Basis of Preparation and Changes to the Group's Accounting Policies	2. Basis of Preparation and Changes to the Group’s Accounting Policies The Group’s interim condensed consolidated financial statements for the six month periods ended June 30, 2023 and 2022 are prepared in accordance with IAS 34 Interim Financial Reporting. The interim condensed consolidated financial statements have been prepared on a going concern basis, applying a historical cost convention, unless otherwise indicated. They are prepared and reported in thousands of Euro (“€ thousand”) except where otherwise stated. Due to rounding, numbers presented may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures. The interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements and should be read in conjunction with the Group’s audited annual consolidated financial statements as of December 31, 2022. Consolidated entities are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ equity interest ​ ​ ​ ​ ​ ​ owned in % ​ ​ ​ Country of ​ Date of ​ June 30, ​ June 30, Name ​ Incorporation ​ incorporation ​ 2022 ​ 2023 ​ Lilium N.V.

Management assessed the Group’s ability to continue as a going concern and evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Group’s ability to continue as a going concern using all information available about the future, focusing on the twelve-month period after the issuance date of the financial statements. Historically, the Group has funded its operations primarily through capital raises and loans from shareholders. Since its inception, the Group has incurred recurring losses and negative cash flows from operations (accumulated losses of €1,355.7 million as of June 30, 2023). The Group expects to continue generating operating losses and negative cash flow from operations for several years. At the reporting date, the Group has a shareholders’ deficit of €84,553 thousand, which is mainly driven by the operational losses carried forward by the Group and the fair value movement of the warrants as disclosed in note 17. The going concern basis is driven by the Group’s available liquidity and its ability to settle its liabilities and commitments. The warrants are settled upon exercise by warrant holders via issuance of Class A Shares against the applicable exercise price without negatively impacting the liquidity of the Group. Lilium’s financing plan shows substantial financing needs for several years. Based on its business plan, the Group depends on additional financing for development activities and operations which is currently not assured. The Group’s current forecast indicates that the Group does not have sufficient funds to fund its operations for several years. Additionally, the Group must reach several milestones, including completion of its research and development program, and obtaining regulatory approvals, which will have an increased importance as the Group progresses towards commercialization. Consequently, the Group’s ability to continue as a going concern is largely dependent on its ability to successfully progress with its business model and to secure additional funds in the near future through a combination of debt financings, equity offerings, partnerships and grant funding. The Group plans to secure additional capital in the next 12 months and beyond through, for example, equity offerings, grants, debt financing, or collection of pre-delivery payments (“PDPs”) in order to continue as a going concern. Between the reporting date and the date these financial statements were made available, the Group received additional gross funding of approximately US$192 million from the issuance of additional Class A shares and warrants to purchase Class A shares, as well as the triggering of the Additional Funding Amount disclosed in note 21. There is no certainty that the Group will be successful in obtaining sufficient funding through PDPs, grants, additional private or public offerings of debt and/or equity. If the Group is unsuccessful in raising sufficient capital, the Group’s management will be required to undertake, and is committed to undertaking, additional significant cost-cutting measures including significant headcount reductions that could require us to curtail or discontinue our operations. Such cost-cutting measures should help maintain the liquidity of the Group within the twelve-month period from the issuance date of these interim consolidated financial statements and provide additional time for raising sufficient funds through the start of series production. Based on its recurring losses from operations since inception, expectation of continuing operating losses in the future and the need to raise additional capital to finance its future operations, which is not assured yet, the Group has concluded that there is substantial doubt about its ability to continue as a going concern, and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Despite this substantial doubt, management is continuing to take actions to secure sufficient financing, and thus believes that the application of the going concern assumption for the preparation of these consolidated financial statements is appropriate. New standards, interpretations and amendments adopted by the Group The accounting policies adopted in the preparation of the interim condensed consolidated financial statements are consistent with those followed in the preparation of the Group’s audited annual consolidated financial statements for the year ended December 31, 2022, except for the adoption of new standards effective as of January Several amendments apply for the first time in 2023, but do not have an impact on the interim condensed consolidated financial statements of the Group.

Significant Accounting Judgments, Estimates and Assumptions
Significant Accounting Judgments, Estimates and Assumptions	3. The preparation of the Group’s interim condensed consolidated financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the interim condensed consolidated financial statements. In preparing these interim condensed consolidated financial statements, management exercises its best judgement based upon its experience and the circumstances prevailing at that time. The estimates and assumptions are based on available information and conditions at the end of the financial period presented and are reviewed on an ongoing basis. Actual results may differ from these estimates under different assumptions and conditions and may materially affect the financial results or the financial position reported in future periods. Assumptions and estimates relating to the Group’s ability to continue as a going concern are described in note 2. The Group operates its business as a single operating segment, which is also its reporting segment. An operating segment is defined as a component of an entity for which discrete financial information is available and whose results of operations are regularly reviewed by the chief operating decision maker. The Group’s chief operating decision maker is the Chief Executive Officer, who reviews results of operations to make decisions about allocating resources and assessing performance based on consolidated financial information.

COVID 19 Risks and Uncertainties
COVID 19 Risks and Uncertainties	4. The Board is actively monitoring the impact on the Group from the uncertainty regarding the consequences and lingering impact of the COVID-19 pandemic. The Group had implemented logistical and organizational changes to bolster the Group’s resilience to the COVID-19 pandemic. The extent that COVID-19 continues to impact our business, prospects and results of operations will depend on future developments, which are highly uncertain and cannot be predicted. However, based on the latest developments, the Group expects business operations to continue with minimal to no ongoing impact from the COVID-19 pandemic for the foreseeable future. The Board is also actively monitoring the impact on the Group from the war in Ukraine. The Group does not and does not intend to have any operations in Ukraine, Belarus or Russia, or engage with direct suppliers located in Ukraine, Belarus or Russia. There is currently no direct impact on the Group from the war in Ukraine and sanctions imposed on Russia and Belarus as the Group does not have any operations or direct suppliers located in these jurisdictions. The Group continues to closely monitor the impact on general economic factors from the war in Ukraine, including the impact of inflation, as such puts pressure on the Group’s costs for employees, raw materials and other parts provided by suppliers. Finally, the Board is also actively monitoring geopolitical conflicts and tension, including the imposition of and changes in foreign investment, economic sanctions and trade control regulations that could adversely impact our business. There is currently no material impact on the Group’s operations from applicable foreign investment, economic sanctions and trade control regulations. However, the imposition of and changes in such regulations in the future could adversely impact our business.

Total options that vested during the period were 355,912 options (June 30, 2022: 1,545,389 options). The weighted average share price for exercised options has been €1.09 (June 30, 2022: €3.77). As of June 30, 2023, 6,026,558 options (December 31, 2022: 7,043,620 options) are vested and are exercisable at the request of the employee with a WAEP of €0.00 (December 31, 2022: €0.00). General population - Restricted Stock Units The expense recognized for participant services received during the six month periods ended June 30, 2023 and 2022 is shown in the following table: ​ ​ ​ ​ ​ ​ In € thousand June 30, 2023 June 30, 2022 Expense arising from equity settled RSU 2,312 1,728 ​ Movements during the periods The following table illustrates the number and WAEP of, and movements in, such RSUs during the six month periods ended June 30, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 ​ ​ ​ ​ 2022 ​ ​ ​ ​ ​ Number ​ 2023 ​ Number ​ 2022 (in units) of RSUs WAEP of RSUs WAEP Outstanding at January 1 4,275,098 ​ € 0.12 162,800 € 0.12 Assigned during the period 1,790,364 ​ € 0.12 2,782,614 € 0.12 Exercised during the period ​ (1,017,273) ​ € 0.12 ​ — ​ ​ — Forfeited during the period (272,914) ​ € 0.12 (9,837) — Outstanding at June 30 4,775,275 ​ € 0.12 2,935,577 € 0.12 ​ 1,790 thousand (June 30, 2022: 2,782 thousand) RSUs were granted during the period. As RSUs are exercised on vesting, none of the RSUs were exercisable as of June 30, 2023 and 2022. The weighted average remaining contractual life of RSUs outstanding at the six month period ended June 30, 2023 is 1.4 years (June 30, 2022: 0.4 years). Measurement of fair values The RSU are equity settled and have an exercise price of €0.12 per share, the nominal value of the underlying Class A Shares. The exercise price is significantly lower than the share price at grant date. Accordingly, the intrinsic value of the RSU has been used, i.e. the share price at grant date less the exercise price. During the period ended June 30, 2023, the weighted average fair value of RSUs granted or reasonably expected to be granted is €0.92 (June 30, 2022: €2.32). Executives - Employee Stock Option Program (“ESOP”) special vesting Some executives have received ESOP grants comparable with the general ESOP program, but with individual conditions in respect to the vesting scheme and with different exercise prices. The expense recognized for participant services received during the six month periods ended June 30, 2023 and 2022 is shown in the following table: ​ ​ ​ ​ ​ ​ In € thousand June 30, 2023 June 30, 2022 Expense arising from equity-settled share-based payments 504 1,705 ​ Movements during the periods The following table illustrates the number and WAEP of, and movements in, such stock options during the six month periods ended June 30, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 ​ ​ ​ ​ 2022 ​ ​ ​ ​ ​ Number ​ 2023 ​ Number ​ 2022 (in units) of options WAEP of options WAEP Outstanding at January 1 728,020 ​ € 6.94 1,888,477 € 7.90 Granted during the period — ​ — — — Forfeited during the period (302,327) ​ € 8.47 (86,796) € 8.90 Outstanding at June 30 425,693 ​ € 5.85 1,801,681 € 7.85 ​ Total options in Lilium N.V. shares vested during the period ended June 30, 2023 was 79,795 options (June 30, 2022: 159,995 options). As of June 30, 2023, 308,917 (June 30, 2022: none) of the options granted under the ESOP plan are exercisable, with a WAEP of €0.00. The weighted average remaining contractual life is 10.9 years (June 30, 2022: 11.9 years). Measurement of fair values No options have been granted in the first six months of 2023 (June 30, 2022: Nil) under this plan, hence no valuation was necessary. Executives - Restricted Stock Units The expense recognized for participant services received during the six month periods ended June 30, 2023 and 2022 is shown in the following table: ​ ​ ​ ​ ​ ​ In € thousand June 30, 2023 June 30, 2022 Expense arising from equity settled RSU 1,845 1,676 ​ Movements during the periods The following table illustrates the number and WAEP of, and movements in, such RSUs during the six month periods ended June 30, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 ​ ​ ​ ​ 2022 ​ ​ ​ ​ ​ Number ​ 2023 ​ Number ​ 2022 (in units) of RSUs WAEP of RSUs WAEP Outstanding at January 1 2,324,725 ​ € 0.12 1,050,913 € 0.12 Assigned during the period 604,572 ​ € 0.12 370,434 € 0.12 Forfeited during the period (54,986) ​ € 0.12 (163,200) € 0.12 Exercised during the period (261,520) ​ € 0.12 (49,548) € 0.12 Outstanding at June 30 2,612,791 ​ € 0.12 1,208,599 € 0.12 ​ In the table above, assigned rights include granted rights as well as rights explicitly expected to be granted in the future. The weighted average remaining contractual life of such RSUs outstanding at June 30, 2023 is 0.9 years (June 30, 2022: 1.7 Measurement of fair values Similar to the RSUs for the general population, the exercise price is significantly below the share price at grant. While a Black-Scholes model was used to determine the RSUs fair market value, the outcome of the valuation basically reflects the intrinsic value of the RSU. Accordingly, input assumptions other than the share price are not material. For fair value calculations the share price was taken as the closing price at grant date of a Class A Share. The weighted average fair value of RSUs during the period was €0.99 (June 30, 2022: €2.95). Executives – Performance-based stock options The expense / (income) recognized for participant services received during the six month periods ended June 30, 2023 and 2022 is shown in the following table: ​ ​ ​ ​ ​ ​ In € thousand June 30, 2023 June 30, 2022 Expense/(income) arising from performance-based stock options 1,058 (919) ​ Movements during the periods The following table illustrates the number and WAEP of, and movements in, such performance-based stock options during the six month periods ended June 30, 2023 and 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2023 ​ ​ 2022 ​ ​ ​ ​ Number of ​ 2023 ​ Number of ​ 2022 (in units) options WAEP options WAEP Outstanding at January 1 ​ 3,596,721 ​ € 7.94 ​ 7,036,501 ​ € 8.15 Assigned during the period — ​ ​ — 1,272,059 € 9.42 Forfeited during the period — ​ ​ — (4,711,839) € 8.66 Outstanding at June 30 3,596,721 ​ € 7.94 3,596,721 € 7.93 ​ As of June 30, 2023, no performance-based stock options were exercisable (June 30, 2022: Nil). The weighted average remaining contractual life is 9.0 years (June 30, 2022: 9.5 years). Measurement of fair values No performance-based stocks options were granted for the period ended June 30, 2023 and therefore no valuation was necessary. The following table lists the inputs to the Black-Scholes model used for the fair market value calculation for performance-based stock options for the period ended June 30, 2022: ​ ​ ​ ​ ​ ​ June 30, 2022 Risk free rate range 0.60 % - 0.81 % Expected dividend yield — Expected exercise term 3.3 years Expected volatility 109.9 % - 111.4 % ​ The expected volatility was based on an evaluation of the historical volatilities of comparable listed peer group companies. It reflects the assumption that the historical volatility is indicative of future trends, which may not necessarily be the actual outcome. For fair value calculation the share price was taken as the closing price at grant date of a Class A Share. There were no new grants for the period ended June 30, 2023 (June 30, 2022: 1,006 thousand performance-based stock options were granted with the weighted average fair value of €1.12 and exercise prices within the range of €9.39 to €9.55).

The weighted average remaining contractual life is 9.0 years (June 30, 2023: 9.9 years). Measurement of fair values No time-based stocks options were granted for the period ended June 30, 2023 and therefore no valuation was necessary. The following table lists the inputs to the Black-Scholes model used for the fair market value calculation for time-based stock options granted for period ended June 30, 2022: ​ ​ ​ ​ ​ ​ June 30, 2022 Risk free rate (0.69%) – 0.21 % ​ Expected dividend yield 0 ​ Expected exercise term 9.9 years ​ Expected volatility 121.9 % - 124.1 % ​ ​ The expected volatility was based on an evaluation of the historical volatilities of comparable listed peer group companies.

Other common inputs to option pricing models such as discount rate, dividends expected and expected term. For fair value calculation the share price was taken as the closing price at grant date of a Class A Share. The weighted average fair value of time-based stock options granted during the period was €0.00 (June 30. 2023: €1.57). The weighted average exercise price of the option is €0.00 (June 30, 2023: €3.62). Executives - Joint Stock Ownership Plan (JSOP) and bonus Expenses/(income) during the six month periods ended June 30, 2023 and 2022 from the JSOP and the bonus are shown in the following table: ​ ​ ​ ​ ​ ​ In € thousand June 30, 2023 June 30, 2022 Income for JSOP — (2,718) Income for bonus — (693) Total income — (3,411) ​ In December 2022, the recipient exercised the option to settle the JSOP and the bonus.

The amounts are accounted for as an equity-settled share-based payment and €3,304 thousand (June 30, 2022: nil) have been recognized in other capital reserves. During the period €4,561 thousand (June 30, 2022: nil) has been recognized as a share-based payment expense for the services rendered by the vendor. In November 2022, the Group entered into a Share Issuance Agreement with the same vendor, with the option at the Group’s discretion to pay for the IT services to be rendered by the vendor either via the issuance of 3,101,523 units of Class A shares of Lilium N.V. or cash of US$4,500 thousand.

RDO Warrants & 2022 PIPE Warrants As of June 30, 2023, 11,249,997 (December 31, 2022: 11,249,997) RDO Warrants and 34,512,464 (December 31, 2022: 34,512,464) 2022 PIPE Warrants were outstanding. During the current period, the exercise price of the RDO & 2022 PIPE Warrants was reduced from US$1.30 per share to US$1.00 per share triggered by the issuance of the May 2023 Warrants and in line with the warrant agreement. May 2023 Warrants In May 2023, the Group executed a Securities Purchase Agreement (the “2023 SPA”) to issue to Aceville Pte. Limited (“Aceville”) in a private placement of 184,210,526 warrants (the “May 2023 Warrants”) to purchase one Class A Share for an exercise price of $1.00 per warrant. On the closing date, Aceville has partially prefunded the aggregate exercise price of the May 2023 Warrants in an amount of $100,000 thousand (the “Initial Funding Amount”) and also committed to prefund to the Group an additional $75,000 thousand (the “Additional Funding Amount”) of the aggregate exercise price, contingent upon the Group securing $75,000 thousand in additional funding from third parties. In July 2023, the Group satisfied the aforementioned condition and received the Additional Funding Amount as disclosed in note 21. Following the Group’s receipt of the Initial Funding Amount, the May 2023 Warrants were exercisable at the remaining unpaid exercise price of $0.4571 per Class A Share. Upon receipt of the Additional Funding Amount, the May 2023 Warrants are exercisable at the remaining unpaid exercise price of $0.05 per Class A Share. At initial recognition, the Group recorded a derivative financial asset of €82,829 thousand, recognized as a contribution from shareholder in other capital reserves, as described in note 20.

There were transfers between levels The fair values of the non-current security deposits are in level 2 and are determined as the principal balance discounted using market - based risk-free interest rate curves. The fair values of non-current trade and other payables measured at AC are determined as expected cash flows discounted using market-based credit risk adjusted interest rate curves that are applicable for the Group and specific for the residual term of each financial liability. These fair values would be classified in level 3 due to the Group's risk profile. The Public Warrants are traded in an active market and are therefore classified as level 1 of the fair value hierarchy. The Private Warrants have been classified as level 2 of the fair value hierarchy, however as the Private Warrants have the same characteristics as the Public Warrants, the same price has been used to determine their fair value. The Group engages external, independent, valuation specialists to determine the fair value of the Group’s RDO & 2022 PIPE Warrants, together with the May 2023 Warrants. The Group has internal processes in place to review the qualifications of the valuation specialists and the results from the valuation. The RDO & 2022 PIPE Warrants and the May 2023 Warrants were classified as level 3 of the fair value hierarchy, due to the inputs used to determine the fair value of these warrants. The fair value has been determined using a Monte Carlo simulation in a risk neutral framework. The primary inputs into the simulation included the following: closing price of a Class A Share as of June 30, 2023, expected stock price volatility for the expected term, term, risk-free rate and dividend yield. The May 2023 Warrants include an additional funding clause, which as at June 30, 2023 was considered likely to be triggered in the next two years based on management’s expectation. At initial recognition, the RDO & 2022 PIPE Warrants contain a strike price reduction clause that has not been explicitly modelled, since the indication of the triggering event was deemed remote at issuance and at the end of FY2022. As a result of the issuance of the May 2023 Warrants in May 2023, the anti-dilution clause of the RDO & 2022 PIPE Warrants was triggered and resulted in a reduction of the strike price of the RDO & 2022 PIPE Warrants from $1.30 to $1.00. Since the likelihood of future issuances of new warrants with a lower strike price is deemed to be very low, the clause was not explicitly modelled within the valuation model at the reporting date. The expected stock price volatility was based on Lilium N.V. implied volatilities of 79% (December 31, 2022: 70%) which was derived from the price of LILMW and applied to RDO & 2022 PIPE Warrants. The May 2023 Warrants’ volatility was adjusted to 69% to reflect a more established status of the Company and Class A Shares at the long-term expiry. The term input used is equal to the initial 4 years from date of issuance of the RDO & 2022 PIPE Warrants and 15 years from date of issuance of the May 2023 Warrants less the time passed since issuance. The risk-free discount rates are bootstrapped out of USD Secured Overnight Financing Rate (“SOFR”) par swap rates. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero. As of June 30, 2023, the Group has used a probability of receiving the Additional Funding Amount of 85% by the end of 2024 for the valuation of the May 2023 Warrants. If for each of the annual conditional probabilities of the Additional Funding Amount an absolute shift of +/- 10% was assumed, the impact to the fair value would have been (€6,795 thousand)/ €5,794 thousand.

The Group is required to issue, subject to the execution of definitive agreements, warrants to purchase up to 6,200,000 Class A shares to Azul as described in note 15, which, if issued, are expected to vest in three tranches upon achieving certain performance and market conditions. As of the date these condensed interim financial statements were approved, no definitive agreements with respect to the acquisition of Lilium Jets or any other collaboration have been executed with Azul. On April 18, 2022, a putative class action was filed against Lilium N.V., Daniel Wiegand, Geoffrey Richardson, and Barry Engle for purported violations of United States securities laws. This lawsuit was filed in the U.S. District Court for the Central District of California. On February 10, 2023, the U.S. District Court for the Central District of California transferred the action to the U.S. District Court for the Southern District of Florida. The lawsuit is presently captioned as: Maniraj Ashirwad Gnanaraj v. Lilium N.V. et al., 2:22-CV-80232-Rosenberg/Reinhart. On February 15, 2023, the court entered an order appointing Jonathan Coon as Lead Plaintiff. On March 10, 2023, Lead Plaintiff filed an amended complaint that adds additional defendants and asserts additional claims for purported violations of the United States securities laws. The Group’s management believes the claims are without merit and intend to vigorously defend this litigation. To that end, on May 12, 2023, Defendants moved to dismiss the amended complaint. On July 12, 2023, Lead Plaintiff Jonathan Coon filed a memorandum of law in opposition to Defendants’ motion to dismiss. Defendants’ reply memorandum of law was filed on August 11, 2023. Given that the lawsuit is currently at a preliminary stage and the Group cannot predict its outcome, the Group cannot determine the likelihood of loss or estimate a range of possible loss. The Group entered into a success fee arrangement in November 2022 with an entity controlled by a former member of key management personnel shortly after cessation of employment, in which the Company will pay a percentage of future fundraising up to a cap of €9,111 thousand ($9,900 thousand) for a period of 12-months from the date of signing. As of June 30, 2023, a commitment of €8,191 thousand ($8,900 thousand) remained on the contract.
