Mesa Air Group, Inc. ("Mesa" or the "Company") is a holding company whose principal subsidiary operates as a regional air carrier, providing scheduled passenger service. As of September 30, 2020, the Company served 102 cities in 39 states, the District of Columbia and Mexico, and operated a fleet of 146 aircraft with approximately 373 daily departures.

The Company's airline operations are conducted by its regional airline subsidiary, Mesa Airlines, Inc. ("Mesa Airlines"), providing services to major air carriers under capacity purchase agreements. Mesa Airlines operates as American Eagle under a capacity purchase agreement with American Airlines, Inc. ("American") and as United Express under a capacity purchase agreement with United Airlines, Inc. ("United"). All of the Company's consolidated contract revenues for years ended September 30, 2020, 2019 and 2018 were derived from operations associated with these two capacity purchase agreements.

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 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 certain 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.

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 consolidated financial statements have been retrospectively revised to reflect the stock split and increase in authorized shares.

On August 14, 2018, the Company completed an initial public offering ("IPO") of its common stock, in which it issued and sold 9,630,000 shares (the "Firm Shares") of common stock at a public offering price of $12.00 per share, resulting in gross proceeds to the Company of approximately $115.6 million. 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 sale of these shares raised gross proceeds of approximately $124,247,820. The Company did not receive any proceeds from the sale of the Option Shares by the selling shareholders.

As part of the IPO, stock appreciation rights ("SARs") previously issued under the Mesa Air Group, Inc. Amended and Restated Stock Appreciation Rights Plan (the "SAR Plan"), which settled only in cash, were cancelled and exchanged for an aggregate of 1,266,034 shares of restricted common stock under the Company's 2018 Equity Incentive Plan (the "2018 Plan") (see note 13 "Share-Based Compensation"), of which 966,022 were fully vested upon issuance and are included in the number of shares of common stock outstanding after the IPO. Of the 966,022 fully vested shares, 314,198 shares were retained by the Company to satisfy tax withholding obligations, resulting in a net issuance of 651,824 shares. Additionally, 983,113 shares of restricted common stock were issued to certain of its employees and directors under its

2018 Plan in exchange for the cancellation of 491,915 shares of existing unvested restricted phantom stock units and 491,198 shares of restricted stock under the 2011 and 2017 Plans, respectively.

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 exact timing and pace of 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 the 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 contract consideration remains mostly unchanged, the variable revenue based on number of block hours was significantly reduced beginning in the last few weeks in March and in the June 2020 and September 2020 quarters. We may experience further reductions in subsequent quarters. The 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 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 at significantly lower block hours in the second half of fiscal year 2020. While there has been a modest demand recovery, the Company anticipates similar schedule reductions may continue throughout the remainder of calendar year 2020 the foreseeable future.

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 September 30, 2020, our cash and cash equivalents balance was $99.4 million. We have taken the following actions to increase liquidity and strengthen our financial position.

In April 2020, we were granted $92.5 million in emergency relief through the Payroll Support Program of the CARES Act, which was received as of September 30, 2020. In September we were notified that, based on funding availability, recipients that were currently in compliance with signed payroll support program agreements would receive an approximate 2% increase in their award amount. As a result, we were granted an additional $2.7 million for a total grant of $95.2 million, which was received in October 2020. $83.8 million has been utilized to offset the payroll expenses in the year ended September 30, 2020 and $11.4 million has been deferred to offset future payroll costs which we expect to utilize in Q1 2021. In connection with the Payroll Support Program, we are required to comply with the relevant provisions of the CARES Act, including the requirement that funds provided pursuant to the agreement 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, which expired on September 30, 2020, the requirement that certain levels of commercial air service be maintained as well as those that restrict the payment of certain

The CARES Act also provides for up to $25 billion in secured loans to the airline industry. In October 2020, the Company entered into a five-year Loan and Guarantee with the U.S. Treasury Department which provides the Company with a secured loan facility to borrow up to $200.0 million under the CARES Act. On October 30, 2020, the Company borrowed $43.0 million under the facility and on November 13, 2020, the Company borrowed an additional $152.0 million totaling $195.0 million. No further borrowings are available under the Loan Agreement. All borrowings under the Loan Agreement will bear interest at an annual rate based on Adjusted LIBO (as defined in the Loan Agreement) plus 3.5%. Accrued interest on the loans is payable in arrears on the first business day following the 14th day of each March, June, September and December (beginning with December 15, 2020), and on the maturity date. Interest will be paid during the first twelve months by increasing the principal amount of the loan by the amount of such interest due on an interest payment date, unless Mesa Airlines elects to pay interest in cash at least 30 days prior to each applicable interest payment date. The borrower obligations are guaranteed by the Company and Mesa Air Group Inventory Management. The proceeds may be used for general corporate purposes and operating expenses, to the extent permitted by the CARES Act. All advances under the Loan Agreement will be in the form of term loans, all of which will mature and be due and payable in a single installment on the Maturity Date. Voluntary prepayments of loans under the Loan Agreement may be made, in whole or in part, by Mesa Airlines, without premium or penalty, at any time and from time to time. Amounts prepaid may not be reborrowed. Mandatory prepayments of loans under the Loan Agreement are required, without premium or penalty, to the extent necessary to comply with covenants, certain dispositions of the Collateral, certain debt issuances secured by liens on the Collateral and certain insurance payments related to the Collateral. In addition, if a “change of control” (as defined in the Loan Agreement) occurs with respect to Mesa Airlines, Mesa Airlines will be required to repay the loans outstanding under the Loan Agreement.

As of September 30, 2020, the Company operated 54 CRJ-900 aircraft for American under a 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 31 aircraft that are due to expire in 2021, the 16 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) 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 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 of the two previously deferred aircraft, effective January 2, 2020. As of January 2, 2020, American had removed three (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 aircraft from the American Capacity Purchase Agreement. Two of the aircraft were withdrawn effective May 19, 2020 and the third aircraft 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 in early June.

On June 11, 2020, the 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 two (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 aircraft for the same period and (ii) the addition of utilization-based credits, entitling American to 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 CARES Act. The impact of the contract modification was not material to the three or year ended September 30, 2020

American had a 0.0%, 7.1% and 7.2% ownership interest in the Company, calculated on a fully-diluted basis as of September 30, 2020, 2019 and 2018, respectively. The related party amounts presented on the consolidated balance sheets and statements of operations and comprehensive income pertain to American.

As of September 30, 2020, we 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. 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.

On November 26, 2019, we amended and restated our United Capacity Purchase Agreement to, among other things, incorporate the terms of the 14 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 were to 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 were scheduled to begin in May 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. In addition, we own 18 E-175 aircraft that expire in 2028. As part of the amended and restated United Capacity Purchase Agreement, we agreed to lease our 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 to the new service provider. United has a right to purchase the CRJ-700 aircraft at the then fair market value.

On November 4, 2020, we amended and restated our United Capacity Purchase Agreement to, among other things, amend the ownership by United, in lieu of Mesa Airlines, of 20 E175LL aircraft that will be leased to Mesa Airlines. Per the amendment, these new aircraft will be now financed by United Airlines and leased to the Company to operate for a period of twelve (12) years from the in-service date. We agreed to adjusted rates to account for the change in ownership of the E175LL aircraft, relief from certain provisions related to minimum utilization until December 31, 2021 and an additional right of United to remove one or more E175LL aircraft in the event that the Mesa Airlines fails to meet certain financial covenants. We also agreed to a one-time provision for United to prepay $85.0 million under the United CPA for future performance by Mesa Airlines (the “Prepayment”) and the application of certain discounts to certain payment obligations of United under the United CPA. Weekly payments under the United CPA will be discounted following the Prepayment until repaid. Until the Prepayment is fully expended, weekly amounts due from United under the United CPA will be applied toward the balance of the Prepayment. This period is estimated to continue for approximately 4 months following funding of the Prepayment. The terms of the Prepayment also include affirmative and negative covenants and events of default customary for

transactions of this type. Proceeds from the Prepayment will retire debt on certain airframes and engines that will serve as collateral under the term loan facility provided to Mesa Airlines by the U.S. Treasury.

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