On June 30, 2024, Spirit entered into an Agreement and Plan of Merger (as it may be amended from time to time, the “Merger Agreement”), with The Boeing Company (“Boeing”) and Sphere Acquisition Corp., a wholly owned subsidiary of Boeing (“Merger Sub”), providing for the merger of Merger Sub with and into Spirit (the “Merger”), and for Spirit to be the surviving corporation in the Merger. Upon completion of the Merger, Spirit would be a wholly owned subsidiary of Boeing. Spirit stockholders approved the Merger Agreement at a special stockholders meeting held on January 31, 2025. No other action by Spirit stockholders is required with respect to the Merger. Accordingly, no action will be taken at the Annual Meeting with respect to, and no proxy is being solicited in connection with, the Merger. If the Merger is completed prior to the commencement of the Annual Meeting on May 23, 2025, the Annual Meeting will not be held.
