Unless otherwise stated, references to particular years, quarters, months or periods refer to our fiscal years ended September 30 and the associated quarters, months, and periods of those fiscal years. Each of the terms the "Company," "Mesa Airlines," "we," "us" and "our" as used herein refers collectively to Mesa Air Group, Inc. and its wholly owned subsidiaries, unless otherwise stated. We do not assume any obligation to revise or update any forward- looking statements. 3 PART I ITEM 1. BUSINESS General Mesa Airlines is a regional air carrier providing scheduled passenger service to 125 cities in 39 states, the District of Columbia, Canada, Mexico and Cuba. 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 September 30, 2019, we operated a fleet of 145 aircraft with approximately 730 daily departures. We operate 62 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 our fiscal year ended September 30, 2019, approximately 44% of our aircraft in scheduled service were operated for American and approximately 56% were operated for United. All of our operating revenue in our 2019, 2018 and 2017 fiscal years was derived from operations associated with our American and United Capacity Purchase Agreements. Our capacity purchase agreements provide us guaranteed monthly revenue for each aircraft under contract, a fixed fee for each block hour 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, to an extent, 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. Regional aircraft are optimal for short and medium-haul scheduled flights that connect outlying communities with larger cities and act as "feeders" for domestic and international hubs. In addition, regional aircraft are well suited to serve larger city pairs during off-peak times when load factors on larger jets are low. The lower trip costs and operating efficiencies of regional aircraft, along with the competitive nature of the capacity purchase agreement bidding process, provide significant value to major airlines. According to the Regional Airline Association, we were the 3rd largest regional airline in the United States in 2018, as measured by passenger enplanements, and our flights accounted for approximately 9.0% of all passengers carried on U.S. regional airlines. Regional airlines play a daily, essential role in the U.S. air travel system. According to the Regional Airline Association, 41% of all scheduled passenger flights in the United States in 2018 were operated by regional airlines. Of all the U.S. airports with scheduled passenger service, 63% are served exclusively by regional airlines. Some of the most popular U.S. airports have more than half of their scheduled departures made by regional aircraft, including New York-LaGuardia, Philadelphia, Washington-Dulles, Charlotte, Houston-Bush and Chicago-O'Hare. Our Business Strategy Our business strategy consists of the following elements: Maintain Low-Cost Structure. We have established ourselves as a low cost, efficient and reliable provider of regional airline services. We intend to continue our disciplined cost control approach through responsible outsourcing of certain operating functions, by flying large regional aircraft with associated lower maintenance costs and common flight crews across fleet types, and through the diligent control of corporate and administrative costs implementing company-wide efforts to improve our cost position. Additionally, we expect our long-term collective bargaining agreements to protect us from significant labor cost increases over the next five years. These efficiencies, coupled with the low average seniority of our pilots, has enabled us to compete aggressively on price in our capacity purchase agreement negotiations. Attractive Work Opportunities. We believe our employees have been, and will continue to be, a key to our success. Our ability to attract, recruit and retain pilots has supported our industry-leading fleet growth. We intend to continue to offer competitive compensation packages, foster a positive and supportive work environment and provide opportunities to fly state-of-the-art, large-gauged regional jets to differentiate us from other carriers and make us an attractive place to work and build a career. 4 Maintain a Prudent and Conservative Capital Structure. We intend to continue to maintain a prudent capital structure. We believe that the strength of our balance sheet and credit profile will enable us to optimize terms with lessors and vendors and, when preferred by our major airline partners, allow us to procure and finance aircraft on competitive terms. Minimize Tail Risk. We have structured our aircraft leases and financing arrangements to minimize or eliminate, as much as possible, so-called "tail risk," which is the amount of aircraft-related lease obligations or projected negative equity existing beyond the term of that aircraft's corresponding capacity purchase agreement. As of September 30, 2019, we had 17 aircraft with leases extending past the term of their corresponding capacity purchase agreements with an aggregate exposure of approximately $32.2 million and no financing arrangements with projected negative equity. We intend to continue to align the terms of our aircraft leases and financing agreements with the terms of our capacity purchase agreements in order to maintain low "tail risk." Aircraft Fleet We fly only large regional jets manufactured by Bombardier and Embraer S.A. ("Embraer"). Operating large regional aircraft allows us to enjoy operational, recruiting and cost advantages over other regional airlines that operate smaller regional aircraft. As of September 30, 2019, we had 145 aircraft (owned and leased) consisting of the following: Embraer Regional Jet-175 (76 seats)(1) Canadair Regional Jet-700 (70 seats) Canadair Regional Jet-900 (76-79 seats) Canadair Regional Jet-200 (50 seats)(2) American Eagle United Express Subtotal Unassigned Total — 60 60 — 60 — 20 20 — 20 62 — 62 2 64 — — — 1 1 Total 62 80 142 3 145 (1) (2) In April 2019, we converted two aircraft to operational spares and removed them from service under our American Capacity Purchase Agreement. CRJ-200 is an operational spare not assigned for service under our capacity purchase agreements. The following table lists the aircraft we own and lease as of September 30, 2019: Type of Aircraft E-175 Regional Jet CRJ-900 Regional Jet CRJ-700 Regional Jet CRJ-200 Regional Jet Total Owned Leased Total 18 48 18 1 85 42 (1) 16 2 0 60 60 64 20 1 145 Passenger Capacity 76 76/79 70 50 (1) These aircraft are owned by United and leased to us at nominal amounts. The Bombardier and Embraer regional jets are among the quietest commercial jets currently available and offer many of the amenities of larger commercial jet aircraft, including flight attendant service, a stand-up cabin, overhead and under seat storage, lavatories and in-flight snack and beverage service. The speed of Bombardier and Embraer regional jets is comparable to larger aircraft operated by major airlines, and they have a range of approximately 1,600 miles and 2,100 miles, respectively. We do not currently have any existing arrangements with Bombardier or Embraer to acquire additional aircraft. Capacity Purchase Agreements Our capacity purchase agreements consist of the following: (cid:3) Operation of CRJ-900 aircraft under our American Capacity Purchase Agreement; and (cid:3) Operation of CRJ-700 and E-175 aircraft under our United Capacity Purchase Agreement. 5 The financial arrangement underlying our American and United Capacity Purchase Agreements includes a revenue- guarantee arrangement. Under the revenue-guarantee provisions of our capacity purchase agreements, our major airline partners pay us a fixed minimum monthly amount per aircraft under contract, plus additional amounts related to departures and block hours flown. We also receive direct reimbursement of certain operating expenses, including insurance. Other expenses, including fuel and ground operations are directly paid to suppliers by our major airline partners. We believe we are in material compliance with the terms of our capacity purchase agreements and enjoy good relationships with our major airline partners. We benefit from our capacity purchase agreements and revenue guarantees because we are sheltered, to an extent, from some of the elements that cause volatility in airline financial performance, including variations in ticket prices, fluctuations in number of passengers and fuel prices. However, we do not benefit from positive trends in ticket prices (including ancillary revenue programs), the number of passengers enplaned or reductions in fuel prices. Our major airline partners retain all revenue collected from passengers carried on our flights. In providing regional flying under our capacity purchase agreements, we use the logos, service marks and aircraft paint schemes of our major airline partners. The following table summarizes our available seat miles ("ASMs") flown and contract revenue recognized under our capacity purchase agreements for our fiscal years ended September 30, 2019 and 2018, respectively: American United Total Year Ended September 30, 2019 Year Ended September 30, 2018 Available Seat Miles Contract Revenue (in thousands) Contract Revenue per ASM Available Seat Miles Contract Revenue (in thousands) Contract Revenue per ASM 4,735,534 $376,506 ¢ 6,128,089 $306,328 ¢ 10,863,623 $682,834 ¢ 7.95 4,417,228 $359,467 ¢ 5.00 5,296,649 $279,797 ¢ 6.29 9,713,877 $639,264 ¢ 8.14 5.28 6.58 American Capacity Purchase Agreement As of September 30, 2019, we operated 62 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 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. For our fiscal years ended September 30, 2019 and 2018, we issued credits of approximately $0.0 million and $5.2 million, respectively, under 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. American has the option to unilaterally extend the term of our American Capacity Purchase Agreement up to three times for one year each (on the same terms) by providing us prior written notice. Our American Capacity Purchase Agreement is subject to termination prior to that date, subject to our right to cure, in various circumstances including: (cid:3) (cid:3) (cid:3) If either American or we become insolvent, file for bankruptcy or fail to pay our debts as they become due, the non- defaulting party may terminate the agreement; Failure by us or American to perform the covenants, conditions or provisions of our American Capacity Purchase Agreement, subject to 15 days' notice and cure rights; If we are required by the FAA or the DOT to suspend operations and we have not resumed operations within three business days, except as a result of an emergency airworthiness directive from the FAA affecting all similarly equipped aircraft, American may terminate the agreement; 6 (cid:3) If our controllable flight completion factor falls below certain levels for a specified period of time, subject to our right to cure; or (cid:3) Upon a change in our ownership or control without the written approval of American. 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. As of September 30, 2019, American held 7.1% of our outstanding common stock on a fully-diluted basis, which interest American received in exchange for an extension of our capacity purchase agreement during our bankruptcy proceeding. 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. United Capacity Purchase Agreement As of September 30, 2019, 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. 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. In February 2018, we mutually agreed with United to temporarily remove two aircraft from service under our United Capacity Purchase Agreement. In July 2018, we were able to fully staff flight operations and these aircraft were placed back into service. During the temporary removal, we agreed to pay the lease costs associated with the two E-175 aircraft, which totaled $1.9 million as of September 30, 2018. 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 11 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 scheduled to begin in May 2020 and be completed by December 31, 2020. 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. 7 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 over the period between May 2020 and December 2020. United has a right to purchase the 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: (cid:3) (cid:3) (cid:3) (cid:3) By United if certain operational performance factors fall below a specified percentage for a specified time, subject to notice under certain circumstances; By United if we fail to perform the material covenants, agreements, terms or conditions of our United Capacity Purchase Agreement or similar agreements with United, subject to thirty (30) days' notice and cure rights; If either United or we become insolvent, file bankruptcy or fail to pay debts when due, the non-defaulting party may terminate the agreement; or By United if we merge with, or if control of us is acquired by another air carrier or a corporation directly or indirectly owning or controlling another air carrier. Maintenance and Repairs Airlines are subject to extensive regulation. We have a FAA mandated and approved maintenance program. Aircraft maintenance and repair consists of routine and non-routine maintenance, and work performed is divided into three general categories: line maintenance, heavy maintenance and component service. We also outsource certain aircraft maintenance and other operating functions. We use competitive bidding among qualified vendors to procure these services. We have long-term maintenance contracts with AAR to provide fixed-rate parts procurement and component overhaul services for our aircraft fleet. Under these agreements, AAR provides maintenance and engineering services on any aircraft that we designate during the term of the agreement, along with access to a spare parts inventory pool in exchange for a fixed monthly fee. Our agreements with AAR expire in 2026, unless earlier terminated for cause. We have not experienced difficulty obtaining spare parts on a timely basis for our aircraft fleet. As of September 30, 2019, $52.8 million of parts inventory was consigned to us by AAR under long-term contracts that is not reflected on our balance sheet. Line maintenance consists of routine daily and weekly scheduled maintenance checks on our aircraft. Line maintenance is performed at certain locations throughout our system and represents the majority of and most extensive maintenance we perform. Major airframe maintenance checks consist of a series of more complex tasks that can take from one to four weeks to accomplish and typically are required approximately every 28 months, on average across our fleet. Engine overhauls and engine performance restoration events are quite extensive and can take two months. We maintain an inventory of spare engines to provide for continued operations during engine maintenance events. We expect to begin the initial planned engine maintenance overhauls on our new engine fleet approximately four to six years after the date of manufacture and introduction into our fleet, with subsequent engine maintenance every four to six years thereafter. Due to our current fleet size, we believe outsourcing all of our heavy maintenance, engine restoration and major part repair, is more economical than performing this work using our internal maintenance team. Competition We consider our competition to be those U.S. regional airlines that currently hold or compete for capacity purchase agreements with major airlines. Our competition includes, therefore, nearly every other domestic regional airline, including Air Wisconsin Airlines Corporation; Endeavor Air, Inc. (owned by Delta) ("Endeavor"); Envoy Air, Inc. ("Envoy"), PSA Airlines, Inc. ("PSA") and Piedmont Airlines, Inc. ("Piedmont") (Envoy, PSA and Piedmont are owned by American); Horizon Air Industries, Inc. (owned by Alaska Air Group, Inc.) ("Horizon"); SkyWest Inc., parent of SkyWest Airlines, Inc. and ExpressJet Airlines, Inc.; Republic Airways Holdings Inc.; and Trans States Airlines, Inc. Major airlines typically offer capacity purchase arrangements to regional airlines on the basis of the following criteria: availability of labor resources; proposed contract economic terms; reliable and on-time flight operations; corporate financial resources including ability to procure and finance aircraft; customer service levels; and other factors. 8 Certain of our competitors are larger and have significantly greater financial and other resources than we do. Moreover, economic downturns, combined with competitive pressures, have contributed to a number of reorganizations, bankruptcies, liquidations and business combinations among major and regional carriers. The effect of economic downturns is somewhat mitigated by our reliance on capacity purchase agreements with revenue-guarantee provisions, but the renewal and continued profitability of these partnerships with our major airline partners is not guaranteed. Seasonality Our results of operations for any interim period are not necessarily indicative of those for the entire year, since the airline industry is subject to seasonal fluctuations and general economic conditions. Our operations are somewhat favorably affected by increased utilization of our aircraft in the summer months and are unfavorably affected by increased fleet maintenance and by inclement weather during the winter months. Aircraft Fuel Our capacity purchase agreements provide that our major airline partners source, procure and directly pay third-party vendors for all fuel used in the performance of those agreements. Accordingly, we do not recognize fuel expenses or revenues for flying under our capacity purchase agreements and we face very limited exposure to fuel price fluctuations. Insurance We maintain insurance policies we believe are of types customary in the airline industry and as required by the DOT, lessors and other financing parties and our major airline partners under the terms of our capacity purchase agreements. The policies principally provide liability coverage for public and passenger injury; damage to property; loss of or damage to flight equipment; fire; auto; directors' and officers' liability; advertiser and media liability; cyber risk liability; fiduciary; workers' compensation and employer's liability; and war risk (terrorism). Although we currently believe our insurance coverage is adequate, we cannot assure you that the amount of such coverage will not be changed or that we will not be forced to bear substantial losses from accidents. Employees As of September 30, 2019, we employed approximately 3,576 employees, consisting of 1,375 pilots or pilot recruits, 1,330 flight attendants, 60 flight dispatchers, 517 mechanics and 294 employees in administrative roles. Our continued success is partly dependent on our ability to continue to attract and retain qualified personnel. We have never been the subject of a labor strike or labor action that materially impacted our operations. FAA regulations require pilots to have an Airline Transport Pilot ("ATP") license with specific ratings for the aircraft to be flown, and to be medically certified as physically fit to fly. FAA and medical certifications are subject to periodic renewal requirements including recurrent training and recent flying experience. Mechanics, quality-control inspectors, and flight dispatchers must be certificated and qualified for specific aircraft. Flight attendants must have initial and periodic competency training and qualification. Training programs are subject to approval and monitoring by the FAA. Management personnel directly involved in the supervision of flight operations, training, maintenance, and aircraft inspection must also meet experience standards prescribed by FAA regulations. All safety-sensitive employees are subject to pre-employment, random, and post-accident drug testing. The airline industry has from time to time experienced a shortage of qualified personnel, particularly with respect to pilots and maintenance technicians. In addition, as is common with most of our competitors, we have faced considerable turnover of our employees. Regional airline pilots, flight attendants and maintenance technicians often leave to work for larger airlines, which generally offer higher salaries and better benefit programs than regional airlines are financially able to offer. Should the turnover of employees, particularly pilots, sharply increase, the result will be significantly higher training costs than otherwise would be necessary and we may need to request a reduced flight schedule with our major airline partners, which may result in operational performance penalties under our capacity purchase agreements. We cannot assure you that we will be able to recruit, train and retain the qualified employees that we need to carry out our expansion plans or replace departing employees. 9 As of September 30, 2019, approximately 75.6% of our employees were represented by labor unions under collective- bargaining agreements, as set forth below. No other employees of ours or our subsidiaries are parties to any other collective bargaining agreement or union contracts. Employee Groups Pilots Flight Attendants Dispatchers Mechanics Administrative Number of Employees Representative 1,375 Air Line Pilots Association 1,330 Association of Flight Attendants Labor Agreement Expiration 7/13/2021 10/1/2021 60 N/A 517 N/A 294 N/A The Railway Labor Act ("RLA") governs our relations with labor organizations. Under the RLA, the collective bargaining agreements generally do not expire, but instead become amendable as of a stated date. If either party wishes to modify the terms of any such agreement, they must notify the other party in the manner agreed to by the parties. Under the RLA, after receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request the National Mediation Board ("NMB") to appoint a federal mediator. The RLA prescribes no set timetable for the direct negotiation and mediation process. It is not unusual for those processes to last for many months, and even for a few years. If no agreement is reached in mediation, the NMB in its discretion may declare at some time that an impasse exists, and if an impasse is declared, the NMB proffers binding arbitration to the parties. Either party may decline to submit to arbitration. If arbitration is rejected by either party, a 30-day "cooling off" period commences. During that period (or after), a Presidential Emergency Board ("PEB") may be established, which examines the parties' positions and recommends a solution. The PEB process lasts for 30 days and is followed by another "cooling off" period of 30 days. At the end of a "cooling off" period, unless an agreement is reached or action is taken by Congress, the labor organization may strike and the airline may resort to "self-help," including the imposition of any or all of its proposed amendments and the hiring of new employees to replace any striking workers. Congress and the President have the authority to prevent "self-help" by enacting legislation that, among other things, imposes a settlement on the parties. The table above sets forth our employee groups and status of the collective bargaining agreements. Safety and Security We are committed to the safety and security of our passengers and employees. We have taken many steps, both voluntarily and as mandated by governmental authorities, to increase the safety of our operations. Some of the safety and security measures we have taken with our major airline partners include: aircraft security and surveillance, positive bag matching procedures, enhanced passenger and baggage screening and search procedures, and securing of cockpit doors. We are committed to complying with future safety and security requirements. Our ongoing focus on safety relies on training our employees to proper standards and providing them with the tools and equipment they require so they can perform their job functions in a safe and efficient manner. Safety in the workplace targets several areas of our operation including: dispatch, flight operations and maintenance. The TSA and the U.S. Customs and Border Protection, each a division of the U.S. Department of Homeland Security, are responsible for certain civil aviation security matters, including passenger and baggage screening at U.S. airports, and international passenger prescreening prior to entry into or departure from U.S. international flights are subject to customs, border, immigration and similar requirements of equivalent foreign governmental agencies. We are currently in compliance with all directives issued by such agencies. We maintain active, open lines of communication with the TSA at all of our locations to ensure proper standards for security of our personnel, equipment and facilities are exercised throughout the operation. 10 Facilities In addition to aircraft, we have office and maintenance facilities to support our operations. Each of our facilities are summarized in the following table: Type Corporate Headquarters Training Center Parts/Stores Hangar Office, Hangar and Warehouse Office, Hangar Hangar Hangar Hangar Location Phoenix, Arizona Phoenix, Arizona Phoenix, Arizona Phoenix, Arizona El Paso, Texas Dallas, Texas Houston, Texas Louisville, Kentucky Dulles, Washington Ownership Leased Leased Leased Leased Leased Leased Leased Leased Leased Approximate Square Feet 33,770 23,783 12,000 22,467 31,292 30,440 74,524 26,762 28,451 Our corporate headquarters and training facilities in Phoenix, Arizona are subject to long-term leases expiring on November 30, 2025 and May 31, 2025, respectively. We believe our facilities are suitable and adequate for our current and anticipated needs. Foreign Ownership Under DOT regulations and federal law, we must be owned and controlled by U.S. citizens. The restrictions imposed by federal law and regulations currently require that at least 75% of our voting stock must be owned and controlled, directly and indirectly, by persons or entities who are U.S. citizens, as defined in the Federal Aviation Act, that our president and at least two-thirds of the members of our Board of Directors and other managing officers be U.S. citizens, and that we be under the actual control of U.S. citizens. In addition, at least 51% of our total outstanding stock must be owned and controlled by U.S. citizens and no more than 49% of our stock may be held, directly or indirectly, by persons or entities who are not U.S. citizens and are from countries that have entered into "open skies" air transport agreements with the U.S. which allow unrestricted access between the United States and the applicable foreign country and to points beyond the foreign country on flights serving the foreign country. We are currently in compliance with these ownership provisions. As of September 30, 2019, there were outstanding warrants to purchase 3,600,953 shares of our common stock, with an exercise price of $0.004 per share. The warrants are not exercisable in violation of the restrictions imposed by federal law requiring that no more than 24.9% of our stock be voted, directly or indirectly, or controlled by persons who are not U.S. citizens. Government Regulation Aviation Regulation The DOT and FAA have regulatory authority over air transportation in the United States and all international air service is subject to certain U.S. federal requirements and approvals, as well as the regulatory requirements of the appropriate authorities of the foreign countries involved. The DOT has authority to issue certificates of public convenience and necessity, exemptions and other economic authority required for airlines to provide domestic and foreign air transportation. International routes and international code-sharing arrangements are regulated by the DOT and by the governments of the foreign countries involved. A U.S. airline's ability to operate flights to and from international destinations is subject to the air transport agreements between the United States and the foreign country and the carrier's ability to obtain the necessary authority from the DOT and the applicable foreign government. The U.S. government has negotiated "open skies" agreements with many countries, which allow broad access between the United States and the applicable foreign country. With certain other countries, however, the United States has a restricted air transportation agreement. Our international flights to Mexico are governed by a recently implemented liberalized bilateral air transport agreements which the DOT has determined has all of the attributes of an "open skies" agreement. Our flights to Canada, Cuba and the Bahamas are governed by bilateral air transport agreements between the United States and such countries. Changes in U.S., Mexican, Canadian, Cuban or Bahamian aviation policies could result in the alteration or termination of the corresponding air transport agreement, or otherwise affect our operations to and from these countries. In particular, there is still a degree of uncertainty about the future of scheduled commercial flight operations between the United States and Cuba as a result of changes in diplomatic relations between the two governments, as well as travel and trade restrictions implemented by the U.S. government in 2017. We are largely sheltered from the economic impact changes to existing "open skies" agreements or volatility in U.S., Mexican, Canadian, Cuban or Bahamian aviation polices because our major airline partners control route selection and scheduling under our capacity purchase agreements. 11 The FAA is responsible for regulating and overseeing matters relating to the safety of air carrier flight operations, including the control of navigable air space, the qualification of flight personnel, flight training practices, compliance with FAA airline operating certificate requirements, aircraft certification and maintenance requirements and other matters affecting air safety. The FAA requires each commercial airline to obtain and hold an FAA air carrier certificate. We currently hold an FAR-121 air carrier certificate. Airport Access Flights at three major domestic airports are regulated through allocations of landing and takeoff authority (i.e., "slots" and "operating authorizations") or similar regulatory mechanisms, which limit take-offs and landings at those airports. Each slot represents the authorization to land at or take off from the particular airport during a specified time period. In the United States, the FAA currently regulates the allocation of slots, slot exemptions, operating authorizations or similar capacity allocation mechanisms at two of the airports we serve, Ronald Reagan Washington National Airport (DCA) in Washington, D.C. and New York's LaGuardia Airport (LGA). In addition, John Wayne Airport (SNA) in Orange County, California, has a locally imposed slot system. Our operations at these airports generally require the allocation of slots or analogous regulatory authorizations, which are obtained by our major airline partners. Consumer Protection Regulation The DOT also has jurisdiction over certain economic issues affecting air transportation and consumer protection matters, including unfair or deceptive practices and unfair methods of competition, lengthy tarmac delays, air carriers, airline advertising, denied boarding compensation, ticket refunds, baggage liability, contracts of carriage, customer service commitments, customer complaints and transportation of passengers with disabilities. The DOT frequently adopts new consumer protection regulations, such as rules to protect passengers addressing lengthy tarmac delays, chronically delayed flights, capacity purchase disclosure and undisclosed display bias, and is reviewing new guidelines to address the transparency of airline non-ticket fees and refunding baggage fees for delayed checked baggage. The DOT also has authority to review certain joint venture agreements, code-sharing agreements (where an airline places its designator code on a flight operated by another airline) and wet-leasing agreements (where one airline provides aircraft and crew to another airline) between carriers and regulates other economic matters such as slot transactions. Environmental Regulation We are subject to various federal, state, local and foreign laws and regulations relating to environmental protection matters. These laws and regulations govern such matters as environmental reporting, storage and disposal of materials and chemicals and aircraft noise. We are, and expect in the future to be, involved in various environmental matters and conditions at, or related to, our properties. We are not currently subject to any environmental cleanup orders or actions imposed by regulatory authorities. We are not aware of any active material environmental investigations related to our assets or properties. Other Regulations Airlines are also subject to various other federal, state, local and foreign laws and regulations. For example, the U.S. Department of Justice has jurisdiction over certain airline competition matters. Labor relations in the airline industry are generally governed by the RLA. The privacy and security of passenger and employee data is regulated by various domestic and foreign laws and regulations. The U.S. government and foreign governments may consider and adopt new laws, regulations, interpretations and policies regarding a wide variety of matters that could directly or indirectly affect our results of operations. We cannot predict what laws, regulations, interpretations and policies might be considered in the future, nor can we judge what impact, if any, the implementation of any of these proposals or changes might have on our business. Legal Proceedings We are subject to commercial and employment litigation claims and to administrative and regulatory proceedings and reviews. We currently believe that the ultimate outcome of such claims, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on our financial position, liquidity or results of operations. Additionally, from time to time we are subject to legal proceedings and regulatory oversight in the ordinary course of our business. 12 Corporate Information We are a Nevada corporation with our principal executive office in Phoenix, Arizona.

Certain factors may have a material adverse effect on our business, financial condition, and results of operation. You should carefully consider the risks and uncertainties described below, together with all of the other information included in this Annual Report on Form 10-K, including our financial statements and the related notes, and in our other filings with the SEC. Our business, financial condition, operating results, cash flow and prospects could be materially and adversely affected by any of these risks or uncertainties. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment. Risks Related to Our Business The supply of pilots to the airline industry is limited and may negatively affect our operations and financial condition. In July 2013, as directed by the U.S. Congress, the FAA issued more stringent pilot qualification and crew member flight training standards, which increased the required training time for new airline pilots (the "FAA Qualification Standards"). The FAA Qualification Standards, which became effective in August 2013, require first officers to hold an ATP certificate, requiring 1,500 hours total flight time as a pilot. Previously, first officers were required to have only a commercial pilot certificate, which required 250 hours of flight time. The rule also mandates stricter rules to minimize pilot fatigue. The FAA Qualification Standards (and associated regulations) have dramatically reduced the supply of qualified pilot candidates and has had a negative effect on pilot scheduling, work hours and the number of pilots required to be employed for our operations. To address the diminished supply of qualified pilot candidates, regional airlines, including us, implemented significant pilot wage and bonus increases. The impact of the FAA Qualification Standards (and associated regulations) has substantially increased our labor costs and may continue to negatively impact our operations and financial condition. 13 In prior periods, the FAA Qualification Standards have negatively impacted our ability to hire pilots at a rate sufficient to support required utilization levels under our American Capacity Purchase Agreement, and, as a result, we have issued credits to American pursuant to the terms of our American Capacity Purchase Agreement. We issued credits under our American Capacity Agreement of approximately $0.0 million and $5.2 million for the fiscal years ended September 30, 2019 and 2018, respectively. Also, in February 2018, we mutually agreed with United to temporarily remove two aircraft from service under our United Capacity Purchase Agreement. In July 2018, we were able to fully staff flight operations and these aircraft were placed back into service under our United Capacity Purchase Agreement. If we are unable to maintain a sufficient number of qualified pilots to operate our scheduled flights, we may need to request reduced flight schedules with our major airline partners and incur monetary performance penalties under our capacity purchase agreements. In addition, our operations and financial condition may be negatively impacted if we are unable to train pilots in a timely manner. Due to the industry-wide shortage of qualified pilots, driven by the increased flight hours requirements under the FAA Qualification Standards and attrition resulting from the hiring needs of other airlines, pilot training timelines have significantly increased and stressed the availability of flight simulators, instructors and related training equipment. As a result, the training of our pilots may not be accomplished in a cost-efficient manner or in a manner timely enough to support our operational needs. Pilot attrition may continue to negatively affect our operations and financial condition. In recent years, we have experienced significant volatility in our attrition as a result of pilot wage and bonus increases at other regional air carriers, the growth of cargo, low-cost and ultra low-cost carriers and the number of pilots at major airlines reaching the statutory mandatory retirement age of 65 years. In prior periods, these factors caused our pilot attrition rates to be higher than our ability to hire and retain replacement pilots and we have been unable to provide flight services at or exceeding the minimum flight operating levels expected by our major airline partners. If our attrition rates are higher than our ability to hire and retain replacement pilots, we may need to request a reduced flight schedule with our major airline partners, which may result in operational performance penalties under our capacity purchase agreements and our operations and financial results could be materially and adversely affected. We are highly dependent on our agreements with our major airline partners. We derive all of our operating revenue from our capacity purchase agreements with our major airlines partners. American accounted for approximately 53% and 54% of our total revenue for our fiscal years ended September 30, 2019 and 2018, respectively. United accounted for approximately 47% and 46% of our revenue for our fiscal years ended September 30, 2019 and 2018, respectively. A termination of either our American or our United capacity purchase agreement would have a material adverse effect on our business prospects, financial condition, results of operations, and cash flows. Our American Capacity Purchase Agreement expires with respect to different tranches of aircraft between 2021 and 2025, unless otherwise extended or amended. In addition, our American Capacity Purchase Agreement is subject to termination prior to expiration, subject to our right to cure, in various circumstances including if our controllable flight completion factor falls below certain levels for a specified period of time. On November 26, 2019, we amended and restated our United Capacity Purchase Agreement to extend the term of 42 of our E-175 aircraft leased from United for an additional five (5) years which will now expire between 2024 and 2028. As part of the amended agreement United has elected to have us lease our twenty (20) CRJ-700 aircraft to another United Express service provider for a term of 7 years. We will continue to operate the aircraft until they are transitioned between May 2020 and Dec 2020. In addition, we own 18 E175 aircraft that expire in 2028. United is also permitted, subject to certain conditions, to terminate the agreement early in its discretion by giving us notice of 90 days or more. Our United Capacity Purchase Agreement is also subject to termination prior to expiration, subject to our right to cure, in various circumstances including if our controllable flight completion factor or departure performance falls below certain levels for a specified period of time. If our capacity purchase agreements with American or United were terminated or not renewed, we would be significantly impacted and likely would not have an immediate source of revenue or earnings to offset such loss. Neither American nor United are under any obligation to renew their respective capacity purchase agreements with us. A termination or expiration of either of these agreements would likely have a material adverse effect on our financial condition, cash flows, ability to satisfy debt and lease obligations, operating revenues and net income unless we are able to enter into satisfactory substitute arrangements for the utilization of the affected aircraft by other airline partners, or, alternatively, obtain the airport facilities, gates, ticketing and ground services and make the other arrangements necessary to fly as an independent airline. We may not be able to enter into substitute capacity purchase arrangements, and any such arrangements we might secure may not be as favorable to us as our current agreements. Operating an airline independently from our major airline partners would be a significant departure from our business plan and would likely require significant time and resources, which may not be available to us at that point. 14 Increases in our labor costs, which constitute a substantial portion of our total operating costs, may adversely affect our business, results of operations and financial condition. As a result of the FAA Qualification Standards, the supply of qualified pilots has been dramatically reduced. This shortage of pilots has driven up our pilot salaries and sign-on bonuses and resulted in a material increase in our labor costs. A continued shortage of pilots could require us to further increase our labor costs, which would result in a material reduction in our earnings. Reduced utilization levels of our aircraft under our capacity purchase agreements would adversely impact our financial results. Historically, our major airline partners have utilized our flight operations at levels at or near the maximum capacity of our fleet allocations under our capacity purchase agreements, but there can be no assurance that they will continue utilizing our aircraft at that level. If our major airline partners schedule the utilization of our aircraft below historical levels (including taking into account the stage length and frequency of our scheduled flights), we may not be able to maintain operating efficiencies previously obtained, which would negatively impact our operating results and financial condition. Our American Capacity Purchase Agreement establishes minimum levels of flight operations. In prior periods, the FAA Qualification Standards 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 United Capacity Purchase Agreement does not require United to schedule any specified minimum level of flight operations for our aircraft. Additionally, United may remove aircraft from our United Capacity Purchase Agreement with 90 days' prior notice to us. While United pays us a fixed monthly revenue amount for each aircraft under contract, a significant reduction in the utilization levels of our fleet in the future or removal of aircraft from our United Capacity Purchase Agreement at United's election could reduce our revenues based on the number of flights and block hours flown for United. In February 2018, we mutually agreed with United to temporarily remove two aircraft from service under our United Capacity Purchase Agreement. In July 2018, we were able to fully staff flight operations and these aircraft were placed back into service under our United Capacity Purchase Agreement. Continued challenges with hiring, training and retaining replacement pilots may lead to reduced utilization levels of our aircraft and additional penalties under our capacity purchase agreements and our operations and financial results could be materially and adversely impacted. Additionally, our major airline partners may change routes and frequencies of flights, which can negatively impact our operating efficiencies. Changes in schedules may increase our flight costs, which could exceed the reimbursed rates paid by our major airline partners. Reduced utilization levels of our aircraft or other changes to our schedules under our capacity purchase agreements would adversely impact our financial results. If our major airline partners experience events that negatively impact their financial strength or operations, our operations also may be negatively impacted. We may be directly affected by the financial and operating strength of our major airline partners. Any events that negatively impact the financial strength of our major airline partners or have a long-term effect on the use of our major airline partners by airline travelers would likely have a material adverse effect on our business, financial condition and results of operations. In the event of a decrease in the financial or operational strength of any of our major airline partners, such partner may seek to reduce, or be unable to make, the payments due to us under their capacity purchase agreement. In addition, in some cases, they may reduce utilization of our aircraft. Although we receive guaranteed monthly revenue for each aircraft under contract and a fixed fee for each block hour or flight actually flown, our partners are not required to schedule any specified level of flight operations for our aircraft. If any of our other current or future major airline partners become bankrupt, our capacity purchase agreement with such partner may not be assumed in bankruptcy and could be terminated. This and other events, which are outside of our control, could have a material adverse effect on our business, financial condition and results of operations. In addition, any negative events that occur to other regional carriers and that affect public perception of such carriers generally could also have a material adverse effect on our business, financial condition and results of operations. 15 Our major airline partners may expand their direct operation of regional jets thus limiting the expansion of our relationships with them. We depend on our major airline partners electing to contract with us instead of operating their own regional jets or operating their own "captive" regional airlines through wholly owned subsidiaries. Currently, the captive regional airlines include Endeavor (owned by Delta), Envoy (owned by American), PSA (owned by American), Piedmont (owned by American) and Horizon (owned by Alaska). These major airlines possess the financial and other resources to acquire and operate their own regional jets, create or grow their own captive regional airlines or acquire other regional air carriers instead of entering into contracts with us. In particular, American, which procures approximately 40% of its regional flying from its wholly owned regional subsidiaries, has expressed a goal of increasing their share to a majority of American's regional flying over time. We have no guarantee that in the future our major airline partners will choose to enter into contracts with us, or renew their existing agreements with us, instead of operating their own regional jets, allocating flying to their captive regional airlines or entering into relationships with competing regional airlines. A decision by American or United to phase out or limit our capacity purchase agreements or to enter into similar agreements with our competitors could have a material adverse effect on our business, financial condition or results of operations. We may be limited from expanding our flying within our major airline partners' flight systems and there are constraints on our ability to provide services to airlines other than American and United. Additional growth opportunities within our major airline partners' flight systems are limited by various factors, including a limited number of independent regional aircraft that each such major airline partner can operate in its regional network due to "scope" clauses in the current collective bargaining agreements with their pilots that restrict the number and size of regional jets that may be operated in their flight systems not flown by their pilots. Except as contemplated by our existing capacity purchase agreements, we cannot be sure that our major airline partners will contract with us to fly any additional aircraft. We may not have additional growth opportunities, or may agree to modifications to our capacity purchase agreements that reduce certain benefits to us in order to obtain additional aircraft, or for other reasons. Given the competitive nature of the airline industry, we believe limited growth opportunities may result in competitors accepting reduced margins and less favorable contract terms in order to secure new or additional capacity purchase operations. Even if we are offered growth opportunities by our major airline partners, those opportunities may involve economic terms or financing commitments that are unacceptable to us. Additionally, our major airline partners may reduce the number of regional jets in their system by not renewing or extending existing flying arrangements with regional operators or transitioning those flying arrangements to their own captive regional carriers. Any one or more of these factors may reduce or eliminate our ability to expand our flight operations with our existing major airline partners. Additionally, our capacity purchase agreements limit our ability to provide regional flying services to other airlines in certain major airport hubs of American and United. These restrictions may make us a less attractive partner to other major airlines whose regional flying needs do not align with our geographical restrictions. We have a significant amount of debt and other contractual obligations and that could impair our liquidity and thereby harm our business, results of operations and financial condition. The airline business is capital intensive and, as a result, we are highly leveraged. As of September 30, 2019, we had approximately $858.1 million in total long-term debt including $8.5 million of capital lease obligations. Substantially all of our long-term debt was incurred in connection with the acquisition of aircraft and aircraft engines. We also have significant long-term lease obligations primarily relating to our aircraft fleet. These leases are classified as operating leases and are therefore not reflected in our consolidated balance sheets. During our fiscal years ended September 30, 2019, 2018 and 2017, our principal debt service payments totaled $244.1 million, $222.2 million and $153.0 million, respectively, and our principal aircraft lease payments totaled approximately $100.4 million, $64.6 million and $107.0 million, respectively. We have significant lease obligations with respect to our aircraft, which aggregated to approximately $142.6 million and $207.9 million at September 30, 2019 and 2018, respectively. At September 30, 2019, we had 18 aircraft under lease (excluding aircraft leased from United), with an average remaining term of 4.5 years. As of September 30, 2019, future minimum lease payments due under all long-term operating leases were approximately $155.4 million and debt service obligations were $1,016.4 million, respectively, including capital lease obligations. 16 We are subject to various financial covenants under our financing agreements and leases with, among others, CIT Bank, N.A. ("CIT"), Export Development Canada ("EDC") and RASPRO Trust 2005, as pass-through trust ("RASPRO") that are typical for credit facilities and leases of this size, type, and tenor. Our ability to make additional borrowings under our credit facility depends upon satisfaction of these covenants. Our ability to comply with these covenants and requirements may be affected by events beyond our control. Our failure to comply with obligations under our credit facility could result in an event of default under the facilities. A default, if not cured or waived, could prohibit us from obtaining further loans under our credit facilities and permit the lenders thereunder to accelerate payment of their loans. In addition, the lenders would have the right to proceed against the collateral we granted to them, which consists of substantially all of our assets. If our debt is accelerated, we cannot be certain that we will have funds available to pay the accelerated debt or that we will have the ability to refinance the accelerated debt on terms favorable to us, or at all. If we could not repay or refinance the accelerated debt, we could be insolvent and could seek to file for bankruptcy protection. Any such default, acceleration, or insolvency would likely have a material and adverse effect on our business. See "We are required to comply with certain ongoing financial and other covenants under certain credit facilities, and if we fail to meet those covenants or otherwise suffer a default thereunder, our lenders may accelerate the payment of such indebtedness" for a discussion of our financial and other covenants. We cannot assure you that our operations will generate sufficient cash flow to make our required payments, or that we will be able to obtain financing to acquire additional aircraft or make other capital expenditures necessary for expansion. Our ability to pay the high level of fixed costs associated with our contractual obligations will depend on our operating performance, cash flow and our ability to secure adequate financing, which will in turn depend on, among other things, the success of our current business strategy, the U.S. economy, availability and cost of financing, as well as general economic and political conditions and other factors that are, to some extent, beyond our control. The amount of our fixed obligations could have a material adverse effect on our business, results of operations and financial condition and could: (cid:3) (cid:3) require that a substantial portion of our cash flow from operations be used for operating lease and maintenance reserve payments, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes; limit our ability to obtain additional financing to support our expansion plans and for working capital and other purposes on acceptable terms or at all; (cid:3) make it more difficult for us to pay our other obligations as they become due during adverse general economic and market industry conditions because any related decrease in revenues could cause us to not have sufficient cash flows from operations to make our scheduled payments; and (cid:3) reduce our flexibility in planning for, or reacting to, changes in our business and the airline industry and, consequently, place us at a competitive disadvantage to our competitors with lower fixed payment obligations. Additionally, a failure to pay our operating leases, debt or other fixed cost obligations or a breach of our contractual obligations could result in a variety of further adverse consequences, including the exercise of remedies by our creditors and lessors. In such a situation, it is unlikely that we would be able to cure our breach, fulfill our obligations, make required lease payments or otherwise cover our fixed costs, which would have a material adverse effect on our business, results of operations and financial condition. We are required to comply with certain ongoing financial and other covenants under certain credit facilities, and if we fail to meet those covenants or otherwise suffer a default thereunder, our lenders may accelerate the payment of such indebtedness. Under (i) the credit and guaranty agreement with CIT ("CIT Revolving Credit Facility"), we are required to comply with a minimum consolidated interest and rental coverage ratio at the end of each fiscal quarter during the term of such credit facility, (ii) a credit agreement with EDC, we are required to comply with a minimum fixed charge coverage ratio at the end of each fiscal quarter during the term of such credit facility, and (iii) the aircraft lease facility ("RASPRO Lease Facility") with RASPRO we are required to comply with minimum current ratio and debt ratio covenants and a minimum available cash covenant until all amounts outstanding thereunder have been paid in full. 17 Failure to comply with the terms of these credit facilities and financing arrangements and the ongoing financial and other covenants thereunder would result in an event of default (as defined in the applicable credit facility and financing agreement) and, to the extent the applicable lenders so elect, an acceleration of our existing indebtedness following the expiration of any applicable cure periods, causing such debt to be immediately due and payable. Acceleration of such indebtedness would also trigger cross-default clauses under our other indebtedness. It could also result in the termination of all commitments to extend further credit under the CIT Revolving Credit Facility. We currently do not have sufficient liquidity to repay all of our outstanding debt in full if such debt were accelerated. If we are unable to pay our debts as they come due, or obtain waivers for such payments, our secured lenders could foreclose on any of our assets securing such debt. These events could materially adversely affect our business, results of operations and financial condition. The residual value of our owned aircraft may be less than estimated in our depreciation policies. As of September 30, 2019, we had approximately $1,273.6 million of property and equipment and related assets, net of accumulated depreciation, of which, $1,061.1 million relates to owned aircraft. In accounting for these long lived assets, we make estimates about the expected useful lives of the assets, the expected residual values of certain of these assets, and the potential for impairment based on the fair value of the assets and the cash flows they generate. Factors indicating potential impairment include, but are not limited to, significant decreases in the market value of the long lived assets, a significant change in the condition of the long lived assets and operating cash flow losses associated with the use of the long lived assets. In the event the estimated residual value of any of our aircraft types is determined to be lower than the residual value assumptions used in our depreciation policies, the applicable aircraft type in our fleet may be impaired and may result in a material reduction in the book value of applicable aircraft types we operate or we may need to prospectively modify our depreciation policies. An impairment on any of the aircraft types we operate or an increased level of depreciation expense resulting from a change to our depreciation policies could result in a material negative impact to our financial results. The amounts we receive under our capacity purchase agreements may be less than the corresponding costs we incur. Under our capacity purchase agreements with American and United, a portion of our compensation is based upon pre- determined rates typically applied to production statistics (such as departures and block hours flown). The primary operating costs intended to be compensated by the pre-determined rates include labor costs, including crew training costs, certain aircraft maintenance expenses and overhead costs. During our fiscal year ended September 30, 2019, approximately $37.2 million, or 5.8%, of our operating costs under our capacity purchase agreements were pass-through costs, excluding fuel which is paid directly to suppliers by our major airline partners. If our operating costs for labor, aircraft maintenance and overhead costs exceed the compensation earned from our pre-determined rates under our revenue-guarantee arrangements, our financial position and operating results will be negatively affected. Strikes, labor disputes and increased unionization of our workforces may adversely affect our ability to conduct our business and reduce our profitability. As of September 30, 2019, approximately 75.6% of our workforce was represented by labor unions, including the Air Line Pilots Association, International ("ALPA") and the Association of Flight Attendants ("AFA"). On July 13, 2017, our pilots, represented by the ALPA, ratified a new four-year collective bargaining agreement. Similarly, on October 1, 2017, our flight attendants, represented by the AFA, ratified a new four-year collective bargaining agreement. The terms and conditions of our future collective bargaining agreements may be affected by the results of collective bargaining negotiations at other airlines that may have a greater ability, due to larger scale, greater efficiency or other factors, to bear higher costs than we can. In addition, if we are unable to reach agreement with any of our unionized work groups in future negotiations regarding the terms of their collective bargaining agreements, we may be subject to work interruptions, stoppages or shortages. We may also become subject to additional collective bargaining agreements in the future as non- unionized workers may unionize. We are also subject to various ongoing employment disputes outside of the collective bargaining agreements. We consider these to not be material, but any current or future dispute could become material. Relations between air carriers and labor unions in the United States are governed by the RLA. Under the RLA, collective bargaining agreements generally contain "amendable dates" rather than expiration dates, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the NMB. This process continues until either the parties have reached agreement on a new collective bargaining agreement, or the parties have been released to "self-help" by the NMB. In most circumstances, the RLA prohibits strikes; however, after release by the NMB, carriers and unions are free to engage in self-help measures such as lockouts and strikes. 18 Any strike, labor dispute or increased unionization among our employees could disrupt our operations, reduce our profitability or interfere with the ability of our management to focus on executing our business strategies. For example, if a labor strike were to continue for several consecutive days, United may have cause to terminate our United Capacity Purchase Agreement. As a result, our business, results of operations and financial condition may be materially adversely affected. We face tail risk in that we have aircraft lease commitments that extend beyond our existing capacity purchase agreement contractual terms on certain aircraft. We currently have aircraft with leases extending past the term of their corresponding capacity purchase agreement with an aggregate exposure of approximately $32.2 million. We may not be successful in extending the flying contract terms on these aircraft with our major airline partners. In that event, we intend to pursue alternative uses for those aircraft over the remaining portions of their leases including, but not limited to, operating the aircraft with another major airline under a negotiated capacity purchase agreement, subleasing the aircraft to another operator or marketing them for sale. Additionally, we may negotiate an early lease return agreement with an aircraft's lessor. In connection with this, we may incur cash and non-cash early lease termination costs that would negatively impact our operations and financial condition. Additionally, if we are unable to extend a flying contract with an existing major airline partner but reach an agreement to place an aircraft into service with a different major airline partner, we likely will incur inefficiencies and incremental costs, such as changing the aircraft livery, which would negatively impact our financial results. We may incur substantial maintenance costs as part of our leased aircraft return obligations. Our aircraft lease agreements contain provisions that require us to return aircraft airframes and engines to the lessor in a specified condition or pay an amount to the lessor based on the actual return condition of the equipment. These lease return costs are recorded in the period in which they are incurred. We estimate the cost of maintenance lease return obligations and accrue such costs over the remaining lease term when the expense is probable and can be reasonably estimated. Any unexpected increase in maintenance return costs may negatively impact our financial position and results of operations. We may become involved in litigation that may materially adversely affect us. From time to time, we may become involved in various legal proceedings relating to matters incidental to the ordinary course of our business, including employment, commercial, product liability, class action, whistleblower and other litigation and claims, and governmental and other regulatory investigations and proceedings. Such matters can be time-consuming, divert management's attention and resources, cause us to incur significant expenses or liability and/or require us to change our business practices. Because of the potential risks, expenses and uncertainties of litigation, we may, from time to time, settle disputes, even where we believe that we have meritorious claims or defenses. Because litigation is inherently unpredictable, we cannot assure you that the results of any of these actions will not have a material adverse effect on our business, results of operations and financial condition. Disagreements regarding the interpretation of our capacity purchase agreements with our major airline partners could have an adverse effect on our operating results and financial condition. To the extent that we experience disagreements regarding the interpretation of our capacity purchase or other agreements, we will likely expend valuable management time and financial resources in our efforts to resolve those disagreements. Those disagreements may result in litigation, arbitration, settlement negotiations or other proceedings. Furthermore, there can be no assurance that any or all of those proceedings, if commenced, would be resolved in our favor or that we would be able to exercise sufficient leverage in any proceeding relative to our major airline partner to achieve a favorable outcome. An unfavorable result in any such proceeding could have adverse financial consequences or require us to modify our operations. Such disagreements and their consequences could have an adverse effect on our operating results and financial condition. We rely on third-party suppliers as the sole manufacturers of our aircraft and aircraft engines. We depend upon Bombardier and Embraer as the sole manufacturers of our aircraft and GE as the sole manufacturer of our aircraft engines. Our operations could be materially and adversely affected by the failure or inability of Bombardier, Embraer or GE to provide sufficient parts or related maintenance and support services to us in a timely manner, or the interruption of our flight operations as a result of unscheduled or unanticipated maintenance requirements for our aircrafts or engines. 19 Maintenance costs will likely increase as the age of our regional jet fleet increases. The average age of our E-175, CRJ-900 and CRJ-700 type aircraft is approximately 3.9, 13.0 and 15.7 years, respectively. We have incurred relatively low maintenance expenses on our E-175 aircraft because most of the parts are under multi-year warranties and a limited number of heavy airframe checks and engine overhauls have occurred. Our maintenance costs will increase significantly, both on an absolute basis and as a percentage of our operating expenses, as our fleet ages and the E-175 warranties expire. In addition, because our current aircraft were acquired over a relatively short period of time, significant maintenance events scheduled for these aircraft will occur at roughly the same intervals, meaning we will incur our most expensive scheduled maintenance obligations across our present fleet at approximately the same time. These more significant maintenance activities result in out-of-service periods during which aircraft are dedicated to maintenance activities and unavailable for flying under our capacity purchase agreements. Any unexpected increase in our maintenance costs as our fleet ages or decreased revenues resulting from out-of-service periods could have an adverse effect on our cash flows, operating results and financial condition. If we face problems with any of our third-party service providers, our operations could be adversely affected. Our reliance upon others to provide essential services on behalf of our operations may limit our ability to control the efficiency and timeliness of contract services. We have entered into agreements with contractors to provide various facilities and services required for our operations, including aircraft maintenance, ground facilities and IT services, and expect to enter into additional similar agreements in the future. In particular, we rely on AAR and Aviall to provide fixed- rate parts procurement and component overhaul services for our aircraft fleet and GE to provide engine support. Our agreements with AAR, and other service providers, are subject to termination after notice. If our third-party service providers terminate their contracts with us, or do not provide timely or consistently high-quality service, we may not be able to replace them in a cost-efficient manner or in a manner timely enough to support our operational needs, which could have a material adverse effect on our business, financial condition and results of operations. In addition, our operations could be materially and adversely affected by the failure or inability of AAR, Aviall or GE to provide sufficient parts or related maintenance and support services to us in a timely manner. Regulatory changes or tariffs could negatively impact our business and financial condition. We import a substantial portion of the equipment we need. For example, the sole manufacturers of our aircraft, Bombardier and Embraer, are headquartered in Canada and Brazil, respectively. We cannot predict the impact of potential regulatory changes or action by U.S. regulatory agencies, including the potential impact of tariffs or changes in international trade treaties on the cost and timing of parts and aircraft. Our business may be subject to additional costs as a result of potential regulatory changes, which could have an adverse effect on our operations and financial results. The issuance of operating restrictions applicable to one of the fleet types we operate could negatively impact our business and financial condition. We rely on a limited number of aircraft types, including CRJ-700, CRJ-900 and E-175 aircraft. The issuance of FAA or manufacturer directives restricting or prohibiting the use of the aircraft types we operate could negatively impact our business and financial results. If we have a failure in our technology or security breaches of our information technology infrastructure our business and financial condition may be adversely affected. The performance and reliability of our technology, and the technology of our major airline partners, are critical to our ability to compete effectively. Any internal technological error or failure or large scale external interruption in the technological infrastructure we depend on, such as power, telecommunications or the internet, may disrupt our internal network. Any individual, sustained or repeated failure of our technology or that of our major airline partners could impact our ability to conduct our business, lower the utilization of our aircraft and result in increased costs. Our technological systems and related data, and those of our major airline partners, may be vulnerable to a variety of sources of interruption due to events beyond our control, including natural disasters, terrorist attacks, telecommunications failures, computer viruses, hackers and other security issues. 20 In addition, as a part of our ordinary business operations, we collect and store sensitive data, including personal information of our employees and information of our major airline partners. Our information systems are subject to an increasing threat of continually evolving cybersecurity risks. Unauthorized parties may attempt to gain access to our systems or information through fraud or other means of deception. The methods used to obtain unauthorized access, disable or degrade service or sabotage systems are constantly evolving, and may be difficult to anticipate or to detect for long periods of time. We may not be able to prevent all data security breaches or misuse of data. The compromise of our technology systems resulting in the loss, disclosure, misappropriation of, or access to, employees' or business partners' information could result in legal claims or proceedings, liability or regulatory penalties under laws protecting the privacy of personal information, disruption to our operations and damage to our reputation, any or all of which could adversely affect our business and financial condition. Our business could be materially adversely affected if we lose the services of our key personnel. Our success depends to a significant extent upon the efforts and abilities of our senior management team and key financial and operating personnel. In particular, we depend on the services of Jonathan G. Ornstein, our Chairman and Chief Executive Officer, and Michael J. Lotz, our President and Chief Financial Officer. Competition for highly qualified personnel is intense, and the loss of any executive officer, senior manager, or other key employee without an adequate replacement, or the inability to attract new qualified personnel, could have a material adverse effect on our business, results of operations and financial condition. We are subject to various environmental and noise laws and regulations, which could have a material adverse effect on our business, results of operations and financial condition. We are subject to increasingly stringent federal, state, local and foreign laws, regulations and ordinances relating to the protection of the environment and noise, including those relating to emissions to the air, discharges (including storm water discharges) to surface and subsurface waters, safe drinking water and the use, management, disposal and release of, and exposure to, hazardous substances, oils and waste materials. We are or may be subject to new or proposed laws and regulations that may have a direct effect (or indirect effect through our third-party specialists or airport facilities at which we operate) on our operations. In addition, U.S. airport authorities are exploring ways to limit de-icing fluid discharges. Any such existing, future, new or potential laws and regulations could have an adverse impact on our business, results of operations and financial condition. Similarly, we are subject to environmental laws and regulations that require us to investigate and remediate soil or groundwater to meet certain remediation standards. Under certain laws, generators of waste materials, and current and former owners or operators of facilities, can be subject to liability for investigation and remediation costs at locations that have been identified as requiring response actions. Liability under these laws may be strict, joint and several, meaning that we could be liable for the costs of cleaning up environmental contamination regardless of fault or the amount of wastes directly attributable to us. Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited. As of September 30, 2019, we had aggregate federal and state net operating loss carryforwards of approximately $478.3 million and $228.3 million, which expire in fiscal years 2027-2037 and 2020-2039, respectively, with approximately $0.9 million of state net operating loss carryforwards that expired in 2019 which had a full valuation allowance against them. Our unused losses generally carry forward to offset future taxable income, if any, until such unused losses expire. We may be unable to use these losses to offset income before such unused losses expire. However, US federal net operating losses generated in fiscal years 2018 and forward are not subject to expiration and net operating losses generated in fiscal 2019 and forward are only available to offset eighty percent of taxable income each year due to changes in tax law attributable to the passage of Tax Cuts and Jobs Act. In addition, if a corporation undergoes an "ownership change" (generally defined as a greater than 50% cumulative change in the equity ownership of certain shareholders over a rolling three-year period) under Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"), the corporation's ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset future taxable income or taxes may be limited. We have experienced ownership changes in the past and may experience ownership changes as a result of future changes in our stock ownership (some of which changes may not be within our control). This, in turn, could materially reduce or eliminate our ability to use our losses or tax attributes to offset future taxable income or tax and have an adverse effect on our future cash flows. See "—Our corporate charter limits certain transfers of our stock, which limits are intended to preserve our ability to use our net operating loss carryforwards, and these limits could have an effect on the market price of our common stock." 21 We may not be able to successfully implement our growth strategy. Our growth strategy includes, among other things, providing regional flying to other airlines and/or entering into the cargo and express shipping business. We face numerous challenges in implementing our growth strategy, including our ability to: (cid:3) (cid:3) provide regional flying to other airlines with hub cities that overlap with our existing airline partners; and enter into relationships with third parties to carry their cargo on terms that are acceptable to us. Our capacity purchase agreements limit our ability to provide regional flying services to other airlines in certain major airport hubs of American and United. These restrictions may make us a less attractive partner to other major airlines whose regional flying needs do not align with our geographical restrictions. The potential benefits of entering the air cargo and express shipping sector will depend substantially on our ability to enter into relationships with integrated logistics companies and transition our existing business strategies into a new sector. We may be unsuccessful in entering into relationships with integrated logistics companies to carry cargo on terms that are acceptable to us. Additionally, our ability to transition our existing business strategies into a new sector may be costly, complex and time-consuming, and our management will have to devote substantial time and resources to such effort. Should we transition into this new sector, we may experience difficulties or delays in securing gate access and other airport services necessary to operate in the air cargo and express shipping sector. Our inability to successfully implement our growth strategies, could have a material adverse effect on our business, financial condition and results of operations and any assumptions underlying estimates of expected cost savings or expected revenues may be inaccurate. We may not be able to make opportunistic acquisitions should we elect to do so as part of our growth strategy. If we elect to pursue an acquisition, our ability to successfully implement this transaction would depend on a variety of factors, including the approval of our acquisition target's major airline partners, obtaining financing on acceptable terms and compliance with the restrictions contained in our debt agreements. If we need to obtain our lenders' consent prior to an acquisition, they may refuse to provide such consent or condition their consent on our compliance with additional restrictive covenants that limit our operating flexibility. Acquisition transactions involve risks, including those associated with integrating the operations or (as applicable) separately maintaining the operations, financial reporting, disparate technologies and personnel of acquired companies; managing geographically dispersed operations; the diversion of management's attention from other business concerns; unknown risks; and the potential loss of key employees. We may not successfully integrate any businesses we may acquire in the future and may not achieve anticipated revenue and cost benefits relating to any such transactions. Strategic transactions may be expensive, time consuming and may strain our resources. Strategic transactions may not be accretive to our earnings and may negatively impact our results of operations as a result of, among other things, the incurrence of debt, one-time write-offs of goodwill and amortization expenses of other intangible assets. In addition, strategic transactions that we may pursue could result in dilutive issuances of equity securities. Our ability to obtain financing or access capital markets may be limited. There are a number of factors that may limit our ability to raise financing or access capital markets in the future, including our significant debt and future contractual obligations, our liquidity and credit status, our operating cash flows, the market conditions in the airline industry, U.S. and global economic conditions, the general state of the capital markets and the financial position of the major providers of commercial aircraft financing. We cannot assure you that we will be able to source external financing for our planned aircraft acquisitions or for other significant capital needs, and if we are unable to source financing on acceptable terms, or unable to source financing at all, our business could be materially adversely affected. To the extent we finance our activities with additional debt, we may become subject to financial and other covenants that may restrict our ability to pursue our business strategy or otherwise constrain our growth and operations. Negative publicity regarding our customer service could have a material adverse effect on our business, results of operations and financial condition. Our business strategy includes the implementation of our major airline partners' brand and product in order to increase customer loyalty and drive future ticket sales. In addition, we also receive certain amounts under our United Capacity Purchase Agreement based upon the results of passenger satisfaction surveys. However, we may experience a high number of passenger complaints related to, among other things, our customer service. These complaints, together with delayed and cancelled flights, and other service issues, are reported to the public by the DOT. If we do not meet our major airline partners' expectations with respect to reliability and service, our and our major airline partners' brand and product could be negatively impacted, which could result in customers deciding not to fly with our major airline partners or with us. If we are unable to provide consistently high-quality customer service, it could have an adverse effect on our relationships with our major airline partners. 22 Risks associated with our presence in international emerging markets, including political or economic instability, and failure to adequately comply with existing legal requirements, may materially adversely affect us. Some of our target growth markets include countries with less developed economies, legal systems, financial markets and business and political environments are vulnerable to economic and political disruptions, such as significant fluctuations in gross domestic product, interest and currency exchange rates, civil disturbances, government instability, nationalization and expropriation of private assets, trafficking and the imposition of taxes or other charges by governments. The occurrence of any of these events in markets served by us now or in the future and the resulting instability may have a material adverse effect on our business, results of operations and financial condition. We emphasize compliance with all applicable laws and regulations and have implemented and continue to implement and refresh policies, procedures and certain ongoing training of our employees, third-party specialists and partners with regard to business ethics and key legal requirements; however, we cannot assure you that our employees, third-party specialists or partners will adhere to our code of ethics, other policies or other legal requirements. If we fail to enforce our policies and procedures properly or maintain adequate recordkeeping and internal accounting practices to record our transactions accurately, we may be subject to sanctions. In the event we believe or have reason to believe our employees, third-party specialists or partners have or may have violated applicable laws or regulations, we may incur investigation costs, potential penalties and other related costs which in turn may materially adversely affect our reputation and could have a material adverse effect on our business, results of operations and financial condition. Risks Related to Our Industry The airline industry is highly competitive and has undergone a period of consolidation and transition leaving fewer potential major airline partners. The airline industry is highly competitive. We compete primarily with other regional airlines, some of which are owned by or operated by major airlines. In certain instances, our competitors are larger than us and possess significantly greater financial and other resources than we do. The airline industry has undergone substantial consolidation, including the mergers between Alaska Airlines and Virgin America Inc. in 2016, American and US Airways in 2013, Southwest Airlines Co. and AirTran Airways in 2011, United and Continental Airlines in 2010 and Delta and Northwest Airlines in 2008. Any additional consolidation or significant alliance activity within the airline industry could further limit the number of potential partners with whom we could enter into capacity purchase agreements. We are subject to significant governmental regulation. All interstate air carriers, including us, are subject to regulation by the DOT, the FAA and other governmental agencies. Regulations promulgated by the DOT primarily relate to economic aspects of air service. The FAA requires operating, air worthiness and other certificates; approval of personnel who may engage in flight, maintenance or operation activities; record keeping procedures in accordance with FAA requirements; and FAA approval of flight training and retraining programs. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not have a material adverse effect on our operations. We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. A decision by the FAA to ground, or require time consuming inspections of or maintenance on, all or any of our aircraft for any reason may have a material adverse effect on our operations. In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations and require that we incur substantial on-going costs. Airlines are often affected by factors beyond their control including: air traffic congestion at airports; air traffic control inefficiencies; adverse weather conditions, such as hurricanes or blizzards; increased security measures; new travel related taxes or the outbreak of disease; any of which could have a material adverse effect on our business, results of operations and financial condition. Like other airlines, our business is affected by factors beyond our control, including air traffic congestion at airports, air traffic control inefficiencies, increased security measures, new travel-related taxes and fees, adverse weather conditions, natural disasters and the outbreak of disease. Factors that cause flight delays frustrate passengers and increase operating costs and decrease revenues, which in turn could adversely affect profitability. The federal government singularly controls all U.S. airspace, and airlines are completely dependent on the FAA to operate that airspace in a safe, efficient and affordable manner. The air traffic control system, which is operated by the FAA, faces challenges in managing the growing demand for U.S. air travel. U.S. and foreign air-traffic controllers often rely on outdated technologies that routinely overwhelm the system and compel airlines to fly inefficient, indirect routes resulting in delays. In addition, there are currently proposals before Congress that could potentially lead to the privatization of the United States' air traffic control system, which could adversely affect our business. Further, implementation of the Next Generation Air Transport System by the FAA would result in changes to aircraft routings and flight paths that could lead to increased noise complaints and lawsuits, resulting in increased costs. There are additional proposals before Congress that would treat a wide range of consumer protection issues, including, among other things, proposals to regulate seat size, which could increase the costs of doing business. 23 Adverse weather conditions and natural disasters, such as hurricanes, winter snowstorms or earthquakes, can cause flight cancellations or significant delays. Cancellations or delays due to adverse weather conditions or natural disasters, air traffic control problems or inefficiencies, breaches in security or other factors may affect us to a greater degree than other, larger airlines that may be able to recover more quickly from these events, and therefore could have a material adverse effect on our business, results of operations and financial condition to a greater degree than other air carriers. Any general reduction in airline passenger traffic could have a material adverse effect on our business, results of operations and financial condition. Terrorist activities or warnings have dramatically impacted the airline industry and will likely continue to do so. The terrorist attacks of September 11, 2001 and their aftermath have negatively impacted the airline industry in general, including our operations. If additional terrorist attacks are launched against the airline industry, there will be lasting consequences of the attacks, which may include loss of life, property damage, increased security and insurance costs, increased concerns about future terrorist attacks, increased government regulation and airport delays due to heightened security. We cannot provide any assurance that these events will not harm the airline industry generally or our operations or financial condition in particular. The occurrence of an aviation accident involving our aircraft would negatively impact our operations and financial condition. An accident or incident involving our aircraft could result in significant potential claims of injured passengers and others, as well as repair or replacement of a damaged aircraft and its consequential temporary or permanent loss from service. In the event of an accident, our liability insurance may not be adequate to offset our exposure to potential claims and we may be forced to bear substantial losses from the accident. Substantial claims resulting from an accident in excess of our related insurance coverage would harm our operational and financial results. Moreover, any aircraft accident or incident, even if fully insured, could cause a public perception that our operations are less safe or reliable than other airlines. An outbreak of a disease or similar public health threat could have a material adverse impact on our business, financial position and results of operations. An outbreak of a disease or similar public health threat that affects travel demand, travel behavior, or travel restrictions could have a material adverse impact on our business, financial condition and results of operations. Risks Related to Owning Our Common Stock The market price of our common stock may be volatile, which could cause the value of an investment in our stock to decline. The market price of our common stock may fluctuate substantially due to a variety of factors, many of which are beyond our control, including: (cid:3) (cid:3) announcements concerning our major airline partners, competitors, the airline industry or the economy in general; strategic actions by us, our major airline partners, or our competitors, such as acquisitions or restructurings; (cid:3) media reports and publications about the safety of our aircraft or the aircraft type we operate; (cid:3) (cid:3) (cid:3) (cid:3) (cid:3) (cid:3) new regulatory pronouncements and changes in regulatory guidelines; announcements concerning the availability of the type of aircraft we use; significant volatility in the market price and trading volume of companies in the airline industry; changes in financial estimates or recommendations by securities analysts or failure to meet analysts' performance expectations; sales of our common stock or other actions by insiders or investors with significant shareholdings, including sales by our principal shareholders; and general market, political and other economic conditions. The stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of particular companies. Broad market fluctuations may materially adversely affect the trading price of our common stock. 24 In the past, shareholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Any similar litigation against us could result in substantial costs, divert management's attention and resources and have a material adverse effect on our business, results of operations and financial condition. If securities or industry analysts do not publish research or reports about our business or publish negative reports about our business, our stock price and trading volume could decline. The trading market for our common stock depends in part on the research and reports that securities and industry analysts may publish about us or our business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, the trading price of our common stock would likely decline. If one or more of these analysts ceases to cover our company or fails to publish reports on us regularly, demand for our stock could decrease, which may cause the trading price of our common stock and the trading volume of our common stock to decline. The value of our common stock may be materially adversely affected by additional issuances of common stock by us or sales by our principal shareholders. Any future issuances or sales of our common stock by us will be dilutive to our existing common shareholders. Sales of substantial amounts of our common stock in the public or private market, a perception in the market that such sales could occur, or the issuance of securities exercisable or convertible into our common stock, could adversely affect the prevailing price of our common stock. The value of our common stock may be materially adversely affected by additional issuances of common stock underlying our outstanding warrants. As of September 30, 2019, we had outstanding warrants to purchase an aggregate of 3,600,953 shares of our common stock, all of which were originally issued to non-U.S. citizens who were claimholders in our bankruptcy proceedings in order to maintain compliance with restrictions imposed by federal law on foreign ownership of U.S. airlines. Any future warrant exercises by our existing warrant holders will be dilutive to our existing common shareholders. All of the shares of common stock issuable upon exercise of our warrants will be freely tradeable without restrictions or further registration under the Securities Act of 1933, as amended (the "Securities Act"). Sales of substantial amounts of our common stock in the public or private market, a perception in the market that such sales could occur, or the issuance of securities exercisable or convertible into our common stock, could adversely affect the prevailing price of our common stock. Provisions in our charter documents might deter acquisition bids for us, which could adversely affect the price of our common stock. Our second amended and restated articles of incorporation and amended and restated bylaws contain provisions that, among other things: (cid:3) (cid:3) (cid:3) (cid:3) (cid:3) authorize our Board of Directors, without shareholder approval, to designate and fix the voting powers, designations, preferences, limitations, restrictions and relative rights of one or more series of preferred stock and to issue shares of one or more series of preferred stock so designated, or rights to acquire such preferred stock, that could dilute the interest of, or impair the voting power of, holders of our common stock and could also have the effect of discouraging, delaying or preventing a change of control; establish advance notice procedures that shareholders must comply with in order to nominate candidates to our Board of Directors and propose matters to be brought before an annual or special meeting of our shareholders, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer's own slate of directors or otherwise attempting to obtain control of our company; authorize a majority of our Board of Directors to appoint a director to fill a vacancy created by the expansion of our Board of Directors or the resignation, death or removal of a director, which may prevent shareholders from being able to fill vacancies on our Board of Directors; restrict the number of directors constituting our Board of Directors to within a set range, and give our Board of Directors exclusive authority to increase or decrease the number of directors within such range, which may prevent shareholders from being able to fill vacancies on our Board of Directors; and restrict the ability of shareholders to call special meetings of shareholders. 25 Our corporate charter includes provisions limiting ownership by non-U.S. citizens. To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, our second amended and restated articles of incorporation restrict the ownership and voting of shares of our common stock by people and entities who are not "citizens of the United States" as that term is defined in 49 U.S.C. § 40102(a). That statute defines "citizen of the United States" as, among other things, a U.S. corporation, of which the president and at least two-thirds of the board of directors and other managing officers are individuals who are citizens of the United States, which is under the actual control of citizens of the United States and in which at least 75% of the voting interest is owned or controlled by persons who are citizens of the United States. Our second amended and restated articles of incorporation prohibit any non-U.S. citizen from owning or controlling more than 24.9% of the aggregate votes of all outstanding shares of our common stock or 49.0% of the total number of outstanding shares of our capital stock. The restrictions imposed by the above-described ownership caps are applied to each non-U.S. citizen in reverse chronological order based on the date of registration on our foreign stock record. At no time may shares of our capital stock held by non-U.S. citizens be voted unless such shares are reflected on the foreign stock record. The voting rights of non-U.S. citizens having voting control over any shares of our capital stock are subject to automatic suspension to the extent required to ensure that we are in compliance with applicable law. In the event any transfer or issuance of shares of our capital stock to a non-U.S. citizen would result in non-U.S. citizens owning more than the above-described cap amounts, such transfer or issuance will be void and of no effect. As of September 30, 2019, we had outstanding warrants to purchase 3,600,953 shares of our common stock with an exercise price of $0.004 per share. We are currently in compliance with all applicable foreign ownership restrictions. Our corporate charter limits certain transfers of our stock, which limits are intended to preserve our ability to use our net operating loss carryforwards, and these limits could have an effect on the market price and liquidity of our common stock. To reduce the risk of a potential adverse effect on our ability to use our net operating loss carryforwards for federal income tax purposes, our second amended and restated articles of incorporation prohibit the transfer of any shares of our capital stock that would result in (i) any person or entity owning 4.75% or more of our then-outstanding capital stock, or (ii) an increase in the percentage ownership of any person or entity owning 4.75% or more of our then-outstanding capital stock. These transfer restrictions expire upon the earliest of (i) the repeal of Section 382 of the Code or any successor statute if our Board of Directors determines that such restrictions are no longer necessary to preserve our ability to use our net operating loss carryforwards, (ii) the beginning of a fiscal year to which our Board of Directors determines that no net operating losses may be carried forward, or (iii) such other date as determined by our Board of Directors. These transfer restrictions apply to the beneficial owner of the shares of our capital stock. The clients of an investment advisor are treated as the beneficial owners of stock for this purpose if the clients have the right to receive dividends, if any, the power to acquire or dispose of the shares of our capital stock, and the right to proceeds from the sale of our capital stock. Certain transactions approved by our Board of Directors, such as mergers and consolidations meeting certain requirements set forth in our articles of incorporation, are exempt from the above-described transfer restrictions. Our Board of Directors also has the ability to grant waivers, in its discretion, with respect to transfers of our stock that would otherwise be prohibited. The transfer restrictions contained in our second amended and restated articles of incorporation may impair or prevent a sale of common stock by a shareholder and may adversely affect the price at which a shareholder can sell our common stock. In addition, this limitation may have the effect of delaying or preventing a change in control of the Company, creating a perception that a change in control cannot occur or otherwise discouraging takeover attempts that some shareholders may consider beneficial, which could also adversely affect the market price of our common stock. We cannot predict the effect that this provision in our second amended and restated articles of incorporation may have on the market price of our common stock. 26 We currently do not intend to pay dividends on our common stock and, consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates. We have not historically paid dividends on shares of our common stock and do not expect to pay dividends on such shares in the foreseeable future. Additionally, our RASPRO Lease Facility and GECAS Lease Facility contain restrictions that limit our ability to or prohibit us from paying dividends to holders of our common stock. Any future determination to pay dividends will be at the discretion of our Board of Directors and will depend on our results of operations, financial condition, capital requirements, restrictions contained in current or future leases and financing instruments, business prospects and such other factors as our Board of Directors deems relevant, including restrictions under applicable law. Consequently, your only opportunity to achieve a positive return on your investment in us will be if the market price of our common stock appreciates. We are an "emerging growth company," and the reduced disclosure and regulatory requirements applicable to "emerging growth companies" may make our common stock less attractive to investors. We qualify as an "emerging growth company" as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and therefore we may take advantage of reduced disclosure and regulatory requirements that are otherwise generally applicable to public companies. As an emerging growth company: (cid:3) we are not required to obtain an attestation and report from our independent registered public accounting firm on our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act; (cid:3) we may present reduced disclosure regarding executive compensation in our periodic reports and proxy statements; and (cid:3) we are not required to hold nonbinding advisory shareholder votes on executive compensation or golden parachute arrangements. We may take advantage of these reduced requirements until we are no longer an "emerging growth company," which will occur upon the earliest of (i) the last day of our fiscal year following the fifth anniversary of our IPO (i.e. September 30, 2023), (ii) the last day of the first fiscal year in which our annual gross revenue is $1.07 billion or more, (iii) the date on which we have, during the previous rolling three-year period, issued more than $1.0 billion in non-convertible debt securities and (iv) the date on which we are deemed to be a "large accelerated filer" as defined in the Exchange Act. Investors may find our common stock less attractive or our company less comparable to certain other public companies because we will rely on these reduced requirements. In addition, the JOBS Act permits an "emerging growth company" to take advantage of an extended transition period to comply with new or revised accounting standards. This effectively permits the delayed adoption of certain accounting standards until those standards would otherwise apply to private companies. However, we are electing to "opt out" of such extended transition period and, as a result, we will comply with new or revised accounting standards on the dates for which compliance is required for non-emerging growth companies. This election is irrevocable. The requirements of being a public company may strain our resources, increase our operating costs, divert management's attention and affect our ability to attract and retain qualified board members or executive officers. We became a public company in August 2018. As a result, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the listing requirements of The Nasdaq Global Select Market, and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming, or costly, and increase demand on our systems and resources, particularly after we are no longer an "emerging growth company." The Exchange Act requires, among other things, that we file annual, quarterly, and current reports with respect to our business and results of operations. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. To maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management's attention may be diverted from other business concerns, which could harm our business and results of operations. We will need to hire additional employees or engage outside consultants to comply with these requirements, increasing our costs and expenses. 27 In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time- consuming. These laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management's time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations, and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us, and our business may suffer. Being a public company has also increased the cost of our director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs in the future to obtain similar coverage. These factors could also make it more difficult for us to attract and retain qualified members of our Board of Directors, particularly to serve on our board committees, and qualified executive officers. As a result of disclosure of information in filings required of a public company, our business and financial condition will become more visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business and results of operations could suffer, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and harm our business, financial condition and results of operations. We are required to assess our internal control over financial reporting on an annual basis, and any future adverse findings from such assessment could result in a loss of investor confidence in our financial reports, result in significant expenses to remediate any internal control deficiencies and have a material adverse effect on our business, results of operations and financial condition. We are required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting for our fiscal year ended September 30, 2019 and each subsequent year. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting. Our independent registered public accounting firm is not required to attest to the effectiveness of our internal control over financial reporting until our first annual report required to be filed with the SEC following the later of the date we are deemed to be an "accelerated filer" or a "large accelerated filer," each as defined in the Exchange Act, or the date we are no longer an "emerging growth company," as defined in the JOBS Act. We are required to disclose, to the extent material, changes made in our internal control over financial reporting on a quarterly basis. To comply with the requirements of being a public company, we may need to undertake various actions, such as implementing new internal controls and procedures and hiring accounting or internal audit staff. Management assessed the effectiveness of our internal control over financial reporting at September 30, 2019. In making these assessments, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on our assessments and those criteria, management determined that we maintained effective internal control over financial reporting as of September 30, 2019. In future periods, if we fail to achieve and maintain an effective internal control environment, it could result in material misstatements in our financial statements and failure to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information and adversely impact our stock price. ITEM 1B. UNRESOLVED STAFF COMMENTS None 28 ITEM 2. PROPERTIES Flight Equipment As of September 30, 2019, our fleet available for scheduled service consisted of the following aircraft: Scheduled Average Aircraft Type E-175 Regional Jet CRJ-900 Regional Jet CRJ-700 Regional Jet CRJ-200 Regional Jet Total Owned Leased 42 16 2 — 60 18 48 18 1 85 Flight Passenger Cruising Average Capacity Range (miles) Speed (mph) Age (years) 3.9 13.0 15.7 25.7 2,100 1,500 1,600 1,500 76 76/79 70 50 530 530 530 530 Total 60 64 20 1 145 Several factors may impact our fleet size throughout our fiscal 2019 and thereafter, including contract expirations, lease expirations, growth opportunities and opportunities to transition to an alternative airline partner. Below is our fiscal 2019 outlook on our fleet by aircraft type. Our actual future fleet size and mix of aircraft types will likely vary, and may vary materially, from our current fleet size. (cid:3) CRJ-900s – As of September 30, 2019, we operated 62 CRJ-900 aircraft under our American Capacity Purchase Agreement and two (2) CRJ-900 aircraft as operational spares. Our American Capacity Purchase Agreement will expire with respect to different tranches of aircraft between 2021 and 2025, unless otherwise extended or amended. American has the option to unilaterally extend the term of our American Capacity Purchase Agreement up to three times for one year each (on the same terms) by providing us prior written notice. Our American Capacity Purchase Agreement is subject to termination prior to that date, subject to our right to cure, in various circumstances. (cid:3) CRJ-700s – As of September 30, 2019, we operated twenty (20) CRJ-700 aircraft under our United Capacity Purchase Agreement. Subject to certain early termination rights, as part of the amended and restated United Capacity Purchase Agreement, United has elected to have us 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 between May 2020 and Dec 2020. 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. In addition, United has right to purchase the CRJ 700 aircraft at the then fair market value. (cid:3) E-175s - As of September 30, 2019, we operated 60 E-175 aircraft under our United Capacity Purchase Agreement. As part of our amended and restated United Capacity Purchase Agreement, we agreed to extend the term of 42 of our E-175 aircraft (owned by United) for an additional five (5) years which will now expire between 2024 and 2028, subject to United's early termination rights. United also has the right to extend the term of these aircraft under our United Capacity Purchase Agreement for four additional three-years. In addition, 18 of the E-175 aircraft (owned by us) operating under our United Capacity Purchase Agreement expire between January 2028 and November 2028, subject to United's early termination rights. 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 90 days notice. (cid:3) CRJ-200s – As of September 30, 2019, we operated one CRJ-200 aircraft as an operational spare. Facilities In addition to aircraft we have office and maintenance facilities to support our operations. Each of our facilities are summarized in the following table: Type Corporate Headquarters Training Center Parts/Stores Hangar Office, Hangar and Warehouse Office, Hangar Hangar Hangar Hangar Location Phoenix, Arizona Phoenix, Arizona Phoenix, Arizona Phoenix, Arizona El Paso, Texas Dallas, Texas Houston, Texas Louisville, Kentucky Dulles, Washington 29 Ownership Leased Leased Leased Leased Leased Leased Leased Leased Leased Approximate Square Feet 33,770 23,783 12,000 22,467 31,292 30,440 74,524 26,762 28,451 Our corporate headquarters and training facilities in Phoenix, Arizona are subject to long-term leases expiring on November 30, 2025 and May 31, 2025 respectively. We believe our facilities are suitable and adequate for our current and anticipated needs. ITEM 3. LEGAL PROCEEDINGS We are subject to certain legal actions which we consider routine to our business activities. As of September 30, 2019, our management believed, after consultation with legal counsel, that the ultimate outcome of such legal matters was not likely to have a material adverse effect on our financial position, liquidity or results of operations. ITEM 4. MINE SAFETY DISCLOSURES The disclosure required by this item is not applicable. 30 PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES Market Information Our common stock has traded on The Nasdaq Global Select Market under the symbol "MESA" since August 10, 2018. Prior to that date, there was no public market for our common stock. Holders of Record As of November 30, 2019, we had 23 holders of record of our common stock. Because many of our shares of common stock are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders. The transfer agent and registrar for our common stock is ComputerShare Trust Company, N.A. Dividends We have not declared or paid any cash dividends on our capital stock. We currently intend to retain any future earnings and do not expect to pay any cash dividends on our common stock for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our Board of Directors, subject to applicable laws, and will depend on our financial condition, operating results, capital requirements, general business conditions, and other factors that our Board of Directors considers relevant. Securities Authorized for Issuance Under Equity Compensation Plans The information required by this item with respect to our equity compensation plans is incorporated by reference to our definitive proxy statement for our 2020 Annual Meeting of Shareholders ("2020 Proxy Statement") to be filed with the SEC within 120 days of our fiscal year ended September 30, 2019. 31 Stock Performance Graph The following Performance Graph and related information shall not be deemed "soliciting material" or "filed" with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act or the Exchange Act, except to the extent we specifically incorporate it by reference into such filing.

SELECTED FINANCIAL DATA The following tables summarize our consolidated financial data. We derived our selected consolidated statements of operations data for our fiscal years ended September 30, 2019, 2018 and 2017 from our audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. The selected consolidated balance sheet data as of September 30, 2019 and 2018 has been derived from our audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. The selected consolidated statements of operations data for our fiscal years ended September 30, 2016 and 2015 and consolidated balance sheet data as of September 30, 2017, September 30, 2016 and September 30, 2015 have been derived from our consolidated financial statements that are not included in this Annual Report on Form 10-K. Our historical results are not necessarily indicative of the results to be expected in the future. You should read the following selected financial data in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements, including the accompanying notes included elsewhere in this Annual Report on Form 10-K.

See "Restatement" below for a discussion of restatement of weighted-average shares outstanding. (2) (3) We define Adjusted EBITDA as earnings before interest, income taxes, and depreciation and amortization, adjusted for the impact of revaluation of liability awards and lease termination costs. We define Adjusted EBITDAR as earnings before interest, income taxes, depreciation and amortization and aircraft rent, adjusted for the impact of revaluation of liability awards and lease termination costs. Adjusted EBITDA and Adjusted EBITDAR are included as supplemental disclosure 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. 33 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 profitablility. Accordingly, you are cautioned not to place undue reliance on this information. The following table sets forth a reconciliation of net income to Adjusted EBITDA and Adjusted EBITDAR for the periods presented below: Reconciliation: Net income Income tax (benefit) expense Income before taxes Adjustments(1)(2)(3) Adjusted income before taxes Interest expense Interest income Depreciation and amortization Adjusted EBITDA Aircraft rent Adjusted EBITDAR 2019 Year Ended September 30, 2018 (in thousands) 2017 $ $ $ $ 47,580 15,706 63,286 13,156 76,442 55,717 (1,501) 77,994 208,652 52,206 260,858 $ $ 33,255 (17,426) 15,829 27,165 42,994 56,867 (114) 65,031 164,778 68,892 233,670 32,828 20,874 53,702 — 53,702 46,110 (32) 61,048 160,828 72,551 233,379 (1) (2) (3) Our financial results reflect an increase in accrued compensation of approximately $13.5 million related to an increase in the value of SARs associated with an increase in fair value of our common stock as well as a change in accounting methodology from the intrinsic value method to the fair value method. These changes resulted in a general and administrative expense of approximately $11.1 million as well as an offset of approximately $2.4 million to retained earnings as a result of the change in accounting methodology for the twelve months ended September 30, 2018. Our financial results include lease termination expense of $9.5 million and $15.1 million for the twelve months ended September 30, 2019 and 2018, respectively, related to our acquisition of ten CRJ-700 and nine CRJ-900 aircraft, which were previously leased under our aircraft lease facility with Wells Fargo Bank Northwest, National Association, as owner trustee and lessor (the "GECAS Lease Facility"). Our financial results reflect loss on extinguishment of debt of $3.6 million related to repayment of the Company's Spare Engine Facility for the twelve months ended September 30, 2019. This loss includes a $1.9 million write-off of financing fees. We also had $1.0 million of financing fees written off during our twelve months ended September 30, 2018. Restatement Basic and Diluted Net Income per Common Share Available to Common Shareholders for the twelve Months Ended September 30, 2019: 34 Subsequent to the issuance of the Company's consolidated financial statements for the twelve months ended September 30, 2018, we determined our previously issued consolidated financial statements included warrants with a nominal conversion price in diluted income per common share available to common shareholders, however, they should have been included in basic income per common share available to common shareholders. As a result, basic income per common share available to common shareholders for the years ended September 30, 2018, 2017, 2016 and 2015 have been restated to appropriately include the warrants with a nominal conversion price in basic income per common share available to common shareholders. Since diluted shares are under the treasury stock method, diluted common shares available to common shareholders were impacted by this change.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements, the accompanying notes, and the other financial information included elsewhere in this Annual Report on Form 10-K. 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 those differences in our actual results include, but are not limited to, those discussed below and those discussed elsewhere in this Annual Report on Form 10-K, particularly in the sections "Cautionary Notes Regarding Forward-Looking Statements" above and Part I, Item 1A. "Risk Factors" above. Overview Mesa Airlines is a regional air carrier providing scheduled passenger service to 125 cities in 39 states, the District of Columbia, Canada, Mexico and Cuba. 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 and United. 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 September 30, 2019, we operated a fleet of 145 aircraft with approximately 730 daily departures. We operate 62 CRJ-900 aircraft under our American Capacity Purchase Agreement and 20 CRJ-700 and 60 E-175 aircraft under our United Capacity Purchase Agreement. For our fiscal year ended September 30, 2019, approximately 44% of our aircraft in scheduled service were operated for American and approximately 56% were operated for United. All of our operating revenue in our 2019, 2018 and 2017 fiscal years 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 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. 2019 Financial Highlights For our fiscal year ended September 30, 2019, we had total operating revenues of $723.4 million, a 6.1% increase, compared to $681.6 million for our fiscal year ended September 30, 2018. Net income for our fiscal year ended September 30, 2019 was $47.6 million, or $1.36 per diluted share, compared to net income of $33.3 million, or $1.32 per diluted share, for our fiscal year ended September 30, 2018. We recorded two one-time adjustments in fiscal 2019. The first was $9.5 million of non-cash lease termination expense related to our acquisition of ten CRJ-700 aircraft, which were previously leased under our aircraft lease facility with Wells Fargo Bank Northwest, National Association, as owner trustee and lessor (the "GECAS Lease Facility"). The second adjustment was $3.6 million of loss on extinguishment of debt related to repayment of the Company's Spare Engine Facility 2019. During our 2019 fiscal year, we increased our completed block hours by 45,273, or 11.0%, compared to our fiscal year ended September 30, 2018. Industry Trends We believe our operating and business performance is driven by various factors that typically affect regional airlines and their markets, including trends which affect the broader airline and travel industries, though our capacity purchase agreements reduce our exposure to fluctuations in certain trends. The following key factors may materially affect our future performance. 38 Availability and Training of Qualified Pilots. On July 8, 2013, as directed by the U.S. Congress, the FAA issued more stringent pilot qualification and crew member flight training standards, which, among other things, increased the required training time for new airline pilots from 250 hours to 1,500 hours of flight time. With these changes, the supply of qualified pilot candidates eligible for hiring by the airline industry has been dramatically reduced. To address the diminished supply of qualified pilot candidates, regional airlines implemented significant pilot wage and bonus increases. In prior periods, these factors caused our pilot attrition rates to be higher than our ability to hire and retain replacement pilots and resulted in being unable to provide flight services at or exceeding the minimum flight operating levels expected by our major airline partners. However, in July 2017, we reached a new four-year collective bargaining agreement with our pilots that provides increases in our pilots' wages, premium pay for flying on scheduled days off and competitive signing bonuses for prospective new pilots. Following the ratification of our new collective bargaining agreement, our average number of new pilot applications per month during our 2019 and 2018 fiscal year exceeded pilot attrition. Our results of operations may be negatively impacted if we are unable to hire and train our pilots in a timely manner. Pilot Attrition. In recent years, we have experienced significant volatility in our attrition as a result of pilot wage and bonus increases at other regional air carriers, the growth of cargo, low-cost and ultra low-cost carriers and the number of pilots at major airlines reaching the statutory mandatory retirement age of 65 years. If our actual pilot attrition rates are materially different than our projections, our operations and financial results could be materially and adversely affected. Economic Conditions, Challenges and Risks Market Volatility. The airline industry is volatile and affected by economic cycles and trends. Consumer confidence and discretionary spending, fear of terrorism or war, weakening economic conditions, fare initiatives, fluctuations in fuel prices, labor actions, changes in governmental regulations on taxes and fees, weather and other factors have contributed to a number of reorganizations, bankruptcies, liquidations and business combinations among major and regional airlines. The effect of economic cycles and trends may be somewhat mitigated by our reliance on capacity purchase agreements. If, however, any of our major airline partners experiences a prolonged decline in the number of passengers or is negatively affected by low ticket prices or high fuel prices, it may seek rate reductions in future capacity purchase agreements, or materially reduce our scheduled flights in order to reduce its costs. Our financial performance could be negatively impacted by any adverse changes to the rates, number of aircraft or utilization under our capacity purchase agreements. Labor. The airline industry is heavily unionized. The wages, benefits and work rules of unionized airline industry employees are determined by collective bargaining agreements. As of September 30, 2019, approximately 75.6% of our workforce was represented by the ALPA and AFA. Our pilots and flight attendants ratified new four-year collective bargaining agreements during calendar 2017. The agreements include rate increases for three years and two years, respectively, after the amendable dates. The new agreements are amendable following their four-year term and include labor rate structures for two years (flight attendants) and three years (pilots), respectively, after the amendable dates. The terms and conditions of our future collective bargaining agreements may be affected by the results of collective bargaining negotiations at other airlines that may have a greater ability, due to larger scale, greater efficiency or other factors, to bear higher costs than we can. In addition, conflicts between airlines and their unions can lead to work slowdowns or stoppages. A strike or other significant labor dispute with our unionized employees may adversely affect our ability to conduct business. Competition. The airline industry is highly competitive. We compete principally with other regional airlines. Major airlines typically award capacity purchase agreements to regional airlines based on the following criteria: ability to fly contracted schedules, availability of labor resources, including pilots, low operating cost, financial resources, geographical infrastructure, overall customer service levels relating to on-time arrival and flight completion percentages and the overall image of the regional airline. Our ability to renew our existing agreements and earn additional flying opportunities in the future will depend, in significant part, on our ability to maintain a low-cost structure competitive with other regional air carriers. Maintenance Contracts, Costs and Timing. Our employees perform routine airframe and engine maintenance along with periodic inspections of equipment at their respective maintenance facilities. We also use third-party vendors, such as AAR, Aviall, Bombardier, GE and StandardAero, for certain heavy airframe and engine maintenance work, along with parts procurement and component overhaul services for our aircraft fleet. As of September 30, 2019, $59.9 million of parts inventory was consigned to us by AAR and Aviall under long-term contracts that is not reflected on our balance sheet. 39 The average age of our E-175, CRJ-900 and CRJ-700 type aircraft is approximately 3.9, 13.0 and 15.7 years, respectively. Due to the relatively young age of our E-175 aircraft, they require less maintenance now than they will in the future. Over the past five years, we have incurred relatively low maintenance expenses on our E-175 aircraft because most of the parts are under multi-year warranties and a limited number of heavy airframe checks and engine overhauls have occurred. As our E-175 aircraft age and these warranties expire, we expect that maintenance costs will increase in absolute terms and as a percentage of revenue. In addition, because our current aircraft were acquired over a relatively short period of time, significant maintenance events scheduled for these aircraft will occur at roughly the same intervals, meaning we will incur our most expensive scheduled maintenance obligations across our present fleet at approximately the same time. These more significant maintenance activities result in out-of-service periods during which aircraft are dedicated to maintenance activities and unavailable for flying under our capacity purchase agreements. We use the direct expense method of accounting for our maintenance of regional jet engine overhauls, airframe, landing gear, and normal recurring maintenance wherein we recognize 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. While we keep a record of expected maintenance events, the actual timing and costs of major engine maintenance expense are subject to variables such as estimated usage, government regulations and the level of unscheduled maintenance events and their actual costs. Accordingly, we cannot reliably quantify the costs or timing of future maintenance-related expenses for any significant period of time. Aircraft Leasing and Finance Determinations. We have generally funded aircraft acquisitions through a combination of operating leases and debt financing. Our determination to lease or finance the acquisition of aircraft may be influenced by a variety of factors, including the preferences of our major airline partners, the strength of our balance sheet and credit profile and those of our major airline partners, the length and terms of the available lease or financing alternatives, the applicable interest rates, and any lease return conditions. When possible, we prefer to finance aircraft through debt rather than operating leases, due to lower operating costs, extended depreciation period, opportunity for aircraft equity, absence of lease return conditions and greater flexibility in renewing the aircraft under our capacity purchase agreements with our major airline partners after paying off the principal balance. Subsequent to the initial acquisition of an aircraft, we may also refinance the aircraft or convert one form of financing to another (e.g., replacing an aircraft lease with debt financing). The purchase of leased aircraft allows us to lower our operating costs and avoid lease-related use restrictions and return conditions. As of September 30, 2019, we had 60 aircraft in our fleet under lease, including 42 E-175 aircraft owned by United and leased to us at nominal amounts. In order to determine the proper classification of our leased aircraft as either operating leases or capital leases, we must make certain estimates at the inception of the lease relating to the economic useful life and the fair value of an asset as well as select an appropriate discount rate to be used in discounting future lease payments. These estimates are utilized by management in making computations as required by existing accounting standards that determine whether the lease is classified as an operating lease or a capital lease. All of our aircraft leases have been classified as operating leases, which results in rental payments being charged to expense over the terms of the related leases. We are also subject to lease return provisions that require a minimum portion of eligible flight time for certain components remain when the aircraft is returned at the lease expiration. We estimate the cost of maintenance lease return obligations and accrue such costs over the remaining lease term when the expense is probable and can be reasonably estimated. Additionally, operating leases are not reflected on our consolidated balance sheet and accordingly, neither a lease asset nor an obligation for future lease payments is reflected in our consolidated balance sheets. See "Recent Accounting Pronouncements" in the notes to our consolidated financial statements below for a discussion of a new accounting standard that is likely to have an impact on our aircraft lease accounting beginning in our 2020 fiscal year. See "Risk Factors" for a discussion of these factors and other risks. Seasonality Our results of operations for any interim period are not necessarily indicative of those for the entire year, since the airline industry is subject to seasonal fluctuations and general economic conditions. Our operations are somewhat favorably affected by increased utilization of our aircraft in the summer months and are unfavorably affected by increased fleet maintenance and by inclement weather during the winter months. 40 Components of Our Results of Operations The following discussion summarizes the key components of our consolidated statements of operations. Operating Revenues Our 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, landing fees, catering and certain maintenance costs related to our E-175 aircraft. Operating Expenses Our operating expenses consist of the following items: 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 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. As a result of using the direct expense method, the timing of maintenance expense reflected in the financial statements may vary significantly from 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, non-operational administrative employee wages and related expenses, building rents, real property leases, utilities, legal, audit and other administrative expenses. The majority of insurance and taxes are pass-through costs. 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. Other (Expense) Income, Net 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. 41 Other Expense. Other expense includes expense derived from activities not classified in any other area of the consolidated statements of income, including write-offs of miscellaneous third-party fees. Segment Reporting 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 Accounting Standards Codification ("ASC") 280, "Segment Reporting," we are not organized around specific services or geographic regions. We currently operate in one service line providing scheduled flying 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 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. He 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. Results of Operations Comparison of our Fiscal Years Ended September 30, 2019 and 2018 We had operating income of $121.1 million in our fiscal year ended September 30, 2019, compared to operating income of $72.6 million in September 30, 2018. In our 2019 fiscal year, we had net income of $47.6 million compared to net income of $33.3 million in our 2018 fiscal year. Our operating results for our fiscal year ended September 30, 2019 reflected an increase in contract revenue primarily related to the additional flying of our E-175, CRJ-900 and CRJ-700 fleets as a result of increased pilot staffing level. We also experienced a decrease in aircraft rent expense as a result of purchasing nine CRJ-900 aircraft in June 2018 and ten CRJ-700 aircraft in June 2019 that were previously leased under our GECAS Lease Facility. We also experienced a decrease in lease termination expense for ten CRJ-700 aircraft purchased in June 2019, compared to the lease termination expense associated with the purchase of nine CRJ-900 aircraft in June 2018, both previously leased under our GECAS Lease Facility.

Contract revenue increased by $43.6 million, or 6.8%, primarily due to an increase in flying with our E-175, CRJ-900 and CRJ-700 fleets, an increase in performance incentive pay, and a decrease in credits given to our major airline partners based on contractual utilization levels. Our block hours flown during our fiscal year September 30, 2019 increased 11.0%, compared to our fiscal year ended September 30, 2018, due to increased flying with our E-175, CRJ-900 and CRJ-700 fleets. Our pass-through and other revenue decreased during our fiscal year ended September 30, 2019 by $1.8 million, or 4.3%, primarily due to a reduction in pass-through maintenance costs related to our E-175 fleet.

Flight operations expense increased $1.8 million, or $0.9%, to $210.9 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. The increase was primarily driven by an increase in pilot and flight attendant wages due to additional flying, offset by a decrease in pilot premium pay as our pilot staffing levels have improved. Fuel. Fuel expense increased $0.09 million, or 18.1%, to $0.6 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. The increase was primarily driven by an increased number of ferry flights for maintenance events and maintenance fuel in our Phoenix hub. All fuel costs related to flying under our capacity purchase agreements during our fiscal years ended September 30, 2019 and 2018 were directly paid to suppliers by our major airline partners. Maintenance. Aircraft maintenance costs increased $3.4 million, or 1.7%, to $196.5 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. This increase was primarily driven by an increase in labor and other expense, component contracts, and rotable and expendable parts expense. This increase was partially offset by a decrease in engine and pass-through engine and C-Check expense. During our 2019 fiscal year, $6.0 million of engine overhaul expenses were reimbursable by our major airline partners. Total pass-through maintenance expenses reimbursed by our major airline partners decreased by $8.6 million during our fiscal 2019, compared to fiscal 2018. 43 The following table presents information regarding our aircraft maintenance costs during our fiscal years ended September 30, 2019 and 2018: Engine overhaul Pass-through engine overhaul C-check Pass-through C-check Component contracts Rotable and expendable parts Other pass-through Labor and other Total Year Ended September 30, 2019 2018 (in thousands) Change 24,077 $ 5,960 $ 16,807 $ 396 $ 37,572 $ 29,853 $ 12,885 $ $ 68,964 $ 196,514 38,869 $ (14,792) $ (6,381) 12,341 $ 2,759 14,048 $ (7,060) 7,456 $ 4,351 33,221 $ 5,864 23,989 $ 4,866 8,019 $ 13,743 $ 55,221 3,350 $ 193,164 $ (38.1)% (51.7)% 19.6% (94.7)% 13.1% 24.4% 60.7% 24.9% 1.7% Aircraft Rent. Aircraft rent expense decreased $16.7 million, or 24.2%, to $52.2 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. This decrease was primarily attributable to $16.6 million decrease in aircraft lease expense due to the purchase of nine CRJ-900 and ten CRJ-700 aircraft, previously leased under the GECAS Lease Facility, in June 2018 and June 2019, respectively. Aircraft and Traffic Servicing. Aircraft and traffic servicing expense increased $0.4 million, or 12.2%, to $4.0 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. This increase was primarily due to an increase in interrupted trip expense and higher pass-through regulatory charges. For our fiscal years ended September 30, 2019 and 2018, 52.6% and 53.0%, respectively, of our aircraft and traffic servicing expenses were reimbursed by our major airline partners. General and Administrative. General and administrative expense decrease $3.1 million, or 5.8%, to $50.5 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. This decrease was primarily due to a decrease in amortization of our restricted stock compensation and slightly offset in pass- through property tax and passenger liability expense. Depreciation and Amortization. Depreciation and amortization expense increased $13.0 million, or 19.9%, to $78.0 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. This increase was primarily attributable to an increase in depreciation expense related to our purchase of spare engines and aircraft depreciation related to the purchase of the nine CRJ-900 and ten CRJ-700 aircraft, previously leased under the GECAS Lease Facility, in June 2018 and June 2019 respectively. Lease Termination. Lease termination expense decreased $5.6 million, or 36.9%, for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. The decrease is primarily driven by a lower lease termination expense for the ten CRJ-700 aircraft purchased in June 2019, compared to the lease termination expense associated the purchase of the nine CRJ-900 aircraft in June 2018, which were both under the GECAS Lease facility. Other Expense Other expense increased $1.0 million, or 1.8%, to $57.9 million for our fiscal year ended September 30, 2019, compared to our fiscal year ended September 30, 2018. The increase is primarily due to a one-time extinguishment of debt expense of $3.6 million related to the repayment of our Spare Engine Facility. Interest expense decreased $1.2 million primarily due to a decrease in interest expense related to our Spare Engine Facility, CIT Revolving Credit Facility and EDC engine financing, which decrease was partially offset by an increase in interest expense due to the financing of nine CRJ-900 and ten CRJ-700 aircraft in June 2018 and June 2019, respectively, which were previously leased under the GECAS Lease Facility. Our expenses related to debt financing amortization decreased by $0.3 million is primarily due to the write-off of financing fees related to the repayment of our Spare Engine Facility. Additionally, interest income increased by $1.4 million in the twelve months ended September 30, 2019, compared to the same period in 2018. 44 Income Taxes In our fiscal year ended September 30, 2019, our effective tax rate was 24.8% compared to (110.1%) in our fiscal year ended September 30, 2018. Our tax rate can vary depending on changes in tax laws, adoption of accounting standards, the amount of income we earn in each state and the state tax rate applicable to such income, as well as any valuation allowance required on our state net operating losses. We recorded an income tax provision of $15.7 million and an income tax provision of ($17.4) million for the years ended September 30, 2019 and 2018, respectively. The income tax provision for our fiscal year ended September 30, 2019 resulted in an effective tax rate of 25.0%, which differed from the U.S. federal statutory rate of 21%, primarily due to the impact of state taxes and permanent differences between financial statement and taxable income. In addition to the state effective tax rate impact, other state impacts include changes in the valuation allowance against state net operating losses, expired state attributes, and changes in state apportionment and statutory rates. The income tax provision for our fiscal year ended September 30, 2018 resulted in an effective tax rate of (110.1%), which differed from the U.S. federal statutory rate of 35% through December 31, 2017 and 21% as of January 1, 2018, primarily due to a re-measurement of our net deferred tax liability due to federal tax law changes and the adoption of Accounting Standards Update 2016-09. Other factors include changes in the valuation allowance against state net operating losses, expired state attributes and state apportionment and statutory rates. On December 22, 2017, the President signed the Tax Act into law. The Tax Act incorporated several new provisions that had an impact on our financial statements. Most notably, the Tax Act decreased the federal statutory rate to 21% for our fiscal year ended September 30, 2019 and subsequent fiscal years. The decrease in the federal statutory rate resulted in a net tax benefit in fiscal 2018 due to the re-measurement of our net deferred tax liability. The Company's net operating losses incurred in the fiscal year ended September 30, 2019 and in subsequent years may be used to offset up to 80% of taxable income in a given year and the Company’s net operating losses incurred in fiscal year ended September 30, 2018 and in subsequent fiscal years are allowed to be carried indefinitely. 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, we had aggregate federal and state net operating loss carryforwards of approximately $478.3 million and $228.3 million, which expire in 2027-2037 and 2020-2039, respectively, with approximately $0.9 million of state net operating loss carryforwards that expired in 2019. See Note 12: "Income Taxes" in the notes to the audited consolidated financial statements included elsewhere in this Annual Report Form 10-K. Comparison of our Fiscal Years Ended September 30, 2018 and 2017 We had operating income of $72.6 million in our fiscal year ended September 30, 2018, compared to operating income of $100.3 million in our fiscal year ended September 30, 2017. In our 2018 fiscal year, we had net income of $33.3 million compared to net income of $32.8 million in our 2017 fiscal year. Our operating results for our fiscal year ended September 30, 2018 reflected an increase in contract revenue primarily related to the addition of 12 E-175 aircraft under our United Capacity Purchase Agreement, which was partially offset by reduced flying of our CRJ-900 and CRJ-700 fleet. We also experienced an increase in flight operations expense driven by an increase in pilot training and related expenses and an increase in premium pilot pay to incentivize pilots to fly additional routes until additional pilots complete their training. Our maintenance expense decreased due to the timing of significant engine overhaul events, which occurred less frequently during our fiscal year ended September 30, 2018 than during our fiscal year ended September 30, 2017. We recorded two one-time non-cash adjustments in our fiscal year ended September 30, 2018. The first adjustment was $15.1 million of lease termination expense related to our acquisition of nine CRJ-900 aircraft, which were previously leased under our GECAS Lease Facility. The second adjustment related to an increase in the value of our SARs associated with an increase in fair value of our common stock as well as a change in accounting methodology from the intrinsic value method to fair value method. These changes resulted in a general and administrative expense of $11.1 million. 45 Operating Revenues Operating revenues ($ in thousands): Contract Pass-through and other Total operating revenues Operating data: (1) Available seat miles—ASMs (miles in thousands) Block hours Revenue passenger miles—RPMs (miles in thousands) Average stage length (miles) Contract revenue per available seat mile— CRASM (in cents) Passengers Year Ended September 30, 2018 2017 Change $ $ $ 639,264 $ 42,331 $ 681,595 $ 618,698 $ 24,878 643,576 $ 20,566 17,453 38,019 3.3% 70.2% 5.9% 9,713,877 9,471,911 241,966 15,891 410,974 395,083 7,699,065 7,392,688 306,377 (1) 560 561 ¢ 0.05 13,556,774 13,005,844 550,930 6.53 ¢ 6.58 ¢ 2.6% 4.0% 4.1% (0.2)% 0.8% 4.2% (1) The definitions of certain terms related to the airline industry used in the table can be found under "Glossary of Airline Terms' in Part II, Item 6 "Selected Financial Data" above. Total operating revenue increased by $38.0 million, or 5.9%, during our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. Contract revenue increased by $20.6 million, or 3.3%, primarily due to an increase in flying with our expanded E-175 fleet and higher block hour compensation. Our block hours flown during our fiscal year ended September 30, 2018 increased 4.0%, compared to our fiscal year ended September 30, 2017, due to increased flying on our E-175 fleet, which was partially offset by reduced flight schedules caused by increased pilot training times. Our pass-through and other revenue increased during our fiscal year ended September 30, 2018 by $17.5 million, or 70.2%, primarily due to pass-through maintenance costs related to our E-175 fleet Operating Expenses Operating expenses ($ in thousands): Flight operations Fuel Maintenance Aircraft rent Aircraft and traffic servicing General and administrative Depreciation and amortization Lease Termination Total operating expenses Operating data: Available seat miles—ASMs (miles in thousands) Block hours Average stage length (miles) Departures Year Ended September 30, 2018 2017 Change 498 $ $ 209,065 $ 155,516 $ 53,549 (268) 766 $ $ $ 193,164 $ 210,729 $ (17,565) 72,551 $ (3,659) $ 3,676 $ $ (135) 38,996 $ 14,651 $ 3,983 61,048 $ $ — $ 15,109 $ 65,665 $ 608,947 $ 543,282 $ 68,892 $ 3,541 $ 53,647 $ 65,031 $ 15,109 $ 9,713,877 9,471,911 241,966 15,891 (1) 5,988 410,974 560 227,978 395,083 561 221,990 34.4% (35.0)% (8.3)% (5.0)% (3.7)% 37.6% 6.5% 100.0% 12.1% 2.6% 4.0% (0.2)% 2.7% Flight Operations. Flight operations expense increased $53.5 million, or 34.4%, to $209.1 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This increase was primarily driven by an increase in pilot training related expenses, an increase in premium pilot pay to incentivize pilots to fly additional routes until additional pilots complete their training and additional pilot and flight attendant wages due to the additional flying, as well as our new collective bargaining agreements. 46 Fuel. Fuel expense decreased $0.3 million, or 35.0%, to $0.5 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. The decrease was primarily driven by a reduced number of ferry flights for maintenance events and maintenance fuel in our Phoenix hub. All fuel costs related to flying under our capacity purchase agreements during our fiscal years ended September 30, 2018 and 2017 were directly paid to suppliers by our major airline partners. Maintenance. Aircraft maintenance costs decreased $17.6 million, or 8.3%, to $193.2 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This decrease was primarily driven by a decrease in engine overhaul expense, rotable and expendable parts expense and labor and other expense. This decrease was partially offset by an increase in component contracts expense and other pass-through expense. During our 2018 fiscal year, $12.3 million of engine overhaul expenses were reimbursable by our major airline partners. Total pass- through maintenance expenses reimbursed by our major airline partners increased by $16.7 million during our fiscal 2018, compared to fiscal 2017. The following table presents information regarding our aircraft maintenance costs during our fiscal years ended September 30, 2018 and 2017: Year Ended September 30, 2018 2017 (in thousands) Change Engine overhaul Pass-through engine overhaul C-check Pass-through C-check Component contracts Rotable and expendable parts Other pass-through Labor and other Total $ 38,869 $ 12,341 14,048 7,456 33,221 23,989 8,019 55,221 63,719 $ (24,850) 12,071 (3,707) 2,567 1,550 (2,109) 2,016 (5,103) $ 193,164 $ 210,729 $ (17,565) 270 $ 17,755 $ 4,889 $ 31,671 $ 26,098 $ 6,003 $ 60,324 (39.0)% 4470.7% (20.9)% 52.5% 4.9% (8.1)% 33.6% (8.5)% (8.3)% Aircraft Rent. Aircraft rent expense decreased $3.7 million, or 5.0%, to $68.9 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This decrease was attributable to a $0.3 million increase in engine rent and a $3.9 million decrease in aircraft lease expense due to purchasing nine CRJ-900 aircraft, previously leased under the GECAS Lease Facility, in June 2018. Aircraft and Traffic Servicing. Aircraft and traffic servicing expense decreased $0.1 million, or 3.7%, to $3.5 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This decrease was primarily due to a decrease in interrupted trip expense which was partially offset by higher pass-through regulatory charges. For our fiscal years ended September 30, 2018 and 2017, 53.0% and 46.5%, respectively, of our aircraft and traffic servicing expenses were reimbursed by our major airline partners. General and Administrative. General and administrative expense increased $14.7 million, or 37.6%, to $53.6 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This increase was primarily related to a one-time, non-cash $11.1 million expense related to an increase in the value of our SARs associated with an increase in fair value of our common stock as well as a change in accounting methodology from the intrinsic value method to fair value method. The remainder of the variance was due to an increase in audit fees, property taxes and fees associated with restructuring the RASPRO Lease Facility. Depreciation and Amortization. Depreciation and amortization expense increased $4.0 million, or 6.5%, to $65.0 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This increase was primarily attributable to an increase in depreciation expense related to our purchase of spare engines and aircraft depreciation related to the purchase of the nine CRJ-900 aircraft, previously leased under the GECAS Lease Facility, in June 2018. Lease Termination. Lease termination expense increased $15.1 million, or 100%, for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This increase was related to our acquisition of nine CRJ- 900 aircraft, previously leased under the GECAS Lease Facility, in June 2018. 47 Other Expense Other expense increased $10.2 million, or 22.0%, to $56.8 million for our fiscal year ended September 30, 2018, compared to our fiscal year ended September 30, 2017. This increase was primarily due to an increase in interest expense of $8.7 million related to the financing of 23 spare engines, the financing of nine CRJ-900 aircraft, previously leased under our GECAS Lease Facility, in June 2018, the refinancing of fifteen CRJ-900 aircraft, our line of credit with CIT, a deferment of certain payments under the RASPRO Lease Facility, engine overhaul financing and higher London InterBank Offered Rate ("LIBOR") rates. Our expenses related to debt financing amortization were also higher in our fiscal 2018 by $1.9 million, which was attributable to legal and commitment fees incurred in connection with our aircraft and engine financing, as well as aircraft debt refinancing Income Taxes In our fiscal year ended September 30, 2018, our effective tax rate was (110.1%) compared to 38.9% in our fiscal year ended September 30, 2017. Our tax rate can vary depending on changes in tax laws, adoption of accounting standards, the amount of income we earn in each state and the state tax rate applicable to such income, as well as any valuation allowance required on our state net operating losses. We recorded an income tax provision of ($17.4) million and an income tax provision of $20.9 million for the years ended September 30, 2018 and 2017, respectively. The income tax provision for the year ended September 30, 2018 results in an effective tax rate of (110.1%), which differed from the U.S. federal statutory rate of 35% through December 31, 2017 and 21% as of January 1, 2018 primarily due to a re-measurement of our net deferred tax liability due to federal tax law changes and the adoption of Accounting Standards Update (ASU) 2016-09. Other factors include changes in the valuation allowance against state net operating losses, expired state attributes and state apportionment and statutory rates. The income tax provision for the year ended September 30, 2017 results in an effective tax rate of 38.9%, which differed from the U.S. federal statutory rate of 35% primarily due to state taxes, changes in the valuation allowance against state net operating losses, expired state attributes, and the benefit resulting from changes in state apportionment and statutory rates. On December 22, 2017, the President signed into law the legislation colloquially known as the Tax Cuts and Jobs Act (the "Tax Act"). The Tax Act incorporates several new provisions that will have an impact on our financial statements. Most notably, the Tax Act decreased the federal statutory rate to 24.5% for the year ending September 30, 2018, and 21% for the years ending September 30, 2019 and forward. The decrease in federal statutory rate resulted in a net tax benefit due to the re-measurement of our net deferred tax liability. The change in our future effective tax rate is not anticipated to have an effect on our taxes until all of our U.S. federal net operating losses and credits have been utilized. Additional provisions of the Tax Act that may impact our financial statements include 100% expensing of qualified property placed in service after September 27, 2017 and before January 1, 2023, refundable minimum tax credits over a four year period, net interest expense deductions limited to 30% of earnings before interest, taxes, depreciation, and amortization through 2021 and of earnings before interest and taxes thereafter, and net operating losses incurred in tax years beginning after December 31, 2017 are only allowed to offset up to 80% of a taxpayer’s taxable income. These net operating losses are allowed to be carried forward indefinitely. 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, 2018, we had aggregate federal and state net operating loss carryforwards of approximately $415.1 million and $199.5 million, which expire in 2027-2037 and 2019-2038, respectively, with approximately $20.1 million of state net operating loss carryforwards that expired in 2018. See Note 11: "Income Taxes" in the notes to the audited consolidated financial statements included elsewhere in this Annual Report of Form 10-K. 48 Cautionary Statement Regarding Non-GAAP Measures We present Adjusted EBITDA and Adjusted EBITDAR in this Annual Report on Form 10-K, which are not recognized financial measures under accounting principles generally accepted in the United States of America ("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, 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. You are encouraged to evaluate these adjustments and the reasons we consider them appropriate for supplemental analysis. In evaluating Adjusted EBITDA and Adjusted EBITDAR, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in our presentation of Adjusted EBITDA and Adjusted EBITDAR. Our presentation of Adjusted EBITDA and Adjusted EBITDAR should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. There can be no assurance that we will not modify the presentation of Adjusted EBITDA or Adjusted EBITDAR and any such modification may be material. 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. 49 Adjusted EBITDA and Adjusted EBITDAR The following table presents a reconciliation of net (loss) income to estimated Adjusted EBITDA and Adjusted EBITDAR for the period presented: Reconciliation: Net income Income tax (benefit) expense Income before taxes Adjustments(1)(2)(3) Adjusted income before taxes Interest expense Interest income Depreciation and amortization Adjusted EBITDA Aircraft rent Adjusted EBITDAR 2019 Year Ended September 30, 2018 (in thousands) 2017 $ $ $ $ 47,580 15,706 63,286 13,156 76,442 55,717 (1,501) 77,994 208,652 52,206 260,858 $ $ 33,255 (17,426) 15,829 27,165 42,994 56,867 (114) 65,031 164,778 68,892 233,670 32,828 20,874 53,702 — 53,702 46,110 (32) 61,048 160,828 72,551 233,379 (1) (2) (3) Our financial results reflect an increase in accrued compensation of approximately $13.5 million related to an increase in the value of SARs associated with an increase in fair value of our common stock as well as a change in accounting methodology from the intrinsic value method to the fair value method. These changes resulted in a general and administrative expense of approximately $11.1 million as well as an offset of approximately $2.4 million to retained earnings as a result of the change in accounting methodology for the twelve months ended September 30, 2018. Our financial results include lease termination expense of $9.5 million and $15.1 million for the twelve months ended September 30, 2019 and 2018, respectively, related to our acquisition of ten CRJ-700 and nine CRJ-900 aircraft, which were previously leased under our GECAS Lease Facility. Our financial results reflect loss on extinguishment of debt of $3.6 million related to repayment of the Company's Spare Engine Facility for the twelve months ended September 30, 2019. This loss includes a $1.9 million write-off of financing fees. We also had $1.0 million of financing fees written off during our twelve months ended September 30, 2018. Liquidity and Capital Resources Sources and Uses of Cash 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 the CIT Revolving Credit Facility, pursuant to which the lenders named therein (the "CIT Lenders") have committed to lend to Mesa Airlines and MAG-AIM revolving loans in the aggregate principal amount of up to $35.0 million. This facility was paid down with proceeds from our IPO on August 14, 2018 but remains available 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: (cid:3) (cid:3) Factors that affect our results of operations and cash flows, including the impact on our business and operations as a result of changes in demand for our services, competitive pricing pressures, and our ability to achieve further reductions in operating expenses; and Factors that affect our access to bank financing and the debt and equity capital markets that could impair our ability to obtain needed financing on acceptable terms or to respond to business opportunities and developments as they arise, including interest rate fluctuations, macroeconomic conditions, sudden reductions in the general availability of lending from banks or the related increase in cost to obtain bank financing, and our ability to maintain compliance with covenants under our debt agreements in effect from time to time. 50 Our ability to service our long-term debt obligations, including our equipment notes, to remain in compliance with the various covenants contained in our debt agreements and to fund working capital, capital expenditures and business development efforts will depend on our ability to generate cash from operating activities, which is subject to, among other things, our future operating performance, as well as 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 and existing credit facilities 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. Prior to our IPO, our operations had been financed primarily by cash flow from operating activities and funds from external borrowings. As of September 30, 2019, we had $68.9 million in cash and cash equivalents and marketable securities. In connection with our IPO, we issued and sold an aggregate of 9,630,000 shares of common stock as well as 723,985 shares of common stock from the exercise of the over-allotment option granted to the underwriters, which was exercised on September 11, 2018 at a price to the public of $12.00 per share. We received proceeds of $111.7 million, net of underwriting discounts and commissions and offering costs. 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. During our fiscal year ended September 30, 2019, we paid $125.4 million in capital expenditures primarily related to the purchase of ten CRJ-700 aircraft, which were previously leased, and eight spare engines. Our capital expenditures, net of purchases of rotable spare parts and aircraft and spare engine financing, have historically been approximately 1.5% to 2.5% of annual revenues, and 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 September 30, 2019, our principal sources of liquidity were cash and cash equivalents and marketable securities of $68.9 million. In addition, we had restricted cash of $3.6 million as of September 30, 2019. Restricted cash includes certificates of deposit that secure letters of credit issued for particular airport authorities as required in certain lease agreements. Furthermore, as of September 30, 2019, we also had $750.5 million in secured indebtedness incurred in connection with our financing of 84 total aircraft. Our primary uses of liquidity are capital expenditures and debt repayments. As of September 30, 2019, we had $165.9 million of short-term debt, excluding capital leases, and $677.4 million of long-term debt excluding capital leases. Sources of cash for our fiscal year ended September 30, 2019 were primarily cash flows from operations of $151.7 million. The positive cash flow from operations was driven by receipts from performance under our capacity purchase agreements.

Actual interest commitments will change based on the actual variable interest. Operating Leases We have significant long-term lease obligations primarily relating to our aircraft fleet. The leases are classified as operating leases and are therefore excluded from our consolidated balance sheets. As of September 30, 2019, we had 18 aircraft on lease (excluding aircraft leased from United) with remaining lease terms up to 4.5 years. Future minimum lease payments due under all long-term operating leases were approximately $155.4 million as of September 30, 2019. RASPRO Lease Facility. On September 23, 2005, Mesa Airlines, as lessee, entered into the RASPRO Lease Facility, with RASPRO as lessor, for 15 of our CRJ-900 aircraft. The obligations under the RASPRO Lease Facility are guaranteed by us, and basic rent is paid quarterly on each aircraft. On each of March 10, 2014, June 5, 2014 and December 8, 2017, the RASPRO Lease Facility was amended to defer certain payments of basic rent (the "Deferred Amounts"). Until the principal of and accrued interest on the Deferred Amounts are paid in full, (i) we and Mesa Airlines are prohibited from paying any dividends to holders of our common stock, (ii) we are prohibited from repurchasing any of our warrants or other equity interests, (iii) Mesa Airlines must maintain available a minimum of $10 million of cash, cash equivalents and availability under lines of credit, (iv) Mesa Airlines must provide RASPRO with periodic monthly, quarterly and annual reports containing certain financial information and forecasted engine repair costs and (v) we must maintain a minimum debt-to-assets ratio. 53 Pursuant to the December 2017 amendment referenced above, we deferred $29.3 million of payments originally due in December 2017 through March 2018. Deferred Amounts are charged 7.5% interest per annum and are due for repayment in December 2021. As of September 30, 2019, we were in compliance with the covenants in the RASPRO Lease Facility. GECAS Lease Facility. On May 27, 2014, Mesa Airlines, as lessee, entered into an aircraft lease facility with Wells Fargo Bank Northwest, National Association, as owner trustee and lessor, governing the lease of 19 of our CRJ-700 and CRJ- 900 aircraft. The obligations under the GECAS Lease Facility are guaranteed by us, and basic rent is paid monthly on each aircraft. In consideration for the lease, we issued a warrant to purchase 250,000 shares of our common stock to GE Capital Aviation Services LLC (the "GE Warrant"), which we mutually agreed to terminate in connection with our purchase of nine CRJ-900 aircraft in June 2018 that we previously leased under the GECAS Lease Facility. The GECAS Lease Facility requires Mesa Airlines and us to maintain a balance of unrestricted cash of not less than $10 million and prohibited us from paying dividends to holders of our common stock prior to September 30, 2019 without the prior written consent of the GECAS Lease Facility parties. As of September 30, 2019, all the aircraft under the GECAS Lease Facility have been purchased, therefore, the covenants are no longer in effect. As more fully described under "Aircraft Notes" below, on June 26, 2018, we purchased nine CRJ-900 aircraft, which were previously leased under the GECAS Lease Facility, for $76.5 million and terminated the GE Warrant.

Capital Leases On February 7, 2018, Mesa Airlines, as lessee, entered into two agreements for the lease of two spare aircraft engines (the "Engine Leases"). Basic rent on the engines is paid monthly and at the end of the lease term. In November 2022, Mesa Airlines will have the option to purchase the engines for $935,230. The Engine Leases are reflected as debt obligations of $8.5 million on our balance sheet as of September 30, 2019. The Engine Leases set forth specific redelivery requirements and conditions, but do not contain operational or financial covenants. Working Capital Line of Credit In August 2016, we, as guarantor, our wholly owned subsidiaries, Mesa Airlines and MAG-AIM, as borrowers, CIT, as administrative agent, and the lenders party thereto, entered into the CIT Revolving Credit Facility, pursuant to which the CIT Lenders committed to lend to Mesa Airlines and MAG-AIM revolving loans in the aggregate principal amount of up to $35.0 million. The borrowers' and guarantor's obligations under the CIT Revolving Credit Facility are secured primarily by a first priority lien on certain engines, spare parts and related collateral, including engine warranties and proceeds of the foregoing. The CIT Revolving Credit Facility contains affirmative, negative and financial covenants that are typical in the industry for similar financings, including, but not limited to, covenants that, subject to exceptions described in the CIT Revolving Credit Facility, restrict our ability and the ability of Mesa Airlines and MAG-AIM and their subsidiaries to: (i) enter into, create, incur, assume or suffer to exist any liens; (ii) merge, dissolve, liquidate, consolidate or sell or transfer substantially all of its assets; (iii) sell assets; (iv) enter into transactions with affiliates; (v) amend certain material agreements and organizational documents; (vi) make consolidated unfinanced capital expenditures; or (viii) maintain a consolidated interest and rental coverage ratio above the amount specified in the CIT Revolving Credit Facility.

In February 2018, the parties amended the Spare Engine Facility to increase the commitment of the Engine Financing Lenders by an additional aggregate principal amount of up to approximately $4.1 million. Mesa Airlines' obligations under the Spare Engine Facility are secured primarily by a first priority lien on certain engines acquired with the proceeds of the Spare Engine Facility and related collateral, including engine warranties and proceeds of the foregoing.

This interest rate is significantly lower than the interest rate under the Company's Spare Engine Facility (LIBOR plus 7.25%), which the Term Loan refinanced and replaced. 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.

Our employees perform routine airframe and engine maintenance along with periodic inspections of equipment at their respective maintenance facilities. We also use third-party vendors, such as AAR, Aviall and GE, for certain heavy airframe and engine maintenance work, along with parts procurement and component overhaul services for our aircraft fleet. As of September 30, 2019, $59.9 million of parts inventory was consigned to us by AAR and Aviall under long-term contracts that is not reflected on our balance sheet. We use the direct expense method of accounting for our maintenance of regional jet engine overhauls, airframe, landing gear, and normal recurring maintenance wherein we recognize 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. While we keep a record of expected maintenance events, the actual timing and costs of major engine maintenance expense are subject to variables such as estimated usage, government regulations and the level of unscheduled maintenance events and their actual costs. Accordingly, we cannot reliably quantify the costs or timing of future maintenance-related expenses for any significant period of time. Off-Balance Sheet Arrangements 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 have no off-balance sheet arrangements of the types described in the four categories above that we believe may have material current or future effect on financial condition, liquidity or results of operations. 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. Critical Accounting Policies We prepare our 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. We have identified the accounting policies discussed below as critical to us. The discussion below is not intended to be a comprehensive list of our accounting policies. Our significant accounting policies are more fully described in Note 2: "Summary of Significant Accounting Policies" to the consolidated financial statements. Adoption of New Revenue Standard On October 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09" or "ASC 606") using the modified retrospective method. See Note 3: "Recent Accounting Pronouncements" in the notes to our consolidated financial statements for more information. To conform to ASC 606, the Company modified its revenue recognition policy as described below. 58 Revenue Recognition The Company recognizes revenue when the service is provided under its capacity purchase agreements. Under these agreements, the major airline partners generally pay a fixed monthly minimum amount per aircraft, plus certain additional amounts based upon the number of flights and block hours flown. The contracts also include reimbursement of certain costs incurred by the Company in performing flight services. These costs, known as "pass-through costs," may include passenger and hull insurance as well as aircraft property taxes. Additionally, for the E-175 aircraft owned by United, the capacity purchase agreement provides that United will reimburse the Company for heavy airframe and engine maintenance, landing gear, APUs and component maintenance. The Company also receives compensation under its capacity purchase agreements for heavy maintenance expenses at a fixed hourly rate or per aircraft rate for all aircraft in scheduled service other than the E-175 aircraft owned by United. The contracts also include a profit margin on certain reimbursable costs, as well as a profit margin, incentives and penalties based on certain operational benchmarks. The Company is eligible to receive incentive compensation upon the achievement of certain performance criteria defined in the capacity purchase agreements. At the end of each period during the term of an agreement, the Company calculates the incentives achieved during that period and recognizes revenue attributable to the agreement during the period accordingly, subject to the variable constraint guidance under ASC 606. All revenue recognized under these contracts is presented as the gross amount billed to the major airline partners. Under the capacity purchase agreements, the Company has committed to perform various activities that can be generally classified into in-flight services and maintenance services. When evaluating these services, the Company determined that the nature of its promise is to provide a single integrated service, flight services, because its contracts require integration and assumption of risk associated with both services to effectively deliver and provide the flights as scheduled over the contract term. Therefore, the in-flight services and maintenance services are inputs to that combined integrated flight service. Both the services occur over the term of the agreement and the performance of maintenance services significantly effects the utility of the in-flight services. The Company's individual flights flown under the capacity purchase agreements are deemed to be distinct and the flight service promised in the capacity purchase agreements represents a series of services that should be accounted for as a single performance obligation. This single performance obligation is satisfied over time as the flights are completed. Therefore, revenue is recognized when each flight is completed. In allocating the transaction price, variable payments (i.e. billings based on flights and block hours flown, pass-through costs, etc.) that relate specifically to the Company's efforts in performing flight services are recognized in the period in which the individual flight is completed. The Company has concluded that allocating the variability directly to the individual flights results in an overall allocation meeting the objectives in ASC 606. This results in a pattern of revenue recognition that follows the variable amounts billed from the Company to their customers. 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 $219.0 million, $217.0 million and 217.6 million of lease revenue for the twelve months ended September 30, 2019, 2018 and 2017, 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. The Company's capacity purchase agreements are renewable periodically and contain provisions pursuant to which the parties could terminate their respective agreements, subject to certain conditions as described in Note 1. The capacity purchase agreements also contain terms with respect to covered aircraft, services provided and compensation as described in Note 1. The capacity purchase agreements are amended from time to time to change, add or delete terms of the agreements. The Company's revenues could be impacted by a number of factors, including amendment or termination of its capacity purchase agreements, contract modifications resulting from contract renegotiations, its ability to earn incentive payments contemplated under applicable agreements, and settlement of reimbursement disputes with the Company's major airline partners. In the event contracted rates are not finalized at a quarterly or annual financial statement date, the Company evaluates the enforceability of its contractual terms and when it has an enforceable right, it estimates the amount the Company expects to be entitled to that is subject to the ASC 606 constraint. 59 The Company's capacity purchase agreements contain an option that allows its major airline partners to assume the contractual responsibility for procuring and providing the fuel necessary to operate the flights that it operates for them. Both of the Company's major airline partners have exercised this option. Accordingly, the Company does not record an expense or revenue for fuel and related fueling costs for flying under its capacity purchase agreements. In addition, the Company's major airline partners also provide, at no cost to the Company, certain ground handling and customer service functions, as well as airport-related facilities and gates at their hubs and other cities. Services and facilities provided by the Company's major airline partners at no cost are presented net in its condensed consolidated financial statements; hence, no amounts are recorded for revenue or expense for these items. Maintenance Expense We operate under an FAA-approved continuous inspection and maintenance program. We use the direct expense method of accounting for our maintenance of regional jet engine overhauls, airframe, landing gear, and normal recurring maintenance wherein we recognize 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, we are 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. We estimate the cost of maintenance lease return obligations and accrue such costs over the remaining lease term when the expense is probable and can be reasonably estimated. Under our aircraft operating lease agreements and FAA operating regulations, we are obligated to perform all required maintenance activities on our fleet, including component repairs, scheduled air frame checks and major engine restoration events. We estimate 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 our aircraft, changes in government regulations and suggested manufacturer maintenance intervals. Major maintenance events consist of overhauls to major components. Engine overhaul expense totaled $30.0 million, $51.2 million and $64.0 million for our fiscal years ended September 30, 2019, 2018 and 2017, respectively, of which $6.0 million, $12.3 million and $0.3, respectively, was pass-through expense. Airframe C-check expense totaled $17.2 million, $21.5 million and $22.6 million for our fiscal years ended September 30, 2019, 2018, and 2017, respectively, of which $0.4 million, $7.5 million and $4.9, respectively, was pass-through expense. Aircraft Leases In addition to the aircraft we receive from United under our Capacity Purchase Agreement, approximately 19% of our aircraft are leased from third parties. In order to determine the proper classification of a lease as either an operating lease or a capital lease, we must make certain estimates at the inception of the lease relating to the economic useful life and the fair value of an asset as well as select an appropriate discount rate to be used in discounting future lease payments. These estimates are utilized by management in making computations as required by existing accounting standards that determine whether the lease is classified as an operating lease or a capital lease. 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. Additionally, operating leases are not reflected in our consolidated balance sheets and accordingly, neither a lease asset nor an obligation for future lease payments is reflected in our consolidated balance sheets. 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. See Note 3: "Recent Accounting Pronouncements" in the notes to our consolidated financial statements below for a discussion of a new accounting standard that is likely to have an impact on our aircraft lease accounting beginning in 2020. Income Taxes Income taxes are accounted for using the asset and liability method. Under this method, deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which we cannot conclude that it is more likely than not that such deferred tax assets will be realized. 60 In determining the amount of the valuation allowance, estimated future taxable income, as well as feasible tax planning strategies for each taxing jurisdiction, are considered. If we determine it is more likely than not that all or a portion of the remaining deferred tax assets will not be realized, the valuation allowance will be increased with a charge to income tax expense. Conversely, if we determine we are more likely than not to be able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been provided, the related portion of the valuation allowance will be recorded as a reduction to income tax expense. We recognize and measure benefits for uncertain tax positions using a two-step approach. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that is it more likely than not that the tax positions will be sustained upon audit, including resolution of any related appeals or litigation processes. For tax positions that are more likely than not to be sustained upon audit, the second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon settlement. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Significant judgment is required to evaluate uncertain tax positions. Evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of tax audits and effective settlement of audit issues. Changes in the recognition or measurement of uncertain tax positions could result in material increases or decreases in income tax expense in the period in which the change is made, which could have a material impact to our effective tax rate. See Note 12: "Income Taxes" in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information. See also "Management's Discussion and Analysis—Results of Operations—Income Taxes" for additional information. For a further listing and discussion of our accounting policies, see Note 2: "Summary of Significant Accounting Policies" in the notes to our audited consolidated financial statements included elsewhere in this Annual Report on Form 10-K. Accounting Methodology for Stock Appreciation Rights Our SARs and the restricted stock units granted under our Restricted Phantom Stock Units Plan ("Phantom Stock") historically were accounted for as liability compensatory awards under Accounting Standards Codification ("ASC") 710, Compensation – General, valued using the intrinsic value method, as permitted by ASC 718, Compensation – Stock Compensation ("ASC 718"), for nonpublic entities. Upon becoming a public company, as defined in ASC 718, in the third quarter of our fiscal 2018, we were required to change our methodology for valuing our SARs and Phantom Stock. Accordingly, our SARs and Phantom Stock were re-measured at each quarterly reporting date and were accounted for prospectively at fair value using a Black-Scholes fair value pricing model, until they were converted to restricted stock awards in connection with our IPO. We recorded the impact of the change in valuation methods as a cumulative effect of a change in accounting principle, as permitted by ASC 250, Accounting Changes and Error Corrections. The effect of the change increased our SARs and Phantom Stock liability by $2.4 million, which was the difference in compensation cost measured using the intrinsic value method and the fair value method. An equal and offsetting change to retained earnings in the consolidated balance sheet was recorded with the revaluation. In connection with our IPO, our SARs and Phantom Stock were cancelled and exchanged for shares of restricted stock under our 2018 Equity Incentive Plan. Emerging Growth Company Status The JOBS Act permits an "emerging growth company" such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have irrevocably elected to "opt out" of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies. Recent Accounting Pronouncements For a discussion of recent accounting pronouncements, see Note 3: "Recent Accounting Pronouncements" in the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K. 61 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 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 September 30, 2019, we had $572.6 million of variable rate debt including current maturities. A hypothetical 50 basis point change in market interest rates would have increased interest expense by approximately $3.0 million in our fiscal year ended September 30, 2019. As of September 30, 2019, we had $289.3 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 September 30, 2019. 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. 62 ITEM 8.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Mesa Air Group, Inc. and subsidiaries (the "Company") as of September 30, 2019 and 2018, the related consolidated statements of operations, stockholders' equity, and cash flows, for each of the three years in the period ended September 30, 2019, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended September 30, 2019, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ Deloitte & Touche LLP Phoenix, Arizona December 16, 2019 We have served as the Company's auditor since fiscal year 2000. 64 Part I – Financial Information Item 1.

Notes to Consolidated Financial Statements (Unaudited) 1. Organization and Operations The Company 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, 2019, the Company served 125 cities in 39 states, the District of Columbia, Canada, Mexico and Cuba, and operated a fleet of 145 aircraft with approximately 730 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, 2019, 2018 and 2017 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. 69 American Capacity Purchase Agreement As of September 30, 2019, the Company operated 62 CRJ-900 aircraft for American under a capacity purchase agreement. Unless otherwise extended or amended, the capacity purchase agreement for the aircraft expires between 2021 and 2025. In exchange for providing flights and all other services under the agreement, the Company receives a fixed monthly minimum amount per aircraft, plus certain additional amounts based upon the number of flights and block hours (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) flown during the month. In addition, the Company may also receive incentives or pay penalties based upon the Company's operational performance, including controllable on-time departure and controllable completion percentages. American also reimburses the Company for the actual amount incurred for certain items such as passenger liability and hull insurance, and aircraft property taxes. In addition, American also provides, at no cost to the Company, certain ground handling and customer service functions, as well as airport- related facilities and fuel. The Company also receives a monthly profit margin payment from American based on the number of aircraft operating. The capacity purchase agreement is subject to early termination for cause under specified circumstances and subject to the Company's right to cure under certain conditions. American had a 7.1% and 7.2% ownership interest in the Company, calculated on a fully-diluted basis as of September 30, 2019 and 2018, respectively. The related party amounts presented on the consolidated balance sheets and statements of operations pertain to American. 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. As of August 28, 2019, the Company had failed to meet certain performance metrics under the Term Sheet (the "August Failure"), which failure gave rise to American’s right to permanently withdraw two additional aircraft from the American CPA. In a separate agreement, American agreed to forbear from exercising its right to permanently withdraw these two aircraft. Under the terms of such forbearance, the Company and American agreed to reset the measurement period for certain performance metrics effective as of August 29, 2019. The parties also agreed that if the Company is out of compliance with applicable performance metrics on or after September 30, 2019, American retains the right to exercise its withdrawal rights for the August Failure by delivering 60 day prior written notice to the Company. United Capacity Purchase Agreement As of September 30, 2019, 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. 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. In February 2018, we mutually agreed with United to temporarily remove two aircraft from service under our United Capacity Purchase Agreement. In July 2018, we were able to fully staff flight operations and these aircraft were placed back into service. During the temporary removal, we agreed to pay the lease costs associated with the two E-175 aircraft, which totaled $1.9 million as of September 30, 2018. 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. 70 On November 26, 2019, we amended and restated our United Capacity Purchase Agreement to, among other things, incorporate the terms of the 11 prior amendments to that Agreement and 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 Mesa and operated for a period of twelve (12) years from the in-service date. Deliveries of the new E175LL aircraft are scheduled to begin in May 2020 and be completed by December 31, 2020. 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, with Mesa continuing to operate such aircraft until they are transitioned over the period between May 2020 and December 2020. In addition, we own 18 E-175 aircraft that expire in 2028. United has a right to purchase the CRJ 700 aircraft at the then fair market value. The capacity purchase agreement is also subject to early termination for cause under specified circumstances and subject to the Company's right to cure under certain circumstances. United is also permitted, subject to certain conditions, to terminate the agreement early in its discretion by giving us notice of 90 days or more. 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying 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. The Company is an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act") and may remain an emerging growth company until the last day of our fiscal year following the fifth anniversary of the 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. Use of Estimates The preparation of the Company's 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 consolidated financial statements. Actual results could differ from those estimates. Segment Reporting 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 flying services in accordance with our capacity purchase agreements. 71 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 uses 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. He 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. All of our operating revenue in our 2019, 2018 and 2017 fiscal years was derived from operations associated with our American and United Capacity Purchase Agreements. It is currently impractical to provide certain information on our revenue from our customers for each of our services and geographic information on our revenues and long lived assets. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Marketable Securities The Company's investments in marketable securities are deemed by management to be available-for-sale and are reported at fair market value. The Company's holdings of marketable securities as of September 30, 2019 and 2018 was $0.0 million and $19.9, respectively. Restricted Cash Restricted cash primarily includes deposits in trust accounts to collateralize letters of credit and to fund workers' compensation claims, landing fees, and other business needs. Restricted cash is stated at cost, which approximates fair value. The Company has an agreement with a financial institution for a $6.0 million letter of credit facility to issue letters of credit for landing fees, workers' compensation insurance, and other business needs. Pursuant to such agreement, $3.6 million and $3.8 million of outstanding letters of credit are required to be collateralized by amounts on deposit as of September 30, 2019 and 2018, respectively, which are classified as restricted cash. Expendable Parts and Supplies Expendable parts and supplies are stated at the lower of cost (using the first-in, first-out method) or market, and are charged to expense as they are used. The Company provides an allowance for obsolescence for such parts and supplies over the useful life of its aircraft after considering the useful life of each aircraft fleet, the estimated cost of expendable parts expected to be on hand at the end of the useful life, and the estimated salvage value of the parts. This allowance was $2.4 million and $1.8 million as of September 30, 2019 and 2018, respectively. Prepaid Expenses Prepaid expenses consist primarily of the excess of aircraft lease payments over the straight-lined lease expense. The straight-lined lease expense is net of estimated rebates to be received from the lessor during the term of the agreements, contingent on the Company performing certain engine restorations. Property and Equipment Property and equipment are stated at cost, net of manufacturer incentives, and depreciated over their estimated useful lives to their estimated salvage values, which are 20% for aircraft and rotable spare parts, using the straight-line method. 72 Estimated useful lives of the various classifications of property and equipment are as follows: Property and Equipment Buildings Aircraft Flight equipment Equipment Furniture and fixtures Vehicles Rotable spare parts Leasehold improvements Estimated Useful Life 30 years 25 years from manufacture date 7-20 years 5-9 years 3-5 years 5 years Life of the aircraft or term of the lease, whichever is less Life of the aircraft or term of the lease, whichever is less Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may be impaired. The Company records an impairment loss if (i) the undiscounted future cash flows are found to be less than the carrying amount of the asset or asset group, and (ii) the carrying amount of the asset or asset group exceeds fair value. If an impairment loss has occurred, a charge is recorded to reduce the carrying amount of the asset to its estimated fair value. The Company recognized no impairment charges on property and equipment for the years ended September 30, 2019 and 2018. Fair Value Measurements The Company accounts for assets and liabilities in accordance with accounting standards that define fair value and establish a consistent framework for measuring fair value on either a recurring or a nonrecurring basis. Fair value is an exit price representing the amount that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Accounting standards include disclosure requirements relating to the fair values used for certain financial instruments and establish a fair value hierarchy. The hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of three levels: (cid:3) (cid:3) (cid:3) Level 1 – Observable inputs such as quoted prices in active markets; Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Prepaid Maintenance Deposits Prepaid maintenance deposits consist of payments made on a monthly basis to cover certain future maintenance events for leased flight equipment. The deposits are contractual obligations that are held in trust by the lessors. The deposits are only to be used to cover maintenance events, which include, among other things, C-checks, engine restoration events, engine life limited parts, landing gear repairs, and auxiliary power unit overhauls. The Company expenses the service as it is performed and receives reimbursement from the reserve trust account. The current portion is included in prepaid expenses and other current assets and the noncurrent portion is included in other assets on the consolidated balance sheet. Debt Financing Costs Debt financing costs consist of payments made to issue debt related to the purchase of aircraft, flight equipment, and certain flight equipment maintenance costs. The Company defers the costs and amortizes them over the term of the debt agreement. Debt financing costs related to a recognized debt liability are presented as a direct deduction from the carrying amount of the related long-term debt on the consolidated balance sheet. Debt financing costs with no related recognized debt liability are presented as assets, with the current portion included in prepaid expenses and other current assets and the noncurrent portion included in other assets on the consolidated balance sheet. 73 Unutilized Manufacturer Credits Manufacturer credits received in connection with aircraft purchases that can be used for the future purchase of certain goods and services are recorded as a prepaid asset based on the value of the credits expected to be utilized, and the Company reduces the asset as the credits are utilized to fund such purchases. The current portion is included in prepaid expenses and other current assets and the noncurrent portion is included in other assets on the consolidated balance sheet. Intangibles Customer relationships are amortized using future discounted cash flows over the estimated life. In accordance with ASC 360, Property, Plant and Equipment, an intangible asset with a finite life that is being amortized is reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may be impaired. The Company records an impairment loss if the undiscounted future cash flows are found to be less than the carrying amount of the asset and if the carrying amount of the asset exceeds fair value. If an impairment loss has occurred, a charge is recorded to reduce the carrying amount of the asset to its estimated fair value. Other Assets Other long-term assets primarily consist of noncurrent deferred reimbursed costs, debt financing costs, and prepaid maintenance deposits. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in future years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records deferred tax assets for the value of benefits expected to be realized from the utilization of alternative minimum tax credit carryforwards, capital loss carryforwards, and state and federal net operating loss carryforwards. The Company periodically reviews these assets to determine the likelihood of realization. To the extent the Company believes some portion of the benefit may not be realizable, an estimate of the unrealized position is made and a valuation allowance is recorded. The Company and its consolidated subsidiaries file a consolidated federal income tax return. Other Noncurrent Liabilities Other noncurrent liabilities consist of the remaining fair value adjustment for unfavorable aircraft operating leases related to a previous bankruptcy and related accounting. This adjustment to fair value is being amortized on a straight-line basis over the remaining initial lease terms for these aircraft. During each of the years ended September 30, 2019, 2018 and 2017, the Company recorded amortization of this unfavorable lease liability of $5.7 million, $6.6 million, and $6.8 million, respectively, as a reduction of lease expense. During the year ended September 30, 2019 and 2018, the Company wrote off $0.75 million and $1.2 million of unfavorable lease liability related to the lease termination of its aircraft lease facility with Wells Fargo Bank Northwest, National Association, as owner trustee and lessor (the "GECAS Lease Facility"), which was accounted for as lease termination expense. Adoption of New Revenue Standard On October 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09" or "ASC 606") using the modified retrospective method. See Note 3: "Recent Accounting Pronouncements" in the notes to our consolidated financial statements for more information. To conform to ASC 606, the Company modified its revenue recognition policy as described below. 74 Revenue Recognition The Company recognizes revenue when the service is provided under its capacity purchase agreements. Under these agreements, the major airline partners generally pay a fixed monthly minimum amount per aircraft, plus certain additional amounts based upon the number of flights and block hours flown. The contracts also include reimbursement of certain costs incurred by the Company in performing flight services. These costs, known as "pass-through costs," may include passenger and hull insurance as well as aircraft property taxes. Additionally, for the E-175 aircraft owned by United, the capacity purchase agreement provides that United will reimburse the Company for heavy airframe and engine maintenance, landing gear, APUs and component maintenance. The Company also receives compensation under its capacity purchase agreements for heavy maintenance expenses at a fixed hourly rate or per aircraft rate for all aircraft in scheduled service other than the E-175 aircraft owned by United. The contracts also include a profit margin on certain reimbursable costs, as well as a profit margin, incentives and penalties based on certain operational benchmarks. The Company is eligible to receive incentive compensation upon the achievement of certain performance criteria defined in the capacity purchase agreements. At the end of each period during the term of an agreement, the Company calculates the incentives achieved during that period and recognizes revenue attributable to the agreement during the period accordingly, subject to the variable constraint guidance under ASC 606. All revenue recognized under these contracts is presented as the gross amount billed to the major airline partners. Under the capacity purchase agreements, the Company has committed to perform various activities that can be generally classified into in-flight services and maintenance services. When evaluating these services, the Company determined that the nature of its promise is to provide a single integrated service, flight services, because its contracts require integration and assumption of risk associated with both services to effectively deliver and provide the flights as scheduled over the contract term. Therefore, the in-flight services and maintenance services are inputs to that combined integrated flight service. Both the services occur over the term of the agreement and the performance of maintenance services significantly effects the utility of the in-flight services. The Company's individual flights flown under the capacity purchase agreements are deemed to be distinct and the flight service promised in the capacity purchase agreements represents a series of services that should be accounted for as a single performance obligation. This single performance obligation is satisfied over time as the flights are completed. Therefore, revenue is recognized when each flight is completed. In allocating the transaction price, variable payments (i.e. billings based on flights and block hours flown, pass-through costs, etc.) that relate specifically to the Company's efforts in performing flight services are recognized in the period in which the individual flight is completed. The Company has concluded that allocating the variability directly to the individual flights results in an overall allocation meeting the objectives in ASC 606. This results in a pattern of revenue recognition that follows the variable amounts billed from the Company to their customers. 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 consolidated statements of operations. The Company recognized $219.0 million, $217.0 million and $217.6 million of lease revenue for the twelve months ended September 30, 2019, 2018 and 2017, 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. The Company's capacity purchase agreements are renewable periodically and contain provisions pursuant to which the parties could terminate their respective agreements, subject to certain conditions as described in Note 1. The capacity purchase agreements also contain terms with respect to covered aircraft, services provided and compensation as described in Note 1. The capacity purchase agreements are amended from time to time to change, add or delete terms of the agreements. The Company's revenues could be impacted by a number of factors, including amendment or termination of its capacity purchase agreements, contract modifications resulting from contract renegotiations, its ability to earn incentive payments contemplated under applicable agreements, and settlement of reimbursement disputes with the Company's major airline partners. In the event contracted rates are not finalized at a quarterly or annual financial statement date, the Company evaluates the enforceability of its contractual terms and when it has an enforceable right, it estimates the amount the Company expects to be entitled to that is subject to the ASC 606 constraint. 75 The Company's capacity purchase agreements contain an option that allows its major airline partners to assume the contractual responsibility for procuring and providing the fuel necessary to operate the flights that it operates for them. Both of the Company's major airline partners have exercised this option. Accordingly, the Company does not record an expense or revenue for fuel and related fueling costs for flying under its capacity purchase agreements. In addition, the Company's major airline partners also provide, at no cost to the Company, certain ground handling and customer service functions, as well as airport-related facilities and gates at their hubs and other cities. Services and facilities provided by the Company's major airline partners at no cost are presented net in its condensed consolidated financial statements; hence, no amounts are recorded for revenue or expense for these items. Contract Liabilities 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 consolidated balance sheets. The Company's total current and non-current deferred credit balances at September 30, 2019, September 30, 2018 and September 30, 2017 are $12.1 million, $15.4 million and $17.2 million respectively. The Company recognized $5.1 million, $4.4 million and $3.8 million of the deferred credits to revenue in the consolidated statements of operations during the twelve months ended September 30, 2019, 2018 and 2017, respectively. Contract Assets 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 consolidated balance sheets. The Company's contract assets balances at September 30, 2019, September 30, 2018 and September 30, 2017 are $3.9 million, $4.6 million and $6.1 million, respectively. Contract cost amortization was $2.4 million, $1.9 million and $1.6 million for the twelve months ended September 30, 2019, 2018 and 2017, respectively. Maintenance Expense The Company operates under an 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 expense is recognized when the maintenance work is completed, or over the period of repair, 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 $30.0 million, $51.2 million and $64.0 million for the years ended September 30, 2019, 2018 and 2017, respectively, of which $6.0 million, $12.3 million and $0.3 million was pass-through expense. Airframe check expense totaled $17.2 million, $21.5 million and $22.6 million for the years ended September 30, 2019, 2018 and 2017, respectively, of which $0.4 million, $7.5 million and $4.9 million was pass-through expense. Pursuant to the United capacity purchase agreement, United reimburses the Company for heavy maintenance on certain E-175 aircraft. Those reimbursements are included in pass-through and other revenue. See Note 1: "Organization and Operations" for further information. 76 Aircraft Leases In addition to the aircraft we receive from United under our Capacity Purchase Agreement, approximately 12% of our aircraft are leased from third parties. In order to determine the proper classification of a lease as either an operating lease or a capital lease, we must make certain estimates at the inception of the lease relating to the economic useful life and the fair value of an asset as well as select an appropriate discount rate to be used in discounting future lease payments. These estimates are utilized by management in making computations as required by existing accounting standards that determine whether the lease is classified as an operating lease or a capital lease. 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. Additionally, operating leases are not reflected in our consolidated balance sheets and accordingly, neither a lease asset nor an obligation for future lease payments is reflected in our consolidated balance sheets. 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. See Note 3: "Recent Accounting Pronouncements" in the notes to our consolidated financial statements below for a discussion of a new accounting standard that is likely to have an impact on our aircraft lease accounting beginning in fiscal year 2020. Change in Accounting Policy Stock Appreciation Rights ("SARs") and Phantom Stock historically were accounted for as liability compensatory awards under ASC 710, Compensation – General, valued using the intrinsic value method, as permitted by ASC 718, Compensation – Stock Compensation, for nonpublic entities. Upon becoming a public company, as defined in ASC 718, in the third quarter of fiscal 2018, the Company was required to change its methodology for valuing the SARs and Phantom Stock. The SARs and Phantom Stock were re-measured at each quarterly reporting date and were accounted for prospectively at fair value using a Black-Scholes fair value pricing model until they were converted to restricted stock awards upon completion of the Company's IPO. The Company recorded the impact of the change in valuation methods as a cumulative effect of a change in accounting principle, as permitted by ASC 250, Accounting Changes and Error Corrections. The effect of the change increased the SARs and Phantom Stock liability by $2.4 million which was the difference in compensation cost measured using the intrinsic value method and the fair value method. An equal and offsetting change to retained earnings in the consolidated balance sheet was recorded with the revaluation. Any future changes in fair value were recorded as compensation expense in the consolidated statement of operations. Upon completion of the Company's IPO the SARs and Phantom Stock were cancelled and exchanged for shares of restricted stock under our 2018 Plan. 3. Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASC 606 establishes a new recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be entitled in exchange for those goods or services. On October 1, 2018, the Company adopted this ASU using the modified retrospective method. Under the new standard, the Company concluded that, in addition to the aircraft lease, the individual flights are distinct services and the flight services promised in the capacity purchase agreements represent a series of services that should be accounted for as a single performance obligation. Revenue is recognized over time as the flights are completed. The adoption of this ASU did not have an impact on recorded amounts when applied to the opening balance sheet as of October 1, 2018. The adoption did not impact the condensed consolidated financial statements presented other than the disclosures noted in Note 2: "Summary of Significant Accounting Policies." In August 2014, The FASB issued ASU No. 2014-15, Presentation of Financial Statements—Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (Topic 205), which provides guidance on determining when and how to disclose going-concern uncertainties in the consolidated financial statements. The new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date the consolidated financial statements are issued. An entity must provide certain disclosure if "conditions or events raise substantial doubt about the entity's ability to continue as a going concern." The update applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter. The Company adopted this ASU in fiscal year 2018, and the adoption did not have a material impact on the consolidated financial statements. 77 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 guidance is effective for annual periods beginning after December 15, 2018, with early adoption permitted. Based on the Company's initial assessment, the adoption of Topic 842 will significantly increase the Company's assets and liabilities primarily to reflect its aircraft operating lease liability and related right-of-use asset. As of September 30, 2019, the Company had 18 leased aircraft under operating leases in its fleet. The Company also has leases for a nominal fee for 42 aircraft owned by United, spare engines and other real estate leases. The Company does not expect the adoption of the New Lease Standard to impact any of its existing debt covenants. Additionally, the Company does not expect the adoption to 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 does not anticipate the adoption of Topic 842 will have a material impact on the timing or amount of the Company's lease revenue as a lessor. The Company will adopt Topic 842 on October 1, 2019. The Company expects to elect several of the practical expedients available under the transition provisions of Topic 842, including (i) not reassessing whether expired or existing contracts contain leases, (ii) lease classification, and (iii) not revaluing initial direct costs for existing leases. The Company plans to elect the practical expedient which will allow aggregation of non-lease components with the related lease components when evaluating accounting treatment. Also, the Company plans to not apply Topic 842 to leases that, at the commencement date, have a lease term of 12 months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. Lastly, the Company currently plans to apply the modified retrospective adoption method, utilizing the simplified transition option available in Topic 842, which allows entities to continue to apply the legacy guidance in ASC 840, including its disclosure requirements, in the comparative periods presented in the year of adoption. Upon adoption, the Company anticipates it will reflect a lease liability in the range of $130 to $170 million and a right-of- use asset of $120 to $180 million. Upon adoption, the right-of-use asset is expected to include prepaid aircraft rents, accrued aircraft rents and deferred rent credits that were separately stated in the Company's September 30, 2019 balance sheet. These estimates are subject to revision based upon the Company's adoption of Topic 842 in fiscal year 2020. In March of 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). With this standard, all excess tax benefits and tax deficiencies are required to be recognized as income tax benefit or expense in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company adopted ASU 2016-09 in the first quarter of the year ended September 30, 2018. This change in accounting principle has been applied on a modified retrospective transition method by means of a cumulative effect adjustment to equity as of the beginning of fiscal year 2018 as a cumulative-effect adjustment increasing deferred tax assets by $0.4 million, increasing income tax expense by $0.3 million, and increasing retained earnings by $0.7 million. Adoption of ASU 2016-09 did not have any other material effect on the Company's results of operations, financial position or cash flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force), which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company adopted the standard effective October 1, 2018; the adoption of this standard did not have a material impact on the financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force), that requires restricted cash and cash equivalents to be included with cash and cash equivalents on the statement of cash flows. The new standard is effective for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company adopted the standard effective October 1, 2018 and modified the presentation to include changes in restricted cash in the Company's Consolidated Statement of Cash Flows. 78 4. Concentrations At September 30, 2019, the Company had capacity purchase agreements with American and United. All of the Company's consolidated revenue for the years ended September 30, 2019, 2018 and 2017 and accounts receivable at the end of September 30, 2019 and 2018 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. As of September 30, 2019, we had 17 aircraft with leases extending past the term of their corresponding capacity purchase agreements which results in a significant amount of an aggregate exposure and no financing arrangements with projected negativity. We intend to continue to align the terms of our aircraft leases and financing agreements with the terms of our capacity purchase agreements in order to maintain low "tail risk." 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 $1.0 million and $1.3 million at September 30, 2019 and 2018, respectively. If the Company's ability to collect these receivables and the financial viability of our partners is materially different than estimated, the Company's estimate of the allowance could be materially impacted. American accounted for approximately 53%, 54% and 56% of the Company's total revenue for the years ended September 30, 2019, 2018 and 2017, respectively. United accounted for approximately 47%, 46% and 44% of the Company's total revenue for the years ended September 30, 2019, 2018 and 2017, 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. 5. Intangible Assets Information about the intangible assets of the Company at September 30, 2019 and 2018, were as follows (in thousands): Customer relationship Accumulated amortization September 30, September 30, 2019 2018 $ $ 43,800 $ (34,268) 9,532 $ 43,800 (32,459) 11,341 Total amortization expense recognized was approximately $1.8 million, $0.4 million and $0.4 million for the fiscal years ended September 30, 2019, 2018 and 2017. The Company expects to record amortization expense of $1.5 million, $1.2 million, $1.0 million, $0.9 million and $0.8 million for fiscal years 2020, 2021, 2022, 2023, 2024 respectively. 79 6. Balance Sheet Information Certain significant amounts included in the Company's consolidated balance sheet as of September 30, 2019 and 2018, consisted of the following (in thousands): Expendable parts and supplies, net Expendable parts and supplies Less obsolescence and other Prepaid expenses and other current assets Prepaid aircraft rent Unutilized manufacturer credits Deferred offering and reimbursed costs Other Property and equipment—net Aircraft and other flight equipment substantially pledged Other equipment Leasehold improvements Vehicles Building Furniture and fixtures Total property and equipment Less accumulated depreciation Other accrued expenses Accrued property taxes Accrued interest Accrued vacation Accrued wheels, brakes and tires Other September 30, September 30, 2019 2018 $ $ $ $ 25,336 $ (3,999) 21,337 $ 35,786 $ — 2,092 3,045 40,923 $ 18,907 (3,249) 15,658 30,267 4,500 1,945 4,202 40,914 5,122 2,797 924 699 302 $ 1,582,199 $ 1,502,940 3,721 2,754 692 699 287 1,592,043 1,511,093 (260,264) $ 1,273,585 $ 1,250,829 (318,458) $ $ 9,186 $ 4,497 6,128 1,513 7,564 28,888 $ 6,981 6,118 5,470 1,452 9,675 29,696 Depreciation expense totaled $76.2 million, $64.6 million and $60.7 million for the years ended September 30, 2019, 2018 and 2017, respectively. The Company recorded amortization of the unfavorable lease liability amounting to $5.7 million, $6.6 million and $6.8 million for the years ended September 30, 2019, 2018 and 2017, respectively, as a reduction to lease expense. During the year ended September 30, 2019 and 2018 the Company wrote off $0.8 million and $1.2 million of unfavorable lease liability related to the lease termination of its aircraft lease facility with Wells Fargo Bank Northwest, National Association, as owner trustee and lessor (the "GECAS Lease Facility"), which was accounted for as lease termination expense. 7. Fair Value Measurements The Company did not measure any of its assets or liabilities at fair value on a recurring or nonrecurring basis as of September 30, 2019 and 2018. The carrying values of cash and cash equivalents, accounts receivable, and accounts payable included on the consolidated balance sheets approximated fair value at September 30, 2019 and 2018. 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. 80 The carrying value and estimated fair value of the Company's long-term debt, including current maturities, were as follows (in millions): Carrying September 30, 2019 Fair Value Value September 30, 2018 Fair Value Carrying Value Long-term debt, including current maturities(1) $ 858.1 $ 882.7 $ 930.2 $ 926.2 (1) Current and prior period long-term debts' carrying and fair values exclude net debt issuance costs. 8.

In fiscal 2015, the Company financed seven CRJ-900 aircraft with $170.2 million in debt. The senior notes payable of $151 million bear interest at monthly LIBOR plus 2.71% (4.730% at September 30, 2019) and require monthly principal and interest payments. The subordinated notes payable are noninterest-bearing and become payable in full on the last day of the term of the notes. The Company has imputed an interest rate of 6.25% on the subordinated notes payable and recorded a related discount of $8.1 million, which is being accreted to interest expense over the term of the notes. In fiscal 2017, the Company financed 10 E-175 aircraft with $246 million in debt under an EETC financing arrangement (see discussion below). The debt bears interest ranging from 4.75% to 6.25% and requires semi- annual principal and interest payments. In fiscal 2017, the Company financed eight E-175 aircraft with $195.3 million in debt. The senior notes payable of $172 million bear interest at the three-month LIBOR plus a spread ranging from 2.20% to 2.32% (4.290% to 4.410% at September 30, 2019) and require quarterly principal and interest payments. The subordinated notes payable bear interest at 4.50% and require quarterly principal and interest payments. In fiscal 2018, the Company financed certain flight equipment with $99.1 million in debt. The debt bears interest at the monthly LIBOR (rounded to the nearest 16th) plus 7.25% and requires monthly principal and interest payments. As of September 30, 2019, the loan has been repaid. In December 2017, the Company refinanced nine CRJ-900 aircraft with $74.9 million in debt.

The subordinated notes payable bear interest at the three-month LIBOR plus 4.50% (6.590% at September 30, 2019) and require quarterly principal and interest payments. In fiscal 2015, the Company financed certain flight equipment with $8.3 million in debt. The debt bears interest at 5.163% and requires monthly principal and interest payments. In fiscal 2015 and 2017, the Company financed certain flight equipment maintenance costs with $10.2 million in debt. The debt bears interest at the three-month LIBOR plus 3.07% (5.160% at September 30, 2019) and requires quarterly principal and interest payments. In fiscal 2017 and 2018, the Company financed certain flight equipment maintenance costs with $11.9 million in debt. The debt bears interest at the three-month LIBOR plus a spread ranging from 2.93% to 2.96% (5.020% to 5.050% at September 30, 2019) and requires quarterly principal and interest payments. The debt is subject to a fixed charge ratio covenant. As of September 30, 2019, the Company was in compliance with this covenant. In fiscal 2018, the Company financed certain flight equipment maintenance costs with $25.0 million in debt. The debt bears interest at the three-month LIBOR plus 3.30% and requires quarterly principal and interest payments. The debt is subject to a fixed charge ratio covenant. As of September 30, 2019, the loan has been repaid. In February 2018, the Company leased two spare engines. The leases were determined to be capital as the leases contain a bargain purchase option at the end of the term. Imputed interest is 9.128% and the leases requires monthly payments. In June 2018, the Company refinanced six CRJ-900 aircraft with $27.5 million in debt and financed nine CRJ-900 aircraft, which were previously leased, with $69.6 million in debt. The senior notes payable of $65.8 million bear interest at the three-month LIBOR plus 3.50% (5.590% at September 30, 2019) and require quarterly principal and interest payments.

The debt bears interest at the monthly LIBOR plus 5.25% (7.27% at September 30, 2019) and requires monthly principal and interest payments. As of September 30, 2019 we had $8.0 million outstanding under these notes. 82 Principal maturities of long-term debt as of September 30, 2019, and for each of the next five years are as follows (in thousands): Periods Ending September 30, 2020 2021 2022 2023 2024 Thereafter Total Principal Amount 165,900 161,359 152,745 103,165 71,033 203,943 858,145 $ The net book value of collateralized aircraft and equipment as of September 30, 2019 was $1,203.5 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 September 30, 2019, Mesa has $191.2 million of equipment notes outstanding issued under the EETC financing included in long-term debt on the 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 June 27, 2018, the Company refinanced $16.0 million of debt on six CRJ-900 aircraft (due in 2019), with $27.5 million of debt, resulting in net cash proceeds to the Company of $10.4 million after transaction related fees. The notes payable require quarterly payments of principal and interest through fiscal 2022 bearing interest at LIBOR plus 3.50%. On June 28, 2018, the Company purchased nine CRJ-900 aircraft, which were previously leased under the GECAS Lease Facility, for $76.5 million. The Company financed the aircraft purchase with $69.6 million in new debt and proceeds from the June 2018 refinancing of six CRJ-900 aircraft. The notes payable of $69.6 million require quarterly payments of principal and interest through fiscal 2022 bearing interest at LIBOR plus a spread ranging from 3.50% for the senior promissory notes to 7.50% for the subordinated promissory notes. The Company recorded non-cash lease termination expense of $15.1 million in connection with the lease buyout. Also, as part of the transaction, the Company (i) received $4.5 million of future goods and services credits and $5.6 million of loan forgiveness for loans with a maturity date in 2027 from the aircraft manufacturer, and (ii) mutually agreed with GE Capital Aviation Services LLC to terminate the GE Warrant to purchase 250,000 shares of common stock. On January 28, 2019, the Company entered into a Term Loan Agreement (the "Term Loan") pursuant to which the lenders thereunder lent 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 above), 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. 83 On June 14, 2019, the Company completed the purchase of ten CRJ-700 aircraft, which were previously leased under 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 5.25%. 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 $35 million working capital draw loan by three years, which now terminates in September 2022. Interest is assessed on drawn amounts at one-month LIBOR plus 3.75%. On September 27, 2019, the company financed certain flight equipment for $8.0 million in new debt. The debt of $8.0 million require monthly payments of principal and interest through fiscal 2023 bearing interest at Libor plus 5.25%. 9. Earnings Per Share Calculations of net income per common share were as follows (in thousands, except per share data): Net income Basic weighted average common shares outstanding $ Add: Incremental shares for: Dilutive effect of warrants Dilutive effect of restricted stock Diluted weighted average common shares outstanding Year Ended September 30, 2018 33,255 24,826 2019 47,580 34,764 $ $ — 300 35,064 116 315 25,257 2017 32,828 23,201 93 76 23,370 Net income per common share Basic Diluted $ $ 1.37 1.36 $ $ 1.34 1.32 $ $ 1.41 1.40 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 no anti-dilutive shares relating to restricted stock and exercise of warrants that were excluded from the calculation of diluted loss per share for the years ended September 30, 2019, 2018 and 2017. 10. Restatement Basic and Diluted Net Income per Common Share Available to Common Shareholders: Subsequent to the issuance of the Company's consolidated financial statements for the year ended September 30, 2018, we determined our previously issued consolidated financial statements included warrants with a nominal conversion price in diluted income per common share available to common shareholders, however, they should have been included in basic income per common share available to common shareholders. As a result, basic income per common share available to common shareholders for the years ended September 30, 2018 and 2017 have been restated to appropriately include the warrants with a nominal conversion price in basic income per common share available to common shareholders. Since diluted shares are under the treasury stock method, diluted common share available to common shareholders were impacted by this change and have been restated. 84 The restatement adjustment did not impact our previously reported consolidated balance sheet, consolidated statements of stockholders' equity, consolidated statements of cash flows, or net income (in thousands, except per share data).

Certain persons who are not U.S. citizens currently hold outstanding warrants to purchase shares of the Company's common stock. The warrants are exercisable if consistent with federal law, which requires that no more than 24.9% of the Company's stock be voted, directly or indirectly, or controlled by persons who are not U.S. citizens. The warrants can be converted to common stock upon warrant holders demonstrating U.S. citizenship or if consistent with above described federal law ownership limitations. In June 2018, the Company and holders agreed to extend the term of outstanding warrants set to expire by five years (through fiscal year 2023). On June 28, 2018, the Company agreed with GE Capital Aviation Services LLC ("GE Capital") to terminate a warrant to purchase 250,000 shares of common stock held by GE Capital. In July 2018, the Company's Board of Directors and Compensation Committee approved the issuance of shares of restricted common stock under its 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 consolidated financial statements have been retrospectively revised to reflect the stock split and increase in authorized shares. 85 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. We 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, 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 resulting in a total of 3,500,000 authorized shares. 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. 12.

The Company believes that it is more likely than not that the benefit from certain state NOL carryforwards will not be realized. In recognition of this risk, the Company has provided a valuation allowance of $1.9 million in fiscal year 2019 and $1.9 million in fiscal year 2018 on the deferred tax assets related to these state NOL carryforwards. If or when recognized, the tax benefits related to any reversal of the valuation allowance on deferred tax assets will be recognized as a reduction of income tax expense. The federal and state NOL carryforwards in the income tax returns filed included unrecognized tax benefits. The deferred tax assets recognized for those NOLs are presented net of these unrecognized tax benefits. Because of the change of ownership provisions of the Tax Reform Act of 1986, use of a portion of our NOL and tax credit carryforwards may be limited in future periods. Further, a portion of the carryforwards may expire before being applied to reduce future income tax liabilities. The initial public offering in August of 2018 resulted in a change in ownership under Section 382 of the Internal Revenue Code. Based on the valuation of the Company's stock as of the initial public offering date, the Company does not believe any limitation on the utilization of the Company's current net operating losses would be applicable as of September 30, 2019. The following is a tabular reconciliation of the total amounts of unrecognized tax benefits: Unrecognized tax benefits — October 1 Gross decreases — tax positions in prior period Unrecognized tax benefits — September 30 2019 Years Ended September 30, 2018 (in thousands) 2017 $ $ 4,688 $ — 4,688 $ 7,547 $ (2,859) 4,688 $ 7,547 — 7,547 The Company’s unrecognized tax benefits of $4.7 million, $4.7 million and $7.5 million as of September 30, 2019, 2018 and 2017, respectively, is included the net deferred tax assets. If recognized, the balance of the uncertain tax benefit would affect the effective tax rate. We recognize interest accrued related to unrecognized tax benefits and penalties as income tax expense. We have not recorded accrued penalties or interest related to the unrecognized tax benefits noted above as the amounts would result in an adjustment to NOL carry forwards. 87 We are subject to taxation in the United States and various states. As of September 30, 2019, the Company is no longer subject to U.S. federal or state examinations by taxing authorities for fiscal years prior to 1999. The Tax Cuts and Jobs Act (the "Tax Act") made broad and complex changes to the U.S. tax code that affected the Company's fiscal year ended September 30, 2018, including but not limited to (1) reducing the U.S. federal corporate tax rate, (2) changing rules related to uses and limitations of NOL carryforwards created in tax years beginning after December 31, 2017, (3) eliminating the corporate alternative minimum tax ("AMT") and changing how existing AMT credits can be realized, and (4) altering bonus depreciation rules that will allow for full expensing of qualified property. The Tax Act reduced the federal corporate tax rate to 21% in the Company's fiscal year ended September 30, 2018 for the period beginning after December 31, 2017. For the fiscal year ended September 30, 2019, and onward, the applicable federal corporate tax rate is 21%. The SEC staff issued SAB 118, which provided guidance on accounting for the tax effects of the Tax Act. SAB 118 provided a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company was required to reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 was complete. To the extent that a company's accounting for certain income tax effects of the Tax Act was incomplete, but it was able to determine a reasonable estimate, it was required to record a provisional estimate in the financial statements. If a company was not able to determine a provisional estimate to be included in the financial statements, it continued to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The one year measurement period ended during the Company's first quarter ended December 31, 2018. As a result, the Company finalized provisional amounts originally recorded in connection with the Tax Act in the first quarter of the fiscal year ended September 30, 2019. In connection with the Company's initial analysis of the impact of the Tax Act, it recorded a discrete net tax benefit of $22.4 million in the period ended September 30, 2018. The Company completed its accounting for the income tax effects of the Tax Act. The Company's accounting for the Tax Act was completed as follows: Reduction of U.S. federal corporate tax rate: The Act reduced the corporate tax rate to 21%, effective January 1, 2018. In the fourth quarter of the period ended September 30, 2018, the Company completed its analysis to determine the effect of the reduction of the U.S. federal corporate tax rate and recorded an adjustment of $0.9 million from the amount recorded in the first quarter of the 2018 fiscal year. Consequently, the effect for the fiscal year ended September 30, 2018 was a decrease related to the Company's net deferred tax liabilities of $22.0 million, excluding the valuation allowance. The Company also calculated an increase to its valuation allowance of $0.5 million due to the rate change. The Company recorded a corresponding net adjustment to its deferred income tax benefit of $21.5 million for the period ended September 30, 2018 as part of its completion of the accounting for Tax Act. For tax years beginning after December 31, 2017, the corporate AMT was repealed. AMT credits in excess of regular tax liability are refundable in the years 2018 through 2021. At September 30, 2018, the Company had $2.5 million of AMT credits, all of which is expected to be refunded. The Company has classified a portion of the refund as a current receivable and a portion has been recorded as long-term receivable as of September 30, 2019. In the first quarter of fiscal 2019, the IRS released an announcement regarding Section 53(e) which no longer subjects taxpayers to a sequestration of its AMT credit refund. As a result, the Company reversed a tax expense of approximately $0.1 million related to an estimated sequestration accrual previously recorded during the tax year ended September 30, 2018, resulting in an income tax benefit of $0.1 million for the tax year ended September 30, 2019. Valuation allowances: The Company determined whether the federal and state valuation allowance assessments were affected by various aspects of the Tax Act. Any corresponding determinations relating to changes in valuation allowances have, likewise, been completed with no changes identified with respect to the provisional amounts recorded. 88 13. Share-Based Compensation Restricted Stock In July 2018, the Company’s Board of Directors and Compensation Committee approved the issuance of shares of restricted common stock under its 2018 Plan immediately following the 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. There were 966,022 vested SARs which were cancelled, exchanged for shares of restricted common stock and issued as restricted stock upon completion of the IPO. Immediately following the IPO, 2,249,147 shares were issued to certain of its employees and directors under the 2018 Plan in exchange for the cancellation of 491,915 unvested restricted phantom stock units, 491,198 unvested restricted shares issued under the 2011 and 2017 Plans and 1,266,034 SARs (966,022 vested and 300,012 unvested). The Company has the right to withhold shares to satisfy tax withholding obligations and the withheld shares become available for future grants. The shares are valued at grant date based upon recent share transactions. From inception of the 2011 Plan through IPO, 2,448,905 shares have been granted, 1,978,550 shares have vested and 470,355 shares have been cancelled. From inception of the 2017 Plan, 31,255 shares have been granted, 10,412 have vested and 20,843 shares have been cancelled. In April 2019, the Company’s Board of Directors increased the number of authorized shares of common stock to management under the 2018 Plan from 2,500,000 to 3,500,000. From inception of the 2018 Plan, 2,571,073 shares have been awarded, 1,700,104 shares have vested and 22,995 shares have been cancelled.

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. Stock Appreciation Rights In 2014, the Company implemented a share-based payment plan under which certain executives and directors are eligible to receive grants of SARs (the "SARs Plan"). The SARs provide a participant with the right to receive the aggregate appreciation in stock price over the market price of the Company's common stock at the date of grant, payable in cash. The participant may exercise his or her SARs quarterly after the grant is vested but no later than 10 years after the date of grant. The SARs awards vest ratably over a three year period from the date of grant. The Company had authorized 5,000,000 shares under this plan and had granted 4,204,993 since inception of the plan. Since inception of the plan, 3,687,218 of SARs have vested and 2,088,333 of SARs have been exercised. In August 2018, upon IPO, 517,775 unvested SARs and 1,598,885 vested SARs were cancelled in exchange for 300,012 and 966,022 shares of restricted stock under the 2018 Plan, respectively.

The restricted phantom stock units ("restricted stock units" or "RSUs") provide a participant with the right to receive a cash or stock bonus based on the fair market value of a stated number of RSUs that are vested. The shares of Common Stock that may be subject to RSUs granted under the Plan shall not exceed an aggregate of 1,250,000 shares. All of the RSUs are non-vested and forfeitable as of the grant date and vest over a three-year period. Any vested RSU will be settled by the Company upon vesting but no later than March 15 of the calendar year after the date that the RSUs become vested. The Company had authorized 1,250,000 shares under this plan and had granted 536,538 since inception of the plan. Since inception of the plan, 44,623 RSUs have vested or settled. In August 2018, upon completion of our IPO, 491,915 unvested RSUs were cancelled in exchange for shares of restricted stock under the 2018 Plan. The phantom stock activity for the years ended September 30, 2018 were summarized as follows: Phantom stock unvested at September 30, 2017 Granted Vested Cancelled Phantom stock unvested at September 30, 2018 90 Weighted- Number Average of Shares Fair Value — $ 536,538 (44,623) (491,915) — $ — 6.14 7.30 12.00 — Following the IPO there will be no further grants under the Stock Appreciation Rights and Phantom Stock plans. Immediately following the IPO, shares of restricted common stock were issued to certain of its employees and directors under its 2018 Plan 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. As of September 30, 2019, there was $5.9 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 1.5 years. Compensation cost for share-based awards are recognized on a straight-line basis over the vesting period. Share-based compensation expense for the years ended September 30, 2019, 2018 and 2017 was $5.5 million, $12.9 million and $2.3 million, respectively. Share-based compensation expenses are recorded in general and administrative expenses in the consolidated statements of operations. The Company repurchased 205,235 shares of its common stock for $1.9 million to cover the income tax obligation on vested employee equity awards and warrant conversions during the fiscal year ended September 30, 2019. During the fiscal year ended September 30, 2018, the Company repurchased 438,541 shares of its common stock for $5.0 million to cover the income tax obligation on vested employee equity awards. 14. Employee Stock Purchase Plan 2019 ESPP 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 September 30, 2019, we had not issued any Mesa Air Group, Inc. ordinary shares under the 2019 ESPP. 15. Commitments At September 30, 2019, the Company leased 18 aircraft under non-cancelable operating leases with remaining terms of up to 4.5 years. The Company has the option to terminate certain leases at various times throughout the lease. The Company headquarters and other facility non-cancelable operating leases have remaining terms of up to 6.2 years. 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. Aggregate rental expense under all operating aircraft, equipment and facility leases totaled approximately $72.8 million, $85.9 million and $83.8 million for the years ended September 30, 2019, 2018 and 2017, respectively. Future minimum lease payments as of September 30, 2019, under non-cancelable operating leases are as follows (in thousands): 2020 2021 2022 2023 2024 Thereafter Total Periods Ending September 30, Aircraft Other $ 44,231 $ 44,314 29,751 12,418 11,849 — $ 142,563 $ 3,583 1,693 1,339 1,308 1,336 1,368 10,627 91 $ Total 47,814 46,007 31,090 13,726 13,185 1,368 $ 153,190 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. 16. Contingencies 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. 17. Selected Consolidated Quarterly Financial Data (unaudited) The following table sets forth certain unaudited selected consolidated financial information for each of the four quarters in the years ended September 30, 2019, 2018 and 2017. In management's opinion, this unaudited consolidated quarterly selected information has been prepared on the same basis as the audited consolidated financial statements and includes all necessary adjustments, consisting only of normal recurring adjustments, which management considers necessary for a fair presentation when read in conjunction with the Consolidated Financial Statements and notes. We believe these comparisons of consolidated quarterly selected financial data are not necessarily indicative of future performance. Quarterly EPS may not total to the fiscal year EPS due to the weighted average number of shares outstanding at the end of each period reported and rounding. 2019 Contract revenue Total operating revenues Operating income Net income (loss) Net (loss) income per share attributable to common shareholders Basic Diluted 2018 Contract revenue Total operating revenues Operating income Net income (loss) Net (loss) income per share attributable to common shareholders Basic Diluted 12/31/2018 First Quarter 3/31/2019 Second Quarter 6/30/2019 Third Quarter 9/30/2019 Fourth Quarter (in thousands, except per share data) $ 170,449 $ 178,156 39,230 19,081 169,771 $ 177,147 34,377 13,249 170,366 $ 180,224 17,077 3,007 172,248 187,830 30,453 12,243 0.55 0.54 0.38 0.38 0.09 0.09 0.35 0.35 12/31/2017 First Quarter 3/31/2018 Second Quarter 6/30/2018 Third Quarter 9/30/2018 Fourth Quarter (in thousands, except per share data) $ 154,389 $ 164,684 15,023 22,624 156,515 $ 167,640 16,349 2,372 159,916 $ 171,739 (508) (11,135) 168,444 177,532 41,784 19,394 0.97 0.96 0.10 0.10 (0.48) (0.48) 0.66 0.65 92 12/31/2016 First Quarter 3/31/2017 Second Quarter 6/30/2017 Third Quarter 9/30/2017 Fourth Quarter (in thousands, except per share data) $ 155,502 $ 160,235 20,838 6,610 154,210 $ 159,096 20,405 5,304 157,411 $ 166,952 36,360 15,432 151,575 157,293 22,691 5,482 0.28 0.28 0.23 0.23 0.67 0.66 0.24 0.24 2017 Contract revenue Total operating revenues Operating income Net income Net (loss) income per share attributable to common shareholders Basic Diluted Restatement Subsequent to the issuance of the Company’s condensed consolidated financial statements for the three months ended December 31, 2018, we determined our previously issued condensed consolidated financial statements included warrants with a nominal conversion price in diluted income per common share available to common shareholders, however, they should have been included in basic income per common share available to common shareholders. Since diluted shares are under the treasury stock method, diluted income per common share available to common shareholders was impacted by this change. As a result, basic and diluted income per common share available to common shareholders for the quarters ended March 31, June 30, September 30 and December 31, 2018 and 2017 and the quarter ended December 31, 2016 have been restated to appropriately include the warrants with a nominal conversion price in basic income per common share available to common shareholders. The restatement adjustment did not impact our previously reported consolidated balance sheet, consolidated statements of stockholders' equity, consolidated statements of cash flows, or net income (in thousands, except per share data).

Subsequent Events On November 26, 2019, the Company entered into an Amended and Restated Capacity Purchase Agreement with United, which amends and restates the United Capacity Purchase Agreement, dated as of August 29, 2013 (the "Original United CPA"). The Company entered into the Amended and Restated Capacity Purchase Agreement to, among other things, incorporate the terms of the 11 prior amendments to that Agreement, as well as agree upon the terms described below. The term of the Amended and Restated Capacity Purchase Agreement was extended through the addition of 20 new Embraer E175LL aircraft to the scope of such agreement, which aircraft will be financed and owned by the Company and operated for a period of 12 years from the in-service date. The addition of these new aircraft increases the Company’s Embraer fleet to 80 aircraft. Deliveries are scheduled to begin in May 2020 and be completed by December 31, 2020. Commencing five (5) years after the actual in-service date, United has the right to remove the new E175LL aircraft from service by giving the Company 90 days or more notice, 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, the Company also extended the term of the 42 E175 aircraft leased from United for an additional five (5) years. In connection with the new Embraer E175LL aircraft deliveries, the Company has agreed to lease its twenty (20) CRJ700 aircraft to another United Express service provider for a term of seven years. The form of lease or sublease is to be mutually agreed upon between the parties, subject to receipt of any required third party consents. The lessee must pay the Company a specified total per month for each aircraft plus specified supplemental rent payments for maintenance. The other United Express carrier will be responsible for all obligations under the leases. However, subject to certain limits and requirements. United will be responsible for certain unmet rent obligations under the leases. In addition, United has a right to purchase the twenty (20) CRJ700 aircraft from Mesa at fair market value before or during the lease term. On November 25, 2019, the Company amended its agreement with American Airlines. The Company did not meet certain performance metrics during the most recent measurement period, which allows American to remove two additional aircraft from the capacity purchase agreement. American has agreed to defer the right to remove these two aircraft but has elected to remove one of two previously deferred aircraft, effective January 2, 2020. One December 11, 2019, the Company entered into a purchase agreement with General Electric Company to purchase twenty (20) new spare CF34-8C5 engines. The Company expects to take delivery of the engines between August 2020 and December 2021. 94 ITEM 9.CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures Our management, including our Chief Executive Officer and Chief Financial Officer, performed an evaluation of our disclosure controls and procedures, which have been designed to ensure that information we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported accurately and within the time periods specified in the SEC rules and forms. Our management, including our Chief Executive Officer and Chief Financial Officer, concluded that, as of September 30, 2019, those controls and procedures were, in design and operations, effective at the reasonable assurance level to ensure that information we are required to disclose in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Changes in Internal Control Over Financial Reporting Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we conducted an evaluation of any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during our most recently completed fiscal quarter. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that there has not been any change in our internal control over financial reporting during that quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. Management's Annual Report on Internal Control Over Financial Reporting As required by SEC rules and regulations implementing Section 404 of the Sarbanes-Oxley Act, our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with GAAP. Our internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of our company, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors, and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect errors or misstatements in our financial statements. Also, 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 or compliance with the policies or procedures may deteriorate. Management assessed the effectiveness of our internal control over financial reporting at September 30, 2019. In making these assessments, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on our assessments and those criteria, management determined that we maintained effective internal control over financial reporting as of September 30, 2019.
