Century Aluminum Reports Third Quarter 2011 Results

MONTEREY, CA. October 25, 2011 -- Century Aluminum Company (NASDAQ:CENX) reported a net loss of $6.6 million ($0.07 per basic and diluted share) for the third quarter of 2011.  Financial results were positively impacted by a mark-to-market gain on forward contracts of $4.2 million related primarily to aluminum put options. Cost of sales for the quarter included a $13.5 million charge for lower of cost or market inventory adjustments.

In the third quarter of 2010, the company reported a net loss of $16.8 million ($0.18 per basic and diluted share).  Reported results were negatively impacted by a mark-to-market loss on forward contracts of $12.1 million related primarily to aluminum put options and positively impacted by a $1.4 million tax benefit related to the release of tax reserves no longer required. Cost of sales for the quarter included a $15.8 million charge for the portion of power costs at Hawesville payable by the previous power supplier per the terms of the power agreements and a $7.3 million benefit for lower of cost or market inventory adjustments.

Sales in the third quarter of 2011 were $345.6 million, compared with $279.2 million in the third quarter of 2010.  Shipments of primary aluminum for the quarter totaled 150,832 tonnes compared with 147,216 tonnes in the year-ago quarter.

For the first nine months of 2011, the company reported net income of $42.4 million ($0.42 per basic and diluted share).  These results were negatively impacted by a $7.7 million charge related to the contractual impact of the recent changes in the Company's Board of Directors and the executive management team; a charge of $2.9 million related to an insurance receivable; a loss on forward contracts of $2.3 million, related primarily to the marking to market of aluminum put options; and a charge of $0.8 million related to the early retirement of debt. Changes to the Century of West Virginia retiree medical benefits program increased nine month results by $18.3 million with an associated discrete tax benefit of $4.2 million. Cost of sales included an $8.6 million charge related to the restart of a curtailed potline at the Hawesville, KY smelter and a $13.5 million charge for lower of cost or market inventory adjustments. For the first nine months of 2010, the company reported a net loss of $5.3 million ($0.06 per basic and diluted share).  Prior year results were negatively impacted by a mark-to-market loss on forward contracts of $4.8 million related primarily to aluminum put options. Cost of sales for the 2010 nine month period included a $47.3 million charge for the portion of power costs at Hawesville payable by the previous power supplier per the terms of the power agreements and a $0.3 million benefit for lower of cost or market inventory adjustments.

Sales in the first nine months of 2011 were $1,038.3 million compared with $852.4 million in the same period of 2010.  Shipments of primary aluminum for the first nine months of 2011 were 446,493 tonnes compared with 436,472 tonnes for the comparable 2010 period.

“The events of the last two months, and their impact on our industry, remind us all of the volatility of the world in which we live,” commented Logan W. Kruger, President and Chief Executive Officer.  “Clearly, the risk remains that the significant problems facing sovereigns and financial institutions could more substantially influence economic conditions in both developed and emerging economies.  That said, we continue to see reasonably good business conditions in our markets.  The relative difficulty in obtaining supplies of near-term metal, driven by a number of factors, continues to support attractive premiums in most regions.  While the commodity price has fallen, it is supported by the rising cost of production being experienced by all industry participants.

 “During the quarter, we continued on a steady pace to return the Hawesville smelter to stable operations,” added Mr. Kruger.  “We expect these efforts will produce improvement in production and shipments in the fourth quarter.  Grundartangi’s performance has been excellent, with record production and strong safety results and operating efficiencies.  All of our businesses continue to manage through the increases we are seeing in the costs of electric power and raw materials, specifically carbon.  Lastly, discussions continued in several key areas of the Helguvik project, and we are awaiting a decision from the arbitration panel regarding our contractual dispute with one of the power suppliers.”

Century Aluminum Company owns primary aluminum capacity in the United States and Iceland. Century's corporate offices are located in Monterey, California.
