May 12, 2025 Eve Air Mobility First Quarter 2025 Result eveairmobility.com

Milestones checklist Eve continues to advance its eVTOL development and testing phase and progress toward key program milestones. The main achievements are the quick progress in our program development and successful tests of our pusher motor after installation. Until now, Eve has focused on advancing our eVTOL development program concluding with the assembly of our full-scale prototype which will be used to validate our aircraft’s performance and flight envelope characteristics in a flight-test campaign that is expected to start this year. With funding secured through 2026, Eve will continue to accelerate program development with ambitious targets for 2025 and 2026: • Full-Scale Prototype First Flight and Start of Flight Tests Following the conclusion of the assembly of our first full-scale prototype, Eve is now running an extensive battery of ground tests on different aircraft components. These include the pusher motors which were recently powered on to validate thrust, vibration, energy consumption, sound emission, and other metrics, and tests on the dedicated communication link between the Remote Pilot Station (RPS) and the aircraft. Separately, we are performing tests on the lifter motors – on dynamometers and concluding the integration amongst the many systems of the prototype. Our engineers have run high and low-voltage systems tests, ventilation systems, and validated avionics and flight control integration, not to mention additional wind-tunnel tests to further validate the aerodynamic profile and loads of our eVTOL design and electromagnetic interference tests. These are later fed into our computer model to improve the fly-by-wire and simulator for pilot training. While we plan to initiate the test flights on our full-scale prototype in 2025, this campaign will not count towards our certification. The current prototype will validate multiple stages of our eVTOL’s flight envelope, including the transition between the vertical and horizontal phases of flight. Besides that, the prototype will also corroborate the performance characteristics of the many tests performed thus far – either by utilizing individual rigs, Computational Fluid Dynamics model to estimate lift, aerodynamic drag, sound emission, energy consumption, etc., or in different rigs or wind tunnels. The plan is to begin the testing phase with hover flights and gradually increase height and power. We plan to perform a partial transition (i.e., pusher engaged for horizontal flights, with lifters still engaged to maintain full vertical control). Finally, the flight tests will evolve to a complete transition, where only the pusher motors will be powered. At this stage, the lifters will be turned off, and lift will be provided entirely by the airflow around the wings, as in a typical airplane. This will complete the entire cycle of our eVTOL’s expected missions. Full-scale prototype performing ground test at Embraer’s GPX facility

Alignment of Detailed Certification Plan with ANAC and FAA On November 1, 2024, Brazil’s Civil Aviation Authority (ANAC) published the Basis of Certification for Eve’s eVTOL. This is a significant milestone for the eVTOL industry and will allow Eve to progress towards ANAC Type Certification (TC) and seek validation with the Federal Aviation Administration FAA. ANAC’s Basis of Certification establishes the first set of airworthiness criteria for eVTOLs in Brazil and follows Eve’s application for TC in 2022. It is a standard process for developing a new certification basis and an essential milestone in the project. Following the definition of the airworthiness criteria, Eve will focus on defining with ANAC the Means of Compliance, which we expect to be published by year-end. These are specific tests, analyses, and simulations that need to be successfully performed for TC to be granted. These tests are performed to prove the aircraft design, and that construction meets the safety standards laid out in the Basis of Certification. On October 22, 2024, the FAA issued the Special Federal Aviation Regulation (SFAR) that details the final rules for Advanced Air Mobility (AAM) and covers eVTOL. In general, the new FAA SFAR has been well received by the US Urban Air Mobility market, as it simplifies the pilot training process and allows single-pilot control eVTOLs, among other advances. When TC is granted, Eve plans to seek validation by other certification authorities worldwide. The company formalized the validation with the FAA in 2023, which enables Eve to actively work with the FAA during the certification process with ANAC, pursuing the concurrent issuance of each authority’s TC. • Initial Production of Certification Prototype In addition to the full-scale engineering prototype rolled out in July 2024, Eve plans to deploy five prototypes for the certification campaign, with an option for a sixth test aircraft if needed. While each prototype will have a specific intended goal and distinct role in the campaign; they all serve a common goal – to prove the safety and reliability of Eve’s eVTOL design for commercial operations. We are engaged with our suppliers, some of whom have started to produce parts for the first certification-compliant aircraft. Importantly, these aircraft will be piloted and have the systems/sub-systems and redundancies present in the commercial version of the aircraft. For instance, the aircraft will be fitted with passenger and pilot seats – not present in our remote-controlled prototype, and the batteries will be placed between the passenger seats and cargo area. This configuration will ensure that the certification-compliant prototypes have the exact dimensions and physical characteristics – including the commercial aircraft’s weight and center of gravity to provide high fidelity in the certification campaign vis-à-vis the expected performance of the commercial aircraft at entry into service. These will be extensively tested and used to accumulate hours towards certification. Importantly, Eve plans to initiate the certification campaign even before ANAC defines and publishes the Means of Compliance. Some components and systems can be tested on the ground and do not require tests to be performed during flight. These include, among others, select electrical systems – such as circuit breakers and systems integration. This should allow for a faster certification process at a lower cost.

• Preparation of eVTOL Manufacturing and Testing Facilities Earlier in 2023, we selected a former Embraer site in the city of Taubaté, São Paulo – Brazil, to house our first production site. The plan is to invest in a total capacity of 480 units/year on a modular basis to maximize the efficiency of our capital deployed, and we intend to start preparing the facility to accommodate our initial production efforts throughout the remainder of 2025. This requires specialized tooling and equipment, as well as some civil construction, and customization of facilities to accommodate aircraft and equipment tests. For instance, we will build helipads to test the aircraft after assembly and calibrate the avionics, given that the site does not currently have any such infrastructure. Electronics Calibration must be conducted at least 100 meters (~300 ft.) away from metal surfaces and electrical structures, such as light poles, electrical wires, plumbing, and other building infrastructure, to avoid interference from external electromagnetic sources. We will have to landfill the northern part of the site to house the helipads needed for this function and subsequent flight tests of commercial aircraft before delivery. With funding secured for the industrialization project – we have already secured new BNDES credit lines for the necessary investments; we are preparing the Taubaté site this year to produce our commercial aircraft. We estimate the customizations will require between $80 million / $90 million, and by leveraging one of Embraer’s sites in Brazil – rather than having to invest in a greenfield project, we believe we will manage to execute our industrialization strategy quicker and with fewer resources. In parallel, we selected an Embraer site in its main facility in São José dos Campos specifically to assemble the certification-conforming prototypes. We are getting ready to begin their assembly in the second half of 2025. We have prepared the site and are now waiting for the required tooling and equipment. • Total Cash Consumption Between $200 and $250 Million With intensifying program development efforts, continued supplier selection, assembly of our prototypes, and necessary investments in the production site, Eve expects total cash consumption between $200 million and $250 million in 2025. This compares to $141.2 million consumed in the program in 2024 and $94.7 million in 2023. With $25.3 million consumed in 1Q25, even with temporary working capital savings, cash use is well within our expected cash-consumption goals for the full year. The additional program activities will require an increase in engineering hours – via our Master Service Agreement with Embraer, and the acquisition of raw materials, components, parts, and tooling for our certification-conforming prototypes. Eve is also deploying capital to prepare the site for the conforming vehicles. Additionally, the level of engagement with our selected suppliers will continue to intensify – we will receive equipment during the year, which will trigger additional cash consumption in the coming months. Lastly, cash consumption in 2025 will also reflect the initial stages of necessary investments to prepare the Taubaté Facility for our needs. While we continue to expect sequentially higher investments and expenses in the quarters ahead – due to intensifying engineering engagement and potential supplier payments, we are confident that our current liquidity is sufficient to fund our operations, design, and certification efforts through 2026. Program Development Following the roll-out of our full-scale prototype in July 2024, our engineering team continues to advance developing our eVTOL. Since then, we have installed the batteries and initiated a series of tests to ensure that all the systems are properly integrated for a seamless flight campaign. These include – among others, Flight Test Instrument integration to validate proper system conformity as well as the dedicated radio link between the RPS and the prototype for proper communication and vehicular control during flight.

We have also calibrated the equipment necessary for navigation (Inertial System, GPS, and Radio Altimeter) to accurately measure the aircraft position and performance – altitude and speed. This is only possible after all cables and electric and electronic equipment are adequately insulated to prevent interference from external electromagnetic sources, such as power lines, and lightning, as well as transmitters like radio, television, or mobile phones. The High-Intensity Radiated Field tests conducted during the quarter provide direct feedback on the cabling properties of the aircraft and guarantee that the aircraft's systems can withstand these high-intensity fields without malfunction or failure. As published previously, our engineering team successfully installed and tested the pusher motors on the aft section of the aircraft (click here to watch the video). Although the motors were tested before installation – and confirmed expected thrust, energy consumption, vibration, and noise emissions, the onboard tests also validated that all connections and inverters were installed correctly. Onboard metrics also met engineering expectations. This is an essential milestone as Eve prepares to fly its full-scale prototype for the first time. We are going through the same testing protocol with the lifter motors individually – these are tested in dynamometers before installation on the prototype and commencement of the flight campaign. The tests will confirm that each motor produces the necessary thrust for the take-off and landing procedures of the flight schedule. The rigs are used to corroborate the energy requirement and expected drain on the entire system and that the inverters successfully manage the flow of energy during peak demand of the take-off and landing phases of the flight. Importantly, ANAC supervises these tests. The objective is to involve our primary certification agency early in the process to anticipate all potential findings during the official CAVE (Experimental Flight Permit Certificate) and improve the readiness before the first flight. Eve inherited many of Embraer’s development processes including specialized rigs to thoroughly test individual components before including the optimal configuration into the final architecture, as opposed to assembling a full aircraft from the outset. This approach expedites design, testing, and certification processes and reduces overall developmental costs. One such example is our Iron Bird. This is a structure built specifically to include the different components of the aircraft’s actual hardware (motors, battery, inverters, actuators, avionics, electrical and hydraulic systems, etc.) in the testing phase in a skeleton of an eVTOL. These different rigs are all connected and controlled by a pilot in a flight simulator. The entire system reacts physically to pilot inputs read by the flight control system or joystick. The motors (lifters and pushers) spin at the appropriate revolutions per minute to produce the necessary power for the intended maneuver. The actuators are engaged to control the flight surfaces and direct the aircraft in the desired direction. Avionics measures the flight's performance and metrics. All the while, the battery powers the entire system, and the fly-by-wire controls the pilot's commands vis-à-vis the safe performance envelope of the eVTOL. Importantly, although the Iron Bird is a “de-constructed” eVTOL, it is built with the exact specifications of the final aircraft – the electric and electronic cable and wires have the same length, width, and insulation, the motors are the same, as are other components. It utilizes the same battery as the final aircraft – with the same thermal management system. This applies to inverters, actuators, and all other flight-critical systems. Anecdotally, the landing gear of Embraer’s E-2 Iron Bird gets retracted/deployed at every simulated take-off and landing cycle. It also mimics the aircraft pressure on the gear as it touches the ground – with a hydraulic system, yielding valuable information on the behavior and durability of all components. The Iron Bird is an important tool for assessing the systems’ actual physical performance and how well the many components and sub-systems work together. It also yields benefits for our TechCare suite of aftermarket services, because it can predict the wear and tear of different components and the structural integrity of the airframe, thus enabling preventive maintenance.

Full-scale prototype performing first pusher motor run Backlog, Order Pipeline eVTOL Orders Eve’s order pipeline totals roughly 2.8K units, with a total non-binding backlog value of approximately $14 billion. This value is based on a list price methodology that is common in the aviation industry and incorporates internal and external factors to define a standard price. Eve will not disclose specific deal prices and will use the list price as a reference for future transaction values. Our initial order pipeline is based on non-binding Letters of Intent (LOI) and is, therefore, subject to change, consistent with customary aviation practices. Eve’s current client base consists of 28 customers, with no client representing more than 14% of the total order book, including options. The order book is further diversified by the industries in which these customers operate, with fixed-wing operators representing 40%, helicopter operators 27%, lessors 17%, and ride-sharing platforms 11%. Lastly, Eve has received LOIs from clients in nine different countries spread over five continents around the globe. The Americas is home to close to two-thirds of Eve’s backlog (North America is 47% and South America 18%), while Europe represents 16% of the LOIs, and Asia 9%. TechCare Eve is replicating elements of Embraer’s proven business model, namely the design, manufacturing, and sale of aircraft. In addition, Eve will also provide Services & Support on an agnostic basis worldwide. With that, Eve is uniquely positioned to serve its customers by leveraging Embraer’s global presence with local support. It has secured non-binding contracts for service solutions worldwide with 14 customers. These customers have placed Letters of Intent (LOI) for approximately 1.1k of our eVTOLs, or 41% of our order book. These contracts include Maintenance, Repair and Overhaul, training, battery services, data integration, spare parts solutions, and component repair. A Memorandum of Understanding (MOU) signed with DHL Supply Chain will enhance these functions by optimizing the 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 services contracts are expected to bring potential revenues of $1.6 billion during the first few years of vehicle operation. Because of our agnostic approach to the maintenance business, Services & Support revenues could precede the first delivery of our eVTOL. Lastly, in addition to eVTOL sales and TechCare, Eve is developing Vector and has signed LOIs from 21 customers globally.

Eve’s eVTOL concept and design Rather than relying on traditional combustion engines, eVTOL aircraft are designed to use electric motors, providing an alternative means of transportation in urban markets that do not produce carbon emissions. Eve’s design uses a conventional fixed wing and empennage, rotors, and a pusher, giving it a practical and intuitive lift-plus-cruise design that favors safety, efficiency, reliability, and certifiability while being environmentally friendly. With an expected range of 60 miles (approximately 100 kilometers), Eve’s aircraft can offer a sustainable and affordable commute and reduce sound levels compared to current conventional helicopters. Its human-centered design minimizes sound to ensure the comfort of passengers, the pilot and the community. The all-electric aircraft features dedicated rotors for vertical flight and a fixed wing for cruise flight, with no components required to change position during flight. It will be piloted at launch but evolve towards uncrewed operations in the future.

Non-GAAP Financial Measures (Unaudited) Management uses both generally accepted accounting principles (GAAP) and non-GAAP financial measures to assess the financial condition of the Company. Management believes certain non-GAAP measures described below provide investors with additional insight into the Company’s ongoing business performance and financial condition. These non-GAAP measures should not be considered in isolation or as a substitute for the related GAAP measures, and other companies may define such measures differently. Investors are encouraged to review the Company's financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. Free Cash Flow is a non-GAAP measure and is used to review and measure the Company's capital resources against the substantial cash requirements for operations, which can be useful for an investor to assess the Company's liquidity position or needs. Its most comparable GAAP measure is Net Cash used by operating activities. Free Cash Flow is calculated as net cash used by operating activities reduced by expenditures for PP&E, as provided in the “Key Financial Indicators” table on page 1. Management also uses a non-GAAP measure called "total liquidity" to track the Company’s access to capital resources. Total liquidity is defined and measured as the sum of cash and cash equivalents, financial investments, related party loan receivable, and available debt. Cash equivalents include deposits in bank deposit certificates issued by financial institutions in Brazil that are immediately available for redemption and fixed term deposits in US Dollars with original maturities of 90 days or less. Financial investments include debt securities with maturities greater than 90 days but less than 365 days. The remaining borrowing availability from the BNDES loans is fully committed to the Company. The following table reconciles total liquidity used by management: Total Liquidity (Unaudited, US dollars, millions) Cash Flow (Unaudited, US dollars, millions) March 31, 2025 December 31, 2024 Cash and Cash Equivalents $ 59.5 $ 56.4 Financial Investments 228.1 247.0 Available undrawn debt facilities 122.7 125.2 Total Liquidity $ 410.3 $ 428.6 Net cash used by operating activities $ (24.9) $ (35.8) Net cash provided (used) by investing activities $ 18.5 $ (2.1) Net cash provided by financing activities $ 9.3 $ 14.7
