge of all general administrative affairs of the Company, subject to any limitations prescribed by the board.

Executive Compensation Committee – The Executive Compensation Committee oversees the compensation of the Company’s executives and directors and administers the Company’s annual incentive compensation plan, the long-term incentive plan and the stock plan for non-employee directors.

The Executive Compensation Committee consists entirely of independent directors, each of whom meets the NYSE listing

independence standards and our Company’s independence standards. See “Compensation Discussion and Analysis” for additional information about the Executive Compensation Committee. In carrying out its duties, the Executive Compensation Committee will have direct access to outside advisors, independent compensation consultants and others to assist them.

Compensation Committee Interlocks and Insider Participation

During 2014, Messrs. Deming, Holliger, Keller, Keyes and Murphy served as the members of the Compensation Committee. No person who served as a member of the Executive Compensation Committee was, during 2014, an officer or employee of us or any of our subsidiaries, or had any relationship requiring disclosure in this proxy statement. None of our executive officers served as a member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire Board of Directors) or director of another entity, one of whose executive officers served as a member of our Board of Directors.

Nominating and Governance Committee – The Nominating and Governance Committee identifies and recommends potential director candidates, makes annual independence recommendations as to each director, recommends appointments to Board committees, oversees evaluation of the Board’s performance and reviews and assesses the Corporate Governance Guidelines of the Company. Information regarding the process for evaluating and selecting potential director candidates, including those recommended by stockholders, is set out in the Company’s Corporate Governance Guidelines. Stockholders desiring to recommend director candidates for consideration by the Nominating and Governance Committee will be able to address their recommendations to: Nominating and Governance Committee of the Board of Directors, c/o Secretary, Murphy USA, 200 Peach Street, P.O. Box 7300, El Dorado, Arkansas 71731-7300. As a matter of policy, director candidates recommended by stockholders will be evaluated on the same basis as candidates recommended by the directors, executive search firms or other sources. The Corporate Governance Guidelines also provide a mechanism by which stockholders may send communications to directors. See Proposal 1 for further detail. The Nominating and Governance Committee consists entirely of independent directors, each of whom meets the NYSE listing independence standards and the Company’s independence standards.

Charters for the Audit, Executive, Executive Compensation, Nominating and Governance Committees, along with the Corporate Governance Guidelines and the Code of Ethics and Business Conduct, are available on the Company’s Web site, http://ir.corporate.murphyusa.com.

Meetings and Attendance

During fiscal 2014, there were five meetings of the Board. All nominees’ attendance exceeded 75% of the total number of meetings of the Board and committees on which they served. As set forth in the Company’s Corporate Governance Guidelines, all Board members are expected to attend the Annual Meeting of Stockholders, and all did so in 2014.

Compensation of Directors

Directors who are employees of Murphy USA do not receive compensation for their services on the Board. Our Board of Directors determines annual retainers and other compensation for non-employee directors. The primary elements of our non-employee director compensation program include a combination of cash and equity.

In 2014, the cash component consisted of:

All retainers are paid quarterly. The Company also reimburses directors for travel, lodging, and other related expenses they incur in attending Board and committee meetings.

In addition to the cash component, the non-employee directors also receive an annual grant of time-based restricted stock units which vest after three years. Each non-employee director received a restricted stock unit grant with a target value of at $100,000 on February 12, 2014.

The column above showing “All Other Compensation” represents the incremental cost of matching gifts. The non-employee directors are eligible to participate in our matching gift program on the same terms as Murphy USA employees. Under this program, an eligible person’s total gifts of up to $12,500 per calendar year will qualify. The Company will contribute to qualified educational institutions and hospitals in an amount equal to twice the amount contributed by the eligible person. The Company will contribute to qualified welfare and cultural organizations an amount equal to the contribution made by the eligible person.

Stock Ownership Guidelines

The Board of Directors has also established stock ownership guidelines for non-employee directors of the Company. Directors are expected to achieve ownership of at least three times the annual cash retainer within five years of service. A director may not pledge Company securities either by purchasing Company securities on margin or holding Company securities in a margin account, until he or she has achieved the applicable stock ownership target specified in the guidelines above. These guidelines are designed to ensure that directors display confidence in the Company through the ownership of a significant amount of our stock. At December 31, 2014, all of our Directors had met or were on track to comply with these stock ownership guidelines within the applicable five-year period.

Review, Approval or Ratification of Transactions with Related Persons

The Nominating and Governance Committee reviews ordinary course of business transactions with firms associated with directors and nominees for director. The Company’s management also monitors such transactions on an ongoing basis. Executive officers and directors are governed by the Company’s written Code of Business Conduct and Ethics, which provides that waivers may only be granted by

the Board of Directors or a Board committee and must be promptly disclosed to stockholders. No such waivers were granted nor applied for in fiscal 2014. The Company’s Corporate Governance Guidelines require that all directors recuse themselves from any discussion or decision affecting their personal, business or professional interests.

Audit Committee Report

In connection with the Company’s December 31, 2014 consolidated financial statements, the Audit Committee reviewed and discussed the audited financial statements with management and the specific disclosures contained in the Company’s Form 10-K for the year ended December 31, 2014, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, discussed with KPMG LLP the matters required to be discussed by the communications pursuant to applicable auditing standards, and independence standards, and considered the compatibility of non-audit services with KPMG LLP’s independence. The Audit Committee has received the written disclosures and the letter from KPMG LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with that firm its independence from Murphy USA. The Committee met seven times in 2014.

Based on these reviews and discussions, the Audit Committee recommended to the Board that the Company’s audited consolidated financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2014.

The following Compensation Discussion and Analysis provides an overview of the compensation provided to our CEO, CFO, and three other most highly compensated executive officers for the year ended December 31, 2014:

In addition, we will address the compensation of John C. Rudolfs who served as our EVP, Marketing until May 21, 2014 and who would have been among our most highly compensated executive officers in 2014, other than our CEO and CFO, had he served as an executive officer of Murphy USA at the end of 2014. Mr. Rudolfs received severance benefits upon his departure, which are more fully described in the “Other Policies – Severance and Change in Control Protection” section included on page 22 in this Proxy Statement.

The six individuals above are collectively referred to herein as our “Named Executive Officers” or “NEOs”.

To further illustrate the concepts in this Compensation Discussion and Analysis, we have included charts and tables where we believe appropriate to enhance our stockholders’ understanding of the compensation of our NEOs. This Compensation Discussion and Analysis should be read in conjunction with this tabular information beginning on page 16 in this Proxy Statement.

Overview

Murphy USA operates the nation’s fourth largest convenience store chain, with 1,263 locations in 23 states as of December 31, 2014, most of which are in close proximity to Walmart stores. We believe our proximity to Walmart stores generates significant traffic to our retail stations while our competitively priced gasoline and convenience offerings appeal to our shared customers. We began our relationship with Walmart in 1996 and, in December 2012, we signed a new agreement that allows us to build approximately 200 new sites at Walmart locations over the next few years.

We operate our retail gasoline stations with a strong emphasis on fuel sales complemented by a focused convenience offering that allows for a smaller store footprint than many of our competitors. Almost all of our new stations are standardized 208 or 1,200 square foot stores and the majority of our stores are located on Company-owned property and do not incur any rent expense. This combination of a focused convenience offering and standardized smaller footprint stores allows us to achieve lower overhead and labor costs compared to our competitors with a larger store format.

2014 Business Highlights

Highlights of the Company during fiscal year 2014 include the following:

Executive Compensation Philosophy and Objectives

The Executive Compensation Committee (the “Committee”) bases its executive compensation decisions on principles designed to align the interests of our executives with those of our stockholders. The Committee believes compensation should provide a direct link with the Company’s values, objectives, business strategies, and financial results. In order to motivate, attract, and retain key executives who are critical to its long-term success, the Company aims to provide pay packages that are competitive with others in the retail industry. In addition, the Company believes that executives should be rewarded for both the short and long-term success of the Company and, conversely, be subject to a degree of downside risk in the event that the Company does not achieve its performance objectives.

We Do

We Do Not

Role of the Committee

The Committee has responsibility for discharging the Board of Directors’ responsibilities with respect to compensation of the Company’s executives. In particular, the Committee annually reviews and approves corporate goals and objectives relevant to CEO compensation, evaluates the CEO’s performance in light of those goals and objectives, and determines and approves the CEO’s compensation based on this evaluation. In doing so, the Committee reviews all elements of the CEO’s compensation. The Committee also approves non-

CEO executive compensation, approves and administers incentive compensation and equity-based plans, and monitors compliance of directors and executive officers with Company stock ownership requirements. Pursuant to its charter, the Committee has the sole authority to retain and terminate compensation consultants as well as internal and external legal, accounting and other advisors, including sole authority to approve the advisors’ fees and other engagement terms. For additional information on the responsibilities of the Committee, see the “Committees—Executive Compensation Committee” section included on page 23 in this Proxy Statement.

Role of Market Data

The Committee adopted a peer group for purposes of reviewing and approving 2014 compensation. Due to the relatively small number of publicly-traded retail convenience store competitors, the group was broadened to include other companies in similar industries with which Murphy USA competes for executive talent in order to create a sufficient sample of companies against which compensation can be compared. The peer group was developed based on certain attributes including:

The peer group consists of the following companies:

In addition to comparator company information, the Committee uses several industry compensation surveys to determine competitive market pay levels for the NEOs.

Base salaries and total target direct compensation for the Company’s NEOs were compared to the median of the market data to determine whether the Company’s compensation practices were in alignment. When making compensation-related decisions, the Committee aims to set compensation levels for executive officers based on a deliberate review of market competition for a particular position as well as each individual’s possession of a unique skill or knowledge set, proven leadership capabilities or experience, and Company performance. Based on such factors, the Committee may determine with respect to one or more individuals that it is appropriate for compensation to meet, exceed, or fall below the median of the market data for a particular compensation element or total compensation.

Role of the CEO in Compensation Decisions

The CEO periodically reviews the performance of each of the NEOs, excluding himself, develops preliminary recommendations regarding salary adjustments and annual and long-term award amounts, and provides these recommendations to the Committee. The Committee can exercise its discretion in modifying any recommendations and makes the final decisions.

A.    Base Salary

Base salary is designed to provide a competitive fixed rate of pay recognizing each employee’s different level of responsibility and performance. In setting base salary levels for NEOs, the Committee considers competitive market data in addition to other factors such as duties and responsibilities, experience, individual performance, retention concerns, internal equity considerations, Company performance, general economic conditions, and marketplace compensation trends.

Base salaries are reviewed annually. In 2014, the Committee increased base salaries awarded to each NEO to bring salaries closer to competitive market levels for similar positions. The following table shows the base salaries for each of the NEOs effective February 1, 2014:

B.    Annual Incentive Plan

We provide annual incentives to our executive officers through our stockholder-approved Murphy USA Inc. 2013 Annual Incentive Plan, as amended and restated effective as of February 12, 2014 (the “AIP”). The primary objective of the AIP is to align corporate and individual goals with stockholder interests and Company strategy and

to reward employees for their performance relative to those goals. Murphy USA targets the median of competitive market pay levels for annual target incentive compensation. Executives have the opportunity to be compensated above the median of market pay levels when Murphy USA performs above market based on established performance measures.

Bonus opportunities under the AIP are communicated as a target percentage of annualized base salary. The Committee reviews market data annually with respect to competitive pay levels and sets specific

bonus opportunities for each of our NEOs. The following table shows the target bonuses as a percentage of salary in effect for each of the NEOs in 2014:

For 2014, the AIP metrics for Murphy USA employees included return on average capital employed (“ROACE”), profitability as measured by both fuel and merchandise gross margins, and total recordable incident rate. The Committee believes these metrics in combination reflect the key goals and objectives for the Company for 2014. The

following table summarizes the performance metrics and corresponding weightings used in determining annual incentive award payouts for Murphy USA employees and the weighted performance scores for each based on actual performance during 2014:

Under the terms of the AIP, achievement of 100% of the target for any metric results in the payment of 100% of target for that metric. Achievement of the minimum level of the performance range results in the payment of 50% of target and achievement of the maximum level of performance results in the payment of 200% of target. No awards relative to a given metric are payable if performance for that metric falls below the minimum. Results between points are interpolated.

Individual Performance

In addition to the corporate performance component, the AIP permits the Committee to exercise negative discretion to reduce an NEO’s award based on the Committee’s subjective review of his/her performance relative to successful achievement of goals, business plan execution, and other qualitative results. We believe that it is important to include this component in our AIP in order to take into account NEO performance that, in the Committee’s opinion, justify a reduction in the amount otherwise payable to an NEO based on objective corporate performance. Overall, amounts earned under the AIP cannot exceed more than 200% of target. In 2014, the Committee believed that our NEOs’ outstanding individual performance was appropriately reflected in our corporate performance results. Thus, in general, the Committee opted not to make significant negative adjustments to the awards earned by our NEOs and payable under the AIP based on our corporate performance.

Overall Performance and Payouts

After certifying the results relative to our performance metrics and considering each individual’s contributions throughout the year, the Committee approved the following payments for our NEOs for 2014:

C.    Long-term Incentive Compensation

We provide share-based, long-term compensation to our executive officers through our stockholder-approved Murphy USA Inc. 2013 Long-Term Incentive Plan, as amended and restated effective as of February 12, 2014 (the “LTIP”). Long-term incentive levels for Murphy USA’s officers are targeted at the median of competitive market pay levels. The plan provides for a variety of stock and share-based awards, including stock options and restricted stock units (“RSUs”),

each of which vests over a period determined by the Committee, as well as performance stock units (“PSUs”) that are earned based on the Company’s achievement of two equally-weighted objective performance goals. We believe that these awards create a powerful link between the creation of stockholder value and executive pay delivered. In addition, we believe that the balance between absolute performance alignment through stock options and the ROACE-based PSUs, and the relative performance objectives underscored by the PSUs earned based on the Company’s TSR as compared to its peers, is appropriate. In order for executives to fully realize their targeted opportunities, Murphy USA must both successfully achieve its long-term goals and outperform its peers.

Stock Options

In 2014, stock options comprised 25% of each NEO’s annual equity award. Stock options provide a direct link between executive officer compensation and the value delivered to shareholders. The Committee believes that stock options are inherently performance-based, as option holders only realize benefits if the value of our stock increases following the date of grant. All grants of options will vest in two equal installments on the second and third anniversaries of the grant date, and unless otherwise forfeited or exercised, expire seven years from the date of the grant.

Restricted Stock Units

In 2014, RSUs comprised 25% of each NEO’s annual equity award. The Committee believes that RSUs are an important part of the compensation program for NEOs as they (i) drive behaviors to create value for shareholders by linking executive compensation to stock price performance, (ii) encourage retention, and (iii) result in actual share ownership (thereby supporting the Company’s stock ownership guidelines). All grants of RSUs will cliff-vest on the third anniversary of the grant date (unless otherwise forfeited due to termination) and are delivered to the NEOs in the form of unrestricted shares of common stock.

Performance Stock Units

In 2014, PSUs comprised 50% of each NEO’s annual equity award. The Committee believes that PSUs serve as a complement to stock options and RSUs. Our PSUs benchmark Murphy USA performance relative to two equally-weighted metrics, ROACE and TSR relative to our peer group, with payouts at the threshold level of performance equal to 50% of target and maximum payouts capped at 200% of target. The Committee believes the PSU program does not encourage excessive or inappropriate risk-taking, as it caps the maximum payout at 200% of target. PSUs are designed to pay 100% of target at the end of the three-year performance cycle if target levels of performance are achieved. Payment, if earned, is made in unrestricted shares of common stock at the end of the three-year performance period once performance results have been approved by the Committee.

Vesting for 50% of the PSUs will be based on MUSA’s TSR performance between 2014 and 2016 relative to the Company’s peer group, with payouts at the threshold level of performance equal to 50% of target and maximum payouts capped at 200% of target. The Committee considers relative TSR an appropriate metric as it aligns the pay for our officers to the appreciation (or reduction) our shareholders receive in their investment in Murphy USA. TSR achievement and corresponding payout levels are as follows:

Vesting for the remaining 50% of the PSUs will be based on MUSA’s three-year average ROACE performance between 2014 and 2016 as compared to the Company’s three-year ROACE targets set by the Committee at the beginning of the performance period, with payouts at the threshold level of performance equal to 50% of target and maximum payouts capped at 200% of target.

D.    Employee Benefits and Perquisites

Murphy USA’s executives are provided usual and customary employee benefits available to all employees (except certain hourly retail employees). These include qualified defined contribution (Savings) plan (401(k)), health insurance, life insurance, accidental death and dismemberment insurance, medical/dental insurance, vision insurance, and long-term disability insurance.

The purpose of the Savings Plan, a tax-qualified defined contribution retirement plan, for employees of Murphy USA is to provide retirement and incidental benefits for all employees who participate. All employees are allowed to contribute on a pre-tax basis up to 25 percent of their eligible pay. The Company matching contributions are limited to dollar for dollar on the first six percent. Participating employees are immediately vested in all employee and Company matching contributions.

Murphy USA provides a Supplemental Executive Retirement Plan (“Murphy USA SERP”), an unfunded, nonqualified defined contribution plan to eligible executives including the NEOs. The Murphy USA SERP is intended to restore to certain highly-compensated individuals qualified defined contribution (Savings and profit-sharing) plan benefits restricted under the Internal Revenue Code of 1986 (the “IRC”).

Murphy USA offers limited perquisites to our NEOs consistent with our peer group. The Board of Directors has authorized up to 50 hours annually of personal use of Company aircraft for our CEO as part of his total compensation package. The value of such personal use is

periodically reported to the Committee and will be reported as taxable income to the CEO with no income tax assistance or gross-ups provided by the Company.

Reportable values for these programs based on the incremental costs to the Company are included in the “All Other Compensation” column of the 2014 Summary Compensation Table included on page 25 in this Proxy Statement.

Other Policies

Severance and Change in Control Protection

The Company has not entered into any employment, CIC or termination agreements with its NEOs other than with the CEO, which was inherited by Murphy USA in connection with the Spin-Off from prior parent Murphy Oil.

Mr. Rudolfs resigned on May 21, 2014. In consideration of a release of claims against the Company and agreement to certain restrictive covenants, Mr. Rudolfs will receive a cash payment of $417,500, payable in four equal quarterly installments, a lump sum cash payment of $120,000, and a pro-rata portion of his 2014 award under the AIP calculated based on actual performance, paid at the time awards are normally paid under the Plan.

Mr. Clyde is party to a Severance Protection Agreement (the “SPA”) provided to him by Murphy Oil when he joined Murphy Oil in August 2013, which was inherited by Murphy USA in connection with the Spin-Off. The SPA provides certain severance benefits if his employment is terminated within 24 months following a CIC. If Mr. Clyde’s employment is terminated by Murphy USA “without cause” or by Mr. Clyde for “good reason” within this 24-month window, Mr. Clyde will be entitled to his earned but unpaid compensation, a lump sum severance payment equal to three times the sum of his base salary and the average of his last three annual bonuses prior to the termination date (or, if higher, prior to the CIC), accelerated vesting of his outstanding equity-based awards (provided that any performance-based awards will be paid assuming the target level of performance) and continued life, accident, and health insurance benefits for 36 months. Mr. Clyde will not be entitled to any “golden parachute” excise tax gross-up payments. The SPA provides for an excise tax cutback to reduce payments to a level such that the excise tax under Sections 280G and 4999 of the IRC will not apply (unless the executive would receive a greater amount of severance benefits on an after-tax basis without a cutback, in which case the cutback will not apply). Pursuant to the SPA, Mr. Clyde will be subject to a non-disclosure covenant and non-solicitation and non-competition restrictive covenants for 12 months following any such termination.

Under the terms of the LTIP, in the event of a CIC, all outstanding equity awards will vest, become immediately exercisable or payable, and/or have all restrictions lifted (any performance-based awards will be paid assuming the target level of performance).

Stock Ownership Guidelines

To further align the interests of our executive officers with those of our shareholders, the Board of Directors expects all executive officers to display confidence in the Company through the ownership of a significant amount of our stock. Under these guidelines as set forth in the Company’s Corporate Governance Guidelines, executive officers, including our NEOs, are expected to hold Murphy USA common stock having a value that is equivalent to a multiple of each executive officer’s annualized base salary. The targeted multiples vary among the executives depending upon their position:

Because the stock ownership guidelines are a multiple of each executive officer’s annualized salary, the value that must be maintained will increase proportionally with salary increases. Executive officers are expected to achieve targets within five years of assuming their positions. Shares owned directly by the executive, including RSUs and unrestricted stock units, those owned indirectly, assuming the executive has an economic interest in the shares, and shares held through our employee benefit plans including the qualified defined contribution (Savings) plan (401(k)) and deferred compensation plan for executives are included in calculating ownership levels. Shares underlying stock options and unearned PSUs do not count toward the ownership guidelines. At December 31, 2014, all of our NEOs had met or were on track to comply with these stock ownership guidelines within the applicable five-year period.

Likewise, the each member of our Board of Directors is expected to achieve ownership of at least three times their annual cash retainer within five years of service as discussed in the Compensation of Directors section of this Proxy Statement on page 5. At December 31, 2014, all of our directors had met or were on track to comply with these stock ownership guidelines within the applicable five-year period.

The Committee will periodically assess these guidelines, monitor the executive officers’ ownership levels relative to these guidelines, and make recommendations as appropriate.

A director or executive officer may not pledge Company securities, either by purchasing Company securities on margin or holding Company securities in a margin account, until he or she has achieved the applicable stock ownership target specified in the guidelines above.

Prohibition on Hedging

In order to ensure that Murphy USA executive officers, including our NEOs, bear the full risks of Murphy USA common stock ownership, the Company has adopted a policy that prohibits hedging transactions that are designed to hedge or speculate on any change in the market value of the Company’s securities.

Recoupment/Clawback Policy

Our executive officers are subject to recoupment provisions in both the AIP and LTIP programs in the case of certain forfeiture events. If the Company restates its financial statements as a result of negligent, intentional, or gross misconduct by the recipient, the Committee may, in its discretion, require that the recipient reimburse the Company in respect of any shares issued or payments made under the AIP and/or the LTIP in the period covered by the restated financial statements.

Tax Policy

Section 162(m) of the IRC limits the deductibility of compensation paid to certain NEOs to $1 million annually unless compensation is performance-based and the performance criteria are approved by stockholders.

The Committee considers this impact when making compensation decisions and attempts to structure all elements of executive compensation to meet this exception. However, the Committee has retained the flexibility to design and maintain the executive compensation programs in a manner that is most beneficial overall to stockholders, including the payment of compensation that is subject to the deduction limits under IRC Section 162(m).

Role of the Compensation Consultant

The Committee has retained Mercer (US) Inc. (“Mercer”) as its independent compensation consultant. Mercer provides executive and director compensation consulting services to the Committee, regularly attends Committee meetings, reports directly to the Committee on matters relating to compensation for our NEOs, and participates in executive sessions without management present. Mercer provides advice and analysis to the Committee on design and level of executive and director compensation. In connection with their services to the Committee, Mercer works with executive management and the corporate human resources team group to formalize proposals for the Committee. The Committee has assessed the independence of Mercer pursuant to SEC rules and concluded that Mercer’s work for the Committee does not raise any conflict of interest.

Compensation-based Risk Assessment

In February 2015, the Committee completed a review of the Company’s policies and practices of compensating its employees (including non-executives) as they relate to the Company’s risk management profile to determine whether such policies and practices create risks that are reasonably likely to have a material adverse effect on the Company. As a result of this review, the Committee concluded that any risks arising from the Company’s compensation policies and practices for its employees were not reasonably likely to have a material adverse effect on the Company.

Compensation Committee Report

The Executive Compensation Committee has reviewed and discussed with management the foregoing Compensation Discussion and Analysis. Based on the review and discussions, the Executive Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company’s Proxy Statement.
