Business Description

Note 1. Description of Business Organization Surf Air Mobility Inc. (the “Company”), a Delaware corporation, is a regional air mobility platform that aims to transform regional flying. The Company currently operates one of the largest commuter airlines in the United States by scheduled departures as well as an expanding on-demand charter marketplace for passengers in the U.S. and globally. The Company’s operations provide scale, distribution and real-world operating data to validate and, eventually, deploy the software and technology offerings it is currently developing to support the modernization of air operations and the adoption of next-generation aircraft. 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 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. The Company was incorporated in 2021 and became the ultimate parent of both Surf Air and Southern Airways Corporation (“Southern”) in July of 2023 following the Company’s public listing on the New York Stock Exchange (“NYSE”). Reverse Stock Split On August 16, 2024, the Company effected a seven-for-one reverse stock split for all shares of the Company’s common stock issued and outstanding. As a result of the reverse stock split, every seven shares of the Company’s old common stock were converted into one share of the Company’s new common stock. Fractional shares resulting from the reverse stock split were settled by cash payment. Options, and other like awards, to purchase the Company’s common stock were also adjusted in accordance with their terms to reflect the reverse stock split. Adjustments resulting from the reverse stock split have been retroactively reflected as of all periods presented herein. 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 Consolidated Balance Sheets as of December 31, 2025 and December 31, 2024. As discussed in Note 13, Commitments and Contingencies , on May 15, 2018, the Company received a notice of a tax lien filing from the Internal Revenue Service (“IRS”) for unpaid federal excise taxes for the quarterly periods from October 2016 through September 2017 in the amount of $ 1.9 million, including penalties and interest as of the date of the notice. The Company agreed to a payment plan (the “Installment Plan”) whereby the IRS would take no further action and remove such liens at the time such amounts have been paid. In 2019, the Company defaulted on the Installment Plan. Defaulting on the Installment Plan can result in the IRS nullifying such plan, placing the Company in default and taking collection action against the Company for any unpaid balance. The Company is currently in default of these obligations, with a total outstanding federal excise tax liability, including accrued penalties and interest, of $ 9.9 million included in accrued expenses and other current liabilities on the Company’s Consolidated Balance Sheet as of December 31, 2025 . 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 $ 0.9 million as of December 31, 2025. Additionally, Los Angeles County had previously imposed a tax lien on four of the Company’s aircraft due to the late filing of the Company’s 2022 property tax return. During the year ended December 31, 2025 , the Los Angeles County tax liens were released as the Company finalized remediation of the late filing, inclusive of the completion of county audits, and made payments of $ 1.0 million on all property taxes due to Los Angeles County that were underlying the prior aircraft liens. As of December 31, 2025, 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 9, Financing Arrangements ).…
