     CAUTIONARY STATEMENT FOR PURPOSES OF THE SAFE HARBOR PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
     This report contains forward-looking statements within the meaning of the federal securities laws. These statements relate to analyses and other information, which are based on forecasts of future results and estimates of amounts not yet determinable. These statements also relate to our future prospects, developments and business strategies.
     These forward looking statements are identified by the use of terms and phrases such as “anticipate”, “believe”, “could”, “estimate”, “expect”, “intend”, “may”, “plan”, “predict”, “project”, and similar terms and phrases, including references to assumptions. However, these words are not the exclusive means of identifying such statements. These statements are contained in many sections of this report, including “Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Although we believe that our plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, we cannot assure you that we will achieve those plans, intentions or expectations. We believe that the following factors, among others (including those described in “Part II, Item 1A. Risk Factors”), could affect our future performance and the liquidity and value of our securities and cause our actual results to differ materially from those expressed or implied by forward-looking statements made by us or on our behalf: the cyclical nature of the metals industry; decreases in the prices of zinc and nickel-related products; long-term declines in demand for zinc and nickel products due to competing technologies or materials; competition from global zinc and nickel manufacturers; our ability to implement our business strategy successfully; work stoppages and labor disputes; material disruptions at any of our manufacturing facilities, including for equipment, power failures or industrial accidents or explosions, including the explosion that occurred at our Monaca, Pennsylvania facility in July 2010; the extent of the damage resulting from the explosion, the impact of the explosion on continuing operations, the timing and cost of repairs and the availability and sufficiency of insurance; fluctuations in the costs or availability of our energy supplies; decreases in order volume from major customers; the costs of compliance with environmental, health and safety laws and responding to potential liabilities and changes under these laws; failure of our hedging strategies, including those relating to the prices of

energy, raw materials and zinc products; our ability to attract and retain key personnel; our ability to protect our intellectual property and know-how; our dependence on third parties for transportation services; and risks associated with future acquisitions, joint ventures or asset dispositions.
     There may be other factors that may cause our actual results to differ materially from the forward-looking statements. Our actual results, performance or achievements could differ materially from those expressed in, or implied by, the forward-looking statements. We can give no assurances that any of the events anticipated by the forward-looking statements will occur or, if any of them does, what impact they will have on our results of operations and financial condition. You should carefully read the factors referenced in the “Risk Factors” section of this report for a description of certain risks that could, among other things, cause our actual results to differ from these forward-looking statements.
     All forward-looking statements are qualified in their entirety by this cautionary statement, and we undertake no obligation to revise or update this Quarterly Report on Form 10-Q to reflect events or circumstances after the date hereof.

HORSEHEAD HOLDING CORP. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in thousands except per share amounts)
NOTE A—BASIS OF PRESENTATION
     The accompanying unaudited consolidated financial statements of Horsehead Holding Corp. and its subsidiaries as of June 30, 2010 and for the three and six months ended June 30, 2010 and June 30, 2009, have been prepared pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the 2010 presentation. Operating results for the three and six months ended June 30, 2010 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2010. The accompanying financial statements include the accounts of Horsehead Holding Corp. and all of its subsidiaries (collectively referred to as “the Company”, “we”, “us” or “our” or similar terms). All intercompany accounts and transactions have been eliminated. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009.
     The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to inventory reserves, bad debt reserves, environmental and asset retirement obligations, workers’ compensation liabilities, reserves for contingencies and litigation and fair value of financial instruments. Management bases its estimates on the Company’s historical experience and its expectations of the future and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.
NOTE B—RECENTLY ISSUED ACCOUNTING STANDARDS
     In June 2009, the Financial Accounting Standards Board (“FASB”) issued updated guidance centering on consolidation of variable interest entities. The updated guidance includes a requirement for an enterprise to perform an analysis to determine whether the enterprise’s variable interest or interests give it a controlling financial interest in a variable interest entity and a requirement for an enterprise to perform ongoing reassessments of whether it is the primary beneficiary of a variable interest entity and provides guidance for determining whether an entity is a variable interest entity. The update is effective for fiscal years beginning after November 15, 2009, and for interim periods within the first annual reporting period. The provisions had no significant effect on the Company’s consolidated financial statements.
NOTE C—ACQUISITION OF BUSINESS
     On December 31, 2009, the Company purchased all of the issued and outstanding capital stock of INMETCO, from Vale Inco Americas Inc. The Company also assumed certain financial assurance obligations associated with environmental regulatory requirements. The assurance was provided in 2009 in the form of a $5,890 letter of credit supported by a $6,185 increase in the Company’s restricted cash balance.
     The final purchase price of INMETCO, after post-closing adjustments, was allocated as follows:

     The Company’s cash balance is concentrated in two U.S. banks.

The fund did not invest in repurchase agreements.

The certificates of deposit had a four week maturity and had an interest rate of 0.4%. They were purchased through the Certificate of Deposit Account Registration Service (“CDARS”). CDARS allows a depositor to keep large deposits federally insured by investing in certificates of deposit in amounts covered by the Federal Deposit Insurance Corporation (“FDIC”). Under the program, the depositor invests an amount with a financial institution participating in the CDARS program. That financial institution purchases certificates of deposit from other participating financial institutions in amounts covered by the FDIC. The balances approximate fair value.

NOTE K—INCOME TAXES
     The Company’s effective tax rates were 39.5% and 37.6% for the three and six months ended June 30, 2010 respectively and 35.9% and 35.8% for the three and six months ended June 30, 2009, respectively. The provision or benefit for income taxes differs from the tax provision or benefit computed by applying the U.S. statutory federal income tax rate applied to net income before income taxes due primarily to state income taxes.
     The Company and its subsidiaries file income tax returns in the U.S. and various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. The tax years that remain subject to examination range from 2006 through 2009.
NOTE L—STOCK-BASED COMPENSATION
     The Company adopted a stock option plan in 2004 (as amended, the “2004 Plan”) which was amended and restated in December 2005 and November 2006. The 2004 Plan provides for the granting of options to acquire shares of common stock of the Company to key employees of the Company and its subsidiaries. A total of 1,685 shares are authorized and reserved for issuance under the 2004 Plan. All options granted under the 2004 Plan to date are fully vested due to the change in ownership of the Company in November 2006. The options may be exercised at any time prior to September 15, 2014. At June 30, 2010, there were 151 options outstanding, each with an exercise price of $1.01 per share and 4.20 years of remaining contractual life. The aggregate intrinsic value at June 30, 2010 of the options outstanding under the 2004 Plan was $986.
     In 2006, the Company adopted the Horsehead Holding Corp. 2006 Long-Term Equity Incentive Plan, which was amended and restated on June 11, 2007 (the “2006 Plan”) and which provides for grants of stock options, stock appreciation rights, restricted stock, restricted stock units, deferred stock units and other equity-based awards. Directors, officers and other employees of the Company, as well as others performing services for the Company, are eligible for grants under the 2006 Plan. The 2006 Plan is administered by the compensation committee of the Company’s Board of Directors (the “Committee”).
     A total of 1,489 shares of the Company’s common stock were initially authorized for issuance under the 2006 Plan, which amount increases annually by an amount equal to 1% of the number of shares on the Company’s common stock

outstanding or such lesser amount determined by the Company’s Board of Directors (the “Board”). The number of shares available for issuance under the 2006 Plan is subject to adjustment in the event of a reorganization, stock split, merger or similar change in the corporate structure or the outstanding shares of common stock. In the event of any of these occurrences, the Committee may make any adjustments considered appropriate to, among other things, the number and kind of shares, options or other property available for issuance under the 2006 Plan or covered by grants previously made under the 2006 Plan. The shares available for issuance under the 2006 Plan may be, in whole or in part, authorized and unissued or held as treasury shares.
     On January 16, 2007, the Board authorized the issuance of options to purchase 1,085 shares of the Company’s common stock to certain officers and employees of the Company under the 2006 Plan. The exercise price is $13.00 per share. The options have a term of ten years and vest ratably over a five-year period from date of grant. Generally, the vested options may be exercised any time after November 30, 2007 and before the earlier of January 24, 2017 or the date of the option holder’s employment termination.
     At June 30, 2010, there were 1,042 options outstanding, each with an exercise price of $13.00 per share and 6.54 years of remaining contractual life. The related compensation expense for the three and six months ended June 30, 2010 was $323 and $655, respectively. For the three and six months ended June 30, 2009, the compensation expense was $290 and $627, respectively. Unrecognized compensation expense as of June 30, 2010 was $2,042. As of June 30, 2010, 626 options were vested and fully exercisable. In the first six months of 2010, 3 options were forfeited.
     In the first six months of 2010, the Company granted a total of 197 restricted stock units at an average grant date fair value of $10.00 per unit. In the first quarter of 2009, the Company granted a total of 318 restricted stock units at a grant date fair value of $4.96 per unit. The units vest over a five year service period. Upon vesting, the underlying stock will be issued for par value. The related compensation expense for the three and six months ended June 30, 2010 was $263 and $537, respectively. For the three and six months ended June 30, 2009, the compensation expense was $208 and $437, respectively. Unrecognized compensation expense as of June 30, 2010 was $3,873. As of June 30, 2010, there were 724 restricted stock units outstanding. The remaining contractual life ranged from .75 years to 4.88 years at June 30, 2010.
NOTE M—ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
     The Company’s business consists principally of the sale of zinc and nickel-based products. As a result, its results of operations are subject to risk of fluctuations in the market prices of these metals. While the Company’s finished products are generally priced based on a spread to the price of zinc or nickel, as applicable, on the London Metal Exchange (“LME”), its revenues are impacted significantly by changes in the market prices of these metals. The Company pursues various hedging strategies as described below to reduce its exposure to movements in the price of zinc.
     The Company’s marketing strategy includes a metal hedging program that allows customers to secure a firm price for future deliveries under a sales contract. Hedges are entered into based on firm sales contracts to deliver specified quantities of product on a monthly basis for terms generally not exceeding one year. The Company’s raw material purchases related to such firm price contracts are at varying zinc and copper prices that are based on the LME. In order to protect its cash flow related to firm price sales contracts, the Company enters into fixed-to-variable swap contracts to convert the LME-based fixed sales price back to variable. Thus, if raw material costs increase as a result of LME zinc or copper price increases, the related sales value and related cash flows will also increase. As of June 30, 2010, the fixed portions of these contracts ranged from a monthly average of $0.85 per pound to $2.96 per pound.
     The Company disposes of the lead co-product of its EAF dust recycling operation under a disposal agreement. The disposal costs are similarly affected by the LME lead price fluctuations. As of June 30, 2010, the fixed portion of these contracts was $1.11 per pound.
     At June 30, 2010, approximately $10,235 of future swap contracts were outstanding all of which settle at various dates up to and including April 30, 2011. The Company received cash of $303 and $561 from the settlement of such contracts for the six months ended June 30, 2010 and 2009, respectively.
     The Company purchased put options for various quantities of zinc to act as a financial hedge and to lend stability to its revenue stream. In October 2008, the Company purchased options for approximately 90 tons of zinc for 2009. The cost was

(Amounts in thousands except per share amounts)
$10,472 and the strike price was $0.50 per pound. At the time of the purchases, they represented approximately 60% of the Company’s anticipated sales volume for 2009. In 2009, the Company purchased options for approximately 100 tons of zinc for 2010. The cost of the options was $5,276 and the strike price was $0.65 per pound. At the time of the purchases, the options represented approximately 80% of the Company’s anticipated sales volume for 2010. In April of 2010, the Company purchased options for approximately 25 tons of zinc for 2011. The cost was $882 and the strike price is $0.65 per pound.
     The options settle monthly on an average LME pricing basis. For the three and six months ended June 30, 2010 and 2009, the average LME zinc prices were above the strike prices for the contracts. Consequently, they expired with no settlement payment due the Company.
     The gains and losses resulting from the Company’s hedging activities are recorded in the Consolidated Statements of Operations as indicated in the table below.

     The fair values of derivative instruments are based upon a comparison of the Company’s internal valuations to the valuations provided by third party counterparties with whom they have entered into substantially identical derivative contracts. The Company also compares the counterparties valuations to ensure that there is an acceptable level of consistency among them. The put option valuations utilize forward pricing and an implied volatility of the underlying commodity as well as interest rate forwards and are therefore subject to fluctuation based on the movements of the commodity markets. The swap valuations are based on the official LME closing valuations at the end of the trading day on June 30, 2010 and December 31, 2009, using the mid-point of the closing bid and ask prices on all open swap positions regardless of the holder. The closing prices are supervised by the London Clearing House and are regulated by the Financial Services Authority, the financial regulatory body in the United Kingdom.
     The Company is exposed to credit loss in cases where counter-parties with which they have entered into derivative transactions are unable to pay the Company when they owe the Company funds as a result of agreements with them. To minimize the risk of such losses, the Company uses highly rated financial institutions as counter-parties that meet certain requirements. The Company currently does not anticipate that any of the counter-parties will default on their obligations. The Company does not require collateral and does not enter into master netting arrangements.
NOTE N—CONTINGENCIES
     The Company is subject to federal, state and local laws designed to protect the environment and believes that as a general matter, its policies, practices and procedures are properly designed to reasonably prevent risk of environmental damage and financial liability to the Company.

     The Company is party to various litigation, claims and disputes, including labor regulation claims and Occupational Safety and Health Act (“OSHA”) and environmental regulation violations, some of which are for substantial amounts, arising in the ordinary course of business. While the ultimate effect of such actions cannot be predicted with certainty, the Company expects that the outcome of these matters will not result in a material adverse effect on its business, financial condition or results of operations.
NOTE O—EARNINGS PER SHARE
     Basic earnings (loss) per common share (“EPS”) is computed by dividing net income or loss by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed similarly to basic earnings per share except that the denominator is increased to include the number of shares that would have been outstanding if potentially dilutive common shares had been issued. Diluted EPS for periods with a net loss is calculated by dividing the net loss by the weighted average number of shares outstanding. The Company uses the treasury stock method when calculating the dilutive effect in basic EPS.
     The information used to compute basic and diluted earnings (loss) per share follows:

NOTE R — SUBSEQUENT EVENTS
     On July 22, 2010, an explosion occurred at the Company’s Monaca, PA facility which resulted in two fatalities in the plant’s zinc oxide refining facility. The zinc refinery remains shutdown pending completion of an investigation and assessment of the damage. Teams from the U.S. Occupational, Safety and Health Administration (OSHA) and the U.S. Chemical Safety & Hazard Investigation Board (CSB) are investigating the cause and the circumstances that may have contributed to the occurrence of this incident. The Company is cooperating fully with these investigations. In addition, the Company’s insurance underwriters and the Company are conducting their own investigations into the cause and the circumstances that contributed to this incident. The United Steel Workers union is also participating in the investigations.
     A preliminary assessment of the damage indicates that each of the 10 columns used to produce zinc oxide and refined zinc metal in the refining facility will need to be rebuilt before production can be safely restarted using these columns. It was further determined that the rebuilding process will be delayed pending results from the accident investigation to assure that all safety measures are considered before production begins. The accident investigation may take several weeks to complete. It is estimated that production capabilities in the refining facility may not be fully restored until early next year.
     While the smelting facility and other operations at the Monaca plant remain active, they are operating at a reduced rate. The smelting facility is currently operating five of its six furnaces producing zinc metal. The operating level of the smelter will be adjusted based on market conditions and as operations at the zinc refining facility are restarted. The Company will pursue recovery of the cost of repairs and the lost profit from its zinc oxide and refined metal during the rebuilding period, subject to customary deductibles, under the Company’s business interruption and property insurance. While the full financial impact of this incident is not known at this time, absent insurance recoveries, earnings will be impaired for the remainder of the year. The Company believes that it will continue to have adequate liquidity to support the business.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
General
     This discussion should be read in conjunction with the Notes to Consolidated Financial Statements included herein and the Notes to Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009, which was filed with the SEC on March 16, 2010.
Overview
Our History
     We are a leading U.S. producer of specialty zinc and zinc-based products. Our products are used in a wide variety of applications, including in the galvanizing of fabricated steel products and as components in rubber tires, alkaline batteries, paint, chemicals and pharmaceuticals and as a remelt alloy in the production of stainless steel. We believe that we are the largest refiner of zinc oxide and Prime Western (“PW”) zinc metal in North America. We believe we are also the largest North American recycler of electric arc furnace (“EAF”) dust, a hazardous waste produced by the carbon steel mini-mill manufacturing process. As a result of the INMETCO acquisition, we believe we are also a leading recycler of EAF dust and other nickel-bearing waste generated by specialty steel producers and a leading recycler of nickel-cadmium (“Ni-Cd”) batteries in North America. We, together with our predecessors, have been operating in the zinc industry for more than 150 years and in the nickel-bearing waste industry for more than 30 years.
     While we vary our raw material inputs, or feedstocks, based on cost and availability, we generally produce our zinc and nickel-based products using nearly 100% recycled materials, including metal recovered from our EAF dust recycling operations. We believe that our ability to convert recycled zinc into finished products results in lower feed costs than for smelters that rely primarily on zinc concentrates. Our four EAF dust recycling facilities also generate service fee revenue from steel mini-mills by providing a convenient and safe means for recycling their EAF dust. In 2008, we began construction of a new EAF dust processing facility located in South Carolina. We placed the first of two kilns into production in mid-April 2010. INMETCO provides recycling services, some of which is on a tolling basis, from a single production facility in Ellwood City, Pennsylvania.
Economic Conditions and Outlook
     The economy remains weak but continued to slowly improve through the first two quarters of 2010. Our zinc product shipment levels for the first two quarters of 2010 continued to improve over the quarterly shipment levels for 2009 but continued to lag the quarterly shipment levels for the first three quarters of 2008. In March 2010, we started operations of our sixth furnace at our Monaca smelter. We expect improvements in economic conditions to be slow in the near term. Our results, particularly in comparison to the first two quarters of 2009, reflect the impact this limited improvement has had on the markets we serve, in particular the tire and rubber market, the hot-dipped galvanizing market and the EAF dust recycling market.
Factors Affecting Our Operating Results
     Market Price for Zinc and Nickel. Since we generate the substantial majority of our net sales from the sale of zinc and nickel-based products, our operating results depend greatly on the prevailing market price for zinc and nickel. Our principal raw materials are zinc extracted from recycled EAF dust, for which we receive revenue from the carbon steel mini-mill companies, and other zinc-bearing secondary materials (“purchased feedstock” or “purchased feed”) that we purchase from third parties. Costs to acquire and recycle EAF dust, which, during the first six months of 2010, represented approximately 63% of our raw materials, are not directly impacted by fluctuations in the market price of zinc on the London Metal Exchange (“LME”). However, the cost for the remaining portion of our raw materials is directly impacted by changes in the market price of zinc. The price of our finished products is also impacted directly by changes in the market price of zinc and nickel, which can result in rapid and significant changes in our monthly revenues. Zinc prices experienced a period of general decline between 2000 and 2004, primarily due to increased exports from China and declines in global zinc consumption. During 2004, however, zinc prices began to recover, primarily due to increases in global zinc demand, including in China, and to declines in global production due to closed or permanently idled zinc mining and smelting capacity. Zinc prices rose throughout 2005 and 2006 to a historical high of $2.08 per pound on December 5, 2006 then

began a steady decline to $0.47 per pound on December 17, 2008 for an average of $0.85 per pound for 2008. Zinc prices began to strengthen in 2009 reaching a high of $1.17 on December 31, 2009 for an average of $0.75 for the year.
     Monthly average zinc prices have fluctuated between $0.79 per pound and $1.10 per pound in the first six months of 2010, for an average of $0.98 per pound for the period. The movement and level of zinc prices reflect the gradual improvement in economic conditions and continued investor activity in the metal markets. For the six months ended June 30, 2010, LME average nickel prices ranged from $8.36 per pound to $11.81 per pound and averaged $9.62 per pound.
     In 2009, we purchased put options for 2010 at a cost of $5.3 million to serve as a hedge and to mitigate the effects of decreases in the LME average zinc price. In 2010, we purchased additional put options for 2011 at a cost of $0.9 million. Through the purchase of the options, we will receive a minimum price per pound for the quantity hedged. The options have a strike price of $0.65 per pound. At the time of the purchase the options for 2010 represented approximately 80% of our expected zinc production in 2010.
     Demand for Zinc and Nickel-Based Products. We generate revenue from the sale of zinc and nickel-based products and copper-based powders, as well as from the collection and recycling of EAF dust. Demand for our products increased in the first two quarters of 2010 from the fourth quarter of 2009. Our production of zinc products for the first six months of 2010 increased to an annual rate of 131,000 tons from 106,000 tons for 2009.
     The increase in weekly domestic steel production that began in the second quarter of 2009 continued through the second quarter of 2010, thereby increasing the amount of EAF dust generated and the demand for our EAF dust recycling services. We placed the first of two kilns in production at our Barnwell, South Carolina facility in mid-April of 2010. The starting date for the second kiln will be determined by market conditions.
     The table below illustrates historical production and sales volumes and revenues for zinc products and EAF dust:

     Cost of Sales (excluding depreciation and amortization). Our cost of producing zinc and nickel-based products consists principally of purchased feedstock, energy, maintenance and labor costs. In the first six months of 2010, approximately 25% of our zinc production costs were purchased-feedstock-related, compared to 15% for the first six months of 2009. The increase reflects a 37.2% increase in production from the first six months of 2009 and the significant increase in the LME average zinc price that began in 2009, partially offset by our efforts to increase the use of EAF dust-based feedstock. The remaining 75% of our zinc production costs in the first six months of 2010 were conversion-related. A portion of our conversion costs do not change proportionally with changes in production volume. Consequently, as volume changes our conversion cost per ton changes inversely. The increase in our production volume in 2010 has caused our conversion cost per ton to decrease compared to the first six months of 2009. Other components of cost of sales include transportation costs, as well as other manufacturing expenses. The main factors that influence our cost of sales as a percentage of net sales are fluctuations in zinc and nickel prices, production and shipment volumes, efficiencies, energy costs and our ability to implement cost control measures aimed at improving productivity. We purchase our purchased feedstock at a discount to the LME price of zinc.
     We value our inventories using the weighted average actual cost method. Under this method, the cost of our purchased feedstock generally takes three to four months to flow through our cost of sales. In an environment of declining LME average zinc or nickel prices, our inventory cost can exceed the market value of our finished goods. A significant lower-of-cost-or-market (“LCM”) adjustment can result. In the first quarter of 2009, we recorded an LCM adjustment of $2.8 million. No LCM adjustment was recorded in the first two quarters of 2010.
     Selling, General and Administrative Expenses. Our selling, general and administrative expenses consist of all sales and marketing expenditures, as well as administrative overhead costs, such as salary and benefit costs for sales personnel and administrative staff, expenses related to the use and maintenance of administrative offices, other administrative expenses,

including expenses relating to logistics and information systems and legal and accounting expense, and other selling expenses, including travel costs. Salary and benefit costs historically have comprised the largest single component of our selling, general and administrative expenses. Selling, general and administrative expenses as a percent of net sales historically have been impacted by changes in salary and benefit costs, as well as by changes in selling prices.
Explosion at our Monaca, Pennsylvania facility
     On July 22, 2010, an explosion occurred at our Monaca, PA facility which resulted in two fatalities in the plant’s zinc oxide refining facility. The zinc refinery remains shutdown pending completion of an investigation and assessment of the damage. Teams from the U.S. Occupational, Safety and Health Administration (OSHA) and the U.S. Chemical Safety & Hazard Investigation Board (CSB) are investigating the cause and the circumstances that may have contributed to the occurrence of this incident. We are cooperating fully with these investigations. In addition, we and our insurance underwriters are conducting our own investigations into the cause and the circumstances that contributed to this incident. The United Steel Workers union is also participating in the investigations.
     A preliminary assessment of the damage indicates that each of the 10 columns used to produce zinc oxide and refined zinc metal in the refining facility will need to be rebuilt before production can be safely restarted using these columns. It was further determined that the rebuilding process will be delayed pending results from the accident investigation to assure that all safety measures are considered before production begins. The accident investigation may take several weeks to complete. We plan to restart our idled Larvik furnaces in September to begin producing limited quantities of zinc oxide, however, it is estimated that production capabilities in the refining facility may not be fully restored until early next year.
     While the smelting facility and other operations at the Monaca plant remain active, they are operating at a reduced rate. The smelting facility is currently operating five of its six furnaces producing zinc metal. The operating level of the smelter will be adjusted based on market conditions and as operations at the zinc refining facility are restarted. We will pursue recovery of the cost of repairs and the lost profit from our zinc oxide and refined metal during the rebuilding period, subject to customary deductibles, under our business interruption and property insurance. While the full financial impact of this incident is not known at this time, absent insurance recoveries, earnings will be impaired for the remainder of the year. We believe that we will continue to have adequate liquidity to support the business.
Trends Affecting Our Business
     Our operating results are and will be influenced by a variety of factors, including:
    LME price of zinc and nickel;
 
    changes in cost of energy and fuels;
 
    gain and loss of customers;
 
    pricing pressures from competitors, including new entrants into the EAF dust or nickel-bearing waste recycling market;
 
    increases and decreases in the use of zinc and nickel-based products;
 
    expansions into new products and expansion of our capacity, which requires us to incur costs prior to generating revenues;
 
    expenditures required to comply with environmental and other operational regulations;
 
    access to credit by our customers; and
 
    our operational efficiency improvement programs.
     We have experienced fluctuations in our sales and operating profits in recent years due to fluctuations in zinc prices. Historically, zinc prices have been extremely volatile, and we expect that volatility to continue. For example, the LME price of zinc rose from $0.58 per pound on December 31, 2004 to $2.08 per pound on December 5, 2006 and fell to as low as $0.47 per pound on December 17, 2008. In 2009, the LME price of zinc ranged from a low of $0.48 per pound on February 20,

15


Table of Contents

2009 to a high of $1.17 per pound on December 31, 2009. The average price was $0.98 per pound for the first six months of 2010. Changes in zinc pricing have impacted our sales revenue since the prices of the products we sell are based primarily on LME zinc prices, and they have impacted our costs of production, since the prices of some of our feedstocks are based on LME zinc prices. Therefore, since a large portion of our sales and a portion of our expenses are affected by the LME zinc price, we expect that changing zinc prices will continue to impact our operations and financial results in the future and any significant drop in zinc prices will negatively impact our results of operations. We employ various hedging instruments in order to attempt to reduce the impact of decreases in the selling prices of a portion of our expected production.
     Energy is one of our most significant costs. Our processes rely on electricity, coke and natural gas in order to operate. Our freight operations depend heavily on the availability of diesel fuel, and our Monaca, Pennsylvania power plant uses coal to generate electricity for our operations in that facility. Energy costs, particularly for electricity, natural gas, coal, coke and diesel fuel, have been volatile in recent years and have exceeded long-term historical averages. These fluctuations impact our manufacturing costs and contribute to earnings volatility.
     The historically high zinc prices in 2006 into 2008 also made it attractive for new competitors to enter the EAF dust recycling market to compete for dust generated by existing EAF producers as well as new EAF capacity. The entry of new competitors could have an adverse impact on our price realization and market share from EAF dust recycling. For example, Steel Dust Recycling began operations at its Waelz kiln facility located in Alabama in 2008, and The Heritage Group built an EAF dust processing facility in Arkansas and began operations in 2009.
     Our zinc products compete with other materials in many of their applications, and in some cases our customers may shift to new processes or products. For example, our zinc is used by steel fabricators in the hot dip galvanizing process, in which steel is coated with zinc in order to protect it from corrosion. Demand for our zinc as a galvanizing material may shift depending on how customers view the respective merits of hot dip galvanizing and paint. Our stainless steel customers face competition from producers of material containing lower levels of nickel, which could have an impact on the demand for our nickel-based products. Our ability to anticipate shifts in product usage and to produce new products to meet our current and future customers’ needs will significantly impact our operating results. We also face intense competition from regional, national and global providers of zinc based products, and the growth of any of those competitors could reduce our market share and negatively impact our operating results.
     Finally, our business is subject to a wide variety of environmental and other regulations and our operations expose us to a wide variety of potential liabilities. Our total cost of environmental compliance at any time depends on a variety of regulatory, technical and factual issues, some of which cannot be anticipated. Changes in regulations and/or our failure to comply with existing regulations can result in significant capital expenditure requirements or penalties.
Summary of Critical Accounting Policies and Estimates
     Our Consolidated Financial Statements and the notes thereto for the fiscal year ended December 31, 2009 included in our Annual Report on Form 10-K, which was filed with the SEC on March 16, 2010, contain a summary of significant accounting policies followed by us in the preparation of our consolidated financial statements. These policies were also followed in preparing the consolidated financial statements as of June 30, 2010 and for the three and six months ended June 30, 2010 and 2009. Certain of these accounting policies are described below.
Inventories
     Inventories, which consist primarily of zinc and nickel-bearing materials and supplies and spare parts, are valued at the lower of cost or market using a moving average cost method. Raw materials are purchased, as well as produced from the processing of EAF dust. Supplies and spare parts inventory used in the production process are purchased. Work-in-process and finished goods inventories are valued based on the costs of raw materials plus applicable conversion costs, including depreciation and overhead costs relating to associated process facilities.
     Zinc and nickel are traded as commodities on the LME, and, accordingly, product inventories are subject to price fluctuations. When reviewing inventory for the lower of cost or market, we consider the forward prices as quoted on the LME as of the reporting date in determining our estimate of net realizable value to determine if an adjustment is required. Our product revenues are based on the current or prior months’ LME average prices. The LME average price upon which our product revenue is based has been reasonably correlated with the forward LME prices that we use to make the lower of cost or market adjustments.

Financial Instruments
     The following methods are used to estimate the fair value of our financial instruments.
     Cash and cash equivalents, accounts receivable, notes payable due within one year, accounts payable and accrued expenses approximate their fair value due to the short-term nature of these instruments.
     We enter into certain financial swap and financial option instruments that are carried at fair value. We recognize changes in fair value within the consolidated statements of operations as they occur.
     We do not purchase, hold or sell derivative financial instruments unless we have an existing asset or obligation or anticipate a future activity that is likely to occur and will result in exposing us to market risk. We use various strategies to manage our market risk, including the use of derivative instruments to limit, offset or reduce such risk. Derivative financial instruments are used to manage well-defined commodity price risks from our primary business activity. The fair values of derivative instruments are based upon a comparison of our internal valuations to the valuations provided by third-party counterparties with whom we have entered into substantially identical derivative contracts. We also compare these counterparty valuations to ensure that there is an acceptable level of consistency among them. The valuations utilize forward pricing of the underlying commodity and are therefore subject to fluctuation based on the movements of the commodity markets.
     We are exposed to credit loss in cases where counter-parties with which we have entered into derivative transactions are unable to pay us when they owe us funds as a result of agreements with them. To minimize the risk of such losses, we use highly rated counter-parties that meet certain requirements. We currently do not anticipate that any of our counter-parties will default on their obligations to us.
Impairment
     We review the carrying value of our long-lived assets for impairment whenever events or circumstances indicate that the carrying amounts may not be recoverable. We examined our assets as of June 30, 2010 and found no events that would suggest a potential impairment. We have no goodwill. In the event we would determine the carrying amounts would not be recovered, an impairment charge would be recorded for the difference between the fair value and the carrying value.
Recently Issued Accounting Pronouncements
     In June 2009, the Financial Accounting Standards Board (“FASB”) issued updated guidance centering on consolidation of variable interest entities. The updated guidance includes a requirement for an enterprise to perform an analysis to determine whether the enterprise’s variable interest or interests give it a controlling financial interest in a variable interest entity and a requirement for an enterprise to perform ongoing reassessments of whether it is the primary beneficiary of a variable interest entity and provides guidance for determining whether an entity is a variable interest entity. The updated guidance is effective for fiscal years beginning after November 15, 2009, and for interim periods within the first annual reporting period. The provisions had no significant effect on our consolidated financial statements.

Three Months Ended June 30, 2010 Compared with Three Months Ended June 30, 2009
     Net sales. Consolidated net sales increased $50.9 million, or 107.0%, to $98.5 million for the three months ended June 30, 2010 compared to $47.6 million for the three months ended June 30, 2009. The increase includes a $39.6 million increase in net sales for Horsehead Corporation (“Horsehead”) and $11.3 million in net sales related to INMETCO.
     Net sales relating to Horsehead increased $39.6 million, or 83.2%, to $87.2 million for the three months ended June 30, 2010 compared to $47.6 million from the three months ended June 30, 2009. The increase was a result of a $22.0 million increase in price realization, due primarily to a higher average LME zinc price for the second quarter of 2010 versus the second quarter of 2009, a $15.5 million increase in sales volume reflecting increases in shipments across all major product lines and an increase in EAF dust receipts. Our net sales were further increased by $3.1 million relating to our hedging activity. Net sales were decreased by a $1.0 million decrease in co-product and miscellaneous sales. The $3.1 million increase in net sales relating to our hedging positions consisted of a favorable non-cash mark to market adjustment of $1.2 million for the three months ended June 30, 2010 versus an unfavorable adjustment of $1.9 million for the three months ended June 30, 2009. Zinc product shipments were 36,860 tons for the three months ended June 30, 2010, or 33,199 tons on a zinc contained basis, compared to 28,530 tons, or 26,031 tons on a zinc contained basis, for the three months ended June 30, 2009.
     The average sales price realization for zinc products on a zinc contained basis, excluding the effects from the non-cash mark to market adjustments of our open hedge positions, was $1.08 per pound for the three months ended June 30, 2010, compared to $0.75 per pound for the three months ended June 30, 2009. The increase reflects the 36.7% increase in the average LME zinc price for the three months ended June 30, 2010 compared to the three months ended June 30, 2009. The increase was caused by the general economic recovery that began in 2009 and continued into 2010.
     Net sales of zinc metal increased $12.6 million, or 56.5%, to $34.9 million for the three months ended June 30, 2010 compared to $22.3 million for the three months ended June 30, 2009. The increase was attributable primarily to a $9.0 million increase in price realization and a $3.6 million increase in sales volume. The increase in price realization was attributable to a higher average LME zinc price for the second quarter of fiscal 2010 versus the second quarter of fiscal 2009. The increase in shipment volume reflects the gradual improvement in demand for our products that began in the second quarter of 2009 and continued throughout the second quarter of 2010.
     Net sales of zinc oxide increased $19.5 million, or 118.9%, to $35.9 million for the three months ended June 30, 2010, compared to $16.4 million for the three months ended June 30, 2009. The increase was attributable to an $11.9 million increase in price realization and a $7.6 million increase in sales volume. The increase in price realization reflects the increase of the average LME zinc prices over the past twelve months partially offset by the lag effect of pricing a majority of our zinc oxide shipments on prior months’ average LME zinc prices. We realized a premium to the LME on sales of zinc oxide in the second quarter of 2010 versus a discount to the LME in the second quarter of 2009, both reflecting the lag effect and the movements of the average LME zinc prices from the immediately preceding quarters. The volume increase was caused primarily by increased shipments to our largest tire customers reflecting the strengthening in the market that began in the second quarter of 2009 and continued into 2010.
     Net sales of zinc and copper-based powder increased $1.9 million, or 111.8%, to $3.6 million for the three months ended June 30, 2010 compared to $1.7 million for the three months ended June 30, 2009. The increase was attributable primarily to increases in prices and shipment volumes of our copper-based powders.
     Revenues from EAF dust recycling increased $3.5 million, or 52.7%, to $10.1 million for the three months ended June 30, 2010 compared to $6.6 million for the three months ended June 30, 2009. Increased volumes caused revenues to increase by $4.1 million. A 5.4% decrease in price realization on EAF dust recycling fees for the three months ended June 30, 2010 compared to the three months ended June 30, 2009 resulted in a decrease in net sales of $0.6 million. EAF dust receipts for the three months ended June 30, 2010 increased 61.4% to 137,578 tons compared to 85,240 tons for the three months ended June 30, 2009, reflecting the increase in steel production that began in the third quarter of 2009 and continued into 2010. The increase also reflects the increase in volume associated with the purchase of the customer contracts from ESOI in June 2009. According to data from the American Iron & Steel Institute, reported steel production for the three months ended June 30, 2010 increased 66.4% from the three months ended June 30, 2009.
     Cost of sales (excluding depreciation and amortization). Consolidated cost of sales increased $25.9 million, or 48.1%, to $79.8 million for the three months ended June 30, 2010, compared to $53.9 million for the three months ended June 30, 2009. The increase includes an $18.3 million increase in cost of sales for Horsehead and $7.6 million in cost of

sales related to INMETCO. As a percentage of consolidated net sales, consolidated cost of sales was 81.0% for the three months ended June 30, 2010, compared to 113.2% for the three months ended June 30, 2009.
     Cost of sales related to Horsehead increased $18.3 million, or 33.9%, to $72.2 million for the three months ended June 30, 2010, compared to $53.9 million for the three months ended June 30, 2009. As a percentage of net sales related to Horsehead, cost of sales was 82.8% for the three months ended June 30, 2010, compared to 113.2% for the three months ended June 30, 2009. The change in percentage reflects the net effect of changes in the average LME zinc prices on our net sales and cost of sales. Changes in the average LME zinc price are restricted to the purchased feed component of our cost of sales; therefore any changes in the average LME zinc price have a smaller effect on our cost of sales than on our net sales. As a percentage of net sales related to INMETCO, cost of sales related to INMETCO was 64.8% for the three months ended June 30, 2010.
     The cost of zinc material and other products sold increased $14.9 million, or 29.2%, to $65.7 million for the three months ended June 30, 2010, compared to $50.8 million for the three months ended June 30, 2009. The increase was primarily the result of a $11.5 million increase in shipment volume across all major product lines, a $9.0 million increase in the cost of products shipped and a $5.6 million decrease in recycling and other costs. The increases reflect higher feed costs and higher conversion costs for the three months ended June 30, 2010 compared to the three months ended June 30, 2009, driven in part by an increase in production levels. Purchased feed costs were increased by $9.3 million, reflecting both the higher LME average zinc price as well as an increased cost of purchased feeds we pay expressed as a percentage of the LME. The increase in our purchased feed costs also reflects a 72.7% increase in the number of tons of purchased feed consumed.
     Horsehead’s conversion costs were $11.9 million higher in the three months ended June 30, 2010 than in the three months ended June 30, 2009. The increase reflects a $6.7 million increase in utility costs, a $3.0 million increase in labor costs and a $1.8 million increase in maintenance and supplies costs. These increases were driven primarily by higher production levels for the three months ended June 30, 2010 as compared to the three months ended June 30, 2009 in response to the gradual economic recovery that began late in 2009 and continued into 2010. The increase in production levels for the three months ended June 30, 2010 compared to the three months ended June 30, 2009 more than offset the increase in conversion costs on a per ton basis. Our conversion cost per ton decreased for the three months ended June 30, 2010 compared to the three months ended June 30, 2009.
     The cost of EAF dust services increased $3.4 million, or 110.6%, to $6.5 million for the three months ended June 30, 2010 compared to $3.1 million for the three months ended June 30, 2009 primarily reflecting a 61.4% increase in volume of EAF dust received partially offset by an increase in transportation costs.
     Depreciation and amortization. Consolidated depreciation and amortization expense increased $0.6 million, or 16.1%, to $4.2 million for the three months ended June 30, 2010 compared to $3.6 million for the three months ended June 30, 2009.
     Selling, general and administrative expenses. Selling, general and administrative expenses increased $1.0 million to $5.0 million for the three months ended June 30, 2010, compared to $4.0 million for the three months ended June 30, 2009. Horsehead related costs increased $0.5 million, primarily reflecting an increase in labor costs partially offset by a decrease in bad debt expense. Selling, general and administrative expenses relating to INMETCO were $0.7 million.
     Interest expense. Interest expense decreased $0.3 million to $0.3 million for the three months ended June 30, 2010, compared to $0.6 million for the three months ended June 30, 2009. The decrease largely reflects a $0.4 million reduction in expenses related to the credit facility we cancelled in December, 2009, partially offset by a $0.2 million increase in accretion expense associated with the liability we incurred to purchase the ESOI EAF dust contracts in June of 2009.
     Income tax provision (benefit). Our income tax provision was $3.7 million for the three months ended June 30, 2010, compared to an income tax benefit of $(5.2) million for the three months ended June 30, 2009. Our estimated annual effective tax rate for 2010 changed from 35.9% as of March 31, 2010 to 37.6% as of June 30, 2010. The change in the annual rate primarily reflects the combined effect of a reduction in our projected pre-tax income for 2010, brought about by a reduction in the expected price of zinc, and the tax effect of temporary differences. The change in the annual rate was reflected in our effective rate for the three months ended June 30, 2010. Our effective tax rates were 39.5% for the three months ended June 30, 2010 and 35.9% for the three months ended June 30, 2009.
     Net income (loss). For the reasons stated above, our net income was $5.7 million for the three months ended June 30, 2010, compared to a net loss of $(9.3) million for the three months ended June 30, 2009.

Six Months Ended June 30, 2010 Compared with Six Months Ended June 30, 2009
     Net sales. Consolidated net sales increased $108.1 million, or 123.6%, to $195.5 million for the six months ended June 30, 2010 compared to $87.4 million for the six months ended June 30, 2009. The increase includes an $82.3 million increase in net sales for Horsehead and $25.8 million in net sales related to INMETCO.
     Net sales relating to Horsehead increased $82.3 million, or 94.2%, to $169.7 million for the six months ended June 30, 2010, compared to $87.4 million from the six months ended June 30, 2009. The increase was a result of a $49.6 million increase in price realization, due primarily to a higher average LME zinc price for the first six months of 2010 versus the first six months of 2009, a $28.0 million increase in sales volume reflecting increases in shipments across all major product lines and an increase in EAF dust receipts. Our net sales were further increased by $6.6 million relating to our hedging activity. Co-product and miscellaneous sales decreased $1.9 million. The $6.6 million increase in net sales relating to our hedging positions consisted of a favorable non-cash adjustment of $0.5 million for the six months ended June 30, 2010 versus an unfavorable non-cash adjustment of $6.1 million for the six months ended June 30, 2009. Zinc product shipments were 70,268 tons for the six months ended June 30, 2010, or 63,317 tons on a zinc contained basis, compared to 56,191 tons, or 53,138 tons on a zinc contained basis, for the six months ended June 30, 2009.
     The average sales price realization for zinc products on a zinc contained basis, excluding the effects from the non-cash mark to market adjustments of our open hedge positions, was $1.11 per pound for the six months ended June 30, 2010, compared to $0.71 per pound for the six months ended June 30, 2009. The increase reflects the 63.0% increase in the average LME zinc price for the six months ended June 30, 2010 compared to the six months ended June 30, 2009. The increase reflected the general economic recovery that began in 2009 and continued into 2010.
     Net sales of zinc metal increased $31.4 million, or 80.1%, to $70.6 million for the six months ended June 30, 2010, compared to $39.2 million for the six months ended June 30, 2009. The increase was attributable primarily to a $25.5 million increase in price realization and a $5.9 million increase in sales volume. The increase in price realization was attributable to a higher average LME zinc price for the first six months of 2010 versus the first six months of 2009 partially offset by a lower average premium to the LME on zinc products sold for the six months of 2010 versus the first six months of 2009. The increase in shipment volume reflects the gradual improvement in demand for our products that began in the second quarter of 2009 and continued throughout the second quarter of 2010.
     Net sales of zinc oxide increased $37.1 million, or 115.6%, to $69.2 million for the six months ended June 30, 2010, compared to $32.1 million for the six months ended June 30, 2009. The increase was attributable to a $25.1 million increase in price realization and a $12.0 million increase in sales volume. The increase in price realization reflects the increase of the average LME zinc prices over the past twelve months partially offset by the lag effect of pricing a majority of our zinc oxide shipments on prior months’ average LME zinc prices. We realized a premium to the LME on sales of zinc oxide in the first six months of 2010 and 2009. The volume increase was caused primarily by increased shipments to our largest tire customers reflecting the strengthening in the market that began in the second quarter of 2009 and continued into 2010.
     Net sales of zinc and copper-based powder increased $3.8 million, or 122.6%, to $6.9 million for the six months ended June 30, 2010, compared to $3.1 million for the six months ended June 30, 2009. The increase was attributable primarily to increases in prices and shipment volumes of our copper-based powders.
     Revenues from EAF dust recycling increased $5.2 million, or 36.3%, to $19.6 million for the six months ended June 30, 2010, compared to $14.4 million for the six months ended June 30, 2009. Increased volumes caused revenues to increase by $9.3 million. A 17.2% decrease in price realization on EAF dust recycling fees for the six months ended June 30, 2010 compared to the six months ended June 30, 2009 resulted in a decrease in net sales of $4.1 million. EAF dust receipts for the six months ended June 30, 2010 increased 64.6% to 272,666 tons compared to 165,644 tons for the six months ended June 30, 2009, reflecting the increase in volume associated with the purchase of the customer contracts from ESOI in June 2009 and the increase in steel production that began in the second quarter of 2009 and continued into 2010. According to data from the American Iron & Steel Institute, reported steel production for the six months ended June 30, 2010 increased 63.4% from the six months ended June 30, 2009.
     Cost of sales (excluding depreciation and amortization). Consolidated cost of sales increased $47.7 million, or 43.6%, to $157.0 million for the six months ended June 30, 2010, compared to $109.3 million for the six months ended June 30, 2009. The increase includes a $31.1 million increase in cost of sales for Horsehead and $16.6 million in cost of sales related to INMETCO. As a percentage of consolidated net sales, consolidated cost of sales was 80.3% for the six months ended June 30, 2010, compared to 125.0% for the six months ended June 30, 2009.

     Cost of sales related to Horsehead increased $31.1 million, or 28.4%, to $140.4 million for the six months ended June 30, 2010, compared to $109.3 million for the six months ended June 30, 2009. As a percentage of net sales related to Horsehead, cost of sales was 82.7% for the six months ended June 30, 2010, compared to 125.0% for the six months ended June 30, 2009. The change in percentage reflects the net effect of changes in the average LME zinc prices on our net sales and cost of sales. Changes in the average LME zinc price are restricted to the purchased feed component of our cost of sales; therefore any changes in the average LME zinc price have a smaller effect on our cost of sales than on our net sales.
     The cost of zinc material and other products sold increased $24.3 million, or 23.4% to $128.0 million for the six months ended June 30, 2010, compared to $103.7 million for the six months ended June 30, 2009. The increase was primarily the result of a $21.5 million increase in shipment volume across all major product lines, a $10.8 million increase in the cost of products shipped and an $8.0 million decrease in recycling and other costs. The increases reflect higher feed costs and higher conversion costs for the six months ended June 30, 2010 compared to the six months ended June 30, 2009. Purchased feed costs were increased by $18.8 million, reflecting both the higher LME average zinc price as well as a 51.5% increase in the number of tons of purchased feed consumed.
     Our conversion costs were $14.5 million higher in the six months ended June 30, 2010 than in the six months ended June 30, 2009. The increase reflects an $8.1 million increase in utility costs, a $3.9 million increase in labor costs and a $2.6 million increase in maintenance and supplies costs. These increases were driven primarily by higher production levels for the six months ended June 30, 2010 as compared to the six months ended June 30, 2009 in response to the gradual economic recovery that began late in 2009 and continued into 2010. The increase in production levels for the six months ended June 30, 2010 compared to the six months ended June 30, 2009 more than offset the increase in conversion costs on a per ton basis. Our conversion cost per ton decreased for the six months ended June 30, 2010 compared to the six months ended June 30, 2009.
     The cost of EAF dust services increased $6.8 million, or 121.6%, to $12.4 million for the six months ended June 30, 2010, compared to $5.6 million for the six months ended June 30, 2009 primarily reflecting the 64.6% volume increase of EAF dust received partially offset by an increase in transportation costs.
     Depreciation and amortization. Consolidated depreciation and amortization expense increased $1.6 million, or 21.8%, to $8.8 million for the six months ended June 30, 2010, compared to $7.2 million for the six months ended June 30, 2009. The increase related to Horsehead was $0.3 million and the increase related to INMETCO was $1.3 million.
     Selling, general and administrative expenses. Selling, general and administrative expenses increased $2.0 million to $9.7 million for the six months ended June 30, 2010, compared to $7.7 million for the six months ended June 30, 2009. The increase reflects primarily an increase in labor and benefit costs of $0.8 million partially offset by a $0.5 million decrease in bad debt expense. Selling, general and administrative expenses relating to INMETCO were $1.2 million.
     Interest expense. Interest expense decreased $0.4 million to $0.6 million for the six months ended June 30, 2010, compared to $1.0 million for the six months ended June 30, 2009. The decrease largely reflects a $0.7 million reduction in expenses related to the credit facility we cancelled in December, 2009, partially offset by a $0.4 million increase in accretion expense associated with the liability we incurred to purchase the ESOI EAF dust contracts in June of 2009.
     Interest and other income. Interest and other income increased $0.3 million for the six months ended June 30, 2010. The increase primarily reflects a $0.1 million increase in interest earned on excess cash during the first six months of 2010 and $0.2 million in other income related INMETCO.
     Income tax provision (benefit). Our income tax provision was $7.5 million for the six months ended June 30, 2010, compared to a benefit of $(13.4) million for the six months ended June 30, 2009. Our estimated annual effective tax rate for 2010 changed from 35.9% as of March 31, 2010 to 37.6% as of June 30, 2010. The change in the annual rate primarily reflects the combined effect of a reduction in our projected pre-tax income for 2010, brought about by a reduction in the expected price of zinc, and the tax effect of temporary differences. Our effective tax rate was 35.8% for the six months ended June 30, 2009.
     Net income. For the reasons stated above, our net income was $12.5 million for the six months ended June 30, 2010, compared to a net loss of $(24.1) million for the six months ended June 30, 2009.

Liquidity and Capital Resources
     We finance our operations, capital expenditures and debt service primarily with funds generated by our operations. We believe the combination of our cash balance, our cost reduction initiatives, our hedging positions, and our cash generated from operations will be sufficient to satisfy our liquidity and capital requirements for the next twelve months. Our cash is not restricted with the exception of $31.3 million related to the following three items. The first is the New Markets Tax Credit (“NMTC”), the second is the financial assurance associated with the ESOI customer contracts purchased by us, and the third is the collateral for our letters of credit, all of which are described in our annual report on Form 10-K for the fiscal year ended December 31, 2009, which was filed with the SEC on March 16, 2010. We believe our cash balance is sufficient to satisfy our liquidity and capital requirements for the next twelve months. We further believe we could reduce our capital requirements, if necessary, to maintain liquidity. Our ability to continue to fund these requirements may be affected by industry factors, including LME zinc prices, and by general economic, financial, competitive, legislative, regulatory and other factors discussed herein, including the impact on our operating results of the explosion that occurred at our Monaca, Pennsylvania facility, or in the materials incorporated herein by reference.
June 30, 2010
     Our balance of cash and cash equivalents at June 30, 2010, excluding $31.3 million of restricted cash, was $82.8 million, a $12.7 million decrease from the December 31, 2009 balance of $95.5 million. Cash and cash equivalents are concentrated in two U.S. banks. In 2009 we invested in certificates of deposit and other short term investments. The funds invested in certificates of deposit on December 31, 2009 matured in January 2010 and were invested in a money market demand account, bringing the balance to $50.3 million as of March 31, 2010. That balance was subsequently transferred to our cash account. The funds we had invested in the government money market fund on December 31, 2009 matured in January 2010.
Cash Flows from Operating Activities
     Our operations provided a net $16.8 million in cash for the six months ended June 30, 2010, reflecting the gradual improvement in the overall economy as well as the generally higher LME average prices of zinc and nickel during the period. The improving economy also contributed also to the increase in accounts receivable and inventory during the period.
     Our investment in working capital was $140.9 million at June 30, 2010 and $143.5 million at December 31, 2009. The $12.7 million decrease in our cash and cash equivalents was largely offset by increases in our accounts receivable, inventory, and prepaid expenses and other current assets, which include the fair value of our open hedge positions. The post closing adjustments associated with our purchase of INMETCO reduced working capital by $0.9 million during the first quarter of 2010. The increase in our accounts receivable reflects higher sales volumes resulting from the strengthening economy. The increase in our inventories reflects cost and volume increases of 32% and 56%, respectively, associated with our zinc products finished goods inventory.
     Our zinc put option open positions include a favorable non-cash fair value adjustment of $1.9 million. We purchased the put options in 2009 and 2010 to protect our cash flows from declines in the LME price of zinc. The options settle monthly. We are entitled to receive the amount, if any, by which the option strike price, set at $0.65 per pound, exceeds the average LME price of zinc during the preceding month. During the six months ended June 30, 2010, the average LME zinc price exceeded the strike price, consequently the options settled with no payment due to us.
Cash Flows from Investing Activities
     Cash used in investing activities was $29.3 million for the six months ended June 30, 2010, of which $19.6 million related to the construction of the two kilns in South Carolina. The first kiln commenced operation in mid-April of 2010. The start date of the second kiln will be determined by market conditions. We funded capital expenditures with cash on hand. Additionally, we made payments totaling $4.6 million representing the remaining purchase price of INMETCO.
Off-Balance Sheet Arrangements
     Our off-balance sheet arrangements include operating leases and letters of credit. As of June 30, 2010, we had letters of credit outstanding in the amount of $20.4 million to collateralize self-insured claims for workers’ compensation and other general insurance claims and closure bonds for our two facilities in Pennsylvania. These letters of credit are collateralized by $21.4 million in restricted cash.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
     In the ordinary course of our business, we are exposed to potential losses arising from changes in interest rates and the prices of zinc, natural gas and coal. We have historically used derivative instruments, such as swaps, put options and forward purchase contracts to manage the effect of these changes. When we use forward contract hedging instruments to reduce our exposure to rising energy prices, we are limited in our ability to take advantage of future reductions in energy prices, because the hedging instruments require us to exercise the hedging instrument at the settlement date regardless of the market price at the time. We have also used put options to reduce our exposure to future declines in zinc prices. We have entered into arrangements hedging a portion of our exposure to future changes in the price of zinc through 2011.
     Our risk management policy seeks to meet our overall goal of managing our exposure to market price risk, particularly risks related to changing zinc prices. All derivative contracts are held for purposes other than trading and are used primarily to mitigate uncertainty and volatility of expected cash flow and cover underlying exposures. We are exposed to losses in the event of non-performance by the counter-parties to the derivative contracts discussed below, as well as any similar contracts we may enter into in future periods. Counter-parties are evaluated for creditworthiness and risk assessment both prior to our initiating contract activities and on an ongoing basis.
Commodity Price Risk
     Our business consists principally of the sale of zinc and nickel-based products. As a result, our results of operations are subject to risk of fluctuations in the market price of zinc and nickel. Because our finished products are generally priced based on a spread to the price of zinc on the LME, our sales revenues are impacted significantly by changes in the market price of zinc. Changes in zinc prices will also impact our ability to generate revenue from our EAF recycling operations as well as our ability to procure raw materials. In addition, we consume substantial amounts of energy in our zinc production and EAF dust recycling operations, and therefore our cost of sales is vulnerable to changes in prevailing energy prices, particularly natural gas, coke and coal.
     In 2008, we purchased put options for 2009 for a financial hedge for approximately 90,000 tons of zinc (7,500 tons monthly) or approximately 60% of our anticipated 2009 sales volume. The cost of these options was approximately $10.5 million. The options settled on a monthly basis, and in each settlement we were entitled to receive the amount, if any, by which the option strike price, set at $0.50 per pound for the duration of 2009, exceeded the average LME price for zinc during the preceding month. In 2009, we purchased put options for approximately 100,000 tons of zinc for 2010 at a cost of $5.3 million. In April of 2010, we purchased put options for approximately 25,000 tons of zinc for 2011 at a cost of $0.9 million. The options for both years have a strike price of $0.65 per pound. At the time of the purchases, the options for 2010 represented approximately 80% of our anticipated sales volume for 2010. The options are included in “Prepaid expenses and other current assets” in our consolidated financial statements.
     We are party to contracts for the purchase and delivery of the coal requirements for our power plant in Monaca through 2010. Each year, we enter into contracts for the forward purchase of natural gas to cover the majority of natural gas requirements in order to reduce our exposure to the volatility of natural gas prices.
Item 4. Controls and Procedures.
     (a) Evaluation of disclosure controls and procedures.
     Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are effective to ensure that information required to be disclosed by us in reports that we file or submit under

24


Table of Contents

the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures were effective as of June 30, 2010.
     (b) Changes in internal control over financial reporting
     During the quarter ending June 30, 2010, there was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that in our management’s judgment has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
     On December 31, 2009, we acquired INMETCO. We are currently in the process of evaluating the acquired business’ internal controls and the impact of the acquisition on our internal control over financial reporting.

PART II—OTHER INFORMATION
Item 1. Legal Proceedings.
     We are party to various litigation, claims and disputes, including labor regulation claims and OSHA and environmental regulation violations, some of which are for substantial amounts, arising in the ordinary course of business. While the ultimate effect of such actions cannot be predicted with certainty, we expect that the outcome of these matters will not result in a material adverse effect on our business, financial condition or results of operations.
Item 1A. Risk Factors.
     Our Risk Factors are discussed in our Annual Report on Form 10-K for the year ended December 31, 2009, which was filed with the SEC on March 16, 2010. We have updated our risk factors as stated below to address the effect on our business of the explosion that occurred at our Monaca, Pennsylvania facility on July 22, 2010.
  Equipment or power failures, delays in deliveries or catastrophic loss at any of our facilities, such as experienced in the explosion at our Monaca, Pennsylvania facility that occurred on July 22, 2010, could prevent us from meeting customer demand, reduce our sales, increase our costs and/or negatively impact our results of operations.
     An interruption in production or service capabilities at any of our production facilities as a result of equipment or power failure or other reasons, such as the explosion at our Monaca, Pennsylvania facility, could limit our ability to deliver products to our customers, reducing our net sales and net income, increasing our costs and potentially damaging relationships with our customers. Any significant delay in deliveries to our customers could lead to increased returns or cancellations, damage to our reputation and/or permanent loss of customers. Any such production stoppage or delay could also require us to make unplanned capital expenditures, which together with reduced sales and increased costs, could adversely affect our results of operations.
     Furthermore, because many of our customers are, to varying degrees, dependent on deliveries from our facilities, customers that have to reschedule their own production due to our missed deliveries could pursue financial claims against us. Our facilities are also subject to the risk of catastrophic loss due to unanticipated events such as fires, the explosion at our Monaca, Pennsylvania facility, adverse weather conditions or other events. We have experienced, and may experience in the future, periods of reduced production as a result of repairs that are necessary to our kiln, smelting and refinery operations. If any of these events occur in the future, they could have a material adverse effect on our business, financial condition or results of operations. Our insurance policies may not cover all of our losses and we could incur uninsured losses and liabilities arising from, among other things, loss of life, physical damage, business interruptions and product liability including as a result of the explosion at our Monaca, Pennsylvania facility.
