Company Description

Century Aluminum Company (NASDAQ: CENX) is an integrated producer of bauxite, alumina and primary aluminum products. According to company disclosures, Century Aluminum is the largest producer of primary aluminum in the United States and operates across multiple stages of the aluminum value chain, from raw materials to finished metal. The company’s corporate headquarters is located in Chicago, Illinois, and its common stock is listed on the Nasdaq Global Select Market.

Century Aluminum owns and operates primary aluminum smelting facilities in the United States and Iceland. It is also the majority owner and managing partner of the Jamalco alumina refinery in Clarendon, Jamaica. In addition, Century Aluminum operates production facilities in the Netherlands and has described itself as an integrated producer of bauxite, alumina and primary aluminum products, reflecting its involvement in mining, refining and smelting activities.

The company’s operations include primary aluminum smelting facilities that produce aluminum metal, as well as alumina refining capacity through its Jamalco joint venture. Century Aluminum has stated that it operates production facilities in Iceland, the Netherlands and Jamaica, alongside its U.S. smelters. The company has also indicated that it owns a carbon anode production facility in the Netherlands and that it produces high purity aluminum, standard-grade aluminum sow and tee bars, and value-added billet and foundry products.

Century Aluminum’s business is closely tied to global aluminum markets, regional aluminum premiums and the cost and availability of key inputs such as alumina and power. The company has highlighted the importance of power arrangements for its smelters, including a power agreement for its Mt. Holly facility in South Carolina. Century Aluminum has announced plans and agreements related to restarting idled capacity at Mt. Holly, with the goal of returning that smelter to full production, and has described this restart as a step in increasing U.S. primary aluminum production.

In its public communications, Century Aluminum has emphasized the role of trade measures such as Section 232 tariffs on primary aluminum. The company has linked the restart of idled capacity at its Mt. Holly smelter to changes in Section 232 aluminum tariffs, describing these tariffs as a factor supporting domestic primary aluminum production. Century Aluminum has also noted that it works with power suppliers such as South Carolina Public Service Authority (Santee Cooper) to secure power for its operations.

Century Aluminum’s integrated structure means that its financial performance is influenced by aluminum prices, regional premiums, raw material costs, power prices and operational reliability. The company reports net sales, aluminum shipments, net income or loss, and non-GAAP measures such as adjusted net income and adjusted EBITDA in its quarterly financial results. It has explained that non-GAAP measures are used by management to evaluate performance and to facilitate comparisons across periods by excluding items management does not consider indicative of ongoing operating performance.

Century Aluminum’s operations can be affected by events at its facilities. For example, the company has reported an electrical equipment failure affecting one potline at its Grundartangi aluminum smelter in Iceland, which temporarily reduced production at that facility. The company indicated that the other potline remained in full production and that it expected losses from the event to be covered under its property and business interruption insurance policies. Similarly, Century Aluminum’s Jamalco joint venture has reported temporary curtailment and subsequent restart procedures following a hurricane, noting that there were no injuries or material damage to the refinery, mines or port operations.

Century Aluminum also manages its capital structure and liquidity through debt offerings and credit facilities. The company has completed a private offering of senior secured notes due 2032 and has used the proceeds to refinance existing senior secured notes, repay borrowings under its credit facilities and pay related fees and expenses. It has also amended its loan and security agreement to extend the maturity of its credit facility and adjust certain terms. These financing activities are described in detail in the company’s Form 8-K filings.

Investors and analysts following Century Aluminum can review its quarterly results, liquidity position, debt structure and operational updates through the company’s press releases and SEC filings. Century Aluminum provides information on its net sales to related parties and other customers, cost of goods sold, gross profit, operating income, interest expense, derivative contract results and other items in its consolidated financial statements. The company also discusses factors that affect its results, including aluminum prices, regional premiums, derivative instruments, raw material costs, power prices, equipment issues and labor costs associated with projects such as the Mt. Holly restart.

Century Aluminum includes extensive cautionary statements about forward-looking information in its public disclosures. These statements explain that expectations about aluminum markets, tariffs, power prices, raw material costs, operations, financing, tax matters, insurance recoveries, potential projects and other topics are subject to risks and uncertainties. The company refers readers to the risk factors and cautionary language in its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other SEC filings for a fuller discussion of these risks.

Operations and geographic footprint

Century Aluminum has described itself as an integrated producer of bauxite, alumina and primary aluminum products, with operations in the United States, Iceland, the Netherlands and Jamaica. The company owns and operates primary aluminum smelting facilities in the United States and Iceland and is the majority owner and managing partner of the Jamalco alumina refinery in Jamaica. It has also stated that it operates production facilities in the Netherlands and owns a carbon anode production facility there.

In the United States, Century Aluminum’s operations include the Mt. Holly smelter in South Carolina. The company has announced plans to restart idled capacity at Mt. Holly, supported by an extension of its power agreement with Santee Cooper through 2031. Century Aluminum has described this restart as involving investment to increase production and create new jobs, with the goal of bringing the plant to full production.

In Iceland, Century Aluminum operates the Grundartangi aluminum smelter through its wholly owned subsidiary Norðurál Grundartangi ehf. The company has reported that an electrical equipment failure temporarily stopped production on one of the smelter’s two potlines, reducing production by approximately two-thirds while the other potline remained in full production. Century Aluminum has stated that it is assessing the impact and working on a timeline for obtaining replacement equipment and restoring full production.

Through its Jamalco joint venture in Clarendon, Jamaica, Century Aluminum participates in alumina refining and related mining and port operations. Following Hurricane Melissa, Jamalco temporarily curtailed production as part of its hurricane preparedness plan and later began restart procedures. Century Aluminum has reported that there were no injuries or material damage at Jamalco’s refinery, mines or port operations and that production is expected to return to normal levels gradually.

Products and customers

Century Aluminum produces primary aluminum in various forms. Based on available information, the company produces high purity aluminum, standard-grade aluminum sow and tee bars, and value-added billet and foundry products. These products serve customers that purchase primary aluminum metal, including related parties and other customers, as reflected in the company’s net sales breakdown between related party sales and other customer sales in its financial statements.

The company has indicated that a significant portion of its net sales is to related parties and that it purchases a substantial amount of alumina from related parties. Earlier descriptions note that Century Aluminum has generated a majority of its revenue from a major customer that agreed to purchase nearly all of its North American production and that it purchases nearly all of its alumina from that same related party. These relationships are reflected in the company’s reporting of net sales to related parties and due from affiliates in its balance sheet.

Financial reporting and performance measures

Century Aluminum reports its financial results on a quarterly basis, including net sales, aluminum shipments, net income or loss attributable to Century stockholders, and earnings per share. The company also reports adjusted net income, adjusted earnings per share and adjusted EBITDA, which it identifies as non-GAAP financial measures. Century Aluminum explains that management uses these non-GAAP measures to evaluate financial performance and that they are intended to facilitate comparisons with prior periods by excluding items that management does not believe are indicative of ongoing operating performance and cash generation.

In its explanations of non-GAAP measures, Century Aluminum notes that adjusted net income, adjusted earnings per share and adjusted EBITDA should be viewed in addition to, and not as an alternative for, reported results prepared in accordance with U.S. GAAP. The company also notes that not all companies use identical calculations, so these measures may not be directly comparable to similarly titled measures of other companies. Reconciliations of non-GAAP measures to the most directly comparable GAAP measures are provided in tables accompanying the company’s earnings press releases.

Century Aluminum’s results are affected by factors such as aluminum prices, regional premiums (including the Midwest premium), derivative contract results, raw material costs, power costs, volume and sales mix, and exceptional items. The company has discussed the impact of realized regional premiums, derivative losses, equipment failures, inventory adjustments, share-based compensation, and other items on its net income or loss and adjusted results.

Capital structure, liquidity and financing

Century Aluminum provides information about its liquidity position, including cash and cash equivalents and borrowing availability under its credit facilities. The company has reported liquidity composed of cash and cash equivalents and combined borrowing availability and has described changes in these amounts over time. It has also disclosed details of its debt structure, including senior secured notes and credit facilities.

In a Form 8-K filing, Century Aluminum reported completing an offering of 6.875% Senior Secured Notes due 2032. The notes were issued under an indenture and are guaranteed by certain domestic restricted subsidiaries. The obligations under the notes are secured, subject to exceptions and permitted liens, by liens on substantially all of the company’s and guarantors’ assets other than specified collateral that secures indebtedness under the company’s credit agreement and certain other excluded property. The company has explained that the notes rank equally with existing and future senior indebtedness, are effectively senior to unsecured indebtedness to the extent of the value of the collateral, and are senior to existing and future subordinated indebtedness, while being effectively junior to obligations under the credit agreement with respect to certain collateral.

Century Aluminum has also amended its loan and security agreement to extend the maturity of its credit facility, revise the amount of swingline loans, adjust concentration limits for certain customers, and modify other terms. The company has indicated that proceeds from the offering of the senior secured notes will be used to redeem its 7.50% senior secured notes due 2028, repay borrowings under its credit facilities and pay related fees and expenses. These actions are part of the company’s approach to managing its capital structure and debt maturities.

Risk disclosures and forward-looking statements

Century Aluminum includes detailed cautionary statements regarding forward-looking information in its press releases and SEC filings. The company notes that forward-looking statements are based on current expectations and assumptions and are subject to risks and uncertainties that could cause actual results to differ materially. It lists examples of topics covered by forward-looking statements, including assessments of global and local financial and economic conditions, aluminum markets and prices, raw material prices and availability, power prices and availability, the impact of geopolitical events and trade actions, future financial and operating performance, cost management, operational plans such as curtailments and restarts, power arrangements, tax matters, financing, insurance recoveries, legal and environmental liabilities, labor relations, information technology risks, potential mergers and acquisitions, and future business objectives and competitive position.

The company directs readers to the risk factors and cautionary language in its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and other SEC filings for more information about these risks.
