Overview

      Century Aluminum Company (“Century” or the “Company”) is a leading producer of primary aluminum. The Company’s facilities produce value-added and standard-grade primary aluminum products. Century is the second largest primary aluminum producer in the United States, behind Alcoa Inc. (together with its affiliates, “Alcoa”). Century produced approximately 1.2 billion pounds of primary aluminum in 2004 with net sales of $1,060.7 million. In April 2004, the Company acquired Nordural, an Icelandic facility which is the Company’s first facility located outside of the United States. The Company currently has an annual primary aluminum production capacity of approximately 1.4 billion pounds of primary aluminum with pro forma net sales of $1,099.1 million for the year ended December 31, 2004.

      The Company currently owns:

      For a description of these facilities, see Part I, Item 1, “Facilities and Production.”

      The Company’s strategic objectives are to grow its aluminum business by pursuing opportunities to acquire primary aluminum reduction facilities that offer favorable investment returns and lower its per unit

production costs; diversifying the Company’s geographic presence; and pursuing opportunities in bauxite mining and alumina refining. To date, the Company’s growth activities have included:

      For a description of these acquisitions, see Part I, “Acquisitions.”

Acquisitions

      The Gramercy Acquisition. On October 1, 2004, the Company and Noranda Finance Inc., through 50/50 joint venture companies, acquired an alumina refinery in Gramercy, Louisiana and related bauxite mining assets in Jamaica (collectively, the “Gramercy assets.”) from Kaiser Aluminum & Chemical Company (“Kaiser”). The purchase price for the Gramercy assets was $23.0 million, subject to working capital adjustments. The Company paid one-half, or $11.5 million of the unadjusted purchase price, which was funded with available cash. Noranda paid the remaining $11.5 million.

      Nordural Acquisition. On April 27, 2004, the Company completed the acquisition of Nordural hf (now known as Nordural ehf.) (“Nordural”) from Columbia Ventures Corporation, a privately-owned investment company headquartered in Vancouver, Washington. Nordural is an Icelandic company that owns and operates the Nordural facility, a primary aluminum reduction facility located in Grundartangi, Iceland, approximately 25 miles northwest of Reykjavik, Iceland’s capital. The Company paid $195.3 million, which was paid with a portion of the proceeds of the Company’s public equity offering of 9,000,000 shares of its common stock in April 2004 at a price to the public of $24.50 per share.

      Hawesville’s Remaining 20% Interest. On April 1, 2003, the Company acquired the remaining 20% interest in the Hawesville facility owned by Glencore for a purchase price of $99.4 million. The Company also assumed Glencore’s pro rata share of the industrial revenue bonds and post-closing payments to Southwire, which are described below. As a result of this acquisition, the Company owns all of the Hawesville facility. The Company financed a portion of the purchase price by issuing a six-year $40.0 million note to Glencore bearing interest at a rate of 10% per annum (the “Glencore Note”). The Company repaid $26.0 million of

principal under the Glencore Note in the fourth quarter of 2003, and the balance of $14.0 million in April 2004.

      80% Interest in the Hawesville Facility. Effective April 1, 2001, the Company completed the acquisition of the Hawesville facility from Southwire Company (“Southwire”), a privately held wire and cable manufacturing company. Concurrently with the acquisition, the Company effectively sold a 20% interest in the Hawesville facility to Glencore. As part of the acquisition, the Company and Glencore each assumed a pro rata share of industrial revenue bonds related to the Hawesville facility in the principal amount of $7.8 million and post-closing payments to Southwire of up to $7.0 million if the market price of primary aluminum exceeds specified levels during any of the seven years following closing. The entire $7.0 million will become due in April 2005.

Facilities and Production

      The Nordural facility is owned by Nordural ehf, a wholly-owned indirect subsidiary of the Company. The Nordural facility is located in Grundartangi, Iceland, approximately 25 miles northwest of Reykjavik, Iceland’s capital. Built in 1998 and expanded in 2001, the Nordural facility is the Company’s most recently constructed and lowest cost facility. It has an annual production capacity of approximately 198 million pounds, which will increase by up to 269 million pounds to approximately 467 million pounds upon completion of an ongoing expansion of the facility, with potential for further expansion to 573 million pounds of annual production capacity. The Nordural facility is situated on two hundred acres leased from the Government of Iceland and consists of an aluminum reduction plant with two potlines and casting equipment used to cast molten aluminum into ingot.

      The following table shows primary aluminum shipments from the Nordural facility during each of the periods indicated:

Nordural Facility Primary Aluminum Shipments

      The Nordural facility operates under various long-term agreements with the Government of Iceland. These agreements include (i) an investment agreement which establishes Nordural’s tax status and the Government’s obligations to grant certain permits, (ii) a reduction plant site agreement by which Nordural leases the property through 2020, subject to renewal at its option; and (iii) a harbor agreement by which Nordural is granted access to the port at Grundartangi. In connection with the expansion of the Nordural facility, Nordural has entered into amendments to the investment agreement and the reduction plant site agreements with the Government of Iceland.

      The Company has commenced work on an expansion of the Nordural facility that will increase its annual production capacity to approximately 467 million pounds. As currently planned, the expansion will add 269 million pounds to the Nordural facility’s annual production capacity. The expansion is projected to be completed by late-2006 and is expected to cost approximately $454 million. Following completion of the expansion, Nordural will have all the infrastructure and support facilities necessary for further expansion to 573 million pounds of annual production capacity.

      On February 10, 2005, Nordural executed agreements and documents related to a $365.0 million senior term loan facility arranged by Landsbanki Islands hf. and Kaupthing Bank hf, which funded on February 15,

2005. See Part II, Item 7, “Management’s Discussion and Analysis — Recent Developments — Nordural’s New Term Loan Facility.” Amounts borrowed under Nordural’s new term loan facility were used to refinance debt under Nordural’s prior term loan facility. In addition, the new term loan facility will be used to finance a portion of the costs associated with the ongoing expansion of the Nordural facility and for Nordural’s general corporate purposes. The Company expects to fund the remaining costs of the expansion capacity with operating cash flow generated by its operations, including the operations of the Nordural facility.

      Nordural is party to a long-term alumina tolling contract with a subsidiary of BHP Billiton which expires December 31, 2013. Under this contract, which is for virtually all of the Nordural facility’s existing production capacity, Nordural receives an LME-based fee for the conversion of alumina, supplied by BHP Billiton, into primary aluminum. Nordural has entered into a ten-year alumina tolling contract with Glencore for 198 million pounds of the expansion capacity at the Nordural facility. The fee Nordural will receive under that contract will also be LME-based.

      The Nordural facility purchases power from Landsvirkjun, a power company jointly owned by the Republic of Iceland and two Icelandic municipal governments, under a long-term contract due to expire in 2019. The power delivered to the Nordural facility under its current contract is from hydroelectric and geothermal sources, competitively-priced and renewable sources of power for the Nordural facility, at a rate based on the LME price for primary aluminum. In connection with the expansion, Nordural entered into an agreement with Hitaveita Suóurnesja hf. (“Sudurnes Energy”) and Orkuveita Reykjavíkur (“Reykjavik Energy”) for the supply of the additional power required for the 269 million pounds of expansion capacity. Under this agreement, Nordural will be required to take or pay for a significant percentage of the power to be supplied beginning a specified period after signing (subject to extension for agreed upon events), even if the Nordural expansion is not completed. The agreement also includes power for an additional 18 million pounds of capacity, upon satisfaction of certain conditions, including the completion of a power transmission agreement. With the additional 18 million pounds of capacity, the total annual production capacity of the Nordural facility would increase to 485 million pounds by late 2006. A decision on the additional 18 million pounds of capacity is expected in early 2005. Under the terms of Nordural’s energy contracts with Sudurnes Energy and Reykjavik Energy, the rate for the power supplied for the expansion capacity will be LME-based. Landsvirkjun has agreed on a best commercial efforts basis to provide backup power to Nordural if Sudurnes Energy and Reykjavík Energy are unable to meet the obligations of their contract to provide power for the Nordural expansion. The Company’s plans to further increase the size of the expansion project beyond 485 million pounds will depend on its ability to enter into certain key contracts for that capacity. The Company is in discussions for the supply of electric power to support the further expansion of the Nordural facility to the full 573 million pounds of annual production capacity.

      Nordural has a contract for the supply of anodes for its existing capacity which expires in 2013. The Company is currently exploring options for the supply of anodes for the expansion capacity and does not currently believe the price to be paid for those anodes will be materially different than under Nordural’s current arrangement.

      The Hawesville facility is owned by NSA Ltd. and Hancock Aluminum, LLC and operated by Century Aluminum of Kentucky, LLC, each a wholly-owned direct or indirect subsidiary of the Company. The Hawesville facility, strategically located adjacent to the Ohio River near Hawesville, Kentucky, began operations in 1970 and has an annual production capacity of 538 million pounds.

      The Hawesville facility’s original four potlines have an annual production capacity of approximately 426 million pounds and are specially configured and operated so as to produce high purity primary aluminum. The average purity level of primary aluminum produced by these potlines is 99.9%, compared to standard-purity aluminum which is approximately 99.7%. This high purity primary aluminum provides the conductivity required by Hawesville’s largest customer, Southwire, for its electrical wire and cable products as well as for certain aerospace applications. A fifth potline added in 2001 has an annual capacity of approximately 112 million pounds of standard-purity aluminum. See “Sales and Distribution — The Hawesville Facility.”

      The Hawesville facility produces primary aluminum in molten, ingot and sow form. The following table shows primary aluminum shipments from the Hawesville facility during each of the periods indicated:

Hawesville Facility Primary Aluminum Shipments

      The alumina used by the Hawesville facility is purchased under a supply agreement with Gramercy Alumina LLC (“GAL”), which was entered into on November 2, 2004 in connection with the Gramercy acquisition. GAL, a joint venture company owned 50/50 by Century and Noranda owns and operates the Gramercy alumina refinery. . See “— Facilities and Production — The Gramercy Facility.” This supply agreement runs through December 31, 2010 and replaces the previous supply agreement with Kaiser. The price the Company pays for alumina used by the Hawesville facility is now based on the cost of alumina production. Under its previous agreement with Kaiser, the Company purchase alumina at prices based on the London Metals Exchange (“LME”) price for primary aluminum.

      The Hawesville facility purchases all of its power from Kenergy Corp. (“Kenergy”), a local retail electric cooperative, under a power supply contract that expires at the end of 2010. Kenergy acquires most of the power it provides to the Hawesville facility from a subsidiary of LG&E Energy Corp., with delivery guaranteed by LG&E. The Hawesville facility currently purchases all of its power from Kenergy at fixed prices. Approximately 27% of the Hawesville facility’s power requirements are unpriced for the period from 2006 to 2010.

      The Ravenswood facility is owned and operated by the Company’s subsidiary, Century Aluminum of West Virginia, Inc. (“Century of West Virginia”). Built in 1957, the Ravenswood facility operates four potlines with an annual production capacity of 375 million pounds. The facility is strategically located adjacent to the Ohio River in Ravenswood, West Virginia.

      The Ravenswood facility produces molten aluminum that is delivered to Pechiney’s adjacent fabricating facility and standard-grade ingot that Century sells in the marketplace. See “Sales and Distribution — The Ravenswood Facility.”

      The following table shows primary aluminum shipments from the Ravenswood facility during each of the periods indicated:

Ravenswood Facility Primary Aluminum Shipments

      Since January 1, 2002, the alumina used at the Ravenswood facility has been supplied by Glencore under a five-year contract at a variable price determined by reference to the LME price for primary aluminum. The Company purchases the electricity used at the Ravenswood facility under a fixed-price power supply contract with Ohio Power, a subsidiary of American Electric Power, which runs through December 31, 2005. On February 18, 2005, Century of West Virginia signed an agreement with Appalachian Power Company for the supply of electricity to the Ravenswood facility beginning January 1, 2006. The agreement has an initial term of two years and continues thereafter until Century gives 12 months’ notice of cancellation. Appalachian Power has filed a petition with the Public Services Commission of West Virginia (“PSC”) seeking affirmation of its authorization to provide service to the Ravenswood facility. In 2000, the PSC found that the Ravenswood facility was in Appalachian Power’s service territory and had jurisdiction over the provision of service. The agreement will become effective unless the PSC fails to affirm its previous findings. Power under the new agreement is priced under an Appalachian Power tariff.

      The Mt. Holly facility, located in Mt. Holly, South Carolina, was built in 1980 and is the most recently constructed aluminum reduction facility in the United States. The facility consists of two potlines with a total annual production capacity of 489 million pounds and casting equipment used to cast molten aluminum into standard-grade ingot, extrusion billet and other value-added primary aluminum products. Value-added primary aluminum products are sold at higher prices than standard-grade primary aluminum. The Company’s 49.7% interest represents 243 million pounds of the facility’s production capacity.

      Century’s interest in the Mt. Holly facility is held through its subsidiary, Berkeley Aluminum, Inc. (“Berkeley”). Under the Mt. Holly ownership structure, the Company holds an undivided 49.7% interest in the property, plant and equipment comprising the aluminum reduction operations at the Mt. Holly facility and an equivalent share in the general partnership responsible for the operation and maintenance of the facility. Alcoa owns the remaining 50.3% interest in the Mt. Holly facility and an equivalent share of the operating partnership. Under the terms of the operating partnership, Alcoa is responsible for operating and maintaining the facility. Each owner supplies its own alumina for conversion to primary aluminum and is responsible for its proportionate share of operational and maintenance costs.

      The following table shows the Company’s primary aluminum shipments from the Mt. Holly facility during each of the periods indicated:

Mt. Holly Facility Primary Aluminum Shipments

      Glencore supplies all of the Company’s alumina requirements for the Mt. Holly facility under contracts which expire December 31, 2006 and January 31, 2008. The price under both contracts is determined by reference to the quoted LME price for primary aluminum.

      The Mt. Holly facility purchases all of its power requirements from the South Carolina Public Service Authority (also called “Santee Cooper”), under a contract that runs through 2015. Power delivered through 2010 will be priced at rates fixed under currently published schedules, subject to adjustments for fuel costs. Rates for the period 2011 through 2015 will be as provided under then-applicable schedules.

      On October 1, 2004, the Company and Noranda Finance Inc., through 50/50 joint venture companies, acquired an alumina refinery in Gramercy, Louisiana and related bauxite mining assets in Jamaica (collectively, the “Gramercy assets”) from Kaiser Aluminum & Chemical Company (“Kaiser.”) The Gramercy assets were acquired pursuant to the terms of an Asset Purchase Agreement, dated May 17, 2004, among Gramercy Alumina LLC, St. Ann Bauxite Limited, Kaiser, and Kaiser Bauxite Company. Gramercy Alumina LLC (“GAL”) and St. Ann Bauxite Limited (“SABL”) are joint venture companies formed by Century and Noranda to separately acquire the Gramercy plant and the bauxite mining assets, respectively.

      The purchase price for the Gramercy assets was $23 million, subject to working capital adjustments. The Company paid one-half, or $11.5 million of the unadjusted purchase price, which the Company funded with available cash. Noranda paid the remaining $11.5 million. The Company accounts for its investment in the Gramercy assets using the equity method of accounting. Kaiser sold the Gramercy assets with the approval of the United States Bankruptcy Court for the District of Delaware as part of its plan to emerge from Chapter 11 bankruptcy.

Alumina Refining Operations

      The alumina refinery in Gramercy is owned by GAL, a Delaware limited liability company. The Gramercy plant began operations in 1959 and consists of a production facility, a powerhouse for steam and electricity production, a deep water dock and a barge loading facility. Extensive portions of the Gramercy plant were rebuilt and modernized between 2000 and 2002.

      The Gramercy plant currently produces alumina at a capacity rate of approximately 1.2 million metric tons per year, consisting of approximately 80% smelter grade alumina (“SGA”), and 20% alumina hydrate, or chemical grade alumina (“CGA”).

      The following table shows annual production from the Gramercy plant facility during each of the periods indicated:

Gramercy Plant Alumina Production

      The Company expects production at the Gramercy plant to remain at or near capacity for the foreseeable future.

      Bauxite is the principal raw material used in the production of alumina, and natural gas is the principal energy source. The Gramercy plant purchases all of its bauxite requirements from the affiliated Jamaican bauxite mining operations described below under a contract that expires at the end of 2010 at a price that is fixed through 2005. The Gramercy plant purchases its natural gas requirements at market prices under short-term agreements with local suppliers.

Bauxite Mining Operations

      The bauxite mining assets were acquired by SABL, a newly-established Jamaican limited liability company jointly owned by Century and Noranda. The bauxite mining assets are comprised of: (i) a concession from the Government of Jamaica (“GOJ”) to mine bauxite in Jamaica (the “mining rights,”) and (ii) a 49% interest in a Jamaican partnership that owns certain mining assets in Jamaica (the “mining assets.”) The GOJ owns the remaining 51% interest in the partnership. Following the acquisition, SABL and the GOJ established a new partnership to hold the mining assets and to conduct mining and related operations pursuant to the mining rights. The mining assets consist primarily of rail facilities, other mobile equipment, dryers, and loading and dock facilities. The age and remaining lives of the mining assets vary and they may be repaired or replaced from time to time as part of SABL’s ordinary capital expenditure plan. Under the terms of the mining rights, SABL manages the operations of the new partnership, pays operating costs and is entitled to all of its bauxite production. The GOJ receives: (i) a royalty based on the amount of bauxite mined, (ii) an annual “asset usage fee” for the use of the GOJ’s 51% interest in the mining assets, and (iii) certain fees for lands owned by the GOJ that are covered by the mining rights. SABL also pays to the GOJ customary income and other taxes and fees pursuant to an Establishment Agreement with the GOJ that establishes the fiscal regime for SABL through December 2005. A production levy normally applicable to bauxite mined in Jamaica has been waived for SABL through December 2007. If the levy is subsequently assessed on bauxite produced by SABL, the Establishment Agreement provides that certain payments to the GOJ will be reduced and SABL and GOJ will negotiate amendments to SABL’s fiscal regime in order to mitigate the effects of the levy.

      Mining Rights. Under the terms of the mining rights, SABL mines the land covered by the mining rights and the GOJ retains surface rights and ownership of the land. The GOJ granted the mining rights and entered into other agreements with SABL for the purpose of ensuring the Gramercy plant will have sufficient reserves to meet its annual alumina requirements and existing or contemplated future obligations under third party contracts. Under the mining rights, SABL is entitled to mine 4.5 million dry metric tons, (“DMT”), of bauxite on specified lands annually through September 30, 2030. The GOJ is required to provide additional land if the land covered by the mining rights does not contain sufficient levels of commercially exploitable bauxite. SABL is responsible for reclamation of the land that it mines. In addition, SABL assumed reclamation obligations related to prior operations of approximately $9 million.

SABL Bauxite Production

      The following table shows annual production from the Jamaican mining operations for the periods indicated:

      Provided existing customers continue to purchase bauxite at previous levels, SABL is expected to produce approximately 4.0 million DMT in 2005 and if current market conditions continue, will proceed with raising production to fully use its annual bauxite mining rights.

      SABL has various short-term agreements with third parties for the supply of fuel oil, diesel fuel, container leasing and other locally provided services.

Industry Overview

      The most commonly used bench mark for pricing primary aluminum is the price for aluminum transactions quoted on the LME. The LME price, however, does not represent the actual price paid for all aluminum products. For example, products delivered to U.S. customers are often sold at a premium to the LME price, typically referred to as the U.S. Midwest Market Price. Over the last ten years through December 2004, the average monthly Midwest premium has ranged from $0.021 to $0.077 per pound. In addition, premiums are charged for adding certain alloys to aluminum for use in specific applications and for casting aluminum into specific shapes, such as extrusion billet or rolling slab.

      During 2002, global demand increased modestly, however supply growth matched the increase and the market price for primary aluminum declined. In 2003, global demand for aluminum increased approximately 7.7% to 60.0 billion pounds in 2003, but global aluminum supply did not keep pace as global aluminum production increased only approximately 7.1% to 61.5 billion pounds. During 2004, global demand increased by 9.0% to 66.3 billion pounds and LME inventories declined 54% from 1.5 million metric tons to 695,000 metric tons. The primary aluminum industry is currently experiencing a period of strong prices based on favorable production and consumption trends. Spot aluminum prices, as quoted on the LME, remain above the five and ten-year averages. The key factors in the current strong pricing environment are: (i) strengthening global demand for aluminum driven by the global economic recovery; (ii) strong demand growth in China; (iii) a tightening market for alumina, the major raw material input for aluminum, that has resulted in a rapid escalation of alumina prices; and (iv) the recent weakening of the U.S. dollar. The average LME cash price for aluminum was $0.78, $0.65, and $0.61 per pound for the years ended December 31, 2004, 2003 and 2002, respectively.

Sales and Distribution

      The majority of the products produced at the Company’s facilities are sold to a limited number of customers. The Company derived a combined total of approximately 76.3% of its 2004 consolidated sales from Pechiney, Southwire, BHP Billiton and Glencore, Century’s four largest customers. Out of total revenues of $1,060.7 million for 2004, sales to Pechiney represented $301.0 million, or 28.4% of Century’s total revenues, sales to Southwire represented $258.3 million, or 24.4% of total revenues, sales to Glencore represented $163.2 million, or 15.4% of total revenues, and sales to BHP Billiton represented $85.5 million, or 8.1% of total revenues. The remaining $252.7 million, or 23.7% of Century’s total revenues, represented sales to approximately 50 customers.

      Nordural is party to a long-term alumina tolling contract with a subsidiary of BHP Billiton which is due to expire December 31, 2013. Under this contract, which is for virtually all of the Nordural facility’s existing production capacity, Nordural receives an LME-based fee for the conversion of alumina, supplied by BHP Billiton, into primary aluminum. Nordural has agreed to a 10-year alumina tolling contract with Glencore for 198 million pounds of the expansion capacity at the Nordural facility. The fee Nordural will receive under that contract will also be LME-based.

      Sales of primary aluminum to Southwire accounted for $258.3 million or 56.0% of Century’s revenues from the Hawesville facility in 2004. Sales to parties other than Southwire accounted for the remaining $203.0 million or 44.0% of the Company’s revenues from the Hawesville facility during 2004. In connection with the acquisition of the Hawesville facility in April 2001, the Company entered into a ten-year contract with Southwire (the “Southwire Metal Agreement”) to supply 240 million pounds of high-purity molten aluminum annually to Southwire’s wire and cable manufacturing facility located adjacent to the Hawesville facility. Under this contract, Southwire will also purchase 60 million pounds of standard-grade molten aluminum each year through March 2008. Southwire has an option to purchase an equal amount of standard-grade molten aluminum in each of the remaining three years. The price for the molten aluminum to be delivered to Southwire from the Hawesville facility is variable and determined by reference to the U.S. Midwest Market Price. This contract requires the Company to deliver molten aluminum, thereby reducing its casting and shipping costs. This agreement expires on March 31, 2011, and will automatically renew for additional five-year terms, unless either party provides 12 months’ notice that it has elected not to renew.

      Concurrently with its acquisition of the remaining interest in the Hawesville facility, the Company entered into a ten-year contract with Glencore (the “Glencore Metal Agreement”) under which Glencore agreed to purchase, beginning on January 1, 2004, 45.0 million pounds per year of the primary aluminum produced at the Ravenswood and Mt. Holly facilities, at a price determined by reference to the U.S. Midwest Market Price, subject to an agreed cap and floor as applied to the U.S. Midwest Premium.

      Sales of primary aluminum to Pechiney represented $249.9 million or 83.0% of revenues from the Ravenswood facility in 2004. Sales to parties other than Pechiney represented $51.1 million or 17.0% of Ravenswood’s revenues in 2004. Century has a contract with Pechiney (the “Pechiney Metal Agreement”) under which Pechiney purchases 23 to 27 million pounds, per month, of molten aluminum produced at the Ravenswood facility through July 31, 2007. This contract provides that it will be automatically extended through July 31, 2007 upon the Company’s entering into a new power contract for the Ravenswood facility through that date. On February 18, 2005, Century of West Virginia signed an agreement with Appalachian Power Company for the supply of electricity to the Ravenswood facility beginning January 1, 2006. The new power agreement has an initial term of two years and continues thereafter until Century gives 12 months’ notice of cancellation. Appalachian Power has filed a petition with the Public Services Commission of West Virginia (“PSC”) seeking affirmation of its authorization to provide service to the Ravenswood facility. In 2000, the PSC found that the Ravenswood facility was in Appalachian Power’s service territory and had jurisdiction over the provision of service. The new power agreement will become effective unless the PSC fails to affirm its previous findings. The price for primary aluminum delivered under the Pechiney Metal Agreement is variable and determined by reference to the U.S. Midwest Market Price. This contract requires the Company to deliver molten aluminum, thereby reducing its casting and shipping costs. Pechiney has the right, upon 12 months’ notice, to reduce its purchase obligations by 50% under this contract. Alcan acquired Pechiney in February 2004.

      Sales of primary aluminum to Glencore represented $109.5 million or 51.4% of Century’s revenues from the Mt. Holly facility in 2004. Sales to third parties other than Glencore represented $103.6 million or 48.6% of revenues from the Mt. Holly facility in 2004. Century had a contract to sell Glencore approximately 110 million pounds of primary aluminum produced at the Mt. Holly facility each year through December 31, 2009 (the “Original Sales Contract”). In January 2003, Century and Glencore agreed to terminate and settle the Original Sales Contract for the years 2005 through 2009 which had provided for fixed prices. At that time, the parties entered into a new contract (the “New Sales Contract”) that requires Century to deliver the same quantity of primary aluminum as did the Original Sales Contract for these years. The New Sales Contract provides for variable pricing determined by reference to the LME for the years 2005 through 2009. The price of primary aluminum delivered in 2004 remained fixed.

      Prior to the January 2003 agreement to terminate and settle the years 2005 though 2009 of the Original Sales Contract, the Company had been classifying and accounting for it as a normal sales contract under Statement of Financial Accounting Standard (“SFAS”) No. 133, “Accounting for Derivative Instruments and Hedging Activities.” A contract that is so designated and that meets other conditions established by SFAS No. 133 is exempt from the requirements of SFAS No. 133, although by its term the contract would otherwise be accounted for as a derivative instrument. Accordingly, prior to January 2003, the Original Sales Contract was recorded on an accrual basis of accounting and changes in the fair value of the Original Sales Contract were not recognized.

      According to SFAS No. 133, it must be probable that at inception and throughout its term, a contract classified as “normal” will not result in a net settlement and will result in physical delivery. In April 2003, the Company and Glencore net settled a significant portion of the Original Sales Contract, and it no longer qualified for the “normal” exception of SFAS No. 133. The Company marked the Original Sales Contract to current fair value in its entirety. Accordingly, in the first quarter of 2003 the Company recorded a derivative asset and a pre-tax gain of $41.7 million. Of the total recorded gain, $26.1 million related to the favorable terms of the Original Sales Contract for the years 2005 through 2009, and $15.6 million relates to the favorable terms of the Original Sales Contract for 2003 through 2004.

      The Company determined the fair value by estimating the excess of the contractual cash flows of the Original Sales Contract (using contractual prices and quantities) above the estimated cash flows of a contract based on identical quantities using LME-quoted prevailing forward market prices for aluminum plus an estimated U.S. Midwest premium adjusted for delivery considerations. The Company discounted the excess estimated cash flows to present value using a discount rate of 7%.

      On April 1, 2003, the Company received $35.5 million from Glencore, $26.1 million of which related to the settlement of the Original Sales Contract for the years 2005 through 2009, and $9.4 million of which represented the fair value of the New Sales Contracts, discussed below. The Company accounted for the unsettled portion of the Original Sales Contract (years 2003 and 2004) as a derivative and recognized period-to-period changes in fair value in current income. The Company accounts for the New Sales Contract as a derivative instrument under SFAS No. 133. The Company has not designated the New Sales Contract as “normal” because it replaces and substitutes for a significant portion of the Original Sales Contract which, after January 2003, no longer qualified for this designation. The $9.4 million initial fair value of the New Sales Contract is a derivative liability and represents the present value of the contract’s favorable term to Glencore in that the New Sales Contract excludes from its variable price an estimated U.S. Midwest premium, adjusted for delivery considerations. Because the New Sales Contract is variably priced, the Company does not expect significant variability in its fair value, other than changes that might result from the absence of the U.S. Midwest premium.

      Alumina Sales. Approximately 80% of Gramercy’s annual production capacity is supplied to the Company’s Hawesville and Noranda’s New Madrid primary aluminum production facilities. The Company’s Hawesville facility purchases virtually all of its alumina requirements from the Gramercy refinery. Prior to the

acquisition by GAL of the Gramercy plant, substantially all of the SGA produced at the Gramercy plant was sold to the Company and to Noranda under formula-priced alumina supply contracts calculated as a percentage of the LME price of primary aluminum. Following the acquisition, GAL sells SGA to the Company and to Noranda based on Gramercy’s production costs under alumina supply contracts due to expire on December 31, 2010. All of the CGA production is currently sold under existing short-term and long-term contracts with approximately 20 third party purchasers. GAL expects to continue CGA production and sales in order to optimize fixed costs.

      Bauxite Sales. Prior to the acquisition, Kaiser used approximately 60% of the bauxite produced by the bauxite mining assets to supply the alumina requirements at the Gramercy plant. The remaining 40% was sold to a third party alumina refinery in Texas. Concurrently with the acquisition by SABL and GAL of the Gramercy assets, SABL and GAL entered into a contract under which SABL will supply the Gramercy plant’s bauxite requirements through December 2010. The price for bauxite under the contract is fixed through December 31, 2005. SABL is currently negotiating a renewal of the third party agreement for the sale of its remaining bauxite production.

Pricing and Risk Management

      The Company’s operating results are sensitive to changes in the price of primary aluminum and the raw materials used in its production. As a result, Century attempts to mitigate the effects of fluctuations in primary aluminum and raw material prices through the use of various fixed-price commitments and financial instruments.

      The Company offers a number of pricing alternatives to its customers which, combined with Century’s metals risk management activities, are designed to lock in a certain level of price stability on its primary aluminum sales. Pricing of Century’s products is generally offered at an indexed or “market” price, where the customer pays an agreed-upon premium over the LME price or relative to other market indices.

      Substantially all of Nordural’s revenues are derived from a tolling arrangement whereby it converts alumina provided to it into primary aluminum for a fee based on the LME price for primary aluminum. Nordural’s revenues are subject to the risk of decreases in the market price of primary aluminum; however, because it produces primary aluminum under a tolling arrangement, Nordural is not exposed to increases in the price for alumina, the principal raw material used in the production of primary aluminum. In addition, under its current power contract, Nordural purchases power at a rate which is a percentage of the LME price for primary aluminum. By linking its most significant production cost to the LME price for primary aluminum, Nordural has a natural hedge against downswings in the market for primary aluminum; however, this hedge also limits Nordural’s upside as the LME price increases.

      The Company manages its exposure to fluctuations in the price of primary aluminum by selling primary aluminum at fixed prices for future delivery, through financial instruments, and by purchasing alumina under supply contracts with prices tied to the same indices as the Company’s aluminum sales contracts. To mitigate the volatility of the natural gas markets, the Company enters into fixed price financial purchase contracts. The Company’s metals and natural gas risk management activities are subject to the control and direction of senior management. These activities are regularly reported to the Board of Directors of Century. The Company’s risk management activities do not include trading or speculative transactions. See Part II, Item 7A, “Quantitative and Qualitative Disclosures about Market Risk.”

      Nordural does not currently have any material financial instruments to hedge commodity, currency or interest rate risk. Nordural is exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the euro and the Icelandic krona. Under its long-term tolling agreement with BHP Billiton, Nordural receives revenues denominated in U.S. dollars. Nordural’s labor costs are denominated in

Icelandic kronur and a portion of its anode costs are denominated in euros. As a result, an increase in the value of those currencies relative to the U.S. dollar would affect Nordural’s operating margins.

      SABL’s Jamaican bauxite mining operations do not currently have any material financial instruments to hedge commodity or currency risk. SABL’s Jamaican operations are exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the Jamaican dollar. Under its long-term bauxite agreement with the Gramercy plant, SABL receives revenues denominated in U.S. dollars. SABL’s labor costs are denominated in Jamaican dollars. As a result, an increase in the value of that currency relative to the U.S. dollar would affect SABL’s operating margins.

Competition

      The market for primary aluminum is world-wide, and demand for aluminum often varies widely from region to region. Aluminum production also takes place throughout the world. Aluminum competes with materials such as steel, plastic and glass, which may be substituted for aluminum in certain applications.

      In the United States, where most of the Company’s production capacity is located, the competitors are Alcoa, Alcan and a few smaller producers. At present, the U.S. demand for aluminum is robust, and U.S. production capacity has declined substantially over the past few years in the face of rising electrical power prices. As a consequence, much of the U.S. demand must be met by foreign production, and delivery premiums to the U.S. Midwest (reflecting cost of delivery to this market) have risen sharply. The geographic proximity of the Company’s plants to the U.S. Midwest provides the Company a competitive advantage over its off-shore competitors by enabling it to capture the premium without incurring the additional delivery costs.

      The Company also has certain advantages in product quality and customer service. Its Hawesville plant produces the high purity aluminum needed by Southwire’s next-door plant for the manufacture of electrical transmission lines. That high purity metal is delivered in molten form, a cost savings and competitive advantage to both parties. The Company’s Ravenswood plant also delivers molten metal to the adjacent Pechiney Rolled Product’s rolling mill, providing similar competitive advantages to the Company and Pechiney. And the Company’s versatile cast house at Mt. Holly permits it to focus its production at that plant almost exclusively on premium products.

      The current weak U.S. dollar also provides the Company with a competitive advantage. The LME aluminum price is a U.S. dollar price. The impact of the current weak U.S. dollar has the effect of improving the Company’s relative cost position versus off-shore competitors which must pay some or all of their production costs in currencies which have strengthened against the dollar.

      In addition, there is a duty payable by non-European producers for sales of aluminum into Europe. Icelandic aluminum producers are exempt from this duty. The alumina toll conversion agreements between the Company’s Nordural ehf subsidiary and third parties allow Nordural to receive portions of the premium received by those third parties as a result of these duty-free European sales.

Environmental Matters

      The Company is subject to various environmental laws and regulations. The Company has spent, and expects to spend, significant amounts for compliance with those laws and regulations. In addition, some of the Company’s past manufacturing activities have resulted in environmental consequences which require remedial measures. Under certain environmental laws which may impose liability regardless of fault, the Company may be liable for the costs of remediation of contaminated property, including its current and formerly owned or operated properties or adjacent areas, or for the amelioration of damage to natural resources. The Company believes, based on information currently available to its management, that its current environmental liabilities are not likely to have a material adverse effect on the Company. However, the Company cannot predict the requirements of future environmental laws and future requirements at current or formerly owned or operated properties or adjacent areas. Such future requirements may result in liabilities which may have a material adverse effect on the Company’s financial condition, results of operations or liquidity.

      The 1990 amendments to the Clean Air Act impose stringent standards on the aluminum industry’s air emissions. These amendments affect the Company’s operations as technology-based standards relating to reduction facilities and carbon plants have been instituted. Although the Company cannot predict with certainty how much it will be required to spend to comply with these standards, its general capital expenditure plan includes certain projects designed to improve its compliance with both known and anticipated air emissions requirements.

      The Company has incurred and in the future will continue to incur capital expenditures and operating expenses for matters relating to environmental control, remediation, monitoring and compliance. It is Century’s policy to accrue for costs associated with environmental assessments and remedial efforts when it becomes probable that the Company is liable and the associated costs can be reasonably estimated. The aggregate environmental-related accrued liabilities were $0.8 million at December 31, 2002, $0.7 million at December 31, 2003 and $0.6 million at December 31, 2004. All accrued amounts have been recorded without giving effect to any possible future recoveries. Century has planned capital expenditures related to environmental matters at all of its facilities of approximately $0.6 million in 2005, $1.3 million in 2006 and $0.4 million in 2007. In addition, the Company expects to incur operating expenses relating to environmental matters of approximately $9.9 million in 2005, $10.7 million in 2006 and $11.0 million in 2007. These amounts do not include any projected capital expenditures or operating expenses for matters relating to environmental control, remediation, monitoring and compliance for the Company’s joint venture interest in the Gramercy assets. See Item 1, “Business — Facilities and Production — The Gramercy Facility.” As part of the Company’s general capital expenditure plan, the Company also expects to incur capital expenditures for other capital projects that may, in addition to improving operations, reduce certain environmental impacts. With respect to ongoing environmental compliance costs, including maintenance and monitoring, the Company expense the costs when incurred.

      Nordural is subject to various Icelandic and other environmental laws and regulations. These laws and regulations are subject to change, which changes could result in increased costs. Operating in a foreign country exposes the Company to political, regulatory, currency and other related risks. The Nordural facility, built in 1998, uses technology currently defined to be “best available technology” under the European Union’s Integrated Pollution Prevention and Control Directive of 1996, or IPPC. The operational restrictions for the Nordural facility, as determined by the Icelandic Minister for the Environment, are set forth in the facility’s operating license. The license currently allows for both the facility’s current and planned expansion capacity.

      Under the Company’s agreement with Southwire to purchase the Hawesville facility, Southwire indemnified the Company against all on-site environmental liabilities known to exist prior to the closing of the acquisition and against risks associated with off-site hazardous material disposals which pre-dated the closing.

      Prior to the closing of the acquisition, the U.S. Environmental Protection Agency, or EPA, had issued a final record of decision, under the Comprehensive Environmental Response, Compensation and Liability Act, directing that certain response actions be taken at the Hawesville facility. By agreement, Southwire is to perform all obligations under the record of decision. The total costs for the obligations to be undertaken and paid for by Southwire relative to these liabilities are estimated under the record of decision to be $12.6 million, and the forecast of annual operating and maintenance costs is $1.2 million. Century Kentucky, LLC will operate and maintain the ground water treatment system required under the record of decision on behalf of Southwire, and Southwire will reimburse Century Kentucky, LLC for expenses that exceeds $0.4 million annually.

      If any on-site environmental liabilities arising from pre-closing activities at the Hawesville facility that were unknown on the date the acquisition closed but become known prior to March 31, 2007, the Company and Southwire will share the costs of remedial action pro rata depending on the year the liability is identified.

The Company will be responsible for all environmental liabilities which first become known on or after March 31, 2007 and any post-closing environmental liabilities that result from a change in laws.

      The Company acquired the Hawesville facility by purchasing all of the outstanding equity securities of Metalsco Ltd., a wholly-owned subsidiary of Southwire. Metalsco previously owned certain assets unrelated to the Hawesville plant’s operations. These assets owned by Metalsco were distributed to Southwire before the closing of the Hawesville acquisition. Southwire indemnified the Company for all liabilities related to these assets. Southwire also retained ownership of and full responsibility for certain land adjacent to the Hawesville facility containing potliner disposal areas.

      Southwire has secured its environmental indemnity obligations to the Company through April 1, 2008 by posting a letter of credit in favor of the Company in the amount of $14.0 million. Southwire is obligated to post an additional $15.0 million if its net worth drops below a pre-determined level prior to April 1, 2008. The amount of security Southwire provides may increase (but not above $14.5 million or $29.5 million, as applicable) or decrease (but not below $3.0 million) if certain specified conditions are met.

      The Company cannot be certain Southwire will be able to meet its indemnity obligations. In that event, under certain environmental laws which impose liability regardless of fault, the Company may be liable for any outstanding remedial measures required under the record of decision and for certain liabilities related to the properties previously owned by Metalsco. If Southwire fails to meet its indemnity obligations or if the Company’s shared or assumed liability is significantly greater than anticipated, the Company’s financial condition, results of operations and liquidity could be materially adversely affected.

      Century Aluminum of West Virginia, Inc. continues to perform remedial measures at its Ravenswood facility pursuant to an order issued by the EPA in 1994. Century of West Virginia also conducted a facility investigation under the order evaluating other areas at the Ravenswood facility that may have contamination requiring remediation. The facility investigation has been approved by appropriate agencies. Century of West Virginia has completed interim remediation measures at two sites identified in the facility investigation, and the Company believes no further remediation will be required. A corrective measures study, which will formally document the conclusion of these activities, is being completed with the EPA. The Company believes a significant portion of the contamination on the two sites identified in the facility investigation is attributable to the operations of Kaiser, which had previously owned and operated the Ravenswood facility, and is the financial responsibility of Kaiser.

      On September 28, 2004, the Bankruptcy Court for the District of Delaware approved an agreement by Kaiser to transfer its environmental liability at Ravenswood to TRC Companies, Inc. and TRC Environmental Corporation. The Bankruptcy Court also approved an agreement between, Kaiser, TRC, Century of West Virginia and Pechiney Rolled Products, Inc., effective as of September 1, 2004, pursuant to which TRC assumed all of Kaiser’s environmental liabilities at Ravenswood. TRC has purchased insurance in amounts the Company believes are sufficient to cover the costs of any TRC liability at Ravenswood. Also, as of September 1, 2004, Century of West Virginia and Pechiney entered into an agreement releasing Century of West Virginia from all of the environmental indemnification obligations for Kaiser-related matters arising out of the Century of West Virginia’s 1999 sale of the Ravenswood rolling mill to Pechiney.

      The Company is not aware of any material cost of environmental compliance or any material environmental liability for which it would be responsible at the Mt. Holly facility.

      The Company is a party to an EPA administrative order on consent pursuant to which other past and present owners of an alumina refining facility at St. Croix, Virgin Islands have agreed to carry out a Hydrocarbon Recovery Plan to remove and manage hydrocarbons floating on groundwater underlying the

facility. Pursuant to the Hydrocarbon Recovery Plan, recovered hydrocarbons and groundwater are delivered to the adjacent petroleum refinery where they are received and managed. Lockheed Martin Corporation, which sold the facility to an affiliate of the Company, Virgin Islands Alumina Corporation, or Vialco, in 1989, has tendered indemnity and defense of this matter to Vialco pursuant to terms of the asset purchase agreement between Lockheed and Vialco. The Company’s management does not believe Vialco’s liability under the order or its indemnity to Lockheed will require material payments. Through December 31, 2004, the Company has expended approximately $0.4 million on the Recovery Plan. Although there is no limit on the obligation to make indemnification payments, the Company expects the future potential payments under this indemnification will be approximately $0.2 million which may be offset in part by sales of recoverable hydrocarbons.

      The Company, along with others, including former owners of the Company’s former St. Croix facility, received notice of a threatened lawsuit alleging natural resources damages at the facility. The Company has entered into a joint defense agreement with the other parties who received notification of the threatened lawsuit. While it is not presently possible to determine the outcome of this matter, the Company’s known liabilities with respect to this and other matters relating to compliance and cleanup, based on current information, are not expected to be material and should not materially adversely affect the operating results of the Company. However, if more stringent compliance or cleanup standards under environmental laws or regulations are imposed, previously unknown environmental conditions or damages to natural resources are discovered, or if contributions from other responsible parties with respect to sites for which the Company has cleanup responsibilities are not available, the Company may be subject to additional liability, which may be material.

      Prior to purchasing the Gramercy assets from Kaiser, the Company and Noranda performed a pre-purchase due diligence investigation of the environmental conditions present at the Gramercy plant. The results of this investigation were submitted to state regulatory officials. In addition, as part of this submittal, the Company and Noranda agreed to undertake certain specified remedial activities at the Gramercy plant. Based on the submission, and conditioned on completion of the specified remedial activities, state environmental officials have confirmed that the Company and Noranda met the conditions for bona fide prospective purchase protections against liability for pre-existing environmental conditions at the facility. In addition, pursuant to the terms of the purchase agreement with Kaiser, Kaiser agreed to escrow $2.5 million of the purchase price as an indemnity for expenses incurred in the performance of environmental remediation at the Gramercy plant. GAL, the 50/50 joint venture company formed by the Company and Noranda to purchase the Gramercy plant, plans to spend approximately $0.3 million in 2005 for environmental remediation at the Gramercy plant. In connection with the acquisition, GAL posted a $5.5 million bond as security for certain clean-up obligations that would arise under state environmental laws upon the termination of operations at the Gramercy plant. Based on current information, the Company does not believe its purchase of the Gramercy plant presents the Company with any material environmental liabilities.

      In conjunction with the purchase of the Gramercy plant, the Company and Noranda jointly purchased Kaiser’s 49% interest in Kaiser-Jamaica Bauxite Company, or KJBC, a partnership located in Jamaica and 51% owned by the Jamaican government. Now reconstituted as St. Ann Jamaican Bauxite Partnership, the entity carries out bauxite mining, drying, storage and shipping operations. The Company and Noranda performed a pre-purchase due diligence investigation of the KJBC operations which disclosed no significant environmental liabilities or regulatory non-compliance. While it is impossible to predict what future environmental requirements might be, based on current information, the Company does not believe that the acquisition of KJBC presents the Company with any material environmental liabilities.

Intellectual Property

      The Company owns or has rights to use a number of patents or patent applications relating to various aspects of its operations. The Company does not consider its business to be materially dependent on any of these patents or patent applications.

Employees and Labor Relations

      The Company employs a work force of approximately 1,420 persons in the United States, consisting of 1,150 hourly employees and 270 salaried employees. The Company has approximately 560 hourly employees and 104 salaried employees at the Ravenswood facility, and approximately 590 hourly employees and 150 salaried employees at the Hawesville facility. The bargaining unit employees at the Ravenswood and Hawesville facilities are represented by the United Steelworkers of America (“USWA”). The employees at the Mt. Holly facility are employed by Alcoa and are not unionized. The Company’s corporate office, located in Monterey, California, has 16 salaried employees.

      The represented hourly employees at the Ravenswood facility are covered by a labor agreement with the USWA that expires May 31, 2006. The agreement calls for fixed increases in hourly wages and provides for certain benefit adjustments each year.

      In connection with the Hawesville acquisition, Century negotiated a five-year collective bargaining agreement, expiring March 31, 2006, which covers all of the represented hourly employees at the Hawesville facility. The agreement provides for fixed increases in hourly wages in the first, third, fourth and fifth years and certain benefit adjustments over the life of the agreement.

      At the Gramercy plant, GAL employs 135 salaried employees and 352 unionized hourly employees. In connection with the acquisition, GAL negotiated a new collective bargaining agreement with the United Steelworkers of America that covers all of the represented hourly employees at the Gramercy plant. The wage, benefit and other terms of that agreement, which expires in September 2005, are substantially identical to the terms of the previous agreement with Kaiser. The Company and Noranda established or provide directly certain operating level business functions for the Gramercy plant that were provided by Kaiser prior to the acquisition, including: procurement; shipping; engineering; sales and marketing; human resources; treasury; environmental programs; insurance; information technology and business systems; tax and legal.

      In Iceland, the Company employs 205 people at the Nordural facility, of whom 163 are hourly employees and 42 are salaried. There are six national labor unions represented in Nordural’s unionized work force. The labor contract with these unions, which sets forth the work rules and wages for the covered employees, expired on December 31, 2004. A new contract is expected to be settled early in 2005. Nordural expects to hire up to 160 new employees for the expansion, comprised of approximately 155 hourly employees and 5 salaried employees.

      At the Jamaican mining operations, SABL employs approximately 589 employees, comprised of approximately 139 unionized and non-unionized salaried employees, 333 unionized hourly employees and 117 rotating temporary workers. SABL is currently negotiating with local unions to enter into new labor contracts that are expected to contain substantially similar terms to recently expired labor contracts. The Company and Noranda established or provide directly all non-operating level and certain operating level business functions for the mining operations that were provided by Kaiser prior to the acquisition, including: procurement; shipping; engineering; sales and marketing; human resources; treasury; environmental programs; insurance; information technology and business systems; and legal.

      Century maintains noncontributory defined benefit pension plans for all salaried employees and the hourly employees at the Ravenswood facility and the Company contributes to a multi-employer benefit plan for the hourly employees at the Hawesville facility. In addition, the Company maintains postretirement healthcare and life insurance benefit plans and defined contribution 401(k) plans for its salaried and hourly employees. Management believes that its relations with its employees are good.

      In connection with the Gramercy acquisition, GAL agreed to establish a defined benefit pension plan and a defined contribution plan for employees of the Gramercy plant to replace the plans previously provided by Kaiser. Kaiser retained all worker compensation, pension and post-retirement medical obligations related to pre-acquisition operations at the Gramercy plant.

      In connection with the bauxite mining acquisition, SABL assumed all of Kaiser’s pension and benefit obligations for the employees of the mining operations.

      The Nordural facility is located in Grundartangi, Iceland, approximately 25 miles northwest of Reykjavik, Iceland’s capital. Built in 1998, the Nordural facility is the Company’s most recently constructed and lowest cost facility. It has an annual production capacity of approximately 198 million pounds, which will increase by up to 269 million pounds to approximately 467 million pounds upon completion of an ongoing expansion of the facility, with potential for further expansion to 573 million pounds of annual production capacity. The Nordural facility is situated on two hundred acres leased from the Government of Iceland. See Item 1, “Business — Facilities and Production — Nordural Facility.” The Nordural facility is subject to mortgages in connection with Nordural’s term loan facility as further described in Part II, Item 7, “Management’s Discussion and Analysis — Debt Service.”

      The Hawesville facility occupies 189 acres on a site totaling 747 acres located adjacent to the Ohio River in Hawesville, Kentucky. The Hawesville facility began operations in 1970 and has an annual production capacity of approximately 538 million pounds. As of April 1, 2003, Century owns 100% of the Hawesville facility. From April 1, 2001 to April 1, 2003, Century’s portion of the annual production capacity of the Hawesville facility was 430 million pounds. See Item 1, “Business — Facilities and Production — Hawesville Facility.”

      The Ravenswood facility occupies 350 acres on a site totaling 2,290 acres located adjacent to the Ohio River near Ravenswood, West Virginia. The Ravenswood facility was built in 1957 and has an annual production capacity of approximately 375 million pounds. See Item 1, “Business — Facilities and Production — Ravenswood Facility.”

      The Hawesville and Ravenswood facilities are subject to mortgages in connection with the Company’s outstanding debt as further described in Part II, Item 7, “Management’s Discussion and Analysis — Debt Service.”

      The Mt. Holly facility occupies 1,000 acres on a site totaling 6,500 acres located in Mt. Holly, South Carolina. The Mt. Holly facility was constructed in 1980 and has an annual production capacity of approximately 489 million pounds. Century owns a 49.7% interest in the Mt. Holly facility and the remaining interest is owned by Alcoa. Alcoa manages and operates the facility pursuant to an owners’ agreement whereby each owner furnishes its own alumina for conversion to aluminum and is responsible for its pro rata share of the operating and conversion costs. See Item 1, “Business — Facilities and Production — Mt. Holly Facility.”

      The Gramercy plant sits on a site totaling 1,650 acres located adjacent to the Mississippi River in Gramercy, Louisiana. The Gramercy plant began operations in 1959 and consists of a production facility, a powerhouse for steam and electricity production, a deep water dock and a barge loading facility. Extensive portions of the Gramercy plant were rebuilt and modernized between 2000 and 2002. The Gramercy plant currently produces alumina at a capacity rate of approximately 1.2 million metric tons per year, consisting of approximately 80% smelter grade alumina and 20% alumina hydrate, or chemical grade alumina. See Item 1, “Business — Facilities and Production — The Gramercy Facility” for a description of the alumina refining operations at the Gramercy plant.

      The bauxite mining operations of the Company are located in St. Ann, Jamaica. Under the terms of mining rights granted by the GOJ, SABL mines the land covered by the mining rights and the GOJ retains surface rights and ownership of the land. The GOJ granted the mining rights and entered into other agreements with SABL for the purpose of ensuring the Gramercy plant will have sufficient reserves to meet its

annual alumina requirements and existing or contemplated future obligations under third party contracts. Under the mining rights, SABL is entitled to mine 4.5 million dry metric tons, or DMT, of bauxite on specified lands annually through September 30, 2030. The GOJ is required to provide additional land if the land covered by the mining rights does not contain sufficient levels of commercially exploitable bauxite. See Item 1, “Business — Facilities and Production — The Gramercy Facility” for a description of the alumina refining operations at the Gramercy plant and bauxite mining operations in Jamaica.

      Equipment failures at the Ravenswood, Mt. Holly, Hawesville, Nordural, or Gramercy facilities could limit or shut down the Company’s production for a significant period of time. In order to minimize the risk of equipment failure, the Company follows a comprehensive maintenance and loss prevention program and periodically reviews its failure exposure.

      The Company may suffer losses due to a temporary or prolonged interruption of the supply of electrical power to its facilities, which can be caused by unusually high demand, blackouts, equipment failure, natural disasters or other catastrophic events. See Part II, Item 7, “Risk Factors.”

      The Company has pending against it or may be subject to various lawsuits, claims and proceedings related primarily to employment, commercial, environmental and safety and health matters. Although it is not presently possible to determine the outcome of these matters, management believes the ultimate disposition will not have a material adverse effect on the Company’s financial condition, results of operations, or liquidity. For a description of certain environmental matters involving the Company, see Item 1, “Environmental Matters.”

      No matters were submitted to a vote of security holders of the Company during the fourth quarter of 2004.

Executive Officers

      The following table sets forth certain information concerning the executive officers of the Company. Each such person serves at the discretion of the Board of Directors.

      Craig A. Davis, who served as the Company’s Chief Executive Officer for more than five years through January 1, 2003, was reelected as its Chief Executive Officer on October 15, 2003.

PART II

      The Company’s common stock trades on the NASDAQ National Market tier of the NASDAQ Stock Market under the symbol: CENX. The following table sets forth, on a quarterly basis, the high and low sales prices of the common stock during the two most recent fiscal years.

      At February 28, 2005, there were 23 holders of record of the Company’s outstanding common stock, which does not include the number of beneficial owners whose common stock was held in street name.

      The Company did not declare any dividends in 2004 or 2003 on its common stock. The Company did not declare or pay any dividends in 2003 on its preferred stock; however, in May 2004, the Company paid $3.3 million in dividend arrearages on its convertible preferred stock. In May 2004, all of the outstanding shares of the Company’s convertible preferred stock were converted into common stock, eliminating the accumulation of dividends on the Company’s preferred stock. The Company’s revolving credit facility and the indenture governing the Company’s senior notes, among other things, contain restrictions on the payment of dividends by the Company. See Part II, Item 7, “Liquidity and Capital Resources.” Nordural’s new term loan facility, among other things, contains restrictions on Nordural’s ability to pay dividends. See Part II, Item 7, “Management’s Discussion and Analysis — Recent Developments — Nordural’s New Term Loan Facility.” The Company has the capacity to pay dividends subject to certain financial covenants under the revolving line of credit and the indenture governing its senior notes. Although the Company does not anticipate declaring dividends in the near future, under its most restrictive covenants contained in the revolving line of credit, the Company would be permitted to pay dividends up to $5.0 million.

      The following table presents consolidated financial data of the Company for the years indicated. The selected consolidated historical balance sheet data as of each of the years ended December 31, 2004 and 2003 and the selected consolidated statement of operations data for each of the years ended December 31, 2004, 2003, and 2002 is derived from the Company’s consolidated financial statements audited by Deloitte & Touche LLP which are included herein. The selected consolidated historical balance sheet data as of each of the years ended December 31, 2002, 2001 and 2000 and the selected consolidated statement of operations data for each of the years ended December 31, 2001 and 2000 is derived from the Company’s consolidated financial statements audited by Deloitte & Touche LLP which are not included herein. The Company’s selected historical results of operations include:

      Accordingly, the results for those periods and prior periods are not fully comparable to the results of operations for fiscal year 2004 and are not indicative of the Company’s current business. The information set forth below should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Financial Statements and Supplementary Data” and notes thereto appearing in Part II, Items 7 and 8, respectively.

RISK FACTORS

      The following describes certain of the risks and uncertainties faced by the Company that could cause its future results to differ materially from its current results and from those anticipated in its forward-looking statements. These risk factors should be considered together with the other risks and uncertainties described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere herein.

      The Company’s operating results depend on the market for primary aluminum, which is a cyclical commodity affected by global demand and supply conditions. Historically, global demand and prices for primary aluminum have fluctuated in part due to economic and market conditions in the United States and other major global economies, as well as currency fluctuations. The relative pricing of other materials, such as steel, plastic and glass, which are used as alternatives for aluminum in some applications, also affects demand for aluminum. Certain aluminum end-use markets, including the automotive sector and the building and construction sector, are also cyclical. When downturns occur in these sectors, demand for primary aluminum decreases resulting in lower prices for the Company’s products. Over the past twenty years, the average annual cash price for primary aluminum on the LME was $0.69 per pound and has ranged from a low of $0.47 per pound in 1985 to a high of $1.15 per pound in 1988. The average LME price was $0.65 per pound for the year ended December 31, 2003 and $0.78 per pound for the year ended December 31, 2004. Primary aluminum prices could decline below current levels, reducing the Company’s earnings and cash flows. A prolonged downturn in prices for primary aluminum could significantly reduce the amount of cash available to the Company to meet its current obligations and fund its long-term business strategies.

      Conversely, if prices increase, certain of the Company’s hedging transactions, including its LME-based alumina contracts, may limit the Company’s ability to take advantage of the increased prices. See “Item 7A — Quantitative and Qualitative Disclosures About Market Risk.”

      A combined total of 53% of the Company’s consolidated net sales for 2004 were derived from sales to Pechiney Rolled Products, LLC and Southwire Company. Pechiney was acquired by Alcan in February 2004. Pechiney’s facility is located adjacent to the Ravenswood facility and Southwire’s facility is located adjacent to the Hawesville facility. Due to this proximity, the Company is able to deliver molten aluminum to these customers, thereby eliminating the Company’s casting and shipping costs and its customers’ remelting costs. The Company has long-term contracts with Pechiney and Southwire which are due to expire at the end of 2005 and at the end of 2011, respectively. The Company has entered into a new contract for the supply of power to the Ravenswood facility that would extend the Pechiney contract through July 31, 2007. The new power contract is subject to certain approvals by the Public Service Commission of West Virginia. See Item 1, “Facilities and Production — Ravenswood facility.” Pechiney has the right to reduce its purchases under its contract by 50%, upon 12 months’ notice, and Southwire has the right to reduce purchases under its contract by 20% beginning in 2009. The Company may be unable to extend or replace these contracts when they terminate. If the Company is unable to renew these contracts when they expire, or if either customer

significantly reduces its purchases under those contracts, the Company will incur higher casting and shipping costs.

      The Company benefits from its relationship with Glencore International AG, its largest shareholder. The Company has entered into various long-term contracts with Glencore to sell up to 13.4% of its current annual primary aluminum production and to purchase up to 53.5% of its annual alumina requirements under contracts expiring at various dates from 2006 through 2013. In addition, the Company has entered into an alumina tolling agreement with Glencore for 198 million pounds of the expansion capacity at the Nordural facility. The Company also enters into forward sales and hedging contracts with Glencore, which helps the Company manage its exposure to fluctuating aluminum prices. Because Glencore is a major customer, supplier and metal hedge counterparty, a material change in the Company’s relationship with Glencore, including any significant change in its investment in the Company, could affect how the Company purchases raw materials, sells its products and hedges its exposure to metal price risk, which could impact the Company’s operating costs.

      The Company may incur losses due to a temporary or prolonged interruption of the supply of electrical power to its facilities, which can be caused by unusually high demand, blackouts, equipment failure, natural disasters or other catastrophic events. Large amounts of electricity are used to produce primary aluminum, and any loss of power which causes an equipment shutdown can result in the hardening or “freezing” of molten aluminum in the pots where it is produced. If this occurs, the Company may lose production for a prolonged period of time and incur significant losses. Although the Company maintains property and business interruption insurance to mitigate losses resulting from catastrophic events, it may be required to pay significant amounts under the deductible provisions of those insurance policies. In addition, the coverage under those policies may not be sufficient to cover all losses, or may not cover certain events. Certain of the Company’s insurance policies do not cover any losses that may be incurred if the Company’s suppliers are unable to provide power during periods of unusually high demand. Certain losses which are not covered by insurance may trigger a default under the Company’s revolving credit facility.

      The Company depends on a limited number of suppliers for alumina, the principal raw material used to produce primary aluminum. Supply of alumina has been constrained over the past two years, and the construction of new production facilities requires substantial lead time. Disruptions to the Company’s supply of alumina could occur for a variety of reasons, including disruptions of production at a particular supplier’s alumina refinery. These disruptions may require the Company to purchase alumina on less favorable terms than under its current agreements. Spot alumina prices are currently substantially higher than the prices the Company pays under its long-term agreements.

      The Company and Noranda Finance Inc., through 50/50 joint venture companies, recently purchased the Gramercy, Louisiana alumina refinery that supplies the alumina used at the Company’s Hawesville and Noranda’s New Madrid primary aluminum production facilities. As part of the acquisition, the joint venture also purchased an interest in a Jamaican partnership that owns bauxite mining assets in St. Ann, Jamaica. Bauxite is the principal raw material used in the production of alumina and all of the bauxite used at the Gramercy alumina refinery is purchased from the Jamaican partnership. In October 2004, certain equipment used by the partnership to load bauxite at the St. Ann port facility failed, resulting in a temporary interruption of bauxite shipments. The St. Ann port facility, which is used to ship bauxite to the Gramercy alumina facility and to other customers, operated at a reduced shipping level until full operations resumed in December 2004.

If there is a significant disruption of bauxite shipments in the future, the joint venture could incur additional costs if it is required to use bauxite from other sources.

      The Gramercy refinery that the Company and Noranda recently acquired from Kaiser supplies all of the alumina used at the Company’s Hawesville facility. Prior to the acquisition, the Company purchased alumina from Kaiser under a long-term contract at prices based on the LME price for primary aluminum. Following the acquisition, that contract was replaced with a contract that provides for alumina prices based on the Gramercy refinery’s production costs. As a result, the price the Company pays for the alumina used at its Hawesville facility is now based on the cost of alumina production, rather than the LME price for primary aluminum. Those production costs could be materially higher than the price paid under the Company previous LME-based contract during periods when aluminum prices are low and natural gas prices are high.

      The Company’s operating results are sensitive to changes in the price of primary aluminum and the raw materials used in its production. Although the Company attempts to mitigate the effects of such price fluctuations through the use of various fixed-price commitments and financial instruments, these efforts may limit its ability to take advantage of favorable changes in the market prices for primary aluminum or raw materials. See “Item 7A — Quantitative and Qualitative Disclosures About Market Risk.”

      Electricity represents the Company’s single largest operating cost. As a result, the availability of electricity at affordable prices is crucial to the profitability of the Company’s operations. While the Company purchases primarily all of its electricity for its existing U.S. facilities under fixed-price contracts through 2005, a portion of the contracted cost of the electricity supplied to the Mt. Holly facility varies with supplier’s fuel costs. An increase in these fuel costs would increase the price the Mt. Holly facility pays for electricity. The fixed price portions of the Company’s current power contracts are due to expire at various times from the end of 2005 through 2010. The Company has entered into a new power contract with Appalachian Power Company for the supply of power to the Ravenswood facility beginning January 1, 2006. That agreement, which must be affirmed by the Public Services Commission of West Virginia, would have an initial term of 2 years and continue thereafter until the Company gives 12 months’ notice of cancellation. If the Company is unable to obtain power at affordable rates upon the expiration of its contracts, the Company may be forced to curtail or idle a portion of its production capacity, which would lower its revenues and adversely affect the profitability of its operations.

      The bargaining unit employees at the Company’s Ravenswood and Hawesville facilities and at the Gramercy refinery are represented by the United Steel Workers of America. The Company’s labor contracts expire in 2006 at the Ravenswood and Hawesville facilities and in 2005 at the Gramercy plant. Nordural’s employees are represented by unions and were employed under a contract that expired at the end of 2004. New labor contracts are being negotiated to replace the recently expired contracts covering employees at Nordural and the Jamaican bauxite mining operations. The Company may be unable to satisfactorily renegotiate those labor contracts. In addition, existing labor contracts may not prevent a strike or work stoppage at any of these facilities in the future, and any such work stoppage could prevent or significantly impair the Company’s ability to conduct production operations at those facilities.

      The Company’s management structure is streamlined and, as a result, it relies heavily on a small core senior management team. The unexpected loss of the services of one or more key employees could significantly harm the Company’s business, financial condition and operating results. The employment agreements for certain key management personnel expire at the end of 2005 and it is anticipated that one or more of those individuals may retire at that time.

      The Company is obligated to comply with various federal, state and other environmental laws and regulations, including the environmental laws and regulations of Iceland, the European Economic Area and Jamaica. Environmental laws and regulations may expose the Company to costs or liabilities relating to its manufacturing operations or property ownership. The Company incurs operating costs and capital expenditures on an ongoing basis to comply with applicable environmental laws and regulations. In addition, the Company is currently and may in the future be responsible for the cleanup of contamination at some of its current and former manufacturing facilities or for the amelioration of damage to natural resources. For example, the Company, along with others, including former owners of the Company’s former St. Croix facility, received notice of a threatened lawsuit alleging natural resources damages at the facility. While it is not presently possible to determine the outcome of this matter, the Company’s known liabilities with respect to this and other matters relating to compliance and cleanup, based on current information, are not expected to be material and should not materially adversely affect the Company’s operating results. However, if more stringent compliance or cleanup standards under environmental laws or regulations are imposed, previously unknown environmental conditions or damages to natural resources are discovered, or if contributions from other responsible parties with respect to sites for which the Company has cleanup responsibilities are not available, the Company may be subject to additional liability, which may be material. Further, additional environmental matters for which the Company may be liable may arise in the future at its present sites where no problem is currently known, with respect to sites previously owned or operated by the Company, by related corporate entities or by its predecessors, or at sites that the Company may acquire in the future. Overall production costs may become prohibitively expensive and prevent the Company from effectively competing in price sensitive markets if future capital expenditures and costs for environmental compliance or cleanup are significantly greater than current or projected expenditures and costs. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Environmental Expenditures and Other Contingencies” and Note 12 to the Company’s audited consolidated financial statements for a detailed description of the Company’s environmental matters and associated costs and risks.

      In April 2004, the Company acquired the Nordural facility, which is located in Grundartangi, Iceland. In October 2004, the Company acquired a joint venture interest in an alumina refinery located in Gramercy, Louisiana and a 49% interest in related bauxite operations in Jamaica. The Company may make other strategic acquisitions in the future. The Company is subject to numerous risks as a result of its acquisitions, including the following:

      Accordingly, the Company’s recent or future acquisitions might not improve the Company’s competitive position and business prospects as anticipated.

      The ongoing expansion of the Company’s Nordural facility, which is expected to be completed in late 2006, will more than double the facility’s existing production capacity. The expected benefits of the expansion may not be realized if Nordural is unable to complete the expansion in the time forecast or experiences significant cost overruns. The Company may add additional capacity to the current expansion project or in a future expansion of the Nordural facility. In each case, the Company’s ability to add the additional capacity depends on its ability to enter into certain key contracts for that capacity.

      The Nordural facility is the Company’s first facility located outside of the United States. The bauxite operations related to the Gramercy plant, which the Company recently acquired through a joint venture with Noranda, are located in Jamaica. The Company may in the future consider other acquisitions in foreign countries. International operations may expose the Company to risks, including unexpected changes in foreign laws and regulations, political and economic instability, challenges in managing foreign operations, increased cost to adapt the Company’s systems and practices to those used in foreign countries, export duties, tariffs and other trade barriers, and the burdens of complying with a wide variety of foreign laws. In addition, the Company will be exposed to fluctuations in currency exchange rates and, as a result, an increase in the value of foreign currencies relative to the U.S. dollar could increase its operating expenses which are denominated and payable in those currencies. For example, Nordural’s revenues are denominated in U.S. dollars, while its labor costs are denominated in Icelandic kronur and a portion of its anode costs are denominated in euros.

      The Company historical financial information is not necessarily indicative of its future results of operations, financial position and cash flows. For example, the Company’s historical financial data does not reflect the effects of:

      The Company is highly leveraged. It had an aggregate of approximately $524.1 million of outstanding indebtedness for borrowed money as of December 31, 2004. In addition, Nordural can borrow up to an aggregate of $365.0 million under its new term loan facility. The level of the Company’s indebtedness could have important consequences, including:

      In addition to its indebtedness, the Company’s has liabilities and other obligations which could reduce cash available for other purposes and limit its ability to pursue its growth strategy. See “Liquidity and Capital Resources.” The Company will need a significant amount of cash to service its debt. While the Company’s debt service has decreased as a result of the 2004 refinancing, it will increase as Nordural draws down under its new term loan facility. In addition, the Company will be required to settle in cash up to the principal amount of its convertible notes (which are convertible at any time) upon conversion, which could increase its debt service obligations.

      The Company is also exposed to risks of interest rate increases. Nordural recently entered into a new $365.0 million senior term loan facility. Nordural’s annual debt service requirements will vary, as amounts outstanding under its new term loan facility will bear interest at a variable rate.

      The Company’s ability to pay interest and to repay or refinance its indebtedness, including its senior term notes and convertible notes, and satisfy other commitments, including funding the Nordural expansion, will depend upon its future operating performance, which is subject to general economic, financial, competitive, legislative, regulatory, business and other factors that are beyond its control. Accordingly, there is no assurance that the Company’s business will generate sufficient cash flow from operations or that future borrowings will be available to the Company in an amount sufficient to enable it to pay its indebtedness, including the notes, or to fund its other liquidity needs. If the Company is unable to meet its debt service obligations or fund its other liquidity needs, the Company could attempt to restructure or refinance its indebtedness or seek additional equity capital. There can be no assurance that the Company will be able to accomplish those actions on satisfactory terms, or at all.

      The Company’s revolving credit facility and the indenture governing its senior term notes each contain various covenants that restrict the way it conducts its business and limits the Company’s ability to incur debt, pay dividends and engage in transactions such as acquisitions and investments, which may impair its ability to pursue its growth strategy. See “Liquidity and Capital Resources — Debt Service.” Any failure to comply with those covenants may constitute a breach under the revolving credit facility or the indenture governing the notes, which may result in the acceleration of all or a substantial portion of its outstanding indebtedness and termination of commitments under its revolving credit facility. If its indebtedness is accelerated, the Company may be unable to repay those amounts upon acceleration and the Company’s secured lenders could foreclose on any collateral securing the Company’s secured debt.

      Substantially all of Nordural’s assets are pledged as security under its new term loan facility, including, but not limited to, all of Nordural’s property, plant and equipment related to the smelter and the harbor area and all of Nordural’s current and future inventory, receivables, insurance policies, bank accounts, and rights under specified contracts relating to the operation of the Nordural facility, including its tolling, anode supply and power contracts having a term longer than two years. In addition, the shares of Nordural have been pledged to the lenders as collateral. If Nordural is unable to comply with these covenants, the lenders would be able to cancel commitments under Nordural’s loan facility, cause all or part of the amounts outstanding under the loan facility to be immediately due and payable and foreclose on any collateral securing the loan facility. The new term loan facility also contains restrictions on Nordural’s ability to pay dividends, including a requirement that Nordural make a repayment of principal in an amount equal to 50% of any dividend paid to shareholders. See “Liquidity and Capital Resources.” Based on Nordural’s needs for cash to finance its expansion and operations, the Company does not currently anticipate that Nordural will distribute any cash until the expansion is complete.

      The Company is a holding company and conducts all of its operations through its subsidiaries. The Company’s ability to meet its debt service obligations depends upon its receipt of dividends from its subsidiaries. Nordural’s new senior term loan facility places significant limits on Nordural’s ability to pay dividends. Subject to the restrictions contained in the Company’s revolving credit facility and the indenture governing its senior notes, future borrowings by the Company’s subsidiaries could contain restrictions or prohibitions on the payment of dividends by those subsidiaries. In addition, under applicable law, the Company’s subsidiaries could be limited in the amounts that they are permitted to pay as dividends on their capital stock.

      Despite its current and anticipated debt levels, the Company may be able to incur significant additional indebtedness from time to time, subject to the restrictions contained in its revolving credit facility and the indenture governing its senior term notes. The Company may borrow amounts under its revolving credit facility, and any such borrowings would be secured by all of the Company’s accounts receivable and inventory. Although the indenture governing the notes contains restrictions on the Company’s incurrence of debt, these restrictions are subject to a number of qualifications and exceptions and, under certain circumstances, the Company could incur substantial indebtedness while remaining in compliance with these restrictions. See “Management’s Discussion and Analysis of Results of Operations and Financial Condition — Liquidity and Capital Resources.”

      The market price of the Company’s common stock has experienced significant volatility from time to time, and this volatility may continue in the future. From January 1, 2004, through March 11, 2005, the intra-day sales price of our common stock on NASDAQ ranged from $18.64 to $34.27 per share. In addition, the securities markets have experienced significant price and volume fluctuations. The market price for the Company’s common stock may be affected by a number of factors, including actual or anticipated variations in the Company’s quarterly results of operations, expectations about the future price of aluminum, changes in earnings estimates or recommendations by securities analysts, changes in research coverage by securities analysts, the conversion of some or all of the Company’s outstanding convertible notes, any announcement by the Company of significant acquisitions, strategic partnerships, joint ventures or capital commitments, developments in the aluminum industry and sales of substantial numbers of shares by current holders of the Company’s common stock in the public market. In addition, general economic, political and market conditions and other factors unrelated to the Company’s operating performance may cause the market price of its common stock to be volatile.

      Certain provisions of the Company’s restated certificate of incorporation and amended and restated bylaws, as well as provisions of the Delaware General Corporation Law may have the effect of delaying, deferring or preventing a change of control of the Company, including transactions in which the Company’s stockholders might otherwise have received a substantial premium for their shares over then current market prices. For example, these provisions:

      In addition, certain officers of the Company have entered into employment and severance compensation agreements that provide for cash payments, immediate vesting of stock options and performance shares and acceleration of other benefits under certain circumstances, including a change in control of the Company. The Company’s 1996 Stock Incentive Plan also provides for acceleration of the ability to exercise stock options and the vesting of performance shares upon a change of control, and the Company’s Non-Employee Directors Stock Option Plan provides for acceleration of an option holder’s ability to exercise stock options upon a change of control.

      The following discussion reflects the Company’s historical results of operations, which do not include results from: (1) the Company’s 80% interest in the Hawesville facility until acquired in April 2001, (2) the remaining 20% interest in the Hawesville facility until acquired in April 2003, (3) the Company’s ownership of Nordural until acquired in late April 2004 and (4) the Company’s ownership interest in the Gramercy assets until acquired in October 2004. Accordingly, the results for fiscal years 2002 and 2003 are not fully comparable to the results of operations for fiscal year 2004. Historical results are not indicative of the Company’s current business. You should read the following discussion in conjunction with the Company’s consolidated financial statements included elsewhere in this filing.

Overview

      The Company produces primary aluminum. The aluminum industry is cyclical and the price of primary aluminum (which trades as a commodity) is determined by global supply and demand. The key determinants of the Company’s results of operations and cash flow from operations are as follows:

      Average realized price and cost of goods sold per pound shipped are key performance indicators. Revenue varies significantly from period to period due to fluctuations in the LME price of aluminum. Any adverse changes in the conditions that affect the market price of primary aluminum could have a material adverse effect on the Company’s results of operations and cash flows. Revenue is also impacted by the Company’s hedging activities. Working capital is relatively stable. Fluctuations in working capital are influenced by the LME price of primary aluminum and by the timing of cash receipts and disbursements from major customers and suppliers.

      Cost of goods sold, excluding alumina, is expected to remain relatively stable because the Company’s plants operate near capacity and its major cost drivers are covered by long-term contracts. Fluctuations in the cost of alumina are expected as the pricing in these contracts, except for the Gramercy alumina contract, is variable and based on LME prices. Power contracts for U.S. facilities provide for primarily fixed priced power through 2005, subject to adjustments for fuel costs for Mt. Holly. On February 18, 2005, Century of West Virginia signed an agreement with Appalachian Power Company for the supply of electricity to the Ravenswood facility beginning January 1, 2006. See Item 1, “Business — Facilities and Production — Ravenswood Facility.” Power usage is expected to be consistent with prior periods. Labor costs should be consistent with modest increases for negotiated salary and benefit increases.

      Through the Company’s ownership of the Ravenswood, Hawesville and Nordural facilities, and the Company’s ownership interest in the Mt. Holly facility, the Company has an annual production capacity of approximately 1.4 billion pounds of primary aluminum.

Recent Developments

      On February 10, 2005, Nordural executed a loan agreement and other agreements and documents related to a new $365.0 million senior term loan facility arranged by Landsbanki Islands hf. and Kaupthing Bank hf. The term loan facility closed and funded on February 15, 2005. Amounts borrowed under the new term loan facility refinanced debt under Nordural’s prior term loan facility, and will be used to finance a portion of the costs associated with the ongoing expansion of the Nordural facility and for Nordural’s general corporate

purposes. Borrowings are subject to customary conditions, including the absence of any default under the loan agreement or any material adverse change in Nordural’s condition (financial or otherwise), business, operations, assets, liabilities or prospects. See “Liquidity and Capital Resources — Debt Service — Nordural’s New Term Loan Facility”

      On October 1, 2004, the Company and Noranda Finance Inc., through 50/50 joint venture companies, acquired an alumina refinery in Gramercy, Louisiana and related bauxite mining assets in Jamaica (collectively, the “Gramercy assets”) from Kaiser Aluminum & Chemical Company (the “Gramercy acquisition.”). The purchase price for the Gramercy assets was approximately $23 million, subject to working capital adjustments. The Company and Noranda each paid one-half, or $11.5 million of the unadjusted purchase price. Kaiser sold the Gramercy assets as part of its reorganization to emerge from Chapter 11 bankruptcy. Gramercy has an annual production capacity of 1.2 million metric tons of alumina, approximately 80% of which is supplied to the Hawesville facility and to a primary aluminum production facility separately owned by Noranda. The Hawesville facility purchases virtually all of its alumina requirements from Gramercy.

      In October 2004, certain bauxite loading equipment used by the bauxite mining partnership at its St. Ann, Jamaica port facility failed, resulting in a temporary interruption of bauxite shipments from the facility. The St. Ann port facility, which is used to ship bauxite to the Gramercy alumina facility and to other customers, operated at a reduced shipping level until full operations resumed in December 2004.

     Post-Acquisition Operation of the Gramercy assets

      Alumina is the principal raw material used in the production of primary aluminum. The Company acquired its share of the Gramercy assets to ensure a stable supply of alumina to the Company’s primary aluminum production facilities at acceptable costs and to avoid the risk of significant cost increases if the Company was required to replace this source of supply in the current high priced and volatile spot alumina market.

      Prior to the acquisition, the Gramercy assets were operated by Kaiser as a non-autonomous part of Kaiser’s business. The dominant portion of the revenues from these operations was derived from alumina sales to Century and to Noranda. Following the acquisition, the Company uses its share of the Gramercy assets as a source of alumina for its Hawesville facility. Third party CGA and bauxite sales are incidental and, standing alone, are not significant and will be maintained only to optimize fixed costs. Further, Century and Noranda have assumed certain essential management and business functions previously provided by Kaiser. Accordingly, there is a lack of continuity between pre- and post-acquisition revenue-producing activity and the manner in which essential management and business functions are handled. In addition, Kaiser did not maintain separate financial statements for the operations that comprise the Gramercy assets. Based on the foregoing, the Company believes that disclosure of historical financial information relating to the Gramercy assets would not be material to an understanding of the Company’s future operations.

      On August 26, 2004, the Company announced the Company’s repurchase of approximately $315.1 million in aggregate principal amount of the Company’s 11.75% senior secured first mortgage notes due 2008 that were validly tendered pursuant to a tender offer and consent solicitation commenced on July 29, 2004. Under the terms of the tender offer, the Company paid $1,096.86 for each $1,000 principal amount of first mortgage notes purchased in the tender offer, plus accrued and unpaid interest. Holders who tendered their notes prior to 5:00 p.m., New York City time, on August 6, 2004, received an additional payment of $20.00 per $1,000 of principal amount of first mortgage notes tendered.

      The primary purpose of the tender offer and consent solicitation was to refinance $325.0 million of the Company’s outstanding first mortgage notes with debt bearing a lower interest rate, thereby reducing the Company’s annual interest expense. Approximately $9.9 million in aggregate principal amount of first mortgage notes remain outstanding following the tender offer and are scheduled to mature on April 15, 2008.

In connection with the tender offer and consent solicitation, the Company received consents needed to amend the indenture governing the remaining first mortgage notes to eliminate substantially all restrictive covenants and certain default provisions. The Company has provided the trustee under the indenture notice of its intent to call for redemption all outstanding first mortgage notes on or about April 15, 2005.

      The Company financed the tender offer and consent solicitation with a portion of the net proceeds from (i) the private placement of $175.0 million aggregate principal amount of the Company’s 1.75% convertible senior notes due August 1, 2024, and (ii) the private placement of $250.0 million aggregate principal amount of the Company’s 7.5% senior notes due August 15, 2014. The Company used the remaining proceeds from the sale of the Company’s convertible notes and senior notes for general corporate purposes.

      On April 27, 2004, the Company completed the acquisition of all of the outstanding equity shares of Nordural hf. (now known as Nordural ehf.) from Columbia Ventures Corporation. Nordural is an Icelandic company that owns and operates the Nordural facility, a primary aluminum reduction facility located in Grundartangi, Iceland. Built in 1998, the Nordural facility is the Company’s most recently constructed and lowest cost facility. It currently has an annual production capacity of approximately 198 million pounds.

      Since the acquisition, the Company has commenced work on an expansion of the Nordural facility to increase its annual production capacity to approximately 467 million pounds, or more than double its current annual production capacity. As currently planned, the expansion will add up to 269 million pounds to the Nordural facility’s annual production capacity. The expansion is projected to be completed by late 2006 and is expected to cost approximately $454 million.

      In connection with the expansion, the Company agreed on the terms of amendments to several long-term contracts with the Government of Iceland, local municipalities and the Grundartangi Harbour Fund, which were effective upon the closing of Nordural’s new term loan facility. The Company agreed to an LME-based ten-year alumina tolling contract with Glencore for 198 million pounds of the expansion capacity. The power needed for the expansion capacity will be purchased under a long-term LME-based agreement with Sudurnes Energy and Reykjavik Energy. The Company’s new energy agreement includes power for approximately 18 million pounds of additional capacity, upon satisfaction of certain conditions, including the completion of a power transmission agreement. With the additional 18 million pounds of capacity, the total annual production capacity of the Nordural facility would increase to 485 million pounds by late 2006. A decision on the additional 18 million pounds of capacity is expected in early 2005. Following completion of the expansion, Nordural will have all the infrastructure and support facilities necessary for further expansion to 573 million pounds of annual production capacity. This expansion would be made at relatively low capital cost. The Company is in discussions for the supply of electric power to support this further expansion.

      The Company routinely enters into market priced contracts for the sale of primary aluminum. A summary of Century’s long-term primary aluminum sales contracts is provided below. See Part I, Item 1, “Sales and Distribution” for further discussion of these contracts.

      Apart from the Pechiney Metal Agreement, New Sales Contract, the Glencore Metal Agreement and Southwire Metal Agreement, the Company had forward delivery contracts to sell 249.4 million pounds and 351.8 million pounds of primary aluminum at December 31, 2004 and December 31, 2003, respectively. Of these forward delivery contracts, the Company had fixed price commitments to sell 13.3 million pounds and 70.5 million pounds of primary aluminum at December 31, 2004 and December 31, 2003, respectively, of which none at December 31, 2004 and 53.5 million pounds December 31, 2003, were with Glencore.

      The Company is party to long-term supply agreements with Glencore that supply a fixed quantity of alumina to the Company’s Ravenswood and Mt. Holly facilities at prices indexed to the price of primary

aluminum quoted on the LME. In addition, as part of the Gramercy acquisition, the Company entered into a long-term supply agreement on November 2, 2004 with Gramercy Alumina LLC that supplies a fixed quantity of alumina to the Company’s Hawesville facility at prices based on the alumina production costs at the Gramercy refinery. A summary of these agreements is provided below. The Company’s Nordural facility toll converts alumina provided by BHP Billiton, and will toll convert alumina provided by Glencore beginning in 2006. See Part I, Item 1, “Facilities and Production” for additional discussion of the Company’s alumina and tolling agreements.

      The Company uses significant amounts of electricity in the aluminum production process. A summary of these power supply agreements is provided below.

      The Company’s labor costs at the Ravenswood and Hawesville facilities are subject to the terms of labor contracts which generally have provisions for annual fixed increases in hourly wages and benefits adjustments. The six national labor unions represented at the Nordural facility operate under a labor contract that establishes wages and work rules for covered employees. The employees at the Mt. Holly facility are employed by Alcoa and are not unionized. The two national labor unions represented at the Jamaican bauxite mining operations operate under labor contracts that establish wages and work rules for covered employees on a plant specific basis. A summary of key labor agreements is provided below. See Item 1, “Business — Employees and Labor Relations” for additional discussion about the Company’s work force.

Application of Critical Accounting Policies

      The Company’s significant accounting policies are discussed in Note 1 of the consolidated financial statements. The preparation of the financial statements requires that management make subjective estimates, assumptions and judgments in applying these accounting policies. Those judgments are normally based on knowledge and experience about past and current events and on assumptions about future events. Critical accounting estimates require management to make assumptions about matters that are highly uncertain at the time of the estimate and a change in these estimates may have a material impact on the presentation of the Company’s financial position or results of operations. Significant judgments and estimates made by the Company include expenses and liabilities related to pensions and other postemployment benefits and forward delivery contracts and financial instruments.

      The Company sponsors various pension plans and also participates in a union sponsored multi-employer pension plan for the collective bargaining unit employees at the Hawesville facility. The liabilities and annual income or expense of the Company’s pension and other postemployment benefit plans are determined using methodologies that involve several actuarial assumptions, the most significant of which are the discount rate and the long-term rate of asset return.

      In developing its expected long-term rate of return assumption for pension fund assets, the Company evaluated input from its actuaries, including their review of asset class return expectations as well as long-term inflation assumptions. Projected returns are based on historical returns of broad equity and bond indices. The Company also considered its historical 10-year compound returns. Century anticipates that the Company’s investments will generate long-term rates of return of 9.0%. The Company’s expected long-term rate of return is based on an assumed asset allocation of 65% equity funds and 35% fixed-income funds.

      The discount rate that the Company utilizes for determining future pension and post employment obligations is based on a review of long-term bonds that receive one of the two highest ratings given by a

recognized rating agency. The discount rate determined on this basis has decreased to 5.75% at December 31, 2004 from 6.25% and 6.5% at December 31, 2003 and 2002, respectively.

      Lowering the expected long-term rate of return by 0.5% (from 9.0% to 8.5%) would have increased the Company’s pension expense for the year ended December 31, 2004 by approximately $0.3 million. Lowering the discount rate assumptions by 0.5% would have increased the Company’s pension expense for the year ended December 31, 2004 by approximately $0.4 million.

      The Company provides postemployment benefit plans that provide health care and life insurance benefits for substantially all retired employees. SFAS No. 106 requires the Company to accrue the estimated cost of providing postretirement benefits during the working careers of those employees who could become eligible for such benefits when they retire. The Company funds these benefits as the retirees submit claims.

      Measurement of the Company’s postretirement benefit obligations requires the use of several assumptions about factors that will affect the amount and timing of future benefit payments. The assumed health care cost trend rates are the most critical assumptions for measurement of the postretirement benefits obligation. Changes in the health care cost trend rates have a significant effect on the amounts reported for the health care benefit obligations.

      The Company assumes medical inflation is initially 9%, declining to 5% over six years and thereafter. A one-percentage-point change in the assumed health care cost trend rates would have the following effects in 2004:

      The Company routinely enters into market priced physical and fixed-priced financial contracts for the sale of primary aluminum and the purchase of raw materials in future periods. The Company applies the provisions of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities, as amended,” in accounting for these types of contracts. For those physical delivery contracts which management believes are probable of future delivery, such contracts are classified as normal purchases and normal sales and are not accounted for as derivatives.

      The aluminum-based financial and physical delivery contracts that are derivatives, as provided for in current accounting standards, are marked-to-market using the LME spot and forward market for primary aluminum. Because there is no quoted futures market price for the U.S. Midwest premium component of the market price for primary aluminum, it is necessary for management to estimate the U.S. Midwest premium. Fluctuations in the LME price of primary aluminum have a significant impact on gains and losses included in the Company’s financial statements from period to period. Unrealized gains and losses are either included in Other comprehensive income (loss) or Net gain (loss) on forward contracts, depending on criteria as provided for in the accounting standards.

      The forward natural gas purchase contracts are marked-to-market using the NYMEX spot and forward market for natural gas. Fluctuations in the NYMEX price of natural gas can have a significant impact on gains and losses included in the Company’s financial statements from period to period. The Company has designated these forward contracts as cash flow hedges for forecasted natural gas transactions in accordance with the provisions of SFAS No. 133 (as amended). The Company assesses the effectiveness of these cash flow hedges quarterly. The effective portion of the gains and losses are recorded in Other comprehensive income (loss) and subsequently reclassified into earnings when the forecasted transaction affects earnings. The ineffective portion of the gain or loss is reported in earnings immediately.

      The principal contracts affected by these standards and the resulting effects on the financial statements are described in the consolidated financial statements and related notes thereto.

Results of Operations

      The following table sets forth, for the years indicated, the percentage relationship to net sales of certain items included in the Company’s Statements of Operations. The following table includes the results from the Company’s additional 20% interest in the Hawesville facility since its acquisition in April 2003, the results from the Company’s purchase of the Nordural facility since its acquisition in April 2004 and the results from the Company’s interest in the Gramercy assets since its acquisition in October 2004.

      The following table sets forth, for the periods indicated, the pounds and the average sales price per pound shipped:

      Net sales. Net sales for the year ended December 31, 2004 increased $278.3 million or 36% to $1,061 million. Higher price realizations for primary aluminum in 2004, due to an improved LME price and Midwest premium for primary aluminum, contributed an additional $155.4 million in sales. Shipment volume increased 191.5 million pounds, primarily associated with the Nordural facility acquisition beginning in late April 2004 and the additional 20% interest in the Hawesville facility beginning in April 2003. Tolling revenues from the Nordural facility acquisition contributed an additional $85.4 million in net sales. The remaining $37.5 million increase was associated with increased direct shipment volumes.

      Gross profit. For the year ended December 31, 2004, gross profit improved $128.4 million to $176.5 million. Improved price realizations net of increased alumina costs improved gross profit by $112.6 million with increased shipment volume, primarily a result of the Nordural facility acquisition in April 2004 and the additional 20% interest in the Hawesville facility beginning in April 2003, contributing $36.8 million in additional gross profit. Offsetting these gains were increased power costs due to lower efficiencies and price, $7.7 million; reduced credits to cost of goods sold for lower-of-cost or market adjustments, $5.2 million; raw material quality issues, $4.6 million; and costs associated with the replacement of pot cells and its effect on operational performance, $3.5 million.

      Selling, general and administrative expenses. Selling, general and administrative expenses for the year ended December 31, 2004 increased $4.1 million from the same period in 2003. The increase was primarily a result of incentive compensation expense accruals and increased fees associated with Sarbanes Oxley Section 404 compliance work during the year.

      Interest expense, net: Interest expense during the year ended December 31, 2004 declined $4.3 million to $39.2 million. The change in interest expense was a direct result of the Company’s refinancing activities in the current year.

      Net gain/loss on forward contracts. For the year ended December 31, 2004, net loss on forward contracts was $21.5 million as compared to a net gain on forward contracts of $25.7 million for the same period in 2003. The loss and gain reported for the years ended December 31, 2004 and December 31, 2003,

respectively, primarily relate to the early termination in 2003 of a fixed price forward sales contract with Glencore and the improved LME price and Midwest premium for primary aluminum in the current period. See “Business – Sales and Distribution — Mt. Holly.”

      Loss on early extinguishment of debt. For the year ended December 31, 2004, the Company recorded a loss on early extinguishment of debt of $47.4 million for the one-time cost of tendering for the $325.0 million in first mortgage notes.

      Tax provision. Income tax expense for the year ended December 31, 2004 increased $12.1 million due to the changes in income before income taxes discussed above.

      Equity in earnings of joint venture: Equity in earnings from the Gramercy assets, which were acquired on October 1, 2004, was $0.8 million in the current period.

      Net sales. Net sales for the year ended December 31, 2003 increased $71.1 million or 10.0% to $782.5 million. Increased shipment volume of 77.2 million pounds in 2003, primarily associated with the additional 20% interest in the Hawesville facility beginning in April 2003, accounted for $52.4 million of the increase. Higher price realizations for primary aluminum in 2003 due to an improved LME price for primary aluminum contributed an additional $18.8 million in sales.

      Gross profit. Gross profit for the year ended December 31, 2003 increased $28.0 million or 139.5% to $48.0 million from $20.1 million for the same period in 2002. Increased shipments, primarily from the additional 20% interest in the Hawesville facility beginning in April 2003, improved gross profit by $5.7 million. The remaining $22.3 million improvement in gross profit was a result of lower depreciation and amortization charges, $5.4 million, primarily due to lower amortization charges related to the intangible asset, see Part II, Item 8, Note 1 to the “Consolidated Financial Statements,” reduced charges to cost of goods sold for lower-of-cost or market inventory adjustments, $7.3 million, and improved price realizations net of increased alumina costs, $10.2 million, other net benefits of $1.0 million, partially offset a charge for the excess cost of spot alumina purchases of $1.6 million due to a production curtailment at a supplier’s production facility.

      Selling, general and administrative expenses. Selling, general and administrative expenses for the year ended December 31, 2003 increased $5.1 million to $20.8 million. The increase was primarily a result of a $3.1 million charge related to an executive resignation in 2003. The remaining increase of $2.0 million was a result of increased incentive compensation associated with improved 2003 financial and operational results.

      Interest Expense. Interest expense during the year ended December 31, 2003 increased $3.0 million or 7.4% to $43.8 million. The change in interest expense was primarily a result of related party interest expense of $2.6 million associated with the Glencore Note.

      Other Income/ Expense. Other Expense for the year ended December 31, 2003 declined by $1.2 million primarily due to a write-off in 2002 of $1.7 million in deferred costs associated with a prospective acquisition.

      Net Gain on Forward Contracts. Net Gain on Forward Contracts for the year ended December 31, 2003 was $25.7 million with no gain or loss reported for the same period in 2002. The gain recorded in 2003 primarily relates to the early termination of a fixed price forward sales contract with Glencore. See Part I, Item 1, “Business — Sales and Distribution — Mt. Holly.”

      Tax Provision/ Benefit. Income tax provision increased $17.0 million to $2.8 million from an income tax benefit in 2002. The change in income taxes was a result of a pre-tax gain in 2003 compared to a pre-tax loss in 2002. The 2002 tax benefit was affected by a $1.5 million reduction in estimated income taxes payable relating to the reversal of prior period accruals.

      Minority Interest. Minority Interest reflects Glencore’s interest in the net operating results of Century Aluminum of Kentucky, LLC (the “LLC”), the limited liability company which holds the power contract for the Hawesville facility. The Minority Interest primarily represented the amortization of the power contract.

Minority Interest for the year ended December 31, 2003 decreased $4.3 million to $1.0 million. The decrease was a result of eliminating the minority interest in April 2003 through Century’s acquisition of Glencore’s 20% interest in the Hawesville facility.

      Cumulative Effect of Change in Accounting Principle. The Company adopted SFAS No. 143, “Accounting for Asset Retirement Obligations” on January 1, 2003. The cumulative effect of adopting this standard was a one-time, non-cash charge of $5.9 million, net of tax of $3.4 million.

Liquidity and Capital Resources

      The Company’s principal sources of liquidity are cash flow from operations and available borrowings under the Company’s revolving credit facility and Nordural’s new term loan facility. The Company’s principal uses of cash are operating costs, payments of interest on the Company’s outstanding debt, the funding of capital expenditures and investments in related businesses, working capital and other general corporate requirements.

      As of December 31, 2004, the Company had $524.1 million of indebtedness outstanding, including $9.9 million of principal under the Company’s first mortgage notes, net of unamortized issuance discount, $175.0 million of principal under the Company’s convertible notes, $250.0 million of principal under the Company’s senior notes, $7.8 million in industrial revenue bonds which were assumed in connection with the Hawesville acquisition, and $81.4 million of debt outstanding at Nordural.

      First Mortgage Notes. Interest payments on the Company’s first mortgage notes are payable semiannually in arrears beginning on October 15, 2001. Payment obligations under the notes are guaranteed by the Company’s domestic restricted subsidiaries and secured by mortgages and security interests in 80% of the real property, plant and equipment comprising the Hawesville facility and 100% of the real property, plant and equipment comprising the Ravenswood facility. The first mortgage notes are due to mature in 2008. In August 2004, the Company completed a tender offer and consent solicitation for the Company’s first mortgage notes. In connection with the consent solicitation, the Company entered into a supplemental indenture that eliminated substantially all of the restrictive covenants and certain default provisions contained in the first mortgage notes indenture. The Company purchased approximately $315.1 million in aggregate principal amount of the first mortgage notes validly tendered in the tender offer and not withdrawn. Following the purchase of the first mortgage notes accepted in the tender offer, $9.9 million in aggregate principal amount of the first mortgage notes remain outstanding. See “Management’s Discussion and Analysis — Recent Developments — The 2004 Refinancing.” The Company has provided the trustee under the indenture notice of its intent to call for redemption all outstanding first mortgage notes on or about April 15, 2005.

      Convertible Notes. Interest payments on the Company’s convertible notes are payable semiannually in arrears beginning on February 1, 2005. The Company’s obligations under the notes are guaranteed by each of the Company’s substantial existing and future domestic restricted subsidiaries if and for so long as such subsidiary guarantees the Company’s senior notes. The convertible notes are due to mature on August 1, 2024. The convertible notes are convertible at any time at an initial conversion rate of 32.7430 shares of common stock per $1,000 principal amount of notes, subject to adjustments for certain events. The initial conversion rate is equivalent to a conversion price of approximately $30.5409 per share of the Company’s common stock. Upon conversion of a convertible note, the holder will receive cash up to the aggregate principal amount of the notes to be converted, and, at the Company’s election, cash, common stock or a combination thereof in respect of the remainder, if any, of the Company’s conversion obligation in excess of the principal amount. The convertible notes are redeemable at the Company’s option beginning on August 6, 2009. The holders may require the Company to repurchase all or part of their convertible notes on each of August 1, 2011, August 1, 2014 and August 1, 2019. The convertible notes are classified as current because they are convertible at any time.

      Senior Notes. Interest payments on the Company’s senior notes are payable semiannually in arrears beginning on February 15, 2005. The senior notes are guaranteed by each of the Company’s substantial

existing and future domestic restricted subsidiaries. The senior notes are due to mature on August 15, 2014. The indenture governing the Company’s senior notes contains customary covenants, including limitations on the Company’s ability to incur additional indebtedness, pay dividends, sell assets or stock of certain subsidiaries and purchase or redeem capital stock. The Company agreed to file and cause to become effective a registration statement to exchange the senior notes for new notes in a transaction registered under the Securities Act. On February 11, 2005, the exchange offer registration statement filed by the Company was declared effective. On March 14, 2005, the exchange offer period expired. All of the Company’s 7.5% Senior Notes due August 15, 2014 were exchanged in the exchange offer. The terms of the exchange notes are substantially identical to the senior notes, except that the exchange notes are not subject to transfer restrictions.

      Revolving Credit Facility. Effective April 1, 2001, the Company entered into a $100.0 million senior secured revolving credit facility with a syndicate of banks. The revolving credit facility will mature on April 2, 2006. The Company’s obligations under the revolving credit facility are guaranteed by each of the Company’s substantial existing domestic subsidiaries and secured by a first priority security interest in all accounts receivable and inventory belonging to the Company and the Company’s subsidiary borrowers. The availability of funds under the revolving credit facility is subject to a $30.0 million reserve and limited by a specified borrowing base consisting of certain eligible accounts receivable and inventory. Borrowings under the revolving credit facility are, at the Company’s option, at the LIBOR or the Fleet National Bank base rate plus, in each case, an applicable interest margin. The applicable interest margin ranges from 2.25% to 3.0% over the LIBOR rate and 0.75% to 1.5% over the base rate and is determined by certain financial measurements of us. There were no outstanding borrowings under the revolving credit facility as of December 31, 2004 and December 31, 2003. Interest periods for LIBOR rate borrowings are one, two, three or six months, at the Company’s option. The Company measures the Company’s borrowing base at month-end. At December 31, 2004, the Company had a borrowing base of $87.9 million under the revolving credit facility. The Company is subject to customary covenants, including limitations on capital expenditures, additional indebtedness, liens, guarantees, mergers and acquisitions, dividends, distributions, capital redemptions and investments.

      Glencore Note Payable. In April 2004, the Company repaid the remaining $14.0 million of outstanding principal on a six-year $40.0 million promissory note payable to Glencore that was issued on April 1, 2003 in connection with the Company’s acquisition of the remaining 20% interest in the Hawesville facility. The payment consisted of a $2.0 million required principal payment and an optional $12.0 million prepayment of principal. The Glencore note bore interest at a rate of 10% per annum and was due to mature on April 1, 2009.

      Industrial Revenue Bonds. Effective April 1, 2001, as part of the purchase price for the Hawesville acquisition, the Company assumed industrial revenue bonds, or IRBs, in the aggregate principal amount of $7.8 million which were issued in connection with the financing of certain solid waste disposal facilities constructed at the Hawesville facility. From April 1, 2001 through April 1, 2003, Glencore assumed 20% of the liability related to the IRBs consistent with its ownership interest in the Hawesville facility during that period. The IRBs mature on April 1, 2028, and bear interest at a variable rate not to exceed 12% per annum determined weekly based upon prevailing rates for similar bonds in the industrial revenue bond market. Interest on the IRBs is paid quarterly. At December 31, 2004, the interest rate on the IRBs was 2.30%. The IRBs are classified as current liabilities because they are remarketed weekly and, under the indenture governing the IRBs, repayment upon demand could be required if there is a failed remarketing. The IRBs are secured by a Glencore guaranteed letter of credit. The Company has agreed to reimburse Glencore for all costs arising from the letter of credit and have secured the reimbursement obligation with a first priority security interest in the 20% interest in the Hawesville facility. The Company’s maximum potential amount of future payments under the reimbursement obligations for the Glencore letter of credit securing the IRBs would be approximately $8.2 million.

      Nordural’s Term Loan Facility. At December 31, 2004 Nordural had $68.5 million of debt outstanding under its then existing $185 million loan facility. On February 10, 2005, Nordural executed agreements and documents related to a new $365.0 million senior term loan facility arranged by Landsbanki Islands hf. and Kaupthing Bank hf. The new term loan facility closed and funded on February 15, 2005. Amounts borrowed under the new term loan facility refinanced debt under Nordural’s former term loan facility, and will be used

to finance a portion of the costs associated with the ongoing expansion of the Nordural facility and for Nordural’s general corporate purposes. Amounts borrowed under Nordural’s new term loan facility generally will bear interest at a margin over the applicable Eurodollar rate, plus any increased cost of compliance by the lenders with any applicable reserve asset requirements. Nordural’s obligations under the new term loan facility have been secured by a pledge of all of Nordural’s shares pursuant to a share pledge agreement with the lenders. In addition, substantially all of Nordural’s assets are pledged as security under the loan facility. Nordural is required to make the following minimum repayments of principal on the facility: $15.5 million on February 28, 2007 and $14.0 million on each of August 31, 2007, February 29, 2008, August 31, 2008, February 28, 2009, August 31, 2009 and February 28, 2010. If Nordural makes a dividend payment (which dividends are not permitted until the Nordural facility has been expanded to a production level of 212,000 metric tons per year), it must simultaneously make a repayment of principal in an amount equal to 50% of the dividend. The new term loan facility is non-recourse to Century Aluminum Company. All outstanding principal must be repaid at final maturity on February 28, 2010.

      Nordural’s loan facility contains customary covenants, including limitations on additional indebtedness, investments, capital expenditures (other than related to the expansion project), dividends, and hedging agreements. Nordural is also subject to various financial covenants, including a net worth covenant and certain maintenance covenants, including minimum interest coverage and debt service coverage beginning as of December 31, 2004.

      In connection with the Hawesville acquisition, the Company issued $25.0 million of the Company’s convertible preferred stock to Glencore. The Company was required to pay dividends on the preferred stock at a rate of 8% per year, which was cumulative (see Item 8 Consolidated financial statements, Note 8). In accordance with accounting guidance, no liability for cumulative preferred dividends was recorded until the dividends were declared. In May 2004, the Company used proceeds from the Company’s April 2004 equity offering to pay $3.3 million in dividend arrearages on the Company’s convertible preferred stock. Subsequent to the dividend payment in May 2004, Glencore converted the 500,000 shares of the Company’s convertible preferred stock it owned into 1,395,089 shares of the Company’s common stock, representing a conversion price of $17.92 per share. The conversion was effected in accordance with the terms of the Certificate of Designation for the preferred stock.

      The Company had negative working capital of $103.4 million at December 31, 2004, primarily because the convertible notes are classified as current liabilities. Excluding the convertible notes, working capital would have been $71.6 million.

      The Company’s working capital increased modestly with the acquisition of Nordural in April 2004 and a further proportionate increase is expected as the Nordural expansion comes on line in 2006. With the exception of Nordural, the Company does not anticipate significant changes in working capital. The Company believes that cash flow from operations and borrowing availability under the revolving credit facility will be sufficient to meet working capital needs.

      Capital expenditures for 2004 were $75.0 million, $59.8 million of which was related to the expansion project at the Nordural facility, with the balance principally related to upgrading production equipment, maintaining facilities and complying with environmental requirements. The revolving credit facility limits the Company’s ability to make capital expenditures at its U.S. reduction facilities; however, the Company believes that the amount permitted will be adequate to maintain its properties and business and comply with environmental requirements. The Company anticipates capital expenditures of approximately $20.0 million in 2005, exclusive of the Nordural expansion. The Nordural expansion will require approximately $320.0 million of capital expenditures in 2005. Through December 31, 2004, the Company had outstanding capital

commitments related to the Nordural expansion of $218.8 million. The Company’s cost commitments for the Nordural expansion may materially change depending on the exchange rate between the U.S. dollar and certain foreign currencies, principally the euro and the Icelandic krona. Approximately 64% of the expected project costs for the Nordural expansion are denominated in currencies other than the U.S. dollar, primarily the euro and the krona. As of December 31, 2004, the Company had no hedges to mitigate the Company’s foreign currency exposure. See “Management’s Discussion and Analysis — Recent Developments — Nordural Acquisition and Expansion.”

      The Company’s strategic objectives are to grow the Company’s aluminum business by acquiring primary aluminum reduction facilities that offer favorable investment returns and lower the Company’s unit production costs, to diversify the Company’s geographic presence, and to pursue opportunities in bauxite mining and alumina refining. The Company anticipates that operating cash flow, together with borrowings under the revolving credit facility and the Nordural term loan facility, will be sufficient to meet its future debt service obligations as they become due, as well as working capital and capital expenditures requirements. The Company’s ability to meet its liquidity needs, including any and all of its debt service obligations, will depend upon the Company’s future operating performance, which will be affected by general economic, financial, competitive, regulatory, business and other factors, many of which are beyond the Company’s control. The Company will continue from time to time to explore additional financing methods and other means to lower its cost of capital, including stock issuances or debt financing and the application of the proceeds to the repayment of bank debt or other indebtedness.

      The Company’s Statements of Cash Flows for the years ended December 31, 2004, 2003 and 2002 are summarized below:

      Net cash from operating activities of $105.8 million in 2004 was $18.4 million higher than the same period in 2003. Exclusive of the $35.5 million settlement received in 2003 from the termination of the Original Sales Contract and entering into the New Sales Contract with Glencore for the years 2005 through 2009 and the $50.3 million cash payment in 2004 for the tender premium plus accrued interest for the refinancing of the Company’s first mortgage notes, net cash from operating activities increased $104.2 million in 2004. This increase was a direct result of improved price realizations and the added margin contributions from the Nordural facility which was acquired in April 2004.

      Net cash from operating activities in 2003 increased $32.9 million to $87.4 million from the 2002 level. The increase in 2003 was primarily the result of the $35.5 million first quarter termination and settlement of the Original Sales Contract as discussed in Part I, Item 1, “Business — Sales and Distribution.” Gross profit associated with increased shipments of 77.2 million pounds, mainly the result of the April 1, 2003 acquisition of the 20% interest in the Hawesville facility, improved cash provided from operating activities by an additional $5.6 million. Reduced tax refunds of $8.1 million and increased cash payments for interest of $2.0 million, primarily associated with the Glencore Note, partially offset the favorable change in cash from operating activities discussed above.

      The Company’s net cash used in investing activities in 2004 was $275.3 million, an increase of $196.6 million from 2003. The net acquisition cost of the Nordural facility in April 2004 and the Gramercy assets in October 2004 was $198.6 million as compared to the net acquisition cost for the additional 20% interest in the Hawesville facility in April 2003 of $59.8 million. Purchases of property, plant and equipment,

including the Nordural expansion costs, were $75.0 million in 2004 as compared to the 2003 purchases of property, plant and equipment of $18.9 million.

      The Company’s net cash used in investing activities was $78.7 million in 2003, consisting of $59.8 million for the acquisition of the 20% interest in the Hawesville facility and $18.9 million of capital expenditures. The use of cash for investing activities in 2002 consisted primarily of capital expenditures.

      Net cash provided by financing activities during 2004 was $185.4 million, an increase of $211.0 million from the previous year. The increase was primarily due to the issuance of $425.9 million of debt, and the issuance of $215.8 million of common stock. This increase was partially offset by debt repayments of $439.9 million, consisting of payments of $315.1 million for the first mortgage notes tendered in a debt refinancing, $106.9 million for the Nordural term loan facility, the $14.0 million repayment of Glencore note debt, and $3.9 million for other miscellaneous debt payments. Additionally, the Company paid $13.1 million of financing fees for the debt issued in the fourth quarter of 2004 and $3.3 million payment of accrued preferred dividends in the second quarter of 2004.

      Net cash used in financing activities in 2003 was a result of paying $26.0 million on the Glencore Note. The cash used for financing activities in 2002 related primarily to common and preferred stock dividend payments made during the year.

      The Company believes that cash flow from operations, its unused revolving credit facility, and Nordural’s new term loan facility will provide sufficient liquidity to meet working capital needs, fund capital improvements and the planned expansion at Nordural, and provide for the debt service requirements.

Contractual Obligations

      In the normal course of business, the Company has entered into various contractual obligations that will be settled in cash. These obligations consist primarily of long-term debt obligations and purchase obligations. The expected future cash flows required to meet these obligations are shown in the table below. The purchase obligations consist of long-term supply contracts for alumina and electrical power. The Other long-term liabilities include pension, SERB, other postretirement benefits, workers’ compensation liabilities, asset retirement obligations and estimated deferred tax payments. More information is available on these contractual obligations in Part II, Item 8, “Consolidated Financial Statements.”

Environmental Expenditures and Other Contingencies

      The Company has incurred and in the future will continue to incur capital expenditures and operating expenses for matters relating to environmental control, remediation, monitoring and compliance. The aggregate environmental related accrued liabilities were $0.6 million and $0.7 million at December 31, 2004 and December 31, 2003, respectively. The Company believes that compliance with current environmental laws and regulations is not likely to have a material adverse effect on the Company’s financial condition, results of operations or liquidity; however, environmental laws and regulations may change, and the Company may become subject to more stringent environmental laws and regulations in the future.

      The Company has planned environmental capital expenditures of approximately $0.6 million for 2005, $1.3 million for 2006 and $0.4 million for 2007. In addition, the Company expects to incur operating expenses relating to environmental matters of approximately $9.9 million, $10.7 million, and $11.0 million in 2005, 2006 and 2007, respectively. These amounts do not include any projected capital expenditures or operating expenses for the Company’s joint venture interest in the Gramercy assets, which have not yet been determined. See Part I, Item 1 “Environmental Matters.” As part of the Company’s general capital expenditure plan, it also expects to incur capital expenditures for other capital projects that may, in addition to improving operations, reduce certain environmental impacts. See Part I, Item 1 “Environmental Matters.”

      The Company’s income tax returns are periodically examined by various tax authorities. The Company is currently under audit by the Internal Revenue Service (“IRS”) for the tax years through 2002. In connection with such examinations, the IRS has raised issues and proposed tax deficiencies. The Company is reviewing the issues raised by the IRS and plans to contest the proposed tax deficiencies. The Company believes that its tax position is well-supported and, based on current information, does not believe that the outcome of the tax audit will have a material impact on the Company’s financial condition or results of operations.

      The Company is a defendant in several actions relating to various aspects of its business. While it is impossible to predict the ultimate disposition of any litigation, the Company does not believe that any of these lawsuits, either individually or in the aggregate, will have a material adverse effect on the Company’s financial condition, results of operations or liquidity. See Item 3, “Legal Proceedings.”

New Accounting Standards

      In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123(R), “Share Based Payment.” This Statement is a revision of FASB Statement No. 123, “Accounting for Stock-Based Compensation” and supersedes Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees.” This statement focuses primarily on accounting for transactions in which a company obtains employee services in share-based payment transactions. This Statement will require the Company to recognize the grant date fair value of an award of equity-based instruments to employees and the cost will be recognized over the period in which the employees are required to provide service. The Statement is effective for the first interim period beginning after June 15, 2005. The Company is currently assessing the Statement and does not expect the impact of adopting SFAS No. 123(R) to have a material effect on the Company’s financial position and results of operations.

      In November 2004, the FASB issued SFAS No. 151, “Inventory Costs.” This Statement amends the guidance in Accounting Research Bulletin No. 43, Chapter 4, “Inventory Pricing” to clarify the accounting treatment for certain inventory costs. In addition, the Statement requires that the allocation of production overheads be based on the facilities’ normal production capacity. This Statement is effective for financial statements issued for fiscal years beginning after June 15, 2005. The Company is currently assessing the Statement and has not yet determined the impact of adopting SFAS No. 151 on the Company’s financial position and results of operations.

      On December 8, 2003, the “Medicare Prescription Drug Improvement and Modernization Act of 2003,” or the Medicare Act, was signed into law. The Medicare Act introduces a prescription drug benefit under Medicare as well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least “actuarially equivalent” to Medicare Part D.

      In the second quarter of 2004, an FASB Staff Position (FSP FAS 106-2, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug Improvement and Modernization Act of 2003”) was issued providing guidance on the accounting for the effects of the Medicare Act for employers that sponsor postretirement health care plans that provide prescription drug benefits. This FSP superseded FSP FAS 106-1, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug Improvement and Modernization Act of 2003.” The FSP is effective for the first interim or annual period beginning after June 15, 2004.

      The guidance in this FSP applies only to the sponsor of a single-employer defined benefit postretirement health plan for which the employer has concluded that prescription drug benefits available under the plan are actuarially equivalent and thus qualify for the subsidy under the Medicare Act and the expected subsidy will offset or reduce the employer’s share of the costs of postretirement prescription drug coverage provided by the plan. The Company determined that the Company’s plans were actuarially equivalent and elected to adopt the provisions of FSP FAS 106-2 in the third quarter of 2004 on a prospective basis only. The Company compared the Medicare Part D plan to its retiree prescription drug coverage using actuarial equivalencies and reflecting the retiree premiums and cost sharing provisions of the various plans. This analysis showed the Company’s plans provide more valuable benefits to retirees than the Medicare Part D plan. Based on the Company’s understanding of the intent of the Medicare Act and subsequent proposed regulations, the Company still believes the Company’s plans will meet the actuarial equivalence requirements necessary to receive the Medicare reimbursement.

      For retirees with post-65 prescription drug benefits, the Company estimates the net effect on post-65 per capita medical and prescription drug costs to be a reduction of approximately 11% to 14% due to the Medicare reimbursement. The changes are assumed to have no impact on future participation rates in the Company’s post-65 prescription drug programs.

Commodity Prices

      The Company is exposed to the price of primary aluminum. The Company manages its exposure to fluctuations in the price of primary aluminum by selling aluminum at fixed prices for future delivery and through financial instruments as well as by purchasing alumina under supply contracts with prices tied to the same indices as the Company’s aluminum sales contracts. See Part II, Item 7, “Management’s Discussion and Analysis — Key Long-Term Supply Agreements.” The Company’s risk management activities do not include trading or speculative transactions.

      Apart from the contracts described under “Key Long-Term Primary Aluminum Sales Contracts,” the Company had forward delivery contracts to sell 196.7 million pounds and 351.8 million pounds of primary aluminum at December 31, 2004 and December 31, 2003, respectively. Of these forward delivery contracts, the Company had fixed price commitments to sell 13.6 million pounds and 70.5 million pounds of primary aluminum at December 31, 2004 and December 31, 2003, respectively, of which, none at December 31, 2004 and 53.5 million pounds at December 31, 2003, were with Glencore.

      At December 31, 2004 and December 31, 2003, the Company had fixed price financial sales contracts, primarily with Glencore, for 1,686.4 million pounds and 102.9 million pounds of primary aluminum, respectively, of which 1,023.7 million pounds and 58.8 million pounds, respectively, were designated cash flow hedges. Certain of these sales contracts contain clauses that trigger additional shipment volume when the market price for a period is above the contract ceiling price for that period. These contracts are evaluated monthly and the maximum additional shipment volume over the life of the contract would be 662.7 million pounds, if the market price exceeded the ceiling price for all months during the term of the contract. These fixed price financial sales contracts are scheduled for settlement at various dates in 2005 through 2010. The Company had no fixed price financial purchase contracts to purchase aluminum at December 31, 2004 or December 31, 2003.

Fixed Price Financial Sales Contracts at

December 31, 2004:

Primary Aluminum

      Additionally, to mitigate the volatility of the natural gas markets, the Company enters into fixed price financial purchase contracts, accounted for as cash flow hedges, which settle in cash in the period corresponding to the intended usage of natural gas.

Fixed Price Financial Purchase Contracts at

December 31, 2004:

Natural Gas

      At December 31, 2004 and December 31, 2003, the Company had fixed price financial purchase contracts for 4.3 million and 2.7 million DTH (one decatherm is equivalent to one million British Thermal Units), respectively. These financial instruments are scheduled for settlement at various dates in 2005 through 2008.

      On a hypothetical basis, a $0.01 per pound increase or decrease in the market price of primary aluminum is estimated to have an unfavorable or favorable impact of $6.5 million after tax on accumulated other comprehensive income for the contracts designated as cash flow hedges, and $4.2 million on net income, for the contracts designated as derivatives, for the year ended December 31, 2004 as a result of the forward primary aluminum financial sales contracts outstanding at December 31, 2004.

      On a hypothetical basis, a $0.50 per DTH decrease or increase in the market price of natural gas is estimated to have an unfavorable or favorable impact of $1.4 million after tax on accumulated other comprehensive income for the year ended December 31, 2004 as a result of the forward natural gas financial purchase contracts outstanding at December 31, 2004.

      The Company’s metals and natural gas risk management activities are subject to the control and direction of senior management. The metals related activities are regularly reported to the Company’s board of directors.

      This quantification of the Company’s exposure to the commodity price of aluminum is necessarily limited, as it does not take into consideration the Company’s inventory or forward delivery contracts, or the offsetting impact on the sales price of primary aluminum products. Because all of the Company’s alumina contracts, except the GAL Alumina contract for the Hawesville facility, are indexed to the LME price for aluminum, beginning in 2002, they act as a natural hedge for approximately 12% of the Company’s production. As of December 31, 2004, approximately 49% and 43% of the Company’s production for the years 2005 and 2006, respectively, was either hedged by the alumina contracts, Nordural electrical power and tolling contracts, and/or by fixed price forward delivery and financial sales contracts.

      Nordural. Substantially all of Nordural’s revenues are derived from the Billiton Tolling Agreement whereby it converts alumina provided to it into primary aluminum for a fee based on the LME price for primary aluminum. Nordural’s revenues are subject to the risk of decreases in the market price of primary aluminum; however, Nordural is not exposed to increases in the price for alumina, the principal raw material used in the production of primary aluminum. In addition, under its current power contract, Nordural purchases power at a rate which is a percentage of the LME price for primary aluminum, providing Nordural with a natural hedge against downswings in the market for primary aluminum.

      Nordural is exposed to foreign currency risk due to fluctuations in the value of the U.S. dollar as compared to the euro and the Icelandic krona. Under its Billiton Tolling Agreement and power contracts, Nordural’s revenues and power costs are based on the LME price for primary aluminum, which is denominated in U.S. dollars. There is no currency risk associated with these contracts. Nordural’s labor costs are denominated in Icelandic krona and a portion of its anode costs are denominated in euros. As a result, an increase or decrease in the value of those currencies relative to the U.S. dollar would affect Nordural’s operating margins.

Interest Rates

      Interest Rate Risk. The Company’s primary debt obligations are the outstanding senior notes, convertible notes, first mortgage notes, the Nordural debt, borrowings under the revolving credit facility, if any, and the IRBs. Because the senior notes, convertible notes and first mortgage notes bear a fixed rate of interest, changes in interest rates do not subject the Company to changes in future interest expense with respect to these borrowings. Borrowings under the revolving credit facility, if any, are at variable rates at a margin over LIBOR or the Fleet National Bank base rate, as defined in the revolving credit facility. The IRBs bear interest at variable rates determined by reference to the interest rate of similar instruments in the industrial revenue bond market. At December 31, 2004, Nordural had approximately $75.7 million of long-term debt consisting primarily of obligations under its then existing term loan facility. Borrowings under Nordural’s term loan

facility in place as of December 31, 2004 bore interest at a margin over the applicable LIBOR rate. On February 10, 2005, the Company executed agreements and documents related to a new $365.0 million senior term loan facility arranged by Landsbanki Islands hf. and Kaupthing Bank hf. The new term loan facility closed and funded on February 15, 2005, at which time a portion of the proceeds of the new facility were used to refinance the prior loan facility. See Item 7 “Management’s Discussion and Analysis — Recent Developments — Nordural’s New Term Loan Facility.” Borrowings under Nordural’s new term loan facility bear interest at a margin over the applicable Eurodollar rate.

      At December 31, 2004, the Company had $76.3 million of variable rate borrowings. A hypothetical one percentage point increase in the interest rate would increase the Company’s annual interest expense by $0.8 million, assuming no debt reduction.

      The Company’s primary financial instruments are cash and short-term investments, including cash in bank accounts and other highly rated liquid money market investments and government securities.
