New in FY2025

As of December 31, 2025, we incurred a net loss of $618.2 million, and we have incurred a net loss of approximately $2.3 billion since inception.
We expect to continue incurring operating and net losses each quarter until at least the time we begin generating significant revenues from our planned lines of business.
Even if we successfully launch our planned lines of business, there can be no assurance that they will be financially viable.
We expect losses could increase as we develop and expand operations, including to: • design, develop, and certify our aircraft in the United States and other countries; • design and develop UAM networks and operations; • expand our business lines and operations, including our defense program, operations at Hawthorne Airport, and aviation services and technologies; • engage third parties on the design, development, manufacturing, certification and marketing of our products and services; • attract, retain and motivate talented employees; • expand our aircraft manufacturing capabilities and manufacture an inventory; • build inventories of parts and components for our aircraft; • expand design, development and servicing capabilities; • increase sales and marketing activities and develop distribution infrastructure; and • develop pilot training programs.
We may also be unable to manage growth effectively, which could strain resources and create operational challenges such as hiring, training, and managing personnel, distracting management, and harming our brand and financial results.
Expansion may require additional office space, infrastructure, personnel, and increased insurance coverage.
We expect insurance needs and costs to rise as we build production facilities, manufacture aircraft, establish commercial operations, add routes, increase flight and passenger volumes, and expand into new markets.
It is too early to predict the impact of commercial eVTOL operations on insurance costs, which may adversely affect our business, financial condition, and results of operations.
Because these costs are expected before significant revenues, our losses in future periods are expected to be significant.
We are developing our eVTOL aircraft and related UAM operations, which remain in the early stages, and our business and future prospects are subject to significant risks.
We were incorporated in October 2018 and have a limited operating history in designing, developing, and certifying eVTOL aircraft.Our eVTOL aircraft is in the development stage, and we depend on continued engagement with the FAA, DOT, and other regulators in the U.S. and certain other countries to obtain required certifications and authorizations for aircraft design, production, and operations.
Delays, interruptions, or unwillingness by regulatory agencies to engage with us could postpone or prevent certification.
For example, the U.S. government shutdown in 2025 disrupted operations at certain agencies, including the FAA.
Although we plan to develop Hawthorne Airport into our flagship Los Angeles hub, including for the LA28 Olympic Games, there can be no assurance we will receive all required approvals on time, if at all.
In addition, our competitors may obtain regulatory approvals in the U.S. or non-U.S. markets before we do.
Our operations also depend on the performance and availability of a Midnight aircraft platform, and any delays, defects, or grounding of this aircraft could significantly disrupt our business.
In addition, we may face airspace integration and operational constraints, including airspace capacity limits, air traffic control restrictions, vertiport availability, and local operating limitations, which could reduce aircraft utilization, limit the number of flights we can operate, and adversely affect our business and the scaling of our planned operations.
We and our partners may not be able to obtain necessary production certificates, ramp up manufacturing, or develop supply chains capable of meeting quality, price, engineering, design, target aircraft specifications, and production standards, as well as required production volumes.
We face significant challenges in the following areas, any of which could harm our business: • designing, certifying, manufacturing, and operating safe, reliable, and quality aircraft that meet intended use cases and target aircraft specifications; • obtaining and maintaining timely regulatory approvals for manufacturing, marketing, selling, operating UAM networks, or conducting defense-related programs; • building and protecting a respected brand and expanding our customer base; • marketing, selling, and servicing our aircraft and other technologies; • maintaining spare parts availability and customer support; • scaling manufacturing and operations efficiently; • managing growth effectively; • obtaining and maintaining adequate facilities and infrastructure; • attracting, retaining, and motivating skilled employees; and • adapting to technological change, competitive pressures, market trends, and evolving global regulations.
As an organization, we have no experience in volume aircraft manufacturing and we may be unable to scale our production to meet future demand or achieve targeted, cost, quality and delivery metrics.
Some of our current and potential competitors are larger, have more experience in the aerospace industry or have substantially greater resources, enabling them to develop technologies faster, promote and sell offerings more effectively.
In particular, our competitors may receive FAA or foreign government certifications for their eVTOL aircraft before we are able to do so.
Competitors may also form strategic partnerships that enhance their capabilities, and some foreign competitors could benefit from subsidies or protective measures, placing us at a competitive disadvantage.
We are developing aircraft and related services intended to support multiple use cases and market entry strategies, which may not achieve our anticipated benefits.
For example, through our Launch Edition program, we are offering aircraft, services and technologies to governments and customers to support the commercialization of our Midnight aircraft in markets outside the U.S., including early trial operations, pilot training, maintenance and certification support.
Agreements with program partners remain conditional, and there is no assurance we will execute definitive agreements timely, or at all.
In the U.S., we have applied for participation in the eIPP, but selection is not guaranteed.
If selected, we plan to conduct trial operations in participating cities.
Investments and expenses in early adopter markets and UAM networks, such as Southern California, including vertiport and charging infrastructure and customer-focused products and services, may not achieve anticipated competitive advantages or benefits.
We expect our capital expenditures and operating expenses to continue to be significant as we develop our aircraft and business, and to be driven primarily by aircraft development, certification, and customer demand.
We believe our current cash and cash equivalents and other sources of liquidity, including existing borrowings, will be sufficient to fund our current operating plan for at least the next 12 months.
However, we expect that over the coming years we will continue to make significant investments in our business, including development of aircraft and related technologies and services for our commercial and defense businesses, manufacturing ramp up, UAM network build out, development of Hawthorne Airport, and investments in our brand.
Our investments and expenses may be greater than currently anticipated or there may be unforeseen costs, and we may not succeed in acquiring sufficient capital to offset these expenses and achieve significant revenue generation.
We have a limited operating history and no historical data on the demand for our planned products and services.
We may need to seek equity or debt financing to fund future capital requirements.
Additionally, we also issue equity securities as consideration for products and services provided to us by certain vendors, which results in dilution to our stockholders.
Our ability to obtain the necessary capital to carry out our current business plan is subject to a number of factors, including general economic and market conditions, as well as investor sentiment regarding our planned business.
If we are unable to raise sufficient capital, we may have to significantly reduce our spending and/or delay or curtail operations or planned activities.
Further, disruptions in the financial services sector, including liquidity constraints, bank failures, or counterparty insolvencies, could limit our access to cash and financial instruments.
The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations or our financial flexibility.

Gone since FY2024

As of December 31, 2024, we incurred a net loss of $536.8 million, and we have incurred a net loss of approximately $1.7 billion since inception.
We believe that we will continue to incur operating and net losses each quarter until at least the time we begin generating significant revenues from our planned lines of business.
Even if we are able to successfully launch our planned lines of business, there can be no assurance that such lines of business will be financially viable.
We expect the rate at which we will incur losses could be significantly higher in future periods as we: • continue to design, develop, manufacture, certify and market our aircraft; • continue to design and develop UAM networks; • initiate and develop our new defense program; • continue to utilize third parties to assist us with the design, development, manufacturing, certification and marketing of our aircraft and UAM network; • continue to attract, retain and motivate talented employees; • expand our aircraft manufacturing capabilities, including costs associated with the manufacturing of our aircraft; • build up inventories of parts and components for our aircraft; • manufacture an inventory of our aircraft; • expand our design, development and servicing capabilities; • increase our sales and marketing activities and develop our distribution infrastructure; • work with third-party partners to develop pilot training programs; and • increase our general and administrative functions to support our growing operations and operations as a public company.
Because we expect to incur the costs and expenses from these efforts before we receive any significant revenues with respect thereto, our losses in future periods are expected to be significant.
We are still developing our eVTOL aircraft, have not yet obtained governmental certification of our eVTOL aircraft under development and have yet to manufacture or deliver any aircraft to customers, which makes evaluating our business and future prospects difficult and increases the risk of investment in our securities.
We were incorporated in October 2018 and have a limited operating history in designing, developing, and working to certify an eVTOL aircraft.
Our eVTOL aircraft is in the development stage and we are still working with the FAA in the U.S. and equivalent government authorities in certain other countries in an attempt to obtain type certification of our eVTOL aircraft.
While we have received our Part 135 Air Carrier Certificate in the U.S. from the FAA and anticipate being able to obtain the remaining required authorizations and certifications, we may be unable to do so on our projected timeline or at all.
As an organization, we have no experience in volume manufacturing of aircraft.
Some of our current and potential competitors are larger and have substantially greater resources than we have and expect to have in the future.
As a result, those competitors may be able to devote greater resources to the development of their current and future technologies, the promotion and sale of their offerings, and/or offer their technologies at lower prices.
In particular, our competitors may be able to receive type, production or airworthiness certification from the FAA covering their eVTOL aircraft prior to us receiving such certifications.
Our current and potential competitors may also establish cooperative or strategic relationships amongst themselves or with third parties that may further enhance their resources and offerings.
Further, it is possible that domestic or foreign companies or governments, some with greater experience in the aerospace industry or greater financial resources than we possess, will seek to provide products or services that compete directly or indirectly with ours in the future.
Any such foreign competitor, for example, could benefit from subsidies from, or other protective measures by, its home country from which we may not be able to benefit.
We cannot assure you that we or our partners will be able to develop manufacturing and supply chain capabilities that will enable us to meet the quality, price, engineering, design and production standards, as well as the production volumes, required to successfully commercialize our aircraft.
You should consider our business and prospects in light of the risks and significant challenges we face as a new entrant into a new industry, including, among other things, with respect to our ability to: • design and manufacture safe, reliable and quality aircraft on an ongoing basis; • obtain the necessary regulatory approvals in a timely manner, including receipt of FAA certifications covering our aircraft and, in turn, any other government approvals necessary for manufacturing, marketing, selling and operating UAM networks or selling our aircraft, or for operating our defense program; • build a well-recognized and respected brand; • establish and expand our customer base; • successfully market not just our aircraft but also the other services we intend to provide, such as aerial ride sharing services; • successfully service our aircraft after sales and maintain a good flow of spare parts and customer goodwill; • improve and maintain our operational efficiency; • successfully execute our manufacturing and production model and maintain a reliable, secure, and scalable technology infrastructure; • predict our future revenues and appropriately budget for our expenses; • attract, retain and motivate talented employees; • anticipate trends that may emerge and affect our business; • anticipate and adapt to changing market conditions, including technological developments and changes in competitive landscape; and • navigate an evolving and complex global regulatory environment.
If we fail to adequately address any or all of these risks and challenges, our business may be harmed.
We expect our capital expenditures and operating expenses to continue to be significant in the foreseeable future as we develop our aircraft and business, and that our level of capital expenditures and operating expenses will be significantly affected by the aircraft development and certification process as well as subsequent customer demand for our aircraft.
We believe our current cash and cash equivalents and other sources of liquidity, including borrowings under our Credit Agreement, will be sufficient to fund our current operating plan for at least the next 12 months.
However, we expect that over the coming years we will continue to make significant investments in our business, including development of our aircraft and related technologies, ramping up manufacturing, building out our UAM networks, development of our defense program, and investments in our brand.
Our investments and expenses may be greater than currently anticipated or there may be investments or expenses that are unforeseen, and we may not succeed in acquiring sufficient capital to offset these expenses and achieve significant revenue generation.
We have a limited operating history and no historical data on the demand for our planned commercial and defense areas of our business.
We may need to seek equity or debt financing to finance a portion of our future capital requirements.
Our ability to obtain the necessary capital to carry out our business plan is subject to a number of factors, including general economic and market conditions, as well as investor sentiment regarding our planned business.
If we are unable to raise sufficient capital, we may have to significantly reduce our spending and/or delay or cancel our planned activities.
We might not be able to obtain any financing, and we might not have sufficient capital to conduct our business as projected, both of which could mean that we would be forced to curtail or discontinue our operations.
Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems.
If any of our counterparties to our financial instruments, including funds held in uninsured deposit accounts, credit agreements, letters of credit and certain other financial instruments, are impacted by liquidity issues and placed into receivership, we may be unable to access such funds.
If other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash, cash equivalents and investments may be threatened and could have a material adverse effect on our business and financial condition.
The incurrence of indebtedness would result in increased debt service obligations and could result in operating and financing covenants that would restrict our operations or our ability to pay dividends to our stockholders.
If we cannot raise additional capital when we need or want to, our operations and prospects could be negatively affected.
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, financial condition and results of operations could be harmed.
The markets for eVTOL aircraft are still in development, and our success in these markets is dependent upon our ability to effectively design, develop, and certify eVTOL aircraft and to market and gain traction of air UAM as a substitute for existing methods of transportation, as well as the effectiveness of our other marketing and growth strategies.
If the public, or in the case of our defense program, government entities, do not perceive eVTOL aircraft/UAM as beneficial or choose not to adopt eVTOL aircraft/UAM 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, financial condition and results of operations.
Growth of our business will require significant investments in our infrastructure, technology, and sales and marketing efforts.
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.
