RISK FACTORS

Investing in our common stock involves substantial risks. You should carefully consider each of the following risks and all of the other information set forth in this prospectus before making an investment decision regarding our common stock. In addition, past financial performance may not be a reliable indicator of future performance and historical trends should not be used to anticipate results or trends in future periods. If any of the following risks and uncertainties develops into actual events, our business, financial condition or results of operations could be materially and adversely affected. In that case, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to Our Operations

Unfavorable economic conditions may cause our customers to reduce their demand for our products or default on their obligations to us, both of which could adversely affect our cash flows, financial position or results of operations.

Economic conditions in the United States and throughout much of the world experienced a sudden, sharp downturn in 2008 and 2009. If such unfavorable economic conditions were to occur again, certain of our metallurgical coke customers may reduce their demand for our coke and coal, seek to delay shipments, or may struggle or fail to meet their obligations to us, especially if they experience defaults on receivables due from their customers. Our steel industry customers experience significant fluctuations in demand for steel products because of economic conditions, consumer demand, raw material and energy costs, and decisions by the U.S. federal and state governments to fund or not fund infrastructure projects, such as highways, bridges, schools, energy plants, railroads and transportation facilities. Unfavorable economic conditions, including the reduced availability of credit, may cause a reduction in the demand for steel products, which, in turn, could adversely affect our customers’ demand for our products. During periods of weak demand for steel or coal, our customers may seek to renegotiate or cancel their existing coke and coal purchase commitments to us, or decline to renew existing agreements with us when such agreements expire. As a result, we may not be able to sell all the coke and coal that we produce.

Future disruptions of the credit markets may result in financial instability of some of our customers and, in some cases, lead to their insolvency and/or bankruptcy. Such instability could cause our customers to default on their obligations to us. In addition, competition with other suppliers of coke or coal could force us to extend credit to customers and on terms that could increase the risk of payment default. Any of these events ultimately could have an adverse effect on our cash flows, financial position or results of operations.

We are subject to extensive laws and regulations, which may increase our cost of doing business and have an adverse effect on our cash flows, financial position or results of operations.

Environmental, Health and Safety Laws

Our operations are subject to increasingly strict regulation by federal, state and local authorities with respect to protection of the environment and health and safety matters, including those legal requirements pursuant to the Clean Air Act and other laws that govern discharges of substances into the air and water, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites, the protection of groundwater quality and availability, plant and wildlife protection, reclamation and restoration of properties after mining or drilling is completed, the installation of various safety equipment in our facilities, control of surface subsidence from underground mining protection of employee health and safety. Complying with these requirements, including the terms of our permits, can be costly and time-consuming, and may delay commencement or continuation of exploration or production operations.

Failure to comply with these regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of cleanup and site restoration costs and liens, the issuance of injunctions to limit or cease operations, the suspension or revocation of permits and other enforcement measures that could limit our

operations. We may not have been, or may not be, at all times, in complete compliance with all of these requirements, and we may incur material costs or liabilities in connection with these requirements, or in connection with remediation at sites we own, or third-party sites where it has been alleged that we have liability, in excess of the amounts we have accrued. In addition, these requirements are complex, change frequently and have tended to become more stringent over time. These requirements may change in the future in a manner that could have a material adverse effect on our business. For a description of certain environmental laws and matters applicable to us, see “Business—Legal and Regulatory Requirements.”

In addition, greenhouse gas emissions may be subject to future federal regulation. The EPA has begun to implement greenhouse gas-related reporting and permitting rules, and the U.S. Congress has considered “cap and trade” legislation that would establish an economy-wide cap on emissions of greenhouse gases and require most sources of greenhouse gas emissions to obtain greenhouse gas emission “allowances” corresponding to their annual emissions of greenhouse gases. Federal or state regulations requiring us, or our customers, to employ expensive technology to capture and sequester carbon dioxide could adversely affect our future revenues, or profitability.

Healthcare Laws

In March 2010, the Patient Protection and Affordable Care Act, or PPACA, was enacted, potentially affecting our costs to provide healthcare benefits to our eligible active and retired employees and certain black lung benefits. The PPACA has both short-term and long-term implications on benefit plan standards. Implementation of this legislation is planned to occur in phases, with plan standard changes taking effect beginning in 2010, but to a greater extent with the 2011 benefit plan year and extending through 2018. In the short term, our healthcare costs may rise, due to an increase in the maximum age for covered dependents to receive benefits, changes to benefits for occupational disease related illnesses, the elimination of lifetime dollar limits per covered individual and restrictions of annual dollar limits per covered individual, among other standard requirements. In the long term, our healthcare costs could increase due to a tax on “high cost” plans and the elimination of annual dollar limits per covered individual, among other standard requirements. Changes that make it easier to qualify for black lung benefits also may result in increased costs. We currently are analyzing this legislation to determine the full extent of the impact of the required changes to comply with this legislation and the resulting costs. A substantial increase in costs as a result of this legislation, and the related regulations, could have a potentially adverse effect on our financial condition or results of operations.

Equipment upgrades, equipment failures and deterioration of assets may lead to production curtailments, shutdowns or additional expenditures.

Our cokemaking and coal mining operations depend upon critical pieces of equipment that occasionally may be out of service for scheduled upgrades or maintenance or as a result of unanticipated failures. Our facilities are subject to equipment failures and the risk of catastrophic loss due to unanticipated events such as fires, accidents or violent weather conditions. As a result, we may experience interruptions in our processing and production capabilities, which could have a material adverse effect on our results of operations and financial condition.

In addition, assets critical to the operations of our cokemaking and coal mining operations, including our cokemaking facilities and equipment and our coal mines, may deteriorate or become depleted materially sooner than we currently estimate. Such deterioration of assets may result in additional maintenance spending or additional capital expenditures. If these assets do not generate the amount of future cash flows that we expect, and we are not able to procure replacement assets in an economically feasible manner, our future results of operations may be materially and adversely affected.

We are also required to perform impairment tests on our assets whenever events or changes in circumstances lead to a reduction of the estimated useful life or estimated future cash flows that would indicate that the carrying amount may not be recoverable or whenever management’s plans change with respect to those assets. For example, at our Indiana Harbor cokemaking facility some ovens and associated equipment are

heaving and settling differentially as a result of the instability of the ground on which it was constructed. This differential movement has reduced production and required corrective action to certain ovens, ancillary equipment and structures. A preliminary engineering assessment has determined that a total investment of approximately $50 to $100 million may be required in the 2011 through 2013 timeframe to refurbish the facility. The majority of the spending to complete this refurbishment will take place in 2012 and 2013 and will be contingent on reaching commercially agreeable terms for a long-term contract extension with our customer and the third-party investors in the Indiana Harbor operations. In the interim, an oven repair and maintenance program that is consistent with the refurbishment program and that limits further deterioration of the ovens has been implemented. Higher maintenance costs are forecasted to continue until the refurbishment program is completed. If we are required to incur impairment charges in the future, our results of operations in the period taken could be materially and adversely affected.

We may be unable to obtain, maintain or renew permits or leases necessary for our operations, which could materially reduce our production, cash flow or profitability.

Our cokemaking facilities and coal mining operations require us to obtain a number of permits that impose strict regulations on various environmental and operational matters in connection with cokemaking and coal mining. These include permits used by various federal, state and local agencies and regulatory bodies. The permitting rules, and the interpretations of these rules, are complex, change frequently, and are often subject to discretionary interpretations by our regulators, all of which may make compliance more difficult or impractical, and may possibly preclude the continuance of ongoing operations or the development of future cokemaking facilities or coal mines. The public, including non-governmental organizations, environmental groups and individuals, have certain statutory rights to comment upon and submit objections to requested permits and environmental impact statements prepared in connection with applicable regulatory processes, and otherwise engage in the permitting process, including bringing citizen’s lawsuits to challenge the issuance of permits, the validity of environmental impact statements or performance of cokemaking or coal mining activities. For example, environmental groups have challenged our permit-to-install, or PTI, for our Middletown, Ohio facility on the basis that the facility fails to satisfactorily meet the requirements of the Clean Air Act. If this challenge succeeds, or any permits or leases are not issued or renewed in a timely fashion or at all, or if permits issued or renewed are conditioned in a manner that restricts our ability to efficiently and economically conduct our cokemaking or coal mining operations, our cash flows or profitability could be materially and adversely affected.

Our businesses are subject to inherent risks, some for which we maintain third-party insurance and some for which we self-insure. We may incur losses and be subject to liability claims that could have a material adverse effect on our financial condition, results of operations or cash flows.

We currently maintain insurance policies through Sunoco that provide limited coverage for some, but not all, of the potential risks and liabilities associated with our businesses. For some risks, we may not obtain insurance if we believe the cost of available insurance is excessive relative to the risks presented. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially, and in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. As a result, we may not be able to renew our existing insurance policies or procure other desirable insurance on commercially reasonable terms, if at all. In addition, certain environmental and pollution risks generally are not fully insurable. Even where insurance coverage applies, insurers may contest their obligations to make payments. Our insurance costs may increase and certain coverages may be unavailable if we are no longer participating in Sunoco’s insurance plans or programs. Our financial condition, results of operations and cash flows could be materially and adversely affected by losses and liabilities from un-insured or under-insured events, as well as by delays in the payment of insurance proceeds, or the failure by insurers to make payments.

We also may incur costs and liabilities resulting from claims for damages to property or injury to persons arising from our operations. We must compensate employees for work-related injuries. If we do not make adequate provision for our workers’ compensation liabilities, it could harm our future operating results. If we are pursued for these sanctions, costs and liabilities, our operations and our profitability could be adversely affected.

Our operating results have been and may continue to be affected by fluctuations in our costs of production, and, if we cannot pass increases in our costs of production to our customers, our financial condition, results of operations and cash flows may be negatively affected.

Over the course of the last two to three years, many of the components of our cost of produced coke and coal revenues, including cost of supplies, equipment and labor, have experienced significant price inflation, and such price inflation may continue in the future. Our coal mining operations, for example, require a reliable supply of mining and industrial equipment, replacement parts, fuel and steel-related products, including roof control and lubricants. The supplier base providing such mining materials and equipment has been relatively consistent in recent years, although there continues to be consolidation, resulting in a situation where purchases of certain underground mining equipment are concentrated in single suppliers. The price of such components is also highly volatile. Our profit margins may be reduced and our financial condition, results of operations and cash flows may be adversely affected if the costs of production increase significantly and we cannot pass such increases in our costs of production to our customers.

If we fail to maintain satisfactory labor relations, we may be adversely affected. Union represented labor creates an increased risk of work stoppages and higher labor costs.

If some, or all, of our non-union operations become unionized, we may be subject to an increased risk of work stoppages, other labor disputes and higher labor costs, which may adversely affect the stability of production and reduce our future revenues, or profitability. Legislation has been proposed to the U.S. Congress to enact a law allowing for workers to choose union representation solely by signing election cards, which would eliminate the use of secret ballots to elect union representation. While the impact is uncertain, if such legislation is enacted into law, it will be administratively easier for labor unions to organize into collective bargaining units and may lead to more of our operations becoming unionized.

We have obligations for long-term employee plan benefits that may involve expenses that are greater than we have assumed.

We are required to provide various long-term employee benefits to retired employees and current employees who will retire in the future. At December 31, 2010, these obligations included:

We have estimated certain of these unfunded obligations based on actuarial assumptions described in the notes to our financial statements. However, if our assumptions are inaccurate, we could be required to expend materially greater amounts than anticipated. Approximately 98 percent of the pension benefits were funded on an accounting basis at December 31, 2010, while the post-retirement medical and life insurance obligations are unfunded. If we are required to expend materially greater amounts than anticipated, it could have a material and adverse effect on our financial condition, results of operations and cash flows.

We currently are, and likely will be, subject to litigation, the disposition of which could have a material adverse effect on our cash flows, financial position or results of operations.

The nature of our operations exposes us to possible litigation claims in the future, including disputes relating to our operations and commercial and contractual arrangements. Although we make every effort to avoid litigation, these matters are not totally within our control. We will contest these matters vigorously and have made insurance claims where appropriate, but because of the uncertain nature of litigation and coverage decisions, we cannot predict the outcome of these matters. We recently settled a significant litigation matter with certain operating subsidiaries of ArcelorMittal USA, the customer purchasing coke from our Jewell cokemaking facility. Litigation is very costly, and the costs associated with prosecuting and defending litigation matters could

19

Table of Contents

have a material adverse effect on our financial condition and profitability. In addition, our profitability or cash flow in a particular period could be affected by an adverse ruling in any litigation currently pending in the courts or by litigation that may be filed against us in the future. We are also subject to significant environmental and other government regulation, which sometimes results in various administrative proceedings.

Risks Related to Our Cokemaking Business

Our customers operate in a competitive and cyclical industry, and their default or non-compliance on their contractual obligations to purchase coke from us, or the failure of our customers to continue to purchase coke from us at similar prices under similar arrangements, may have a material and adverse effect on our financial position, results of operations and cash flows.

All of our coke sales agreements currently contain take-or-pay provisions, pursuant to which our customers are required to either take all of our coke production up to a specified tonnage maximum or pay the contract price for any such coke they elect not to accept. During periods of weak demand for steel, our steel industry customers may experience significant reductions in their operations, or substantial declines in the prices of the steel they sell. These and other factors may lead some customers to seek renegotiation or cancellation of their existing long-term coke purchase commitments to us. We have, and will continue to, work constructively with our customers to resolve issues, and, where appropriate, we will actively pursue legal process to protect our rights. Customer defaults on existing contractual obligations to purchase our coke may have a material and adverse effect on our financial position, results of operations and cash flows.

If a substantial portion of our agreements to supply metallurgical coke are modified or terminated or if force majeure is exercised, we may be adversely affected if we are not able to replace such agreements, or if we are not able to enter into new agreements at the same level of profitability. The profitability of our long-term coke sales agreements depends on a variety of factors that vary from agreement to agreement and fluctuate during the agreement term. We may not be able to obtain long-term agreements at favorable prices, compared either to market conditions or to our cost structure. Price changes provided in long-term supply agreements may not reflect actual increases in production costs. As a result, such cost increases may reduce profit margins on our long-term coke sales agreements. In addition, contractual provisions for adjustment or renegotiation of prices and other provisions may increase our exposure to short-term price volatility.

From time to time, we discuss the extension of existing agreements and enter into new long-term agreements for the supply of metallurgical coke to our customers, but these negotiations may not be successful and these customers may not continue to purchase coke from us under long-term coke sales agreements. If any one or more of these customers were to significantly reduce their purchases of coke from us, or if we were unable to sell coke to them on terms as favorable to us as the terms under our current agreements, our cash flows, financial position and results of operations may be materially and adversely affected.

Further, because of certain technological design constraints, which are discussed in more detail in “Business—Our Cokemaking Technology,” we do not have the ability to shut down our cokemaking operations if we do not have adequate customer demand. If a customer refuses to take or pay for our coke, we must continuously operate our coke ovens even though we may not be able to sell our coke immediately and may incur significant additional costs for natural gas to maintain the temperature inside our coke oven batteries, which may have a material and adverse effect on our financial position, results of operations and cash flows.

The financial performance of our cokemaking business is substantially dependent upon three customers in the steel industry, and any failure by them to perform under their contracts with us could adversely affect our financial condition, results of operations and cash flows.

Substantially all of our domestic coke sales are currently made under long-term contracts with ArcelorMittal, U.S. Steel and AK Steel. For the year ended December 31, 2010, ArcelorMittal accounted for approximately 69 percent of our total revenues. We expect these three customers to continue to account for a

20

Table of Contents

significant portion of our revenues for the foreseeable future. If any one or more of these customers were to significantly reduce its purchases of coke from us, or default on their agreements with us, or fail to renew or terminate its agreements with us, or if we were unable to sell coke to any one or more of these customers on terms as favorable to us as the terms under our current agreements, our cash flows, financial position and results of operations could be materially and adversely affected.

We may not be able to successfully implement our North American growth strategy and develop, design, construct, start up, or operate new cokemaking facilities in North America.

We may not be able to complete construction of, or efficiently operate, cokemaking facilities that we develop in the future, including our Middletown, Ohio cokemaking facility, which is currently under construction. Further development of future cokemaking facilities may not be within the expected time line or budget. We cannot predict the effect that any failed expansion may have on our core business. Regardless of whether we are successful in constructing and/or operating additional cokemaking facilities, the negotiations for development of such facilities could disrupt our ongoing business, distract management and increase our expenses. If we are not able to successfully execute our plans for the development and expansion of our North American cokemaking operations, whether as a result of unfavorable market conditions in the steel industry or otherwise, our future revenues and profitability could be materially and adversely affected.

We may not be able to successfully implement our international growth strategy and develop, design, construct, start up and operate new cokemaking facilities outside of North America.

A central element of our growth strategy involves the international expansion of our business. We expanded our cokemaking business internationally in 2007 through our development and operation of our customer’s cokemaking facility in Vitória, Brazil. We are currently exploring opportunities with steel companies for developing new cokemaking facilities in foreign countries, which could be either wholly owned or developed through other business structures.

Our ability to expand internationally and enter into additional arrangements in non-U.S. markets is subject to a variety of risks, including, but not limited to:

If we are not able to successfully execute our plans for international development and expansion of our cokemaking operations, as a result of unfavorable market conditions in the steel industry or otherwise, our future revenues and profitability could be materially and adversely affected.

Excess capacity in the global steel industry, including in China, may weaken demand for steel produced by our U.S. steel industry customers, which, in turn, may reduce demand for our coke.

In some countries, such as China, steelmaking capacity exceeds demand for steel products. Rather than reducing employment by matching production capacity to consumption, steel manufacturers in these countries (often with local government assistance or subsidies in various forms) may export steel at prices that are significantly below their home market prices and that may not reflect their costs of production or capital. The availability of this steel at such prices may negatively affect our steelmaking customers, who may not be able to increase the prices that they charge for steel as supply of steel increases. As a result, the profitability and financial position of our steelmaking customers may be adversely affected, which in turn, could adversely affect the certainty of our long-term relationships with those customers and our own financial position, results of operations and cash flows.

We face increasing competition both from alternative steelmaking and cokemaking technologies that have the potential to reduce or completely eliminate the use of metallurgical coke, may reduce the demand for the coke we produce and which could have an adverse effect on our results of operations.

Historically, metallurgical coke has been used as a main input in the production of steel in blast furnaces, and nearly all integrated steel mills still use blast furnace technology. However, many steelmakers also are exploring alternatives to blast furnace technology that require less or no use of metallurgical coke. For example EAF technology is a commercially proven process widely used in the United States. As these alternative processes for production of steel become more widespread, the demand for metallurgical coke, including the coke we produce, may be significantly reduced, and this reduction could have a material and adverse effect on our financial position, results of operations and cash flows.

We also face competition from alternative cokemaking technologies, including both by-product and non-recovery technologies. As these technologies improve and as new technologies are developed, we anticipate that competition among non-conventional coke producers will intensify. Such increased competition may adversely affect our future revenues and profitability.

Certain provisions in our long-term coke sales agreements, resulting in suspension of the performance due to force majeure, or imposition of economic penalties for failure to meet minimum volume requirements or other required specifications, may have an adverse effect on our future revenues, or profitability.

All of our coke sales agreements contain provisions requiring us to supply minimum volumes of coke to our customers. To the extent we do not meet these minimum volumes, we are generally required under the terms of our coke sales agreements to procure replacement coke supply to our customers at the applicable contract price or potentially be subject to cover damages for any shortfall. For example, in 2010, we did not meet our contractual volume minimums at our Indiana Harbor cokemaking facility. Because our customer did not require the additional coke, we were not required to replace the shortfall nor did we incur financial penalties. In 2011, we again expect production volumes at our Indiana Harbor cokemaking facility to be below the contractual minimum levels and as such, have contracted for third party coke supply to meet the expected shortfall for 2011 at a cost that will exceed our contract selling price. Additionally, production volumes in 2012 and 2013 may also be below the contractual minimums. If future shortfalls occur, we will work with our customer to identify possible other supply sources while we implement operating improvements at this facility, but we may not be successful in identifying alternative supplies and may be subject to paying the contract price for any shortfall or for cover damages, either of which could adversely affect our future revenues and profitability. Most of our coke sales agreements also contain provisions requiring us to deliver coke that meet certain quality thresholds. Failure to meet these specifications could result in economic penalties, including price adjustments, the rejection of deliveries or termination of our agreements, any or all of which could adversely affect our future revenues and profitability.

Our coke sales agreements contain force majeure provisions allowing temporary suspension of performance by our customers during the duration of specified events beyond the control of our customers. Declaration of

22

Table of Contents

force majeure , coupled with a lengthy suspension of performance under one or more coke sales agreements, may seriously and adversely affect our cash flows, financial position and results of operations.

Income from operation of the Vitória, Brazil cokemaking facility may be affected by global and regional economic and political factors and the policies and actions of the Brazilian government.

The Vitória cokemaking facility is owned by a project company controlled by a Brazilian affiliate of ArcelorMittal. We earn income from the Vitória, Brazil operations through licensing and operating fees earned at the Brazilian cokemaking facility payable to us under long-term agreements with the project company and an annual preferred dividend from the project company guaranteed by the Brazilian affiliate of ArcelorMittal. These revenues depend on continuing operations and, in some cases, certain minimum production levels being achieved at the Vitória cokemaking facility. In the past, the Brazilian economy was characterized by frequent and occasionally extensive intervention by the Brazilian government and unstable economic cycles. The Brazilian government has changed in the past, and may change monetary, taxation, credit, tariff and other policies to influence Brazil’s economy in the future. If the operations at Vitória cokemaking facility are interrupted or if certain minimum production levels are not achieved, we will not be able to earn the same licensing and operating fees as we are currently earning which could have an adverse affect on our financial position, results of operations and cash flows.

To the extent we do not meet coal-to-coke yield standards in our coke sales agreements, we are responsible for the cost of the excess coal used in the cokemaking process, which could adversely impact our results of operations and profitability.

Our ability to pass through our coal costs to our customers under our coke sales agreements is generally subject to our ability to meet some form of coal-to-coke yield standard. To the extent that we do not meet the yield standard in the contract, we are responsible for the cost of the excess coal used in the cokemaking process. We may not be able to meet the yield standards at all times, and as a result we may suffer lower margins on our coke sales and our results of operations and profitability could be adversely affected.

Disruptions to our supply of coal and coal blending services may reduce the amount of coke we produce and deliver and, if we are not able to cover the shortfall in coal supply or obtain replacement blending services from other providers, our results of operations and profitability could be adversely affected.

Most of the metallurgical coal used to produce coke at our cokemaking facilities, other than our Jewell facility, is purchased from third parties under one- to two-year contracts. While we believe there is an ample supply of metallurgical coal available and we have been able to supply these facilities without any significant disruption in coke production in the past, economic, environmental, and other conditions outside of our control may reduce our ability to source sufficient amounts of coal for our forecasted operational needs. The failure of our coal suppliers to meet their supply commitments could materially and adversely impact our results of operations if we are not able to make up the shortfalls resulting from such supply failures through purchases of coal from other sources.

Other than at our Jewell cokemaking facility, we rely on third parties to blend coals that we have purchased into coal blends that we use to produce coke. We have entered into long-term agreements with coal blending service providers that are co-terminous with our coke sales agreements. Generally, we store an inventory of blended coal at or near our cokemaking facilities to cover approximately 15 to 30 days of coke production. There are limited alternative providers of coal blending services and disruptions from our current service providers could materially and adversely impact our results of operations.

Limitations on the availability and reliability of transportation, and increases in transportation costs, particularly rail systems, could materially and adversely affect our ability to obtain a supply of coal and deliver coke to our customers.

Our ability to obtain coal depends primarily on third-party rail systems and to a lesser extent river barges. If we are unable to obtain rail or other transportation services, or are unable to do so on a cost-effective basis, our

23

Table of Contents

results of operations could be adversely affected. Alternative transportation and delivery systems are generally inadequate and not suitable to handle the quantity of our shipments or to ensure timely delivery. The loss of access to rail capacity could create temporary disruption until the access is restored, significantly impairing our ability to receive coal and resulting in materially decreased revenues. Our ability to open new cokemaking facilities may also be affected by the availability and cost of rail or other transportation systems available for servicing these facilities.

Our coke production obligations at our Jewell cokemaking facility and one half of our Haverhill cokemaking facility require us to deliver coke to certain customers via railcar. We have entered into long-term rail transportation agreements to meet these obligations. Disruption of these transportation services because of weather-related problems, mechanical difficulties, train derailments, infrastructure damage, strikes, lock-outs, lack of fuel or maintenance items, fuel costs, transportation delays, accidents, terrorism, domestic catastrophe or other events could temporarily or over the long term impair our ability to produce coke, and therefore, could materially and adversely affect our business and results of operations.

The Brazilian licensing agreement for certain of our Brazilian patents used at the Vitória cokemaking facility may terminate if we are not able to maintain or supplement the patents subject to the licensing agreement, which may have an adverse effect on our future revenues and profitability.

We currently collect certain fees in connection with the licensing of certain of our Brazilian patents at the Vitória cokemaking facility pursuant to a Brazilian licensing agreement with a term that runs through 2023. The validity of these patents is being challenged in Brazil, and the patents will otherwise expire by May 2014. We have two patent applications (one of which has been opposed by the party challenging our existing Brazilian patents) awaiting examination that, if approved, we expect will permit the Brazilian licensing agreement to continue through at least 2023. If the challenge to our existing Brazilian patents is successful, or if such Brazilian patents expire prior to a new Brazilian patent becoming subject to the Brazilian licensing agreement, and we no longer have any technology licensed under any applicable licensing agreement, we will no longer receive any licensing fees. The loss of these licensing fees would adversely affect our results of operations.

Labor disputes with the unionized portion of our workforce could affect us adversely.

As of April 30, 2011, we have approximately 980 employees in the United States. Approximately 320, or 33 percent, of our domestic employees, principally at our cokemaking operations, are currently represented by the United Steelworkers under various contracts. As of April 30, 2011, we have approximately 200 employees at the cokemaking facility in Vitória, Brazil all of whom are represented by a union. When these agreements expire or terminate, we may not be able to negotiate the agreements on the same or more favorable terms as the current agreements, or at all, and without production interruptions, including labor stoppages. A prolonged labor dispute, which could include a work stoppage, could adversely affect our ability to satisfy our customers’ orders and, as a result, adversely affect our production and profitability.

Risks Related to Our Coal Mining Business

Coal prices are volatile, and a substantial or extended decline in prices could adversely affect our profitability and the value of our coal reserves.

Our profitability and the value of our coal reserves depend upon the prices we receive for our coal. The contract prices we may receive for coal in the future depend upon factors beyond our control, including:

24

Table of Contents

A substantial or extended decline in the prices we receive for our future coal sales could adversely affect our profitability and the value of our coal reserves.

Extensive governmental regulations pertaining to employee health and safety and mandated benefits for retired coal miners impose significant costs on our mining operations, which could materially and adversely affect our results of operations.

The coal mining industry is subject to increasingly strict regulation by federal, state and local authorities with respect to matters such as employee health and safety and mandated benefits for retired coal miners. Compliance with these requirements imposes significant costs on us and can result in reduced productivity. Moreover, the possibility exists that new health and safety legislation and/or regulations and orders may be adopted that may materially and adversely affect our mining operations. We must compensate employees for work-related injuries. If we do not make adequate provisions for our workers’ compensation liabilities, it could harm our future operating results. In addition, the erosion through tort liability of the protections we are currently provided by workers’ compensation laws could increase our liability for work-related injuries and materially and adversely affect our operating results.

Under federal law, each coal mine operator must secure payment of federal black lung benefits to claimants who are current and former employees and contribute to a trust fund for the payment of benefits and medical expenses to claimants who last worked in the coal industry before January 1, 1970. The trust fund is funded by an excise tax on coal production. If this tax increases, or if we could no longer pass it on to the purchasers of our coal under our coal sales agreements, our operating costs could be increased and our results could be materially and adversely harmed. At December 31, 2010, our liabilities for coal workers’ black lung benefits totaled $26.6 million. If new laws or regulations increase the number and award size of claims, it could materially and adversely harm our business. See “Business—Legal and Regulatory Requirements—Other Regulatory Requirements.”

Federal or state regulatory agencies have the authority to order our mines to be temporarily or permanently closed under certain circumstances, which could materially and adversely affect our ability to meet our customers’ demands.

Federal or state regulatory agencies have the authority under certain circumstances following significant health and safety incidents, such as fatalities, to order a mine to be temporarily or permanently closed. If this occurred, we may be required to incur capital expenditures to re-open the mine and may incur fines. In the event that these agencies order the closing of our mines, our coal sales contracts generally permit us to issue force majeure notices which suspend our obligations to deliver coal under these contracts. However, our customers may challenge our issuances of force majeure notices. If these challenges are successful, we may have to purchase coal from third-party sources, if it is available, to fulfill these obligations, incur capital expenditures to re-open the mines and/or negotiate settlements with the customers, which may include price reductions, the reduction of commitments or the extension of time for delivery or terminate customers’ contracts. Our coal operations also provide substantially all of the coal used at our Jewell cokemaking facility. The inability to deliver the required coal to this facility could significantly impact operations at the facility. Any of these actions could have a material adverse effect on our business and results of operations.

25

Extensive environmental regulations impose significant costs on our mining operations, and future regulations could materially increase those costs, impose new or increased liabilities, limit our ability to produce and sell coal, or require us to change our operations significantly, any one or more of which could materially and adversely affect our financial position and/or results of operations.

Our coal mining operations are subject to increasingly strict regulation by federal, state and local authorities with respect to environmental matters such as:

The costs, liabilities and requirements associated with the laws and regulations related to these and other environmental matters can be costly and time-consuming, and could delay commencement or continuation of expansion or production operations. We may not have been, or may not be, at all times in compliance with the applicable laws and regulations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of cleanup and site restoration costs and liens, the issuance of injunctions to limit or cease operations, the suspension or revocation of permits and other enforcement measures that could have the effect of limiting production from our operations. We may incur material costs and liabilities resulting from claims for damages to property or injury to persons arising from our operations. If we are pursued for sanctions, costs and liabilities in respect of these matters, our mining operations and, as a result, our profitability could be materially and adversely affected.

New legislation or administrative regulations or new judicial interpretations or administrative enforcement of existing laws and regulations, including proposals related to the protection of the environment that would further regulate and tax the coal industry, also may require us to change operations significantly, or incur increased costs. Such changes could have a material adverse effect on our financial condition and results of operations. You should see the section entitled “Business—Legal and Regulatory Requirements” for further information about the various governmental regulations affecting us.

Our coal mining operations are subject to operating risks, some of which are beyond our control, that could result in a material increase in our operating expenses and a decrease in our production levels.

Factors beyond our control could disrupt our coal mining operations, adversely affect production and shipments and increase our operating costs, all of which could have a material adverse effect on our results of operations. Such factors could include:

If any of these conditions or events occur, our coal mining operations may be disrupted, we could experience a delay or halt of production or shipments, operating costs could increase significantly, and we could incur substantial losses. In particular, our Jewell cokemaking facility currently obtains essentially all of its metallurgical coal requirements from our existing coal mining operations. Disruptions in our coal mining operations, resulting in decreased production of metallurgical coal, could seriously and adversely affect production at our Jewell cokemaking facility.

If transportation for our coal becomes unavailable or uneconomic for our customers, it may impair our ability to sell coal, and our results of operations may be adversely affected.

Transportation costs represent a significant portion of the total cost of coal and the cost of transportation is a critical factor in a customer’s purchasing decision. Increases in transportation costs and the lack of sufficient rail and port capacity could lead to reduced coal sales. For example, all of our coal mining operations are substantially dependent on, and only have access to, a single rail provider. A substantial amount of the metallurgical coal produced from our coal mining operations is used in our adjacent Jewell cokemaking facility. However, future disruption of transportation services (due to weather-related problems, infrastructure damage, strikes, lock-outs, lack of fuel or maintenance items, underperformance of port and rail infrastructure, congestion and balancing systems used to manage vessel queuing and demurrage, transportation delays or other reasons) may temporarily impair our ability to supply coal to other customers and adversely affect our results of operations.

We face numerous uncertainties in estimating economically recoverable coal reserves, and inaccuracies in estimates may result in lower than expected revenues, higher than expected costs and decreased profitability.

Our future performance depends on, among other things, the accuracy of our estimates of our proven and probable coal reserves. There are numerous uncertainties inherent in estimating quantities and values of economically recoverable coal reserves, including many factors beyond our control. As a result, estimates of economically recoverable coal reserves are by their nature uncertain. We base our estimates of reserves on engineering, economic and geological data assembled, analyzed and reviewed by internal and third-party engineers and consultants. We update our estimates of the quantity and quality of proven and probable coal reserves as needed to reflect production of coal from the reserves, updated geological models and mining recovery data, tonnage contained in newly acquired lease areas and estimated costs of production and sale prices.

There are numerous factors and assumptions that affect economically recoverable reserve estimates, including:

Table of Contents

Each of these factors may vary considerably. As a result, estimates of the quantities and qualities of economically recoverable coal attributable to any particular group of properties, classifications of reserves based on risk of recovery, estimated cost of production, and estimates of future net cash flows expected from these properties as prepared by different engineers, or by the same engineers at different times, may vary materially due to changes in the foregoing factors and assumptions. Therefore, our estimates may not accurately reflect our actual reserves. Actual production, revenues and expenditures with respect to reserves will likely vary from estimates, and these variances may be material. In late 2009, we engaged Marshall Miller & Associates, Inc., a leading mining engineering firm, to conduct a new and comprehensive study to determine our proven and probable reserves for our existing coal mines. The firm confirmed that as of December 31, 2010, our proven and probable coal reserves totaled at least 85 million tons. The firm is continuing its work on additional coal seams and is expected to provide us with its evaluation of our proven and probable reserves for those additional seams during the third quarter of 2011. Our acquisition of the HKCC Companies added an additional 21 million tons of proven and probable coal reserves, increasing our total proven and probable reserves to at least 106 million tons. Any inaccuracy in our estimates related to our reserves could result in decreased profitability from lower than expected revenues and/or higher than expected costs.

Our inability to develop coal reserves in an economically feasible manner could materially and adversely affect our business.

Our future success depends upon our ability to continue developing economically recoverable coal reserves. If we fail to develop additional coal reserves, our existing reserves eventually will be depleted. We may not be able to obtain replacement reserves when we require them. Replacement reserves may not be available or, if available, may not be capable of being mined at costs comparable to those characteristic of the depleting mines. Our ability to develop coal reserves in the future also may be limited by the availability of cash we generate from our operations or available financing, restrictions under our existing or future financing arrangements, the lack of suitable opportunities or the inability to acquire coal properties or leases on commercially reasonable terms. If we are unable to develop replacement reserves, our future production may decrease significantly and this may have a material and adverse impact on our cash flows, financial position and results of operations.

Mining in Central Appalachia is more complex and involves more regulatory constraints than mining in other areas of the United States, which could affect our mining operations and cost structures in these areas.

Our coal mines are located in Virginia and West Virginia, in what is known as the Central Appalachian region. The geological characteristics of Central Appalachian coal reserves, such as coal seam thickness, make them complex and costly to mine. As compared to mines in other regions, permitting, licensing and other environmental and regulatory requirements are more costly and time consuming to satisfy. These factors could materially adversely affect the mining operations and cost structures of coal produced at our mines in Central Appalachia.

A defect in title or the loss of a leasehold interest in certain property could limit our ability to mine our coal reserves or result in significant unanticipated costs.

We conduct a significant part of our coal mining operations on properties that we lease. A title defect or the loss of a lease could adversely affect our ability to mine the associated coal reserves. We may not verify title to our leased properties or associated coal reserves until we have committed to developing those properties or coal reserves. In some cases, the seller or lessor warrants property title. In other cases, separate title confirmation may not be required for leasing reserves where mining has occurred previously. Our right to mine some of our reserves may be adversely affected if defects in title or boundaries exist, or if our leasehold interests are subject to superior property rights of third parties. In order to conduct our mining operations on properties where such defects exist, we may incur unanticipated costs. In addition, some leases require us to produce a minimum quantity of coal and require us to pay minimum production royalties. Our inability to satisfy those requirements may cause the leasehold interest to terminate. In addition, we may not be able to successfully negotiate new leases for properties containing additional reserves, or maintain our leasehold interests in properties where we have not commenced mining operations during the term of the lease.

Disruptions in the quantities of coal produced by our contract mine operators could impair our ability to fill customer orders or increase our operating costs.

We use independent contractors to mine coal at certain of our mining operations. Some of our contract miners may experience adverse geologic mining conditions, operational difficulties, escalated costs, financial difficulties, or other factors beyond our control that could affect the availability, pricing, and quality of coal produced for us. In addition, market volatility and price increases for coal or freight could result in non-performance by third-party suppliers under existing contracts with us, in order to take advantage of the higher prices in the current market. Disruptions in the quantities of coal produced by independent contractors for us could impair our ability to supply our cokemaking facilities and to fill our customer orders. Our profitability or exposure to loss on transactions or relationships such as these depends upon the reliability of the supply or the ability to substitute, when economical, third-party coal sources, with internal production or coal purchased in the market and other factors. Non-performance by contract miners may adversely affect our ability to fulfill deliveries under our coal supply agreements. If we are unable to fill a customer order, or if we are required to purchase coal from other sources in order to satisfy a customer order, we could lose existing customers and our operating costs could increase.

We require a skilled workforce to run our coal mining business. If we or our contractors cannot hire qualified people to meet replacement or expansion needs, our labor costs may increase and we may not be able to achieve planned results.

Efficient coal mining using modern techniques and equipment requires skilled workers in multiple disciplines, including experienced foremen, electricians, equipment operators, engineers and welders, among others. Our future success depends greatly on our continued ability to attract and retain highly skilled and qualified personnel. We have an aging workforce, and an extended effort to recruit new employees to replace those who retire or a sustained shortage of skilled labor in the areas in which we operate could make it difficult to meet our staffing needs or result in higher labor rates. We also may be forced to hire novice miners, who are required to be accompanied by experienced workers as a safety precaution. These measures could adversely affect our productivity and operating costs. A lack of qualified people also may affect companies that we use to perform certain specialized work. If we or our contractors cannot find enough qualified workers, it may delay completion of projects and increase our costs.

We have reclamation and mine closure obligations. If the assumptions underlying our accruals are inaccurate, we may be required to expend significantly greater amounts than anticipated.

The Surface Mining Control and Reclamation Act established operational, reclamation and closure standards for all aspects of surface mining as well as most aspects of deep mining. We accrue for the costs of

current mine disturbance and of final mine closure, including the cost of treating mine water discharge where necessary. The amounts recorded are dependent upon a number of variables, including the estimated future retirement costs, estimated proven reserves, assumptions involving profit margins, inflation rates, and the assumed credit-adjusted risk-free interest rates. Furthermore, our reclamation and mine-closing liabilities are unfunded. If these accruals are insufficient, or our cash requirements in a particular year are greater than currently anticipated, our future operating results and cash flows could be adversely affected.

Our failure to obtain or renew surety bonds on acceptable terms could materially and adversely affect our ability to secure reclamation and coal lease obligations and, therefore, our ability to mine or lease coal.

Our reclamation and mine-closing liabilities are unfunded. Federal and state laws require us to obtain surety bonds to secure performance or payment of certain long-term obligations, such as mine closure or reclamation costs, federal and state workers’ compensation costs, coal leases and other obligations. These bonds are typically renewable annually. Surety bond issuers and holders may not continue to renew the bonds or may demand higher fees, additional collateral, including letters of credit or other terms less favorable to us upon those renewals. We are also subject to increases in the amount of surety bonds required by federal and state laws as these laws, or interpretations of these laws, change. Because we are required by state and federal law to have these bonds in place before mining can commence or continue, our failure to maintain (or inability to acquire) these bonds would have a material and adverse impact on us. That failure could result from a variety of factors including the following: lack of availability, higher expense or unfavorable market terms of new bonds; restrictions on availability of collateral for current and future third-party surety bond issuers under the terms of future indebtedness; our inability to meet certain financial tests with respect to a portion of the post-mining reclamation bonds; and the exercise by third-party surety bond issuers of their right to refuse to renew or issue new bonds.
