Jack in the Box Inc. (“Jack in the Box” or the “Company”) (NASDAQ: JACK), today announced that leading independent proxy advisory firm Institutional Shareholder Services (“ISS”) has recommended that Jack in the Box shareholders vote “FOR” all 10 of the Company’s director nominees, including David Goebel, Independent Chair of the Jack in the Box Board, on the WHITE proxy card in connection with the 2026 Annual Meeting of Shareholders (the “Annual Meeting”) scheduled to be held on February 27, 2026. Both ISS and Glass Lewis recommend shareholders vote “FOR” the Company’s shareholder rights plan.

In its report dated February 13, 2026, ISS noted:¹

• “Not only does disclosure suggest that the board chair postponed his planned retirement prior to this meeting at the request of the new CEO, but it is difficult to substantiate the dissident's contention that there is urgency to remove him.”
  

• “…the dissident's focus on Goebel as the primary source of underperformance does not fully account for adverse macroeconomic developments over the period.”
  

• “…the board has demonstrated a willingness to engage constructively with shareholders, as proven by its fruitful settlement with GreenWood, through which Smolinisky was added.”
  

• “…the combination of constructive shareholder engagement, appropriate refreshment, and the circumstances and timeline surrounding the planned departure of the board chair, who is the sole target of the dissident in this campaign, suggest that the change sought by the dissident is not warranted at this time.”

In addition, regarding the Company’s shareholder rights plan, in their reports dated February 13, 2026 and February 14, 2026, respectively, ISS and Glass Lewis noted:¹

• “The proposed poison pill contains reasonable features that protect shareholders from entrenchment risk as well as potentially abusive takeover tactics by dissident shareholders, and thus there is little downside risk to unaffiliated shareholders from continuation of the pill.” – ISS
  

• “…in this instance, the board has presented reasonable justification for adopting the new rights plan, particularly in light of the situation between the board and Biglari…given the circumstances, the Benchmark Policy takes the view that the Company has made a reasonable case for shareholders to support this particular rights plan.” – Glass Lewis

Jack in the Box issued the following statement:

“We are pleased that ISS recognizes the strength and experience of our Board, highlights our responsiveness to shareholder feedback, and affirms our recommendation that shareholders vote on the WHITE proxy card “FOR” all 10 of the Company’s highly qualified director nominees so we can continue overseeing the successful execution of our “JACK on Track” plan. Importantly, ISS confirms the Company’s view that the campaign run by Biglari Capital Corp. (collectively with the participants in its solicitation, including Sardar Biglar, the “Biglari Group”) does not serve in the best interests of all Jack in the Box shareholders and that the re-election of David Goebel, Independent Chair of the Jack in the Box Board, is especially important during this critical time.

Further, we strongly believe that Glass Lewis reached the wrong conclusion in failing to recommend shareholders vote for Mr. Goebel. Mr. Goebel has demonstrated strong leadership as the Board has overseen strategic actions to put the Company back on track and he brings deep understanding of the Company and extensive relevant operating, franchising, and governance expertise that are especially important at this critical time as we continue the successful execution of our “JACK on Track” and “Jack’s Way” plans.

We continue to believe that Mr. Biglari’s campaign is not driven out of genuine desire to create shareholder value, but rather by his self-interest and anger at the Board’s unanimous decision that he was not well suited to join the Board. While we recognize that much work remains, we are confident that with the leadership of our entire expert and recently refreshed Board and our new management team, we can rebuild value for ALL shareholders.”

Your vote is important. We encourage you to protect the value of your investment in Jack in the Box by voting “FOR” ALL 10 of the Company’s highly qualified director nominees and “FOR” the other proposals on the agenda on the WHITE proxy card today. Please simply disregard any gold proxy card you may receive from the Biglari Group. For more information, please visit: www.KeepJackonTrack.com.
