Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to our management. All statements other than statements of historical factors are “forward-looking statements” for purposes of these provisions. In some cases, you can identify forward-looking statements by terms such as “may,” “might,” “will,” “should,” “could,” “would,” “expect,” “intends,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “targets,” “predict,” “potential,” and similar expressions intended to identify forward-looking statements. Such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements. You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q, as well as our audited consolidated financial statements and related notes as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as filed with the SEC on February 23, 2022. This discussion contains forward-looking statements based upon current plans, expectations and beliefs involving risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth in Part II, Item 1A, “Risk Factors”, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other factors set forth in other parts of this Quarterly Report on Form 10-Q. Furthermore, such forward-looking statements speak only as of the date of this report. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

Summary Risk Factors

Our business is subject to a number of risks and uncertainties that may affect our business, results of operations and financial condition, or the trading price of our common stock or other securities. We are also subject to risks in relation to the proposed merger with Spirit Airlines, Inc. (“Spirit”). We caution the reader that these risk factors may not be exhaustive. We operate in a continually changing business environment, and new risks and uncertainties emerge from time to time. Management cannot predict such new risks and uncertainties, nor can it assess the extent to which any of the risk factors below or any such new risks and uncertainties, or any combination thereof, may impact our business. The risks identified below are more fully described in Part II, Item 1A. Risk Factors. Such factors include:

1. Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements have been prepared in accordance with the generally accepted accounting principles in the United States (“GAAP”) and include the accounts of Frontier Group Holdings, Inc. (“FGHI” or the “Company”) and its wholly-owned direct and indirect subsidiaries, including Frontier Airlines Holdings, Inc. (“FAH”) and Frontier Airlines, Inc. (“Frontier”). All wholly-owned subsidiaries are consolidated, with all intercompany transactions and balances being eliminated.

The Company is an ultra low-cost, low-fare airline headquartered in Denver, Colorado that offers flights throughout the United States and to select international destinations in the Americas, serving approximately 120 airports.

The Company is managed as a single business unit that primarily provides air transportation for passengers. Management has concluded there is only one reportable segment.

The accompanying condensed consolidated financial statements include the accounts of the Company and reflect all normal recurring adjustments which management believes are necessary to fairly present the financial position, results of operations and cash flows of the Company for the respective periods presented. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was filed with the SEC on February 23, 2022 (the “2021 Annual Report”).

The interim results reflected in the unaudited condensed consolidated financial statements are not necessarily indicative of the results that may be expected for other interim periods or for the full year. The air transportation business is subject to significant seasonal fluctuations and is volatile and highly affected by economic cycles and trends. In addition, the Company has continued to be impacted from the novel strain of coronavirus (“COVID-19”) pandemic during the three months ended March 31, 2022, as well as during the comparable period in 2021.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.

Initial Public Offering

On March 31, 2021, the Company’s registration statement on Form S-1 relating to the Company’s initial public offering (“IPO”) was declared effective by the SEC, and the Company’s common stock began trading on the NASDAQ Global Select Market on April 1, 2021 under the symbol “ULCC”.

2. Impact of COVID-19

Impact of the COVID-19 Pandemic

Beginning in March 2020, the rapid spread of COVID-19, along with government-mandated restrictions on travel, required stay-in-place orders, and other social distancing measures, resulted in the decline in demand for air travel which continued to have a material adverse effect on the Company’s business and results of operations for the three months ended March 31, 2022 and the comparable prior year period. Although the Company has seen significant recovery of demand through the quarter ended March 31, 2022 as compared to the corresponding prior year period, the Company is unable to predict the future spread and impact of COVID-19, including future variants of the virus such as the recent Omicron variant and its subvariants, or the efficacy and adherence rates of vaccines and other therapeutics and the resulting measures that may be introduced by governments or other parties and what impact those measures may have on the demand for air travel.

Beginning in December 2020, the Food and Drug Administration issued emergency use authorizations for various vaccines for COVID-19. Widespread distribution of the vaccines has led to increased confidence in travel, particularly in the domestic leisure market on which the Company’s business is focused. While the Company has experienced a meaningful increase in passenger volumes, as well as bookings, since the vaccines became widely available, demand recovery may continue to be hampered as a result of new variants or subvariants of the virus. The Company continues to closely monitor the COVID-19 pandemic and the need to adjust capacity as well as deploy other operational and cost-control measures, as necessary, to preserve short-term liquidity needs and ensure long-term viability of the Company and its strategies. Any anticipated adjustments to capacity and other cost savings initiatives implemented by the Company may vary from actual demand and capacity needs.

The Company continues to monitor covenant compliance with various parties, including, but not limited to, its lenders and credit card processors, and as of March 31, 2022, and through the date of this report, the Company is in compliance with all of its covenants, except the Company has obtained a waiver of relief for the covenant provisions through the second quarter of 2022 related to one of its credit card processors that represents less than 10% of total revenues, which may require future waivers or an amendment to the existing covenants to reflect any additional COVID-19 pandemic impacts.

COVID-19 Relief Funding

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) became law on March 27, 2020 and includes various provisions to protect the U.S. airline industry, its employees, and many other stakeholders. The CARES Act is a relief package intended to assist many aspects of the American economy, including providing the airline industry with up to $25 billion for a Payroll Support Program (the “PSP”) to be used for employee wages, salaries, and benefits and up to $25 billion in loans. Through 2020 and 2021, the Company participated in the PSP, as well as the second Payroll Support Program (“PSP2”) and the third Payroll Support Program (“PSP3,” and together with the PSP and the PSP2, the “PSPs”) offered by the U.S. Department of the Treasury (the “Treasury”), each of which included both a grant and an unsecured 10-year, low-interest promissory note. The grants were recognized within the Company’s condensed consolidated statements of operations over the periods they were intended to support payroll. See Note 7 for further information on the promissory notes entered into with the Treasury as a result of participation in the payroll support programs (collectively, the “PSP Promissory Notes”) and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—COVID-19 Relief Funding” in our 2021 Annual Report for additional detail on the CARES Act and the PSPs.

On September 28, 2020, the Company entered into a loan agreement with the Treasury for a term loan facility of up to $574 million pursuant to the secured loan program established under the CARES Act (the “Treasury Loan”). As of December 31, 2021, the Company had borrowed $150 million under the Treasury Loan, for which the right to draw any further funds lapsed in May 2021. On February 2, 2022, the Company repaid the Treasury Loan which included the $150 million principal balance along with accrued interest and associated fees of $1 million.

(unaudited)

On January 15, 2021, as a result of the Consolidated Appropriations Act, 2021 (the “PSP Extension Law”), which extended the PSP provisions of the CARES Act, the Company entered into an agreement with the Treasury for installment funding under the PSP2, under which the Company received $161 million, comprised of a $143 million grant (the “PSP2 Grant”) for the continuation of payroll support from the date of the agreement through March 31, 2021, and an $18 million unsecured 10-year, low-interest loan (the “PSP2 Promissory Note”). During the three months ended March 31, 2021, $140 million of PSP2 proceeds were received and the remaining $21 million was received during the second quarter of 2021. The Company recognized $125 million of PSP2 Grant proceeds, net of deferred financing costs, during the three months ended March 31, 2021 within CARES Act credits in the Company’s condensed consolidated statements of operations and $3 million was deferred until the second quarter of 2021. The Company received $12 million of the PSP2 Promissory Note as of March 31, 2021.

In connection with the Company’s participation in the PSPs and the Treasury Loan, the Company has been and will continue to be subject to certain restrictions and limitations, including, but not limited to:

•restrictions on repurchases of equity securities listed on a national securities exchange or payment of dividends until February 2, 2023;

•requirements to maintain certain levels of scheduled services through March 31, 2022 (including to destinations where there may currently be significantly reduced or no demand);

•a prohibition on involuntary terminations or furloughs of employees (except for health, disability, cause, or certain disciplinary reasons) through September 30, 2021;

•a prohibition on reducing the salary, wages or benefits of employees (other than executive officers or independent contractors, or as otherwise permitted under the terms of the PSPs) through September 30, 2021;

•limits on certain executive compensation, including limiting pay increases and severance pay or other benefits upon terminations, until April 1, 2023;

•limitations on the use of the grant funds exclusively for the continuation of payment of employee wages, salaries and benefits; and

•additional reporting and recordkeeping requirements.

As part of the PSP Promissory Notes and the Treasury Loan, the Company issued to the Treasury warrants to purchase 3,117,940 shares of FGHI common stock at a weighted average price of $6.95 per share. The initial fair value of these warrants upon issuance was treated as a loan discount, which reduced the carrying value of the related debt, and is amortized utilizing the effective interest method as interest expense in the Company’s condensed consolidated statements of operations over the term of each loan. These awards were originally classified as liability-based awards within other current liabilities on the condensed consolidated balance sheets, with periodic mark to market remeasurements being included in interest expense in the Company’s condensed consolidated statements of operations given the Company only had the option of settling in cash prior to being publicly traded. As a result of the IPO, the Company has the intent and ability to settle the warrants issued to the Treasury in shares and as a result, as of April 6, 2021, the Company reclassified the warrant liability to additional paid-in capital on the condensed consolidated balance sheet and is no longer required to mark to market the warrants. The Company recorded no mark to market adjustments during the three months ended March 31, 2022, and recorded $20 million during the three months ended March 31, 2021, to interest expense within the Company’s condensed consolidated statements of operations. The Treasury has not exercised any warrants as of March 31, 2022.

The CARES Act also provided for an employee retention credit (“CARES Employee Retention Credit”), which is a refundable tax credit against certain employment taxes that the Company qualified for beginning on April 1, 2020. In December 2020, the CARES Employee Retention Credit program was extended and enhanced through June 30, 2021. The American Rescue Plan Act, enacted on March 11, 2021, further extended the availability of the CARES Employee Retention Credit through December 31, 2021. After the first quarter of 2021, the Company did not qualify for any additional CARES Employee Retention Credits. During the three months ended March 31, 2021, the Company recognized $11 million related to the CARES Employee Retention Credit within CARES Act credits in the Company’s condensed consolidated statements of operations.

3. Revenue Recognition

As of December 31, 2021, the Company’s current air traffic liability balance was $273 million. During the three months ended March 31, 2022, 67% of the air traffic liability as of December 31, 2021 has been recognized as passenger revenue within the condensed consolidated statements of operations. As of March 31, 2022, the Company’s current air traffic liability is $363 million, of which $47 million is related to customer rights to book future travel, which either expire within 3 or 12 months after issuance if not redeemed by the customer. The amounts expected not to be redeemed are recognized over the historical pattern of rights exercised by customers to fare revenues in passenger revenues within the condensed consolidated statements of operations.

During the three months ended March 31, 2022 and 2021, the Company recognized $22 million and $10 million of revenue, respectively, in passenger revenues within the condensed consolidated statements of operations, primarily related to expected and actual expiration of customer rights to book future travel.

Frequent Flyer Program

The Company’s Frontier Miles frequent flyer program provides frequent flyer travel awards to program members based on accumulated mileage credits. Mileage credits are generally accumulated as a result of travel, purchases using the co-branded credit card and purchases from other participating partners.

The Company defers revenue for mileage credits earned by passengers under its Frontier Miles program based on the equivalent ticket value a passenger receives by redeeming mileage credits for a ticket rather than paying cash.

Mileage credits are also sold to participating companies, including credit card companies and other third parties. Sales to credit card companies include multiple promised goods and services, which the Company evaluates to determine whether they represent performance obligations. The Company determined these arrangements have three separate performance obligations: (i) mileage credits to be awarded, (ii) licensing of brand and access to member lists and (iii) advertising and marketing efforts. Total arrangement consideration is allocated to each performance obligation on the basis of the deliverables relative standalone selling price. For mileage credits, the Company considers a number of entity-specific factors when developing the best estimate of the standalone selling price, including the number of mileage credits needed to redeem an award, average fare of comparable segments, breakage and restrictions. For licensing of brand and access to member lists, the Company considers both market-specific factors and entity-specific factors, including general profit margins realized in the marketplace and industry, brand power, market royalty rates and size of customer base. For the advertising and marketing performance obligation, the Company considers market-specific factors and entity-specific factors, including the Company’s internal costs of providing services, volume of marketing efforts and overall advertising plan.

Consideration allocated based on the relative standalone selling price to both the brand licensing and access to member lists and advertising and marketing elements is recognized as other revenue in the Company’s condensed consolidated statements of operations over time as mileage credits are delivered. The consideration allocated to the transportation portion of these mileage credit sales is deferred and recognized as a component of passenger revenue in the Company’s condensed consolidated statements of operations at the time of travel for mileage credits redeemed. Mileage credits that the Company estimates are not likely to be redeemed are subject to breakage and are recognized as a portion of passenger revenues in the Company’s condensed consolidated statements of operations in proportion to the pattern of rights exercised by customers. Management uses statistical models to estimate breakage based on historical redemption patterns. A change in assumptions as to the period over which mileage credits are expected to be redeemed, the actual redemption activity for mileage credits or the estimated fair value of mileage credits expected to be redeemed could have an impact on revenues in the year in which the change occurs and in future years. Redemptions are allocated between sold and flown mileage credits based on historical patterns.

As a result of the reduction in demand due to the COVID-19 pandemic, the Company extended the expiration dates of mileage credits issued under its frequent flyer program.

The Company has a credit card affinity agreement with its credit card partner Barclays Bank Delaware (“Barclays”) through 2029, which provides for joint marketing, grants certain benefits to co-branded credit card holders and allows Barclays to market using the Company’s customer database. Cardholders earn mileage credits under the Frontier Miles program and the Company sells mileage credits at agreed-upon rates to Barclays and earns fees from Barclays for the acquisition, retention and use of the co-branded credit card by consumers.

5. Financial Derivative Instruments and Risk Management

The Company is exposed to variability in jet fuel prices. Aircraft fuel is one of the Company’s largest operating expenses. Increases in jet fuel prices may adversely impact its financial performance, operating cash flow and financial position. As part of its risk management program, the Company may enter into derivative contracts in order to limit exposure to the fluctuations in jet fuel prices. During the three months ended March 31, 2022 and 2021, the Company did not enter into fuel hedges and therefore, paid no upfront premiums for fuel hedges. As of March 31, 2022 and December 31, 2021, there were no fuel hedges outstanding.

Additionally, the Company may be exposed to interest rate risk through aircraft lease contracts for the time period between agreement of terms and commencement of the lease, when portions of rental payments can be adjusted and become fixed based on the seven- or nine-year swap rate. As part of its risk management program, the Company may enter into contracts in order to limit the exposure to fluctuations in interest rates. During the three months ended March 31, 2022 and 2021, the Company did not enter into any swaps and therefore, paid no upfront premiums for options. As of March 31, 2022 and December 31, 2021, the Company had no interest rate hedges outstanding.

The Company formally designates and accounts for derivative instruments that meet established accounting criteria under ASC 815, Derivatives and Hedging, as cash flow hedges. For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative instruments is recorded in accumulated other comprehensive income/loss (“AOCI/L”), a component of stockholders’ equity on the condensed consolidated balance sheets. The Company recognizes the associated gains or losses deferred in AOCI/L as well as the amounts that are paid or received in connection with the purchase or sale of fuel-related financial derivative instruments (i.e., premium costs of option contracts) as a component of aircraft fuel expense within the condensed consolidated statements of operations in the period that the jet fuel subject to hedging is consumed. For interest rate derivatives, the Company recognizes the associated gains or losses deferred in AOCI/L as well as amounts that are paid or received in connection with the purchase or sale of interest rate derivative instruments (i.e., premium costs of swaption contracts) as a component of aircraft rent expense within the condensed consolidated statements of operations over the period of the related aircraft lease. The assets and liabilities associated with the Company’s fuel and interest rate derivative instruments are presented on a gross basis and include upfront premiums paid. These assets and liabilities are recorded as a component of other current assets and other current liabilities, respectively, on the Company’s condensed consolidated balance sheets. The Company does not enter into derivative instruments for speculative purposes.

As of March 31, 2022 and December 31, 2021, $10 million is included in AOCI/L related to interest rate hedging instruments that is expected to be reclassified into aircraft rent within the condensed consolidated statements of operations over the aircraft lease term of the hedging instrument.

(a)The Company, through an affiliate, entered into the pre-delivery payment (“PDP”) facility with Citibank, N.A. in December 2014 (“PDP Financing Facility”). The PDP Financing Facility is collateralized by the Company’s purchase agreement for Airbus A320neo and A321neo aircraft deliveries through the term of the facility (see Note 10). In December 2020, the PDP Financing Facility was amended and restated to reduce the commitment of Citibank, N.A., as initial lender, to $150 million, remove the ability to draw further unsecured borrowings and to provide collateral for the borrowings not secured by aircraft outstanding as of that date. In May 2021, the Company amended the facility to increase the total available capacity to $200 million and expanded the number of financial institution participants as lenders. In December 2021, the facility was amended and restated to extend the availability of the facility through December 2024 to include additional 2023 and 2024 aircraft deliveries, and in March 2022 the facility was further amended to re-align the PDP Financing Facility with the updated future aircraft deliveries.

Interest is paid every 90 days based on a three-month LIBOR plus a margin for each individual tranche. The PDP Financing Facility consists of separate loans for each PDP aircraft. Each separate loan matures upon the earlier of (i) delivery of that aircraft to the Company by Airbus, (ii) the date one month following the last day of the scheduled delivery month of such aircraft and (iii) if there is a delay in delivery of aircraft, depending on the cause of the delivery delay, up to six months following the last day of the scheduled delivery month of such aircraft. The PDP Financing Facility will be repaid periodically according to the preceding sentence with the last scheduled delivery of aircraft contemplated in the PDP Financing Facility, as currently in effect, expected to be in the fourth quarter of 2024.

(b)On September 28, 2020, the Company entered into the Treasury Loan with the Treasury for a term loan facility of up to $574 million, and had borrowed $150 million under the loan as of December 31, 2021. On February 2, 2022, the Company repaid the Treasury Loan in full, along with accrued interest and associated fees of $1 million. Additionally, the Company recognized a $7 million loss on the extinguishment of debt for the three months ended March 31, 2022 from the write-off of unamortized deferred financing costs associated with the loan.

repayment terminated the loan agreement with the Treasury and unencumbered the Company’s co-branded credit card program and related brand assets that secured the Treasury Loan.

(c)Represents a note with a commercial bank related to the Company’s headquarters building. Under the terms of the agreement, the Company will repay the outstanding principal balance in quarterly payments beginning in January 2022 until the maturity date in December 2023. On the maturity date, one final balloon payment will be made to cover all unpaid principal, accrued unpaid interest and other amounts due. The interest rate of one-month LIBOR plus a margin is payable monthly.

(d)On April 30, 2020, the Company executed a promissory note under the PSP agreement with the Treasury from which the Company received a $33 million unsecured 10-year, low-interest loan (the “PSP Promissory Note”). Subsequently, the Company entered into the PSP2 with the Treasury in January 2021 and the PSP3 with the Treasury in April 2021, from which the Company received an additional $18 million and $15 million of proceeds, respectively, evidenced by promissory notes with the same terms as the original PSP Promissory Note. The PSP Promissory Notes include an annual interest rate of 1.00% for the first five years and the Secured Overnight Financing Rate ("SOFR") plus 2.00% in the final five years. The loans can be prepaid at par at any time without incurring a penalty.

(e)The Company entered into an agreement with Barclays in 2003 to provide for joint marketing, grant certain benefits to co-branded credit card holders (“Cardholders”), and allow Barclays to market using the Company’s customer database. Cardholders earn mileage credits under the Frontier Miles program and the Company sells mileage credits at agreed-upon rates to Barclays and earns fees from Barclays for the acquisition, retention and use of the co-branded credit card by consumers. In addition, Barclays will pre-purchase miles if the Company meets certain conditions precedent. On September 15, 2020 the Company entered into a new agreement with Barclays to amend and extend the agreement to 2029. The pre-purchased miles facility amount is to be reset on January 15 of each calendar year through, and including, January 15, 2028 based on the aggregate amount of fees payable by Barclays to the Company on a calendar year basis, up to an aggregate maximum facility amount of $200 million. Per the terms of the Treasury Loan, the facility amount could not be extended above $15 million until full extinguishment of the Treasury Loan, which occurred in February 2022, and, as a result, the Company borrowed an additional $56 million in the first quarter of 2022. The Company pays interest on a monthly basis, which is based on a one-month LIBOR plus a margin. Beginning March 31, 2028, the facility is scheduled to be repaid in 12 equal monthly installments.

Cash payments for interest related to debt was $2 million and $1 million for the three months ended March 31, 2022 and 2021, respectively.

The Company has issued standby letters of credit and surety bonds to various airport authorities and vendors that are collateralized by restricted cash and as of March 31, 2022 and December 31, 2021, the Company did not have any outstanding letters of credit that were drawn upon.

As of March 31, 2022, future maturities of debt are payable as follows (in millions):

8. Operating Leases

The Company leases property and equipment under operating leases. For leases with initial terms greater than 12 months, the related operating lease right-of-use asset and corresponding operating lease liability are recorded at the present value of lease payments over the term on the Company’s condensed consolidated balance sheets. Some leases include rental escalation clauses, renewal options, termination options, and/or other items that cause variability that are factored into the determination of lease payments when appropriate. The Company does not separate lease and non-lease components of contracts, except for certain flight training equipment, for which consideration is allocated between lease and non-lease components.

Aircraft

As of March 31, 2022, the Company leased 112 aircraft with remaining terms ranging from one month to twelve years, all of which are under operating leases and are included within right-of-use asset and lease liabilities on the Company’s condensed consolidated balance sheets. In addition, as of March 31, 2022, the Company leased 21 spare engines, which are all under operating leases, with the remaining terms ranging from one month to twelve years. As of March 31, 2022, the lease rates for seven of the engines depend on usage-based metrics which are variable and as such, these leases are not recorded on the Company’s condensed consolidated balance sheets as a right-of-use asset and lease liability.

During the three months ended March 31, 2022 and 2021, the Company executed sale-leaseback transactions with third-party lessors for two and three new Airbus A320 family aircraft, respectively. Additionally, the Company did not complete a sale-leaseback transaction for any engines during the three months ended March 31, 2022, and completed a sale-leaseback transaction for one engine during the three months ended March 31, 2021. All of the leases from sale-leaseback transactions have been accounted for as operating leases. The Company recognized net sale-leaseback gains of $7 million and $15 million during the three months ended March 31, 2022 and 2021, respectively, which are included as a component of other operating expenses within the condensed consolidated statements of operations.

In May 2021, the Company entered into an early termination and buyout agreement with one of its lessors for six aircraft previously owned by the Company, which stipulated that four A319 aircraft originally scheduled to be returned in December 2021 would be returned during the second and third quarters of 2021 and the two A320ceo aircraft would return as scheduled during the fourth quarter of 2021. The early returns of these aircraft retired the remaining A319 aircraft in the Company’s fleet. As a result of this early termination and buyout arrangement, the Company recorded a $6 million charge included as a component of rent expense within the condensed consolidated statement of operations for the three months ended March 31, 2021, related to the accelerated rent and lease return obligations of which $4 million was related to the A319 aircraft returning in the second quarter.

Aircraft Rent Expense and Maintenance Obligations

During the three months ended March 31, 2022 and 2021, aircraft rent expense was $128 million and $138 million, respectively. Aircraft rent expense includes supplemental rent, which is made up of maintenance reserves paid or to be paid that are not probable of being reimbursed and probable lease return condition obligations. Supplemental rent expense, which includes payments for maintenance-related reserves that were deemed non-recoverable and any impact from changes in estimates, was less than $1 million and $1 million for the three months ended March 31, 2022 and 2021, respectively. The portion of supplemental rent expense related to probable lease return condition obligations was $15 million and $14 million for three months ended March 31, 2022 and 2021, respectively.

Additionally, certain of the Company’s aircraft lease agreements require the Company to pay maintenance reserves to aircraft lessors to be held as collateral in advance of the Company’s required performance of major maintenance activities. As of March 31, 2022 and December 31, 2021, the Company had aircraft maintenance deposits that are expected to be recoverable of $114 million and $108 million, respectively, on the Company’s condensed consolidated balance sheets, of which $12 million and $10 million, respectively, are included in accounts receivable, net on the condensed consolidated balance sheet as the eligible maintenance has been performed. The remaining $102 million and $98 million are included within aircraft maintenance deposits on the condensed consolidated balance sheets as of March 31, 2022 and December 31, 2021, respectively.

A majority of these maintenance reserve payments are calculated based on a utilization measure, such as flight hours or cycles. Maintenance reserves collateralize the lessor for maintenance time run off the aircraft until the completion of the maintenance of the aircraft. As of March 31, 2022, fixed maintenance reserve payments for aircraft and spare engines, including estimated amounts for contractual price escalations, are expected to be $2

million for the remainder of 2022 and $3 million per year for the years 2023 through 2025, $4 million for 2026 and $9 million thereafter before consideration of reimbursements.

Airport Facilities

The Company’s facility leases are primarily for space at approximately 120 airports that are primarily located in the United States. These leases are classified as operating leases and reflect the use of airport terminals, ticket counters, office space, and maintenance facilities. Generally, this space is leased from government agencies that control the use of the airport. The majority of these leases are short-term in nature and renew on an evergreen basis. For these leases, the contractual term is used as the lease term. As of March 31, 2022, the remaining lease terms vary from one month to eleven years. At the majority of the U.S. airports, the lease rates depend on airport operating costs or use of the facilities and are reset at least annually, and because of the variable nature of the rates, these leases are not recorded on the condensed consolidated balance sheets as a right-of-use assets and lease liabilities.

In May 2022, the Company entered into a 10-year airport use and lease agreement with the City and County of Denver for the Company’s operations at Denver International Airport which includes a new ground-level boarding facility and 14 accompanying gates.

Other Ground Property and Equipment

The Company leases certain other assets such as flight training equipment, building space, and various other equipment. Certain of the Company’s leases for other assets are deemed to contain fixed rental payments and, as such, are classified as operating leases and are recorded on the condensed consolidated balance sheets as a right-of-use asset and liability. The remaining lease terms range from one month to seven years as of March 31, 2022.

Lessor Concessions

In response to the COVID-19 pandemic, beginning in 2020, the Company was granted payment deferrals on leases included in the Company’s right-of-use assets for certain aircraft and engines from lessors along with airport facilities and other vendors that are not included in the Company’s right-of-use assets. As these deferred payments are made, the Company will recognize the deferred payments in aircraft rent or station operations, as applicable, in the condensed consolidated statements of operations. There were no deferrals or payments, and therefore no impact to aircraft rent or station operations within the condensed consolidated statements of operations, for the three months ended March 31, 2022. The deferrals for three months ended March 31, 2021 decreased operating cash flows and unfavorably impacted the Company’s results of operations by $11 million, including a $19 million unfavorable impact to aircraft rent and an $8 million favorable impact to station operations. As of March 31, 2022, the Company had paid back all of its aircraft rent deferrals, and had $11 million in station deferrals which will be recognized to station operations within the condensed consolidated statements of operations in future periods as the deferrals are repaid.

During the three months ended March 31, 2022 and 2021, the Company acquired, through new operating leases, operating lease assets totaling $61 million and $120 million, respectively, which are included in operating lease right-of-use assets on the condensed consolidated balance sheets. During the three months ended March 31, 2022 and 2021, the Company paid cash of $117 million and $108 million, respectively, for amounts included in the measurement of lease liabilities.

9. Stock-Based Compensation and Stockholders’ Equity

During each of the three months ended March 31, 2022 and 2021, the Company recognized $3 million in stock-based compensation expense, which is included as a component of salaries, wages and benefits within the condensed consolidated statements of operations.

Stock Options and Restricted Awards

In April 2014, the Company approved the 2014 Equity Incentive Plan (the “2014 Plan”). Under the terms of the 2014 Plan, 38 million shares of FGHI common stock were reserved for issuance. Concurrently with the Company’s IPO on April 1, 2021, the Company approved the 2021 Incentive Award Plan (the “2021 Plan”), which reserved 7 million shares of FGHI common stock for future issuance of stock-based compensation awards. Additionally, the 2014 Plan terminated and the 11 million awards issued from the 2014 Plan that were outstanding as of the IPO were retained for any subsequent exercise or vesting of such awards and no further grants will be made from the 2014 Plan. Any shares that are subsequently forfeited from the 2014 Plan will become available for future issuances under the 2021 Plan. Additional shares become available for issuance under the 2021 Plan based on an annual increase on the first day of each fiscal year beginning in 2022 and ending in 2031, equal to the lesser of (i) one percent (1%) of the shares of stock outstanding on the last day of the immediately preceding fiscal year and (ii) such smaller number of shares of stock as determined by the Company’s board of directors; provided, however, that no more than 30 million shares of stock may be issued upon the exercise of incentive stock options. On January 1, 2022, 2,170,650 shares were added to the 2021 Plan as a result of the annual increase.

There were no stock options granted during the three months ended March 31, 2022. During the three months ended March 31, 2022, 34,461 vested stock options were exercised with a weighted average exercise price of $6.28 per share. As of March 31, 2022, the weighted average exercise price of outstanding options was $1.97.

During the three months ended March 31, 2022, 1,009,091 restricted stock units were issued with a weighted average grant date fair value of $12.60 per share. During the three months ended March 31, 2022, 676,146 restricted stock units vested, of which 275,822 restricted stock units were withheld to cover employee taxes with a weighted average grant date fair value of $12.17 and $12.18 per share, respectively.

Liability-Classified Awards

On December 3, 2013, to give effect to the reorganization of the Company’s corporate structure, an agreement was reached to amend and restate a phantom equity agreement with the Company’s pilots. Under the terms of this agreement, when an amendment to the underlying collective bargaining agreement was approved, the Company’s pilots employed in June 2011, (the “Participating Pilots”), through their agent, FAPAInvest, LLC, received phantom equity units. Each unit represented the right to receive common stock or cash in connection with certain events, including a qualifying initial public offering, such stock to be distributed or cash paid to the Participating Pilots in 2020 and 2022 based on a predetermined formula. In accordance with the amended and restated phantom equity agreement, the obligation became fixed as of December 31, 2019 and was no longer subject to valuation adjustments. As of December 31, 2021, the remaining liability was $26 million and presented within other current liabilities on the Company’s condensed consolidated balance sheet. During the three months ended March 31, 2022 the $26 million was fully paid.

Stockholders’ Equity

As of March 31, 2022 and December 31, 2021, the Company has authorized common stock (voting), common stock (non-voting) and preferred stock of 750,000,000, 150,000,000 and 10,000,000 shares, respectively, of which only common stock (voting) were issued and outstanding. All classes of equity have a par value of $0.001 per share.

10. Commitments and Contingencies

Flight Equipment Commitments

As of March 31, 2022, the Company’s firm aircraft and engine orders consisted of the following:


	A320neo	A321neo	Total Aircraft	Engines
Year Ending
Remainder of 2022	7	5	12	5
2023	—	21	21	2
2024	—	24	24	2
2025	17	13	30	3
2026	19	22	41	3
Thereafter	31	73	104	6
Total	74	158	232	21

During December 2017, the Company entered into an amendment to the previously existing master purchase agreement with Airbus. Pursuant to this amendment and subsequent amendments, the Company has a commitment to purchase an incremental 67 A320neo and 67 A321neo aircraft (“incremental aircraft”) which were originally scheduled to be delivered through 2026, and further extended through 2028. In November 2021, the Company entered into an amendment with Airbus to add an additional 91 A321neo aircraft (“supplemental aircraft”) to the committed purchase agreement. These supplemental aircraft are expected to be delivered starting in 2023 and continuing through 2029, and are reflected in the table above. The Company, at its option, has the right to convert 18 A320neo aircraft to A321XLR aircraft. The conversion right is available until December 31, 2022 and is not reflected in the table above as this option has not been exercised. The Company’s agreements with Airbus provide for, among other things, varying purchase incentives, which have been allocated proportionally and are accounted for as an offsetting reduction to the cost of the backlog aircraft and increase to the cost of the incremental aircraft. As a result, cash paid for backlog aircraft will be more than the associated capitalized cost of the aircraft and results in the recognition of a deferred purchase incentive within other assets on the condensed consolidated balance sheets,

which will ultimately be offset by the lower cash payments in connection with the purchase of the incremental aircraft.

As of March 31, 2022, purchase commitments for these aircraft and engines, including estimated amounts for contractual price escalations and PDPs, were approximately $681 million for the remainder of 2022, $1,215 million in 2023, $1,450 million in 2024, $1,755 million in 2025, $2,346 million in 2026 and $6,218 million thereafter.

During July 2021, the Company signed a letter of intent with two of its leasing partners to add ten additional A321neo aircraft through direct leases, with deliveries beginning in the second half of 2022 and continuing into the first half of 2023. As of March 31, 2022, the Company has entered into a signed direct lease agreement for seven of the additional aircraft, while the remaining three are covered under a non-binding letter of intent. None of these ten aircraft that will be acquired through direct leases are reflected in the table above given these are not committed purchase agreements.

Litigation and Other Contingencies

On March 12, 2021, the DOT advised the Company that it was in receipt of information indicating that the Company had failed to comply with certain DOT consumer protection requirements relating to consumer refund and credit practices and requested that the Company provide certain information to the DOT. The original DOT request for information and subsequent correspondence and requests have been focused on the Company’s refund practices on Company initiated flight cancellations and/or significant schedule changes in flights as a result of the COVID-19 pandemic. The Company is fully cooperating with the DOT request and the review of this matter is still in process.

The Company is subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. The Company regularly evaluates the status of such matters to assess whether a loss is probable and reasonably estimable in determining whether an accrual is appropriate. Furthermore, in determining whether disclosure is appropriate, the Company evaluates each matter to assess if there is at least a reasonable possibility that a loss or additional losses may have been incurred and whether an estimate of possible loss or range of loss can be made. The Company believes the ultimate outcome of such lawsuits, proceedings, and reviews will not, individually or in the aggregate, have a material adverse effect on its condensed consolidated financial position, liquidity, or results of operations and that the Company’s current accruals cover matters where loss is deemed probable and can be reasonably estimated.

The ultimate outcome of legal actions is unpredictable and can be subject to significant uncertainties, and it is difficult to determine whether any loss is probable or even possible. Additionally, it is also difficult to estimate the amount of loss and there may be matters for which a loss is probable or reasonably possible but not currently estimable. Thus, actual losses may be in excess of any recorded liability or the range of reasonably possible loss.

__________________

(a)The Company’s collective bargaining agreements with its dispatchers and material specialists, represented by TWU and IBT, respectively, were amendable as of March 31, 2022 and negotiations are ongoing, however, each agreement is operating under its current arrangement until an amendment has been reached.

The Company is self-insured for health care claims, subject to a stop-loss policy, for eligible participating employees and qualified dependent medical and dental claims, subject to deductibles and limitations. The Company’s liabilities for claims incurred but not reported are determined based on an estimate of the ultimate aggregate liability for claims incurred. The estimate is calculated from actual claim rates and adjusted periodically as necessary. The Company has accrued $4 million and $5 million for health care claims including those estimated to be incurred but not yet paid as of March 31, 2022 and December 31, 2021, respectively, which is included as a component of other current liabilities on the condensed consolidated balance sheets.

General Indemnifications

The Company has various leases with respect to real property as well as various agreements among airlines relating to fuel consortia or fuel farms at airports. Under some of these contracts, the Company is party to joint and several liability regarding environmental damages. Under others, where the Company is a member of an LLC or other entity that contracts directly with the airport operator, liabilities are borne through the fuel consortia structure.

The Company’s aircraft, services, equipment lease and sale and financing agreements typically contain provisions requiring us, as the lessee, obligor or recipient of services, to indemnify the other parties to those agreements, including certain of those parties’ related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or such other equipment. The Company believes that its insurance would cover most of its exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft, services, equipment lease and sale and financing agreements described above.

Certain of the Company’s aircraft and other financing transactions include provisions that require payments to preserve an expected economic return to the lenders if that economic return is diminished due to certain changes in law or regulations. In certain of these financing transactions and other agreements, the Company also bears the risk of certain changes in tax laws that would subject payments to non-U.S. entities to withholding taxes.

Certain of these indemnities survive the length of the related financing or lease. The Company cannot reasonably estimate the potential future payments under the indemnities and related provisions described above because it cannot predict (i) when and under what circumstances these provisions may be triggered, and (ii) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.

11. Net Earnings (Loss) per Share

Basic and diluted earnings (loss) per share are computed pursuant to the two-class method. Under the two-class method, the Company attributes net income to common stock and other participating rights (including those with vested share-based awards). Basic net earnings per share is calculated by taking net income, less earnings allocated to participating rights, divided by the basic weighted average common stock outstanding. Net loss per share is calculated by taking net loss divided by basic weighted average common stock outstanding as participating rights do not share in losses. In accordance with the two-class method, diluted net earnings per share is calculated using the more dilutive impact of the treasury-stock method or from reducing net income for the earnings allocated to participating rights. The following table sets forth the computation of net earnings (loss) per share on a basic and diluted basis pursuant to the two-class method for the periods indicated (in millions, except for share and per share data):


	Three Months Ended March 31,
		2022		2021
Basic:
Net income (loss)		$	(121)	$	(91)
Less: net income attributable to participating rights		—		—
Net income (loss) attributable to common stockholders		$	(121)	$	(91)
Weighted average common shares outstanding, basic		217,264,414		199,482,701
Net earnings (loss) per share, basic		$	(0.56)	$	(0.46)
Diluted:
Net income (loss)		$	(121)	$	(91)
Less: net income attributable to participating rights		—		—
Net income (loss) attributable to common stockholders		$	(121)	$	(91)
Weighted average common shares outstanding, basic		217,264,414		199,482,701
Effect of dilutive potential common shares		—		—
Weighted average common shares outstanding, diluted		217,264,414		199,482,701
Net earnings (loss) per share, diluted		$	(0.56)	$	(0.46)

Due to the net losses incurred during the three months ended March 31, 2022 and 2021, diluted weighted average shares outstanding are equal to basic weighted average shares outstanding given that the effect of all equity awards is anti-dilutive.

12. Fair Value Measurements

Under ASC 820, Fair Value Measurements and Disclosures, disclosures relating to how fair value is determined for assets and liabilities are required, and a hierarchy for which these assets and liabilities must be grouped is established, based on significant levels of inputs, as follows:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

FRONTIER GROUP HOLDINGS, INC.

Notes to Condensed Consolidated Financial Statements (Continued)

(unaudited)

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes several valuation techniques in order to assess the fair value of its financial assets and liabilities.

Cash, Cash Equivalents and Restricted Cash

Cash, cash equivalents and restricted cash are comprised of liquid money market funds, time deposits and cash, and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions. Cash, cash equivalents and restricted cash are carried at cost, which management believes approximates fair value.

Debt

The estimated fair value of the Company’s debt agreements has been determined to be Level 3 measurement, as certain inputs used to determine the fair value of these agreements are unobservable. The Company utilizes a discounted cash flow method to estimate the fair value of the Level 3 long-term debt.

The carrying amounts and estimated fair values of the Company’s debt are as follows (in millions):


	March 31, 2022				December 31, 2021
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
Secured debt:
Pre-delivery credit facility	$	200	$	201	$	174	$	175
Treasury Loan	—		—		150		156
Floating rate building note	18		18		18		19
Unsecured debt:
PSP Promissory Notes	66		55		66		58
Affinity card advance purchase of mileage credits	71		67		15		14
Total debt	$	355	$	341	$	423	$	422

The tables below present disclosures about the fair value of assets and liabilities measured at fair value on a recurring basis in the Company’s condensed consolidated financial statements (in millions):



	Fair Value Measurements as of March 31, 2022
	Total		Level 1		Level 2		Level 3
Cash and cash equivalents	$	727	$	727	$	—	$	—


	Fair Value Measurements as of December 31, 2021
	Total		Level 1		Level 2		Level 3
Cash and cash equivalents	$	918	$	918	$	—	$	—

The Company had no transfers of assets or liabilities between fair value hierarchy levels between December 31, 2021 and March 31, 2022.

13. Related Parties

Management Services

The Company is assessed a quarterly fee to Indigo Partners, LLC (“Indigo Partners”) for management services, plus expense reimbursements and the annual fees of each member of the Company’s board of directors that is affiliated with Indigo Partners. Indigo Partners manages an investment fund that is the controlling stockholder of the Company. The expenses related to Indigo Partners’ management fees, expense reimbursements and director compensation were less than $1 million for the three months ended March 31, 2022 and 2021, which are included as other operating expenses within the Company’s condensed consolidated statements of operations.

Codeshare Arrangement

The Company entered into a codeshare agreement with Controladora Vuela Compañía de Aviación, S.A.B. de C.V. (an airline based in Mexico doing business as “Volaris”) during 2018, under which sales began in July 2018. Two of the Company’s directors are members of the board of directors of Volaris. As of March 31, 2022, Indigo Partners holds approximately 18% of the total outstanding common stock of Volaris.

In August 2018, the Company and Volaris began operating scheduled codeshare flights. The codeshare agreement provides for codeshare fees and revenue sharing for the codeshare flights. Each party bears its own costs and expenses of performance under the agreement, is required to indemnify the other party for certain claims and losses arising out of or related to the agreement and is responsible for complying with certain marketing and product display guidelines. The codeshare agreement also establishes a joint management committee, which includes representatives from both parties and generally oversees the management of the transactions and relationships contemplated by the agreement. The codeshare agreement is subject to automatic renewals and may be terminated by either party at any time upon the satisfaction of certain conditions.

14. The Proposed Merger with Spirit Airlines, Inc.

On February 5, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Top Gun Acquisition Corp. (“Merger Sub”), a direct wholly-owned subsidiary of the Company, and Spirit Airlines, Inc. (“Spirit”). The Merger Agreement provides that, among other things, the Merger Sub will be merged with and into Spirit (the “Merger”), with Spirit surviving the Merger and continuing as a wholly-owned subsidiary of the Company.

The closing of the Merger is subject to the satisfaction of customary conditions, including, but not limited to: (i) the adoption of the Merger Agreement by Spirit’s stockholders; (ii) the expiration or termination of all applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other required regulatory approvals including the receipt of all consents, registrations, notices, waivers, exemptions, approvals, confirmations, clearances, permits, certificates, orders, and authorizations of the U.S. Department of Justice, the Federal Trade Commission, Federal Aviation Administration, the DOT, and the Federal Communications Commission; (iii) the absence of any law or order prohibiting the consummation of the transactions; (iv) the effectiveness of a registration statement on Form S-4 filed by the Company registering shares of the Company’s common stock to be issued in the Merger; (v) the authorization and approval for listing on NASDAQ of the Company’s shares to be issued to holders of Spirit’s common stock in the Merger; (vi) the absence of any material adverse effect (as defined in the Merger Agreement) on either party; (vii) the accuracy of the parties’ respective representations and warranties in the Merger Agreement, subject to specified materiality qualifications; and (viii) compliance by the parties with their respective covenants in the Merger Agreement in all material respects.

Subsequent to the closing of the Merger and at the effective time of the Merger, each share of common stock of Spirit, par value $0.0001 per share, issued and outstanding (other than shares owned by the Company, Spirit, or their

FRONTIER GROUP HOLDINGS, INC.

respective subsidiaries immediately prior to the effective time) will be converted into the right to receive 1.9126 shares of common stock, par value $0.001 per share, of the Company and $2.13 per share in cash, without interest.

The Merger Agreement also specifies termination rights for both Spirit and the Company including, without limitation, a right for either party to terminate the Merger if it is not consummated on or before February 5, 2023, subject to certain extensions if needed to obtain regulatory approvals. If the Merger Agreement were to be terminated in specified circumstances, including the acceptance of a “Superior Proposal” as defined in the Merger Agreement, Spirit would be required to pay the Company a termination fee of $94 million.

The Company currently expects the Merger to occur in the second half of 2022, although there can be no assurance regarding timing of completion of regulatory processes. The Merger Agreement also includes a methodology by which certain expenses will be borne by each company. During the three months ended March 31, 2022, the Company recorded $11 million of expenses related to the planned Merger with Spirit within transaction and merger-related costs within the condensed consolidated statement of operations. These costs included $8 million related to transaction costs, which are made up of banking, legal, and accounting fees, amongst others, charged in connection with the merger, and $3 million of retention bonus expense. Costs that become payable upon completion of the Merger, which include certain banking fees and retention bonus costs, will be recognized upon consummation of the Merger. The Company has capitalized $1 million of costs incurred related to the anticipated equity issuance as a component of other current assets on the condensed consolidated balance sheet.

On March 29, 2022, Spirit received an unsolicited proposal from JetBlue Airways Corporation (“JetBlue”) to acquire all outstanding shares of Spirit’s common stock for $33.00 per share in cash provided that, among other things, Spirit terminates the Merger Agreement in accordance with its terms. Such a termination has not occurred as of the date of this report and, on May 2, 2022, Spirit announced that its board of directors had determined not to pursue the JetBlue proposal.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

General

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our audited consolidated financial statements and the related notes and other financial information included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, which was filed with the Securities and Exchange Commission (“SEC”) on February 23, 2022 (the “2021 Annual Report”).

Overview

Frontier Airlines is an ultra low-cost carrier whose business strategy is focused on Low Fares Done Right. We are headquartered in Denver, Colorado and offer flights throughout the United States and to select near international destinations in the Americas. Our unique strategy is underpinned by our low-cost structure and superior low-fare brand.

Impact of the COVID-19 Pandemic

Beginning in March 2020, the rapid spread of the coronavirus (“COVID-19”), along with government-mandated restrictions on travel, required stay-in-place orders, and other social distancing measures, resulted in the decline in demand for air travel which continued to have a material adverse effect on our business and results of operations for the three months ended March 31, 2022 and the corresponding prior year period. We have received significant financial assistance from the U.S. Department of the Treasury (“Treasury”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), the first Payroll Support Program (the “PSP”), the second Payroll Support Program (the “PSP2”) and the third Payroll Support Program (the “PSP3”, and together with the PSP and the PSP2, the “PSPs”). Please refer to “Notes to Condensed Consolidated Financial Statements — 2. Impact of COVID-19” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations — COVID-19 Relief Funding” in our 2021 Annual Report for additional detail on the CARES Act and the PSPs, and “Notes to Condensed Consolidated Financial Statements — 7. Debt” further information on the promissory notes entered into with the Treasury as a result of participation in the PSPs (collectively, the “PSP Promissory Notes”). The impact on our condensed consolidated financial statements for the three months ended March 31, 2022 and 2021 are as follows:

On September 28, 2020, we entered into a loan agreement with the Treasury for a term loan facility of up to $574 million pursuant to the secured loan program established under the CARES Act (the “Treasury Loan”). As of December 31, 2021, we borrowed $150 million under the Treasury Loan, for which the right to draw any further funds lapsed in May 2021. On February 2, 2022, we repaid the Treasury Loan which included the $150 million principal balance along with accrued interest and associated fees of $1 million. Additionally, we recognized a $7 million non-cash charge on the extinguishment of debt for the three months ended March 31, 2022 from the write-off of unamortized deferred financing costs associated with the Treasury Loan.

During the three months ended March 31, 2021, we entered into an agreement with the Treasury for installment funding under the PSP2 (the “PSP2 Agreement”), under which we received $161 million, comprised of a $143 million grant (the “PSP2 Grant”) for the continuation of payroll support through March 31, 2021 and an $18 million unsecured 10-year, low-interest loan (the “PSP2 Promissory Note”). During the three months ended March 31, 2021, $140 million of PSP2 proceeds were received and the remaining $21 million was received during the second quarter of 2021. We recognized $125 million of PSP2 Grant proceeds, net of deferred financing costs, during the three months ended March 31, 2021 within CARES Act credits in our condensed consolidated statements of operations and $3 million was deferred until the second quarter of 2021. We also received $12 million of the PSP2 Promissory Note as of March 31, 2021.

In connection with our participation in the PSPs and the Treasury Loan, we have been and will continue to be subject to certain restrictions and limitations, including, but not limited to:

•restrictions on repurchases of equity securities listed on a national securities exchange or payment of dividends until February 2, 2023;

•requirements to maintain certain levels of scheduled services through March 31, 2022 (including to destinations where there may currently be significantly reduced or no demand);

•a prohibition on involuntary terminations or furloughs of employees (except for health, disability, cause, or certain disciplinary reasons) through September 30, 2021;

•limits on certain executive compensation, including limiting pay increases and severance pay or other benefits upon terminations, until April 1, 2023;

•limitations on the use of the grant funds exclusively for the continuation of payment of employee wages, salaries and benefits; and

•additional reporting and recordkeeping requirements.

As part of the PSP Promissory Notes and the Treasury Loan, we issued to the Treasury warrants to purchase 3,117,940 shares of our common stock at a weighted average price of $6.95 per share. The initial fair value of these warrants upon issuance was treated as a loan discount, which reduced the carrying value of the related Treasury Loan and PSP Promissory Notes, and is amortized utilizing the effective interest method as interest expense in our condensed consolidated statements of operations over the term of each loan. These awards were originally classified as liability-based awards within other current liabilities on the condensed consolidated balance sheets, with periodic mark to market remeasurements being included in interest expense in the condensed consolidated statements of operations given we only had the option of settling in cash prior to being publicly traded. As a result of our initial public offering of our common stock (the “IPO”), we have the intent and ability to settle the warrants issued to the Treasury in shares and as a result, as of April 6, 2021, we reclassified the warrant liability to additional paid-in capital on the condensed consolidated balance sheet and are no longer required to mark to market the warrants. We recorded no mark to market adjustments during the three months ended March 31, 2022, and recorded $20 million during the three months ended March 31, 2021, to interest expense within the condensed consolidated statements of operations. The Treasury has not exercised any warrants as of March 31, 2022.

The CARES Act also provided for an employee retention credit (“CARES Employee Retention Credit”), which is a refundable tax credit against certain employment taxes that we qualified for beginning on April 1, 2020. In December 2020, the CARES Employee Retention Credit program was extended and enhanced through June 30, 2021. The American Rescue Plan Act, enacted on March 11, 2021, further extended the availability of the CARES Employee Retention Credit through December 31, 2021. After the first quarter of 2021, we did not qualify for any additional CARES Employee Retention Credits. During the three months ended March 31, 2021, we recognized $11 million related to the CARES Employee Retention Credit within CARES Act credits in our condensed consolidated statements of operations.

Proposed Merger with Spirit Airlines, Inc.

On February 5, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Spirit Airlines, Inc. (“Spirit”) and Top Gun Acquisition Corp. (“Merger Sub”), a direct wholly-owned subsidiary of ours, where Merger Sub will merge with and into Spirit (the “Merger”), with Spirit continuing as a wholly-owned subsidiary of ours. Pursuant to the Merger Agreement, upon the ultimate completion of the merger we will combine with Spirit to create America's most competitive ultra-low fare airline. The Merger is expected to close in the second half of 2022, subject to satisfaction of customary closing conditions, including completion of the regulatory review process and approval by Spirit stockholders. Our controlling stockholder has approved the transaction and related issuance of shares of our common stock upon signing of the Merger Agreement. Each share of common stock of Spirit will be converted into the right to receive 1.9126 shares of our common stock, and $2.13 per share in cash, without interest. During the three months ended March 31, 2022, we recorded $11 million of expenses related to the

planned Merger with Spirit within transaction and merger-related costs within the condensed consolidated statement of operations. These costs included $8 million related to transaction costs, which are made up of banking, legal, and accounting fees, amongst others, charged in connection with the merger, and $3 million of retention bonus expense. Costs that become payable upon completion of the Merger, which include certain banking fees and retention bonus costs, will be recognized upon consummation of the Merger. Please refer to “Notes to Condensed Consolidated Financial Statements — 14. The Proposed Merger with Spirit Airlines, Inc.” for additional detail.

Results of Operations

Three Months Ended March 31, 2022 Compared to Three Months Ended March 31, 2021

Total operating revenues for the three months ended March 31, 2022 totaled $605 million, an increase of 123% compared to the three months ended March 31, 2021, primarily due to a 62% increase in capacity, as measured by available seat miles (“ASMs”), as the demand for leisure travel continues to recover from the COVID-19 pandemic. Additionally, our operating revenues were favorably impacted by a 38% increase in total revenue per available seat mile (“RASM”) as compared to the corresponding period in 2021.

Total operating expenses during the three months ended March 31, 2022 totaled $758 million, including $11 million of transaction and merger-related costs, resulting in a cost per available seat mile (“CASM”) of 10.19¢, compared to 7.89¢ for the three months ended March 31, 2021. Fuel expense was 156% higher during the three months ended March 31, 2022, as compared to the corresponding prior year period, driven by a 59% increase in fuel rates and a 62% increase in fuel consumption associated with a 62% increase in our capacity. Our non-fuel expenses increased by 95% compared to the corresponding prior year period, driven primarily by the $136 million benefit from the recognition of grant funding received under the PSP2 Agreement and CARES Employee Retention Credits during the three months ended March 31, 2021, along with higher capacity and the resulting increase in operations during the three months ended March 31, 2022. CASM (excluding fuel) increased by 20%, from 6.07¢ for the three months ended March 31, 2021 to 7.30¢ for the three months ended March 31, 2022. This was driven primarily by CARES Act credits and higher gains on sale-leaseback transactions that reduced our operating expenses during the three months ended March 31, 2021, partially offset by the fixed nature of aircraft rent and aircraft and engine deferral paybacks for the three months ended March 31, 2021, as well as a decrease in salaries, wages and benefits per ASMs as capacity growth outpaced headcount growth. Adjusted CASM (excluding fuel), which excludes the impact of the CARES Act credits, transaction and merger-related costs and early lease termination costs for the remaining A319 aircraft returned in 2021, decreased from 8.96¢ for the three months ended March 31, 2021 to 7.15¢ for the three months ended March 31, 2022. See the reconciliation to corresponding GAAP measures provided below.

We generated a net loss of $121 million during the three months ended March 31, 2022 and a net loss of $91 million during the three months ended March 31, 2021, as a result of the significant reduction in demand beginning in March 2020 caused by the COVID-19 pandemic. Our results for the three months ended March 31, 2022 include $11 million of transaction and merger-related costs within operating expenses and $7 million in other non-operating expenses related to the write-off of unamortized deferred financing costs due to the paydown of the Treasury Loan. Our results for the three months ended March 31, 2021 include CARES Act credits and other charges that in total reduced our operating expenses by $132 million. which included $136 million related to funding recognized from the PSP2 Grant and the recognition of CARES Employee Retention Credits partly offset by $4 million in costs incurred with the early termination of our A319 leased aircraft, and $20 million in other non-operating expenses related to mark to market adjustments associated with the warrants issued pursuant to the Treasury Loan and PSP Promissory Notes. As a result of our IPO and the resulting reclassification of warrants from liability-based awards to equity based awards, as of April 6, 2021, we no longer mark to market the warrants. Considering these aforementioned non-GAAP adjustments and the related tax expense/(benefit) of $6 million and ($30 million) for the three months ended March 31, 2022 and 2021, respectively, our adjusted net loss was $109 million for the three months ended March 31, 2022, as compared to an adjusted net loss of $173 million for the comparable prior year period. See the reconciliation to corresponding GAAP measures provided below.

Total operating revenue increased $334 million, or 123%, during the three months ended March 31, 2022, as compared to the three months ended March 31, 2021, as we experienced increased demand for leisure travel. Revenue was favorably impacted by the 62% capacity growth, as measured by ASMs, due to an increase of 12% in average aircraft in service during the three months ended March 31, 2022, compared to the corresponding prior year period and an average daily aircraft utilization of 10.8 hours per day in the three months ended March 31, 2022, a 48% increase from the corresponding prior year period, alongside an increase in load factor. Additionally, our RASM was favorably impacted by total revenue per passenger due to a 37% increase in fare revenue per passenger and a 32% increase in ancillary revenue per passenger as well as a 4.3% increase in load factors during the three months ended March 31, 2022, compared to the corresponding prior year period.

(a)Cost per ASM figures may not recalculate due to rounding.

(b)Represents $8 million in transaction costs, including banking, legal and accounting fees, and $3 million in employee retention costs incurred in connection with the anticipated merger with Spirit Airlines.

(c)As a result of an early termination and buyout agreement executed in May 2021 with one of our lessors, we were able to accelerate the removal of the remaining four A319 aircraft from our fleet. These aircraft were originally scheduled to return in December 2021 and were instead returned during the second and third quarters of 2021. During the three months ended March 31, 2021, we incurred $4 million in aircraft rent costs relating to the acceleration and resulting changes to our lease return obligations.

(d)Represents the recognition of $125 million of net grant funding received from the Treasury for payroll support during the three months ended March 31, 2021 as part of the PSP2 Agreement under the CARES Act, along with $11 million of CARES Employee Retention Credits.

(e)Adjusted CASM (excluding fuel) is included as a supplemental disclosure because we believe that excluding aircraft fuel is useful to investors as it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence. The price of fuel, over which we have limited control, impacts the comparability of period-to-period financial performance, and excluding the price of fuel allows management an additional tool to understand and analyze our non-fuel costs and core operating performance, and increases comparability with other airlines that also provide a similar metric. Adjusted CASM (excluding fuel) is not determined in accordance with GAAP and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

(f)On February 2, 2022, we repaid the Treasury Loan which resulted in a one-time write-off of the remaining $7 million in unamortized deferred financing costs related to the Treasury Loan. This amount is a component of interest expense.

(g)Represents the mark to market adjustment to the value of the warrants issued as part of the funding provided under the CARES Act. This amount is a component of interest expense. As a result of our IPO and the resulting reclassification of warrants from liability-based awards to equity-based awards, as of April 6, 2021, we no longer mark to market the warrants.

(h)Adjusted CASM including net interest is included as a supplemental disclosure because we believe it is a useful metric to properly compare our cost management and performance to other peers that may have different capital structures and financing strategies, particularly as it relates to financing primary operating assets such as aircraft and engines. Additionally, we believe this metric is useful because it removes

certain items that may not be indicative of base operating performance or future results. Adjusted CASM including net interest is not determined in accordance with GAAP, may not be comparable across all carriers and should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP.

Aircraft Fuel. Aircraft fuel expense increased by $131 million, or 156%, during the three months ended March 31, 2022, as compared to the corresponding prior year period. The increase was primarily due to a 59% increase in fuel rates and the 62% increase in fuel gallons consumed due to the higher capacity.

Salaries, Wages and Benefits. Salaries, wages and benefits expense increased by $33 million, or 24%, during the three months ended March 31, 2022, as compared to the corresponding prior year period. The increase was primarily due to higher crew expenses driven by an escalation in credit hours as a result of more capacity and the expansion in salaried support staff costs and employee benefit expenses for the three months ended March 31, 2022, as compared to the corresponding prior year period.

Aircraft Rent. Aircraft rent expense decreased by $10 million, or (7)%, during the three months ended March 31, 2022, as compared to the corresponding prior year period, primarily due to the payback of lease deferrals from 2020 recognized in 2021, while no lease deferrals were paid for the three months ended March 31, 2022. The decrease related to lease deferrals was partially offset by the increase in our fleet period-over-period.

Station Operations. Station operations expense increased by $35 million, or 50%, during the three months ended March 31, 2022, as compared to the corresponding prior year period, due to a 58% increase in departures and a 67% increase in passengers as demand continues to recover from the COVID-19 pandemic. In addition, we experienced a favorable impact of $8 million during the three months ended March 31, 2021 related to deferral agreements on certain leases with our airport facilities that were negotiated to manage liquidity during the recovery of the COVID-19 pandemic, which had no impact in 2022. These increases were partially offset by the fixed nature of certain charges.

Sales and Marketing. Sales and marketing expense increased by $15 million, or 88%, during the three months ended March 31, 2022, as compared to the corresponding prior year period, primarily due to higher credit card processing fees resulting from the 123% increase in revenue, in addition to increased sales support and advertising expenses. The following table presents our distribution channel mix:


	Three Months Ended March 31,
Distribution Channel	2022		2021		Change
Our website, mobile app and other direct channels	71	%	72	%	(1)	pt
Third-party channels	29	%	28	%	1	pt

Maintenance Materials and Repairs. Maintenance materials and repair expense increased by $8 million, or 31% during the three months ended March 31, 2022, as compared to the corresponding prior year period, primarily due to higher flight hours with a corresponding 12% increase in aircraft in service and higher utilization per aircraft compared to the corresponding prior year period. These increases were offset by a decrease in volume and extent of planned maintenance checks during the three months ended March 31, 2022, as compared to the corresponding prior year period.

Depreciation and Amortization. Depreciation and amortization expense increased by $5 million, or 63%, during the three months ended March 31, 2022 as compared to the corresponding prior year period, primarily due to an increase in capitalized maintenance.

CARES Act Credits. CARES Act credits decreased by $136 million during the three months ended March 31, 2022, as compared to the corresponding prior year period. During the three months ended March 31, 2022, we did not recognize any CARES Act credits due to cessation of the program in 2021. During the three months ended March 31, 2021, we recognized $125 million of the payroll support grant received from the Treasury as part of the PSP2 Agreement under the CARES Act, and $11 million in CARES Employee Retention Credits.

Transaction and Merger-Related Costs. As a result of the anticipated merger with Spirit, we incurred $11 million in related costs during the three months ended March 31, 2022, including $8 million in transaction costs which relate mostly to banking, legal and accounting fees, and $3 million in employee retention costs.

Other Operating Expenses. Other operating expenses increased by $31 million, or 182%, during the three months ended March 31, 2022, as compared to the corresponding prior year period. The increase was driven primarily by increases in travel expenses relating to crew accommodations, an $8 million decrease in sale leaseback gains due to more aircraft deliveries in the three months ended March 31, 2021, as compared to the three months ended March 31, 2022, and higher general and administrative costs and other operating costs due to an increase in capacity as demand continues to recover from the COVID-19 pandemic.

Other Income (Expense). Other income (expense) decreased by $13 million, or (62)%, during the three months ended March 31, 2022, as compared to the corresponding prior year period. The decrease was primarily due to $20 million in interest expense related to the mark to market adjustments of warrants issued in conjunction with the PSP Promissory Notes and the Treasury Loan during the three months ended March 31, 2021. As a result of our IPO and the resulting reclassification of warrants from liability-based awards to equity based awards, as of April 6, 2021, we no longer mark to market the warrants. This decrease in expense during the three months ended March 31, 2022 was offset by a $7 million loss from the extinguishment of debt from the write-off of unamortized deferred financing costs associated with the Treasury Loan.

Income Taxes. Our effective tax rate for the three months ended March 31, 2022 was a benefit of 24.8%, compared to a benefit of 19.5% for the three months ended March 31, 2021. The effective tax rate for the three months ended March 31, 2022 is higher than the statutory rate primarily due to the non-deductibility of certain executive compensation costs and other employee benefits. The effective tax rate for the three months ended March 31, 2021 includes the impact of the non-deductible interest from the mark to market adjustments from the issued warrants as part of our participation in the PSP, PSP2 and Treasury Loan partly offset by excess tax benefits associated with our stock-based compensation arrangements.

__________________

(a)Adjusted net income (loss), EBITDA and Adjusted EBITDA are included as supplemental disclosures because we believe they are useful indicators of our operating performance. Derivations of net income and EBITDA are well-recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in our industry.

Adjusted net income (loss), EBITDA and Adjusted EBITDA have limitations as analytical tools. Some of the limitations applicable to these measures include: Adjusted net income (loss), EBITDA and Adjusted EBITDA do not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; Adjusted net income (loss), EBITDA and Adjusted EBITDA do not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments; EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital needs; EBITDA, and Adjusted EBITDA do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our indebtedness or possible cash requirements related to our warrants; although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect any cash requirements for such replacements; and other companies in our industry may calculate Adjusted net income (loss), EBITDA and Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Because of these limitations, Adjusted net income (loss), EBITDA and Adjusted EBITDA should not be considered in isolation from or as a substitute for performance measures calculated in accordance with GAAP. In addition, because derivations of Adjusted net income (loss), EBITDA and Adjusted EBITDA are not determined in accordance with GAAP, such measures are susceptible to varying calculations and not all companies calculate the measures in the same manner. As a result, derivations of Net income and EBITDA, including Adjusted net income (loss) and Adjusted EBITDA, as presented may not be directly comparable to similarly titled measures presented by other companies.

For the foregoing reasons, each of Adjusted net income (loss), EBITDA and Adjusted EBITDA has significant limitations which affect its use as an indicator of our profitability. Accordingly, you are cautioned not to place undue reliance on this information.

(b)EBITDAR and Adjusted EBITDAR are included as a supplemental disclosure because we believe them to be useful solely as valuation metrics for airlines as their calculations isolate the effects of financing in general, the accounting effects of capital spending and acquisitions (primarily aircraft, which may be acquired directly, directly subject to acquisition debt, by capital lease or by operating lease, each of which is presented differently for accounting purposes), and income taxes, which may vary significantly between periods and for different airlines for reasons unrelated to the underlying value of a particular airline. However, EBITDAR and Adjusted EBITDAR are not determined in accordance with GAAP, are susceptible to varying calculations and not all companies calculate the measures in the same manner. As a result, EBITDAR and Adjusted EBITDAR, as presented, may not be directly comparable to similarly titled measures presented by other companies. In addition, EBITDAR and Adjusted EBITDAR should not be viewed as a measure of overall performance since they exclude aircraft rent, which is a normal, recurring cash operating expense that is necessary to operate our business. Accordingly, you are cautioned not to place undue reliance on this information.

Liquidity, Capital Resources and Financial Position

Overview

As of March 31, 2022, we had $727 million of cash and cash equivalents. We had $352 million of total debt, net, of which $145 million is short-term debt. Our total debt, net is comprised of our $200 million pre-delivery payment facility (“PDP Financing Facility”), $66 million in PSP Promissory Notes, $18 million in secured indebtedness for our headquarters building, and a $71 million pre-purchased miles facility with Barclays, partly offset by $3 million in deferred debt acquisition costs and other discounts.

On February 2, 2022, we repaid the Treasury Loan, which included the $150 million principal balance along with accrued interest and associated fees of $1 million. As a result, we recognized a $7 million non-cash charge from the write-off of unamortized deferred financing costs associated with the Treasury Loan for the three months ended March 31, 2022. By repaying the amounts outstanding under the Treasury Loan, our co-brand credit card program and related brand assets that collateralized the Treasury Loan are now unencumbered.

On February 5, 2022, we entered into the Merger Agreement with Merger Sub and Spirit. The Merger Agreement provides that, among other things, the Merger Sub will be merged with and into Spirit, with Spirit surviving the Merger and continuing as a wholly-owned subsidiary of ours. Subsequent to the closing of the Merger and at the effective time of the Merger, each share of common stock of Spirit, par value $0.0001 per share, issued and outstanding (other than shares owned by us, Spirit, or their respective subsidiaries immediately prior to the effective time) will be converted into the right to receive 1.9126 shares of our common stock, par value $0.001 per share, and $2.13 per share in cash, without interest. Based on the number of outstanding shares as of the close of business on April 29, 2022, as disclosed in Spirit’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, filed with the SEC on May 4, 2022, our cash requirement will be approximately $231 million in the aggregate, payable at the closing of the Merger.

We continue to monitor our covenant compliance with various parties, including, but not limited to, our lenders and credit card processors. As of March 31, 2022, we are in compliance with all of our covenants, except we have obtained a waiver of relief for the covenant provisions through the second quarter of 2022 related to one of our credit card processors that represents less than 10% of total revenues, which may require future waivers or an amendment to existing covenants to reflect the downturn due to the COVID-19 pandemic.

The following table presents the major indicators of our financial condition and liquidity.

Use of Cash and Future Obligations

Our cash requirements, and ability to generate the cash flow, have been and continue to be, adversely impacted by the COVID-19 pandemic. However, we expect to meet our cash requirements for the next twelve months through use of our available cash and cash equivalents and cash flows from operating activities. We expect to meet our long-term cash requirements, which includes the potential merger with Spirit, with cash flows from operating and financing activities, including, but not limited to, potential future borrowings on our credit facility and/or potential issuance of debt or equity. Our primary uses of cash are for working capital, aircraft pre-delivery payments, debt repayments, capital expenditures and maintenance reserve deposits.

Our single largest capital commitment relates to the acquisition of aircraft. As of March 31, 2022, we operated all of our 112 aircraft under operating leases. PDPs relating to future deliveries under our agreement with Airbus are required at various times prior to each aircraft’s delivery date. As of March 31, 2022, we had $285 million of PDPs held by Airbus which have been partially financed by our PDP Financing Facility. As of March 31, 2022 our PDP Financing Facility had $200 million outstanding which was drawn to capacity. As of March 31, 2022, we had an

obligation to purchase 232 A320neo family aircraft to be delivered by 2029, five of which had committed operating leases for 2022 deliveries. We are evaluating financing options for the remaining aircraft.

Additionally, we are required by some of our aircraft leases to pay maintenance reserves to our respective aircraft lessors in advance of our performance of major maintenance activities; these payments act as collateral for the lessors to ensure aircraft are returned in the agreed-upon condition at the end of the lease period. Qualifying payments that are expected to be recovered from lessors are recorded as aircraft maintenance deposits on our condensed consolidated balance sheets. A portion of our cash is, therefore, unavailable until after we have completed the scheduled maintenance in accordance with the terms of the operating leases. During each of the three months ended March 31, 2022 and 2021, we made $4 million in maintenance deposit payments to our lessors. As of March 31, 2022, we had $114 million in recoverable aircraft maintenance deposits on our condensed consolidated balance sheets, of which $12 million was included in accounts receivable because the eligible maintenance had been performed.

The following table summarizes current and long-term material cash requirements as of March 31, 2022, which we expect to fund primarily with operating cash flows (in millions):

Cash, cash equivalents and restricted cash at beginning of period	918		378
Cash, cash equivalents and restricted cash at end of period	$	727	$	429

Operating Activities

During the three months ended March 31, 2022, net cash used in operating activities totaled $87 million, which was driven by a $121 million net loss and non-cash adjustments totaling $24 million, partly offset by inflows from changes in operating assets and liabilities of $58 million.

The $58 million of inflows from changes in operating assets and liabilities includes:

•$90 million in increases in our air traffic liability as a result of increased bookings;

•$6 million in increases in other liabilities driven by growth in the business, reflected primarily through increases in our passenger tax accounts of $15 million, aircraft maintenance of $14 million and accrued fuel of $10 million, partially offset by a $26 million payment to FAPAInvest, LLC for their phantom equity units; and

•$5 million in increases in accounts payable; partly offset by

•increases in other long-term assets of $17 million driven by increases in deferred taxes and prepaid maintenance; increases in supplies and other current assets of $13 million driven by growth in the business including increased fuel balances; increase in accounts receivable of $9 million driven by increases in bookings; and a $4 million increase in aircraft maintenance deposits.

Our net loss of $121 million was also adjusted by the following non-cash items to arrive at cash used in operating activities:

•$40 million in deferred tax benefits; and

•$7 million in gains recognized on sale-leaseback transactions; partially offset by

•$13 million in depreciation and amortization;

•$7 million in losses from the extinguishment of debt; and

•$3 million in stock-based compensation expense.

During the three months ended March 31, 2021, net cash provided by operating activities totaled $30 million, which was driven by cash inflows from changes in operating assets and liabilities of $127 million, partly offset by a $91 million net loss resulting from the significant impact of COVID-19 pandemic on our operations and $6 million in non-cash adjustments.

The $127 million of inflows from changes in operating assets and liabilities includes:

•$95 million in increases in our air traffic liability due to increased demand; and

•$71 million in increases in other liabilities as our operational related accruals increased during the first quarter of 2021 in line with demand, capacity and overall departure increases; partially offset by

•increases in accounts receivable primarily due to higher credit card receivables and increases in our supplies and other current asset balances.

Our net loss of $91 million was also adjusted by the following non-cash items to arrive at cash provided by operating activities:

•$22 million in deferred tax benefits; and

•$15 million in gains recognized on sale-leaseback transactions; partially offset by

•$20 million in unrealized losses on the mark to market adjustments for our warrant liability with the Treasury;

•$8 million in depreciation and amortization; and

•$3 million in stock-based compensation expense.

In response to the COVID-19 pandemic, beginning in 2020, we were granted payment deferrals on leases included in our right-of-use assets for certain aircraft and engines from lessors along with airport facilities and other vendors that are not included in our right-of-use assets. As these deferred payments are made, we will recognize the deferred payments in aircraft rent or station operations, as applicable, in the condensed consolidated statements of operations. There were no deferrals or payments, and therefore no impact to aircraft rent or station operations within the condensed consolidated statements of operations for the three months ended March 31, 2022. The deferrals for three months ended March 31, 2021 decreased operating cash flows and unfavorably impacted our results of operations by $11 million, including a $19 million unfavorable impact to aircraft rent and an $8 million favorable impact to station operations. As of March 31, 2022, we had paid back all of our aircraft rent deferrals, and had $11 million in station deferrals which will be recognized to station operations within the condensed consolidated statements of operations in future periods as the deferrals are repaid.

As of March 31, 2022, we did not have any other off-balance sheet arrangements, as defined in Regulation S-K, that have or are reasonably likely to have a current or future effect on our results of operations, financial condition or cash flows.

Investing Activities

During the three months ended March 31, 2022, net cash used in investing activities totaled $33 million, driven by:

•$25 million in net payments for pre-delivery deposits;

•$7 million in cash outflows for capital expenditures; and

•$1 million in cash outflows relating to other investing activities.

During the three months ended March 31, 2021, net cash provided by investing activities totaled $7 million, driven by:

•$12 million in net refunds from pre-delivery deposits; partially offset by

•$3 million in cash outflows for capital expenditures; and

•$2 million in cash outflows relating to other investing activities.

Financing Activities

During the three months ended March 31, 2022, net cash used in financing activities was $71 million, driven by:

•$165 million in cash outflows from principal repayments on long-term debt, which includes the paydown of the $150 million Treasury Loan and $15 million in PDP Financing Facility payments; and

•$3 million in cash outflows for payments related to minimum tax withholdings of share-based awards; partially offset by

•$97 million in cash proceeds from debt issuances, made up of a $56 million draw on our Barclays facility and $41 million in draws on our PDP Financing Facility.

During the three months ended March 31, 2021, net cash provided by financing activities was $14 million, driven by:

•$26 million in cash proceeds from debt issuances, made up of $14 million in draws on our PDP Financing Facility and $12 million in borrowings related to the PSP2 Promissory Note; and

•$13 million cash inflows from sale-leaseback transactions related to A320 family aircraft delivered during the three months ended March 31, 2021; partially offset by

•$22 million in cash outflows from principal repayments on long-term debt, which includes $22 million in PDP Financing Facility payments; and

•$3 million in cash outflows for payments related to minimum tax withholdings of share-based awards.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

We are subject to market risks in the ordinary course of our business. These risks include commodity price risk, specifically with respect to aircraft fuel, as well as interest and foreign exchange rate risk. The adverse effects of changes in these markets could pose a potential loss as discussed below. The sensitivity analysis provided does not consider the effects that such adverse changes may have on overall economic activity, nor does it consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.

Aircraft Fuel. Our results of operations can vary materially due to changes in the price and availability of aircraft fuel and are also impacted by the number of aircraft in use and the number of flights we operate. Aircraft fuel represented approximately 28% and 23% of total operating expenses for the three months ended March 31, 2022 and 2021, respectively. Unexpected changes in the pricing of aircraft fuel or a shortage or disruption in the supply could have a material adverse effect on our business, results of operations and financial condition. Based on our fuel consumption over the last 12 months, a hypothetical 10% increase in the average price per gallon of aircraft fuel would have increased aircraft fuel expense over the last 12 months by approximately $71 million.

Our strategy has been primarily to purchase out-of-the-money call options which are intended to provide protection against a large upward movement in fuel prices, while also allowing us to participate in any material fall in fuel prices. As of March 31, 2022 and December 31, 2021 we had no fuel derivative contracts outstanding; however historically we measure our fuel derivative instruments at fair value, which is determined using standard option valuation models that use observable market inputs including contractual terms, market prices, yield curves, fuel price curves and measures of volatility. Changes in the related commodity derivative instrument cash flows may change by more or less than the fair value based on further fluctuations in futures prices. Outstanding financial derivative instruments expose us to credit loss in the event of non-performance by the counterparties to the agreements.

Interest Rates. As of March 31, 2022 we are subject to market risk associated with changing interest rates, due to LIBOR-based interest rates on our PDP Financing Facility, floating rate building note and our affinity card advance purchase of mileage credits. During the three months ended March 31, 2022, a hypothetical increase of 100 basis points in average annual interest rates on our variable-rate debt would have increased the annual interest expense by $3 million.

With respect to the PDP Financing Facility, we are exposed to interest rate risk through aircraft lease contracts for the time period between agreement of terms and commencement of the lease, where portions of the rental payments are adjusted and become fixed based on the seven or nine year swap rate. As part of our risk management program, we historically have entered into contracts in order to limit the exposure to fluctuations in interest rates. We did not enter into any swaps during the three months ended March 31, 2022 and 2021. As of March 31, 2022, we have no interest rate hedges outstanding.

Foreign Exchange. We have de minimis foreign currency risks related to our station operating expenses denominated in currencies other than the U.S. dollar, primarily the Mexican peso and the Dominican Republic peso. Our revenue is U.S. dollar denominated.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, refers to the controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports

that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during the quarter ended March 31, 2022 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their desired objectives. Management does not expect, however, that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we have been and will continue to be subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained. We believe the ultimate outcome of such lawsuits, proceedings and reviews is not reasonably likely, individually or in the aggregate, to have a material adverse effect on our business, results of operations and financial condition.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Quarterly Report on Form 10-Q, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, before making an investment decision related to our common stock. The risks and uncertainties described below may not be the only ones we face, and many of such risks have been and will be exacerbated by the coronavirus (“COVID-19”) pandemic. If any of these risks should occur, our business, results of operations, financial condition or growth prospects could be adversely affected. In those cases, the trading price of our common stock could decline and you may lose all or part of your investment.

Risks Related to Our Industry

The COVID-19 pandemic and measures to reduce its spread have had, and are expected to continue to have, a material adverse impact on our business, results of operations and financial condition.

COVID-19 has spread to almost every country in the world, including the United States. The World Health Organization has declared COVID-19 a pandemic. The outbreak of COVID-19 and the implementation of measures to reduce its spread have adversely impacted our business and continue to adversely impact our business in a number of ways. Multiple governments in countries we serve, principally the United States, have responded to the virus with air travel restrictions, closures or recommendations against air travel and the implementation of mandatory quarantine periods after travel, and certain countries we serve have required airlines to limit or completely stop operations. In response to the COVID-19 pandemic, we have significantly reduced capacity from our original plan and will continue to evaluate the need for further flight schedule adjustments. Although we have seen significant recovery of demand through the quarter ended March 31, 2022, as compared to the corresponding prior year period, we are unable to predict the future spread and impact of COVID-19, including future variants of the virus such as the recent Omicron variant and its respective subvariants, or the efficacy and adherence rates of vaccines and other therapeutics and the resulting measures that may be introduced by governments or other parties and what impact those measures may have on the demand for air travel. We are closely monitoring the impact of the Omicron variant, and any new variants or subvariants, and expect any impact to be short term in nature given the availability of vaccines and the likely increase in vaccination rates in response to these variants.

In response to the impacts of the COVID-19 pandemic, beginning in March 2020, we have taken measures to address the significant cash outflows resulting from the sharp decline in demand and we continue to evaluate options should the lack of demand for air travel continue beyond the near term. During 2020 and 2021, and through March 31, 2022, we also reduced our flight schedule to match demand levels and implemented various other initiatives to reduce costs and manage liquidity including, but not limited to:

•reducing planned headcount increases;

•reducing employee-related costs, including:

◦salary reductions and/or deferrals for our officers and board members;

◦suspension of merit salary increases for 2020; and

◦voluntary paid and unpaid leave of absence programs for employees not covered under labor arrangements, as well as certain employees covered under such arrangements, including pilots and flight attendants, that range from one month to six months;

•deferring aircraft deliveries;

•reducing or suspending discretionary expenses;

•reaching agreements with major vendors, which are primarily related to many of our aircraft and engine leases as well as airports, for deferral of payments;

•delaying non-essential maintenance projects;

•reducing non-essential capital projects;

•securing current funding and future liquidity from the CARES Act, as well as other financing sources; and

•amending certain debt covenant metrics to align with current and expected demand.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. On April 30, 2020 we entered into a Payroll Support Program Agreement with the U.S. Department of the Treasury (the “Treasury”) to receive funding through the Payroll Support Program (the “PSP”) over the second and third quarters of 2020. On September 28, 2020, we entered into a Loan and Guarantee Agreement (the “Treasury Loan Agreement”) with the Treasury for a secured term loan facility (the “Treasury Loan”); on January 15, 2021, we entered into an agreement with the Treasury for additional funding under the Payroll Support Extension Agreement (the “PSP2 Agreement”); and on April 29, 2021, we entered into an agreement with the Treasury for additional funding under the Payroll Support Program 3 Agreement. The funding we received is subject to significant restrictions and limitations. See “—We have agreed to certain restrictions on our business by accepting financing under the CARES Act.”

Additionally, we also outsource certain critical business activities to third parties, and we depend on a limited number of suppliers for our aircraft and engines. As a result, we have increased our reliance on the successful implementation and execution of the business continuity planning of such third-party service providers in the current environment. If one or more of such third parties experience operational failures as a result of the impacts of the COVID-19 pandemic or due to sanctions imposed by the United States and foreign government bodies in response to the recent conflict between Russia and Ukraine, or claim that they cannot perform due to a force majeure event, it may have a material adverse impact on our business, results of operations and financial condition.

The extent of the impact of the COVID-19 pandemic on our business, results of operations and financial condition will depend on future developments, including the currently unknowable duration of the COVID-19 pandemic; the efficacy and adherence rates of COVID-19 vaccines; the impact of existing and future governmental regulations, travel advisories, testing regimes and restrictions that are imposed in response to the COVID-19 pandemic; additional reductions to our flight capacity, or a voluntary temporary cessation of all flights, that we implement in response to the COVID-19 pandemic; and the impact of the COVID-19 pandemic on consumer behavior, such as a reduction in the demand for air travel, especially in our destination cities. The potential economic impact brought on by the COVID-19 pandemic is difficult to assess or predict, and it has already caused, and is likely to result in further, significant disruptions of global economies and financial markets, which may reduce our ability to access capital on favorable terms or at all, and increase the cost of capital. In addition, a recession, depression or other sustained adverse economic event, including, but not limited to, an inflationary economic environment and the disruption, instability and volatility in global markets as a result of international conflicts, such as the recent conflict between Russia and Ukraine, would materially adversely impact our business and the value of our common stock. The COVID-19 pandemic makes it more challenging for management to estimate future performance of our business, particularly over the near to medium term. A further significant decline in demand for our flights could have a materially adverse impact on our business, results of operations and financial condition.

We are also dependent upon successful COVID-19 vaccines, including an efficient distribution, sufficient supply and significant uptake by the general public, in order to normalize economic conditions, the airline industry and our business operations and to realize our growth plans and business strategy. We cannot predict if or when we will be able to resume full normal operations. The failure of a vaccine, including to the extent it is not effective against the future variants of the virus, significant unplanned adverse reactions to the vaccine, politicization of the vaccine or general public distrust of the vaccine could have an adverse effect on our business, results of operations

and financial condition. Legally required vaccine mandates have been imposed and have resulted in multiple unresolved court challenges, some of which remain ongoing. We cannot predict what policies we may elect to or be required to implement in the future, or the effect thereof on our business, including whether the imposition of a mandatory vaccination requirement could cause us to lose, or experience difficulties hiring, qualified personnel.

In addition, an outbreak of another disease or similar public health threat, or fear of such an event, that affects travel demand, travel behavior or government mandated travel restrictions and regulations, could adversely impact our business, results of operations and financial condition.

The COVID-19 pandemic may also exacerbate other risks described in this “Risk Factors” section, including, but not limited to, our competitiveness, demand for our services, shifting consumer preferences and our substantial amount of outstanding indebtedness.

We have agreed to certain restrictions on our business by accepting financing under the CARES Act.

In connection with our participation in the PSP, PSP2, PSP3 and the Treasury Loan, we have been and will continue to be subject to certain restrictions and limitations, including, but not limited to:

•restrictions on repurchases of equity securities listed on a national securities exchange and on payment of dividends until February 2, 2023;

•requirements to maintain certain levels of scheduled services through March 31, 2022 (including to destinations where there may currently be significantly reduced or no demand);

•a prohibition on involuntary terminations or furloughs of employees (except for health, disability, cause, or certain disciplinary reasons) through September 30, 2021;

•a prohibition on reducing the salary, wages or benefits of our employees (other than our executive officers or independent contractors, or as otherwise permitted under the terms of the PSP, PSP2 and PSP3) through September 30, 2021;

•limits on certain executive compensation, including limiting pay increases and severance pay or other benefits upon termination, until April 1, 2023;

•limitations on the use of the grant funds exclusively for the continuation of payment of employee wages, salaries and benefits; and

•additional reporting and recordkeeping requirements.

These restrictions and requirements could materially adversely impact our business, results of operations and financial condition by, among other things, requiring us to change certain of our business practices and to maintain or increase cost levels to maintain scheduled service and employment with little or no offsetting revenue, affecting retention of key personnel and limiting our ability to effectively compete with others in our industry who may not be receiving funding and may not be subject to similar limitations.

We cannot predict whether the assistance from the Treasury will be adequate to continue to pay our employees for the duration of the COVID-19 pandemic or whether additional assistance will be required or available in the future. There can be no assurance that loans or other assistance will be available through the CARES Act or any other legislation, or whether we will be eligible to receive any additional assistance, if needed.

The airline industry is exceedingly competitive, and we compete against legacy network airlines, low-cost carriers and other ultra low-cost carriers; if we are not able to compete successfully in our markets, our business, results of operations and financial condition may be materially adversely affected.

We face significant competition with respect to routes, fares and services. Within the airline industry, we compete with legacy network carriers, low-cost carriers (“LCCs”) and ultra low-cost carriers (“ULCCs”). Competition on most of the routes we presently serve is significant, due to the large number of carriers in those markets. Furthermore, other airlines may begin service or increase existing service on routes where we currently

face little or no competition. In almost all instances, our competitors are larger than us and possess significantly greater financial and other resources than we do.

The airline industry is particularly susceptible to price discounting because, once a flight is scheduled, airlines incur only nominal additional costs to provide service to passengers occupying otherwise unsold seats. Increased fare or other price competition could adversely affect our operations. Airlines typically use discount fares and other promotions to stimulate traffic during normally slower travel periods to generate cash flow and to increase revenue per available seat mile. The prevalence of discount fares can be particularly acute when a competitor has excess capacity to sell. Given the high levels of excess capacity among U.S. airlines generally as a result of the COVID-19 pandemic, we expect to face significant discounted fare competition as the U.S. market continues to recover. Moreover, many other airlines have unbundled their services, at least in part, by charging separately for services such as baggage and advance seat selection which previously were offered as a component of base fares. This unbundling and other cost-reducing measures could enable competitor airlines to reduce fares on routes that we serve.

In addition, airlines increase or decrease capacity in markets based on perceived profitability. If our competitors increase overall industry capacity, or capacity dedicated to a particular domestic or foreign region, market or route that we serve, it could have a material adverse impact on our business. For instance, in 2017 there was widespread capacity growth across the United States, including in many of the markets in which we operate. In particular, during 2017, both Southwest Airlines and United Airlines increased their capacity in Denver. The domestic airline industry has often been the source of fare wars undertaken to grow market share or for other reasons, including, for example, actions by American Airlines in 2015 and United Airlines in 2017 to match fares offered in many of their markets by ULCCs, with resulting material adverse effects on the revenues of the airlines involved. The increased capacity across the United States in 2017 exacerbated the competitive pricing environment, particularly beginning in the second quarter of 2017, and this activity continued throughout 2018 and the first half of 2019. Given the decreased demand resulting from the COVID-19 pandemic, we expect significant competition, including price competition, at least in the short term and as the U.S. market continues to recover. If we continue to experience increased competition our business, results of operations and financial condition could be materially adversely affected.

We also expect that new work patterns and the growth of remote work will lead to increasing numbers of employees choosing to live remotely from their office location, which could significantly alter the historical demand levels on the routes we serve. While we believe our low fares and low costs will enable us to grow our network in new markets profitably to take advantage of new demand patterns as they arise, there can be no assurance that we will be successful in doing so or that we will be able to successfully compete with other U.S. airlines on such routes. If we fail to establish ourselves in such new markets our business, results of operations and financial condition could be materially adversely affected.

Our growth and the success of our ULCC business model could stimulate competition in our markets through our competitors’ development of their own ULCC strategies. Additionally, several new market entrants, including Avelo Airlines and Breeze Airways, have commenced, or announced their intent to commence, operations, which could present further competition should they develop ULCC strategies. For example, certain legacy network airlines have further segmented the cabins of their aircraft in order to enable them to offer a tier of reduced base fares designed to be competitive with those offered by us and other ULCCs. We expect the legacy airlines to continue to match LCC and ULCC pricing on portions of their network. A competitor adopting a ULCC strategy may have greater financial resources and access to lower cost sources of capital than we do, which could enable them to execute a ULCC strategy with a lower cost structure than we can. If these competitors adopt and successfully execute a ULCC business model, our business, results of operations and financial condition could be materially adversely affected.

There has been significant consolidation within the airline industry, including, for example, the combinations of American Airlines and US Airways, Delta Air Lines and Northwest Airlines, United Airlines and Continental Airlines, Southwest Airlines and AirTran Airways, Alaska Airlines and Virgin America, and our pending merger with Spirit Airlines, Inc. (“Spirit”). In the future, there may be additional consolidation in the airline industry.

Business combinations could significantly alter industry conditions and competition within the airline industry and could enable our competitors to reduce their fares.

The extremely competitive nature of the airline industry could prevent us from attaining the level of passenger traffic or maintaining the level of fares or revenues related to non-fare services required to achieve and sustain profitable operations in new and existing markets and could impede our growth strategy, which could harm our operating results. Due to our relatively small size, we are susceptible to a fare war or other competitive activities in one or more of the markets we serve, which could have a material adverse effect on our business, results of operations and financial condition.

Our business has been, and may in the future be, materially adversely affected by the price and availability of aircraft fuel. Unexpected pricing of aircraft fuel or a shortage or disruption in the supply of aircraft fuel could have a material adverse effect on our business, results of operations and financial condition.

The cost of aircraft fuel is highly volatile and in recent years has generally been one of our largest individual operating expenses, accounting for 28% and 23% of our operating expenses for the three months ended March 31, 2022 and 2021, respectively. High fuel prices or increases in fuel costs (or in the price of crude oil) would result in increased levels of expense, and we may not be able to increase ticket prices sufficiently to cover such increased fuel costs, particularly when fuel prices rise quickly, as occurred in 2021 and early 2022. We also sell a significant number of tickets to passengers well in advance of travel and, as a result, fares sold for future travel may not reflect such increased fuel costs. In addition, our ability to increase ticket prices to offset an increase in fuel costs is limited by the competitive nature of the airline industry and the price sensitivity associated with air travel, particularly leisure travel, and any increases in fares may reduce the general demand. Conversely, prolonged low fuel prices could limit our ability to differentiate our product and low fares from those of the legacy network airlines and LCCs, as prolonged low fuel prices could enable such carriers to, among other things, substantially decrease their costs, fly longer stages or utilize older aircraft. In addition, prolonged low fuel prices could also reduce the benefit we expect to receive from the new technology, more fuel-efficient A320neo family aircraft, we operate and have on order. See also “Risks Related to Our Business—We may be subject to competitive risks due to the long-term nature of our fleet order book and the unproven new engine technology utilized by the aircraft in our order book.” Aircraft fuel expense increased 156%, in the three months ended March 31, 2022 compared to the three months ended March 31, 2021, due to a 59% increase in price per gallon to $2.99 and a significant increase in fuel consumption due to higher utilization and more operating aircraft. Any future fluctuations in aircraft fuel prices or sustained high or low fuel prices could have a material adverse effect on our business, results of operations and financial condition.

Our business is also dependent on the availability of aircraft fuel (or crude oil), which is not predictable. Weather-related events, natural disasters, terrorism, wars, political disruption or instability involving oil-producing countries, changes in governmental or cartel policy concerning crude oil or aircraft fuel production, labor strikes, cyberattacks or other events affecting refinery production, transportation, taxes, marketing, environmental concerns, market manipulation, price speculation and other unpredictable events may drive actual or perceived fuel supply shortages. In particular, the recent conflict between Russia and Ukraine has caused shortages in the availability of aircraft fuel, including as a result of targeted sanctions and export control measures imposed by the United States and foreign government bodies. Although, for the three months ended March 31, 2022 any such shortages have not been material, there is no assurance that the shortages will not become more severe, and we cannot predict the continued impact of these sanctions and export control measures, or the impact of any further retaliatory actions that may be taken by Russia and the U.S. and foreign government bodies. Shortages in the availability of, or increases in demand for, crude oil in general, other crude oil-based fuel derivatives and aircraft fuel in particular have resulted, and could continue to result, in increased fuel prices and could have a material adverse effect on our business, results of operations and financial condition.

As of March 31, 2022, we had no fuel cash flow hedges for future fuel consumption, and fuel hedges therefore had no impact within our condensed consolidated statement of operations for the three months ended March 31, 2022. We cannot assure you our fuel hedging program will be effective or that we will maintain a fuel hedging program. Even if we are able to hedge portions of our future fuel requirements, we cannot guarantee that our hedge contracts will provide an adequate level of protection against increased fuel costs or that the counterparties to our

hedge contracts will be able to perform. Our fuel hedge contracts may contain margin funding requirements that could require us to post collateral to counterparties in the event of a significant drop in fuel prices in the future. Additionally, our ability to realize the benefit of declining fuel prices may be delayed by the impact of any fuel hedges in place, and we may record significant losses on fuel hedges during periods of declining prices. A failure of our fuel hedging strategy, significant margin funding requirements, overpaying for fuel through the use of hedging arrangements or our failure to maintain a fuel hedging program could prevent us from adequately mitigating the risk of fuel price increases and could have a material adverse effect on our business, results of operations and financial condition.

Restrictions on, or increased taxes applicable to, charges for non-fare products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations and financial condition.

For the three months ended March 31, 2022 and 2021, we generated non-fare passenger revenues of $359 million and $162 million, respectively. Our non-fare passenger revenue consists primarily of revenue generated from air travel-related services such as service fees, baggage fees, seat selection fees and other passenger-related revenue and is a component of passenger revenue within the condensed consolidated statements of operations. The U.S. Department of Transportation (“DOT”) has rules governing many facets of the airline-consumer relationship including, for instance, unfair or deceptive practices and unfair methods of competition including undisclosed display bias, lengthy tarmac delays, chronically delayed flights, consumer notice and disclosure requirements, consumer complaints, airline advertising and marketing practices, codeshare disclosure, oversales and involuntary denied boarding process and compensation, ticket refunds, liability for loss, delay or damage to baggage, customer service commitments, contracts of carriage, customer service commitments and the transportation of passengers with disabilities. The DOT periodically audits airlines to determine whether such airlines have violated any of the DOT rules. The DOT has conducted audits of our business and routine post-audit investigations of our business are ongoing. If the DOT determines that we are not, or have not been, in compliance with these rules or if we are unable to remain compliant, the DOT may subject us to fines or other enforcement action. For instance, in 2017 we were fined $0.4 million for certain infractions relating to oversales, rules related to passengers with disabilities and customer service plan rules; $40,000 for certain infractions relating to oversales disclosure and notice requirements, the domestic baggage liability limit rule and customer service plan rules; and $1.5 million relating to lengthy tarmac delays, which was offset by a $0.9 million credit for compensation provided to passengers on the affected flights and other delayed flights. In addition, on March 12, 2021, the DOT advised us that it was in receipt of information indicating that we had failed to comply with certain DOT consumer protection requirements relating to our consumer refund and credit practices and requested that we provide certain information to the DOT. The original DOT request for information and subsequent correspondence and requests have been focused on our refund practices on Frontier-initiated flight cancellations and/or significant schedule changes in flights as a result of the COVID-19 pandemic. We are fully cooperating with the DOT request and the review of this matter is still in process.

The DOT may also impose additional consumer protection requirements, including adding requirements to modify our websites and computer reservations system, which could have a material adverse effect on our business, results of operations and financial condition. The U.S. Federal Aviation Administration (“FAA”) Reauthorization Act of 2018 provided for several new requirements and rulemakings related to airlines including, but not limited to: (i) prohibition on voice communication cell phone use during certain flights, (ii) insecticide use disclosures, (iii) new training policy best practices for training regarding racial, ethnic and religious non-discrimination, (iv) training on human trafficking for certain staff, (v) departure gate stroller check-in, (vi) the protection of pets on airplanes and service animal standards, (vii) requirements to refund promptly to passengers any ancillary fees paid for services not received, (viii) consumer complaint process improvements, (ix) pregnant passenger assistance, (x) restrictions on the ability to deny a revenue passenger permission to board or involuntarily remove such passenger from the aircraft, (xi) minimum customer service standards for large ticket agents, (xii) information publishing requirements for widespread disruptions and passenger rights, (xiii) submission of plans pertaining to employee and contractor training consistent with the Airline Passengers with Disabilities Bill of Rights, (xiv) ensuring assistance for passengers with disabilities, (xv) flight attendant duty-period limitations and rest requirements, including submission of a fatigue risk management plan, (xvi) submission of policies concerning passenger sexual misconduct, (xvii)

development of an Employee Assault Prevention and Response Plan related to the customer service agents, (xviii) increased penalties available related to harm to passengers with disabilities or damage to wheelchairs or other mobility aids and (xix) minimum dimensions for passenger seats. Furthermore, in 2019, the FAA published an advance notice of proposed rulemaking regarding flight attendant duty-period limitations and rest requirements. The DOT also published a notice of proposed rulemaking in January 2020 regarding the accessibility features of lavatories and onboard wheelchair requirements on certain single-aisle aircraft with an FAA certificated maximum capacity of 125 seats or more, training flight attendants to proficiency on an annual basis to provide assistance in transporting qualified individuals with disabilities to and from the lavatory from the aircraft seat, and providing certain information on request to qualified individuals with a disability or persons inquiring on their behalf, on the carrier’s website and in printed or electronic form on the aircraft, concerning the accessibility of aircraft lavatories. In July 2021, the DOT issued a notice of proposed rulemaking requiring airlines to refund checked bag fees for delayed bags if they are not delivered to the passenger within a specified number of hours and refunding ancillary fees for services related to air travel that passengers did not receive. The DOT also recently published final rules regarding traveling by air with service animals, defining unfair or deceptive practices, clarifying that the maximum amount of denied boarding compensation that a carrier may provide to a passenger denied boarding involuntarily is not limited, prohibiting airlines from involuntarily denying boarding to a passenger after the passenger’s boarding pass has been collected or scanned and the passenger has boarded (subject to safety and security exceptions), raising the liability limits for denied boarding compensation, and raising the liability limit for mishandled baggage in domestic air transportation. The U.S. Congress and the DOT have examined the increasingly common airline industry practice of unbundling the pricing of certain products and ancillary services, a practice that is a core component of our business strategy. If new laws or regulations are adopted that make unbundling of airline products and services impermissible, or more cumbersome or expensive, or if new taxes are imposed on non-fare passenger revenues, our business, results of operations and financial condition could be harmed. Congressional, federal agency and other government scrutiny may also change industry practice or the public’s willingness to pay for non-fare ancillary services. See also “—We are subject to extensive regulation by the FAA, the DOT, TSA, U.S. Customs and Border Protection and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business, results of operations and financial condition.”

The demand for airline services is highly sensitive to changes in economic conditions, and another recession or similar economic downturn in the United States or globally would further weaken demand for our services and have a material adverse effect on our business, results of operations and financial condition, particularly since a substantial portion of our customers travel for leisure or other non-essential purposes.

The demand for travel services is affected by U.S. and global economic conditions. Unfavorable economic conditions, such as those resulting from an inflationary economic environment and/or reactions to the COVID-19 pandemic, have historically impaired airline economics. For most cost-conscious leisure travelers, travel is a discretionary expense, and though we believe ULCCs are best suited to attract travelers during periods of unfavorable economic conditions as a result of such carriers’ low base fares, travelers have often elected to replace air travel at such times with various other forms of ground transportation or have opted not to travel at all. Likewise, during periods of unfavorable economic conditions, businesses have deferred air travel or forgone it altogether. Travelers have also reduced spending by purchasing fewer non-fare services, which can result in a decrease in average revenue per passenger. Because airlines typically have relatively high fixed costs as a percentage of total costs, much of which cannot be mitigated during periods of lower demand for air travel, the airline business is particularly sensitive to changes in U.S. and global economic conditions. A reduction in the demand for air travel due to unfavorable economic conditions also limits our ability to raise fares to counteract increased fuel, labor and other costs. If U.S. or global economic conditions are unfavorable or uncertain for an extended period of time, including due to the disruption, instability and volatility in global markets resulting from the recent conflict between Russia and Ukraine, it could have a material adverse effect on our business, results of operations and financial condition. In particular, the ongoing COVID-19 pandemic and associated decline in economic activity and increase in unemployment levels have had, and may continue to have, a severe and prolonged effect on the global economy generally and, in turn, may continue to depress demand for air travel into the foreseeable future. Due to the

uncertainty surrounding the duration and severity of the COVID-19 pandemic, we can provide no assurance as to when and at what pace demand for air travel will return to pre-pandemic levels, if at all.

We face competition from air travel substitutes.

In addition to airline competition from legacy network airlines, LCCs and other ULCCs, we also face competition from air travel substitutes, partially as a result of the COVID-19 pandemic. On our domestic routes, particularly those with shorter stage lengths, we face competition from other transportation alternatives, such as buses, trains or automobiles. In addition, technology advancements may limit the demand for air travel. For example, video teleconferencing, virtual and augmented reality and other methods of electronic communication may reduce the need for in-person communication. Any inability to stimulate demand for air travel with our low base fares or to adjust rapidly in the event that the basis of competition in our markets changes could have a material adverse effect on our business, results of operations and financial condition.

Threatened or actual terrorist attacks or security concerns, particularly involving airlines, could have a material adverse effect on our business, results of operations and financial condition.

Past terrorist attacks or attempted attacks, particularly those against airlines, have caused substantial revenue losses and increased security costs, and any actual or threatened terrorist attack or security breach, even if not directly against an airline, could have a material adverse effect on our business, results of operations and financial condition. For instance, enhanced passenger screening, increased regulation governing carry-on baggage and other similar restrictions on passenger travel may further increase passenger inconvenience and reduce the demand for air travel. In addition, increased or enhanced security measures have tended to result in higher governmental fees imposed on airlines, resulting in higher operating costs for airlines, which we may not be able to pass on to consumers in the form of higher prices. Terrorist attacks made directly on an airline, particularly in the U.S., or the fear of such attacks or other hostilities, including elevated national threat warnings or selective cancellation or redirection of flights due to terror threats, would have a negative impact on the airline industry and could have a material adverse effect on our business, results of operations and financial condition.

Airlines are often affected by factors beyond their control, including: air traffic congestion at airports; air traffic control inefficiencies; government shutdowns; major construction or improvements at airports; aircraft and engine defects; FAA grounding of aircraft; adverse weather conditions; increased security measures; new travel-related taxes; or the outbreak of disease, any of which could have a material adverse effect on our business, results of operations and financial condition.

Like other airlines, our business is affected by factors beyond our control, including air traffic congestion at airports, air traffic control inefficiencies, government shutdowns, major construction or improvements at airports at which we operate, aircraft and engine defects, FAA grounding of aircraft, increased security measures, new travel-related identification requirements, taxes and fees, adverse weather conditions, natural disasters and the outbreak of disease. Flight delays caused by these factors may frustrate passengers and may increase costs and decrease revenues, which in turn could adversely affect profitability. The federal government controls all U.S. airspace, and airlines are completely dependent on the FAA to operate that airspace in a safe, efficient and affordable manner. The federal government also controls airport security. The air traffic control system, which is operated by the FAA, faces challenges in managing the growing demand for U.S. air travel. Federal government slowdowns or shutdowns may further impact the availability of federal resources, such as air traffic controllers and security personnel, necessary to provide air traffic control and airport security. Staffing shortages, such as those recently experienced at the Jacksonville Air Traffic Control Center during the first quarter of 2022 and which continue into the second quarter, can cause delays or cancellations of flights or may impact our ability to take delivery of aircraft or expand our route network or airport footprint. In addition, U.S. and foreign air-traffic controllers often rely on outdated technologies that routinely overwhelm the system and compel airlines to fly inefficient, indirect routes resulting in delays. Further, implementation of the Next Generation Air Transport System, or NextGen, by the FAA could result in changes to aircraft routings and flight paths that could lead to increased noise complaints and other lawsuits,

resulting in increased costs. The U.S. Congress could enact legislation that could impose a wide range of consumer protection requirements, which could increase our costs of doing business.

In addition, airlines may also experience disruptions to their operations as a result of the aircraft and engines they operate, such as manufacturing defects, spare part shortages and other factors beyond their control. For example, regulators ordered the grounding of the entire worldwide Boeing 737 MAX fleet in March 2019. While such order did not have a direct impact on our fleet, which is comprised entirely of Airbus A320 family aircraft, any similar or other disruption to our operations could have a material adverse effect on our business, results of operations and financial condition.

Adverse weather conditions and natural disasters, such as hurricanes, thunderstorms, blizzards, snowstorms or earthquakes, can cause flight cancellations or significant delays. Cancellations or delays due to adverse weather conditions or natural disasters, air traffic control problems or inefficiencies, breaches in security or other factors may affect us to a greater degree than other larger airlines that may be able to recover more quickly from these events, and therefore could have a material adverse effect on our business, results of operations and financial condition to a greater degree than other air carriers. Because of our high utilization and point-to-point network, operational disruptions can have a disproportionate impact on our ability to recover. In addition, many airlines re-accommodate their disrupted passengers on other airlines at prearranged rates under flight interruption manifest agreements. We have been unsuccessful in procuring any of these agreements with our peers, which makes our recovery from disruption more challenging than for larger airlines that have these agreements in place. Similarly, outbreaks of contagious diseases, such as COVID-19, Ebola, measles, avian flu, severe acute respiratory syndrome (SARS), H1N1 (swine) flu, pertussis (whooping cough) and Zika virus, have in the past and may in the future result in significant decreases in passenger traffic and the imposition of government restrictions in service, resulting in a material adverse impact on the airline industry. New identification requirements, such as the implementation of rules under the REAL ID Act of 2005, and increased travel taxes, such as those provided in the Travel Promotion Act, enacted in March 2010, which charges visitors from certain countries a $10 fee every two years to travel into the United States to subsidize certain travel promotion efforts, could also result in decreases in passenger traffic. Any general reduction in airline passenger traffic could have a material adverse effect on our business, results of operations and financial condition.

Risks associated with our presence in international emerging markets, including political or economic instability, and failure to adequately comply with existing legal requirements, may materially adversely affect our business, results of operations and financial condition.

Some of our target growth markets include countries with less developed economies, legal systems, financial markets and business and political environments that are vulnerable to economic and political disruptions, such as significant fluctuations in gross domestic product, interest and currency exchange rates, civil disturbances, government instability, nationalization and expropriation of private assets, trafficking and the imposition of taxes or other charges by governments. The occurrence of any of these events in markets served by us now or in the future and the resulting instability may have a material adverse effect on our business, results of operations and financial condition.

We emphasize compliance with all applicable laws and regulations and have implemented and continue to implement and refresh policies, procedures and certain ongoing training of our employees, third-party specialists and partners with regard to business ethics and key legal requirements; however, we cannot assure you that our employees, third-party specialists or partners will adhere to our code of ethics, other policies or other legal requirements. If we fail to enforce our policies and procedures properly or maintain adequate recordkeeping and internal accounting practices to record our transactions accurately, we may be subject to sanctions. In the event we believe, or have reason to believe, that our employees, third-party specialists or partners have or may have violated applicable laws or regulations, we may incur investigation costs, potential penalties and other related costs, which in turn may have a material adverse effect on our reputation, business, results of operations and financial condition.

Increases in insurance costs or reductions in insurance coverage may have a material adverse effect on our business, results of operations and financial condition.

If any of our aircraft were to be involved in a significant accident or if our property or operations were to be affected by a significant natural catastrophe or other event, we could be exposed to material liability or loss. If we are unable to obtain sufficient insurance (including aviation hull and liability insurance and property and business interruption coverage) to cover such liabilities or losses, whether due to insurance market conditions or otherwise, our business, results of operations and financial condition could be materially adversely affected.

We currently obtain third-party war risk (terrorism) insurance as part of our commercial aviation hull and liability policy and additional third-party war risk (terrorism) insurance through a separate policy with a different private insurance company. Our current third-party war risk (terrorism) insurance from commercial underwriters excludes nuclear, radiological and certain other events. If we are unable to obtain adequate war risk insurance or if an event not covered by the insurance we maintain were to take place, our business, results of operations and financial condition could be materially adversely affected.

A decline in, or temporary suspension of, the funding or operations of the U.S. federal government or its agencies may adversely affect our future operating results or negatively impact the timing and implementation of our growth prospects.

The success of our operations and our future growth is dependent on a number of federal agencies, specifically the FAA, the DOT and the U.S. Transportation Security Administration (“TSA”). In the event of a slowdown or shutdown of the federal government, such as those experienced in October 2013 and December 2018 through January 2019, certain functions of these and other federal agencies may be significantly diminished or completely suspended for an indefinite period of time, the conclusion of which is outside of our control. During such periods, it may not be possible for us to obtain the operational approvals and certifications required for events that are critical to the successful execution of our operational strategy, such as the delivery of new aircraft or the implementation of new routes. Additionally, there may be an impact on critical airport operations, particularly security, air traffic control and other functions that could cause airport delays and flight cancellations and negatively impact consumer demand for air travel.

Furthermore, once a period of slowdown or government shutdown has concluded, there will likely be an operational backlog within the federal agencies that may extend the length of time that such events continue to negatively impact our business, results of operations and financial condition beyond the end of such period.

The deployment of new 5G C-band service by wireless communications service providers could have a material adverse effect on our operations, which in turn could negatively impact our business, results of operations and financial condition.

On January 17, 2022, various executives of U.S. passenger airlines and cargo carriers, and airline industry associations, warned the U.S. federal government of the potential adverse impact the imminent deployment of AT&T and Verizon’s new 5G C-band service would have on U.S. aviation operations. According to aviation leaders, the deployment of the new 5G C-band service could cause, among other consequences, operational and security issues, interference with critical aircraft instruments and adverse impact to low-visibility operations. Any of these consequences could potentially cause flight cancellations, diversions and delays, or could result in damage to our aircraft and other equipment and a diminished margin of safety in airline operations. On January 18, 2022, AT&T and Verizon agreed to delay the implementation of 5G C-band service near airports while working with the FAA to develop long-term mitigations to support safe aviation operations. While AT&T and Verizon agreed to delay the activation of 5G transmitters in close proximity to airports, they did move forward with the activation of a vast majority of 5G transmitters away from airports, and we expect they will continue expanding their 5G C-band service through the spring of 2022. As a result, the FAA has taken precautionary steps to mitigate any remaining interference risks, which have resulted in minimal impacts to our operations, particularly in low-visibility conditions at certain airports. We cannot predict if any new requirements or restrictions will be imposed on airlines by the DOT, the FAA or other government agencies, but any such requirement or restriction could have an adverse effect

on our operations and any sustained impact to our operations could adversely affect our business, results of operations and financial condition.

Risks Related to the Merger

The pendency of the proposed Merger may cause disruption in our business.

On February 5, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Spirit and Top Gun Acquisition Corp., a direct wholly-owned subsidiary of ours (“Merger Sub”), pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit, with Spirit continuing as a wholly-owned subsidiary of ours.

The Merger Agreement restricts us from taking specified actions without Spirit’s consent until the Merger is completed or the Merger Agreement is terminated, including amending our organizational documents, issuing shares of our common stock, divesting certain assets (including certain intellectual property rights), declaring or paying dividends, making certain significant acquisitions or investments, entering into any new lines of business, or incurring certain indebtedness. These restrictions and others more fully described in the Merger Agreement (the full text of which has been filed with the SEC) may affect our ability to execute our business strategies and attain our financial and other goals and may impact our business, results of operations and financial condition.

The pendency of the proposed Merger could cause disruptions to our business or business relationships, which could have an adverse impact on our results of operations. Parties with which we have business relationships, including customers, unions, employees, suppliers, third-party service providers and third-party distribution channels, may be uncertain as to the future of such relationships and may delay or defer certain business decisions, seek alternative relationships with third parties or seek to alter their present business relationships with us. Parties with whom we otherwise may have sought to establish business relationships may seek alternative relationships with third parties.

The pursuit of the Merger and the preparation for our integration with Spirit’s business is expected to place a significant burden on our management and internal resources. The diversion of management’s attention away from day-to-day business concerns and any difficulties encountered in the transition and integration process could adversely affect our business, results of operations and financial condition.

While the Merger is pending, we intend to continue to grow our business which will entail the continued hiring of additional employees, including pilots and other skilled workers, presently in short supply in the airline industry. Any disruption or perceived uncertainty may make it more difficult for us to meet our employee retention and hiring goals which could materially impact our business, results of operations and financial condition.

We have incurred and will continue to incur significant costs, expenses and fees for professional services and other transaction costs in connection with the Merger. We may also incur unanticipated costs in connection with our integration with Spirit’s business. The substantial majority of these costs will be non-recurring expenses relating to the Merger, and many of these costs are payable regardless of whether or not the Merger is consummated. We also could be subject to litigation related to the proposed Merger, which could prevent or delay the consummation of the Merger and result in significant costs and expenses.

Failure to complete the Merger in a timely manner or at all could negatively impact the market price of our common stock, as well as our future business and our results of operations and financial condition.

The Merger cannot be completed until conditions to closing are satisfied or (if permissible under applicable law) waived. The Merger is subject to numerous closing conditions, including among other things, (i) approval of the transactions by Spirit’s stockholders, (ii) the expiration or termination of all applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other required regulatory approvals including the receipt of all consents, registrations, notices, waivers, exemptions, approvals, confirmations, clearances, permits, certificates, orders, and authorizations of the U.S. Department of Justice (“DOJ”), the Federal

Trade Commission, the FAA, the DOT, and the Federal Communications Commission (“FCC”); (iii) the absence of any law or order prohibiting the consummation of the transactions; (iv) the effectiveness of the registration statement to be filed by us and Spirit with the SEC pursuant to the Merger Agreement; (v) the authorization and approval for listing on Nasdaq of the shares of our common stock to be issued to holders of Spirit’s common stock in the Merger; (vi) the absence of any material adverse effect (as defined in the Merger Agreement) on either party; (vii) the accuracy of the parties’ respective representations and warranties in the Merger Agreement, subject to specified materiality qualifications; and (viii) compliance by the parties with their respective covenants in the Merger Agreement in all material respects.

The process of satisfying such conditions, including seeking the necessary regulatory approvals, could delay the completion of the Merger for a significant period of time or prevent it from occurring. Further, there can be no assurance that the conditions to the closing of the Merger will be satisfied or waived or that the Merger will be completed.

If the Merger is not completed in a timely manner or at all, our ongoing business may be adversely affected as follows:

•we may experience negative reactions from the financial markets, and our stock price could decline to the extent that the current market price reflects an assumption that the Merger will be completed;

•we may experience negative reactions from employees, customers, suppliers or other third parties;

•we may be subject to litigation, which could result in significant costs and expenses;

•management’s focus may have been diverted from day-to-day business operations and pursuing other opportunities that could have been beneficial to us; and

•our costs of pursuing the Merger may be higher than anticipated.

The Merger will also not be completed should Spirit terminate the Merger Agreement in accordance with its terms to accept the JetBlue proposal. Such a termination has not occurred as of the date of this report and, on May 2, 2022, Spirit announced that its board of directors had determined not to pursue the JetBlue proposal.

If the Merger is not consummated, there can be no assurance that these risks will not materialize and will not materially adversely affect our stock price, business, results of operations and financial condition.

In order to complete the Merger, we and Spirit must obtain certain governmental approvals, and if such approvals are not granted or are granted with conditions, completion of the Merger may be jeopardized or the anticipated benefits of the Merger could be reduced.

Although we and Spirit have agreed to use reasonable best efforts to make certain governmental filings and obtain the required governmental approvals, including from the FCC, the FAA, the DOJ and the DOT, subject to certain limitations such as the expiration or earlier termination of relevant waiting periods under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, there can be no assurance that the relevant waiting periods will expire or be terminated or that the relevant approvals will be obtained. As a condition to approving the Merger, these governmental authorities may impose conditions, terms, obligations or restrictions or require divestitures or place restrictions on the conduct of our business after completion of the Merger. There can be no assurance that regulators will not impose conditions, terms, obligations or restrictions and that such conditions, terms, obligations or restrictions will not have the effect of delaying or preventing completion of the Merger or imposing additional material costs on or materially limiting the revenues of the combined company following the Merger, or otherwise adversely affecting, including to a material extent, our business, results of operations and financial condition after completion of the Merger. If we are required to divest assets or businesses, there can be no assurance that we will be able to negotiate such divestitures expeditiously or on favorable terms or that the governmental authorities will

approve the terms of such divestitures. We can provide no assurance that these conditions, terms, obligations or restrictions will not result in the abandonment of the Merger.

Although we expect that the Merger will result in synergies and other benefits to us, we may not realize those benefits because of difficulties related to integration, the achievement of such synergies and other challenges.

We and Spirit have operated and, until completion of the Merger, will continue to operate, independently, and there can be no assurances that our businesses can be combined in a manner that allows for the achievement of substantial benefits. Historically, the integration of separate airlines has often proven to be more time consuming, to cost more and to require more resources than initially estimated. We must devote significant management attention and financial and other resources to integrating our business practices, cultures and operations. If we are not able to successfully integrate our business with Spirit’s, the anticipated benefits, including synergies, of the Merger may not be realized fully or may take longer than expected to be realized. Specifically, the following issues, among others, must be addressed in combining our operations with Spirit’s in order to realize the anticipated benefits of the Merger:

•combining our business with Spirit’s in a manner that permits us to achieve the synergies anticipated to result from the Merger, the failure of which would result in the anticipated benefits of the Merger not being realized in the time frame currently anticipated or at all;

•maintaining existing agreements with unions, employees, suppliers, third-party service providers and third-party distribution channels, and avoiding delays in entering into new agreements with prospective employees, suppliers, third-party service providers and third-party distribution channels;

•the challenge of integrating complex systems and technologies, including designing and implementing an integrated customer reservations system, operating procedures, regulatory compliance programs, aircraft fleets, networks, and other assets in a manner that minimizes any adverse impact on customers, suppliers, employees and other constituencies;

•determining whether and how to address possible differences in corporate cultures and management philosophies;

•diversion of the attention of management and other key employees;

•integrating the businesses’ administrative and information technology infrastructure;

•the challenge of integrating workforces and attracting and retaining key personnel while maintaining focus on providing consistent, high quality customer service and running an efficient operation;

•managing the expanded operations of a significantly larger and more complex company;

•branding or rebranding initiatives may involve substantial costs and may not be favorably received by customers; and

•resolving potential unknown liabilities, adverse consequences and unforeseen increased expenses associated with the Merger.

Even if the operations of our business and Spirit’s business are integrated successfully, the full benefits of the Merger may not be realized, including, among others, the synergies that are expected. These benefits may not be achieved within the anticipated time frame or at all. Additional unanticipated costs, which could be material, may also be incurred in the integration of our business and Spirit’s business. Further, it is possible that there could be loss of key Frontier or Spirit employees, loss of customers, disruption of either or both of our or Spirit’s ongoing businesses or unexpected issues, higher than expected costs and an overall post-completion process that takes longer than originally anticipated.

We plan to submit to the FAA a transition plan for merging the day-to-day operations of Frontier and Spirit under a single operating certificate. The issuance of a single operating certificate will occur when the FAA agrees that we have achieved a level of integration that can be safely managed under one certificate. The actual time required and cost incurred to receive this approval cannot be predicted. Any delay in the grant of such approval or increase in costs beyond those presently expected could have a material adverse effect on the completion date of our integration plan and receipt of the benefits expected from that plan. See also “—We face challenges in integrating our computer, communications and other technology systems.” All of these factors could materially adversely affect our business, results of operations and financial condition.

We may face challenges in integrating our computer, communications and other technology systems.

Among the principal risks of integrating our and Spirit’s businesses and operations are the risks relating to integrating various computer, communications and other technology systems, including designing and implementing an integrated customer reservations system, that will be necessary to operate Frontier and Spirit as a single airline and to achieve cost synergies by eliminating redundancies in the businesses. The integration of these systems in a number of prior airline mergers has taken longer, been more disruptive and cost more than originally forecasted. The implementation process to integrate these various systems will involve a number of risks that could adversely impact our business, results of operations and financial condition. The related implementation will be a complex and time-consuming project involving substantial expenditures for implementation consultants, system hardware, software and implementation activities, as well as the transformation of business and financial processes.

As with any large project, there will be many factors that may materially affect the schedule, cost and execution of the integration of our computer, communications and other technology systems. These factors include, among others: problems during the design, implementation and testing phases; systems delays and/or malfunctions; the risk that suppliers and contractors will not perform as required under their contracts; the diversion of management attention from daily operations to the project; reworks due to unanticipated changes in business processes; challenges in simultaneously activating new systems throughout our global network; difficulty in training employees in the operations of new systems; the risk of security breach or disruption; and other unexpected events beyond our control. We cannot assure you that our security measures, change control procedures or disaster recovery plans will be adequate to prevent disruptions or delays. Disruptions in or changes to these systems could result in a disruption to our business and our operations and the loss of important data. Any of the foregoing could result in a material adverse effect on our business, results of operations and financial condition.

The combined company is expected to incur substantial expenses related to the Merger and the integration of Frontier and Spirit.

The combined company is expected to incur substantial expenses in connection with the Merger and the integration of Frontier and Spirit. There are a large number of processes, policies, procedures, operations, technologies and systems that must be integrated, including purchasing, accounting and finance, sales, payroll, pricing, revenue management, reservations, maintenance, flight operations, marketing and benefits. While we and Spirit have assumed that a certain level of expenses would be incurred, there are many factors beyond their control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that the combined company expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will result in the combined company taking significant charges against earnings following the completion of the Merger, and the amount and timing of such charges are uncertain at present.

Uncertainties associated with the Merger may cause a loss of management personnel and other key employees which could adversely affect the future business and operations of the combined company.

We and Spirit are dependent on the experience and industry knowledge of our respective officers and other key employees to execute our respective business plans. The combined company’s success after the Merger will depend in part upon the ability of our and Spirit’s to retain key management personnel and other key employees. Current and prospective employees of Frontier and Spirit may experience uncertainty about their roles within the combined company following the Merger, which may have an adverse effect on the ability of each of us and Spirit to attract or retain key management and other key personnel. Accordingly, no assurance can be given that the combined

company will be able to attract or retain key management personnel and other key employees of Frontier and Spirit to the same extent that Frontier and Spirit have previously been able to attract or retain their own employees.

The future results of the combined company will suffer if the combined company does not effectively manage its expanded operations following the Merger.

Following the Merger, the size of the business of the combined company will increase significantly beyond the current size of either our or Spirit’s business. The combined company’s future success depends, in part, upon its ability to manage this expanded business, which will pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the Merger.

Following the closing of the Merger, we will be bound by all of the obligations and liabilities of both companies.

Following the closing, we will become bound by all of the obligations and liabilities of the Company and Spirit. Neither we nor Spirit can predict the financial condition of the Company or Spirit at the time of that combination or our ability to satisfy the obligations and liabilities of the combined company.

The need to integrate the Frontier and Spirit workforces following the Merger and negotiate new joint labor agreements presents the potential for delay in achieving expected synergies, increased labor costs or labor disputes that could adversely affect the combined company’s operations.

The successful integration of us and Spirit and achievement of the anticipated benefits of the combination depend significantly on integrating our and Spirit’s employee groups and on maintaining productive employee relations. Failure to do so presents the potential for delays in achieving expected synergies of integration, increased labor costs and labor disputes that could adversely affect the combined company’s operations.

We and Spirit are both highly unionized companies. The process for integrating labor groups in an airline merger is governed by a combination of the United States Railway Labor Act (“RLA”), the McCaskill-Bond Act, and where applicable, the existing provisions of each company’s collective bargaining agreements and union policy. Pending operational integration, it is generally necessary to maintain a “fence” between employee groups, during which time the combined company will keep the employee groups separate and apply the terms of the existing collective bargaining agreements unless other terms have been negotiated.

Under the RLA, the National Mediation Board (“NMB”) has exclusive authority to resolve representation disputes arising out of airline mergers. The disputes that the NMB has authority to resolve include (i) whether the merger has created a “single carrier” for representation purposes; (ii) designation of the appropriate “craft or class”—the RLA term for “bargaining unit”—for bargaining at the combined company on a system wide basis, an issue which typically arises from minor inconsistencies over which positions are included within a particular craft or class at the two companies; and (iii) designation of the representative of each craft or class at the combined company.

In order to fully integrate the pre-merger represented employee groups, the combined company must negotiate a joint collective bargaining agreement covering each combined group. These negotiations can begin immediately where the same union represents employees of both companies within the craft or class in question, but otherwise will likely begin after a single post-merger representative has been certified by the NMB.

Prior to the completion of the Merger, there is a risk of litigation or arbitration by unions or individual employees that could delay or halt the Merger or result in monetary damages on the basis that the Merger either violates a provision of an existing collective bargaining agreement or an obligation under the RLA or other applicable law. The unions or individual employees might also pursue judicial or arbitral claims arising out of changes implemented as a result of the Merger. There is also a possibility that employees or unions could engage in

job actions such as slow-downs, work-to-rule campaigns, sick-outs or other actions designed to disrupt our and Spirit’s normal operations, whether in opposition to the Merger or in an attempt to pressure the companies in collective bargaining negotiations. Although the RLA makes such actions unlawful until the parties have been lawfully released to self-help, and we and Spirit can seek injunctive relief against premature self-help, such actions can cause significant harm even if ultimately enjoined.

Risks Related to Our Business

If we fail to implement our business strategy successfully, our business, results of operations and financial condition could be materially adversely affected.

Our growth strategy includes significantly expanding our fleet and expanding the number of markets we serve. We select target markets and routes where we believe we can achieve profitability within a reasonable timeframe, and we only continue operating on routes where we believe we can achieve and maintain our desired level of profitability. When developing our route network, we focus on gaining market share on routes that have been underserved or that are served primarily by higher cost airlines, where we believe we have a competitive cost advantage. Effectively implementing our growth strategy is critical for our business to achieve economies of scale and to sustain or increase our profitability. We face numerous challenges in implementing our growth strategy, including our ability to:

•sustain our relatively low unit operating costs;

•continue to realize attractive revenue performance;

•achieve and maintain profitability;

•maintain a high level of aircraft utilization; and

•access airports located in our targeted geographic markets where we can operate routes in a manner that is consistent with our cost strategy.

In addition, in order to successfully implement our growth strategy, which includes the planned growth of our fleet size and a firm commitment to purchase 232 A320neo family aircraft by the end of 2029, we will require access to a large number of gates and other services at airports we currently serve or may seek to serve. We believe there are currently significant restraints on gates and related ground facilities at many of the most heavily utilized airports in the United States, in addition to the fact that three major domestic airports (JFK and LaGuardia in New York and Reagan National in Washington, D.C.) require government-controlled take-off or landing “slots” to operate at those airports. As a result, if we are unable to obtain access to a sufficient number of slots, gates or related ground facilities at desirable airports to accommodate our growing fleet, we may be unable to compete in those markets, our aircraft utilization rate could decrease and we could suffer a material adverse effect on our business, results of operations and financial condition.

Our growth is also dependent upon our ability to maintain a safe and secure operation, including enhanced safety procedures as a result of the COVID-19 pandemic, and will require additional personnel, equipment and facilities as we continue to induct new aircraft and execute our growth plan. In addition, we will require additional third-party personnel for services we do not undertake ourselves. An inability to hire and retain personnel, secure the required equipment and facilities in a cost-effective and timely manner, efficiently operate our expanded facilities or obtain the necessary regulatory approvals may adversely affect our ability to achieve our growth strategy, which could harm our business. Furthermore, expansion to new markets may have other risks due to factors specific to those markets. We may be unable to foresee all of the existing risks upon entering certain new markets or respond adequately to these risks, and our growth strategy and our business may suffer as a result. In addition, our competitors may reduce their fares and/or offer special promotions following our entry into a new market. We cannot assure you that we will be able to profitably expand our existing markets or establish new markets.

Some of our target growth markets outside of the United States include countries with less developed economies that may be vulnerable to unstable economic and political conditions, such as significant fluctuations in gross domestic product, interest and currency exchange rates, civil disturbances, government instability, nationalization and expropriation of private assets and the imposition of taxes or other charges by governments. The

occurrence of any of these events in markets we serve, and the resulting instability, may adversely affect our ability to implement our growth strategy.

Our low-cost structure is one of our primary competitive advantages, and many factors could affect our ability to control our costs.

Our low-cost structure is one of our primary competitive advantages. However, we have limited control over some of our costs. For example, we have limited control over the price and availability of aircraft fuel, aviation insurance, the acquisition and operating cost of aircraft, airport and related infrastructure costs, taxes, the cost of meeting changing regulatory requirements and our cost to access capital or financing. In addition, the compensation and benefit costs applicable to a significant portion of our employees are established by the terms of collective bargaining agreements, which could result in increased labor costs. See “— Increased labor costs, union disputes, employee strikes and other labor-related disruption may adversely affect our business, results of operations and financial condition.” Further, in an inflationary environment which is also exhibiting worker and fuel shortages, such as the current U.S. economic environment, depending on airline industry and other economic conditions, we may be unable to manage through the resulting increases in our operating costs. We cannot predict how long the current inflationary period will last or the extent to which high inflation may occur in the U.S. economy in the future. As such, we cannot guarantee we will be able to maintain our relatively low costs. If our costs increase and we are no longer able to maintain a competitive cost structure, it could have a material adverse effect on our business, results of operations and financial condition.

We may not be able to grow or maintain our unit revenues or maintain our non-fare revenues.

A key component of our Low Fares Done Right strategy is attracting customers with low fares and garnering repeat business by delivering a high-quality, family-friendly customer experience with a more upscale look and feel than traditionally experienced on other ULCCs in the United States. We intend to continue to differentiate our brand and product in order to expand our loyal customer base and grow or maintain our unit revenues and maintain our non-fare revenues. The rising cost of aircraft and engine maintenance may impair our ability to offer low-cost fares, resulting in reduced revenues. Differentiating our brand and product has required, and will continue to require, significant investment, and we cannot assure you that the initiatives we have implemented will continue to be successful or that the initiatives we intend to implement will be successful. If we are unable to maintain or further differentiate our brand and product from the other U.S. ULCCs, our market share could decline, which could have a material adverse effect on our business, results of operations and financial condition. We may also not be successful in leveraging our brand and product to stimulate new demand with low base fares or gain market share from the legacy airlines, particularly if the significant excess capacity caused by the COVID-19 pandemic persists.

In addition, our business strategy includes maintaining our portfolio of desirable, value-oriented, non-fare products and services. However, we cannot assure you that passengers will continue to perceive value in the non-fare products and services we currently offer and regulatory initiatives could adversely affect non-fare revenue opportunities. Failure to maintain our non-fare revenues could have a material adverse effect on our business, results of operations and financial condition. Furthermore, if we are unable to maintain our non-fare revenues, we may not be able to execute our strategy to continue to lower base fares in order to stimulate demand for air travel.

Increased labor costs, union disputes, employee strikes and other labor-related disruption may adversely affect our business, results of operations and financial condition.

Our business is labor intensive, with labor costs representing approximately 23% and 38% of our total operating costs for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, approximately 88% of our workforce was represented by labor unions. We have ratified labor agreements with several of the labor unions representing our employees, including with the union representing our pilots in January 2019 and with the union representing our flight attendants in May 2019. See “Business—Human Capital Resources” in our 2021 Annual Report. We cannot assure you that our labor costs going forward will remain competitive or that any new agreements into which we enter will not have terms with higher labor costs or that the negotiations of such labor agreements will not result in any work stoppages.

Relations between air carriers and labor unions in the United States are governed by the RLA. Under the RLA, collective bargaining agreements generally contain “amendable dates” rather than expiration dates, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage, and usually lengthy, series of bargaining processes overseen by the NMB. This process continues until either the parties have reached agreement on a new collective bargaining agreement, or the parties have been released to “self-help” by the NMB. In most circumstances, the RLA prohibits strikes; however, after release by the NMB, carriers and unions are free to engage in self-help measures such as lockouts and strikes.

From June to November 2018, we experienced disruptions to our flight operations during our labor negotiations with the union representing our pilots, Air Line Pilots Association (“ALPA”), which materially impacted our business and results of operations for the period. Upon reaching a tentative agreement with ALPA in December 2018, our flight operations returned to normal. However, we are unable to determine the extent to which this period of prolonged disruption may have harmed our reputation or the length of time it may take for our business to recover from such harm, if ever. In addition, the agreement, which became effective in January 2019, included a significant increase in the annual compensation of our pilots, as well as a one-time ratification incentive payment to our pilots of $75 million, plus payroll-related taxes. We cannot provide assurance that we will not experience another operational disruption resulting from any future negotiations or disagreements with our pilots or with any of our other union-represented employee groups. In addition, we cannot provide any estimate with regard to the amount or probability of future compensation increases, ratification incentives or other costs that may come as a result of future negotiations with our pilots or our other union-represented groups. Future operational disruptions or other costs related to labor negotiations, including reputational harm that may come as a result of such disruptions, if any, may have a material adverse impact on our business, results of operations and financial condition.

In addition, the terms and conditions of our future collective bargaining agreements may be affected by the results of collective bargaining negotiations at other airlines that may have a greater ability, due to larger scale, greater efficiency, superior profitability or other factors, to bear higher costs than we can. One or more of our competitors may also significantly reduce their labor costs, thereby providing them with a competitive advantage over us. Our labor costs may also increase in connection with our growth and we could also become subject to additional collective bargaining agreements in the future as non-unionized workers may unionize. The occurrence of any such event may have a material adverse impact on our business, results of operations and financial condition.

Our inability to expand or operate reliably or efficiently out of airports where we maintain a large presence could have a material adverse effect on our business, results of operations and financial condition.

We are highly dependent on markets served from airports that are significant to our business, including Orlando, Denver, Las Vegas, Philadelphia and Tampa. Our results of operations may be affected by actions taken by governmental or other agencies or authorities having jurisdiction over our operations at these and other airports, including, but not limited to:

•increases in airport rates and charges;

•limitations on take-off and landing slots, airport gate capacity or other use of airport facilities;

•termination of our airport use agreements, some of which can be terminated by airport authorities with little notice to us;

•increases in airport capacity that could facilitate increased competition;

•international travel regulations such as customs and immigration;

•increases in taxes;

•changes in the law that affect the services that can be offered by airlines, in general and in particular markets or at particular airports;

•restrictions on competitive practices;

•the adoption of statutes or regulations that impact or impose additional customer service standards and requirements, including security standards and requirements; and

•the adoption of more restrictive locally imposed noise regulations or curfews.

Our existing lease at Denver International Airport was extended and expires in December 2022 with one additional one-year extension option, and in May 2022, we entered into an additional 10-year airport use and lease agreement with the City and County of Denver which includes a new ground-level boarding facility and 14 accompanying gates. We cannot assure you that renewal of the lease will occur on acceptable terms or at all, or that the new lease will not include additional or increased fees. In general, any changes in airport operations could have a material adverse effect on our business, results of operations and financial condition.

Any damage to our reputation or brand image could adversely affect our business or financial results.

Maintaining a good reputation globally is critical to our business. Our reputation or brand image could be adversely impacted by, among other things, any failure to maintain high ethical, social and environmental sustainability practices for all of our operations and activities; our impact on the environment; any inability to maintain our position as “America’s Greenest Airline” including, for example, if another major U.S. airline experiences more average fuel savings than us based on ASMs per fuel gallon consumed or if consumers perceive us to be less “green” than other airlines based on different factors or metrics or by attributing the sustainability practices of our vendors, suppliers and other third parties to us; public pressure from investors or policy groups to change our policies, such as movements to institute a “living wage;” customer perceptions of our advertising campaigns, sponsorship arrangements or marketing programs; customer perceptions of our use of social media; or customer perceptions of statements made by us, our employees and executives, agents or other third parties. In addition, we operate in a highly visible industry that has significant exposure to social media. Negative publicity, including as a result of misconduct by our customers, vendors or employees, can spread rapidly through social media. Should we not respond in a timely and appropriate manner to address negative publicity, our brand and reputation may be significantly harmed. Damage to our reputation or brand image or loss of customer confidence in our services could adversely affect our business and financial results, as well as require additional resources to rebuild our reputation.

In addition, our reputation or brand image could be adversely impacted by any inability to deliver strong operational performance, which we believe helps strengthen our customer loyalty and attract new customers. The DOT publishes statistics regarding measures of customer satisfaction for domestic airlines, including on-time performance and completion factor. Our on-time performance, which measures the percentage of our scheduled flights that were operated by us that were on-time (within 15 minutes) for domestic routes only, was 76.6%, 83.9%, and 73.1% for the years ended December 31, 2021, 2020, and 2019, respectively. Our completion factor, which measures the percentage of our scheduled flights that were completed by us for domestic routes only, whether or not delayed (i.e., not cancelled), was 98.6%, 94.9%, and 98.3% for the years ended December 31, 2021, 2020, and 2019, respectively. The ranges of on-time performance and completion factor for the 10 airlines of significant size in the United States ranged from 68.3% to 90.1% and 96.7% to 99.6%, respectively, and we ranked 7th and 3rd, respectively, for the year ended December 31, 2021. Any sustained inability to maintain or improve our operational performance could result in decreased customer loyalty and, in turn, could significantly harm our brand and reputation and adversely affect our business and financial results.

Moreover, the outbreak and spread of COVID-19 has adversely impacted consumer perceptions of the health and safety of travel, and airline travel in particular, and these negative perceptions, whether or not based in fact, could continue even after the pandemic subsides. Actual or perceived risk of infection on our flights has had, and may continue to have, a material adverse effect on the public’s perception of us, which has harmed, and may continue to harm, our reputation and business. We have taken various measures to reassure our team members and the traveling public of the safety of air travel, such as requiring that facial coverings must be worn by all customers and team members throughout every flight while governmental mask mandates were required and introducing a fogging disinfectant to our already stringent aircraft cleaning and sanitation protocols. We expect that we will continue to incur COVID-19-related costs as we sanitize aircraft, implement additional hygiene-related protocols and take other actions to limit the threat of infection among our employees and passengers. However, we cannot assure you that these or any other actions we might take in response to the COVID-19 pandemic will be sufficient to restore the confidence of consumers in the safety of air travel.

Our reputation and business could be adversely affected in the event of an emergency, accident or similar public incident involving our aircraft or personnel.

We are exposed to potential significant losses and adverse publicity in the event that any of our aircraft or personnel is involved in an emergency, accident, terrorist incident or other similar public incident, which could expose us to significant reputational harm and potential legal liability. In addition, we could face significant costs or lost revenues related to repairs or replacement of a damaged aircraft and its temporary or permanent loss from service. We cannot assure you that we will not be affected by such events or that the amount of our insurance coverage will be adequate in the event such circumstances arise, and any such event could cause a substantial increase in our insurance premiums. In addition, any future emergency, accident or similar incident involving our aircraft or personnel, even if fully covered by insurance or even if it does not involve our airline, may create an adverse public perception about our airline or that the equipment we fly is less safe or reliable than other transportation alternatives, or, in the case of our aircraft, could cause us to perform time-consuming and costly inspections on our aircraft or engines, any of which could have a material adverse effect on our business, results of operations and financial condition.

Negative publicity regarding our customer service could have a material adverse effect on our business, results of operations and financial condition.

Our business strategy includes the differentiation of our brand and product from the other U.S. airlines, including other ULCCs, in order to increase customer loyalty and drive future ticket sales. We intend to accomplish this by continuing to offer passengers dependable customer service. However, in the past, we have experienced a relatively high number of customer complaints related to, among other things, our customer service and reservations and ticketing systems, in addition to complaints related to our COVID-19-related refund policy. We and other airlines have also received complaints regarding the treatment and handling of passengers’ noncompliance with airline policies, including policies implemented in response to the COVID-19 pandemic. Passenger complaints, together with reports of lost baggage, delayed and cancelled flights, and other service issues, are reported to the public by the DOT. The DOT may choose to investigate such customer complaints and this could result in fines. For instance, in 2017 we were fined $0.4 million for certain infractions relating to oversales, rules related to passengers with disabilities and customer service plan rules; $40,000 for certain infractions relating to oversales disclosure and notice requirements, the domestic baggage liability limit rule and customer service plan rules; and $1.5 million relating to lengthy tarmac delays, which was offset by a $0.9 million credit for compensation provided to passengers on the affected flights and other delayed flights. In addition, on March 12, 2021, the DOT advised us that it was in receipt of information indicating that we had failed to comply with certain DOT consumer protection requirements relating to our consumer refund and credit practices and requested that we provide certain information to the DOT. The original DOT request for information and subsequent correspondence and requests have been focused on our refund practices on Frontier-initiated flight cancellations and/or significant schedule changes in flights as a result of the COVID-19 pandemic. We are fully cooperating with the DOT request and the review of this matter is still in process. If we do not meet our customers’ expectations with respect to reliability and service, our brand and product could be negatively impacted, which could result in customers deciding not to fly with us and adversely affect our business and reputation.

We rely on maintaining a high daily aircraft utilization rate to implement our low-cost structure, which makes us especially vulnerable to flight delays, flight cancellations, aircraft unavailability or unplanned reductions in demand such as has been caused by the COVID-19 pandemic.

We have maintained a high daily aircraft utilization rate prior to the COVID-19 pandemic and expect our utilization rate to increase as the U.S. market continues to recover from the pandemic. Our average daily aircraft utilization was 10.8 hours and 7.3 hours for the three months ended March 31, 2022 and 2021, respectively. Aircraft utilization is the average amount of time per day that our aircraft spend carrying passengers. Part of our business strategy is to maximize revenue per aircraft through high daily aircraft utilization, which is achieved, in part, by quick turnaround times at airports so we can fly more hours on average in a day. Aircraft utilization is reduced by delays and cancellations caused by various factors, many of which are beyond our control, including air traffic congestion at airports or other air traffic control problems or outages, labor availability, adverse weather conditions,

increased security measures or breaches in security, international or domestic conflicts, terrorist activity, or other changes in business conditions. A significant portion of our operations are concentrated in markets such as Denver, the Northeast and northern Midwest regions of the United States, which are particularly vulnerable to weather, airport traffic constraints and other delays, particularly in the winter months. In addition, pulling aircraft out of service for unscheduled and scheduled maintenance may materially reduce our average fleet utilization and require that we re-accommodate passengers or seek short-term substitute capacity at increased costs. Further, an unplanned reduction in demand such as has been caused by the COVID-19 pandemic reduces the utilization of our fleet and results in a related increase in unit costs, which may be material. Due to the relatively small size of our fleet, our point-to-point network and high daily aircraft utilization rate, the unexpected unavailability of one or more aircraft and resulting reduced capacity or even a modest decrease in demand could have a material adverse effect on our business, results of operations and financial condition.

We are subject to various environmental and noise laws and regulations, which could have a material adverse effect on our business, results of operations and financial condition.

We are subject to increasingly stringent federal, state, local and foreign laws, regulations and ordinances relating to the protection of the environment and noise, including those relating to emissions to the air, discharges (including storm water discharges) to surface and subsurface waters, safe drinking water and the use, management, disposal and release of, and exposure to, hazardous substances, oils and waste materials. We are or may be subject to new or proposed laws and regulations that may have a direct effect (or indirect effect through our third-party specialists or airport facilities at which we operate) on our operations. In addition, U.S. airport authorities are exploring ways to limit de-icing fluid discharges. Any such existing, future, new or potential laws and regulations could have an adverse impact on our business, results of operations and financial condition.

Similarly, we are subject to environmental laws and regulations that require us to investigate and remediate soil or groundwater to meet certain remediation standards. Under certain laws, generators of waste materials, and current and former owners or operators of facilities, can be subject to liability for investigation and remediation costs at locations that have been identified as requiring response actions. Liability under these laws may be strict, joint and several, meaning that we could be liable for the costs of cleaning up environmental contamination regardless of fault or the amount of wastes directly attributable to us.

In addition, the International Civil Aviation Organization (“ICAO”) and jurisdictions around the world have adopted noise regulations that require all aircraft to comply with noise-level standards, and governmental authorities in several U.S. and foreign cities are considering or have already implemented aircraft noise reduction programs, including the imposition of overnight curfews and limitations on daytime take-offs and landings. Compliance with existing and future environmental laws and regulations, including emissions limitations and more restrictive or widespread noise regulations, that may be applicable to us could require significant expenditures, increase our cost base and have a material adverse effect on our business, results of operations and financial condition, and violations thereof can lead to significant fines and penalties, among other sanctions.

We routinely participate with other airlines in fuel consortia and fuel committees at our airports. The related agreements generally include cost-sharing provisions and environmental indemnities that are generally joint and several among the participating airlines. Any costs (including remediation and spill response costs) incurred by such fuel consortia could also have an adverse impact on our business, results of operations and financial condition.

We are subject to risks associated with climate change, including increased regulation of our CO2 emissions, changing consumer preferences and the potential increased impacts of severe weather events on our operations and infrastructure.

Efforts to transition to a low-carbon future have increased the focus by global, regional and national regulators on climate change and greenhouse gas (“GHG”) emissions, including CO2 emissions. In particular, ICAO has adopted rules, including those pertaining to the Carbon Offset and Reduction Scheme for International Aviation (“CORSIA”), which will require us to address the growth in CO2 emissions of a significant majority of our

international flights. For more information on CORSIA, see “Business—Government Regulation—Environmental Regulation” in our 2021 Annual Report.

At this time, the costs of complying with our future obligations under CORSIA are uncertain, primarily because it is difficult to estimate the return of demand for international air travel as the recovery from the COVID-19 pandemic continues. There is also significant uncertainty with respect to the future supply and price of carbon offset credits and sustainable or lower-carbon aircraft fuels that could allow us to reduce our emissions of CO2. In addition, we will not directly control our CORSIA compliance costs through 2029 because those obligations are based on the growth in emissions of the global aviation sector and begin to incorporate a factor for individual airline operator emissions growth beginning in 2030. Due to the competitive nature of the airline industry and unpredictability of the market for air travel, we can offer no assurance that we may be able to increase our fares, impose surcharges or otherwise increase revenues or decrease other operating costs sufficiently to offset our costs of meeting obligations under CORSIA.

In the event that CORSIA does not come into force as expected, we and other airlines could become subject to an unpredictable and inconsistent array of national or regional emissions restrictions, creating a patchwork of complex regulatory requirements that could affect global competitors differently without offering meaningful aviation environmental improvements. Concerns over climate change are likely to result in continued attempts by municipal, state, regional and federal agencies to adopt requirements or change business environments related to aviation that, if successful, may result in increased costs to the airline industry and us. In addition, several countries and U.S. states have adopted, or are considering adopting, programs, including new taxes, to regulate domestic GHG emissions. Finally, certain airports have adopted, and others could in the future adopt, GHG emission or climate-related goals that could impact our operations or require us to make changes or investments in our infrastructure.

In addition, in January 2021, the U.S. Environmental Protection Agency (“EPA”) adopted GHG emission standards for new aircraft engines, which are aligned with the 2017 ICAO aircraft engine GHG emission standards. Like the ICAO standards, the final EPA standards for new aircraft engines would not apply retroactively to engines on in-service aircraft. The final standards have been challenged by several states and environmental groups, and the Biden administration has announced plans to review these final standards along with others issued by the prior administration. On November 15, 2021, EPA announced that it will not rewrite the existing airplane GHG emissions standards but will press for ambitious new airplane GHG emission standards at international negotiations organized by ICAO in 2022. The outcome of the legal challenge and the development of new airplane GHG emissions standards cannot be predicted at this time. U.S. commitments announced during President Biden’s April 2021 Leaders Summit on Climate include working with other countries on a vision toward reducing the aviation sector’s emissions in a manner consistent with the Biden administration’s 2050 net-zero emissions goal, continued participation in CORSIA and development of sustainable aviation fuels. On September 9, 2021, the Biden administration launched the Sustainable Aviation Fuel Grand Challenge to scale up the production of sustainable aviation fuel, aiming to reduce GHG emissions from aviation by 20% by 2030 and to replace all traditional aviation fuel with sustainable aviation fuel by 2050. Whether these goals will be achieved and the potential effects on our business cannot be predicted at this time.

All such climate change-related regulatory activity and developments may adversely affect our business and financial results by requiring us to reduce our emissions, make capital investments to purchase specific types of equipment or technologies, purchase carbon offset credits, or otherwise incur additional costs related to our emissions. Such activity may also impact us indirectly by increasing our operating costs, including fuel costs.

Growing recognition among consumers of the dangers of climate change may mean some customers choose to fly less frequently or fly on an airline they perceive as operating in a manner that is more sustainable to the climate. Business customers may choose to use alternatives to travel, such as virtual meetings and workspaces. Greater development of high-speed rail in markets now served by short-haul flights could provide passengers with lower-carbon alternatives to flying with us. Our collateral to secure loans, in the form of aircraft, spare parts and airport slots, could lose value as customer demand shifts and economies move to low-carbon alternatives, which may increase our financing cost.

Finally, the potential acute and chronic physical effects of climate change, such as increased frequency and severity of storms, floods, fires, sea-level rise, excessive heat, longer-term changes in weather patterns and other climate-related events, could affect our operations, infrastructure and financial results. Operational impacts, such as the cancelling of flights, could result in loss of revenue. We could incur significant costs to improve the climate resiliency of our infrastructure and otherwise prepare for, respond to, and mitigate such physical effects of climate change. We are not able to predict accurately the materiality of any potential losses or costs associated with the physical effects of climate change.

We are highly dependent upon our cash balances and operating cash flows.

As of March 31, 2022, we had $727 million of total available liquidity in cash and cash equivalents. We will continue to be dependent on our operating cash flows (if any) and cash balances to fund our operations, provide capital reserves and to make scheduled payments on our aircraft-related fixed obligations, including substantial pre-delivery payments (“PDPs”) related to the aircraft we have on order. In addition, we have sought, and may continue to seek, financing from other available sources to fund our operations in order to mitigate the impact of the COVID-19 pandemic on our financial position and operations.

During the fourth quarter of 2020, we amended our PDP facility (the “PDP Financing Facility”) to provide for a deferral of the fixed charge coverage ratio requirement (the “FCCR Test”) until the fourth quarter of 2021. If the FCCR Test is not maintained, we are required to test the loan to collateral ratio for the underlying aircraft in the PDP Financing Facility that are subject to financing (the “LTV Test”) and make any pre-payments or post additional collateral required in order to reduce the loan to value on each aircraft in the PDP Financing Facility that are subject to financing below a ratio threshold. The LTV Test is largely dependent on the appraised fair value of the underlying aircraft subject to financing. LTV Tests performed subsequent to the deferral of the FCCR Test have not resulted in any required pre-payment of the PDP Financing Facility or posting of additional collateral. Additionally, we have also obtained a waiver of relief for the covenant provisions through the second quarter of 2022 related to one of our credit card processors that represents less than 10% of total revenues, which may require future waivers or an amendment to existing covenants to reflect the downturn due to the COVID-19 pandemic.

As of March 31, 2022, we were not subject to any credit card holdbacks, although if we fail to maintain certain liquidity and other financial covenants, our credit card processors have the right to hold back credit card remittances to cover our obligations to them, which would result in a reduction of unrestricted cash that could be material. In addition, while we recently have been able to arrange aircraft lease financing that does not require that we maintain a maintenance reserve account, we are required by some of our aircraft leases, and could in the future be required, to fund reserves in cash in advance for scheduled maintenance to act as collateral for the benefit of lessors. In those circumstances, a portion of our cash is therefore unavailable until after we have completed the scheduled maintenance in accordance with the terms of the operating leases. Based on the age of our fleet and our growth strategy, we expect these maintenance deposits to decrease as we enter into operating leases for newly acquired aircraft that do not require reserves. If we fail to generate sufficient funds from operations to meet our operating cash requirements or do not obtain a line of credit, other borrowing facility or equity financing, we could default on our operating leases and fixed obligations. Our inability to meet our obligations as they become due could have a material adverse effect on our business, results of operations and financial condition.

Our ability to obtain financing or access capital markets may be limited.

We have significant obligations to purchase aircraft and spare engines that we have on order from Airbus, CFM International, an affiliate of General Electric Company, and Pratt & Whitney. As of March 31, 2022, we had a firm obligation to purchase 232 A320neo family aircraft by the end of 2029, five of which had a committed operating lease. We intend to evaluate financing options for the aircraft on order. There are a number of factors that may affect our ability to raise financing or access the capital markets in the future, including our liquidity and credit status, our operating cash flows, market conditions in the airline industry, U.S. and global economic conditions, the general state of the capital markets and the financial position of the major providers of commercial aircraft financing. We cannot assure you that we will be able to source external financing for our planned aircraft acquisitions or for other significant capital needs, and if we are unable to source financing on acceptable terms, or unable to source financing

at all, our business could be materially adversely affected. To the extent we finance our activities with additional debt, we may become subject to financial and other covenants that may restrict our ability to pursue our business strategy or otherwise constrain our growth and operations.

We may be subject to competitive risks due to the long-term nature of our fleet order book and the unproven new engine technology utilized by the aircraft in our order book.

As of March 31, 2022, we had existing aircraft purchase commitments through 2029, all of which are for Airbus A320neo family aircraft. Of the 232 A320neo family aircraft we have committed to purchase by 2029, seven will be equipped with the LEAP engine manufactured by CFM International, an affiliate of General Electric Company, 134 will be equipped with Pratt & Whitney Geared Turbo Fan (“GTF”) engines and we are still evaluating engine options for the remaining 91 aircraft on our order book related to the amendment that was entered into with Airbus in the fourth quarter of 2021. The A320neo family includes next-generation engine technology as well as aerodynamic refinements, large curved sharklets, weight savings, a new aircraft cabin with larger hand luggage spaces and an improved air purification system. While the A320neo family represents the latest step in the modernization of the A320 family of aircraft, the aircraft only entered commercial service in January 2016, and we are one of the first airlines to utilize the A320neo and LEAP engine. As a result, we are subject to those risks commonly associated with the initial introduction of a new aircraft and engine type, including with respect to the A320neo’s actual, sustained fuel efficiency and other projected cost savings, which may not be realized, as well as the reliability and maintenance costs associated with a new aircraft and engine type. In addition, it could take several years to determine whether the reliability and maintenance costs associated with a new aircraft and engine would have a significant impact on our operations. If we are unable to realize the potential competitive advantages we expect to achieve through the implementation of the A320neo aircraft and LEAP or GTF engines into our fleet or if we experience unexpected costs or delays in our operations as a result of such implementation, our business, results of operations and financial condition could be materially adversely affected. Furthermore, as technological evolution occurs in our industry, through the use of composites and other innovations, we may be competitively disadvantaged because we have existing extensive fleet commitments that would prohibit us from adopting new technologies on an expedited basis.

In addition, while our operation of a single family of aircraft provides us with several operational and cost advantages, any FAA directive or other mandatory order relating to our aircraft or engines, including the grounding of any of our aircraft for any reason, could potentially apply to all or substantially all of our fleet, which could materially disrupt our operations and negatively affect our business, results of operations and financial condition.

Our maintenance costs will increase over the near term, we will periodically incur substantial maintenance costs due to the maintenance schedules of our aircraft fleet and obligations to the lessors and we could incur significant maintenance expenses outside of such maintenance schedules in the future.

As of March 31, 2022, the operating leases for four, six, four, eight and twenty aircraft in our fleet were scheduled to terminate during the remainder of 2022, 2023, 2024, 2025 and 2026, respectively. In certain circumstances, such operating leases may be extended. Prior to such aircraft being returned, we will incur costs to restore these aircraft to the condition required by the terms of the underlying operating leases. The amount and timing of these so-called “return conditions” costs can prove unpredictable due to uncertainty regarding the maintenance status of each particular aircraft at the time it is to be returned and it is not unusual for disagreements to ensue between the airline and the leasing company as to the required maintenance on a given aircraft or engine.

In addition, as of March 31, 2022, we had a firm obligation to purchase 232 A320neo family aircraft by the end of 2029. We expect that these new aircraft will require less maintenance when they are first placed in service (sometimes called a “maintenance holiday”) because the aircraft will benefit from manufacturer warranties and also will be able to operate for a significant period of time, generally measured in years, before the most expensive scheduled maintenance obligations, known as heavy maintenance, are first required. Following these new initial maintenance holiday periods, the new aircraft we have an obligation to acquire will require more maintenance as they age and our maintenance and repair expenses for each newly purchased aircraft will be incurred at approximately the same intervals. Moreover, because a large portion of our future fleet will be acquired over a

relatively short period, significant maintenance to be scheduled on each of these planes may occur concurrently with other aircraft acquired around the same time, meaning we may incur our heavy maintenance obligations across large portions of our fleet around the same time. These more significant maintenance activities result in out-of-service periods during which our aircraft are dedicated to maintenance activities and unavailable to fly revenue service.

Outside of scheduled maintenance, we incur from time to time unscheduled maintenance which is not forecast in our operating plan or financial forecasts, and which can impose material unplanned costs and the loss of flight equipment from revenue service for a significant period of time. For example, a single unplanned engine event can require a shop visit costing several million dollars and cause the engine to be out of service for a number of months.

Furthermore, the terms of some of our lease agreements require us to pay maintenance reserves to the lessor in advance of the performance of major maintenance, resulting in our recording significant prepaid deposits on our condensed consolidated balance sheet. In addition, the terms of any lease agreements that we enter into in the future could also require maintenance reserves in excess of our current requirements. We expect scheduled and unscheduled aircraft maintenance expenses to increase over the next several years. Any significant increase in maintenance and repair expenses could have a material adverse effect on our business, results of operations and financial condition. Please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates—Aircraft Leases—Maintenance Reserves and Aircraft Return Costs” filed in our 2021 Annual Report.

We have a significant amount of aircraft-related fixed obligations that could impair our liquidity and thereby harm our business, results of operations and financial condition.

The airline business is capital intensive and, as a result, many airline companies are highly leveraged. As of March 31, 2022, all 112 aircraft in our fleet were financed under operating leases. For the three months ended March 31, 2022 and 2021, we incurred aircraft rent of $128 million and $138 million, respectively, and maintenance costs of $34 million and $26 million, respectively. For the three months ended March 31, 2021, aircraft rent included a $19 million unfavorable impact from the payments of deferral arrangements with our lessors due to the COVID-19 pandemic. For the three months ended March 31, 2022, there were no deferrals or payments, and therefore no impact to aircraft rent within the condensed consolidated statements of operations, as we had paid back the entire amount of our aircraft and engine rent deferrals, which were recognized as aircraft rent within the condensed consolidated statements of operations as the payments were made. As of March 31, 2022 and December 31, 2021, we had future operating lease obligations of approximately $2,410 million and $2,435 million, respectively, and future principal debt obligations of $355 million and $423 million, respectively. For the three months ended March 31, 2022 and 2021, we made cash payments for interest related to debt of $2 million and $1 million, respectively. In addition, we have significant obligations for aircraft and spare engines that we have ordered from Airbus as well as CFM International and Pratt & Whitney for delivery over the next several years.

Our ability to pay the fixed costs associated with our contractual obligations will depend on our operating performance, cash flow and our ability to secure adequate financing, which will in turn depend on, among other things, the success of our current business strategy, fuel price volatility, any significant weakening or improvement in the U.S. economy, availability and cost of financing, as well as general economic and political conditions and other factors that are, to some extent, beyond our control. The amount of our aircraft-related fixed obligations and our obligations under our other debt arrangements could have a material adverse effect on our business, results of operations and financial condition and could:

•require a substantial portion of cash flow from operations be used for operating lease and maintenance deposit payments, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;

•limit our ability to make required PDPs, including those payable to our aircraft and engine manufacturers for our aircraft and spare engines on order;

•limit our ability to obtain additional financing to support our expansion plans and for working capital and other purposes on acceptable terms or at all;

•make it more difficult for us to pay our other obligations as they become due during adverse general economic and market industry conditions because any related decrease in revenues could cause us to not have sufficient cash flows from operations to make our scheduled payments;

•reduce our flexibility in planning for, or reacting to, changes in our business and the airline industry and, consequently, place us at a competitive disadvantage to our competitors with lower fixed payment obligations; and

•cause us to lose access to one or more aircraft and forfeit our maintenance and other deposits if we are unable to make our required aircraft lease rental payments and our lessors exercise their remedies under the lease agreement including cross default provisions in certain of our leases.

A failure to pay our operating lease, debt, fixed costs, and other obligations or a breach of our contractual obligations could result in a variety of adverse consequences, including the exercise of remedies by our creditors and lessors. In such a situation, it is unlikely that we would be able to cure our breach, fulfill our obligations, make required lease payments or otherwise cover our fixed costs, which could have a material adverse effect on our business, results of operations and financial condition.

We rely on third-party specialists and other commercial partners to perform functions integral to our operations.

We have historically entered into agreements with third-party specialists to furnish certain facilities and services required for our operations, including ground handling, catering, passenger handling, engineering, maintenance, refueling, reservations and airport facilities, as well as administrative and support services. In response to the COVID-19 pandemic, we have increased our reliance on such third parties. As the U.S. market continues to recover from the pandemic, we are likely to enter into similar service agreements in new markets we decide to enter, and we cannot assure you that we will be able to obtain the necessary services at acceptable rates. In addition, certain third-party vendors may have difficulty hiring or retaining sufficient talent to meet their obligations to us due to the impact of the COVID-19 pandemic including, among other things, employee response to any potential vaccine mandates.

Although we seek to monitor the performance of third parties that furnish certain facilities or provide us with our ground handling, catering, passenger handling, engineering, maintenance, refueling, reservations and airport facilities, the efficiency, timeliness and quality of contract performance by third-party specialists are often beyond our control, and any failure by our third-party specialists to perform up to our expectations may have an adverse impact on our business, reputation with customers, our brand and our operations. In addition, we could experience a significant business disruption if we were to change vendors or if an existing provider ceased to be able to serve us. We expect to be dependent on such third-party arrangements for the foreseeable future.

We rely on third-party distribution channels to distribute a portion of our airline tickets.

We rely on third-party distribution channels, including those provided by or through Global Distribution Systems (“GDSs”), conventional travel agents and online travel agents (“OTAs”) to distribute a portion of our airline tickets, and we expect in the future to rely on these channels to collect a portion of our non-fare revenues. These distribution channels are more expensive and at present have less functionality in respect of non-fare revenues than those we operate ourselves, such as our website. Certain of these distribution channels also effectively restrict the manner in which we distribute our products. To remain competitive, we will need to successfully manage our distribution costs and rights, and improve the functionality of third-party distribution channels, while maintaining an industry-competitive cost structure. Negotiations with key GDSs and OTAs designed to manage our costs, increase our distribution flexibility and improve functionality could be contentious, could result in diminished or less favorable distribution of our tickets and may not provide the functionality we require to maximize non-fare revenues. In addition, in the last several years there has been significant consolidation among GDSs and OTAs, including the acquisition by Expedia of both Orbitz and Travelocity, and the acquisition by Amadeus of Navitaire (the reservations system that we use). This consolidation and any further consolidation could affect our ability to manage our distribution costs due to a reduction in competition or other industry factors. Any inability to manage such costs, rights and functionality at a competitive level or any material diminishment in the distribution of our tickets could have a material adverse effect on our competitive position and our results of operations. Moreover, our

ability to compete in the markets we serve may be threatened by changes in technology or other factors that may make our existing third-party sales channels impractical, uncompetitive or obsolete.

We rely heavily on technology and automated systems to operate our business, and any failure of these technologies or systems or any failure on our part to implement any new technologies or systems could materially adversely affect our business.

We are highly dependent on technology and computer systems and networks to operate our business. These technologies and systems include our computerized airline reservation system provided by Navitaire, now a unit of Amadeus, flight operations systems, telecommunications systems, mobile app, airline website, maintenance systems and check-in kiosks. In order for our operations to work efficiently, our website and reservation system must be able to accommodate a high volume of traffic, maintain secure information and deliver flight information. The Navitaire reservations system, which is hosted and maintained under a long-term contract by a third-party specialist, is critical to our ability to issue, track and accept tickets, conduct check-in, board and manage our passengers through the airports we serve and provide us with access to GDSs, which enlarge our pool of potential passengers. There are many instances in the past where a reservations system malfunctioned, whether due to the fault of the system provider or the airline, with a highly adverse effect on the airline’s operations, and such a malfunction has in the past, and could in the future, occur on our system, or in connection with any system upgrade or migration in the future. We also rely on third-party specialists to maintain our flight operations systems, and if those systems are not functioning, we could experience service disruptions, which could result in the loss of important data, increase our expenses, decrease our operational performance and temporarily stall our operations.

Any failure of the technologies and systems we use could materially adversely affect our business. In particular, if our reservation system fails or experiences interruptions, and we are unable to book seats for a period of time, we could lose a significant amount of revenue as customers book seats on other airlines, and our reputation could be harmed. In addition, replacement technologies and systems for any service we currently utilize that experiences failures or interruptions may not be readily available on a timely basis, at competitive rates or at all. Furthermore, our current technologies and systems are heavily integrated with our day-to-day operations and any transition to a new technology or system could be complex and time-consuming. In the event that one or more of our primary technology or systems vendors fails to perform, and a replacement system is not available or if we fail to implement a replacement system in a timely and efficient manner, our business could be materially adversely affected.

Unauthorized use, unauthorized incursions or user exploitation of our information technology infrastructure could compromise the personally identifiable information of our passengers, prospective passengers or personnel, and other sensitive information and expose us to liability, damage our reputation and have a material adverse effect on our business, results of operations and financial condition.

In the processing of our customer transactions and as part of our ordinary business operations, we and certain of our third-party specialists collect, process, transmit and store a large volume of personally identifiable information of our passengers, prospective passengers or personnel, including email addresses, home addresses, financial data such as credit and debit card information and other sensitive information. The security of the systems and network where we and our third-party specialists store this data is a critical element of our business, and these systems and our network may be vulnerable to cyberattacks and other security issues, including threats potentially involving criminal hackers, hacktivists, state-sponsored actors, corporate espionage, employee malfeasance and human or technological error. Threats to cybersecurity have increased with the sophistication of malicious actors, and we must manage those evolving risks. We have been the target of cybersecurity attacks in the past and expect that we will continue to be in the future. Recently, several high-profile companies have experienced significant data breaches and ransom attacks, which have caused those companies to suffer substantial financial and reputational harm. Failure to appropriately address these issues could also give rise to potentially material legal risks and liabilities.

A significant cybersecurity incident could result in a range of potentially material negative consequences for us, including lost revenue; unauthorized access to, disclosure, modification, misuse, loss or destruction of company systems or data; theft of sensitive, regulated or confidential data, such as personal identifying information or our intellectual property; the loss of functionality of critical systems through ransomware, denial of service or other

attacks; and business delays, service or system disruptions, damage to equipment and injury to persons or property. The costs and operational consequences of defending against, preparing for, responding to and remediating an incident may be substantial. As cybersecurity threats become more frequent, intense and sophisticated, costs of proactive defense measures are increasing. Further, we could be exposed to litigation, regulatory enforcement or other legal action as a result of an incident, carrying the potential for damages, fines, sanctions or other penalties, as well as injunctive relief requiring costly compliance measures. A cybersecurity incident could also impact our brand, harm our reputation and adversely impact our relationship with our customers, employees and stockholders. Additionally, any material failure by us or our third-party specialists to maintain compliance with the Payment Card Industry security requirements or to rectify a data security issue may result in fines and restrictions on our ability to accept credit and debit cards as a form of payment. While we have taken precautions to avoid an unauthorized incursion of our computer systems, we cannot assure you that our precautions are either adequate or implemented properly to prevent and detect a data breach or other cybersecurity incident and its adverse financial and reputational consequences to our business.

We are also subject to increasing legislative, regulatory and customer focus on privacy issues and data security in the United States and abroad. The compromise of our technology systems resulting in the loss, disclosure, misappropriation of or access to the personally identifiable information of our passengers, prospective passengers or personnel could result in governmental investigation, civil liability or regulatory penalties under laws protecting the privacy of personal information, any or all of which could disrupt our operations and have a material adverse effect on our business, results of operations and financial condition. In addition, a number of our commercial partners, including credit card companies, have imposed data security standards on us, and these standards continue to evolve. We will continue our efforts to meet our privacy and data security obligations; however, it is possible that certain new obligations may be difficult to meet and could increase our costs.

We depend on a sole-source supplier for our aircraft and two suppliers for our engines.

A critical cost-saving element of our business strategy is to operate a single-family aircraft fleet; however, our dependence on the Airbus A320 family aircraft for all of our aircraft and on CFM International and Pratt & Whitney for our engines makes us vulnerable to any design defects, mechanical problems or other technical or regulatory issues associated with this aircraft type or these engines. In the event of any actual or suspected design defects or mechanical problems with the Airbus A320 family aircraft or CFM International or Pratt & Whitney engines, whether involving our aircraft or that of another airline, we may choose, or be required, to suspend or restrict the use of our aircraft. Our business could also be materially adversely affected if the public avoids flying on our aircraft due to an adverse perception of the Airbus A320 family aircraft or CFM International or Pratt & Whitney engines, whether because of safety concerns or other problems, real or perceived, or in the event of an accident involving such aircraft or engines. Separately, if any of Airbus, CFM International or Pratt & Whitney becomes unable to perform its contractual obligations and we must lease or purchase aircraft or engines from another supplier, we would incur substantial transition costs, including expenses related to acquiring new aircraft, engines, spare parts, maintenance facilities and training activities, and we would lose the cost benefits from our current single-fleet composition, any of which could have a material adverse effect on our business, results of operations and financial condition. These risks may be exacerbated by the long-term nature of our fleet and order book and the unproven new engine technology to be utilized by the aircraft in our order book. See also “—We may be subject to competitive risks due to the long-term nature of our fleet order book and the unproven new engine technology utilized by the aircraft in our order book.”

Although we have significantly reconfigured our network since 2013, our business remains dependent on select large markets and increases in competition or congestion or a reduction in demand for air travel in this market would harm our business.

We are highly dependent on select markets where we maintain a large presence, with 27% and 22% of our flights during the three months ended March 31, 2022 having Orlando International Airport and Denver International Airport as either their origin or destination, respectively. We operate at Orlando International Airport under an operating lease which expires in 2024 and we primarily operate out of Concourse A at Denver International Airport under an operating lease which expires in December 2022 with one additional one-year extension option,

and in May 2022, we entered into an additional 10-year airport use and lease agreement with the City and County of Denver which includes a new ground-level boarding facility and 14 accompanying gates. We have experienced an increase in flight delays and cancellations at these airports due to airport congestion, which has adversely affected our operating performance and results of operations. We have also experienced increased competition at Denver International Airport since 2017 from carriers adding flights to and from Denver. Additionally, flight operations in both Orlando and Denver can face extreme weather challenges which, at times, has resulted in severe disruptions in our operation and the occurrence of material costs as a consequence of such disruptions.

Our business could be further harmed by an increase in the amount of direct competition we face in the select markets we operate in or by continued or increased congestion, delays or cancellations. Our business would also be harmed by any circumstances causing a reduction in demand for air transportation in the select markets we operate in, such as adverse changes in local economic conditions, health concerns, adverse weather conditions, negative public perception of those markets, terrorist attacks or significant price or tax increases linked to increases in airport access costs and fees imposed on passengers.

We are subject to extensive regulation by the FAA, the DOT, TSA, U.S. Customs and Border Protection and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business, results of operations and financial condition.

Airlines are subject to extensive regulatory and legal compliance requirements, both domestically and internationally, that involve significant costs. In the last several years, the U.S. Congress has passed laws and the FAA, the DOT and TSA have issued regulations, orders, rulings and guidance relating to the operation, safety and security of airlines and consumer protections that have required significant expenditures. We expect to continue to incur expenses in connection with complying with such laws and government regulations, orders, rulings and guidance. Additional laws, regulations, taxes and increased airport rates and charges have been proposed from time to time that could significantly increase the cost of airline operations or reduce the demand for air travel. If adopted, these measures could have the effect of raising ticket prices, reducing revenue and increasing costs. For example, the DOT has broad authority over airlines and their consumer and competitive practices, and has used this authority to issue numerous regulations and pursue enforcement actions, including rules and fines relating to the handling of unfair or deceptive practices and unfair methods of competition including undisclosed display bias, lengthy tarmac delays, chronically delayed flights, consumer notice and disclosure requirements, consumer complaints, airline advertising and marketing practices, codeshare disclosure, oversales and involuntary denied boarding process and compensation, ticket refunds, liability for loss, delay or damage to baggage, customer service commitments, contracts of carriage, customer service commitments and the transportation of passengers with disabilities. Among these is the series of Enhanced Airline Passenger Protection rules issued by the DOT. In addition, the FAA Reauthorization Act of 2018, signed into law on October 5, 2018, provided for several new requirements and rulemakings related to airlines, including but not limited to: (i) prohibition on voice communication cell phone use during certain flights, (ii) insecticide use disclosures, (iii) new training policy best practices for training regarding racial, ethnic, and religious non-discrimination, (iv) training on human trafficking for certain staff, (v) departure gate stroller check-in, (vi) the protection of pets on airplanes and service animal standards, (vii) requirements to refund promptly to passengers any ancillary fees paid for services not received, (viii) consumer complaint process improvements, (ix) pregnant passenger assistance, (x) restrictions on the ability to deny a revenue passenger permission to board or involuntarily remove such passenger from the aircraft, (xi) minimum customer service standards for large ticket agents, (xii) information publishing requirements for widespread disruptions and passenger rights, (xiii) submission of plans pertaining to employee and contractor training consistent with the Airline Passengers with Disabilities Bill of Rights, (xiv) ensuring assistance for passengers with disabilities, (xv) flight attendant duty period limitations and rest requirements, including submission of a fatigue risk management plan, (xvi) submission of policies concerning passenger sexual misconduct, (xvii) development of an Employee Assault Prevention and Response Plan related to the customer service agents, (xviii) increased penalties available related to harm to passengers with disabilities or damage to wheelchairs or mobility aids, and (xix) minimum dimensions for passenger seats. Furthermore, in 2019, the FAA published an advance notice of proposed rulemaking regarding flight attendant duty-period limitations and rest requirements. The DOT also published a notice of proposed rulemaking in January 2020 regarding the accessibility features of lavatories and onboard wheelchair requirements on certain single-aisle aircraft with an FAA certificated maximum capacity of 125 seats or more, training flight

attendants to proficiency on an annual basis to provide assistance in transporting qualified individuals with disabilities to and from the lavatory from the aircraft seat, and providing certain information on request to qualified individuals with a disability or persons inquiring on their behalf, on the carrier’s website and in printed or electronic form on the aircraft, concerning the accessibility of aircraft lavatories. In July 2021, the DOT issued a notice of proposed rulemaking requiring airlines to refund checked bag fees for delayed bags if they are not delivered to the passenger within a specified number of hours and refunding ancillary fees for services related to air travel that passengers did not receive. The DOT also recently published final rules regarding traveling by air with service animals, defining unfair or deceptive practices, clarifying that the maximum amount of denied boarding compensation that a carrier may provide to a passenger denied boarding involuntarily is not limited, prohibiting airlines from involuntarily denying boarding to a passenger after the passenger’s boarding pass has been collected or scanned and the passenger has boarded (subject to safety and security exceptions), raising the liability limits for denied boarding compensation and raising the liability limit for mishandled baggage in domestic air transportation. In addition, the FAA issued its final regulations governing pilot rest periods and work hours for all passenger airlines certificated under Part 121 of the Federal Aviation Regulations. The rule known as FAR Part 117, which became effective January 4, 2014, impacts the required amount and timing of rest periods for pilots between work assignments and modifies duty and rest requirements based on the time of day, number of scheduled segments, time zones and other factors. In addition, the U.S. Congress enacted a law and the FAA issued regulations requiring U.S. airline pilots to have a minimum number of hours as a pilot in order to qualify for an Air Transport Pilot certificate, which all pilots on U.S. airlines must obtain. Compliance with these rules may increase our costs, while failure to remain in full compliance with these rules may subject us to fines or other enforcement action. FAR Part 117 and the minimum pilot hour requirements may also reduce our ability to meet flight crew staffing requirements. We cannot assure you that compliance with these and other laws, regulations, orders, rulings and guidance will not have a material adverse effect on our business, results of operations and financial condition.

In addition, the TSA mandates the federalization of certain airport security procedures and imposes additional security requirements on airports and airlines, some of which is funded by a security fee imposed on passengers and collected by airlines. We cannot forecast what additional security and safety requirements may be imposed in the future or the costs or revenue impact that would be associated with complying with such requirements.

Our ability to operate as an airline is dependent on our obtaining and maintaining authorizations issued to us by the DOT and the FAA. The FAA from time to time issues directives and other mandatory orders relating to, among other things, operating aircraft, the grounding of aircraft, maintenance and inspection of aircraft, installation of new safety-related items, and removal and replacement of aircraft parts that have failed or may fail in the future. These requirements can be issued with little or no notice, can impact our ability to efficiently or fully utilize our aircraft, and could result in the temporary grounding of aircraft types altogether, such as the March 2019 grounding of the Boeing 737 MAX fleet. A decision by the FAA to ground, or require time-consuming inspections of or maintenance on, our aircraft, for any reason, could negatively affect our business, results of operations and financial condition. Federal law requires that air carriers operating scheduled service be continuously “fit, willing and able” to provide the services for which they are licensed. Our “fitness” is monitored by the DOT, which considers managerial competence, operations, finances and compliance record. In addition, under federal law, we must be a U.S. citizen (as determined under applicable law). Please see “Business—Foreign Ownership” in our 2021 Annual Report. While the DOT has seldom revoked a carrier’s certification for lack of fitness, such an occurrence would render it impossible for us to continue operating as an airline. The DOT may also institute investigations or administrative proceedings against airlines for violations of regulations. For instance, in 2017 we were fined $0.4 million for certain infractions relating to oversales, rules related to passengers with disabilities and customer service plan rules, $40,000 for certain infractions relating to oversales disclosure and notice requirements, the domestic baggage liability limit rule and customer service plan rules; and $1.5 million relating to lengthy tarmac delays, which was offset by a $0.9 million credit for compensation provided to passengers on the affected flights and other delayed flights. In addition, on March 12, 2021, the DOT advised us that it was in receipt of information indicating that we had failed to comply with certain DOT consumer protection requirements relating to our consumer refund and credit practices and requested that we provide certain information to the DOT. The original DOT request for information and subsequent correspondence and requests have been focused on our refund practices on Company-initiated flight cancellations and/or significant schedule changes in flights as a result of the COVID-19 pandemic. We are fully cooperating with the DOT request and the review of this matter is still in process.

International routes are regulated by air transport agreements and related agreements between the United States and foreign governments. Our ability to operate international routes is subject to change, as the applicable agreements between the United States and foreign governments may be amended from time to time. Our access to new international markets may be limited by the applicable air transport agreements between the U.S. and foreign governments and our ability to obtain the necessary authority from the U.S. and foreign governments to fly the international routes. In addition, our operations in foreign countries are subject to regulation by foreign governments and our business may be affected by changes in law and future actions taken by such governments, including granting or withdrawal of government approvals, airport slots and restrictions on competitive practices. We are subject to numerous foreign regulations in the countries outside the United States where we currently provide service. If we are not able to comply with this complex regulatory regime, our business could be significantly harmed. Please see “Business—Government Regulation” in our 2021 Annual Report.

Changes in legislation, regulation and government policy have affected, and may in the future have a material adverse effect on, our business, results of operations, cash flows and financial condition.

Changes in, and uncertainty with respect to, legislation, regulation and government policy at the local, state or federal level have affected, and may in the future significantly impact, our business and the airline industry. Specific legislative and regulatory proposals that could have a material impact on us in the future include, but are not limited to, infrastructure renewal programs; changes to operating and maintenance requirements and immigration and security policy and requirements; modifications to international trade policy, including withdrawing from trade agreements and imposing tariffs; changes to consumer protection laws; public company reporting requirements; environmental regulation; and antitrust enforcement. Any such changes may make it more difficult and/or more expensive for us to obtain new aircraft or engines and parts to maintain existing aircraft or engines or make it less profitable or prevent us from flying to or from some of the destinations we currently serve. To the extent that any such changes have a negative impact on us or the airline industry in general, including as a result of related uncertainty, these changes may materially impact our business, results of operations, cash flows and financial condition.

New U.S. tax legislation may adversely affect our business, results of operations, cash flows and financial condition.

The U.S. government may enact significant changes to the taxation of business entities including, among others, an increase in the corporate income tax rate, the imposition of minimum taxes or surtaxes on certain types of income, significant changes to the taxation of income derived from international operations and an addition of further limitations on the deductibility of business interest. While certain draft legislation was publicly released in 2021, the likelihood of these changes being enacted or implemented is unclear. If such changes are enacted or implemented, we are currently unable to predict the ultimate impact on our business and therefore there can be no assurance that our business will not be adversely affected.

If we are unable to attract and retain qualified personnel at reasonable costs or fail to maintain our company culture, our business, results of operations and financial condition could be harmed.

Our business is labor intensive. We require large numbers of pilots, flight attendants, maintenance technicians and other personnel. We compete against other U.S. airlines for pilots, mechanics and other skilled labor and certain U.S. airlines offer wage and benefit packages exceeding ours. The airline industry has from time to time experienced a shortage of qualified personnel. In particular, as more pilots in the industry approach mandatory retirement age, the U.S. airline industry is being affected by a pilot shortage. As is common with most of our competitors, we have faced considerable turnover of our employees. These factors have caused us recently to maintain a larger workforce than is immediately necessary for our planned operations in order to maintain network reliability and support planned growth in light of the challenges of hiring and retaining employees under current economic conditions. As a result of the foregoing, there can be no assurance that we will be able to attract or retain qualified personnel and we may be required to increase wages and/or benefits in order to do so. In addition, we may lose personnel due to the impact of the COVID-19 pandemic including, among other things, employee response to the related health and safety initiatives or to a return to office. Legally required vaccine mandates have been imposed and have resulted in

multiple unresolved court challenges, some of which remain ongoing. We cannot predict what policies we may elect to or be required, to implement in the future, or the effect thereof on our business, including whether the imposition of a mandatory vaccination requirement could cause us to lose, or experience difficulties hiring, qualified personnel. Further, we may lose executives as a result of compensation restrictions imposed under the CARES Act. Such restrictions may present retention challenges in the case of executives presented with alternative, non-airline opportunities or with opportunities from airlines that are not subject to such restrictions because they did not participate in the CARES Act Programs or because the restrictions have lifted through time or repayments of the loan programs. If we are unable to hire, train and retain qualified employees, our business could be harmed and we may be unable to implement our growth plans.

In addition, as we hire more people and grow, we believe it may be increasingly challenging to continue to hire people who will maintain our company culture. Our company culture, which we believe is one of our competitive strengths, is important to providing dependable customer service and having a productive, accountable workforce that helps keep our costs low. As we continue to grow, we may be unable to identify, hire or retain enough people who meet the above criteria, including those in management or other key positions. Our company culture could otherwise be adversely affected by our growing operations and geographic diversity. If we fail to maintain the strength of our company culture, our competitive ability and our business, results of operations and financial condition could be harmed.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Under the Internal Revenue Code of 1986, as amended (the “Code”), for U.S. federal income tax purposes, a corporation is generally allowed a deduction for net operating losses (“NOLs”) carried over from prior taxable years. As of December 31, 2021 we had approximately $30 million of federal NOLs available to reduce future federal taxable income. Under current tax law, our federal NOL carryforwards do not expire, but the deductibility of such NOL carryforwards is limited to 80% of our taxable income for taxable years beginning on or after January 1, 2021. We also had approximately $10 million of NOL carryforwards to reduce future state taxable income as of December 31, 2021, which will expire, if not utilized, from two years to having no expiration depending on the state the NOL is attributed to, and $7 million of foreign net operating losses, which expire in nine years. As a result of our assessment over the future realizability of these NOLs as of December 31, 2021, we recorded a $7 million valuation allowance related to our foreign NOL and a $1 million valuation allowance related to our state NOLs as these are more likely than not to not be realized given the short expiry periods in foreign and certain state jurisdictions.

Realization of these NOL carryforwards depends on our future taxable income and there is a risk that, due to the COVID-19 pandemic and other economic factors, our existing NOL carryforwards could expire before we can generate sufficient taxable income to use them. If our NOL carryforwards expire unused (to the extent subject to expiration) and are unavailable to offset future taxable income, this could materially adversely affect our results of operations and financial condition.

In addition, under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership by significant stockholders or groups of stockholders over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change taxable income or income tax liabilities may be limited. We may experience ownership changes in the future because of, among other things, shifts in our stock ownership, many of which are outside of our control. If we were to experience an ownership change for purposes of Section 382 of the Code, our ability to use our NOL carryforwards and other tax attributes to offset future U.S. federal taxable income or income tax liabilities may become subject to limitations, which could result in increased future tax liability to us. Similar rules and limitations may apply under state and foreign tax laws.

Any tariffs imposed on commercial aircraft and related parts imported from outside the United States may have a material adverse effect on our fleet, business, results of operations and financial condition.

Certain of the products and services that we purchase, including our aircraft and related parts, are sourced from suppliers located in foreign countries, and the imposition of new tariffs, or any increase in existing tariffs, by the

U.S. government on the importation of such products or services could materially increase the amounts we pay for them. In early October 2019, the World Trade Organization ruled that the United States could impose $7.5 billion in retaliatory tariffs in response to illegal European Union subsidies to Airbus. On October 18, 2019, the United States imposed these tariffs on certain imports from the European Union, including a 10% tariff on new commercial aircraft. In February 2020, the United States announced an increase to this tariff from 10% to 15%. These tariffs apply to aircraft that we are already contractually obligated to purchase. In June 2021, the United States and the European Union announced an agreement to suspend the imposition of the foregoing tariffs on commercial aircraft and related parts for five years. Any reimposition of these tariffs could substantially increase the cost of, among other things, imported new Airbus aircraft and parts required to service our Airbus fleet which, in turn, could have a material adverse effect on our business, results of operations and financial condition.

Our business could be materially adversely affected if we lose the services of our key personnel.

Our success depends to a significant extent upon the efforts and abilities of our senior management team and key financial and operating personnel. In particular, we depend on the services of our senior management team, particularly Barry L. Biffle, our President and Chief Executive Officer, and James G. Dempsey, our Executive Vice President and Chief Financial Officer. Competition for highly qualified personnel is intense, and the loss of any executive officer, senior manager, or other key employee without an adequate replacement, or the inability to attract new qualified personnel could have a material adverse effect on our business, results of operations and financial condition. We do not maintain key-man life insurance on our management team.

We rely on our private equity sponsor.

Our majority stockholder is presently an investment fund managed by Indigo, an affiliate of Indigo Partners, a private equity fund with significant expertise in the ultra low-cost airline business. This expertise has been available to us through the representatives Indigo has on our board of directors and through a Professional Services Agreement that was put in place in connection with the 2013 acquisition from Republic Airways Holdings, Inc. and pursuant to which we are charged a fee by Indigo Partners of approximately $375,000 per quarter, plus expenses. Several members of our board of directors are also affiliated with Indigo Partners and we pay each of them an annual fee as compensation. Our engagement of Indigo Partners pursuant to the Professional Services Agreement will continue until the date that Indigo Partners and its affiliates own less than approximately 19.8 million shares of our common stock. Indigo Partners may nonetheless elect to reduce its ownership in our company or reduce its involvement on our board of directors, which could reduce or eliminate the benefits we have historically achieved through our relationship with Indigo Partners, such as management expertise, industry knowledge and volume purchasing. See “—Risks Related to Owning Our Common Stock—Indigo’s current control of the Company severely limits the ability of our stockholders to influence matters requiring stockholder approval and could adversely affect our other stockholders and the interests of Indigo could conflict with the interests of other stockholders.”

Our quarterly results of operations fluctuate due to a number of factors, including seasonality.

We expect our quarterly results of operations to continue to fluctuate due to a number of factors, including actions by our competitors, price changes in aircraft fuel and the timing and amount of maintenance expenses, as well as the impacts of the COVID-19 pandemic. As a result of these and other factors, quarter-to-quarter comparisons of our results of operations and month-to-month comparisons of our key operating statistics may not be reliable indicators of our future performance. In addition, seasonality may cause our quarterly and monthly results to fluctuate since passengers tend to fly more during the summer months and less in the winter months, apart from the holiday season. We cannot assure you that we will find profitable markets in which to operate during the winter

season. Such periods of low demand for air travel during the winter months could have a material adverse effect on our business, results of operations and financial condition.

Our lack of membership in a marketing alliance or codeshare arrangements (other than with Volaris) could harm our business and competitive position.

Many airlines, including the domestic legacy network airlines (American Airlines, Delta Air Lines and United Airlines), have marketing alliances with other airlines, under which they market and advertise their status as marketing alliance partners. These alliances, such as Oneworld, SkyTeam and Star Alliance, generally provide for codesharing, frequent flyer program reciprocity, coordinated scheduling of flights to permit convenient connections and other joint marketing activities. In addition, certain of these alliances involve highly integrated antitrust immunized joint ventures. Such arrangements permit an airline to market flights operated by other alliance members as its own. This increases the destinations, connections and frequencies offered by the airline and provides an opportunity to increase traffic on that airline’s segment of flights connecting with alliance partners. We currently do not have any marketing alliances or codeshare arrangements with U.S. or foreign airlines, other than the codeshare arrangement we entered into with Volaris in 2018. Our lack of membership in any other marketing alliances and codeshare arrangements puts us at a competitive disadvantage to traditional network carriers who are able to attract passengers through more widespread alliances, particularly on international routes, and that disadvantage may result in a material adverse effect on our business, results of operations and financial condition.

Risks Related to Owning Our Common Stock

The market price of our common stock may be volatile, which could cause the value of an investment in our stock to decline.

The market price of our common stock may fluctuate substantially due to a variety of factors, many of which are beyond our control, including:

•announcements concerning our competitors, the airline industry or the economy in general;

•developments with respect to the COVID-19 pandemic, and government restrictions and mandates related thereto;

•strategic actions by us or our competitors, such as acquisitions or restructurings;

•media reports and publications about the safety of our aircraft or the type of aircraft we operate;

•new regulatory pronouncements and changes in regulatory guidelines;

•changes in the price or availability of aircraft fuel;

•announcements concerning the availability of the type of aircraft we operate;

•general and industry-specific economic conditions;

•changes in financial estimates or recommendations by securities analysts or failure to meet analysts’ performance expectations;

•sales of our common stock or other actions by investors with significant shareholdings, including sales by our principal stockholders;

•trading strategies related to changes in fuel or oil prices; and

•general market, political and other economic conditions.

The stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of particular companies. Broad market fluctuations may materially adversely affect the trading price of our common stock.

In the past, stockholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Any similar litigation against us could result in substantial costs, divert management’s attention and resources and have a material adverse effect on our business, results of operations and financial condition.

If securities or industry analysts do not publish research or reports about our business or publish negative reports about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities and industry analysts may publish about us or our business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, the trading price of our common stock would likely decline. If one or more of these analysts ceases to cover our company or fails to publish reports on us regularly, demand for our stock could decrease, which may cause the trading price of our common stock and the trading volume of our common stock to decline.

The issuance or sale of shares of our common stock, or rights to acquire shares of our common stock, or the exercise of the PSP warrants, PSP2 warrants, PSP3 warrants or Treasury Loan warrants issued to the Treasury, could depress the trading price of our common stock.

We may conduct future offerings of our common stock, preferred stock or other securities that are convertible into, or exercisable for, our common stock to finance our operations or fund acquisitions, or for other purposes. In connection with our participation in the PSP, PSP2 and PSP3, we issued warrants to the Treasury which are exercisable for up to an aggregate of 759,850 shares of our common stock.

In connection with the $150 million borrowing from the Treasury Loan, which was repaid in full on February 2, 2022, we issued warrants to the Treasury which are exercisable for up to 2,358,090 shares of our common stock. Further, we reserve shares of our common stock for future issuance under our equity incentive plans, which shares are eligible for sale in the public market to the extent permitted by the provisions of various agreements and, to the extent held by affiliates, the volume and manner of sale restrictions of Rule 144. If these additional shares are sold, or if it is perceived that they will be sold, into the public market, the price of our common stock could decline substantially. If we issue additional shares of our common stock or rights to acquire shares of our common stock, if any of our existing stockholders sell a substantial amount of our common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our common stock could significantly decline. In addition, the issuance of additional shares of common stock would dilute the ownership interests of our existing common stockholders.

The value of our common stock may be materially adversely affected by additional issuances of common stock or preferred stock by us or sales by our principal stockholder.

Any future issuances or sales of our common stock by us will be dilutive to our existing common stockholders. We had 217,499,881 shares of common stock outstanding as of March 31, 2022. All of the shares of common stock sold in our initial public offering are freely tradable without restrictions or further registration under the Securities Act. An investment fund managed by Indigo, the holder of approximately 178.8 million shares of our common stock as of March 31, 2022, is entitled to rights with respect to registration of all such shares under the Securities Act pursuant to a registration rights agreement. Sales of substantial amounts of our common stock in the public or private market, a perception in the market that such sales could occur, or the issuance of securities exercisable or convertible into our common stock, could adversely affect the prevailing price of our common stock.

Indigo’s current control of the Company severely limits the ability of our stockholders to influence matters requiring stockholder approval and could adversely affect our other stockholders and the interests of Indigo could conflict with the interests of other stockholders.

As of the date of this report, an investment fund managed by Indigo beneficially owns approximately 82.2% of our outstanding common stock.

As a result, Indigo will be able to exert a significant degree of influence or actual control over our management and affairs and over matters requiring stockholder approval, including the election of directors, a merger, consolidation or sale of all or substantially all of our assets and other significant business or corporate transactions.

Until such time as Indigo and its affiliates beneficially own shares of our common stock representing less than a majority of the voting rights of our common stock, Indigo will have the ability to take stockholder action by written consent without calling a stockholder meeting and to approve amendments to our amended and restated certificate of incorporation and amended and restated bylaws and to take other actions without the vote of any other stockholder. As a result, Indigo will have the ability to control all such matters affecting us, including:

•the composition of our board of directors and, through our board of directors, any determination with respect to our business plans and policies;

•the compensation of our named executive officers;

•our acquisition or disposition of assets;

•our financing activities, including the issuance of additional equity securities;

•any determinations with respect to mergers, acquisitions and other business combinations;

•corporate opportunities that may be suitable for us and Indigo;

•the payment of dividends on our common stock; and

•the number of shares available for issuance under our stock plans for our existing and prospective employees.

This concentrated control will limit the ability of other stockholders to influence corporate matters and, as a result, we may take actions that our other stockholders do not view as beneficial. Indigo’s voting control may also discourage or block transactions involving a change of control of the Company, including transactions in which you, as a stockholder, might otherwise receive a premium for your shares over the then-current market price. For example, this concentration of ownership could have the effect of delaying or preventing a change in control or otherwise discouraging a potential acquirer from attempting to obtain control of us, which in turn could cause the market price of our common stock to decline or prevent our stockholders from realizing a premium over the market price for their common stock. Moreover, Indigo is not prohibited from selling a controlling interest in us to a third party and may do so without your approval and without providing for a purchase of your shares of common stock. Accordingly, your shares of common stock may be worth less than they would be if Indigo did not maintain voting control over us.

In addition, the interests of Indigo could conflict with the interests of other stockholders. As of March 31, 2022, investment funds managed by Indigo Partners hold approximately 18% of the total outstanding common stock shares of Volaris, and two of our directors, William A. Franke and Brian H. Franke, are members of the board of directors of Volaris, with Brian H. Franke serving as chair since April 2020. We entered into a codeshare arrangement with Volaris in January 2018. As of March 31, 2022, we did not compete directly with Volaris on any of our routes. However, there can be no assurances that we will not compete directly with Volaris in the future. Furthermore, neither Indigo Partners, its portfolio companies, funds or other affiliates, nor any of their officers, directors, agents, stockholders, members or current or future partners will have any duty to refrain from engaging, directly or indirectly, in the same business activities, similar business activities or lines of business in which we operate. See “—Our amended and restated certificate of incorporation contains a provision renouncing our interest and expectancy in certain corporate opportunities.”

Our anti-takeover provisions may delay or prevent a change of control, which could adversely affect the price of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws may make it difficult to remove our board of directors and management and may discourage or delay “change of control” transactions, which could adversely affect the price of our common stock. These provisions include, among others:

•our board of directors is divided into three classes, with each class serving for a staggered three-year term, which prevents stockholders from electing an entirely new board of directors at an annual meeting;

•no cumulative voting in the election of directors, which prevents the minority stockholders from electing director candidates;

•the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

•from and after such time as Indigo and its affiliates no longer hold a majority of the voting rights of our common stock, actions to be taken by our stockholders may only be affected at an annual or special meeting of our stockholders and not by written consent;

•from and after such time as Indigo and its affiliates no longer hold a majority of the voting rights of our common stock, special meetings of our stockholders may be called only by the Chairman of the Board or by our corporate secretary at the direction of our board of directors;

•advance notice procedures that stockholders, other than Indigo for so long as it and its affiliates hold a majority of the voting rights of our common stock, must comply with in order to nominate candidates to our board of directors and propose matters to be brought before an annual meeting of our stockholders may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company;

•from and after such time as Indigo and its affiliates hold less than a majority of the voting rights of our common stock, a majority stockholder vote is required for removal of a director only for cause (and a director may only be removed for cause), and a 66 2⁄3% stockholder vote is required for the amendment, repeal or modification of certain provisions of our certificate of incorporation and bylaws; and

•our board of directors may, without stockholder approval, issue series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of our common stock or could also be used as a method of discouraging, delaying or preventing a change of control.

Certain anti-takeover provisions under Delaware law also apply to us. While we have elected not to be subject to the provisions of Section 203 of the Delaware General Corporation Law (“DGCL”) in our amended and restated certificate of incorporation, such certificate of incorporation provides that in the event Indigo Partners and its affiliates cease to beneficially own at least 15% of the then-outstanding shares of our voting common stock, we will automatically become subject to Section 203 of the DGCL to the extent applicable. Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its voting stock unless the holder has held the stock for three years or, among other things, the board of directors has approved the transaction.

Our amended and restated certificate of incorporation and amended and restated bylaws provide for an exclusive forum in the Court of Chancery of the State of Delaware for certain disputes between us and our stockholders, and that the federal district courts of the United States will be the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that: (i) unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if such court does not have subject matter jurisdiction thereof, the federal district court of the State of Delaware) will, to the fullest extent permitted by law, be the sole and exclusive forum for: (A) any derivative action or proceeding brought on our behalf, (B) any action asserting a claim for or based on a breach of a fiduciary duty owed by any of our current or former directors, officers, other employees, agents or stockholders to us or our stockholders, including without limitation a claim alleging the aiding and abetting of such a breach of fiduciary duty, (C) any action asserting a claim against us or any of our current or former directors, officers, employees, agents or stockholders arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or amended and restated bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (D) any action asserting a claim related to or involving us that is governed by the internal affairs doctrine; (ii) unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States will, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause or causes of action arising under the Securities Act, and the rules and regulations promulgated thereunder, including all causes of action asserted against any defendant to such complaint; (iii) any person or entity purchasing or otherwise acquiring or holding any interest in our shares of capital stock will be deemed to have notice of and consented to these provisions; and (iv) failure to enforce the foregoing provisions would cause us irreparable harm, and we will be entitled to equitable relief, including injunctive relief and specific

performance, to enforce the foregoing provisions. This provision is intended to benefit and may be enforced by us, our officers and directors, the underwriters to any offering giving rise to such complaint and any other professional entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering. This exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction. Nothing in our amended and restated certificate of incorporation or amended and restated bylaws precludes stockholders that assert claims under the Exchange Act from bringing such claims in federal court to the extent that the Exchange Act confers exclusive federal jurisdiction over such claims, subject to applicable law.

We believe these provisions may benefit us by providing increased consistency in the application of Delaware law and federal securities laws by chancellors and judges, as applicable, particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule relative to other forums and protection against the burdens of multi-forum litigation. If a court were to find the choice of forum provision that is contained in our amended and restated certificate of incorporation or amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could materially adversely affect our business, results of operations, and financial condition. For example, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce such a forum selection provision as written in connection with claims arising under the Securities Act.

The choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our current or former directors, officers, other employees, agents, or stockholders, which may result in increased costs or discourage a stockholder from bringing such claims.

Our amended and restated certificate of incorporation contains a provision renouncing our interest and expectancy in certain corporate opportunities.

Our amended and restated certificate of incorporation provides for the allocation of certain corporate opportunities between us and Indigo. Under these provisions, neither Indigo, its portfolio companies, funds or other affiliates, nor any of their agents, stockholders, members, partners, officers, directors and employees will have any duty to refrain from engaging, directly or indirectly, in the same business activities, similar business activities or lines of business in which we operate. For instance, a director of our company who also serves as a stockholder, member, partner, officer, director or employee of Indigo or any of its portfolio companies, funds or other affiliates may pursue certain acquisitions or other opportunities that may be complementary to our business and, as a result, such acquisitions or other opportunities may not be available to us. These potential conflicts of interest could have a material adverse effect on our business, results of operations or financial condition, if attractive corporate opportunities are allocated by Indigo to itself or its portfolio companies, funds or other affiliates instead of to us. In addition, our amended and restated certificate of incorporation provides that we shall indemnify each the aforementioned parties in the event of any claims for breach of fiduciary or other duties brought in connection with such other opportunities. The terms of our amended and restated certificate of incorporation are more fully described in the Description of the Registrant’s Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934, which is filed as Exhibit 4.1 to our 2021 Annual Report.

Our amended and restated certificate of incorporation and amended and restated bylaws include provisions limiting ownership, control and voting by non-U.S. citizens.

To comply with restrictions imposed by federal law on foreign ownership and control of U.S. airlines, our amended and restated certificate of incorporation and amended and restated bylaws restrict ownership, voting and control of shares of our common stock by non-U.S. citizens. The restrictions imposed by federal law and DOT policy require that we must be owned and controlled by U.S. citizens, that no more than 25.0% of our voting stock be owned or controlled, directly or indirectly, by persons or entities who are not U.S. citizens, as defined in 49 U.S.C. § 40102(a)(15), that our president and at least two-thirds of the members of our board of directors and other

managing officers be U.S. citizens, and that we be under the actual control of U.S. citizens. In addition, and subject to the limitation that no more than 25.0% of our voting stock be owned or controlled, directly or indirectly, by persons or entities who are not U.S. citizens, up to 49% of our outstanding stock may be owned or controlled, directly or indirectly, by persons or entities who are not U.S. citizens but only if those non-U.S. citizens are from countries that have entered into “open skies” air transport agreements with the U.S. which allow unrestricted access between the United States and the applicable foreign country and to points beyond the foreign country on flights serving the foreign country. Our amended and restated certificate of incorporation and amended and restated bylaws provide that the failure of non-U.S. citizens to register their shares on a separate stock record, which we refer to as the “foreign stock record,” would result in a loss of their voting rights in the event and to the extent that the aggregate foreign ownership of the outstanding common stock exceeds the foreign ownership restrictions imposed by federal law. Our amended and restated bylaws further provide that no shares of our common stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law. If it is determined that the amount registered in the foreign stock record exceeds the foreign ownership restrictions imposed by federal law, shares will be removed from the foreign stock record, resulting in the loss of voting rights, in reverse chronological order based on the date of registration therein, until the number of shares registered therein does not exceed the foreign ownership restrictions imposed by federal law. We believe we are currently in compliance with these ownership restrictions. See “Business—Foreign Ownership” in our 2021 Annual Report and the Description of the Registrant’s Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934, which is filed as Exhibit 4.1 to our 2021 Annual Report.

We are a “controlled company” within the meaning of the Nasdaq Stock Market rules, and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements. Our stockholders do not have the same protections afforded to stockholders of companies that are subject to such requirements.

As of the date of this report, Indigo controls approximately 82.2% of our outstanding common stock. As a result, we are a “controlled company” within the meaning of the Nasdaq Stock Market rules and exempt from the obligation to comply with certain corporate governance requirements, including the requirements that a majority of our board of directors consists of “independent directors,” as defined under the rules of the Nasdaq Stock Market, and that we have a compensation committee and a nominating and corporate governance committee that are composed entirely of independent directors. These exemptions do not modify the requirement for a fully independent audit committee, which is permitted to be phased-in as follows: (i) one independent committee member at the time of our initial public offering; (ii) a majority of independent committee members within 90 days of our initial public offering; and (iii) all independent committee members within one year of our initial public offering. Similarly, once we are no longer a “controlled company,” we must comply with the independent board committee requirements as they relate to the compensation committee and the nominating and corporate governance committee, on the same phase-in schedule as set forth above, with the trigger date being the date we are no longer a “controlled company” as opposed to our initial public offering date. Additionally, we will have 12 months from the date we cease to be a “controlled company” to have a majority of independent directors on our board of directors.

If we utilize the “controlled company” exemption, you will not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the Nasdaq Stock Market. Our status as a controlled company could make our common stock less attractive to some investors or otherwise adversely affect its trading price.

We are a holding company and rely on dividends, distributions, and other payments, advances, and transfers of funds from our subsidiaries to meet our obligations.

We are a holding company that does not conduct any business operations of our own. As a result, we are largely dependent upon cash dividends and distributions and other transfers, including for payments in respect of indebtedness, at the holding company level from our subsidiaries to meet our obligations. The agreements governing the indebtedness of our subsidiaries, including the CARES Act, impose restrictions on our subsidiaries’ ability to pay dividend distributions or other transfers to us. Each of our subsidiaries is a distinct legal entity, and under certain circumstances legal and contractual restrictions may limit our ability to obtain cash from them. The deterioration of

the earnings from, or other available assets of, our subsidiaries for any reason could also limit or impair their ability to pay dividends or other distributions to us.

As of the date of this filing, we are prohibited from making repurchases of our common stock and paying dividends on our common stock by operation of restrictions imposed by the CARES Act and the PSP Extension Law. Following the end of those restrictions, we cannot guarantee that we will repurchase shares of our common stock or pay dividends on our common stock, or that our capital deployment program will enhance long-term stockholder value. Our capital deployment program could increase the volatility of the price of our common stock and diminish our cash reserves.

In connection with our receipt of payroll support under the PSP, PSP2 and PSP3 and acceptance of the Treasury Loan Agreement, we agreed not to repurchase shares of our common stock or pay out dividends on common stock until February 2, 2023. Any future determination to pay dividends will be at the discretion of our board of directors and will depend on our results of operations, financial condition, capital requirements, restrictions contained in current or future financing instruments, business prospects and such other factors as our board of directors deems relevant.

General Risk Factors

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members or executive officers.

As a public company, we incur significant legal, accounting and other expenses that we did not previously incur as a private company, including costs associated with public company reporting requirements. We also have incurred and will incur costs associated with the Sarbanes-Oxley Act of 2002, as amended, the Dodd-Frank Wall Street Reform and Consumer Protection Act, related rules implemented or to be implemented by the SEC and the listing rules of the Nasdaq Stock Market. In recent years, the expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly, although we are currently unable to estimate these costs with any degree of certainty. These laws and regulations could also make it more costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or our board committees or as our executive officers and may divert management’s attention. Furthermore, if we are unable to satisfy our obligations as a public company, our common stock could be delisted, which could restrict our access to capital, and we could be subject to fines, sanctions and other regulatory action and potentially civil litigation.

We will be required to assess our internal control over financial reporting on an annual basis, and any future adverse findings from such assessment could result in a loss of investor confidence in our financial reports, result in significant expenses to remediate any internal control deficiencies and have a material adverse effect on our business, results of operations and financial condition.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended, and beginning with our Annual Report on Form 10-K for the year ending December 31, 2022, our management will be required to report on, and our independent registered public accounting firm to attest to, the effectiveness of our internal control over financial reporting. The rules governing management’s assessment of our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. We are currently in the process of reviewing, documenting and testing our internal control over financial reporting. We may encounter problems or delays in completing the implementation of any changes necessary to make a favorable assessment of our internal control over financial reporting. In connection with the attestation process by our independent registered public accounting firm, we may encounter problems or delays in implementing any requested improvements and receiving a favorable attestation. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, we will not be able to conclude on an ongoing basis that we have effective internal control over financial

reporting in accordance with Section 404. If we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our condensed consolidated financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the Nasdaq Stock Market, regulatory investigations, civil or criminal sanctions and litigation, any of which could have a material adverse effect on our business, results of operations and financial condition.

We may become involved in litigation that could have a material adverse effect on our business, results of operations and financial condition.

We have in the past been, are currently, and may in the future become, involved in private actions, class actions, investigations and various other legal proceedings, including from employees, commercial partners, customers, competitors and government agencies, among others. Such claims could involve discrimination (for example, based on gender, age, race or religious affiliation), sexual harassment, privacy, patent, commercial, product liability, whistleblower and other litigation and claims, and governmental and other regulatory investigations and proceedings.

Further, from time to time, our employees may bring lawsuits against us regarding discrimination, sexual harassment, labor, ERISA, disability claims and employment and other claims. For example, we currently face gender discrimination claims brought by certain of our employees. In recent years, companies have experienced a general increase in the number of discrimination and harassment claims. Coupled with the expansion of social media platforms that allow individuals with access to a broad audience, these claims have had a significant negative impact on some businesses.

Also, in recent years, there has been significant litigation in the United States and abroad involving patents and other intellectual property rights. We have in the past faced, and may face in the future, claims by third parties that we infringe upon their intellectual property rights.

Any claims asserted against us or our management, regardless of merit or eventual outcome, could be harmful to our reputation and brand and have an adverse impact on our relationships with our customers, commercial partners and other third parties and could lead to additional related claims. Such matters can be time-consuming, divert management’s attention and resources, cause us to incur significant expenses or liability and/or require us to change our business practices. Because of the potential risks, expenses and uncertainties of litigation, we may, from time to time, settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, we cannot assure you that the results of any of these actions will not have a material adverse effect on our business, results of operations and financial condition.
