Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of Spirit Airlines, Inc. (“Spirit”) and its consolidated subsidiaries (the "Company").

These unaudited condensed consolidated financial statements 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 audited annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission for Form 10-Q. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements of the Company and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities and Exchange Commission on February 8, 2022.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect both the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates.

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 as demand is generally greater in the second and third quarters of each year. However, beginning in early 2020, as a result of the COVID-19 pandemic, demand has not always been in line with such trends. The air transportation business is volatile and highly affected by economic cycles and trends.

2. Merger

On February 5, 2022, Spirit Airlines entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Frontier Group Holdings, Inc., a Delaware corporation (“Frontier”), and Top Gun Acquisition Corp., a Delaware corporation and a direct, wholly owned subsidiary of Frontier (“Merger Sub”), pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit Airlines, with Spirit Airlines continuing as the surviving entity (the “Merger”). As a result of the Merger, each existing share of Spirit Airlines’ common stock will be converted into the right to receive (i) $2.13 in cash, without interest and (ii) 1.9126 shares of Frontier’s common stock (“Frontier Common Stock”), par value $0.001 per share. Upon consummation of the Merger, existing shareholders of Spirit Airlines will own approximately 48.5% of the outstanding shares of Frontier on a fully diluted basis.

Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among other things, (1) approval of the Merger Agreement by Spirit Airlines’ stockholders, (2) receipt of applicable regulatory approvals, including approvals from the U.S. Federal Communications Commission (“FCC”), U.S. Federal Aviation Administration (“FAA”) and the U.S. Department of Transportation (“DOT”) and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; (4) the effectiveness of the registration statement to be filed by Frontier and Spirit Airlines with the SEC pursuant to the Merger Agreement; (5) the authorization and approval for listing on NASDAQ of the shares of Frontier Common Stock to be issued to holders of Spirit Airlines’ common stock in the Merger; and (6) the absence of any material adverse effect (as defined in the Merger Agreement) on either Spirit Airlines or Frontier.

The Merger Agreement contains certain customary termination rights for Spirit Airlines and Frontier, including, without limitation, a right for either party to terminate if the Merger is not consummated on or before February 5, 2023, subject to certain extensions if needed to obtain regulatory approvals. Upon the termination of the Merger Agreement under specified circumstances, Spirit Airlines will be required to pay Frontier a breakup fee of $94.2 million. The Merger Agreement also provides the methodology by which certain expenses will be borne.

On April 5, 2022, the Company announced that it received an unsolicited proposal from JetBlue Airways (JetBlue) to acquire all of the outstanding shares of Spirit Airlines’ common stock in an all-cash transaction for $33.00 per share. After consulting with financial and legal advisors, the Company's Board of Directors determined that JetBlue’s proposal could

reasonably be likely to lead to a "Superior Proposal" as defined in the merger agreement with Frontier and evaluated the proposal in accordance with the terms of the merger agreement.

On May 2, 2022, the Company announced that its Board of Directors, in consultation with outside financial and legal advisors, unanimously determined that the unsolicited proposal received from JetBlue does not constitute a "Superior Proposal" due to an unacceptable level of deal completion risk. The Company will continue to advance toward completing the transaction with Frontier, which is expected to close in the second half of 2022. The transaction is subject to customary closing conditions, including completion of the ongoing regulatory review process and approval of the Company's stockholders.

3. Revenue

Operating revenues are comprised of passenger revenues, which includes fare and non-fare revenues, and other revenues. The following table shows disaggregated operating revenues for the three months ended March 31, 2022 and 2021.

The Company defers the amount for award travel obligations as part of loyalty deferred revenue within air traffic liability ("ATL") on the Company's condensed consolidated balance sheets and recognizes loyalty travel awards in passenger revenues as points are used for travel or expire unused.

As of March 31, 2022 and December 31, 2021, the Company had ATL balances of $558.3 million and $382.3 million, respectively. Substantially all of the Company's ATL is expected to be recognized within 12 months of the respective balance sheet date.

Loyalty Programs

The Company operates the Spirit Saver$ Club® , which is a subscription-based loyalty program that allows members access to unpublished, extra-low fares as well as discounted prices on bags and seats, exclusive offers on hotels, rental cars and other travel necessities, shortcut boarding and security, and "Flight Flex" flight modification product. The Company also operates the Free Spirit loyalty program, which attracts members and partners and builds customer loyalty for the Company by offering a variety of awards, benefits and services. Free Spirit loyalty program members earn and accrue points for dollars spent on Spirit for flights and other non-fare services as well as services from non-air partners such as retail merchants, hotels or car rental companies or by making purchases with credit cards issued by partner banks and financial services providers. Points earned and accrued by Free Spirit loyalty program members can be redeemed for travel awards such as free (other than taxes and government-imposed fees), discounted or upgraded travel.

4. Loss on Disposal

During the three months ended March 31, 2022, the Company recorded $11.6 million in loss on disposal of assets in the condensed consolidated statement of operations. This loss on disposal primarily consisted of $6.6 million related to the impairment of one spare engine which was damaged beyond economic repair and $4.3 million related to the loss on three aircraft sale leaseback transactions completed during the first quarter of 2022.

During the three months ended March 31, 2021, the Company recorded $1.1 million in loss on disposal of assets in the condensed consolidated statement of operations related to the sale of auxiliary power units ("APUs") and disposal of excess and obsolete inventory.

5. Special Charges (Credits)

During the three months ended March 31, 2022, the Company recorded $11.1 million within special charges (credits) on the Company's condensed consolidated statements of operations, in legal, advisory and other fees related to the Merger Agreement with Frontier executed during the first quarter of 2022. In addition, as part of the Merger Agreement, the Company implemented an employee retention bonus program. The target retention bonus will be paid to the Company's employees upon the successful close of the merger. In the event the merger fails or is abandoned, 50% of the target retention bonus will be paid to the Company's employees at the termination date of the merger. During the three months ended March 31, 2022, the Company recorded $4.5 million within special charges (credits) on the Company's condensed consolidated statements of operations, related to the Company's retention bonus program.

During the three months ended March 31, 2021, the Company recorded $156.5 million, net of related costs, within special credits on the Company’s condensed consolidated statements of operations related to the grant component of the PSP2 agreement with the Treasury. These funds were used exclusively to pay for salaries, wages and benefits for the Company's Team Members through March 31, 2021.

In addition, during the three months ended March 31, 2021, the Company recorded $21.3 million related to the CARES Act Employee Retention credit within special credits on the Company’s condensed consolidated statements of operation. These special credits were partially offset by $0.8 million in special charges recorded during the three months ended March 31, 2021. The $0.8 million was related to salaries, wages and benefits paid to rehired employees, previously terminated with the Company's involuntary employee separation program, in compliance with the restrictions of PSP2.

6. Loss per Share

The following table sets forth the computation of basic and diluted loss per common share:


	Three Months Ended March 31,

7. Short-term Investment Securities

The Company's short-term investment securities are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of 12 months or less. These securities are stated at fair value within current assets on the Company's condensed consolidated balance sheets. Realized gains and losses on sales of investments, if any, are reflected in non-operating income (expense) in the condensed consolidated statements of operations.

As of March 31, 2022 and December 31, 2021, the Company had $106.0 million and $106.3 million in short-term available-for-sale investment securities, respectively.

9.Leases

The Company leases aircraft, engines, airport terminals, maintenance and training facilities, aircraft hangars, commercial real estate, and office and computer equipment, among other items. Certain of these leases include provisions for variable lease payments which are based on several factors, including, but not limited to, relative leased square footage, enplaned passengers, and airports’ annual operating budgets. Due to the variable nature of the rates, these leases are not recorded on the Company's condensed consolidated balance sheets as a right-of-use asset and lease liability. Lease terms are generally 8 years to 18 years for aircraft and up to 99 years for other leased equipment and property.

During the three months ended March 31, 2022, the Company took delivery of three aircraft under sale leaseback transactions and one spare engine purchased with cash. As of March 31, 2022, the Company had a fleet consisting of 176 A320 family aircraft. As of March 31, 2022, the Company had 70 aircraft financed under operating leases with lease term expirations between 2023 and 2040. In addition, the Company owned 105 aircraft of which 33 were purchased off lease and were unencumbered as of March 31, 2022. The Company also had one aircraft recorded as a failed sale leaseback. The related finance obligation is recorded within long-term debt in the Company's condensed consolidated balance sheets. Refer to Note 12, Debt and Other Obligations for additional information. The related asset is recorded within flight equipment in the Company's condensed consolidated balance sheets. As of March 31, 2022, the Company also had 12 spare engines financed under operating leases with lease term expiration dates ranging from 2022 to 2033 and owned 21 spare engines, all of which, as of March 31, 2022, were pledged as collateral under the Company's revolving credit facility maturing in 2024.

Some of the Company’s aircraft and engine master lease agreements provide that the Company pays maintenance reserves to aircraft lessors to be held as collateral in advance of the Company’s required performance of major maintenance activities. A

majority of these maintenance reserve payments are calculated based on a utilization measure, such as flight hours or cycles, while some maintenance reserve payments are fixed, time-based contractual amounts. Maintenance reserve payments that are probable of being recovered when the Company performs qualifying maintenance are recorded in aircraft maintenance deposits on the Company's condensed consolidated balance sheets. Fixed maintenance reserve payments that are not probable of being recovered are considered lease payments and are included in the right-of-use asset and lease liability. Maintenance reserve payments that are based on a utilization measure and are not probable of being recovered are considered variable lease payments that are recognized when they are probable of being incurred and are not included in the right-of-use asset and lease liability.

Some of the master lease agreements do not require that the Company pay maintenance reserves so long as the Company's cash balance does not fall below a certain level. As of March 31, 2022, the Company was in full compliance with those requirements and does not anticipate having to pay reserves related to these master leases in the future.

Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the Company's aircraft and spare engine lease agreements recognized on a straight-line basis. Aircraft rent expense also includes maintenance reserves paid to aircraft lessors in advance of the performance of major maintenance activities that are not probable of being reimbursed and probable lease return condition obligations.

Under the terms of the lease agreements, the Company will continue to operate and maintain the aircraft. Payments under the majority of the lease agreements are fixed for the term of the lease. The lease agreements contain standard termination events, including termination upon a breach of the Company's obligations to make rental payments and upon any other material breach of the Company's obligations under the leases, and standard maintenance and return condition provisions. These return provisions are evaluated at inception of the lease and throughout the lease terms and are accounted for as either fixed or variable lease payments (depending on the nature of the lease return condition) when it is probable that such amounts will be incurred. When determining probability and estimated cost of lease return obligations, there are various other factors that need to be considered such as the contractual terms of the lease, the ability to swap engines or other aircraft components, current condition of the aircraft, the age of the aircraft at lease expiration, utilization of engines and other components, the extent of repairs needed at return, return locations, current configuration of the aircraft and cost of repairs and materials at the time of return. Management assesses the factors listed above and the need to accrue lease return costs throughout the lease as facts and circumstances warrant an assessment. The Company expects lease return costs and unrecoverable maintenance deposits will increase as individual aircraft lease agreements approach their respective termination dates and the Company begins to accrue the estimated cost of return conditions for the corresponding aircraft. Upon a termination of the lease due to a breach by the Company, the Company would be liable for standard contractual damages, possibly including damages suffered by the lessor in connection with remarketing the aircraft or while the aircraft is not leased to another party.

As of March 31, 2022, the Company's finance lease obligations primarily relate to the lease of computer equipment used by the Company's flight crew and office equipment. Payments under these finance lease agreements are fixed for terms ranging from 4 to 5 years. Finance lease assets are recorded within property and equipment and the related liabilities are recorded within long-term debt and finance leases in the Company's condensed consolidated balance sheets.

During the fourth quarter of 2019, the Company purchased an 8.5-acre parcel of land for $41.0 million and entered into a 99-year lease agreement for the lease of a 2.6-acre parcel of land, in Dania Beach, Florida, where the Company is building its new headquarters campus. During January 2022, the Company began building its new headquarters campus with an expected completion during the fourth quarter 2023. In connection with the lease agreement, the Company is also expected to build a 200-unit residential building. The 8.5-acre parcel of land is capitalized within ground property and equipment on the Company's condensed consolidated balance sheets. The 99-year lease was determined to be an operating lease and is recorded within operating lease right-of-use asset and operating lease liability on the Company's condensed consolidated balance sheets. Operating lease commitments related to this lease are included in the table below within property facility leases.

The following table provides details of the Company's future minimum lease payments under finance lease liabilities and operating lease liabilities recorded on the Company's condensed consolidated balance sheets as of March 31, 2022. The table does not include commitments that are contingent on events or other factors that are currently uncertain or unknown.

10. Commitments and Contingencies

Aircraft-Related Commitments and Financing Arrangements

The Company’s contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies. As of March 31, 2022, the Company's total firm aircraft orders consisted of 117 A320 family aircraft with Airbus, including A319neos, A320neos and A321neos, with deliveries expected through 2027. Out of these 117 aircraft, the Company has 14 aircraft scheduled for delivery in the remainder of 2022 and 17 aircraft scheduled for delivery in 2023.

During the third quarter of 2021, the Company entered into an Engine Purchase Support Agreement which requires the Company to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of March 31, 2022, the Company is committed to purchase 15 PW1100G-JM spare engines, with deliveries through 2027. As of March 31, 2022, purchase commitments for these aircraft and engines, including estimated amounts for contractual price escalations and pre-delivery payments, are expected to be $727.3 million for the remainder of 2022, $906.9 million in 2023, $999.4 million in 2024, $1,060.7 million in 2025, $1,349.9 million in 2026, and $872.8 million in 2027 and beyond. During the third quarter of 2019, the United States announced its decision to levy tariffs on certain imports from the European Union, including commercial aircraft and related parts. These tariffs include aircraft and other parts that the Company is already contractually obligated to purchase including those reflected above. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend reciprocal tariffs on large civilian aircraft for five years, pending discussions to resolve their trade dispute.

In addition to the aircraft purchase agreement, as of March 31, 2022, the Company has agreements in place for 40 A320neos and A321neos to be financed through direct leases with third-party lessors with deliveries scheduled from the remainder of 2022 through 2024. As of March 31, 2022, the Company had secured financing for 14 aircraft, scheduled for delivery from Airbus through the remainder of 2022, which will be financed through sale leaseback transactions. The contractual purchase amounts for these aircraft are included within the purchase commitments above. As of March 31, 2022, the Company did not have financing commitments in place for the remaining 103 Airbus aircraft on firm order through 2027. However, the Company has a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement signed in the fourth quarter of 2019. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing.

As of March 31, 2022, aircraft rent commitments for future aircraft deliveries to be financed under direct leases from third-party lessors and sale leaseback transactions are expected to be approximately $30.2 million for the remainder of 2022, $124.9 million in 2023, $202.3 million in 2024, $231.2 million in 2025, $231.2 million in 2026, and $1,954.2 million in 2027 and beyond.

Interest commitments related to the secured debt financing of 73 delivered aircraft as of March 31, 2022 are $56.7 million for the remainder of 2022, $64.6 million in 2023, $53.3 million in 2024, $45.8 million in 2025, $38.3 million in 2026, and $90.3 million in 2027 and beyond. As of March 31, 2022, interest commitments related to the Company's 8.00% senior secured notes, convertible debt financing, unsecured term loans and revolving credit facility are $37.9 million for the remainder of 2022, $48.5 million in 2023, $48.5 million in 2024, $45.5 million in 2025, $5.9 million in 2026, and $14.0 million in 2027 and beyond. For principal commitments related to the Company's debt financing, refer to Note 12, Debt and Other Obligations.

The Company is contractually obligated to pay the following minimum guaranteed payments for its reservation system, construction commitments related to its new headquarters campus and other miscellaneous subscriptions and services as of March 31, 2022: $29.6 million for the remainder of 2022, $21.1 million in 2023, $17.4 million in 2024, $17.4 million in 2025, $16.8 million in 2026, and $18.8 million in 2027 and thereafter. During the first quarter of 2018, the Company entered into a contract renewal with its reservation system provider which expires in 2028.

Litigation and Assessments

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 believes the ultimate outcome of such lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on its financial position, liquidity or results of operations. In making a determination regarding accruals, using available information, the Company evaluates the likelihood of an unfavorable outcome in legal or regulatory proceedings and assessments to which the Company is a party and records a loss contingency when it is probable a liability has been incurred and the amount of the loss can be reasonably estimated. These subjective determinations are based on the status of such legal or regulatory proceedings, the merits of the Company's defenses, and consultation with legal counsel. Actual outcomes of these legal and regulatory proceedings may materially differ from the Company's current estimates. It is possible that resolution of one or more of the legal matters currently pending or threatened could result in losses material to the Company's consolidated results of operations, liquidity, or financial condition.

Following an audit by the Internal Revenue Service (IRS) related to the collection of federal excise taxes on optional passenger seat selection charges covering the period of the second quarter 2018 through the fourth quarter 2020, on March 31, 2022, the Company was assessed $34.9 million. The Company believes a loss in this matter is not probable and has not recognized a loss contingency.

Credit Card Processing Arrangements

The Company has agreements with organizations that process credit card transactions arising from the purchase of air travel, baggage charges, and other ancillary services by customers. As is standard in the airline industry, the Company's contractual arrangements with credit card processors permit them, under certain circumstances, to retain a holdback or other collateral, which the Company records as restricted cash, when future air travel and other future services are purchased via credit card transactions. The required holdback is the percentage of the Company's overall credit card sales that its credit card processors hold to cover refunds to customers if the Company fails to fulfill its flight obligations.

The Company's credit card processors do not require the Company to maintain cash collateral provided that the Company satisfies certain liquidity and other financial covenants. Failure to meet these covenants would provide the processors the right to place a holdback resulting in a commensurate reduction of unrestricted cash. As of March 31, 2022 and December 31, 2021, the Company's credit card processors were holding back no remittances.

The maximum potential exposure to cash holdbacks by the Company's credit card processors, based upon advance ticket sales and Spirit Saver$ Club® memberships as of March 31, 2022 and December 31, 2021, was $632.6 million and $371.8 million, respectively.

Employees

The Company has 5 union-represented employee groups that together represented approximately 80% of all employees as of March 31, 2022. The table below sets forth the Company's employee groups and status of the collective bargaining agreements as of March 31, 2022.

The Company's passenger service agents are represented by the TWU, but the representation applies only to the Company's Fort Lauderdale station where the Company has direct employees in the passenger service classification. The Company and the TWU began meeting in late October 2018 to negotiate an initial collective bargaining agreement. During February 2022, the Company reached a tentative agreement with the TWU. The Company's passenger service agents ratified the five-year agreement on February 21, 2022.

In February 2021, the Company entered into a Letter of Agreement with the AFA-CWA to change the amendable date of the collective bargaining agreement from May 4, 2021 to September 1, 2021. All other terms of the collective bargaining agreement remained the same. In June 2021, the AFA-CWA notified the Company, as required by the Railway Labor Act, that it intends to submit proposed changes to the collective bargaining agreement covering the Company’s flight attendants. The Company and the AFA-CWA began the negotiation sessions on September 27, 2021. As of March 31, 2022, the Company continued to negotiate with the AFA-CWA.

11.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.

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 the Company’s financial assets and liabilities.

Long-Term Debt

The estimated fair value of the Company's secured notes, term loan debt agreements and revolving credit facilities have been determined to be Level 3 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 estimated fair value of the Company's publicly and non-publicly held EETC debt agreements and the Company's convertible notes has been determined to be Level 2 as the Company utilizes quoted market prices in markets with low trading volumes to estimate the fair value of its Level 2 long-term debt.

The carrying amounts and estimated fair values of the Company's long-term debt at March 31, 2022 and December 31, 2021 were as follows:


	March 31, 2022				December 31, 2021				Fair Value Level Hierarchy
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value
	(in millions)
8.00% senior secured notes	$	510.0	$	504.8	$	510.0	$	530.4	Level 3
Fixed-rate term loans	1,190.9		1,168.7		1,223.5		1,262.6		Level 3
Unsecured term loans	136.3		132.7		136.3		146.4		Level 3
2015-1 EETC Class A	300.6		294.0		300.6		311.1		Level 2
2015-1 EETC Class B	56.0		54.9		56.0		56.4		Level 2
2015-1 EETC Class C	75.2		73.3		75.2		74.0		Level 2

Total long-term debt	$	3,193.8	$	3,110.1	$	3,238.2	$	3,275.8

Cash and Cash Equivalents

Cash and cash equivalents at March 31, 2022 and December 31, 2021 are comprised of liquid money market funds and cash, and are categorized as Level 1 instruments. The Company maintains cash with various high-quality financial institutions.

Restricted Cash

Restricted cash is comprised of cash held in an account subject to account control agreements or otherwise pledged as collateral against the Company's letters of credit and is categorized as a Level 1 instrument. As of March 31, 2022, the Company had $85.0 million in standby letters of credit secured by $75.0 million of restricted cash, of which $27.0 million had been drawn upon for issued letters of credit. In addition, the Company had $20.4 million of restricted cash held in accounts subject to control agreements to be used for the payment of interest and fees on the 8.00% senior secured notes.

Short-term Investment Securities

Short-term investment securities at March 31, 2022 and December 31, 2021 are classified as available-for-sale and generally consist of U.S. Treasury and U.S. government agency securities with contractual maturities of 12 months or less. The Company's short-term investment securities are categorized as Level 1 instruments, as the Company uses quoted market prices in active markets when determining the fair value of these securities. For additional information, refer to Note 7, Short-term Investment Securities.

Derivative Liability

As a result of the settlement terms stipulated by the Merger Agreement, as of the Merger Agreement date, the convertible notes due 2026 no longer qualify for the derivative accounting scope exception provided under ASC 815. As such, the Company was required to bifurcate the fair value of the conversion option of the convertible notes due 2026 as a derivative liability as of the Merger Agreement date with subsequent changes in fair value recorded in earnings.

As of February 5, 2022, the Company recorded the fair value of the embedded derivative of $49.5 million as a derivative liability within deferred gains and other long-term liabilities and a debt discount within long-term debt and finance leases, less current maturities on its condensed consolidated balance sheets. The fair value of the derivative liability was estimated as the difference in value of the traded price of the convertible notes, including the conversion option and the value of the convertible notes in the absence of the conversion option (the debt component). The debt component was estimated using a discounted cash flow analysis with a yield calibrated to the traded price of the convertible notes. The fair value of the derivative liability has been determined to be Level 2 as observable inputs were used to determine the fair value of derivative liability. For additional information, refer to Note 12, Debt and Other Obligations.

Assets and liabilities measured at gross fair value on a recurring basis are summarized below:

The Company's Valuation Group, which reports to the Chief Financial Officer, is made up of individuals from the Company's Treasury and Corporate Accounting departments. The Valuation Group is responsible for the execution of the Company's valuation policies and procedures. The Valuation Group compares the results of the Company's internally developed valuation methods with counterparty reports at each balance sheet date, assesses the Company's valuation methods for accurateness and identifies any needs for modification.

12. Debt and Other Obligations

As of March 31, 2022, the Company had outstanding public and non-public debt instruments.

Revolving credit facility due in 2024

On March 30, 2020, the Company entered into a revolving credit facility for $110.0 million, with an option to increase the overall commitment amount up to $350 million with the consent of any participating lenders and subject to borrowing base availability. In the second quarter of 2020, the commitment was increased to $180.0 million and during the first quarter of 2021, the commitment was further increased to $240.0 million. As of March 31, 2022 and December 31, 2021, the Company had $240.0 million undrawn and available under this facility. Any amounts drawn on this facility are included in long-term debt and finance leases, less current maturities on the Company's condensed consolidated balance sheets. During the first quarter of 2021, the maturity date of the facility was extended for two additional years. The final maturity of the facility is March 30, 2024.

Convertible senior notes due 2025

On May 12, 2020, the Company completed the public offering of $175.0 million aggregate principal amount of 4.75% convertible senior notes due 2025 ("convertible notes due 2025"). As of March 31, 2022, the if-converted value exceeds the principal amount of the convertible notes by $22.4 million, using the average stock price for the three months ended March 31, 2022. Since the notes are currently convertible in accordance with the terms of the indenture governing such notes, the Company had $28.2 million recorded within current maturities of long-term debt and finance leases on its condensed consolidated balance sheets as of March 31, 2022 related to its convertible senior notes due 2025.

Noteholders may convert their notes at their option only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2020 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s common stock; and (4) at any time from, and including, February 18, 2025 until the close of business on the second scheduled trading day immediately before the maturity date. As of March 31, 2022, the notes may be converted by noteholders through June 30, 2022. No notes were converted during the three months ended March 31, 2022.

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. Based on the terms of the Merger Agreement executed on February 5, 2022 (the Merger Agreement date), upon conversion of any notes through the closing or termination of the merger, the conversion value, including the principal amount, will be paid all in shares of the Company's common stock. The initial conversion rate is 78.4314 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to an initial conversion price of approximately $12.75 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest.

Convertible senior notes due 2026

On April 30, 2021, the Company completed the public offering of $500.0 million aggregate principal amount of 1.00% convertible senior notes due 2026 ("convertible notes due 2026").

Noteholders may convert their notes at their option only in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Company’s common stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Company’s common stock; (4) if the Company calls such notes for redemption; and (5) at any time from, and including, February 17, 2026 until the close of business on the second scheduled trading day immediately before the maturity date. As of March 31, 2022, the notes did not qualify for conversion by noteholders through June 30, 2022.

Based on the terms of the indenture, the Company will have the right to elect to settle conversions in cash, shares of the Company’s common stock or a combination of cash and shares of common stock. However, upon conversion of any notes, the conversion value will be paid in cash up to at least the principal amount of the notes being converted. Based on the terms of the Merger Agreement with Frontier executed on February 5, 2022 (the Merger Agreement date), upon conversion of any notes through the closing or termination of the merger, the conversion value, including the principal amount, will be paid all in cash. The conversion value will be determined over an observation period consisting of 40 trading days, will be paid in cash up to at least the principal amount of the notes being converted. The initial conversion rate is 20.3791 shares of voting common stock per $1,000 principal amount of convertible notes (equivalent to an initial conversion price of approximately $49.07 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest.

The notes will be redeemable, in whole or in part (subject to certain limitations described below), at the Company’s option at any time, and from time to time, on or after May 15, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Company's common stock exceeds 130% of the conversion price for a specified period of time. However, the Company may not redeem less than all of the outstanding notes unless at least $150.0 million aggregate principal amount of notes are outstanding and not called for redemption as of the time the Company sends the related redemption notice.

As a result of the settlement terms stipulated by the Merger Agreement, as of the Merger Agreement date, the notes no longer qualify for the derivative accounting scope exception provided under ASC 815. As such, the Company was required to bifurcate the fair value of the conversion option of the convertible senior notes due 2026 as a derivative liability as of the Merger Agreement date with subsequent changes in fair value recorded in earnings.

As of February 5, 2022, the Company recorded the fair value of the embedded derivative of $49.5 million as a derivative liability within deferred gains and other long-term liabilities and a debt discount within long-term debt and finance leases, less current maturities on its condensed consolidated balance sheets. The debt discount will be amortized through interest expense, using the effective interest rate method, over the remaining life of the instrument. In addition, during the three months ended March 31, 2022, the Company recorded an adjustment to the derivative liability of $0.9 million within interest expense on its condensed consolidated statement of operations. Since the notes are currently not convertible in accordance with the terms of the indenture governing such notes, the Company had $453.0 million, net of the related unamortized debt discount of $47.0 million, recorded within long-term debt and finance leases, less current maturities on the Company's condensed consolidated balance sheets as of March 31, 2022 related to its convertible senior notes due 2026.

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

We evaluate our financial performance utilizing various accounting principles generally accepted in the United States of America (“GAAP”) and non-GAAP financial measures, including Adjusted CASM and Adjusted CASM ex-fuel. These non-GAAP financial measures are provided as supplemental information to the financial information presented in this quarterly report that is calculated and presented in accordance with GAAP and these non-GAAP financial measures are presented because management believes that they supplement or enhance management’s, analysts’ and investors’ overall understanding of our underlying financial performance and trends and facilitate comparisons among current, past and future periods.

Because the non-GAAP financial measures are not calculated in accordance with GAAP, they should not be considered superior to and are not intended to be considered in isolation or as a substitute for the related GAAP financial measures presented in this quarterly report and may not be the same as or comparable to similarly titled measures presented by other companies due to possible differences in the method of calculation and in the items being adjusted. We encourage investors to review our financial statements and other filings with the Securities and Exchange Commission in their entirety and not to rely on any single financial measure.

The information below provides an explanation of certain adjustments reflected in the non-GAAP financial measures and shows a reconciliation of non-GAAP financial measures reported in this quarterly report to the most directly comparable GAAP financial measures. Within the financial tables presented, certain columns and rows may not add due to the use of rounded numbers. Per unit amounts presented are calculated from the underlying amounts.

Operating expenses per available seat mile (“CASM”) is a common metric used in the airline industry to measure an airline’s cost structure and efficiency. We exclude loss on disposal of assets, special charges (credits) and accelerated depreciation to determine Adjusted CASM. We believe that also excluding aircraft fuel and related taxes ("Adjusted CASM ex-fuel") from certain measures is useful to investors because it provides an additional measure of management’s performance excluding the effects of a significant cost item over which management has limited influence and increases comparability with other airlines that also provide a similar metric. In prior periods, we excluded supplemental rent adjustments related to the modification of aircraft or engine leases from Adjusted CASM and Adjusted CASM ex-fuel. However, we no longer exclude supplemental rent adjustments from our non-GAAP measures. Therefore, 2021 non-GAAP measures have been revised to reflect this change and no longer exclude previously reported supplemental rent adjustments.

Overview

Spirit Airlines, headquartered in Miramar, Florida, offers affordable travel to value-conscious customers. Our all-Airbus fleet is one of the youngest and most fuel efficient in the United States. We serve destinations throughout the United States, Latin America and the Caribbean, and are dedicated to giving back and improving those communities. Our stock trades under the symbol "SAVE" on the New York Stock Exchange ("NYSE").

We focus on value-conscious travelers who pay for their own travel, and our business model is designed to deliver what our Guests want: low fares and a great experience. We compete based on total price. We allow our Guests to see all available options and their respective prices prior to purchasing a ticket, and this full transparency illustrates that our total price, including

options selected, is lower on average than other airlines. By offering Guests unbundled base fares, we give them the power to save by paying only for the À La Smarte® options they choose, such as checked and carry-on bags and advance seat assignments. We record revenue related to these options as non-fare passenger revenue, which is recorded within passenger revenues in our statement of operations.

We use low fares to address underserved markets, which helps us to increase passenger volume, load factors and non-ticket revenue. We also have high-density seating configurations on our fuel-efficient, all-Airbus fleet and a simplified onboard product designed to lower costs. High passenger volumes and load factors help us sell more ancillary products and services, which in turn allows us to reduce our fares even further.

We are committed to delivering the best value in the sky while providing an exceptional Guest experience. Our optimized mobile-friendly website makes booking easier. Our updated mobile app allows Guests to search for the lowest fares, book and check in while on the go, and our airport kiosks and self-bag tagging help our Guests move through the airport more quickly.

Executive Summary

As a result of the COVID-19 pandemic, we experienced sharp declines in passenger demand and bookings beginning in March 2020 that lasted throughout 2020, and to a lesser extent throughout 2021. During the first quarter of 2022, we have seen continued improvement in our passenger demand and bookings, which we expect to continue throughout the remainder of 2022. However, during the first quarter of 2022 and ongoing, the airline industry has experienced a number of adverse weather events, which combined with increases in Air Traffic Control (ATC) programs and restrictions, have led to a significant number

of flight delays and cancellations. We will continue to monitor the impact of these operational challenges and to adjust our mitigation and operational strategies accordingly. The situation continues to be fluid and demand and our resulting capacity may be different than what we currently expect.

Load factor for the first quarter of 2022 was 77.2% as compared to 72.1% for the same period in the prior year. We experienced an increase in capacity of 46.9%, period over period, as air travel demand continued to increase compared to the same period in the prior year. As the COVID-19 pandemic continues to evolve, our financial and operational outlook remains subject to change.

Announcement of Merger

On February 5, 2022, Spirit Airlines entered into a Merger Agreement with Frontier Group Holdings, Inc., a Delaware corporation, and Top Gun Acquisition Corp., a Delaware corporation and a direct, wholly owned subsidiary of Frontier, pursuant to which and subject to the terms and conditions therein, Merger Sub will merge with and into Spirit Airlines, with Spirit Airlines continuing as the surviving entity. As a result of the Merger, each existing share of Spirit Airlines’ common stock will be converted into the right to receive (i) $2.13 in cash, without interest and (ii) 1.9126 shares of Frontier Common Stock, par value $0.001 per share. Upon consummation of the Merger, existing shareholders of Spirit Airlines will own approximately 48.5% of the outstanding shares of Frontier on a fully diluted basis.

Completion of the Merger is subject to the satisfaction or waiver of certain closing conditions, including, among other things, (1) approval of the Merger Agreement by Spirit Airlines’ stockholders, (2) receipt of applicable regulatory approvals, including approvals from the FCC, FAA and the DOT and the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other required regulatory approvals; (3) the absence of any law or order prohibiting the consummation of the transactions; (4) the effectiveness of the registration statement to be filed by Frontier and Spirit Airlines with the SEC pursuant to the Merger Agreement; (5) the authorization and approval for listing on NASDAQ of the shares of Frontier Common Stock to be issued to holders of Spirit Airlines’ common stock in the Merger; and (6) the absence of any material adverse effect (as defined in the Merger Agreement) on either Spirit Airlines or Frontier.

On April 5, 2022, we announced that we received an unsolicited proposal from JetBlue to acquire all of the outstanding shares of Spirit Airlines’s common stock in an all-cash transaction for $33.00 per share. After consulting with financial and legal advisors, our Board of Directors determined that JetBlue’s proposal could reasonably be likely to lead to a "Superior Proposal" as defined in our merger agreement with Frontier and evaluated the proposal in accordance with the terms of the merger agreement.

On May 2, 2022, we announced that our Board of Directors, in consultation with outside financial and legal advisors, unanimously determined that the unsolicited proposal received from JetBlue does not constitute a "Superior Proposal" due to an unacceptable level of deal completion risk. We will continue to advance toward completing the transaction with Frontier, which is expected to close in the second half of 2022. The transaction is subject to customary closing conditions, including completion of the ongoing regulatory review process and approval of our stockholders.

Summary of Results

For the first quarter of 2022, we had a negative operating margin of 21.9%, an increase of 0.3 percentage points compared to a negative operating margin of 22.2% in the prior year period. We generated a pre-tax loss of $244.0 million and a net loss of $194.7 million on operating revenues of $967.3 million. For the first quarter of 2021, we generated a pre-tax loss of $138.2 million and a net loss of $112.3 million on operating revenues of $461.3 million.

Our Adjusted CASM ex-fuel for the first quarter of 2022 was 6.68 cents compared to 7.46 cents in the same period in the prior year. The decrease on a per-ASM basis was primarily due to improved air travel demand, as compared to the prior year period, which drove a significant increase of 46.9% in ASMs, period over period. This increase in ASMs drove a decrease in operating expenses on a per-ASM basis with the greatest impact noted on primarily fixed costs such as salaries, wages, and benefits expense, depreciation and amortization expense, landing fees and other rents expense and aircraft rent expense.

As of March 31, 2022, we had 176 Airbus A320-family aircraft in our fleet comprised of 31 A319s, 64 A320s, 30 A321s, and 51 A320neos. With the scheduled delivery of 21 aircraft during the remainder of 2022, we expect to end 2022 with 197 aircraft in our fleet.

Comparison of three months ended March 31, 2022 to three months ended March 31, 2021

Operating Revenues

Operating revenues increased $506.0 million, or 109.7%, to $967.3 million for the first quarter of 2022, as compared to the first quarter of 2021, primarily due to an increase in traffic of 57.5%, an increase in average yield of 33.1% and an increase in load factor of 5.1 pts, year over year, driven by increased air travel demand as compared to prior year period.

Total revenue per passenger flight segment increased 34.9%, year over year. The increase in total revenue per passenger flight segment was primarily driven by a 33.1% increase in average yield, period over period. Fare revenue per passenger flight segment increased 54.5% and non-ticket revenue per passenger flight segment increased 23.1%. The increase in non-ticket revenue per passenger flight segment was primarily attributable to increases in change fee revenue, passenger usage fee, boost-it and bundle-it revenue, seat revenue and bag revenue per passenger flight segment, as compared to the prior year.

Operating Expenses

Operating expenses increased $615.0 million, or 109.1%, to $1,178.8 million for the first quarter of 2022 compared to $563.8 million for the first quarter of 2021, primarily due to an increase in operations as reflected by a 57.5% increase in traffic and 46.9% increase in capacity. We also had a 66.7% increase in average economic fuel cost per gallon and a 55.1% increase in fuel gallons consumed, both of which contributed to a $225.7 million increase in aircraft fuel expense, period over period. In addition, we had $15.6 million in special charges in the first quarter of 2022 compared to $176.9 million in special credits during the first quarter of 2021. For additional information, refer to "Notes to Condensed Consolidated Financial Statements—5. Special Charges (Credits)."

Aircraft fuel expense includes into-plane fuel expense (defined below) and realized and unrealized gains and losses associated with our fuel derivative contracts, if any. Into-plane fuel expense is defined as the price that we generally pay at the airport, including taxes and fees. Into-plane fuel prices are affected by the global oil market, refining costs, taxes and fees, which can vary by region in the United States and other countries where we operate. Into-plane fuel expense approximates cash paid to the supplier and does not reflect the effect of any fuel derivatives. We had no activity related to fuel derivative instruments during the three months ended March 31, 2022 and 2021.

Aircraft fuel expense increased by $225.7 million, or 157.9%, from $142.9 million in the first quarter of 2021 to $368.6 million in the first quarter of 2022. This higher fuel expense, period over period, was due to a 66.7% increase in average economic fuel cost per gallon and a 55.1% increase in fuel gallons consumed.

The elements of the changes in aircraft fuel expense are illustrated in the following table:


	Three Months Ended March 31,
	2022		2021
	(in thousands, except per-gallon amounts)				Percent Change
Fuel gallons consumed	124,916		80,546		55.1	%
Into-plane fuel cost per gallon	$	2.95	$	1.77	66.7	%



Aircraft fuel expense (per condensed consolidated statements of operations)	$	368,585	$	142,930	157.9	%

Gulf Coast Jet indexed fuel is the basis for a substantial majority of our fuel consumption and is impacted by both the price of crude oil as well as increases or decreases in refining margins associated with the conversion of crude oil to jet fuel. The into-plane fuel cost per gallon increase of 66.7% was primarily a result of an increase in jet fuel prices.

We measure our operating cost performance on a per-ASM basis, since one ASM is the unit of production of an airline’s capacity. The following table presents our cost per-ASM, or unit cost, for the three months ended March 31, 2022 and 2021, followed by explanations of the material changes on a dollar basis and/or unit cost basis:

Our Adjusted CASM ex-fuel for the first quarter of 2022 was 6.68 cents as compared to 7.46 cents for the first quarter of 2021. Improved air travel demand, as compared to the prior year period, drove a significant increase in ASMs of 46.9%, period over period. This increase in ASMs drove a decrease in operating expenses on a per-ASM basis with the greatest impact noted on primarily fixed costs such as salaries, wages and benefits expense, landing fees and other rents expense and depreciation and amortization expense.

Salaries, wages and benefits for the first quarter of 2022 increased $60.2 million, or 24.5%, as compared to the first quarter of 2021. This increase was primarily driven by higher salaries, crew overtime and per diem pay and 401(k) expense, period over period. The increase in salaries, crew overtime and per diem was mainly driven by an 18.6% increase in our pilot and flight attendant workforce, period over period, as well as due to an increase in operations as compared to the prior year period. The increase in 401(k) expense was mainly driven by higher average pay rates and 401(k) employer contribution rates to our pilots as compared to the prior year period.

Depreciation and amortization for the first quarter of 2022 increased by $1.9 million, or 2.5%, as compared to the prior year period. The increase in depreciation expense on a dollar basis was primarily driven by an increase in computer hardware and spare rotables. In addition, for the three months ended March 31, 2022, we had an increase in depreciation and amortization expense due the cash purchase of two spare engines and the purchase of two previously leased spare engines since the first quarter of 2021.

We account for heavy maintenance under the deferral method. Under the deferral method, the cost of heavy maintenance is capitalized and amortized as a component of depreciation and amortization expense in the statement of operations until the

earlier of the next heavy maintenance event or the end of the lease term. The amortization of heavy maintenance costs was $23.5 million and $23.9 million for the first quarters of 2022 and 2021, respectively. The amortization of heavy maintenance costs is driven by the timing and number of maintenance events. As our fleet continues to grow and age, we expect that the amount of deferred heavy maintenance events will increase and will result in an increase in the amortization of those costs. If heavy maintenance events were amortized within maintenance, materials and repairs expense in the condensed consolidated statements of operations, our maintenance, materials and repairs expense would have been $69.0 million and $53.8 million for the first quarter of 2022 and 2021, respectively.

Landing fees and other rents for the first quarter of 2022 increased $10.8 million, or 15.0%, as compared to the first quarter of 2021. On a dollar basis, landing fees and other rents expense primarily increased as a result of an increase in facility rent, landing fees, overfly fees, gate charges and station baggage rent driven by increased operations. A portion of our landing fees and other rents are variable in nature and vary based on factors such as the number of departures. As compared to the prior year period, departures increased by 52.4% and passenger flight segments increased by 55.4%. In addition, as compared to the prior year period, we had an increase in facility rent driven by higher rent rates, period over period. These increases were partially offset by an increase in signatory adjustment credits as compared to the prior year period.

Aircraft rent expense for the first quarter of 2022 increased by $11.3 million, or 20.6%, as compared to the first quarter of 2021. This increase in aircraft rent expense was primarily due to an increase in the number of aircraft financed under operating leases throughout the current period, as compared to the prior year period. Since the first quarter of 2021, we have acquired 16 new aircraft financed under operating leases. The increases generated by the new leased aircraft were partially offset by the purchase of four aircraft off lease completed during 2021.

Maintenance, materials and repairs expense for the first quarter of 2022 increased by $15.6 million, or 52.2%, as compared to the first quarter of 2021. On a per dollar basis and per-ASM basis, the increase in maintenance, materials and repairs expense was mainly due to a higher volume of aircraft and rotable maintenance events as a result of a 42.1% increase in average daily aircraft utilization in the current period as compared to the prior year period.

Distribution costs increased by $11.7 million, or 49.5%, in the first quarter of 2022 as compared to the first quarter of 2021. The increase on a dollar basis was primarily due to increased sales volume, resulting from increased air travel demand, which impacts our variable distribution costs such as credit card fees. On a per-ASM basis, distribution costs remained stable, period over period.

Loss on disposal of assets for the three months ended March 31, 2022 primarily consisted of $6.6 million related to the impairment of one spare engine which was damaged beyond economic repair and $4.3 million related to the loss on three aircraft sale leaseback transactions completed during the first quarter of 2022. Loss on disposal for the three months ended March 31, 2021 consisted of $1.1 million related to the sale of auxiliary power units ("APUs") and disposal of excess and obsolete inventory.

Special charges for the three months ended March 31, 2022 consisted of $11.1 million in legal, advisory and other fees related to the Merger Agreement and $4.5 million related to our retention bonus program. Special credits for the three months ended March 31, 2021 consisted of $156.5 million of deferred salaries, wages and benefits recognized in connection with the grant component of the PSP2 with Treasury. In addition, we recorded $21.3 million related to the CARES Act Employee Retention credit. These special credits were partially offset by $0.8 million in special charges recorded in connection with the rehire of Team Members previously terminated under our involuntary employee separation program which were rehired in compliance with the restrictions mandated by our participation in the PSP2. For additional information, refer to "Notes to Condensed Consolidated Financial Statements—5. Special Charges (Credits)."

Other operating expenses for the first quarter of 2022 increased by $74.9 million, or 77.8%, as compared to the first quarter of 2021. The increase in other operating expenses on a dollar basis was primarily due to an increase in overall operations and an increase in ground handling, travel and lodging and passenger reaccomodation expense, period over period. As compared to the prior year period, departures increased by 52.4% and passenger flight segments increased by 55.4%, which drove these increases in variable other operating expenses. In addition, we had higher passenger reaccomodation expense, period over period, related to a number of adverse weather events and increases in ATC programs and restrictions, which led to a significant number of flight delays and cancellations during the first quarter of 2022. On a per-ASM basis, this higher passenger reaccommodation expense and travel and lodging expense were the main drivers of the increase in other operating expense, as compared to the prior year period.

Other (Income) Expense

Our interest expense and corresponding capitalized interest for the three months ended March 31, 2022 primarily represent interest related to the financing of purchased aircraft as well as the interest and accretion related to our 8.00% senior secured notes, the discount amortization related to our convertible notes due in 2026 and the interest related to our convertible notes. Our interest expense and corresponding capitalized interest for the three months ended March 31, 2021, primarily represents interest related to the financing of purchased aircraft as well as the interest related to our convertible notes and 8.00% senior secured notes. As of March 31, 2022 and 2021, we had 73 and 72 aircraft financed through fixed-rate long-term debt, respectively.

Our interest income for the three months ended March 31, 2022 represents interest income earned on our cash, cash equivalents and short-term investments. Our interest income for the three months ended March 31, 2021 represents interest income earned on our income tax receivable, cash, cash equivalents and short-term investments.

Income Taxes

Our effective tax rate for the first quarter of 2022 was 20.2% compared to 18.7% for the first quarter of 2021. The increase in the tax rate, as compared to the prior year period, is primarily due to a higher annualized effective tax rate in 2022. While we expect our tax rate to be a fairly consistent in the near term, it will tend to vary depending on recurring items such as the amount of income we earn in each state and the state tax applicable to such income. Discrete items particular to a given year may also affect our effective tax rates.

Liquidity and Capital Resources

Our primary sources of liquidity generally include cash on hand, cash provided by operations and capital from debt and equity financing. Primary uses of liquidity are for working capital needs, capital expenditures, aircraft and engine pre-delivery deposit payments ("PDPs") and debt and lease obligations. We expect to meet our cash needs for the next twelve months with cash and cash equivalents, financing arrangements and cash flows from operations. As of March 31, 2022, we had $1,593.9 million of liquidity comprised of unrestricted cash and cash equivalents, short-term investment securities and funds available under our revolving credit facility due in 2024.

As of March 31, 2022, we had $28.2 million recorded within current maturities of long-term debt and finance leases on our condensed consolidated balance sheets related to our 4.75% convertible notes due 2025. As of March 31, 2022, the 4.75% convertible notes due 2025 may be converted by noteholders through June 30, 2022. No notes were converted during three months ended March 31, 2022. Refer to "Notes to Condensed Consolidated Financial Statements—12. Debt and Other Obligations," for additional information on the 4.75% convertible notes due 2025.

As of March 31, 2022, we had $453.0 million, net of the related unamortized debt discount of $47.0 million, recorded within long-term debt and finance leases, less current maturities on our condensed consolidated balance sheets related to our 1.00% convertible notes due 2026. As of March 31, 2022, the 1.00% convertible notes due 2026 did not qualify for conversion by noteholders through June 30, 2022. Refer to "Notes to Condensed Consolidated Financial Statements —12. Debt and Other Obligations" for additional information on the 1.00% convertible notes due 2026.

Currently, one of our largest capital expenditure needs is funding the acquisition costs of our aircraft. Aircraft may be acquired through debt financing, cash purchases, direct leases or sale leaseback transactions. During the three months ended March 31, 2022, we took delivery of three aircraft under sale leaseback transactions and one spare engine purchased with cash. During the three months ended March 31, 2022, we made $74.3 million in debt payments (principal, interest and fees) on our outstanding aircraft debt obligations.

Under our purchase agreements for aircraft and engines, we are required to pay PDPs relating to future deliveries at various times prior to each delivery date. During the three months ended March 31, 2022, we paid $5.9 million in PDPs, net of refunds, and $4.2 million of capitalized interest for future deliveries of aircraft and spare engines. As of March 31, 2022, we had $489.2 million of pre-delivery deposits on flight equipment, including capitalized interest, on our condensed consolidated balance sheets.

As of March 31, 2022, we have secured financing for 40 aircraft to be leased directly from third-party lessors and 14 aircraft which will be financed through sale leaseback transactions, with deliveries expected through 2024. We do not have

financing commitments in place for the remaining 103 Airbus firm aircraft orders, scheduled for delivery through 2027. However, we have a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement signed in the fourth quarter of 2019. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing. Future aircraft deliveries may be paid in cash, leased or otherwise financed based on market conditions, our prevailing level of liquidity, and capital market availability.

Net Cash Flows Provided By Operating Activities. Operating activities in the three months ended March 31, 2022 provided $19.5 million in cash compared to $186.6 million provided in the three months ended March 31, 2021. Cash provided by operating activities in the three months ended March 31, 2022 is primarily related to cash provided from an increase in air traffic liability, an increase in other liabilities as well as higher non-cash expense of depreciation and amortization. These increases were partially offset by the net loss in the period as well as the increase in accounts receivable, net, the increase in deposits and other assets and the deferred income tax benefit in the period.

Net Cash Flows Used In Investing Activities. During the three months ended March 31, 2022, investing activities used $57.6 million, compared to $97.5 million used in the prior year period. The decrease was mainly driven by a decrease in in PDPs paid, net of refunds, as well as a decrease in purchases of property and equipment, year over year.

Net Cash Flows Used By Financing Activities. During the three months ended March 31, 2022, financing activities used $47.5 million in cash compared to $111.8 million used in the three months ended March 31, 2021. During the three months ended March 31, 2022, we paid $44.3 million in debt principal payment obligations.

Commitments and Contractual Obligations

Our contractual purchase commitments consist primarily of aircraft and engine acquisitions through manufacturers and aircraft leasing companies. As of March 31, 2022, our aircraft orders consisted of 117 A320 family aircraft with Airbus, including A319neos, A320neos and A321neos, with deliveries expected through 2027. Out of these 117 aircraft, we have 14 aircraft scheduled for delivery in the remainder of 2022 and 17 aircraft scheduled for delivery in 2023.

During the third quarter of 2021, we entered into an Engine Purchase Support Agreement which requires us to purchase a certain number of spare engines in order to maintain a contractual ratio of spare engines to aircraft in the fleet. As of March 31, 2022, we are committed to purchase 15 PW1100G-JM spare engines, with deliveries through 2027. During the third quarter of 2019, the United States announced its decision to levy tariffs on certain imports from the European Union, including commercial aircraft and related parts. These tariffs would include aircraft and other parts that we are already contractually obligated to purchase including those reflected above. In June 2021, the United States Trade Representative announced that the United States and European Union had agreed to suspend reciprocal tariffs on large civilian aircraft for five years, pending discussions to resolve their trade dispute.

In addition, as of March 31, 2022, we had secured 40 direct leases for aircraft with third-party lessors, with deliveries in the remainder of 2022 through 2024. As of March 31, 2022, we had secured financing for 14 aircraft, scheduled for delivery from Airbus through the remainder of 2022, which will be financed through sale leaseback transactions. The contractual purchase amounts for these aircraft from Airbus are included within the flight equipment purchase obligations in the table below. Aircraft rent commitments for future aircraft deliveries to be financed under direct leases from third-party lessors and sale leaseback transactions are expected to be approximately $30.2 million for the remainder of 2022, $124.9 million in 2023, $202.3 million in 2024, $231.2 million in 2025, $231.2 million in 2026, and $1,954.2 million in 2027 and beyond. As of March 31, 2022, we do not have financing commitments in place for the remaining 103 Airbus aircraft on firm order through 2027. However, we have a financing letter of agreement with Airbus which provides backstop financing for a majority of the aircraft included in the A320 NEO Family Purchase Agreement signed in the fourth quarter of 2019. The agreement provides a standby credit facility in the form of senior secured mortgage debt financing.

We have significant obligations for aircraft and spare engines as 70 of our 176 aircraft and 12 of our 33 spare engines are financed under operating leases. These leases expire between 2022 and 2040. Aircraft rent payments were $64.9 million and $59.0 million and for the three months ended March 31, 2022 and March 31, 2021, respectively.

Our fixed-rate operating leases with terms greater than 12 months are included within operating lease right-of-use assets with the corresponding liabilities included within current maturities of operating leases and operating leases, less current maturities on our condensed consolidated balance sheets. Leases with a term of 12 months or less and variable-rate leases are not recorded on our condensed consolidated balance sheets. Please see "Notes to Condensed Consolidated Financial Statements—9. Leases" for further discussion on our leases.

We have contractual obligations and commitments primarily with regard to future purchases of aircraft and engines, payments of debt, and lease arrangements. The following table discloses aggregate information about our contractual obligations as of March 31, 2022 and the periods in which payments are due (in millions):

During the fourth quarter of 2019, we purchased an 8.5-acre parcel of land for $41.0 million and entered into a 99-year lease agreement for the lease of a 2.6-acre parcel of land, in Dania Beach, Florida, where we are building a new headquarters campus. During January 2022, we began building our new headquarters campus with an expected completion during the fourth quarter 2023. Operating lease commitments related to this lease are included in the table above under the caption "Finance and operating lease obligations." For more detailed information, please refer to “Notes to Condensed Consolidated Financial Statements— 9. Leases." Commitments related to the construction of the headquarters campus are included in the table above under the caption "Other."

Off-Balance Sheet Arrangements

As of March 31, 2022, we had lines of credit related to corporate credit cards of $40.1 million, from which we had drawn $1.0 million.

As of March 31, 2022, we had lines of credit with counterparties for both physical fuel delivery and derivatives in the amount of $41.5 million. As of March 31, 2022, we had drawn $15.3 million on these lines of credit for physical fuel delivery. We are required to post collateral for any excess above the lines of credit if the derivatives are in a net liability position and make periodic payments in order to maintain an adequate undrawn portion for physical fuel delivery. As of March 31, 2022, we did not hold any derivatives.

As of March 31, 2022, we had $7.0 million in uncollateralized surety bonds and $85.0 million in standby letters of credit, collateralized by $75.0 million of restricted cash, representing an off-balance sheet commitment, of which $27.0 million had been drawn upon for issued letters of credit.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk-Sensitive Instruments and Positions

We are subject to certain market risks, including commodity prices (specifically aircraft fuel) and interest rates. We purchase the majority of our jet fuel at prevailing market prices and seek to manage market risk through execution of our hedging strategy and other means. We have market-sensitive instruments in the form of fixed-rate debt instruments, short-term investment securities and, from time to time, financial derivative instruments used to hedge our exposure to jet fuel price increases and interest rate increases. We do not purchase or hold any derivative financial instruments for trading purposes. The adverse effects of changes in these markets could pose a potential loss as discussed below. The sensitivity analysis provided below 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. Aircraft fuel expense for the three months ended March 31, 2022 represented approximately 31.3% of our operating expenses. Volatility in aircraft fuel prices or a shortage of supply could have a material adverse effect on our operations and operating results. We source a significant portion of our fuel from refining resources located in the southeast United States, particularly facilities adjacent to the Gulf of Mexico. Gulf Coast fuel is subject to volatility and supply disruptions, particularly during hurricane season when refinery shutdowns have occurred, or when the threat of weather-related disruptions has caused Gulf Coast fuel prices to spike above other regional sources. Both jet fuel swaps and jet fuel options are used at times to protect the refining price risk between the price of crude oil and the price of refined jet fuel, and to manage the risk of increasing fuel prices. Gulf Coast Jet indexed fuel is the basis for a substantial majority of our fuel consumption. Based on our annual fuel consumption over the last 12 months, a hypothetical 10% increase in the average price per gallon of aircraft fuel would have increased into-plane aircraft fuel expense by approximately $114 million. As of March 31, 2022, we did not have any outstanding jet fuel derivatives, and we have not engaged in fuel derivative activity since 2015.

Interest Rates. We have market risk associated with our short-term investment securities, which had a fair market value of $106.0 million as of March 31, 2022.

Fixed-Rate Debt. As of March 31, 2022, we had $2,019.3 million outstanding in fixed-rate debt related to 43 Airbus A320 aircraft and 30 Airbus A321 aircraft which had a fair value of $1,968.5 million. In addition, as of March 31, 2022, we had $510.0 million and $136.3 million outstanding in fixed-rate debt related to our 8.00% senior secured notes and our unsecured term loans, respectively, which had fair values of $504.8 million and $132.7 million. As of March 31, 2022, we also had $528.2 million outstanding in convertible debt which had a fair value of $504.1 million.

Variable-Rate Debt. As of March 31, 2022, we did not have any outstanding variable-rate long term debt.

ITEM 4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and our Chief 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, means 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 our management, including its chief executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on the evaluation of our disclosure controls and procedures as of March 31, 2022, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, 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 Rule 13a-15(f) under the Exchange Act), during the quarter ended March 31, 2022 that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.

We are subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. We believe the ultimate outcome of such lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on our financial position, liquidity or results of operations.

Following an audit by the IRS related to the collection of federal excise taxes on optional passenger seat selection charges covering the period of the second quarter 2018 through the fourth quarter 2020, on March 31, 2022, we were assessed $34.9 million. We believe the assessment is without merit and intend to challenge the assessment.

Investors are urged to review such risk factors carefully.
