INFORMATION REGARDING ADMISSION TO THE ANNUAL MEETING

Everyone attending the 2014 Annual Meeting of Stockholders will be required to present both proof of ownership of Jack in the Box Inc. Common Stock and a valid picture identification, such as a driver’s license or passport. If your shares are held in the name of a bank, broker or other financial institution, you will need a recent brokerage statement or letter from such entity reflecting your stock ownership as of the record date. If you do not have both proof of ownership of Jack in the Box Inc. stock and a valid picture identification, you may be denied admission to the Annual Meeting.

Cameras and electronic recording devices are not permitted at the Annual Meeting.

We sent you these proxy materials because the Board of Directors (sometimes referred to as the “Board”) of Jack in the Box Inc. (sometimes referred to as the “Company,” “Jack in the Box,” “we,” “us,” and “our”) is soliciting your proxy to vote at the 2014 Annual Meeting of Stockholders (the “Annual Meeting”) and at any postponements or adjournments of the Annual Meeting. The Annual Meeting will be held on February 14, 2014, at 8:30 a.m. Pacific Standard Time at our corporate headquarters located at 9330 Balboa Avenue, San Diego, CA 92123. If you held shares of our Common Stock on December 17, 2013 (the “Record Date”), you are invited to attend the Annual Meeting and vote on the proposals

described below under the heading “What am I voting on?” However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may complete, sign, date, and return the enclosed proxy card. You may also vote over the Internet or by telephone.

The Notice of Annual Meeting of Stockholders (the “Notice”), Proxy Statement, the enclosed proxy card, and our Annual Report on Form 10-K for the fiscal year ended September 29, 2013, will be mailed to stockholders on or about January 10, 2014.

If you were a holder of Jack in the Box Common Stock (the “Common Stock”) either as a stockholder of record or as the beneficial owner of shares held in street name as of the close of business on December 17, 2013, the Record Date for the Annual Meeting, you may vote your shares at the Annual Meeting. As of the Record Date, there were 42,969,464

shares of Jack in the Box Inc. Common Stock outstanding, excluding treasury shares. Company treasury shares will not be voted. Each stockholder has one vote for each share of Common Stock held as of the Record Date. As summarized below, there are some distinctions between shares held of record and those owned beneficially in street name.

If, on the Record Date, your shares were registered directly in your name with the Company’s transfer agent, Computershare, then you are a “stockholder of record.” As a stockholder of record, you may vote in person at the Annual

Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to fill out and return the enclosed proxy card, or vote by telephone or Internet, to ensure your vote is counted.

If, on the Record Date, your shares were held in an account at a broker, bank, or other financial institution (we will refer to those organizations collectively as “broker”), then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that broker. The broker holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to direct your broker on how to vote the shares in your account. As a beneficial owner, you are invited to attend the Annual Meeting. However, since you are not a stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid proxy from your broker giving you the legal

right to vote the shares at the Annual Meeting, as well as satisfy the Annual Meeting admission criteria set out in the Notice.

Under the rules that govern brokers, your broker is not permitted to vote on your behalf on any matter to be considered at the Annual Meeting (other than the ratification of the appointment of KPMG LLP as our independent registered public accountants for the 2014 fiscal year) unless you provide specific instructions to the broker as to how to vote. As a result, we encourage you to communicate your voting decisions to your broker before the date of the Annual Meeting to ensure that your vote will be counted.

The Company does not expect that any matters other than the election of directors and the other proposals described in this Proxy Statement will be brought before the Annual Meeting. The persons appointed as proxies will vote in their discretion on any other matters that may properly come before the Annual Meeting or any postponements or adjournments thereof, including any vote to postpone or adjourn the Annual Meeting.

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different

accounts. Please complete, sign and return each proxy card to ensure that all of your shares are voted.

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count “FOR,” “AGAINST,” abstentions and broker non-votes. A “broker non-vote” occurs when your broker submits a proxy card for your shares of Common Stock held in street name, but does not vote on a particular proposal because the broker has not received voting instructions from you and does not have the authority to vote on that matter without instructions. Under the rules that govern brokers who are voting shares held in street name, brokers have the discretion to vote those shares on routine matters but not on non-routine matters. For purposes of these rules, the only routine matter in this Proxy Statement

is the ratification of the appointment of our independent registered public accountants. Non-routine matters in this Proxy Statement are the election of directors and the advisory vote on the compensation of our named executive officers. Therefore, if you hold your shares in street name and do not provide voting instructions to your broker, your broker does not have discretion to vote your shares on any of the proposals at the Annual Meeting other than the ratification of the independent registered public accountants. However, your shares will be considered present at the Annual Meeting for purposes of determining the existence of a quorum, as provided below.

Proposal One — Election of Directors

In the election of directors, you may vote FOR, AGAINST or ABSTAIN. The Company’s Bylaws require that in an election such as this where the number of director nominees does not exceed the number of directors to be elected, each director will be elected by the vote of the majority of the votes cast (in person or by proxy) with respect to the director. A “majority of votes cast” means that the number of shares cast “FOR” a director’s election exceeds the number of votes cast “AGAINST” that director. For purposes of determining the votes cast, only those votes cast “FOR” or “AGAINST” are included. Neither a vote to “ABSTAIN” nor a broker non-vote will count as a vote cast “FOR” or “AGAINST” a director nominee and, as a result, will have no direct effect on the outcome of the election of directors. Abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present.

In an uncontested election, a nominee who does not receive a majority of the votes cast will not be elected. An incumbent director who is not elected because he or she does not receive a majority of the votes cast will continue to serve, but will tender his or her resignation to the Board. The Nominating and Governance Committee will take action to determine whether to accept or reject the director’s resignation, or whether other action is appropriate, and will make a recommendation to the Board. Within ninety (90) days following the date of the certification of the election results, the Board will act on the Committee’s recommendation and publicly disclose its decision and the rationale for such decision.

Proposal Two — Ratification of the Appointment of Independent Registered Public Accountants

The proposal to ratify the appointment of KPMG LLP requires the affirmative vote of a majority of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote on such proposal. Abstentions will be included in the number of shares present and entitled to vote, and will have the same effect as a vote “AGAINST” this proposal. Brokers have discretionary authority to vote uninstructed shares on this proposal. Abstentions will be counted for the purpose of determining whether a quorum is present.

Proposal Three — Advisory Vote on Executive Compensation

The proposal to approve, on an advisory basis, the compensation awarded to the named executive officers for the fiscal year ended September 29, 2013, requires the affirmative vote of a majority of the shares present in person or represented by proxy at the Annual Meeting and entitled to vote on such proposal. Abstentions will be included in the number of shares present and entitled to vote, and will have the same effect as a vote “AGAINST” the proposal. Broker non-votes will not count as a vote cast “FOR” or “AGAINST” the proposal, and will not be included in calculating the number of votes necessary for approval of this proposal. Abstentions and broker non-votes will be counted for the purpose of determining whether a quorum is present.

A quorum of stockholders is necessary to hold a valid annual meeting. A quorum will be present if the holders of at least a majority of the total number of shares of Common Stock entitled to vote are present, in person or by proxy, at the Annual Meeting. Abstentions and shares represented by

broker non-votes are counted for the purpose of determining whether a quorum is present. If there are insufficient votes to constitute a quorum at the time of the Annual Meeting, we may adjourn the Annual Meeting to solicit additional proxies.

If you are a stockholder of record, you can vote in the following ways:

If you are a beneficial owner, you can vote in the following way:

If your shares are held in street name or through a benefit or compensation plan, your broker or your plan trustee should give you instructions for voting your shares. In these cases, you may vote by Internet, telephone or mail, as instructed by your broker, trustee, or other agent. Shares beneficially held through a benefit or compensation plan cannot be voted in person at the Annual Meeting. You may vote your shares beneficially held through your broker in person if you satisfy the admission requirements to the Annual Meeting as described in the Notice and you obtain a valid proxy from your broker giving you the legal right to vote the shares at the Annual Meeting.

The written statement or subsequent proxy should be delivered to Jack in the Box Inc., 9330 Balboa Avenue, San Diego, CA 92123, Attention: Corporate Secretary, or hand delivered to the Corporate Secretary before the taking of the vote at the Annual Meeting.

If you are a beneficial owner and hold shares through a broker, bank, or other financial institution, you may submit new voting instructions by contacting your broker, bank, or other nominee. You may also change your vote or revoke your voting instructions in person at the Annual Meeting if you obtain a signed proxy from the broker, bank, or other nominee giving you the right to vote the shares.

The Company will pay the cost of preparing, printing, and mailing the Notice and the proxy materials. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries, and custodians holding shares of Common Stock beneficially owned by others, to forward to such beneficial owners. The Company may reimburse persons representing beneficial owners of Common Stock for their costs of forwarding solicitation materials to the beneficial owners. If you choose to access proxy materials or vote over the Internet or by telephone, you are responsible for Internet or

telephone charges. We have engaged Innisfree M&A Incorporated (“Innisfree”), a proxy-solicitation firm, to provide advice to the Company with respect to the 2014 Annual Meeting of Stockholders and to assist us in the solicitation of proxies, for which the Company will pay a fee of $15,000 plus reimbursement of certain out-of-pocket expenses. In addition to solicitation by mail, proxies may be solicited personally, by telephone, or by Innisfree. They may also be solicited by directors, officers, or employees of the Company, who will receive no additional compensation for such activities.

Preliminary voting results will be announced at the Annual Meeting. We will publish final results in a Current Report on Form 8-K that we expect to file with the Securities and Exchange Commission within four business days of the Annual Meeting. After the Form 8-K is filed, you may obtain a

copy by visiting the SEC’s website at www.sec.gov, visiting our website or contacting our Investor Relations Department by writing to Investor Relations Department, Jack in the Box Inc., 9330 Balboa Avenue, San Diego, CA 92123 or by sending an email to Investor.relations@jackinthebox.com.

All of the directors of the Company are elected annually and serve until the next Annual Meeting and until their respective successors are elected and qualified. The current nominees (each of whom are currently serving as directors of the Company) for election as directors are set forth below. All of the nominees have indicated their willingness to serve, and

have consented to be named in the Proxy Statement. If any should be unable or unwilling to stand for election, the shares represented by proxies may be voted for a substitute designated by the Board, unless a contrary instruction is indicated in the proxy.

We operate within a comprehensive corporate governance structure that includes the highest standards of professional and personal conduct. Our Corporate Governance Principles and Practices, our ethics Code of Conduct, the charters for our Audit Committee, Compensation Committee, Finance Committee and Nominating and Governance Committee and other corporate governance information are available at

www.jackinthebox.com/investors/corporategovernance. These materials are also available in print to any stockholder upon written request to the Company’s Corporate Secretary, Jack in the Box Inc., 9330 Balboa Avenue, San Diego, CA 92123. The information on our website is not a part of this Proxy Statement and is not incorporated into any of our filings made with the Securities and Exchange Commission.

The Board has analyzed the independence of each director. It has determined that Messrs. Goebel, Murphy, Myers, Tehle and Wyatt and Ms. Kleiner and Ms. Webb (consisting of all of our non-employee directors) are independent directors under the NASDAQ Listing Rules, as well as the additional Director Independence Guidelines adopted by the Board. As part of its analysis, the Board determined that none of these directors have a material relationship with the Company. Mr. Comma, our current Chief Executive Officer, and Ms. Lang, who held that role until her retirement on January 1, 2014, were determined not to be independent due to serving as our Chief Executive Officer, and as an employee of Jack in the Box Inc.

The Jack in the Box Inc. Director Independence Guidelines provide that a director shall not be independent if he or she is: (a) a director, executive officer, partner or owner of 5% or greater interest in a company that either purchases from or makes sales to our Company that total more than one percent of the consolidated gross revenues of such company for that fiscal year; (b) a director, executive officer, partner or owner of 5% or greater interest in a company from which our Company borrows an amount equal to or greater than one percent of the consolidated assets of either our Company or such other company; or (c) a trustee, director or executive officer of a charitable organization that has received in that fiscal year discretionary donations from our Company that total more than one percent of the organization’s latest publicly available national annual charitable receipts.

The Board held seven meetings in fiscal 2013. We expect each director to attend each meeting of the Board and of the committees on which he or she serves. We also expect them to attend the Annual Meeting of Stockholders. During the time each director served on the Board in fiscal 2013, each

director attended more than 75% of the meetings of the Board and of the committees on which he or she served. All of the then-sitting directors attended the 2013 Annual Meeting. We currently expect all of our directors standing for election to be present at the 2014 Annual Meeting.

The Nominating and Governance Committee’s Charter provides that the Committee will annually assess the leadership structure of the Board and recommend a structure to the Board for approval. In August 2013, the Board of Directors, with the counsel of the Nominating and Governance Committee, conducted that assessment, including assessing whether (i) the roles of Chief Executive Officer (“CEO”) and Chairman of the Board should continue to be combined through and upon the succession of Mr. Comma to CEO, effective January 1, 2014 and (ii) the Board should continue to have an independent Lead Director. The Committee recommended to the Board, and the Board approved, that the current structure of combining the positions of Chairman and CEO and appointing a Lead Director is effective and appropriate for the Company at this time.

The Board determined that combining the positions of Chairman and CEO continues to be in the best interests of the Company. The Board determined that having one individual serve in both roles provides for clear leadership, accountability, and alignment on corporate strategy. The Board believes that combining the roles of Chairman and CEO puts Mr. Comma in the best position to use his in-depth knowledge of our industry, our business and its challenges, and our stakeholders, including our stockholders, employees, and franchisees, to provide the Board with the information and leadership needed to set agendas and direction for the Company. The Board does not believe that having an independent Chairman would make the Board’s risk oversight processes more effective. The Board noted that, under Ms. Lang’s tenure as Chairman and CEO, and Mr. Goebel’s

service as Lead Director, which is continuing, the Board has received timely and relevant information regarding the Company’s business. Mr. Comma has long been a key member of the management team, and attended all non-executive sessions of the Board meetings during fiscal 2013, as well as Board committee meetings, as needed, in recent years.

In reaching its recommendation, the Board also considered the long standing policies and practices at Jack in the Box for strong, independent oversight, including:

Based on these factors, the Board concluded that retaining the current Board leadership structure provides valuable stability and effective leadership.

The independent directors have appointed a Lead Director from among the independent directors serving on the Board. Our Corporate Governance Principles and Practices provide for the Lead Director to fulfill the following functions:

The Lead Director may perform other functions as the Board may direct, including advising management on the agenda for Board meetings. Mr. Goebel currently serves as Lead Director.

The Board’s goal is to have an ongoing program for effective senior leadership development and succession. As reflected in our Corporate Governance Principles and Practices, the Board’s practice is to have the CEO review annually with the full Board the abilities of the key senior managers and their likely successors. The Board also considers management succession issues when meeting in executive session. Additionally, the Board oversees long range plans for management development and retention, and executive succession, including CEO succession. During 2013, CEO

and Chairman Lang announced her retirement from both positions, effective January 1, 2014. The Board’s executive succession process led to the selection of Mr. Comma, then President and COO and longtime key member of management, to succeed her as CEO and Chairman. At times, the Board will delegate to the Compensation Committee responsibility to review and advise on succession planning, in which case the Board expects the Committee to review such plans with management and the Board and to make recommendations to the Board with respect thereto.

Management is responsible for the Company’s day-to-day risk management. The Board’s role is to provide oversight of the processes designed to identify, assess and monitor key risks and risk mitigation activities. The Board fulfills its risk oversight responsibilities through (i) reports directly from managers responsible for the management of particular business risks,

and (ii) reports by each Committee Chair regarding the Committee’s oversight of specific risk topics.

The Board has delegated oversight of specific risk areas to Committees of the Board. For example, the Audit Committee discusses with management the Company’s major risk exposures and the steps management has taken to monitor

and mitigate those exposures, including the processes for enterprise risk assessment and risk management. As another example, the Compensation Committee discusses with management and its independent consultant the risks arising in connection with the design of the Company’s compensation programs and succession planning. The risk

oversight responsibility of each Board Committee is described in its committee charter available at www.jackinthebox.com/investors/corporategovernance. A more detailed discussion of the Compensation Committee’s oversight of compensation risk is found in the section “Risk Analysis of Compensation Programs” contained in this proxy.

Our independent, non-employee directors meet in executive session without management present at each regularly scheduled meeting of the Board. Mr. Goebel is currently designated by the Board to act as the Lead Director for such

executive sessions. The Audit Committee also holds executive sessions at each regularly scheduled meeting, and the other committees of the Board meet in executive session as they deem appropriate.

The Board of Directors has five standing committees: Audit, Compensation, Nominating and Governance, Finance, and Executive. The authority and responsibility of each committee is summarized below. A more detailed description of the functions of the Audit, Compensation, Nominating and Governance, and Finance Committees is included in each committee charter available at www.jackinthebox.com/investors/corporategovernance.

Committee Member Independence. The Board has determined that each member of the Audit, Compensation, Nominating and Governance, and Finance Committees is an independent director for purposes of the NASDAQ Listing Rules as well as under the additional Director Independence Guidelines adopted by the Board. In addition, the members of the Audit Committee are all independent as required under Rule 10A-3(b)(1)(ii) under the Securities Exchange Act of 1934, and the members of the Compensation Committee meet the definitions of (i) a “non-employee director” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended, (ii) an “outside director” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (“IRC”) and (iii) the recently added requirements of Rule 10C-1 under the Securities Exchange Act of 1934.

Audit Committee. As more fully described in its charter, the Audit Committee assists the Board of Directors with overseeing:

The Audit Committee has sole authority to select, evaluate, and when appropriate, replace the Company’s independent registered public accountants. The Audit Committee has appointed KPMG LLP (“KPMG”) as its independent registered public accountants for fiscal 2014 and is asking the stockholders to ratify this appointment in Proposal 2. In the event the stockholders fail to ratify the appointment, the Audit Committee will reconsider the selection. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent auditing firm at any time during the year.

The Audit Committee meets at least each quarter with KPMG, the Company’s Vice President of Internal Audit, and management to review the Company’s annual and interim consolidated financial results before the publication of quarterly earnings press releases and the filing of quarterly and annual reports with the Securities and Exchange Commission (“SEC”). The Audit Committee also meets at least each quarter in private sessions with KPMG, management and the Vice President of Internal Audit. The Audit Committee also oversees the Company’s Business Ethics Program, which includes receiving a quarterly report from the Ethics Officer. The Board of Directors has determined that each member of the Audit Committee qualifies as an “audit committee financial expert” as defined by SEC rules. Additional information regarding the Audit Committee is set forth in the Report of the Audit Committee on page 21. The Audit Committee held five meetings in fiscal 2013.

Compensation Committee. As more fully described in its charter, the Compensation Committee assists the Board in discharging the Board’s responsibilities relating to director and executive officer compensation, and it oversees the performance evaluation of management. The Compensation Committee reviews and approves the Company’s compensation philosophy, each of the compensation components, equity and benefit plans, and the compensation of executive officers, including performance goals and objectives for performance-based executive compensation. The Compensation Committee discusses with management

and reports to the Board major risk exposures and the monitoring and mitigation activities undertaken by management in connection with the design and administration of the Company’s compensation programs and succession planning. The Committee has approved the disclosures in the Company’s Compensation Discussion and Analysis that begins on page 26 of this Proxy Statement. The Compensation Committee held seven meetings in fiscal 2013.

Executive Committee. The Executive Committee is authorized to exercise all powers of the Board in the management of the business and affairs of the Company while the Board is not in session. The Executive Committee did not meet in fiscal 2013.

Finance Committee. As more fully described in its charter, the Finance Committee assists the Board in advising and consulting with management concerning financial matters of importance to the Company. Topics considered by the Committee include the Company’s capital structure, financing arrangements, stock repurchase programs, capital investment policies, investment performance oversight for the Company’s retirement plans, the budget process, and the financial implications of major acquisitions and divestitures. The Finance Committee discusses with management and reports to the Board major risk exposures and the monitoring and mitigation activities undertaken by management in connection with the matters overseen by the Committee, including proposed major transactions, capital structure, investment portfolio including employee benefit plan investments, financing arrangements, and share repurchase programs. The Finance Committee held four meetings in fiscal 2013.

Nominating and Governance Committee. As more fully described in its charter, the Nominating and Governance Committee duties include identifying and recommending qualified candidates to be nominated for election as directors at the annual meeting or to be appointed by the Board to fill an existing or newly created vacancy on the Board; recommending members of the Board to serve on each Board committee; and annually reviewing and recommending the leadership structure of the Board. The Nominating and Governance Committee discusses with management and reports to the Board major risk exposures in connection with matters overseen by the Committee. Its activities include:

All nominees for election as Directors currently serve on the Board of Directors and are known to the Nominating and Governance Committee in that capacity. The Nominating and Governance Committee held five meetings in fiscal 2013.

Policy Regarding Consideration of Candidates for Director. The Nominating and Governance Committee has the responsibility to identify, screen, and recommend qualified candidates to the Board for nomination as directors. In order to be evaluated pursuant to the Nominating and Governance Committee’s established procedures, stockholder recommendations for candidates for the Board must be sent in writing to the following address at least 120 days prior to the first anniversary of the date of the previous year’s Annual Meeting of Stockholders:

Nominating and Governance Committee of the Board of Directors

c/o Office of the Corporate Secretary

Jack in the Box Inc.

9330 Balboa Avenue

San Diego, CA 92123

Any recommendation submitted by a stockholder to the Nominating and Governance Committee must include the same information concerning the potential candidate and the recommending stockholder as would be required under Article III, Section 3.16 of the Jack in the Box Inc. Bylaws if the stockholder wished to nominate the candidate directly. In evaluating director candidates, the Nominating and Governance Committee considers the qualifications listed in the Jack in the Box Inc. Corporate Governance Principles and Practices, which are available at www.jackinthebox.com in the “Investors” section under the link for “Corporate Governance.” The following are some of the factors considered by the Nominating and Governance Committee in evaluating director candidates:

The Nominating and Governance Committee may also consider such other factors as it may deem are in the best interests of the Company and its stockholders. The Committee considers all candidates regardless of the source of the recommendation. In addition to stockholder recommendations, the Committee considers recommendations from current directors, Company personnel and others. From time to time, the Nominating and Governance Committee retains a search firm to assist it in identifying and screening candidates, and conducting reference checks. The Committee applies the same standards in evaluating candidates submitted by stockholders as it does in evaluating candidates submitted by other sources.

A candidate nominated by a stockholder for election at an Annual Meeting of Stockholders will not be eligible for election unless the stockholder proposing the nominee has provided timely notice of the nomination in accordance with the

deadlines (at least 120 days and no more than 150 days prior to the first anniversary of the date of the previous year’s Annual Meeting of Stockholders) and other requirements set forth in the Company’s Bylaws.

Article III, Section 3.16 of the Company’s Bylaws provides that, in order to be eligible for election as a Director, a candidate must deliver to the Corporate Secretary statements indicating whether the candidate:

The foregoing is a summary of provisions of the Company’s Bylaws, and is qualified by reference to the actual provisions of Article III, Section 3.16.

Jack in the Box is committed to establishing and maintaining an effective compliance program that is intended to increase the likelihood of preventing, detecting, and correcting violations of law or Company policy. In 1998, the Company adopted a Code of Conduct (the “Code”) which is applicable to all officers, and employees, as well as to our Board of Directors. The Company also provides our franchisees and significant vendors with our Code and procedures for

communicating any ethics or compliance concerns to the Company. This Code is revised from time to time, most recently with minor updates in 2013.

The Code is available on the Company’s website www.jackinthebox.com, in the “Investors” section, under “Corporate Governance.” We will disclose amendments to, or waivers of our Code that are required to be disclosed under

the securities rules, by posting such information on the Company’s website, www.jackinthebox.com. Any waiver of our Code for directors or executive officers must be approved

by the Board of Directors. The Company has not made any such waivers and does not anticipate making any such waiver.

No member of our Compensation Committee is an officer, former officer, or employee of the Company. During fiscal 2013, no member of the Compensation Committee had any relationship with the Company requiring disclosure under Item 404 of Regulation S-K. During fiscal 2013, no

interlocking relationship existed between any of our executive officers or Compensation Committee members, on the one hand, and the executive officers or Compensation Committee members of any other entity, on the other hand.

Stockholders or others who wish to communicate any concern of any nature to the Board of Directors, any Committee of the Board, or any individual director or group of directors, may write to a director or directors in care of the Office of the Corporate Secretary, Jack in the Box Inc. 9330 Balboa Avenue, San Diego, CA 92123, or telephone 1-888-613-5225. Your letter should indicate that you are a stockholder of the Company.

Comments or questions regarding our accounting, internal controls or auditing matters will be referred to members of our Audit Committee. Comments or questions regarding the nomination of directors and other corporate governance matters will be referred to members of the Nominating and

Governance Committee. For all other matters, our Corporate Secretary will, depending on the subject matter:

Each director receives an annual cash retainer for his or her service on the Board, service on Board committees, and service as Lead Director, as applicable. There are no meeting fees. Retainers are paid in a single installment on the first business day of the month following the annual stockholder meeting each year. Directors with less than one full year of service receive a prorated retainer that is paid on the first business day of the month following his or her appointment to the Board.

2013 RETAINERS

Deferred Compensation Plan — Directors may elect to defer receipt of some or all of their cash retainers in the form of Common Stock equivalents under the Jack in the Box Inc. Deferred Compensation Plan for Non-Management Directors (the “Director Deferred Compensation Plan”). The number of Common Stock equivalents credited to a director’s account is based on a per share price equal to the average of the closing price of Jack in the Box Inc. Common Stock on the NASDAQ Stock Market for the ten (10) trading days immediately preceding the date the deferred compensation is credited to the director’s account. The director’s account is settled in an equal number of shares of Common Stock upon a pre-specified distribution date or the director’s termination of service from the Board. The Director Deferred Compensation Plan is a non-qualified plan under the IRC.

Each director receives an annual grant of RSUs under the 2004 Stock Incentive Plan. The Company grants RSUs for the following reasons:

To determine the number of RSUs granted, the annual equity award value of $90,000 is divided by the closing price of Common Stock on the date of the annual grant. The RSUs vest on the first business day 12 months from the date of grant or upon the director’s termination of service with the Board. Directors may elect to defer receipt of their RSUs until a later date in compliance with IRC 409A.

The following is the report of the Audit Committee with respect to Jack in the Box Inc.’s audited consolidated financial statements for the fiscal year ended September 29, 2013.

The Audit Committee has reviewed and discussed the annual consolidated financial statements with management and KPMG LLP, the Company’s independent registered public accounting firm (the “independent auditor”). Management is responsible for the financial reporting process, the system of internal controls, including internal control over financial reporting, risk management and procedures designed to ensure compliance with accounting standards and applicable laws and regulations. The independent auditor is responsible for performing an independent audit of the consolidated financial statements and expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States of America, as well as expressing an opinion on the effectiveness of internal control over financial reporting.

The Audit Committee met on five occasions in the fiscal year ended September 29, 2013. The Audit Committee met with the independent auditor, with and without management present, to discuss the results of its audits and quarterly reviews of the Company’s financial statements. The Audit Committee also discussed with the independent auditor the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1, AU Section 380), as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T. The Audit Committee also received from the Company’s independent auditor the written disclosures and the letter required by applicable requirements of PCAOB

regarding their communications with the Audit Committee concerning independence and has discussed with the independent auditor its independence from the Company. The Audit Committee also has considered whether the provision of non-audit services to the Company is compatible with the independence of the independent auditor.

In performing its functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the work and assurances of the Company’s management, internal audit group and independent auditor, which, in their reports, express opinions on the conformity of the Company’s annual financial statements with U.S. generally accepted accounting principles.

Based on the reviews and discussions referred to above, and the reports of KPMG, the Audit Committee recommended to the Board of Directors, and the Board of Directors approved, the inclusion of the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended September 29, 2013, for filing with the SEC.

THE AUDIT COMMITTEE

This report is not deemed to be incorporated by reference in any filing by the Company under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent that the Company specifically incorporates this report by reference.

The following table presents fees billed for professional services rendered by KPMG, the Company’s independent registered public accountants, for the fiscal years ended September 29, 2013 and September 30, 3012.

Registered Public Accountants’ Independence. The Audit Committee has considered whether the provision of the above-noted services is compatible with maintaining KPMG’s independence, and has determined that the provision of such services has not adversely affected KPMG’s independence.

Policy on Audit Committee Pre-Approval of Services. The Company and its Audit Committee are committed to ensuring the independence of the independent registered public accountants, both in fact and in appearance. In this regard, the Audit Committee has established a pre-approval policy in accordance with applicable securities rules. The Audit Committee’s pre-approval policy is set forth in the Audit Committee Pre-Approval Policy, included as Exhibit A to this Proxy Statement.

Executives of our Qdoba brand (not among our NEOs in fiscal 2013) did not earn an annual incentive payout for fiscal 2013 due to the brand not achieving its threshold financial targets.

The November 2010 PSU award for our NEOs, which was based on performance targets for the three fiscal year period 2011-2013, vested in November 2013. The PSU targets were: (a) specified guest satisfaction goals (weighted one-third) and (b) Return on Invested Capital (“ROIC”) goals (weighted two-thirds). During that three-year period, the Company achieved the guest satisfaction goals at a level above the threshold, but slightly below target, and failed to achieve the threshold ROIC goals. Accordingly, in November 2013, our NEOs received a weighted payout of 29% of the target number of units granted for this PSU award.

The Company delivered another year of strong financial and operational performance in fiscal 2013, and we believe that the pay-for-performance philosophy of our executive compensation program was an important driver of our success. Our performance reflects the strength of our leadership team and employees, the success of our franchise business model, the restructuring activities we have undertaken to drive organizational efficiencies, and our focus on enhancing the entire guest experience in our restaurants. Fiscal 2013 highlights include:

These accomplishments helped us substantially exceed our annual incentive plan performance target for Operating EPS; achieve our Restaurant Operating Margin target; and achieve our fiscal 2013 strategic goals at an overall level above target, as described in Fiscal 2013 Compensation Section VI below. Accordingly, our NEOs received annual incentive payouts for fiscal 2013 of 176% of target payout, ranging from 97% to 176% of NEOs’ base salary. No Qdoba annual incentive was paid out for the fiscal year.

The Committee determined, based on market data and advice provided by its independent consultant that the target TDC for our CEO in fiscal 2013 was $4.8 million (consisting of base salary of $995,000, target annual incentive of $995,000, and target long-term incentive (LTI) guideline of $2.8 million). Consistent with our compensation philosophy, TDC is generally +/-15% of the market median (including +/-30% of LTI guideline), based on the Committee’s discretion and consideration of performance, retention, and other factors. Ms. Lang’s actual TDC in fiscal 2013 was $6.2 million.

The increase in actual TDC over target TDC was primarily reflective of: (a) an additional $753,000 due to an annual incentive payout at 176% of target based on the Company’s above target performance on the annual goals; (b) an additional $400,000 in LTI value due to the Committee setting her actual grant above the guideline to recognize her strong past performance and provide her greater potential value in long-term incentive than in base pay; and (c) an additional $218,000 in the “fair value” calculation used for valuing stock options and full value shares under accounting principles, and due to the appreciation of our stock price between (i) when the Committee determines the number of shares awarded utilizing the 60 day average closing price approximately two weeks prior to Committee approval date ($26.91) and (ii) the increased price on the grant date ($27.49), which, in accordance with our standard practice, is the second business day of the open “window” (under the Company’s Employee/Insider Trading Policy) following the release of the prior fiscal year-end earnings. The LTI component values for each NEO are provided in Section VI.c. — Fiscal 2013 Compensation — Long-Term Incentive Compensation.

In 2013, we sought an advisory vote from our stockholders regarding our executive compensation program and received an 87% favorable vote supporting the program. The Committee considers the results of the advisory vote as it completes its annual review of each pay element and the compensation packages provided to our NEOs and other executives. Given the significant level of stockholder support and our stockholder outreach throughout the year, the Committee concluded that our compensation program

continues to provide a competitive pay for performance package that effectively incentivizes our NEOs and other executives to maximize stockholder value. The program also encourages retention of talented NEOs and executives. Accordingly, the Committee determined not to make any significant changes as a result of the vote. The Committee will continue to consider the outcome of our say-on-pay votes and our stockholder views when making future compensation decisions for the NEOs and executives.

Competitive Pay for Expected Performance

Exemplary Pay for Exemplary Performance

Our compensation programs are designed so that potential compensation opportunities are appropriate relative to each executive’s level of responsibility and impact. While program design is similar for executives at the same level, actual pay

may vary based on an executive’s base pay and individual performance over time. In fiscal 2013, our CEO’s targeted TDC was approximately 2.3 times higher than the next highest paid executive.

Each year the Committee relies on a variety of data points to assess the competitiveness of our executive compensation program and the individual compensation of our executives. Information the Committee uses to perform this analysis includes:

The Committee also considers the Company’s financial performance relative to our Peer Group. Although we target compensation to approximate a reasonable range of the Market median, as described in our compensation philosophy, the Committee has discretion to determine if it is in the Company’s best interest to provide any executives with compensation that varies from this general approach.

We use a Peer Group to assess the competitive pay levels of our NEOs and other executives, and to evaluate program design elements. The Committee believes the Peer Group should consist of a combination of restaurant and retail companies because these are the primary companies with which we compete for executive talent.

Our practice in selecting Peer Group companies is to look for companies that are comparable in size (GAAP revenue and market capitalization, generally between 0.5x and 2.0x Jack in the Box). The Committee also reviews systemwide sales, number of locations, business models and consumer focus. In reviewing systemwide sales comparisons, the Committee focuses on the eleven restaurant companies in the Peer Group (for which comparative data is applicable).

For 2013, the Committee’s compensation consultant recommended and the Committee approved the following changes to the Peer Group:

The Committee approved the revised fiscal 2013 Peer Group in August 2012, based on the parameters described above, and the peer group trailing four-quarter revenue and market cap data at the time. At such time, the Peer Group members’ revenue and market cap medians were $2.2 billion and $1.8 billion, respectively, compared with Jack in the Box revenue and market cap of $1.6 billion and $1.2 billion. The Committee believes that the fiscal 2013 Peer Group provided sound representation of competitive pay levels and practices.

Role of the Compensation Committee

The Committee works closely with its independent consultant and meets regularly, including in executive session without management present, to make decisions on our executive compensation program and on the compensation of our CEO and other executives. The Committee reviews a variety of market data and information, including Company, Peer Group, restaurant/retail industry, and general industry compensation information, and considers the recommendations of its independent consultant when making compensation decisions. The Committee Chair reports the actions of the Committee to the Board at each regular meeting.

The Committee’s responsibilities include reviewing and approving:

Role of the Independent Compensation Consultant

The Committee has retained Semler Brossy Consulting Group, LLC (“Semler Brossy” or “Consultant”) as its independent compensation consultant since January 2010. The Consultant reports directly to the Committee and performs no other work for the Company. The Committee has analyzed whether the work of Semler Brossy as a compensation consultant has raised any conflict of interest, taking into consideration the following factors: (i) the provision of other services to the Company by Semler Brossy; (ii) the amount of fees from the Company paid to Semler Brossy as a percentage of Semler Brossy’s total revenue; (iii) Semler Brossy’s policies and procedures that are designed to prevent conflicts of interest; (iv) any business or personal relationship of Semler Brossy or the individual compensation advisors employed by the firm with an executive officer of the Company; (v) any business or personal relationship of the individual compensation advisors with any member of the Committee; and (vi) any stock of the Company owned by Semler Brossy or the individual compensation advisors whom it employs. The Committee has determined, based on its analysis of the above factors, that the work of Semler Brossy and the individual compensation advisors employed by

Semler Brossy as compensation consultants to the Company has not created any conflict of interest.
