Other Events. On August 17, 2026, JAB Acquisition Corp I. (the “Company”) entered into a trademark settlement agreement (the “Settlement Agreement”) with a third party (the “Claimant”) to amicably resolve an outstanding trademark claim regarding the Company's name and its trading symbol. Under the terms of the Settlement Agreement, and to prevent any potential market or consumer confusion with the Claimant’s prior registered marks, the Company has agreed to alter its market presence. Consequently, the Company has filed a request with the Nasdaq Stock Market LLC (“Nasdaq”) to voluntarily change its trading ticker symbol. The Company expects its Class A ordinary shares, units, warrants and rights to begin trading under the new ticker symbols ATLQ, ATLQU, ATLQW and ATLQR, respectively, on a date to be announced following confirmation from Nasdaq. No action is required by the current shareholders of the Company. The change in trading ticker symbols described above does not affect the validity of any outstanding stock certificates, the ownership percentage of the existing shareholders or the underlying capital structure of the Company. The Company's CIK number will remain unchanged. In addition, pursuant to the terms of the Settlement Agreement, the Company intends to change its name to Atlantic Acquisition Corp I. This name change shall become effective upon approval by the board of directors and the shareholders of the Company. Item 9.01. Financial Statements and Exhibits.
