Headquartered in Phoenix, Arizona, Mesa Air Group, Inc. ("Mesa" or the "Company") is the holding company of Mesa Airlines, Inc. ("Mesa Airlines"), a regional air carrier providing scheduled flight service to ~~116~~121 cities in 3641 states, the District of Columbia, the Bahamas, and Mexico as well as cargo flight services out of Cincinnati/Northern Kentucky International Airport. As of June 30, ~~2021, Mesa~~2022, Mesa’s fleet consisted of 168 aircraft which were operated under the Company’s Capacity Purchase Agreements (“CPAs”) and Flight Services Agreement (“FSA”), leased to a third party, held for sale or maintained as operational spares, ~~a fleet of 155 aircraft~~ with approximately ~~470~~360 daily departures and ~~3,191~~2,600 employees. ~~Mesa also leases 12 aircraft to a third party.~~ Mesa operates all of its flights ~~on behalf of major partners~~ as either American Eagle, United Express, or DHL Express flights pursuant to the terms of ~~Capacity Purchase Agreements (“CPAs”)~~CPAs entered into with American Airlines, Inc. (“American”) and United Airlines, Inc. (“United”) and ~~a Flight Services Agreement (“FSA”)~~FSA with DHL Network Operations (USA), Inc. (“DHL”) (each, our “major partner”).

The ~~financial arrangements~~CPAs between ~~the Company~~us and ~~its~~our major partners involve a revenue-guarantee arrangement whereby the major ~~partner pays~~partners pay fixed-fees for each aircraft under contract, departure, flight hour (measured from takeoff to landing, excluding taxi time) or block hour (measured from takeoff to landing, including taxi time), and reimbursement of certain direct operating expenses in exchange for providing flight services. The major partners also pay certain expenses directly to suppliers, such as fuel, ground operations and landing fees. Under the terms of these ~~capacity purchase agreements,~~CPAs, the major ~~partner controls~~partners control route selection, pricing, and seat inventories, reducing ~~the Company's~~our exposure to fluctuations in passenger traffic, fare levels, and fuel prices. Under our FSA with DHL, we receive a fee per block hour with a minimum block hour guarantee in exchange for providing cargo flight services. Ground support expenses including fueling and airport fees are paid directly by DHL.

The length and severity of the pilot shortage, which has impacted the US passenger and cargo carriers, remains uncertain. One of the primary factors contributing to the pilot shortage is the demand for pilots at major carriers, which are hiring at an accelerated rate to backfill the thousands of pilots whom they offered early retirements to at the beginning of the pandemic. These airlines now seek to increase their capacity to meet the growing demand for air travel as the global pandemic has moderated. A primary source of pilots for the major US passenger and cargo carriers are the US regional airlines.

While there is strong demand for air travel now in the United States, the exact timing and pace of a full recovery in demand remains uncertain given the significant impact of the pandemic on the overall U.S. and global economy. Air travel demand may continue to fluctuate as a result of the pandemic either moderating or becoming more extreme.

Our forecasted expenses and liquidity measures may be modified as we clarify the pilot shortage recovery timing and its impact upon our block hour production. The variable revenue based on the number of block hours has been significantly impacted by pilot attrition and our corresponding shortage of trained pilots. We may experience further reductions in subsequent quarters.

As a result of the pilot shortage, elevated pilot attrition and its negative impact on our financial results, we have taken, and are continuing to take, certain actions to increase liquidity and strengthen our financial position which include:

While there is no guarantee that these initiatives will come to fruition or otherwise achieve their desired objective, we believe it is probable that the initiatives outlined above, along with the cash flow from operating activities and cash on hand will provide us with adequate cash resources to maintain our operations and comply with our various debt and other contractual agreements, through at least the next 12 months.

As of June 30, 2022, the Company has $112.8 million of principal maturity payments on long-term debt due within the next twelve months. We plan to meet these obligations with our cash on hand, ongoing cashflows from our operations, as well as the liquidity created from our plans to monetize 18 CRJ-700 aircraft, refinance our revolving credit facility, and further amend our CPAs. If our plans are not realized, this will necessitate exploring additional opportunities to create liquidity by refinancing and deferring repayment of our principal maturity payments that are due within the next twelve months. The Company continues to monitor covenant compliance with its lenders as any noncompliance could have a material impact on the Company’s financial position, cash flows and results of operations. See Sources and Uses of Cash in our Management’s Discussion and Analysis of Financial Condition and Results of Operations section for additional disclosure.

As of June 30, ~~2021, the Company~~2022, we operated 4540 CRJ-900 aircraft under ~~the American~~an Amended and Restated Capacity Purchase Agreement ~~(the~~with American dated November 19, 2020 (as amended, the “American CPA”). In exchange for providing passenger flight services, we receive a fixed monthly minimum amount per aircraft under contract plus certain additional amounts based upon the number of flights and block hours flown during each month. In addition, we may also receive incentives or incur penalties based upon our operational performance, including controllable on-time ~~departures~~departure (“CD0”) and controllable flight completion (“CCF”) percentages. American also reimburses us for certain costs on an actual basis, including passenger liability and hull insurance and aircraft property taxes. Other expenses, including fuel and certain landing fees, are directly paid to suppliers by American. In addition, American also provides, at no cost to us, certain ground handling and customer service functions as well as airport-related facilities and gates at American hubs and cities where we operate.

~~On November 19, 2020, we entered into an Amended and Restated~~ The American Capacity Purchase Agreement (the “Amended and Restated American Capacity Purchase Agreement”) which was effective as of January 1, 2021 and amended and restated the Code Share and Revenue Sharing Agreement dated as of March 20, 2001 (as amended, supplemented and modified, the “Existing CPA”), between Mesa Airlines and American. The Amended and Restated American Capacity Purchase Agreement included the following amendments to the Existing CPA:

OnCPA expires on December ~~22, 2020, we entered into Amendment No. 1 (“Amendment No. 1”) to the Amended and Restated American Capacity Purchase Agreement. The amendments in Amendment No. 1 reflect the following:~~

~~On April 9, 2021, we entered into Amendment No. 2 (“Amendment No. 2”) to the Amended and Restated American Capacity Purchase Agreement. The amendments in Amendment No. 2 reflect the following:~~

On August 9, 2021, we entered into Amendment No. 5 (“Amendment No. 5”) to the Amended and Restated American Capacity Purchase Agreement. The amendments in Amendment No. 5 reflect the following:

Our ~~Amended and Restated~~ American ~~Capacity Purchase Agreement~~CPA is subject to termination prior to its expiration ~~subject to the Company’s right to cure,~~ in various circumstances including:

~~Our~~ ~~Amended~~Under the American CPA, American had the option in its sole discretion to withdraw up to: (i) ten (10) aircraft during calendar year 2021, (ii) 5 (5) aircraft during each of calendar years 2022 and ~~Restated~~2023, and (iii) during the period from January 1, 2024 to July 31, 2024, American ~~Capacity Purchase Agreement is~~can remove the first 20 aircraft to the extent not otherwise removed in 2021 – 2023, and thereafter American has the right to remove the remaining 20 aircraft. American also ~~subject to withdrawal rights, providing American with~~has the right and option to withdraw 1a specified number of aircraft upon each occurrence of the following:

On June 10, 2022, we amended our American CPA, pursuant to Amendment No. 8 thereto, to modify certain commercial terms thereunder. On June 20, 2022, we amended our American CPA, pursuant to Amendment No. 9 thereto, which amended and restated Schedule 1 (Covered Aircraft) to the American CPA and set forth certain equipment modification requirements with respect to Covered Aircraft added to such Schedule.

For the months of May and June 2022, we did not meet the CCF or CD0 minimum performance levels under the American CPA. The failure to meet the CCF or CD0 minimum performance levels for two (2) consecutive months under the terms of the American CPA gives American the right to remove two (2) additional aircraft from the CPA, one (1) aircraft for not meeting the CCF minimum performance level for two (2) consecutive months and one (1) aircraft for not meeting the CD0 minimum performance level for two (2) consecutive months. The Company's failure to meet the CCF or CD0 minimum performance levels for three (3) consecutive months gives American the right to terminate the CPA upon 90 days' notice and to provide a wind-down schedule. Subsequent to June 30, 2022, we entered into Amendment No. 10 to our American CPA which, among other things, reset the CCF and CD0 3-month measurement periods for purposes of American's termination rights to commence August 2022. See Note 17 - Subsequent Events for a discussion of Amendment No. 10. In addition to the foregoing, our block hour utilization has fallen below required levels in prior months, which also gives American the right to withdraw certain aircraft, subject to complying with applicable notice requirements under the American CPA. As of the date of this Quarterly Report on Form 10-Q, American has not exercised such withdrawal rights.

As of June 30, ~~2021,~~2022, we operated 60 E-175 and 20 E-175LL aircraft ~~for United~~ under ~~the United~~a Second Amended and Restated Capacity Purchase Agreement ~~(the~~with United dated November 4, 2020 (as amended, the “United CPA”). In exchange for providing ~~the~~passenger flight services, ~~under our United CPA,~~ we receive a fixed monthly minimum amount per aircraft under contract plus certain additional amounts based upon the number of flights and block hours flown and the results of passenger satisfaction surveys. United ~~also~~ reimburses us for certain costs on an actual basis, including property tax per aircraft and passenger liability insurance. ~~Other expenses, including fuel and certain landing fees, are directly paid to suppliers by United.~~

~~Under our~~ United ~~CPA, United owns 42 of the 60 E-175 and all of the E-175LL aircraft and leases them to us at nominal amounts. United~~also reimburses us on a pass-through basis for all costs related to heavy airframe and engine maintenance, landing gear, auxiliary power units ("APUs"), and component maintenance for the E-175 aircraft owned by United. Other expenses, including fuel and certain landing fees, are directly paid to suppliers by United.

Under our United CPA, United owns 42 of the 60 E-175 aircraft and all of the E-175LL aircraft and leases them to us at nominal amounts. The E-175 aircraft owned by United and leased to us have terms expiring between 2024 and 2028, and the 18 E-175 aircraft owned ~~E-175~~by us have terms expiring in 2028. The E-175LL aircraft have terms expiring between 2032 and 2033.

Pursuant to the United CPA, we agreed to lease our CRJ-700 aircraft to another United Express service provider for a term of nine (9) years. We ceased operating our CRJ-700 fleet in February 2021 in connection with the transfer of those aircraft into a lease agreement, and as of June 30, 2022, have entered into agreements to lease 20 of our 20 CRJ-700 aircraft.

~~On November 26, 2019, we amended and restated our United CPA. The Amended and Restated~~Our United CPA ~~included the following amendments:~~is subject to termination rights prior to its expiration in various circumstances including:

~~On November 4, 2020, we amended and restated our United CPA. The amendments reflect the following:~~

Our DHL ~~Flight Services Agreement~~FSA is subject to ~~following~~ termination rights prior to its ~~expiration:~~expiration in various circumstances including:

For the months of April, May, and June 2022, we did not meet the CCF and CA minimum performance levels under the DHL FSA. The failure to meet the minimum performance levels for three (3) consecutive months under the terms of the DHL FSA gives DHL the right to terminate the FSA. Management has received a waiver arising out of the failure to meet the aforementioned CCF and CA performance levels.

The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") and include the accounts of the Company and its wholly owned operating subsidiaries. Any reference in these notes to applicable guidance is meant to refer to the authoritative ~~United States generally accepted accounting principles~~GAAP as found in the Accounting Standards Codification ("ASC") and Accounting Standards Update ("ASU") of the Financial Accounting Standards Board ("FASB"). All intercompany accounts and transactions have been eliminated in consolidation. Reclassifications of certain immaterial prior period amounts have been made to conform to the current period presentation.

These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto as of and for the year ended September 30, ~~2020~~2021 included in the Company's Annual Report on Form 10-K for the year ended September 30, ~~2020~~2021 on file with the U.S. Securities and Exchange Commission (the "SEC"). Information and footnote disclosures normally included in financial statements have been condensed or omitted in these condensed consolidated financial statements pursuant to the rules and regulations of the SEC and GAAP. These condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented.

The Company is an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act") and may remain an emerging growth company until the last day of its fiscal year following the fifth anniversary of the Company’s initial public offering (“IPO”), subject to specified conditions. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. The Company has elected to "opt out" of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

As of June 30, ~~2021,~~2022, our chief operating decision maker was the Chief Executive Officer. While ~~the Company operates~~we operate under two separate capacity purchase agreements and a flight services agreement, we do not manage our business based on any performance measure at the individual contract level. Our chief operating decision maker uses consolidated financial information to evaluate our performance and allocate resources, which is the same basis on which he communicates our results and performance to our Board of Directors. Accordingly, we have a single operating and reportable segment.

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

~~The Company recognizes~~We recognize contract revenue when the service is provided under ~~its capacity purchase agreements~~our CPAs and ~~flight services agreement.~~FSA. Under the ~~capacity purchase agreements~~CPAs and ~~flight services agreement,~~FSA, our major partners generally pay for each departure, flight hour or block hour incurred, and an amount per aircraft in service each month with additional incentives or penalties based on flight completion, on-time performance, and other operating metrics. ~~The Company’s~~Our performance obligation is met as each flight is completed, and revenue is recognized and reflected in contract revenue.

~~Contract~~We recognize pass-through revenue ~~also includes temporary rate reductions~~when the service is provided under our ~~capacity purchase~~CPAs and FSA. Pass-through revenue represents reimbursements for certain direct expenses incurred including passenger liability and hull insurance, property taxes, other direct costs defined within the agreements, ~~impacting the period~~and major maintenance on aircraft leased from ~~December 2020 to September 2021. The basis for the reductions is temporary improvements in our cost structure being passed onto~~ our major partners ~~primarily from lower labor costs due to~~at nominal rates. Our performance obligation is met when each flight is completed or as the ~~grants received under the Payroll Support Program Extensions (PSP2~~maintenance services are performed, and ~~PSP3).~~revenue is recognized and reflected in pass-through and other revenue.

We record deferred revenue when cash payments are received or are due from our major partners in advance of our performance. During the three and nine months ended June 30, 2022, we recognized $6.8 million and $11.8 million of previously deferred revenue, respectively. Deferred revenue is recognized as flights are completed over the remaining terms of the respective contracts.

The deferred revenue balance as of June 30, 2022 represents our aggregate remaining performance obligations that will be recognized as revenue over the period in which the performance obligations are satisfied, and is expected to be recognized as revenue as follows (in thousands):

A portion of ~~the Company's~~our compensation under ~~its capacity purchase agreements~~our CPAs with American and United is designed to reimburse the Company for certain aircraft ownership costs. Such costs include aircraft principal and interest debt service costs, aircraft depreciation, and interest expense or aircraft lease expense costs while the aircraft is under contract. ~~The Company has~~We have concluded ~~that a~~this component of ~~its revenue~~the compensation under these agreements is ~~deemed to be~~ lease revenue, as such agreements identify the "right of use" of a specific type and number of aircraft over a stated ~~period-of-time.~~ period of time. We account for the non-lease component under ASC 606 and account for the lease component under ASC 842. We allocate the consideration in the contract between the lease and non-lease components based on their stated contract prices, which is based on a cost basis approach representing our estimate of the stand-alone selling prices.

The lease revenue associated with ~~the Company's capacity purchase agreements~~our CPAs is accounted for as an operating lease and is reflected as contract revenue onin the ~~Company's~~condensed consolidated statements of ~~operations. The Company~~operations and comprehensive income (loss). We recognized ~~$41.2~~$38.7 million and ~~$52.0~~$41.2 million of lease revenue for the three months ended June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, and ~~$131.8~~$118.5 million and ~~$157.7~~$131.8 million during the nine months ended June 30, 2022 and 2021, ~~and 2020, respectively~~. ~~The Company has~~respectively. We have not separately stated aircraft rental income ~~and aircraft rental expense~~ in the condensed consolidated statements of operations and comprehensive income (loss) because the use of the aircraft is not a separate activity from the total service provided under our ~~capacity purchase agreements.~~CPAs.

The Company recognizes pass-through revenue when the service is provided under its capacity purchase agreements and flight services agreement. Pass-through revenue represents reimbursements for certain direct expenses incurred including ~~passenger liability and hull insurance,~~ property taxes, other direct costs defined within the capacity purchase agreements, and major maintenance on aircraft leased at nominal rates. The Company’s performance obligation is met when each flight is completed or as the maintenance services are performed, and revenue is recognized and reflected in pass-through and other revenue.

~~The Company~~We have entered into lease agreements with GoJet Airlines LLC (“GoJet”) to lease 1220 CRJ-700 aircraft as of June ~~2021.~~30, 2022. The lease agreements are accounted for as operating leases and have a term of nine (9) years beginning on the delivery date of each aircraft. Under the lease agreements, GoJet pays fixed monthly rent per aircraft and variable lease payments for supplemental rent based on monthly aircraft utilization at fixed rates. Supplemental rent payments are subject to reimbursement following GoJet’s completion of qualifying maintenance events defined in the agreements. Lease revenue for fixed monthly rent payments is recognized ratably within contract revenue. Lease revenue for supplemental rent is deferred and recognized within contract revenue when it is probable that amounts received will not be reimbursed for future qualifying maintenance events over the lease term.

~~The Company mitigates~~We mitigate the residual asset risks through supplemental rent payments and by leasing aircraft and engine types that we can ~~be operated by the Company~~operate in the event of a default. Additionally, the ~~operating~~ leases have specified lease return condition requirements and ~~the Company maintains~~we maintain inspection rights under the leases. As of June 30, ~~2021, the Company~~2022, we recognized ~~$10.1~~$15.0 million of lease incentive assets, net of amortization, and ~~$8.8~~$11.6 million of related lease incentive obligations for reimbursement of certain aircraft maintenance costs defined within the lease agreements. Lease incentive assets are amortized on a straight-line basis and recognized as a reduction to lease revenue over the lease term.

Lease revenue recognized under the GoJet agreements, net of amortization of the lease incentive assets, was $7.1 million and $20.3 million for the three and nine months ended June 30, 2022, respectively, and $3.4 million and $4.0 million for the three and nine months ended June 30, 2021, respectively. Amounts deferred for supplemental rent payments totaled ~~$0.2~~$2.6 million as of June 30, ~~2021.~~ 2022.

The following table summarizes future minimum rental income under operating leases related to leased aircraft that had remaining non-cancelable lease terms as of June 30, ~~2021~~2022 (in thousands):

We determine if an arrangement is a lease at inception. As a lessee, we have lease agreements with lease and non-lease components and have elected to account for such components as a single lease component. Our operating lease activities are recorded in operating lease right-of-use assets, current maturities of operating leases, and noncurrent operating lease liabilities in the condensed consolidated balance sheets. Finance leases are reflected in property and equipment, net, current portion of long-term debt and finance leases, and long-term debt and finance leases, excluding current portion in the condensed consolidated balance sheets.

Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Certain variable lease payments are ~~received or are due from our major partners~~not included in ~~advance~~the calculation of the ~~Company’s performance, including amounts~~right-of-use assets and lease liability due to uncertainty of the payment amount and are recorded as lease expense in the period incurred. In determining the present value of lease payments, we use either the implicit rate in the lease when it is readily determinable or our estimated incremental borrowing rate, based on information available at the lease commencement. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Operating lease costs are ~~refundable. During the three and nine months ended June 30, 2021, the Company deferred $1.9 million and $12.0 million of revenue, respectively, which was billed and paid by our major partners.~~

~~The deferred revenue balance as of June 30, 2021 represents our aggregate remaining performance obligations that will be~~ recognized ~~as revenue~~on a straight-line basis over the ~~period~~lease term, while finance leases result in ~~which~~a front-loaded expense pattern.

As a lessee, we have elected a short-term lease practical expedient on all classes of underlying assets, permitting us to not apply the ~~performance obligations are satisfied, and is expected~~recognition requirements of ASC 842 to ~~be recognized as revenue as follows (in thousands):~~leases with terms of 12 months or less.

~~As discussed in Note 1, we~~We lease, at nominal rates, certain aircraft from United and DHL under our United ~~Capacity Purchase Agreement~~CPA and DHL ~~Flight Services Agreement,~~FSA, which are excluded from operating lease assets and liabilities as ~~the lease contracts~~they do not represent embedded leases under ASC 842. Other than such leases at nominal ~~leases with our major partners,~~amounts, approximately ~~10%~~11% of our aircraft are leased from third parties. All of our aircraft leases have been classified as operating leases, which results in rental payments being charged to expense over the term of the related leases. In the event that we or one of our major partners decide to exit an activity involving leased aircraft, losses may be incurred. In the event that we exit an activity that results in exit losses, these losses are accrued as each aircraft is removed from operations for early termination penalties, lease settle up and other charges. Additionally, any remaining ROU assets and lease liabilities ~~would be~~are written off.

The majority of ~~the Company's~~our leased aircraft are leased through trusts that have a sole purpose to purchase, finance, and lease these aircraft to ~~the Company;~~us; therefore, they meet the criteria of a variable interest entity. However, since these are single-owner trusts in which ~~the Company does~~we do not participate, ~~the Company is~~we are not at risk for losses and isare not considered the primary beneficiary. Management believes that ~~the Company's~~our maximum exposure under these leases is the remaining lease payments.

Contract liabilities consist of deferred credits for cost reimbursements from major partners related to aircraft modifications and ~~employee~~pilot training associated with capacity purchase agreements. The deferred credits are recognized over time depicting the pattern of the transfer of control of services resulting in ratable recognition of revenue over the remaining term of the capacity purchase agreements.

Current and non-current deferred credits are recorded toin other accrued expenses and non-current deferred credits in the condensed consolidated balance sheets. ~~The Company's~~Our total current and non-current deferred credit ~~contract liability~~ balances at June 30, ~~2021~~2022 and September 30, ~~2020 are $5.0~~2021 were $4.1 million and ~~$8.5~~$4.8 million, respectively. ~~The Company~~We recognized $0.2 million and ~~$0.9~~$0.2 million of the

deferred credits within contract revenue during the three months ended June 30, 2022 and 2021, ~~and 2020,~~ respectively, and ~~$2.1~~$0.6 million and ~~$2.9~~$2.1 million during the nine months ended June 30, 2022 and 2021, ~~and 2020,~~ respectively.

~~The Company operates~~We operate under ~~a Federal Aviation Administration (“FAA”)~~an FAA approved continuous inspection and maintenance program. The cost of non-major scheduled inspections and repairs and routine maintenance costs for all aircraft and engines are charged to maintenance expense as incurred.

~~The Company accounts~~We account for heavy maintenance and major overhaul costs on ~~its~~our owned E-175 fleet under the deferral method whereby the cost of heavy maintenance and major overhaul is deferred and amortized until the earlier of the end of the useful life of the related asset or the next scheduled heavy maintenance event. Amortization of heavy maintenance and major overhaul costs charged to depreciation and amortization expense was $0.5 million and $0.1 million for the three months ended June 30, 2022 and 2021, respectively, and $1.2 million and $0.1 million for the nine months ended June 30, 2022 and 2021, ~~and 2020. At~~respectively. As of June 30, ~~2021~~2022 and September 30, ~~2020, the Company had a~~2021, our deferred heavy maintenance balance, net of accumulated amortization, ~~of $2.8~~was $6.8 million and ~~$0.0~~$3.5 million, respectively.

~~The Company accounts~~We account for heavy maintenance and major overhaul costs for all other fleets under the direct expense method whereby costs are expensed to maintenance expense as incurred, except for certain maintenance contracts where labor and materials price risks have been transferred to the service provider and require payment on a utilization basis, such as flight hours. Costs incurred for maintenance and repair for utilization maintenance contracts where labor and materials price risks have been transferred to the service provider are charged to maintenance expense based on contractual payment terms.

Engine overhaul expense totaled ~~$4.0~~$8.1 million and ~~$3.2~~$4.0 million for the three months ended June 30, ~~2021,~~2022 and ~~2020,~~2021, respectively, of which ~~$2.7~~$6.0 million and ~~$0.4~~$2.7 million, respectively, was pass-through expense. Engine overhaul expense totaled ~~$25.3~~$18.2 million and ~~$28.3~~$25.3 million for the nine months ended June 30, ~~2021,~~2022 and ~~2020,~~2021, respectively, of which $14.5 million and ~~$3.0~~$14.5 million, respectively, was pass-through expense. Airframe C-check expense totaled ~~$14.1~~$5.0 million and ~~$2.9~~$14.1 million for the three months ended June 30, ~~2021,~~2022 and ~~2020,~~2021, respectively, of which ~~$5.6~~$1.3 million and ~~$0.8~~$5.6 million, respectively, was pass-through expense.

~~In February 2021,~~We classify assets as held for sale when our management approves and commits to a formal plan of sale that is probable of being completed within one year. Assets designated as held for sale are recorded at the ~~Company was granted $48.7 million~~lower of their current carrying value or their fair market value, less costs to sell, beginning in ~~financial assistance by~~ the ~~U.S. Department~~period in which the assets meet the criteria to be classified as held for sale. See Note 6 for further discussion of ~~the Treasury under the Payroll Support Program Extension (“PSP2”) under the Consolidated Appropriations Act of 2021. In March 2021~~, the Company was notified that, based on funding availability, recipients that were currently in compliance with executed PSP agreements would receive an additional award amount. As a result, the Company received an additional $7.3 million through PSP2 in April 2021our assets classified as held for a total grant of $56.0 million. PSP2 funding must be used exclusively for the continuation of payment of employee wages, salaries, and benefits and is conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs from the date of the extension agreement through March 2021. Other conditions include prohibitions on share repurchases and dividends through March 2022 and certain limitations on executive compensation until October 2022. The Department of Transportation also has the authority until March 1, 2022 to require airlines that received payroll support program funds to maintain scheduled air service deemed necessary to any point served by the airline before March 1, 2020.

On April 15, 2021, the Company was notified by the U.S. Department of the Treasury that it was eligible to receive funds under the third Payroll Support Program (“PSP3”), which was created under the American Recovery Plan Act of 2021 (“ARPA”), enacted on March 11, 2021. PSP3 provides additional funding for passenger air carriers and contractors that received financial assistance under PSP2. The funding must be used exclusively for the continuation of payment of employee wages, salaries, and benefits. The Company was granted $52.2 million and received the first PSP3 installment of $26.1 million in April 2021 and the second installment of $26.1 million in May 2021. These payments are conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs through September 2021 or the date on which assistance provided under the agreement is exhausted, whichever is later. Other conditions include prohibitions on share repurchases and dividends through September 2022 and certain limitations on executive compensation until April 2023.

During the three and nine months ended June 30, 2021, the Company recognized $26.1 million and $93.4 million, respectively, for the payroll support government funds. During the three and nine months ended June 30, 2020, the Company recognized $43.0 million for the payroll support government funds. Assale as of June 30, 2021, there are $26.1 million of deferred payments remaining under PSP3, which are recorded within other accrued liabilities in the condensed consolidated balance sheets and will be recognized as a reduction of operating expenses during the quarter ended September 30, 2021.2022.

In ~~June 2016,~~December 2019, the FASB issued ~~new guidance requiring all expected credit losses~~ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for ~~financial instruments held at~~Income Taxes (“ASU 2019-12”) to simplify the ~~reporting date to be measured based on historical experience, current conditions, and reasonable supportable forecasts. This replaces~~accounting for income taxes by eliminating certain exceptions allowable under the existing ~~incurred loss model and is applicable~~guidance related to the ~~measurement~~approach for intraperiod tax allocations, the methodology for calculating income taxes in an interim period, and the recognition of ~~credit losses on financial instruments measured at amortized cost and also applies to some off-balance sheet credit exposures.~~deferred tax liabilities for outside basis differences. Our adoption of this guidance on ~~a modified retrospective basis on~~ October 1, ~~2020~~2021 did not have a material ~~impact as credit losses have not been, and are not expected to be, significant based on historical collection trends, the financial condition of our major partners and external market factors.~~

In August 2018, the FASB issued new guidance aligning the accounting for implementation costs incurred in cloud computing arrangements with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted this guidance on a prospective basis on October 1, 2020. Amounts capitalized are immaterial.

In December 2019, the FASB issued new guidance to simplify the accounting for income taxes. The guidance is effective for annual and interim reporting periods beginning after December 15, 2020, and interim periods within those fiscal periods. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”). This ASU provides optional expedients and exceptions for a limited period of time for accounting for contracts, hedging relationships, and other transactions affected by the ~~market transition from the~~ London Interbank Offered Rate (LIBOR) or ~~other~~another reference ~~rates~~rate expected to be discontinued. Optional expedients can be applied ~~from March 12, 2020~~ through December 31, 2022. We ~~are currently evaluating the impact~~continue to evaluate our contracts that ~~the new guidance will have on our consolidated financial statements.~~reference LIBOR.

Financial instruments that potentially expose the Company to a concentration of credit risk consist principally of cash and cash equivalents that are primarily held by financial institutions in the United States and accounts receivable. Amounts on deposit with a financial institution may at times exceed federally insured limits. ~~The Company maintains its~~We maintain our cash accounts with high credit quality financial institutions and, accordingly, minimal credit risk exists with respect to the financial institutions.

As of June 30, ~~2021, the Company~~2022, we had ~~$3.4~~$3.3 million in restricted cash. We have an agreement with a financial institution for a letter of credit facility and to issue letters of credit for particular airport authorities, worker's compensation insurance, property and casualty insurance and other business needs as required in certain lease agreements. Pursuant to the terms of this agreement, ~~$3.4~~$3.3 million of outstanding letters of credit are required to be collateralized by amounts on deposit.

Significant customers are those which represent more than 10% of ~~the Company’s~~our total revenue or net accounts receivable balance at each respective balance sheet date. ~~At June 30, 2021, the Company had capacity purchase agreements with American and United and a flight services agreement with DHL. Substantially all~~All of ~~the Company's condensed consolidated~~our revenue for the three and nine months ended June 30, 2022 and 2021 was derived from the American and ~~2020~~United CPAs, DHL FSA, and from leases of our CRJ-700 aircraft to GoJet. Substantially all of our accounts receivable at June 30, 2022 and September 30, 2021 was derived from these agreements. ~~Substantially all of the Company’s accounts receivable at June 30, 2021 and September 30, 2020 was derived from these agreements.~~

American accounted for approximately 46% and 45% ~~and 60%~~ of ~~the Company's~~our total revenue for the three months ended June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, and ~~46 %~~46% and ~~53%~~46% of ~~the Company’s~~our total revenue for the nine months ended June 30, ~~2021~~2022 and ~~2020,~~2021, respectively.

A termination of either the American or ~~the~~ United ~~capacity purchase agreements~~CPA would have a material adverse effect on ~~the Company's~~our business prospects, financial condition, results of operations, and cash flows.

Periodically, ~~the Company's~~our major partners dispute amounts billed and pay amounts less than the amount billed. Ultimate collection of the remaining amounts not only depends upon the Company prevailing under the applicable audit, but also

upon the financial well-being of the major partner.

If ~~the Company's~~our ability to collect these receivables and the financial viability of ~~its~~our major partners is materially different than estimated, ~~the Company's~~our estimate of the allowance for credit losses could be materially impacted.

Information about ~~the~~our intangible assets ~~of the Company~~ as of June 30, ~~2021~~2022 and September 30, ~~2020,~~2021, is as follows (in thousands):

As of June 30, ~~2021, the Company’s~~2022, our intangible assets’ remaining ~~weighted average~~amortization term is ~~14.3~~13.3 years.

During 2022, our management committed to a formal plan to sell certain of our CRJ-900 and CRJ-200 aircraft. The aircraft are expected to be disposed of via sale within the next 12 months. Accordingly, we determined the aircraft met the criteria to be classified as assets held for sale and have separately presented them in our condensed consolidated balance sheet at the lower of their current carrying value or their fair market value less costs to sell. The fair values are based upon observable and unobservable inputs, including recent purchase offers and market trends and conditions. The assumptions used to determine the fair value of our assets held for sale are subject to inherent uncertainty and could produce a wide range of outcomes which we will continue to monitor in future periods as new information becomes available. Prior to the ultimate sale of the assets, subsequent changes in our estimate of the fair value of our assets held for sale will be recorded as a gain or loss with a corresponding adjustment to the assets’ carrying value. In connection with the classification of these assets as held for sale, we recorded impairment losses of $39.5 million, which are reflected within impairment of assets held for sale in our condensed consolidated statements of operations and comprehensive income (loss).

In connection with a negotiated forward purchase contract for electrically-powered vertical takeoff and landing aircraft (“eVTOL aircraft”) executed in February 2021, we obtained ~~equity warrant assets~~warrants giving us the right to acquire ~~1,171,649~~

a number shares of common stock in Archer Aviation, Inc. ~~(Archer),~~(“Archer”). We estimated the initial equity warrant asset value to be $16.4 million based on publicly available information as of the grant date. In September 2021, the merger between Archer and a ~~private, venture-backed company.~~ special purpose acquisition company (“SPAC”) was completed, resulting in a readily determinable fair value of our investments in Archer. Accordingly, gains and losses associated with changes in the fair value of our investments in Archer are measured in earnings, in accordance with ASC 321, Investments – Equity Securities. In connection with the closing of the merger between Archer and the SPAC, we purchased 500,000 Class A common shares in Archer for $5.0 million, and obtained an additional warrant to purchase shares of Archer with a total grant date value of $5.6 million. All of our vested warrants have been exercised into shares of Archer common stock.

The initial grant date values of the warrants were recognized as a vendor credit liability within other noncurrent liabilities. The liability related to the warrant assets will be settled in the future, as a reduction of the acquisition date value of the eVTOL aircraft contemplated in the related aircraft purchase agreement.

Our investments in Archer are classified as Level 1 within the fair value hierarchy as the values are determined using quoted prices for the equity securities.

In connection with a negotiated forward purchase contract for fully electric aircraft executed in July 2021, we obtained $5.0 million of preferred stock in Heart Aerospace Incorporated (“Heart”), a privately held company. Our investment in Heart does not have a readily determinable fair value, so we account for the investment using the measurement alternative under ASC 321 and measure the investment at initial cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments from the same issuer. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, financing transactions subsequent to the acquisition of the investment, or other features that indicate a change to fair value is warranted. Any changes in fair value from the initial cost of the investment in preferred stock are recognized as increases or decreases on our balance sheet and as net gains or losses on investments in equity securities. The initial investment in preferred stock was measured at cost of $5.0 million.

In connection with a negotiated forward purchase contract for hybrid-electric vertical takeoff and landing (“VTOL”) aircraft executed in February 2022, we obtained a warrant giving us the right to acquire a number of shares of common stock in the privately-held manufacturer of the VTOL aircraft. These investments do not have a readily determinable fair value, so we account for them using the measurement alternative under ASC 321 and measure the investments at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments from the same issuer. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, financing transactions subsequent to the acquisition of the investment or other features that indicate a discount to fair value is warranted. Any changes in fair value from the grant date ~~fair~~ value of the ~~equity~~ warrant assets will be recognized as increases or decreases to the investment on our balance sheet and as net gains or losses on investments equity ~~warrant assets, in other (expense) income, net.~~securities. We estimated the initial ~~equity~~ warrant asset value to be ~~$16.4~~$3.2 million based on ~~publicly available information as~~prices of similar investments in the ~~grant date.

The liability related to the warrant assets will be settled in the future, as a reduction of the acquisition date value of the ~~eVTOL~~VTOL aircraft contemplated in the related ~~aircraft~~forward purchase agreement.

Total net losses on our investments in equity securities totaled $3.9 million and $12.6 million during the three and nine months ended June 30, 2022, respectively, and are reflected in loss on investments, net in our condensed consolidated statements of operations and comprehensive income (loss). As of June 30, 2022, the aggregate carrying amount of our investments in equity securities was $16.0 million, and the carrying amount of our investments without readily determinable fair values was $9.6 million.

Fair value is an exit price representing the amount that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Accounting standards include disclosure requirements relating to the fair values used for certain financial instruments and establish a fair value hierarchy. The hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of three levels:

Other than our assets held for sale and investments in equity securities described in Notes 6 and 7, respectively, we did not measure any of our assets or liabilities at fair value on a recurring or nonrecurring basis as of June 30, 2022 and September 30, 2021.

The carrying values reported in the condensed consolidated balance sheets for cash and cash equivalents, accounts receivable, and accounts payable approximate fair value because of the immediate or short-term maturity of these financial instruments.

~~The Company's~~Our debt agreements are not traded on an active market. ~~The Company has~~We have determined the estimated fair value of ~~its~~our debt to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable and, therefore, could be sensitive to changes in inputs. ~~The Company utilizes~~We utilize the discounted cash flow method to estimate the fair value of Level 3 debt.

The carrying value and estimated fair value of ~~the Company's~~our total long-term debt, including current maturities, were as follows (in millions):

The ~~net book~~carrying value of collateralized aircraft and equipment as of June 30, ~~2021~~2022 was ~~$1,044.1~~approximately $1,014.2 million.

In December 2015, an Enhanced Equipment Trust Certificate ("EETC") pass-through trust was created to issue pass-through certificates to obtain financing for new E-175 aircraft. AtAs of June 30, ~~2021, Mesa has $162.2~~2022, we had $141.7 million of equipment notes outstanding issued under the EETC financing included in long-term debt onin the condensed consolidated balance sheets.

The structure of the EETC financing consists of a pass-through trust created by Mesa to issue pass-through certificates, which represent fractional undivided interests in the pass-through trust and are not obligations of Mesa.

The proceeds of the issuance of the pass-through certificates were used to purchase equipment notes which were issued by Mesa and secured by its aircraft. The payment obligations under the equipment notes are those of Mesa. Proceeds received from the sale of pass-through certificates were initially held by a depositary in escrow for the benefit of the certificate holders until Mesa issued equipment notes to the trust, which purchased such notes with a portion of the escrowed funds.

~~Mesa~~We evaluated whether the pass-through trust formed for ~~its~~the EETC financing is a Variable Interest Entity ("VIE") and required to be consolidated. ~~The pass-through trust was~~We have determined ~~to be~~we do not have a ~~VIE; however, the Company has determined that it is not the primary beneficiary of~~variable interest in the pass-through trust, and therefore, ~~has~~we have not consolidated the pass-through trust with ~~its~~our financial statements.

On September 25, 2019, ~~the Company~~we extended the term on ~~its~~our $35.0 million working capital draw loan by three years, which now terminates in September 2022. Interest is assessed on drawn amounts at one-month LIBOR plus 3.75%. As of June 30, ~~2021, $22.9 million has been drawn~~2022, the amount outstanding on the ~~revolver.~~working capital draw loan was $15.6 million.

~~Future borrowings, if any, under~~Our CIT revolving credit facility includes a minimum interest and rental coverage ratio covenant. In March and April 2022, we entered into amendments to the CIT revolving credit facility which lowered the minimum interest and rental coverage ratio covenant for the December 2021, March 2022, and June 2022 quarters. As a result, we are in compliance with this covenant.

On June 30, 2022, we entered into the Second Amended and Restated Credit and Guaranty Agreement by and among Mesa Airlines and Mesa Air Group Airline Inventory Management, L.L.C., as borrowers, Mesa Air Group, as a Guarantor, the other guarantors party thereto from time to time, CIT Bank, as Administrative Agent, and the other lenders party thereto, which was effective as of June 30, 2022 and extended the maturity date of the facility ~~are subject~~by three (3) months to ~~among other things, the Company having sufficient unencumbered assets to meet the borrowing base requirements under the facility.~~December 31, 2022

On October 30, 2020, ~~the Company~~we entered into a ~~Loan~~loan and ~~Guarantee Agreement~~guarantee agreement with the U.S. Department of the Treasury (the “U.S. Treasury”) for a secured loan facility of up to $200.0 million that matures in October 2025 (“the Treasury Loan”). ~~On October 30, 2020,~~During the ~~Company borrowed $43.0 million and on November 13, 2020, the Company~~first quarter of fiscal 2021, we borrowed an ~~additional $152.0~~aggregate of $195.0 million. NaN further borrowings are available under the Treasury Loan. ~~The Company also issued warrants to purchase shares of common stock to the U.S. Treasury.~~

The Treasury Loan bears interest at a variable rate equal to (a)(i) the LIBOR rate divided by (ii) one minus the Eurodollar Reserve Percentage plus (b) 3.50%. Accrued interest on the loans ~~will be~~is payable in arrears, or paid-in-kind by increasing the principal balance of the loan by such interest payment, on the first business day following the 14^th day of each March, June, September, and ~~December, beginning with December 15, 2020.~~December.

All principal amounts outstanding under the Treasury Loan are due and payable in a single installment on October 30, ~~2025 (the “Maturity Date”). Interest will be paid~~2025. Through June 30, 2022, interest on the Treasury Loan has been paid-in-kind by increasing the principal amount of the loan by the amount of such interest due on anthe interest payment ~~date for~~date. Commencing in June 2022, we initiated the ~~first 12 months. Mesa's~~payment of interest in lieu of increasing the principal amount of the loan. Our obligations under the Treasury Loan are secured by certain aircraft, aircraft engines, accounts receivable, ground service equipment, flight simulators, and tooling (collectively, the “Collateral”). The obligations under the Treasury Loan are guaranteed by the Company and Mesa Air Group Inventory Management. The proceeds ~~may be~~were used for general corporate purposes and operating expenses, to the extent permitted by the ~~CARES Act.~~Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). Voluntary prepayments of ~~loans under~~ the Treasury Loan may be made, in whole or in part, ~~by Mesa Airlines,~~ without premium or penalty, at any time and from time to time. Amounts prepaid may not be reborrowed. Mandatory prepayments of ~~loans under~~ the Treasury Loan are required, without premium or penalty, to the extent necessary to comply with the covenants discussed below, certain dispositions of the Collateral, certain debt issuances secured by liens on the Collateral, and certain insurance payments related to the Collateral. In addition, if a “change of control” (as defined in the Treasury Loan) occurs with respect to Mesa Airlines, ~~Mesa Airlines~~we will be required to repay the loans outstanding under the Treasury Loan.

The Treasury Loan requires ~~the Company,~~us, under certain circumstances, including within ten (10) business days prior to the last business day of March and September of each year beginning March 2021, to appraise the value of the Collateral and recalculate the collateral coverage ratio. If the calculated collateral coverage ratio is less than 1.6 to 1.0, ~~Mesa Airlines will be~~we are required either to provide additional Collateral (which may include cash collateral) to secure ~~its~~the obligations under the Treasury Loan or repay the term loans under the Treasury Loan, in such amounts that the recalculated collateral coverage ratio, after giving effect to any such additional Collateral or repayment, is at least 1.6 to 1.0.

The Treasury Loan contains two financial covenants, a minimum collateral coverage ratio and a minimum liquidity level. The Treasury Loan also contains customary negative and affirmative covenants for credit facilities of this type, including, among others: (a) limitations on dividends and distributions; (b) limitations on the creation of certain liens;

(c) restrictions on certain dispositions, investments, and acquisitions; (d) limitations on transactions with affiliates; (e) restrictions on fundamental changes to the business, and (f) restrictions on lobbying activities. Additionally, ~~the Company is~~we are required to comply with the relevant provisions of the CARES Act, including limits on employment level reductions after September 30, 2020, restrictions on dividends and stock buybacks, limitations on executive compensation, and requirements to maintain certain levels of scheduled service.

In connection with the Treasury Loan ~~and Guarantee Agreement~~ and as partial compensation to the U.S. Treasury for the provision of financial assistance under the Treasury Loan, ~~and Guarantee Agreement, the Company~~we issued to the U.S. Treasury warrants to purchase an aggregate of 4,899,497 shares of ~~the Company’s~~our common stock at an exercise price of $3.98 per share, which was the closing price of the ~~Common Stock on The Nasdaq Stock Market~~common stock on April 9, 2020. The exercise price and number of shares of common stock issuable under the ~~Warrants~~warrants are subject to adjustment as a result of anti-dilution provisions contained in the ~~Warrants~~warrants for certain stock issuances, dividends, and other corporate actions. The warrants expire on the fifth anniversary of the date of issuance and are exercisable either through net share settlement or net cash settlement, at ~~the Company’s~~our option. ~~For accounting purposes, the~~The fair value ~~for~~of the ~~Treasury Loan Warrant Shares is~~warrants was estimated using a Black-Scholes option pricing model and recorded in stockholders' equity with an offsetting debt discount to the Treasury ~~Term~~ Loan ~~Facility~~ in the condensed consolidated balance ~~sheet.~~sheets.

~~The Company incurred $3.1 million in debt issuance costs relating to the Treasury Loan.~~ In ~~accordance~~April 2022, we entered into an agreement with the ~~applicable guidance, Mesa allocated~~U.S. Treasury to lower the ~~debt issuance costs between the Treasury Loan and related warrants. At funding on October~~minimum collateral coverage ratio covenant to 1.5 to 1.0 through September 30, ~~2020, the initial $43.0 million was recorded net~~2022. As a result, we are in compliance with this covenant as of ~~$0.7 million in capitalized debt issuance costs. At funding on November 13, 2020, the remaining $152.0 million was recorded net~~June 30, 2022.

In December 2021, we entered into a loan agreement with a financing institution to finance certain purchases of ~~$2.3 million in capitalized debt issuance costs. The remaining $0.1 million in debt issuance costs was allocated to the warrants as~~spare engines via a reduction to the warrant value within additional paid-in capital. Debt issuance costs allocated to the debt are amortized into interest expense using the effective interest method over the term of the related loan.

Prior to the November 13, 2020 funding of the $152.0 million portion of the Treasury Loan, the Company repaid $167.7 million in existing aircraft debt covering 44 aircraft, including indebtedness under its (a) Senior Loan Agreements, dated June 27, 2018, (b) Junior Loan Agreements, also dated June 27, 2018, (c) Credit Agreements, dated January 31, 2007, April 16, 2014, and May 23, 2014, (d) Senior Loan Agreements, dated December 27, 2017, and (e) Junior Loan Agreements, also dated December 27, 2017 (collectively, “the EDC Loans”newly formed limited liability company (“LLC”). The ~~Company made~~loan agreement provides for aggregate borrowings of up to $54.0 million through November 2022. In December 2021, we borrowed an aggregate of $35.3 million under the loan agreement, which matures in December 2027. The borrowed amounts are collateralized by the underlying engines and require monthly principal and interest payments ~~totaling $164.2 million~~until maturity. Borrowings under the loan agreement bear interest at the monthly LIBOR plus 4.25%. The borrowings are the obligation of the newly formed LLC and are guaranteed by Mesa Airlines, Inc.

The newly formed LLC, which is wholly owned by Mesa, was determined to ~~repay~~be a VIE for which we are the ~~EDC Loans, consisting~~primary beneficiary because we have the power to direct the activities of the LLC that most significantly impact the LLC’s economic performance and the obligation to absorb losses and right to receive benefits from the LLC in our capacity as sole member of the LLC and guarantor of the borrowings. Therefore, the LLC is consolidated in our financial statements and the borrowings are reflected as long-term debt in our condensed consolidated balance sheets.

The loan agreement contains a loan-to-value (“LTV”) financial covenant pursuant to which we are required to prepay certain amounts of the loan if the aggregate outstanding principal balance of ~~$167.7 million,~~the loan exceeds a specified percentage of the appraised value of the engines beginning in the 12^th full month after closing and ~~a $3.5 million discount on the balance owed.

Calculations of net income (loss) per common share attributable to Mesa Air Group were as follows (in thousands, except per share data):

Basic income or loss per common share is computed by dividing net income or loss attributable to Mesa Air Group by the weighted average number of common shares outstanding during the period.

The number of incremental shares from the assumed issuance of shares relating to restricted stock and exercise of warrants ~~(excluding warrants with a nominal conversion price)~~ is calculated by applying the treasury stock method. Share-based awards and warrants whose impact is anti-dilutive under the treasury stock method ~~were~~are excluded from the diluted net income or loss per share calculation. In loss periods, these incremental shares are excluded from the calculation of diluted loss per share, as the inclusion of unvested restricted stock and warrants would have an anti-dilutive effect. ~~There were 0 anti-dilutive~~

~~The Company previously issued warrants to third parties, which had a~~ ~~five-year~~ term to be converted to common stock at an exercise price of $0.004 per share. Persons who were not U.S. citizens held certain of these outstanding warrants. The warrants are exercisable if consistent with federal law, which requires that no more than 24.9% of the Company's stock be voted, directly or indirectly, or controlled by persons who are not U.S. citizens. The warrants can be converted to common stock upon warrant holders demonstrating U.S. citizenship or if consistent with above described federal law ownership limitations. In June 2018, the Company and holders agreed to extend the term of outstanding warrants set to expire by five years (through fiscal year 2023). All of these warrants were converted to common shares as of March 31, 2020.

In July 2018, the Company's Board of Directors and Compensation Committee approved the issuance of shares of restricted common stock under its 2018 Equity Incentive Plan (the "2018 Plan") immediately following completion of the Company's IPO to certain of its employees and directorsAs discussed in exchange for the cancellation of existing restricted phantom stock units, unvested restricted shares, and stock appreciation rights (“SARs”). The shares of restricted common stock issued under the 2018 Plan in exchange for the cancellation of restricted phantom stock units, unvested restricted shares and SARs are subject to vesting on the same terms set forth in the prior vesting schedules and are not subject to acceleration in connection with the 2018 Plan issuances.

On October 30, 2020, the Company entered into the Loan and Guarantee Agreement with the U.S. Treasury and the Bank of New York Mellon, as Administrative and Collateral Agent, under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”).

~~In connection with the Loan and Guarantee Agreement and as partial compensation to the U.S. Treasury for the provision of financial assistance under the Loan and Guarantee Agreement, the Company~~Note 9, we issued warrants to the U.S. Treasury to purchase shares of ~~the Company’s~~our common stock, no par value, at an exercise price of $3.98 per share (the “Exercise Price”), which was the closing price of the common stock on The Nasdaq Stock Market on April 9, 2020.

~~The Company’s~~Our effective tax rate (ETR) from continuing operations was 19.9% and 22.1% for the three and nine months ended June 30, 2022, respectively, and 26.3% and 25.5% for the three and nine months ended June 30, 2021, ~~respectively, and 30.7% and 28.3% for the three and nine months ended June 30, 2020,~~ respectively. The ~~Company's~~Company’s ETR during the three and nine months ended June 30, ~~2021~~2022 was different from the prior year tax rates primarily as a result of the vesting ~~and exercise~~ of stock compensation where the tax deduction state taxes differed from the book expense, changes in the valuation allowance against state net operating losses, and changes in state statutory ~~rates, as well as differences between the book and tax deductions associated with meals, entertainment, employer provide parking, and compensation of officers.~~rates.

~~The restricted share activity for the nine months ended June 30, 2021 is summarized as follows:~~

As of June 30, 2021, there was $5.4 million of total unrecognized compensation cost related to unvested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 2.6 years.

Compensation cost for share-based awards are recognized on a straight-line basis over the vesting period. Share-based compensation expense for the three months ended June 30, 2021 and 2020 was $0.7 million and $1.0 million, respectively~~, and for the nine months ended June 30, 2021 and 2020 was $2.4 million and $3.5 million, respectively.~~

The Company repurchased 139,896 shares of its common stock for $1.4 million to cover the income tax obligation on vested employee equity awards and warrant conversions during the nine months ended June 30, 2021.

~~The Company grants~~We grant restricted stock units (“RSUs”) as part of ~~its~~our long-term incentive compensation to employees and non-employee members of the Board of Directors. RSUs generally vest over a period of 3 to 5 years for employees and one year for members of the Board of Directors. The restricted common stock underlying RSUs are not deemed issued or outstanding upon grant, and do not carry any voting rights.

The restricted share activity for the nine months ended June 30, 2022 is summarized as follows:

As of June 30, 2022, there was $3.8 million of total unrecognized compensation cost related to unvested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.6 years.

Compensation cost for share-based awards is recognized on a straight-line basis over the vesting period. Share-based compensation expense for the three months ended June 30, 2022 and 2021 was $0.7 million and $0.7 million, respectively, and for the nine months ended June 30, 2022 and 2021 was $2.1 million and $2.4 million, respectively.

We repurchased 132,151 shares of our common stock for $0.4 million to cover the income tax obligation on vested employee equity awards during the nine months ended June 30, 2022.

The Mesa Air Group, Inc. 2019 Employee Stock Purchase Plan (the "2019 ESPP”) is a nonqualified plan that provides eligible employees of Mesa Air Group, Inc. with an opportunity to purchase Mesa Air Group, Inc. ordinary shares through payroll deductions. Under the 2019 ESPP, eligible employees may ~~purchase Mesa Air Group, Inc. ordinary shares through the Employee Stock Purchase Plan. Under the 2019 ESPP, eligible employees may~~ elect to contribute 1% to 15% of their eligible compensation during each semi-annual offering period to purchase Mesa Air Group, Inc. ordinary shares at a 10% discount.

A maximum of 500,000 Mesa Air Group, Inc. ordinary shares may be issued under the 2019 ESPP. As of June 30, ~~2021,~~2022, eligible employees purchased and ~~the Company~~we issued ~~157,714~~an aggregate of 247,761 Mesa Air Group, Inc. ordinary ~~shares.~~shares under the 2019 ESPP, 53,567 of which were purchased and issued during the nine months ended June 30, 2022.

As of June 30, ~~2021, the Company~~2022, we leased 1720 aircraft, airport facilities, office space, and other property and equipment under non-cancelable operating leases. The leases generally require ~~the Company~~us to pay all taxes, maintenance, insurance, and other operating expenses. Rental expense is recognized on a straight-line basis over the lease term, net of lessor rebates and other incentives. ~~The Company expects~~We expect that, in the normal course of business, such operating leases that expire will be renewed or replaced by other leases, or the property may be purchased rather than leased.

It is common for us, as the lessee, to agree to indemnify the lessor and the lessor's related parties for tort, environmental and other liabilities that arise out of or relate to our use or occupancy of the leased airport facility and office space premises. This type of indemnity typically makes us responsible to indemnified parties for liabilities arising out of the conduct of, among others, contractors, licensees, and invitees at, or in connection with, the use or occupancy of the leased premises. This indemnity often extends to related liabilities arising from the negligence of the indemnified parties but usually excludes any liabilities caused by either their sole or gross negligence or their willful misconduct.

Our aircraft and other equipment lease and financing agreements typically contain provisions requiring us, as the lessee or obligor, to indemnify the other parties to those agreements, including certain of those parties' related persons, against virtually any liabilities that might arise from the use or operation of the aircraft or other equipment.

We believe that our insurance would cover most of our exposure to liabilities and related indemnities associated with the commercial real estate leases and aircraft and other equipment lease and financing agreements described above. While our insurance does not typically cover environmental liabilities, we have insurance policies in place as required by applicable environmental laws. We cannot reasonably estimate our potential future payments under the indemnities and related provisions described above because we cannot predict (1) when and under what circumstances these provisions may be triggered and (2) the amount that would be payable if the provisions were triggered because the amounts would be based on facts and circumstances existing at such time.

Aggregate rental expense under all operating aircraft, equipment and facility leases totaled approximately ~~$13.9~~$10.8 million and ~~$15.6~~$11.3 million for the three months ended June 30, ~~2021~~2022 and ~~2020,~~2021, respectively, and ~~$41.6~~$33.1 million and ~~$51.0~~$34.0 million for the nine months ended June 30, ~~2021~~2022 and ~~2020,~~2021, respectively.

As of June 30, ~~2021, the Company’s~~2022, our operating leases have a remaining weighted average lease term of ~~2.9~~3.8 years and our operating lease liabilities were measured using a weighted average discount rate of ~~4.2%~~4.5%.

During the nine months ended June 30, 2022, we recorded a $0.2 million impairment of certain operating lease ROU assets associated with the abandonment of a leased facility.

On February 26, 2021, the Company and General Electric Company (“GE”), acting through its GE-Aviation business unit, entered into an Amended and Restated Letter Agreement No. 13-3. ~~The Company~~We agreed to purchase and take delivery of ten (10) new CF34-8C5 or CF34-8E5 engines with delivery dates starting from July 1, 2021 through November 1,^,2022. During the quarter ended March 31, 2021, a $7.0 million non-refundable purchase deposit was made for the first 5 engines to be delivered in calendar 2021. The Company has options to purchase an additional ten (10) similar engines beyond 2022. The total purchase commitment related to these ten (10) engines is approximately ~~$50.0~~$52.2 million. We also have options to purchase an additional ten (10) similar engines beyond 2022. As of June 30, 2022, we have purchased 7 (7) of the engines pursuant to the Amended and Restated Letter Agreement No. 13-3 with delivery of the remaining three (3) engines expected to take place during calendar year 2022.

If ~~the Company fails~~we fail to accept delivery of the spare engines when duly tendered, ~~the Company~~we may be assessed a minimum cancellation charge based on the engine price determined as of the date of scheduled engine ~~delivery to the Company.~~

~~We have~~ ~~certain~~ contracts for goods and services that require us to pay a penalty, acquire inventory specific to us or purchase contract-specific equipment, as defined by each respective contract, if we terminate the contract without cause prior to its expiration date. Because these obligations are contingent on our termination of the contract without cause prior to its expiration date, no obligation would exist unless such a termination occurs.

~~The Company is~~We are subject to 2 putative class action lawsuits alleging federal securities law violations in connection with our IPO, 1 in the Superior Court of the State of Arizona and 1 in U.S. District Court of Arizona. These purported class actions were filed in March and April 2020 against the Company, certain current and former officers and directors, and certain underwriters of the Company’s IPO. The state and federal lawsuits each make the same or similar allegations of

violations of the Securities Act of 1933, as amended, for allegedly making materially false and misleading statements in, or omitting material information from, our IPO registration statement.

On March 2, 2022, the parties in the federal lawsuit attended a mediation and reached an agreement in principle to settle all claims asserted in that action for the sum of $5 million, which will be paid by the Company’s directors’ and officers’ insurance carriers. The ~~plaintiffs seek unspecified monetary damages~~settlement is subject to preliminary and ~~other relief.~~ final approval by the federal court. The motion for preliminary approval was filed on May 6, 2022, and no objections to the settlement were filed by the deadline for such objections. The parties are waiting for the Court to schedule a date for the preliminary approval hearing. If preliminary and final approval is obtained, the claims of all putative class members, whether asserted in the federal or state actions, will be extinguished, unless and only to the extent that a particular class member takes affirmative steps to have its claims excluded.

In addition, we are subject to certain legal actions which we consider routine to our business activities. As of June 30, ~~2021,~~2022, our management believed ~~that~~ the ultimate outcomes of ~~the two putative class action lawsuits and such~~ other routine legal matters are not likely to have a material adverse effect on our financial position, liquidity or results of operations.

We are involved in various legal proceedings (including, but not limited to, insured claims) and FAA civil action proceedings that we do not believe will have a material adverse effect upon our business, financial condition, or results of operations, although no assurance can be given to the ultimate outcome of any such proceedings.

We have certain contracts for goods and services that require us to pay a penalty, acquire inventory specific to us or purchase contract-specific equipment, as defined by each respective contract, if we terminate the contract without cause prior to its expiration date. Because these obligations are contingent on our termination of the contract without cause prior to its expiration date, no obligation would exist unless such a termination occurs.

On July 22, 2022, we amended our United CPA, pursuant to Amendment No. 3 thereto, to among other things, (a) temporarily modify an operational performance metric and related incentives, and (b) amend certain commercial terms set forth in specified schedules to the CPA.

On July 28, 2022, we amended our American CPA, pursuant to Amendment No. 10 thereto, to, among other things, (a) modified certain commercial terms, (b) provide that, commencing with calendar months after January 1, 2022, during any calendar month in which a Notification Shortfall (as defined in the ~~Aircraft Purchase Agreement~~CPA) occurs, bonuses and ~~Series A Preferred Stock Purchase Agreement,~~rebates will not be assessed, (c) reset the ~~Company also obtained a warrant~~CCF and CD0 3-month measurement periods for purposes of American’s termination rights under the CPA to ~~purchase common shares of Heart. The warrant vests~~commence August 2022, and ~~becomes exercisable in tranches upon completion of specified future milestones.~~(d) amended certain other amounts payable to us thereunder.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read together with our condensed consolidated financial statements, the accompanying notes, and the other financial information included elsewhere in this Quarterly Report on Form 10-Q. The following discussion contains ~~forward~~‑~~looking~~forward-looking statements that involve risks and uncertainties such as our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements below. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Quarterly Report on Form 10-Q, particularly in the sections titled "Cautionary Notes Regarding Forward-Looking Statements" above and "Risk Factors" below.

Mesa Airlines is a regional air carrier providing scheduled passenger service to ~~116~~121 cities in 3641 states, the District of Columbia, the Bahamas, and Mexico as well as cargo services out of Cincinnati/Northern Kentucky International Airport. All of our flights are operated as either American Eagle, United Express, or DHL Express flights pursuant to the terms of capacity purchase agreements (“CPAs”) entered into with American Airlines, Inc. (“American”) and United Airlines, Inc. (“United”), and ~~pursuant to the terms of~~ a Flight Services Agreement (“FSA”) with DHL Network Operations (USA), Inc. (“DHL”) (each, our "major partner"). We have a significant presence in several of our major partners' key domestic hubs and focus cities, including Dallas, Houston, Phoenix and Washington-Dulles.

As of June 30, ~~2021,~~2022, our fleet consisted of 168 aircraft which we operated under ~~the~~our CPAs and FSA, leased to a third party, held for sale or maintained as ~~operational~~ spares, ~~a fleet of 155 aircraft~~ with approximately ~~470~~360 daily departures. We ~~also lease 12 aircraft to a third party. We~~ operate 4540 CRJ-900 aircraft under our American CPA and 60 E-175 and 20 E-175LL aircraft under our United CPA. We operate 23 Boeing ~~737-F400~~737-400F aircraft under ~~the FSA with DHL. For the three months ended~~our DHL FSA. As of June 30, ~~2021,~~2022, approximately ~~63%~~65% of our aircraft in scheduled service were operated for United, approximately ~~35%~~33% were operated for American and 2% were operated for DHL. All of our operating revenue in ~~the~~our three and nine months ended June 30, ~~2021~~2022 was derived from operations associated with our American and United CPAs, DHL FSA, and ~~DHL FSA.~~from leases of aircraft to a third party.

Our long-term CPAs provide us guaranteed monthly revenue for each aircraft under contract, a fixed fee for each block hour (the number of hours during which the aircraft is in revenue service, measured from the time of gate departure before take-off until the time of gate arrival at the destination) and ~~flight~~flights actually flown, and reimbursement of certain direct operating expenses in exchange for providing regional flying on behalf of our major partners. Our CPAs also shelter us from many of the elements that cause volatility in airline financial performance, including fuel prices, variations in ticket prices, and fluctuations in number of passengers. In providing regional flying under our CPAs, we use the logos, service marks, flight crew uniforms and aircraft paint schemes of our major partners. Our major partners control route selection, pricing, seat inventories, marketing and scheduling, and provide us with ground support services, airport landing slots and gate access.

Under our DHL FSA, we receive a fee per block hour with a minimum monthly block hour guarantee in exchange for providing cargo flight services. Ground support including fueling and airport fees are paid directly by DHL.

The rapid spread of COVID-19 and the related travel restrictions and social distancing measures implemented throughout the world significantly reduced demand for air travel beginning in the quarter ended March 31, 2020. This reduction in demand had an unprecedented and materially adverse impact on our revenues and financial position in ~~the prior year~~both fiscal 2020 and 2021 that has continued into fiscal ~~year 2021. However, as discussed further below,~~2022. While there was a moderate increase in demand for air travel beginning in fiscal 2021, we ~~experienced improvement in our financial results~~continue to be impacted by the direct and indirect effects of the virus, including increased employee attrition and employee absence rates, and a decrease in the ~~quarter ended June 30, 2021, which we expect to continue~~supply of qualified pilots. The exact timing and pace of the ~~remainder~~recovery is uncertain given the significant impact of ~~fiscal 2021.~~

~~The funds~~ the Company received under the Payroll Support Program and its Loan and Guarantee Agreement with the U.S. Treasury, coupled with the Company’s diligent cost saving, have helped to partially offset the negative impacts of COVID-19pandemic on the ~~Company’s business.~~overall U.S. and global economy, as well as the uncertainty of certain factors outside of our control including current or future travel restrictions, vaccination effectiveness, vaccine mandates, and future variants of the virus. Since a portion of our revenue is fixed due to the structure of our CPAs, the impact ofto Mesa from the COVID-19 ~~on the Company’s operations~~pandemic has been ~~less severe.~~partially mitigated. In addition, ~~we have limited~~our exposure to fluctuations in passenger traffic, ticket and fuel ~~prices.~~prices is limited.

The following discussion summarizes the key components of our condensed consolidated statements of ~~operations.~~operations and comprehensive income (loss).

Our ~~condensed consolidated~~ operating revenues consist primarily of contract revenue as well as pass-through and other revenues.

Contract Revenue. Contract revenue consists of the fixed monthly amounts per aircraft received pursuant to our ~~capacity purchase agreements~~CPAs and ~~flight services agreement~~FSA with our major partners, along with the additional amounts received based on the number of flights and block hours flown, and rental revenue for aircraft leased to ~~GoJet.~~GoJet Airlines LLC. Contract revenues we receive from our major partners are paid and recognized ~~by us on a weekly basis.~~over time consistent with the delivery of service under our CPAs and FSA.

Pass-Through and Other Revenue. Pass-through and other revenue consists of passenger and hull insurance, aircraft property taxes, landing fees, and other ~~direct~~aircraft and traffic servicing costs ~~and~~received pursuant to our agreements with our major partners, as well as certain maintenance costs related to our E-175 aircraft.

Flight Operations. Flight operations expense includes costs related to salaries, bonuses and benefits earned by our pilots, flight attendants, and dispatch personnel, as well as costs related to technical publications, lodging of our flight crews and pilot training expenses.

~~Fuel.~~ Fuel expense includes fuel and related fueling costs for flying we undertake outside of our capacity purchase agreements and flight service agreement, including aircraft repositioning and maintenance. All aircraft fuel and related fueling costs for flying under our capacity purchase agreements were directly paid and supplied by our major partners. The fuel and related cost for flying under our FSA were directly paid and supplied by DHL. We do not record an expense or the related revenue for fuel supplied by American and United for flying under our capacity purchase agreements or DHL under our FSA.

Maintenance. Maintenance expense includes ~~routine repair~~costs related to engine overhauls, airframe, landing gear and normal recurring maintenance, ~~and heavy~~which includes pass-through maintenance costs ~~for airframes, engines, auxiliary power units and landing gears.~~related to our E-175 aircraft. Heavy maintenance and major overhaul costs on our owned E-175 fleet are deferred and amortized until the earlier of the end of the useful life of the related asset or the next scheduled heavy maintenance event. All other maintenance costs are expensed as incurred, except for certain maintenance contracts where labor and materials price risks have been transferred to the service provider and require payment on a utilization basis, such as flight hours. Costs incurred for maintenance and repair for utilization maintenance contracts where labor and materials price risks have been transferred to the service provider are charged to maintenance expense based on contractual payment terms. As a result of using the direct expense method for heavy maintenance on the majority of our fleets, the timing of maintenance expense reflected in the financial statements may vary significantly from period to period.

Aircraft Rent. Aircraft rent expense includes costs related to leased engines and aircraft.

~~Aircraft and Traffic Servicing.~~ Aircraft and traffic servicing expense includes expenses related to our capacity purchase agreements, including aircraft cleaning, passenger disruption reimbursements, international navigation fees and wages of airport operations personnel, a portion of which are reimbursable by our major partners.

General and Administrative. General and administrative expense includes insurance and taxes, the majority of which are pass-through costs, non-operational administrative employee wages and related expenses, building rents, real property leases, utilities, legal, audit and other administrative expenses.

Depreciation and Amortization. Depreciation expense is a periodic non-cash charge primarily related to aircraft, engine, and equipment depreciation. Amortization expense is a periodic non-cash charge related to our customer relationship intangible asset.

Impairment of Assets Held for Sale. Impairment of assets held for sale includes charges for impairments of our assets held for sale, including changes in the fair value of assets held for sale.

Other Operating Expenses. Other operating expenses primarily consists of fuel costs for flying we undertake outside of our CPAs and FSA (including aircraft re-positioning and maintenance) as well as costs for aircraft and traffic servicing, such as aircraft cleaning, passenger disruption reimbursements, international navigation fees and wages of airport operations personnel, a portion of which are reimbursable by our major partners. All aircraft fuel and related fueling costs for flying under our CPAs and FSA are directly paid and supplied by our major partners. Accordingly, we do not record an expense or pass-through revenue for fuel supplied by American and United for flying under our CPAs or DHL under our FSA.

Interest Expense. Interest expense is interest on our debt incurred to finance purchases of aircraft, engines, and equipment, including amortization of debt financing ~~costs.~~costs and discounts.

Interest Income. Interest income includes interest income on our cash and cash equivalent balances.

Loss on Investments, Net. Loss on investments consists of net losses on our investments in equity securities resulting from changes in the fair value of the equity securities.

Other Expense. Other expense includes expense derived from activities not classified in any other area of the condensed consolidated statements of operations and comprehensive income ~~including write-offs of miscellaneous third-party fees.~~(loss).

Operating segments are defined as components of an enterprise about which discrete financial information is available that is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing

operating performance. In consideration of ASC 280, ~~"Segment~~Segment Reporting", we are not organized around specific services or geographic regions. We currently operate in one service line providing scheduled flight services in accordance with our capacity purchase agreements and flight services agreement.

While we operate under two separate capacity purchase agreements and one flight services agreement, we do not manage our business based on any performance measure at the individual contract level. Additionally, our ~~chief operating decision maker (“~~CODM”) uses ~~condensed~~ consolidated financial information to evaluate our performance, which is the same basis on which he communicates our results and performance to our Board of Directors. The CODM bases all significant decisions regarding the allocation of our resources on a consolidated basis. Based on the information described above and in accordance with the applicable literature, management has concluded that we are organized and operated as one operating and reportable segment.

We had operating income of $0.2 million in our three months ended June 30, 2022 compared to operating income of $14.4 million in our three months ended June 30, 2021. In our three months ended June 30, 2022, we had net loss of $10.0 million compared to net income of $4.3 million in our three months ended June 30, 2021.

Our operating results for the three months ended June 30, 2022 reflect an increase in flight operations expense resulting from increased pilot training as well as a decrease in maintenance expense mainly as a result of fewer C-checks. Additionally, there were no government grant funds utilized as an offset to operating expenses during the three months ended June 30, 2022, compared to $26.1 million during the three months ended June 30, 2021.

"Available seat miles" or "ASMs" means the number of seats available for passengers multiplied by the number of miles the seats are flown.

"Average stage length" means the average number of statute miles flown per flight segment.

“Block hours” means the number of hours during which the aircraft is in revenue service, measured from the time of gate departure before take-off until the time of gate arrival at the destination.

Total operating revenue increased by $9.2 million, or 7.4%, to $134.4 million for our three months ended June 30, 2022 as compared to our three months ended June 30, 2021. Contract revenue increased by $9.2 million, or 8.4%, to $118.9 million primarily due to normalized contractual rates from our major partners and recognition of higher deferred revenue, partially offset by reduced block hours flown compared to the three months ended June 30, 2021. The increase in rates compared to the three months ended June 30, 2021 is attributable to temporarily reduced rates from our major partners impacting the three months ended June 30, 2021 as a result of lower labor costs due to government assistance received during the same period. Our block hours flown during our three months ended June 30, 2022, decreased 25.5% compared to the three months ended June 30, 2021 due to a decrease in scheduled flying for our major partners across all fleets. Our pass-through and other revenue remained static during our three months ended June 30, 2022.

Flight Operations. Flight operations expense increased $1.9 million, or 4.7%, to $43.3 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021. The increase was primarily driven by an increase in pilot training-related costs.

Maintenance. Aircraft maintenance expense decreased $2.3 million, or 4.4%, to $49.7 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021. This decrease was primarily driven by a lower volume of airframe C-checks, partially offset by increases in pass-through engine overhauls, labor, and other maintenance expenses. Total pass-through maintenance expenses reimbursed by our major partners decreased by $0.3 million during our three months ended June 30, 2022 compared to our three months ended June 30, 2021.

The following table presents information regarding our maintenance costs during the three months ended June 30, 2022 and 2021 (in thousands):

Aircraft Rent. Aircraft rent expense decreased $0.3 million, or 3.6%, to $9.3 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021. This was primarily driven by lower engine rent expense.

General and Administrative. General and administrative expense decreased $1.0 million, or 8.1%, to $11.1 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021. The decrease is primarily due to a decrease in property taxes. For our three months ended June 30, 2022 and 2021, $2.3 million and $3.3 million, respectively, of our insurance and property tax expenses were reimbursed by our major partners.

Depreciation and Amortization. Depreciation and amortization expense decreased by $0.8 million, or 4.0%, to $20.1 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021.

Other Operating Expenses. Other operating expenses decreased $0.2 million, or 21.2%, to $0.7 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021. The decrease is primarily attributable to a decrease in aircraft depreciation expense as a result of a portion of our fleet being classified as held for sale during the three months ended June 30, 2022, offset by an increase in spare engine depreciation expense as well as amortization of deferred heavy maintenance. The decrease is primarily driven by a decrease in aircraft cleaning expense.

Government Grant Recognition. Recognition of payroll support funds decreased $26.1 million, or 100.0%, to $0.0 million for our three months ended June 30, 2022 compared to our three months ended June 30, 2021. Under the American Recovery Plan Act of 2021, the government provided the Company with a grant of $52.2 million in payroll support, of which $26.1 million was recognized as an offset to operating expense during the three months ended June 30, 2021. There were no government grant funds received by the Company recognized as an offset to operating expense during the three months ended June 30, 2022.

Other expense increased $4.1 million, or 48.0%, to $12.7 million for our three months ended June 30, 2022, compared to our three months ended June 30, 2021. The increase is primarily attributable to net losses on investments in equity securities of $3.9 million.

Our effective tax rate (ETR) from continuing operations was 19.9% for the three months ended June 30, 2022 and 26.3% for the three months ended June 30, 2021. Our ETR during the three months ended June 30, 2022 decreased from the prior year tax rate, primarily as a result of certain permanent tax differences, state taxes, and changes in the valuation allowance against state net operating losses.

We continue to maintain a valuation allowance on a portion of our state net operating losses in jurisdictions with shortened carryforward periods or in jurisdictions where our operations have significantly decreased as compared to prior years in which the net operating losses were generated.

As of September 30, 2021, the Company had aggregate federal and state net operating loss carryforwards of $541.3 million and $235.7 million, respectively, which expire in 2027-2038 and 2022-2041, respectively. Approximately $1.2 million of state net operating loss carryforwards are expected to expire in the current year.

We had operating loss of $48.5 million in our nine months ended June 30, 2022 compared to operating income of $58.1 million in our nine months ended June 30, 2021. In our nine months ended June 30, 2022, we had net loss of $67.0 million compared to net income of $24.1 million in our nine months ended June 30, 2021.

Our operating results for the nine months ended June 30, 2022 reflect an increase in flight operations expense due to higher pilot and flight attendant wages, lodging, and training expenses. We also recognized impairment charges of $39.5 million on certain of our CRJ aircraft classified as held for sale during the nine months ended June 30, 2022, as described in Note 6 to the condensed consolidated financial statements. Additionally, there were no government grant funds utilized as an offset to operating expenses during the nine months ended June 30, 2022, compared to $93.4 million during the nine months ended June 30, 2021. Lastly, our general and administrative expense decreased due to lower pass-through insurance costs.

Flight Operations. Flight operations expense increased $17.6 million, or 15.2%, to $133.3 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The increase was primarily driven by an increase in pilot wages and pilot training-related costs.

Maintenance.Aircraft maintenance expense decreased $0.6 million, or 0.4%, to $156.0 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The decrease was primarily due to the reduction in engine overhaul and C-check costs, which was offset by the increase in parts and labor costs. Total pass-through

maintenance expenses reimbursed by our major partners decreased by $10.7 million during our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021.

The following table presents information regarding our maintenance costs during our nine months ended June 30, 2022 and 2021 (in thousands):

Aircraft Rent. Aircraft rent expense decreased $1.4 million, or 4.6%, to $28.3 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The decrease is attributable to a decrease in engine rent due to fewer leased engines and decrease in aircraft rent due to the purchase of a CRJ-900 aircraft during fiscal 2021 that was previously under lease.

General and Administrative. General and administrative expense decreased $4.8 million, or 13.1%, to $31.6 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The decrease is primarily due to a decrease in pass-through property taxes. For our nine months ended June 30, 2022 and 2021, $5.5 million and $10.7 million, respectively, of our insurance and property tax expenses were reimbursed by our major partners.

Depreciation and Amortization. Depreciation and amortization expense decreased $0.2 million, or 0.4%, to $61.9 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The decrease is primarily attributable to a portion of our fleet being classified as held for sale during the nine months ended June 30, 2022, offset by an increase in rotable part and spare engine depreciation expense as well as amortization of deferred heavy maintenance.

Lease Termination. Lease termination expense decreased $4.5 million, or 100.0%, to zero for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. This decrease is attributable to the termination expense resulting from the purchase of a CRJ-900 aircraft during our nine months ended June 30, 2021, which was previously leased from Bombardier Capital.

Impairment of Assets Held for Sale. Impairment of assets held for sale was $39.5 million for our nine months ended June 30, 2022 compared to $0.0 million for our nine months ended June 30, 2021. The increase is attributable to impairment charges on our CRJ aircraft classified as held for sale during the nine months ended June 30, 2022.

Other Operating Expenses. Other operating expenses remained static for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The slight increase is primarily due to higher fuel costs offset by lower aircraft cleaning expenses during the nine months ended June 30, 2022.

Government Grant Recognition. Recognition of payroll support funds decreased $93.4 million, or 100.0%, to $0.0 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. During the nine months ended June 30, 2021, we recognized $93.4 million in payroll support from the Payroll Support Program and its extensions as an offset to operating expense. There were no government grant funds received by the Company recognized as an offset to operating expenses during the nine months ended June 30, 2022.

Other expense increased $11.7 million, or 45.4%, to $37.5 million for our nine months ended June 30, 2022 compared to our nine months ended June 30, 2021. The increase is primarily attributable to net losses on investments in equity securities of $12.6 million, partially offset by a decrease in interest expense of $1.7 million due to lower interest rates on our Treasury Loan and a decrease in outstanding aircraft principal balances.

The income tax benefit totaled $19.0 million for the nine months ended June 30, 2022 as compared to a tax expense of $8.2 million for the nine months ended June 30, 2021. The effective tax rate (ETR) was 22.1% for the nine months ended June 30, 2022 compared to 25.5% for the nine months ended June 30, 2021. The ETR for the nine months ended June 30, 2022 was impacted by vesting of stock compensation where the tax deduction differed from the book expense, state taxes, changes in the valuation allowance against state net operating losses, and changes in state statutory rates.

We present Adjusted EBITDA and Adjusted EBITDAR, which are not recognized financial measures under GAAP, in this Quarterly Report on Form 10-Q as supplemental disclosures because our senior management believes that they are well-recognized valuation metrics in the airline industry that are frequently used by companies, investors, securities analysts and other interested parties in comparing companies in our industry.

Adjusted EBITDA. We define Adjusted EBITDA as net income or loss before interest, income taxes, and depreciation and amortization, adjusted for ~~the impact of revaluation of liability awards,~~gains and losses on investments, lease termination costs, ~~loss~~impairment charges, and gains or losses on extinguishment of debt ~~and~~including write-off of associated financing fees.

Adjusted EBITDAR. We define Adjusted EBITDAR as net income or loss before interest, income taxes, depreciation and amortization, and aircraft rent, adjusted for ~~the impact of revaluation of liability awards,~~gains and losses on investments, lease termination costs, ~~loss~~impairment charges, and gains or losses on extinguishment of debt ~~and~~including write-off of associated financing fees.

Adjusted EBITDA and Adjusted EBITDAR have limitations as analytical tools. Some of the limitations applicable to these measures include: (i) Adjusted EBITDA and Adjusted EBITDAR do not reflect the impact of certain cash charges resulting from matters we consider not to be indicative of our ongoing operations; (ii) Adjusted EBITDA and Adjusted EBITDAR do not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments; (iii) Adjusted EBITDA and Adjusted EBITDAR do not reflect changes in, or cash requirements for, our working capital needs; (iv) Adjusted EBITDA and Adjusted EBITDAR do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debts; (v) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future; (vi) Adjusted EBITDA and ~~(vi)~~Adjusted EBITDAR do not reflect gains and losses on investments, which are non-cash gains and losses but will occur in periods when there are changes in the value of our investments in equity securities; and (vii) Adjusted EBITDA and Adjusted EBITDAR do not reflect any cash requirements for such replacements and other companies in our industry may calculate Adjusted EBITDA and Adjusted EBITDAR differently than we do, limiting its usefulness as a comparative measure. Because of these limitations, Adjusted EBITDA and Adjusted EBITDAR should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. In addition, Adjusted EBITDAR should not be viewed as a measure of overall performance because it excludes aircraft rent, which is a normal, recurring cash operating expense that is necessary to operate our business. For the foregoing reasons, each of Adjusted EBITDA and Adjusted EBITDAR has significant limitations which affect its use as an indicator of our profitability. Accordingly, you are cautioned not to place undue reliance on this information.

~~Three Months Ended June 30, 2021 Compared to Three Months Ended June 30, 2020~~

We had operating income of $14.4 million in our three months ended June 30, 2021 compared to operating income of $15.2 million in our three months ended June 30, 2020. In our three months ended June 30, 2021, we had net income of $4.3 million compared to net income of $3.4 million in our three months ended June 30, 2020. Our operating results for the three months ended June 30, 2021 reflected an increase in contract and pass-through revenue due to the lessened impact of COVID-19 as compared to the quarter ended June 30, 2020.

Flight operations expense increased in the three months ended June 30, 2021 due to higher pilot and flight attendant wages and pilot training expenses. Our maintenance expense increased primarily due to a higher number of C-check events, higher utilization of component contracts, higher pass-through maintenance, and higher labor expense. Aircraft rent expense decreased primarily due to fewer leased engines. Lastly, we recognized the Federal Grant received through the Payroll Support Agreement under the CARES Act with the U.S. Department of the Treasury.

~~"Available seat miles" or "ASMs" means the number of seats available for passengers multiplied by the number of miles the seats are flown.~~

~~“Block hours” means the number of hours during which the aircraft is in revenue service, measured from the time of gate departure before take-off until the time of gate arrival at the destination.~~

~~"Average stage length" means the average number of statute miles flown per flight segment.~~

Total operating revenue increased by $52.1 million, or 71.2%, to $125.2 million for our three months ended June 30, 2021 as compared to our three months ended June 30, 2020. Contract revenue increased by $38.0 million, or 53.0%, to $109.7 million primarily due to increased flying on our CRJ-900 and E-175 fleets and increased demand for air travel as state and local governments in the United States continue to lift travel and gathering restrictions, partially offset by a temporary reduction in rates to our major partners and flying fewer aircraft under the American CPA. Our block hours flown during our three months ended June 30, 2021, increased 169.3% compared to the three months ended June 30, 2020 due to increased flying across all fleets. Our pass-through and other revenue increased during our three months ended June 30, 2021 by $14.1 million, or 968.4%, to $15.5 million primarily due to increased pass-through maintenance on all fleets.

~~Flight Operations.~~ Flight operations expense increased $11.7 million, or 39.3%, to $41.3 million for our three months ended June 30, 2021 compared to the same period in 2020. The increase was primarily driven by an increase in pilot and flight attendant wages due to higher block hours as well as pilot training related costs.

~~Fuel.~~ Fuel expense increased $0.1 million, or 60.3%, to $0.2 million for our three months ended June 30, 2021 compared to the same period in 2020. The increase was primarily driven by fuel expense related to C-checks and ferry flights. All fuel costs related to flying under our capacity purchase agreements during our three months ended June 30, 2021 and 2020 were directly paid to suppliers by our major partners.

~~Maintenance.~~ Aircraft maintenance costs increased $29.4 million, or 130.1%, to $52.0 million for our three months ended June 30, 2021 compared to the same period in 2020. This increase was primarily driven by increases in C-checks, component contracts, parts, pass-through maintenance, and labor and other expense and availability of parts for certain fleets. Total pass-through maintenance expenses reimbursed by our major partners increased by $15.0 million during our three months ended June 30, 2021.

~~The following table presents information regarding our maintenance costs during the three months ended June 30, 2021 and 2020 (in thousands):~~

~~Aircraft Rent.~~ Aircraft rent expense decreased $5.9 million, or 38.1%, to $9.6 million for our three months ended June 30, 2021 compared to the same period in 2020. The decrease is attributable to a decrease in engine rent due to fewer leased engines as well as a decrease in rent expense from aircraft leases due to the Company’s purchase of a previously leased aircraft in March 2021.

~~Aircraft and Traffic Servicing.~~ Aircraft and traffic servicing expense increased $0.1 million, or 26.8%, to $0.7 million for our three months ended June 30, 2021 compared to the same period in 2020. The increase is primarily due to an increase in pass-through legal and regulatory charges.

~~General and Administrative.~~ General and administrative expense increased $0.4 million, or 3.0%, to $12.1 million for our three months ended June 30, 2021 compared to the same period in 2020. The increase is primarily due to an increase in wages and labor as well as liability insurance, offset by a decrease in property taxes. For our three months ended June 30, 2021 and 2020, $3.3 million and $3.9 million, respectively, of our insurance and property tax expenses were reimbursed by our major partners.

~~Depreciation and Amortization.~~ Depreciation and amortization expense increased $0.3 million, or 1.4%, to $20.9 million for our three months ended June 30, 2021 compared to the same period in 2020. The increase is primarily attributable to an increase in rotable inventory and deferred heavy maintenance depreciation expense, partially offset by a decrease in intangible asset amortization expense.

~~Government Grant Recognition.~~ Payroll support government plan funds decreased $16.9 million, or 39.3%, to $26.1 million for our three months ended June 30, 2021 compared to the same period in 2020. The decrease is primarily due to the timing of receipt and recognition of payroll support funds in the prior period.

Other expense decreased $1.7 million, or 16.7%, to $8.6 million for our three months ended June 30, 2021, compared to the same period in 2020. The decrease is primarily a result of a decrease in interest expense due to a decrease in outstanding aircraft principal balances and lower interest rates resulting from the Loan and Guarantee Agreement with the U.S. Department of the Treasury.

The Company's effective tax rate (ETR) from continuing operations was 26.3% for the three months ended June 30, 2021 and 30.7% for the three months ended June 30, 2020. The Company's ETR during the three months ended June 30, 2021 was different from the U.S. federal statutory rate of 21% primarily due to permanent book and tax deductible expense differences, vesting of stock compensation where the tax deduction differed from the book expense, state taxes, changes in the valuation allowance against state net operating losses, and changes in state apportionment and state statutory rates. We continue to maintain a valuation allowance on a portion of our state net operating losses in jurisdictions with shortened carryforward periods or in jurisdictions where our operations have significantly decreased as compared to prior years in which the net operating losses were generated.

The Company's current year effective tax rate decreased compared to the prior year tax rate as a result of an increase to the forecast for the current fiscal year, as the Company's permanent differences between book and taxable income therefore have less of an impact on the Company's effective tax rate. In addition, the Company's rate varied from the prior year's as a result of the vesting of stock compensation where the tax deduction differed from the book expense, state taxes, changes in the valuation allowance against state net operating losses, and changes in state statutory rates.

As of September 30, 2020, the Company had aggregate federal and state net operating loss carryforwards of $512.6 million and $223.9 million, respectively, which expire in 2027-2038 and 2021-2040, respectively. Approximately $0.7 million of state net operating loss carryforwards are expected to expire in the current year.

~~We had operating income of $58.1 million~~ in our nine months ended June 30, 2021 compared to operating income of $56.3 million in our nine months ended June 30, 2020. In our nine months ended June 30, 2021, we had net income of $24.1 million compared to net income of $16.0 million in our nine months ended June 30, 2020. Our operating results for the nine months ended June 30, 2021 reflected a decrease in contract revenue primarily due to lower flying due to the impact of COVID-19, and an increase in pass-through and other revenues primarily due to an increase in pass-through maintenance.

Flight operations expense decreased in the nine months ended June 30, 2021 due to lower pilot and flight attendant wages and pilot training expenses. Our maintenance expense increased primarily due to a higher number of C-checks and higher component contracts, and higher pass-through maintenance, offset by lower maintenance expense related to engine overhauls, labor, and parts. Aircraft rent expense decreased primarily due fewer leased engines. In addition, general and

administrative expense decreased as a result of lower pass-through property taxes. Lastly, we recognized the Federal Grant received through the Payroll Support Agreement under the CARES Act with the U.S. Department of the Treasury.

Total operating revenue decreased by $64.2 million, or 14.7%, to $372.8 million for our nine months ended June 30, 2021 as compared to our nine months ended June 30, 2020. Contract revenue decreased by $90.7 million, or 22.2%, to $318.5 million primarily due to a decrease in flying as a result of the impact of the COVID-19 pandemic including travel restrictions beginning in our second fiscal quarter of 2020, a temporary reduction in rates to our major partners and ~~flying fewer aircraft under the American CPA~~. Our block hours flown during our nine months ended June 30, 2021 decreased 10.6% compared to the nine months ended June 30, 2020 primarily due to decreased flying on our CRJ-900, CRJ-700, and E-175 fleets. Our pass-through and other revenue increased during our nine months ended June 30, 2021 by $26.5 million, or 95.3%, to $54.3 million primarily due to pass-through maintenance revenue related to our E-175 fleet.

~~Flight Operations.~~ ~~Flight operations expense decreased $19.5 million, or 14.4%, to $115.7 million for our nine months ended June 30, 2021 compared to the same period in 2020.~~ ~~The decrease was primarily driven by a decrease in pilot and flight attendant wages due to lower block hours as well as lower pilot training related costs.~~

~~Fuel.Fuel expense increased $0.3 million, or 63.1%, to $0.8 million for our nine months ended June 30, 2021 compared to the same period in 2020.~~ ~~The increase was primarily driven by fuel expense related to the delivery of the new~~

~~E-175 aircraft~~. All fuel costs related to flying under our capacity purchase agreements and flight services agreement during our nine months ended June 30, 2021 and 2020 were directly paid to suppliers by our major partners.

~~Maintenance.~~Aircraft maintenance costs increased $11.6 million, or 8.0%, to $156.6 million for our nine months ended June 30, 2021 compared to the same period in 2020. This increase was primarily driven by an increase in C-check expense and pass through maintenance. This increase was partially offset by a decrease in engine overhaul, labor, and parts. Total pass-through maintenance expenses reimbursed by our major partners increased by $29.9 million during our nine months ended June 30, 2021.

~~The following table presents information regarding our maintenance costs during our nine months ended June 30, 2021 and 2020 (in thousands):~~

~~Aircraft Rent.~~ ~~Aircraft rent expense decreased $9.5 million, or 24.3%, to $29.7 million for our nine months ended June 30, 2021 compared to the same period in 2020.~~ ~~The decrease is attributable to a decrease in engine rent due to fewer leased engines.~~

~~Aircraft and Traffic Servicing.~~ Aircraft and traffic servicing expense decreased $0.6 million, or 20.8%, to $2.3 million for our nine months ended June 30, 2021 compared to the same period in 2020. The decrease is primarily due to a decrease in interrupted trip expense and pass-through regulatory charges, partially offset by an increase in pass-through legal fees related to our GoJet leases.

~~General and Administrative.~~ General and administrative expense decreased $2.9 million, or 7.4%, to $36.3 million for our nine months ended June 30, 2021 compared to the same period in 2020. The decrease is primarily due to a decrease in pass-through property taxes. For our nine months ended June 30, 2021 and 2020, $10.7 million and $13.2 million, respectively, of our insurance and property tax expenses were reimbursed by our major partners.

~~Depreciation and Amortization.~~ ~~Depreciation and amortization expense increased $0.5 million, or 0.7%, to $62.1 million for our nine months ended June 30, 2021 compared to the same period in 2020.~~ ~~The increase is primarily attributable to an increase in rotables and spare engines depreciation expense, partially offset by a decrease in amortization of intangibles expense.~~

~~Lease Termination.~~ Lease termination expense increased $4.5 million, or 100.0%, to $4.5 million for our nine months ended June 30, 2021 compared to the same period in 2020. This increase is attributable to the termination expense resulting from the purchase of a CRJ-900 aircraft, which was previously leased from Bombardier Capital.

~~Government Grant Recognition.~~ Payroll support government plan funds increased $50.4 million, or 117.1%, to $93.4 million for our nine months ended June 30, 2021 compared to the same period in 2020. Under the Consolidated Appropriations Act, the government provided the Company with a grant of $56.0 million in payroll support for the period of December 2020 through March 2021, and an additional $52.2 million in payroll support under the American Recovery Plan Act for the period of April 2021 through September 2021, of which, $26.1 million has been recognized as of June 30, 2021. We also recognized $11.3 million of the grant amount received for the period of April through October 2020 during the quarter ended December 31, 2020.

~~Other expense decreased $8.1 million, or 23.8%, to $25.8 million for our nine months ended June 30, 2021, compared to the same period in 2020.~~ The decrease is primarily a result of a decrease in interest expense due to lower interest rates on our loan agreement with the U.S. Department of the Treasury and a decrease in outstanding aircraft principal balances.

The income tax expense totaled $8.2 million for the nine months ended June 30, 2021 as compared to a tax expense of $6.4 million for the nine months ended June 30, 2020. The effective tax rate was 25.5% versus 28.3% in the prior year.

The effective tax rate for the nine months ended June 30, 2021 was impacted by vesting of stock compensation where the tax deduction differed from the book expense, state taxes, changes in the valuation allowance against state net operating losses, and changes in state statutory rates.

We file income tax returns in the US and in various state jurisdictions with varying statutes of limitations. We are generally no longer subject to income tax examination by tax authorities for years prior to 2017 and 2016 for federal and state purposes, respectively, except for the examination of our net operating losses. The balance of unrecognized tax benefits is not anticipated to fluctuate significantly from fiscal 2020 to fiscal 2021. It is our policy to recognize interest expense and penalties related to uncertain income tax matters as a component of income tax expense.

The length and severity of the pilot shortage, which has impacted the US passenger and cargo carriers, remains uncertain. One of the primary factors contributing to the pilot shortage includes the demand for pilots at major carriers, which are hiring at an accelerated rate to backfill the thousands of pilots whom they offered early retirements to at the beginning of the pandemic. These airlines now seek to increase their capacity to meet the growing demand for air travel as the global pandemic has moderated. A primary source of pilots for the major US passenger and cargo carriers are the US regional airlines.

As a result of the ~~COVID-19 pandemic,~~pilot shortage, elevated pilot attrition and its negative impact on our financial results, we ~~undertook~~have taken, and are continuing to take, certain actions ~~in 2020 and the early part of 2021~~ to increase liquidity and strengthen our financial position. These actions included working with our major partners and original equipment manufacturers ("OEM") to delay the timing of our future aircraft and spare engine deliveries, delaying non-essential heavy maintenance, and reducing or suspending other discretionary spending.position which include:

In February 2021, the Company was granted $48.7 million in financial assistance by the U.S. Department of the Treasury under the Payroll Support Program Extension (“PSP2”) under the Consolidated Appropriations Act of 2021. In March 2021, we were notified that, based on funding availability, recipients that were currently in compliance with executed PSP agreements would receive an additional award amount. As a result, the Company was granted an additional $7.3 million through the PSP2 for a total grant of $56.0 million. The additional $7.3 million was received in April 2021.

~~On April 15, 2021,~~While there is no guarantee that these initiatives will come to fruition or otherwise achieve their desired objective, we believe it is probable that the initiatives outlined above, along with the cash flow from operating activities and cash on hand will provide us with adequate cash resources to maintain our operations and comply with our various debt and other contractual agreements, through at least the next 12 months.

As of June 30, 2022, the Company ~~was notified~~has $112.8 million of principal maturity payments on long-term debt due within the next twelve months. We plan to meet these obligations with our cash on hand, ongoing cashflows from our operations, as well as the liquidity created from our plans to sell 18 CRJ-700 aircraft, refinance our revolving credit facility, and further amend of CPAs. If our plans are not realized, this will necessitate exploring additional opportunities to create liquidity by refinancing and deferring repayment of our principal maturity payments that are due within the U.S. Department of the Treasury we were eligible to receive funds under the third Payroll Support Program (“PSP3”), which was created under the American Recovery Plan Act of 2021 (“ARPA”), enacted on March 11, 2021. The amount of financial assistance received by the Company was approximately $52.2 million.next twelve months. The Company ~~received the first installment of $26.1 million in April 2021 and the second installment of $26.1 million in May 2021.~~

~~On October 30, 2020, the Company entered into~~continues to monitor covenant compliance with its lenders as any noncompliance could have a Loan and Guarantee Agreement with the U.S. Department of the Treasury for a secured loan facility of up to $200.0 million that matures in October 2025 (the “Treasury Loan”). On October 30, 2020, the Company borrowed $43.0 million and on November 13, 2020, the Company borrowed an additional $152.0 million. No further borrowings are available under the Treasury Loan.

We require cash to fund our operating expenses and working capital requirements, including outlays for capital expenditures, aircraft pre-delivery payments, maintenance, aircraft rent, and ~~to pay~~ debt service obligations, including principal and interest payments. Our cash needs vary from period to period primarily based on the timing and costs of significant maintenance events. Our principal sources of liquidity are ~~the cash grant we received under the payroll support programs (PSP, PSP2, PSP3) and the funds received under our Treasury Loan,~~ cash on hand, cash generated from operations and funds from external borrowings.

We believe that the key factors that could affect our internal and external sources of cash include:

Our ability to service our long-term debt obligations, including our equipment notes, to remain in compliance with the various covenants contained in our debt agreements and to fund working capital, capital expenditures and business development efforts will depend on our ability to generate cash from operating activities, which is subject to, among other things, our future operating performance, as well as other factors, some of which may be beyond our control.

If we fail to generate sufficient cash from operations, we may need to raise additional equity or borrow additional funds to achieve our longer-term objectives. There can be no assurance that such equity or borrowings will be available or, if available, will be at rates or prices ~~and other terms~~ acceptable to us.

We believe that cash flow from operating activities coupled with existing cash and cash equivalents, short-term investments, existing credit facilities, financing arrangements and government assistance under the CARES Act, will be adequate to fund our operating and capital needs, as well as enable us to maintain compliance with our various debt agreements, through at least the next 12 months. To the extent that results, or events, differ from our financial projections or business plans, our liquidity may be adversely impacted.

During the ordinary course of business, we evaluate our cash requirements and, if necessary, adjust operating and capital expenditures to reflect the current market conditions and our projected demand. Our capital expenditures are primarily directed toward our aircraft fleet and flight ~~equipment.~~equipment including spare engines. Our capital expenditures, net of purchases of rotable spare parts and aircraft and spare engine financing for the nine months ~~ending~~ended June 30, ~~2021 is~~2022 were approximately ~~1.9%~~0.9% of ~~annual revenue.~~our revenue during the same period. We expect to incur capital expenditures to support our business activities. Future capital expenditures may be impacted by events and transactions that are not currently forecasted.

As of June 30, ~~2021,~~2022, our principal sources of liquidity were cash and cash equivalents of ~~$180.4~~$54.4 million. In addition, we had restricted cash of ~~$3.4~~$3.3 million as of June 30, ~~2021.~~ 2022. As of June 30, ~~2021,~~2022, we ~~also~~ had ~~$707.0~~$634.9 million in secured indebtedness incurred primarily in connection with our financing of ~~aircraft.~~84 total aircraft and related equipment. As of June 30, ~~2021,~~2022, we had ~~$105.4~~$109.5 million of ~~short-term~~current debt, excluding ~~capital~~finance leases, and ~~$603.1~~$525.4 million of long-term debt excluding ~~capital~~finance leases.

As of June 30, ~~2021,~~2022, we had ~~$3.4~~$3.3 million in restricted cash. We have an agreement with a financial institution for a letter of credit facility and to issue letters of credit for particular airport authorities, worker's compensation insurance, property and casualty insurance and other business needs as required in certain lease agreements. Pursuant to the term of this agreement, ~~$3.4~~$3.3 million of outstanding letters of credit are required to be collateralized by amounts on deposit.

The following table presents information regarding our cash flows for each of the nine months ended June 30, ~~2021~~2022 and ~~2020~~2021 (in thousands):

Our primary source of cash from operating activities is cash collections from our major partners pursuant to our CPAs and FSA. Our primary uses of cash from operating activities are for maintenance costs, personnel costs, operating lease payments, and interest payments.

During our nine months ended June 30, 2022, we had cash flow provided by operating activities of $13.6 million. We had net loss of $67.0 million adjusted for the following significant non-cash items: depreciation and amortization of $61.9 million, stock-based compensation of $2.1 million, net losses on investments in equity securities of $12.6 million, deferred income taxes of $(19.1) million, amortization of deferred credits of $(0.6) million, amortization of debt discount and financing costs and accretion of interest of $8.2 million, and impairment of assets held for sale of $39.5 million. We had a net change of $(24.6) million within other net operating assets and liabilities largely driven by decreases in accrued expenses and other liabilities, deferred revenue, and operating lease liabilities and an increase in accounts receivable, partially offset by an increase in accounts payable during our nine months ended June 30, 2022.

During our nine months ended June 30, 2021, we had cash flow provided by operating activities of $131.2 million. We had net income of $24.1 million adjusted for the following significant non-cash items: depreciation and amortization of $62.1 million, stock-based compensation of $2.4 million, deferred income taxes of $8.0million, amortization of deferred credits of $(2.5) million, amortization of debt discount and ~~issuance~~financing costs and accretion of interest of $8.2 million ~~gain on extinguishment of debt of $(1.0) million,~~, and loss on ~~contract~~lease termination of $4.5 ~~million.~~million.

We also invested a total of ~~$61.7~~$0.2 million ~~stock-based compensation~~in equity securities of ~~$3.5 million, deferred income taxes of $5.9~~million, amortization of deferred credits of $(2.9) million, amortization of debt financing costs and accretion of interest on non-interest bearing subordinated notes of $3.2 million, $0.5 million loss on disposal of assets and provision for obsolete expendable parts of $0.3 million. We had a ~~net change of $3.1 million within other net operating assets and liabilities largely driven by an increase in accrued liability during our nine months ended June 30, 2020.~~

During our nine months ended June 30, 2021, net cash flow used in investing activities totaled $17.0 million. We invested $4.9 million in inventory, $1.6 million in aircraft purchases, ~~and~~ $4.2 million in tools ~~vehicles,~~and other equipment and miscellaneous projects and ~~$6.3~~$6.9 million in ~~net returns and~~ payments onof equipment and other ~~deposits.~~

During our nine months ended June 30, 2020, net cash flow used in investing activities totaled $25.1 million. We invested $11.0 million in spare engines and $3.8 million in aircraft improvements, $8.4 million in inventory, $1.9 million in tools and miscellaneous projects and $13.8 million in lease and equipment deposits offset by ~~$13.9~~$0.6 million from the return of lease and equipment deposits.

Our financing activities generally consist of debt borrowings, principal repayments of debt, payment of debt financing costs, stock repurchases, and proceeds received from issuing common stock under our ESPP.

During our nine months ended June 30, 2022, net cash flow used in financing activities was $39.3 million. We received $35.3 million of proceeds from long-term debt. We made $72.0 million of principal repayments on long-term debt and paid $2.4 million of costs related to debt financing. We received $0.2 million in proceeds from the issuance of common stock under our ESPP and paid $0.4 million to repurchase shares of our common stock.

During our nine months ended June 30, 2021, net cash flow used in financing activities was $33.3 million. We received $195.0 million of proceeds from ~~our~~the Treasury Loan.

We received $0.2 million in proceeds from the issuance of common stock under our ESPP.

During our nine months ended June 30, 2020, net cash flow used in financing activities was $82.6 million. We drew $23.0 million from our $35.0 million working capital draw loan for operational needs. We made $103.7 million of principal repayments on long-term debt during the period. We incurred $1.4 million of costs related to debt financing and $0.5 million of costs related to the repurchase of shares of our common stock.

An off-balance sheet arrangement is any transaction, agreement or other contractual arrangement involving an unconsolidated entity under which a Company has (i) made guarantees, (ii) a retained or a contingent interest in transferred assets, (iii) an obligation under derivative instruments classified as equity or (iv) any obligation arising out of a material variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to the Company, or that engages in leasing, hedging or research and development arrangements with the Company.

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the Securities and Exchange Commission (the "SEC").

A majority of our leased aircraft are leased through trusts formed for the sole purpose of purchasing, financing, and leasing aircraft to us. Because these are single-owner trusts in which we do not participate, we are not at risk for losses and we are not considered the primary beneficiary. We believe that our maximum exposure under the leases are the remaining lease payments and any return condition obligations.

We prepare our condensed consolidated financial statements in accordance with GAAP. In doing so, we must make estimates and assumptions that affect our reported amounts of assets, liabilities, revenue and expenses, as well as related disclosure of contingent assets and liabilities. To the extent that there are material differences between these estimates and actual results, our financial condition or results of operations would be affected. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. We refer to accounting estimates of this type as critical accounting ~~estimates, which we discuss below.~~estimates.

The accompanying discussion and analysis of our financial condition and results of operations is based upon our unaudited condensed consolidated interim financial statements included elsewhere in this Form 10-Q. We believe certain of our accounting estimates and policies are critical to understanding our financial position and results of operations. There have been no material changes to the critical accounting ~~policies~~estimates as explained in Part 1, Item 7 of ~~the 2020~~our Annual Report on Form 10-K for the fiscal year ended September 30, 2021 under the heading "Critical Accounting ~~Policies.~~Estimates."

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 3: "Recent Accounting Pronouncements" to our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

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

Interest Rate Risk. We are subject to market risk associated with changing interest rates on our variable rate long-term debt; the variable interest rates are based on LIBOR. The interest rates applicable to variable rate notes may rise and

increase the amount of interest expense on our variable rate long-term debt. We do not purchase or hold any derivative instruments to protect against the effects of changes in interest rates.

As of June 30, ~~2021,~~2022, we had ~~$521.1~~$471.4 million of variable-rate debt, including current maturities. A hypothetical 50100 basis point change in market interest rates would have affected interest expense by approximately ~~$2.6~~$3.5 million in the nine months ended June 30, ~~2021.~~2022.

As of June 30, ~~2021,~~2022, we had ~~$191.2~~$182.0 million of fixed-rate debt, including current maturities. A hypothetical 50100 basis point change in market interest rates would not impact interest expense or have a material effect on the fair value of our fixed-rate debt instruments as of June 30, ~~2021.~~2022.

On July 27, 2017, the U.K. Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. ~~It is unclear whether new methods~~In December 2020, the administrator of ~~calculating~~ LIBOR proposed to cease publication of certain LIBOR settings after December 2021 and to cease publication of the remainder of the LIBOR settings after June 2023. The majority of our debt arrangements are indexed to one- and three-month LIBOR, which will be established such that it continues to exist after 2021. Similarly, it is not possible to predict whether LIBOR will continue to be viewed as an acceptable market benchmark, what rate or rates may become acceptable alternatives to LIBOR, or what effect these changes in views or alternatives may havesunset on ~~financial markets for LIBOR-linked financial instruments.~~June 30, 2023. While the U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, is considering replacing U.S. dollar LIBOR with a newly created index, calculated based on repurchase agreements backed by Treasury securities, we cannot currently predict whether this index will gain widespread acceptance as a replacement for LIBOR. It is not possible to predict the effect of these changes, other reforms or the establishment of alternative reference rates in the United Kingdom, the United States or elsewhere.

We may in the future pursue amendments to our LIBOR-based debt transactions to provide for a transaction mechanism or other reference rate in anticipation of LIBOR’s discontinuation, but we may not be able to reach agreement with our lenders on any such amendments. As of June 30, ~~2021,~~2022, we had ~~$521.1~~$484.5 million of borrowings based on LIBOR. The replacement of LIBOR with a comparable or successor rate could cause the amount of interest payable on our long-term debt to be different or higher than expected.

Foreign Currency Risk. We have de minimis foreign currency risks related to our station operating expenses denominated in currencies other than the U.S. dollar, primarily the Canadian dollar. Our revenue is U.S. dollar denominated. To date, foreign currency transaction gains and losses have not been material to our financial statements, and we have not had a formal hedging program with respect to foreign currency. A 10% increase or decrease in current exchange rates would not have a material effect on our financial results.

Fuel Price Risk. Unlike other airlines, our ~~capacity purchase~~ agreements largely shelter us from volatility related to fuel prices, which are directly paid and supplied by our major partners.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the ~~Securities~~ Exchange ~~Act of 1934, as amended (the "Exchange Act"))~~Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective.

During the three months ended June 30, 2022, there were no changes in our internal control over financial reporting that materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act).

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

We are subject to two putative class action lawsuits alleging federal securities law violations in connection with our ~~IPO—~~IPO, one in the Superior Court of the State of Arizona and one in U.S. District Court of Arizona. These purported class actions were filed in March and April 2020 against the Company, certain current and former officers and directors, and certain underwriters of the Company’s IPO. The state and federal lawsuits each make the same or similar allegations of violations of the Securities Act of 1933, as amended, for allegedly making materially false and misleading statements in, or omitting material information from, our IPO registration statement.

On March 2, 2022, the parties in the federal lawsuit attended a mediation and reached an agreement in principle to settle all claims asserted in that action for the sum of $5 million, which will be paid by the Company’s directors’ and officers’ insurance carriers. The ~~plaintiffs seek unspecified monetary damages~~settlement is subject to final documentation and ~~other relief.~~preliminary and final approval by the federal court. The motion for preliminary approval was filed on May 6, 2022, and no objections to the settlement were filed by the deadline for such objections. The parties are waiting for the Court to schedule a date for the preliminary approval hearing. If preliminary and final approval is obtained, the claims of all putative class members, whether asserted in the federal or state actions, will be extinguished, unless and only to the extent that a particular class member takes affirmative steps to have its claims excluded.

In addition, we are subject to certain legal actions which we consider routine to our business activities. As of June 30, ~~2021,~~2022, our management believed ~~after consultation with legal counsel, that~~ the ultimate ~~outcome~~outcomes of ~~the two putative class action lawsuits and such~~ other routine legal matters are not likely to have a material adverse effect on our financial position, liquidity or results of operations.

We refer you to documents filed by us with the SEC, specifically "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended September 30, ~~2020,~~2021, which identify important risk factors that could materially affect our business, financial condition and future results. We also refer you to the factors and cautionary language set forth in the section entitled "Cautionary Statements Regarding Forward-looking Statements" of this Quarterly Report on Form 10-Q. This Quarterly Report on Form 10-Q, including the accompanying condensed consolidated financial statements and related notes, should be read in conjunction with such risks and other factors for a full understanding of our operations and financial condition. The risks described in our Annual Report on Form 10-K for the fiscal year ended September 30, ~~2020~~2021 and herein are not the only risks facing us. 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, or operating results.Except as set forth below, there have been no material changes to the risk factors previously disclosed in our 2021 Form 10-K.

The reduced utilization levels of our aircraft under our agreements with our major partner, to the extent they continue, would have a material adverse impact on our results of operations and financial condition.

Historically, our major partners have utilized our flight operations at levels at or near the maximum capacity of our fleet allocations under the applicable CPA agreements. As previously reported, we operated at significantly lower block hours during fiscal 2020 and fiscal 2021 due to the COVID pandemic, though we experienced a recovery in demand for air travel during the second half of fiscal 2021, which has continued into fiscal 2022.

Notwithstanding the increase in demand for air travel, in recent periods our high level of pilot attrition and pilot training output limitations has resulted in a reduction of our block hours flown. If we continue to experience pilot attrition above historic levels, we may experience further reductions in the block hours flown under our CPAs by our major partners, and we may not be able to maintain operating efficiencies previously obtained, each of which would negatively impact our operating results and financial condition. There can be no assurance that we will be able to adequately address the pilot attrition issues or that our major partners will increase the utilization of our aircraft to historical levels in future periods if we do experience an improvement in pilot attrition. If pilot attrition persists, we may experience additional declines in utilization levels, which would in turn have a material adverse impact on our financial condition and results of operations.

If the supply of pilots to the airline industry remains constrained and pilot attrition continues to exceed historical levels, our results of operations and financial condition would be negatively impacted.

Our operations continue to be negatively impacted by the pilot shortages that have plagued the airline industry as whole, and by the associated pilot attrition that we believe has disproportionately impacted regional airlines, including us. Our pilots continue to be recruited by other carriers, primarily the major carriers and heavy equipment cargo operators, which generally offer higher salaries and more extensive benefit programs. The magnitude of this attrition in fiscal 2022

has created significant backlogs in training, further exacerbating an already challenging environment. These events have had, and continue to have, a negative impact on pilot scheduling, work hours, and the number of pilots required to support our operations.

There has been significant press coverage over the past several months regarding the issues stemming from the pilot shortages (namely flight cancellations and delays by the major carriers), with no airline being immune to the issues created by the pilot shortage or the associated negative press. As we have in the past, we are taking important steps to further attract, hire and retain qualified pilots, including the ongoing implementation of significant pilot wage and bonus increases, pilot retention initiatives, increases in training capacity, and other cost efficiency initiatives. Notwithstanding these steps, our current rate of hiring has not kept pace with attrition. As such, even with increases in training capacity we are not currently able to hire qualified pilots at a rate sufficient to fill all available classroom training spaces, which in turn has negatively impacted the number of pilots available for scheduled operations. No assurance can be given that the measures we are currently taking or may take in the future will enable us to attract, hire and train pilots at a rate necessary to support our operations.

Our ability to attract, hire and retain qualified pilots has been, and continues to be, negatively impacted by the status of our collective bargaining agreement with ALPA, which became amendable in July 2021 and remains under negotiation. Recent efforts to reach a mutually acceptable deal have not resulted in an agreement between the parties. Absent certainty surrounding the terms and conditions of our future collective bargaining agreement with ALPA, we have experienced, and are likely to continue to experience, challenges attracting, hiring, and retaining pilots. These challenges, if they persist, will likely negatively impact our financial condition, results of operations, and relationship with our major partners.

In addition to the foregoing, our pilot premium wage and bonus initiatives have substantially increased our labor costs and continue to negatively impact our operations and financial condition. Other regional air carriers have implemented similar measures, which has only served to increase the competition for qualified pilots and the costs associated with hiring pilots. We expect these increased costs, to the extent they persist, to materially and adversely impact our financial condition and results of operations in future periods.

If the high levels of pilot attrition persist and we are unable to attract, hire and retain pilots at a rate sufficient to support required utilization levels under our CPAs, we may be required to issue credits or provide offsets to our major partners, as we have done in the past, and to reduced flight schedules with our major partners, which has resulted in and may continue to result in monetary performance penalties under our CPAs, as well as give rise to the ability of our major partners in certain circumstances to elect to remove aircraft from the scope of our CPAs. Should any of these events arise in the future, they could have a material and adverse impact on our financial condition and results of operations.

The failure to pay at maturity the amounts outstanding under our CIT Revolving Credit Facility or to timely refinance this indebtedness would result in a default thereunder, which would also trigger cross-default clauses under our other indebtedness and give such lenders the right to accelerate the payment of such obligations.

Our CIT Revolving Credit Facility currently matures on December 31, 2022. No assurance can be given that we will have sufficient liquidity to pay at maturity the amounts outstanding thereunder (approximately $15.0 million at June 30, 2022) or that we will be able to timely refinance such indebtedness if we are unable or do not intend to repay the same. Failure to pay at maturity the amounts outstanding thereunder or to otherwise timely refinance this indebtedness would result in an event of default under the Credit Facility, which would in turn entitle the lenders thereunder to exercise all available remedies, including seeking repayment from the guarantor of such indebtedness, Mesa Air, foreclosing on the assets securing such indebtedness (i.e., certain engines, spare parts, and related collateral), or requiring the borrowers thereunder to cash collateralize all outstanding letter of credit liabilities in an amount equal to 105% of such liabilities. A default under the CIT Revolving Credit Facility would also trigger cross-default clauses under our other indebtedness and give the lenders thereunder the right to exercise all available remedies under such loan agreements, including, to the extent they so elect, the acceleration of such indebtedness. We currently do not have sufficient liquidity to repay all of our outstanding debt in full if such debt were accelerated. If we are unable to pay our debts as they come due, or obtain waivers for such payments, our secured lenders could foreclose on any assets securing such debt. These events would materially adversely affect our business, results of operations and financial condition.

The Company repurchased ~~139,896~~132,151 shares of its common stock for ~~$1.4~~$0.4 million to cover the income tax obligation on vested employee equity awards and warrant conversions during the nine months ended June 30, ~~2021.~~2022.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
