NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except per share and share amounts)

(Unaudited)

1.    BASIS OF PRESENTATION

Sun Country Airlines Holdings, Inc. (together with its consolidated subsidiaries, "Sun Country" or the "Company") is the parent company of Sun Country, Inc., which is a certificated air carrier providing scheduled passenger service, air cargo service, charter air transportation and related services.

The Company has prepared the unaudited Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (“GAAP”) and has included the accounts of Sun Country Airlines Holdings, Inc. and its subsidiaries. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Form 10-Q. Therefore, the accompanying Condensed Consolidated Financial Statements of Sun Country Airlines Holdings, Inc. should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the SEC ("2022 10-K"). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited Condensed Consolidated Financial Statements for the interim periods presented. All material intercompany balances and transactions have been eliminated in consolidation.

The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

The Company completed its public float calculation for SEC reporting purposes as of June 30, 2023, as required. The Company will be a large accelerated filer as of December 31, 2023.

Due to impacts from seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, uncertainties in pilot staffing, the impact of macroeconomic conditions including inflationary pressures, and other factors, operating results for the six months ended June 30, 2023 are not necessarily indicative of operating results for future quarters or for the year ending December 31, 2023.

2.    REVENUE

Sun Country is a certificated air carrier generating Operating Revenues from Scheduled service, Charter service, Ancillary, Cargo and Other revenue. Scheduled service revenue mainly consists of base fares. Charter service revenue is primarily generated through service provided to the U.S. Department of Defense, collegiate and professional sports teams, and casinos. Ancillary revenues consist of revenue earned from air travel-related services, such as: baggage fees, seat selection fees, passenger interface fees and on-board sales. Cargo consists of revenue earned from flying cargo aircraft for Amazon.com Services, Inc. (together with its affiliates, “Amazon”) under the Air Transportation Services Agreement (the “ATSA”). Other revenue consists primarily of revenue from services in connection with Sun Country Vacations products and rental revenue related to certain transactions where the Company acts as a lessor.

Contract Assets and Liabilities are as follows:

	June 30, 2023		December 31, 2022
Contract Assets
Costs to fulfill contract with Amazon	$	1,855	$	2,195
Total Contract Assets	$	1,855	$	2,195
Contract Liabilities
Air Traffic Liabilities	$	130,264	$	157,995
Loyalty Program Liabilities	13,656		15,437
Amazon Deferred Up-front Payment	2,764		3,271
Total Contract Liabilities	$	146,684	$	176,703

The balance in the Air Traffic Liabilities fluctuates with seasonal travel patterns. Most tickets can be purchased no more than twelve months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the six months ended June 30, 2023, $146,904 of revenue was recognized in Passenger revenue that was included in the Air Traffic Liabilities as of December 31, 2022.

Loyalty Program

The Sun Country Rewards program provides loyalty awards to program members based on accumulated loyalty points. The Company records a liability for loyalty points earned by passengers under the Sun Country Rewards program using two methods: 1) a liability for points that are earned by passengers on purchases of the Company’s services is established by deferring revenue based on the redemption value, net of estimated loyalty points that will expire unused, or breakage; and 2) a liability for points attributed to loyalty points issued to the Company’s Visa card holders is established by deferring a portion of payments received from the Company’s co-branded agreement. The balance of the Loyalty Program Liabilities fluctuates based on seasonal patterns, which impacts the volume of loyalty points awarded through travel or issued to co-branded credit card and other partners (deferral of revenue) and loyalty points redeemed (recognition of revenue). Due to these reasons, the timing of loyalty point redemptions can vary significantly.

Changes in the Loyalty Program Liabilities are as follows:

	2023		2022
Balance – January 1	$	15,437	$	19,718
Loyalty Points Earned	4,262		3,471
Loyalty Points Redeemed (1)	(6,043)		(6,585)
Balance – June 30	$	13,656	$	16,604

______________________

(1) Loyalty points are combined in one homogenous pool, which includes both air and non-air travel awards, and are not separately identifiable. As such, the revenue recognized is comprised of points that were part of the Loyalty Program Liabilities balance at the beginning of the period, as well as points that were earned during the period.

During the six months ended June 30, 2023, the Company acquired five 737-900ERs that are currently on lease to an unaffiliated airline ("Aircraft Held for Operating Lease"). The five Aircraft Held for Operating Lease were financed through a term loan arrangement. See Note 5 of these Condensed Consolidated Financial Statements for more information on this transaction. Additionally, during the six months ended June 30, 2023, the Company acquired an incremental aircraft and executed a lease amendment to purchase one aircraft at the end of its lease term. An additional aircraft purchase amendment was executed subsequent to June 30, 2023. The lease amendments modified the classification of these leases from operating leases to finance leases and have expiration dates in fiscal year 2024. Of the 35 Owned aircraft

and Aircraft Held for Operating Lease as of June 30, 2023, 31 were financed and four aircraft were unencumbered.

During the six months ended June 30, 2022, the Company executed lease amendments to purchase two aircraft at the end of the lease term, which modified the lease classification from operating leases to finance leases with expiration dates in fiscal year 2026 and retired one aircraft. Further, the Company purchased an aircraft previously classified as a finance lease using proceeds of the from the issuance of Class A and Class B pass-through trust certificates (the "2022-1 EETC"). The Company also acquired six incremental 737-800 aircraft, five of which were financed using proceeds from the 2022-1 EETC and another through a finance lease arrangement that is set to expire in fiscal year 2030.

Depreciation, amortization, and rent expense on aircraft are as follows:

		Three Months Ended June 30,				Six Months Ended June 30,
Aircraft Status	Expense Type	2023		2022		2023		2022

(1) Aircraft Rent expense includes credits for the amortization of over-market liabilities established at the Acquisition Date.

5. ASSET ACQUISITIONS

During the six months ended June 30, 2023, the Company acquired five Aircraft Held for Operating Lease. The table below reflects the cumulative balances of the five aircraft as of the acquisition dates:

Asset	Balance Sheet Classification
Aircraft Held for Operating Lease	Aircraft and Flight Equipment Held for Operating Lease	$	114,628
Maintenance Rights Asset	Aircraft and Flight Equipment Held for Operating Lease	39,533
Over-Market Asset	Other Intangible Assets, net	3,741
Total		$	157,902

The purchase price was assigned to the assets based upon their relative fair values as of the acquisition date. The Company estimated the fair value of the Aircraft Held for Operating Lease principally based on market appraisals. The appraisals were based on an analysis of the economic conditions impacting both the airline industry and broader economy, the current fuel price environment, aircraft order data, passenger traffic levels, and qualitative and quantitative characteristics impacting the value of the acquired aircraft.

The fair value of the Maintenance Rights Asset was determined using a discounted cash flow method based on aircraft utilization levels at the time of the acquisition and the applicable rates as specified within the lease agreements.

The fair value of the Over-Market Asset was determined using a discounted cash flow model that involves the comparison of contractual lease cash flows to the estimated at-market lease payments for an aircraft of the same type and age.

(Unaudited)

The purchase of the Aircraft Held for Operating Lease was financed using the proceeds from a term loan credit facility with a face amount of $119,200 and the Company's cash. For more information on the term loan credit facility, see Note 6 of these Condensed Consolidated Financial Statements.

Aircraft Held for Operating Lease

The Company obtained outright ownership of the Aircraft Held for Operating Lease upon purchase and assumed the position of lessor until the end of the lease terms. The Company is entitled to fixed payments over the remaining lease term for each aircraft, which expire at various dates between the fourth quarter of 2024 and the fourth quarter of 2025. On each lease expiry date, the Aircraft Held for Operating Lease will be redelivered to Sun Country and are expected to be inducted into the Company’s fleet. The rental revenue associated with the Aircraft Held for Operating Lease is recognized as it is earned and is included in Other revenue. The Company has recognized $5,871 of rental revenue during the six months ended June 30, 2023.

Maintenance Rights Asset

Upon purchase of the Aircraft Held for Operating Lease, the Company recognized a Maintenance Rights Asset which represents the Company’s contractual right to receive the aircraft in a specified maintenance condition at the end of the lease. The acquired leases contain an end of lease compensation clause whereby the lessee is required to remit a cash payment to true-up the aircraft’s maintenance condition to full-life or perform the maintenance tasks needed to physically restore the airframe and engines to such a condition. The asset represents the difference between the Aircraft Held for Operating Lease’s physical maintenance condition as of the purchase date and the contractual return condition at the end of the lease term. The Maintenance Rights Asset is not depreciated over the lease term, nor will it accrete as additional life is consumed on the aircraft.

Over-Market Asset

Upon purchase of the Aircraft Held for Operating Lease, the Company recognized an intangible asset representing lease terms which are favorable to the lessor (unfavorable to the lessee), as compared with market terms of similar leases. The asset will be amortized over the remaining lease terms for the respective aircraft, which range from 1.4-2.4 years as of June 30, 2023. The amortization will be recognized as contra-revenue, offsetting the rental revenue associated with the Aircraft Held for Operating Lease included in Other revenue.

6.    DEBT

Credit Facilities

On February 10, 2021, the Company executed a five-year credit agreement (the “Credit Agreement”) with a group of lenders. The Credit Agreement includes a $25,000 Revolving Credit Facility (the "Revolving Credit Facility") and a $90,000 Delayed Draw Term Loan Facility (“DDTL”), which are collectively referred to as the “Credit Facilities.” The proceeds from the Revolving Credit Facility can be used for general corporate purposes, whereas the proceeds from the DDTL were to be used solely to finance the acquisition of aircraft or engines to be registered in the United States. The Credit Agreement includes financial covenants that require a minimum trailing 12-month EBITDAR ($87,700 as of March 31, 2022 and beyond) and minimum liquidity of $30,000 at the close of any business day. The Company was in compliance with these covenants as of June 30, 2023.

(Unaudited)

During 2021, the Company drew $80,500 on the DDTL to purchase six aircraft, which were previously under operating leases. During 2022, the Company repaid the outstanding balance of the DDTL in full using proceeds received from the 2022-1 EETC, which terminated the DDTL. As a result, no amounts under the DDTL were available to the Company as of June 30, 2023. The Company recorded a $1,557 loss on extinguishment of debt in 2022 in connection with the repayment of the DDTL, which represents the write-off of the unamortized deferred financing costs. As of June 30, 2023, the Company had $24,650 of financing available through the Revolving Credit Facility, as $350 had been pledged to support a letter of credit.

Long-term Debt

Term Loan Credit Facility

During the six months ended June 30, 2023, the Company executed a term loan credit facility with a face amount of $119,200 for the purpose of financing the five Aircraft Held for Operating Lease. The loan is to be repaid monthly over 7 years. During the lease term, payments collected from the lessee will be applied directly to the repayment of principal and interest on the term loan credit facility. The Aircraft Held for Operating Lease, as well as the related lease payments received from the lessee, are pledged as collateral. During the six months ended June 30, 2023, the Company recorded $1,820 in debt issuance costs associated with the term loan credit facility.

The interest rate on the term loan credit facility is determined by using a base rate, which resets monthly, plus an applicable margin, and a fixed credit spread adjustment of 0.1%. The applicable margin during the lease term is fixed at 3.75%, and is subsequently reduced to 3.25% once the aircraft have been redelivered to the Company and a Loan-to-Value ("LTV") ratio calculation is completed at the end of the lease term. The interest rate in effect as of June 30, 2023 on the term loan was 8.9%. To the extent that the LTV exceeds 75% at the end of the lease term, a principal prepayment will be required in order to reduce the ratio to 75%. Amounts received under the end of lease maintenance compensation clause may be applied towards the LTV payment.

Pass-Through Trust Certificates

During March 2022, the Company arranged for the issuance of the 2022-1 EETC in an aggregate face amount of $188,277 for the purpose of financing or refinancing 13 aircraft. The Company is required to make bi-annual principal and interest payments each March and September, through March 2031. These notes bear interest at an annual rate between 4.84% and 5.75%. The weighted average interest rate was 5.06% as of June 30, 2023.

In December 2019, the Company arranged for the issuance of Class A, Class B and Class C trust certificates Series 2019-1 (the “2019-1 EETC”), in an aggregate face amount of $248,587 for the purpose of financing or refinancing 13 used aircraft, which was completed in 2020. The Company is required to make bi-annual principal and interest payments each June and December, through December 2027. These notes bear interest at an annual rate between 4.13% and 6.95%. The weighted average interest rate was 4.69% as of June 30, 2023.

The fair value of the Company’s debt was based on the discounted amount of future cash flows using the Company’s end-of-period estimated incremental borrowing rate for similar obligations. The estimates were primarily based on Level 3 inputs.

7. STOCK-BASED COMPENSATION

Stock compensation expense was $4,415 and $575, during the three months ended June 30, 2023 and June 30, 2022, respectively; and $7,093 and $1,495 during the six months ended June 30, 2023 and June 30, 2022, respectively. During the three months ended June 30, 2023, all conditions associated with the time-based and performance-based options granted under the SCA Acquisition Holdings, LLC Amended and Restated Equity Incentive Plan were met. As a result, 100% of the performance-based stock options and all remaining unvested time-based options vested. Therefore, during the three months ended June 30, 2023, the Company recognized an acceleration of stock-based compensation expense for the time-based and performance-based stock options totaling $2,960.

As of June 30, 2023, there was $8,661 of total unrecognized compensation expense related to Restricted Stock Units ("RSUs"). This unrecognized compensation is expected to be fully recognized over a weighted average period of approximately 2.3 years.

10.    INCOME TAXES

The Company's effective tax rate for both the three and six months ended June 30, 2023 was 22.9%. The effective tax rate for the three and six months ended June 30, 2022 was 19.0% and 118.1%, respectively. The effective tax rate represents a blend of federal and state taxes and includes the impact of certain nondeductible or nontaxable items. The effective tax rates for the three and six months ended June 30, 2022 were primarily impacted by the $1,700 and $8,500 non-deductible adjustments to increase the tax receivable liability related to the Tax Receivable Agreement (the "Tax Receivable Agreement" or "TRA"), respectively.

Tax Receivable Agreement

The TRA balance as of June 30, 2023 and December 31, 2022 was $101,020 and $103,800, respectively. The TRA liability is an estimate and actual amounts payable under the Tax Receivable Agreement could differ from this estimate. During the six months ended June 30, 2023, the Company recorded an immaterial adjustment to the estimated TRA liability. During the six months ended June 30, 2022, the Company recorded an $8,500 adjustment to increase the estimated TRA liability. During the six months ended June 30, 2023, the Company made a payment of $2,425 to the pre-IPO stockholders (the “TRA holders”), which includes certain members of the Company's management and certain members of the Company's Board of Directors. The payment is included within Financing Activities on the Condensed Consolidated Statements of Cash Flows. Payments will be made in future periods as attributes that existed at the time of the IPO (the “Pre-IPO Tax Attributes”) are utilized.

Amazon Agreement

On December 13, 2019, the Company signed a six-year contract (with two, two-year extension options, for a maximum term of 10 years) with Amazon to provide cargo services under the ATSA. In connection with the ATSA, the Company issued warrants to Amazon to purchase an aggregate of up to 9,482,606 shares of common stock at an exercise price of approximately $15.17 per share. During the six months ended June 30, 2023 and June 30, 2022, 442,521 and 379,304 warrants vested, respectively. As of June 30, 2023 and June 30, 2022, the cumulative vested warrants held by Amazon were 2,844,789 and 2,022,964, respectively. The exercise period of these warrants is through the eighth anniversary of the issue date.

12.    COMMITMENTS AND CONTINGENCIES

The Company has contractual obligations and commitments primarily with regard to lease arrangements, repayment of debt (see Note 6), payments under the TRA (see Note 10), and probable future purchases of aircraft.

As of June 30, 2023, the Company had a commitment to lease three aircraft with deliveries spanning the fourth quarter of 2023 and the first quarter of 2024. The leases will each have annual lease payments of approximately $2,000 for six years.

During the twelve months ended June 30, 2022, the compensation payable to an executive officer temporarily exceeded the restrictions on the payment of certain executive compensation under the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). Once the issue was identified, the executive officer voluntarily rescinded the unvested portion of the equity grant that caused the executive’s compensation to exceed the CARES Act limit. At no point did the executive's cash compensation and equity awards that could be monetized exceed the CARES Act limit. The Company did not accrue any amounts related to this matter as of June 30, 2023. To the extent we are deemed to have failed to remain in full

compliance with the CARES Act and the applicable rules and regulations thereunder, we may become subject to fines or other enforcement actions.

The Company is subject to various legal proceedings in the normal course of business and expenses legal costs as incurred. Management does not believe these proceedings will have a materially adverse effect on the Company.

14.    SUBSEQUENT EVENTS

The Company evaluated subsequent events for the period from the Balance Sheet date through August 4, 2023, the date that the Condensed Consolidated Financial Statements were available to be issued.

The Company executed a purchase amendment for an aircraft lease subsequent to June 30, 2023. The purchase amendment added a purchase obligation for the aircraft at the end of the lease term, which modified the classification of this lease from an operating lease to a finance lease. The amended aircraft lease has an expiration date in fiscal year 2024.

Subsequent to June 30, 2023, the Company's Board of Directors authorized the addition of $30,000 to the Company's existing stock repurchase program, which increased the total amount of authorization remaining to repurchase shares of the Company's Common Stock to $32,759. The stock repurchase program has no expiration date and may be modified, suspended, or terminated at any time.

Unless otherwise indicated, the terms “Sun Country,” “we,” “us” and “our” refer to Sun Country Airlines Holdings, Inc., and its subsidiaries.

Forward-Looking Statements

The following discussion and analysis presents factors that had a material effect on our results of operations during the six months ended June 30, 2023 and 2022. Also discussed is our financial position as of June 30, 2023 and December 31, 2022. This section should be read in conjunction with our unaudited Condensed Consolidated Financial Statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our audited Consolidated Financial Statements and related notes and discussion under the heading, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2022 10-K. This discussion contains forward-looking statements that involve risk, assumptions and uncertainties, such as statements of our plans, objectives, expectations, intentions and forecasts. Our actual results and the timing of selected events could differ materially from those discussed in these forward-looking statements as a result of several factors, including those set forth under the section of this report titled, “Risk Factors” and elsewhere in this report. You should carefully read the “Risk Factors” included in our 2022 10-K to gain an understanding of the important factors that could cause actual results to differ materially from our forward-looking statements.

Business Overview

Sun Country is a new breed of hybrid low-cost air carrier that dynamically deploys shared resources across our synergistic scheduled service, charter, and cargo businesses. By doing so, we believe we are able to generate high growth, high margins and strong cash flows with greater resilience than other passenger airlines. Based in Minnesota, we focus on serving leisure and visiting friends and relatives ("VFR") passengers and charter customers and providing crew, maintenance and insurance (“CMI”) services, with flights throughout the United States and to destinations in Canada, Mexico, Central America and the Caribbean. We share resources, such as flight crews, across our scheduled service, charter and cargo business lines with the objective of generating higher returns and margins and mitigating the seasonality of our route network. We optimize capacity allocation by market, time of year, day of week and line of business by shifting flying to markets during periods of peak demand and away from markets during periods of low demand with far greater frequency than nearly all other large U.S. passenger airlines. We believe our flexible business model generates higher returns and margins while also providing greater resiliency to economic and industry downturns than a traditional scheduled service carrier.

Our scheduled service business combines low costs with a high-quality product to generate higher Total Revenue per Available Seat Mile (“TRASM”) than Ultra Low-Cost Carriers ("ULCCs", which include Allegiant Travel Company, Frontier Airlines and Spirit Airlines) while maintaining lower Adjusted Cost per Available Seat Mile (“CASM”) than Low Cost Carriers ("LCCs", which include Southwest Airlines and JetBlue Airways), resulting in best-in-class unit profitability. Our business includes many cost characteristics of ULCCs, such as an unbundled product (which means we offer a base fare and allow customers to purchase Ancillary products and services for an additional fee), point-to-point service and a single-family fleet of Boeing 737-NG aircraft, which allow us to maintain a cost base comparable to these ULCCs. However, we offer a high-quality product that we believe is superior to ULCCs and consistent with that of LCCs. For example, our product includes more average legroom than ULCCs, complimentary beverages, complimentary in-flight entertainment, and in-seat power, none of which are offered by ULCCs.

Our charter business, which is one of the largest narrow body charter operations in the United States, is a key component of our strategy because it provides both inherent diversification and downside protection, and

-23-

SUN COUNTRY AIRLINES HOLDINGS, INC

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(Dollars in thousands, except per share amounts)

(Unaudited)

because it is synergistic with our other businesses. Our charter business has several favorable characteristics, including: large repeat customers, more stable demand than scheduled service flying, and the ability to pass through certain costs, including fuel. Our diverse charter customer base includes casino operators, the U.S. Department of Defense, and collegiate and professional sports teams. Our charter business includes ad hoc, repeat, short-term and long-term service contracts with pass-through fuel arrangements and annual rate escalations. Most of our business is non-cyclical because the U.S. Department of Defense and sports teams continue to fly during normal economic downturns and our casino contracts are long-term in nature.

On December 13, 2019, we signed the ATSA with Amazon to provide air cargo services. Flying under the ATSA began in May 2020 and we are currently flying 12 Boeing 737-800 cargo aircraft for Amazon. Our CMI service is asset-light from a Sun Country perspective as Amazon supplies the aircraft and covers many of the operating expenses, including fuel, and provides all cargo loading and unloading services. We are responsible for flying the aircraft under our air carrier certificate, crew, aircraft line maintenance and insurance, all of which allow us to leverage our existing operational expertise from our passenger businesses. Our cargo business also enables us to leverage certain assets, capabilities, and fixed costs to enhance profitability and promote growth across our Company.

Operations in Review

We believe a key component of our success is establishing Sun Country as a high growth, low-cost carrier in the United States by attracting customers with low fares and garnering repeat business by delivering a high-quality passenger experience, offering state-of-the-art interiors, complementary streaming of in-flight entertainment to passenger devices, seat reclining and seat-back power in all of our aircraft.

Pilot training throughput issues and the impact of macroeconomic conditions, including inflationary pressures, continue to impact the Company, as well as the industry. Airline travel demand has remained strong which has offset the additional costs associated with pilot training throughput issues and other inflationary pressures. Our flexible business model gives us the ability to adjust our services in response to these market conditions, which is targeted at producing the highest possible returns for Sun Country.

Total Operating Revenues increased $42,019, or 19%, to $261,086 for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022. The revenue increase was largely driven by a 22% increase in average passenger aircraft in the period and demand for our passenger service offerings during the second quarter of 2023 as compared to the second quarter of 2022. The increase in demand resulted in an increase to average total fare per passenger of $4.70, or 3%, to $177.33 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022, as well as a 2.0 percentage point increase in

passenger load factor over the same period. Passenger segment departures and block hours increased by 16% and 11%, respectively.

Scheduled Service. Scheduled service revenue increased $3,055, or 3%, to $111,467 for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022. The table below presents select operating data for scheduled service, expressed as quarter-over-quarter changes:

	Three Months Ended June 30,						Change			% Change
	2023			2022
Departures	6,401			5,674			727			13	%
Passengers	1,005,126			884,088			121,038			14	%
Average base fare per passenger	$	110.90		$	122.63		$	(11.73)		(10)	%

TRASM (cents)	12.74			11.55			1.19			10	%
Passenger load factor	85.8		%	83.8		%	2.0		pts	N/A

The quarter-over-quarter increases in certain Scheduled Service operating data were primarily the result of an increase in demand and capacity in the second quarter of 2023 relative to the same period in 2022. The quarter-over-quarter increase in demand is demonstrated by a 14% increase in passengers and a 2.0 percentage point increase in passenger load factor. The increase in demand supported the 13% and 6% increase in departures and ASMs, respectively, as a result of the 22% quarter-over-quarter increase in the average passenger aircraft for the period. The quarter-over-quarter Scheduled Service revenue increase was offset by the introduction of a new Ancillary product during the second quarter of 2022, which reclassified approximately $21,374 of revenue from Scheduled Service to Ancillary during the three months ended June 30, 2023, as compared to $5,552 during the three months ended June 30, 2022.

Charter Service. Charter Service revenue increased $6,877, or 16%, to $49,626 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase in Charter service revenue was driven by a 24% and 23% increase in Charter Service block hours and departures, respectively, as a result of increased activity with long-term charter customers. These increases were slightly offset by a 6% decrease quarter-over-quarter in Charter revenue per block hour as lower fuel prices impacted revenue due to the nature of the contractual fuel pass-through.

Ancillary. Ancillary revenue increased $22,572, or 51%, to $66,773 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. Ancillary revenue was $66.43 per passenger in the three months ended June 30, 2023, up $16.43 or 33%, from the three months ended June 30, 2022. Ancillary revenue benefited from the introduction of a new Ancillary product during the second quarter of 2022, which reclassified approximately $21,374 of revenue from Scheduled Service to Ancillary during the three months ended June 30, 2023, as compared to $5,552 during the three months ended June 30, 2022. The increase in Scheduled Service passengers during the period resulted in a higher volume of sales for air travel-related services, such as baggage fees, seat selection and upgrade fees, priority check-in and boarding fees, itinerary service fees, other fees and on-board sales. The increase in revenue was further supported by rate increases for our Ancillary products.

Cargo. Revenue from Cargo services increased $3,827, or 18%, to $25,017 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase was primarily driven by a 18% and 10% quarter-over-quarter increase in departures and block hours, respectively. Revenue during the three

months ended June 30, 2023 also benefited from the annual rate escalation included in the ATSA, which went into effect on December 13, 2022.

Other. Other revenue increased $5,688, or 226%, to $8,203 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. Other revenue benefited from the $5,871 of rental revenue associated with the five Aircraft Held for Operating Lease acquired during the first half of 2023.

Operating Expenses

Aircraft Fuel. We believe Aircraft Fuel expense, excluding indirect fuel credits, is the best measure of the effect of fuel prices on our business as it consists solely of direct fuel expenses that are related to our operations and is consistent with how management analyzes our operating performance. This measure is defined as GAAP Aircraft Fuel expense, excluding indirect fuel credits that are recognized within Aircraft Fuel expense, but are not directly related to our Fuel Cost per Gallon.

The primary components of Aircraft Fuel expense are shown in the following table:

	Three Months Ended June 30,				Change		% Change
	2023		2022
Total Aircraft Fuel Expense	$	52,360	$	76,947	$	(24,587)	(32)	%
Indirect Fuel Credits	212		208		4		2	%
Aircraft Fuel Expense, Excluding Indirect Fuel Credits	$	52,572	$	77,155	$	(24,583)	(32)	%
Fuel Gallons Consumed (thousands)	19,399		17,568		1,831		10	%
Fuel Cost per Gallon, Excluding Indirect Fuel Credits	$	2.71	$	4.39	$	(1.68)	(38)	%

Aircraft Fuel expense decreased 32% quarter-over-quarter primarily due to a 38% decrease in the average fuel cost per gallon, partially offset by and a 10% increase in consumption. The price of fuel during the three months ended June 30, 2022 was significantly impacted by global geopolitical events.

Salaries, Wages, and Benefits. Salaries, Wages, and Benefits expense increased $15,621, or 26%, to $75,919 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The quarter-over-quarter increase in Salaries, Wages, and Benefits was impacted by an increase in employee headcount, an acceleration of stock-based compensation expense recognized during the three months ended June 30, 2023 for our time-based and performance-based stock options and increased per unit costs for pilots and flight crews to support the current flight schedule. For more information on the acceleration of stock-based compensation for our time-based and performance-based stock options, see Note 7 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Aircraft Rent. Aircraft Rent expense decreased $1,432, or 65%, to $779 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. Aircraft Rent expense decreased primarily due to the composition of our aircraft fleet shifting from aircraft under operating leases (expense is recorded within Aircraft Rent) to owned aircraft or finance leases (expense is recorded through Depreciation and Amortization and Interest Expense). As of June 30, 2023 and 2022, we operated one and four aircraft under operating leases, respectively.

Maintenance. Maintenance expense increased $3,160, or 25%, to $15,942 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase in Maintenance expense was

(Unaudited)

primarily driven by higher line maintenance costs due to the quarter-over-quarter increase in the size of our fleet and operations, as well as the timing of heavy maintenance events and unscheduled repairs.

Sales and Marketing. Sales and Marketing expense increased $626, or 8%, to $8,507 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The change quarter-over-quarter was driven by an increase of approximately $1,000 in credit card processing and other travel agent fees, as a result of the 14% increase in passengers.

Depreciation and Amortization. Depreciation and Amortization expense increased $5,501, or 33%, to $22,355 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase was primarily due to the impact of a change in the composition of our aircraft fleet that results in an increased number of owned aircraft and aircraft under finance leases (the expense is recorded as Depreciation and Amortization and Interest Expense). As of June 30, 2023 and 2022, there were 47 and 37 aircraft that were owned or under finance leases, respectively.

Ground Handling. Ground Handling expense increased $3,099, or 38%, to $11,311 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase was primarily driven by the 16% increase in Passenger segment departures as a result of our expanding operations, as well as rate increases due to inflationary and market pressures.

Landing Fees and Airport Rent. Landing Fees and Airport Rent increased $3,466, or 36%, to $12,962 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase was primarily driven by the 16% increase in Passenger segment departures as a result of our expanding operations, as well as rate increases due to inflationary and market pressures.

Other Operating, net. Other operating, net increased $4,347, or 21%, to $25,364 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022, primarily due to increases in costs associated with our operational growth and related inflationary pressures, as well as an increase in third-party vendor spend.

Non-operating Income (Expense)

Interest Income. Interest income increased $2,013, or 378%, to $2,545 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The increase was primarily due to the change in our investment strategy, which led to the purchase of debt securities in May 2022, as well as an increases in the number of investments held and interest rates.

Interest Expense. Interest expense increased $4,197, or 60%, to $11,239 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The change was primarily due to a 24% increase in owned aircraft that were financed or refinanced with debt proceeds. For more information on the Company's Debt, see Note 6 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Other, net. Other, net decreased $1,559, or 92% to a net expense of $143 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The decrease was primarily due to the $1,700 adjustment to increase the estimated TRA liability in the prior year.

Income Tax. The Company's effective tax rate for the three months ended June 30, 2023 was 22.9% compared to 19.0% for the three months ended June 30, 2022. The increase in the effective tax rate was primarily due to the $1,700 non-deductible adjustment of the TRA liability in the prior period, partially offset by stock compensation benefits. For more information on the TRA liability, see Note 10 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Total Operating Revenues increased $109,610, or 25%, to $555,201 for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022. The revenue increase was largely driven by an increase in demand for our passenger service offerings during the first half of 2023 as compared to the first half of 2022. The increase in demand resulted in an increase to average total fare per passenger of $21.24, or 12%, to $199.33 for the six months ended June 30, 2023 as compared to 2022, as well as a 5.6 percentage point increase in passenger load factor over the same period.

Scheduled Service. Scheduled Service revenue increased $31,645, or 14%, to $264,124 for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022. The table below presents select operating data for Scheduled Service, expressed as year-over-year changes:

	Six Months Ended June 30,						Change			% Change
	2023			2022
Departures	12,578			11,901			677			6	%
Passengers	2,003,364			1,806,740			196,624			11	%
Average base fare per passenger	$	131.84		$	128.67		$	3.17		2	%
RPMs (thousands)	2,648,392			2,464,490			183,902			7	%

TRASM (cents)	13.31			10.82			2.49			23	%
Passenger load factor	87.0		%	81.4		%	5.6		pts	N/A

The year-over-year increases in certain Scheduled Service operating data were primarily the result of an increase in demand year-over-year. The year-over-year increase in demand is demonstrated by an 11% increase in passengers, a 5.6 percentage point increase in passenger load factor, and a 2% increase in the average base fare per passenger. The year-over-year Scheduled Service revenue increase is slightly offset by the introduction of a new Ancillary product during the second quarter of 2022, which reclassified approximately $38,598 of revenue from Scheduled Service to Ancillary during the six months ended June 30, 2023, as compared to $5,552 during the six months ended June 30, 2022.

Charter Service. Charter service revenue increased $20,185, or 27%, to $95,813 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The increase in Charter Service revenue was driven by a 33% and 28% increase in Charter Service departures and block hours, respectively. Charter Service revenue per block hour was materially consistent year-over-year.

Ancillary. Ancillary revenue increased $45,911, or 51%, to $135,198 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. Ancillary revenue was $67.49 per passenger in the six months ended June 30, 2023, up $18.07 or 37%, from the six months ended June 30, 2022. Ancillary revenue benefited from the introduction of a new Ancillary product during the second quarter of 2022, which reclassified approximately $38,598 of revenue from Scheduled Service to Ancillary during the six months ended June 30, 2023, as compared to $5,552 during the six months ended June 30, 2022. The increase in Scheduled Service passengers during the period resulted in greater sales of air travel-related services, such as baggage fees, seat selection and upgrade fees, priority check-in and boarding fees, itinerary service fees, other fees and on-board sales. The increase in Ancillary revenue was further supported by rate increases for our Ancillary products.

Cargo. Revenue from Cargo services increased $6,135, or 15%, to $48,378 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The increase was primarily driven by an 18% and 8% increase in Cargo departures and block hours, respectively. Revenue during the six months ended June 30, 2023 also benefited from the annual rate escalation included in the ATSA, which went into effect on December 13, 2022.

Other. Other revenue increased $5,734, or 96%, to $11,688 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. Other revenue in the current year benefited from $5,871 of rental revenue associated with the five Aircraft Held for Operating Lease acquired during the first half of 2023.

Operating Expenses

Aircraft Fuel. We believe Aircraft Fuel expense, excluding indirect fuel credits, is the best measure of the effect of fuel prices on our business as it consists solely of direct fuel expenses that are related to our operations and is consistent with how management analyzes our operating performance. This measure is defined as GAAP Aircraft Fuel expense, excluding indirect fuel credits that are recognized within Aircraft Fuel expense, but are not directly related to our Fuel Cost per Gallon.

The primary components of Aircraft Fuel expense are shown in the following table:

	Six Months Ended June 30,				Change		% Change
	2023		2022
Total Aircraft Fuel Expense	$	124,650	$	141,492	$	(16,842)	(12)	%
Indirect Fuel Credits	651		526		125		24	%
Aircraft Fuel Expense, Excluding Indirect Fuel Credits	$	125,301	$	142,018	$	(16,717)	(12)	%
Fuel Gallons Consumed (thousands)	40,472		37,813		2,659		7	%
Fuel Cost per Gallon, Excluding Indirect Fuel Credits	$	3.10	$	3.76	$	(0.66)	(18)	%

Aircraft Fuel expense decreased by 12% year-over-year primarily due to a 18% decrease in the average fuel cost per gallon, slightly offset by a 7% increase in consumption. The price of fuel during the six months ended June 30, 2022 was significantly impacted by global geopolitical events.

Salaries, Wages, and Benefits. Salaries, Wages, and Benefits expense increased $31,434, or 26%, to $151,349 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The year-over-year increase in Salaries, Wages, and Benefits was impacted by an increase in employee headcount, an acceleration of stock-based compensation expense recognized during the six months ended June 30, 2023 for our time-based and performance-based stock options and increased per unit costs for pilots and flight crews to support the current flight schedule. For more information on the acceleration of stock-based compensation for our time-based and performance-based stock options, see Note 7 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Aircraft Rent. Aircraft Rent expense decreased $3,138, or 58%, to $2,259 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. Aircraft Rent expense decreased primarily due to the composition of our aircraft fleet continuing to shift from aircraft under operating leases (expense is recorded within Aircraft Rent) to owned aircraft or finance leases (expense is recorded through Depreciation and Amortization and Interest Expense). As of June 30, 2023 and 2022, we operated one and four aircraft under operating leases, respectively.

Maintenance. Maintenance expense increased $4,204, or 17%, to $28,981 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The increase in Maintenance expense was primarily driven by higher line maintenance costs due to the year-over-year increase in the size of our fleet and operations, as well as an increase in unscheduled repair events.

Sales and Marketing. Sales and Marketing expense increased $1,927, or 12%, to $18,436 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The year-over-year increase was driven by an approximately $2,900 increase in credit card processing and other travel agent fees, as a result of

the 11% increase in passengers. These increases were partially offset by a decrease in global distribution system expenses due to a new indirect distribution method that reduced the fees paid for bookings.

Depreciation and Amortization. Depreciation and Amortization expense increased $9,633, or 30%, to $41,815 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The increase was primarily due to the impact of a change in the composition of our aircraft fleet that results in an increased number of owned aircraft and aircraft under finance leases (the expense is recorded as Depreciation and Amortization and Interest Expense). As of June 30, 2023 and 2022, there were 47 and 37 aircraft that were owned or under finance leases, respectively.

Ground Handling. Ground Handling expense increased $6,179, or 38%, to $22,349 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The increase was primarily driven by the 12% increase in Passenger segment departures as a result of our expanding operations, as well as rate increases due to inflationary and market pressures.

Landing Fees and Airport Rent. Landing Fees and Airport Rent increased $5,231, or 26%, to $25,013 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The increase was primarily driven by the 12% increase in Passenger segment departures as a result of our expanding operations, as well as rate increases due to inflationary and market pressures.

Other Operating, net. Other operating, net increased $4,813, or 11%, to $48,979 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022, primarily due to increases in costs associated with our operational growth and related inflationary pressures, as well as an increase in third-party vendor spend. These increases were partially offset by an increase in Charter Service recovery costs as a result of an increase in certain Charter Service departures.

Non-operating Income (Expense)

Interest Income. Interest income was $5,286 for the six months ended June 30, 2023 primarily due to the change in our investment strategy, which led to the purchase of debt securities in May 2022.

Interest Expense. Interest expense increased $4,265, or 27%, to $19,869 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The change was primarily due to a 24% increase in owned aircraft that were financed or refinanced with debt proceeds, partially offset by a $1,557 loss on extinguishment of debt incurred during the six months ended June 30, 2022 related to the repayment of the DDTL. For more information on the Company's Debt, see Note 6 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Other, net. Other, net decreased $8,222, or 96% to a net expense of $355 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. The decrease was primarily due to the $8,500 adjustment to increase the estimated TRA liability incurred during the prior year, partially offset by offering expenses of $640 in connection with the secondary offering during the first quarter of 2023.

Income Tax. The Company's effective tax rate for the six months ended June 30, 2023 was 22.9% compared to 118.1% for the six months ended June 30, 2022. The decrease in the effective tax rate was primarily due to the $8,500 non-deductible adjustment of the TRA liability in the prior period, partially offset by stock compensation benefits. For more information on the TRA liability, see Note 10 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Passenger. Passenger Operating Income increased $33,882 to $37,515 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. The Operating Margin Percentage for the three months ended June 30, 2023 increased 14.1 percentage points, as compared to the three months ended June 30, 2022. The increases in Passenger Operating Income and Operating Margin were driven by an increase in the average passenger aircraft in the period and demand for passenger service during the second quarter of 2023, as compared to the same period of 2022. This resulted in a significant increase in departures and passengers with relatively similar quarter-over-quarter per unit revenues for both Scheduled Service and Charter Service. Passenger Operating Income and Operating Margin for the three months ended June 30, 2023 also benefited from a 32% quarter-over-quarter decrease in Aircraft Fuel expense due to a 38% decrease in the average fuel cost per gallon, partially offset by and a 10% increase in consumption. The price of fuel during the three months ended June 30, 2022 was significantly impacted by global geopolitical events. For more information on the changes in the components of Operating Income for the Passenger segment, refer to the Results of Operations discussion above.

Cargo. Cargo Operating Loss increased by $1,664, to $1,928 for the three months ended June 30, 2023, as compared to the three months ended June 30, 2022. Operating Margin Percentage for the three months ended June 30, 2023 decreased 6.5 percentage points, as compared to the three months ended June 30, 2022. The decrease was primarily driven by a quarter-over-quarter increase in Salaries, Wages, and Benefits due to an increase in employee head count, as well as per unit costs for pilots to support operations. For more information on the components of Operating Income for the Cargo segment, refer to the Results of Operations discussion above.

Passenger. Passenger Operating Income increased $71,616 to $95,367 for the six months ended June 30, 2023, as compared to the six months ended June 30, 2022. Passenger Operating Margin Percentage for the six months ended June 30, 2023 increased 12.9 percentage points, as compared to the six months ended June 30, 2022. The increase in Passenger Operating Income and Operating Margin was driven by an increase in demand for passenger service during the first half of 2023, as compared to the first half of 2022. Passenger Operating Income and Operating Margin for the six months ended June 30, 2023 also benefited from a 12% year-over-year decrease in Aircraft Fuel expense due to an 18% decrease in the average fuel cost per gallon, slightly offset by a 7% increase in consumption. The price of fuel during the six months ended June 30, 2022 was significantly impacted by global geopolitical events. For more information on the changes in the components of Operating Income for the Passenger segment, refer to the Results of Operations discussion above.

Cargo. Cargo had an Operating Loss of $3,997 for the six months ended June 30, 2023, as compared to Operating Income of $1,450 for the six months ended June 30, 2022, a decrease of $5,447. Operating Margin Percentage for the six months ended June 30, 2023 decreased 11.7 percentage points, as compared to the six months ended June 30, 2022. The decrease was primarily driven by a year-over-year increase in Salaries, Wages, and Benefits due to an increase in employee head count, an increase in per unit costs for pilots to support operations, and increased other operating expenses as a result of an increase in departures. For more information on the components of Operating Income for the Cargo segment, refer to the Results of Operations discussion above.

Non-GAAP Financial Measures

We sometimes use information that is derived from the Condensed Consolidated Financial Statements, but that is not presented in accordance with GAAP. We believe these non-GAAP measures provide a meaningful comparison of our results to others in the airline industry and our prior year results. Investors should consider these non-GAAP financial measures in addition to, and not as a substitute for, our financial performance measures prepared in accordance with GAAP. Further, our non-GAAP information may be different from the non-GAAP information provided by other companies. We believe certain charges included in our operating expenses on a GAAP basis make it difficult to compare our current period results to prior periods as well as future periods and guidance. The tables below show a reconciliation of non-GAAP financial measures used in this Report to the most directly comparable GAAP financial measures.

Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income (Loss) and Adjusted EBITDA

Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income (Loss), and Adjusted EBITDA are non-GAAP measures included as supplemental disclosure because we believe they are useful indicators of our operating performance. Derivations of Operating Income and Net Income 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.

The measures described above have limitations as analytical tools. Some of the limitations applicable to these measures include: they do not reflect the impact of certain cash and non-cash charges resulting from matters we consider not to be indicative of our ongoing operations; and other companies in our industry may calculate these non-GAAP measures differently than we do, limiting each measure’s usefulness as a comparative measure. Because of these limitations, the following non-GAAP measures should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP and may not be the same as or comparable to similarly titled measures presented by other companies due to the possible differences in the method of calculation and in the items being adjusted.

For the foregoing reasons, Adjusted Operating Income, Adjusted Operating Income Margin, Adjusted Net Income (Loss) and Adjusted EBITDA have significant limitations which affect their use as indicators of our profitability. Accordingly, readers are cautioned not to place undue reliance on this information.

CASM and Adjusted CASM

CASM is a key airline cost metric defined as operating expenses divided by total available seat miles. Adjusted CASM is a non-GAAP measure derived from CASM by excluding fuel costs, costs related to our cargo operations, depreciation recognized on our aircraft and flight equipment held for operating lease, stock-based compensation, certain commissions and other costs of selling our vacation products from this measure as these costs are unrelated to our airline operations and improve comparability to our peers. Adjusted CASM is an important measure used by management and by our Board of Directors in assessing quarterly and annual cost performance. Adjusted CASM is commonly used by industry analysts and we believe it is an important metric by which they compare our airline to others in the industry, although other airlines may exclude certain other costs in their calculation of Adjusted CASM. The measure is also the subject of frequent questions from investors.

Adjusted CASM excludes fuel costs. By excluding volatile fuel expenses that are outside of our control from our unit metrics, we believe that we have better visibility into the results of operations and our non-fuel cost initiatives. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can lead to a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management and investors to understand the impact and trends in company-specific cost drivers, such as labor rates, aircraft costs and maintenance costs, and productivity, which are more controllable by management.

We have excluded costs related to the cargo operations and depreciation recognized on our aircraft and flight equipment held for operating lease as these operations do not create ASMs. The cargo expenses in the reconciliation below are different from the total operating expenses for our Cargo segment in the “Segment Information” table presented above, due to several items that are included in the Cargo segment, but have been captured in other line items used in the Adjusted CASM calculation. The five Aircraft Held for Operating Lease

were acquired during the six months ended June 30, 2023. Depreciation expense on these aircraft materially began during the three months ended June 30, 2023. Adjusted CASM further excludes special items and other adjustments, as defined in the relevant reporting period, that are not representative of the ongoing costs necessary to our airline operations and may improve comparability between periods. We also exclude stock compensation expense when computing Adjusted CASM. The Company’s compensation strategy includes the use of stock-based compensation to attract and retain employees and executives and is principally aimed at aligning their interests with those of our stockholders and long-term employee retention, rather than to motivate or reward operational performance for any period. Thus, stock-based compensation expense varies for reasons that are generally unrelated to operational decisions and performance in any period.

As derivations of Adjusted CASM 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 Adjusted CASM as presented may not be directly comparable to similarly titled measures presented by other companies. Adjusted CASM should not be considered in isolation or as a replacement for CASM. For the aforementioned reasons, Adjusted CASM has significant limitations which affect its use as an indicator of our profitability. Accordingly, readers are cautioned not to place undue reliance on this information.

Liquidity and Capital Resources

The airline business is capital intensive. Our ability to successfully execute our business strategy is largely dependent on the continued availability of capital with attractive terms and maintaining sufficient liquidity. We have historically funded our operations and capital expenditures primarily through cash from operations, proceeds from stockholders’ capital contributions, the issuance of promissory notes, and debt financing.

Our primary sources of liquidity as of June 30, 2023 included our existing cash and cash equivalents of $86,930 and short-term investments of $158,177, our expected cash generated from operations, and the $24,650 of available funds from the Revolving Credit Facility. In addition, we had restricted cash of $7,281 as of June 30, 2023, which generally consists of cash received as prepayment for chartered flights that is maintained in separate escrow accounts in accordance with DOT regulations requiring that charter revenue receipts received

(Unaudited)

prior to the date of transportation are maintained in a separate third-party escrow account. The restrictions are released once the charter transportation is provided.

Our primary uses of liquidity are for operating expenses, capital expenditures, lease rentals and maintenance reserve deposits, debt repayments, working capital requirements, and other general corporate purposes. Our single largest capital expenditure requirement relates to the acquisition of aircraft. We do not maintain an aircraft order book; instead, we enter into aircraft transactions on an opportunistic basis based on market conditions, our prevailing level of liquidity and capital market availability. As a result, we are not locked into large future capital expenditures. We have historically acquired aircraft through operating leases, finance leases, and debt. Our management team retains broad discretion to allocate liquidity.

We believe that our unrestricted cash and cash equivalents, short-term investments, and availability under our Revolving Credit Facility, combined with expected future cash flows from operations, will be sufficient to fund our operations and meet our debt payment obligations for at least the next twelve months. However, we cannot predict what the effect on our business and financial position might be from a change in the competitive environment in which we operate or from events beyond our control, such as volatile fuel prices, economic conditions, pandemics, weather-related disruptions, the impact of airline bankruptcies, restructurings or consolidations, U.S. military actions, regulations, or acts of terrorism.

Aircraft – As of June 30, 2023, our fleet consisted of 60 Boeing 737-NG aircraft. This includes 43 aircraft in the passenger fleet, 12 cargo operated aircraft through the ATSA, and five Aircraft Held for Operating Lease. During the six months ended June 30, 2023, the Company acquired five of the Aircraft Held for Operating Lease for total consideration of approximately $158,000.

For more information on our fleet and probable future purchases of aircraft, see Note 4 and Note 12 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report. For more information on the purchase of five of the Aircraft Held for Operating Lease, see Note 5 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Maintenance Deposits - In addition to funding the acquisition of aircraft, we are required by certain of our aircraft lessors to fund reserves in cash in advance for scheduled maintenance to act as collateral for the benefit of lessors. Qualifying payments that are expected to be recovered from lessors are recorded as Lessor Maintenance Deposits on our Condensed Consolidated Balance Sheets. As of June 30, 2023, we had $39,309 of total Lessor Maintenance Deposits.

Investments - We invest our cash and cash equivalents in highly liquid securities with strong credit ratings. As of June 30, 2023, the Company held $151,461 of debt securities, all of which are classified as current assets because of their highly liquid nature and availability to be converted into cash to fund current operations. Given the significant portion of our portfolio held in cash and cash equivalents and the high credit quality of our debt security investments, we do not anticipate fluctuations in the aggregate fair value of our investments to have a material impact on our liquidity or capital position.

We also hold $6,716 of Certificates of Deposit that are included in Investments on the Condensed Consolidated Balance Sheets as of June 30, 2023.

Credit Facilities - We use our Credit Facilities to provide liquidity support for general corporate purposes and to finance the acquisition of aircraft.

As of June 30, 2023, the Company had $24,650 of the $25,000 Revolving Credit Facility available due to $350 being pledged to support a letter of credit, and no balance drawn. The Credit Agreement includes financial covenants that require a minimum trailing 12-month EBITDAR ($87,700 as of March 31, 2022 and beyond) and

-42-

SUN COUNTRY AIRLINES HOLDINGS, INC

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

(Dollars in thousands, except per share amounts)

(Unaudited)

a minimum liquidity of $30,000 at the close of any business day. The Company was in compliance with these covenants as of June 30, 2023.

Debt - At our discretion, we obtain debt financing through the issuance of pass-through trust certificates to purchase, or refinance aircraft. In December 2019, we issued the 2019-1 EETC, for the purpose of financing or refinancing 13 used aircraft. In March 2022, the Company issued the 2022-1 EETC for the purpose of financing or refinancing 13 aircraft.

During the six months ended June 30, 2023, we executed a term loan credit facility with a face amount of $119,200 for the purpose of financing the five Aircraft Held for Operating Lease. The loan is to be repaid monthly over 7 years. During the lease term, payments collected from the lessee will be applied directly to the repayment of principal and interest on the term loan credit facility. The Aircraft Held for Operating Lease, as well as the related lease payments received from the lessee, are pledged as collateral.

The interest rate on the term loan credit facility is determined by using a base rate, which resets monthly, plus an applicable margin, and a fixed credit spread adjustment of 0.1%. The applicable margin during the lease term is fixed at 3.75%, and is subsequently reduced to 3.25% once the aircraft have been redelivered to the Company and a LTV ratio calculation is completed at the end of the lease term. The interest rate in effect as of June 30, 2023 on the term loan was 8.9%. To the extent that the LTV exceeds 75% at the end of the lease term, a principal prepayment will be required in order to reduce the ratio to 75%. Amounts received under the end of lease maintenance compensation clause may be applied towards the LTV payment.

For more information on our credit facilities or debt, see Note 6 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

TRA Liability - During the six months ended June 30, 2023, we made a payment of $2,425 to the TRA holders. Payments will be made in future periods as Pre-IPO Tax Attributes are utilized. For more information on the TRA liability, see Note 10 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Operating Cash Flow Activities

Operating activities in the six months ended June 30, 2023 provided $95,693, as compared to $37,060 during the six months ended June 30, 2022. During the six months ended June 30, 2023, our Net Income was $58,946, as compared to a Net Loss of $285 during the six months ended June 30, 2022.

Our operating cash flow is primarily impacted by the following factors:

Seasonality of Advance Ticket Sales. We sell tickets for air travel in advance of the customer's travel date. When we receive a cash payment at the time of sale, we record the cash received on advance sales as deferred revenue in Air Traffic Liabilities. Air Traffic Liabilities typically increase during the fall and early winter months as advanced ticket sales grow prior to the late winter and spring peak travel season and decrease during the summer months. Most tickets can be purchased no more than twelve months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the six months ended June 30, 2023, $146,904 of revenue recognized in Passenger revenue was included in the $157,995 of Air Traffic Liabilities as of December 31, 2022. The balance of Air Traffic Liabilities increased year-over-year by 5% to $130,264 as of June 30, 2023. This is due to increased demand for passenger services, which has also resulted in higher per unit revenues.

Aircraft Fuel. Aircraft Fuel expense represented approximately 27% and 34% of our total operating expense for the six months ended June 30, 2023 and 2022, respectively. The market price for jet fuel is volatile, which can impact the comparability of our periodic cash flows from operations. Fuel cost per gallon decreased by 18% year-over-year due to the impact of global geopolitical events on the price of fuel during the six months ended

(Unaudited)

June 30, 2022. Fuel consumption increased by 7% during the six months ended June 30, 2023, compared to the prior year.

Investing Cash Flow Activities

Capital Expenditures. Our capital expenditures were $192,352 and $137,647 for the six months ended June 30, 2023 and 2022, respectively. Our capital expenditures during the six months ended June 30, 2023 primarily included the purchase of five Aircraft Held for Operating Lease and one incremental aircraft for our passenger fleet. Our capital expenditures during the six months ended June 30, 2022 primarily included the purchase of five incremental aircraft, the purchase of four spare engines, the first installment payment to purchase a flight simulator, and other miscellaneous projects.

Investments. During the six months ended June 30, 2023, the Company's net investment activity resulted in cash inflows of $22,358 due to maturing securities exceeding purchases of investments. This was the result of a change in our investment strategy during the second quarter of 2022, which led to the purchase of $71,629 of investments during the six months ended June 30, 2022.

Financing Cash Flow Activities

Debt. During the six months ended June 30, 2023, the Company executed a term loan credit facility with a face amount of $119,200 for the purpose of financing the five Aircraft Held for Operating Lease. In March 2022, the Company arranged for the issuance of the 2022-1 EETC in an aggregate face amount of $188,277 for the purpose of financing or refinancing 13 aircraft. Five of these aircraft were owned fleet assets previously financed by the DDTL, which was repaid with the proceeds from the 2022-1 EETC.

Finance Leases. Our repayments of finance lease obligations were $8,671 and $24,293 for the six months ended June 30, 2023 and 2022, respectively. During the six months ended June 30, 2022, the Company purchased one aircraft previously classified as a finance lease using proceeds from the 2022-1 EETC. The resulting cash outflows are recorded as payments for finance lease obligations. There were no similar transactions during the six months ended June 30, 2023. As of June 30, 2023 and 2022, there were 12 and 11 finance leases, respectively.

Common Stock Repurchases. During the six months ended June 30, 2023, the Company repurchased 1,166,751 shares of its Common Stock at a total cost of $22,249, or $19.07 per share. The repurchases were part of a secondary public offering of the Company's shares by the Apollo Stockholder, as well as open market purchases completed in the second quarter. For more information on the stock repurchase program and this purchase, see Note 11 of the Condensed Consolidated Financial Statements included in Part I, Item I of this report.

Other. During the six months ended June 30, 2023, the Company made a payment of $2,425 to the TRA holders.

Critical Accounting Policies and Estimates

Our unaudited Condensed Consolidated Financial Statements and the accompanying notes thereto included elsewhere in this Quarterly Report on Form 10-Q are prepared in accordance with GAAP. The preparation of the Condensed Consolidated Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ significantly from our estimates. To the extent that there are differences between our estimates and actual results, our future financial statement presentation, financial condition, results of operations, and cash flows will be affected. For more information on our critical accounting policies, see “Management’s Discussion and Analysis of Operations” sections within Part II, Item 7, respectively, in our 2022 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES 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 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. Accordingly, actual results may differ from the information provided below.

Aircraft Fuel. Unexpected pricing changes of aircraft fuel could have a material adverse effect on our business, results of operations and financial condition. To hedge the economic risk associated with volatile aircraft fuel prices, we periodically enter into fuel collars, which allows us to reduce the overall cost of hedging, but may prevent us from participating in the benefit of downward price movements. In the past, we have also entered into fuel option and swap contracts. We had no hedges in place at June 30, 2023. We do not hold or issue option or swap contracts for trading purposes. We currently do not expect to enter into these types of contracts prospectively, although significant changes in market conditions could affect our decisions. Based on our forecasted scheduled service and charter fuel consumption for the third quarter of 2023, we estimate that a one cent per gallon increase in the average aircraft fuel price would increase aircraft fuel expense by approximately $196 excluding reimbursed fuel from cargo and certain charter customers.

Interest Rates. We have exposure to market risk associated with changes in interest rates related to the interest expense from our variable-rate debt and our short-term investment securities. A change in market interest rates would impact interest expense under the $119,200 term loan credit facility used to finance the Aircraft Held for Operating Lease. A 100 basis point increase in interest rates on the term loan would result in a corresponding increase in interest expense of approximately $1,192 annually. As of the date of this filing, the entire term loan credit facility had been drawn. The Company also maintains a $25,000 Revolving Credit Facility with a variable interest rate that is impacted by market conditions. As of June 30, 2023, the Company had $24,650 of financing available through the Revolving Credit Facility, as $350 had been pledged to support a letter of credit. As of June 30, 2023, no amounts on the Revolving Credit Facility had been drawn.

Our short-term investment securities are primarily comprised of fixed-rate debt investments. An increase in market interest rates decreases the market value of fixed-rate investments. Conversely, a decrease in market interest rates increases the market value. The fair market value of our short-term investments with exposure to interest rate risk was $151,461 as of June 30, 2023. These investments are highly liquid and are available to be quickly converted into known amounts of cash to fund current operations. The Company limits its investments to investment grade quality securities. Given these factors and that a significant portion of our portfolio is held in cash and cash equivalents, we do not anticipate fluctuations in the aggregate fair value of our financial assets to have a material impact on our liquidity or capital position.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures represent controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (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 in our reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

In connection with the preparation of this Form 10-Q, pursuant to Rule 13a-15(b) of the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2023.

-47-

Based on the evaluation of our disclosure controls and procedures as of June 30, 2023, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of June 30, 2023, due to the material weaknesses in internal control over financial reporting described below.

Material Weaknesses in Internal Control over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

We previously disclosed in our Annual Report on Form 10-K as of December 31, 2022 that management identified a material weakness in the Company's internal control over financial reporting. Specifically, controls over the accounting for complex, non-routine transactions were not designed or implemented to operate with a sufficient level of precision. This included controls addressing the application of ASC Topic 842, Leases, to the purchase of aircraft subject to an existing operating lease.

During the quarter ended June 30, 2023, management identified an additional material weakness in the Company’s internal control over financial reporting. Specifically, the Company did not have an effective risk assessment process to identify and assess the risks of misstatement associated with the utilization of a third-party service organization's hosted IT solution for automating the processing of vendor invoices (i.e., scanning, routing, approving, and preparing the recording of invoices) and hosting of related information. As a result, management’s information technology general controls (“ITGCs”) over the IT application used by the service organization and process-level controls over the procurement activities carried out by the third-party service organization were not designed or implemented to operate at a sufficient level of precision. The Company also did not obtain a System and Organization Controls Report from the third-party that would provide evidence of design, implementation, and operating effectiveness of such controls within the service organization’s framework of internal controls.

These control deficiencies did not result in a material misstatement of the Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q or our prior period consolidated annual or interim financial statements. However, each of these control deficiencies create a reasonable possibility that a material misstatement to the annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Accordingly, management has concluded that each control deficiency constituted a material weakness in the Company's internal control over financial reporting and our internal control over financial reporting was not effective as of June 30, 2023.

Remediation Plan

Management is continuing to supplement and enhance the Company's system of internal control over financial reporting through actions responsive to each identified material weakness. The remediation plan for the material weakness associated with accounting for complex, non-routine transactions, includes the following:

•Hired a technical accounting specialist and manager after the material weakness occurred;

•Provided additional training on how to utilize external technical accounting research resources;

•Reviewed all existing internal accounting policies and accounting guidance memos for completeness and the appropriate accounting guidance, including those surrounding leases;

•Established a policy to provide additional guidance surrounding the use of third-party specialists;

•Enhanced the design of financial reporting controls, specifically sub-certifications and review of non-routine transactions including updating the lease accounting checklist;

•Engaging third-party specialists, as necessary, to review management’s analysis and conclusions on the accounting for non-routine transactions involving the application of complex accounting standards;

-48-

•Continuing to review and make necessary changes to the design of our risk assessment and review controls over accounting for complex, non-routine transactions, including lease-related transactions;

•Re-designed the overall design of our risk assessment process with utilization of a new third-party tool; and

•Established a policy and internal controls surrounding transactions related to a new lessor relationship.

We have made significant progress in accordance with our remediation plan related to the material weakness in controls over the accounting for complex, non-routine transactions since the filing of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2023 as follows:

•Continued to engage third-party technical accounting specialists to review management's conclusions on the accounting for non-routine transactions occurring in the second quarter of 2023; and

•Continued to enhance management's controls surrounding the accounting for complex, non-routine transactions, including those associated with the acquisition and related financing of additional aircraft, and those involved with becoming a first-time aircraft lessor.

The remediation plan for the material weakness associated with the controls over the utilization of a third-party service organization's hosted IT solution for automating the processing of vendor invoices and hosting of related information, includes the following:

•Understand the timing and scope of the third-party service organization's attestation report to determine whether the attestation will be adequate and performed in a timely manner to cover our fiscal year;

•Where a SOC attestation is not completed, explore alternative solutions including, but not limited to, a) bringing the application on premise so the necessary IT infrastructure and related processes and controls surrounding the IT application can be entirely within the Company’s control, and b) evaluating other service providers that are able to provide a SOC attestation report; and

•Enhance the design and operation of manual internal controls within the Company, including tracking and reviewing of vendor invoices outside of the third-party service organization’s application and processes, in the event an adequate and timely SOC attestation report is not available from the third-party service organization and other viable solutions are not pursued.

Each material weakness will not be considered remediated until a sustained period of time has passed to allow management to test the design and operating effectiveness of the new or enhanced controls implemented as a result of the corrective actions. We believe that our remediation plans will be sufficient to remediate the identified material weaknesses and strengthen our internal control over financial reporting. However, as we continue to evaluate and improve our internal control over financial reporting, management may determine that additional measures to address the identified control deficiencies or modifications to the remediation plans are necessary. Therefore, we cannot assure you when the Company will remediate the material weaknesses identified above, nor can we be certain that additional actions will not be required and what the costs of any such additional actions may be. Moreover, we cannot assure you that additional material weaknesses will not arise in the future.

Despite the existence of these material weaknesses, our management believes that the Condensed Consolidated Financial Statements included in this Quarterly Report present fairly, in all material respects, the Company's financial position, results of operations and cash flows for the periods presented in conformity with GAAP.

Changes in Internal Control Over Financial Reporting

Other than the changes made as part of the remediation plans described above, there has been no change in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

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 currently believe that 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.

ITEM 1A. RISK FACTORS

We have disclosed under the heading “Risk Factors” in our 2022 10-K and in our Quarterly Report on Form 10-Q for the period ended March 31, 2023 ("March 31, 2023 10-Q"), the risk factors which materially affect our business, financial condition or results of operations. Except for the updated risk factors set forth below, there have been no material changes from the risk factors previously disclosed. You should carefully consider the risk factors set forth in our 2022 10-K, March 31, 2023 10-Q, and the risk factors presented in this Quarterly Report on Form 10-Q. You should be aware that these risk factors and other information may not describe every risk facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Risks Related to Our Industry

We are subject to extensive regulation by the FAA, the DOT, the TSA, CBP 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 impose significant costs. In the last several years, Congress has passed laws and the FAA, DOT and TSA have issued regulations, orders, rulings and guidance relating to consumer protections and to the operation, safety, and security of airlines 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. 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 lengthy tarmac delays, consumer notice requirements, consumer complaints, price and airline advertising, distribution, oversales and involuntary denied boarding process and compensation, ticket refunds, liability for loss, delay or damage to baggage, customer service commitments, contracts of carriage and the transportation of passengers with disabilities.

For example, the DOT or FAA has pending proposed rulemakings and/or published final rules 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; 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; enhancing the transparency of airline ancillary service fees; airline ticket refunds and consumer protections; requiring that certain airplanes used to conduct domestic, flag, or supplemental passenger-carrying operations have installed a physical secondary barrier that protects the flightdeck from unauthorized intrusion when the flightdeck door is opened; and flight attendant duty period limitations and rest requirements. In addition, Congress is currently considering FAA Reauthorization legislation which may result in additional rules, regulations, and obligations. Failure to

-50-

remain in full compliance with these and other applicable rules and regulations may subject us to fines or other enforcement action or adversely affect our business, results of operations and financial condition.

Risks Related to Our Business

Major bank failure or sustained financial market illiquidity, or illiquidity at our clearing, cash management and custodial financial institutions, could adversely affect our business, financial condition and results of operations.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, the California Department of Financial Protection and Innovation closed Silicon Valley Bank (“SVB”) and appointed Federal Deposit Insurance Corporation (the “FDIC”) receiver. Similarly, on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership. Since that time, there have been reports of instability at other U.S. banks. Although the Federal Reserve Board, the Department of the Treasury and the FDIC have taken steps to ensure that depositors at SVB and Signature Bank can access all of their funds, including funds held in uninsured deposit accounts, and have taken additional steps to provide liquidity to other banks, there is no guarantee that, in the event of the closure of other banks or financial institutions in the future, depositors would be able to access uninsured funds or that they would be able to do so in a timely fashion and uncertainty and liquidity concerns in the broader financial services industry remain. The ultimate outcome of these events, and whether further regulatory actions will be taken, cannot be predicted.

We would face certain risks in the event of a sustained deterioration of financial market liquidity, as well as in the event of sustained deterioration in the liquidity, or failure, of our clearing, cash management and custodial financial institutions. In particular, in the event of a major bank or credit card failure, we could be unable to process credit card transactions. In such a case, or if financial liquidity deteriorates for other reasons, our ability to operate our business and our financial condition and results of operations could be significantly harmed.

Risks Related to Ownership of Our Common Stock

As disclosed, we have identified material weaknesses in our internal control over financial reporting and, if we are unable to remediate each material weakness, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

As disclosed in Part I, Item 4, “Controls and Procedures,” we have identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. Each control deficiency described below creates a reasonable possibility that a material misstatement to the annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Accordingly, management has concluded that each of these control deficiencies constituted a material weakness as of June 30, 2023. The previously disclosed material weakness relates to management's controls over the accounting for complex, non-routine transactions that were not designed or implemented to operate with a sufficient level of precision. This included controls addressing the application of ASC Topic 842, Leases, to the purchase of aircraft subject to an existing operating lease. The additional material weakness identified in the quarter ended June 30, 2023, relates to an ineffective risk assessment and lack of effective controls over the procurement process activities outsourced to a third-party service organization, including the information technology general controls (“ITGCs” over the automation of processing of vendor invoices (i.e., scanning, routing, approving, and preparing the recording of invoices) and hosting of related information.

Failure to have effective internal control over financial reporting and disclosure controls and procedures could impair our ability to produce accurate financial statements on a timely basis and could lead to a restatement of our financial statements. If, as a result of the ineffectiveness of our internal control over financial reporting and disclosure controls and procedures, we cannot provide reliable financial statements, our business decision processes may be adversely affected, our business and results of operations could be harmed, and investors

-51-

could lose confidence in our reported financial information. In addition, in some circumstances, failure to maintain effective internal control over financial reporting could result in investigations or sanctions by regulatory authorities.

Our management has implemented a remediation plan to address each material weakness, as described in Part I, Item 4. Such remediation measures may require additional time and resources and there is no assurance that these initiatives will ultimately have the intended effects. As management continues to evaluate and work to improve our internal control over financial reporting, management may determine that additional measures to address control deficiencies or modifications to the remediation plan are necessary. Therefore, we cannot assure you when the Company will remediate such weaknesses, nor can we be certain that additional actions will not be required or what costs of any such additional actions may be. In addition, there can be no assurance that such remediation efforts will be successful, that our internal control over financial reporting will be effective as a result of these efforts nor that additional material weaknesses will not arise in the future or that management has identified all material weaknesses. If we identify any new material weaknesses in the future, any such newly identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim financial statements. Any such future deficiencies identified may not be material weaknesses that would be required to be reported in future periods. In addition, we cannot assure you that our independent registered public accounting firm will be able to attest that such internal controls are effective when they are required to do so.

If we fail to remediate each material weakness and maintain effective internal control over financial reporting or disclosure controls and procedures, we may not be able to rely on the integrity of our financial results, which could result in inaccurate or late reporting of our financial results, as well as delays or the inability to meet our reporting obligations or to comply with SEC rules and regulations. Any of these could result in delisting actions by the Nasdaq Stock Market, investigation and sanctions by regulatory authorities, stockholder investigations and lawsuits, and could adversely affect our business and the trading price of our common stock. The potential consequences of any material weakness could have a material adverse effect on our business, results of operations and financial condition.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table summarizes the Company's repurchases of Common Stock for the quarter ended June 30, 2023. All stock repurchases during the quarter reflect shares repurchased pursuant to the Company's stock repurchase program and shares withheld from employees to satisfy the taxes due in connection with grants of stock under the Company's equity incentive plans. The shares of Common Stock withheld to satisfy tax withholding obligations are considered to be "issuer purchases" of shares that are required to be disclosed pursuant to this Item, but are not considered to be part of the Company's $50,000 stock repurchase program. For more information on the Company's stock repurchase program, see Note 11 to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

BASIS OF PRESENTATION

Sun Country Airlines Holdings, Inc. (together with its consolidated subsidiaries, "Sun Country" or the "Company") is the parent company of Sun Country, Inc., which is a certificated air carrier providing scheduled passenger service, air cargo service, charter air transportation and related services.

The Company has prepared the unaudited Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (“GAAP”) and has included the accounts of Sun Country Airlines Holdings, Inc. and its subsidiaries. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Form 10-Q. Therefore, the accompanying Condensed Consolidated Financial Statements of Sun Country Airlines Holdings, Inc. should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the SEC ("2022 10-K"). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited Condensed Consolidated Financial Statements for the interim periods presented. All material intercompany balances and transactions have been eliminated in consolidation.

The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

The Company completed its public float calculation for SEC reporting purposes as of June 30, 2023, as required. The Company will be a large accelerated filer as of December 31, 2023.

Due to impacts from seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, uncertainties in pilot staffing, the impact of macroeconomic conditions including inflationary pressures, and other factors, operating results for the six months ended June 30, 2023 are not necessarily indicative of operating results for future quarters or for the year ending December 31, 2023.

Revenue from Contract with Customer [Abstract]

REVENUE

REVENUESun Country is a certificated air carrier generating Operating Revenues from Scheduled service, Charter service, Ancillary, Cargo and Other revenue. Scheduled service revenue mainly consists of base fares. Charter service revenue is primarily generated through service provided to the U.S. Department of Defense, collegiate and professional sports teams, and casinos. Ancillary revenues consist of revenue earned from air travel-related services, such as: baggage fees, seat selection fees, passenger interface fees and on-board sales. Cargo consists of revenue earned from flying cargo aircraft for Amazon.com Services, Inc. (together with its affiliates, “Amazon”) under the Air Transportation Services Agreement (the “ATSA”). Other revenue consists primarily of revenue from services in connection with Sun Country Vacations products and rental revenue related to certain transactions where the Company acts as a lessor.

The significant categories comprising Operating Revenues are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Scheduled Service	$	111,467	$	108,412	$	264,124	$	232,479
Charter Service	49,626		42,749		95,813		75,628
Ancillary	66,773		44,201		135,198		89,287
Passenger	227,866		195,362		495,135		397,394
Cargo	25,017		21,190		48,378		42,243
Other	8,203		2,515		11,688		5,954
Total Operating Revenues	$	261,086	$	219,067	$	555,201	$	445,591

The Company attributes and measures its Operating Revenues by geographic region as defined by the Department of Transportation ("DOT") for airline reporting based upon the origin of each passenger and cargo flight segment.

The Company’s operations are highly concentrated in the U.S., but include service to many international locations, primarily based on scheduled service to Latin America during the winter season and on military charter services.

Total Operating Revenues by geographic region are as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Domestic	$	251,582	$	211,012	$	526,071	$	419,851
Latin America	9,451		8,014		28,555		25,634

Total Operating Revenues	$	261,086	$	219,067	$	555,201	$	445,591

Contract Balances

The Company’s contract assets primarily relate to costs incurred to get Amazon cargo aircraft ready for service. The balances are included in Other Current Assets and Other Assets on the Condensed Consolidated Balance Sheets.

The Company’s contract liabilities are comprised of: 1) ticket sales for transportation that has not yet been provided (reported as Air Traffic Liabilities on the Condensed Consolidated Balance Sheets), 2) outstanding loyalty points that may be redeemed for future travel and other non-air travel awards (reported as Loyalty Program Liabilities on the Condensed Consolidated Balance Sheets) and, 3) the Amazon Deferred Up-front Payment received (reported within Other Current Liabilities and Other Long-term Liabilities on the Condensed Consolidated Balance Sheets).

Contract Assets and Liabilities are as follows:

	June 30, 2023		December 31, 2022
Contract Assets
Costs to fulfill contract with Amazon	$	1,855	$	2,195
Total Contract Assets	$	1,855	$	2,195
Contract Liabilities
Air Traffic Liabilities	$	130,264	$	157,995
Loyalty Program Liabilities	13,656		15,437
Amazon Deferred Up-front Payment	2,764		3,271
Total Contract Liabilities	$	146,684	$	176,703

The balance in the Air Traffic Liabilities fluctuates with seasonal travel patterns. Most tickets can be purchased no more than twelve months in advance, therefore any revenue associated with tickets sold for future travel will be recognized within that timeframe. For the six months ended June 30, 2023, $146,904 of revenue was recognized in Passenger revenue that was included in the Air Traffic Liabilities as of December 31, 2022.

Loyalty Program

The Sun Country Rewards program provides loyalty awards to program members based on accumulated loyalty points. The Company records a liability for loyalty points earned by passengers under the Sun Country Rewards program using two methods: 1) a liability for points that are earned by passengers on purchases of the Company’s services is established by deferring revenue based on the redemption value, net of estimated loyalty points that will expire unused, or breakage; and 2) a liability for points attributed to loyalty points issued to the Company’s Visa card holders is established by deferring a portion of payments received from the Company’s co-branded agreement. The balance of the Loyalty Program Liabilities fluctuates based on seasonal patterns, which impacts the volume of loyalty points awarded through travel or issued to co-branded credit card and other partners (deferral of revenue) and loyalty points redeemed (recognition of revenue). Due to these reasons, the timing of loyalty point redemptions can vary significantly.

Changes in the Loyalty Program Liabilities are as follows:

	2023		2022
Balance – January 1	$	15,437	$	19,718
Loyalty Points Earned	4,262		3,471
Loyalty Points Redeemed (1)	(6,043)		(6,585)
Balance – June 30	$	13,656	$	16,604

______________________

(1) Loyalty points are combined in one homogenous pool, which includes both air and non-air travel awards, and are not separately identifiable. As such, the revenue recognized is comprised of points that were part of the Loyalty Program Liabilities balance at the beginning of the period, as well as points that were earned during the period.

(1)	One aircraft operating lease was reclassified into a finance lease, as further described below.
(2)	Two aircraft operating leases were reclassified into finance leases and a separate aircraft finance lease purchase option was exercised, resulting in a net change of one finance lease reclassification.

During the six months ended June 30, 2023, the Company acquired five 737-900ERs that are currently on lease to an unaffiliated airline ("Aircraft Held for Operating Lease"). The five Aircraft Held for Operating Lease were financed through a term loan arrangement. See Note 5 of these Condensed Consolidated Financial Statements for more information on this transaction. Additionally, during the six months ended June 30, 2023, the Company acquired an incremental aircraft and executed a lease amendment to purchase one aircraft at the end of its lease term. An additional aircraft purchase amendment was executed subsequent to June 30, 2023. The lease amendments modified the classification of these leases from operating leases to finance leases and have expiration dates in fiscal year 2024. Of the 35 Owned aircraft

and Aircraft Held for Operating Lease as of June 30, 2023, 31 were financed and four aircraft were unencumbered.

During the six months ended June 30, 2022, the Company executed lease amendments to purchase two aircraft at the end of the lease term, which modified the lease classification from operating leases to finance leases with expiration dates in fiscal year 2026 and retired one aircraft. Further, the Company purchased an aircraft previously classified as a finance lease using proceeds of the from the issuance of Class A and Class B pass-through trust certificates (the "2022-1 EETC"). The Company also acquired six incremental 737-800 aircraft, five of which were financed using proceeds from the 2022-1 EETC and another through a finance lease arrangement that is set to expire in fiscal year 2030.

Depreciation, amortization, and rent expense on aircraft are as follows:

		Three Months Ended June 30,				Six Months Ended June 30,

Business Combination and Asset Acquisition [Abstract]

ASSET ACQUISITIONS

ASSET ACQUISITIONS

During the six months ended June 30, 2023, the Company acquired five Aircraft Held for Operating Lease. The table below reflects the cumulative balances of the five aircraft as of the acquisition dates:

Asset	Balance Sheet Classification
Aircraft Held for Operating Lease	Aircraft and Flight Equipment Held for Operating Lease	$	114,628
Maintenance Rights Asset	Aircraft and Flight Equipment Held for Operating Lease	39,533
Over-Market Asset	Other Intangible Assets, net	3,741
Total		$	157,902

The purchase price was assigned to the assets based upon their relative fair values as of the acquisition date. The Company estimated the fair value of the Aircraft Held for Operating Lease principally based on market appraisals. The appraisals were based on an analysis of the economic conditions impacting both the airline industry and broader economy, the current fuel price environment, aircraft order data, passenger traffic levels, and qualitative and quantitative characteristics impacting the value of the acquired aircraft.

The fair value of the Maintenance Rights Asset was determined using a discounted cash flow method based on aircraft utilization levels at the time of the acquisition and the applicable rates as specified within the lease agreements.

The fair value of the Over-Market Asset was determined using a discounted cash flow model that involves the comparison of contractual lease cash flows to the estimated at-market lease payments for an aircraft of the same type and age.

The purchase of the Aircraft Held for Operating Lease was financed using the proceeds from a term loan credit facility with a face amount of $119,200 and the Company's cash. For more information on the term loan credit facility, see Note 6 of these Condensed Consolidated Financial Statements.

Aircraft Held for Operating Lease

The Company obtained outright ownership of the Aircraft Held for Operating Lease upon purchase and assumed the position of lessor until the end of the lease terms. The Company is entitled to fixed payments over the remaining lease term for each aircraft, which expire at various dates between the fourth quarter of 2024 and the fourth quarter of 2025. On each lease expiry date, the Aircraft Held for Operating Lease will be redelivered to Sun Country and are expected to be inducted into the Company’s fleet. The rental revenue associated with the Aircraft Held for Operating Lease is recognized as it is earned and is included in Other revenue. The Company has recognized $5,871 of rental revenue during the six months ended June 30, 2023.

Maintenance Rights Asset

Upon purchase of the Aircraft Held for Operating Lease, the Company recognized a Maintenance Rights Asset which represents the Company’s contractual right to receive the aircraft in a specified maintenance condition at the end of the lease. The acquired leases contain an end of lease compensation clause whereby the lessee is required to remit a cash payment to true-up the aircraft’s maintenance condition to full-life or perform the maintenance tasks needed to physically restore the airframe and engines to such a condition. The asset represents the difference between the Aircraft Held for Operating Lease’s physical maintenance condition as of the purchase date and the contractual return condition at the end of the lease term. The Maintenance Rights Asset is not depreciated over the lease term, nor will it accrete as additional life is consumed on the aircraft.

Over-Market Asset

Upon purchase of the Aircraft Held for Operating Lease, the Company recognized an intangible asset representing lease terms which are favorable to the lessor (unfavorable to the lessee), as compared with market terms of similar leases. The asset will be amortized over the remaining lease terms for the respective aircraft, which range from 1.4-2.4 years as of June 30, 2023. The amortization will be recognized as contra-revenue, offsetting the rental revenue associated with the Aircraft Held for Operating Lease included in Other revenue.

Debt Disclosure [Abstract]

DEBT

DEBT

Credit Facilities

On February 10, 2021, the Company executed a five-year credit agreement (the “Credit Agreement”) with a group of lenders. The Credit Agreement includes a $25,000 Revolving Credit Facility (the "Revolving Credit Facility") and a $90,000 Delayed Draw Term Loan Facility (“DDTL”), which are collectively referred to as the “Credit Facilities.” The proceeds from the Revolving Credit Facility can be used for general corporate purposes, whereas the proceeds from the DDTL were to be used solely to finance the acquisition of aircraft or engines to be registered in the United States. The Credit Agreement includes financial covenants that require a minimum trailing 12-month EBITDAR ($87,700 as of March 31, 2022 and beyond) and minimum liquidity of $30,000 at the close of any business day. The Company was in compliance with these covenants as of June 30, 2023.

During 2021, the Company drew $80,500 on the DDTL to purchase six aircraft, which were previously under operating leases. During 2022, the Company repaid the outstanding balance of the DDTL in full using proceeds received from the 2022-1 EETC, which terminated the DDTL. As a result, no amounts under the DDTL were available to the Company as of June 30, 2023. The Company recorded a $1,557 loss on extinguishment of debt in 2022 in connection with the repayment of the DDTL, which represents the write-off of the unamortized deferred financing costs. As of June 30, 2023, the Company had $24,650 of financing available through the Revolving Credit Facility, as $350 had been pledged to support a letter of credit.

Long-term Debt

Term Loan Credit Facility

During the six months ended June 30, 2023, the Company executed a term loan credit facility with a face amount of $119,200 for the purpose of financing the five Aircraft Held for Operating Lease. The loan is to be repaid monthly over 7 years. During the lease term, payments collected from the lessee will be applied directly to the repayment of principal and interest on the term loan credit facility. The Aircraft Held for Operating Lease, as well as the related lease payments received from the lessee, are pledged as collateral. During the six months ended June 30, 2023, the Company recorded $1,820 in debt issuance costs associated with the term loan credit facility.

The interest rate on the term loan credit facility is determined by using a base rate, which resets monthly, plus an applicable margin, and a fixed credit spread adjustment of 0.1%. The applicable margin during the lease term is fixed at 3.75%, and is subsequently reduced to 3.25% once the aircraft have been redelivered to the Company and a Loan-to-Value ("LTV") ratio calculation is completed at the end of the lease term. The interest rate in effect as of June 30, 2023 on the term loan was 8.9%. To the extent that the LTV exceeds 75% at the end of the lease term, a principal prepayment will be required in order to reduce the ratio to 75%. Amounts received under the end of lease maintenance compensation clause may be applied towards the LTV payment.

Pass-Through Trust Certificates

During March 2022, the Company arranged for the issuance of the 2022-1 EETC in an aggregate face amount of $188,277 for the purpose of financing or refinancing 13 aircraft. The Company is required to make bi-annual principal and interest payments each March and September, through March 2031. These notes bear interest at an annual rate between 4.84% and 5.75%. The weighted average interest rate was 5.06% as of June 30, 2023.

In December 2019, the Company arranged for the issuance of Class A, Class B and Class C trust certificates Series 2019-1 (the “2019-1 EETC”), in an aggregate face amount of $248,587 for the purpose of financing or refinancing 13 used aircraft, which was completed in 2020. The Company is required to make bi-annual principal and interest payments each June and December, through December 2027. These notes bear interest at an annual rate between 4.13% and 6.95%. The weighted average interest rate was 4.69% as of June 30, 2023.

Total as of June 30, 2023	$	453,109	$	(4,694)	$	448,415

The fair value of Debt was $425,031 as of June 30, 2023 and $324,059 as of December 31, 2022. The fair value of the Company’s debt was based on the discounted amount of future cash flows using the Company’s end-of-period estimated incremental borrowing rate for similar obligations. The estimates were primarily based on Level 3 inputs.

As of June 30, 2023, substantially all of the Company's investments have been in a continuous unrealized loss position for less than 12 months. The unrealized losses were the result of increases in market interest rates and were not the result of a deterioration in the credit quality of the securities. As of June 30, 2023, the Company believes that any unrealized losses are recoverable prior to the investment's conversion to cash. Therefore, the Company believes these losses to be temporary and no impairments have been recognized.

The effective tax rate for the three and six months ended June 30, 2022 was 19.0% and 118.1%, respectively. The effective tax rate represents a blend of federal and state taxes and includes the impact of certain nondeductible or nontaxable items.

Tax Receivable Agreement

The TRA balance as of June 30, 2023 and December 31, 2022 was $101,020 and $103,800, respectively. The TRA liability is an estimate and actual amounts payable under the Tax Receivable Agreement could differ from this estimate. During the six months ended June 30, 2023, the Company recorded an immaterial adjustment to the estimated TRA liability. During the six months ended June 30, 2022, the Company recorded an $8,500 adjustment to increase the estimated TRA liability.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

The Company has contractual obligations and commitments primarily with regard to lease arrangements, repayment of debt (see Note 6), payments under the TRA (see Note 10), and probable future purchases of aircraft.

As of June 30, 2023, the Company had a commitment to lease three aircraft with deliveries spanning the fourth quarter of 2023 and the first quarter of 2024. The leases will each have annual lease payments of approximately $2,000 for six years.

During the twelve months ended June 30, 2022, the compensation payable to an executive officer temporarily exceeded the restrictions on the payment of certain executive compensation under the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). Once the issue was identified, the executive officer voluntarily rescinded the unvested portion of the equity grant that caused the executive’s compensation to exceed the CARES Act limit. At no point did the executive's cash compensation and equity awards that could be monetized exceed the CARES Act limit. The Company did not accrue any amounts related to this matter as of June 30, 2023. To the extent we are deemed to have failed to remain in full

compliance with the CARES Act and the applicable rules and regulations thereunder, we may become subject to fines or other enforcement actions.

The Company is subject to various legal proceedings in the normal course of business and expenses legal costs as incurred. Management does not believe these proceedings will have a materially adverse effect on the Company.

BASIS OF PRESENTATION (Policies)

6 Months Ended

Jun. 30, 2023

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation

The Company has prepared the unaudited Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (“GAAP”) and has included the accounts of Sun Country Airlines Holdings, Inc. and its subsidiaries. Certain information and footnote disclosures normally included in the audited annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") for Form 10-Q. Therefore, the accompanying Condensed Consolidated Financial Statements of Sun Country Airlines Holdings, Inc. should be read in conjunction with the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the SEC ("2022 10-K"). Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited Condensed Consolidated Financial Statements for the interim periods presented. All material intercompany balances and transactions have been eliminated in consolidation.

Estimates and Assumptions

The preparation of financial statements in accordance with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Aircraft Held for Operating Lease, Maintenance Rights Asset, and Over-Market Asset

Aircraft Held for Operating Lease

The Company obtained outright ownership of the Aircraft Held for Operating Lease upon purchase and assumed the position of lessor until the end of the lease terms. The Company is entitled to fixed payments over the remaining lease term for each aircraft, which expire at various dates between the fourth quarter of 2024 and the fourth quarter of 2025. On each lease expiry date, the Aircraft Held for Operating Lease will be redelivered to Sun Country and are expected to be inducted into the Company’s fleet. The rental revenue associated with the Aircraft Held for Operating Lease is recognized as it is earned and is included in Other revenue. The Company has recognized $5,871 of rental revenue during the six months ended June 30, 2023.

Maintenance Rights Asset

Upon purchase of the Aircraft Held for Operating Lease, the Company recognized a Maintenance Rights Asset which represents the Company’s contractual right to receive the aircraft in a specified maintenance condition at the end of the lease. The acquired leases contain an end of lease compensation clause whereby the lessee is required to remit a cash payment to true-up the aircraft’s maintenance condition to full-life or perform the maintenance tasks needed to physically restore the airframe and engines to such a condition. The asset represents the difference between the Aircraft Held for Operating Lease’s physical maintenance condition as of the purchase date and the contractual return condition at the end of the lease term. The Maintenance Rights Asset is not depreciated over the lease term, nor will it accrete as additional life is consumed on the aircraft.

Over-Market Asset

Upon purchase of the Aircraft Held for Operating Lease, the Company recognized an intangible asset representing lease terms which are favorable to the lessor (unfavorable to the lessee), as compared with market terms of similar leases. The asset will be amortized over the remaining lease terms for the respective aircraft, which range from 1.4-2.4 years as of June 30, 2023. The amortization will be recognized as contra-revenue, offsetting the rental revenue associated with the Aircraft Held for Operating Lease included in Other revenue.
