NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note A — General

The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles for interim financial reporting and Securities and Exchange Commission regulations, but are subject to any year-end adjustments that may be necessary. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Results of operations for the period ended September 30, 2004 are not necessarily indicative of results to be expected for the year ending December 31, 2004. These financial statements should be read in conjunction with the audited financial statements and related notes thereto as of and for the year ended December 31, 2003 included in Arch Coal, Inc.’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission.

Arch Coal, Inc. (the “Company”) is engaged in the production of steam and metallurgical coal from surface and deep mines throughout the United States, for sale to electric generation, industrial and export markets. The Company’s mines are primarily located in the Powder River Basin, Central Appalachia and Western Bituminous region of the United States. All subsidiaries (except as noted below) are wholly owned. Intercompany transactions and accounts have been eliminated in consolidation.

The Company’s Wyoming, Colorado and Utah coal operations are included in a joint venture named Arch Western Resources, LLC (“Arch Western”). Arch Western is 99% owned by the Company and 1% owned by BP p.l.c. The Company also acts as the managing member of Arch Western.

As of and for the period ending July 31, 2004, the membership interests in the Utah coal operations, Canyon Fuel Company, LLC (“Canyon Fuel”), were owned 65% by Arch Western and 35% by a subsidiary of ITOCHU Corporation. Through July 31, 2004, the Company’s 65% ownership of Canyon Fuel was accounted for on the equity method in the Condensed Consolidated Financial Statements as a result of certain super-majority voting rights in the joint venture agreement. Income from Canyon Fuel through July 31, 2004 is reflected in the Condensed Consolidated Statements of Operations as income from equity investments (see additional discussion in Note E — “Equity Investments”). On July 31, 2004, the Company acquired the remaining 35% of Canyon Fuel. See Note B — “Business Combinations” for further discussion.

Note B — Business Combinations

Canyon Fuel 35% Acquisition

On July 31, 2004, the Company purchased the 35% interest in Canyon Fuel that it did not own from ITOCHU Corporation. The purchase price, including related costs and fees, of $112.0 million was funded with cash of $90.0 million and a five-year, $22.0 million non-interest bearing note. Net of cash acquired, the fair value of the transaction totaled $98.4 million. As a result of the acquisition, the Company owns substantially all of the ownership interests of Canyon Fuel and will no longer account for its investment in Canyon Fuel on the equity method but will consolidate Canyon Fuel in its financial statements. As of December 31, 2003, Canyon Fuel controlled approximately 161.0 million tons of low-sulfur coal reserves in Utah and produced approximately 13.0 million tons of coal in 2003. The results of operations of the Canyon Fuel mines are included in the Company’s Western Bituminous segment.

The preliminary purchase accounting allocation related to the acquisition has been recorded in the accompanying condensed consolidated financial statements as of, and for the period subsequent to, July 31, 2004. The final valuation of the assets acquired and liabilities assumed is expected to be finalized once third-party appraisals are completed. The Company expects the completion of these appraisals prior to year-end.

4

The following table summarizes the preliminary estimated fair values of the assets acquired and the liabilities assumed at the date of acquisition (dollars in thousands):

Amounts preliminarily allocated to coal supply agreements noted in the table above represent the liability established for below-market coal supply agreements to be amortized over the remaining terms of the contracts. The liability is classified as an other noncurrent liability on the accompanying Condensed Consolidated Balance Sheet. The amortization period on these acquired coal supply agreements ranges from one to three years.

Triton Acquisition

On August 20, 2004, the Company acquired (1) Vulcan Coal Holdings, L.L.C., which owns all of the common equity of Triton Coal Company, LLC (“Triton”), and (2) all of the preferred units of Triton for a purchase price of $376.0 million, including transaction costs and subject to working capital adjustments. Prior to the acquisition, Triton was the nation’s sixth largest coal producer in 2003 and operated two mines in the Powder River Basin, North Rochelle and Buckskin. Following the consummation of the transaction, the Company completed the agreement to sell Buckskin to Kiewit Mining Acquisition Company (“Kiewit”). The net sales price for this second transaction was $72.9 million. The total purchase price, including related costs and fees, of $376.0 million was funded with cash of $254.0 million, including the proceeds from the Buckskin sale, $22.0 million in borrowings under the Company’s existing revolving credit facility and a $100.0 million term loan at its Arch Western Resources subsidiary. The purchase results in the integration of the North Rochelle mine with the Company’s existing Black Thunder mine in the Powder River Basin. The North Rochelle mine produced an estimated 23.9 million tons of coal in 2003 and its reserve base totaled an estimated 226.0 million tons of super-compliance coal at December 31, 2003.

The preliminary purchase accounting allocations related to the acquisition have been recorded in the accompanying condensed consolidated financial statements as of, and for the periods subsequent to, August 20, 2004. The final valuation of the assets acquired and liabilities assumed is expected to be finalized once third-party appraisals are completed. The Company expects the completion of these appraisals prior to year-end.

The following table summarizes the preliminary estimated fair values of the assets acquired and the liabilities assumed at the date of acquisition (dollars in thousands):

Amounts preliminarily allocated to coal supply agreements noted in the table above represent the value attributed to above-market coal supply agreements to be amortized over the remaining terms of the contracts. The amortization period on these acquired coal supply agreements ranges from one to seven years.

Included in the amounts allocated to accounts payable and accrued expenses noted in the table above are $4.8 million of liabilities incurred in connection with terminating Vulcan employees upon acquisition. Upon acquisition, the

5

Company identified 24 employees of Vulcan who were terminated as part of the integration of the North Rochelle mine into the Company’s Black Thunder mine. All amounts accrued for severance will be paid by the end of 2004.

Pro Forma Financial Information

The following unaudited pro forma financial information presents the combined results of operations of the Company, the remaining Canyon Fuel interest acquired from ITOCHU Corporation and the North Rochelle operations acquired from Triton, on a pro forma basis, as though the purchases had occurred as of the beginning of each period presented. The pro forma financial information does not necessarily reflect the results of operations that would have occurred had the Company and the operations acquired from Canyon Fuel and Triton constituted a single entity during those periods:

Note C — Coal Reserve Lease

On September 22, 2004, the U.S. Bureau of Land Management (“BLM”) accepted the Company’s bid of $611.0 million for a 5,084-acre federal coal lease known as Little Thunder, which is adjacent to the Company’s Black Thunder mine in the Powder River Basin. According to the BLM, the lease contains approximately 719.0 million mineable tons of high Btu, low-sulfur coal. The Company paid the first of five annual payments of $122.2 million under the lease using $22.2 million of cash on hand and $100.0 million borrowed under its revolving credit facility.

Note D — Adoption of FAS 143

On January 1, 2003, the Company adopted Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations (“FAS 143”). FAS 143 requires legal obligations associated with the retirement of long-lived assets to be recognized at fair value at the time the obligations are incurred. Upon initial recognition of a liability, that cost should be capitalized as part of the carrying amount of the related long-lived asset and allocated to expense over the useful life of the asset. Previously, the Company accrued for the expected costs of these obligations over the estimated useful mining life of the property.

The cumulative effect of the change on prior years resulted in a charge to income of $3.7 million (net of income taxes of $2.3 million), or $0.07 per share, which is included in the Company’s results of operations for the nine months ended September 30, 2003.

6

The following table describes the changes to the Company’s asset retirement obligation for the nine months ended September 30, 2004 and 2003:

Note E — Stock-Based Compensation

These interim financial statements include the disclosure requirements of Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation (“FAS 123”), as amended by Statement of Financial Accounting Standards No. 148, Accounting for Stock-Based Compensation — Transition and Disclosure (“FAS 148”). With respect to accounting for its stock options, as permitted under FAS 123, the Company has retained the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”), and related Interpretations. Had compensation expense for stock option grants been determined based on the fair value at the grant dates consistent with the method required by FAS 123, the Company’s net income (loss) available to common shareholders and earnings (loss) per common share would have been changed to the pro forma amounts as indicated in the following table:

7

Note F — Equity Investments

As of September 30, 2004, the Company no longer holds any equity investments. The Company purchased the remaining 35% interest in Canyon Fuel on July 31, 2004. Prior to July 31, 2004, the Company accounted for its investment in Canyon Fuel on the equity method. Additionally, prior to March 10, 2004, the Company accounted for its investment in Natural Resource Partners, LP (“NRP”) on the equity method. Amounts recorded in the Condensed Consolidated Financial Statements are as follows:

Investment in Canyon Fuel

The following table presents unaudited summarized financial information for Canyon Fuel:

Through July 31, 2004, the Company’s income from its equity investment in Canyon Fuel represents 65% of Canyon Fuel’s net income after adjusting for the effect of purchase adjustments related to its investment in Canyon Fuel. The Company’s investment in Canyon Fuel reflects purchase adjustments primarily related to the reduction in amounts assigned to sales contracts, mineral reserves and other property, plant and equipment. The purchase adjustments are amortized consistent with the underlying assets of the joint venture.

8

Effective January 1, 2003, Canyon Fuel adopted FAS 143 and recorded a cumulative effect loss of $2.4 million. The Company’s 65% share of this amount was offset by purchase adjustments of $0.5 million. These amounts are included in the cumulative effect of accounting change reported in the Company’s Condensed Consolidated Statements of Operations.

Investment in NRP

During the nine months ended September 30, 2004, the Company sold the majority of its remaining limited partnership units of NRP for proceeds of approximately $105.4 million. The sales resulted in a gain of $81.9 million. Subsequent to the sales, the Company’s remaining investment in NRP totals approximately 139 thousand units, representing 0.6% of NRP’s total equity interests. At this level of ownership, the investment is no longer accounted for on the equity method, but is accounted for in accordance with Statement of Financial Accounting Standards No. 115, Accounting for Certain Investments in Debt and Equity Securities (“FAS 115”). FAS 115 requires the investment to be marked to its market value at each reporting period. Because it is the Company’s intention to sell its remaining units, the units have been classified as trading securities. Changes in the value of trading securities are recorded as income or expense in the period of change. During the three and nine months ended September 30, 2004, the Company recorded a mark-to-market adjustment for its investment in NRP units as a gain of $0.3 million and $8.4 million, respectively. The mark-to-market adjustments are recorded as a component of other operating income in the accompanying Condensed Consolidated Statements of Operations. At September 30, 2004, the Company has classified its remaining investment in NRP as a current asset based on management’s intention to sell the investment within the next year.

Subsequent to September 30, 2004, the Company sold its remaining interest in NRP for proceeds of $6.1 million.

Prior to the March 2004 sale of limited partnership units, the Company recorded income under the equity method of accounting for its investment in NRP on a one-month lag. Equity income for the nine months ended September 30, 2004 of $2.4 million is for the period from December 2003 through February 2004.

Note G — Employee Benefit Plans

Defined Benefit Pension and Other Postretirement Benefit Plans

The Company has non-contributory defined benefit pension plans covering certain of its salaried and non-union hourly employees. Benefits are generally based on the employee’s years of service and compensation. The Company funds the plans in an amount not less than the minimum statutory funding requirements nor more than the maximum amount that can be deducted for federal income tax purposes.

The Company also currently provides certain postretirement medical/life insurance coverage for eligible employees. Generally, covered employees who terminate employment after meeting eligibility requirements are eligible for postretirement coverage for themselves and their dependents. The salaried employee postretirement medical/life plans are contributory, with retiree contributions adjusted periodically, and contain other cost-sharing features such as deductibles and coinsurance. The postretirement medical plan for retirees who were members of the United Mine Workers of America (“UMWA”) is not contributory. The Company’s current funding policy is to fund the cost of all postretirement medical/life insurance benefits as they are paid.

Components of Net Periodic Benefit Cost

The following table details the components of pension and other postretirement benefit costs.

9

Employer Contributions

The Company previously disclosed in its financial statements for the year ended December 31, 2003, that it expected to contribute $13 million to its pension plan in 2004. During the nine months ended September 30, 2004, the Company contributed 500,000 shares of its common stock to its pension plan (the pension plan subsequently sold the shares on the open market). The market value of the common stock on the date of contribution was $30.88 per share (resulting in a total contribution of $15.4 million). The Company presently does not anticipate contributing additional amounts to the pension plan in 2004.

Impact of Medicare Prescription Drug, Improvement and Modernization Act of 2003

On December 8, 2003, the President signed into law the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (“the Act”). The Act introduces a prescription drug benefit under Medicare (“Medicare Part D”) as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. The Company has included the effects of the Act in its financial statements for the nine months ending September 30, 2004 in accordance with FASB Staff Position No. FAS 106-2, Accounting and Disclosure Requirements related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (“FSP 106-2”). Incorporation of the provisions of the Act resulted in a reduction of the Company’s postretirement benefit obligation of $68.0 million. Postretirement medical expenses for fiscal year 2004 after implementation are expected to be $18.1 million less than that previously anticipated. Results for the nine months ending September 30, 2004 include $13.6 million of this total.

Note H — Other Comprehensive Income

Other comprehensive income items under FAS 130, Reporting Comprehensive Income, are transactions recorded in stockholders’ equity during the year, excluding net income and transactions with stockholders. The following table presents comprehensive income:

Other comprehensive income for the three and nine months ended September 30, 2004 and three months ended September 30, 2003 consists primarily of the reclassification of previously deferred mark-to-market losses from other comprehensive income to net income. Other comprehensive loss for the nine months ended September 30, 2003 consists of mark-to-market adjustments related to the Company’s financial derivatives positions for the period when those positions were deemed to be effective hedges and the reclassification of previously deferred mark-to-market losses from other comprehensive income to net income.

10

Note I — Inventories

Inventories consist of the following:

Note J — Debt

Debt consists of the following:

The Company has a $350.0 million revolving credit facility that matures on April 18, 2007. The rate of interest on borrowings under the credit facility is a floating rate based on LIBOR. The Company’s credit facility is secured by ownership interests in substantially all of its subsidiaries, except its ownership interests in Arch Western and its subsidiaries. At September 30, 2004, the Company had $68.9 million in letters of credit outstanding which, when combined with the $149.0 outstanding borrowings under the revolver, resulted in $132.1 million of unused borrowings under the revolver. Financial covenant requirements may restrict the amount of unused capacity available to the Company for borrowings and letters of credit.

On August 20, 2004, Arch Western borrowed $100.0 million under its term loan facility, which was established on September 19, 2003. Under the facility, the loan is due in quarterly installments from October 2004 through April 2007.

On July 31, 2004, the Company issued a five year, $22.0 million non-interest bearing note to help fund the Canyon Fuel acquisition. The promissory note is payable in quarterly installments beginning with a payment of $1.0 million in October 2004 and ending in July 2009. The note has been discounted to its present value of $18.2 million using a rate of 7.0%.

On June 25, 2003, Arch Western Finance, LLC, a subsidiary of Arch Western, completed the offering of $700 million of senior notes and utilized the proceeds of the offering to repay Arch Western’s existing term loans. The senior notes bear a fixed rate of interest of 6.75% and are due in full on July 1, 2013. Interest on the senior notes is payable on January 1 and July 1 each year commencing January 1, 2004. The senior notes are guaranteed by Arch Western and certain of Arch Western’s subsidiaries and are secured by a security interest in loans made to Arch Coal by Arch Western. The terms of the senior notes contain restrictive covenants that limit Arch Western’s ability to, among other things, incur additional debt, sell or transfer assets, and make investments.

11

Note K — Contingencies

The Company is a party to numerous claims and lawsuits with respect to various matters. The Company provides for costs related to contingencies when a loss is probable and the amount is reasonably determinable. After conferring with counsel, it is the opinion of management that the ultimate resolution of these claims, to the extent not previously provided for, will not have a material adverse effect on the consolidated financial position, results of operations or liquidity of the Company.

Note L — Transactions or Events Affecting Comparability of Reported Results

During the third quarter of 2004, the Company was notified by the IRS that it would receive additional black lung excise tax refunds and related interest from black lung claims that were originally denied by the IRS in 2002. The Company recognized a gain of $2.8 million ($2.1 million of principal and $0.7 million of interest) related to the claims. The $2.1 million principal amount was recorded as a reduction of cost of coal sales, while the $0.7 million interest amount was recorded as interest income.

During the first nine months of 2004, Canyon Fuel, which was accounted for under the equity method through July 31, 2004, began the process of idling its Skyline Mine (the idling process was completed in May 2004), and incurred severance costs of $3.2 million for the nine months ended September 30, 2004. The Company’s share of these costs totals $2.1 million, and is reflected in income from equity investments in the Condensed Consolidated Statements of Operations.

During the nine months ended September 30, 2004, the Office of Surface Mining completed an audit of certain of the Company’s federal reclamation fee filings for the period from 1998 through 2003. The audit resulted in the Company being assessed additional fees of $1.3 million and interest of $0.2 million. The additional fees have been recorded as a component of cost of coal sales in the accompanying Condensed Consolidated Statements of Operations, while the interest portion has been reflected as interest expense.

On June 25, 2003, Arch Western repaid its term loans with the proceeds from the offering of senior notes. The Company had designated certain interest rate swaps as hedges of the variable rate interest payments due under the Arch Western term loans. Pursuant to the requirements of Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities (“FAS 133”), historical mark-to-market adjustments related to these swaps through June 25, 2003 were deferred as a component of Accumulated Other Comprehensive Loss. Subsequent to the repayment of the term loans, these deferred amounts will be amortized as additional expense over the contractual terms of the swap agreements. For the three and nine months ending September 30, 2004, the Company recognized $2.1 million and $6.2 million, respectively, of expense related to the amortization of previously deferred mark-to-market adjustments. For the nine months ended September 30, 2003, the Company recognized $2.1 million of expense related to amortization of previously deferred mark-to-market adjustments and $4.8 million of expense related to early debt extinguishment costs. Additionally, subsequent to the repayment of the term loans, changes in market value of the interest rate swaps are recognized as income or expense. During the quarter and nine months ended September 30, 2003, the Company recognized income of $10.6 million and $11.6 million, respectively from changes in the market value of the swaps. These amounts are included in the line item “Other non-operating income” in the accompanying Condensed Consolidated Statements of Operations.

During the nine months ended September 30, 2003, the Company was notified by the State of Wyoming of a favorable ruling as it relates to the Company’s calculation of coal severance taxes. The ruling resulted in a refund of previously paid taxes and the reversal of previously accrued taxes payable. The impact on the three and nine months ended September 30, 2003 was a loss of $0.8 million and a gain of $2.5 million, respectively, which is reflected in cost of coal sales in the accompanying Condensed Consolidated Statements of Operations.

During the nine months ending September 30, 2003, the Company instituted ongoing cost reduction efforts throughout its operations. These cost reduction efforts included the termination of approximately 100 employees at the Company’s corporate office and Central Appalachia mining operations, resulting in severance and related expenses of $2.6 million during the nine months ended September 30, 2003. Of the expenses recognized, $1.6 million was recognized as a component of cost of coal sales, with the remainder recognized as a component of selling, general and administrative expenses.

During the three and nine months ended September 30, 2003, the Company recognized gains of $1.4 million and $2.9 million, respectively from sales of land at one of its idle properties. These amounts have been recorded as other operating income in the accompanying Condensed Consolidated Statements of Operations.

12

During the nine months ended September 30, 2003, the Company received $1.4 million from a customer that did not meet its 2002 contractual purchase requirements. This amount has been recorded as other operating income in the accompanying Condensed Consolidated Statements of Operations.

During the three and nine months ended September 30, 2003, the Company recognized income of $1.6 million resulting from the collection of receivables which had previously been estimated to be uncollectible and had been fully reserved in prior periods.

Note M — Earnings (Loss) per Share

The following tables sets forth the computation of basic and diluted earnings (loss) per common share from continuing operations.

13

For the nine month period ending September 30, 2003, employee stock options did not have a dilutive impact because the Company incurred losses in those periods. The Company’s Perpetual Cumulative Convertible Preferred Stock was not considered in the calculation of the number of diluted shares outstanding at September 30, 2003 because the assumed conversion of the preferred stock would have been antidilutive.

Note N — Guarantees

The Company holds a 17.5% general partnership interest in Dominion Terminal Associates (“DTA”), which operates a ground storage-to-vessel coal transloading facility in Newport News, Virginia. DTA leases the facility from Peninsula Ports Authority of Virginia (“PPAV”) for amounts sufficient to meet debt-service requirements. Financing is provided through $132.8 million of tax-exempt bonds issued by PPAV (of which the Company is responsible for 17.5%, or $23.2 million) which mature July 1, 2016. Under the terms of a throughput and handling agreement with DTA, each partner is charged its share of cash operating and debt-service costs in exchange for the right to use its share of the facility’s loading capacity and is required to make periodic cash advances to DTA to fund such costs. On a cumulative basis, costs exceeded cash advances by $13.9 million at September 30, 2004 (such amount is included in other noncurrent liabilities). Future payments for fixed operating costs and debt service are estimated to approximate $2.4 million annually through 2015 and $26.0 million in 2016.

In connection with the Company’s acquisition of the coal operations of Atlantic Richfield Company (“ARCO”) and the simultaneous combination of the acquired ARCO operations and the Company’s Wyoming operations into the Arch Western joint venture, the Company agreed to indemnify another member of Arch Western against certain tax liabilities in the event that such liabilities arise as a result of certain actions taken prior to June 1, 2013, including the sale or other disposition of certain properties of Arch Western, the repurchase of certain equity interests in Arch Western by Arch Western or the reduction under certain circumstances of indebtedness incurred by Arch Western in connection with the acquisition. Depending on the time at which any such indemnification obligation were to arise, it could have a material adverse effect on the business, results of operations and financial condition of the Company.

Note O — Segment Information

The Company produces steam and metallurgical coal from surface and deep mines for sale in electric generation, industrial and export markets. The Company operates only in the United States, with mines in the major low-sulfur coal basins. The Company has three reportable business segments, which are based on the coal basins in which the Company operates. Coal quality, coal seam height, transportation methods and regulatory issues are generally consistent within a basin. Accordingly, market and contract pricing have developed by coal basin. The Company manages its coal sales by coal basin, not by individual mine complex. Mine operations are evaluated based on their per-ton operating costs (which include all mining costs but exclude pass-through transportation expenses). The Company’s reportable segments are: Powder River Basin (PRB), Central Appalachia (CAPP) and Western Bituminous (WBIT). The Company’s operations in the Powder River Basin are located in Wyoming and include one operating surface mine (into which the North Rochelle mine was integrated) and one idle surface mine. The Company’s operations in Central Appalachia are located in southern West Virginia, eastern Kentucky, and Virginia and include 15 underground mines and eight surface mines. The Company’s Western Bituminous operations are located in Colorado, southern Wyoming and Utah and include four underground mines (one of which was idled in May 2004) and two surface mines (which were both put into reclamation mode in 2004).

Operating segment results for the three and nine months ending September 30, 2004 and 2003 are presented below. Results for the operating segments include all direct costs of mining. Corporate, Other and Eliminations includes corporate overhead, land management, other support functions, and the elimination of intercompany transactions.

Note P — Reclassifications

Certain amounts in the 2003 financial statements have been reclassified to conform with the classifications in the 2004 financial statements with no effect on previously reported net income (loss) or members’ equity.

Note Q — Subsequent Event

In October 2004, the Company completed the debt and equity offerings described below.

Debt Offering

On October 22, 2004, the Company issued $250.0 million of 6.75% Senior Notes due 2013 at a price of 104.75% of par. Interest on the notes is payable on January 1 and July 1 of each year, beginning on January 1, 2005. The proceeds from the issuance, net of the underwriters’ discount and related expenses, were $256.8 million. The debt offering was issued under an indenture dated June 25, 2003, to which the Company previously issued $700.0 million of 6.75% Senior Notes due 2013.

Equity Offering

On October 28, 2004, the Company completed a public offering of 7,187,500 common shares at $33.85 per share, including the underwriters’ over-allotment option. The proceeds from the offering, net of the underwriters’ discount and related expenses, were $230.6 million. The equity offering was made under the Company’s Universal Shelf Registration Statement on Form S-3.

Use of Proceeds

Net proceeds from the two offerings will be used primarily to repay Arch Western’s $100.0 million term loan and borrowings under the Company’s revolving credit facility. The balance of the net proceeds will be used for general corporate purposes, including the development of the Mountain Laurel mine complex in the Central Appalachia Basin.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

In this quarterly report, statements that are not reported financial results or other historical information are “forward-looking statements.” Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They are based on our management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements.

Forward-looking statements can be identified by the fact that they do not relate strictly to historic or current facts. They use words such as “anticipate,” “estimate,” “project,” “intend,” “plan,” “believe” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. In particular, these include statements relating to:

17

We cannot guarantee that any forward-looking statements will be realized, although we believe that we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and assumptions that may prove to be inaccurate. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove to be inaccurate, actual results could vary materially from those anticipated, estimated or projected.

RESULTS OF OPERATIONS

Acquisitions

On August 20, 2004, we acquired (1) Vulcan Coal Holdings, L.L.C., which owns all of the common equity of Triton Coal Company, LLC (“Triton”), and (2) all of the preferred units of Triton for a purchase price of $376.0 million, including transaction costs and subject to working capital adjustments. Immediately following the consummation of the transaction, we completed the agreement to sell the smaller of Triton’s two mines, Buckskin, to Kiewit Mining Acquisition Company (“Kiewit”), at a net sales price of $72.9 million. After completion of these transactions, we began the integration of the larger of Triton’s two mines, North Rochelle, with our existing Black Thunder mine in the Southern Powder River Basin.

On July 31, 2004, we purchased the remaining 35% interest in Canyon Fuel Company, LLC (“Canyon Fuel”) from ITOCHU Corporation for a purchase price of $112.0 million, including related costs and fees. Net of cash acquired, the fair value of the transaction totaled $98.4 million. As a result of the acquisition, we own substantially all of the ownership interests of Canyon Fuel and no longer account for our investment in Canyon Fuel on the equity method but consolidate Canyon Fuel in our financial statements subsequent to the July 31, 2004 purchase date.
