Exhibit 99.1







Dear Lilium shareholders,


An important phase has begun at Lilium, with the start of our eVTOL Jet’s industrialization phase. My joining Lilium as CEO couldn’t have come at a better time.


I am an executive with 30 years’ experience in aerospace, most recently as Head of the A320 family Program and Head of Services at Airbus. In these roles, I led the development, certification, production ramp-up, and operational deployment of the most successful large commercial aircraft in history.


Along the way, I got to know first-hand the importance of safety, customer-focus and unit economics. I have also experienced the “manufacturing hell” of ramping up the production of large complex aircraft.


So why am I so excited to join Lilium and how will I contribute to the mission?


It all starts with the aircraft itself, its unique architecture, and the electric jet propulsion technology behind it. Quite simply, I’m convinced that the Lilium Jet will be the best aircraft in its class. I also believe this unique eVTOL architecture has been rigorously conceived and validated. Its ducted-jet technology makes it suitable for multiple use cases including premium customers, commercial shuttles, cargo and other applications we have yet to develop. It is both versatile and scalable to larger form-factors, and I strongly believe it will form the basis for a complete product family. It also features multiple ground-breaking new technologies that may spin off into other sectors.


Furthermore, decarbonization is one of the great challenges of our times and the aerospace industry needs to face that head on. I am convinced that the Lilium Jet is one critical step in aviation’s shift to a sustainable and exciting future. The experience we are building today in electric propulsion, flight mechanics and aerospace-grade batteries will contribute to transforming the world of aviation.


I am very much looking forward to steering the company through this next decisive phase. I also wish to thank our co-founder and former CEO Daniel Wiegand for being a great partner to me over the last couple of months. I am excited that he’s back to what he loves best, leading Lilium’s future technology as Chief Engineer for Innovation & Future Programs. While working with Daniel to chart this future, let me assure you that I will remain laser-focused on operational excellence, engineering execution and cost discipline as we move ahead mile-stone by milestone towards our commercial launch.

Business Update │Q2 20222


Key highlights


The Lilium Jet program is now moving into the certification and industrialization phase. Over the past few months, we achieved the following milestones:



1High-speed full transition flight


Wing-borne flight on main and canard wings at ~100 kt (~190 km/h) achieved on our Phoenix 2 technology demonstrator aircraft which aligns precisely with computer model predictions, supporting certification


2Battery aging performance


Internal cycle tests have indicated that we can achieve the targeted 800+ cycles for launch; additional testing through independent laboratories underway


3Aircraft industrialization


On track to start assembly of Type-conforming aircraft in 2023. Additional partnerships signed with Tier 1 aerospace suppliers Diehl, Expliseat, Astronics, MA Group, L3Harris


4Expanded sales portfolio


Agreements for 483 aircraft moving toward detailed terms and firm contracts with pre-delivery payments in 2023


5Significant inbound interest in premium private sales


Decision to launch limited edition including receipt of deposits




Business Update │Q2 20223





Full Transition Flight & Flight Physics Validation


Our technology demonstrator, Phoenix 2, has recently achieved another industry first for an electric jet aircraft, performing at ~100 kt full transition from hover to wing-borne flight on both the main and canard wings at our test facility in Atlas, Spain.


Transition represents the technically challenging phase (for eVTOL aircraft) between powered vertical lift and the highly efficient wing-borne lift.


The fact that the canard and the wing transitioned smoothly is an historic technical achievement in itself but perhaps more important is that the transition happened precisely where the flight physics computer models predicted it would.


From the beginning of Lilium, we developed our aircraft using sophisticated computer models to predict the behavior of the aircraft through each critical phase and under various failure scenarios. These models allowed us to develop and evaluate this unique architecture much faster and with greater confidence than traditional techniques would have permitted.


At each juncture, our computer models predicted what the real world aircraft would do - something now validated again by real world testing. And validated models are a key cornerstone to any certification program.


Phoenix 2 has been successfully performing test flights at the ATLAS center in Spain since Spring 2022, with the first ever main wing transition flight for an electric jet aircraft achieved in June. In July this year, media representatives from CNBC, Die Welt and others were able to witness first-hand Phoenix 2’s flights in Spain. The feedback we received was that all were impressed by the stable flights and the very low noise signature of the demonstrator aircraft.


The flight test campaign will be complemented soon by an additional demonstrator aircraft, Phoenix 3, which will allow us to increase the pace of testing and learnings.

Battery performance update


Test results on our prototype battery cells give us confidence that the batteries we plan to use inside our production aircraft at launch will deliver not only the required energy and power densities, but also the required aging performance.


As mentioned in our previous update from Q1 2022, our internal testing indicates that our chosen battery cell technology will meet the performance requirements of our launch aircraft. Current internal testing focused specifically on cell technology aging have indicated an anticipated cycle life of 800+ cycles with 80% capacity retention.


We will be moving forward with validation of these results with independent laboratories in the future. Our business projections for entry into service are based on a battery cell lifetime of 800 cycles.


Moreover, we continue to work with our technology providers to further improve cell performance and aging prior to launch.

Certification progress


EASA at forefront of eVTOL regulatory initiatives


Lilium’s primary airworthiness authority, EASA, continues to actively support the safe deployment of innovative electric air mobility services. In June of this year, EASA published a series of proposed rules for the operation of eVTOL aircraft in cities, the first comprehensive such regulations to be issued worldwide. Lilium has been actively supporting EASA as part of relevant working groups since 2019.


Progress towards next Type Certification milestone


Lilium is currently working closely with EASA towards the next major milestone on the Lilium Jet’s projected path to certification: agreement of the Certification Program including Means of Compliance (equivalent of the FAA G-2). Moving forward, we plan to provide a detailed overview charting the Lilium Jet’s progress towards certification with both EASA and the FAA (see below) so that shareholders, customers and suppliers have a clear view on our progress.



Final DOA audit targeted for H1 2023


In parallel with the Type Certification program, Lilium is working towards Design Organization Approval (DOA) with EASA. DOA is a necessary prerequisite for any aerospace company to obtain a Type Certification of its aircraft. Lilium is now advancing towards the third DOA audit, which is scheduled for the end of 2022. The fourth and final DOA audit is targeted for the first half of 2023. Upon completion of the final EASA DOA audit and any remaining open actions, Lilium expects EASA to grant a DOA. This is a significant milestone, demonstrating that Lilium has the capability to develop and certify commercial aircraft.


Business Update │Q2 20226




Industrial partnerships


Our goal is to start the assembly of our first Type-conforming aircraft in 2023 and achieve first manned flight of a conforming aircraft in 2024. On our path to these milestones, we have begun placing orders for subsystems and parts from leading aerospace suppliers.


Lilium previously announced partnership agreements with Honeywell (avionics), Honeywell/DENSO (e-motors), Aciturri (aerostructures), Aernnova (wing flaps), CustomCells (battery cells) and Livent (lithium applications in battery cells). In recent months additional key partners have joined our aircraft program, including Diehl for the interior, Expliseat for seats, Astronics for the energy management system, MA Group for the landing gear and L3Harris for the voice recorder.


These supplier partnerships are fundamental to establishing a dependable path towards certification and industrialization of the key subsystems of the aircraft, all of which need to meet rigorous aerospace quality standards.

Financial update


As our aircraft development program ramps up, we are maintaining our strict budgetary control. The total cash spend of €63 million in Q2 2022 was in line with the previous quarter (Q1 2022: €60 million).


Looking ahead, we are closely monitoring the effects of the conflict in Europe, inflation, financial markets and general economic factors on our business and planning. The advance of our development program through the detailed design and industrialization phase is expected to lead to increased supplier contracting activity from Q2 2022. We are working to offset the slight rise in related cash spending through active budgetary measures including headcount control. We expect full year 2022 total cash spend to be no more than ~ €250 million.


Our liquidity as of June 30, 2022 stood at €229 million.2 Additionally, the $75 million “equity line of credit” (ELOC) facility, established with Tumin Stone Capital, became effective on June 24, 2022.


Going forward, we have chosen to use euros as the reporting currency for our quarterly Shareholder Letters and Business Updates.3 Our IFRS financial statements are reported in euros and the vast majority of our liabilities and costs are euro-denominated.

Business Update │Q2 20229




Commercial progress


Since our last letter, Lilium has made significant progress in delivering its premium-first commercial plan:


1Additional Memorandum of Understanding (MoU) agreements in the premium segment, for a total of 113 aircraft in key locations with high demand
2This brings the overall number of Lilium Jet aircraft under MoU to 483
3We are launching in 2022 a campaign for private sales
4Lilium plans to begin signing firm orders from commercial operators, with the target of locking in meaningful deposits in 2023


A phased approach, starting with Premium


As outlined in our previous shareholder letter, for aircraft sales and launch operations expected in 2025, we are addressing in a first phase the premium general and business aviation markets, including charter operators, fractional ownership and private individuals.


In a second phase, we plan to roll out our six-passenger shuttle configuration to address demand for short regional scheduled services. We continue to be excited by Florida as well as several European regions (Southern France, Spain, Scandinavia, Benelux, Germany, etc.) for both the premium segment as well as scheduled shuttle routes.


Business Update │Q2 202210



Firm aircraft orders and pre-delivery payments


Lilium is also announcing the start of its sales campaign for private individuals to purchase a limited edition of the Lilium Jet, in response to strong customer interest. Customized to respond to the high demand for the Lilium Jet among individuals seeking the ultimate electric aviation experience, Lilium intends to offer a tailored cabin and dedicated services on attractive financial terms. The limited edition will be unveiled later this year, when we will begin taking orders and deposits.


Lilium also plans to sign firm aircraft orders with commercial operators starting next year and take meaningful deposits from those same customers by the end of 2023.


The right partners in the right locations


Following earlier MoU agreements with Azul (Brazil) and NetJets (US), Lilium continues to build meaningful commercial momentum. Through sales in Brazil, Florida, Southern France, Southern Spain, along with Norway, Benelux, Germany and Northern Italy, Lilium is targeting prime locations with (i) high proven demand for premi-um air mobility, and (ii) where we’ve identified strong commercial partners who wish to innovate and for whom sustainability is a stated priority.


The Lilium Jet is proving to be highly desirable in these markets, thanks to its ducted-jet architecture and the exacting safety standards of EASA, which requires a 10-9 safety level (less than one catastrophic failure in a billion flight hours), the same as for large commercial aircraft like the A320 and 100 times higher than for helicopters (10-7).



The most recent MoU agreements reaffirm the aircraft’s appeal in these target geographies: US-based operator, Bristow Group Inc, the leader in global VTOL solutions with a fleet of over 220 helicopters, selected the Lilium Jet to develop its eVTOL business line. Bristow also intends to cooperate on maintenance for the Lilium Florida network.


In addition, Lilium signed agreements with Helity Copter Airlines in Southern Spain, the ASL Group in the Benelux and AAP in Scandinavia. In September, GlobeAir, an innovative business jet operator based in Austria, signed an MoU with Lilium with the intention to purchase 12 aircraft to operate in Northern Italy and the French Riviera.


France, Northern Italy, Southern Spain, Scandinavia and the Benelux are key markets with high demand for sustainable premium on-demand air mobility. The innovative nature of our partners along with the selected locations are key to Lilium’s commercial success.
