This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q may be forward-looking statements. Statements regarding the Company’s future results of operations and financial position, business strategy and plans and objectives of management for future operations are forward-looking statements. Forward-looking statements may be identified by the use of words such as “estimate”, “plan”, “project”, “forecast”, “intend”, “will”, “expect”, “anticipate”, “believe”, “seek”, “target”, “designed to” or other similar expressions that predict or indicate future events or trends, although the absence of these words does not mean that a statement is not forward-looking. The Company cautions readers of this Quarterly Report on Form 10-Q that these forward-looking statements are subject to risks and uncertainties, most of which are difficult to predict and many of which are beyond the Company’s control, that could cause the actual results to differ materially from the expected results. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of financial and performance metrics, projections of market opportunity and market share, potential benefits and the commercial attractiveness to its customers of the Company’s products and services and the dependence on third-party partnerships in the development of hybrid-electric and fully-electric powertrains, and the potential success of the Company’s marketing and expansion strategies. These statements are based on various assumptions, whether or not identified in this Quarterly Report on Form 10-Q, and on the current expectations of the Company’s management, and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied upon by any investor as a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. These forward-looking statements are subject to a number of risks and uncertainties, including:

•the Company’s future ability to pay contractual obligations and liquidity will depend on operating performance, cash flow and ability to secure adequate financing;

•the Company’s limited operating history and that the Company has not yet manufactured any hybrid-electric or fully-electric aircraft;

•the powertrain technology the Company plans to develop does not yet exist;

•the inability to maintain and strengthen Surf Air’s brand and its reputation as a regional airline;

•any accidents or incidents involving hybrid-electric or fully-electric aircraft;

•the inability to accurately forecast demand for products and manage product inventory in an effective and efficient manner;

•the dependence on third-party partners and suppliers for the components and collaboration in the Company’s development of hybrid-electric and fully-electric powertrains, and any interruptions, disagreements or delays with those partners and suppliers;

•the inability to execute business objectives and growth strategies successfully or sustain the Company’s growth;

•the integration of business acquisitions may involve risks that could adversely affect the Company’s business, divert the attention of management, and dilute shareholder value.

•the Company will incur increased costs as a result of operating as a public company, and management will be required to devote substantial time to comply with the Company’s public company responsibilities and corporate governance practices.

•the inability of customers to pay for the Company’s services;

•the Company’s inability to obtain additional financing or access the capital markets to fund its ongoing operations on acceptable terms and conditions;

•the outcome of any legal proceedings that might be instituted against Surf Air, Southern or the Company;

•changes in applicable laws or regulations, and the impact of the regulatory environment and complexities with compliance related to such environment.

All forward-looking statements included herein attributable to the Company or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

Surf Air Mobility Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

(Unaudited)

Note 1. Description of Business

Organization

Surf Air Mobility Inc. (the “Company”), a Delaware corporation, is building a regional air mobility ecosystem that will aim to sustainably connect the world’s communities. The Company intends to accelerate the adoption of green flying by developing, together with its commercial partners, hybrid-electric and fully-electric powertrain technology to upgrade existing fleets, and by creating a financing and services infrastructure to enable this transition on an industry-wide level.

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

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 New York Stock Exchange.

As the Internal Reorganization took place on July 21, 2023, the historical financial statements presented in this Quarterly Report on Form 10-Q 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.

Southern Acquisition

On July 27, 2023 (the “Acquisition Date”), immediately prior to the Company’s listing on the New York Stock Exchange 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 Southern Acquisition, Southern stockholders were to receive 16,250,000 shares of the Company's common stock, which was based on the aggregate merger consideration of $81.25 million at the $5.00 per share opening price on the first day of listing of the Company's common stock. In total, 16,249,963 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 Airways Corporation is a Delaware corporation that was founded on April 5, 2013, and together with its wholly owned subsidiaries Southern Airways Express, LLC, Southern Airways Pacific, LLC, Southern Airways Autos, LLC, and Multi-Aero Inc. is referred to hereafter collectively as “Southern.” 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 which operates a fleet of over 50 aircraft, including the Cessna Caravan, the Cessna Grand Caravan, the King Air Super 200, the Saab 340, 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.

Liquidity and Going Concern

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 Condensed Consolidated Balance Sheet as of September 30, 2023 and December 31, 2022. As discussed in Note 14, 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 beginning 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’s total outstanding federal excise tax liability including accrued penalties and interest of $7.0 million is included in accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheet as of September 30, 2023. 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 $1.9 million as of September 30, 2023. 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 September 30, 2023, the amount of property tax, interest and penalties related to the 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 September 30, 2023, 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 10, Financing Arrangements). The SAFE-T note is subordinate to the Company’s Convertible Note Purchase Agreement (see Note 10, 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 September 30, 2023.

In 2019, in connection with certain past due rental and maintenance payments under its aircraft leases totaling in aggregate approximately $5.0 million, which is accrued for at September 30, 2023 and December 31, 2022 as Other long-term liabilities on the Condensed Consolidated Balance Sheet, the Company entered into a payment plan pursuant to which all repayments of the past due amounts are deferred until such time as the Company receives at least $30.0 million in aggregate funds in connection with any capital contribution, at which time it is required to repay $1.0 million of such past due payments, with the eventual full repayment of the remaining amounts being required upon the receipt of at least $50.0 million in capital contributions. As of September 30, 2023, the Company has not made any payments under this payment plan.

The accompanying unaudited condensed 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 raise additional capital (or financing) to fund operating losses, refinance its current outstanding debt, maintain efficient aircraft utilization, primarily through the proper utilization of pilots and managing market shortages of maintenance personnel and critical aircraft components, sustain ongoing operations, attract and maintain customers, integrate, manage and grow recent acquisitions and new business initiatives, obtain and maintain relevant regulatory approvals, and measure and manage risks inherent to the business model.

In addition to the risks and uncertainties associated with the Company’s emerging and legacy business models, there continues to be a worldwide impact from the COVID-19 pandemic. The impact of COVID-19 has resulted in changes in consumer and business behavior, pandemic fears, market downturns, and restrictions on business and individual activities, which created significant volatility in global economy and has led to reduced economic activity particularly in the air travel industry. Due to enhanced virtual meeting and teleconferencing technology that has been adopted throughout the COVID-19 pandemic, more people are meeting over virtual meeting platforms than in person, which reduces the need for transportation. Specifically, COVID-19 related disruption in air travel has led to a decrease in membership sales, flight cancellations and significant operational volatility contributing to the Company defaulting on certain debt arrangements and amending the terms and conditions of certain debt arrangements, in order to meet liquidity needs (see Note 10, Financing Arrangements).

Prior to the quarter ended September 30, 2023, the Company has 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

9

share financing arrangements. During the quarter ended September 30, 2023, the Company received $8 million under a convertible note purchase agreement with Partners for Growth V, L.P. (“PFG”), $25 million through the Share Purchase Agreement with GEM Global Yield LLC SCS (“GEM”) and an entity affiliated with GEM that provides incremental financing (see Note 11, Share Purchase Agreement and GEM Purchase), and $4.5 million in advances under the Share Purchase Agreement with GEM (see Note 11, Share Purchase Agreement and GEM Purchase). On November 9, 2023, the Company filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission (the “SEC”) registering up to 300.0 million shares of the Company’s common stock, which represents the balance of the full amount of shares of common stock that the Company estimates could be issued and sold to GEM for advances under the Share Purchase Agreement, plus the amount of shares the Company estimates could be sold to GEM for $50 million under the Share Purchase Agreement.

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, 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, 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 hybrid-electric or fully-electric aircraft, or reducing funding of capital expenditures, which would 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 accompanying condensed 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.

Note 2. Summary of Significant Accounting Policies

Interim Financial Information

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the interim financial statements do not include all of the information and footnotes required by U.S. GAAP for annual financial statements and should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2022 and the related notes, as included in the Company’s Registration Statement on Form S-1 and Form S-4 filed on July 25, 2023. The information herein reflects all material adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the results for the period presented. The results for the nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023.

Except for the policies discussed below, there have been no material changes to the Company’s significant accounting policies, during the nine months ended September 30, 2023 from those disclosed in the notes to the Company’s consolidated financial statements for the year ended December 31, 2022.

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements include the assets, liabilities, and operating results of the Company. All intercompany balances and transactions have been eliminated in consolidation.

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 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 the purchase price of an acquisition, whichever comes first, any subsequent adjustments are recorded in the Consolidated Statements of Operations.

10

Accounts Receivable, net

Accounts receivable primarily consist of amounts due from the United States Department of Transportation (“U.S. DOT”) in relation to certain air routes served by the Company under the Essential Air Service (“EAS”) program, amounts due from airline and non-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 September 30, 2023, and December 31, 2022. The Company has considered past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

Collateralized Borrowings

The Company has a revolving accounts receivable financing arrangement that allows the Company to borrow up to 90% of eligible accounts receivable due from the U.S. DOT, in relation to certain air routes served by the Company under the EAS program, up to a maximum unsettled amount of $5 million. 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 balance sheet 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 Condensed 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 Condensed Consolidated Statements of Operations.

Restricted Stock Unit Awards

The grant date fair value of restricted stock units (“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 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. 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. Provided that each founder continues to be employed by the Company, stock-based compensation expense is recognized over the derived service period, regardless of whether the stock price goals are achieved.

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 has one reporting unit. The Company tests goodwill for impairment annually, or more frequently if events or changes in circumstances indicate that the asset may be impaired.

The Company reviews goodwill for impairment utilizing either a qualitative assessment or a fair value test 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 fair value test, 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.

Fair value estimates are subject to change as a result of many factors, including changes in business plans, economic conditions, and the competitive environment, among others. Should actual cash flows and the Company’s future estimates vary adversely from previous estimates, the Company may be required to recognize goodwill impairment charges in future years.

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

11

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 the corresponding lease liabilities are reduced as lease payments are made.

Use of Estimates

The preparation of the condensed 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 condensed 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 condensed 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 condensed consolidated financial statements.

Recent Accounting Pronouncements

Adopted

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Topic (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities (deferred revenue) from acquired contracts using the revenue recognition guidance in ASC 606. Under this “ASC 606 approach”, the acquirer applies the revenue model as if it had originated the contracts. This is a departure from the current requirement to measure contract assets and contract liabilities at fair value. Under current practice, measuring deferred revenue at fair value typically results in a reduction to the deferred revenue balance the acquiree had recorded before the acquisition. The reduction causes the acquirer to recognize less revenue than the acquiree would have absent an acquisition. The amendments in this ASU are applied to business combinations occurring on or after the effective date of the amendments. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods for public entities and for fiscal years beginning after December 15, 2023, including interim periods for nonpublic entities. The Company early adopted ASU 2021-08 as of January 1, 2023, and has applied and will apply this guidance to acquisitions after the date of adoption.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). This new credit losses standard changes the accounting for credit losses for certain instruments. The new measurement approach is based on expected losses, commonly referred to as the current expected credit loss (“CECL”) model, which is utilized to estimate lifetime “expected credit losses” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses and applies to financial assets including loans, held-to-maturity debt securities, net investment in leases, and reinsurance and trade receivables, as well as certain off-balance sheet credit exposures, such as loan commitments. The standard also changes the impairment model for available-for-sale debt securities. In November 2019, the FASB issued ASU 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), which updated the effective date of this credit loss standard to fiscal years beginning after December 15, 2022 for nonpublic entities, including interim periods within those fiscal years. The Company adopted ASU 2016-13 as of January 1, 2023, and the guidance did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

In September 2022, the FASB issued ASU No. 2022-04, Liabilities – Disclosure of Supplier Finance Program Obligations (Topic 425). This ASU creates a disclosure framework by which buyers in a supplier finance program will be required to disclose significant qualitative and quantitative information to allow a user of financial statements to understand the program’s nature and potential magnitude. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASU 2022-04 as of January 1, 2023, and assessed that the guidance does not have a material impact on the Company’s condensed 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 16,250,000 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 New York Stock Exchange 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 $5.00 per share.

Subsequent to the issuance of shares of the Company’s common stock as purchase consideration, the Company repurchased 403,667 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 condensed consolidated financial statements from the date of acquisition, July 27, 2023, through September 30, 2023.

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

Cash	$	1,377
Accounts receivable, net		4,155
Prepaid expenses and other current assets		4,326
Property and equipment, net		37,372
Operating lease right-of-use assets		13,214
Finance lease right-of-use assets		303
Acquisition-related intangibles		28,150
Other assets		3,604
Total assets	$	92,501
Accounts payable		5,649
Accrued expenses and other current liabilities		10,405
Deferred revenue		7,329
Current maturities of long-term debt		2,923
Operating lease liabilities, current		3,624
Finance lease liabilities, current		147
Due to related parties, current		1,853
Long-term debt, net of current maturities		24,123
Operating lease liabilities, long term		6,836
Finance lease liabilities, long term		175
Due to related parties, long term		1,864
Deferred tax liability		3,750
Other noncurrent liabilities		37
Total liabilities	$	68,715
Fair value of net assets acquired		23,786
Goodwill		58,163
Total Purchase Consideration	$	81,949

The Company 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. The fair values are subject to adjustment for up to one year after the close of the transaction as additional information is obtained. The primary items pending are related to income tax matters. Any adjustments to the preliminary purchase price allocation identified during the measurement period will be recognized in the period in which the adjustments are determined.

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 is expected to be deductible for income tax purposes. Goodwill is not amortized to earnings, but instead will be reviewed for impairment at least annually, absent any interim indicators of impairment.

13

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

Asset	Fair Value		Weighted- Average Estimated Useful Life
EAS Route Contracts (1)	$	26,830	10 years
Corporate Tradename and Trademarks (2)		1,320	4 years
Total	$	28,150

Note 11. Share Purchase Agreement and GEM Purchase

Share Purchase Agreement

During 2020, the Company entered into a Share Purchase Agreement (“SPA”) with GEM Global Yield LLC SCS (“GEM”) and an entity affiliated with GEM to provide incremental financing in the event the Company completed a business combination transaction with a special purpose acquisition company (“SPAC”), IPO, or direct listing. Pursuant to the SPA, GEM is required to purchase shares of the Company’s common stock at a discount to the volume weighted average trading price up to a maximum aggregate purchase price of $200.0 million, and in return the Company agreed to pay a total commitment fee of $4.0 million (the “Commitment Fee”) payable in installments at the time of each purchase of shares of the Company’s common stock or no later than one year from the anniversary of a public listing transaction and issued a forward contract for GEM to purchase 0.75% of the Company’s fully-diluted shares of common stock outstanding upon completion of a public listing transaction at an exercise price of $0.01 per share.

On May 17, 2022, February 8, 2023, and September 18, 2023, the SPA was amended to increase the maximum aggregate shares of the Company’s common stock that may be required to be purchased by GEM to $400.0 million (the “Aggregate Limit”) and increase the Commitment Fee to GEM to 4,000,000 shares of the Company’s common stock. Pursuant to the amended and restated SPA, and subject to the satisfaction of certain conditions, the Company, will have the right from time to time at its option to direct GEM to purchase up to the Aggregate Limit of shares of the Company’s common stock over the term of the amended and restated SPA. Upon its public listing, the Company may request GEM to provide advances under the SPA in an aggregate amount of up to $100.0 million, provided that individual advances are not to exceed $25.0 million each, with the first advance not to exceed $7.5 million. Each advance will reduce the amount that the Company can request for future purchases under the SPA. On September 29, 2023, the Company received its first advance under the SPA in the amount of $4.5 million, on a total request of $7.5 million, with the remaining $3.0 million being

22

received on October 3, 2023. Concurrent with the receipt of funds, the Company issued 4,000,000 shares of its common stock to GEM in full satisfaction of the commitment fee. The Company has deposited 18,000,000 shares of common stock into an escrow account as of September 30, 2023, as required under the SPA, which is intended to be at least two times the number of shares contemplated to settle the advance upon the close of the pricing period for the advance. The number of shares to be transferred to GEM will be based on an average of the volume-weighted average trading price of the Company’s common stock over a period of fifteen trading days following the receipt of an advance, subject to a fifteen day extension in certain circumstances. This average price will be subject to a contractual discount of 10%. Additionally, contractual provisions within the SPA provide that in no event may GEM receive a share issuance that would raise their share ownership percentage above 10% of the Company. This provision may impact the Company’s ability to request additional advances or execute additional purchases under the SPA.

On June 15, 2023, July 21, 2023, and July 24, 2023, the SPA was further amended to modify the number of shares of the Company’s common stock to be issued to GEM at the time of a public listing transaction of the Company from an amount equal to 0.75% of the Company’s fully-diluted shares of common stock outstanding to a fixed 1,300,000 shares of the Company’s common stock. The amendments to the SPA also modified certain registration requirements whereby the Company was obligated to file a re-sale registration statement within 5 business days of the Company’s public listing. On July 27, 2023, concurrent with the Company’s direct listing, the Company issued 1,300,000 shares of the Company’s common stock to GEM in full satisfaction of this provision. Pursuant to GEM’s associated registration rights, the Company filed a re-sale registration statement, covering the 1,300,000 shares, on August 2, 2023, which was declared effective by the Securities and Exchange Commission (“SEC”) on September 28, 2023.

The Company has accounted for the shares issuance contracts under the SPA, as amended, as derivative financial instruments which are recorded at fair value within Other long-term liabilities on the Condensed Consolidated Balance Sheets. As of September 30, 2023 and December 31, 2022, the fair value of the GEM commitment was $5.0 million and $3.0 million, respectively. Changes in fair value were recorded in Changes in fair value of financial instruments carried at fair value, net on the Condensed Consolidated Statements of Operations.

GEM Purchase

On June 15, 2023, and amended on July 21, 2023, and July 24, 2023, the Company and GEM entered into a share purchase agreement (the “GEM Purchase”) whereby GEM would purchase 1,000,000 shares of the Company’s common stock for cash consideration of $25.0 million upon the successful public listing of the Company’s shares. Under the terms of the agreement, the Company is obligated to file a re-sale registration statement, covering the 1,000,000 shares issued, within 5 business days of the Company’s public listing. On July 27, 2023, concurrent with the Company’s direct listing, the Company received the $25.0 million cash consideration contemplated in the purchase agreement, in exchange for the issuance of 1,000,000 shares of the Company’s common stock. Pursuant to the associated registration rights, the Company filed a re-sale registration statement, covering the 1,000,000 shares, on August 2, 2023, which was declared effective by the SEC on September 28, 2023.

Note 12. Fair Value Measurements

The fair values of the convertible notes, SAFE instruments, preferred stock warrant liabilities, and derivative liability were based on the estimated values of the notes, SAFE instruments, warrants, and derivatives upon conversion including adjustments to the conversion rates, which were probability weighted associated with certain events, such as a sale of the Company or the Company 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.

Significant unobservable inputs used in the valuation models as of September 30, 2023 and December 31, 2022 were as follows:

	September 30, 2023	December 31, 2022
Public listing probability	100%	50%
Lack of marketability	—%	32%
Discount rates used in the sale scenario for debt instruments	—%	70%
Discount rates used in the public listing scenario	—%	20 - 30%
Probability weighted volatility	—%	147%

23

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.

Note 13. Warrants

Preferred Share Warrants

Convertible Preferred Share Warrant Liability

There were no convertible preferred share warrants issued in the nine months ended September 30, 2023. The convertible preferred share warrants issued and outstanding as of December 31, 2022 were 805,823 shares of Class B-2 preferred warrants; 410,123 shares of Class B-3 preferred warrants; and 1,493,015 shares of Class B-4 preferred warrants. On July 21, 2023, as a condition of the Internal Reorganization, all preferred share warrants were converted into 120,935 warrants for the purchase of the Company’s common stock at a ratio of 22.4 Surf Air preferred warrants to 1 warrant for the purchase of the Company’s common stock. The exercise price for all warrants is $38.23 per share.

Warrants to purchase shares of convertible preferred stock were classified as Other long-term liabilities on the Condensed Consolidated Balance Sheets, as of December 31, 2022, and were subject to remeasurement to fair value at each balance sheet date with changes in fair value recorded in Changes in fair value of financial instruments carried at fair value through the date of the Internal Reorganization. As all converted warrants are for the purchase of common stock, and not preferred interests, the liability as of the date of the Internal Reorganization was reclassified to additional paid in capital.

Ordinary Share Warrants

Warrants were issued by Surf Air in connection with debt and equity capital raising transactions, as well as part of debt restructuring activities. The warrants were exercisable at any time, or from time to time, in whole or in part at any time on or prior to the expiration date, which was seven to ten years from the issuance date. The warrants terminated on the earlier of the expiration date or change in control upon the effectiveness of the Company’s registration statement or upon the closing of a deemed liquidation event. If there was no change in control, the warrants without a stated expiration date would never expire. On July 21, 2023, Surf Air merged into a subsidiary of the Company as part of an Internal Reorganization. The change in control resulted in all then outstanding ordinary share warrants being re-issued into warrants to purchase shares of the Company’s common stock.

Total outstanding ordinary share warrants issued by the Company were 0 and 4,614,651 as of September 30, 2023 and December 31, 2022, respectively. During 2023, the Company issued a total of 143,407 ordinary warrants due to the conversion of amounts due under the 2017 Convertible Notes (See Note 10, Financing Arrangements). During the nine months ended September 30, 2023, ordinary warrant holders exercised 4,758,058 ordinary warrants, with exercise prices ranging from $0.22 to $4.70 per share, on a combination of cash-based and cashless exercises. This resulted in the issuance of 4,707,562 shares of common stock for total proceeds of $128 thousand.

Note 14. Commitments and Contingencies

Software License Agreements

On May 18, 2021, the Company executed two agreements with Palantir Technologies Inc. to license a suite of software for the term of seven years commencing on the effective date. The agreements identify two phases where Palantir provides services to customize the software: an Initial Term from May 18, 2021 through June 30, 2023 with a cost of $11.0 million and an Enterprise Term from July 1, 2023 to May 7, 2028 with a cost of $39.0 million, for a total cost of $50.0 million. As of September 30, 2023 and December 31, 2022, the Company capitalized $2.4 million and $2.0 million, respectively, related to the software that Palantir has provided to the Company.

Licensing, Exclusivity and Aircraft Purchase Arrangements

Textron Agreement

On September 15, 2022, the Company entered into agreements with Textron Aviation Inc. and one of its affiliates (collectively, “TAI”), for engineering services and licensing, sales and marketing, and aircraft purchases, which are only effective as of the first trading date of shares of the Company’s common stock on a national securities exchange (“TAI Effective Date”). The agreements became effective as of the Company’s direct listing on July 27, 2023.

The engineering services and licensing agreement provides, among other things, that TAI will provide the Company with certain services in furtherance of development of an electrified powertrain technology (the “SAM System”). Under this agreement, the Company agrees to meet certain development milestones by specified dates, including issuance of a supplemental type certificate by the FAA. Should the Company fail to meet certain development milestones, TAI has the right to terminate the collaboration agreement.

The licensing agreement grants the Company a nonexclusive license to certain technical information and intellectual property for the purpose of developing an electrified propulsion system for the Cessna Grand Caravan aircraft, and to assist in obtaining Supplemental Type Certificates (“STC”) from the Federal Aviation Administration (“FAA”), including any foreign validation by any other aviation authority, for electrified propulsion upfits/retrofits of the Cessna Grand Caravan aircraft. The licensing agreement provides for payment by the Company of license fees aggregating $60.0 million over a multi-year period, with an initial $5 million deposit being made as of September 30, 2023 and remaining payments of $7.5 million coming due in December 2023.

Under the sales and marketing agreement, the parties agreed to develop marketing, promotional and sales strategies for the specifically configured Cessna Grand Caravans and further agreed to: (a) include Cessna Grand Caravans fitted with the SAM system (the “SAM Aircraft”) in sales and marketing materials (print and digital) distributed to authorized dealers, (b) prominently display the SAM Aircraft on their respective websites and social media, (c) include representatives of the Company and TAI at trade show booths, (d) market the SAM Aircraft and conversions to SAM Aircraft to all owners of pre-owned Cessna Grand Caravans, and (e) not advertise or offer any third-party-developed electrified variants of the Cessna Grand Caravan. Certain technologies for aircraft propulsion are specifically carved out from TAI’s agreement to exclusively promote the SAM System for Cessna Grand Caravans. The sales and marketing agreement provides for payment by the Company of exclusivity fees aggregating $40.0 million, with certain amounts deferred such that the aggregate fee is payable over four years commencing on the earlier of the year after the Company obtains an STC for the SAM System on the Cessna Grand Caravan or the 5th anniversary of the TAI Effective Date. The Company’s obligation to pay exclusivity fees in any year may be offset, in whole or in part, based on the achievement of certain sales milestones of SAM Aircraft and Cessna Grand Caravans subsequently converted to a SAM System.

Under the aircraft purchase agreement, the Company may purchase from TAI 100 specifically configured Cessna Grand Caravans at prevailing market rates whereby the aggregate purchase price could be in excess of $300.0 million, with an option to purchase an additional 50 specifically configured Cessna Grand Caravans having an aggregate purchase price in excess of $150.0 million, over the course of 7 years. The final price to be paid by the Company will be dependent upon a number of factors, including the final specifications of such aircraft and any price escalations.

Jetstream Agreement

On October 10, 2022, the Company and Jetstream Aviation Capital, LLC (“Jetstream”) entered into an agreement (the “Jetstream Agreement”) that provides for a sale and/or assignment of purchase rights of aircraft from the Company to Jetstream and the leaseback of such aircraft from Jetstream to the Company within a maximum aggregate purchase amount of $450.0 million, including a $120.0 million total minimum usage obligation by the Company. The agreement may be terminated: (i) upon a termination notice by either party in the event that a material adverse change in the business of the other party is not resolved within 30 days of such notice; and (ii) as mutually agreed in writing by the parties. No transactions have been executed under this agreement as of September 30, 2023.

Business Combination Agreements

On May 17, 2022, the Company entered into a business combination agreement (the “Merger Agreement”) with Tuscan Holdings Corp II (“Tuscan”). On November 14, 2022, the Company and Tuscan mutually terminated the Merger Agreement. Pursuant to the terms of the mutually terminated Merger Agreement, the Company was obligated to issue to Tuscan 635,000 shares of the Company’s common stock or a combination of 600,000 shares of the Company’s common stock and $0.7 million in cash upon a triggering event, which was defined as a direct listing, IPO or a business combination with a SPAC.

On July 27, 2023, concurrent with the first day of listing of the Company’s common stock, the Company issued 635,000 shares of common stock to Tuscan in satisfaction of the terms of the mutually terminated Merger Agreement. Based on the $5.00 opening price

26

of the Company’s common stock, such shares have resulted in $3,175,000 of contract termination expense, included as part of other expense in the Company’s Condensed Consolidated Statement of Operations.

Guarantees

The Company indemnifies its officers and directors for certain events or occurrences arising as a result of the officer or director serving in such capacity. The term of the indemnification period is for the officer or director’s lifetime. The maximum potential future amount the Company could be required to pay under these indemnification agreements is unlimited. The Company believes its insurance would cover any liability that may arise from the acts of its officers and directors and as of September 30, 2023 the Company is not aware of any pending claims or liabilities.

The Company enters into indemnification provisions under agreements with other parties in the ordinary course of business, typically with business partners, contractors, customers, landlords and investors. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of its activities or, in some cases, as a result of the indemnified party’s activities under the agreement. These indemnification provisions sometimes include indemnifications relating to representations the Company has made with regards to intellectual property rights. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential future amount the Company could be required to pay under these indemnification provisions is unlimited.

Legal Contingencies

In 2017, the Company acquired Rise U.S. Holdings, LLC (“Rise”). Prior to the close of the acquisition, Rise Alpha, LLC and Rise Management, LLC (both of which are wholly-owned subsidiaries of Rise and hereinafter referred to as the “Rise Parties”), were served with a petition for judgment by Menagerie Enterprises, Inc. (“Monarch Air”), relating to breach of contract for failure to pay Monarch Air pursuant to the terms and conditions of a flight services agreement with Monarch Air, which occurred prior to the Company’s acquisition of Rise. The Rise Parties filed numerous counterclaims against Monarch Air, including fraud, breach of contract and breach of fiduciary duty. Rise, a subsidiary of the Company, was named as a party in the lawsuit. During 2018 and 2019, certain summary judgements were granted in favor of Monarch Air.

On November 8, 2021, the Rise Parties entered into a final judgment in respect of litigation to finally resolve all claims raised by Monarch Air and the Rise Parties agreed to pay actual damages of $1.0 million, pre-judgment interest of $0.2 million, attorneys’ fees of $0.06 million and court costs of approximately $0.003 million. Since then, Monarch Air has been conducting post-judgment discovery. The full settlement had been accrued within Accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets by the Company as of September 30, 2023 and December 31, 2022.

The Company is also a party to various other claims and matters of litigation incidental to the normal course of its business, none of which were considered to have a potential material impact as of September 30, 2023.

Tax Commitment

On May 15, 2018, the Company received notice of a tax lien filing from the IRS for unpaid federal excise taxes for the quarterly periods beginning 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 (“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’s total outstanding federal excise tax liability, including accrued penalties and interest, is recorded in Accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets and is in the amount of $7.0 million and $5.8 million as of September 30, 2023 and December 31, 2022, respectively.

During 2018, the Company 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 $1.9 million and $1.7 million as of September 30, 2023 and December 31, 2022, respectively.

Note 15. Disaggregated Revenue

The disaggregated revenue for the three and nine months ended September 30, 2023 and 2022 were as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,

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 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. Accordingly, deferred revenue is classified within Current liabilities in the accompanying Condensed Consolidated Balance Sheets.

The long-term performance obligations for contractually committed revenues, all of which is related to charter revenue, is recorded in Other long-term liabilities as of September 30, 2023, and December 31, 2022 in the amount of $2.2 million and $1.8 million, respectively.

Note 17. Stock-Based Compensation

2023 Equity Incentive Plan

Concurrent with the Company’s direct listing, the Company’s board of directors adopted the 2023 Equity Incentive Plan (the “2023 Plan”), to provide an additional means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons. A total of 7,500,000 shares of the Company’s common stock were initially authorized for issuance with respect to awards granted under the 2023 Plan. Shares subject to outstanding awards granted under the 2016 Plan that are not paid, delivered or exercised before they expire or are canceled or terminated will be available for award grants under the 2023 Plan. In addition, the shares authorized for grant will automatically increase on the first trading day in January of each year (commencing with 2024) by an amount equal to lesser of (1) 5.0% of the total number of our outstanding shares on the last trading day in December in the prior year, or (2) such lesser number as determined by our board of directors. Any shares subject to awards that are not paid, delivered or exercised before they expire or are canceled or terminated, fail to vest, as well as shares used to pay the purchase or exercise price of awards or related tax withholding obligations, will become available for other award grants under the 2023 Plan.

Awards under the 2023 Plan may be in the form of incentive or nonqualified stock options, stock appreciation rights, stock bonuses, restricted stock, stock units and other forms of awards including cash awards.

The Company issues shares of common stock upon the vesting and settlement of RSUs and upon the exercises of stock options under the 2023 Plan. The 2023 Plan is administered by the Company’s board of directors, or a duly authorized committee of the Company’s board of directors.

2016 Equity Incentive Plan

Prior to the Company’s direct listing, the Company granted stock options, RSUs, RSPAs, and RSGAs to its employees, as well as nonemployees (including directors and others who provide substantial services to the Company) under the Company’s 2016 Equity Incentive Plan (the “2016 Plan”). Concurrent with the Internal Reorganization, all rights under previously granted RSPAs and RSGAs were converted into shares of the Company’s common stock, with the Company retaining certain rights of repurchase with respect to unvested RSPAs to coincide with grant-date service-conditions. Additionally, based on the original terms of the underlying awards, all RSUs granted under the 2016 Plan fully vested as of the direct listing date.

No further stock awards will be granted under the 2016 Plan now that the 2023 Plan is effective; however, awards outstanding under the 2016 Plan will continue to be governed by their existing terms.

2023 Employee Stock Purchase Plan

In conjunction with the Company’s direct listing, the Company’s board of directors adopted, and the Company’s stockholders approved the Company’s 2023 employee stock purchase plan (the “ESPP”). The Company’s ESPP authorizes the issuance of 800,000 shares of the Company’s common stock under purchase rights granted to the Company’s employees or to the employees of any of its designated affiliates. The number of shares of the Company’s common stock reserved for issuance will automatically increase on January 1 of each year for a period of 10 years, beginning January 1, 2024, by the lesser of (i) 1% of the total number of shares of the Company’s common stock outstanding on December 31 of the immediately preceding year; and (ii) 800,000 shares, except before the date of any such increase, the Company’s board of directors may determine that such increase will be less than the amount set forth in clauses (i) and (ii).

As of September 30, 2023, there had been no offering period or purchase period under the ESPP, and no such period will begin unless and until determined by the administrator, which is the Company’s board of directors or a duly authorized committee of the Company’s board of directors.

Management Incentive Bonus Plan

In conjunction with the Southern Acquisition, the Company’s board of directors adopted the Southern Management Incentive Bonus Plan (the “Incentive Bonus Plan”). The Incentive Bonus Plan provides select employees, consultants and service providers of the Company who were direct or indirect shareholders of Southern an incentive to contribute fully to the Company’s business achievement goals and success. The Incentive Bonus plan will provide for two tranches of bonus pools, to be allocated to covered employees based on participation units, which vest upon each employee’s continued employment by the Company and the achievement of certain revenue targets. Payments of amounts due under the Incentive Bonus Plan may be made in cash or shares of the Company’s common stock, at the Company’s option. Any shares to be issued under the Incentive Bonus Plan are excluded from the Company’s common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders. Due to current expectations of revenue targets being achieved, the Company has recorded $6.7 million of stock based compensation expense related to the Incentive Bonus Plan during the three months

29

ended September 30, 2023. Such amounts are included as a portion of Accrued expenses and other current liabilities within the Company’s Condensed Consolidated Balance Sheet.

Stock Options

Prior to the Company’s direct listing, the Company granted stock options to its employees, as well as nonemployees (including directors and others who provide substantial services to the Company) under the 2016 Plan, and subsequent to its direct listing, may grant similar awards under the 2023 Plan.

A summary of share option activity for the nine months ended September 30, 2023 is set forth below:

	Number of Share Options Outstanding			Weighted Average Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)		Weighted Average Exercise Price Per Share
Outstanding at December 31, 2022		1,768,205			9.01	$	10,306	$	3.58

Exercisable at September 30, 2023		1,188,490			8.03		641		3.77

Stock based compensation expense attributable to these awards was $0.8 million and $2.4 million for the three and nine months ended September 30, 2023, respectively. This compares to $0.2 million and $0.5 million for the three and nine months ended September 30, 2022, respectively.

Restricted Stock Units

As of December 31, 2022, the Company had 220,424 RSUs outstanding under the 2016 Plan, which were unvested with a weighted average grant date fair value of $3.75 per RSU. With the Company’s direct listing, all vesting criteria for all awards was achieved, resulting in the issuance of 260,424 shares of common stock for total compensation expense of $0.8 million during the three and nine months ended September 30, 2023.

During the three months ended September 30, 2023, the Company issued 280,454 RSUs under the 2023 Plan to employees and non-employee directors, which vest upon the satisfaction of certain service periods. The fair value of these RSUs was determined based on the Company’s stock price the business day immediately preceding the grant date. The service period of these RSUs is satisfied over a range of 12 months to 2 years. The RSUs are excluded from common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders.

A summary of RSU activity for the nine months ended September 30, 2023 is set forth below:

	Number of RSUs			Weighted Average Grant Date Fair Value per RSU
RSUs at December 31, 2022		220,424		$	3.75
Granted and vested		280,454			8.80
Shares issued		(260,424	)		4.53
Forfeited, cancelled, or expired		—			—
RSUs at September 30, 2023		240,454		$	8.80

Stock based compensation expense attributable to these awards was $1.8 million for both the three and nine months ended September 30, 2023 and 2023. This compares to $0 for both the three and nine months ended September 30, 2022.

Restricted Share Purchase Agreement

A summary of RSPA activity under the 2016 Plan for the nine months ended September 30, 2023 is set forth below:

	Number of RSPA			Weighted Average Grant Date Fair Value per RSPA
Unvested RSPAs at December 31, 2022		3,162,292		$	7.91
Granted		—			—
Vested		(2,696,004	)		8.56
Forfeited		—			—
Unvested RSPAs at September 30, 2023		466,288			4.12

On May 26, 2023, the Company approved the forgiveness of certain promissory notes associated with the issuance of RSPAs to executives and directors. The Company also provided cash bonuses to pay for interest and tax associated with the issuance of these shares in the amount of $0.1 million. The forgiveness of these promissory notes resulted in an immaterial additional stock based compensation expense as of September 30, 2023.

Prior to the Company’s direct listing, the Company’s board of directors determined that the remaining vesting requirements applicable to previously granted executive RSPA awards had been satisfied in connection with the Company’s direct listing. This resulted in the recognition of $21.8 million in previously unrecognized stock-based compensation expense during the three months ended September 30, 2023.

Stock-based compensation expense attributable to these awards was $22.8 million and $23.1 million for the three and nine months ended September 30, 2023, respectively. This compares to $0.3 million and $1.5 million for the three and nine months ended September 30, 2022, respectively.

Restricted Share Grant Agreement

As of December 31, 2022, there were 3,773,243 RSGA shares outstanding. As a result of the Internal Reorganization, on July 21, 2023, all outstanding RSGAs were converted and re-issued in the form of shares of the Company’s common stock, on a basis of 1 RSGA to 1 share of the Company’s common stock.

Stock based compensation expense attributable to these awards was $0 for the three and nine months ended September 30, 2023. This compares to $0 and $8.4 million for the three and nine months ended September 30, 2022, respectively.

Performance-Based Restricted Stock Units

In July 2023, the Company granted a total of 2,800,000 performance-based restricted stock units (“PRSUs”) to the Company’s founders (“Founder PRSUs”) under the 2023 Plan. The Founder PRSUs vest upon the satisfaction of a service condition and the achievement of certain stock price goals. The Founder PRSUs are excluded from the Company’s common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders.

The Founder PRSUs will vest only if (i) the per-share closing price of the Company’s common stock over a period of 10 consecutive trading days within five years from the date of the Company’s direct listing is greater than $10 per share and (ii) each founder’s employment with the Company or one of its subsidiaries continues through the date such stock price goal is achieved, subject to certain conditions.

The Company estimated the grant date fair value of the Founder PRSUs based on multiple stock price paths developed through the use of a Monte Carlo simulation model. A Monte Carlo simulation model also calculates a derived service period based on the expected time to achieve the defined stock price target, as described above. 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. An expiration term of 5 years (as defined in the grant agreements) was utilized. A volatility of 71.0 percent was determined, based on an established peer group over the maximum term to expiration. The weighted-average grant date fair

31

value of the Founders PRSUs was $2.28 per share. The Company will recognize total stock-based compensation expense of $6.4 million over the derived service period of 2.1 years as the founders satisfy the service-based vesting condition.

A summary of PRSU activity for the nine months ended September 30, 2023 is set forth below:

	Number of PRSUs		Weighted Average Grant Date Fair Value per PRSU
PRSUs at December 31, 2022		—	$	—
Granted		2,800,000		2.28
Shares issued		—		—
Forfeited, cancelled, or expired		—		—
PRSUs at September 30, 2023		2,800,000	$	2.28

Stock based compensation expense attributable to these awards was $0.5 million for both the three and nine months ended September 30, 2023. This compares to $0 for both the three and nine months ended September 30, 2022.

Note 18. Segments

Under the Segment Reporting topic of the Codification, disclosures are required for operating segments that are regularly reviewed by the Company’s chief operating decision maker. Following the closing of the Southern Acquisition, and integration of the operations of Surf Air and Southern, the Company operates as a single reportable segment. All of our long-lived assets are located in the United States and revenue is substantially earned from flights throughout the United States.

Note 19. Income Taxes

The Company's provision for income taxes for the three and nine months ended September 30, 2023, was a ($3.6) million benefit resulting in an effective tax rate of 4.6% and 2.5%, respectively. The Company’s effective tax rate for both periods was lower than the federal statutory rate of 21% primarily due to the Company’s full U.S. federal and state valuation allowance. The Company's income tax provision for the three and nine months ended September 30, 2022, was immaterial. The Company’s 0% effective tax rate for both periods was lower than the federal statutory rate of 21% due to the Company’s full U.S. federal and state valuation allowance.

As a result of the Southern Acquisition, the Company recorded $3.7 million in acquired net deferred tax liabilities primarily related to the excess of book basis over tax basis of the acquired intangible assets. In recording the deferred tax liability, the Company recorded a partial release of the valuation allowance on the Company’s net deferred tax assets, resulting in a discrete tax benefit for federal and state income taxes of $2.7 million and $0.8 million, respectively.

The Company is subject to income tax examinations by the U.S. federal and state tax authorities. There were no ongoing income tax examinations as of September 30, 2023. In general, tax years 2011 and forward remain open to audit for U.S. federal and state income tax purposes.

Note 22. Net Loss per Share Applicable to Ordinary Shareholders, Basic and Diluted

The Company calculates basic and diluted net loss per share attributable to ordinary 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 ordinary shares. As outlined in “Internal Reorganization” in Note 1, Description of Business, the effects of conversions at a ratio of 22.4 Surf Air shares to 1 share of the Company’s common stock, have been applied to outstanding common shares and rights to receive common shares for all periods presented in calculating earnings per share and for presentation within the Condensed Consolidated Statement of Changes in Redeemable Convertible Preferred Shares and Shareholders’ Deficit.

The following table sets forth the computation of net loss per ordinary share (in thousands, except share data):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2023			2022			2023			2022
Net loss	$	(74,609	)	$	(21,140	)	$	(139,702	)	$	(50,540	)

Item 2. 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 were comprised of 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 1. Financial Statements in this Quarterly Report on Form 10-Q. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, 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 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 the Company’s Registration Statement on Form S-1 filed on November 9, 2023 (the “Registration Statement”).

Overview of the Business

Surf Air Mobility Inc. (the “Company”), a Delaware corporation, is building a regional air mobility ecosystem that will aim to sustainably connect the world’s communities. The Company intends to accelerate the adoption of green flying by developing, together with its commercial partners, hybrid-electric and fully-electric powertrain technology to upgrade existing fleets, and by creating a financing and services infrastructure to enable this transition on an industry-wide level.

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

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 ordinary 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 New York Stock Exchange.

As the Internal Reorganization did not take effect until the quarter ended September 30, 2023, the historical financial statements presented in this Quarterly Report on Form 10-Q reflect the financial position, results of operations and cash flows of Surf Air, the predecessor to the Company, for all periods prior to the date of the Internal Reorganization.

Southern Acquisition

On July 27, 2023 (the “Acquisition Date”), immediately prior to the Company’s listing on the New York Stock Exchange 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 Southern Acquisition, Southern stockholders received 16,250,000 shares of the Company's Common Stock.

Southern, a Delaware corporation founded on April 5, 2013, and its wholly owned subsidiaries Southern Airways Express, LLC, Southern Airways Pacific, Southern Airways Autos, LLC, and Multi-Aero Inc. are collectively referred to hereafter as “Southern.” Southern is a scheduled service commuter airline serving cities across the United States that is headquartered in Palm Beach, Florida

37

and commenced flight operations in June 2013. It is a certified Part 135 operator which operates a fleet of over 50 aircraft, including the Cessna Caravan, the Cessna Grand Caravan, the King Air Super 200, the Saab 340, the Pilatus PC-12, the Tecnam Traveller, and the Citation Bravo. Southern provides both seasonal and full-year scheduled passenger air transportation service in the Mid-Atlantic and Gulf regions, Rockies and West Coast, Far Pacific, and Hawaii, with select routes subsidized by the United States Department of Transportation (“U.S. DOT”) under the Essential Air Service (“EAS”) program.

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

The results of operations of Southern are included in the Company’s condensed consolidated financial statements from the date of acquisition, July 27, 2023, through September 30, 2023. 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 Registration Statement, as well as the Form 8-K/A filed August 29, 2023.

2023 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 providing a delightful, premium flying experience and the Company expects these development expenses to continue to be incurred. Additionally, the Company is developing hybrid-electric and fully-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.

Beginning in early 2020, the effects and potential effects of the global COVID-19 pandemic, including, but not limited to, its impact on general economic conditions, trade and financing markets, changes in customer behavior with regard to air mobility services, and continuity in business operations created significant uncertainty for the Company. The Company has seen some recovery in on-demand flights from 2021 through the third quarter of 2023, however the Company’s business has been and will continue to be affected by many changing economic and other conditions beyond the Company’s control, including global events that affect travel behavior. The spread of COVID-19 also disrupted the manufacturing, delivery and overall supply chain of aircraft manufacturers and suppliers and has led to a global decrease in aircraft sales in markets around the world. 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 2022 and 2023 and believes perceived recessionary risks may impact 2023 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 the third quarter of 2023 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.

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 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.

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.

Components of the Company’s Results of Operations

The key components of our results of operations include:

Revenue

The Company’s revenue is comprised of scheduled flight services and on-demand trips.

Scheduled Revenue

Scheduled revenue is derived from EAS, passenger single seat purchases, membership subscriptions principally relating to two main categories of membership subscriptions: All You Can Fly (“AYCF”) and Pay As You Fly (“PAYF”), and other revenue.

EAS revenue is derived from operating scheduled passenger flight service on certain routes, which are subsidized by the U.S. DOT under its EAS program. The EAS program was enacted in 1978 to ensure small communities in the United States can maintain a minimum level of scheduled air services. Contracts under this program are typically two to four years in duration and include commitments to fly a specific number of times annually to each location. Revenue from EAS subsidies is recognized monthly. Revenue from sales of tickets on flights subsidized by the EAS program is recognized in direct passenger revenue and is recognized when the flights are completed.

Direct passenger revenue consists of single seat tickets for scheduled flight service. Tickets are refundable within 24 hours of purchase for flights scheduled to take place more than one week out, or when flights are changed, interrupted or otherwise canceled. Direct passenger sales revenues are recognized when the flights are completed or when tickets expire (generally within one year from the date of purchase).

AYCF membership subscriptions allow members to book unlimited flights over the contract service term (monthly or annually). The membership fee includes the subscription and single seat fees. AYCF membership fees are billed monthly in advance, and revenue is recognized on a month-to-month basis over the service term.

PAYF membership subscriptions allow members to purchase single use vouchers for travel on the Company’s scheduled routes. Vouchers sold in a package generally expire twelve months after the purchase date. Vouchers are nonrefundable, not exchangeable for cash and may not be used for other services. Revenue is recognized for the membership fee and the purchase of vouchers, based on the pattern of voucher usage, or at expiration, whichever comes first.

Other revenue is derived from various ancillary services related to baggage fees, reservation change fees and pet (carry-on) fees. These types of fees are standard within the aviation industry and are earned when the services are performed at the time of travel.

39

On-Demand Revenue

On-demand service allows customers to book an individual flight on routes specified by the customer. Customers can purchase single flights or prepaid, dollar based, credits. Single flights are paid for at booking. Flight credits are paid upon purchase and applied at booking.

The Company utilizes a combination of its own aircraft and FAA certified independent third-party air carriers in the performance of its charter flights on Surf Air. The Company evaluates whether it is a principal or an agent in contracts involving more than one party by assessing whether it controls the flight services before they are transferred to its customers.

The Company acts as the principal when it controls the services by directing third-party air carriers and operators to provide services to customers on its behalf. The Company controls the services when it is primarily responsible for fulfillment of the flight services obligation to the customer and has pricing discretion. In these arrangements, revenue recognized is the gross amount of the contract consideration paid by customers. When the Company is not primarily responsible for the fulfillment of the flight services, it acts as an agent and therefore recognized revenue is net of amounts paid to third-party air carriers and operators that provide the services. The majority of the On-Demand revenue was recognized on a gross basis. Customers purchase prepaid credits for on-demand services, and the revenue derived from these prepaid credits is recognized when the trip is flown.

Operating Expenses

Cost of Revenue, exclusive of depreciation and amortization

Cost of revenue consists of expenditures directly related to delivering services and related facility costs. Service delivery costs are primarily comprised of fees paid to the independent third-party air carriers operating both scheduled flight services and on-demand services when Surf Air is acting as the principal in the arrangement. Additionally, cost of revenue includes all personnel costs for pilots, member services and ground concierge staff. Aircraft expenses represent maintenance, materials, repairs, fuel, maintenance labor and aircraft leases to support the scheduled service network. Facility costs represent leases and operating costs for stations throughout the scheduled service network. Cost of revenue excludes depreciation and amortization. We anticipate that these costs will fluctuate in absolute dollars over time and as a percentage of revenue due to the anticipated growth of our business.

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. Technology and development efforts are focused on enhancing the ease of use and functionality of existing software platforms, 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 qualifies for capitalization. Technology and development expense excludes amortization of capitalized costs. We anticipate that these costs will fluctuate in absolute dollars over time due to the anticipated investment in software platforms.

Sales and Marketing

Sales and marketing expense consists primarily of personnel and other costs to support sales and marketing efforts. Personnel costs includes commissions, salaries and related benefits. Additionally, sales and marketing expense includes expenses associated with promotions of services, advertising and brand initiatives. We anticipate that these costs will fluctuate in absolute dollars over time and as a percentage of revenue due to the anticipated growth of our business.

General and Administrative

General and administrative expense consists of personnel-related costs for all business administrative functions. Additionally, stock-based compensation costs are included in this category for all personnel. Furthermore, professional fees, headquarter rents and other corporate related expenses are reflected in this category. We expect our general and administrative expenses to increase in absolute dollars over time and to fluctuate as a percentage of revenue due to the anticipated growth of our business and additional costs associated with being a public company.

Depreciation and Amortization

Depreciation expense consists primarily of depreciation of aircraft, aircraft parts, engines, furniture, fixtures and leasehold improvements. Amortization expense consists of amortization of capitalized software development costs, EAS contracts and brand and trademark intangibles.

40

Other Income/(Expense)

Other income/(expense) primarily consists of interest expense, changes in fair value of financial instruments, gain on extinguishment of debt and other non-operating costs. We expect these expenses to fluctuate in absolute dollars over time with the market or changes in timing and nature of debt costs. Certain convertible notes, SAFEs, and warrants were converted at listing and no longer require fair value measurement. The Company will continue to apply the fair value option, on an instrument by instrument basis, for similar type awards, as applicable.

Revenue

Revenue increased by $16.9 million, 332%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. The increase in revenue was attributable to the following changes in on-demand and scheduled revenues (in thousands, except percentages):

	Three Months Ended September 30,				Change
	2023		2022		$		%
Scheduled	$	15,547	$	996	$	14,551	NM
On-Demand		6,420		4,086		2,334		57	%
Total revenue	$	21,967	$	5,082	$	16,885		332	%
NM - Percentage change is not meaningful

Scheduled revenue increased $14.6 million, or 1,461% for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. The scheduled service, absent the impacts of the acquisition of Southern, remained flat period over period.

41

Of the increase in scheduled revenue, $14.5 million was related to the Southern Acquisition, primarily related to EAS revenue of $7.8 million, passenger revenue of $6.0 million, and other revenue of $0.7 million in the third quarter of 2023 after the acquisition of Southern.

On-demand revenue increased by $2.3 million, or 57%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. The Company conducted 926 on-demand flights during the three months ended September 30, 2023, and absent the impact of the acquisition of Southern, the Company conducted 681 on-demand charter flights during the third quarter of 2023 compared to 425 on-demand charter flights during the third quarter of 2022. The increase in on-demand charter flights was driven by increases in marketing efforts for our on-demand product and service strategy growth. Price per trip decreased during the third quarter of 2023 compared to the third quarter of 2022, primarily driven by a shift in customer preference to less expensive aircraft to service charter trips in 2023. These variables accounted for roughly $1.7 million, or 74% of the total on-demand revenue increase period over period.

With the Southern Acquisition, on-demand revenue increased $0.6 million, or 26%, during the three months ended September 30, 2023, primarily from 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 $14.4 million, or 232%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. Of the total 926 on-demand charter flights, and absent the impact of the acquisition of Southern, the Company 681 on-demand charter flights in the three months ended September 30, 2023, an increase from 425 for the three months ended September 30, 2022, resulting in a $0.8 million increase, or 6% of the total.

With the Southern Acquisition, cost of revenue increased by $13.6 million, or 95%, during the three months ended September 30, 2023 primarily due to aircraft expenses of $7.6 million, pilot expenses of $3.2 million, customer care expenses of $1.8 million, station expenses of $0.5 million, reservation systems of $0.3 million, and passenger re-accommodation expenses of $0.2 million.

Technology and Development

Technology and development expenses increased by $2.1 million, or 294%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. The increase was driven primarily by the amortization of software expenses related to work with Palantir for $2.0 million.

Sales and Marketing

Sales and marketing expenses increased by $3.1 million, or 228%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022, primarily due to an increase in advertising and brand awareness expenses of $1.0 million. Additionally, there was a $1.9 million increase due to management compensation and bonuses earned, as well as a continued concerted effort to grow the on-demand product offering, requiring increased sales force and related commissions, of which $1.5 million is considered non-recurring.

With the Southern Acquisition, sales and marketing expenses increased by $0.3 million primarily attributable to marketing for scheduled revenue.

General and Administrative

General and administrative expenses increased by $48.0 million, or 631%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. The increase in general and administrative expense is driven primarily by the recognition of an additional $32.1 million in stock-based compensation expense, of which $21.8 million is tied to the Company’s direct listing and is considered non-recurring. Additional increases were due to $6.8 million in professional and advisory fees related to the Company’s direct listing and is considered non-recurring, and $6.0 million in labor and labor-related expenses due to management compensation and bonuses earned, of which $3.1 million is considered non-recurring.

42

With the Southern Acquisition, general and administrative expenses increased by $3.1 million primarily attributable to labor expenses, professional fees, insurance, utilities, rent and travel.

Depreciation and Amortization

With the Southern Acquisition, depreciation and amortization expenses increased by $1.1 million, or 430%, for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. This was primarily due to additional engines and aircraft parts, as well as intangibles for EAS contracts and brand name/trademarks.

Other Income/(Expense)

Other expense, net increased by $5.1 million, or 51%, for the three months ended September 30, 2023compared to the three months ended September 30, 2022. There are two primary drivers for the increase in net income/(expense).

First, there was an increase in change in fair value of financial debt instruments carried at fair value of $1.2 million, mainly driven by an increase in the fair market value of SAFE notes issued by the Company of $3.3 million, and an increase in the fair market value of derivative liabilities of $2.1 million. These increases were offset by a decrease in the change in fair market value of certain convertible notes of $4.2 million. At the end of the third quarter 2022, the fair market valuation was based on the probability of a public listing for the Company at 25%. Fair market valuations during the third quarter of 2023 were based on a higher probability of public listing and/or actual equity values.

Secondly, other income/(expenses) increased $3.0 million from the three months ended September 30, 2022 to the three months ended September 30, 2023 primarily due to a $3.2 million stock-based payment to Tuscan in full satisfaction of the termination of a business combination agreement. This was offset by $0.2 million due to decreases in financial charges and other income.

Additionally, there was an increase in interest expense of $0.4 million period over period, due to additional related party term loans.

With the Southern Acquisition, other expenses increased by $0.5 million primarily attributable to interest expense associated with the debt instruments acquired from Southern.

Net Loss

The increase in net loss of $53.8 million from the existing business for the three months ended September 30, 2022 compared to the three months ended September 30, 2023, is primarily attributable to an increase in general and administrative expenses of $45.0 million, an increase in other expenses of $4.6 million (including changes in fair market value of financial instruments, interest expense, and other expense), an increase in technology and development of $2.1 million, an increase in sales and marketing of $2.9 million, and an increase in cost of revenue of $0.8 million. These increases in expenses were offset by an increase in $1.7 million in revenue.

With the Southern Acquisition net loss decreased by $0.3 million primarily attributable to cost of revenue of $13.6 million, general and administrative expenses of $3.2 million, depreciation and amortization of $1.1 million, interest expense of $0.5 million, and marketing expenses of $0.3 million. These increases in expenses were offset by an increase of $15.3 million in revenue and $3.6 million income tax benefit.

Non-GAAP Financial Measures

The Company uses Adjusted EBITDA to identify and target operational results which is beneficial to management and investors in evaluating operational effectiveness. Adjusted EBITDA is a supplemental measure of the Company’s performance that is not required by, or presented in accordance with, U.S. GAAP. Adjusted EBITDA is not a measurement of the Company’s financial performance under U.S. GAAP and should not be considered as an alternative to net income (loss) or any other performance measure derived in accordance with U.S. GAAP. The Company’s calculation of this non-GAAP financial measure may differ from similarly titled non-GAAP measures, if any, reported by other companies. This non-GAAP financial measure should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with U.S. GAAP.

Non-GAAP financial measures have limitations in their usefulness to investors because they have no standardized meaning prescribed by GAAP and are not prepared under any comprehensive set of accounting rules or principles. In addition, non-GAAP financial measures may be calculated differently from, and therefore may not be directly comparable to, similarly titled measures used by other companies.

43

The Company presents Adjusted EBITDA because it considers this measure to be an important supplemental measure of its performance and believes it is frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in its industry. Management believes that investors’ understanding of the Company’s performance is enhanced by including this non-GAAP financial measure as a reasonable basis for comparing its ongoing results of operations.

The Company calculates Adjusted EBITDA as net income (loss) adjusted for depreciation and amortization, interest expense, income tax expense, stock-based compensation, changes in fair value of financial instruments, gain on extinguishment of debt, transaction costs, and transaction bonuses.

The following table presents a reconciliation of Adjusted EBITDA to net loss for each of the periods indicated.

Cash Flow from Operating Activities

For the nine months ended September 30, 2023, net cash used in operating activities was $45.1 million, driven by a net loss of $140 million and increases in prepaid expenses and other current assets of $3.9 million. These operating outflows were partially offset by non-cash changes in fair value of financial instruments of $49.4 million, non-cash stock-based compensation expenses of $35.4 million, increases in accounts payable and other liabilities of $15.8 million, increases in depreciation and amortization of $0.8 million, and a loss on extinguishment of debt of $0.3 million. The acquisition of Southern resulted in net cash generated by operating activities of $0.8 million. This was driven by net income of $0.3 million, increases in accounts payable and other liabilities of $0.6 million, increases in depreciation and amortization of $1.1 million, and increases in non-cash operating lease expense of $0.8 million. These were mostly offset by a $3.6 million reduction in deferred income taxes and increases in prepaid expenses and other current assets of $2.4 million.

For the nine months ended September 30, 2022, net cash used in operating activities was $22.4 million, primarily driven by a net loss of $50.5 million, and a gain on extinguishment of debt of $6.0 million. This was partially offset by $10.5 million in non-cash stock-based compensation expenses, $20.1 million in changes in fair value of financial instruments, and accounts payable and other liabilities of $3.1 million.

Net cash used in operating activities increased period over period by $22.7 million, driven by a $89.2 million increase in net loss and increases in prepaid expenses and other current assets of $6.3 million. These were partially offset by an increase of $29.4 million in non-cash changes in fair value of financial instruments, increases of $24.9 million in non-cash stock-based compensation expenses, increases of $13.8 million in accounts payable and other liabilities, a $6.3 million increase in loss on extinguishment of debt, increases of $1.1 million in depreciation and amortization, and increases of $0.7 million in non-cash operating lease expense.

Cash Flow from Investing Activities

For the nine months ended September 30, 2023, net cash used in investing activities was $11.1 million, an increase of $10.9 million compared to the nine months ended September 30, 2022, driven by 10.0 million of cash paid for aircraft deposits, $1.6 million of property and equipment costs and a settlement of long-term debt of $0.7 million. These were offset by net cash received from the acquisition of Southern of $0.7 million.

Cash Flow from Financing Activities

For the nine months ended September 30, 2023, net cash provided by financing activities was $62.1 million from proceeds from the issuance of preferred shares, ordinary shares, and exercise of share options of $28.4 million, proceeds from borrowings of SAFE and convertible notes of $11.7 million, proceeds from borrowings due to related parties of $16.4 million, and proceeds from the GEM stock purchase agreement of $4.5 million and $0.7 million due to payments on long-term debt and amounts due under finance leases acquired from Southern.

For the nine months ended September 30, 2022, net cash provided by financing activities was $22.6 million from proceeds from borrowings of SAFE and convertible notes of $19 million, proceeds from borrowings due to related parties of $2.3 million, and proceeds from issuance of preferred shares of $1.3 million.

Net cash provided by financing activities increased period over period by $39.5 million, primarily driven by proceeds from the issuance of preferred shares, ordinary shares, and exercise of share options of $28.9 million, proceeds from borrowings due to related parties of $14.1 million, proceeds from GEM stock purchase agreement of $4.5 million, offset by proceeds from borrowings of SAFE and convertible notes of $7.3 million, and payments on long-term debt of $0.6 million.

Liquidity and Capital Resources

The Company has incurred losses from operations, negative cash flows from operating activities and has a working capital deficit. The Company is currently in default of certain excise and property taxes. 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 beginning 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 (“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’s total outstanding federal excise tax liability including accrued penalties and interest of approximately $7.0 million is included in accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheet as of September 30, 2023 and December 31, 2022. In May 2023, the Company made a payment to the IRS totaling $0.2 million. The Company intends to negotiate with the IRS to reduce the amount owed and/or apply for a revised installment plan for any amounts left remaining. 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 $1.9 million as of September 30, 2023. Of the total outstanding property tax liability, $1.1 million is from a tax lien from Los Angeles County for four of the Company’s aircraft due to the outstanding liability of its 2018 through 2022 property tax returns. The Company is in the process of remediating the late filing and payment of the proper tax due. The Company also owed the city of Hawthorne, California for past due business license fees from 2018 through 2022 in the total of approximately $0.2 million as of December 31, 2022, which, as of September 30, 2023, had been paid. Also, in connection with certain past due rental and maintenance payments under its aircraft leases totaling in aggregate approximately $6.0 million, the Company has entered into a payment plan pursuant to which all repayments of the past due amounts are deferred until such time as the Company receives at least $30 million in aggregate funds in connection with any capital contribution, at which time it is required to repay $1 million of such past due payments with an additional $1 million payment due when the Company receives at least $40 million in aggregate funds, with the eventual full repayment of the remaining amounts being required upon the receipt of at least $50 million in capital contributions. As of September 30, 2023, the Company has not made any payments under this payment plan.

The Company has previously defaulted on various debt and other obligations. During 2017, the Company entered into a loan and security agreement with a commercial lender (the “Lender”), which was subsequently amended and restated in 2018 (the “2017 Term Note”). In connection with these amendments, the Company issued the Lender warrants for a total of up to 4,291,884 Surf Air ordinary shares with an exercise price of $0.01 per ordinary share and expiration dates in 2027 and 2028. In September 2018 in connection with the payment of interest on behalf of the Company, the Company issued a warrant to LamVen for a total of up to 4,447,605 Surf Air ordinary shares with an exercise price of $0.01 per ordinary share and an expiration date of September 15, 2028. On January 31, 2019, the Company defaulted on its obligation to pay the principal and accrued interest due on the 2017 Term Notes. On April 7, 2020, the Company entered into a Forbearance Agreement with the Lender, under which the Lender agreed not to exercise any remedies that it had against the Company for any event of default in 2020. On May 1, 2020, the Company further defaulted on the payment of principal and interest required under the Forbearance Agreement and on May 31, 2021, the Company entered into an amendment to the 2017 Term Note under which (1) the Lender agreed to not exercise any remedies that it had against the Company for any event of default in 2020; (2) the maturity date of the 2017 Term Note was extended to December 31, 2021 (the “New Maturity Date”), and (3) interest accrued on the unpaid principal amount of the 2017 Term Note at 12.0%. Subsequent to the New Maturity Date, the outstanding balance of the 2017 Term Note was due on demand. In connection with the 2021 amendment, the Company issued to the Lender a warrant to purchase up to 16,168,295 Surf Air ordinary shares with an exercise price of $0.01 per ordinary share and expiration date of June 9, 2031. On May 17, 2022, the 2017 Term Note was converted, via a payoff letter, into a SAFE note, allowing for the purchase of a total of $15.2 million worth of the Company’s ordinary shares following a qualifying exchange event, defined as any qualified financing, IPO, direct listing, reverse merger, or change in control. The payoff letter provides that certain security interests in the Company shall immediately terminate upon the occurrence of an exchange event and the Lender will promptly thereafter file the appropriate termination statements with respect to such security interests. The payoff letter provided the Lender, in the event that a qualifying exchange event does not occur by December 31, 2022, an option to reinstate the indebtedness under the 2017 Term that was intended to be repaid by the SAFE note. On May 24, 2023, the payoff letter was amended to extend the option to exchange to July 31, 2023. As a result of the Company’s direct listing, all amounts due under this SAFE note were settled, on contractual terms, via the issuance of shares of the Company’s common stock.

Additionally, in April 2018, the Company entered into a SAFE-T note for $500 thousand with a financial institution which the Company defaulted on in July 2019. As of December 31, 2022, the Company remained in default on this SAFE-T note. This instrument was subordinate to the Convertible Note Purchase Agreement, and therefore had no recourse prior to payment of amounts due under the Convertible Note Purchase Agreement. In addition, in May 2020, the Company entered into a 6.25% convertible note with a vendor for approximately $541,000, which was subsequently amended in September 2020 and March 2021 to increase the amount of the note to approximately $633,000. In October 2022, the Company amended the note to re-instate the $5,000 monthly payment under the terms of the note. In April 2023, the Company amended the note to extend the maturity to November 1, 2023. As a result of the Internal Reorganization, all amounts due under this note were settled, on contractual terms, via the issuance of shares of the Company’s common stock.

49

As of May 31, 2023, the Company was also in default in the aggregate amount of approximately $0.1 million on payments under a payment plan entered into in relation to unpaid invoices, as well as certain amounts owed under judgments related to legal proceedings and claims arising in the ordinary course of its business. During September 2023, the Company made $0.1 million in payments to cure these defaults.

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 raise additional capital (or financing) to fund operating losses, refinance its current outstanding debt, maintain efficient aircraft utilization, primarily through the proper utilization of pilots and a managing market shortages of maintenance personnel and critical aircraft components, ,sustain ongoing operations, the ability to attract and maintain customers, the ability to integrate, manage and grow recent acquisitions and new business initiatives, obtain and maintain relevant regulatory approvals, and the ability to measure and manage risks inherent to the business model.

In addition to the risks and uncertainties associated with the Company’s emerging and legacy business models, there continues to be a worldwide impact from the COVID-19 pandemic. The impact of COVID-19 has resulted in changes in consumer and business behavior, pandemic fears, market downturns, and restrictions on business and individual activities, which created significant volatility in global economy and has led to reduced economic activity particularly in the air travel industry. Due to enhanced virtual meeting and teleconferencing technology that has been adopted throughout the COVID-19 pandemic, more people are meeting over virtual meeting platforms than in person, which reduces the need for transportation. Specifically, COVID-19 related disruption in air travel has led to a decrease in membership sales, flight cancellations and significant operational volatility contributing to the Company defaulting on certain debt arrangements and amending the terms and conditions of certain debt arrangements, in order to meet liquidity needs (see Note 10, Financing Arrangements).

Prior to the quarter ended September 30, 2023, the Company has 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 quarter ended September 30, 2023, the Company received $8 million under a Convertible Note Purchase Agreement with Partners for Growth V, L.P. (“PFG”), $25 million through a share purchase with GEM Global Yield LLC SCS (“GEM”) and an entity affiliated with GEM that provides incremental financing (see Note 11, Share Purchase Agreement and GEM Purchase), and $4.5 million in advances under the Share Purchase Agreement (see Note 11, Share Purchase Agreement and GEM Purchase). On November 9, 2023, the Company filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission (the “SEC”) registering up to 300.0 million shares of the Company’s common stock, which represents the balance of the full amount of shares of common stock that the Company estimates could be issued and sold to GEM for advances under the Share Purchase Agreement, plus the amount of shares the Company estimates could be issued and sold to GEM for $50 million of draw-downs under the Share Purchase Agreement. The Company is subject to customary affirmative covenants and negative covenants with respect to the Convertible Note Purchase Agreement. The Company as received a waiver from PFG regarding the maintenance of minimum cash requirement of $10 million. The waiver effectively waives the requirement through February 28, 2024. As of September 30, 2023, the Company was in compliance with all other covenants under the Convertible Note Purchase Agreement.

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, 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, 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 hybrid-electric or fully electric aircraft or reducing funding of capital expenditures, which would 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 accompanying condensed 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 2022 and the first nine months of 2023 were limited to payments made for aircraft supply deposits, aircraft parts, engines, immaterial purchases and internally developed software. Upon the Company’s ability to utilize the Share Purchase Agreement or obtain alternative funding, 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 $1.2 billion. The Company has placed an order

50

with TAI for 100 Cessna Grand Caravan aircraft with an option for an additional 50 Cessna Grand Caravan aircraft, with expected delivery taken over the next five years. As of September 30, 2023, the Company has made deposits of $10.0 million for aircraft that are scheduled to be delivered starting in Q2 2024. The Company intends to 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 SAM’s Financial Position and Capital Requirements — SAM has no operating history. Surf Air and Southern’s past financial results may not be a reliable indicator of SAM’s future success” included within the Registration Statement. The Company has engaged AeroTEC to develop hybrid-electric and fully electric STCs for the Cessna Grand Caravan in partnership with TAI. A portion of these costs are expected to be funded through the Share Purchase Agreement.

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) :

	Total		2023 (Remaining)		2024		2025		2026		2027		Thereafter

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.

Stock-Based Compensation

We grant stock options, 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.

51

Stock Options

We use the Black-Scholes option pricing model to estimate the fair value of the stock options 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 June 30, 2023, 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 will be based on the stock price on the day immediately preceding the date of grant, there will no longer be a 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”). The Founder PRSUs vest upon the satisfaction of a service condition and the achievement of certain stock price goals. We estimated the grant date fair value of the Founder 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 $2.26 per share, and we will recognize total stock-based compensation expense of approximately $6.3 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 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

52

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 based on its closing price as reported on the date of grant on the New York Stock Exchange.

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.

53

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 1, 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.

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 at of September 30, 2023.

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 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the ordinary course of operating our business, we are exposed to market risks. Market risk represents the risk of loss that may impact our financial position or results of operations due to adverse changes in financial market prices and rates. Our principal market risks have related to interest rates and aircraft fuel. Refer to the information included in the section entitled “Risk Factors” in the Company’s Registration Statement as well as in “Item 1A Risk Factors” in this Report.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) of the Exchange Act of 1934, as amended (the “Exchange Act”)), that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosure. It should be noted that, because of inherent limitations, our disclosure controls and procedures, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the disclosure controls and procedures are met.

As required by Rule 13a-15(b) under the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2023. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective at a reasonable assurance level as of September 30, 2023, due to presence of the material weaknesses in internal control over financial reporting described below.

Notwithstanding the pending remediation efforts described below, based on additional analysis and other post-closing procedures performed, our management believes that the financial statements included in this report present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP

Material Weaknesses in Internal Control Over Financial Reporting

As of September 30, 2023, material weaknesses existed in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses are as follows:

•We did not design and maintain an effective control environment commensurate with our financial reporting requirements. Specifically, we lacked a sufficient complement of resources with (i) an appropriate level of accounting knowledge, training and experience to appropriately analyze, record and disclose accounting matters timely and accurately, and (ii) an appropriate level of knowledge and experience to establish effective processes and controls. Additionally, the lack of a sufficient complement of resources resulted in an inability to consistently establish appropriate authorities and responsibilities in pursuit of our financial reporting objectives, as demonstrated by, among other things, insufficient segregation of duties in our finance and accounting functions.

•We did not design and maintain effective controls in response to the risks of material misstatement. Specifically, changes to existing controls or the implementation of new controls have not been sufficient to respond to changes to the risks of material misstatement to financial reporting.

These material weaknesses contributed to the following additional material weaknesses:

•We did not design and maintain effective controls related to the identification of and accounting for certain non-routine, unusual or complex transactions, including the proper application of U.S. GAAP of such transactions. Specifically, we did not design and maintain effective controls to timely identify and account for capitalizable costs, revenue, stock-based compensation, and debt and equity financing transactions.

55

•We did not design and maintain effective controls related to the period-end financial reporting process, including designing and maintaining formal accounting policies, procedures and controls to achieve complete, accurate and timely financial accounting, reporting and disclosures. Additionally, we did not design and maintain effective controls over the preparation and review of account reconciliations and journal entries, including maintaining appropriate segregation of duties.

•We did not design and maintain effective information technology (“IT”) general controls for information systems that are relevant to the preparation of our financial statements. Specifically, we did not design and maintain: (i) program change management controls to ensure that program and data changes are identified, tested, authorized, and implemented appropriately; (ii) user access controls to ensure appropriate segregation of duties and to adequately restrict user and privileged access to appropriate personnel; (iii) computer operations controls to ensure that processing and transfer of data, and data backups and recovery are monitored; and (iv) program development controls to ensure that new software development is tested, authorized and implemented appropriately.

These material weaknesses resulted in audit adjustments to substantially all of our accounts, which were recorded prior to the issuance of the consolidated financial statements as of December 31, 2021 and 2020 and for the years then ended, and as of June 30, 2022 and 2021 and for the six-month periods then ended. Subsequently, those material weaknesses also resulted in misstatements to accrued expenses, additional paid-in capital and stock-based compensation expense to the consolidated financial statements as of December 31, 2022 and for the year then ended. Additionally, these material weaknesses could result in a misstatement of substantially all of our accounts or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Additionally, with the closing of the Southern Acquisition, and the continued integration of associated operations and processes into those of the Company, the following material weakness in internal control over financial reporting has also been identified, after considering alignment with previous material weaknesses identified and outlined above:

•We did not design and maintain effective controls to achieve complete, accurate and timely accounting for debt, deferred liabilities, leases, property and equipment, redeemable convertible preferred shares, accounts payable, and accrued liabilities. This material weakness did not result in adjustments to our consolidated financial statements. However, this material weakness could result in a misstatement of the aforementioned accounts or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Additionally, prior to our acquisition of Southern, Southern reported multiple material weaknesses related to control environment, risks of material misstatement, period-end financial reporting and IT general controls in our Form S-1 filed on September 19, 2023.Those material weaknesses resulted in audit adjustments to substantially all of Southern’s accounts, which were recorded prior to the issuance of the consolidated financial statements of Southern as of December 31, 2022, 2021 and 2020 and for the years then ended. Subsequently, those material weaknesses also resulted in a revision to the previously issued consolidated financial statements of Southern as of December 31, 2022 and 2021 and for the years then ended, and the interim periods ended June 30, 2022 and 2021, to correct for errors in revenues and deferred revenues. Also, in connection with the preparation of Southern’s financial statements for the interim period ended March 31, 2023, Southern identified an error related to the accounting for prepaid passenger ticket deposits. Southern’s management determined that this error was the result of the previously reported material weaknesses. This error was corrected in Southern’s financial statements as of December 31, 2022 and 2021 and for the years then ended and the interim periods ended June 30, 2022 and 2021 as a revision to previously issued financial statements.

Remediation Plans to Address Material Weaknesses

To date, we have developed a plan to address the material weaknesses identified above. This remediation plan consists primarily of: (i) adding key personnel to strengthen the Company’s financial reporting processes, (ii) improving our internal controls around financial systems and processes, (iii) formalizing internal controls related to the identification of and accounting for certain non-routine, unusual or complex transactions, including the proper application of U.S. GAAP to such transactions, (iv) engaging a third party to assist in identifying risks of material misstatement and designing and implementing controls to address the identified risks of material misstatement. and (v) designing and operating computer operations, program and system development, and user access and change management controls. We intend to take additional steps to remediate the deficiencies identified above and further evolve our internal controls and processes.

Changes in Internal Control over Financial Reporting

Due to the acquisition of Southern, there were changes in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended September 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We are

56

currently in the process of integrating Southern’s operations, control processes and information systems into our systems and control environment.

Inherent Limitation on the Effectiveness of Internal Control over Financial Reporting and Disclosure Controls and Procedures

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected or preventable.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we are subject to various legal proceedings and claims, either asserted or unasserted, which arise in the ordinary course of business. While the outcome of these matters cannot be predicted with certainty, we do not believe that the outcome of any of these matters, individually or in the aggregate, will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

ITEM 1A. RISK FACTORS

As of the date of this Quarterly Report, there have been no material changes with respect to those risk factors previously described in our Registration Statement on Form S-1, filed on November 9, 2023 (File No. 333-275434). Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In the three months ended September 30, 2023, we sold 1,000,000 shares of common stock to GEM under the SPA and received proceeds of $25.0 million. The shares of common stock were issued in reliance upon the exemptions from the registration requirements of the Securities Act of 1933, as amended, afforded by Section 4(a)(2) thereof and Rule 506(b) of Regulation D promulgated hereunder.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

Exhibit 14.1

SURF AIR MOBILITY INC.

CODE OF CONDUCT AND ETHICS

Surf Air Mobility Inc. (the “Company”) believes that a strong commitment to high ethical, moral and legal principles in every aspect of the Company’s business is essential for our success. Accordingly, we have adopted this Code of Conduct and Ethics (the “Code”) that is applicable to each of the employees, officers and directors of the Company. We will make this Code available on our website at www.surfair.com.

Each of us is expected to read this document promptly upon receiving it and to act in accordance with the Code. No written policy can definitively set forth the appropriate action for all business situations, but this Code is designed to establish basic principles for you to follow. The use of good judgment, coupled with a high sense of personal integrity, is, of course, always the best policy.

This Code should be read in conjunction with other policies applicable to an employee, officer or director of the Company. In addition to the ethical guidelines included in this Code, there are many laws and regulations that affect us in each of the markets where we do business. Each of us must comply with the requirements of all applicable law. If a law conflicts with a policy in this Code, you must comply with the law. Those who violate the law or standards of this Code will be subject to disciplinary action, up to and including immediate dismissal and termination of employment, and may be subject to substantial civil damages and criminal fines. We may also face substantial fines and penalties and may incur damage to our reputation and standing in the community. If you are in a situation which you believe may violate or lead to a violation of this Code, you should ask your supervisor or the Company’s General Counsel, as the compliance officer for the Company (the “Compliance Officer”), how to handle the situation or follow the guidelines described in Section XVII below.

I.Personal Responsibilities of Employees, Officers and Directors

Each employee, officer and director must review this Code and sign the Employee Acknowledgment attached to this Code prior to or on his or her start date. All employees, officers and directors must review this Code carefully on an annual basis. All of us are expected to protect and enhance the assets and reputation of the Company. The honesty, integrity, sound judgment and professional and ethical conduct of the Company’s employees, officers and directors is fundamental to the reputation, functioning and success of the Company.

Accordingly, in carrying out our duties, we must:

oAct with honesty and integrity, including the ethical handling of any actual or apparent conflict of interest between personal and professional relationships;

oPromote full, fair, accurate, timely and understandable disclosure in the reports and documents that the Company files with, or submits to, the Securities and Exchange Commission (the “SEC”) and in other public communications made by the Company;

oEncourage and reward professional integrity in all aspects of our organization and eliminate barriers to responsible behavior, such as coercion, fear of reprisal or alienation from the Company;

Exhibit 14.1

oProvide for the education of all members of the Company about federal, state and local laws, rules and regulations and any applicable stock exchange rules relevant to the performance of their duties;

oComply and take all reasonable actions to cause the Company to comply with applicable governmental laws, rules and regulations and any applicable stock exchange rules;

oPromptly report violations of this Code, including any violations of governmental laws, rules or regulations, and any applicable stock exchange rules, to the Compliance Officer or any other appropriate person identified in this Code;

oEnsure accountability for adherence to this Code; and

oPromote ethical and honest behavior in the workplace.

II.Conflicts of Interest

A “conflict of interest” exists when a person’s private interests interfere—or appear to interfere— in any way with the interests of the Company. A conflict situation can arise when an employee, officer or director takes actions or has interests that may make it—or appear to make it—difficult to perform his or her Company work objectively and effectively. Conflicts of interest may also arise when an employee, officer or director, or members of his or her family, receives improper personal benefits, including material gifts or favors, as a result of his or her position in the Company. Loans to, or guarantees of obligations of, employees, officers, directors and their family members may create conflicts of interest.

Conflicts of interest may not always be apparent, so if you have a question regarding whether a particular situation is a conflict of interest, you should consult with your supervisor or the Compliance Officer. Any employee, officer or director who becomes aware of a conflict or potential conflict should bring it to the attention of a supervisor, manager or other appropriate personnel or follow the guidelines described in Section XVII below. Above all, the consistent use of good judgment by employees, officers and directors will help the Company avoid and prevent conflicts of interest.

This Code does not attempt to describe all possible conflicts of interest that could develop, but some of the more common conflicts from which employees, officers and directors must refrain are:

A.Assisting a Competitor or Competing Against the Company. An obvious conflict of interest is providing assistance to an organization that provides services in competition with the current or proposed services of the Company. Without the consent of the Board of Directors of the Company (the “Board”), employees, officers and employee-directors, during their employment with the Company, may not: (a) work for such an organization as an employee, consultant or member of its board of directors; or (b) have any ownership interest (excluding indirect interests through broad-based mutual funds or similar investment funds in which you exercise no discretion as to the choice of investment), in any enterprise which

Exhibit 14.1

competes with any business of the Company, except, solely in the case of a publicly-traded company, as a holder of less than one percent (1%) of the publicly traded stock in such a company. For the avoidance of doubt, non-employee directors are not subject to the foregoing restrictions in paragraphs (a) and

(b). Such activities are prohibited because they divide your loyalty between the Company and that organization. If you are an employee, officer or employee-director and your investments in such organizations increases to more than the one percent (1%) threshold as specified above, you must promptly report these investments in writing to the Compliance Officer. You may also not market services in competition with the Company’s current or proposed services. It is your responsibility to consult with your supervisor to determine whether any planned activity will compete with any of the Company’s actual or proposed product lines or services before you pursue the activity.

B.Supplying the Company. Generally, you may not be a supplier, vendor or business partner of the Company or represent or work for a supplier, vendor or business partner of the Company while you work for the Company. In addition, you may not accept money or benefits of any kind for any advice or services you may provide to a supplier, vendor or business partner in connection with its business with the Company, other than in accordance with the policies outlined in Section II. H. and Section IX of this Code.

C.Someone Close to You Working in the Industry. You may find yourself in a situation where your spouse, another member of your immediate family, or someone else you are close to is employed by a competitor, supplier, vendor or business partner of the Company. Such situations call for extra sensitivity to security, confidentiality and conflicts of interest because the closeness of the relationship might lead you to inadvertently compromise the interests of the Company. There are several factors to consider in assessing such a situation, including the relationship between the Company and the other company, the nature of your responsibilities as a Company employee and those of the person close to you, and the access each of you has to your respective employer’s confidential information. The very appearance of a conflict of interest can create problems, regardless of the behavior of the Company employee involved. You should review your specific situation with your supervisor to assess the nature and extent of any concern and how it can be resolved.

D.Loans, Guarantees and Other Personal Financial Transactions. The Company will not make any loans to, or guarantee any personal obligations of, employees, officers, directors or their respective family members. You should not enter into any material personal financial transactions with the Company except Company-related corporate transactions (such as a cashless exercise of stock options) or other transactions that have been cleared with the Company’s Chief Executive Officer (the “CEO”) or the Compliance Officer. You also should not obtain a material loan or guarantee of personal obligations from, or enter into any other material personal financial transaction with, any organization which competes with any business of the Company or is a material customer, supplier, vendor or business partner of the Company. This guideline does not prohibit arm’s-length or normal-course transactions with banks, brokerage firms or other financial institutions.

Exhibit 14.1

E.Family or Related Businesses. Potential transactions with family businesses or other businesses in which you participate as an owner, partner, director, officer, employee, consultant or shareholder, and which may create a conflict of interest or may interfere with your duties to the Company must be disclosed in writing to the Compliance Officer for approval. The appearance of favoritism, potential for conflict and likelihood of discouraging other service providers in the future will be considered carefully by the Compliance Officer before the transaction is approved.

F.Improper Conduct and Activities. You may not engage in any conduct or activities that are inconsistent with the Company’s best interests or that disrupt or impair the Company’s or its clients’ relationship with any person or entity with which the Company has or proposes to enter into a business or contractual relationship.

G.Compensation from Non-Company Sources. You may not accept compensation, in any form, for services performed for the Company from any source other than the Company. This provision is not intended to prevent members of our Board from having outside employment. However, each director must disclose to the Board any current or contemplated outside employment or similar relationships for the purpose of ensuring that no potential conflict of interest exists.

H.Gifts, Entertainment and Improper Payments. You and members of your family may not request or accept from, or offer, promise or give to, any person or entity dealing or desiring to deal with the Company, any payments, gifts, entertainment, services, travel, lodging, or any other forms of compensation for personal benefit. For these purposes, a “gift” generally does not include articles of nominal value ordinarily used for sales promotion, and “entertainment” does not include ordinary business meals or reasonable entertainment (including tickets for sports, concerts or similar events) considered to be a normal part of a business relationship that is accepted only on a very infrequent basis and that does not detract or have the appearance of detracting from the integrity of the relationship. Participation in entertainment activities should be with a representative of the vendor, supplier or other entity in attendance at the activity. Giving or receiving any payment or gift in the nature of a bribe, kickback or other improper influence is absolutely prohibited.

III.Responsibilities of the CEO and Senior Financial Officers

In addition to the matters set forth in the remainder of this Code, the CEO and senior financial officers are subject to the following additional specific policies:

A.Disclosure. The CEO and all senior financial officers are responsible for full, fair, accurate, timely and understandable disclosure in the periodic reports or documents required to be filed by the Company with the SEC. Accordingly, it is the responsibility of the CEO and each senior financial officer to promptly bring to the attention of the Compliance Officer and the Company’s Chief Financial Officer (the “CFO”) and to the Audit Committee any material information of which he or she may become aware that affects the disclosures made by the Company in its public filings or otherwise assist the Compliance Officer and the CFO in fulfilling the responsibilities specified in the Company’s applicable policies.

Exhibit 14.1

B.Internal Controls; Fraud. The CEO and each senior financial officer shall promptly bring to the attention of the Compliance Officer and the CFO and to the Audit Committee any information he or she may have concerning (a) significant deficiencies in the design and operation of internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data or (b) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s financial reporting, disclosures or internal controls.

C.Code of Conduct. The CEO and each senior financial officer shall promptly bring to the attention of the Compliance Officer and the CFO and to the Audit Committee any information he or she may have concerning any violation of this Code, including any actual or apparent conflicts of interest between personal and professional relationships, involving any management or other employees who have a significant role in the Company’s financial reporting, disclosure or internal controls.

D. Violations. The CEO and each senior financial officer shall promptly bring to the attention of the Compliance Officer and the CFO and to the Audit Committee any information he or she may have concerning evidence of a material violation of the securities or other laws, rules or regulations applicable to the Company and the operation of its business, by the Company or any agent thereof, or of violation of this Code.

IV.Insider Trading

Employees, officers and directors who have access to confidential information are not permitted to use or share that information for stock trading purposes except in the conduct of our business. All non- public information about the Company, its customers, vendors, suppliers, business partners and other firms the Company may be negotiating major transactions with, should be considered confidential information. To use non-public information for personal financial benefit or to “tip” others who might make an investment decision on the basis of this information is not only unethical, but also illegal. In order to assist in compliance with laws against insider trading, the Company has adopted a specific policy governing employees’, officers’ and directors’ trading in securities of the Company. This insider trading policy has been distributed to every employee, officer and director of the Company. If you have any questions, please consult the Compliance Officer.

V.Confidentiality; Privacy and Protection of Personally Identifiable Information

Employees, officers and directors must maintain the confidentiality of confidential information (including letters, memos and internal Company documents) entrusted to them by the Company and people with whom the Company interacts, including its vendors, suppliers, business partners and customers, except when disclosure is authorized by the Compliance Officer or required by laws or regulations. Confidential information includes all non-public information that might be of use to competitors, harmful to the Company and its vendors, suppliers, business

Exhibit 14.1

partners and customers, or otherwise subject to restrictions on disclosure by law. If an employee, officer or director leaves the Company, he or she must return to the Company all documents containing confidential information of the Company, whether in hard copy or electronic form, including without limitation all reports, information, and other materials relating to the Company’s pipelines and research projects. Employees, officers and directors are prohibited from copying, preserving, falsifying, deleting without authorization, transferring, or sending relevant reports, information, document materials or processes for their personal or other benefit. This prohibition and the obligation to preserve confidential information continues even after employment ends.

In addition, customers and other people with whom the Company comes in contact entrust the Company with their personal information, which is defined as any piece of personally identifiable information, including, but not limited to, such personal information as name, mailing address, e-mail address, phone number, credit card number, driver’s license number, social security number and information about health, race, religious beliefs, etc. The Company collects, processes, uses and retains personal information only in compliance with applicable laws. Employees, directors and officers are responsible for protecting this information both inside and outside of the Company and will do so in accordance with applicable laws, any data protection policies established by the Company and any extra standards required by contract. If personal information is to be transferred outside of any country, check to determine the necessity of a cross-border data transfer agreement. Internally, such information may only be disclosed for business purposes in accordance with applicable privacy laws. Externally, this information may not be disclosed.

Nothing in this section is intended to prohibit you from reporting, in a confidential manner, possible violations of a federal law or regulation to any governmental agency or entity where the Company operates, including but not limited to the Securities and Exchange Commission, or making other disclosures that are protected under the whistleblower provisions of state or federal law or regulation or otherwise participate in an investigation or proceeding conducted by such agency or entity, or to recover any award offered by such agency or entity associated with such report. You do not need the prior authorization of the Company to make any such reports or disclosures and you are not required to notify the Company that you have made such reports or disclosures.

VI.Corporate Opportunities

Employees, officers and directors are prohibited from taking for themselves, personally, or for the benefit of any related or affiliated person or entity, opportunities that properly belong to the Company or are discovered through the use of corporate property, information or position without the consent of the Board. No employee, officer or director may use corporate property, information or position for improper personal gain. No employee, officer or director may compete with the Company. Employees, officers and directors owe a duty to the Company to advance its legitimate interests when the opportunity to do so arises.

VII.Books and Records

The Company is a publicly-owned company. As such, the Company relies on the public securities markets for capital to fund our activities. The Company’s books and records are crucial to its business and form the basis of its financial statements and reports and other disclosures to

Exhibit 14.1

shareholders and the public. Public investors rely upon the quality and integrity of the Company’s financial statements, reports, press releases and other disclosures. Additionally, the Company’s books and records are a source of essential data that guide the business decision-making and strategic planning of the Company. Accordingly, it is imperative that the Company maintain accurate books and records and report its financial results and condition accurately.

A.Accuracy and Completeness. Each employee, officer and director must do his or her part to ensure that the books of account and financial records of the Company meet the highest standards of accuracy and completeness. This responsibility does not rest exclusively with the Company’s accounting personnel. There is never an acceptable reason to make false or misleading entries. Undisclosed or unrecorded funds, payments or receipts are strictly prohibited. If you have reason to believe that any of the Company’s books and records are not being maintained in an accurate or complete manner, or if you become aware of any breakdown in internal controls or in the Company’s filings or other communications, you are expected to report this immediately as described in Section XVII, or to the Compliance Officer or the CFO. Similarly, the Company relies on you to speak up if you ever feel or if you actually are being pressured to destroy documents which would not normally be destroyed, or if you become aware that any misleading, incomplete or false statement was made to an accountant, auditor, attorney or government official in connection with any audit, examination or filing with a government agency, such as the SEC.

B.Financial Statements and Accounts. All employees who are involved in supplying any kind of supporting documentation, determining account classification or approving transactions will be held responsible for ensuring that transactions are reported accurately, completely and in reasonable detail. All transactions must be recorded appropriately to ensure full accountability for all assets and activities of the Company and to supply the data needed in connection with the preparation of financial statements. Each employee involved in the preparation of the Company’s financial statements must prepare them in accordance with generally accepted accounting principles in the United States (“GAAP”) and other applicable standards and rules, so that the statements fairly and completely reflect the operations and financial condition of the Company.

C.Payments and Expense Accounts. No payment on behalf of the Company may be approved or made if any part of it is to be used for any purpose other than that described by the supporting documents. All receipts and disbursements must be fully and accurately described in the books and records of the Company and must be supported by appropriate descriptive documentation. Employees should request reimbursement for business-related expenses in strict accordance with the Company’s travel and entertainment policies.

D. Retention of Documents. Documents and records must be retained for the periods of time specified by the Company. Each employee, officer and director is responsible for understanding and complying with the Company’s document and record retention guidelines. Also, if you are aware of an imminent or ongoing investigation, audit or examination initiated by the Company or any government or

Exhibit 14.1

regulatory agency, you should retain all documents and records in your custody or control relating to the matter under review, even if the age of the records is beyond the Company’s retention guidelines. Please note that the knowing destruction or deliberate falsification of any document or data in order to impede a governmental or regulatory investigation, audit or examination may be the basis for immediate dismissal and termination of employment and may subject you to prosecution for obstruction of justice. If you are not sure that a document can be destroyed, consult your supervisor or the Compliance Officer.

VIII.Treatment of Employees

The Company has established comprehensive programs to ensure compliance with labor and employment laws, including equal employment opportunity policies and procedures, safety and health programs, and wage and hour procedures. For further information on particular labor and employment compliance policies, see the applicable sections of the Company’s Employee Handbook or contact the Human Resources Department.

A.Safety, Health and the Environment. The Company is committed to maintaining a safe work environment by eliminating recognized hazards in the workplace. The Company will, and you are required to, comply with all applicable environmental, health and safety (“EHS”) laws and regulations and with all related Company policies. The Company is committed to maintaining safe workplaces, reducing the environmental impact of our operations and encouraging environmentally sustainable business operations. This also applies to our vendors, suppliers and business partners who acknowledge our standards and commitments. Employees, officers and directors are responsible for adhering to the applicable EHS requirements and for taking the necessary precautions to protect themselves and their colleagues. In addition, you must report to work in a condition suitable for performing your duties, free from the influence of illegal drugs or alcohol. To further your own safety and that of your fellow employees, you are also required to report to your supervisor any unsafe conditions, hazards, broken equipment, accidents, violence and employees visibly under the influence of illegal drugs or alcohol.

B.Nondiscrimination and Equal Employment Opportunity. The Company is an equal opportunity employer that embraces and values a diverse workforce and pledges to provide equal employment opportunity to all job applicants and employees. We will not tolerate discrimination against applicants or employees based on any protected classification including without limitation their race, religion, color, gender, pregnancy, childbirth, or pregnancy-related conditions, age, marital status, national origin or ancestry, sexual orientation, citizenship status, disability or status as a disabled veteran. We require all employees to refrain from unlawful discrimination in any aspect of employment, including decisions concerning recruitment, hiring, termination, promotions, salary treatment, or any other term, condition or privilege of employment or career development. You must treat all employees, vendors, suppliers, business partners, contractors and customers of the Company and other people with whom we come in contact with respect, dignity and honesty. We will not tolerate the use of discriminatory slurs,

Exhibit 14.1

or any other remarks, jokes or conduct or other forms of harassment based on race, religion, color, gender, age, marital status, national origin or ancestry, sexual orientation, citizenship status, disability, status as a disabled veteran, or any other protected status.

C.Sexual and Other Forms of Harassment. The Company’s policy, as well as the applicable laws, strictly prohibits all forms of harassment, violence and threatening behavior in the workplace, including unlawful harassment based on race, religion, color, gender, pregnancy, childbirth, or pregnancy-related conditions, age, marital status, national origin or ancestry, sexual orientation, citizenship status, disability, status as a disabled veteran or any other protected class. This prohibition also applies to the harassment of Company employees by non-employees. Sexual harassment includes linking, either explicitly or implicitly, a person’s submission to, or rejection of, sexual advances to any decision regarding that person’s terms or conditions of employment. It also includes the existence of a sexually abusive or hostile working environment. This can be characterized by unwelcome sexual advances or verbal or physical conduct of a sexual nature. The Company prohibits retaliation against individuals who report suspected violations or who participate in the investigation of any complaints of sexual or other forms of harassment.

D.Reporting Responsibilities and Procedures. If you believe that you have been subjected to harassment of any kind or any other type of unlawful discrimination, or if you feel retaliated against because of filing a complaint, you should report the matter as described in Section XVII. Any manager who has knowledge of any incident of sexual or other prohibited forms of harassment is required to report such information to the Human Resources Department or a corporate officer. Complaints of harassment, abuse or discrimination will be taken seriously and investigated immediately and thoroughly by Human Resources. Investigations will be conducted as confidentially as possible. Employees found to have engaged in sexual harassment or any other kind of abusive behavior shall be subject to disciplinary action, which may include termination. However, false accusations of harassment also violate the Company’s policy.

IX.Business Partner Relations

The Company seeks to do business only with vendors, suppliers and other business partners who conduct business ethically and legally. You must use care and good judgment in selecting and maintaining relationships with all of the Company’s vendors, suppliers and other business partners. Employees, officers or directors who participate in the selection of any vendor, supplier or other business partner must use a selection process that is fair, lawful, does not improperly discriminate, and complies with all Company policies and procedures, and ensure that vendors, suppliers and other business partners are apprised of their obligation to abide by the Company’s standards of business documents.

X.Computer Use

Exhibit 14.1

All Internet, Intranet and e-mail activities are to be conducted for legitimate business purposes only. You acknowledge that, to the extent permitted by the applicable laws, the Company owns and has all rights to monitor, inspect, disclose and expunge all electronic files and records on Company systems, and that you should have no expectation of privacy with respect to all such files and records. Employee use and/or access of all Company computing resources, including computers, mobile phones and tablets, networked services and Internet and e-mail access (including web surfing), must at all times comply with all Company policies (including any policy regarding Internet use as may be set forth in the Company’s Employee Handbook) and applicable laws, including those relating to intellectual property, privacy, defamation (libel and slander) and unfair competition. You are reminded that all on-line, social media and e-mail activities, intentionally or not, are potentially public in nature. We must never act in a way that would bring liability, loss of credibility or embarrassment to the Company. Adhering to these guidelines with respect to computer use is very important, as violation may result in significant civil and even criminal penalties for both you and the Company.

XI.Intellectual Property

Each employee, officer and director has an obligation to protect the Company’s intellectual property. These “intellectual properties” may not be tangible like our buildings or equipment, but they are among the most valuable of the Company’s assets. Our patents, logos, brand, copyrights, software, know- how and trademarks are examples of the Company’s intellectual property. We protect all of our intellectual property rights — even those that are not patentable or protected by copyright or trademark laws — to the fullest extent permitted by law. In keeping with the Company’s high standards for quality and ethical conduct, each of us must protect the value of the intellectual property of the Company by protecting their confidentiality and safeguarding them from theft, infringement or misuse, including by using Company trademarks and brand resources properly and consistently. Furthermore, all employees, officers and directors shall maintain the secrecy of innovations for which the Company will seek or is seeking patent or trade secret protection. You must advise senior management or the Compliance Officer of infringements by others or if you are unsure about a proposed use of Company intellectual property or any other materials for public dissemination. In addition to the guidelines included in this Code, employees and officers are subject to the obligations provided by any proprietary information and inventions assignment agreements that they may enter into with the Company.

XII.Fair Dealing

The Company is committed to maintaining the highest legal and ethical standards in the conduct of its business. Meeting this commitment is the responsibility of the Company and each and every one of its employees, officers and directors. Each employee, officer and director should endeavor to deal fairly with the Company’s customers, vendors, suppliers, business partners, competitors and employees. No officer, director or employee should take unfair advantage of anyone through manipulation, concealment, abuse of privileged information, misrepresentation of material facts, or any unfair dealing practice.

XIII.Protection of Other Company Assets; Proprietary Information

Exhibit 14.1

You must endeavor to protect the Company’s assets and property and ensure their efficient use. Our assets include, among other things, our office equipment, technology and information. Theft, carelessness and waste have a direct impact on our profitability. You must use all assets and property of the Company for legitimate business purposes only. You must report any suspected incident of fraud or theft immediately to your supervisor or the Compliance Officer for investigation. If you are an officer or director you must report such fraud or theft to the Board or a committee of the Board.

To protect the security of Company information, the Company reserves the right to restrict personal use of e-mail and Internet services. Such restrictions include website restrictions, size and type of files (for example, photos, music or video), or the dissemination of spam messages. All software used on Company computers must be legal, licensed and in compliance with Company policies. Employees are prohibited from installing any non-compliant software without the authorization of the IT Department.

Your obligation to protect our assets includes the Company’s proprietary information. Proprietary information includes, but is not limited to, business, marketing and strategic plans, research and development strategies, customer and mailing lists, supplier, vendor and business partner names and pricing, records, salary information, intellectual property, information management system, any unpublished financial data and reports and any unique products, processes or information the Company has developed. Unauthorized use or distribution of this information violates this Code and may subject you to civil or criminal penalties.

XIV.Anti-Bribery and Anti-Corruption and Anti-Money Laundering; Political Contributions

The Company will not tolerate bribery or any form of corruption. Payments or promises to pay something of value to obtain or retain business or otherwise secure an improper advantage must never be made to a government official, employee or parties with whom the Company maintains a business and/or contractual relationship. The Company conducts its business in a manner consistent with foreign corrupt practices and/or any applicable governmental laws, rules and regulations. If you have any questions regarding this policy, you should contact the Compliance Officer.

A.Payments to Government Officials. The U.S. government has a number of laws and regulations regarding business gratuities that may be accepted by U.S. government personnel. The promise, offer or delivery to any official or employee of the U.S. government of a gift, favor or other gratuity on behalf of the Company, directly or indirectly, in violation of these rules would violate Company policy and could be a criminal offense. Foreign, state and local governments may have similar rules that you must also comply with. Employees, directors and officers may only transact business on behalf of the Company in foreign markets and with foreign government officials in accordance with the Company’s established policies regarding foreign corrupt practices and/or any applicable governmental laws, rules and regulations.

Exhibit 14.1

This policy is not intended to curtail your freedom to support political candidates and causes within legal limits, but care should be exercised so that no action by you is perceived as an attempt to influence government decisions in matters affecting the Company. Any personal contribution to any political candidate, party or organization must not be represented as a contribution from the Company, and you should not identify employment by the Company in connection with your individual political activities.

The Company prohibits facilitation payments, which are small value payments made to a government official, in order to secure or speed up the performance of a routine or expected governmental action to which the payer is entitled. All employees are expressly prohibited from offering, promising, accepting, giving, soliciting, receiving or authorizing, a bribe or facilitation payment.

B.Third-Party Risk. All employees must take reasonable precautions to ensure that all third parties they engage have solid qualifications, charge customary fees, have no apparent conflicts of interest, and are willing to sign a written contract that includes a statement that they will not make payments prohibited by law. Third parties include suppliers, agents, brokers, consultants, and other business partners. All employees should exercise due care in selecting such business partners to ensure they are reputable, honest, and qualified for their roles, and in monitoring their activity once selected. All employees must follow any mandatory due diligence procedures adopted by the Company in regards to third-party intermediaries.

C. Counterparty Risk. The Company requires the employees to conduct a reasonable level of due diligence on all counterparties and proposed transactions in order to detect risks associated with foreign corrupt practices and/or any applicable governmental laws, rules and regulations. Prior to beginning a relationship with any counterparties, such as vendors, suppliers or business partners, the Company will conduct due diligence checks to identify, among others, the potential involvement of (i) trade controls targets; (ii) embargoed and sanctioned territories; and (iii) any indication of illegal or other illicit activities. Prior to entering into any transactions with new or existing counterparties, the Company will screen the names of any guarantors, intermediaries, or banks involved in the proposed transaction(s) against the applicable trade control lists.

XV.Disclosure Obligations and Procedures

The Company’s policy is to release data of public importance, including reports to be filed with the SEC, at the earliest appropriate time consistent with the need to both maintain confidentiality of information before final decisions are made and to avoid endangering the Company’s business through disclosure of information potentially advantageous to competitors. All public statements, oral or written, must be accurate, with no material omissions. Information that could reasonably be expected to have an impact on the market for Company securities may be released only through the Company’s Authorized Spokespersons (as defined in the Company’s Disclosure Policy). All inquiries from financial analysts, media representatives, or financial consultants should also be directed to the Compliance Officer, the Public Relations Department or

Exhibit 14.1

the CFO. Financial information and results, including projections, forecasts, and forward-looking statements, should not be supplied in business proposals, presentations or advertising or presented to the press or released to the media without express prior approval and review by the CFO and the Public Relations Department. For further information on disclosure obligations and procedures, see the Company’s Disclosure Policy.

Social media, such as Twitter, Facebook and LinkedIn, brings opportunities to build conversations and communities, but also carries certain risks. All employees, officers and directors of the Company must therefore engage in social media conduct in a cautious and careful manner and only the Company’s Public Relations Department may represent the Company in social media. In addition, employees may not engage in social media postings that are inconsistent with the Company’s confidentiality policies. The use of any social network, blog or public website to post non-public information related to the Company is prohibited without the Company’s authorization.

XVI.Amendments and Waivers of this Code

From time to time, the Company may amend certain provisions of this Code. Waivers of this Code for executive officers and directors of the Company must be granted by the Audit Committee. Waivers of this Code for all other employees of the Company may be granted by an executive officer of the Company. Amendments to and waivers of this Code will be publicly disclosed as required by applicable laws and regulations.

XVII.Compliance with this Code

The Company takes this Code very seriously. You must understand this Code and take responsibility for seeking the advice of your supervisor or other appropriate officials of the Company if you need clarification on any point. Employees who have questions about this Code or wish to make an anonymous report of any suspected or actual violations of this Code are also encouraged to call the Company’s confidential compliance and ethics hotline at (800) 916-7037 ext.7736 or on the Internet at https://irdirect.net/SRFM/whistleblower_iframe/.

A.Reporting Violations. If you believe you have violated this Code or any applicable laws or regulations, you must report the violation so that the Company can take appropriate action. The fact that you reported the violation will be given consideration in determining appropriate disciplinary action, if any. In many cases, a prompt report of a violation can substantially reduce the adverse impact of a violation on all involved, on third parties, on the Company and on you. If you become aware that another employee, of whatever level of seniority, has, in all likelihood, violated this Code, including any law or regulation applicable to the Company’s businesses, you are under a duty to report that violation, in order that the Company can take steps to rectify the problem and prevent a recurrence. Violations may be reported to your supervisor, the Human Resources Department, Compliance Officer or the CFO, as appropriate. Such reports will be treated confidentially to the extent possible, and no person will be subject to retaliation for reporting a suspected violation in good faith. Employees are expected to cooperate in internal investigations of misconduct and the Company prohibits retaliation against individuals who cooperate with the investigation of any complaints. Any employee may

Exhibit 14.1

submit a good-faith concern regarding questionable accounting or auditing matters without fear of dismissal or retaliation of any kind.

B.Disciplinary Action. The Company intends to use every reasonable effort to prevent the occurrence of conduct not in compliance with this Code and other Company policies, including those outlined in the Company’s Employee Handbook, and to halt any such conduct that may occur as soon as reasonably possible after its discovery. Company employees and officers who violate this Code and other Company policies and procedures may be subject to disciplinary actions, which may include termination. In addition, disciplinary measures will apply to anyone who directs or approves infractions, or has knowledge of them and does not move promptly to correct them in accordance with Company policies. In addition, persons who violate the law during the course of their employment may be subject to criminal and civil penalties, as well as payment of civil damages to others.

The Board shall determine, or designate appropriate persons to determine, appropriate actions to be taken in the event of violations of this Code by the CEO or the Company’s senior financial officers. Such actions shall be reasonably designed to deter wrongdoing and to promote accountability for adherence to this Code and shall include written notices to the individuals involved that the Board has determined that there has been a violation, censure by the Board, demotion or re-assignment of the individual involved, suspension with or without pay or benefits (as determined by the Board) and termination of the individual’s employment. In determining what action is appropriate in a particular case, the Board or such designee shall take into account all relevant information, including the nature and severity of the violation, whether the violation appears to have been intentional or inadvertent, whether the individual in question has been advised prior to the violation as to the proper course of action and whether or not the individual in question had committed other violations in the past.

C.WhistleblowerStatutes. Nothing in this Code or any other Company policy is intended to prohibit you from reporting, in a confidential manner, possible violations of a federal law or regulation to any governmental agency or entity where the Company operates, including but not limited to the Securities and Exchange Commission, or making other disclosures that are protected under the whistleblower provisions of state or federal law or regulation or otherwise participate in an investigation or proceeding conducted by such agency or entity, or to recover any award offered by such agency or entity associated with such report. You do not need the prior authorization of the Company to make any such reports or disclosures and you are not required to notify the Company that you have made such reports or disclosures.

Description of Business [Abstract]

Description of Business

Note 1. Description of Business

Organization

Surf Air Mobility Inc. (the “Company”), a Delaware corporation, is building a regional air mobility ecosystem that will aim to sustainably connect the world’s communities. The Company intends to accelerate the adoption of green flying by developing, together with its commercial partners, hybrid-electric and fully-electric powertrain technology to upgrade existing fleets, and by creating a financing and services infrastructure to enable this transition on an industry-wide level.

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

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 New York Stock Exchange.

As the Internal Reorganization took place on July 21, 2023, the historical financial statements presented in this Quarterly Report on Form 10-Q 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.

Southern Acquisition

On July 27, 2023 (the “Acquisition Date”), immediately prior to the Company’s listing on the New York Stock Exchange 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 Southern Acquisition, Southern stockholders were to receive 16,250,000 shares of the Company's common stock, which was based on the aggregate merger consideration of $81.25 million at the $5.00 per share opening price on the first day of listing of the Company's common stock. In total, 16,249,963 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 Airways Corporation is a Delaware corporation that was founded on April 5, 2013, and together with its wholly owned subsidiaries Southern Airways Express, LLC, Southern Airways Pacific, LLC, Southern Airways Autos, LLC, and Multi-Aero Inc. is referred to hereafter collectively as “Southern.” 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 which operates a fleet of over 50 aircraft, including the Cessna Caravan, the Cessna Grand Caravan, the King Air Super 200, the Saab 340, 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.

Liquidity and Going Concern

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 Condensed Consolidated Balance Sheet as of September 30, 2023 and December 31, 2022. As discussed in Note 14, 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 beginning 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’s total outstanding federal excise tax liability including accrued penalties and interest of $7.0 million is included in accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheet as of September 30, 2023. 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 $1.9 million as of September 30, 2023. 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 September 30, 2023, the amount of property tax, interest and penalties related to the 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 September 30, 2023, 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 10, Financing Arrangements). The SAFE-T note is subordinate to the Company’s Convertible Note Purchase Agreement (see Note 10, 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 September 30, 2023.

In 2019, in connection with certain past due rental and maintenance payments under its aircraft leases totaling in aggregate approximately $5.0 million, which is accrued for at September 30, 2023 and December 31, 2022 as Other long-term liabilities on the Condensed Consolidated Balance Sheet, the Company entered into a payment plan pursuant to which all repayments of the past due amounts are deferred until such time as the Company receives at least $30.0 million in aggregate funds in connection with any capital contribution, at which time it is required to repay $1.0 million of such past due payments, with the eventual full repayment of the remaining amounts being required upon the receipt of at least $50.0 million in capital contributions. As of September 30, 2023, the Company has not made any payments under this payment plan.

The accompanying unaudited condensed 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 raise additional capital (or financing) to fund operating losses, refinance its current outstanding debt, maintain efficient aircraft utilization, primarily through the proper utilization of pilots and managing market shortages of maintenance personnel and critical aircraft components, sustain ongoing operations, attract and maintain customers, integrate, manage and grow recent acquisitions and new business initiatives, obtain and maintain relevant regulatory approvals, and measure and manage risks inherent to the business model.

In addition to the risks and uncertainties associated with the Company’s emerging and legacy business models, there continues to be a worldwide impact from the COVID-19 pandemic. The impact of COVID-19 has resulted in changes in consumer and business behavior, pandemic fears, market downturns, and restrictions on business and individual activities, which created significant volatility in global economy and has led to reduced economic activity particularly in the air travel industry. Due to enhanced virtual meeting and teleconferencing technology that has been adopted throughout the COVID-19 pandemic, more people are meeting over virtual meeting platforms than in person, which reduces the need for transportation. Specifically, COVID-19 related disruption in air travel has led to a decrease in membership sales, flight cancellations and significant operational volatility contributing to the Company defaulting on certain debt arrangements and amending the terms and conditions of certain debt arrangements, in order to meet liquidity needs (see Note 10, Financing Arrangements).

Prior to the quarter ended September 30, 2023, the Company has 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 quarter ended September 30, 2023, the Company received $8 million under a convertible note purchase agreement with Partners for Growth V, L.P. (“PFG”), $25 million through the Share Purchase Agreement with GEM Global Yield LLC SCS (“GEM”) and an entity affiliated with GEM that provides incremental financing (see Note 11, Share Purchase Agreement and GEM Purchase), and $4.5 million in advances under the Share Purchase Agreement with GEM (see Note 11, Share Purchase Agreement and GEM Purchase). On November 9, 2023, the Company filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission (the “SEC”) registering up to 300.0 million shares of the Company’s common stock, which represents the balance of the full amount of shares of common stock that the Company estimates could be issued and sold to GEM for advances under the Share Purchase Agreement, plus the amount of shares the Company estimates could be sold to GEM for $50 million under the Share Purchase Agreement.

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, 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, 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 hybrid-electric or fully-electric aircraft, or reducing funding of capital expenditures, which would 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 accompanying condensed 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.

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Interim Financial Information

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the interim financial statements do not include all of the information and footnotes required by U.S. GAAP for annual financial statements and should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2022 and the related notes, as included in the Company’s Registration Statement on Form S-1 and Form S-4 filed on July 25, 2023. The information herein reflects all material adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the results for the period presented. The results for the nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023.

Except for the policies discussed below, there have been no material changes to the Company’s significant accounting policies, during the nine months ended September 30, 2023 from those disclosed in the notes to the Company’s consolidated financial statements for the year ended December 31, 2022.

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements include the assets, liabilities, and operating results of the Company. All intercompany balances and transactions have been eliminated in consolidation.

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 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 the purchase price of an acquisition, whichever comes first, any subsequent adjustments are recorded in the Consolidated Statements of Operations.

Accounts Receivable, net

Accounts receivable primarily consist of amounts due from the United States Department of Transportation (“U.S. DOT”) in relation to certain air routes served by the Company under the Essential Air Service (“EAS”) program, amounts due from airline and non-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 September 30, 2023, and December 31, 2022. The Company has considered past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

Collateralized Borrowings

The Company has a revolving accounts receivable financing arrangement that allows the Company to borrow up to 90% of eligible accounts receivable due from the U.S. DOT, in relation to certain air routes served by the Company under the EAS program, up to a maximum unsettled amount of $5 million. 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 balance sheet 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 Condensed 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 Condensed Consolidated Statements of Operations.

Restricted Stock Unit Awards

The grant date fair value of restricted stock units (“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 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. 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. Provided that each founder continues to be employed by the Company, stock-based compensation expense is recognized over the derived service period, regardless of whether the stock price goals are achieved.

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 has one reporting unit. The Company tests goodwill for impairment annually, or more frequently if events or changes in circumstances indicate that the asset may be impaired.

The Company reviews goodwill for impairment utilizing either a qualitative assessment or a fair value test 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 fair value test, 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.

Fair value estimates are subject to change as a result of many factors, including changes in business plans, economic conditions, and the competitive environment, among others. Should actual cash flows and the Company’s future estimates vary adversely from previous estimates, the Company may be required to recognize goodwill impairment charges in future years.

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 the corresponding lease liabilities are reduced as lease payments are made.

Use of Estimates

The preparation of the condensed 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 condensed 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 condensed 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 condensed consolidated financial statements.

Recent Accounting Pronouncements

Adopted

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Topic (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities (deferred revenue) from acquired contracts using the revenue recognition guidance in ASC 606. Under this “ASC 606 approach”, the acquirer applies the revenue model as if it had originated the contracts. This is a departure from the current requirement to measure contract assets and contract liabilities at fair value. Under current practice, measuring deferred revenue at fair value typically results in a reduction to the deferred revenue balance the acquiree had recorded before the acquisition. The reduction causes the acquirer to recognize less revenue than the acquiree would have absent an acquisition. The amendments in this ASU are applied to business combinations occurring on or after the effective date of the amendments. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods for public entities and for fiscal years beginning after December 15, 2023, including interim periods for nonpublic entities. The Company early adopted ASU 2021-08 as of January 1, 2023, and has applied and will apply this guidance to acquisitions after the date of adoption.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). This new credit losses standard changes the accounting for credit losses for certain instruments. The new measurement approach is based on expected losses, commonly referred to as the current expected credit loss (“CECL”) model, which is utilized to estimate lifetime “expected credit losses” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses and applies to financial assets including loans, held-to-maturity debt securities, net investment in leases, and reinsurance and trade receivables, as well as certain off-balance sheet credit exposures, such as loan commitments. The standard also changes the impairment model for available-for-sale debt securities. In November 2019, the FASB issued ASU 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), which updated the effective date of this credit loss standard to fiscal years beginning after December 15, 2022 for nonpublic entities, including interim periods within those fiscal years. The Company adopted ASU 2016-13 as of January 1, 2023, and the guidance did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

In September 2022, the FASB issued ASU No. 2022-04, Liabilities – Disclosure of Supplier Finance Program Obligations (Topic 425). This ASU creates a disclosure framework by which buyers in a supplier finance program will be required to disclose significant qualitative and quantitative information to allow a user of financial statements to understand the program’s nature and potential magnitude. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASU 2022-04 as of January 1, 2023, and assessed that the guidance does not have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

Business Combination

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 16,250,000 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 New York Stock Exchange 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 $5.00 per share.

Subsequent to the issuance of shares of the Company’s common stock as purchase consideration, the Company repurchased 403,667 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 condensed consolidated financial statements from the date of acquisition, July 27, 2023, through September 30, 2023.

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

Cash	$	1,377
Accounts receivable, net		4,155
Prepaid expenses and other current assets		4,326
Property and equipment, net		37,372
Operating lease right-of-use assets		13,214
Finance lease right-of-use assets		303
Acquisition-related intangibles		28,150
Other assets		3,604
Total assets	$	92,501
Accounts payable		5,649
Accrued expenses and other current liabilities		10,405
Deferred revenue		7,329
Current maturities of long-term debt		2,923
Operating lease liabilities, current		3,624
Finance lease liabilities, current		147
Due to related parties, current		1,853
Long-term debt, net of current maturities		24,123
Operating lease liabilities, long term		6,836
Finance lease liabilities, long term		175
Due to related parties, long term		1,864
Deferred tax liability		3,750
Other noncurrent liabilities		37
Total liabilities	$	68,715
Fair value of net assets acquired		23,786
Goodwill		58,163
Total Purchase Consideration	$	81,949

The Company 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. The fair values are subject to adjustment for up to one year after the close of the transaction as additional information is obtained. The primary items pending are related to income tax matters. Any adjustments to the preliminary purchase price allocation identified during the measurement period will be recognized in the period in which the adjustments are determined.

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 is expected to be deductible for income tax purposes. Goodwill is not amortized to earnings, but instead will be reviewed for impairment at least annually, absent any interim indicators of impairment.

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

Asset	Fair Value		Weighted- Average Estimated Useful Life
EAS Route Contracts (1)	$	26,830	10 years
Corporate Tradename and Trademarks (2)		1,320	4 years
Total	$	28,150
(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 cost of sales and operating expenses.

The Condensed Consolidated Statement of Operations include the following revenue and net loss attributable to Southern from the date of acquisition, July 27, 2023, to September 30, 2023:

	July 27, 2023 through September 30, 2023
Revenue	$	15,336
Net Income	$	292

Unaudited Supplemental Pro Forma Information

Following are the supplemental condensed consolidated financial results of the Company and Southern on an unaudited pro forma basis, as if the Southern Acquisition had been consummated as of the beginning of the fiscal year 2022 (i.e., January 1, 2022):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2023			2022			2023			2022

Net loss	$	(50,751	)	$	(13,314	)	$	(77,542	)	$	(72,133	)

The unaudited pro forma financial information presented above has been calculated after adjusting the results of operations of the Company to reflect certain business combination effects, including the amortization of the acquired intangible assets, associated income tax impacts, incremental financing costs, and one-time acquisition-related costs incurred by the Company as though this business combination occurred as of January 1, 2022, the beginning of the Company’s 2022 fiscal year. The pro forma financial information is for informational purposes only and not indicative of the results of operations that would have been achieved if this business combination had taken place as of January 1, 2022, nor is it indicative of future results of operations.

Fair Value of Convertible Instruments

The Company has elected the fair value option for the convertible notes, 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 Condensed Consolidated Statements of Operations, except for change in 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.

On April 30, 2023, the Company amended the terms of the 2020 Convertible Note to extend the maturity date from May 1, 2023 to November 1, 2023. All other terms of the note remain the same, bearing compound interest at a rate of 6.25% per annum and a

monthly payment of $5 thousand. On June 27, 2023, the Company entered into a conditional exercise agreement for the 2020 Convertible Note to convert upon the merger of Surf Air into a subsidiary of the Company. The merger occurred on July 21, 2023, and all principal and accrued interest associated with the 2020 Convertible Note were converted into 1,383,342 convertible preferred shares, which were simultaneously cancelled and converted into 61,756 shares of the Company's common stock.

On June 1, 2023, the Company amended the terms of the 2017 Convertible Notes to extend the maturity date from May 31, 2023 to December 31, 2023. All other terms of the note remain the same. On June 27, 2023, the Company entered into a conditional exercise agreement for the 2017 Convertible Notes to convert upon the merger of Surf Air into a subsidiary of the Company. The merger occurred on July 21, 2023, and all principal and accrued interest associated with the 2017 Convertible Notes were converted into 31,845,296 convertible preferred shares, which were simultaneously cancelled and converted into 1,421,656 shares of the Company's common stock.

On June 21, 2023, the Company entered into a convertible note purchase agreement (the “Convertible Note Purchase Agreement”) with Partners for Growth V, L.P. (“PFG”) for a senior unsecured convertible promissory note for an aggregate principal amount of $8.0 million (the “PFG Investment”). The note bears interest at a rate of 9.75% and matures on December 31, 2024. All unpaid principal and interest balances may be converted into shares of the Company’s common stock, at the option of the holder, at a price equal to 120% of the initial listing price of the Company’s common stock.

On July 27, 2023, the Company received $8 million in funding, following satisfaction of all conditions precedent outlined under the Convertible Note Purchase Agreement. Based on the $5.00 per share opening price on the first day of listing of the Company’s common stock, the principal of the Convertible Note Purchase Agreement would be convertible into 1,333,333 shares of the Company’s common stock.

Fair Value of SAFE Notes

The Company’s Simple Agreements for Future Equity notes (“SAFE”) and Simple Agreement for Future Equity with Tokens (“SAFE-T”) are carried at fair value, with fair value determined using Level 3 inputs. The Company determined that the SAFE and SAFE-T instruments should be classified as liabilities based on evaluating the characteristics of the instruments, which contained both debt and equity-like features. The SAFE notes mature between May 2024 and June 2025. The SAFE-T instrument matured in July 2019. Subsequent changes in the fair value of the SAFE and SAFE-T notes are recorded in earnings as part of changes in fair value of financial instruments carried at fair value within the Condensed Consolidated Statements of Operations.

The decrease in the SAFE notes for the nine months ended September 30, 2023 is due to the conversion of the majority of the SAFEs into shares of the Company’s common stock, concurrent with the Company's listing on the New York Stock Exchange (see Note 12, Fair Value Measurements).

Share Purchase Agreement and GEM Purchase

Share Purchase Agreement [Abstract]

Share Purchase Agreement and GEM Purchase

Note 11. Share Purchase Agreement and GEM Purchase

Share Purchase Agreement

During 2020, the Company entered into a Share Purchase Agreement (“SPA”) with GEM Global Yield LLC SCS (“GEM”) and an entity affiliated with GEM to provide incremental financing in the event the Company completed a business combination transaction with a special purpose acquisition company (“SPAC”), IPO, or direct listing. Pursuant to the SPA, GEM is required to purchase shares of the Company’s common stock at a discount to the volume weighted average trading price up to a maximum aggregate purchase price of $200.0 million, and in return the Company agreed to pay a total commitment fee of $4.0 million (the “Commitment Fee”) payable in installments at the time of each purchase of shares of the Company’s common stock or no later than one year from the anniversary of a public listing transaction and issued a forward contract for GEM to purchase 0.75% of the Company’s fully-diluted shares of common stock outstanding upon completion of a public listing transaction at an exercise price of $0.01 per share.

On May 17, 2022, February 8, 2023, and September 18, 2023, the SPA was amended to increase the maximum aggregate shares of the Company’s common stock that may be required to be purchased by GEM to $400.0 million (the “Aggregate Limit”) and increase the Commitment Fee to GEM to 4,000,000 shares of the Company’s common stock. Pursuant to the amended and restated SPA, and subject to the satisfaction of certain conditions, the Company, will have the right from time to time at its option to direct GEM to purchase up to the Aggregate Limit of shares of the Company’s common stock over the term of the amended and restated SPA. Upon its public listing, the Company may request GEM to provide advances under the SPA in an aggregate amount of up to $100.0 million, provided that individual advances are not to exceed $25.0 million each, with the first advance not to exceed $7.5 million. Each advance will reduce the amount that the Company can request for future purchases under the SPA. On September 29, 2023, the Company received its first advance under the SPA in the amount of $4.5 million, on a total request of $7.5 million, with the remaining $3.0 million being

received on October 3, 2023. Concurrent with the receipt of funds, the Company issued 4,000,000 shares of its common stock to GEM in full satisfaction of the commitment fee. The Company has deposited 18,000,000 shares of common stock into an escrow account as of September 30, 2023, as required under the SPA, which is intended to be at least two times the number of shares contemplated to settle the advance upon the close of the pricing period for the advance. The number of shares to be transferred to GEM will be based on an average of the volume-weighted average trading price of the Company’s common stock over a period of fifteen trading days following the receipt of an advance, subject to a fifteen day extension in certain circumstances. This average price will be subject to a contractual discount of 10%. Additionally, contractual provisions within the SPA provide that in no event may GEM receive a share issuance that would raise their share ownership percentage above 10% of the Company. This provision may impact the Company’s ability to request additional advances or execute additional purchases under the SPA.

On June 15, 2023, July 21, 2023, and July 24, 2023, the SPA was further amended to modify the number of shares of the Company’s common stock to be issued to GEM at the time of a public listing transaction of the Company from an amount equal to 0.75% of the Company’s fully-diluted shares of common stock outstanding to a fixed 1,300,000 shares of the Company’s common stock. The amendments to the SPA also modified certain registration requirements whereby the Company was obligated to file a re-sale registration statement within 5 business days of the Company’s public listing. On July 27, 2023, concurrent with the Company’s direct listing, the Company issued 1,300,000 shares of the Company’s common stock to GEM in full satisfaction of this provision. Pursuant to GEM’s associated registration rights, the Company filed a re-sale registration statement, covering the 1,300,000 shares, on August 2, 2023, which was declared effective by the Securities and Exchange Commission (“SEC”) on September 28, 2023.

The Company has accounted for the shares issuance contracts under the SPA, as amended, as derivative financial instruments which are recorded at fair value within Other long-term liabilities on the Condensed Consolidated Balance Sheets. As of September 30, 2023 and December 31, 2022, the fair value of the GEM commitment was $5.0 million and $3.0 million, respectively. Changes in fair value were recorded in Changes in fair value of financial instruments carried at fair value, net on the Condensed Consolidated Statements of Operations.

GEM Purchase

On June 15, 2023, and amended on July 21, 2023, and July 24, 2023, the Company and GEM entered into a share purchase agreement (the “GEM Purchase”) whereby GEM would purchase 1,000,000 shares of the Company’s common stock for cash consideration of $25.0 million upon the successful public listing of the Company’s shares. Under the terms of the agreement, the Company is obligated to file a re-sale registration statement, covering the 1,000,000 shares issued, within 5 business days of the Company’s public listing. On July 27, 2023, concurrent with the Company’s direct listing, the Company received the $25.0 million cash consideration contemplated in the purchase agreement, in exchange for the issuance of 1,000,000 shares of the Company’s common stock. Pursuant to the associated registration rights, the Company filed a re-sale registration statement, covering the 1,000,000 shares, on August 2, 2023, which was declared effective by the SEC on September 28, 2023.

Fair Value Measurements

Note 12. Fair Value Measurements

The fair values of the convertible notes, SAFE instruments, preferred stock warrant liabilities, and derivative liability were based on the estimated values of the notes, SAFE instruments, warrants, and derivatives upon conversion including adjustments to the conversion rates, which were probability weighted associated with certain events, such as a sale of the Company or the Company 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.

Significant unobservable inputs used in the valuation models as of September 30, 2023 and December 31, 2022 were as follows:

	September 30, 2023	December 31, 2022
Public listing probability	100%	50%
Lack of marketability	—%	32%
Discount rates used in the sale scenario for debt instruments	—%	70%
Discount rates used in the public listing scenario	—%	20 - 30%
Probability weighted volatility	—%	147%

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 following tables summarize the Company’s financial liabilities that are measured at fair value on a recurring basis in the condensed consolidated financial statements (in thousands):

Preferred Share Warrants

Convertible Preferred Share Warrant Liability

There were no convertible preferred share warrants issued in the nine months ended September 30, 2023. The convertible preferred share warrants issued and outstanding as of December 31, 2022 were 805,823 shares of Class B-2 preferred warrants; 410,123 shares of Class B-3 preferred warrants; and 1,493,015 shares of Class B-4 preferred warrants. On July 21, 2023, as a condition of the Internal Reorganization, all preferred share warrants were converted into 120,935 warrants for the purchase of the Company’s common stock at a ratio of 22.4 Surf Air preferred warrants to 1 warrant for the purchase of the Company’s common stock. The exercise price for all warrants is $38.23 per share.

Warrants to purchase shares of convertible preferred stock were classified as Other long-term liabilities on the Condensed Consolidated Balance Sheets, as of December 31, 2022, and were subject to remeasurement to fair value at each balance sheet date with changes in fair value recorded in Changes in fair value of financial instruments carried at fair value through the date of the Internal Reorganization. As all converted warrants are for the purchase of common stock, and not preferred interests, the liability as of the date of the Internal Reorganization was reclassified to additional paid in capital.

Ordinary Share Warrants

Warrants were issued by Surf Air in connection with debt and equity capital raising transactions, as well as part of debt restructuring activities. The warrants were exercisable at any time, or from time to time, in whole or in part at any time on or prior to the expiration date, which was seven to ten years from the issuance date. The warrants terminated on the earlier of the expiration date or change in control upon the effectiveness of the Company’s registration statement or upon the closing of a deemed liquidation event. If there was no change in control, the warrants without a stated expiration date would never expire. On July 21, 2023, Surf Air merged into a subsidiary of the Company as part of an Internal Reorganization. The change in control resulted in all then outstanding ordinary share warrants being re-issued into warrants to purchase shares of the Company’s common stock.

Total outstanding ordinary share warrants issued by the Company were 0 and 4,614,651 as of September 30, 2023 and December 31, 2022, respectively. During 2023, the Company issued a total of 143,407 ordinary warrants due to the conversion of amounts due under the 2017 Convertible Notes (See Note 10, Financing Arrangements). During the nine months ended September 30, 2023, ordinary warrant holders exercised 4,758,058 ordinary warrants, with exercise prices ranging from $0.22 to $4.70 per share, on a combination of cash-based and cashless exercises. This resulted in the issuance of 4,707,562 shares of common stock for total proceeds of $128 thousand.

Commitments and Contingencies

Note 14. Commitments and Contingencies

Software License Agreements

On May 18, 2021, the Company executed two agreements with Palantir Technologies Inc. to license a suite of software for the term of seven years commencing on the effective date. The agreements identify two phases where Palantir provides services to customize the software: an Initial Term from May 18, 2021 through June 30, 2023 with a cost of $11.0 million and an Enterprise Term from July 1, 2023 to May 7, 2028 with a cost of $39.0 million, for a total cost of $50.0 million. As of September 30, 2023 and December 31, 2022, the Company capitalized $2.4 million and $2.0 million, respectively, related to the software that Palantir has provided to the Company.

Licensing, Exclusivity and Aircraft Purchase Arrangements

Textron Agreement

On September 15, 2022, the Company entered into agreements with Textron Aviation Inc. and one of its affiliates (collectively, “TAI”), for engineering services and licensing, sales and marketing, and aircraft purchases, which are only effective as of the first trading date of shares of the Company’s common stock on a national securities exchange (“TAI Effective Date”). The agreements became effective as of the Company’s direct listing on July 27, 2023.

The engineering services and licensing agreement provides, among other things, that TAI will provide the Company with certain services in furtherance of development of an electrified powertrain technology (the “SAM System”). Under this agreement, the Company agrees to meet certain development milestones by specified dates, including issuance of a supplemental type certificate by the FAA. Should the Company fail to meet certain development milestones, TAI has the right to terminate the collaboration agreement.

The licensing agreement grants the Company a nonexclusive license to certain technical information and intellectual property for the purpose of developing an electrified propulsion system for the Cessna Grand Caravan aircraft, and to assist in obtaining Supplemental Type Certificates (“STC”) from the Federal Aviation Administration (“FAA”), including any foreign validation by any other aviation authority, for electrified propulsion upfits/retrofits of the Cessna Grand Caravan aircraft. The licensing agreement provides for payment by the Company of license fees aggregating $60.0 million over a multi-year period, with an initial $5 million deposit being made as of September 30, 2023 and remaining payments of $7.5 million coming due in December 2023.

Under the sales and marketing agreement, the parties agreed to develop marketing, promotional and sales strategies for the specifically configured Cessna Grand Caravans and further agreed to: (a) include Cessna Grand Caravans fitted with the SAM system (the “SAM Aircraft”) in sales and marketing materials (print and digital) distributed to authorized dealers, (b) prominently display the SAM Aircraft on their respective websites and social media, (c) include representatives of the Company and TAI at trade show booths, (d) market the SAM Aircraft and conversions to SAM Aircraft to all owners of pre-owned Cessna Grand Caravans, and (e) not advertise or offer any third-party-developed electrified variants of the Cessna Grand Caravan. Certain technologies for aircraft propulsion are specifically carved out from TAI’s agreement to exclusively promote the SAM System for Cessna Grand Caravans. The sales and marketing agreement provides for payment by the Company of exclusivity fees aggregating $40.0 million, with certain amounts deferred such that the aggregate fee is payable over four years commencing on the earlier of the year after the Company obtains an STC for the SAM System on the Cessna Grand Caravan or the 5th anniversary of the TAI Effective Date. The Company’s obligation to pay exclusivity fees in any year may be offset, in whole or in part, based on the achievement of certain sales milestones of SAM Aircraft and Cessna Grand Caravans subsequently converted to a SAM System.

Under the aircraft purchase agreement, the Company may purchase from TAI 100 specifically configured Cessna Grand Caravans at prevailing market rates whereby the aggregate purchase price could be in excess of $300.0 million, with an option to purchase an additional 50 specifically configured Cessna Grand Caravans having an aggregate purchase price in excess of $150.0 million, over the course of 7 years. The final price to be paid by the Company will be dependent upon a number of factors, including the final specifications of such aircraft and any price escalations.

Jetstream Agreement

On October 10, 2022, the Company and Jetstream Aviation Capital, LLC (“Jetstream”) entered into an agreement (the “Jetstream Agreement”) that provides for a sale and/or assignment of purchase rights of aircraft from the Company to Jetstream and the leaseback of such aircraft from Jetstream to the Company within a maximum aggregate purchase amount of $450.0 million, including a $120.0 million total minimum usage obligation by the Company. The agreement may be terminated: (i) upon a termination notice by either party in the event that a material adverse change in the business of the other party is not resolved within 30 days of such notice; and (ii) as mutually agreed in writing by the parties. No transactions have been executed under this agreement as of September 30, 2023.

Business Combination Agreements

On May 17, 2022, the Company entered into a business combination agreement (the “Merger Agreement”) with Tuscan Holdings Corp II (“Tuscan”). On November 14, 2022, the Company and Tuscan mutually terminated the Merger Agreement. Pursuant to the terms of the mutually terminated Merger Agreement, the Company was obligated to issue to Tuscan 635,000 shares of the Company’s common stock or a combination of 600,000 shares of the Company’s common stock and $0.7 million in cash upon a triggering event, which was defined as a direct listing, IPO or a business combination with a SPAC.

On July 27, 2023, concurrent with the first day of listing of the Company’s common stock, the Company issued 635,000 shares of common stock to Tuscan in satisfaction of the terms of the mutually terminated Merger Agreement. Based on the $5.00 opening price

of the Company’s common stock, such shares have resulted in $3,175,000 of contract termination expense, included as part of other expense in the Company’s Condensed Consolidated Statement of Operations.

Guarantees

The Company indemnifies its officers and directors for certain events or occurrences arising as a result of the officer or director serving in such capacity. The term of the indemnification period is for the officer or director’s lifetime. The maximum potential future amount the Company could be required to pay under these indemnification agreements is unlimited. The Company believes its insurance would cover any liability that may arise from the acts of its officers and directors and as of September 30, 2023 the Company is not aware of any pending claims or liabilities.

The Company enters into indemnification provisions under agreements with other parties in the ordinary course of business, typically with business partners, contractors, customers, landlords and investors. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of its activities or, in some cases, as a result of the indemnified party’s activities under the agreement. These indemnification provisions sometimes include indemnifications relating to representations the Company has made with regards to intellectual property rights. These indemnification provisions generally survive termination of the underlying agreement. The maximum potential future amount the Company could be required to pay under these indemnification provisions is unlimited.

Legal Contingencies

In 2017, the Company acquired Rise U.S. Holdings, LLC (“Rise”). Prior to the close of the acquisition, Rise Alpha, LLC and Rise Management, LLC (both of which are wholly-owned subsidiaries of Rise and hereinafter referred to as the “Rise Parties”), were served with a petition for judgment by Menagerie Enterprises, Inc. (“Monarch Air”), relating to breach of contract for failure to pay Monarch Air pursuant to the terms and conditions of a flight services agreement with Monarch Air, which occurred prior to the Company’s acquisition of Rise. The Rise Parties filed numerous counterclaims against Monarch Air, including fraud, breach of contract and breach of fiduciary duty. Rise, a subsidiary of the Company, was named as a party in the lawsuit. During 2018 and 2019, certain summary judgements were granted in favor of Monarch Air.

On November 8, 2021, the Rise Parties entered into a final judgment in respect of litigation to finally resolve all claims raised by Monarch Air and the Rise Parties agreed to pay actual damages of $1.0 million, pre-judgment interest of $0.2 million, attorneys’ fees of $0.06 million and court costs of approximately $0.003 million. Since then, Monarch Air has been conducting post-judgment discovery. The full settlement had been accrued within Accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets by the Company as of September 30, 2023 and December 31, 2022.

The Company is also a party to various other claims and matters of litigation incidental to the normal course of its business, none of which were considered to have a potential material impact as of September 30, 2023.

Tax Commitment

On May 15, 2018, the Company received notice of a tax lien filing from the IRS for unpaid federal excise taxes for the quarterly periods beginning 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 (“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’s total outstanding federal excise tax liability, including accrued penalties and interest, is recorded in Accrued expenses and other current liabilities on the Condensed Consolidated Balance Sheets and is in the amount of $7.0 million and $5.8 million as of September 30, 2023 and December 31, 2022, respectively.

During 2018, the Company 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 $1.9 million and $1.7 million as of September 30, 2023 and December 31, 2022, respectively.

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Note 17. Stock-Based Compensation

2023 Equity Incentive Plan

Concurrent with the Company’s direct listing, the Company’s board of directors adopted the 2023 Equity Incentive Plan (the “2023 Plan”), to provide an additional means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons. A total of 7,500,000 shares of the Company’s common stock were initially authorized for issuance with respect to awards granted under the 2023 Plan. Shares subject to outstanding awards granted under the 2016 Plan that are not paid, delivered or exercised before they expire or are canceled or terminated will be available for award grants under the 2023 Plan. In addition, the shares authorized for grant will automatically increase on the first trading day in January of each year (commencing with 2024) by an amount equal to lesser of (1) 5.0% of the total number of our outstanding shares on the last trading day in December in the prior year, or (2) such lesser number as determined by our board of directors. Any shares subject to awards that are not paid, delivered or exercised before they expire or are canceled or terminated, fail to vest, as well as shares used to pay the purchase or exercise price of awards or related tax withholding obligations, will become available for other award grants under the 2023 Plan.

Awards under the 2023 Plan may be in the form of incentive or nonqualified stock options, stock appreciation rights, stock bonuses, restricted stock, stock units and other forms of awards including cash awards.

The Company issues shares of common stock upon the vesting and settlement of RSUs and upon the exercises of stock options under the 2023 Plan. The 2023 Plan is administered by the Company’s board of directors, or a duly authorized committee of the Company’s board of directors.

2016 Equity Incentive Plan

Prior to the Company’s direct listing, the Company granted stock options, RSUs, RSPAs, and RSGAs to its employees, as well as nonemployees (including directors and others who provide substantial services to the Company) under the Company’s 2016 Equity Incentive Plan (the “2016 Plan”). Concurrent with the Internal Reorganization, all rights under previously granted RSPAs and RSGAs were converted into shares of the Company’s common stock, with the Company retaining certain rights of repurchase with respect to unvested RSPAs to coincide with grant-date service-conditions. Additionally, based on the original terms of the underlying awards, all RSUs granted under the 2016 Plan fully vested as of the direct listing date.

No further stock awards will be granted under the 2016 Plan now that the 2023 Plan is effective; however, awards outstanding under the 2016 Plan will continue to be governed by their existing terms.

2023 Employee Stock Purchase Plan

In conjunction with the Company’s direct listing, the Company’s board of directors adopted, and the Company’s stockholders approved the Company’s 2023 employee stock purchase plan (the “ESPP”). The Company’s ESPP authorizes the issuance of 800,000 shares of the Company’s common stock under purchase rights granted to the Company’s employees or to the employees of any of its designated affiliates. The number of shares of the Company’s common stock reserved for issuance will automatically increase on January 1 of each year for a period of 10 years, beginning January 1, 2024, by the lesser of (i) 1% of the total number of shares of the Company’s common stock outstanding on December 31 of the immediately preceding year; and (ii) 800,000 shares, except before the date of any such increase, the Company’s board of directors may determine that such increase will be less than the amount set forth in clauses (i) and (ii).

As of September 30, 2023, there had been no offering period or purchase period under the ESPP, and no such period will begin unless and until determined by the administrator, which is the Company’s board of directors or a duly authorized committee of the Company’s board of directors.

Management Incentive Bonus Plan

In conjunction with the Southern Acquisition, the Company’s board of directors adopted the Southern Management Incentive Bonus Plan (the “Incentive Bonus Plan”). The Incentive Bonus Plan provides select employees, consultants and service providers of the Company who were direct or indirect shareholders of Southern an incentive to contribute fully to the Company’s business achievement goals and success. The Incentive Bonus plan will provide for two tranches of bonus pools, to be allocated to covered employees based on participation units, which vest upon each employee’s continued employment by the Company and the achievement of certain revenue targets. Payments of amounts due under the Incentive Bonus Plan may be made in cash or shares of the Company’s common stock, at the Company’s option. Any shares to be issued under the Incentive Bonus Plan are excluded from the Company’s common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders. Due to current expectations of revenue targets being achieved, the Company has recorded $6.7 million of stock based compensation expense related to the Incentive Bonus Plan during the three months

ended September 30, 2023. Such amounts are included as a portion of Accrued expenses and other current liabilities within the Company’s Condensed Consolidated Balance Sheet.

Stock Options

Prior to the Company’s direct listing, the Company granted stock options to its employees, as well as nonemployees (including directors and others who provide substantial services to the Company) under the 2016 Plan, and subsequent to its direct listing, may grant similar awards under the 2023 Plan.

A summary of share option activity for the nine months ended September 30, 2023 is set forth below:

	Number of Share Options Outstanding			Weighted Average Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)		Weighted Average Exercise Price Per Share
Outstanding at December 31, 2022		1,768,205			9.01	$	10,306	$	3.58
Granted		48,212			10.00		—		9.11

Exercisable at September 30, 2023		1,188,490			8.03		641		3.77

Stock based compensation expense attributable to these awards was $0.8 million and $2.4 million for the three and nine months ended September 30, 2023, respectively. This compares to $0.2 million and $0.5 million for the three and nine months ended September 30, 2022, respectively.

Restricted Stock Units

As of December 31, 2022, the Company had 220,424 RSUs outstanding under the 2016 Plan, which were unvested with a weighted average grant date fair value of $3.75 per RSU. With the Company’s direct listing, all vesting criteria for all awards was achieved, resulting in the issuance of 260,424 shares of common stock for total compensation expense of $0.8 million during the three and nine months ended September 30, 2023.

During the three months ended September 30, 2023, the Company issued 280,454 RSUs under the 2023 Plan to employees and non-employee directors, which vest upon the satisfaction of certain service periods. The fair value of these RSUs was determined based on the Company’s stock price the business day immediately preceding the grant date. The service period of these RSUs is satisfied over a range of 12 months to 2 years. The RSUs are excluded from common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders.

A summary of RSU activity for the nine months ended September 30, 2023 is set forth below:

	Number of RSUs			Weighted Average Grant Date Fair Value per RSU
RSUs at December 31, 2022		220,424		$	3.75
Granted and vested		280,454			8.80

Forfeited, cancelled, or expired		—			—
RSUs at September 30, 2023		240,454		$	8.80

Stock based compensation expense attributable to these awards was $1.8 million for both the three and nine months ended September 30, 2023 and 2023. This compares to $0 for both the three and nine months ended September 30, 2022.

Restricted Share Purchase Agreement

A summary of RSPA activity under the 2016 Plan for the nine months ended September 30, 2023 is set forth below:

	Number of RSPA			Weighted Average Grant Date Fair Value per RSPA
Unvested RSPAs at December 31, 2022		3,162,292		$	7.91
Granted		—			—
Vested		(2,696,004	)		8.56
Forfeited		—			—
Unvested RSPAs at September 30, 2023		466,288			4.12

On May 26, 2023, the Company approved the forgiveness of certain promissory notes associated with the issuance of RSPAs to executives and directors. The Company also provided cash bonuses to pay for interest and tax associated with the issuance of these shares in the amount of $0.1 million. The forgiveness of these promissory notes resulted in an immaterial additional stock based compensation expense as of September 30, 2023.

Prior to the Company’s direct listing, the Company’s board of directors determined that the remaining vesting requirements applicable to previously granted executive RSPA awards had been satisfied in connection with the Company’s direct listing. This resulted in the recognition of $21.8 million in previously unrecognized stock-based compensation expense during the three months ended September 30, 2023.

Stock-based compensation expense attributable to these awards was $22.8 million and $23.1 million for the three and nine months ended September 30, 2023, respectively. This compares to $0.3 million and $1.5 million for the three and nine months ended September 30, 2022, respectively.

Restricted Share Grant Agreement

As of December 31, 2022, there were 3,773,243 RSGA shares outstanding. As a result of the Internal Reorganization, on July 21, 2023, all outstanding RSGAs were converted and re-issued in the form of shares of the Company’s common stock, on a basis of 1 RSGA to 1 share of the Company’s common stock.

Stock based compensation expense attributable to these awards was $0 for the three and nine months ended September 30, 2023. This compares to $0 and $8.4 million for the three and nine months ended September 30, 2022, respectively.

Performance-Based Restricted Stock Units

In July 2023, the Company granted a total of 2,800,000 performance-based restricted stock units (“PRSUs”) to the Company’s founders (“Founder PRSUs”) under the 2023 Plan. The Founder PRSUs vest upon the satisfaction of a service condition and the achievement of certain stock price goals. The Founder PRSUs are excluded from the Company’s common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders.

The Founder PRSUs will vest only if (i) the per-share closing price of the Company’s common stock over a period of 10 consecutive trading days within five years from the date of the Company’s direct listing is greater than $10 per share and (ii) each founder’s employment with the Company or one of its subsidiaries continues through the date such stock price goal is achieved, subject to certain conditions.

The Company estimated the grant date fair value of the Founder PRSUs based on multiple stock price paths developed through the use of a Monte Carlo simulation model. A Monte Carlo simulation model also calculates a derived service period based on the expected time to achieve the defined stock price target, as described above. 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. An expiration term of 5 years (as defined in the grant agreements) was utilized. A volatility of 71.0 percent was determined, based on an established peer group over the maximum term to expiration. The weighted-average grant date fair

value of the Founders PRSUs was $2.28 per share. The Company will recognize total stock-based compensation expense of $6.4 million over the derived service period of 2.1 years as the founders satisfy the service-based vesting condition.

A summary of PRSU activity for the nine months ended September 30, 2023 is set forth below:

	Number of PRSUs		Weighted Average Grant Date Fair Value per PRSU
PRSUs at December 31, 2022		—	$	—
Granted		2,800,000		2.28
Shares issued		—		—
Forfeited, cancelled, or expired		—		—
PRSUs at September 30, 2023		2,800,000	$	2.28

Stock based compensation expense attributable to these awards was $0.5 million for both the three and nine months ended September 30, 2023. This compares to $0 for both the three and nine months ended September 30, 2022.

Income Taxes

Note 19. Income Taxes

The Company's provision for income taxes for the three and nine months ended September 30, 2023, was a ($3.6) million benefit resulting in an effective tax rate of 4.6% and 2.5%, respectively. The Company’s effective tax rate for both periods was lower than the federal statutory rate of 21% primarily due to the Company’s full U.S. federal and state valuation allowance. The Company's income tax provision for the three and nine months ended September 30, 2022, was immaterial. The Company’s 0% effective tax rate for both periods was lower than the federal statutory rate of 21% due to the Company’s full U.S. federal and state valuation allowance.

As a result of the Southern Acquisition, the Company recorded $3.7 million in acquired net deferred tax liabilities primarily related to the excess of book basis over tax basis of the acquired intangible assets. In recording the deferred tax liability, the Company recorded a partial release of the valuation allowance on the Company’s net deferred tax assets, resulting in a discrete tax benefit for federal and state income taxes of $2.7 million and $0.8 million, respectively.

The Company is subject to income tax examinations by the U.S. federal and state tax authorities. There were no ongoing income tax examinations as of September 30, 2023. In general, tax years 2011 and forward remain open to audit for U.S. federal and state income tax purposes.

Earnings Per Share [Abstract]

Net Loss per Share Applicable to Ordinary Shareholders, Basic and Diluted

Note 22. Net Loss per Share Applicable to Ordinary Shareholders, Basic and Diluted

The Company calculates basic and diluted net loss per share attributable to ordinary 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 ordinary shares. As outlined in “Internal Reorganization” in Note 1, Description of Business, the effects of conversions at a ratio of 22.4 Surf Air shares to 1 share of the Company’s common stock, have been applied to outstanding common shares and rights to receive common shares for all periods presented in calculating earnings per share and for presentation within the Condensed Consolidated Statement of Changes in Redeemable Convertible Preferred Shares and Shareholders’ Deficit.

The following table sets forth the computation of net loss per ordinary share (in thousands, except share data):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2023			2022			2023			2022

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Interim Financial Information

Interim Financial Information

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the interim financial statements do not include all of the information and footnotes required by U.S. GAAP for annual financial statements and should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2022 and the related notes, as included in the Company’s Registration Statement on Form S-1 and Form S-4 filed on July 25, 2023. The information herein reflects all material adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the results for the period presented. The results for the nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023.

Except for the policies discussed below, there have been no material changes to the Company’s significant accounting policies, during the nine months ended September 30, 2023 from those disclosed in the notes to the Company’s consolidated financial statements for the year ended December 31, 2022.

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The condensed consolidated financial statements include the assets, liabilities, and operating results of the Company. All intercompany balances and transactions have been eliminated in consolidation.

Business Combination

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 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 the purchase price of an acquisition, whichever comes first, any subsequent adjustments are recorded in the Consolidated Statements of Operations.

Accounts Receivable, net

Accounts Receivable, net

Accounts receivable primarily consist of amounts due from the United States Department of Transportation (“U.S. DOT”) in relation to certain air routes served by the Company under the Essential Air Service (“EAS”) program, amounts due from airline and non-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 September 30, 2023, and December 31, 2022. The Company has considered past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

Collateralized Borrowings

Collateralized Borrowings

The Company has a revolving accounts receivable financing arrangement that allows the Company to borrow up to 90% of eligible accounts receivable due from the U.S. DOT, in relation to certain air routes served by the Company under the EAS program, up to a maximum unsettled amount of $5 million. 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 balance sheet 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 Condensed 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 Condensed Consolidated Statements of Operations.

Restricted Stock Unit Awards

Restricted Stock Unit Awards

The grant date fair value of restricted stock units (“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 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. 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. Provided that each founder continues to be employed by the Company, stock-based compensation expense is recognized over the derived service period, regardless of whether the stock price goals are achieved.

Goodwill

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 has one reporting unit. The Company tests goodwill for impairment annually, or more frequently if events or changes in circumstances indicate that the asset may be impaired.

The Company reviews goodwill for impairment utilizing either a qualitative assessment or a fair value test 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 fair value test, 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.

Fair value estimates are subject to change as a result of many factors, including changes in business plans, economic conditions, and the competitive environment, among others. Should actual cash flows and the Company’s future estimates vary adversely from previous estimates, the Company may be required to recognize goodwill impairment charges in future years.

Finance Leases

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 the corresponding lease liabilities are reduced as lease payments are made.

Use of Estimates

Use of Estimates

The preparation of the condensed 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 condensed 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 condensed 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 condensed consolidated financial statements.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Adopted

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Topic (“ASU”) 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities (deferred revenue) from acquired contracts using the revenue recognition guidance in ASC 606. Under this “ASC 606 approach”, the acquirer applies the revenue model as if it had originated the contracts. This is a departure from the current requirement to measure contract assets and contract liabilities at fair value. Under current practice, measuring deferred revenue at fair value typically results in a reduction to the deferred revenue balance the acquiree had recorded before the acquisition. The reduction causes the acquirer to recognize less revenue than the acquiree would have absent an acquisition. The amendments in this ASU are applied to business combinations occurring on or after the effective date of the amendments. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods for public entities and for fiscal years beginning after December 15, 2023, including interim periods for nonpublic entities. The Company early adopted ASU 2021-08 as of January 1, 2023, and has applied and will apply this guidance to acquisitions after the date of adoption.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). This new credit losses standard changes the accounting for credit losses for certain instruments. The new measurement approach is based on expected losses, commonly referred to as the current expected credit loss (“CECL”) model, which is utilized to estimate lifetime “expected credit losses” and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in more timely recognition of credit losses and applies to financial assets including loans, held-to-maturity debt securities, net investment in leases, and reinsurance and trade receivables, as well as certain off-balance sheet credit exposures, such as loan commitments. The standard also changes the impairment model for available-for-sale debt securities. In November 2019, the FASB issued ASU 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842), which updated the effective date of this credit loss standard to fiscal years beginning after December 15, 2022 for nonpublic entities, including interim periods within those fiscal years. The Company adopted ASU 2016-13 as of January 1, 2023, and the guidance did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

In September 2022, the FASB issued ASU No. 2022-04, Liabilities – Disclosure of Supplier Finance Program Obligations (Topic 425). This ASU creates a disclosure framework by which buyers in a supplier finance program will be required to disclose significant qualitative and quantitative information to allow a user of financial statements to understand the program’s nature and potential magnitude. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASU 2022-04 as of January 1, 2023, and assessed that the guidance does not have a material impact on the Company’s condensed consolidated financial statements and related disclosures.
