CONTENTS

As previously disclosed, on October 28, 2024, Lilium GmbH and Lilium eAircraft GmbH, the principal operating wholly-owned German subsidiaries (the “Subsidiaries”) of Lilium N.V. (the “Company” or “Lilium”) (together with the Subsidiaries, the “Companies”), filed for insolvency under German law and applied for self-administration proceedings in Germany, which the court approved. The court opened preliminary insolvency proceedings which are on-going. On November 6, 2024, the Company filed a motion for opening of regular insolvency proceedings with the competent insolvency court in Germany and on November 8, 2024, the court appointed a preliminary insolvency administrator especially to maintain and secure the assets of the Company and continue the business operations of the Company. During these insolvency proceedings, the Companies are currently in the process of seeking investors for one or more potential transactions, including financing, and conducting a process to sell their assets and/or business. There can be no assurance that the Subsidiaries or the Company will be successful in raising financing or selling their assets and/or business. The Company does not presently expect that there will be any proceeds for the Company or its shareholders as a result of any such activities. Additional information and background on the Companies’ applications for these proceedings may be found in Lilium N.V.’s Form 6-Ks filed with the U.S Securities and Exchange Commission (the “SEC”) on October 24, 2024, October 28, 2024, October 29, 2024, November 4, 2024, November 6, 2024, and November 12, 2024.

On December 5, 2024, Lilium GmbH published a press release announcing certain updates on Lilium GmbH’s business. Lilium GmbH also reported that the KPMG-led M&A process continues.

In addition, Lilium GmbH has signed a binding sales agreement with The Ambitious Group for 8 Lilium Jets, with an option for 6 additional aircraft. This binding sales agreement follows the initial letter of intent between The Ambitious Group and Lilium GmbH signed in March 2024. Implementation of the order is subject to Lilium GmbH’s successful return to solvency. In conjunction with the start of Lilium GmbH’s preliminary insolvency proceedings, Benelux-based business jet operator ASL Group BV (“ASL Group”) cancelled the delivery slot reservation agreement, dated May 23, 2023, as amended on November 22, 2023, between Lilium GmbH and ASL Group for the delivery of six Lilium Pioneer Edition Jets pursuant to the terms of such agreement. The two parties intend to reengage following a successful conclusion of Lilium GmbH’s financial restructuring.

The press release is furnished as Exhibit 99.1 to this Report on Form 6-K.

In connection with the Subsidiaries’ insolvency proceedings, certain subsidiaries of Lilium GmbH (the “GmbH Subsidiaries”) are currently in the process of winding up.
