Investors and others should note that we may announce material business and financial information to our investors using our investor relations website (http://investor.mesa-air.com/), SEC filings, webcasts, press releases, and conference calls. We use these mediums, including our website, to communicate with our members and public about our company, our products, and other issues. It is possible that the information that we make available may be deemed to be material information. We therefore encourage investors and others interested in our company to review the information that we make available on our website.

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact contained in this Quarterly Report on Form 10-Q, including statements regarding our future results of operations and financial position, business strategy and plans, and objectives of management for future operations, are forward-looking statements. These statements involve known and unknown risks, uncertainties, and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as "may", "should", "expects", "might", "plans", "anticipates", "could", "intends", "target", "projects", "contemplates", "believes", "estimates", "predicts", "potential", "seek", "would", "continue", or the negative of these terms or other similar expressions. The forward-looking statements in this Quarterly Report on Form 10-Q are only predictions. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our business, financial condition and results of operations. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. These forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are subject to a number of risks, uncertainties and assumptions described in the "Risk Factors" section and elsewhere in this Quarterly Report on Form 10-Q. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Some of the key factors that could cause actual results to differ from our expectations include:

While we may elect to update these forward-looking statements at some point in the future, whether as a result of any new information, future events, or otherwise, we have no current intention of doing so except to the extent required by applicable law.

Headquartered in Phoenix, Arizona, Mesa Air Group, Inc. ("Mesa" or the "Company") is a holding company whose principal subsidiary, Mesa Airlines, Inc. ("Mesa Airlines"), operates as a regional air carrier providing scheduled flight service to ~~135~~66 cities in 3929 states, the District of Columbia ~~Canada, Mexico, Cuba,~~ and ~~the Bahamas.~~Mexico. As of ~~March 31,~~June 30, 2020, Mesa operated a fleet of 145 aircraft with approximately ~~662~~175 daily departures and ~~3,600~~3,400 employees. Mesa operates all of its flights as either American Eagle or United Express flights pursuant to the terms of the capacity purchase agreements entered into with American Airlines, Inc. (“American”) and United Airlines, Inc. (“United”).

The financial arrangements between the Company and its major airline partners involve a revenue-guarantee arrangement (i.e., a "capacity purchase agreement") whereby the major airline pays a monthly guaranteed amount 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 flown and reimbursement of certain direct operating expenses in exchange for providing regional flying. The major airline partners also pay certain expenses directly to suppliers, such as fuel, ground operations and landing fees. Under the terms of these capacity purchase agreements, the major airline controls route selection, pricing and seat inventories, thereby reducing the Company's exposure to fluctuations in passenger traffic, fare levels, and fuel prices.

The unprecedented and rapid spread of COVID-19 and the related travel restrictions and social distancing measures implemented throughout the world have significantly reduced demand for air travel. The length and severity of the reduction in demand due to the pandemic isremains uncertain. This reduction in demand has had an unprecedented and materially adverse impact on our revenues and financial position. ~~We expect the adverse impact to grow in the June 2020 quarter. While we are planning for a modest demand recovery beginning in the September 2020 quarter, the~~The exact timing and pace of ~~the~~a recovery in demand is uncertain given the significant impact of the pandemic on the overall U.S. and global economy. Our forecasted expense management and liquidity measures may be modified as we clarify the demand recovery timing. Since a portion of ~~our revenue is fixed due to~~ the ~~structure of~~consideration we receive under our capacity purchase agreements is fixed, the impact to Mesa will be partially mitigated or offset. In addition, we have limited exposure to fluctuations in passenger traffic, ticket and fuel prices. While the fixed ~~revenue~~contract consideration remains mostly unchanged, the variable revenue based on number of block hours ~~has been~~was significantly reduced beginning in the last few weeks in March and wein the June 2020 quarter. We may experience further ~~reductions. The initiatives and measures put~~reductions in ~~place to limit the spread of the virus has and will continue to have a materially adverse impact on our business.~~subsequent quarters. The Company further reports that, beginning in March 2020, it ~~has~~ experienced a material decline in demand in block hours from both of its major airline partners, American and United Airlines, Inc. (“United” and together with American, the “Partners”) resulting from the spread of the COVID-19 virus. As a result of this decline in demand and the subsequent capacity reductions by the Company’s Partners, the Company operated ~~10,297~~at significantly lower block hours in ~~April~~the June 2020 quarter. While there has been a ~~72.4% drop from April 2019. The~~modest demand recovery, the Company ~~also~~ anticipates similar schedule reductions will likely continue into the ~~second~~fourth quarter of 2020 and may continue throughout the remainder of calendar year 2020 and into 2021.

In response to ~~these developments, our major partners and~~ the ~~Company~~recent COVID-19 pandemic, we have implemented various measures to ~~focus on~~protect our employees as they continue to provide safe and reliable transportation to the passengers of American and United. The safety of our ~~customers~~employees and ~~employees, while at the same time seeking~~passengers remains our primary focus and, to ~~mitigate the impact on our financial position and operations. These~~that end, measures that we have taken include but are not limited ~~to, the following:~~

•Increasing the scope of cleaning and sanitization of aircraft both while remaining overnight and on turn flights. Both on our own, and in coordination with our codeshare partners, we have taken steps to ensure that high touch areas used by both employees and customers are routinely and comprehensively cleaned and disinfected to prevent transmission of the virus on surfaces. To assist our crewmembers in keeping the aircraft clean and disinfected, we have increased the supply of sanitizing wipes onboard.

•In coordination with our codeshare partners, social distancing methods onboard have been implemented comprised of seat-blocking to encourage additional space between passengers and our Inflight teams help to encourage passenger spacing onb~~oard.~~

•We have provided, and continue to resupply, our employees with Personal Protective Equipment (PPE) consisting of gloves and face coverings for use whenever social distancing cannot be maintained or when working with ourto:

customers. In addition, at various locations, we have coordinated with our codeshare partners to conduct temperature checks of employees reporting for duty. In those locations where this is not yet established, crewmembers have been directed to self-monitor their temperature before reporting for duty and twice daily.

•Based on recommendations from the Centers for Disease Control (CDC), we have increased facility cleaning and disinfection protocols at all of our facilities and have implemented social distancing measures includ~~ing telecommuting for many of our Corporate personnel and methods to increase physical distance between workers who remain working at our Corporate facilities~~

•~~Established protocols for employees who are positive for, or suspected of, COVID-19 to ensure t~~hat they have the necessary time off. Additionally, we have implemented protocols to ensure that proper notification is made to any affected employees. Protocols have also been put into place for the immediate disinfection of any affected aircraft above and beyond routine cleaning and disinfection protocols.

Expense Management. With the reduction in revenue, we have, and will continue to implement cost saving initiatives, including:

Balance Sheet, Cash Flow and Liquidity. As of ~~March 31,~~June 30, 2020, our cash and cash equivalents balance was ~~$52.4~~$64.9 million. We have taken the following actions to increase liquidity and strengthen our financial position.

As of ~~March 31,~~June 30, 2020, the Company operated 5954 CRJ-900 aircraft for American under our American Capacity Purchase Agreement. In exchange for providing flight services under our American Capacity Purchase Agreement, 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 and controllable completion percentages. American also reimburses us for certain costs on an actual basis, including passenger liability and hull insurance and aircraft property taxes, all as set forth in our American Capacity Purchase Agreement. 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.

Our American Capacity Purchase Agreement establishes utilization credits which are required to be paid if the Company does not operate at minimum levels of flight operations. In prior periods, the FAA Qualification Standards (as defined below) have negatively impacted our ability to hire pilots at a rate sufficient to support required utilization levels, and, as a result, we have issued credits to American pursuant to the terms of our American Capacity Purchase Agreement.

Our American Capacity Purchase Agreement will terminate with respect to different tranches of aircraft between 2021 and 2025, unless otherwise extended or amended. As of the date of this filing, we remain in discussions with American regarding the terms of extending the 3031 aircraft that are due to expire in 2021, ~~and~~ the 1916 aircraft that are due to expire in 2022, and the 7 aircraft that expire in 2025. Our American Capacity Purchase Agreement is subject to termination prior to that date, subject to our right to cure, in various circumstances including:

In the event that American has the right to terminate our American Capacity Purchase Agreement, American may, in lieu of termination, withdraw up to an aggregate of 14 aircraft from service under our American Capacity Purchase Agreement. Upon any such withdrawal, American's payments to us would be correspondingly reduced by the number of withdrawn aircraft.

On January 31, 2019, the Company entered into an amendment to the American Capacity Purchase Agreement, the terms of which provide for new and revised operational performance metrics, the Company's right to earn additional incentive compensation based on the achievement of such metrics, and the right of American to permanently withdraw up to six (6) aircraft in the event the Company fails to meet such new/revised performance metrics. Under the terms of such amendment the Company agreed, effective April 2, 2019, to convert two (2) aircraft to be utilized by the Company as operational spares in the Company's sole discretion throughout its system. In July 2019, American exercised its right to permanently withdraw ~~two~~2 (2) aircraft from the American Capacity Purchase Agreement due to the Company's failure to meet certain performance metrics. The aircraft were removed on November 2, 2019. On November 25, 2019, the Company amended its agreement with American Airlines. The Company did not meet certain performance metrics during the then most recent measurement period, which would have allowed American to remove ~~two~~2 additional aircraft from the capacity purchase agreement. American had agreed to defer the right to remove these two aircraft but subsequently elected to remove ~~one~~1 of the two previously deferred aircraft, effective January 2, 2020. As of January 2, 2020, American had removed ~~three~~3 (3) of the six (6) aircraft under the January 31^st amendment.

On April 3, 2020, the Company received a new withdrawal notice from American seeking to permanently withdraw ~~three~~3 aircraft from the American Capacity Purchase Agreement. Two of the aircraft ~~will be~~were withdrawn effective May 19, 2020 and the third aircraft ~~will be~~was withdrawn effective June 1, 2020. The withdrawal of these three aircraft stems from withdrawal rights that American previously asserted were triggered in September 2019 and November 2019. At such time, American refrained from exercising such withdrawal rights, however, reserved the right to withdraw the three aircraft at a later date under certain circumstances. In light of the rapid grounding of aircraft caused by the COVID-19 virus, the overall reduction in demand for air travel, and the need to reduce capacity, American elected to remove such aircraft ~~now.~~in early June.

~~Following~~On June 11, 2020, the ~~removal~~Company entered into the Twenty-First Amendment to The American Capacity Purchase Agreement effective April 1, 2020. The amendments include (i) the permanent withdrawal of 2 (2) additional aircraft from the American Capacity Purchase Agreement, effective June 15, 2020, with such aircraft included in the tranche of aircraft American has the right to ratably remove commencing January 1, 2021 in exchange for American paying the full cost of the ~~three~~ aircraft ~~referenced above,~~for the ~~Company will continue~~same period and (ii) the addition of utilization-based credits, entitling American to ~~operate 56 CRJ-900~~payment credits for the period April 1, 2020 through September 30, 2020, based upon the achievement of agreed upon aircraft utilization thresholds, subject to Mesa’s receipt of previously approved funds under the ~~American CPA.~~ CARES Act. The impact of the contract modification was not material to the three or nine months ended June 30, 2020.

As of ~~March 31,~~June 30, 2020, the Company operated 20 CRJ-700 and 60 E-175 aircraft for United under our United Capacity Purchase Agreement.In exchange for providing the flight services under our United Capacity Purchase Agreement, 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. ~~We also receive a minimum profit margin based upon our operational performance.~~ Under our United Capacity Purchase Agreement, United owns 42 of the 60 E-175 aircraft and leases them to us at nominal amounts. United 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 42 E-175 aircraft owned by United. Our United Capacity Purchase Agreement permits United, subject to certain conditions, including the payment of certain costs tied to aircraft type, to terminate the agreement in its discretion, or remove aircraft from service, by giving us notice of 90 days or more. If United elects to terminate our United Capacity Purchase Agreement in its entirety or permanently remove select aircraft from service, we are permitted to return any of the affected E-175 aircraft leased from United at no cost to us. In addition, if United removes any of our 18 owned E-175 aircraft from service at its direction, United would remain obligated to assume the aircraft ownership and associated debt with respect to such aircraft through the end of the term of the agreement.

On November 26, 2019, we amended and restated our United Capacity Purchase Agreement to, among other things, incorporate the terms of the 1114 prior amendments to that Agreement and to extend the term thereof through the addition of twenty (20) new Embraer E175LL aircraft to the scope of such Agreement. These new aircraft will be financed and owned by us and operated for a period of twelve (12) years from the in-service date. Deliveries of the new E175LL aircraft ~~are~~were scheduled to begin in May 2020 and be completed by December 31, 2020. In March 2020, the deliveries of the new E175LL aircraft were negotiated between United and Embraer to begin in September 2020 and be completed by the quarter ended June 30, 2021. Commencing five (5) years after the actual in-service date, United has the right to remove the E175LL aircraft from service by giving us notice of 90 days or more, subject to certain conditions, including the payment of certain wind-down expenses plus, if removed prior to the ten (10) year anniversary of the in-service date, certain accelerated margin payments.

In addition to adding the 20 new E175LL aircraft to the amended and restated United Capacity Purchase Agreement, we extended the term of our 42 E-175 aircraft leased from United for an additional five (5) years, which now expire between 2024 and 2028. As part of the amended and restated United Capacity Purchase Agreement, we agreed to lease our ~~twenty (20)~~ CRJ-700 aircraft to another United Express service provider for a term of seven (7) years. We will continue to operate such aircraft until they are ~~transitioned.~~transitioned to the new service provider. United has a right to purchase the ~~CRJ 700~~CRJ-700 aircraft at the then fair market value. In addition, we own 18 E-175 aircraft that expire in 2028.

Our United Capacity Purchase Agreement is subject to early termination under various circumstances noted above and including:

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 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.

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, 2019 included in the Company's Annual Report on Form 10-K for the year ended September 30, 2019 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,"~~Act") and may remain an emerging growth company until the last day of its fiscal year following the fifth anniversary of ~~the~~its August 2018 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.

Effective October 1, 2019, we have adopted ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02") which provides guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for substantially all leases, with the exception of short-term leases. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the statement of income. We determine if an arrangement is a lease at inception. Our current lease activities are recorded in operating lease right-of-use (“ROU”) assets, current maturities of operating lease and noncurrent operating lease liabilities in the condensed consolidated balance sheets. Finance leases are included in property and equipment, net, current portion of long-term debt and financing leases, long-term debt and financing leases, excluding current portion.

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. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Variable lease payments are not included in the calculation of the right-of-use assets and lease liability due to uncertainty of the payment amount and are recorded as lease expense in the period incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

As a lessor, for our aircraft operated under our capacity purchase agreements, we have historically accounted for the non-lease component under ASC 606 and have historically accounted for the lease component under ASC 840. Under the available practical expedient, we have elected to account for the lease and non-lease components as a single component for all classes of underlying assets. As the predominant component of the combined components are the flights services, the leases are being accounted for entirely under ASC 606. As a lessee, we elected a short-term lease exception policy on all classes of underlying assets, permitting us to not apply the recognition requirements of this standard to short-term leases (i.e. leases with terms of 12 months or less).

As a lessor, our capacity purchase agreements identify the "right of use" of a specific type and number of aircraft over a stated period-of-time. A portion of the compensation in the capacity purchase agreements are designed to reimburse the Company for certain aircraft ownership costs of these aircraft. 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.

In addition to the aircraft we ~~receive~~lease from United under our United Capacity Purchase Agreement, approximately 12% 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 airline 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 will be written off.

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

Contract liabilities consist of deferred credits for cost reimbursements from major airline partners related to aircraft modifications associated with capacity purchase agreements and pilot training. The deferred credits are recognized over time depicting the pattern of 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 to other accrued expenses and non-current deferred credits in the condensed consolidated balance sheets. The Company's total current and non-current deferred credit balances at ~~March 31,~~June 30, 2020 and September 30, 2019 are ~~$10.2~~$9.4 million and $12.1 million, respectively. The Company recognized $0.9 million and ~~$1.4~~$1.3 million of the deferred credits to revenue in the condensed consolidated statements of operations during the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively, and ~~$2.0~~$2.9 million and ~~$2.6~~$3.8 million during the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019, respectively.

The Company recognizes assets from the costs incurred to fulfill a contract including aircraft painting and reconfiguration and flight service personnel training costs. These costs are amortized based on the pattern of transfer of the services in relation to flight hours over the term of the contract. Contract assets are recorded as other assets in the condensed consolidated balance sheets. The Company's contract assets balances at ~~March 31,~~June 30, 2020 and September 30, 2019 are ~~$2.8~~$2.4 million and $3.9 million, respectively. Contract cost amortization was ~~$0.4~~$0.3 million and ~~$0.5~~$0.6 million for the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively, and ~~$0.9~~$1.2 million and ~~$1.0~~$1.8 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019, respectively.

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 operates under a Federal Aviation Administration ("FAA") approved continuous inspection and maintenance program. The Company uses the direct expense method of accounting for its maintenance of regional jet engine overhauls, airframe, landing gear, and normal recurring maintenance wherein the Company recognizes the expense when the maintenance work is completed, or over the repair period, if materially different. Our maintenance policy is determined by fleet when major maintenance is incurred. For leased aircraft, the Company is subject to lease return provisions that require a minimum portion of the "life" of an overhaul be remaining on the engine at the lease return date. The Company estimates the cost of maintenance lease return obligations and accrues such costs over the remaining lease term when the expense is probable and can be reasonably estimated.

Under the Company's aircraft operating lease agreements and FAA operating regulations, it is obligated to perform all required maintenance activities on its fleet, including component repairs, scheduled air frame checks and major engine restoration events. The Company estimates the timing of the next major maintenance event based on assumptions including estimated usage, FAA-mandated maintenance intervals and average removal times as recommended by the manufacturer. The timing and the cost of maintenance are based on estimates, which can be impacted by changes in utilization of its aircraft, changes in government regulations and suggested manufacturer maintenance intervals. Major maintenance events consist of overhauls to major components.

Engine overhaul expense totaled ~~$14.5~~$3.2 million and ~~$5.2~~$11.4 million for the three months ended ~~March 31,~~June 30, 2020, and 2019, respectively, of which ~~$0.7~~$0.4 million and ~~$(0.4)~~$1.9 million, respectively, was pass-through expense. Engine overhaul expense totaled ~~$25.1~~$28.3 million and ~~$9.4~~$20.8 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2020, and 2019, respectively, of which ~~$2.6~~$3.0 million and ~~$1.2~~$3.0 million, respectively, was pass-through expense. Airframe C-check expense totaled ~~$10.5~~$2.9 million and ~~$4.7~~$4.4 million for the three months ended ~~March 31,~~June 30, 2020, and 2019, respectively, of which ~~$3.9~~$0.8 million and $0.0 million, respectively, was pass-through expense. Airframe C-check expense totaled ~~$17.8~~$20.6 million and ~~$6.2~~$10.6 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2020, and 2019, respectively, of which ~~$5.1~~$5.9 million and $0.0 million, respectively, was pass-through expense.

The Company recognizes contract revenue when the service is provided under its capacity purchase agreements. Under the capacity purchase agreements, our airline partners generally pay for each departure, flight hour (measured from takeoff to landing, excluding taxi time) or block hour (measured from takeoff to landing, including taxi time) incurred, and an amount per aircraft in service each month with additional incentives based on flight completion and on-time performance. The major airline partners also directly pay for or reimburses the Company for certain direct expenses incurred under the capacity purchase agreement, such as fuel and airport landing fees. The Company’s performance obligation is met when each flight is completed and revenue is recognized and reflected in contract revenue. The directly reimbursed expenses, earned as flights are completed over the agreement term, are recognized and reflected in pass-through revenue.

During the quarter ended June 30, 2020, the Company completed a significantly lower than normal number of flights due to the impact of COVID-19. Since the revenue recognition is based on the number of flights completed, the fixed amount of cash received exceeded the revenue recognized based on the number of flights completed during the quarter. Under US GAAP, the fixed monthly payments are recognized as revenue ratably based on completed flights over the contract term. The Company deferred $16.0 million of revenue in the quarter ended June 30, 2020. The current portion of $3.8 million of deferred revenue is recorded as a part of other accrued expenses and long-term portion of $12.2 million is recorded as deferred revenue on the balance sheet. This deferred revenue will be recognized when flights are completed over the remaining contract term.

The deferred revenue balance as of June 30, 2020 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 compensation under its capacity purchase agreements with American and United is designed to reimburse the Company for certain aircraft ownership costs. The Company has concluded that a component of its revenue 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.

The lease revenue associated with the Company's capacity purchase agreements is accounted for as an operating lease and is reflected as contract revenue on the Company's condensed consolidated statements of operations. The Company recognized $52.0 million and $54.5 million of lease revenue for the three months ended June 30, 2020 and 2019, respectively, and $157.7 million and $164.5 million of lease revenue for the nine months ended June 30, 2020 and 2019, respectively. The Company has not separately stated aircraft rental income and aircraft rental expense in the condensed consolidated statements of operations because the use of the aircraft is not a separate activity of the total service provided under our capacity purchase agreements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (“ASU2020-04”). 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 London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued. Optional expedients can be applied from March 12, 2020 through December 31, 2022. We are currently evaluating the impact that the new guidance will have on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"). This ASU introduces a new accounting model known as Credit Expected Credit Losses (“CECL”). CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. The CECL model utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses for receivables at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. This model replaces the multiple existing impairment models in current GAAP, which generally require that a loss be incurred before it is recognized. The new standard will also apply to receivables arising from revenue transactions such as contract assets and accounts receivables. There are other provisions within the standard affecting how impairments of other financial assets may be recorded and presented, as well as expanded disclosures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which provides guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for substantially all leases, with the exception of short-term leases. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the statement of income. The Company adopted Topic 842 effective October 1, 2019 and elected the package of transition practical expedients for expired or existing contracts, which does not require reassessment of: (1) whether any of the Company’s contracts are or contain leases, (2) lease classification and (3) initial direct costs. In July 2018, the FASB issued ASU No. 2018-11, "Targeted Improvements - Leases (Topic 842)." The Company did not elect the hindsight practical expedient. This update provides an optional transition method that allows entities to elect to apply the standard using the modified retrospective approach at its effective date, versus recasting the prior years presented. If this adoption method is elected, an entity would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the year of adoption. The Company elected this adoption method on October 1, 2019.There was no0 adjustment to retained earnings.

Additionally, the Company’s adoption of Topic 842 did not have a significant impact on the recognition, measurement or presentation of lease revenue and lease expenses within the consolidated statements of operations or the consolidated statements of cash flows. The Company’s adoption of Topic 842 did not have a material impact on the timing or amount of the Company’s lease revenue as a lessor. The Company’s prepaid aircraft rents, accrued aircraft rents and deferred rent credits that were separately stated in the Company’s September 30, 2019 balance sheet have been classified as a component of the Company’s right-of-use assets effective October 1, 2019. The consolidated financial statements for the three months ended December 31, 2019 are presented under the new standard, while comparative years presented are not adjusted and continue to be reported in accordance with the Company’s historical accounting policy. See Note ~~14,~~15, "Leases, Commitments and Contingencies," for more information.

In July 2018, the FASB issued ASU 2018-09, Codification Improvements, which contains amendments that affect a wide variety of Topics in the Codification, including amendment to Subtopic 718-40, Compensation-Stock Compensation-Income Taxes, that clarifies the timing of when an entity should recognize excess tax benefits. We adopted this standard on October 1, 2019 and it did not have a material impact on our condensed consolidated financial statements.

At ~~March 31,~~June 30, 2020, the Company had capacity purchase agreements with American and United. All of the Company's condensed consolidated revenue for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019 and accounts receivable at ~~March 31,~~June 30, 2020 and September 30, 2019 was derived from these agreements. The terms of both the American and United capacity purchase agreements are not aligned with the lease obligations on the aircraft performing services under such agreements.

Amounts billed by the Company under capacity purchase agreements are subject to the Company's interpretation of the applicable capacity purchase agreement and are subject to audit by the Company's major airline partners. Periodically, the Company's major airline 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 airline partner. As such, the Company periodically reviews amounts past due and records a reserve for amounts estimated to be uncollectible. The allowance for doubtful accounts was ~~$2.8~~$5.4 million and $1.0 million at ~~March 31,~~June 30, 2020 and September 30, 2019, respectively. If the Company's ability to collect these receivables and the financial viability of its partners is materially different than estimated, the Company's estimate of the allowance could be materially impacted.

American accounted for approximately ~~51%~~60% and ~~55%~~53% of the Company's total revenue for the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively, and 5153 % and 54 % for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and ~~2019.~~2019, respectively. United accounted for approximately ~~49%~~40% and ~~45%~~47% of the Company's revenue for the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively, and ~~49%~~47% and 46% for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and ~~2019.~~2019, respectively. A termination of either the American or the United capacity purchase agreement would have a material adverse effect on the Company's business prospects, financial condition, results of operations, and cash flows.

The Company monitors for any indicators of impairment of the intangible assets. When certain conditions or changes in the economic situation such as the current environment brought by COVID-19 exist, the assets may be impaired and the carrying amount of the assets exceed its fair value. ~~The assets need to be tested for recoverability of carrying amount.~~

We determined that our reduced flying schedules and cash flow projections as a result of the COVID-19 pandemic indicate that an impairment loss may have been incurred. Therefore, we quantitatively assessed whether it was more likely than not that the intangible assets we hold have been impaired as of ~~March 31,~~June 30, 2020. We reviewed our previous forecasts and assumptions based on our current projections that are subject to various risks and uncertainties, including: (1) forecasted revenues, expenses and cash flows, including the duration and extent of impact to our business from the COVID-19 pandemic, (2) current discount rates, (3) changes to the regulatory environment and (4) the nature and amount of government support that will be provided.

Based on our carrying amount recoverability test, we have concluded that our finite-lived intangible assets are not impaired as of ~~March 31,~~June 30, 2020. Given the uncertain future amid COVID-19, we will conduct additional tests in 3the 4^rdth quarter of 2020.

Information about the intangible assets of the Company at ~~March 31,~~June 30, 2020 and September 30, 2019, were as follows (in thousands):

The Company monitors for any indicators of impairment of the long-lived fixed assets. When certain conditions or changes in the economic situation such as the current environment brought by COVID-19 exist, the assets may be impaired and the carrying amount of the assets exceed its fair value. The assets need to be tested for recoverability of carrying amount.

To determine whether impairments exist, we group assets at the Capacity Purchase Agreement and fleet-type level (i.e., the lowest level for which there are identifiable cash flows) and then estimate future cash flows based on projections of capacity purchase arrangements, block hours, maintenance events, labor costs and other relevant factors. Due to our reduced flying schedules and projections of future cash flows, we evaluated each of our fleets to determine if any of the fleets are impaired.

Based on our carrying amount recoverability test, we have concluded that no fleet was impaired as of ~~March 31,~~June 30, 2020 as the future cash flows exceeded the carrying value of our long-lived fixed assets. Given the uncertain future amid COVID-19, we will conduct additional tests in 34^rdth quarter 2020.

Depreciation expense totaled approximately ~~$20.1~~$20.2 million and ~~$18.8~~$19.3 million for the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively, and ~~$40.3~~$60.5 million and ~~$36.9~~$56.2 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019, respectively.

Prior to the Company’s adoption of Topic 842 on October 1, 2019, the Company recorded amortization of the unfavorable lease liability of approximately ~~$1.5~~$1.4 million for the three months ended ~~March 31,~~June 30, 2019 and $4.5 million for the nine months ended June 30, 2019 as a reduction to lease

expense. Upon the Company’s adoption of Topic 842, the unfavorable lease liability is now included in its ROU asset balance and amortized therein.

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 debt agreements are not traded on an active market. The Company has determined the estimated fair value of its 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 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 long-term debt, including current maturities, were as follows (in millions):

Long-term debt as of ~~March 31,~~June 30, 2020 and September 30, 2019, consisted of the following (in thousands):

The net book value of collateralized aircraft and equipment as of ~~March 31,~~June 30, 2020 was ~~$1,168.0~~$1,114.0 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. At ~~March 31,~~June 30, 2020 Mesa has $181.8 million of equipment notes outstanding issued under the EETC financing included in long-term debt on 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 evaluated whether the pass-through trust formed for its EETC financing is a Variable Interest Entity ("VIE") and required to be consolidated. The pass-through trust was determined to be a VIE, however, the Company has determined that it does not have a variable interest in the pass-through trust, and therefore, has not consolidated the pass-through trust with its financial statements.

On January 28, 2019, the Company entered into a Term Loan Agreement (the "Term Loan") pursuant to which the lenders thereunder committed to lend to the Company term loans in the aggregate principal amount of $91.2 million. Borrowings under the Term Loan bear interest at LIBOR plus 3.10%. This interest rate is significantly lower than the interest rate under the Company's Spare Engine Facility (defined below), which the Term Loan refinanced and replaced. The Spare Engine Facility accrued interest at LIBOR plus 7.25%. The Term Loan has a term of five years, with principal and interest payments due monthly over the term of the loan in accordance with an amortization schedule. The Company recorded a loss on extinguishment of debt of $3.6 million, due to a $1.9 million write-off of financing fees and $1.7 million in prepayment penalties, in connection with the repayment of the Spare Engine Facility.

On June 14, 2019, the Company completed the purchase of ~~ten~~10 CRJ-700 aircraft, which were previously leased under the aircraft lease facility with Wells Fargo Bank Northwest, National Association, as owner trustee and lessor (the “GECAS Lease Facility”), for $70.0 million. The Company financed the aircraft purchase with $70.0 million in new debt. The notes payable of $70.0 million require monthly payments of principal and interest through fiscal 2023 bearing interest at LIBOR plus 5.0%. The Company recorded non-cash lease termination expense of $9.5 million in connection with the lease buyout.

On September 25, 2019, the Company extended the term on ~~their~~its $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 ~~5.24%~~3.75%. In the 2^nd quarter of 2020, $23.0 million was drawn to cover operational needs.

On September 27, 2019, the Company financed certain flight equipment with $8.0 million in new debt. ~~The~~This debt ~~of $8.0 million require~~requires monthly payments of principal and interest through fiscal 2023 ~~bearing~~and bears interest at Libor plus 5.0%.

On April 9, 2020, Export Development Canada (“EDC”) provided Mesa Air with deferral of principle payments due and owing beginning on March 19, 2020 to and including September 30, 2020 totaling $28.0 million. All Deferred Payments shall be due in a lump sum payment on September 30, 2020 per the letter agreement dated April 9, 2020. The company performed the debt modification accounting assessment and treated as a modification with immaterial issuance costs capitalized.

In June 2020, the company amended their RASPRO aircraft lease agreement to defer $4.0 million of a lease payment otherwise due in June 2020. Per the amended agreement dated June 5,2020, the company is to pay this amount over the period of September 2021 through March 2024. The company made the accounting election available for COVID-19 related concession provided by a lessor. This event is not a lease modification and requires no changes to current accounting treatment.

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

Basic income per common share is computed by dividing net income 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 considered to be anti-dilutive under the treasury stock method were 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 no0 anti-dilutive shares relating to restricted stock and exercise of warrants that were excluded from the calculation of diluted loss per share for the three and ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019.

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. Certain persons who are not U.S. citizens ~~currently hold~~held outstanding warrants to purchase shares of the Company's common stock. The warrants ~~are~~were exercisable only 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~~could be ~~converted to common stock~~exercised upon the 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). As of March 31, 2020, all the outstanding warrants ~~were converted to common shares.~~had been fully exercised.

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 directors in exchange for the cancellation of existing restricted phantom stock units, unvested restricted shares and 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 August 8, 2018, the Company filed its Second Amended and Restated Articles of Incorporation, which, among other things: (i) effected a 2.5-for-1 stock split of its common stock; and (ii) increased the authorized number of shares of its common and preferred stock to 125,000,000 and 5,000,000, respectively. All references to share and per share amounts in the Company's condensed consolidated financial statements have been retrospectively revised to reflect the stock split and increase in authorized shares.

The Company's shares of common stock were listed on The NASDAQ Global Select Market under the symbol "MESA" effective August 10, 2018. On August 14, 2018, the Company completed its IPO, in which it issued and sold 9,630,000 shares of common stock, no par value, at a public offering price of $12.00 per share (the "Firm Shares"). Additionally, in connection with the IPO, the Company granted the underwriters an option to purchase up to an additional 1,444,500 shares of common stock at the same price. On September 11, 2018, the Company closed the sale of 1,344,500 shares ("Option Shares") of its common stock, in connection with the partial exercise of the overallotment option granted to the underwriters in its IPO. Of the 1,344,500 Option Shares sold, 723,985 were purchased directly from the Company and the remaining 620,515 shares were purchased directly from the selling shareholders. The Firm Shares and Option Shares were sold to the public for a price of $12.00 per share. The aggregate gross proceeds to us from the IPO were approximately $124.2 million. The Company received $111.7 million in net proceeds after deducting $8.7 million of underwriting discounts and commissions and $3.6 million in offering costs.

On April 9, 2019, and pursuant to Section 4.4 of the 2018 Plan in connection with the 2.5-for-1 stock split effected on August 8, 2018, the board of directors approved an increase in the number of shares authorized for issuance under the 2018 Plan by 1,000,000 shares of common stock.

The Company has not historically paid dividends on shares of its common stock. Additionally, the Company's aircraft lease facility (the "RASPRO" Lease Facility) with RASPRO Trust 2005, a pass-through trust contains restrictions that limit the Company's ability to or prohibit it from paying dividends to holders of its common stock.

The Company’s effective tax rate (ETR) from continuing operations was ~~40.9%~~30.7% and ~~27.6%~~28.3% for the three months and ~~six~~nine months ended ~~March 31,~~June 30, 2020, respectively, and ~~23.6%~~22.2% and ~~23.7%~~23.6% for the three months and ~~six~~nine months ended ~~March 31,~~June 30, 2019, respectively. The Company's ETR during the three months and ~~six~~nine months ended ~~March 31,~~June 30, 2020 was different from the ~~federal statutory rate of 21%~~prior year tax rates as a result of differences in the book and tax value of the vesting and exercise of stock compensation, state taxes, and changes in valuation allowance against state net operating losses, as well as differences between the book and tax deductions associated with meals, entertainment, employer provided parking, and compensation of officers. The non-deductible amounts related to these items increased slightly from the prior year to the current year.

The Company's ETR during the ~~six~~nine months ended ~~March 31,~~June 30, 2019 was different than the statutory rate as a result of state taxes, the vesting and exercises of stock compensation, differences in the GAAP and tax deductibility of meals and parking benefits, and changes in the valuation allowance against state net operating losses.

As of September 30, 2019, the Company had aggregate federal and state net operating loss carryovers of approximately ~~$478.2~~$478.3 million and ~~$228.0~~$228.3 million, respectively, which expire in fiscal years 2027-2037 and 2020-2039, respectively. Approximately $2.7 million of state net operating loss carryforwards are expected to expire in the current fiscal year.

The restricted share activity for the ~~three~~nine months ended ~~March 31,~~June 30, 2020 were summarized as follows:

As of ~~March 31,~~June 30, 2020, there was ~~$4.4~~$5.0 million of total unrecognized compensation cost related to unvested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of ~~1.9~~2.4 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 ~~March 31,~~June 30, 2020 and 2019 was ~~$1.2~~$1.0 million and ~~$1.3~~$1.5 million, respectively, and for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019 was ~~$2.5~~$3.5 million and ~~$2.8~~$4.3 million, respectively.

The Company repurchased ~~18,244~~112,587 shares of its common stock for ~~$0.04~~$0.5 million to cover the income tax obligation on vested employee equity awards and warrant ~~conversions~~exercises during the ~~six~~nine months ended ~~March 31,~~June 30, 2020.

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

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 ~~March 31,~~June 30, 2020, eligible employees purchased and the ~~company~~Company issued 43,934 Mesa Air Group, Inc. ordinary shares under the 2019 ESPP.

EffectiveOctober 1, 2019, the Company adopted Topic 842 and recorded ROU assets and lease liabilities of $154.6 million and $141.9 million, respectively. As part of the adoption, prepaid aircraft rent, deferred rent credits and accrued aircraft rents of $35.8 million, $21.3 million and $1.8 million, respectively, were classified as a component of the Company’s ROU assets.

At ~~March 31,~~June 30, 2020, the Company leased 18 aircraft, airport facilities, office space, and other property and equipment under non-cancelable operating leases. The leases require the Company 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 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. Aggregate rental expense under all operating aircraft, equipment and facility leases totaled approximately ~~$18.6~~$15.6 million and ~~$18.7~~$18.1 million for the three months ended ~~March 31,~~June 30, 2020 and 2019, respectively, and ~~$35.4~~$51.0 million and ~~$37.8~~$55.9 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 and ~~2019.~~2019, respectively.

As of ~~March 31,~~June 30, 2020, the Company’s operating lease right-of-use assets were ~~$140.8~~$131.5 million, the Company’s current maturities of operating lease liabilities were ~~$43.6~~$43.2 million, and the Company’s noncurrent lease liabilities were ~~$78.7~~$71.1 million.

As of ~~March 31,~~June 30, 2020, the Company’s operating lease payments in operating cash flows for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 is ~~$26.2~~$34.9 million. The disclosure is not applicable for the ~~six~~nine months ended ~~March 31,~~June 30, 2019 due to the method of adoption of the new leasing Standard ASC-842.⁽¹⁾

On March 26, 2020, the Company and General Electric Company (“GE”), acting through its GE-Aviation business unit, entered into (a) Amended and Restated Letter Agreement No. 13-1 (“Letter Agreement No. 13-1”), which amends and restates Letter Agreement No. 13 entered into by the parties effective December 11, 2019, and (b) Amended and Restated Letter Agreement No. 12-1 (“Letter Agreement No. 12-1” and together with Letter Agreement No. 13-1, the “Amended and Restated Letter Agreements”), which amends and restates Letter Agreement No. 12 entered into by the parties effective October 22, 2019. The Amended and Restated Letter Agreements each provide that they are effective March 20, 2020.

Under Letter Agreement No. 13-1, the Company has agreed to purchase and take delivery of 20 new spare CF34-8C5 engines. Delivery of the new spare engines will now commence in April 2021, with the final spare engine being delivered in December 2021. The parties had previously agreed to commence delivery of the new spare engines in August 2020. The payment terms for the new spare engines were also amended, with payments to now be made in four (4) separate tranches commencing in October and December 2020 and February and March 2021.

Under Letter Agreement No. 12-1, the Company has agreed to purchase and take delivery of two (2) new spare CF34-8C5 engines by no later than March 31, 2020. The parties agreed that progress payments previously made by the Company constitute full payment for these engines. The Company does not consider this Letter Agreement to be a material definitive agreement, as defined by the rules and regulations of the Securities and Exchange Commission, but has elected to voluntarily file such Letter Agreement along with the filing of Letter Agreement No. 13-1. The total purchase commitment under these agreements is approximately ~~$118.9~~$108.0 million.

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

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

The Company adopted ASU 2016-18 on a retrospective basis during the quarter ended December 31, 2018. The following is a reconciliation of the captions in the Condensed Consolidated Balance Sheets to the Condensed Consolidated Statements of Cash Flows (in thousands):

The restricted cash balance primarily includes deposits in trust accounts to collateralize letters of credit and to fund workers' compensation claims, landing fees, and other business needs.

On March 27, 2020, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") into law. This relief package includes financial grant providing the airline industry with up to $25 billion to be used for employee wages, salaries and benefits.None.

In April 2020, the Company was granted $92.5 million in emergency relief through the payroll support program of the CARES Act to be paid in installments through September 2020. The Company received the first installment of $30.8 million in April 2020 and the remaining $61.6 million is scheduled to be paid to Mesa in four equal payments from June to September 2020.

The relief payments are conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs through September 30, 2020. Other conditions include prohibitions on share repurchases and dividends through September 30, 2021, continuing essential air service as directed by the U.S. Department of Transportation and certain limitations on executive compensation.

The CARES Act provides for up to $25 billion in secured loans to the airline industry. The Company has submitted the application for a loan under the loan program and is awaiting the outcome of the application. Under the Loan Program, the Company expects to have the ability, through September 30, 2020, to borrow a currently undetermined amount from the U.S. Treasury Department for a term of up to five years. Any loans issued under the Loan Program are expected to be senior secured obligations of the Company, with collateral to be determined. If the Company borrows any amounts under the Loan Program, the Company expects to issue to the U.S. Treasury Department warrants to purchase shares of MESA common stock.

The CARES Act also provides for deferred payment of the employer portion of social security taxes through the end of 2020. The Company expects to defer approximately $7.0 million with 50% of the deferred amount to be repaid on December 31, 2021 and the remaining 50% to be repaid on December 31, 2022.

~~These aforementioned reliefs under the CARES Act are expected to provide liquidity during the locked down and recovery periods this year.~~

One of our aircraft lenders has agreed to defer $28 million of principal debt payments otherwise due beginning on March 19, 2020, to and including September 30, 2020. All Deferred Payments shall be due in a lump sum payment on September 30, 2020 per the letter agreement dated April 9, 2020. Although the agreement is to pay the full amount back on September 30, 2020, the Company is seeking more favorable repayment terms from the lender. There is no certainty on whether the repayment terms will be able to be modified.

~~Removal of Aircraft from Code Share and Revenue Sharing Agreement with American Airlines~~

In April 2020, the Company received a withdrawal notice from American seeking to permanently withdraw three aircraft from the Code Share and Revenue Sharing Agreement. Two of the aircraft will be withdrawn effective May 19, 2020 and the third aircraft will be withdrawn effective June 1, 2020. American’s withdrawal of these three aircraft stems from withdrawal rights that American previously asserted were triggered in September 2019 and November 2019. At such time, American refrained from exercising such withdrawal rights, however, reserved the right to withdrawal the three aircraft at a later date under certain circumstances. In light of the rapid grounding of aircraft caused by the COVID-19 virus, the overall reduction in demand for air travel, and the need to reduce capacity, American has elected to remove such aircraft now.

~~Following the removal of the three aircraft referenced above, the Company will continue to operate 56 CRJ-900 aircraft under the American CPA.~~

The Company further reports that, beginning in March 2020, it has experienced a material decline in demand in block hours from both of its major airline partners, American and United Airlines, Inc. (“United” and together with American, the “Partners”) resulting from the spread of the COVID-19 virus. As a result of this decline in demand and the subsequent capacity reductions by the Company’s Partners, the Company operated 10,297 block hours in April 2020, a 72.4% drop from April 2019. The Company also anticipates similar schedule reductions will likely continue into the second quarter of 2020 and may continue throughout the remainder of 2020 and into 2021.

Item 2. ~~Management'~~sManagement'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 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 flight service to ~~135~~66 cities in 3929 states, the District of Columbia ~~Canada, Mexico, Cuba~~ and ~~the Bahamas.~~Mexico. All of our flights are operated as either American Eagle or United Express flights pursuant to the terms of capacity purchase agreements we entered into with American Airlines, Inc. ("American") and United Airlines, Inc. ("United") (each, our "major airline partner"). We have a significant presence in several of our major airline partners' key domestic hubs and focus cities, including Dallas, Houston, Phoenix and Washington-Dulles.

As of ~~March 31,~~June 30, 2020, we operated a fleet of 145 aircraft with approximately ~~662~~175 daily departures. We operate 5954 CRJ-900 aircraft under our capacity purchase agreement with American (our "American Capacity Purchase Agreement") and 20 CRJ-700 and 60 E-175 aircraft under our capacity purchase agreement with United (our "United Capacity Purchase Agreement"). For the three months ended ~~March 31,~~June 30, 2020, approximately ~~49%~~40% of our aircraft in scheduled service were operated for United and approximately ~~51%~~60% were operated for American. All of our operating revenue in our fiscal year ended September 30, 2019 (our "2019 fiscal year") and the ~~six~~nine months ended ~~March 31,~~June 30, 2020 was derived from operations associated with our American and United Capacity Purchase Agreements.

Our long-term capacity purchase agreements 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 actually flown, and reimbursement of certain direct operating expenses in exchange for providing regional flying on behalf of our major airline partners. Our capacity purchase agreements 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 capacity purchase agreements, we use the logos, service marks, flight crew uniforms and aircraft paint schemes of our major airline partners. Our major airline partners control route selection, pricing, seat inventories, marketing and scheduling, and provide us with ground support services, airport landing slots and gate access.

On January 30, 2020, the World Health Organization declared an outbreak of a highly contagious form of an upper respiratory infection caused by COVID-19, a novel coronavirus strain commonly referred to as “coronavirus”. In March 2020, the outbreak of COVID-19 was recognized as a pandemic by the World Health Organization, and the outbreak has become increasingly widespread, including in all of the markets in which we operate. The COVID-19 outbreak has had a notable impact on general economic conditions, including but not limited to the temporary closures of many businesses; “shelter in place” and other governmental regulations; reduced spending due to both job losses and other effects attributable to COVID-19; and an unprecedented decline in air travel.

The unprecedented and rapid spread of COVID-19 and the related travel restrictions and social distancing measures implemented throughout the world have significantly reduced demand for air travel. The length and severity of the reduction in demand due to the pandemic remains uncertain. This reduction in demand has had an unprecedented and materially adverse impact on our revenues and financial position. The length and severity of the reduction in demand due to the pandemic is uncertain; accordingly, we expect the adverse impact to grow in the June 2020 quarter. While we are planning for a modest demand recovery beginning in the September 2020 quarter, the exact timing and pace of ~~the~~a recovery in demand is uncertain given the significant impact of the pandemic on the overall U.S. and global economy. Our forecasted expense management and liquidity measures may be modified as we clarify the demand recovery timing. Since a portion of our revenue is fixed due to the structure of our capacity purchase agreements, the impact to Mesa will be ~~less severe due to the significant reduction in our scheduled flying.~~partially mitigated or offset. In addition, we have limited exposure to fluctuations in passenger traffic, ticket and fuel prices. While ~~our~~the fixed revenue remains mostly unchanged, ~~our~~the variable revenue ~~which~~ based on the number of block hours ~~actually flown,~~ was significantly reduced in the last few weeks ofin March and wein the June 2020 quarter. We may experience further ~~reductions.~~reductions in subsequent quarters. The ~~initiatives~~Company further reports that, beginning in March 2020, it experienced a material decline in demand in block hours from both of its major airline partners, American and ~~measures put in place to limit~~United Airlines, Inc. (“United” and together with American, the “Partners”) resulting from the spread of the ~~virus~~COVID-19 virus. As a result of this decline in demand and the subsequent capacity reductions by the Company’s Partners, the Company operated at significantly lower block hours in the June 2020 quarter. While there has been a modest demand recovery, the Company anticipates similar schedule reductions will likely continue into the fourth quarter of 2020 and ~~will~~may continue ~~to have a material adverse impact on our business, financial position~~throughout the remainder of calendar year 2020 and ~~results of operations.~~into 2021.

In response to these developments, we have implemented measures to focus on the safety of our customers and employees, while at the same time seeking to mitigate the impact on our financial position and operations. These measures include, but are not limited to, the following:

Expense Management. With the reduction in revenue, we have, and will continue to implement cost saving initiatives, including:

The following discussion summarizes the key components of our condensed consolidated statements of operations.

Our condensed consolidated operating revenues consist primarily of contract revenue flight services 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 with our major airline partners, along with the additional amounts received based on the number of flights and block hours flown. Contract revenues we receive from our major airline partners are paid and recognized by us on a weekly basis.

Pass-Through and Other. Pass-through and other revenue consists of passenger and hull insurance, aircraft property taxes, and 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, 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 airline partners. Accordingly, we do not record an expense or the related revenue for fuel supplied by American and United for flying under our capacity purchase agreements.

Maintenance. Maintenance includes costs related to salaries and benefits earned by our maintenance personnel, engine overhauls, airframe, landing gear and normal recurring maintenance, which includes pass-through maintenance costs related to our E-175 aircraft, as well as maintenance lease return obligations on our leased aircraft when the expense is probable and can be reasonably estimated. We record these expenses using the direct expense method of accounting, wherein the expense is recognized when the maintenance work is completed, or over the repair period, if materially different. Our maintenance policy is determined by fleet when major maintenance is incurred. As a result of using the direct expense method, the timing of maintenance expense reflected in the financial statements may vary significantly period to period.

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

Aircraft and Traffic Servicing. Aircraft and traffic servicing 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 airline 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.

Interest Expense. Interest expense is interest on our debt to finance purchases of aircraft, engines, equipment as well as debt financing costs amortization.

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

Other Expense. Other expense includes expense derived from activities not classified in any other area of the condensed consolidated statements of income, including write-offs of miscellaneous third-party fees.

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing operating performance. In consideration of ASC 280, "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.

While we operate under two separate capacity purchase agreements, 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 present Adjusted EBITDA and Adjusted EBITDAR in this Quarterly Report on Form 10-Q, which are not recognized financial measures under GAAP, 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, lease termination costs, loss on extinguishment of debt, and 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, lease termination costs, loss on extinguishment of debt, and 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; and (vi) 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 ~~March 31,~~June 30, 2020 Compared to Three Months Ended ~~March 31,~~June 30, 2019

We had operating income of ~~$13.9~~$15.2 million in our three months ended ~~March 31,~~June 30, 2020 compared to operating income of ~~$34.4~~$17.1 million in our three months ended ~~March 31,~~June 30, 2019.

"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.

During the three months ended June 30, 2020, the Company completed a significantly lower than normal number of flights due to the impact of COVID-19. Since the revenue recognition is based on number of flights completed, the fixed amount of cash received exceeded the revenue recognized based on the number of flights completed during the quarter. Under US GAAP, the fixed monthly payments are recognized as revenue ratably based on completed flights over the contract term. As a result, the Company deferred $16.0 million of revenue in the three months ended June 30, 2020. The deferred revenue will be recognized when flights are completed over the remaining contract term.

Aircraft Rent. Aircraft rent expense ~~decreased $1.8~~increased $2.7 million, or ~~12.9%~~21.0%, to ~~$12.3~~$15.6 million for ~~our~~ three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The ~~decrease~~increase is ~~attributable~~due to $4.9 million in additional engine rent expense offset by a ~~$3.9~~$2.1 million decrease in aircraft lease expense as a result of purchasing ten CRJ-700 aircraft in June 2019 which were previously leased under the GECAS Lease ~~Facility in June 2019, offset by a $2.1 million increase in engine rent due to additional leased engines.~~Facility.

Aircraft and Traffic Servicing.Aircraft and traffic servicing expense ~~increased $0.3~~decreased $0.4 million, or ~~25.4%~~45.0%, to ~~$1.3~~$0.5 million for ~~our~~ three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The ~~increase~~decrease is primarily due to ~~an increase~~a decrease in ~~interrupted trip expense, offset partially by~~ pass-through regulatory charges. For our three months ended ~~March 31,~~June 30, 2020 and 2019, ~~32.0%~~7.9% and ~~57.3%~~56.8%, respectively, of our aircraft and traffic servicing expenses were reimbursed by our major airline partners.

General and Administrative. General and administrative expense ~~increased $1.0~~decreased $0.7 million, or ~~7.6%~~5.6%, to ~~$14.5~~$11.7 million for ~~our~~ three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The ~~increase~~decrease is primarily due to a decrease in wages and pass-through insurance expense, partially offset by an increase in ~~wage expense.~~property taxes. For our three months ended ~~March 31,~~June 30, 2020 and 2019, ~~$4.9~~$3.9 million and ~~$4.5~~$3.7 million, respectively, of our insurance and property tax expenses were reimbursed by our major airline partners.

Depreciation and Amortization. Depreciation and amortization expense increased ~~$1.2~~$0.9 million, or ~~6.2%~~4.4%, to ~~$20.5~~$20.6 million for ~~our~~ three months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase is primarily attributable to an increase in depreciation expense related to the purchase of ten CRJ-700 aircraft which were previously leased under the GECAS Lease Facility. The increase ~~was also partially related to the purchase of spare engines and rotable inventory,~~is partially offset by a decrease in aircraft enhancement depreciation.

Lease Termination. Lease termination expense decreased $9.5 million, or 100.0%, to $0.0 million for three months ended June 30, 2020 compared to the same period in 2019. We incurred a lease termination expense for the ten CRJ-700 aircraft purchased in June 2019 that were previously leased under the GECAS facility.

CARES Act Grant Recognition. CARES Act grant recognition increased $43.0 million, or 100.0%, to $43.0 million for three months ended June 30, 2020 compared to none in the same period in 2019. Under the CARES Act, the government provided the company $46.3 million in payroll support during the quarter ended June 30, 2020. The company has recorded $43.0 million to offset the payroll expenses in the quarter ended June 30, 2020 and $3.3 million has been deferred to offset the future payroll costs. The support offsets payroll expenses recorded in the functional areas of the operating expense lines.

Other expense decreased ~~$6.3~~$2.9 million, or ~~37.2%~~22.1%, to ~~$10.7~~$10.3 million for ~~our~~ three months ended ~~March 31,~~June 30, 2020, compared to the same period in 2019. The decrease is primarily a result of a decrease in ~~interest expense due to lower interest rates on our new Spare Engine Facility and a decrease in~~ outstanding aircraft principal balances. ~~Additionally, we had one-time $3.6 million early termination fee related to our engine financing in the three months ended March 31, 2019.~~

The Company's effective tax rate (ETR) from continuing operations was ~~40.9%~~30.7% for the three months ended ~~March 31,~~June 30, 2020 and ~~23.6%~~22.2% for the three months ended ~~March 31,~~June 30, 2019. The Company's current year effective tax rate increased compared to the prior year tax rate as a result of an increase to permanent differences between book and taxable income in the deductibility of meals, employer provided parking, and compensation of officers. 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. In addition, changes to the Company forecast for fiscal 2020 related to the implications of the coronavirus pandemic had the effect of increasing the effective tax rate for the quarter, as the Company’s forecasted pre-tax book income decreased substantially from the prior year.

The income tax provision for the three months ended ~~March 31,~~June 30, 2020 results in an effective tax rate of ~~40.9%~~30.7%, which differs from the U.S. federal statutory rate of 21% primarily due to permanent book and tax deductible expense differences, state taxes, changes in the valuation allowance against state net operating losses, routine stock vestings and exercises, and changes in state apportionment and state statutory ~~rates, and the impact of a lower forecasted income projection for the year due to concerns around the coronavirus pandemic and the impact on air travel.~~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.

As of September 30, 2019, the Company had aggregate federal and state net operating loss carryforwards of ~~$478.2~~$478.3 million and ~~$228.0~~$228.3 million, respectively, which expire in 2027-2037 and 2020-2039, respectively. Approximately $2.7 million of state net operating loss carryforwards are expiring in 2020.

Nine Months Ended ~~March 31,~~June 30, 2020 Compared to ~~Six~~Nine Months Ended ~~March 31,~~June 30, 2019

We had operating income of ~~$41.1~~$56.3 million in our ~~six~~nine months ended ~~March 31,~~June 30, 2020 compared to operating income of ~~$73.6~~$90.7 million in our ~~six~~nine months ended ~~March 31,~~June 30, 2019. In our ~~six~~nine months ended ~~March 31,~~June 30, 2020, we had net income of ~~$12.7~~$16.0 million compared to net income of ~~$32.3~~$35.3 million in our ~~six~~nine months ended ~~March 31,~~June 30, 2019. Our operating results for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 reflected a decrease in contract revenue primarily related to ~~removal of five aircraft from our American Capacity Purchase Agreement and an increase~~the decrease in ~~pass-through and other revenues primarily~~flying due to ~~an increase in maintenance pass-through expense.~~COVID-19.

Our flight operations expense decreased this quarter due to lower pilot and flight attendant wages and pilot training expenses as a result of less flying due to COVID-19. Our maintenance expense increased primarily due to more airframe C-Checks and engine heavy maintenance events due to timing of events. Our aircraft rent decreased in the six months ended March 31, 2020 compared to the same period in 2019 primarily as a result of purchasing ten CRJ-700 aircraft that were previously leased under our GECAS Lease Facility. We also had an increase in depreciation expense primarily due to the purchase of ten CRJ-700 aircraft that were previously leased under our GECAS Lease Facility. We had a decrease in lease termination expense relating to the purchase of ten CRJ-700 aircraft in June 2019 that were previously leased under our GECAS Lease Facility. In addition, we recognized the Federal Grant received through the Payroll Support Agreement under the CARES Act with the U.S. Department of the Treasury.

Flight Operations. Flight operations expense ~~increased $2.9~~decreased $20.4 million, or ~~2.8%~~13.1%, to ~~$105.5~~$135.2 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The ~~increase~~decrease was primarily driven by ~~an increase~~a decrease in pilot and flight attendant ~~wages.~~wages, pilot training related costs, and employee related expense as a result of less flying due to COVID-19. The decrease was also due to $5.0 million in tax credits provided by the Employee Retention Credit under the CARES Act related to the quarter ended June 30, 2020

Fuel.Fuel expense increased $0.1 million, or ~~61.3%~~16.4%, to ~~$0.4~~$0.5 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase was primarily driven by an increase in ferry flight fuel. All fuel costs related to flying under our capacity purchase agreements during our ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019 were directly paid to suppliers by our major airline partners.

Maintenance.Aircraft maintenance costs increased ~~$37.2~~$5.5 million, or ~~43.7%~~4.0%, to ~~$122.4~~$145.0 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. This increase was primarily driven by an increase in engine overhaul expense, airframe C-Check expense, offset by a decrease in component contracts, rotable and ~~labor~~expendable, and other pass-through expense. Total pass-through maintenance expenses reimbursed by our major airline partners increased by ~~$10.3~~$2.6 million during our ~~six~~nine months ended ~~March 31,~~June 30, 2020.

The following table presents information regarding our maintenance costs during our ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019 (in thousands):

Aircraft Rent. Aircraft rent expense decreased ~~$4.6~~$1.9 million, or ~~16.3%~~4.6%, to ~~$23.6~~$39.2 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The decrease is attributable to a ~~$7.8~~$9.9 million decrease in aircraft lease expense as a result of purchasing ten CRJ-700 aircraft in June 2019 which were previously leased under the GECAS Lease Facility, ~~in June 2019,~~ offset by ~~a $3.2~~an $8.0 million increase in engine rent due to additional ~~leased engines.~~engine rent expense.

Aircraft and Traffic Servicing. Aircraft and traffic servicing expense ~~increased $0.4~~decreased $0.04 million, or ~~20.1%~~1.3%, to ~~$2.4~~$2.9 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The ~~increase~~decrease is primarily due to a decrease in pass-through regulatory charges, offset by an increase in interrupted trip ~~expense, offset partially by pass-through regulatory charges.~~expense. For our ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019, ~~36.5%~~31.3% and ~~57.2%~~57.1%, respectively, of our aircraft and traffic servicing expenses were reimbursed by our major airline partners.

General and Administrative. General and administrative expense increased ~~$1.8~~$1.1 million, or ~~7.0%~~2.9%, to ~~$27.5~~$39.2 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase is primarily due to an increase in pass-through ~~insurance expenses and wage~~property tax, partially offset by a decrease in legal expense. For our ~~six~~nine months ended ~~March 31,~~June 30, 2020 and 2019, ~~$9.3~~$13.2 million and ~~$7.6~~$11.3 million, respectively, of our insurance and property tax expenses were reimbursed by our major airline partners.

Depreciation and Amortization. Depreciation and amortization expense increased ~~$3.3~~$4.1 million, or ~~8.6%~~7.2%, to ~~$41.0~~$61.7 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020 compared to the same period in 2019. The increase is primarily attributable to an increase in depreciation expense related to the purchase of ten CRJ-700 aircraft which were previously leased under the GECAS Lease Facility. The increase was also partially related to the purchase of ~~spare engines and~~ rotable inventory, partially offset by a decrease in aircraft improvement depreciation.

Lease Termination. Lease termination expense decreased $9.5 million, or 100.0%, to $0.0 million for nine months ended June 30, 2020 compared to the same period in 2019. We incurred a lease termination expense for the ten CRJ-700 aircraft purchased in June 2019 that were previously leased under the GECAS facility.

Other expense decreased ~~$7.7~~$10.6 million, or ~~24.6%~~23.9%, to ~~$23.6~~$33.9 million for ~~our six~~nine months ended ~~March 31,~~June 30, 2020, compared to the same period in 2019. The decrease is primarily a result of a decrease in interest expense due to lower interest rates on our new Spare Engine Facility and a decrease in outstanding aircraft principal balances. Additionally, we had one-time $3.6 million early termination fee related to our engine financing in the ~~six~~nine months ended ~~March 31,~~June 30, 2019. We also saw a decrease in interest income.

The income tax expense (benefit) totaled ~~$4.8~~$6.4 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 as compared to a tax expense (benefit) of ~~$10.0~~$10.9 million for the ~~six~~nine months ended ~~March 31,~~June 30, 2019. The effective tax rate was ~~27.6%~~28.3% versus ~~23.7%~~23.6% in the prior year.

The effective tax rate for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 was impacted by permanent difference between book and taxable income in the deductibility of meals, employer provided parking, and compensation of officers. The effective rate was also impacted by changes in the valuation allowance against state net operating losses, vesting and exercises of stock compensation, and changes in state apportionment and 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 ~~2016~~2017 and 2015 for federal and state purposes, respectively, with the exception of the examination of our net operating losses. The balance of unrecognized tax benefits is not anticipated to fluctuate significantly from fiscal 2019 to fiscal 2020. It is our policy to recognize interest expense and penalties related to uncertain income tax matters as a component of income tax expense.

As a result of the COVID-19 pandemic, we have taken, and are continuing to take, certain actions to increase liquidity and strengthen our financial position which include:

Reducing planned heavy engine and airframe maintenance events by approximately ~~$3.7~~$16.8 million in the current fiscal year.

Working with major partners and original equipment manufacturers ("OEM") to delay the timing of our future aircraft and spare engine deliveries.

Drew $23.0 million from our previously undrawn revolving credit facility with CIT Bank, N.A.

One of our aircraft lenders has agreed to defer ~~$28~~$28.0 million of principal debt payments ~~with one of our aircraft lenders~~ otherwise due beginning on March 19, 2020, to and including September 30, 2020. All ~~Deferred Payments shall~~deferred payments will be due in a lump sum payment on September 30, 2020 per ~~the~~a letter agreement dated April 9, 2020. Although the agreement is to pay the full amount back on September 30, 2020, the Company is seeking more favorable repayment terms from the lender. ~~There is no certainty on whether the repayment terms~~No assurance can be given that we will be ~~able~~successful in further modifying or securing more favorable repayment terms. The company performed a debt modification accounting assessment and determined that this event is a debt modification and no changes to ~~be modified.~~the current accounting treatment is required.

In June 2020, the Company amended its RASPRO aircraft agreement to defer a $4.0 million lease payment otherwise due in June 2020. Per the amended agreement dated June 5,2020, the Company is required to pay this amount over the period of September 2021 through March 2024. The Company made the accounting election available for COVID-19 related concession provided by a lessor. This event is not a lease modification and requires changes to current accounting treatment.

In April 2020, we were granted $92.5 million in emergency relief through the payroll support program of the CARES Act to be paid in installments through September 2020. We received ~~the first installment~~$46.3 million as of ~~$30.8 million in April~~June 2020, and the remaining ~~$61.6~~$46.2 million is scheduled to be paid to Mesa in ~~four~~three equal monthly payments from ~~June~~July to September ~~2020.~~2020.$43.0 million has been utilized to offset the payroll expenses in the quarter ended June 30, 2020 and $3.3 million has been deferred to offset future payroll costs.

The relief payments are conditioned on our agreement to refrain from conducting involuntary employee layoffs or furloughs through September 30, 2020. Other conditions include continuing essential air service as directed by the U.S. Department of Transportation and certain limitations on executive compensation.

The CARES Act also provides for up to $25 billion in secured loans to the airline industry. We have ~~submitted an application for a loan~~been allocated $277.0 million under the loan ~~program of $184 million for working capital, $568 million for financing new equipment and $252 million for financing existing equipment and~~program. We are ~~awaiting~~in ongoing discussions with the ~~outcome~~U.S. Department of the ~~application process.~~ Treasury regarding the terms and our participation level of such a loan.

The CARES Act provides for deferred payment of the employer portion of social security taxes through the end of 2020. The Company expects to defer approximately $7.0 million of such taxes, with 50% of the deferred amount to be repaid on December 31, 2021 and the remaining 50% to be repaid on December 31, 2022.

These aforementioned reliefs from the CARES Act are expected to provide liquidity during the stay at home and recovery periods this year.

We expect to meet our cash needs for the next twelve months with cash and cash equivalents, financing arrangements, government assistance from the CARES Act, and cash flows from operations. As of ~~March 31,~~June 30, 2020, we had ~~$52~~$65 million in unrestricted liquidity. Additionally, we have five unencumbered CRJ-700 aircraft available to use as collateral for potential financing arrangements if needed. However, we continue to monitor the impact of the pandemic, including its adverse effect on customer demand, the general economy, and our major airline partners. Should the effects of the pandemic continue long-term, our capital requirements and sources of capital may be adversely impaired. See Part II, Item 1A, Risk Factors for additional discussion.

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 cash on hand, cash generated from operations and funds from external borrowings. In the near term, we expect to fund our primary cash requirements through cash generated from operations and cash and cash equivalents on hand. We also have the ability to utilize our credit and guaranty agreement (the "CIT Revolving Credit Facility") pursuant to which the CIT Lenders committed to lend to Mesa Airlines and Mesa Air Group—Airline Inventory Management, LLC, ("MAG-AIM") revolving loans in the aggregate principal amount of up to $35.0 million. As of ~~March 31,~~June 30, 2020, $12.0 million remains available for borrowing until the facility matures on August 12, 2022.

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 our 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 to 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 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 from 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. Our capital expenditures, net of purchases of rotable spare parts and aircraft and spare engine financing for the three months ~~ending March 31,2020~~ended June 30, 2020 is approximately ~~2.9%~~6.4% which is higher compared to our historical expense of approximately 1.2% to 1.5% of annual revenues not only due to expenses incurred related to aircraft ~~enhancements.~~enhancements but also a decrease in revenue due to the COVID-19 pandemic impact on the airline industry. We expect to continue 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 ~~March 31,~~June 30, 2020, our principal sources of liquidity were cash and cash equivalents of ~~$52.4~~$64.9 million. In addition, we had restricted cash of $3.4 million as of ~~March 31,~~June 30, 2020. Restricted cash includes certificates of deposit that secure letters of credit issued for particular airport authorities as required in certain lease agreements. Primary uses of liquidity are capital expenditures, and debt repayments. As of ~~March 31,~~June 30, 2020, we had ~~$168.2~~$176.9 million of short-term debt, excluding financing leases, and ~~$619.8~~$586.9 million of long-term debt excluding financing leases.

Sources of cash for the ~~six~~nine months ended ~~March 31,~~June 30, 2020 were primarily cash flows from operations of ~~$65.2~~$103.6 million. This positive cash flow was primarily driven by receipts from performance under our capacity purchase agreements.

As of ~~March 31,~~June 30, 2020, we had $3.4 million in restricted cash. We have an agreement with a financial institution for a $6.0 million letter of credit facility and to issue letters of credit for landing fees, worker's compensation insurance and other business needs. Pursuant to ~~the~~such agreement, $3.5 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 three months ended ~~March 31,~~June 30, 2020 and 2019 (in thousands):

During our ~~six~~nine months ended ~~March 31,~~June 30, 2019, cash flow provided by operating activities of ~~$69.8~~$114.1 million reflects our growth and execution of our strategic initiatives. We had net income of ~~$32.3~~$35.3 million adjusted for the following significant non-cash items: depreciation and amortization of ~~$37.8~~$57.5 million, stock-based compensation of ~~$2.8~~$4.3 million, deferred income taxes of ~~$10.0~~ $10.9million, amortization of unfavorable lease liabilities and deferred credits of ~~$(5.7)~~$(8.4) million, amortization of debt financing costs and accretion of interest on non-interest bearing subordinated notes of ~~$2.0~~$3.1 million, and loss on extinguishment of debt of $3.6 million and loss on lease termination of $9.5 million. We had a net change of ~~$(13.1)~~$(2.3) million within other net operating assets and liabilities largely driven by ~~an increase~~a decrease in prepaid expenses and other current assets primarily due to the purchase of ten CRJ-700 aircraft ~~lease payments~~that were previously leased under our GECAS Lease Facility during our ~~six~~nine months ended ~~March 31,~~June 30, 2019.

During our ~~six~~nine months ended ~~March 31,~~June 30, 2020, net cash flow used in investing activities totaled ~~$(24.8)~~$(25.1) million. We invested ~~$(3.6)~~$(11.0) million in spare engines and (3.8) million in aircraft improvements, ~~$(7.6)~~$(8.4) million in inventory, ~~$(1.7)~~$(1.9) million in tools and miscellaneous projects and $(13.8) million in lease and equipment deposits offset by ~~$2.0~~$13.9 million from the return of lease and equipment deposits.

During our ~~six~~nine months ended ~~March 31,~~June 30, 2019, net cash flow used in investing activities totaled ~~$(18.5)~~$(96.0) million. We invested ~~$(34.3)~~$116.7 million in ~~six~~ten aircraft and seven spare engines and aircraft improvements, ~~and $(7.3) million in lease and equipment deposits~~ offset by ~~$3.0 million from return of lease and equipment deposits million in net equipment deposits, and $20.0~~$20.1 million from sales of investment ~~securities.~~securities, and $0.6 million in equipment deposits

During our ~~six~~nine months ended ~~March 31,~~June 30, 2020, net cash flow used in financing activities was ~~$(57.1)~~$(82.6) million. We drew $23.0 million from our $35.0 million working capital draw loan for operational needs. We made ~~$(79.4)~~$(104.0) million of principal repayments on long-term debt during the period. We incurred ~~$(0.5)~~$(1.4) million of costs related to debt financing and ~~$(0.2)~~$(0.5) million of costs related to the repurchase of shares of our common stock.

During our ~~six~~nine months ended ~~March 31,~~June 30, 2019, net cash flow used in financing activities was ~~$(77.0)~~$(41.6) million. We received ~~$91.2~~$163.7 million in proceeds from long-term debt primarily related to purchasing ten aircraft, and spare aircraft engine and aircraft engine kit financing. We made ~~$(163.7)~~$197.4 million of principal repayments on long-term debt during the period. We incurred ~~$(2.5)~~$4.9 million of costs related to debt financing, ~~and $(1.7)~~$1.7 million in debt prepayment ~~costs.~~costs, and $1.5 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.

There have been no material changes outside of the ordinary course of business in our commitments and contractual obligations from those specified in our Form 10-K for the fiscal year ended September 30, 2019.

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.

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, which have been prepared in accordance with accounting principles generally accepted in the United States. We believe certain of our accounting policies are critical to understanding our financial position and results of operations. Except with respect to our revenue recognition practices included in Note 2: "Summary of Significant Accounting Policies" in the notes to our unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, there have been no changes to the critical accounting policies as explained in Part 1, Item 7 of the ~~2018~~2019 Form 10-K under the heading "Critical Accounting Policies."

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 3:4: "Summary of Significant Accounting Policies" 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 ~~March 31,~~June 30, 2020, we had ~~$533.1~~$510.4 million of variable-rate debt including current maturities. A hypothetical 50 basis point change in market interest rates would have affected interest expense by approximately ~~$2.7~~$2.6 million in the twelve months ended ~~March 31,~~June 30, 2020.

As of ~~March 31,~~June 30, 2020, we had ~~$272.4~~$270.8 million of fixed-rate debt, including current maturities. A hypothetical 50 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 ~~March 31,~~June 30, 2020.

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 of calculating LIBOR 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 have on financial markets for LIBOR-linked financial instruments. 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 ~~March 31,~~June 20, 2020, we had ~~$533.1~~$510.4 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 airline 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")), 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.

There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended June 30, 2020, to which this report relates that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting of the Company.

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.

The Company is subject to two putative class action lawsuits alleging federal securities law violations in connection with its 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 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. The plaintiffs seek unspecified monetary damages and other relief. We do not currently believe that this matter is likely to have a material adverse impact on our consolidated results of operations, cash flows, or our financial position. However, any litigation is inherently uncertain, and any judgment or injunctive relief entered against us or any adverse settlement could materially and adversely impact our business, results of operations, financial condition, and prospects.

In addition, from time to time the Company may become involved in legal proceedings or be subject to claims arising in the ordinary course of its business. Although the results of such litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business, operating results, financial condition or cash flows. Regardless of the outcome, any such litigation and claims can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors.

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, 2019 (the “2019 10-K”), as updated by the information disclosed in “Part II, Item 1A. Risk Factors” in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 (the “Second Quarter Form 10-Q”), each of 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~~the 2019 Form 10-K ~~for~~and the ~~fiscal year ended September 30, 2019 and herein~~Second Quarter Form 10-Q 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.~~results particularly in light of the fast-changing nature of the COVID-19 pandemic, containment measures, the potential for future waves of outbreaks and the related impacts to the travel industry and on our major airlines partners.

We have updated our existing risk factors to add the following risk factor related to recent developments. Except for the ~~update~~updates set forth below, there have been no material changes in our risk factors from those disclosed in our ~~Annual Report on Form~~2019 10-K, ~~for the fiscal year ended September 30, 2019.~~as updated in our Second Quarter 10-Q.

The outbreak and global spread of COVID-19 has resulted in a severe decline in demand for air travel which has adversely impacted the business of our airline partners, American Airlines, Inc. (“American”) and United Airlines, Inc. (“United”), and in turn had had an adverse impact that has been material to our business, operating results, financial condition and liquidity. The duration and severity of the COVID-19 pandemic, and similar public health threats that we may face in the future, could result in additional adverse effects on our business, operating results, financial condition and liquidity.

The COVID-19 outbreak, along with the measures governments and private organizations worldwide have implemented in an attempt to contain the spread of this pandemic, has resulted in a severe decline in demand for air travel, which has adversely affected the business of our major airline partners, American and United (the “Partners”), from whom we derive all of our operating revenue, and in turn has adversely affected our business, operations and financial condition to an unprecedented extent. Measures ranging from travel restrictions, “shelter in place” and quarantine orders, limitations on public gatherings to cancellation of public events and many others have resulted in a precipitous decline in demand for both business and leisure travel worldwide.

In response to this material deterioration in demand, both American and United made significant cuts in capacity in their domestic and international schedules in April and announced their expectations regarding making further reductions in May and plans to proactively evaluate and cancel flights on a rolling 90-day basis until they see signs of a recovery in demand. These capacity reductions have impacted flights operated by the Company. The initiatives and measures put in place to limit the spread of the virus has and will continue to have a materially adverse impact on our business. The Company further reports that, beginning in March 2020, it has experienced a material decline in demand in block hours from both of its major airline partners, American and United Airlines, Inc. (“United” and together with American, the “Partners”) resulting from the spread of the COVID-19 virus. As a result of this decline in demand and the subsequent capacity reductions by the Company’s Partners, the Company operated ~~10,297~~at significantly lower block hours in ~~April 2020,~~the third quarter of 2020. While there has been a ~~72.4% drop~~

~~from April 2019. The~~modest demand recovery, the Company ~~also~~ anticipates similar schedule reductions will likely continue into the ~~second~~fourth quarter of 2020 and may continue throughout the remainder of 2020 and ~~into 2021.~~the foreseeable future.

As a result of the foregoing, the Company has implemented cost saving initiatives, including reducing employee-related costs through voluntary unpaid leaves, compensation reductions for Executive level employees, a company-wide hiring freeze, and delaying non-essential heavy maintenance expense and reducing or suspending discretionary spending, We have also taken steps to increase liquidity and strengthen our financial position, including reducing planned heavy engine and airframe maintenance, working with major partners and OEMs to delay the timing of the delivery of our future aircraft and spare engine deliveries, and ~~drew~~drawing $23 million under our previously undrawn revolving credit facility. While the severity, magnitude and duration of the COVID-19 pandemic remain uncertain, there can be no assurance that these actions will be sufficient to sustain our business operations through this pandemic.

We have taken and intend to take additional actions to improve our financial position, including measures to improve liquidity, such as obtaining financial assistance under the CARES Act. In April 2020, we were granted $92.5 million in emergency relief through the Payroll Support Program of the CARES Act. We received ~~the first installment~~$46.3 million as of ~~$30.8 million in late April~~June 2020 and expect to receive the remaining ~~$61.6~~$46.2 million in ~~four~~three equal installments from ~~June~~July to September 2020. The Company is also considering borrowing up to approximately $277 million from the U.S. Treasury Department pursuant to the loan program under the CARES Act. In connection with the financial assistance we have received and expect to receive under this legislation, we will be required to comply with certain provisions of the CARES Act, including the requirement that funds provided pursuant to the Payroll Support Program be used exclusively for the continuation of payment of employee wages, salaries and benefits; the requirement against involuntary furloughs and reductions in employee pay rates and benefits through September 2020; the requirement of continuing essential air service; restrictions on share repurchases and dividends; and limits on the payment of certain executive compensation. The substance and duration of these restrictions may materially affect our operations, and we may not be successful in managing these ~~impacts.~~impacts for the duration of the restrictions. In particular, limitations on executive compensation, which, depending on the form of aid, could extend up to six years, may impact the Company's ability to attract and retain senior management or attract other key employees during this critical time.

The full extent of the ongoing impact of COVID-19 on our future operational and financial performance will depend on future developments, many of which are outside our control, including the effectiveness of the mitigation strategies discussed above, the severity, magnitude, duration and spread of COVID-19, including any recurrence of the pandemic, and related travel advisories and restrictions, the impact of COVID-19 on overall long-term demand for air travel, the impact on demand and capacity which could result from government mandates on air service including, for instance, any requirement for passengers to wear masks while traveling or have their temperature checked or have administered other tests or examinations prior to entering an airport or boarding an airplane, or which would limit the number of seats that can be occupied on an aircraft to allow for social distancing, the impact of COVID-19 on the financial health and operations of our Partners and future governmental actions, all of which are highly uncertain and cannot be predicted.

In addition, an outbreak of another disease or similar public health threat, or fear of such an event, that affects travel demand, travel behavior or travel restrictions could adversely impact our business, financial condition and operating results. Outbreaks of other diseases could also result in increased government restrictions and regulation, such as those actions described above or otherwise, which could adversely affect our operations.

The Company has a significant amount of debt and other contractual obligations and intends to seek material amounts of additional financial liquidity in the short-term, and insufficient liquidity may have a material adverse effect on the Company's financial condition and business.

The Company has a significant amount of debt and other contractual obligations, including debt incurred in connection with the acquisition of aircraft and aircraft engines, and long-term lease obligations primarily relating to our aircraft fleet. In addition, the Company has substantial noncancelable commitments for capital expenditures, including for the acquisition of new aircraft and related spare engines.

In addition, in response to the travel restrictions, decreased demand for air travel and other effects the COVID-19 pandemic has had and is expected to have on our major airline partners and, in turn, on the Company's business, the Company currently intends to continue to seek material amounts of additional financial liquidity in the short-term, which may include the proposed drawing of loans under the loan program of the CARES Act.

There can be no assurance as to the timing of any such incurrence, which may be in the near term, or that any such additional financing will be completed on favorable terms, or at all. As of June 30, 2020, we had total long-term debt of $777.7 million (including current portion of $176.8 million) and $12.0 million available for borrowing under our CIT Revolving Credit Facility at June 30, 2020. We received $46.3 million under the payroll support program under the CARES Act as of June 30, 2020, and expect to receive the remaining $46.2 million in three equal payments from July to September 2020. As discussed elsewhere in this Quarterly Report on Form 10-Q, we are eligible for a $277.0 million loan under the loan program of the CARES Act.

The Company's substantial level of indebtedness, the Company's non-investment grade credit ratings and the availability of Company assets as collateral for loans or other indebtedness, which available collateral would be reduced as a result of any CARES Act loan program borrowings and other future liquidity-raising transactions, may make it difficult for the Company to raise additional capital if needed to meet its liquidity needs on acceptable terms, or at all.

Although the Company's cash flows from operations and its available capital, including the proceeds from financing transactions, have been sufficient to meet its obligations and commitments to date, the Company's liquidity has been, and may in the future be, negatively affected by the risk factors discussed in the 2019 Form 10-K, as updated by the Second Quarter 10-Q and this report, including risks related to future results arising from the COVID-19 pandemic. If the Company's liquidity is materially diminished, the Company's cash flow available to fund its working capital requirements, capital expenditures and business development efforts may be materially and adversely affected.

A material reduction in the Company's liquidity could also result in the Company not being able to timely pay its leases and debts or comply with material provisions of its contractual obligations, including covenants under its financing agreements and leases with, among others, CIT, Export Development Canada, and RASPRO Trust 2005. In addition, several of the Company's debt agreements contain affirmative and negative covenants that, among other things, restrict the ability of the Company and its subsidiaries to enter into, create, incur, assume or suffer to exist any liens.

In addition to the foregoing, the degree to which we are leveraged could have important consequences to holders of our securities, including the following:

See Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations, of this report for additional information regarding the Company's liquidity as of June 30, 2020.

The loss of key personnel upon whom we depend to operate our business or the inability to attract additional qualified personnel could adversely affect our business.

We believe that our future success will depend in large part on our ability to retain or attract highly qualified management, technical and other personnel. We may not be successful in retaining key personnel or in attracting other highly qualified personnel. Among other things, the CARES Act imposes significant restrictions on executive compensation which, assuming we receive a secured loan from Treasury, will remain in place through the date that is one year after such secured loan is fully repaid. Such restrictions, over time, will likely result in lower executive compensation in the airline industry than is prevailing in other industries which may present retention challenges in the case of executives presented with alternative, non-airline opportunities. Any inability to retain or attract significant numbers of qualified management and other personnel would have a material adverse effect on our business, results of operations and financial condition.

The Inability to Secure Financing for the Twenty New E-175 Aircraft Scheduled for Delivery Beginning in September 2020 May Negatively Affect Our Prospects, Operations and Financial Condition.

As we previously reported, our United Capacity Purchase Agreement provides for the addition of twenty (20) new Embraer E175 aircraft to the scope of such Agreement. We intend to finance and own these new aircraft and operate them for a period of twelve (12) years from the in-service date. While deliveries of the new E-175 aircraft are scheduled to begin in September 2020 and continue through June 2021, as of the date of this Quarterly Report on Form 10-Q, given the current COVID-19 environment, we do not currently have the financing in place to acquire and take delivery of such aircraft. If we are unable to secure such financing on a timely basis or at all, we could forfeit the right to acquire some or all of such aircraft. A loss of the aircraft to a competitor could have a material adverse effect on our business prospects, financial condition, results of operations, and cash flows.

~~None.~~The Company repurchased 112,587 shares of its common stock for $0.5 million to cover the income tax obligation on vested employee equity awards and warrant exercises during the nine months ended June 30, 2020.
