General Development and Description of Business AAON, Inc., a Nevada corporation, was incorporated on August 18, 1987. The Company (including its subsidiaries) is 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 and coils. Products and Markets The Company's products serve the commercial and industrial new construction and replacement markets. To date virtually all of the Company's sales have been to the domestic market, with foreign sales accounting for only 2% of its sales in 2004. The rooftop and condenser markets consist of units installed on commercial or industrial structures of generally less than 10 stories in height. Air-handling units, chillers and coils 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, the Company emphasizes the replacement market. Based on its 2004 level of sales of approximately $173 million, the Company estimates that it has a 13% share of the rooftop market and a 1% share of the coil market. Approximately 55% of the Company's sales now come from new construction and 45% from renovation/replacements. The percentage of sales for new construction vs. replacement to particular customers is related to the customer's stage of development. In the case of Wal-Mart, due to its growth posture, the Company's sales to this major customer were approximately 70% for new construction and 30% replacement. The Company purchases certain components, fabricates sheet metal and tubing and then assembles and tests its finished products. The Company's 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. The Company's other finished products are coils consisting of a sheet metal casing with tubing and fins contained therein, air-handling units consisting of coils, blowers and filters, condensing units consisting of coils, fans and compressors, which, with the addition of a refrigerant-to-water heat exchanger, become chillers, and make-up air units and heat recovery units. With regard to its standardized products, the Company currently has five groups of rooftop units: its RM and RN Series offered in 21 cooling sizes ranging from two to 70 tons; its RL Series, which is offered in 15 cooling sizes ranging from 40 to 230 tons; its HA Series, which is a horizontal discharge package for either rooftop or ground installation, offered in nine sizes ranging from four to 50 tons; and its HA/HB Series, which is offered in 11 sizes ranging from two to 50 tons. The Company manufactures a Model LL chiller, which is available in both air-cooled condensing and evaporative cooled configurations. The Company's air-handling units consist of the H/V Series and the Celebrity Series. The Company's heat recovery option applicable to its RM, RN and RL units, as well as its Celebrity air handlers, respond to the U.S. Clean Air Act mandate to increase fresh air in commercial structures. The Company's products are designed to compete on the higher quality end of standardized products. -1- The Company's customized products have extensive flexibility in sizes and configurations. Performance characteristics of its products range in cooling capacity from 28,000-4,320,000 BTU's and in heating capacity from 69,000-3,990,000 BTU's. All of the Company's products meet the Department of Energy's efficiency standards, which are published to 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. The Company has developed and is beginning to market a residential condensing unit (CB Series). Major Customers The Company's largest customer last year was Wal-Mart Stores, Inc. Sales to Wal-Mart were 14%, 18% and 14% of total sales, respectively, in 2004, 2003 and 2002. The Company has no written contract with this customer. The loss of Wal-Mart would have a material adverse affect on the Company. However, with the continuing expansion of the Company's customer base, management believes that the extent of its dependence on sales to this customer will diminish over a period of time. In order to diversify its customer base, the Company has added to and/or upgraded its sales representation in various markets. Sources and Availability of Raw Materials The most important materials purchased by the Company are steel, copper and aluminum, which are obtained from domestic suppliers. The Company also purchases from other domestic manufacturers certain components, including compressors, electric motors and electrical controls used in its products. The Company endeavors to obtain the lowest possible cost in its purchases of raw materials and components, consistent with meeting specified quality standards. The Company is not dependent upon any one source for its raw materials or the major components of its manufactured products. By having multiple suppliers, the Company believes that it will have adequate sources of supplies to meet its manufacturing requirements for the foreseeable future. The Company attempts to limit the impact of increases in raw materials and purchased component prices on its profit margins by negotiating with each of its major suppliers on a term basis from six months to one year. However, in 2004 cost increases in basic commodities, such as steel, copper and aluminum, were unprecedented in magnitude and severely impacted profit margins. In many instances, due to the significant price increases, suppliers refused to sell materials at the originally negotiated six-month or one year purchase order price. Distribution The Company employs a sales staff of 12 individuals and utilizes approximately 87 independent manufacturer representatives' organizations having 104 offices to market its products in the United States and Canada. The Company also has 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 the Company's 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. -2- The Company's products and sales strategy focus on "niche" markets. The targeted markets for its equipment are customers seeking products of better quality than offered, and/or options not offered, by standardized manufacturers. To support and service its customers and the ultimate consumer, the Company provides parts availability through two independent parts distributors and has factory service organizations at each of its plants. Also, a number of the manufacturer representatives utilized by the Company have their own service organizations, which, together with the Company, provide the necessary warranty work and/or normal service to customers. The Company's warranty on its products is: for parts only, the earlier of one year from the date of first use or 14 months from date of shipment; compressors (if applicable), an additional four years; on gas-fired heat exchangers (if applicable), 15 years; and on stainless steel heat exchangers (if applicable), 25 years. Research and Development All R&D activities of the Company are company-sponsored, rather than customer-sponsored. R&D has involved the HB, RM, RN and RL (rooftop units), LL (chillers), CB (condensing units) and WA (wall-hung units), as well as component evaluation and refinement, development of control systems and new product development. In the last three years, the Company has incurred an average of $917,000 per year in research and development expense. Backlog The Company had a current backlog as of March 1, 2005, of $33,184,000, compared to $37,384,000 at March 1, 2004. The current backlog consists of orders considered by management to be firm and substantially all of which will be filled by August 1, 2005; 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. The Company regularly reviews its working capital components with a view to maintaining the lowest level consistent with requirements of anticipated levels of operation. Its greatest needs arise during the months of July-November, the peak season for inventory (primarily purchased material) and accounts receivable. The Company's 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. The Company believes that it will have sufficient funds available to meet its working capital needs for the foreseeable future. Seasonality Sales of the Company's products are moderately seasonal with the peak period being July-November of each year. Competition In the standardized market, the Company competes primarily with Trane Company, a division of American Standard, Inc., Carrier Corporation, a subsidiary of United Technologies Corporation, Lennox International, Inc., and York International Corporation. All of these competitors are substantially larger and have greater resources than the Company. In the custom market, the Company competes with many larger and smaller manufacturers. The Company competes 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, the Company often is at a competitive disadvantage on sales of its products because of the emphasis placed on initial cost; whereas, in the replacement market and other owner-controlled purchases, the Company has a better chance of getting the business since quality and long-term cost are generally taken into account. -3- Employees As of March 1, 2005, the Company had 1,131 employees and 236 temporaries, none of whom is represented by unions. Management considers its relations with its employees to be satisfactory. Patents, Trademarks, Licenses and Concessions The Company does not consider any patents, trademarks, licenses or concessions held by it to be material to its business operations, other than patents issued regarding its heat recovery wheel option, blower, gas-fired heat exchanger, wall-hung curb and evaporative condenser desuperheater. Environmental Matters Laws concerning the environment that affect or could affect the Company's 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. The Company believes that it presently complies with these laws and that future compliance will not materially adversely affect the Company's earnings or competitive position.

Its 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 the Company's Internet website as soon as reasonably practical after the Company electronically files such material with, or furnishes it to, the SEC. Item 2. Properties. 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 NC 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. Production at this facility averaged approximately $14.4 million per month in 2004, which is 56% of the estimated capacity of the plant. Management deems this plant to be nearly ideal for the type of rooftop products being manufactured by the Company. The expansion facility is 39% (228,000 sq. ft.) utilized by the Company and 61% leased to a third party. The Company uses 22,000 sq. ft. for office space, 20,000 sq. ft. for warehouse space and 186,000 sq. ft. for manufacturing. The remaining 357,000 sq. ft. will afford the Company additional plant space for long-term growth. The Company's operations in Longview, Texas, are conducted in a plant/office building at 203-207 Gum Springs Road, containing 226,000 sq. ft. on 14 acres. The manufacturing area (approximately 219,000 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 13 acres were purchased in 2004 for future expansion. -4- The Company's 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. Item 3. Legal Proceedings. The Company is not a party to any pending legal proceeding which management believes is likely to result in a material liability and no such action is contemplated by or, to the best of its knowledge, has been threatened against the Company. Item 4. Submission of Matters to a Vote of Security Holders. No matter was submitted to a vote of security holders, through solicitation of proxies or otherwise, during the period from October 1, 2004, through December 31, 2004. -5- PART II Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities. The Company's Common Stock is traded on the NASDAQ National Market under the symbol "AAON".

Since its inception, no cash dividends have been paid on the Company's Common Stock and the Company does not anticipate paying cash dividends in the foreseeable future. There is a negative covenant under the Company's Revolving Credit and Term Loan Agreement which prohibits the declaration or payment of such dividends. Following repurchases of approximately 12% of its outstanding Common Stock between September 1999 and September 2001, the Company announced and began its current stock repurchase program on October 17, 2002, targeting repurchases of up to an additional 10% (1,325,000 shares) of its outstanding stock. Through December 31, 2004, the Company had repurchased a total of 1,078,064 shares under the current program for an aggregate price of $18,889,535, or an average of $17.52 per share.

Management's Discussion and Analysis of Financial Condition and Results of Operations. AAON engineers, manufactures and markets air-conditioning and heating equipment consisting of standardized and custom rooftop units, chillers, air-handling units, make-up units, heat recovery units, condensing units and coils. AAON sells its products to property owners and contractors through a network of manufacturers' representatives and its internal sales force. Demand for the Company's 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, the Company emphasizes 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 raw materials used in AAON's manufacturing processes are steel, copper and aluminum. The major component costs include compressors, electric motors and electronic controls. Selling, general, and administrative ("SG&A") costs include the Company's internal sales force, warranty costs, profit sharing and administrative expense. Warranty expense is estimated based on historical trends and other factors. The Company's warranty on its products is: for parts only, the earlier of one year from the date of first use or 14 months from date of shipment; compressors (if applicable), an additional four years, on gas-fired heat exchangers (if applicable), 15 years, and on stainless steel heat exchangers (if applicable), 25 years. On May 4, 2004, AAON Canada Inc., an Ontario corporation organized as a wholly-owned subsidiary of AAON, Inc., purchased certain assets of Air Wise Inc., of Mississauga, Ontario, Canada, which engineers, manufactures and sells custom air-handling units, make-up air units and packaged rooftop units for commercial and industrial buildings. The purchase price was $1,778,000, and was financed out of cash flow from operations. The Company's results of operations include the results of the acquisition from May 4, 2004 forward. On July 29, 2004, AAON Properties Inc., an Ontario corporation organized as a wholly-owned subsidiary of AAON, Inc., purchased property in Burlington, Ontario, Canada to relocate AAON Canada Inc. The facilities consist of an 82,000 square foot building (71,000 sq. ft. of manufacturing/warehouse space and 11,000 sq. ft. of office space) located at 279 Sumach Drive on a 5.6 acres tract of land. The office facilities of AAON, Inc. 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. The Company utilizes 39% of the expansion facility and the remaining 61% is leased to a third party. The operations of AAON Coil Products, Inc., are conducted in a plant/office building at 203-207 Gum Springs Road in Longview, Texas, containing 226,000 square feet (219,000 sq. ft. of manufacturing/warehouse and 7,000 sq. ft. of office space). In April 2004, AAON Coil Products purchased a 13-acre tract of land for future expansion. -8- Set forth below is income statement information with respect to the Company for years 2004, 2003 and 2002: Year Ended December 31, 2004 2003 2002 ---- ---- ---- (in thousands) Net sales $ 173,267 $ 148,845 $ 155,075 Cost of sales 145,807 112,596 117,193 --------------- --------------- --------------- Gross profit 27,460 36,249 37,882 --------------- --------------- --------------- Selling, general and administrative expenses 15,214 14,909 15,071 --------------- --------------- --------------- Income from operations 12,246 21,340 22,811 --------------- --------------- --------------- Interest expense (38) (21) (95) Interest Income 183 346 214 (12) 188 180 --------------- --------------- --------------- Income before income taxes 12,379 21,853 23,110 Income tax provision 4,858 7,626 8,499 --------------- --------------- --------------- Net income $ 7,521 $ 14,227 $ 14,611 =============== =============== =============== Results of Operations Net sales increased $24.4 million in 2004 compared to 2003, and decreased $6.2 million in 2003 compared to 2002. The increase in sales in 2004 was primarily attributable to the introduction of new products, the improving outlook for the U.S. economy, and the Air Wise acquisition, which has contributed $3,250,000 (1.9%) to sales since May 4, 2004. The increased sales were offset by computer and electrical outages that caused the closings of the Tulsa facility for four days, which also affected production at Longview and Canada. The decrease in sales for 2003 was primarily due to economic conditions in the United States, production issues with the manufacturing of new products and shipment delays by the Company's customers in the fourth quarter. Gross margins in 2004 were 15.8% compared to 24.4% in 2003. Gross profit decreased $8.8 million (24.2%) to $27.5 million in 2004 from $36.2 million in 2003 and decreased $1.6 million (4.3%) to $36.2 million from $37.9 million in 2003 compared to 2002. The decrease in margins for 2004 compared to 2003 and 2002 was due to price increases in steel, copper and aluminum, startup costs associated with a new coil project, closings of the Tulsa facility for four days due to computer and electrical outages, which also affected the Longview and Canada facilities, and equipment failures at the Company's Longview, Texas, facility that prevented coil production needed by the Tulsa facility. The Company instituted a product price increase to its customers in April 2004, in an attempt to offset the increases in steel, copper and aluminum. Due to the Company's high backlog, orders with old pricing had to flow through the system before new orders began to reflect the new pricing. In addition, the Company initiated another product price increase to its customers in December 2004, because the April price increase did not keep pace with interim material price increases. The Company attempts to limit the impact of price increases on these materials by entering into cancelable fixed price contracts with its major suppliers for periods of 6-12 months. In many instances, due to significant price increases in 2004, suppliers refused to sell materials at the originally negotiated six-month or one year purchase order price. While gross margins decreased as a result of lower sales in 2003, the margin percentage remained consistent with those of previous years. -9- Steel, copper and aluminum are high volume materials used in the manufacturing of the Company's products, which are obtained from domestic suppliers. The Company also purchases from other domestic manufacturers certain components, including compressors, electric motors and electrical controls used in its products. The suppliers of these components are significantly affected by the rising raw material costs, as steel, copper and aluminum are used in the manufacturing of their products. The Company is also experiencing price increases from component part suppliers. Selling, general and administrative expenses increased $300,000 (2.0%) in 2004 compared to 2003 due primarily to increases in bad debt expense. The SG&A decrease of $200,000 (1.1%) in 2003 compared to 2002 was attributable primarily to improved product quality, offset by advertising, state taxes and employee compensation cost increases. Interest expense was $38,000, $21,000 and $95,000 in 2004, 2003 and 2002, respectively. The reduction in interest expense was due to the retirement of all long-term debt in 2002, lower average borrowings under the revolving credit facility in 2004 and 2003 compared to 2002, and lower average interest rates. Interest income was $183,000, $350,000 and $210,000 in 2004, 2003, and 2002 respectively, due to investments in short-term money markets and certificates of deposit. Other expense was $12,000 in 2004 and other income was $200,000 in 2003 and 2002. Other income is attributable primarily to rental income from the Company's expansion facility. Financial Condition and Liquidity Net accounts receivable increased $4.6 million at December 31, 2004, compared to December 31, 2003, due to an increase in sales and the Air Wise acquisition. Inventories increased $1.2 million at December 31, 2004, compared to December 31, 2003, due to procurement of inventory to accommodate increased sales and increased inventory values related to higher raw material and component parts costs. With the backlog at $33.2 million, the bulk of the increase in inventories is committed for future manufacturing. Prepaid expenses decreased by $2.2 million at December 31, 2004, compared to December 31, 2003, due to deposits on equipment commitments being placed in service in 2004. Accounts payable and accrued liabilities increased $4.0 million at December 31, 2004, compared to December 31, 2003, due to timing of payments to vendors and commissions payable. The Company generated $16.2 million, $16.5 million and $21.9 million cash from operating activities in 2004, 2003 and 2002, respectively. Operating cash flows in 2004 consisted of $7.5 million of net income, $3.0 million of working capital and other changes. The decrease in cash provided from operating activities in 2004 is primarily due to an increase in cost of sales and an increase in accounts receivable. Operating cash flows in 2003 consisted of $14.2 million of net income, $(3.2) million in working capital and other changes. The decrease in 2003 is primarily due to an increase in inventories. Operating cash flows in 2002 consisted of $14.6 million of net income, $2.4 million in working capital and other changes. Cash flows used in investing activities were $11.7 million, $7.6 million and $16.1 million in 2004, 2003 and 2002, respectively. Cash flows used in investing activities in 2004 related to capital expenditure additions totaling $17 million, reflecting primarily additions to machinery and equipment, a sheet metal facility at the Tulsa plant and renovations made to the Company's Tulsa manufacturing and Longview office facilities. In 2003 and 2002 cash used in investing activities was comprised primarily of capital expenditures totaling $7.7 million and $6.1 million, respectively. All capital expenditures and building renovations were financed out of cash generated from operations. In 2002, the Company invested $10 million in a certificate of deposit that matured in 2004 and an additional $3 million was invested in certificate of deposits in 2004, which matures in the first quarter of 2005. Due to anticipated production demands, the Company expects to expend approximately $8 million in 2005 for equipment requirements. The Company expects the cash requirements to be provided from cash flow from operations. -10- Cash flows used in financing activities were $9.9 million, $7.7 million and $1.9 million in 2004, 2003 and 2002, respectively. In October 2002, the Company's Board of Directors authorized a stock buyback program to repurchase up to 1,325,000 shares of stock. There were 265,100 shares of stock repurchased for a total of $5.0 million and 597,001 shares of stock repurchased for a total of $9.9 million in 2004 and 2003, respectively, with 215,963 shares of stock repurchased for a total of $4.0 million in 2002. Additionally, during 2004, 2003 and 2002, the Company had net borrowings/(repayments) of $(5.4) million, $1.8 million and $3.1 million, respectively, under its revolving credit facility and repaid $1.9 million of long-term debt in 2002. The Company's revolving credit facility (which currently extends to July 30, 2005) provides for maximum borrowings of $15.2 million. Interest on borrowings is payable monthly at the Wall Street Journal prime rate less .5% or LIBOR plus 1.6%, at the election of the Company. The Company had no borrowings under the revolving credit facility as of December 31, 2004. Borrowings available under the revolving credit facility at December 31, 2004 were $14.6 million. In addition, the Company has a $600,000 Letter of Credit that expires December 31, 2005. The credit facility requires that the Company maintain a certain financial ratio and prohibits the declaration of dividends. Management believes the Company's bank revolving credit facility (or comparable financing), and projected cash flows from operations will provide the necessary liquidity and capital resources to the Company for the foreseeable future. The Company's belief that it will have the necessary liquidity and capital resources is based upon its knowledge of the HVAC industry and its place in that industry, its ability to limit the growth of its business if necessary, and its relationship with its existing bank lender. For information concerning the Company's revolving credit facility at December 31, 2004, see Note 4 to the financial statements included in this report. Commitments and Contractual Agreements The Company is a party to several short-term, cancelable, fixed price contracts with major suppliers for the purchase of raw material and component parts. The Company has cancelable commitments to purchase machinery and equipment at a cost of $1.9 million. 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 the Company's results of operations, financial position and cash flows. The Company reevaluates its estimates and assumptions on a monthly basis. The following accounting policies may involve a higher degree of estimation or assumption: Allowance for Doubtful Accounts - The Company establishes 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. -11- Inventory Reserves - The Company establishes 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: for parts only, the earlier of one year from the date of first use or 14 months from date of shipment; compressors (if applicable), an additional four years; on gas-fired heat exchangers (if applicable), 15 years; and on stainless steel heat exchangers (if applicable), 25 years. Warranty expense is estimated based on the Company's warranty period, historical warranty trends and associated costs, and any known identifiable warranty issue. Due to the absence of warranty history on new products, an additional provision may be made for such products. Historically, reserves have been within management's expectations. Stock Compensation - The Company has elected to follow Accounting Principles Board Opinion No. 25 ("APB 25"), Accounting for Stock Issued to Employees and related interpretations in accounting for stock options. Under "fixed plan" accounting in APB 25, because the exercise price of the Company's options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. The Company has adopted pro forma disclosures of SFAS 123. New Accounting Pronouncements FASB Statement 123 (R) replaces FASB Statement No.123, Accounting for Stock-Based Compensation, and supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees. The Statement requires measurement of the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The compensation cost will be 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. The Statement applies to all awards granted and any unvested awards at June 15, 2005. SFAS 123 (R) will be effective for interim reporting beginning after June 15, 2005. The Company has not determined the impact of the adoption of SFAS 123 (R). Forward-Looking 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. The Company undertakes 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. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. The Company is subject to interest rate risk on its revolving credit facility which bears variable interest based upon a prime or LIBOR rate. The Company had no outstanding balance as of December 31, 2004. -12- Foreign sales accounted for only 2% of the Company's sales in 2004 and the Company accepts payment for such sales in U.S. and Canadian dollars; therefore, the Company believes it is not exposed to significant foreign currency exchange rate risk on these sales. Foreign currency transactions and financial statements are translated in accordance with Statement of Financial Standards No. 52, Foreign Currency Translation. The Company uses the U.S. dollar as its functional currency, except for the Company's 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 are denominated in Canadian currency and are included in the results of operations as incurred. Important raw materials purchased by the Company are steel, copper and aluminum, which are subject to price fluctuations. The Company attempts to limit the impact of price increases on these materials by entering cancelable fixed price contracts with its major suppliers for periods of 6 -12 months. However, in 2004 cost increases in basic commodities, such as steel, copper and aluminum, were unprecedented in magnitude and severely impacted profit margins. In many instances, due to significant price increases, this year, suppliers refused to sell materials at the originally negotiated six-month or one year purchase order price. The Company does not utilize derivative financial instruments to hedge its interest rate or raw materials price risks. Item 8. Financial Statements and Supplementary Data. The financial statements and supplementary data are included commencing at page 27. Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. The information called for by Item 304 of Regulation S-K has been previously reported in the Company's Form 8-K dated June 25, 2004. Item 9A. Controls and Procedures. (a) Evaluation of Disclosure Controls and Procedures AAON's Chief Executive Officer and Chief Financial Officer have evaluated the Company's disclosure controls and procedures and concluded that these controls and procedures were ineffective as of December 31, 2004, because of the material weaknesses discussed below. (b) Management's Annual Report on Internal Control over Financial Reporting The management of AAON, Inc. and its subsidiaries (AAON), is responsible for establishing and maintaining adequate internal control over financial reporting. AAON's internal control system was designed to provide reasonable assurance to the Company's 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 conducting our evaluation of the effectiveness of our internal control over financial reporting, we have excluded due to its size and complexity the acquisition of AAON Canada Inc., which was completed in May, 2004. This acquisition created a second geographic location distinct from that of our United States operations in which financial reporting will continue to occur with their own control environment, control activities and proprietary information technology systems. Collectively, this acquisition constituted 1.7% of total assets as of December 31, 2004, 1.9% of total revenues and (11)% of net earnings for the year then ended (See Note 1 to the consolidated financial statements which contains further discussion of this acquisition and its impact on our consolidated financial statements). We plan to fully integrate our reporting locations into a common reporting framework in 2005. -13- An internal control material weakness is a significant deficiency, or aggregation of deficiencies, that results in a more than remote likelihood that a material misstatement in annual or interim financial statements will not be prevented or detected on a timely basis by employees in the normal course of their work. An internal control significant deficiency, or aggregation of deficiencies, is a deficiency that results in a more than remote likelihood that a misstatement in annual or interim financial statements is more than inconsequential. The management of AAON assessed the effectiveness of the Company's internal control over financial reporting, as defined in Securities Exchange Commission Act Rule 13a-15(f) as of December 31, 2004, and this assessment considered the following material weaknesses in the company's internal control over financial reporting, specifically relating to inventory accounting: 1) At December 31, 2004, material weaknesses existed in information technology general controls that impaired the reliability of AAON's manufacturing and inventory application processing functions and automated controls. These weaknesses, in turn, undermined the reliability of user controls over manufacturing and inventory processing, which were dependent upon the integrity of computer-generated reports. The specific factors giving rise to this material weakness include a) deficiencies in the authorization, development, testing, and movement of changes to AAON's inventory and manufacturing applications and b) significant functional complexity of the inventory and manufacturing applications that create user dependence upon application-based controls to prevent or detect errors, omissions and irregularities in processing. 2) At December 31, 2004, a material weakness existed with respect to the preparation of certain adjustments recorded by management related to the valuation of inventory. Our external auditors discovered during the completion of the audit of the 2004 financial statements that adjustments recorded by management inaccurately valued inventory and proposed certain audit adjustments to correct the misstatement. The proposed audit adjustments were determined to be material and, by reason of that fact, a material weakness would be deemed to exist. These adjustments were recorded in the financial statements of AAON. The proposed audit adjustments related to a) the capitalization of certain purchase price variances and b) absorption of manufacturing overhead. Because of the aforementioned material weaknesses, management determined the Company's internal control over financial reporting to be ineffective at December 31, 2004. We intend to implement changes to our internal controls in the future to address these material weaknesses. We will consider implementation of the following, as well as other additional procedures: o Develop controls over production program changes that will assure that all, and only, authorized changes to production programs have been properly designed, tested and moved into production. o Develop controls to assure non-routine adjustments to inventory are appropriately tested before they are recorded in the financial statements. o Develop controls to assure manufacturing overhead related to inventory is appropriately considered in our financial reporting. In making its 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. Because of the material weakness described in the preceding paragraph, management believes that, as of December 31, 2004, the Company's internal control over financial reporting was not effective based on those criteria. -14- AAON's independent registered public accounting firm has issued an attestation report on management's assessment of the Company's internal control over financial reporting. Date: March 8, 2005 /s/ Norman H. Asbjornson -------------------------------- Norman H. Asbjornson Chief Executive Officer /s/ Kathy I. Sheffield -------------------------------- Kathy I. Sheffield Chief Financial Officer (c) Attestation Report of the Registered Public Accounting Firm AAON, Inc. stockholders We have audited management's assessment, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting (Management's Assessment), that AAON, Inc. (a Nevada Corporation) and subsidiaries (collectively, AAON) did not maintain effective internal control over financial reporting as of December 31, 2004, because of the effect of material weaknesses identified in management's assessment, based on criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). AAON'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. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of 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, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions. As indicated in Management's Annual Report on Internal Control over Financial Reporting, management has excluded the May 4, 2004 acquisition of Airwise, Inc. from management's evaluation of the effectiveness of internal control over financial reporting. Accordingly, we did not perform procedures to evaluate the design and operating effectiveness of internal controls related to the acquired business. 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. -15- 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. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weaknesses relating to inventory accounting have been identified and included in management's assessment. 1) At December 31, 2004, material weaknesses existed in information technology general controls that impaired the reliability of AAON's manufacturing and inventory application processing functions and automated controls. These weaknesses, in turn, undermined the reliability of user controls over manufacturing and inventory processing, which were dependent upon the integrity of computer-generated reports. The specific factors giving rise to this material weakness include a) deficiencies in the authorization, development, testing, and movement of changes to AAON's inventory and manufacturing applications and b) significant functional complexity of the inventory and manufacturing applications that create user dependence upon application-based controls to prevent or detect errors, omissions, and irregularities in processing. 2) At December 31, 2004, we discovered a material weakness existed with respect to the preparation of certain adjustments recorded by management related to the valuation of inventory. Our external auditors discovered during the completion of the audit of the 2004 financial statements that the adjustments recorded by management inaccurately valued inventory and proposed certain audit adjustments to correct the misstatement. The proposed audit adjustments were determined to be material and were subsequently recorded in the financial statements of AAON. The proposed audit adjustments related to a) the capitalization of certain purchase price variances and b) absorption of manufacturing overhead. These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2004 financial statements, and this report does not affect our report dated March 8, 2005 on those financial statements. In our opinion, management's assessment that AAON did not maintain effective internal control over financial reporting as of December 31, 2004, is fairly stated, in all material respects, based on criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also in our opinion, because of the effects of the material weaknesses described above on the achievement of the objectives of the control criteria, AAON has not maintained effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control--Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). We do not express an opinion or any other form of assurance on management's statement referring to intended changes to the Company's system of internal controls over financial reporting and integration of financial reporting locations and framework. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2004 and related consolidated statements of income, stockholders' equity, and cash flows for the year then ended of AAON, Inc. and subsidiaries and our report dated March 8, 2005 expressed an unqualified opinion. /s/ GRANT THORNTON LLP Tulsa, Oklahoma March 8, 2005 -16- (d) Changes in Internal Control over Financial Reporting There have been no significant changes in internal control over financial reporting that occurred during the fourth quarter of 2004 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

(the Company, a Nevada corporation) is engaged in the manufacture and sale of commercial rooftop air conditioners, heating equipment and air conditioning coils through its wholly-owned subsidiaries AAON, Inc. (AAON, an Oklahoma corporation) AAON Coil Products, Inc. (ACP, a Texas corporation) and AAON Canada, Inc., d/b/a Air Wise (AAON Canada, an Ontario corporation). AAON Properties Inc., (an Ontario corporation) is the lessor of property in Burlington, Ontario, Canada, to AAON Canada. The consolidated financial statements include the accounts of the Company and its subsidiaries, AAON, ACP, AAON Canada and AAON Properties Inc. All significant intercompany accounts and transactions have been eliminated. Currency Foreign currency transactions and financial statements are translated in accordance with Statement of Financial Standards No. 52, Foreign Currency Translations. The Company uses the U.S. dollar as its functional currency, except for the Company's 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 are denominated in Canadian currency and 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 in the consolidated financial statements and accompanying notes. The following accounting policies may involve a higher degree of estimation or assumption: Allowance for Doubtful Accounts - The Company establishes 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. Inventory Reserves - The Company establishes 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: for parts only, the earlier of one year from the date of first use or 14 months from date of shipment; compressors (if applicable), an additional four years; on gas-fired heat exchangers (if applicable), 15 years; and on stainless steel heat exchangers (if applicable), 25 years. Warranty expense is estimated based on the Company's warranty period, historical warranty trends and associated costs, and any known identifiable warranty issue. Due to the absence of warranty history on new products, an additional provision may be made for such products. Actual results could differ from those estimates. -31- 1. Business, Summary of Significant Accounting Policies and Other Financial Data (continued) Revenue Recognition The Company recognizes revenues from sales of products at the time of shipment.

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 as of December 31, 2004 or 2003. -35- 1.

The compensation cost will be 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. The Statement applies to all awards granted and any unvested awards at June 15, 2005. SFAS 123 (R) will be effective for interim reporting beginning after June 15, 2005. The Company has not determined the impact of the adoption of SFAS 123 (R).

Benefit Plans (continued) For purposes of the stock compensation information presented in Note 1, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions: 2004 2003 2002 --------------------------------------- Expected dividend yield 0% 0% * Expected volatility 36.70% 37.80% * Risk-free interest rate 4.24% 3.73% * Expected life 8 yrs 8 yrs * *The Company granted no options in 2002. The Company sponsors a defined contribution benefit plan. Employees may make contributions at a minimum of 1% and a maximum of 15% of compensation. The Company may, on a discretionary basis, contribute a Company matching contribution not to exceed 6% of compensation. The Company made matching contributions of $546,000, $585,000 and $535,000 in 2004, 2003 and 2002, respectively. The Company maintains 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. Profit sharing expense was $1,408,000, $2,428,000 and $2,573,000 for the years ended December 31, 2004, 2003 and 2002, respectively. 8. 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 the Company's 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 the Company's common stock. The rights become exercisable after a person has acquired, or a tender offer is made for, 15% or more of the common stock of the Company. 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 the Company's common stock having a market value equal to two times the exercise price. The rights may be redeemed by the Company for $0.001 per right until a person or group has acquired 15% of the Company's common stock. The rights expire on August 20, 2012. -42- 9. Contingencies The Company is subject to claims and legal actions that arise in the ordinary course of business. Management believes that the ultimate liability, if any, will not have a material effect on the Company's results of operations or financial position. 10.
