PART I

General

Koppers Inc. (the “Company” or “Koppers”) is a global integrated producer of carbon compounds and treated wood products. The Company’s chemical products are used in a wide variety of end markets with applications in the aluminum, railroad, specialty chemical, utility, rubber and steel industries. The “Koppers” brand name has been associated with the carbon compounds and wood treating businesses for many years, and is well-recognized as a leader in these industries. The Company operates 37 production facilities with locations in the United States, Australasia, China, Europe and South Africa. The Company also maintains an indirect ownership interest in an additional facility in the United States through its domestic joint venture KSA (as defined herein). The Company recorded net sales and net income of $952.5 million and $11.3 million, respectively, for the twelve months ended December 31, 2004.

The Company operates two principal businesses, Carbon Materials & Chemicals and Railroad & Utility Products. During 2004, the Carbon Materials & Chemicals business and Railroad & Utility Products business accounted for 58.1% and 41.9% of net sales, respectively. The Carbon Materials & Chemicals business processes coal tar into a variety of products, including carbon pitch, creosote and phthalic anhydride, which are intermediate materials necessary in the production of aluminum, the pressure treatment of wood and the production of plasticizers and specialty chemicals, respectively. The Company believes that its primary carbon materials and chemicals products are essential components used in its customers’ production processes. For example, carbon pitch is necessary for the production of aluminum and the electric arc furnace steel-making process. The Company’s Railroad & Utility Products business is the largest North American supplier of treated wood products, such as railroad crossties and utility poles, to railroads and the electric and telephone utility industries. In 2004, railroad crosstie and related products sales comprised approximately 80% of the net sales of the Railroad & Utility Products business. Treated wood creates more durable structures that resist decay and reduce replacement costs.

The Company was formed in October 1988 as “Koppers Industries, Inc.” under the laws of the Commonwealth of Pennsylvania by management, Beazer, Inc. and KAP Investments, Inc. (“KAP”, a subsidiary of Koppers Australia Pty. Limited) (“Koppers Australia”) to facilitate the acquisition of certain assets of Koppers Company, Inc. in a management-led leveraged buyout that closed on December 29, 1988 (the “Acquisition”). Koppers Company, Inc., now known as Beazer East, Inc. (“Beazer East”, but referred to herein as “Old Koppers” for periods prior to the Acquisition) had been acquired in June 1988 by BNS Acquisitions, Inc., a wholly owned indirect subsidiary of Beazer PLC, now known as Beazer Limited (“Beazer Limited”). Effective February 24, 2003 the Company changed its name to Koppers Inc. to reflect the global and diversified nature of the Company’s businesses.

Subsidiary of KI Holdings Inc.

On November 12, 2004, KI Holdings Inc. (“KI Holdings”) was incorporated. On November 18, 2004, all of the common and preferred stock of Koppers Inc. was converted into shares of common and preferred stock of KI Holdings and KI Holdings issued and sold $203.0 million aggregate principal amount at maturity ($125.5 million gross proceeds) 9 7/8% Senior Discount Notes due 2014 (the “Holdings Notes”). A portion of the cash proceeds was used to pay a $95 million dividend to KI Holdings’ stockholders. The approximately $25.5 million remainder was retained for general corporate purposes, which could include dividends, acquisitions, or working capital requirements. KI Holdings has no direct operations and no significant assets other than the stock of the Company. It depends on dividends from the earnings of the Company and its subsidiaries to generate the funds necessary to meet its financial obligations, including payments of principal, interest, and other amounts on the Holdings Notes. The terms of Koppers’ senior secured credit facility prohibit Koppers from paying dividends and otherwise transferring assets except for certain limited dividends. Further, the terms of the indenture governing the Company’s Senior Secured Notes (as described herein) significantly restrict the Company from paying dividends and otherwise transferring assets to KI Holdings.

Industry Overview

The Company believes that its two principal businesses are substantially affected by demand for aluminum and by railroad track maintenance. Worldwide aluminum production increased 6.4% to 29.8 million metric tons in 2004 from 28.0 million metric tons in 2003, and is estimated to grow to 31.6 million metric tons in 2005, for a compound annual growth rate of 6.3% since 2003. Carbon pitch requirements for the aluminum industry are estimated to be approximately 3.1 million metric tons in 2005, up from 2.5 million metric tons in 2004.

Coal tar is a by-product generated through the processing of coal into coke for use in steel and iron manufacturing. The Company produces and distributes a variety of intermediate chemical products derived from the coal tar distillation

process, including the co-products of the distillation process. During the distillation process, heat and vacuum are utilized to separate coal tar into three primary components: carbon pitch (approximately 50%), creosote oils (approximately 30%) and chemical oils (approximately 20%). Because all coal tar products are produced in relatively fixed proportion to carbon pitch, the level of carbon pitch consumption generally determines the level of production of other coal tar products. Three major markets served by the Carbon Materials & Chemicals business are the aluminum, wood preservation and chemical industries.

Approximately 92% of the Company’s U.S. creosote production is supplied to the Company’s Railroad & Utility Products business. Management estimates the North American market for creosote to be approximately 500 million pounds. Growth in this market is directly linked to the track maintenance programs of the Class 1 railroads. In 2005, the total market for creosote is expected to remain consistent with 2004 levels. The North American phthalic anhydride industry has production capacity of approximately 1.2 billion pounds and is a feedstock for plasticizers, unsaturated polyester resins, alkyd resins and other miscellaneous chemicals.

The North American railroad crosstie market is a mature market with approximately 20 million replacement crossties purchased during 2004. Historically, investment trends in track maintenance by domestic railroads have been linked to general economic conditions in the railroad industry. During the past several years, domestic railroads have underinvested in track maintenance due to the recession and a focus on capital equipment programs, such as investments in locomotives. Recently, the Class 1 railroads have increased their spending on track maintenance, which has caused an increase in demand for railroad crossties. However, a Class 1 customer of the Company has indicated they expect to reduce their volume requirements from the Company during 2005.

The U.S. market for treated wood utility pole products is characterized by a large number of small producers selling into a price-sensitive industry. The utility pole market is highly fragmented domestically with over 200 investor-owned electric and telephone utilities and 2,800 smaller municipal utilities and rural electric associations. Approximately 2.2 million utility poles are purchased annually in the United States, with a smaller market in Australia.

Carbon Materials & Chemicals

The Company’s Carbon Materials & Chemicals business manufactures five principal products: (a) carbon pitch, used in the production of aluminum and steel; (b) phthalic anhydride, used in the production of plasticizers and polyester resins; (c) creosote, used in the treatment of wood; (d) carbon black (and carbon black feedstock), used in the manufacture of rubber tires; and (e) furnace coke, used in steel production. Carbon pitch, phthalic anhydride, creosote and carbon black feedstock are produced through the distillation of coal tar, a by-product of the transformation of coal into coke. The Carbon Materials & Chemicals business’ profitability is impacted by its cost to purchase coal tar in relation to its prices realized for carbon pitch, phthalic anhydride, creosote and carbon black. The Company has three tar distillation facilities in the United States, one in Australia, one in China, one in Denmark and two in the United Kingdom, strategically located to provide access to coal tar and to facilitate better service to the Company’s customers with a consistent supply of high-quality products. For 2004, 2003 and 2002, respectively, principal products comprised the following percentages of net sales for Carbon Materials & Chemicals (excluding intercompany sales): (i) carbon pitch, 36%, 38% and 39%; (ii) phthalic anhydride, 14%, 12% and 12%; (iii) carbon black (and carbon black feedstock), 9%, 10% and 9%; (iv) furnace coke, 9%, 8% and 9%; (v) naphthalene, 5%, 4% and 3%; and (vi) creosote, 3%, 4% and 5%.

The Company believes it has a strategic advantage over its competitors based on its ability to access coal tar from many global suppliers and subsequently blend such coal tars to produce carbon pitch with the consistent quality important in the manufacturing of quality anodes for the aluminum industry. The Company’s eight coal tar distillation facilities, four of which have port access, and three carbon pitch terminals give Koppers the ability to offer customers multiple sourcing and a consistent supply of high quality products. In anticipation of potential reductions of U.S. coke capacity, the Company has secured coal tar supply through long-term contracts and acquisitions.

Over 75% of the Company’s carbon pitch is sold to the aluminum industry under long-term contracts typically ranging from three to four years, many with provisions for periodic pricing reviews. Demand for carbon pitch generally has fluctuated with production of primary aluminum. However, global restructuring in the electrode and aluminum markets during the past several years has resulted in reduced volumes in domestic markets. Because all coal tar products are produced in relatively fixed proportion to carbon pitch, the level of carbon pitch consumption generally determines the level of production of other coal tar products. The commercial carbon industry, the second largest user of carbon pitch, uses carbon pitch to produce electrodes and other specialty carbon products for the steel industry. There are currently no known viable substitutes for carbon pitch in the production of carbon anodes used in the aluminum production process.

Creosote is used in the wood preservation industry as a preservative for railroad crossties and lumber, utility poles and piling. To the extent that creosote cannot be sold for use in treating wood products, distillate oils are sold into the carbon black market rather than being blended to creosote specifications.

Approximately 75% of the Company’s global creosote production was sold to its Railroad & Utility Products business in 2004. Railroad & Utility Products purchases substantially all of its creosote from the Carbon Materials & Chemicals business. Koppers is the only competitor in this market that is integrated in this fashion. The remainder of the Company’s creosote is sold to railroads or to other wood treaters. The Company has several major competitors in the creosote market.

The Company is also a 51% owner of a timber preservation chemicals business that operates throughout Australia, New Zealand, Southeast Asia, Japan and South Africa. Timber preservation chemicals are used to provide durability to timber products used in building/construction, agricultural and heavy-duty industrial markets. The most commonly used

chemicals are creosote, copper chrome arsenates, copper co-biocides, sapstain control products and light organic solvent preservatives.

Roofing pitch and refined tars are also produced in smaller quantities and are sold into the commercial roofing and pavement sealer markets, respectively.

Carbon black is manufactured in Australia at a carbon black facility using both petroleum oil and coal tar based feedstocks, which are subjected to heat and rapid cooling within a reactor. Additionally, tar-based carbon black feedstock is manufactured as a co-product of the tar distillation process and can be produced at the Company’s three domestic, one Australian, one Chinese and three European tar distillation facilities.

Chemical oils resulting from the distillation of coal tars are further refined by the Company into naphthalene, which is the primary feedstock used by the Company for the production of phthalic anhydride. The primary markets for phthalic anhydride are in the production of plasticizers, unsaturated polyester resins and alkyd resins. Naphthalene is also sold into the industrial sulfonate market for use as dispersants in the concrete additive and gypsum board markets. Additional end uses include oil field additives, agricultural emulsifiers, synthetic tanning agents and dyestuffs.

On a worldwide basis, naphthalene and orthoxylene, a refined petroleum derivative, are both used as feedstock for the production of phthalic anhydride. The Company is the only North American phthalic anhydride producer capable of utilizing both orthoxylene and naphthalene for this production. Its ability to utilize naphthalene as a by-product of coal tar distillation gives it a stable feedstock. The Company believes that its ability to utilize naphthalene gives it a lower-cost feedstock for the production of phthalic anhydride since historically its cost for naphthalene has been lower than the Company’s cost to purchase orthoxylene. However, prior to 2004 there were difficult market conditions and corresponding low operating rates for most producers. Market conditions for phthalic anhydride improved in 2004 and are expected to remain stable during 2005.

Furnace coke is a carbon and fuel source required in the manufacturing of steel. Coal, the primary raw material, is carbonized in oxygen-free ovens to obtain the finished product. Coke manufacturers are either an integrated part of a steel company or, as in the Company’s case, operate independently and are known as “merchant producers.”

The Company’s coke business consists of one production facility located in Monessen, Pennsylvania, which produces furnace coke. The plant consists of two batteries with a total of 56 ovens and has a total capacity of approximately 350,000 tons of furnace coke per year. All of the ovens were rebuilt in 1980 and 1981, which, together with recent improvements, make the Monessen facility one of the most modern coking facilities in the United States.

Before the expiration of the related tax law on December 31, 2002, the Monessen facility qualified for a tax credit based on its production of coke as a non-conventional fuel and the sale thereof to unrelated third parties. The tax credit generated per ton of coke was tied to a per-barrel of oil equivalent determined on a British Thermal Unit basis and adjusted annually for inflation. The value of this tax credit per ton of coke was approximately $28.00 in 2002. In December 1999 the Company entered into a transaction with a third party which resulted in substantially all tax credits generated as a result of the production and sale of coke at the Company’s Monessen facility being transferred to the third party. In 2003 and 2002, the Company earned $0.1 million and $9.8 million, respectively, for the transfer of tax credits (the 2003 amount was a retroactive inflation adjustment). The tax credits expired at the end of 2002. Prior to the Monessen transaction, the Company earned these credits.

The Carbon Materials & Chemicals business’ ten largest customers represented approximately 41%, 44% and 47% of the business’ net sales for 2004, 2003 and 2002, respectively. The Company has several major competitors in the carbon pitch market.

Coal tar is purchased from a number of outside sources as well as from the Monessen facility. Primary suppliers are United States Steel Corporation, International Steel Group, China Steel Chemical Corporation, Bluescope Steel (AIS) Pty. Limited, OneSteel Manufacturing Pty. Ltd., Corus Group PLC and Wheeling-Pittsburgh Steel Corporation.

Management believes that its ability to source coal tar and carbon pitch from overseas markets through its foreign operations, as well as its research of petroleum feedstocks, will assist in securing an uninterrupted supply of carbon pitch feedstocks.

In 1999, Koppers entered into a joint venture agreement with Tangshan Iron & Steel Co. (“TISCO”) to rehabilitate and operate a tar distillation facility in China. The joint venture, Koppers (China) Carbon and Chemical Co., Limited (“Koppers China”), is 60% owned by the Company and began production of coal tar products in 2001. On January 1, 2004, the Company resumed operating control of Koppers (China) Carbon and Chemical Co., Limited and began to

consolidate its results in the first quarter of 2004. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Other Financial Matters.”

Railroad & Utility Products

Koppers markets treated wood products primarily to the railroad and public utility markets, primarily in the United States and Australasia. The Railroad & Utility Products business’ profitability is influenced by the demand for railroad products and services by Class 1 railroads, demand for transmission and distribution poles by electric and telephone utilities and its cost to procure wood. For the year ended December 31, 2004, sales of railroad products and services represented approximately 80% of the Railroad & Utility Products business’ net sales. Railroad products include items such as crossties, switch ties and various types of lumber used for railroad bridges and crossings. Utility products include transmission and distribution poles for electric and telephone utilities and piling used in industrial foundations, docks and piers. The Railroad & Utility Products business operates 19 wood treating plants, one specialty trackwork facility, one co-generation facility and pole distribution yards located throughout the United States and Australia. The Company’s network of plants is strategically located near timber supplies to enable the Company to access raw materials and service customers effectively. In addition, the Company’s crosstie treating plants typically abut railroad customers’ track lines, and its pole distribution yards are typically located near its utility customers.

The Railroad & Utility Products business’ largest customer base is the Class 1 railroad market, which buys 79% of all crossties produced in the United States. Koppers has also been expanding key relationships with some of the approximately 550 short-line and regional rail lines. The railroad crosstie market is a mature market with approximately 20 million replacement crossties purchased during 2004, representing an estimated $560 million in sales. The Company currently has contracts with six of the seven North American Class 1 railroads and has enjoyed long-standing relationships with this important customer base. These relationships have been further strengthened recently due to Koppers’ ability to absorb additional treating volumes into its existing infrastructure, with such additional volumes resulting from the exit of a major competitor from the wood treating business. The Company intends to focus on integrating this additional treating volume while capitalizing on its relationships with the railroads by offering an expanded list of complementary product and service offerings that the railroads may be interested in outsourcing.

Hardwoods, such as oak and other species, are the major raw materials in wood crossties. Hardwood prices, which account for approximately 68% of a finished crosstie’s cost, fluctuate with the demand from competing hardwood lumber markets, such as oak flooring, pallets and other specialty lumber products. Normally, raw material price fluctuations are passed through to the customer according to the terms of the applicable contract. Weather conditions can be a factor in the supply of raw material, as unusually wet conditions may make it difficult to harvest timber.

In the United States, hardwood lumber is procured by Koppers from hundreds of small sawmills throughout the northeastern, midwestern, and southern areas of the country. The crossties are shipped via rail car or trucked directly to one of the Company’s twelve crosstie treating plants, all of which are on line with a major railroad. The crossties are either air-stacked for a period of six to twelve months or artificially dried by a process called boultonizing. Once dried, the crossties are pressure treated with creosote, a product of the Company’s Carbon Materials & Chemicals business.

The Company’s top ten Railroad & Utility Products accounts comprised approximately 69%, 70% and 66% of Railroad & Utility Products’ net sales for 2004, 2003 and 2002, respectively, and many are serviced through long-term contracts ranging from one to seven years on a requirements basis. There are several principal regional competitors in this market.

The Company believes that the threat of substitution for the wood crosstie is low due to the higher cost of alternative materials. Concrete crossties, however, have been identified by the railroads as a feasible alternative to wood crossties in limited circumstances. In 1991, Koppers acquired a 50% partnership interest in KSA Limited Partnership, a concrete crosstie manufacturing facility in Portsmouth, Ohio, in order to take advantage of this growth opportunity. In 2004, an estimated 0.7 million concrete crossties, or 4% of total tie insertions, were installed by Class 1 railroads. The Company believes that concrete crossties will continue to command approximately this level of market share. While the cost of material and installation of a concrete crosstie is much higher than that of a wood crosstie, the average lives of wood and concrete crossties are similar.

Utility poles are produced mainly from softwoods such as pine and fir in the United States and from hardwoods of the eucalyptus species in Australia. Most of these poles are purchased from large timber owners and individual landowners and shipped to one of the Company’s pole-peeling facilities. While crossties are treated exclusively with creosote, the Company treats poles with a variety of preservatives, including pentachlorophenol, copper chrome arsenates, and creosote.

Table of Contents

In the United States the market for utility pole products is characterized by a large number of small, highly competitive producers selling into a price-sensitive industry. The utility pole market is highly fragmented domestically, with over 200 investor-owned electric and telephone utilities and 2,800 smaller municipal utilities and rural electric associations. Approximately 2.25 million poles are purchased annually in the United States, with a smaller market in Australia. In recent years the Company has seen the Company’s utility pole volumes decrease due to utility industry deregulation, its impact on maintenance programs, and overcapacity in the pole treating business. The Company expects demand for utility poles to remain at low levels. In Australia, in addition to utility poles, the Company markets smaller poles to the agricultural, landscape and vineyard markets.

During 2004, sales of pole products accounted for approximately 20% of Railroad & Utility Products’ net sales. The Company has nine principal competitors in the utility products market. There are few barriers to entry in the utility products market, which consists of regional wood treating companies operating small to medium-size plants and serving local markets.

Equity Investments

Domestic Joint Venture: KSA

KSA, located in Portsmouth, Ohio, produces concrete crossties, a complementary product to the Company’s treated wood crosstie business. The Company owns 50% of KSA, with the other 50% owned by subsidiaries of Lehigh Cement Company. KSA entered into a contract with a major customer in 2000 to supply a minimum of 450,000 concrete ties over a period of five years. KSA also provides concrete turnouts, used in rail traffic switching, and used crosstie rehabilitation.

Research and Development

As of December 31, 2004, the Company had 11 full-time employees engaged in research and development and technical service activities. The Company’s research efforts are directed toward new product development regarding alternate uses for coal tar and technical service efforts to promote the use of creosote. The Company believes the research and technical efforts provided in these areas are adequate to maintain a leadership position in the technology related to these products. Expenditures for research and development for 2004, 2003 and 2002 were $2.2 million, $2.3 million and $2.9 million, respectively.

Technology and Licensing

In 1988, Koppers acquired certain assets from Old Koppers including the patents, patent applications, trademarks, copyrights, transferable licenses, inventories, trade secrets, and proprietary processes used in the businesses acquired. The most important trademark acquired was the name “Koppers.” The association of the name with the chemical, building, wood preservation and coke industries is beneficial to the Company, as it represents longstanding, high-quality products.

Environmental Matters

The Company’s operations and properties are subject to extensive federal, state, local and foreign environmental laws and regulations relating to protection of the environment and human health and safety including those concerning the treatment, storage and disposal of wastes, the investigation and remediation of contaminated soil and groundwater, the discharge of effluents into waterways, the emission of substances into the air, as well as various health and safety matters. Environmental laws and regulations are subject to frequent amendment and have historically become more stringent. The Company has incurred and could incur in the future significant costs as the result of a failure to comply with, and liabilities under, environmental laws and regulations, including cleanup costs, civil and criminal penalties, injunctive relief and denial or loss of, or imposition of significant restrictions on, environmental permits. In addition, the Company has been, and could in the future be, subject to suit by private parties in connection with alleged violations of or liabilities under environmental laws and regulations.

For the last three years, the Company’s annual capital expenditures in connection with environmental control facilities averaged approximately $5.5 million, and annual operating expenses for environmental matters, excluding depreciation, averaged approximately $9.1 million. Management estimates that capital expenditures in connection with matters relating to environmental control facilities will be approximately $12 million for 2005. The Company believes that it will have continuing significant expenditures associated with compliance with environmental laws and regulations and, to the extent not covered by insurance or available recoveries under third-party indemnification arrangements, for present and future remediation efforts at plant sites and third-party waste sites and other liabilities associated with environmental

Stockholders’ Agreement

Prior to November 2004, the Company was a party to a stockholders’ agreement. When the common and preferred stock of Koppers Inc. was converted into common and preferred stock of KI Holdings Inc. as noted above, the stockholders’ agreement of Koppers Inc. was amended to provide for the transfer of the terms and conditions of the stockholders’ agreement from Koppers Inc. to KI Holdings Inc. The management investors were a group of approximately 120 individual stockholders with various ownership interests in the common stock and collectively comprising 100% of the total outstanding shares of the common stock of the Company. Each management investor was an officer, director, or current or former employee of either Koppers or one of its subsidiaries.

The stockholders’ agreement had set forth supermajority voting requirements for the Board of Directors for certain matters, including the issuance of additional stock, mergers, consolidations, acquisitions, significant asset sales, and the incurrence of material indebtedness. Majority owner Saratoga Partners III, L.P. (“Saratoga”) was entitled to nominate a majority of the Board of Directors. Prior to February 27, 2004 the stockholders’ agreement required the Company to redeem shares upon a management investor’s ceasing for any reason to be employed by the Company. On February 27,

The following table sets forth certain sales and operating data, net of all inter-segment transactions, for the Company’s businesses for the periods indicated:

Comparison of Results of Operations for the Years Ended December 31, 2004 and 2003.

Net Sales. Net sales for the year ended December 31, 2004 were higher than 2003 as both business segments reported sales increases. Net sales for Carbon Materials & Chemicals increased due in part to approximately $30.4 million in sales from Australian and European operations as a result of the strength of these foreign currencies relative to the dollar. Also, the consolidation of Koppers China as of January 1, 2004 resulted in incremental sales of $25.5 million compared to the prior year. Additionally, sales pricing for phthalic anhydride and furnace coke increased 27% and 25%, respectively, which more than offset reduced volume and pricing for carbon black and carbon black feedstock of 15% and 5%, respectively. Net sales for Railroad & Utility Products increased compared to the prior year due primarily to increases of 3% and 7% in volumes and prices, respectively, for railroad crossties. The increase in volumes for railroad crossties was due in part to the exit from the wood treating business of the Company’s largest competitor.

Gross Margin After Depreciation and Amortization. As a percent of net sales, gross profit after depreciation and amortization increased for both Carbon Materials & Chemicals and Railroad & Utility Products. Gross margin for Carbon Materials & Chemicals increased due to $4.7 million of charges for asset retirement obligations in 2003 due to restructuring, coupled with $1.7 million of gains on settlements of asset retirement obligations during 2004. Gross margin for Carbon Materials & Chemicals also increased due to the increases in pricing for phthalic anhydride and furnace coke noted above. These increases more than offset a $0.5 million charge for the settlement of a contract dispute with a customer. Gross margin for Railroad & Utility Products increased due primarily to higher volumes for railroad crossties.

Depreciation and Amortization. Depreciation and amortization for 2004 decreased compared to the prior year due primarily to restructuring activities in 2003 which reduced depreciation expense that would have been incurred on impaired assets by approximately $1.2 million in 2004.

Selling, General and Administrative Expense. Selling, general and administrative expense as a percent of net sales decreased primarily as a result of higher sales in the current year, plus $1.4 million of bad debt write-offs and $1.3 million of severance charges in the prior year, which offset an increase of $3.0 million as a result of foreign exchange rates and an increase of $2.2 million of management incentive and restricted stock compensation expense in the current year.

Restructuring and Impairment Charges. During the fourth quarter of 2003 the Company determined that capacity rationalization was required in its U.S. Carbon Materials & Chemicals business to increase competitiveness. Accordingly, in December 2003 Koppers ceased production at its carbon materials facility in Woodward, Alabama, resulting in a restructuring charge to fourth quarter pre-tax income of $3.1 million. Additionally, during the fourth quarter of 2003 the Company concluded that its carbon materials port operation in Portland, Oregon was an impaired facility based on its current and long-term economic prospects. The impairment charge for this facility resulted in a charge to fourth quarter pre-tax income of $3.1 million. The Company also incurred a $1.0 million charge for the impairment of certain storage tanks which were permanently idled due to reduced demand for carbon materials products in U.S. markets. In September 2003, the Company closed its Logansport, Louisiana wood treating plant due to deteriorating local market conditions. The closure resulted in a $1.3 million restructuring charge in the third quarter. The Company believes the U.S. market for wood treated utility poles suffers from over-capacity, and will continue to evaluate future productivity and cost reduction initiatives in this and all of its other businesses.

Interest Expense. Interest expense decreased despite higher debt levels in 2004 due to the refinancing of the Company’s debt in 2003 which resulted in $14.2 million of additional interest expense for a call premium, the write-off of deferred financing costs, and additional interest for the period between the receipt of proceeds from the Senior Secured Notes and the redemption of the Old Notes.

Income Taxes. The Company’s effective income tax rate for the year ended December 31, 2004 increased due primarily to the composition of earnings among U.S. and foreign operations.

Cumulative Effect of Accounting Change. Effective January 1, 2003, the Company changed its method of accounting for asset retirement obligations in accordance with FASB Statement No. 143, Accounting for Asset Retirement Obligations. Previously, the Company had not been recognizing amounts related to asset retirement obligations. Under the new accounting method, Koppers now recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The cumulative effect of the change on prior years resulted in a charge to income of $18.1 million, net of income taxes of $11.7 million.

Net Income. Net income for 2004 compared to the same period last year increased due primarily to the January 1, 2003 adoption of SFAS No. 143, Accounting for Asset Retirement Obligations, which resulted in a cumulative effect adjustment for 2003. Additionally, net income before the cumulative effect of accounting change was higher in 2004 due to higher volumes and pricing of certain products, $2.7 million of net income from the consolidation of China which included improved operating results and $1.7 million of net income as a result of higher exchange rates, while net income in 2003 was adversely affected due to certain restructuring, impairment and related charges.

Comparison of Results of Operations for the Years Ended December 31, 2003 and 2002.

Net Sales. Net sales for the year ended December 31, 2003 were higher than 2002 as both business segments reported sales increases. Net sales for Carbon Materials & Chemicals increased due primarily to approximately $39.8 million in sales from Australian and European operations as a result of the strength of these foreign currencies relative to the dollar. Additionally, sales volumes and pricing for phthalic anhydride increased by 7% and 8%, respectively, while a reduction in volumes for furnace coke of 11% more than offset an increase in pricing for furnace coke of 8%. Net sales for Railroad & Utility Products increased compared to the prior year due primarily to a 12% increase in prices for railroad crossties which more than offset a 5% reduction in volumes for railroad crossties.

Gross Margin After Depreciation and Amortization. As a percent of net sales, gross profit after depreciation and amortization decreased for both segments. Gross margin for Carbon Materials & Chemicals decreased primarily as a result of approximately $3.1 million of accelerated asset retirement obligations and $1.4 million for the settlement of a lease obligation, all related to the restructuring of the U.S. Carbon Materials & Chemicals operations (see “—Restructuring and Impairment Charges”). These items more than offset the profit realized as a result of the pricing increase for furnace coke noted above and a reversal to profit of approximately $0.7 million of environmental reserves as a result of a reassessment of exposure at one of the Company’s facilities. Gross margin as compared to the prior year was also impacted by an increase of approximately $1.7 million in insurance expense for Carbon Materials & Chemicals as a result of lower expense in the prior year due to favorable loss experience. Gross margin for Railroad & Utility Products decreased due to $1.6 million of accelerated asset retirement obligations related to the closure of the Logansport facility. Additionally, insurance expense for Railroad & Utility Products increased approximately $1.7 million as a result of lower expense in the prior year due to favorable loss experience. These additional costs more than offset the effect of the increase in prices for railroad crossties noted above.

Depreciation and Amortization. Depreciation and amortization for 2003 increased compared to the prior year due to the adoption of SFAS 143, “Accounting for Asset Retirement Obligations,” which resulted in an increase of $3.3 million, and an additional $1.3 million as a result of higher foreign exchange rates which resulted in higher depreciation expense in Australian and European operations.

Selling, General and Administrative Expense. Selling, general and administrative expense as a percent of net sales increased primarily as a result of approximately $1.3 million in severance charges, $1.4 million of bad debt expense, $2.0 million of higher legal and consulting costs, and $1.5 million of reduced expense in the prior year as a result of retiree health insurance settlements.

Restructuring and Impairment Charges. During the fourth quarter of 2003 the Company determined that capacity rationalization was required in its U.S. Carbon Materials & Chemicals business to increase competitiveness. Accordingly, in December 2003 Koppers ceased production at the Company’s carbon materials facility in Woodward, Alabama, resulting in a restructuring charge to fourth quarter pre-tax income of $3.1 million. The Woodward facility generated approximately $27.5 million of revenue during 2003. Additionally, during the fourth quarter of 2003 the Company concluded that its carbon materials port operation in Portland, Oregon was an impaired facility based on its current and long-term economic prospects. The impairment charge for this facility resulted in a charge to fourth quarter pre-tax income of $3.1 million. The Company also incurred a $1.0 million charge for the impairment of certain storage tanks which were permanently idled due to reduced demand for carbon materials products in U.S. markets. In September 2003, the Company closed its Logansport, Louisiana wood treating plant due to deteriorating local market conditions. The closure resulted in a $1.3 million restructuring charge in the third quarter. The Company believes the U.S. market for wood treated utility poles suffers from over-capacity, and will continue to evaluate future productivity and cost reduction initiatives in this and all of its other businesses.

Other Income. Other income consists of the energy tax credits as a result of the transaction at the Company’s Monessen, Pennsylvania coke facility. The reduction for 2003 was due to the expiration of the tax credits at the end of 2002.

Interest Expense. Interest expense increased due to a call premium of $5.8 million on the Company’s old bonds, the write-off of deferred financing charges of $6.4 million, and additional interest of $2.0 million for the period between the receipt of proceeds from the Senior Secured Notes and the redemption of the Old Notes. (See “—Liquidity and Capital Resources.”)

Income Taxes. The Company’s effective income tax rate for the year ended December 31, 2003 decreased due primarily to domestic pre-tax losses, which resulted in an increase in foreign tax expense as a percentage of total taxes. Due to the Company’s legal structure, foreign tax credits are not fully available to offset taxable income generated by Australian operations.

Cumulative Effect of Accounting Change. Effective January 1, 2003, the Company changed its method of accounting for asset retirement obligations in accordance with FASB Statement No. 143, Accounting for Asset Retirement Obligations. Previously, the Company had not been recognizing amounts related to asset retirement obligations. Under the new accounting method, the Company now recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of a fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The cumulative effect of the change on prior years resulted in a charge to income of $18.1 million, net of income taxes of $11.7 million.

Net Income. Net income for 2003 compared to the same period last year decreased due to (i) restructuring, impairment and capacity rationalization charges in the U.S. segments as a result of weakened business conditions in the carbon materials and utility pole businesses; (ii) the write-off of deferred financing charges and the payment of a call premium due to the refinancing of the Company’s debt; (iii) an increase in bad debt expense; (iv) a decrease in other income due to the expiration of the energy tax credits; and (v) the adoption of SFAS No. 143, Accounting for Asset Retirement Obligations, which resulted in a cumulative effect adjustment.

Liquidity and Capital Resources

On November 12, 2004, KI Holdings Inc. was incorporated. On November 18, 2004, all of the common and preferred stock of Koppers Inc. was converted into shares of common and preferred stock of KI Holdings Inc.

On November 18, 2004, KI Holdings Inc. issued and sold $203.0 million aggregate principal amount at maturity ($125.5 million gross proceeds) 9 ⁷/8% Senior Discount Notes due 2014 (“Holdings Notes”). A portion of the cash

15

Table of Contents

proceeds was used to pay a $95 million dividend to KI Holdings’ stockholders. The approximately $25.5 million remainder was retained for general corporate purposes, which could include dividends, acquisitions, or working capital requirements. KI Holdings has no direct operations and no significant assets other than the stock of Koppers Inc. It depends on the dividends from the earnings of Koppers and its subsidiaries to generate the funds necessary to meet its financial obligations, including payments of principal, interest and other amounts on the Holdings Notes. The terms of Koppers’ senior secured credit facility prohibit Koppers from paying dividends and otherwise transferring assets except for certain limited dividends. Further, the terms of the indenture governing the Senior Secured Notes significantly restrict Koppers from paying dividends and otherwise transferring assets to KI Holdings. For example, Koppers’ ability to make such payments under its indenture is governed by a formula based, in part, on 50% of its consolidated net income. In addition, as a condition to making such payments based, in part, on such formula, Koppers must have a ratio of EBITDA (as defined in the indenture governing Koppers Inc.’s Senior Secured Notes) to interest expense of at least 2.0 to 1.0, after giving effect to any such payments, and must not be in default under that indenture.

Koppers’ liquidity needs are primarily for debt service, working capital, capital maintenance and acquisitions. Koppers believes that its cash flow from operations and available borrowings under its bank credit facilities will be sufficient to fund its anticipated liquidity requirements for at least the next twelve months. In the event that the foregoing sources are not sufficient to fund its expenditures and service its indebtedness, Koppers would be required to raise additional funds.

As of December 31, 2004, the Company had $14.8 million of cash and cash equivalents and $31.4 million of unused revolving credit availability for working capital purposes after restrictions by various debt covenants and letter of credit commitments. As of December 31, 2004, $18.9 million of commitments were utilized by outstanding standby letters of credit.

Net cash provided by operating activities increased compared to the prior year as higher net income before cumulative effect of accounting change and an increase in the utilization of deferred taxes were partially offset by an increase in working capital in 2004 of $18.1 million compared to an increase in working capital in 2003 of $7.5 million, an $8.6 million increase in pension funding in 2004, and a $2.0 million payment for the extension of the indemnity agreement with Beazer (see “—Environmental and Other Liabilities Retained or Assumed by Others”).

Capital expenditures were higher than the prior year due primarily to an increase in capital expenditures in the U.S. carbon materials business.

Net cash used in financing activities in 2004 related to revolver borrowings of $49.9 million to provide for the payment of $33.4 million in dividends, the repayment of $8.0 million of the term loan, the purchase of $1.5 million of common stock, and the payment of $1.4 million of deferred financing costs. Net cash provided by financing activities in the prior year related to the issuance of $320 million of Senior Secured Notes to provide for the redemption of $175 million of notes due in 2007, a reduction in the amount of bank debt, payment of $48.1 million of dividends, $9.0 million of purchases of stock from retirees, and the payment of $16.1 million of deferred financing costs.

9  ^7/8% Senior Secured Notes due 2013

Koppers has issued and outstanding $320.0 million aggregate principal amount of 9 ⁷/8% Senior Secured Notes due 2013 (the “Senior Secured Notes”). Interest is payable semiannually in arrears on April 15 and October 15 of each year. The Senior Secured Notes are guaranteed, jointly and severally, on a senior secured basis by some of the Company’s current and future subsidiaries.

The Senior Secured Notes and subsidiary guarantees are senior obligations of Koppers and its subsidiary guarantors, respectively, and are secured by a second priority lien on and security interest in substantially all of the assets owned by Koppers and its subsidiary guarantors that secure Koppers’ obligations under its senior secured credit facilities.

The Senior Secured Notes include customary covenants that restrict, among other things, the ability to incur additional debt, pay dividends or make certain other restricted payments, incur liens, merge or sell all or substantially all of the assets or enter into various transactions with affiliates. Prior to October 15, 2006, Koppers may redeem up to 35% of the aggregate principal amount of the Senior Secured Notes at a redemption price of 109.875% of the principal amount thereof, plus accrued and unpaid interest to the date of such redemption, with funds raised in specified equity offerings. On or after October 15, 2008, Koppers may redeem some or all of the Senior Secured Notes at redemption prices specified in the indenture governing such notes, plus accrued and unpaid interest to the date of such redemption.

The terms of the indenture governing the Senior Secured Notes significantly restrict Koppers from paying dividends and otherwise transferring assets to KI Holdings. For example, Koppers’ ability to make such payments is governed by a

16

Table of Contents

formula based on 50% of its consolidated net income. In addition, as a condition to making such payments based on such formula, Koppers Inc. must have an EBITDA (as defined in the indenture governing the Senior Secured Notes) to consolidated interest expense ratio of at least 2.0 to 1.0. Notwithstanding such restrictions, the indenture permits an aggregate of $7.5 million of such payments to be made whether or not there is availability under the formula or conditions to its use are met, provided that at the time of such payment, no default shall have occurred and be continuing under that indenture.

The indenture governing the Senior Secured Notes has a covenant that limits the incurrence of additional indebtedness unless on the date of the incurrence of additional indebtedness the Consolidated Coverage Ratio (defined therein) will be, after giving effect to the incurrence thereof and the application of the proceeds thereof, greater than 2.0 to 1.0. The indenture defines Consolidated Coverage Ratio as the ratio of (a) the aggregate amount of EBITDA for the period of the most recent four consecutive fiscal quarters ending at least 45 days prior to the date of such determination to (b) Consolidated Interest Expense (defined therein) for such four fiscal quarters.

The Company is currently in compliance with all covenants in the indenture governing the Senior Secured Notes. Koppers anticipates continued compliance with these covenants. Failure to comply with the covenants contained in the indenture governing the Senior Secured Notes will result in an event of default. The indenture governing the Senior Secured Notes also contains various other events of default, including but not limited to those related to non-payment of principal, interest or fees; certain bankruptcy-related events; invalidity of liens; non-payment of certain legal judgments; and cross defaults with certain other indebtedness.

The covenants related to the revolving credit facility also include financial covenants that require Koppers to maintain certain financial ratios, including the following:

Subsidiary Pledges. The terms of the Senior Secured Notes provide that the collateral securing the Senior Secured Notes will never include the securities of any subsidiary to the extent the par value, book value as carried by the Company or the market value of the securities (the “Applicable Value”) is equal to or greater than 20% of the aggregate principal amount of the Senior Secured Notes outstanding (the “Collateral Threshold”). Rule 3-16 of Regulation S-X under the Securities Act of 1933 requires the presentation of a subsidiary’s stand-alone, audited financial statements if the subsidiary’s capital stock secures an issuer’s notes and the par value, book value or market value of the securities equals or exceeds the Collateral Threshold. The indenture governing the Senior Secured Notes and the security documents provide that the collateral will never include the capital stock of any subsidiary to the extent the Applicable Value of the securities is equal to or greater than the Collateral Threshold. As a result, Koppers will not be required to present separate financial statements of any of its subsidiaries under Rule 3-16.

17

Table of Contents

As a result of the provisions in the indenture and security documents relating to subsidiary securities, holders of the Senior Secured Notes may at any time in the future lose a portion of their security interest in the securities of any of the Company’s other subsidiaries if the Applicable Value of that stock were to become equal to or greater than the Collateral Threshold. As stated above, Applicable Value is defined as the greatest of book value, par value and market value of a subsidiary’s securities. Currently, all of the capital stock of all of the Company’s domestic subsidiaries and all of the Company’s subsidiaries other than 35% of the voting capital stock of Koppers Europe ApS constitute collateral for the Senior Secured Notes.

The Company has based its determination of which subsidiary’s capital stock currently constitutes collateral upon the book value, par value and estimated market value of the capital stock of each of its subsidiaries as of December 31, 2004 and the operations of these subsidiaries since that date. The Applicable Value for the capital stock of each of the Company’s subsidiaries is the greater of the book value and estimated market value, as the value of each subsidiary’s capital stock is nominal and therefore has not impacted the Company’s calculation of Applicable Value. The Net Fair Value and Net Book Value calculations each include an allocation of corporate debt to the subsidiaries. Set forth in the table below is the Applicable Value of each subsidiary’s capital stock as of December 31, 2004:

The Applicable Value of the capital stock of the Company’s subsidiaries did not exceed the Collateral Threshold as of December 31, 2004. Further, as there have been no significant changes in the operations of each of these subsidiaries since December 31, 2004, the Company has determined that the Applicable Value of the capital stock of each of these subsidiaries currently remains below the Collateral Threshold.

In respect of Koppers Delaware, Inc., Koppers Concrete Products, Inc. and Concrete Partners, Inc., the Applicable Value of their common stock was based upon book value. Book value of a subsidiary’s capital stock is calculated as of each preceding period end and represents the original purchase price of the subsidiary’s capital stock plus any income earned less any losses and any transfers of assets.

In respect of World-Wide Ventures Corp., Koppers Australia Holding Company Pty Ltd., Koppers Australia Pty Ltd., Koppers Redemption, Inc., Koppers Assurance, Inc. and Koppers Europe ApS, the Applicable Value of their common stock

18

Table of Contents

was based upon estimated market value. The Company has calculated the estimated market value of its subsidiaries’ capital stock by determining the earnings before interest, taxes, depreciation and amortization, or EBITDA, of each subsidiary for the twelve months ended December 31, 2004, and multiplying this EBITDA by a multiple used by the Company for purposes of valuing the common stock of its parent, KI Holdings Inc. KI Holdings Inc. retains an independent appraisal firm for purposes of calculating the market value of its common stock annually on a going concern basis, as provided for in the Company’s stockholders’ agreement, and in connection with determining equity-based compensation, and the Company has used the midpoint of the range used by such firm, based on the fact that the value of KI Holdings Inc. shares are based upon the performance of its wholly owned subsidiary, Koppers Inc. The Company determined that using this multiple is a reasonable and appropriate means for determining fair value of its subsidiaries’ capital stock.

As described above, the Company has used EBITDA of each of its subsidiaries solely for purposes of determining the estimated market value of the capital stock to determine whether that capital stock is included in the collateral. EBITDA is not a recognized financial measure under U.S. GAAP and does not purport to be an alternative to operating income as an indicator of operating performance or to cash flows from operating activities as a measure of liquidity. Additionally, EBITDA has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of the Company’s consolidated results as reported under U.S. GAAP. Because not all companies use identical calculations, the presentation of EBITDA also may not be comparable to other similarly titled measures of other companies. An evaluation should be made of the adjustments and the reasons the Company considers them appropriate for analysis for determining estimated market value of the capital stock of the Company’s subsidiaries.

A change in the Applicable Value of the capital stock of any of the Company’s subsidiaries could result in a subsidiary’s capital stock that was previously excluded from collateral becoming part of the collateral or a subsidiary’s capital stock that was previously included in collateral being excluded. The following table reflects the amount by which the Applicable Value of each subsidiary’s capital stock as of December 31, 2004 would have to increase in order for a portion of that subsidiary’s capital stock to no longer constitute collateral:

Legal Matters

The Company is involved in litigation and various proceedings relating to antitrust matters, environmental laws and toxic tort matters.

Government Investigations

On December 4, 2002 European Commission (“EC”) representatives visited the offices of the Company’s subsidiaries located in Nyborg, Denmark and Scunthorpe, England and obtained documents pursuant to legal process as part of an investigation of industry competitive practices concerning pitch, creosote and naphthalene. The United States Department of Justice (“DOJ”) also served a subpoena for similar documents at the Company’s headquarters in Pittsburgh, Pennsylvania. Koppers also contacted and coordinated with the Canadian Competition Bureau (“CCB”). Koppers has cooperated with the EC, DOJ and CCB in their respective investigations. In 2004, the DOJ returned the

19

Table of Contents

documents which the Company had produced. The return of such documents indicates that the DOJ’s investigation has been terminated. The Company has had no recent communications with the CCB. As a result of the Company’s cooperation, (i) in February 2003, the EC granted the Company’s request for exemption from penalties for any infringement the EC may have found as a result of its investigation concerning pitch; (ii) in April 2003, DOJ granted the Company’s request for exemption from prosecution for any infringement DOJ may have found as a result of imports of pitch, creosote and naphthalene, or the purchase for export of coal tar used to produce these products; and (iii) in April 2003, the CCB granted the Company a provisional guarantee of immunity from fines under the Canadian Competition Act with respect to the supply and sale of tar pitch, naphthalene, creosote oil and carbon black feedstock prior to 2001. These grants of immunity by the EC, DOJ and CCB apply to any government fine or penalty related to each country’s investigation of industry competitive practices. The Company’s failure to comply with the applicable conditions that were attached to these grants of immunity, could have subjected Koppers to fines to the extent that the investigations continued. Such fines, if assessed against the Company, could have had a material adverse effect on its business, financial condition, cash flows and results of operations. For example, the EC has the authority to assess fines in an amount up to 10% of a company’s worldwide sales. The DOJ and CCB also have the authority to assess significant fines.

In January 2005, the EC advised the Company that it had closed its investigation without prejudice to its right to re-open such investigation if new facts come to light.

The New Zealand Commerce Commission (the “NZCC”) is conducting an investigation related to the competitive practices of Koppers Arch New Zealand. Koppers Arch New Zealand is seeking to cooperate with the NZCC. The NZCC can bring court proceedings seeking penalties against companies that have violated New Zealand’s competition laws. However, penalties are assessed by the court. For example, the NZCC can seek fines for each alleged contravention of the competition laws equal to the higher of (i) $NZ10,000,000, (ii) three times the commercial gain from the contravention or (iii) 10% of the turnover of Koppers Arch New Zealand and all interconnected companies. Although it is likely that penalties will be assessed against Koppers Arch New Zealand as a result of the investigation, the Company does not currently have enough information to determine the amount of any such penalties. Such penalties, if assessed against Koppers Arch New Zealand, could have a material adverse effect on its business, financial condition, cash flows and results of operations. Except as set forth above, the Company is not currently aware of any other claims (civil or governmental) related to competitive practices in New Zealand. Such other claims, if filed against Koppers Arch New Zealand and resolved unfavorably, could have a material adverse effect on its business, financial condition, cash flows and results of operations.

Koppers Arch Australia has also made an application for leniency under the Australian Competition and Consumer Commission’s (the “ACCC”) policy for cartel conduct. The ACCC has granted immunity to Koppers Arch Australia, subject to the fulfillment of certain conditions, such as, but not limited to, continued cooperation. If the conditions are not fulfilled, Koppers Arch Australia may be penalized for any violations of the competition laws of Australia. Such penalties, if assessed against Koppers Arch Australia, could have a material adverse effect on its business, financial condition, cash flows and results of operations. Except as set forth above, the Company is not currently aware of any other claims (civil or governmental) related to competitive practices in Australia. Such other claims, if filed against Koppers Arch Australia and resolved unfavorably, could have a material adverse effect on its business, financial condition, cash flows and results of operations.

Koppers Arch New Zealand and Koppers Arch Australia are majority-owned subsidiaries of Koppers Arch Investments Pty Ltd, which is an Australian joint venture owned 51% by World-Wide Ventures Corporation (a subsidiary of the Company) and 49% by Hickson Nederland BV. Koppers Arch New Zealand and Koppers Arch Australia manufacture and market wood preservative products throughout New Zealand and Australia, respectively.

Pacific Century. A subsidiary of Koppers Australia has been named as a defendant in a breach of contract and negligence lawsuit filed by Pacific Century in Queensland, Australia related to the sale of approximately 127,000 vineyard trellis posts. The Complaint claims that certain posts were defective in that they either had decay, excessive bark or were less than the minimum specified size. In addition, plaintiff alleges violations of the Australian Timber Utilization and Marketing Act. Plaintiff is seeking damages in the amount of AU$6.6 million (approximately US$5.1 million) for, among other things, the costs of removing and replacing such trellis posts. Plaintiff has also filed a lawsuit against the constructor of the vineyard trellises, which lawsuit has been consolidated with its claim against the Company. Discovery in the case is ongoing and there can be no assurance that an unfavorable resolution of this matter will not have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

Product Liability Cases. The Company, along with other defendants, has been named as a defendant in eleven cases in Pennsylvania and four cases in Texas in which the plaintiffs claim they suffered a variety of illnesses (including cancer) as a result of exposure to one or more of the defendants’ products, including coal, coke and coal tar pitch. The cases are in the early stages of discovery, and therefore no determination can currently be made as to the likelihood or extent of any liability to Koppers. Although the Company intends to vigorously defend these cases, there can be no

20

Table of Contents

assurance that an unfavorable resolution of these matters will not have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

Grenada. Koppers, together with various co-defendants, has been named as a defendant in four toxic tort lawsuits in various state courts in Mississippi and in two toxic tort lawsuits in federal court in Mississippi arising from the operations of the Company’s wood treating plant in Grenada, Mississippi (“Grenada”). See “Environmental and Other Liabilities Retained or Assumed by Others”.

Other Financial Matters

Dividend Payments and Stock Redemption. In July 2004 the Company declared and paid a dividend totaling $8.4 million ($2.86 per share to common and preferred). The Company also paid a $25 million dividend ($8.00 per share to common and preferred) in January 2004 which had been declared in December 2003. Additionally, pursuant to a redemption offer the Company repurchased approximately 45,000 shares of common stock in April 2004 for a total of approximately $0.7 million.

Stock Purchases by Directors/Restricted Stock Grants to Senior Management. In August 2004 three members of the Company’s Board of Directors each purchased 5,000 shares of Koppers common stock at the current fair value. Additionally, in August 2004 Koppers granted 135,000 restricted stock units to certain officers, of which 20% vested August 31, 2004. The remaining units will vest annually at a rate of 20% per year. The Company recorded $0.5 million of compensation expense for the vesting of restricted stock grants during 2004.

Pension Funding. The Company contributed approximately $14.7 million to its defined benefit pension plans in 2004. The estimates of the Company’s U.S. defined benefit pension plan contributions reflect the provisions of the Pension Funding Equity Act of 2004, which was enacted in April 2004.

Restructuring Reserves. During 2003 the Company incurred restructuring and impairment charges of $8.5 million, of which $0.7 were cash charges for severance and related charges. At December 31, 2004 all of the cash charges had been paid and there were no remaining reserves.

Consolidation of Koppers China. In 1999 the Company entered into a joint venture agreement with TISCO to rehabilitate and operate a tar distillation facility in China. Koppers China is 60% owned by Koppers and began production of coal tar products in 2001. Contributions of cash, engineering services and acquisition costs for the joint venture total $10.5 million as of December 31, 2004. In June 2001, the Company entered into an agreement with TISCO whereby TISCO assumed control of Koppers China through December 31, 2003. The Company chose to delay development of the carbon pitch export market due to the restructuring of the North American aluminum smelting capacity. In the interim, TISCO assumed responsibility for the joint venture to develop the domestic Chinese market. During this period, TISCO bore all responsibility for the operations and management of the facility, as well as the net income or loss, except for the Company’s pro rata share of depreciation, amortization and income taxes of the joint venture. Accordingly, the Company changed its method of accounting from consolidation to the equity method effective June 2001 to reflect this change in its ability to control Koppers China.

On January 1, 2004, the Company resumed control of Koppers China, which resulted in the consolidation of Koppers China in its financial statements beginning in the first quarter of 2004. For the year ended December 31, 2004 sales and net income for Koppers China were $25.5 million and $2.7 million, respectively. The Company anticipates that the profitability of Koppers China will be negatively impacted by the slowing of the Chinese economy and lower selling prices for certain products in the near term.

Interest Rate Swap. In January 2004 the Company entered into an interest rate swap agreement for $50 million of the Senior Secured Notes in order to protect a portion of the debt against changes in fair value due to changes in the benchmark interest rate. The agreement is designed to receive fixed 9.875% and pay floating six-month LIBOR rates plus a spread of 5.395% with semiannual settlements through October 2013. Changes in the fair value of the interest rate swap are expected to offset changes in the fair value of the Senior Secured Notes. The impact on the year ended December 31, 2004 was to lower interest expense by approximately $1.3 million. The fair value of the swap agreement at December 31, 2004 was a liability of $0.9 million.

Stock Redemptions. For the year ended December 31, 2004, stock redemptions for terminated management investors, including retirees, totaled $1.3 million. On February 27, 2004 the Stockholders’ Agreement was amended to make the redemption of common stock from the Management Investors at the Company’s option after the effective date of the amendment. See “Certain Relationships and Related Party Transactions—Stockholders’ Agreement.”

Impact of Deferred Taxes. Based on the Company’s earnings history, along with the implementation of various tax planning strategies, the Company believes the deferred tax assets on its consolidated balance sheet at December 31, 2004 are realizable.

Foreign Operations and Foreign Currency Transactions. The Company is subject to foreign currency translation fluctuations due to its foreign operations. Exchange rate fluctuations for fiscal years 2004, 2003 and 2002 resulted in increases to comprehensive income of $5.6 million, $22.6 million, and $9.7 million, respectively. Koppers economically hedges certain firm commitments denominated in foreign currencies for periods up to twelve months, depending on the anticipated settlement dates of the related transactions. Forward exchange contracts are utilized to hedge these transactions, and all such contracts are marked to market with the recognition of a gain or loss at each reporting period. Therefore, at December 31, 2004 and 2003 there were no deferred gains or losses on hedging of foreign currencies. The fair value of derivatives at December 31, 2004 and 2003 was $0.1 million and $0.3 million, respectively, and is included in Other Current Assets and Other Current Liabilities. For the years ended December 31, 2004, 2003 and 2002, $0.0 million, $0.2 million and $0.0 million, respectively, of losses on forward exchange contracts are included in cost of sales. Realized foreign exchange gains for the years ended December 31, 2004, 2003 and 2002 amounted to $0.4 million, $0.3 million and $0.1 million, respectively.

Seasonality; Effects of Weather. The Company’s quarterly operating results fluctuate due to a variety of factors that are outside its control, including inclement weather conditions, which in the past have affected operating results. Operations at several facilities have been halted for short periods of time during the winter months. Moreover, demand for some of the Company’s products declines during periods of inclement weather. As a result of the foregoing, the Company anticipates that it may experience material fluctuations in quarterly operating results.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires management to use judgment in making estimates and assumptions that affect the reported amounts of revenues and expenses, assets and liabilities, and the disclosure of contingent liabilities. The following accounting policies are based on, among other things, judgments and assumptions made by management that include inherent risks and uncertainties. The Company’s estimates are based on the relevant information available at the end of each period.

Long-Lived Assets. The Company’s management periodically evaluates the net realizable value of long-lived assets, including property, plant and equipment, based on a number of factors including operating results, projected future cash flows and business plans. The Company records long-lived assets at the lower of cost or fair value, with fair value based on assumptions concerning the amount and timing of estimated future cash flows. Since judgment is involved in determining the fair value of fixed assets, there is a risk that the carrying value of the Company’s long-lived assets may be overstated.

Goodwill. Effective January 1, 2002, Koppers adopted SFAS No. 142, Goodwill and Other Intangible Assets, under which goodwill is no longer amortized but is assessed for impairment at least on an annual basis. In making this assessment, management relies on various factors, including operating results, estimated future cash flows, and business plans. There are inherent uncertainties related to these factors and in management’s judgment in applying them to the analysis of goodwill impairment. Since management’s judgment is involved in performing goodwill impairment analyses, there is risk that the carrying value of goodwill is overstated.

Goodwill valuations are performed using an average of actual and projected operating results of the relevant reporting units. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairments in future periods. Additionally, disruptions to the Company’s business such as prolonged recessionary periods or unexpected significant declines in operating results of the relevant reporting units could result in charges for goodwill and other asset impairments in future periods.

Revenue Recognition. The Company recognizes revenue from product sales at the time of shipment or when title passes to the customer. The Company recognizes revenue related to the procurement of certain untreated railroad crossties upon transfer of title, which occurs upon delivery to the Company’s plant and acceptance by the customer. Service revenue, consisting primarily of wood treating services, is recognized at the time the service is provided.

Inventories. In the United States, Carbon Materials & Chemicals (excluding furnace coke) and Railroad & Utility Products inventories are valued at the lower of cost, utilizing the last-in, first-out basis, or market. Inventories outside the United States are valued at the lower of cost, utilizing the first in, first-out basis, or market. Market represents replacement

23

Table of Contents

cost for raw materials and net realizable value for work in process and finished goods. Last-in, first-out inventories constituted approximately 59% and 55% of the first-in, first-out inventory value at December 31, 2004 and 2003, respectively.

Accrued Insurance. The Company is insured for property, casualty and workers’ compensation insurance up to various stop loss amounts after meeting required retention levels. Losses are accrued based upon estimates of the liability for the related retentions for claims incurred using certain actuarial assumptions followed in the insurance industry and based on the Company’s experience. In the event the Company incurs a significant number of losses beyond the coverage retention limits, additional expense beyond the actuarial projections would be required.

Pension and Postretirement Benefits. Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided far into the future and allocating that cost over the time period each employee works. This calculation requires extensive use of assumptions regarding inflation, investment returns, mortality, medical costs, employee turnover and discount rates. In determining the expected return on plan assets assumptions, the Company evaluates long-term actual return information, the mix of investments that comprise plan assets and estimates of future investment returns. In selecting rates for current and long-term health care assumptions, the Company takes into consideration a number of factors including its actual health care cost increases, the design of the Company’s benefit programs, the characteristics of its active and retiree populations and expectations of inflation rates. Since these items require management’s judgment, the related liabilities currently recorded by the Company could be lower or higher than amounts ultimately required to be paid.

Accounts Receivable. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. In circumstances where Koppers becomes aware of a specific customer’s inability to meet its financial obligations, a specific reserve for bad debts is recorded against amounts due. If the financial conditions of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Environmental Liabilities. The Company is subject to federal, state, local and foreign laws and regulations and potential liabilities relating to the protection of the environment and human health and safety, including, among other things, the cleanup of contaminated sites, the treatment, storage and disposal of wastes, the discharge of effluent into waterways, the emission of substances into the air and various health and safety matters. Koppers expects to incur substantial costs for ongoing compliance with such laws and regulations. The Company may also face governmental or third-party claims, or otherwise incur costs, relating to cleanup of, or for injuries resulting from, contamination at sites associated with past and present operations. The Company accrues for environmental liabilities when a determination can be made that they are probable and reasonably estimable. Total environmental reserves at December 31, 2004 and 2003 were approximately $4.7 million and $7.5 million, respectively, which include provisions primarily for fines and soil remediation.

Legal Matters. The Company records liabilities related to legal matters when an adverse outcome is probable and reasonably estimable. To the extent the Company anticipates favorable outcomes to these matters which ultimately result in adverse outcomes, Koppers could incur material adverse impacts on earnings and cash flows. Since such matters require significant judgments on the part of management, the recorded liabilities could be lower than what is ultimately required.

Asset Retirement Obligations. The Company measures asset retirement obligations based upon the applicable accounting guidance, using certain assumptions including estimates regarding the recovery of residues in storage tanks. In the event that operational or regulatory issues vary from management’s estimates, the Company could incur additional significant charges to income and increases in cash expenditures related to the disposal of those residues.

Deferred Tax Assets. At December 31, 2004, the Company’s balance sheet includes $59.6 million of deferred tax assets. The Company has determined that no reserve is required for these deferred tax assets, based on future earnings projections. To the extent that Koppers encounters unexpected difficulties in market conditions, adverse changes in regulations affecting its businesses and operations, adverse outcomes in legal and environmental matters, or any other unfavorable conditions, the projections for future taxable income may be overstated and Koppers may be required to record a valuation allowance related to these deferred tax assets which could have a material adverse effect on income in the future.

Recently Issued Accounting Guidance

In December 2004, the FASB issued SFAS No. 123 (Revised 2004), Share-Based Payments (“SFAS 123R”). SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized in

24

Table of Contents

the income statement based on their fair values. The Company is required to adopt the new standard in the first interim period beginning after June 15, 2005. The Company has not yet determined the impact, if any, of the adoption of SFAS 123R on its financial statements.

In December 2004, the FASB issued SFAS No. 153, Exchanges of Nonmonetary Assets, an amendment of APB Opinion 29 (“SFAS 153”). SFAS 153 requires that exchanges of nonmonetary assets be measured based on the fair values of the assets exchanged, and eliminates the exception to this principle under APB Opinion 29 for exchanges of similar productive assets. The Company is required to adopt the new standard in the first interim period beginning after June 15, 2005. The Company does not expect the adoption of SFAS 153 to have a material effect on its financial statements.

In December 2004, the FASB issued SFAS No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4 (“SFAS 151”). SFAS 151 clarifies that abnormal amounts of idle facility expense, freight, handling costs, and wasted materials should be recognized as current-period charges and requires the allocation of fixed production overheads to inventory based on the normal capacity of the production facilities. The Company is required to adopt the new standard in the fiscal year beginning after June 15, 2005. The Company has not yet determined the impact, if any, of the adoption of SFAS 151 on its financial statements.

American Jobs Creation Act of 2004. In October 2004, the American Jobs Creation Act of 2004 (the “AJCA”) was signed into law. The AJCA allows companies to repatriate earnings from foreign subsidiaries at a reduced U.S. tax rate. The FASB issued FASB Staff Position 109-1 to provide guidance on the application of SFAS No. 109, Accounting for Income Taxes, and FASB Staff Position 109-2 to provide accounting and disclosure guidance for the repatriation provision. The Company is evaluating the consequences of repatriating up to $3 million with a related range of income tax effects that cannot be reasonably estimated as of the time of issuance of these financial statements. The Company expects to complete its review by December 31, 2005, and will recognize the income tax effect, if any, in the period when a decision whether to repatriate is made.

In May 2004, the FASB issued Staff Position No. 106-2, Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (“FSP 106-2”). This Act was signed into law by the President on December 8, 2003 and introduces a prescription drug benefit plan under Medicare Part D as well as a federal subsidy to sponsors of retiree health benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. FSP 106-2 provides guidance on how companies should account for the impact of the Act on their postretirement health care plans. To encourage employers to retain or provide postretirement drug benefits, beginning in 2006 the federal government will provide non-taxable subsidy payments to employers that sponsor prescription drug benefits to retirees that are actuarially equivalent to the Medicare benefit. FSP 106-2 is effective for interim or annual financial statements beginning after June 15, 2004. The Company has determined that the benefits provided under its plans are not actuarially equivalent to Medicare Part D. Therefore, the Act has been determined to have no impact on the net periodic postretirement benefit cost included in the financial statements.

In December 2003, the FASB issued SFAS No. 132 (revised 2003), Employers’ Disclosures About Pensions and Other Postretirement Benefits, an amendment of FASB Statements No. 87, 88 and 106, and a revision of FASB Statement No. 132. This statement requires additional disclosure about the assets, obligations, cash flow and net periodic benefit cost of defined benefit pension plans and other postretirement benefit plans. This statement also requires interim disclosure of the net periodic benefit cost and actual or expected employer contributions. The standard is effective for fiscal years ending after December 15, 2003 and interim periods beginning after December 15, 2003. The Company has adopted SFAS No. 132 by adding the required disclosures.

In May 2003, the Financial Accounting Standards Board issued Statement No. 150, Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity, effective for the fiscal period beginning after December 15, 2003. Statement No. 150 establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. To the extent that the Company is required to purchase shares of common stock, the adoption of Statement No. 150 required the Company to classify common stock subject to redemption as a liability as of January 1, 2004. Prospectively, changes in the liability with the exception of redemptions will be included in pre-tax income.

Prior to February 27, 2004 the Company’s stockholders’ agreement required the Company to redeem shares of common stock owned by officers, directors, and the Company’s current and former employees upon a Management Investor’s ceasing for any reason to be employed by the Company. On February 27, 2004 the stockholders’ agreement was amended to make the redemption of common stock from such Management Investors at the Company’s option.

Table of Contents

The initial adoption of Statement No. 150 resulted in the recognition of a liability in the amount of $13.2 million for shares with a mandatory redemption requirement. At December 31, 2004 after giving effect to the amendment to the stockholders’ agreement as noted above, the remaining liability was $0.8 million based on prior commitments to redeem shares. Due to the amendment, $11.2 million was reclassified to capital in excess of par value to reflect the elimination of the mandatory redemption requirement.

Effective January 1, 2003, the Company changed its method of accounting for asset retirement obligations in accordance with FASB Statement No. 143, Accounting for Asset Retirement Obligations. Previously, the Company had not been recognizing amounts related to asset retirement obligations. Under the new accounting method, Koppers now recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of a fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.

The cumulative effect of the change on prior years resulted in a charge to income of $18.1 million, net of income taxes of $11.7 million.

In January 2003, the Financial Accounting Standards Board issued Interpretation No. 46, Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51 (“FIN No. 46”). FIN No. 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. In December 2003, FASB issued a revision to FIN No. 46; for the Company, the revised provisions of FIN No. 46 must be applied for the first interim or annual period beginning after December 15, 2004. The Company does not expect that the adoption of FIN No. 46 will have a material impact on its financial position, cash flows or results of operations.

In April 2002, the Financial Accounting Standards Board issued Statement No. 145, Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections, effective for fiscal years beginning after June 15, 2002. For most companies, Statement No. 145 will require gains and losses on extinguishments of debt to be classified as income or loss from continuing operations rather than as extraordinary items as previously required under Statement No. 4. Extraordinary treatment will be required for certain extinguishments as provided in APB Opinion No. 30. Statement No. 145 also amends Statement No. 13 to require that certain modifications to capital leases be treated as a sale-leaseback and modifies the accounting for subleases when the original lessee remains a secondary obligor (or guarantor). In addition, the FASB rescinded Statement No. 44, which addressed the accounting for intangible assets of motor carriers and made numerous technical corrections. The Company’s adoption of Statement No. 145 resulted in charges of $12.2 million during 2003 to income from continuing operations for costs related to extinguishment of debt rather than as an extraordinary item.

Environmental and Other Liabilities Retained or Assumed by Others

The Company has agreements with former owners of certain of the Company’s operating locations under which the former owners retained or assumed and agreed to indemnify Koppers against certain environmental and other liabilities. The most significant of these agreements was entered into at the Company’s formation on December 28, 1988 (the “Acquisition”). Under the related asset purchase agreement between the Company and Beazer East, subject to certain limitations, Beazer East retained the responsibility for and agreed to indemnify Koppers against certain liabilities, damages, losses and costs, including, with certain limited exceptions, liabilities under and costs to comply with environmental laws to the extent attributable to acts or omissions occurring prior to the Acquisition (the “Indemnity”). Beazer Limited unconditionally guaranteed Beazer East’s performance of the Indemnity pursuant to a guarantee (the “Guarantee”). Beazer Limited became a wholly owned indirect subsidiary of Hanson PLC on December 4, 1991. In 1998, Hanson PLC purchased an insurance policy under which the funding and risk of certain environmental and other liabilities relating to the former Koppers Company, Inc. operations of Beazer East (which includes locations purchased from Beazer East by us) are underwritten by Centre Solutions (a member of the Zurich Group) and Swiss Re.

The Indemnity provides different mechanisms, subject to certain limitations, by which Beazer East is obligated to indemnify Koppers with regard to certain environmental and other liabilities and imposes certain conditions on the Company before receiving such indemnification, including certain limitations regarding the time period as to which claims for indemnification can be brought. In July 2004, the Company entered into an agreement with Beazer East to amend the December 29, 1988 asset purchase agreement to provide, among other things, for the continued tender of pre-closing environmental liabilities to Beazer East under the Indemnity through July 2019. As consideration for the agreement, the Company will pay Beazer East four installments over three years totaling $7 million and share toxic tort litigation costs arising from any sites acquired from Beazer East. The first payment of $2 million was made in July 2004.

Table of Contents

Contamination has been identified at most of the Company’s manufacturing and other sites. Three sites owned and operated by Koppers in the United States, as well as one former site, are listed on the National Priorities List promulgated under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”). The sites include the Company’s Gainesville, Florida wood treating facility; the Company’s Galesburg, Illinois wood treating facility; the Company’s Florence, South Carolina wood treating facility; and the Company’s former Feather River, California wood treating facility. Currently, at the properties acquired from Beazer East (which include all of the National Priorities List sites and all but one of the Resource Conservation and Recovery Act (“RCRA”)-permitted sites), substantially all investigative, cleanup and closure activities are being conducted and paid for by Beazer East pursuant to the terms of the Indemnity. In addition, other of the Company’s sites are or have been operated under RCRA and various other environmental permits, and remedial and closure activities are being conducted thereat.

To date, the parties that retained, assumed or agreed to indemnify Koppers against the liabilities referred to above have performed their obligations in all material respects. The Company believes that for the last three years amounts paid by Beazer East as a result of its environmental remediation obligations under the Indemnity have averaged in total approximately $11.6 million per year. If for any reason (including disputed coverage or financial incapability) one or more of such parties fail to perform their obligations and Koppers is held liable for or otherwise required to pay all or part of such liabilities without reimbursement, the imposition of such liabilities on the Company could have a material adverse effect on its business, financial condition, cash flows and results of operations. In addition, if Koppers were required to record a liability with respect to all or a portion of such matters on its balance sheet, the amount of the Company’s total liabilities could exceed the book value of its assets by an additional amount that could be significant.

Also, contamination has been detected at certain of the Company’s Australian facilities. These sites include the tar distillation facility in Mayfield, NSW, Australia and the wood protection chemicals facility in Trentham, Victoria, Australia, which has been listed on the Victorian register of contaminated sites. The Company’s reserves include $1 million for the estimated remediation costs at these sites.

Grenada. Koppers, together with various co-defendants (including Beazer East), has been named as a defendant in four toxic tort lawsuits in various state courts in Mississippi and in two toxic tort lawsuits in federal court in Mississippi arising from the operation of Grenada. The Complaints allege that plaintiffs were exposed to harmful levels of various toxic chemicals, including creosote, pentachlorophenol and dioxin, as a result of soil, surface water and groundwater contamination and air emissions from the Grenada facility and, in the state court cases, from an adjacent manufacturing facility operated by Heatcraft, Inc. In the state court actions, which include a total of approximately 115 plaintiffs, each plaintiff seeks compensatory damages from the defendants of at least $5 million for each of seven counts and punitive damages of at least $10 million for each of three counts. In the federal case action referred to as the Beck case, there are a total of approximately 110 plaintiffs. Each plaintiff in the Beck case seeks compensatory damages from the defendants in an unspecified amount and punitive damages of $20 million for each of four counts. In the federal case action referred to as the Ellis case, there are approximately 1,130 plaintiffs. Each plaintiff in the Ellis case seeks compensatory damages from the defendants of at least $5 million for each of seven counts and punitive damages of at least $10 million for each of three counts. Based on its experience in defending previous toxic tort cases (including the Company’s victory in similar litigation involving Green Spring and its recent dismissal without prejudice from similar litigation involving Somerville, as noted below), the Company does not believe that the damages sought by the plaintiffs in the state court and federal court actions are supported by the facts of the cases. The Company is seeking to transfer venue of the state court cases to Grenada County, Mississippi. The venue issue is currently on appeal to the Mississippi Supreme Court. During the pendency of the appeal, discovery in the state court cases has been stayed. Discovery in the federal court cases has also been stayed. However, discovery with respect to 12 plaintiffs is proceeding in the Beck federal case. The trials of the 12 Beck plaintiffs are currently scheduled to commence in October 2005. Although the Company intends to vigorously defend these cases, there can be no assurance that an unfavorable resolution of this matter will not have a material adverse effect on its business, financial condition, cash flows and results of operations.

Somerville. Koppers, along with Burlington Northern and Santa Fe Rail Way Company and Solvents and Chemicals, Inc., was named in a total of 11 toxic tort lawsuits by a total of approximately 30 plaintiffs that were filed in various state courts in Texas by individuals claiming to be residents of Somerville, Texas. The Complaints alleged that plaintiffs suffered personal injuries resulting from exposure to chemicals used at Somerville. The plaintiffs sought actual damages and punitive damages in an unspecified amount from the defendants. Koppers has been voluntarily dismissed without prejudice by the plaintiffs from all of the Somerville lawsuits. The lawsuits are proceeding against the remaining defendants.

Other Environmental Matters

In October 1996, Koppers received a Clean Water Act information request from the U.S. Environmental Protection Agency (“EPA”). This information request asked for comprehensive information on discharge permits, applications for discharge permits, discharge monitoring reports and the analytical data in support of the reports and applications. EPA subsequently alleged that the Company violated various provisions of the Clean Water Act. Koppers subsequently agreed, among other things, to a $2.9 million settlement, payable in three annual installments. The first two payments, totaling $1 million each, were made in April 2004 and 2003, respectively.

Additionally, during an investigation the Company initiated at its Woodward Coke facility prior to its closure in January 1998, it was discovered that certain environmental records and reports related to the discharge of treated process water contained incomplete and inaccurate information. Corrected reports were submitted to the State of Alabama and EPA, which resulted in a Complaint against Koppers by EPA alleging certain civil and criminal violations of applicable environmental laws. The Company subsequently entered into a plea agreement and a related compliance agreement addressing this matter, which together provide, among other things, for the payment by Koppers of a $2.1 million fine payable to the government and $0.9 million in restitution payable to the Black Warrior-Cahaba Rivers Land Trust in three equal annual installments beginning in December 2002. The Company’s plea was entered in August 2002 and the sentencing occurred in December 2002. At the sentencing, the court, among other things, approved the terms of the plea agreement previously negotiated between Koppers and EPA. The first two payments, totaling $1.0 million each, were made in December 2003 and 2002, respectively. The final payment of $1.0 million was completed in January 2005. A failure on the Company’s part to comply with the terms of the compliance agreement, plea agreement and probation could lead to significant additional costs and sanctions, including the potential for its suspension or debarment from governmental contracts.

Other Business Matters

There are currently no known viable substitutes for carbon pitch in the production of carbon anodes. However, in 2000, the Company’s largest carbon pitch customer announced that it was actively pursuing alternative anode technology that would eliminate the need for carbon pitch as an anode binder. No commercial development of this technology has occurred since this announcement. Although management does not believe that this alternative technology will be developed and used widely within the next five years, the potential development and implementation of this new technology could seriously impair the Company’s ability to profitably market carbon pitch and related co-products. Approximately 75% of the Company’s carbon pitch is sold to the aluminum industry under long-term contracts typically ranging from three to four years.

Global restructuring in the electrode and aluminum markets has resulted in reduced volumes of carbon pitch in domestic markets. As a result, during 2003 the Company ceased production at its carbon materials facility in Woodward, Alabama and also determined that the Company’s port facility in Portland, Oregon was an impaired facility. Restructuring and impairment charges of $7.2 million and related charges of $4.9 million were recorded to pre-tax income in the fourth quarter of 2003 for the Carbon Materials and Chemicals segment.

Over the last several years, utility pole demand has dropped as utilities in the United States and Australia have reduced spending due to competitive pressures arising from excess capacity and deregulation. It is expected that excess capacity and deregulation will continue to negatively affect pole markets.

Like other global companies, Koppers is exposed to market risks relating to fluctuations in interest rates and foreign currency exchange rates. The objective of the Company’s financial risk management is to minimize the negative impact of interest rate and foreign exchange rate fluctuations on the Company’s earnings, cash flows and equity.

To manage the interest rate risks, the Company uses a combination of fixed and variable rate debt. This reduces the impact of short-term fluctuations in interest rates. The Company uses forward exchange contracts to hedge firm commitments up to twelve months. Forward exchange contracts are utilized to hedge these transactions, and all such contracts are marked to market with the recognition of a gain or loss at each reporting period.

As required by the Securities and Exchange Commission (“SEC”) rules, the following analyses present the sensitivity of the market value, earnings and cash flows of the Company’s financial instruments and foreign operations to hypothetical changes in interest and exchange rates as if these changes occurred at December 31, 2004 and 2003. The range of changes chosen for these analyses reflects the Company’s view of changes which are reasonably possible over a one-year period. Market values are the present values of projected future cash flows based on the interest rate and exchange rate assumptions. These forward-looking statements are selective in nature and only address the potential

impacts from financial instruments and foreign operations. They do not include other potential effects that could impact the Company’s business as a result of these changes.

Interest Rate and Debt Sensitivity Analysis. The Company’s exposure to market risk for changes in interest rates relates primarily to the Company’s debt obligations. As described in Note 3 of the Company’s Notes to Consolidated Financial Statements, the Company has both fixed and variable rate debt to manage interest rate risk and to minimize borrowing costs. In January 2004, the Company also entered into an interest rate swap arrangement with respect to $50 million of the $320 million 9 ⁷/8% Senior Secured Notes due 2013. (See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”)

At December 31, 2004, Koppers had $273.8 million of fixed rate debt and $112.0 million of variable rate debt (after consideration of the swap arrangement described above). At December 31, 2003 Koppers had $323.8 million of fixed rate debt and $16.9 million of variable rate debt. The Company’s ratio of variable rate debt at December 31, 2004, including the $50 million interest rate swap referred to above, was approximately 29%, reflecting an increase in the ratio from 20% in the previous period. These ratios are low from a historical perspective, reflecting a change in strategy as a result of refinancing the Company’s debt structure during 2003 to take advantage of the favorable climate in the corporate bond markets and to provide a long-term debt structure to help facilitate the Company’s long-term cash requirements. For fixed rate debt, interest rate changes affect the fair market value but do not impact earnings or cash flows. For variable rate debt, interest rate changes generally do not affect the fair market value but do impact future earnings and cash flows, assuming other factors are held constant.

Holding other variables constant (such as debt levels and foreign exchange rates), a one percentage point decrease in interest rates at December 31, 2004 and 2003 would have increased the unrealized fair market value of the fixed rate debt by approximately $19.4 million for each period. The earnings and cash flows for the next year assuming a one percentage point increase in interest rates would decrease approximately $0.6 million, holding other variables constant.

Exchange Rate Sensitivity Analysis. The Company’s exchange rate exposures result primarily from the Company’s investment and ongoing operations in Australia, Denmark and the United Kingdom. Holding other variables constant, if there were a ten percent reduction in all relevant exchange rates, the effect on the Company’s earnings, based on actual earnings from foreign operations for the years ended December 31, 2004 and 2003, would be reductions of approximately $1.6 million and $1.5 million, respectively.

The financial statements and supplementary data required by Item 8 are included in this Annual Report on Form 10-K beginning on page 38 and are listed in Item 15 hereof.

None

Option Exercises and Fiscal Year-End Values

In November 2004, all of the Company’s outstanding stock and stock options were converted on a one-for-one basis for shares and options of the Company’s recently formed parent, KI Holdings Inc. As a result, at December 31, 2004 there were no remaining outstanding stock options for the Company. There were no Koppers Inc. options exercised by any Named Executive Officers during 2004, and no SARS were granted to any of the Named Executive Officers and none of the Named Executive Officers held any unexercised SARS at the end of the fiscal year.

Benefit Plans

Pension Plan. All the Company’s executive officers located in the U.S. are covered by the Retirement Plan of Koppers Inc. and Subsidiaries for Salaried Employees (the “Salaried Plan”). Prior to June 1, 2004, annual retirement benefits were computed at the rate of 1.2% of Terminal Salary (the “Normal Pension”) not in excess of $16,000, plus 1.6% of Terminal Salary in excess of $16,000, all multiplied by years of Credited Service (as defined below). Terminal Salary was determined based on the average annual salary (defined as salary plus 50% of any incentive payments) for the five highest consecutive years of the last ten years of credited service, or during all years of such credited service if less than five. Credited Service includes all accumulated service after January 1, 1989 as a salaried employee except for any period of layoff or leave of absence. In 1998, the Company amended the Salaried Plan to provide a minimum pension equal to 1.2% of Terminal Salary multiplied by years of Credited Service up to 35 years reduced by any pension benefit paid by the pension plan of the former Koppers Company, Inc., now known as Beazer East, Inc. (“Old Koppers” for the period prior to December 29, 1988) (the “Minimum Pension”). For purposes of the Minimum Pension calculations, Terminal Salary was determined based on the average annual salary (defined as salary plus 75% of any incentive payments) for the five highest consecutive years of the last ten years of Credited Service, or during all years of Credited Service if less than five. Prior to June 1, 2004, the annual retirement benefit for executive officers was computed based on the higher of the Normal Pension and the Minimum Pension.

The following table contains approximate retirement benefits for Credited Service before June 1, 2004 payable under the Salaried Plan, assuming retirement at age 65, payments made on the straight-life annuity basis and no election of a co-annuitant option.

Credited Service

Effective June 1, 2004 the Company further amended the Salaried Plan. For Credited Service as of May 31, 2004, benefits were frozen under the prior formulas. For Credited Service after May 31, 2004, annual retirement benefits are computed at the rate of 1.0% of Terminal Salary multiplied by years of Credited Service after May 31, 2004. Effective June 1, 2004 the Company also amended the definition of Terminal Salary to mean the average annual salary (defined as salary plus 100% of any incentive payments) for the five highest consecutive years of the last ten years of Credited Service or during all years of Credited Service if less than five.
