8-K: Denny's Merger Faces Shareholder Lawsuits, Proxy Supplemented

Denny's Corporation files a supplement to its merger proxy statement to address shareholder lawsuits and demand letters alleging inadequate disclosures regarding the proposed acquisition by TriArtisan Capital Advisors LLC.

Summary

• Denny's Corporation (the Company) is subject to a merger agreement with Sparkle Topco Corp. and Sparkle Acquisition Corp., entities controlled by funds managed by affiliates of TriArtisan Capital Advisors LLC, entered into on November 3, 2025.
• Upon completion of the merger, Denny's will become a wholly owned subsidiary of Buyer and will cease to be publicly traded.
• Two lawsuits, Mark Thomas v. Dennys Corporation, et al. and James Walsh v. Dennys Corporation, et al., were filed on December 16 and 17, 2025, respectively, in New York, alleging the Definitive Proxy Statement was false and misleading.
• The lawsuits claim omissions and misrepresentations regarding financial projections, data supporting the fairness opinion by Truist Securities, potential conflicts of interest for Company insiders, and the background of the Merger.
• The lawsuits seek, among other forms of relief, an order enjoining the consummation of the Merger.
• Multiple purported stockholders have also delivered demand letters alleging disclosure deficiencies in the Proxy Statement and threatening lawsuits if not addressed.
• The Company believes the claims are without merit but is voluntarily supplementing the Proxy Statement to moot the unmeritorious disclosure claims, alleviate litigation costs, risks, and uncertainties, and provide additional information to stockholders.
• Supplemental disclosures include details of prior unsolicited non-binding indications of interest from Yadav Enterprises and TriArtisan, which ranged from $9.00 per share (July 2024) to $6.00 per share (April 2025), before the final $6.25 per share offer.
• These prior indications of interest did not mention specific post-closing employment arrangements or equity participation by management.
• Truist Securities contacted 26 private equity firms in Fall 2024 and 28 other third parties in April 2025 regarding a potential strategic transaction.
• The discounted cash flow analysis performed by Truist Securities indicated an implied value reference range of $5.13 to $7.11 per Company Share, compared to the Merger Consideration of $6.25 per Company Share.
• Truist Securities received approximately $2.6 million in compensation from Denny's for serving as joint lead arranger and joint bookrunner on the Company's revolving credit facility during the prior two years.
• Estimated financial results for full-year 2025 were updated in August 2025 based on Q2 2025 performance, resulting in downward adjustments for EBIT (from $45.0M to $40.8M), Net Income (from $18.8M to $14.4M), Adjusted EBITDA (from $83.0M to $79.9M), and Unlevered Free Cash Flow for the remaining 2025 (from $45.5M to $24.4M).

Sentiment

Score: 4

Explanation: The filing indicates significant negative sentiment due to ongoing shareholder litigation challenging the merger's disclosures and seeking to enjoin the transaction. Additionally, the downward revision of 2025 financial projections and the fact that the final offer price is substantially lower than initial indications contribute to a cautious outlook, despite the company's efforts to supplement disclosures.

Positives

• The Company is proactively supplementing its proxy statement to address shareholder concerns and litigation, aiming to reduce legal costs and uncertainties.
• The merger consideration of $6.25 per share falls within the implied value reference range of $5.13 to $7.11 per share derived from Truist Securities' discounted cash flow analysis.

Negatives

• Shareholder lawsuits and demand letters allege material omissions and misrepresentations in the original proxy statement, creating legal and reputational risks.
• The lawsuits seek to enjoin the merger, introducing uncertainty regarding its timely completion or even its consummation.
• Estimated financial projections for 2025 were revised downwards in August 2025, including EBIT, Net Income, Adjusted EBITDA, and Unlevered Free Cash Flow, indicating a weaker short-term outlook.
• The final merger offer of $6.25 per share is significantly lower than initial unsolicited indications of interest, which were as high as $9.00 per share.

Risks

• Uncertainties regarding the timing of the proposed transaction.
• 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 other closing conditions 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.
• The ability of the Company to retain and hire key personnel.
• General business risks detailed in the Company's public periodic filings with the SEC.

Future Outlook

The proposed transaction's completion is subject to various uncertainties, including stockholder approval, regulatory consents, and the satisfaction of other closing conditions. There is a risk of business disruption due to transaction-related uncertainty and potential negative effects on the Company's share price and financial performance. The Company undertakes no obligation to revise or update forward-looking statements.

Management Comments

• The Company believes that the claims asserted in the Lawsuits and the Demand Letters are without merit.
• The Company specifically denies all allegations set forth in the Lawsuits and the Demand Letters that any additional disclosure in the Proxy Statement was or is required.

Industry Context

The acquisition of Denny's by TriArtisan Capital Advisors, a private equity firm with existing restaurant holdings like PF Chang's, TGI Fridays, and Hooters, indicates ongoing consolidation and strategic investment within the casual dining and restaurant sector. The valuation analyses presented in the filing compare Denny's to a range of publicly traded and recently acquired restaurant companies, reflecting the competitive and dynamic nature of the industry.

Comparison to Industry Standards

• Selected public companies for comparison include Brinker International (6.4x EV/2026E Adjusted EBITDA), The Cheesecake Factory Incorporated (8.9x), Bloomin Brands, Inc. (4.6x), Dine Brands Global, Inc. (6.2x), First Watch Restaurant Group, Inc. (8.8x), Cracker Barrel Old Country Store, Inc. (6.1x), and BJ's Restaurants, Inc. (6.0x).
• Selected precedent transactions for comparison include Chuys (9.7x EV/LTM Adjusted EBITDA), Ruths Hospitality (8.0x), J. Alexanders Holdings (9.0x), Del Friscos Restaurant Group (12.3x), Bravo Brio Restaurant Group (6.1x), Fogo de Chao (9.4x), Ruby Tuesday (6.2x), Buffalo Wild Wings (10.2x), Bob Evans Restaurants (6.5x), Frischs (7.8x), Red Lobster (5.7x), CEC Entertainment (7.3x), PF Changs (8.8x), and California Pizza Kitchen (6.9x).
• The merger consideration of $6.25 per share for Denny's falls within the implied value reference range of $5.13 to $7.11 per share from the discounted cash flow analysis, suggesting it is within a reasonable valuation band based on internal projections, though direct comparison to the EV/EBITDA multiples of comparable companies/transactions would require further calculation based on the merger price.

Corporate Governance

Legal Proceedings

• Mark Thomas v. Dennys Corporation, et al. (Index No. 656541/2025), filed December 16, 2025, in the Supreme Court of the State of New York, County of New York, alleging the Proxy Statement was false and misleading and seeking to enjoin the Merger.
• James Walsh v. Dennys Corporation, et al. (Index No. 656542/2025), filed December 17, 2025, in the Supreme Court of the State of New York, County of New York, alleging the Proxy Statement was false and misleading and seeking to enjoin the Merger.
• Multiple demand letters from purported stockholders alleging deficiencies in the Proxy Statement's disclosures and threatening lawsuits if not addressed.

Stakeholder Impact

• Shareholders: Directly impacted by the merger consideration, the uncertainty introduced by litigation, and the need to make an informed voting decision at the upcoming special meeting.
• Employees: The acquirer intends to retain substantially all employees, but earlier indications of interest did not specify post-closing employment arrangements or equity participation by management.
• Management: Potential conflicts of interest faced by Company insiders are among the allegations in the shareholder lawsuits, which could impact their reputation and involvement in the merger process.

Next Steps

• The special meeting of stockholders is scheduled for January 13, 2026, to vote on the proposed merger.
• The Company will continue to address the ongoing shareholder litigation and demand letters.
• Consummation of the Merger, subject to stockholder approval, regulatory consents, and satisfaction of other closing conditions.

Key Dates

Recommendation

The stock is currently subject to a definitive merger agreement, which typically caps significant upside potential beyond the offer price unless a superior bid emerges. However, the ongoing shareholder litigation and the downward revision of 2025 financial projections introduce considerable uncertainty and risk to the deal's completion or timing. While the company is addressing disclosure concerns, the legal challenges and the fact that the final offer is significantly lower than initial indications suggest potential shareholder dissatisfaction. An investor should hold to monitor the outcome of the shareholder vote and litigation, as a 'sell' might be premature if the deal closes, and a 'buy' is speculative given the limited upside and legal risks.
