CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q (this “Quarterly Report”) contains certain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside of the control of Wheels Up Experience Inc. (“Wheels Up”, or “we”, “us”, or “our”), that could cause actual results to differ materially from the results discussed in the forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding the expectations, hopes, beliefs, intentions or strategies of Wheels Up regarding the future, including, without limitation, statements regarding: (i) the size, demands and growth potential of the markets for Wheels Up’s products and services and Wheels Up’s ability to serve those markets; (ii) the degree of market acceptance and adoption of Wheels Up’s products and services including member program changes; (iii) Wheels Up’s ability to develop innovative products and services and compete with other companies engaged in the private aviation industry; (iv) Wheels Up’s ability to attract and retain customers; (v) the impact of Wheels Up’s operational efficiency and cost reduction efforts on its business and results of operations, including the timing and magnitude of such expected reductions and any associated expenses and impact of the new member operations center; (vi) Wheels Up’s ability to maintain cost discipline and achieve positive Adjusted EBITDA (as defined herein) pursuant to the schedule that it has announced; (vii) Wheels Up’s liquidity, future cash flows, acquisition activities, measures intended to increase Wheels Up’s operational efficiency and certain restrictions related to our debt obligations; and (viii) general economic and geopolitical conditions, including due to fluctuations in interest rates, inflation, foreign currencies, consumer and business spending decisions, and general levels of economic activity. In addition, any statements that refer to projections, forecasts, or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “strive,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that statement is not forward-looking. These forward-looking statements are subject to a number of risks, uncertainties and assumptions that could cause actual events and results to differ materially from those contained in such forward-looking statements, including those described in our Annual Report on Form 10-K for the year ended December 31, 2022 under Part I, Item 1A — “Risk Factors,” in this Quarterly Report under Part I, Item 2 — “Management’s Discussion and Analysis of Operations” and Part II, Item 1A — “Risk Factors,” and elsewhere in this Quarterly Report. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. You are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made, and Wheels Up undertakes no obligation to update or revise the forward-looking statements, whether as a result of new information, changes in expectations, future events or otherwise. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Except as required by law, we do not intend to update any of these forward-looking statements after the date of this Quarterly Report or to conform these statements to actual results or revised expectations.

Basis of Presentation
The unaudited interim condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the financial information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of the Company’s management, the unaudited condensed consolidated financial statements include all adjustments necessary for the fair presentation of the Company’s balance sheet as of March 31, 2023, and its results of operations, including its comprehensive loss, stockholders' equity and its cash flows for the three months ended March 31, 2023 and 2022. All adjustments are of a normal recurring nature. The results for the three months ended March 31, 2023 are not necessarily indicative of the results to be expected for any subsequent quarter or for the fiscal year ending December 31, 2023.
These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2023.
Principles of Consolidation
The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. We consolidate Wheels Up Partners MIP LLC (“MIP LLC”) and record the profits interests held in MIP LLC that Wheels Up does not own as non-controlling interests (see Note 12). All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates
Preparing the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect 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 revenues and expenses during the reporting period. Actual results could differ from those estimates due to risks and uncertainties. The most significant estimates include, but are not limited to, the useful lives and residual values of purchased aircraft, the fair value of financial assets and liabilities, acquired intangible assets, goodwill, contingent consideration and other assets and liabilities, sales and use tax, the estimated life of member relationships, the
8

determination of the allowance for credit losses, impairment assessments, the determination of the valuation allowance for deferred tax assets and the incremental borrowing rate for leases.
Foreign Currency Translation Adjustments
Assets and liabilities of foreign subsidiaries, where the functional currency is not the United States (“U.S.”) dollar, have been translated at period-end exchange rates and profit and loss accounts have been translated using weighted-average exchange rates. Adjustments resulting from currency translation have been recorded in the equity section of the condensed consolidated balance sheets and the condensed consolidated statements of other comprehensive loss as a cumulative translation adjustment.
Adopted Accounting Pronouncements and Accounting Pronouncements Note Yet Effective
There have been no recent accounting pronouncements, changes in accounting pronouncements or recently adopted accounting guidance during the three months ended March 31, 2023 that are of significance or potential significance to us.

Alante Air Charter, LLC Acquisition
On February 3, 2022, we acquired all of the outstanding equity of Alante Air Charter, LLC (“Alante Air”) for a total purchase price of $15.5 million in cash. Alante Air added 12 Light jets to our controlled fleet and expands our presence in the Western U.S. Acquisition-related costs for Alante Air of $0.5 million were included in general and administrative expense in the condensed consolidated statements of operations for the three months ended March 31, 2022. The acquisition of Alante Air was determined to be a business combination.
We have allocated the purchase price for Alante Air to its individual assets and liabilities assumed. As of the date of acquisition, the total purchase price allocated to the Alante Air assets acquired and liabilities assumed according to their estimated fair values were as follows (in thousands):

Goodwill represents the excess of the purchase price over the fair values of the acquired net tangible assets. The allocated value of goodwill primarily relates to anticipated synergies and economies of scale by combining the use of Alante Air’s aircraft and existing business processes with our other acquisitions. The acquired goodwill is deductible for tax purposes.
Air Partner plc Acquisition
On April 1, 2022, we acquired all of the outstanding equity of Air Partner plc (“Air Partner”) for a total purchase price of $108.2 million in cash. Air Partner is a United Kingdom-based international aviation services group that provides us with operations in 18 locations across four continents. Acquisition-related costs for Air Partner included in general and administrative expense in the condensed consolidated statements of operations for the three months ended March 31, 2022 were immaterial.

Net assets acquired | $ | 108,194 |

Current assets of Air Partner included $18.0 million of cash and $16.6 million of accounts receivable.
The allocated value of goodwill primarily relates to anticipated synergies and economies of scale by combining the use of Air Partner’s existing business processes with our platform to expand on an international basis. The acquired goodwill is not deductible for tax purposes.
The amounts allocated to acquired intangible assets and their associated weighted-average amortization periods, which were determined based on the period the assets are expected to contribute directly or indirectly to our cash flows, consist of the following:

| Amount (In thousands) |  | Weighted-Average Amortization Period (Years)
Customer relationships | $ | 16,521 |  |  | 5.7

The intangible asset fair value measurements are primarily based on significant inputs that are not observable in the market which represent a Level 3 measurement (see Note 8). The valuation method used for the Air Partner intangible assets was the income approach.

2022-1 Equipment Note Financing
On October 14, 2022, Wheels Up Partners LLC, our indirect subsidiary (“WUP LLC”), issued $270.0 million aggregate principal amount of 12% fixed rate equipment notes (collectively, the “Equipment Notes”) using an EETC (enhanced equipment trust certificate) loan structure. The Equipment Notes were issued for net proceeds (before transaction-related expense) of $259.2 million. The final expected distribution date of the Equipment Notes varies from July 15, 2025 to October 15, 2029, unless redeemed earlier by WUP LLC. The Equipment Notes bear interest at the rate of 12% per annum with annual amortization of principal amount equal to 10% per annum and balloon payments due at each maturity date. The Equipment Notes are secured by first-priority liens on 134 of the Company’s owned aircraft fleet and by liens on certain intellectual property assets of the Company and certain of its subsidiaries.
The Equipment Notes were sold pursuant to a Note Purchase Agreement, dated as of October 14, 2022 (the “Note Purchase Agreement”), and issued under separate Trust Indentures and Mortgages, dated as of October 14, 2022 (each, an “Indenture” and collectively, the “Indentures”). The Note Purchase Agreement and the Indentures and related guarantees contain certain covenants, including a liquidity covenant that requires the Company to maintain minimum liquidity of $125 million, a covenant that limits the maximum loan to appraised value ratio of all aircraft financed, subject to certain cure rights of the Company, and restrictive covenants that provide limitations under certain circumstances on, among other things: (i) certain acquisitions, mergers or disposals of its assets; (ii) making certain investments or entering into certain transactions with affiliates; (iii) prepaying, redeeming or repurchasing the Equipment Notes, subject to certain exceptions; and (iv) paying dividends and making certain other specified restricted payments. Each Indenture contains customary events of default for Equipment Notes of this type, including cross-default provisions among the Equipment Notes. WUP LLC’s obligations under the Equipment Notes are guaranteed by the Company and certain of its subsidiaries. WUP LLC is also obligated to cause additional subsidiaries and affiliates of WUP LLC to become guarantors under certain circumstances. The Equipment Notes issued with respect to each aircraft are cross-collateralized by the other aircraft for which Equipment Notes were
16

issued under the Indentures. The maturity of the Equipment Notes may be accelerated upon the occurrence of certain events of default under the Note Purchase Agreement and each Indenture and the related guarantees. As of March 31, 2023, we were in compliance with the covenants under the Note Purchase Agreement and each Indenture and the related guarantees.
As of March 31, 2023, the carrying value of the aircraft that are subject to first-priority liens under the Equipment Notes was $323.4 million.
Interest and principal payments on the Equipment Notes are payable quarterly on each January 15, April 15, July 15 and October 15, which began on January 15, 2023. Amortization expense for debt discounts and deferred financing costs of $0.9 million was recorded in interest expense in the condensed consolidated statement of operations for the three months ended March 31, 2023.
8. FAIR VALUE MEASUREMENTS
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability, an exit price, in an orderly transaction between unaffiliated willing market participants on the measurement date under current market conditions. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available and activity in the markets used to measure fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

Level 1 - | Quoted prices, unadjusted, in active markets for identical assets or liabilities that can be accessed at the measurement date.
Level 2 - | Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3 - | Unobservable inputs developed using our own estimates and assumptions, which reflect those that market participants would use in pricing the asset or liability.

17

Financial instruments that are measured at fair value on a recurring basis and their corresponding placement in the fair value hierarchy consisted of the following (in thousands):

| March 31, 2023
| Level 1 |  | Level 2 |  | Level 3 |  | Fair Value
Assets: |  |  |  |  |  |  |
Money market funds | $ | 268,940 |  |  | $ | — |  |  | $ | — |  |  | 268,940 |

Total liabilities | $ | 479 |  |  | $ | 270,272 |  |  | $ | — |  |  | $ | 270,751 |

The carrying amount of cash equivalents approximates fair value and is classified within Level 1, because we determined the fair value through quoted market prices.
The estimated fair value of the Equipment Notes is categorized as a Level 3 valuation. We considered the relatively short time period between the issuance of the Equipment Notes and the measurement date of March 31, 2023, as well as the estimated fair value of aircraft subject to first priority liens under the Equipment Notes to determine the fair value of the Equipment Notes as of March 31, 2023.
The warrants were accounted for as a liability in accordance with Accounting Standards Codification 815-40 (see Note 11). The warrant liability was measured at fair value upon assumption and on a recurring basis, with changes in fair value presented in the condensed consolidated statements of operations. As of March 31, 2023 and December 31, 2022, we used Level 1 inputs for the Public Warrants (as defined below) and Level 2 inputs for the Private Warrants (as defined below). We valued the Private Warrants by applying the valuation technique of a Monte Carlo simulation model to reflect the redemption conditions. The Private Warrants are substantially similar to the Public Warrants, but are not directly traded or quoted on an active trading market.

The following table presents the changes in the fair value of the warrant liability (in thousands):

| Public Warrants |  | Private Warrants |  | Total Warrant Liability
Fair value as of December 31, 2022 | $ | 479 |  |  | $ | 272 |  |  | $ | 751 |
Change in fair value of warrant liability | (80) |  |  | (45) |  |  | (125) |
Fair value as of March 31, 2023 | $ | 399 |  |  | $ | 227 |  |  | $ | 626 |

9. LEASES
Leases primarily pertain to certain controlled aircraft, corporate headquarters and operational facilities, including aircraft hangars, which are all accounted for as operating leases. We sublease an aircraft hangar at Cincinnati/Northern Kentucky International Airport from Delta. Certain of these operating leases have renewal options to further extend for additional time periods at our discretion.
Our leases do not contain residual value guarantees, covenants or other associated restrictions. We have certain variable lease agreements with aircraft owners that contain payment terms based on an hourly lease rate multiplied by the number of flight hours during a month. Variable lease payments are not included in the right-of-use asset and lease liability balances but rather are expensed as incurred.

10. STOCKHOLDERS’ EQUITY AND EQUITY-BASED COMPENSATION
Pursuant to the Wheels Up Experience Inc. certificate of incorporation, we are authorized to issue 2,500,000,000 shares of Class A common stock, par value of $0.0001 per share, and 25,000,000 shares of preferred stock, par value $0.0001 per share. Holders of Class A common stock are entitled to one vote per share.
As of March 31, 2023, we have nine equity-based compensation plans that were approved by the board of directors of WUP prior to the Business Combination (as defined below), which collectively constitute the “WUP Management Incentive Plan”, and the Wheels Up Partners Holdings LLC Option Plan, which is the “WUP Option Plan.” Following the consummation of the Business Combination (as defined below), no new grants can be made under the WUP Management Incentive Plan or WUP Option Plan.
In connection with the Business Combination (as defined below), the board of directors (the “Board”) and stockholders of Wheels Up adopted the Wheels Up Experience Inc. 2021 Long-Term Incentive Plan (the “2021 LTIP”), for employees, consultants and other qualified persons.
On June 30, 2022, the Board adopted the Wheels Up Experience Inc. 2022 Inducement Grant Plan (the “2022 Inducement Plan”) to be used for a one-time employment inducement grant for our Chief Financial Officer, Todd Smith, pursuant to New York Stock Exchange Rule 303A.08. The maximum number of awards that could be granted under the 2022 Inducement Plan were 2,051,282 shares of Class A common stock, which were all granted in the form of restricted stock units to Mr. Smith on July 1, 2022. Restricted stock unit awards granted under the 2022 Inducement Grant Plan contain generally the same terms as other restricted stock unit awards granted under the 2021 LTIP during the fiscal year ended December 31, 2022.
WUP Management Incentive Plan
WUP Profits Interests
As of March 31, 2023, an aggregate of 31.3 million WUP profits interests have been authorized and issued under the WUP Management Incentive Plan. Vested WUP profits interests are eligible to be exchanged into shares
20

of Class A common stock. Amounts of WUP profits interests reported in the tables below represent the maximum number of WUP profits interests outstanding or that could be realized upon vesting and immediately exchanged for the maximum number of shares of Class A common stock. The actual number of shares of Class A common stock received upon exchange of such WUP profits interests will depend on the trading price per share of Class A common stock at the time of such exchange.
The following table summarizes the WUP profits interests activity under the WUP management incentive plan as of March 31, 2023:

Non-vested RSUs as of March 31, 2023 | 27,822 |  |  | $ | 1.87 |

(1) RSU awards granted under the 2022 Inducement Grant Plan contain generally the same terms as other RSU awards granted under the 2021 LTIP during the fiscal year ended December 31, 2022. The number of RSUs and weighted-average grant date fair value include 2,051,282 RSUs granted under the 2022 Inducement Grant Plan in July 2022, of which 683,760 RSUs had vested as of January 1, 2023 and the remaining 1,367,522 RSUs are scheduled to vest in equal installments on December 30, 2023 and December 30, 2024, subject to continued service through each such vesting date.
(2) RSU awards granted during the three months ended of March 31, 2023 are liability classified because such awards are contingent on receipt of approval by the Company’s stockholders of the Amended and Restated Wheels Up Experience Inc. 2021 Long-Term Incentive Plan (the "Amended and Restated 2021 LTIP”) at the Company’s 2023 annual meeting of stockholders (the “2023 Annual Meeting”). If the Company’s stockholders do not approve the Amended and Restated 2021 LTIP at the 2023 Annual Meeting, the Compensation Committee of the Board will settle such awards in cash upon vesting based on the fair market value per share of Class A common stock on the applicable vesting date.
The total unrecognized compensation cost related to non-vested RSUs was $42.7 million as of March 31, 2023 and is expected to be recognized over a weighted-average period of 1.4 years. The total fair value for RSUs that vested was approximated $8.4 million for the three months ended March 31, 2023.
Performance-Based Restricted Stock Units (“PSUs”)
Under the terms of the non-vested PSUs granted to certain employees, upon the achievement of certain pre-determined performance objectives, each PSU may settle into shares of our Class A common stock. The PSUs will vest, if at all, upon the actual achievement of the related performance objective, subject to specified change of control exceptions.
The following table summarizes the activity under the 2021 LTIP related to PSUs as of March 31, 2023:

| Number of PSUs |  | Weighted-Average Grant Date Fair Value
| (in thousands) |  |
Non-vested PSUs as of January 1, 2023 | 957 |  |  | $ | 2.17 |

Forfeited | — |  |  | — |
Non-vested PSUs as of March 31, 2023(2) | 2,086 |  |  | $ | 1.22 |

(1) PSU awards granted during the three months ended March 31, 2023 are liability classified because such awards are contingent on receipt of approval by the Company’s stockholders of the Amended and Restated 2021 LTIP at the 2023 Annual Meeting. If the Company’s stockholders do not approve the Amended and Restated 2021 LTIP at the 2023 Annual Meeting, the Compensation Committee of the Board will settle such awards in cash upon vesting based on the fair market value per share of Class A common stock on the applicable vesting date.
(2) Non-vested PSUs reflected in the table above include approximately 0.6 million of the PSUs reflected in this table may settle into shares of our Class A common stock equal to 0-120% of the PSUs and 1.3 million PSUs that may settle into shares of Class A common stock equal to 0-200% of the PSUs, in each case based on the level of performance.
Compensation expense associated with PSUs is recognized over the vesting period of the awards that are ultimately expected to vest when the achievement of the related performance objectives becomes probable. Total unrecognized compensation cost related to non-vested PSUs was $2.5 million as of March 31, 2023. As of
23

March 31, 2023, the achievement of the performance objectives associated with unvested awards was deemed not probable of being achieved and, accordingly, no compensation cost has been recognized. Compensation cost recognized during the three months ended March 31, 2023 associated with PSUs which vested during the period was $0.1 million.
RSUs Subject to Market-Based Vesting Conditions (“Market-Based RSUs”)
Under the terms of the non-vested Market-Based RSUs granted to certain employees each Market-Based RSU may settle into shares of our Class A common stock. The Market-Based RSUs will vest, if at all, based on the closing trading price per share of our Class A common stock over any 30 consecutive trading day-period that occurs prior to the end date specified in the underlying award agreement, subject to continued service through each such vesting date.
The grant-date fair value of outstanding Market-Based RSUs, using a Monte Carlo simulation model, was $0.3 million. The derived service period for such Market-Based RSUs began on June 8, 2022 with a weighted average period of 3.8 years. Based on the Class A common stock trading price, the market conditions for the outstanding Market-Based RSUs were not met, and no shares vested as of March 31, 2023. The total unrecognized compensation cost related to such Market-Based RSUs was $0.2 million as of March 31, 2023 and is expected to be recognized over 3.0 years.

Earnout Shares
On July 13, 2021 (the “Closing Date”), we consummated the transactions contained in the Agreement and Plan of Merger with Aspirational Consumer Lifestyle Corp. (“Aspirational”), a blank check company, dated as of February 1, 2021, as amended on May 6, 2021 (the “Business Combination”). As part of the Business Combination, existing holders of WUP equity, including certain holders of WUP profits interests and restricted interests, but excluding holders of WUP stock options, have the right to receive up to an aggregate of 9 million additional shares of our Class A common stock in three equal tranches, which are issuable upon the achievement of share price thresholds of $12.50, $15.00 and $17.50 for any 20 trading days within a period of 30 consecutive trading days within five years of the Closing Date, respectively (the “Earnout Shares”). Earnout Shares are not attributable to any equity compensation plan.
Earnout Shares that are attributable to WUP profits interests and restricted interests require continued employment as of the date on which each of the Earnout Share market conditions are met. There have been no forfeitures of Earnout Shares as of March 31, 2023.
The grant-date fair value of the Earnout Shares attributable to the holders of WUP profits interests and restricted interests, using a Monte Carlo simulation model, was $57.9 million. The derived service period began on the Closing Date and is a weighted-average period of 1.7 years.
Based on the Class A common stock trading price, the market conditions were not met, and no Earnout Shares vested as of March 31, 2023.

Prior to the Business Combination, Aspirational issued 7,991,544 public warrants (“Public Warrants”) and 4,529,950 private warrants (“Private Warrants”). On the Closing Date, Wheels Up assumed the warrants. Each
25

whole warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share. The Public Warrants and Private Warrants became exercisable on September 25, 2021, which was 12 months from the closing of the Aspirational initial public offering, and expire on July 13, 2026 or earlier upon redemption or liquidation.
In connection with the Business Combination, we filed a Registration Statement on Form S-1 that was declared effective by the SEC on August 24, 2021, as amended by Post-Effective Amendment No. 1 thereto that was declared effective by the SEC on March 21, 2022, as further amended by Post-Effective Amendment No. 2 to Form S-1 on Form S-3 filed with the SEC on July 20, 2022, and as further amended by Post-Effective Amendment No. 3 to Form S-1 on Form S-3 that was declared effective by the SEC on August 10, 2022 (collectively, the “Selling Stockholder Registration Statement”). The Selling Stockholder Registration Statement relates to the issuance of an aggregate of 12,521,494 shares of Class A common stock underlying the Public Warrants and Private Warrants. As of March 31, 2023, there have not been any warrants exercised and 12,521,494 remain outstanding.
12. NON-CONTROLLING INTERESTS
MIP LLC is a single purpose entity formed for the purpose of administering and effectuating the award of WUP profits interests to employees, consultants and other qualified persons. Wheels Up is the sole managing member of MIP LLC and, as a result, consolidates the financial results of MIP LLC. We record non-controlling interests representing the ownership interest in MIP LLC held by other members of MIP LLC. In connection with the Business Combination, the Seventh Amended and Restated LLC Agreement of WUP was adopted, allowing members of MIP LLC, subject to certain restrictions, to exchange their vested WUP profits interests for cash or a corresponding number of shares of Class A common stock, at the option of Wheels Up, based on the value of such WUP profits interests relative to their applicable participation threshold.
The decision of whether to exchange WUP profits interests for cash or Class A common stock is made solely at the discretion of Wheels Up. Accordingly, the WUP profits interests held by MIP LLC are treated as permanent equity and changes in the ownership interest of MIP LLC are accounted for as equity transactions. Future exchanges of WUP profits interests, if settled in Class A common stock at the discretion of Wheels Up, will reduce the amount recorded as non-controlling interests and increase additional paid-in-capital on the condensed consolidated balance sheets.
The calculation of non-controlling interests was as follows:

| March 31, 2023 |  | December 31, 2022
Number of WUP common units held by Wheels Up(1) | 251,613,698 |  |  | 100.0 | % |  | 249,338,569 |  |  | 100.0 | %
Number of vested WUP profits interests attributable to non-controlling interests(2) | — | % |  | — | % |  | — |  |  | — | %
Total WUP common units and vested WUP profits interests outstanding | 251,613,698 |  |  | 100.0 | % |  | 249,338,569 |  |  | 100.0 | %

(1) WUP common units represent an equivalent ownership of Class A common stock outstanding.
(2) Based on the closing price of Class A common stock on the last trading day of the period covered by this Quarterly Report, there would be no WUP common units issuable upon conversion of vested and unvested WUP profits interests outstanding as of March 31, 2023.
Weighted-average ownership percentages are used to allocate net loss to Wheels Up and the non-controlling interest holders. The non-controlling interests weighted-average ownership percentage was 0.0% and 0.4% for the three months ended March 31, 2023 and March 31, 2022, respectively.

13. COMMITMENTS AND CONTINGENCIES
Legal Proceedings
We are party to various legal actions arising in the normal course of business. While we do not expect that the ultimate resolution of any of these pending actions will have a material effect on our consolidated results of operations, financial position, or cash flows, litigation is subject to inherent uncertainties. As such, there can be no assurance that any pending legal action, which we believe to be immaterial as of March 31, 2023, does not become material in the future.
Sales and Use Tax Liability
We regularly provide services to members in various states within the continental U.S., which may create sales and use tax nexus via temporary presence, potentially requiring the payment of these taxes. We determined that there is uncertainty as to what constitutes nexus in respective states for a state to levy taxes, fees and surcharges relating to our activity. As of March 31, 2023 and December 31, 2022, we estimate the potential exposure to such tax liability was $10.5 million and $10.4 million, respectively, the expense for which was included in accrued expenses on the condensed consolidated balance sheets and cost of revenue in the condensed consolidated statements of operations as of and for the applicable periods presented.
14. RELATED PARTIES
We engage in transactions with certain stockholders who are also members, ambassadors or customers. Such transactions primarily relate to their membership in the Wheels Up program, flights and flight-related services.
We incurred expenses of $0.6 million and $0.3 million for the three months ended March 31, 2023 and 2022, respectively, from transactions related to a commercial cooperation agreement with our stockholder Delta. As of March 31, 2023 and December 31, 2022, $2.9 million and $2.4 million, respectively, were included in Accrued expenses on the condensed consolidated balance sheets related to transactions associated with the commercial cooperation agreement.
Other transactions with related parties during the three months ended March 31, 2023 and 2022 were immaterial individually and in the aggregate for financial reporting purposes.
15. RESTRUCTURING AND RELATED CHARGES
On March 1, 2023, we announced a restructuring plan (the “Restructuring Plan”) as part of our previously announced focus on implementing cost reductions and improving the efficiency of our operations, which consisted of a reduction in headcount (excluding pilots, maintenance and operations-support personnel). We estimated that we would incur approximately $14 million in total pre-tax charges in connection with the Restructuring Plan, primarily related to severance payments, employee benefits and equity-based compensation.
As of March 31, 2023, we have incurred $17.7 million of charges associated with the Restructuring Plan related to severance payments, employee benefits and equity-based compensation, which represents substantially all cash and non-cash charges expected under the Restructuring Plan. During the three months ended December 31, 2022, we recorded $7.2 million of expenses related to actions taken in the fourth quarter of 2022 and in connection with the Restructuring Plan. During the three months ended March 31, 2023, $10.5 million of expenses related to the Restructuring Plan were recorded in the Company’s condensed consolidated statement of net income, as follows (in thousands):
27

Cost of revenue | $ | 755 |
Technology and development | 2,299 |
Sales and marketing | 5,379 |
General and administrative | 2,058 |
Total restructuring expenses | $ | 10,491 |

Approximately $2.7 million of charges associated with the Restructuring Plan remained unpaid and were included within Accrued expenses in the Company’s condensed consolidated balance sheet as of March 31, 2023 and are expected to be paid during the second quarter of fiscal 2023.
16. INCOME TAXES
We are subject to U.S. federal, state and local income taxes with respect to our allocable share of any taxable income or loss from WUP, as well as any standalone income or loss Wheels Up generates. WUP is treated as a partnership for U.S. federal and most applicable state and local income tax purposes and generally does not pay income taxes in most jurisdictions. Instead, any taxable income or loss generated by WUP is passed through to and included in the taxable income or loss of its members, including Wheels Up. We are also subject to income taxes in the various foreign jurisdictions in which we operate.
We recorded income tax expense of $0.2 million for the three months ended March 31, 2023, and $0 for the three months ended March 31, 2022. The effective tax rate was (0.2) % for the three months ended March 31, 2023, and 0% for the three months ended March 31, 2022. Our effective tax rate for the three months ended March 31, 2023 differs from the federal statutory rate of 21% primarily due to a full valuation allowance against the majority of our net deferred tax assets where it is more likely than not that the deferred tax assets will not be realized and geographical mix of our earnings.
We currently expect the undistributed earnings of our foreign subsidiaries to be indefinitely reinvested. Accordingly, the Company has not provided for the tax effect, if any, of limited outside basis differences of its foreign subsidiaries. If these foreign earnings are repatriated to the U.S., or if the Company determines that such earnings are repatriated to the U.S., or if the Company determines that such earnings will be remitted in a future period, additional tax provisions may be required.
We evaluate the realizability of our deferred tax assets on a quarterly basis and establish valuation allowances when it is more likely than not that all or a portion of the deferred tax assets may not be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, and tax-planning strategies. As of March 31, 2023, we concluded, based on the weight of all available positive and negative evidence, that it is more likely than not that the majority of U.S. deferred tax assets will not be realized. Accordingly, a valuation allowance has been established on the majority of our net deferred tax assets in the U.S.
Additionally, the Company is subject to the income tax effects associated with the Global Intangible Low-Taxed Income (“GILTI”) provisions and treats the tax effects of GILTI as a current period expense in the period incurred.
On August 16, 2022, the U.S. government enacted the Inflation Reduction Act (“IRA Act”), which is effective January 1, 2023 and contains provisions implementing a 15% minimum corporate income tax and a 1% excise tax on stock repurchases. While we are continuing to evaluate the impact of the IRA Act, at this time, we do not believe it will have a material impact on our consolidated financial statements.

17. NET LOSS PER SHARE
The following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):

| Three Months Ended March 31, |  |
| 2023 |  | 2022 |  |  |  |
Numerator: |  |  |  |  |  |  |
Net loss attributable to Wheels Up Experience Inc. - basic and diluted | $ | (100,866) |  |  | $ | (88,653) |  |  |  |  |
Denominator: |  |  |  |  |  |  |
Weighted-average shares of Class A common stock outstanding - basic and diluted | 253,345,272 |  |  | 244,609,635 |  |  |  |  |
Basic and diluted net loss per share of Class A common stock | $ | (0.40) |  |  | $ | (0.36) |  |  |  |  |

There were no dividends declared or paid during each of the three months ended March 31, 2023 or 2022.
Basic and diluted net loss per share were computed using the two-class method. Shares of unvested restricted stock are considered participating securities, because these awards contain a non-forfeitable right to participate equally in any dividends prior to forfeiture of the restricted stock, if any, irrespective of whether the awards ultimately vest. All issued and outstanding shares of restricted stock are included in the weighted-average shares of Class A common stock outstanding.
WUP profits interests held by other members of MIP LLC are not subject to the net loss per share calculation until such time the vested WUP profits interests are actually exchanged for shares of Class A common stock.
The following securities were not included in the computation of diluted shares outstanding, because the effect would be anti-dilutive, and issuance of such shares is contingent upon the satisfaction of certain conditions which were not satisfied by the end of the period:

| Three Months Ended March 31, |  |
| 2023 |  | 2022 |  |  |  |
Warrants | 12,521,494 |  |  | 12,521,494 |  |  |  |  |
Earnout Shares | 9,000,000 |  |  | 9,000,000 |  |  |  |  |
RSUs(1) | 27,852,662 |  |  | 15,633,060 |  |  |  |  |
Stock options | 13,665,147 |  |  | 16,193,621 |  |  |  |  |
Total anti-dilutive securities | 63,039,303 |  |  | 53,348,175 |  |  |  |  |

(1) Includes RSUs, PSUs and CEO Market-Based RSUs outstanding as of March 31, 2023.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following management’s discussion and analysis of our financial condition and results of operations (“MD&A”) should be read in conjunction with our unaudited condensed consolidated financial statements and the related notes included in Part I, Item 1 of this Quarterly Report and our audited consolidated financial statements included in our most recent Annual Report on Form 10-K for the year ended December 31, 2022. This discussion contains forward-looking statements which involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements” included in this Quarterly Report. Unless the context otherwise requires, references in this MD&A section to “Wheels Up”, “we,” “us,” “our,” and “the Company” are intended to mean the business and operations of Wheels Up Experience Inc. and its consolidated subsidiaries.
Overview of Our Business
Wheels Up strives to disrupt private aviation by delivering innovative, accessible, travel through simple-to-use proprietary technology and mobile applications. We have become a recognized market leader and are redefining private flying by leveraging our unique technology-enabled marketplace platform. We connect flyers to private aircraft, and to one another, creating memorable lifestyle experiences.
We have a diversified and evolving business model generating revenue through flights, membership fees, management of aircraft and other services. Our chief operating decision maker, Kenny Dichter, our Chief Executive Officer and Chairman of our Board of Directors, reviews our financial information presented on a consolidated basis, and accordingly, we operate under one reportable segment, which is private aviation services.
Flight revenue includes both retail and wholesale charter. Wheels Up has one of the largest and most diverse mix of available aircraft in the industry. As of March 31, 2023, we had over 200 aircraft in our owned and leased fleet that includes Turboprops, Light, Midsize, Super-Midsize and Large-Cabin jets, approximately half of which are Wheels Up branded aircraft. As of March 31, 2023, we also had a managed fleet across all private aircraft cabin classes of over 100 aircraft and an extensive network of third-party operators available in our program fleet from whom we can access over 1,200 additional safety vetted and verified partner aircraft.
Members pay a fixed quoted amount for flights plus certain incidental or additional costs, if applicable. The quoted amount can be based on a contractual capped hourly rate or dynamically priced based on a number of variables at time of booking. Wholesale customers, such as charter flight brokers and third-party operators, primarily pay a fixed rate for flights. Members are also able to purchase dollar-denominated credits that can be applied to future costs incurred by members, including annual dues, flight services and other incidental costs such as catering and ground transportation (“Prepaid Blocks”). Prepaid Block sales allow us to have a certain amount of revenue visibility into future flight and travel demand, and are an important source of cash for our operations. Members who elect not to purchase a Prepaid Block “pay as they fly” by paying for their flights at the time of booking or after their flights based on then-current market rates.
Membership revenue is generated from initiation and annual renewal fees across three different annual subscription tiers — Connect, Core and Business — each of which is designed to provide the varying services required across a range of existing and potential private flyers. Core membership is ideal for the more frequent individual private flyer who wants guaranteed availability and pricing, high-touch account management, capped rates and values ultimate convenience and flexibility. The Business membership is best suited for companies of any size that want a broader group of individuals in their organization to be able to book and fly, while also requiring maximum flexibility to meet their business needs. Our Business customers include companies that fully-outsource their private travel solution to Wheels Up, including but not necessarily managing their privately owned aircraft, and those that use Wheels Up to serve or supplement their in-house flight desks. We have offered Core and Business memberships with guaranteed aircraft availability and fixed rate pricing since our inception. The Connect membership, our introductory tier, offers variable rate pricing on a per trip basis and is designed for the consumer with less frequent flight needs or who has more flexibility in their schedule or does not seek capped rate pricing. All membership options provide access through the Wheels Up mobile app to on-demand charter flights, dynamic
30

pricing, a variety of Shared Flights, empty-leg Hot Flights, Shuttles and The Community, an online platform of members-only forums to facilitate flight sharing, enabling members to reduce their cost of flying private. In addition, customers can qualify for Delta Air Lines, Inc. (“Delta”) miles in the Delta SkyMiles Program as part of their membership.
In addition, non-member customers now have access to a full-scale marketplace of private aircraft through the Wheels Up mobile app, available on iOS and Android where they can view real-time dynamic pricing for available aircraft classes, making it possible to instantaneously search, book and fly. These flyers are not required to purchase a membership but may pay additional transaction fees not applicable to members and do not receive membership benefits. In addition, non-member flyers do not have aircraft availability guarantees as members do and flights are priced dynamically at rates that are not capped.
We also manage aircraft for owners in exchange for a recurring contractual fee. Under the terms of many of our management agreements, in addition to owners utilizing their own aircraft, the managed aircraft may be used by us to fulfill member and non-member flights on a revenue sharing arrangement with the owner. Revenue associated with the management of aircraft also includes the recovery of owner incurred expenses, as well as the recharging of certain incurred aircraft operating costs.
We earn other revenue from sales of whole aircraft, group charter, cargo, maintenance, repair and operations (“MRO”), ground services and fixed-base operator (“FBO”) activities. In addition, other revenue includes safety and security revenue, flight management software subscription fees from third-party operators for access to our proprietary cloud-based flight management system, UP FMS, sponsorships and partnership fees, and special missions revenue, including government, defense, emergency and medical transport.
Recent Developments
Operational Efficiency and Cost Reduction Initiatives
Member Program Changes
On May 9, 2023, we announced changes to our member program that we expect will better serve members and customers, while also improving our operational efficiency and flight margins. These member program changes include, among others, creating two primary service areas – one East of the Mississippi River and one focused in the Western region of the country – that we believe will allow us to better position our King Air and Light, Mid and Super-Midsize jet fleets to enhance flight experience and member service in our primary operating areas. We will continue to provide flight services to all regions in the United States. Regions outside of our primary service areas will be dynamically priced at competitive market rates. We currently expect these latest member program changes to take effect in June 2023. The nature of these program changes could cause financial variability in the short-term during the period of implementation. However, we believe that these program changes will support our previously announced goal of delivering positive Adjusted EBITDA in 2024.
Certificate Consolidation and Operational Efficiency Efforts
We expect the consolidation of our FAA operating certificates will simplify our flight operations by harmonizing our procedures across the entire company versus the multiple operating silos that exist today. In February 2023, we consolidated the legacy Alante Air Charter operations and our Cessna CJ3 aircraft onto one certificate. We anticipate that our certificate consolidation and related operational efficiency efforts will contribute meaningfully to our service delivery and financial results in future periods. In addition, we have also implemented changes to our aircraft fleet management and maintenance operations intended to improve the efficiency of our operations and the availability of our aircraft. We are also conducting a strategic review to further simplify our business and focus on our core charter operations, which could include divesting some of our non-core assets.
Restructuring Plan
In March 2023, we announced the adoption of a restructuring plan (the “Restructuring Plan”) as part of the Company’s previously announced focus on delivering positive Adjusted EBITDA in 2024. The Restructuring Plan is
31

intended to streamline the Company’s organization and reduce headcount in areas of the business that do not directly impact the Company’s operations or its customers’ experience. Excluded from these actions were key operationally focused employee groups such as pilots, maintenance and operations-support personnel.
Atlanta Member Operations Center
In October 2022, we announced our plan to relocate significant elements of our member operations team from Columbus, Ohio to Atlanta, Georgia, which will include construction of a 34,000 square foot Member Operations Center (the “Atlanta Member Operations Center”) and the relocation of certain employees to the Atlanta area. Establishment of the Atlanta Member Operations Center is expected to centralize our critical functions with the goal of better serving our members and customers. The Atlanta Member Operations Center is expected to open on May 15, 2023.
UP Global Response
In November 2022, we announced a partnership with AirMed International, a global leader in air medical transport, to bring an array of medical-travel services to our members and their families through our new UP Global Response membership offering. UP Global Response provides the member and up to 11 additional designated individuals with access to air medical transport from nearly any location in the world should they have a covered medical event while traveling more than 150 miles from home. The membership also includes access to a 24/7 global medical services referral hotline, and a transport of mortal remains benefit, among other features. We began offering the UP Global Response membership to our current and prospective members in January 2023.
Non-GAAP Financial Measures
In addition to our results of operations below, we report certain key financial measures that are not required by, or presented in accordance with, U.S. Generally Accepted Accounting Principles (“U.S. GAAP”).
These non-GAAP financial measures are in addition to, and not a substitute for, measures of financial performance prepared in accordance with U.S. GAAP and should not be considered as an alternative to any performance measures derived in accordance with U.S. GAAP. We believe that these non-GAAP financial measures of financial results provide useful supplemental information about Wheels Up to investors and are utilized internally by our management team to assess certain aspects of our performance. However, there are a number of limitations related to the use of these non-GAAP financial measures and their nearest U.S. GAAP equivalents, including that they exclude significant expenses that are required by U.S. GAAP to be recorded in Wheels Up’s financial measures. In addition, other companies may calculate non-GAAP financial measures differently or may use other measures to calculate their financial performance, and therefore, our non-GAAP financial measures may not be directly comparable to similarly titled measures of other companies.
Adjusted EBITDA
We calculate Adjusted EBITDA as net income (loss) adjusted for (i) interest income (expense), (ii) income tax expense, (iii) depreciation and amortization, (iv) equity-based compensation expense, (v) acquisition and integration related expenses and (vi) other items not indicative of our ongoing operating performance, including but not limited to, restructuring charges. We include Adjusted EBITDA as a supplemental measure for assessing operating performance and for the following:
•To be used in conjunction with bonus program target achievement determinations, strategic internal planning, annual budgeting, allocating resources and making operating decisions; and
•To provide useful information for historical period-to-period comparisons of our business, as it removes the effect of certain non-cash expenses and variable amounts.
32

The following table reconciles Adjusted EBITDA to net loss, which is the most directly comparable U.S. GAAP measure (in thousands):

| Three Months Ended March 31, |  |

(5)Includes collections of certain aged receivables which were added back to Net Loss in the reconciliation presented for the three and twelve months ended December 31, 2022.
Adjusted Contribution and Adjusted Contribution Margin
We calculate Adjusted Contribution as gross profit (loss) excluding depreciation and amortization and adjusted further for equity-based compensation included in cost of revenue and other items included in cost of revenue that are not indicative of our ongoing operating performance. Adjusted Contribution Margin is calculated by dividing Adjusted Contribution by total revenue. We include Adjusted Contribution and Adjusted Contribution Margin as supplemental measures for assessing operating performance and for the following:
•To be used to understand our ability to achieve profitability over time through scale and leveraging costs; and
•To provide useful information for historical period-to-period comparisons of our business and to identify trends.

Key Operating Metrics
In addition to financial measures, we regularly review certain key operating metrics to evaluate our business, determine the allocation of resources and make decisions regarding business strategies. We believe that these metrics can be useful for understanding the underlying trends in our business.
The following table summarizes our key operating metrics:

| As of March 31, |  |
| 2023 |  | 2022 |  | % Change
Active Members | 12,285 |  |  | 12,424 |  |  | (1) | %
| Three Months Ended March 31, |  |
| 2023 |  | 2022 |  | % Change
Active Users | 13,336 |  |  | 12,547 |  |  | 6 | %
Live Flight Legs | 15,389 |  |  | 17,626 |  |  | (13) | %
Flight revenue per Live Flight Leg | $ | 15,060 |  |  | $ | 13,410 |  |  | 12 | %

Active Members
We define Active Members as the number of Connect, Core and Business membership accounts that generated membership revenue in a given period and are active as of the end of the reporting period. We use Active Members
34

to assess the adoption of our premium offerings which is a key factor in our penetration of the market in which we operate and a key driver of membership and flight revenue.
Active Users
We define Active Users as Active Members as of the reporting date plus unique non-member consumers who completed a revenue generating flight at least once in a given period and excluding wholesale flight activity. While a unique consumer can complete multiple revenue generating flights on our platform in a given period, that unique user is counted as only one Active User. We use Active Users to assess the adoption of our platform and frequency of transactions, which are key factors in our penetration of the market in which we operate and our growth in revenue.
Live Flight Legs
We define Live Flight Legs as the number of completed one-way revenue generating flight legs in a given period. The metric excludes empty repositioning legs and owner legs related to aircraft under management. We believe Live Flight Legs are a useful metric to measure the scale and usage of our platform, and our growth in flight revenue.

The key components of our results of operations include:
Revenue
Revenue is derived from flight, membership, aircraft management and other services.
Flight revenue consists of retail and wholesale flights and certain related fees and surcharges. Members can either pay as they fly or prepay for flights when they purchase a Prepaid Block.
Membership revenue is comprised of a one-time initiation fee paid at the commencement of a membership and recurring annual dues. In the first year of membership, a portion of the initiation fee is applied to annual dues. The remainder of the initiation fee, less any flight credits, is deferred and recognized on a straight-line basis over the estimated duration of the customer relationship period, which is estimated to be three years as of March 31, 2023. Members are charged recurring annual dues to maintain their membership. Revenue related to the annual dues are deferred and recognized on a straight-line basis over the related contractual period. If a member qualifies to earn Delta miles in the Delta SkyMiles Program as part of their membership, then a portion of the membership fee is allocated at contract inception.
Aircraft management revenue consists of contractual monthly management fees charged to aircraft owners, recovery of owner incurred expenses including maintenance coordination, cabin crew and pilots, and recharging of certain incurred aircraft operating costs such as maintenance, fuel, landing fees and parking. We pass recovery and recharge amounts back to owners at either cost or at a predetermined margin.
Other revenue primarily consists of (i) sales of whole aircraft, (ii) group charter revenue, (iii) cargo revenue, and (iv) MRO and FBO revenues. In addition, other revenue includes safety and security revenue, flight management software subscription fees from third-party operators for access to UP FMS, fees from third-party sponsorships and partnership fees, and special missions revenue, including government, defense, emergency and medical transport.
Costs and Expenses
Costs and expenses consist of the following components:
Cost of Revenue
Cost of revenue primarily consists of direct expenses incurred to provide flight services and facilitate operations, including aircraft lease costs, fuel, crew travel, maintenance and third-party flight costs. Cost of revenue
35

also consists of compensation expenses, including equity-based compensation and related benefits for employees that directly facilitate flight operations. In addition, cost of revenue includes aircraft owner expenses incurred such as maintenance coordination, cabin crew and pilots, and certain aircraft operating costs such as maintenance, fuel, landing fees and parking.
Technology and Development
Technology and development expense primarily consists of compensation expenses for engineering, product development and design employees, including equity-based compensation, expenses associated with ongoing improvements to, and maintenance of, our platform offerings and other technology. Technology and development expense also includes software expenses and technology consulting fees.
Sales and Marketing
Sales and marketing expense primarily consists of compensation expenses in support of sales and marketing such as commissions, salaries, equity-based compensation and related benefits. Sales and marketing expense also includes expenses associated with advertising, promotions of our services, member experience, account management and brand-building.
General and Administrative
General and administrative expense primarily consists of compensation expenses, including allocable portions of equity-based compensation and related benefits for our executive, finance, human resources and legal teams, and other personnel performing administrative functions. General and administrative expense also includes corporate office rent expense, third-party professional fees, acquisition and integration related expenses, and any other cost or expense incurred not deemed to be related to cost of revenue, sales and marketing expense or technology and development expense.
We allocate overhead such as facility costs and telecommunications charges, based on department headcount, as we believe this to be the most accurate measure. As a result, a portion of general overhead expenses are reflected in each operating expense category.
Depreciation and Amortization
Depreciation and amortization expense primarily consists of depreciation of capitalized aircraft as well as amortization of capitalized software development costs and acquired finite-lived intangible assets.
Gain on Sale of Aircraft Held for Sale
Gain on sale of aircraft held for sale consists of the gain on aircraft previously held as property and equipment and subsequently elected to actively market for sale or aircraft purchased where our intent to sell and not to hold the asset long-term.
Change in Fair Value of Warrant Liability
Change in fair value of warrant liability consists of unrealized gain (loss) on warrants assumed as part of the business combination consummated on July 13, 2021 between Wheels Up Partners Holdings LLC, a Delaware limited liability company (“WUP”), and Aspirational Consumer Lifestyle Corp. (“Aspirational”), a blank check company (the “Business Combination’), including 7,991,544 public warrants (“Public Warrants”) and 4,529,950 private warrants (the “Private Warrants” and, together with the Public Warrants, the “Warrants”).
Interest Income
Interest income primarily consists of interest earned on cash equivalents in money market funds, U.S. treasury bills and time deposits.
36

Interest Expense
Interest expense primarily consists of the interest paid or payable and the amortization of debt discounts and deferred financing costs on our credit facilities, promissory notes and other debt obligations.
Income Tax Expense
Income tax expense consists of income taxes recorded using the asset and liability method. Under this method, deferred tax assets and liabilities are recorded based on the estimated future tax effects of differences between the financial reporting and tax bases of existing assets and liabilities. These differences are measured using the enacted tax rates that are expected to be in effect when these differences are anticipated to reverse. Deferred tax assets are reduced by a valuation allowance to the extent management believes it is not more likely than not to be realized.

Revenue
Revenue increased by 8.0%, or $26.2 million, for the three months ended March 31, 2023, compared to the three months ended March 31, 2022, as follows (in thousands, except percentages).

| Three Months Ended March 31, |  | Change in
2023 |  | 2022 |  | $ |  | %
Membership | $ | 21,680 |  |  | $ | 20,647 |  |  | $ | 1,033 |  |  | 5.0 | %
Flight | 231,762 |  |  | 236,363 |  |  | (4,601) |  |  | (1.9) | %
Aircraft management | 63,694 |  |  | 60,506 |  |  | 3,188 |  |  | 5.3 | %
Other | 34,676 |  |  | 8,119 |  |  | 26,557 |  |  | 327.1 | %
Total | $ | 351,812 |  |  | $ | 325,635 |  |  | $ | 26,177 |  |  | 8.0 | %

Membership revenue increased 5.0% year-over-year. The 1% decrease in Active Members year-over-year was offset by a higher mix of Core members combined with lower incentives on memberships.
The decrease in Flight revenue was primarily driven by a 13% decrease in Live Flight Legs year-over-year, which resulted in a $30.0 million reduction to revenue during the period, partially offset by a 12% increase in flight revenue per Live Flight Leg, which drove $25.4 million of year-over-year revenue increase. The decrease in Flight revenue for the three months ended March 31, 2023 was partially offset by $10.7 million of fuel surcharge revenue, which we began collecting effective April 1, 2022 and modified to a fuel surcharge indexed to fuel prices effective June 1, 2022, as well as $8.5 million of flight revenue attributable to Air Partner plc (“Air Partner”), which we acquired on April 1, 2022.
The increase in Aircraft management revenue was primarily attributable to an increase in our recovery of owner and rechargeable costs related to operating aircraft under management, both of which stemmed from an increase in operating costs.
The increase in Other revenue was primarily attributable to a $9.6 million increase in sales of aircraft inventory and a $14.3 million increase attributable to Air Partner for the three months ended March 31, 2023.
Cost of Revenue
Cost of revenue increased by $21.0 million, or 6%, for the three months ended March 31, 2023 compared to the three months ended March 31, 2022. The increase in cost of revenue is primarily attributable sales of aircraft inventory, cost of revenue attributable to Air Partner and one-time expenses associated with certificate consolidation and set-up of our Atlanta Member Operations Center. The increase was partially offset by a decrease in equity-based compensation expense associated with historical awards which vested prior to or within the current period.
Adjusted Contribution Margin decreased 260 basis points for the three months ended March 31, 2023 compared to the three months ended March 31, 2022, which was primarily attributable to fixed costs while we experienced lower live flight legs combined with cost pressures impacting us and the industry, partially offset by increased whole aircraft sales during the period. Specifically, reduced maintenance availability, which can result in lower utility or higher procurement costs, increased crew travel costs and wage inflation each contributed to the decline in Adjusted Contribution Margin. See “Non-GAAP Financial Measures” above for a definition of Adjusted Contribution Margin, information regarding our use of Adjusted Contribution Margin and a reconciliation of gross margin to Adjusted Contribution Margin.
Other Operating Expenses
Technology and Development
Technology and development expenses increased by $4.7 million, or 41.8%, for the three months ended March 31, 2023 compared to the three months ended March 31, 2022, primarily attributable to a $6.3 million increase in employee compensation and allocable costs, including $2.3 million of one-time charges associated with the
39

Restructuring Plan. The increase was also attributable to a $1.3 million increase in enterprise software expense and $1.0 million of expenses attributable to Air Partner. The increase was partially offset by a $1.3 million decrease in IT equipment spend.
Sales and Marketing
Sales and marketing expenses increased by $2.6 million, or 11.0%, for the three months ended March 31, 2023 compared to the three months ended March 31, 2022, primarily attributable to $7.2 million of expenses attributable to Air Partner, of which $1.2 million were one-time charges incurred associated with the Restructuring Plan, as well as $0.9 million of other one-time charges associated with the Restructuring Plan charges. The increase was partially offset by a $2.0 million decrease in equity-based compensation associated with historical awards which vested prior to or within the current period, a $1.1 million decrease in events spending, a $1.7 million decrease in employee compensation and allocable costs, due in part to the effect of the Restructuring Plan, and a $0.5 million decrease in advertising spend.
General and Administrative
General and administrative expenses increased by $0.5 million, or 1.3%, for the three months ended March 31, 2023 compared to the three months ended March 31, 2022, primarily attributable to $5.5 million of expenses attributable to Air Partner, $5.4 million in one-time restructuring charges associated with the Restructuring Plan, a $2.7 million increase year-over-year, and $0.7 million in one-time costs related to the set-up of the Atlanta Member Operations Center. The increase was also attributable to a $1.8 million increase in acquisition and integration charges and a $0.9 million increase in professional fees. The increases were partially offset by a $5.7 million decrease in equity-based compensation associated with historical awards which vested prior to or within the current period, a $3.5 million decrease in acquisition-related consulting charges and a $1.9 million decrease in legal-related charges.
Depreciation and Amortization
Depreciation and amortization expenses were relatively flat for the three months ended March 31, 2023 compared to the three months ended March 31, 2022.
Interest Income
Interest income increased by $3.7 million, for the three months ended March 31, 2023 compared to the three months ended March 31, 2022. The increase was attributable to higher rates of interest earned on cash equivalents in money market funds.
Interest Expense
Interest expense was $8.1 million for the three months ended March 31, 2023 with no comparable amount in the three months ended March 31, 2022. The increase was attributable to the Equipment Notes (as defined below) issued in October 2022.
Other Expense, Net
Other expense, net was relatively flat for the three months ended March 31, 2023 compared to the three months ended March 31, 2022.
Liquidity and Capital Resources
Overview
Our principal sources of liquidity have historically consisted of financing activities, including proceeds from the Business Combination and debt financing transactions, and operating activities, primarily from the increase in
40

deferred revenue associated with the sale of Prepaid Blocks. As of March 31, 2023, we had $363.2 million of cash and cash equivalents, which were primarily invested in money market funds, and $36.6 million of restricted cash.
Long-Term Debt
From time to time, we obtain debt financing to, among other things, refinance or purchase aircraft or fund our strategic growth initiatives. In October 2022, Wheels Up Partners LLC, our indirect subsidiary ("WUP LLC"), entered into a Note Purchase Agreement, dated as of October 14, 2022 (“Note Purchase Agreement”), pursuant to which WUP LLC issued $270.0 million aggregate principal amount of the equipment notes (collectively, the “Equipment Notes”) using an EETC (enhanced equipment trust certificate) loan structure. The Equipment Notes bear interest at the rate of 12% per annum with annual amortization of principal amount equal to 10% per annum and balloon payments due at each maturity date. Interest and principal payments on the Equipment Notes are payable quarterly on each January 15, April 15, July 15 and October 15, which began on January 15, 2023. The Equipment Notes are secured by first-priority liens on 134 of the Company’s owned aircraft fleet and by liens on certain intellectual property assets of the Company and certain of its subsidiaries.
The Equipment Notes were sold pursuant to the Note Purchase Agreement, and issued under separate Trust Indentures and Mortgages, dated as of October 14, 2022 (each, an “Indenture” and collectively, the “Indentures”). The Note Purchase Agreement and the Indentures and related guarantees contain certain covenants, including a liquidity covenant that requires the Company to maintain minimum liquidity of $125 million, a covenant that limits the maximum loan to appraised value ratio of all aircraft financed, subject to certain cure rights of the Company, and restrictive covenants that provide limitations under certain circumstances on, among other things: (i) certain acquisitions, mergers or disposals of its assets; (ii) making certain investments or entering into certain transactions with affiliates; (iii) prepaying, redeeming or repurchasing the Equipment Notes, subject to certain exceptions; and (iv) paying dividends and making certain other specified restricted payments. Each Indenture contains customary events of default for Equipment Notes of this type, including cross-default provisions among the Equipment Notes. WUP LLC’s obligations under the Equipment Notes are guaranteed by the Company and certain of its subsidiaries. WUP LLC is also obligated to cause additional subsidiaries and affiliates of WUP LLC to become guarantors under certain circumstances.
As of March 31, 2023, approximately $263.2 million aggregate principal amount of Equipment Notes were outstanding and the carrying value of the aircraft that are subject to first-priority liens under the Equipment Notes was $323.4 million.
Cash Flows
The following table summarizes our cash flows for each of the three months ended March 31, 2023 and 2022 (in thousands):

| Three Months Ended March 31,
| 2023 |  | 2022
Net cash used in operating activities | $ | (202,482) |  |  | $ | (121,216) |
Net cash used in investing activities | $ | (11,035) |  |  | $ | (119,552) |
Net cash provided by (used in) financing activities | $ | (6,752) |  |  | $ | (6,107) |
Effect of exchange rate changes on cash, cash equivalents and restricted cash | $ | (86) |  |  | $ | — |
Net increase (decrease) in cash, cash equivalents and restricted cash | $ | (220,355) |  |  | $ | (246,875) |

Cash Flow from Operating Activities
The cash outflow from operating activities consisted of our net loss, net of non-cash items of $25.9 million and the balance from an increase in net operating assets and liabilities. During the three months ended March 31, 2023, we sold $99.9 million of Prepaid Blocks compared to $174.6 million during the three months ended March 31, 2022. The year-over-year decrease in Prepaid Block purchases was primarily attributable to normalization of supply versus demand for aviation services.
41

Cash Flow from Investing Activities
The cash outflow from investing activities was primarily attributable to $16.7 million for capital expenditures, including $8.0 million of software development costs. The cash outflow was partially offset by $5.7 million in proceeds from the sale of aircraft that were classified as held for sale.
Cash Flow from Financing Activities
The cash outflow from financing activities was attributable to the payment of principal on the Equipment Notes.
Contractual Obligations and Commitments
As of March 31, 2023, our principal commitments consisted of contractual cash obligations under the Equipment Notes, operating leases for certain controlled aircraft, corporate headquarters, and operational facilities, including aircraft hangars, and ordinary course arrangements involving our obligation to provide services for which we have already received deferred revenue. For further information on the Equipment Notes, see “—Long-Term Debt” above and Note 7, Long-Term Debt of the Notes to Condensed Consolidated Financial Statements included herein. For further information about our lease obligations, see Note 9, Leases of the Notes to Condensed Consolidated Financial Statements included herein.

For further information on recent accounting pronouncements, see Note 1, Summary of Business and Significant Accounting Policies of the Notes to Condensed Consolidated Financial Statements included herein.
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, aircraft fuel and foreign currency exchange. There has not been any material change to the information included in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2022.
42

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 the period covered by this Quarterly Report on Form 10-Q. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of March 31, 2023, due to the on-going remediation efforts associated with the material weaknesses in internal control over financial reporting described in Item 9A of our Annual Report on Form 10-K for the year ended December 31, 2022 (the “Annual Report”) and the need for impacted controls to operate for a sufficient period of time and for management to conclude, through testing, that the controls are designed and operating effectively.
Notwithstanding the pending remediation efforts described below, based on additional analysis and other post-closing procedures performed, 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.
Remediation Plans to Address Material Weaknesses
To date, we have implemented certain measures to address the controls and procedures deficiencies identified in Item 9A of the Annual Report. These measures include (i) adding key personnel, (ii) improving our internal controls around financial systems and processes and (iii) designing and operating user access and change management controls. We intend to take additional steps to remediate the deficiencies identified in Item 9A of the Annual Report and further evolve our internal controls and processes.
Since the date of the Annual Report, we have taken the following steps as part of our remediation plan:
•implemented preventative controls to better ensure segregation of duties; and
•improved system capabilities around posting of journal entries, enhancing journal entry review and approval controls.
Our remediation plan includes the following actions that management intends to undertake during the remainder of the fiscal year ending December 31, 2023:
•ensuring that the IT general controls specific to all key systems supporting financial reporting, including user access reviews, are consistently operating and evidenced; and
•formalizing our accounting policies and ensuring training of relevant personnel on the importance of internal controls and compliance with policies.
We are working aggressively and prioritizing the above actions to complete our remediation plan before the end of the second quarter of the fiscal year ending December 31, 2023, but no later than the end of the fiscal year. As we continue to evaluate and improve the applicable controls, management may take additional remedial measures or modify the remediation plan described above. We believe that these actions, when fully implemented, will remediate the deficiencies identified in Item 9A of the Annual Report. The deficiencies will not be considered remediated until
43

the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are designed and operating effectively.
Changes in Internal Control over Financial Reporting
Except for the items referred to above, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended March 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
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.
44

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.
