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. On November 6, 2024, the Company filed a motion for opening of regular insolvency proceedings with the competent insolvency court in Germany. The preliminary insolvency proceedings pertaining to the Companies are on-going. 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, November 12, 2024, December 5, 2024, and December 16, 2024.

As previously reported on Form 6-Ks filed on December 5, 2024, and on December 16, 2024, KPMG has been in discussions with potential investors who have indicated interest in the assets and/or business of the Subsidiaries, which interests have been considered by Lilium GmbH’s creditor’s committee as part of the KPMG-led M&A process aimed at delivering Lilium GmbH’s financial restructuring. On December 23, 2024, the Subsidiaries signed an asset purchase agreement (the “Agreement”) with Mobile Uplift Corporation GmbH, a company set up by an experienced consortium of investors from Europe and North America, pursuant to which the purchaser intends to acquire the operating assets of the Subsidiaries. Subject to the satisfaction of certain conditions precedent, the Subsidiaries expect that the Agreement positions the Subsidiaries to obtain sufficient funding to restart their business operations. Proceeds received from the sale will be utilized according to German Insolvency Law. Lilium will not receive proceeds from the sale which will enable it to make any distributions to shareholders.

Under the terms of the Agreement, closing is currently expected in early January 2025 and is subject to the satisfaction of certain customary conditions precedent, including opening of the proceedings and consent of the creditors committee. The aim of Agreement and the transactions contemplated therein is the planned restructuring of the Subsidiaries, which is intended to enable the Subsidiaries to exit their self-administration proceedings. On December 20, 2024, the Subsidiaries terminated the contracts of their remaining employees in accordance with German law. Following the anticipated closing of the transactions, the Subsidiaries will initiate appropriate instruments in relation to employees whose employment contracts were terminated on December 20, 2024.

In addition, Lilium expects the court of Weilheim in Germany to open regular insolvency proceedings pertaining to the Company on December 30, 2024, at which time it is expected that Lilium will commence the process of winding up and all existing employment contracts with the Company will be terminated in accordance with German law.
