Jack in the Box Inc. Reiterates Confidence in "JACK on Track" Plan and Commitment to Maximizing Shareholder Value

Urges Shareholders to Vote "FOR" all 10 of Jack in the Box's Director Nominees, including David Goebel, Independent Chair of the Jack in the Box Board, on the WHITE Proxy Card

Jack in the Box Inc. ("Jack in the Box" or the "Company") (NASDAQ:JACK), today mailed a letter to shareholders in connection with its upcoming Annual Meeting of Shareholders scheduled to be held on February 27, 2026 (the "Annual Meeting"). Shareholders of record as of January 2, 2026 will be entitled to vote at the Annual Meeting.

In the letter, the Company highlights actions taken by Jack in the Box's strengthened Board in advancing the Company's "JACK on Track" plan, aimed at improving long-term financial performance, strengthening the balance sheet, and positioning the Company for sustainable growth. Further, in light of the "vote no" campaign launched by Biglari Capital Corp. (collectively with the participants in its solicitation, including Sardar Biglari, the "Biglari Group"), the letter urges shareholders to vote "FOR" all 10 of Jack in the Box's director nominees, including David Goebel, Independent Chair of the Jack in the Box Board, on the WHITE proxy card. Mr. Goebel brings critical expertise to Jack in the Box as one of the most qualified franchise executives in the quick-service restaurant and casual dining sector along with deep institutional knowledge of the Company, and his removal from the Board would jeopardize the continued successful execution of "JACK on Track" as well as the value of shareholders' investments in Jack in the Box.

The full text of the letter follows:

Dear Fellow Shareholders,

The 2026 Annual Meeting of Shareholders (the "Annual Meeting") of Jack in the Box Inc. (the "Company" or "Jack in the Box") is coming up on February 27, 2026, and we are writing to ask you to vote "FOR" ALL 10 of the Company's highly qualified director nominees and "FOR" each of the Company's proposals on the WHITE proxy card.

Your Board is excited about the future of the Company and its ability to build on the momentum the team has generated throughout the past year. Under the direction of the Company's new Chief Executive Officer Lance Tucker, Jack in the Box is executing a multi-faceted "JACK on Track" plan, aimed at improving long-term financial performance, strengthening the balance sheet, and positioning the Company for sustainable growth. The hard work is being done, tough measures are being taken – and we are making progress. While we recognize that much work remains, we believe that we are now building the strong foundation needed to maximize value for shareholders in the years ahead and we have to remain focused on continuing this critical process.

Despite this progress, Biglari Capital Corp. (collectively with the participants in its solicitation, including Sardar Biglari, the "Biglari Group") is asking shareholders to vote against the re-election of David Goebel, Independent Chair of the Jack in the Box Board. We believe voting against Mr. Goebel would be detrimental to shareholders, potentially depriving the Board of the critical expertise that Mr. Goebel brings to the Company as one of the most qualified franchise executives in the quick-service restaurant and casual dining sector, and jeopardizing the successful execution of our "JACK on Track" plan.

Importantly, members of the Board and management team have held numerous meetings with representatives of the Biglari Group, including Mr. Biglari, over many months as part of our commitment to constructive shareholder engagement. During these discussions, the Board evaluated the candidacy of Mr. Biglari for our Board at his request and ultimately determined he was not well suited to serve as a director. Although our Board continued to pursue constructive engagement, the Biglari Group instead launched a distracting proxy contest, nominating Mr. Biglari and another director candidate to the Board. While the Biglari Group ultimately withdrew both of its candidates, your Board continued to engage in good faith to identify a path toward a mutually agreeable outcome that would be in the best interests of our shareholders. Despite the Board's efforts, the Biglari Group has now launched a "vote no" campaign against Mr. Goebel, which we believe is intended to advance the Biglari Group's own interests rather than those of all Jack in the Box shareholders.

Jack in the Box currently benefits from a strong, experienced Board comprising ten proven directors – nine of whom are independent – and all of whom are dedicated to driving shareholder value as Jack in the Box continues its transformation. In collaboration with another Jack in the Box shareholder, we recently refreshed the Board by adding two directors who bring expertise in restaurants, retail, and real estate – especially in California. We believe that removing the Chair of our Board as a result of the Biglari Group's campaign would significantly weaken the Board's ability to oversee our execution of "JACK on Track" and put the future value of your investment at risk.

"JACK on Track": Unlocking the Future of Jack in the Box

For 75 years, Jack in the Box has grown through strong franchisees, loyal customers, and talented team members. By late 2024, however, the Company's focus on these fundamentals had wavered as it faced macroeconomic and unique industry headwinds putting pressure on Jack in the Box's business and core consumer base.

To restore focus and capitalize on our strengths, the Board appointed Lance Tucker as Chief Executive Officer in March 2025. Mr. Tucker is an experienced business leader with decades of restaurant experience including as Chief Financial Officer at Davidson Hospitality Group, CKE Restaurants, and Papa John's International, where he also served as Chief Administrative Officer. His financial expertise and decades of experience within the restaurant industry, including prior executive roles at Jack in the Box, make him the right person to lead the Company through its next phase. Mr. Tucker has assembled a seasoned management team, including a new Chief Financial Officer and Chief Operating Officer, focused on restoring what makes the brand special. In April 2025, soon after Mr. Tucker's appointment, the Board approved the "JACK on Track" plan, built on three priorities:

• Accelerate cash flow and pay down debt while preserving growth-oriented capital investments;

• Strengthen Franchisee Economics by introducing a block closure program to improve system health and position Jack in the Box for consistent net unit growth; and

• Return to simplicity and focus on the Jack in the Box asset-light model.

Since the launch of the plan, the team has been delivering on the promises the Company made by undertaking a comprehensive series of actions to implement these key priorities. Mr. Tucker is committed to overseeing the hard work needed to address the Company's problems. It is critical Mr. Tucker and his experienced team be able to focus on the business and maintain the momentum underway. Jack in the Box is proud of the progress we have made thus far in our transformation journey.

"Jack's Way": Increasing Profitability by Elevating the Guest Experience

Alongside "JACK on Track," we launched "Jack's Way" to strengthen the basics that keep guests coming back – consistent operations, food quality, and guest experience. We are enhancing our training and driving operational consistency under the leadership of Chief Operating Officer Shannon McKinney, while developing innovative new menu offerings under our newly-hired Executive Chef. We are also modernizing select locations and investing in technology and digital capabilities to enhance efficiency and appeal. These efforts are already earning positive feedback and increasing customer satisfaction.

Our focus is on simplifying the brand, attracting guests with an improved offering, and making disciplined financial decisions to deliver sustained profitability and long-term shareholder value.

The Full Board is Essential to Successfully Overseeing the Execution of "JACK on Track"

Jack in the Box currently benefits from a deeply experienced Board with skills critical to our business and strategy, including expertise in the food service, franchising, and hospitality industries. Collectively, our directors have led major brand transformations, steered complex operational turnarounds, and delivered long-term growth in competitive environments. Their decades of leadership ensure rigorous oversight and focus on optimizing the "JACK on Track" plan.

Mr. Goebel, in particular, is one of the most qualified franchise executives in the quick-service restaurant and casual dining sector, with expertise that is highly important to Jack in the Box as a 93% franchised system. Mr. Goebel is the former Chief Executive Officer of Applebee's, built and operated 80 Boston Market locations and has founded and scaled multiple franchise concepts with experience as both a franchisor and franchisee that enables the Board to remain closely attuned to operator dynamics. Further, Mr. Goebel provides deep institutional knowledge from his tenure on the Board and provides stability and long-term context as the Company executes its "JACK on Track" plan.

We are committed to strong governance and having the right Board to oversee the execution of our plan. To bring fresh perspectives, we have added three independent directors over the past three years, including Mark King and Alan Smolinisky, who were appointed to the Board in November 2025 as part of a cooperation agreement with one of the Company's large shareholders, GreenWood Investors, LLC. These additions reflect constructive engagement with shareholders and strengthen the Board with relevant expertise in restaurants, retail, and real estate – especially in California.

To allow the newly refreshed Board and management team to benefit from Mr. Goebel's extensive expertise relevant to the Company and execution of the "JACK on Track" plan, the Board and management team asked Mr. Goebel to remain in his position through the Company's 2027 Annual Meeting of Shareholders. This one-year extension to Mr. Goebel's directorship will enable the Board and management to continue to benefit from his operating, franchisee, and governance experience, before his retirement from board service next year. Voting against Mr. Goebel will serve only to potentially deprive our Board and shareholders of his invaluable knowledge and experience during a critical turnaround period.

With Mr. Goebel and our enhanced Board laser-focused on overseeing the execution of "JACK on Track," we believe Biglari's "vote no" campaign is an unnecessary distraction driven by Mr. Biglari's desire to advance his own interests and not the best interests of all shareholders.

Don't Risk Derailing Execution of a Plan that is Already Delivering Results

We are confident that with Mr. Goebel's leadership of our expert and recently refreshed Board and under the direction of our new Chief Executive Officer, Lance Tucker, the actions we are taking support the successful execution of the "JACK on Track" plan and will create value for shareholders.
