Item 1.01.

Entry into a Material Definitive Agreement.

On September 10, 2025, Potbelly Corporation, a Delaware corporation (the “Company”), announced the execution of an Agreement and Plan of Merger (the “Merger Agreement”) with RaceTrac, Inc., a Georgia corporation (“Parent”), and Hero Sub Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”).

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Merger Sub has agreed to commence a tender offer (the “Offer”), to purchase all of the shares of common stock, par value $0.01 per share (the “Company Common Stock”), of the Company issued and outstanding (the “Shares”) at a price of $17.12 per Share (the “Merger Consideration”), in cash, without interest thereon (but subject to applicable withholding).

The Offer will initially remain open for a minimum of 21 business days from the date of commencement of the Offer. If at the scheduled expiration time of the Offer any condition to the Offer has not been satisfied and has not been waived by Parent or Merger Sub (to the extent permitted by the Merger Agreement), Merger Sub will, and Parent will cause Merger Sub to, extend the Offer in accordance with the terms of the Merger Agreement to permit the satisfaction of all Offer conditions. The obligation of Merger Sub to consummate the Offer is subject to the satisfaction or waiver of customary conditions, including, among others, (i) there being validly tendered and not validly withdrawn prior to the expiration of the Offer a number of Shares that, considered together with all other Shares (if any) beneficially owned by Parent and its affiliates, represent at least one more Share than 50% of the total number of Shares outstanding at the time of the expiration of the Offer (the “Minimum Condition”), (ii) since the date of the Merger Agreement, there shall not have occurred and be continuing any Company Material Adverse Effect (as defined in the Merger Agreement), (iii) the waiting period applicable to the Offer under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, having expired or otherwise been terminated, (iv) the absence of any law or order by any governmental authority of competent jurisdiction prohibiting, restricting, enjoining or otherwise making illegal the consummation of the Offer or the Merger, (v) the Merger Agreement not having been terminated in accordance with its terms (the “Termination Condition”) and (vi) other customary conditions set forth in Annex I to the Merger Agreement. The Minimum Condition and the Termination Condition may not be waived by Parent or Merger Sub without the prior written consent of the Company.

Following the consummation of the Offer, subject to the terms and conditions of the Merger Agreement and in accordance with Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent in accordance with the DGCL. At the effective time of the Merger (the “Effective Time”), each Share that is not validly tendered and irrevocably accepted for purchase pursuant to the Offer, other than any share (i) held by a holder who is entitled to demand appraisal and who has (or for which the “beneficial owner” (as defined in Section 262(a) of the DGCL) has) properly exercised appraisal rights with respect thereto in accordance with, and who has (and, to the extent applicable, for which the applicable beneficial owner has) complied with, Section 262 of the DGCL with respect to any such shares of Company Common Stock held by such holder or (ii) held by the Company as treasury stock or owned by Parent, Merger Sub or any of Parent’s other subsidiaries (including shares of Company Common Stock acquired pursuant to the Offer), will thereupon be converted into the right to receive cash in an amount equal to the Merger Consideration, on the terms and subject to the conditions set forth in the Merger Agreement.

Pursuant to the terms of Section 2.7(a) of the Merger Agreement, at the Effective Time, (A) each of the Company’s restricted stock units (the “Company RSUs”) that is outstanding and vested (but not yet settled) as of immediately prior to the Effective Time, taking into account any acceleration of vesting of any Company RSU that occurs upon the Effective Time (each, a “Vested Company RSU”), will automatically, without any action on the part of Parent, Merger Sub, the Company or the holder thereof, be cancelled and converted into and will become the right to receive an amount in cash, without interest thereon (but subject to applicable withholding), equal to the product obtained by multiplying (i) the Merger Consideration (as defined in the Merger Agreement) by (ii) the total number of shares of Company Common Stock subject to such Company RSU and (B) each outstanding Company RSU that is not a Vested Company RSU (each, an “Unvested Company RSU”) will, automatically and without any required action on the part of the holder thereof, be cancelled and substituted into the contingent right to receive from Parent or the Surviving Corporation an aggregate amount (without interest) in cash (a “Substituted RSU Cash Award”) equal to the product obtained by multiplying (1) the Merger Consideration by (2) the total number of shares of Company Common Stock subject to such Unvested Company RSU. Each such Substituted RSU Cash Award will continue to

have, and will be subject to, the same vesting terms and conditions as applied to the corresponding Unvested Company RSU immediately prior to the Effective Time, except that each such Substituted RSU Cash Award will be afforded “double-trigger” accelerated vesting upon the applicable holder’s termination without cause or resignation for good reason, in each case, that occurs within 24 months following the consummation of the transactions contemplated by the Merger Agreement.

Pursuant to the terms of Section 2.7(b) of the Merger Agreement, at the Effective Time, each of the Company’s performance-based restricted stock units (the “Company PSUs”) that is outstanding and unvested as of immediately prior to the Effective Time, will automatically, without any action on the part of Parent, Merger Sub, the Company or the holder thereof, be cancelled and substituted into and will become the contingent right to receive an amount in cash, without interest thereon (but subject to applicable withholding) (a “Substituted PSU Cash Award”), equal to the product obtained by multiplying (i) the Merger Consideration by (ii) the total number of shares of Company Common Stock subject to such Company PSU, with the achievement of the performance-based vesting metrics applicable to each Company PSU based on the greater of target or actual achievement of the applicable performance metrics, as determined by the Compensation Committee of the board of directors of the Company (the “Company Board”) as of the day prior to the Closing Date. Each such Substituted PSU Cash Award will be payable on the last day of the performance period that applied to the corresponding Company PSUs immediately prior to the Effective Time (such date, the “Vesting Date”), subject to the applicable holder’s continued employment or service through the Vesting Date, except that each such Substituted PSU Cash Award will be afforded “double-trigger” accelerated vesting upon such applicable holder’s termination without cause or resignation for good reason, in each case, that occurs within 24 months following the consummation of the transactions contemplated by the Merger Agreement.

Pursuant to the terms of Section 2.7(c) of the Merger Agreement, each of the Company’s outstanding options to purchase shares of Company Common Stock (the “Company Options”) that is outstanding, whether vested or unvested as of immediately prior to the Effective Time will automatically, without any action on the part of Parent, Merger Sub, the Company or the holder thereof, be cancelled and converted into and will become the right to receive an amount in cash, without interest thereon (but subject to applicable withholding), equal to the product obtained by multiplying (i) the total number of shares of Company Common Stock subject to such Company Option by (ii) the excess, if any, of the Merger Consideration over the exercise price of such Company Option, less applicable taxes required to be withheld with respect to such payment.

Pursuant to the terms of Section 2.8 of the Merger Agreement, at the Effective Time, (a) each of the Company’s outstanding warrants to purchase shares of Company Common Stock (the “Company Warrants”) outstanding and unexercised as of immediately prior to the Effective Time, will automatically, without any action on the part of Parent, Merger Sub, the Company or the holder thereof, be cancelled and converted into and will become the right to receive an amount in cash, without interest thereon (but subject to applicable withholding), equal to the product obtained by multiplying (i) the total number of shares of Company Common Stock underlying such Company Warrant by (ii) the excess, if any, of the Merger Consideration over the exercise price of such Company Warrant, less applicable Taxes required to be withheld with respect to such payment (the “Warrant Consideration”), and (b) the holder of such Company Warrant, in lieu of shares of Company Common Stock immediately purchasable and receivable upon the exercise of such Company Warrant, will be entitled only to receive the Warrant Consideration in respect of such Company Warrant and will have no other rights pursuant to such holder’s ownership of such Company Warrant.

The Merger Agreement includes representations, warranties and covenants of the Company, Parent and Merger Sub customary for a transaction of this nature. The Company has also agreed (i) to use commercially reasonable efforts to conduct its business in all material respects in the ordinary course of business consistent with past practice, and (ii) not to take certain actions prior to the earlier to occur of (x) the termination of the Merger Agreement and (y) the Effective Time.

The Company has agreed to customary “no-shop” restrictions on its ability to solicit alternative acquisition proposals from third parties and engage in discussions or negotiations with third parties regarding alternative acquisition proposals. Notwithstanding these restrictions, the Company may, under certain circumstances, provide information to and participate in discussions or negotiations with third parties with respect to a bona fide written alternative acquisition proposal that the Company Board has determined in good faith (after consultation with its

financial advisors and outside legal counsel) constitutes or could reasonably be expected to result in a Superior Proposal (as defined in the Merger Agreement), if failing to do so would be reasonably likely to be inconsistent with the Company Board’s fiduciary duties under applicable law.

The Merger Agreement also includes customary termination provisions for both the Company and Parent, and provides that, in connection with the termination of the Merger Agreement under specified circumstances, including termination by the Company to accept and enter into an agreement with respect to a Superior Proposal, the Company will pay Parent a termination fee of $19,800,000. The parties to the Merger Agreement are also entitled to specifically enforce the terms and provisions of the Merger Agreement.

The Company Board has unanimously (i) determined and declared that the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger, are advisable to and in the best interests of the Company and its stockholders, (ii) approved the execution, delivery and performance by the Company of the Merger Agreement and the consummation of the transactions contemplated thereby, including the Offer and the Merger, (iii) resolved to recommend that the Company’s stockholders accept the Offer and tender their shares to Merger Sub pursuant to the Offer and (iv) agreed and authorized that the Merger be governed by Section 251(h) of the DGCL.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and which is incorporated herein by reference. The Merger Agreement has been filed to provide information to investors regarding its terms. The Merger Agreement is not intended to provide any other factual information about the Company, Parent or Merger Sub, their respective businesses, or the actual conduct of their respective businesses during the period prior to the consummation of the Offer, the Merger or the other transactions contemplated therein. The Merger Agreement and this summary should not be relied upon as disclosure about the Company or Parent. None of the Company’s stockholders or any other third parties should rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or conditions of the Company, Parent, Merger Sub or any of their respective subsidiaries or affiliates. The Merger Agreement contains representations and warranties that are the product of negotiations among the parties thereto and that the parties made to, and solely for the benefit of, each other as of specified dates. The assertions embodied in those representations and warranties are subject to qualifications and limitations agreed to by the respective parties and are also qualified in important part by confidential disclosure schedules delivered by the Company to Parent and Merger Sub in connection with the Merger Agreement. The representations and warranties may have been made for the purpose of allocating contractual risk among the parties to the Merger Agreement instead of establishing these matters as facts and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to stockholders or investors. Accordingly, investors should consider the information in the Merger Agreement in conjunction with the entirety of the factual disclosure about the Company in the Company’s public reports filed with the Securities and Exchange Commission (the “SEC”). Information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

Tender and Support Agreement

As of the date of the Merger Agreement, the Shares subject to the Tender and Support Agreement comprised approximately 10.2% of the outstanding Shares.

Certain statements either contained in or incorporated by reference into this document, other than purely historical information, including statements relating to the acquisition of the Company by Parent and any statements relating to the Company’s business and expected operating results, and the assumptions upon which those statements are based, are “forward-looking statements.” These forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and include words such as “believes,”

“plans,” “anticipates,” “projects,” “estimates,” “expects,” “intends,” “strategy,” “future,” “opportunity,” “may,” “will,” “should,” “could,” “potential,” or similar expressions.
