PROXY STATEMENT

2020 ANNUAL MEETING OF STOCKHOLDERS

OF

POTBELLY CORPORATION

This proxy statement and accompanying GOLD proxy card are being furnished to stockholders of Potbelly Corporation, a Delaware corporation (“Potbelly” or the “Company”), by Vann A. Avedisian Trust U/A 8/29/85 (the “Vann Trust”), Intrinsic Investment Holdings, LLC (“IIH”), KGT Investments, LLC (“KGT”), The Khimji Foundation (“TKF”), Mahmood Khimji, Vann A. Avedisian, Bryant L. Keil and Neil Luthra (collectively, the “Investors,” “we,” “our” or “us”) and their nominees listed below in connection with the solicitation of proxies from the holders (the “Stockholders”) of common stock, $0.01 par value, of the Company (the “Common Stock”), in connection with the 2020 annual meeting of Stockholders (including any and all adjournments, postponements, continuations or reschedulings thereof, or any other meeting of Stockholders held in lieu thereof, the “2020 Annual Meeting”).

The Company has not yet announced the date, time or location of the 2020 Annual Meeting, although the Company’s annual meeting of Stockholders has previously been held in May. Similarly, the Company has not yet announced the record date for determining Stockholders entitled to notice of and to vote at the 2020 Annual Meeting (the “Record Date”). In the event that we distribute our definitive proxy statement before the Company files the Company’s Proxy Statement, we will provide any previously omitted information in a supplement filed as a revised definitive proxy statement, including completing references to the date, time and location of the 2020 Annual Meeting.

THIS SOLICITATION IS BEING MADE BY THE INVESTORS AND NOT ON BEHALF OF THE BOARD OF DIRECTORS OF THE COMPANY (THE “BOARD”).

This proxy statement and the accompanying GOLD proxy card are first being sent or given on or about [                ], 2020 to all Stockholders as of the Record Date.

We are soliciting your vote because we believe that the election of Vann A. Avedisian, David J. Near and Todd W. Smith (collectively, our “Nominees”) would contribute significantly to the Board and Potbelly’s value creation for its Stockholders.

Each of the Investors and each Nominee are “participants” under U.S. Securities and Exchange Commission (“SEC”) rules in this solicitation.

THE NOMINEES ARE COMMITTED TO ACTING IN THE BEST INTERESTS OF ALL STOCKHOLDERS. WE BELIEVE THAT YOUR VOICE IN THE FUTURE OF POTBELLY CAN BEST BE EXPRESSED THROUGH THE ELECTION OF OUR NOMINEES. ACCORDINGLY, THE PARTICIPANTS URGE YOU TO VOTE YOUR GOLD PROXY CARD “FOR” VANN A. AVEDISIAN, DAVID J. NEAR AND TODD W. SMITH AS DIRECTORS.

Except as set forth in this proxy statement, including the ratification of the appointment of the Company’s independent registered public accounting firm, the possible proposal to approve, on an advisory basis, the frequency of future advisory votes on the compensation of the Company’s named executive officers, and the possible proposal to approve, on an advisory basis, the compensation of the Company’s named executive officers, we do not know of any other matters to be presented for approval by the Stockholders at the 2020 Annual Meeting. If, however, the Investors learn of any other proposals made at a reasonable time before the 2020 Annual Meeting, the Investors will either supplement this proxy statement and provide Stockholders with an opportunity to vote by proxy directly on such matters, or will not exercise discretionary authority with respect thereto. If other matters are properly presented thereafter, the persons named as proxies in the enclosed GOLD proxy card will vote the shares of Common Stock represented thereby in accordance with their discretion pursuant to the authority granted in the proxy.

We believe that substantial change is necessary for the Company to achieve its full potential and that this change must begin at the Board level. To that end, the Investors have nominated three highly qualified nominees with relevant restaurant operating and financial experience who we believe would bring critical skills and invaluable perspective to the Board’s decision-making process. They are committed to helping identify opportunities to deliver enhanced value. We would expect these opportunities to include, but not be limited to, restoring the Potbelly customer experience that has been largely lost, simplifying the menu, modernizing and decluttering restaurants, improving associate hiring and training processes, transforming marketing, improving product consistency and executing franchise agreements with leading multi-unit operators. While no assurances can be given that the election of our Nominees will enhance value, particularly in light of their minority representation on the Board, we believe that the election of our Nominees will send a strong message from Stockholders that they are supportive of transformative change at Potbelly rather than the status quo. We therefore urge you to support us in this effort by voting “FOR” our Nominees.

We recommend that you vote your shares on the GOLD proxy card as follows:

The accompanying GOLD proxy card provisionally includes proposals (i) to ratify the appointment of Deloitte (or such other independent registered public accounting firm as may be appointed by the Company’s audit committee and set forth in the Company’s proxy statement for the 2020 Annual Meeting) as the Company’s independent registered public accounting firm for 2020, (ii) to approve, on an advisory basis, the frequency of future advisory votes on the compensation of the Company’s named executive officers, and (iii) to approve, on an advisory basis, the compensation of the Company’s named executive officers as may be disclosed in the Company’s proxy statement for the 2020 Annual Meeting; however, the GOLD proxy card can only be voted on the proposals if any such proposal is actually presented at the 2020 Annual Meeting. We recommend a vote for annual “say on pay” votes and intend to vote our shares of Common Stock for “ONE YEAR” on this proposal. [We recommend a vote [“FOR”/“AGAINST”] the other matters and intend to vote our shares of Common Stock [“FOR”/“AGAINST”] the related proposals.]

Under the proxy rules, we may solicit proxies in support of our Nominees and also seek authority to vote for all of the Company’s nominees other than those Company nominees we specify. This allows a Stockholder who desires to vote for up to a full complement of eight director nominees to use the GOLD proxy card to vote for our Nominees as well as the Company’s nominees for whom we are seeking authority to vote. We have determined to nominate a slate of three Nominees, Vann A. Avedisian, David J. Near and Todd W. Smith, and are seeking authority to vote for up to all of the Company’s nominees other than [                ], [                ] and [                ]. As a result, should a Stockholder so authorize us on the GOLD proxy card, we would cast votes for our three

- ii -

Nominees and for up to five of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote has agreed to serve with any of our Nominees, if elected, and there is no assurance that any of the Company’s nominees will serve as directors if any or all of our Nominees are elected to the Board.

The principal executive offices of the Company are located at 111 North Canal Street, Suite 850, Chicago, Illinois 60606.

The Company has disclosed that as of January 26, 2020, there were 23,638,157 shares of Common Stock outstanding. The Company’s proxy statement for the 2020 Annual Meeting will provide the current number of shares of Common Stock outstanding and entitled to vote at the 2020 Annual Meeting. Each share of Common Stock is entitled to one vote on all matters presented at the 2020 Annual Meeting.

We intend to vote all of the shares of Common Stock that we beneficially own at the 2020 Annual Meeting: “FOR” the election of the election of our Nominees and to grant authority to vote for the Company’s nominees other than [                ], [                ] and [                ]. The accompanying GOLD proxy card provisionally includes proposals (i) to ratify the appointment of Deloitte (or such other independent registered public accounting firm as may be appointed by the Company’s audit committee and set forth in the Company’s proxy statement for the 2020 Annual Meeting) as the Company’s independent registered public accounting firm for 2020, (ii) to approve, on an advisory basis, the frequency of future advisory votes on the compensation of the Company’s named executive officers, and (iii) to approve, on an advisory basis, the compensation of the Company’s named executive officers as may be disclosed in the Company’s proxy statement for the 2020 Annual Meeting; however, the GOLD proxy card can only be voted on the proposals if any such proposal is actually presented at the 2020 Annual Meeting. We recommend a vote for annual “say on pay” votes and intend to vote our shares of Common Stock for “ONE YEAR” on this proposal. [We recommend a vote [“FOR”/“AGAINST”] the other matters and intend to vote our shares of Common Stock [“FOR”/“AGAINST”] the related proposals.]

This proxy solicitation is being made by the Investors and the Nominees and not on behalf of the Board or the Company’s management.

BACKGROUND TO THIS SOLICITATION

The following is a chronology of material events leading up to this proxy solicitation:

- 2 -

Later that day, the Investors filed with the SEC a preliminary proxy statement (the “Preliminary Proxy Statement”) for the solicitation of proxies in connection with their nomination of Vann A. Avedisian, David J. Near and Todd W. Smith for election at the 2020 Annual Meeting. The selection of the three Nominees to an eight member Board was intended to be less disruptive to the cohesion of the Board while at the same time still proposing candidates with the restaurant operating and turnaround experience which the Investors believe is necessary to effect the changes required at the Company.

REASONS FOR THE SOLICITATION

For 2019, Restaurant Business Magazine listed Potbelly as the worst performing publicly traded restaurant stock. Same-store sales continued their decline and ended 2019 with twelve consecutive quarters of decline. As Stockholders, the only news we get about Potbelly is bad news: revenue down, same store sales down, stores closing and stock price down over 90% since October 2013.

We believe the last two CEOs led the Company down the wrong path for years and did not understand the Potbelly brand. Furthermore, we believe that the current CEO does not have a viable plan to fix Potbelly’s problems. The strategy that has been deployed is the playbook for a large national quick service restaurant brand. We do not believe this is appropriate for Potbelly. The Potbelly playbook has been characterized by limited-time offers, menu proliferation, and badly executed marketing and advertising campaigns.

Potbelly’s attempts to attract non-core customers with added offerings and bundling of products have alienated Potbelly’s core, once-loyal customer base by slowing throughput and minimizing the customer experience. Store associates are burdened by increasingly complicated and constantly changing offerings, and are unable to provide the warm, lively and impeccably maintained environment that was the Potbelly experience. In addition, we believe there has been a continual decline in restaurant cleanliness and maintenance. We believe that this ongoing mismanagement has driven away the discerning core customer that Potbelly badly needs and once attracted.

Each initiative launched by management has, in our opinion, failed because it did not leverage Potbelly’s greatest assets: highly loyal customers, a great customer experience and store atmosphere, delicious sandwiches, milkshakes, soups, fresh cookies, and the opportunity to explore new and innovative drinks and products. Instead, the current management team has greatly complicated the operation, slowed throughput and priced Potbelly out of one of its core strategic advantages: great food and value prices in a “non-fast food” environment.

Management’s “store of the future” is further evidence that they just do not understand the Potbelly brand – it does not, in our opinion, resemble the high-quality Potbelly store that customers have historically expected and embraced. We believe the ongoing mismanagement has caused Potbelly to shed customers in an increasingly competitive environment and that current management has failed to recognize, and is thus unable to fix, the core problems with the operation.

Two years after the current CEO assumed his position as CEO, the Board spent $3 million on a third-party consultant to build a management strategy. If the current CEO does not understand the core strengths of Potbelly and how to run the stores and requires a $3 million consultancy, then in our opinion he is not the right person to turn the Company around. We are confident that if the current CEO continues on his current course, then the value that still remains in Potbelly will be irredeemably impaired.

We believe that substantial change is necessary for Potbelly to achieve its full potential and that this change must begin at the Board level. Only one out of seven of Potbelly’s current independent directors has recent restaurant operating experience. To that end, the Investors have nominated three highly qualified nominees with relevant restaurant operating and financial experience who we believe would bring critical skills and invaluable perspective to the Board’s decision-making process. If elected, these nominees have identified opportunities to deliver enhanced value and attract management – level professionals with deep restaurant operating and turnaround experience.

We expect the nominees to focus on:

- 4 -

If elected, the Nominees would be a minority of the directors and would not alone be able to adopt resolutions or otherwise cause the Board to act on the opportunities they identify. However, the Nominees intend to work actively with the other Board members to discuss these opportunities and resolve them together.

By voting “FOR” our Nominees at the 2020 Annual Meeting, Stockholders will send a clear message that the Company’s Board and management team need to act decisively and immediately to save Potbelly and restore the tremendous shareholder value in Potbelly that has been squandered.

QUESTIONS AND ANSWERS RELATING TO THIS PROXY SOLICITATION

The following are some of the questions you may have as a Stockholder, as well as the answers to those questions. The following is not a substitute for the information contained in this proxy statement, and the information contained below is qualified in its entirety by the more detailed descriptions and explanations contained elsewhere in this proxy statement. We urge you to read this proxy statement carefully and in its entirety.

Who is making this solicitation?

The solicitation for election of the Nominees and the other proposals described in this proxy statement at the 2020 Annual Meeting is being made by the Investors and the Nominees. For more information regarding the Investors and the Nominees in this solicitation, please see Annex A attached to this proxy statement.

What are we asking you to vote for?

We are asking you to vote on the GOLD proxy card at the 2020 Annual Meeting as follows:

The accompanying GOLD proxy card provisionally includes proposals (i) to ratify the appointment of Deloitte (or such other independent registered public accounting firm as may be appointed by the Company’s audit committee and set forth in the Company’s proxy statement for the 2020 Annual Meeting) as the Company’s independent registered public accounting firm for 2020, (ii) to approve, on an advisory basis, the frequency of future advisory votes on the compensation of the Company’s named executive officers, and (iii) to approve, on an advisory basis, the compensation of the Company’s named executive officers as may be disclosed in the Company’s proxy statement for the 2020 Annual Meeting; however, the GOLD proxy card can only be voted on the proposals if any such proposal is actually presented at the 2020 Annual Meeting. We recommend a vote for annual “say on pay” votes and intend to vote our shares of Common Stock for “ONE YEAR” on this proposal. [We recommend a vote [“FOR”/“AGAINST”] the other matters and intend to vote our shares of Common Stock [“FOR”/“AGAINST”] the related proposals.]

Please see the sections entitled “Proposal 1: Election of Nominees,” “Proposal 2: Ratification of the Appointment of Deloitte as the Company’s Independent Registered Public Accounting Firm,” “Proposal 3: Advisory Vote on the Frequency of Future Advisory Votes on the Company’s Executive Compensation” and “Proposal 4: Advisory Vote to Approve the Compensation of the Company’s Named Executive Officers” for a more complete description of each of these proposals.

Why are we soliciting your vote?

We believe that Potbelly can meaningfully improve its operating performance and restore some of the shareholder value that has been squandered by bringing in three new directors with deep restaurant experience. The election of our Nominees would send a strong signal that Stockholders are supportive of transformative, value-creating change at Potbelly rather than the status quo. While no assurances can be given that the election of our Nominees to the Board will enhance value, particularly in light of their minority representation on the Board, we urge the Stockholders to support us in this effort by voting “FOR” our Nominees.

Who are our Nominees?

We are proposing that Vann A. Avedisian, David J. Near and Todd W. Smith be elected as directors of the Company to serve on the Board until the 2021 Annual Meeting or until their respective successors are duly elected and qualified.

- 6 -

Set forth below is (a) the name, age, any position and office with the Company held by each Nominee, and the term thereof, business experience during the past five years (including principal occupation and employment during the past five years, the name and principal business of any corporation or other organization in which such occupation or employment was carried on; and whether such corporation or organization is a parent, subsidiary or other affiliate of the Company), a brief discussion of the specific experience, qualifications, attributes or skills that led to the conclusion that the Nominee should serve as a director for the Company as of the date hereof, in light of the Company’s business and structure (including such material information beyond the past five years and information on the Nominee’s particular area of expertise or other relevant qualifications), and (b) any directorships held by such person during the past five years in any company with a class of securities registered pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or subject to the requirements of Section 15(d) of the Exchange Act or any company registered as an investment company under the Investment Company Act of 1940, as amended.

- 7 -

The Board currently consists of eight directors, all of whom are up for election at the 2020 Annual Meeting. This proxy statement is soliciting proxies to elect Vann A. Avedisian, David J. Near and Todd W. Smith, and to grant authority to vote for the Company’s nominees other than [                ], [                ] and [                ]. Therefore, should a Stockholder so authorize us, we will cast votes for our three Nominees and for up to five of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote has agreed to serve with any of our Nominees, if elected, and there is no assurance that any of the Company’s nominees will serve as directors if any or all of our Nominees are elected to the Board.

If elected, the Nominees would be a minority of the directors and will not alone be able to adopt resolutions or otherwise cause the Board to act. The Nominees intend to work actively with the other Board members to

- 8 -

discuss the issues and challenges facing the Company and resolve them together. By utilizing their respective experience and working constructively with the other Board members, the Nominees believe they can effect positive change at the Company.

The Company’s corporate governance guidelines, which are available on the Company’s website at http://investors.potbelly.com/static-files/bd2d60ee-0e31-4fee-b069-e033bb8cbc79 set forth guidelines to assist the Board in making a determination whether a director has a material relationship with the Company for purposes of determining independence. Based on the information furnished by the Nominees, we believe that each of the Nominees is independent and none of the Participants has any knowledge of any facts that would prevent the determination that each of the Nominees is independent.

You should refer to the Company’s proxy statement for the 2020 Annual Meeting, when it becomes available, for the names, background, qualifications and other information concerning the Company’s nominees.

Who can vote at the 2020 Annual Meeting?

According to the Company’s public filings, Common Stock is the Company’s only outstanding class of capital stock. Only stockholders of record as shown on the Company’s books at the close of business on the Record Date are entitled to vote at the 2020 Annual Meeting or any adjournment thereof. Each Stockholder is entitled to one vote per share of Common Stock on all matters to be voted on at the 2020 Annual Meeting. Holders of shares of Common Stock are not entitled to cumulative voting rights. The Company has disclosed that as of January 26, 2020, there were 23,638,157 shares of Common Stock outstanding.

Stockholders who sell their shares before the Record Date (or acquire them after the Record Date) may not vote such shares. Stockholders of record on the Record Date will retain their voting rights in connection with the 2020 Annual Meeting even if they sell their shares after the Record Date.

How do proxies work?

We are asking you to appoint [             ] as your proxy holder to vote your shares of Common Stock at the 2020 Annual Meeting. You make this appointment by voting the enclosed GOLD proxy card or by using one of the voting methods described below. Giving us your proxy means you authorize the proxy holder to vote your shares of Common Stock at the 2020 Annual Meeting according to the directions you provide. You may vote for all, some, or none of our Nominees. Regardless of whether you are able to attend the 2020 Annual Meeting, you are urged to complete the enclosed GOLD proxy card and return it in the enclosed self-addressed, prepaid envelope or by instructing us by telephone or via the Internet as to how you would like your shares of Common Stock voted (instructions are on your GOLD proxy card). All valid proxies received prior to the 2020 Annual Meeting will be voted. If you specify a choice with respect to any item by marking the appropriate box on the proxy, the shares of Common Stock will be voted in accordance with that specification.

IF YOU RETURN A VALID GOLD PROXY AND NO SPECIFICATION IS MADE, THE SHARES OF COMMON STOCK BENEFICIALLY OWNED BY YOU WILL BE VOTED: (I) “FOR” VANN A. AVEDISIAN FOR DIRECTOR; (II) “FOR” DAVID J. NEAR FOR DIRECTOR; (III) “FOR” TODD W. SMITH FOR DIRECTOR; (IV) TO GRANT AUTHORITY TO VOTE FOR THE PERSONS WHO HAVE BEEN NOMINATED BY THE COMPANY TO SERVE AS DIRECTORS, OTHER THAN [                ], [                ] AND [                ]; (V) [“FOR”/“AGAINST”] THE COMPANY’S PROPOSAL, IF PRESENTED AT THE 2020 ANNUAL MEETING, TO RATIFY THE APPOINTMENT OF DELOITTE AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR ENDING DECEMBER 31, 2020; (VI) FOR “[ONE YEAR]” ON THE COMPANY’S PROPOSAL, IF PRESENTED AT THE 2020 ANNUAL MEETING, TO APPROVE, ON AN ADVISORY BASIS, A FREQUENCY OF “[ONE YEAR]” FOR FUTURE ADVISORY VOTES ON THE COMPANY’S EXECUTIVE COMPENSATION; (VII) [“FOR”/“AGAINST”] THE COMPANY’S PROPOSAL, IF

- 9 -

PRESENTED AT THE 2020 ANNUAL MEETING, TO APPROVE, ON AN ADVISORY BASIS, THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS, AS MAY BE DESCRIBED IN THE COMPANY’S PROXY STATEMENT FOR THE 2020 ANNUAL MEETING; AND (IX) IN THE PROXY HOLDER’S DISCRETION AS TO OTHER MATTERS THAT THE INVESTORS DO NOT KNOW, A REASONABLE TIME BEFORE THE SOLICITATION, ARE TO BE PRESENTED AT THE 2020 ANNUAL MEETING.

Except as set forth in this proxy statement, we do not know of any other matters to be presented for approval by the Stockholders at the 2020 Annual Meeting. Unless you indicate otherwise on the GOLD proxy card, you also authorize your proxy holders to vote your shares of Common Stock in their discretion on any matters not known by us at the time this proxy statement was printed and that, under the Amended and Restated By-Laws of the Company (the “By-Laws”), may be properly presented for action by the Stockholders at the 2020 Annual Meeting.

What is the quorum requirement for the 2020 Annual Meeting?

In order to have a valid shareholder vote, a quorum must exist at the 2020 Annual Meeting. This means holders of at least a majority of the outstanding shares of Common Stock entitled to vote must be represented at the meeting, either by proxy or in person.

Votes withheld, abstentions and broker-non votes will be counted as present or represented for purposes of determining whether a quorum exists. In the absence of a quorum, the 2020 Annual Meeting may be adjourned by a majority of the votes entitled to be cast either present in person or represented by proxy or by any officer entitled to preside at the 2020 Annual Meeting.

What is the effect of an abstain vote?

If a Stockholder abstains from voting as to any matter, then the shares of Common Stock held by such Stockholder shall be deemed present at the meeting for purposes of determining a quorum and for purposes of calculating the vote with respect to such matter, but shall otherwise not be deemed to have been voted on such matter. As a result, an abstention on any proposal will have no effect on the outcome of any proposal, except it will have the same effect as a vote against the ratification of the Company’s independent registered accounting firm and the proposal to approve, on an advisory basis, the Company’s executive compensation (if presented at the 2020 Annual Meeting).

What is a broker non-vote?

If you are a beneficial owner of shares of Common Stock and the organization holding your account does not receive instructions from you as to how to vote those shares, under the rules of various national and regional securities exchanges, that organization may exercise discretionary authority to vote on “routine” proposals (which typically include ratification of compensation plans) but may not vote on “non-routine” proposals. However, under the current circumstances of a contested election, there are no “routine” proposals and, accordingly, if you are a beneficial owner holding shares of Common Stock through a broker and we have provided our solicitation materials to you with respect to such shares, your broker is not permitted to vote your shares of Common Stock on any proposal without receiving instructions from you. A “broker non-vote” occurs when a broker or other nominee who holds shares of Common Stock for a beneficial owner withholds its vote on a particular proposal with respect to which it does not have discretionary voting power or instructions from the beneficial owner. Broker non-votes, if any, will be deemed present at the 2020 Annual Meeting for purposes of determining whether a quorum exists for the 2020 Annual Meeting, but they will not be counted in determining the number of shares of Common Stock necessary for approval of any proposal.

- 10 -

What vote is required to elect the Nominees?

Under the By-Laws, in contested elections such as this one, the directors shall be elected by the vote of a plurality of the shares of Common Stock represented, in person or by proxy, at the 2020 Annual Meeting (meaning, assuming that the Board remains the same size as it is currently, those eight director nominees receiving the greatest number of votes cast “FOR” shall be elected). Stockholders do not have the right to cumulate their votes in the election of directors. Votes withheld are not votes cast and will result in the applicable nominees receiving fewer “FOR” votes for purposes of determining the eight nominees receiving the most votes. A properly executed proxy marked “WITHHOLD” with respect to the election of any or all director nominees will be counted for purposes of determining whether there is a quorum, but a proxy marked “WITHHOLD” with respect to any specific director nominee will not be considered to have been voted for or against such director nominee. Therefore, a proxy marked “WITHHOLD” with respect to a specific director nominee will result in such director nominee receiving fewer “FOR” votes. A Stockholder cannot abstain in the election of directors.

How many shares of Common Stock must be voted in favor of the provisional proposals described in this proxy statement?

If presented at the 2020 Annual Meeting, ratification of the appointment of Deloitte as the Company’s independent registered public accounting firm for 2020 will require the affirmative vote of a majority of the shares of Common Stock present at the 2020 Annual Meeting, in person or by proxy, and entitled to vote on the proposal at the 2020 Annual Meeting. Abstentions will have the same effect as a vote against this proposal. You may vote for or against or you may abstain on this proposal. Ordinarily, your broker does not need your voting instruction in order to vote your shares of Common Stock in connection with so-called “routine” matters, which typically include ratification of auditors. However, under the current circumstances of a contested election, if you are a beneficial owner holding shares of Common Stock through a broker and we have provided our solicitation materials to you with respect to such shares, your broker is not permitted to vote your shares of Common Stock on this proposal without receiving instructions from you. Broker non-votes would not be counted in determining the number of shares of Common Stock necessary for approval of this proposal and thus will not have a direct effect on this proposal.

If presented at the 2020 Annual Meeting, the provisional proposal to approve, on an advisory basis, the Company’s frequency of future “say on pay” votes on the Company’s executive compensation, is not binding on the Company and would be considered to have been approved if it receives the affirmative vote of a majority of the shares of Common Stock present at the 2020 Annual Meeting, in person or by proxy, and entitled to vote on the proposal at the 2020 Annual Meeting. Abstentions will have the same effect as a vote against this proposal. You may vote for or against or you may abstain on this proposal. Your broker is not permitted to vote your shares of Common Stock on this proposal without receiving instructions from you. Broker non-votes would not be counted in determining the number of shares of Common Stock necessary for approval of this proposal and thus will not have a direct effect on the proposal. The opportunity to vote on this proposal is required pursuant to Section 14A of the Exchange Act. However, as an advisory vote, the vote on this proposal, if passed, would not be binding upon the Company and would serve only as a recommendation to the Board.

However, as an advisory vote, the vote on this proposal, if passed, would not be binding upon the Company and would serve only as a recommendation to the Board.

If other matters are properly brought before the 2020 Annual Meeting, the vote required will be determined in accordance with applicable law, the listing standards and rules of The Nasdaq Stock Market, LLC, and the Company’s Articles of Incorporation (as amended, the “Charter”) and By-Laws, as applicable.

What should I do in order to vote for the Nominees?

If your shares of Common Stock are held of record in your own name, please authorize a proxy to vote by marking, signing, dating and returning the enclosed GOLD proxy card in the postage-paid envelope provided or by instructing us by telephone or via the Internet as to how you would like your shares of Common Stock voted (instructions are on your GOLD proxy card).

If you hold your shares of Common Stock in “street name” with a bank, brokerage firm, dealer, trust company or other institution or nominee, only they can exercise your right to vote with respect to 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 institution or nominee to ensure that a GOLD proxy card is submitted on your behalf. Please follow the instructions to authorize a proxy to vote provided on the enclosed GOLD Voting Instruction Form. If your bank, brokerage firm, dealer, trust company or other nominee provides for voting instructions to be delivered to them by Internet or telephone, instructions will be included on the enclosed GOLD Voting Instruction Form.

YOUR VOTE IS VERY IMPORTANT. If you do not plan to attend the 2020 Annual Meeting, we encourage you to read this proxy statement and date, sign and return your completed GOLD proxy card prior to the 2020 Annual Meeting so that your shares of Common Stock will be represented and voted in accordance with your instructions. Even if you plan to attend the 2020 Annual Meeting in person, we recommend that you authorize a proxy to vote your shares of Common Stock in advance as described above so that your vote will be counted if you later decide not to attend the 2020 Annual Meeting.

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

Under the proxy rules, we may solicit proxies in support of our Nominees and also seek authority to vote for all of the Company’s nominees, other than those Company nominees we specify. This allows a Stockholder who desires to vote for up to a full complement of eight director nominees to use the GOLD proxy card to vote for our Nominees as well as the Company’s nominees for whom we are seeking authority to vote other than those nominees as to which the Stockholder does not seek authority to vote and will not exercise authority to vote. We have determined to nominate a slate of the three Nominees, Vann A. Avedisian, David J. Near and Todd W. Smith, and are seeking authority to vote for up to all of the Company’s nominees other than [                ], [                ] and [                ]. As a result, should a Stockholder so authorize us on the GOLD proxy card, we would cast votes for our three Nominees and for up to five of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote have agreed to serve with any of our Nominees, if elected.

How do I revoke a proxy?

You have the power to revoke a previously submitted proxy at any time before it is exercised even if you submitted a [COLOR] proxy card or form sent to you by the Company. If you are a registered holder of shares of Common Stock, you may revoke a previously submitted proxy by:

- 12 -

Please note, however, that only your last-dated proxy will count. Any proxy may be revoked at any time prior to its exercise at the 2020 Annual Meeting as described in this proxy statement. Attending the 2020 Annual Meeting alone without taking one of the actions set forth above will not revoke your proxy.

Stockholders who hold their shares of Common Stock in “street name” with a bank, brokerage firm, dealer, trust company or other institution or nominee will need to notify the person responsible for their account to revoke or withdraw previously given instructions. You may also provide your bank, broker or other nominee with new voting instructions. Only your latest dated instructions will count. Unless revoked in the manner set forth above and subject to the foregoing, duly authorized proxies in the form enclosed will be voted at the 2020 Annual Meeting in accordance with your instructions. We request that a copy of any revocation sent to the Company or any revocation notification sent to the person responsible for a bank or brokerage account also be sent to us, at c/o Morrow Sodali LLC, 470 West Avenue, Suite 3000, Stamford, Connecticut 06902, so that we may be aware of any revocation of a proxy.

PLEASE DO NOT RETURN ANY [COLOR] PROXY CARD YOU MAY RECEIVE FROM THE COMPANY OR OTHERWISE AUTHORIZE A PROXY TO VOTE YOUR SHARES OF COMMON STOCK AT THE 2020 ANNUAL MEETING, NOT EVEN AS A PROTEST VOTE. IF YOU HAVE ALREADY SENT [COLOR] A PROXY CARD TO THE COMPANY OR OTHERWISE AUTHORIZED A PROXY TO VOTE YOUR SHARES OF COMMON STOCK AT THE 2020 ANNUAL MEETING, IT IS NOT TOO LATE TO CHANGE YOUR VOTE. TO REVOKE YOUR PRIOR PROXY AND CHANGE YOUR VOTE, SIMPLY SIGN AND RETURN THE ENCLOSED GOLD PROXY CARD IN THE POSTAGE-PAID ENVELOPE PROVIDED. ONLY YOUR LATEST DATED PROXY WILL BE COUNTED.

Who is paying for the solicitation on behalf of the Investors?

The Investors will pay the entire expense of soliciting proxies for the 2020 Annual Meeting by the participants in this solicitation or on the participants’ behalf. The Investors do intend to seek reimbursement of such solicitation expenses from the Company.

Whom should I call if I have any questions about the solicitation?

If you have any questions, or need assistance in voting your shares of Common Stock, please call our proxy solicitor: Morrow Sodali LLC, toll free at (800) 662-5200, collect at (203-658-9400) or by email at VANN@morrowsodali.com.

YOUR VOTE IS IMPORTANT, NO MATTER HOW FEW SHARES YOU OWN. WE URGE YOU TO SIGN, DATE, AND RETURN THE ENCLOSED GOLD PROXY CARD TODAY TO VOTE “FOR” THE ELECTION OF OUR NOMINEES AND TO GRANT AUTHORITY TO VOTE FOR THE COMPANY’S NOMINEES OTHER THAN [                ], [                ] AND [                ].

Important Notice Regarding the Availability of Proxy Materials for the 2020 Annual Meeting:

The proxy materials are available at no charge at [www.                    .com.]

PROPOSAL NO. 1 – ELECTION OF NOMINEES

We propose that the Stockholders elect Vann A. Avedisian David J. Near and Todd W. Smith as directors of the Company at the 2020 Annual Meeting. According to publicly available information, the Board currently consists of eight directors, all of whom are up for election at the 2020 Annual Meeting. If our three Nominees are elected to the Board, then they will replace three of the Company’s incumbent directors.

The initial term of each Nominee, if elected, would be until the 2021 Annual Meeting or until their successors are duly elected and qualified in accordance with the By-Laws. Each Nominee has executed a consent to being named as a nominee in this proxy statement as such and to serving as a director of the Company, if so elected.

This proxy statement is soliciting proxies to elect Vann A. Avedisian, David J. Near and Todd W. Smith and to grant authority to vote for the Company’s nominees other than [                ], [                ] and [                ]. Therefore, should a Stockholder so authorize us, we will cast votes for our three Nominees and for up to five of the Company’s nominees. None of the Company’s nominees for whom we seek authority to vote has agreed to serve with any of our Nominees, if elected, and there is no assurance that they will do so.

The Company’s corporate governance guidelines, which are available on the Company’s website at http://investors.potbelly.com/static-files/bd2d60ee-0e31-4fee-b069-e033bb8cbc79 set forth guidelines to assist the Board in making a determination whether a director has a material relationship with the Company for purposes of determining independence. Based on the information furnished by the Nominees, we believe that each of the Nominees is independent and none of the Participants has any knowledge of any facts that would prevent the determination that each of the Nominees is independent.

In addition, each of the Nominees understands that, if elected as a director of the Company, each Nominee would have an obligation to act in the best interests of the Company and the Stockholders in accordance with their respective duties as a director.

We are not seeking control of the Board at the 2020 Annual Meeting. If elected, the Nominees would be a minority of the directors and would not alone be able to adopt resolutions or otherwise cause the Board to act. The Nominees intend to work actively with the other Board members to discuss the issues and challenges facing the Company and resolve them together. By utilizing their respective experience and working constructively with the other Board members, the Nominees believe they can effect positive change at the Company.

The Investors do not expect that the Nominees will be unable to stand for election. If any Nominee is unable to serve or for good cause will not serve, the Investors may seek to replace such Nominee with a substitute nominee to the extent substitution is permissible under applicable law and the Company’s organizational documents.

The Investors reserve the right to nominate additional persons, to the extent this is not prohibited under applicable law or the Company’s organizational documents, if the Company purports to increase the number of directorships, and/or the Company makes or announces any changes to the By-Laws or takes or announces any other action that purports to have, or if consummated would purport to have, the effect of disqualifying any of the Nominees or any additional nominee nominated pursuant to the foregoing, and/or any Nominee is unable to serve or for good cause will not serve. Additional nominations made pursuant to the foregoing are without prejudice to the position of the Investors that any attempt to change the size of the Board or disqualify any of the Nominees through By-Law amendments or otherwise would constitute unlawful manipulation of the Company’s corporate governance. The Investors reserves the right to challenge any action by the Company that has, or if consummated would have, the effect of disqualifying any Nominee. If the Investors are permitted to substitute a nominee or propose an additional nominee, the Investors will file and deliver supplemental proxy materials, including a revised GOLD proxy card, disclosing the information relating to any substitute nominee or additional nominee

- 14 -

that is required to be disclosed in solicitations for proxies for election of directors pursuant to Section 14 of the Exchange Act. Only in such case will the shares of Common Stock represented by the enclosed GOLD proxy card be voted for substitute nominees or additional nominees.

Information Regarding the Nominees

Information pertaining to the Nominees, including the name, age, present principal occupation, business address, and business experience for the past five years and certain other information, is set forth in the question and answer section of the proxy statement under the section entitled “Who are the Nominees?”, which we urge you to read. This information has been furnished to us by the Nominees. Other than as disclosed in this proxy statement, there is no arrangement or understanding between any of the Nominees and any other person(s) pursuant to which any such Nominee was or is to be selected as a director or nominee of the Company.

You should refer to the Company’s proxy statement for the 2020 Annual Meeting for the names, background, qualifications and other information concerning the Company’s nominees.

Arrangements between the Investors and the Nominees

Other than as set forth herein or in Annex A, no participant in this solicitation and no associate of any participant in this solicitation has any arrangements or understandings with any person or persons with respect to any future employment by the Company or its affiliates or with respect to any future transactions to which the Company or any of its affiliates will or may be a party.

Compensation of the Company’s Directors

If elected to the Board, the Nominees will not receive any compensation from the Investors to serve as Nominees for election or as a director, if elected, of the Company. They will, however, receive whatever compensation the Board has established for non-employee directors of the Company unless and until the Board determines to change such compensation. The following discussion summarizes the Company’s compensation and indemnification of directors based solely on the Company’s public filings.

According to the Company’s public filings, under its director compensation plan in effect for 2018, each non-employee director who was a member of the Board as of the 2018 Annual Meeting of Shareholders was eligible to receive $135,000 in annual compensation. Each non-employee director may elect between the following forms of payment for his or her annual compensation: (1) the non-employee director receives RSUs having a grant date fair market value of $135,000 (with a grant date on or before the end of the respective second fiscal quarter); or (2) the non-employee director receives: (a) $60,000 in cash (half of which will be paid on or before the end of the respective second fiscal quarter and half of which will be paid on or before the end of the respective fiscal year); plus (b) RSUs having a grant date fair market value of $75,000 (with a grant date on or before the end of the respective second fiscal quarter). Pursuant to the Company’s director compensation plan, the non-executive Chairman of the Board receives an additional $80,000 retainer, the Audit Committee Chair receives an additional $15,000 retainer, and the Compensation Committee Chair and the Nominating and Corporate Governance Chair each receives an additional $7,500 retainer. The non-executive Chairman of the Board, the Lead Director (if applicable), the Audit Committee Chair, the Compensation Committee Chair and the Nominating and Corporate Governance Committee Chair may each elect between the following forms of payment for such additional retainer: (1) RSUs having a grant date fair market value equal to such additional retainer amount (with a grant date on or before the end of the respective second fiscal quarter); or (2) cash in an amount equal to one-half such additional retainer amount (half of which will be paid on or before the end of the respective second fiscal quarter and half of which will be paid on or before the end of the respective fiscal year); plus RSUs having a grant date fair market value of half of such additional retainer amount (with a grant date on or before the end of the respective second fiscal quarter). RSUs shall vest as follows: fifty percent (50%) on the first anniversary of the grant date, and fifty percent (50%) on the second anniversary of the grant date.

- 15 -

We expect that the share ownership level of each current non-employee director will be set forth in the Company’s proxy statement for the 2020 Annual Meeting.

The Investors believe that the Company maintains, at its expense, a policy of insurance which insures its directors and officers. The By-Laws also contain a provision that provides for the indemnification of any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was or has agreed to become a director or officer of the Company against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her or on his or her behalf in connection with such action, suit or proceeding and any appeal therefrom, if he or she (x) acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company and, in the case of any such employee or agent, in a manner he or she reasonably believed to be not in violation of any policies or directives of the Company and (y) with respect to any criminal action or proceeding had no reasonable cause to believe his or her conduct was unlawful; except that in the case of an action or suit by or in the right of the Company to procure a judgment in its favor (i) such indemnification shall be limited to expenses (including attorneys’ fees) actually and reasonably incurred by such person in the defense or settlement of such action or suit and (ii) no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Company unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court shall deem proper. The Charter also contains a provision that provides for indemnification of officers and directors to the fullest extent permitted under the DGCL (and in particular Section 145 thereof), as from time to time amended. The Charter also contains a provision eliminating the personal liability of a director for monetary damages for breach of fiduciary duty as a director; except for liability (i) for breach of the director’s duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. The Investors expect that the Nominees, if elected, will be indemnified for service as directors of the Company to the same extent indemnification is provided to the current directors of the Company under the By-Laws and the Charter and be covered by the policy of insurance which insures the Company’s directors and officers.

None of the Nominees, or any of their respective associates, has received any cash compensation, cash bonuses, deferred compensation, compensation pursuant to plans, or other compensation, from, or in respect of, services rendered on behalf of the Company that is required to be disclosed under, or is subject to any arrangement described in Item 402 of Regulation S-K promulgated under the Exchange Act (“Regulation S-K”).

None of the Nominees has any position or office with the Company, and no occupation or employment with which the Nominees have been involved, during the past five years, was carried on with the Company or any corporation or organization that is a parent, subsidiary or other affiliate of the Company. Mr. Avedisian previously served on the Board from 2000 to 2015, including as Chairman of the Compensation and Organization Committee. Neither Mr. Smith nor Mr. Near has previously served on the Board.

Other than as disclosed herein, no participant is aware of any other arrangements pursuant to which any director of the Company was to be compensated for services during the Company’s last fiscal year.

Interests of the Nominees

The Nominees may be deemed to have an interest in their nominations for election to the Board by virtue of compensation the Nominees will receive from the Company as a director, if elected to the Board, and as described elsewhere in this proxy statement. The Investors expect that the Nominees, if elected, will be indemnified for service as directors of the Company to the same extent indemnification is provided to the current

- 16 -

directors of the Company under the By-Laws and the Charter and be covered by the policy of insurance which insures the Company’s directors and officers.

Other than as set forth in this proxy statement, none of the persons listed on Annex A of this proxy statement, including any Nominee, or any associate of the foregoing persons, has any substantial interest, direct or indirect, by security holdings or otherwise, in any matter to be acted upon at the 2020 Annual Meeting.

The information herein regarding a particular Nominee has been furnished to the Investors by such Nominee.

WE STRONGLY URGE YOU TO VOTE “FOR” THE ELECTION OF VANN A. AVEDISIAN, DAVID J. NEAR AND TODD W. SMITH AND TO GRANT AUTHORITY TO VOTE FOR THE COMPANY’S NOMINEES OTHER THAN [                ], [                ] AND [                ] BY MARKING, SIGNING, DATING AND RETURNING THE ENCLOSED GOLD PROXY CARD IN THE POSTAGE PAID ENVELOPE PROVIDED TO YOU WITH THIS PROXY STATEMENT. IF YOU HAVE SIGNED THE GOLD PROXY CARD AND NO MARKING IS MADE, YOU WILL BE DEEMED TO HAVE GIVEN A DIRECTION TO VOTE ALL THE SHARES OF COMMON STOCK REPRESENTED BY THE GOLD PROXY CARD “FOR” THE ELECTION OF VANN A. AVEDISIAN, DAVID J. NEAR AND TODD W. SMITH AND TO GRANT AUTHORITY TO VOTE FOR THE COMPANY’S NOMINEES OTHER THAN [                ], [                ] AND [                ].

Please do not return any [COLOR] proxy card you may receive from the Company or otherwise authorize a proxy (other than on the GOLD proxy card delivered by us to you) to vote your shares of Common Stock for the Company’s nominees. If you have already submitted a [COLOR] proxy card that may have been sent to you by the Company or otherwise authorized a proxy to vote your shares of Common Stock for the Company’s nominees, it is not too late to change your vote. To revoke your prior proxy and change your vote, simply sign and return the enclosed GOLD proxy card in the postage-paid envelope provided. Only your latest dated proxy will be counted.

PROPOSAL NO. 2 – RATIFICATION OF THE APPOINTMENT OF INDEPENDENT ACCOUNTANTS

- 20 -

OTHER PROPOSALS

Except as set forth in this proxy statement, we do not know of any other matters to be presented for approval by the Stockholders at the 2020 Annual Meeting. If, however, we learn of any other proposals made at a reasonable time before the 2020 Annual Meeting, we will either supplement this proxy statement and provide Stockholders with an opportunity to vote by proxy directly on such matters, or will not exercise discretionary authority with respect thereto. If other matters are properly presented thereafter, the persons named as proxies in the enclosed GOLD proxy card will vote the shares of Common Stock represented thereby in accordance with their discretion pursuant to the authority granted in the proxy.

NO APPRAISAL OR DISSENTER’S RIGHTS

Stockholders will not have rights of appraisal or similar dissenter’s rights with respect to any matters identified in this proxy statement to be acted upon at the 2020 Annual Meeting.

SOLICITATION OF PROXIES

The Nominees may make solicitations of proxies but, except as described herein, will not receive compensation for acting as Nominees.

Morrow Sodali LLC has been retained to provide solicitation and advisory services in connection with the 2020 Annual Meeting. Morrow Sodali LLC will receive a fee in an amount not to exceed [$                ] and reimbursement of reasonable and documented out-of-pocket expenses for its services to the Investors in connection with the solicitation. Approximately [    ] people may be employed by Morrow Sodali LLC to solicit proxies from the Stockholders for the 2020 Annual Meeting. The Investors have agreed to indemnify Morrow Sodali LLC in its capacity as solicitation agent against certain liabilities and expenses in connection with the solicitation.
