[SC 14D9/A] POTBELLY CORP Amended Tender Offer Recommendation

Rhea-AI Filing Summary

Potbelly Corporation filed voluntary supplemental disclosures to its previously submitted Schedule 14D-9 to address complaints and demand letters challenging a proposed transaction. The company states it believes the allegations are without merit but is providing extra detail to reduce the risk that litigation will delay or increase the cost of the Transactions. Management and its advisor included multi-year financial projections showing revenue rising from $487.1M (2025E) to $725.4M (2029E), and free cash flow forecasts that shift from a ($2.4M) figure to positive figures through the period. Valuation tables show the offer price context: a closing share price of $49.69, fully diluted equity of $1,660M and enterprise value of $2,410M with an implied EV/EBITDA of 12.2% for CY2025E and 11.0% for CY2026E. The filing includes a comparable transactions list with enterprise values and EV/LTM EBITDA multiples for industry precedent transactions.

Positive

• Voluntary supplemental disclosure to reduce litigation delay and defense expense
• Projected revenue growth from $487.1M to $725.4M (2025E–2029E)
• Free cash flow turns positive in the later projection years after early negative figure of ($2.4M)
• Valuation context provided showing implied EV/EBITDA ~12.2 for CY2025E

Negative

• Active complaints and demand letters allege disclosure issues that could trigger litigation
• Near-term non-cash charges and negative cash flow in certain periods (e.g., ($2.4M))
• Projections reliant on assumptions that, if missed, could weaken the presented valuation support

Insights

Corporate Counsel

TL;DR: Supplemental disclosures aim to neutralize litigation risk and preserve deal timing.

The company expressly states it regards the complaints and demand letters as without merit but has voluntarily provided additional disclosures to minimize the risk that such actions will delay the Transactions or increase defense costs. This is a common defensive measure to reduce the chance that plaintiffs can obtain injunctive relief based on alleged disclosure deficiencies.

Primary dependencies are whether plaintiffs introduce materially new allegations and whether courts view the supplements as adequate. Expect near-term effects tied to any filed suits and potential injunction motions; if no new material claims arise, the supplements are intended to narrow grounds for emergency relief.

Transaction Financial Analyst

TL;DR: Projections show revenue growth and improving cash generation supporting the deal valuation.

Management projections show revenue rising from $487.1M to $725.4M (2025E–2029E) with corresponding improvements in free cash flow from a ($2.4M) figure to positive cash generation in later years, which underpins the presented valuation metrics. The filing also provides an illustrative trading context with a closing share price of $49.69, equity of $1,660M, enterprise value $2,410M and implied EV/EBITDA near 12.2 for CY2025E.

Key risks include the accuracy of the projections and sensitivity to non-cash charges and working capital assumptions; comparables show a wide range of EV/EBITDA multiples, so pay attention to realized operating performance versus the stated projections over the next 12–24 months.

This Amendment No. 1 (this “Amendment No. 1”) amends and supplements the Solicitation/Recommendation Statement on Schedule 14D-9 (as further amended or supplemented from time to time, the “Schedule 14D-9”) previously filed by Potbelly Corporation, a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “SEC”) on September 23, 2025.

The Schedule 14D-9 relates to the tender offer by Hero Sub Inc., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of RaceTrac, Inc., a Georgia corporation (“Parent” or “RaceTrac”), to purchase, subject to certain conditions, any and all of the outstanding Shares at a price of $17.12 per Share, without interest (the “Offer Price”), net to the seller in cash, less any applicable withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated September 23, 2025 (as it may be amended or supplemented from time to time, the “Offer to Purchase”), and in the related Letter of Transmittal (as it may be amended or supplemented from time to time, the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer”). The Offer is described in the Tender Offer Statement on Schedule TO filed with the SEC on September 23, 2025, by Purchaser and Parent (together with any amendments and supplements thereto). The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of September 9, 2025 (the “Merger Agreement”), by and among the Company, Parent and Purchaser. The Merger Agreement provides, among other things, that following the consummation of the Offer and subject to the satisfaction or waiver of the applicable conditions set forth in the Merger Agreement, including the Minimum Condition, Purchaser will be merged with and into the Company, with the Company surviving as a wholly owned subsidiary of Parent.

Capitalized terms used but not otherwise defined in this Amendment No. 1 shall have the meanings ascribed to such terms in the Schedule 14D-9. The information in the Schedule 14D-9 is incorporated into this Amendment No. 1 by reference to all applicable items in the Schedule 14D-9, except that such information is hereby amended and supplemented to the extent specifically provided herein. Except as otherwise set forth in this Amendment, the information set forth in the Schedule 14D-9 remains unchanged and is incorporated herein by reference to the extent relevant to the items in this Amendment.

Explanatory Note:

As described further below, in connection with the Offer and the Merger Agreement, two complaints have been filed as individual actions by purported stockholders of the Company in the Supreme Court of the State of New York, County of New York, alleging, among other things, that the defendants (the Company and the Board) omitted and/or misrepresented certain material facts relating to the transaction contemplated by the Merger Agreement in the Schedule 14D-9 filed by the Company on September 23, 2025. Certain demand letters have also been sent to the Company by purported stockholders making similar allegations. The Company believes that the allegations in such complaints and demand letters are without merit. The Company believes that no supplemental disclosure is required under applicable laws and that the Schedule 14D-9, as originally filed on September 23, 2025, disclosed all material information required to be disclosed therein. However, to avoid the risk that lawsuits may delay or otherwise adversely affect the Transactions, and to minimize the expense of defending such actions, the Company wishes to make voluntarily certain supplemental disclosures related to the Transactions for the purposes of mooting the allegations in any complaints related to the Transactions, all of which are set forth below and should be read in conjunction with the Schedule 14D-9 in its entirety. Nothing in these supplemental disclosures shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein.

Item 3. Past Contacts, Transactions, Negotiations and Agreements.

Item 3 of the Schedule 14D-9 is hereby amended and supplemented as follows:

1. By adding the below paragraph after the first full paragraph under the section titled “Conflicts of Interest” on page 4 as follows:

Additionally, other than discussions or negotiations with respect to employment-related or compensation-related matters already disclosed in this Schedule 14D-9, prior to the execution of the Merger Agreement, there were no discussions or negotiations that occurred between Parent, Purchaser or their respective affiliates and any of the Company’s management, executive officers or directors with respect to post-closing employment, compensation or benefits.

Item 4. The Solicitation or Recommendation.

Item 4 of the Schedule 14D-9 is hereby amended and supplemented as follows:

1. By adding the bold text to the below paragraphs under the section titled “Background of the Offer and Merger” on page 12 as follows:

On March 14, 2025, Company management sent RaceTrac a draft confidentiality agreement (the “Transaction Confidentiality Agreement”). On March 18, 2025, the Company entered into the Transaction Confidentiality Agreement with RaceTrac, which contained customary nondisclosure and nonuse provisions, as well as a customary standstill provision containing standard fall-away rights that permitted RaceTrac to make acquisition proposals at any time after the Company entered into a definitive agreement with a third party providing for a change of control transaction of the Company. Following execution of the Transaction Confidentiality Agreement, on March 19, 2025, representatives of RaceTrac sent to Mr. Wright and Mr. Cirulis a priority due diligence request list in order to facilitate RaceTrac’s preparation of a proposal for a potential transaction with the Company.

2. By adding the bold text to the below paragraph under the section titled “Background of the Offer and Merger” on page 14 as follows:

On May 15, 2025, representatives of BofA sent representatives of Piper Sandler a preliminary, non-binding proposal to acquire all Shares for $13.50 per share in cash (the “May Offer”). The May Offer was subject to an eight-week exclusivity period, requested a six-week timeline for RaceTrac to complete its due diligence review of the Company and indicated that there would be no financing contingency in the definitive transaction agreement as the acquisition would be funded using cash on hand and existing debt facilities. The May Offer did not include reference to any post-closing arrangement, treatment of Company equity awards or other employment or retention matters with respect to the Company’s employees. Representatives of Piper Sandler promptly shared the May Offer with senior management of the Company, who subsequently shared the May Offer with the Board of Directors.

3. By adding the bold text to the below paragraph under the section titled “Background of the Offer and Merger” on page 15 as follows:

On July 17, 2025, representatives of BofA sent representatives of Piper Sandler a revised non-binding proposal to acquire all Shares for $16.35 per share in cash (the “July 17 Offer”). The July 17 Offer was subject to a six-week exclusivity period, requested a six-week timeline for RaceTrac to complete its due diligence review of the Company and reiterated that there would be no financing contingency in the definitive transaction agreement as the acquisition would be funded using cash on hand and existing debt facilities. The July 17 Offer did not include reference to any post-closing arrangement, treatment of Company equity awards or other employment or retention matters with respect to the Company’s employees. Representatives of Piper Sandler promptly shared the July 17 Offer with senior management of the Company, who subsequently shared the July 17 Offer with the Board of Directors.

4. By adding the bold text to the below paragraph under the section titled “Background of the Offer and Merger” on page 16 as follows:

On July 30, 2025, representatives of BofA sent representatives of Piper Sandler a revised non-binding proposal to acquire all Shares for $17.12 per share in cash (the “July 30 Offer”). BofA indicated that the July 30 Offer was RaceTrac’s “best and final” offer. The July 30 Offer was subject to a five-week exclusivity period, requested a five-week timeline for RaceTrac to complete its due diligence review of the Company, reiterated that there would be no financing contingency in the definitive transaction agreement, and included a requirement that the Company agree to include a non-solicitation provision, subject to a customary fiduciary exception, with a Company termination fee equal to 3.5% of the transaction’s equity value in the definitive agreement providing for a transaction. The July 30 Offer expressly rejected the Company’s request for expense reimbursement in the July Counterproposal. The July 30 Offer did not include reference to any post-closing arrangement, treatment of Company equity awards or other employment or retention matters with respect to the Company’s employees. Representatives of Piper Sandler promptly shared the July 30 Offer with senior management of the Company, who subsequently shared the July 30 Offer with the Board of Directors.

5. By adding the bold text to the below tables under the section titled “Certain Unaudited Prospective Financial Information” on page 27 as follows:

8. By adding the bold text and deleting the strikethrough text to the below paragraphs under the section titled “Discounted Cash Flow Analysis” on page 34 as follows:

Using a discounted cash flows analysis, Piper Sandler calculated an estimated range of theoretical values for the Company based on the net present value of (i) projected unlevered free cash flows from second half of fiscal 2025 (consisting of the third and fourth fiscal quarters of fiscal 2025) to fiscal year 2029, discounted back to June 29, 2025 (the end of the Company’s second fiscal quarter 2025), based on the Updated Projections furnished to Piper Sandler by the Company, and (ii) a terminal value at fiscal year 2029 based upon EBITDA exit multiples, discounted back to June 29, 2025. The unlevered free cash flows for each year were calculated from the Updated Projections as indicated in the table below: adjusted EBITDA less dark rent expense and shop closure costs, less income taxes, add non-cash rent, less net capital expenditures and less the change in net working capital.

9. By adding the bold text and deleting the strikethrough text to the below paragraphs under the section titled “Information About Piper Sandler” on page 38 as follows:

Piper Sandler acted as a financial advisor to the Company in connection with the Merger and will receive a fee, currently estimated to be approximately $6.9 million from the Company. A significant portion of Piper Sandler’s fee (approximately $5.9 million) is contingent upon consummation of the Merger, and $1.0 million of such fee has been earned by Piper Sandler for rendering its fairness opinion and an additional $50,000 was earned by Piper Sandler in the form of a non-refundable retainer fee, both of such amounts have been paid by the Company to Piper Sandler and is are creditable against the total fee. The opinion fee was not contingent upon the consummation of the Merger or the conclusions reached in Piper Sandler’s opinion. The Company has also agreed to indemnify Piper Sandler against certain liabilities and reimburse Piper Sandler for certain expenses in connection with its services. Other than as described above, within the past three years, Piper Sandler has not performed any investment banking services or received investment banking fees from the Company, RaceTrac or Purchaser. Piper Sandler is currently engaged as financial advisor for the Company and the Board of Directors in connection with the Company’s review of strategic alternatives. In addition, in the ordinary course of its business, Piper Sandler and its affiliates may actively trade securities of the Company for its own account or the account of its customers and, accordingly, may at any time hold a long or short position in such securities. Piper Sandler may also, in the future, provide investment banking and financial advisory services to the Company or the Parent or entities that are affiliated with the Company or the Parent, for which Piper Sandler would expect to receive compensation.

Item 8. Additional Information.

Item 8 of the Schedule 14D-9 is hereby amended and supplemented as follows:

1. By deleting the sentence under the section titled “Legal Proceedings” on page 45 and replacing it with the following paragraphs:

In connection with the Offer and Merger Agreement, two complaints have been filed as individual actions in the Supreme Court of the State of New York, County of New York and are captioned Eric Miller v. Potbelly Corporation, et. al., Index No. 655857/2025 (filed October 1, 2025) (the “Miller Complaint”) and Thomas Lewis vs. Potbelly Corporation, et. al., Index 655886/2025 (filed October 2, 2025) (the “Lewis Complaint” and, together with the Miller Complaint, the “Complaints”). The Complaints allege, among other things, that the defendants (the Company and the Board) omitted and/or misrepresented certain material facts relating to the transaction contemplated by the Merger Agreement from the Schedule 14D-9 filed by the Company on September 23, 2025. The Complaints seek, among other relief, (i) injunctive relief preventing the consummation of the Merger, (ii) recission of the Merger Agreement or punitive damages and (iii) an award of plaintiff’s fees and expenses of the action, including reasonable attorneys’ and expert fees and expenses. Certain demand letters have also been sent to the Company by purported stockholders making similar allegations.

The outcome of the matters described above cannot be predicted with certainty. However, the Company believes that the allegations in the Complaints lack merit. Additional complaints or demand letters may be filed against or received by the Company, the Board, Parent and/or Purchaser in connection with the Transactions, the Schedule TO and the Schedule 14D-9. If additional similar complaints are filed or demand letters received, absent new or different allegations that are material, the Company, Purchaser or Parent will not necessarily announce such additional complaints or demand letters.

2. By deleting the second and third paragraphs under the section titled “Antitrust Compliance” on page 46 in their entirety and replacing them with the following paragraph:

Each of the Company and Parent filed a Notification and Report Form under the HSR Act with respect to the Transactions with the Antitrust Division and the FTC on September 26, 2025. The waiting period under the HSR Act will expire on October 14, 2025, at 11:59 p.m., New York City time and the Company and RaceTrac have requested “early termination” of such waiting period. This period may be shortened if the reviewing agency grants “early termination” of the waiting period, or lengthened if Parent voluntarily withdraws and refiles to allow a second 15-day waiting period, or if the reviewing agency issues to Parent a formal request for additional information and documentary material, in which case the waiting period expires ten days after the date when Parent has certified its substantial compliance with such request. The Antitrust Division and the FTC assess the legality under the antitrust laws of transactions such as the acquisition of Shares by Purchaser pursuant to the Offer. At any time before or after the consummation of any such transactions, the Antitrust Division or the FTC could take such action under the antitrust laws of the United States as it deems necessary or desirable in the public interest, including seeking to enjoin the purchase of Shares pursuant to the Offer or seeking divestiture of Shares so acquired or divestiture of substantial assets of the Company and/or RaceTrac. Private parties (as well as individual states of the United States) may also bring legal actions under the antitrust laws of the United States or state antitrust laws. There can be no assurance that a challenge to the Offer and the Merger on antitrust grounds will not be made or, if such a challenge is made, the result thereof.
