PROSPECTUS SUMMARY

This summary provides a brief overview of information contained elsewhere in this prospectus. Because it is abbreviated, this summary does not contain all the information that you should consider before investing in our Class A common stock. References in this prospectus to “BETA,” the “Company,” “we,” “us,” “our” and like terms are to BETA Technologies, Inc., a Delaware corporation, and its wholly owned subsidiaries, unless the context otherwise requires or we otherwise state. Certain terms used in this prospectus are defined in the section titled “Commonly Used Defined Terms.” You should read the entire prospectus carefully before making an investment decision, including the information presented under the headings “Risk Factors,” “Cautionary Note Regarding Forward-Looking Statements” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the historical financial statements and related notes thereto included elsewhere in this prospectus.

Our Company

We are redefining the aerospace industry. We have developed an electric aircraft platform and propulsion systems that are positioned to transform the aviation industry forward into a new phase of growth. We design, manufacture and sell high-performance electric aircraft, advanced electric propulsion systems, charging systems and components. Further, we have invested in the underlying infrastructure of this breakthrough technology, which is critical to bringing electric aviation to life. We believe we have developed a differentiated presence in North America and are well positioned to expand globally.

Our company was purpose-built to capture the significant, untapped market opportunity in sustainable, reliable and efficient electric aviation.

Vertical integration allows us to innovate rapidly and capture meaningful economic value throughout an aircraft’s lifetime by providing batteries and aftermarket services for BETA aircraft and other customers. Our focus is on the Enabling Technologies essential to electric aviation, including batteries, motors, flight control systems and a nationwide network of electric charging and related equipment. With proprietary control over these core technologies, we offer customers a complete platform to support their adoption of electric aircraft to enable both existing and new missions. This multilayered approach provides us with recurring, high margin opportunities.

We have developed highly scalable technologies that can be tailored to, and deployed for cost-effective and safe missions across cargo and logistics, defense, passenger and medical end markets. Our simplified approach to designing electric aircraft allows us to service a variety of end markets and mission types leveraging the same core technologies. The portability of our technologies and systems across various aircraft also unlocks flexibility to innovate on future generations of aircraft.

We are pursuing a stepwise approach to growing our business in both certification and market entry. We believe this significantly derisks our business model and expands our addressable market. This approach creates a logical progression where each certification effort informs the next—streamlining documentation, building continuity with FAA personnel, and reducing risk across programs.

Our go-to-market strategy is also incremental over time. We intend to prioritize cargo and logistics, while also giving focus to military applications and medical industries, before delivering aircraft to passenger operators.

We believe our ALIA CX300 (the “CX300”) electric aircraft is at the forefront of the electric aviation industry. The ALIA CTOL has successfully flown thousands of flights, over 80,000 miles, including operations in North America and Europe. This includes the world’s first, all-electric passenger flights into John F. Kennedy International Airport, which utilized approximately $7.00 in flight fuel costs, demonstrating electric aircraft’s integration into congested national airspace and approximately 95% in fuel cost savings when compared to a combustion aircraft based on internal estimates. Our CX300 also made its debut at the Paris Air Show in June 2025 opening the show with an aerial ballet demonstrating the performance and agility of our electric aircraft.

##### Table of Contents

Further, our aircraft has been used by the U.S. military in training missions and flown by the FAA, providing us with valuable data with respect to our aircraft and our certification strategy. We have also completed successful missions with the DoD and cargo and logistics and medical partners and customers such as UPS and United Therapeutics Corporation (“United Therapeutics”).

We believe our aircraft represents a significant cost efficiency advantage, as total operating costs are 42% lower compared to new traditional conventional aircraft based on internal estimates. This reduction is primarily attributed to the substantially reduced maintenance requirements given our simplified aircraft design. Our aircraft’s design eliminates the need for complex components such as gear boxes, in-flight liquid cooling systems, and thrust vectoring mechanisms, further streamlining maintenance operations and contributing to lower operational costs. We believe the operating savings are even higher when comparing our eVTOL variant relative to traditional helicopters.

We believe we are the first electric aircraft OEM with a scale production facility, and we have room to grow. Our approximately 188,000 square foot Vermont production facility is designed to support production of more than 300 aircraft annually at maturity through optimized processes and manufacturing flows. We have site control and permits for expansion to over 355,000 square feet to accommodate significant future growth.

Key and Enabling Technologies employed on the BETA Aircraft.

Our Business Model

Our business model contemplates four key revenue streams:

(1) | selling aircraft to military and commercial customers such as UPS, Air New Zealand and United Therapeutics;

(2) | selling replacement batteries to operators in the aftermarket;

(3) | selling propulsion systems as a merchant supplier to other eVTOL manufacturers such as Textron eAviation; and

(4) | selling GSE, primarily chargers, to state governments, operators, Fixed Base Operators and other electric aviation companies.

Our market-entry strategy for our aircraft is initially focused on selling to operators that specialize in cargo and logistics, military and medical operations, before expanding into delivery of aircraft to customers for passenger operations. That said, our financial opportunity is maximized over the entire lifetime of the aircraft. For example, if operated for 20 years, we estimate a typical electric aircraft will require 18 to 20 sets of replacement batteries, generating approximately $13 million in revenue assuming replacement of batteries for all customer use cases every year at current year pricing levels with a 2.5% annual escalation. We believe there are customers who will easily meet this utilization.

Further, our customers will also benefit from improving battery technology over the lifetime of the aircraft, as replacement batteries are expected to deliver superior aircraft performance due to improved energy density, which directly translates into longer range and higher speeds. We believe our ownership of the battery pack technology, protected by an extensive portfolio of intellectual property, will allow us to recognize substantial recurring revenue, even after the initial aircraft sale, contributing a majority of the lifetime revenue at attractive margins.

As a merchant supplier, we leverage our technical advantage in selling propulsion systems, core components and charging infrastructure to others in the aerospace and marine industries.

##### Table of Contents

We are also developing a fully-integrated, digital platform, “Operate,” with access to real-time data from our aircraft and GSE to optimize our customers’ operational capabilities. This system enables end-to-end visibility and control over their electric aircraft fleets, including real-time flight monitoring and charging infrastructure management, AI-powered predictive maintenance and network planning, and battery health and operating cost optimization. Our digital platform also drives regulatory compliance through automated maintenance record synchronization and offers seamless integration with existing aviation systems through universal API access.

We are developing Operate in four modules: Maintenance, Control Center, Network and Data. The Maintenance module launched in July 2025 and is in active use to track maintenance on the four aircraft currently in the field, with Bristow and Air New Zealand expected to use it during operational trials. Development of the integrated Control Center module is underway, with limited functionality already in use, and an initial commercially viable version targeted by the first half of 2026. The Network and Data modules remain in planning, with availability expected prior to aircraft certification, currently targeted for late 2026.

Finally, our business model capitalizes on a fundamental element of electric mobility. Electric aircraft need electric charging. To this end, we have developed a series of charging infrastructure, including large charge cubes designed for stationary charging, mini cubes designed for more mobile applications and thermal management systems, which cool batteries during high-speed charging. Our charging products and infrastructure are designed to use the Combined Charging System (“CCS-1”) charging protocol, allowing for charging access for both electric aircraft and ground vehicles. Through a series of customer and government investments, we have built a charging infrastructure for all electric aircraft operators to use nationwide.

Our Products

We develop electric aircraft, their critical systems and components (such as motors and batteries) and GSE to charge them. We believe this enables our customers to complete all-electric, cargo and logistics, medical transport, and passenger missions at lower operating costs.

ALIA CTOL CX300 (Piloted, Electric)

ALIA CTOL (CX300) – Designed for all-weather deployment and reliability, our CTOL aircraft transports six people or 200 cubic feet of cargo plus two crew members on missions of up to approximately 215 nautical miles. This aircraft is intended to leverage existing airport infrastructure and fly in accordance with existing procedures to enable rapid adoption. We are targeting FAA Part 23 certification at the end of 2026 or early 2027. Our Backlog for the CTOL consists of 331 units, of which 131 units are for Firm Orders and 200 units are for Options. Examples of key CTOL launch customers include Air New Zealand and United Therapeutics, highlighting the versatility of the aircraft. We have not yet delivered any certified aircraft, and therefore, no associated revenue has been recognized.

ALIA VTOL A250 (Piloted, Electric)

ALIA VTOL (A250)– The ALIA VTOL (A250) is a vertical takeoff and landing aircraft, allowing it to operate from locations with or without runway access. We believe our simple and efficient design differentiates us from others in the industry – enabling a clear path to certification, lower operating costs, high reliability and class-leading range and payload.

Our Backlog for the ALIA VTOL consists of 560 units, of which 158 units are for Firm Orders and 402 units are for Options, with a goal of achieving type certification (“Type Certification”) towards the end of 2027 or early 2028. Our order book highlights the broad capabilities of our aircraft across: cargo and logistics, including orders from UPS and Bristow; medical operations, including orders from Metro Aviation and New Zealand Air Ambulance; and passenger operations, including orders from Blade and FlyNYON. We have not yet delivered any certified aircraft, and therefore, no associated revenue has been recognized.

ALIA Defense VTOL MV250 (Autonomous, Hybrid)

ALIA Defense VTOL (MV250) – The MV250 is the military variant of our VTOL aircraft and draws heavily from the ALIA platform. The capability specifications from our cargo and logistics customers stack up closely with specifications from the U.S. military for their next generation aircraft, including capabilities such as long range, low heat/noise signature operations and the potential to operate autonomously. The specifications from these customers, which we expect to be able to deliver, are for a vertical takeoff and landing aircraft that can carry up to one ton (approximately 2,000 pounds) 250 nautical miles, which is priced between $5-10 million, and has operating cost benefits over existing aircraft models.

We expect multiple military branches to use ALIA defense VTOLs in their operations. We remain a candidate for the USMC’s Aerial Logistic Connector program which seeks to fill the large size class contested logistics. Additionally, the Army established the Contested Logistics Cross-Functional Team under Army Futures Command to generate requirements that will drive future programs of record.

We are also partnering with General Electric Company, operating as GE Aerospace (“GE Aerospace”), to co-develop a hybrid electric turbogenerator, specifically designed for defense and civil applications. In conjunction with the partnership, GE Aerospace is making an equity investment of $300 million in BETA. This collaboration is poised to enhance our offerings by integrating hybrid electric capabilities, which are critical to modern defense applications. The new turbogenerator technology, we believe, can deliver multiple advantages, including longer range, higher speed, reduced operating costs, and increased payload capacity. Our joint efforts signify a strategic advancement in leveraging hybrid electric propulsion systems, meeting the stringent demands of both defense operations and commercial aviation. This partnership reflects our commitment to adopting cutting-edge technology for sustained growth and operational efficiency.

The certification process for defense aircraft is different from the FAA civil aircraft certification process in that standards of safety and performance are applied to aircraft based on the intended mission and level of safety required to perform the intended mission for the DoD; in many cases offering reduced requirements than the FAA. Due to the variety of mission cases the MV250 has the potential to serve, the requirements for and timeframe in which it is approved for military service remains to be defined. Separately, the DoD has the ability to operate the aircraft for a subset of test and demonstration missions prior to obtaining formal approval.

##### Table of Contents

Larger Aircraft – We are in the development phase of a larger aircraft initially designed to carry up to 19 passengers. We are able to move rapidly by leveraging our existing technologies and experience from existing aircraft. We believe this product will further expand our market share by creating new opportunities for operators to realize the benefits of electric aviation in large aircraft. The timeline for obtaining civil certification of the larger commercial airplane has yet to be determined.

Motors

H500A Motor (L) and V600 Motor (R)

The H500A motor leads the industry both in terms of maximum power output and power-to-weight ratio, weighing only 165 pounds while providing 573 horsepower based on internal testing. We believe this leadership position is achieved through a simple design that is free of heavy liquid cooling systems and complicated assemblies – allowing for 97.5% efficiency based on internal testing. The H500A features dual redundancy and significantly fewer parts than a comparable legacy aircraft engine. Our design philosophy of the H500A lends itself to easy adaptation into the more powerful H500B variant and V600A vertical lift motor, both currently in development.

7

##### Table of Contents

We sell our motors to both established aerospace and defense OEMs, as well as new market entrants designing electric aircraft. Our electric motors have aerospace and marine applications that require high reliability with significant power in a small package. As an example, we have a subcontract with General Dynamics Applied Physical Sciences, manufacturing and delivering hardware and associated engineering services, in support of a Defense Advanced Research Projects Agency (“DARPA”) program focused on developing advanced propulsion technology for undersea vehicles. These opportunities represent both initial sales and long-term recurring revenue when motors require maintenance or replacement in the aftermarket.

In July 2025, the Hartzell Propeller received FAA Part 35 Type Certification, becoming the first propeller the FAA has certified for any electric aircraft. This milestone serves as a stepping stone for obtaining Type Certification by the FAA for the H500A under Part 33 given the parallels between FAA Part 35 Type Certification, which governs propeller certification, and FAA Part 33, which governs airworthiness standards for engines.

We are targeting Type Certification by the FAA for the H500A under Part 33 in late 2025 or early 2026. A Part 33 certification will enable easier integration of the H500A on to Part 23 aircraft.

Batteries

Batteries

Electric aircraft require batteries, and we are operating with today’s battery capabilities. We purchase battery cells and integrate them into a proprietary module and pack assembly designed with features to deliver safer energy across multiple aircraft and non-aircraft platforms. Our batteries contain redundant protections against unlikely thermal runaway events, communication issues or non-uniform discharges. The packs we deliver meet stringent industry-standard regulatory requirements. The frequency of replacement can depend on various usage conditions, but we estimate the majority of customers will need to replace batteries every 12-24 months.

Charging Products

As of August 31, 2025, we have commissioned 51 high-speed airport charging stations capable of recharging our ALIA CTOL or VTOL aircraft in as little as 20-40 minutes for average flights. This network has been funded almost entirely, by our customers and industry peers. Additionally, we have installed the first electric aircraft charger on a U.S. military base at Duke Field, which is part of the broader Eglin Air Force Base complex.

Large, Untapped Market Opportunity

We define our market opportunity in terms of our total addressable market (“TAM”), which is calculated based on the potential for new aircraft sales for commercial and defense applications, in addition to the lifetime revenue of potential aftermarket components and services. The aftermarket components and sales include batteries, motors, other components, maintenance, training and charging solutions.

We estimate the TAM for electric/hybrid aircraft to consist of approximately 60,000 units with an assumed value of $250 billion, using an average selling price of approximately $4 million per unit, through 2035. This is based on internal calculations derived from publicly available information and an analysis conducted by a global third-party consulting firm, not commissioned by us, which focused on passenger use cases. In addition, we have included incremental cargo, medical, defense and passenger use cases based on our market analysis and experience. We have further excluded certain geographic and aircraft use cases that are outside the scope of our intended business model. In addition to initial aircraft sales, we believe that each aircraft represents an estimated three times in incremental aftermarket revenue opportunity throughout its life, for an approximate value of $750 billion. We have developed CTOL and VTOL aircraft which can serve both commercial and end markets, cargo and logistics and passenger applications, to maximize the potential TAM.

Total Product Lifecycle

We believe that each aircraft we sell presents a larger long-term service and aftermarket revenue opportunity for additional value capture over a 20-year period.

As our global aircraft fleet grows, replacement batteries and maintenance requirements are also expected to grow. To support growing fleets of electric aircraft, charging infrastructure will be required at airports and vertiports globally.

In aviation, most maintenance requirements are recurring and non-deferrable, even during periods of economic downturn or reduced demand for commercial air travel.

We primarily compete across four end markets within the aerospace industry: cargo and logistics, medical, defense and passenger.

Cargo and Logistics: We believe cargo and logistics represent a near-term, sizable and compelling opportunity for our aircraft and products. Based on the demand for timely supply chain solutions caused by the rise of e-commerce, large global parcel and e-commerce companies have tested and placed orders for electric aircraft and drones to address supply chain constraints. In 2024, e-commerce made up approximately 16% of total retail sales in the United States based on the U.S. Census Bureau, 2024 Annual Retail Trade Survey. In parallel, customers are increasingly demanding faster delivery times, pressuring traditional distribution networks. The introduction of electric aircraft in cargo and logistics, specifically in rural areas, received additional support in the June 2025 Executive Order entitled “Unleashing American Drone Dominance” (the “June 2025 Executive Order”). Customers including UPS and Bristow have placed Firm Orders.

Medical: Electric aviation, both CTOL and VTOL, are well-suited to meet the growing demand for fast, reliable and environmentally sustainable healthcare logistics. Our aircraft are uniquely suited for medical operations with their large and flexible interior spaces. Lower operating costs of electric aircraft make them

11

##### Table of Contents

well-suited for Medical Cargo and Low-Acuity Patient Transfer missions. Customers including United Therapeutics, Metro Aviation and New Zealand Air Ambulance have placed Firm Orders.

Defense: Our ALIA platform is well suited for emerging necessities of modern warfare in both their low maintenance burden and their autonomy-ready designs. Current events and conflicts across the globe have resulted in increased defense and national security spending, both nationally and internationally. Existing defense logistics platforms, mainly helicopters, are poorly suited for imminent threats, including conflicts across wide expanses of ocean. In the United States, defense and national security spending benefits from strong bi-partisan support, which has resulted in a stable and growing investment over time. Our demand forecast consists of nearly 2,000 BETA aircraft for defense applications through 2035 based on DoD estimates and internal opportunity sizing. We believe the increased focus on lower cost, attributable and, where possible, dual-use technology that can be rapidly produced, will benefit us and aligns with our key focus areas.

Passenger: We believe that the demand for urban and regional air mobility services will usher in a new wave of growth for the commercial aerospace market. Based on 2024 schedule data, 20% of flights globally are under 300 miles, demonstrating this trend. As traditional, ground-based transportation alternatives become increasingly expensive and population growth accelerates, their scalability is becoming highly questionable. At the same time, technological advances in battery energy density, propulsion, design and materials are enabling aircraft to serve shorter distances in a more cost-effective and environmentally sustainable manner. The convergence of these forces has led airlines, aircraft lessors and charter companies to place orders for over ten thousand aircraft worth over $80 billion. We expect these trends to continue and create new opportunities to convert terrestrial transportation demand to aircraft.

Our Competitive Strengths

Simple Design along with a Strategic, Stepwise Approach to Derisk the Certification Process

Our certification strategy is purpose-built to advance new technology through a staged roadmap that we believe aligns with the FAA’s safety mission of “building confidence instead of friction.” This strategy advances our guiding principle, “safety through simplicity.” For example, if a component, joint or moving piece is not needed for safety on the aircraft—it is not on the aircraft. This clarity and decisiveness saves us a significant amount of time and effort as we seek certification across our product suite. In July 2025, the Hartzell Propeller received FAA Part 35 Type Certification, becoming the first propeller the FAA has certified for any electric aircraft.

We are taking a pragmatic approach that aligns with FAA frameworks, de-risks certification timelines and lays a scalable foundation for broader market success. This stepwise approach creates a logical progression where each certification effort informs the next — streamlining documentation, building continuity with FAA personnel and reducing risk across programs. Our market entry strategy mirrors this discipline by beginning with cargo and logistics and medical applications—lower-risk, high-value missions that can enable early revenue, generate real-world safety data and foster public trust ahead of passenger operations.

We are leaders in shaping policy through FAA collaboration and contributions to the development of policy needed for innovative technologies. We believe that we have built a trusted, influential relationship with the agency across all levels, enabling us to help shape regulation and accelerate progress first for BETA and thereafter for the entire industry.

In July 2025, the FAA released Advisory Circular (AC 21.17-4), which covers type certification of powered-lift aircraft and sets out the requirements for airworthiness approval of eVTOL vehicles. Previously, eVTOL developers engaged with the FAA on an individual basis to agree on the G-1 certification basis for their aircraft, including a lengthy public comment process. In BETA’s case however, pursuant to AC 21.17-4, we were

12

##### Table of Contents

able to adopt the AC requirements as our certification basis, accelerating our path to certification. In August 2025, we closed our G-1 certification basis following the submission of our Stage 3 response to the FAA. Due to negotiations with the FAA and our advocacy for streamlined requirements that are optimized for our aircraft configuration within the final Advisory Circular, we were able to secure favorable certification requirements that are closely aligned with the Special Federal Aviation Regulation (“SFAR”) adopted by the FAA in December 2024.

Certification Pathway

Vertically-Integrated Aerospace Company Developing the Core Technologies that Enable the Emerging Electric Aviation Ecosystem

We control and make proprietary batteries, motors, FBW systems and software for our aircraft. These core technologies are sought after by leading aerospace incumbents, further validating the demand for our products.

Our vertical integration facilitates improve collaboration and communication across different stages, through our “approve then improve” strategy. We prioritize rigorous design, manufacturing, and testing protocols to ensure the highest quality products. This integration supports our ability to adapt swiftly to design and product changes, ensuring that we remain competitive and responsive to our customers’ needs.

Our vertical integration allows for rapid iteration in the design and manufacturing process of our aircraft. The physical proximity of our R&D, manufacturing and testing facilities allows for faster collaboration and

13

##### Table of Contents

increased efficiency compared to a process reliant on many external suppliers. The capital investment in extensive manufacturing space enables us to scale to a rate of 300 aircraft per year at maturity, and we have site control for additional expansion. Further, our aircraft production lines are designed with the capability to produce both the CX300 and A250 aircraft on the same tooling. Common part applications across our aircraft programs, such as engines, batteries, FBW controls, avionics and landing gears, enable streamlined manufacturing processes and maximize operational efficiency.

Cargo and Logistics First Approach to Provide Nearer Term Market Entry

Our cargo and logistics ALIA CTOL facilitates early market entry. The cargo and logistics ALIA CTOL relies on standing rules and infrastructure to tap into an existing and growing logistics market. The demand from cargo and logistics and medical logistics operators is demonstrated by existing Backlog orders. Our CTOL aircraft easily integrates into the nation’s airspace and procedural landscape. Electric charging systems are the only additional infrastructure required, which we have been building for several years. We believe certifying our cargo and logistics ALIA CTOL airplane under FAA’s Part 23 relies on established rules to unlock revenue through the sale of type certified aircraft.

We believe the benefits of our cargo and logistics first approach will flow through to support the rapid progression of the passenger ALIA CTOL, along with all our ALIA VTOL programs. We expect to collect valuable operational data and flight experience through the use of our cargo and logistics ALIA CTOL by logistics and medical customers. We believe this data and experience will support passenger variant entry into service with a track record of safety and operational successes. It further allows us to continue building the infrastructure necessary to support our passenger customers’ urban and regional operations.

Our strategy carries across both our ALIA CTOL and VTOL platforms. Each aircraft is expected to enter service under a Type Certification for cargo and logistics operations first, followed by a passenger configuration through an amended Type Certification process. The significant similarity across the ALIA platform will ease the FAA’s Type Certification amendment process. As the only electric aircraft manufacturer with a clear cargo and logistics go-to-market strategy, we believe that we are well positioned to benefit from the rural logistics-focus of the June 2025 Executive Order – particularly in its directive for the FAA to allow the commercial use of electric aircraft prior to Type Certification.

Aftermarket-focused Business Model that Targets Recurring Revenue over Full Aircraft Lifetime

Our business strategy centers around leveraging aircraft sales to generate extensive recurring revenue at attractive margins over the lifetime of each aircraft. We plan to provide essential support throughout the operational lifespan of our aircraft, seeking to ensure continuous performance, safety and reliability. Our strategy prioritizes establishing diversified and consistent recurring revenue streams, servicing batteries, charging, maintenance and parts, creating a compelling opportunity for long-term profitability.

Battery replacements alone are expected to exceed the initial revenue from selling individual aircraft and provide higher margins. In a dynamic unique to electric aviation, replacement battery packs have the opportunity to increase the range of existing aircraft – increasing their utility.

Beyond BETA-built aircraft, selling our motors, batteries and other aircraft components to others extends our ability to leverage aftermarket recurring revenue at attractive margins.

Our Growth Strategy

We intend to pursue the following strategies to realize meaningful growth across our business.

Leverage Diverse Customer and Strategic Relationships for Expanded Market Aperture

Our leadership position in the technologies required for electric aviation is actively reinforced through strategic partnerships and/or orders from the strongest players in their respective industries including General Dynamics, Applied Physical Sciences, Textron eAviation, United Therapeutics and UPS. We will continue to collaborate closely with our customers and partners, seeking to ensure that our technologies are suited for an expanding aperture of market demand and industry trends. Beyond the United States, we have line-of-sight to serving considerable international demand in both civil and defense sectors.

Built on both our expertise and the trust of established aircraft manufacturer, to date, we have secured nearly $60 million in both Firm Orders as well as sales orders of our Enabling Technologies – all of which are protected by our growing portfolio of 447 patents as of August 31, 2025, the earliest expiration date of which is 2040 if all maintenance fees are paid. We intend to further expand our network of customers by continuing to provide world-class technologies in the form of products that make safe, cost-effective electric aviation a reality.

Obtain FAA Type Certification in the U.S. and Then Seek Validation with EASA and Other Regulators

We are in the process of certifying our H500A electric motor (FAA Part 33), ALIA CTOL (CX300) airplane (FAA Part 23), and ALIA VTOL (A250) aircraft (FAA Part 21.17(b)). We also maintain relationships with all major civil aviation authorities to enable validation as our international footprint expands. Early engagement with EASA is currently underway to provide initial awareness of our platforms. After FAA certification is secured for each Type Certification program, we plan to pursue validation with Transport Canada and CAA New Zealand to support existing international customers. We believe we will be able to achieve applicable additional verifications post FAA certification. These efforts align with our commitment to meet global regulatory standards and deliver certified aircraft across key markets.

Distribute and Advance our Technology to Deepen Trusted Partnerships with the DoD

In 2024, we obtained Facility Clearance (FCL) from the Defense Counterintelligence and Security Agency (DCSA). Our FCL supports our ability to generate and handle classified information and conduct classified work as prime and subcontractors for U.S. government contracts. Additionally, employees hold security clearance for the execution of classified contracts.

We also intend to continue to build on our successful collaboration with the U.S. Army through the Combat Capabilities Development Command (DEVCOM) to support developing requirements from the Contested Logistics CFT as well as with the U.S. Marine Corps with the Aerial Logistics Connector and Medium Aerial Resupply Vehicle—Expeditionary Logistics programs. We believe our environmentally sustainable, zero-emission electric propulsion, low heat signature technology is critical to achieving the DoD’s requirements for reduced acoustic signatures for stealth, lower operating costs and enhanced energy resilience.

Given our track record of success with the DoD, the U.S. military is exploring further opportunities with our innovative aircraft including, but not limited to contested logistics, medevac, power delivery to field units and personnel and cargo transport.

With our flight proven aircraft and GSE delivering mission critical capabilities, we continue to enable equipment and supply pre-positioning, scalable logistics packages and access to forward operating sites in dispersal operations.

Grow Base of Recurring Revenue and Profit through OEM Aircraft Lifecycle Model and Control of Infrastructure

We believe our proprietary aftermarket solutions unlock multi-year recurring revenue streams. Given the battery replacement and light service for motors over the multi-year life of each aircraft sold, we expect that our recurring revenue at attractive margins will increase over time.

We believe our ownership and control of charging equipment technologies will allow us to continue to grow the U.S. network at airports and other locations. In addition, we intend to expand this charging network globally in advance of filling sales of ALIA to our international customers.

In the traditional aircraft business model, profit generation is compartmentalized among different entities: aircraft OEMs profit from the sale of aircraft, fuel providers and Fixed Base Operators (“FBOs”) from the sale of fuel, and engine OEMs from maintenance services. In contrast, our model represents a comprehensive integration of these segments. We develop and sell the aircraft while simultaneously owning and distributing the charging infrastructure. Furthermore, we conduct all necessary maintenance, enabling us to capture value across all traditional revenue streams by consolidating these operations under one roof. We believe this integrated approach not only diversifies our revenue but also allows us to offer streamlined, efficient service to our clients, enhancing the overall value proposition of our business model.

Expand Nationwide Charging Network

We believe we are a leader in electric ground support innovation and have built the only aviation-centric charging network in the world – one that will power not only our aircraft but the emerging industry. We intend to continue to expand this network through strategic partnerships with established FBOs, reducing the regulatory burden, capital and overhead required to effectively execute. Additionally, we intend to continue to work with customers and public institutions to expand our network with minimal capital requirements. We believe this model has been successfully demonstrated through infrastructure contracts with the U.S. Department of Health and Human Services (DHS) and United Therapeutics to date.

Achieve Economies of Scale and Manufacturing Efficiencies

Our current manufacturing facility in Vermont can support the manufacturing of up to 300 aircraft per year across multiple assembly lines at maturity. These lines are purpose-built to accommodate the production of all variants of our ALIA CTOL and VTOL platforms. We possess site control and the permits necessary to expand the manufacturing facility to 355,000 square feet from approximately 188,000 square feet to support higher throughput.

As aircraft production volumes increase, we expect labor utilization and operating leverage will improve. We anticipate leveraging automation for some routine tasks. Costs of inputs can be expected to improve as we purchase larger quantities of materials from suppliers to meet added throughput. We also expect to continue to innovate aircraft structure design to reduce the cost and number of components required to build each aircraft.

Develop the Next Generation of Technology to Further Disrupt the Aerospace Industry

We intend to continue stepwise research and development of our portfolio of differentiated technologies. Centralized, modular and interchangeable parts allow for application of our patented technologies in future projects, such as our Large eCTOL aircraft, which is currently in the design phase. Our team has built a strong base of research and development and test expertise through years of developing our Enabling Technologies and ALIA aircraft that we can leverage to develop new products. First, we will build small aircraft, then we will build larger ones.

Our collaboration with the DoD offers valuable funding, expertise and test opportunities for future projects as well. For our ALIA X250 project, which will inform the final production of our MV250 military aircraft, we have received funding from the U.S. Air Force for deliverables relating to our hybrid propulsion development and the

17

##### Table of Contents

U.S. Army is actively funding deliverables related to our autonomy development for the platform, including a build-up through remote piloting. The ALIA X250 aircraft is the prototype vehicle for the MV250 product and will serve as the test bed for the hybridization and autonomous control technology which will be leveraged on the production MV250. We are currently nearing the end of a process to down-select an autonomy provider and actively continuing development on hybrid propulsion systems.

Similarly, our partnership with GE Aerospace allows us to further develop next-generation technology by combining our extensive knowledge of generators with GE Aerospace’s established engine leadership. This collaboration not only leverages our collective strengths but also positions us at the forefront of innovation in electric engine solutions, underlining our commitment to advancing sustainable and efficient next gen technology.

We intend to leverage these research and development partnerships with the military to grow towards becoming a major supplier of such technologies to the DoD.

We are continuously innovating, pushing forward the boundaries of electric aviation.

Summary of Risk Factors

There are a number of risks related to our business, this offering, ownership of our Class A common stock and our capital structure that you should consider before you decide to participate in this offering. Some of the principal risks related to an investment in our company include the following:

| • |  | Our business plan requires a significant amount of capital. We expect to require additional future funding to support our operations and implementation of our growth plans and we may be unable to access the capital and credit markets or borrow on affordable terms.

| • |  | We expect to be significantly dependent upon revenue generated from the sale of our electric aircraft, our batteries and our core technologies, along with the utilization of our charging infrastructure, and our future success will be dependent upon the continued development of the electric and hybrid electric aviation (including VTOL) industry and our ability to design and achieve market acceptance, adoption and utilization of these new technologies.

| • |  | We may experience significant delays in the design, manufacture, certification and commercial rollout of our aircraft.

| • |  | Our limited operating history makes evaluating our business and future prospects difficult and may increase the risk of your investment.

| • |  | We have incurred significant losses since inception, we expect to incur losses in the future and we may not be able to achieve or maintain profitability.

| • |  | Our long-term success and ability to significantly grow our revenue will depend, in part, on our ability to establish and expand our presence within international markets.

| • |  | The aircraft market is highly competitive.

| • |  | Crashes, accidents or incidents of electric and hybrid aircraft, as well as accidents or incidents involving battery solutions, such as lithium-ion batteries.

| • |  | We are subject to many hazards and operational risks that can disrupt our business for which we may not be able to secure adequate insurance policies at reasonable prices or at all.

| • |  | We are highly dependent on the continued service and leadership of Kyle Clark, and if we are unable to retain Mr. Clark, our ability to compete and overall performance could be harmed.

| • |  | We expect to conduct a portion of our business pursuant to U.S. government contracts, which are subject to unique risks.

| • |  | We may be subject to risks associated with our strategic relationships.

| • |  | Our current collaboration with GE Aerospace and future strategic alliances could have an adverse effect on our financial condition and results of operations.

| • |  | We enter into aerospace commercial contracts, which are subject to unique risks.

| • |  | We may not realize all of the sales expected from our Backlog.

| • |  | We are subject to customer concentration risks.

| • |  | We depend on suppliers and service partners for raw materials and certain parts and components.

| • |  | We may be unable to seek, obtain, maintain, protect or enforce our intellectual property rights, or to otherwise defend our intellectual property rights from unauthorized access or use by third parties.

| • |  | Third parties may claim that we infringe, misappropriate or otherwise violate their intellectual property.

| • |  | Interruption to, interference with, or failure of our complex information technology and communications systems could hurt our ability to effectively operate our business.

| • |  | We do not intend to pay dividends after this offering and may never do so.

| • |  | Investors in this offering will experience immediate and substantial dilution of $   per share.

| • |  | Future sales of the Class A common stock in the public market, or the waiver or early release of lock-up agreements, could reduce the market price of the Class A common stock, and any additional capital raised by us through the sale of equity or convertible or exchangeable securities may dilute your ownership in us.

These and other risks are more fully described in the section titled “Risk Factors” in this prospectus. If any of these risks actually occurs, our business, results of operations, financial condition or prospects could be materially and adversely affected. As a result, you could lose all or part of your investment in our Class A common stock.

RISK FACTORS

An investment in our Class A common stock involves a high degree of risk. You should carefully consider the risks described below before making an investment decision. Our business, results of operations, financial condition or prospects could be harmed by any of these risks, as well as other risks not currently known to us or that we currently consider immaterial. The trading price of the Class A common stock could decline due to any of these risks, and, as a result, you may lose all or part of your investment.

Certain statements in this “Risk Factors” section are forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to Our Business and Industry

Our business plan requires a significant amount of capital. We expect to require additional future funding to support our operations and implementation of our growth plans and we may be unable to access the capital and credit markets or borrow on affordable terms to obtain additional capital that we may require.

Our proposed operations and our business strategy contemplate significant manufacturing capacity and aircraft and infrastructure development, including additional vertiports where our aircraft can land, both within the United States and internationally. Construction of additional manufacturing and testing facilities, chargers and other facilities will require significant capital expenditures, as will future expansion of and improvements to our operations. Based on our recurring losses and management’s expectations that significant on-going operating expenditures will be necessary to successfully implement our business plan and develop our powerhouses, we expect to require additional funding to continue our operations through commercialization. Although we intend to partner with or pursue leasing or other arrangements with third parties in relation to certain of our facility needs, we cannot be assured that such partnership opportunities or other arrangements will be available on commercially reasonable terms, or at all.

In addition, as our facilities and aircraft mature, our business will require capital expenditures for the maintenance, renovation and improvement of such facilities to remain competitive. This creates an ongoing need for capital, and, to the extent we cannot fund capital expenditures from cash flows from operations, we will need to borrow or otherwise obtain funds.

We expect to fund our operations through equity offerings or debt financings, credit or loan facilities, potential other capital resources, or a combination of one or more of these funding sources. Such financings may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business.

Periods of instability in the capital and credit markets (both generally and those impacting the aerospace industry in particular), including as a result of global health crises or other events contributing to the disruption and volatility of global financial markets, could limit our ability to access these markets to raise debt or equity capital on affordable terms or to obtain additional financing. Among other things, our lenders may seek to increase interest rates, enact tighter lending standards, refuse to refinance existing debt at maturity on favorable terms or at all and may reduce or cease to provide funding to us. For example, increased interest rates in 2022 and 2023 led to a widespread slowdown in investment and funding opportunities, especially for pre-revenue companies. We may sell equity securities or debt securities in one or more transactions at prices and in a manner that may materially dilute our current investors. Any debt financing, if available, may involve restrictive covenants that could reduce our operational flexibility or profitability. Debt financing, if available, may result in a significant financial burden if interest rates remain high for a prolonged period or increase in the future. We expect that the net proceeds from this offering, together with our existing cash and cash equivalents, will enable us to fund our operating expenses and capital expenditure requirements for at least the next 12 months.

##### Table of Contents

However, our operating plan may change as a result of factors currently unknown to us, and we may need to seek additional funding sooner than planned. If we cannot raise funds or otherwise enter into financing arrangements on acceptable terms, we may be forced to delay, reduce, or eliminate our research and product development programs or future commercialization effort, or we may not be able to grow our business or respond to competitive pressures, any of which may have an adverse impact on our business, results of operations, financial condition and prospects.

We expect to be significantly dependent upon revenue generated from the sale of our electric aircraft, our batteries and our core technologies, along with the utilization of our charging infrastructure, and our future success will be dependent upon our ability to design and achieve market acceptance, adoption and utilization of these new technologies.

We expect to generate a significant portion of our revenue from the sale of our electric aircraft and batteries and the commercialization of our infrastructure and critical charging and software systems. While we believe we are uniquely positioned to capture revenues across the full aircraft lifecycle, from new aircraft sales for commercial and military applications to revenues from sales of related products and services, including batteries, motors, components, maintenance, training and charging solutions, each of our aircraft requires significant investment prior to commercial introduction, and may never be successfully developed or commercially successful. There can be no assurance that we will be able to design future models of electric aircraft or infrastructure and charging technologies that will meet the expectations of our customers or that our future models will become commercially viable. In particular, it is common in our industry for the production aircraft to have a styling and design different from that of the concept aircraft, which may happen with our future aircraft. As technologies change in the future for aircraft in general and electric aircraft specifically, we will be expected to upgrade or adapt our aircraft and introduce new models in order to continue to provide aircraft with the latest technology. To date, we have limited experience simultaneously designing, testing, manufacturing and selling our electric aircraft.

We may experience significant delays in the design, manufacture, certification and commercial rollout of our aircraft, which could harm our business, brand, results of operations, financial condition and prospects.

Any significant delay in the commercialization of our aircraft could materially damage our business, brand, results of operations, financial condition and prospects. Aircraft manufacturers often experience delays in the design, manufacture, certification and commercial release of new aircraft models. We may experience such delays in launching our aircraft, and any such delays could be significant.

In addition, final designs for our eVTOL and large passenger electric aircraft are still in process, and various aspects of the aircraft component procurement and manufacturing plans have not yet been determined. We are continually evaluating, qualifying and selecting our suppliers for the planned production of our aircraft. However, we may not be able to engage suppliers for the remaining materials and components in a timely manner, at an acceptable price or in the necessary quantities. In addition, we will also need to do extensive testing to ensure that our aircraft are in compliance with applicable airworthiness regulations and other applicable requirements prior to beginning mass production and delivery of the aircraft. Our plan to begin commercial production of our aircraft is dependent upon the timely availability of funds, upon our finalizing the related design, engineering, component procurement, testing, certification, build out and manufacturing plans in a timely manner and upon our ability to execute these plans within the current timeline.

The markets for our offerings are still in development, and if such markets do not materialize, or grow more slowly than we expect or fail to grow as large as we expect, our business, results of operations, financial condition and prospects could be harmed.

The markets for electric aircraft (as well as for technologies and product and service offerings relating to same) are still in development, and our success in these markets is dependent upon our ability to effectively

##### Table of Contents

design, develop, and certify electric aircraft and to market and gain traction in respect of electric aircraft utilization as a substitute for existing methods of transport, as well as the effectiveness of our other marketing and growth strategies. If our business customers, including, in the case of our defense program, government entities, do not perceive electric aircraft as beneficial or choose not to adopt electric aircraft as a result of concerns regarding safety, noise, affordability or for other reasons, then the market for our offerings may not materialize, may develop more slowly than we expect or may not achieve the growth potential we expect, any of which could harm our business, results of operations, financial condition and prospects.

Growth of our business will require significant investments in our infrastructure, technology and sales and marketing efforts, including significant expansion of our production facilities in the future. If our business does not have sufficient capital required to support these investments, our results of operations will be negatively affected. Further, our ability to effectively manage growth and expansion of our operations will also require us to enhance our operational systems, internal controls and infrastructure, human resources policies and reporting systems. These enhancements will require significant capital expenditures and allocation of valuable management and employee resources.

The electric and hybrid electric aviation (including VTOL) industry may not continue to develop, electric aircraft may not be adopted by the market, eVTOL aircraft may not be certified by government authorities or electric aircraft may not be an attractive alternative to existing modes of transportation, any of which could adversely affect our business, results of operations, financial condition and prospects.

Electric aircraft involve a complex set of technologies, which we must continue to further develop and rely on our commercial and defense program customers to adopt. However, as a prerequisite to commercializing our electric aircraft for sale to business customers or the U.S. government, we must receive requisite certifications and approvals from applicable governmental authorities. See “—Risks Related to Laws and Regulations” for a discussion of risks associated with such regulatory and related requirements. There are currently no electric aircraft certified by the FAA and operating commercially in the United States, and there can be no assurance that our design, development and certification efforts will result in our receiving FAA certification of our aircraft. In order to achieve FAA certification, the performance, reliability and safety of electric aircraft must be established, none of which can be assured. In particular, there is a risk that we will not obtain one or more certifications from the FAA that are required for ultimate commercial rollout and use of our aircraft, or that we will experience delays in receiving one or more of these certifications. Even if our electric aircraft receive Type Certification and airworthiness certificates and we receive Production Certification, aircraft operators must conform their operational authorizations to include electric aircraft, including eVTOL, which requires FAA approval of aircraft and operational procedures, and individual pilots also must be trained and ultimately approved by the FAA to fly such aircraft, which could contribute to delays in any widespread use of electric aircraft and potentially limit the number of electric aircraft operators available to purchase aircraft from or partner with us. Additional challenges to ensuring the demand for our aircraft, technologies and related services, all of which are outside of our control, include:

| • |  | market acceptance of electric aircraft, including CTOL and VTOL;

| • |  | state, federal or municipal regulations for our electric aircraft and charging infrastructure;

| • |  | necessary changes to existing airport or vertiport infrastructure to enable adoption, including installation of necessary charging, navigation, lighting and other equipment;

| • |  | ability for customers to obtain all government approvals necessary to operate our aircraft between commercially desirable origins and destinations;

| • |  | ability for customers to obtain access to economical insurance policies for operating eVTOL aircraft; and

| • |  | public perception regarding the safety of eVTOL aircraft and the resulting demand for our business customers’ services.

##### Table of Contents

There are a number of existing laws, regulations and standards that may apply to eVTOL aircraft, including standards that were not originally intended to apply to electric aircraft. The promulgation of additional federal, state and local laws and regulations that address eVTOL aircraft more specifically, such as the operational regulations, or the Special Federal Aviation Regulation (“SFAR”) adopted by the FAA in December 2024, could delay our ability to launch commercial production of our eVTOL aircraft as well as our customers’ ability to launch commercial eVTOL operations which could impact our business plans and expectations with respect to revenue from both aircraft and aftermarket components. In addition, depending on the nature of any revised or new regulations, we may need to modify our approach to certification, and we may not be able to timely comply with such regulations. Further, we have designed our aircraft to be certified under the current FAA regulatory framework. If the applicable FAA regulations are substantially changed or new regulations are adopted, we may need to modify the design of our aircraft to comply with the new regulations, which could cause us to incur significant expenses and scheduling delays in developing and commercializing our aircraft production and may impact the performance or functionality of the certified aircraft adversely, which could adversely affect our business, results of operations, financial condition and prospects. See “—Risks Related to Laws and Regulations—Failure to comply with applicable laws and regulations relating to the aerospace business in general and electric aircraft testing, certification and production specifically, could adversely affect our business, results of operations, financial condition and prospects.”

There can be no assurance that the market will accept electric aircraft, that we will be able to execute on our business strategy or that our electric aircraft or customers of our aircraft or our related or other offerings will obtain the necessary government approvals or be successful in the applicable target market or markets. There may be heightened public skepticism of this nascent technology and its adopters. In particular, there could be negative public perception surrounding electric aircraft, including the overall safety and the potential for injuries or death occurring as a result of accidents involving electric aircraft, regardless of whether any such safety incidents occur involving us. Any of the foregoing risks and challenges could adversely affect our business, results of operations, financial condition and prospects.

Our limited operating history makes evaluating our business and future prospects difficult and may increase the risk of your investment.

We are an early-stage company with limited operating history. As such, we may encounter unforeseen expenses, difficulties, complications, delays, and other known and unknown factors as we seek to a transition to a company capable of supporting commercialization. If we do not successfully address these risks, our business, results of operations, financial condition and prospects will be materially and adversely harmed. We were formed and began designing our electric aircraft in 2018.

Our revenues were $15.4 million for the year ended December 31, 2023, $15.1 million for the year ended December 31, 2024 and $15.6 million for the six months ended June 30, 2025. We have a very limited operating history on which investors can base an evaluation of our business, results of operations, financial condition and prospects. We intend in the longer term to derive substantial revenues from the sales of our aircraft.

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. In the event that 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 have incurred significant losses since inception, we expect to incur losses in the future and we may not be able to achieve or maintain profitability.

We incurred net losses of $175.6 million and $275.6 million for the years ended December 31, 2023 and 2024, respectively. We incurred net losses of $124.1 million and $158.7 million for the six months ended June 30, 2024 and 2025, respectively. It is difficult for us to predict our future operating results. As a result, our

32

##### Table of Contents

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. While we expect that our existing cash and cash equivalents, together with anticipated net proceeds from this offering, will enable us to fund our current and planned operating expenses and capital expenditures for at least the next 12 months, until such time as we can generate significant revenue, if ever, the Company expects to fund its operations through public and private financing. There is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations, if at all. Such conditions, if they continue, may raise substantial doubt about the Company’s ability to continue as a going concern. The perception that we may be unable to continue as a going concern may make it more difficult to obtain financing for the continuation of our operations on terms that are favorable to us, or at all, and could result in the loss of confidence by investors.

We expect our operating expenses to increase over the next several years as we move towards commercial launch, continue to attempt to streamline our manufacturing process, increase our flight cadence, hire more employees and continue research and development efforts relating to new products and technologies. These efforts may be more costly than we expect and may not result in increased revenue or growth in our business. Any failure to increase our revenue sufficiently to keep pace with our investments and other expenses could prevent us from achieving or maintaining profitability or positive cash flow. 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.

We have in the past and will continue to invest significant resources in developing new product offerings and exploring the application of our Enabling Technologies for other uses and those opportunities may never materialize.

While our primary focus has been on the design, manufacture and operation of our electric aircraft, we have invested in the past and will continue to invest significant resources in developing new technologies, services, products or offerings, such as those relating to the innovation and development of electric propulsion systems, charging solutions, motors and controls. However, we may not realize the expected benefits of these investments.

Such research and development initiatives may also have a high degree of risk and involve unproven business strategies and technologies with which we have limited operating or development experience. They may involve claims and liabilities, expenses, regulatory challenges and other risks that we may not be able to anticipate. We may not be able to predict whether customer demand for such initiatives will exist or be sustained at the levels that we anticipate, or whether we will generate sufficient revenue to offset any expenses or liabilities associated with these investments. For example, we plan to continue to invest resources in developing, with an eye toward ultimate commercialization, of our large passenger electric aircraft. Any such research and development efforts could distract management from current operations and would divert capital and other resources from our more established technologies. Even if we are successful in developing new products, services, offerings or technologies, regulatory authorities may subject us to new rules or restrictions in response to our innovations that may increase our expenses or prevent us from successfully commercializing new products, services, offerings or technologies and have an adverse impact on our business, results of operations, financial condition and prospects.

Our long-term success and ability to significantly grow our revenue will depend, in part, on our ability to establish and expand our presence within international markets.

Our future results will depend, in part, on our ability to establish and expand our presence within international markets. Our ability to expand into new markets involves various risks, including, but not limited to, the need to invest significant resources in such expansion, and the possibility that returns on such investments will not be achieved in the near future or at all in these less familiar competitive environments. Our ability to expand internationally will depend upon our ability to, among other things, obtain the necessary government

33

##### Table of Contents

approvals, adapt to international markets, understand the local customer base and address any unique local technological requirements. We may also choose to conduct our international business through joint ventures, minority investments or other partnerships with local companies as well as co-marketing with other established brands. If we are unable to identify partners or negotiate favorable terms, our international growth may be limited. In addition, we may incur significant expenses in advance of generating revenues, if any, as we attempt to establish our presence in particular international markets or market segments outside of aircraft sales, operating our charging network and our defense program.

Our growing charging network is subject to location-specific risks and regulatory uncertainties.

The footprint of our charging network is growing, which makes such part of our business susceptible to wide-ranging regulatory, economic, social, weather and other conditions and related uncertainties. Significant or repeated interruption or disruption in service in an airport or area where we have established charging infrastructure could have an adverse impact on our business, reputation, results of operations, financial condition and prospects. Disruption of operations at vertiports, whether caused by labor relations, utility or communications issues, power outages or changes in federal, state and local regulatory requirements could harm our business. Certain airports may regulate electric aircraft, including limiting the number of landings, banning operations or introducing new permitting requirements, which could significantly disrupt our charging operations and could, potentially, albeit indirectly, negatively impact customer demand for our aircraft.

Our competitors may commercialize their technology before us, or we may not be able to fully capture the first mover advantage that we anticipate.

While we believe we are well positioned to be the first manufacturer to achieve FAA Type Certification for an electric airplane, we expect the electric and hybrid electric aviation (including VTOL) industry to be increasingly competitive and our competitors could get to market with their eVTOL or eCTOL aircraft before or at the same time as us, either generally or in specific markets. Even if we are first to market, we may not fully realize the benefits we anticipate, and we may not receive any competitive advantage or may be overcome by other competitors. If new or existing companies launch competing solutions in the markets in which we intend to operate and obtain large scale capital investment, we may face increased competition. Additionally, our competitors may benefit from our efforts in developing customer and community acceptance of electric aircraft and its related infrastructure, making it easier for them to obtain the permits and authorizations required to certify and successfully commercialize their technology and operations.

If our current and potential competitors are larger and have substantially greater resources or are affiliated with larger companies that may allocate greater resources than we have and expect to have in the future, they may devote greater resources to the development, certification and marketing of their products and services or to offer lower prices. Our competitors may also establish strategic relationships amongst themselves or with third parties that may further enhance their resources and offerings. Some could have more experience in the electric and hybrid electric aviation (including VTOL) industry than we have, and any foreign competitors could benefit from subsidies or other protective measures offered by their home countries. If our competitors commercialize their technology before us, or if we do not capture the first mover advantage that we anticipate, it may harm our business, results of operations, financial condition and prospects.

Our future growth is dependent upon the market’s willingness to adopt electric aircraft and its supporting infrastructure, and the resulting impact of such market demand on our customers’ need for our aircraft and other offerings.

Our growth is highly dependent upon the adoption by customers of, and we are subject to an elevated risk of any reduced demand for, alternative fuel aircraft in general and electric aircraft in particular. If the market for electric aircraft and its supporting infrastructure does not develop as quickly or otherwise in the manner consistent with our expectations or those of our customers, our business, results of operations, financial condition

##### Table of Contents

and prospects will be harmed. The market for alternative fuel aircraft is relatively new, rapidly evolving, characterized by rapidly changing technologies, price competition, additional competitors, evolving government regulation and industry standards, increasingly frequent new aircraft announcements and changing demands and behaviors of customers and other stakeholders. Factors that may influence the adoption of alternative fuel aircraft, and specifically electric aircraft, include:

| • |  | perceptions about electric aircraft quality, safety (in particular with respect to battery packs, including those utilizing lithium-ion cells), design, performance and cost, especially if adverse events or accidents occur that are linked to the quality or safety of electric aircraft;

| • |  | perceptions about aircraft safety in general, in particular safety issues that may be attributed to the use of advanced technology, including aircraft electronics;

| • |  | the limited range over which electric aircraft may be flown on a single battery charge;

| • |  | the decline of an electric aircraft’s range resulting from deterioration over time of the battery’s ability to hold a charge;

| • |  | concerns about electric grid capacity and reliability, which could derail our past and present efforts to promote electric aircraft as a practical solution to aircraft which require jet fuel or aviation gasoline;

| • |  | the availability of alternative fuel aircraft, including plug-in hybrid electric aircraft;

| • |  | improvements in the fuel economy of conventional internal combustion or turbine engines;

| • |  | the availability of maintenance services for electric aircraft;

| • |  | the importance of environmental considerations to customers and other stakeholders;

| • |  | volatility in the cost of crude oil and, relatedly, aviation fuels;

| • |  | customers’ and other stakeholders’ perceptions of the dependency of the United States on oil from unstable or hostile countries;

| • |  | government regulations and economic incentives promoting fuel efficiency and alternate forms of energy;

| • |  | access to chargers, standardization of electric aircraft charging systems and customers’ and other stakeholders’ perceptions about convenience and cost to charge an electric aircraft;

| • |  | the availability of tax and other governmental incentives to purchase and operate electric aircraft or future regulation requiring increased use of nonpolluting aircraft;

| • |  | perceptions about and the actual cost of alternative fuel; and

| • |  | macroeconomic factors.

Additionally, we may become subject to regulations that may require us to alter the design of our aircraft, which could negatively impact interest in our aircraft.

The influence of any of the factors described above may cause current or potential customers not to purchase our electric aircraft, which would materially adversely affect our business, results of operations, financial condition and prospects.

Our customers’ and others’ perception of us and our reputation may be impacted by the broader industry and customers may not differentiate us from our competitors.

Customers and other stakeholders may not differentiate between us and the broader aerospace industry or, more specifically, the electric and hybrid electric aviation (including VTOL) industry. If other participants in this market have problems related to matters such as safety, technology development, engagement with certification

35

##### Table of Contents

authorities or other regulators, community engagement, security, data privacy, flight delays or customer service, such problems could impact the public perception of the entire electric and hybrid electric aviation (including VTOL) industry, including our business. We may fail to adequately differentiate our brand, our aircraft and other product offerings from others in the market which could impact our ability to attract customers or engage with other key stakeholders and have an adverse impact on our business, results of operations, financial condition and prospects.

If we are unable to keep up with advances in electric aircraft technology, we may suffer a decline in our competitive position.

It may be challenging to keep up with changes in electric aircraft technology. Any failure to keep up with advances in electric aircraft technology would result in a decline in our competitive position which could materially and adversely affect our business, results of operations, financial condition and prospects. Our research and development efforts may not be sufficient to adapt to changes in electric aircraft technology. As technologies evolve, we plan to upgrade or adapt our aircraft, charging systems and infrastructure and introduce new developments in order to continue to provide the latest technology, in particular battery cell technology. However, we may not compete effectively with our competitors if we are not able to source and integrate the latest technology into our aircraft and related components.

If we are unable to design, develop, market and sell new electric aircraft and services that address additional market opportunities, our business, results of operations, financial condition and prospects results will suffer.

We may not be able to successfully develop new electric aircraft and services, address new market segments or develop a significantly broader customer base. To date, we have focused our business on the design of high-performance electric aircraft and our Enabling Technologies that support our aircraft. We will need to address additional markets and expand our customer demographic in order to further grow our business. We have not completed the design, component sourcing or manufacturing process for our aircraft, so it is difficult to forecast their eventual cost, manufacturability or quality. Therefore, there can be no assurance that we will be able to deliver aircraft that is ultimately competitive in the electric aircraft market. Our failure to address additional market opportunities would harm our business, results of operations, financial condition and prospects.

The aircraft market is highly competitive, and we may not be successful in competing in this industry. We currently face competition from traditional aerospace companies and recent market entrants and expect to face competition from others in the future.

The worldwide aircraft market, particularly for alternative fuel aircraft, is highly competitive today and we expect it will become even more so in the future. With respect to our aircraft, we currently face strong competition from established electric aircraft manufacturers and recent market entrants who are also developing electric aircraft. Furthermore, electric aircraft have already been brought to market in China and may be brought to market in other foreign countries in the near-term.

Many of our current and potential competitors have significantly greater financial, manufacturing, marketing and other resources than we do and may be able to devote greater resources to the design, development, manufacturing, distribution, promotion, sale and support of their products. Our competitors may be in a stronger position to respond quickly to new technologies and may be able to design, develop, market and sell their products more effectively.

We expect competition in the electric and hybrid electric aviation (including VTOL) industry to intensify in the future in light of increased demand for alternative fuel aircraft, continuing globalization and consolidation in the worldwide aircraft industry. Factors affecting competition include product quality and features, innovation

36

##### Table of Contents

and development time, pricing, reliability, safety, fuel economy, customer service and financing terms. Increased competition may lead to lower aircraft unit sales, which may adversely affect our business, results of operations, financial condition and prospects. Our ability to successfully compete in our industry will be fundamental to our future success in existing and new markets and our market share. There can be no assurances that we will be able to compete successfully in our markets.

Demand in the electric and hybrid electric aviation (including VTOL) industry is highly volatile.

Volatility of demand in the electric and hybrid electric aviation (including VTOL) industry may materially and adversely affect our business, results of operations, financial condition and prospects. The passenger, military and logistics end markets in which we primarily compete and plan to compete in the future have been subject to considerable volatility and unpredictability with respect to demand in recent periods. Demand for electric and hybrid electric (including VTOL) aircraft sales and related products, technologies and services depends to a large extent on general, economic, political and social conditions in a given market and the introduction of new aircraft and technologies. As a new aircraft manufacturer and low volume producer, we have fewer financial resources than more established aircraft manufacturers to withstand changes in the market and disruptions in demand. As our business grows, in addition to macroeconomic factors, economic conditions and trends in other countries and regions where we sell our aircraft will also impact our business, results of operations, financial condition and prospects. Demand for our electric aircraft may also be affected by factors directly impacting aircraft price or the cost of purchasing, operating, charging and maintaining aircraft (including the availability of financing and other incentives), prices of raw materials and parts and components, cost of fuel and governmental regulations, including tariffs, import regulation and other taxes. These effects may have a more pronounced impact on our business given our relatively smaller scale and financial resources as compared to many incumbents, and in particular, traditional, aircraft manufacturers.

Crashes, accidents or incidents of electric and hybrid aircraft, as well as accidents or incidents involving battery solutions, such as lithium-ion batteries, could have a material adverse effect on our business, results of operations, financial condition and prospects.

The operation of aircraft is subject to various risks, and demand for air transportation of persons as well as cargo, including in connection with our commercial offerings and defense program, has been, and may in the future be, impacted by accidents or other safety issues regardless of whether such accidents or issues involve any electric aircraft of ours. Air transportation hazards, such as adverse weather conditions, fire and mechanical failures and incidents caused by human error may result in death or injury to personnel and passengers or harm to property, which could impact customer or passenger confidence in a particular aircraft type or the air transportation services industry as a whole and could lead to a reduction in passenger or cargo volume. Safety statistics for air travel are reported by multiple parties, including the Department of Transportation and National Transportation Safety Board, and are often separated into categories of transportation. Because our commercial offerings and defense program may include a variety of transportation methods, fliers may have a hard time determining how safe electric aircraft and related products and services are and their confidence in electric aircraft and such products or services may be impacted by, among other things, the classification of accidents in ways that reflect poorly on electric aircraft and such products or services.

Test flying prototype aircraft is inherently risky, and crashes, accidents or incidents involving our aircraft, or other companies’ prototype aircraft that may utilize our products, are possible. Whether or not it involves our aircraft or our related technology, any such occurrence in the future could negatively impact our development, testing and certification efforts, and could result in re-design, certification delay and/or postponements or delays to our commercial launch.

We expect demand for our aircraft and other offerings (and, in some contexts, others’ services utilizing the same) to be impacted by accidents or other safety issues regardless of whether such accidents or issues involve

37

##### Table of Contents

our aircraft. Such accidents or incidents could also have a material impact on our ability to obtain or maintain airworthiness authorization with regulators, including the FAA, for our aircraft and could impact confidence in our aircraft type or the electric industry as a whole, particularly if such accidents or incidents were due to a safety fault or oversight.

We believe that safety and reliability are two of the primary attributes our potential customers consider when selecting a provider of electric aircraft or related products or services. Any failure by us to maintain standards of safety and reliability that are satisfactory to our customers, their clients or other end users could adversely impact our ability to attract and retain customers. We believe that regulators and the general public are still forming their opinions about the safety and utility of aircraft that are highly reliant on lithium-ion batteries and advanced flight control software capabilities and that operate in and around urban areas, among other things. An accident or incident involving either our aircraft or a competitor’s aircraft while these opinions are being formed could have a disproportionate impact on the longer-term view of the emerging market for electric and hybrid electric (including VTOL) aircraft.

We are at risk of adverse publicity stemming from any public incident involving us, our people or our brand. Such an incident could involve the actual or alleged behavior of our employees, contractors or partners. Further, if our electric aircraft, whether operated by us or a third party, were to be involved in a public incident, accident, catastrophe or regulatory enforcement action, we could be exposed to significant reputational harm and potential legal liability. The insurance we carry may be inapplicable or inadequate to cover any such incident, accident, catastrophe or action. In the event that our insurance is inapplicable or inadequate, we may be forced to bear substantial losses from an incident or accident. Any such incident, accident, catastrophe or action involving our electric aircraft or electric aircraft generally could create an adverse public perception, which could harm our reputation, result in customers, passengers or other end users being reluctant to use our products or services, and adversely impact our business, results of operations, financial condition and prospects.

Additionally, the battery packs that we sell, and that are expected to power our electric aircraft, use battery (including lithium-ion) cells. On rare occasions, battery cells, including 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 cells. It is possible that a field or testing failure of our aircraft could occur in the future, which could subject us to lawsuits, environmental, health and safety – (“EHS”) related liabilities, product recalls or redesign efforts, any of which would be time-consuming and expensive. Also, negative public perceptions regarding the suitability of battery (including lithium-ion) cells for aerospace applications or any future fire or other incident involving battery cells could seriously harm our business. Moreover, any such failure of or otherwise in relation to a competitor’s electric aircraft may cause indirect adverse publicity for us and our aircraft. Such adverse publicity could negatively affect our brand and harm our business, results of operations, financial condition and prospects.

We store batteries, including lithium-ion batteries, at our production and testing facilities. Such storage and the handling of batteries and battery materials in connection with our research and development and other business activities poses risks. For example, in August 2022, we experienced a thermal runaway fire event with respect to one of our battery packs awaiting testing, and while such incident did not have a significant impact on our business operations or certification timing, any occurrence in the future of a similar incident or other fire involving or relating to our batteries could negatively impact our development, testing and certification efforts and could result in re-design, certification delay and/or postponements or delays in respect of our commercialization timeline. In addition, our manufacturing partners and suppliers are expected to store a significant number of batteries, including lithium-ion batteries, at their facilities. Any unanticipated use, or use beyond the scope of recommended parameters, in the transport, testing, storage or other use of battery cells, including lithium-ion cells, may cause disruption to the operation of our facilities or our manufacturers’ operations. A safety issue or fire related to the cells could disrupt operations or cause manufacturing delays, and could lead to adverse publicity and, potentially, a safety recall, depending on the extent of any resultant damage or related injury.

##### Table of Contents

We are subject to many hazards and operational risks that can disrupt our business, including interruptions or disruptions in service at our facilities, for which we may not be able to secure adequate insurance policies, or secure insurance policies at reasonable prices.

Our operations are subject to many hazards and operational risks, including general business risks, product liability, and damages to third parties, the environment, our infrastructure or properties that may be caused by natural or manmade disasters, power losses, telecommunications failures, terrorist attacks (including hijacking, use of the aircraft as a weapon, or use of the aircraft to disperse a chemical or biological agent), security related incidents, human errors or certain EHS risks and hazards to our employees or third parties associated with our manufacturing operations. See also “—We could incur significant costs in complying with EHS laws and regulations and could be adversely affected by liabilities or obligations imposed under such laws and regulations.”.

We maintain general liability insurance, aircraft liability coverage, directors and officers (“D&O”) insurance and other insurance policies. There can be no assurance that our insurance will be sufficient to cover all potential claims or that present levels of coverage will be available in the future at reasonable cost or at all. Further, we expect our insurance needs and costs to increase as we grow and enhance production facilities and capabilities, manufacture aircraft and other aircraft parts and related products, establish commercial operations and expand into new markets. It is too early to determine what impact, if any, the commercialization of electric aircraft will have on our insurance costs, which may have an adverse impact on our business, results of operations, financial condition and prospects.

We may become subject to product liability claims, which could harm our business, reputation, results of operations, liquidity, financial condition and prospects if we are not able to successfully defend or insure against such claims.

We may become subject to product liability claims, which could harm our business, brand, results of operations, liquidity, financial condition and prospects. The aircraft industry experiences significant product liability claims and we face inherent risk of exposure to claims in the event our aircraft do not perform as expected or malfunction resulting in personal injury or death. A successful product liability claim against us could require us to pay a substantial monetary award. Moreover, a product liability claim could generate substantial negative publicity about our industry, aircraft and business and inhibit or prevent commercialization of other future aircraft candidates which would have material adverse aircraft on our business, brand, results of operations, liquidity, financial condition and prospects. We maintain product liability insurance for our aircraft and our products on a claims made basis, but we cannot assure that our insurance will be sufficient to cover all potential product liability claims. Any lawsuit seeking significant monetary damages either in excess of our coverage, or outside of our coverage, may have a material adverse effect on our business, brand, results of operations, liquidity, financial condition and prospects. We may not be able to secure additional product liability insurance coverage on commercially acceptable terms or at reasonable costs when needed, particularly if we do face liability for our products and are forced to make a claim under our policy.

We are highly dependent on the continued service and leadership of our founder, President and Chief Executive Officer and a member of our Board, Kyle Clark, and if we are unable to retain Mr. Clark, our ability to compete and overall performance could be harmed.

Our future success depends substantially on the continued contributions of our founder, Kyle Clark, whose vision, strategic direction and deep understanding of our technology, industry, target markets and mission have been integral to our innovation and growth outlook to date. Mr. Clark routinely engages directly with regulators and peers with first-hand experience and expertise not only as our CEO and Board member, but also as chair of the General Aviation Manufacturers Associate (GAMA) Electric Propulsion & Innovation Committee (EPIC). Mr. Clark is also a test pilot for our company. From engineering and product development to talent recruitment and long-term strategic planning, Mr. Clark plays a central role in virtually all aspects of our business, and while every member of our team is valuable, retaining the services and leadership of Mr. Clark is paramount.

39

##### Table of Contents

We maintain, and we expect to continue to maintain, a key person life insurance policy with respect to Mr. Clark. If Mr. Clark were to discontinue his current role in the future or should he be unable to fulfill his duties for some reason, this could significantly disrupt our operations, impede the execution of our business strategy or otherwise have a material adverse effect on our ability to compete in an increasingly complex, evolving market. Although we have assembled a strong, capable leadership team, there is no guarantee that we could replace Mr. Clark with someone of comparable expertise and vision.

Our future success depends on the continuing efforts of our key personnel and on our ability to attract and retain highly skilled personnel and senior management.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. In particular, we are highly dependent on the contributions of our senior management team and other key personnel. While our efforts to hire key personnel have generally been successful overall, the industry in which we operate is generally characterized by high levels of competition for skilled employees. Certain members of management, including our Chief Executive Officer, participate in various high-risk activities, such as recreational aviation, which carries the risk of serious injury and death. Relatedly, we support access to a flight program and use of aircraft by those of our personnel who elect to participate in our flight program. The loss of key personnel, including members of management as well as key engineering, product development, marketing and sales personnel, could disrupt our operations and make it more difficult to achieve our business plans.

Compensation packages for highly skilled personnel have increased over time and will likely continue to increase, and competition for highly skilled personnel is often intense, and we may incur significant costs to attract and retain our personnel. Although we have generally entered into employment offer letters with our key personnel, these letters have no specific duration and provide for at-will employment, which means our key personnel may terminate their employment relationship with us at any time. We may not be successful in attracting, integrating or retaining qualified personnel to fulfill our current or future needs. We have, from time to time, experienced, and we expect to continue to experience, difficulty or delay in hiring and retaining highly skilled personnel with appropriate qualifications. In addition, job candidates and existing personnel often consider the value of the equity awards they receive in connection with their service. If the perceived value of our equity or equity awards declines, it may adversely affect our ability to retain highly skilled personnel. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business, results of operations, financial condition and future growth prospects could be harmed.

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

Although none of our employees are currently represented by a labor union, unionized labor is common throughout the aerospace industry and can result in higher employee and benefit costs and increased risk of work stoppages, strikes and labor disputes. 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 harm our business, results of operations, financial condition and prospects.

We expect to conduct a portion of our business pursuant to U.S. government contracts, which are subject to unique risks.

We may enter into contracts with governmental organizations in the future. Sales to governmental organizations are subject to a number of challenges and risks that may adversely affect our business and operating results, including the following risks:

| • |  | new regulations, or changes to existing regulations, could result in increased compliance costs, and we could be subject to withheld payments and/or reduced future business if we fail to comply with new or existing requirements in the future;

| • |  | government demand and payment for our aircraft, motors, batteries and technologies may be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays

40

##### Table of Contents

| adversely affecting public sector demand for our offerings, including as a result of sudden, unforeseen and disruptive events such as government shutdowns, governmental defaults on indebtedness, competing priorities of a new administration, war, regional geopolitical conflicts around the world, incidents of terrorism, natural or manmade disasters and public health concerns including epidemics or pandemics;

| • |  | governments routinely investigate and audit government contractors’ administrative processes, and any unfavorable audit could result in the government refusing to continue buying our aircraft or other offerings, grants or other forms of government funding, which would adversely impact our revenue and operating results, or institute fines or civil or criminal liability if an investigation, audit or other review, were to uncover improper or illegal activities;

| • |  | contracts with governments are subject to additional requirements such as protective statutes (e.g., the civil False Claims Act), suspension and debarment as well as other legal actions and proceedings that generally do not apply to purely commercial contracts;

| • |  | governments may require certain products and technologies to be manufactured, developed, produced or offered solely in their country or in other relatively high-cost locations, and we may not manufacture, develop, produce or offer all products or technologies (or certain aspects thereof) in locations that meet these requirements, affecting our ability to sell these products or technologies to governmental agencies;

| • |  | refusal to grant certain certifications or clearance by one government agency, or a decision by one government agency that our products or technologies do not meet certain standards, may cause reputational harm and cause concern with other government agencies;

| • |  | certain types of contracts impact contractor profitability, intellectual property rights, and compliance requirements, increasing associated costs and risks; and

| • |  | heightened physical and cybersecurity requirements associated with information and access to manufacturing facilities and secure locations.

The occurrence of any of the foregoing could cause governmental organizations to delay or refrain from purchasing our aircraft or other offerings in the future or otherwise adversely affect our business and operating results.

The U.S. government may modify or terminate one or more of our existing or future contracts.

We have previously been awarded contracts with the DoD and may enter into additional contracts with other U.S. governmental organizations in the future. However, such opportunities carry the risk of the U.S. government’s ability to modify or terminate one or more of such contracts without prior notice and at the U.S. government’s convenience. We believe that the DoD may be shifting its priorities under the Agility Prime program towards hybrid aircraft and autonomous flight technology; however, any future contracts we secure with the U.S. government could be modified or terminated under standard U.S. government contract terms. Moreover, opportunities to pursue such contracts could be less than we currently anticipate. In addition, funding may be reduced or withheld as part of the annual U.S. Congressional appropriations process due to fiscal constraints, changing priorities, geopolitical or other reasons. Any loss or reduction of expected funding and/or modification or termination of one or more U.S. government contracts that may be awarded to us could have a material adverse effect on our access to government testing facilities and/or our ability to secure pre-certification operating experience and/or revenues, which could have an adverse impact on our business, results of operations, financial condition and prospects.

We may be unable to secure contracts or continue to grow our relationship with the U.S. government and the DoD.

We are currently pursuing contracts with the U.S. government that may enable us to supply our aircraft, charging capabilities and other products and technologies, and/or services related to them, to the DoD or other

41

##### Table of Contents

U.S. government agencies both prior to receiving a Type Certification from the FAA and after. While we believe we are uniquely qualified to participate in future initiatives, particularly those related to autonomous flight and hybrid aircraft, there can be no guarantees of our ability to negotiate and secure additional contracts in these areas. The timing of securing additional contracts may also be impacted by several factors that depend on actions by U.S. government personnel and the possibility remains that the time to secure additional contracts may be extended in the event of a bid protest. Our market is growing increasingly competitive and will continue to draw interest by large defense contractors as technology advances. Failure to obtain these contracts could limit our ability to gain additional operational learnings about our aircraft and other offerings and secure meaningful revenue, which could have a material adverse effect on business, results of operations, financial condition and prospects.

Our ability to attract and retain a U.S. DoD customer base and the related success of our defense program may be dependent upon our personnel obtaining and maintaining required security clearances for U.S. government classified work, as well as our ability to maintain our facility security clearance for the organization.

We maintain a Secret-level facility security clearance for the performance of classified DoD contracts and subcontracts. We operate under Security Control Agreement, which currently requires that the DoD approve one Director who is considered the Outside Director whose duties require that such director balance our business interests with U.S. national security interests in board-level decisions. In the future, one or more U.S. government contracts could require certain of our personnel to maintain various levels of security clearances in connection with our facility security clearance. The DoD has strict security clearance requirements for personnel who work on classified programs. Obtaining and maintaining security clearances for personnel involves a lengthy process, and it is difficult to identify, recruit and retain personnel who already hold security clearances. If our employees or other personnel are unable to obtain security clearances in a timely manner, or at all, or if our employees who hold security clearances are unable to maintain the clearances or terminate employment with us, then a potential or then-existing customer requiring classified work could elect not to award us a contract, terminate its contract with us or decide not to renew a contract upon its expiration, as applicable. In addition, we expect that many of the contracts on which we will bid will require us to demonstrate our ability to employ personnel with specified types of security clearances in addition to maintaining the organization’s facility security clearance. To the extent we are not able to engage personnel with the required security clearances for a particular contract, we may not be able to bid on or win defense or other government contracts, or effectively rebid on future contracts.

The National Industrial Security Program requires that a company maintaining a facility security clearance be effectively insulated from foreign ownership, control or influence (“FOCI”). We are party to a Security Control Agreement, dated June 15, 2025, by and among the DoD, QIA Industrials Holding LLC and BETA Technologies, Inc. (the “SCA”), as a suitable FOCI mitigation arrangement under the National Industrial Security Program Operating Manual Rule. Depending on changes to our ownership and governance composition, DCSA may determine, from time to time, that a different FOCI mitigation arrangement is appropriate.

We may be subject to risks associated with our strategic relationships.

We are or may be subject to risks associated with strategic relationships or other opportunities and may not be able to identify adequate strategic relationship opportunities, or form strategic relationships, in the future. We have entered into strategic relationships, and may in the future enter into additional strategic relationships or joint ventures or minority equity investments, in each case with various third parties for the production or operation of our aircraft as well as with other collaborators with capabilities on data and analytics and engineering.

We have also entered into agreements with potential partners in a number of international markets to establish operations in these markets. These alliances subject us to a number of risks, including risks associated with sharing proprietary information, non-performance by the third-party and increased expenses in establishing new strategic relationships, any of which may adversely affect our business. We may have limited ability to

42

##### Table of Contents

monitor or control the actions of these third parties and, to the extent any of these strategic third parties suffer negative publicity or harm to their reputation from events relating to their business, we may also suffer negative publicity or harm to our reputation by virtue of our association with any such third party.

Strategic business relationships will be an important factor in the growth and success of our business. However, there can be no assurances that we will be able to continue to identify or secure suitable business relationship opportunities in the future or our competitors may capitalize on such opportunities before we do. Moreover, identifying such opportunities could require substantial management time and resources, and negotiating and financing relationships involves significant costs and uncertainties. If we are unable to successfully source and execute on strategic relationship opportunities in the future, our overall growth could be impaired, and our business, prospects, financial condition and operating results could be adversely affected. Even if we are able to successfully source, negotiate and execute on strategic relationship opportunities, there can be no assurances that the expected synergies contemplated by the strategic business relationship will materialize, advance our business strategy, meet the expected return-on-investment targets or prove successful or effective for our business See also “—Our current collaboration with GE Aerospace and future strategic alliances could have an adverse effect on our financial condition and results of operations.”

When appropriate opportunities arise, we may acquire or license additional assets, products, technologies or businesses that are complementary to our existing business. In addition to possible stockholder approval, we may need approvals and licenses from relevant government authorities for the acquisitions or licenses and to comply with any applicable laws and regulations, which could result in increased delay and costs, and may disrupt our business strategy if we fail to do so. Furthermore, acquisitions or licenses and the subsequent integration of new assets and businesses into our own would likely require significant attention from our management and could result in a diversion of resources from our existing business, which in turn could have an adverse effect on our operations. Acquired or licensed assets or businesses may not generate the financial results we expect. Acquisitions or licenses could result in the use of substantial amounts of cash, potentially dilutive issuances of equity securities, the occurrence of significant goodwill impairment charges, amortization expenses for other intangible assets and exposure to potential unknown liabilities of the acquired business. Moreover, the costs of identifying and consummating acquisitions may be significant.

If conflicts arise between our collaborators or strategic partners and us, the other party may act in a manner adverse to us which could limit our ability to implement our strategies.

Our collaborators or strategic partners may develop, either alone or with others, products in related fields that are competitive with our products. Specifically, conflicts with key collaborators may adversely impact our ability to manufacture aircraft or scale production or sales. Conflicts with foreign partners may adversely impact our ability to scale operations outside the U.S. effectively. If such conflicts arise it may adversely affect our business, results of operations, financial condition and prospects.

We enter into aerospace commercial contracts, which are subject to unique risks, particularly with respect to contracts for our electric aircraft.

Contracts in the aerospace industry, and particularly aircraft contracts, may include complex technical terms governing the sale of our electric aircraft and/or maintenance, repair and overhaul support requirements. Pursuant to such contracts, we may provide services on an integrated basis, and may be required to provide warranty service and international support and/or meet certain service level, hardware performance and/or timing requirements, which may require us to assume additional risks associated with cost over-runs, delays and project losses.

Providing services on an integrated basis may also require us to assume additional risks associated with operating cost inflation, labor availability and productivity, supplier pricing and performance and potential claims for liquidated damages and other financial and contractual remedies for nonperformance. Circumstances

##### Table of Contents

out of our control, including disruptions in our supply chain, could delay our performance of such contracts. If the amount we are required to pay for these goods and services exceeds the amount we have estimated to be recognized as revenue, we could experience losses in the performance of these contracts. These delays and additional costs may be substantial, and we may be required to compensate customers for these delays, which may have an adverse impact on our business, results of operations, financial condition and prospects.

Our current collaboration with GE Aerospace and future strategic alliances could have an adverse effect on our financial condition and results of operations.

We may form strategic alliances or collaborations, such as our current collaboration with GE Aerospace, or create joint ventures with third parties that we believe will complement or augment our existing business. If we enter into strategic alliances or collaborations with promising technologies, we may not be able to realize the benefit of collaborating with such businesses if we are unable to successfully execute on the objectives of such strategic alliances or if exclusivity provisions prevent us from exploring alternative partnerships. In particular, our collaboration with GE Aerospace includes exclusive supply and right of first refusal (“ROFR”) provisions that may limit our ability to independently develop, source, or commercialize certain technologies, which could impact our flexibility and operational decision-making. We may encounter difficulties in developing, manufacturing and marketing any new technologies resulting from a strategic alliance or collaboration, including our current collaboration with GE Aerospace, that delay or prevent us from realizing their expected benefits or enhancing our business and may have an adverse effect on our results of operations. We cannot assure our stockholders that, following any such strategic alliance or collaboration, we will achieve the expected synergies to justify the transaction.

We may not realize all expected sales.

We cannot assure you that we will realize the revenue we expect to generate from our Backlog in the periods we expect to realize such revenue, or at all. Backlog represents the aggregate of our Firm Orders and Options. Agreements relating to our Backlog generally contain conditions with respect to the purchase of our aircraft or that require us to perform and provide certain deliverables ahead of completion of a purchase order. Certain of our contracts depend on certification of our aircraft by the FAA. Payment obligations arise after meeting certain manufacturing milestones. If the conditions to or performance of obligations under such agreements are not met, or if such agreements are otherwise canceled, modified or delayed, we may not generate the revenue we expect, which would materially and adversely affect our business, results of operations, financial condition and prospects. In addition, expected sales of our chargers, components and other offerings may not be realized.

A loss of one or more of our significant customers, their inability to perform under their contracts, or their default in payment, could negatively impact our revenues, results of operations and cash flows.

Historically, we have been dependent on a relatively small number of customers for our sales, and a small number of customers have accounted for a material portion of our revenue. For the year ended December 31, 2024, the U.S. government and United Therapeutics constituted 48% and 34% of total revenues, respectively. For the six months ended June 30, 2025, the U.S. government and United Therapeutics constituted 37% and 18% of total revenues, respectively. The loss of any one of our significant customers, their inability to perform under their contracts, or their default in payment, could have a materially adverse effect on our revenues, results of operations and cash flows.

We depend on suppliers and service partners for raw materials and certain parts and components.

Despite our high degree of vertical integration, we still rely on purchased materials and parts for our aircraft and all products and manufacturing equipment, which we source from suppliers globally, some of whom are currently single source suppliers, and certain of the components used in our aircraft that are custom made for us by third parties. To date, we have not qualified alternative sources for most of the single sourced components used in our aircraft and we generally do not maintain long-term agreements with our single source suppliers. For example,

44

##### Table of Contents

while several sources of the lithium-ion cell we have selected for battery packs are available, we have fully qualified only one supplier for these lithium-ion cells. While we believe that we may be able to establish alternate supply relationships and can obtain or engineer replacement components for our single source components, we may be unable to do so in the short term or at all at prices or costs that are favorable to us. In particular, while we believe that we will be able to secure alternate sources of supply for almost all of our single sourced components on a relatively short time frame, qualifying alternate suppliers or developing our own replacements for certain highly customized components of our electric aircraft, such as avionics, sidesticks or servos which are supplied to us by Garmin, Sensata Technologies and Volz Servos, respectively, may be time consuming and costly.

We face risks relating to the availability of these materials, parts and components, including that we will be subject to demand shortages and supply chain challenges and generally may not have sufficient purchasing power to eliminate the risk of price increases for the raw materials and lines we need. To the extent that we are unable to enter into commercial agreements with any of our suppliers on beneficial terms, or any of our suppliers experience difficulties ramping up their supply to meet our requirements, the production of our batteries and aircraft will be delayed and we will not be able to meet our production timelines.

Separately, we may be subject to various supply chain requirements regarding, among other things, conflict minerals, hazardous substance management, environmental sustainability and labor practices. We may be required to incur substantial costs to comply with these and potential future requirements, which may include locating new suppliers to replace existing ones, and could also be subject to substantial costs or penalties in the event of non-compliance. We may not be able to find any new suppliers for certain raw materials or components required for our operations, or such suppliers may be unwilling or unable to provide what we require. While we believe that we may be able to establish alternate supply relationships and can obtain substitutes, we may be unable to do so in the short-term, or at all, at prices that are favorable to us.

We expect to incur significant costs related to procuring various materials required to manufacture and assemble our batteries, aircraft and other products, which will require us to negotiate purchase agreements and delivery lead-times on advantageous terms. We may not be able to control fluctuation in the prices for these materials or negotiate agreements with suppliers on terms that are beneficial to us. Substantial increases in the prices for our raw materials, or our inability to reduce our raw material costs as we scale, would negatively impact our prospects.

In addition, currency fluctuations, geopolitics, trade barriers, embargoes, tariffs or shortages and other general economic or political conditions may limit our ability to obtain key materials or components for our batteries and aircraft or significantly increase freight charges, raw material costs and other expenses associated with our business.

While we have not experienced material supply chain disruptions to date, we may experience material supply chain disruptions in the future. Any disruption in the supply of materials, parts, services or outsourced components could temporarily disrupt research and development activities or production of our batteries or aircraft and could impede our commercialization efforts. Changes in business conditions, unforeseen circumstances, governmental and regulatory changes, and other factors beyond our control or which we do not presently anticipate could also affect our suppliers’ ability to deliver to us on a timely basis. Any of the foregoing could materially and adversely affect our business, results of operations, financial condition and prospects.

We may be unable to seek, obtain, maintain, protect or enforce our intellectual property rights, or to otherwise defend our intellectual property rights from unauthorized access or use by third parties.

Our success depends, in part, on our ability to seek, obtain, maintain, protect, defend or enforce our intellectual property rights, including technologies deployed in our current or future aircraft or utilized in our aircraft components and related products and services. To date, we have relied primarily on patents, trade secrets,

45

##### Table of Contents

trademarks, other intellectual property and contractual rights to protect our know-how, technology and proprietary information. Our software is also subject to certain protections under copyright law, though we have chosen to protect the software as a trade secret.

We routinely take steps to maintain, protect and enforce our intellectual property and proprietary technology. Although we seek to enter into agreements, including confidentiality, non-disclosure and intellectual property assignment agreements, with parties who have access to our intellectual property and proprietary technology, such as our employees, contractors, consultants, and other third parties, no assurance can be given that these agreements will be effective in controlling access to and distribution of our technology and proprietary information. In addition, such agreements may be breached, may not be self-executing or we may fail to enter into such agreements with all relevant individuals and entities. We may become subject to claims that current or former employees, contractors, consultants and other third parties engaged by us for development of intellectual property misappropriated intellectual property rights from their previous employers. Further, our employees are able to leave and may unintentionally take certain intellectual property with them to direct and indirect competitors. As such, we may also become subject to claims challenging the inventorship or ownership of our intellectual property, or claims that former employees, collaborators or other third parties have an ownership interest in our intellectual property. Accordingly, we cannot guarantee that the steps we have taken to protect our intellectual property will be adequate to prevent infringement of our rights or misappropriation of our technology, trade secrets or know-how that we have secured, or will be able to secure, appropriate permissions or protections for all of the intellectual property rights we use or claim rights to.

We also limit access to and restrict disclosure of our trade secrets and other proprietary or confidential information. For example, we rely on physical and electronic security measures to protect our proprietary information. However, we cannot provide assurance that these security measures will not be breached or will provide adequate protection for our proprietary or confidential information. We intend to continue to rely on the foregoing steps and other means in the future, but the steps we take to protect our intellectual property may be ineffective or inadequate to deter infringement, misappropriation, or other violations of our proprietary information or other intellectual property, and unauthorized parties may attempt to copy, reverse engineer or misappropriate aspects of our intellectual property or obtain and use information that we regard as proprietary. Additionally, it is possible that others will design around our intellectual property, independently develop the same, similar or superior technology or otherwise obtain access to our unpatented technology in a manner that does not violate our intellectual property rights, and in such cases we may have difficulty asserting trade secret rights against such parties or otherwise may not be able to successfully assert our intellectual property or other proprietary rights against them.

Costly and time-consuming litigation could be necessary to enforce and determine the scope of our intellectual property and related confidentiality and nondisclosure provisions. However, even if we initiate litigation against third parties such as suits alleging infringement, misappropriation, or other violations of our intellectual property, we may not prevail. Our efforts to enforce our intellectual property rights may be met with defenses, counterclaims, and countersuits attacking the validity and enforceability of our intellectual property rights. Moreover, third parties may challenge, invalidate, or circumvent our intellectual property and other proprietary rights, or otherwise assert rights therein or ownership thereof, including through administrative processes or litigation, and we may be unable to successfully resolve any such conflicts in our favor or to our satisfaction. Additionally, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. An adverse determination of any litigation proceedings could put our intellectual property at risk of being invalidated, unenforceable or interpreted narrowly and could put any of our related intellectual property at risk of not issuing or being cancelled. There could also be public announcements of the results of hearings, motions, or other interim proceedings or developments. Moreover, adequate remedies may not be available in the event of an unauthorized use or disclosure of our trade secrets. Trade secrets can be difficult to protect. While we strive to undertake measures that protect and preserve our trade secrets, such measures can be breached and would require extensive litigation to be compensated appropriately. In addition,

46

##### Table of Contents

our trade secrets may be independently discovered by competitors. Accordingly, if we fail to obtain or maintain our intellectual property, or if our competitors obtain our trade secrets or independently develop technology similar or superior to ours, our competitive market position could be materially adversely affected. Even if we obtain or maintain our intellectual property rights, we cannot guarantee that such rights will be valid, enforceable, sufficiently broad in scope or provide adequate protection of our intellectual property and any other proprietary rights.

Further, obtaining and maintaining patent, trademark, and copyright protection can be costly. We may choose not to, or may fail to, pursue or maintain such forms of protection for our technology in the United States or foreign jurisdictions, which could harm our ability to maintain our competitive advantage in such jurisdictions. It is also possible that we will fail to identify patentable aspects of our technology before it is too late to obtain patent protection, that we will be unable to devote the resources to file and prosecute all patent applications for such technology or that we will lose protection for failing to comply with all procedural, documentary, payment and other obligations during the patent prosecution process. Additionally, we do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims. Even if granted, there can be no assurance that the patent protections will not be narrowed or lost completely due to third party re-examination and other post-grant proceedings.

The laws of some countries do not protect proprietary rights to the same extent as the laws of the United States, and mechanisms for enforcement of intellectual property rights in some foreign countries may be inadequate to prevent other parties from infringing our proprietary technology. We may also fail to detect unauthorized access or use of our intellectual property, or to take appropriate steps to enforce our intellectual property rights, or we may be required to expend significant resources to monitor and protect our intellectual property rights, including engaging in litigation, which may be costly, time-consuming and divert the attention of management and resources, and may not ultimately be successful. If we fail to meaningfully establish, maintain, protect and enforce our intellectual property rights, our business, results of operations, financial condition and prospects could be adversely affected.

We have used certain of our intellectual property in performance of contracts with the U.S. government, and may do so more broadly in the future. The Federal Acquisition Regulation and Defense Federal Acquisition Regulation Supplement provide that the U.S. government may obtain certain rights in intellectual property, including patents, developed by us and our subcontractors and suppliers in performance of government contracts or with government funding. The U.S. government may use or authorize others (including our competitors) to use such patents and intellectual property for government and other purposes. The U.S. government is pursuing aggressive positions on the acquisition of broad data and software packages as well as the scope and applicability of these rights once acquired. The DoD is also implementing an overarching intellectual property acquisition policy that will require a greater focus and planning as to intellectual property rights for its programs, with the potential impacts of this policy or any associated regulatory changes on future acquisitions yet to be determined. The DoD’s efforts could affect our ability to protect and exploit our intellectual property. Governments may also challenge the sufficiency of intellectual property rights we have granted in government contracts and attempt to obtain greater rights, which could reduce our ability to protect our intellectual property rights and to compete. Relatedly, our ability to procure and perform government contracts requires us to obtain certain rights in the intellectual property of others through government grants. Governments may deny us the right to obtain such rights in the intellectual property of others, which may affect our ability to perform government contracts. Additionally, the U.S. government may choose to apply secrecy orders to various patent applications precluding their publication, foreign filing, and enforcement even if they become granted and issued patents.

Third parties may claim that we infringe, misappropriate or otherwise violate their intellectual property.

We have in the past been subject to, and could in the future be subject to, claims and legal proceedings regarding alleged infringement, misappropriation or other violation by us of the intellectual property rights of third parties. Such claims, whether or not meritorious, have in the past resulted in, and may in the future result in,

47

##### Table of Contents

the expenditure of significant time and financial, managerial, and engineering resources. To resolve these claims, we may enter into royalty-bearing and cross-licensing agreements, which may be only available on terms that are less favorable than currently available, or not at all, or we may be required to modify, redesign, undertake workarounds or substantial reengineering, stop selling or otherwise limit our ability to use or offer affected technologies, products, services, and branding materials, or pay damages, including damages to satisfy indemnification commitments with our customers. Even if a license is available to us, it could be non-exclusive, thereby giving our competitors and other third parties access to the same technologies licensed to us, which could adversely affect our business, financial condition and results of operations. Adverse outcomes could also include monetary damages, including legal fees, settlement payments and other costs or damages, or injunctive relief that may limit or prevent importing, marketing, and selling our products or services that have infringing, misappropriating or otherwise violating technologies. These risks have been amplified by the increase in third parties whose sole or primary businesses are to assert such claims.

Intellectual property rights do not necessarily address all potential threats.

The degree of future protection afforded by our intellectual property and other proprietary rights is uncertain

because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

| • |  | we might not have been the first to invent the inventions covered by our patent portfolio;

| • |  | we might not have been the first to file the patent application covering our patent portfolio or future patents;

| • |  | it is possible that any patent applications we may file in the future will not lead to issued patents;

| • |  | others may have access to intellectual property rights which have been licensed to us on a non-exclusive basis;

| • |  | our competitors might conduct R&D activities in countries where we do not have patent rights, or in countries where R&D safe harbor laws exist, and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;

| • |  | we may choose not to file a patent for certain inventions, instead choosing to rely on trade secret protection or know-how, and a third party may independently develop such invention and subsequently file a patent covering such invention; and

| • |  | the patents of third parties or pending or future applications of third parties, if issued, may have an adverse effect on our business.

Should any of these events occur, it could significantly harm our business, financial condition and results of operations.

Interruption to, interference with, or failure of our complex information technology and communications systems could hurt our ability to effectively operate our business.

We depend on our: (a) operational systems, including business, financial, accounting, product development, data processing or production processes, owned by us or our third-party vendors or suppliers; (b) facility security systems, owned by us or our third-party vendors or suppliers; (c) aircraft technology, including powertrain and avionics and flight control software, owned by us or our third-party vendors or suppliers; (d) integrated software in our aircraft and GSE; or (e) customer data that we process or our third-party vendors or suppliers process on our behalf. These systems could fail or be interrupted due to conditions beyond our control, including security incidents, cyber-attacks and agreement terminations with third-party service providers. A failure of or interruption to our systems could disrupt our business operations, result in loss of intellectual property, trade secrets or other proprietary or competitively sensitive information, compromise certain 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 aircraft and GSE.

48

##### Table of Contents

We collect, store, transmit and otherwise process data from our aircraft and GSE, our employees and others as part of our business and operations, which may include personal, confidential or proprietary information. We also work with partners and third-party service providers or vendors that collect, store and otherwise process such data on our behalf and in connection with our aircraft and GSE.

We plan to use data connectivity software to monitor aircraft performance, enhance safety and enable cost-saving preventative maintenance. Our services depend on the availability, effectiveness and continued operation of information technology and communications systems and our ability to obtain and maintain satisfactory contracts with service providers. Our systems, or those of our third-party service providers, may be vulnerable to damage or interruption from physical theft, fire, terrorist attacks, natural or manmade disasters, power loss, actual or threatened acts of war, telecommunications failures, insider theft or misuse, human error and similar events. We and our third-party service providers are also vulnerable to cybersecurity-related incidents, including, among others, computer viruses, worms, trojan horses, bugs, distributed denial or degradation of service attacks, ransomware, malware, infiltration by unauthorized persons, malicious and destructive code, phishing attacks, social engineering schemes, or other attempts to harm our systems or those of our third-party service providers. We intend to log information about each aircraft’s use to aid in aircraft diagnostics and servicing. Our customers may object to the use of this data or place limitations that materially restrict its use, which may increase our aircraft maintenance costs and harm our business prospects.

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, sales and service processes. These risks may affect our ability to manage our data and inventory, to procure parts or supplies, to manufacture, deploy, deliver and service our aircraft and GSE, to adequately protect our intellectual property, or to achieve and maintain compliance with, or to realize available benefits under, applicable laws, regulations and contracts. We cannot be sure that these systems, including those of our third-party vendors or suppliers, will be effectively implemented, maintained or expanded as planned. If we do not successfully implement, maintain or expand these systems as planned, our operations may be disrupted and our ability to accurately and timely report our financial results could be impaired. Moreover, our proprietary information or intellectual property could be compromised or misappropriated, which could adversely affect our reputation. We may need to expend significant resources to make corrections or find alternative sources for these functions if such functions do not operate as intended.

We, along with our third-party service providers, vendors and suppliers, are at risk for cybersecurity-related attacks and cyber-incidents, which may adversely affect our business.

Cybersecurity risks and cyber-incidents may adversely affect our business by disrupting our operations or those of our third-party service providers, vendors and suppliers, compromising or corrupting our confidential information and/or damaging our business relationships, all of which could negatively impact our business, reputation, results of operations, financial condition and prospects. Although we have implemented a variety of security measures, our computer systems, networks and data, like those of other companies, could be subject to cyber-incidents, including intentional attacks or unauthorized access, use, alteration or destruction. Third parties, including activist, criminal, nation-state or terrorist actors, may attempt to fraudulently induce us or our personnel to disclose sensitive information (including passwords) in order to gain access to data, accounts, funds or other assets, or otherwise to inflict harm. In the event that we are subject to a successful cyber-attack or other cyber-incident, substantial losses may occur in the form of stolen, lost or corrupted: (i) data or payment information; (ii) financial information; (iii) software, contact lists or other databases; (iv) proprietary information or trade secrets; or (v) other items.

As our reliance on technology has increased, including internet or cloud-based programs, so have the risks posed to our internal and third-party information systems. Our aircraft contain complex information technology systems and built-in data connectivity to share aircraft data with ground operations infrastructure. We design, implement and test security measures intended to prevent unauthorized access to our information technology

49

##### Table of Contents

networks, our aircraft and related systems but these measures do not guarantee that a cyber-attack or cyber-incident will not occur. Hackers may attempt to gain unauthorized access to modify, alter, or use such networks, aircraft and systems to gain control of or to change our aircraft’s functionality or performance characteristics, or to gain access to data stored in or generated by the aircraft. A significant breach of our third-party service providers’ or vendors’ or our own network security and systems could have serious negative consequences for our business and future prospects, including possible fines, penalties and damages, reduced customer demand for our aircraft and harm to our reputation and brand.

Cybersecurity threats are constantly evolving and are difficult to predict due to advances in the technological capabilities and methods of threat actors, including phishing, social engineering or other illicit acts. We cannot be sure that any security measures that we or our third-party service providers or vendors have implemented will be effective against current or future security threats. For example, we may have limited insight into the data privacy or cybersecurity practices of third-party service providers and vendors. Even if our own security measures remain intact, cyber-attacks, data breaches, security incidents, malicious internet-based activities or other incidents or failures at one of our third-party service providers or our vendors could compromise our systems and data. Further, in such a circumstance, we may not receive timely notice of, or sufficient information about, the breach or other incident or failure, or be able to exert any meaningful control of or influence over how and when the breach or other incident or failure is addressed. Any theft, loss, or misappropriation of, or access to, clients’ or other proprietary data, or other breach of our third-party service providers’ and vendors’ information technology systems, could disrupt our operations, damage our reputation, result in fines, legal claims, or proceedings, including regulatory investigations and actions, liability for failure to comply with privacy and information security laws, or otherwise result in loss of revenue, fraudulent transactions, loss of clients, transaction errors, processing inefficiencies, service reliability and increased costs, including costs to deploy additional personnel and protection technologies, train employees and engage third-party experts and consultants. Further, the costs of mitigating cybersecurity risks may be significant, including, but not limited to, retaining the services of cybersecurity providers; compliance costs arising out of existing and future cybersecurity, data protection and privacy laws and regulations; and costs related to maintaining redundant networks, data backups and other damage-mitigation measures. Moreover, the mere perception of a security breach involving us or any part of the broader aerospace industry, whether or not true, could also damage our business, operations or reputation.

Threat actors, nation-states and nation-state supported actors now engage, and are expected to continue to engage, in cyber-attacks, including for geopolitical reasons and in connection with military conflicts and operations. During times of war and other major conflicts, we and our third-party vendors or suppliers may be vulnerable to heightened risk of these attacks. Our systems, networks and physical facilities could be breached, or personal information could otherwise be compromised due to employee error or malfeasance, if, for example, third parties attempt to fraudulently induce our employees or our customers to disclose information or usernames and/or passwords. Third parties may also exploit vulnerabilities in, or obtain unauthorized access to, platforms, systems, networks and/or physical facilities utilized by our third-party service providers and vendors. If a compromise of data were to occur, we may become liable under our contracts with other parties and under applicable law for damages, incur penalties and be responsible for other costs to respond to such an incident.

In addition, we are subject to domestic and international cybersecurity-related laws and regulations, alongside government, customer and other cybersecurity requirements. The scope and breadth of these requirements have expanded our compliance obligations, and cybersecurity regulatory enforcement activity has grown. We expect regulatory and compliance requirements to continue to evolve. Staying apace with these regulatory changes could require us, our suppliers and our business partners to modify existing practices, increase operational and compliance expenditures and incur new or additional information technology and product development expenses. Given that compliance with regulatory changes can take time, it is possible that our practices may not at all times comply fully or partially with all applicable requirements. Additionally, a failure to comply with the National Institute of Standards and Technology Special Publication 800-171, 32 CFR Part 117 or other applicable U.S. government or DoD cybersecurity requirements and guidelines, including the

50

##### Table of Contents

Cybersecurity Material Model Certificate (“CMMC”), whether or not resulting in a security breach or disruption, could restrict our ability to bid for, be awarded and perform on DoD contracts. DoD requirements to comply with the CMMC and its obligations now and in the future may cause additional expense. We plan to implement cybersecurity policies and frameworks based on industry and governmental standards to align closely with DoD requirements, instructions and guidance. Moreover, we continue to work with the DoD on assessing cybersecurity risk and on policies and practices aimed at mitigating these risks.

We may be subject to increased compliance burdens by certain regulators and customers with respect to our aircraft and products, as well as additional costs to oversee and monitor security risks. Most jurisdictions have enacted laws mandating companies to inform individuals, stockholders, regulatory authorities and/or others of security breaches. In addition, some of our customer agreements may require us to promptly report security breaches on our systems. These mandatory disclosures can be costly, harm our reputation, erode customer trust and require significant resources to mitigate issues stemming from actual or perceived security breaches.

While we currently maintain cyber liability insurance, our insurance may be insufficient or may not cover all liabilities we could incur. A successful claim against us that exceeds our available cyber liability insurance coverage or results in changes to our insurance policies (including premium increases or the imposition of large deductible or co-insurance requirements) could adversely affect our business. In addition, we cannot be sure that our existing cyber liability insurance coverage will continue to be available on acceptable terms or that our insurers will not deny coverage as to any future claim.

We are subject to evolving Privacy Laws, which subjects us to a number of potential regulatory and reputational risks. We may face investigations, fines and sanctions as a result of our or our service providers’ actual or perceived failure to comply with the Privacy Laws and incur increased operational costs in order to ensure future compliance.

We currently do, and in the future expect to continue to, collect, store, transmit and otherwise process data from our aircraft and GSE, our customers, our employees and others as part of our business and operations, which may include personal, confidential or proprietary information. We also work with partners and third-party service providers or vendors that collect, store and process such data on our behalf and in connection with our aircraft and GSE. As such, we are subject to data protection, privacy, cybersecurity and/or information security laws, regulations, and industry standards in the jurisdictions in which we do business (collectively, the “Privacy Laws”). These Privacy Laws impose obligations in relation to the collection, use, and disclosure of personal information, including providing consumers with certain rights to access, correct, delete, and restrict the processing of their personal information.

The Privacy Laws are constantly evolving and can be subject to significant change. As a result, the application, interpretation, and enforcement of the Privacy Laws and regulations are often uncertain, particularly in the new and rapidly evolving industries in which we operate. These laws and regulations may be interpreted and applied inconsistently from jurisdiction to jurisdiction and inconsistently with our current policies and practices. For example, regulatory or legislative actions or litigation could adversely affect the manner in which we provide our products and services, or adversely affect our financial results, including by imposing significant fines that increasingly may be calculated based on global revenue. Compliance with applicable Privacy Laws may require adhering to stringent legal and operational obligations and necessitate dedicating substantial time and financial resources, which may increase over time.

Numerous jurisdictions, including other states in the United States, have either passed, proposed, adopted or are considering laws and regulations related to the collection, use or other processing of data. Given the rapidly evolving landscape of data privacy and security laws, we cannot yet determine the full impact these privacy, security, and data protection laws and regulations, or other such future privacy, security, and data protection laws and regulations, may have on our current or future business. Such laws and regulations are expected to vary from jurisdiction to jurisdiction, thus increasing costs, operational and legal burdens, and the potential for significant

liability for regulated entities. Additionally, these laws and regulations, and any changes or new laws or

51

##### Table of Contents

regulations, could impose significant limitations, require changes to our business, or restrict our use or storage of personal information, which may increase our compliance expenses and make our business more costly or less efficient to conduct. In addition, any such changes could compromise our ability to develop an adequate marketing strategy and pursue our growth strategy effectively, which, in turn, could adversely affect our business, results of operations, financial condition and prospects. Finally, any actual or perceived failure to comply with these laws could result in a costly investigation, enforcement actions, fines or litigation resulting in potentially significant liability or other costs and a material and adverse impact on our reputation and business.

Our use of artificial intelligence (“AI”) technologies may adversely impact our business, reputation, financial condition and results of operations.

We use AI technologies in connection with our business operations and intend to increase this use over time. Our use of AI technologies, particularly generative AI technologies, carries certain risks, including regarding the accuracy and quality of AI outputs, which may or may be perceived to be inaccurate, incomplete, biased, misleading, discriminatory or otherwise inappropriate for our needs, which could adversely affect our business and reputation. Our use of AI, particularly generative AI, may also create legal and financial exposure, including for claims and liabilities associated with AI outputs that may be alleged to infringe the intellectual property rights of third parties.

Furthermore, our use or any use by our contractors, consultants, vendors or service providers, of third-party AI providers to process our confidential or other sensitive information could put the confidentiality of such information at risk, including if any such third-party AI provider breaches its contractual obligations to us, suffers cyber-attacks or intentionally or inadvertently discloses, or misuses our confidential or sensitive information or otherwise incorporates the same into publicly available training sets. In such an instance, it is possible that our confidential or other sensitive information could become available to third parties, including our competitors. We or our employees may use AI technologies, inadvertently or otherwise, in a manner that puts our confidential information or intellectual property rights at risk. Any of the foregoing risks may result in diversion of management’s attention and resources, and may harm our business, reputation, results of operations, financial condition and prospects.

Further, any output created by us using AI technologies may not be subject to copyright protection, which may adversely affect our intellectual property rights in, or ability to commercialize or use, any such content. In the United States, a number of civil lawsuits have been initiated related to the foregoing and other concerns, any one of which may, among other things, require us to limit the ways in which we use AI technologies. To the extent that we do not have sufficient rights to use the data or other material or content used in or produced by the AI technologies we employ, or if we experience cybersecurity incidents in connection with our use of AI, it could adversely affect our reputation and expose us to legal liability or regulatory risk, including with respect to third-party intellectual property, privacy, data protection and cybersecurity, publicity, contractual or other rights. Further, our competitors or other third parties may incorporate AI into their products more quickly or more successfully than us, which could impair our ability to compete effectively.

Additionally, changes in AI technology could require us to make significant ongoing investments to maintain and upgrade our technological capabilities. We may not successfully implement these developments in a timely or cost-effective manner, or at all, and the AI technologies in which we invest may be less effective than expected, or become unavailable to us on favorable terms, or at all. We may also be impacted by risks related to evolving laws, regulations and standards regarding the development and use of AI technologies. Changes in laws, regulations or industry standards governing AI use could lead to increased costs and compliance requirement or restrict our ability to use certain AI technologies in our operations altogether.

As the use of AI becomes more prevalent, we anticipate that it will continue to present new or unanticipated ethical, reputational, technical, operational, legal, competitive and regulatory issues, among others. We expect that our incorporation of AI in our business will require additional resources, including the incurrence of additional costs, to develop and maintain our products and features to minimize potentially harmful or

52

##### Table of Contents

unintended consequences, to comply with applicable and emerging laws and regulations, to maintain or extend our competitive position, and to address any ethical, reputational, technical, operational, legal, competitive or regulatory issues which may arise as a result of any of the foregoing.

Social media and mobile messaging platforms present risks and challenges to maintaining and enhancing our brand, and any damage to our reputation or information leakage could adversely impact our business.

The inappropriate and/or unauthorized use of certain social media and mobile messaging channels could cause brand damage or information leakage or could lead to legal implications, including from the improper collection and/or dissemination of personally identifiable information. In addition, negative or inaccurate posts or comments about our company, technologies or products on any social networking platforms could damage our reputation, brand image and goodwill. Further, the disclosure of non-public Company-sensitive information by our current or former personnel or others through external media channels could lead to information loss. Although we have internal communications, social media and mobile messaging protocols that guide our employees on appropriate personal and professional use of these platforms for communication about the Company, the processes in place may not completely secure and protect information. Identifying potential new points of unauthorized entry as new communication tools expand also presents new challenges.

Moreover, repairing our brand and reputation in the case of any adverse event may be difficult, time-consuming and expensive. Our failure to address, or the appearance of our failure to address, issues that give rise to reputational risk could significantly harm our brand and reputation. To the extent we fail to respond quickly and effectively to address corporate crises and other threats to our brand and reputation, the ensuing negative public reaction could significantly harm our brand and reputation, which could result in loss of trust from our consumers, third-party service providers and employees and could lead to an increase in litigation claims and asserted damages or subject us to regulatory actions or restrictions.

We are subject to risks associated with global climate change, including physical and transitional risks.

The potential physical effects of climate change, such as increased frequency and severity of high wind conditions, storms, floods, fires, fog, mist, freezing conditions, droughts, sea-level rise and other climate-related events, could affect our operations, assets, infrastructure, supply chain and financial results. Climate change risks could result in but are not limited to operational risk from the physical effect of climate events on our charging facilities, production facilities and other assets and we could incur significant costs to improve the climate resiliency of our aircraft or infrastructure and otherwise prepare for, respond to, and mitigate such physical effects of climate change. We may also be impacted by transitional risks related to climate change, including new or more stringent regulatory requirements, increased monitoring and disclosure requirements and potential effects on our reputation and/or changes in our business. Changes in climate change laws or regulations could lead to increased costs and compliance requirements or otherwise could negatively impact our business and/or competitive position. Further, there is an increased focus from a variety of stakeholders, including governments, investors, lenders and customers, on climate change matters, including increased pressure and regulatory requirements to expand disclosures related to the physical and transition risks related to climate change or to establish climate-related goals, such as the reduction of greenhouse gas emissions, which could expose us to market, operational and execution costs or risks. Our failure to comply with applicable requirements or establish such climate-related targets or targets that are perceived to be appropriate, as well as to achieve progress on those targets on a timely basis, or at all, could adversely affect the reputation of our brand and business and demand for our offerings. We are not able to accurately predict the materiality of any potential losses or costs associated with the physical effects of climate change.

Our aircraft utilization may be lower than expected due to weather and other factors.

Although we design our aircraft to maximize operational utilization, our aircraft may not be able to fly in poor weather conditions, including snowstorms, thunderstorms, high winds, lightning, hail, known icing

53

##### Table of Contents

conditions and/or fog. Our inability to operate in these conditions will reduce our aircraft utilization and cause delays and disruptions. We intend to maintain a high daily aircraft utilization rate, which is the amount of time our aircraft spend in the air. This is achieved, in part, by reducing turnaround times at vertiports. Aircraft utilization is reduced by delays and cancellations from various factors, many of which are beyond our control, including adverse weather conditions, security requirements, air traffic congestion and unscheduled maintenance events. The success of our business is dependent, in part, on the utilization rate of our aircraft, and reductions in utilization would adversely impact our financial performance, cause customer dissatisfaction and could have an adverse impact on our business, results of operations, financial condition and prospects.

Our aircraft and chargers may require maintenance at frequencies or at costs which are unexpected.

Our aircraft and network of chargers will require regular maintenance and support. We are still developing our understanding of the long-term maintenance profile of these and certain of our other offerings. If useful lifetimes are shorter than expected, or if trained and qualified aircraft mechanics continue to be in short supply, this may lead to greater maintenance costs than we anticipate. If our aircraft and related equipment or our chargers require maintenance more frequently than anticipated or at costs that exceed our estimates, that could impact our commercialization efforts or, in the case of our charging network, could result in higher operating costs, or otherwise negatively impact customer satisfaction or demand with respect to our offerings. Any of these could have a material adverse effect on our business, results of operations, financial condition or prospects.

If we are unable to maintain adequate facilities and infrastructure, including securing access to key infrastructure, we may be unable to offer our aircraft and other products or charging services in a way that is useful to customers.

If we are unable to obtain and maintain adequate facilities and infrastructure, including access, on commercially viable terms, to key infrastructure such as airports where our chargers are then-located or proposed to be located, we may be unable to offer our aircraft and other products or charging services in a way that is useful to passengers. To operate and expand our current and planned business activities, we must secure or otherwise develop adequate manufacturing, testing, charging and maintenance infrastructure in fit-for-purpose and, in the case of our charging network, desirable locations.

There is also a complex patchwork of federal, regional and municipal regulatory considerations applicable to asset management and property development in general, and aviation assets and infrastructure in particular, including EHS regulations. See also “—We could incur significant costs in complying with EHS laws and regulations and could be adversely affected by liabilities or obligations imposed under such laws and regulations.” The nature and extent of any changes in these laws, rules, regulations and permits associated with these laws and regulations may be unpredictable and may have material effects on our business. Local community groups, some of which may be opposed to property development in general, and new aviation infrastructure in particular, can impact the application of these regulations or the development of new regulations.

Our facilities are subject to a risk of closure due to zoning, permitting and leasing issues. We may not be able to obtain necessary permits and approvals or to make necessary infrastructure changes to enable adoption of our aircraft, charging equipment or other offerings. Further, the destruction of or our inability to use any of our facilities for a prolonged period of time could materially impact our ability to meet our projected timelines. If we are unable to acquire, lease or otherwise maintain space and related facilities integral to our operations on terms and in locations that are favorable, this could prevent our aircraft and other offerings from being purchased or deemed desirable by our customers and, in turn, have a material adverse effect on our business, results of operations, financial condition and prospects.

Our ability to use net operating losses and other tax attributes to offset future taxable income may be subject to certain limitations.

As of December 31, 2024, we had federal and state net operating losses (“NOLs”) of approximately $364.7 million and $289.3 million, respectively, and as of June 30, 2025, we had federal and state NOLs of approximately $484.7 million and $345.1 million, respectively, which carryforward indefinitely for federal purposes and begin to expire for state purposes in 2030. We intend to file amended state and local tax returns for years 2021 and 2022 due to a recent analysis of state apportionment and have recorded the anticipated effects of the amended returns as of June 30, 2025. As of December 31, 2024, we had federal and state research and development tax credit carryforwards of approximately $19.0 million and $2.9 million net of federal benefit, respectively, and as of June 30, 2025, we had federal and state research and development tax credit carryforwards of approximately $21.2 million and $4.2 million, respectively, which begin to expire for federal and state purposes in 2039. Under the Tax Cuts and Jobs Act of 2017 (“TCJA”), federal NOLs generated in tax years through December 31, 2017 may be carried forward for 20 years and may fully offset taxable income in the year utilized and federal NOLs generated in tax years beginning after December 31, 2017 may be carried forward indefinitely but may only be used to offset 80% of taxable income annually. Further, under the TCJA, federal and state research and development tax credits may be carried forward for 20 years. Our U.S. federal and state NOLs and certain other tax credits (such as research and development tax credits) may be subject to limitation under Sections 382 and 383 of the Code, respectively, and similar provisions of state law. Under those sections of the Code, a corporation that undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, is subject to limitations on its ability to utilize its pre-change NOLs and other pre-change tax attributes, such as research and development tax credits, to offset post-ownership change taxable income or taxes. If we undergo an ownership change in connection with or after this offering, our ability to utilize NOLs and other tax attributes could be further limited by Sections 382 and 383 of the Code. In addition, future changes in our stock ownership, many of which are outside of our control, could result in an ownership change under Sections 382 and 383 of the Code. “Ownership changes” that have occurred in the past or that may occur in the future could result in the imposition of an annual limit on the amount of pre-ownership change NOLs and other tax attributes we can use to reduce taxable income, potentially increasing and accelerating our liability for income taxes.

Changes in financial accounting standards may cause adverse unexpected fluctuations and affect our reported results of operations.

A change in accounting standards or policies, and varying interpretations of existing or new accounting pronouncements, as well as significant costs incurred or that may be incurred to adopt and to comply with these new pronouncements, could have a significant effect on our reported financial results or the way we conduct our business. If we do not ensure that our systems and processes are aligned with the new standards, we could encounter difficulties generating quarterly and annual financial statements in a timely manner, which could have an adverse effect on our business, our ability to meet our reporting obligations and compliance with internal control requirements.

Management will continue to make judgments and assumptions based on our interpretation of new standards. If our circumstances change or if actual circumstances differ from our assumptions, our operating results may be adversely affected and could fall below our publicly announced guidance or the expectations of securities analysts and investors, resulting in a decline in the market price of the Class A common stock.

Increasing scrutiny, regulatory requirements and changing expectations from various stakeholders with respect to sustainability and other environmental, social and governance matters may impose additional costs on us or expose us to reputational or other risks.

Investors, customers and other stakeholders have focused increasingly on sustainability and environmental, social and governance practices of companies, including, among other things, practices with respect to human capital resources, emissions, climate change and environmental impact. Stakeholder expectations are not uniform

55

##### Table of Contents

and support for and opposition to such matters have increasingly resulted in a range of activism and legal and regulatory developments. Expectations and requirements of our investors, customers and other third parties evolve rapidly, whether in support of or opposition to such matters, and are largely out of our control, and our initiatives and disclosures in response to such expectations and requirements may result in increased costs (including but not limited to increased costs related to compliance, stakeholder engagement, contracting and insurance), changes in demand for certain services, enhanced compliance or disclosure obligations or other adverse impacts to our business, financial condition and results of operations. While we have programs and initiatives in place related to our sustainability practices, there is no assurance that our stakeholders will agree with our sustainability-related strategies, and investors may decide to reallocate capital or to not commit capital as a result of their assessment of our services and practices. In addition, our customers, business partners and suppliers may be subject to similar expectations and may require that we implement certain additional procedures or standards to continue to do business with us, which may augment or create additional costs or risks, including costs or risks that may not be known to us. Relatedly, there is increasing focus by regulators, customers and other stakeholders on greenwashing issues and environmental marketing and sustainability-related claims. There can be no assurance that we will not be subject to greenwashing allegations or claims associated with the veracity of our environmental- and sustainability-related claims, including those related to the environmental sustainability and energy efficiency of our aircraft, our renewable energy usage or our battery recycling practices, among other things, which could expose us to liabilities or require us to incur additional costs to adequately prepare disclosures or improve internal controls. There is also increasing focus on environmental, social and governance and sustainability disclosure and regulation across various jurisdictions and exposure to any new regulatory and legal requirements may lead to increased operational costs and compliance burden for us. Any failure to comply with regulatory or legal requirements or adapt to investor, customer and other stakeholder expectations and standards, which are evolving and can conflict, or if we are perceived (whether validly or not) not to have responded effectively to their growing concerns around sustainability or environmental, social and governance issues, regardless of whether there is a legal requirement to do so, or to effectively respond to new or additional legal or regulatory requirements regarding such matters or potential regulatory/investor engagement or litigation, could cause or result in reputational harm to our business and could have a material adverse impact on our business, financial condition and results of operations.

We may in the future become subject to legal proceedings, which may be time-consuming and expensive and, if adversely determined, could delay, limit or prevent our ability to commercialize our aircraft or otherwise execute on our business plans.

Future legal proceedings against us or our employees, regardless of outcome or merit, could be time consuming and expensive to defend or resolve, result in substantial diversion of management and technical resources, delay, limit or prevent our ability to make, develop, commercialize or deploy our aircraft and deteriorate our reputation and our business relationships, any of which could make it more difficult or impossible for us to operate our business or otherwise execute on our business plan and significantly adversely affect our business, results of operations, financial condition or prospects. In the event of an adverse outcome of litigation, we may have to cease developing and/or using the asserted intellectual property, which could significantly adversely impact our business, results of operations, financial condition or prospects.

The requirements of being a public company will cause us to incur increased costs and may strain other resources, divert management’s attention and affect our ability to attract and retain additional executive management and qualified board members.

We will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the listing requirements of the NYSE and other applicable securities rules and regulations. Compliance with these rules and regulations will increase, and may continue to increase, our legal and financial compliance costs, make some activities more difficult, time-consuming, or costly, and increase demand on our systems and resources. The Exchange Act requires, among other things, that, once we are a public company, we file annual, quarterly and

56

##### Table of Contents

current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that, once we are a public company, we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight will be and may in the future be required. As a result, management’s attention may be diverted from other business concerns, which could adversely affect our business and operating results. Although we will hire additional employees to comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which would increase our costs and expenses.

In the future, changes in laws or regulations governing our operations, changes in the interpretation thereof or newly enacted laws or regulations and any failure by us to comply with these laws or regulations, could have a materially adverse effect on our business. In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure could create uncertainty for public companies, increase legal and financial compliance costs, and make some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve or otherwise change over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards (or changing interpretations of them), and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us, and our business may be adversely affected. As a public company, we will also have to incur increased expenses in order to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to maintain the same or similar coverage or obtain coverage in the future. These factors could also make it more difficult for us to attract and retain qualified members of our Board, particularly to serve on our audit committee, compensation committee and nominating and governance committee, and qualified executive officers.

As a result of disclosure of information in the filings required of a public company, our business and financial condition will be more visible, which may result in threatened or actual litigation, including by competitors. If such claims are successful, our business and operating results could be adversely affected, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and adversely affect our business and operating results. In addition, as a result of the disclosure obligations as a public company, we may have reduced flexibility and be under pressure to focus on short-term results, which may adversely affect our ability to achieve long-term profitability.

Our management team has limited experience managing a public company.

Some members of our management team have limited experience managing a publicly traded company, interacting with public company investors and regulators and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could adversely impact our business, results of operations, financial condition and prospects.

Risks Related to Laws and Regulations

Failure to comply with applicable laws and regulations relating to the aerospace business in general and electric aircraft testing, certification and production specifically, could adversely affect our business, results of operations, financial condition and prospects.

In order to commercialize our product offerings, we will need to obtain and maintain approvals from governmental authorities based on compliance with a variety of aerospace laws and regulations. If we are unable to obtain, experience delays in obtaining, or are unable to maintain such approvals, our business could be negatively impacted. Our electric aircraft, motors and subsystems will be subject to substantial regulation in the jurisdictions in which we intend our electric aircraft and other offerings to be sold and used. We expect to incur significant costs in complying with these regulations. Regulations related to eVTOL aircraft in particular, including aircraft certification, Production Certification, passenger operation, flight operation, including operations under experimental and special airworthiness certificates, airspace operation, security regulation and infrastructure regulation are currently evolving, and we face risks associated with the development, evolution and enforcement of these regulations. For example, in October 2024, the FAA published the SFAR for eVTOL aircraft. Any other regulatory changes or revisions could delay our ability to obtain Type Certification, and could delay our ability to execute on our business plans with respect to sale of aircraft and certain other offerings.

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 aircraft would have a material adverse effect on our business and operating results. In addition to obtaining and maintaining certification of our aircraft, we will need to obtain and maintain a production certificate necessary to manufacture type certified aircraft and motors. A transportation or aviation authority may determine that we cannot manufacture, provide, or otherwise engage in those product or service offerings as we have contemplated. The inability to commercialize our envisioned product offerings could materially and adversely affect our business, results of operations, financial condition and prospects.

To the extent the laws change, our aircraft and/or related or other offerings may not comply with those laws, which would have an adverse effect on our business. Complying with changing laws could be burdensome, time consuming and expensive. To the extent compliance with new laws is cost prohibitive, our business, results of operations, financial condition and prospects could be adversely affected.

Our aircraft must be certified with the FAA in the United States or other comparable regulatory agencies in international jurisdictions. If we expand beyond the United States, there will be additional 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. See “—We may be unable to obtain relevant regulatory approvals for the commercialization of our aircraft, motors or subsystems, either in the United States or in foreign markets.”

Continued regulatory limitations and other obstacles interfering with our business operations could have a negative and material impact on our business, results of operations, financial condition and prospects.

We are required to comply with a wide variety of laws and regulations, and are subject to regulation by various federal, state and foreign agencies, and our failure to comply with existing and future regulatory requirements could adversely affect our business, results of operations, financial condition and prospects.

We expect to compete in markets in which we and our customers are subject to federal, state, local, international and transnational laws and regulations, including, but not limited to, laws and regulations relating to zoning and those imposing requirements with respect to business licenses and registrations. Any significant change in laws, regulations and standards could impact the manner in which we conduct business, as well as the

58

##### Table of Contents

design, manufacture and operation of our electric aircraft and other offerings, delay our timeline or reduce demand for our products or increase our expenses. For example, business licenses and the approval to operate can vary by country, state and municipality.

We are also registered with the Directorate of Defense Trade Controls of the U.S. Department of State, as is required to manufacture and export goods controlled by the ITAR, and we are subject to strict export control and prior approval requirements related to these goods. Our failure to comply with the ITAR and other export control laws and regulations, as well as economic sanctions, could result in penalties, loss, or suspension of contracts or other consequences. Any of these could adversely affect our business, results of operations, financial condition and prospects. Failure by us or by our customers to meet one or more of these various regulatory obligations could have adverse consequences in the event of material non-compliance. Compliance with relevant sanctions and export control laws could restrict our access to, and increase the cost of obtaining, certain products and at times could interrupt our supply of imported inventory or our ability to service certain customers. Conversely, compliance with these regulatory obligations may require us to incur significant expenses.

In addition, certain of our facilities and products are or will be certified to industry standards such as ISO, AS9100 and/or UL. These standards are voluntary safety and quality management system standards, the maintenance of which indicates to customers certain quality and operational norms. Customers may rely on contractual assurances that we make with respect to such certifications to transact business. Failure to comply with these standards can lead to observations of non-compliance or even suspension of such certifications. If we were to fail to obtain or maintain such a certification it could result in breach of contracts or difficulty in obtaining new customer contracts, which could adversely affect our business.

We may be unable to obtain relevant regulatory approvals for the commercialization of our aircraft, motors or subsystems, either in the United States or in foreign markets.

We may be unable to obtain the regulatory approvals needed for the commercialization of our aircraft, motors or subsystems in accordance with our business plan. The commercialization of new aircraft requires certain regulatory authorizations and certifications, including Type Certification, Production Certification and FAA Airworthiness Certification. While we have received FAA special airworthiness certificates for certain CX300 aircraft, and while we anticipate being able to obtain the required authorizations and certifications with respect to our aircraft or motors, we may be unable to do so on the timeline we project or at all. Circumstances outside of our control could delay the receipt of our required certifications. For example, FAA staffing depends, in large part, on the annual appropriations process and the agency’s ability to retain and recruit sufficient resources with relevant experience and expertise. Failure to pass an annual appropriation bill has in the past resulted in temporary government shutdowns. A future shutdown, or a failure by Congress to pass an FAA reauthorization bill (or extension) could delay the rulemaking and certification process. Additionally, recent focus on reducing the size of the federal workforce could negatively impact the availability of resources within the FAA which could delay our progress towards certification.

We also plan to pursue regulatory approval of our aircraft, motors and other offerings in other countries. While many of these countries have established processes for validating a Type Certification issued by the FAA, others are developing new processes to leverage our work with the FAA and provide a path for approval of initial operations that could precede Type Certification in the United States. The regulatory agencies charged with granting approvals with respect to our aircraft and other offerings in other countries may be subject to many of the same funding, staffing and other risks that exist in the United States. Additionally, pursuing certification and operations outside the United States is subject to additional risks, including, but not limited to, other regulatory regimes being less familiar with or to us or having less experience in certifying and approving new and novel aircraft or technology. If we fail to obtain any of the required authorizations or certificates, or do so in a timely manner, or any of these authorizations or certificates are modified, suspended or revoked after we obtain them, we may be unable to launch our commercial rollout or do so on the timelines we project and there may be a resultant adverse impact on our business, results of operations, financial condition and prospects.

We are subject to stringent U.S. export and import control laws and regulations, which may change. We may be unable to comply with these laws and regulations or U.S. government licensing policies, or to secure required authorizations in a timely manner.

Certain aspects of our business are subject to stringent U.S. import and export control laws and regulations as well as economic sanctions laws and regulations. We are required to import and export our products, software, technical data, technology and services, and run our operations in the United States, in full compliance with such laws and regulations, which may include the EAR, the ITAR and the economic sanctions administered by the Treasury Department’s Office of Foreign Assets Control. Similar laws may impact our business in other jurisdictions. These trade controls prohibit, restrict or regulate our ability to, directly or indirectly, export or transfer certain hardware, software, technical data, technology, software or services to certain countries and territories, entities and individuals, and for certain end uses. In addition, the Treasury Department’s Committee on Foreign Investment in the U.S. (“CFIUS”) has the authority to review direct and indirect investments in U.S. businesses by foreign persons. Among other things, CFIUS is empowered to require certain foreign investors to make mandatory filings, charge filing fees related to such filings and self-initiate national security reviews of investments if the parties to that investment choose not to file voluntarily. In the case that CFIUS determines an investment to be a threat to national security, CFIUS has the power to place restrictions, conditions or limitations on or even prohibit, or require divestment of, the investment. If we are found to be in violation of these laws and regulations it could result in civil and criminal penalties, including the loss of export or import privileges, debarment and reputational harm.

Pursuant to these trade control laws and regulations, we are required, among other things, to (i) determine the proper licensing jurisdiction and export classification of products, software and technical data/technology, (ii) obtain licenses or other forms of authorization to conduct our business and (iii) manage physical access and security accordingly. These requirements include the need to get permission to release controlled technology to foreign person employees and other foreign persons in the United States. Changes in U.S. trade control laws and regulations, or reclassifications of our products or technologies, may restrict our operations. The inability to secure and maintain necessary licenses and other authorizations could negatively impact our ability to compete successfully or to operate our business as planned. Any changes in the export control regulations or U.S. licensing policy, such as those necessary to implement U.S. commitments to multilateral control regimes, may restrict our operations. Given the great discretion the government has in issuing or denying such authorizations, there can be no assurance we will be successful in our future efforts to secure and maintain necessary licenses, registrations or other regulatory approvals which may have an adverse impact on our business, results of operations, financial condition and prospects.

In addition, the global economy has recently seen a rise in tariffs and threats of tariffs. While tariffs have not had a material impact on our business, results of operations, financial condition or prospects to date, new tariffs could increase the costs of raw materials and other goods, both for us and our suppliers, which could impact our business, particularly as we begin to scale our manufacturing operations.

We could incur significant costs in complying with EHS laws and regulations and could be adversely affected by liabilities or obligations imposed under such laws and regulations.

We are subject to a variety of increasingly stringent foreign, federal, state and local EHS laws, regulations and ordinances relating to the protection of the environment, including those relating to emissions to air and other environmental media, discharges (including storm water) to surface and subsurface waters, safe drinking water, wildlife preservation, operational constraints like noise abatement, including relating to aircraft noise, and the use, management, disposal and release of, and exposure to, hazardous substances, oils and waste materials. We could incur significant costs, including fines, cleanup costs and third-party claims, as a result of violations of or liabilities under these laws and regulations, and may also incur significant costs to achieve or maintain compliance in the future. In addition, fines and penalties may be imposed for non-compliance with applicable EHS laws and regulations and the failure to have or to comply with the terms and conditions of required permits. From time to time, our operations may not be in full compliance with the terms and conditions of our permits or

60

##### Table of Contents

licenses and we can provide no assurance that the cost of achieving and maintaining compliance with EHS laws and requirements will not become material in the future.

In addition, it is difficult to accurately predict the nature and extent of environmental liabilities and obligations that may result from laws or regulations adopted in the future and how existing or future laws and regulations will be administered or interpreted. For example, changes in EHS laws, including laws relating to energy consumption and aircraft noise, could require additional investments in manufacturing designs, which may be more expensive or difficult to manufacture, and could increase environmental compliance expenditures. The adoption of new EHS regulations could result in increased costs and have an adverse impact on our results of operations.

Governmental regulations and reporting regarding aircraft noise, including those adopted by the FAA, the International Civil Aviation Organization (“ICAO”) and other jurisdictions, apply based on where the relevant aircraft is registered and operated. These regulations, as well as the potential for new and more stringent regulations, could limit the economic life of our aircraft, reduce their value, limit our ability to sell non-compliant aircraft or, if aircraft modifications are permitted, require us to make significant additional investments in the aircraft to make them compliant.

We may also be subject to potential strict, joint and several liability for the investigation and remediation of contamination, including contamination caused by other parties, that may exist at properties we currently own, lease or operate and previously owned, leased or operated and at other properties where we or our predecessors have arranged for the disposal of hazardous substances. We may incur significant costs, including cleanup costs and other environmental liabilities, as a result of any environmental conditions that are existing or discovered or obligations that are imposed in the future. From time to time, we may be involved in administrative and judicial proceedings, investigation and remediation activities and other claims relating to these and other environmental matters. As a result, the aggregate amount of future cleanup costs and other environmental liabilities and obligations could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are and will be subject to rapidly changing and increasingly restrictive Privacy Laws and other obligations relating to privacy, data protection and data security, which may be costly and difficult to comply with.

We are and will be collecting, using, disclosing or otherwise processing the personal information of customers, employees and others in the course of operating our business. These activities are or may become regulated by a variety of domestic and foreign laws and regulations relating to privacy, data protection and data security, which are complex, rapidly evolving and increasingly restrictive. Several states in the United States and foreign countries have granted their respective residents expanded rights related to their personal information. For example, the California Consumer Privacy Act, as amended by the California Privacy Rights Act, grants California residents the right to access and request the deletion of their personal information and receive detailed reports of how their personal information is processed, and provides a private right of action for certain data breaches involving the loss of personal data. Such laws and any laws adopted in the future could have potentially conflicting requirements that would make compliance challenging. Despite our best efforts, we may not be successful in complying with the rapidly evolving privacy, data protection and data security requirements. The existence of comprehensive privacy laws in various jurisdictions will make our compliance obligations more complex and costly and may increase the likelihood that we may be subject to enforcement actions or otherwise incur liability for noncompliance. Any actual or perceived non-compliance could result in litigation and proceedings against us by governmental entities, customers or others, which could result in fines, civil or criminal penalties, limited ability or inability to operate our business, offer our products and services or market our technologies in certain jurisdictions, negative publicity and harm to our brand and reputation, which could have a material adverse effect on our business, results of operations, financial condition or prospects. See also “—Risks Related to Our Business and Industry—We are subject to evolving Privacy Laws, which subjects us to

##### Table of Contents

a number of potential regulatory and reputational risks. We may face investigations, fines and sanctions as a result of our or our service providers’ actual or perceived failure to comply with the Privacy Laws and incur increased operational costs in order to ensure future compliance.”

We currently have subsidiaries located outside of the United States and plans for international operations in the future, which could subject us to political, operational and regulatory challenges.

While our primary operations are in the United States, we currently have a subsidiary in each of Canada, Ireland and the UAE, certain of which are engaged in limited test manufacturing, research and development and other activities, and we may eventually expand our international operations further. We also have established relationships with suppliers and potential partners in select international markets and have begun working with regulators in other countries to pursue commercialization opportunities in those markets. International operations are subject to a number of risks, including regulations that may differ from or be more stringent than analogous U.S. regulations, local political or economic instability, cross-border political tensions, import and export compliance, privacy, data protection, information security, labor and employment matters and exposure to potential liabilities under anti-corruption or anti-bribery laws and similar laws and regulations. If any of these risks materialize, it could adversely impact our business.

Changes in tax laws or regulations that are applied adversely to us may have a material adverse effect on our business, results of operations, cash flows or financial condition.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. Future changes in corporate tax rates, the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings and the deductibility of expenses could have a material impact on the value of our deferred tax assets, could result in significant one-time charges, and could increase our future U.S. tax expense.

Risks Related to Our Indebtedness

The covenants in our Credit Agreement may restrict our operations, and failure to comply with the covenants in our Credit Agreement could adversely impact our business.

Our Credit Agreement and the other financing documentation entered into in connection therewith impose restrictive covenants that may limit our ability to operate our business, including, without limitation, covenants that limit our ability to create liens and dispose of assets. If we violate these or any other covenants set forth therein, any loans outstanding under the Credit Agreement could become due and payable prior to their stated maturity dates, and Ex-Im could proceed against the collateral granted in connection therewith by exercising its rights and remedies with respect to its first-priority liens on and security interests in our production facility and such other collateral. These restrictions may also limit our flexibility to plan for, or react to, changes in our business and industry and our ability to borrow additional funds and pursue other business opportunities or strategies that we would otherwise consider to be in our best interests.

We may not be able to generate sufficient cash to service all of our indebtedness or repay such indebtedness when due, and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on or to refinance our indebtedness obligations depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to financial, business, legislative, regulatory, and other factors, some of which are beyond our control. We cannot be sure that our business will generate sufficient cash flows from operating activities, or that future borrowings will be available, to permit us to pay the principal, premium, if any, and interest on our indebtedness.

62

##### Table of Contents

If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital, or restructure or refinance our indebtedness. The loans outstanding under our $170.1 million credit facility established pursuant to the Credit Agreement (the “Credit Facility”) mature in December 2038. We may not be able to implement any such alternative measures, if necessary, on commercially reasonable terms or at all and, even if successful, those alternative actions may be on less favorable terms, may occur under unfavorable market conditions, and/or may not allow us to meet our scheduled debt service obligations. The Credit Agreement restricts our ability to dispose of assets and use the proceeds from those dispositions and may also restrict our ability to raise debt or equity capital to be used to repay other indebtedness when it becomes due. We may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Credit Facility.”

Our inability to generate sufficient cash flows to satisfy our debt obligations, or to refinance our indebtedness on commercially reasonable terms or at all, would have a material adverse effect on our business, results of operations, financial condition and prospects.

If we cannot make scheduled payments on our indebtedness under our Credit Facility, we will be in default, and Ex-Im could cause any loans outstanding under our Credit Agreement to become due and payable prior to their stated maturity date and/or exercise its rights and remedies with respect to its first-priority liens on and security interests in our production facility and the other collateral granted in connection with our Credit Agreement, and as a result thereof, we could be forced into bankruptcy or liquidation.

Risks Related to This Offering, Ownership of Our Class A Common Stock and Our Capital Structure

There is no existing market for the Class A common stock, and a trading market that will provide stockholders with adequate liquidity may not develop. The price of the Class A common stock may fluctuate significantly, and stockholders could lose all or part of your investment.

We have applied to list the Class A common stock on the NYSE under the symbol “BETA.” However, there is currently no public trading market for the Class A common stock. We do not know the extent to which investor interest will lead to the development of an active trading market or how liquid that market might become. If an active trading market does not develop, you may have difficulty reselling shares of Class A common stock at or above the initial public offering price, or at all. Additionally, the lack of liquidity may result in wide bid-ask spreads, contribute to significant fluctuations in the market price of the Class A common stock and limit the number of investors who are able to buy the Class A common stock.

The initial public offering price for the Class A common stock offered hereby will be determined by discussions between us and the representatives of the underwriters and may not be indicative of the market price of the Class A common stock that will prevail in the trading market. Consequently, stockholders may not be able to sell shares of the Class A common stock at prices equal to or greater than the price paid by stockholders in this offering.

The following is a non-exhaustive list of factors that could affect the market price of the Class A common stock:

| • |  | our operating and financial performance;

| • |  | quarterly variations in the rate of growth of our financial indicators, such as net income per share, net income and revenues;

| • |  | the public reaction to our press releases, our other public announcements and our filings with the SEC;

| • |  | strategic actions by our competitors;

| • |  | our failure to meet revenue or earnings estimates by research analysts or other investors;

63

##### Table of Contents

| • |  | changes in revenue or earnings estimates, or changes in recommendations or withdrawal of research coverage, by equity research analysts;

| • |  | speculation in the press or investment community;

| • |  | the failure of research analysts to cover the Class A common stock;

| • |  | sales of the Class A common stock by us or other stockholders, or the perception that such sales may occur;

| • |  | changes in accounting principles, policies, guidance, interpretations or standards;

| • |  | additions or departures of key management personnel;

| • |  | actions by our stockholders;

| • |  | general market conditions, including fluctuations in commodity prices;

| • |  | domestic and international economic, legal and regulatory factors unrelated to our performance; and

| • |  | the realization of any risks described under this “Risk Factors” section.

The stock markets in general have experienced extreme volatility that has often been unrelated to the operating performance of companies. These broad market fluctuations may adversely affect the trading price of the Class A common stock. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. Such litigation, if instituted against us, could result in substantial costs, divert our management’s attention and resources and harm our business, results of operations, financial condition and prospects.

We are controlled by Kyle Clark, our Chief Executive Officer and a member of our Board, whose interests in our business may conflict with ours or yours.

The Class B common stock is beneficially owned by Kyle Clark, our Chief Executive Officer and a director of the Company, whose interests may differ from or conflict with the interests of our other stockholders. Each share of Class A common stock is entitled to one vote per share. Each share of our Class B common stock is entitled to 40 votes per share. Following this offering, Mr. Clark will beneficially own all of the issued and outstanding shares of Class B common stock and, accordingly, will own approximately    % of our outstanding capital stock and control approximately    % of the voting power of our outstanding capital stock (assuming no exercise of the underwriters’ option to purchase additional shares). As a result, Mr. Clark will have the ability to exercise control over our affairs, including control over the outcome of all matters submitted to our stockholders for approval, including the election of directors and significant corporate transactions. The directors so elected, including Mr. Clark for so long as he continues to stand for reelection and serve as our director, will have the authority, subject to the terms of our indebtedness and applicable rules and regulations, to issue additional stock, implement stock repurchase programs, declare dividends and make other decisions. Mr. Clark 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 example, Mr. Clark may have differing incentives from other stockholders that could influence his decisions regarding whether and when to cause us to dispose of assets, incur new or refinance existing indebtedness or take other actions. Additionally, Mr. Clark may cause us to make strategic decisions or pursue acquisitions that could involve risks to you or may not be aligned with your interests. This concentrated control may have the effect of delaying, preventing or deterring a change in control of the Company, could deprive our stockholders of an opportunity to receive a premium on their shares of Class A common stock as part of a sale of the Company and might ultimately affect the market price of the Class A common stock. Moreover, while stockholders would generally be entitled to dissenters’ rights of appraisal under applicable Delaware law, there are certain exceptions. As a result, Mr. Clark will be able to effectively control us.

64

##### Table of Contents

Future transfers of Class B common stock will generally result in those shares converting into shares of Class A common stock, subject to limited exceptions described in our Amended and Restated Certificate of Incorporation, including transfers to immediate family members (including upon Mr. Clark’s death), trusts (including grantor retained annuity trusts) for which the stockholder or their immediate family member serves as trustee and partnerships, corporations and other entities exclusively owned by Mr. Clark or his immediate family. In addition, each share of Class B common stock will convert automatically into one share of Class A common stock upon the death or disability of Mr. Clark or Mr. Clark’s ceasing to provide services to the Company as an officer, employee or director of the Company.

Certain of our directors and members of management may have interests that are different from, or in addition to, those of other stockholders.

We have from time to time entered into transactions, arrangements or relationships with our directors, members of management or their respective affiliates. These transactions have in the past included, and in the future could include, without limitation, the purchase, sale or leasing of real or other property, the provision or receipt of financing or other business dealings. There is a risk that such transactions may not be on terms as favorable to us as those that could be obtained from unrelated third parties. Even if such transactions are subject to approval by disinterested directors or are otherwise conducted in accordance with applicable laws and policies, the existence of these relationships may give rise to actual or perceived conflicts of interest. These conflicts could result in decisions that are not in our or your best interests, and could adversely affect our business, financial condition or prospects. See “Certain Relationships and Related Party Transactions.”

We expect that provisions in our Amended and Restated Certificate of Incorporation relating to certain relationships and transactions will address certain actual or potential conflicts of interest between us, on the one hand, and our directors, officers or employees, on the other hand. By becoming our stockholder, you will be deemed to have notice of, and consented to, these provisions.

Upon the listing of the Class A common stock on the NYSE, we will be a “controlled company” within the meaning of the NYSE rules and, as a result, will qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.

After completion of this offering, Kyle Clark, our Chief Executive Officer and a member of our Board, will continue to control a majority of the combined voting power of all classes of our stock entitled to vote generally in the election of directors through his ownership of the Class B common stock. As a result, we will be a “controlled company” within the meaning of the NYSE corporate governance standards. Under these rules, a company of which more than 50% of the voting power in the election of directors is held by an individual, group or another company is a “controlled company” may elect not to comply with certain corporate governance requirements, including those which require, within one year of the date of the listing of the Class A common stock:

| • |  | a majority of our Board consist of independent directors;

| • |  | our Board have a compensation committee that is comprised entirely of independent directors; and

| • |  | our Board have a nominating and corporate governance committee that is comprised entirely of independent directors.

We currently do not plan to establish a compensation committee or nominating and corporate governance committee composed entirely of independent directors as permitted by these exemptions. Accordingly, you will not have the same protections afforded to stockholders of companies that are subject to all of these corporate governance requirements. See “Management—Controlled Company Exception.”

Management will have broad discretion over the use of our proceeds from this offering.

The principal purposes of this offering include increasing our capitalization and financial flexibility, creating a public market for the Class A common stock, thereby enabling access to the public equity markets by our employees and stockholders, obtaining additional capital and increasing our visibility in the marketplace. We intend to use our net proceeds from this offering for general corporate purposes. See “Use of Proceeds.” We cannot specify with certainty the particular uses of our net proceeds to us from this offering. Accordingly, we will have broad discretion in using our proceeds and might not be able to obtain a significant return, if any, on investment of our net proceeds. Investors in this offering will need to rely upon the judgment of our management with respect to the use of our proceeds. If we do not use our net proceeds from this offering effectively, our business, results of operations, financial condition and prospects could be harmed.

Our issuance of additional capital stock or other equity-related securities in connection with financings, acquisitions, investments, our LTIP or otherwise could dilute each stockholder’s ownership interest or adversely affect the market price of the Class A common stock.

We may raise capital through equity financings in the future. As part of our business strategy, we may acquire or make investments in complementary companies, products or technologies and issue equity securities to pay for any such acquisition or investment. We expect to issue additional equity securities in the future in connection with one or more of these practices. We also utilize equity-based compensation as a key component of our compensation program. Any additional issuances of common stock would have the effect of diluting our earnings per share and our existing stockholders’ respective individual ownership percentages and lead to volatility in the market price of the Class A common stock. We cannot predict the effect that future issuances of shares of common stock or other equity-related securities would have on the market price of the Class A common stock.

We do not intend to pay dividends following the completion of this offering and may never pay dividends.

Following the completion of this offering, our Board may elect to declare cash dividends on the Class A common stock, subject to our compliance with applicable law. The declaration and amount of any future dividends is subject to the discretion of our Board, and we have no obligation to pay any dividends at any time. We do not intend to pay dividends following the completion of this offering and may never pay dividends. We have not adopted, and do not currently expect to adopt, a written dividend policy. Our future dividend policy will be based on the operating results and capital needs of our business, and any future earnings may be retained to finance our future expansion and for the implementation of our business plan.

The payment of dividends is dependent on, among other things, economic conditions, our financial condition, results of operations, projections, liquidity and earnings and legal requirements. Any financing arrangements or debt arrangements that we enter into in the future may also include restrictive covenants that limit our ability to pay dividends.

As an investor, you should take note of the fact that a lack of a dividend may affect the market value of the Class A common stock and could affect the value of any investment.

The multi-class structure of our common stock may adversely affect the trading market for the Class A common stock.

We cannot predict whether our multi-class structure will result in a lower or more volatile market price of the Class A common stock, adverse publicity or other adverse consequences. Certain stock index providers exclude or limit the ability of companies with multi-class share structures from being added to certain of their indices. In addition, several stockholder advisory firms and large institutional investors oppose the use of multiple class structures. As a result, the multi-class structure of our common stock may make us ineligible for

66

##### Table of Contents

inclusion in certain indices and may discourage such indices from selecting us for inclusion may cause stockholder advisory firms to publish negative commentary about our corporate governance practices or otherwise seek to cause us to change our capital structure, and may result in large institutional investors not purchasing shares of the Class A common stock. Given the sustained flow of investment funds into passive strategies that seek to track certain indices, any exclusion from certain stock indices could result in less demand for the Class A common stock. Any actions or publications by stockholder advisory firms or institutional investors critical of our corporate governance practices or capital structure could also adversely affect the value of the Class A common stock.

Future sales of the Class A common stock in the public market could reduce the market price of the Class A common stock, and any additional capital raised by us through the sale of equity or convertible or exchangeable securities may dilute your ownership in us.

We may sell additional shares of Class A common stock in subsequent public offerings. We may also issue additional shares of Class A common stock or convertible or exchangeable securities. After the completion of this offering, we will have outstanding shares of the Class A common stock (or shares of Class A common stock if the underwriters exercise in full their option to purchase additional shares of Class A common stock), of which our directors and officers will own shares or approximately % (or % if the underwriters exercise in full their option to purchase additional shares of Class A common stock) of the total outstanding shares of Class A common stock, all of which will be restricted from immediate resale under the federal securities laws and subject to the lock-up agreements with the underwriters as described in “Underwriting” section of this prospectus, but which may be sold into the market in the future. See “Shares Eligible for Future Sale.” After the completion of this offering, our Chief Executive Officer will own shares of the Class B common stock or approximately % of our total outstanding shares of common stock, all of which will be restricted from immediate resale under the federal securities laws and subject to the lock-up agreement with the underwriters described in the “Underwriting” section of this prospectus but may be sold into the market in the future. See “Shares Eligible for Future Sale.”

Furthermore, in connection with this offering, we intend to file a registration statement with the SEC on Form S-8 providing for the registration of shares of the Class A common stock issued or reserved for issuance under our LTIP. Subject to the satisfaction of vesting conditions, the expiration of lock-up agreements and the requirements of Rule 144 under the Securities Act (“Rule 144”), shares registered pursuant to the registration statement on Form S-8 will be available for resale immediately in the public market without restriction.

We cannot predict the size of future issuances of the Class A common stock or securities convertible into or exchangeable for Class A common stock or other securities of the Company, or the effect, if any, that future issuances and sales of shares of the Class A common stock will have on the market price of the Class A common stock. Sales of substantial amounts of our Class A common stock (including shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices of the Class A common stock.

The underwriters of this offering may waive or release parties to the lock-up agreements entered into in connection with this offering, which could adversely affect the price of the Class A common stock.

Prior to this offering, we, all of our directors and executive officers and , will enter into lock-up agreements with respect to their Class A common stock (including any Class A common stock into or for which securities of the Company held by such parties are convertible or exchangeable), pursuant to which, subject to certain exceptions, they are subject to certain resale restrictions for a period of 180 days following the effectiveness date of the registration statement of which this prospectus forms a part. Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC may, at any time and without notice, release all or any portion of the Class A common stock subject to the foregoing lock-up agreements. If the restrictions under the lock-up agreements are waived, then Class A common stock will be available for sale into the public markets, subject to any applicable

67

##### Table of Contents

restrictions imposed by the federal securities laws, which could cause the market price of the Class A common stock to decline and impair our ability to raise capital. See “Underwriting.”

Terms of subsequent financings may adversely impact stockholder equity.

If we raise more equity capital from the sale of Class A common stock, such equity could be offered at a price more favorable than the then-current market price of the Class A common stock. If we issue debt securities, the holders of the debt will have a claim to our assets that would be senior to the rights of the holders of shares of Class A common stock until the debt is paid. Interest on these debt securities would increase costs and could negatively impact our operating results.

In accordance with Delaware law and the provisions of our Amended and Restated Certificate of Incorporation, we may issue one or more classes or series of preferred stock that ranks senior in right of dividends, liquidation or voting relative to the Class A common stock. Preferred stock may have such designations, preferences, limitations and relative rights, including preferences relative to the Class A common stock in respect of dividends and distributions, as our Board may determine, and the issuance of preferred stock would dilute the ownership of our existing stockholders. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of the Class A common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders of preferred stock could affect the residual value of our common stock. The terms of any series of preferred stock may also reduce or eliminate the amount of cash available for payment of dividends to holders of the Class A common stock or subordinate the claims of such holders to our assets in the event of our liquidation. The Class A common stock will not be subject to redemption or sinking fund provisions.

If securities analysts or industry analysts were to downgrade the Class A common stock, publish negative research or reports or fail to publish reports about our business, our competitive position could suffer, and the price and trading volume of the Class A common stock could decline.

The trading market for the Class A common stock will, to some extent, depend on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts who cover us should downgrade the Class A common stock or publish negative research or reports, cease coverage of the Company or fail to regularly publish reports about our business, our competitive position could suffer, and the price and trading volume of the Class A common stock could decline.

As a public company, we will be obligated to develop and maintain proper and effective internal control over financial reporting. The requirements of being a public company, including compliance with the reporting requirements of the Exchange Act, and the requirements of the Sarbanes-Oxley Act, may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner, which could adversely affect investor confidence in our company and, as a result, the value of the Class A common stock.

As a public company, we will need to comply with new laws, regulations and requirements, certain corporate governance provisions of Sarbanes-Oxley Act, related regulations of the SEC and the requirements of the NYSE, with which we were not required to comply as a private company. Complying with these statutes, regulations and requirements will occupy a significant amount of our time and will significantly increase our costs and expenses. We will need to:

| • |  | institute a more comprehensive compliance function to test and conclude on the sufficiency of our internal control over financial reporting;

68

##### Table of Contents

| • |  | comply with rules promulgated by the NYSE;

| • |  | prepare and distribute periodic public reports;

| • |  | establish new internal policies, such as those relating to insider trading; and

| • |  | involve and retain to a greater degree outside professionals in the above activities.

Furthermore, while we generally must comply with Section 404 of the Sarbanes-Oxley Act, we are not required to have our independent registered public accounting firm attest to the effectiveness of our internal controls until our first annual report subsequent to our ceasing to be an “emerging growth company.” We may not be required to have our independent registered public accounting firm attest to the effectiveness of our internal controls until as late as our annual report for the year ending December 31, 2030. At any time, we may conclude that our internal controls, once tested, are not operating as designed or that our system of internal controls does not address all relevant financial statement risks. Once required to attest to control effectiveness, our independent registered public accounting firm may issue a report that concludes it does not believe our internal control over financial reporting is effective. Compliance with Sarbanes-Oxley Act requirements may strain our resources, increase our costs and distract management, and we may be unable to comply with these requirements in a timely or cost-effective manner.

Taking advantage of the reduced disclosure requirements applicable to “emerging growth companies” may make the Class A common stock less attractive to investors.

We qualify as an “emerging growth company” as defined in the JOBS Act. An emerging growth company may take advantage of certain reduced reporting and other requirements that are otherwise applicable generally to public companies. Pursuant to these reduced disclosure requirements, emerging growth companies are not required to, among other things, comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, provide certain disclosures regarding executive compensation, holding stockholder advisory votes on executive compensation or obtain stockholder approval of any golden parachute payments not previously approved. In addition, emerging growth companies have longer phase-in periods for the adoption of new or revised financial accounting. We will cease to be an emerging growth company upon the earliest of (i) the last day of the fiscal year in which we have $1.235 billion or more in annual revenues; (ii) the date on which we become a “large accelerated filer” (the fiscal year-end on which the total market value of our common equity securities held by non-affiliates is $700 million or more as of June 30); (iii) the date on which we issue more than $1.0 billion of non-convertible debt securities over a three-year period; or (iv) the last day of the fiscal year following the fifth anniversary of this offering. We may take advantage of all of the reduced reporting requirements and exemptions until we are no longer an emerging growth company.

We have elected to take advantage of the extended transition period to comply with new or revised accounting standards under Section 107 of the JOBS Act. Electing to use the phase-in periods permitted by this election may make it difficult to compare our financial statements to those of non-emerging growth companies and other emerging growth companies that have opted out of the longer phase-in periods under Section 107 of the JOBS Act and who will comply with new or revised financial accounting standards. We cannot predict if investors will find our Class A common stock less attractive if we rely on these exemptions. If some investors find the Class A common stock less attractive as a result, there may be a less active trading market for the Class A common stock and the price of the Class A common stock may be more volatile. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies.

Investors in this offering will experience immediate and substantial dilution of $      per share.

Based on an assumed initial public offering price of $ per share (the midpoint of the price range set forth on the cover of this prospectus), purchasers of the Class A common stock in this offering will

experience an immediate and substantial dilution of $ per share in the net tangible book value per share of Class A common stock from the initial public offering price, and our historical and as adjusted net tangible book deficit as of     , 2025 would be $ per share. See “Dilution.”

Provisions of our corporate governance documents could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our current management or members of our Board, even if beneficial to our stockholders.

In addition to certain provisions of the Delaware General Corporation Law (as amended, the “DGCL”) that apply to us, our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws will contain provisions that could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our stockholders. Among other things, these provisions:

| • |  | will allow our Board to authorize the issuance of undesignated preferred stock, the terms of which may be established and the shares of which may be issued without stockholder approval, and which may include supermajority voting, special approval, dividend or other rights or preferences superior to the rights of other stockholders;

| • |  | provide for a classified Board with staggered three-year terms;

| • |  | provide that, at any time when the Class B Common Stockholder controls, in the aggregate, less than  % in voting power of shares of common stock entitled to vote generally in the election of directors, directors may only be removed for cause and only by the affirmative vote of holders of at least  % in voting power of all the then-outstanding shares of common stock entitled to vote thereon, voting together as a single class; and

| • |  | establish advance notice requirements for nominations for elections to our Board or for proposing matters that can be acted upon by stockholders at stockholder meetings.

These and other provisions of our corporate governance documents and Delaware law could make it more difficult for stockholders or potential acquirers to obtain control of our Board or initiate actions that are opposed by our then-current Board, including actions to delay or impede a merger, tender offer or proxy contest involving the Company. The existence of these provisions could negatively affect the price of the Class A common stock and limit opportunities for you to realize value in a corporate transaction.

We may be subject to securities litigation, activist investors and short-selling campaigns, which are expensive and could divert management attention.

Following the completion of this offering, the market price of the Class A common stock may be volatile. Companies that have experienced volatility in the market price of their stock have, in the past, been subject to securities class action litigation, activist investor campaigns and short-selling. We may be the target of these types of activities in the future, any for which could result in substantial costs and divert management’s attention from other business concerns, which could seriously harm our business.

Our Amended and Restated Certificate of Incorporation will designate the Court of Chancery of the State of Delaware (the “Delaware Court of Chancery”) as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to bring a claim in a different judicial forum for disputes with us or our directors, officers, employees or agents.

Our Amended and Restated Certificate of Incorporation will provide that unless we consent in writing to the selection of an alternative forum, the Delaware Court of Chancery will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a duty (including any fiduciary duty) owed by any of our directors,

70

##### Table of Contents

officers, employees, agents or stockholders to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws, (iv) any action to interpret, apply, enforce or determine the validity of our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws, (v) any action asserting a claim against us or any of our directors, officers, employees, agents or stockholders that is governed by the internal affairs doctrine, (vi) any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL, or (vii) any action as to which the DGCL confers jurisdiction on the Delaware Court of Chancery; provided that the forum selection provision in our Amended and Restated Certificate of Incorporation identifies the federal district courts of the United States as the exclusive forum for any complaint asserting a cause of action arising under the Securities Act or the Exchange Act unless we consent in writing to the selection of an alternative forum. Notwithstanding the above, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. We cannot be certain that a court would enforce our exclusive forum provision as it relates to complaints asserting a cause of action arising under the Securities Act. This choice of forum may limit a stockholder’s ability to bring a claim in a different judicial forum for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such persons. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law or the Securities Act, as applicable, for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors, officers, employees or agents. Alternatively, if a court were to find any of the forum selection provisions contained in our Amended and Restated Certificate of Incorporation to be inapplicable or unenforceable, we may incur additional costs associated with having to litigate such action in other jurisdictions, which could have an adverse effect on our business, results of operations, cash flows, financial condition and prospects and result in a diversion of the time and resources of our employees, management and Board.

There can be no assurance that we will be able to comply with the continued listing standards of the NYSE following the completion of this offering. If we are unable to comply with its continued listing requirements, the NYSE may delist the Class A common stock from trading on its exchange, which could limit investors’ ability to transact in the Class A common stock and subject us to additional trading restrictions.

We have applied to list the Class A common stock on the NYSE under the symbol “BETA.” However, we cannot assure you that the Class A common stock will continue to be listed on the NYSE following the completion of this offering. We will be required to demonstrate compliance with the NYSE’s continued listing requirements in order to maintain the listing of the Class A common stock on the NYSE. If the NYSE delists the Class A common stock from trading on its exchange and we are not able to list the Class A common stock on another national securities exchange, the Class A common stock could be quoted on an over-the-counter market. If this were to occur, we could face significant adverse consequences, including:

| • |  | a limited availability of market quotations for our securities;

| • |  | reduced liquidity for the Class A common stock;

| • |  | a determination that the Class A common stock is a “penny stock,” which would require brokers trading in the Class A common stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for the Class A common stock;

| • |  | a limited amount of news and analyst coverage; and

| • |  | a decreased ability to issue additional securities or obtain additional financing in the future.

If we are deemed to be an investment company under the Investment Company Act of 1940, our results of operations could be harmed.

Under the Investment Company Act of 1940, as amended (the “Investment Company Act”), absent an applicable exemption, a company generally will be deemed to be an “investment company” if (a) it is in the business of investing, reinvesting, owning, holding or trading in securities and (b) it owns or proposes to acquire “investment securities” having a value exceeding 40% of its total assets (other than U.S. government securities and cash items) on an unconsolidated basis (such second prong, the “40% Test”). We do not believe that we or any of our subsidiaries are an “investment company” for purposes of the Investment Company Act, including in part, because neither we nor any of our subsidiaries are in the business of investing, reinvesting, owning, holding or trading in securities, as required under Section 3(a)(1)(C) of the Investment Company Act, and because we qualify for the safe harbor from “investment company” status provided in Rule 3a-8 under the Investment Company Act.

We are engaged primarily in developing an all-electric, conventional and vertical take-off and landing electric aircraft, and our historical development, the activity of our officers and directors, the nature of our present assets, the sources of our present income and the public perception of the nature of our business all support the conclusion that we are an operating company and not an investment company. Further, we qualify for the nonexclusive safe harbor from the definition of “investment company” provided in Rule 3a-8 under the Investment Company Act, which applies to certain research and development companies. We currently conduct, and intend to continue to conduct, our operations so that neither we, nor any of our subsidiaries, is required to register as an “investment company” under the Investment Company Act. If we were obligated to register as an “investment company,” we would have to comply with a variety of substantive requirements under the Investment Company Act that impose, among other things, limitations on capital structure, restrictions on specified investments, prohibitions on transactions with affiliates and compliance with reporting, record keeping, voting, proxy disclosure and other rules and regulations that would increase our operating and compliance costs, could make it impractical for us to continue our business as contemplated, and could have a material adverse effect on our business.

General Risk Factors

Our business may be adversely affected by the current global political and macroeconomic challenges, including the tariffs, effects of inflation, volatile interest rates or an economic downturn or recession.

Current global political and macroeconomic conditions and the effects thereof, including inflation, volatile interest rates, changes in trade agreements or regulations, tariffs, uncertainty with respect to the federal budget and federal debt ceiling and potential government shutdowns related thereto, actual or perceived instability in the global banking sector, the war in Ukraine and conflicts in the Middle East, supply chain issues and any economic downturn or recession in certain regions or worldwide have, and may continue to, adversely affect our business, results of operations, financial condition and prospects. The existence of inflation in certain economies has resulted in, and may continue to result in, volatile interest rates and capital costs, supply shortages, increased costs of labor, certain components, manufacturing and shipping as well as weakening exchange rates and other similar effects. As a result, we may experience cost increases. Although we take measures to mitigate the effects of macroeconomic challenges, if these measures are not effective, our business, results of operations, liquidity, financial condition and prospects could be materially adversely affected. Even if such measures are effective, there could be a delay between the adverse effects of macroeconomic conditions and the timing of when those beneficial actions impact our business, results of operations, financial condition and/or prospects.

##### Table of Contents

We have been, and may in the future be, adversely affected by public health threats, the duration and economic, governmental and social impact of which is difficult to predict, which could significantly harm our business, results of operations, financial condition and prospects.

We face various risks related to public health issues, including epidemics, pandemics and other outbreaks that could harm our operations and financial results. For example, COVID-19 created a disruption in the manufacturing, delivery and overall supply chain of aircraft manufacturers and suppliers. The extent to which the health epidemics or pandemics can impact our business, results of operations, financial condition and prospects will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration and spread of such health epidemics or pandemics, their severity, the actions taken by governments and others in response to such health epidemics and pandemics and how quickly and to what extent normal economic and operating activities can resume. Even after health epidemics or pandemics have subsided, we may continue to experience an adverse impact to our business because of such public health threats, including ongoing supply chain shortages.

USE OF PROCEEDS

We will receive net proceeds of approximately $     million (or approximately $     million if the underwriters exercise in full their option to purchase additional shares of Class A common stock) from the sale of the Class A common stock by us in this offering, assuming an initial public offering price of $     per share (the midpoint of the price range set forth on the cover page of this prospectus) and after deducting estimated expenses and underwriting discounts and commissions payable by us.

We intend to use the net proceeds from this offering primarily for general corporate purposes. Each $1.00 increase or decrease in the assumed initial public offering price of $     per share would cause the net proceeds from this offering, after deducting the underwriting discounts and commissions and estimated offering expenses, received by us to increase or decrease, respectively, by approximately $    , assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same. Each 1,000,000 increase or decrease in the number of shares offered would cause the net proceeds from this offering, after deducting the underwriting discounts and commissions and estimated offering expenses, received by us to increase or decrease, respectively, by approximately     $ million, assuming that the assumed initial public offering price per share for the offering remains at $     (the midpoint of the price range set forth on the cover page of this prospectus).

DIVIDEND POLICY

We do not anticipate declaring or paying any cash dividends to holders of our Class A common stock in the foreseeable future.

DILUTION

Purchasers of our Class A common stock in this offering will experience immediate and substantial dilution in the net tangible book value per share of the Class A common stock for accounting purposes. Our historical net tangible book value as of June 30, 2025 was $291.3 million, or $49.72 per share of our common stock. Our historical net tangible book value represents the amount of our total tangible assets less our total liabilities. Historical net tangible book value per share represents historical net tangible book value divided by 5,859,988 shares of our common stock outstanding as of June 30, 2025. Our as adjusted net tangible book value as of June 30, 2025, was $291.3 million, or $12.62 per share of Class A common stock. As adjusted net tangible book value per share is determined by dividing our as adjusted tangible net worth (tangible assets less total liabilities) by the total number of outstanding shares of Class A common stock that will be outstanding immediately prior to the closing of this offering after giving effect to (i) the Stock Split, (ii) the IPO Recapitalization and (iii) the filing and effectiveness of our Amended and Restated Certificate of Incorporation that will occur after the effectiveness of this registration statement and become effective immediately prior to the completion of this offering. Assuming an initial public offering price of $     per share (the midpoint of the price range set forth on the cover page of this prospectus), after giving effect to the receipt of the estimated net proceeds (after deducting estimated underwriting discounts and commissions and estimated offering expenses), our as further adjusted net tangible book value as of June 30, 2025 would have been approximately $     million, or $     per share. This represents an immediate increase in the as further adjusted net tangible book value of $     per share to our existing stockholders and an immediate dilution (i.e., the difference between the offering price and the as further adjusted net tangible book value after this offering) to new investors purchasing shares of Class A common stock in this offering of $     per share.

Overview

We are redefining the aerospace industry. We have developed an electric aircraft platform and propulsion systems that are positioned to transform the aviation industry forward into a new phase of growth. We design, manufacture and sell high-performance electric aircraft, advanced electric propulsion systems, charging systems and components. Further, we have invested in the underlying infrastructure of this breakthrough technology, which is critical to bringing electric aviation to life. We believe we have developed a differentiated presence in North America and are well positioned to expand globally.

Our company was purpose-built to capture the significant, untapped market opportunity in sustainable, reliable and efficient electric aviation.

Vertical integration allows us to innovate rapidly and capture meaningful economic value throughout an aircraft’s lifetime, by providing batteries and aftermarket services for BETA aircraft and other customers. Our focus is on the Enabling Technologies essential to electric aviation, including batteries, motors, flight control systems and a nationwide network of electric charging and related equipment. With proprietary control over these core technologies, we offer customers a complete platform to support their adoption of electric aircraft to enable both existing and new missions. This multilayered approach provides us with recurring, high margin opportunities.

We are developing highly scalable technologies that can be tailored to and deployed for cost-effective and safe missions across cargo and logistics, medical, defense and passenger end markets. Our simplified approach to designing electric aircraft allows us to service a variety of end markets and mission types leveraging the same core technologies. The portability of our technologies and systems across various aircraft also unlocks flexibility to innovate on future generations of aircraft.

Industry Trends and Outlook

The emergence of electric aviation is ushering in a new era of aviation, with the potential to dramatically lower costs, reduce environmental impact, and open up entirely new markets. By leveraging electric propulsion technologies, aircraft can be made quieter, more efficient, and cheaper to operate than traditional fuel-based models. This shift is especially significant for short-haul and regional routes, where electric aircraft can enable point-to-point travel between smaller cities and underserved areas, bypassing the need for large airport infrastructure. This will be impactful for cargo and logistics, medical, defense, and passenger operations. As battery technology and regulatory frameworks evolve, electric aviation is set to further unlock a wave of innovation, which we believe we are at the forefront of.

Moreover, as global commercial aircraft fleets grow, replacement batteries and maintenance requirements are also expected to grow. These maintenance requirements are recurring and often times non-deferrable, even during periods of economic downturn or reduced demand for commercial air travel. In addition, to support growing fleets of electric aircraft, charging infrastructure will be required at airports and vertiports globally. We primarily compete across four end markets within the aerospace industry: cargo and logistics, medical, defense and passenger.

Cargo and Logistics: We believe cargo and logistics represent near-term, sizable and compelling opportunity for our aircraft and products. Based on the demand for timely supply chain solutions caused by the rise of e-commerce, large global parcel and e-commerce companies have tested and placed orders for electric aircraft and drones to address supply chain constraints. In 2024, e-commerce made up approximately 16% of total retail sales in the United States based on the U.S. Census Bureau, 2024 Annual Retail Trade Survey. In parallel, customers are increasingly demanding faster delivery times, pressuring traditional distribution networks. The introduction of electric aircraft in cargo and logistics, specifically in rural areas, received additional support in the June 2025 Executive Order entitled “Unleashing American Drone Dominance” (the “June 2025 Executive Order”). Customers including UPS and Bristow have placed Firm Orders.

Medical: Electric aviation, both CTOL and VTOL, are well-suited to meet the growing demand for fast, reliable and environmentally sustainable healthcare logistics. Our aircraft are uniquely suited for medical operations with their large and flexible interior spaces. Lower operating costs of electric aircraft make them well-suited for Medical Cargo and Low-Acuity Patient Transfer missions. Customers including United Therapeutics, Metro Aviation and New Zealand Air Ambulance have placed Firm Orders.

Defense: Our ALIA platform is well suited for emerging necessities of modern warfare in both their low maintenance burden and their autonomy-ready designs. Current events and conflicts across the globe have resulted in increased defense and national security spending, both nationally and internationally. Existing defense logistics platforms, mainly helicopters, are poorly suited for imminent threats, including conflicts across wide expanses of ocean. In the United States, defense and national security spending benefits from strong bi-partisan support, which has resulted in a stable and growing investment over time. Our demand forecast consists of nearly 2,000 BETA aircraft for defense applications through 2035 based on DoD estimates and internal opportunity sizing. We believe the increased focus on lower cost, attributable, and, where possible, dual-use technology that can be rapidly produced, will benefit us and aligns with our key focus areas.

Passenger: We believe that the demand for Urban and Regional Air Mobility services will usher in a new wave of growth for the commercial aerospace market. To date, 20% of flights globally are under 300 miles, demonstrating this trend. As traditional, ground-based transportation alternatives become increasingly expensive and population growth accelerates, their scalability is becoming highly questionable. At the same time, technological advances in battery energy density, propulsion, design and materials are enabling aircraft to serve shorter distances in a more cost-effective and environmentally sustainable manner. The convergence of these forces has led airlines, aircraft lessors and charter companies to place orders for over ten thousand aircraft worth over $80 billion. We expect these trends to continue and create new opportunities to convert terrestrial transportation demand to aircraft.

Factors and Trends Affecting Our Business

Development of the Urban and Regional Air Mobility Markets

We expect to derive revenue from the continued development of aerial transportation for cargo and logistics, medical, defense and passenger applications globally. Our CX300 and A250 aircraft are well positioned to serve the urban and regional air mobility markets. While we believe the global market for urban and regional aerial transportation will be large, it remains in the early stages of development and there is no guarantee of future demand.

Government Certification

In the U.S., new aircraft must undergo a rigorous FAA certification process to ensure the design, manufacturing, and individual aircraft meet all applicable safety and airworthiness standards. This begins with Type Certification, in which the FAA evaluates the aircraft design through extensive ground and flight testing to verify compliance with federal regulations. The Type Certification process is conducted in five stages. Each phase is a milestone that addresses product, builds regulatory trust, and unlocks commercial value. Stages one to three can be considered the “definition” phase, while stages four and five are the “implementation” phase. We began working with the FAA in 2020 and have made significant progress toward the certification of both our eCTOL aircraft and our eVTOL aircraft, as well as the certification of our engines for aircraft integration. We expect to be an early manufacturer to achieve Part 23 FAA Type Certification for an electric aircraft, which we believe will allow us to reach a large addressable market of cargo and logistics, medical, defense and passenger operators, while simultaneously building momentum for our VTOL and larger passenger aircraft variants. We target entering FAA-conforming production for our CTOL aircraft at the end of 2026 or early 2027. Our business will require continued focus leading up to certification of our aircraft, including, but not limited to, prototyping and testing, manufacturing, software development, certification, infrastructure and commercialization. If the FAA requires further modifications to our CTOL electric aircraft’s existing certification basis or if there are other regulatory changes or revisions, this could delay our ability to obtain Type Certification for our VTOL aircraft, and could delay our ability to commercialize our aircraft, GSE and enabling technology. We have not yet delivered any certified aircraft, and therefore, no associated revenue has been recognized. See also “Business—Certification.”

We expect the FAA Type Certificate will be reciprocated in certain global markets pursuant to bilateral agreements between the FAA and its counterpart civil aviation authorities. This reciprocal recognition provides the regulatory foundation for civil operation of our aircraft in non-U.S. markets. Following FAA Type Certification, we intend to pursue validation with Transport Canada and the Civil Aviation Authority of New Zealand, in support of firm orders from customers. We have also initiated discussions with EASA regarding validation of H500A and CX300. We anticipate we will start the validation process on H500A with EASA immediately following FAA Type Certification or in 2026, which we believe can position us for efficient international expansion as we develop commercial operations around the world.

In addition to certifying our aircraft, we will also need to obtain authorizations and certifications related to the production of our electric aircraft, GSE and Enabling Technologies. While we expect to meet the applicable requirements, if we fail to obtain any of the required authorizations or certifications, or do so in a timely manner, or if any of these authorizations or certifications are modified, suspended or revoked after we obtain them, we may be unable to launch our commercial electric aviation or do so on the timelines we project, which would have adverse effects on our business, prospects, financial condition or results of operations.

Financing and Commercialization

Since inception, we have made investments across research and development, facilities, equipment, and tooling needed to move toward manufacturing of our aircraft and charging systems. Current and future programs will require significant research and development effort, including extensive testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure. Near-term cash requirements include investing in our manufacturing facilities and equipment, supporting FAA certification, scaled manufacturing operations for commercialization and development and production of aircraft and charging systems. As a result of these anticipated expenditures, we will need additional financing to support our continuing operations and pursue our growth strategy. While we expect that our existing cash and cash equivalents, together with anticipated net proceeds from this offering, will enable us to fund our current and planned operating expenses and capital expenditures for at least the next 12 months, until such time as we generate significant revenue, if ever, we expect to fund our operations through equity offerings or debt financings, credit or loan facilities, potentially other capital resources, or a combination of one or more of these funding sources. There can be no assurances that the Company will be successful in obtaining sufficient funding

##### Table of Contents

on terms acceptable to the Company to fund continuing operations, if at all. Failure to raise capital as and when needed could have a negative impact on our financial condition and ability to pursue our business strategies, and we may be required to delay, reduce or eliminate certain aircraft development programs or other strategic initiatives. See “—Liquidity and capital resources” and “Risk Factors— We have incurred significant losses since inception, we expect to incur losses in the future and we may not be able to achieve or maintain profitability.”

Public Company Costs

We expect to incur incremental, non-recurring costs related to our transition to a publicly traded corporation, including the costs of this initial public offering and the costs associated with the initial implementation of our Sarbanes-Oxley Section 404 internal control implementation and testing. We also expect to incur additional significant and recurring expenses as a publicly traded corporation, including costs associated with the employment of additional personnel, compliance under the Exchange Act, including filing of annual and quarterly reports, registrar and transfer agent fees, national stock exchange fees, audit fees, incremental director and officer liability insurance costs and director and officer compensation.

Components of Results of Operations

We use a variety of financial metrics to assess the performance of our operations, including: revenues; cost of revenues; research and development expenses; and general and administrative expenses.

Revenues

Our product revenue is primarily generated from the sale of tangible products such as GSE and Enabling Technologies, including motors. Our service revenue is primarily generated from engineering, consulting and other service arrangements for our customers. Service revenue also includes revenue associated with usage and priority access from our charge stations.

Costs of Revenues

Cost of product revenues and service revenues may include the direct cost of materials, labor, subcontractors, depreciation, and overhead costs (where allowable) depending on the nature of the agreement. Included within cost of product revenues are purchases made directly for contractual performance obligations primarily recognized over time, and as such no inventories are recorded in the consolidated balance sheet.

Research and Development Expenses

We have invested in research and development for our electric aircraft, electric propulsion systems and charging solutions and network. We have also invested in critical components of our enabling technology including batteries, motors and flight computers. We manage our expenses based on several factors, including industry conditions and expected demand for our services.

Research and development expenses consist primarily of personnel expenses, including salaries, benefits, and stock based compensation, costs of consulting, equipment and materials, temporary tooling, depreciation and amortization associated with long-lived assets, and certain overhead expenses, including rent, information technology costs and utilities. Research and development expenses are partially offset by tax credits for scientific research and development from Revenu Québec, a governmental agency of the Canadian province of Québec, which funds public services using tax monies collected, and payments we receive in the form of government grants.

General and Administrative Expenses

General and administrative expenses consist of personnel expenses, including salaries, benefits, and stock based compensation, related to executive management, finance, legal, and human resource functions and other general corporate expenses, including rent, depreciation and amortization associated with long-lived assets,

85

##### Table of Contents

information technology costs, and utilities. General and administrative expenses are partially offset by payments we received in the form of government grants and other reimbursement agreements, including our agreement with the Advanced Regenerative Manufacturing Institute, Inc. (“ARMI”) in which we are reimbursed for certain expenses incurred.

Interest Expense

Interest expense consists primarily of interest on outstanding long-term debt under our Credit Facility and amortization of the associated deferred financing fees.

Interest Income

Interest income consists of interest earned on cash and cash equivalent balances.

Income Tax Expense

Our provision for income taxes consists of an estimate of federal, state, and foreign income taxes based on enacted federal, state, and foreign tax rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in deferred tax assets and liabilities, and changes in tax law. Due to the level of historical losses, we maintain a valuation allowance against U.S. federal and state deferred tax assets as it has been concluded it is more likely than not that these deferred tax assets will not be realized.

Revenues

Product revenues increased by $1.7 million during the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily attributable to progress towards completion of the FOB of $0.9 million and $0.7 million related to a new contract with a commercial customer to deliver electric propulsion motors.

Service revenues decreased by $1.9 million, or 12.6%, during the year ended December 31, 2024 compared to the year ended December 31, 2023. The decrease was primarily attributable to a reduction in service revenue recognized from certain U.S. government customers of $3.1 million resulting from the timing of deliverables and reduction in contracted services during 2024, partially offset by an increase of $1.2 million from commercial customers related to engineering and consulting services to support our customers’ research and development activities as well as priority access to our charging stations.

Cost of Revenues

Cost of product revenues increased by $1.3 million during the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily attributable to an increase in labor and material costs to construct the FOB of $0.9 million and costs associated with new contracts with commercial customers of $0.4 million.

Cost of service revenues increased by $1.2 million, or 65.5%, during the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily attributable to an increase in labor and material costs to fulfill trade study and service agreements with the U.S. government of $0.7 million and commercial customers of $0.5 million.

Gross Margin

Product revenue gross margin increased by $0.3 million during the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was attributable to increased product revenues of $1.6 million, partially offset by an increase in cost of product revenues of $1.3 million as described above. Product revenue gross margin as a percentage of product revenue increased year-over-year due to a more favorable mix of customer contracts.

Service revenue gross margin decreased by $3.1 million, or 23.3%, during the year ended December 31, 2024 compared to the year ended December 31, 2023. The decrease was attributable to decreased service revenues of $1.9 million and increased cost of service revenues of $1.2 million. Service revenue gross margin as a percentage of service revenue decreased year over year due to a less favorable mix of customer contracts.

Research and Development Expenses

Research and development expenses increased $68.6 million, or 49.6%, for the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily attributable to continued spend related to the development, testing, certification, and prototype production of our electric aircraft. As part of these efforts, we incurred increased expenses for parts and materials of $31.9 million, labor costs including stock based compensation of $16.7 million, depreciation and amortization of $6.5 million resulting from our investment in our production facility, consulting and professional fees of $5.3 million, software of $2.6 million, tooling of $2.0 million, and other expenses of $3.6 million.

General and Administrative Expenses

General and administrative expenses increased $14.2 million, or 23.1%, for the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily attributable to the growth of our business operations, including an increase in labor costs and stock based compensation expense totaling $15.2 million and $4.2 million of other administrative costs. This increase was partially offset by a reduction in consulting and professional services of $3.3 million primarily due to shifting internal legal costs and an increase in receipt of certain governmental grants and reimbursement agreements, such as our agreement with ARMI of $1.9 million.

Interest Expense

Interest expense increased $11.1 million for the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily attributable to the timing of the initial borrowings under our Credit Facility occurring in the fourth quarter of the year ended December 31, 2023 and an increase in borrowings during the year ended December 31, 2024.

##### Table of Contents

Interest Income

Interest income decreased $3.9 million, or 31.3%, for the year ended December 31, 2024 compared to the year ended December 31, 2023. The decrease was primarily due to market fluctuation and the associated decrease in interest earned, given our lower average cash and cash equivalent balances held in interest-earning accounts, comparatively.

Income Tax Expense

Income tax expense decreased $0.5 million, or 50.1%, for the year ended December 31, 2024 compared to the year ended December 31, 2023, primarily due to recognition of return-to-provision adjustments related to foreign research and development credits.

Liquidity and Capital Resources

We have incurred net losses and negative operating cash flows from operations since we were formed and began designing our electric aircraft in 2018, and we expect to continue to incur losses and negative operating cash flows for the foreseeable future until we successfully commence sustainable commercial operations. Historically, our primary sources of liquidity have been borrowings under our Credit Facility, equity financings, government funding and consideration from contracts with customers. To date, our primary use of capital has been for contractual obligations and the development of our electric aircraft, GSE and Enabling Technologies.

As of June 30, 2025, we had cash and cash equivalents of $174.5 million. Until we generate sufficient operating cash flow to fully cover our operating expenses, working capital needs and planned capital expenditures, or if circumstances evolve differently than anticipated, we expect to utilize a combination of equity and debt financings to fund any future remaining capital needs. If we raise funds by issuing equity securities, dilution to stockholders may result. Any equity securities issued may also provide for rights, preferences, or privileges senior to those of holders of Common Stock. If we raise funds by issuing debt securities, these debt securities may have rights, preferences, and privileges senior to those of preferred and common stockholders. The terms of debt securities or borrowings could impose significant restrictions on our operations. The capital markets have in the past, and may in the future, experience periods of volatility that could impact the availability and cost of equity and debt financing. We can give no assurances that we will be able to secure such additional sources of funds to support our operations, or, if such funds are available to us, that such additional financing will be sufficient to meet our needs. See Note 1 to the Company’s interim unaudited condensed consolidated financial statements, annual audited consolidated financial statements and “Risk factors—Our business plan requires a significant amount of capital. We expect to require additional future funding to support our operations and implementation of our growth plans and we may be unable to access the capital and credit markets or borrow on affordable terms to obtain additional capital that we may require.”

Our principal uses of cash in recent periods were to fund our research and development activities, personnel cost and support services, including our battery, motor and charging services. Near-term cash requirements will also include spending on research and development of emerging technologies, strategic growth initiatives, including obtaining certifications and manufacturing our aircraft, commercial and go-to market infrastructure. We do not have material cash requirements related to current contractual obligations. As such, our cash requirements are highly dependent upon management’s decisions about the pace and focus of both our short and long-term spending.

Cash requirements can fluctuate based on business decisions that could accelerate or defer spending, including the timing or pace of certification, investments, infrastructure and production of electric aircraft, GSE and Enabling Technologies. Our future capital requirements will depend on many factors, including our revenue growth rate, the timing and the amount of cash or grants received from our customers or governmental entities, respectively, the expansion of sales and marketing activities, and the timing and extent of spending to support development efforts.

Operating Activities

We continue to experience negative cash flows from operations as we develop our electric aircraft, GSE and Enabling Technologies and prepare for the future commercialization of our products and services. Our cash flows from operating activities are significantly affected by our expenditures in research and development and overhead manufacturing related to the scaling of our operations. Our operating cash flows are also affected by our working capital needs to support growth, personnel related expenditures, accounts payable and other current assets and liabilities.

For the six months ended June 30, 2025, net cash used in operating activities was $114.5 million, primarily due to a net loss of $158.7 million, offset by non-cash charges including $10.5 million related to depreciation and amortization, $11.6 million related to stock based compensation, and $3.2 million of other non-cash charges, partially offset by $18.9 million of cash provided by changes in operating assets and liabilities. For the six months ended June 30, 2025, cash provided by changes in operating assets and liabilities of $18.9 million was primarily attributable to an increase in accounts payable, accrued expenses and current liabilities of $13.5 million, a decrease in prepaid expenses and other current assets of $4.5 million, and an increase in deferred revenue of $2.8 million, partially offset by an increase in accounts receivable of $1.5 million and a decrease in operating lease liabilities of $0.4 million.

For the six months ended June 30, 2024, net cash used in operating activities was $101.6 million, primarily due to a net loss of $124.1 million, partially offset by non-cash charges including $7.4 million related to depreciation and amortization, $4.6 million related to stock based compensation, and $1.5 million of other non-cash charges. For the six months ended June 30, 2024, net cash provided by changes in operating assets and liabilities of $9.0 million was primarily attributable to an increase in accounts payable, accrued expenses and current liabilities of $7.6 million and a decreases in prepaid expenses and other current assets of $1.6 million and operating lease liabilities of $0.2 million.

For the year ended December 31, 2024, net cash used in operating activities was $222.7 million, primarily due to a net loss of $275.6 million, offset by non-cash charges including $16.5 million related to depreciation and

amortization, $12.1 million related to stock based compensation, and $3.1 million of other non-cash charges, partially offset by $21.3 million of cash provided by changes in operating assets and liabilities. For the year ended December 31, 2024, cash provided by changes in operating assets and liabilities of $21.3 million was primarily attributable to an increase in deferred revenue of $8.6 million, an increase in accounts payable, accrued expenses and current liabilities of $6.2 million, and a decrease in prepaid expenses and other current assets of $4.4 million, which were generally driven by the growth in our business and the advancement of our research and development efforts.

For the year ended December 31, 2023, net cash used in operating activities was $158.0 million, primarily due to a net loss of $175.6 million, partially offset by non-cash charges including $8.6 million related to depreciation and amortization and $9.0 million related to stock based compensation. For the year ended December 31, 2023, net cash used by changes in operating assets and liabilities of $2.1 million was primarily attributable to an increase in prepaid expenses and other current assets of $9.8 million, partially offset by an increase in accounts payable, accrued expenses, and current liabilities of $5.7 million and a decrease in contract assets of $2.3 million which were generally driven by the growth in our business and the advancement of our research and development efforts.

Investing Activities

We continue to experience negative cash flows from investing activities as we build our infrastructure and purchase equipment to support the development and commercialization of our electric aircraft and charging network. Cash flows used in investing activities primarily relate to capital expenditures to support our growth in operations, including expenditures related to the construction and expansion of our charging and production facilities, acquisitions of machinery and equipment, tooling and technology infrastructure, partially offset by proceeds from sales of property and equipment, customer funding from GSE installation and governmental grants.

For the six months ended June 30, 2025, net cash used in investing activities was $11.8 million, primarily due to net purchases of property and equipment of $12.7 million, partially offset by proceeds from the sale of property and equipment of $0.9 million.

For the six months ended June 30, 2024, net cash used in investing activities was $38.3 million, primarily due to net purchases of property and equipment of $38.6 million, partially offset by proceeds from the sale of property and equipment of $0.4 million.

For the year ended December 31, 2024, net cash used in investing activities was $68.8 million, primarily due to net purchases of property and equipment of $73.5 million, partially offset by proceeds from the sale of property and equipment of $4.7 million.

For the year ended December 31, 2023, net cash used in investing activities was $152.3 million, primarily due to construction of our production facility and investment in production related tooling.

Financing Activities

For the six months ended June 30, 2025, net cash provided by financing activities was $2.3 million, primarily due to the proceeds received from issuances of our Series C Preferred Stock of $3.0 million and the proceeds received from the issuance of common stock of $1.2 million, partially offset by stock issuance costs of $1.7 million and the repayment of debt of $0.2 million.

For the six months ended June 30, 2024, net cash provided by financing activities was $14.2 million, primarily due to the proceeds from the issuance of our promissory note of $14.4 million, and the issuance of common stock of $1.0 million, partially offset by the repurchase of common stock and repayment of debt and debt issuance costs of $1.2 million.

##### Table of Contents

For the year ended December 31, 2024, net cash provided by financing activities was $339.3 million, primarily due to the proceeds received from issuances of our Series C Preferred Stock of $324.0 million and the proceeds received from the issuance of our promissory note of $15.5 million.

For the year ended December 31, 2023, net cash provided by financing activities was $134.3 million, primarily due to the proceeds from the issuance of our promissory note of $135.7 million, and the issuance of Common Stock of $0.7 million, partially offset by the repayment of debt and debt issuance costs of $2.1 million.

Credit Facility

On December 13, 2023, we entered into our Credit Facility, which provided commitments in an aggregate amount equal to $170.1 million to, among other things, finance certain of our goods and services costs related to the design, planning, permitting, and construction of the Final Assembly Facility. Our Credit Facility matures on December 20, 2038. As of June 30, 2025, we have fully drawn down the Credit Facility in an aggregate principal amount equal to $151.2 million, net of exposure fees of $18.9 million.

The Company’s obligations under the Credit Agreement are secured by the “Collateral” (as defined in the Credit Agreement), which generally consists of the Final Assembly Facility.

The Company is no longer able to draw down further funds under our Credit Facility given that each of (a) the commitment availability period for drawing funds thereunder has expired in accordance with its terms and (b) the commitments under our Credit Facility have been fully drawn.

Each disbursement under our Credit Facility accrues interest at a fixed interest rate of 5.52% per annum, which per annum interest rate is subject to increase in accordance with the terms of the Credit Agreement upon the occurrence of a “Payment Default” and/or a “Trigger Event” (each such term as defined in the Credit Agreement). Inclusive of the timing of drawdowns, exposure fees, and debt issuance costs, the effective per annum interest rate on outstanding borrowings under our Credit Facility was 7.32%. Interest under our Credit Facility is payable quarterly in arrears on each March 20, June 20, September 20, and December 20 of each year.

The Company may, from time to time, prepay all or any part of the outstanding principal balance of the disbursements made pursuant to our Credit Facility, subject to a prepayment premium in an amount equal to: the amount by which (a) the amount of the prepaid principal is less than (b) the sum of the present values, discounted in accordance with the terms of the Credit Agreement, of (x) the installments of principal being prepaid, plus (y) the amounts of interest which would otherwise have accrued on such principal to the remaining interest payment dates.

The Credit Agreement provides for mandatory amortization payments with respect to the principal amount of funds disbursed pursuant to our Credit Facility, in the amounts and on the terms set forth in the Credit Agreement, such that such principal amount is repaid in fifty-four (54) succussive quarterly installments. Such amortization payments are required to be made by the Company on each March 20, June 20, September 20, and December 20 of each year, commencing on September 20, 2025. Furthermore, the Credit Agreement includes mandatory prepayments in connection with certain sanctions-related events, events of loss, and collateral destruction events.

Our Credit Facility documents contain affirmative and negative covenants, including among other things, delivery of annual audited financial statements and Make More in America Initiative annual reports, maintenance of certain governmental consents, licenses, permits, authorizations, and approvals, compliance with laws (including sanctions) and the “MMIA Compliance Plan” (as defined in the Credit Agreement), and maintenance of insurance, along with restrictions on the incurrence of liens, asset dispositions, changes in nature of business, mergers, consolidations, dissolutions, and sales, and other customary covenants, in each case, subject to customary exceptions. The Credit Agreement also includes events of default relating to customary matters (and customary notice and cure periods), including, among other things, nonpayment of principal, interest, or other amounts,

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with GAAP. In connection with preparing our consolidated financial statements and interim condensed consolidated financial statements, we are required to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue, expense and the related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends and other factors that management believes to be relevant at the time we prepare our consolidated financial statements. On a regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ materially from our assumptions and estimates.

Our significant accounting policies are discussed in Note 2, “Basis of Presentation and Accounting Policies” in the Notes to our annual consolidated financial statements included elsewhere in this prospectus. Management believes that the following accounting policies are critical to fully understanding and evaluating our reported financial results, and they require management to make estimates about the effect of matters that are inherently uncertain.

Stock Based Compensation

We measure all stock options and other stock based awards granted to employees, non-employees, and directors based on the fair value on the date of the grant. We recognize compensation expense over the requisite service period, which is generally the vesting period of the respective award. We generally issue stock options with only service-based vesting conditions and record the expense for such awards using the straight-line accounting method. We recognize forfeitures at the time forfeitures occur.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model, which requires inputs based on certain subjective assumptions. These assumptions include:

| • |  | Fair value of Common Stock – see discussion below for our determination of the fair value of our Common Stock.

95

##### Table of Contents

| • |  | Expected volatility – We estimate our expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expect to continue to do so until we have adequate historical data regarding the volatility of our own traded stock price.

| • |  | Expected term – The expected term of our stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The expected term of stock options is equal to the weighted average vesting term plus the contractual term divided by two.

| • |  | Risk-free interest rate – The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award.

| • |  | Expected dividend yield – The expected dividend yield is zero because we have never paid cash dividends on Common Stock and do not expect to pay any cash dividends in the foreseeable future.

As a privately held company, there has been no public market for our Common Stock to date. The estimated fair value of our Common Stock has been determined by our Board as of the date of each option grant, with input from management, considering the most recently available third-party valuations of our Common Stock and our Boards’ assessment of additional objective and subjective factors that it believed were relevant and which may have changed from the date of the most recent valuation through the date of the grant. These third-party valuations were performed in accordance with the guidance outlined in the American Institute of Certified Public Accountants’ Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation.

Our third-party valuations of Common Stock were prepared using the option-pricing method (“OPM”) or the hybrid method, both of which used a market approach to estimate our enterprise value. The October 2024 third-party valuation was prepared using the hybrid method, whereas all prior third-party valuations were prepared using the OPM. The OPM treats common stock and preferred stock as call options on the total equity value of a company, with exercise prices based on the value thresholds at which the allocation among the various holders of a company’s securities changes. Under this method, the common stock has value only if the funds available for distribution to stockholders exceeded the value of the preferred stock liquidation preferences at the time of the liquidity event, such as a strategic sale or a merger. The hybrid method is a probability-weighted expected return method (“PWERM”) where the equity value in one or more of the scenarios is calculated using an OPM. The PWERM is a scenario-based methodology that estimates the fair value of common stock based upon an analysis of future values for us, assuming various outcomes. The common stock value is based on the probability-weighted present value of expected future investment returns considering each of the possible outcomes available as well as the rights of each class of stock. The future value of the common stock under each outcome is discounted back to the valuation date at an appropriate risk-adjusted discount rate and probability weighted to arrive at an indication of value for the common stock. A discount for lack of marketability of the common stock is then applied to arrive at an indication of value for the common stock.

In addition to considering the results of these third-party valuations, our Board considered various objective and subjective factors to determine the fair value of our Common Stock as of each grant date, including:

| • |  | the prices at which we sold shares of Preferred Stock and the superior rights and preferences of the Preferred Stock relative to our Common Stock at the time of each grant;

| • |  | the lack of an active public market, for our Common Stock and Preferred Stock;

| • |  | the progress of our research and development efforts;

| • |  | our stage of development and commercialization and our business strategy, and material risks to our business;

| • |  | external market conditions affecting the aviation industry;

96

##### Table of Contents

| • |  | our financial position, including cash on hand, and our historical and forecasted performance and operating results;

| • |  | the likelihood of achieving a liquidity event, such as an initial public offering or sale of our company in light of prevailing market conditions; and

| • |  | the analysis of initial public offerings and the market performance of similar companies in the aviation industry.

Following the IPO Recapitalization and once a public trading market for our Class A common stock has been established in connection with the completion of this offering, it will no longer be necessary for our Board to estimate the fair value of our Class A common stock in connection with our accounting for stock options and other such awards we may grant, as the fair value of our Class A common stock will be determined based on the quoted market price of our Class A common stock.

The following table summarizes by grant date the number of shares subject to options granted between January 1, 2023 and July 31, 2025, the per share exercise price of the options, the per share fair value of Common Stock underlying the options on each grant date, and the per share estimated fair value of the options:

Recently Issued Accounting Pronouncements

See Note 2 “Basis of Presentation and Accounting Policies” in the Notes to our audited historical consolidated financial statements and interim condensed consolidated financial statements included elsewhere in this prospectus, for a discussion of recent accounting pronouncements.

Emerging Growth Company Status

Under the JOBS Act, we expect that we will meet the definition of an “emerging growth company,” which would allow us to have an extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of the extended transition period to comply with new or revised accounting standards. Electing to use the phase-in periods permitted by this election may make it difficult to compare our financial statements to those of non-emerging growth companies and other emerging growth companies that have opted out of the longer phase-in periods under Section 107 of the JOBS Act and who will comply with new or revised financial accounting standards.

We will remain an emerging growth company until the earliest of (i) the last day of our first fiscal year in which we have total annual gross revenues of $1.235 billion or more, (ii) the last day of the first fiscal year in

which we become a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, with at least $700 million of equity securities held by non-affiliates as of the end of the last business day of the second quarter of that fiscal year, (iii) the date on which we have issued, in any three-year period, more than $1.0 billion in non-convertible debt securities, or (iv) the last day of our fiscal year after the fifth anniversary of the date of the completion of this offering.

Quantitative and Qualitative Disclosure about Market Risks

Market risk is the risk of loss arising from adverse changes in market rates and prices. Currently, our market risks relate to potential changes in the fair value of our long-term debt due to fluctuations in applicable market interest rates. Going forward our market risk exposure generally will be limited to those risks that arise in the normal course of business, as we do not engage in speculative, non-operating transactions, nor do we utilize financial instruments or derivative instruments for trading purposes.

Interest Rate Risk

We had cash and cash equivalents totaling $174.5 million as of June 30, 2025. These amounts were invested in standard checking, demand deposit and money market funds. The cash and cash equivalents are held for working capital purposes. We do not enter into investments for trading or speculative purposes. We believe that we do not have any material exposure to changes in the fair value as a result of changes in interest rates due to the short term nature of our cash equivalents. Declines in interest rates, however, would reduce future interest income.

Credit Risk

Financial instruments that subject us to significant concentrations of credit risk consist primarily of cash and money-market cash equivalents. Our cash is held in accounts with multiple financial institutions that we believe are creditworthy. These amounts at times may exceed federally insured limits. We have not experienced any credit losses in such accounts and do not believe it is exposed to any significant credit risk on these funds.

Off-Balance Sheet Arrangements

We have no material off-balance sheet arrangements.

FOUNDER’S LETTER

Potential Investors and Aviators, “For once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return,” - attributed to Leonardo di Vinci… and I would add, “and bring someone with you.” I have been thinking about BETA for more than 25 years, going all the way back to my college thesis “BETA Air.” For me, flying is the ultimate freedom. Something I love to share. BETA combines my love for aviation and the mastery that flying demands with my lifelong pursuits of building and engineering. |  |

BETA is the embodiment of an unrelenting passion and mission. The technical art of designing, building and testing flying machines is an unforgiving pursuit of excellence that requires a multidisciplinary understanding of the physics of flight and psychology of how people relate to machines. The challenges are real, the opportunity is huge, and a group of passionate aviators are redefining how we use the z-dimension of our world. Now, launching BETA as a public company, I look forward to sharing with you the awesome potential electrifying aviation has in transforming an industry and aspects of the economy and society.

Electric aviation is inevitable. We believe it will lower the cost of flight, improve safety, expand aviation’s utility, and do so in balance with our environment. Electric aviation will drastically expand the number of flights by opening up new routes and feasible missions allowing cargo and people to fly more. BETA is starting this inevitable transition with our ALIA aircraft platform utilizing the proprietary core technologies we have designed and developed. The deployment of our technology through aircraft sales enables an exciting business proposition with resilient and recurring revenues through aftermarket sales for multiple decades, particularly with our proprietary batteries. The ALIA platform and the core technology we have developed only represent the starting point of our ambitions. I believe the benefits of our core technologies will prove to be disruptive. Advancements in our technologies can make increasingly larger passenger (19, 70, 250 seats) and cargo electric aircraft possible.

Engineering the future of aviation is a technologically unforgiving pursuit. Our standards are high. It is challenging and demanding, but the outcome is rewarding. Our company is rooted in first-principals engineering, where we design and build each component using the fundamental laws of physics. We fly what we build, we do more than we say and we respect the fact that we are in a highly regulated industry where safety is paramount. BETA’s foundation is in the design and engineering of the highly reliable and safe enabling technologies: motors, inverters, batteries, flight controls and a nationwide electric charging network.

“Perfection is achieved not when there is nothing left to add, but when there is nothing left to take away.”— Antoine de Saint-Exupéry. This quote welcomes people into our R&D facility. If airplanes don’t fly, they aren’t really airplanes. What most often keeps aircraft grounded are equipment failures due to unnecessarily complex design and weather. This compelled us to focus on simplicity and to question the need for complex tilting rotors (thrust vectoring), water pumps, variable pitch propellers, collectives, gear reductions, and state changes in software. These are all absent from our simple aircraft design, and as a result are absent from our certification requirements with the FAA and our bill of materials.

Our focus is on making a lightweight aircraft with low aerodynamic drag, designed to carry a high energy- density battery, and converting that precious energy into propulsion in the most efficient way possible. Our back-to-basics approach is working. Our longest electric airplane flight is 336 NM. We completed the first ever full-scale manned eVTOL transition. Our electric airplanes have been flying military and FAA piloted missions for several years, including by pilots from the FAA and U.S. military starting in 2022, and are currently flying on multiple continents.

I challenge you to find another electric aerospace company doing more piloted flying than BETA. Every employee at BETA has access to our flight school. Flying creates an extremely close connection to what is important in aircraft design, along with production, sales and support. Aviators understand weather, instrument conditions, reserves, dispatch rates and failures. Aviators understand that the FAA does not give credit for merely making something work. The FAA gives you credit when you show that something doesn’t fail, and, if it does, it fails in a safe way. Design simplicity fits well with this FAA regulatory fact, and our aircraft embody the knowledge we gain by flying.

Vertical integration is at the core of our manufacturing philosophy. We design and make our own motors, inverters, battery packs, monitoring systems, computers, and the equipment used to build our charging network. The ability to move fast as we build an electric aviation ecosystem is a key competitive advantage. The early look at the potential benefits of this strategy is illustrated by the fact that today, we own the charging infrastructure at airports around the country and are supplying our core products to others in the budding electric aerospace industry.

BETA also differentiates itself from the competition by doing significantly more with less. Simplicity is again the key. We have built a nationwide charging network, launched multiple products, shown up for the military, flown our aircraft across the U.S. and Europe and demonstrated the most technically challenging corners of electric aviation. I’m proud of the respect we have earned by being humble, effective and honest. I have learned this from John Abele, Martine Rothblatt, Dean Kamen, Chuck Davis and my parents. I feel extremely lucky to be surrounded by capable, dedicated and hard-working mentors and colleagues.

I invite you to evaluate us for yourself; visit us, fly with us, get to know the team, and ultimately judge us on the exceptional products we have created. We are here because we love what we do. You will feel it. I look forward to getting to know you and welcoming you on this adventure as we build the future of aviation.

BUSINESS

Our Company

We are redefining the aerospace industry. We have developed an electric aircraft platform and propulsion systems that are positioned to transform the aviation industry forward into a new phase of growth. We design, manufacture and sell high-performance electric aircraft, advanced electric propulsion systems, charging systems and components. Further, we have invested in the underlying infrastructure of this breakthrough technology, which is critical to bringing electric aviation to life. We believe we have developed a differentiated presence in North America and are well positioned to expand globally.

Our company was purpose-built to capture the significant, untapped market opportunity in sustainable, reliable and efficient electric aviation.

Vertical integration allows us to innovate rapidly and capture meaningful economic value throughout an aircraft’s lifetime by providing batteries and aftermarket services for BETA aircraft and other customers. Our focus is on the Enabling Technologies essential to electric aviation, including batteries, motors, flight control systems and a nationwide network of electric charging and related equipment. With proprietary control over these core technologies, we offer customers a complete platform to support their adoption of electric aircraft to enable both existing and new missions. This multilayered approach provides us with recurring, high margin opportunities.

We have developed highly scalable technologies that can be tailored to, and deployed for cost-effective and safe missions across cargo and logistics, defense, passenger and medical end markets. Our simplified approach to designing electric aircraft allows us to service a variety of end markets and mission types leveraging the same core technologies. The portability of our technologies and systems across various aircraft also unlocks flexibility to innovate on future generations of aircraft.

We are pursuing a stepwise approach to growing our business in both certification and market entry. We believe this significantly derisks our business model and expands our addressable market. This approach creates a logical progression where each certification effort informs the next—streamlining documentation, building continuity with FAA personnel, and reducing risk across programs.

Our go-to-market strategy is also incremental over time. We intend to prioritize cargo and logistics, while also giving focus to military applications and medical industries, before delivering aircraft to passenger operators.

We believe our CX300 electric aircraft is at the forefront of the electric aviation industry. The ALIA CTOL has successfully flown thousands of flights, over 80,000 miles, including operations in North America and Europe. This includes the world’s first, all-electric passenger flights into John F. Kennedy International Airport, which utilized approximately $7.00 in flight fuel costs, demonstrating electric aircraft’s integration into congested national airspace and approximately 95% in fuel cost savings when compared to a combustion aircraft based on internal estimates. Our CX300 also made its debut at the Paris Air Show in June 2025 opening the show with an aerial ballet demonstrating the performance and agility of our electric aircraft. Further, our aircraft has been used by the U.S. military in training missions and flown by the FAA, providing us with valuable data with respect to our aircraft and our certification strategy. We have also completed successful missions with the DoD and cargo and logistics and medical partners and customers such as UPS and United Therapeutics.

We believe our aircraft represents a significant cost efficiency advantage, as total operating costs are 42% lower compared to new traditional conventional aircraft based on internal estimates. This reduction is primarily attributed to the substantially reduced maintenance requirements given our simplified aircraft design. Our

101

##### Table of Contents

aircraft’s design eliminates the need for complex components such as gear boxes, in-flight liquid cooling systems, and thrust vectoring mechanisms, further streamlining maintenance operations and contributing to lower operational costs. We believe the operating savings are even higher when comparing our eVTOL variant relative to traditional helicopters.

We believe we are the first electric aircraft OEM with a scale production facility, and we have room to grow. Our approximately 188,000 square foot Vermont production facility is designed to support production of more than 300 aircraft annually at maturity through optimized processes and manufacturing flows. We have site control and permits for expansion to over 355,000 square feet to accommodate significant future growth.

Key and Enabling Technologies employed on the BETA Aircraft.

Our Business Model

Our business model contemplates four key revenue streams:

(1) | selling aircraft to military and commercial customers such as UPS, Air New Zealand and United Therapeutics;

(2) | selling replacement batteries to operators in the aftermarket;

(3) | selling propulsion systems as a merchant supplier to other eVTOL manufacturers such as Textron eAviation; and

(4) | selling GSE, primarily chargers, to state governments, operators, Fixed Base Operators and other electric aviation companies.

Our market-entry strategy for our aircraft is initially focused on selling to operators that specialize in cargo and logistics, military and medical operations, before expanding into delivery of aircraft to customers for passenger operations. That said, our financial opportunity is maximized over the entire lifetime of the aircraft. For example, if operated for 20 years, we estimate a typical electric aircraft will require 18 to 20 sets of replacement batteries, generating approximately $13 million in revenue assuming replacement of batteries for all customer use cases every year at current year pricing levels with a 2.5% annual escalation. We believe there are customers who will easily meet this utilization.

Further, our customers will also benefit from improving battery technology over the lifetime of the aircraft, as replacement batteries are expected to deliver superior aircraft performance due to improved energy density, which directly translates into longer range and higher speeds. We believe our ownership of the battery pack technology, protected by an extensive portfolio of intellectual property, will allow us to recognize substantial recurring revenue, even after the initial aircraft sale, contributing a majority of the lifetime revenue at attractive margins.

As a merchant supplier, we leverage our technical advantage in selling propulsion systems, core components and charging infrastructure to others in the aerospace and marine industries.

We are also developing a fully-integrated, digital platform, “Operate,” with access to real-time data from our aircraft and GSE to optimize our customers’ operational capabilities. This system enables end-to-end visibility and control over their electric aircraft fleets, including real-time flight monitoring and charging infrastructure management, AI-powered predictive maintenance and network planning, and battery health and

103

##### Table of Contents

operating cost optimization. Our digital platform also drives regulatory compliance through automated maintenance record synchronization and offers seamless integration with existing aviation systems through universal API access.

We are developing Operate in four modules: Maintenance, Control Center, Network and Data. The Maintenance module launched in July 2025 and is in active use to track maintenance on the four aircraft currently in the field, with Bristow and Air New Zealand expected to use it during operational trials. Development of the integrated Control Center module is underway, with limited functionality already in use, and an initial commercially viable version targeted by the first half of 2026. The Network and Data modules remain in planning, with availability expected prior to aircraft certification, currently targeted for late 2026.

Finally, our business model capitalizes on a fundamental element of electric mobility. Electric aircraft need electric charging. To this end, we have developed a series of charging infrastructure, including large charge cubes designed for stationary charging, mini cubes designed for more mobile applications and thermal management systems, which cool batteries during high-speed charging. Our charging products and infrastructure are designed to use the CCS-1 charging protocol, allowing for charging access for both electric aircraft and ground vehicles. Through a series of customer and government investments, we have built a charging infrastructure for all electric aircraft operators to use nationwide.

Our Products

We develop electric aircraft, their critical systems and components (such as motors and batteries) and GSE to charge them. We believe this enables our customers to complete all-electric, cargo and logistics, medical transport, and passenger missions at lower operating costs.

Aircraft

ALIA CTOL CX300 (Piloted, Electric)

ALIA CTOL (CX300) – Designed for all-weather deployment and reliability, our CTOL aircraft transports six people or 200 cubic feet of cargo plus two crew members on missions of up to approximately 215 nautical miles. This aircraft is intended to leverage existing airport infrastructure and fly in accordance with existing procedures to enable rapid adoption. We are targeting FAA Part 23 certification at the end of 2026 or early 2027. Our Backlog for

104

##### Table of Contents

the CTOL consists of 331 units, of which 131 units are for Firm Orders and 200 units are for Options. Examples of key CTOL launch customers include Air New Zealand and United Therapeutics, highlighting the versatility of the aircraft. We have not yet delivered any certified aircraft, and therefore, no associated revenue has been recognized.

ALIA VTOL A250 (Piloted, Electric)

ALIA VTOL (A250)– The ALIA VTOL (A250) is a vertical takeoff and landing aircraft, allowing it to operate from locations with or without runway access. We believe our simple and efficient design differentiates us from others in the industry – enabling a clear path to certification, lower operating costs, high reliability and class-leading range and payload.

Our Backlog for the ALIA VTOL consists of 560 units, of which 158 units are for Firm Orders and 402 units are for Options, with a goal of achieving Type Certification towards the end of 2027 or early 2028. Our order book highlights the broad capabilities of our aircraft across: cargo and logistics, including orders from UPS and Bristow; medical operations, including orders from Metro Aviation and New Zealand Air Ambulance; and passenger operations, including orders from Blade and FlyNYON. We have not yet delivered any certified aircraft, and therefore, no associated revenue has been recognized.

ALIA Defense VTOL MV250 (Autonomous, Hybrid)

ALIA Defense VTOL (MV250) – The MV250 is the military variant of our VTOL aircraft and draws heavily from the ALIA platform. The capability specifications from our cargo and logistics customers stack up

105

##### Table of Contents

closely with specifications from the U.S. military for their next generation aircraft, including capabilities such as long range, low heat/noise signature operations and the potential to operate autonomously. The specifications from these customers, which we expect to be able to deliver, are for a vertical takeoff and landing aircraft that can carry up to one ton (approximately 2,000 pounds) 250 nautical miles, which is priced between $5-10 million, and has operating cost benefits over existing aircraft models.

We expect multiple military branches to use ALIA defense VTOLs in their operations. We remain a candidate for the USMC’s Aerial Logistic Connector program which seeks to fill the large size class contested logistics. Additionally, the Army established the Contested Logistics Cross-Functional Team under Army Futures Command to generate requirements that will drive future programs of record.

We are also partnering with GE Aerospace to co-develop a hybrid electric turbogenerator, specifically designed for defense and civil applications. In conjunction with the partnership, GE Aerospace is making an equity investment of $300 million in BETA. This collaboration is poised to enhance our offerings by integrating hybrid electric capabilities, which are critical to modern defense applications. The new turbogenerator technology, we believe, can deliver multiple advantages, including longer range, higher speed, reduced operating costs, and increased payload capacity. Our joint efforts signify a strategic advancement in leveraging hybrid electric propulsion systems, meeting the stringent demands of both defense operations and commercial aviation. This partnership reflects our commitment to adopting cutting-edge technology for sustained growth and operational efficiency.

The certification process for defense aircraft is different from the FAA civil aircraft certification process in that standards of safety and performance are applied to aircraft based on the intended mission and level of safety required to perform the intended mission for the DoD; in many cases offering reduced requirements than the FAA. Due to the variety of mission cases the MV250 has the potential to serve, the requirements for and timeframe in which it is approved for military service remains to be defined. Separately, the DoD has the ability to operate the aircraft for a subset of test and demonstration missions prior to obtaining formal approval.

Larger Aircraft – We are in the development phase of a larger aircraft initially designed to carry up to 19 passengers. We are able to move rapidly by leveraging our existing technologies and experience from existing aircraft. We believe this product will further expand our market share by creating new opportunities for operators to realize the benefits of electric aviation in large aircraft. The timeline for obtaining civil certification of the larger commercial airplane has yet to be determined.

Motors

H500A Motor (L) and V600 Motor (R)

The H500A motor leads the industry both in terms of maximum power output and power-to-weight ratio, weighing only 165 pounds while providing 573 horsepower based on internal testing. We believe this leadership position is achieved through a simple design that is free of heavy liquid cooling systems and complicated assemblies – allowing for 97.5% efficiency based on internal testing. The H500A features dual redundancy and significantly fewer parts than a comparable legacy aircraft engine. Our design philosophy of the H500A lends itself to easy adaptation into the more powerful H500B variant and V600A vertical lift motor, both currently in development.

We sell our motors to both established aerospace and defense OEMs, as well as new market entrants designing electric aircraft. Our electric motors have aerospace and marine applications that require high reliability with significant power in a small package. As an example, we have a subcontract with General Dynamics Applied Physical Sciences, manufacturing and delivering hardware and associated engineering services, in support of a DARPA program focused on developing advanced propulsion technology for undersea vehicles. These opportunities represent both initial sales and long-term recurring revenue when motors require maintenance or replacement in the aftermarket.

In July 2025, the Hartzell Propeller received FAA Part 35 Type Certification, becoming the first propeller the FAA has certified for any electric aircraft. This milestone serves as a stepping stone for obtaining Type Certification by the FAA for the H500A under Part 33 given the parallels between FAA Part 35 Type Certification, which governs propeller certification, and FAA Part 33, which governs airworthiness standards for engines.

We are targeting Type Certification by the FAA for the H500A under Part 33 in late 2025 or early 2026. A Part 33 certification will enable easier integration of the H500A on to Part 23 aircraft.

Batteries

Batteries

Electric aircraft require batteries, and we are operating with today’s battery capabilities. We purchase battery cells and integrate them into a proprietary module and pack assembly designed with features to deliver safer energy across multiple aircraft and non-aircraft platforms. Our batteries contain redundant protections against unlikely thermal runaway events, communication issues or non-uniform discharges. The packs we deliver meet stringent industry-standard regulatory requirements. The frequency of replacement can depend on various usage conditions, but we estimate the majority of customers will need to replace batteries every 12-24 months.

GSE and Multi-Modal Charging Network

108

##### Table of Contents

BETA’s Differentiated Footprint

We design and manufacture the mission-ready equipment needed to charge electric aircraft and supporting infrastructure. Our charge equipment uses the CCS-1 plug format adopted as the industry standard. Several electric aircraft operators have purchased our charging products for their facilities and vertiports. Our suite of products enables seamless reservations, billing and a zero-touch user experience. We believe this interoperability creates a strong network effect and further cements our leadership role in the industry.

Charge Cube – The Charge Cube is the central component of charging infrastructure. Its compact design, 50-foot charging radius and compliance with the CCS-1 standard allows compatibility with a broad range of emerging electric aircraft. Certified by Underwriters Laboratories, our Charge Cube offers differentiating features such as a touchless interface, automated cable management, reduced crew workload and enhanced safety.

Thermal Management System (TMS) Cube – The TMS Cube optimizes battery charging, performance and extends the lifespan of batteries. It pre-conditions and thermally manages aircraft batteries to enable efficient and reliable charging, especially in varying environmental conditions. Thermal management is vital to maximizing battery health and enabling fast charging. Other early-stage electric aircraft manufacturers are working to make their aircraft design compatible with our TMS product.

Mini Cube – The Mini Cube offers flexible, mobile fast charging for a variety of platforms including aircraft and ground vehicles. Its portability, integrated cable storage, and support for the CCS-1 protocol make it ideal for dynamic use in hangars and vertiports. The Mini Cube supports a clean and safe operational environment, while providing supplemental or backup charging capacity for diverse transportation assets.

Charging Products

As of August 31, 2025, we have commissioned 51 high-speed airport charging stations capable of recharging our ALIA CTOL or VTOL aircraft in as little as 20-40 minutes for average flights. This network has been funded almost entirely, by our customers and industry peers. Additionally, we have installed the first electric aircraft charger on a U.S. military base at Duke Field, which is part of the broader Eglin Air Force Base complex.

Large, Untapped Market Opportunity

We define our market opportunity in terms of our TAM, which is calculated based on the potential for new aircraft sales for commercial and defense applications, in addition to the lifetime revenue of potential aftermarket components and services. The aftermarket components and sales include batteries, motors, other components, maintenance, training and charging solutions.

We estimate the TAM for electric/hybrid aircraft to consist of approximately 60,000 units with an assumed value of $250 billion, using an average selling price of approximately $4 million per unit, through 2035. This is

109

##### Table of Contents

based on internal calculations derived from publicly available information and an analysis conducted by a global third-party consulting firm, not commissioned by us, which focused on passenger use cases. In addition, we have included incremental cargo, medical, defense and passenger use cases based on our market analysis and experience. We have further excluded certain geographic and aircraft use cases that are outside the scope of our intended business model. In addition to initial aircraft sales, we believe that each aircraft represents an estimated three times in incremental aftermarket revenue opportunity throughout its life, for an approximate value of $750 billion. We have developed CTOL and VTOL aircraft which can serve both commercial and end markets, cargo and logistics and passenger applications, to maximize the potential TAM.

Total Product Lifecycle

We believe that each aircraft we sell presents a larger long-term service and aftermarket revenue opportunity for additional value capture over a 20-year period.

As our global aircraft fleet grows, replacement batteries and maintenance requirements are also expected to grow. To support growing fleets of electric aircraft, charging infrastructure will be required at airports and vertiports globally.

In aviation, most maintenance requirements are recurring and non-deferrable, even during periods of economic downturn or reduced demand for commercial air travel.

We primarily compete across four end markets within the aerospace industry: cargo and logistics, medical, defense and passenger.

Cargo and Logistics: We believe cargo and logistics represent a near-term, sizable and compelling opportunity for our aircraft and products. Based on the demand for timely supply chain solutions caused by the rise of e-commerce, large global parcel and e-commerce companies have tested and placed orders for electric aircraft and drones to address supply chain constraints. In 2024, e-commerce made up approximately 16% of total retail sales in the United States based on the U.S. Census Bureau, 2024 Annual Retail Trade Survey. In

110

##### Table of Contents

parallel, customers are increasingly demanding faster delivery times, pressuring traditional distribution networks. The introduction of electric aircraft in cargo and logistics, specifically in rural areas, received additional support in the June 2025 Executive Order. Customers including UPS and Bristow have placed Firm Orders.

Medical: Electric aviation, both CTOL and VTOL, are well-suited to meet the growing demand for fast, reliable and environmentally sustainable healthcare logistics. Our aircraft are uniquely suited for medical operations with their large and flexible interior spaces. Lower operating costs of electric aircraft make them well-suited for Medical Cargo and Low-Acuity Patient Transfer missions. Customers including United Therapeutics, Metro Aviation and New Zealand Air Ambulance have placed Firm Orders.

Defense: Our ALIA platform is well suited for emerging necessities of modern warfare in both their low maintenance burden and their autonomy-ready designs. Current events and conflicts across the globe have resulted in increased defense and national security spending, both nationally and internationally. Existing defense logistics platforms, mainly helicopters, are poorly suited for imminent threats, including conflicts across wide expanses of ocean. In the United States, defense and national security spending benefits from strong bi-partisan support, which has resulted in a stable and growing investment over time. Our demand forecast consists of nearly 2,000 BETA aircraft for defense applications through 2035 based on DoD estimates and internal opportunity sizing. We believe the increased focus on lower cost, attributable and, where possible, dual-use technology that can be rapidly produced, will benefit us and aligns with our key focus areas.

Passenger: We believe that the demand for urban and regional air mobility services will usher in a new wave of growth for the commercial aerospace market. Based on 2024 schedule data, 20% of flights globally are under 300 miles, demonstrating this trend. As traditional, ground-based transportation alternatives become increasingly expensive and population growth accelerates, their scalability is becoming highly questionable. At the same time, technological advances in battery energy density, propulsion, design and materials are enabling aircraft to serve shorter distances in a more cost-effective and environmentally sustainable manner. The convergence of these forces has led airlines, aircraft lessors and charter companies to place orders for over ten thousand aircraft worth over $80 billion. We expect these trends to continue and create new opportunities to convert terrestrial transportation demand to aircraft.

Our Competitive Strengths

Simple Design along with a Strategic, Stepwise Approach to Derisk the Certification Process

Our certification strategy is purpose-built to advance new technology through a staged roadmap that we believe aligns with the FAA’s safety mission of “building confidence instead of friction.” This strategy advances our guiding principle, “safety through simplicity.” For example, if a component, joint or moving piece is not needed for safety on the aircraft—it is not on the aircraft. This clarity and decisiveness saves us a significant amount of time and effort as we seek certification across our product suite. In July 2025, the Hartzell Propeller received FAA Part 35 Type Certification, becoming the first propeller the FAA has certified for any electric aircraft.

We are taking a pragmatic approach that aligns with FAA frameworks, de-risks certification timelines and lays a scalable foundation for broader market success. This stepwise approach creates a logical progression where each certification effort informs the next — streamlining documentation, building continuity with FAA personnel and reducing risk across programs. Our market entry strategy mirrors this discipline by beginning with cargo and logistics and medical applications—lower-risk, high-value missions that can enable early revenue, generate real-world safety data and foster public trust ahead of passenger operations.

We are leaders in shaping policy through FAA collaboration and contributions to the development of policy needed for innovative technologies. We believe that we have built a trusted, influential relationship with the agency across all levels, enabling us to help shape regulation and accelerate progress first for BETA and thereafter for the entire industry.

111

##### Table of Contents

In July 2025, the FAA released Advisory Circular (AC 21.17-4), which covers type certification of powered-lift aircraft and sets out the requirements for airworthiness approval of eVTOL vehicles. Previously, eVTOL developers engaged with the FAA on an individual basis to agree on the G-1 certification basis for their aircraft, including a lengthy public comment process. In BETA’s case however, pursuant to AC 21.17-4, we were able to adopt the AC requirements as our certification basis, accelerating our path to certification. In August 2025, we closed our G-1 certification basis in under two weeks following the submission of our Stage 3 response to the FAA. Due to negotiations with the FAA and our advocacy for streamlined requirements that are optimized for our aircraft configuration within the final Advisory Circular, we were able to secure favorable certification requirements that are closely aligned with the SFAR adopted by the FAA in December 2024.

Certification Pathway

Vertically-Integrated Aerospace Company Developing the Core Technologies that Enable the Emerging Electric Aviation Ecosystem

We control and make proprietary batteries, motors, FBW systems and software for our aircraft. These core technologies are sought after by leading aerospace incumbents, further validating the demand for our products. These aircraft components are designed, manufactured and tested in our existing facilities.

Our vertical integration facilitates improve collaboration and communication across different stages, through our “approve then improve” strategy. We prioritize rigorous design, manufacturing, and testing protocols to ensure the highest quality products. This integration supports our ability to adapt swiftly to design and product changes, ensuring that we remain competitive and responsive to our customers’ needs.

112

##### Table of Contents

Our vertical integration allows for rapid iteration in the design and manufacturing process of our aircraft. The physical proximity of our R&D, manufacturing and testing facilities allows for faster collaboration and increased efficiency compared to a process reliant on many external suppliers. The capital investment in extensive manufacturing space enables us to scale to a rate of 300 aircraft per year at maturity, and we have site control for additional expansion. Further, our aircraft production lines are designed with the capability to produce both the CX300 and A250 aircraft on the same tooling. Common part applications across our aircraft programs, such as engines, batteries, FBW controls, avionics and landing gears, enable streamlined manufacturing processes and maximize operational efficiency.

Cargo and Logistics First Approach to Provide Nearer Term Market Entry

Our cargo and logistics ALIA CTOL facilitates early market entry. The cargo and logistics ALIA CTOL relies on standing rules and infrastructure to tap into an existing and growing logistics market. The demand from cargo and logistics and medical logistics operators is demonstrated by existing Backlog orders. Our CTOL aircraft easily integrates into the nation’s airspace and procedural landscape. Electric charging systems are the only additional infrastructure required, which we have been building for several years. We believe certifying our cargo and logistics ALIA CTOL airplane under FAA’s Part 23 relies on established rules to unlock revenue through the sale of type certified aircraft.

We believe the benefits of our cargo and logistics first approach will flow through to support the rapid progression of the passenger ALIA CTOL, along with all our ALIA VTOL programs. We expect to collect valuable operational data and flight experience through the use of our cargo and logistics ALIA CTOL by logistics and medical customers. We believe this data and experience will support passenger variant entry into service with a track record of safety and operational successes. It further allows us to continue building the infrastructure necessary to support our passenger customers’ urban and regional operations.

Our strategy carries across both our ALIA CTOL and VTOL platforms. Each aircraft is expected to enter service under a Type Certification for cargo and logistics operations first, followed by a passenger configuration through an amended Type Certification process. The significant similarity across the ALIA platform will ease the FAA’s Type Certification amendment process. As the only electric aircraft manufacturer with a clear cargo and logistics go-to-market strategy, we believe that we are well positioned to benefit from the rural logistics-focus of the June 2025 Executive Order – particularly in its directive for the FAA to allow the commercial use of electric aircraft prior to Type Certification.

Aftermarket-focused Business Model that Targets Recurring Revenue over Full Aircraft Lifetime

Our business strategy centers around leveraging aircraft sales to generate extensive recurring revenue at attractive margins over the lifetime of each aircraft. We plan to provide essential support throughout the operational lifespan of our aircraft, seeking to ensure continuous performance, safety and reliability. Our strategy prioritizes establishing diversified and consistent recurring revenue streams, servicing batteries, charging, maintenance and parts, creating a compelling opportunity for long-term profitability.

Battery replacements alone are expected to exceed the initial revenue from selling individual aircraft and provide higher margins. In a dynamic unique to electric aviation, replacement battery packs have the opportunity to increase the range of existing aircraft – increasing their utility.

Beyond BETA-built aircraft, selling our motors, batteries and other aircraft components to others extends our ability to leverage aftermarket recurring revenue at attractive margins.

Technologies

Our advantage is our technologies. We believe the core competency of our company and our core intellectual property are contained within our Enabling Technologies, which are fundamentally composed of four critical components:

| • |  | Batteries;

| • |  | Motors;

114

##### Table of Contents

| • |  | Ground Support Equipment; and

| • |  | Flight Control Systems.

Together, these Enabling Technologies create a vertically-integrated ecosystem across our product line. We designed each of these critical components for our electric aircraft and plan to use this technology in our ALIA CTOL (CX300), ALIA VTOL (A250) and MV250 aircraft, significantly reducing our overall development expense and creating economies of scale for production. Additionally, our Enabling Technologies have centralized, modular and interchangeable designs, enabling future generations of electric aircraft to incorporate our patented technologies. We also design and manufacture a line of aviation-centric charging equipment that features compatibility with a broad range of emerging electric aircraft. Our technologies are thoughtfully designed to enhance their lifetime value and long-term utility. These systems have applications across customers, sectors and geographies, which positions us for continued growth.

From time to time, we intend to enter into development arrangements with other aerospace manufacturers and governmental organizations for development activities. In the fiscal years ended December 31, 2024 and 2023, our research and development expenses were $206.9 million and $138.3 million, respectively. Our research and development expenses were $     million for the six months ended June 30, 2025. As of December 31, 2024, our principal revenue generating activities were comprised of activities pertaining to the development of our electric aircraft and the corresponding Enabling Technologies.

The following provides more information on the four critical components that make up our Enabling Technologies.

Motors

Electric propulsion systems differentiate our electric aviation category from conventional aircraft powered by combustion engines. We are positioned not only to design, manufacture and sell our motors, but integrate them across the entire electric value chain.

Our electric propulsion motors and inverters are based upon a simple design, free from heavy liquid cooling systems and gearboxes. Our flexible motor design allows them to be adapted into various configurations, including pusher, tractor and powerful vertical lift applications. We believe that we have made several important innovations in our motor designs that minimize mass while still providing high power and efficiency. For example, our H500 series of electric motors are on track to be the first electric motor certified by the FAA for integration into Part 23 aircraft and leads the industry in both maximum power output and power-to-weight ratio, weighing only 164 pounds while providing 572 horsepower based on internal testing. Our motors have significantly fewer parts than a traditional aircraft engine. Our motor test activities have accumulated a large set of usage data, both on our aircraft in flight and on various test stands, demonstrating their airworthiness, performance and reliability across an array of environmental conditions.

Our motors leverage air cooling to enable them to operate in a wide range of environmental conditions including temperatures as low as –40°C. Liquid cooled motors require special fluids to tolerate these low temperatures, whereas our motors only get more efficient at low temperatures. Additional benefits of air-cooled motors include the lack of drag caused by bulky radiators and reduced system weight, together yielding higher available payload weight and higher aircraft range.

Our high torque lift motors, with quad-redundant and high-power density operation, enable aircraft to take off and land vertically in every element. Our pusher motors feature dual-redundant, high-efficiency designs that provide aircraft with climb and range flexibility.

We believe these capabilities have resulted in high demand for our motors by OEMs seeking to incorporate them into their programs that require light, quiet, highly-efficient and powerful electric motors. Every BETA propulsion system is designed, validated, conformed and customized to the operational requirements of our customers and their mission.

115

##### Table of Contents

Currently, there is an entire industry ecosystem around manufacture and sales, financing, and services of conventional combustion engines for aircraft. A similar market opportunity is forming for electric propulsion systems. While still emerging, we believe we are positioned to lead in that evolving market and competitive landscape.

Batteries

We have developed and manufactured proprietary battery packs and energy storage systems in-house since 2019, with an emphasis on designing for long-range eVTOL and eCTOL applications. We demonstrated this with a proof-of-concept by flying our ALIA CTOL aircraft 336 nautical miles on one charge. The certification-intent CTOL aircraft, the CX300, carries 225 kWh of onboard energy with our current battery technology. Our aircraft has been purposefully designed around the energy storage system, with mounting provisions and volume allocations that provide flexibility to incorporate future cell technology advancements, including changes in form factor. This architecture will allow us to integrate battery improvements over time, enabling an opportunity to improve aircraft performance of an airframe over its life. We strategically prioritize range as a key differentiator, allocating a high weight fraction for energy storage while utilizing commercially available cells from high-volume production environments to ensure reliability and supply chain stability.

Safety forms the cornerstone of our battery design philosophy, supported by our dedicated battery test facility in St. Albans, Vermont. This facility enables high-throughput, data-rich destructive testing that has directly informed our iterative design process for thermal runaway containment systems and other aviation-specific safety features. The design of energy storage systems for aviation safety represents a core BETA competency, with our in-house testing generating extensive validation data that will streamline the certification process while ensuring the highest safety standards.

Our innovative modular approach features five identical 45kWh battery packs, each containing eleven substantially identical subpack modules, creating significant advantages across certification, manufacturing and operations. This modularity greatly simplifies verification testing by eliminating redundant test requirements and enabling compliance demonstration at appropriate system levels rather than requiring complete system testing to satisfy every requirement. The architecture allows all motors to nominally draw power from all battery packs as needed, creating the opportunity to configure the design of the aircraft with four or five packs depending on range and payload targets, without requiring significant architectural design changes. Additionally, this standardization of the design reduces manufacturing complexity by minimizing component variations, enabling more efficient production scaling while maintaining an economical price point for end customers.

Ground Support Equipment

We have developed a comprehensive network of GSE designed to enable the safe, efficient and scalable operation of electric aircraft. Our ground support ecosystem is powered by our modular charging products, which includes high-power Charge Cubes and mobile Mini Cube chargers and tower-based solutions. These systems are capable of efficient charging across both aircraft and ground vehicles and the Charge Cubes are UL-certified. Our suite of ground support systems has been built and installed across dozens of airports and logistics hubs in North America – and this infrastructure is continuing to grow. Our GSE reflect our commitment to building the entire electric aviation ecosystem, which critically includes the infrastructure underpinning the category’s growth. Importantly, we believe this owned infrastructure will further grow our topline performance and diversify its revenue mix as the enterprise scales.

Flight Control Systems

The flight control computers are the heart of our FBW control architecture. Our aircraft have three FCCs each, providing triplex redundancy and ensuring continued safe operation, even in the event of a failure. The FCCs take in data from the pilot controls, systems status and critical sensors, such as airspeed and altitude, and

116

##### Table of Contents

then send commands to the flight control surfaces and propulsion motors to carry out the pilot’s intent. The FBW system enhances the safety of every flight while saving the weight and complexity of a conventional mechanical control system. Additionally, the thoughtful design of our FCCs helps prepare each aircraft we build to be flown autonomously in the future. We provide our FCC technology to other aircraft manufacturers as a merchant supplier.

Aircraft Design and Engineering

In addition to the design and development of our Enabling Technologies, we have created significant in-house capabilities in the design and engineering of electric aircraft, electric aircraft components and airport charging systems. We design and engineer airframes, interiors, heating and cooling and low voltage electrical systems in-house and in conjunction with our suppliers, partners and customers, to ensure our products meet the requirements of our customers.

We have developed our substantially integrated, electric aircraft manufacturing Final Assembly Facility with the goal of obtaining Production Certification from the FAA. Our engineering and manufacturing teams work alongside one another in an effort to accelerate the development of our electric aircraft. We believe the co-location of our engineering and manufacturing teams will help accelerate the development of new products and allow for faster introduction of product changes.

Manufacturing

Aircraft Assembly & Quality Control

Our Final Assembly Facility is designed for flexibility and scalability, configured to meet our expected production rate needs through 2027 without significant additional investment, and we anticipate that the current approximately 188,000 square foot facility will support CX300 and A250 production until 2029 without substantial additional floorspace requirements. The facility is vertically integrated, enabling us to build all wire harnesses, assemble flight control computers, inverters, electronic assemblies, manufacture our electric engines, assemble our battery packs, and perform aircraft structural assembly and final assembly in-house. This integration is further enhanced by our internal metallics machining and composites fabrication capabilities that support production operations. Our aircraft production lines are designed with the capability to produce both the CX300 and A250 aircraft on the same tooling. Common part applications across our aircraft programs, such as engines, batteries, FBW controls, avionics and landing gears, enable streamlined manufacturing processes and maximize operational efficiency.

As our aircraft production volumes grow, we believe that we will be able to enhance production capacity through the improvement of labor utilization and operating leverage. Costs of materials can be expected to improve as we enter long-term agreements with suppliers targeting higher production volumes. Additionally, there is opportunity to leverage innovation in aircraft structure design to minimize the cost and the number of components required to build each aircraft, without compromising on safety. To support our continued growth in operations, we have developed internal training curriculum and programs and have engaged in local workforce development efforts, ensuring we will maintain a skilled, local workforce capable of meeting aerospace manufacturing standards.

Our centralized quality team is integrated throughout the entire aircraft manufacturing process. From supplier onboarding through procurement, incoming inspection and internal manufacturing of all components, systems and complete aircraft, our quality team verifies that our production is performing to the high standard of excellence we have set. These quality professionals ensure we have implemented processes to build conforming hardware that meets the design definition in our technical data package and then verify compliance, maintaining the high standards required for aerospace applications. Our manufacturing operations run off of an integrated Enterprise Resource Planning and Manufacturing Execution System that has been implemented at BETA for a

117

##### Table of Contents

number of years, and We are continuing to roll out an internal Quality Management System that positions us for future Production Certification requirements, informed by CFR Part 21 Subpart G, establishing the foundation for scalable production that meets rigorous aerospace standards.

Suppliers

Suppliers are an important stakeholder group in the manufacturing of our aircraft. We purchase certain component systems, such as avionics, sidesticks, servos, and various forms of aircraft structures, from suppliers. Our supply base is located globally, with about 90% of our suppliers located in North America, 9% in Europe and the remaining 1% in Asia as of June 30, 2025. We have developed close relationships with several key suppliers particularly in the procurement of lithium-ion cells and certain electric propulsion components. See also “Risk Factors—Risks Related to Our Business and Industry—We depend on suppliers and service partners for raw materials and certain parts and components.”

We use various raw materials in our business including pre-impregnated carbon composites, aluminum, titanium and stainless steel. The prices for these raw materials fluctuate depending on market conditions and global demand for these materials. We believe that we have adequate supplies or sources of availability of the raw materials necessary to meet our manufacturing and supply requirements.

We have implemented enterprise resource planning and management software to automate our procurement and inventory processes and integrate them with our financial accounting. We plan additional investment in our management systems to support further growth in our operations.

Customers and Selected Relationships

We currently sell our aircraft components and GSE to civil aircraft operator, aerospace and defense (“A&D”) OEMs, and ground support operators.

Our aircraft components include but are not limited to electric motors, batteries, and flight control computers. Our GSE includes, but is not limited to, charge cubes, mobile Mini Cube chargers and thermal management systems.

Our customers span from airlines, logistics operators, medical providers, and aircraft lessors to defense contractors, and aerospace manufacturers. Further our vertical integration enables key customer groups to include cargo and logistics operators, vertiport operators and fixed base operators through ground support systems.

Our range of products have gained traction with defense customers within the DoD, highlighting the capability of our technology across the private and public sectors.

Commercial Aircraft Customers

We have an existing civil aircraft Backlog of 671 aircraft worth $2.63 billion, of which 174 are for Firm Orders and 497 are for Options. Our current civil aircraft customers include UPS, United Therapeutics, Air New Zealand, Bristow and Metro Air Services. Additionally, we currently have a letter of intent with Republic Airways relating to the use of our aircraft to fulfill its missions. These customers highlight the diversity of civil uses for our aircraft ranging from cargo and logistics to medical to passenger missions. Importantly, in addition to selling aircraft, we also intend to sell a full suite of support products to these aircraft operators. Many of these products are similar to what is conventionally sold to aircraft operators from aircraft producers (e.g., flight training, aftermarket parts), but because we own the intellectual property and produces all key components onboard the aircraft, we can also sell key aftermarket replacements such as batteries through either direct replacement or the industry’s first ‘energy by the hour’ program.

118

##### Table of Contents

Commercial Component Customers

The core Enabling Technologies outlined above have earned a strong, positive reputation among other A&D OEMs. We have already begun selectively selling these components to other customers within the aviation industry and beyond. Current customers in this category include established A&D OEMs and others.

Commercial GSE Customers

We produce the GSE required to enable not only our aircraft operations, but also the aircraft operations of other advanced air mobility (“AAM”) aircraft. Our CCS-1 standard chargers currently lead the industry and are installed in 49 locations in the United States with additional sites already under contract.

Current customers and partners include fixed base operators like Signature Aviation and Atlantic Aviation; aircraft customers like United Therapeutics; other AAM OEMs like Archer Aviation and Vertical Aviation; as well as government entities like State of Michigan and U.S. Department of Health and Human Services. We also provide such customers a variety of value-added services throughout the lifecycle of certain pieces of equipment, like the charger. These services include a suite of connected technologies that provide streams of data, transaction services and insights to our customers.

Defense Customers

Defense applications for all of our products continue to highlight the utility of our products across the private and public sectors. Our products are built to meet the needs of both types of customer, which highlights their dual-use nature. Over the years, we have cultivated and maintained strong working relationships with key branches of the military, including the United States Air Force (since 2019) and Army (since 2021). For example, we have collaborated with the U.S. Air Force’s Agility Prime program, where we have explored the potential use of our electric aircraft to further certain logistical, medical evacuation and intelligence missions. Since our inception, we have collected approximately $50 million through U.S. Air Force and U.S. Army contracts on research and development areas such as VTOL, hybrid, and further development around future autonomous flight.

We plan to continue to expand our relationships with defense and government customers and advance our military capabilities with cutting-edge technology tailored to modern defense needs. See Note 3 of our consolidated financial statements included elsewhere in this prospectus for additional information about our arrangements with the DoD.

Regulatory

We are subject to various government regulations and may in the future be subject to heightened U.S. government regulation as a contractor or subcontractor to one or more U.S. governmental organizations. Among the most significant U.S. government regulations that currently or may in the future affect our business are:

| • |  | the Federal Acquisition Regulation (the “FAR”) and supplemental agency procurement regulations, which comprehensively regulate the formation, administration and performance under government contracts;

| • |  | the National Industrial Security Program Operating Manual Rule, which establishes the security guidelines for private companies participating in classified programs or accessing classified information in connection with a government contract and imposes certain foreign ownership, control or influence mitigation measures based on foreign involvement in such private companies;

| • |  | the Committee on Foreign Investment in the United States, which is tasked with reviewing the national security implications of foreign acquisitions of and investments in U.S. businesses;

119

##### Table of Contents

| • |  | the False Claims Act, which imposes substantial damages and penalties in connection with a misrepresentation made in connection with a request for payment by the U.S. government, and the False Statements Act, which, imposes penalties on the basis of false statements to federal agencies, even if not made in connection with a payment; and

| • |  | laws, regulations and executive orders restricting the use and dissemination of information classified for National Security purposes and the exportation of certain products and technical data.

We view our aircraft and related services to qualify as commercial products and services as defined in the FAR as our aircraft and related services will be available for sale in the commercial marketplace. In some cases, we may make minor modifications to our aircraft for defense applications. Companies that provide commercial products and services to the U.S. government avoid certain regulatory compliance requirements that might otherwise apply including the need to make disclosures under the Truthful Cost or Pricing Data Statute (formerly the Truth in Negotiations Act) and technical government contract cost accounting rules (Cost Accounting Standards and Cost Principles). Should the U.S. government determine that our products and services do not qualify as commercial products and services under the FAR, we would be subject to such disclosure, cost accounting requirements among other compliance and audit requirements.

We also need to maintain our facility security clearance as an organization, and certain of our employees must maintain personnel security clearances to continue working on and advancing certain of our programs and contracts with the U.S. government (whether directly with the U.S. government, or indirectly through a subcontract with a prime contractor). To the extent we are involved in them, classified programs generally require that we comply with various Executive Orders, federal laws and regulations and customer security requirements designed to protect classified information that may include restrictions on how we develop, store, protect and share such information.

In addition, we are subject to industry-specific regulations due to the nature of the products and services we provide. For example, certain aspects of our business are subject to further regulation by additional U.S. government authorities, including (i) the Federal Aviation Administration, which regulates the design and production of aircraft in the U.S. and the airspace for all air vehicles in the National Airspace System, (ii) the National Telecommunications and Information Administration and the Federal Communications Commission, which regulate wireless communications in the United States and (iii) the Directorate of Defense Trade Controls of the U.S. Department of State that administers the ITAR, which regulate the temporary import, export, reexport and transfer of controlled technical data, defense articles and defense services, as discussed further in “—International Traffic in Arms Regulations and Export Controls.”

The nature of the work we do for the federal government and others may also limit the parties who may invest in or acquire us. Export laws may keep us from providing potential foreign investors with a review of the technical data pertaining to our technology, which would likely be central to such a potential investment. Moreover, investments, directly or indirectly, by investors may be subject to regulatory review and approval requirements, or ultimately prohibited, by governmental entities. See also “Risk Factors—Risks Related to Laws and Regulations—We are subject to stringent U.S. export and import control laws and regulations, which may change. We may be unable to comply with these laws and regulations or U.S. government licensing policies, or to secure required authorizations in a timely manner.”

In addition, the export from the United States of certain of our products may require the issuance of a license by the Bureau of Industry and Security of the U.S. Department of Commerce under the Export Control Reform Act of 2018 and the EAR. Some of our products may also require the issuance of a license by the Directorate of Defense Trade Controls of the U.S. Department of State under the Arms Export Control Act and its implementing regulations, the ITAR, which licenses are generally harder to obtain and take longer to obtain than do licenses under the EAR.

We are subject to laws that may limit the use or other processing of personal information gathered online and that require online services to establish privacy policies.

##### Table of Contents

International Traffic in Arms Regulations and Export Controls

Our business is subject to, and we must comply with, stringent U.S. import and export control laws and regulations, including the ITAR and the EAR. The ITAR generally restrict the export of hardware, software, technical data and services that have defense or strategic applications. The EAR similarly regulate the export of hardware, software and technology that have commercial or “dual-use” applications (i.e., for both military and commercial applications) or that have less sensitive military or aerospace-related applications that are not subject to the ITAR. The regulations exist to advance the national security and foreign policy interests of the United States.

The U.S. government agencies responsible for administering the ITAR and the EAR have significant discretion in the enforcement of these regulations. The agencies also have significant discretion in approving, denying or conditioning authorizations to engage in controlled activities. Such decisions are influenced by the U.S. government’s commitments to multilateral export control regimes.

Many different types of internal controls and efforts are required to ensure compliance with such export control rules. In particular, we are required to maintain a registration under the ITAR; determine the proper licensing jurisdiction and classification of hardware, software, technical information and defense services; obtain licenses or other forms of U.S. government authorizations to engage in activities, including the performance of services for foreign persons, related to and that support our business; and manage physical access and security accordingly. Such regulations require authorization prior to the release of controlled technology to foreign persons, including employees, customers, suppliers and other foreign persons. See also “Risk Factors—Risks Related to Laws and Regulations—We are subject to stringent U.S. export and import control laws and regulations, which may change. We may be unable to comply with these laws and regulations or U.S. government licensing policies, or to secure required authorizations in a timely manner.”

Certification

Type Certification

In the U.S., new aircraft must undergo a rigorous FAA certification process to ensure the design, manufacturing, and individual aircraft meet all applicable safety and airworthiness standards. This begins with Type Certification, in which the FAA evaluates the aircraft design through extensive ground and flight testing to verify compliance with federal regulations. The production facility must obtain a Production Certificate, which confirms that the manufacturer’s facilities, quality systems, and procedures can reliably produce aircraft that conform to the approved type design. Once both the Type and Production Certificates have been issued to the OEM, each aircraft produced can receive a Standard Airworthiness Certificate, authorizing it to operate within the National Airspace System. We plan to initially certify our aircraft for cargo and logistics operations under Visual Flight Rules and Instrument Flight Rules, for flights during both day and night. Following initial certification, we intend to amend our type certificate which will allow us to modify the aircraft design to include approval for medical logistics, flight into known icing conditions and additionally passenger missions.

We began working with the FAA in 2020 and have made significant progress toward the certification of both our eCTOL airplane and our eVTOL aircraft, as well as the certification of our engines for integration in aircraft certified under FAA Part 23 and 14 CFR 21.17(b), as determined by the FAA. Following the first flight of our initial production-intent eCTOL airplane in 2024, we have built multiple production-intent airplanes and secured FAA Special Airworthiness Certificates to support continued flight testing and market survey operations. Our electric aircraft have collectively logged over 785 hours using electric propulsion alone, demonstrating both technical maturity and operational readiness as we advance toward Type Certification.

The Type Certification process can be thought of in five stages. Each phase is a milestone that reduces the risk of the product, builds regulatory trust, and unlocks commercial value. Stages one to three can be considered the “definition” phase, while stages four and five are the “implementation” phase. Progress in Type Certification

121

##### Table of Contents

is not always linear, meaning it is possible to make simultaneous progress in different stages on different aircraft parts or systems, depending on their maturity. Effective certification is a partnership between applicant and regulator since this process involves close coordination in working to align on mutually accepted outcomes. Our projections are strengthened with each functional completion of a specific phase. Functional completion allows for some items to be kept open until the end of the project but allows for a state of maturity where we can move into the next phase and iterate as necessary.

| • |  | Stage 1 – Conceptual Design: The Company works with the FAA to define the scope of the Type Certification project and submit the certification plan. This initiates formal FAA oversight and the timeline towards Type Certification.

| • |  | Stage 2 – Requirements Definition: The Company looks for alignment with the FAA on which safety and performance standards apply. This locks in the regulatory targets we’re certifying to.

| • |  | Stage 3 – Compliance Planning: The Company and the FAA design the roadmap that defines how we will demonstrate the aircraft meets FAA standards. This stage aligns all parties on the path to approval.

| • |  | Stage 4 – Implementation & Testing: The Company plans, documents and completes thousands of inspections, tests and analyses in accordance with the certification plans previously drawn up in the third stage to submit for FAA approval. This is the core phase of demonstrating compliance, safety and reliability. The results are verified by the FAA and a Type Certificate is issued.

| • |  | Stage 5 – Post-Certification: This phase is intended for maintaining and scaling through fleet monitoring and in-service reporting, as well as validating with other countries and applying for amended Type Certification. This enables market expansion, global sales, and long-term safety.

With a mature design informed by over 785 flight hours in our electric aircraft, we are making strong progress toward Type Certification. We are actively engaged with the FAA, progressing through the extensive testing and validation required to achieve FAA Type Certification.

We expect the FAA Type Certification will be recognized by certain international regulators through bilateral aviation safety agreements between the FAA and their counterpart civil aviation authorities. This reciprocal recognition provides the regulatory foundation for civil operation of our aircraft in non-U.S. markets. Following FAA Type Certification, we intend to pursue validation with Transport Canada and the Civil Aviation Authority of New Zealand, in support of firm customer orders. We have also initiated discussions with the European Aviation Safety Agency (EASA) regarding validation of H500A and CX300. We anticipate we will start the validation process on H500A with EASA immediately following FAA Type Certification or in 2026.

In June 2025, at a press event at the Paris Air Show, the DOT and FAA announced the recent work done by the National Aviation Authorities Network, unveiling a joint roadmap to harmonize global certification of AAM aircraft. This initiative enables participating regulators to adopt streamlined validation processes thus expediting validation and aligning on safety standards. These arrangements provide a means of efficient international expansion as we develop commercial operations around the world.

As a first mover in electric aviation, we are helping to shape the regulatory framework that will define the future of flight. Our path to certification leverages a large body of existing processes, procedures and standards. However, as one of the companies leading this next generation of the aviation industry, many of the rules necessary for electric aircraft and, in particular, eVTOL certification and operations, are still being finalized by the FAA. As these frameworks continue to take shape, the existing rules and regulations may be revised, or we may see additional requirements imposed that would extend our timeline for certification. While this pioneering role brings some added complexity, it also positions us to set the standard for the industry.

Production Certification

We are developing the systems, procedures, and quality assurance processes required to obtain FAA Production Certification, which will authorize us to manufacture our electric aircraft with the FAA-approved

122

##### Table of Contents

type design. We intend to obtain Production Certification for our approximately 188,000 square foot manufacturing facility after we receive Type Certification for the aircraft, and we have built our production facility and developed our processes and systems with the necessary requirements in mind. We build the motors, batteries, charge control, flight control and computers at our manufacturing facility, which will likely support our production rates for the next four years.

Other Certifications

We plan to deliver comprehensive factory training programs for both pilots and maintenance personnel operating the CX300. These programs are designed to support Part 135 operators by preparing their initial cadre of pilots and maintainers, and by providing high-quality training materials that can be integrated into their FAA-approved initial and recurrent training programs.

In May 2022, the FAA indicated that it was revisiting the decision to certify all eVTOLs under Part 23 and would, instead, require certification under the “powered lift” classification. In October 2024, the FAA published a Special Federal Aviation Regulation that includes pilot certification and operational regulations for eVTOL aircraft. For the A250, we intend to establish a Part 142 training center, equipped with a certified Flight Simulation Training Device and in-aircraft instruction. This will enable the delivery of powered-lift Category Ratings, Instrument Ratings, A250 Type Ratings, and Part 135 initial training. In parallel, an enhanced factory training program for A250 maintenance teams will ensure operators are equipped to support sustained, safe operations.

We plan to obtain a Part 145 Repair Station Certificate, which would authorize us to perform maintenance, repair and overhaul services for our electric aircraft engines and subsystems once they are certified and in commercial operation. This capability will enable us to support fleet reliability and long-term service readiness, following delivery to our commercial customers.

Our operations may become subject to additional federal, state and local requirements in the future.

Policy Engagements with Decision Makers & Communities

Our business requires collaboration with decision and policy makers at the local, state and federal level of government.

At the federal level, we have built trusted relationships, drawing support not just from our home states of Vermont and New York, but also from areas where our customers and suppliers are rooted. On the defense side, that has yielded funding for key DoD programs, from operational deployments to work on hybrid systems and autonomy. On the civil side, we have helped shape major aviation policy. Our founder, President and Chief Executive Officer, Kyle Clark, testified before Congress as a witness during the FAA Reauthorization process, offering an industry voice on how to accelerate AAM certification and keep the U.S. ahead in the global aviation race. That effort led to a first-of-its-kind pilot program allowing FAA airport funds to be used for charging infrastructure, directly supporting infrastructure readiness. We also recently became the first electric aircraft manufacturer to host FAA Administrator Rocheleau.

We engage with state and local leaders to prepare for the arrival of Advanced Air Mobility. We have partnered with more than 30 states to share insights, identify infrastructure opportunities, and shape policies designed to ensure they are ready when AAM is certified. In New York, we recently demonstrated our technology at New York Airports in collaboration with the Port Authority of New York and New Jersey. The event drew state leaders, highlighting the growing momentum around AAM and our industry leadership. With a flight test base in Plattsburgh, New York, we have built deep relationships with county and state officials, which has resulted in state funding for growth and workforce development programs. In Utah, after visiting all three leading AAM OEMs, state officials selected BETA as their partner to help bring this new transportation mode to

their communities. In North Carolina, our engagement helped catalyze the state to issue its first request for information on electric aircraft. In Michigan, we have secured over $2 million for the deployment of charging infrastructure. Across the country, states are stepping up to lead on AAM, and they are the resource they are coming to as they look to build that vision.

In our home state of Vermont, we are recognized as a leading employer and a key contributor to the state’s future. We have built strong partnerships with state and local officials, regularly advising on public policy issues from infrastructure and housing to workforce development. We regularly host legislative tours to share insights on the innovation economy and what it takes to grow in Vermont.

Regulation – Battery Safety and Testing

Recent breakthroughs in battery technology are playing a pivotal role in the emergence of the AAM sector, which is set to revolutionize aviation with clean, efficient, electric-powered aircraft. Although battery applications in aviation come with specific technical hurdles, continuous progress in engineering, validation, and safety standards is driving the industry toward exceptional reliability. These innovations are shifting the focus from a pre-prescribed containment focused pathway to a standard systems safety approach that allows for typical aerospace techniques used to develop systems to a very high reliability standard, including prevention and layered mitigations, reducing the likelihood of critical failures to near-zero levels. This evolution positions AAM as an equivalent level of safety for air travel, and also a key enabler in the transition to a more sustainable and efficient transportation ecosystem.

Like other components of our aircraft, the batteries used for propulsion must be shown to satisfy regulatory requirements during the Type Certification process. Currently, the industry has limited in-service experience with use of lithium-ion batteries for aircraft propulsion, and existing regulations may not fully address all criteria such batteries will be required to satisfy in a particular application. Therefore, although industry standards exist with respect to some aspects of this technology, the airworthiness criteria applicable to a particular aircraft and means of demonstrating compliance are subject to determination by the FAA on a project-specific basis. We are actively engaged with the FAA over certification of the batteries, and anticipate that we will successfully demonstrate compliance to various operational and safety requirements during the Type Certification process. As the use of batteries for aircraft propulsion represents a cutting-edge use of technology, it is possible that FAA requirements may be revised, thereby potentially extending our timeline for certification.

Further, our batteries are subject to various U.S. and international regulations that govern transport of “dangerous goods,” defined to include lithium-ion batteries, which may present a risk in transportation. We conduct testing to demonstrate our compliance with such regulation.

The governing regulations, which are issued by the Pipeline and Hazardous Materials Safety Administration (“PHMSA”) are based on the UN Recommendations on the Safe Transport of Dangerous Goods Model Regulations and related UN Manual Tests and Criteria. The regulations vary by mode of transportation when these items are shipped such as by ocean vessel, rail, truck or by air. We are actively working with PHMSA to enable air cargo transport of our large lithium batteries and expect approval in the near future.

We have completed the applicable transportation tests for the battery packs we are currently producing, demonstrating our compliance with the UN Manual of Tests and Criteria, including:

| • |  | Altitude simulation – simulating air transport;

| • |  | Thermal cycling – assessing cell and battery seal integrity;

| • |  | Vibration – simulating vibration during transport;

| • |  | Shock – simulating possible impacts during transport;

| • |  | External short circuit – simulating an external short circuit; and

| • |  | Overcharge – evaluating the ability of a rechargeable battery to withstand overcharging.

The cells in our batteries are composed mainly of metal oxides. The cells do not contain any lead, mercury, cadmium or heavy metals. In addition, our batteries include packaging for the lithium-ion cells. This packaging includes trace amounts of various hazardous chemicals whose use, storage and disposal is regulated under federal law. We currently have an agreement with a certified third-party battery recycling company to recycle our battery packs. See also “Risk Factor—Risks Related to Our Business and Industry—Crashes, accidents or incidents of electric and hybrid aircraft, as well as accidents or incidents involving battery solutions, such as lithium-ion batteries, could have a material adverse effect on our business, results of operations, financial condition and prospects.”

Regulation – Charging Infrastructure

Our charging network is currently installed at airports across the country, and our Charge Cube is certified by Underwriters Laboratory. Our Mini Cube charger is compliant with Underwriters Laboratory standards but will require Underwriters Laboratories certification to be used broadly by the end-customer as a plug-in appliance. Furthermore, as noted above under “—Policy Engagements with Decision Makers & Communities,” we must successfully seek and obtain permits with the various municipalities that control the airports at which our charging infrastructure is and will be installed. These permits are required to install and maintain the installed Charge Cubes. FAA involvement will be required to secure ground leases for the land on which our charging equipment will be installed and operated at grant obligated airports. Installation of additional chargers could require obtaining approval from a public regulatory body, such as city council, airport commission or other governmental authority. In addition, our charging equipment may be subject to local taxes and fees and EHS and other laws and regulations.

Regulation – EHS

We are subject to a variety of increasingly stringent foreign, federal, state, and local EHS laws, regulations and ordinances relating to the protection of the environment, including those relating to emissions to air and other environmental media, discharges (including storm water) to surface and subsurface waters, safe drinking water, wildlife preservation, operational constraints like noise abatement, including relating to aircraft noise, and the use, management, disposal and release of, and exposure to, hazardous substances, oils and waste materials. Some of these laws and regulations require us to obtain permits, which contain terms and conditions that impose limitations on our ability to emit and discharge hazardous materials into the environment and may be periodically subject to modification, renewal and revocation by issuing authorities. We may also be subject to potential strict, joint and several liability for the investigation and remediation of contamination, including contamination caused by other parties, that may exist at properties we currently own, lease or operate and previously owned, leased or operated and at other properties where we or our predecessors have arranged for the disposal of hazardous substances. We are or may be subject to new or proposed laws and regulations that may have a direct effect (or indirect effect through our third-party relationships) on our operations. Any such existing, future, new or potential laws and regulations could have an adverse impact on our business, results of operations and financial condition. See also “Risk Factors—Risks Related to Laws and Regulations—We could incur significant costs in complying with EHS laws and regulations and could be adversely affected by liabilities or obligations imposed under such laws and regulations.”

Our operations are subject to several federal and state laws and regulations, including the federal Occupational Safety and Health Act (“OSHA”) and comparable state statutes, the purpose of which is to protect the health and safety of workers. The Occupational Safety and Health Administration is the principal federal regulator of safety in the workplace. OSHA governs safety requirements in our manufacturing and aircraft maintenance operations. For example, employees may be required to wear certain personal protective equipment when performing manufacturing or maintenance-related tasks. In addition, the OSHA hazard communication standard, the Environmental Protection Agency community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning hazardous materials used or produced in operations and that this information be provided

125

to employees, state and local government authorities and citizens. Every employee is trained in the safety policies and procedures that are relevant to their role, and we encourage all employees to participate in company-wide safety initiatives, including participating in our non-punitive safety reporting program to identify hazards and reduce risks.

Competition

We believe that the primary sources of competition for offerings are conventional air transport solutions and manufacturers or other suppliers of other electric aircraft and related products and services, including batteries, motors, components, maintenance, training and charging solutions. We are not a commercial aircraft operator and do not intend to provide passenger or cargo and logistics services.

We believe the primary factors that will drive success in the electric and hybrid electric aviation (including VTOL) market include:

| • |  | the ability to certify the aircraft and commence commercial production in a timely manner;

| • |  | the ability to produce and sustain products that meet the commercial and operational requirements of real-world operators;

| • |  | the ability to manufacture efficiently at scale;

| • |  | the ability to scale adequately to drive down product pricing;

| • |  | the ability to capture first-mover advantage, if any;

| • |  | the ability to develop or otherwise capture the benefits of next generation technologies; and

| • |  | the ability to deliver products and services to a high-level of quality, reliability and safety.

We believe that our aircraft and vertically-integrated approach offer the greatest long-term prospects to certify and produce the best aircraft to serve our customers and, in turn, monetize the full value chain from initial development through commercialization and ongoing operations. Others have differentiated products and approaches, but BETA is positioned to capture opportunity across the entire electric aviation ecosystem.

Seasonality

Seasonality does not have a material impact on our business. Our products and services are sold and delivered throughout the year, and demand patterns remain generally consistent across quarters. While we may experience timing variations in customer orders and deliveries due to factors such as project schedules or individual customer procurement cycles, these fluctuations are not driven by seasonal trends and have not had a material effect on our results of operations.

Intellectual Property

Our success is rooted in part, in our ability to safeguard our core technology and intellectual property. To establish and protect our intellectual property and other proprietary rights, we rely on patents, trademarks, copyrights, and trade secrets. We also enter into license agreements, confidentiality and non-disclosure agreements with third parties, employees and contractors to restrict third party access to and disclosure of our proprietary information. We rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection and have measures in place designed to protect our proprietary information and other technological innovations.

As of August 31, 2025, we have over 447 issued patents worldwide (a majority of which are U.S. filings) and over 176 pending patent applications (of which over 124 are U.S. filings). The patent portfolio is primarily related to the technology supporting our electric aircraft, propulsion, control systems, GSE, Enabling Technologies and various charging systems. We regularly solicit disclosures and hold invention harvesting events in order to file patent applications on the latest solutions for our products.

126

##### Table of Contents

As of August 31, 2025, we own 8 U.S. trademark registrations, 9 U.S. trademark applications, 11 foreign trademark registrations and 10 foreign trademark applications.

We have procedures in place to monitor for potential infringement, misappropriation or other violation of our intellectual property or proprietary rights, and it is our policy to take appropriate action to defend and enforce our intellectual property, taking into account the strength of our claim, likelihood of success, cost, and overall business priorities. However, the steps we take may not be adequate and could harm our reputation and could adversely affect our competitive position, financial condition or results of operations. See also “Risk Factors—Risks Related to Our Business and Industry—We may be unable to seek, obtain, maintain, protect or enforce our intellectual property rights, or to otherwise defend enforce our intellectual property rights from unauthorized access or use by third parties.”

Information Technology and Cybersecurity

Given the interconnected and collaborative nature of our operations, from initial aircraft design through certification, manufacturing, and aftermarket support, we rely on complex information technology systems and infrastructure to support our operations and business activities. Our business depends on a number of critical systems including (i) enterprise applications for business operations, financial management, supply chain management, production, design, and testing, (ii) network and cloud infrastructure supporting our research and development, testing, and manufacturing facilities, (iii) integrated software systems in our aircraft and GSE, (iv) data platforms that process operational and customer information and (v) cybersecurity measures protecting our data and systems. Additionally, we plan to provide software and data systems to our customers that utilize data connectivity and analysis to monitor aircraft performance, enhance safety, and optimize operations, which will require us to collect, store, and process proprietary data from our customers, aircraft, and GSE.

Sustainability

By developing an energy efficient, fully electric, zero-emissions aircraft, we believe we can help reduce the aviation industry’s environmental impact over time.

We are building a dedicated workforce to achieve this goal while aiming to adhere to best practices in risk assessment, mitigation and corporate governance. To oversee all considerations relating to sustainability, including environmental impact, building a safe and engaged working environment, and establishing strong corporate governance, we will establish the nominating and corporate governance committee of our Board, prior to the completion of this offering, in addition to our management team.

| • |  | In addition to developing and producing innovative aircraft that reduce environmental resource use and energy consumption compared to traditional aviation and other modes of transportation, we aim to be stewards of the environment by minimizing the impact of our own operations. Current initiatives include tracking energy consumption and material inputs and outputs of our operations, with impact reduction efforts for greenhouse gas emissions and waste. As our domestic manufacturing footprint grows, we strive to source renewable energy for all primary facilities in a cost-effective manner, to reduce greenhouse gas emissions associated with our manufacturing. Further, as our testing and production operations have scaled, we have continued to recycle our aircraft batteries and are actively evaluating other product life cycle impacts.

We believe that this focus allows us to recognize cost savings through resource efficiency, build positive community relationships and more effectively manage environmental risks and opportunities.

| • |  | We believe that providing high quality jobs that are supportive of and welcoming to all can minimize employee turnover, build a resilient workforce and support positive community relationships. We underpin all of these activities with a core focus on health and safety.

| • |  | We maintain our commitment to ethical business conduct, integrity and corporate responsibility by integrating strong governance and enterprise risk management oversight across all aspects of our business.

Kamen, General (RET) James McConville and     will be assigned to Class I; David Churchill, Mike Stone and     will be assigned to Class II; and Kyle Clark, Charles Davis, Dr. Martine A. Rothblatt and     will be assigned to Class III. At each annual meeting of stockholders, directors will be elected to succeed the class of directors whose terms have expired. As a result, only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective three-year terms. Each director’s term will continue until the election and qualification of his or her successor, and his or her earlier death, resignation, retirement, disqualification or removal.

This classification of our Board could have the effect of increasing the length of time necessary to change the composition of a majority of the Board. In general, at least two annual meetings of stockholders will be necessary for stockholders to effect a change in a majority of the members of the Board. Our directors are removable only for “cause.” See the section titled “Description of Capital Stock–Anti-Takeover Effects of Provisions of Our Charter, Our Bylaws and Delaware Law” for a discussion of other anti-takeover provisions that are included in our Amended and Restated Certificate of Incorporation that becomes effective immediately prior to the completion of this offering.

In evaluating director candidates, we will assess whether a candidate possesses the integrity, judgment, knowledge, experience, skills and expertise that are likely to enhance the Board’s ability to manage and direct our affairs and business, including, when applicable, to enhance the ability of the committees of the Board to fulfill their duties.

In connection with this offering, our Board has undertaken a review of the independence of each director. As a result of this review, our Board has determined that, with the exception of management directors, all other members of the Board are independent under NYSE listing standards.

Controlled Company Exception

After the completion of this offering, the Class B Common Stockholder will continue to beneficially own a majority of the voting power of our capital stock through his ownership of all of our outstanding shares of Class B common stock, which are entitled to 40 votes per share. As a result, we will be a “controlled company” within the meaning of the NYSE corporate governance standards, and therefore we are permitted to, and we intend to, elect not to comply with certain corporate governance requirements of the NYSE, including that: (1) a majority of our Board consist of independent directors, (2) our Board have a compensation committee that is comprised entirely of independent directors, (3) our Board have a nominating and corporate governance committee that is comprised entirely of independent directors and (4) our Board conduct an annual performance evaluation of the compensation committee and nominating and corporate governance committee. We currently do not plan to establish a compensation committee or nominating and corporate governance committee composed entirely of independent directors as permitted by these exemptions. Accordingly, you will not have the same protections afforded to stockholders of companies that are subject to all of these corporate governance

requirements. See “Risk Factors—Upon the listing of the Class A common stock on the NYSE, we will be a “controlled company” within the meaning of the NYSE rules and, as a result, will qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You will not have the same protections afforded to stockholders of companies that are subject to such requirements.” In the event that we cease to be a “controlled company” and shares of our Class A common stock continue to be listed on NYSE, we will be required to comply with these provisions within the applicable transition periods.

Committees of the Board of Directors

Our Board intends to establish an audit committee, a nominating and corporate governance committee and a compensation committee prior to the completion of this offering, and we may have such other committees as the Board shall determine from time to time. We anticipate that each of the standing committees of the Board will have the composition and responsibilities described below.

Audit Committee

We will establish an audit committee prior to the completion of this offering. We anticipate that following completion of this offering, our audit committee will consist of Charles Davis, General (RET) James McConville and Mike Stone, each of whom will be independent under SEC rules and NYSE listing standards. As required by the SEC rules and NYSE listing standards, the audit committee will consist solely of independent directors. SEC rules also require that a public company disclose whether its audit committee has an “audit committee financial expert” as a member. An “audit committee financial expert” is defined as a person who, based on his or her experience, possesses the attributes outlined in such rules. We anticipate that at least one of our independent directors will satisfy the definition of “audit committee financial expert.”

This committee will oversee, review, act on and report on various auditing and accounting matters to our Board, including the selection of our independent accountants, the scope of our annual audits, fees to be paid to the independent accountants, the performance of our independent accountants and our accounting practices. In addition, the audit committee will oversee our compliance programs relating to legal and regulatory requirements. We expect to adopt an audit committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and the listing standards of the NYSE.

Nominating and Corporate Governance Committee

We will establish a nominating and corporate governance committee prior to the completion of this offering. We anticipate that the nominating and corporate governance committee will consist of John E. Abele, Kyle Clark and Charles Davis. This committee will identify, evaluate and recommend qualified nominees to serve on our Board; develop and oversee our internal corporate governance processes; and maintain a management succession plan. We expect to adopt a nominating and corporate governance committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and the listing standards of the NYSE.

Compensation Committee

We will establish a compensation committee prior to the completion of this offering. We anticipate that the compensation committee will consist of Charles Davis, Dean L. Kamen and Dr. Martine A. Rothblatt. This committee will also establish salaries, incentives and other forms of compensation for officers and other employees and will administer our incentive compensation and benefit plans. We expect to adopt a compensation committee charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and the listing standards of the NYSE.

Compensation Committee Interlocks and Insider Participation

None of our executive officers serve on the Board or compensation committee of a company that has an executive officer that serves on our Board or compensation committee. No member of our Board is an executive

134

##### Table of Contents

officer of a company in which one of our executive officers serves as a member of the board of directors or compensation committee of that company.

Executive Sessions of Our Board of Directors

Our independent directors are provided the opportunity to meet in executive session at each regularly scheduled meeting of our Board.

Risk Oversight

The Board is actively involved in oversight of risks that could affect us. This oversight function is conducted primarily through committees of our Board, but the full Board retains responsibility for general oversight of risks. The audit committee is charged with oversight of our system of internal controls and risks relating to financial reporting, legal, regulatory and accounting compliance. Our Board will continue to satisfy its oversight responsibility through full reports from the audit committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within our Company.

Code of Business Conduct and Ethics

Prior to the completion of this offering, our Board will adopt a code of business conduct and ethics applicable to our employees, directors and officers, in accordance with applicable U.S. federal securities laws and NYSE corporate governance standards. Any waiver of this code may be made only by our Board and will be promptly disclosed as required by applicable U.S. federal securities laws and NYSE corporate governance standards.

Corporate Governance Guidelines

Prior to the completion of this offering, our Board will adopt corporate governance guidelines in accordance with NYSE corporate governance standards.

EXECUTIVE COMPENSATION

We are an “emerging growth company,” as defined in the JOBS Act, for purposes of the SEC’s executive compensation disclosure rules. In accordance with such rules, we are required to provide a Summary Compensation Table and an Outstanding Equity Awards at Fiscal Year End Table, as well as limited narrative disclosures regarding executive compensation for our last completed fiscal year. Further, our reporting obligations extend only to our “named executive officers,” who are the individuals who served as our principal executive officer and our next two other most highly compensated officers at the end of fiscal year 2024. Accordingly, our “Named Executive Officers” or “NEOs” are:

Name |  | Principal Position
Kyle Clark |  | Chief Executive Officer, President and Director
Sean Donovan |  | Chief Operating Officer(1)
Brian Dunkiel |  | Chief Legal Officer, Vice President and Secretary

(1) | Mr. Donovan was promoted to the role of Chief Operating Officer effective as of September 9, 2024.

Our compensation objectives have been to recruit and retain a talented team of employees to grow and develop our business, and to reward those employees for accomplishments related to our growth and development. Historically, our compensation committee determined the compensation for (i) our Chief Executive Officer based on such factors as it deemed relevant under the circumstances and (ii) the rest of our management team based on the recommendations of our Chief Executive Officer. In setting compensation, our Chief Executive Officer and our compensation committee did not seek to allocate long-term and current compensation, or cash and noncash compensation, in any particular percentage. Instead, they reviewed each element of compensation independently and determined the appropriate amount for each element, as discussed below. We believe that our historical compensation-setting processes have been effective for a privately held company, but we expect our compensation committee to reevaluate our compensation-setting processes following this offering.

Summary Compensation Table

The following table summarizes the compensation awarded to, earned by or paid to our NEOs for the fiscal year ending December 31, 2024.

Name and Principal Position |  | Fiscal Year |  |  | Salary ($) |  |  | Bonus ($)(1) |  |  | Option Awards ($)(2) |  |  | Total ($) |
Kyle Clark Chief Executive Officer & President |  |  | 2024 |  |  |  | 530,000 |  |  |  | 530,000 |  |  |  | — |  |  |  | 1,060,000 |
Sean Donovan Chief Operating Officer |  |  | 2024 |  |  |  | 282,711 |  |  |  | 100,000 |  |  |  | 161,000 |  |  |  | 543,711 |

(1) | The amounts in this column represent a discretionary cash incentive bonus awarded to each of our NEOs in respect of fiscal year 2024.

(2) | The amount reported reflects the grant date fair value of stock options granted in 2024 calculated in accordance with FASB ASC Topic 718. The assumptions used in calculating the grant date fair value of the stock options reported in this column are set forth in Note 9—“Stock Based Compensation” in the Notes to our historical audited consolidated financial statements included elsewhere in this prospectus. The amount reported in this column reflects the aggregate accounting cost for this award, and does not necessarily correspond to the actual economic value that may be received by Mr. Donovan from the stock options.

Actions Taken in Connection with this Offering

Employment Agreements

In connection with this offering, we expect to enter into an employment agreement with each of our NEOs, each of which will provide for standard terms including provision of base salary, opportunity to earn a cash bonus, eligibility to participate in the Company’s health and welfare benefits, and severance protections in the event of certain qualifying terminations.

2025 Omnibus Incentive Plan

In order to incentivize our employees and other service providers following the completion of this offering, we anticipate that our Board will adopt the 2025 Omnibus Incentive Plan (the “2025 Plan”) for eligible employees, consultants, and directors prior to the completion of this offering. Our NEOs will be eligible to participate in the 2025 Plan, which we expect will become effective upon the consummation of this offering. We anticipate that the 2025 Plan will provide for the grant of options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards, and substitute awards intended to align the interests of service providers, including our NEOs, with those of our shareholders.

Securities to be Offered

Subject to adjustment in the event of certain transactions or changes of capitalization in accordance with the 2025 Plan, a number of shares of common stock equal to    % of the number of shares of common stock

139

##### Table of Contents

outstanding at the closing of this offering (on a fully diluted basis) (the “Share Reserve”) will be reserved for issuance pursuant to awards under the 2025 Plan. The total number of shares reserved for issuance under the 2025 Plan will be increased annually on January 1 of each calendar year beginning in 2026 and ending and including January 1, 2035, by the lesser of (i)    % of the aggregate number of shares of common stock, outstanding on December 31 of the immediately preceding calendar year and (ii) the number of shares of common stock as is determined by our board of directors. Shares of common stock subject to an award that expires or is canceled, forfeited, exchanged, settled in cash or otherwise terminated without delivery of shares and shares withheld to pay the exercise price of, or to satisfy the withholding obligations with respect to, an award will again be available for delivery pursuant to other awards under the 2025 Plan.

Administration

The 2025 Plan will be administered by a committee of our board of directors (the “Committee”), except to the extent our board of directors does not duly authorize such Committee to administer the 2025 Plan and in which case our board of directors will serve as the administrator. The Committee has broad discretion to administer the 2025 Plan, including the power to determine the eligible individuals to whom awards will be granted, the number and type of awards to be granted and the terms and conditions of awards. The Committee may also accelerate the vesting or exercise of any award and make all other determinations and to take all other actions necessary or advisable for the administration of the 2025 Plan. To the extent the 2025 Plan administrator is not the Committee, our board of directors will retain the authority to take all actions permitted by the administrator under the 2025 Plan. Additionally, our board of directors retains the right to exercise the authority of the Committee to the extent consistent with applicable law.

Eligibility

Our employees, consultants and non-employee directors, and employees and consultants of our affiliates, will be eligible to receive awards under the 2025 Plan.

Non-Employee Director Compensation Limits

Under the 2025 Plan, in a single calendar year, a non-employee director may not be granted awards for such individual’s service on our board of directors having a value, taken together with any cash fees paid to such non-employee director, in excess of $750,000 (except that for any year in which a non-employee director (i) first commences service on our board of directors, (ii) serves on a special committee of our board of directors or (iii) serves as lead director or non-executive chair of our board of directors, such limit will be increased to $1,000,000). Such limits will not be applied to awards or other compensation, if any, provided to a non-employee director during any period in which such individual was an employee of the Company or any Affiliate or was otherwise providing services to the Company or to any Affiliate other than in the capacity as a non-employee director.

Types of Awards

Stock Options. We may grant stock options to eligible persons, except that incentive stock options may only be granted to persons who are our employees or employees of one of our subsidiaries, in accordance with Section 422 of the Code. The exercise price of a stock option generally cannot be less than 100% of the fair market value of a share of common stock on the date on which the stock option is granted and the stock option must not be exercisable for longer than 10 years following the date of grant. In the case of an incentive stock option granted to an individual who owns (or is deemed to own) at least 10% of the total combined voting power of all classes of our equity securities, the exercise price of the option must be at least 110% of the fair market value of a share of common stock on the date of grant and the option must not be exercisable more than five years from the date of grant.

140

##### Table of Contents

Stock Appreciation Rights. A stock appreciation right (“SAR”) is the right to receive an amount equal to the excess of the fair market value of one share of common stock on the date of exercise over the grant price of the SAR. The grant price of a SAR generally cannot be less than 100% of the fair market value of a share of common stock on the date on which the SAR is granted. The term of a SAR may not exceed 10 years. SARs may be granted in connection with, or independent of, other awards. The Committee has the discretion to determine other terms and conditions of a SAR award.

Restricted Stock Awards. A restricted stock award is a grant of shares of common stock subject to the restrictions on transferability and risk of forfeiture imposed by the Committee. Unless otherwise determined by the Committee and specified in the applicable award agreement, the holder of a restricted stock award has rights as a stockholder, including the right to vote the shares of common stock subject to the restricted stock award or to receive dividends on the shares of common stock subject to the restricted stock award during the restriction period. In the discretion of the Committee or as set forth in the applicable award agreement, dividends distributed prior to vesting may be subject to the same restrictions and risk of forfeiture as the restricted stock with respect to which the distribution was made.

Restricted Stock Units. A restricted stock unit is a right to receive cash, shares of common stock or a combination of cash and shares of common stock at the end of a specified period equal to the fair market value of one share of common stock on the date of vesting. Restricted stock units may be subject to the restrictions, including on transferability and forfeitability, imposed by the Committee. If the Committee so provides, a grant of restricted stock units may provide a participant with the right to receive dividend equivalents.

Performance Awards. A performance award is an award that vests and/or becomes exercisable or distributable subject to the achievement of certain performance goals during a specified performance period, as established by the Committee. Performance awards (which include performance stock units) may be granted alone or in addition to other awards under the 2025 Plan, and may be paid in cash, shares of common stock, other property or any combination thereof, in the sole discretion of the Committee.

Stock Awards. A stock award is a transfer of unrestricted shares of common stock on terms and conditions, if any, determined by the Committee.

Dividend Equivalents. Dividend equivalents entitle a participant to receive cash, shares of common stock, other awards or other property equal in value to dividends or other distributions paid with respect to a specified number of shares of common stock. Dividend equivalents may be granted on a free-standing basis or in connection with another award (other than stock options, SARs, restricted stock or stock awards).

Other Stock-Based Awards. Other stock-based awards are awards denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, the value of our shares of common stock. Cash Awards. Cash awards may be granted on terms and conditions, including vesting conditions, and for consideration, including no consideration or minimum consideration as required by applicable law, as the Committee determines in its sole discretion.

Substitute Awards. In connection with an entity’s merger or consolidation with the Company or the Company’s acquisition of an entity’s property or stock, awards may be granted in substitution for any other award granted before the merger or consolidation by such entity or its affiliates.

Certain Transactions

If any change is made to our capitalization, such as a share split, share combination, share dividend, exchange of shares or other recapitalization, merger or otherwise, that results in an increase or decrease in the number of outstanding shares of common stock, appropriate adjustments will be made by the Committee in the shares subject to an award under the 2025 Plan. The Committee will also have the discretion to make certain

141

##### Table of Contents

adjustments to awards in the event of a change in control, such as accelerating the vesting or exercisability of awards, requiring the surrender of an award, with or without consideration, or making any other adjustment or modification to the award that the Committee determines is appropriate in light of such transaction.

Clawback

All awards granted under the 2025 Plan will be subject to clawback, cancellation, recoupment, rescission, payback, reduction, or other similar action in accordance with any Company clawback or similar policy or any applicable law related to such actions.

Plan Amendment and Termination

Our board of directors or the Committee may amend or terminate any award, award agreement or the 2025 Plan at any time; however, stockholder approval will be required for any amendment to the extent necessary to comply with applicable law. Stockholder approval will be required to make amendments that (i) increase the aggregate number of shares that may be issued under the 2025 Plan or (ii) change the classification of individuals eligible to receive awards under the 2025 Plan. The 2025 Plan will remain in effect for a period of 10 years (unless earlier terminated by our board of directors).

IPO Grants

In connection with this offering, we expect to grant time-vesting restricted stock units under the 2025 Plan to certain employees (collectively, the “IPO Grants”), assuming an initial public offering price of $ per share, the midpoint of the estimated price range set forth on the cover page of this prospectus, with the actual number of restricted stock units and stock options to be determined at the pricing of this offering. None of our NEOs are expected to receive an IPO Grant.

Employee Stock Purchase Plan

In order to incentivize employees of the Company, its designated affiliates and subsidiaries (the “Designated Subsidiaries”), we anticipate that our board of directors will adopt, and our shareholders will approve, the BETA Technologies, Inc. 2025 Employee Stock Purchase Plan (the “ESPP”), the material terms of which are summarized below, prior to the completion of this offering. The ESPP is comprised of two distinct components in order to provide increased flexibility to grant rights to purchase shares under the ESPP that are intended to qualify for favorable U.S. federal tax treatment under Section 423 of the Code (the “Section 423 Component”) and rights to purchase shares that are not intended to be tax-qualified under Section 423 of the Code. Although not yet adopted, we expect that the ESPP will have the features described below.

Shares Available for Awards; Administration

A total number of shares of common stock equal to    % of the number of shares of common stock outstanding at the closing of this offering (on a fully diluted basis) will initially be reserved for issuance under the ESPP. In addition, the number of shares available for issuance under the ESPP will be increased annually on January 1 of each calendar year beginning in 2026 and ending and including January 1, 2035, by an amount equal to the lesser of (i)    % of the shares outstanding on December 31 of the immediately preceding calendar year or (ii) such smaller number of shares as determined by our board of directors. Our compensation committee or other individuals to which authority has been delegated under the ESPP will administer and will have authority to interpret the terms of the ESPP and determine eligibility of participants. The entity that conducts the general administration of this ESPP (which is our compensation committee unless the board of directors assumes the authority for administration) is referred to herein as the “plan administrator.”

142

##### Table of Contents

Eligibility

We expect that all of our employees and employees of any Designated Subsidiary will be eligible to participate in the ESPP, with certain exclusions as determined by the plan administrator. However, an employee may not be granted rights to purchase stock under the ESPP if the employee, immediately after the grant, would own (directly or through attribution) stock possessing 5% or more of the total combined voting power of all classes of our stock.

Grant of Rights

Under the ESPP, participants will be offered the right to purchase shares of our common stock at a discount during one or more offering periods, which may be successive or overlapping and will be selected by the plan administrator in its sole discretion with respect to which rights will be granted to participants. The plan administrator will designate the terms and conditions of each offering in writing, including the offering period, and may change the duration and timing of offering periods in its discretion. However, in no event may an offering period be longer than 27 months in length.

Unless otherwise set forth in the ESPP or in an offering document, a participant may participate in the ESPP only by means of payroll deductions of up to a specified percentage of their eligible compensation. In non-U.S. jurisdictions where participation in the ESPP through payroll deductions is prohibited, the plan administrator may provide that an eligible employee may elect to participate through contributions to the participant’s account under the ESPP in a form acceptable to the plan administrator in lieu of or in addition to payroll deductions. The plan administrator will establish a maximum number of shares that may be purchased by a participant during any purchase period or offering period (which, in the absence of a contrary designation by the administrator, will be    shares). In addition, no employee will be permitted to accrue the right to purchase stock under the Section 423 Component at a rate in excess of $25,000 worth of shares during any calendar year during which such a purchase right is outstanding (based on the fair market value per share of our common stock as of the first day of the offering period).

On the first trading day of each offering period, each participant will automatically be granted the right to purchase shares of our common stock. The right will expire at the end of the applicable offering period and will be exercised on each applicable purchase date during an offering period to the extent of the payroll deductions accumulated during the applicable purchase period. Participants may voluntarily end their participation in the ESPP at any time during a specified period prior to the end of the applicable offering period and will be paid their accrued payroll deductions that have not yet been used to purchase shares of common stock.

A participant may not transfer rights granted under the ESPP other than by will or the laws of descent and distribution, and such rights are generally exercisable only by the participant.

Purchase Price

The purchase price will be designated by the plan administrator, but, with respect to the Section 423 Component, will not be less than 85% of the fair market value of a share of our common stock on the applicable enrollment date or the applicable exercise date, whichever is lower.

Certain Transactions

In the event of certain transactions or events affecting our common stock, the plan administrator will make equitable adjustments to the ESPP and outstanding rights. In the event of certain unusual or non-recurring transactions or events, the plan administrator may provide for (i) either the termination of outstanding rights in exchange for cash or the replacement of outstanding rights with other rights or property, (ii) the assumption or substitution of outstanding rights by the successor or survivor corporation, or a parent or subsidiary thereof, (iii)

143

##### Table of Contents

the adjustment in the number and type of shares of stock subject to outstanding rights, (iv) the use of participants’ accumulated payroll deductions to purchase stock on a new purchase date prior to the next scheduled purchase date and termination of any rights under ongoing offering periods, or (v) the termination of all outstanding rights.

ESPP Amendment and Termination

The plan administrator may amend, suspend or terminate the ESPP at any time. However, shareholder approval will be required for any amendment that (i) increases the aggregate number or changes the type of shares subject to the ESPP or (ii) changes the ESPP in any manner that would be considered the adoption of a new plan within the meaning of Treasury Regulation § 1.423-2(c)(4). In the event that the plan administrator determines that the ongoing operation of the ESPP may result in unfavorable financial accounting consequences, the administrator may modify or amend the ESPP to reduce or eliminate those consequences. Upon termination of the ESPP, the balance in each participant’s plan account will be refunded as soon as practicable.

DESCRIPTION OF CAPITAL STOCK

General

We expect to file our Amended and Restated Certificate of Incorporation and adopt our Amended and Restated Bylaws, which, in each case, will occur after the effectiveness of this registration statement and become effective immediately prior to the completion of this offering. Our Amended and Restated Certificate of Incorporation will authorize capital stock consisting of:

| • |  | shares of common stock, par value $0.0001 per share, of which      shares will be designated as Class A common stock, $0.0001 par value per share, and      shares will be designated as Class B common stock, $0.0001 par value per share; and

| • |  | shares of preferred stock, par value $0.0001 per share.

We are selling      shares of our Class A common stock in this offering (     shares if the underwriters exercise their overallotment option to purchase additional shares of our Class A common stock in full).

After giving effect to (i) the conversion of all outstanding shares of our Preferred Stock into an aggregate    shares of Common Stock and the subsequent cancellation of such shares of Preferred Stock, which, in each case, will occur prior to the completion of this offering (the “Preferred Stock Recapitalization”), (ii) the filing and effectiveness of our Amended and Restated Certificate of Incorporation, pursuant to which all outstanding shares of Common Stock will be reclassified into Class A common stock (the “Common Stock Reclassification”) and a     -for-1 forward split of our capital stock will be effected, and the adoption of our Amended and Restated Bylaws, each of which will occur after the effectiveness of this registration statement and prior to the completion of this offering and (iii) the exchange of an aggregate of     shares of Super Voting Common Stock beneficially owned by the Class B Common Stockholder for an equivalent number of shares of our Class B common stock, to be effected in connection with the closing of this offering pursuant to the terms of an exchange and forfeiture agreement entered into with us (the “Class B Stock Exchange” and, collectively with the Preferred Stock Recapitalization and the Common Stock Reclassification, the “IPO Recapitalization”), as of     , 2025, there were      shares of our Class A common stock outstanding, held by     stockholders of record,      shares of our Class B common stock outstanding, held by one stockholder of record, and no shares of our preferred stock outstanding.

Below is a summary of the material terms and provisions of our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, the Amended and Restated Investors’ Rights Agreement and relevant provisions of Delaware law affecting the rights of our stockholders. This summary does not purport to be complete and is qualified in its entirety by the provisions of our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and the Amended and Restated Investors’ Rights Agreement, copies of which are filed as exhibits to the registration statement of which this prospectus forms a part, and to the applicable provisions of Delaware law.

Common Stock

Voting Rights

Holders of shares of our Class A common stock will be entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Holders of our Class B common stock are entitled to 40 votes per share on any matter submitted to our stockholders. Holders of shares of Class A common stock and Class B common stock will vote together as a single class on all matters (including the election of directors) submitted to a vote of stockholders, unless otherwise required by Delaware law or our Amended and Restated Certificate of Incorporation that becomes effective immediately prior to the completion of this offering.

Under Delaware law, holders of our Class A common stock or Class B common stock would be entitled to vote as a separate class if a proposed amendment to our Amended and Restated Certificate of Incorporation

153

##### Table of Contents

would increase or decrease the aggregate number of authorized shares of such class, increase or decrease the par value of the shares of such class, or alter or change the powers, preferences, or special rights of the shares of such class so as to affect them adversely. As a result, in these limited instances, the holders of a majority of the Class A common stock could defeat any amendment to our Amended and Restated Certificate of Incorporation. For example, if a proposed amendment of our Amended and Restated Certificate of Incorporation provided for the Class A common stock to rank junior to the Class B common stock with respect to (1) any dividend or distribution, (2) the distribution of proceeds were we to be acquired or (3) any other right, Delaware law would require the vote of the Class A common stock. In this instance, the holders of a majority of Class A common stock could defeat that amendment to our Amended and Restated Certificate of Incorporation.

Our Amended and Restated Certificate of Incorporation, which will come into effect immediately prior to the closing of this offering, will not provide for cumulative voting for the election of directors.

Dividends

Holders of the shares of our Class A common stock and Class B common stock will be entitled to receive ratably those dividends, if any, as may be declared by our Board out of funds legally available therefor, subject to any statutory or contractual restrictions on the payment of dividends and to any restrictions on the payment of dividends imposed by the terms of any outstanding preferred stock.

Liquidation

In the event of our dissolution or liquidation, after payment in full of all amounts required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of shares of our Class A common stock will be entitled to share ratably in the remaining assets legally available for distribution.

Holders of our Class A common stock and Class B common stock are not entitled to preemptive rights and are not subject to subscription, conversion, redemption or sinking fund provisions, except for the conversion provisions with respect to the Class B common stock described below. There will be no redemption or sinking fund provisions applicable to our Class A common stock or Class B common stock. The rights, preferences and privileges of the holders of our Class A common stock and Class B common stock will be subject to and may be adversely affected by the rights of the holders of shares of any series of our preferred stock that we may designate in the future.

Conversion

Each outstanding share of our Class B common stock is convertible at any time at the option of the holder into one share of our Class A common stock. In addition, each share of our Class B common stock will convert automatically into one share of our Class A common stock upon any transfer, whether or not for value, which occurs after the closing of this offering, except for certain permitted transfers described in our Amended and Restated Certificate of Incorporation, including transfers to immediate family members (including upon the Class B Common Stockholder’s death), trusts (including grantor retained annuity trusts) for which the stockholder or their immediate family member serves as trustee and partnerships, corporations and other entities exclusively owned by the Class B Common Stockholder or his immediate family. All of the outstanding shares of Class B common stock will convert automatically into shares of Class A common stock upon the earliest to occur following this offering: (i) the date that is fixed by our Board that is no less than      days and no more than      days following the date the Class B Common Stockholder is no longer providing services to us as an executive officer or member of our Board and (ii) a date that is fixed by our Board that is no less than      days and no more than      days following the death or incapacity of the Class B Common Stockholder. Once converted or transferred and converted into our Class A common stock, the Class B common stock will not be reissued.

Fully Paid and Nonassessable

All shares of our Class A common stock outstanding upon consummation of this offering will be fully paid and non-assessable.

Preferred Stock

Pursuant to the provisions of our Amended and Restated Certificate of Incorporation, that will occur after the effectiveness of this registration statement and become effective immediately prior to the consummate of this offering, each currently outstanding share of our Preferred Stock will automatically be converted into one share of our Class A common stock. Following this offering, no shares of preferred stock will be outstanding.

Following the completion of this offering, our Board will be authorized to direct us to issue shares of preferred stock in one or more series without shareholder approval. Our Board has the discretion to determine the rights, powers, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, of each series of preferred stock.

The purpose of authorizing our Board to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a shareholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings and other corporate purposes, could have the effect of making it more difficult for a third-party to acquire, or could discourage a third-party from seeking to acquire, a majority of our outstanding voting stock. Additionally, the issuance of preferred stock may adversely affect the holders of our Class A common stock by restricting dividends on the Class A common stock, diluting the voting power of the common stock or subordinating the liquidation rights of the common stock. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of our Class A common stock.

Warrants

Following this offering, we will have one series of outstanding warrants. Following this offering and the IPO Recapitalization, the warrants will be exercisable for     of Class A common stock at an exercise price of $0.01 per share.

The warrants are exercisable upon vesting, and vest subject to the satisfaction of certain milestones related to the Strategic Collaboration Agreement and Joint Technology Development Agreement with GE Aerospace, with any shares that remain unvested on the third anniversary of issuing the warrant vesting on such date if we and GE Aerospace are continuing to work together under such agreements (or a similar arrangement) as of such date.

Anti-Takeover Effects of Provisions of Our Charter, Our Bylaws and Delaware Law

Some provisions of Delaware law, our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws could make certain change of control transactions more difficult, including acquisitions of us by means of a tender offer, a proxy contest or otherwise, as well as removal of our incumbent officers and directors. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares. Therefore, these provisions could adversely affect the price of our common stock.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our Board. We believe that the benefits of increased protection and our potential ability to negotiate with the proponent of an unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because, among other things, negotiation of these proposals could result in an improvement of their terms.

155

##### Table of Contents

Our Charter and Bylaws

Among other things, our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws:

| • |  | establish advance notice procedures with regard to stockholder proposals relating to the nomination of candidates for election as directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the preceding year’s annual meeting. Our Amended and Restated Bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may deter stockholders from bringing matters before the stockholders at an annual or special meeting;

| • |  | authorize our Board to issue undesignated preferred stock. This ability makes it possible for our Board to issue, without stockholder approval, preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes in control or management of our company;

| • |  | provide that the authorized number of directors may be changed only by resolution of the Board;

| • |  | provide that all vacancies, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a series of preferred stock, be filled by the affirmative vote of a majority of the total number of directors then in office, even if less than a quorum;

| • |  | provide that special meetings of our stockholders may only be called by a majority of the total number of directors;

| • |  | provide that our Board be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three-year terms, other than directors which may be elected by holders of preferred stock, if any. This system of electing and removing directors may tend to discourage a third party from making a tender offer or otherwise attempting to obtain control of us because it generally makes it more difficult for stockholders to replace a majority of the directors;

| • |  | provide that our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws may be amended by the affirmative vote of the holders of at least two-thirds of our then outstanding common stock (except with respect to provisions relating to the renouncement business opportunities, which require approval of at least 80% of the voting power of the outstanding stock entitled to vote thereon); and

| • |  | provide that a member of our Board may only be removed for cause and only by the affirmative vote of the holders of at least two-thirds of our then outstanding common stock.

Forum Selection

Our Amended and Restated Certificate of Incorporation provides that unless we consent to the selection of an alternative forum, the Delaware Court of Chancery shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a duty (including any fiduciary duty) owed by any of our directors, officers, employees, agents or stockholders to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws, (iv) any action to interpret, apply, enforce or determine the validity of our Amended and Restated Certificate of Incorporation or our Amended and Restated Bylaws, (v) any action asserting a claim against us or any of our directors, officers, employees, agents or stockholders that is governed by the internal affairs doctrine, (vi) any action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL or (vii) any action as to which the DGCL confers jurisdiction on the Delaware Court of Chancery; provided that, for the

156

##### Table of Contents

avoidance of doubt, the forum selection provision that identifies the Delaware Court of Chancery as the exclusive forum for certain litigation, including any “derivative action,” will not apply to suits to enforce a duty or liability created by the Securities Act or the Exchange Act. Our Amended and Restated Certificate of Incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act or the Exchange Act. However, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder; accordingly, we cannot be certain that a court would enforce such provision. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of our Company shall be deemed to have notice of and consented to the forum provisions in our Amended and Restated Certificate of Incorporation. However, our stockholders will not be deemed to have waived (and cannot waive) compliance with the federal securities laws and the rules and regulations thereunder. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law or the Securities Act, as applicable, for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors, officers, employees or agents. Alternatively, if a court were to find any of the forum selection provisions contained in our Amended and Restated Certificate of Incorporation to be inapplicable or unenforceable, we may incur additional costs associated with having to litigate such action in other jurisdictions, which could have an adverse effect on our business, financial condition, results of operations, cash flows and prospects and result in a diversion of the time and resources of our employees, management and our Board.

Limitation of Liability and Indemnification of Officers and Directors

Our directors will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except, if required by Delaware law, for liability:

| • |  | for any breach of the duty of loyalty to us or our stockholders;

| • |  | for acts or omissions not in good faith or involving intentional misconduct or a knowing violation of law;

| • |  | for unlawful payment of a dividend or unlawful stock purchases or redemptions; or

| • |  | for any transaction from which the director derived an improper personal benefit.

As a result, neither we nor our stockholders have the right, through stockholders’ derivative suits on our behalf, to recover monetary damages against a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior, except in the situations described above. We intend to enter into indemnification agreements with each of our current and future directors and officers.

Director Designation Right

Our Amended and Restated Certificate of Incorporation will provide GE Aerospace with the right to designate one individual for election to our Board (the “Director Designation Right”) for so long as either (i) GE Aerospace beneficially owns at least     shares of Class A common stock (which is equivalent to 33% of the Series C-1 Preferred Stock it beneficially owned as of September  , 2025) or (ii) there is a Commercial Relationship (as defined in the GE Aerospace Letter Agreement). GE Aerospace held 2,620,774 shares of Series C-1 Preferred Stock at the time immediately prior to the IPO Recapitalization. At any time when GE Aerospace has neither the minimum ownership threshold nor the Commercial Relationship requirement, the Director Designation Right will terminate.

We will be required to take all necessary actions to include GE Aerospace nominee in the slate of director nominees recommended by our Board for election by our stockholders, to solicit proxies in favor of the election of such nominee in the same manner as for other Board-recommended nominees, and to fill any vacancies

157

##### Table of Contents

created by the departure of GE Aerospace’s nominee with a new nominee selected by GE Aerospace, subject to applicable law and stock exchange requirements. We will also refrain from amending our charter or bylaws in a manner that would materially and adversely affect these rights. Additionally, if the GE Aerospace-designated director is unable to attend a meeting of the Board, GE Aerospace may appoint a non-voting alternate to attend and observe the meeting.

In addition, pursuant to the Voting Agreement, Kyle Clark, our founder and Chief Executive Officer, has agreed to vote all his shares of the Company’s capital stock entitled to vote and held by him in favor of the director designated pursuant to GE Aerospace’s Director Designation Right at any meeting of the stockholders of the Company and in any written consent of stockholders and in favor of not removing such director without GE Aerospace’s affirmative consent. See “Certain Relationships and Related Party Transactions—Voting Rights Letter Agreement” for additional information related to such agreement.

Registration Rights

The Amended and Restated Investors’ Rights Agreement grants certain holders of our Class A common stock registration rights, whereby, we will agree to register the sale of shares of our Class A common stock held by holders of our Preferred Stock under certain circumstances, and to provide such stockholders with certain customary underwritten offering, block trade and piggyback rights. For additional information relating to our Class A common stock, please read “Certain Relationships and Related Party Transactions—Amended and Restated Investors’ Rights Agreement.”

Transfer Agent and Registrar

The transfer agent and registrar for the common stock is Computershare Trust Company, N.A.

Listing; Public Market

We have applied, subject to official notice of issuance, to list our Class A common stock on the NYSE under the symbol “BETA.” There is no established market for our shares of Class A common stock. The development and maintenance of a public market for our Class A common stock, having the desirable characteristics of depth, liquidity and orderliness, depends on the existence of willing buyers and sellers, the presence of which is not within our control or that of any market maker. The number of active buyers and sellers of shares of our Class A common stock at any particular time may be limited, which may have an adverse effect on the price at which shares of our Class A common stock can be sold.

##### Table of Contents

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the acquisition and holding of shares of Class A common stock by (a) employee benefit plans that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (b) plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under other federal, state, local, non-U.S. or other laws or regulations that are similar to Title I of ERISA or Section 4975 of the Code (collectively, “Similar Laws”), and (c) entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

This summary is based on the provisions of ERISA and Section 4975 of the Code (and related regulations and administrative and judicial interpretations) as of the date of this registration statement. This summary does not purport to be complete, and no assurance can be given that future legislation, court decisions, regulations, rulings or pronouncements will not significantly modify the requirements summarized below. Any of these changes may be retroactive and may thereby apply to transactions entered into prior to the date of their enactment or release. This discussion is general in nature and is not intended to be all inclusive, nor should it be construed as investment or legal advice.

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and Section 4975 of the Code, any person who exercises any discretionary authority or control over the administration of an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation (direct or indirect) to an ERISA Plan, is generally considered to be a fiduciary of such ERISA Plan.

In considering an investment in shares of Class A common stock with the assets of any Plan, a fiduciary should consider the Plan’s particular circumstances and all of the facts and circumstances of the investment and determine whether the acquisition and holding of shares of Class A common stock is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code, or any Similar Laws relating to the fiduciary’s duties to the Plan, including, without limitation:

| • |  | whether the investment is prudent under Section 404(a)(1)(B) of ERISA and any other applicable Similar Laws;

| • |  | whether, in making the investment, the ERISA Plan will satisfy the diversification requirements of Section 404(a)(1)(C) of ERISA and any other applicable Similar Laws;

| • |  | whether the investment is permitted under the terms of the applicable documents governing the Plan;

| • |  | whether the acquisition or holding of the shares of Class A common stock will constitute a “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code (please see discussion under “—Prohibited Transaction Issues” below); and

| • |  | whether the Plan will be considered to hold, as plan assets, (i) only shares of Class A common stock or (ii) an undivided interest in our underlying assets (please see the discussion under “—Plan Asset Issues” below).

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of

159

##### Table of Contents

ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such a non-exempt prohibited transaction may be subject to excise taxes, penalties and liabilities under ERISA and the Code. The acquisition and/or holding of shares of Class A common stock by an ERISA Plan with respect to which the issuer is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction in violation Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption.

In this regard, the U.S. Department of Labor (the “DOL”) has issued prohibited transaction class exemptions (as may be amended from time to time), or “PTCEs,” that may apply to the purchase and holding of shares of Class A common stock. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide a statutory exemption for certain transactions between an ERISA Plan and a person that is a party in interest and/or a disqualified person (other than a fiduciary or an affiliate that, directly or indirectly, has or exercises discretionary authority or control or renders investment advice with respect to the assets involved in the transaction) solely by reason of providing services to the ERISA Plan or by relationship to a service provider. Each of the above-noted exemptions contains conditions and limitations on its application. Fiduciaries of ERISA Plans considering purchasing and/or holding shares of Class A common stock in reliance of these or any other exemption should carefully review the exemption to assure it is applicable. There can be no assurance that all of the conditions of any exemption will be satisfied or that any such exemption would cover all potential prohibited transactions that may be involved in the purchase and holding of shares of Class A common stock.

U.S. governmental plans, while not subject to the fiduciary responsibility provisions of ERISA or the prohibited transaction provisions of ERISA or Section 4975 of the Code, may nevertheless be subject to Similar Laws. Fiduciaries of any such plans should consult with their counsel before purchasing the notes to determine the suitability of shares of Class A common stock for such plan and the availability, if necessary, of any exemptive relief under any such laws or regulations.

Because of the foregoing, shares of Class A common stock should not be acquired or held by any person investing “plan assets” of any Plan, unless such acquisition and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or a violation of any applicable Similar Laws.

Plan Asset Issues

Additionally, a fiduciary of an ERISA Plan should consider whether the ERISA Plan will, by investing in us, be deemed to own an undivided interest in our assets, with the result that we would become a fiduciary of the ERISA Plan and our operations would be subject to the regulatory restrictions of ERISA, including its prohibited transaction rules, as well as the prohibited transaction rules of the Code.

The DOL regulations issued at 29 C.F.R. Section 2510.3-101, as modified by Section 3(42) of ERISA (the “DOL Regulations”), provide guidance with respect to whether the assets of an entity in which ERISA Plans acquire equity interests would be deemed “plan assets” under some circumstances. Under these regulations, an entity’s assets generally would not be considered to be “plan assets” if, among other things:

| • |  | the equity interests acquired by ERISA Plans are “publicly offered securities” (as defined in the DOL Regulations)—i.e., the equity interests are part of a class of securities that is widely held by 100 or more investors independent of the issuer and each other, are freely transferable and are either registered under certain provisions of the federal securities laws or sold to the ERISA Plan as part of a public offering under certain conditions;

160

##### Table of Contents

| • |  | the entity is an “operating company” (as defined in the DOL Regulations)—i.e., it is primarily engaged in the production or sale of a product or service, other than the investment of capital, either directly or through a majority-owned subsidiary or subsidiaries; or

| • |  | there is no significant investment by “benefit plan investors” (as defined in the DOL Regulations)—i.e., immediately after the most recent acquisition by an ERISA Plan of any equity interest in the entity, less than 25% of the total value of each class of equity interest (disregarding certain interests held by persons (other than benefit plan investors) with discretionary authority or control over the assets of the entity or who provide investment advice for a fee (direct or indirect) with respect to such assets, and any affiliates thereof) is held by ERISA Plans.

Due to the complexity of these rules and the excise taxes, penalties and liabilities that may be imposed upon persons involved in non-exempt prohibited transactions or violations of Similar Law, it is particularly important that fiduciaries, or other persons considering acquiring and/or holding shares of our Class A common stock on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the acquisition and holding of shares of Class A common stock. Purchasers of shares of Class A common stock have the exclusive responsibility for ensuring that their acquisition and holding of shares of Class A common stock complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA, the Code or applicable Similar Laws. The sale of shares of Class A common stock to a Plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by any such Plan or that such investment is appropriate for any such Plan.

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has been no public market for our Class A common stock. Future sales of our Class A common stock in the public market, or the availability of such shares for sale in the public market, could adversely affect market prices prevailing from time to time. As described below, only a limited number of shares will be available for sale shortly after this offering due to contractual and legal restrictions on resale. Furthermore, the majority of shares outstanding prior to the consummation of this offering will be subject to the contractual and legal restrictions on resale described below. Nevertheless, sales of a substantial number of shares of our Class A common stock in the public market after such restrictions lapse, or the perception that those sales may occur, could adversely affect the prevailing market price at such time and our ability to raise equity-related capital at a time and price we deem appropriate.

Sales of Restricted Shares

Upon the closing of this offering, we will have outstanding an aggregate of      shares of common stock, assuming no exercise of outstanding options and assuming that the underwriters have not exercised their option to purchase additional share. Of these shares, all of the      shares of Class A common stock to be sold in this offering will be freely tradable without restriction or further registration under the Securities Act, unless the shares are held by any of our “affiliates” as such term is defined in Rule 144 of the Securities Act. All remaining shares of Class A common stock and Class B common stock held by existing stockholders will be deemed “restricted securities” as such term is defined under Rule 144, and the sale of those shares will be subject to the limitations and restrictions that are described below. The restricted securities were, or will be, issued and sold by us in private transactions and are eligible for public sale only if registered under the Securities Act or if they qualify for an exemption from registration under Rule 144 or Rule 701 under the Securities Act, which rules are summarized below. Shares of our Class A common stock that are not restricted securities and are purchased by our affiliates will be “control securities” under Rule 144. Control securities may be sold in the public market subject to the restrictions set forth in Rule 144, other than the holding period requirement.

Upon the expiration (or waiver) of the lock-up agreements described below and the lock-up provisions contained in our existing Amended and Restated Investors’ Rights Agreement and the provisions of Rule 144 and Rule 701 under the Securities Act, the shares of our Class A common stock (excluding the shares to be sold in this offering) that will be available for sale in the public market are as follows:

| • |  | shares will be eligible for sale upon the expiration of the lock-up agreements, beginning 180 days after the date of this prospectus and when permitted under Rule 144 or Rule 701; and

| • |  | shares will be eligible for sale, upon exercise of vested options, upon the expiration of the lock-up agreements, beginning 180 days after the date of this prospectus.

Lock-up Agreements

In connection with this offering, we and all directors and executive officers and the holders of substantially all of our outstanding stock and stock options have agreed that, without the prior written consent of Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC on behalf of the underwriters, we and they will not, and will not publicly disclose an intention to, dispose of or hedge any shares of our Class A common stock or securities convertible into or exchangeable for shares of our Class A common stock during the period ending 180 days after the date of this prospectus, subject to certain exceptions. This lock-up provision applies to Class A common stock and to securities convertible into or exchangeable or exercisable for or repayable with Class A common stock. It also applies to Class A common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition. See “Underwriting” for a description of these lock-up provisions.

Rule 144

In general, under Rule 144 as currently in effect, once we have been a reporting company subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act for 90 days, a person (or persons whose

162

##### Table of Contents

shares are aggregated) who is not deemed to have been an affiliate of ours at any time during the three months preceding a sale, and who has beneficially owned restricted securities within the meaning of Rule 144 for at least six months (including any period of consecutive ownership of preceding non-affiliated holders), would be entitled to sell those shares, subject only to the availability of current public information about us. A non-affiliated person who has beneficially owned restricted securities within the meaning of Rule 144 for at least one year would be entitled to sell those shares without regard to the provisions of Rule 144.

Once we have been a reporting company subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act for 90 days and have filed all required reporting during that time period, a person (or persons whose shares are aggregated) who is deemed to be an affiliate of ours and who has beneficially owned restricted securities within the meaning of Rule 144 for at least six months would be entitled to sell within any three-month period a number of shares that does not exceed the greater of (a) 1% of the then outstanding shares of our common stock or (b) the average weekly trading volume of our Class A common stock reported through the      during the four calendar weeks preceding the filing of a notice on Form 144 with respect to that sale. Such sales are also subject to certain manner of sale provisions, notice requirements and the availability of current public information about us. An “affiliate” is a person that directly, or indirectly through one or more intermediaries, controls or is controlled by, or is under common control with an issuer.

Rule 701

In general, under Rule 701 as in effect on the date of this prospectus, any of our employees, directors, officers, consultants or advisors who purchases shares from us in connection with a compensatory stock or option plan or other written agreement pursuant to Rule 701 before the effective date of the registration statement for this offering, or who purchased shares from us after that date upon the exercise of options granted before that date, is entitled to sell such shares 90 days after the effective date of this offering in reliance on Rule 144. If such person is not an affiliate, such sale may be made subject only to the manner of sale provisions of Rule 144. If such a person is an affiliate, such sale may be made under Rule 144 without compliance with the holding period requirement, but subject to the other Rule 144 restrictions described above. However, substantially all Rule 701 shares are subject to lock-up agreements as described above and will become eligible for sale in compliance with Rule 144 only upon the expiration of the restrictions set forth in those agreements. The SEC has indicated that Rule 701 will apply to typical stock options granted by an issuer before it becomes subject to the reporting requirements of the Exchange Act, along with the shares acquired upon exercise of such options, including exercises after the date of this prospectus.

S-8 Registration Statement

We intend to file a registration statement on Form S-8 under the Securities Act covering shares of Class A common stock reserved for issuance under our LTIP (including shares issuable pursuant to equity award grants made under the BETA Plan prior to this offering, to the extent such awards remain outstanding after this offering). Such registration statement is expected to be filed as soon as practicable after the closing date of this offering. Shares of Class A common stock issued pursuant to equity awards after the effective date of the applicable Form S-8 registration statement will be eligible for resale in the public market without restriction, subject to Rule 144 limitations applicable to affiliates and the lock-up agreements described above.

Registration Rights

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a summary of the material U.S. federal income tax considerations related to the purchase, ownership and disposition of our Class A common stock by a non-U.S. holder (as defined below), that holds our Class A common stock as a “capital asset” (generally property held for investment), but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based on the provisions of the Code, U.S. Treasury regulations, administrative rulings and judicial decisions, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect. We cannot assure you that a change in law will not significantly alter the tax considerations that we describe in this summary. We have not sought any ruling from the Internal Revenue Service (“IRS”) with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, this summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any state, local or non-U.S. tax laws, the application or impact of any tax treaties or the base erosion and anti-abuse tax, or the requirements of Section 451 of the Code with respect to conforming the timing of income accruals to financial statements. This summary also does not address tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws, such as:

| • |  | banks, insurance companies or other financial institutions;

| • |  | tax-exempt or governmental organizations;

| • |  | “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

| • |  | real estate investment trusts or regulated investment companies;

| • |  | “qualified foreign pension funds” (within the meaning of Section 897(l)(2) of the Code) and entities all of the interests of which are held by qualified foreign pension funds;

| • |  | brokers or dealers in securities or currencies;

| • |  | traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

| • |  | tax-qualified retirement plans;

| • |  | “qualified shareholders” (within the meaning of Section 897(k)(3) of the Code) or investors therein;

| • |  | persons subject to the alternative minimum tax;

| • |  | partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;

| • |  | persons that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below);

| • |  | persons deemed to sell our Class A common stock under the constructive sale provisions of the Code;

| • |  | persons that acquired our Class A common stock through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

| • |  | certain former citizens or long-term residents of the United States; and

| • |  | persons that hold our Class A common stock as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction or other integrated investment or risk reduction transaction.

PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Non-U.S. Holder Defined

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of our Class A common stock that is not for U.S. federal income tax purposes a partnership or any of the following:

| • |  | an individual who is a citizen or resident of the United States;

| • |  | a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

| • |  | an estate the income of which is subject to U.S. federal income tax regardless of its source; or

| • |  | a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (ii) which has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person for U.S. federal income tax purposes.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our Class A common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, we urge partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) considering the purchase of our Class A common stock to consult their tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership and disposition of our Class A common stock by such partnership.

Distributions

As discussed under “Dividend Policy” above, we do not currently expect to make any cash distributions on our Class A common stock. Distributions of cash or property on our Class A common stock, if any, will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, the distributions will be treated as a non-taxable return of capital to the extent of the non-U.S. holder’s tax basis in our Class A common stock and thereafter as capital gain from the sale or exchange of such Class A common stock. See “—Gain on Disposition of Class A Common Stock” below.

Subject to the withholding requirements under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act (“FATCA”)) and with respect to effectively connected dividends, each of which is discussed below, dividends paid to a non-U.S. holder on our Class A common stock generally will be subject to U.S. withholding tax at a rate of 30% of the gross amount of the dividend unless an applicable income tax treaty provides for a lower rate. To receive the benefit of a reduced treaty rate, a non-U.S. holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) certifying qualification for the reduced rate.

Dividends paid to a non-U.S. holder that are effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, are treated as

165

##### Table of Contents

attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons (as defined under the Code). Such effectively connected dividends will not be subject to U.S. withholding tax if the non-U.S. holder satisfies certain certification requirements by providing the applicable withholding agent with a properly executed IRS Form W-8ECI certifying eligibility for exemption. If the non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends.

Gain on Disposition of Class A Common Stock

Subject to the discussions below under “—Backup Withholding and Information Reporting” and “—Additional Withholding Requirements under FATCA,” a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale or other disposition of our Class A common stock unless:

| • |  | the non-U.S. holder is an individual who is present in the United States for a period or periods aggregating 183 days or more during the calendar year in which the sale or disposition occurs and certain other conditions are met;

| • |  | the gain is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by the non-U.S. holder in the United States); or

| • |  | our Class A common stock constitutes a United States real property interest by reason of our status as a United States real property holding corporation (“USRPHC”) for U.S. federal income tax purposes.

A non-U.S. holder described in the first bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate as specified by an applicable income tax treaty) on the amount of such gain, which generally may be offset by certain U.S. source capital losses recognized in the same taxable year (even though such non-U.S. holder is not considered a resident of the United States), provided that such non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

A non-U.S. holder whose gain is described in the second bullet point above or, subject to the exceptions described in the next paragraph, the third bullet point above, generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons unless an applicable income tax treaty provides otherwise. If such non-U.S. holder is a corporation for U.S. federal income tax purposes whose gain is described in the second bullet point above, then such gain would also be included in its effectively connected earnings and profits (as adjusted for certain items), which may be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty).

We believe that we currently are not a USRPHC for U.S. federal income tax purposes, and we do not expect to become a USRPHC for the foreseeable future. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our U.S. real property interests relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. In the event that we become a USRPHC, as long as our Class A common stock is and continues to be “regularly traded on an established securities market” (within the meaning of the applicable U.S. Treasury Regulations), only a non-U.S. holder that actually or constructively owns, or owned at any time during the shorter of the five-year period ending on the date of the disposition or the non-U.S. holder’s holding period for the Class A common stock, more than 5% of our Class A common stock will be treated as disposing of a U.S. real property interest and will be taxable on gain realized on the disposition of our Class A common stock as a result of our status as a USRPHC. If we were to become a USRPHC and our Class A common stock were not considered to be regularly traded on an established securities market, such holder (regardless of the percentage of stock owned) would be treated as disposing of a U.S. real property interest and

166

##### Table of Contents

would be subject to U.S. federal income tax on a taxable disposition of our Class A common stock (as described in the preceding paragraph), and a 15% withholding tax would apply to the gross proceeds from such disposition.

Non-U.S. holders are urged to consult their tax advisors with respect to the application of the foregoing rules to their ownership and disposition of our Class A common stock.

Backup Withholding and Information Reporting

Payments of dividends to a non-U.S. holder generally will not be subject to backup withholding if the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, W-8BEN-E or W-8ECI (or other applicable or successor form). However, information returns are required to be filed with the IRS in connection with any distributions on our Class A common stock paid to you and the amount of any tax withheld with respect thereto, regardless of whether such distributions constitute dividends or whether any tax was actually withheld.

Payments of the proceeds from a sale or other disposition by a non-U.S. holder of our Class A common stock effected within the United States or through a U.S. office of a broker generally will be subject to information reporting and backup withholding (at the applicable rate) unless the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, W-8BEN-E or W-8ECI (or other applicable or successor form) and certain other conditions are met. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of our Class A common stock effected outside the United States by a non-U.S. office of a broker. However, unless such broker has documentary evidence in its records that the non-U.S. holder is not a United States person and certain other conditions are met, or the non-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of our Class A common stock effected outside the United States by such a broker if it has certain relationships within the United States.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under FATCA and other administrative guidance issued thereunder, on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the discussion of certain proposed Treasury Regulations below) gross proceeds from the sale or other disposition of, our Class A common stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) if the foreign entity is not a “foreign financial entity,” the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each direct and indirect substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise establishes that it qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to noncompliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

167

##### Table of Contents

Under the Code, applicable Treasury Regulations, and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A common stock. On December 13, 2018, the U.S. Department of the Treasury released proposed regulations (which may be relied upon by taxpayers until final regulations are issued), which eliminate FATCA withholding on the gross proceeds from a sale or other disposition of our Class A common stock. We will not pay additional amounts or “gross up” payments to non-U.S. holders as a result of any withholding or deduction for taxes imposed under FATCA. Under certain circumstances, certain non-U.S. holders might be eligible for refunds or credits of such taxes. Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Class A common stock.

INVESTORS CONSIDERING THE PURCHASE OF OUR CLASS COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS (INCLUDING ANY RECENT CHANGES THERETO) TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF U.S. FEDERAL ESTATE AND GIFT TAX LAWS AND ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND TAX TREATIES.

UNDERWRITING

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus, the underwriters named below, for whom Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the number of shares indicated below:

Name |  | Number of Shares |
Morgan Stanley & Co. LLC |  |  |  |
Goldman Sachs & Co. LLC |  |  |  |
BofA Securities, Inc. |  |  |  |
TPG Capital BD, LLC |  |  |  |
Total: |  |  |  |

The underwriters and the representatives are collectively referred to as the “underwriters” and the “representatives,” respectively. The underwriters are offering the shares of Class A common stock subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of Class A common stock offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of Class A common stock offered by this prospectus if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ over-allotment option described below. The offering of the shares of Class A common stock by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters initially propose to offer part of the shares of Class A common stock directly to the public at the offering price listed on the cover page of this prospectus and part to certain dealers at a price that represents a concession not in excess of $    per share under the public offering price. After the initial offering of the shares of Class A common stock, the offering price and other selling terms may from time to time be varied by the representative. Sales of Class A common stock made outside of the United States may be made by affiliates of the underwriters.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to      additional shares of Class A common stock at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. The underwriters may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with the offering of the shares of Class A common stock offered by this prospectus. To the extent the over-allotment option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of Class A common stock as the number listed next to the underwriter’s name in the preceding table bears to the total number of shares of Class A common stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions, and proceeds, before expenses, to us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option.

##### Table of Contents

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately $    million. We have agreed to reimburse the underwriters for their expenses relating to clearance of this offering with the Financial Industry Regulatory Authority (“FINRA”) up to $    .

The underwriters have informed us that they do not intend sales to discretionary accounts to exceed 5% of the total number of shares of Class A common stock offered by them.

We intend to apply to list our Class A common stock on the NYSE under the trading symbol “BETA.”

We and each of our directors and executive officers, have agreed, or will agree, pursuant to a lock-up agreement (the “Lock-up Agreement”), that, without the prior written consent of Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC on behalf of the underwriters, we and they will not, during the period ending 180 days after the date of this prospectus (the “Restricted Period”):

| • |  | offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Class A common stock or any securities convertible into or exercisable or exchangeable for shares of Class A common stock;

| • |  | file any registration statement with the SEC relating to the offering of any shares of Class A common stock or any securities convertible into or exercisable or exchangeable for Class A common stock; or

| • |  | enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our Class A common stock,

whether any such transaction described above is to be settled by delivery of Class A common stock or such other securities, in cash or otherwise. In addition, we and each such person have agreed or will agree that, without the prior written consent of Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC on behalf of the underwriters, we or such other person will not, during the Restricted Period, make any demand for, or exercise any right with respect to, the registration of any shares of Class A common stock or any security convertible into or exercisable or exchangeable for Class A common stock.

The restrictions described in the immediately preceding paragraph do not apply to:

1. | transactions relating to shares of Class A common stock or other securities acquired in open market transactions after the completion of this offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Class A common stock or other securities acquired in such open market transactions during the Restricted Period;

2. | transfers of shares of Class A common stock or any security convertible into or exercisable or exchangeable for Class A common stock (i) as a bona fide gift or for bona fide estate planning purposes, (ii) upon death or by will, testamentary document, or intestate succession, (iii) to an immediate family member of the undersigned or to a trust for the direct or indirect benefit of the undersigned or one or more immediate family members of the undersigned, or (iv) if the undersigned is a trust, to any trustee or beneficiary of the undersigned or the estate of any such trustee or beneficiary;

4. | transfers of shares of Class A common stock or any security convertible into or exercisable or exchangeable for Class A common stock pursuant to a domestic relations order or divorce decree, provided that any filing under Section 16(a) of the Exchange Act or any other public filing or disclosure of such transfer by or on behalf of the undersigned that is required to be made during the Restricted Period as a result of such transfer shall include a statement that such transfer has occurred by operation of law;

Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC, in their sole discretion, may release our Class A common stock and other securities subject to the Lock-Up Agreements described above in whole or in part at any time.

In order to facilitate the offering of our Class A common stock, the underwriters may engage in transactions that stabilize, maintain, or otherwise affect the price of our Class A common stock. Specifically, the underwriters

171

##### Table of Contents

may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the over-allotment option described above. The underwriters can close out a covered short sale by exercising the over-allotment option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the over-allotment option. The underwriters may also sell shares in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our Class A common stock in the open market after pricing that could adversely affect investors who purchase shares of Class A common stock in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of Class A common stock in the open market to stabilize the price of our Class A common stock. These activities may raise or maintain the market price of our Class A common stock above independent market levels or prevent or retard a decline in the market price of our Class A common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representative may agree to allocate a number of shares of Class A common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representative to underwriters that may make Internet distributions on the same basis as other allocations.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing, and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

In the ordinary course of business, we sold, and may in the future sell, solutions to one or more of the underwriters or their respective affiliates in arms-length transactions on market competitive terms.

In August 2025, certain entities acquired shares of our Series C Preferred Stock.    of such shares, which will convert into    shares of our common stock upon completion of this offering, are indirectly attributable to affiliates of TPG Capital BD, LLC, an underwriter in this offering. Accordingly, FINRA deems such shares to be underwriting compensation with an aggregate compensation value of approximately $   . Such shares may not be sold during the offering or sold, transferred, assigned, pledged or hypothecated or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic disposition of such shares for a period of 180 days following the date of effectiveness of the offering.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Beta Technologies, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Beta Technologies, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations and comprehensive loss, convertible preferred stock and stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purposes of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits include performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts)

1. Nature of Business and Liquidity

Beta Technologies, Inc. (“Beta” or the “Company”) was incorporated in Delaware on June 21, 2018, and is headquartered in South Burlington, Vermont. The Company has wholly owned subsidiaries located in the United States to hold its interests in aircraft, intellectual and real property, as well as a wholly owned subsidiary in Canada.

The Company specializes in the design, development, and manufacturing of electric aircraft, including advanced flight control and electric propulsion systems, with a focus on clean aviation technology. The Company is in the process of testing its electric aircraft for commercial feasibility and Federal Aviation Administration (“FAA”) certification. Although the Company is still in the development phase for its aircraft, companies within the medical, military, personal transport, and logistics industries have shown interest in the application to their businesses. In addition, the Company manufactures and operates charge stations and infrastructure for charging electric aircraft. The charging systems provide the power needed to safely, quickly and efficiently charge electric aircraft. The Company also maintains and provides access to simulators for its customers and partners to understand the capabilities of the aircraft.

Since inception, the Company has devoted substantially all of its time and efforts to performing research and development activities, raising capital, recruiting management and technical staff to support these operations and designing manufacturing processes. During 2024, the Company has made investments across facilities, equipment, and tooling needed to move toward manufacturing of its aircraft and charging systems. The Company is subject to risks and uncertainties common to early-stage companies in the aerospace industry including, but not limited to, technical risks associated with the successful research, development, and certification from the FAA, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure. Even if the Company’s aviation development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from sales.

The Company is seeking to complete an initial public offering (“IPO”) of its common stock. Upon the completion of a qualified public offering on specified terms (Note 8), the Company’s outstanding convertible preferred stock will automatically convert into shares of common stock. In the event the Company does not complete an IPO, until such time as the Company can generate significant revenue, if ever, the Company expects to fund its operations through equity offerings or debt financings, credit or loan facilities, potentially other capital resources, or a combination of one or more of these funding sources. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. The Company’s failure to raise capital as and when needed could have a negative impact on its financial condition and its ability to pursue its business strategies. If adequate funds are not available to the Company, the Company may be required to delay, reduce or eliminate certain aircraft development programs or other strategic initiatives. There can be no assurances the Company will be able to obtain additional funding. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

The accompanying consolidated financial statements are prepared in accordance with generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred net losses and negative operating cash flows from operations since inception, and it expects to continue to incur losses and negative

F-7

##### Table of Contents

operating cash flows for the foreseeable future until successful sustainable commercial operations is achieved. Until the Company generates sufficient operating cash flow to fully cover our operating expenses, working capital needs and planned capital expenditures, or if circumstances evolve differently than anticipated, the Company expects to utilize a combination of equity and debt financing to fund any future remaining capital needs.

The Company’s principal uses of cash in recent periods were to fund our research and development activities, personnel cost and support services, including our battery, motor and charging services. Near-term cash requirements will also include spending on manufacturing facilities and equipment, supporting FAA certification, scaled manufacturing operations for commercialization and development and production of aircraft and charging systems. The Company does not have material cash requirements related to current contractual obligations. The Company’s cash requirements are highly dependent upon management’s decisions about the pace and focus of both our short and long-term spending. These conditions and events raise substantial doubt about the Company’s ability to continue as a going concern.

In order to fund its near-term cash requirements, a board member, through an associated company has agreed to fund equity commitments of up to $70,000 of additional Series C preferred stock at the option of the Company. When these funds are combined with the existing cash and cash equivalents of $174,531 on hand as of June 30, 2025, the Company has concluded that management’s plans are probable of being achieved to alleviate substantial doubt about the Company’s ability to continue as a going concern beyond twelve months from the date that the consolidated financial statements are issued.

2. Basis of Presentation and Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements included have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The Company’s consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosure of contingent assets and liabilities at the date of the consolidated financial statements. On an ongoing basis, the Company evaluates the estimates used to prepare its consolidated financial statements. Significant estimates and assumptions reflected within these consolidated financial statements include, but are not limited to, revenue recognition, the valuation of the Company’s common stock and stock based awards, income taxes, long-lived assets, and leases. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.

Cash, Cash Equivalents and Restricted Cash

The Company’s cash and cash equivalents consists of cash maintained within standard checking, savings, demand deposit, and money market accounts. The Company considers all highly liquid investments with a maturity date of three months or less at the date of purchase to be cash equivalents. Restricted cash represents

##### Table of Contents

cash held as collateral with financial institutions in support of a credit arrangement and to provide funds for certain construction activities. Restricted cash is included in prepaid expenses and other current assets for assets that are reasonably expected to be realized in cash or consumed within one year and is included in prepaid expenses and other non-current assets for assets that are reasonably expected to be realized in cash or consumed more than 1 year from the balance sheet date.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the consolidated balance sheet to the total of the amounts in the consolidated statements of cash flows (in thousands):

|  | As of December 31, |
|  | 2024 |  |  | 2023 |
Cash and cash equivalents |  | $ | 301,396 |  |  | $ | 253,545 |
Restricted cash included in: |  |  |  |  |  |  |  |
Prepaid expenses and other current assets |  |  | 149 |  |  |  | 143 |
Prepaid expenses and other non-current assets for assets |  |  | 480 |  |  |  | 448 |
Total cash, cash equivalents, and restricted cash in the consolidated statements of cash flows |  | $ | 302,025 |  |  | $ | 254,136 |

Accounts Receivable

Accounts receivable represent contractual amounts due to the Company for products and services provided to customers. The Company provides for uncollectible amounts by estimating the expected credit losses over the life of the receivable. As of December 31, 2024 and December 31, 2023, the Company estimated the allowance for expected credit losses to be immaterial. If any accounts or portion thereof are deemed uncollectible, such amounts are expensed when that determination is made.

Concentration of Credit Risk

Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash and money-market cash equivalents. The Company’s cash is held in accounts with multiple financial institutions that management believes are creditworthy. Certain account balances may periodically exceed the Federal Deposit Insurance Corporation insurance limits of $250 thousand per account. As a result, there is a concentration of credit risk related to amounts in excess of the insurance limits. The Company regularly monitors the financial stability of these financial institutions and believes that there is no exposure to any significant credit risk in cash and cash equivalents.

Specific customer receivable balances in excess of 10% of total accounts receivable as of December 31, 2024 and 2023 were as follows:

|  | As of December 31, |
|  | 2024 |  |  | 2023 |
Customer A |  |  | 25 | % |  |  | 45 | %
Customer B |  |  | 56 | % |  |  | 53 | %

Property and equipment are stated at cost less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful life of each asset. The estimated useful lives are as follows:

|  | Estimated Useful Life
Computer equipment, furniture and fixtures and software |  | 3-7 years
Machinery and equipment and tooling |  | 10 years
Vehicles and aviation |  | 5 and 20 years
Leasehold and land improvements |  | Lesser of 15 years or remaining lease period
Buildings and structures |  | 40 years
Land |  | Indefinite

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. Expenditures for repairs and maintenance are charged to expense as incurred. Costs for capital assets not yet placed into service are capitalized as construction-in-progress and depreciated once placed into service.

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable based upon estimated future cash flows. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance, and may differ from actual cash flows. If the sum of the projected undiscounted cash flows (excluding interest) is less than the carrying value of the assets, the assets will be written down to the estimated fair value in the period in which the determination is made.

Deferred Offering Costs

The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds from the offering, either as a reduction of the carrying value of the convertible preferred stock or in stockholders’ equity as a reduction of additional paid-in-capital generated as a result of the offering. Should the planned equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations and comprehensive loss. The Company did not have any deferred offering costs as of December 31, 2024 and 2023.

Fair Value Measurements

Fair value is defined as the price that the Company would receive to sell an asset or pay to transfer a liability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market,

F-10

##### Table of Contents

the most advantageous market for the investment or liability. ASC 820, Fair Value Measurements (“ASC 820”), establishes a hierarchy of inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available.

Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy applies only to the valuation inputs used in determining the reported fair value of investments and is not a measure of the investment credit quality. The hierarchy defines three levels of valuation inputs:

Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2—Quoted prices in markets that are not considered to be active or financial instrument valuations for which all significant inputs are observable, either directly or indirectly; and,

Level 3—Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

Financial instruments are categorized in their entirety based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment and considers factors specific to the investment.

The Company monitors the availability of inputs that are significant to the measurement of fair value to assess the appropriate categorization of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the Company’s policy is to recognize significant transfers between levels at the end of the reporting period. The significance of transfers between levels is evaluated based upon the nature of the financial instrument and size of the transfer relative to total net assets available for benefits. The Company’s cash equivalents of $190,223 and $49,891 as of December 31, 2024 and 2023, respectively, are determined to be Level 1 in the fair value hierarchy described above.

For the years ended December 31, 2024 and December 31, 2023, there were no transfers between Level 1, Level 2 and Level 3.

Leases

Under ASC 842, Leases (“ASC 842”), the Company determines if an arrangement is or contains a lease at inception. For leases with a term of 12 months or less, the Company does not recognize a right-of-use asset or lease liability. Lease expense for operating leases is recognized on a straight-line basis over the lease term and is included as a component of research and development and general and administrative expenses in the consolidated statements of operations and comprehensive loss based on the nature of the lease.

As the Company’s leases typically do not provide an implicit rate, it uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. Operating lease right-of-use assets also include the effect of any lease payments made and lease incentives received. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company has elected, as a practical expedient, an accounting policy by class of underlying asset to not separate lease and non-lease components, and instead, accounted for them as a single lease component. As the Company enters into new leases, it will continue to evaluate this accounting policy for any new classes of underlying assets.

F-11

##### Table of Contents

Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments less applicable lease incentives over the lease term. Variable components of the lease payments such as fair market value adjustments, taxes, utilities, and maintenance costs are expensed as incurred and not included in determining the present value.

The Company classifies contractual lease arrangements where it is the lessor as a sales-type, direct financing or operating lease. The associate lease income is classified within Service Revenue on the consolidated statements of operations and comprehensive loss. For sales-type leases, the Company derecognizes the leased asset and recognizes the net investment in the lease on the balance sheet. The Company also sub-leases a portion of its R&D testing facilities and any associated rental income is recognized on a straight-line basis over the respective operating lease terms. Sub-lease income is presented as an offset to the related lease expense within the consolidated statements of operations and comprehensive loss.

Asset Retirement Obligations

The Company establishes an asset retirement obligation (“ARO”) based on the present value of contractually required estimated future costs to retire long-lived assets at the termination or expiration of a lease. The asset associated with the ARO is amortized over the corresponding lease term to operating expense and the ARO is accreted to the value of the obligation at the end of the lease term. As of December 31, 2024 and 2023, the Company had ARO liabilities of $444 and $214, respectively, recorded within other liabilities.

Preferred Stock

The Company’s Series A, Series B and Series C convertible preferred stock (together, the “Preferred Stock”) are classified in stockholders’ equity on the Company’s consolidated balance sheet. The Preferred Stock is redeemable for cash upon the occurrence of a Deemed Liquidation Event, which is defined to include a merger or consolidation of the Company with another entity for which the Company is a constituent party (or a subsidiary of the Company is a constituent party) and sale of all or substantially all of the assets of the Company. As the initiation and consummation of a Deemed Liquidation Event requires approval by the Board and such approval is solely within the control of the Company as the holders of Super Voting Stock, a Deemed Liquidation Event cannot be consummated outside of the control of the Company.

Additionally, the Preferred Stock is subject to paid in kind (PIK) dividends that may be settled in cash, upon the occurrence of a liquidation, dissolution, winding up of the Company, or a Deemed Liquidation Event, or in shares of the Company’s Common Stock in all other settlement scenarios. The PIK dividends only accrue over a two-year period starting on the Preferred Stock’s issuance date. Since the PIK dividends can only be settled in cash upon events that are within the Company’s control and have an implicit cap (i.e. due to the limited accrual period) on the number of shares issuable in share settlement scenarios, they do not cause the Preferred Stock to be classified outside stockholders’ equity on the Company’s consolidated balance sheet.

Revenue Recognition

The Company’s revenues from contracts with customers, including domestic commercial customers and the U.S. Government and its agencies, include the sale of products and provision of services related to the development of electric aircraft, operation of or access to corresponding charge stations and ground service equipment (“GSE”), and aircraft components. Revenues are generated from the following contract types: firm fixed price (“FFP”) where the Company is paid a predetermined price; cost-reimbursable (“CP”) where the Company is paid for reimbursable costs plus a fixed or variable fee, or time and materials (“T&M”) where the Company is paid a fixed hourly rate plus reimbursed for other associated costs. During the years ended December 31, 2024 and 2023, the Company’s revenues were predominantly derived from firm fixed price

F-12

##### Table of Contents

contracts. The terms in the Company’s contracts generally require payment within 30 to 60 days of invoice issuance, which is typically based on a milestone basis or upon completion or delivery of goods or services, depending on the contract. The Company’s contracts do not contain significant financing components, as differences that arise between receipt of payment and delivery of goods or services is generally within a one-year period.

The Company categorized revenue and costs associated with tangible products as product revenue and revenue and costs associated with engineering, consulting or other services arrangements as service revenue. Service revenue also includes revenue and costs associated with usage and priority access from the Company’s charge stations and from operating and sales-type lease income. In cases where a singular performance obligation encompasses both elements of product revenue and service revenue, the Company classifies the associated revenues and costs based upon the predominant nature of the overall promise made to the customer.

The Company recognizes revenue when a customer obtains control of promised goods or services in accordance with ASC 606 Revenue from Contracts with Customers. The amount of revenue reflects the consideration that the Company expects to be entitled to receive in exchange for these goods or services. The Company applies the following five steps: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to performance obligations in the contract, and (5) recognize revenue when (or as) the Company satisfies a performance obligation.

Certain of the Company’s contracts permit its customers to unilaterally terminate or cancel the contract without substantive termination penalties incurred by the customer upon providing the Company notice of approximately 30-60 days in advance. In such cases, the Company limits the contract duration to the notice period.

A performance obligation is the unit of account in ASC 606 and represents a promise in a contract to transfer a distinct good or service, or a series of distinct goods or services. At contract inception, the Company assesses whether the goods or services promised within each contract are separate performance obligations. Goods and services that are determined not to be distinct are combined with other promised goods and services until a distinct bundle is identified. The Company’s product and service revenue includes single or multiple performance obligations as the underlying contracts specify discrete activities or deliverables in which the customer can benefit from use of each either on its own or with other readily available resources.

Contract modifications frequently occur in the performance of the Company’s contracts. In most instances, the nature of the modification determines whether or not the Company accounts for the modification as an adjustment to the existing contract, in the case of the original goods or services being modified, or as a new contract when the modification provides for additional goods and services that are distinct.

The transaction price is the amount of consideration that the Company would expect to be entitled to under a contract upon fulfillment of the performance obligations. The starting point for estimating the transaction price is the selling price stipulated in the order, however, the Company also includes an estimate of variable consideration to the extent it is probable that it will not result in a significant future reversal of revenue. Taxes collected from customers and remitted to government authorities are recorded on a net basis.

The Company recognizes revenue over time for a performance obligation when there is a continuous transfer of control to the customer, the Company’s performance on the contract creates or enhances an asset that the customer controls as the asset is created or enhanced, or the Company’s performance does not create an asset with an alternative use to the Company and there is an enforceable right to payment for performance completed to date. All other performance obligations are recognized at a point in time. The Company’s product revenues are either recognized over time, using the cost-to-cost input method, or at a point of time which is typically dependent upon whether or not an asset is created with an alternative use. In determining whether an asset is

F-13

##### Table of Contents

created with an alternative use, the Company considers on a contract-by-contract basis the level of configuration required to meet customer demands and the overall customization of the product. The Company’s service revenue is typically recognized over time when there is a continuous transfer of control to the customer, using a cost-to-cost or time expended input method.

Contract Estimates

For performance obligations recognized over time using an input method, the Company estimates the total cost or time to be incurred, such as flight hours, to complete the performance obligation and recognizes revenue based on a percentage of the associated input in relation to the estimated total at period end. As a significant change in one or more of these estimates could affect the profitability of the Company’s contracts, the Company regularly reviews and updates its contract-related estimates. When changes in estimated total costs or time at completion or in estimated total transaction price are determined, the related impact is recognized on a cumulative basis through revenues. The Company’s contracts did not contain material contract estimates for the years ended December 31, 2024 and 2023.

Contract Balances

Contract assets primarily represent services performed by the Company for which revenue recognition precedes the billing of the services. Contract assets are classified as current assets on the consolidated balance sheets as of December 31, 2024, and 2023. Contract liabilities primarily relate to contracts where the Company received payments but has not yet satisfied the related performance obligations. At each reporting period, to the extent that customer contract billings exceed revenue recognized on such contracts, these contract liabilities are presented as deferred revenue, current or deferred revenue, noncurrent on the consolidated balance sheets as of December 31, 2024, and 2023.

Costs of Revenue

Cost of contracts includes the direct cost of materials, labor, subcontractors, depreciation, and overhead costs (where allowable) used in the production of charge pads, aircraft components, and services provided to customers. Cost of revenues associated with product sales is comprised of purchases made directly for contractual performance obligations primarily recognized overtime, where no inventories are held. Costs are expensed as incurred except for costs incurred to fulfill a contract. which are capitalized and amortized on a straight-line basis over the expected period of performance.

Remaining Performance Obligations

Remaining performance obligations represent the amount of contracted future revenue that has not yet been recognized. As of December 31, 2024, the Company’s remaining performance obligations were $17,997. The Company currently expects to recognize approximately $13,062 of the remaining performance obligations as revenue during the year ended December 31, 2025 and the remaining to be recognized thereafter.

Governmental Assistance

Governmental assistance is provided to the Company in different forms with varying structures and terms. Governmental assistance includes tax credits, cash grants, and project grants. Often, government assistance is provided to the Company for a particular purpose or to take specific actions. Because there is no specific guidance under U.S. GAAP that addresses the recognition and measurement of government assistance received by non-government entities, the Company accounts for government assistance by analogy to IAS 20, Accounting for Government Grants.

Under the Company’s accounting policy for government assistance, payments are recognized on a systematic basis over the period in which the grant is intended to compensate. For grants or components thereof

F-14

##### Table of Contents

related to capital expenditures, the Company records payments received as a reduction to the carrying amount of the associated asset which reduces depreciation expense. For grants or components thereof related to income, the Company records a reduction in the related expense that the grant is intended to defray, such as research and development or general and administrative, as applicable in the period in which the corresponding cost is recognized.

Research and Development Costs

Research and development expenses include employee payroll, consulting, materials, tooling, rent and other corporate costs attributable to research and development activities and are expensed as incurred. Certain materials purchased by the Company are determined to have an alternative use to the Company through future research projects or manufacturing. The costs of materials with alternative use to the Company are included within other current assets and expensed within the relevant financial caption as the items are consumed.

Stock Based Compensation

The Company measures all stock options and other stock based awards granted to employees, non-employees, and directors based on the fair value on the date of the grant and recognizes compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. Generally, the Company issues stock options with only service-based vesting conditions and records the expense for these awards using the straight-line method. The Company recognizes forfeitures at the time forfeitures occur.

The Company measures stock based awards granted to consultants and non-employees based on the fair value of the award on the grant date. Compensation expense is recognized over the period during which services are rendered by such consultants and non-employees.

The Company classifies stock based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company is a private company and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until it has adequate historical data regarding the volatility of its own traded stock price. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The expected term of stock options is equal to the weighted average vesting term plus the contractual term divided by two. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is zero because the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent

F-15

##### Table of Contents

it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The Company accounts for uncertainty in income taxes recognized in the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.

Debt Issuance Costs

Costs incurred in connection with the issuance of the Company’s long-term debt have been recorded as a direct reduction against the debt and amortized over the life of the associated debt as a component of interest expense using the effective interest method.

Foreign Currency

The Company’s reporting currency is the US dollar. The functional currency of the Company’s foreign subsidiary is the local currency (Canadian dollar), as it is the monetary unit of account of the principal economic environment in which the Company’s foreign subsidiary operates. All assets and liabilities of the foreign subsidiary are translated at the current exchange rate as of the end of the period, and expenses are translated at average exchange rates in effect during the period. The gain or loss resulting from the process of translating foreign currency consolidated financial statements into US dollars is reflected as a foreign currency cumulative translation adjustment and reported as a component of accumulated other comprehensive loss.

Comprehensive Loss

Comprehensive loss consists of two components, net loss and other comprehensive income (loss), net of tax. Other comprehensive income (loss), net of tax, refers to revenue, expenses, gains, and losses that under generally accepted accounting principles are recorded as an element of stockholders’ equity but are excluded from net loss. The Company’s other comprehensive income (loss), net of tax, consists of foreign currency translation adjustments that result from consolidation of its foreign entities.

Derivative Financial Instruments

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s consolidated financial statements. The Company evaluates its contracts and financial instruments to determine if those contracts, or embedded components of those contracts, qualify as derivative financial instruments to be separately accounted for in accordance with ASC 815, Derivatives and Hedging (“ASC 815”). The accounting treatment of derivative financial instruments requires that the Company record embedded features and any related freestanding instruments at their fair values as of the inception date of the agreement and at fair value as of each subsequent balance sheet date. Any change in fair value is recorded as non-operating, non-cash income or expense for each reporting period at each balance sheet date. The Company’s notes payable contains a significant discount to be bifurcated from the host instrument, along with other bifurcated features related to events of default. Due to the low risk of default upon funding and through December 31, 2024, no value has been assigned to these features. Any changes in the value of these features in future periods would be recorded through the consolidated statements of operations and comprehensive loss. The Company reassesses the classification of its derivative instruments at each balance sheet date. If the classification changes as a result of events during the period, the contract is reclassified as of the date of the event that caused the reclassification.

Net Loss per Share

Prior to the amendment of the Company’s certificate of incorporation on October 23, 2024, the Company calculated basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. Subsequent to the amendment, the Company calculates diluted net loss per share attributable to common stockholders in conformity with the if-converted method, as the Company’s convertible preferred stock is no longer a participating security. Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share attributable to common stockholders is computed by giving effect to all potentially dilutive securities outstanding for the period.

The Company has two classes of common stock that are identical except with respect to voting (Refer to Note 8 for additional detail). As a result, basic and diluted net income per share of Common Stock and Super Voting Common Stock are equivalent.

The Company has generated a net loss for each of the periods presented. Accordingly, basic and diluted net loss per share attributable to common stockholders are the same because the inclusion of the potentially dilutive securities would be anti-dilutive. The net loss per share is the same under both the two-class method and the if-converted method as the holders of the convertible preferred stock are not contractually obligated to participate in losses.

Recently Adopted Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires public entities to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The guidance also requires all public entities with a single reportable segment have to provide all the disclosures required by ASC 280, including the significant segment expense disclosures. The new standard is effective for fiscal years beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. The Company adopted the ASU 2023-07 in 2024 (see note 12).

Contract assets decreased primarily due to billings related to the satisfaction or partial satisfaction of performance obligations during 2024 exceeding the revenue recognized. Contract liabilities increased during 2024, primarily due to payments received in excess of revenue recognized on these performance obligations. During 2024 and 2023 we recognized $895 and $955 of our contract liabilities as of December 31, 2023 and 2022, respectively, as revenue.

5. Notes Payable

On December 13, 2023, Beta entered into a credit agreement with the Export-Import Bank of the United States (“Ex-Im”).

6. Leases

The Company’s lease arrangements consist of facility, vehicle, aircraft, and equipment leases, as well as other short-term leases for storage and office space. The Company determines if an arrangement is a lease and identifies the classification of the lease as a financing lease or an operating lease at inception.

F-20

##### Table of Contents

At the date of commencement, lease liabilities are recorded at the present value of the future minimum lease payments over the lease term. The lease term is equal to the initial term at commencement plus any renewal or extension options that the Company is reasonably certain will be exercised. ROU assets at the date of commencement are equal to the amount of the initial lease liability, the initial direct costs incurred by the Company, and any prepaid lease payments less any incentives received.

The Company’s lease terms generally allow for the extension or termination of its leases and the Company accounts for the extension and termination when it is reasonably certain that it will exercise the option or terminate the lease. Reassessment of the lease term occurs when there is a significant event or a significant change in circumstances that is within the control of the Company that directly affects whether the Company is reasonably certain to exercise or not exercise an option to extend or terminate the lease or to purchase the underlying asset.

The table below presents certain information related to the lease costs (in thousands):

Certain lease agreements contain provisions which could require restoration of real estate to its original condition at the end of the lease term. The Company has recorded asset retirement obligations for which the liability was initially measured at fair value and subsequently adjusted for accretion expense and changes in the amount or timing of the estimated cash flows. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s remaining useful life. For the years ended December 31, 2024 and 2023, the Company had $444 and $214 of asset retirement obligations included within other liabilities.

7. Commitments and contingencies

Commitments

On May 25, 2021, the Company exercised its right to buy shares back from a former employee of the Company, to be paid over five years. In accordance with the fair value of the shares determined by the Company, as of December 31, 2024 and 2023, the Company’s remaining liability for the share buy-back was $913 and $1,827, respectively. As of December 31, 2024 and 2023 there were outstanding checks of $477 and $3,005, respectively, for principal and interest payments made to the former employee that remained uncashed.

Legal Proceedings

At each reporting date, the Company evaluates whether a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses as incurred the costs related to its legal proceedings.

On May 26, 2021, the Company was named a defendant in an action brought by Blue Force Technologies, Inc. (“Blue Force”) in the U.S. District Court for the Middle District of North Carolina. The complaint alleges that the Company breached the parties’ contract by improperly terminating their agreement and allegedly excluding Blue Force from subsequent participation in a Company program. Blue Force also alleges that the Company has improperly obtained and made use of proprietary Blue Force information. The Company filed a motion for summary judgment that it lawfully terminated the agreement, which was granted by the court in 2023. In 2023, Blue Force made a one-time settlement payment to the Company, which has been presented as an offset to the Company’s general and administrative expenses. As part of the settlement, Beta also secured assignment of ownership and/or a worldwide, irrevocable license in perpetuity for all intellectual property developed for it by Blue Force.

Indemnification Agreements

As permitted under Delaware law, the Company indemnifies its officers, directors, and employees for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The term of the indemnification is for the officer’s or director’s lifetime. Further, in the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is, in many cases, unlimited. To date however, the Company has not incurred any material costs as a result of such indemnifications nor experienced any losses related to them. As of December 31, 2024, the Company was not aware of any claims under indemnification arrangements and does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible; therefore, no related reserves were established.

9. Stock Based Compensation

2018 Equity Incentive Plan

On August 1, 2018, the Company adopted the 2018 Equity Incentive Plan, as amended (the “2018 Plan”), which provides for the Company to grant qualified incentive stock options, nonqualified stock options, stock grants, and other stock based awards to employees and non-employees to purchase the Company’s common stock.

As of December 31, 2024 and 2023, the total number of shares of common stock that may be issued under the 2018 Plan was 3,930,962, of which 720,584 and 1,119,599 remained available for future grant.

The exercise price for incentive options is determined at the discretion of the board of directors. All incentive options granted to any person possessing less than 10% of the total combined voting power of all classes of stock may not have an exercise price of less than 100% of the fair market value of the common stock on the grant date.

The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. Under the Act, research and experimental expenditures incurred for tax years beginning after December 31, 2021 must be capitalized and amortized ratably over five or fifteen years for tax purposes, depending on where the research activities are conducted.

The Company evaluated the positive and negative evidence bearing upon its ability to realize the deferred tax assets as of December 31, 2024. Management considered the Company’s cumulative U.S. losses and concluded as of December 31, 2024, that it was more likely than not that the Company would not realize the

##### Table of Contents

benefits of the U.S. deferred tax assets. Accordingly, a full valuation allowance was established against the U.S. net deferred tax assets as of the years ended December 31, 2024 and 2023. The valuation allowance increased by $71,618 for the year ended December 31, 2024, primarily as a result of operating losses generated with no corresponding financial statement benefit.

As of December 31, 2024, the Company had federal and state net operating loss carryforwards of approximately $364,723 and $289,303, respectively, which carryforward indefinitely for federal purposes and begin to expire in 2030 for state purposes. As of December 31, 2024 and 2023, the Company had federal research and development tax credit carryforwards of approximately $19,043 and $11,995, respectively, which begin to expire in 2039. As of December 31, 2024 and 2023, the Company had state research and development tax credit carryforwards of approximately $2,858 and $1,375, respectively, which begin to expire in 2032. As of December 31, 2024 and 2023, the Company had foreign federal research and development tax credit carryforwards of approximately $144 and $197 respectively, which begin to expire in 2043.

The Company’s ability to utilize the tax credit carryforwards in the future may be subject to substantial restrictions in the event of past or future ownership changes as defined in Section 382 of the Internal Revenue Code of 1986, as amended, and similar state tax law. The Company has not completed a full tax credit study through December 31, 2024.

The Company files federal and state tax returns in the United States as well as foreign tax returns in Canada. All tax years since incorporation remain open to examination by the major taxing jurisdictions (federal, state and foreign) to which the Company is subject, as carryforward attributes generated in years past may still be adjusted upon examination by the Internal Revenue Service (IRS) or other authorities if they have or will be used in a future period. The Company is not currently under examination by the IRS or any other jurisdictions for any tax year.

The evaluation of uncertain tax positions is based on factors that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity, and changes in facts or circumstances related to a tax position. The Company evaluates uncertain tax positions on an annual basis and adjusts the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. As of December 31, 2024, the Company had no recorded liabilities for uncertain tax positions and had no accrued interest or penalties related to uncertain tax positions. The Company does not expect a material change in unrecognized tax benefits in the next twelve months.

The Company permanently reinvests the earnings of its foreign subsidiary, and therefore does not provide for taxes that could result from the distributions of those earnings to the U.S.

The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions. These reserves are based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. Potential interest and penalties associated with such uncertain tax positions are recorded as a component of income tax expense. The Company has recorded deferred tax assets of $183 in prepaid expenses and other non-current assets and deferred tax liabilities of $45 in other non-current liabilities as of December 31, 2024, and 2023, respectively.

11. Net Loss Per Share

Net loss per share basic and diluted net loss per share attributable to common stockholders was calculated as follows (in thousands, except share and per share amounts):

|  | Year Ended December 31, |
|  | 2024 |  |  | 2023 |
Numerator: |  |  |  |  |  |  |  |
Net loss |  | $ | (275,645 | ) |  | $ | (175,563 | )

Net loss attributable to common stockholders |  |  | (306,346 | ) |  |  | (201,931 | )
Denominator: |  |  |  |  |  |  |  |
Weighted average common shares outstanding, basic and diluted |  |  | 7,089,302 |  |  |  | 7,036,685 |
Net loss per share, basic and diluted |  | $ | (43.21 | ) |  | $ | (28.70 | )

The Company’s Series B and Series C Preferred Stockholders are entitled to cumulative dividends based on their stated value as described in Note 8. As such, the Company calculates its net loss attributable to common stockholders by adjusting its net loss for the aggregate cumulative dividends that had accrued since the original issuance dates in the period in which the Preferred Stockholders became legally entitled to such dividends.

The Company’s potentially dilutive securities, which include stock options to purchase common stock and Preferred Stock, have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The following potentially dilutive securities have been excluded from the calculation of diluted net loss per share due to their anti-dilutive effect:

|  | Year Ended December 31, |
|  | 2024 |  |  | 2023 |
Convertible Series A preferred stock |  |  | 8,789,710 |  |  |  | 8,789,710 |

12. Segment Reporting

The Company has one operating and reportable segment – Development and Manufacturing Electric Aircrafts. The Company determined its reportable segment using the management approach based on how the chief operating decision maker (“CODM”) evaluates the business. Substantially all Company’s fixed assets are located in the United States and all of the Company’s revenue is generated in the United States. The company’s foreign operations consist of expenses associated with engineering and related supporting administrative services.

The Company’s CODM is its Chief Executive Officer. As the Company has a single reportable segment and is managed on a consolidated basis, the measure of segment profit or loss is consolidated net loss as reported in the consolidated statements of operations and comprehensive loss. The CODM reviews the financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. The CODM does not use any segment asset measures to assess performance and decide how to allocate resources. The Company does not have intra-entity sales or transfers.

ARMI will reimburse Beta for all costs related to the installation of the charging stations and FOB, up to a total amount of $9,950, which includes a portion of reimbursement for general and administrative costs. The FOB construction and delivery is considered a contract with a customer and revenue is recorded under ASC 606 (see Note 3). The charging station grants are recorded as a reduction to the asset carrying value within property and equipment on the balance sheet, and as a reduction to the general and administrative expenses incurred on the consolidated statements of operations and comprehensive loss. The grant receivable is recorded as the project costs are incurred on the charging stations. The Company recorded $2,828 and $3,224 as a reduction to construction in progress and $1,119 and $1,441 as a reduction to general and administrative expenses during the years ended December 31, 2024 and 2023, respectively.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts)

(Unaudited)

1. NATURE OF OPERATIONS AND LIQUIDITY

Beta Technologies, Inc. (“Beta” or the “Company”) designs, manufactures, and sells high-performance electric aircraft, advanced electric propulsion systems, charging systems and components. The Company has wholly owned subsidiaries located in the United States to hold its interests in aircraft, intellectual and real property, as well as a wholly owned subsidiary in Canada. The Company specializes in the design, development, and manufacturing of electric aircraft, including advanced flight control and electric propulsion systems, with a focus on clean aviation technology. The Company is in the process of testing its electric aircraft for commercial feasibility and Federal Aviation Administration (“FAA”) certification. Although the Company is still in the development phase for its aircraft, companies within the medical, military, personal transport, and logistics industries have shown interest in the application to their businesses. In addition, the Company manufactures and operates charge stations and infrastructure for charging electric aircraft. The charging systems provide the power needed to safely, quickly and efficiently charge electric aircraft. The Company also maintains and provides access to simulators for its customers and partners to understand the capabilities of the aircraft.

Since inception, the Company has devoted substantially all of its time and efforts to performing research and development activities, raising capital, recruiting management and technical staff to support these operations and designing manufacturing processes. To date, the Company has made investments across facilities, equipment, and tooling needed to move toward manufacturing of its aircraft and charging systems. The Company is subject to risks and uncertainties common to early-stage companies in the aerospace industry including, but not limited to, technical risks associated with the successful research, development, and certification from the FAA, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure. Even if the Company’s aviation development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from sales.

The Company is seeking to complete an initial public offering (“IPO”) of its common stock. Upon the completion of a qualified public offering on specified terms (Note 8), the Company’s outstanding convertible preferred stock will automatically convert into shares of common stock. In the event the Company does not complete an IPO, until such time as the Company can generate significant revenue, if ever, the Company expects to fund its operations through equity offerings or debt financings, credit or loan facilities, potentially other capital resources, or a combination of one or more of these funding sources. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. The Company’s failure to raise capital as and when needed could have a negative impact on its financial condition and its ability to pursue its business strategies. If adequate funds are not available to the Company, the Company may be required to delay, reduce or eliminate certain aircraft development programs or other strategic initiatives. There can be no assurances the Company will be able to obtain additional funding. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient funding on terms acceptable to the Company to fund continuing operations, if at all.

The accompanying condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”) applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred net losses and negative operating cash flows from operations since inception, and it expects to continue to incur losses and negative operating cash flows for the foreseeable future until successful

sustainable commercial operations is achieved. Until the Company generates sufficient operating cash flow to fully cover our operating expenses, working capital needs and planned capital expenditures, or if circumstances evolve differently than anticipated, the Company expects to utilize a combination of equity and debt financing to fund any future remaining capital needs.

The Company’s principal uses of cash in recent periods were to fund research and development activities, personnel cost and support services, including battery, motor and charging services. Near-term cash requirements will also include spending on manufacturing facilities and equipment, supporting FAA certification, scaled manufacturing operations for commercialization and development and production of aircraft and charging systems. The Company does not have material cash requirements related to current contractual obligations. The Company’s cash requirements are highly dependent upon management’s decisions about the pace and focus of both short and long-term spending. These conditions and events raise substantial doubt about the Company’s ability to continue as a going concern.

In order to fund its near-term cash requirements, on July 16, 2025, the Company entered into a sale-leaseback transaction for two of its buildings with an associated company of a board member and received $32,658 in net proceeds from the sale with an initial leaseback term of 29 years. Through August 2025, the Company issued 623,476 shares of previously authorized Series C Preferred Stock and expanded the shares authorized and issued pursuant to the Series C Preferred Stock offering by 620,600 shares that provided aggregate net proceeds of $142,409. The participants of the Series C Preferred Stock offering consisted of new and previous investors, including board members and their associated companies, and certain members of management.

When these funds are combined with the existing cash and cash equivalents of $174,531 on hand as of June 30, 2025, the Company has concluded that management’s plans are probable of being achieved to alleviate substantial doubt about the Company’s ability to continue as a going concern beyond twelve months from the date that the condensed consolidated financial statements are issued.

2. BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The accompanying unaudited interim condensed consolidated financial statements included have been prepared in accordance with US GAAP for interim financial reporting and as required by Regulation S-X, Rule 10-01. These interim condensed consolidated financial statements are unaudited and, in the opinion of management, reflect all normal recurring adjustments necessary to fairly present the financial position, results of operations, cash flows, and change in equity for the periods presented. Results for the periods presented are not necessarily indicative of the results that may be expected for any subsequent period. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes as of and for the year ended December 31, 2024. The December 31, 2024 condensed consolidated balance sheet was derived from the audited consolidated financial statements as of that date. Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The Company’s condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

There have been no changes to the Company’s significant accounting policies described in Note 2 “Summary of Significant Accounting Policies” to the consolidated financial statements and notes as of and for the year ended December 31, 2024 included elsewhere in this registration statement, that have had a material impact on the condensed consolidated financial statements and related notes, other than those described below. Certain items in the prior year’s audited consolidated financial statements have been reclassified to conform to the current presentation.

Customer B |  |  | 18 | % |  |  | 34 | %
Customer E |  |  | 15 | % |  |  | * |

* | Less than 10%

Deferred Offering Costs

The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of the equity financing, these costs are recorded as a reduction of the proceeds from the offering, either as a reduction of the carrying value of the convertible preferred stock or in stockholders’ equity as a reduction of additional paid-in-capital generated as a result of the offering. Should the planned equity financing be abandoned, the deferred offering costs will be expensed immediately as a charge to operating expenses in the consolidated statements of operations and comprehensive loss. The Company recorded $1,877 of deferred offering costs as of June 30, 2025 and there were no deferred offering costs as of December 31, 2024.

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The new standard is effective for annual periods beginning after December 15, 2025, with early adoption permitted. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is still evaluating the effects of adopting this accounting standard on the condensed consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (subtopic 220-40): Disaggregation of Income Statement Expenses, which requires public entities to disclose in the notes to the consolidated financial statements, of specified information about certain costs and expenses. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (subtopic 220-40): Disaggregation of Income Statement Expenses, Clarifying the Effective Date. ASU 2025-01 clarifies that the guidance in ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The Company is still evaluating the effects of adopting this accounting standard on the condensed consolidated financial statements.

3. REVENUE RECOGNITION

Disaggregated Revenue

The Company disaggregates revenue from contracts with customers by customer type, product or service type, and geographic location, as the Company believes these categories best depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

The Company’s revenues for customer type are as follows (in thousands):

|  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |
U.S. Government |  | $ | 5,720 |  |  | $ | 4,903 |

Total |  | $ | 15,565 |  |  | $ | 7,589 |

The Company’s revenues for product or service type are as follows (in thousands):

|  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |

Total |  | $ | (15,590 | ) |  | $ | (12,761 | )

Contract liabilities increased during the six months ended June 30, 2025, primarily due to payments received in excess of revenue recognized on performance obligations.

5. NOTES PAYABLE

On December 13, 2023, Beta entered into a credit agreement with the Export-Import Bank of the United States (“Ex-Im”). The Ex-Im credit agreement provides a $170,103 direct loan facility which the Company drew $170,103 as of June 30, 2025 and December 31, 2024. Of the $170,103 in principal amount of borrowings made under the Ex-Im credit agreement, $151,250 can be used to finance the costs of construction of the Company’s production facility, with the remaining $18,853, or 12.46% of borrowings, used to finance the total exposure fees incurred under the agreement. The discount of $20,207 as of December 31, 2024 consists of the initial exposure fee and debt issuance costs. As of June 30, 2025 and December 31, 2024, exposure fees were $18,853 and debt issuance costs were $1,354, which are amortized to interest expense on an effective interest rate basis over the term of the Ex-Im credit agreement.

Borrowings under the Ex-Im credit agreement bear interest at a fixed rate per annum of 5.52%, payable quarterly in arrears. The effective per annum interest rate on the Company’s outstanding borrowings under the Ex-Im credit agreement, which takes into account timing and amount of borrowings and payments, exposure fees, and debt issuance costs, is 7.32%. Borrowings under the Ex-Im credit agreement are required to be repaid in 54 quarterly installments, commencing on September 20, 2025, with a maturity date of December 20, 2038. The Ex-Im credit agreement is secured by first-priority liens on a certain production facility.

The Company’s long-term notes payable is recorded on an amortized cost basis and has a fair value of $157,641 and $157,043 as of June 30, 2025 and December 31, 2024, respectively. The fair value of the notes payable is based on quoted prices in similar markets, which is a Level 2 input within the fair value hierarchy.

6. LEASES

The Company’s lease arrangements consist of facility, vehicle, aircraft, and equipment leases, as well as other short-term leases for storage and office space. There have been no material changes to the Company’s leases during the six months ended June 30, 2025. For additional information, see Note 6, “Leases” in the audited consolidated annual financial statements for the years ended December 31, 2024 and 2023 included elsewhere in this registration statement.

7. COMMITMENTS AND CONTINGENCIES

Commitments

On May 25, 2021, the Company exercised its right to buy shares back from a former employee of the Company, to be paid over five years. In accordance with the fair value of the shares determined by the Company, as of June 30, 2025 and December 31, 2024, the Company’s remaining liability for the share buy-back was $691 and $913, respectively.

Legal Proceedings

At each reporting date, the Company evaluates whether a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company expenses as incurred the costs related to its legal proceedings. As of June 30, 2025, the Company was not aware of any material existing, pending, or threatened legal actions against the Company.

Indemnification Agreements

As permitted under Delaware law, the Company indemnifies its officers, directors, and employees for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The term of the indemnification is for the officer’s or director’s lifetime. Further, in the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and other parties with respect to certain matters including, but not limited to, losses arising out of breach of such agreements or from intellectual property infringement claims made by third parties. The maximum potential amount of future payments the Company could be required to make under these indemnification

F-43

##### Table of Contents

agreements is, in many cases, unlimited. To date however, the Company has not incurred any material costs as a result of such indemnifications nor experienced any losses related to them. As of June 30, 2025, the Company was not aware of any claims under indemnification arrangements and does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible; therefore, no related reserves were established.

8. CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS’ EQUITY

Common Stock

As of June 30, 2025 and December 31, 2024, the Company had 35,000,000 shares of common stock authorized and 5,859,988 and 5,804,680 shares of common stock issued and outstanding, respectively. Each holder of the Company’s common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors.

Super Voting Common Stock

During 2021, the Company authorized and issued 1,332,277 shares of super voting common stock, which remain outstanding as of June 30, 2025. The holder of the Company’s super voting common stock is entitled to forty votes for each share on all matters submitted to a vote of the stockholders, including the election of directors. Each share of super voting common stock is convertible into one share of common stock at any time.

The size of the board of directors cannot be changed without the consent of the individual owning the shares of super voting common stock. The individual also retains the right to designate a majority of the board. Two board members are designated by specific holders of the preferred stock. The election of the remaining minority board members is submitted to a vote of the stockholders.

Preferred Stock

The Company’s certificate of incorporation, as amended, designates and authorizes the Company to issue 17,116,522 shares of preferred stock, of which 5,020,952 shares are designated as Series A Preferred Stock, 480,307 shares are designated as Series A-1 Preferred Stock, 1,584,493 shares are designated as Series A-2 Preferred Stock, 1,703,958 shares are designated as Series A-3 Preferred Stock, 4,846,370 shares are designated as Series B Preferred Stock, and 3,480,442 shares are designated as Series C Preferred Stock.

9. STOCK BASED COMPENSATION

2018 Equity Incentive Plan

The amounts of stock based compensation expense recorded in the Company’s condensed consolidated statements of operations and comprehensive loss were as follows (in thousands):

Total stock based compensation |  | $ | 11,614 |  |  |  | 4,603 |

F-44

##### Table of Contents

During the six months ended June 30, 2025, the Company approved modifications to certain incentive stock option awards in connection with the termination of service of an employee. These modifications resulted in an extension of the post-termination exercise period for vested awards and a change of vesting conditions for unvested awards. As a result of these modifications, the Company recorded additional stock based compensation of $3,799 during the period.

As of June 30, 2025 and December 31, 2024, the total number of shares of common stock that may be issued under the 2018 Plan was 3,930,962, of which 215,289 and 720,584, respectively, remained available for future grant.

10. INCOME TAXES

During the six months ended June 30, 2025 and 2024, the Company recorded $327 and $55 of tax expense, respectively, representing an effective tax rate of 0.2% and 0.1%, respectively. For the six months ended June 30, 2025 and 2024, the provision for income taxes differed from the United States federal statutory rate primarily due to a foreign tax provision on foreign taxable earnings and existence of a valuation allowance against net deferred U.S. and state tax assets.

11. NET LOSS PER SHARE

Net loss per share basic and diluted net loss per share attributable to common stockholders was calculated as follows (in thousands, except share and per share amounts):

|  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |
Numerator: |  |  |  |  |  |  |  |
Net loss |  | $ | (158,694 | ) |  |  | (124,137 | )
PIK dividend on Preferred Stock |  |  | (24,540 | ) |  |  | (12,952 | )
Net loss attributable to common stockholders |  |  | (183,234 | ) |  |  | (137,089 | )
Denominator: |  |  |  |  |  |  |  |
Weighted average common shares outstanding, basic and diluted |  |  | 7,167,070 |  |  |  | 7,072,532 |
Net loss per share, basic and diluted |  | $ | (25.57 | ) |  |  | (19.38 | )

The Company’s Series B and Series C Preferred Stockholders are entitled to cumulative dividends based on their stated value. As such, the Company calculates its net loss attributable to common stockholders by adjusting its net loss for the aggregate cumulative dividends that had accrued since the original issuance dates in the period in which the Preferred Stockholders became legally entitled to such dividends.

The Company’s potentially dilutive securities, which include stock options to purchase common stock and Preferred Stock, have been excluded from the computation of diluted net loss per share as the effect would be anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The following potentially dilutive securities have been excluded from the calculation of diluted net loss per share due to their anti-dilutive effect:

|  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |
Convertible Series A preferred stock |  |  | 8,789,710 |  |  |  | 8,789,710 |
Convertible Series B preferred stock |  |  | 3,982,998 |  |  |  | 3,982,998 |
Convertible Series C preferred stock |  |  | 2,856,966 |  |  |  | — |
Options to purchase common stock |  |  | 3,188,324 |  |  |  | 2,438,923 |
|  |  | 18,817,998 |  |  |  | 15,211,631 |

12. SEGMENT REPORTING

The Company has one operating and reportable segment – Development and Manufacturing Electric Aircrafts. The Company determined its reportable segment using the management approach based on how the chief operating decision maker (“CODM”) evaluates the business. Substantially all Company’s fixed assets are located in the United States and all of the Company’s revenue is generated in the United States. The company’s foreign operations consist of expenses associated with engineering and related supporting administrative services.

The Company’s CODM is its Chief Executive Officer. As the Company has a single reportable segment and is managed on a consolidated basis, the measure of segment profit or loss is consolidated net loss as reported in the consolidated statements of operations and comprehensive loss. The CODM reviews the financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. The CODM does not use any segment asset measures to assess performance and decide how to allocate resources. The Company does not have intra-entity sales or transfers.

The Company’s reportable segment information was as follows (in thousands):

|  | Six Months Ended June 30, |
|  | 2025 |  |  | 2024 |
Revenues |  | $ | 15,565 |  |  |  | 7,589 |

Item 13. Other Expenses of Issuance and Distribution.

The following table sets forth an itemized statement of the amounts of all expenses (excluding underwriting discounts and commissions) payable by us in connection with the registration of the Class A common stock offered hereby. With the exception of the SEC Registration Fee, FINRA Filing Fee and NYSE listing fee, the amounts set forth below are estimates.

Item 14. Indemnification of Directors and Officers.

Section 145 of the DGCL provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement in connection with specified actions, suits and proceedings, whether civil, criminal, administrative, or investigative, other than a derivative action by or in the right of the corporation, if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification extends only to expenses, including attorneys’ fees, incurred in connection with the defense or settlement of such action and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation’s certificate of incorporation, bylaws, disinterested director vote, stockholder vote, agreement or otherwise.

Our Amended and Restated Certificate of Incorporation provides that a director will not be liable to the Company or its stockholders for monetary damages to the fullest extent permitted by the DGCL. Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. In addition, if the DGCL is amended to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the Company, will be limited to the fullest extent permitted by the amended DGCL. Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that the Company will indemnify, and advance expenses to, any officer or director to the fullest extent authorized by the DGCL.

We have obtained directors’ and officers’ insurance to cover our directors, officers and some of our employees for certain liabilities. In addition, we intend to enter into indemnification agreements with our current and future directors and officers containing provisions that are in some respects broader than the specific indemnification provisions contained in the DGCL. The indemnification agreements will require us, among other

II-1

##### Table of Contents

things, to indemnify our directors and officers against certain liabilities that may arise by reason of their status or service as directors or officers and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified.

The Underwriting Agreement (Exhibit 1.1 hereto) provides for indemnification by the underwriters of the registrant and its executive officers and directors, and by the registrant of the underwriters, for certain liabilities, including liabilities arising under the Securities Act.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 15. Recent Sales of Unregistered Securities.

Set forth below is information regarding securities sold by us within the past three years that were not registered under the Securities Act. None of these transactions involved any underwriters, underwriting discounts or commissions or any public offering. Also included is the consideration, if any, received by us for such securities and information relating to the section of the Securities Act, or rule of the SEC, under which exemption from registration was claimed.

Item 17. Undertakings.

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

| (1) | For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

| (2) | For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
