Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis reflects the historical results of operations and financial position of Surf Air Mobility Inc., and its consolidated subsidiaries. Prior to the Internal Reorganization (as defined below) on July 21, 2023, these results comprised the operations of Surf Air Global Limited, the predecessor to Surf Air Mobility Inc. References in this section to the “Company”, “we” or “our” refer to Surf Air Mobility Inc. and its consolidated subsidiaries, including Southern Airways Corporation. Unless otherwise indicated, all dollar amounts are set forth in thousands, except share and per share data.

The following discussion and analysis is intended to help the reader understand the Company’s results of operations and financial condition. This discussion and analysis is provided as a supplement to, and should be read in conjunction with, the information included in Item 8 Financial Statements and Supplementary Data in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to the Company’s plans and strategy for its business, includes forward-looking statements that involve risks and uncertainties. The Company’s actual results and outcomes, and the timing of its results and outcomes, may differ materially from management’s expectations as a result of various factors, including but not limited to those discussed in the sections entitled “Risk Factors” and “Special Note Regarding Forward-Looking Statements” included within this Annual Report on Form 10-K.

Overview of the Business

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, with the 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 drive an innovative platform developing a proprietary, AI-enhanced aviation software operating system as well as 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 New York Stock Exchange (“NYSE”). For 2024, the Company’s combined network 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 platform.

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.

Internal Reorganization

On July 21, 2023, SAGL Merger Sub Inc., a wholly-owned subsidiary of the Company, was merged with and into Surf Air, after which Surf Air became a wholly-owned subsidiary of the Company (the “Internal Reorganization”).

Pursuant to the Internal Reorganization, all ordinary shares of Surf Air outstanding as of immediately prior to the closing, were canceled in exchange for the right to receive shares of the Company’s common stock and all rights to receive ordinary shares of Surf Air (after giving effect to the conversions) were exchanged for shares of the Company’s common stock (or warrants, options or RSUs to acquire the Company’s common stock, as applicable) at a ratio of 22.4 Surf Air shares to 1 share of the Company’s common stock. Such conversions, as they relate to the ordinary shares of Surf Air, and all rights to receive ordinary shares, have been reflected as of all periods presented herein.

On July 27, 2023, the Company’s common stock was listed for trading on the NYSE.

As the Internal Reorganization took place on July 21, 2023, the financial statements presented herein reflect the financial position, results of operations and cash flows of Surf Air, the predecessor to the Company, for all periods prior to July 21, 2023. Following the Internal Reorganization, the financial position, results of operations and cash flows are those of the Company.

Reverse Stock Split

On August 16, 2024, the Company effected a seven-for-one reverse stock split for all shares of the Company’s common stock issued and outstanding. As a result of the reverse stock split, every seven shares of the Company’s old common stock were converted into one share of the Company’s new common stock. Fractional shares resulting from the reverse stock split were settled by cash payment.

Options, and other like awards, to purchase the Company’s common stock were also adjusted in accordance with their terms to reflect the reverse stock split.

Adjustments resulting from the reverse stock split have been retroactively reflected as of all periods presented herein.

Southern Acquisition

On July 27, 2023 (the “Acquisition Date”), immediately prior to the Company’s listing on the NYSE and after the consummation of the Internal Reorganization, the Company effected the acquisition of all equity interests of Southern Airways Corporation (“Southern”), whereby a wholly-owned subsidiary of the Company merged with and into Southern, after which Southern became a wholly-owned subsidiary of the Company (the “Southern Acquisition”). Pursuant to the agreement to acquire Southern, Southern stockholders were to receive 2,321,428 shares of the Company's common stock, which was based on the aggregate merger consideration of $81.25 million at the $35.00 per share opening price on the first day of trading of the Company's common stock. In total, 2,321,423 shares of Company common stock were issued to former Southern shareholders while the remaining amount was paid out in cash in lieu of fractional shares to those shareholders on a pro rata basis.

Southern is a scheduled service commuter airline serving cities across the United States that is headquartered in Palm Beach, Florida and commenced flight operations in June 2013. It is a certified Part 135 operator that operates a fleet of over 50 aircraft, including the Cessna Caravan, the Cessna Grand Caravan, the Pilatus PC-12, and the Tecnam Traveller. Southern provides both seasonal and full-year scheduled passenger air transportation service in the Mid-Atlantic and Gulf regions, Rockies and West Coast, and Hawaii, with select routes subsidized by the United States Department of Transportation (“U.S. DOT”) under the Essential Air Service (“EAS”) program.

Following the Southern Acquisition, the Company operates a combined regional airline network servicing U.S. cities across the Mid-Atlantic, Gulf South, Midwest, Rocky Mountains, West Coast, New England and Hawaii.

The results of operations of Southern are included in the Company’s consolidated financial statements from the date of acquisition, July 27, 2023, through December 31, 2024. For historical financial information of Southern prior to the Acquisition Date, refer to the sections entitled “Unaudited Condensed Consolidated Financial Statements for Southern Airways Corporation” and “Audited Financial Statements for Southern Airways Corporation as of December 31, 2022 and 2021 and for the Years Ended December 31, 2022 and 2021” in the Form 8-K/A filed August 29, 2023.

2024 Operating Environment

Since 2020, the Company has been incurring expenses to support the development of the technology of its digital platform with the aim of enabling the regional air mobility market to operate at scale and to enhance the user’s ability to make informed decisions based on multiple first and third party data sources as well as connected aircraft, and the Company expects these development expenses to continue to be incurred. Additionally, the Company is developing fully-electric and hybrid-electric powertrain technologies with its commercial partners to electrify existing fleets and new aircraft. As a result, the Company expects to incur significant costs in the future to support the development of this technology.

In addition to incremental costs incurred in the execution of the Company’s near and long-term business strategy, the Company has experienced inflationary pressures, which have materially increased the Company’s costs for aircraft fuel, wages and benefits and other goods and services critical to its operations during 2023 and 2024 and believes perceived recessionary risks have impacted the 2024 results. For example, perceived recessionary risks may cause companies and individuals to reduce travel for either professional or personal reasons, and drive higher prices in the supply chain the Company relies upon. In addition, the Company incurred greater than expected losses and negative cash flows from operating activities during 2024 due to inefficient aircraft utilization, primarily caused by an underutilization of pilots and a shortage of maintenance personnel and critical aircraft components, which, in aggregate, have challenged the Company’s ability to serve its customers as desired and, in turn, cover expenses, specifically related to its scheduled service offerings.

As such, the extent to which global events and market inflationary impacts will affect our financial condition, liquidity and future results of operations is uncertain. Given the uncertainty regarding the length, and intensity, of these factors, the Company cannot reasonably estimate their impact on its future results of operations, cash flows or financial condition. The Company continues to actively

monitor its financial condition, liquidity, operations, suppliers, industry and workforce. As the Company does not currently, and does not intend in the foreseeable future to, enter into any transactions to hedge fuel costs, or otherwise fix labor costs, the Company will continue to be fully exposed to fluctuations in prices of material operating costs.

During January 2025, the Company utilized an abundance of caution and voluntarily cancelled a significant number of scheduled flights due to maintenance concerns. The Company took actions to mitigate these concerns and returned its operations to full schedule during the first quarter of 2025. The most significant financial impacts of these cancellations have been lost revenues, lost operating income, decreased operating cash flows, and unplanned maintenance costs.

Key Operating Measures

In addition to the data presented in our consolidated financial statements, we use the following key operating measures commonly used throughout the air transport industry to evaluate our business, measure our performance, develop financial forecasts and make strategic decisions. The following table summarizes key operating measures for each period presented below, which are unaudited.

Year Ended December 31, Change

Results of Operations

Results of the Company’s Operations for the Years Ended December 31, 2024 and 2023

The following table sets forth our consolidated statements of operations data for the years ended December 31, 2024 and 2023 (in thousands, except percentages):

Year Ended December 31, Change

Operating expenses:

Other income (expense):

Revenue

Revenue increased by $58.9 million, 97%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The increase in revenue was attributable to the following changes in on-demand and scheduled revenues (in thousands, except percentages):

Year Ended December 31, Change

Scheduled revenue increased by $51.3 million, or 130%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. Absent the impact of the Southern Acquisition, the total scheduled revenue decreased by $0.6 million, or -17%, which was primarily attributable to a decline in our membership subscription base.

The impact of the Southern Acquisition contributed an increase of $52 million, or 146%, to scheduled revenue primarily related to EAS revenue of $30.3 million, passenger revenue of $20.2 million, and other revenue of $1.5 million, due to the results of Southern only being included for the period from July 27 to December 31, 2023 for purposes of the Company’s 2023 financial results.

On-demand revenue increased by $7.6 million, or 36%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. Of the total 3,515 on-demand charter flights, absent the impact of the Southern Acquisition, the Company conducted 2,478 on-demand charter flights during the year ended December 31, 2024 compared to 2,282 on-demand charter flights during the year ended December 31, 2023.

The increase in on-demand charter flights, absent the impact of the acquisition of Southern, was driven by increases in marketing efforts for our on-demand products and other service offerings, and was the primary driver accounting for roughly $5.5 million of the total on-demand revenue increase period over period.

The impact of the Southern Acquisition was to contribute an increase of $1.6 million to on-demand revenue during the year ended December 31, 2024 for trips in the Hawaii-based operations focusing on providing route services for construction crews, school events and leisure travel.

Operating Expenses

Cost of Revenue, exclusive of depreciation and amortization

Cost of revenue increased by $48 million, or 78%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. Of the total 3,515 on-demand charter flights, absent the impact of the acquisition of Southern, the Company conducted 2,478 on-demand charter flights in the year ended December 31, 2024 an increase from 2,282 for the year ended December 31, 2023, which resulted in a $5.8 million increase in cost of revenue associated with Company on-demand charter flights.

The Southern Acquisition contributed to an increase in cost of revenue of $43.9 million, or 129%, during the year ended December 31, 2024 primarily due to aircraft expenses of $25.2 million, pilot expenses of $10.9 million, customer care expenses of $5.4 million, station expenses of $1.9 million, reservation systems of $0.9 million, and passenger re-accommodation expenses of $0.5 million.

Technology and Development

Technology and development expenses increased by $3.2 million, or 15%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The increase was driven primarily by an increase in expenses related to software development work with Palantir of $4.1 million. These increases were partially offset by a decrease in labor and labor related expenses for the technology team of $0.9 million due to a decrease in headcount.

Sales and Marketing

Sales and marketing expenses decreased by $2.5 million, or -25%, for the year ended December 31, 2024, compared to the year ended December 31, 2023, primarily due to a decrease in brand awareness and strategic digital marketing expenses of $0.5 million and a $2.0 million decrease in management incentive plan expenses.

General and Administrative

General and administrative expenses decreased by $70.8 million, or -70%, for the year ended December 31, 2024, compared to the year ended December 31, 2023. The primary drivers of the decrease in general and administrative expenses were a decrease in stock-based compensation expense of $54.3 million and decreases in transaction related costs associated with the Company’s public listing, of $22.0 million. These decreases were partially offset by an increase in professional fees not associated with the Company’s public listing of $3.5 million due to a higher volume of corporate transactions during the year ended December 31, 2024.

Depreciation and Amortization

Depreciation and amortization expenses increased by $4.6 million, or 122%, for the year ended December 31, 2024, compared to the year ended December 31, 2023 primarily due to depreciation of engines and aircraft, as well as amortization of intangibles acquired in the Southern Acquisition for the full twelve months during year ended December 31, 2024.

Impairment of Goodwill

The Company recorded impairment charges to previously recorded goodwill of its Southern business unit of $60.0 million during the year ended December 31, 2023 as a result of the identification of impairment indicators during the fourth quarter of 2023. No such charges were recorded during the year ended December 31, 2024.

Other Income/(Expense)

Other expense, net decreased by $42.3 million, or -74%, for the year ended December 31, 2024 compared to the year ended December 31, 2023. There are two primary drivers for the decrease in other expense:

•

$38.5 million decrease in changes in fair value of financial instruments due to valuation adjustments recorded during the first half of 2023, and upon settlement of convertible notes and SAFEs as part of the Company’s direct listing;

•

$3.7 million decrease in other expense, primarily due to a stock-based expense of $3.2 million to Tuscan Holdings in full satisfaction of the termination of a business combination agreement during the year ended December 31, 2024.

Net Loss

The total decrease in net loss of $175.8 million for the year ended December 31, 2024 compared to the year ended December 31, 2023 is primarily due to a reduction of expenses as described above, including reductions in goodwill impairment of $60.0 million, decreases in general and administrative expenses of $70.8 million, and decreases in other expenses of $42.3 million.

Cash Flow Analysis

The following table presents a summary of our cash flows (in thousands):

Year Ended December 31,

Net cash provided by (used in):

Net change in cash and cash equivalents $ 19,244 $ 1,519

Cash Flow from Operating Activities

For the year ended December 31, 2024, net cash used in operating activities was $54.3 million, driven by a net loss of $74.9 million, net reversals of $6.0 million in non-cash stock-based compensation, and a $4.3 million reduction in deferred revenue. These operating outflows were partially offset by changes in fair value of financial instruments of $11.7 million, increases in accrued expenses and other current liabilities of $8.4 million, and depreciation and amortization expenses of $8.3 million.

For the year ended December 31, 2023, net cash used in operating activities was $64.4 million, driven by a net loss of $250.7 million and a $2.1 million reduction in operating lease liabilities. These operating outflows were partially offset by non-cash changes in fair value of financial instruments of $50.2 million, non-cash impairment of goodwill of $60.0 million, non-cash stock-based compensation expenses of $48.3 million, increases in accounts payable and other liabilities of $28.6 million, increases in depreciation and amortization of $1.1 million, and increases in prepaid expenses and other current assets of $0.7 million.

In 2023, the Southern Acquisition resulted in net cash outflows from operating activities of $3.9 million. This was primarily driven by a $3.3 million reduction in deferred income taxes and a net loss of $4.6 million. These were mostly offset by increases in depreciation and amortization of $2.7 million, and non-cash operating leases of $1.5 million.

Net cash used in operating activities decreased period over period by $10.1 million, driven by a $175.8 million decrease in net loss. This was largely offset by a decrease of $38.5 million in non-cash changes in fair value of financial instruments, a decrease of $60.0 million in impairment of goodwill charges, decreases of $54.2 million in non-cash stock-based compensation expenses, and a decrease of $10.5 million in changes in accrued expenses and other liabilities.

Cash Flow from Investing Activities

For the year ended December 31, 2024, net cash used in investing activities was $3.6 million, a decrease of $3.5 million compared to the year ended December 31, 2023, driven by an increase of $10.5 million in cash from sales of fixed assets and partially offset by an increase in fixed asset purchases of $4.2 million and $2.2 million in internal use software development costs. Totals for 2023 include $0.7 million in net cash received from the Southern Acquisition.

Cash Flow from Financing Activities

For the year ended December 31, 2024, net cash provided by financing activities was $77.2 million due to proceeds from borrowings under long term debt agreements, net of repayments, of $36.2 million, borrowings from related parties of $34.5 million, net proceeds of $2.8 million from collateralized borrowings, and proceeds from the GEM share purchase agreement of $3.9 million.

For the year ended December 31, 2023, net cash provided by financing activities was $73.0 million from proceeds from the issuance of preferred shares, common stock, and exercise of share options of $30.2 million, proceeds from borrowings of SAFE and convertible notes of $11.7 million, proceeds from borrowings due to related parties of $22.4 million, and proceeds from the GEM share purchase agreement of $10.2 million. These factors were offset by $1.5 million due to payments on long-term debt and amounts due under finance leases acquired from Southern.

Net cash provided by financing activities increased period over period by $4.2 million, primarily driven by increases in net borrowings of long term debt of $37.5 million and a $12.0 million increase in borrowings from related parties. These increases were partially offset by reductions in proceeds from the GEM Purchase of $25.0 million, reductions in proceeds from the Share Purchase Agreement of $6.3 million, an $8.0 million reduction in borrowings under convertible note agreements, and a $3.7 million reduction in proceeds from SAFE instruments and the sale of convertible preferred shares.

Liquidity and Capital Resources

The Company has incurred losses from operations, negative cash flows from operating activities and has a working capital deficit. In addition, the Company is currently in default of certain excise and property taxes as well as certain debt obligations. These tax and debt obligations are classified as current liabilities on the Company’s Consolidated Balance Sheets as of December 31, 2024 and December 31, 2023. As discussed in Note 15, Commitments and Contingencies, on May 15, 2018, the Company received a notice of a tax lien filing from the Internal Revenue Service (“IRS”) for unpaid federal excise taxes for the quarterly periods from October 2016 through September 2017 in the amount of $1.9 million, including penalties and interest as of the date of the notice. The Company agreed to a payment plan (the “Installment Plan”) whereby the IRS would take no further action and remove such liens at the time such amounts have been paid. In 2019, the Company defaulted on the Installment Plan. Defaulting on the Installment Plan can result in the IRS nullifying such plan, placing the Company in default and taking collection action against the Company for any unpaid balance. The Company is currently in default of these obligations, with a total outstanding federal excise tax liability, including accrued penalties and interest, of $7.7 million included in accrued expenses and other current liabilities on the Consolidated Balance Sheet as of December 31, 2024. The Company has also defaulted on its property tax obligations in various California counties in relation to fixed assets, plane usage and aircraft leases. The Company’s total outstanding property tax liability including penalties and interest is approximately $1.6 million as of December 31, 2024. Additionally, Los Angeles County has imposed a tax lien on four of the Company’s aircraft due to the late filing of the Company’s 2022 property tax return. As of December 31, 2024, the amount of property tax, interest and penalties related to the Los Angeles County tax lien for all unpaid tax years was approximately $1.1 million. The Company is in the process of remediating the late filing and payment of the property taxes due to Los Angeles County. As of December 31, 2024, the Company was also in default of the Simple Agreements for Future Equity with Token allocation (“SAFE-T”) note, where the note matured in July 2019 (see Note 11, Financing Arrangements). The SAFE-T note is subordinate to the Company’s Convertible Note Purchase Agreement (see Note 11, Financing Arrangements); therefore, the Company cannot pay the outstanding balance prior to paying amounts due under the Convertible Note Purchase Agreement. The SAFE-T note had an outstanding principal amount of $0.5 million as of December 31, 2024 and December 31, 2023.

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

The airline industry and the Company’s operations are cyclical and highly competitive. The Company’s success is largely dependent on the ability to raise debt and equity capital, achieve a high level of aircraft and crew utilization, increase flight services and the number of passengers flown, and continue to expand into regions profitably throughout the United States.

The Company’s 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 the Company’s 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 its 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, (v)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 the business model.

The Company has historically funded its operations and capital needs primarily through the net proceeds received from the issuance of various debt instruments, convertible securities, related party funding, and preferred and common share financing arrangements. During the year ended December 31, 2023, the Company received $8 million under a convertible note purchase agreement with Partners for Growth V, L.P. (“PFG”), $25.0 million through the Share Purchase Agreement with GEM Global Yield LLC SCS (“GEM”) and $10.2 million in advances and draws under the second amended and restated Share Purchase Agreement with GEM (see Note 12, Share Purchase Agreement, GEM Purchase, and Mandatory Convertible Security). During the year ended December 31, 2024, the Company received an additional $2.5 million in advances under the second amended and restated Share Purchase Agreement with GEM. The Company had previously filed a Form S-1 registration statement (File No. 333-275434) with the SEC, registering up to 42,857,143 shares of the Company’s common stock, which represents the balance of the full amount of shares of common stock that the Company estimated could be issued and sold to GEM for advances under the Share Purchase Agreement, plus the amount of shares the Company estimated could be sold to GEM for $50.0 million under the Share Purchase Agreement, (the “Prior Registration Statement”). In connection with the GEM Mandatory Convertible Security (see Note 12, Share Purchase Agreement, GEM Purchase, and Mandatory Convertible Security), the Company deregistered all of the shares registered but unsold under the Prior Registration Statement on June 4, 2024. The combined 46,428,571 shares contemplated under the Prior Registration Statement have been included in a Form S-1 Registration Statement (File No. 333-279929), which was declared effective by the SEC on August 7, 2024. As of December 31, 2024, the contractual terms allow the Company to make further advances of up to $97.5 million under the Share Purchase Agreement. Additionally, the Company has the ability to draw an additional $298.6 million under the Share Purchase Agreement, subject to daily volume limitations and GEM’s requirement to hold less than 10% of the fully-diluted shares of the Company. As of December 31, 2024, GEM held 0% of the then fully-diluted shares of the Company. At December 31, 2024, the daily volume limitations under the Share Purchase Agreement significantly restricted our ability to take additional draws under the Share Purchase Agreement to approximately 293 thousand shares per draw. Additionally, the Company’s ability to draw upon the Share Purchase Agreement is contingent on the Company’s common stock being listed on a national exchange. The Company is currently attempting to resolve one listing requirement violation with the New York Stock Exchange. While not currently subject to de-listing, the Company’s inability to cure this listing requirement violation would impact its ability to raise capital through the Share Purchase Agreement.

Additionally, during the year ended December 31, 2024, the Company entered into a credit agreement with certain affiliates of Comvest Partners, as lenders, pursuant to which the Company borrowed $44.5 million under a four-year term loan, and $5.5 million of delayed draw commitments.

The Company is currently implementing operational improvements and stringent operating expenses management to improve the profitability of its airline operations. In parallel, the Company is advancing its technology initiatives, including its software technology platform and Caravan electrification programs. In addition, the Company continues 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 or entering into other financing arrangements, forming joint venture and other partnerships, and restructuring of operations to grow revenues and decrease expenses. There can be no assurance that the Company will be successful in achieving its strategic plans, or that new financing will be available to the Company in a timely manner or on acceptable terms, if at all. If the Company is unable to raise sufficient financing when needed or events or circumstances occur such that the Company does not meet its strategic plans or, the Company will be required to take additional measures to conserve liquidity, which could include, but not necessarily limited to, reducing certain spending, altering or scaling back development plans, including plans to equip regional airline operations with fully-electric or hybrid-electric aircraft, or reducing funding of capital expenditures, which could have a material adverse effect on the Company’s financial position, results of operations, cash flows, and ability to achieve its intended business objectives. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments

to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

The Company’s capital expenditures in 2024 and in 2023 were limited to payments made for aircraft purchases under the TAI Aircraft Supply Agreement, aircraft supply deposits, aircraft parts, engines, immaterial purchases and internally developed software. The Company intends to invest significantly in expansion of its network footprint and in development of electrified powertrain technology and its commercial platform. Expansion of the network will require acquisition of aircraft over the next five years with an expected cost of approximately $0.3 billion. The Company has an order in place with TAI for 90 Cessna Grand Caravan aircraft with an option for an additional 26 Cessna Grand Caravan aircraft, with expected delivery taken over the next five years. The Company took delivery of four aircraft under this agreement during 2024. As of December 31, 2024, the Company had made deposits of $2.0 million for aircraft that are scheduled to be delivered in 2026. The Company may finance these aircraft through Jetstream Aviation Capital, with which the Company currently has a sale-leaseback financing arrangement of up to $450 million, and additional debt facilities that it intends to obtain. See the section entitled “Risk Factors — Risks Related to Our Financial Position and Capital Requirements — Our past financial results may not be a reliable indicator of our future results.” The Company has engaged AeroTEC to develop fully-electric and hybrid-electric Supplemental Type Certificates (“STCs”) for the Cessna Grand Caravan in partnership with TAI.

Commitments

The Company has entered into various contractual arrangements related to the build-out of the Company’s air service fleet, the development of its proprietary hybrid and electric aircraft technology, and the build out of its aircraft as a service platform. These arrangements include commitments for payments pursuant to licensing agreements, which routinely contain provisions for guarantees or minimum expenditures during the terms of the contracts. The Company also enters into long-term debt arrangements that include periodic interest and principal payments. Additionally, the Company routinely enters into noncancelable lease agreements for aircraft and operating locations, which contain minimum rental payments.

The following table summarizes the Company’s contractual commitments and obligations (in thousands) :

Repayment of related party term loans 50,000 — — — 50,000 — —

Repayment of convertible notes 8,034 — — — 8,034 — —

Minimum payments under data license agreements 9,500 9,500 — — — — —

Critical Accounting Policies and Estimates

The consolidated financial statements of the Company are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of income and expense during the reported period.

Our management believes that the accounting estimates listed below are those that are most critical to the portrayal of our financial condition and results of operations, and that require management’s most difficult, subjective and complex judgments in estimating the effect of inherent uncertainties.

Goodwill

We have made acquisitions in the past that included goodwill. Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill is not amortized but is subject to an annual (or under certain circumstances more frequent) impairment test in the fourth quarter based on its estimated fair value. We test more frequently if there are indicators of impairment, or whenever such circumstances suggest that the carrying value of goodwill may not be recoverable. Examples of such events and circumstances that we would consider include the following:

•

macroeconomic conditions such as deterioration in general economic conditions, limitations on accessing capital, or other developments in equity and credit markets;

•

industry and market considerations such as a deterioration in the environment in which we operate, an increased competitive environment, a decline in market-dependent multiples or metrics (considered in both absolute terms and relative to peers), a change in the market for our products or services, or a regulatory or political development;

•

cost factors such as increases in raw materials, labor, or other costs that have a negative effect on earnings and cash flows;

•

overall financial performance such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; and

•

other relevant entity-specific events such as changes in management, key personnel, strategy, or customers.

An entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the impairment test is unnecessary. Goodwill is tested at a level of reporting referred to as “the reporting unit.” Following the Southern Acquisition, we created a new reporting unit for Southern on the basis of the availability of discrete financial information and the timing of integrating the operations of Southern into our operations. All goodwill originally recorded for the Southern Acquisition was allocated to this reporting unit.

Shortly after the Southern Acquisition, the Company performed its annual goodwill impairment assessment on a qualitative basis as of October 1, 2023, and concluded that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. This conclusion was primarily based on the operations of Southern being consistent with forecasts existing as of the acquisition date and the Company’s plans to re-fleet and expand Southern’s operations. Subsequent to this analysis, the Company identified indicators of impairment of the Southern reporting unit as of December 31, 2023. This was based on operational challenges that were expected to be remediated in the fourth quarter, such as: additional delays of aircraft maintenance due to the unavailability of parts, which resulted in a higher cancellation rate of scheduled flights. These delays were expected to, and did, continue into 2024. Additionally, we incurred higher cash requirements than expected to fund the operations of the Southern reporting unit during the fourth quarter of 2023, primarily due to higher maintenance costs. Further, unplanned delays in aircraft deliveries under the Textron aircraft supply agreement, including December 2023 cancellations of both firm deliveries and additional purchase options, have delayed re-fleeting efforts. Indicators of impairment also include a decline in the market price of our common stock and corresponding continued decline in our market capitalization from the date of the Southern Acquisition. As a result, we determined that it was more likely than not that the fair value of the Southern reporting unit was lower than its carrying value. As a result, the Company performed a quantitative assessment to compare the fair value of the reporting unit to its carrying amount as of December 31, 2023. The Company concluded that the carrying value of the Southern reporting unit exceeded its fair value and, as such, recorded a $60.0 million impairment of goodwill in its Southern reporting unit during the fourth quarter of 2023.

As of December 31, 2024, we had no remaining goodwill balance. The fair value of goodwill in the impairment test was determined using a combination of an income approach, which estimates fair value based upon projections of future revenues, expenses, and cash flows discounted to their respective present values, and a market approach. The valuation methodology and underlying financial information included in our determination of fair value required significant judgments by management. The principal assumptions used in our discounted cash flow analysis consisted of (a) long-term projections of financial performance, inclusive of scheduled completion factors and prospective operating cost assumptions and (b) the weighted-average cost of capital of market participants, adjusted for the risk attributable to us and the industry in which we operate. Under the market approach, the principal assumption included an estimate of a control premium.

Stock-Based Compensation

We grant stock options, warrants, restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”) to certain employees, as well as non-employees (including directors and others who provide services to us) under our stock plans. We recognize compensation expense resulting from stock-based payments over the period for which the requisite services are provided.

Stock Options and Warrants

We use the Black-Scholes option pricing model to estimate the fair value of the stock options and warrants at the measurement date. The grant date is deemed to be the appropriate measurement date for stock options issued to employees and non-employees. We have elected to account for forfeitures as they occur.

The use of the Black-Scholes option pricing model requires the use of subjective assumptions, including the following:

•

Fair Value of Common Stock—Prior to the Company’s direct listing, the absence of an active market for our common stock required us to estimate the fair value of our common stock. See the subsection titled “common stock Valuations” below. For valuations completed subsequent to the direct listing, the fair value of each share of underlying common stock is based on the closing price of our common stock as reported on the date immediately preceding the date of grant.

•

Risk-Free Interest Rate—The yield on actively traded non-inflation indexed U.S. Treasury notes with the same maturity as the expected term of the underlying options was used as the average risk-free interest rate.

•

Expected Term—The expected term of options granted to employees was determined based on management’s expectations of the options granted, which are expected to remain outstanding. Where appropriate, we calculated the expected term using the simplified method for “plain vanilla” stock option awards.

•

Expected Volatility—Given our limited trading history subsequent to the direct listing, there is limited substantive share price history to calculate volatility and, as such, we have elected to use an approximation based on the volatility of other comparable public companies, which compete directly with us, over the expected term of the options.

•

Dividend Yield—We have not issued regular dividends on common shares in the past nor do we expect to issue dividends in the future. As such, the dividend yield has been estimated to be zero.

We will continue to use judgment in evaluating the expected volatility and expected terms utilized in our stock-based compensation expense calculations on a prospective basis. As we continue to accumulate additional data related to our common stock, we may refine our estimates, which could materially impact our future stock-based compensation expense. Additionally, had we arrived at different assumptions of stock price volatility or expected lives of our stock options, our stock-based compensation expense and results of operations may be materially different.

Restricted Stock Units

The fair value of RSUs is estimated based on the fair value of our common stock on the grant date. Estimating the grant date fair value of the common stock underlying RSU grants prior to our direct listing was highly judgmental due to the lack of an observable market for our common stock. Prior to our direct listing, the fair value of the Company’s common stock was determined by considering a number of objective and subjective factors including: contemporaneous third-party valuations of our common stock, sales of our redeemable convertible preferred stock to outside investors in arms-length transactions, the Company’s operating and financial performance, the lack of marketability, and the general and industry-specific economic outlook, amongst other factors. Estimating the grant date fair value of the RSUs, including the PSUs discussed below, was highly sensitive due to the volume of RSUs granted and increasing fair value of our common stock as we approached our direct listing. For RSUs granted prior to the Company’s direct listing, all awards were deemed to have vested upon the satisfaction of both a service-based vesting condition and a liquidity event-related performance vesting condition tied to the direct listing.

Subsequent to our direct listing, the fair value of our RSUs is based on the stock price on the day immediately preceding the date of grant, there will no longer be a significant level of judgment involved that could impact the fair value of the RSUs or expense incurred.

Performance-Based Restricted Stock Units

In July 2023, we granted PRSUs to each of our three founders (“Founder PRSUs”). In October 2023, we granted 28,571 additional PRSUs as part of a hiring grant to an executive under the 2023 Plan. These and the Founder PRSUs will vest upon the satisfaction of a service condition and the achievement of certain stock price goals. We estimate the grant date fair value of PRSUs using a model based on multiple stock price paths developed through the use of a Monte Carlo simulation that incorporates into the valuation the possibility that the stock price goals may not be satisfied. A Monte Carlo simulation model requires the use of various assumptions, including the

underlying stock price, volatility, expiration term, and the risk-free interest rate as of the valuation date, corresponding to the length of time remaining in the performance period, and expected dividend yield. The derived service period calculation also requires the cost of equity assumption to be used in the Monte Carlo simulation model. Term and volatility are typically the primary drivers of this valuation. The average grant date fair value of the Founder PRSUs were estimated to be $15.82 per share, and we will recognize total stock-based compensation expense of approximately $6.3 million over the derived service period. The weighted-average grant date fair value of the PRSUs granted in October was $5.67 per share for the 7,143 RSUs vesting upon an Average Closing Price equaling or exceeding $35 per share, $3.85 per share for the 10,714 RSUs vesting upon an Average Closing Price equaling or exceeding $70 per share, and $2.73 per share for the 10,714 RSUs vesting upon an Average Closing Price equaling or exceeding $105 per share. We will recognize total stock-based compensation expense of $0.1 million over the derived service period. If the stock price goals are met sooner than the derived service period, we will adjust our stock-based compensation expense to reflect the cumulative expense associated with the vested award. Provided that each founder/ employee individually stays employed with the Company, we will recognize stock-based compensation expense over the requisite service period, regardless of whether the stock price goals are achieved. Had we arrived at different assumptions of underlying stock price or volatility our stock-based compensation expense and results of operations may be materially different.

Common Stock Valuations

Prior to our direct listing, given the absence of a public trading market for our common stock, and in accordance with the American Institute of Certified Public Accountants Accounting and Valuation Guide, Valuation of Privately-Held Company Equity Securities Issued as Compensation (the “Practice Aid”), our board of directors exercised its reasonable judgment and considered numerous objective and subjective factors to determine the best estimate of fair value of our common stock, including:

•

independent third-party valuations of our common stock;

•

the prices at which we sold shares of our preferred stock;

•

the rights, preferences and privileges of our preferred stock relative to those of our common stock;

•

our capital resources and financial condition;

•

the likelihood and timing of achieving a liquidity event, such as an initial public offering or sale of the company, given prevailing market conditions;

•

our historical operating and financial performance as well as our estimates of future financial performance;

•

valuations of comparable companies;

•

the hiring of key personnel;

•

the relative lack of marketability of our common stock;

•

industry information such as market growth and volume and macro-economic events; and

•

additional objective and subjective factors relating to our business.

The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date.

In accordance with the Practice Aid, for our historical valuations performed, we concluded the Hybrid Method was the most appropriate method for determining the fair value of our common stock given our stage of development and other relevant factors. The Hybrid Method is a scenario-based analysis that estimates value per share based on the probability-weighted present value of expected future financing events, considering each of the possible outcomes available to us, as well as the economic and control rights of each share class.

The assumptions underlying these valuations represent our board of directors’ best estimates at the time they were made, which involve inherent uncertainties and the application of the judgment of our board of directors. As a result, if factors or expected outcomes change and we use significantly different assumptions or estimates, our stock-based compensation expense could be materially different.

Subsequent to the direct listing, the fair market value of our common stock is based on its closing price as reported on the date of grant on the NYSE.

Fair Value Measurements

The Company has a significant number of debt and equity transactions that are recorded at fair value. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The assumptions used in the Company’s valuation models represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the Company’s results could reflect material fluctuation in Changes in fair value of financial instruments carried at fair value, net on the Consolidated Statement of Operations.

Fair value measurements are based on a fair value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, which are the following:

Assets and liabilities are classified in the hierarchy based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

The Company measures the fair value of certain long-lived assets including finite-lived intangible assets on a nonrecurring basis, when such assets are required to be written down to fair value if impaired. Such fair values are classified within Level 3 of the fair value hierarchy, as the valuations contain significant unobservable inputs, including assumptions of the present value of future cash flows, the use of these assets, as well as estimated disposition value.

The Company’s convertible securities and Simple Agreements for Future Equity (“SAFE”) notes are carried at fair value. SAFE notes are financial instruments whereby an investor provides an investment into the Company, and the note is subsequently converted into a preferred equity security at a discount to the price paid by other investors when and if a preferred equity is issued through a qualifying capital raise. Due to certain provisions included in the agreements for these instruments, they are classified as liabilities. Additionally, the Company elected the fair value option for certain convertible notes and SAFE notes, which requires them to be remeasured to fair value each period. If factors change and different assumptions are used, the Company’s results could reflect material fluctuation in Changes in fair value of financial instruments carried at fair value, net on the Consolidated Statements of Operations. As a result of the Internal Reorganization and settlements of SAFE notes as part of the Company’s direct listing, these balances have been significantly reduced as of December 31, 2024.

The Company has accounted for the Mandatory Convertible Security with GEM at fair value. The fair value of the liability was estimated using a model based on multiple stock price paths developed through the use of a Monte Carlo simulation that incorporates into the valuation the possibility that the Company will not be able to satisfy the liability through the issuance of shares of common stock. Significant inputs in determining period end fair values of the Mandatory Convertible Security are as follows:

•

Remaining par amount;

•

Entity specific probability of default;

•

Implied volatility

•

Applicable discount rate

•

Share price at the measurement date

Income Taxes

The determination of tax strategies and positions, along with accounting for related income taxes requires interpretation of various federal and state tax policies and assessment of the likelihood of various outcomes. Management believes that accounting for income taxes requires difficult, subjective and complex judgments and defenses. Income taxes are accounted for under the asset and liability

method in accordance with U.S. GAAP. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The likelihood of realizing the tax benefits related to a potential deferred tax asset is evaluated, and a valuation allowance is recognized to reduce that deferred tax asset if it is more likely than not that all or some portion of the deferred tax asset will not be realized.

Deferred tax assets and liabilities are calculated at the beginning and end of the period. The change in the sum of the deferred tax asset, valuation allowance and deferred tax liability during the period generally is recognized as a deferred tax expense or benefit. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date.

The Company determines whether a tax position taken or expected to be taken in a tax return is to be recognized in the consolidated financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The amount recognized is subject to estimation and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount recognized. For tax positions meeting the more likely than not threshold, the tax amount recognized in the consolidated financial statements is reduced by the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. Surf Air recognizes interest and penalties accrued related to unrecognized tax benefits, if any, in its income tax expense in the accompanying Consolidated Statement of Operations.

JOBS Act

The Company currently qualifies as an “emerging growth company” under the JOBS Act. Accordingly, the Company has elected to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 7(a)(2)(B) of the Securities Act. The Company’s utilization of these transition periods may make it difficult to compare our financial statements to those of non-emerging growth companies and other emerging growth companies that have opted out of the transition periods afforded under the JOBS Act.

ITEM 7A. QUANTITATIVE AND QUALITITATIVE DISCLOSURES ABOUT MARKET RISK

We have operations solely within the United States, and we are exposed to market risks in the ordinary course of our business. The primary risks we face are commodity price risks and macroeconomic risks.

Commodity Price Risks

We are exposed to commodity price risks. Our air mobility services require a significant amount of aircraft fuel, critical spare parts, and specialized maintenance that are affected by the price of other commodities, exchange rates, inflation, foreign demand, weather, seasonality, production, availability and other factors outside our control. We work closely with our suppliers to obtain a consistent supply of aircraft fuel and the scheduling of aircraft maintenance. Generally, we do not engage in forward purchase commitments for aircraft fuel, or for the supply of critical spare parts, outside of that held in inventory. Increases in the price of fuel, critical spare parts, and/or maintenance services could adversely affect our results if we choose for competitive or other reasons not to increase passenger ticket prices at the same rate at which operating costs increase, or if passenger ticket increases result in customer resistance. We also could experience shortages of aircraft fuel, critical spare parts, and specialized maintenance if our suppliers need to close or restrict operations due to unforeseen events.

Due to the recent pace of inflation and other global supply chain risks, including extreme weather conditions, suppliers and distributors have, and could continue to, attempt to increase prices, as well as assess certain fuel surcharges. These changes could have a negative impact on our commodity prices. For example, during 2024, as a result of global supply chain issues and extreme weather conditions, we experienced supply chain disruptions for critical spare parts and major maintenance, which resulted in higher prices and delayed delivery for those products. We continue to assess the current environment, work with our suppliers and maintenance providers and create certain contingency plans to mitigate any negative impact.

Macroeconomic Risks and the Impact of the COVID-19 Pandemic

Current macroeconomic conditions, such as inflation and increasing interest rates, increase the risk of an economic downturn. These macroeconomic conditions also negatively impact consumer discretionary spend and coupled with slower than expected increases in business and leisure travel, including as a result of many workplaces adopting remote or hybrid models, led to slowed revenue growth during 2024. Additionally, as a result of continued inflation, we have seen an increase in wage rates and costs of revenue during fiscal year 2024, which has had a negative impact on our financial results. In order to mitigate these risks, we have implemented and may in the future have to implement additional cost cutting measures, as described in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting our Business.”

Consolidated Balance Sheets as of December 31, 2024 and 2023 72

Notes to Consolidated Financial Statements 76

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Surf Air Mobility Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Surf Air Mobility Inc. and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of operations, of changes in redeemable convertible preferred shares and shareholders’ equity/(deficit) and of cash flows for the years then ended, including the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Substantial Doubt About the Company's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred losses from operations, negative cash flows from operating activities and has a working capital deficit that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Consolidated Financial Statements

Note 1. Description of Business

Organization

Surf Air Mobility Inc. (the “Company”), a Delaware corporation, 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.

Surf Air Global Limited (“Surf Air”) is a British Virgin Islands holding company and was formed on August 15, 2016. Surf Air is a technology-enabled regional air travel network, offering daily scheduled flights and on-demand charter flights. Its customers consist of regional business and leisure travelers. Headquartered in Hawthorne, California, Surf Air commenced flight operations in June 2013.

Internal Reorganization

Pursuant to the Internal Reorganization, all ordinary shares of Surf Air outstanding as of immediately prior to the closing, were canceled in exchange for the right to receive shares of the Company’s common stock and all rights to receive ordinary shares of Surf Air (after giving effect to the conversions) were exchanged for shares of the Company’s common stock (or warrants, options or restricted stock units (“RSUs”) to acquire the Company’s common stock, as applicable) at a ratio of 22.4 Surf Air shares to 1 share of the Company’s common stock. Such conversions, as they relate to the ordinary shares of Surf Air, and all rights to receive ordinary shares, have been reflected as of all periods presented herein.

On July 27, 2023, the Company’s common stock was listed for trading on the NYSE.

Reverse Stock Split

Options, and other like awards, to purchase the Company’s common stock were also adjusted in accordance with their terms to reflect the reverse stock split.

Adjustments resulting from the reverse stock split have been retroactively reflected as of all periods presented herein.

The combined 46,428,571 shares contemplated under the Prior Registration Statement have been included in a Form S-1 Registration Statement (File No. 333-279929), which was declared effective by the SEC on August 7, 2024. As of December 31, 2024, the contractual terms allow the Company to make further advances of up to $97.5 million under the Share Purchase Agreement. Additionally, the Company has the ability to draw an additional $298.6 million under the Share Purchase Agreement, subject to daily volume limitations and GEM’s requirement to hold less than 10% of the fully-diluted shares of the Company. As of December 31, 2024, GEM held 0% of the then fully-diluted shares of the Company. At December 31, 2024, the daily volume limitations under the Share Purchase Agreement significantly restricted our ability to take additional draws under the Share Purchase Agreement to approximately 293 thousand shares per draw. Additionally, the Company’s ability to draw upon the Share Purchase Agreement is contingent on the Company’s common stock being listed on a national exchange. The Company is currently attempting to resolve one listing requirement violation with the New York Stock Exchange. While not currently subject to de-listing, the Company’s inability to cure this listing requirement violation would impact its ability to raise capital through the Share Purchase Agreement.

Additionally, during the year ended December 31, 2024, the Company entered into a 4-year credit agreement with certain affiliates of Comvest Partners, as lenders, pursuant to which the Company borrowed $44.5 million under a four-year term loan, and $5.5 million of delayed draw commitments.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements of the Company are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial statements include the assets, liabilities and operating results of the Company. All intercompany balances and transactions have been eliminated in consolidation. Other than net loss, the Company does not have any other elements of comprehensive income or loss for the years ended December 31, 2024 and 2023.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of income and expense during the reporting period.

On an ongoing basis, the Company evaluates its estimates using historical experience and other factors including the current economic and regulatory environment as well as management’s judgment. Items subject to such estimates and assumptions include: revenue recognition and related allowances, valuation allowance on deferred tax assets, certain accrued liabilities, useful lives and recoverability of long-lived assets, fair value of assets acquired and liabilities assumed in acquisitions, legal contingencies, assumptions underlying convertible notes and convertible securities carried at fair value and stock-based compensation. These estimates may change as new events occur and additional information is obtained and such changes are recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates, and any such differences may be material to the Company’s consolidated financial statements.

Concentration of Risk

The financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and accounts receivable. All of the Company’s cash deposits are held at financial institutions that management believes to be of high credit quality. The Company’s cash deposit accounts may exceed federally insured limits at times. The Company has not experienced any losses on cash deposits to date. For the years ended December 31, 2024 and 2023, the US DOT accounted for 39% and 32%, respectively, of the Company's consolidated revenues.

We are dependent on part suppliers to deliver necessary airplane components in a timely manner at prices and quality levels acceptable to us. Our inability to efficiently manage these suppliers could have a material adverse effect on our business, prospects, financial condition and operating results.

Business Combination

The Company is required to use the acquisition method of accounting for business combinations. The acquisition method of accounting requires the Company to allocate the purchase consideration to the assets acquired and liabilities assumed from the acquiree based on their respective fair values as of the Acquisition Date. The excess of the fair value of purchase consideration over the fair value of these assets acquired and liabilities assumed is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing intangible assets include, but are not limited to, expected future cash flows, which includes consideration of future revenue growth and margins, and discount rates. Fair value estimates are based on the assumptions that management believes a market participant would use in pricing the asset or liability. These estimates are inherently uncertain and, therefore, actual results may differ from the estimates made. As a result,during the measurement period of up to one year from the Acquisition Date, the Company may record fair value adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired and liabilities assumed in an acquisition, whichever comes first, any subsequent adjustments are recorded in the Consolidated Statements of Operations.

Cash and Restricted Cash

Cash and restricted cash consists of cash on hand held in commercial bank accounts. The Company classifies all cash with use limited by contractual provisions as restricted cash. As of December 31, 2024 and 2023 the Company had restricted cash of $0.6 million and $0.7 million, respectively, consisting of collateral against a corporate credit card. The Company has classified the restricted cash as long term, which represents the expected lapse of the restriction.

Accounts Receivable, net

Accounts receivable primarily consist of amounts due from U.S. DOT in relation to certain air routes served by the Company under the Essential Air Service (“EAS”) program, amounts due from airline business partners, and pending transactions with credit card processors. Receivables from the U.S. DOT and our business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2024, and December 31, 2023. The Company has considered past and future financial and qualitative factors, including the age of unpaid receivables, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

Collateralized Borrowings

On August 9, 2024, the Company entered into a new revolving accounts receivable financing arrangement that will allow the Company to borrow a designated percentage of eligible accounts receivable, as defined, up to a maximum unsettled amount of $5.0 million. The agreement is secured by a first security interest in all assets of Southern Airways Express, a subsidiary of Southern. The financing arrangement is uncommitted, and upon funding does not qualify for sale accounting as the Company does not relinquish control of the receivables based on, among other things, the nature and extent of the Company’s continuing involvement.

Accordingly, the accounts receivable remain on the Company’s Consolidated Balance Sheets until paid by the customer and cash proceeds from the financing arrangement are recorded as collateralized borrowing in Accrued expenses and other current liabilities on the Consolidated Balance Sheets, with attributable interest expense recognized over the life of the related transactions. Interest expense and contractual fees associated with the collateralized borrowings are included in interest expense and other expense, net, respectively, in the accompanying Consolidated Statements of Operations.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Expenditures for major additions, equipment purchase deposits, renewals, and modifications are capitalized, while minor replacements, maintenance, and repairs, which do not extend the asset’s life, are expensed as incurred. The Company capitalizes expenditures for software developed or obtained for internal use. These costs include personnel and related employee benefits expenses for employees who are directly associated with and who devote time to software development projects, and external direct costs of consultants and materials for developing the software. Software development costs that do not qualify for capitalization as well as costs related to minor upgrades and enhancements are expensed as incurred and recorded in the Consolidated Statements of Operations.

Maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets, or, in the case of leasehold improvements, over the term of the lease or economic life, whichever is shorter as follows:

Assets Depreciable Life

Aircraft, equipment and rotable spares 3 to 20 years

Leasehold improvements Shorter of the estimated lease term or 5 years

Office, vehicles and ground equipment 3 years and 5 years

Internal-use software 3 years

Depreciation of property and equipment is included within Depreciation and amortization on the Consolidated Statements of Operations. When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any gain or loss is included in the Consolidated Statements of Operations.

Intangible Assets

Intangible assets consist primarily of EAS contracts, tradenames and trademarks and software acquired in an asset acquisition. The Company capitalizes expenditures for major software purchases.

The Company amortizes finite-lived intangible assets on a straight-line basis over their estimated useful lives, which range from two to ten years. The straight-line recognition method approximates the manner in which the expected benefits will be derived.

Impairment of Long-Lived Assets

Long-lived assets such as property and equipment, finite-lived intangible assets, and right of use assets are reviewed for impairment, whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.

The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The amount of impairment loss, if any, is measured as the difference between the carrying value of the asset and its estimated fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as appropriate. No impairment charges were recorded during the years ended December 31, 2024 and 2023.

Goodwill

Goodwill, which represents the excess of the cost of an acquired entity over the fair value of the acquired net assets, has an indefinite life and, accordingly, is not amortized. The Company tests goodwill for impairment annually, during the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset may be impaired.

The Company assesses goodwill for impairment utilizing either a qualitative assessment or a quantitative assessment by comparing the fair value of its reporting unit with its carrying amount. If the Company decides that it is appropriate to perform a qualitative assessment and concludes that the fair value of its reporting unit more likely than not exceeds its carrying value, no further evaluation is necessary. If the Company performs the quantitative assessment, the Company will compare the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its fair value, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds its reporting unit’s fair value.

The Company performed its annual goodwill impairment assessment on a qualitative basis as of October 1, 2023, and concluded that it was not more likely than not that the fair value of the reporting unit was less than its carrying value. This conclusion was primarily based on the operations of Southern being consistent with forecasts existing as of the acquisition date and the Company’s plans to re-fleet and expand Southern’s operations. Subsequent to this analysis, the Company identified indicators of impairment of the Southern reporting unit as of December 31, 2023. This was based on operational challenges that were expected to be remediated in the fourth quarter, such as: additional delays of aircraft maintenance due to the unavailability of parts, which resulted in a higher cancellation rate of scheduled flights. These delays were expected to, and did, continue into 2024. Additionally, the Company incurred higher cash requirements than expected to fund the operations of Southern during the fourth quarter of 2023, primarily due to higher maintenance costs. Further, unplanned delays in aircraft deliveries under the Textron aircraft supply agreement, including December 2023 cancellations of both firm deliveries and additional purchase options, have delayed re-fleeting efforts. Indicators of impairment also include a decline in the market price of our common stock and corresponding continued decline in our market capitalization from the date of the Southern Acquisition. As a result, the Company performed a quantitative assessment to compare the fair value of the reporting unit to its carrying amount as of December 31, 2023.The Company concluded that the carrying value of the Southern reporting unit exceeded its fair value and, as such, recorded a $60.0 million impairment of goodwill in its Southern reporting unit during the fourth quarter of 2023.

The Company estimated the fair value of its reporting units utilizing both a market approach and an income approach (discounted cash flow) and the significant assumptions used to measure fair value include discount rate, terminal value factors, revenue and EBITDA multiples, and control premiums. We evaluate our estimates under the income approach by reconciling the estimated fair value of the reporting unit determined under the income approach to our market capitalization and estimated fair value determined under the market approach.

This impairment charge is presented within impairment of goodwill on the Company’s Consolidated Statements of Operations. As of December 31, 2024 and 2023, the Company had no goodwill balance.

Deferred Revenue

The Company records deferred revenue (contract liabilities) when the Company receives customer payments in advance of the performance obligations being satisfied on the Company’s contracts. The Company generally collects payments from customers in advance of services being provided. The Company recognizes the deferred revenue as revenue when it meets the applicable revenue recognition criteria, which is usually either over the contract term, or when services have been provided. The Company generally meets performance obligations associated with all revenues deferred during the succeeding 12-month period. Accordingly, deferred revenue is classified within current liabilities in the accompanying Consolidated Balance Sheets.

Leases

The Company leases aircraft, airport passenger terminal space, portions of and full aircraft hangars and other airport facilities, other commercial real estate and office space.

Operating Leases

Operating lease right-of-use assets and liabilities are recognized at the lease commencement date, which is the date the Company takes possession of the asset. Operating lease liabilities represent the present value of lease payments not yet paid. Operating lease right-of-use assets represent our right to use an underlying asset and are based upon the operating lease liabilities adjusted for prepayments or accrued lease payments, initial direct costs, lease incentives, and impairment of operating lease assets. To determine the present value of lease payments not yet paid, the Company estimates incremental borrowing rates based on the appropriate term and information available at lease commencement in determining the present value of lease payments including reasonably certain renewal periods. The Company recognizes the lease cost for operating leases on a straight-line basis over the lease term. Aggregate lease cost is recorded in Cost of Revenue and General and Administrative expenses on the Consolidated Statements of Operations. Additionally, tenant incentives used to fund leasehold improvements or any rent abatements are recognized when earned and reduce the operating right-of-use asset related to the lease.

Finance Leases

The Company measures finance lease right-of-use assets and finance lease liabilities initially at an amount equal to the present value at the beginning of the lease term of minimum lease payments during the lease term, excluding that portion of the payments representing executory costs (such as insurance, maintenance, and taxes to be paid by the lessor) including any profit thereon, with the corresponding liability recorded within the liabilities section of the balance sheet. During the lease term, each minimum lease payment is allocated by the lessee between a reduction of the liability and interest expense to produce a constant periodic rate of interest on the

remaining balance of the liability (the interest method). Finance lease right-of-use assets are depreciated in accordance with the Company’s property and equipment policy and is included within Depreciation and amortization on the Consolidated Statements of Operations. The corresponding lease liabilities are reduced as lease payments are made.

Revenue Recognition

Scheduled Revenue

Scheduled revenue is derived from scheduled passenger flights under the EAS program, membership subscriptions, and through passenger single seat sales.

The Company provides scheduled passenger flight service on certain routes which is subsidized by the U.S. DOT under the EAS program. The EAS program is enacted to ensure that small communities in the U.S. have the ability to maintain a minimum level of scheduled air services. The Company has contracts with the U.S. DOT that are typically in duration of 2-4 years and include commitments for the Company to provide passenger air service to certain locations for a specific number of times annually to each location. The Company generally bills the U.S. DOT on the first of the month following the prior month’s completed flights, and typically collects from the U.S. DOT within 12 to 14 days after billing. Revenue is recognized on a per-flight basis when the Company has fulfilled its commitment, generally as the flights are completed.

The Company offers Pay-As-You-Fly (“PAYF”) memberships to members. The members pay an annual membership fee, which enables the member to purchase single use vouchers for travel on the Company’s scheduled routes. Vouchers are sold in a package and generally expire twelve months after the purchase date. Vouchers are nonrefundable, not exchangeable for cash and may not be used for other Company services. The Company recognizes the upfront annual membership fee as well as amounts paid by members for the purchase of vouchers as flights are completed or expiration, where applicable, of the vouchers. The Company has determined the PAYF membership and vouchers to represent a single performance obligation.

The Company earns revenue from the passenger for scheduled flight service through sales of tickets for single seats. These sales are generally paid by credit card. The Company also earns revenue generated by third-party travel booking sites or travel agencies. Tickets are refundable within 24 hours of purchase for flights scheduled to take place more than one week out, or when flights or services are changed, interrupted, or otherwise canceled by the Company. The Company recognizes revenue when it meets the applicable recognition criteria, which is at the point in time when a flight is completed or when tickets expire (generally within one year from the date of purchase).

On-demand Revenue

The Company earns revenue from the passenger for charter flight services, operated through a combination of its own aircraft and those of third party operators. These sales are generally paid for by credit card or wire transfer. The Company generally does not offer refunds after 24 hours of purchase. The Company recognizes revenue when it meets the applicable recognition criteria, which is at the point in time when a flight is completed or when tickets expire (generally within one year from the date of purchase).

Other Revenue

The Company also earns revenue from various ancillary services such as those relating to baggage fees, reservation change fees, package freight fees, and pet-travel (carry-on) fees. These fees are earned when the services are performed, generally at the time of travel.

Principal vs Agent

The Company evaluates whether it is a principal or an agent in contracts involving more than one party by assessing whether it controls the specified flight services before they are transferred to its customers. In transactions where the Company directs third-party air carriers to provide flights service to its customers, the Company determined it acts as the principal as it controls the services provided to the customers. In these instances, the Company is primarily responsible for fulfillment of the obligation in the contract, has pricing discretion, has the authority to direct the key components of the service on behalf of the member or customer regardless of which third-party is used. Therefore, the Company reports revenue and the associated costs on a gross basis in the Consolidated Statements of Operations.

When the Company is not primarily responsible for the fulfillment of the flight services, it acts as an agent and therefore recognized revenue in the Consolidated Statements of Operations is net of amounts paid to third-party air carriers and operators that provide the services.

In transactions where the Company operates aircraft on behalf of a third party, the Company determined it acts as the agent as it solely carries out the services based on the direction of the third party in exchange for a fixed service fee as determined by the related services agreement. In these instances, the Company reports the service fee as fee revenue net of any operating costs incurred by the Company to perform these services.

Operating Expenses

Cost of Revenue

Cost of revenue consists of costs that are directly related to delivering the Company’s services and certain facility costs. Delivery of the Company’s services primarily comprise of aircraft maintenance, fuel, airport-related expenses, and fees paid to third-party air carriers for operating aircraft in providing flight services and platform infrastructure costs. Cost of revenue also includes facility costs representing leases expenses and operating costs for stations throughout the service network and personnel related costs, primarily salary and bonus. Cost of revenue excludes depreciation on property and equipment and amortization of finite-lived intangible assets.

Sales and Marketing

Sales and marketing expense consists primarily of personnel related and other costs in connection with the Company’s sales and marketing efforts. Advertising costs are expensed as incurred and were not material for the years ended December 31, 2024 and 2023, respectively. Sales and marketing excludes depreciation on property and equipment and amortization of finite-lived intangible assets.

Technology and Development

Technology and development expense consists of personnel and other costs related to technology development and management efforts including costs for third-party development resources, and allocations of overhead and facility costs. Technology cost also includes research and development cost associated with the Company’s hybrid electrification strategy. The Company’s technology and development efforts are focused on enhancing the ease of use and functionality of its Surf OS platform by adding new core functionality, services and other improvements, as well as the development of new products and services. Technology and development costs are expensed as incurred, except to the extent that such costs are associated with internal-use software development that qualify for capitalization, which are then recorded within Property and Equipment, net on the Company’s consolidated balance sheets. Technology and development excludes depreciation on property and equipment and amortization of finite-lived intangible assets.

General and Administrative

General and administrative expense consists of personnel related costs including salary, bonus, and share-based compensation for the Company’s executive, finance, facilities, and human resource teams and facility costs. General and administrative expenses also include professional fees and other corporate related expenses. General and administrative expenses exclude the depreciation on property and equipment and amortization of finite-lived intangible assets.

Share-Based Compensation

Options, RSPAs, and Warrants

The Company accounts for the issuance of stock options, restricted share purchase agreements (“RSPAs”), and warrants in the consolidated financial statements based on the grant date fair value of the awards. Issuances of RSPAs with promissory notes are accounted for as share options and are measured based on the grant date fair value of the option. The Company estimates the fair value of these awards using the Black-Scholes option pricing model. The grant date fair value of share-based awards with service-only conditions is recognized as expense on a straight-line basis in the consolidated statement of operations over the requisite service period, which is generally the vesting period ranging from 12 to 48 months. Forfeitures are recorded as they occur. For awards with performance conditions, the Company records compensation expense on a graded-vesting basis when it is deemed probable that the performance condition will be met. For awards with market conditions, the effect of the market conditions is reflected in the fair value measurement and expense, using an option pricing model, recognized on a graded-vesting basis, is not reversed to the extent that the market condition is not achieved. Additionally, awards granted to non-employees are accounted for using their grant date fair value, using Black Scholes option pricing model and are accounted for in the same manner as awards granted to employees.

Determining the fair value of share-based awards requires judgment. The Company’s use of option pricing models requires the input of subjective assumptions, including the fair value of shares of the Company’s common stock underlying the option award, the expected term of the option, the expected volatility of the Company’s common stock, risk-free interest rates, and the expected dividend yield of the Company’s common stock. The assumptions used in the Company’s option pricing model represent management’s best

estimates. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used the Company’s share-based compensation expense could be materially different in the future.

Awards granted prior to the Company's direct listing were valued using the historical volatility of the stock price of similar publicly traded peer companies. The expected term of options granted represents the period for which the options are expected to be outstanding and is estimated based on a midpoint between the end of the requisite service period and the contractual term of the options granted. The risk-free interest rate is derived from the U.S. Treasury yield curve in effect at the date of grant. The Company has not declared or paid dividends to date and does not anticipate declaring dividends. As such, the dividend yield has been estimated to be zero. The Company’s assumptions may change for future grants.

For awards granted prior to the Company’s direct listing, because there was no public market for the Company’s common stock, the board of directors determined the fair value of the shares of common stock by considering a number of objective and subjective factors including the results of third-party valuations, the Company’s actual operating and financial performance, market conditions and performance of comparable publicly traded companies, developments and milestones in the Company, the likelihood of achieving a liquidity event and transactions involving the Company’s preferred or common shares, among other factors. The fair value was determined in accordance with applicable elements of the practice aid issued by the American Institute of Certified Public Accountants, Valuation of Privately Held Company Equity Securities Issued as Compensation.

Restricted Stock Unit Awards

The grant date fair value of RSUs is estimated based on the fair value of the Company’s common stock on the date of grant. Prior to the Company’s direct listing in July 2023, RSUs granted by the Company vested upon the satisfaction of both service-based vesting conditions and liquidity event-related performance vesting conditions. The liquidity event-related performance vesting conditions were achieved upon the consummation of the Company's direct listing. Stock-based compensation related to such awards was recorded in full, as of the date of the Company’s direct listing. Since the Company’s direct listing in July 2023, the Company has only granted RSUs that vest upon the satisfaction of a service-based vesting condition and the compensation expense for these RSUs is recognized on a straight-line basis from the date of grant over the requisite service period.

The Company has granted founder performance-based restricted stock units (“founder PRSUs”) that contain a market condition in the form of future stock price targets. The grant date fair value of the founder PRSUs was determined using a Monte Carlo simulation model and the Company estimates the derived service period of the founder PRSUs. The grant date fair value of founder PRSUs containing a market condition is recorded as stock-based compensation over the derived service period. Provided that each founder continues to be employed by the Company, either directly or as a non-employee consultant, stock-based compensation expense is recognized over the derived service period, regardless of whether the stock price goals are achieved. If the stock price goals are met sooner than the derived service period, any unrecognized compensation expenses related to the founder PRSUs will be expensed during the period in which the stock price targets are achieved.

Warrants

The Company assesses whether warrants issued to purchase the Company’s common stock are liability or equity-classified based on the terms of the warrants. If the warrants are determined to be liability-classified, then the warrants are remeasured to fair value each period with changes in fair value recorded within Changes in fair value of financial instruments carried at fair value, net on the Consolidated Statements of Operations. The Company recognizes the fair value of liability-classified warrants within Other liabilities in its Consolidated Balance Sheets. If the warrants are determined to be equity-classified, then the initial fair value is recorded in Additional paid-in capital and the warrants are not remeasured thereafter.

The Company estimates the fair value of warrants to purchase its common stock and redeemable convertible preferred shares using the Black-Scholes option pricing model. Warrants are principally issued to lenders and non-employees, some of whom are related parties, in connection with debt and equity fundraising and debt restructuring activities.

Income Taxes

Income taxes are accounted for under the asset and liability method in accordance with U.S. GAAP. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statements carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The likelihood of realizing the tax benefits related to a potential deferred tax asset is evaluated, and a

valuation allowance is recognized to reduce that deferred tax asset if it is more likely than not that all or some portion of the deferred tax asset will not be realized.

The Company determines whether a tax position taken or expected to be taken in a tax return is to be recognized in the consolidated financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The amount recognized is subject to estimation and management judgment with respect to the likely outcome of each uncertain tax position. The amount that is ultimately sustained for an individual uncertain tax position or for all uncertain tax positions in the aggregate could differ from the amount recognized. For tax positions meeting the more likely than not threshold, the tax amount recognized in the consolidated financial statements is reduced by the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company recognizes interest and penalties accrued related to unrecognized tax benefits, if any, in its income tax provision in the accompanying Consolidated Statements of Operations.

Net Loss Per Share Applicable to Common Shareholders, Basic and Diluted

The Company calculates basic and diluted net loss per share applicable to common shareholders using the two-class method required for companies with participating securities. The Company considers preferred stock to be participating securities as the holders are entitled to receive dividends on a pari passu basis in the event that a dividend is paid on common shares.

Under the two-class method, basic net loss per share applicable to common shareholders was calculated by dividing the net loss available to common shareholders by the weighted-average number of shares of common shares outstanding during the period. For purposes of determining the number of weighted-average common shares outstanding, the Company has included issued and outstanding common shares, penny common share warrants, and vested RSPAs. Diluted net loss per share available to common shareholders was computed by giving effect to all potentially dilutive common share equivalents outstanding for the period. For purposes of this calculation, preferred stock, unvested RSUs, unvested RSPAs, stock options and warrants to purchase common shares were considered common share equivalents but had been excluded from the calculation of diluted net loss per share applicable to common shareholders as their effect was anti-dilutive. In periods in which the Company reports a net loss applicable to common shareholders, diluted net loss per share available to common shareholders is the same as basic net loss per share applicable to common shareholders, since dilutive common shares are not assumed to have been outstanding if their effect is anti-dilutive. The Company reported net loss applicable to common shareholders for the years ended December 31, 2024 and 2023.

Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company elected the fair value option to account for its debt instruments because the Company’s debt instruments contain a number of complex features that would have otherwise required bifurcated derivative accounting. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value measurements are based on a fair value hierarchy, based on three levels of inputs, of which the first two are considered observable and the last unobservable, which are the following:

Level 1 Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.

Level 2 Inputs other than quoted prices included in Level I, that are observable for the asset or liability, either directly or indirectly, such as quoted market prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3 Inputs are unobservable inputs that reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.

The Company measures the fair value of certain long-lived assets including finite-lived intangible assets on a nonrecurring basis, when such assets are acquired in a business combination or are required to be written down to fair value if impaired. Such fair values are classified within the fair value hierarchy, as the valuations contain significant unobservable inputs, including assumptions of the present value of future cash flows, the use of these assets, as well as estimated disposition value.

There were no assets measured at fair value on a recurring basis as of December 31, 2024 and 2023.

The carrying amounts of certain financial assets and liabilities, including restricted cash, other current assets, accounts receivable, accounts payable, accrued expenses, and amounts due to related parties approximate fair value because of the short maturity and liquidity of those instruments.

SAFE and Convertible Notes at Fair Value

The Company’s Simple Agreements for Future Equity notes (“SAFE”) and Simple Agreement for Future Equity with Tokens (“SAFE-T”) are financial instruments whereby an investor provides an investment into the Company, and the note is subsequently converted into a preferred equity security at a discount to the price paid by other investors when and if a preferred equity is issued through a qualifying capital raise. Due to certain provisions included in the agreements for these instruments, they are classified as liabilities as of December 31, 2024 and 2023.

The Company elected the fair value option for the convertible notes and SAFE financial instruments, which requires them to be remeasured to fair value each reporting period with changes in fair value recorded in Changes in fair value of financial instruments carried at fair value, net on the Consolidated Statements of Operations, except for change in the fair value that results from a change in the instrument specific credit risk which is presented separately within other comprehensive income. The fair value estimate includes significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The decision to elect the fair value option is determined on an instrument-by-instrument basis on the date the instrument is initially recognized, is applied to the entire instrument, and is irrevocable once elected. For instruments measured at fair value, embedded conversion or other features are not required to be separated from the host instrument. Issuance costs related to convertible securities carried at fair value are not deferred and are recognized as incurred within Interest expense on the Consolidated Statements of Operations.

For instruments measured at fair value granted before the Company’s direct listing, the fair values were based on the estimated values of the notes, warrants, and derivative upon conversion including adjustments to the conversion rates, which were weighted probability associated with certain events, such as a sale of the Company or becoming a public company. The estimated fair values of these financial liabilities were determined utilizing the Probability-Weighted Expected Return Method and is considered a Level 3 fair value measurement.

Recent Accounting Pronouncements

Adopted

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting, which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The updated standard is effective for fiscal periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 as of January 1, 2024.

Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40). The ASU requires public entities to disaggregate, in a tabular presentation, certain income statement expenses into different categories, such as purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The guidance is effective for fiscal years beginning after December 15, 2026, with early adoption permitted, and may be applied retrospectively. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and related disclosures.

Note 3. Business Combination

On July 27, 2023, the Company completed the acquisition of all issued and outstanding shares of Southern. The acquisition of Southern expands the Company’s regional airline network servicing U.S. cities across the Mid-Atlantic, Gulf South, Midwest, Rocky Mountains, West Coast, New England and Hawaii. Total consideration is comprised of $81.25 million of equity consideration, through the issuance of 2,321,423 shares of the Company’s common stock on close of the Southern Acquisition and $699 thousand of payments made by the Company to settle debt obligations of Southern, which were not assumed as part of the acquisition. As the transaction

closed prior to the Company’s listing on the NYSE on July 27, 2023, the fair value of the common stock issued to Southern stockholders was based on the opening trading price of the Company’s common stock on July 27, 2023 of $35.00 per share.

Subsequent to the issuance of shares of the Company’s common stock as purchase consideration, the Company repurchased 57,666 shares from employees for $1.3 million in satisfaction of employee tax withholdings related to such issuance.

The results of operations of Southern are included in the Company’s consolidated financial statements from the date of acquisition, July 27, 2023, through December 31, 2024.

The purchase consideration was preliminarily allocated and adjusted as follows (in thousands):

Preliminary Balance Measurement Period Adjustments Adjusted Balance

Prepaid expenses and other current assets 4,326 4,326

Finance lease right-of-use assets 303 303

Accrued expenses and other current liabilities 10,405 10,405

Current maturities of long-term debt 2,923 2,923

Operating lease liabilities, current 3,624 3,624

Finance lease liabilities, current 147 147

Due to related parties, current 1,853 1,853

Long-term debt, net of current maturities 24,123 24,123

Operating lease liabilities, long term 6,836 6,836

Finance lease liabilities, long term 175 175

Due to related parties, long term 1,864 1,864

Other noncurrent liabilities 37 37

The Company provisionally allocated the purchase price to tangible and identified intangible assets acquired and liabilities assumed based on the preliminary estimates of their fair values, which were determined using generally accepted valuation techniques based on estimates and assumptions made by management using the best available information.

Measurement period adjustments

The Company recorded measurement period adjustments to the provisional purchase price allocation due to additional information received since the acquisition date of July 27, 2023. The significant adjustments included a reduction to identified intangible assets for EAS route contracts and tradenames of $1.1 million, reductions in plant, property, and equipment of $0.3 million, increases in accounts receivable of $0.4 million, and an increase in deferred income tax liabilities of $0.9 million resulting from new information available to management that impacted the fair value of the assets acquired.

Goodwill represents purchase consideration in excess of the fair value of net assets acquired. Factors that contribute to the recognition of goodwill include increased synergies expected to be achieved from the integration of Southern, as well as the acquisition of a talented workforce. None of the goodwill, as initially recorded, is expected to be deductible for income tax purposes.

During the fourth quarter of 2023, the Company recorded an impairment of the goodwill initially recorded due to the identification of impairment indicators, such as additional delays of aircraft maintenance due to the unavailability of parts, which resulted in a higher cancellation rate of scheduled flights. These delays were expected to, and did, continue into 2024. Additionally, the Company incurred

higher cash requirements than expected to fund the operations of the Southern reporting unit during the fourth quarter of 2023, primarily due to higher maintenance costs. Further, unplanned delays in aircraft deliveries under the Textron aircraft supply agreement, including December 2023 cancellations of both firm deliveries and additional purchase options, have delayed re-fleeting efforts. The resulting goodwill impairment charge of $60.0 million was the result of comparing the fair value of the Southern reporting unit to its carrying value.

Following are details of the purchase consideration allocated to acquired intangible assets:

Asset Fair Value Weighted- AverageEstimated Useful Life

Tradename and Trademarks (2) 1,280 4 years

(1)

The fair value of EAS route contracts were determined using the income approach, specifically, the multi-period excess earnings method.

(2)

Corporate trade name and trademarks primarily relate to the Southern brand and related trademarks, respectively, and the fair values were determined by applying the income approach, specifically, the relief from royalty method.

The fair value of the identified intangible assets will be amortized over the assets’ estimated useful lives based on the pattern in which the economic benefits are expected to be received to depreciation and amortization expense.

The Consolidated Statement of Operations include the following revenue and net loss attributable to Southern from the date of acquisition, July 27, 2023, to December 31, 2023:
