Financial highlights Eve Air Mobility is an aerospace company dedicated to the development of an eVTOL (electric Vertical Takeoff and Landing) aircraft and the Urban Air Mobility (UAM) ecosystem that includes the aircraft development, Service & Operations Solutions and an Urban Air Traffic Management (Urban ATM) system. Eve is pre-revenue; we do not expect meaningful revenues, if any, during the development phase of our aircraft, and we expect financial results to be mostly related to costs associated with the program’s development during this period. Fourth Quarter Eve reported a net loss of $39.3 million in 4Q23 versus $20.1 million in 4Q22. Adjusting for non-recurring selling, general and administrative (SG&A) charges of $2.6 million incurred in 4Q22 – mostly related to new warrants issued during the period, net loss then was $17.5 million. In 4Q23, Eve recognized a $1.1 million SG&A gain on the forfeiture of Restricted Stock Units (RSUs) with the resignation of a former CEO, so recurring net loss in 4Q23 was $40.4 million. The increase in recurring net losses in the quarter was mostly driven by higher Research & Development (R&D) expenses, which are costs and activities necessary to advance in the development of our suite of products and solutions for UAM, including the Master Service Agreement (MSA) with Embraer. R&D expenses were $33.6 million in 4Q23, versus $18.0 million in 4Q22. Our R&D costs are primarily driven by the MSA with Embraer that performs several developmental activities for Eve. These efforts continue to intensify as the development of the eVTOL progresses, including the purchase of parts, assembly of our first full-scale prototype, and continued engineering, program development and testing infrastructure. When excluding the non-recurring expenses mentioned above, SG&A remained relatively flat at $6.4 million in both 4Q22 to 4Q23, even though the number of direct employees at Eve continues to grow. Higher personnel compensation was offset by reductions in outsourced services and Directors & Officers insurance. Eve’s total cash consumption in 4Q23 was $24.5 million, versus $20.8 million in 4Q22. R&D associated with Eve’s aircraft development and SG&A expenses were the main contributors to the higher cash consumption during the quarter. Full Year Net loss in 2023 was $127.7 million, vs. $174.0 million the year before. R&D expenses reached $105.6 million in 2023, versus $51.9 million 2022, while recurring SG&A expenses increased from $19.9 million in 2022 to $24.2 million in 2023. Like the quarterly numbers, these higher accumulated costs and expenses are primarily driven by increased developmental activities necessary to progress the eVTOL design. Including personnel contracted through the MSA with Embraer and its subsidiaries, as of 4Q23 Eve employed approximately 700 full-time collaborators, versus approximately 420 at the end of 2022. In 2023, cash consumption was $94.7 million and $59.9 million in 2022 – this compares with a range of $130 to $150 million we had expected to consume in the program and other supporting activities throughout the year, thanks to our focus on cost control, the deferral of certain supplier contracts payments, and continued synergy gains with Embraer. At the end of 2023, Eve’s cash, cash equivalents, financial investments, and related party loan receivable totaled $241.1 million – compared to $310.6 million at the end 2022, and was down just $15.2 million in the quarter, reflecting the withdrawal of the second tranche of the two credit lines from Brazil’s National Development Bank (BNDES) that had been approved in December 2022. As of December 2023, Eve had drawn ~US$26.1 million (R$126.2 million) of the total available funds of ~US$100 million (R$490.0 million) from BNDES. We believe both lines offer attractive terms and conditions that are aligned with Eve’s early-stage development, with long-term maturity and amortization grace period, which we expect will support Eve as it continues to advance its eVTOL program. Eve’s 2023 total liquidity – including undrawn portions of the BNDES credit lines is $316.3 million. We expect to continue drawing from these facilities through the end of 2024, as we aim to optimize our cash position and capital structure and continue the development of our eVTOL program. eVTOL program.

We had previously received the necessary tooling and carbon laminates to be used in the manufacturing process of the composite wing. It is now nearly complete with harness – a complex system of wires and electrical cables that is used to connect electrical and electronic components to flight surfaces and sensors with necessary redundancies in the system for safety as well as internal structures. Next, we plan to install, still in March the control surfaces – ailerons and rudder, and the electric actuators to move them and direct the eVTOL mid-flight. Internally, the wing is made up of ribs – the “skeleton” that gives it a lightweight and robust structure and its aerodynamic shape, and spars – attachments to the fuselage. These are designed to be strong and flexible and support the weight of the aircraft safely considering the inherent in-flight stresses they will experience. Separately, we are assembling the empennage. It too is made up of composite materials – for a lightweight and reliable structure, with its own harness, spars and ribs. The empennage will house the dual in-line electric motor for the pusher – this will be used in the cruise phases of the flight and be powered by a carbon-fiber propeller in a five-blade configuration. All the aircraft propellers – for the pusher and eight rotors, were designed to maximize the thrust / energy requirement equation, while also reducing sound emission. We have thoroughly tested several different propeller configurations with varying shapes, angles of attack and areas in our CFD models as well as in custom-built motor-propeller rigs to achieve optimal efficiency of our current design. And, unlike the propeller in the pusher for horizontal flight, the rotor propellers will have two blades. To reduce aerodynamic drag during the cruise flight, they will face forward and rest perpendicular to the wing once the aircraft has enough lift in the wing for airplane-like flight. Lastly, we have positioned the wing and empennage on the fuselage– shown in the left. The picture also shows the future placement of the four pylons – in red marking on the ground, the structures that house the motors and connect them to the wing. Each pylon will have an electric propulsion system at the front and one at the rear. We plan on installing the composite “skin” of the eVTOL, later in the assembly process, and once all the internal work is complete. The aircraft will have similar dimensions to popular helicopters that also have a capacity for four passengers. With a wingspan of 50ft (15.2m), 11ft (3.3m) cabin length, it was designed to fit in most of the currently available helipads.

eVTOL factory Earlier in the year, we selected a former Embraer site in the city of Taubaté, São Paulo - Brazil, to house our first production site, with total capacity of 480 units / year. We intend to start preparing the facility to accommodate our initial production efforts in 2024. This will require specialized tooling and equipment, some civil construction and upgrade of facilities for aircraft and equipment tests. We will implement a modular manufacturing approach – with four equally-sized modules to maximize the efficiency of our capital deployed in the site. • Total cash consumption With intensifying program development efforts, continued supplier selection, assembly of our prototypes, and necessary investments in the production site, Eve expects a total cash consumption between $130 and $170 million in 2024. This compares to $59.9 million invested in the program in 2022 and $94.7 million in 2023. The additional program activities will require an increase in the number of engineering hours – via our MSA with Embraer as well as direct Eve personnel, and the acquisition of raw materials and parts/components for our prototypes. Additionally, we will increase engagement with selected suppliers and receive equipment during the remainder of 2024, which will trigger additional cash consumption in the coming months. While we continue to expect sequentially higher investments and expenses in the quarters ahead due to intensifying engineering engagement as well as potential supplier payments, we are confident that our current liquidity is sufficient to fund our operations, design and certification efforts through 2025.

These new suppliers are in addition to Garmin, Liebherr Aerospace and Intergalactic that were announced in October and Nidec Aerospace LLC, a joint venture between Japan’s Nidec Corporation and Brazil’s Embraer, BAE Systems and DUC Hélices Propellers which were announced at the Paris Air Show last summer. Urban Air Traffic Management (UATM) U.K. Simulation Eve’s Urban ATM software is an agnostic solution that will enable the integration of all airspace users in the urban environment. We believe this to be critical to support the safety, efficiency, and improvement of the entire UAM ecosystem, including fleet and vertiport operators and help it scale globally. Eve has engaged Atech, Embraer’s Air Traffic Control technology and system integrator company, to support the development of the Urban ATM software solution. Eve is leveraging Atech’s experience in developing aviation-grade products for ATM systems in Brazil. From before take-off to after landing, the urban air environment will count on integrated systems, services and technologies being developed by Eve to support eVTOL operations alongside UATM systems and many other airspace users. In the future, the advancement of infrastructure and regulation will rely on these network management services to enable autonomous flight. The company continues to collaborate with regulators, customers air navigation service providers, fleet operators, vertiport developers, airports and other UAM ecosystems stakeholders globally to advance concepts and develop technology to support initial operation and scaling of UAM operations from an ATM perspective. One example of such collaboration is a successful 5-day simulation conducted in the United Kingdom with Flexjet. This test was used to validate and refine our software under real-world conditions. Our software was used in parallel to the incumbent software to simulate the functions. While not actively carrying out the functions and operations itself, the software was tested through the actual business operations, as opposed to simply prescribing a specific scenario. This tested and demonstrated the robustness of the software we have developed within the context of a real-world environment to better understand the commercial viability and applications of the product. Our solution was deployed to track 18 separate flights flown by different aircraft across a dynamic network of 8 aerodromes. The simulation included a playbook of 26 different routes, with alternative landing locations to test standby flight plan functionality. Besides running simulations under normal conditions, our team also tested delay at departure, delay at destination – with impacts in incoming flights, delay and/or flight cancellation due to airspace/weather constraints, in-flight emergency and alternative landing location. More details on page 11 of this report. Backlog, Order Pipeline Services & Operations Solutions Eve is replicating elements of Embraer’s proven business model, namely the design, manufacturing, and sale of aircraft. In addition, we will also provide MRO (Maintenance, Repair and Overhaul) services on an agnostic basis worldwide. With that, Eve is uniquely positioned to serve its customers by leveraging Embraer’s global presence with local support and has secured non-binding contracts for Services & Operations Solutions across the world with 10 customers. Combined, these customers have placed LOIs for approximately 1,000 of our eVTOLs. These contracts include MRO, training, battery services, data integration and spare parts solutions, as well as component repair. These functions will be enhanced by a MoU (Memorandum of Understanding) signed with DHL Supply Chain to optimize supply chain to service centers. The MoU will also focus on batteries and the specific requirements for transporting, storing, and disposing of those devices. These non-binding Service & Operations Solutions contracts are estimated to bring potential revenues of $660 million during the first five years of the vehicle operation and because of our agnostic approach to the maintenance business, Service & Operations Support revenues could precede the first delivery of our eVTOL.

Latest Highlights Eve and Kookiejar to develop UATM system for operations in Dubai On November 13, Eve and Kookiejar, a Swedish-based vertiport developer, signed a letter of intent (LOI) for Eve’s Urban ATM (Air Traffic Management) system to support vertiport operations in Dubai. The agreement marks Eve’s first Urban ATM agreement in Dubai and Kookiejar becomes the company’s 10th Urban ATM customer and fifth vertiport customer as the company continues to grow its global customer base.

Eve collaborates with Flexjet to advance UAM through innovative software simulation On November 30, Eve achieved a key milestone in the progression of Urban Air Mobility (UAM) through a collaborative partnership with global private aviation leader Flexjet. Together, the companies have conducted an initial software simulation of Eve’s cutting-edge Urban Air Traffic Management (Urban ATM) solution. The initiative validated and refined the software through user testing and feedback on its interface and industry value. With London being one of the world’s foremost helicopter markets and a key focus for future eVTOL operations, the simulation took place over four days at Flexjet’s Tactical Control Centre at Farnborough Airport, UK, and saw Eve’s Urban ATM software shadowing live helicopter flights operated by Flexjet’s UK helicopter division, performing the kind of services that will be essential to enabling future UAM operations. Flexjet operates a fleet of 11 helicopters in the UK and its group of companies is one of Eve’s Urban ATM Fleet Operator customers. Leading UK helicopter operator Flexjet provided its helicopter fleet to perform flights, collaborating closely with Eve’s Urban ATM team. NATS, the UK’s leading provider of air traffic control services, and London Heliport supported the initiative by providing additional feedback to help ensure Eve’s solution will provide the greatest value to all UAM ecosystem participants. The initiative encompassed various aspects of operations, including regular business operations, atypical scenarios and flights tailored to an eVTOL aircraft’s specific needs, enabling the demonstration of product behavior in various real-world scenarios. The integration of vertiports to efficiently manage resources was the primary focus of the test, in addition to verifying and validating a subset of the Urban ATM product capabilities, with a specific emphasis on the UAM fleet operator support tool. Eve’s objective with this collaboration was to provide insights into the services required to support future eVTOL operations safely and efficiently. Another aim was to investigate whether these new services may have immediate value for existing helicopter operations. Following the simulation, Eve and Flexjet reviewed the findings and discussed recommendations for improvements, changes, and potential integration requirements. The companies will also continue to explore opportunities for further integration of existing software tools, enhancing the potential of the Urban ATM solution.

Electric UAM has the capability to improve the affordability of urban flights for communities, compared to current helicopter operations, and features a streamlined and efficient design, which contributes to reduced operational and maintenance costs. Eve’s Urban ATM solutions will support this by maximizing the utilization of aircraft and vertiports, further reducing operational costs. This innovative collaboration between Eve and Flexjet is a testament to their commitment to shaping the future of urban air mobility and providing efficient and sustainable solutions for the future of urban transportation.
