SUMMARY RISK FACTORS

Investing in our common stock involves numerous risks, including the risks described in “Part I, Item 1A. Risk Factors” of this Annual Report. You should carefully consider these risks before making an investment. Below are some of these risks, any one of which could materially adversely affect our business, financial condition, results of operations, and prospects.

There is substantial doubt about our ability to continue as a going concern. We will need additional financing to execute our business plan, to fund our operations and to continue as a going concern.

We have incurred significant losses since our inception and we expect to incur significant expenses and continuing losses for the foreseeable future. We may not be able to achieve or maintain profitability or positive cash flows.

We will need to obtain sufficient financing or other capital to operate successfully. We may not be able to accurately predict our future capital needs, and we may not be able to obtain additional financing or access the capital markets to fund our ongoing operations and execute on our growth strategy on acceptable terms and conditions.

It is not possible to predict the actual number of shares we will need to sell under the Share Subscription Facility to GEM in order to draw down under such facility. Further, we may not have access to the full amount available under the Share Subscription Facility, or may not be able to draw down under the Share Subscription Facility in a timely manner (or at all) in order to meet our existing obligations.

We have previously defaulted on our debt and other obligations and there can be no assurance that we will be able to fulfill our obligations under any current or future indebtedness we may incur.

Our ability to utilize our NOLs and other carryforwards may be limited.

We may never realize the full value of our intangible assets or our long-lived assets causing us to record impairments that may negatively affect our financial condition and operating results.

Our contractual obligations could impair our liquidity and materially adversely affect our business, results of operations and financial condition.

Our management has identified material weaknesses in our internal controls over financial reporting.

If we experience harm to our reputation and brands, our business, financial condition and results of operations could be adversely affected.

We may not realize the expected return on our investment in SurfOS due to development delays, technical challenges, or lack of market acceptance, which could undermine our performance and competitive position.

The success of our business will be highly dependent on our ability to effectively market and sell our air mobility solutions as a substitute for alternative methods of transportation.

Our prospects and operations may be adversely affected by changes in consumer preferences, discretionary spending and other economic conditions that affect demand for our services.

We expect to face intense competition in the regional air mobility industry.

We will be dependent on our senior management team and other highly skilled personnel, and if we are not successful in attracting and/or retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

We may be unable to manage our future growth effectively, which could make it difficult to execute our business strategy.

The planned fully-electric and hybrid-electric powertrain solutions may not result in the operating cost savings we anticipate, which could negatively impact the future economics of our network operations as well as our ability to successfully sell and market our planned future Aircraft-as-a-Service initiative.

Our future fully-electric and hybrid-electric aircraft may require maintenance at frequencies or at costs which are unexpected and could adversely affect our business and operations.

The supply of pilots to the airline industry is limited and may negatively affect our operations and financial

condition. Increases in our labor costs, which constitute a substantial portion of our total operating costs, may have a material adverse effect on our business, financial condition and results of operations.

We are subject to legal, regulatory and physical risks associated with climate change, including the potential increased impacts of severe weather events on our operations and infrastructure.

We are exposed to operational disruptions due to maintenance.

Crashes, accidents or incidents of aircraft involving us or our competitors could have a material adverse effect on our business, financial condition and results of operations.

We, as well as our development and supply chain partners, have limited experience to date in the development and manufacturing of fully-electric and hybrid-electric powertrains and integrating those newly developed powertrains into existing certified airframes, and we may never develop or manufacture any fully-electric and hybrid-electric powertrains.

We are substantially dependent upon our relationships with our strategic partners, and we are or may be subject to risks associated with such strategic alliances. Our reliance on these arrangements, and the loss of any such alliances or arrangements or failure to identify future opportunities could affect our growth plans.

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

If we are unable to obtain and maintain access to adequate facilities and infrastructure in desirable locations, including securing access to key infrastructure such as airports, we may be unable to offer our service in a way that is useful to passengers.

Our operations are currently concentrated in a small number of metropolitan areas and airports which makes our business particularly susceptible to natural disasters, outbreaks and pandemics, growth constraints, economic, social, weather and regulatory conditions or other circumstances affecting these metropolitan areas.

The profitability of our current operations is dependent on the availability and pricing of aircraft fuel. Periods of significant disruption in the supply of aircraft fuel or elevated pricing could have a significant negative impact on our results of operations and liquidity.

If our third-party aircraft operators are unable to support our operations or the growth of our business, or we are unable to add alternative third-party aircraft operators to meet demand, our costs may increase and our business, financial condition and results of operations could be adversely affected.

We rely heavily on technology and automated systems to operate our business, and any failure of these technologies or systems could harm our business, results of operations and financial condition. A cyber-attack of these systems could disrupt our ability to deliver services to our customers and could lead to increased overhead costs, decreased sales and harm to our reputation.

If we fail to adequately protect our intellectual property rights, our competitive position could be impaired and we may lose market share, generate reduced revenue and incur costly litigation to protect our rights.

Our business will be subject to a variety of extensive and evolving laws and regulations, which may result in increases in our costs, disruptions to our operations, limits on our operating flexibility, reductions in the demand for air travel and competitive disadvantages.

Continued access to Essential Air Service revenue is of critical importance to us.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

We may fail to qualify for continued listing on the New York Stock Exchange (“NYSE”), which could make it more difficult for our stockholders to sell their shares.

Our management has limited prior experience in operating a public company.

PART 1

ITEM 1: BUSINESS

Overview

Surf Air Mobility Inc. (“Surf Air Mobility”, the “Company”, “us”, “we” or “our”) is a regional air mobility platform that aims to transform regional flying. The Company is currently comprised of its Air Mobility business, and has a goal of further developing and enhancing its service and technology offerings through its Air Technology business.

The Air Mobility business is an established regional air mobility platform providing scheduled service and an on-demand charter marketplace to passengers in the U.S. and globally. Current initiatives surrounding the Air Technology business seek to developproprietary aviation software, aircraft electrification powertrain technology and services to enable electrification across the regional air mobility sector.

The Company was incorporated in 2021 and became the ultimate parent of both Surf Air Global Limited (“Surf Air”) and Southern Airways Corporation (“Southern”) in July of 2023 following the Company’s public listing on the NYSE. For 2024, the Company served over 370,000 passengers with approximately 72,000 scheduled departures. We expect the combination of our legacy networks will continue to provide the basis for our expanded, nationwide regional Air Mobility business.

Our predecessor company, Surf Air, was formed in 2016 and prior to its reorganization into Surf Air Mobility, aimed to expand the category of regional air travel, connecting underutilized regional airports and private terminals to create a “shared private” customer experience and a high frequency “commercial-like” air service, using small turboprop aircraft. Surf Air provided both scheduled routes and on-demand charter flights operated by third parties that operate under Part 135 of Title 14 of the U.S. Code of Federal Regulations (“Part 135”). Surf Air drove the early stages of development of our current efforts to develop electrified powertrain technology, including the establishment of relationships with key commercial partners who, as a group, we believe can deliver novel hardware and software solutions that can make electrified flight possible for operators across the Part 135 industry, starting with our owned and operated fleet.

Our acquisition of Southern Airways in July 2023 has resulted in a combined regional airline network servicing U.S. cities across the Mid-Atlantic, Gulf South, Midwest, Rocky Mountains, West Coast, New England and Hawaii. Founded in 2013, Southern is one of the largest commuter airlines in the United States and the largest passenger operator of Cessna Grand Caravan EXs (“Cessna Caravans”) in the United States by scheduled departures. Southern has multi-year contracts with the U.S. federal government to operate Essential Air Service (“EAS”) routes, which helps small communities in the United States maintain a minimum level of scheduled air services.

At the heart of our strategy is our aim of commercializing green regional aviation at scale. We firmly believe that regional air mobility can displace driving from its predominant position in 100-500 mile travel. There are approximately 5,000 public use airports in the U.S. creating the possibility of a dense point-to-point air network using regional aircraft. We believe that electrified aircraft, which could boast lower operating costs and emissions could be the key to unlock this electrified air-mobility market.

Surf Air Mobility (through its subsidiary airlines Southern Airways and Mokulele Airlines) is one of the largest commuter airlines in the United States by scheduled departures, serving numerous communities across the U.S. mainland and Hawaii. In addition, we have commercial relationships with over 400 air operators that provide on-demand charter services to our customers. In the future, these charter operators will be ideal customers for our AI-enhanced software operating system, SurfOS, and for hybrid and electric aircraft, all of which we expect to launch, commercialize and/or scale through our relationships with Textron Aviation, Electra, REGENT and others.

Our Strategy

We have several strategic differentiators which form our competitive advantage in the regional air mobility market.

Scale: we are one of the largest commuter airlines in the U.S. by scheduled departures.

Experience: we have over a decade of experience operating in the highly regulated aviation industry and we have flown millions of passengers millions of miles.

7

Depth: we have deep – and unique – ties across the industry with exclusive relationships with Textron Aviation – manufacturer of the Cessna Caravan aircraft that we operate, and with Palantir Technologies a global leader in AI, enterprise data analytics, and business intelligence that we have partnered with to power the SurfOS operating system.

Reach: we have expansive reach and relationships with over 400 regional air operators who have operated charter flights via our marketplace and are expected to form the initial customer base of our SurfOS software. In addition, we have interline agreements with United, American, Alaska and Hawaiian Airlines that extend our reach to their combined 430 million annual passengers.

Technology: we are developing AI-enhanced software, in partnership with Palantir, to drive our growth and profitability and, in the future, we plan to offer this technology to other charter brokers, air operators, and aircraft owners.

Execution: we have brought together leaders and experts in aviation, software and electrification to help us synergistically execute our vision, drive profitable growth over time, and create shareholder value.

Given our leadership position in the regional air mobility sector, we believe we are uniquely qualified to understand the needs of industry participants and to develop software and hardware solutions to enhance efficiency, productivity, and profitability. Today, through our exclusive partnership with Palantir, we are developing an AI-enhanced software operating system, SurfOS. SurfOS is currently in the implementation phase across our Company, and we are already seeing improved productivity and efficiency through these tools. SurfOS aims to apply leverage to our commercial initiatives by streamlining our sales, sourcing, and distribution. Additionally, the software impacts critical functions of the airline operation such as crew scheduling, maintenance, and resource planning. We believe revenue management features such as dynamic pricing and flight distribution are key to maximizing revenue. Moreover, SurfOS is designed to empower a “connected aircraft,” which is expected to allow for near real-time insight into airplane health, maintenance needs, pilot performance, and flight tracking. We currently anticipate that we will begin rolling out SurfOS to launch customers in 2025, before widening distribution to other third-party operators, charter brokers, and owners over time.

The regional air mobility industry is expected to grow into a $75 billion to $115 billion global market by 2035. This market is expected to undergo massive transformation due to the emergence of new technologies such as electrification that seek to greatly reduce the cost of air travel, particularly for smaller regional planes that serve point-to-point routes from more convenient regional airports. In addition, electric and hybrid aircraft are expected to substantially reduce the carbon emissions of flying.

We believe Surf Air Mobility is uniquely positioned to lead the transformation of the regional air mobility industry. We intend to deploy electrified aircraft, when available, across our scheduled service routes. The Company is also pursuing Supplemental Type Certificates (“STCs”) for proprietary powertrain technology for the Cessna Grand Caravan aircraft. The Company has an exclusive sales and marketing relationship with the aircraft manufacturer, Textron Aviation, for distribution of electrified and hybrid powered aircraft, and we have MOU agreements with 7 operators globally with approximately 100 aircraft under management to potentially upgrade to our proprietary powertrains, once certified.

In addition, Surf Air Mobility’s platform will also help other electrification technologies go to market with access to the Company’s network and distribution potential. The Company is exploring relationships with other industry participants to bring innovative solutions to the regional air mobility market and accelerate the adoption of electrified aircraft potentially through the formation of joint ventures which may be separately capitalized.

Sources of Air Mobility Revenue

We generate revenue from two categories of air mobility services:

Scheduled Air Service - We generate revenue from operating scheduled commercial air service flights which are sold to the public primarily on a per seat basis, as well as through membership subscriptions.

8

Of our combined fleet of 57 aircraft, 46 are Cessna Caravans as of December 31, 2024. For the year ended December 31, 2024, our total fleet averaged approximately 190 daily departures. We believe we are one of the largest commuter air carriers by both size of Cessna Caravan fleet and number of scheduled departures of Cessna Caravans in the United States and we believe that in the future our scale could result in an increase in the number of average daily departures, fares and load factor compared to today. With our EP1 fully-electric powertrain expected to enter service shortly after we receive certification, which we anticipate to occur early in 2027, we believe we can be the first to operate an electrified fleet of aircraft in commuter operations.

We generate revenue from EAS revenue awards from the Department of Transportation (“DOT”).

The EAS program was put into place in the United States following the Airline Deregulation Act of 1978 to ensure that small communities continued to receive a minimal level of air service. EAS revenue awards are guaranteed revenue contracts issued by the DOT with revenue earned for completed flights. The EAS program subsidizes scheduled flights to connect underserved communities with larger airline hubs. These contracts help add predictable stability to Southern’s operations from both a route and revenue planning perspective. As of October, 1 2024, the EAS market size for annual contract subsidy rates was approximately $550 million.

We are a leader in securing and renewing EAS contracts, which we believe will be a critical differentiator as we work to expand our point-to-point short haul regional air mobility network. We work with key stakeholders in the communities in which we intend to serve as well as the DOT, and we have been able to tailor air travel solutions that are responsive to the key needs of these smaller, underserved communities. We have consistently been able to differentiate ourselves to win contracts by leveraging our large scale and depth of operational expertise to offer a low cost, highly reliable service proposal.

On-Demand - We generate revenue from on-demand flights created for customers on an ad-hoc, by request basis. A small number of the on-demand flights are operated on our fleet; the majority are delivered on third-party turboprops or small jets. For the year ended December 31, 2024, we generated revenue of $28.7 million from on-demand operations.

Today, we offer on-demand flight booking capabilities on our consumer platform enabled by our Surf Air mobile app, which is a capital light source of revenue.

We believe there is significant value to be created by leveraging our ability to serve both customers and operators within the regional flying ecosystem. We believe this will accelerate the demand for green regional flying. By enabling new demand through our digital marketplace operations and catalyzing new supply through new technology and financing solutions, we believe we can create an ongoing cycle of growth.

We plan to invest in creating a scheduled network connecting many of the underutilized regional airports in the United States. We have developed a regional air mobility network growth plan based on mobile device and various demographic data layers, which resulted in a network growth plan across approximately 30 U.S. regional networks with approximately 200 “tier 1” routes. We intend to pursue this plan using our own air operations and by leveraging third-party air operators.

We have extensive experience using third-party operators in our scheduled and on-demand operations. As a result, we believe we will have in-depth knowledge of the success factors and key challenges facing independent operators and can facilitate operator relationships by deploying our Aircraft-as-a-Service strategy. Aircraft-as-a-Service is the product we intend to offer operators. Aircraft-as-a-Service encapsulates bundling certain aircraft ownership related costs, potentially including leasing, insurance, powertrain maintenance and operating software purchase or rental for both conventional internal combustion and/or electrified aircraft to operators with the goal of creating a recurring revenue stream.

9

Customer Experience

We believe that the customer experience that we have developed is a meaningful differentiating advantage. We have strived to create an exceptional flying experience solving the greatest pain points of regional commercial flying. Through our large scale, we have a substantial customer service operation to support our travelers. We intend to give our customers a stress-free and time-saving airport and travel experience.

Seamless Booking. Our customer journey begins digitally through both our booking app and website, creating a personalized air travel experience. Using the mobile app and website, customers have access to a real-time digital marketplace, which we believe enhances and simplifies the user experience. Customers can conveniently purchase tickets on existing scheduled flights or create private charters. Customers have access to an array of available aircraft to meet various travel needs.

Local Airports & Private Terminals. We operate scheduled and on-demand flights in and out of small airports and private terminals. This provides our customers with the convenience of an accessible airport closer to their origin and/or destination and the convenience of a private terminal experience. We believe that local airports can transform into centers for pilot training, community job growth, and growth for local businesses.

Reduced Travel Times. Operating in and out of regional airports and private terminals reduces travel time for our customers. On a typical commercial flight, major airlines recommend customers arrive two hours before their departure time. In contrast, our customers typically only need to arrive 30 minutes before their flight, which results in our passengers saving approximately 1.4 to 1.6 hours per departure.

Hassle Free Experience. Our customer services and station teams offer all customers a direct touchpoint to help manage any travel related needs leading up to and on the day of the flight. Southern currently has interline agreements with major commercial airlines, including United Airlines, Inc., American Airlines, Inc., Alaska Airlines, Inc. and Hawaiian Airlines, Inc, which help coordinate baggage claim for customers who fly different airlines on various legs of their trip, assisting in a hassle free experience.

Pilot Shortage Solution. Recent and longer-term trends in the airline industry have led to a large disruption in the supply of available aircraft pilots. A reliable, predictable and adequate availability of pilots is an integral part of any airline’s ability to maintain consistent scheduling of their operations. We believe that our business model, flying under Part 135 regulation and using primarily single-engine aircraft, will enable us to be a solution to the pilot shortage by providing pilots to certify as first officers and captains earlier, and creating a talent pool that does not compete with other airlines that operate multi-engine aircraft. Furthermore, with our pilot partnership with SkyWest, we are able to ensure that hiring and retention costs are offset in part by promoting pilot career flow into the regional airline industry.

As we plan to transition to fully-electric flight, we believe we are well-positioned to manage programs designed for training pilots for any new requirements related to the operation of electrified aircraft. Through our combined leverage as suppliers of new electrified aircraft and facilitators of a pilot training pipeline, we believe we can create a program that helps to ensure an adequate supply of pilots for the introduction of electrified flight.

10

We believe that our current and future experience and knowledge, generated by operating our own large scheduled fleet and charter operation, combined with our partnerships and interactions with operators, brokers, lessors and OEMs puts us in a strong position to identify, create and commercialize the best electrification products and services for our evolving industry.

Government Regulation

The Company is subject to government regulation at local, state, national and international levels. The scope of these regulations is exceedingly broad, covering a wide range of subjects that includes, but is not limited to, those summarized below. Given the dynamic and rapidly evolving nature of the regulatory environment, the conduct of our business will always include a measure of risk and we may not be able to predict or control how new regulations might be written, or predict how existing regulations may be interpreted, or enforced.

Various aspects of our business, including scheduled and on-demand air service and electrification, are all impacted by interrelated but distinct regulatory frameworks.

Principal Domestic Regulatory Authorities

DOT

The U.S. Department of Transportation (the “DOT”) is the principal regulator of economic and consumer protection matters in the U.S. commercial aviation industry. The DOT licenses and oversees the operations of all carriers. This includes economic authority to conduct business as a type of air carrier, as well as consumer protection and insurance requirements that are applied to the conduct of such business. The DOT also oversees the marketing, sale and performance of public charter flights (charter flights which are sold by the seat) that may be arranged by an indirect air carrier (i.e., an entity that does not operate aircraft but contracts as a principal with a direct air carrier to do so on its behalf), for the purpose of offering its chartered flights to the public that will be performed by an identified direct air carrier at a predetermined date and time (in contrast to the on-demand, or as-needed/where-needed, character of certain of our services). The DOT oversees and regulates how airlines advertise and hold out services. The DOT also oversees the sale, holding out and arrangement of single-entity charter air transportation (charter of the entire capacity of an aircraft, in contrast to public charter flights which are sold by the seat). The DOT has authority to enforce laws and regulations against engaging in “unfair” or “deceptive” practices in the sale or provision of air transportation. The DOT promulgates and enforces various other consumer protection laws and regulations to which we are subject, including requirements related to non-discriminatory access to air transportation for disabled passengers, data reporting, recordkeeping, advertising and ticket sales, among others. The DOT is also responsible for monitoring and assuring that U.S. air carriers remain fit, willing and able at all times to provide the services for which they are licensed, and that such carriers qualify continuously as citizens of the United States within the meaning of U.S. aeronautical laws and regulations.

The Company is subject to U.S. laws regarding privacy of passenger and employee data, including as enforced by the DOT, that are not consistent in all jurisdictions where we operate and which are continually evolving, requiring ongoing monitoring and updates to our privacy and information security programs. Although we dedicate resources to manage compliance with privacy and information security obligations, the challenging and uncertain regulatory environment may pose material risks to our business, including increased operational burdens and costs, regulatory enforcement and legal claims or proceedings.

FAA

The Federal Aviation Administration (“FAA”) is an operating administration of the DOT and the principal regulator of safety matters in the U.S. aviation industry.

11

the oversight and operational control of air carriers by their accountable managers, directors of operations, directors of maintenance and other key personnel.

TSA

The Transportation Security Administration (the “TSA”) is an administration within the U.S. Department of Homeland Security which issues security programs to air carriers and ensures that air carriers operate in a manner consistent with any security program and other requirements issued to the carrier.

Facilities

Our headquarters is located in a leased 5,500 square foot facility in Hawthorne, California. The lease of this facility expires in August 2026.

Southern’s headquarters is located in a leased workspace in Palm Beach, Florida. The lease of this facility expires in April 2025.

In February 2025, the Company relocated its air operations center to Addison, Texas. The lease of this facility expires in January 2028.

Human Capital/Team

As of December 31, 2024, we had 703 employees, of which 556 were full-time and 147 were part-time.

We have not experienced any work stoppages and consider our relationship with our employees to be good. Our employees are divided across various core business functions, including operations, sales and marketing, research and development, customer service and finance and administration.

None of our employees are subject to a collective bargaining agreement or represented by a labor union.

Commitment to Environmental, Social and Governance (“ESG”) Leadership

We are seeking to build a regional air mobility ecosystem that will sustainably connect communities. We intend to accelerate the adoption of green flying, bringing electrified aircraft to market at scale in order to substantially reduce the cost and environmental impact of regional flying. In so doing, we believe we can make a meaningful contribution to tackling the dual challenges of congestion and climate change. We are working to build a dedicated, and inclusive workforce to achieve this goal while striving to adhere to best practices in risk assessment, mitigation and corporate governance.

Our ESG efforts consist of focusing on the following:

Environmental. Being a good steward of the natural environment through the production and development of innovative designs that reduce resource use and energy consumption.

Social. Promoting inclusion, while underpinning all of our activities with a core focus on health and safety.

Governance. Upholding our commitment to ethical business conduct, integrity and corporate responsibility, and integrating strong governance and enterprise risk management oversight across all aspects of our business.

Inclusion

We work diligently to create an inclusive work environment. We strive to provide equal opportunities for growth, success, promotion, learning and development, and aim to achieve parity in the way we organize, assign and manage projects in a way that provides equal opportunities for all. We are focused on building support across all teams and individuals, with the aim that everyone has a voice, and treats each other with respect.

Intellectual Property

Our ability to protect our material intellectual property is important to our business. We seek to protect our intellectual property (including our technology and confidential information) through a combination of trademarks and trade secret protections, as well as contractual commitments and security procedures. We generally require employees and consultants to enter into confidentiality and assignment of inventions agreements and certain third parties to enter into nondisclosure agreements.

We regularly review our technology development efforts and branding strategy to identify and assess the protection of new intellectual property. We own certain trademarks important to our business, such as the “Surf Air” and “Mokulele Airlines” trademarks in the United States.

We currently own the “surfair.com” Internet domain-name registration and the “iflysouthern.com” and “mokuleleairlines.com” domain-name registrations. The regulation of domain names in the United States is subject to change. Regulatory bodies could establish additional top-level domains, appoint additional domain name registrars or modify the requirements for holding domain names. As a result, we may not be able to acquire or maintain all domain names that use the name “Surf Air” or “Southern” or are otherwise relevant to or descriptive of our business.

We have chosen to rely primarily on copyright and trade secret law in order to protect our software and have chosen not to register any copyrights in these works. However, in the United States, copyrights must be registered in order to bring a claim for infringement and to obtain certain types of remedies. Even if we decide to register a copyright in our software to bring an infringement action, the remedies and damages available to us for unauthorized use of our software may be limited.

Intellectual property laws, contractual commitments and security procedures provide only limited protection, and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed or misappropriated. Further, trade secrets, know-how and other materials may be independently developed by our competitors or revealed to the public or our competitors and no longer provide protection. In addition, intellectual property laws vary from country to country. We may therefore be unable to protect certain of our technology, brands or other intellectual property in the U.S. or other jurisdictions.

We regularly review our development efforts to assess the existence and patentability of new inventions, and we are prepared to file patent applications when we determine it would benefit our business to do so.

Privacy and Data Protection

There are many requirements regarding the collection, use, transfer, security, storage, destruction and other processing of personally identifiable information and other data relating to individuals. Because our technology platform is an integral aspect of our business, compliance with laws governing the use, collection and processing of personal data is necessary for us to achieve our objective of continuously enhancing the user experience of our mobile application and marketing site.

We receive collect, store, process, transmit, share and use personal information and other customer data, including passenger data, and we rely in part on third parties that are not directly under our control to manage certain of these operations and to receive, collect, store, process, transmit, share and use such personal information, including payment information. A variety of federal, state, local, municipal and foreign laws and regulations, as well as industry standards (such as the payment card industry standards) govern the collection, storage, processing, sharing, use, retention and security of this information.

Corporate Information

We were originally founded in 2011 and incorporated in 2021 in Delaware. Our principal executive offices are located at 12111 S. Crenshaw Blvd., Hawthorne, CA 90250, and our telephone number is (424) 332-5480. Our website address is www.surfair.com.

ITEM 1A: RISK FACTORS

You should carefully consider the risks described below in addition to the other information set forth in this Annual Report on Form 10-K, including the Management’s Discussion and Analysis of Financial Condition and Results of Operations section and the consolidated financial statements and related notes. If any of the risks and uncertainties described below actually occur or continue to occur, our business, financial condition and results of operations, and the trading price of our common stock could be materially and adversely affected. The risks and uncertainties described below are those that we have identified as material but are not the only risks and uncertainties we face. Our business is also subject to general risks and uncertainties that affect many other companies, including, but not limited to, overall economic and industry conditions and additional risks not currently known to us or that we presently deem immaterial may arise or become material and may negatively impact our business, reputation, financial condition, results of operations or the trading price of our common stock. Moreover, some of the factors, events, and contingencies discussed below may have occurred in the past, but the disclosures below are not representations as to whether or not the factors, events or contingencies have occurred in the past, and instead reflect our beliefs and opinions as to the factors, events, or contingencies that could materially and adversely affect us in the future.

Risks Related to Our Financial Position and Capital Requirements

There is substantial doubt about our ability to continue as a going concern. We will need additional financing to execute our business plan, to fund our operations and to continue as a going concern.

We have incurred losses from operations, negative cash flows from operating activities and have a working capital deficit. We are currently in default of certain excise and property taxes, as well as certain debt, tax and other contractual obligations as further described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” and “- Risks Related to Our Financial Position and Capital Requirements - We have previously defaulted on our debt and other obligations and there can be no assurance that we will be able to fulfill our obligations under any current or future indebtedness we may incur”. There can be no assurances that we can cure any defaults that remain outstanding, or if cured, that we will not default on future obligations.

Our success is largely dependent on the ability to raise debt and equity capital, increase our membership base, increase passenger loads, and continue to expand into regions profitably throughout the United States.

We have funded our operations and capital needs primarily through the net proceeds received from the issuance of various debt instruments, convertible securities and preferred and common share financing arrangements. A significant amount of funding to date has been provided by entities affiliated with a co-founder of the Company. We will need additional financing to implement our full business plan, including our plans to electrify our fleet, which is a core part of our growth strategy, and to service our ongoing operations. We are evaluating, and will continue to evaluate, strategies to obtain additional funding for future operations. These strategies may include, but are not limited to, obtaining additional equity financing, issuing additional debt, entering into other financing arrangements, or restructuring of operations to grow revenues and decrease expenses.

If we are unable to raise sufficient financing when needed or events or circumstances occur such that we do not meet our strategic plans, we will be required to seek other sources of liquidity or to take additional measures to conserve liquidity, which could include, but are not necessarily limited to, restructuring our operations and possibly divesting all or a portion of our business, reducing spending on payroll, marketing, station rent and aircraft purchases necessary for our planned network, altering or scaling back development plans, including plans to equip regional airline operations with fully-electric and hybrid electric aircraft and reducing funding or deferring of capital expenditures, any of which could have a material adverse effect on our financial position, results of operations, cash flows and ability to achieve our business objectives. These factors raise substantial doubt about our ability to continue as a going concern.

Our prospects and ongoing business activities are subject to the risks and uncertainties frequently encountered by companies in new and rapidly evolving markets. Risks and uncertainties that could materially and adversely affect our business, results of operations or financial condition include, but are not limited to the ability to: (i) raise additional capital (or financing) to fund operating losses, (ii) refinance our current outstanding debt, (iii) maintain efficient aircraft utilization, primarily through the proper utilization of pilots and managing market shortages of maintenance personnel and critical aircraft components, (iv) sustain ongoing operations, attract and maintain customers, (vi) integrate, manage and grow recent acquisitions and new business initiatives, (vii) obtain and maintain relevant regulatory approvals, and (viii) measure and manage risks inherent to our business model.

15

Moreover, some of our vendors and suppliers likewise rely on capital raising activities to fund their operations and capital expenditures, which may be more difficult or expensive in the event of downturns in the economy or disruptions in the financial and credit markets (including as a result of the aforementioned factors that have impacted our operations). If such vendors or suppliers are unable to raise adequate capital to fund their business plans, they may not be able to comply with their obligations to us, which could have a material adverse effect on our business, financial condition and results of operations.

We have incurred significant losses since our inception and expect to incur significant expenses and continuing losses for the foreseeable future. We may not be able to achieve or maintain profitability or positive cash flows.

We have incurred significant losses since the Company’s inception. We incurred net losses of $74.9 million and $250.7 million for the years ended December 31, 2024 and 2023, respectively. We expect our operating expenses to increase over the next several years as we endeavor to increase our flight cadence, hire more employees and fund third-party research and development efforts relating to the development of our electrification technology, as well as due to macroeconomic factors such as rising inflation rates. 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 continue to have negative cash flow or losses resulting from our investment in increasing our member base and passenger loads or expanding our operations into regions throughout the United States, our business, financial condition and results of operations could be materially adversely affected. Going forward, our future losses may be larger than anticipated, and we may not achieve profitability when expected, or at all. Even if we achieve profitability, we may not be able to maintain or increase profitability.

The continued growth of our business will require significant investments in the development of our SurfOS software platform, fully-electric and hybrid-electric powertrains, our aircraft fleet, ground-based infrastructure, information technology and marketing and sales efforts. Our current cash flow has not been sufficient to support these needs to date. We have historically had negative cash flows and a working capital deficit, and have funded our operations and capital needs to date through the proceeds received from the issuance of various debt and equity instruments. Going forward, our ability to effectively manage growth and expansion of our operations will also require us to enhance various systems, including in relation to research and development, operations and internal controls and reporting. These enhancements will require significant capital expenditures and allocation of valuable management and employee resources. If our business does not generate the level of available cash flow required to support these operations and investments, and we are not able to determine an alternative solution to obtain the funding needed for our future operations, there may be a material adverse effect on our business, financial condition and results of operations.

It is not possible to predict the actual number of shares we will need to sell under the Share Subscription Facility to GEM in order to draw down under such facility. Further, we may not have access to the full amount available under the Share Subscription Facility, or may not be able to draw down under the Share Subscription Facility in a timely manner (or at all) in order to meet its existing obligations.

Pursuant to the Share Purchase Agreement with GEM Global Yield LLC SCS, as amended, (the “Share Subscription Facility”), upon the terms of and subject to the satisfaction of certain conditions, we have the right from time to time at our option to direct GEM to purchase up to a specified maximum amount of shares of our common stock, up to a maximum aggregate purchase price equal to $400 million over the term of the Share Subscription Facility. We may request advances from GEM (“GEM Advances”) at any time in an aggregate amount of up to $100 million, consisting of incremental advances of up to $25 million each provided that the first GEM Advance may not exceed $7.5 million without the consent of GEM. Any GEM Advance will reduce amounts that we can request for future draw downs. We have drawn upon the GEM Advances in 2024 and may continue to draw upon the GEM Advances in 2025 to augment our capital resources to address our capital needs.

The failure to satisfy the specified conditions under the Share Subscription Facility may result in our inability to request any or all of the GEM Advances or other draw downs pursuant to the Share Subscription Facility. In addition, upon requesting any GEM Advance under the Share Subscription Facility, we have agreed to deposit into escrow an amount of shares of common stock equal to two times the number of shares of common stock set out in the applicable advance request for a GEM Advance. There can be no assurances that we will be able to accurately estimate the number of shares of our common stock to be deposited since we will need to determine this number prior to the trading period of our common stock that will determine the actual purchase price for a GEM Advance. GEM will not be obligated to (but may, at its option, choose to) purchase shares of our common stock to the extent such purchase would result in

16

beneficial ownership (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder) by GEM, together with its affiliates, of more than 9.99% of our issued and outstanding common stock. Such beneficial ownership limitation will not apply to the GEM Advances. In addition, the amount requested for each draw down (other than a GEM Advance) available under the Share Subscription Facility may not exceed 400% of the average daily trading volume for the 30 trading days immediately preceding any draw down. There can be no guarantee that we will be able to access any or all of the GEM Advances or other draw downs available under the Share Subscription Facility. Our inability to access a portion or the remaining amounts available under the Share Subscription Facility, in the absence of any other financing sources, will have a material adverse effect on our business and our ability to operate as a going concern.

The purchase price per share to be paid by GEM for the shares of our common stock that we may elect to sell to GEM under the Share Subscription Facility pursuant to the GEM Advances or draw downs, if any, will fluctuate based on the volume weighted average trading price of our common stock during the applicable period for each purchase made pursuant to the Share Subscription Facility. Accordingly, it is not possible to predict, prior to any such sales, the number of shares of our common stock that we will sell to GEM under the Share Subscription Facility, the purchase price per share that GEM will pay for shares purchased from us under the Share Subscription Facility, or the aggregate gross proceeds that we will receive from those purchases by GEM (other than a GEM Advance) under the Share Subscription Facility, if any. Therefore, sales to GEM by us in order to utilize the GEM Advance will, and any future draw downs under the Share Subscription Facility could, result in substantial dilution to the interests of other holders of its shares of our common stock.

Sales of shares of our common stock, if any, to GEM under the Share Subscription Facility will be determined by us from time to time in our sole discretion and will depend on a variety of factors, many of which are outside of our control, including, among other things, market conditions and the terms, conditions and limitations set forth in the Share Subscription Facility (subject to certain limitations on the obligation of GEM to purchase shares including, among other things, beneficial ownership limitations (other than in respect of the GEM Advances)). We may ultimately decide to sell to GEM all, some or none of the shares of our common stock that may be available for us to sell to GEM pursuant to the Share Subscription Facility. Depending on market liquidity at the time, resales of those shares by GEM may cause the public trading price of our common stock to decrease.

As a result of the above factors, it is possible that we may need to issue and sell more than the number of shares that we initially expect to issue to GEM under the Share Subscription Facility in order to receive aggregate gross proceeds equal to GEM’s $400 million total aggregate purchase commitment under the Share Subscription Facility, which could cause additional substantial dilution to holders of our common stock. The number of shares of our common stock ultimately offered for sale by GEM is dependent upon the number of shares of our common stock we ultimately sell to GEM under the Share Subscription Facility.

We have previously defaulted on our debt and other obligations and there can be no assurance that we will be able to fulfill our obligations under any current or future indebtedness we may incur.

As of December 31, 2024, we had $122.6 million in debt outstanding, representing principal related to term loans, related party promissory notes and convertible notes. The incurrence of existing or future indebtedness could have important consequences on our business, including, but not limited to:

increasing our vulnerability to general adverse economic and industry conditions;

requiring us to dedicate a substantial portion of our cash flow from operations to servicing our debt, thereby reducing the availability of cash to fund working capital, capital expenditures, acquisitions and investments and other general corporate purposes;

limiting our flexibility in planning for, or reacting to, challenges and opportunities, and changes in our businesses and the markets in which we operate; and

leading to the possibility of default on future debt obligations.

17

Our ability to service our debt will depend on our future operating performance and financial results, which may be subject to factors beyond our control, including general economic, financial and business conditions. If we do not have sufficient cash flow to service our debt, we may need to refinance all or part of our existing debt, borrow more money or sell securities or assets, some or all of which may not be available at acceptable terms or at all. In addition, we may need to incur additional debt in the future in the ordinary course of business. Our current debt and any future additional debt we may incur may impose significant operating and financial restrictions. A breach of any of these restrictions could result in a default. If a default occurs, the relevant lenders could elect to accelerate payments due. If our operating performance declines, or if we are unable to comply with any restrictions, we may need to obtain amendments to our existing debt documents or waivers from the lenders to avoid default. These factors could have a material adverse effect on our business.

Further, if there were an event of default under our debt instruments or a change of control, the holders of the defaulted debt could cause all amounts outstanding with respect to that debt to be due and payable immediately and may be cross-defaulted to other debt. Our assets or cash flow may not be sufficient to fully repay borrowings under our outstanding debt instruments if accelerated upon an event of default, and there is no guarantee that we would be able to repay, refinance or restructure the payments on those debt securities.

We have previously defaulted on various debt and other obligations. Further, we are currently in default of certain excise and property taxes. See the section titled “Liquidity and Going Concern” in Note 1, Description of Business in the accompanying consolidated financial statements for further information.

Our past financial results may not be a reliable indicator of our future results. Further, our results of operations may fluctuate significantly, which makes our future results of operations difficult to predict and could cause our results of operations to fall below expectations or any guidance it may provide.

Our past financial results may not be a reliable indicator of our future results, particularly given our expected move toward fully-electric and hybrid-electric powertrain technology. Further, our quarterly and annual results of operations may fluctuate significantly, which makes it difficult for us to predict our future results of operations. As a result, comparing our results of operations on a period-to-period basis may not be meaningful. Investors should not rely on our past results as an indication of our future performance.

This variability and unpredictability could also result in our failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or results of operations fall below the expectations of analysts or investors or below any forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our common stock could decline substantially. Such a stock price decline could occur even when we have met any previously publicly stated revenue or earnings guidance it may provide.

Loss carryforwards and certain other tax attributes to offset future taxable income for U.S. federal income tax purposes may be significantly limited due to various circumstances, including certain possible future transactions involving the sale or issuance of common stock, or if taxable income does not reach sufficient levels.

Our ability to use Net Operating Loss (“NOL”) carryforwards and certain other tax attributes will depend on the amount of taxable income we generate in future periods and, as a result, certain of our NOL carryforwards and other tax attributes may expire before we can generate sufficient taxable income to use them in full. In addition, our ability to use NOL carryforwards and certain other tax attributes to offset future taxable income may be limited if we experience an “ownership change” as defined in Section 382 of the Internal Revenue Code of 1986, as amended (“Section 382”). Potential future transactions involving the sale or issuance of common stock may increase the possibility that we will experience a future “ownership change” under Section 382. Such transactions may include the exercise of warrants, the issuance of common stock for cash, the conversion of any future convertible debt, the repurchase of any debt with common stock, the acquisition or disposition of any stock by a stockholder owning 5% or more of the outstanding shares of common stock, or a combination of the foregoing.

We may never realize the full value of our intangible assets or our long-lived assets causing us to record impairments that may negatively affect our financial condition and operating results.

In accordance with applicable accounting standards, we are required to test indefinite-lived intangible assets for impairment on an annual basis, or more frequently where there is an indication of impairment, and certain other assets for impairment where there is any indication that an asset may be impaired. We may be required to recognize losses in

18

the future due to, among other factors, extreme fuel price volatility, tight credit markets, government regulatory changes, decline in the fair values of certain tangible or intangible assets.

Our contractual obligations could impair our liquidity and materially adversely affect our business, results of operations and financial condition.

We have significant long-term lease obligations primarily relating to our aircraft fleet. As of December 31, 2024, we had 40 aircraft under operating leases, with an average remaining lease term of approximately 4.29 years. As of December 31, 2024, future minimum lease payments due under all long-term operating leases were approximately $17.3 million. Our future ability to pay our contractual obligations and our liquidity will depend on our operating performance, cash flow and our ability to secure adequate financing, which will in turn depend on, among other things, the success of our business strategy, U.S. and global economic conditions, the availability and cost of financing, as well as general economic and political conditions and other factors that are beyond our control. If our liquidity is materially diminished, there may be a material adverse effect on our cash flow available to fund working capital requirements, capital expenditures and business development efforts.

We may not be able to accurately predict our future capital needs, and we may not be able to obtain additional financing or access the capital markets to fund our ongoing operations and execute on our growth strategy on acceptable terms and conditions.

We will need to raise capital in the future to fund our operations and to execute on our anticipated growth strategy, including the development of our planned electrification technology. For example, the cost of aircraft is a significant portion of our operating costs and is subject to change. As part of our agreement with TAI, we have committed to the purchase of 90 Cessna Caravans over a five-year period beginning in 2024, with an option for up to 25 additional Cessna Caravans, which we believe are currently competitively priced, but which may increase in price pursuant to price escalation clauses by the time we execute the purchase. Historically, we have financed our operations and capital expenditures primarily through private financing rounds and the issuance of debt and equity. A significant amount of our funding to date has been provided by entities affiliated with a co-founder of the Company.

We may utilize the GEM Advances, as necessary, in 2025 to address our capital needs. We may also seek additional capital through a combination of equity and debt financings.

There are a number of factors that may limit our ability to raise financing or access capital markets in the future, including current and future debt and contractual obligations, our liquidity and credit status, our operating cash flows, market conditions in the aviation industry, U.S. and global economic conditions, the financial impact of global events such as wars and pandemics, the general state of the banking system and capital markets and the financial position of the major providers of aircraft and other aviation industry financing. Any additional financing required by us may not be available on terms acceptable to us, or at all. If we are unable to source financing on acceptable terms, or unable to source financing at all, our business could be materially adversely affected. If we are unable to raise sufficient funds, we will have to significantly reduce our spending, delay or cancel our planned activities or substantially change our corporate structure.

If, in the future, we raise additional funds by issuing equity securities (including the GEM Advances), convertible debt or other similar securities, investors may experience significant dilution of their ownership interest, and these newly issued securities may have rights senior to those of the holders of common stock. Our current and any future financing arrangements, that we may enter into from time to time, involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, and currently, and in the future, could impair our operational flexibility, including restricting our ability to pursue our business strategy, increase our expenses, require that our assets secure such debt, or provide for high interest rates, discounted conversion prices, or other unfavorable terms. Higher interest rates could increase debt service requirements on our current variable rate indebtedness, and on any debt we subsequently incur, and could reduce funds available for operations, future business opportunities or other purposes. If we need to repay debt during periods of rising interest rates, we could be required to refinance our then-existing debt on unfavorable terms or liquidate one or more of our assets to repay such debt at times which may not permit realization of the maximum return on such assets and could result in a loss. The occurrence of such events could materially and adversely affect our profitability, cash flows and results of operations. If we are unable to obtain additional financing, including the GEM Advances, when needed or on acceptable terms, we will need to restructure our operations, and possibly divest all or a portion of our business. We may be required to cease operations which could result in our stockholders losing all or most of their investment.

19

Agreements governing our debt obligations include financial and other covenants that provide limitations on our business and operations under certain circumstances, and failure to comply with any of the covenants in such agreements could adversely impact us.

Our current and any future financing agreements that we may enter into from time to time, contain certain affirmative, negative and financial covenants, and other customary events of default. Under certain circumstances, such covenants require us to maintain minimum liquidity levels, limit our ability to enter into certain strategic transactions, make certain investments, pay dividends and make certain other specified restricted payments. Certain covenants in our financing agreements are subject to important exceptions, qualifications and cure rights, including, under limited circumstances, the requirement to provide additional collateral or prepay or redeem certain obligations. In addition, certain of our financing agreements are cross-collateralized, such that an event of default or acceleration of indebtedness under one agreement could result in an event of default under other financing agreements. If we fail to comply with such covenants, if any other events of default occur for which no waiver or amendment is obtained, or if we are unable to timely refinance the debt obligations subject to such covenants or take other mitigating actions, the holders of our indebtedness could, among other things, declare outstanding amounts immediately due and payable and, subject to the terms of relevant financing agreements, repossess or foreclose on collateral, including certain of our aircraft or other assets used in our business. The acceleration of significant indebtedness or actions to repossess or foreclose on collateral may cause us to renegotiate, repay or refinance the affected obligations, and there is no assurance that such efforts would be successful or on terms we deem attractive. In addition, any acceleration or actions to repossess or foreclose on collateral under our financing agreements could result in a downgrade of any credit ratings then applicable to us, which could result in additional events of default or limit our ability to obtain additional financing.

Risks Related to Our Business and Industry

The market for regional air mobility has not been established with precision, is still emerging and may not achieve the growth potential we expect or may grow more slowly than expected.

The regional air mobility market is still emerging and has not been established with precision. It is uncertain to what extent market acceptance will grow, if at all. We have historically operated in a limited number of regional areas. The success of the regional markets in which we operate and the opportunity for future growth in such markets may not be representative of the potential market for regional air mobility in other regional areas. Our success will depend to a substantial extent on the willingness of commuters and travelers to widely adopt regional air mobility, particularly point-to-point versus the currently predominant hub-and-spoke industry configuration, as an alternative for ground transportation. Although we believe our ability to develop AI-enhanced software to drive our growth and profitability and, in the future, to offer to other charter brokers, air operators, and aircraft owners to improve their operating efficiencies, will be a key factor in our future growth, if we are unable to develop our software solutions to meet the needs of our commercial partners, the actual operating efficiencies from using our software are less than anticipated, or charter brokers, air operators and aircraft owners do not adopt our software, then the market for our offerings may not develop, may develop more slowly than we expect or may not achieve the growth potential we expect. In addition, although we believe our ability to develop and integrate hybrid-electric and electric technology with our commercial partners to present a cost-effective solution to address the needs of consumers in this market will also be a key factor to the success of our future growth, if the market that we seek to address does not perceive electrification as beneficial, or chooses not to adopt electrification as a result of concerns regarding safety, affordability, value proposition or for other reasons, then the market for our offerings may not develop, may develop more slowly than we expect or may not achieve the growth potential we expect. As a result, the number of potential customers using our future services and the number of operators adopting our planned fully-electric and hybrid-electric powertrains cannot be predicted with any degree of certainty, and we cannot provide assurance that we will be able to operate in a profitable manner in any of our current or targeted future markets. Any of the foregoing could have a material adverse effect on our business, financial condition and results of operations.

Our prospects and operations may be adversely affected by changes in consumer preferences, discretionary spending and other economic conditions that affect demand for our services.

Our business is concentrated on air mobility, which is vulnerable to changes in consumer preferences, discretionary spending and other market changes impacting luxury goods and discretionary purchases (including as a result of concerns regarding the impact of a global recession). The global economy has in the past, and may in the future, experience recessionary periods and periods of economic instability, such as uncertainty in the banking system, rising fuel costs and ongoing business disruptions and related financial impacts resulting from public health crises such as pandemics, including changes in inflation and interest rates, and disruptions in manufacturing, delivery and overall supply chain. In particular, as a result of the current international trade environment (including uncertainties in global trade policies,

potential escalation of tensions under the new U.S. administration, and the unpredictable impact of tariffs and trade restrictions), the conflict between Russia and Ukraine and any potential increase in hostilities in the Middle East and rising prices and interest rates, many market observers anticipate that the global economy could face a recession in the foreseeable future. During such periods, our customers have chosen not to make discretionary purchases or to reduce overall spending on discretionary purchases. Such changes could result in reduced consumer demand for air transportation, including our air mobility services, or could shift demand from our air mobility services to other methods of air or ground transportation for which we do not offer a competing service. If we are unable to generate demand or there is a future shift in consumer spending away from air mobility, there could be a material adverse effect on our business, financial condition and results of operations.

We expect to face intense competition in the regional air mobility industry.

The regional air mobility industry is still developing and evolving, but we expect it to be highly competitive. We have a number of competitors in the regional air mobility market. For example, we compete against existing on-demand mobility air travel services, as well as ground transportation alternatives. Additionally, for certain of our longer routes, we compete against providers, including legacy commercial airlines, which have larger aircraft. We compete against companies that use technology that differs from the technology we intend to deploy in our aircraft in the future. For example, we will likely compete against other companies that utilize and develop fixed-wing electrification aircraft as well as competitors that pursue electric vertical takeoff and landing aircraft. Our potential competitors may be able to devote greater resources to the development of their current and future technologies or the promotion and sale of their offerings, or offer lower prices. Our potential competitors also may establish cooperative or strategic relationships among themselves or with third parties, including regional or national airport operations that we rely on to offer our air mobility services, which may further enhance their resources and offerings. It is possible that domestic or foreign companies or governments, some with greater experience in the air mobility 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 could benefit from subsidies or other protective measures provided by its home country.

We believe our ability to compete successfully as an air mobility service will depend on a number of factors, which may change in the future due to increased competition, including the price of our offerings, consumer confidence in the safety of our offerings, consumer satisfaction for the experiences we offer and the routes, frequency of flights and availability of seats offered through our platform. If we are unable to compete successfully, there could be a material adverse effect on our business, financial condition and results of operations.

If we are not able to successfully enter into new markets, offer new routes and services and enhance our existing offerings, our business, financial condition and results of operations could be adversely affected.

Our growth will depend in part on our ability to successfully enter into new markets, create and introduce new routes, and expand our existing routes by adding more frequent flights. Significant changes to our existing routes or the introduction of new and unproven routes may require us to obtain and maintain applicable permits, authorizations or other regulatory approvals. If these new or expanded routes are unsuccessful or fail to attract a sufficient number of customers to be profitable, or we are unable to bring new or expanded routes to market efficiently, our business, financial condition and results of operations could be adversely affected. Further, new third-party aircraft operator or flier demands regarding our services, including the availability of superior routes or a deterioration in the quality of our existing routes, could adversely affect the attractiveness of our platform and the economics of our business and require us to make substantial changes to and additional investments in our routes or our business model.

Developing and launching new routes or enhancements to routes historically flown by us involves significant risks and uncertainties, including risks related to the reception of such routes by existing and potential future third-party aircraft operators and customers, increases in operational complexity, unanticipated delays or challenges in implementing such routes or enhancements, increased strain on our operational and internal resources (including an impairment of our ability to accurately forecast flier demand and the number of third-party aircraft operators using our platform) and negative publicity in the event such new or enhanced routes are perceived to be unsuccessful. Significant new initiatives have in the past resulted in similar operational challenges, and our growth strategy contemplates scaling our business rapidly, such as through acquisitions. In addition, developing and launching new routes and enhancements to our existing routes may involve significant upfront investment, such as additional marketing and terminal build-out, and such investments may not generate a return. Any of the foregoing risks and challenges could have a material adverse effect on our business, financial condition and results of operations.

21

Our long-term growth strategy includes the establishment of a regional air travel ecosystem, including the implementation of our Aircraft-as-a-Service initiative. This involves (1) expanding the existing platform and brand to become the commercialization path for current and future sustainable air mobility technology, including sustainable aviation fuel flights, (2) providing bundled aircraft leasing, powertrain maintenance and operating software for conventional internal combustion and, in the future, our planned electrified aircraft, (3) once developed and certified, selling or leasing our electrification technology to other operators regardless of which network they serve and (4) working in close partnership with selected aircraft manufacturers and manufacturers of components of fully-electric and hybrid-electric propulsion systems to design and build the technology required to develop, and apply to obtain STCs for, the fully-electric and hybrid-electric propulsion systems that we intend to develop with our commercial partners. This ecosystem is complex and involves risk at each stage of implementation. There can be no assurance that we will successfully implement each stage of our regional air travel ecosystem or that the establishment of this ecosystem will result in the market opportunities we anticipate, and our failure to successfully achieve part or all of this ecosystem could have a material adverse effect on our business, financial condition and results of operations.

If we experience harm to our reputation and brands, our business, financial condition and results of operations could be adversely affected.

We must continue to increase the strength of our reputation and brands as reliable, experience-driven and cost-effective air mobility providers in order to attract and retain qualified third-party aircraft operators and customers. In addition, our growth strategy includes, among other things, exploring complementary strategic mergers and acquisitions, as well as strategic partnerships, to expand our capabilities and market opportunities, all of which benefit from our reputation and brand recognition. The successful development of our reputation and brands will depend on a number of factors, many of which are outside of our control. Negative perception of our business or platform may have a material adverse effect on our reputation and brands, including as a result of:

complaints or negative publicity or reviews about us, our third-party aircraft operators or customers, our air mobility services, certain other brands or events we associate with or our flight operations policies (e.g., cancellation or baggage fee policies), even if factually incorrect or based on isolated incidents;

general safety concerns or specific perceptions of the safety and performance of certain types of aircraft, such as single-engine versus twin-engine aircraft or propeller-powered aircraft versus jet-powered aircraft, or if companies have policies that prevent them from utilizing our services due to the aircraft we operate;

changes to our flight operations, safety and security, data privacy or other policies that users or others perceive as overly restrictive, unclear or inconsistent with our values;

a failure to enforce our flight operations policies in a manner that users perceive as effective, fair and transparent;

illegal, negligent, reckless or otherwise inappropriate behavior by our customers, our third-party aircraft operators or other third parties involved in the operation of our business or by our management team or other employees;

flight delays or a failure to provide routes and flight schedules sought by customers;

actual or perceived disruptions or defects in our platform or other technology development, such as data privacy or security incidents, platform outages, payment processing disruptions or other incidents that impact the availability, reliability or security of our offerings;

litigation over, or investigations by regulators into, our operations or those of our third-party aircraft operators;

inadequate or unsatisfactory customer support service experiences;

negative responses by third-party aircraft operators or customers to new mobility offerings on our platform;

perception of our treatment of employees, contractors or third-party aircraft operators and our response to their sentiment related to political or social causes or actions of management;

disputes with any of our strategic partners;

problems in engagement with aircraft certification bodies or other regulators, communities, target demographics or other positioning in the market; or

22

any of the foregoing with respect to our competitors, to the extent such resulting negative perception affects the public’s perception of us or the aviation industry as a whole, and particularly if we are unable to adequately differentiate our brand, services and aircraft from others in the market.

In addition, changes we may make to enhance and improve our offerings, and to balance the needs and interests of our third-party aircraft operators and customers may be viewed positively from one group’s perspective (such as customers) but negatively from another’s perspective (such as third-party aircraft operators), or may be viewed negatively by either third-party aircraft operators or customers. If we fail to balance the interests of third-party aircraft operators and customers or make changes that they view negatively, third-party aircraft operators and customers may stop using our platform or take fewer flights, any of which could have a material adverse effect on our reputation, brands, business, financial condition and results of operations. Moreover, we may fail to adequately differentiate our brand, services, and aircraft from others in the market, which could impact our ability to attract customers or engage with other key stakeholders.

We may be unable to reduce end-user pricing for our air mobility services over time at rates sufficient to stimulate demand and drive expected growth for our air mobility services.

We may not be able to successfully reduce end-user pricing for our air mobility services over time to increase demand, address new market segments and develop a significantly broader customer base. Our end-user pricing may be most applicable to relatively affluent consumers who are willing to purchase our services, and we will need to address additional markets and expand our customer demographic in order to further grow our business. In particular, we intend for our air mobility services to be economically accessible to a broad segment of the population and appeal to the customers of existing on-demand mobility air travel services in addition to ground-based travel services, taxis and other methods of transportation.

Reducing end-user pricing in a timely manner is dependent on management accurately estimating the unit economics of our aircraft and the corresponding service. For example, if management’s estimates are inaccurate regarding utilization rates, demand elasticity, operating conditions, production costs, indirect cost of goods sold, landing fees, charging fees, electricity availability and/or other operating expenses, we may be unable to offer our service at end-user pricing that is sufficiently compelling to initiate the local network effects that we are predicting. This could negatively impact our reputation or brand and have a material adverse effect on our business, financial condition and results of operations.

From time to time, the aircraft industry has experienced periods of oversupply during which lease rates and aircraft values have declined, and any future oversupply could materially adversely affect our financial results and growth prospects.

Historically, the aircraft leasing business has experienced periods of aircraft oversupply. The oversupply of a specific type of aircraft is likely to depress the lease rates for and the value of that type of aircraft. The supply and demand for aircraft is affected by various cyclical and non-cyclical factors that are outside of our control, including:

passenger and air cargo demand;

fuel costs and general economic conditions;

geopolitical events, including war, prolonged armed conflict and acts of terrorism;

outbreaks of communicable diseases and natural disasters;

governmental regulation;

interest rates;

the availability of credit;

airline restructurings and bankruptcies;

manufacturer production levels and technological innovation;

manufacturers merging or exiting the industry or ceasing to produce aircraft types;

retirement and obsolescence of aircraft models;

reintroduction into service of aircraft previously in storage; and

23

airport and air traffic control infrastructure constraints.

In addition, due to the recent economic downturn and increased financial pressures, a number of operating lessors may be sold or merged with other operating lessors. The sale of any of these operating lessors (which may include a reduction in their aircraft fleets) and, in particular, their aircraft portfolios, could increase supply levels of used and older aircraft in the market.

These factors may produce sharp and prolonged decreases in aircraft lease rates and values and have a material adverse effect on our ability to lease or re-lease the commercial aircraft that we ultimately acquire and on our ability to sell such aircraft and parts at acceptable prices. Any of these factors could materially and adversely affect our financial results and growth prospects.

Any failure to offer high-quality customer support may harm our relationships with customers and could adversely affect our reputation, brands, business, financial condition and results of operations.

Through our marketing, advertising and communications with customers, we intend to set the tone for our brands as aspirational but also within reach. We strive to create high levels of customer satisfaction through the experience we provide in our terminal lounges and the support provided by our team and representatives. The ease and reliability of our offerings, including our ability to provide high-quality flier support, helps us attract and retain customers. Customers depend on our team to resolve any issues relating to our services, such as lost luggage and personal belongings, flight cancellations or scheduling changes. Our ability to provide effective and timely support is largely dependent on our ability to attract and retain skilled employees who can support customers and are sufficiently knowledgeable about our services. As we grow our business and improve our air mobility service platform, we will face challenges related to providing quality support at scale. Any failure to provide efficient flier support, or a market perception that we do not maintain high-quality support, could have a material adverse effect on our reputation, brands, business, financial condition and results of operations.

The success of our business will be highly dependent on our ability to effectively market and sell our air mobility solutions as a substitute for alternate methods of transportation.

We currently generate substantially all of our revenue from the sale of air transportation. Our success will depend in part on our ability to cost-effectively attract new customers, retain existing customers and increase utilization of our platform by existing customers. Our growth is highly dependent upon the adoption by charter brokers, air operators and aircraft owners of our SurfOS software solutions, the adoption by consumers of an enhanced form of mobility offered by our fully-electric and hybrid-electric aircraft, and those of others, once developed, and the growth of the regional air mobility industry. This market is new, rapidly evolving, characterized by rapidly changing technologies, price competition, additional competitors, evolving government regulation and industry standards, new aircraft announcements and changing consumer demands and behaviors. If customers do not broadly adopt this new form of mobility or are not willing to pay the prices we anticipate for our air mobility services, our business, including our planned Aircraft-as-a-Service initiative, may never materialize and there could be a material adverse effect on our prospects, financial condition and results of operations.

Passengers have a wide variety of options for transportation, including business aviation, commercial airlines, private aircraft operators, personal vehicles, rental cars, taxis, public transit and ridesharing offerings. To expand our customer base, we must appeal to new customers who have historically used other forms of transportation for regional travel. If customers do not perceive our air mobility services to be reliable, safe and cost-effective, or if we fail to offer new and relevant services and features on our platform, we may not be able to attract or retain customers or increase their utilization of our platform. If we fail to grow our customer base, retain existing customers or increase the overall utilization of our platform, there could be a material adverse effect on our business, financial condition and results of operations.

Our success in a given market will also depend on our ability to maintain and further develop our network of customers and accurately assess and predict customer demand and price sensitivity. Demand and price sensitivity may fluctuate based on a variety of factors, including macroeconomic factors, quality of service, negative publicity, safety incidents, corporate reporting related to safety, quality of customer service and support, perceived political or geopolitical affiliations and dissatisfaction with our products and offerings in general. If we fail to attract new customers or fail to accurately predict demand and price sensitivity, it may harm our financial performance, and our competitors’ services and products may achieve greater market adoption and as a result may grow at a faster rate than our service.

24

We expect that a large driver of customer demand for our service will be time savings when compared with alternative modes of transportation. If we are unable to deliver a sufficient level of time savings for our customers or if expected time savings are impacted by delays or cancellations, it may reduce demand for our services. If we are unable to generate demand or demand falls, there could be a material adverse effect on our business, financial condition and results of operations.

We will be dependent on our senior management team and other highly skilled personnel, and if we are not successful in attracting and/or retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

Our success will depend, in significant part, on the continued services of our senior management team and on our ability to attract, motivate, develop and retain a sufficient number of other highly skilled personnel, including finance, marketing, sales and technology and support personnel. The loss of any one or more members of our senior management team, for any reason, including resignation or retirement, could impair our ability to execute our business strategy and have an adverse effect on our business, financial condition and results of operations. If we are unable to attract and retain skilled employees to support our operations and growth, there could be a material adverse effect on our financial condition and results of operations.

As part of our growth strategy, we are engaging in, and may in the future engage in, acquisitions that could disrupt our business and have a material adverse effect on our financial condition.

We intend to explore potential strategic acquisitions of businesses, as well as strategic partnerships, to expand our capabilities and market opportunities, as well as the establishment of a wholly-owned or joint venture aircraft and powertrain financing company. There can be no assurance that any future acquisitions or partnerships will be consummated successfully, if at all. We may also not be successful in identifying appropriate targets for such transactions. In addition, we may not be able to continue the operational success of such businesses or successfully finance or integrate any businesses that we acquire or with which we form a partnership. We may have potential write-offs of acquired assets and/or an impairment of any goodwill recorded as a result of acquisitions. Furthermore, the integration of any acquisition, including the acquisition of Southern, or the establishment of a partnership or joint venture may divert management’s time and resources from our core business and disrupt our operations or may result in conflicts with our business. Any acquisition, partnership or joint venture may not result in anticipated synergies or cost savings over time, may reduce our cash reserves, may negatively affect our earnings and financial performance, to the extent financed with the proceeds of debt, may increase our indebtedness and to the extent financed with the proceeds of equity, and may result in dilution to our existing equity holders. We cannot ensure that any acquisition or partnership we make will not have a material adverse effect on our business, financial condition and results of operations.

We may be unable to manage our future growth effectively, which could make it difficult to execute our business strategy.

If our operations continue to grow as planned, of which there can be no assurance, we will need to expand our sales, marketing, operations and the number of aircraft operators with whom we do business. Our continued growth could increase the strain on our resources, and we could experience operating difficulties, including difficulties in hiring, training and managing an increasing number of employees. These difficulties may result in the erosion of our brand image, divert the attention of management and key employees and impact our financial condition and results of operations. In addition, in order to continue to increase our presence, we expect to incur substantial expenses as we continue to attempt to increase our route offerings, flight frequency, passenger terminal footprint and employee base. The continued expansion of our business may also require additional space for administrative support. If we are unable to drive commensurate growth, these costs, which include lease commitments, marketing costs and headcount, could result in decreased margins, which could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to the Development of the SurfOS Software Platform

25

We may not realize the expected return on our significant investment in SurfOS due to development delays, technical challenges, or lack of market acceptance, which could undermine our financial performance and competitive position.

We have invested, and will continue to invest, significant time, effort, and financial resources into the development and implementation of SurfOS, our AI-enhanced software operating system. The success of SurfOS is critical to our strategy of enhancing operational efficiency and providing advanced technological solutions to our customers. However, there are several risks associated with this initiative. The development of SurfOS involves complex software engineering and integration with our existing systems and operations. Any delays or technical challenges in the development process could postpone the deployment of SurfOS, potentially leading to increased costs and missed market opportunities. Additionally, unforeseen technical issues could arise, requiring further investment and resources to resolve. Even if SurfOS is successfully developed and deployed, its success depends on market acceptance and adoption by our customers and partners. If SurfOS does not meet the expectations of our customers or fails to deliver the anticipated benefits, we may not achieve the desired return on our investment. This could adversely affect our financial performance and competitive position.

The joint venture to develop SurfOS creates risks through technology dependence, potential partner misalignment, relationship challenges, and funding uncertainties that could significantly impact the company's business.

Our joint venture with Palantir to develop SurfOS and other software solutions introduces additional risks that could impact our business. The success of SurfOS is heavily reliant on Palantir's proprietary software platforms and their implementation engineering services. Any disruption in Palantir's ability to deliver these services, or any deterioration in our relationship with Palantir, could adversely affect the development and functionality of SurfOS. Additionally, any changes in Palantir's business strategy or priorities could impact their commitment to the joint venture. The joint venture requires close collaboration and alignment between us and Palantir. Any misalignment in strategic goals, operational processes, or management decisions could hinder the progress of SurfOS development and its subsequent commercialization. Furthermore, disagreements or conflicts between the parties could lead to delays, increased costs, or even the dissolution of the joint venture. The joint venture is expected to be capitalized by outside third-party investors. If we are unable to secure sufficient funding or if the capital raised is inadequate to support the development and commercialization of SurfOS, the project may face significant setbacks. Additionally, the allocation of resources between SurfOS and other business priorities could strain our financial and operational capabilities. In summary, while SurfOS represents a significant opportunity for innovation and growth, it also carries substantial risks related to its development, market acceptance, and the dynamics of our joint venture with Palantir. These risks could materially and adversely affect our business, financial condition, and results of operations.

Risks Related to the Development of Electrification Technology

We, as well as our development and supply chain partners, have limited experience to date in the development and manufacturing of fully-electric and hybrid-electric powertrains and integrating those newly developed powertrains into existing certified airframes, and we may never develop or manufacture any fully-electric and hybrid-electric powertrains.

Our business depends in large part on our ability to execute our plans to develop, produce, assemble, market, sell, install and service our fully-electric and hybrid-electric powertrain solutions. Our ability to develop and produce fully-electric and hybrid-electric powertrain solutions of sufficient quality and appeal to customers on schedule and at scale is unproven. We have no prior experience or operating history in the development and manufacturing of electrification technology. We have entered into agreements with development and supply chain partners, such as TAI and AeroTEC, who each have limited experience in the development and manufacturing of the fully-electric and hybrid-electric powertrains that we are planning to produce, as well as in the integration of this newly developed technology into existing certified airframes. Our fully-electric and hybrid-electric powertrains are currently in the developmental stage. We do not expect to successfully commercialize our first fully-electric powertrains before early 2027 and the hybrid-electric powertrains before the end of 2027, if at all. There can be no assurance as to whether our current or future third-party partners will be able to develop efficient, automated, low-cost production capabilities and processes and/or obtain reliable sources of component supply to allow us to meet the quality, price, engineering, design and production standards and production volumes required to successfully develop, manufacture and market our fully-electric and hybrid-electric powertrains before the end of 2027. Moreover, unlike the market for electric automobiles, the commercialization of electric and hybrid-electric aircraft remains unproven. Although we believe that the component technology to electrify small aircraft exists today, there is currently no other producer of fully-electric or hybrid-electric aircraft in the industry.

26

Any delay in the development, manufacture and launch of electrification technology could adversely affect our brand, operations and the delivery of our growth strategy, particularly if it results in a failure to expand our market share in the regional air mobility market as anticipated. Any such delays could require us to incur additional costs. Even if we and our third-party partners are successful in developing our fully-electric and hybrid-electric powertrains and reliably sourcing our component supply, we do not know whether we will be able to do so in a manner that avoids significant delays and cost overruns, including as a result of factors beyond our control such as problems with suppliers and vendors, force majeure events, delays in meeting commercialization schedules, or failure to satisfy the requirements of customers and potential customers. Any such failure could have a material adverse effect on our business, financial condition and results of operations.

As a new entrant into the nascent market of hybrid-electric and battery electric aircraft, we anticipate that we will face risks and significant challenges that would impact our ability to, among other things:

design and produce safe, reliable and quality fully-electric and hybrid-electric powertrains on an ongoing basis;

obtain necessary regulatory approvals in a timely manner, or at all;

build a well-recognized and respected brand;

attract and maintain core commercial partnerships;

establish and expand our customer base;

successfully service our aircraft after sales and maintain a good flow of spare parts and customer goodwill;

improve and maintain our operational efficiency;

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 our competitive landscape; and

navigate an evolving and complex regulatory environment.

If we fail to adequately address any or all of these risks and challenges, our business, financial condition and results of operations may be materially and adversely affected.

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

While we strive to be the first to market providing air mobility services with a hybrid-electric aircraft,we expect this industry to be increasingly competitive and it is possible that our competitors could get to market before us, either generally or in specific markets. The timing of our production ramp is dependent upon finalizing certain aspects of the design, engineering, component procurement, testing, build out and manufacturing plans in a timely manner, and our ability to execute these plans within the current timeline and upon regulatory approval by the FAA, which can be a lengthy and unpredictable process.

Even if we are first to market with fully-electric or hybrid-electric aircraft, we may not fully realize the benefits we anticipate, and we may not receive any competitive advantage or may be overcome by other competitors. New companies or existing aerospace companies may launch competing solutions, including fully-electric and hybrid-electric aircraft in the markets in which we intend to operate, or fully-electric or hybrid-electric aircraft utilizing different technologies such as hydrogen fuel cells, and obtain large scale capital investment, which may result in increased competition.

Additionally, our competitors may benefit from our efforts in developing consumer and community acceptance for hybrid-electric aircraft and air mobility, making it easier for them to obtain the permits and authorizations required to operate an air mobility service in the markets in which we intend to launch or in other markets. In the event we do not capture the first mover advantage that we anticipate, it could have a material adverse effect on our business, financial condition, results of operations and prospects.

27

The planned fully-electric and hybrid-electric powertrain solutions may not result in the operating cost savings we anticipate, which could negatively impact the future economics of our network operations as well as our ability to successfully sell and market our planned future Aircraft-as-a-Service initiative.

In developing our business strategy for future aircraft electrification and network expansion, we have assumed implementing fully-electric technology will result in operating cost savings of approximately 50% compared to current combustion powertrain technologies, with more limited range and payload characteristics, and hybrid-electric technology will result in operating cost savings of approximately 25% compared to current internal combustion powertrain technologies, while maintaining similar performance characteristics. If these assumptions change by a material amount, our network expansion plans could be negatively impacted and we would be unlikely to be able to develop significant future revenues and earnings from our planned Aircraft-as-a-Service initiative.

Our future fully-electric and hybrid-electric aircraft may require maintenance at frequencies or at costs which are unexpected and could adversely affect our business and operations.

Our future fully-electric and hybrid-electric aircraft will be highly technical products that will require maintenance and support. We are still developing our understanding of the long-term maintenance profile of the fully-electric and hybrid-electric aircraft, and if useful lifetimes are shorter than expected, this may lead to greater maintenance costs than previously anticipated. If our future fully-electric and hybrid-electric aircraft and related equipment require maintenance more frequently than we plan for or at costs that exceed our estimates, that would disrupt the operation of our service and could have a material adverse effect on our business, financial condition and results of operations.

Risks Related to Our Operations and Infrastructure

If we are unable to obtain and maintain access to adequate facilities and infrastructure in desirable locations, including securing access to key infrastructure such as airports, we may be unable to offer our service in a way that is useful to passengers.

Our air mobility service will depend on our ability to operate in desirable metropolitan and regional locations. This will require permits and approvals from federal, state and local regulatory authorities and government bodies and our ability to operate our service will depend on such permits and approvals, as well as our ability to lease and license access to passenger terminal infrastructure. We lease and license access to passenger terminal infrastructure, such as hangars, from airport operators in certain of the markets in which they operate. These lease agreements have termination dates ranging from two to three years, and often include the right to extend on a month to month basis. We may face competition for capacity at passenger facilities in our preferred locations, which may impact our ability to service customers effectively. We also cannot predict whether we will receive any such permits and approvals, whether we will receive them for desirable locations or whether we will receive them in a timely manner. If we are prohibited, restricted or delayed from developing and operating desirable locations, there could be a material adverse effect on our business.

Our operations are currently concentrated in a small number of metropolitan areas and airports which makes our business particularly susceptible to natural disasters, outbreaks and pandemics, growth constraints, economic, social, weather and regulatory conditions or other circumstances affecting these metropolitan areas.

We currently derive revenues from regional flights operated in Hawaii and the Mid-Atlantic, Gulf South, Rocky Mountains, West Coast and New England regions. As a result of this geographic concentration, our business historically has been particularly susceptible to natural disasters, outbreaks and pandemics, growth constraints, economic, social, weather and regulatory conditions or other circumstances applicable to metropolitan areas. A significant interruption or disruption in service at an airport where we have a significant volume of flights could result in the cancellation or delay of a significant portion of our flights and, as a result, could have an adverse effect on our business, financial condition and results of operations. In addition, any changes to local laws or regulations within key metropolitan areas that affect our ability to operate or increase our operating expenses in these markets could have a material adverse effect on our business, financial condition and results of operations.

Disruption of operations at airports, whether caused by natural disasters including tornados, hurricanes, floods, volcanic eruptions and earthquakes, and severe weather conditions, such as heavy rains, strong winds, dense fog, blizzards or snowstorms, or labor relations, utility or communications issues, power outages, or changes in federal, state and local regulatory requirements could have a material adverse effect on our business.

28

Our aircraft utilization may be lower than expected and our aircraft may be limited in performance during certain weather conditions. We are vulnerable to delays, cancellations or flight rescheduling, as we will rely on maintaining a high daily aircraft usage rate, and need to aggregate customers on our by-the-seat flights to lower direct costs to third-party operators.

Our aircraft may not be able to fly safely in poor weather conditions, including snowstorms, thunderstorms, lightning, hail, known icing conditions or fog. The aircraft models that we have flown to date and the smaller airports out of which they operate are more vulnerable to delays of this nature and we have experienced delays and disruptions as a result of extreme weather. Our inability to operate in these conditions in the future will reduce our aircraft utilization and cause delays and disruptions in our services. We intend to maintain a high daily aircraft utilization rate which is the amount of time our aircraft spend in the air carrying passengers. High daily aircraft utilization is achieved in part by reducing turnaround times at airports so we can fly more hours on average in a day. 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 will have a material adverse effect on our financial condition as well as cause passenger dissatisfaction.

Our success also depends on our ability to generate more revenue per flight by maintaining high customer utilization rates (i.e., the number of seats purchased on each flight). Customer utilization rates may be reduced by a variety of factors, including the introduction of new routes or schedules. In some cases, we may choose to offer flights with low customer utilization rates to increase or maintain customer satisfaction, brand recognition, and for marketing or other purposes. We have utilized monthly and annual commuter passes and annual corporate bulk purchasing options to increase our customer utilization rates in the past; however, these products may be less appealing following COVID-19.

While historically we have maintained daily aircraft and customer utilization rates sufficient to offset the costs we pay to operators, we may be unable maintain and increase utilization rates as our business grows and expands. The risk of delays, cancellations and flight rescheduling, which could negatively impact our utilization rates, may increase as we expand our business to include new markets and destinations, more frequent flights on current routes and expanded facilities.

The supply of pilots to the airline industry is limited and may negatively affect our operations and financial condition. Increases in our labor costs, which constitute a substantial portion of our total operating costs, may have a material adverse effect on our business, financial condition and results of operations.

Our pilots are subject to stringent pilot qualification and crew member flight training standards (“FAA Qualification Standards”), which among other things require minimum flight time for pilots and mandate strict rules to minimize pilot fatigue. The existence of such requirements effectively limits the supply of qualified pilot candidates and increases pilot salaries and related labor costs. Such requirements also impact pilot scheduling, work hours and the number of pilots required to be employed for our operations, all of which could have a material adverse effect our business, results of operation and financial condition.

We have a pilot pipeline agreement with SkyWest to hire, train and provide a pipeline of pilots for our operations and a potential subsequent transition into SkyWest’s operations, and we intend to continue this arrangement going forward. However, this potentially exposes us to a number of risks. This arrangement may not be sufficient to offset a significant or prolonged shortage of pilots, and we will be increasingly reliant on this partnership as we look to expand our operations. If this pipeline is unable to provide us with pilots in the expected numbers or at the appropriate times, or if the agreement with SkyWest were to be terminated, we would be required to incur significant labor costs to find replacement or substitute pilots, which would result in a material reduction in our earnings. If we are unable to find a sufficient supply of pilots to fly our routes, we may be forced to cancel flights. In addition, our competitors may seek to use this training program as a way to generate negative publicity about us, which could have a material adverse effect on our reputation, business and results of operation.

In addition, our operations and financial condition may be negatively impacted if we are unable to train pilots in a timely manner. Due to an industry-wide shortage of qualified pilots, driven by the flight hours requirements under the FAA Qualification Standards and attrition resulting from the hiring needs of other industry participants, pilot training timelines have significantly increased and stressed the availability of flight simulators, instructors and related training equipment. As a result, the training of our pilots may not be accomplished in a cost-efficient manner or in a manner timely enough to support our operational needs.

We are subject to legal, regulatory and physical risks associated with climate change, including the potential increased impacts of severe weather events on our operations and infrastructure.

We are subject to federal, state, and local laws and regulations relating to the protection of the environment and noise, including those relating to emissions to the air, discharges (including storm water and de-icing fluid discharges) to surface and subsurface waters, safe drinking water and the use, management, disposal and release of, and exposure to, hazardous substances, oils and waste materials. Certain legislative bodies and regulatory authorities are increasingly focused on climate change and have taken actions to implement additional laws, regulations, and programs intended to protect the environment. For example, the federal government, as well as several state and local governments, have implemented legislative and regulatory proposals and voluntary measures intended to reduce greenhouse gas emissions. Compliance with laws, regulations, and other programs intended to reduce emissions or otherwise protect the environment may require us to reduce our emissions secure carbon offset credits or otherwise pay for emissions, or make capital investments to modify certain aspects of our operations to reduce emissions. Future policy, legal, and regulatory developments relating to the protection of the environment, including modifications to or reversals of such developments, could increase our costs and have a material adverse effect on our operations. Additionally, we may be subject to risks associated with climate change litigation, and to avoid the risks associated with climate change litigation, we would be required to manage our climate impacts responsibly, which may result in considerable expenses being incurred.

Moreover, the potential physical effects of climate change, such as increased frequency and severity of storms, floods, fires, fog, mist, freezing conditions, sea-level rise and other climate-related events, could affect our operations, infrastructure and financial results. Operational impacts, such as the delay or cancellation of flights, could result in loss of revenue. In addition, certain of our terminals are in locations susceptible to the impacts of storm-related flooding and sea-level rise, which could result in costs and loss of revenue. We could incur significant costs to improve the climate resiliency of our infrastructure and otherwise prepare for, respond to, and mitigate such physical effects of climate change. We are not able to accurately predict the materiality of any potential losses or costs associated with the physical effects of climate change.

Our business may be adversely affected by union activities.

Although none of our employees are currently represented by a labor union, it is common throughout the airline industry generally for many employees to belong to a union, which can result in higher employee costs and increased risk of work stoppages. As we expand our business there can be no assurances that our employees will not join or form a labor union or that we will not be required to become a union signatory. We are also directly or indirectly dependent upon companies with unionized work forces, such as parts suppliers, and work stoppages or strikes organized by such unions could have a material adverse effect on our business, financial condition or results of operations. If a work stoppage occurs, it could delay the manufacture and sale of our performance hybrid-electric vehicles and could have a material adverse effect on our business, financial condition or results of operations.

Our or our third-party aircraft operators’ insurance may become too difficult or expensive to obtain. Increases in insurance costs or reductions in insurance coverage may have a material adverse effect on our financial condition and results of operations.

Hazards are inherent in the aviation industry and may result in loss of life and property, potentially exposing us to substantial liability claims arising from the operation of aircraft. Safe operation of aircraft is the responsibility of ourselves and our third-party operators who are held liable for accidents, thus incidents related to aircraft operation are covered by ours and our third-party operators’ insurance. We maintain general liability aviation insurance policies. Additionally, we maintain directors and officers insurance, as well as other insurance policies, and we believe our level of coverage is customary in the industry and adequate to protect against claims. A limited number of hull and liability insurance underwriters provide coverage for our third-party aircraft operators. Insurance underwriters are required by various federal and state regulations to maintain minimum levels of reserves for known and expected claims. However, there can be no assurance that our or third-party aircraft operators’ insurance policies will be sufficient to cover potential claims or that present levels of coverage will be available in the future at reasonable cost, or that underwriters have established adequate reserves to fund existing and future claims. Further, we expect our insurance needs and costs to increase as we grow our commercial operations, add routes, increase flight and passenger volumes and expand into new markets. It is too early to determine what impact, if any, the commercial operation of our future hybrid-electric aircraft will have on our insurance costs.

Accordingly, we may not have adequate insurance coverage. The successful assertion of one or more large claims against us that exceeds our available insurance coverage, or results in changes to our insurance policies (including

30

premium increases or the imposition of large deductible or co-insurance requirements), could have an adverse effect on our business. In addition, we cannot be sure that our existing insurance coverage will continue to be available on acceptable terms or that our insurers will not deny coverage as to any future claim.

The number of air medical or tourism accidents, as well as the number of insured losses within the commercial airline industry, and the impact of general economic conditions on underwriters may result in increases in premiums above the rate of inflation. If our third-party aircraft operators’ insurance costs increase, such operators are likely to pass the increased costs to us, which could cause us to increase the prices paid by our customers. Such cost increases could adversely affect demand for our services and harm our business. Additionally, under all aircraft operating agreements, our third-party aircraft operators have agreed to indemnify us against liability arising from the operation of aircraft and to maintain insurance covering such liability. However, there can be no assurance there will be no challenge to the indemnification rights or that the aircraft operator will have sufficient assets or insurance coverage to fulfill its indemnity obligations.

We may incur substantial maintenance costs as part of our leased aircraft return obligations.

Some of our aircraft lease agreements contain provisions that require us to return aircraft airframes and engines to the lessor in a specified condition or pay an amount to the lessor based on the actual return condition of the equipment. These lease return costs are recorded in the period in which they are incurred. On our financial statements, we estimate the cost of maintenance lease return obligations and accrue such costs over the remaining lease term when the expense is probable and can be reasonably estimated. Any unexpected increase in maintenance return costs may have a material adverse effect on our financial condition and results of operations.

We are exposed to operational disruptions due to maintenance.

Our fleet requires regular maintenance work, which can cause operational disruption. Our inability to perform timely maintenance and repairs could result in our aircraft being underutilized which could have an adverse effect on our business, financial condition and results of operations. For example, during 2023 we were required to perform additional maintenance and repairs due to unforeseen weather conditions and, to a larger extent, supply chain disruptions, which resulted in lower utilization of aircraft and a decrease in scheduled flight hours, which negatively impacted scheduled revenue. In addition, we have experienced an increase in maintenance as a result of an increase in flight hours on our aircraft, which resulted in an increase in maintenance and repair costs. A prolonged period of maintenance or repair work would result in disruptions to our routes lower revenues and/or increased costs. On occasion, airframe manufacturers or regulatory authorities may require mandatory or recommended modifications to be made across a particular fleet which may mean having to ground a particular type of aircraft. This may cause operational disruption to and impose significant costs on us. Furthermore, our operations in remote locations, where delivery of components and parts could take a significant period of time, could result in delays in our ability to maintain and repair our aircraft. Any such delays may pose a risk to our business, financial condition and results of operations. Moreover, as our aircraft base increases, our maintenance costs could potentially increase. We have no historical experience maintaining fully-electric and hybrid-electric powertrains. While we believe the newly developed powertrains will require reduced maintenance activity per flight hour, our operations could be negatively impacted if our assumptions on reliability or cost of maintenance prove incorrect.

The profitability of our current operations is dependent on the availability and pricing of aircraft fuel. Periods of significant disruption in the supply of aircraft fuel or elevated pricing could have a significant negative impact on our results of operations and liquidity.

Although our current operations and those of third-party aircraft operators, in the limited circumstances, such as operations in Hawaii, where we purchase fuel directly, are currently able to obtain adequate supplies of aircraft fuel, we cannot predict the future availability. Natural disasters (including hurricanes or similar events in the southeast United States and on the Gulf Coast where a significant portion of domestic refining capacity is located), political disruptions or wars involving oil-producing countries, economic sanctions imposed against oil-producing countries or specific industry participants, changes in fuel-related governmental policy, the strength of the U.S. dollar against foreign currencies, changes in the cost to transport or store petroleum products, changes in access to petroleum product pipelines and terminals, speculation in the energy futures markets, changes in aircraft fuel production capacity, environmental concerns and other unpredictable events may result in fuel supply shortages or distribution challenges in the future leading to volatile aircraft fuel pricing. Any of these factors or events could cause a disruption in or increased demands on oil production, refinery operations, pipeline capacity or terminal access and possibly result in diminished availability of aircraft fuel supply for our third-party aircraft operators. The impact of such events may limit our third-party aircraft

31

operators’ ability to perform our flights, which could result in loss of revenue and adversely affect our ability to provide our services.

Additionally, high fuel prices or significant disruptions in the supply of aircraft fuel could have an adverse effect on our financial condition and results of operations. During the years ended December 31, 2024 and 2023, our fuel expense was $14.0 million and $7.2 million, respectively. The timely and adequate supply of fuel to meet operational demand depends on the continued availability of reliable fuel supply sources as well as related service and delivery infrastructure. Although we have some ability to cover short-term fuel supply disruptions, we depend significantly on the continued performance of our third-party service providers to maintain supply integrity. Consequently, we can neither predict nor guarantee the continued timely availability of aircraft fuel throughout our operations.

Unsatisfactory safety performance of our aircraft could have a material adverse effect on our business, financial condition and results of operations.

While we intend to maintain operational processes designed to ensure that the design, testing, manufacture, performance, operation and servicing of our aircraft meet rigorous quality standards, there can be no assurance that we will not experience operational or process failures and other problems, including through flight test accidents or incidents, manufacturing or design defects, pilot error, cyber-attacks or other inadvertent or intentional acts or omissions, that could result in potential safety risks. Any actual or perceived safety issues may result in significant reputational harm to our business, in addition to tort liability, maintenance, increased safety infrastructure and other costs that may arise. Such issues could result in delaying or cancelling planned flights, increased regulation or other systemic consequences. Our inability to meet our safety standards or adverse publicity affecting our reputation as a result of accidents, mechanical or operational failures, or other safety incidents could have a material adverse effect on our business, financial condition and results of operation. In addition, our aircraft may be grounded by regulatory authorities due to safety concerns that could have a material adverse effect on our business, financial condition, results of operations and prospects.

Crashes, accidents or incidents of aircraft involving us or our competitors could have a material adverse effect on our business, financial condition and results of operations.

The operation of aircraft is subject to various risks, and we expect demand for our air mobility services to be impacted by accidents or other safety issues regardless of whether such accidents or issues involve our aircraft.

Crashes, accidents or incidents involving our aircraft, or involving aircraft operating our powertrains, once developed, are possible. Any such occurrence would negatively impact our business, financial condition and results of operations in a number of ways. An accident or incident involving an aircraft operated by us or by a third-party operator on our behalf or using our powertrains, could result in significant potential claims of injured passengers and others, as well as repair or replacement of a damaged aircraft and its consequential temporary or permanent loss from service. For example, in January 2024, a Southern flight was forced to make an emergency landing following take-off in severe weather from Dulles International Airport in Virginia. Substantial claims resulting from an accident in excess of our related insurance coverage would harm our operational and financial results. Moreover, any aircraft accident or incident, even if fully insured or due to reasons not attributable to us or our operations or products, could result in negative public perception that our operations are less safe or reliable than other providers and have a material adverse effect on our reputation, business and results of operations. Safety issues experienced by a particular model of aircraft could impact consumer confidence in that particular aircraft type or the air transportation services industry as a whole, or result in a regulatory body grounding that particular aircraft model. If we or other operators experience accidents with aircraft models that we operate, obligating us to take such aircraft out of service until the cause of such accidents is determined and rectified, we might lose revenues and might lose customers. The value of the aircraft model might also be permanently reduced in the secondary market if the model were to be considered less desirable for future service.

Moreover, such accidents or incidents could also have a material impact on our ability to obtain or maintain FAA certification for our aircraft in a timely manner, or at all.

If our personnel, third-party contractors with whom we have arrangements, our aircraft, other types of aircraft or other companies in the industry are involved in a public incident, accident, catastrophe or regulatory enforcement action, we could be exposed to significant reputational harm and/or 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.

32

Further, as we develop and manufacture fully-electric and hybrid-electric powertrains and as these powertrains are implemented in aircraft that we sell to other operators, we may be exposed to additional risks and demand for our newly developed products will be negatively impacted by accidents or incidents involving the powertrains, including during test flights of prototypes. Such events could impact confidence in not just our products, but the development of electrification technology as a whole. This could have a material adverse effect on our future growth, financial condition and results of operations.

Risks Related to Our Dependence on Third Parties

We are substantially dependent upon our relationships with our strategic partners, and we are or may be subject to risks associated with such strategic alliances. Our reliance on these arrangements, and the loss of any such alliances or arrangements or failure to identify future opportunities could affect our growth plans.

We intend to collaborate with leading aerospace OEMs and industry leading engineering-for-hire firms to develop a set of fully-electric and hybrid-electric powertrains. We have entered into agreements with TAI for, among other things, the purchase of 90 new Cessna Caravans, with an option for up to 25 additional Cessna Caravans, as well as the provision of certain services, in anticipation of the development of fully-electric and hybrid-electric powertrains. We have also entered into an agreement with AeroTEC to develop, and to apply for STCs from the FAA for, fully-electric and hybrid-electric variants of the Cessna Caravan, as well as the development and supply of aircraft electric propulsion units (“EPUs”) for fully-electric and hybrid-electric powertrains, to be initially designed for the Cessna Caravan.

Some of our current arrangements are contingent upon certain conditions or the entry into definitive documentation in the future. Our agreements with TAI are subject to certain milestones that, if we do not meet, may result in TAI’s option to terminate the agreements. See the section titled “Licensing, Exclusivity and Aircraft Purchase Arrangements - Textron Agreement” in Note 15, Commitments and Contingencies in the accompanying consolidated financial statements for further details on our agreements with TAI .

We have entered into a joint venture agreement with Palantir for the development of SurfOS. The joint venture introduces significant risks for us, including technology dependence on Palantir's proprietary software platforms, potential misalignment and relationship challenges with Palantir, and uncertainties in securing adequate funding, all of which could adversely impact the Company's business operations and financial stability.

Such strategic business relationships will be a critical component in the growth and success of our business and, in particular, our ability to develop and commercialize fully-electric and hybrid-electric powertrains and related aircraft. However, there are no assurances that we will be able to timely meet all of the conditions of these agreements, if at all, maintain these relationships or continue to identify or secure suitable business relationship opportunities in the future, or that our competitors will not 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 any conflicts arise between our strategic partners and us, the other party may act in a manner adverse to us and could limit our ability to implement our business strategies, which could impact our projected production timelines and number of powertrains produced or aircraft modified. Our strategic partners may also develop, either alone or with others, products in related fields that are competitive with our products. Specifically, conflicts with our key strategic partners, including TAI and AeroTEC, could adversely impact our ability to develop and manufacture our planned powertrain and our planned subsequent modification of aircraft, which, in turn could have a material adverse effect on our prospects, business, financial condition and results of operation.

If we are unable to successfully maintain, source and execute on strategic relationship opportunities in the future related to electrification or other technologies relevant to our competitive position, or if any of our agreements with our strategic partners were to be terminated, our overall growth could be impaired, and there could be a material adverse effect on our business, financial condition and results of operations.

Our success will depend on our ability to economically outsource the production, assembly and installation of our fully-electric and hybrid-electric powertrain solutions at scale, and our suppliers for the parts and components of these powertrains are an important part of our business model.

We plan to outsource the majority of the production, assembly and installation of our fully-electric and hybrid-electric powertrain solutions. As such, our suppliers, including single source suppliers for certain components, are a key

33

part of our business model in order to manufacture our planned fully-electric and hybrid-electric powertrains for the Cessna Caravan. We have strategically partnered with companies that we believe to be industry leaders in order to supply the highest quality components for, and to help us develop, our fully-electric and hybrid-electric powertrains. Many of the components for our planned fully-electric and hybrid-electric powertrains will be custom made for us, which may expose us to additional risks if one or more components become unavailable. This supply chain exposes us to multiple potential sources of delivery failure or component shortages for our future powertrain, most of which are out of our control, including shortages of, or disruptions in the supply of, the raw materials used by our suppliers in the manufacturing of components, disruptions to our suppliers’ workforce (such as strikes or labor shortfalls) and disruptions to, or capacity constraints affecting, shipping and logistics.

Moreover, we anticipate that a significant concentration of the production, assembly and installation of certain components will be performed by a small number of outsourcing partners. While these arrangements can lower operating costs, they also reduce our direct control over production and distribution. Such diminished control may have an adverse effect on the quality or quantity of products or services, or our flexibility to respond to changing conditions. We expect to rely on single-source suppliers to supply and produce many components. Any failure of these suppliers or outsourcing partners to perform could require us to seek alternative suppliers or to expand our production capabilities, which could incur additional costs and have a negative impact on our cost or supply of components or finished goods.
