("AFS"), a wholly owned subsidiary of the Company. Since December 31, 2002, AFS has sold to other financing companies, or collected from customers, payment on substantially all contracts. AFS has sufficient reserves for potentially uncollectible amounts on remaining contracts.

On June 30, 2004, the Company sold substantially all of the assets and liabilities of Superior Industries of Morris, Inc. (Superior) to Superior Industries, LLC. Superior was part of the Company's Aggregate and Mining Group.

The Company's strategy is to be the industry's most cost-efficient producer in each of its product lines, while continuing to develop innovative new products and provide first class service for its customers. Management believes that the Company is the technological innovator in the markets in which it operates and is well positioned to capitalize on the need to rebuild and enhance roadway infrastructure, both in the United States and abroad.

The Company's business units have separate management teams and offer different products and services. The business units have been aggregated into four reportable business segments based upon the nature of the product or services produced, the type of customer for the products and the nature of the production process. The reportable business segments are (i) Asphalt Group, (ii) Aggregate and Mining Group, (iii) Mobile Asphalt Paving Group and (iv) Underground Group. All remaining companies as well as corporate expenses and federal tax expenses for all business segments are included in the "Other Business Units" category for reporting.

Financial information in connection with the Company's financial reporting for segments of a business under Statement of Financial Accounting Standards(SFAS) No. 131 is included in Note 16 to "Notes to Consolidated Financial Statements - Operations by Industry Segment and Geographic Area," appearing in Appendix A of this report.

The Asphalt Group segment is made up of three business units: Astec, Inc. ("Astec"), Heatec, Inc. ("Heatec") and CEI Enterprises, Inc. ("CEI"). These business units design, manufacture and market a complete line of asphalt plants and related components, heating and heat transfer processing equipment and storage tanks for the asphalt paving and other non-related industries.

Astec designs, engineers, manufactures and markets a complete line of portable, stationary and relocatable hot-mix asphalt plants and related components under the ASTEC® trademark. An asphalt mixing plant typically consists of heating and storage equipment for liquid asphalt (manufactured by CEI or Heatec); cold feed bins for storing aggregates; a drum mixer (batch or Double Barrel type unit) for drying, heating and mixing; a baghouse composed of air filters and other pollution control devices; hot storage bins or silos for temporary storage of hot-mix asphalt; and a control house. Astec introduced the concept of high plant portability in 1979. Its current generation of portable asphalt plants is marketed as the Six Pack^TM and consists of six or more portable components, which can be disassembled, moved to the construction site and reassembled, thereby reducing relocation expenses. High plant portability represents an industry innovation developed and successfully market ed by Astec. Astec's enhanced version of the Six Pack^TM, known as the Turbo Six Pack^TM, is a highly portable plant which is especially useful in less populated areas where plants must be moved from job-to-job and can be disassembled and erected without the use of cranes.

The components in Astec's asphalt mixing plants are fully automated and use both microprocessor-based and programmable logic control systems for efficient operation. The plants are manufactured to meet or exceed federal and state clean air standards. Astec has also developed specialized asphalt recycling equipment for use with its hot-mix asphalt plants.

Heatec designs, engineers, manufactures and markets a variety of thermal fluid heaters, process heaters, waste heat recovery equipment, liquid storage systems and polymer and rubber blending systems under the HEATEC® trademark. Heatec manufactures a complete line of asphalt heating and storage equipment to serve the hot-mix asphalt industry. In addition, Heatec builds a wide variety of industrial heaters to fit a broad range of applications, including heating equipment for marine vessels, roofing material plants, refineries, chemical processing, rubber plants and agribusiness. Heatec has the technical staff to custom design heating systems and has systems operating as large as 50,000,000 BTU's per hour.

CEI designs, engineers, manufactures and markets heating equipment and storage tanks for the asphalt paving industry and rubber and polymer blending systems. CEI's heating equipment uses hot oil, direct fired or electric heating processes. CEI's equipment includes portable and stationary tank models with capacities up to 35,000 gallons each. In addition, CEI manufactures low cost asphalt plants for international and domestic markets.

Astec markets its hot-mix asphalt products both domestically and internationally. The principal purchasers of asphalt and related equipment are highway contractors. Asphalt equipment is sold directly to the customers through Astec's domestic and international sales departments, although independent agents are also used to market asphalt plants and their components in international markets.

Heatec equipment is marketed through both direct sales and dealer sales. Manufacturers' representatives sell heating products for applications in industries other than the asphalt industry. CEI equipment is marketed domestically and internationally through direct sales and through independent agents.

In total, the products of the Asphalt Group segment are marketed by approximately 34 direct sales employees, 20 domestic independent distributors and 30 international independent distributors.

Raw materials used in the manufacture of products include carbon steel and various types of alloy steel, which are normally purchased from distributors. Raw materials for manufacturing are normally readily available. Most steel is delivered on a "just-in-time" arrangement from the supplier to reduce inventory requirements at the manufacturing facilities.

This industry segment faces strong competition in price, service and product performance and competes with both large publicly-held companies with resources significantly greater than those of the Company and with various smaller manufacturers. Domestic hot-mix asphalt plant competitors include Gencor Industries, Inc. and Terex Roadbuilding. In the international market, the hot-mix asphalt plant competitors include Ammann, Marini and Ermont. The market for the Company's heat transfer equipment is diverse because of the multiple applications for such equipment. Competitors for the construction product line of heating equipment include, among others, Gencor/Hyway Heat Systems, American Heating, Burke Heating Systems and Pearson Heating Systems, Inc. Competitors for the industrial product line of heating equipment include GTS Energy Systems, Fulton Thermal Corporation, Vapor Power International, NATCO, Broach and TFS, among others.

At December 31, 2004, the Asphalt Group segment employed 781 individuals, of which 590 were engaged in manufacturing, 69 in engineering and 122 in selling, general and administrative functions.

The backlog for the hot-mix asphalt and heat transfer equipment at December 31, 2004 and 2003 was approximately $35,647,000 and $24,889,000, respectively.

The Company's Aggregate and Mining Group is comprised of six business units focused on the aggregate, metallic mining and recycling markets. These business units achieve their strength by distributing products into niche markets and drawing on the advantages of brand recognition in the global market. These business units are Telsmith, Inc. ("Telsmith"), Kolberg-Pioneer, Inc. ("KPI"), Astec Mobile Screens, Inc. ("AMS"), Johnson Crushers International, Inc. ("JCI"), Breaker Technology Ltd./Breaker Technology Inc. ("BTI") and Osborn Engineered Products, SA (Pty) Ltd ("Osborn"). Previously, this group also included Superior Industries of Morris, Inc. (Superior). As discussed earlier, the Company sold substantially all of the assets and liabilities of Superior on June 30, 2004.

Founded in 1906, Telsmith is the oldest subsidiary of the group, with almost 100 years of experience applying new technology to advance the stone reduction and sizing process. Today, TELSMITH® is a design, manufacture, sales and customer support organization focused on serving the aggregate and metallic mining industries. Telsmith's core products are cone (Gyrasphere®), jaw and impact crushers, which are recognized for their reliability and performance. Complementing the crusher lines are a wide range of heavy-duty feeders and scalping screens, as well as finishing screens specifically suited for sizing stone to meet stringent aggregate specifications.

Recent additions to the Telsmith crushing lines are the "SBS" cone crushers and Iron Giant® jaw crushers. These innovative crushers incorporate the latest technology available to enhance productivity, reliability, and safety. Specifically incorporated into these machines are features that enhance a processing plant's ability to automate the production process.

Telsmith has extended the core product offering to include complete production systems. A variety of portable plant arrangements, relocatable modular systems, and a low-installed-cost solution for production plants are available.

Telsmith is an ISO 9001:2000 certified company that is dedicated to providing superior field support and expertise for its customers.

KPI designs, manufactures and supports a complete line of aggregate processing equipment for the sand and gravel, mining, quarrying and concrete recycling markets under the well-known Pioneer® and Kolberg® product brand names. This equipment, along with the full line of portable and stationary aggregate and ore processing products from JCI, are jointly marketed through an extensive network of KPI/JCI dealers.

Pioneer® products include a complete line of primary, secondary, tertiary and quaternary crushers, including jaws, cones, horizontal shaft impact, vertical shaft impact and roll crushers. KPI rock crushers are used by mining, quarrying and sand and gravel producers to crush oversized aggregate to salable size, in addition to their use for recycled concrete and asphalt. Equipment furnished by Pioneer can be purchased as individual components, as portable plants for flexibility or as completely engineered systems for both portable and stationary applications. Included in the portable area is a highly-portable Fast Pack® System, featuring quick setup and teardown, thereby maximizing production time and minimizing down time. Also included in the portable Pioneer® line are the fully self-contained and self-propelled Fast Trax® Track-Mounted-Jaw and HSI Crushers in four different models, which are ideal for either recycle or hard rock applications, allowing the prod ucer to move the equipment to the material.

Kolberg® sand classifying and washing equipment is relied upon to clean, separate and re-blend deposits to meet the size specifications for critical applications. The Kolberg® product line includes fine and coarse material washers, log washers, blade mills and sand classifying tanks. Screening plants are available in both stationary and highly portable models, and are complemented by a full line of radial stacking and overland belt conveyors.

Kolberg® conveying equipment, including telescopic conveyers, is designed to move or store aggregate and other bulk materials, typically in radial cone-shaped stockpiles. The Wizard Touch™ automated controls are designed to add efficiency and accuracy to whatever the stockpile specifications require.

AMS, formerly Production Engineered Products, Inc., located in Sterling, Illinois, develops, manufactures and markets mobile screening plants, portable and stationary screen structures, vibrating screens designed for the recycle, crushed stone, sand and gravel, industrial and general construction industries. These screening plants include the AMS Vari-Vibe and Duo-Vibe high frequency screens. The AMS high frequency screens are used for chip sizing, sand removal and sizing recycled asphalt where conventional screens are not ideally suited.

During 2004, AMS broadened its product line with track-mounted high frequency and conventional screening plants in multiple sizes for the aggregate, recycle, and recycle asphalt processing markets.

Portable plants combine various configurations of cone crushers, horizontal screens, Combo™ screens, and conveyors mounted on tow-away chassis. Because transportation costs are high, producers use portable equipment to operate nearer to their job sites. Portable plants allow the aggregate producers to quickly and efficiently move their equipment from one location to another. JCI and KPI jointly market a portable rock crushing plant appropriately named the Fast Pack®. This complete, but portable plant, with production capability in excess of 500 tons per hour when relocated, can be reassembled and ready for production in under four hours, making it one of the industry's most mobile and cost-effective high-capacity crushing systems. The Fast Pack® design reduces operating costs by as much as 30%, compared to traditional plant designs, and the user-friendly controls provide a safer work environment for the user.

JCI recently introduced a series of track-mounted crusher products known as Fast Trax™ . These units are self contained and easily relocated. The models FT 5162 and FT 6203 were launched in 2004.

BTI designs, manufactures and markets hydraulic rock breaker systems for the aggregate, mining and recycling industries. They also design and manufacture a complete line of four-wheel drive articulated utility vehicles for underground mines and quarries. Complementing their DS Series of scaling vehicles as well as a new scaling vehicle under development, BTI's product line now includes a highly effective and innovative vibratory pick scaling attachment.

In addition to the quarry and mining industries, BTI designs, manufactures and markets a complete line of hydraulic breakers, compactors and demolition attachments for the North American construction and demolition markets. These attachments are designed to suit a variety of equipment including excavators, backhoe loaders, wheel loaders, and skid steer loaders.

BTI offers an extensive aftermarket sales and service program through a highly qualified and trained dealer network.

This equipment is used in the aggregate, mineral mining, metallic mining and recycling industries. Osborn has been a licensee of Telsmith's technology for over 50 years. In addition to Telsmith, Osborn also manufactures under license to American Pulverizer (USA), IFE (Austria) and Mogensen (UK) and has an in-house brand, Hadfields. Osborn also offers the following equipment: double-toggle jaw crushers; rotary breakers; roll crushers; rolling ring crushers; mills; out-of-balance or exciter-driven screens and feeders; portable, track-mounted or fixed crushing and screening plants; conveyor systems; and a full range of idlers.

Aggregate processing and mining equipment is marketed by approximately 74 direct sales employees, 277 independent domestic distributors and 207 independent international distributors. The principal purchasers of aggregate processing equipment include highway and heavy equipment contractors, open mine operators, quarry operators and foreign and domestic governmental agencies.

Raw materials used in the manufacture of products include carbon steel and various types of alloy steel, which are normally purchased from distributors. BTI purchases hydraulic breakers under a long-term purchasing contract from a Japanese supplier and also purchases demolition attachments from an Italian supplier. Both the Japanese and Italian suppliers have sufficient capacity to meet BTI's anticipated demand and have been reliable sources for 20 and 10 years, respectively; however, alternative suppliers exist for both of these components should any supply disruptions occur.

The Aggregate and Mining Group faces strong competition in price, service and product performance. Aggregate processing and mining equipment competitors include Metso (Nordberg); Sandvik (formerly Svedala Industri AB); Cedarapids, Powerscreen and Finley, subsidiaries of Terex Corporation; Extec; Pegson; Deister; Continental; Eagle Iron Works; Thor; and other smaller manufacturers, both domestic and international.

At December 31, 2004, the Aggregate and Mining Group segment employed 1,125 individuals, of which 797 were engaged in manufacturing, 99 in engineering and engineering support functions, and 229 in selling, general and administrative functions.

Telsmith has a labor agreement covering approximately 128 manufacturing employees, which expires on September 14, 2007. None of Telsmith's other employees are covered by a collective bargaining agreement.

Approximately 74 of Osborn's manufacturing employees are members of three national labor unions with agreements that expire on June 30, 2005.

At December 31, 2004 and 2003, the backlog for the Aggregate and Mining Group was approximately $47,311,000 and $39,508,000, respectively.

The Mobile Asphalt Paving Group is comprised of Roadtec, Inc. ("Roadtec") and Carlson Paving Products, Inc. ("Carlson"). Roadtec designs, engineers, manufactures and markets asphalt pavers, material transfer vehicles and milling machines. Carlson designs and manufactures asphalt paver screeds that attach to the asphalt paver to control the width and depth of the asphalt as it is applied to the roadbed. Carlson also manufactures Windrow pickup machines which transfer hot mix asphalt from the road bed into the paver's hopper.

Roadtec's patented Shuttle Buggy® is a mobile, self-propelled material transfer vehicle which allows continuous paving by separating truck unloading from the paving process while remixing the asphalt. A typical asphalt paver must stop paving to permit truck unloading of asphalt mix. By permitting continuous paving, the Shuttle Buggy® allows the asphalt paver to produce a smoother road surface, as well as reduce the time required to pave the road surface. As a result of the pavement smoothness achieved with this machine, certain states are now requiring the use of the Shuttle Buggy®. Studies using infrared technology have revealed problems caused by differential cooling of the hot-mix during hauling. The Shuttle Buggy® remixes the material to a uniform temperature and gradation, thus eliminating these problems.

Asphalt pavers are used in the application of hot-mix asphalt to the road surface. Roadtec pavers have been designed to minimize maintenance costs while exceeding road surface smoothness requirements. Roadtec also manufactures a paver model designed for use with the material transfer vehicle described above, which, when used together, reduce machine operating and maintenance costs.

Roadtec manufactures milling machines designed to remove old asphalt from the road surface before new asphalt mix is applied. Roadtec's milling machine lines, for larger jobs, are manufactured with a simplified control system, wide conveyors, direct drives and a wide range of horsepower and cutting capabilities to provide versatility in product application. Additional upgrades and options are available from Roadtec to enhance its products and their capabilities.

Carlson's patented screeds are part of the asphalt paving machine that lays asphalt on the roadbed at a desired thickness and width, while smoothing and compacting the surface. Carlson screeds can be configured to fit many types of asphalt paving machines. A Carlson screed uses a hydraulic powered generator to electrify elements that heat a screed plate so that asphalt will not stick to it while paving. The generator is also available to power tools or lights for night paving. Carlson offers options which allow extended paving widths and the addition of a curb on the road edge.

The Mobile Asphalt Paving Group equipment is marketed both domestically and internationally to highway and heavy equipment contractors, utility contractors and foreign and domestic governmental agencies. Mobile construction equipment is marketed both directly and through dealers. This segment employs 26 direct sales staff, 31 domestic independent distributor and 45 foreign independent distributors.

Raw materials used in the manufacture of products include carbon steel and various types of alloy steel, which are normally purchased from steel distributors and other sources. Raw materials for manufacturing are normally readily available. Most steel is delivered on a "just-in-time" arrangement from the supplier to reduce inventory requirements at the manufacturing facilities. Components used in the manufacturing process include engines, gearboxes, power transmissions and electronics systems.

The Mobile Asphalt Paving Group segment faces strong competition in price, service and performance. Paving equipment and screed competitors include Caterpillar Paving Products, Inc., a subsidiary of Caterpillar, Inc.; Blaw-Knox Construction Equipment Company, a subsidiary of Ingersoll-Rand Company; CMI Corporation, a subsidiary of Terex Corporation; Vogele, a subsidiary of Wirtgen, and Dynapac. The segment's milling machine equipment competitors include Wirtgen America, Inc.; CMI Corporation, a subsidiary of Terex Corporation; and Caterpillar, Inc.

At December 31, 2004, the Mobile Asphalt Paving Group segment employed 393 individuals, of which 269 were engaged in manufacturing, 25 in engineering and engineering support functions, and 99 in selling, general and administrative functions.

The backlog for the Mobile Asphalt Paving Group segment at December 31, 2004 and 2003 was approximately $5,363,000 and $3,134,000, respectively.

The Underground Group consists of two manufacturing companies, Trencor, Inc., with its manufacturing facility located in Loudon, Tennessee ("Trencor", which does business as "Astec Underground") and American Augers, Inc., located in West Salem, Ohio ("American Augers"). These two business units design, engineer and manufacture a complete line of trenching equipment, directional drills, and auger boring machines, as well as, the downhole tooling to support these units for the underground construction market.

All trenchers are manufactured by Trencor in Loudon, Tennessee and all trenchless equipment is manufactured by American Augers in West Salem, Ohio. The Loudon facility produces 18 models of trenchers and mining machines, while the West Salem facility produces 28 models of trenchless equipment. In addition to these product models, each facility produces numerous attachments and tools for the equipment.

Trencor's trenching equipment, with the ability to cut a trench 35 feet deep and 8 feet wide through solid rock in a single pass, is among the toughest in the world. Utilizing a unique mechanical power train, Trencor machines are used to trench pipelines, lay fiber optic cable, cut irrigation ditches, insert highway drainage materials, and more. Trencor also makes foundation trenchers used in areas where drilling and blasting are prohibited. Trencor also manufactures a side-cutting rock saw, which permits trenching alongside vertical objects such as fences, guardrails, and rock wall in mountainous terrain. The rock saw is used for laying water and gas lines, fiber optic cable, as well as constructing highway drainage systems, among other uses.

Four Road Miner® models are available with an attachment that allows them to cut a path up to thirteen and a half feet wide and five feet deep on a single pass. The Road Miner® has applications in the road construction industry and in mining and aggregate processing operations.

During 2002, Trencor designed and developed the Surface Miner, a maneuverable, 1650-horsepower miner that can cut through rock 10 feet wide and up to 26 inches deep in a single pass. When equipped with a GPS unit and the automatic grade and slope system, the miner allows road construction contractors to match the exact specifications of a survey plan.

American Augers designs, manufactures, markets and sells a wide range of trenchless equipment. Today, American Augers is one of the largest manufacturers of auger boring machines in the world, designing and engineering state-of-the-art boring machines, directional drills and fluid/mud systems used in the underground construction or trenchless market. American Augers has one of the broadest product lines in the industry. American Augers serves customers throughout the world that operate in the sewer, power, fiber-optic telecommunication, electric, oil and gas, and water industries.

Trencor and American Augers market their products domestically through direct sales representatives and a dealer network, as well as internationally through both direct sales, independent dealers and sales agents. The Underground Group has approximately four direct sales associates who focus on the large machines, seven associates who focus on smaller drills and trenchers sold exclusively through a dealer network, four associates who focus solely on international, and two associates focused on all markets.

Both Trencor and American Augers maintain excellent relationships with suppliers and have experienced minimal turnover. The purchasing group has developed partnering relationships with many of the Company's key vendors to improve "just-in-time" delivery and thus lower inventory. Steel is the predominant raw material used to manufacture the products of the Underground Group, and is normally readily available. Components used in the manufacturing process include engines, hydraulic motors and pumps, gearboxes, power transmissions and electronics systems.

Competition for sales of trenching, excavating, auger boring, directional drilling, and fluid/mud equipment includes Charles Machine Works (Ditch Witch), Tesmec, Vermeer and other smaller custom manufacturers.

At December 31, 2004, the Underground Group segment employed 334 individuals, of which 238 were engaged in manufacturing, 34 in engineering and 62 in selling, general and administrative functions.

The backlog for the Underground Group segment at December 31, 2004 and 2003 was approximately $5,222,000 and $8,349,000, respectively

This category consists of the Company's business units that do not meet the requirements for separate disclosure as an operating segment. At December 31, 2004, these other operating units included Astec Insurance Company and Astec Industries, Inc., the parent company. Previously, this category also included Astec Transportation, Inc. and Astec Financial Services, Inc. During 2003, the Company liquidated the assets of Astec Transportation, Inc. This former subsidiary both owned and leased over-the-road tractors and trailers for delivery of the Company's large equipment to its customers. Currently, equipment is delivered primarily using common carriers independent of the Company. During 2003, revenues in this category were derived predominantly from operating leases, installment loans and other financial products that were offered by Astec Financial Services, Inc. As discussed earlier, on December 31, 2002, the Company exited the equipment financing business conducted through Ast ec Financial Services, Inc., a wholly owned subsidiary of the Company. The Company continues to receive payments and service certain notes receivable of Astec Financial Services, Inc.

At December 31, 2004, the Other Business Units segment employed 24 individuals, all of which were engaged in general and administrative functions.

Although the Company has four reportable business segments, the following information applies to all operating segments of the Company.

None of the Company's operating segments operate within highly regulated industries. However, air pollution control equipment manufactured by the Company, principally for hot-mix asphalt plants, must comply with certain performance standards promulgated by the federal Environmental Protection Agency under the Clean Air Act applicable to "new sources" or new plants. Management believes that the Company's products meet all material requirements of such regulations and of applicable state pollution standards and environmental protection laws.

In addition, due to the size and weight of certain equipment the Company manufactures, the Company and its customers sometimes confront conflicting state regulations on maximum weights transportable on highways. Also, some states have regulations governing the operation of asphalt mixing plants and most states have regulations relating to the accuracy of weights and measures, which affect some of the control systems manufactured by the Company.

Compliance with these government regulations has no material effect on capital expenditures, earnings, or the Company's competitive position within the market.

At December 31, 2004, the Company and its subsidiaries employed 2,657 individuals, of which 1,894 were engaged in manufacturing, 227 in engineering, including support staff, and 536 in selling, administrative and management functions.

Other than the Telsmith and Osborn labor agreements described under the Employee subsection of the Asphalt and Mining Group, there are no other collective bargaining agreements applicable to the Company. The Company considers its employee relations to be good.

The Company manufactures many of the component parts and related equipment for its products, while several large components of their products are purchased "ready-for-use". Such items include engines, axles, tires and hydraulics. In many cases, the Company designs, engineers and manufactures custom component parts and equipment to meet the particular needs of individual customers. Manufacturing operations during 2004 took place at 15 separate locations. The Company's manufacturing operations consist primarily of fabricating steel components and the assembly and testing of its products to ensure that the Company achieves quality control standards.

The Company periodically conducts technical and service seminars, which are primarily for contractors, employees and owners of asphalt mixing plants. In 2004, approximately 600 representatives of contractors and owners of hot-mix asphalt plants attended seminars held by the Company in Chattanooga, Tennessee. These seminars, which are taught by Company management and employees, cover a range of subjects including technological innovations in the hot-mix asphalt, aggregate processing, paving, milling, and recycling markets.

The Company also sponsors executive seminars for the management of the customers of Astec, Heatec, CEI and Roadtec. Primarily, members of the Company's management conduct the various seminars, but outside speakers and discussion leaders are also utilized.

During 2004, service training seminars were also held at the Roadtec facility for approximately 300 outside customer service representatives. Telsmith conducts regular technical seminars for customers and dealers during the year at its facility in Mequon, Wisconsin. KPI and JCI jointly conduct an annual dealer appreciation event called DAD. The event offers the dealer organization a preview into future product, marketing and promotional programs targeted by KPI and JCI to help them be successful businesses. Along with this event, both companies provide local, regional and national sales and service dealer training programs.

Product training seminars for the directional drill and auger boring product lines were held at the Trencor facility in Loudon, Tennessee for approximately 35 employees of dealers and customers.

In addition to seminars, the Company publishes a number of technical bulletins detailing various technological and business issues relating to the asphalt industry.

The Company seeks to obtain patents to protect the novel features of its products. The Company and its subsidiaries hold 104 United States patents and 60 foreign patents. There are 11 United States and foreign patent applications pending.

The Company and its subsidiaries have approximately 69 trademarks registered in the United States including logos for Astec, Telsmith, Roadtec and Trencor, and the names ASTEC, TELSMITH, HEATEC, ROADTEC, TRENCOR, AMERICAN AUGERS, KOLBERG, JCI and PIONEER. Twenty-two trademarks are also registered in foreign countries, including Canada, Great Britain, Mexico, New Zealand, India and Italy. The Company has six United States and foreign trademark applications pending.

The Company dedicates substantial resources to engineering and product development. At December 31, 2004, the Company and its subsidiaries had 227 full-time individuals employed domestically in engineering and design capacities.

In the normal season trend, revenues are strongest during the first three quarters of the year with the fourth quarter consistently being the weakest of the quarters. Operations during the entire year in 2004 were significantly impacted by the various economic factors discussed in the following paragraphs.

As of December 31, 2004, the Company had a backlog for delivery of products at certain dates in the future of approximately $93,543,000. At December 31, 2003, the total backlog was approximately $75,880,000. The Company's contracts reflected in the backlog are not, by their terms, subject to termination. Management believes that the Company is in substantial compliance with all manufacturing and delivery timetables.

Each business segment operates in domestic markets that are highly competitive regarding price, service and product quality. While specific competitors are named within each business segment discussion, imports do not generally constitute significant competition for the Company in the United States. In international sales, however, the Company generally competes with foreign manufacturers that may have a local presence in the market the Company is attempting to penetrate.

In addition, asphalt and concrete are generally considered competitive products as a surface choice for new roads and highways. A portion of the interstate highway system is paved in concrete, but over 90% of all surfaced roads in the United States are paved with asphalt. Although concrete is used for some new road surfaces, asphalt is used for virtually all resurfacing, including the resurfacing of most concrete roads. Management does not believe that concrete, as a competitive surface choice, materially impacts the Company's business prospects.

Many of our customers depend substantially on government funding of highway construction and maintenance and other infrastructure projects. Any decrease or delay in government funding of highway construction and maintenance and other infrastructure projects could cause our revenues and profits to decrease. Federal government funding of infrastructure projects is usually accomplished through bills, which establish funding over a multi-year period. On September 30, 2003, the six-year federal-aid highway program, the Transportation Equity Act for the 21^st Century ("TEA-21"), expired. A six-year TEA-21 reauthorization bill is currently being negotiated by Congress. Legislation has been entered into to extend authorization of the funding through May 31, 2005. Short-term extensions are necessary to keep federal highway and transit funds flowing while Congress continues working to enact the six-year TEA-21 reauthorization measure. If the reauthorization measure is not enacted i nto law by the May 31, 2005 extension deadline and if further extensions are not entered into, highway funding may stop until such reauthorization bill or extensions are enacted. Even if entered into, the highway legislation may be revised in future congressional sessions and federal funding of infrastructure may be decreased in the future, especially in the event of an economic recession. In addition, Congress could pass legislation in future sessions, which would allow for the diversion of highway funds for other national purposes or could restrict funding of infrastructure projects unless states comply with certain federal policies.

Certain customers have financed purchases of our products through arrangements in which we are contingently liable for customer debt and for residual value guarantees. These obligations range from 7 to 84 months in duration. If our customers default on this debt, we will have to pay the agreed contingency to the lender on behalf of the customer. The financed equipment collateralizes the underlying debt and under contract terms can reduce the amount of our contingent liability in the case of customer default. In the event of customer default, recovery from the lender from the sale of collateral may not be sufficient to repay amounts paid by us related to contingent liabilities. Significant cash payments for which we are contingently liable could adversely affect our available operating funds.

A significant portion of our revenues relates to the sale of equipment that produces asphalt mix. A major component of asphalt is oil, and asphalt prices correlate with the price and availability of oil. A rise in the price of oil or a decrease in the availability of oil would increase the cost of producing asphalt, which would likely decrease demand for asphalt, resulting in decreased demand for our products. This would likely cause our revenues and profits to decrease. In fact, rising gasoline, diesel fuel and liquid asphalt prices during 2004 significantly increased the operating and raw material costs of our contractor and aggregate producer customers, reducing their profits and causing delays in some of their capital equipment purchases.

We were notified of and incurred steel price increases and steel surcharges beginning in early 2004. Factors contributing to the increased steel costs are: 1) China's strong economy and its increased steel consumption and purchase of U.S. scrap steel; 2) the weakened U.S. dollar's dissuasion of foreign steel exports to the U.S.; 3) shortages of coke and iron ore; and 4) increased demand for steel in Korea and the U.S. During early 2004, some types of steel were available on an allocation basis determined by prior year purchases, although currently needed steel is readily available. We are passing along a portion of the increased steel costs to our customers by way of surcharges and price increases. Continued significant steel cost increases, in addition to potential limitation of the steel supply by mills, could negatively impact our gross margins and financial results.

General economic downturns, including downturns in the commercial construction industry, could result in a material decrease in our revenues and operating results. In fact, we believe that the economic downturn and political uncertainty during 2004 negatively affected our expected revenue growth which increased the competitive pricing pressure in the market. Demand for many of our products, especially in the commercial construction industry, is cyclical. Sales of our products are sensitive to the states of the U.S., foreign and regional economies in general, and in particular, changes in commercial construction spending and government infrastructure spending. In addition, many of our costs are fixed and cannot be quickly reduced in response to decreased demand. The following factors could cause a downturn in the commercial construction industry:

• a decrease in the availability of funds for construction;
• labor disputes in the construction industry causing work stoppages;
• rising gas and fuel oil prices;
• rising steel prices and steel-up charges;
• rising interest rates;
• energy or building materials shortages; and
• inclement weather.

As of December 31, 2004, we were in compliance with the financial covenants contained in our credit agreement dated as of May 14, 2003, as amended. We may be unable to comply with the amended covenant or the other financial covenants in our credit facility. If such violations occur, the lenders could elect to pursue their contractual remedies under the credit facility, including requiring immediate repayment in full of all amounts outstanding. We may also be unable to secure adequate or timely replacement of financing to repay our lenders in the event of an unanticipated repayment demand.

We have completed ten acquisitions since 1994, one of which was disposed during 2004, and may acquire additional businesses in the future. We may be unable to achieve the benefits expected to be realized from our acquisitions. In addition, we may incur additional costs and our management's attention may be diverted because of unforeseen expenses, difficulties, complications, delays and other risks inherent in acquiring businesses, including the following:

• we may have difficulty integrating the financial and administrative functions of acquired businesses;
• acquisitions may divert management's attention from our existing operations;
• we may have difficulty in competing successfully for available acquisition candidates, completing future acquisitions or accurately estimating the financial effect of any businesses we acquire;
• we may have delays in realizing the benefits of our strategies for an acquired business;
• we may not be able to retain key employees necessary to continue the operations of the acquired business;
• acquisition costs may deplete significant cash amounts or may decrease our operating income;
• we may choose to acquire a company that is less profitable or has lower profit margins than our company; and
• future acquired companies may have unknown liabilities that could require us to spend significant amounts of additional capital.

We currently face strong competition in product performance, price and service. Some of our national competitors have greater financial, product development and marketing resources than we have. If competition in our industry intensifies or if our current competitors enhance their products or lower their prices for competing products, we may lose sales or be required to lower the prices we charge for our products. This may reduce revenue from our products and services, lower our gross margins or cause us to lose market share.

In the past, we have experienced negative margins on certain large, specialized aggregate systems projects. These large contracts included both existing and innovative equipment designs, on-site construction and minimum production levels. Since it can be difficult to achieve the expected production results during the project design phase, field testing and redesign may be required during project installation, resulting in added cost. In addition, due to any number of unforeseen circumstances, which can include adverse weather conditions, projects can incur extended construction and testing delays which can cause significant cost overruns. We may not be able to sufficiently predict the extent of such unforeseen cost overruns and may experience significant losses on specialized projects.

We manufacture heavy machinery, which is used by our customers at excavation and construction sites and on high-traffic roads. Any defect in, or improper operation of, our equipment can result in personal injury and death, and damage to or destruction of property, any of which could cause product liability claims to be filed against us. The amount and scope of our insurance coverage may not be adequate to cover all losses or liabilities we may incur in the event of a product liability claim. We may not be able to maintain insurance of the types or at the levels we deem necessary or adequate or at rates we consider reasonable. Any liabilities not covered by insurance could reduce our profitability or have an adverse effect on our financial condition.

Our hot-mix asphalt plants contain air pollution control equipment that must comply with performance standards promulgated by the Environmental Protection Agency. These performance standards may increase in the future. Changes in these requirements could cause us to undertake costly measures to redesign or modify our equipment or otherwise adversely affect the manufacturing processes of our products. Such changes could have a material adverse effect on our operating results.

Also, due to the size and weight of some of the equipment that we manufacture, we often are required to comply with conflicting state regulations on the maximum weight transportable on highways and roads. In addition, some states regulate the operation of our component equipment, including asphalt mixing plants and soil remediation equipment, and most states regulate the accuracy of weights and measures, which affect some of the control systems that we manufacture. We may incur material costs or liabilities in connection with the regulatory requirements applicable to our business.

We hold numerous patents covering technology and applications related to many of our products and systems, and numerous trademarks and trade names registered with the U.S. Patent and Trademark Office and in foreign countries. Our existing or future patents or trademarks may not adequately protect us against infringements, and pending patent or trademark applications may not result in issued patents or trademarks. Our patents, registered trademarks and patent applications, if any, may not be upheld if challenged, and competitors may develop similar or superior methods or products outside the protection of our patents. This could reduce demand for our products and materially decrease our revenues. If our products are deemed to infringe upon the patents or proprietary rights of others, we could be required to modify the design of our products, change the name of our products or obtain a license for the use of some of the technologies used in our products. We may be unable to do any of the foregoing in a timely manner, upon acceptable terms and conditions, or at all, and the failure to do so could cause us to incur additional costs or lose revenues.

Dr. J. Don Brock, our Chairman and President, is of significant importance to our business and operations. The loss of his services may adversely affect our business. In addition, our ability to attract and retain qualified engineers, skilled manufacturing personnel and other professionals, either through direct hiring or acquisition of other businesses employing such professionals, will also be an important factor in determining our future success.

In 2004, international sales represented approximately 24% of our total sales. We plan to continue to increase our presence in international markets. In connection with any increase in international sales efforts, we will need to hire, train and retain qualified personnel in countries where language, cultural or regulatory barriers may exist. Any difficulties in expanding our international sales may divert management's attention from our existing operations. In addition, international revenues are subject to the following risks:

• fluctuating currency exchange rates which can reduce the profitability of foreign sales;
• the burden of complying with a wide variety of foreign laws and regulations;
• dependence on foreign sales agents;
• political and economic instability of governments; and
• the imposition of protective legislation such as import or export barriers.

Our quarterly revenues, expenses and operating results have varied significantly in the past and are likely to vary significantly from quarter to quarter in the future. As a result, our operating results may fall below the expectations of securities analysts and investors in some quarters, which could result in a decrease in the market price of our common stock. The reasons our quarterly results may fluctuate include:

• general competitive and economic conditions;
• delays in, or uneven timing in, the delivery of customer orders;
• the introduction of new products by us or our competitors;
• product supply shortages; and
• reduced demand due to adverse weather conditions.

Period-to-period comparisons of such items should not be relied on as indications of future performance.

Our charter, bylaws and Tennessee law contain provisions that may delay, deter or inhibit a future acquisition or an attempt to obtain control of us. This could occur even if our shareholders are offered an attractive value for their shares or if a substantial number or even a majority of our shareholders believe the takeover is in their best interest. These provisions are intended to encourage any person interested in acquiring us or obtaining control of us to negotiate with and obtain the approval of our Board of Directors in connection with the transaction. Provisions that could delay, deter or inhibit a future acquisition or an attempt to obtain control of us include the following:

• having a staggered Board of Directors;
• requiring a two-thirds vote of the total number of shares issued and outstanding to remove directors other than for cause;
• requiring advanced notice of actions proposed by shareholders for consideration at shareholder meetings;
• limiting the right of shareholders to call a special meeting of shareholders;
• requiring that all shareholders entitled to vote on an action provide written consent in order for shareholders to act without holding a shareholders meeting; and
• being governed by the Tennessee Control Share Acquisition Act.

In addition, the rights of holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of our preferred stock that may be issued in the future and that may be senior to the rights of holders of our common stock. On December 22, 1995, our Board of Directors approved a Shareholder Protection Rights Agreement, which provides for one preferred stock purchase right in respect of each share of our common stock ("Rights Agreement"). These rights become exercisable upon a person or group of affiliated persons acquiring 15% or more of our then-outstanding common stock by all persons other than an existing 15% shareholder. This Rights Agreement also could discourage bids for the shares of common stock at a premium and could have a material adverse effect on the market price of our shares.
