Explanatory Note

On November 18, 2022, Lilium N.V. (the “Company”) entered into definitive agreements with certain qualified investors for the purchase and sale, in a private placement (the “PIPE”), of (i) 69,024,939 of the Company’s class A ordinary shares, nominal value €0.12 per share (“Class A Shares”), at a price of $1.30 per share, and (ii) warrants exercisable for an aggregate of 34,512,466 Class A Shares, with an exercise price of $1.30 per share. In addition, the Company commenced a registered direct offering (the “Registered Direct Offering”) to issue to other qualified investors (i) 22,499,997 Class A Shares, at a price of $1.30 per share, and (ii) warrants exercisable for an aggregate of 11,249,997 Class A Shares, with an exercise price of $1.30 per share. Citigroup Capital Markets Inc., B. Riley Securities, Inc. and Piper Sandler & Co. are acting as placement agents for both offerings. The closing of the Registered Direct Offering is not conditioned on the closing of the PIPE, but the closing of the PIPE is conditioned on the Company raising at least $115.0 million in gross proceeds, in the aggregate, in the Registered Direct Offering and the PIPE. See "Funding Needs" in Exhibit 99.1 attached hereto.

The Class A Shares being sold pursuant to the Registered Direct Offering are being offered by the Company pursuant to an effective shelf registration on Form F-3, which was originally filed with the Securities and Exchange Commission (the “SEC”) on October 3, 2022 (File No. 333-267719) and declared effective on October 12, 2022.

The PIPE and the Registered Direct Offering are expected to close on or around November 22, 2022, or shortly thereafter in the case of the PIPE.

This Report on Form 6-K shall not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

Attached as Exhibit 99.1 to this Report on Form 6-K is an update regarding certain business information relating to the Company, and attached as Exhibit 99.2 is an updated description of the Company’s capital stock reflecting the general meeting held in October 2022.
