On December 16, 2025, a case captioned Mark Thomas v. Denny’s Corporation, et al., Index No. 656541/2025, was filed in the Supreme Court of the State of New York, County of New York Court (the “Thomas Lawsuit”). On December 17, 2025, a case captioned James Walsh v. Denny’s Corporation, et al., Index No. 656542/2025, was filed in the Supreme Court of the State of New York, County of New York Court (the “Walsh Lawsuit”, and together with the “Thomas Lawsuit”, the “Lawsuits”). The complaints in the Lawsuits allege, in essence, that the Proxy Statement as filed with the SEC was false and misleading in violation of the defendants’ obligation to disclose all material information relevant to stockholders and necessary to permit an informed decision on whether to vote in favor of the Merger. The Lawsuits allege that the Company omitted and/or misrepresented material information concerning, among other things: (i) the financial projections for the Company prepared by management of the Company; (ii) the data and inputs underlying the financial valuation analyses that support the fairness opinion provided by the Company’s financial advisor, Truist Securities, Inc. (“Truist Securities”); (iii) potential conflicts of interest faced by Company insiders; and (iv) the background of the Merger. The Lawsuits name as defendants the Company and its directors and seek, among other forms of requested relief, an order enjoining the consummation of the Merger. There can be no assurance regarding the ultimate outcome of the Lawsuits.

The supplemental disclosures should be read in conjunction with the Proxy Statement, which is available on the Company’s website at the Investor Relations section of https://investor.dennys.com/overview/default.aspx or at the SEC’s website at www.sec.gov. The Proxy Statement, along with periodic reports and other information the Company files with the SEC, should be read in its entirety, including the cautionary notes regarding the risks and limitations associated with relying on prospective financial information. To the extent information set forth herein differs from or updates information contained in the Proxy Statement, the information set forth herein shall supersede or supplement the information in the Proxy Statement. Defined terms used but not defined herein have the meanings set forth in the Proxy Statement. All page references in the information below are to pages in the Proxy Statement. Paragraph references used herein refer to the Proxy Statement before any additions or deletions resulting from the supplemental disclosures.

The disclosure in the Proxy Statement in the section “The Merger—Background of the Merger” beginning on page 25 is hereby supplemented by adding the bolded and underlined disclosure to the last paragraph beginning on page 25 of the Proxy Statement as follows:

Later on July 18, 2024, following the meeting, the Company received an unsolicited non-binding indication of interest from Yadav Enterprises and TriArtisan Capital Advisors LLC (in this Background section, “TriArtisan”), a private equity firm with, at the time, several existing restaurant holdings, including PF Chang’s, TGI Friday’s and Hooters (the “July 18, 2024 IOI”), that contemplated those entities acquiring the Company for approximately $470 million, or $9.00 per share, subject to completion of due diligence and the negotiation of a definitive agreement. The July 18, 2024 IOI stated that the proposed acquisition would be on a cash-free, debt-free basis, free and clear of all liens and encumbrances, and assumed that the Company would be delivered with sufficient working capital to operate the business in the normal course. It stated further that the proposed acquisition would be funded with cash on hand from Yadav Enterprises, TriArtisan’s sources of equity capital, senior secured debt financing, including the Company’s current assumable debt, as well as with financing to be obtained from other sources. The July 18, 2024 IOI stated that the buyers intended to partner with management and anticipated that they would aim to retain substantially all of the employees of the Company, but contained no mention of specific individuals expected to remain with the Company, or the terms of any post-closing employment arrangements. It also included no mention of equity participation by management in the transaction.

The disclosure in the Proxy Statement in the section “The Merger—Background of the Merger” beginning on page 25 is hereby supplemented by adding the bolded and underlined disclosure to the sixth full paragraph on page 26 of the Proxy Statement as follows:

On August 23, 2024, the Company received a revised unsolicited non-binding indication of interest from TriArtisan (the “August 23, 2024 IOI”). Yadav Enterprises was not a party to this indication of interest. The August 23, 2024 IOI contemplated TriArtisan acquiring the Company for a reduced price of approximately $420 million, or $8.25 per share, while otherwise substantially repeating the elements of the July 18, 2024 IOI, other than stating that the proposed acquisition would be funded with cash on hand from TriArtisan’s sources of equity capital, senior secured debt financing, including the Company’s current assumable debt, as well as with financing to be obtained from other sources. The August 23, 2024 IOI stated that the buyers intended to partner with management and anticipated that they would aim to retain substantially all of the employees of the Company, but contained no mention of specific individuals expected to remain with the Company, or the terms of any post-closing employment arrangements. It also included no mention of equity participation by management in the transaction.

The disclosure in the Proxy Statement in the section “The Merger—Background of the Merger” beginning on page 25 is hereby supplemented by adding the bolded and underlined disclosure to and deleting the struck-through disclosure from the sixth full paragraph on page 27 of the Proxy Statement as follows:

Beginning in mid-September 2024, at the Company’s request, Truist Securities contacted 26 private equity firms that were identified by Truist Securities to the Company as being the most likely potential candidates for a strategic transaction with the Company. In identifying these parties, consideration was given to various factors, including the parties’ financial resources and their experience with companies in the restaurant space. These parties were provided with a basic overview of the Company and informed that if they entered into a non-disclosure agreement they would receive packages containing non-public financial and operating information regarding the Company. A total of ten parties entered into non-disclosure agreements with the Company, each of which contained a standstill provision that included a “don’t ask, don’t waive” provision prohibiting the other party to such agreement from requesting a waiver of the standstill other than by making a confidential request to the Board, and were thereafter provided with a confidential information presentation regarding the Company.

On April 1, 2025, Mr. Yadav contacted Ms. Valade and sent her a new unsolicited indication of interest from TriArtisan, dated April 2, 2025 (the “April 2, 2025 IOI”) that contemplated TriArtisan acquiring the Company for approximately $310 million, or $6.00 per share. The April 2, 2025 IOI stated that the proposed acquisition would be on a cash-free, debt-free basis, free and clear of all liens and encumbrances, and assumed that the Company would be delivered with sufficient working capital to operate the business in the normal course. It stated further that the proposed acquisition would be funded with TriArtisan’s sources of equity capital, debt financing, including the Company’s current assumable debt, as well as with financing to be obtained from other sources. The April 2, 2025 IOI stated that the buyers intended to partner with management and anticipated that they would aim to retain substantially all of the employees of the Company, but contained no mention of specific individuals expected to remain with the Company, or the terms of any post-closing employment arrangements. It also included no mention of equity participation by management in the transaction.

The disclosure in the Proxy Statement in the section “The Merger—Background of the Merger” beginning on page 25 is hereby supplemented by adding the bolded and underlined disclosure to and deleting the struck-through disclosure from the third full paragraph on page 29 of the Proxy Statement as follows:

During April 2025, as it had described to the Board at the April 9, 2025 meeting, representatives of Truist Securities contacted 28 other third parties, including the ten parties contacted in the Fall 2024 process who had executed NDAs. Of these parties, 19 entered into non-disclosure agreements containing certain customary non-solicit and standstill provisions that included “don’t ask, don’t waive” provisions prohibiting the other party to such agreement from requesting a waiver of the standstill other than by making a confidential request to the Board.

The disclosure in the Proxy Statement in the section “The Merger—Background of the Merger” beginning on page 25 is hereby supplemented by adding the bolded and underlined disclosure to the third full paragraph on page 30 of the Proxy Statement as follows:

TriArtisan’s June 4, 2025 IOI continued to propose a purchase price of $6.00 per share, on substantially the same basis and subject to the same conditions as set forth in its April 2, 2025 IOI. Party C’s indication of interest proposed a price per share in a range from $4.65 to $5.45 to acquire the Company on a cash-free and debt-free basis, subject to confirmatory business, accounting, tax, benefits, insurance, environmental and legal due diligence, and subject to Party C obtaining market-based financing. The June 4, 2025 IOI stated that the buyers intended to work in partnership with management but contained no other mention of any post-closing employment matters. It also included no mention of equity participation by management in the transaction.

The disclosure in the Proxy Statement in the section “The Merger—Background of the Merger” beginning on page 25 is hereby supplemented by adding the bolded and underlined disclosure to the seventh full paragraph on page 30 of the Proxy Statement as follows:

On June 30, 2025, Truist Securities received and forwarded to the Company a revised non-binding indication of interest from TriArtisan (the “June 30, 2025 IOI”). The June 30, 2025 IOI proposed an increased purchase price of $6.25 per share, on substantially the same basis and subject to the same conditions as set forth in its June 12, 2025 IOI, and described the following committed financing arrangements to which it was subject: (i) $200 million in sale/leaseback financing on all Company-owned real estate properties; (ii) $225 million in debt financing, to be provided either by the Company’s existing lenders or third-party debt sources, subject to customary terms; and (iii) $200 million in equity financing from TriArtisan-affiliated equity sources. TriArtisan did not include with its offer, as it had been requested to do, support letters from its equity financing sources. The June 30, 2025 IOI stated that the buyers intended to work in partnership with management but contained no other mention of any post-closing employment matters. It also included no mention of equity participation by management in the transaction.

Truist Securities performed a discounted cash flow analysis of the Company by calculating the estimated net present value of the projected unlevered, after-tax free cash flows of the Company based on the Denny’s Projections. Truist Securities, taking into account its experience and professional judgment, applied a range of perpetuity growth rates of 2.0% to 3.0% and discount rates ranging from 11.5% to 12.5% (which Truist derived based on its estimate of the Company’s weighted average cost of capital using its experience and professional judgment). Truist also calculated a range of terminal values for the Company, from $577.9 million to $671.2 million, as of December 31, 2029 (the end of the period addressed in the Denny’s Projections) by applying such ranges of perpetuity growth rates and discount rates to projected unlevered free cash flows for the Company. The discounted cash flow analysis indicated an implied value reference range of $5.13 to $7.11 per Company Share, as compared to the Merger Consideration of $6.25 per Company Share in the Merger pursuant to the Merger Agreement.

The disclosure in the Proxy Statement in the section “The Merger—Opinion of Truist Securities” beginning on page 44 is hereby supplemented by adding the bolded and underlined disclosure to and deleting the struck-through disclosure from the first full paragraph on page 49 of the Proxy Statement as follows:

Forward-looking statements often contain words such as “may,” “can,” “could,” “would,” “should,” “expects,” “anticipates,” “estimates,” “intends,” “plans,” “believes,” “seeks,” “will,” “is likely to,” “scheduled,” “positioned to,” “continue,” “forecast,” “aim,” “goal,” “target,” “predicting,” “projection,” “potential” or similar expressions, although not all forward-looking statements contain these words. Forward-looking statements may include references to goals, plans, strategies, objectives, projected costs or savings, anticipated future performance, results, events or transactions of the Company and the expected timing of the proposed transaction and other statements that are not strictly historical in nature. These forward-looking statements are based on management’s current expectations, forecasts and assumptions and could ultimately prove inaccurate. This means the forward-looking statements involve a number of risks and uncertainties that could cause actual results to differ materially from those expressed or implied in the forward-looking statements, including, but not limited to: uncertainties as to the timing of the proposed transaction; uncertainties as to how many of the Company’s stockholders will vote in favor of the proposed transaction including the possibility that the Company’s stockholders may not approve the proposed transaction; the possibility that competing offers will be made; the ability to receive the required consents and regulatory approvals for the proposed transaction and to satisfy the other conditions to the closing of the transaction on a timely basis or at all; the risk that, prior to the completion of the transaction, the Company’s business and its relationships with employees, collaborators, vendors and other business partners could experience significant disruption due to transaction-related uncertainty; the risk that stockholder litigation in connection with the transaction may result in significant costs of defense, indemnification and liability; negative effects of the announcement of the transaction on the market price of Company Shares and/or on the Company’s business, financial condition, results of operations and financial performance; and the ability of the Company to retain and hire key personnel; and the risks and uncertainties pertaining to the Company’s business, including those detailed under “Risk Factors” and elsewhere in the Company’s public periodic filings with the SEC. There can be no assurance that the proposed transaction or any other transaction described above will in fact be consummated in the manner described or at all. Stockholders, potential investors and other readers are urged to consider these risks and uncertainties in evaluating forward-looking statements and are cautioned not to place undue reliance on the forward-looking statements. It is not possible to anticipate or foresee all risks and uncertainties, and investors should not consider any list of risks and uncertainties to be exhaustive or complete. For additional information on identifying factors that may cause actual results to vary materially from those stated in forward-looking statements, please see the Company’s statements and reports on Forms 10-K, 10-Q and 8-K filed with or furnished to the SEC and other written statements made by the Company from time to time.
