ABOUT STADIUM CAPITAL

Founded in 1997, Stadium Capital is an investment advisory firm that manages approximately $650 million in assets. The firm focuses exclusively on investing in small and micro-cap public companies. As a result of its private equity approach to investing in the public markets, Stadium Capital maintains a concentrated portfolio and it applies a highly disciplined, research driven, and patient approach to investing. Stadium Capital’s main office is located in New Canaan, CT and it has nine investment professionals.

Stadium Capital is the Company’s largest stockholder and the beneficial owner of an aggregate of 2,513,220 shares of Common Stock, representing over 11% of the outstanding Common Stock. Stadium Capital has been a large, continuous stockholder of the Company since 2006.

REASONS FOR THIS PROXY SOLICITATION

Stadium Capital believes that the Company’s poor governance and history of underperformance call for directors with the fresh perspectives and sense of urgency necessary to unlock the Company’s full potential. To that end, Stadium Capital has nominated three highly experienced and respected individuals who it believes would, consistent with the best interests of the Company, help improve stockholder value and the Company’s operations and corporate governance. Stadium Capital believes that the Nominees have exceptional qualifications and will bring insightful and experienced voices to the Company’s Board of Directors (the “Board”). As the Company’s largest stockholder, Stadium Capital believes in the Company and its potential — and has invested over $25 million in acquiring shares of Common Stock in support of that belief.

The Board Has a Multi-Year Record of Underperformance

Stadium Capital believes that the Board, as currently constructed, has failed to effectively oversee management effectively and has not created a governance structure to foster accountability — for either management or the Board itself. Stadium Capital believes that these failings have helped lead directly to the Company’s sustained operational underperformance, which has led to poor stockholder returns, on both an absolute and relative basis, over a long period of time.

For example, over the past one, five and 10 years, the Company has underperformed its peer group, the S&P 600 Retailing Index and the Russell 2000 by a significant amount.

1

The Company’s Poor Governance Prevents Directors From Being Held Accountable

Stadium Capital believes that some of the Company’s underperformance can be traced to the Company’s poor governance practices, which reduce management and Board accountability and therefore help enable sustained underperformance. For example:

•

The Board is classified, meaning that only a few directors stand for election each year.

​

•

The Company uses a plurality voting standard in uncontested director elections, resulting in “rubber stamp” director elections.

​

•

The Charter and Bylaws contain numerous unusually high supermajority vote requirements, each of which appears specifically intended to frustrate the will of a majority of the Company’s stockholders. Specifically, the Charter and Bylaws require a vote of at least 80% of the outstanding shares (1) to remove directors for cause; (2) for stockholders to amend the Bylaws; (3) to amend the Charter to permit stockholders to act by written consent; and (4) to amend the Charter to permit stockholders to call special meetings.

​

Stadium Capital believes that the Board should take immediate action to replace each of these archaic governance practices with ones that provide stockholders with a meaningful opportunity to hold directors accountable for poor performance. Stadium Capital also believes that directors who are truly accountable to stockholders will act with urgency to improve the Company’s performance. If the Nominees are elected, Stadium Capital intends to work constructively with the Board and the Company’s management to see that these matters receive appropriate attention.

Stadium Capital’s Experienced Nominees Bring a Fresh Perspective and a Sense of Urgency

Stadium Capital believes that the experience of the Nominees would prove invaluable in addressing the issues facing the Company.

For example:

•

Mr. DeMarco has served on the Board since 2011. During this time, he has been instrumental in fixing some of the Board’s problems, including (1) helping the Board obtain and analyze the necessary data to improve rigor around topics such as capital allocation and capital structure; (2) formalizing the review of underperforming stores; and (3) successfully advocating for the first multi-year strategic operating and capital plan produced by Company management in many years. As a representative of Stadium Capital, the Company’s largest stockholder, Mr. DeMarco brings an owner’s perspective to the Board and more than a decade of successful investing experience.

​

•

Mr. Donatiello runs a highly successful marketing and strategy consulting firm, and his extensive experience in the consumer, media and technology space will make him a valuable addition to the Board. In addition, Mr. Donatiello has deep experience in strategic management and as a director of numerous public and private companies and is a lecturer on board governance at Stanford University’s Graduate School of Business.

​

•

Mr. McConnell possesses unique experience as an investor, a chief executive officer of consumer-facing businesses and a restructuring expert. Specifically, he has experience investing in public companies, articulating strategies for improved performance, and implementing such strategies as a director and/or executive officer. His experience in various public company director capacities, including as board chairman and as a chair of audit, governance and compensation committees, also make him a valuable addition to the Board.

​

Each Nominee has a history of working collaboratively and constructively in the boardroom. They each bring substantial experience and a diverse set of relevant skills and independent perspectives. Stadium Capital selected the Nominees specifically for what Stadium Capital believes to be their differentiated capabilities and ability to foster the boardroom dynamics that are required to unlock value for all stockholders. Stadium Capital expects the Nominees, if elected, to work to ensure management accountability, enhanced engagement and a robust dialogue in the boardroom.

Q:

Who are the Nominees?

​

A:

The Nominees, Dominic P. DeMarco, Nicholas Donatiello, Jr. and Michael J. McConnell, are each highly qualified individuals with a diversity of experience relevant to the Company. All of the nominees have experience serving on the boards of directors of public companies. The principal occupation and business experience of each Nominee is set forth under the caption “Proposal 1 —  Election of Directors.”

​

Q:

Who can vote at the Annual Meeting?

​

A:

If you are a record or beneficial owner of shares of Common Stock as of the close of business on the Record Date, then you have the right to vote at the Annual Meeting.

​

Q:

How many shares of Common Stock must be voted in favor of the Nominees to elect them?

​

A:

Directors of the Company are elected by a plurality of all of the votes cast at the Annual Meeting, assuming a quorum is present. For this purpose, “plurality” means that the individuals receiving the greatest number of votes are elected as directors, up to the maximum number of directors to be elected.

​

The Company has disclosed that three directors are standing for election at the Annual Meeting. Accordingly, at the Annual Meeting, the three nominees who receive the greatest number of  “FOR” votes (among votes properly cast in person or by proxy) will be elected as Class A directors for terms expiring at the 2018 Annual Meeting and until their respective successors have been duly elected and qualified. A signed proxy that withholds authority with respect to the election of any or all nominees will be counted for purposes of determining whether there is a quorum, but, with respect to any specific nominee, will not be considered to have been voted for such nominee. Broker non-votes, if any, are not considered votes cast and will result in the applicable nominee receiving fewer “FOR” votes for purposes of determining the three nominees receiving the most votes.

Q:

How many shares of Common Stock must be voted in favor of any proposal other than the election of directors that properly comes before the Annual Meeting?

​

A:

With respect to any proposal other than the election of directors that properly comes before the Annual Meeting, assuming a quorum is present, the approval of such proposal requires a “FOR” vote from the majority of the votes cast, affirmatively or negatively, on such proposal. Abstentions and broker non-votes, if any, will be disregarded and have no effect on the outcome of the vote.

​

Q:

What should I do in order to vote for the Nominees and any other proposals?

​

A:

If you hold your shares of Common Stock of record in your own name, please authorize a proxy to vote by signing, dating and returning the enclosed WHITE proxy card in the postage-paid envelope provided.

​

5

If your shares of Common Stock are held in “street name” in the name of a bank, brokerage firm, dealer, trust company or other nominee, only it can exercise your right to vote your shares of Common Stock and only upon receipt of your specific instructions. Accordingly, it is critical that you promptly give instructions to your bank, brokerage firm, dealer, trust company or other nominee to ensure that a WHITE proxy card is submitted on your behalf. Please follow the instructions on the enclosed WHITE voting instruction form to provide voting instructions to your bank, brokerage firm, dealer, trust company or other nominee. If your bank, brokerage firm, dealer, trust company or other nominee provides for voting instructions to be delivered by telephone or over the Internet, instructions will be included on the enclosed WHITE voting instruction form.

YOUR VOTE IS VERY IMPORTANT. If you do not plan to attend the Annual Meeting, Stadium Capital encourages you to vote the enclosed WHITE proxy card TODAY so that your shares of Common Stock will be represented and voted in accordance with your instructions. Even if you plan to attend the Annual Meeting in person, Stadium Capital recommends that you sign, date and return a WHITE proxy card so that your vote will be counted if you later decide not to attend the Annual Meeting.

Q:

Can I use the WHITE proxy card to vote for any of the Company’s nominees?

​

A:

No. Under the proxy rules, Stadium Capital may only solicit proxies in support of the Nominees. If you wish to vote for other nominees, you will need to return the Company’s blue proxy card or attend the Annual Meeting in person and vote by ballot.

​

Q:

How do proxies work?

​

Whether or not you are able to attend the Annual Meeting, Stadium Capital urges you to vote the enclosed WHITE proxy card TODAY. If you specify a choice with respect to any item by marking the appropriate box on the WHITE proxy card, the shares of Common Stock to which that proxy card relates will be voted in accordance with that specification. If no specification is made, the shares of Common Stock will be voted (1) “FOR” the election of the Nominees, Dominic P. DeMarco, Nicholas Donatiello, Jr. and Michael J. McConnell; (2) “FOR” the approval of the Company’s executive compensation; (3) “FOR” the ratification of the appointment of Deloitte & Touche LLP to serve as the Company’s independent auditors for fiscal 2015; (4) “FOR” the adoption of a majority voting standard in uncontested elections of directors; (5) “FOR” the elimination of certain supermajority voting requirements in the Charter and Bylaws; (6) “FOR” a declassified board structure; and (7) in the proxy holders’ discretion as to any other matters that may properly come before the Annual Meeting.

​

Q:

What is the deadline for submitting proxies?

​

A:

Proxies can be submitted until the polls are closed at the Annual Meeting. However, to be sure that Stadium Capital receives your proxy in time to utilize it, please provide your proxy as early as possible.

​

Q:

May I change my vote?

​

A:

Yes. Even after you have submitted your proxy, you may change your vote at any time by returning a later dated proxy card or voting at the Annual Meeting by ballot. Attendance at the Annual Meeting will not in and of itself constitute revocation of a proxy.

BACKGROUND OF THIS PROXY SOLICITATION

Stadium Capital has been a large stockholder in the Company for more than eight years. Stadium Capital is the Company’s largest stockholder and the beneficial owner of an aggregate of 2,513,220 shares of Common Stock, representing over 11% of the outstanding Common Stock.

In 2011, Stadium Capital began discussions with the Company regarding the composition of the Board, and specifically about having a representative of Stadium Capital join the Board. These discussions resulted in Mr. DeMarco’s appointment to the Board.

At the 2013 Annual Meeting of Stockholders, Stadium Capital withheld its votes from the Company’s director nominees due to concerns about governance practices and the composition of the Board.

In connection with a regularly-scheduled meeting of the Board in October 2014, Mr. DeMarco proposed that the Company (1) repeal the classified board; (2) adopt majority voting in director elections; and (3) eliminate the supermajority vote requirements in the Company’s charter and bylaws. In response, the Board expressed a willingness to discuss governance changes in February 2015. The Board knew that if it did not consider Mr. DeMarco’s proposals until February 2015, the Rule 14a-8 deadline, which was January 1, 2015, would have passed and stockholders would not be able to make Rule 14a-8 proposals in response to the Board’s decisions.

On December 18, 2014, Stadium Capital submitted to the Company a proposal urging the Board to take all necessary steps (other than any steps that must be taken by the stockholders) to eliminate the classification of the Board and to require that all directors elected after the Annual Meeting be elected on an annual basis. For additional information, see the section of this proxy statement captioned “Proposal 6 — Stockholder Proposal Requesting a Declassified Board.” Stadium Capital also sent a letter to the Board regarding its views on the Company’s governance practices and the reasons for the submission of the stockholder proposal.

On January 19, 2015, the Board formed a special committee (the “Special Committee”) to, among other things, consider the stockholder proposal submitted by Stadium Capital. The Special Committee has the full authority to take “all actions” and make all decisions that the “full Board would be empowered to take or make.” Mr. DeMarco was the only director that the Board chose to exclude from the Special Committee.

On January 21, 2015, Mr. DeMarco sent a letter to Steven G. Miller, the Company’s Chairman, Chief Executive Officer and President, concerning the formation of the Special Committee. In the letter, Mr. DeMarco stated that there was no conflict of interest between Stadium Capital and the other non-management stockholders of the Company. The letter further states that the Board ignored the potential conflicts of other directors and deliberately delegated sweeping power to the Special Committee in an overly broad manner, in order to potentially exclude Mr. DeMarco from all Board business.

On January 30, 2015, Mr. Miller sent Mr. DeMarco a letter providing the Special Committee’s view on the appropriateness of the Special Committee and the possibility of a conflict between Mr. DeMarco, due to his affiliation with Stadium Capital, and other stockholders.

On February 4, 2015, Mr. DeMarco sent a letter to Mr. Miller. The letter reiterates that there is no conflict between Stadium Capital and the other non-management stockholders of the Company. The letter also described the conflicts of other directors that were not taken into account in connection with the formation of the Special Committee, including that one of the directors, G. Michael Brown, is a partner of a law firm to which the Company’s management has directed millions of dollars in legal fees over the last several years.

On March 17, 2015, SCP delivered to the Company a formal notice of its nomination of the Nominees, as required by the Bylaws. Stadium Capital also issued a press release concerning its nomination of the Nominees.

On March 31, 2015, and following discussions with certain members of the Board, including Mr. Miller, Mr. DeMarco, on behalf of Stadium Capital, sent a proposal to the Board to resolve the proxy contest. Stadium Capital’s proposal provided for, among other things, certain changes in the composition of the Board and implementation of the governance changes that Mr. DeMarco discussed with the Board in October 2014. After discussion, the Company and Stadium Capital were not able to reach agreement.

On April 2, 2015, the Company sent a proposal to Stadium Capital to resolve the proxy contest. The Company’s proposal provided for, among other things, (1) the Board’s nominees for director at the Annual Meeting including Mr. DeMarco and a nominee chosen by the Board’s Nominating and Corporate

Governance Committee from candidates identified by Stadium Capital, another significant stockholder and a nationally-recognized director search firm retained by the Company; (2) the addition of an eighth director following the Annual Meeting, which director would be chosen by the Board’s Nominating and Corporate Governance Committee from candidates identified by Stadium Capital, another significant stockholder and a nationally-recognized director search firm retained by the Company; (3) the submission to stockholders at the 2016 Annual Meeting of a binding proposal to declassify the Board on a rolling basis if Stadium Capital’s proposal to declassify the Board passed at the Annual Meeting; (4) non-binding stockholder votes on majority voting in director elections and the elimination of the supermajority vote requirements in the Charter and Bylaws at the Annual Meeting and binding votes at the 2016 Annual Meeting if such proposals passed; and (5) the formation of a new committee of the Board focused on developing an operating improvement plan for the business and identifying possible areas of value creation.

On April 3, 2015, Mr. DeMarco, on behalf of Stadium Capital, made a counterproposal to the Company that provided for (1) the Board’s nominees for director at the Annual Meeting including Mr. DeMarco and one of the other Nominees; (2) the addition of an eighth director following the Annual Meeting, which director would be chosen by the Board’s Nominating and Corporate Governance Committee from candidates identified by Stadium Capital and a nationally-recognized director search firm retained by the Company; (3) the Board recommending that stockholders vote in favor of Stadium Capital’s proposal to declassify the Board at the Annual Meeting and the submission to stockholders at the 2016 Annual Meeting of a binding proposal to declassify the Board on a rolling basis if the proposal passed at the Annual Meeting; (4) the Board recommending that stockholders vote in favor of non-binding stockholder votes on majority voting in director elections and the elimination of the supermajority vote requirements in the Charter and Bylaws at the Annual Meeting, with the Board (a) adopting majority voting within 30 days after the Annual Meeting (if the majority voting proposal passed at the Annual Meeting); and (b) giving stockholders a binding vote at the 2016 Annual Meeting (if the elimination of supermajority provision proposal passed at the Annual Meeting); and (5) Mr. DeMarco serving as chairman of the operations and value creation committee proposed by the Company. The Company rejected this proposal on April 3, 2015.

On April 10, 2015, the Company sent a new proposal to Stadium Capital to resolve the proxy contest. The Company’s proposal provided for, among other things, (1) the Board’s nominees for director at the Annual Meeting including Mr. DeMarco and, subject to the approval of the Board’s Nominating and Corporate Governance Committee, one of the other Nominees; (2) the addition of an eighth director following the Annual Meeting; (3) certain changes to the composition of the Board’s committees; (4) the Board recommending that stockholders vote in favor of Stadium Capital’s proposal to declassify the Board at the Annual Meeting and the submission to stockholders at the 2016 Annual Meeting of a binding proposal to declassify the Board on a rolling basis if the proposal passed at the Annual Meeting; (4) non-binding stockholder votes on majority voting in director elections and the elimination of the supermajority vote requirements in the Charter and Bylaws at the Annual Meeting, with the Board (a) adopting majority voting within 30 days after the Annual Meeting (if the majority voting proposal passed at the Annual Meeting); and (b) giving stockholders a binding vote at the 2016 Annual Meeting (if the elimination of supermajority provision proposal passed at the Annual Meeting); and (5) the formation of the operations and value creation committee proposed by the Company.

On April 11, 2015, Mr. DeMarco, on behalf of Stadium Capital, made a counterproposal to the Company that largely accepted the Company’s proposal but provided for (1) the Board’s nominees for director at the Annual Meeting including Mr. DeMarco and one of the other Nominees; (2) the eighth director being recommended by a nationally-recognized director search firm retained by the Company and mutually acceptable to the Board’s Nominating and Corporate Governance Committee and Stadium Capital; (3) Mr. DeMarco and the other Nominee serving on all current and future Board Committees (other than the Audit Committee); and (4) Mr. DeMarco serving as chairman of the operations and value creation committee proposed by the Company. The Company did not accept this proposal.

Over the next several days, representatives of Stadium Capital and the Company engaged in numerous conversations and attempted to negotiate a settlement agreement, all in an effort to resolve the proxy contest.

PROPOSAL 1 — ELECTION OF DIRECTORS

The Company has disclosed that three directors are standing for election at the Annual Meeting. Accordingly, at the Annual Meeting, the three nominees who receive the greatest number of  “FOR” votes (among votes properly cast in person or by proxy) will be elected as Class A directors for terms expiring at the 2018 Annual Meeting and until their respective successors have been duly elected and qualified. Stadium Capital is seeking your support at the Annual Meeting to elect the Nominees, Dominic P. DeMarco, Nicholas Donatiello, Jr. and Michael J. McConnell.

The Nominees have furnished the following information regarding their principal occupations and certain other matters. The ages of the nominees are given as of March 17, 2015. Each of the nominees is a citizen of the United States of America.

Dominic P. DeMarco, age 44, has served as a director of the Company since October 2011. Mr. DeMarco currently serves as Managing Director, Co-Chief Investment Officer and Chief Compliance Officer for SCM, where he shares responsibility for all aspects of firm management, including managing the firm’s investment process.

Stadium Capital believes that Mr. DeMarco has extensive financial expertise and knowledge of investment banking and corporate finance, including capital allocation, which is of substantial value to the Board. In addition, Mr. DeMarco adds a unique element to the Board as an officer of the Company’s largest institutional stockholder, allowing the Board to receive ongoing feedback from the perspective of a major outside stockholder, but with a more intimate and ongoing knowledge of the Company’s operations.

STADIUM CAPITAL URGES YOU TO VOTE FOR THE ELECTION OF THE NOMINEES, Dominic P. DeMarco, Nicholas Donatiello, Jr. and Michael J. McConnell, ON THE ENCLOSED WHITE PROXY CARD TODAY.

Even if all of the Nominees are elected, they will not constitute a majority of the Board. The Nominees will not alone be able to cause the Company to take any action. However, the Nominees expect to be able to actively engage other Board members in full discussion of the issues facing the Company and resolve them together. By utilizing their respective experiences and working constructively with the other Board members, the Nominees believe that they can effect positive change at the Company.

There can be no assurance that if any of the Nominees are elected any other members of the Board who are not the Nominees will serve with such Nominees.

Except as set forth in this Proxy Statement, Stadium Capital believes that each Nominee is independent within the meaning of the rules of The NASDAQ Stock Market and is not currently affiliated with the Company or any of its subsidiaries. The Director Qualifications and Nominations and Stockholder Communications Policy of the Company, which is available on the Company’s website at http://www.big5sportinggoods.com/store/company/Investor+Relations, provides that a director qualifies as independent if  (a) the Board affirmatively determines that the director has no relationship with the Company that would impair that director’s independence; and (b) the director is not otherwise considered non-independent according to applicable rules of The NASDAQ Stock Market. Stadium Capital has no knowledge of any facts that would prevent the determination that each of the Nominees is independent in accordance with the corporate governance standards of the Company and the pertinent listing standards of The NASDAQ Stock Market and any applicable legal requirement. Consequently, Stadium Capital believes

11

that if the Nominees are elected, a majority of the directors will be independent within the meaning of the rules of The NASDAQ Stock Market and there will be a sufficient number of independent directors to serve on the Board’s Audit Committee, Compensation Committee and Nominating and Governance Committee. If the Nominees are elected, the composition of the Board’s committees will be determined by the Board.

Each of the Nominees has consented to being named as a nominee in this Proxy Statement and to serve as a director of the Company if elected. Stadium Capital does not expect that any of the Nominees will be unable to stand for election to the Board or to serve as a director if elected. In the event that a vacancy in Stadium Capital’s slate of nominees should occur because any Nominee is unable to serve or for good cause will not serve, SCP may appoint a substitute candidate that it selects and the shares of Common Stock represented by the enclosed WHITE proxy card will be voted for such substitute nominee. If SCP appoints a substitute nominee, Stadium Capital will make a filing with the SEC that (1) identifies such substitute nominee; (2) discloses that such substitute nominee has consented to being named in this Proxy Statement, as supplemented, and to serve as a director of the Company if elected; and (3) includes the information with respect to such substitute nominee required to be disclosed under the SEC’s proxy rules. In the event that the Company refuses to permit a substitute nominee as contemplated by this paragraph by reason of the Company’s bylaws or otherwise, Stadium Capital reserves the right to challenge such bylaws or the application of such bylaws to such substitute nominee or take other action in an appropriate legal proceeding.

SCP reserves the right to nominate additional nominees if the Company (1) purports to increase the number of directorships; or (2) makes or announces any changes to the Company’s bylaws or takes or announces any other action that that purports to have, or if consummated would purport to have, the effect of disqualifying any of the Nominees. To the extent that the Company proposes to put up for election more than three nominees at the Annual Meeting, SCP reserves the right to nominate an equal number of additional persons, which SCP believes would be an available remedy under Delaware law in response to any attempt by the Company to interfere with the voting rights of the Company’s stockholders. Additional nominations made pursuant to the foregoing are without prejudice to the position of SCP that any attempt to change the size of the Board or disqualify any of the Nominees or any substitute or additional alternate nominees through amendments to the Company’s bylaws or otherwise would constitute unlawful manipulation of the Company’s corporate machinery. If SCP appoints an additional nominee, it will make a filing with the SEC that (1) identifies such additional nominee; (2) discloses that such additional nominee has consented to being named in this Proxy Statement, as supplemented, and to serve as a director of the Company if elected; and (3) includes the information with respect to such additional nominee required to be disclosed under the SEC’s proxy rules. SCP reserves the right to challenge any action by the Company that has, or if consummated would have, the effect of disqualifying any Nominee or substitute or additional nominee.

To the extent that only three directorships are up for election at the Annual Meeting, Stadium Capital will use proxies solicited only to vote for the Nominees (or any substitute nominee, as described above). If SCP substitutes a nominee or proposes an additional nominee, SCP will make the filings with the SEC described above. Only then will the shares of Common Stock represented by the enclosed WHITE proxy card be voted for any substitute nominee or additional nominee.

If elected, the Nominees, together with the other directors of the Company, will be responsible for managing the business and affairs of the Company. Each director of the Company has an obligation to comply with his or her fiduciary duties under Delaware law. It is possible that circumstances may arise in which the interests of Stadium Capital, on the one hand, and the interests of other stockholders of the Company, on the other hand, may differ. In that case, Stadium Capital expects the Nominees to fully discharge their fiduciary obligations to the Company and its stockholders under Delaware law.

The Nominees will not receive any compensation from Stadium Capital for their services as directors of the Company if elected. Each of the Nominees, if elected, will be entitled to receive from the Company compensation paid by the Company to its non-employee directors. The compensation currently paid by the Company to its non-employee directors is described in the Company’s definitive proxy statement filed with the SEC on [•], 2015 (the “Company Proxy Statement”).

PROPOSAL 2 — ADVISORY VOTE ON THE COMPANY’S EXECUTIVE COMPENSATION

As discussed in further detail in the Company Proxy Statement, and as required by the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Company has proposed an advisory vote to approve the compensation of the Company’s named executive officers as described in the Company Proxy Statement. This is often referred to as a “say-on-pay” vote, and provides stockholders with the ability to cast a vote with respect to the Company’s fiscal 2014 executive compensation programs and policies and the compensation paid to the named executive officers as disclosed in the Company Proxy Statement. This advisory vote on the Company’s executive compensation is not binding on the Board.

Additional information regarding this proposal is contained in the Company Proxy Statement.

Stadium Capital recommends that you vote “FOR” this proposal. Stadium Capital intends to vote its shares of Common Stock “FOR” this proposal.

PROPOSAL 3 — RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

As discussed in further detail in the Company’s proxy statement, the Audit Committee of the Board has appointed Deloitte & Touche LLP to serve as the Company’s independent auditors for fiscal 2015. The Company is submitting the appointment of Deloitte & Touche LLP for ratification by the stockholders at the Annual Meeting.

Additional information regarding this proposal is contained in the Company Proxy Statement.

Stadium Capital recommends that you vote “FOR” this proposal. Stadium Capital intends to vote its shares of Common Stock “FOR” this proposal.

PROPOSAL 4 — MAJORITY VOTING STANDARD IN DIRECTOR ELECTIONS

As discussed in further detail in the Company’s proxy statement, the Company is conducting an advisory vote to determine the views of stockholders regarding potential adoption of a majority voting standard for uncontested elections of directors.

Additional information regarding this proposal is contained in the Company Proxy Statement.

Stadium Capital believes that, as a matter of good corporate governance, directors should be elected by majority vote. Stadium Capital recommends that you vote “FOR” this proposal. Stadium Capital intends to vote its shares of Common Stock “FOR” this proposal.

PROPOSAL 5 — ELIMINATION OF SUPERMAJORITY PROVISIONS

As discussed in further detail in the Company’s proxy statement, the Company is conducting an advisory vote to determine the views of stockholders regarding the potential elimination of certain supermajority voting provisions in the Charter and Bylaws.

Additional information regarding this proposal is contained in the Company Proxy Statement.

Stadium Capital believes that, as a matter of good corporate governance, the Company’s supermajority provisions should be eliminated. Stadium Capital recommends that you vote “FOR” this proposal. Stadium Capital intends to vote its shares of Common Stock “FOR” this proposal.

PROPOSAL 6 — STOCKHOLDER PROPOSAL REQUESTING A DECLASSIFIED BOARD

Stadium Capital submitted the following stockholder proposal and supporting statement. This proposal urges the Board to take all necessary steps (other than any steps that must be taken by the stockholders) to eliminate the classification of the Board and to require that all directors elected after the Annual Meeting be elected on an annual basis.

Proposal to Repeal Classified Board

RESOLVED, that the stockholders of Big 5 Sporting Goods Corporation (“BGFV”) urge the Board of Directors to take all necessary steps (other than any steps that must be taken by stockholders) to eliminate the classification of the Board of Directors and to require that all directors elected at or after the annual meeting held in 2016 be elected on an annual basis. Implementation of this proposal should not prevent any director elected prior to the annual meeting held in 2016 from completing the term for which such director was elected.

Supporting Statement

This resolution was submitted by Stadium Capital Management, LLC (“SCM”), one of the largest stockholders of BGFV.

The resolution urges the Board of Directors to facilitate a declassification of the Board. Having directors stand for elections annually makes directors more accountable to stockholders, and could thereby contribute to improving performance and increasing firm value. As far back as 2003, ISS argued that “the only real motive for board classification is to make it more difficult to change control of the board. A classified board can (1) delay a takeover desired by shareholders but opposed by management, and (2) prevent bidders from even approaching a target company if they do not want to wait more than a year to gain majority control. Shareholders lose in both cases, and management has less incentive to keep shares fully valued if the directors’ board seats are secure.” ISS continued to advise voting FOR proposals to repeal classified boards in its 2014 U.S. Proxy Voting Summary Guidelines.

According to data from the ISS 2014 Proxy Season Review:

•

More than 140 companies brought management proposals to declassify their boards to a vote at annual meetings during the 2013 and 2014 “proxy seasons”;

​

•

More than 45 precatory declassification proposals were put on the ballot by stockholders during this period; and

​

•

The average percentage of votes cast in favor of stockholder proposals to declassify the boards of U.S. companies exceeded 80% in each year, with 2014’s 84% average support constituting a record.

​

The significant stockholder support for declassification proposals is consistent with empirical studies reporting that:

•

Classified boards are associated with lower firm valuation (Bebchuk and Cohen, 2005; confirmed by Faleye (2007) and Frakes (2007));

​

•

Takeover targets with classified boards are associated with lower gains to stockholders (Bebchuk, Coates and Subramanian, 2002);

​

•

Firms with classified boards are more likely to be associated with value-decreasing acquisition decisions (Masulis, Wang and Xie, 2007); and

​

•

Classified boards are associated with lower sensitivity of compensation to performance and lower sensitivity of CEO turnover to firm performance (Faleye, 2007).

​

There are academic studies that reach opposing conclusions. For example, one study (Bates, Becher and Lemmon, 2008) reports that classified boards are associated with higher takeover premiums; however, this study also reports that classified boards are associated with a lower likelihood of an acquisition and that classified boards are associated with lower firm valuation.

Please vote “FOR” this proposal to make directors more accountable to stockholders.

Stadium Capital believes that, as a matter of good corporate governance, all directors should be elected annually. Stadium Capital recommends that you vote “FOR” this proposal. Stadium Capital intends to vote its shares of Common Stock “FOR” this proposal.

VOTING AND PROXY PROCEDURES

Securities Entitled to Vote

Based on information publicly disclosed by the Company, the shares of Common Stock constitute the only class of outstanding voting securities of the Company. Accordingly, only holders of shares of Common Stock as of the close of business on the Record Date are entitled to vote at the Annual Meeting. Each share of Common Stock entitles its holder to one vote. There are no cumulative voting rights. The Company has disclosed that [•] shares of Common Stock were outstanding and entitled to vote as of the close of business on the Record Date. If you are a stockholder of record as of the Record Date, you will retain your right to vote at the Annual Meeting even if you sell your shares of Common Stock after the Record Date.

Quorum

The presence, in person or by proxy, of holders of a majority of the shares of Common Stock entitled to vote at the Annual Meeting is necessary to constitute a quorum. Your shares of Common Stock will be counted toward the quorum only if you submit a valid proxy (or one is submitted on your behalf by your bank, brokerage firm, dealer, trust company or other nominee) or if you vote in person by ballot at the Annual Meeting. Abstentions, broker non-votes and votes withheld will be counted toward the quorum requirement. If a quorum is not present or represented at the Annual Meeting, the chairman of the meeting may adjourn the Annual Meeting to another place, if any, date or time.

Vote Required

Directors of the Company are elected by a plurality of all the votes cast at the Annual Meeting, assuming a quorum is present. For this purpose, “plurality” means that the individuals receiving the greatest number of votes are elected as directors, up to the maximum number of directors to be elected. The Company has disclosed that three directors are standing for election at the Annual Meeting. Accordingly, at the Annual Meeting, the three nominees who receive the greatest number of  “FOR” votes (among votes properly cast in person or by proxy) will be elected as Class A directors for terms expiring at the 2018 Annual Meeting and until their successors have been duly elected and qualified. A signed proxy that withholds authority with respect to the election of any or all nominees will be counted for purposes of determining whether there is a quorum, but, with respect to any specific nominee, will not be considered to have been voted for such nominee. Broker non-votes, if any, are not considered votes cast and will result in the applicable nominee receiving fewer “FOR” votes for purposes of determining the three nominees receiving the most votes.

By voting using the enclosed WHITE proxy card, you will only be able to vote for the Nominees. If you wish to vote for a different slate of nominees, you will need to return the Company’s [color] proxy card or attend the Annual Meeting in person and vote by ballot. If your shares of Common Stock are held in “street name” in the name of a bank, brokerage firm, dealer, trust company or other nominee, you will not be able to vote in person by ballot at the Annual Meeting unless you have previously requested and obtained a “legal proxy” from your bank, brokerage firm, dealer, trust company or other nominee and present it at the Annual Meeting.

With respect to any proposal other than the election of directors that properly comes before the Annual Meeting, assuming a quorum is present, such proposal requires a “FOR” vote from the majority of the votes cast, affirmatively or negatively, on such proposal at the Annual Meeting. Abstentions and broker non-votes, if any, will be disregarded and have no effect on the outcome of the vote.

Stadium Capital currently intends to deliver this Proxy Statement and a WHITE proxy card to a sufficient number of holders of shares of Common Stock to elect the Nominees.

Pursuant to applicable SEC rules, the Company is required to announce the preliminary or final voting results within four business days of the Annual Meeting by means of a Current Report on Form 8-K filed with the SEC.

15

Voting by Proxy

Please authorize a proxy to vote by signing, dating and returning the enclosed WHITE proxy card in the postage-paid envelope provided TODAY.

If you hold your shares of Common Stock in more than one account, you will receive a WHITE proxy card for each account. To ensure that all of your shares of Common Stock are voted, please sign, date and return the WHITE proxy card for each account.

YOUR VOTE IS VERY IMPORTANT. If you do not plan to attend the Annual Meeting, Stadium Capital encourages you to vote the enclosed WHITE proxy card today so that your shares of Common Stock will be represented and voted in accordance with your instructions. Even if you plan to attend the Annual Meeting in person, Stadium Capital recommends that you vote your WHITE proxy card so that your vote will be counted if you later decide not to attend the Annual Meeting.

The enclosed WHITE proxy card may be signed only by holders of record of shares of Common Stock as of the close of business on the Record Date. If you were a stockholder of record as of the close of business on the Record Date, you will retain your voting rights at the Annual Meeting even if you sell some or all of your shares of Common Stock after the Record Date. Accordingly, it is important that you vote all of the shares of Common Stock held by you as of the close of business on the Record Date, or grant a proxy to vote your shares of Common Stock on the enclosed WHITE proxy card, even if you sell some or all of your shares of Common Stock after the Record Date.

If you are a beneficial owner of shares of Common Stock held in “street name” in the name of a bank, brokerage firm, dealer, trust company or other nominee, these proxy materials are being forwarded to you by your bank, brokerage firm, dealer, trust company or other nominee. As a beneficial owner, you must instruct your broker, dealer, trustee or nominee how to vote. Your broker, dealer, trustee or nominee cannot vote your shares of Common Stock on your behalf without your instructions.

If you are a beneficial owner of shares of Common Stock held in “street name” and do not provide voting instructions to your bank, brokerage firm, dealer, trust company or other nominee, your shares of Common Stock will not be voted on any proposal on which your bank, brokerage firm, dealer, trust company or other nominee does not have or does not exercise discretionary authority to vote, such as a non-routine matter for which you do not provide voting instructions. This is referred to as a “broker non-vote.” Stadium Capital believes that due to the contested nature of the election at the Annual Meeting, all of the matters to be voted on at the Annual Meeting are considered non-routine. Accordingly, banks, brokerage firms, dealers, trust companies and other nominees will be unable to exercise discretionary voting authority with respect to any of the proposals to be voted on at the Annual Meeting.

Depending upon your bank, brokerage firm, dealer, trust company or other nominee, you may be able to vote either by telephone or over the Internet. Please refer to the enclosed WHITE voting instruction form for instructions on how to vote electronically. You may also vote by signing, dating and returning the enclosed WHITE voting instruction form.

Because a beneficial owner is not the stockholder of record, if you wish to vote your shares of Common Stock in person by ballot at the Annual Meeting, you must obtain a “legal proxy” from the bank, brokerage firm, dealer, trust company or other nominee that holds your shares of Common Stock.

IMPORTANT

Regardless of how many shares of Common Stock you own, your vote is very important. Please vote by signing, dating and returning the enclosed WHITE proxy card.

Please vote each WHITE proxy card that you receive as each account must be voted separately.

Do not return any blue proxy card that you may receive from the Company, even as a protest vote. If you have already submitted a blue proxy card, it is not too late to change your vote. To revoke your prior proxy and change your vote, simply sign, date and return the enclosed WHITE proxy card in the postage-paid envelope provided. Only your latest signed and dated proxy will be counted.

16

Attending the Annual Meeting

You are entitled to attend the Annual Meeting if you are a stockholder of record as of the close of business on the Record Date.

If you are a beneficial owner of shares of Common Stock held in “street name” in the name of a bank, brokerage firm, dealer, trust company or other nominee, your name will not appear in the Company’s register of stockholders. Those shares of Common Stock are held in the name of your bank, brokerage firm, dealer, trust company or other nominee on your behalf. In order for you to attend the Annual Meeting, you must bring a letter or account statement showing that you beneficially own the shares of Common Stock held by your bank, brokerage firm, dealer, trust company or other nominee. To ensure that your shares of Common Stock are voted at the Annual Meeting, you should promptly give instructions to your bank, brokerage firm, dealer, trust company or other nominee to ensure that a WHITE proxy card is submitted on your behalf.

Please refer to the Company Proxy Statement for additional information about attending the Annual Meeting, including any requirements to gain admission to the Annual Meeting.

Revocation of Proxies

If you are a record owner of shares of Common Stock as of the close of business on the Record Date and have mailed a proxy card to the Company, you may revoke that card before it is voted at the Annual Meeting by mailing a signed WHITE proxy card bearing a date later than the proxy card that you delivered to the Company either to Stadium Capital in care of Morrow & Co., LLC, 470 West Avenue, Stamford, CT 06902, or to such address as the Company may provide. Only your latest signed and dated proxy will count and will serve as a revocation of any prior proxy submitted. Proxies may also be revoked at any time prior to being voted at the Annual Meeting by: (1) attending the Annual Meeting and voting in person by ballot (attendance at the Annual Meeting will not in and of itself constitute revocation of a proxy); or (2) delivering a written notice of revocation. A written revocation may be in any form validly signed by the record holder or an authorized agent of the record holder as long as it clearly states that the proxy previously given is no longer effective. A written notice of revocation may be delivered either to Stadium Capital in care of Morrow & Co., LLC, 470 West Avenue, Stamford, CT 06902, or to such address as the Company may provide. Although a revocation is effective if delivered to the Company, Stadium Capital requests that you mail or deliver either the original or a copy of any revocation to Stadium Capital in care of Morrow & Co., LLC, 470 West Avenue, Stamford, CT 06902 at the address above. Stadium Capital may contact stockholders who have revoked their proxies.

If your shares of Common Stock are held in “street name” in the name of a bank, brokerage firm, dealer, trust company or other nominee and you wish to revoke a proxy card, you must return a later dated proxy to your bank, brokerage firm, dealer, trust company or other nominee. Only your latest signed and dated proxy will count. You may also revoke a proxy at any time before it is voted at the Annual Meeting by attending the Annual Meeting and voting in person by ballot (attendance at the Annual Meeting will not in and of itself constitute revocation of a proxy). You will also need to obtain a “legal proxy” from the bank, brokerage firm, dealer, trust company or other nominee that holds your shares of Common Stock in order to vote in person by ballot at the Annual Meeting.

By submitting your proxy to Stadium Capital by signing and dating the enclosed WHITE proxy card, you are revoking all prior proxies that you have previously given with respect to the Annual Meeting.

SOLICITATION OF PROXIES

The initial solicitation of proxies by mail may be supplemented by telephone, fax, email, newspapers and other publications of general distribution, through the Internet, and by other electronic communication and personal solicitation by Stadium Capital and the persons listed on Annex A who are “participants” in the solicitation of proxies. No additional compensation for soliciting proxies will be paid to such participants for their proxy solicitation efforts.

17

Stadium Capital has retained Morrow & Co. LLC (“Morrow”) for solicitation and advisory services in connection with the solicitation of proxies, for which Morrow is to receive a fee of up to $125,000. Up to 50 people may be employed by Morrow in connection with the solicitation of proxies. Stadium Capital has also agreed to reimburse Morrow for out-of-pocket expenses and to indemnify Morrow against certain liabilities and expenses, including reasonable legal fees and related charges. Morrow will solicit proxies from individuals, banks, brokerage firms, dealers, trust companies, other nominees and other institutional holders.

Stadium Capital’s expenses related to the solicitation of proxies are currently estimated to be approximately $1,000,000, of which approximately $100,000 has been incurred to date. Such costs include, among other things, expenditures for attorneys, public relations advisors, proxy solicitors, printing, advertising, postage and other miscellaneous expenses and fees. The entire expense of soliciting proxies by or on behalf of Stadium Capital is being borne by Stadium Capital. Bank, brokerage firms, dealers, trust companies and other nominees will be requested to forward solicitation materials to beneficial owners of shares of Common Stock. Stadium Capital will reimburse banks, brokerage firms, dealers, trust companies and other nominees for their reasonable expenses for sending solicitation material to beneficial owners.

To the extent legally permissible, if successful in the election of one or more of the Nominees, Stadium Capital currently intends to seek reimbursement from the Company for the costs of this solicitation. Stadium Capital does not currently intend to submit the question of such reimbursement to a vote of the stockholders of the Company.
