We continued to intensify our manufacturing effort to provide 

products which focus on energy efficiency and quality. Aided 

by the excellent response to the innovations recently 

introduced into our product lines, we posted a 

6.6% increase in total sales to $279.7 million 

from $262.5 million. Gross profits in 2008 

rose 17.1% to $67.2 million (24.0% of sales) 

compared to $57.4 million (21.9% of sales) 

in 2007. SG&A expenses increased 9.7%

operating margins improved to record 

levels as operating income climbed

Our  financial  condition  at  December  31,  2008,  remained 

strong. Total current assets were $80.1 million with a current 

ratio  of  2.0.  Despite  $9.6  million  of  capital  expenditures,  the 

repurchase of our common stock at a cost of $24.8 million, and 

dividend  payments  of  $5.8  million,  we  maintained  a  strong 

liquid position while having minimal long-term debt. In 1999

After the success of last year’s trial, we moved all employees to

During  the  test  period,  the  high-deductible  participants 

expended  significantly  less  per  participant  on  medical  care 

than did the other participants. Knowing that there was some

The  present  economic  environment  is  without  question  the 

most  restricted  we  have  witnessed  since  the  inception  of  the 

Company two decades ago. However, we remain quite positive 

regarding  the  Company’s  future  outlook.  Our  optimism  is 

based upon a number of factors. Specifically, we have expended 

the  capital,  time  and  labor  to  develop  a  product  line  which 

is  regarded  as  the  most  technologically  innovative  in  our 

business.  These  innovations,  which  directly  address  the  two 

major industry concerns, energy efficiency and environmental 

compatibility, have met with very positive response from our 

and  cooperation  of  our  customers,  sales  representatives  and 

shareholders as well as the loyalty of our dedicated employees, 

all of whose names appear at the end of this report.

geneRAl deVelopment And deSCRiption of buSineSS

AAON, Inc., a Nevada corporation, was incorporated on August 18, 1987.  Our subsidiaries include AAON, Inc., an Oklahoma 
corporation, AAON Coil Products, Inc., a Texas corporation, AAON Canada,  Inc., d/b/a Air Wise, an Ontario corporation and 
AAON  Properties, Inc., an Ontario corporation.   AAON Properties is the  lessor of property in Burlington, Ontario, Canada, to 
AAON Canada.  Unless the context otherwise requires, references in this Annual Report to “AAON,” the “Company”, “we,” “us,” “our” 
or “ours” refer to AAON, Inc., and our subsidiaries.

We are engaged in the manufacture and sale of air-conditioning and heating equipment.  Our products consist of both standardized 
and custom rooftop units, chillers, air-handling units, make-up air units, heat recovery units, condensing units, coils and boilers.

pRoduCtS And mARketS

Our products serve the commercial and industrial new construction and replacement markets.  To date virtually all of our sales have 
been to the domestic market.  Foreign sales accounted for less than 5% of our sales in 2008.

Our rooftop and condenser markets consist of units installed on commercial or industrial structures of generally less than 10 stories 
in height.  Our air-handling units, chillers, coils and boilers are applicable to 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.  Historically, approximately 
half of the industry’s market has consisted 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 6-18 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 2008 level of sales of $280 million, we estimate that we have a 13% share of the rooftop market and a 1% share of 
the coil market.  Approximately 54% of our sales now come from new construction and 46% from renovation/replacements.  The 
percentage of sales for new construction vs. replacement to particular customers is related to the customer’s stage of development.  
With the recent economic downturn and decrease in residential housing starts, the ratio of our sales between new construction and 
renovation/replacement could change.  Although the volatile economic conditions did not significantly affect our business in 2008, 
the impact the economy will have on us in 2009 is still unknown.

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, cooling and/or heat recovery components in a self-contained 
cabinet, referred to in the industry as “unitary” products.  Our other finished products are coils, air-handling units, condensing 
units, make-up air units, heat recovery units, and boilers.  Coils consist of a sheet metal casing with tubing and fins.  Air-handling 
units consist of coils, blowers and filters.  Condensing units consist of coils, fans and compressors, which, with the addition of a 
refrigerant-to-water heat exchanger, become chillers.  Make-up air units, heat recovery units and boilers consist of boilers and a sheet 
metal cabinet.

We offer five groups of rooftop units.  Our HB Series consisting of four cooling sizes ranging from two to five tons; our RM and RN 
Series offered in 21 cooling sizes ranging from two to 70 tons; our RL Series, which is offered in 15 cooling sizes ranging from 40 
to 230 tons; and our HA Series, which is a horizontal discharge package for either rooftop or ground installation, which we offer in 
eight sizes ranging from seven and one-half to 50 tons.  We also produce customized rooftop products with direct (MN Series) and 
indirect (DT Series) heating in sizes as required.

We also manufacture a Model LL chiller, which is available in both air-cooled condensing and evaporative cooled configurations.

Our air-handling units consist of the F1 and H/V Series, the modular (M2 and M3) Series and a customized NJ Series.  

AnnuAl RepoRt

Our heat recovery option applicable to our RM, RN and RL units, as well as our M2, M3 and NJ Series air handlers, respond 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.

Performance characteristics of our products range in cooling capacity from 28,000 - 4,320,000 BTU’s and in heating capacity from 
69,000 - 6,000,000 BTU’s.  All of our products meet the Department of Energy’s efficiency standards, which define the maximum 
amount of energy to be used in producing a given amount of cooling.

A typical commercial building installation requires a 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 have developed and are beginning to market a residential condensing unit (CB Series) and air handlers (F1 Series) as well as 
boilers (BL Series).  

mAjoR CuStomeRS

No customer accounted for 10% of our sales during 2008, 2007 or 2006.

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 increases in raw materials and purchased component prices on our profit margins by negotiating 
with each of our major suppliers on a term basis from six months to one year.  

diStRibution

We  employ  a  sales  staff  of  20  individuals  and  utilize  approximately  91  independent  manufacturer  representatives’  organizations 
having 106 offices to market our products in the United States and Canada.  We also have one international sales organization, which 
utilizes 12 distributors in other countries.  Sales are made directly to the contractor or end user, with shipments being made from our 
Tulsa, Oklahoma; Longview, Texas; and Burlington, Ontario, Canada plants to the job site.  Billings are to the contractor or end user, 
with a commission paid directly to the manufacturer representative.

Our products and sales strategy focus 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 106 sales offices and have 
factory service organizations at each of our plants.  Also, a number of the manufacturer representatives we utilize have their own 
service organizations, which, in connection with us, provide the necessary warranty work and/or normal service to customers.

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 gas-fired heat exchangers (if applicable); and 25 years on stainless 
steel heat exchangers (if applicable).

ReSeARCh And deVelopment

All of our R&D activities are company-sponsored, rather than customer-sponsored.  R&D has involved the HB, RM, RN, RL, NJ, 
DT and MN (rooftop units), F1, H/V, M2, M3 and NJ (air handlers), LL (chillers), CB (condensing units) and BL (boilers), as well as 
component evaluation and refinement, development of control systems and new product development.  We incurred research and 
development expenses of approximately $2,577,000, $2,483,000 and $1,974,000 in 2008, 2007 and 2006, respectively.

Part 108bACklog

Our current backlog as of March 1, 2009, was approximately $45,182,000 compared to approximately $51,365,000 at March 1, 2008.  
The current backlog consists of orders considered by management to be firm and substantially all of which will be filled by August 1, 
2009; however, the orders are subject to cancellation by the customers.

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 to 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 $15,150,000.  We believe that we will have sufficient funds available to meet our working 
capital needs for the foreseeable future.  We expect to renew our revolving credit agreement in July 2009.  We do not anticipate that 
the current situation in the credit market will impact our renewal.

SeASonAlity

Sales of our products are moderately seasonal with the peak period being July - November of each year.

Competition

In the standardized market, we compete primarily with Lennox International, Inc., Ingersoll Rand Limited, Johnson Controls Inc., 
Mestek Inc. and United Technologies Corporation.  All of these competitors are substantially larger and have greater resources than 
we do.  In the custom market, we compete with many larger and smaller manufacturers.  Our products compete on the basis of total 
value, quality, function, serviceability, efficiency, availability of product, product line recognition and acceptability of sales outlet.  
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 the business since quality and long-term cost are generally taken into account.

AnnuAl RepoRt

item 1A. RiSk fACtoRS. 

The following risks and uncertainties may affect our performance and results of operations.

ouR buSineSS CAn be huRt by the CuRRent eConomiC downtuRn.

Our business is affected by a number of economic factors, including the level of economic activity in the markets in which we operate.  
The current state of the United States economy has negatively impacted the commercial and industrial new construction markets.  
The current decline in economic activity in the United States could materially affect our financial condition and results of operations.  
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.  In the Heating, Ventilation, and Air Conditioning (“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 result in a decrease in our sales volume and profitability.

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.  We enter into cancelable and noncancelable contracts on terms from six months to one year 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 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 realize new technological advances in the HVAC industry.  Our inability to continue to successfully develop and market new 
products or our inability to achieve 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.

As of March 1, 2009, we had 1,303 permanent employees and 57 temporary employees.  The 53 employees of AAON Canada are 
represented by unions.  Management considers 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 heat recovery wheel option, blower, gas-fired heat exchanger and evaporative condenser desuperheater.

enViRonmentAl mAtteRS

Laws concerning the environment that affect or could affect our domestic 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 presently comply with these laws and that future compliance will 
not materially adversely affect our earnings or competitive position.

AVAilAble infoRmAtion

Our Internet website address is http://www.aaon.com.  Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current 
reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act of 
1934 will be available through our Internet website as soon as reasonably practical after we electronically file such material with, or 
furnish it to, the SEC.

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.

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, or could negatively affect our cash 
flow, 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.

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

Our stockholder rights plan and some provisions in our bylaws and Nevada law could delay or prevent a change in control, which 
could adversely affect the price of our common stock.

Despite our implementation of network security measures, our services are vulnerable to computer viruses, break-ins and similar

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.

The  plant  and  office  facilities  in  Tulsa,  Oklahoma,  consist  of  a  337,000  square  foot  building  (322,000  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 (the “original 
facility”), and a 563,000 square foot manufacturing/warehouse building and a 22,000 square foot office building (the “expansion 
facility”) located on a 40-acre tract of land across the street from the original facility (2440 South Yukon Avenue).  Both plants are 
of sheet metal construction.

The original facility’s manufacturing area is in a heavy industrial type building, with total coverage by bridge cranes, containing 
manufacturing equipment designed for sheet metal fabrication and metal stamping.  The manufacturing equipment contained in 
the original facility consists primarily of automated sheet metal fabrication equipment, supplemented by presses, press breaks and 
numerical control punching equipment.  Assembly lines consist of four cart-type conveyor lines with variable line speed adjustment, 
three of which are motor driven.  Subassembly areas and production line manning are based upon line speed.  The manufacturing 
facility is 1,140 feet in length and varies in width from 390 feet to 220 feet.  We use 22,000 sq. ft. for office space, 20,000 sq. ft. for 
warehouse space and 80,000 sq. ft. for two production lines; an additional 106,000 square feet is utilized for sheet metal fabrication.  
The remaining 357,000 sq. ft. (presently leased) will afford us additional plant space for long-term growth.  The expansion facility is  
39% (228,000 sq. ft.) utilized by us and 61% leased to a third party through May 31, 2009 at which time the facility will be remodeled 
to  give  us  increased  manufacturing  capacity.    The  2009  capital  expenditures  budget  reflects  the  projected  outlay  to  remodel  the 
facility.    

Our  operations  in  Longview,  Texas,  are  conducted  in  a  plant/office  building  at  203-207  Gum  Springs  Road,  containing  258,000 
sq. ft. on 14 acres.  The manufacturing area (approximately 251,000 sq. ft.) is located in three 120-foot wide sheet metal buildings 
connected by an adjoining structure.  The facility is built for light industrial manufacturing.  An additional, contiguous 15 acres were 
purchased in 2004 and 2005 for future expansion.

Our operations in Burlington, Ontario, Canada, are located at 279 Sumach Drive, consisting of an 82,000 sq. ft. office/manufacturing 
facility on a 5.6 acre tract of land.

Production at these facilities averaged approximately $23.3 million per month in 2008, which is approximately 67% of the estimated 
current production capacity.  Management deems our facilities to be nearly ideal for the type of products we manufacture.

On February 23, 2009, there were 1,003 holders of record, and approximately 2,000 beneficial owners, of our Common Stock.

On February 14, 2006, the Board of Directors voted to initiate a semi-annual cash dividend.  We initially paid Board of Director 
approved semi-annual dividends of $0.20 per share.  The Board of Directors approved future dividend payments of $0.16 per share 
related to the stock split effective August 21, 2007.  

In 2008, dividends were declared to shareholders of record at the close of business on June 12, 2008 and paid on July 3, 2008 and 
declared to shareholders of record at the close of business on December 12, 2008 and paid on January 2, 2009.  We paid cash dividends 
of approximately $5.8 million and declared dividends payable of approximately $2.8 million for the year ended December 31, 2008.  

Following repurchases of approximately 12% of our outstanding Common Stock between September 1999 and September 2001, 
we announced and began another stock repurchase program on October 17, 2002, targeting repurchases of up to approximately 
1,987,500 shares of our outstanding stock.  On February 14, 2006, the Board of Directors approved the suspension of our repurchase 
program. Through February 14, 2006, we had repurchased a total of 1,886,796 shares under this program for an aggregate price of 
$22,034,568, or an average of $11.68 per share.  We purchased the shares at the current market price.

On November 6, 2007, our Board of Directors authorized a new stock buyback program, targeting repurchases of up to approximately 
10% (1.8 million shares) of our outstanding stock from time to time in open market transactions. Through December 31, 2008, we 
repurchased a total of 1,692,258 shares under this program for an aggregate price of $33,710,939, or an average of $19.92 per share.   
We purchased the shares at the current market price.

On  July  1,  2005,  we  entered  into  a  stock  repurchase  arrangement  by  which  employee-participants  in  our  401(k)  savings  and 
investment plan are entitled to have shares of AAON stock in their accounts sold to us to provide diversification of their investments.  
The maximum number of shares to be repurchased is unknown under the program as the amount is contingent on the number of 
shares sold by employees. Through December 31, 2008, we repurchased 630,906 shares for an aggregate price of $10,102,687, or an 
average price of $16.01 per share.  We purchased the shares at the current market price.

AnnuAl RepoRt

On November 7, 2006, the Board of Directors authorized us to repurchase shares from certain Directors following their exercise 
of stock options.  The maximum number of shares to be repurchased is unknown under the program as the amount is contingent 
on the number of shares sold by Directors.  Through December 31, 2008, we repurchased 340,375 shares for an aggregate price of

Basic earnings per common share were computed by dividing net income by the weighted average number of shares of common 
stock outstanding during the reporting period.  Diluted earnings per common share were determined on the assumed exercise of 
dilutive options, as determined by applying the treasury stock method.  Effective August 21, 2007, we completed a three-for-two 
stock split.  The shares outstanding and earnings per share disclosures have been restated to reflect the stock split.

oVeRView

We engineer, manufacture and market air-conditioning and heating equipment consisting of standardized and custom rooftop units, 
chillers, air-handling units, make-up units, heat recovery units, condensing units, coils and boilers.  Custom units are marketed and 
sold to retail, manufacturing, educational, medical and other commercial industries.  We market units to all 50 states in the United 
States and certain provinces in Canada.  Foreign sales are less than 5% of our 2008 sales as the majority of all sales are domestic.  

We sell our products to property owners and contractors through a network of manufacturers’ representatives and our internal sales 
force.  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 6-18 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 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, which are 
obtained from domestic suppliers.  The raw materials market was volatile during 2008 due to the economic environment.  Raw 
materials pricing had steadily increased from the beginning of 2006 until the second half of 2008 when pricing sharply decreased.  
We experienced raw materials price increases of approximately 70% for steel, 18% for aluminum and 19% for copper from 2006 
through the second quarter of 2008.  Prices decreased by approximately 40% for steel, 76% for aluminum and 62% for copper from 
June 30, 2008 to December 31, 2008.  We attempt to limit the impact of price increases on these materials by entering cancelable and 
noncancelable fixed price contracts with our major suppliers for periods of 6 -12 months.    

Selling, general, and administrative (“SG&A”) costs include our internal sales force, warranty costs, profit sharing and administrative 
expense.  Warranty expense is estimated based on historical trends and other factors.  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 on compressors 
(if applicable); 15 years on gas-fired heat exchangers (if applicable); and 25 years on stainless steel heat exchangers (if applicable).  
Warranty charges on heat exchangers do not occur frequently.

Our office facilities consist of a 337,000 square foot building (322,000 sq. ft. of manufacturing/warehouse space and 15,000 sq. ft. of 
office space) located at 2425 S. Yukon Avenue, Tulsa, Oklahoma (the “original facility”), and a 563,000 square foot manufacturing/
warehouse building and a 22,000 square foot office building (the “expansion facility”) located across the street from the original 
facility at 2440 S. Yukon Avenue.  We utilize 39% of the expansion facility and the remaining 61% is leased to a third party. The third 
party lease expires May 31, 2009, at which time the facility will be remodeled to give us increased manufacturing capacity. The 2009 
capital expenditures budget reflects the projected outlay to remodel the facility.     

We conduct other operations in a plant/office building at 203-207 Gum Springs Road in Longview, Texas, containing 258,000 square 
feet (251,000 sq. ft. of manufacturing/warehouse and 7,000 sq. ft. of office space).  An additional 15 acres of land was purchased for 
future expansion in 2004 and 2005 in Longview, Texas. 

Our operations in Burlington, Ontario, Canada, are located at 279 Sumach Drive, consisting of an 82,000 sq. ft. office/manufacturing 
facility on a 5.6 acre tract of land.

ReSultS of opeRAtionS

Key events impacting our cash balance, financial condition, and results of operations in 2008 include the following:  

•  An  increase  in  the  volume  of  sales  on  all  product  lines  due  to  market  share  gains  and  effective  moderation  of  commodity 
costs  with  purchase  agreements  and  pricing  strategies  affecting  gross  margin,  resulted  in  significantly  higher  revenues  and 
net income.  The large volume of sales also lowered the effect of major fixed costs in general and administrative expenses and 
occupancy expenses.  

• We remained the leader in the industry for environmentally-friendly, energy efficient and quality innovations, utilizing R410A 
refrigerant and phasing out pollutant causing R22 refrigerant. The phase out of R22 began at the beginning of 2004.  We also utilize 
a high performance composite foam panel to eliminate over half of the heat transfer from typical fiberglass insulated panels.  We 
continue to utilize sloped condenser coils, and access compartments to filters, motor, and fans.  All of these innovations increase 
the demand for our products thus increasing market share.

• In February 2006, our Board of Directors initiated a program of semi-annual cash dividend payments.  Cash payments of $5.8 
million were made in 2008 ($2.9 million paid in January and July 2008, respectively), and $2.8 million was accrued as a liability 
for payment in January 2009.  

• Stock repurchases of our stock from employee’s 401(k) savings and investments plan was authorized in 2005. Stock repurchases 
of our stock from directors was authorized in 2006.  Stock repurchases of our stock from the open market was authorized and 
initiated in November 2007.   Total repurchases resulted in cash payments of $24.8 million.  This cash outlay is partially offset 
by cash received from options exercised by employees as a part of an incentive bonus program.  The cash received in 2008 from 
options exercised was $1.7 million.  

• Borrowings under the line of credit were $46.9 million and approximately $71,000 in interest expense was paid in 2008.  Borrowings 
under the line of credit where interest is accrued are relatively short and generally paid off within the month incurred or the 
following month.  At the end of 2008 there was $2.9 million outstanding on the line of credit.  

• Purchases of equipment and renovations to manufacturing facilities remained a priority. AAON’s capital expenditures were $9.6 
million.  Equipment purchases create significant efficiencies, lower production costs and allow continued growth in production.  
We currently estimate dedicating $7.0 million to $8.0 million to capital expenditures in 2009 for continued growth. 

Net sales were $279.7 million, $262.5 million and $231.5 million in 2008, 2007 and 2006, respectively.  Sales increased $17.2 million 
or 6.6% which was attributable to an increase in volume of product sold related to our new and redesigned products being favorably 
received by our customers, the diversified customer mix of products, active marketing by sales representatives and pricing strategies 
implemented in order to keep up with increasing raw material costs. The increase in sales in 2007 of $31.0 million or 13.4% was 
attributable to an increase in volume of product sold related to our new and redesigned products being favorably received by our 
customers, active marketing by sales representatives and pricing strategies implemented on 90% of our product lines in the second 
quarter in order to keep up with increasing raw material costs. New commercial construction steadily improved throughout 2007 
and 2006, contributing to growth of the market.  

gRoSS pRofit

Gross margins in 2008, 2007 and 2006 were $67.2 million, $57.4 million and $43.9 million, respectively.   As a percentage of sales, 
gross margins were 24.0%, 21.9% and 19.0% for the years ended 2008, 2007 and 2006.  The increase in gross profit for 2008, resulted 
from pricing strategies implemented and production and labor efficiencies, as sales volume increased. We saw a decrease in raw 
material costs in the second half of the year, which also contributed to higher gross profits.  Management anticipates the moderation 
of commodity costs through relationships with suppliers and price decreases in certain commodity costs, if realized, should enhance 
gross margins.  Due to an increase in the volume of sales, actual gross profit for 2008 increased by $9.8 million from 2007, and by 
$13.5 million from 2006 to 2007.

The principal high volume raw materials used in our manufacturing processes are steel, copper and aluminum, which are obtained 
from domestic suppliers. The raw materials market was volatile during 2008 due to the economic environment.  Raw materials pricing 
had steadily increased from the beginning of 2006 until the second half of 2008 when pricing sharply decreased.  We experienced 
raw materials price increases of approximately 70% for steel, 18% for aluminum and 19% for copper from 2006 through the second 
quarter of 2008.  Prices decreased by approximately 40% for steel, 76% for aluminum and 62% for copper from June 30, 2008 to 
December 31, 2008.  We attempt to limit the impact of price increases on these materials by entering cancelable and noncancelable 
fixed price contracts with our major suppliers for periods of 6 -12 months.    

We also purchase from other domestic manufacturers certain components, including compressors, electric motors and electrical 
controls used in our products. The suppliers of these components are significantly affected by the raw material costs as steel, copper 
and  aluminum  are  used  in  the  manufacturing  of  their  products.  While  raw  material  costs  decreased  in  the  last  half  of  the  year, 
increases in component parts were experienced throughout 2008. We instituted several price increases to customers from 2006 to 
2008 in an attempt to offset the continued increases in steel, copper, aluminum, and component parts. We attempt to limit the impact 
of price fluctuations on these materials by entering into cancelable and noncancelable fixed price contracts with our major suppliers 
for periods of 6-12 months. 

Selling, geneRAl And AdminiStRAtiVe expenSeS

Selling, general and administrative expenses were $23.8 million, $21.7 million and $18.1 million for the years ended 2008, 2007 and 
2006. The increase in selling, general and administrative expenses is due primarily to an increase in selling related expenses, warranty 
expense caused by increased sales, increase in profit sharing resulting from an increase in net income, and an overall increase in 
general  and  administrative  expenses.  In  2007,  the  increase  in  selling,  general  and  administrative  expenses  was  primarily  caused 
by an increase in sales expenditures for an increased sales force and active marketing, increases in salaries for selling, general and 
administrative personnel and an increase in profit sharing. There were additional non-cash compensation costs for the fair value of 
stock options granted to employees in accordance with the adoption of Statement of Financial Accounting Standards (“SFAS”) No. 
123R, Share-Based Payment (“SFAS 123R”).  

inteReSt expenSe

Interest expense was approximately $71,000, $10,000 and $81,000 for the years ended 2008, 2007 and 2006.  The increase in interest 
expense of approximately $61,000 in 2008 was due to higher average borrowings under the revolving credit facility as a result of 
a decrease in net cash provided by operations related to the stock repurchases.  The decrease in interest expense of approximately 
$71,000 from 2006 to 2007 was due to a decrease in average borrowings under the revolving credit facility and interest rates.  Interest 
on borrowings is payable monthly at the Wall Street Journal prime rate less 0.5% or LIBOR plus 1.6%, at our election (3.50% at 
December 31, 2008).  Average borrowings under the revolving credit facility are typically paid in full within the month of borrowing 
or the following month.

Cash Flows Used in Investing Activities. Cash flows used in investing activities were $9.6 million, $10.8 million and $16.8 million 
in 2008, 2007 and 2006, respectively.  The decrease in cash flows used in investing activities in 2008 and 2007 was $1.2 million and 
$6.0 million, respectively, and primarily related to a decrease in capital expenditures.  Management utilizes cash flows provided from 
operating activities to fund capital expenditures that are expected to increase growth and create efficiencies.  Due to anticipated 
production demands, we expect to expend approximately $7.0 million to $8.0 million in 2009 for a building expansion, a building 
renovation of the leased facility and equipment.  We expect the cash requirements to be provided from cash flows from operations.  
We did not invest in any certificates of deposits in 2008 and 2007, respectively.  A previously invested certificate of deposit matured 
in the first quarter of 2006.

Cash Flows Used in Financing Activities.  Cash flows used in financing activities were $24.5 million, $20.0 million and $3.3 million 
in 2008, 2007 and 2006, respectively.  The increase of cash used in financing activities primarily relates to cash dividends declared 
and paid and the continued repurchase of our stock.  

We occasionally utilize the revolving line of credit as described below in “General” to meet certain short-term cash demands based 
on our current liquidity at the time.  We have $2.9 million of borrowings outstanding under the line of credit at December 31, 2008.  
We had no net borrowings under the revolving line of credit at December 31, 2007.  We accessed $46.9 million and $12.1 million of 
borrowings under the line of credit during 2008 and 2007, respectively.  We utilized the revolving line of credit in 2006 for short-term 
demands in the amount of $53.7 million.

We received cash from stock options exercised of $1.7 million and $2.4 million and classified the excess tax benefit of stock options 
exercised and restricted stock awards vested of $1.6 million and $3.0 million in financing activities in 2008 and 2007, respectively.  
We received cash from stock options exercised for the year ended 2006 of approximately $1.3 million and classified the excess tax 
benefit of stock options exercised of $1.9 million.

We  repurchased  shares  of  stock  under  the  Board  of  Directors  authorized  stock  buyback  programs  in  2008,  2007  and  2006.    We 
repurchased shares of stock from employees’ 401(k) savings and investment plan, Directors, and the open market in 2008 in the 
amount of $24.8 million for 1,211,538 shares of stock.  We repurchased shares of stock from employees’ 401(k) savings and investment 
plan, Directors, and the open market in 2007 in the amount of $20.8 million for 1,082,736 shares of stock and in 2006 in the amount 
of $3.9 million for 250,500 shares of stock.  

On February 14, 2006, the Board of Directors voted to initiate a semi-annual cash dividend.  We initially  paid Board of Director 
approved semi-annual dividends of $0.20 per share.  The Board of Directors approved future dividend payments of $0.16 per share 
related to the stock split effective August 21, 2007.

Cash dividend payments of $5.8 million were made in 2008, and $2.8 million in dividends were declared and accrued as a liability 
in December 2008 for payment in January 2009.  Cash dividend payments of $5.0 million were made in 2007, and $2.9 million in 
dividends were declared and accrued as a liability in December 2007 for payment in January 2008.  Cash dividend payments of $2.5 
million were made in 2006, and $2.5 million in dividends were declared and accrued as a liability in December 2006 for payment in 
January 2007.  Board of Director approval is required to determine the date of declaration for each semi-annual payment.  

inteReSt inCome

Interest income was approximately $27,000, $8,000 and $24,000 in 2008, 2007 and 2006 respectively.  The increase in interest income 
is due to interest paid for repurchased stock shares that were held in transit by the transfer agent in early 2008.    

otheR inCome (expenSe)

Other  income  was  approximately  $724,000  in  2008.    Other  expense  was  approximately  $321,000  in  2007.    The  change  in  other 
income (expense) was primarily related to foreign currency losses that result from operations in Canada in 2008 and 2007.  Other 
income was approximately $424,000 in 2006.  Other income is attributable primarily to rental income from our expansion facility.  
All expenses associated with the facility that are allocated to the rental portion of the building are included in other income.  We plan 
to continue to rent the expansion facility until the lease term expires on May 31, 2009.  

impACt of CuRRent 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.  
The current state of the United States economy has negatively impacted the commercial and industrial new construction markets.  
The current decline in economic activity in the United States could materially affect our financial condition and results of operations.  
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.  In the Heating, Ventilation, and Air Conditioning (“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 result in a decrease in our sales volume and profitability. Although the volatile economic 
conditions did not significantly affect our business in 2008, the impact the economy will have on us in 2009 is still unknown.

AnAlySiS of 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.  

Cash  Provided  by  Operating  Activities.  Net  cash  provided  from  operating  activities  has  fluctuated  from  year  to  year.  Net  cash 
provided by operating activities was $33.4 million, $31.2 million and $19.4 million in fiscal years 2008, 2007 and 2006, respectively.  
The year-to-year variances are primarily from results of changes in net income, accounts receivable, inventories, accounts payable 
and accrued liabilities.  

Net income for fiscal year 2008 was $28.6 million, an increase of $5.4 million from 2007.  The increase in net income during fiscal 
years  2008  and  2007  compared  to  fiscal  years  2007  and  2006  was  primarily  due  to  increased  volume  of  sales,  adjusted  pricing 
strategies, fluctuations in raw materials costs, innovative and efficient products, and improved production efficiencies.  

Depreciation  expense  was  $9.4  million,  $9.7  million  and  $9.1  million  for  the  years  ended  December  31,  2008,  2007  and  2006, 
respectively.  The decrease in depreciation is due to the realization of full depreciation of certain capital assets. We adopted SFAS 
123R in 2006.  Share-based compensation was $0.8 million, $0.6 million and $0.5 million in 2008, 2007 and 2006, respectively.  Both 
depreciation expense and share-based compensation expense decreased net income but had no effect on operating cash.  

Accounts  receivable  balances  did  not  significantly  fluctuate  in  2008  even  though  sales  increased.    Accounts  receivable  increased 
during 2007 and 2006 from the increase in sales.  Accounts receivable increased by $0.9 million at December 31, 2008 compared to 
December 31, 2007.  The increase at December 31, 2007 from December 31, 2006 was $1.8 million. 

Inventories increased by $4.8 million, $2.1 million and $5.8 million at December 31, 2008, 2007 and 2006, respectively.  The increase 
in 2008 was attributable to procurement of inventory to accommodate an increase of sales. The leading factor in the increase in 2007 
and 2006 is primarily related to the valuation of inventories due to higher raw material and component parts costs.  

Accounts payable and accrued liabilities decreased by $1.3 million at December 31, 2008 and increased by $4.9 million and $4.3 
million at December 31, 2007 and 2006.  The decrease in 2008 is primarily due to timing of payments to vendors and a decrease in 
workers’ compensation expense. The increase  in 2007 is due to an increase in commissions payable related to the increase in sales, 
timing of commissions payable and payments to vendors.

Our  revolving  credit  facility  provides  for  maximum  borrowings  of  $15.2  million  which  is  provided  by  the  Bank  of  Oklahoma, 
National Association.  Under the line of credit, there is one standby letter of credit totaling $1.0 million.  The letter of credit is a 
requirement of our workers compensation insurance and was extended in 2008 and will expire on December 31, 2009.  Interest 
on borrowings is payable monthly at the Wall Street Journal prime rate less 0.5% or LIBOR plus 1.6%, at our election (3.50% at 
December 31, 2008).  No fees are associated with the unused portion of the committed amount.  

At  December  31,  2008,  we  had  $2.9  million  outstanding  under  the  revolving  credit  facility.    At  December  31,  2007,  we  had  no 
borrowings outstanding under the revolving credit facility.  Borrowings available under the revolving credit facility at December 31, 
2008, were $11.3 million.  At December 31, 2008 and 2007, we were in compliance with our financial ratio covenants.  The covenants 
are related to our tangible net worth, total liabilities to tangible net worth ratio and working capital.  At December 31, 2008 our 
tangible net worth was $96.5 million.  Our total liabilities to tangible net worth ratio was 2.2.  Our working capital was $40.6 million.  
On July 30, 2008, we renewed the line of credit with a maturity date of July 30, 2009.  We expect to renew our revolving credit 
agreement in July 2009.  We do not anticipate that the current situation in the credit market will impact our renewal.  

On July 12, 2007, our Board of Directors approved a three-for-two stock split of our outstanding stock for shareholders of record as 
of August 3, 2007.  The stock split was treated as a 50% stock dividend which was distributed on August 21, 2007.  As a result of the 
stock split, our Board of Directors adjusted the dividend paid per share to $0.16.  The applicable share and per share data for 2007 
and 2006 included herein has been restated to reflect the stock split 

Management believes projected cash flows from operations and our bank revolving credit facility (or comparable financing) will 
provide us the necessary liquidity and capital resources for fiscal year 2009 and the foreseeable future.  The belief that we will have 
the necessary liquidity and capital resources is based upon management’s knowledge of the HVAC industry and our place in that 
industry, our ability to limit our growth if necessary, our ability to authorize dividend cash payments, and our relationship with our 
existing bank lender.  For information concerning our revolving credit facility at December 31, 2008, see Note 3 to the Consolidated 
Financial Statements, Revolving Credit Facility.

1 Purchase  commitments  consist  primarily  of  copper  commitments.    In  the  normal  course  of  business  we  expect  to  purchase 
approximately $4.7 million of raw materials in the form of legally binding commitments.

The fixed rate interest on long-term debt includes the amount of interest due on our fixed rate long-term debt. These amounts do not 
include interest on our variable rate obligation related to the revolving credit facility.

We are a party to several short-term, cancelable and noncancelable, fixed price contracts with major suppliers for the purchase of 
raw material and component parts.

CRitiCAl ACCounting poliCieS 

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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, future 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 on a monthly basis. 

The following accounting policies may involve a higher degree of estimation or assumption:

Revenue  Recognition  –  We  recognize  revenues  from  sales  of  products  when  the  products  are  shipped  and  the  title  and  risk  of 
ownership pass to the customer.  Selling prices are fixed based on purchase orders or contractual agreements.  Sales allowances and 
customer incentives are treated as reductions to sales and are provided for based on historical experiences and current estimates.  
For sales initiated by independent manufacturer representatives, we recognize revenues net of the representatives’ commission.  Our 
policy is to record the collection and payment of sales taxes through a liability account.

Allowance for Doubtful Accounts – Our allowance for doubtful accounts is estimated to cover the risk of loss related to accounts 
receivable.   We establish an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, 
historical trends in collections and write-offs, current customer status, the age of the receivable, economic conditions and other 
information.  Aged receivables are reviewed on a monthly basis to determine if the reserve is adequate and adjusted accordingly 
at that time.  The evaluation of these factors involves complex, subjective judgments.  Thus, changes in these factors or changes in 
economic circumstances may significantly impact 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. The 
warranty period 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 on compressors (if applicable); 15 years on gas-fired heat exchangers (if applicable); and 25 years on stainless steel heat 
exchangers (if applicable).  Warranty expense is estimated based on the warranty period, historical warranty trends and associated 
costs, and any known identifiable warranty issue.   Warranty charges associated with heat exchanges do not occur frequently.  

15

16

08 
 
 
 
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.   

Medical Insurance – A provision is made for medical costs associated with our Medical Employee Benefit Plan, which is primarily 
a self-funded plan. A provision is made for estimated medical costs based on historical claims paid and potential significant future 
claims. The plan is supplemented by employee contributions and an excess policy for claims over $100,000 each.

Stock Compensation – We adopted SFAS 123R, effective January 1, 2006.  Applying this standard to value equity-based compensation 
requires us to use significant judgment and to make estimates, particularly for the assumptions used in the Black-Scholes valuation 
model, such as stock price volatility and expected option lives, as well as for the expected option forfeiture rates.  In accordance 
with SFAS 123R we measure the cost of employee services received in exchange for an award of equity instruments using the Black-
Scholes valuation model to calculate the grant-date fair value of the award.  The compensation cost is recognized over the period of 
time during which an employee is required to provide service in exchange for the award, which will be the vesting period.  

Historically, actual results have been within management’s expectations.

new ACCounting pRonounCementS

In September 2006, the FASB released SFAS No. 157, Fair Value Measurements (“SFAS 157”), which defines fair value and establishes 
a  framework  for  measuring  fair  value  in  generally  accepted  accounting  principles,  and  expands  disclosures  about  fair  value 
measurements.  Although SFAS 157 applies to (and amends) the provisions of existing authoritative literature, it does not, of itself, 
require any new fair value measurements or establish valuation standards.  SFAS 157 is effective for financial statements issued for 
fiscal years beginning after November 15, 2007, and interim periods within those fiscal years.  Adoption of SFAS 157 did not have a 
material impact on our Consolidated Financial Statements.

In February, 2007, the FASB issued FASB Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities 
(“SFAS  159”),  which  creates  an  alternative  measurement  treatment  for  certain  financial  assets  and  financial  liabilities.  SFAS  159 
permits fair value to be used for both the initial and subsequent measurements on an instrument by instrument basis, with changes 
in the fair value to be recognized in earnings as those changes occur. This election is referred to as the fair value option. SFAS 159 
also requires additional disclosures to compensate for the lack of comparability that will arise from the use of the fair value option. 
SFAS 159 is effective for fiscal years beginning after November 15, 2007.  The fair value option has not been elected for any financial 
assets or liabilities at December 31, 2008.

In December 2007, the FASB issued SFAS No. 141R, Business Combinations (“SFAS 141R”), which replaced FASB Statement 141, 
Business Combination, which changes the accounting for business combinations and noncontrolling interests. Among other things, 
when compared to the predecessor guidance SFAS 141R will require (i) more assets acquired and liabilities assumed to be measured 
at fair value as of the acquisition date, (ii) liabilities related to contingent consideration to be remeasured to fair value each subsequent 
reporting period, and (iii) acquirer in preacquisition periods to expense all acquisition-related costs. SFAS 141R must be applied 
prospectively for fiscal years beginning after December 15, 2008. We do not expect adoption of SFAS 141R to have a material impact 
on our Consolidated Financial Statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements – an Amendment 
of ARB No. 51 (“SFAS 160”), which changes the accounting and reporting for minority interests, which will be recharacterized as 
noncontrolling interests and classified as a component of equity.  SFAS 160 must be adopted no later than January 1, 2009.   We do 
not expect adoption of SFAS 160 to have a material impact on our Consolidated Financial Statements.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities – an Amendment 
of  FASB  Statement  No.  133  (“SFAS  161”),  which  requires  enhanced  disclosures  about  (i)  how  and  why  an  entity  uses  derivative 
instruments,  (ii)  how  derivative  instruments  and  related  hedged  items  are  accounted  for  under  SFAS  No.  133,  Accounting  for 
Derivative  Instruments  and  Hedging  Activities,  as  amended  (“SFAS  133”)  and  its  related  interpretations  and  (iii)  how  derivative 
instruments and related hedged items affect an entity’s financial position, financial performance and cash flows.  SFAS 161 will be 
effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008.  We do not expect 
adoption of SFAS 161 to have a material impact on our Consolidated Financial Statements.

AnnuAl RepoRt

In June 2008, the Emerging Issues Task Force (“EITF”) issued No. 03-6-1, Determining Whether Instruments Granted in Share-Based 
Payment Transactions Are Participating Securities (“EITF  03-6-1”), which addresses whether instruments granted in share-based 
payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings allocation in 
computing earnings per share (“EPS”) under the two-class method.  EITF 03-6-1 will be effective for financial statements issued for 
fiscal years beginning after December 15, 2008, and interim periods within those years.  All prior-period EPS data presented will be 
adjusted retrospectively to conform to the provisions of EITF 03-6-1. We are evaluating the expected impact of adoption of EITF 
03-6-1.

In December 2008, the FASB issued FSP No. FAS 132 R-1, Employers’ Disclosures about Postretirement Benefit Plan Assets (“FAS 132R-
1”), which provides guidance on an employer’s disclosures about plan assets of a defined benefit pension or other postretirement plan 
and requires employers to provide more transparency about the assets held by retirement plan and the concentrations of risk in those 
plans.  FAS 132 R-1 will be effective for fiscal years beginning after December 15, 2009.  We do not expect the adoption of FAS 132 
R-1 to have a material impact on our Consolidated Financial Statements.

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”, “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.  While the recent 
adverse economic climate has not yet impacted the business of AAON, there can be no assurances that economic conditions will not 
adversely affect our business in the future. 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.

We are subject to interest rate risk on our revolving credit facility, which bears variable interest based upon a prime or LIBOR rate.  
We had $2.9 million outstanding as of December 31, 2008.

Foreign  sales  accounted  for  less  than  approximately  5%  of  our  sales  in  2008  and  we  accept  payment  for  such  sales  in  U.S.  and 
Canadian dollars; therefore, we believe we are not exposed to significant foreign currency exchange rate risk on these sales.  Foreign 
currency transactions and financial statements are translated in accordance with SFAS No. 52, Foreign Currency Translation.  We 
use the U.S. dollar as our functional currency, except for the Canadian subsidiaries, which use the Canadian dollar.  Adjustments 
arising from translation of the Canadian subsidiaries’ financial statements are reflected in accumulated other comprehensive income.  
Transaction gains or losses that arise from exchange rate fluctuations applicable to transactions denominated in Canadian currency 
are included in the results of operations as incurred.  The exchange rate of the Canadian dollar to the United States dollar was $0.8196 
and $1.0193 at December 31, 2008 and 2007, respectively.

The principal high volume raw materials used in our manufacturing processes are steel, copper and aluminum, which are obtained 
from domestic suppliers. The raw materials market was volatile during 2008 due to the economic environment.  Raw materials pricing 
had steadily increased from the beginning of 2006 until the second half of 2008 when pricing sharply decreased.  We experienced 
raw materials price increases of approximately 70% for steel, 18% for aluminum and 19% for copper from 2006 through the second 
quarter of 2008.  Prices decreased by approximately 40% for steel, 76% for aluminum and 62% for copper from June 30, 2008 to 
December 31, 2008.  We attempt to limit the impact of price increases on these materials by entering cancelable and noncancelable 
fixed price contracts with our major suppliers for periods of 6 -12 months.  

We do not utilize derivative financial instruments to hedge our interest rate, foreign currency exchange rate or raw materials price 
risks.

that:

•    Our disclosure controls and procedures are designed 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  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 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.     

AAON’s 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, 2008.

(b) mAnAgement’S AnnuAl RepoRt on inteRnAl ContRol oVeR finAnCiAl RepoRting

The management of AAON, Inc. and our subsidiaries is responsible for establishing and maintaining adequate internal control over 
financial reporting. Our internal control system was designed to provide reasonable assurance to our management and Board of 
Directors regarding the preparation and fair presentation of published financial statements.

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 used the criteria issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework. Based on our assessment, 
we believe that, as of December 31, 2008, our internal control over financial reporting is effective based on those criteria.

Our independent registered public accounting firm has issued an attestation report on our internal control over financial reporting.

We have audited AAON, Inc. (a Nevada Corporation) and subsidiaries’ (collectively, the Company) internal control over financial 
reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated Framework issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO). 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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.

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.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 
31, 2008, based on criteria established in 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), the 
consolidated balance sheets of AAON, Inc. and subsidiaries as of December 31, 2008 and 2007, and the related consolidated statements 
of income, stockholders’ equity and comprehensive income, and cash flows for each of the three years in the period ended December 
31, 2008 and our report dated March 10, 2009 expressed an unqualified opinion on those consolidated financial statements.

(d) 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 2008 that have 
materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

tRAnSACtionS with RelAted peRSonS

Our  Code  of  Conduct  guides  the  Board  of  Directors  in  its  actions  and  deliberations  with  respect  to  related  party  transactions.  
Under the Code, conflicts of interest, including any involving the directors or any Named Officers, are prohibited except under any 
guidelines approved by the Board of Directors.  Only the Board of Directors may waive a provision of the Code of Conduct for a 
director or a Named Officer, and only then in compliance with all applicable laws and rules and regulations.  We did not enter into 
any new related party transactions and have no preexisting related party transactions in 2008 or 2007, respectively.    

diReCtoR independenCe

The  Board  of  Directors  (“Board”)  has  adopted  director  independence  standards  that  meet  and/or  exceed  listing  standards  set 
by  NASDAQ.    NASDAQ  has  set  forth  six  applicable  tests  and  requires  that  a  director  who  fails  any  of  the  tests  be  deemed  not 
independent.  In 2008, the Board affirmatively determined, considering the standards described more fully below, that Messrs. Short, 
Lackey, McElroy, and Stephenson are independent.  Upon the resignation of Mr. Pantaleoni, followed by the subsequent election 
of Mr. Levine, the Board affirmatively determined that Mr. Levine is independent. As a result of his position as our President, Mr. 
Asbjornson does not qualify as independent under the standards set forth below.  The Board has determined that Mr. Johnson should 
not be deemed independent, because he is a member of the law firm that serves as our General Counsel. In addition, each member 
of the Audit Committee and the Compensation Committee is independent.

AnnuAl RepoRt

Our director independence standards are as follows:

It is the policy of the Board that a majority of the members of the Board consist of directors independent of the Company and of our 
management.  For a director to be deemed “independent,” the Board shall affirmatively determine that the director has no material 
relationship with us or our affiliates or any member of the senior management or his or her affiliates.  In making this determination, 
the Board applies, at a minimum and in addition to any other standards for independence established under applicable statutes and 
regulations as outlined by the NASDAQ listing standards Rule 4200, the following standards, which it may amend or supplement 
from time to time:

•    A director who is, or has been within the last three years, an employee of the Company, or whose immediate family 
member is, or has been within the last three years a Named Officer, can not be deemed independent. Employment 
as an interim Chairman or Chief Executive Officer will not disqualify a director from being considered independent 
following that employment.

•    A director who has received, or who has an immediate family member who has received, during any twelve-month 
period  within  the  last  three  years,  more  than  $60,000  in  direct  compensation  from  us,  other  than  director  and 
committee fees and benefits under a tax-qualified retirement plan, or non-discretionary compensation for prior service 
(provided such compensation is not contingent in any way on continued service), can not be deemed independent. 
Compensation  received  by  a  director  for  former  service  as  an  interim  Chairman  or  Chief  Executive  Officer  and 
compensation received by an immediate family member for service as one of our non-executive employees will not be 
considered in determining independence under this test.

•    A director who (A) is, or whose immediate family member is, a current partner of a firm that is our external auditor; 
(B) is a current employee of such a firm; or (C) was, or whose immediate family member was, within the last three 
years (but is no longer) a partner or employee of such a firm and personally worked on our audit within that time can 
not be deemed independent.

•    A director who is, or whose immediate family member is, or has been within the last three years, employed as an 
executive officer of another company where any of our present Named Officers at the time serves or served on that 
company’s compensation committee can not be deemed independent.

•    A director who is a current employee or general partner, or whose immediate family member is a current executive 
officer or general partner, of an entity that has made payments to, or received payments from us for property or services 
in an amount which, in any of the last three fiscal years, exceeds the greater of $200,000 or 5% of such other entity’s 
consolidated gross revenues, other than payments arising solely from investments in our securities or payments under 
non-discretionary charitable contribution matching programs, can not be deemed independent.

For purposes of the independence standards set forth above, the terms:

•    “affiliate” means any of our consolidated subsidiaries and any other company or entity that controls, is controlled by 

or is under common control with us;

•    “executive officer” means an “officer” within the meaning of Rule 16a-1(f) under the Securities Exchange Act of 1934, 

as amended; and

•    “immediate family” means spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, 
brothers- and sisters-in-law and anyone (other than employees) sharing a person’s home, but excluding any person 
who is no longer an immediate family member as a result of legal separation or divorce, death or incapacitation.

21

22

Part 308The Board undertakes an annual review of the independence of all non-employee directors. In advance of the meeting at which this 
review occurs, each non-employee director is asked to provide the Board with full information regarding the director’s business and 
other relationships with us and our affiliates and with senior management and their affiliates to enable the Board to evaluate the 
director’s independence.

Directors have an affirmative obligation to inform the Board of any material changes in their circumstances or relationships that may 
impact their designation by the Board as “independent.” This obligation includes all business relationships between, on the one hand 
Directors or members of their immediate family, and, on the other hand, us and our affiliates or members of senior management and 
their affiliates, whether or not such business relationships are subject to any other approval requirements.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
AAON, Inc.

We have audited the accompanying consolidated balance sheets of AAON, Inc. (a Nevada corporation) and subsidiaries (collectively, 
the  Company)  as  of  December  31,  2008  and  2007,  and  the  related  consolidated  statements  of  income,  stockholders’  equity  and 
comprehensive income, and cash flows for each of the three years in the period ended December 31, 2008. These financial statements 
are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based 
on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures 
in  the  financial  statements.  An  audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by 
management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis 
for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position 
of AAON, Inc. and subsidiaries as of December 31, 2008 and 2007, and the results of their operations and their cash flows for each 
of the three years in the period ended December 31, 2008 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), AAON, 
Inc.’s internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control—Integrated 
Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO)  and  our  report  dated 
March 10, 2009 expressed an unqualified opinion thereon.

AAON, Inc. is a Nevada corporation which was incorporated on August 18, 1987.  Our subsidiaries include AAON, Inc., an Oklahoma 
corporation, AAON Coil Products, Inc., a Texas corporation, AAON Canada,  Inc., d/b/a Air Wise, an Ontario corporation and 
AAON Properties, Inc.,  an Ontario corporation.  AAON Properties is the  lessor of property in Burlington, Ontario, Canada, to 
AAON  Canada.   The  Consolidated  Financial  Statements  include  our  accounts  and  the  accounts  of  our  subsidiaries.    Unless  the 
context otherwise requires, references in this Annual Report to “AAON,” the “Company”, “we,” “us,” “our” or “ours” refer to AAON, 
Inc., and our subsidiaries.

We  are  engaged  in  the  manufacture  and  sale  of  air  conditioning  and  heating  equipment  consisting  of  standardized  and  custom 
rooftop units, chillers, air-handling units, make-up air units, heat recovery units, condensing units, coils and boilers. All significant 
intercompany accounts and transactions have been eliminated.

ReVenue ReCognition

We recognize revenues from sales of products when the products are shipped and the title and risk of ownership pass to the customer.  
Selling prices are fixed based on purchase orders or contractual agreements.  Sales allowances and customer incentives are treated 
as reductions to sales and are provided for based on historical experiences and current estimates.  For sales initiated by independent 
manufacturer representatives, we recognize revenues net of the representatives’ commission.  Our policy is to record the collection 
and payment of sales taxes through a liability account.

Common StoCk Split

On July 12, 2007, our Board of Directors approved a three-for-two stock split of the outstanding stock for shareholders of record as of 
August 3, 2007.  The stock split was treated as a 50% stock dividend which was distributed on August 21, 2007. The applicable share 
and per share data for 2007 and 2006 included herein has been restated to reflect the stock split.

CuRRenCy

Foreign currency transactions and financial statements are translated in accordance with Financial Accounting Standards Board 
(“FASB”) Statement No. 52, Foreign Currency Translation.  We use the U.S. dollar as our functional currency, except for the Canadian 
subsidiaries, which use the Canadian dollar. Adjustments arising from translation of the Canadian subsidiaries’ financial statements 
are reflected in accumulated other comprehensive income.  Transaction gains or losses that arise from exchange rate fluctuations 
applicable to transactions denominated in Canadian currency are included in the results of operations as incurred.

uSe of eStimAteS

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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, future 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 on a monthly basis.

The accompanying notes are an integral part of these statements.

The most significant estimates include the allowance for doubtful accounts, inventory reserves, warranty accrual, medical insurance 
accrual, and share-based compensation.  Actual results could differ materially from those estimates.  

Inventory balances at December 31, 2008 and 2007, and the related changes in the allowance for excess and obsolete inventories for 
the three years ended December 31, 2008, 2007 and 2006, are as follows:

AnnuAl RepoRt

ConCentRAtionS

Our customers are concentrated primarily in the domestic commercial and industrial new construction and replacement markets.  
To date, virtually all of our sales have been to the domestic market, with foreign sales accounting for less than 5% of revenues in 
2008.  No customer accounted for 10% of our sales during 2008, 2007 or 2006 or more than 5% of our accounts receivable balance 
at December 31, 2008 or 2007.

CASh And CASh equiVAlentS

Cash and cash equivalents consist of bank deposits and highly liquid, interest-bearing money market funds with initial maturities of 
three months or less.

ACCountS ReCeiVAble

We grant credit to our customers and perform ongoing credit evaluations.  We generally do not require collateral or charge interest.  
We establish an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical 
trends,  economic  and  market  conditions  and  the  age  of  the  receivable.    Past  due  accounts  are  generally  written  off  against  the 
allowance for doubtful accounts only after all collection attempts have been exhausted.

We evaluate long-lived assets for impairment when events or changes in circumstances indicate, in management’s judgment, that 
the carrying value of such assets may not be recoverable.  When an indicator of impairment has occurred, management’s estimate of 
undiscounted cash flows attributable to the assets is compared to the carrying value of the assets to determine whether impairment 
has  occurred.    If  an  impairment  of  the  carrying  value  has  occurred,  the  amount  of  the  impairment  recognized  in  the  financial 
statements is determined by estimating the fair value of the assets and recording a loss for the amount that the carrying value exceeds 
the estimated fair value. Management determined no impairment was required during 2008, 2007 and 2006.

CommitmentS And ContRACtuAl AgReementS

Inventories are valued at the lower of cost or market.  Cost is determined by the first-in, first-out (“FIFO”) method.  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.

We are a party to several short-term, cancelable and noncancelable, fixed price contracts with major suppliers for the purchase of raw 
material and component parts. During 2009, in the normal course of business we expect to purchase approximately $4.7 million of 
copper in the form of legally binding commitments.

A provision is made for estimated warranty costs at the time the related products are sold based upon the warranty period, historical 
trends, new products and any known identifiable warranty issues.  Warranty expense was $4.0 million, $4.0 million and $2.4 million 
for the years ended December 31, 2008, 2007 and 2006, respectively.

In 2007, the provision for warranties was increased due to an extension in the warranty period.  In 2006, the provision for warranties 
was decreased due to a change in estimate related to preexisting warranties occurring in the fourth quarter of 2006.  The change in 
estimate was due to factors stated above, such as current information on historical trends and a reduction in identifiable warranty 
issues.

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.

We  maintain  a  discretionary  profit  sharing  bonus  plan  under  which  10%  of  pre-tax  profit  at  each  subsidiary  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 day of the calendar quarter and remain continuously, actively employed and working 
on the last day of the quarter and who work at least 80% of the quarter. Profit sharing expense was $5.1 million, $4.2 million and $3.3 
million for the years ended December 31, 2008, 2007 and 2006, respectively.

defined ContRibution plAn - 401(k)   

 We sponsor a defined contribution benefit plan (“the Plan”). Eligible employees may make contributions in accordance with the Plan 
and IRS guidelines.  In addition, effective May 30, 2005, the Plan was amended to provide for automatic enrollment and provided for 
an automatic increase to the deferral percent at January 1st of each year and each year thereafter, unless the employee elects to decline 
the automatic increase and enrollment. Beginning with pay periods after May 30, 2005, the one year enrollment waiting period was 
waived.  Administrative expenses we paid for the plan were approximately $93,000, $98,000 and $85,000 for the years ended 2008, 
2007 and 2006, respectively.

After January 1, 2007, our matching increased to 50% of the employee’s salary deferral up to the first 9% of compensation.  From 
January 1, 2006 to December 31, 2006, we matched 50% of the employee’s salary deferral up to the first 7% of compensation.  We 
contribute in the form of cash and direct the investment to shares of AAON Stock.  No other purchases of AAON stock are permitted. 
Employees are 100% vested in salary deferral contributions and vest 20% per year at the end of years two through six of employment 
in employer matching contributions.  We made matching contributions of $1.4 million, $1.3 million and $1.0 million in 2008, 2007 
and 2006, respectively.

In September 2006, the FASB released SFAS No. 157, Fair Value Measurements (“SFAS 157”), which defines fair value and establishes 
a  framework  for  measuring  fair  value  in  generally  accepted  accounting  principles,  and  expands  disclosures  about  fair  value 
measurements.  Although SFAS 157 applies to (and amends) the provisions of existing authoritative literature, it does not, of itself, 
require any new fair value measurements or establish valuation standards.  SFAS 157 is effective for financial statements issued for 
fiscal years beginning after November 15, 2007, and interim periods within those fiscal years.  Adoption of SFAS 157 did not have a 
material impact on our Consolidated Financial Statements.

In February, 2007, the FASB issued FASB Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities 
(“SFAS  159”),  which  creates  an  alternative  measurement  treatment  for  certain  financial  assets  and  financial  liabilities.  SFAS  159 
permits fair value to be used for both the initial and subsequent measurements on an instrument by instrument basis, with changes 
in the fair value to be recognized in earnings as those changes occur. This election is referred to as the fair value option. SFAS 159 
also requires additional disclosures to compensate for the lack of comparability that will arise from the use of the fair value option. 
SFAS 159 is effective for fiscal years beginning after November 15, 2007.  The fair value option has not been elected for any financial 
assets or liabilities at December 31, 2008.

In December 2007, the FASB issued SFAS No. 141R, Business Combinations (“SFAS 141R”), which replaced FASB Statement 141, 
Business Combinations, which changes the accounting for business combinations and noncontrolling interests. Among other things, 
when compared to the predecessor guidance SFAS 141R will require (i) more assets acquired and liabilities assumed to be measured 
at fair value as of the acquisition date, (ii) liabilities related to contingent consideration to be remeasured to fair value each subsequent 
reporting period, and (iii) acquirer in preacquisition periods to expense all acquisition-related costs. SFAS 141R must be applied 
prospectively for fiscal years beginning after December 15, 2008. We do not expect adoption of SFAS 141R to have a material impact 
on our Consolidated Financial Statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements - an Amendment 
of ARB No. 51 (“SFAS 160”), which changes the accounting and reporting for minority interests, which will be recharacterized as 
noncontrolling interests and classified as a component of equity.  SFAS 160 must be adopted by us no later than January 1, 2009.   We 
do not expect adoption of SFAS 160 to have a material impact on our Consolidated Financial Statements.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities - an Amendment 
of  FASB  Statement  No.  133  (“SFAS  161”),  which  requires  enhanced  disclosures  about  (i)  how  and  why  an  entity  uses  derivative 
instruments,  (ii)  how  derivative  instruments  and  related  hedged  items  are  accounted  for  under  SFAS  No.  133,  Accounting  for 
Derivative  Instruments  and  Hedging  Activities,  as  amended  (“SFAS  133”)  and  its  related  interpretations  and  (iii)  how  derivative 
instruments and related hedged items affect an entity’s financial position, financial performance and cash flows.  SFAS 161 will be 
effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008.  We do not expect 
adoption of SFAS 161 to have a material impact on our Consolidated Financial Statements.

In June 2008, the Emerging Issues Task Force (“EITF”) issued No. 03-6-1, Determining Whether Instruments Granted in Share-Based 
Payment Transactions Are Participating Securities (“EITF  03-6-1”), which addresses whether instruments granted in share-based 
payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings allocation in 
computing earnings per share (“EPS”) under the two-class method.  EITF 03-6-1 will be effective for financial statements issued for 
fiscal years beginning after December 15, 2008, and interim periods within those years.  All prior-period EPS data presented will be 
adjusted retrospectively to conform to the provisions of EITF 03-6-1. We are evaluating the expected impact of adoption of EITF 
03-6-1.

In December 2008, the FASB issued FSP No. FAS 132 R-1, Employers’ Disclosures about Postretirement Benefit Plan Assets (“FAS 
132R-1”), which provides guidance on an employer’s disclosures about plan assets of a defined benefit pension or other postretirement 
plan and requires employers to provide more transparency about the assets held by retirement plan and the concentrations of risk in 
those plans.  FAS 123 R-1 will be effective for fiscal years beginning after December 15, 2009.  We do not expect the adoption of FAS 
132 R-1 to have a material impact on our Consolidated Financial Statements.

SegmentS

Management has reviewed our business operations and determined that we have two operating segments as defined in SFAS 131, 
Disclosures about Segments of an Enterprise and Related Information (“SFAS 131”).  We have a domestic and foreign operating 
segment.    The  domestic  operating  segment  includes  the  operations  of  AAON,  Inc.  and  AAON  Coil  Products,  Inc.    The  foreign 
operating segment includes the operations of AAON Canada and AAON Properties.  Management has determined that the foreign 
operating segment does not constitute a separate reporting segment based on the quantitative threshold tests of SFAS 131.  We sell 
similar products with similar economic characteristics to similar classes of customers.  The technologies and operations are highly 
integrated.  Revenues and costs are reviewed monthly by management on a product line basis as a single business segment.   

2. SupplementAl CASh flow infoRmAtion

Interest payments of approximately $71,000, $10,000 and $81,000 were made during the years ended December 31, 2008, 2007 and 
2006, respectively.  Payments for income taxes of $12.7 million, $10.2 million and $6.5 million were made during the years ended 
December 31, 2008, 2007 and 2006, respectively. Dividends payable of $2.8 million and $2.9 million were accrued as of December 
31, 2008 and 2007 and paid on January 3, 2009 and 2008, respectively.

The tax effect of temporary differences giving rise to our deferred income taxes at December 31 is as follows:

AnnuAl RepoRt

Our revolving credit facility provides for maximum borrowings of $15.2 million which is provided by the Bank of Oklahoma, National 
Association.  Under the line of credit, there is one standby letter of credit totaling $1.0 million.  The letter of credit was a requirement 
of our workers compensation insurance and has been renewed and will expire December 31, 2009.  Interest on borrowings is payable 
monthly at the Wall Street Journal prime rate less 0.5% or LIBOR plus 1.6%, at our election (3.50% at December 31, 2008).  No fees 
are associated with the unused portion of the committed amount.  

At December 31, 2008, we had $2.9 million borrowed under the revolving credit facility.  We had no borrowings outstanding under 
the revolving credit facility at December 31, 2007.  Borrowings available under the revolving credit facility at December 31, 2008, 
were $11.3 million.  At December 31, 2008 and 2007, we were in compliance with our financial ratio covenants. The covenants are 
related to our tangible net worth, total liabilities to tangible net worth ratio and working capital.  At December 31, 2008 our tangible 
net worth was $96.5 million.  Our total liabilities to tangible net worth ratio was 2.2.  Our working capital was $40.6 million.  On July 
30, 2008, we renewed the line of credit with a maturity date of July 30, 2009.  We expect to renew our revolving credit agreement in 
July 2009.  We do not anticipate that the current situation in the credit market will impact our renewal.    

4. debt

Short-term debt at December 31, 2008 and 2007 consisted of notes payable totaling approximately $91,000 due in 2009 and 2008, 
respectively.  In 2008 and 2007, respectively, the notes payable are due in monthly installments of $7,588, with an interest rate of 
4.148%, related to a computer capital lease.   

5. inCome tAxeS

We follow the liability method of accounting for income taxes, which provides that deferred tax liabilities and assets are based on the 
difference between the financial statement and income tax bases of assets and liabilities using currently enacted tax rates.

The total net operating loss (“NOL”) deferred tax asset of approximately $2.3 million relates to AAON Canada.  The NOL’s originating 
in 2008, 2007 and 2006 will expire in twenty years, nineteen years and eighteen years, respectively.  The NOL’s originating in 2005 
will expire in 7 years.

We file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions.  Effective January 1, 2007, we 
adopted FIN 48.

The total amount of unrecognized tax benefits is as follows:

The total amount of unrecognized tax benefits that if recognized would impact the effective tax rate is approximately $50,000.

We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense.  At December 31, 2008 and 
2007, we had accrued approximately $6,000 and $110,000 for the potential payment of interest and penalties, respectively.

The total amount of unrecognized tax benefits at December 31, 2008 is approximately $50,000 related to tax positions for which it is 
reasonably possible that the total amounts could significantly decrease during the next twelve months.  This amount represents the 
unrecognized tax benefits comprised of items related to determination of state nexus and intercompany charges.  Resolution of these 
tax benefits will occur during the year ending December 31, 2009.  As of December 31, 2008, we are subject to U.S. Federal income 
tax examinations for the tax years 2005 through 2008, and to non-U.S. income tax examinations for the tax years of 2005 through 
2008.  In addition, we are subject to state and local income tax examinations for the tax years 2004 through 2008.

6. ShARe-bASed CompenSAtion

We have historically maintained a stock option plan for key employees, directors and consultants (“the 1992 Plan”).  The 1992 plan 
provided for 4.4 million shares of common stock to be issued under the plan.  Under the terms of the plan, the exercise price of shares 
granted may not be less than 85% of the fair market value at the date of the grant.  Options granted to directors prior to May 25, 2004, 
vest one year from the date of grant and are exercisable for nine years thereafter.  Options granted to directors on or after May 25, 
2004, vest one-third each year, commencing one year after the date of grant.  All other options granted vest at a rate of 20% per year, 
commencing one year after date of grant, and are exercisable during years 2-10. 

On  May  22,  2007,  our  stockholders  adopted  a  Long-Term  Incentive  Plan  which  provides  an  additional  750,000  shares  that  can 
be  granted  in  the  form  of  stock  options,  stock  appreciation  rights,  restricted  stock  awards,  performance  units  and  performance 
awards.  Since inception of the Plan, non-qualified stock options and restricted stock awards have been granted with the same vesting 
schedule as the previous plan.  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.

We apply the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123R Share-Based Payment (“SFAS 123R”).  
The compensation cost is based on the grant date fair value of stock options issued calculated using a Black-Scholes-Merton Option 
Pricing Model, or the grant date fair value of a restricted share less the present value of dividends, in accordance with the provisions 
of SFAS 123R.

We  recognized  approximately  $400,000  and  $526,000  for  the  year  ended  December  31,  2008  and  2007,  respectively,  in  pre-tax 
compensation expense related to stock options in the Consolidated  Statements of Income.  The total pre-tax compensation cost 
related to unvested stock options not yet recognized as of December 31, 2008 is $1.1 million and is expected to be recognized over a 
weighted-average period of 2.1 years. 

The following assumptions were used to determine the fair value of the unvested stock options on the original grant date for expense 
recognition purposes for options granted during the years ended December 31, 2008, 2007 and 2006:

Directors and Officers:

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.   We initiated a dividend payout in the second quarter of 2006. We 
initially used the Board of Director approved semi-annual dividends of $0.20 per share through July 3, 2007 to calculate the expected 
dividend yield.  The Board of Directors approved future dividend payments of $0.16 per share related to the stock split effective 
August 21, 2007 and the table above was adjusted to reflect the change.

intrinsic value of options exercised during the year ended December 31, 2008 and 2007 was $6.4 million and $8.7 million, respectively.  
The cash received from options exercised during the year ended December 31, 2008 and 2007 was $1.7 million and $2.4 million, 
respectively.  The impact of these cash receipts is included in financing activities in the accompany Consolidated Statements of Cash

The total fair value of shares vested during the year ended December 31, 2008 was approximately $577,000.   

During 2007, the Compensation Committee of the Board of Directors authorized and issued restricted stock awards to key employees 
and directors. The restricted stock award program offers the opportunity to earn shares of AAON Common Stock over time, rather 
than options that give the right to purchase stock at a set price.  Restricted stock awards granted to directors vest one-third each year.  
All other restricted stock awards vest at a rate of 20% per year.  Restricted stock awards are grants that entitle the holder to shares of 
common stock subject to certain terms.  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.

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.  The weighted average grant date fair value of restricted stock awards granted during 2008 and 2007 was $19.34 
and $20.85 per share, respectively. We recognized approximately $350,000 and $56,000 for the year ended December 31, 2008 and 
2007, respectively in pre-tax compensation expense related to restricted stock awards in the Consolidated Statements of Income.  In 
addition, as of December 31, 2008, unrecognized compensation cost related to unvested restricted stock awards was approximately 
$685,000 which is expected to be recognized over a weighted average period of 1.7 years.

A summary of the unvested restricted stock awards for the year ended December 31, 2008, is as follows:

SFAS 123R requires that cash flows from the exercise of stock options resulting from tax benefits in excess of recognized cumulative 
compensation costs be classified as financing cash flows.  For the twelve months ended December 31, 2008 and 2007, the excess tax 
benefits of stock options exercised and restricted stock awards vested was $1.6 million and $3.0 million respectively. 

AnnuAl RepoRt

7. StoCkholdeR RightS plAn

During 1999, the Board of Directors adopted a Stockholder Rights Plan (the “Plan”), which was amended in 2002.  Under the Plan, 
stockholders of record on March 1, 1999, received a dividend of one right per share of our Common Stock.  Stock issued after March 
1, 1999, contains a notation incorporating the rights.  Each right entitles the holder to purchase one one-thousandth (1/1,000) of 
a share of Series A Preferred Stock at an exercise price of $90.  The rights are traded with our Common Stock.  The rights become 
exercisable after a person has acquired, or a tender offer is made for, 15% or more of our Common Stock.  If either of these events 
occurs, upon exercise the holder (other than a holder owning more than 15% of the outstanding stock) will receive the number of 
shares of our Common Stock having a market value equal to two times the exercise price.

The rights may be redeemed by us for $0.001 per right until a person or group has acquired 15% of our Common Stock.  The rights 
expire on August 20, 2012.

8. StoCk RepuRChASe

Following  repurchases  of  approximately  12%  of  our  outstanding  common  stock  between  September  1999  and  September  2001, 
we announced and began another stock repurchase program on October 17, 2002, targeting repurchases of up to an additional 2.0 
million shares of our outstanding stock.  On February 14, 2006, the Board of Directors approved the suspension of our repurchase 
program.  Through February 14, 2006, we had repurchased a total of 1,886,796 shares under this program for an aggregate price of 
$22,034,568, or an average of $11.68 per share.  We purchased the shares at the then current market price.

On  November  6,  2007,  we  began  a  new  stock  buyback  program,  targeting  repurchases  of  up  to  approximately  10%  (1.8  million 
shares) of our outstanding stock from time to time in open market transactions.  Through December 31, 2008, we had repurchased 
a total of 1,692,258 shares under this program for an aggregate price of $33,710,939, or an average price of $19.92 per share.    We 
purchased the shares at the current market price.  

On July 1, 2005, we entered into a stock repurchase arrangement by which employee participants in AAON’s 401(k) savings and 
investment plan are entitled to have shares of AAON stock in their accounts sold to us to provide diversification of their investments.  
The maximum number of shares to be repurchased is unknown under the program as the amount is contingent on the number of 
shares sold by employees. Through December 31, 2008, we repurchased 630,906 shares for an aggregate price of $10,102,687, or an 
average price of $16.01 per share. We purchased the shares at the current market price.

On November 7, 2006, the Board of Directors authorized us to repurchase shares from certain directors following their exercise 
of stock options.  The maximum number of shares to be repurchased is unknown under the program as the amount is contingent 
on the number of shares sold by directors.  Through December 31, 2008, we repurchased 340,375 shares for an aggregate price of 
$6,957,423, or an average price of $20.44 per share.  We purchased the shares at the current market price.

9. diVidendS

On February 14, 2006, the Board of Directors voted to initiate a semi-annual cash dividend.  We initially paid Board of Director 
approved semi-annual dividends of $0.20 per share.  The Board of Directors approved future dividend payments of $0.16 per share 
related to the stock split effective August 21, 2007. 

Dividends were declared to shareholders of record at the close of business on June 12, 2008 and December 12, 2008 and paid on 
July 3, 2008 and January 2, 2009.  We paid cash dividends of $5.8 million and declared dividends payable of $2.8 million for the year 
ended December 31, 2008.  Cash dividend payments of $5.0 million were made in 2007, and $2.9 million in dividends were declared 
and accrued as a liability in December 2007 for payment in January 2008.
