Overview
Century Aluminum Company is a global producer of primary aluminum and operates aluminum reduction facilities, or "smelters," in the United States and Iceland. Aluminum is an internationally traded commodity, and its price is effectively determined on the London Metal Exchange (the "LME"), plus applicable regional and value-added product premiums. Our smelters produce standard-grade and value-added primary aluminum products. Our current annual production capacity is approximately 1,020,000 tonnes per year ("tpy"), of which approximately 308,000 tpy was curtailed as of December 31, 2024 . We produced approximately 690,000 tonnes of primary aluminum in 2024.
In addition to our primary aluminum assets, we have a 55% joint venture interest in the Jamalco bauxite mining operation and alumina refinery in Jamaica ("Jamalco"). The remaining 45% interest in Jamalco is indirectly owned by the Government of Jamaica. Century's share of Jamalco's production capacity is approximately 770,000 tpy. The Jamalco refinery supplies a substantial amount of the alumina used for production of primary aluminum at our aluminum smelter in Grundartangi, Iceland. We also own a carbon anode production facility located in the Netherlands ("Vlissingen"). Carbon anodes are consumed in the production of primary aluminum. Vlissingen supplies carbon anodes to our aluminum smelter in Grundartangi, Iceland. Each of our aluminum smelters in the United States produces anodes at on-site facilities.
At Century, we aim to provide innovative and reliable aluminum products to our customers, a safe and sustainable workplace for our people and the communities in which we operate, and a compelling value proposition for our stockholders. We seek to operate our businesses in a responsible manner by balancing the twin priorities of (i) maintaining a strong balance sheet across commodity cycles and (ii) making investments to lower our cost structure, expand our production capacity, and increase our competitiveness.
Century has invested significant capital in recent years to increase production and grow our product portfolio to include more value-added aluminum products to better serve our customers in the U.S. and Europe. We believe that our focus on lowering costs and decommoditizing our product line will enable us to deliver profitable long-term growth and differentiate us from overseas competitors with longer supply lines into the markets we serve.
We conduct our business with a focus on sustainability, including the health and safety of our people and the communities in which we operate. Through our Natur-Al TM product line, we are able to provide our customers with world-class, low-carbon aluminum products that demonstrate our commitment to sustainability.
We operate our business through one reportable segment, primary aluminum. Additional information about our segment reporting and certain geographic information is available in Note 19. Business Segments to the consolidated financial statements included herein.
Century Aluminum Company is a Delaware corporation with our principal executive offices located at One South Wacker Drive, Suite 1000, Chicago, Illinois 60606.
Primary Aluminum Facilities
Overview of Facilities
We operate three U.S. aluminum smelters, in Hawesville, Kentucky ("Hawesville"), currently curtailed, Robards, Kentucky ("Sebree") and Goose Creek, South Carolina ("Mt. Holly"), and one aluminum smelter in Grundartangi, Iceland ("Grundartangi").

Our primary aluminum smelters and their respective primary aluminum capacities are shown in the following table:
Facility Ownership Percentage Operational Annual Production Capacity (tpy) (1)
Actual 2024 Annual Production (tpy)
Grundartangi, Iceland 100% 1998 320,000 309,000
Hawesville, Kentucky, USA 100% 1970 250,000 —
Sebree, Kentucky, USA 100% 1973 220,000 216,000
Mt. Holly, South Carolina, USA 100% 1980 230,000 165,000
1,020,000 690,000
(1) The tonnes per year (tpy) figures in this column reflect an estimate of the facility's total production capacity based on plant design, historical operating results and operating efficiencies and does not necessarily represent each facility’s maximum production capability.
Grundartangi
The Grundartangi facility, located in Grundartangi, Iceland, is a primary aluminum smelter owned and operated by our wholly-owned subsidiary, Nordural Grundartangi ehf. Grundartangi is our most modern facility with a current production capacity of approximately 320,000 tonnes. Grundartangi produces standard-grade aluminum ingot and a value-added product called primary foundry alloy, which is sold at a premium to standard-grade aluminum.
In 2024, Century completed construction of a new billet casthouse at Grundartangi (the “Casthouse Project”). The new billet casthouse has the capacity to produce 150,000 tonnes of value-added billet. The Casthouse Project will also increase Grundartangi’s annual capacity to produce value-added primary foundry alloys from 60,000 tonnes of capacity to 120,000 tonnes of capacity. This incremental billet and primary foundry alloy capacity displaces standard-grade ingot production, raising expected total value-added product premiums for Grundartangi products. The billet produced at the Grundartangi casthouse is expected to be Natur-Al TM branded billet, our low-carbon aluminum brand .
Hawesville
Hawesville, located adjacent to the Ohio River near Hawesville, Kentucky, is a primary aluminum smelter owned by our wholly-owned subsidiary, Century Kentucky, Inc. ("CAKY"). Hawesville has an annual production capacity of approximately 250,000 tonnes of primary aluminum. In August 2022, we fully curtailed production at the Hawesville facility. We continue to explore all options related to the Hawesville facility, and have engaged financial advisors and launched a formal process to evaluate strategic alternatives and potential value to help us in our overall evaluation of this asset .
Sebree
Sebree, located adjacent to the Green River near Robards, Kentucky, is a primary aluminum smelter owned and operated by our wholly-owned subsidiary, Century Aluminum Sebree LLC ("Century Sebree"). Sebree has an annual production capacity of approximately 220,000 tonnes of primary aluminum. Sebree produces standard-grade aluminum that can be cast into sow and value-added products, including billet, that are sold at a premium to standard-grade aluminum or delivered directly to nearby customers as molten metal.
Mt. Holly
Mt. Holly, located in Goose Creek, South Carolina, is a primary aluminum smelter owned and operated by our wholly-owned subsidiary, Century Aluminum of South Carolina, Inc. ("CASC"). Mt. Holly has an annual production capacity of approximately 230,000 tonnes of primary aluminum. In December 2020, we began a multi-year project to restore previously curtailed capacity at Mt. Holly. The initial phase was completed in 2022 and returned annual active production capacity to approximately 172,000 MT per annum (75% of capacity). Any potential future restart of Mt. Holly's curtailed capacity will be made in the context of then-current market conditions
Mt. Holly produces standard-grade aluminum that is cast into sow as well as several value-added products, including billet and foundry products. These value-added primary aluminum products are sold at a premium to standard-grade aluminum.

Primary Aluminum Shipment Volume
The following table shows our primary aluminum shipment volumes since 2020.
Carbon Anode Production Facility
Vlissingen
In addition to our primary aluminum assets, we own a carbon anode production facility located in Vlissingen, Netherlands, which is owned and operated by our wholly-owned subsidiary, Century Aluminum Vlissingen B.V. Vlissingen has an annual carbon anode production capacity of approximately 163,000 tonnes. Vlissingen supplies anodes primarily to our Grundartangi smelter, meeting 93% to 98% of Grundartangi’s carbon anodes requirements at current production levels. Each of our smelters in the United States produces anodes at on-site facilities.
Bauxite Mining and Alumina Refining Facility
Jamalco
In May 2023, our wholly-owned subsidiary, Century Aluminum Jamaica Holdings, Inc., completed the acquisition of all the outstanding share capital of General Alumina Holdings Limited, the holder of a 55% interest in Jamalco, an unincorporated joint venture with the Government of Jamaica through its controlled entity Clarendon Alumina Production Limited ("CAP"). Jamalco is engaged in bauxite mining and alumina refining in Jamaica. The Company's wholly-owned subsidiary, General Alumina Jamaica Limited, is the managing partner of the Jamalco joint venture. Jamalco has alumina production capacity of approximately 1.4 million tonnes, and produced approximately 1.1 million tonnes of alumina in 2024 and approximately 1.0 million tonnes of alumina in 2023. Refer to Note 2. Acquisition of Jamalco for further information.

Pricing
Pricing for primary aluminum products is typically comprised of three components: (i) the base commodity price, which is based on quoted prices on the LME, plus (ii) any regional premium (e.g., the Midwest premium for metal sold in the United States and the European Duty Paid premium for metal sold into Europe) plus (iii) any value-added product premium. Our operating results are highly sensitive to changes in the LME price of primary aluminum and the amount of regional premiums and value-added product premiums. As a result, from time to time, we assess the appropriateness of mitigating the effects of fluctuations in the aluminum price through the use of fixed-price commitments, LME-linked supply contracts and other financial instruments. See Item 7A. Quantitative and Qualitative Disclosures about Market Risk for further discussion of how we manage our exposure to market risk.
Customer Base
We have historically derived substantially all of our consolidated net sales of primary aluminum from a small number of customers. For the year ended December 31, 2024, we derived approximately 59.1% of our consolidated sales from Glencore plc and its affiliates (together, "Glencore"). Glencore purchased aluminum produced at our U.S. smelters at prices based on the LME price for primary aluminum plus the Midwest premium plus any additional market-based product premiums. Glencore also purchased aluminum produced at our Grundartangi, Iceland smelter at prices based on the LME plus the European Duty Paid premium plus any additional market-based product premiums. We have also entered into agreements with Glencore pursua nt to which we sell certain amounts of alumina at market-based prices.
Glencore beneficially owns 42.9% of our outstanding common stock (45.8% on a fully diluted basis). See Note 4. Related Party Transactions to the consolidated financial statements included herein for additional information concerning our relationship with Glencore. We currently have agreements in place to sell a substantial portion of our 2025 production to Glencore. We expect that the rest of our 2025 customer base will remain fairly concentrated among a small number of customers under short-term contracts.
Key Production Costs
Alumina, electrical power, carbon products, labor, and other controllable costs are the principal components of our cost of production. These components together represented over 76% of our cost of goods sold for the year ended December 31, 2024. For a description of certain risks related to our raw materials, electrical power, labor and other key supplies, see Item 1A. Risk Factors in this Annual Report on Form 10-K.
Alumina Supply Agreements
For the year ended December 31, 2024, approximately 327,000 tonnes, or 30% of Jamalco's alumina production, was sold to our aluminum smelters. For the period from May 2, 2023 to December 31, 2023 approximately 287,000 tonnes, or 42% of Jamalco's alumina production was sold to Grundartangi. Our historical financial statements for periods prior to May 2, 2023 do not include the results of Jamalco.

From time to time, we may enter into forward contracts or other hedging arrangements to mitigate our electrical power or natural gas price risk. The paragraphs below summarize the sources of power and the long-term power arrangements for each of our operations.
Grundartangi. Power is currently supplied to Grundartangi from hydroelectric and geothermal sources under long-term power purchase agreements with three separate power suppliers - HS, Landsvirkjun and OR. These power purchase agreements expire on various dates from 2026 through 2036 (subject to extension). The power purchase agreements with each of HS and OR provide power at LME-based variable rates for the duration of these agreements. The larger Landsvirkjun agreement provides for fixed rates with an additional variable rate linked to the LME. Grundartangi also has a separate 25 MW power purchase agreement with Landsvirkjun at LME-based variable rate. Historically, all of the power supplied to Grundartangi has been delivered at prices indexed to the price of primary aluminum. Each power purchase agreement contains take-or-pay obligations with respect to a significant percentage of the total committed and available power under such agreement.
Hawesville. CAKY has a power supply arrangement with Kenergy and Century Marketer, LLC (“Century Marketer"), Century's wholly-owned subsidiary that acts as a Midcontinent Independent System Operator ("MISO") market participant. Under this arrangement, Hawesville gets access to power at MISO pricing plus transmission and other costs. As the MISO Market Participant, Century Marketer purchases power from MISO for resale to Kenergy, which then resells the power to Hawesville. Century Marketer's power supply arrangement with Kenergy has an effective term through May 31, 2028, with automatic one-year extensions unless either party provides one-year notice of termination prior to the May 31 anniversary date. Similarly, Kenergy's power supply contract with Hawesville has a term through December 31, 2026, with automatic one-year extensions unless either party provides one-year notice of termination prior to the December 31 anniversary date.
Sebree. Century Sebree has a power supply arrangement with Kenergy and Century Marketer. Under this arrangement, Sebree gets access to power at MISO pricing plus transmission and other costs. As the MISO Market Participant, Century Marketer purchases power from MISO for resale to Kenergy, which then resells the power to Sebree. Century Marketer's power supply arrangement with Kenergy has an effective term through May 31, 2028, with automatic one-year extensions unless either party provides one-year notice of termination prior to the May 31 anniversary date. Similarly, Kenergy's power supply contract with Sebree has a term through December 31, 2026, with automatic one-year extensions unless either party provides one-year notice of termination prior to the December 31 anniversary date.
Mt. Holly. CASC has a power supply agreement with Santee Cooper that has an effective term through December 2026. Under this power supply agreement, 100% of Mt. Holly’s electrical power requirements are supplied from Santee Cooper’s generation at service-based rates. The contract provides sufficient power to allow Mt. Holly to operate at its current production capacity, as well as an option to take additional power to support any future restart of the remaining 25% of production capacity.
See Note 17. Commitments and Contingencies to the consolidated financial statements included herein for additional information concerning our power arrangements.

We attend recruiting events at local colleges and institutes in our communities and offer educational opportunities to our employees to help them develop additional skills and knowledge and continue the process of developing leaders within Century's ranks.
Labor Agreements
The bargaining unit employees at our Grundartangi, Vlissingen, Hawesville, Sebree and Jamalco facilities are represented by labor unions, representing 59% of our total workforce. Our employees at Mt. Holly are not represented by a labor union.
A summary of our key labor agreements is provided below:
Facility Organization Term
Grundartangi Icelandic labor unions Through December 31, 2024
Hawesville United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union (“USW”)
Through April 1, 2026
Sebree USW Through October 28, 2028
Vlissingen Federation for the Metal and Electrical Industry (“FME”)
Through December 31, 2025
Jamalco Union of Technical, Administrative, and Supervisory Personnel ("UTASP")
Through December 31, 2023
Approximately 86% of Grundartangi’s workforce is represented by five labor unions, governed by a labor agreement that establishes wages and work rules for covered employees. This agreement was effective through December 31, 2024. Grundartangi is currently in the process of negotiating a new contract. Until a new contract is reached, employees will continue to operate under the current agreement.

100% of Vlissingen's work force is represented by the Federation for the Metal and Electrical Industry ("FME"), a Netherlands' employers' organization for companies in the metal, electronics, electrical engineering and plastic sectors. The FME negotiates working conditions with trade unions on behalf of its members, which, when agreed upon, are then applicable to all employees of Vlissingen. The current labor agreement is effective through December 31, 2025.
Approximately 39% of our U.S. based workforce is represented by USW through separately negotiated labor agreements for each facility. The labor agreement for Hawesville employees is effective through April 1, 2026. Upon announcement of the curtailment, Hawesville and the USW local union entered into effects bargaining. An agreement was reached on July 19, 2022, covering the curtailment period. Century Sebree's labor agreement with USW for its employees is effective through October 28, 2028.
Approximately 61% of Jamalco’s work force is represented by the Union of Technical, Administrative, and Supervisory Personnel ("UTASP") through separately negotiated labor agreements for hourly and salaried employee groups. Both contracts are effective through December 31, 2023. Jamalco is currently in the process of negotiating new contracts with both the salaried and hourly employee groups. Until new contracts are reached, employees will continue to operate under the current agreements.
Competition
The market for primary aluminum is global, and demand for aluminum varies widely from region to region. We compete with aluminum producers domestically and internationally, as well as with producers of alternative materials such as steel, copper, carbon fiber, composites, plastic and glass, each of which may be substituted for aluminum in certain applications. Our competitive position depends, in part, on the availability of electricity, alumina and our other key raw materials to our operations at competitive prices. We face global competition from companies who may have access to these key production costs at lower prices, and they may also receive various subsidies from local, state and federal governments. Many of our competitors are also larger than we are and have vertically integrated operations with superior cost positions. As a result, these companies may be better able to withstand reductions in price or other adverse industry or economic conditions.
Competitive Advantages
While we face significant competition, we also have several competitive advantages. We believe our key competitive advantages are:
Focus on Primary Aluminum Business. We operate principally in the production of primary aluminum. By concentrating our activities in primary aluminum production, we are able to focus our resources on optimizing the cost effectiveness of our existing operations, minimizing overhead costs and maintaining a market position where our products are ultimately targeted toward a broad range of end uses.
Strong Internal Growth Opportunities. Over the past several years, we have undertaken various expansion programs at all of our operating facilities and continue to pursue additional internal growth opportunities. In 2022, we completed a project to restart approximately 172,000 tonnes of production capacity at Mt. Holly (bringing its operations to 75% of Mt. Holly's maximum production capacity) and can restart another 58,000 tonnes of production capacity in the future provided we are able to obtain sufficient energy at competitive rates.
In 2024, Century completed construction of the Grundartangi Casthouse Project. The new value-added casthouse can produce up to 150,000 tonnes of billet and 120,000 tonnes of primary foundry alloys, in each case from existing Grundartangi production.
Since our purchase of the Vlissingen facility, we have completed a variety of expansion projects and efficiency programs in order to more than double its production capacity. Vlissingen supplies anodes primarily to our Grundartangi smelter, meeting 93% to 98% of Grundartangi’s carbon anodes requirements at current production levels. We continue to pursue additional internal growth opportunities to maximize efficiencies and improve overall performance.
Additionally, with our acquisition of a 55% interest in Jamalco, we secured a predictable, long-term supply of alumina, our most critical raw material, and achieved increased transparency and control of our supply chain. Our vertical integration with Jamalco allows us to integrate our aluminum smelting operations with this critical upstream supply of bauxite and alumina to create a more balanced and robust operational footprint, resulting in an organization that is better positioned to deliver strong performance through industry cycles.
7
Sustainability. Our Natur-Al™ aluminum produced at our Grundartangi facility has one of the lowest carbon footprints in the industry due to Grundartangi’s access to hydroelectric and geothermal power sources. Our Grundartangi facility (along with our corporate headquarters in Chicago, Illinois) have also been certified by the Aluminum Stewardship Initiative (ASI) for responsible production, sourcing and stewardship of aluminum. In addition to providing additional value to our customers, our low carbon footprint in Iceland mitigates our exposure to current or future carbon regulations. Century is committed to exploring additional opportunities to reduce our carbon footprint across our global operations, including by continuing to improve our operational efficiencies, investigating new and alternative power sources, and reprocessing and reusing scrap aluminum in our operations.
Duty Free Access to our Major Customer Markets. Our facilities benefit from international and national trade laws and regulations. For example, the European Union imposes import tariffs on primary aluminum from producers outside the European Economic Area (the "EEA"), which includes Iceland, and the U.S. currently imposes a 10% tariff on certain primary aluminum imports into the United States, which is expected to increase to 25% effective March 12, 2025. Our U.S. and Icelandic businesses currently access these respective markets duty-free which provides us with an advantage over our competitors who sell into these markets under these tariff regimes.
Close Proximity to our Major Customers in the Two Shortest Aluminum Markets in the World. The U.S. and the E.U. are the second and third largest aluminum consuming regions in the world, but do not produce enough aluminum domestically to satisfy their own demand. Our production locations within these markets provide us with a significant competitive advantage over our foreign competitors by providing our customers with short, reliable supply chains, better technical service and opportunities for value added collaboration. Our U.S. facilities benefit from the proximity to our U.S. customer base, allowing us to capture the Midwest premium and providing a competitive advantage in freight costs over our foreign competitors. In Iceland, our proximity to European markets provides a competitive advantage for Grundartangi, allowing us to capture the European Duty Paid Premium and other logistical benefits compared to our competitors outside the EEA.
Diverse Value Added Product and Secondary Market Portfolio. We have the ability across our operations to cast a variety of aluminum products, both in terms of shapes and alloys. These value-added primary aluminum products are sold at a premium to standard-grade aluminum. Each of our smelters have value-added casthouses that have the ability to produce large volumes of billet, slab and other value-added products.
Access to Market Power. Our Kentucky operations benefit from market-based power contracts that have historically provided electricity to these operations at competitive prices.
Experienced Management Team. Our management team includes executives and managers with significant experience in the aluminum industry, the broader metals and mining sector, the development of large and complex projects and the functional disciplines we require to manage and grow our business. In addition, the managers of our production facilities have substantial backgrounds and expertise in the technical and operational aspects of these plants.
For additional information, see Item 1A. Risk Factors . We may be unable to continue to compete successfully in the highly competitive markets in which we operate.
Government Regulations
Our facilities and operations are subject to various laws and regulations in the countries in which we operate, including, but not limited to, environmental laws and regulations. We have spent, and expect to continue to spend, significant amounts for compliance with those various laws and regulations, including environmental laws and regulations. In addition, some of our past manufacturing activities or those of our predecessors have resulted in environmental consequences that require remedial measures. Under certain environmental laws, which may impose liability regardless of fault, we may be liable for the costs of remediation of contaminated property, including our current and formerly owned or operated properties or adjacent areas, or for the amelioration of damage to natural resources. We believe, based on currently available information, that compliance with existing laws and regulations has not had a material adverse effect upon our capital expenditures, earnings and our competitive position. Furthermore, we believe, based on currently available information, that our current liabilities are not likely to have a material adverse effect on Century. However, we cannot predict the requirements of future laws and future requirements at current or formerly owned or operated properties or adjacent areas or the outcome of certain existing litigation to which we are a party. Such future requirements or events may result in unanticipated costs or liabilities that may have a material adverse effect on our financial condition, results of operations or liquidity. More information concerning our contingencies can be found in Note 17. Commitments and Contingencies to the consolidated financial statements included herein.
8
There is also increasing focus and scrutiny from both the United States government, foreign governments and other regulatory authorities on greenhouse gas ("GHG") emissions and potential impacts relating to climate change. We continuously review our own GHG and other emissions streams and seek to limit the impact of our operations on the communities in which we operate. Future laws, regulations, or policies that are enacted in response to concerns over GHG emissions and climate change, such as mandatory reporting and disclosure obligations, carbon tax, any "cap and trade" programs or similar regulatory measures, could significantly increase our operational and compliance burdens and costs. We continuously review and monitor climate change related proposed legislation for potential impacts on Century and our operations. For more information on the risk of climate change related legislation, laws and regulations, see Item 1A. Risk Factors.
Intellectual Property
We own or have rights to use a number of intellectual property rights relating to various aspects of our operations. We do not consider our business to be materially dependent on any of these intellectual property rights.
