Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of Arch Coal, Inc. and its subsidiaries and controlled entities (the “Company”). The Company’s primary business is the production of steam and metallurgical coal from surface and underground mines located throughout the United States, for sale to utility, industrial and export markets. On June 15, 2011, the Company acquired International Coal Group, Inc. (“ICG”). The Company currently operates 18 mining complexes in West Virginia, Kentucky, Maryland, Virginia, Illinois, Wyoming, Colorado and Utah. All subsidiaries (except as noted below) are wholly-owned. Intercompany transactions and accounts have been eliminated in consolidation.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial reporting and U.S. Securities and Exchange Commission regulations. 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 three and six month periods ended June 30, 2012 are not necessarily indicative of results to be expected for the year ending December 31, 2012. These financial statements should be read in conjunction with the audited financial statements and related notes as of and for the year ended December 31, 2011 included in the Company’s Annual Report on Form 10-K/A filed with the U.S. Securities and Exchange Commission.

The Company owned a 99% membership interest and acted as the managing member in Arch Western Resources, LLC (“Arch Western”) a joint venture with Delta Housing, Inc., a subsidiary of BP p.l.c, Arch Western operates coal mines in Wyoming, Colorado and Utah. On April 9, 2012, Delta Housing, Inc. exercised their contractual right to require us to purchase their membership interests in Arch Western. The negotiated purchase amount of $17.5 million was paid on July 2, 2012.

2. Accounting Policies

There is no new accounting guidance that is expected to have a significant impact on the Company’s financial statements.

Less current maturities of debt and short-term borrowings	111,260		280,851
Long-term debt	$	4,464,351	$	3,762,297

The current maturities of debt include contractual maturities, as well as amounts borrowed that are supported by credit facilities that have a term of less than one year and amounts borrowed under credit facilities with terms longer than one year that the Company does not intend to refinance on a long-term basis, based on cash projections and management’s plans.

On May 16, 2012, the Company entered into an amendment to its senior secured revolving credit facility that amended certain financial maintenance covenants, suspending the Company’s compliance with the debt-to-EBITDA ratio, easing other financial covenants through September 2014 and adding defined minimum EBITDA targets. The maximum borrowing capacity of the revolving credit facility was reduced from $2 billion to $600 million. In conjunction with the amendment, the Company borrowed $1.4 billion under a six-year secured term loan facility, issued at a 1% discount. The term loan contains no financial maintenance covenants, is prepayable and is secured by the same assets as borrowings under the revolving credit facility. Quarterly principal payments of $3.5 million are due beginning in September 2012, plus interest at a rate of the greater of Libor or 1.25%, plus 450 basis points. The

Table of Contents

proceeds of the term loan were used to retire all outstanding borrowings under the revolving credit facility and the outstanding $450.0 million principal amount of 6 ¾% Senior Notes due 2013 issued by Arch Western Finance, LLC (“Arch Western Finance”), the Company’s indirect subsidiary.

On May 16, 2012, Arch Western Finance accepted for purchase an aggregate of approximately $304.0 million principal amount of its 6 ¾% Senior Notes due 2013 in an initial settlement pursuant to the terms of its tender offer and consent solicitation, which commenced on May 1, 2012, and called for redemption all of the remaining notes outstanding after the completion of the tender offer. The consideration for each $1,000 of principal purchased under the tender offer and consent solicitation was $1,002.50, for a total purchase consideration of $304.8 million. On May 30, 2012, the remaining notes with an outstanding principal amount of $146.0 million were redeemed at par value.

The Company incurred financing costs of $27.4 million in conjunction with the term loan, which have been deferred on the balance sheet. The Company wrote off $17.3 million of the $24.8 million of financing costs that had previously been deferred relating to the reduction in capacity of the senior secured revolving credit facility and $1.1 million related to the redemption of the 6 ¾% Senior Notes due 2013, offset by the $0.8 million of unamortized issue premium on the notes. The write-off of deferred financing fees, along with other transaction fees associated with these transactions is reflected in “Loss on extinguishment and refinancing of debt” in the condensed consolidated statements of operations.

At June 30, 2012, cash on hand was $512.5 million and availability was $345.0 million under our lines of credit.

4. Mine Closure and Asset Impairment Costs

An extreme downturn in demand for thermal coal resulted in the Company announcing on June 21, 2012 the closing of four mining complexes and the temporary idling of a fifth complex, all acquired with ICG, as well as cutbacks in production at other Appalachia mines. These actions resulted in a total workforce reduction of approximately 750 positions. The operations had ceased production prior to June 30, 2012, and will incur minimal ongoing annual maintenance costs customary with idling operations. The terms of customer contracts will be fulfilled by other operations.

The following costs are reflected in the line “Mine closure and asset impairment costs” on the condensed consolidated statements of operations for the three and six months ended June 30, 2012:

Parts and supplies inventory writedown	$	2,598
Impairment of property, plant and equipment	95,641
Impairment of coal properties and deferred development costs	403,279
Royalty obligations	11,546
Employee termination benefits	12,274
Pension, postretirement and occupational disease curtailment charge, net (see notes 11 and 12)	424
	$	525,762

The fair value of the closed or idled operations’ property, plant and equipment of approximately $51 million was based on the analysis of the marketability of thermal coal properties in the current market environment and our ability to redeploy equipment to other facilities.

The majority of the employee termination benefits will be paid in the third quarter of 2012. The royalty obligations represent minimum payments on various leases and will be paid over the remaining term of the leases, through 2016.

The announcement of the closures triggered an actuarial curtailment under the Company’s sponsored pension, post-retirement medical and black lung benefit programs. Certain employees were informed that they would be terminated effective August 21, 2012, which will trigger the recognition of the remaining pension plan curtailment impact in the third quarter of 2012, a curtailment benefit of $2.2 million.

5. Goodwill

A significant drop in the Company’s stock price during the second quarter of 2012, combined with continuing weak demand for thermal coal during the quarter and the Company’s resulting production cuts, indicated that the fair value of the Company’s goodwill could be less than its carrying value. Accordingly, the Company has performed the first step of the two-step goodwill impairment test as of June 30, 2012. The fair values of the reporting units are determined using a discounted cash flow (“DCF”) technique. A number of significant assumptions and estimates are involved in the application of the DCF analysis to forecast operating cash flows, including the discount rate and projections of sales volumes, selling prices and costs to produce.

Table of Contents

The value of the Company’s Black Thunder reporting unit in the Powder River Basin, where $115.8 million of goodwill had been allocated, is sensitive to thermal market demand. The further weakening in thermal coal markets in the second quarter significantly impacted the projected demand for and pricing of coal produced at Black Thunder. In step one of the goodwill impairment testing, the fair value of the Black Thunder reporting unit did not exceed its carrying value, primarily due to the impact of lower demand on near term sales volumes and pricing. The second step of the test requires that we determine the fair value of Black Thunder’s goodwill. This will involve determining the value of Black Thunder’s assets and liabilities. Based on initial estimates of the fair values of the assets and liabilities and the deficit of the fair value when compared to the related book values, we recorded a preliminary write-off of the entire $115.8 million of goodwill allocated to the Black Thunder reporting unit during the second quarter of 2012.

The goodwill amounts allocated to certain reporting units in the Company’s Appalachia segment are particularly sensitive to volatility in the demand for metallurgical coal. Should metallurgical coal markets weaken, affecting the volumes and pricing of metallurgical coal from the Company’s operations, it could cause the fair value of the reporting units to be less than their carrying value, requiring us to perform step 2 of the test for impairment.

6. Equity Investments and Membership Interests in Joint Ventures

The Company accounts for its investments and membership interests in joint ventures under the equity method of accounting if the Company has the ability to exercise significant influence, but not control, over the entity. Below are the equity method investments reflected in the condensed consolidated balance sheets:

Balance at June 30, 2012	$	—		$	34,817		$	—		$	5,047	$	—		$	—	$	39,864

The Company may be required to make future contingent payments of up to $73.0 million related to development financing for certain of its equity investees. The Company’s obligation to make these payments, as well as the timing of any payments required, is contingent upon a number of factors, including project development progress, receipt of permits and construction financing.

7. Derivatives

Diesel fuel price risk management

The Company is exposed to price risk with respect to diesel fuel purchased for use in its operations. The Company anticipates purchasing approximately 73 to 78 million gallons of diesel fuel for use in its operations during 2012. To protect the Company’s cash flows from increases in the price of diesel fuel for its operations, the Company uses forward physical diesel purchase contracts, as well as heating oil swaps and purchased call options. At June 30, 2012, the Company had protected the price of approximately 80% of its expected purchases for the remainder of fiscal year 2012 and 50% of its 2013 purchases. At June 30, 2012, the Company had purchased heating oil call options for approximately 71 million gallons for the purpose of managing the price risk associated with future diesel purchases.

During the first quarter of 2012, the Company determined the effectiveness of the heating oil options could not be established as of December 31, 2011 and on an ongoing basis. As a result, the amount remaining in accumulated other comprehensive income of $8.2 million, or $5.2 net of income taxes, was recorded in earnings, in the “other income, net” line on the condensed consolidated statement of income.

The Company also purchased heating oil call options to hedge the fuel surcharges on its barge and rail shipments that cover increases in diesel fuel prices. These positions reduce the Company’s risk of cash flow fluctuations related to these surcharges but the

Table of Contents

positions are not accounted for as hedges. At June 30, 2012, the Company held purchased call options for approximately 18.0 million gallons for the purpose of managing the fluctuations in cash flows associated with fuel surcharges on future shipments.

Coal risk management positions

The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market in order to manage its exposure to coal prices. The Company has exposure to the risk of fluctuating coal prices related to forecasted sales or purchases of coal or to the risk of changes in the fair value of a fixed price physical sales contract. Certain derivative contracts may be designated as hedges of these risks.

At June 30, 2012, the Company held derivatives for risk management purposes that are expected to settle in the following years :

(Tons in thousands)	2012	2013	2014	2015

Coal trading positions

The Company may sell or purchase forward contracts, swaps and options in the over-the-counter coal market for trading purposes. The Company is exposed to the risk of changes in coal prices on the value of its coal trading portfolio. The estimated future realization of the value of the trading portfolio is $0.6 million of gains in the remainder of 2012 and $2.1 million of losses in 2013.

Tabular derivatives disclosures

The Company’s contracts with certain of its counterparties allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Such netting arrangements reduce the Company’s credit exposure related to these counterparties. For classification purposes, the Company records the net fair value of all the positions with a given counterparty as a net asset or liability in the consolidated balance sheets. The amounts shown in the table below represent the fair value position of individual contracts, and not the net position presented in the accompanying condensed consolidated balance sheets. The fair value and location of derivatives reflected in the accompanying condensed consolidated balance sheets are as follows:

Based on fair values at June 30, 2012, gains on derivative contracts designated as hedge instruments in cash flow hedges of approximately $4.0 million are expected to be reclassified from other comprehensive income into earnings during the next twelve months.

8. Inventories

Inventories consist of the following:

	$	455,091	$	377,490

The repair parts and supplies are stated net of an allowance for slow-moving and obsolete inventories of $11.3 million at June 30, 2012, and $13.1 million at December 31, 2011.

9. Fair Value Measurements

The hierarchy of fair value measurements prioritizes the inputs to valuation techniques used to measure fair value. The levels of the hierarchy, as defined below, give the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

· Level 1 is defined as observable inputs such as quoted prices in active markets for identical assets. Level 1 assets include available-for-sale equity securities and coal futures that are submitted for clearing on the New York Mercantile Exchange.

· Level 2 is defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s level 2 assets and liabilities include commodity contracts (coal and heating oil) with fair values derived from quoted prices in over-the-counter markets or from prices received from direct broker quotes.

· Level 3 is defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. These include the Company’s commodity option contracts (coal and heating oil) valued using modeling techniques, such as Black-Scholes, that require the use of inputs, particularly volatility, that are rarely observable. Changes in the unobservable inputs would not have a significant impact on the reported Level 3 fair values at June 30, 2012.

The table below sets forth, by level, the Company’s financial assets and liabilities that are recorded at fair value in the accompanying condensed consolidated balance sheet:

	Fair Value at June 30, 2012
	Total		Level 1		Level 2		Level 3
	(In thousands)
Assets:
Investments in equity securities	$	8,035	$	8,035	$	—	$	—
Derivatives	60,195		51,701		1,650		6,844

Liabilities:
Derivatives	$	7,090	$	—	$	5,355	$	1,735

The Company’s contracts with certain of its counterparties allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. For classification purposes, the Company records the net fair value of all the positions with these counterparties as a net asset or liability. Each level in the table above displays the underlying contracts according to their classification in the accompanying condensed consolidated balance sheet, based on this counterparty netting.

The following table summarizes the change in the fair values of financial instruments categorized as level 3.

Table of Contents

	Three Months Ended			Six Months Ended

Net unrealized losses during the three and six month periods ended June 30, 2012 related to level 3 financial instruments held on June 30, 2012 were $12.4 million and $9.6 million, respectively.

Fair Value of Long-Term Debt

At both June 30, 2012 and December 31, 2011, the fair value of the Company’s debt, including amounts classified as current, was $4.2 billion. Fair values are based upon observed prices in an active market when available or from valuation models using market information.

10. Stock-Based Compensation and Other Incentive Plans

During the six months ended June 30, 2012, the Company granted options to purchase approximately1.3 million shares of common stock with a weighted average exercise price of $13.46 per share and a weighted average grant-date fair value of $5.31 per share. The options’ fair value was determined using the Black-Scholes option pricing model, using a weighted average risk-free rate of .759%, a weighted average dividend yield of 2.95% and a weighted average volatility of 60.48%. The options’ expected life is 4.5 years and the options vest ratably over three years, and provide for the continuation of vesting after retirement for recipients that meet certain criteria. The expense for these options will be recognized through the date that the employee first becomes eligible to retire and is no longer required to provide service to earn all or part of the award.

The Company has a long-term incentive program that allows for the award of performance units. The total number of units earned by a participant is based on financial and operational performance measures, and may be paid out in cash or in shares of the Company’s common stock. The Company recognizes compensation expense over the three-year term of the grant. Amounts accrued and unpaid for all grants under the plan totaled $8.6 million and $9.6 million as of June 30, 2012 and December 31, 2011, respectively.

13. Earnings per Common Share

The following table provides the basis for earnings per share calculations by reconciling basic and diluted weighted average shares outstanding:

	Three Months Ended June 30,		Six Months Ended June 30,
	2012	2011	2012	2011
	(In thousands)
Weighted average shares outstanding:
Basic weighted average shares outstanding	212,048	174,244	211,868	168,442
Effect of common stock equivalents under incentive plans	—	1,028	—	1,112
Diluted weighted average shares outstanding	212,048	175,272	211,868	169,554

The weighted effect of restricted stock, restricted stock units and options for 5.3 million and 1.1 million shares of common stock for the three month periods ended June 30, 2012 and 2011, respectively, and 4.5 million and 1.7 million shares for the six month periods ending June 30, 2012 and 2011, respectively, were excluded from the calculation of diluted weighted average shares outstanding because the effect would have been antidilutive. An additional weighted effect of 40,000 and 130,000 shares for the three and six month periods ending June 30, 2012, respectively, were excluded from the calculation of diluted weighted average shares outstanding because the Company incurred a loss for those periods.

14. Guarantees

The Company has agreed to continue to provide surety bonds and letters of credit for obligations, primarily reclamation, of Magnum Coal Company (“Magnum”) related to the properties the Company sold to Magnum on December 31, 2005. Patriot Coal Corporation (“Patriot Coal”) acquired Magnum in July 2008. The surety bonding amounts are mandated by the state and are not directly related to the estimated cost to reclaim the properties. At June 30, 2012, the Company had $35.3 million of surety bonds remaining related to properties sold to Magnum, however Patriot Coal has posted letters of credit of $16.7 million in the Company’s favor.

Table of Contents

Magnum would have acquired a contract to supply coal through 2017 to a customer that had not consented to the contract’s assignment from the Company to Magnum. The Company has committed to purchase coal from Magnum to supply to the customer at the same price the customer is charged for the sale. Under the coal supply contract, as amended, Magnum has the ability to buy out of its monthly obligations under the contract at prices that are predetermined for the remainder of the agreement. Additionally, a predecessor of the Company entered into a guarantee for the delivery of coal under a contract assigned to Magnum. If Magnum is unable to supply the coal for these coal sales contracts or pay the buy out amount if elected, and if the guarantee is enforceable, then the Company may be required to fulfill Magnum’s delivery or payment obligations. The maximum financial impact to the Company if required to fulfill Magnum’s obligations over the term of these contracts would be approximately $70.0 million as of June 30, 2012.

On July 9, 2012 Patriot Coal filed voluntary petitions for reorganization under Chapter 11 of the Bankruptcy Code, in order to undertake a comprehensive financial restructuring. Patriot has the expectation of continuing to serve customers, after receiving a commitment of debtor-in-possession financing. At this time, the Company does not believe that it is probable that it would have to purchase replacement coal, and, accordingly, no losses have been recorded in the consolidated financial statements as of June 30, 2012.

15. Contingencies

Allegheny Energy Supply (“Allegheny”), the sole customer of coal produced at the Company’s subsidiary Wolf Run Mining Company’s (“Wolf Run”) Sycamore No. 2 mine, filed a lawsuit against Wolf Run, Hunter Ridge Holdings, Inc. (“Hunter Ridge”), and ICG in state court in Allegheny County, Pennsylvania on December 28, 2006, and amended its complaint on April 23, 2007. Allegheny claimed that Wolf Run breached a coal supply contract when it declared force majeure under the contract upon idling the Sycamore No. 2 mine in the third quarter of 2006, and that Wolf Run continued to breach the contract by failing to ship in volumes referenced in the contract. The Sycamore No. 2 mine was idled after encountering adverse geologic conditions and abandoned gas wells that were previously unidentified and unmapped. After extensive searching for gas wells and rehabilitation of the mine, it was re-opened in 2007, but with notice to Allegheny that it would necessarily operate at reduced volumes in order to safely and effectively avoid the many gas wells within the reserve. The amended complaint also alleged that the production stoppages constitute a breach of the guarantee agreement by Hunter Ridge and breach of certain representations made upon entering into the contract in early 2005. Allegheny voluntarily dropped the breach of representation claims later. Allegheny claimed that it would incur costs in excess of $100 million to purchase replacement coal over the life of the contract. ICG, Wolf Run and Hunter Ridge answered the amended complaint on August 13, 2007, disputing all of the remaining claims.

On November 3, 2008, ICG, Wolf Run and Hunter Ridge filed an amended answer and counterclaim against the plaintiffs seeking to void the coal supply agreement due to, among other things, fraudulent inducement and conspiracy. On September 23, 2009, Allegheny filed a second amended complaint alleging several alternative theories of liability in its effort to extend contractual liability to ICG, which was not a party to the original contract and did not exist at the time Wolf Run and Allegheny entered into the contract. No new substantive claims were asserted. ICG answered the second amended complaint on October 13, 2009, denying all of the new claims. ICG’s counterclaim was dismissed on motion for summary judgment entered on May 11, 2010. Allegheny’s claims against ICG were also dismissed by summary judgment, but the claims against Wolf Run and Hunter Ridge were not. The court conducted a non-jury trial of this matter beginning on January 10, 2011 and concluding on February 1, 2011. At the trial, Allegheny presented its evidence for breach of contract and claimed that it is entitled to past and future damages in the aggregate of between $228.0 million and $377.0 million. Wolf Run and Hunter Ridge presented their defense of the claims, including evidence with respect to the existence of force majeure conditions and excuse under the contract and applicable law. Wolf Run and Hunter Ridge presented evidence that Allegheny’s damages calculations were significantly inflated because it did not seek to determine damages as of the time of the breach and in some instances artificially assumed future non-delivery or did not take into account the apparent requirement to supply coal in the future. On May 2, 2011, the trial court entered a Memorandum and Verdict determining that Wolf Run had breached the coal supply contract and that the performance shortfall was not excused by force majeure. ICG and Allegheny filed post-verdict motions in the trial court and on August 23, 2011, the court denied the parties’ motions. The court entered a final judgment on August 25, 2011, in the amount of $104.1 million, which included pre-judgment interest. The parties appealed the lower court’s decision to the Superior Court of Pennsylvania. Wolf Run and Hunter Ridge have filed an appeal bond in the amount of $124.9 million. Briefing is complete and oral argument was held on May 16, 2012. The matter is pending a decision by the Court.

As of June 30, 2012 and December 31, 2011, the Company had accrued $111.4 million and $108.3 million, respectively, for this lawsuit, including interest. The ultimate resolution of this matter could result in an outcome which may be materially different than what the Company has accrued.

In addition, 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 pending claims, other than as noted above, will not have a material adverse effect on the consolidated financial condition, results of operations or liquidity of the Company.

Coal sales increased in the second quarter of 2012 from the second quarter of 2011, due to an increase in the overall average price per ton sold. Higher pricing was partially the result of an increase in export shipments, some of which are priced on a delivered basis, increasing the sales price, but also increasing our transportation costs (see cost of sales discussion below). In addition, an increase in higher-priced metallurgical coal sales volumes from the contribution of the ICG operations, as well as the impact of changes in regional mix improved our average coal sales realizations. These factors were offset by the impact of lower thermal coal demand in all operating segments. We have provided more information about the tons sold and the coal sales realizations per ton by operating segment under the heading “Operating segment results”.

Costs, expenses and other. The following table summarizes costs, expenses and other components of operating income for the three months ended June 30, 2012 and compares it with the information for the three months ended June 30, 2011:

	$	1,652,522		$	890,174		$	(762,348	)	(85.6	)%

Cost of coal sales. Our cost of sales increased in the second quarter of 2012 from the second quarter of 2011 primarily from an increase in transportation costs as a result of the increase in export shipments and the impact of the acquisition of the ICG operations. We have provided more information about the performance and profitability of our operating segments under the heading “Operating segment results”.

Depreciation, depletion and amortization. When compared with the second quarter of 2011, higher depreciation, depletion and amortization costs in 2012 resulted primarily from the acquired ICG operations, partially offset by the impact of lower depreciation and amortization on assets amortized or depleted on the basis of tons produced, processed, or sold.

Amortization of acquired sales contracts, net. The fair values of acquired sales contracts are amortized over the tons of coal shipped during the term of the contracts. In the second quarter of 2011, amortization income related to the contracts we acquired with the ICG operations was offset by amortization expense related to contracts we acquired in 2009 with the Jacobs Ranch operations in the PRB.

Mine closure and asset impairment costs. The following costs are reflected in the line “Mine closure and asset impairment costs” for the three months ended June 30, 2012 relating to the closed Appalachia operations:

Table of Contents

	In millions
Parts and supplies inventory writedown	$	2.6
Impairment of property, plant and equipment	95.6
Impairment of coal properties and deferred development costs	403.3
Royalty obligations	11.6
Employee termination benefits	12.3
Pension, postretirement and occupational disease curtailment charge, net	0.4
	$	525.8

The majority of the employee termination costs will be paid in the third quarter. The operations had ceased production prior to June 30, 2012, and will incur minimal ongoing annual maintenance costs customary with idling operations. The terms of customer contracts will be fulfilled by other operations.

Goodwill Impairment. We recorded a preliminary write-off of our goodwill related to our Black Thunder mining complex during the second quarter of 2012 due to expectations of lower thermal coal demand and its impact on near-term sales volumes and pricing. The write-off will not be final until an allocation of fair value to individual and assets and liabilities is complete. See further discussion in Note 5 to the condensed consolidated financial statements in “Part I, Item 1. Financial Statements” of this Form 10-Q. Further weakening of coal markets, particularly metallurgical coal volumes and pricing could affect the value of goodwill allocated to complexes in Appalachia.

Selling, general and administrative expenses. Selling, general and administrative expenses increased compared with the second quarter of 2011. Our growth in the Appalachia operating region and through sales offices in Singapore and London has resulted in an increase in salary and benefit costs, travel costs, and other professional service fees. In addition, the change in our net obligation under the deferred compensation plan resulted in an increase in expense of $2.1 million. These were partially offset by a decrease in incentive compensation costs of $1.2 million.

Change in fair value of coal derivatives and coal trading activities, net. The gains reflected in the second quarter of 2012 relate primarily to API-2 positions entered into to manage price risk on physical export sales into Europe. These positions are not accounted for as hedges, so the change in the positions’ fair value prior to settlement is reflected in the results of operations.

Other operating income, net. When compared with the three months ended June 30, 2011, other operating income, net decreased in the three months ended June 30, 2012 primarily due to the following:

	In millions
Coal derivative settlements — risk management, non-hedges	$	8.5
Unrealized mark to market losses on diesel risk management program	(14.7		)
Commercial related income, net	3.4
Income from equity method investees	(1.8		)

We enter into derivative positions to manage price risk with respect to future coal sales and diesel purchases. Because we do not apply hedge accounting to these positions, the gains and losses from these activities may not be tied to the underlying activity in the statement of operations as if they qualified for hedge accounting.

Operating segment results. The following table shows results by operating segment for three months ended June 30, 2012 and compares it with the information for the three months ended June 30, 2011:

(1) Coal sales prices per ton exclude certain transportation costs that we pass through to our customers. We use these financial measures because we believe the amounts as adjusted better represent the coal sales prices we achieved within our operating segments. Since other companies may calculate coal sales prices per ton differently, our calculation may not be comparable to similarly titled measures used by those companies. In the second quarter of 2012, transportation costs per ton were $1.12 for the Powder River Basin, $12.37 for Appalachia and $17.77 for the Western Bituminous region. In the second quarter of 2011, transportation costs per ton were $0.26 for the Powder River Basin, $6.95 for Appalachia and $4.47 for the Western Bituminous region.

(2) Operating margin per ton sold is calculated as coal sales revenues less cost of coal sales, depreciation, depletion and amortization and sales contract amortization divided by tons sold.

(3) Adjusted EBITDA is defined as net income attributable to the Company before the effect of net interest expense, income taxes, depreciation, depletion and amortization and the amortization of acquired sales contracts. Adjusted EBITDA may also be adjusted for items that may not reflect the trend of future results. Segment Adjusted EBITDA is reconciled to net income at the end of this “Results of Operations” section.

Powder River Basin — Segment Adjusted EBITDA decreased in the second quarter of 2012 when compared to the second quarter of 2011 primarily due to the lower sales volumes in the Powder River Basin from our production cutbacks in response to the market conditions discussed previously. Per-ton costs were higher due to the lower production levels and higher diesel costs, which offset the impact of lower overall spending. Our total production costs were down in the second quarter of 2012 due to the redeployment of employees and equipment to significant reclamation activities performed during the quarter, reducing the number of contractors, and lower maintenance costs resulting from the idling of equipment. We expect this current cycle of reclamation to be largely completed in the third quarter.

Appalachia — Segment Adjusted EBITDA increased slightly from the second quarter of 2011 primarily as a result of an increase in the volumes and pricing of metallurgical-quality coal sold. We sold 1.9 million tons of metallurgical-quality coal in the second quarter of 2012 compared to 1.7 million tons in the second quarter of 2011. The volume contributions from the acquired ICG operations were partially offset by the impact of unfavorable market conditions, and the related production cutbacks and mine closings. Per-ton realizations in the second quarter of 2012 were slightly lower due to a lower percentage of metallurgical coal sales volumes in relation to total sales volumes. In addition, higher per-ton costs were impacted by higher cost production from operations acquired from ICG, lower production levels at other operations, and inflation in labor and commodity costs. Mine closure and asset impairment costs are excluded from the per-ton costs and operating margins above.

Western Bituminous —Segment Adjusted EBITDA decreased from the second quarter of 2011 due to lower sales volumes, due to weaker demand in the region. Longwall moves during the quarter were extended in response to market conditions. The Skyline mine will recommence longwall mining in October and the Dugout mine will begin mining its final longwall panel of the current seam in August. Future production decisions will be based on market conditions.

Net interest expense. The increase in interest expense during the second quarter of 2012 when compared with the second quarter of 2011 is the result of the ICG acquisition financing in 2011 and the refinancing transactions in the second quarter of 2012, discussed in the “Liquidity” section.

Other nonoperating expense. Amounts reported as nonoperating consist of expenses resulting from financing activities, other than interest costs. During the second quarter of 2012, nonoperating expense consists of the net loss resulting from the early retirement of $450.0 million principal amount of our subsidiary’s 6 ¾% Senior Notes due 2013. During 2011, nonoperating expense represents financing related costs of the ICG acquisition, including the cost to maintain a bridge financing facility, which was not utilized. See further description of financing activities in “Liquidity”.

Income taxes. Our effective income tax rate is sensitive to changes in and the relationship between annual profitability and the deduction for percentage depletion. The income tax benefit in the second quarter of 2012

reflects our pretax loss combined with percentage depletion deductions, offset by an increase in our valuation allowance against state tax loss carryforwards of approximately $8.0 million.

Six Months Ended June 30, 2012 Compared to Six Months Ended June 30, 2011

Summary. Our results during first half of 2012 when compared to the first half of 2011 were impacted substantially by our production cutbacks and mine closures in response to weak market conditions and the impact of the ICG acquisition.

Revenues. Our revenues consist of coal sales and revenues from our ADDCAR subsidiary acquired with ICG. The following table summarizes information about coal sales during the six months ended June 30, 2012 and compares it with the information for the six months ended June 30, 2011:

	Six Months Ended June 30,				Increase (Decrease)

Coal sales realization per ton sold	$	31.04	$	25.21	$	5.84		23.2	%

Coal sales increased in the first half of 2012 from the first half of 2011, due to an increase in the overall average price per ton sold, the result of improved pricing on metallurgical-quality coal sold and the increase in export sales, as well as the contribution from the ICG operations, including higher-priced metallurgical coal sales volumes, as well as the impact of changes in regional mix on our average coal sales realization. These factors were offset by lower thermal coal demand in all operating segments. We have provided more information about the tons sold and the coal sales realizations per ton by operating segment under the heading “Operating segment results”.

Costs, expenses and other. The following table summarizes costs, expenses and other components of operating income for the six months ended June 30, 2012 and compares it with the information for the six months ended June 30, 2011:

Cost of coal sales. Our cost of sales increased in the first half of 2012 from the first half of 2011 primarily from the impact of the acquisition of the ICG operations and an increase in transportation costs as a result of the increase in export shipments. We have provided more information about the performance and profitability of our operating segments under the heading “Operating segment results”.

Depreciation, depletion and amortization. When compared with the first half of 2011, higher depreciation, depletion and amortization costs in 2012 resulted primarily from the acquired ICG operations, partially offset by the impact of lower depreciation and amortization on assets amortized or depleted on the basis of tons produced, processed, or sold.

Amortization of acquired sales contracts, net. The fair values of acquired sales contracts are amortized over the tons of coal shipped during the term of the contracts. In the first half of 2011, amortization expense related to contracts we acquired in 2009 with the Jacobs Ranch operations in the PRB was offset by amortization income related to the contracts we acquired with the ICG operations.

Mine closure and asset impairment costs and goodwill impairment. These items are discussed in the results of operations for the three months ended June 30, 2012.

Selling, general and administrative expenses. Selling, general and administrative expenses were essentially flat when compared with the first half of 2011. Our growth in 2012 has resulted in an increase in salary and benefit costs, travel costs, and other professional service fees. These were offset by a decrease in incentive compensation costs of $3.8 million.

Change in fair value of coal derivatives and coal trading activities, net. The gains reflected in the first half of 2012 relate primarily to API-2 positions entered into to manage price risk on physical export sales into Europe. These positions are not accounted for as hedges, so the change in the positions’ fair value prior to settlement is reflected in the results of operations.

Other operating income, net. When compared with the six months ended June 30, 2011, other operating income, net increased in the six months ended June 30, 2012 primarily due to the following:

(1) Coal sales prices per ton exclude certain transportation costs that we pass through to our customers. We use these financial measures because we believe the amounts as adjusted better represent the coal sales prices we achieved within our operating segments. Since other companies may calculate coal sales prices per ton differently, our calculation may not be comparable to similarly titled measures used by those companies. In 2012, transportation costs per ton were $0.98 for the Powder River Basin, $12.34 for Appalachia and $12.93 for the Western Bituminous region. In 2011, transportation costs per ton were $0.19 for the Powder River Basin, $8.06 for Appalachia and $6.39 for the Western Bituminous region.

(2) Operating margin per ton sold is calculated as coal sales revenues less cost of coal sales, depreciation, depletion and amortization and sales contract amortization divided by tons sold.

Powder River Basin — Segment Adjusted EBITDA decreased in the first half of 2012 when compared to the first half of 2011, due to the lower sales volumes in the Powder River Basin from the production cutbacks in

Table of Contents

response to market conditions. Per-ton costs were also higher due to the lower production levels, which offset the impact of slightly higher per-ton selling prices.

Appalachia — Segment Adjusted EBITDA increased slightly from the first half of 2011 primarily as a result of an increase in the volumes and pricing of metallurgical-quality coal sold. We sold 3.5 million tons of metallurgical-quality coal in the first half of 2012 compared to 3.1 million tons in the first half of 2011. The volume contributions from the acquired ICG operations were offset by the impact of unfavorable market conditions. The benefit from higher per-ton realizations, net of sales sensitive costs, in the first half of 2012 was offset by the impacts of lower production levels and the extended longwall move at the Mountain Laurel complex in the first quarter of 2012, which resulted in an increase in our average per-ton production costs. Mine closure and asset impairment costs are excluded from the per-ton costs and operating margins above.

Western Bituminous — Segment Adjusted EBITDA decreased from the second quarter of 2011 due to lower sales volumes, due to weaker demand in the region. Longwall moves during the quarter were extended in response to market conditions. The Skyline mine will recommence longwall mining in October and the Dugout mine will begin mining its final longwall panel of the current seam in August. Future production decisions will be based on market conditions.

Reconciliation of Segment Adjusted EBITDA to Net Income

The discussion in “Results of Operations” includes references to our Adjusted EBITDA results. Adjusted EBITDA is defined as net income attributable to the Company before the effect of net interest expense, income taxes, depreciation, depletion and amortization and the amortization of acquired sales contracts. Adjusted EBITDA may also be adjusted for items that may not reflect the trend of future results. We believe that Adjusted EBITDA presents a useful measure of our ability to service and incur debt based on ongoing operations. Investors should be aware that our presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies. The table below shows how we calculate Adjusted EBITDA.

Liquidity and Capital Resources

Our primary sources of cash are coal sales to customers, borrowings under our credit facilities and other financing arrangements, and debt and equity offerings related to significant transactions. Excluding any significant mineral reserve acquisitions, we generally satisfy our working capital requirements and fund capital expenditures and debt-service obligations with cash generated from operations or borrowings under our lines of credit. The borrowings under these arrangements are classified as current if the underlying credit facilities expire within one year or if, based on cash projections and management plans, we do not have the intent to replace them on a long-term basis. Such plans are subject to change based on our cash needs.

On May 16, 2012, we entered into an amendment to our senior secured revolving credit facility that amended certain financial maintenance covenants, suspending our compliance with the debt-to-EBITDA ratio, easing other financial covenants through September 2014 and adding defined minimum EBITDA targets. The maximum borrowing capacity of the revolving credit facility was reduced from $2 billion to $600 million. In conjunction with the amendment, we borrowed $1.4 billion under a six-year secured term loan facility, issued at a 1% discount. The term loan contains no financial maintenance covenants, is prepayable and is secured by the same assets as borrowings under the revolving credit facility. Quarterly principal payments of $3.5 million are due beginning in September 2012, plus interest at a rate of the greater of Libor or 1.25%, plus 450 basis points. The proceeds of the term loan were used to retire all outstanding borrowings under the revolving credit facility and the outstanding $450.0 million principal amount of 6 ¾% Senior Notes due 2013 issued by Arch Western Finance, LLC (“Arch Western Finance”), the Company’s indirect subsidiary.

On May 16, 2012, Arch Western Finance accepted for purchase an aggregate of approximately $304.0 million aggregate principal amount of its 6 ¾% Senior Notes due 2013 in an initial settlement pursuant to the terms of its tender offer and consent solicitation, which commenced on May 1, 2012, and called for redemption all of the remaining notes outstanding after the completion of the tender offer. The consideration for each $1,000 of principal purchased under the tender offer and consent solicitation was $1,002.50, for a total purchase consideration of $304.8 million. On May 30, 2012, the remaining notes with an outstanding principal amount of $146.0 million were redeemed at par value.

We believe that cash generated from operations, cash on hand and borrowings under our credit facilities or other financing arrangements will be sufficient to meet working capital requirements and anticipated capital expenditures. As a result of the refinancing activities discussed previously, we have no significant debt maturities until 2016. Our ability to satisfy debt service obligations, to fund planned capital expenditures, to make acquisitions, to repurchase our common shares and to pay dividends will depend upon our future operating performance, which will be affected by prevailing economic conditions in the coal industry and financial, business and other factors, some of which are beyond our control.

At June 30, 2012, we had cash on hand of $512.5 million and availability of approximately $345.0 million under our lines of credit.

The Company’s average borrowing level under lines of credit and short term borrowings was approximately $297 million and $131 million for the three months ended June 30, 2012 and 2011, respectively and approximately $375 million and $100 million for the six months ended June 30, 2012 and 2011, respectively.

The following is a summary of cash provided by or used in each of the indicated types of activities during the six months ended June 30, 2012 and 2011.

	Six Months Ended June 30,
	2012			2011
	(Dollars in thousands)
Cash provided by (used in):
Operating activities	$	95,308		$	314,200
Investing activities	(192,866		)	(3,154,779		)
Financing activities	471,936			2,829,331

Cash provided by operating activities decreased in the first six months of 2012 compared to 2011, driven by lower operating income as well as an increase in inventories as a result of the weak market conditions.

We used less cash in investing activities in the first six months of 2012 compared to the amount used in 2011, primarily due to the acquisition of ICG in 2011, as well as a decrease in investments and prepaid royalties in 2012 . This was offset by an increase during the six months ended June 30, 2012 in capital expenditures of approximately $94 million when compared with 2011. We spent approximately $93 million during the first half 2012 on the development of the Leer mine. We have been able to reduce capital spending by deploying equipment from our idled operations into active ones, and into development projects like the Leer mine.

Cash provided by financing activities was approximately $472 million in the first six months of 2012, compared to approximately $2.8 billion in 2011. In 2011, the proceeds from the issuance of $2 million in senior notes in 2011 and an increase in shares outstanding as a result of the shares issued in 2011were used to finance the ICG acquisition. In 2012, the proceeds from the $1.4 billion term loan received in conjunction with the refinancing discussed previously were used, in part to retire the remaining outstanding senior secured notes due in 2013 and outstanding borrowings under lines of credit.

Ratio of Earnings to Fixed Charges

The following table sets forth our ratios of earnings to combined fixed charges and preference dividends for the periods indicated:

	Six Months Ended June 30,
	2012		2011
Ratio of earnings to combined fixed charges and preference dividends(1)	N/A	(2)	1.61	x

(1) Earnings consist of income from operations before income taxes and are adjusted to include only distributed income from affiliates accounted for on the equity method and fixed charges (excluding capitalized interest). Fixed charges consist of interest incurred on indebtedness, the portion of operating lease rentals deemed representative of the interest factor and the amortization of debt expense.

(2) Total losses for ratio calculation were $547.0 million and total fixed charges were $165.6 million for the six months ended June 30, 2012

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We manage our commodity price risk for our non-trading, thermal coal sales through the use of long-term coal supply agreements, and to a limited extent, through the use of derivative instruments. Sales commitments in the metallurgical coal market are typically not long-term in nature, and we are therefore subject to the fluctuations in the market pricing. We expect to sell a total of approximately 7.5 million tons of metallurgical coal in 2012.

At June 30, 2012, our commitments for 2012 and 2013 are as follows:

	2012			2013
	Tons	$ per ton		Tons	$ per ton

Powder River Basin
Committed, Priced	101.3	$	13.92	60.6	$	14.47

Committed, Unpriced Metallurgical	0.4			0.2

Illinois Basin
Committed, Priced	2.3	$	41.62	1.8	$	44.15

We are exposed to commodity price risk in our coal trading activities, which represents the potential future loss that could be caused by an adverse change in the market value of coal. Our coal trading portfolio included forward, swap and put and call option contracts at June 30, 2012. The estimated future realization of the value of the trading portfolio is $0.6 million of gains in the remainder of 2012 and $2.1 million of losses in 2013.

We monitor and manage market price risk for our trading activities with a variety of tools, including Value at Risk (VaR), position limits, management alerts for mark to market monitoring and loss limits, scenario analysis, sensitivity analysis and review of daily changes in market dynamics. Management believes that presenting high, low, end of year and average VaR is the best available method to give investors insight into the level of commodity risk of our trading positions. Illiquid positions, such as long-dated trades that are not quoted by brokers or exchanges, are not included in VaR.

VaR is a statistical one-tail confidence interval and down side risk estimate that relies on recent history to estimate how the value of the portfolio of positions will change if markets behave in the same way as they have in the recent past. While presenting VaR will provide a similar framework for discussing risk across companies, VaR estimates from two independent sources are rarely calculated in the same way. Without a thorough understanding of how each VaR model was calculated, it would be difficult to compare two different VaR calculations from different sources. The level of confidence is 95%. The time across which these possible value changes are being estimated is through the end of the next business day. A closed-form delta-neutral method used throughout the finance and energy sectors is employed to calculate this VaR. VaR is back tested to verify usefulness.

On average, portfolio value should not fall more than VaR on 95 out of 100 business days. Conversely, portfolio value declines of more than VaR should be expected, on average, 5 out of 100 business days. When more value than VaR is lost due to market price changes, VaR is not representative of how much value beyond VaR will be lost.

In February 2009, the Fourth Circuit reversed the District Court. The Fourth Circuit held that the Corps’ jurisdiction under Section 404 of the Clean Water Act is limited to the narrow issue of the filling of jurisdictional waters. The court also held that the Corps’ findings of no significant impact under the National Environmental Policy Act and no significant degradation under the Clean Water Act are entitled to deference. Such findings entitle the Corps to avoid preparing an environmental impact statement, the absence of which was one issue on appeal. These holdings also validated the type of mitigation projects proposed by our operations to minimize impacts and comply with the relevant statutes. Finally, the Fourth Circuit found that stream segments, together with the sediment ponds to which they connect, are unitary “waste treatment systems,” not “waters of the United States,” and that the Corps’ had not exceeded its authority in permitting them.

OVEC sought rehearing before the entire appellate court, which was denied in May, 2009, and the decision was given legal effect in June 2009. An appeal to the U.S. Supreme Court was then filed in August 2009. On August 3, 2010 OVEC withdrew its appeal.

Mingo Logan filed a motion for summary judgment with the district court in July 2009, asking that judgment be entered in its favor because no outstanding legal issues remained for decision as a result of the Fourth Circuit’s February 2009 decision. By a series of motions, the United States obtained extensions and stays of the obligation to respond to the motion in the wake of its letters to the Corps dated September 3 and October 16, 2009 (discussed below). By order dated April 22, 2010, the District Court stayed the case as to Mingo Logan for the shorter of either six months or the completion of the U.S. Environmental Protection Agency’s (the “EPA”) proposed action to deny Mingo Logan the right to use its Corps’ permit (as discussed below). The stay currently remains in effect.

On October 15, 2010, the United States moved to extend the existing stay for an additional 120 days (until February 22, 2011) while the EPA Administrator reviewed the “Recommended Determination” issued by the EPA Region 3. By Memorandum Opinion and Order dated November 2, 2010, the court granted the United States’ motion. On January 13, 2011, the EPA issued its “Final Determination” to withdraw the specification of two of the three watersheds as a disposal site for dredged or fill material approved under the current Section 404 permit. The court has been notified of the Final Determination and by order dated March 21, 2011 stayed further proceedings in the case until further order of the court, in light of the challenge to the EPA’s “Final Determination” currently pending in federal court in Washington, DC. As described more fully below, the federal court in Washington, DC, by Memorandum and Opinion and separate Order, each dated March 23, 2012, granted Mingo Logan’s motion for summary judgment, vacated EPA’s Final Determination and found valid and in full force Mingo Logan’s Section 404 permit. On April 5, 2012, Mingo Logan moved to lift the stay referenced above.

On June 5, 2012, the Court entered an order lifting the stay and allowing the case to proceed on Mingo Logan’s Motion for Summary Judgment. Shortly thereafter, OVEC filed a motion for leave to file a seventh amended and supplemental complaint seeking to update existing counts and raising two new claims (one, to enforce EPA’s “Final Determination” and, the other, that the Corps’ refusal to prepare a Supplemental Environmental Impact Statement violates the APA and NEPA). By Memorandum, Opinion and Order dated July 25, 2012, the Court granted OVEC’s motion and directed the Clerk to file OVEC’s Seventh Amended and Supplemental Complaint.

EPA Actions Related to Water Discharges from the Spruce Permit

By letter of September 3, 2009, the EPA asked the Corps of Engineers to suspend, revoke or modify the existing permit it issued in January 2007 to Mingo Logan under Section 404 of the Clean Water Act, claiming that “new information and circumstances have arisen which justify reconsideration of the permit.” By letter of September 30, 2009, the Corps of Engineers advised the EPA that it would not reconsider its decision to issue the permit. By letter of October 16, 2009, the EPA advised the Corps that it has “reason to believe” that the Mingo Logan mine will have “unacceptable adverse impacts to fish and wildlife resources” and that it intends to issue a public notice of a proposed determination to restrict or prohibit discharges of fill material that already are approved by the Corps’ permit. By federal register publication dated April 2, 2010, the EPA issued its “Proposed Determination to Prohibit, Restrict or Deny the Specification, or the Use for Specification of an Area as a Disposal Site: Spruce No. 1 Surface Mine, Logan County, WV” pursuant to Section 404(c) of the Clean Water Act, the EPA accepted written comments on its proposed action (sometimes known as a “veto proceeding”), through June 4, 2010 and conducted a public hearing, as well, on May 18, 2010. We submitted comments on the action during this period. On September 24, 2010, the EPA Region 3 issued a “Recommended Determination” to the EPA Administrator recommending that the EPA prohibit the placement of fill material in two of the three watersheds for which filling is approved under the current Section 404 permit. Mingo Logan, along with the Corps, West Virginia DEP and the mineral owner, engaged in a consultation with the EPA as required by the regulations, to discuss “corrective action” to address the “unacceptable adverse effects” identified. On January 13, 2011, the EPA issued its “Final Determination” pursuant to Section 404(c) of the Clean Water Act to withdraw the specification of two of the three watersheds approved in the current Section 404 permit as a disposal site for dredged or fill material. By separate action, Mingo Logan sued the EPA on April 2, 2010 in federal court in Washington, D.C. seeking a ruling that the EPA has no authority under the Clean Water Act to veto a previously issued permit (Mingo Logan Coal Company, Inc. v. USEPA, No. 1:10-cv-00541(D.D.C.)). The EPA moved to dismiss that action, and we responded to that motion.

Pursuant to a scheduling order for summary disposition of the case, motions and cross-motions for summary judgment by both parties were filed. On November 30, 2011, the court heard arguments from the parties limited only to the threshold issue of whether the EPA had the authority under Section 404(c) of the Clean Water Act to withdraw the specification of the disposal site after the Corps had already issued a permit under Section 404(a). The court deferred consideration of the remaining issue (i.e. whether the EPA’s “Final Determination” is otherwise lawful) until after consideration of the threshold issue. On March 23, 2012, the court entered an Order and a Memorandum Opinion granting Mingo Logan’s motion for summary judgment, denying EPA’s cross-motion for summary judgment, vacating the Final Determination and ordering that Mingo Logan’s Section 404 permit remains valid and in full force.

On May 11, 2012, EPA filed a notice of appeal to the United States Court of Appeals for the District of Columbia Circuit. The Court entered a briefing schedule and the matter is pending the parties’ briefs.

Allegheny Energy Contract Matter

Allegheny Energy Supply (“Allegheny”), the sole customer of coal produced at our subsidiary Wolf Run Mining Company’s (“Wolf Run”) Sycamore No. 2 mine, filed a lawsuit against Wolf Run, Hunter Ridge Holdings, Inc. (“Hunter Ridge”), and ICG in state court in Allegheny County, Pennsylvania on December 28, 2006, and amended its complaint on April 23, 2007. Allegheny claimed that Wolf Run breached a coal supply contract when it declared force majeure under the contract upon idling the Sycamore No. 2 mine in the third quarter of 2006, and that Wolf Run continued to breach the contract by failing to ship in volumes referenced in the contract. The Sycamore No. 2 mine was idled after encountering adverse geologic conditions and abandoned gas wells that were previously unidentified and unmapped.

After extensive searching for gas wells and rehabilitation of the mine, it was re-opened in 2007, but with notice to Allegheny that it would necessarily operate at reduced volumes in order to safely and effectively avoid the many gas wells within the reserve. The amended complaint also alleged that the production stoppages constitute a breach of the guarantee agreement by Hunter Ridge and breach of certain representations made upon entering into the contract in early 2005. Allegheny voluntarily dropped the breach of representation claims later. Allegheny claimed that it would incur costs in excess of $100 million to purchase replacement coal over the life of the contract. ICG, Wolf Run and Hunter Ridge answered the amended complaint on August 13, 2007, disputing all of the remaining claims.

At the trial, Allegheny presented its evidence for breach of contract and claimed that it is entitled to past and future damages in the aggregate of between $228 million and $377 million. Wolf Run and Hunter Ridge presented their defense of the claims, including evidence with respect to the existence of force majeure conditions and excuse under the contract and applicable law. Wolf Run and Hunter Ridge presented evidence that Allegheny’s damages calculations were significantly inflated because it did not seek to determine damages as of the time of the breach and in some instances artificially assumed future nondelivery or did not take into account the apparent requirement to supply coal in the future. On May 2, 2011, the trial court entered a Memorandum and Verdict determining that Wolf Run had breached the coal supply contract and that the performance shortfall was not excused by force majeure. The trial court awarded total damages and interest in the amount of $104.1 million. ICG and Allegheny filed post-verdict motions in the trial court and on August 23, 2011, the court denied the parties’ motions. The court entered a final judgment on August 25, 2011, in the amount of $104.1 million, which included pre-judgment interest. The parties appealed the lower court’s decision to the Superior Court of Pennsylvania. Wolf Run and Hunter Ridge have filed an appeal bond in the amount of $124.9 million. Briefing is complete and oral argument was held on May 16, 2012. The matter is pending a decision by the Court.

Saratoga Class Action Matter

On January 7, 2008, Saratoga Advantage Trust (“Saratoga”) filed a class action lawsuit in the U.S. District Court for the Southern District of West Virginia against ICG and certain of its officers and directors seeking unspecified damages. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder, based on alleged false and misleading statements in the registration statements filed in connection with ICG’s November 2005 reorganization and December 2005 public offering of common stock. In addition, the complaint challenges other of ICG’s public statements regarding its operating condition and safety record. On July 6, 2009, Saratoga filed an amended complaint asserting

Table of Contents

essentially the same claims but seeking to add an individual co-plaintiff. ICG has filed a motion to dismiss the amended complaint. In June 2011, ICG agreed to settle this matter for a total of $1.375 million. On August 1, 2011, the court issued its order preliminarily approving settlement and conducted a settlement fairness hearing on November 14, 2011. The matter is pending Court approval.

ICG Hazard

The Sierra Club, on December 3, 2010, filed a Notice of Intent (“NOI”) to sue ICG Hazard, LLC (“Hazard”) alleging violations of the Clean Water Act and the Surface Mining Control and Reclamation Act of 1977 at Hazard’s Thunder Ridge surface mine. The NOI, which was supplemented by a revised filing on February 24, 2011, claims that Hazard is discharging selenium and contributing to conductivity levels in the receiving streams in violation of state and federal regulations. On May 24, 2011, the Sierra Club sued Hazard in U.S. District Court for the Eastern District of Kentucky under the Citizens Suit provisions of the Clean Water Act and the Surface Mining Control and Reclamation Act seeking civil penalties, injunctive relief and attorneys’ fees. On February 17, 2012, ICG Hazard filed a motion for summary judgment. Also on February 17, 2012, the Sierra Club filed a competing motion for summary judgment. The matter is pending before the Court.

Kentucky Energy and Environment Cabinet

On December 3, 2010, the Kentucky Energy and Environment Cabinet (“Cabinet”) filed suit against Hazard, ICG Knott County, LLC, ICG East Kentucky, LLC and Powell Mountain Energy, LLC (collectively, “KY Operations”) alleging that the KY Operations failed to comply with the terms and conditions of the Kentucky Pollutant Discharge Elimination System (“KPDES”) permits issued by the Cabinet’s Division of Water to the KY Operations. Among the claims lodged by the Cabinet were allegations that contract water monitoring laboratories retained by the KY Operations did not adhere to the practices and procedures required for conducting KPDES monitoring, the contract laboratories failed to properly document and maintain records of the monitoring and the KY Operations submitted quarterly Discharge Monitoring Reports that sometimes contained inaccurate, incomplete and erroneous information. The KY Operations and the Cabinet entered a proposed Consent Judgment contemporaneously with the filing of the complaint that, if approved by the Franklin County (KY) Circuit Court, will require the KY Operations to pay a monetary penalty of $0.4 million, to prepare and implement a Corrective Action Plan that corrects the deficiencies in the respective KPDES monitoring programs, to identify the responsible corporate officers for each KPDES permit and to provide specific detailed information in support of the Discharge Monitoring Reports to be filed for the fourth quarter 2010 and first quarter 2011. Final resolution of this matter is pending approval by the court. On February 11, 2011, the court entered an order allowing certain anti-mining groups to intervene in the action to contest the validity of the Consent Judgment. The hearing on the entry of the Consent Judgment was held beginning August 30, 2011 and the matter is pending a decision from the court.

By letter dated June 28, 2011, Appalachian Voices, Inc., Waterkeeper Alliance, Inc., Kentuckians for the Commonwealth, Inc., Kentucky Riverkeeper, Inc., Ms. Pat Banks, Ms. Lanny Evans, Mr. Thomas H. Bonny, and Mr. Winston Merrill Combs (collectively, “Appalachian Voices”) filed a NOI to sue the KY Operations for alleged violations of the Clean Water Act. The NOI claims that ICG has violated and continues to violate effluent standards or limitations under the Clean Water Act in reference to KPDES Coal General Permit. The NOI also alleges a lack of diligent prosecution related to the lawsuit filed by the Kentucky Energy and Environment Cabinet (as referenced and described above). On October 25, 2011, Appalachian Voices sued the KY Operations in U.S. District Court for the Eastern District of Kentucky under the Citizens Suit provisions of the Clean Water Act seeking civil penalties, injunctive relief and attorneys’ fees.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

In September 2006, our board of directors authorized a share repurchase program for the purchase of up to 14,000,000 shares of our common stock. There is no expiration date on the current authorization, and we have not made any decisions to suspend or cancel purchases under the program. As of June 30, 2012, there were 10,925,800 shares of our common stock available for purchase under this program. We did not purchase any shares of our common stock under this program during the quarter ended June 30, 2012. Based on the closing price of our common stock as reported on the New York Stock Exchange on July 31, 2012, the approximate dollar value of our common stock that may yet be purchased under this program was $78.8 million.
