PRELIMINARY — SUBJECT TO COMPLETION, DATED JUNE 10, 2021

LETTER TO SHAREHOLDERS OF QELL ACQUISITION CORP.

Qell Acquisition Corp.
505 Montgomery Street, Suite 1100
San Francisco, California 94111

Dear Qell Acquisition Corp. Shareholder:

You are cordially invited to attend an extraordinary general meeting of Qell Acquisition Corp., a Cayman Islands exempted company (“Qell”), which will be held on , 2021 at 9:00 a.m., New York City time, at the offices of Goodwin Procter LLP located at 620 Eighth Avenue, New York, New York 10018 (the “General Meeting”).

On March 30, 2021, Qell, Lilium GmbH, a German limited liability company (“Lilium”), Lilium B.V., a Dutch private liability company (besloten vennootschap met beperkte aansprakelijkheid) (which will be converted into a Dutch public limited liability company (naamloze vennootschap) (“Holdco”)) prior to closing of the Business Combination), and Queen Cayman Merger LLC, a Cayman Islands limited liability company and wholly owned subsidiary of Holdco (“Merger Sub”) entered into a Business Combination Agreement (as it may be amended from time to time, the “Business Combination Agreement”), pursuant to which certain transactions will occur, and in connection therewith, Holdco will become the ultimate parent company of Lilium and, prior to the immediate commencement of winding up proceedings, Merger Sub, the surviving entity in a merger with Qell (the “Business Combination”). Merger Sub made an election, effective as of the date of its formation, to be treated as an entity disregarded from Holdco for U.S. federal income tax purposes.

At the General Meeting, Qell shareholders will be asked to consider and vote upon: (i) a proposal, as an ordinary resolution (the “Business Combination Proposal”), to adopt and approve the Business Combination Agreement, a copy of which is attached to the accompanying proxy statement/prospectus as Annex A, and the transactions contemplated thereby, including the Business Combination (Proposal No. 1), (ii) a proposal, as a special resolution (the “Merger Proposal”) to authorise and approve the Plan of Merger pursuant to which Qell will merge with and into Merger Sub, with Merger Sub as the surviving company in accordance with the relevant provisions of the Cayman Islands Acts (the “Merger”), and the remaining transactions contemplated thereby (Proposal No. 2), (iii) a proposal, as an ordinary resolution (the “Incentive Plan Proposal”) to adopt and approve the Holdco 2021 Equity Incentive Plan (the “Incentive Plan”), which will be substantially in the form attached to the accompanying proxy statement/prospectus as Annex C, including the authorization of the initial share reserve under the Incentive Plan (Proposal No. 3), and (iv) a proposal, as an ordinary resolution (the “ESPP Proposal”) to adopt and approve the Holdco 2021 Employee Share Purchase Plan (the “ESPP”), a copy of which is attached to this proxy statement/prospectus as Annex D, including the authorization of the initial share reserve under the ESPP (Proposal No. 4).

As further described in the accompanying proxy statement/prospectus, subject to the terms and conditions of the Business Combination Agreement, upon consummation of the Business Combination, among other things:

•

Qell will merge with and into Merger Sub, with Merger Sub as the surviving company (the “Surviving Company”) in the Merger;

•

In connection with the Merger, each issued and outstanding ordinary share of Qell will be converted into a claim for a corresponding equity security in the Merger Sub, and such claim shall then be contributed into Holdco in exchange for one class A ordinary share in the share capital of Holdco (a “Holdco Class A Share”);

•

Immediately following the Merger, Holdco will cause Merger Sub to, and Merger Sub will, commence winding up under the Cayman LLC Act and distribute all of its tangible and intangible assets (including all cash) and transfer any and all of its liabilities to Holdco (the “Liquidation Distribution and Assumption”);

•

Immediately following the Liquidation Distribution and Assumption, Holdco will take a series of actions including, but not limited to, (i) appointment of Daniel Wiegand as executive director to the board of directors of Holdco, and (ii) execution of the Holdco Board Agreements (as defined in the Business Combination Agreement);

TABLE OF CONTENTS

•

The shareholders of Lilium (“Participating Shareholders”) will exchange (the “Exchange”) their Lilium shares for shares in the capital of Holdco (“Holdco Shares”). All Lilium shareholders, but for Daniel Wiegand, will receive Holdco Class A Shares in the Exchange. Daniel Wiegand will receive class B ordinary shares in the share capital of Holdco (“Holdco Class B Shares”). Holdco Class B Shares will rank pari passu with Holdco Class A Shares in all respects, provided they will be entitled to 3x super voting rights, subject to customary sunset provisions; and

•

Each outstanding warrant to purchase a Qell Class A Ordinary Share will, by its terms, convert into a warrant to purchase one Holdco Class A Share, on the same contractual terms (“Holdco Public Warrants”).

In connection with the foregoing and concurrently with the execution of the Business Combination Agreement, Qell and Holdco entered into Subscription Agreements (the “Subscription Agreements”) with certain investors (the “PIPE Investors”), pursuant to which the PIPE Investors agreed to subscribe for and purchase, and Holdco agreed to issue and sell to such PIPE Investors, an aggregate of 45,000,000 Holdco Shares at $10.00 per share for gross proceeds of $450,000,000 (the “PIPE Financing”) on the Final Closing Date. The Holdco Shares to be issued pursuant to the Subscription Agreements have not been registered under the Securities Act in reliance upon the exemption provided in Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder. Holdco will grant the PIPE Investors certain registration rights in connection with the PIPE Financing. The PIPE Financing is contingent upon, among other things, the closing of the Business Combination.

Additionally, in connection with their entry into the Business Combination Agreement, Qell and Holdco entered into a letter agreement (the “Sponsor Letter Agreement”) with Qell Partners LLC (the “Sponsor”) and Lilium, pursuant to which the Sponsor has agreed (a) to vote in favor of the Business Combination Agreement and the transactions contemplated thereby and take all actions reasonably necessary to cause the closing of the Business Combination, including execution of the Holdco shareholder approval, (b) to waive any adjustment to the conversion ratio set forth in the Qell’s amended and restated memorandum and articles of association or any other anti-dilution or similar protection with respect to the Qell Class B Ordinary Shares held by them, and (c) forfeit 1,828,945 Qell Class B Ordinary Shares that would otherwise have converted into 1,828,945 Holdco Class A Shares in connection with the Merger for no consideration, and subject 3,063,422 of the Holdco Shares acquired by the Sponsor in connection with the Merger (in addition to any New Shares (as defined in the Sponsor Letter Agreement) issued with respect to such Holdco Shares) to certain time and performance vesting provisions.

It is anticipated that, upon completion of the Business Combination: (i) Qell’s public shareholders will receive approximately 12% of Holdco Shares and 11% of the voting rights; (ii) the PIPE Investors will receive approximately 15% of Holdco Shares and 12% of the voting rights; (iii) the Sponsor will receive approximately 2% of Holdco Shares and 2% of the voting rights; and (iv) the Participating Shareholders will receive approximately 71% of Holdco Shares and 75% of the voting rights. These ownership levels in Holdco assume the following: (i) no redemptions by the public shareholders, (ii) that the amount in the Trust Account is $379,600,000 (which was the approximate value of the Trust Account as of December 31, 2020, not taking into account $13,282,500 of deferred underwriting fees to be paid), (iii) Participating Shareholders represent 100% of the issued and outstanding shares of Lilium and there are no “change of control” payments made or required to be made by Lilium, and (iv) that PIPE Investors fund the PIPE Financing in full in accordance with the Subscription Agreements.

In addition to the Business Combination Proposal, the Merger Proposal, the Incentive Plan Proposal, and the ESPP Proposal, Qell shareholders are being asked to consider and vote upon a proposal to adjourn the General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if there are insufficient votes for, or otherwise in connection with, the approval of the Business Combination Proposal (Proposal No. 1) and the Merger Proposal (Proposal No. 2) (the “Adjournment Proposal”). The Adjournment Proposal (Proposal No. 5) will only be presented to Qell shareholders in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Business Combination Proposal or the Merger Proposal. Each of these proposals is more fully described in this proxy statement/prospectus, which each shareholder is encouraged to read carefully.

The Qell Class A Ordinary Shares, Qell Public Units and Qell Public Warrants are currently listed on the Nasdaq Capital Market (“Nasdaq”) under the symbols “Qell,” “QellU” and “QellW,” respectively. Upon the closing of the Business Combination, the Qell securities will be delisted from Nasdaq. Holdco intends to apply to list the Holdco Class A Shares and Holdco Public Warrants on Nasdaq under the symbols

TABLE OF CONTENTS

“LILM” and “LILMW” respectively, upon the closing of the Business Combination. We cannot assure you that the Holdco Shares or Holdco Public Warrants will be approved for listing on Nasdaq.

Holdco is an “emerging growth company” under applicable United States federal securities laws and will be subject to reduced public company reporting requirements. Investing in Holdco’s securities involves a high degree of risk. See “Risk Factors” beginning on page 44 of the accompanying proxy statement/prospectus for a discussion of information that should be considered in connection with an investment in Holdco’s securities.

With respect to Qell and the holders of the Qell Ordinary Shares, the accompanying proxy statement/prospectus serves as a:

•

proxy statement for the extraordinary general meeting of Qell shareholders being held on , 2021, where Qell shareholders will vote on, among other things, proposals to adopt, approve and authorize each of the Business Combination Agreement and the Plan of Merger, and the transactions contemplated thereby; and

•

prospectus for the Holdco Shares and Holdco Public Warrants that Qell shareholders, Lilium shareholders and public warrant holders will receive in the Business Combination.

Pursuant to the Qell amended and restated memorandum and articles of association, Qell is providing its public shareholders with the opportunity to redeem, upon the closing of the Business Combination, Qell Class A Ordinary Shares then held by them for cash equal to their pro rata share of the aggregate amount then on deposit (as of two business days prior to the closing of the Business Combination) in the trust account established by Qell containing the proceeds of Qell’s initial public offering (the “Qell IPO”) and from certain private placements occurring simultaneously with the Qell IPO for the benefit of Qell’s public shareholders (the “Trust Account”). Redemptions referred to herein shall take effect as repurchases under the Qell amended and restated memorandum and articles of association (the “Qell Shareholder Redemption”). The per-share amount Qell will distribute to investors who properly redeem their Qell Class A Ordinary Shares will not be reduced by the aggregate deferred underwriting commission of $13,282,500 that Qell will pay to the underwriters of the Qell IPO or transaction expenses incurred in connection with the Business Combination. For illustrative purposes, based on the fair value of marketable securities held in the Trust Account of approximately $ as , 2020, the estimated per Qell Class A Ordinary Share redemption price would have been approximately $ .The redemption rights include the requirement that a holder must identify itself in writing as a beneficial holder and provide its legal name, phone number and address to the Transfer Agent in order to validly redeem its shares. Public shareholders may elect to redeem their shares even if they vote for the Business Combination Proposal. A public shareholder, together with any of his, her or its affiliates or any other person with whom it is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, in excess of 15% of the outstanding Qell Class A Ordinary Shares (i.e., in excess of 5,692,500 Qell Class A Ordinary Shares). Each redemption of Qell Class A Ordinary Shares by Qell’s public shareholders will reduce the amount in the Trust Account. The Business Combination Agreement provides that Lilium’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (after giving effect to the Qell Shareholder Redemption) together with the proceeds actually received from the PIPE Financing being at least $450,000,000 (the “Aggregate Holdco Transaction Proceeds Condition”). The committed PIPE subscriptions are sufficient to satisfy this condition if fully funded, even if existing Qell shareholders exercise their redemption rights.

The conditions to closing in the Business Combination Agreement are for the sole benefit of the parties thereto and may be waived by such parties. In no event will Qell redeem its Qell Class A Ordinary Shares in an amount that would cause its (or Holdco’s after giving effect to the Business Combination) net tangible assets to be less than $5,000,001, as provided in the Qell amended and restated memorandum and articles of association and as required as a closing condition to each party’s obligation to consummate the Business Combination under the terms of the Business Combination Agreement. Holders of outstanding Qell Public Warrants do not have redemption rights in connection with the Business Combination. Unless otherwise specified, the information in the accompanying proxy statement/prospectus assumes that (i) none of Qell’s public shareholders exercise their redemption rights with respect to their Qell Class A Ordinary Shares and (ii) Lilium shareholders represent 100% of the issued and outstanding shares of Lilium and there are no “change of control” payments made or required to be made by Lilium. For more information about the factors that affect the assumptions above, please see the section entitled “The Business Combination — Ownership of Holdco.”

TABLE OF CONTENTS

The Sponsor has agreed to waive its redemption rights with respect to any Qell Ordinary Shares held by the Sponsor in connection with the consummation of the Business Combination (the “Founder Shares”), and such shares will be excluded from the pro rata calculation used to determine the per-share redemption price. Currently, the Sponsor owns 20% of the issued and outstanding Qell Ordinary Shares, including all of the Founder Shares. The Sponsor has agreed to vote any Qell Ordinary Shares owned by them in favor of the Business Combination and the transactions contemplated thereby. The Founder Shares are subject to transfer restrictions. The Qell amended and restated memorandum and articles of association includes a conversion adjustment which provides that the Founder Shares will automatically convert at the time of the Business Combination into a number of Qell Class A Ordinary Shares one day after the closing of the Business Combination, at a conversion rate that entitles the holders of such Founder Shares to continue to own, in the aggregate, 20% of the issued and outstanding Qell Ordinary Shares after giving effect to the PIPE Financing. However, the Sponsor has agreed to waive such conversion adjustment pursuant to the Sponsor Letter Agreement. As a result, each remaining Founder Share will be exchanged for one Holdco Share at the closing of the Business Combination, such that the Sponsor will hold approximately 2.3% (on a fully diluted basis) of the total number of Holdco Shares outstanding after the consummation of the Business Combination. Please see the section entitled “Frequently Used Terms and Basis of Presentation” in the accompanying proxy statement/prospectus for assumptions relating to this calculation.

Qell is providing the accompanying proxy statement/prospectus and accompanying proxy card to its shareholders in connection with the solicitation of proxies to be voted at the General Meeting and at any adjournments or postponements of the General Meeting. Information about the General Meeting, the Business Combination, the Merger and other related business to be considered by the Qell shareholders at the General Meeting is included in the accompanying proxy statement/prospectus. Whether or not you plan to attend the General Meeting, all Qell shareholders are urged to read carefully the accompanying proxy statement/prospectus, including the Annexes and the accompanying financial statements of Holdco, Qell and Lilium carefully and in their entirety. In particular, you are urged to read carefully the section entitled “Risk Factors” beginning on page 43 of the accompanying proxy statement/prospectus.

After careful consideration, the Qell Board has approved the Business Combination Agreement, the Business Combination and the Merger, and recommends that Qell shareholders vote “FOR” the Business Combination Proposal, “FOR” the Merger Proposal, “FOR” the Incentive Plan Proposal, “FOR” the ESPP Proposal, and “FOR” all other proposals presented to Qell shareholders in the accompanying proxy statement/prospectus. When you consider the Qell Board’s recommendation of these proposals, you should keep in mind that certain Qell directors and officers have interests in the Business Combination that may conflict with your interests as a shareholder. Please see the section entitled “The Business Combination — Interests of Certain Persons in the Business Combination” in the accompanying proxy statement/prospectus for additional information.

Approval of the Merger Proposal requires the affirmative vote of holders of at least two-thirds of the Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. Approval of the Business Combination Proposal, the Incentive Plan Proposal, the ESPP Proposal, and the Adjournment Proposal each require the affirmative vote of holders of a majority of the Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting.

Your vote is very important. Whether or not you plan to attend the General Meeting, please vote as soon as possible by following the instructions in the accompanying proxy statement/prospectus to ensure that your shares are represented at the General Meeting. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that your shares are represented and voted at the General Meeting. The transactions contemplated by the Business Combination Agreement, including the Merger, will be consummated only if both the Business Combination Proposal and the Merger Proposal are approved at the General Meeting. The closing of the Business Combination is conditioned upon the approval of the Business Combination Proposal and the Merger Proposal. The Incentive Plan Proposal and ESPP Proposal are conditioned on the approval of the Business Combination Proposal and the Merger Proposal. If both the Business Combination Proposal and the Merger Proposal are not approved, the Incentive Plan Proposal and the ESPP Proposal will have no effect, even if approved by our shareholders. The Adjournment Proposal is not conditioned on the approval of any other proposal set forth in the accompanying proxy statement/prospectus.

If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted “FOR” each of the proposals presented at the General Meeting. If you fail to return your proxy card or fail to instruct your bank, broker or other nominee how to vote, and do not attend the General

TABLE OF CONTENTS

Meeting in person, the effect will be, among other things, that your shares will not be counted for purposes of determining whether a quorum is present at the General Meeting. If you are a shareholder of record and you attend the General Meeting and wish to vote in person, you may withdraw your proxy and vote in person.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST DEMAND THAT QELL REDEEM YOUR SHARES FOR A PRO RATA PORTION OF THE FUNDS HELD IN THE TRUST ACCOUNT AND TENDER YOUR SHARES TO THE TRANSFER AGENT AT LEAST TWO BUSINESS DAYS PRIOR TO THE INITIALLY SCHEDULED VOTE AT THE GENERAL MEETING. THE REDEMPTION RIGHTS INCLUDE THE REQUIREMENT THAT A HOLDER MUST IDENTIFY HIMSELF, HERSELF OR ITSELF IN WRITING AS A BENEFICIAL HOLDER AND PROVIDE HIS, HER OR ITS LEGAL NAME, PHONE NUMBER AND ADDRESS TO THE TRANSFER AGENT IN ORDER TO VALIDLY REDEEM HIS, HER OR ITS SHARES. YOU MAY TENDER YOUR SHARES BY EITHER DELIVERING YOUR SHARE CERTIFICATE TO THE TRANSFER AGENT OR BY DELIVERING YOUR SHARES ELECTRONICALLY USING DEPOSITORY TRUST COMPANY’S DWAC (DEPOSIT WITHDRAWAL AT CUSTODIAN) SYSTEM. IF THE BUSINESS COMBINATION IS NOT COMPLETED, THEN THESE SHARES WILL NOT BE REDEEMED FOR CASH. IF YOU HOLD THE SHARES IN STREET NAME, YOU WILL NEED TO INSTRUCT THE ACCOUNT EXECUTIVE AT YOUR BANK OR BROKER TO WITHDRAW THE SHARES FROM YOUR ACCOUNT IN ORDER TO EXERCISE YOUR REDEMPTION RIGHTS.

On behalf of the Qell Board, I would like to thank you for your support of Qell and look forward to a successful completion of the Business Combination.

Sincerely,

, 2021

TABLE OF CONTENTS

The record date for the General Meeting for Qell shareholders that hold their shares in “street name” is for Qell shareholders holding their shares in “street name”, only shareholders at the close of business on that date may vote at the General Meeting or any adjournment thereof. For the avoidance of doubt, the record date does not apply to Qell shareholders that hold their shares in registered form and are registered as shareholders in Qell’s register of members. Qell shareholders that hold their shares in registered form are entitled to one vote on each proposal presented at the General Meeting for each Qell Ordinary Share held on the date of the General Meeting.

As further described in this proxy statement/prospectus, subject to the terms and conditions of the Business Combination Agreement, upon consummation of the Business Combination, among other things:

•

Qell will merge with and into Merger Sub (the “Merger”), with Merger Sub as the surviving company (the “Surviving Company”) in the Merger;

•

The shareholders of Lilium (the “Participating Shareholders”) will exchange (the “Exchange”) their Lilium shares for shares in the capital of Holdco (“Holdco Shares”). All Lilium shareholders, but for Daniel Wiegand, will receive Holdco Class A Shares in the Exchange. Daniel Wiegand will receive class B ordinary shares in the share capital of Holdco (“Holdco Class B Shares”). Holdco Class B Shares will rank pari passu with Holdco Class A Shares in all respects, provided they will be entitled to 3x super voting rights, subject to customary sunset provisions; and

•

Each outstanding warrant to purchase a Qell Class A Ordinary Share will, by its terms, convert into a warrant to purchase one Holdco Class A Share, on the same contractual terms.

Additionally, in connection with their entry into the Business Combination Agreement, Qell and Holdco entered into a letter agreement (the “Sponsor Letter Agreement”) with Qell Partners LLC (the “Sponsor”) and Lilium, pursuant to which the Sponsor has agreed (a) to vote in favor of the Business Combination Agreement and the transactions contemplated thereby and take all actions reasonably necessary to cause the closing of the Business Combination, including execution of the Holdco shareholder approval, (b) to waive any adjustment to the conversion ratio set forth in the Qell’s amended and restated memorandum and articles of association or any other anti-dilution or similar protection with respect to the Qell Class B Ordinary Shares of Qell held by them, and (c) forfeit 1,828,945 Qell Class B Ordinary Shares that would otherwise have converted into 1,828,945 Holdco Class A Shares in connection with the Merger for no consideration, and subject 3,063,422 of the Holdco Shares acquired by the Sponsor in connection with

TABLE OF CONTENTS

the Merger (in addition to any New Shares (as defined in the Sponsor Letter Agreement) issued with respect to such Holdco Shares) to certain time and performance vesting provisions.

The above matters are more fully described in this proxy statement/prospectus, which also includes, as Annex A, a copy of the Business Combination Agreement. You are urged to read carefully this proxy statement/prospectus in its entirety, including the Annexes and accompanying financial statements of Holdco, Qell and Lilium.

Pursuant to the Qell amended and restated memorandum and articles of association, Qell is providing its public shareholders with the opportunity to redeem, upon the closing of the Business Combination, Qell Class A Ordinary Shares then held by them for cash equal to their pro rata share of the aggregate amount on deposit (as of two business days prior to the closing of the Business Combination) in the Trust Account that holds the proceeds (including interest accrued thereon, which shall be net of taxes payable) of the Qell IPO and certain of the proceeds of the sale of the warrants to certain Qell shareholders in connection with Qell’s IPO (the “Private Placement Warrants”). Redemptions referred to herein shall take effect as repurchases under the Qell amended and restated memorandum and articles of association (the “Qell Shareholder Redemption”). The per-share amount Qell will distribute to investors who properly redeem their Qell Class A Ordinary Shares will not be reduced by the aggregate deferred underwriting commission of $13,282,500 that Qell will pay to the underwriters of the Qell IPO or transaction expenses incurred in connection with the Business Combination. For illustrative purposes, based on the fair value of marketable securities held in the Trust Account of approximately $ as of , 2021, the estimated per Qell Class A Ordinary Share redemption price would have been approximately $ . The redemption rights include the requirement that a holder must identify himself, herself or itself in writing as a beneficial holder and provide his, her or its legal name, phone number and address to the Transfer Agent in order to validly redeem his, her or its shares. Public shareholders may elect to redeem their shares even if they vote for the Business Combination Proposal. A public shareholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, in excess of 15% of the outstanding Qell Class A Ordinary Shares (i.e., in excess of 5,692,500 Qell Class A Ordinary Shares). Each redemption of Qell Class A Ordinary Shares by Qell’s public shareholders will reduce the amount in the Trust Account. The Business Combination Agreement provides that Lilium’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (after giving effect to the Qell Shareholder Redemption) together with the proceeds actually received from the PIPE Financing being at least $450,000,000. The committed PIPE subscriptions are sufficient to satisfy this condition if fully funded, even if existing Qell shareholders exercise their redemption rights.

The conditions to closing in the Business Combination Agreement are for the sole benefit of the parties thereto and may be waived by such parties. In no event will Qell redeem its Qell Class A Ordinary Shares in an amount that would cause its (or Holdco’s after giving effect to the Business Combination) net tangible assets to be less than $5,000,001, as provided in the Qell amended and restated memorandum and articles of association and as required as a closing condition to each party’s obligation to consummate the Business Combination under the terms of the Business Combination Agreement. Holders of outstanding Qell Public Warrants do not have redemption rights in connection with the Business Combination. Unless otherwise specified, the information in the accompanying proxy statement/prospectus assumes that (i) none of Qell’s public shareholders exercise their redemption rights with respect to their Qell Class A Ordinary Shares, and (ii) Participating Shareholders represent 100% of the issued and outstanding shares of Lilium and there are no “change of control” payments made or required to be made by Lilium. For more information about the factors that affect the assumptions above, please see the section entitled “The Business Combination — Ownership of Holdco.”

The Sponsor has agreed to waive its redemption rights with respect to any Qell Ordinary Shares it may hold in connection with the consummation of the Business Combination (the “Founder Shares”), and the Founder Shares will be excluded from the pro rata calculation used to determine the per-share redemption price. Currently, the Sponsor owns 20% of the issued and outstanding Qell Ordinary Shares, including all of the Founder Shares. The Sponsor has agreed to vote any Qell Ordinary Shares owned by it in favor of the Business Combination. The Founder Shares are subject to transfer restrictions. The Qell amended and restated

TABLE OF CONTENTS

memorandum and articles of association includes a conversion adjustment which provides that the Founder Shares will automatically convert at the time of the Business Combination into a number of Qell Class A Ordinary Shares one day after the closing of the transactions contemplated by the Business Combination Agreement, at a conversion rate that entitles the holders of such Founder Shares to continue to own, in the aggregate, 20% of the issued and outstanding Qell Ordinary Shares after giving effect to the PIPE Financing. However, the Sponsor has agreed to waive such conversion adjustment pursuant to the Sponsor Letter Agreement. As a result, each remaining Founder Share will be exchanged for one Holdco Share at the closing of the Business Combination, such that the Sponsor will hold approximately 2.3% (on a fully diluted basis) of the total number of Holdco Shares outstanding after the consummation of the Business Combination. Please see the section entitled “Frequently Used Terms and Basis of Presentation” in the proxy statement/prospectus for assumptions relating to this calculation.

The closing of the Business Combination is conditioned upon the approval of the Business Combination Proposal and the Merger Proposal. The Incentive Plan Proposal and the ESPP Proposal are conditioned upon the approval of the Business Combination Proposal and the Merger Proposal. The Adjournment Proposal is not conditioned on the approval of any other proposal set forth in this proxy statement/prospectus.

Approval of the Merger Proposal requires the affirmative vote of holders of at least two-thirds of the Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. Approval of the Business Combination Proposal, the Incentive Plan Proposal and the ESPP Proposal requires the affirmative vote of holders of a majority of the Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. The Qell Board recommends that you vote “FOR” each of these proposals.

ABOUT THIS PROXY STATEMENT/PROSPECTUS

This document, which forms part of a registration statement on Form F-4 filed with the U.S. Securities and Exchange Commission, or SEC, by Holdco (File No. 333-255800), constitutes a prospectus of Holdco under Section 5 of the U.S. Securities Act of 1933, as amended, or the Securities Act, with respect to the Holdco securities to be issued to Qell shareholders and Lilium shareholders, if the business combination described below is consummated. This document also constitutes a notice of meeting and a proxy statement under Section 14(a) of the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, with respect to the general meeting of Qell shareholders at which Qell shareholders will be asked to consider and vote upon proposals to adopt and approve the Business Combination Agreement and the transactions contemplated thereby, including the Business Combination, and to adopt and approve the Merger, along with the Merger Documents, including the Plan of Merger, by the approval and adoption of the Business Combination Proposal and the Merger Proposal, respectively, as well as to adopt and approve the Incentive Plan and the ESPP, by the approval and adoption of the Incentive Plan Proposal and the ESPP Proposal, respectively, among other matters.

CONVENTIONS WHICH APPLY TO THIS PROXY STATEMENT/PROSPECTUS

In this proxy statement/prospectus, unless otherwise specified or the context otherwise requires:

•

“$,” “USD” and “U.S. dollar” each refer to the United States dollar; and

•

“€,” “EUR” and “Euro” each refer to the Euro.

The exchange rate used for conversion between U.S. dollars and Euros is based on the ECB euro reference exchange rate published by the European Central Bank.

IMPORTANT INFORMATION ABOUT U.S. GAAP, IFRS AND NON-IFRS FINANCIAL MEASURES

Qell’s financial statements included in this proxy statement/ prospectus have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the SEC.

Lilium’s audited financial statements included in this proxy statement/prospectus have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). This proxy statement/prospectus includes certain references to financial measures that were not prepared in accordance with IFRS, including Adjusted EBITDA. The presentation of this non-IFRS information is not meant to be considered in isolation or as a substitute for Lilium’s consolidated financial results prepared in accordance with IFRS.

This proxy statement/prospectus also uses “contribution margin”, which is not a measurement of Lilium’s financial performance under IFRS and does not purport to be an alternative to gross profit or loss after tax derived in accordance with IFRS. Lilium’s management uses contribution margin to evaluate its future operating performance within its industry because:

•

it permits management to evaluate and analyze its productivity, efficiency and performance while taking into account demand generation expense as a measurement of operating performance;

•

it assists management in comparing Lilium’s operating performance on a consistent basis, as it removes the impact of items not directly resulting from Lilium’s core operations;

•

for planning purposes, including the preparation of Lilium’s internal annual operating budget and financial projections;

•

to evaluate the performance and effectiveness of Lilium’s strategic initiatives; and

•

to evaluate Lilium’s capacity to fund capital expenditures necessary to grow its business.

Lilium’s definition and calculation of “contribution margin” may not be comparable to similar measures disclosed by other companies, because not all companies and analysts calculate these measures in the same manner. Lilium presents contribution margin in this proxy statement/prospectus because it considers it to be an important supplemental measure of its future operating performance, and Lilium believes it is

TABLE OF CONTENTS

frequently used by securities analysts, investors and other interested parties in evaluating companies. Lilium’s management believes that investors’ understanding of Lilium’s performance will be enhanced by including contribution margin as a reasonable basis for comparing its proposed results of operations.

Items excluded from contribution margin are significant components in understanding and assessing financial performance. Contribution margin does not reflect Lilium’s capital expenditures, or future requirements for capital expenditures or contractual commitments, nor does it reflect changes in Lilium’s working capital needs. Lilium compensates for these limitations by relying primarily on its IFRS results and using contribution margin only as a supplemental measure. Non-IFRS measures such as contribution margin have limitations as analytical tools and should not be considered in isolation, or as an alternative to, or a substitute for loss after tax, revenue or other financial statement data presented in Lilium’s consolidated financial statements as indicators of financial performance. Other companies or analysts may calculate contribution margin differently than Lilium does, limiting its usefulness as a comparative measure.

For additional information, see the section entitled “General Information — Presentation of Financial Information.”

We plan to announce any such updates on our proxy website, and we encourage you to check this website prior to the meeting if you plan to attend.

Are the proposals conditioned on one another?

It is important for you to note that in the event the Business Combination Proposal and the Merger Proposal do not receive the requisite vote for approval, then Qell will not consummate the Business Combination. If Qell does not consummate the Business Combination and fails to complete an initial business combination by October 2, 2022, Qell will be required to dissolve and liquidate the Trust Account by returning the then remaining funds in such Trust Account to its public shareholders.

Why is Qell proposing the Business Combination?

Qell is a blank check company incorporated as a Cayman Islands exempted company on August 7, 2020, and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more target businesses. Although Qell may pursue an acquisition opportunity in any business, industry, sector or geographical location for purposes of consummating an initial business combination, Qell has focused on next-generation mobility, transportation and sustainable industrial technology sections. Qell is not permitted under its amended and restated memorandum and articles of association to effect a business combination with a blank check company or a similar type of company with nominal operations.

Qell has identified several criteria and guidelines it believes are important for evaluating acquisition opportunities. Qell has sought to acquire companies in the next-generation mobility, transportation or sustainable industrial technology sectors, that demonstrate significant growth potential and/or value creation opportunities for our shareholders, are complemented by our management team’s expertise and vision, and may demonstrate some of the following characteristics: (1) large addressable market, (2) high growth potential, (3) have differentiated and proprietary technology, (4) have an attractive business model, (5) present an opportunity for our operational, commercial and financial expertise to enhance value, (6) allows for a partnership approach with management and (7) have a desirable value proposition as a public company.

Based on its due diligence investigations of Lilium and the industry in which it operates, including the financial and other information provided by Lilium in the course of negotiations, Qell believes that Lilium meets the criteria and guidelines listed above. Please see the section entitled “The Business Combination — The Qell Board’s Reasons for the Business Combination” for additional information.

TABLE OF CONTENTS

Why is Qell providing shareholders with the opportunity to vote on the Business Combination?

The approval of the Business Combination is required under the Qell amended and restated memorandum and articles of association, and the Merger requires the approval of Qell shareholders under Cayman Islands law. In addition, such approvals are also conditions to the closing of the Business Combination under the Business Combination Agreement. Additionally, under its amended and restated memorandum and articles of association, Qell must provide all holders of public shares with the opportunity to have their public shares redeemed upon the consummation of its initial business combination either in conjunction with a tender offer or in conjunction with a shareholder vote. For business and other reasons, Qell has elected to provide its shareholders with the opportunity to have their public shares redeemed in connection with a shareholder vote rather than a tender offer. The redemption rights include the requirement that a holder must identify itself in writing as a beneficial holder and provide its legal name, phone number and address to the Transfer Agent in order to validly redeem its shares. Therefore, Qell is seeking to obtain the approval of its shareholders of the Business Combination and also allow its public shareholders to effectuate redemptions of their public shares in connection with the closing of the Business Combination in accordance with the Qell amended and restated memorandum and articles of association.

What other matters will be brought before the General Meeting?

In addition to consideration of the proposals described above, Qell shareholders will have the opportunity to consider the financial statements of Qell for the year ended December 31, 2020 and ask questions of Qell’s management.

What revenues and profits/losses has Lilium generated in the last two years?

For the fiscal years ended December 31, 2020 and 2019, Lilium had revenues of €97 thousand and €0, and net losses of €188,427 thousand and €63,479 thousand, respectively. At the end of fiscal year 2020, Lilium’s total assets were €184,946 thousand and its total liabilities were €127,224 thousand. For additional information, please see Lilium’s audited consolidated financial statements for the years ended December 31, 2020 and 2019 included elsewhere in this proxy statement/prospectus.

What impact will the COVID-19 pandemic have on the Business Combination?

Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the impact of the COVID-19 outbreak on the business of Qell, Lilium and Holdco, and there is no guarantee that efforts by Qell, Lilium and Holdco to address the adverse impacts of COVID-19 will be effective. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19 and actions taken to contain COVID-19 or its impact, among others. If Qell or Lilium are unable to recover from a business disruption on a timely basis, the Business Combination and Holdco’s business, financial condition and results of operations following the completion of the Business Combination would be adversely affected. The Business Combination may also be delayed and adversely affected by COVID-19 outbreak and become more costly. Each of Qell, Lilium and Holdco may also incur additional costs to remedy damages caused by any such disruptions, which could adversely affect its financial condition and results of operations.

What will happen in the Business Combination?

Pursuant to the Business Combination Agreement, and upon the terms and subject to the conditions set forth therein, Qell and Lilium will effect a transaction that would replicate the economics of a merger of Qell and Lilium through a series of mergers and equity contributions and exchanges, which is collectively referred to as the Business Combination. To effect the Business Combination, among other things, (i) the Merger will be effected; (ii) the Liquidation Distribution and Assumption will be effected; and (iii) the Exchange will be effected. As a result of the Business Combination, Holdco will be the ultimate parent company of Lilium (following the Exchange) and Lilium’s direct and indirect subsidiaries. Please see the section entitled “The Business Combination” for additional information.

Holdco intends to apply to list the Holdco Class A Shares and Holdco Public Warrants on the Nasdaq under the symbols “LILM” and “LILMW,” respectively, upon the closing of the Business Combination.

TABLE OF CONTENTS

We cannot assure you that the Holdco Class A Shares or Holdco Public Warrants will be approved for listing on Nasdaq. In addition, Holdco will be a “foreign private issuer” and as a “foreign private issuer,” Holdco will be subject to different U.S. securities laws than domestic U.S. issuers. The rules governing the information that Holdco must disclose differ from those governing U.S. corporations pursuant to the Exchange Act. Holdco will be exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders. As a foreign private issuer, Holdco will be exempt from a number of rules under the U.S. securities laws and will be permitted to file less information with the SEC than a U.S. company. This may limit the information available to holders of the Holdco Shares and Holdco Public Warrants. See “Risk Factors — As a foreign private issuer, we will be exempt from a number of rules under the U.S. securities laws and will be permitted to file less information with the SEC than a U.S. domestic public company, which may limit the information available to our shareholders.”

How has the announcement of the Business Combination affected the trading price of Qell’s Class A Ordinary Shares?

On March 29, 2021, the last trading date before the public announcement of the Business Combination, the Qell Public Units, Qell Class A Ordinary Shares and Qell Public Warrants closed at $10.39, $9.92 and $1.52, respectively. On , 2021, the trading date immediately prior to the date of this proxy statement/prospectus, the Qell Public Units, Qell Class A Ordinary Shares and Qell Public Warrants closed at $ , $ and $ , respectively.

Following the Business Combination, will Qell’s securities continue to trade on a stock exchange?

No. Qell anticipates that, following consummation of the Business Combination, the Qell Class A Ordinary Shares, Qell Public Units, and Qell Public Warrants will be delisted from Nasdaq and Qell will be deregistered under the Exchange Act. However, Holdco intends to apply to list the Holdco Class A Shares and Holdco Public Warrants on Nasdaq under the symbols “LILM” and “LILMW,” respectively, upon the closing of the Business Combination.

Is the Business Combination the first step in a “going private” transaction?

No. Qell does not intend for the Business Combination to be the first step in a “going private” transaction. One of the primary purposes of the Business Combination is to provide a platform for Lilium to access the U.S. public markets.

Will the management of Lilium change in the Business Combination?

The current executive officers of Lilium are Daniel Wiegand, the Chief Executive Officer and Geoffrey Richardson, the Chief Financial Officer. These individuals are intended to continue to serve as Holdco’s executive officers upon consummation of the Business Combination.

Pursuant to the Business Combination Agreement, effective immediately upon closing, the Holdco Board will be comprised of seven directors, with each director serving a one-year term, other than Barry Engle, who shall serve a three-year term.

Upon the closing of the Business Combination, the Holdco Board is intended to comprise seven directors, consisting of the following:

•

(1) Thomas Enders; (2) Barry Engle; (3) Daniel Wiegand; (4) David Wallerstein; (5) Niklas Zennström and two additional directors who will be designated by Lilium prior to the closing of the Business Combination;

•

The management team will consist solely of Lilium’s current management team immediately prior to the Closing, including individuals selected by Lilium that join its management team between the date hereof and the closing; and

•

Daniel Wiegand will be granted special governance provisions, including a dual class structure with super-voting (i.e., 3:1) shares, subject to customary sunset provisions.

For an explanation of the roles and responsibilities of the Holdco Board, please see the section entitled “Management of Holdco After the Business Combination”.

TABLE OF CONTENTS

What will Qell shareholders receive in the Business Combination?

Upon consummation of the Merger, each issued and outstanding Qell Ordinary Share will be subject to the terms and conditions of the Business Combination Agreement and the Plan of Merger and will be converted into a claim for a corresponding equity security in the Merger Sub and such claim shall then be contributed into Holdco in exchange for a Holdco Class A Share.

What will Qell warrant holders receive in the Business Combination?

As a result of the Merger and without any action of any Party or any other Person (but without limiting the obligations of Holdco pursuant to the Business Combination Agreement), each Qell Warrant that is outstanding immediately prior to the Merger Effective Time shall automatically cease to represent a right to acquire Qell Class A Ordinary Shares and shall automatically represent, immediately following the Merger Effective Time, a right to acquire Holdco Class A Shares on the same contractual terms and conditions as were in effect immediately prior to the Merger Effective Time under the terms of the Warrant Agreement; provided, that each converted warrant: (a) shall represent the right to acquire the number of Holdco Class A Shares equal to the number of Qell Class A Ordinary Shares subject to each such Qell Public Warrant immediately prior to the Merger Effective Time; (b) shall have an exercise price of $11.50 per whole warrant required to purchase one Holdco Class A Share; and (c) shall expire on the five (5) year anniversary of the Final Closing Date.

What will Qell unit holders receive in the Business Combination?

In connection with the consummation of the Business Combination, the Qell Public Units will automatically separate into their component parts and be treated accordingly.

What will Lilium Shareholders receive in the Business Combination?

Upon consummation of the Exchange, holders of Lilium ordinary shares will receive Holdco Class A Shares, except for Daniel Wiegand or any of his Affiliates who will receive Holdco Class B Shares. See “Summary — Consideration to Lilium Shareholders in the Business Combination” for information on the consideration to be received by Lilium shareholders, including the assumptions on which this calculation is based.

What are the differences between the Holdco Class A Shares and the Holdco Class B Shares, and what will be the voting percentages of the different shareholders?

Holdco Class B Shares will rank pari passu with Holdco Class A Shares in all respects, provided they will be entitled to 3x super voting rights, subject to customary sunset provisions. It is anticipated that, upon completion of the Business Combination: (i) Qell’s public shareholders will receive approximately 12% of Holdco Shares and 11% of the voting rights; (ii) the PIPE Investors will receive approximately 15% of Holdco Shares and 12% of the voting rights; (iii) the Sponsor will receive approximately 2% of Holdco Shares and 2% of the voting rights; and (iv) the Participating Shareholders will receive approximately 71% of Holdco Shares and 75% of the voting rights. These ownership levels in Holdco assume the following: (i) no redemptions by the public shareholders, (ii) that the amount in the Trust Account is $379,600,000 (which was the approximate value of the Trust Account as of December 31, 2020, not taking into account $13,282,500 of deferred underwriting fees to be paid), (iii) Participating Shareholders represent 100% of the issued and outstanding shares of Lilium and there are no “change of control” payments made or required to be made by Lilium, and (iv) that PIPE Investors fund the PIPE Financing in full in accordance with the Subscription Agreements.

What is the PIPE Financing?

In connection with the Business Combination and concurrently with the execution of the Business Combination Agreement, Qell and Holdco entered into the Subscription Agreements with the PIPE Investors pursuant to which the PIPE Investors agreed to subscribe for and purchase, and Holdco agreed to issue and sell to such PIPE Investors, an aggregate number of Holdco Shares set forth in the Subscription Agreements in exchange for an aggregate purchase price of $450,000,000.

TABLE OF CONTENTS

What equity stake will the current shareholders of Qell, the PIPE Investors and the current shareholders of Lilium hold in Holdco after the closing of the Business Combination?

It is anticipated that, upon completion of the Business Combination: (i) Qell’s public shareholders (other than the PIPE Investors) will receive approximately 11.4% of Holdco Shares on a fully diluted basis; (ii) the PIPE Investors (some of whom are also Lilium equityholders) will receive approximately 13.6% shares of Holdco on a fully diluted basis; (iii) the Qell Initial Shareholders (including the Sponsor) will receive approximately 2.3% of Holdco Shares on a fully diluted basis; and (iv) the former Lilium equityholders (excluding any Holdco Shares issued pursuant to the PIPE Financing) will receive approximately 65.9% of Holdco Shares on a fully diluted basis. These levels of ownership assume (A) no Qell Class A Ordinary Shares are elected to be redeemed by Qell’s public shareholders, (B) that 45,000,000 Holdco Shares are issued to the PIPE Investors in connection with the PIPE Financing, and (C) Participating Shareholders represent 100% of the issued and outstanding shares of Lilium and there are no “change of control” payments made or required to be made by Lilium.

The ownership percentages with respect to Holdco following the Business Combination do not take into account any awards to be issued under the ESPP or the Incentive Plan or the Private Placement Warrants or the Holdco Public Warrants, but do include Founder Shares, which will be exchanged for Holdco Class A Shares at the closing of the Business Combination on a one-for-one basis. If the actual facts are different than these assumptions, the ownership percentages in Holdco will be different.

For more information, please see the sections entitled “The Business Combination — Ownership of Holdco” and “Unaudited Pro Forma Condensed Combined Financial Information.”

Will Qell obtain new financing in connection with the Business Combination and are there any arrangements to help ensure that Qell will have sufficient funds to consummate the Business Combination?

Yes. Qell will obtain new equity financing through a private placement of Holdco Shares in the PIPE Financing. Holdco will use the Aggregate PIPE Proceeds, together with the proceeds received from the Trust Account, for general corporate purposes. The PIPE Financing is contingent upon, among other things, the closing of the Business Combination. Unless waived by Qell or Lilium, the Business Combination Agreement provides that each party’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (net of any amounts redeemed) together with the Aggregate PIPE Proceeds equaling or exceeding $450,000,000.

Why is Qell proposing the Incentive Plan Proposal?

Qell is proposing the Incentive Plan Proposal to promote ownership in Lilium by its employees, non-employee directors and consultants, and align incentives between these service providers and shareholders by permitting these service providers to receive compensation in the form of awards denominated in, or based on the value of, our shares. The Incentive Plan Proposal is conditioned on the approval of the Business Combination Proposal and the Merger Proposal. If both the Business Combination Proposal and the Merger Proposal are not approved, the Incentive Plan Proposal will have no effect, even if approved by our shareholders. Please see the section entitled “Proposal No. 3 — The Incentive Plan Proposal” for additional information.

Q: Why is Qell proposing the ESPP Proposal?

Qell is proposing the ESPP Proposal, which permits eligible employees and/or service providers the opportunity to purchase shares of Holdco Class A Shares, to promote employee retention and incentives for such persons to exert maximum efforts for the success of the company and its affiliates. The ESPP Proposal is conditioned on the approval of the Business Combination Proposal and the Merger Proposal. If both the Business Combination Proposal and the Merger Proposal are not approved, the ESPP Proposal will have no effect, even if approved by our shareholders. Please see the section entitled “Proposal No. 4 — The Employee Share Purchase Proposal” for additional information.

TABLE OF CONTENTS

Why is Qell proposing the Adjournment Proposal?

Qell is proposing the Adjournment Proposal to allow the Qell Board to adjourn the General Meeting to a later date or dates, (A) in order to solicit additional proxies from Qell shareholders in favor of the Business Combination Proposal or the Merger Proposal, (B) if as of the time for which the General Meeting is scheduled, there are insufficient Qell Ordinary Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct business at the General Meeting, or (C) to allow reasonable time for the filing or mailing of any supplemental or amended disclosures that Qell has determined, based on the advice of outside legal counsel, is reasonably likely to be required under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by Qell shareholders prior to the General Meeting. The Adjournment Proposal will only be presented to Qell shareholders in the event that there are insufficient votes for, or otherwise in connection with, the approval of the Business Combination Proposal or the Merger Proposal. Please see the section entitled “Proposal No. 5 — The Adjournment Proposal” for additional information.

What happens if I sell my Qell Ordinary Shares before the General Meeting?

The record date for the General Meeting for Qell shareholders that hold their shares in “street name” is earlier than the date that the Business Combination is expected to be completed. If you transfer your Qell Ordinary Shares after the record date for Qell shareholders that hold their shares in “street name,” but before the General Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the General Meeting. However, you will not be able to seek redemption of your Qell Class A Ordinary Shares because you will no longer be able to deliver them for cancellation upon consummation of the Business Combination. If you transfer your Qell Ordinary Shares prior to the record date for Qell shareholders that hold their shares in “street name,” you will have no right to vote those shares at the General Meeting or redeem those shares for a pro rata portion of the proceeds held in the Trust Account.

What vote is required to approve the proposals presented at the General Meeting?

The approval of the Business Combination Proposal requires the affirmative vote of holders of at least a majority of Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting, and the approval of the Merger Proposal requires the affirmative vote of holders of at least two-thirds of the Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Business Combination Proposal or the Merger Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Business Combination Proposal or the Merger Proposal. The Sponsor has agreed to vote their Founder Shares and any public shares purchased by them during or after the Qell IPO in favor of the Business Combination Proposal.

The approval of the Incentive Plan Proposal requires the affirmative vote of holders of at least a majority of Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Incentive Plan Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Incentive Plan Proposal. The Incentive Plan Proposal is conditioned upon the approval of the Business Combination Proposal and the Merger Proposal. If both the Business Combination Proposal and the Merger Proposal are not approved, the Incentive Plan Proposal will have no effect, even if approved by our shareholders.

The approval of the ESPP Proposal requires the affirmative vote of holders of at least a majority of Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted

towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the ESPP Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the ESPP Proposal. The ESPP Proposal is conditioned upon the approval of the Business Combination Proposal and the Merger Proposal. If both the Business Combination Proposal and the Merger Proposal are not approved, the ESPP Proposal will have no effect, even if approved by our shareholders.

The approval of the Adjournment Proposal requires the affirmative vote of holders of a majority of the Qell Ordinary Shares that are entitled to vote and are voted at the General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Adjournment Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Adjournment Proposal

Q: What happens if the Business Combination Proposal or the Merger Proposal are not approved?

If the Business Combination Proposal or the Merger Proposal are not approved and Qell does not consummate a business combination by October 2, 2022, Qell will be required to dissolve and liquidate the Trust Account.

What happens if the Incentive Plan Proposal or the ESPP Proposal are not approved?

If the Incentive Plan Proposal is not approved, the Incentive Plan will not be adopted. If the ESPP Proposal is not approved, the ESPP will not be adopted.

How many votes do I have at the General Meeting?

Qell shareholders that hold their shares in “street name” are entitled to one vote on each proposal presented at the General Meeting for each Qell Ordinary Share held of record as of , 2021, the record date for the General Meeting. As of the close of business on the record date, there were outstanding Qell Ordinary Shares. For the avoidance of doubt, the record date does not apply to Qell shareholders that hold their shares in registered form and are registered as shareholders in Qell’s register of members. Qell shareholders that hold their shares in registered form are entitled to one vote on each proposal presented at the General Meeting for each Qell Ordinary Share held on the date of the General Meeting.

What constitutes a quorum at the General Meeting?

One or more shareholders who together hold 50% of the issued and outstanding Qell Ordinary Shares entitled to vote at the General Meeting must be present, in person or represented by proxy, at the General Meeting to constitute a quorum and in order to conduct business at the General Meeting. Broker non-votes and abstentions will be counted as present for the purpose of determining a quorum. The Sponsor, who currently owns 20% of the issued and outstanding Qell Ordinary Shares, will count towards this quorum. In the absence of a quorum, the chairman of the General Meeting has power to adjourn the General Meeting. As of the record date for the General Meeting for Qell shareholders that hold their shares in “street name,” the presence of Qell Ordinary Shares would be required to achieve a quorum.

How will the Qell Initial Shareholders and Qell’s other current directors and officers vote?

Prior to the Qell IPO, Qell entered into agreements with the Sponsor, pursuant to which it has agreed to vote any Qell Ordinary Shares owned by the Sponsor in favor of a proposed initial business combination. As of the record date, the Sponsor owned Founder Shares, representing % of the Qell Ordinary Shares and entitled to vote at the General Meeting.

TABLE OF CONTENTS

What interests do the Sponsor, Qell Initial Shareholders and Qell’s other current officers and directors have in the Business Combination?

The Sponsor, Qell Initial Shareholders and Qell’s other current officers and directors have interests in the Business Combination that are different from or in addition to (and which may conflict with) your interests. You should take these interests into account in deciding whether to approve the Business Combination Proposal and the Merger Proposal. These interests include:

•

the fact that the Sponsor has agreed not to redeem any Qell Ordinary Shares held by it in connection with a shareholder vote to approve a proposed initial business combination;

•

the fact that Sponsor paid an aggregate of $25,000 for the Founder Shares and such securities will have a significantly higher value at the time of the Business Combination which, if unrestricted and freely tradable, would be valued at approximately $76,585,550, taking into account the 1,828,945 Founder Shares that Sponsor has agreed to forfeit in connection with the Business Combination, but, given the transfer restrictions on such shares, Qell believes such shares have less value;

•

the fact that the Sponsor paid an aggregate of $10,590,000 for its 7,060,000 Private Placement Warrants (these have an aggregate fair market value of $12,143,200 as of March 31, 2021) and that such Private Placement Warrants will expire worthless if a business combination is not consummated by October 2, 2022;

•

the fact that the Qell Initial Shareholders and Qell’s other current officers and directors have agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if Qell fails to complete an initial business combination by October 2, 2022;

•

the fact that the Registration Rights Agreement will be entered into by the Sponsor;

•

the fact that, at the option of Sponsor, any amounts outstanding under certain working capital loans made by Sponsor or any of its affiliates to Qell (currently $400,000 remains outstanding) in an aggregate amount of up to $1,500,000 may be converted into warrants to purchase Qell Class A Ordinary Shares which will be identical to the Private Placement Warrant;

•

the right of the Sponsor to receive Holdco Shares, subject to certain lock-up periods;

•

the continued indemnification of Qell’s existing directors and officers and the continuation of Qell’s directors’ and officers’ liability insurance after the Business Combination;

•

the fact that Sponsor and Qell’s officers and directors will lose their entire investment in Qell and will not be reimbursed for any out-of-pocket expenses if an initial business combination is not consummated by October 2, 2022; and

•

the fact that if the Trust Account is liquidated, including in the event Qell is unable to complete an initial business combination within the required time period, the Sponsor has agreed to indemnify Qell to ensure that the proceeds in the Trust Account are not reduced below $10.00 per public share, or such lesser per public share amount as is in the Trust Account on the liquidation date, by the claims of prospective target businesses with which Qell has entered into an acquisition agreement or claims of any third party for services rendered or products sold to Qell, but only if such a vendor or target business has not executed a waiver of any and all rights to seek access to the Trust Account.

Did the Qell Board obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

No. The Qell Board did not obtain a third-party valuation or fairness opinion in connection with its determination to approve the Business Combination. Qell’s officers and directors have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and backgrounds, together with the experience and sector expertise of Qell’s advisors, enabled them to make the necessary analyses and determinations regarding the Business Combination. In addition, Qell’s officers and directors and its advisors have substantial experience with mergers and acquisitions. Accordingly, investors will be relying solely on the judgment of the Qell Board in valuing Lilium’s business and assuming the risk that the Qell Board may not have properly valued such business. Furthermore, the Qell Board did not obtain a third-party valuation or

TABLE OF CONTENTS

fairness opinion in connection with the determination to approve the Business Combination but believed that the active negotiations with the PIPE participants and subsequent change to the size and structure of the offering served as validation of the appropriateness of the valuation and structure of the Business Combination.

What happens if I vote against the Business Combination Proposal or the Merger Proposal?

If you vote against the Business Combination Proposal or the Merger Proposal but the Business Combination Proposal and the Merger Proposal still obtain the affirmative vote of holders of at least the majority of Qell Ordinary Shares with respect to the Business Combination Proposal or two-thirds of Qell Ordinary Shares with respect to the Merger Proposal, that are entitled to vote and are voted at the General Meeting, then the Business Combination Proposal and the Merger Proposal will be approved, respectively, and, assuming the satisfaction or waiver of the other conditions to closing, the Business Combination will be consummated in accordance with the terms of the Business Combination Agreement.

If you vote against the Business Combination Proposal or the Merger Proposal and the Business Combination Proposal or the Merger Proposal do not obtain the affirmative vote of holders of the majority of Qell Ordinary Shares with respect to the Business Combination Proposal or two-thirds of Qell Ordinary Shares with respect to the Merger Proposal, that are entitled to vote and are voted at the General Meeting, then the Business Combination Proposal and the Merger Proposal, respectively, will fail and Qell will not consummate the Business Combination. If Qell does not consummate the Business Combination, it may continue to try to complete a business combination with a different target business until October 2, 2022. If Qell fails to complete an initial business combination by October 2, 2022, then it will be required to dissolve and liquidate the Trust Account by returning the then-remaining funds in such account to its public shareholders.

Do I have redemption rights?

Pursuant to Qell’s amended and restated memorandum and articles of association, holders of Qell public shares may elect to have their shares redeemed for cash at the applicable redemption price per share calculated in accordance with Qell’s amended and restated memorandum and articles of association. As of , 2021, this would have amounted to approximately $ per share. If a holder of Qell public shares exercises its redemption rights, then such holder will be exchanging its Qell Class A Ordinary Shares for cash and will not own shares of Holdco following the closing of the Business Combination. Such a holder will be entitled to receive cash for its public shares only if it properly demands redemption and delivers its shares (either physically or electronically) to the Transfer Agent in accordance with the procedures described herein. The redemption rights include the requirement that a holder must identify itself in writing as a beneficial holder and provide its legal name, phone number and address to the Transfer Agent in order to validly redeem its shares. Notwithstanding the foregoing, a holder of the public shares, together with any affiliate of his or her or any other person with whom he or she is acting in concert or as a “group” (as defined in Section 13 of the Exchange Act) will be restricted from seeking redemption rights with respect to more than fifteen percent (15%) of the Qell Class A Ordinary Shares included in the Qell Public Units sold in the Qell IPO. Accordingly, all public shares in excess of the 15% threshold beneficially owned by a public shareholder or group will not be redeemed for cash.

Qell has no specified maximum redemption threshold under its amended and restated memorandum and articles of association, other than the aforementioned 15% threshold. Each redemption of Qell Class A Ordinary Shares by Qell public shareholders will reduce the amount in the Trust Account, which held marketable securities with a fair value of approximately $ as of , 2021. The Business Combination Agreement provides that Lilium’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (after giving effect to the Qell Shareholder Redemption) together with the proceeds actually received from the PIPE Financing being at least $450,000,000. The committed PIPE subscriptions are sufficient to satisfy this condition if fully funded, even if existing Qell shareholders exercise their redemption rights. The conditions to closing in the Business Combination Agreement are for the sole benefit of the parties thereto and may be waived by such parties. In no event will Qell redeem its Qell Class A Ordinary Shares in an amount that would cause its (or Holdco’s after giving effect to the transactions contemplated by the Business Combination

Agreement) net tangible assets to be less than $5,000,001, as provided in the Qell amended and restated memorandum and articles of association and as required as a closing condition to each party’s obligation to consummate the Business Combination under the terms of the Business Combination Agreement. Qell shareholders who wish to redeem their public shares for cash must refer to and follow the procedures set forth in the section entitled “General Meeting of Qell Shareholders — Redemption Rights” in order to properly redeem their public shares.

Holders of Qell Public Warrants will not have redemption rights with respect to such warrants.

Can the Sponsor redeem its Founder Shares in connection with consummation of the Business Combination?

No. The Sponsor has agreed to waive its redemption rights with respect to its Founder Shares and any public shares it may hold in connection with the consummation of the Business Combination.

Is there a limit on the number of shares I may redeem?

Yes. A public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), may not redeem Qell Class A Ordinary Shares in excess of an aggregate of 15% of the shares sold in the Qell IPO without Qell’s consent. Accordingly, all Qell Class A Ordinary Shares in excess of 15% of Qell Class A Ordinary Shares sold in the Qell IPO owned by a holder will not be redeemed for cash without Qell’s consent. On the other hand, a public shareholder who holds less than 15% of the public shares may redeem all of the public shares held by such shareholder for cash.

Qell Class B Ordinary Shares cannot be redeemed.

In no event is your ability to vote all of your shares (including those shares held by you in excess of 15% of the shares sold in the Qell IPO) for or against the Business Combination restricted.

Qell has no specified maximum redemption threshold under its amended and restated memorandum and articles of association, other than the aforementioned 15% threshold. Each redemption of Qell Class A Ordinary Shares by Qell public shareholders will reduce the amount in the Trust Account, which held marketable securities with a fair value of approximately $ as of , 2021. The Business Combination Agreement provides that each party’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (net of any amounts redeemed) together with the Aggregate PIPE Proceeds being at least $450,000,000. The committed PIPE subscriptions are sufficient to satisfy this condition if fully funded, even if existing Qell shareholders exercise their redemption rights. The conditions to closing in the Business Combination Agreement are for the sole benefit of the parties thereto and may be waived by such parties. In addition, in no event will Qell redeem its Qell Class A Ordinary Shares in an amount that would cause its (or Holdco’s after giving effect to the transactions contemplated by the Business Combination Agreement) net tangible assets to be less than $5,000,001, as provided in the Qell amended and restated memorandum and articles of association and as required as a closing condition to each party’s obligation to consummate the Business Combination under the terms of the Business Combination Agreement.

Is there a limit on the total number of Qell public shares that may be redeemed?

Yes. The Qell amended and restated memorandum and articles of association provide that it may not redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001 (such that Qell is not subject to the SEC’s “penny stock” rules). Other than this limitation and the aforementioned 15% threshold, the Qell amended and restated memorandum and articles of association does not provide a specified maximum redemption threshold. The Business Combination Agreement provides that, as a condition to each party’s obligation to consummate the Business Combination, Holdco may not have net tangible assets less than $5,000,001 at the Closing Commencement Date (after giving effect to the transactions contemplated by the Business Combination Agreement). In addition, the Business Combination Agreement provides that each party’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account together with the proceeds actually received from the PIPE Financing being at least $450,000,000. The committed PIPE subscriptions are sufficient to satisfy this condition if fully funded, even if existing Qell shareholders

exercise their redemption rights. If the Business Combination is not consummated, Qell will not redeem any Qell Class A Ordinary Shares and all Qell Class A Ordinary Shares submitted for redemption will be returned to the holders thereof, and Qell instead may search for an alternate business combination.

Will how I vote affect my ability to exercise redemption rights?

No. You may exercise your redemption rights whether you vote your Qell Class A Ordinary Shares for or against, or whether you abstain from voting on, the Business Combination Proposal, the Merger Proposal or any other proposal described by this proxy statement/prospectus. As a result, the Business Combination Agreement and the Plan of Merger can be approved by shareholders who will redeem their shares and no longer remain shareholders, leaving shareholders who choose not to redeem their shares holding shares in a company with a potentially less-liquid trading market, fewer shareholders, potentially less cash and the potential inability to meet the listing standards of Nasdaq.

How do I exercise my redemption rights?

In order to exercise your redemption rights, you must (i) if you hold Qell Public Units, separate the underlying Qell Class A Ordinary Shares and Qell Public Warrants, and (ii) prior to , New York City time, on , 2021 (two business days before the initial date of the General Meeting), tender your shares physically or electronically and identify yourself in writing as a beneficial holder and provide your legal name, phone number and address to the Transfer Agent in order to validly redeem your shares and submit a request in writing that Qell redeem your Qell Class A Ordinary Shares for cash to Continental Stock Transfer & Trust Company (the “Transfer Agent”) at the following address:

Continental Stock Transfer & Trust Company
1 State Street
New York, New York 10004
Attention:
Email:

You do not have to be a record date holder in order to exercise your redemption rights. Qell shareholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from the Transfer Agent and time to effect delivery. It is Qell’s understanding that Qell shareholders should generally allot at least two weeks to obtain physical certificates from the Transfer Agent. However, Qell does not have any control over this process and it may take longer than two weeks. Qell shareholders who hold their shares in “street name” will have to coordinate with their bank, broker or other nominee to have the shares certificated or delivered electronically.

Qell shareholders seeking to exercise their redemption rights, whether they are registered holders or hold their shares in “street name” are required to either tender their certificates to the Transfer Agent prior to the date set forth in this proxy statement/prospectus, or up to two business days prior to the vote on the Business Combination Proposal at the General Meeting, or to deliver their shares to the Transfer Agent electronically using Depository Trust Company’s (DTC) Deposit/Withdrawal At Custodian (DWAC) system, at such shareholder’s option. The requirement for physical or electronic delivery prior to the General Meeting ensures that a redeeming shareholder’s election to redeem is irrevocable once the Business Combination is approved.

Any demand for redemption, once made, may be withdrawn at any time until the vote is taken with respect to the Business Combination. If you delivered your shares for redemption to the Transfer Agent and decide within the required timeframe not to exercise your redemption rights, you may request that the Transfer Agent return the shares (physically or electronically). The redemption rights include the requirement that a holder must identify himself, herself or itself in writing as a beneficial holder and provide his, her or its legal name, phone number and address to the Transfer Agent in order to validly redeem his, her or its shares. You may make such request by contacting the Transfer Agent at the phone number or address listed under the question “Who can help answer my questions?” below.

If you hold Qell Public Units registered in your own name, you must deliver the certificate for such Qell Public Units to the Transfer Agent with written instructions to separate such Qell Public Units into Qell

TABLE OF CONTENTS

Class A Ordinary Shares and Qell Public Warrants. This must be completed far enough in advance to permit the mailing of the public share certificates back to you so that you may then exercise your redemption rights upon the separation of the public shares from the Qell Public Units.

If a broker, dealer, commercial bank, trust company or other nominee holds your Qell Public Units, you must instruct such nominee to separate your Qell Public Units. Your nominee must send written instructions by facsimile to the Transfer Agent. Such written instructions must include the number of Qell Public Units to be split and the nominee holding such Qell Public Units. Your nominee must also initiate electronically, using DTC’s DWAC system, a withdrawal of the relevant units and a deposit of an equal number of Qell Class A Ordinary Shares and Qell Public Warrants. This must be completed far enough in advance to permit your nominee to exercise your redemption rights upon the separation of the public shares from the Qell Public Units. While this is typically done electronically on the same business day, you should allow at least one full business day to accomplish the separation. If you fail to cause your Qell Public Units to be separated in a timely manner, you will likely not be able to exercise your redemption rights.

There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The Transfer Agent will typically charge a tendering broker a fee and it is in the broker’s discretion whether or not to pass this cost on to the redeeming shareholder. However, this fee would be incurred regardless of whether or not shareholders seeking to exercise redemption rights are required to tender their shares, as the need to deliver shares is a requirement to exercising redemption rights, regardless of the timing of when such delivery must be effectuated.

What are the U.S. federal income tax consequences of exercising my redemption rights?

The U.S. federal income tax consequences of exercising your redemption rights depend on your particular facts and circumstances. See the section entitled “Material Tax Considerations — Material U.S. Federal Income Tax Considerations — Tax Consequences for U.S. Holders Exercising Redemption Rights”. If you are a U.S. Holder of Qell Class A Ordinary Shares contemplating exercise of your redemption rights, you are urged to consult your tax advisor to determine the tax consequences thereof.

What are the U.S. federal income tax consequences to me of the Merger?

Subject to the limitations and qualifications described in “Material Tax Considerations — Material U.S. Federal Income Tax Considerations” below, the Merger will constitute a reorganization under Section 368(a)(1)(F) of the Code. As a result, you will generally not recognize gain or loss for U.S. federal income tax purposes on the receipt of Holdco Class A Shares for Qell Class A Ordinary Shares and Holdco Public Warrants for Qell Public Warrants in connection with the Merger.

If I am a Qell warrant holder, can I exercise redemption rights with respect to my Qell Public Warrants?

No. The holders of Qell Public Warrants have no redemption rights with respect to such warrants.

Do I have appraisal rights or dissenters’ rights if I object to the proposed Business Combination?

The Cayman Islands Companies Act provides that a shareholder of a Cayman company shall be entitled to payment of the fair value of that person’s shares upon dissenting from a merger or consolidation (the “Dissenter Rights”). However, such rights are not available in respect of the shares of any class for which an open market exists on a recognized stock exchange where, upon the merger or the consolidation, the shareholder receives, amongst other things, either: (a) shares of a surviving or consolidated company, or depository receipts in respect thereof; or (b) shares of any other company, or depository receipts in respect thereof, which shares or depository receipts at the effective date of the merger or consolidation, are either listed on a national securities exchange or designated as a national market system security on a recognized interdealer quotation system or held of record by more than two thousand holders.

With respect to the Merger, (i) Nasdaq is a recognized stock exchange and is a national securities exchange, (ii) Qell shareholders will be entitled to receive shares of the surviving company and (iii) such claim will be contributed immediately to Holdco in exchange for Holdco Shares that will be listed on Nasdaq. Accordingly, Dissenter Rights will not be available in respect of the Merger. The absence of

TABLE OF CONTENTS

Dissenter Rights does not impede a shareholder’s ability to exercise such shareholder’s redemption rights as outlined in the Qell amended and restated memorandum and articles of association.

Appraisal rights are not available to holders of Lilium shares in connection with the Business Combination.

What happens to the funds held in the Trust Account upon consummation of the Business Combination?

If the Business Combination is consummated, the funds held in the Trust Account will be used to: (i) pay Qell public shareholders who properly exercise their redemption rights; (ii) pay $13,282,500 in deferred underwriting commissions to the underwriters of the Qell IPO; and (iii) pay certain other fees, costs and expenses (including regulatory fees, legal fees, accounting fees, printer fees and other professional fees) that were incurred by Qell and other parties to the Business Combination Agreement in connection with the Business Combination pursuant to the terms of the Business Combination Agreement. Any remaining funds will be used by Holdco for general corporate purposes, and thereafter, the Trust Account shall terminate except as otherwise provided therein.

What conditions must be satisfied to complete the Business Combination?

There are a number of closing conditions in the Business Combination Agreement, including the approval by Qell shareholders of the Business Combination Proposal and the Merger Proposal and the Aggregate Holdco Transaction Proceeds Condition. For a summary of the conditions that must be satisfied or waived prior to completion of the Business Combination, please see the section entitled “The Business Combination Agreement and Ancillary Documents — Conditions to Closing of the Business Combination.”

What happens if the Business Combination Agreement is terminated or the Business Combination is not consummated?

There are certain circumstances under which the Business Combination Agreement may be terminated. Please see the section entitled “The Business Combination Agreement and Ancillary Documents” for information regarding the parties’ specific termination rights.

If Qell does not consummate the Business Combination, it may continue to try to complete a business combination with a different target business until October 2, 2022. If Qell fails to complete an initial business combination by October 2, 2022, then Qell will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem Qell public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable, and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish Qell public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of Qell’s remaining shareholders and the Qell Board, dissolve and liquidate, subject in the case of (ii) and (iii) to Qell’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be less than the initial public offering price per unit in the Qell IPO. Please see the section entitled “Risk Factors — Risks Related to Qell” for additional information.

Holders of Founder Shares have waived any right to any liquidation distribution with respect to such shares. In addition, there will be no redemption rights or liquidating distributions with respect to the Qell Public Warrants and Private Placement Warrants, which will expire worthless if Qell fails to complete an initial business combination by October 2, 2022.

When is the Business Combination expected to be completed?

The closing of the Business Combination is expected to commence on or prior to the third business day following the satisfaction or waiver of the conditions described below in the subsection entitled “The Business Combination Agreement and Ancillary Documents — Conditions to Closing of the Business

TABLE OF CONTENTS

Combination.” The Business Combination Agreement may be terminated by Qell or Lilium if the closing of the Business Combination has not occurred on or prior to the later of (i) the date that is six (6) calendar months after the date of the Business Combination Agreement, and (ii) the date that is six (6) calendar months following (A) notification from the BMWi, within six (6) calendar months of the Business Combination Agreement, that a certificate of non-objection is required in respect of the Transaction, or (B) the parties’ mutual decision, within six (6) calendar months of the Business Combination Agreement, to seek a certificate of non-objection from the BMWi (the “Termination Date”).

For a description of the conditions to the completion of the Business Combination, see the section entitled “The Business Combination Agreement and Ancillary Documents — Conditions to Closing of the Business Combination.”

What do I need to do now?

You are urged to read carefully and consider the information contained in this proxy statement/prospectus, including the Annexes, and to consider how the Business Combination will affect you as a shareholder. You should then vote as soon as possible in accordance with the instructions provided in this proxy statement/prospectus and on the enclosed proxy card or, if you hold your shares through a brokerage firm, bank or other nominee, on the voting instruction form provided by the broker, bank or nominee.

How do I vote?

If you hold your shares in “street name” and were a holder of record of Qell Ordinary Shares on , 2021, the record date for the General Meeting, you may vote with respect to the proposals in person at the General Meeting, or by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided. For the avoidance of doubt, the record date does not apply to Qell shareholders that hold their shares in registered form and are registered as shareholders in Qell’s register of members. All holders of shares in registered form on the day of the General Meeting are entitled to vote at the General Meeting.

Voting by Mail. By signing the proxy card and returning it in the enclosed prepaid and addressed envelope, you are authorizing the individuals named on the proxy card to vote your shares at the General Meeting in the manner you indicate. You are encouraged to sign and return the proxy card even if you plan to attend the General Meeting so that your shares will be voted if you are unable to attend the General Meeting. If you receive more than one proxy card, it is an indication that your shares are held in multiple accounts. Please sign and return all proxy cards to ensure that all of your shares are voted. Votes submitted by mail must be received by 5:00 p.m., New York City time, on , 2021.

Voting in Person at the Meeting. If you attend the General Meeting and plan to vote in person, you will be provided with a ballot at the General Meeting. If your shares are registered directly in your name, you are considered the shareholder of record and you have the right to vote in person at the General Meeting. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or other nominee, you should follow the instructions provided by your broker, bank or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the record holder of your shares with instructions on how to vote your shares or, if you wish to attend the General Meeting and vote in person, you will need to bring to the General Meeting a legal proxy from your broker, bank or nominee authorizing you to vote these shares. For additional information, please see the section entitled “General Meeting of Qell Shareholders.”

What will happen if I abstain from voting or fail to vote at the General Meeting?

At the General Meeting, a properly executed proxy marked “ABSTAIN” with respect to a particular proposal will be counted as present for purposes of determining whether a quorum is present. For purposes of approval, broker non-votes and abstentions will have no effect on the Business Combination Proposal, the Merger Proposal, the Incentive Plan Proposal, the ESPP Proposal or the Adjournment Proposal.

TABLE OF CONTENTS

What will happen if I sign and return my proxy card without indicating how I wish to vote?

Signed and dated proxies received by Qell without an indication of how the shareholder intends to vote on a proposal will be voted “FOR” each proposal presented to the shareholders. The proxyholders may use their discretion to vote on any other matters which properly come before the General Meeting.

If I am not going to attend the General Meeting in person, should I return my proxy card instead?

Yes. Whether you plan to attend the General Meeting or not, please read the enclosed proxy statement/prospectus carefully, and vote your shares by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided.

We intend to hold the General Meeting in person. However, we are sensitive to the public health and travel concerns our shareholders may have and recommendations that public health officials may issue in light of the evolving coronavirus (COVID-19) situation. As a result, we may impose additional procedures or limitations on meeting attendees or may decide to hold the meeting in a different location. We plan to announce any such updates on our proxy website, and we encourage you to check this website prior to the meeting if you plan to attend.

If my shares are held in “street name,” will my broker, bank or nominee automatically vote my shares for me?

No. Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee.

Qell believes that all of the proposals presented to the shareholders at this General Meeting will be considered non-discretionary and, therefore, your broker, bank, or nominee cannot vote your shares without your instruction on any of the proposals presented at the General Meeting. If you do not provide instructions with your proxy card, your broker, bank, or other nominee may deliver a proxy card expressly indicating that it is NOT voting your shares. This indication that a broker, bank, or nominee is not voting your shares is referred to as a “broker non-vote.” Broker non-votes will be counted for the purposes of determining the existence of a quorum but will not be counted for purposes of determining the number of votes cast at the General Meeting. Your broker, bank or other nominee can vote your shares only if you provide instructions on how to vote. You should instruct your broker, bank or other nominee to vote your shares in accordance with directions you provide.

May I change my vote after I have mailed my signed proxy card?

Yes. You may change your vote by sending a later-dated, signed proxy card to Qell’s Secretary at the address listed below so that it is received by Qell’s Secretary prior to the General Meeting or attend the General Meeting in person and vote. You also may revoke your proxy by sending a notice of revocation to Qell’s Secretary, which must be received by Qell’s Secretary prior to the General Meeting.

What should I do if I receive more than one set of voting materials?

You may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast your vote with respect to all of your shares.

Who will solicit and pay the cost of soliciting proxies for the General Meeting?

Qell will pay the cost of soliciting proxies for the General Meeting. Qell has engaged Morrow to assist in the solicitation of proxies for the General Meeting. Qell has agreed to pay Morrow a fee of $37,500, plus disbursements, and will reimburse Morrow for its reasonable out-of-pocket expenses and

indemnify Morrow and its affiliates against certain claims, liabilities, losses, damages and expenses. Qell will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of Qell Ordinary Shares for their expenses in forwarding soliciting materials to beneficial owners of Qell Ordinary Shares and in obtaining voting instructions from those owners. The directors, officers and employees of Qell may also solicit proxies by telephone, by facsimile, by mail, on the Internet, or in person.

Effect of the Business Combination on Existing Qell Equity

Subject to the terms and conditions of the Business Combination Agreement, the Business Combination will result in, among other things, the following:

•

each Qell Class A Ordinary Share will be converted into one fully paid and non-assessable Holdco Class A Share;

•

each Founder Share will be converted into one fully paid and non-assessable Holdco Class A Share;

•

each Qell Public Warrant will be converted into a Holdco Public Warrant, on the same terms and conditions as those applicable to the Qell Public Warrants; and

•

Sponsor will forfeit 1,828,945 Qell Class B Ordinary Shares that would otherwise have converted into 1,828,945 Holdco Shares in connection with the Merger for no consideration.

Consideration to Lilium Shareholders in the Business Combination

Subject to the terms and conditions of the Business Combination Agreement, the consideration to be received by the Lilium equityholders in connection with the Business Combination will be an aggregate number of Holdco Shares equal to (a) $2,400,000,000 (subject to certain downward adjustments set forth in the Business Combination Agreement), divided by (b) $10.00. Such calculation for the aggregate number of Holdco Shares to be received by Lilium equityholders is based upon assumptions (A), (B) and (C) described below in the section entitled “Ownership of Holdco.”

Ownership of Holdco

TABLE OF CONTENTS

In addition to the assumptions made in the preceding paragraph, the factors that will determine the ownership percentages upon consummation of the Business Combination include:

•

if the Participating Shareholders represent less than 100% of the issued and outstanding shares of Lilium prior to the Business Combination, it would reduce the aggregate ownership of the Lilium equityholders and increase the aggregate ownership of the other shareholder groups described above;

•

if there are any “change of control” payments made or required to be made by Lilium, it would reduce the aggregate ownership of the Lilium equityholders and increase the aggregate ownership of the other shareholder groups described above;

•

if there are any redemptions by public shareholders of Qell Class A Ordinary Shares in connection with the Business Combination, it would reduce the aggregate ownership of the public shareholders and increase the aggregate ownership of the other shareholder groups described above; and

•

if the PIPE Investors do not fund the PIPE Financing in full, it would reduce the aggregate ownership of the PIPE Investors and increase the aggregate ownership of the other shareholder groups described above commensurately.

For further information related to the determination of the number of Holdco Shares to be issued to the Lilium equityholders upon completion of the Business Combination, please see the section entitled “The Business Combination — Consideration to Lilium Shareholders in the Business Combination”.

Qell Board’s Reasons for Approval of the Business Combination

The Qell Board considered a number of factors pertaining to the Business Combination as generally supporting its decision to enter into the Business Combination Agreement and the transactions contemplated thereby, including but not limited to, the following material factors:

•

Large Market with Limited Competition: the market for regional air mobility represents a $1.5 – 3.0 trillion global opportunity that can be served by eVTOL aircraft that would replace expensive, time consuming infrastructure deployments such as rail and highways with affordable, emissions-free transportation that can be deployed quickly to multiple locations. Lilium is one of a limited number of technology companies globally with eVTOL technology that has matured through several generations.

•

Significant Barriers to Entry and Early Mover Advantage: global aerospace companies have significant regulatory and safety hurdles to overcome before aircraft can be deployed for use in movement of people and goods. Lilium has carefully advanced each successive generation of its aircraft since 2015, commenced its work with regulators in 2017 and achieved its certification basis with EASA in December 2020.

•

Proprietary and Scalable Technology: Lilium’s DEVT technology is fundamentally distinct from the open propeller technology used by other eVTOL companies. The DEVT approach enables Lilium to have a relatively high payload in the eVTOL industry, and quieter aircraft that can still fit on traditional heliport landing areas.

•

Attractive Entry Valuation: Lilium will have an anticipated initial pro forma enterprise value of $2.4 billion, implying a 0.7x multiple of 2026 projected revenue. The Qell Board believes this is attractive relative to relevant eVTOL comparable companies, as well as the broader universe of publicly traded electric vehicle, shared economy and LIDAR high technology companies. The Qell Board

TABLE OF CONTENTS

believes the valuation of Lilium is favorable to investors seeking long-term return potential and that the $2.4 billion enterprise value presents a compelling entry point valuation for a business with proprietary technology and significant barriers to entry.

•

Strong Shareholder Base: Lilium’s funding base (inclusive of the $450 million fully committed PIPE Financing) is anchored by strategic partners and institutional investors including Baillie Gifford, funds and accounts managed by BlackRock, Tencent, Ferrovial, LGT and its direct impact investing arm Lightrock, Palantir, and private funds affiliated with PIMCO.

•

Continued Ownership By Lilium Shareholders and Investment by Third Parties. The Qell Board considered that Lilium shareholders would exchange 100% of their Lilium shares for Holdco Shares and would remain, collectively, the largest stakeholders of Holdco. In addition, the Qell Board considered that the PIPE Investors, including existing Lilium shareholders and other strategic partners and institutional investors, are also investing an aggregate amount of $450 million in the combined company, in each case, pursuant to their participation in the PIPE Financing. The Qell Board considered the foregoing as a strong sign of confidence in Lilium following the Business Combination and the benefits to be realized as a result of the Business Combination.

Please see the section entitled “The Business Combination — The Qell Board’s Reasons for the Business Combination” for additional information.

The General Meeting of Qell Shareholders

Date, Time and Place of General Meeting

The General Meeting of Qell shareholders will be held on , 2021, at 9:00 a.m., New York City time, at the offices of Goodwin Procter LLP located at 620 Eighth Avenue, New York, New York 10018.

We intend to hold the General Meeting in person. However, we are sensitive to the public health and travel concerns our shareholders may have and recommendations that public health officials may issue in light of the evolving coronavirus (COVID-19) situation. As a result, we may impose additional procedures or limitations on meeting attendees or may decide to hold the meeting in a different location. We plan to announce any such updates on our proxy website, and we encourage you to check this website prior to the meeting if you plan to attend.

Proposals

At the General Meeting, Qell shareholders will be asked to consider and vote on:

Business Combination Proposal — To approve the entry by the Company into the Business Combination Agreement and the consummation of the transactions contemplated thereby, including the Business Combination (Proposal No. 1);

Merger Proposal — To authorize the Plan of Merger, and to approve the consummation of the Merger and the transactions contemplated thereby (Proposal No. 2);

Incentive Plan Proposal — Assuming the approval of the Business Combination Agreement Proposal and the Merger Proposal are approved, to consider and approve the Incentive Plan (Proposal No. 3);

ESPP Proposal — Assuming the approval of the Business Combination Agreement Proposal and the Merger Proposal are approved, to consider and approve the ESPP (Proposal No. 4); and

TABLE OF CONTENTS

Please see the sections entitled “Proposal No. 1 — The Business Combination Proposal”, “Proposal No. 2 — The Merger Proposal”, “Proposal No. 3 — The Incentive Plan Proposal”, “Proposal No. 4 — The ESPP Proposal”, and “Proposal No. 5 — The Adjournment Proposal.”

Voting Power; Record Date

For Qell shareholders holding their shares in “street name,” only holders of record at the close of business on , 2021, the record date for the General Meeting, will be entitled to vote at the General Meeting. Each Qell shareholder that holds its shares in “street name” is entitled to one vote for each Qell Ordinary Share that such shareholder owned as of the close of business on the record date. If a Qell shareholder’s shares are held in “street name” or are in a margin or similar account, such shareholder should contact its broker, bank or other nominee to ensure that votes related to the shares beneficially owned by such shareholder are properly counted. On the record date, there were Qell Ordinary Shares outstanding, of which are public shares and are shares held by the Sponsor and the Qell Initial Shareholders. For the avoidance of doubt, the record date does not apply to Qell shareholders that hold their shares in registered form and are registered as shareholders in Qell’s register of members. Qell shareholders that hold their shares in registered form are entitled to one vote on each proposal presented at the General Meeting for each Qell Ordinary Share held on the date of the General Meeting.

Vote of the Qell Initial Shareholders and Qell’s Other Directors and Officers

Prior to the Qell IPO, Qell entered into agreements with the Qell Initial Shareholders and the other current directors and officers of Qell, pursuant to which each agreed to vote any Qell Ordinary Shares owned by them in favor of an initial business combination. These agreements apply to the Qell Initial Shareholders, including Sponsor, as it relates to the Founder Shares and the requirement to vote all of the Founder Shares in favor of the Business Combination Proposal, the Merger Proposal and for all other proposals presented to Qell shareholders in this proxy statement/prospectus. As of the record date, the Qell Initial Shareholders that hold their shares in “street name,” the Sponsor and the other current directors and officers own Founder Shares, representing % of the Qell Ordinary Shares then outstanding and entitled to vote at the General Meeting.

The Sponsor has waived any redemption rights, including with respect to Qell Class A Ordinary Shares purchased in the Qell IPO or in the aftermarket, in connection with the Business Combination. The Founder Shares held by the Sponsor have no redemption rights upon the liquidation of Qell and will be worthless if no business combination is effected by Qell by October 2, 2022. However, the Sponsor and the current directors and officers are entitled to redemption rights upon the liquidation of Qell with respect to any public shares they may own.

Quorum and Required Vote for Proposals at the General Meeting

The approval of the Business Combination Proposal requires the affirmative vote of holders of at least a majority of Qell Ordinary Shares present and voting in person or by proxy at a quorate General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Business Combination Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Business Combination Proposal. The Sponsor has agreed to vote their Qell Ordinary Shares and any public shares purchased by them during or after the Qell IPO in favor of the Business Combination Proposal.

The approval of the Merger Proposal requires the affirmative vote of holders of at least two-thirds of Qell Ordinary Shares present and voting in person or by proxy at a quorate General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Merger Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Merger Proposal. The Sponsor has

TABLE OF CONTENTS

agreed to vote their Qell Ordinary Shares and any public shares purchased by them during or after the Qell IPO in favor of the Merger Proposal.

The approval of the Incentive Plan Proposal requires the affirmative vote of holders of a majority of the Qell Ordinary Shares present and voting in person or by proxy at a quorate General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Incentive Plan Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Incentive Plan Proposal.

The approval of the ESPP Proposal requires the affirmative vote of holders of at least a majority of Qell Ordinary Shares present and voting in person or by proxy at a quorate General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the ESPP Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the ESPP Proposal.

The approval of the Adjournment Proposal requires the affirmative vote of holders of a majority of the Qell Ordinary Shares present and voting in person or by proxy at a quorate General Meeting. Accordingly, a Qell shareholder’s failure to vote by proxy or to vote in person at the General Meeting will not be counted towards the number of Qell Ordinary Shares required to validly establish a quorum, and if a valid quorum is otherwise established, such failure to vote will have no effect on the outcome of any vote on the Adjournment Proposal. Broker non-votes and abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Adjournment Proposal.

For the purposes of the Business Combination Proposal, one or more shareholders who together hold a simple majority of the issued and outstanding Qell Ordinary Shares entitled to vote at the General Meeting must be present, in person or represented by proxy, at the General Meeting to constitute a quorum and in order to conduct business at the General Meeting. In respect of each other proposal, one or more shareholders who together hold one third of the issued and outstanding Qell Ordinary Shares entitled to vote at the General Meeting must be present, in person or represented by proxy, at the General Meeting to constitute a quorum and in order to conduct business at the General Meeting. Broker non-votes and abstentions will be counted as present for the purpose of determining a quorum. The Sponsor, who currently owns % of the issued and outstanding Qell Ordinary Shares, will count towards this quorum. In the absence of a quorum, the chairman of the General Meeting has power to adjourn the General Meeting. As of the record date for the General Meeting for Qell shareholders that hold their shares in “street name,” Qell Ordinary Shares would be required to achieve a quorum.

It is important for you to note that, in the event that the Business Combination Proposal or the Merger Proposal does not receive the requisite vote for approval, Qell will not consummate the Business Combination. If Qell does not consummate the Business Combination and fails to complete an initial business combination by October 2, 2022, Qell will be required to dissolve and liquidate the Trust Account by returning the then remaining funds in such account to the public shareholders.

Recommendation to Qell Shareholders

The Qell Board believes that each of the Business Combination Proposal, the Merger Proposal, the Incentive Plan Proposal, the ESPP Proposal, and the Adjournment Proposal to be presented at the General Meeting is in the best interests of Qell and its shareholders and recommends that its shareholders vote “FOR” each of the proposals.

TABLE OF CONTENTS

Interests of Certain Persons in the Business Combination

In considering the recommendation of the Qell Board to vote in favor of the Business Combination, Qell shareholders should be aware that aside from their interests as shareholders, the Sponsor, Qell Initial Shareholders and Qell’s other current officers and directors have interests in the Business Combination that are different from, or in addition to, those of other Qell shareholders generally. The Qell Board was aware of and considered these interests, among other matters, in evaluating and negotiating the Business Combination, and in recommending to Qell shareholders that they approve the Business Combination Proposal. Qell shareholders should take these interests into account in deciding whether to approve the Business Combination Proposal.

These interests include:

•

the fact that the Sponsor has agreed not to redeem any Qell Ordinary Shares held by them in connection with a shareholder vote to approve a proposed initial business combination;

•

the fact that the Sponsor has agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if Qell fails to complete an initial business combination by October 2, 2022;

•

the fact that the Registration Rights Agreement will be entered into by the Sponsor;

•

the fact that Sponsor paid an aggregate of $10,590,000 for its 7,060,000 Private Placement Warrants and that such Private Placement Warrants will expire worthless if a business combination is not consummated by October 2, 2022;

•

the fact that, at the option of Sponsor, any amounts outstanding under certain working capital loans made by Sponsor or any of its affiliates to Qell in an aggregate amount of up to $1,500,000 may be converted into warrants to purchase Qell Class A Ordinary Shares which will be identical to the Private Placement Warrants;

•

the right of the Sponsor to receive Holdco Shares, subject to certain lock-up periods;

•

the continued indemnification of Qell’s existing directors and officers and the continuation of Qell’s directors’ and officers’ liability insurance after the Business Combination;

•

Redemption Rights

TABLE OF CONTENTS

validly redeem its shares. Notwithstanding the foregoing, a holder of the public shares, together with any affiliate of his or her or any other person with whom he or she is acting in concert or as a “group” (as defined in Section 13 of the Exchange Act) will be restricted from seeking redemption rights with respect to more than fifteen percent (15%) of the Qell Class A Ordinary Shares included in the Qell Public Units sold in the Qell IPO. Accordingly, all public shares in excess of the 15% threshold beneficially owned by a public shareholder or group will not be redeemed for cash.

Qell has no specified maximum redemption threshold under its amended and restated memorandum and articles of association, other than the aforementioned 15% threshold. Each redemption of Qell Class A Ordinary Shares by Qell public shareholders will reduce the amount in the Trust Account, which held marketable securities with a fair value of approximately $ as of , 2021. The Business Combination Agreement provides that Lilium’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (after giving effect to the Qell Shareholder Redemption) together with the proceeds actually received from the PIPE Financing being at least $450,000,000. The committed PIPE subscriptions are sufficient to satisfy this condition if fully funded, even if existing Qell shareholders exercise their redemption rights. The conditions to closing in the Business Combination Agreement are for the sole benefit of the parties thereto and may be waived by such parties. In no event will Qell redeem its Qell Class A Ordinary Shares in an amount that would cause its net tangible assets to be less than $5,000,001, as provided in the Qell amended and restated memorandum and articles of association and as required as a closing condition to each party’s obligation to consummate the Business Combination under the terms of the Business Combination Agreement. Qell shareholders who wish to redeem their public shares for cash must refer to and follow the procedures set forth in the section entitled “General Meeting of Qell Shareholders — Redemption Rights” in order to properly redeem their public shares.

Holders of Qell Public Warrants will not have redemption rights with respect to such warrants.

Certain Information Relating to Holdco

Listing of Holdco Shares and Holdco Public Warrants on Nasdaq

Holdco Shares and Holdco Public Warrants currently are not traded on a stock exchange. Holdco intends to apply to list the Holdco Class A Shares and Holdco Public Warrants on Nasdaq under the symbols “LILM” and “LILMW,” respectively, upon the closing of the Business Combination. We cannot assure you that the Holdco Shares or Holdco Public Warrants will be approved for listing on Nasdaq.

Delisting of Qell Ordinary Shares and Deregistration of Qell

Qell and Lilium anticipate that, following consummation of the Business Combination, the Qell Class A Ordinary Shares, Qell Public Units and Qell Public Warrants will be delisted from Nasdaq, and Qell will be deregistered under the Exchange Act.

Emerging Growth Company; Foreign Private Issuer

Holdco is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Holdco will remain an “emerging growth company” until the earliest to occur of (i) the last day of the fiscal year (a) following the fifth anniversary of the closing of the Business Combination, (b) in which Holdco has total annual gross revenue of at least $1.07 billion or (c) in which Holdco is deemed to be a large accelerated filer, which means the market value of Holdco Shares held by non-affiliates exceeds $700 million as of the last business day of Holdco’s prior second fiscal quarter, and (ii) the date on which Holdco issued more than $1.0 billion in non-convertible debt during the prior three-year period. Holdco intends to take advantage of exemptions from various reporting requirements that are applicable to most other public companies, whether or not they are classified as “emerging growth companies,” including, but not limited to, an exemption from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that Holdco’s independent registered public accounting firm provide an attestation report on the effectiveness of its internal control over financial reporting and reduced disclosure obligations regarding executive compensation.

As a “foreign private issuer,” Holdco will be subject to different U.S. securities laws than domestic U.S. issuers. The rules governing the information that Holdco must disclose differ from those governing U.S.

TABLE OF CONTENTS

corporations pursuant to the Exchange Act. Holdco will be exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders. Those proxy statements are not expected to conform to Schedule 14A of the proxy rules promulgated under the Exchange Act. As a foreign private issuer, Holdco will be exempt from a number of rules under the U.S. securities laws and will be permitted to file less information with the SEC than a U.S. company. In addition, as a “foreign private issuer,” Holdco’s officers and directors and holders of more than 10% of the issued and outstanding Holdco Shares, will be exempt from the rules under the Exchange Act requiring insiders to report purchases and sales of ordinary shares as well as from Section 16 short swing profit reporting and liability.

Comparison of Shareholder Rights

Until consummation of the Merger, Cayman Islands law and the Qell amended and restated memorandum and articles of association will continue to govern the rights of Qell shareholders. After consummation of the Merger, Dutch law and the Holdco Articles of Association will govern the rights of Holdco shareholders.

There are certain differences in the rights of Qell shareholders prior to the Business Combination and the rights of Holdco shareholders after the Business Combination. Please see the section entitled “Comparison of Shareholder Rights.”

Material Tax Considerations

Subject to the limitations and qualifications described in “Material Tax Considerations — Material U.S. Federal Income Tax Considerations” the Merger (together with the making of the election for Merger Sub to be treated as a disregarded entity for U.S. federal income tax purposes) will constitute a reorganization under Section 368(a)(1)(F) of the Code. As a result, that Qell shareholders and warrant holders will generally not recognize gain or loss for U.S. federal income tax purposes on the receipt of Holdco Class A Shares for Qell Class A Ordinary Shares and Holdco Public Warrants for Qell Public Warrants in connection with the Merger.

Holders of Qell Ordinary Shares and Qell Public Warrants should read carefully the information included under “Material Tax Considerations” for a detailed discussion of material U.S. federal income tax consequences of the Merger and the Cayman Islands, German and Dutch tax consequences of the Business Combination, including the receipt of cash pursuant to the exercise of redemption rights with respect to the Qell Class A Ordinary Shares, and the material U.S. federal and Cayman Islands, German and Dutch tax consequences of the ownership and disposition of Holdco Class A Shares and Holdco Public Warrants after the Business Combination. Holders of Qell Ordinary Shares and Qell Public Warrants are urged to consult their tax advisors to determine the tax consequences to them (including the application and effect of any state, local or other income and other tax laws) of the Business Combination, including the U.S. federal income tax consequences and the Cayman Islands, German and Dutch tax consequences of the acquisition holding, redemption and disposal of Holdco Class A Shares or acquisition, holding, exercise or disposal of Holdco Public Warrants.

Accounting Treatment of the Business Combination

The Business Combination will be accounted for as a capital reorganization. Under this method of accounting, Qell will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination will be treated as the equivalent of Lilium issuing shares at the closing of the Business Combination for the net assets of Qell as of the closing date, accompanied by a recapitalization. The net assets of Qell will be stated at historical cost, with no goodwill or other intangible assets recorded.

Lilium has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

•

Lilium’s shareholders will have the largest voting interest in Holdco under both the no redemption and maximum redemption scenarios;

•

The board of directors of the post-combination company has seven members, and Lilium has the ability to nominate the majority of the members of the board of directors;

•

Lilium’s senior management is the senior management of the post-combination company;

TABLE OF CONTENTS

•

The business of Lilium will comprise the ongoing operations of Holdco; and

•

Lilium is the larger entity, in terms of substantive operations and employee base.

The Business Combination, which is not within the scope of IFRS 3 — Business Combinations (“IFRS 3”) since Qell does not meet the definition of a business in accordance with IFRS 3, is accounted for within the scope of IFRS 2 — Share-based payment (“IFRS 2”). Any excess of fair value of Holdco’s Shares issued over the fair value of Qell’s identifiable net assets acquired represents compensation for the service of a stock exchange listing for its shares and is expensed as incurred.

Appraisal Rights

Appraisal rights are not available to holders of Qell shares or Lilium shares in connection with the Business Combination.

Proxy Solicitation

Proxies may be solicited by mail, via telephone or via e-mail or other electronic correspondence. Qell has engaged to assist in the solicitation of proxies.

If a Qell shareholder grants a proxy, such shareholder may still vote its shares in person if it revokes its proxy before the General Meeting. A Qell shareholder may also change its vote by submitting a later-dated proxy, as described in the section entitled “General Meeting of Qell Shareholders — Revoking Your Proxy.”

Risk Factor Summary

In evaluating the Business Combination and the proposals to be considered and voted on at the General Meeting, you should carefully review and consider the matters addressed under the heading “Cautionary Note Regarding Forward-Looking Statements” and the risk factors set forth under “Risk Factors”, a summary of which is set forth below:

Risks Related to Lilium’s Business

•

Lilium has incurred significant losses and expect to incur significant expenses and continuing losses for the foreseeable future, and it may not achieve or maintain profitability.

•

The eVTOL market may not continue to develop, or eVTOL aircraft may not be adopted by the transportation market.

•

Lilium’s eVTOL aircraft may not be certified by transportation and aviation authorities, including EASA or the FAA.

•

The Lilium Jet may not deliver the expected reduction in operating costs or time savings that Lilium anticipates.

•

The success of Lilium’s business depends on the safety and positive perception of the Lilium Jets, the convenience of Lilium’s vertiports, and Lilium’s ability to effectively market and sell Regional Air Mobility services.

•

Lilium has a limited operating history and faces significant challenges to develop, certify, manufacture and launch its services in a new industry, urban and regional air transportation services. The Lilium eVTOL jet remains in development, and Lilium does not expect to launch commercial services until 2024, at the earliest, if at all.

•

The Regional Air Mobility market for eVTOL passenger and goods transport services does not exist; whether and how it develops is based on assumptions, and the Regional Air Mobility market may not achieve the growth potential Lilium expect or may grow more slowly than expected.

•

Lilium may be unable to adequately control the costs associated with its pre-launch operations, and its costs will continue to be significant after Lilium commences operations.

•

Lilium may experience difficulties in managing its growth and commercializing its operations.

TABLE OF CONTENTS

•

Lilium’s business model has yet to be tested or regulatorily approved and any failure to commercialize its strategic plans would have an adverse effect on its operating results and business, harm its reputation and could result in substantial liabilities that exceed its resources.

•

Lilium’s forward-looking operating information and business plan forecast relies in large part upon assumptions and analyses that Lilium has developed. If these assumptions or analyses prove to be incorrect, its actual operating results may be materially different from its forecasted results.

•

Lilium anticipates commencing commercial operations with its fully developed Lilium Jet, if regulatorily approved and certified, which is currently in design and development phase and has yet to complete the testing and certification process. Any delay in completing testing and certification, and any design changes that may be required to be implemented in order to receive certification, would adversely impact its business plan and financial forecasts and its financial condition.

•

Any delays in the development, certification, manufacture and commercialization of the Lilium Jets and related technology, such as battery technology or electric motors, may adversely impact its business, financial condition and results of operations.

•

If Lilium is unable to successfully design, manufacture and obtain regulatory approval and certification of its jets, or if the jets Lilium builds fail to perform as expected, its ability to develop, market, and sell its services could be harmed.

•

The Lilium Jets require complex software, battery technology and other technology systems that remain in development in coordination with its vendors and suppliers to complete serial production.

•

Lilium will rely on third-party suppliers for the provision and development of key emerging technologies, components and materials used in the Lilium Jet, such as the lithium-ion batteries that will power the jets, a significant number of which may be single or limited source suppliers.

•

If any of Lilium’s suppliers become economically distressed or go bankrupt, Lilium may be required to provide substantial financial support or take other measures to ensure supplies of components or materials, which could increase its costs, affect its liquidity or cause production disruptions.

•

Third-party U.S. air carriers will provide Regional Air Mobility services in the U.S. using the Lilium eVTOL aircraft. These third-party U.S. air carriers are subject to substantial regulation and laws, and unfavorable changes to, or the third-party U.S. air carriers’ failure to comply with, these regulations and/or laws could substantially harm Lilium’s business and operating results in the U.S.

•

Lilium is subject to substantial regulation and laws and unfavorable changes to, or its failure to comply with, these regulations and/or laws could substantially harm its business and operating results.

•

Any inability to operate its Regional Air Mobility services after commercial launch at its anticipated flight rate, on its anticipated routes or with its anticipated vertiports could adversely impact its business, financial condition and results operations.

•

Lilium’s potential customers may not generally accept the Regional Air Mobility industry or its passenger or goods transport services. If Lilium is unable to convince customers of the convenience of its services and generally provide high quality customer service that will be expected of a premium service, its business and reputation may be materially and adversely affected

•

Adverse publicity stemming from any incident involving Lilium or its competitors, or an incident involving any air travel service or unmanned flight based on autonomous technology, could have a material adverse effect on its business, financial condition and results of operations.

•

Although Lilium hopes to be the first to bring eVTOL Regional Air Mobility services to market, its competitors have also displayed eVTOL prototypes and may gain certification and commercialize their vehicles to allow them to enter the market before Lilium.

•

Lilium’s business plans require a significant amount of capital. In addition, its future capital needs may require us to sell additional equity or debt securities that may adversely affect the market price of its shares and dilute its shareholders or introduce covenants that may restrict its operations.

Other Risks

•

Qell does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for Qell to complete a business combination with which a substantial majority of its shareholders do not agree.

•

A shareholder or “group” of shareholders deemed to hold an aggregate of more than 15% of the Qell Class A Ordinary Shares issued in the Qell IPO will lose the ability to redeem all such shares in excess of 15% of the Qell Class A Ordinary Shares issued in the Qell IPO.

•

There is no guarantee that a shareholder’s decision whether to redeem its shares for a pro rata portion of the Trust Account will put the shareholder in a better future economic position.

•

Shareholders of Qell who wish to redeem their shares for a pro rata portion of the Trust Account must comply with specific requirements for redemption, which may make it difficult for them to exercise their redemption rights prior to the deadline. If shareholders fail to comply with the redemption requirements specified in this proxy statement/prospectus, they will not be entitled to redeem their Qell Class A Ordinary Shares for a pro rata portion of the funds held in the Trust Account.

•

If a public shareholder fails to receive notice of Qell’s offer to redeem its public shares in connection with the Business Combination, or fails to comply with the procedures for tendering its shares, such shares may not be redeemed.

TABLE OF CONTENTS

SUMMARY UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following summary of unaudited pro forma condensed combined financial information (the “Summary Pro Forma Information”) gives effect to the Business Combination and related transactions contemplated in the Business Combination Agreement. The Business Combination will be accounted for as a capital reorganization in accordance with IFRS as issued by the IASB. Under this method of accounting, Qell will be treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination will be treated as the equivalent of Lilium issuing shares at the closing of the Business Combination for the net assets of Qell as of the closing date, accompanied by a recapitalization. The net assets of Qell will be stated at historical cost, with no goodwill or other intangible assets recorded.

The summary unaudited pro forma condensed combined statement of financial position data as of December 31, 2020 gives pro forma effect to the Business Combination and related transactions as if they had occurred on December 31, 2020. The summary unaudited pro forma condensed combined statement of operations data for the year ended December 31, 2020 give pro forma effect to the Business Combination and related transactions as if they had been consummated on January 1, 2020.

The summary pro forma information have been derived from, and should be read in conjunction with, the unaudited pro forma condensed combined financial information of the combined company appearing elsewhere in this proxy statement/prospectus and the accompanying notes thereto. The unaudited pro forma condensed combined financial information is based upon, and should be read in conjunction with, the historical financial statements of Qell and related notes and the historical consolidated financial statements of Lilium and related notes included in this proxy statement/prospectus.

The summary pro forma information have been presented for informational purposes only and are not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the Business Combination and related transactions been completed as of the dates indicated. In addition, the summary pro forma information do not purport to project the future financial position or operating results of the combined company.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption by Qell shareholders of Qell Class A Ordinary Shares for cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account:

•

Assuming No Redemptions: This presentation assumes that no public shareholders of Qell exercise redemption rights with respect to their public shares for a pro rata share of cash in the Trust Account.

•

Assuming Maximum Redemptions: This presentation assumes that 37,950,000 of Qell Class A Ordinary Shares are redeemed for their pro rata share of the cash in the Trust Account in connection with the Qell Share Redemptions. This scenario gives effect to Qell Share Redemptions of 37,950,000 Qell Class A Ordinary Shares for aggregate redemption payments of €310.7 million at a redemption price of approximately €8.19 per share based on the investments held in the Trust Account as of December 31, 2020. The Business Combination Agreement includes as a condition to closing the Business Combination that, at Closing, Holdco will receive aggregate transaction proceeds of $450.0 million comprising (i) the cash held in the Trust Account after giving effect to the Qell Shareholder Redemption and (ii) aggregate proceeds from the PIPE Financing.

RISK FACTORS

Risks Related to Qell

The Qell Initial Shareholders and Qell’s other current officers and directors have interests in the Business Combination that are different from or are in addition to other Qell shareholders in recommending that Qell shareholders vote in favor of approval of the Business Combination Proposal and approval of the other proposals described in this proxy statement/prospectus.

When considering the Qell Board’s recommendation that Qell shareholders vote in favor of the approval of the Business Combination Proposal, Qell shareholders should be aware that aside from their interests as shareholders, the Qell Initial Shareholders and Qell’s other current officers and directors have interests in the Business Combination that are different from, or in addition to, those of other Qell shareholders generally. These interests include:

•

the Sponsor has agreed not to redeem any Qell Ordinary Shares held by them in connection with a shareholder vote to approve a proposed initial business combination;

•

the Sponsor paid an aggregate of $25,000 for the Founder Shares and such securities will have a significantly higher value at the time of the Business Combination which, if unrestricted and freely tradable, would be valued at approximately $76,585,550, taking into account the 1,828,945 Founder Shares that the Sponsor has agreed to forfeit in connection with the Business Combination;

•

the Sponsor has agreed to waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if Qell fails to complete an initial business combination by October 2, 2022;

•

the Registration Rights Agreement will be entered into by the Sponsor;

•

the Sponsor paid an aggregate of $10,590,000 for its 7,060,000 Private Placement Warrants and that such Private Placement Warrants will expire worthless if a business combination is not consummated by October 2, 2022;

•

at the option of the Sponsor, any amounts outstanding under certain working capital loans made by the Sponsor or any of its affiliates to Qell in an aggregate amount of up to $1,500,000 may be converted into warrants to purchase Qell Class A Ordinary Shares which will be identical to the Private Placement Warrants;

•

the right of the Sponsor to receive Holdco Shares, subject to certain lock-up periods;

•

the continued indemnification of Qell’s existing directors and officers and the continuation of Qell’s directors’ and officers’ liability insurance after the Business Combination;

•

the Sponsor and Qell’s officers and directors will lose their entire investment in Qell and will not be reimbursed for any out-of-pocket expenses if an initial business combination is not consummated by October 2, 2022; and

•

if the Trust Account is liquidated, including in the event Qell is unable to complete an initial business combination within the required time period, the Sponsor has agreed to indemnify Qell to ensure that the proceeds in the Trust Account are not reduced below $10.00 per public share, or such lesser per public share amount as is in the Trust Account on the liquidation date, by the claims of prospective target businesses with which Qell has entered into an acquisition agreement or claims of any third party for services rendered or products sold to Qell, but only if such a vendor or target business has not executed a waiver of any and all rights to seek access to the Trust Account.

Qell shareholders will have a reduced ownership and voting interest after the Business Combination and will exercise less influence over management.

Upon the issuance of the Holdco Class A Shares to Qell shareholders and completion of the PIPE Financing, current Qell shareholders’ percentage ownership will be diluted. Subject to certain assumptions and assuming no public shareholders exercise their redemption rights, current Qell shareholders’ percentage ownership in Holdco following the issuance of shares to Qell shareholders would be approximately 11.4%

TABLE OF CONTENTS

on a fully diluted basis. Additionally, of the expected members of the Holdco Board after the completion of the Business Combination, only one is expected to be a current director of Qell. The percentage of Holdco Shares that will be owned by current Qell shareholders as a group will vary based on the number of Qell Class A Ordinary Shares for which the holders thereof request redemption in connection with the Business Combination. Because of this, current Qell shareholders, as a group, will have less influence on the board of directors, management and policies of Holdco than they now have on the board of directors, management and policies of Qell.

The structure of Holdco Shares will have the effect of concentrating voting power with Daniel Wiegand, which will limit an investor’s ability to influence the outcome of important transactions, including a change in control.

Holdco Class B Shares have three times as many votes per share than Holdco Class A Shares. Existing shareholders of Lilium are expected to hold substantially all of the issued and outstanding shares in Holdco. Accordingly, they will hold the majority of the voting power of Holdco Shares and will be able to control matters submitted to its shareholders for approval, including the election of directors, amendments of its organizational documents and any merger, consolidation, sale of all or substantially all of our assets or other major corporate transactions. The existing Lilium shareholders may have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentrated control may have the effect of delaying, preventing or deterring a change in control of Holdco, could deprive its shareholders of an opportunity to receive a premium for their ordinary shares as part of a sale of Holdco, and might ultimately affect the market price of shares of the Holdco Class A Shares.

Qell is not required to obtain an opinion from an independent investment banking firm or from an independent accounting firm, and consequently, you may have no assurance from an independent source that the price Qell is paying for the business is fair to Qell from a financial point of view.

Qell is not required to, and did not, obtain an opinion from an independent investment banking firm that is a member of the Financial Industry Regulatory Authority (“FINRA”), or from an independent accounting firm, that the consideration Qell shareholders will receive under the Business Combination Agreement is fair to Qell shareholders from a financial point of view. Qell’s public shareholders are therefore relying on the judgment of the Qell Board, who determined fair market value based on standards generally accepted by the financial community. The Sponsor and Qell’s executive officers and directors have interests in the Business Combination that are different from, or in addition to, those of other Qell shareholders generally. The Qell Board was aware of and considered those interests, among other matters, in evaluating and negotiating the Business Combination and in recommending to Qell shareholders that they approve the Business Combination Proposal. Please see the section entitled “The Business Combination — Interests of Certain Persons in the Business Combination” for more information.

The Sponsor will control the election of the Qell Board until consummation of a business combination and hold a substantial interest in Qell. As a result, they will elect all of Qell’s directors and may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support.

The Sponsor (and so Qell Initial Shareholders, indirectly) own 20% of the issued and outstanding Qell Ordinary Shares. In addition, the Founder Shares, all of which are held by the Sponsor, entitle the holders thereof to elect all of Qell’s directors prior to the initial business combination. Holders of Qell Class B Ordinary Shares have the exclusive right prior to Qell’s initial business combination to elect Qell’s directors. Accordingly, as holders of the Qell Class A Ordinary Shares, Qell’s public shareholders will not have the right to vote on the election of directors prior to consummation of the Business Combination. These provisions of the Qell amended and restated memorandum and articles of association may only be amended by a special resolution passed by holders representing a two-thirds majority of the Founder Shares. As a result, holders of Qell’s public shares will not have any influence over the election of directors of Qell prior to an initial business combination.

In addition, as a result of their substantial interest in Qell, the Sponsor (and other Qell Initial Shareholders) may exert a substantial influence on other actions requiring a shareholder vote, potentially in a manner that Qell shareholders do not support, including amendments to the Qell amended and restated

TABLE OF CONTENTS

memorandum and articles of association and approval of major corporate transactions, including the Business Combination. If the Qell Initial Shareholders purchase any Qell Class A Ordinary Shares in the aftermarket or in privately negotiated transactions, this would increase their influence over these actions. Accordingly, the Qell Initial Shareholders will exert significant influence over actions requiring a shareholder vote at least until the completion of a business combination.

The Sponsor and Qell’s other directors, executive officers, advisors and their affiliates may elect to purchase shares from Qell public shareholders, which may influence a vote on the Business Combination.

The Sponsor or Qell’s other directors, executive officers, advisors or their affiliates may purchase Qell Class A Ordinary Shares in privately negotiated transactions or in the open market prior to the completion of the Business Combination, although they are under no obligation to do so. Such a purchase may include a contractual acknowledgement that such shareholder, although still the record holder of the Qell Class A Ordinary Shares, is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that the Sponsor or Qell’s other directors, executive officers, advisors or their affiliates purchase shares in privately negotiated transactions from public shareholders who have already elected to exercise their redemption rights, such selling shareholders would be required to revoke their prior elections to redeem their shares. The purpose of such purchases would be to vote such shares in favor of the Business Combination and thereby increase the likelihood of obtaining shareholder approval of the Business Combination, where it appears that such approval would otherwise not be met. This may result in the completion of the Business Combination that may not otherwise have been possible.

You will not have any rights or interests in funds from the Trust Account, except under certain limited circumstances. To liquidate your investment, therefore, you may be forced to sell your Qell Public Units, Qell Class A Ordinary Shares or Qell Public Warrants, potentially at a loss.

Qell’s public shareholders will be entitled to receive funds from the Trust Account only upon the earlier to occur of: (i) the completion of an initial business combination; (ii) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Qell amended and restated memorandum and articles of association to modify the substance or timing of Qell’s obligation to redeem 100% of the public shares if Qell does not complete a business combination by October 2, 2022; and (iii) the redemption of all of the public shares if Qell is unable to complete a business combination by October 2, 2022, subject to applicable law. In no other circumstances will a public shareholder have any right or interest of any kind in the Trust Account. Accordingly, to liquidate your investment, you may be forced to sell your Qell Public Units, Qell Class A Ordinary Shares or Qell Public Warrants, potentially at a loss.

If Qell is unable to complete a business combination by October 2, 2022, Qell will cease all operations except for the purpose of winding up and Qell will redeem the public shares and liquidate.

The Sponsor and Qell’s executive officers and directors have agreed that Qell must complete a business combination by October 2, 2022. If Qell has not completed an initial business combination within such time period, it will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest, net of tax (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of Qell’s remaining shareholders and the Qell Board, dissolve and liquidate, subject in the case of clauses (ii) and (iii) to Qell’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be less than the initial public offering price per unit in the Qell IPO. In addition, if Qell fails to complete an initial business combination by October 2, 2022, there will be no redemption rights on liquidating distributions with respect to Qell Public Warrants or the Private Placement Warrants, which will expire worthless.

TABLE OF CONTENTS

If the Business Combination is not completed, new potential target businesses may have leverage over Qell in negotiating a business combination and Qell’s ability to conduct due diligence on a business combination as it approaches its dissolution deadline may decrease, which could undermine Qell’s ability to complete a business combination on terms that would produce value for Qell’s shareholders.

If Qell is unable to complete this Business Combination, any new potential target business with which Qell enters into negotiations concerning a business combination will be aware that Qell must complete an initial business combination by October 2, 2022. Consequently, a potential target may obtain leverage over Qell in negotiating a business combination, knowing that Qell may be unable to complete a business combination with another target business by October 2, 2022. This risk will increase as Qell gets closer to the timeframe described above. In addition, Qell may have limited time to conduct due diligence and may enter into a business combination on terms that Qell would have rejected upon a more comprehensive investigation.

Because of Qell’s limited resources and the significant competition for business combination opportunities, if this Business Combination is not completed, it may be more difficult for Qell to complete an initial business combination. In addition, resources could be wasted in researching acquisitions that are not completed, which could materially adversely affect subsequent attempts to locate and acquire or merge with another business. If Qell is unable to complete an initial business combination by October 2, 2022, Qell’s public shareholders may receive only approximately $10.00 per share, on the liquidation of the Trust Account (or less than $10.00 per share in certain circumstances where a third party brings a claim against Qell that the Sponsor is unable to indemnify), and the Qell Public Warrants will expire worthless.

If Qell is unable to complete this Business Combination, Qell would expect to encounter intense competition from other entities having a business objective similar to its business objective, including private investors (which may be individuals or investment partnerships), other blank check companies and other entities, domestic and international, competing for the types of businesses Qell could acquire. Many of these individuals and entities are well-established and have extensive experience in identifying and effecting, directly or indirectly, acquisitions of companies operating in or providing services to various industries. Many of these competitors possess greater technical, human and other resources or more local industry knowledge than Qell does and Qell’s financial resources will be relatively limited when contrasted with those of many of these competitors. While Qell believes there are numerous target businesses Qell could potentially acquire with the net proceeds of the Qell IPO and the sale of the Private Placement Warrants, Qell’s ability to compete with respect to the acquisition of certain target businesses that are sizable will be limited by Qell’s available financial resources. This inherent competitive limitation may give others an advantage in pursuing the acquisition of certain target businesses. Furthermore, if Qell is obligated to pay cash for the public shares redeemed and, in the event Qell seeks shareholder approval of a business combination, Qell makes purchases of its public shares, potentially reducing the resources available to Qell for a business combination. Any of these obligations may place Qell at a competitive disadvantage in successfully negotiating a business combination.

Qell anticipates that, if Qell is unable to complete this Business Combination, the investigation of other specific target business and the negotiation, drafting and execution of relevant agreements, disclosure documents and other instruments will require substantial management time and attention and substantial costs for accountants, attorneys and others. If Qell decides not to complete a specific business combination, the costs incurred up to that point for the proposed transaction likely would not be recoverable. Furthermore, if Qell reaches an agreement relating to a specific target business, Qell may fail to complete such business combination (including the Business Combination described in this proxy statement/prospectus) for any number of reasons including those beyond Qell’s control. Any such event will result in a loss to Qell of the related costs incurred which could materially adversely affect subsequent attempts to locate and acquire or merge with another business.

If Qell does not complete this Business Combination and is unable to complete an initial business combination by October 2, 2022, Qell’s public shareholders may receive only approximately $10.00 per share on the liquidation of the Trust Account (or less than $10.00 per share in certain circumstances where a third party brings a claim against Qell that the Sponsor is unable to indemnify) and the Qell Public Warrants will expire worthless.

TABLE OF CONTENTS

The exercise of discretion by Qell’s directors and officers in agreeing to changes to the terms of or waivers of closing conditions in the Business Combination Agreement may result in a conflict of interest when determining whether such changes to the terms of the Business Combination Agreement or waivers of conditions are appropriate and in the best interests of the public shareholders of Qell.

In the period leading up to the closing of the Business Combination, other events may occur that, pursuant to the Business Combination Agreement, would require Qell to agree to amend the Business Combination Agreement, to consent to certain actions or to waive rights that Qell is entitled to under those agreements. Such events could arise because of changes in the course of Lilium’s business, a request by the Lilium shareholders or Lilium to undertake actions that would otherwise be prohibited by the terms of the Business Combination Agreement or the occurrence of other events that would have a material adverse effect on Lilium’ business and would entitle Qell to terminate the Business Combination Agreement. In any of such circumstances, it would be in the discretion of Qell, acting through the Qell Board, to grant its consent or waive its rights. The existence of the financial and personal interests of Qell’s directors described elsewhere in this proxy statement/prospectus may result in a conflict of interest on the part of one or more of the directors between what he or she may believe is best for Qell and the public shareholders of Qell and what he or she may believe is best for himself or herself or his or her affiliates in determining whether or not to take the requested action. As of the date of this proxy statement/prospectus, Qell does not believe there will be any changes or waivers that Qell’s directors and officers would be likely to make after shareholder approval of the Business Combination has been obtained. While certain changes could be made without further shareholder approval, if there is a change to the terms of the Business Combination that would have a material impact on the shareholders, Qell will be required to circulate a new or amended proxy statement/prospectus or supplement thereto and resolicit the vote of the Qell public shareholders with respect to the Business Combination Proposal.

The unaudited pro forma condensed combined financial information included in this proxy statement/prospectus is preliminary and the actual financial condition and results of operations after the Business Combination may differ materially.

The unaudited pro forma financial information included in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what Holdco’s actual financial position or results of operations would have been had the Business Combination been completed on the date(s) indicated. The preparation of the pro forma financial information is based upon available information and certain assumptions and estimates that Qell and Lilium currently believe are reasonable. The unaudited pro forma condensed combined information does not purport to indicate the results that would have been obtained had the Business Combination and related transactions actually been completed on the assumed date or for the periods presented, or which may be realized in the future. The pro forma adjustments are based on the information currently available and the assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes. Actual results may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information.

Qell’s warrants are accounted for as a liability and the change in value of its warrants or any other similar derivative liabilities could have a material effect on its financial results.

On April 12, 2021, the SEC’s Acting Director of the Division of Corporation Finance and Acting Chief Accountant together issued guidance regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (the “SEC Guidance”). Specifically, the SEC Guidance focused on certain settlement terms and provisions related to certain partial tender offers following a business combination, which terms are similar to those contained in the warrant agreement governing our warrants. As a result of the SEC Guidance, Qell re-evaluated the accounting treatment of its 12,650,000 public warrants and 7,060,000 private placement warrants, and concluded that the warrants should be classified as a liability measured at fair value, with changes in fair value each period reported in earnings.

Subsequent to the completion of the audit of Qell’s financial statements for the period from August 7, 2020 (inception) through December 31, 2020 and in light of the SEC Guidance, Qell’s management re-evaluated the warrants under Accounting Standards Codification (“ASC”) Subtopic 815-40, Contracts in Entity’s Own Equity. ASC Section 815-40-15 addresses equity versus liability treatment and classification of equity-linked financial instruments, including warrants, and states that a warrant may be classified as a component of equity only if, among other things, the warrant is indexed to the issuer’s common stock. Under

TABLE OF CONTENTS

ASC Section 815-40-15, a warrant is not indexed to the issuer’s common stock if the terms of the warrant require an adjustment to the exercise price upon a specified event and that event is not an input to the fair value of the warrant. Based on management’s revaluation, Qell’s audit committee, in consultation with management and after discussion with its independent registered public accounting firm, concluded that Qell’s warrants are not indexed to its common shares in the manner contemplated by ASC Section 815-40-15 because the holder of the instrument is not an input into the pricing of a fixed-for-fixed option on equity shares. In addition, based on such re-evaluation, Qell’s audit committee, in consultation with management and after discussion with its independent registered public accounting firm, concluded the tender offer provision included in the warrant agreement fails the “classified in shareholders’ equity” criteria as contemplated by ASC Section 815-40-25. Based on the foregoing analysis, Qell should have classified the warrants as derivative liabilities in its previously issued financial statements. Under this accounting treatment, Qell is required to measure the fair value of the warrants at the end of each reporting period and recognize changes in the fair value from the prior period in its operating results for the current period. As a result of the recurring fair value measurement of our warrants and any subsequent changes in fair value from a prior period, Qell’s results of operations in its financial statements may fluctuate quarterly based on factors which are outside of its control. Due to this recurring fair value measurement, Qell expects that it will recognize non-cash gains or losses on its warrants each reporting period and that the amount of such gains or losses could be material.

Qell has identified a material weakness in its internal control over financial reporting as of December 31, 2020. If Qell is unable to develop and maintain an effective system of internal control over financial reporting, it may not be able to accurately report its financial results in a timely manner, which may adversely affect investor confidence in Qell and materially and adversely affect its business and operating results.

Qell’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in the Exchange Act Rule 13a-15(f). Qell’s internal control over financial reporting are designed to provide reasonable assurance to its management and board of directors regarding the preparation and fair presentation of published financial statements. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of Qell’s annual or interim financial statements will not be prevented, or detected and corrected on a timely basis.

Following the issuance of the SEC Guidance, Qell’s audit committee, in consultation with its management and after discussions with its independent registered public accounting firm, concluded that Qell should have classified its warrants as derivative liabilities in its previously issued financial statements, and, for the purposes of properly reflecting such treatment in Qell’s financial statements, it was appropriate to restate Qell’s previously issued audited financial statements as of and for the period from August 7, 2020 (inception) through December 31, 2020 (the “Restatement”). See “— Our warrants are accounted for as a liability and the change in value of our derivative liabilities could have a material effect on our financial results.” As part of such process, Qell’s management, including its principal executive officers and principal financial officer, have evaluated the effectiveness of Qell’s internal control over financial reporting and concluded that it did not maintain effective internal control over financial reporting as of December 31, 2020 because of a material weakness in its internal control over financial reporting solely related to the accounting for the warrants Qell issued in connection with its initial public offering and concurrent private placement. To respond to this material weakness, Qell has devoted, and plans to continue to devote, effort and resources to the remediation and improvement of its internal control over financial reporting. While Qell has processes to identify and apply applicable accounting requirements, Qell plans to enhance these processes, including providing enhanced access to accounting literature and research materials and increased communication among its personnel and third-party professionals with whom it consults regarding complex accounting applications. These elements of Qell’s remediation plan can only be accomplished over time, and it can offer no assurance that these initiatives will ultimately have the intended effects.

If the Business Combination is not consummated and Qell identifies any new material weaknesses in the future, any such newly identified material weakness could limit Qell’s ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of its annual or interim financial statements. In such case, Qell may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in Qell’s financial reporting and its stock price may decline as a result. If the Business Combination is not consummated, Qell cannot assure you that the measures it has taken to date, or any measures it may take in the future, will be sufficient to avoid potential future material weaknesses. If the Business Combination is consummated, Holdco’s internal controls and procedures over financial reporting will instead be established and maintained following Closing, and we can provide no

TABLE OF CONTENTS

assurance that Holdco’s internal controls and procedures over financial reporting will be effective. See “— Risks Associated with Holdco Being a U.S. Public Company — We have identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in the future. Failure to remediate such material weaknesses in the future or to maintain an effective system of internal control could impair our ability to comply with the financial reporting and internal controls requirements for publicly traded companies.”

Qell may face litigation and other risks as a result of the material weakness in its internal control over financial reporting.

As a result of material weakness described above, the Restatement, the change in accounting for the warrants, and other matters raised publicly by the SEC, Qell faces potential for litigation or other disputes which may include, among others, claims under federal and state securities laws, contractual claims or other claims arising from the Restatement and material weaknesses in its internal control over financial reporting and the preparation of its financial statements. As of the date of this proxy statement/prospectus, Qell has no knowledge of any such litigation or dispute. However, Qell can provide no assurance that such litigation or dispute will not arise in the future. Any such litigation or dispute, whether successful or not, could have a material adverse effect on its business, results of operations and financial condition or its ability to complete our proposed Business Combination.

Qell and Lilium will be subject to business uncertainties and contractual restrictions while the Business Combination is pending.

Uncertainty about the effect of the Business Combination on employees, suppliers and customers may have an adverse effect on Lilium and consequently on Qell. These uncertainties may impair Lilium’s ability to attract, retain and motivate key personnel until the Business Combination is completed, and could cause customers and others that deal with Lilium to seek to change existing business relationships with Lilium. Retention of certain employees may be challenging during the pendency of the Business Combination, as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, Holdco’s business following the Business Combination could be negatively impacted. In addition, the Business Combination agreement restricts Lilium from making certain expenditures and taking other specified actions without the consent of Qell until the Business Combination occurs. These restrictions may prevent Lilium from pursuing attractive business opportunities that may arise prior to the completion of the Business Combination.

Neither Qell nor its shareholders will have the protection of any indemnification, escrow, price adjustment or other provisions that allow for a post-closing adjustment to be made to the total Business Combination consideration in the event that any of the representations and warranties made by Lilium in the Business Combination Agreement ultimately proves to be materially inaccurate or incorrect.

The representations and warranties made by Lilium and Qell to each other in the Business Combination Agreement will not survive the consummation of the Business Combination. As a result, Qell and its shareholders will not have the protection of any indemnification, escrow, price adjustment or other provisions that allow for a post-closing adjustment to be made to the total Business Combination consideration if any representation or warranty made by Lilium in the Business Combination Agreement proves to be materially inaccurate or incorrect. Accordingly, to the extent such representations or warranties are incorrect, Qell would have no indemnification claim with respect thereto and its financial condition or results of operations could be adversely affected.

The future exercise of registration rights may adversely affect the market price of Holdco’s ordinary shares.

Certain Holdco shareholders will have registration rights for restricted securities. In connection with the consummation of the Business Combination, Holdco will enter into the Registration Rights Agreement with the Sponsor and certain other shareholders of Holdco, which will provide for customary “demand” and “piggyback” registration rights for certain shareholders. Sales of a substantial number of shares of Holdco Class A Shares pursuant to the resale registration statement in the public market could occur at any time the registration statement remains effective. In addition, certain registration rights holders can request underwritten offerings to sell their securities. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of Holdco Class A Shares.

TABLE OF CONTENTS

Qell will incur significant transaction and transition costs in connection with the Business Combination.

Qell has incurred and expects to incur significant, non-recurring costs in connection with consummating the Business Combination. All expenses incurred in connection with the Business Combination Agreement and the transactions contemplated thereby (including the Business Combination), including all legal, accounting, consulting, investment banking and other fees, expenses and costs, will be for the account of the party incurring such fees, expenses and costs; provided that, Qell’s fees, expenses and costs will be reimbursed by Holdco in the event that the Business Combination completes.

Qell’s transaction expenses as a result of the Business Combination are currently estimated at approximately $45 million, including approximately $13 million in deferred underwriting commissions to the underwriters of the Qell IPO.

Subsequent to consummation of the Business Combination, we may be exposed to unknown or contingent liabilities and may be required to subsequently take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and our share price, which could cause you to lose some or all of your investment.

We cannot assure you that the due diligence conducted in relation to Lilium has identified all material issues or risks associated with Lilium, its business or the industry in which it competes. Furthermore, we cannot assure you that factors outside of Lilium’s and our control will not later arise. As a result of these factors, we may be exposed to liabilities and incur additional costs and expenses and we may be forced to later write-down or write-off assets, restructure our operations, or incur impairment or other charges that could result in our reporting losses. Even if our due diligence has identified certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with our preliminary risk analysis. If any of these risks materialize, this could have a material adverse effect on our financial condition and results of operations and could contribute to negative market perceptions about our securities or Lilium. Additionally, we have no indemnification rights against Lilium under the Business Combination.

Accordingly, any shareholders or warrant holders of Qell who choose to become Holdco shareholders or warrant holders following the Business Combination could suffer a reduction in the value of their shares, warrants and units. Such shareholders or warrant holders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by our directors or officers of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the registration statement or proxy statement/prospectus relating to the Business Combination contained an actionable material misstatement or material omission.

If third parties bring claims against Qell, the proceeds held in the Trust Account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share.

Qell’s placing of funds in the Trust Account may not protect those funds from third-party claims against Qell. Although Qell will seek to have all vendors, service providers (other than Qell’s independent auditors), prospective target businesses or other entities with which Qell does business execute agreements with Qell waiving any right, title, interest or claim of any kind in or to any funds held in the Trust Account for the benefit of Qell’s public shareholders, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the Trust Account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against Qell’s assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the funds held in the Trust Account, Qell’s management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to Qell than any alternative.

Examples of possible instances where Qell may engage a third party that refuses to execute a waiver include the engagement of a third-party consultant whose particular expertise or skills are believed by Qell Management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where Qell Management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with Qell and will not seek recourse against the Trust Account for any reason. Upon redemption of Qell’s public shares, if Qell is unable to complete the Business Combination within the prescribed timeframe, or upon the exercise of a redemption

TABLE OF CONTENTS

right in connection with the Business Combination, Qell will be required to provide for payment of claims of creditors that were not waived that may be brought against Qell within the ten years following redemption. Accordingly, the per-share redemption amount received by Qell’s public shareholders could be less than the $10.00 per share initially held in the Trust Account, due to claims of such creditors.

The Sponsor has agreed that it will be liable to Qell if and to the extent any claims by a vendor for services rendered or products sold to Qell, or a prospective target business with which Qell has discussed entering into a Business Combination Agreement, reduce the amount of funds in the Trust Account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under Qell’s indemnity of the underwriters of the Qell IPO against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. Qell has not independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believes that the Sponsor’s only assets are securities of Qell. The Sponsor may not have sufficient funds available to satisfy those obligations. Qell has not asked the Sponsor to reserve for such eventuality, and therefore, no funds are currently set aside to cover any such obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for a business combination and redemptions could be reduced to less than $10.00 per public share. In such event, Qell may not be able to complete a business combination, and Qell shareholders would receive such lesser amount per share in connection with any redemption of public shares.

Qell’s directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to Qell’s public shareholders.

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.00 per share or (ii) other than due to the failure to obtain such waiver, such lesser amount per share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, and the Sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, Qell’s independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While Qell currently expects that its independent directors would take legal action on its behalf against the Sponsor to enforce its indemnification obligations to Qell, it is possible that Qell’s independent directors in exercising their business judgment may choose not to do so in any particular instance. If Qell’s independent directors choose not to enforce these indemnification obligations, the amount of funds in the Trust Account available for distribution to Qell’s public shareholders may be reduced below $10.00 per share.

If, before distributing the proceeds in the Trust Account to Qell public shareholders, Qell files a bankruptcy petition or an involuntary bankruptcy petition is filed against Qell that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of Qell’s shareholders and the per-share amount that would otherwise be received by Qell’s shareholders in connection with Qell’s liquidation may be reduced.

If, before distributing the proceeds in the Trust Account to Qell public shareholders, Qell files a bankruptcy petition or an involuntary bankruptcy petition is filed against Qell that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in Qell’s bankruptcy estate and subject to the claims of third parties with priority over the claims of Qell’s shareholders. To the extent any bankruptcy claims deplete the Trust Account, the per-share amount that would otherwise be received by Qell’s shareholders in connection with its liquidation may be reduced.

Qell’s public shareholders may be held liable for claims by third parties against Qell to the extent of distributions received by them upon redemption of their public shares.

If Qell is forced to enter into an insolvent liquidation, any distributions received by public shareholders could be viewed as an unlawful payment if it was proved that immediately following the date on which the distribution was made, Qell was unable to pay its debts as they fall due in the ordinary course of business. As a result, a liquidator could seek to recover all amounts received by Qell’s shareholders. Furthermore, Qell’s directors may be viewed as having breached their fiduciary duties to Qell or its creditors and/or may have acted in bad faith, and thereby exposing themselves and Qell to claims, by paying public shareholders

TABLE OF CONTENTS

from the Trust Account prior to addressing the claims of creditors. Qell cannot assure you that claims will not be brought against it for these reasons. Qell and its directors and officers who knowingly and willfully authorized or permitted any distribution to be paid out of Qell’s share premium account while it was unable to pay its debts as they fall due in the ordinary course of business would be guilty of an offense and may be liable to a fine of $18,292.68 and to imprisonment for five years in the Cayman Islands.

If, after Qell distributes the proceeds in the Trust Account to its public shareholders, Qell files a bankruptcy petition or an involuntary bankruptcy petition is filed against Qell that is not dismissed, a bankruptcy court may seek to recover such proceeds, and the members of the Qell Board may be viewed as having breached their fiduciary duties to Qell’s creditors, thereby exposing the members of the Qell Board and Qell to claims of punitive damages.

If, after Qell distributes the proceeds in the Trust Account to its public shareholders, Qell files a bankruptcy petition or an involuntary bankruptcy petition is filed against Qell that is not dismissed, any distributions received by shareholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover all amounts received by Qell’s shareholders. In addition, the Qell Board may be viewed as having breached its fiduciary duty to Qell’s creditors and/or having acted in bad faith, thereby exposing itself and Qell to claims of punitive damages, by paying public shareholders from the Trust Account prior to addressing the claims of creditors.

Because Qell is incorporated under the laws of the Cayman Islands, you may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. federal courts may be limited.

Qell is an exempted company incorporated under the laws of the Cayman Islands. As a result, it may be difficult for Qell public shareholders to effect service of process within the United States upon Qell’s directors or executive officers, or enforce judgments obtained in the United States courts against Qell’s directors or officers.

Qell’s corporate affairs are governed by its amended and restated memorandum and articles of association, the Cayman Islands Companies Act and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of Qell’s directors to Qell under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, the decisions of whose courts are of persuasive authority, but are not binding on a court in the Cayman Islands. The rights of Qell’s shareholders and the fiduciary responsibilities of Qell’s directors under Cayman Islands law are different from what they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a different body of securities laws as compared to the United States, and certain states, such as Delaware, may have more fully developed and judicially interpreted bodies of corporate law. In addition, shareholders of Cayman Islands companies may not have standing to initiate a shareholders derivative action in a federal court of the United States.

Shareholders of Cayman Islands exempted companies like Qell have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of the register of members of these companies. Our directors have discretion under our amended and restated articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

The courts of the Cayman Islands are unlikely (i) to recognize or enforce against Qell judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state, and (ii) in original actions brought in the Cayman Islands, to impose liabilities against Qell predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in

TABLE OF CONTENTS

respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

As a result of all of the above, Qell public shareholders may have more difficulty in protecting their interests in the face of actions taken by Qell management, members of the Qell Board or controlling shareholders of Qell than they would as public shareholders of a United States company.

Qell shareholders may have limited remedies if their shares suffer a reduction in value following the Business Combination.

Any shareholders who choose to remain shareholders following a business combination could suffer a reduction in the value of their shares. Such shareholders are unlikely to have a remedy for such reduction in value, unless they are able to successfully claim that the reduction was due to the breach by Qell’s officers or directors of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the proxy statement relating to a business combination contained an actionable material misstatement or material omission.

If Qell or Holdco is or was a passive foreign investment company, or “PFIC,” there may be material adverse U.S. federal income tax consequences to U.S. Holders of Holdco Class A Shares and Holdco Public Warrants

If Qell or Holdco is or was a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder (as defined below) of Holdco Class A Shares or Holdco Public Warrants, the U.S. Holder may be subject to material adverse U.S. federal income tax consequences and may be subject to additional reporting requirements. It is uncertain whether Qell was treated as a PFIC or Holdco will be treated as a PFIC for U.S. federal income tax purposes. Although Holdco’s PFIC status is determined annually, an initial determination that Qell was a PFIC or that Holdco is a PFIC will generally apply for subsequent years to a U.S. Holder who held Qell Ordinary Shares, Qell Public Warrants, Holdco Class A Shares or Holdco Public Warrants while Qell or Holdco was a PFIC, whether or not Qell or Holdco meets the test for PFIC status in subsequent years. In addition, Holdco’s PFIC status for any subsequent taxable year will not be determinable until after the end of such taxable year. If Holdco determines that it is a PFIC for any taxable year, upon written request, it will endeavor to provide to a U.S. Holder such information as the IRS may require, including a PFIC Annual Information Statement, in order to enable the U.S. Holder to make and maintain a “qualified electing fund” election, but there is no assurance that Holdco will timely provide such required information. There is also no assurance that Holdco will have timely knowledge of its status as a PFIC in the future or of the required information to be provided. U.S. Holders are urged to consult their tax advisors regarding the possible application of the PFIC rules. For a more detailed discussion of the tax consequences of PFIC classification to U.S. Holders, see “Material Tax Considerations — Material U.S. Federal Income Tax Considerations to U.S. Holders — Passive Foreign Investment Company Rules.”

Risks Related to the Redemption

Qell’s amended and restated memorandum and articles of association does not provide a specified maximum redemption threshold, except that in no event will Qell redeem its public shares in an amount that would cause its net tangible assets to be less than $5,000,001, such that Qell is not subject to the SEC’s “penny stock” rules. This minimum net tangible asset amount is also required as an obligation to each party’s obligation to consummate the Business Combination under the Business Combination Agreement. In addition, the Business Combination Agreement provides that each party’s obligation to consummate the Business Combination is conditioned on the amount of cash in the Trust Account (net of any redeemed amounts) together with the Aggregate PIPE Proceeds being at least $450,000,000. As a result, Qell may be able to complete the Business Combination even though a substantial portion of its public shareholders do not agree with the transaction and have redeemed their shares or have entered into privately negotiated agreements to sell their shares to the Sponsor or Qell’s officers, directors, advisors or their affiliates.

TABLE OF CONTENTS

If the Business Combination is not consummated, Qell will not redeem any shares, all Qell Class A Ordinary Shares submitted for redemption will be returned to the holders thereof, and Qell instead may search for an alternate business combination.

If you or a “group” of shareholders of which you are a part are deemed to hold an aggregate of more than 15% of the Qell Class A Ordinary Shares issued in the Qell IPO, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of the Qell Class A Ordinary Shares issued in the Qell IPO.

A public shareholder, together with any of his, her or its affiliates or any other person with whom it is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming in the aggregate his, her or its shares or, if part of such a group, the group’s shares, in excess of 15% of the Qell Class A Ordinary Shares included in the units sold in the Qell IPO. In order to determine whether a shareholder is acting in concert or as a group with another shareholder, Qell will require each public shareholder seeking to exercise redemption rights to certify to Qell whether such shareholder is acting in concert or as a group with any other shareholder. Such certifications, together with other public information relating to share ownership available to Qell at that time, such as Schedule 13D, Schedule 13G and Section 16 filings under the Exchange Act, will be the sole basis on which Qell makes the above-referenced determination. Your inability to redeem any such excess shares will reduce your influence over Qell’s ability to consummate the Business Combination and you could suffer a material loss on your investment in Qell if you sell such excess shares in open market transactions. Additionally, you will not receive redemption distributions with respect to such excess shares if Qell consummates the Business Combination. As a result, you will continue to hold that number of shares aggregating to more than 15% of the shares sold in the Qell IPO and, in order to dispose of such excess shares, would be required to sell your Qell Class A Ordinary Shares in open market transactions, potentially at a loss. There is no assurance that the value of such excess shares will appreciate over time following the Business Combination or that the market price of the Qell Class A Ordinary Shares will exceed the per-share redemption price. Notwithstanding the foregoing, shareholders may challenge Qell’s determination as to whether a shareholder is acting in concert or as a group with another shareholder in a court of competent jurisdiction.

However, Qell’s shareholders’ ability to vote all of their shares (including such excess shares) for or against the Business Combination is not restricted by this limitation on redemption.

There is no guarantee that a shareholder’s decision whether to redeem its shares for a pro rata portion of the Trust Account will put the shareholder in a better future economic position.

There is no assurance as to the price at which a Qell shareholder may be able to sell its public shares in the future following the completion of the Business Combination or any alternative business combination. Certain events following the consummation of any initial business combination, including the Business Combination, may cause an increase in the share price, and may result in a lower value realized now than a shareholder of Qell might realize in the future had the shareholder not redeemed its shares. Similarly, if a shareholder does not redeem its shares, the shareholder will bear the risk of ownership of the public shares after the consummation of any initial business combination, and there can be no assurance that a shareholder can sell its shares in the future for a greater amount than the redemption price set forth in this proxy statement/prospectus. A shareholder should consult the shareholder’s tax and/or financial advisor for assistance on how this may affect his, her or its individual situation.

Qell public shareholders who wish to redeem their shares for a pro rata portion of the Trust Account must, among other things (i) submit a request in writing and (ii) tender their certificates to the Transfer Agent or deliver their shares to the Transfer Agent electronically through the DWAC system at least two business days prior to the General Meeting. In order to obtain a physical stock certificate, a shareholder’s broker and/or clearing broker, DTC and the Transfer Agent will need to act to facilitate this request. Shareholders should generally allot at least two weeks to obtain physical certificates from the Transfer Agent. However, because Qell does not have any control over this process or over the brokers it may take significantly longer than two weeks to obtain a physical stock certificate. If it takes longer than anticipated

TABLE OF CONTENTS

to obtain a physical certificate, shareholders who wish to redeem their shares may be unable to obtain physical certificates by the deadline for exercising their redemption rights and thus will be unable to redeem their shares.

Shareholders electing to redeem their shares will receive their pro rata portion of the Trust Account less franchise and income taxes payable, calculated as of two business days prior to the anticipated consummation of the Business Combination. Please see the section entitled “General Meeting of Qell Shareholders — Redemption Rights” for additional information on how to exercise your redemption rights.

Qell will comply with the proxy rules when conducting redemptions in connection with the Business Combination. Despite Qell’s compliance with these rules, if a public shareholder fails to receive Qell’s tender offer or proxy materials, as applicable, such shareholder may not become aware of the opportunity to redeem its shares. In addition, the proxy materials, as applicable, that Qell will furnish to holders of its public shares in connection with the Business Combination will describe the various procedures that must be complied with in order to validly redeem public shares. In the event that a shareholder fails to comply with these procedures, its shares may not be redeemed.

If Qell is unable to consummate a business combination by October 2, 2022 the public shareholders may be forced to wait beyond such date before redemption from the Trust Account.

If Qell is unable to consummate a business combination by October 2, 2022, Qell will distribute the aggregate amount then on deposit in the Trust Account (less up to $100,000 of the earned interest, net of taxes payable, thereon to pay dissolution expenses), pro rata to the public shareholders by way of redemption and cease all operations, except for the purposes of winding up Qell’s affairs. Any redemption of public shares shall be effected automatically by function of the Qell amended and restated memorandum and articles of association prior to any voluntary winding up. If Qell is required to wind up, liquidate the Trust Account and distribute such amount therein, to the public shareholders pro rata, as part of any liquidation process, such winding up, liquidation and distribution must comply with the applicable provisions of the Cayman Islands Companies Act. In that case, Qell shareholders may be forced to wait beyond the initial 24 months before the redemption proceeds of the Trust Account become available to them and they receive the return of their pro rata portion of the proceeds from the Trust Account. Qell has no obligation to return funds to shareholders prior to the date of the redemption or liquidation, unless it consummates a business combination prior thereto and only then in cases where shareholders have properly sought to redeem their Qell Class A Ordinary Shares. Only upon the redemption or any liquidation will public shareholders be entitled to distributions if Qell is unable to complete a business combination.

Lilium/Holdco Risk Factors

You should carefully review and consider the following risk factors and the other information contained in this proxy statement/prospectus, including the financial statements and notes to the financial statements included herein and the matters addressed in the section entitled “General Information,” in evaluating the Business Combination and the proposals to be voted on at the General Meeting. For purposes of this section, “Lilium”, “we”, “our” or the “Lilium Group” refer to Lilium GmbH, together with its subsidiaries prior to the consummation of the Business Combination; and “Holdco” refers to Lilium N.V. and the Lilium Group after completion of the Business Combination, in each case unless the context otherwise requires. The occurrence of one or more of the events or circumstances described in these risk factors, alone or in combination with other events or circumstances, may adversely affect the ability to complete or realize the anticipated benefits of the Business Combination, and may have a material adverse effect on the business, cash flows, financial condition and results of operations of Holdco following the Business Combination. The risks discussed below may not prove to be exhaustive and are based on certain assumptions which later may prove to be incorrect or incomplete. Holdco, Lilium and Qell may face additional risks and uncertainties that are not presently known to such entity, or that are currently deemed immaterial, which may also impair their business or financial condition.

Risks Related to Lilium’s Operations, Technology and Financial Condition

We have incurred significant losses and expect to incur significant expenses and continuing losses for the foreseeable future, and we may not achieve or maintain profitability.

We have incurred significant operating losses. Our operating losses were €58.2 million and €138.7 million for the years ended December 31, 2019 and 2020, respectively. We expect to continue to incur substantial

TABLE OF CONTENTS

losses during 2021. Our ability to continue as a going concern will depend on the completion of the Business Combination Agreement or our ability to obtain sufficient funding from other sources. Lilium’s consolidated financial statements for the year ended December 31, 2020 do not include any adjustments that might result from the outcome of this uncertainty and have been prepared on a basis that assumes we will continue as a going concern, as described in the notes to Lilium’s consolidated financial statements included elsewhere in this proxy statement/prospectus. We have not yet started commercial operations, making it difficult for us to predict our future operating results, and we believe that we will continue to incur operating losses until at least the time we begin commercial operations. As a result, our losses may be larger than anticipated, and we may not achieve profitability when expected, or at all, and even if we do, we may not be able to maintain or increase profitability.

We expect our operating expenses to increase over the next several years as we complete our aircraft design, build manufacturing sites and agree the commercial matters necessary to launch of our operations. We expect the rate at which we incur losses will be significantly higher for 2021 though at least 2025 as we engage in the following activities:

•

continue to design, certify and produce our Lilium Jet aircraft;

•

engage suppliers in the development of aircraft components and commit capital to serial production of those components;

•

finish building our production capabilities to assemble the major components of our jets in our Munich factory: the propulsion systems, energy system assembly and aircraft integration, as well as the cost associated with outsourcing production of subsystems and commodity components;

•

close relationships with infrastructure providers to build and license our vertiport infrastructure;

•

hire additional employees across development, design, production, marketing, administration and commercialization of our business;

•

engage with third party providers for design, testing, certification and commercialization of our business;

•

build up inventories of parts and components for our jets;

•

further enhance our research and development capacities to continue the work on our jet’s technology, components, hardware and software performance;

•

test and certify the performance and operation of our jets;

•

work with third-party providers to train our pilots, mechanics and technicians in our proprietary jet operation and maintenance;

•

develop and launch our digital platform and customer user interface;

•

develop our sales and marketing activities and develop our vertiport infrastructure; and

•

increase our general and administrative functions to support our growing operations and our responsibilities as a public company.

Because we will incur the costs and expenses from these efforts before we receive any associated revenue, our losses in future periods will be significant. In addition, we may find that these efforts are more expensive than we currently anticipate or that these efforts may not result in the revenue we anticipate, which would further increase our losses. Furthermore, if our future growth and operating performance fail to meet investor or analyst expectations, or if we have future negative cash flow or losses resulting from our investment in acquiring customers or expanding our operations, this could have a material adverse effect on our business, financial condition and results of operations.

The eVTOL market may not continue to develop, eVTOL aircraft may not be adopted by the transportation market, eVTOL aircraft may not be certified by transportation and aviation authorities or eVTOL aircraft may not deliver the expected reduction in operating costs or time savings.

eVTOL aircraft involve a complex set of technologies and are subject to evolving regulations, many of which were originally not intended to apply to electric and/or VTOL aircraft. Before any eVTOL aircraft can fly passengers, manufacturers and operators must receive requisite regulatory approvals, including — but not limited to — aircraft type certificate and certification-related to air service operations (AOC etc.). No

TABLE OF CONTENTS

eVTOL aircraft have passed certification by EASA or the FAA for commercial operations in Europe or the United States, respectively, and there is no assurance that our current serial prototype for the Lilium Jet will receive government certification in a way that is market-viable or commercially successful, in a timely manner or at all. Gaining government certification requires us to prove the performance, reliability and safety of our Lilium Jet, which cannot be assured. In addition, our operations will be subject to national, federal, state and municipal licensing requirements and other regulatory measures in each jurisdiction in which we lease vertiport space, and we may require changes to our proposed vertiport infrastructure to satisfy licensing or regulatory requirements. Any of the foregoing risks and challenges could adversely affect our prospects, business, financial condition and results of operations.

The success of our business depends on the safety and positive perception of our jets, the establishment of strategic relationships, the convenience of our vertiports, and of our ability to effectively market and sell Regional Air Mobility services.

We have not commenced commercial operations, and we expect that our success will be highly dependent on our target customers’ embrace of Regional Air Mobility and eVTOL vehicles, which we believe will be influenced by the public’s perception of the safety, convenience and cost of our Lilium Jets specifically but also of the industry as a whole. As a new industry, the public has low awareness of Regional Air Mobility and eVTOL vehicles, which will require substantial publicity and marketing campaigns in a cost-effective manner to effectively and adequately target and engage our potential customers. If we are unable to demonstrate the safety of our jets, the convenience of our jets, the cost-effectiveness and time-savings of our Regional Air Mobility services as compared with other commuting, goods transportation, airport shuttle, or regional transportation options, our business may not develop as we anticipate it could, and our business, revenue and operations may be adversely affected. Further, our sales growth will depend on our ability to develop relationships with infrastructure providers, airline, other commercial entities, municipalities and regional governments and landowners, which may not be effective in generating anticipated sales, and marketing campaigns can be expensive and may not result in the acquisition of customers in a cost-effective manner, if at all. If conflicts arise with our strategic counterparties, the other party may act in a manner adverse to us and could limit our ability to implement our strategies. Our strategic counterparties may develop, either alone or with others, products or services in related fields that are competitive with our products and services.

We have a limited operating history and face significant challenges to develop, certify, manufacture and launch our services in a new industry, urban and regional air transportation services. Our Lilium eVTOL jet remains in development, and we do not expect to launch commercial services until 2024, at the earliest, if at all.

Lilium was incorporated in 2015, and we are operating in a newly emerging Regional Air Mobility market, which is continuously evolving. We have no experience as an organization in high volume manufacturing of our planned Lilium Jets or operation of a commercially viable Regional Air Mobility service. We cannot assure you that we or our suppliers and other commercial counterparties will be able to develop efficient, cost-efficient manufacturing capability and processes, and reliable sources of component supplies that will enable us to meet the quality, price, engineering, design and production standards, as well as the production volumes, required to successfully produce and maintain Lilium Jets and provide customers with a high-quality customer service across a distributed network of vertiports. Based on our current testing and projections, we believe that we can achieve our business plan and forecasted performance model targets in terms of aircraft range, speed, energy system capacity, payload and noise; however, our Lilium Jet is not yet fully operational, and we might not achieve all of our performance targets, which would materially impact our business plan and results of operations. You should consider our business and prospects in light of the risks and significant challenges we face as a new entrant into a new industry, including, among other things, with respect to our ability to:

•

design and produce safe, reliable and high-quality Lilium Jets and scale that production in a cost-effective manner;

•

obtain the necessary certification and regulatory approvals in a timely manner;

•

build a well-recognized and respected brand;

•

build and maintain a convenient network of vertiports and provide high quality customer service to our customers;

•

establish and expand our customer base;

TABLE OF CONTENTS

•

successfully market our intra-city Regional Air Mobility services and our goods transportation services to commercial customers;

•

properly price our services, and successfully anticipate the take-up rate and usage of such services by our target customers;

•

successfully maintain and service our jets and maintain a good flow of spare parts and qualified technicians;

•

attract, train and maintain pilots, mechanics and technicians trained in our jets and motivate other talented employees to remain with our company;

•

improve and maintain our operational efficiency;

•

maintain a reliable, secure, high-performance and scalable technology infrastructure;

•

predict our future revenues and appropriately budget for our expenses;

•

anticipate trends that may emerge and affect our business;

•

anticipate and adapt to changing market conditions, including technological developments and changes in competitive landscape;

•

secure, protect and defend our intellectual property; and

•

navigate an evolving and complex regulatory environment.

If we fail to adequately address any or all of these risks and challenges, our business may be materially and adversely affected.

Our estimates for the total addressable market for eVTOL Regional Air Mobility regional passenger and goods transport services are based on a number of internal and third-party estimates, including customers who have expressed interest, assumed prices at which we can offer our services, assumed aircraft development, certification and production figures, our ability to manufacture, obtain regulatory approval and certification, and operate our jets, assumed vertiport networks available to us in our target markets, assumed safety protocols and redundancies, our internal processes and general market conditions. While we believe our assumptions and the data underlying our estimates are reasonable, these assumptions and estimates may not be correct and the conditions supporting our assumptions or estimates may change at any time, thereby reducing the predictive accuracy of these underlying factors. As a result, our estimates of the annual total addressable market for our Regional Air Mobility passenger transport and goods transport services, as well as the expected growth rate for the total addressable market, may prove to be incorrect, which could negatively affect our operating revenue, costs, operations and potential profitability.

We may be unable to adequately control the costs associated with our pre-launch operations, and our costs will continue to be significant after we commence operations.

We will require significant capital to develop and grow our business, including designing, developing, testing, certifying and manufacturing our aircraft, building our manufacturing plant, securing leases and contractual arrangements for our vertiports and other commercial activities, educating customers of the safety, efficiency and cost-effectiveness of our services and building our brand. Our research and development expenses were €38.1 million and €90.3 million in 2019 and 2020, respectively, and we expect to continue to incur significant expenses which will impact our profitability, including continuing research and development expenses, manufacturing, maintenance and procurement costs, marketing, customer and payment system expenses, and general and administrative expenses as we scale our operations. In addition, we expect to incur significant costs in connection with operating our services, including scaling out our operations by building and operating a fleet of jets (including, but not limited to pilot salaries, landing fees, jet maintenance and energy costs), training staff on the operation and maintenance of our aircraft, expanding our vertiport network, and promoting our services. Our ability to become profitable in the future will not only depend on our ability to successfully market our services but also our ability to control our costs. If we are unable to cost efficiently design, certify, manufacture, market, operate and service our jets and operations, our margins, profitability and prospects would be materially and adversely affected.

TABLE OF CONTENTS

We may experience difficulties in managing our growth and commercializing our operations.

We expect to experience significant growth in the scope and nature of our manufacturing and service operations. Our ability to manage our operations and future growth will require us to continue to improve our operational, financial and management controls, compliance programs and reporting systems. We are currently in the process of strengthening our compliance programs, including our compliance programs related to internal controls, intellectual property management, privacy and cybersecurity. We may not be able to implement improvements in an efficient or timely manner and may discover deficiencies in existing controls, programs, systems and procedures, which could have an adverse effect on our business, reputation and financial results.

We may be unable to launch our services on the timeline, or with the scope of services, that we are projecting and that form the basis for our financial projections.

We need to resolve significant regulatory, operational, logistical, and other challenges in order to launch our Lilium Jet services. We do not currently have infrastructure in place to operate our services, and such infrastructure may not become available at all or at the times or under conditions we anticipate. Our Lilium Jets have not yet received any EASA or FAA certification/approvals, and we are working through the details of the required airspace, operational authority and other relevant and necessary multinational, federal, national and local government approvals, which are essential to the operation of our services as projected in our financial projections. Any delay in the financing, design, manufacture, and launch of our Lilium Jets, any delay in the receipt of all necessary regulatory approvals and certifications, and any determination by a transportation or aviation authority that we cannot manufacture or provide or otherwise engage in the services as we contemplated and upon which we based our projections could materially damage our brand, business, prospects, financial condition and operating results, and may require us to incur additional costs and created adverse publicity for our business. If we are not able to overcome these challenges, our business, prospects, operating results and financial condition will be negatively impacted and our ability to grow our business will be harmed.

Our business model has yet to be tested or regulatorily approved and any failure to commercialize our strategic plans would have an adverse effect on our operating results and business, harm our reputation and could result in substantial liabilities that exceed our resources.

Any new business will encounter challenges and difficulties, especially a business pioneer operating in a newly emerging market. Many of these challenges will be beyond our control, including substantial risks and expenses to create a new market, set up operations and educate potential customers about a new market. You should consider the likelihood of our success in light of these risks, expenses, complications, delays discussed in these Risk Factors. There is nothing at this time upon which to base an assumption that our business model will prove successful, and we may not be able to generate significant revenue, raise additional capital or operate profitably. We will continue to encounter risks and difficulties frequently experienced by early commercial stage companies, including scaling up our infrastructure and headcount, and may encounter unforeseen expenses, difficulties or delays in connection with our growth. In addition, as a result of the capital-intensive nature of our business, we expect to continue to sustain substantial operating expenses without generating sufficient revenues to cover expenditures. Any investment in our company is therefore highly speculative and could result in the loss of your entire investment.

Our forward-looking operating information and business plan forecast relies in large part upon assumptions and analyses that we have developed. If these assumptions or analyses prove to be incorrect, our actual operating results may be materially different from our forecasted results.

Our management has prepared our projected financial and operating information and business plan, which reflect our current estimates of future performance. Whether our actual operating and financial results and business develops in a way that is consistent with our expectations and assumptions as reflected in our forecasts depends on a number of factors, many of which are outside our control. Our estimates and assumptions may prove inaccurate, causing the actual amount to differ from our estimates. These factors include, but are not limited to, the risk factors described herein and the following factors:

•

our ability to obtain sufficient capital to sustain and grow our business;

•

our effectiveness in managing our costs and our growth;

•

our ability to meet the performance and cost targets of manufacturing and operating out jets;

TABLE OF CONTENTS

•

developing and commercializing, together with our suppliers, the batteries which meet the technological and operational targets to operate our jets in which we can supply at the volumes and costs we need for our production;

•

establishing and maintaining relationships with key providers and suppliers;

•

the timing, cost and ability to obtain the necessary certifications and regulatory approvals;

•

the development of the Regional Air Mobility market and customer demand for our services;

•

our ability to reduce end-user pricing over time to increase demand, address new market segments and develop a significantly broader customer base;

•

the costs and effectiveness of our marketing and promotional efforts;

•

competition for our Lilium Network and Turnkey Enterprise solutions, both from other competitors in the Regional Air Mobility market as well as from traditional ground and air transport options;

•

our ability to retain existing key management, to integrate recent hires and to attract, retain and motivate qualified personnel;

•

the overall strength and stability of domestic and international economies;

•

regulatory, legislative and political changes; and

•

consumer spending habits.

Unfavorable changes in any of these or other factors, most of which are beyond our control, could materially and adversely affect our business, results of operations and financial results. It is difficult to predict our future revenues and appropriately budget for our expenses, and we have limited insight into trends that may emerge and affect our business. If actual results differ from our estimates or we adjust our estimates in future periods, our operating results and financial position could be materially affected.

We anticipate commencing commercial operations with our fully developed Lilium Jet, if regulatorily approved and certified, which remains under development and has yet to complete the testing and certification process. Any delay in completing testing and certification, and any design changes that may be required to be implemented in order to receive certification, would adversely impact our business plan and financial forecasts and our financial condition.

We expect to commence commercial operations in 2024 with a single model of eVTOL jet. We are currently engaged in a rigorous testing and design program that will be required to substantiate our certification process, and we must conduct and analyze our test flight data before we will be cleared to operate with commercial passengers using our eVTOL jet aircraft. Following each flight test, we undertake, we analyze the resulting data and determine whether additional changes to the jet design, propulsion, electronic motor, battery and software systems are required. We are engaged in a process of carefully reviewing and implementing preliminary operating data in order to identify and implementing changes to our prototype model in order to ensure optimal safety protocols, battery efficiency, sufficient redundancies, and maximum load capacities. For example, a fire occurred during post-flight maintenance after a test flight by one of our two prototypes jets in February 2020, resulting in the total loss of our first Phoenix demonstrator. Although Lilium property was damaged, no injuries or casualties resulted from the fire; however, the damage to our Phoenix demonstrator caused significant delays in the testing and analysis as we redesigned the energy system in our next generation demonstrator and addressed safety protocols, as further discussed under “Business of Lilium and Certain Information about Lilium — Safety and Performance”. The prototypes of one of our competitors, Eviation, was also destroyed in a fire in January 2020, reportedly related to a battery system. If incidents like these occur during testing, if our remediation measures and process changes are not successfully implemented or if we experience issues with manufacturing improvements or design, certification and safety, the anticipated launch of our commercial operations could be delayed.

Any delays in the development, certification, manufacture and commercialization of our Lilium Jets and related technology, such as battery technology or electric motors, may adversely impact our business, financial condition and results of operations.

We have previously experienced, and may experience in the future, delays or other complications in the design, certification, manufacture, launch, production, and servicing ramp up of our jets and related

TABLE OF CONTENTS

technology. If further delays arise or recur, if our remediation measures and process changes do not continue to be successful or if we experience issues with planned manufacturing improvements or design and safety, we could experience issues in sustaining the progress towards commercialization or delays in increasing production capacity. If we encounter difficulties in scaling our production or servicing capabilities, if we fail to supply the required batteries from our suppliers which meet the required performance parameters, if our jet technologies and components do not meet our expectations or if we are unable to launch and operate our initial Regional Air Mobility services before our competitors, or if such technologies fail to perform as expected, are inferior to those of our competitors or are perceived as less safe than those of our competitors, we may not be able to achieve our performance targets in aircraft range, speed, payload and noise or launch products on our anticipated timelines, and our business, financial condition and results of operations could be materially and adversely impacted.

Although we hope to be the first to bring eVTOL Regional Air Mobility services to market, our competitors have also displayed eVTOL prototypes and may gain certification and commercialize their vehicles to allow them to enter the market before us.

We face intense competition to be the first to bring our eVTOL Regional Air Mobility services to market, as further discussed under “Business of Lilium and Certain Information about Lilium — Our Competitive Strengths”. Some of our current and potential competitors may have greater financial, technical, manufacturing, regulatory, marketing and other resources than we do, which may allow them to deploy greater resources to the design, certification, development, regulation, manufacturing, promotion, sales, marketing and support of their eVTOL vehicle fleet and customer services. Additionally, some of our competitors may have greater name recognition, larger sales forces, broader customer and industry relationships and other resources than we do. These competitors may also compete with us in recruiting and retaining qualified research and development, sales, marketing and management personnel, as well as in acquiring technologies complementary to, or necessary for, our jets and our customer services, and they may secure more convenient, exclusive leases on vertiports than we are able to secure. These competitors may also secure intellectual property related to eVTOL jets and related services. There has been some consolidation in the industry, with Joby Aviation’s acquisition of Uber Elevate and partnership with Uber in December 2020, and further consolidation may result in even more resources being concentrated in our competitors. We cannot provide assurances that our eVTOL services will be the first to market. Even if our eVTOL Regional Air Mobility services are first to market, we may not receive any competitive advantage or our potential customers may not choose our services over those of our competitors, or over other transportation options, such as helicopters, or terrestrial passenger options like cars, trains, busses or subways or other goods delivery methods such as trucking, van, car or unmanned drones. Further, our competitors may obtain larger scale capital investment than we have access to, and they may benefit from our efforts in developing consumer and community acceptance for eVTOL aircraft, making it easier for them to obtain the permits and authorizations required to operate a service in the markets in which we intend to launch or in other markets.

Any inability to operate our Regional Air Mobility services after commercial launch at our anticipated flight rate, on our anticipated routes or with our anticipated vertiports could adversely impact our business, financial condition and results operations.

Even if we complete the development, certification, manufacture and commercial launch of our Regional Air Mobility operations, we will be dependent on one jet design system and jets that we manufacture. To be successful and satisfy the assumptions in our business plan, we will need to maintain a sufficient service operation rate consisting of a minimum number of flights per day per jet across a distributed vertiport infrastructure, which will be negatively impacted if we are not able to operate our flight services for any reason. We may be unable to operate our anticipated service operation rate for a number of reasons, such as unexpected weather patterns, maintenance issues, pilot error, design and electronic motoring flaws, airway access restrictions, natural disasters, changes in governmental regulations or in the status of our regulatory certifications and approvals or applications or other events that force us to suspend or delay services. At launch, our jets will be certified for Visual Flight Rule conditions, which means that they will have reduced operations under adverse weather conditions such as storms, fog or heavy precipitation, with enhanced certification planned soon after launch. We intend to extend our certification to all-weather capabilities, although we may be unable to do so, and to receive certification, we may incur significant costs to improve the climate resiliency of our jets and our vertiports. Our vertiports in Florida may be located in areas susceptible to hurricanes and sudden storms, as well as related flooding, and our vertiports in Germany may be located in areas prone to freezing and snow storms, the occurrence of any of which could result in costs and loss of revenue. The potential physical effects of climate change, such as increased frequency and

TABLE OF CONTENTS

severity of storms, fog, mist, freezing conditions and other climate-related events, could affect the frequency of our operations and cause delays and cancellations to our services, which would materially impact our operations, public perception and market image and financial results. If we need to replace any components or hardware in our jets, many of which will be bespoke or custom-produced by or for us, there are limited numbers of replacement parts available, some of which have significant lead time associated with procurement or manufacture, so any unplanned failures could result in reduced jet service and significant delays to our planned growth.

Our potential customers may not generally accept the Regional Air Mobility industry or our passenger or goods transport services. If we are unable to convince customers of the convenience of our services and generally provide high quality customer service that will be expected of a premium service, our business and reputation may be materially and adversely affected.

As a vertically-integrated business, we intend to provide our customers with direct customer service at branded and third party-operated vertiports in our passenger Lilium network, including sales, payment, scheduling, on-site service, pre-boarding lounges and post-boarding customer support, as well as first-mile and last-mile integration with airports, train stations, bus terminals and urban transport systems. Some of these systems we intend to operate directly, such as our customer-facing digital platform and user interface, which remains under development and may be difficult to complete with the functionality and usability that we currently intend to provide. We anticipate that other on-site customer services at our vertiports, like security, refreshments and baggage handling, will be carried out through third parties certified by us. We may be unable to integrate these third-party services in our service offering at launch, or at all, at favorable prices, which could reduce the customer appeal of our services. Further, although such third parties may have experience in servicing other transportation services, they will initially have limited experience in servicing our jets and interfacing with our customer portal. Our service arrangements may not adequately address the service requirements of our customers to their satisfaction, or we and our third-party service operators will have sufficient resources to meet these service requirements in a timely manner as the number of vertiports and vertihubs in our network increases. Our business and our brand will be affiliated with these third-party service operators, and we may experience harm to our reputation if these operators provide our customers with poor service, negative publicity, accidents, or safety incidents. Further, if we are unable to establish a widespread vertiport network that complies with applicable laws, our customers’ receptivity to our service, ease of use, and general satisfaction levels could be adversely affected, which in turn could materially and adversely affect our reputation and thus our sales, results of operations, and prospects.

Adverse publicity stemming from any incident involving us or our competitors, or an incident involving any air travel service or unmanned flight based on autonomous technology, could have a material adverse effect on our business, financial condition and results of operations.

Electric aircraft are based on complex technology that requires skilled pilot operation and maintenance. Like any aircraft, they may experience operational or process failures and other problems, including through adverse weather conditions, unanticipated collisions with foreign objects, manufacturing or design defects, pilot error, software malfunctions, cyber-attacks or other intentional acts that could result in potential safety risks. Any actual or perceived safety issues with our jets, other electric aircraft or eVTOL aircraft, unmanned flight based on autonomous technology or the Regional Air Mobility industry generally may result in significant reputational harm to our business, in addition to tort liability, increased safety infrastructure and other costs that may arise. The electric aircraft industry has had several accidents involving prototypes. Our first Phoenix demonstrator was destroyed by a ground-maintenance fire in February 2020; Eviation’s prototype eVTOL vehicle caught fire during testing in January 2020; a small battery-operated plane operated by Avinor and built by Slovenia’s Pipistrel crashed in Norway in August 2019; and an electric-motor experimental aircraft built by Siemens and Hungarian company Magnus crashed in Hungary in May 2018, killing both occupants. We are at risk of adverse publicity stemming from any public incident involving our company, our employees or our brand. If our personnel or one of jets, or the personnel or vehicles of one of our competitors, were to be involved in a public incident, accident or catastrophe, the public perception of the Regional Air Mobility industry or eVTOL vehicles specifically could be adversely affected, resulting in decreased customer demand for services, significant reputational harm or potential legal liability, which could cause a material adverse effect on our sales and service volumes, business and financial condition. Although our insurance partially covered the damage caused by the February 2020 ground-maintenance fire, the insurance we carry may be inapplicable or inadequate to cover any such incident, accident or catastrophe in the future. If our insurance is inapplicable or insufficient to cover any future incidents, we may be forced to bear substantial losses from an incident or accident.

TABLE OF CONTENTS

Our business plans require a significant amount of capital. In addition, our future capital needs may require us to sell additional equity or debt securities that may adversely affect the market price of our shares and dilute our shareholders or introduce covenants that may restrict our operations.

We expect our capital expenditures to continue to be significant in the foreseeable future as we expand our development, certification, production and commercial launch, and that our level of capital expenditures will be significantly affected by customer demand for our services. The fact that we have a limited operating history and are entering a new industry means we have no historical data on the demand for our services. As a result, our future capital requirements may be uncertain and actual capital requirements may be different from those we currently anticipate. We may seek equity or debt financing to finance a portion of our capital expenditures. Such financing might not be available to us in a timely manner or on terms that are acceptable, or at all.

Our ability to obtain the necessary financing to carry out our business plan is subject to a number of factors, including general market conditions and investor acceptance of our industry and business model. These factors may make the timing, amount, terms and conditions of such financing unattractive or unavailable to us. If we are unable to raise sufficient funds, we will have to significantly reduce our spending, delay or cancel our planned activities or substantially change our corporate structure. We might not be able to obtain any funding, and we might not have sufficient resources to conduct our business as projected, both of which could mean that we would be forced to curtail or discontinue our operations.

We may seek to raise such capital through the issuance of additional shares or debt securities with conversion rights (such as convertible bonds and option rights). An issuance of additional shares or debt securities with conversion rights could potentially reduce the market price of our shares, and we currently cannot predict the amounts and terms of such future offerings.

In addition, our future capital needs and other business reasons could require us to sell additional equity or debt securities or obtain a credit facility. The sale of additional equity or equity-linked securities could dilute our shareholders. In addition, such dilution may arise from the acquisition or investments in companies in exchange, fully or in part, for newly issued shares, options granted to our business partners or from the exercise of stock options by our employees in the context of existing or future share option programs or the issuance of shares to employees in the context of existing or future employee participation programs. The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations.

If we cannot raise additional funds when we need or want them, our operations and prospects could be negatively affected.

If we are unable to successfully design and manufacture our jets, our business will be harmed.

We are expanding our prototype manufacturing facility near Munich to full scale manufacturing and production, and we expect to begin low volume production of our Lilium Jet for testing and certification in 2022. We have signed three supply agreements with Toray Industries, Aciturri Aerostructures and Honeywell and term sheets for manufacturing and outsourcing production agreements with dozens of Tier 1 aerospace companies to produce our jet parts and components, and we are in discussions with further 60-70 manufacturing and outsourcing parties, as discussed under “Business — Production Facilities and Manufacturing Strategy”. Many of the parts and components we require will be custom-made for our jets at our production facilities or the production facilities of our outsourcing parties and suppliers; the equipment used to produce these parts and components would be costly to replace and could require substantial lead time to replace and qualify for use. We may not be able to successfully develop commercial-scale manufacturing capabilities internally or supply chain relationships with our intended Tier 1 suppliers. Other parts and components will be off-the-shelf products manufactured for the airline industry and are readily substituted. Our production facilities and the production facilities of our outsourcing parties and suppliers may be harmed or rendered inoperable by natural or man-made disasters, including earthquakes, flooding, fire and power outages, or by health epidemics, such as the COVID-19 pandemic, which may render it difficult or impossible for us to manufacture our jets for some period of time. The inability to manufacture our jets or the backlog that could develop if our production facilities and the production facilities of our outsourcing parties and suppliers are inoperable for even a short period of time may result in delays in our intended launch or scale-out plans or harm our reputation. Although we maintain insurance for damage to our property and the disruption of our business, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, if at all.

TABLE OF CONTENTS

If the Lilium Jets we build fail to perform as expected, our ability to develop, market, and sell our services could be harmed.

Once we commence serial production, our jets may contain defects in design and manufacture that may cause them not to perform as expected or that may require repairs, service outages and design changes. Further, our Lilium Jets may be impacted by various performance factors that could impair customer satisfaction or cause delays or disruptions to our services, such as wind gusts during take-off and landing, turbulent air during flight, foreign object damage, fan stall or wing flutter, overloading, hail and bird strike, sub-optimal battery performance or excessive noise. If our Lilium Jets fail to perform as expected, we may need to delay launch of commercial operations, reduce our roll out plans and commercial expansions or limit the number of flights or geographic scope of our services, which could adversely affect our brand in our target markets and could adversely affect our business, prospects, and results of operations.

Our Lilium Jets require complex software, battery technology and other technology systems that remain in development and need to be commercialized in coordination with our vendors and suppliers to complete serial production. The failure of advances in technology and of manufacturing at the rates and volumes we project may impact our ability to increase the volume of our production or drive down end user pricing.

Our Lilium Jets will use a substantial amount of third-party and in-house software codes and complex hardware to operate. Our software and hardware may contain, errors, bugs or vulnerabilities, and our systems are subject to certain technical limitations that may compromise our ability to meet our objectives. Some errors, bugs or vulnerabilities inherently may be difficult to detect and may only be discovered after the code has been implemented. We have a limited frame of reference by which to evaluate the long-term performance of our software and hardware systems and our jets, and we may be unable to detect and fix any defects in the jets prior to commencing commercial operations. The development and on-going monitoring of such advanced technologies is inherently complex, and we will need to coordinate with our vendors and suppliers in order to complete full-scale production. Our potential inability to develop the necessary software and technology systems may harm our competitive position or delay the certification or manufacture of our jets.

We are relying on third-party suppliers to develop a number of emerging technologies for use in our products, including lithium-ion battery technology. Many of these technologies are already commercially viable, and measurements of our battery supplier have already yielded promising results. However, the final technology of our batteries and other sub-systems is still under development and the design is not yet finalized. The final cell design of our suppliers may not be able to meet the safety, technological, economical or operational requirements to support the regulatory requirements and performance assumed in our business plan.

We are also relyig on third-party suppliers to commercialized these technologies (such as battery cell technology) at the volume and costs we require to launch and ramp-up our production. Our suppliers may not be able to meet the production timing, volume requirements or cost requirements we have assumed in our business plan. Our third party suppliers could face other challenges, such as the lack of raw materials or machinery, the breakdown of tools in production or the malfunctioning of technology as they ramp up production. As a result, our business plan could be significantly impacted, and we may incur significant delays in production and full commercialization, which could adversely affect our business, prospects, and results of operations.

Our Lilium Jets will make use of lithium-ion battery cells, which have been observed to catch fire or vent smoke and flame.

The battery packs within our Lilium Jets will use lithium-ion cells. On rare occasions, lithium-ion cells can rapidly release the energy they contain by venting smoke and flames in a manner that can ignite nearby materials as well as other lithium-ion cells. While the battery pack is designed to contain any single cell’s release of energy without spreading to neighboring cells, a failure of battery packs in our jets could occur or batteries could catch fire during production or testing, which could result in bodily injury or death and could subject us to lawsuits, regulatory challenges or redesign efforts, all of which would be time consuming and expensive and could harm our brand image. Also, negative public perceptions regarding the suitability of lithium-ion cells for automotive applications, the social and environmental impacts of cobalt mining, or any future incident involving lithium-ion cells, such as a vehicle or other fire, could seriously harm our business and reputation.

TABLE OF CONTENTS

We will rely on third-party suppliers and strategic parties for the provision and development of key emerging technologies, components and materials used in our Lilium Jet, such as the lithium-ion batteries that will power the jets, a significant number of which may be single or limited source suppliers. If any of these prospective suppliers or strategic parties choose to not do business with us at all, or insist on terms that are commercially disadvantageous, we may have significant difficulty in procuring and producing our jets, and our business prospects would be harmed

Third-party suppliers and strategic parties will provide key components and technology to the Lilium Jets. Collaborations with strategic parties are necessary to successfully commercialize our existing and future products. If we are unable to identify or enter into agreements with strategic parties for the development of key technology or if such strategic parties insist on terms that are commercially disadvantageous, including for example the ability to freely commercialize jointly owned intellectual property, we may have significant difficulty in procuring and producing our jets or technologies, components or materials used in our jets. The terms of our existing collaboration agreements typically include one or more of the following: joint ownership of the new intellectual property, assignment of the new intellectual property to either us or the collaborator, either exclusive or non-exclusive licenses to the new intellectual property to us or the collaborator and other restrictions on our or our collaborator’s use of developments, such as non-competes and time or milestone limited exclusivity provisions. If we are unable to negotiate exclusivity regarding the technology developed under these collaborations, our competitors may be able to access the technology that is owned, solely or jointly, by our collaborator.

In addition to our collaborations, we will be substantially reliant on our relationships with our suppliers for the parts and components in our jets. If any of these prospective suppliers choose to not do business with us at all, or insist on terms that are commercially disadvantageous, we may have significant difficulty in procuring and producing our jets, and our business prospects would be harmed. If our suppliers experience any delays in providing us with or developing necessary components, or if our suppliers are unable to deliver necessary components in a timely manner and at prices and volumes acceptable to us, we could experience delays in manufacturing or servicing our jets, delivering on our timelines, and launching and scaling up as anticipated, which could have a material adverse effect on our business, prospects and operating results.

While we plan to obtain components from multiple sources whenever possible, we may purchase many of the components used in our Lilium Jets from a single source. While we believe that we may be able to establish alternate supply relationships and can obtain replacement components for our single source components, we may be unable to do so in the short term (or at all) at prices or quality levels that are acceptable to us. In addition, we could experience delays if our suppliers do not meet agreed upon timelines or experience capacity constraints. Any disruption in the supply of components, whether or not from a single source supplier, could temporarily disrupt production or servicing of our jets until an alternative supplier is able to supply the required material. Changes in business conditions, unforeseen circumstances, governmental changes, and other factors beyond our control or which we do not presently anticipate, could also affect our suppliers’ ability to deliver components to us on a timely basis. Any of the foregoing could materially and adversely affect our results of operations, financial condition and prospects.

If any of our suppliers become economically distressed or go bankrupt, we may be required to provide substantial financial support or take other measures to ensure supplies of components or materials, which could increase our costs, affect our liquidity or cause production disruptions.

We expect to purchase various types of equipment, raw materials and manufactured component parts from our suppliers. If these suppliers experience substantial financial difficulties, cease operations, or otherwise face business disruptions, we may be required to provide substantial financial support to ensure supply continuity or would have to take other measures to ensure components and materials remain available. Any disruption could affect our ability to deliver vehicles and could increase our costs and negatively affect our liquidity and financial performance.

We may not succeed in establishing, maintaining and strengthening our brand, which would materially and adversely affect customer acceptance of our services, reducing our anticipated sales, revenue and forecasts.

Our business and prospects heavily depend on our ability to develop, maintain and strengthen the Lilium brand and sell consumers on the safety, convenience and cost-effectiveness of our Regional Air Mobility services. If we are not able to establish, maintain and strengthen our brand, we may lose the opportunity to build a critical mass of customers. Our ability to develop, maintain and strengthen the Lilium

TABLE OF CONTENTS

brand will depend heavily on the success of our marketing efforts. When it launches, we expect the Regional Air Mobility industry to be intensely competitive, with a strong first-mover advantage, and we may not be the first to launch our services or we may be unsuccessful in building, maintaining and strengthening our brand. If we do not develop and maintain a strong brand, our business, prospects, financial condition and operating results will be materially and adversely impacted.

We are highly dependent on the services of our four founders.

We are highly dependent on the services of our four founders, as described in “Business of Lilium and Certain Information about Lilium — Lilium’s History”, who will be significant shareholders in New Lilium. Our founders are the source of many, if not most, of the ideas and execution driving Lilium. If any of our founders were to discontinue their service to Lilium due to death, disability or any other reason, we would be significantly disadvantaged.

Our business depends substantially on the continuing efforts of our key employees and qualified personnel, and we will require experienced pilots and qualified mechanics to operate and service our Lilium Jets; our operations may be severely disrupted if we lose their services.

Our success depends substantially on the continued efforts of our key employees and qualified personnel, and our operations may be severely disrupted if we lost their services. As we build our brand and become more well known, the risk that competitors or other companies may poach our talent increases. The failure to attract, integrate, train, motivate and retain these personnel could seriously harm our business and prospects.

Throughout the aviation industry, there is a shortage of trained pilots and qualified aircraft mechanics. Our services will depend on finding third parties to recruit and train pilots qualified to operate our Lilium Jets and mechanics qualified to perform the requisite maintenance activities, for which we will compete with airlines and other air mobility and transportation services, some of which will offer wages or benefit packages exceeding ours. We intend to work with third parties to train our pilots, mechanics and technicians in our proprietary jet operation and maintenance; however, if we are unable to hire, train, and retain qualified pilots and qualified mechanics, our business could be harmed, and we may be unable to implement our growth plans.

Our business may be adversely affected by labor and union activities.

Although none of our employees are currently represented by a labor union, it is common throughout the aircraft industry generally for many employees at aircraft companies to belong to a union, which can result in higher employee costs and increased risk of work stoppages. We may also directly and indirectly depend upon other companies with unionized work forces, such as parts suppliers and trucking and freight companies, and work stoppages or strikes organized by such unions could have a material adverse impact on our business, financial condition or operating results.

We face risks related to health epidemics, including the recent COVID-19 pandemic.

We face various risks related to public health issues, including epidemics, pandemics, and other outbreaks, including the recent pandemic of respiratory illness caused by COVID-19. The impact of COVID-19, including changes in consumer and business behavior, unease with shared transport, pandemic fears and market downturns, and restrictions on business and individual activities, has created significant volatility in the global economy and led to reduced economic activity. The spread of COVID-19 has also created a disruption in the manufacturing, delivery and overall supply chain of all manufacturers and suppliers and has led to a global decrease in personal and business travel around the world.

The pandemic has resulted in government authorities implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, stay-at-home or shelter-in-place orders, and business shutdowns. These measures may adversely impact our employees, our ability to provide our services, and the operations of our customers, suppliers, and business partners, and may negatively impact our sales and marketing activities. In addition, many aspects of our research and development activities cannot be conducted remotely. These measures by government authorities may remain in place for a significant period of time and they are likely to continue to adversely affect our manufacturing plans, sales and marketing activities, business and results of operations.

The spread of COVID-19 has caused us to modify our business practices (including employee travel, recommending that all non-essential personnel work from home and reduction of physical participation in

TABLE OF CONTENTS

collaboration and development activities), and we may take further actions as may be required by government authorities or that we determine is in the best interests of our employees, customers, suppliers, vendors and business partners. There is no certainty that such actions will be sufficient to mitigate the risks posed by the virus or otherwise be satisfactory to government authorities. If significant portions of our workforce are unable to work effectively, including due to illness, quarantines, social distancing, government actions or other restrictions in connection with the COVID-19 pandemic, our operations will be impacted.

The extent to which the COVID-19 pandemic impacts our business, prospects and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including the duration and spread of the pandemic, its severity, the actions to contain the virus or treat its impact, restrictions on shared or air transport, and how quickly and to what extent normal economic and operating activities can resume. Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our business as a result of its global economic impact, including any recession that has occurred or may occur in the future.

Specifically, difficult macroeconomic conditions, such as decreases in discretionary travel, per capita income and level of disposable income, increased and prolonged unemployment, or a decline in consumer confidence as a result of the COVID-19 pandemic could have a material adverse effect on the demand for our services. Under difficult economic conditions, potential customers may seek to reduce spending by forgoing our Regional Air Mobility services.

There are no comparable recent events that may provide guidance as to the effect of the spread of COVID-19 and a pandemic, and, as a result, the ultimate impact of the COVID-19 pandemic or a similar health epidemic is highly uncertain.

Failure of information security and privacy concerns could subject us to penalties, damage our reputation and brand, and harm our business and results of operations.

We expect to face significant challenges with respect to information security and privacy, including the storage, transmission and sharing of confidential information. We will transmit and store confidential and private information of our customers, such as personal information, including names, accounts, user IDs and passwords, and payment or transaction related information.

We intend to adopt strict information security policies and deploy advanced measures to implement the policies, including, among others, advanced encryption technologies. However, advances in technology, an increased level of sophistication of our services, an increased level of expertise of hackers, new discoveries in the field of cryptography or others can still result in a compromise or breach of the measures that we use. If we are unable to protect our systems, and hence the information stored in our systems, from unauthorized access, use, disclosure, disruption, modification or destruction, such problems or security breaches could cause a loss, give rise to our liabilities to the owners of confidential information or even subject us to fines and penalties. In addition, complying with various laws and regulations could cause us to incur substantial costs or require that we change our business practices, including our data practices, in a manner adverse to our business.

In addition, we will need to comply with increasingly complex and rigorous regulatory standards enacted to protect business and personal data in the United States, Europe and elsewhere. For example, the European Union adopted the General Data Protection Regulation (“GDPR”), which became effective on May 25, 2018 and the State of California adopted the California Consumer Privacy Act of 2018 (“CCPA”); additional U.S. states are likely to adopt measures similar to the CCPA in the near term. Both the GDPR and the CCPA impose additional obligations on companies regarding the handling of personal data and provides certain individual privacy rights to persons whose data is stored. Compliance with existing, proposed and recently enacted laws (including implementation of the privacy and process enhancements called for under the GDPR) and regulations can be costly; any failure to comply with these regulatory standards could subject us to legal and reputational risks.

Compliance with any additional laws and regulations could be expensive and may place restrictions on the conduct of our business and the manner in which we interact with our customers. Any failure to comply with applicable regulations could also result in regulatory enforcement actions against us, and misuse of or failure to secure personal information could also result in violation of data privacy laws and regulations, proceedings against us by governmental entities or others, and damage to our reputation and credibility, and could have a negative impact on revenues and profits.

TABLE OF CONTENTS

Significant capital and other resources may be required to protect against information security breaches or to alleviate problems caused by such breaches or to comply with our privacy policies or privacy-related legal obligations. The resources required may increase over time as the methods used by hackers and others engaged in online criminal activities are increasingly sophisticated and constantly evolving. Any failure or perceived failure by us to prevent information security breaches or to comply with privacy policies or privacy-related legal obligations, or any compromise of security that results in the unauthorized release or transfer of personally identifiable information or other customer data, could cause our customers to lose trust in us and could expose us to legal claims. Any perception by the public that online transactions or the privacy of user information are becoming increasingly unsafe or vulnerable to attacks could inhibit the growth of online retail and other online services generally, which may reduce the number of orders we receive.

We are subject to cybersecurity risks to our operational systems, security systems, infrastructure, integrated software in our aircraft and customer data processed by us or third-party vendors.

We are at risk for interruptions, outages and breaches of the following systems, which are either owned by us or operated by our third-party vendors or suppliers:

•

operational systems, including business, financial, accounting, product development, data processing or production processes;

•

facility security systems;

•

aircraft technology including powertrain and avionics and flight control software;

•

the integrated software in our aircraft;

•

customer data; or

•

digital platform.

The occurrence of any such incident could disrupt our operational systems, result in loss of intellectual property, trade secrets or other proprietary or competitively sensitive information, compromise personal information of customers, employees, suppliers, or others, jeopardize the security of our facilities or affect the performance of in-product technology and the integrated software in our jets.

Moreover, there are inherent risks associated with developing, improving, expanding and updating our current systems, such as the disruption of our data management, procurement, production execution, finance, supply chain and sales and service processes. These risks may affect our ability to manage our data and inventory, procure parts or supplies or manufacture, deploy, deliver and service our aircraft, adequately protect our intellectual property or achieve and maintain compliance with, or realize available benefits under, applicable laws, regulations and contracts. We cannot be sure that these systems upon which we rely, including those of our third-party vendors or suppliers, will be effectively implemented, maintained or expanded as planned. If these systems do not operate as we expect them to, we may be required to expend significant resources to make corrections or find alternative sources for performing these functions.

Any unauthorized access to or control of our jets or their systems or any loss of data could result in legal claims or proceedings. In addition, regardless of their veracity, reports of unauthorized access to our jets, their systems or data, as well as other factors that may result in the perception that our jets, their systems or data are capable of being “hacked,” could negatively affect our brand and harm our business, prospects, financial condition and operating results.

We face risks related to natural disasters, health epidemics and other outbreaks, which could significantly disrupt our operations.

Our manufacturing or customer service facilities or operations could be adversely affected by events outside of our control, such as natural disasters, wars, health epidemics like COVID-19, and other calamities. Although we have servers that are hosted in an offsite location, our backup system does not capture data on a real-time basis, and we may be unable to recover certain data in the event of a server failure. We cannot assure you that any backup systems will be adequate to protect us from the effects of fire, floods, typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks or similar events. Any of the foregoing events may give rise to interruptions, breakdowns, system failures, technology platform failures or internet failures, which could cause the loss or corruption of data or malfunctions of software or hardware as well as adversely affect our ability to provide services.

Risks Related to Lilium’s Intellectual Property

We may not be able to prevent others from unauthorized use of our intellectual property, which could harm our business and competitive position.

We may not be able to prevent others from unauthorized use of our intellectual property, which could harm our business and competitive position. We rely on a combination of patents, trade secrets (including know-how), employee and third-party nondisclosure agreements, copyrights, trademarks, intellectual property licenses, and other contractual rights to establish and protect our rights in our technology. Despite our efforts to protect our proprietary rights, third parties may attempt to copy or otherwise obtain and use our intellectual property or seek court declarations that they do not infringe upon our intellectual property rights or those rights are not enforceable. Monitoring unauthorized use of our intellectual property is difficult and costly, and the steps we have taken or will take are aimed to prevent misappropriation. From time to time, we may have to resort to litigation to enforce our intellectual property rights, which could result in substantial costs and diversion of our resources, including significant amounts of time from our key executives and management, and may not have the desired outcome.

Patent, trademark, and trade secret laws vary significantly throughout the world. Some countries do not protect intellectual property rights to the same extent as do the laws of the United States and European Union. Therefore, we may not be able to secure certain intellectual property rights in some jurisdictions, and our intellectual property rights may not be as strong or as easily enforced outside of the United States and the European Union. Failure to adequately protect our intellectual property rights could result in our competitors offering similar products, potentially resulting in the loss of some of our competitive advantage and a decrease in our revenue which, would adversely affect our business, prospects, financial condition and operating results.

Our patent applications may not issue as patents, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours.

We cannot be certain that we are the first inventor of the subject matter to which we have filed or plan to file a particular patent application, or if we are the first party to file such a patent application. If another party has filed a patent application for the same subject matter as we have, or similar subject matter is otherwise publicly disclosed, we may not be entitled to the protection sought by the patent application. Further, the scope of protection of issued patent claims is often difficult to determine. As a result, we cannot be certain that the patent applications that we file will issue, or that our issued patents will afford protection against competitors with similar technology or will cover certain aspects of our products. In addition, our competitors may design around our issued patents, which may adversely affect our business, prospects, financial condition or operating results.

As our patents may expire and may not be extended, our patent applications may not be granted and our patent rights may be contested, circumvented, invalidated or limited in scope, our patent rights may not protect us effectively. In particular, we may not be able to prevent others from developing or exploiting competing technologies.

We cannot assure you that we will be granted patents pursuant to our pending applications or those we plan to file in the future. Even if our patent applications succeed and we are issued patents in accordance with them, these patents could be contested, circumvented or invalidated in the future. In addition, the rights granted under any issued patents may not provide us with meaningful protection or competitive advantages. The claims under any patents that issue from our patent applications may not be broad enough to prevent others from developing technologies that are similar or that achieve results similar to ours. The intellectual property rights of others could also bar us from licensing and exploiting any patents that issue from our pending applications. Numerous patents and pending patent applications owned by others exist in the fields in which we have developed and are developing our technology. These patents and patent applications might have priority over our patent applications and could result in refusal of or invalidation our patent applications . Finally, in addition to those who may claim priority, any of our existing or pending patents may also be challenged by others on the basis that they are otherwise invalid or unenforceable.

We may need to defend ourselves against patent or trademark infringement claims, which may be time-consuming and would cause us to incur substantial costs.

Companies, organizations, or individuals, including our competitors, may hold or obtain patents, trademarks or other proprietary rights that would prevent, limit or interfere with our ability to make, use,

TABLE OF CONTENTS

develop, sell, leasing or market our vehicles or components, which could make it more difficult for us to operate our business. From time to time, we may receive communications from holders of patents (including non-practicing entities or other patent licensing organizations), trademarks or other intellectual property regarding their proprietary rights. Companies holding patents or other intellectual property rights may bring suits alleging infringement of such rights or otherwise assert their rights and urge us to take licenses. Our applications and uses of trademarks relating to our design, software or artificial intelligence technologies could be found to infringe upon existing trademark ownership and rights. In addition, if we are determined to have infringed upon a third party’s intellectual property rights, we may be required to do one or more of the following:

•

cease manufacturing our jets, or discontinue use of certain components in our jets, or offering services that incorporate or use the challenged intellectual property;

•

pay substantial damages;

•

seek a license from the holder of the infringed intellectual property right, which license may not be available on reasonable terms, or at all;

•

redesign our jets or other customer service offerings; or

•

establish and maintain alternative branding for our jets or services.

In the event of a successful claim of infringement against us and our failure or inability to obtain a license to the infringed technology or other intellectual property right, our business, prospects, operating results and financial condition could be materially and adversely affected. In addition, any litigation or claims, whether or not valid, could result in substantial costs, negative publicity and diversion of resources and management attention.

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our employees’ former employers.

Many of our employees were previously employed by other aeronautics, aircraft or transportation companies or by suppliers to these companies. We may be subject to claims that we or these employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of our former employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key personnel or our work product could hamper or prevent our ability to commercialize our products, which could severely harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and demand on management resources.

Risks Related to the Regulatory Environment in which Lilium Operates

We are subject to substantial regulation and unfavorable changes to, or our failure to comply with, these regulations could substantially harm our business and operating results.

Our eVTOL jets and the operation of our Regional Air Mobility services by us or in certain jurisdictions by our local AOCs will be subject to substantial regulation in the jurisdictions in which we intend our eVTOL jets to operate. We expect to incur significant costs in complying with these regulations. Regulations related to the eVTOL industry, including aircraft certification, production certification, passenger operation, flight operation, airspace operation, security regulation and vertiport regulation are currently evolving, and we face risks associated with the development and evolution of these regulations.

Our jets must be certified with the FAA and EASA as a light aircraft, as further discussed under “Business — Certification”. Operating our jets in the U.S. and Europe and providing our passenger and goods transportation services must comply with U.S. and European laws, regulations, safety standards, and customer service regulations. Rigorous testing and the use of approved materials and equipment are among the requirements for achieving certification. Our failure to obtain or maintain certification for our jets or infrastructure would have a material adverse effect on our business and operating results. In addition to obtaining and maintaining certification of our jets, we and our third party air carriers will need to obtain and maintain operational authority necessary to provide our envisioned Regional Air Mobility services. A transportation or aviation authority may determine that we and/or our third party air carriers cannot manufacture, provide, or otherwise engage in the services as we contemplated and upon which we based our projections. The inability to implement our envisioned Regional Air Mobility services could materially and adversely affect our results of operations, financial condition, and prospects.

TABLE OF CONTENTS

To the extent the laws change, our jets and our Regional Air Mobility services may not comply with applicable American, European, international, federal, state or local laws, which would have an adverse effect on our business. Compliance with changing regulations could be burdensome, time consuming, and expensive. To the extent compliance with new regulations is cost prohibitive, our business, prospects, financial condition and operating results would be adversely affected.

When we expand beyond the United States and the European Union, such as into China, there will be Chinese laws and regulations we must comply with, and there may be laws and regulations in other jurisdictions we have not yet entered or laws we are unaware of in jurisdictions we have entered that may restrict our operations or business practices or that are difficult to interpret and change rapidly. Continued regulatory limitations and other obstacles interfering our business operations could have a negative and material impact on our business, prospects, financial condition and results of operations.

Third-party air carriers will operate our Regional Air Mobility services in the U.S. and Europe using the Lilium Jets. These third-party air carriers are subject to substantial regulation and laws, and unfavorable changes to, or the third-party air carriers’ failure to comply with, these regulations and/or laws could substantially harm our business and operating results.

Non-U.S. citizen air carriers cannot engage in air transportation services within the U.S. Accordingly, our strategy for service offerings in the U.S. and the European markets involves strategic relationships with third-party U.S. citizen (as “citizen of the United States” is defined in 49 U.S.C. § 40102(a)(15)) or EU air carriers, respectively, which will be responsible for providing the aircraft services using the Lilium Jets. These third-party air carriers are subject to substantial regulation and laws, and unfavorable changes to, or the third-party air carriers’ failure to comply with, these regulations or laws could substantially harm our business and operating results. Further, although third-party air carriers may have experience in providing air transportation services, they will initially have limited experience in operating our Lilium Jets. Our arrangements with third-party air carriers may not adequately address the operating requirements of our customers to their satisfaction. Given that our business and our brand will be affiliated with these third-party air carriers, we may experience harm to our reputation if these third-party air carriers provide customers with poor service, receive negative publicity, or experience accidents or safety incidents. Further, under U.S. law and the policy of the U.S. Department of Transportation, U.S. citizens must have actual control of U.S. air carriers, and thus there are limits on our ability to exercise control over such U.S. air carriers. Any determination by a transportation or aviation authority that we cannot provide or otherwise engage in the services as we contemplated and upon which we based our projections could materially affect the services we intend to offer and could adversely affect our results of operations, financial condition, business and prospects.

We are or will be subject to anti-corruption, anti-bribery, anti-money laundering, financial and economic sanctions and similar laws, and non-compliance with such laws can subject us to administrative, civil and criminal fines and penalties, collateral consequences, remedial measures and legal expenses, all of which could adversely affect our business, results of operations, financial condition and reputation.

We are or will be subject to anti-corruption, anti-bribery, anti-money laundering, financial and economic sanctions and similar laws and regulations in various jurisdictions in which we conduct or in the future may conduct activities, including the U.S. Foreign Corrupt Practices Act (“FCPA”), European anti-bribery and corruption laws, and other anti-corruption laws and regulations. The FCPA and European anti-bribery and corruption laws prohibit us and our officers, directors, employees and business partners acting on our behalf, including agents, from corruptly offering, promising, authorizing or providing anything of value to a “foreign official” for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. The FCPA also requires companies to make and keep books, records and accounts that accurately reflect transactions and dispositions of assets and to maintain a system of adequate internal accounting controls. A violation of these laws or regulations could adversely affect our business, results of operations, financial condition and reputation. Our policies and procedures designed to ensure compliance with these regulations may not be sufficient and our directors, officers, employees, representatives, consultants, agents, and business partners could engage in improper conduct for which we may be held responsible.

Non-compliance with anti-corruption, anti-bribery, anti-money laundering or financial and economic sanctions laws could subject us to whistleblower complaints, adverse media coverage, investigations, and severe administrative, civil and criminal sanctions, collateral consequences, remedial measures and legal expenses, all of which could materially and adversely affect our business, results of operations, financial

TABLE OF CONTENTS

condition and reputation. In addition, changes in economic sanctions laws in the future could adversely impact our business and investments in its shares.

We will be subject to governmental export and import control laws and regulations as we expand our suppliers and commercial operations outside the U.S. and Europe.

Our Lilium Jets will be subject to export control and import laws and regulations, which must be made in compliance with these laws and regulations. For example, we may require licenses to import or export our jets, components or technologies to our production facilities and may experience delays in obtaining the requisite licenses to do so. Audits in connection with the application for licenses may increase areas of noncompliance that could result in delays or additional costs. If we fail to comply with these laws and regulations, we and certain of our employees could be subject to additional audits, substantial civil or criminal penalties, including the possible loss of export or import privileges, fines, which may be imposed on us and responsible employees or managers and, in extreme cases, the incarceration of responsible employees or managers.

Risks Associated with Holdco Being a U.S. Public Company

We will need to improve our operational and financial systems to support our expected growth, increasingly complex business arrangements, and rules governing revenue and expense recognition and any inability to do so will adversely affect our billing and reporting.

To manage the expected growth of our operations and increasing complexity, we will need to improve our operational and financial systems, procedures, and controls and continue to increase systems automation to reduce reliance on manual operations. Any inability to do so will affect our manufacturing operations, customer billing and reporting. Our current and planned systems, procedures and controls may not be adequate to support our complex arrangements and the rules governing revenue and expense recognition for our future operations and expected growth. Delays or problems associated with any improvement or expansion of our operational and financial systems and controls could adversely affect our relationships with our customers, cause harm to our reputation and brand and could also result in errors in our financial and other reporting. We expect that complying with these rules and regulations will substantially increase our legal and financial compliance costs and will make some activities more time-consuming and costly. The increased costs will increase our net loss. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements.

We have identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in the future. Failure to remediate such material weaknesses in the future or to maintain an effective system of internal control could impair our ability to comply with the financial reporting and internal controls requirements for publicly traded companies.

As a U.S. public company, we will operate in an increasingly demanding regulatory environment, which requires us to comply with the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), Nasdaq regulations, SEC rules and regulations, expanded disclosure requirements, accelerated reporting requirements and more complex accounting rules. Company responsibilities required by the Sarbanes-Oxley Act include establishing corporate oversight and adequate internal control over financial reporting and disclosure controls and procedures. Effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent financial fraud.

In connection with the audit of our consolidated financial statements, we identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses relate to (i) lack of consistent and proper application of accounting processes and procedures, defined control processes and segregation of duties, (ii) insufficient design, implementation and operating effectiveness of information technology general controls for information systems that are significant to the preparation of our financial statements, (iii) lack of review and supervision and (iv) insufficient resources with an appropriate level of technical accounting and SEC reporting expertise.

We are in the process of designing and implementing measures to improve our internal control over financial reporting to remediate the material weaknesses, including by implementing new information technology and systems for the preparation of the financial statements, implementing additional review

TABLE OF CONTENTS

procedures within our accounting and finance department, hiring additional staff and engaging external accounting experts to support improving our accounting processes and procedures and supplement our internal resources in our computation processes. While we are designing and implementing measures to remediate the material weaknesses, we cannot predict the success of such measures or the outcome of our assessment of these measures at this time. These measures may not remediate the deficiencies in internal control or prevent additional material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Our failure to implement and maintain effective internal control over financial reporting could result in errors in our financial statements that may lead to a restatement of our financial statements or cause us to fail to meet our reporting obligations.

We anticipate that the process of building our accounting and financial functions and infrastructure will result in substantial costs, including significant additional professional fees and internal costs. Any disruptions or difficulties in implementing or using such a system could adversely affect our controls and harm our business. Moreover, such disruption or difficulties could result in unanticipated costs and diversion of management’s attention.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to maintain proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, investors could lose confidence in our reported financial information and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities.

Our management has limited experience in operating a U.S. public company.

Our management have limited experience in the management of a U.S. public or European listed company. Our management team may not successfully or effectively manage our transition to a U.S. public company that will be subject to significant regulatory oversight and reporting obligations under federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted to the management and growth of the combined company. We may not have adequate personnel with the appropriate level of knowledge, experience, and training in the accounting policies, practices or internal controls over financial reporting required of U.S. public companies. The development and implementation of the standards and controls necessary for the combined company to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. It is possible that we will be required to expand our employee base and hire additional employees to support our operations as a public company, which will increase our operating costs in future periods.

Our failure to meet Nasdaq’s continued listing requirements could result in a delisting of our shares.

If, after listing, we fail to satisfy Nasdaq’s continued listing requirements, such as the corporate governance requirements or the minimum closing bid price requirement, Nasdaq may take steps to delist our shares. Such a delisting would likely have a negative effect on the price of our shares and would impair your ability to sell or purchase our shares when you wish to do so. In the event of a delisting, we can provide no assurance that any action taken by it to restore compliance with listing requirements would allow our shares to become listed again, stabilize the market price or improve the liquidity of our shares, prevent our shares from dropping below Nasdaq’s minimum bid price requirement or prevent future non-compliance with Nasdaq’s listing requirements.

If securities or industry analysts do not publish research or reports about our business or publish negative reports about our business, our share price and trading volume could decline.

The trading market for our shares will depend on the research and reports that securities or industry analysts publish about us or our business. Currently, we do not have any analyst coverage and may not obtain analyst coverage in the future. In the event we obtain analyst coverage, we will not have any control over such analysts. If one or more of the analysts who cover Lilium downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of Lilium or fail to regularly publish reports on Lilium we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

TABLE OF CONTENTS

We will be an “emerging growth company,” and our reduced SEC reporting requirements may make our shares less attractive to investors.

We will be an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). We will remain an “emerging growth company” until the earliest to occur of (i) the last day of the fiscal year (a) following the fifth anniversary of the closing of the Business Combination, (b) in which we have total annual gross revenue of at least $1.07 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of Holdco Shares held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (ii) the date on which we issued more than $1.0 billion in non-convertible debt during the prior three-year period. We intend to take advantage of exemptions from various reporting requirements that are applicable to most other public companies, such as an exemption from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring our independent registered public accounting firm provide an attestation report on the effectiveness of our internal control over financial reporting and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our shares less attractive because we intend to rely on certain of these exemptions and benefits under the JOBS Act. If some investors find our shares less attractive as a result, there may be a less active, liquid and/or orderly trading market for our shares and the market price and trading volume of our shares may be more volatile and decline significantly.

As a foreign private issuer, we will be exempt from a number of rules under the U.S. securities laws and will be permitted to file less information with the SEC than a U.S. domestic public company, which may limit the information available to our shareholders.

We will be a foreign private issuer, as such term is defined in Rule 405 under the Securities Act. As a foreign private issuer, we will not be subject to all of the disclosure requirements applicable to public companies organized within the United States. For example, we will be exempt from certain rules under the Exchange Act that regulate disclosure obligations and procedural requirements related to the solicitation of proxies, consents or authorizations applicable to a security registered under the Exchange Act, including the U.S. proxy rules under Section 14 of the Exchange Act. As long as we are a foreign private issuer, we will not be required to obtain shareholder approval for certain dilutive events, such as the establishment or material amendment of certain equity-based compensation plans, we will not be required to provide detailed executive compensation disclosure in our periodic reports, and we will be exempt from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. In addition, our officers and directors will be exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of its securities.

While we intend to submit quarterly interim consolidated financial data to the SEC under cover of the SEC’s Form 6-K, we will not be required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. domestic public companies and will not be required to file quarterly reports on Form 10-Q or current reports on Form 8-K under the Exchange Act.

Also, as a foreign private issuer, we will be permitted to follow home country practice in lieu of certain Nasdaq corporate governance rules, as discussed under “Description of Holdco Securities — Periodic Reporting Under U.S. Securities Law”, including those that require listed companies to have a majority of independent directors (although all of the members of the audit committee must be independent under the Exchange Act) and independent director oversight of executive compensation, nomination of directors and corporate governance matters; have regularly scheduled executive sessions with only independent directors; and adopt and disclose a code of ethics for directors, officers and employee. Accordingly, our shareholders may not have the same protections afforded to shareholders of listed companies that are subject to all of the applicable corporate governance requirements.

Risks Related to Taxes

Holdco’s tax residency might change if Germany would ratify the MLI and change its provisional election on the corporate residence tie-breaker.

Holdco’s sole tax residency in Germany for purposes of the convention between Germany and the Netherlands for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income (the “German-Dutch tax treaty”) is subject to the application of the provisions on tax residency as

TABLE OF CONTENTS

stipulated in the German-Dutch tax treaty as effective as of the date of this proxy statement/prospectus. However, among others, Germany and the Netherlands entered into a Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (“MLI”). The MLI operates to amend bilateral tax treaties between participating states, provided there is a match between certain options made by the relevant states. The MLI provides, amongst others, for an amendment of relevant treaty rules regarding tax residency for purposes of relevant tax treaties. According to its elections, the Netherlands applies such deviating rules on tax residency, i.e., it did not opt out. With regard to Germany, provisional statements made at the time of signing the MLI indicate that it is intended to opt-out of the application of such provisions. However, given that the MLI has to date not been ratified in Germany and the options provided for in the MLI remain subject to discussion, it cannot be ruled out that Germany ultimately opts to amend the current rules regarding tax residency in line with the option exercised by the Netherlands. If Germany changed its provisional view on the election, the MLI rules on tax residency would become applicable to the German-Dutch tax treaty. In this case, the competent authorities of the Netherlands and Germany shall endeavor to determine by mutual agreement the sole tax residency of Holdco. During the period in which a mutual agreement between both states is absent, Holdco may not be entitled to any relief or exemption from tax provided by the German-Dutch tax treaty. During such period, there would also be a risk that both Germany and the Netherlands would levy dividend withholding tax on distributions by Holdco, in addition to the risk of double taxation on the profits of Holdco itself.

Our ability to utilize our net operating loss and tax credit carryforwards to offset future taxable income may be subject to certain limitations, including losses as a result of the Business Combination.

We have incurred and are likely to continue incurring significant tax losses, which may be limited in their usability under German and other tax laws, in particular following significant shareholder changes. Although we do neither expect the Business Combination nor any of the ownership changes in the course of past financing rounds to result in a forfeiture of our German tax loss attributes, the realization of future tax savings from such tax loss attributes depends on the tax authorities’ acceptance of their continued availability and our ability to generate future taxable income in Germany against which such losses can be offset.

Risks Related to Holdco Being a Newly Incorporated Dutch Company

Holdco has no operating or financial history and its results of operations may differ significantly from the unaudited pro forma financial data included in this document.

Holdco has been recently incorporated and has no operating history and no revenues. Holdco’s unaudited pro forma condensed combined statement of operations included elsewhere in this proxy statement/prospectus combines Qell’s historical audited results of operations for the year ended December 31, 2020 with Lilium’s historical audited results of operations for the year ended December 31, 2020, and gives pro forma effect to the Business Combination as if it had been consummated as of January 1, 2020. Holdco’s unaudited pro forma condensed combined balance sheet combines the historical balance sheets of Qell and Lilium as of December 31, 2020 and gives pro forma effect to the Business Combination as if it had been consummated on such date.

The unaudited pro forma condensed combined financial statements are presented for illustrative purposes only, are based on certain assumptions, address a hypothetical situation and reflect limited historical financial data. Therefore, the unaudited pro forma condensed combined financial statements are not necessarily indicative of the results of operations and financial position that would have been achieved had the Business Combination been consummated on the dates indicated above, or Holdco’s future consolidated results of operations or financial position. Accordingly, Holdco’s business, assets, cash flows, results of operations and financial condition may differ significantly from those indicated by the unaudited pro forma condensed combined financial statements included in this proxy statement/prospectus.

The rights of shareholders in companies subject to Dutch corporate law differ in material respects from the rights of shareholders of corporations incorporated in the United States.

At Closing, we will be a public limited liability company incorporated under Dutch law. Our corporate affairs are governed by our articles of association, our internal rules and policies and by the laws governing companies incorporated in the Netherlands. The rights of shareholders may be different from the rights and obligations of shareholders in companies governed by the laws of U.S. jurisdictions. The role of the management board in a Dutch company is also materially different, and cannot be compared to, the role of

TABLE OF CONTENTS

a board of directors in a corporation incorporated in the United States. In the performance of their duties, our management board is required by Dutch law to consider the interests of our company and the sustainable success of its business, with an aim to creating long-term value, taking into account the interests of its shareholders, its employees and other stakeholders of the company, in all cases with due observation of the principles of reasonableness and fairness. It is possible that some of these parties will have interests that are different from, or in addition to, your interests as a shareholder.

We are not obligated to, and do not, comply with all best practice provisions of the Dutch Corporate Governance Code.

We will be subject to the Dutch Corporate Governance Code (the “DCGC”). The DCGC contains both principles and best practice provisions on corporate governance that regulate relations between the management board and the general meeting of shareholders and matters in respect of financial reporting, auditors, disclosure, compliance and enforcement standards. The DCGC is based on a “comply or explain” principle. Accordingly, companies are required to disclose in their annual reports (which are filed in the Netherlands) whether they comply with the provisions of the DCGC. If they do not comply with those provisions (for example, because of a conflicting Nasdaq requirement), the company is required to give the reasons for such noncompliance. The DCGC applies to Dutch companies listed on a government-recognized stock exchange, whether in the Netherlands or elsewhere, including Nasdaq.

We acknowledge the importance of good corporate governance. However, we do not comply with all the provisions of the DCGC, to a large extent because such provisions conflict with or are inconsistent with the corporate governance rules of Nasdaq and U.S. securities laws, or because we believe such provisions do not reflect customary practices of global companies listed on Nasdaq. Any such noncompliance may affect your rights as a shareholder, and you may not have the same level of protection as a shareholder in a Dutch company that fully complies with the DCGC.

Shareholders may not be able to exercise preemptive rights and, as a result, may experience substantial dilution upon future issuances of shares.

In the event of an issuance of our class A shares and our class B shares, subject to certain exceptions, each shareholder will have a preemptive that is right pro rata to the total amount of class A shares or class B shares (as applicable) held by such shareholder. These preemptive rights may be restricted or excluded by a resolution proposed by the management and adopted by the general meeting of shareholders. Prior to the Closing, our board will be authorized for a five-year period to issue shares or grant rights to subscribe for shares up to our authorized share capital and to limit or exclude preemptive rights in connection therewith, which could cause existing shareholders to experience substantial dilution of their holdings.

The dual class structure of Holdco has the effect of giving a greater percentage of voting rights than economic rights to Daniel Wiegand, Lilium’s founder and Chief Executive Officer.

Holdco Class B Shares will have three times as many votes per share, for a total of 36 votes per share on any matter submitted for shareholder approval, as opposed to the Holdco Class A Shares, which have 12 votes per share. As of the closing of the Business Combination, Daniel Wiegand, Lilium’s founder and Chief Executive Officer, will hold all of the issued and outstanding Holdco Class B Shares and will control between 20.5% and 22.9% of the total voting power in the company (depending on redemption levels and the assumptions set forth under “Beneficial Ownership of Holdco Securities”). Accordingly, Mr. Wiegand, like all shareholders with greater than 10% voting power in the company, will be able to call a special meeting of shareholders to propose matters for shareholder approval such as the removal or election of directors or amendments to the company’s organization documents. Mr. Wiegand may have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. For information about Holdco’s dual class structure, see the section titled “Description of Holdco Securities.”

Dividend Policy

Under Dutch law, we may only pay dividends to the extent our shareholders’ equity (eigen vermogen) exceeds the sum of the paid-up and called-up share capital plus the reserves required to be maintained by Dutch law or by our articles of association and (if it concerns a distribution of profits) after adoption of the annual accounts by our general meeting of shareholders from which it appears that such distribution is allowed. Subject to such restrictions, any future determination to pay dividends will be at the discretion of the board and will depend on a number of factors, including our results of operations, earnings, cash flow,

TABLE OF CONTENTS

financial condition, future prospects, contractual restrictions, capital investment requirements, restrictions imposed by applicable law and other factors considered relevant by the board.

Our board may decide that all or part of our remaining profits shall be added to our reserves. After such reservation, any remaining profit will be at the disposal of the general meeting of shareholders at the proposal of our management board, subject to the applicable restrictions of Dutch law. Our board is permitted, subject to certain requirements, to declare interim dividends without the approval of the general meeting of shareholders. Dividends and other distributions shall be made payable not later than the date determined by the corporate body that declares the (interim) dividend. Claims to dividends and other distributions not made within five years from the date that such dividends or distributions became payable will lapse and any such amounts will be considered to have been forfeited to us (verjaring).

Investors may have difficulty enforcing civil liabilities against us or the members of our management and our board.

Holdco is incorporated in the Netherlands, and we will conduct substantially all of our operations in Germany or Europe through our subsidiaries. A majority of our management and our directors are not United States residents and do not have significant assets in the United States, and the majority of our assets are located outside the United States. As a result, it may not be possible, or may be very difficult, to serve process on company representatives or the company in the United States, or to enforce judgments obtained in U.S. courts against company representatives or the company based on civil liability provisions of the securities laws of the United States. There is no treaty between the United States and the Netherlands for the mutual recognition and enforcement of judgments (other than arbitration awards) in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the U.S. federal securities laws, would not be enforceable in the Netherlands unless the underlying claim is re-litigated before a Dutch court of competent jurisdiction. U.S. investors will be unable to enforce any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws, against us, members of our management and our directors. In addition, there is doubt as to whether a Dutch court would impose civil liability on us or the members of our management or our directors in an original action predicated solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in the Netherlands against us or our management or directors.

Dutch, German and European insolvency laws are substantially different from U.S. insolvency laws and may offer our shareholders less protection than they would have under U.S. insolvency laws.

As a Dutch public limited liability company and as a company with its ‘centre of main interest’ in Germany, we are subject to Dutch and German insolvency laws in the event any insolvency proceedings are initiated against us including, among other things, Regulation (EU) 2015/848 of the European Parliament and of the Council of May 20, 2015 on insolvency proceedings. Should courts in another European country determine that the insolvency laws of that country apply to us in accordance with and subject to such EU regulations, the courts in that country could have jurisdiction over the insolvency proceedings initiated against us. Insolvency laws in Germany, the Netherlands or the relevant other European country, if any, may offer our shareholders less protection than they would have under U.S. insolvency laws and make it more difficult for our shareholders to recover the amount they could expect to recover in a liquidation under U.S. insolvency laws.

Shareholders may be subject to limitations on transfer of their shares.

Our shares are transferable on the transfer agent’s books. However, the transfer agent may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the transfer agent may refuse to deliver, transfer or register transfers of shares generally when our books or the transfer agent’s books are closed, or at any time if we or the transfer agent deems it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

Cautionary Note Regarding Forward-Looking Statements

This proxy statement/prospectus contains forward-looking statements. Forward-looking statements provide Holdco’s current expectations or forecasts of future events. Forward-looking statements include statements about Holdco’s expectations, beliefs, plans, objectives, intentions, assumptions and other statements that are not historical facts. Words or phrases such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “objective,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will” and “would,” or similar words or phrases, or the negatives of those words or phrases, may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward-looking. Examples of forward-looking statements in this proxy statement/prospectus include, but are not limited to, statements regarding Holdco’s disclosure concerning Lilium’s operations, cash flows, financial position and dividend policy.

Forward-looking statements appear in a number of places in this proxy statement/prospectus including, without limitation, in the sections titled “Lilium’s Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Qell’s Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Business of Qell and Certain Information About Qell” and “Business of Lilium and Certain Information About Lilium.” The risks and uncertainties include, but are not limited to:
