Dear Shareholder,

Let me start by telling you it’s exciting to be back in 
the public market! I would like to thank our pre-IPO 
shareholders,  airline  partners,  vendors,  and  em-
ployees for their support while we operated as a 
private company. During that time the regional air-
line  industry  changed  considerably,  and  we  have 
worked  hard  to  position  ourselves  to  re-enter  the 
public market. Today we are an efficient and high 
performing low cost operator.

Between 2013 and 2018 the Company:  

•  Added 86 large (76-seat) regional jet aircraft 
operating  under  long-term  contracts  –  more 
growth than any other regional airline
•  60 new Embraer E-175 jets operating as   
  United Express
•  26 Bombardier CRJ-900 aircraft flying as 
  American Eagle
Increased  revenues  64%  from  $415  million  in 
2013 to $681 million in 2018

• 

•  Ratified new collective bargaining agreements 
for pilots and flight attendants, providing stable 
and predictable labor costs through 2021
•  Signed  new,  cost-effective,  long-term  mainte-

nance agreements

•  Successfully  navigated  an  elevated  engine 

overhaul cycle

•  Financed over $1 billion of aircraft and engines 
•  Hired over 1,500 pilots

2018 in review

In  fiscal  year  2018,  we  consolidated  our  growth, 
solidifying the foundation for our future, and on Au-
gust  9th  we  completed  our  initial  public  offering, 
raising $112 million. 

This  year  we  finalized  and  initiated  a  number  of 
transactions that will improve our financial position. 
We  bought  nine  CRJ-900  aircraft  off  lease  and 
expect  to  purchase  10  currently  leased  CRJ-700 
aircraft  in  the  first  part  of  2019.  We  also  refi-
nanced over $91 million of high-cost debt, primar-
ily  associated  with  spare  engine  purchases,  at  a 
much lower rate.  

Crewmembers are a critical part of our operation, 
and  in  2018  our  recruitment  team  gave  pilots  a 
number of new reasons why Mesa is a great com-
pany to fly with. In March we announced a Career 
Path Program with United Airlines, providing Mesa 
pilots  a  seamless  transition  to  the  mainline  carri-
er;  the  cadet  program  grew  to  include  26  flight 
schools  and  universities;  our  new  Rotor  Transition 
Program assists helicopter pilots in transitioning to 
the airlines. 

Looking ahead

Performance is the cornerstone of our business, 
and as we build on our strong foundation we will 
focus on continuous improvement in all areas – 
safety, reliability, and customer satisfaction. This is 
a company-wide effort and will be our top prior-
ity. 

In 2019 we will work to strengthen and extend 
our relationships with our current codeshare part-
ners while also exploring new opportunities for 
expansion, including additional partnerships and 
potential opportunities in air cargo. We believe 
our business model is particularly suited to enter 
the growing cargo sector.  

We would like to thank again our airline partners, 
American Airlines and United Airlines, our finan-
cial partners, and our vendors for their support 
while we operated as a private company. Lastly, 
I want to recognize the efforts of all of our 3,500 
employees. Each day these hard working profes-
sionals keep our airline running, our passengers 
safe, and our company moving forward. Without 
their dedication to our operation, we would not be 
where we are today. 

Sincerely,

Jonathan Ornstein 
Chairman and Chief Executive Officer

PART I

ITEM 1.  BUSINESS

General

Mesa  Airlines  is  a  regional  air  carrier  providing  scheduled  passenger  service  to  110  cities  in  39  states,  the  District  of 
Columbia, Canada, Mexico, Cuba and the Bahamas. 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, 2018, we operated a fleet of 145 aircraft with approximately 730 daily departures. We operate 64 
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, 2018, 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 2018, 2017 and 2016 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, 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  fourth  largest 
regional airline in the United States in 2017, as measured by passenger enplanements, and our flights accounted for 
approximately 8.8% 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 2017 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 Competitive Strengths

We believe that our primary strengths are:

Low-Cost  Operator. We  believe  that  we  are  among  the  lowest  cost  operators  of  regional  jet  service  in  the  United 
States. There are several key elements that contribute to our cost efficiencies:

(cid:3)

(cid:3)

(cid:3)

Efficient Fleet Composition. We exclusively operate large regional aircraft with 70+ passenger seats on a single 
FAA  certificate.  Operating  large  regional  aircraft  allows  us  to  enjoy  unit  cost  advantages  over  smaller  regional 
aircraft. Larger regional aircraft require less fuel and crew resources per passenger carried, and may also have 
maintenance cost efficiencies.

Cost  Effective,  Long-Term  Collective  Bargaining  Agreements. Our  pilots  and  flight  attendants  ratified  new  four-
year collective bargaining agreements effective as of July 13, 2017 and October 1, 2017, respectively, which are 
among the longest in the regional airline industry and include labor rate structures through 2023 for our pilots and 
2022  for  our  flight  attendants.  We  believe  that  our  collective  bargaining  agreements  and  favorable  labor 
relationships are critical for pilot retention and will provide more predictable labor costs into 2023. 

Low Corporate Overhead. Our general and administrative expenses per block hour have decreased by more than 
32% over the five-year period ended September 30, 2018. We have significantly reduced our overhead costs by 
operating  with  a  modest  administrative  and  corporate  team,  offering  cost-effective  benefit  programs  and 
implementing automated solutions to improve efficiency.

(cid:3)

Competitive  Procurement  of  Certain  Operating  Functions. We  have  long-term  maintenance  agreements  with 
expirations  extending  from  December  2020  to  December  2027  with  AAR  Aircraft  Services,  Inc.  ("AAR"),  GE 
Engine  Services,  LLC.  ("GE"),  StandardAero  Limited  ("StandardAero"),  Aviall  Services,  Inc.  ("Aviall")  and 
Bombardier  Aerospace  ("Bombardier"),  respectively,  to  provide  parts  procurement,  inventory  and  engine, 
airframe  and  component  overhaul  services.  We  expect  that  our  long-term  agreements  with  these  and  other 
strategic  vendors  will  provide  predictable  high-quality  and  cost-effective  solutions  for  most  maintenance 
categories over the next several years. 

Recruitment and Retention. We believe that we are well positioned to attract and retain qualified pilot candidates. 

We believe our recent success in pilot recruiting will continue with the introduction of our Career Path Program ("CPP") 
with United. In addition to offering competitive compensation, bonuses and benefits, we believe the following elements 
contribute to our recruiting advantage:

(cid:3)

Career  Path  Program. In  March  2018  we  announced  our  CPP  with  United,  which  is  designed  to  provide  our 
qualified current and future pilots a path to employment as a pilot at United. We believe that our CPP will help us 
continue  to  attract  qualified  pilots,  manage  natural  attrition  and  further  strengthen  our  decades-long  relationship 
with United.

(cid:3) Modern,  Large-Gauged  Regional  Jets.  We  exclusively  operate  large  regional  aircraft  with  advanced  flight  deck 
avionics. We believe that pilot candidates prefer advanced flight deck avionics because they are similar to those 
found in the larger commercial aircraft types flown by major airlines.

(cid:3) Opportunities  for  Advancement. We  believe  that  our  career  progression  is  among  the  most  attractive  in  the 
regional  airline  industry.  During  fiscal  2018,  our  pilots  had  the  opportunity  to  be  promoted  from  first  officer  to 
captain in as little as 12 months.

(cid:3)

(cid:3)

Stable  Labor  Relations. Throughout  our  long  operating  history,  we  believe  that  we  have  had  constructive 
relationships with our employees and their labor representatives. We have never been the subject of a labor strike 
or labor action that impacted our operations.

Enthusiastic  and  Supportive  Culture. Our  "pilots  helping  pilots"  philosophy  helps  us  attract,  retain  and  inspire 
our next generation of pilots. Our team-oriented culture, as demonstrated by the mentorship of our senior pilots, is 
both encouraged and expected. We strive to create an environment for our personnel where open communication 
is customary and where we celebrate our successes together.

Stable,  Long-Term  Revenue-Guarantee  Capacity  Purchase  Agreements. We  have  long-term  capacity  purchase 
agreements with American and United that extend beyond 2020 for 94 of our 144 aircraft in scheduled service (with 34 
aircraft expiring between June and December 2019 and 16 aircraft expiring between January and August 2020, if not 
extended prior to contract expiration). Both of our capacity purchase agreements are "capacity purchase," rather than 
revenue sharing arrangements. This contractual structure provides us with a predictable revenue stream and allows us 
to increase our profit margin to the extent that we are able to lower our operating costs below the costs anticipated by 
the  agreements.  In  addition,  we  are  not  exposed  to  price  fluctuations  for  fuel,  certain  insurance  expenses,  ground 
operations  or  landing  fees  as  those  costs  are  either  reimbursed  under  our  capacity  purchase  agreements  or  paid 
directly to suppliers by our major airline partners.

Fleet  Exclusively  Comprised  of  Large,  Efficient  Regional  Jets. We  exclusively  operate  large  regional  aircraft  with 
70+  passenger  seats.  These  aircraft  are  the  highest  in  demand  across  the  regional  airline  industry  and  provide  us 
with best-in-class operating  efficiencies,  providing  our  major  airline  partners  greater  flexibility  in  route  structuring  and 
increased passenger revenues. As of September 30, 2018, we had 145 aircraft (owned and leased) consisting of the 
following:

In  February  2018,  we  mutually  agreed  with  United  to  temporarily  remove  two  aircraft  from  service  under  our 
United Capacity Purchase Agreement. These aircraft were placed back in service in July 2018 and are reflected 
here.
CRJ-200 is an operational spare not assigned for service under our capacity purchase agreements.

Longstanding  Relationships  with  American  and  United. We  began  flying  for  American,  through  its  predecessor 
entities,  in  1992  and  United  in  1991.  Since  2013,  we  have  added  26  aircraft  to  our  American  Capacity  Purchase 
Agreement and 60 aircraft to our United Capacity Purchase Agreement.

Strong  Recent  Record  of  Operational  Performance. We  were  ranked  the  number  one  regional  airline  for  on-time 
performance  by  DOT  Air  Travel  Consumer  Report  for  three  of  the  first  nine  months  of  2018,  which  was  equal  to  or 
better  than  any  other  regional  airline.  In  addition,  we  believe  that  we  were  the  number  one  regional  airline  for  on-
time performance  in  2016  and  2017  based  on  a  comparison  of  our  internal  data  to  publicly  available  DOT  data  for 
reporting  airlines.  Under  our  capacity  purchase  agreements,  we  may  receive  financial  incentives  or  incur  penalties 
based  upon  our  operational  performance,  including  controllable on-time departures  and  controllable  completion 
percentages.

Experienced, Long-Tenured Management Team. Our senior management team has extensive operating experience 
in  the  regional  airline  industry.  Our  Chief  Executive  Officer  and  President/Chief  Financial  Officer  have  served  us  in 
senior  officer  positions  since  1998,  and  our  management  team  has  helped  us  navigate  through  and  emerge 
successfully from bankruptcy in early 2011. 

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.

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. We completed our initial public offering ("IPO") in August 2018. We intend to use a portion of the IPO 
proceeds  to  purchase  some  of  our  leased  aircraft.  The  purchase  of  these  leased  aircraft  will  allow  us  to  lower  our 
operating  costs  and  avoid  lease-related  use  restrictions  and  return  conditions.  We  also  intend  to  use  a  portion  of  the 
IPO proceeds to repay certain higher interest debt and refinance the balance at a reduced interest rate.

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, 
2018, we had 18 aircraft with leases extending past the term of their corresponding capacity purchase agreements with 
an  aggregate  exposure  of  less  than  $33.0 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.

The following table lists the aircraft we own and lease as of September 30, 2018:

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.

Route Network

As  of  September 30,  2018,  we  served  110 airports  throughout  the  United  States,  Canada,  Mexico,  Cuba  and  the 
Bahamas. Our flight schedules are structured to facilitate the connection of our passengers with the flights of our major 
airline partners at their hub airports and to maximize local and connecting service to other carriers. Under our American 
and  United  Capacity  Purchase  Agreements,  market  selection,  pricing  and  yield  management  functions  are  performed 
by our respective major airline partners.

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.

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, 2018 and 2017, respectively:

American Capacity Purchase Agreement

As  of  September 30,  2018,  we  operated  64 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, 2018 and 2017, we issued credits 
of approximately $5.2 million and $6.0 million, respectively, under our American Capacity 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)  with  respect  to 
certain  aircraft  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)

(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;

If  our  controllable  flight  completion  factor  falls  below  certain  levels  for  a  specified  period  of  time,  subject  to  our 
right to cure; or

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, 2018, American held 10.5% of our outstanding common stock (or 7.2% on a fully-diluted basis), 
which  interest  American  received  in  exchange  for  an  extension  of  our  capacity  purchase  agreement  during  our 
bankruptcy proceeding. 

United Capacity Purchase Agreement

As  of  September 30,  2018,  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 has purchased 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  under  our  United  Capacity  Purchase  Agreement.  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.

Our  United  Capacity  Purchase  Agreement  expires  between  June  and  December  2019  with  respect  to  34 CRJ-
700 and E-175 aircraft,  between  January  and  August  2020  with  respect  to  16  E-175  aircraft,  and  between  2021  and 
2028  with  respect  to  30  of  our  E-175  aircraft,  subject  to  United's  early  termination  rights  and  right  to  extend  (on  the 
same terms) for a total of four additional two-year terms. We intend to work with United to extend our United Capacity 
Purchase  Agreement  with  respect  to  these  aircraft,  but  there  can  be  no  assurance  that  we  will  be  able  to  extend  the 
agreement at acceptable rates, on acceptable terms, or at all.

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

A key element of our business and low-cost strategy is the responsible outsourcing of certain aircraft maintenance and 
other operating functions. We use competitive bidding among qualified vendors to procure these services on the best 
possible terms. In March 2014, August 2015 and January 2017, we entered into 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 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, 2018, $51.0 million of parts inventory was consigned to us 
by AAR under long-term contracts that is not reflected on our balance sheet.

In  July  2012,  we  entered  into  a  heavy  check  maintenance  contract  with  Bombardier,  to  perform  heavy  check 
maintenance on our CRJ-700 and CRJ-900 aircraft, which extends through November 2020.

In July 2013, we entered into an engine maintenance contract with GE to perform heavy maintenance on certain CRJ-
700 and CRJ-900  engines  based  on  a  fixed  pricing  schedule.  The  pricing  may  escalate  annually  in  accordance  with 
GE's spare parts catalog for engines. The engine maintenance contract extends through 2024.

In  2014,  we  entered  into  a ten-year contract  with  Aviall  to  provide  maintenance  and  repair  services  on  the  wheels, 
brakes and tires of our CRJ-700 and CRJ-900 aircraft. Under the agreement, we pay Aviall a fixed "cost per landing" 
fee for all landings of our aircraft during the term of the agreement, which fee is subject to annual adjustment based on 
increases  in  the  cost  of  labor  and  component  parts.  As  of  September 30,  2018,  $7.1 million  of  parts  inventory  was 
consigned to us by Aviall under long-term contracts that is not reflected on our balance sheet.

We  entered  into  an  engine  maintenance  contract  with  StandardAero,  which  became  effective  on  June 1,  2015,  to 
perform heavy maintenance on certain CRJ-700 and CRJ-900 engines based on a fixed pricing schedule. The pricing 
may  escalate  annually  in  accordance  with  GE's  spare  parts  catalog  for  engines.  The  engine  maintenance  contract 
extends through 2020.

Apart  from  our  outsourcing  of  certain  maintenance  functions,  we  have  a  FAA  mandated  and  approved  maintenance 
program. Our maintenance technicians undergo extensive initial and recurrent training. 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.

Line  maintenance  consists  of  routine  daily  and  weekly  scheduled  maintenance  checks  on  our  aircraft.  We  categorize 
our line maintenance into four stations and each line maintenance station is categorized by the scope and complexity of 
work performed. Line maintenance is performed in Dallas, Houston, Phoenix and Washington, D.C. 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.

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,  2018,  we  employed  approximately  3,412  employees,  consisting  of  1,358  pilots  or  pilot  recruits, 
1,287 flight attendants, 55 flight dispatchers, 426 mechanics and 286 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. During fiscal 2017, we experienced higher than average turnover as a result of 
pilot wage increases at certain other regional air carriers and expanded hiring by major carriers. 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, 

10

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.

As of September 30, 2018, approximately 77.5% 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.

On July 13, 2017, our pilots ratified a new four-year collective bargaining agreement.
On October 1, 2017, our flight attendants also ratified a new four-year collective bargaining agreement.

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.

Facilities

In  addition  to  aircraft,  we  have  office  and  maintenance  facilities  to  support  our  operations.  Each  of  our  facilities  are

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, 2018, there were outstanding warrants to purchase 10,614,990 shares of our common 
stock,  with  an  exercise  price  of  $0.004  per  share.    There  were  250,000  warrants  to  purchase  shares  of  our  common 
stock with an exercise price of $3.20 per share that were terminated in June 2018. 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.

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.

ITEM 1A.  RISK FACTORS 

Investing in our common stock involves a high degree of risk. 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. 

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.  For  our  fiscal  year  ended 
September 30, 2018, we issued credits of approximately $5.2 million under our American Capacity Agreement. 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. 

14

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  54%  and  56%  of  our  total  revenue  for  our  fiscal  years  ended  September 30, 
2018  and  2017,  respectively.  United  accounted  for  approximately  46%  and  44%  of  our  revenue  for  our  fiscal  years 
ended  September 30,  2018  and  2017,  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. 

Our United Capacity Purchase Agreement expires between June and December 2019 with respect to 20 CRJ-700 and 
14 E-175 aircraft,  between  January  and  August  2020  with  respect  to  16  E-175  aircraft,  and  between  2022  and  2028 
with  respect  to  30  of  our  E-175  aircraft.  We  are  currently  in  negotiations  with  United  with  respect  to  the  20  CRJ-700 
aircraft expiring between August and December 2019. We cannot predict the outcome of these negotiations and there 
can  be  no  assurance  that  we  will  be  able  to  extend  these  aircraft  at  acceptable  rates,  on  acceptable  terms,  or  at  all. 
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. 

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. 

15

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. 

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. 

16

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, 2018, we had 
approximately $930.2 million in total long-term debt including $9.7 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, 
2018,  2017  and  2016,  our  principal  debt  service  payments  totaled  $222.2 million,  $153.0  million  and  $75.5  million, 
respectively,  and  our  principal  aircraft  lease  payments  totaled  approximately  $64.6  million,  $107.0 million  and  $70.0 
million, respectively. 

We have significant lease obligations with respect to our aircraft, which aggregated to approximately $207.9 million and 
$316.1 million at September 30, 2018 and 2017, respectively. At September 30, 2018, we had 28 aircraft under lease 
(excluding aircraft leased from United), with an average remaining term of 5.5 years. As of September 30, 2018, future 
minimum lease payments due under all long-term operating leases were approximately $218.7 million and debt service 
obligations were $1,130.5 million, respectively, including capital lease obligations. 

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; 

17

(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. 

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, 2018, we had approximately $1,250.8 million of property and equipment and related assets, net of 
accumulated depreciation, of which, $1,048.4 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,  2018, 
approximately  $42.6 million,  or  7.0%,  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. 

18

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,  2018,  approximately  77.5%  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. 

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 less than $33.0 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 and may be materially different than our projections. 
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. 

19

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. 

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  2.9,  12.0  and  14.7  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 airccraft. 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. 

20

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. 

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,  2018,  we  had  aggregate  federal  and  state  net  operating  loss  carryforwards  of  approximately 
$415.1 million  and  $199.6 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  which  had  a  full  valuation  allowance.  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.  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. 

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. 

24

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,  2018,  we  had  outstanding  warrants  to  purchase  an  aggregate  of  10,614,990  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. 

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 

25

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, 2018, we had outstanding warrants to purchase 10,614,990 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. 

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)

(cid:3)

(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; 

we  may  present  reduced  disclosure  regarding  executive  compensation  in  our  periodic  reports  and  proxy 
statements; and 

we  are  not  required  to  hold  nonbinding  advisory  shareholder  votes  on  executive  compensation  or  golden 
parachute arrangements. 

26

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. 

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 will be 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 ending September 30, 
2019.  This  assessment  includes  disclosure  of  any  material  weaknesses  identified  by  our  management  in  our  internal 
control over financial reporting, as well as a statement that our independent registered public accounting firm has issued 
an  opinion  on  our  internal  control  over  financial  reporting,  provided  that  our  independent  registered  public  accounting 
firm will not be 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  will  be  required  to  disclose  changes  made  in  our  internal  control  and 
27

procedures  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. We have begun the costly and challenging process of compiling the system and processing documentation 
necessary  to  perform  the  evaluation  needed  to  comply  with  Section 404,  and  we  may  not  be  able  to  complete  our 
evaluation, testing, and any required remediation in a timely fashion or at all.

In future periods, if we fail to achieve and maintain an effective internal control environment, we could suffer material 
misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors 
to lose confidence in our reported financial information. Additionally, ineffective internal control over financial reporting 
could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the 
regulatory investigations, civil or criminal sanctions and litigation, any of which would have a material adverse effect on 
our business, results of operations and financial condition.

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, 2018, we operated 64 CRJ-900 aircraft under our American Capacity Purchase 
Agreement. 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) 
with respect to certain aircraft 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.

CRJ-700s  –  As  of  September  30,  2018,  we  operated  20  CRJ-700  aircraft  under  our  United  Capacity  Purchase 
Agreement. Subject to certain early termination rights, the capacity purchase agreement for each of the 20 CRJ-
700  aircraft  expires  between  August  and  December  2019.  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.   

E-175s  –  As  of  September  30,  2018,  we  operated  60  E-175  aircraft  under  our  United  Capacity  Purchase 
Agreement. Our United Capacity Purchase Agreement expires between June 2019 and August 2020 with respect 
to 30 of the E-175 aircraft (owned by United), 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 two-year 
terms  (for  a  maximum  of  eight  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. During our fiscal 2017, we agreed with United to expand our United Capacity Purchase 
Agreement to include, subject to early termination rights, 12 additional E-175 aircraft (purchased by United), the 
last  of  which  entered  service  in  January  2018.  These  additional  E-175  aircraft  have  a  five-year  term  under  our 
United Capacity Purchase Agreement, subject to United's right to extend for up to four additional two-year terms 
(for  a  maximum  of  eight  additional  years).  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.

CRJ-200s – As of September 30, 2018, we operated one CRJ-200 aircraft as an operational spare.

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, 2018 we had 66 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.

Stock Split

On  August 8,  2018  we  filed  a  Second  Amended  and  Restated  Articles  of  Incorporation,  which,  among  other  things: 
(i) effected  a  2.5-for-1  stock  split  of  our  common  stock;  and  (ii) increased  the  authorized  number  of  shares  of  our 
common  and  preferred  stock  to  125,000,000  and  5,000,000,  respectively.  All  references  to  share  and  per  share 
amounts  in  the  consolidated  financial  statements  have  been  retrospectively  revised  to  reflect  the  stock  split  and 
increase in authorized shares.

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 2019 Annual Meeting of Shareholders ("2019 Proxy Statement") to be filed with the 
SEC within 120 days of our fiscal year ended September 30, 2018.

Our  operations  data  for  our  fiscal  years  ended  September  30,  2014  include  results  from  our  historical  go! 
operations. We operated go! as an inter-island air carrier in Hawaii from 2006 to 2014. 
See Note 9 to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for an 
explanation of the method used to calculate the basic and diluted earnings per share.

(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. 

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 

32

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:

Our financial results reflect a one-time, non-cash increase in accrued compensation of approximately $13.5 million 
related  to  an  increase  in  the  value  of  our  stock  appreciation  rights  ("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. 
Our  financial  results  include  a  one-time,  non-cash  lease  termination  expense  of  $15.1  million  related  to  our 
acquisition of 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"),  for  $76.5 
million.

ITEM  7.  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  110  cities  in  39  states,  the  District  of 
Columbia, Canada, Mexico, Cuba and the Bahamas.  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, 2018, we operated a fleet of 145 aircraft with approximately 730 daily departures. We operate 64 
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, 2018, 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 2018, 2017 and 2016 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. 

2018 Financial Highlights

For  our  fiscal  year  ended  September  30,  2018,  we  had  total  operating  revenues  of  $681.6  million,  a  5.9%  increase, 
compared  to  $643.6  million  for  our  fiscal  year  ended  September  30,  2017.    Net  income  for  our  fiscal  year  ended 
September 30, 2018 was $33.3 million, or $1.32 per diluted share, compared to net income of $32.8 million, or $1.40 
per diluted share, for our fiscal year ended September 30, 2017.  Our fiscal 2018 results include a $22.0 million benefit 
related to the revaluation of our net deferred tax liability and other tax liabilities as a result of the Tax Cuts and Jobs Act 
(the "Tax Act") that was enacted into law in December 2017.  

We  recorded  two  one-time  non-cash  adjustments  in  fiscal  2018.  The  first  was  $15.1  million  of  lease  termination 
expense related to our acquisition of 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"). 
The second adjustment resulted from an increase in the value of our stock appreciation rights ("SARs") driven by an 
increase in the fair value of our common stock and a change in accounting methodology from the intrinsic value method 
to  fair  value  method.  This  second  non-cash  adjustment  resulted  in  a  general  and  administrative  expense  of  $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 during fiscal 2018.

During our 2018 fiscal year, we added five E175 aircraft to our fleet, increasing our fleet size to 145 aircraft. In addition, 
we increased our completed block hours by 15,891, or 4.0%, compared to our fiscal year ended September 30, 2017.

Initial Public Offering

On August 14, 2018, we completed our IPO in which we issued and sold 9,630,000 shares of our common stock at a 
public offering price of $12.00 per share. On September 11, 2018, we sold an additional 1,344,500 shares at a price of 
$12.00  per  share  pursuant  to  a  partial  exercise  of  the  underwriters'  option  to  purchase  additional  shares.  Of  the 
1,344,500 shares sold pursuant to the option, 723,985 were purchased from us and the remaining 620,515 shares were 
purchased  directly  from  selling  shareholders.    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 $3.8 million in offering costs.

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.

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 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, 2018, approximately 77.5% 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, 2018, $58.1 million of 
parts inventory was consigned to us by AAR and Aviall under long-term contracts that is not reflected on our balance 
sheet.

37

The  average  age  of  our E-175, CRJ-900 and CRJ-700 type  aircraft  is  approximately  2.9,  12.0  and  14.7  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.  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, 2018, we had 70 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" 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.

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. 

38

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 that we equally recognize as 
both a revenue and expense. 

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.  As  of  September 30,  2018,  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  United-owned  E-175  aircraft,  as  well  as 
maintenance-related  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. 

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 

Our other (expense) income, net consists of the following items:

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

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

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

Results of Operations 

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  in  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. 

39

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.

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.

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. 

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.

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  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. 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. 

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 the 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  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  remeasurement  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. 

The income tax provision for our fiscal year ended September 30, 2017 resulted in an effective tax rate of 38.9%, which 
differs  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  the  Tax  Act  into  law.  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  our  fiscal  year  ended  September 30,  2018,  and  21%  for  our  fiscal  years  ending  September 30,  2019  and 
forward.  The  decrease  in  federal  statutory  rate  resulted  in  a  net  tax  benefit  due  to  the  remeasurement  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. 

42

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; a limit on net interest expense deductions of 30% of earnings before interest, taxes, depreciation, and 
amortization through 2021 and of earnings before interest and taxes thereafter; and a limit on the net operating losses 
incurred in tax years beginning after December 31, 2017 that taxpayers may use to offset their taxable income of up to 
80% in a given year. 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  $199.6  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.

Comparison of our Fiscal Years Ended September 30, 2017 and 2016 

We had operating income of $100.3 million in our fiscal year ended September 30, 2017 compared to operating income 
of  $56.8 million  in  our  fiscal  year  ended  September  30,  2016.  In  our  fiscal  2017,  we  had  net  income  of  $32.8 million 
compared to net income of $14.9 million in our fiscal 2016. Our operating results for our fiscal year ended September 
30,  2017  reflected  an  increase  in  contract  revenue  primarily  related  to  the  addition  of  seven  E-175  aircraft  under  our 
United Capacity Purchase Agreement, along with a reduction in maintenance expense due to the timing of significant 
maintenance  events,  including  engine  overhauls,  which  occurred  less  frequently  in  our  fiscal  2017  than  in  our  fiscal 
2016. 

Our fiscal 2017 financial results reflected the execution of our strategy to add additional aircraft pursuant to our capacity 
purchase  agreements  while  maintaining  cost  discipline.  In  our  fiscal  2017,  we  were  able  to  increase  our  block  hour 
compensation from our major airline partners in addition to adding seven E-175 aircraft to our fleet. We also ratified a 
new  four-year  collective  bargaining  agreement,  which  allowed  us  to  maintain  competitive  labor  costs,  which  are 
consistently among our largest expenses.

Total  operating  revenue  increased  by  $55.7 million,  or  9.5%,  during  our  fiscal  year  ended  September  30,  2017,  as 
compared to our fiscal year ended September 30, 2016. Contract revenue increased by $49.3 million, or 8.7%, primarily 
due  to  the  addition  of  seven  new  E-175  aircraft  to  our  fleet  in  our  fiscal  2017  and  higher  block  hour  compensation, 
primarily  driven  by  the  aircraft  added  to  our  fleet.  In  addition,  we  added  16  E-175  aircraft  to  our  fleet  between  the 
second and fourth quarters of our fiscal 2016, which more directly impacted our contract revenue during our fiscal 2017. 
Our block hours flown during our fiscal 2017 increased 7.2% over our fiscal 2016, primarily due to the additional E-175 
aircraft. Our pass-through and other revenue increased during our fiscal 2017 by $6.4 million, or 34.7%, primarily due to 
pass-through maintenance costs related to our E-175 aircraft fleet.

Flight  Operations.  In  our  fiscal  2017  year,  flight  operations  expense  increased  by  $14.1 million,  or  10.0%,  to 
$155.5 million,  from  $141.4 million  during  our  fiscal  2016.  This  increase  was  primarily  driven  by  $11.5 million  in 
additional  wages,  taxes  and  benefits  under  our  new  collective  bargaining  agreements,  and  an  increase  in  our  block 
hours flown. 

Fuel. Fuel expense remained relatively consistent during our fiscal year ended September 30, 2017, compared to our 
fiscal year ended September 30, 2016. All fuel costs related to flying under our capacity purchase agreements during 
our 2017 and 2016 fiscal years were directly paid to suppliers by our major airline partners. 

Maintenance. In our 2017 fiscal year, aircraft maintenance costs decreased by $14.4 million, or 6.4%, during our fiscal 
year ended September 30, 2017, compared to our fiscal year ended September 30, 2016. This decrease was primarily 
driven  by  a  $26.9 million  decrease  in  engine  overhaul  expense  due  to  the  timing  of  significant  maintenance  events, 
including engine overhauls, which occurred less frequently in our fiscal 2017 than in our fiscal 2016. That decrease was 
partially offset by an increase of $9.5 million in aircraft maintenance costs related to performing more "C" maintenance 
checks  ("C-checks")  during  our  fiscal  2017  than  during  our  fiscal  2016.  Total  pass-through  maintenance  expense 
reimbursed  by  our  major  airline  partners  increased  by  $7.4 million  during  our  fiscal  year  ended  September  30,  2017 
compared to our fiscal year ended September 30, 2016.

Aircraft  Rent.  In  our  fiscal  2017,  aircraft  rent  expense  increased  by  $0.9 million,  or  1.3%,  to  $72.6 million  from 
$71.6 million in our fiscal 2016. This increase was attributable to a $1.5 million manufacturer lease credit that expired in 
December 2015, and was partially offset by a $0.6 million increase in engine rent. 

44

Aircraft  and  Traffic  Servicing.  In  our  fiscal  2017,  aircraft  and  traffic  servicing  expense  decreased  by  $0.3 million,  or 
6.6%, to $3.7 million from $3.9 million in our fiscal 2016. The decrease is primarily due to a reduction in interrupted trip 
expenses and international navigation fees compared to our fiscal 2016. For our fiscal years ended September 30, 2017 
and  2016,  46.5%  and  42.6%  respectively,  of  our  aircraft  and  traffic  servicing  expense  were  reimbursed  by  our  major 
airline partners. 

General and Administrative. General and administrative expense decreased $3.2 million, or 7.6%, during our fiscal year 
ended  September  30,  2017,  compared  to  our  fiscal  year  ended  September  30,  2016.    This  decrease  was  primarily 
related  to  a  decrease  in  insurance  costs  of  $1.1 million  and  a  decrease  in  wages  and  employee  related  expense  of 
$2.1 million. 

Depreciation  and  Amortization.  In  our  2017  fiscal  year,  depreciation  and  amortization  expense  increased  by 
$15.0 million, or 32.7% during our fiscal year ended September 30, 2017, compared to our fiscal year ended September 
30, 2016. This increase was due to an increase of $9.8 million in aircraft depreciation due to placing 16 E-175 aircraft 
into service during 2016, which resulted in partial depreciation in our fiscal 2016. This increase was also attributable to 
an  increase  of  $4.4 million  in  spare  engine  depreciation  due  to  purchasing  additional  spare  engines  during  our  fiscal 
2017. 

Other Expense 

Other  expense  increased  by  $14.7 million,  during  our  fiscal  year  ended  September  30,  2017,  compared  to  our  fiscal 
year ended September 30, 2016 due to an increase in aircraft interest expense of $7.3 million related to the financing of 
16 E-175 aircraft between the second and fourth quarter of our fiscal 2016, along with an increase in interest expense of 
$5.5 million related to the financing of 20 spare engines. Our expenses related to debt financing amortization were also 
higher  during  our  fiscal  year  ended  September  30,  2017  by  $0.8 million,  as  a  result  of  legal  and  commitment  fees 
incurred in connection with the financing of aircraft engines and the acquisition of E-175 aircraft. 

Income Taxes 

In our fiscal year ended September 2017, our effective tax rate was 38.9%, compared to 40.0% in our fiscal 2016. Our 
tax rate can vary depending on 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  $20.9 million  and  an  income  tax  provision  of  $9.9 million  for  our  fiscal  years 
ended September 30, 2017 and 2016, respectively. 

This income tax provision for our fiscal year ended September 30, 2017 resulted 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. 

This income tax provision for our fiscal year ended September 30, 2016 resulted in an effective tax rate of 40.0%, 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. 

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. 

See Note 11: "Income Taxes" in the notes to the consolidated financial statements included elsewhere in this Annual 
Report on Form 10-K. 

Non-GAAP Measures and Reconciliations

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 and lease termination costs. 

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 and lease termination costs. 

45

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.

Our financial results reflect a one-time, non-cash increase in accrued compensation of approximately $13.5 million 
related  to  an  increase  in  the  value  of  our  stock  appreciation  rights  ("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. 

Our  financial  results  include  a  one-time,  non-cash  lease  termination  expense  of  $15.1 million  related  to  our 
acquisition of 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"),  for 
$76.5 million.

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  names  therein  (the  "CIT  Lenders")  have  committed  to  lend  to  Mesa 
Airlines 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, 2019. 

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. 

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,  2018,  we  had  $123.2 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 estimated 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, 2018, we 
paid  $118.0 million  in  capital  expenditures  primarily  related  to  the  purchase  of  nine  CRJ-900  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  1.2%  to  1.5%  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, 2018, our principal sources of liquidity were cash and cash equivalents and marketable securities 
of $123.2 million. In addition, we had restricted cash of $3.8 million as of September 30, 2018. 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, 2018, we also had $803.8 million in secured indebtedness incurred in 
connection  with  our  financing  of  74  total  aircraft.  Our  primary  uses  of  liquidity  are  capital  expenditures,  aircraft  pre-
delivery  payments  and  debt  repayments.  As  of  September 30,  2018,  we  had  $154.0 million  of  short-term  debt, 
excluding capital leases, and $766.5 million of long-term debt excluding capital leases.

Sources  of  cash  for  our  fiscal  year  ended  September 30,  2018  were  primarily  cash  flows  from  operations  of 
$118.9 million as well as IPO proceeds of $111.7 million. The positive cash flow from operations was driven by receipts 
from performance under our capacity purchase agreements. 

Restricted Cash 

As of September 30, 2018, we had $3.8 million in restricted cash. We have an agreement with a financial institution for 
a $6.0 million letter of credit facility and to issue letters of credit for landing fees, worker's compensation insurance and 
other  business  needs.  Pursuant  to  the  agreement,  $3.8 million  of  outstanding  letters  of  credit  are  required  to  be 
collateralized by amounts on deposit.

During  our  fiscal  year  ended  September 30,  2018,  our  cash  flow  provided  by  operating  activities  of  $118.9 million 
reflected  our  growth  and  execution  of  our  strategic  initiatives.  We  had  net  income  of  $33.3 million  adjusted  for  the 
following  significant  non-cash  items:  depreciation  and  amortization  of  $65.0 million,  amortization  of  stock-based 
compensation of $12.9 million, deferred income taxes of $(17.9) million, amortization of unfavorable lease liabilities and 
deferred credits of $(11.0) million, amortization of debt financing costs and accretion of interest on non-interest bearing 
subordinated notes of $4.6 million and lease termination expense of $15.1 million. We had net change of $16.4 million 
within  other  net  operating  assets  and  liabilities  largely  driven  by  accrued  compensation  liability  and  other  accrued 
liabilities during our fiscal year ended September 30, 2018. 

During our fiscal year ended September 30, 2017, our cash flow provided by operating activities of $74.7 million reflects 
our  growth  and  execution  of  our  strategic  initiatives.  We  had  net  income  of  $32.8 million  adjusted  for  the  following 
significant non-cash items: depreciation and amortization of $61.0 million, amortization of stock-based compensation of 
$1.3 million, deferred income taxes of $20.5 million, amortization of unfavorable lease liabilities and deferred credits of 
$(10.6) million and amortization of debt financing costs and accretion of interest on non-interest bearing subordinated 
notes of $2.7 million. We had net outflows of $33.9 million within other net operating assets and liabilities largely driven 
by aircraft lease payments during our fiscal year ended September 30, 2017. 

During  our  fiscal  year  ended  September 30,  2016,  our  cash  flow  provided  by  operating  activities  of  $104.5 million 
reflects  our  growth  and  execution  of  our  strategic  initiatives.  We  had  net  income  of  $14.9 million  adjusted  for  the 
following  significant  non-cash  items:  depreciation  and  amortization  of  $46.0 million,  amortization  of  stock-based 
compensation  of  $1.5 million,  deferred  income  taxes  of  $9.5 million,  amortization  of  unfavorable  lease  liabilities  and 
deferred  credits  of  $(9.6)  million  and  amortization  of  debt  financing  costs  and  accretion  of  interest  on  non-interest 
bearing subordinated notes of $2.0 million. We had a net increase of $39.1 million within other net operating assets and 
liabilities largely driven by timing of payments made on aircraft leases, engine repair work and other payables during our 
fiscal year ended September 30, 2016.

Net Cash Flows Used In Investing Activities 

During our fiscal year ended September 30, 2018, our net cash flow used in investing activities was $(138.8) million. We

invested $84.5 million in 15 spare engines and aircraft improvements, offset partially by returns of equipment deposits. 

During our fiscal year ended September 30, 2016, our net cash flow used in investing activities was $(491.1) million. We 
invested $490.1 million in 18 E-175 aircraft, four spare engines and aircraft improvements.

During our fiscal year ended September 30, 2018, our net cash flow provided by financing activities was $66.4 million. 
We  received  $187.7  million  in  proceeds  from  long-term  debt  primarily  related  to  purchasing  nine  aircraft,  refinancing

Commitments and Contractual Obligations 

As  of  September 30,  2018,  we  had  $1,353.7  million  of  long-term  debt  (including  principal  and  projected  interest

As of September 30, 2018, we had variable rate notes representing 65.2% of our total long-term debt.  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, 2018, we had 
28 aircraft on lease (excluding aircraft leased from United) with remaining lease terms up to 5.5 years. Future minimum 
lease payments due under all long-term operating leases were approximately $218.7 million as of September 30, 2018.

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. 

49

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, 2018, 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  17  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 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,  2018 
without  the  prior  written  consent  of  the  GECAS  Lease  Facility  parties.  As  of  September 30,  2018,  we  were  in 
compliance with these covenants. 

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  $9.7  million  on  our  balance  sheet  as  of  September 30,  2018.  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. On April 27, 2018, we entered into an amendment to the CIT Revolving Credit Facility to lower the consolidated 
interest and rental coverage ratio through the end of the term of the agreement. As of September 30, 2018, we were in 
compliance with the financial covenants under the CIT Revolving Credit Facility. The CIT Revolving Credit Facility also 
includes  customary  events  of  defaults,  including  but  not  limited  to:  (i) payment  defaults;  (ii) breach  of  covenants; 
(iii) breach of representations and warranties; (iv) cross-defaults; (v) certain bankruptcy-related defaults; (vi) change of 
control; and (vii) revocation of instructions with respect to certain controlled accounts. 

On August 14, 2018, we paid down the outstanding balance on the CIT Revolving Credit Facility of $25.7 million. The 
CIT  Revolving  Credit  Facility  matures  on  August  12,  2019.    As  of  September  30,  2018,  there  were  no  borrowings 
outstanding  under  this  facility.    Funds  available  under  the  CIT  Revolving  Credit  Facility  are  subject  to  certain 
administrative and commitment fees, and funds under the facility bear interest at LIBOR plus a margin of 4.25%

Engine Notes 

Spare  Engine  Facility.  In  December  2016,  Mesa  Airlines,  as  borrower,  Obsidian  Agency  Services,  Inc.,  as  security 
trustee,  Cortland  Capital  Market  Services  LLC,  as  administrative  agent,  and  the  lenders  party  thereto  (the  "Engine 
Financing  Lenders")  entered  into  a  credit  agreement  (the  "Spare  Engine  Facility")  pursuant  to  which  the  Engine 
Financing  Lenders  committed  to  lend  to  Mesa  Airlines  term  loans  in  the  aggregate  principal  amount  of  up  to 
approximately  $99.1 million.  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. The Spare Engine Facility contains affirmative and negative covenants that are typical in the industry 
for similar financings, including, but not limited to, covenants that, subject to exceptions described in the Spare Engine 
Facility, restrict the ability of Mesa Airlines to: 

50

(i) enter into, create, incur, assume or suffer to exist any liens; and (ii) merge, dissolve, liquidate, consolidate or sell or 
transfer  substantially  all  of  its  assets.  As  of  September 30,  2018,  we  were  in  compliance  with  these  covenants.  The 
Spare  Engine  Facility  also  includes  customary  events  of  defaults,  including,  but  not  limited  to:  (i) payment  defaults; 
(ii) breach of covenants; (iii) breach of representations and warranties; and (iii) material adverse changes. 

There  are  four  tranches  of  debt  under  the  Spare  Engine  Facility,  which  mature  between  January 2022  and  February 
2023. As of September 30, 2018, $88.2 million of borrowings were outstanding under the Spare Engine Facility. Funds 
drawn under the Spare Engine Facility bear interest at the rate of 7.25% per annum plus the greater of (a) 0.5% or (b) 
the Eurodollar rate. The facility will be repaid periodically according to amortization schedules, with the entire remaining 
outstanding  principal  balance  to  be  paid  on  the  applicable  maturity  date.  As  of  September 30,  2018,  $88.2 million  of 
borrowings were outstanding under this facility, and $91.3 million of Mesa Airlines' equipment was pledged under this 
facility.

EDC Credit Facilities. In August 2015, Mesa Airlines, as borrower, and EDC, as lender entered into a credit agreement 
(the "EDC 2015 Credit Facility") pursuant to which EDC committed to purchase notes from Mesa Airlines from time to 
time  in  the  aggregate  principal  amount  of  up  to  $11.0 million.  The  borrower's  obligations  under  the  EDC  2015  Credit 
Facility are unsecured and guaranteed by us. The EDC 2015 Credit Facility contains affirmative and negative covenants 
that are typical in the industry for similar financings, including, but not limited to, covenants that, subject to exceptions 
described  in  the  EDC  2015  Credit  Facility,  restrict  our  ability  to:  (i) merge,  dissolve,  liquidate,  consolidate  or  sell  or 
transfer substantially all of its assets; or (ii) sell assets. The EDC 2015 Credit Facility also includes customary events of 
defaults,  including,  but  not  limited  to:  (i) payment  defaults;  (ii) breach  of  covenants;  (iii) breach  of  representations  and 
warranties;  (iv) cross-defaults;  (v) certain  bankruptcy-related  defaults  of  Mesa  Airlines  or  of  specified  carriers;  and 
(vi) termination or material adverse change in the terms of any code sharing agreement. Each note matures on the date 
that  is  five  years  after  such  note  was  issued.  As  of  September 30,  2018,  $4.4 million  of  borrowings  were  outstanding 
under this facility. As of September 30, 2018, we were in compliance with the covenants described above. 

Funds drawn under the EDC 2015 Credit Facility are subject to certain arrangement and commitment fees, and funds 
drawn under the facility bear interest at (i) LIBOR plus a margin of 2.66% plus a margin benchmark of 0.41% or (ii) a 
fixed amount based on a swap rate of floating rate debt to fixed rate debt, plus a margin of 2.66% and plus a margin 
benchmark of 0.58%. Installment payments must be made on each note issued under this facility. 

In January 2016, Mesa Airlines, as borrower, and EDC, as lender, entered into a credit agreement (the "EDC January 
2016 Credit Facility") pursuant to which EDC committed to purchase notes from Mesa Airlines from time to time in the 
aggregate  principal  amount  of  up  to  $37.0 million.  The  borrower's  obligations  under  the  EDC  January  2016  Credit 
Facility are secured by the underlying equipment and guaranteed by us. The EDC January 2016 Credit Facility contains 
affirmative  and  negative  covenants  that  are  typical  in  the  industry  for  similar  financings,  including,  but  not  limited  to, 
covenants that, subject to exceptions described in the EDC January 2016 Credit Facility, restrict our ability to: (i) merge, 
dissolve,  liquidate,  consolidate  or  sell  or  transfer  substantially  all  of  our  assets;  or  (ii) sell  assets.  The  EDC  January 
2016 Credit Facility also contains a financial covenant that requires us to maintain a fixed charge coverage ratio at the 
end  of  each  fiscal  quarter  above  the  amount  specified  in  the  agreement.  As  of  September 30,  2018,  we  were  in 
compliance with these covenants. 

The  EDC  January  2016  Credit  Facility  also  includes  customary  events  of  default,  including,  but  not  limited  to: 
(i) payment  defaults;  (ii) breach  of  covenants;  (iii) breach  of  representations  and  warranties;  (iv) cross-defaults; 
(v) certain  bankruptcy-related  defaults  of  Mesa  Airlines  or  of  specified  carriers;  (vi) termination  or  material  adverse 
change  in  the  terms  of  any  code  sharing  agreement;  and  (vii) breach  or  termination  of  our  agreement  with 
StandardAero.  Each  note  matures  on  the  date  that  is  three  to  four  years  after  such  note  was  issued.  As  of 
September 30, 2018, $15.0 million of borrowings were outstanding under this facility. 

Funds drawn under the EDC January 2016 Credit Facility are subject to certain arrangement and commitment fees, and 
funds drawn under the facility bear interest at (i) LIBOR plus a margin of, initially, 2.49% plus a margin benchmark of 
0.47% or (ii) a fixed amount based on a swap rate of floating rate debt to fixed rate debt plus a margin of, initially, 2.49% 
plus a margin benchmark of 0.68%. Installment payments must be made on each note issued under this facility. 

On April 30, 2018, Mesa Airlines and EDC amended the EDC January 2016 Credit Facility to, among other things, lower 
the  required  fixed  charge  ratio  covenant  through  the  end  of  the  term  of  the  agreement  and  provide  for  mandatory 
principal prepayments of $1 million per quarter over the next five fiscal quarters, beginning on September 30, 2018. 

In June 2016, Mesa Airlines, as borrower, and EDC, as lender, entered into a credit agreement (the "EDC June 2016 
Credit  Facility")  pursuant  to  which  EDC  committed  to  purchase  notes  from  Mesa  Airlines  from  time  to  time  in  the 
aggregate principal amount of up to $25.0 million. The borrower's obligations under the EDC June 2016 Credit Facility 
are unsecured and guaranteed by us. The EDC June 2016 Credit Facility contains affirmative and negative covenants 
and events of default that are typical in the industry for similar financings. Each note matures on the date that is two 
years  after  such  note  was  issued.  As  of  September 30,  2018,  $5.9 million  of  borrowings  were  outstanding  under  this 
facility.

The  EDC  June  2016  Credit  Facility  also  contains  an  affirmative  covenant  that  requires  us  to  maintain  a  consolidated 
interest and rental coverage ratio above the amount specified in the agreement. As of September 30, 2018, we were in 
compliance with this covenant. 

51

Funds drawn under the EDC June 2016 Credit Facility are subject to certain arrangement and commitment fees, and 
funds drawn under the facility bear interest at (i) LIBOR plus a margin of 2.81% plus a margin benchmark of 0.49% or 
(ii) a fixed amount based on a swap rate of floating rate debt to fixed rate debt, plus a margin of 2.81%, plus a margin 
benchmark of 0.71%. Installment payments must be made on each note issued under this facility. 

Midfirst Engine Facility. In May 2015, Mesa Airlines, as borrower, and MidFirst Bank, as lender, entered into a business 
loan  agreement  and  accompanying  promissory  note  (the  "MidFirst  Credit  Facility")  pursuant  to  which  MidFirst  Bank 
committed to lend to Mesa Airlines the principal amount of $8.5 million. The borrower's obligations under the MidFirst 
Credit  Facility  are  guaranteed  by  us  and  are  secured  primarily  by  a  lien  on  certain  spare  engines  acquired  with  the 
proceeds  of  the  MidFirst  Credit  Facility  and  related  collateral.  The  MidFirst  Credit  Facility  contains  affirmative  and 
negative  covenants  and  events  of  default  that  are  typical  in  the  industry  for  similar  financings.  The  promissory  note 
matures  on  September 21,  2020.  As  of  September 30,  2018,  $3.3 million  of  borrowings  were  outstanding  under  this 
facility. As of September 30, 2018, we were in compliance with the covenants described above. 

Funds drawn under the MidFirst Credit Facility bear interest at the rate of 5.163% per annum. Installment payments of 
principal must be made on the promissory note issued under this facility.

In fiscal year 2004, we permanently financed five CRJ-700 and six CRJ-900 aircraft with $254.7 million in debt 
and in our fiscal 2005, we permanently financed five CRJ-900 aircraft with $118 million in debt. The debt bears 
interest  at  the  monthly  LIBOR  plus  3%  (5.261%  at  September 30,  2018)  and  requires  monthly  principal  and 
interest payments. As of September 30, 2018, we had $4.4 million outstanding under these notes.

notes.

In fiscal year 2014, we permanently financed 10 CRJ-900 aircraft for $88.4 million. The debt bears interest at 
the monthly LIBOR, plus a spread ranging from 1.95% to 7.25% (4.211% to 9.511% at September 30, 2018) 
and  requires  monthly  principal  and  interest  payments.  As  of  September 30,  2018,  we  had  $31.2 million 
outstanding under these notes.

In fiscal year 2014, we permanently financed eight CRJ-900 aircraft with $114.5 million in debt. The debt bears 
interest  at  5%  and  requires  monthly  principal  and  interest  payments.  As  of  September 30,  2018,  we  had 
$72.4 million outstanding under these notes. 

In fiscal year 2015, we 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% (4.971% at September 30, 2018) 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. We have 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. As of September 30, 2018, we had $122.6 million outstanding under these notes. 

In fiscal year 2016, we financed 10 E-175 aircraft with $246 million in debt under an enhanced equipment trust 
certificate ("EETC") financing arrangement. The debt bears interest ranging from 4.75% to 6.25% and requires 
semi-annual  principal  and  interest  payments.  As  of  September 30,  2018,  we  had  $209.2 million  outstanding 
under these notes. 

In  fiscal  year  2016,  we  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%  (4.598%  to 
4.718% at September 30, 2018) and require quarterly principal and interest payments. The subordinated notes 
payable  bear  interest  at  4.50%  and  require  quarterly  principal  and  interest  payments.  As  of  September 30, 
2018, we had $167.3 million outstanding under these notes.

In December 2017, we refinanced $41.9 million of debt on nine CRJ-900 aircraft (due between 2019 and 2022) 
with  $74.9 million  of  debt,  resulting  in  net  cash  proceeds  to  us  of  $30.5 million  after  transaction  related  fees. 
The senior notes payable of $46.9 million bear interest at three-month LIBOR plus 3.5% (5.898% at September 
30,  2018).  The  subordinated  notes  payable  bear  interest  at  three-month  LIBOR  plus  4.5%  (6.898%  at 
September 30, 2018). The refinanced debt requires quarterly payments of principal and interest through fiscal 
2022. As of September 30, 2018, we had $63.4 million outstanding under these notes.

(cid:3) On June 27, 2018, we 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 us of $10.4 million after transaction related fees. The notes payable 
bear interest at LIBOR, plus 3.50% and require quarterly payments of principal and interest through fiscal 2022. 
As of September 30, 2018, we had $26.9 million outstanding under these notes.

(cid:3) On June 28, 2018, we purchased nine CRJ-900 aircraft, which were previously leased under the GECAS 
Lease  Facility,  for  $76.5 million.  We  financed  the  aircraft  purchase  with  $69.6 million  in  new  debt  and 
proceeds  from  the  June  2018  aircraft  refinancing.  The  notes  payable  of  $69.6 million  bear  interest  at 
LIBOR  plus  a  spread  ranging  from  3.50%  for  the  senior  promissory  notes  to  7.50%  for  the  subordinated 

52

promissory  notes  and  require  quarterly  payments  of  principal  and  interest  through  fiscal  2022.  We 
recorded  non-cash  lease  termination  expense  of  $15.1 million  in  connection  with  the  lease  buyouts 
described above. Also, as part of the transaction, we (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. As of September 30, 2018, we had $68.2 million outstanding under these notes.

The  Aircraft  Notes  are  secured  by  the  respective  aircraft,  which  had  a  net  book  value  of  $1,047.6  million  as  of 
September 30, 2018. The weighted-average effective interest rate of the fixed and floating rate aircraft and equipment 
notes, as of September 30, 2018 and September 30, 2017, was 5.66% and 4.89%, respectively.

Maintenance Commitments 

In August 2005, we entered into a ten-year agreement with AAR, for the maintenance and repair of certain of our CRJ-
200,  CRJ-700  and  CRJ-900  aircraft.  The  agreement  has  since  been  amended  to  include  a  term  extending  through 
2021,  and  to  provide  certain  E-175  aircraft  rotable  spare  parts  with  a  term  through  December  2027.  Under  the 
agreements, we pay AAR a monthly access fee per aircraft for certain consigned inventory as well as a fixed "cost per 
flight hour" fee on a monthly basis for repairs on certain repairable parts during the term of the agreement, which fees 
are subject to annual adjustment based on increases in the cost of labor and component parts. 

In  July  2012,  we  entered  into  a  heavy  check  maintenance  contract  with  Bombardier,  to  perform  heavy  check 
maintenance on all CRJ-700 and CRJ-900 aircraft, which has been extended through November 2020. We are charged 
on a time and materials basis by Bombardier for the heavy check maintenance work performed under this agreement. 

In July 2013, we entered into an engine maintenance contract with GE to perform heavy maintenance on certain CRJ-
700, CRJ-900 and E-175 engines based on a fixed pricing schedule. The pricing may escalate annually in accordance 
with GE's spare parts catalog for engines. The engine maintenance contract extends through 2024. 

In  2014,  we  entered  into  a  ten-year  contract  with  Aviall  to  provide  maintenance  and  repair  services  on  the  wheels, 
brakes and tires of our CRJ-700 and CRJ-900 aircraft. Under the agreement, we pay Aviall a fixed "cost per landing"
fee for all landings of our aircraft during the term of the agreement, which fee is subject to annual adjustment based on 
increases in the cost of labor and component parts. 

We  entered  into  an  engine  maintenance  contract  with  StandardAero,  which  became  effective  on  June 1,  2015,  to 
perform heavy maintenance on certain CRJ-700 and CRJ-900 engines based on a fixed pricing schedule. The pricing 
may escalate annually in accordance with the GE's spare parts catalog for engines. The engine maintenance contract 
extends through 2020. 

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,  2018,  $58.1 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. 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. 

53

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 to 
the consolidated financial statements.

Revenue Recognition

Under our capacity purchase agreements, our 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  that  we  incur  in  performing  flight  services.  These  costs,  known  as  "pass-
through  costs,"  may  include  passenger  and  hull  insurance,  aircraft  property  taxes,  as  well  as  landing  fees  and 
catering. Additionally, for the E-175 aircraft owned by United, our United Capacity Agreement provides that United will 
reimburse us for heavy airframe and engine maintenance, landing gear, APUs and component maintenance, which are 
treated  as  pass-through  and  will  increase  revenue  (and  expense  for  the  same  amount)  upon  completion  of  the  work. 
We  also  receive  compensation  under  our  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. We 
record  reimbursement  of  pass-through  costs  as  pass  through  and  other  revenue  in  the  consolidated  statements  of 
operations as service is provided. In addition, our major airline partners also provide, at no cost to us, 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  our  major  airline  partners  at  no  cost  to  us  are  presented  net  in  our  consolidated 
financial  statements;  hence,  no  amounts  are  recorded  for  revenue  or  expense  for  these  items.  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.  We  recognize  revenue  under  our  capacity  purchase  agreements  when  the 
transportation is provided, including an estimate of the profit component based upon the information available at the end 
of  the  accounting  period.  All  revenue  recognized  under  our  capacity  purchase  agreements  is  presented  as  the  gross 
amount billed to our major airline partners.

Under  our  capacity  purchase  agreements  with  American  and  United,  we  are  reimbursed  under  a  fixed  rate per 
block hour, plus an amount per aircraft designed to reimburse us for certain aircraft ownership costs.

We have concluded that a component of our revenue under our American and United Capacity Purchase Agreements is 
rental income, as these agreements identify the "right of use" of a specific type and the number of aircraft over a stated 
period of time. We calculate the amount of rental income using the contractual ownership rates set forth in our American 
and  United  Capacity  Purchase  Agreements.  The  amount  deemed  to  be  rental  income  during  our  fiscal  years  ended 
September 30, 2018, 2017 and 2016 were $217.0 million, $217.6 million and $190.1 million, respectively, and has been 
included in contract revenue on our consolidated statements of income. We have not separately stated aircraft rental 
income and aircraft rental expense in our consolidated statements of operations because the use of the aircraft is not a 
separate activity of the total service provided.

Our capacity purchase agreements contain an option that allows our major airline partners to assume the contractual 
responsibility for procuring and providing the fuel necessary to operate the flights that we operate for them. Both of our 
major  airline  partners  have  exercised  this  option.  Accordingly,  we  do  not  record  an  expense  or  revenue  for  fuel  and 
related fueling costs for flying under our capacity purchase agreements.

54

Our  capacity  purchase  agreements  contain  provisions  pursuant  to  which  the  parties  could  terminate  their  respective 
agreements,  subject  to  certain  conditions.  Our  revenues  could  be  impacted  by  a  number  of  factors,  including 
amendment  or  termination  of  our  capacity  purchase  agreements,  contract  modifications  resulting  from  contract 
renegotiations  and  our  ability  to  earn  incentive  payments  contemplated  under  applicable  agreements.  In  the  event 
contracted  rates  are  not  finalized  at  a  quarterly  or  annual  financial  statement  date,  we  record  that  period's  revenues 
based  on  the  lower  of  the  prior  period's  approved  rates  or  our  estimate  of  rates  that  will  be  implemented  upon 
completion  of  negotiations.  Also,  in  the  event  we  have  a  reimbursement  dispute  with  a  major  airline  partner  at  a 
quarterly or annual financial statement date, we evaluate the dispute under established revenue recognition criteria and, 
provided the revenue recognition criteria have been met, we recognize revenue for that period based on our estimate of 
the resolution of the dispute. Accordingly, we are required to exercise judgment and use assumptions in the application 
of  our  revenue  recognition  policy.  See  "Recent Accounting  Pronouncements"  below  for  a  discussion  of  a  new 
accounting standard that we anticipate implementing beginning in our fiscal 2019.

Maintenance

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. 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 $51.2 million, $64.0 million and $90.9 million for our fiscal years ended September 30, 
2018, 2017 and 2016, respectively, of which $12.3 million, $0.3 million and $0, respectively, was pass-through expense. 
Airframe C-check expense totaled $21.5, $22.6 million and $13.2 million for our fiscal years ended September 30, 2018, 
2017, and 2016, respectively, of which $7.5 million, $4.9 million and $0, 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 "Recent Accounting 
Pronouncements" below for a discussion of a new accounting standard that is likely to have an impact on our aircraft 
lease accounting beginning in 2019.

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.

55

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 11: "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.

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,  2018,  we  had  $606.3 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, 2018. 

As of September 30, 2018, we had $323.9 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, 2018. 

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Mesa Air Group, Inc.

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, 2018 and 2017, the related consolidated statements of operations, stockholders' 
equity, and cash flows, for each of the three years in the period ended September 30, 2018, 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, 2018 and 2017, and the results of its 
operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  September  30,  2018,  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.

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, 2018, the Company served 110 cities 
in 39 states, the District of Columbia, Canada, Mexico, Cuba and the Bahamas, 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, 2018, 2017 and 2016 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 12), 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.

American Capacity Purchase Agreement 

As  of  September 30,  2018,  the  Company  operated  64  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 
64

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  7.2%  and  10.6% 
ownership interest in the Company, calculated on a fully-diluted basis as of September 30, 2018 and 2017, respectively. 
The  related  party  amounts  presented  on  the  consolidated  balance  sheets  and  statements  of  operations  pertain  to 
American. 

United Capacity Purchase Agreement 

As  of  September 30,  2018,  the  Company  operated  20  CRJ-700  and  60  E-175  aircraft  for  United  under  a  capacity 
purchase  agreement.  Subject  to  certain  early  termination  rights,  the  capacity  purchase  agreement  for  each  of  the  20 
CRJ-700  aircraft  expires  between  August  and  December  2019.  Subject  to  early  termination  rights,  the  capacity 
purchase  agreement  for  30  of  the  E-175  aircraft  (owned  by  United)  expires  between  June  2019  and  August  2020, 
subject  to  United's  right  to  extend  for  four  additional  two-year  terms  (maximum  of  eight  years).  Subject  to  early 
termination  rights,  the  capacity  purchase  agreement  for  18  of  the  E-175  aircraft  (owned  by  Mesa)  expires  between 
January  2028  and  November  2028.  During  fiscal  2017,  the  Company  and  United  expanded  the  capacity  purchase 
agreement to include, subject to early termination rights, an additional 12 E-175 aircraft (purchased by United) with the 
aircraft entering service through January 2018 for five-year terms, subject to United's right to extend for four additional 
two-year  terms  (maximum  of  eight  years).  In  exchange  for  performing  the  flight  services  under  such  agreement,  the 
Company  receives  from  United  a  fixed  monthly  minimum  amount  per  aircraft,  plus  certain  additional  amounts  based 
upon the number of flights and block hours flown during the month. Additionally, certain costs incurred by the Company 
in  performing  the  flight  services  are  "pass-through"  costs,  whereby  United  agrees  to  reimburse  the  Company  for  the 
actual  amounts  incurred  for  the  following  items:  property  tax  per  aircraft,  landing  fees,  and  additionally  for  the  E-175 
aircraft owned by United, heavy airframe and engine maintenance, landing gear, APUs and component maintenance. 
The Company also receives a profit margin based upon certain reimbursable costs under the agreement, as well as its 
operational performance in addition to a fixed profit margin. 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. 

In February 2018, the Company mutually agreed with United to temporarily remove two aircraft from service under its 
United capacity purchase agreement until the Company was able to fully staff flight operations. During the temporary 
removal, the Company agreed to pay the lease costs associated with the two E-175 aircraft, which totaled $1.9 million 
as  of  September 30,  2018.  In  June  2018,  the  Company  was  able  to  fully  staff  flight  operations  and  these  two  E-175 
aircraft were placed back into service under the United capacity purchase agreement.

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  passenger  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 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 2018, 2017 and 2016 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  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,  2018  and  2017 
was $19.9 million and $0, 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, $3.8 
million  and  $3.6 million  of  outstanding  letters  of  credit  are  required  to  be  collateralized  by  amounts  on  deposit  as  of 
September 30, 2018 and 2017, 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 $1.8 million and $1.6 million as of September 30, 2018 and 2017, 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.

66

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

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, 2018 and 2017.

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. 

67

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 

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. 

Deferred Credits 

Deferred credits consist of cost reimbursements from major airline partners related to aircraft modifications per revised 
capacity purchase agreements and costs associated with pilot training. The deferred credits are amortized on a straight-
line basis as a component of revenue over the term of the respective capacity purchase agreements. 

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, 2018, 
2017 and 2016, the Company recorded amortization of this unfavorable lease liability of $6.6 million, $6.8 million, and 
$6.8 million, respectively, as a reduction of lease expense. During the year ended September 30, 2018, the Company 
wrote off $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.

Revenue Recognition 

Under the Company's capacity purchase 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,  aircraft  property  taxes,  as  well  as  landing  fees  and 
catering. 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,  auxiliary  power  units  ("APU")  and 
component maintenance which are treated as pass-through and will increase revenue (and expense for the same amount) 
upon  completion  of  the  work.  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  Company  records  reimbursement  of  pass-through  costs  as  pass-through  and  other 
revenue  in  the  consolidated  statements  of  operations  as  service  is  provided.  In  addition,  the  Company's  major 

68

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 major airline partners 
at no cost to the Company are presented net in the Company's consolidated financial statements; hence, no amounts are 
recorded for revenue or expense for these items. 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 recognizes 
revenue under its capacity purchase agreements when the transportation is provided, including an estimate of the profit 
component based upon the information available at the end of the accounting period. All revenue recognized under these 
contracts is presented as the gross amount billed to the major airline partners. 

Under the Company's capacity purchase agreements with American and United, the Company is reimbursed under a 
fixed rate per block hour, plus an amount per aircraft designed to reimburse the Company for certain aircraft ownership 
costs. The Company has concluded that a component of its revenue under these agreements is rental income, as such 
agreements  identify  the  "right  of  use"  of  a  specific  type  and  number  of  aircraft  over  a  stated  period  of  time.  The 
Company  calculates  the  amount  of  rental  income  using  the  contractual  ownership  rates  set  forth  in  the  respective 
capacity purchase agreements. The amount deemed to be rental income during fiscal 2018, 2017 and 2016 was $217.0 
million,  $217.6 million  and  $190.1 million,  respectively,  and  has  been  included  in  contract  revenue  on  the  Company's 
consolidated statements of operations. The Company has not separately stated aircraft rental income and aircraft rental 
expense  in  the  consolidated  statements  of  operations  because  the  use  of  the  aircraft  is  not  a  separate  activity  of  the 
total service provided. 

Our  American  and  United  Capacity  Purchase  Agreements  contain  an  option  that  allows  the  major  airline  partner  to 
assume  the  contractual  responsibility  for  procuring  and  providing  the  fuel  necessary  to  operate  the  flights  that  the 
Company  operates  for  them.  Both  airlines  have  exercised  this  option.  Accordingly,  the  Company  does  not  recognize 
fuel expense or revenue for fuel on passenger flight services. 

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.  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. 

Engine overhaul expense totaled $51.2 million, $64.0 million and $90.9 million for the years ended September 30, 2018, 
2017  and  2016,  respectively,  of  which  $12.3 million,  $0.3  million  and  $0  million  was  pass-through  expense.  Airframe 
check expense totaled $21.5 million, $22.6 million and $13.2 million for the years ended September 30, 2018, 2017 and 
2016, respectively, of which $7.5 million, $4.9 million and $0 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.

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 "Recent Accounting 
Pronouncements" below for a discussion of a new accounting standard that is likely to have an impact on our aircraft 
lease accounting beginning in 2019.

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.

Correction of Immaterial Misstatement 

Subsequent to the issuance of the Company's 2016 consolidated financial statements, management determined that a 
payment  the  Company  received  in  2017  of  $4.6 million  from  a  former  vendor  for  engine  maintenance  support  credits 
should  have  been  recorded  as  a  receivable  and  a  reduction  in  engine  maintenance  expense  in  prior  years,  and  also 
identified other minor prior period adjustments for under-accrued property tax. Accordingly, the Company made a prior 
period  adjustment  to  increase  retained  earnings  by  $2.3 million  as  of  September 30,  2015  and  adjusted  accounts 
receivable, accrued property taxes, and deferred tax liability (for related income tax effects) as of September 30, 2016, 
to correct such amounts. These adjustments had no effect on the Company's previously-reported results of operations 
or  net  cash  flows  from  operating,  investing,  or  financing  activities  for  the  year  ended  September 30,  2016.  The 
Company  evaluated  these  adjustments  considering  both  quantitative  and  qualitative  factors  and  concluded  they  were 
immaterial to previously issued financial statements.

Recent Accounting Pronouncements 

In  May  2014,  the  Financial  Accounting  Standards  Board  ("FASB")  issued  ASU No. 2014-09, Revenue  from  Contracts 
with Customers (Topic 606) ("ASU 2014-09"). The standard 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  received  in  exchange  for  those  goods  or  services.  This  ASU  also  requires  additional 
disclosure  about  the  nature,  amount,  timing  and  uncertainty  of  revenue  and  cash  flows  arising  from  contracts  with 
customers, including significant judgments and changes in judgments. ASU 2014-09 allows the Company to apply the 
standard  either  retrospectively  to  each  prior  reporting  period  presented  or  retrospectively  as  a  cumulative-effect 
adjustment as of the date of adoption. In July 2015, the FASB approved a one-year deferral of the effective date of the 
new  standard,  making  it  effective  for  our  reporting  periods  beginning  October 1,  2018.  Under  the  new  standard,  the 
Company  concluded  that  individual  flights  are  distinct  services  and  these  flight  services  promised  in  a  capacity 
purchase  agreement  represent  a  series  of  services  that  should  be  accounted  for  as  a  single  performance  obligation, 
recognized  over  time  as  the  flights  are  completed.  We  do  not  expect  ASU 2014-09 to  have  a  material  impact  to  our 
financial statements. The Company anticipates applying the standard as a cumulative-effect adjustment as of the date 
of  adoption.  We  will  continue  to  monitor  industry  activities  and  any  additional  guidance  provided  by  regulators, 
standards setters, or the accounting profession and adjust our assessment and implementation plans accordingly.

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 2017, and the adoption did not have a material impact on the 
consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which provides guidance 
requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for substantially all leases, 
with  the  exception  of  short-term  leases.  Leases  will  be  classified  as  either  financing  or  operating,  with  classification 
affecting  the  pattern  of  expense  recognition  in  the  statement  of  income.  The  guidance  is  effective  for  annual  periods 
beginning  after  December 15,  2018,  with  early  adoption  permitted.  The  Company  is  currently  evaluating  the  potential 
impact of adopting this new guidance on its consolidated financial statements.

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 does not 
expect ASU 2016-15 to have a material impact to its financial statements. 

In  November  2016,  the  FASB  issued  ASU  No. 2016-18  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 expects the adoption of ASU 2016-18 
to  have  no  effect  on  our  consolidated  statements  of  operations  or  its  consolidated  balance  sheets.  ASU  2016-18  is 
expected to only result in a change in presentation of restricted cash and restricted cash equivalents on the Company's 
consolidated  statement  of  cash  flows.  The  Company  has  restricted  cash  of  $3.8 million  and  $3.6  million  as  of 
September 30, 2018 and 2017, respectively, and intends to adopt the new guidance in fiscal 2019.

Concentrations 

At  September 30,  2018,  the  Company  had  capacity  purchase  agreements  with  American  and  United.  All  of  the 
Company's consolidated revenue for the years ended September 30, 2018, 2017 and 2016 and accounts receivable at 
the  end  of  September  30,  2018  and  2017  was  derived  from  these  agreements.  The  terms  of  both  the  American  and 
United  capacity  purchase  agreements  are  not  aligned  with  the  lease  obligations  on  the  aircraft  performing  services 
under such agreements. 

Amounts billed by the Company under capacity purchase agreements are subject to the Company's interpretation of the 
applicable capacity purchase agreement and are subject to audit by the Company's major airline partners. Periodically, 
the  Company's  major  airline  partners  dispute  amounts  billed  and  pay  amounts  less  than  the  amount  billed.  Ultimate 
collection of the remaining amounts not only depends upon the Company prevailing under the applicable audit, but also 
upon the financial well-being of the major airline partner. As such, the Company periodically reviews amounts past due 
and records a reserve for amounts estimated to be uncollectible. The allowance for doubtful accounts was $1.3 million 
and $0.7 million at September 30, 2018 and 2017, 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  54%,  56%  and  64%  of  the  Company's  total  revenue  for  the  years  ended 
September 30,  2018,  2017  and  2016,  respectively.  United  accounted  for  approximately  46%,  44%  and  36%  of  the 
Company's total revenue for the years ended September 30, 2018, 2017 and 2016, 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.

2017 and 2016, respectively.

The Company recorded amortization of the unfavorable lease liability amounting to $6.6 million, $6.8 million and $6.8 
million for the years ended September 30, 2018, 2017 and 2016, respectively, as a reduction to lease expense. During 
the  year  ended  September 30,  2018,  the  Company  wrote  off  $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.

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, 2018 and 2017.

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, 2018 and 2017. 

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

The  carrying  value  and  estimated  fair  value  of  the  Company's  long-term  debt,  including  current  maturities,  were  as

The net book value of collateralized aircraft and equipment as of September 30, 2018 was $1,047.6 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,  2018,  Mesa  has  $209.2 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  August  14,  2018  the  Company  paid  down  the  outstanding  balance  on  the  CIT  Revolving  Credit  Facility  of  $25.7 
million.

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  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, 2018, 2017 and 2016. 

10. Common Stock 

The Company previously issued warrants to third parties, which had a five-year term to be converted to common stock 
at  an  exercise  price  of  $0.004  per  share.  Outstanding  warrants  to  purchase  shares  of  common  stock  are  held  by 
persons who are not U.S. citizens. The warrants are not exercisable due to 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. 
The  warrants  can  be  converted  to  common  stock  upon  warrant  holders  demonstrating  U.S.  citizenship.  During  June 
2018, the Company extended  the term  of  outstanding warrants set to expire by five years (through fiscal year  2023). 
Any warrants that were not extended were forfeited. 

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.  Our  shares  of  common  stock  became  listed  on  The 
NASDAQ Global Select Market under the symbol "MESA" effective August 10, 2018. 

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.

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 $3.8 million in offering costs.

We have not historically paid dividends on shares of our common stock. 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.

We have federal and state income tax NOL carryforwards of $415.1 million and $199.6 million, which expire in 2027-
2037 and 2019-2038, respectively.

We believe that it is more likely than not that the benefit from certain state NOL carryforwards will not be realized. In 
recognition  of  this  risk,  we  have  provided  a  valuation  allowance  of  $1.9  million  in  fiscal  year  2018  and  $2.6  million  in 
fiscal  year  2017  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, 2018.

As a result of adopting ASU 2016-09, the table of deferred tax assets and liabilities includes $0.4 million of deferred tax 
assets previously unrecognized that arose directly from, or the use of which was postponed by, tax deductions related 
to equity compensation greater than the compensation recognized for financial reporting. These previously recognized 
deferred tax assets are related to excess tax benefits incurred in years prior to September 30, 2018.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits:

Unrecognized tax benefits — October 1
Gross increases — tax positions in prior period
Gross decreases — tax positions in prior period
Gross increases — tax positions in current period
Settlement
Lapse of statute of limitations
Unrecognized tax benefits — September 30

Included in the balance of unrecognized tax benefits are $4.7 million, $7.5 million and $7.5 million of tax benefits as of 
September 30, 2018, 2017 and 2016, respectively, that, if recognized, would result in adjustments to primarily deferred 
taxes. The decrease in the year ended September 30, 2018 is a result of the change in federal tax rate that reduces the 
benefit that would be recognized if the unrecognized tax benefit was resolved favorably.

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.

We  are  subject  to  taxation  in  the  United  States  and  various  states.    As  of  September  30,  2018,  the  Company  is  no 
longer subject to U.S. federal or state examinations by taxing authorities for years prior to 1999.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax 
Cuts and Jobs Act (the "Tax Act"). The Tax Act makes 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) bonus depreciation that will allow for full expensing of qualified property. 
The Tax Act reduces the federal corporate tax rate to 21% in our fiscal year ended September 30, 2018. The Internal 
Revenue Code stipulates that the Company's fiscal year ended September 30, 2018, will have a blended corporate tax 
rate of 24.5%, which is based on the applicable tax rates before and after the Tax Act and the number of days in the 
year.

The  SEC  staff  issued  SAB  118,  which  provides  guidance  on  accounting  for  the  tax  effects  of  the  Tax  Act.  SAB  118 
provides  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  must  reflect  the 
income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a 
company's accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable 
estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional 
estimate to be included in the financial statements, it should continue 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.

In connection with our initial analysis of the impact of the Tax Act, we have recorded a discrete net tax benefit of $22.0 
million in the period ending September 30, 2018. As discussed more fully below, the Company has not completed its 
accounting  for  the  income  tax  effects  of  certain  elements  of  the  Tax  Act.  The  Company  has  recorded  provisional 
adjustments  where  reasonable  adjustments  are  available.  Where  reasonable  adjustments  are  not  available,  the 
Company  has  not  recorded  any  provisional  adjustments  and  continues  to  account  for  them  in  accordance  with  ASC 
740.

Our accounting for the following elements of the Tax Act is complete:

Reduction of U.S. federal corporate tax rate: The Act reduces the corporate tax rate to 21 percent, effective January 1, 
2018. Consequently, we have recorded a decrease related to our net deferred tax liabilities of $22.0 million, excluding 
the valuation allowance.  The Company has also estimated an increase to its valuation allowance of $0.5 million due to 
the rate change.  We have recorded a corresponding net adjustment to deferred income tax benefit of $21.5 million for 
the period ending September 30, 2018.  

Elimination  of  Corporate  AMT  and  Refund  of  AMT  Credits:  For  tax  years  beginning  after  December  31,  2017,  the 
corporate AMT was repealed.  The Act allows the use of existing corporate AMT credits to offset regular tax liability for 
tax years after December 31, 2017. AMT credits in excess of regular 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. 
We have reclassified the AMT credits to long-term receivable.

The Company was not able to make reasonable estimates or, correspondingly, record provisional adjustments for the 
following:

Valuation allowances: The Company must determine whether the state valuation allowance assessments are affected 
by  various  aspects  of  the  Tax  Act  (e.g.  section  163(j),  state  effect  of  The  Act,  net  operating  loss  carryforwards).  Any 
corresponding  determinations  relating  to  changes  in  valuation  allowances  have,  likewise,  not  been  completed  or 
recorded. 

12. 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 

79

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. The Company's Board of Directors is authorized to issue 2,500,000 shares of common stock to 
management  under  the  2018  Plan.  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.    From  inception  of  the  2018  Plan,  2,249,147 
shares have been awarded and 998,522 shares have vested.

The restricted stock activity for our years ended September 30, 2018, 2017 and 2016 is summarized as follows:

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 

80

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.

Phantom Stock 

On  October 17,  2017,  the  Company  implemented  a  share-based  payment  plan  under  which  employees,  officers, 
directors  and  other  individuals  providing  services  to  the  Company  are  eligible  to  receive  grants  of  restricted  phantom 
stock  units  ("Phantom  Stock  Plan").  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 year ended September 30, 2018 were summarized as follows:

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, 2018, there was $8.8 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, 2018, 2017 and 2016 was $12.9 million, $2.3 million 
and  $4.7  million,  respectively.  Share-based  compensation  expenses  are  recorded  in  general  and  administrative 
expenses in the consolidated statements of operations. 

13. Commitments 

At September 30, 2018, the Company leased 28 aircraft under noncancelable operating leases with remaining terms of 
up  to  5.5 years.  The  Company  has  the  option  to  terminate  certain  leases  at  various  times  throughout  the  lease.  The 
Company headquarters and other facility noncancelable operating leases have remaining terms of up to nine 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 $85.9 million, $83.8 million and 
$84.8 million for the years ended September 30, 2018, 2017 and 2016, respectively. 

Future  minimum  lease  payments  as  of  September 30,  2018,  under  noncancelable  operating  leases  are  as  follows  (in 
thousands):

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. 

14. 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.

15. 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,  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.
