The accompanying notes are an integral part of these condensed consolidated financial statements.

The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States applicable to interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation of Koppers Holdings Inc.’s and its subsidiaries’ (“Koppers”, “Koppers Holdings” or the “Company”) financial position and interim results as of and for the periods presented have been included. All such adjustments are of a normal recurring nature unless disclosed otherwise. Because the Company’s business is seasonal, results for interim periods are not necessarily indicative of those that may be expected for a full year. The Condensed Consolidated Balance Sheet for December 31, 2005 has been summarized from the audited fiscal year 2005 balance sheet.

The financial information included herein should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in its 2005 Annual Report on Form 10-K.

In October 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard No. 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106 and 132(R) (“SFAS 158”). SFAS 158 requires a company to recognize in its balance sheet an asset for a defined benefit postretirement plan’s overfunded status or a liability for a plan’s underfunded status. SFAS 158 does not change the amount of net periodic benefit expense otherwise included in net income under existing accounting standards. SFAS 158 is effective for fiscal years beginning after December 15, 2006. The Company is currently evaluating the impact that will result from the adoption of SFAS 158.

In September 2006, the FASB issued SFAS 157, Fair Value Measurements. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact that will result from the adoption of SFAS 157.

In July 2006, the FASB issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109 (“FIN 48”). FIN 48 prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that a company has taken or expects to take on a tax return. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company is currently evaluating the impact that will result from the adoption of FIN 48.

In May 2005, the FASB issued SFAS 154, Accounting Changes and Error Corrections. SFAS 154 replaces APB Opinion No. 20, Accounting Changes, and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements, and changes the requirements for the accounting for and reporting of a change in accounting principle. SFAS 154 applies to all voluntary changes in accounting principle, and requires retrospective application to prior periods’ financial statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative

effect of the change. SFAS 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS 154 did not have a material effect on the Company’s financial statements.

In December 2004, the FASB issued SFAS No. 123 (Revised 2004), Share-Based Payments (“SFAS 123(R)”). SFAS 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. The Company was required to adopt the new standard in the fiscal year beginning after December 15, 2005. The adoption of SFAS 123(R) did not have a material effect on the Company’s 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 was required to adopt the new standard in the fiscal year beginning after June 15, 2005. The adoption of SFAS 151 did not have a material effect on the Company’s financial statements.

The Company completed an initial public offering (“IPO”) on February 6, 2006, resulting in the issuance of 8,700,000 additional common shares at a price of $14.00 per share, and the conversion of 2,288,481 shares of preferred stock into 9,107,926 shares of common stock. Of such converted shares, 2,800,000 were sold by the Company’s shareholders in connection with the IPO and the related over-allotment option. The Company received approximately $111.2 million of net proceeds (after $10.6 million of expenses) from the issuance and sale of 8,700,000 shares, which proceeds were used to redeem $101.7 million principal amount of the Senior Secured Notes due 2013 (the “Senior Secured Notes”) and pay a related call premium of $10.1 million. The Company wrote off $3.2 million of deferred financing costs related to the buyback of the notes and incurred $1.1 million of bond consent fees. The call premium, write-off of deferred financing costs, and consent fees were recorded as interest expense. The Company also incurred $3.0 million for the termination of the Saratoga Partners III, L.P. (“Saratoga”) advisory services contract, which was recorded in selling, general and administrative expense. A post-IPO dividend of $8.2 million, the consent fees and the Saratoga termination fee were financed through borrowings under the revolving credit agreement.

On July 27, 2006 the Company’s board of directors declared a quarterly dividend of $0.17 per common share which was paid on October 2, 2006 to holders of record as of September 1, 2006.

On November 2, 2006, the Company’s board of directors declared a quarterly dividend of $0.17 per common share, payable on January 2, 2007 to shareholders of record as of November 30, 2006.

in 2005, is expected to result in reduced costs and increased operating efficiencies for the Company since the majority of the sales and production will be transferred to two of the Company’s other existing wood treating facilities. The Company accrued $0.2 million of severance charges in 2006 related to the termination of approximately 20 employees. Previously, the Company incurred an asset impairment charge of $0.6 million related to this facility in the fourth quarter of 2005.

On April 28, 2006 the Company acquired certain assets of Reilly Industries, Inc.’s (“Reilly”) carbon materials business. The purchased assets consist primarily of inventories, customer sales contracts, raw material supply contracts, rail car leases and a non-compete agreement. The Company is integrating the additional tar distillation production at its existing facilities in the U.S. Results of operations for the three and nine months ended September 30, 2006, included the business acquired from Reilly from the date of acquisition. Net sales from the date of acquisition to September 30, 2006 totaled $36.1 million.

The aggregate purchase price was $45.1 million which was primarily funded by a $40.0 million term loan with an existing bank group, cash and a current payable to Reilly for working capital adjustments. The aggregate purchase price includes $0.1 million of transaction costs. The following table is a summary of the allocated purchase price to estimated fair values of the assets acquired and liabilities assumed at the date of acquisition. Independent appraisals were obtained to determine the fair value of the identifiable intangible assets subject to amortization. Refinements to the allocated purchase price are expected to be made as additional information becomes available.

Asset retirement obligations are associated with cleaning costs for leased and owned rail cars and the removal and disposal of residue from storage tanks located on leased property. The $25.8 million of goodwill was assigned to the Carbon Materials & Chemicals segment. The total amount of purchase price allocated to goodwill, customer contracts and the non-compete agreement is expected to be deductible for tax purposes over a 15-year period.

On June 22, 2006, the Company sold its specialty track products business and related assets located at the Company’s facility in Alorton, Illinois for cash of $1.9 million. This business was a component of the Railroad & Utility Products segment. The Company recorded a loss on disposal, before tax, of $1.6 million which is recorded as a component of cost of sales. Sales contributed by the business unit for the nine months ended September 30, 2006 and September 30, 2005 were $3.2 million and $5.8 million, respectively. Operating loss for the nine months ended September 30, 2006 and September 30, 2005 was ($0.5) million and ($0.2) million, respectively. Sales and operating profit for the three months ended September 30, 2005 were $2.0 million and $0.1 million, respectively.

Total comprehensive income for the three and nine months ended September 30, 2006 and 2005 is summarized in the table below:

The senior convertible preferred stock (“preferred stock”) had voting rights (except as noted below) and dividend rights equal to 3.9799 times the dividend rate on common stock, and had a liquidation preference equal to par value ($0.01 per share). The preferred stock was convertible into common stock at any time. The holders of the preferred stock voted as a separate series from all other classes of stock, and were entitled to elect a majority of the board of directors of the Company. In January 2006 the preferred stock was converted into shares of common stock on a 3.9799-for-one basis in connection with the Company’s initial public offering and no shares of preferred stock are currently outstanding.

Prior to the conversion of the senior convertible preferred stock into shares of common stock (see above), earnings per common share were based on the distributed and undistributed net income (loss) to common stockholders in accordance with Emerging Issues Task Force No. 03-06, Participating Securities and the Two-Class Method Under FASB Statement No. 128. In accordance with its terms, the senior convertible preferred stock did not participate in undistributed net losses. Accordingly, all undistributed net losses were allocated to the Company’s common shareholders for purposes of calculating earnings per share. Diluted earnings per common share assumed that any dilutive preferred shares outstanding at the beginning of the year were converted at those dates, with dividend

requirements and outstanding common shares adjusted accordingly. It also assumed that outstanding common shares were increased by shares issuable upon vesting of restricted stock and exercise of stock options for which fair value exceeds exercise price, and shares that could have been purchased by the Company with related proceeds. The senior convertible preferred stock and restricted stock was not included in the computation of diluted earnings per share for the three and nine months ended September 30, 2005 since it would have resulted in an antidilutive effect.

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

On August 31, 2006, the Company issued 107,457 common shares to certain employees, gross of 26,806 common shares withheld for statutory tax withholding, in accordance with the vesting schedule of its Restricted Stock Unit Plan. As of September 30, 2006, there are 214,915 non-vested restricted stock units which will vest in equal amounts in 2007 and 2008. Compensation expense related to the vesting of restricted stock units totaled $0.1 million and $0.3 million for the three and nine months ended September 30, 2006, respectively.

The following table sets forth certain sales and operating data, net of all intersegment transactions, for the Company’s segments for the periods indicated:

The following table sets forth certain tangible and intangible assets allocated to each of the Company’s segments for the periods indicated:

Income taxes as a percentage of pretax income is 34.5 percent and 46.6 percent for the nine months ended September 30, 2006 and 2005, respectively, The income tax provision for the first nine months of 2006 reflects an estimated effective tax rate, exclusive of discrete items, of 34.5 percent as compared to an estimated effective tax rate, exclusive of discrete items, of 40.9 percent for the first nine months of 2005. The effective tax rate for the first nine months of 2006 differs from the U.S. federal statutory rate of 35.0 percent due to the recognition of non-conventional fuel tax credits (-10.9 percent) offset by taxes on foreign earnings (+8.0 percent) and other permanent items (+2.4 percent). With respect to the first nine months of 2005, the effective tax rate differs from the federal statutory rate due to taxes on foreign earnings (+3.8 percent) and other permanent items (+2.1 percent). The first nine months of 2005 included a discrete tax item of $1.2 million related to a non-deductible penalty imposed by the New Zealand Commerce Commission (see Note 17).

The income tax provision for interim periods is based on an estimated annual effective tax rate, which requires management to make its best estimate of annual pretax income by domestic and foreign jurisdictions and other items that impact taxable income. During the year, management regularly updates estimates based on changes in various factors such as product prices, shipments, product mix, operating and administrative costs, mix of earnings by taxable jurisdiction, repatriation of foreign earnings, uncertain tax positions and the ability to claim tax credits such as the non-conventional fuel tax credit. To the extent that actual results vary from the estimates at the end of the third quarter, the actual tax provision recognized for 2006 could be materially different from the forecasted annual tax provision as of the end of the third quarter.

Net inventories as of September 30, 2006 and December 31, 2005 are summarized in the table below:

The change in the carrying amount of goodwill attributable to each business segment for the nine months ended September 30, 2006 was as follows:

The Company’s identifiable intangible assets with finite lives are being amortized over their estimated useful lives and are summarized below:

The customer contracts have estimated useful lives of 5 to 10 years and the non-compete agreements have estimated useful lives of 3 years. Total amortization expense related to these identifiable intangible assets was $0.7 million and $0.5 million for the three months ended September 30, 2006 and 2005, respectively. Total amortization expense was $1.9 million and $0.8 million for the nine months ended September 30, 2006 and 2005, respectively. As of September 30, 2006, estimated future amortization expense of identifiable intangible assets is $0.7 million for the remaining three months of 2006. Estimated amortization expense for the proceeding five years is summarized below:

The Company sponsors several pension plans that cover substantially all employees. Additionally, the Company provides postretirement health care benefits to a portion of its U.S. workforce. The following table provides the components of net periodic benefit cost for the pension plans for the three and nine months ended September 30, 2006 and 2005:

The following table provides the components of net periodic benefit cost for the other postretirement benefits for the three and nine months ended September 30, 2006 and 2005:

On November 2, 2006, the Company’s board of directors approved a freeze of the Company’s qualified and corresponding non-qualified defined benefit plans for salaried employees. Effective December 31, 2006, salaried employees will no longer accrue additional years of service or recognize future increases in compensation under the existing defined benefit plans for benefit purposes. In lieu of the reduction in benefits under the qualified defined benefit plan, the Company will provide, based on age and years of service, a uniform employer contribution of at least 3 percent and up to a maximum of 9 percent of salary to the salaried employee’s defined contribution plan. The Company will also continue to match contributions by salaried employees at an amount equal to 50 percent of the first 6 percent of compensation contributed by the employee.

The estimated net impact of these retirement plan changes is not expected to have a material impact on future benefit plan expense or future benefit plan funding. Pending final actuarial calculations on the impact of the plan freezes and other considerations regarding the structure of potential successor pension plans, the estimated curtailment loss to be recognized in the fourth quarter of 2006 could be as high as $1.7 million.

As disclosed in Note 3, the Company used proceeds from its initial public offering to redeem $101.7 million principal amount of the Senior Secured Notes in March 2006.

The Koppers Inc. credit agreement was amended in connection with the Company’s initial public offering in February 2006 and was subsequently amended in April 2006 in connection with the acquisition of certain assets of the carbon materials business of Reilly. The credit agreement, as amended, provides for a revolving credit facility of up to $125.0 million and term loans of $59.0 million. The loans are secured by a first priority lien on substantially all of Koppers Inc.’s assets, including the assets of certain significant subsidiaries. Revolving credit availability is calculated based on receivables and inventory as well as the attainment of certain financial ratios. The credit facility contains certain covenants that limit capital expenditures by Koppers Inc. and restrict its ability to incur additional indebtedness, create liens on its assets, enter into leases, pay dividends and make investments or acquisitions. In addition, such covenants give rise to events of default upon the failure by Koppers Inc. to meet certain financial ratios.

As of September 30, 2006, the Company had $49.9 million of unused revolving credit availability for working capital purposes after restrictions by various debt covenants and certain letter of credit commitments. As of September 30, 2006, $19.7 million of commitments were utilized by outstanding letters of credit. In addition, as of September 30, 2006, the Company had outstanding term loans of $55.0 million under the credit facility.

The Company accrues for product warranty liabilities based on historical loss experience and sales of extended warranties on certain products. The following table provides the activity in these reserves:

The Company and its subsidiaries are involved in litigation and various proceedings relating to environmental laws and regulations and antitrust, toxic tort, product liability and other matters. Certain of these matters are discussed below. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the consolidated financial statements.

Government Investigations. In April 2005, the New Zealand Commerce Commission (the “NZCC”), filed a Statement of Claim in the High Court of New Zealand against a number of corporate

and individual defendants, including Koppers Arch Wood Protection (NZ) Limited, (“KANZ”), Koppers Arch Investments Pty Limited, (“KAI”), Koppers Australia Pty Limited (“Koppers Australia”) and a number of other corporate and individual defendants. This followed an investigation by the NZCC into the competitive practices of the wood preservative industry in New Zealand. KANZ and Koppers Arch Australia are majority-owned subsidiaries of Koppers Arch Investments Pty Limited, which is an Australian joint venture owned 51% by World-Wide Ventures Corporation (an indirect subsidiary of the Company) and 49% by Hickson Nederland BV. KANZ and Koppers Arch Australia manufacture and market wood preservative products throughout New Zealand and Australia, respectively.

On February 23, 2006 the NZCC, KANZ, KAI and Koppers Australia executed a cooperation agreement (the “Cooperation Agreement”) which was subsequently approved by the New Zealand High Court on April 6, 2006. The Cooperation Agreement provides, among other things, that KANZ, KAI and Koppers Australia must cooperate with the NZCC until such time as the NZCC’s investigation and any related court proceedings have been concluded. It also provides that the NZCC will discontinue all proceedings against Koppers Australia and that the NZCC will assess penalties against KANZ and KAI for breaches of the New Zealand Commerce Act of 1986 (the “Act”). Total accruals in 2006 and 2005 for the penalties, costs and proposed settlements of other certain contingent liabilities totaled $2.8 million of which $2.4 was paid in the second quarter of 2006. Except as set forth above, no other claims (civil or governmental) related to competitive practices in New Zealand have been filed against the Company or its subsidiaries including KANZ and KAI. It is possible that customers and/or a competitor could file civil claims against KANZ and KAI. Such other claims, if filed and resolved unfavorably, could have a material adverse effect on the business, financial condition, cash flows and results of operations of the Company.

Koppers Arch Australia has 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. No civil claims related to competitive practices in Australia have been filed against the Company or its subsidiaries. Such civil claims, if filed and resolved unfavorably, could have a material adverse effect on the business, financial condition, cash flows and results of operations of the Company.

Pacific Century. In October 2002, Koppers Timber Preservation Pty Ltd, a subsidiary of Koppers Australia, was named as a defendant in a breach of contract and negligence lawsuit filed by Pacific Century Production Pty Ltd related to the sale of approximately 127,000 vineyard trellis posts. The complaint claimed that certain posts were defective. Plaintiff also filed a lawsuit and Koppers Australia filed a third party claim against the constructor of the vineyard trellises, which is still pending. Koppers Australia has settled with plaintiff and has withdrawn its third party claim against the constructor of the trellises, but Koppers Australia must reimburse the trellis constructor for certain court costs. A provision of approximately $0.9 million has been made for this matter, of which $0.4 million was paid in the second quarter of 2005.

Product Liability Cases. Koppers Inc., along with other defendants, is currently a defendant in lawsuits filed in Pennsylvania and Texas in which the plaintiffs claim they suffered a variety of illnesses (including cancer) as a result of exposure to coal tar pitch sold by the defendants. The first of these

cases was filed in April 2000 and the most recent was filed in April 2006. A number of plaintiffs in one of the cases have withdrawn their claims against Koppers Inc. and one of the cases (involving a single plaintiff) has been dismissed voluntarily. There are a total of 24 cases filed in state court in Pennsylvania and two cases filed in state court in Texas. There are currently 55 plaintiffs in these cases who are making claims against the Company. The complaints applicable to 37 of the plaintiffs allege that plaintiffs are entitled to recover compensatory and punitive damages in unspecified amounts in excess of the minimum jurisdictional limits of the applicable courts (in most cases $25,000). The complaints applicable to 18 of the plaintiffs allege that plaintiffs are entitled to recover compensatory damages in unspecified amounts in excess of the minimum jurisdictional limits of the applicable courts (in most cases $25,000). The complaints filed by two of the plaintiffs seek damages not to exceed $10.0 million. The other defendants vary from case to case and include companies such as Beazer East, Inc., USX Corporation, Honeywell, Inc., Reilly Industries, Inc., Dow Chemical Company, Rust-Oleum Corporation, UCAR Carbon Company, Inc., Exxon Mobil Corporation, Crompton Corporation, SGL Carbon Corporation, Alcoa, Inc., and PPG Architectural Finishes Inc. Discovery is proceeding in these cases. The Company has not provided a reserve for these lawsuits because, at this time, the Company cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. Although Koppers Inc. is vigorously defending these cases, an unfavorable resolution of these matters may have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

Koppers Inc. has also been served with complaints in 10 cases involving 22 plaintiffs who allege exposure to benzene and benzene containing products, including oils and solvents sold by Koppers Inc. Most of these cases also involve numerous other defendants in addition to Koppers Inc. The Company has not provided a reserve for these lawsuits because, at this time, the Company cannot reasonably determine the probability of loss, and the amount of loss, if any, cannot be reasonably estimated.

Somerville Cases. In June 2005, Koppers Inc. was served with a putative class action complaint in federal court in Austin, Texas against it and other defendants including the Burlington Northern Santa Fe Railway Company (the “BNSF”), Monsanto Company, Dow Chemical Company and Vulcan Materials Company. Plaintiffs claimed that several classes of past and present property owners and residents in the Somerville, Texas area suffered unspecified property damage and risk of personal injury as a result of exposure to various chemicals used at the Somerville, Texas wood treatment plant that is currently owned by Koppers Inc. On December 23, 2005, plaintiffs filed an amended complaint dropping their class action allegations and identifying 602 individual plaintiffs. The amended complaint seeks to recover compensatory and punitive damages in excess of the jurisdictional limits of the court for, among other things, bodily injuries, pain and mental anguish, emotional distress, medical monitoring, medical expenses, lost wages, loss of consortium and property devaluation. In October 2006, the court ordered each of the 602 individual plaintiffs to sever his or her claims and file a separate lawsuit within 30 days. Those who sever their claims and pay the filing fees may seek to transfer their claims to any court with original jurisdiction. The court also ordered that all claims not severed within 30 days be dismissed without prejudice.

In September 2006 and October 2006, the Company was served with two other cases involving similar allegations relating to the Somerville, Texas plant. These cases were filed in state court in Burleson County, Texas. The BNSF has also been named as a defendant in both cases. The September 2006 case presently has 22 plaintiffs (three of whom have claims only against the BNSF) and the October 2006 case has two plaintiffs who seek to recover special, exemplary and actual damages.

All of these cases are in the pleadings stage and the Company has not yet been required to respond to discovery. The Company has not provided a reserve for these matters because, at this

time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. Although Koppers Inc. is vigorously defending these cases, an unfavorable resolution of these matters may have a material adverse effect on the Company’s business, financial condition, cash flows and results of operations.

Grenada—All Cases. Koppers Inc., together with various co-defendants (including Beazer East), has been named as a defendant in toxic tort lawsuits in state court in Mississippi (see Grenada—State Court Cases below) and in federal court in Mississippi (see Grenada—Federal Court Cases below) arising from the operation of the Grenada facility. The complaints allege that plaintiffs were exposed to harmful levels of various toxic chemicals, including creosote, pentachlorophenol, polycyclic aromatic hydrocarbons and dioxin, as a result of soil, surface water and groundwater contamination and air emissions from the Grenada facility and, in some cases, from an adjacent manufacturing facility operated by Heatcraft, Inc. Based on the experience of Koppers Inc. in defending previous toxic tort cases, the Company does not believe that the damages sought by the plaintiffs in the state and federal court cases are supported by the facts of the cases. Other than for cases in which a verdict has been rendered (see Grenada—Federal Court Cases below), the Company has not provided a reserve for these lawsuits because, at this time, it cannot reasonably determine the probability of a loss, and the amount of loss, if any, cannot be reasonably estimated. Although Koppers Inc. intends to vigorously defend these cases, there can be no 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. See “Environmental and Other Liabilities Retained or Assumed by Others.”

Beck Case—The complaint in this case was originally filed by approximately 110 plaintiffs. Pursuant to an order granting defendants’ motion to sever, the court dismissed the claims of 98 plaintiffs in the Beck case without prejudice to their right to re-file their complaints. In December 2005, 94 of the 98 plaintiffs in the Beck case whose claims were dismissed re-filed their complaints. The plaintiffs in the 94 cases that were re-filed seek compensatory damages from the defendants of at least $5.0 million for each of eight counts and punitive damages of at least $10.0 million for each of three counts (in addition to damages for an unspecified amount for alleged trespass and nuisance). No discovery orders have been issued with respect to the 94 additional cases. The claims of the 12 plaintiffs whose claims were not dismissed are still pending. The 12 remaining plaintiffs seek compensatory damages from the defendants in an unspecified amount and punitive damages of $20.0 million for each of four counts. The court ordered that the claims of the 12 remaining Beck plaintiffs must be tried separately.

The first of these trials commenced on April 17, 2006, and the jury returned a verdict of 20% of $845,000 against Koppers Inc. for compensatory damages and no liability for punitive damages. Subsequent to the verdict, the court reduced the compensatory damages judgment by $60,000 to $785,000. The Company accrued its portion of the verdict in the first quarter of 2006. Koppers Inc. has appealed the judgment entered against it to the United States Court of Appeals for the Fifth Circuit.

The briefing schedule for the appeal has not yet been set. The remaining 11 trials have been stayed pending the appeal by Koppers Inc. of the judgment entered in the first case.

Ellis Case—There are approximately 1,130 plaintiffs in this case. Each plaintiff seeks compensatory damages from the defendants of at least $5.0 million for each of seven counts and

punitive damages of at least $10.0 million for each of three counts (in addition to damages for an unspecified amount for trespass and nuisance). The Ellis complaint also requests injunctive relief. Discovery in this case has been stayed pending the completion of the trials for the 12 plaintiffs in the Beck case.

Grenada—State Court Cases. In the state court cases, which currently include a total of approximately 235 plaintiffs, each plaintiff seeks compensatory damages from the defendants of at least $5.0 million for each of up to eight counts and punitive damages of at least $10.0 million for each of three counts. Certain plaintiffs also seek damages for alleged trespass and private nuisance in unspecified amounts together with injunctive relief. The Mississippi Supreme Court ordered that all pending state court cases filed in counties other than Grenada County be transferred to Grenada County before they may be pursued. Plaintiffs’ counsel has transferred five such cases to Grenada County, but has not transferred the remaining cases. Until such cases are transferred, discovery in such cases is stayed.

With respect to the state court case that was originally filed on behalf of 95 plaintiffs in Grenada County, the court granted the defendants’ motion to sever the claims of these plaintiffs for improper joinder and set a period of time for the plaintiffs to re-file individual complaints or have their complaints dismissed. These plaintiffs (together with seven new plaintiffs) have filed their individual complaints in Grenada County and discovery in their cases is proceeding. These plaintiffs are included in the total of approximately 235 plaintiffs shown above.

Expense for 2006 primarily consists of the amount of the verdict rendered against Koppers Inc. in May 2006 related to the Grenada litigation and other costs related to the NZCC matter. Cash expenditures for 2006 consisted of the Company’s penalty related to the NZCC matter.

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. The Company’s subsidiaries expect to incur substantial costs for ongoing compliance with such laws and regulations. The Company’s subsidiaries 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.

The Company has agreements with former owners of certain of its operating locations under which the former owners retained, assumed and/or agreed to indemnify the Company against certain environmental and other liabilities. The most significant of these agreements was entered into at Koppers Inc.’s formation on December 29, 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 the Company 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 and liabilities related to products sold by Beazer East 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 the Company) 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 Inc. with regard to certain environmental, product and other liabilities and imposes certain conditions on Koppers Inc. before receiving such indemnification, including, in some cases, certain limitations regarding the time period as to which claims for indemnification can be brought. In July 2004, Koppers Inc. and Beazer East agreed to amend the environmental indemnification provisions of the December 29, 1988 asset purchase agreement to extend the indemnification period for pre-closing environmental liabilities through July 2019. As consideration for the amendment, Koppers Inc. agreed to pay Beazer East a total of $7.0 million in four installments over three years and to share toxic tort litigation defense costs arising from any sites acquired from Beazer East. The first three payments of $2.0 million each were made in July 2006, 2005 and 2004, respectively. The final payment of $1.0 million is due to be paid by the Company to Beazer East on July 1, 2007. The July 2004 amendment did not change the provisions of the Indemnity with respect to indemnification for non-environmental claims, such as product liability claims, which claims may continue to be asserted after July 2019.

Qualified expenditures under the Indemnity are not subject to a monetary limit. Qualified expenditures under the Indemnity include (i) environmental cleanup liabilities required by third parties, such as investigation, remediation and closure costs, relating to pre-December 29, 1988, or Pre-Closing, acts or omissions of Beazer East or its predecessors, (ii) environmental claims by third parties for personal injuries, property damages and natural resources damages relating to Pre-Closing acts or omissions of Beazer East or its predecessors, (iii) punitive damages for the acts or omissions of Beazer East and its predecessors without regard to the date of the alleged conduct and (iv) product liability claims for products sold by Beazer East or its predecessors without regard to the date of the alleged conduct. If the third party claims described in sections (i) and (ii) above are not made by July 2019, Beazer East will not be required to pay the costs arising from such claims under the Indemnity. However, with respect to any such claims which are made by July 2019, Beazer East will continue to be responsible for such claims under the Indemnity beyond July 2019.

Contamination has been identified at most of the Company’s manufacturing and other sites. Three sites currently owned and operated by the Company in the United States are listed on the National Priorities List promulgated under the Comprehensive Environmental Response, Compensation, and

Liability Act of 1980, as amended, (“CERCLA”). Currently, at the properties acquired from Beazer East (which include all of the National Priorities List sites and all but one of the sites permitted under the Resource Conservation and Recovery Act, (“RCRA”)), 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 at some of these sites.

To date, the parties that retained, assumed and/or agreed to indemnify the Company against the liabilities referred to above, including Beazer East, 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 $13.4 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 the Company 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. Furthermore, the Company could be required to record a contingent liability on its balance sheets with respect to such matters, which could result in its having significant additional negative net worth.

Domestic Environmental Matters. The Illinois Environmental Protection Agency (the “IEPA”), has requested that Koppers Inc. conduct a voluntary investigation of soil and groundwater at its Stickney, Illinois carbon materials and chemicals facility. The IEPA advised Koppers Inc. that it made such request as a result of a reported release of oil-like material from Koppers Inc.’s property into an adjacent river canal. Koppers Inc. has agreed to conduct such investigation in cooperation with Beazer East and intends to seek contribution and/or indemnification from third parties with respect to a portion of such costs. The preliminary results of the site investigation are expected to be available in the fourth quarter of 2006 and will be subject to further analysis and assessment by the Company, Beazer East and the IEPA.

In October 1996, the Company received a Clean Water Act (CWA) information request from the 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. The EPA alleged that the Company violated various provisions of the CWA. The Company subsequently entered into a Consent Decree and agreed, among other things, to a $2.9 million settlement, payable in three annual installments which was paid in full by April 2005. In 2005 the Company filed to terminate the Consent Decree at which time the EPA informed the Company that it will seek civil penalties for any CWA violations from 2001 to 2005 concurrent with the termination of the Consent Decree.

In August 2005, Koppers Inc. received a CWA information request from Region 4 of the EPA. Region 4 encompasses six of the Company’s facilities, of which four are currently operating. 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 as well as engineering studies and a limited number of specific inspection records. The Company is cooperating with the EPA and is developing certain information for the EPA’s review. The Company has not provided a reserve for this matter because at this time it cannot reasonably determine the probability of loss, and the amount, if any, cannot reasonably be estimated.

In August 2005, the Pennsylvania Department of Environment Protection, (the “PADEP”), proposed a fine of $1.3 million related to alleged water discharge exceedances from a storm water sewer pipe at the Company’s tar distillation facility in Clairton, Pennsylvania. The Company has proposed to undertake certain engineering steps at a cost of approximately $1.5 million to address this matter pursuant to a consent order the Company is currently discussing with the PADEP. The Company intends to cooperate with the PADEP to resolve this matter.

For the above matters, the Company has reserved $1.4 million of which $0.8 was reserved in the third quarter of 2006 and $1.0 million was reserved in 2006. The Company believes this is a reasonable approximation of the probable settlements with the various environmental authorities or its portion of costs to conduct site investigation work.

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 the EPA, which resulted in a complaint against the Company by the 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. Sentencing occurred in December 2002 and fines and penalties totaling $3.0 million were paid by January 2005. While the plea agreement has terminated, the compliance agreement remains in place. A failure on the Company’s part to comply with the terms of the compliance agreement could lead to significant additional costs and sanctions, including the potential for suspension or debarment from governmental contracts.

Australasian Environmental Matters. Soil and groundwater contamination has been detected at certain of the Company’s Australasian facilities. At the Company’s tar distillation facility in New Castle, New South Wales, Australia, soil contamination from an abandoned underground coal tar pipeline and other groundwater contamination has been detected at a property adjacent to the facility. The Company and the owner of the property are performing investigation work on remediation methods and expect to share in the cost of such remediation. Other environmental matters include the disposal of waste materials identified at the Company’s wood protection chemicals operations in Trentham, Victoria, Australia and New Zealand and soil remediation and a site investigation of groundwater at the wood products facility in Hume, Australia. Total reserves at September 30, 2006 include $2.1 million for these Australasian sites, of which $0.6 million was reserved in the third quarter of 2006 and $1.0 million was reserved in 2006.

Cautionary Statement Under the Private Securities Litigation Reform Act of 1995

The following discussion and analysis of the Company’s financial condition and results of operations should be read in conjunction with the unaudited financial statements and related notes included in Item 1 of this Part I as well as the Company’s audited Consolidated Financial Statements and the related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Koppers’ actual results may differ materially from those anticipated in these forward-looking statements due to many factors, including but not limited to those under the headings “Risk Factors” and “Forward-Looking Information.”

Koppers is a leading integrated global provider of carbon compounds and commercial wood treatment products. The Company’s products are used in a variety of niche applications in a diverse range of end-markets, including the aluminum, railroad, specialty chemical, utility, rubber and steel industries. Koppers serves its customers through a comprehensive global manufacturing and distribution network, which includes manufacturing facilities located in North America, Australasia, China, Europe and South Africa.

The Company operates two principal businesses, Carbon Materials & Chemicals and Railroad & Utility Products. Through the Company’s Carbon Materials & Chemicals business (62% of 2006 net sales), Koppers believes it is the largest distiller of coal tar in North America, Australia, the United Kingdom and Scandinavia. The Company processes coal tar into a variety of products, including carbon pitch, creosote and phthalic anhydride, which are critical intermediate materials in the production of aluminum, the pressure treatment of wood and the production of plasticizers and specialty chemicals, respectively. Through its Railroad & Utility Products business (38% of 2006 net sales), Koppers is the largest North American supplier of railroad crossties. The Company’s other commercial wood treatment products include the provision of utility poles to the electric and telephone utility industries.

Trend Overview. The Company’s businesses and results of operations are impacted by various competitive and other factors including (i) raw materials pricing and availability, in particular the amount and quality of coal tar available in global markets, which could be negatively impacted by the relative increase in the value of coal tar as a fuel source as a result of higher energy prices; (ii) competitive conditions in global carbon pitch markets, particularly the European carbon pitch markets; and (iii) low margins in the utility pole business.

Raw material prices have increased over the past several years, including the Company’s primary feedstocks: coal tar, coal and lumber. Many of the Company’s sales contracts include provisions which allow for price increases based on increases in the price of raw materials, which has allowed Koppers to generally maintain profit margins in its core businesses. The Company believes that the global restructuring of the Carbon Materials & Chemicals business has stabilized with respect to the North American and European markets, and that future expansion of the aluminum (and carbon pitch) markets will be primarily in Asian and Middle Eastern countries. Koppers expects to expand into these markets to the extent that the economics justify such expansion. Utility pole markets are expected to continue to remain competitive with resulting low margins; the Company will continue to review under-performing assets and rationalize capacity as necessary to remain competitive in this market and to reduce market share if warranted. Net sales over the past several years have been significantly impacted by favorable foreign exchange rates in Australia, Denmark and the United Kingdom; in the event this trend reverses, net sales could decline significantly if volumes do not increase.

Impact of Reilly Acquisition. The Company anticipates additional revenues of $70-$80 million on an annualized basis as the result of the purchase of certain assets of the coal tar business of Reilly Industries, Inc. on April 28, 2006. As the increased production is integrated into existing facilities, savings are expected to be realized on capacity utilization.

Due to a shortfall in anticipated coal tar raw materials in North America caused by a combination of factors including an extended strike as well as reduced coke production at two suppliers, Koppers has issued force majeure letters to its North American carbon materials customers. Management is taking steps to increase the sourcing of coal tar raw materials through its global procurement network as well as exploring alternate petroleum-based products that can be added to coal tar to extend production quantities. At this time it is too early to predict the impact of this raw materials shortfall on the Company’s profitability; however, management believes that this condition is temporary since it believes that the combination of resumed coke production, increased imports and alternative petroleum-based raw material products should enable the Company to declare the end of force majeure by December 31, 2006.

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. Historically, the Company’s operating results have on average been significantly lower in the fourth and first calendar quarters as compared to the second and third calendar quarters. The Company expects this seasonality trend to continue in future periods.

Comparison of Results of Operations for the Quarters Ended September 30, 2006 and 2005.

Net Sales. Net sales for the three months ended September 30, 2006 increased from $269.6 million to $314.4 million, or 17%, due to higher sales for both Carbon Materials & Chemicals and Railroad & Utility Products. Net sales for Carbon Materials & Chemicals increased from $162.0 million to $203.6 million, or 26%, as a result of $21.2 million of net sales from the Reilly acquisition, and, excluding the effect of the Reilly sales, pricing increases for carbon pitch, carbon black feedstock, carbon black, phthalic anhydride and naphthalene of $6.3 million, or 13%, $2.2 million, or 24%, $2.3 million, or 29%, $7.9 million, or 34%, and $3.9 million, or 55%, respectively. Additionally, sales increased $3.3 million due to higher freight costs in the U.S. and $2.8 million due to foreign exchange rates. The price increases for carbon pitch, naphthalene and phthalic anhydride were due primarily to higher raw material costs. The price increase for carbon black feedstock was due primarily to higher oil prices. These increases were partially offset by lower carbon pitch volumes of $8.1 million, or 18%, and lower phthalic anhydride volumes of $2.7 million, or 11%. Carbon pitch volumes in the U.S. were lower by $5.7 million, or 24%, due to product mix changes and reduced coal tar supplies due to an extended strike by a supplier as well as reduced coke production at two suppliers. Carbon pitch volumes in Europe were lower by $2.1 million, or 18%, due to reduced shipments from Denmark primarily due to timing. Phthalic anhydride volumes were lower due to lower production volumes and lower demand. Net sales for Railroad & Utility Products increased from $107.6 million to $110.8 million, or 3%, compared to the prior year due primarily to increases in prices for railroad crossties and treating services of $1.5 million, or 3%, and $3.1 million, or 20%, respectively, partially offset by lower volumes of crossties of $2.4 million, or 3%.

Gross Margin after Depreciation and Amortization. Gross profit after depreciation and amortization was $48.0 million compared to $38.7 million in the prior year quarter. As a percent of net sales, gross profit after depreciation and amortization increased from 14.4% to 15.3% as both segments had higher margins. Gross profit after depreciation and amortization for Carbon Materials & Chemicals increased to $33.8 million from $25.4 million in the prior year quarter. Gross margin for Carbon Materials & Chemicals increased from 15.7% to 16.6% due primarily to higher margins for phthalic anhydride and carbon black feedstock due to higher prices as noted above, as well as higher capacity utilization in the U.S. due to the integration of the Reilly Industries, Inc. assets from the acquisition in April 2006. These increases were partially offset by $1.9 million of legal and environmental charges compared to $1.3 million of legal and environmental charges in the prior year quarter, including $0.7 million of NZCC charges (see Note 17 in the Notes to the Condensed Consolidated Financial Statements). Additionally, $0.4 million of profit was realized as a result of insurance reserve reversals based on the most recent actuarial valuation, compared to $1.1 million of reversals in the prior year quarter. Gross profit after depreciation and amortization for Railroad & Utility Products increased to $14.3 million from $13.2 million in the prior year quarter. Gross margin for Railroad & Utility Products increased from 12.3% to 12.9% due primarily to the sale of the Alorton plant in the second quarter of 2006, as well as higher capacity utilization due to the closure of the Montgomery, Alabama and Superior, Wisconsin facilities. $1.0 million of profit was realized as a result of insurance reserve reversals based on the most recent actuarial valuation, compared to $1.7 million of profit realized in the prior year period. Gross margin for 2005 was negatively impacted by $0.5 million of closure costs for the Montgomery, Alabama facility.

Depreciation and Amortization. Depreciation and amortization for the three months ended September 30, 2006 was slightly lower than the prior year quarter as lower depreciation as a result of the closure and impairment of the Montgomery, Alabama and Superior, Wisconsin facilities, respectively, as well as the sale of the Alorton, Illinois facility more than offset an increase in depreciation and amortization from the acquisition of certain assets of Reilly Industries, Inc. in April 2006.

Selling, General and Administrative Expense. Selling, general and administrative expense as a percent of net sales decreased to 5.1% from 6.2% due to lower legal expenses of $1.5 million (primarily in Australasia) compared to the prior year quarter.

Interest expense. Interest expense decreased as the completion of the Company’s initial public offering in February 2006 and the related use of the proceeds to redeem $101.7 million of the Senior Secured Notes more than offset increased interest expense from the loan related to the Reilly acquisition.

Income Taxes. The Company’s effective income tax rate of 34.5% for the three months ended September 30, 2006 was lower than the rate of 40.2% in the prior year period due primarily to the effect of a benefit recorded in anticipation of non-conventional fuel tax credits in the current year period and a non-deductible penalty in New Zealand in the prior year period, which was partially offset by greater tax expense in China (caused by a partial phase-out of a tax holiday there) in the current year period and greater U.S. tax expense on a larger amount of repatriated earnings in the current year period.

Net Income. Net income for 2006 compared to the same period last year increased due to higher prices for phthalic anhydride and carbon black feedstock as a result of higher oil prices; an increase in capacity utilization in the U.S. Carbon Materials & Chemicals business due to the integration of the Reilly Industries, Inc. production into the Company’s existing facilities; lower overhead due a reduction in legal expenses in Australasia; and a lower tax rate due primarily to a benefit recorded in anticipation of non-conventional fuel tax credits as noted above.

Comparison of Results of Operations for the Nine Months Ended September 30, 2006 and 2005.

Net Sales. Net sales for the nine months ended September 30, 2006 increased from $767.9 million to $876.9 million, or 14%, due to higher sales for both Carbon Materials & Chemicals and Railroad & Utility Products. Net sales for Carbon Materials & Chemicals increased from $463.4 million to $542.6 million due to $36.1 million of sales from the Reilly acquisition and, excluding the effect of the Reilly sales, pricing increases for carbon pitch, carbon black feedstock, naphthalene and phthalic anhydride of $16.5 million, or 12%, $9.5 million, or 49%, $7.0 million, or 32%, and $11.1 million, or 18%, respectively. Additionally, sales increased due to volume and pricing increases for carbon black of $2.2 million, or 10%, and $5.2 million, or 22%, respectively. The price increases for carbon pitch, naphthalene and phthalic anhydride were due primarily to higher raw material costs. The price increase for carbon black feedstock was due primarily to higher oil prices. Additionally, sales from the Lambson acquisition which occurred in April 2005 were $13.2 million compared to $7.8 million for the prior year period, and freight costs for the U.S. business increased by $6.5 million over the prior year quarter, due primarily to the force majeure contract declaration as a result of coal tar and carbon pitch shortages. These increases were partially offset by lower volumes for carbon pitch and naphthalene of $11.3 million, or 11%, and $6.1 million, or 26%, respectively, and $3.0 million due to lower foreign exchange rates, primarily in Australia. Carbon pitch volumes were lower due to reductions in the U.S. and China, and naphthalene volumes were lower due primarily to lower tar distillation volumes. Net sales for Railroad & Utility Products increased from $304.5 million to $334.3 million due primarily to increases in volumes and prices for railroad crossties of $8.9 million, or 9%, and $4.8 million, or 4%, respectively, coupled with increases for treating services volumes and prices of $2.4 million, or 6%, and $3.1 million, or 8%. Volumes increased as a result of increased maintenance programs by the railroads and mild weather conditions in the first quarter of 2006, which allowed for the procurement of an unusually high volume of untreated crossties for that quarter. Prices increased primarily as a result of higher raw material costs. Additionally, prices for distribution poles increased $7.1 million, or 17%, partially offset by volume reductions of $4.2 million, or 10%, as a result of targeting higher margin business.

Gross Margin after Depreciation and Amortization. Gross profit after depreciation and amortization increased to $121.5 million from $107.3 million in the prior year period. As a percent of net sales, gross profit after depreciation and amortization decreased to 13.9% from 14.0%. Gross margin decreased to 15.4% from 15.5% for Carbon Materials & Chemicals and decreased to 11.3% from 11.6% for Railroad & Utility Products. Gross profit after depreciation and amortization for Carbon Materials & Chemicals increased to $83.8 million from $71.8 million in the prior year period. Gross margin for Carbon Materials & Chemicals was positively impacted by higher margins for phthalic anhydride due to higher pricing as noted above, as well as higher capacity utilization in the U.S. due to the integration of the Reilly Industries, Inc. assets from the acquisition in April 2006. Gross margin for 2006 was negatively impacted by $2.4 million of environmental expense related to various locations compared to $1.0 million in the prior year period (see Note 17 in the Notes to the Condensed Consolidated Financial Statements). Gross margin for 2005 was negatively impacted by a $2.6 million charge for the NZCC penalty. Gross margin for 2005 was positively impacted by $1.1 million of insurance reserve reversals compared to $0.4 million of insurance reserve reversals in 2006. Gross profit after depreciation and amortization for Railroad & Utility Products increased to $37.9 million from $35.3 million in the prior year period. Gross margin for Railroad & Utility Products decreased due primarily to a charge of $1.6 million related to the disposition of the Alorton facility, partially offset by an increase in volumes and prices for railroad crossties and treating services, and the increase in prices for distribution poles noted above. Additionally, margins for the nine months ended September 30, 2006 were negatively impacted by product mix due to an 18% increase in volumes for lower margin untreated crossties coupled with a 7% decrease in higher margin treated crossties as compared to the prior year. Also, $1.0 million of profit was realized as a result of insurance reserve reversals compared to $1.7 million of profit realized in the prior year period for insurance reserve reversals.

Depreciation and Amortization. Depreciation and amortization for the nine months ended September 30, 2006 decreased slightly compared to the prior year as lower depreciation as a result of the closure and impairment of the Montgomery, Alabama and Superior, Wisconsin facilities, respectively, coupled with the sale of the Alorton facility, more than offset an increase in depreciation and amortization from the Reilly and Lambson acquisitions.

Selling, General and Administrative Expense. Selling, general and administrative expense as a percent of net sales decreased to 5.9% from 6.4% as the termination of the Saratoga Partners III, LP advisory services contract for $3.0 million in 2006 was offset by lower legal expenses in Australia and generally flat overhead expenses compared to the prior year despite a significant increase in sales in 2006.

Interest expense. Interest expense increased due primarily to a call premium of $10.1 million that the Company paid to redeem $101.7 million of the Senior Secured Notes, $1.1 million of bond consent fees, and write offs of $3.2 million of deferred financing costs in the first quarter of 2006 as a result of the completion of the Company’s initial public offering and the related use of the proceeds to redeem a portion of the Senior Secured Notes. The effect of these items was partially offset by lower interest expense on the Senior Secured Notes as a result of the redemption.

Income Taxes. The income tax provision for the first nine months of 2006 reflects an estimated effective tax rate, exclusive of discrete items, of 34.5% as compared to an estimated effective tax rate, exclusive of discrete items, of 40.9% for the first nine months of 2005. The effective tax rate for the first nine months of 2006 differs from the U.S. federal statutory rate of 35.0% due to the recognition of non-conventional fuel tax credits (-10.9%) offset by taxes on foreign earnings (+8.0%) and other permanent items (+2.4%). With respect to the first nine months of 2005, the effective tax rate differs from the federal statutory rate due primarily to taxes on foreign earnings (+3.8%) and other permanent items (+2.1%). The first nine months of 2005 included a discrete tax item of $1.2 million related to a non-deductible penalty imposed by the New Zealand Commerce Commission (see Note 17 of the Notes to Condensed Consolidated Financial Statements).

Net Income. Net income for 2006 compared to the same period last year increased as $17.4 million of costs related to the Company’s initial public offering, along with a pretax loss of $1.6 million on the sale of the Alorton facility, were more than offset by higher profits from increases in pricing for phthalic anhydride, higher capacity utilization in the U.S. due to the integration of the Reilly Industries, Inc., an increase in volumes and prices for railroad crossties and treating services, improved pricing for distribution poles, a benefit recorded in anticipation of non-conventional fuel tax credits as noted above, and the impact of the NZCC penalty and environmental costs in the prior year as noted above.

Comparison of Results of Operations for the Quarters Ended September 30, 2006 and 2005.

Net Sales. North American sales increased by 28% due primarily to $21.2 million in sales from the Reilly acquisition. In addition, price increases (driven in part by higher raw material costs) of $10.0 million for carbon pitch and phthalic anhydride were partially offset by volume reductions for carbon pitch and phthalic anhydride of $8.3 million. Carbon pitch volumes were lower due to product mix changes and reduced coal tar supplies due to an extended strike by a supplier as well as reduced coke production at two suppliers. Australasian sales increased by 26% due primarily to $7.2 million for price increases for carbon pitch, naphthalene, carbon black feedstock and carbon black. The price increases for carbon pitch and carbon black were due primarily to higher raw material costs, and the higher volumes for carbon black were due to higher export sales. European sales increased by 21% due primarily to price increases of $6.8 million for carbon pitch, carbon black feedstock, benzole and naphthalene, partially offset by a $2.1 million reduction in carbon pitch volumes.

Operating Margin. North American operating margin increased due primarily to higher prices for phthalic anhydride and higher capacity utilization in the U.S. due to the integration of the Reilly Industries, Inc. assets from the acquisition in April 2006, which more than offset $0.8 million of environmental charges as well as the net decrease in profit from insurance reserve reversals of $0.7 compared to 2005. Operating margin for Australasia decreased due to higher raw material costs, $0.7 million of charges related to the NZCC anti-trust penalty, and $0.6 million of environmental expenses incurred in the third quarter of 2006. Operating margin for Europe was higher than the prior year due primarily to higher prices for carbon black feedstock and naphthalene.

Comparison of Results of Operations for the Nine Months Ended September 30, 2006 and 2005.

Net Sales. North American sales increased by 19% due primarily to $36.1 million in sales from the Reilly acquisition. In addition, price increases (driven in part by higher raw material costs) of $15.5 million for carbon pitch and phthalic anhydride, and higher freight costs of $6.5 million were partially offset by $9.7 million of volume decreases for carbon pitch and naphthalene. Australasian sales increased by 11% due primarily to $10.7 million of price increases for carbon pitch, carbon black

feedstock and naphthalene, as well as volume and pricing increases for carbon black of $2.2 million

and $5.2 million, respectively, which were partially offset by volume decreases of $4.6 million for

carbon pitch and naphthalene. The volume decreases were primarily the result of the plant fire in China in the first quarter which resulted in the suspension of operations for approximately three weeks, while the price increases for carbon pitch and naphthalene were due primarily to higher raw material costs. European sales increased by 21% due primarily to an incremental $5.5 million of sales from the April 2005 Lambson acquisition, along with price increases of $17.6 million for carbon pitch, carbon black feedstock and naphthalene. These increases were partially offset by volume decreases of $3.0 million for naphthalene and carbon black feedstock.

Operating Margin. North American operating margin increased due primarily to higher phthalic anhydride prices, higher capacity utilization in the U.S. due to the integration of the Reilly Industries, Inc. assets from the acquisition in April 2006, which were partially offset by $1.5 million of allocated costs for the buyout of the Saratoga advisory services contract, $0.7 million of additional insurance expense related to reserve reversals, and $0.9 million of environmental charges in 2006. Operating margin for Australasia increased as lower legal costs and higher prices for carbon black more than offset higher raw material costs and the impact of the plant fire in China. Additionally, 2005 margins were negatively impacted by $2.6 million of charges related to the NZCC penalty. Operating margin for Europe was higher than the prior year due primarily to higher prices for carbon black feedstock and higher carbon pitch prices in Denmark.

The Company completed an initial public offering on February 6, 2006, resulting in the issuance of 8,700,000 additional common shares at a price of $14.00 per share. Prior to the initial public offering, 2,288,481 shares of preferred stock were converted into 9,107,926 shares of common stock. Of such converted shares, 2,800,000 were sold in connection with the initial public offering and the related over-allotment option. The Company received approximately $111.2 million of net proceeds (after $10.6 million of expenses) from the issuance and sale of 8,700,000 of its common shares, which proceeds were used to redeem $101.7 million principal amount of the Koppers Inc. Senior Secured Notes on March 9, 2006, and pay a related a call premium of $10.1 million. The Company wrote off $3.2 million of deferred financing costs related to the buyback of the notes and incurred $1.1 million of bond consent fees. The call premium, write-off of deferred financing costs, and consent fees were recorded as interest expense. The Company also incurred $3.0 million for the termination of the Saratoga advisory services contract, which was recorded in selling, general and administrative expense. A post-IPO dividend of $8.2 million, the consent fees and the Saratoga termination fee were financed through borrowings under the revolving credit agreement.

The Company’s current dividend policy provides for quarterly dividend payments at an annual rate of $0.68 per share for the first full year following the completion of the initial public offering.

On November 18, 2004, Koppers Holdings issued and sold $203.0 million aggregate principal amount at maturity ($125.5 million gross proceeds) of 9⁷/8% Senior Discount Notes due 2014, (the “Senior Discount Notes”). Koppers Holdings has no direct operations and no significant assets other than the stock of Koppers Inc. No cash interest is required to be paid prior to November 15, 2009. The accreted value of each Senior Discount Note will increase from the date of issuance until November 15, 2009, at a rate of 9⁷/8% per annum compounded semiannually such that on November 19, 2009 the accreted value will equal $203 million, the principal amount due at maturity. Subsequent to November 19, 2009 cash interest on the Senior Discount Notes will accrue and be payable semi-annually in arrears on May 15 and November 15 of each year, commencing on May 15, 2010. The Senior Discount Notes are effectively subordinated to the Company’s existing and future

secured indebtedness, and are structurally subordinated to all of the existing and future indebtedness and other liabilities and preferred equity of the Company’s subsidiaries. The Senior Discount 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. The Company is currently in compliance with all covenants in the indenture governing the Senior Discount Notes.

Koppers Inc. is a party to an amended and restated credit agreement dated August 2005, which was amended in connection with the Company’s initial public offering in February 2006 and again in April 2006 in connection with the asset purchase from Reilly Industries, Inc. The credit agreement, as amended, provides for a revolving credit facility of up to $125.0 million and term loans of $59.0 million. The senior secured credit facility expires in December 2009, and the loans are secured by a first priority lien against substantially all of Koppers Inc.’s assets, including the assets of certain significant subsidiaries. Revolving credit availability is calculated based on receivable and inventory as well as the attainment of certain financial ratios and covenants.

The covenants that affect availability of the revolving credit facility and which may restrict the ability of Koppers Inc. to pay dividends include the following financial ratios:

On October 15, 2003 Koppers Inc. issued $320.0 million aggregate principal amount of 9⁷/8% Senior Secured Notes due 2013. 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 include customary covenants that restrict, among other things, the ability of Koppers Inc. and the subsidiary guarantors 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.

Koppers Inc. is currently in compliance with all covenants in the indenture governing the Senior Secured Notes and the agreement governing the senior secured credit facility.

Koppers Holdings depends on the dividends from the earnings of Koppers Inc. and its subsidiaries to generate the funds necessary to meet its financial obligations, including payments of principal, interest and other amounts on the Senior Discount Notes. The terms of Koppers Inc.’s senior secured credit facility as well as the terms of the indenture governing the Senior Secured Notes significantly restrict Koppers Inc. from paying dividends and otherwise transferring assets to Koppers Holdings. The amount of permitted dividends under both debt facilities is governed by a formula based on 50% of consolidated net income, among other things. Cash equity contributions from the sale of stock increase the amount available for dividends. At the time of the payment of the dividend, no event of default shall have occurred or be continuing under the indenture or the senior secured credit facility. Under the

indenture relating to the Senior Secured Notes, Koppers Inc. must have an EBITDA (as defined in the indenture) to consolidated interest expense ratio of at least 2.0 to 1.0. Additionally the senior secured credit facility requires compliance with all financial covenants and availability of at least $15 million under the revolving credit facility after giving effect to any proposed dividend. Significant reductions in net income or increases to indebtedness affecting compliance with financial covenants or availability under the senior secured credit facility would restrict Koppers Inc.’s ability to pay dividends. As of September 30, 2006, dividends available to be declared based on covenant restrictions under the Senior Discount Notes amounted to $118.8 million. As of September 30, 2006, dividends available to be declared based on covenant restrictions under the Senior Secured Notes amounted to $112.9 million.

The Company’s needs for cash in the next twelve months relate primarily to contractual obligations which include debt service, purchase commitments and operating leases, as well as for working capital, capital maintenance and acquisitions. The Company believes that its cash flow from operations and available borrowings under the senior secured credit facility 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 our expenditures and service our indebtedness, the Company would be required to raise additional funds.

As of September 30, 2006 the Company had $28.9 million of cash and cash equivalents and $49.9 million of unused revolving credit availability for working capital purposes after restrictions by various debt covenants and certain letter of credit commitments. As of September 30, 2006, $19.7 million of commitments were utilized by outstanding standby letters of credit. In addition, as of September 30, 2006, Koppers Inc. had outstanding term loans of $55.0 million under the credit facility.

On July 27, 2006 the Company’s board of directors declared a quarterly dividend of $0.17 per common share, paid on October 2, 2006 to shareholders of record as of September 1, 2006.

On November 2, 2006 the Company’s board of directors declared a quarterly dividend of $0.17 per common share, payable on January 2, 2007 to shareholders of record as of November 30, 2006.

Net cash provided by operating activities for the nine months ended September 30, 2006 decreased compared to the prior year quarter due primarily to the payment of a call premium of $10.1 million for the redemption of $101.7 million of the Senior Secured Notes, $1.1 million of bond consent fees, $3.0 million for the buyout of the Saratoga advisory services agreement, and $2.6 million for the NZCC settlement. Additionally, the increase in working capital in the first nine months of 2006 was $19.4 million higher than in the comparable period in 2005 due primarily to higher receivables and inventory, impacted by the Reilly acquisition as well as higher sales and higher raw material costs.

Net cash used in investing activities for the nine months ended September 30, 2006 increased primarily as a result of the Reilly acquisition, capital expenditures related to the Lambson acquisition in the United Kingdom, and the carbon black facility expansion in Australia.

Planned expansion at the Company’s carbon black facility in Australia is expected to result in capital expenditures of $8 to $10 million in 2006. Additionally, capital expenditures may be incurred in the future due to growth opportunities in existing markets in China. Capital expenditures in 2006 are expected to total approximately $34 million, including the carbon black facility expansion but excluding acquisitions.

Net cash provided by financing activities for the nine months ended September 30, 2006 was related to proceeds from the issuance of stock in the Company’s initial public offering of $121.8 million, used for the redemption of $101.7 million of the Senior Secured Notes due 2013, the payment of a

related call premium of $10.1 million, and the payment of $9.6 million of stock issuance expenses related to the offering. Also, a $40 million term loan was used to purchase certain assets from the Reilly carbon materials business. Additionally, borrowings of $10.0 million from the increase in Koppers Inc.’s term loan under its senior secured credit facility in February 2006 and $3.7 million of revolver borrowings were used to provide for $13.8 million of dividends, $1.1 million of bond consent fees, and $3.0 million for the buyout of the Saratoga advisory services contract. Net cash used in financing activities in 2005 was related to the payment of a $35 million dividend, and for debt repayments on the revolving credit facility and term loan, offset by new borrowing in the United Kingdom for the acquisition of Lambson.

On October 20, 2006 the Company’s coke plant in Monessen, Pennsylvania experienced a pipeline failure which interrupted operations. Repairs were completed and the plant became fully operational on October 30, 2006. The impact on fourth quarter pre-tax earnings is expected to be approximately $600,000-$800,000.

On April 19, 2006 the Company announced the cessation of operations at its wood treating facility in Superior, Wisconsin. The closure of the plant, which reported revenues of approximately $9.3 million in 2005, is expected to result in reduced costs and increased operating efficiencies for the Company since the majority of the sales and production will be transferred to two of the Company’s other existing wood treating facilities. The Company accrued $0.2 million of severance charges in 2006 related to the termination of approximately 20 employees. The Company incurred an asset impairment charge of $0.6 million related to this facility in the fourth quarter of 2005.

On June 22, 2006, the Company sold its specialty trackwork business and related assets located at the Company’s facility in Alorton, Illinois for cash of $1.9 million. This business was a component of the Railroad & Utility Products segment. The Company recorded a loss on disposal, before tax, of $1.6 million which is recorded as a component of cost of sales. Sales contributed by the business unit for the nine months ended September 30, 2006 and 2005 were $3.2 million and $5.8 million, respectively.

Operating profit for the nine months ended September 30, 2006 and 2005 was ($0.5) million and ($0.2) million, respectively. Sales and operating profit for the three months ended September 30, 2005 were $2.0 million and $0.1 million, respectively.

On April 28, 2006 the Company acquired certain assets of Reilly Industries, Inc.’s (“Reilly”) carbon materials business for an aggregate purchase price of $45.1 million which was primarily funded by a $40.0 million term loan with an existing bank group, cash and a current payable to Reilly for working capital adjustments. The purchased assets consist primarily of inventories, customer sales contracts, raw material supply contracts, railcar leases and a non-compete agreement. The Company is integrating the additional tar distillation production at its existing facilities in the U.S. Results of operations for the three and nine months ended September 30, 2006 include the Reilly assets from the date of acquisition. Net sales related to the Reilly acquisition for the three and nine months ended September 30, 2006 amounted to $21.2 million and $36.1 million, respectively.

In January 2004 Koppers Inc. 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 three and nine months ended September 30, 2006 was to increase interest expense by approximately $0.1 million and $0.2 million, respectively. The fair value of the swap agreement at September 30, 2006 was a liability of approximately $2.5 million.
