UNITED AIRLINES HOLDINGS, INC. AND UNITED AIRLINES, INC.
COMBINED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company and its wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United"). This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.
The UAL and United unaudited condensed consolidated financial statements shown here have been prepared as required by the U.S. Securities and Exchange Commission (the "SEC"). Some information and footnote disclosures normally included in financial statements that comply with accounting principles generally accepted in the United States ("GAAP") have been condensed or omitted as permitted by the SEC. The financial statements include all adjustments, including normal recurring adjustments and other adjustments, which are considered necessary for a fair presentation of the Company's financial position and results of operations for interim periods presented. The UAL and United financial statements should be read together with the information included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the "2022 Form 10-K"). The Company's quarterly financial data is subject to seasonal fluctuations. Historically its second and third quarter financial results have reflected higher travel demand, and were better than its first and fourth quarter financial results.
NOTE 1 — REVENUE
Revenue by Geography. The table below presents the Company's operating revenue by principal geographic region (as defined by the U.S. Department of Transportation) (in millions):

| Three Months Ended March 31, |  |
| 2023 |  | 2022 |  |  |  |
Domestic (U.S. and Canada) | $ | 7,167 |  |  | $ | 5,086 |  |  |  |  |
Atlantic (including Europe, Africa, India and Middle East destinations) | 1,832 |  |  | 1,089 |  |  |  |  |
Latin America | 1,316 |  |  | 909 |  |  |  |  |
Pacific | 1,114 |  |  | 482 |  |  |  |  |
Total | $ | 11,429 |  |  | $ | 7,566 |  |  |  |  |

Advance Ticket Sales. The Company defers amounts related to future travel in its Advance ticket sales liability account. All tickets sold at any given point in time have travel dates through the next 12 months. The Company's Advance ticket sales liability also includes credits issued to customers for future flights ("FFCs") and electronic travel certificates ("ETCs"), primarily for ticket cancellations, which can be applied towards a purchase of a new ticket. FFCs and ETCs are valid up to one year from the date of issuance; however, all credits issued on or before December 31, 2022 have been extended to December 31, 2023.
The Company estimates the value of Advance tickets sales that will expire unused ("breakage") and recognizes revenue in proportion to the usage of the related tickets. To determine breakage, the Company uses its historical experience with expired tickets and certificates and other facts, such as recent aging trends, program changes and modifications that could affect the ultimate expiration patterns. Changes in our estimates of FFCs and ETCs that may expire unused could have a material impact on revenue. Changes in estimates of breakage are recognized prospectively in proportion to the remaining usage of the related tickets.
In the three months ended March 31, 2023 and 2022, the Company recognized approximately $3.5 billion and $1.9 billion, respectively, of passenger revenue for tickets that were included in Advance ticket sales at the beginning of those periods.
Ancillary Fees. The Company charges fees, separately from ticket sales, for certain ancillary services that are directly related to passengers' travel, such as baggage fees, premium seat fees, inflight amenity fees and other ticket-related fees. These ancillary fees are part of the travel performance obligation and, as such, are recognized as passenger revenue when the travel occurs. The Company recorded $892 million and $661 million of ancillary fees within passenger revenue in the three months ended March 31, 2023 and 2022, respectively.

MileagePlus co-brand agreement. The portion related to the MileagePlus miles awarded of the total amounts received from our various partner agreements is deferred and presented in the table above as an increase to the Frequent flyer deferred revenue. We determine the current portion of that account based on expected redemptions in the next 12 months.
NOTE 2 — LOSS PER SHARE
The computations of UAL's basic and diluted loss per share are set forth below (in millions, except per share amounts):

| Three Months Ended March 31, |  |

Loss available to common stockholders | $ | (194) |  |  | $ | (1,377) |  |  |  |  |
Weighted-average shares outstanding, basic and diluted | 327.4 |  |  | 325.0 |  |  |  |  |

Stock warrants (b) | 1.5 |  |  | 1.5 |  |  |  |  |
Employee stock awards | 0.7 |  |  | 0.7 |  |  |  |  |
(a) Weighted-average potentially dilutive securities outstanding excluded from the computation of diluted earnings per share because the securities would have had an antidilutive effect.
(b) Represent warrants issued to the U.S. Treasury Department ("Treasury") pursuant to the payroll support program, including extensions, and the loan program established under the Coronavirus Aid, Relief, and Economic Security Act. The Company issued, to Treasury, warrants to purchase up to approximately 10 million shares of UAL common stock at exercise prices ranging from $31.50 to $53.92 and expiration dates ranging from April 20, 2025 to June 10, 2026. All warrants were outstanding as of March 31, 2023.

On March 3, 2021, the Company entered into an equity distribution agreement (the "Distribution Agreement") with several financial institutions (collectively, the "Managers"), relating to the issuance and sale from time to time by UAL (the "2021 ATM Offering"), through the Managers, of up to 37 million shares of UAL common stock (the "2021 ATM Shares"). Sales of the 2021 ATM Shares under the Distribution Agreement were allowed to be made in any transactions that were deemed to be "at the market offerings" as defined in Rule 415 under the Securities Act of 1933, as amended. During 2021, approximately 4 million shares were sold in the 2021 ATM Offering at an average price of $57.50 per share, with net proceeds to the Company totaling approximately $250 million. No shares were sold in 2022 or 2023 under the 2021 ATM Offering, which expired in March 2023.

NOTE 3 — ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)
The table below presents the components of the Company's accumulated other comprehensive income (loss), net of tax ("AOCI") (in millions):

|  | Pension and Other Postretirement Liabilities |  | Investments and Other |  | Deferred Taxes (a) |  | Total
Balance at December 31, 2022 |  | $ | 626 |  |  | $ | (35) |  |  | $ | (416) |  |  | $ | 175 |
Changes in value |  | (9) |  |  | 27 |  |  | (4) |  |  | 14 |
Amounts reclassified to earnings |  | (35) |  | (b) | — |  |  | 7 |  |  | (28) |
Balance at March 31, 2023 |  | $ | 582 |  |  | $ | (8) |  |  | $ | (413) |  |  | $ | 161 |
Balance at December 31, 2021 |  | $ | (847) |  |  | $ | — |  |  | $ | (95) |  |  | $ | (942) |
Changes in value |  | 8 |  |  | — |  |  | (3) |  |  | 5 |
Balance at March 31, 2022 |  | $ | (839) |  |  | $ | — |  |  | $ | (98) |  |  | $ | (937) |

(a) Includes approximately $285 million of deferred income tax expense that will not be recognized in net income until the related pension and postretirement benefit obligations are fully extinguished. We consider all income sources, including other comprehensive income, in determining the amount of tax benefit allocated to results from operations.
(b) This AOCI component is included in the computation of net periodic pension and other postretirement costs, specifically the following components: amortization of unrecognized (gain) loss, amortization of prior service credit and other (see Note 5 of this report for additional information).
NOTE 4 — INCOME TAXES
The Company's effective tax rates for the three months ended March 31, 2023 and March 31, 2022 were 24.2% and 21.4%, respectively. The provision for income taxes for the three months ended March 31, 2023 is based on the estimated annual effective tax rate, which represents a blend of federal, state and foreign taxes and includes the impact of certain nondeductible items. The provision for income taxes for the three months ended March 31, 2022 is calculated using a discrete effective tax rate method. We determined that applying an estimate of the annual effective tax rate to income or loss for the interim reporting period would not provide a reliable estimate for the three months ended March 31, 2022, since small changes in estimated income would have resulted in significant changes in the estimated annual effective tax rate.
NOTE 5 — EMPLOYEE BENEFIT PLANS
The Company's net periodic benefit cost includes the following components for the three months ended March 31 (in millions):

|  | Pension Benefits |  | Other Postretirement Benefits |  | Affected Line Item in the Statements of Consolidated Operations
|  | 2023 |  | 2022 |  | 2023 |  | 2022 |  |
Service cost |  | $ | 31 |  |  | $ | 51 |  |  | $ | 1 |  |  | $ | 2 |  |  | Salaries and related costs

Amortization of unrecognized (gain) loss |  | 2 |  |  | 30 |  |  | (9) |  |  | (3) |  |  | Miscellaneous, net

Boeing may inform United that additional Boeing 737 MAX 8 aircraft scheduled for delivery in the third quarter of 2023 may be delayed and/or that certain Boeing 737 MAX aircraft currently expected to be delivered in 2023 may deliver in 2024. However, at this time, we do not expect these delays to be extensive or to have a significant impact on our capacity plan for 2023.
During the first quarter of 2023, United entered into agreements with third parties to finance through sale and leaseback transactions new Boeing model 737 MAX aircraft subject to purchase agreements between United and Boeing. For certain aircraft, United assigned its right to purchase such aircraft to the buyer, and simultaneous with the buyer's purchase from Boeing, United entered into a long-term lease for such aircraft with the buyer as lessor. Upon delivery of the aircraft in these sale and leaseback transactions, the Company accounted for these aircraft as part of Flight equipment on the Company's

consolidated balance sheet and the related obligation recorded in Current maturities of other financial liabilities and Other financial liabilities since they did not qualify for sale recognition (failed sale and leaseback).
The table below summarizes United's commitments as of March 31, 2023, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments for the delays communicated by Boeing and Airbus or estimated by United.

Regional CPAs. In the first quarter of 2023, United amended its CPA agreements with one of its regional carriers to increase the contractually agreed fees (carrier costs) paid to that carrier. The Company expects to wind down its CPA with Air Wisconsin and terminate operations by early June 2023. Our future commitments under our CPAs are dependent on numerous variables, and are, therefore, difficult to predict. The most important of these variables is the number of scheduled block hours. Although we are not required to purchase a minimum number of block hours under certain of our CPAs, we have set forth below estimates of our future payments under the CPAs based on our assumptions. The actual amounts we pay to our regional operators under CPAs could differ materially from these estimates. United's estimates of its future payments under all of the CPAs do not include the portion of the underlying obligation for any aircraft leased to a regional carrier or deemed to be leased from other regional carriers and facility rent that are disclosed as part of operating leases above. For purposes of calculating these estimates, we have assumed (1) the number of block hours flown is based on our anticipated level of flight activity or at any contractual minimum utilization levels if applicable, whichever is higher, (2) that we will reduce the fleet as rapidly as contractually allowed under each CPA, (3) that aircraft utilization, stage length and load factors will remain constant, (4) that each carrier's operational performance will remain at recent historic levels and (5) an annual projected inflation rate. Based on these assumptions as of March 31, 2023, our estimated future payments through the end of the terms of our CPAs are presented in the table below:

Guarantees. As of March 31, 2023, United is the guarantor of approximately $2.0 billion in aggregate principal amount of tax-exempt special facilities revenue bonds and interest thereon. These bonds, issued by various airport municipalities, are payable solely from rentals paid under long-term agreements with the respective governing bodies. The leasing arrangements associated with these obligations are accounted for as operating leases recognized on the Company's consolidated balance sheet with the associated expense recorded on a straight-line basis over the expected lease term. All of these bonds are due between 2023 and 2041.
As of March 31, 2023, United is the guarantor of $88 million of aircraft mortgage debt issued by one of United's regional carriers. The aircraft mortgage debt is subject to similar increased cost provisions as described below for the Company's debt, and the Company would potentially be responsible for those costs under the guarantees.
Increased Cost Provisions. In United's financing transactions that include loans in which United is the borrower, United typically agrees to reimburse lenders for any reduced returns with respect to the loans due to any change in capital requirements and, in the case of loans with respect to which the interest rate is based on the London Interbank Offered Rate (LIBOR) or the Secured Overnight Financing Rate (SOFR), for certain other increased costs that the lenders incur in carrying these loans as a
20

result of any change in law, subject, in most cases, to obligations of the lenders to take certain limited steps to mitigate the requirement for, or the amount of, such increased costs. At March 31, 2023, the Company had $12.9 billion of floating rate debt with remaining terms of up to approximately 12 years that are subject to these increased cost provisions. In several financing transactions involving loans or leases from non-U.S. entities, with remaining terms of up to approximately 12 years and an aggregate balance of $9.7 billion, the Company bears the risk of any change in tax laws that would subject loan or lease payments thereunder to non-U.S. entities to withholding taxes, subject to customary exclusions.
Labor. As of March 31, 2023, the Company had approximately 96,300 employees, of whom approximately 84% were represented by various U.S. labor organizations.
In January 2023, United and the International Brotherhood of Teamsters ratified an extension to its labor contract covering the Company's more than 8,000 technicians and related employees. The agreement becomes amendable in December 2024 and includes a one-year early opener that allows for bargaining on a successor agreement to begin in December 2023.
In April 2023, the Company and the International Association of Machinists & Aerospace Workers ("IAM") reached a tentative agreement covering nearly 30,000 IAM-represented employees in several workgroups. The agreements, once ratified, will cover IAM-represented employees across our operations and be effective through 2025.
The Company has been in negotiations with its employees represented by the Air Line Pilots Association ("ALPA") regarding a contract that became amendable in January 2019. Given the recent ratification of a new agreement by the pilot group of another major airline, the Company has determined that it is appropriate to accrue expense in the first quarter 2023 related to a potential new collective bargaining agreement with employees represented by ALPA.
NOTE 8 — DEBT
As of March 31, 2023, we had $1.75 billion undrawn and available under our revolving credit facility.
Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of March 31, 2023, UAL and United were in compliance with their respective debt covenants.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.
This Management's Discussion and Analysis of Financial Condition and Results of Operations is provided as a supplement to and should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q to enhance the understanding of our results of operations, financial condition and cash flows.
EXECUTIVE SUMMARY
Overview
United Airlines Holdings, Inc. (together with its consolidated subsidiaries, "UAL" or the "Company") is a holding company and its wholly-owned subsidiary is United Airlines, Inc. (together with its consolidated subsidiaries, "United").
This Quarterly Report on Form 10-Q is a combined report of UAL and United, including their respective consolidated financial statements. As UAL consolidates United for financial statement purposes, disclosures that relate to activities of United also apply to UAL, unless otherwise noted. United's operating revenues and operating expenses comprise nearly 100% of UAL's revenues and operating expenses. In addition, United comprises approximately the entire balance of UAL's assets, liabilities and operating cash flows. When appropriate, UAL and United are named specifically for their individual contractual obligations and related disclosures, and any significant differences between the operations and results of UAL and United are separately disclosed and explained. We sometimes use the words "we," "our," "us," and the "Company" in this report for disclosures that relate to all of UAL and United.
Our shared purpose is "Connecting People. Uniting the World." We have the most comprehensive route network among North American carriers, including U.S. mainland hubs in Chicago, Denver, Houston, Los Angeles, New York/Newark, San Francisco and Washington, D.C. The Company transports people and cargo through its mainline operations, which utilize jet aircraft with at least 126 seats, and regional operations, which utilize smaller aircraft that are operated under contract by United Express carriers. The Company serves virtually every major market around the world, either directly or through participation in Star Alliance®, the world's largest airline alliance.
Our current expectations described below are forward-looking statements and our actual results and timing may vary materially based on various factors that include, but are not limited to, those discussed below under "Economic and Market Factors" and "Forward-Looking Information" and in Part I, Item 1A. Risk Factors, in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the "2022 Form 10-K"). The Company discusses certain non-GAAP forward-looking projections and is unable to predict certain items contained in the corresponding GAAP measures without unreasonable efforts; refer to "Supplemental Information" below for further details. The results presented in this report are not necessarily indicative of future operating results.
Economic and Market Factors
The airline industry is highly competitive, marked by significant competition with respect to routes, fares, schedules (both timing and frequency), services, products, customer service and frequent flyer programs. We, like other companies in our industry, have been subject to these and other industry-specific competitive dynamics. In addition, our operations, supply chain, partners and suppliers have been subject to various global macroeconomic factors. We expect to continue to remain vulnerable to a number of industry-specific and global macroeconomic factors that may cause our actual results of operations to differ from our historical results of operations or current expectations. The factors and trends that we currently believe are or will be most impactful to our results of operations and financial condition include the following: the execution risks associated with our United Next plan; the impact on the Company of significant operational challenges by third parties on which we rely; rising inflationary pressures; labor market and supply chain constraints and related costs affecting us and our partners; volatile fuel prices; aircraft delivery delays; the lasting effects of the COVID-19 global pandemic and related governmental regulations and restrictions, which we believe will change how our customers fly in ways that we expect to be both positive and negative for the Company, including the lingering impact of the pandemic on the return of business and international travel demand—especially in our China market—to pre-COVID-19 levels; the closure of our flying airspace and termination of other operations due to regional conflicts, including the continuation of the suspension of our overflying in Russian airspace as well as third-party general sales agent services in Russia as a result of the Russia-Ukraine military conflict and an escalation of the broader economic consequences of the conflict beyond their current scope; and changes in general economic conditions in the markets in which the Company operates, including an economic downturn leading to a decrease in demand for air travel or fluctuations in foreign currency exchange rates that may impact international travel demand. We continue to monitor the potential favorable or unfavorable impacts of these and other factors on our business, operations, financial condition and future results of operations, which are dependent on future developments, including as a result of those factors discussed in Item 1A. Risk Factors, of the 2022 Form 10-K. Our future results of operations may be subject to volatility and our growth plans may be
23

Table of Contents |  |

delayed, particularly in the short term, due to the impact of the above factors and trends. Absent significant and prolonged COVID-19 relapses or global economic disruptions, we believe that the expected long-term increase in travel demand will offset increased costs and that the expected operational challenges can be managed in a manner that will allow us to support increased demand.
RESULTS OF OPERATIONS
The following discussion provides an analysis of our results of operations and reasons for material changes therein for the three months ended March 31, 2023, as compared to the corresponding period in 2022.
First Quarter 2023 Compared to First Quarter 2022

Passenger revenue increased $3.9 billion, or 61.8%, in the first quarter of 2023 as compared to the year-ago period, primarily due to an increase in capacity of 23.4% as well as strength in both yield and passenger load factor.
Cargo revenue decreased $229 million, or 36.5%, in the first quarter of 2023 as compared to the year-ago period, primarily due to lower yields and lower tonnage as a result of increased market capacity and rate pressures.
Other operating revenue increased $166 million, or 28.1%, in the first quarter of 2023 as compared to the year-ago period, primarily due to an increase in mileage revenue from non-airline partners, including credit card spending and new credit card member acquisitions with the co-branded credit card partner, JPMorgan Chase Bank, N.A., as well as an increase in the purchases of United Club memberships and one-time lounge passes.
Operating Expenses. The table below includes data related to the Company's operating expenses for the three months ended March 31 (in millions, except for percentage changes):

| 2023 |  | 2022 |  | Increase (Decrease) |  | % Change

Table of Contents |  |

Aircraft fuel expense increased by $944 million, or 42.3%, in the first quarter of 2023 as compared to the year-ago period, due to both a higher average price per gallon of fuel and increased consumption from higher flight activity.
The table below presents the significant changes in aircraft fuel cost per gallon in the three months ended March 31, 2023 as compared to the year-ago period (in millions, except percentage change and per gallon data):

| 2023 |  | 2022 |  | Increase (Decrease) |  | % Change
Fuel expense | $ | 3,174 |  |  | $ | 2,230 |  |  | $ | 944 |  |  | 42.3 | %
Fuel consumption (gallons) | 952 |  |  | 775 |  |  | 177 |  |  | 22.8 | %
Average price per gallon | $ | 3.33 |  |  | $ | 2.88 |  |  | $ | 0.45 |  |  | 15.6 | %

Landing fees and other rent increased $105 million, or 17.2%, in the first quarter of 2023 as compared to the year-ago period, primarily due to increased flying driving higher landed weight volume and higher number of enplaned passengers.
Aircraft maintenance materials and outside repairs increased $295 million, or 72.5%, in the first quarter of 2023 as compared to the year-ago period, primarily due to increased flight activity and increased volumes of both engine overhauls and airframe heavy maintenance checks.
Depreciation expense increased $44 million, or 7.2%, in the first quarter of 2023 as compared to the year-ago period, primarily due to new aircraft inducted into service.
Regional capacity purchase increased $50 million, or 8.8%, in the first quarter of 2023 as compared to the year-ago period despite an 18.3% regional capacity reduction primarily due to rate increases under various capacity purchase agreements with regional carriers.
Distribution expenses increased $177 million, or 78.3%, in the first quarter of 2023 as compared to the year-ago period, primarily due to higher credit card fees, agency commissions and global distribution fees driven by the overall increase in passenger revenue. Distribution expenses were also impacted by a higher proportion of business travel as compared to leisure travel, which can result in higher cost distribution channels and forms of payment.
Details of the Company's special charges (credits) include the following for the three months ended March 31 (in millions):

| 2023 |  | 2022
(Gains) losses on sale of assets and other special charges | $ | 14 |  |  | $ | (8) |
Special charges (credits) | $ | 14 |  |  | $ | (8) |

See Note 9 to the financial statements included in Part I, Item 1 of this report for additional information on the Company's special charges (credits).
Other operating expenses increased $363 million, or 25.0%, in the first quarter of 2023 as compared to the year ago period, primarily due to increases in ground handling, passenger services, food and beverage offerings, navigation fees and personnel-related costs as a direct result of the increase in flight activity and inflationary pressures and higher expenditures on information technology projects and services.
Nonoperating Income (Expense). The table below shows year-over-year comparisons of the Company's nonoperating income (expense) for the three months ended March 31 (in millions, except for percentage changes):

LIQUIDITY AND CAPITAL RESOURCES
Current Liquidity
As of March 31, 2023, the Company had $17.2 billion in unrestricted cash, cash equivalents and short-term investments, as compared to $16.4 billion at December 31, 2022. We believe that our existing cash, cash equivalents and short-term investments, together with cash generated from operations, will be sufficient to satisfy our anticipated liquidity needs for the next twelve months, and we expect to meet our long-term liquidity needs with our anticipated access to the capital markets and projected cash from operations. We regularly assess our anticipated working capital needs, debt and leverage levels, debt maturities, capital expenditure requirements (including in connection with our capital commitments for our firm order aircraft) and future investments or acquisitions in order to maximize shareholder return, efficiently finance our ongoing operations and maintain flexibility for future strategic transactions. We also regularly evaluate our liquidity and capital structure to ensure financial risks, liquidity access and cost of capital are each managed efficiently.
The Company has a $1.75 billion revolving credit facility (the "Revolving Credit Facility") expiring April 21, 2025 (subject to customary extension rights). The Revolving Credit Facility is secured by certain route authorities and airport slots and gates. No borrowings were outstanding under the Revolving Credit Facility at March 31, 2023.
We have a significant amount of fixed obligations, including debt, leases of aircraft, airport and other facilities, and pension funding obligations. As of March 31, 2023, the Company had approximately $37.2 billion of debt, finance lease, operating lease and other financial liabilities, including $3.9 billion that will become due in the next 12 months. In addition, we have substantial noncancelable commitments for capital expenditures, including the acquisition of certain new aircraft and related spare engines. Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional indebtedness and pay dividends or repurchase stock. As of March 31, 2023, UAL and United were in compliance with their respective debt covenants. As of March 31, 2023, a substantial portion of the Company's assets, principally aircraft and certain related assets, its loyalty program, certain route authorities and airport slots and gates, was pledged under various loan and other agreements. See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information on aircraft financing and other debt instruments.
The Company has backstop financing commitments available from certain of its aircraft manufacturers for a limited number of its future aircraft deliveries, subject to certain customary conditions. See Note 7 to the financial statements included in Part I, Item I of this report for additional information on commitments.
As of March 31, 2023, United had firm commitments and options to purchase aircraft from The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus") as presented in the table below:

|  |  |  | Scheduled Aircraft Deliveries
Aircraft Type |  | Number of Firm Commitments (a) |  | Last Nine Months of 2023 |  | 2024 |  | After 2024 |
787 |  | 100 |  |  | — |  |  | 8 |  |  | 92 |  |
737 MAX |  | 412 |  |  | 114 |  |  | 88 |  |  | 210 |  |
A321neo |  | 70 |  |  | 12 |  |  | 31 |  |  | 27 |  |
A321XLR |  | 50 |  |  | — |  |  | — |  |  | 50 |  |
A350 |  | 45 |  |  | — |  |  | — |  |  | 45 |  |
(a) United also has options and purchase rights for additional aircraft. |  |  |  |  |  |  |

The aircraft listed in the table above are scheduled for delivery through 2033. The amount and timing of the Company's future capital commitments could change to the extent that: (i) the Company and the aircraft manufacturers, with whom the Company has existing orders for new aircraft, agree to modify the contracts governing those orders; (ii) rights are exercised pursuant to
27

Table of Contents |  |

the relevant agreements to modify the timing of deliveries; or (iii) the aircraft manufacturers are unable to deliver in accordance with the terms of those orders. Airbus notified United that eight Airbus A321neo aircraft scheduled for delivery in 2023, as shown in the table above, are now expected to deliver in 2024 and ten Airbus A321neo aircraft scheduled for delivery in 2024, as shown in the table above, are now expected to deliver in 2025. Boeing notified United that 37 Boeing 737 MAX aircraft scheduled for delivery in 2023, as shown in the table above, are now expected to deliver in 2024. Also, United estimates that an additional eleven Boeing 737 MAX aircraft scheduled for delivery in 2023, as shown in the table above, will deliver in 2024 and 30 Boeing 737 MAX aircraft scheduled for delivery in 2024, as shown in table above, will deliver in 2025. Furthermore, Boeing recently notified United that due to a manufacturing process issue relating to certain Boeing 737 MAX fuselages, six Boeing 737 MAX 8 aircraft scheduled for delivery in the second quarter of 2023, as shown in the table above, will be delayed. Boeing may inform United that additional Boeing 737 MAX 8 aircraft scheduled for delivery in the third quarter of 2023 may be delayed and/or that certain Boeing 737 MAX aircraft currently expected to be delivered in 2023 may deliver in 2024. However, at this time, we do not expect these delays to be extensive or to have a significant impact on our capacity plan for 2023.
The table below summarizes United's commitments as of March 31, 2023, which include aircraft and related spare engines, aircraft improvements and non-aircraft capital commitments. Aircraft commitments are based on contractual scheduled aircraft deliveries without any adjustments for the delays communicated by Boeing and Airbus or estimated by United.

Sources and Uses of Cash
The following table summarizes our cash flows for the three months ended March 31 (in millions):

|  | 2023 |  | 2022 |  | Increase (Decrease)
Total cash provided by (used in): |  |  |  |  |  |
Operating activities |  | $ | 3,142 |  |  | $ | 1,476 |  |  | $ | 1,666 |
Investing activities |  | (1,968) |  |  | (430) |  |  | 1,538 |

Net increase in cash, cash equivalents and restricted cash |  | $ | 611 |  |  | $ | 190 |  |  | $ | 421 |

Operating Activities. Cash flows provided by operations increased $1.7 billion in the first three months of 2023 as compared to the year-ago period, primarily due to higher profitability as improvements in the demand for air travel continued.
Investing Activities. Cash flows used in investing activities increased $1.5 billion in the first three months of 2023 as compared to the year-ago period, primarily due to an increase in capital expenditures, which were approximately $1.8 billion and $0.4 billion for the three months ended March 31, 2023 and 2022, respectively. Capital expenditures for the three months ended March 31, 2023 were primarily attributable to the purchase of aircraft, aircraft improvements and advance deposits for future aircraft purchases.
Financing Activities. Significant financing events in the three months ended March 31, 2023 were as follows:
Debt, Finance Lease and Other Financing Liability Principal Payments. During the three months ended March 31, 2023 and 2022, the Company made payments for debt, finance leases, and other financing liabilities of $0.8 billion.
Debt and Other Financing Liabilities Issuances. During the three months ended March 31, 2023, United received and recorded, net of fees, $488 million from aircraft financings.
See Note 8 to the financial statements included in Part I, Item 1 of this report for additional information.

Credit Ratings. As of the filing date of this report, UAL and United had the following corporate credit ratings:

| S&P |  | Moody's |  | Fitch
UAL | BB- |  | Ba2 |  | B+
United | BB- |  | * |  | B+
*The credit agency does not issue corporate credit ratings for subsidiary entities.

These credit ratings are below investment grade levels; however, the Company has been able to secure financing with investment grade credit ratings for certain enhanced equipment trust certificates (EETCs), term loans and secured bond financings. Downgrades from these rating levels, among other things, could restrict the availability, or increase the cost, of future financing for the Company as well as affect the fair market value of existing debt. A rating reflects only the view of a rating agency and is not a recommendation to buy, sell or hold securities. Ratings can be revised upward or downward at any time by a rating agency if such rating agency decides that circumstances warrant such a change.
Commitments, Contingencies and Liquidity Matters. As described in the 2022 Form 10-K, the Company's liquidity may be adversely impacted by a variety of factors, including, but not limited to, pension funding obligations, reserve requirements associated with credit card processing agreements, guarantees, commitments and contingencies.
See the 2022 Form 10-K and Notes 6, 7 and 8 to the financial statements contained in Part I, Item 1 of this report for additional information.
CRITICAL ACCOUNTING POLICIES
See "Critical Accounting Policies" in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in the 2022 Form 10-K.
Supplemental Information
The Company evaluates its financial performance utilizing various GAAP and non-GAAP financial measures, including CASM-ex. The Company has provided CASM-ex, a non-GAAP financial measure, which is not calculated or presented in accordance with GAAP, as supplemental information and in addition to the financial measure that is calculated and presented in accordance with GAAP. Management believes that adjusting for special charges (credits) is useful to investors because special charges (credits) are not indicative of UAL's ongoing performance. Management also believes that excluding third-party business expenses, such as expenses associated with maintenance and ground handling for third parties from CASM, provides more meaningful disclosure because these expenses are not directly related to the Company's core business. Management also believes that excluding fuel costs from CASM is useful to investors because it provides an additional measure of management's performance excluding the effects of a significant cost item over which management has limited influence. Management also believes that excluding profit sharing from CASM allows investors to better understand and analyze the Company's operating cost performance and provides a more meaningful comparison of our core operating costs to the airline industry (due to losses, profit sharing was zero for the periods presented below).
Because this non-GAAP financial measure is not calculated in accordance with GAAP, it should not be considered superior to, and is not intended to be considered in isolation or as a substitute for, the related GAAP financial measure and may not be the same as or comparable to any similarly titled measures presented by other companies due to possible differences in method and in the items being adjusted. We encourage investors to review our financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure.
Below is a reconciliation of the non-GAAP financial measure provided in this report (CASM-ex) to the most directly comparable GAAP financial measure (CASM) for the three months ended March 31 (in cents):

| 2023 |  | 2022
CASM (GAAP) | 17.46 |  |  | 16.79 |
Fuel expense | 4.83 |  |  | 4.19 |
Third-party business expenses | 0.06 |  |  | 0.06 |
Special charges (credits) | 0.03 |  |  | (0.01) |
CASM-ex (Non-GAAP) | 12.54 |  |  | 12.55 |

All statements, other than those that relate solely to historical facts, are forward-looking statements.
Additionally, forward-looking statements include conditional statements and statements that identify uncertainties or trends, discuss the possible future effects of known trends or uncertainties, or that indicate that the future effects of known trends or uncertainties cannot be predicted, guaranteed or assured. All forward-looking statements in this report are based upon information available to us on the date of this report. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise, except as required by applicable law or regulation.
Our actual results could differ materially from these forward-looking statements due to numerous factors including, without limitation, the following: execution risks associated with our strategic operating plan; changes in our network strategy or other factors outside our control resulting in less economic aircraft orders, costs related to modification or termination of aircraft orders or entry into less favorable aircraft orders, as well as any inability to accept or integrate new aircraft into our fleet as planned; any failure to effectively manage, and receive anticipated benefits and returns from, acquisitions, divestitures, investments, joint ventures and other portfolio actions, as well as related costs or other issues, or related exposures to unknown liabilities or other issues or underperformance as compared to our expectations; the adverse impacts of the ongoing COVID-19 global pandemic on our business, operating results, financial condition and liquidity; adverse publicity, harm to our brand, reduced travel demand, potential tort liability and voluntary or mandatory operational restrictions as a result of an accident, catastrophe or incident involving us, our regional carriers, our codeshare partners or another airline; the highly competitive nature of the global airline industry and susceptibility of the industry to price discounting and changes in capacity, including as a result of alliances, joint business arrangements or other consolidations; our reliance on a limited number of suppliers to source a majority of our aircraft and certain parts, and the impact of any failure to obtain timely deliveries, additional equipment or support from any of these suppliers; disruptions to our regional network and United Express flights provided by third-party regional carriers; unfavorable economic and political conditions in the United States and globally; reliance on third-party service providers and the impact of any significant failure of these parties to perform as expected, or interruptions in our relationships with these providers or their provision of services; extended interruptions or disruptions in service at major airports where we operate and space, facility and infrastructure constraints at our hubs or other airports; geopolitical conflict, terrorist attacks or security events; any damage to our reputation or brand image; our reliance on technology and automated systems to operate our business and the impact of any significant failure or disruption of, or failure to effectively integrate and implement, the technology or systems; increasing privacy and data security obligations or a significant data breach; increased use of social media platforms by us, our employees and others; the impacts of union disputes, employee strikes or slowdowns, and other labor-related disruptions or regulatory compliance costs on our operations or financial performance; any failure to attract, train or retain skilled personnel, including our senior management team or other key employees; the monetary and operational costs of compliance with extensive government regulation of the airline industry; current or future litigation and regulatory actions, or failure to comply with the terms of any settlement, order or arrangement relating to these actions; costs, liabilities and risks associated with environmental regulation and climate change, including our climate goals; high and/or volatile fuel prices or significant disruptions in the supply of aircraft fuel; the impacts of our significant amount of financial leverage from fixed obligations and the impacts of insufficient liquidity on our financial condition and business; failure to comply with financial and other covenants governing our debt, including our MileagePlus® financing agreements; the impacts of the proposed phase out of the London interbank offer rate; limitations on our ability to use our net operating loss carryforwards and certain other tax attributes to offset future taxable income for U.S. federal income tax purposes; our failure to realize the full value of our intangible assets or our long-lived assets, causing us to record impairments; fluctuations in the price of our common stock; the impacts of seasonality and other factors associated with the airline industry; increases in insurance costs or inadequate insurance coverage and other risks and uncertainties set forth under Part I, Item 1A. Risk Factors, of the
30

Table of Contents |  |

2022 Form 10-K, and under "Economic and Market Factors" in Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report, as well as other risks and uncertainties set forth from time to time in the reports we file with the SEC.
The foregoing list sets forth many, but not all, of the factors that could impact our ability to achieve results described in any forward-looking statements. Investors should understand that it is not possible to predict or identify all such factors and should not consider this list to be a complete statement of all potential risks and uncertainties. It is routine for our internal projections and expectations to change as the year or each quarter in the year progresses, and therefore it should be clearly understood that the internal projections, beliefs and assumptions upon which we base our expectations may change. For instance, we regularly monitor future demand and booking trends and adjust capacity, as needed. As such, our actual flown capacity may differ materially from currently published flight schedules or current estimations.
