sales,  an  increase  of  7.1%  compared  to  2017.  Challenges 
of  this  growth,  including  labor  issues  and  increasing  costs  of 
raw  materials,  resulted  in  a  decrease  in  net  income,  to  $42.6  
million for 2018. However, a record $151.8 million in backlog on 
December  31st  includes  price  increases  enacted  throughout  the 
past  year  adequate  to  bring  future  shipments  back  to  historical 
profit margins. Along with the price increases, improvements to 
our onboarding and new-hire training processes, and the official 
opening  of  the  NAIC  R&D  laboratory  this  year,  we  are  focused 
on setting new records in sales volume and profitability. We are 
dedicated to delivering the same excellence to our stockholders 
that we have for 30 years.

Letter from the CEO and President

Dear Fellow Stockholder,

In 2018, we celebrated our 30th anniversary as a publicly traded company. We were 

honored  to  receive  an  invitation  from  NASDAQ  to  commemorate  this  occasion  by 

ringing the opening bell for trading on The NASDAQ Stock Market last October. Our 

Company’s 30-year history includes many accomplishments and countless examples 

of challenges met and exceeded. We were presented with many challenges during 

2018,  all  while  strengthening  our  position  in  the  marketplace  and  continuing  to  

position our Company for long-term growth and profitability.

Aided by a strong economic environment, along with both an improved product line 

and strengthened sales personnel, sales in 2018 reached a record level of $433.9 

million,  which  represented  a  gain  of  7.1%  compared  to  $405.2  million  in  2017. 

Gross profit, burdened by both higher labor and raw material costs, declined 16.1% 

to $103.5 million (23.9% of sales) versus $123.4 million (30.5% of sales). SG&A  

expenses  declined  to  $47.8  million  (11.0%  of  sales)  compared  to  $49.2  million 

(12.2%  of  sales)  during  2017.  Nonetheless,  income  from  operations  decreased 

24.7% to $55.8 million (12.9% of sales) compared to $74.1 million (18.3% of sales) 

during 2017. Net income fell 21.9% to $42.6 million or $0.81 per diluted share from 

$54.5 million or $1.03 per diluted share in 2017. The Tax Cuts and Jobs Act enacted 

in December 2017 benefitted the 2017 income tax provision by $4.4 million.

STRONG FINANCIAL CONDITION

financial  condition  at  December  31,  2018  remained 
Our 
strong. The current ratio was 2.9:1. Our capital expenditures in 
the  past  year  were  $37.3  million  with  approximately  50%  of 
that  total  devoted  to  the  building  of  the  Norman  Asbjornson  
Innovation Center (NAIC) research and development laboratory.  
We estimate capital expenditures in 2019 to be in the vicinity 
of  $40.0  million,  the  bulk  of  which  will  be  devoted  to  plant 
and  machinery,  with  approximately  $3.0  million  to  complete 
the NAIC facility, which should be fully operational by the fall of 
this year. We expect the total cost of the state-of-the-art NAIC  
facility  to  be  approximately  $34-35  million.  We  continue  to  
operate 
stockholders’  equity  was 
$247.5  million,  or  $4.70  per  diluted  share,  and  our  return  
on  average  stockholder's  equity  was  17.6%.  Since  the  end 
of  2017  and  throughout  2018  we  implemented  three  price  
increases,  our  backlog  at  
increases.  Aided  by 
December  31,  2018,  climbed  86.8%  to  $151.8  million  from  
$81.2 million for the same period a year ago.

We  are  mindful  of  the  reputation  we  have  earned  as  one  of 
the  most  technologically  innovative  producers  of  the  highest  
quality,  most  efficient  products  in  the  HVAC  industry.  We  
remain dedicated to expend the necessary financial and human  
capital  to  maintain  this  reputation.  We  have  once  again  
included  a  five-year  chart  that  exhibits  our  net 
income,  
expenditures and free cash flow. It is a record in which we take 
great pride.

We  are  quite  aware  of  the  recent  discussions  concerning  the 
appropriateness  of  corporate  stock  repurchases.  We  have  
maintained stock repurchase programs from time to time since

2007,  and  during  the  past  five  years  we  have  spent  a  total  of  
$132.6  million  on  these  repurchases.  We  have  also  made  $64.7  
million  of  total  dividend  payouts  to  our  stockholders  during  that  
same  period.  We  strongly  believe  that  these  two  expenditures  
have  greatly  enhanced  stockholder  values  and  returns.  Our  cash 
flow generation and capital position also enabled the Company to 
make total capital expenditures of $142.7 million during the past 
five years.

ACQUISITION OF WATTMASTER 
CONTROLS

On  February  28,  2018,  AAON  completed  the  acquisition  of  
substantially  all  of  the  assets  of  WattMaster  Controls,  Inc.,  a 
company based in Parkville, Missouri, for $6.4 million in cash. 
WattMaster  was  a  long-time  supplier  primarily  of  controls  to 
AAON.  This  acquisition  facilitated  the  acceleration  of  AAON’s 
internal development of its own line of controls used in AAON 
products.

BOARD OF DIRECTORS AND  
EXECUTIVE LEADERSHIP CHANGES

continued 

The  Company 
to  have  healthy  Board  and  
executive officer refreshment. Caron A. Lawhorn was elected to  
AAON’s  Board  of  Directors  on  January  24,  2019.  Ms.  Lawhorn 
is a certified public accountant, and currently serves as Senior 
Vice  President  and  Chief  Financial  Officer,  of  ONE  Gas,  Inc.,  a 
standalone  one  hundred  percent  regulated  publicly  traded  
natural  gas  utility.  Prior  to  her  current  role,  she  served  as  
Senior  Vice  President,  Commercial,  a  position  she  held  from 
ONE  Gas's  separation  from  ONEOK  in  2014.  She  served  in  the 
same  position  at  ONEOK,  since  2011.  From  2009  until  2011, 
Caron  was  Senior  Vice  President,  Corporate  Planning  and  
Development  of  ONEOK  and  ONEOK  Partners,  responsible  for 
business development, strategic and long-range planning and  
capital investment. Prior to that, she was Senior Vice President  
of Financial Services and Treasurer of ONEOK.

Additionally,  on  October  29,  2018,  the  Board  of  Directors  
promoted Stephen Wakefield to Vice President of Engineering and 
Rony  Gadiwalla  to Vice  President  of  Information Technology  and 
Chief Information Officer.

Mr.  Wakefield  has  been  with  the  Company  since  1999.  Prior  to 
this  promotion,  he  most  recently  served  as  AAON’s  Director  of  
Engineering,  and  prior  to  that  held  several  engineering  roles,  
including Director of Design and Engineering Operations from 2017 
to 2018, Senior Manager of Research and Development from 2015 
to 2017, and Design Engineering Manager from 2005 to 2015.

Mr.  Gadiwalla  has  been  with  the  Company  since  2004.  Prior  to 
this  promotion,  he  most  recently  served  as  AAON’s  Director  of  
Information Technology since 2014. Prior to that, he held several IT 
roles, including Manager of Project Management Office from 2012 
to 2014, and Engineering Automation Manager from 2009 to 2012.

SALES REPRESENTATIVES 
NETWORK

We continue to enjoy the strongest group of independent sales 
representative  organizations  in  our  industry  and  our  efforts  in 
this area during 2017 contributed to our increased sales during 
2018.    In  2018,  we  changed  four  of  our  sales  representative 
firms  in  the  United  States.  Three  of  these  changes  were  the  
result  of  mergers  and  one  new  representative  firm  was  
added. Our current roster of representative firms consists of 63  
in  
individual  companies,  55 
Canada,  of  which  there  are  101 
in 
the  United  States  and  11  in  Canada.  Our  independent  sales  
representatives are key contributors to AAON’s success and were 
responsible for more than 90% of our sales during 2018.

GROWING PAINS

While this past year witnessed good sales growth, inflation of 
raw  material  prices  and  the  lack  of  experienced  labor  took  a  
significant  toll  on  our  operating  margins.  During  2018  we  
incurred  raw  material  price  increases  of  4.7%,  18.2%,  11.8% 
and  6.4%  in  copper,  galvanized  steel,  stainless  steel  and  
aluminum,  respectively.  In  an  attempt  to  offset  these  costs, 
we  implemented  three  price  increases,  one  in  late  2017  and 
two  during  the  past  year. They  were  admittedly,  too  little  too 
late. We  manufactured  and  shipped  the  lower  priced  products 
for all of 2018 and into the beginning of this year. We believe  
inflation  is  back  in  the  picture.    With  our  aggressive  price 
increases,  we  are  getting  the  backlog  to  return  to  historic  
is  two  times 
profitability.  However,  our  normal  backlog 
our  monthly  sales  but  due  to  the  economy  and  the  sales  
improvements we have made, we have in excess of four months’ 
of business.  Therefore, the price increases must work their way 
through the backlog.  The profitability returned in the last half of 
2018 and we expect that it will continue to do so in 2019.  How 
fast this occurs will depend upon inflation.  Price increases as  
required will continue.

During 2018 we incurred raw  
material price increases of 4.7%, 
18.2%, 11.8% and 6.4% in copper, 
galvanized steel, stainless steel 
and aluminum, respectively. In an 
attempt to offset these costs, we 
implemented three price increases, 
one in late 2017 and two during  
the past year… With our aggressive 
price increases, we are getting  
the backlog to return to historic  
profitability.

RECOGNITIONS, AWARDS AND 
PRODUCT IMPROVEMENTS

AAON  was  recognized  for  excellence  in  product  design  in  the 
15th  annual  Dealer  Design  Awards  Program  sponsored  by The 
Air  Conditioning  Heating  &  Refrigeration  News  magazine. 
An  independent  panel  of  contractors  acted  as  judges  in  the  
contest, which had 98 entries. AAON’s RN Series rooftop unit was 
the  Bronze  Award Winner  in  the  HVAC  Commercial  Equipment  
category.  The  ACHR  News  is  the  leading  trade  magazine  in 
the  heating,  ventilating,  air  conditioning,  and  refrigeration  
industries.

Certification, 

The  Norm  Asbjornson  Hall 
at  Montana  State  University 
was  recognized  with  a  U.S. 
Green  Building  Council  LEED  
the  
Platinum 
highest certification possible. The 
facility  is  home  to  the  university’s 
honors college and Norm Asbjornson 
College of Engineering, and officially opened 
in  December  2018.  Construction  of  the  building  was  funded 
largely  by  a  private  gift  from  Norm  Asbjornson. The  building 
features  an  energy  saving  geothermal  and  solar  heating  and 
cooling system combined with photovoltaic panels along with 
AAON  water-source  heat  pumps.  It  is  expected  to  use  roughly 
half the energy per square foot as many of the other buildings 
on the campus.

AAON  RN  Series  Rooftop  Units  are  now  offered  with  high- 
efficiency,  uncomplicated,  cost-effective 
two-stage  scroll  
compressors,  which  combine  energy  savings  with  simple  
control, for a unit with up to 20.5 IEER, part-load efficiency. This 
configuration is available with all of the same premium features 
and options of a standard AAON RN Series unit. Energy efficient 
features include double wall rigid polyurethane foam injected 
panel  construction,  microchannel  aluminum  condenser  coils, 
factory installed AAONAIRE energy recovery wheels, and direct 
drive backward curved plenum fans.

In  June,  our  air-cooled  chiller  products  were  Air-Conditioning, 
Heating  and  Refrigeration  Institute  (AHRI)  Performance  Certified, 
in  accordance  with  AHRI  Standard  550/590. This  includes  the  LF, 
LN and LZ Series chillers and packaged outdoor mechanical rooms. 
This  opens  up  our  chiller  product  line  to  additional  markets,  
locations,  and  government  projects  with  strict  energy  code  
specifications  that  require  AHRI  certification  for  chilled  water  
systems. 

In  August,  our  water-source  heat  pump  products  were  AHRI  
Performance  Certified.  Water-source  heat  pump  performance 
is  rated  in  accordance  with  the  ANSI/AHRI/ASHRAE/ISO  13256  
standard. The Company’s certified product listings are available 
on the AHRI’s Directory of Certified Product 
Performance.  AAON  products  in  the  AHRI 
certification  program  include  AAON  RN 
and  RQ  Series  water-source  heat  pump  
rooftop  units,  M2  Series  water-source  heat 
pump  modular  self-contained  units,  SB  
Series  water-source  heat  pump  vertical  self- 
contained units, and WH/WV Series small packaged 

horizontal/vertical water-source heat pump units.

We  have  made  important  changes  to  our  entire  larger  tonnage 
(45-240  tons)  RZ  product  line,  which  is  now  available  with  a  
variable  speed  compressor.  This  product  deploys  the 
latest  
technology  and  is  more  energy  efficient  and  cost  effective  than 
other units of similar size.

NORM ASBJORNSON INNOVATION  
CENTER RESEARCH & DEVELOPMENT 
LABORATORY

In  October,  we  held  an  open  house  at  the  Norm  Asbjornson  
Innovation  Center  Laboratory  (NAIC) 
for  over  500  AAON 
sales  representatives. We  displayed  all  the  capabilities  of  the  
laboratory  and  detailed  the  upcoming  sales  opportunities 
that  would  be  available  for  them  to  present  to  customers  and  
potential  customers.  Since 
that  meeting,  we  have  had  
multiple representatives and customers tour the facility during  
their visits to the factory. An official public grand opening of the 
NAIC laboratory is planned for later in 2019.

50% New Construction and 50% Replacement

WATER-SOURCE HEAT PUMP

In  2018  this  product  line  witnessed  a  115%  increase  in  unit 
sales  to  5,334  from  2,485  in  2017.  Sales  during  that  same  
period  grew  approximately  50%  to  $14.7  million  from  $9.9 
million. This  technically  advanced  new  product  line  took  two 
years  to  develop  and  we  are  no  longer  limited  by  in-house  
production problems. We introduced this product line with sizes 
from  one-half  ton  to  5  tons. This  year  we  will  be  introducing

OUTLOOK
This past year marked our 30th anniversary in business. We also 
witnessed  our  total  sales  reach  an  all-time  record.  Operating 
margins  were  restricted  by  increased  inflation  affecting  both 
raw material and labor costs. Beginning in late 2017 and for all 
of 2018, we operated behind the pricing curve due to a backlog 
in excess of four months’ of shipments rather than the normal 
two months’ of shipments.  In 2018 we began to implement an  
aggressive  pricing  posture  which  we  believe  will  beneficially 
impact our bottom line for the remainder of 2019 and into 2020.

With  a  record  backlog  and  a  strong  incoming  order  rate,  we 
believe  we  are  on  the  threshold  of  sustainable  revenue  and 
earnings  growth.  We  cannot  achieve  these  goals  without  the 
combined  support  and  cooperation  of  our  customers,  sales  
representatives

The  tight  labor  market  made  the  recruitment  and  retention  of 
experienced labor quite difficult. Beginning earlier this year, we 
initiated  new  practices  that  should  improve  and  remedy  our  
hiring and retention efforts.

This Annual Report includes  “forward-looking statements” within the  meaning of the Private Securities Litigation 
Reform Act  of  1995. Words  such  as  “expects”,  “anticipates”,  “intends”,  “plans”,  “believes”,  “seeks”,  “estimates”, 
“should”, “will”, and variations of such words and similar expressions are intended to identify such forward-looking 
statements. These statements  are not guarantees of  future performance and involve certain risks, uncertainties and 
assumptions, which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is 
expressed or forecasted in such forward-looking statements. Readers are cautioned not to place undue reliance on these 
forward-looking statements, which speak only as of the date on which they are made. We undertake no obligations to 
update  publicly  any  forward-looking  statements,  whether  as  a  result  of  new  information,  future  events  or 
otherwise. Important factors that could cause results to differ materially from those in the forward-looking statements 
include (1) the timing and extent of changes in raw material and component prices, (2) the effects of fluctuations in the
commercial/industrial new construction market, (3) the timing and extent of changes in interest rates, as well as other 
competitive factors during the year, and (4) general economic, market or business conditions.

PART I

Item 1. Business.

General Development and Description of Business

AAON, Inc., a Nevada corporation, (“AAON Nevada”) was incorporated on August 18, 1987. Our operating subsidiaries 
include AAON, Inc., an Oklahoma corporation, and AAON Coil Products, Inc., a Texas corporation. Unless the context 
otherwise requires, references in this Annual Report to “AAON”, the “Company”, “we”, “us”, “our”, or “ours” refer to 
AAON Nevada and our subsidiaries.

We  are  engaged  in  the  engineering,  manufacturing,  marketing  and  sale  of  air  conditioning  and  heating  equipment 
consisting of standard, semi-custom and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling 
units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps and coils.

Products and Markets

Our products serve the commercial and industrial new construction and replacement markets. To date, our sales have 
been primarily to the domestic market. Foreign sales accounted for approximately $14.7 million, $14.6 million, and 
$14.7 million of our sales in 2018, 2017, and 2016, respectively.  As a percent of sales, foreign sales accounted for 
approximately 3% to 4% of our net sales in each of those years.

Our rooftop and condensing unit markets primarily consist of units installed on commercial or industrial structures of 
generally less than ten stories in height. Our air handling units, self-contained units, geothermal/water-source heat 
pumps, chillers, packaged outdoor mechanical rooms and coils are suitable for all sizes of commercial and industrial 
buildings.

The size of these markets is determined primarily by the number of commercial and industrial building completions. The 
replacement  market  consists  of  products  installed  to  replace  existing  units/components  that  are  worn  or  damaged. 
Currently, over half of the industry’s market consists of replacement units.

The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally tied to 
housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as interest 
rates, the state of the economy, population growth and the relative age of the population. When new construction is 
down, we emphasize the replacement market.

Based on our 2018 sales of $433.9 million, we estimate that we have approximately a 11% share of the greater than five 
ton rooftop market and a 2% share of the less than five ton market. During 2018, approximately 50% of our sales were
generated from the renovation and replacement markets and 50% from new construction. The percentage of sales for 
new construction vs. replacement to particular customers is related to the customer’s stage of development.

1

We purchase certain components, fabricate sheet metal and tubing and then assemble and test the finished products. Our 
primary finished products consist of a single unit system containing heating and cooling in a self-contained cabinet, 
referred to in the industry as “unitary products”. Our other finished products are chillers, packaged outdoor mechanical 
rooms, coils, air handling units, condensing units, makeup air units, energy recovery units, rooftop units and geothermal/ 
water-source heat pumps.

We offer four groups of rooftop units: the RQ Series, consisting of five cooling sizes ranging from two to six tons; the 
RN Series, offered in 28 cooling sizes ranging from six to 140 tons; the RL Series, which is offered in 21 cooling sizes 
ranging from 45 to 240 tons; and the RZ Series, which is offered in 11 cooling sizes ranging from 55 to 240 tons.

We also offer the SA, SB and M2 Series as indoor packaged, water-cooled or geothermal/water-source heat pump self-
contained units with cooling capacities of three to 70 tons.

Our small packaged geothermal/water-source heat pump units consist of the WH Series horizontal configuration and WV 
Series vertical configuration, both from one-half to 30 tons.

We manufacture a LF Series air-cooled chiller, a LN Series air-cooled chiller, and a LZ Series chiller and packaged 
outdoor mechanical room, which are available in both air-cooled condensing and evaporative-condensed configurations, 
covering a range of four to 540 tons. BL Series boiler outdoor mechanical rooms are also available with 400-6,000 MBH 
heating capacity. FZ Series fluid cooler outdoor mechanical rooms are also available with a range of 50 to 450 tons.

We offer four groups of condensing units: the CB Series, two to five tons; the CF Series, two to 70 tons; the CN Series, 
55 to 140 tons; and the CL Series, 45 to 230 tons.

Our air handling units consist of the indoor F1, H3 and V3 Series and the modular M2 and M3 Series, as well as air 
handling unit configurations of the RQ, RN, RL, RZ and SA Series units.

Our energy recovery option applicable to our RQ, RN, RL, RZ and SB units, as well as our H3, V3, M2 and M3 Series 
air handling units, responds to the U.S. Clean Air Act mandate to increase fresh air in commercial structures. Our 
products are designed to compete on the higher quality end of standardized products.

Our air-cooled chillers (LF, LN and LZ Series) are certified with the Air-Conditioning, Heating, and Refrigeration 
Institute (“AHRI”) in accordance with AHRI Standard 550/590.  Our water-source heat pump products, including RN, 
RQ, M2, SB, WH and WV Series, are AHRI certified in accordance with ANSI/AHRI/ASHRAE/ISO 13256.

Performance characteristics of our products range in cooling capacity from one-half to 540 tons and in heating capacity 
from 7,200 to 9,000,000 BTUs. All of our products meet the Department of Energy’s (“DOE”) minimum efficiency 
standards, which define the maximum amount of energy to be used in producing a given amount of cooling. Many of our
units far exceed these minimum standards and are among the highest efficiency units currently available.

A typical commercial building installation requires one ton of air conditioning for every 300-400 square feet or, for a 
100,000 square foot building, 250 tons of air conditioning, which can involve multiple units.

We also offer six control options: the Pioneer Silver, Pioneer Gold, Touchscreen Controller, Orion Controller, terminal 
block for field installed controls, and factory installed customer provided controls.

Major Customers

One customer, Texas AirSystems, accounted for 10% or more of our sales during 2018, 2017, and 2016.

Sources and Availability of Raw Materials

The  most  important  materials  we  purchase  are  steel,  copper  and  aluminum,  which  are  obtained  from  domestic 
suppliers. We also purchase from other domestic manufacturers certain components, including compressors, electric 
motors and electrical controls used in our products. We attempt to obtain the lowest possible cost in our purchases of raw 
materials and components, consistent with meeting specified quality standards. We are not dependent upon any one 
source for raw materials or the major components of our manufactured products. By having multiple suppliers, we 
believe that we will have adequate sources of supplies to meet our manufacturing requirements for the foreseeable future.

We attempt to limit the impact of price fluctuations on these materials by entering into cancellable and non-cancellable 
fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw 
materials from our fixed price contracts for use in our manufacturing operations.

We have not been significantly impacted by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the 
“Dodd-Frank Act”) that contains provisions to improve transparency and accountability concerning the supply of certain 
minerals, known as “conflict minerals”, originating from the Democratic Republic of Congo and adjoining countries.

Representatives

We employ a sales  staff of 41 individuals and utilize approximately 63 independent  manufacturer representatives’
organizations (“Representatives”) having 101 offices to market our products in the United States and Canada. We also 
have one international sales organization, which utilizes 19 distributors in other countries. Sales are made directly to the 
contractor or end user, with shipments being made from our Tulsa, Oklahoma, and Longview, Texas, plants and our 
Parkville, Missouri, facility to the job site.

Our products and sales strategy focuses on niche markets. The targeted markets for our equipment are customers seeking 
products of better quality than offered, and/or options not offered, by standardized manufacturers.

To support and service our customers and the ultimate consumer, we provide parts availability through our sales offices. 
We also have factory service organizations at each of our plants. Additionally, a number of the Representatives we utilize 
have their own service organizations, which, in connection with us, provide the necessary warranty work and/or normal 
service to customers.

Warranties

Our product warranty policy is: the earlier of one year from the date of first use or 18 months from date of shipment for 
parts  only;  an  additional  four  years  for  compressors  (if  applicable);  15  years  on  aluminized  steel  gas-fired  heat 
exchangers (if applicable); 25 years on stainless steel heat exchangers (if applicable); and ten years on gas-fired heat 
exchangers in RL products (if applicable). Our warranty policy for the RQ series covers parts for two years from date of 
unit shipment. Our warranty policy for the WH and WV Series geothermal/water-source heat pumps covers parts for five 
years from the date of manufacture.

The Company also sells extended warranties on parts for various lengths of time ranging from six months to ten years. 
Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately 
priced warranty period.

Research and Development

Our  products  are  engineered  for  performance,  flexibility  and  serviceability. This  has  become  a  critical  factor  in 
competing in the heating, ventilation and air conditioning (“HVAC”) equipment industry. We must continually develop 
new and improved products in order to compete effectively and to meet evolving regulatory standards in all of our major 
product lines.

All of our Research and Development (“R&D”) activities are self-sponsored, rather than customer-sponsored. R&D
activities have involved the RQ, RN, RL and RZ (rooftop units), F1, H3, SA, V3, M2 and M3 (air handling units), LF, 
LN and LZ (chillers), CB, CF, CN and CL (condensing units), SA and SB (self-contained units), WH and WV (water-
source heat pumps), FZ (fluid coolers) and BL (boilers), as well as component evaluation and refinement, development 
of control systems and new product development. We incurred R&D expenses of approximately $13.5 million, $13.0 
million, and $12 million in 2018, 2017, and 2016, respectively.

Our Norm Asbjornson Innovation Center ("NAIC") research and development laboratory facility that open in 2019, 
includes many unique capabilities that exist nowhere else in the world. A few features of the lab include supply, return, 
and outside sound testing at actual load conditions, testing up to a 300 ton air conditioning system, testing of up to a 540 
ton chiller system, and 80 million Btu/h of gas heating test capacity. Environmental application testing capabilities 
include -20 to 140°F testing conditions, up to 8 inches per hour rain testing, up to 2 inches per hour snow testing, and up 
to 50 mph wind testing. We have the largest sound-testing chamber in the world for testing heating and air conditioning 
equipment, and the only one that can do this testing while putting the equipment under full environmental load. This will 

3

enable AAON to lead the industry in the development of quiet, energy efficient commercial and industrial heating and air 
conditioning equipment.

Ten  testing  chambers  within  the  NAIC  allow AAON  to  meet  and  maintain AHRI  (Air-Conditioning  Heating  and 
Refrigeration Institute) and DOE certification, and solidify the company’s industry position as a technological leader in 
the manufacturing of HVAC equipment. Current voluntary industry certification programs and government regulations 
only go to 63 tons of air conditioning as that is the largest environmental chamber currently available for testing. The 
NAIC contain contains both a 100 ton and a 540 ton chamber allowing us to prove to customers our capacity and 
efficiency on these larger units.

The NAIC was designed to test units well beyond the standard AHRI rating points and we offer testing services on 
AAON equipment throughout its range of application. This is very important on critical facilities where the units must 
perform properly and there is great risk in waiting to see once installed.  These same capabilities will enable AAON to 
develop new extended range of operation equipment and prove its capabilities.

Backlog

Our backlog as of February 1, 2019 was approximately $147.0 million compared to approximately $64.9 million as of 
February 1, 2018. The current backlog consists of orders considered by management to be firm and our goal is to fill 
orders within approximately 60 to 90 days after an order is deemed to become firm; however, the orders are subject to 
cancellation by the customers in which case, cancellation charges apply up to the full price of the equipment.

Working Capital Practices

Working capital practices in the industry center on inventories and accounts receivable. Our management regularly 
reviews our working capital with a view of maintaining the lowest level consistent with requirements of anticipated 
levels of operation. Our greatest needs arise during the months of July  - November, the peak season for inventory 
(primarily purchased material) and accounts receivable. Our working capital requirements are generally met by cash flow 
from operations and a bank revolving credit facility, which currently permits borrowings up to $30 million and had no 
balance outstanding at December 31, 2018. We believe that we will have sufficient funds available to meet our working 
capital needs for the foreseeable future.

Seasonality

Sales of our products are moderately seasonal with the peak period being July - November of each year due to timing of 
construction projects being directly related to warmer weather.

Competition

In the standardized market, we compete primarily with Lennox International, Inc., Trane (Ingersoll Rand Limited), York 
(Johnson Controls Inc.) and Carrier (United Technologies Corporation). All of these competitors are substantially larger 
and have greater resources than we do. Our products compete on the basis of total value, quality, function, serviceability, 
efficiency, availability of product, reliability, product line recognition and acceptability of sales outlets. However, in new 
construction where the contractor is the purchasing decision maker, we are often at a competitive disadvantage because 
of the emphasis placed on initial cost. In the replacement market and other owner-controlled purchases, we have a better 
chance of getting business since quality and long-term cost are generally taken into account.

Employees

As of February 5, 2019, we employed 2,221 direct employees and contract personnel. Our employees are not represented 
by unions. Management considers its relations with our employees to be good.

Patents, Trademarks, Licenses and Concessions

We do not consider any patents, trademarks, licenses or concessions to be material to our business operations, other than 
patents  issued  regarding  our  energy  recovery  wheel  option,  blower,  gas-fired  heat  exchanger,  evaporative-cooled 
condenser de-superheater and low leakage damper which have terms of 20 years with expiration dates ranging from 2019 
to 2033.

Environmental Matters

Laws concerning the environment that affect or could affect our operations include, among others, the Clean Water Act, 
the Clean Air Act, the Resource Conservation and Recovery Act, the Occupational Safety and Health Act, the National 
Environmental Policy Act, the Toxic Substances Control Act, regulations promulgated under these Acts, and any other
federal, state or local laws or regulations governing environmental matters. We believe that we are in compliance with 
these laws and that future compliance will not materially affect our earnings or competitive position.

We also strive to protect the environment, work with suppliers who do the same, and encompass sustainable business 
practices in our manufacturing operations.  AAON is dedicated to leading the company into a bright sustainable future. 
We have joined Sustainable Tulsa, a local non-profit organization, in creating an AAON Scor3card to implement more 
sustainable  processes  throughout  all  the  company  locations  (Tulsa,  Longview  and  Parkville).  We  recognize  that 
sustainability is both profitable and economical.

Since 2014, we have changed out our lighting to a much more energy efficient system. 80% of our lighting was Metal 
Halide and 20% was fluorescent. Currently, we are about 80-90% LED, and 10-20% fluorescent. We will be 100% LED 
by  2020.  When  you  combine  the  LED  upgrade  with  our  advanced  lighting  control  system,  AAON  saves  about
$400,000/year on electricity. We have also received a similar amount from power company rebates. These power savings
equate to about 5,000,000 kWh saved per year. The LED lighting has also created a better work environment for our 
employees and requires less maintenance.

In addition to this, we have installed more energy efficient HVAC systems, air compressors, and building insulation.
At the Tulsa facility currently paper and metal recycling are being conducted. Numerous waste streams have been 
identified  by  our  internal  GoGreen  employee  committee  that  could  be  recycled,  reused,  or  reduced.  We  are  also 
implementing a program to sort all our metals that has been identified to produce more profits. At the Longview facility 
currently metal, cardboard, and wood recycling is being conducted. The metal recycling also includes sorting all metals 
for maximum rebates. At the Parkville, facility recycling efforts are currently being researched and pursued.  We recover 
oil in our sheet metal manufacturing area, which is then recycled. The rags are washed and returned to us be used again, 
preventing them from entering a landfill.

AAON is also committed to designing and manufacturing innovative HVAC products of the highest quality, efficiency, 
and performance. Our water-source heat pumps products recover otherwise wasted energy and employ it to cool, heat, 
and provide dehumidification to a building - making it one of the most efficient and environmentally friendly systems. 
AAON packaged rooftop units with two stage compressors are optimized with high efficiency evaporator and condenser 
coils, and variable speed fans leading to an AHRI Certified performance up to 19.15 SEER and 20.2 IEER. AAON 
H3/V3  Series  energy  recovery  wheel  air  handling  units  provide  energy  efficient  100%  outside  air  ventilation,  by 
recovering energy that would otherwise be exhausted from a building. LZ Series packaged outdoor mechanical rooms are 
engineered to maximize the efficiency of the complete hydronic system - compressors, condenser, and evaporator. 
Factory installed 98% efficiency boilers with pumping packages available for applications that require hot water. Energy 
saving waterside economizers are available for chilled water systems that require cooling at low ambient conditions.

Item 1A. Risk Factors.

The following risks and uncertainties may affect our performance and results of operations. The discussion below 
contains “forward-looking statements” as outlined in the Forward-Looking Statements section above. Our ability to 
mitigate risks may cause our future results to materially differ from what we currently anticipate. Additionally, the ability 
of our competitors to react to material risks will affect our future results.

Our business can be hurt by economic conditions.

Our business is affected by a number of economic factors, including the level of economic activity in the markets in 
which we operate. Sales in the commercial and industrial new construction markets correlate to the number of new 
homes and buildings  that are built,  which in  turn is  influenced by cyclical  factors  such as interest rates, inflation, 
consumer spending habits, employment rates and other macroeconomic factors over which we have no control. In the 
HVAC business, a decline in economic activity as a result of these cyclical or other factors typically results in a decline 
in new construction and replacement purchases which could impact our sales volume and profitability.

Our results of operations and financial condition could be negatively impacted by the loss of a major customer.

From time to time in the past we derived a significant portion of our sales from a limited number of customers, and such 
concentration may continue in the future. In 2018, 2017, and 2016, one customer, Texas AirSystems, accounted for more 
than 10% of our sales. The loss of, or significant reduction in sales to, a major customer could have a material adverse 
effect on our results of operations, financial condition and cash flow. Further, the addition of new major customers in the 
future could increase our customer concentration risks as described above.

We may be adversely affected by problems in the availability, or increases in the prices, of raw materials and 
components.

Problems in the availability, or increases in the prices, of raw materials or components could depress our sales or increase 
the costs of our products. We are dependent upon components purchased from third parties, as well as raw materials such 
as steel, copper and aluminum. Occasionally, we enter into cancellable and non-cancellable contracts on terms from six 
to 18 months for raw materials and components at fixed prices. However, if a key supplier is unable or unwilling to meet 
our supply requirements, we could experience supply interruptions or cost increases, either of which could have an 
adverse effect on our gross profit.

We risk having losses resulting from the use of non-cancellable fixed price contracts.

Historically, we have attempted to limit the impact of price fluctuations on commodities by entering into non-cancellable 
fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw 
materials from our fixed price contracts for use in our manufacturing operations. These fixed price contracts are not 
accounted for using hedge accounting since they meet the normal purchases and sales exemption.

We may not be able to successfully develop and market new products.

Our future success will depend upon our continued investment in research and new product development and our ability 
to continue to achieve new technological advances in the HVAC industry. Our inability to continue to successfully 
develop and market new products or our inability to implement technological advances on a pace consistent with that of 
our competitors could lead to a material adverse effect on our business and results of operations.

We may incur material costs as a result of warranty and product liability claims that would negatively affect our 
profitability.

The development, manufacture, sale and use of our products involve a risk of warranty and product liability claims. Our 
product liability insurance policies have limits that, if exceeded, may result in material costs that would have an adverse 
effect on our future profitability. In addition, warranty claims are not covered by our product liability insurance and there 
may be types of product liability claims that are also not covered by our product liability insurance.

6

We may not be able to compete favorably in the highly competitive HVAC business.

Competition in our various markets could cause us to reduce our prices or lose market share, which could have an 
adverse  effect  on  our  future  financial  results. Substantially  all  of  the  markets  in  which  we  participate  are  highly 
competitive. The most significant competitive factors we face are product reliability, product performance, service and 
price, with the relative importance of these factors varying among our product line. Other factors that affect competition 
in the HVAC market include the development and application of new technologies and an increasing emphasis on the 
development of more efficient HVAC products. Moreover, new product introductions are an important factor in the 
market categories in which our products compete. Several of our competitors have greater financial and other resources 
than we have, allowing them to invest in more extensive research and development. We may not be able to compete 
successfully  against  current  and  future  competition  and  current  and  future  competitive  pressures  faced  by  us  may 
materially adversely affect our business and results of operations.

The loss of Norman H. Asbjornson could impair the growth of our business.

Norman H. Asbjornson, our founder, has served as our Chief Executive Officer from inception to date and President from 
inception to November 2016. He has provided the leadership and vision for our strategy and growth. Although important 
responsibilities and functions have been delegated to other highly experienced and capable management personnel, and 
our products are technologically advanced and well positioned for sales well into the future, the death, disability or 
retirement of Mr. Asbjornson could impair the growth of our business. We do not have an employment agreement with 
Mr. Asbjornson.

The Board of Directors attempts to manage this risk by continually engaging in succession planning concerning Mr. 
Asbjornson (as well as other key management personnel), as demonstrated by the Board’s appointment of Gary D. Fields 
as President of AAON in November 2016.

Our business is subject to the risks of interruptions by cybersecurity attacks.

We depend upon information technology infrastructure, including network, hardware and software systems to conduct 
our business. Despite our implementation of network and other cybersecurity measures, our information technology 
system and networks could be disrupted or experience a security breach from computer viruses, break-ins and similar 
disruptions from unauthorized tampering with our computer systems. Our security measures may not be adequate to 
protect against highly targeted sophisticated cyber-attacks, or other improper disclosures of confidential and/or sensitive 
information. Additionally, we may have access to confidential or other sensitive information of our customers, which, 
despite our efforts to protect, may be vulnerable to security breaches, theft, or other improper disclosure. Any cyber-
related attack or other improper disclosure of confidential information could have a material adverse effect on our 
business, as well as other negative consequences, including significant damage to our reputation, litigation, regulatory 
actions and increased cost.

Exposure to environmental liabilities could adversely affect our results of operations.

Our future profitability could be adversely affected by current or future environmental laws. We are subject to extensive 
and changing federal, state and local laws and regulations designed to protect the environment in the United States and in 
other parts of the world. These laws and regulations could impose liability for remediation costs and result in civil or 
criminal  penalties  in  case  of  non-compliance. Compliance  with  environmental  laws  increases  our  costs  of  doing 
business. Because these laws are subject to frequent change, we are unable to predict the future costs resulting from 
environmental compliance.

We are subject to potentially extreme governmental regulations and policies.

We always face the possibility of new governmental regulations, policies and trade agreements which could have a 
substantial or even extreme negative effect on our operations and profitability. Negotiations during the summer of  2013 
mitigated some of the negative effects of the Department of Energy Final Rule, Regulatory Identification No. 1904-
AC23, published on March 7, 2011. However, certain additional testing and listing requirements are still in place and 
scheduled to be phased in.

7

Several other intrusive component part governmental regulations are in process. If these proposals become final rules, 
the effect would be the regulation of compressors and fans in products for which the Department of Energy does not have 
current authority. This could affect equipment we currently manufacture and could have an impact on our product design, 
operations and profitability.

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and 
accountability concerning the supply of certain minerals, known as “conflict minerals”, originating from the Democratic 
Republic  of  Congo  and  adjoining  countries. As  a  result,  in August  2012,  the  SEC  adopted  annual  disclosure  and 
reporting requirements for those companies who use conflict minerals in their products. Accordingly, we began our 
reasonable country of origin inquiries in fiscal year 2013, with initial disclosure requirements beginning in May 2014. 
There are costs associated with complying with these disclosure requirements, including for due diligence to determine 
the sources of conflict minerals used in our products and other potential changes to products, processes or sources of 
supply as a consequence of such verification activities. The implementation of these rules could adversely affect the 
sourcing, supply and pricing of materials used in our products. As there may be only a limited number of suppliers 
offering “conflict free” conflict minerals, we cannot be sure that we will be able to obtain necessary conflict minerals 
from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we 
determine  that  certain  of  our  products  contain  minerals  not  determined  to  be  conflict  free  or  if  we  are  unable  to 
sufficiently verify the origins for all conflict minerals used in our products through the procedures we may implement.

Our operations could be negatively impacted by new legislation as well as changes in regulations and trade agreements, 
including tariffs and taxes.  Unfavorable conditions resulting from such changes could have a material adverse effect on 
our business, financial condition and results of operations.

We are subject to adverse changes in tax laws.

Our tax expense or benefits could be adversely affected by changes  in tax provisions,  unfavorable findings  in tax 
examinations or differing interpretations by tax authorities. We are unable to estimate the impact that current and future 
tax proposals and tax laws could have on our results of operations. We are currently subject to state and local tax 
examinations for which we do not expect any major assessments.

We are subject to international regulations that could adversely affect our business and results of operations.

Due to our use of representatives in foreign markets, we are subject to many laws governing international relations, 
including those that prohibit improper payments to government officials and commercial customers, and restrict where
we can do business, what information or products we can supply to certain countries and what information we can 
provide to a non-U.S. government, including but not limited to the Foreign Corrupt Practices Act, U.K. Bribery Act and 
the U.S. Export Administration Act. Violations of these laws, which are complex, may result in criminal penalties or 
sanctions that could have a material adverse effect on our business, financial condition and results of operations.

Operations may be affected by natural disasters, especially since most of our operations are performed at a single 
location.

Natural disasters such as tornadoes and ice storms, as well as accidents, acts of terror, infection and other factors beyond 
our control could adversely affect our operations. Especially, as our facilities are in areas where tornadoes are likely to 
occur, and the majority of our operations are at our Tulsa facilities, the effects of natural disasters and other events could
damage our facilities and equipment and force a temporary halt to manufacturing and other operations, and such events 
could consequently cause severe damage to our business. We maintain insurance against these sorts of events; however, 
this is not guaranteed to cover all the losses and damages incurred.

If we are unable to hire, develop or retain employees, it could have an adverse effect on our business.

We  compete  to  hire  new  employees  and  then  seek  to  train  them  to  develop  their  skills.  We  may  not  be  able  to 
successfully recruit, develop and retain the personnel we need. Unplanned turnover or failure to hire and retain a diverse, 
skilled workforce, could increase our operating costs and adversely affect our results of operations.

Variability in self-insurance liability estimates could impact our results of operations.

8

We self-insure for employee health insurance and workers’ compensation insurance coverage up to a predetermined 
level, beyond which we maintain stop-loss insurance from a third-party insurer for claims over $200,000 and $750,000 
for employee health insurance claims and workers’ compensation insurance claims, respectively. Our aggregate exposure 
varies from year to year based upon the number of participants in our insurance plans. We estimate our self-insurance 
liabilities using an analysis provided by our claims administrator and our historical claims experience. Our accruals for 
insurance reserves reflect these estimates and other management judgments, which are subject to a high degree of 
variability. If the number or severity of claims for which we self-insure increases, it could cause a material and adverse 
change to our reserves for self-insurance liabilities, as well as to our earnings.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

As  of  December 31,  2018,  we  own  all  of  our  Tulsa,  Oklahoma,  and  Longview,  Texas,  facilities,  consisting  of 
approximately 1.76 million square feet of space for office, manufacturing, warehouse, assembly operations and parts
sales. We believe that our facilities are well maintained and are in good condition and suitable for the conduct of our 
business.

Our  plant  and  office  facilities  in  Tulsa,  Oklahoma,  consist  of  a  342,000  sq.  ft.  building  (327,000  sq.  ft.  of 
manufacturing/warehouse space and 15,000 sq. ft. of office space) located on a 12-acre tract of land at 2425 South Yukon 
Avenue, and a 940,000 sq. ft. manufacturing/warehouse building and a 70,000 sq. ft. office building located on an 
approximately 78-acre tract of land across the street from the original facility (2440 South Yukon Avenue) (the “Tulsa 
facilities”).

Our  manufacturing area is in  heavy industrial type buildings,  with some coverage by overhead cranes, containing 
manufacturing  equipment  designed  for  sheet  metal  fabrication  and  metal  stamping. The  manufacturing  equipment 
contained  in  the  facilities  consists  primarily  of  automated  sheet  metal  fabrication  equipment,  supplemented  by 
presses. Assembly lines consist of six cart-type conveyor lines and one roller-type conveyor line with variable line speed 
adjustment, which are motor driven. Subassembly areas and production line manning are based upon line speed.

In 2018, construction continued on a new engineering research and development laboratory at the Tulsa facilities, since 
named the Norman Asbjornson Innovation Center.  The three-story 134,000 square foot stand alone facility will be both 
an acoustical and a performance measuring laboratory.  The new facility will consist of ten test chambers allowing 
AAON  to  meet  and  maintain  industry  certifications.    This  facility  is  located  West  of  the  940,000  sq.  ft. 
manufacturing/warehouse building at 2425 South Yukon Avenue.

In 2018, we purchased a 13,500 sq. ft. stand alone building (7,500 sq. ft. warehouse and 6,000 sq. ft. office) which will 
be utilized as an additional retail parts store to provide our customers more accessibly to our products.  The building is 
on approximately one acre and is located at 9528 E 51st St in Tulsa, Oklahoma.  We expect to open the retail parts store 
in early 2019.

Our operations in Longview, Texas, are conducted in a plant/office building at 203-207 Gum Springs Road, containing 
263,000 sq. ft. on 35.0 acres. The manufacturing area (approximately 256,000 sq. ft.) is located in three 120-foot wide 
sheet  metal  buildings  connected  by  an  adjoining  structure. The  remaining  7,000  square  feet  are  utilized  as  office 
space. The facility is built for light industrial manufacturing.

Our operations in Parkville, Missouri, are conducted in a leased plant/office at 8500 NW River Park Drive, containing
48,000 sq. ft. We believe that the leased facility is well maintained and in good condition and suitable for the conduct of 
our business.

Item 3. Legal Proceedings.

We are not a party to any pending legal proceeding which management believes is likely to result in a material liability 
and no such action has been threatened against us, or, to the best of our knowledge, is contemplated.

Use of Non-GAAP Financial Measure

To  supplement  the  Company’s  consolidated  financial  statements  presented  in  accordance  with  generally  accepted 
accounting principles (“GAAP”), an additional non-GAAP financial measure is provided and reconciled in the following 
table. The Company believes that this non-GAAP financial measure, when considered together with the GAAP financial 
measures, provides information that is useful to investors in understanding period-over-period operating results. The 
Company believes that this non-GAAP financial measure enhances the ability of investors to analyze the Company’s 
business trends and operating performance.

EBITDAX

EBITDAX (as defined below) is presented herein and reconciled from the GAAP measure of net income because of its 
wide  acceptance  by  the  investment  community  as  a  financial  indicator  of  a  company’s  ability  to  internally  fund 
operations.

The Company defines EBITDAX as net income, plus (1) depreciation, (2) amortization of bond premiums, (3) share-
based compensation, (4) interest (income) expense and (5) income tax expense. EBITDAX is not a measure of net 
income or cash flows as determined by GAAP.

The  Company’s  EBITDAX  measure  provides  additional  information  which  may  be  used  to  better  understand  the 
Company’s  operations.  EBITDAX  is  one  of  several  metrics  that  the  Company  uses  as  a  supplemental  financial 
measurement in the evaluation of its business and should not be considered as an alternative to, or more meaningful than, 
net  income,  as  an  indicator  of  operating  performance.  Certain  items  excluded  from  EBITDAX  are  significant 
components in understanding and assessing a company’s financial performance. EBITDAX, as used by the Company, 
may not be comparable to similarly titled measures reported by other companies. The Company believes that EBITDAX 
is a widely followed measure of operating performance and is one of many metrics used by the Company’s management 
team, and by other users of the Company’s consolidated financial statements.

The  following  table  provides  a  reconciliation  of  net  income  (GAAP)  to  EBITDAX  (non-GAAP)  for  the  periods 
indicated:

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview

We engineer, manufacture, market and sell air conditioning and heating equipment consisting of standard, semi-custom 
and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling units, makeup air units, energy
recovery units, condensing units, geothermal/water-source heat pumps and coils. These products are marketed and sold 
to retail, manufacturing, educational, lodging, supermarket, medical and other commercial industries. We market our 
products to all 50 states in the United States and certain provinces in Canada.

Our business can be affected by a number of economic factors, including the level of economic activity in the markets in 
which we operate. The recent uncertainty of the economy has negatively impacted the commercial and industrial new 
construction  markets.  A  further  decline  in  economic  activity  could  result  in  a  decrease  in  our  sales  volume  and 
profitability. Sales in the commercial and industrial new construction markets correlate closely to the number of new 
homes and buildings  that are built,  which in  turn is  influenced by cyclical  factors  such as interest rates, inflation, 
consumer spending habits, employment rates and other macroeconomic factors over which we have no control.

We sell our products to property owners and contractors through a network of manufacturers’ representatives and our 
internal sales force. The demand for our products is influenced by national and regional economic and demographic 
factors. The commercial and industrial new construction market is subject to cyclical fluctuations in that it is generally 
tied to housing starts, but has a lag factor of six to 18 months. Housing starts, in turn, are affected by such factors as 
interest rates, the state of the economy, population growth and the relative age of the population. When new construction 
is down, we emphasize the replacement market. The new construction market in 2018 continued to be unpredictable and
uneven. Thus, throughout the year, we emphasized promotion of the benefits of AAON equipment to property owners in 
the replacement market.

The principal components of cost of goods sold are labor, raw materials, component costs, factory overhead, freight out 
and engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, copper 
and  aluminum  and  are  obtained  from  domestic  suppliers.  We  also  purchase  from  domestic  manufacturers  certain 
components, including compressors, motors and electrical controls.

The price levels of our raw materials fluctuate given that the market continues to be volatile and unpredictable as a result 
of the uncertainty related to the U.S. economy and global economy. For the year ended December 31, 2018, the prices for 
copper, galvanized steel, stainless steel and aluminum increased approximately 4.75%, 18.18%, 11.76% and 6.43%, 
respectively, from 2017. For the year ended December 31, 2017, the prices for copper, galvanized steel and stainless steel 
increased approximately 6.2%, 15.8%, 4.4% and 2.4%, respectively, from 2016.

We attempt to limit the impact of price fluctuations on these materials by entering into cancellable and non-cancellable 
fixed price contracts with our major suppliers for periods of six to 18 months. We expect to receive delivery of raw 
materials from our fixed price contracts for use in our manufacturing operations.

The following are highlights of our results of operations, cash flows, and financial condition:

• We continue to see growth and improvement in our water-source heat pump line that increased revenues by 

$4.7 million.

13

•
•

•

Our warranty expense has stabilized and we expect to see continued improvement.
The Company completed the acquisition of Wattmaster Controls, Inc. for $6.4 million.  This acquisition was
strategic in accelerating the development of our own electronic controllers for air distribution.
The Company struggled to maintain its gross profit due to elevated staffing levels, increasing material prices 
and changes in personnel.

• We spent $37.3 million in capital expenditures in 2018, continuing our work on such projects as our new 
research and development lab, water-source heat pump production line, as well as other internal development 
projects.

• We increased our cash dividends, paying $16.7 million in 2018 compared to $13.7 million in 2017.

The principal components of cost of sales are labor, raw materials, component costs, factory overhead, freight out and 
engineering expense. The principal high volume raw materials used in our manufacturing processes are steel, copper and 
aluminum, which are obtained from domestic suppliers.   As shown below, our raw material prices increased during the 
year.  Additionally, in January 2018, the Company paid all employees a one-time bonus of $1,000 per employee as a 
result of the Tax Cuts and Jobs Act (the “Act”) which lowered the federal corporate tax rate from 35% to 21%. This 
bonus increased cost of sales by $1.9 million, excluding taxes and benefits. The Company maintained a higher level of 
workforce through the end of 2017 and beginning of 2018 in anticipation of our growing business.   The growth in order 
intake during the beginning of 2018 did not occur as quickly as anticipated.  The Company has been working and 
continues to work on managing its staffing levels to improve our efficiency.

The Company experienced a decrease in warranty claims paid of 9% in 2018.  Additionally, the Company had a change 
in estimate in how it calculates its estimated failure rate that is applied to sales to estimate our potential future liability 
for warranty claims.  This change in estimate reduced our accrual, and thus our expense, by $0.9 million.  Our profit 
sharing expenses are also down due to lower earnings.  Our advertising expense decreased due to cost savings on our
annual  sales show.    Professional  fees  have  increased  related  to  additional  services  and  work  performed  for  the 
Wattmaster acquisition.  These fees are not expected to be recurring.  Our other expenses have increased due to sales 
concessions granted to our customers.

The overall increase in SG&A was primarily due to increased warranty expenses.  The Company’s warranty expense 
increased due to the increase in the failure rate used in calculating our accrual for warranty liability.  The failure rate 
increased due to the approximately $4.5 million or 110% increase in warranty claims in 2017.

Factors  affecting  the  increase  in  warranty  claims  were:  (1)  changes  in  personnel  that  resulted  in  a  less  stringent 
application of the warranty claim policy, (2) allowing our independent sales representatives to submit a one-time clean-
up of old warranty claims not previously submitted to the Company increased claims by approximately $1.0 million, (3) 
two  specific  job  failures,  involving  multiple  units,  increased claims  by  approximately  $1.1  million,  and  (4)  paint 
department failures which increased claims by approximately $0.8 million.  Claims related to the specific job and paint 
department failures may continue into 2018.

The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017.  As a result of the changes provided under 
the Act, the Company adjusted its deferred tax assets and liabilities existing at the date of enactment using the newly 
enacted rates for the periods when they are expected to be realized.    This remeasurement resulted in a benefit to income 
taxes of $4.4 million.

Liquidity and Capital Resources

Our working capital and capital expenditure requirements are generally met through net cash provided by operations and 
the occasional use of the revolving bank line of credit based on our current liquidity at the time.

Our  cash  and  cash  equivalents  decreased  $19.5  million  from  December 31,  2017  to  December 31,  2018.  As  of 
December 31, 2018, we had $2.0 million in cash and cash equivalents.

17

On July 26, 2018 we renewed our $30.0 million line of credit with BOKF, NA dba Bank of Oklahoma (“Bank of 
Oklahoma”). Under the line of credit, there was one standby letter of credit of $1.3 million as of December 31, 2018. At 
December 31, 2018 we have $28.7 million of borrowings available under the revolving credit facility. No fees are 
associated with the unused portion of the committed amount.

As of December 31, 2018 and 2017, there were no outstanding balances under the revolving credit facility. Interest on 
borrowings is payable monthly at LIBOR plus 2.0%. The weighted average interest rate was 4.2% and 3.5% for the years 
ended December 31, 2018 and 2017, respectively.

At December 31, 2018, we were in compliance with all of the covenants under the revolving credit facility. We are 
obligated to comply with certain financial covenants under the revolving credit facility. These covenants require that we 
meet certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At December 31, 
2018, our tangible net worth was $247.5 million, which meets the requirement of being at or above $175.0 million. Our 
total liabilities to tangible net worth ratio was 0.2 to 1.0 which meets the requirement of not being above 2 to 1.

The Board has authorized three stock repurchase programs for the Company. The Company may purchase shares on the 
open market from time to time, up to a total of 5.7 million shares. The Board must authorize the timing and amount of 
these purchases. Effective May 24, 2016, the Board authorized up to $25.0 million in open market repurchases and on
June 2, 2016, the Company executed a repurchase agreement in accordance with the rules and regulations of the SEC 
allowing the Company to repurchase an aggregate amount of $25.0 million or a total of approximately 2.0 million shares 
from the open market. The repurchase agreement expired on April 15, 2017. In May 2018, the Board authorized up 
to $15.0 million in open market repurchases and on May 18, 2018, the Company executed a repurchase agreement in 
accordance with the rules and regulations of the SEC allowing the Company to repurchase shares from the open market. 
The agreement expires on March 1, 2019. The Company also has a stock repurchase arrangement by which employee-
participants in our 401(k) savings and investment plan are entitled to have shares in AAON, Inc. stock in their accounts 
sold to the Company. The maximum number of shares to be repurchased is contingent upon the number of shares sold by
employee-participants. Lastly, the Company repurchases shares of AAON, Inc. stock from certain of its directors and 
employees for payment of statutory tax withholdings on stock transactions. All other repurchases from directors or 
employees are contingent upon Board approval. All repurchases are done at current market prices.

Based  on  historical  performance  and  current  expectations,  we  believe  our  cash  and  cash  equivalents  balance,  the 
projected cash flows generated from our operations, our existing committed revolving credit facility (or comparable
financing) and our expected ability to access capital markets will satisfy our working capital needs, capital expenditures 
and other liquidity requirements associated with our operations in 2019 and the foreseeable future.

Cash flows from operating activities decreased in 2017 primarily due to increased purchases of raw material during the 
year arising from stocking of parts needed for the water-source heat pump line.  Additionally, the Company began 
stocking water-source heat pump units which resulted in larger amounts of finished goods on hand at the end of the year. 
In 2018, the Company increased purchases of metals where lower prices could be obtained in an effort to help manage 
our material costs.

19

Cash Flows from Investing Activities

Cash flows used in investing activities increased primarily due our February 2018 business combination.

The capital expenditure program for 2019 is estimated to be approximately $40.0 million. The capital expenditures for 
2019 relate to the completion of our R&D lab and water-source heat pump lines, along with expansion of our Tulsa 
facility.   Many of these projects are subject to review and cancellation at the discretion of our CEO and Board of 
Directors without incurring substantial charges.

Cash Flows from Financing Activities

Cash flows used in financing activities increased due to open market buybacks following the May 2018 repurchase 
agreement.

Off-Balance Sheet Arrangements

We are not party to any off-balance sheet arrangements that have or are reasonably likely to have a material current or 
future  effect  on  our  financial  condition,  changes  in  financial  condition,  revenues,  expenses,  results  of  operations, 
liquidity, capital expenditures or capital resources.

Commitments and Contractual Agreements

We had no material contractual purchase agreements as of December 31, 2018, except for one contractual purchase 
obligation for approximately $2.2 million that expires in December 2019.

Contingencies

We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor these 
claims and legal actions and frequently consult with our legal counsel to determine whether they may, when resolved,
have a material adverse effect on our financial position, results of operations or cash flows and we accrue and/or disclose 
loss contingencies as appropriate. We have concluded that the likelihood is remote that the ultimate resolution of any 
pending litigation or claims will be material or have a material adverse effect on the Company’s business, financial 
position, results of operations or cash flows.

Critical Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 
of America (“US GAAP”) requires management to make estimates and assumptions about future events, and apply 
judgments that affect the reported amounts of assets, liabilities, revenue and expenses in our consolidated financial 
statements and related notes. We base our estimates, assumptions and judgments on historical experience, current trends 
and other factors believed to  be relevant at  the time our consolidated financial  statements are prepared. However, 
because future events and their effects cannot be determined with certainty, actual results could differ from our estimates 
and assumptions, and such differences could be material. We believe the following critical accounting policies affect our 
more significant estimates, assumptions and judgments used in the preparation of our consolidated financial statements.

Inventory Reserves – We establish a reserve for inventories based on the change in inventory requirements due to 
product line changes, the feasibility of using obsolete parts for upgraded part substitutions, the required parts needed for 
part supply sales, replacement parts and for estimated shrinkage.

Warranty – A  provision  is  made  for  estimated  warranty  costs  at  the  time  the  product  is  shipped  and  revenue  is 
recognized. Our product warranty policy is: the earlier of one year from the date of first use or 18 months from date of 
shipment for parts only; an additional four years for compressors (if applicable); 15 years on aluminized steel gas-fired 
heat exchangers (if applicable); 25 years on stainless steel heat exchangers (if applicable); and ten years on gas-fired heat 
exchangers in RL products (if applicable). Our warranty policy for the RQ series covers parts for two years from date of 
unit shipment. Our warranty policy for the WH and WV Series geothermal/water-source heat pumps covers parts for five 
years from the date of manufacture.  Warranty expense is estimated based on the warranty period, historical warranty 
trends and associated costs, and any known identifiable warranty issue.

20

Due to the absence of warranty history on new products, an additional provision may be made for such products. Our 
estimated future warranty cost is subject to adjustment from time to time depending on changes in actual warranty trends 
and cost experience. Should actual claim rates differ from our estimates, revisions to the estimated product warranty 
liability would be required.

Stock Compensation – We measure and recognize compensation expense for all share-based payment awards made to 
our employees and directors, including stock options and restricted stock awards, based on their fair values at the time of 
grant. Compensation expense is recognized on a straight-line basis during the service period of the related share-based 
compensation award. Forfeitures are accounted for as they occur. The fair value of each option award and restricted stock 
award is estimated on the date of grant using the Black-Scholes-Merton option pricing model. The use of the Black-
Scholes-Merton option valuation model requires the input of subjective assumptions such as: the expected volatility, the 
expected term of the options granted, expected dividend yield, and the risk-free rate.

New Accounting Pronouncements

Changes  to  U.S.  GAAP  are  established  by  the  Financial  Accounting  Standards  Board  (“FASB”)  in  the  form  of 
accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification.

We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either 
not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The ASU will replace previous lease accounting 
guidance in U.S. GAAP.  The ASU requires the recognition of lease assets and lease liabilities by lessees for those leases 
classified as operating leases. The ASU retains a distinction between finance leases and operating leases. The ASU is 
effective for the Company beginning January 1, 2019.

The following ASUs have been issued in 2018 with the same effective dates and transition requirements:

•

•
•

•

ASU 2018-01, Land Easement Practical Expedient, which provides a relief from certain land easements held 
before the effective date.
ASU 2018-10, Leases: Codification Improvements, which provides clarification for various areas of Topic 842.
ASU 2018-11, Leases: Targeted Improvements, which provides clarification for several areas of Topic 842: 
comparative reporting requirements, an optional method of adoption (the transition method) and separating 
lease and non lease component for lessors.
ASU 2018-20, Leases: Narrow-Scope Improvement for Lessors, which provided clarification to lessors for sales 
taxes, variable payments and other costs.

The Company historically does not enter into numerous or material lease agreements to support its manufacturing 
operations. The Company typically enters into lease agreements that are less than a year and for leases on assets such as 
warehouse  vehicles  and  office  equipment. The  Company  assumed  a  multi-year  facility  lease  in  the  WattMaster 
acquisition. The  Company  has  completed  the  process  of  determining  our  contracts  to  which  this  new  guidance 
applies. The Company does not expect this new guidance to have a significant impact on the consolidated financial 
statements  due  the  non-material  monetary  amount  of the  total  leased  assets  under  the  new  applicable  guidance.  
Furthermore, we have elected to apply the short-term lease accounting policy election to all short-term leases under the 
applicable guidance.  Under the policy election the lessee does not recognize a short-term lease liability or right-of-use 
asset on its balance sheet.

The Company will elect the transition method, which becomes effective upon the date of adoption of ASU 2016-02 
discussed above. The transition method allows entities to initially apply the new leases standard at the adoption date 
(January 1, 2019) and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the 
period of adoption.  We expect the cumulative-effect adjustments to the opening balance to be immaterial to the financial 
statements as a whole.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements: Changes to the Disclosure Requirement for 
Fair Value Measurements.  The ASU includes additional disclosure requirements for unrealized gains and losses for  
Level 3 fair value measurement and significant observable inputs used to develop Level 3 fair value measurements.  The 
ASU is effective for the Company beginning after December 15, 2019.  We do not expect ASU 2018-13 will have a 
material effect on our consolidated financial statements and notes thereto.

21

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other. The ASU simplifies how an entity is 
required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a
goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of 
that goodwill. We will be required to perform our annual goodwill impairment test by comparing the fair value of a 
reporting unit with its carrying amount. In the event the carrying amount exceeds the reporting unit’s fair value, a 
goodwill impairment charge for the excess will be recorded (not exceeding the recorded amount of the reporting unit’s
goodwill). The ASU  is  effective  for  the  Company  beginning April  1,  2020,  and  requires  a  prospective  method  of 
adoption, although early adoption is permitted for annual goodwill impairment tests performed on testing dates on or 
after January 1, 2017. We adopted this ASU effective January 1, 2018.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Commodity Price Risk

We are exposed to volatility in the prices of commodities used in some of our products and, occasionally, we use fixed 
price cancellable and non-cancellable contracts with our major suppliers for periods of six to 18 months to manage this 
exposure.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
AAON, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of AAON, Inc. (a Nevada corporation) and subsidiaries 
(the “Company”) as of December 31, 2018 and 2017, and the related consolidated statements of income, stockholders’
equity,  and  cash  flows  for each  of  the  three  years  in  the  period  ended  December  31,  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 December 31, 2018 and 2017, and the results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with
accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2018, based on criteria 
established in the 2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (“COSO”), and our report dated February 28, 2019 expressed an unqualified opinion.

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 
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. 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 supporting 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.

AAON, Inc. and Subsidiaries
Notes to Consolidated Financial Statements
December 31, 2018

1. Business Description

AAON, Inc. is a Nevada corporation which was incorporated on August 18, 1987. Our operating subsidiaries include 
AAON,  Inc.,  an  Oklahoma  corporation  and  AAON  Coil  Products,  Inc.,  a  Texas  corporation  (collectively,  the 
“Company”). The Consolidated Financial Statements include our accounts and the accounts of our subsidiaries.

We  are  engaged  in  the  engineering,  manufacturing,  marketing  and  sale  of  air  conditioning  and  heating  equipment 
consisting of standard, semi-custom and custom rooftop units, chillers, packaged outdoor mechanical rooms, air handling 
units, makeup air units, energy recovery units, condensing units, geothermal/water-source heat pumps and coils.

2. Summary of Significant Accounting Policies

Principles of Consolidation

These financial statements are prepared in accordance with accounting principles generally accepted in the United States 
of America (“U.S. GAAP”). The accompanying consolidated financial statements include the accounts of the Company 
and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.

Cash and Cash Equivalents

We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash 
equivalents. Cash and cash equivalents consist of bank deposits and highly liquid, interest-bearing money market funds. 
The Company’s cash and cash equivalents are held in a few financial institutions in amounts that exceed the insurance
limits of the Federal Deposit Insurance Corporation. However, management believes that the Company’s counterparty 
risks are minimal based on the reputation and history of the institutions selected.

Investments

Certificates of Deposit

We held no certificates of deposit at December 31, 2018 and $2.9 million in certificates of deposit at  December 31, 
2017.

Investments Held to Maturity

At December 31, 2018, we held no investments.  We record the amortized cost basis and accrued interest of the corporate 
notes and bonds in the Consolidated Balance Sheets. We record the interest and amortization of bond premium to interest 
income in the Consolidated Statements of Income.

The  following  summarizes  the  amortized  cost  and  estimated  fair  value  of  our  investments  held  to  maturity  at  
December 31, 2017:

We evaluate these investments for other-than-temporary impairments on a quarterly basis. We do not believe there was 
an other-than-temporary impairment for our investments at December 31, 2017.

Accounts and Note Receivable

Accounts and note receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. We 
generally do not require that our customers provide collateral. The Company determines its allowance for doubtful 
accounts by considering a number of factors, including the credit risk of specific customers, the customer’s ability to pay 
current obligations,  historical trends, economic and  market conditions and the age of  the receivable. Accounts are 
considered  past  due  when  the  balance  has  been  outstanding  for  ninety  days  past  negotiated  credit  terms. Past  due 
accounts are generally written-off against the allowance for doubtful accounts only after all collection attempts have 
been exhausted.

Concentration of Credit Risk

Our customers are concentrated primarily in the domestic commercial and industrial new construction and replacement
markets. To date, our sales have been primarily to the domestic market, with foreign sales accounting for approximately 
3%, 4%, and 4% of revenues for the years ended December 31, 2018, 2017, and 2016, respectively. One customer, Texas 
AirSystems, accounted for 10% or more of our sales during 2018, 2017, or 2016. No customer accounted for 5% or 
more of our accounts receivable balance at December 31, 2018 or 2017.

Inventories

Inventories are valued at the lower of cost or market using the first-in, first-out (“FIFO”) method. Cost in inventory 
includes purchased parts and materials, direct labor and applied manufacturing overhead. We establish an allowance for 
excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for 
supply and replacement parts.

Property, Plant and Equipment

Property, plant and equipment, including significant improvements, are recorded at cost, net of accumulated depreciation. 
Repairs and maintenance and any gains or losses on disposition are included in operations.

Depreciation is computed using the straight-line method over the following estimated useful lives:

Buildings

Machinery and equipment

Furniture and fixtures

Business Combinations

3-40 years

3-15 years

3-7 years

We record the assets acquired and liabilities assumed in a business combination at their acquisition date fair values.

Fair Value Financial Instruments and Measurements

The carrying amounts of cash and cash equivalents, receivables, accounts payable and accrued liabilities approximate
fair value because of the short-term maturity of the items. The carrying amount of the Company’s revolving line of 
credit, and other payables, approximate their fair values either due to their short term nature, the variable rates associated
with the debt or based on current rates offered to the Company for debt with similar characteristics.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an 
orderly transaction between market participants at the measurement date. Fair value is based upon assumptions that 
market participants  would use  when pricing an asset or liability. We use the following fair value hierarchy,  which 
prioritizes valuation technique inputs used to measure fair value into three broad levels:

•

Level 1: Quoted prices in active markets for identical assets and liabilities that we have the ability to access at 
the measurement date.

30

•

•

Level 2:  Inputs  (other  than  quoted  prices  included  within  Level 1)  that  are  either  directly  or  indirectly 
observable for the asset or liability, including (i) quoted prices for similar assets or liabilities in active markets, 
(ii) quoted prices for identical or similar assets or liabilities in inactive markets, (iii) inputs other than quoted 
prices that are observable for the asset or liability, and (iv) inputs that are derived from observable market data 
by correlation or other means.
Level 3: Unobservable inputs for the asset or liability including situations where there is little, if any, market 
activity for the asset or liability. Items categorized in Level 3 include the estimated business combination fair 
values of property, plant and equipment, intangible assets and goodwill.

The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to 
unobservable inputs (Level 3). In some cases, the inputs used to measure fair value might fall into different levels of the 
fair value hierarchy. The lowest level input that is significant to a fair value measurement determines the applicable level 
in the fair value hierarchy. Assessing the significance of a particular input to a fair value measurement requires judgment, 
considering factors specific to the asset or liability.

Intangible Assets

Our intangible assets include various trademarks, service marks and technical knowledge acquired in our February 2018
business combination (see Note 4). We amortize our intangible assets on a straight-line basis over the estimated useful 
lives of the assets. We evaluate the carrying value of our amortizable intangible assets for potential impairment when 
events and circumstances warrant such a review.

Goodwill

Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual 
assets acquired, net of liabilities assumed. Goodwill at December 31, 2018 is deductible for income tax purposes.

Goodwill is not amortized, but instead is evaluated for impairment at least annually. We perform our annual assessment 
of impairment during the fourth quarter of our fiscal year, and more frequently if circumstances warrant.

To perform this assessment, we first consider qualitative factors to determine whether it is more likely than not that the 
fair value of the reporting unit exceeds its carrying amount. If we conclude that it is more likely than not that the fair 
value of a reporting unit does not exceed its carrying amount, we calculate the fair value for the reporting unit and 
compare the amount to its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying 
amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its 
fair value, goodwill is considered to be impaired and the goodwill balance is reduced by the difference between the fair 
value and carrying amount of the reporting unit.

We performed a qualitative assessment as of December 31, 2018 to determine whether it was more likely than not that
the fair value of the reporting unit was greater than the carrying value of the reporting unit. Based on these qualitative 
assessments, we determined that the fair value of the reporting unit was more likely than not greater than the carrying 
value of the reporting unit.

Estimates and assumptions used to perform the impairment evaluation are inherently uncertain and can significantly 
affect the outcome of the analysis. The estimates and assumptions we use in the annual goodwill impairment assessment 
included market participant considerations and future forecasted operating results. Changes in operating results and other 
assumptions could materially affect these estimates.

Impairment of Long-Lived Assets

We review long-lived assets for possible impairment when events or changes in circumstances indicate, in management’s
judgment, that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of
the carrying amount of an asset or asset group to its estimated undiscounted future cash flows expected to be generated 
by the asset or asset group. If the undiscounted cash flows are less than the carrying amount of the asset or asset group, 
an impairment loss is recognized for the amount by which the carrying amount of the asset or asset group exceeds its fair 
value.

31

Research and Development

The costs associated with research and development for the purpose of developing and improving new products are 
expensed  as  incurred.  For  the  years  ended  December  31,  2018,  2017,  and  2016  research  and  development  costs  
amounted to approximately $13.5 million, $13.0 million, and $12.0 million, respectively.

Advertising

Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2018, 2017, and 2016 
was approximately $0.8 million, $1.7 million, and $1.4 million, respectively.

Shipping and Handling

We incur shipping and handling costs in the distribution of products sold that are recorded in cost of sales. Shipping 
charges that are billed to the customer are recorded in revenues and as an expense in cost of sales. For the years ended 
December 31, 2018, 2017, and 2016 shipping and handling fees amounted to approximately $12.6 million, $11.4 million,
and $10.3 million, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. The Company recognizes deferred tax assets and
liabilities for the expected future tax consequences of temporary differences between the book carrying amounts and the 
tax basis of assets and liabilities. Excess tax benefits and deficiencies are reported as an income tax benefit or expense on 
the statement of income and are treated as discrete items to the income tax provision in the reporting period in which 
they occur.  We establish accruals for unrecognized tax positions when it is more likely than not that our tax return 
positions may not be fully sustained. The Company records a valuation allowance for deferred tax assets when, in the 
opinion of management, it is more likely than not that deferred tax assets will not be realized.

Share-Based Compensation

The Company recognizes expense for its share-based compensation based on the fair value of the awards that are 
granted. The Company’s share-based compensation plans provide for the granting of stock options and restricted stock. 
The fair values of stock options are estimated at the date of grant using the Black-Scholes-Merton option valuation 
model. The use of the Black-Scholes-Merton option valuation model requires the input of subjective assumptions. 
Measured compensation cost is recognized ratably over the vesting period of the related share-based compensation 
award. Forfeitures are accounted for as they occur. The fair value of restricted stock awards is determined based on the 
market value of the Company’s shares on the grant date and the compensation expense is recognized on a straight-line 
basis during the service period of the respective grant.

Derivative Instruments

In the course of normal operations, the Company occasionally enters into contracts such as forward priced physical 
contracts  for  the  purchase  of  raw  materials  that  qualify  for  and  are designated  as  normal  purchase  or  normal  sale 
contracts. Such contracts are exempted from the fair value accounting requirements and are accounted for at the time 
product is purchased or sold under the related contract. The Company does not engage in speculative transactions, nor 
does the Company hold or issue financial instruments for trading purposes.

Revenue Recognition

On  January  1,  2018,  we  adopted  the  new  accounting  standard  FASB  ASC  606, Revenue  from  Contracts  with 
Customers, and all the related amendments to all contracts using the retrospective method. The impact at adoption was 
not material to the consolidated financial statements. The new accounting policy provides results substantially consistent 
with prior revenue recognition policies.

The Company recognizes revenue when it satisfies the performance obligation in its contracts. Most of the Company’s
products  are  highly  customized,  cannot  be  resold  to  other  customers  and  the  cost  of  rework  to  be  resold  is  not 
economical. The Company has a formal cancellation policy and generally does not accept returns on these units. As a 
result, many of the Company’s products do not have an alternative use and therefore, for these products we recognize 

32

revenue over the time it takes to produce the unit. For all other products that are part sales or standardized units, we 
satisfy the performance obligation  when the title and risk  of ownership pass to the customer,  generally at time of 
shipment. Final sales prices are fixed based on purchase orders. Sales allowances and customer incentives are treated as 
reductions to sales and are provided for based on historical experiences and current estimates. Sales of our products are 
moderately seasonal with the peak period being July - November of each year.

In addition, the Company presents revenues net of sales tax and net of certain payments to our independent manufacturer 
representatives (“Representatives”). Representatives are national companies that are in the business of providing HVAC 
units and other related products and services to customers. The end user customer orders a bundled group of products 
and services from the Representative and expects the Representative to fulfill the order. Only after the specifications are 
agreed to by the Representative and the customer, and the decision is made to use an AAON HVAC unit, will we receive
notice of the order. We establish the amount we must receive for our HVAC unit (“minimum sales price”), but do not 
control the total order price that is negotiated by the Representative with the end user customer.

We are responsible for billings and collections resulting from all sales transactions, including those initiated by our 
Representatives. The Representatives submit the total order price to us for invoicing and collection. The total order price 
includes our  minimum sales  price and an additional amount  which  may include both the Representatives’ fee and 
amounts due for additional products and services required by the customer. These additional products and services may 
include controls purchased from another manufacturer to operate the unit, start-up services, and curbs for supporting the 
unit  (“Third  Party  Products”).  All  are  associated  with  the  purchase  of  a  HVAC  unit  but  may  be  provided  by  the 
Representative or another third party. The Company is under no obligation related to Third Party Products.

The Representatives’ fee and Third Party Products amounts (“Due to Representatives”) are paid only after all amounts 
associated with the order are collected from the customer. The amount of payments to our representatives was $47.8 
million, $51.8 million, and $55.0 million for each of the years ended December 31, 2018, 2017, and 2016, respectively.

The Company also sells extended warranties on parts for various lengths of time ranging from six months to 10 years.
Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately 
priced warranty period.

Insurance Reserves

Under the Company’s insurance programs, coverage is obtained for significant liability limits as well as those risks
required to be insured by law or contract. It is the policy of the Company to self-insure a portion of certain expected 
losses related primarily to workers’ compensation and medical liability. Provisions for losses expected under these
programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred.

Product Warranties

A provision is made for the estimated cost of maintaining product warranties to customers at the time the product is sold 
based upon historical claims experience by product line. The Company records a liability and an expense for estimated 
future  warranty  claims  based  upon  historical  experience  and  management’s  estimate  of  the  level  of  future 
claims. Changes in the estimated amounts recognized in prior years are recorded as an adjustment to the liability and 
expense in the current year.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at
the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting 
period. Because these estimates and assumptions require significant judgment, actual results could differ from those 
estimates  and  could  have  a  significant  impact  on  our  results  of  operations,  financial  position  and  cash  flows. We 
reevaluate  our  estimates  and  assumptions  as  needed,  but  at  a  minimum  on  a  quarterly  basis. The  most  significant 
estimates include, but are not limited to, the allowance for doubtful accounts, inventory reserves, warranty accrual, 
workers compensation accrual, medical insurance accrual, share-based compensation and income taxes. Actual results 
could differ materially from those estimates.

On  February  28,  2018,  we  closed  on  the  purchase  of  substantially  all  of  the  assets  of  WattMaster  Controls,  Inc., 
(“WattMaster”). The assets acquired consisted primarily of intellectual property, receivables, inventory and fixed assets.  
The Company also hired substantially all of the WattMaster employees.  These assets and workforce will allow us to 
accelerate the development of our own electronic controllers for air distribution systems. We funded the business 
combination with available cash of $6.0 million. In May 2018, we paid the final working capital settlement of $0.4 
million with available cash.  We have included the results of WattMaster’s operations in our consolidated financial 
statements beginning March 1, 2018.

The following table presents the allocation of the consideration paid to the assets acquired and liabilities assumed, based 
on their fair values, in the acquisition of WattMaster described above:

In connection with the closure of our Canadian facility on May 18, 2009, we sold land and a building in September 2010 
and assumed a note receivable from the borrower secured by the property. The C$1.1 million, 15 year note has an interest 
rate of 4.0% and is payable to us monthly, and has a C$0.6 million balloon payment due in October 2025. Interest 
payments are recognized in interest income.

We evaluate the note for impairment on a quarterly basis. We determine the note receivable to be impaired if we are
uncertain of its collectability based on the contractual terms. At December 31, 2018 and 2017, there was no impairment.

Our revolving credit facility, as amended, provides for maximum borrowings of $30.0 million which is provided by 
BOKF, NA dba Bank of Oklahoma (“Bank of Oklahoma”). Under the line of credit, there was one standby letter of credit 
totaling $1.3 million as of December 31, 2018. Borrowings available under the revolving credit facility at December 31, 
2018, were $28.7 million. Interest on borrowings is payable monthly at LIBOR plus 2.0%. No fees are associated with 
the unused portion of the committed amount. As of December 31, 2018 and 2017, we had no balance outstanding under 
our revolving credit facility. The revolving credit facility expires on July 26, 2021.  At December 31, 2018 and 2017, the 
weighted average interest rate was 4.2% and 3.5%, respectively.

37

At December 31, 2018, we were in compliance with our financial covenants. These covenants require that we meet 
certain parameters related to our tangible net worth and total liabilities to tangible net worth ratio. At December 31, 2018 
our tangible net worth was $247.5 million, which meets the requirement of being at or above $175.0 million. Our total 
liabilities to tangible net worth ratio was 0.2 to 1.0, which meets the requirement of not being above 2 to 1.

The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017.  Major changes under the Act include the 
following:
•
•
•
•

Reducing the corporate rate to 21 percent
Doubling bonus depreciation to 100 percent for five years
Further limitations on executive compensation deductions
Eliminating the domestic manufacturing deduction

As a result of these changes, the Company adjusted its deferred tax assets and liabilities in 2017 using the newly enacted
rates for the periods when they are expected to be realized.  The remeasurement in 2017 resulted in a benefit to income 
taxes of $4.4 million.  The new bonus depreciation provisions resulted in the Company taking $3.2 million of bonus 
depreciation in 2017.  The Company also has historically taken the domestic manufacturing deduction.  The Company 
will no longer receive the benefit of this deduction which typically has lowered our effective tax rate by 3.0%.

38

The Company sometimes has executive compensation that exceeds the $1.0 million limitation.  Typically the limit is 
exceeded due to the volume of stock activity performed by the executives during the year.  The limit could also be 
exceeded by the Chief Executive Officer receiving the maximum amount under our executive annual cash incentive 
bonus plan.  Any compensation that exceeded this limitation in 2018 and in the future will be a permanent difference and 
cause an increase to our income tax provision.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and 
liabilities for financial reporting purposes and the amount used for income tax purposes.

The significant components of the Company’s deferred tax assets and liabilities are as follows:

Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be 
recognized as a component of income tax expense.

14. Share-Based Compensation

On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (“LTIP”) which provided an additional 3.3 
million shares that could be granted in the form of stock options, stock appreciation rights, restricted stock awards, 
performance units and performance awards, in addition to the shares from the previous plan, the 1992 Plan. Since 
inception of the LTIP, non-qualified stock options and restricted stock awards have been granted with a five year vesting 
schedule. Under the LTIP, the exercise price of shares granted may not be less than 100% of the fair market value at the 
date of the grant.

On May 24, 2016, our stockholders adopted the 2016 Long-Term Incentive Plan (“2016 Plan”) which provides for 
approximately 6.4  million shares,  comprised  of 3.4  million new  shares  provided  for  under  the  2016  Plan, 
approximately 0.4 million shares that were available for issuance under the previous LTIP that are now authorized for 
issuance under the 2016 Plan, and an additional 2.6 million shares that were approved by the stockholders on May 15, 
2018. Under the 2016 Plan, shares can be granted in the form of stock options, stock appreciation rights, restricted stock 
awards, performance awards, dividend equivalent rights, and other awards. Under the 2016 Plan, the exercise price of 
shares granted may not be less than 100% of the fair market value at the date of the grant. The 2016 Plan is administered 
by the Compensation Committee of the Board of Directors or such other committee of the Board of Directors as is 
designated by the Board of Directors (the “Committee”). Membership on the Committee is limited to independent 
directors. The Committee may delegate certain duties to one or more officers of the Company as provided in the 2016 
Plan. The Committee determines the persons to whom awards are to be made, determines the type, size and terms of 

39

awards, interprets the 2016 Plan, establishes and revises rules and regulations relating to the 2016 Plan and makes any 
other determinations that it believes necessary for the administration of the 2016 Plan.

The total pre-tax compensation cost related to unvested stock options not yet recognized as of December 31, 2018 is 
$14.3 million and is expected to be recognized over a weighted-average period of 2.29 years.

The following weighted average assumptions were used to determine the fair value of the stock options granted on the 
original grant date for expense recognition purposes for options granted during December 31, 2018, 2017, and 2016 
using a Black Scholes-Merton Model:

The  expected  term  of  the  options  is  based  on  evaluations  of  historical  and  expected  future  employee  exercise 
behavior. The  risk-free  interest  rate  is  based  on  the  U.S.  Treasury  rates  at  the  date  of  grant  with  maturity  dates 
approximately equal to the expected life at the grant date. Volatility is based on historical volatility of our stock over time 
periods equal to the expected life at grant date.

The total intrinsic value of options exercised during the year ended December 31, 2018, 2017, and 2016 was $5.4 
million, $4.5 million, and $4.9 million, respectively. The cash received from options exercised during the year eneded 
December 31, 2018, 2017, and 2016 was $5.0 million, $2.3 million, and $2.1 million, respectively. The impact of these 
cash receipts is included in financing activities in the accompanying Consolidated Statements of Cash Flows.

Since 2007, as part of the LTIP and since May 2016 as part of the 2016 Plan, the Compensation Committee of the Board 
of Directors has authorized and issued restricted stock awards to directors and certain key employees. Restricted stock 
awards granted to directors vest one-third each year. All other restricted stock awards vest at a rate of 20% per year. The 
fair value of restricted stock awards is based on the fair market value of AAON common stock on the respective grant
dates, reduced for the present value of dividends.

41

These awards are recorded at their fair value on the date of grant and compensation cost is recorded using straight-line 
vesting over the service period. At December 31, 2018, unrecognized compensation cost related to unvested restricted 
stock awards was approximately $6.1 million which is expected to be recognized over a weighted average period of 1.84 
years.

Defined Contribution Plan - 401(k) - We sponsor a defined contribution plan (the “Plan”). Eligible employees may 
make  contributions  in  accordance  with  the  Plan  and  IRS  guidelines.  In  addition  to  the  traditional  401(k),  eligible 
employees are given the option of making an after-tax contribution to a Roth 401(k) or a combination of both. The Plan 
provides for automatic enrollment and for an automatic increase to the deferral percentage at January 1st of each year 
and each year thereafter. Eligible employees are automatically enrolled in the Plan at a 6% deferral rate and currently 
contributing employees deferral rates will be increased to 6% unless their current rate is above 6% or the employee elects 
to decline the automatic enrollment or increase.

42

The  Plan  was  amended  such  that  the  Company  matches  175%  up  to  6%  of  employee  contributions  of  eligible 
compensation.  Administrative expenses are paid for by Plan participants. Additionally, Plan participant forfeitures are 
used to reduce the cost of the Company contributions.

For the years ended December 31, 2018, 2017, and 2016 we made contributions of $8.1 million, $6.1 million, and $5.9 
million,  respectively.  The  Company  paid  no  administrative  expenses  for  the  years  ended  2018  and  2017  and 
approximately $0.04 million for the year ended 2016.

Profit Sharing Bonus Plan - We maintain a discretionary profit sharing bonus plan under which approximately 10% of 
pre-tax profit is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible 
employees are regular full-time employees who are actively employed and working on the first and last days of the 
calendar quarter and who were employed full-time for at least three full months prior to the beginning of the calendar 
quarter. Profit sharing expense was $6.2 million, $8.4 million, and  $9.0 million for the years ended December 31, 2018, 
2017, and 2016, respectively.

16. Stockholders’ Equity

Stock Repurchase - The Board has authorized three stock repurchase programs for the Company. The Company may
purchase shares on the open market from time to time, up to a total of 5.7 million shares. The Board must authorize the 
timing and amount of these purchases. Effective May 24, 2016, the Board authorized up to $25.0 million in open market 
repurchases and on June 2, 2016, the Company executed a repurchase agreement in accordance with the rules and 
regulations  of  the  SEC  allowing  the  Company  to  repurchase  an  aggregate  amount  of  $25.0  million  or  a  total  of 
approximately 2.0 million shares from the open market. The repurchase agreement expired on April 15, 2017. In May 
2018, the Board authorized up to $15.0 million in open market repurchases and on May 18, 2018, the Company executed 
a repurchase agreement in accordance with the rules and regulations of the SEC allowing the Company to repurchase 
shares from the open market. The agreement expires on March 1, 2019. The Company also has a stock repurchase 
arrangement by which employee-participants in our 401(k) savings and investment plan are entitled to have shares in 
AAON,  Inc.  stock  in  their  accounts  sold  to  the  Company.  The  maximum  number  of  shares  to  be  repurchased  is 
contingent upon the number of shares sold by employee-participants. Lastly, the Company repurchases shares of AAON, 
Inc. stock from certain of its directors and employees for payment of statutory tax withholdings on stock transactions. All 
other repurchases from directors or employees are contingent upon Board approval. All repurchases are done at current 
market prices.

We paid cash dividends of $16.7 million, $13.7 million, and $12.7 million in 2018, 2017, and 2016, respectively.

17. Commitments and Contingencies

We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor these 
claims and legal actions and frequently consult with our legal counsel to determine whether they may, when resolved, 
have a material adverse effect on our financial position, results of operations or cash flows and we accrue and/or disclose 
loss contingencies as appropriate. We have concluded that the likelihood is remote that the ultimate resolution of any 
pending litigation or claims will be material or have a material adverse effect on the Company’s business, financial
position, results of operations or cash flows.

We are occasionally party to short-term, cancellable and occasionally non-cancellable, fixed price contracts with major 
suppliers for the purchase of raw material and component parts. We expect to receive delivery of raw materials for use in
our manufacturing operations. These contracts are not accounted for as derivative instruments because they meet the 
normal  purchase  and  normal  sales  exemption.   At  December 31,  2018,  we  had one material  contractual  purchase 
obligation for approximately $2.2 million that expires in December 2019.

18. New Accounting Pronouncements

Changes  to  U.S.  GAAP  are  established  by  the  Financial  Accounting  Standards  Board  (“FASB”)  in  the  form  of 
accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification.

We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either 
not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The ASU will replace previous lease accounting 
guidance in U.S. GAAP.  The ASU requires the recognition of lease assets and lease liabilities by lessees for those leases 
classified as operating leases. The ASU retains a distinction between finance leases and operating leases. The ASU is 
effective for the Company beginning January 1, 2019.

The following ASUs have been issued in 2018 with the same effective dates and transition requirements:

•

•
•

•

ASU 2018-01, Land Easement Practical Expedient, which provides a relief from certain land easements held 
before the effective date.
ASU 2018-10, Leases: Codification Improvements, which provides clarification for various areas of Topic 842.
ASU 2018-11, Leases: Targeted Improvements, which provides clarification for several areas of Topic 842: 
comparative reporting requirements, an optional method of adoption (the transition method) and separating 
lease and non lease component for lessors.
ASU 2018-20, Leases: Narrow-Scope Improvement for Lessors, which provided clarification to lessors for sales 
taxes, variable payments and other costs.

The Company historically does not enter into numerous or material lease agreements to support its manufacturing 
operations. The Company typically enters into lease agreements that are less than a year and for leases on assets such as 
warehouse  vehicles  and  office  equipment. The  Company  assumed  a  multi-year  facility  lease  in  the  WattMaster 
acquisition. The  Company  has  completed  the  process  of  determining  our  contracts  to  which  this  new  guidance 
applies. The Company does not expect this new guidance to have a significant impact on the consolidated financial 
statements due to the non-material monetary amount of the total leased assets under the new applicable guidance.  
Furthermore, we have elected to apply the short-term lease accounting policy election to all short-term leases under the 

44

applicable guidance.  Under the policy election the lessee does not recognize a short-term lease liability or right-of-use 
asset on its balance sheet.

The Company will elect the transition method, which becomes effective upon the date of adoption of ASU 2016-02 
discussed above. The transition method allows entities to initially apply the new leases standard at the adoption date 
(January 1, 2019) and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the 
period of adoption.  We expect the cumulative-effect adjustments to the opening balance to be immaterial to the financial 
statements as a whole.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements: Changes to the Disclosure Requirement for 
Fair Value Measurements.  The ASU includes additional disclosure requirements for unrealized gains and losses for  
Level 3 fair value measurement and significant observable inputs used to develop Level 3 fair value measurements.  The 
ASU is effective for the Company beginning after December 15, 2019.  We do not expect ASU 2018-13 will have a 
material effect on our consolidated financial statements and notes thereto.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other. The ASU simplifies how an entity is 
required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a 
goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of 
that goodwill. We will be required to perform our annual goodwill impairment test by comparing the fair value of a 
reporting unit with its carrying amount. In the event the carrying amount exceeds the reporting unit’s fair value, a 
goodwill impairment charge for the excess will be recorded (not exceeding the recorded amount of the reporting unit’s
goodwill). The ASU  is  effective  for  the  Company  beginning April  1,  2020,  and  requires  a  prospective  method  of 
adoption, although early adoption is permitted for annual goodwill impairment tests performed on testing dates on or 
after January 1, 2017. We adopted this ASU effective January 1, 2018.

19. Earnings Per Share

Basic net income per share is calculated by dividing net income by the weighted average number of shares of common 
stock outstanding during the period. Diluted net income per share assumes the conversion of all potentially dilutive 
securities and is calculated by dividing net income by the sum of the weighted average number of shares of common 
stock outstanding plus all potentially dilutive securities. Dilutive common shares consist primarily of stock options and 
restricted stock awards.

The following table sets forth the computation of basic and diluted earnings per share:

Not Applicable.

Item 9A. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

At the end of the period covered by this Annual Report on Form 10-K, our management, under the supervision and with 
the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design 
and operation of our disclosure controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief 
Financial Officer believe that:

•

•

Our  disclosure  controls  and  procedures  are  designed  at  a  reasonable  assurance  threshold  to  ensure  that 
information required to be disclosed by us in the reports we file under the Securities Exchange Act of 1934 is 
recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms;
and

Our  disclosure  controls  and  procedures  operate  at  a  reasonable  assurance  threshold  such  that  important 
information flows to appropriate collection and disclosure points in a timely manner and are effective to ensure 
that such information is accumulated and communicated to our management, and made known to our Chief 

47

Executive Officer and Chief Financial Officer, particularly during the period when this Annual Report was 
prepared, as appropriate to allow timely decisions regarding the required disclosure.

Our Chief Executive Officer and Chief Financial Officer have evaluated our disclosure controls and procedures and 
concluded that these controls and procedures were effective as of December 31, 2018.

(b) Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. 
Our internal control over financial reporting is a process designed by, or under the supervision of, our principal executive 
and principal financial officer, and effected by our board of directors, management and other personnel, to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements  for 
external purposes in accordance with U.S. GAAP.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems 
determined to be effective can provide only reasonable assurance with respect to financial statement preparation and 
presentation.

In making our assessment of internal control over financial reporting, management has used the criteria issued by the 
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“COSO”)  in  the  2013  Internal  Control—
Integrated Framework. Based on our assessment, we believe that, as of December 31, 2018, our internal control over 
financial reporting is effective at the reasonable assurance level based on those criteria.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2018 has been audited 
by Grant Thornton LLP, our independent registered public accounting firm, as stated in their report which is included in 
this Item 9A of this report on Form 10-K.

(c) Changes in Internal Control over Financial Reporting

There have been no changes in internal control over financial reporting that occurred during the fourth quarter of 2018 
that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
AAON, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of AAON, Inc. (a Nevada corporation) and subsidiaries (the 
“Company”)  as  of  December  31,  2018,  based  on  criteria  established  in  the  2013  Internal  Control—Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).   In our 
opinion, the  Company  maintained, in all  material respects,  effective internal control over financial reporting as of 
December 31, 2018, based on criteria established in the 2013 Internal Control - Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 
31, 2018, and our report dated February 28, 2019, expressed an unqualified opinion on those financial statements.

Basis for opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s
Annual  Report  on  Internal  Control  over  Financial  Reporting.  Our  responsibility  is  to  express  an  opinion  on  the 
Company’s internal control over financial reporting based on our audit.  We are a public accounting firm registered with 
the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial 
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions  and  dispositions  of  the  assets  of  the  company;  (2)  provide  reasonable  assurance  that  transactions  are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely 
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the 
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.
