Century Reports Third Quarter 2015 Financial Results

CHICAGO, IL -- 10/29/15 -- Century Aluminum Company (NASDAQ: CENX) reported a net loss of $56.1 million ($0.65 per common share) for the third quarter of 2015. Results were negatively impacted by a $5.3 million charge ($0.06 per common share) for lower of cost or market inventory adjustments, a $0.4 million charge ($0.01 per common share) related to the closure at Ravenswood, a $1.4 million charge ($0.02 per common share) related to the labor disruption at Hawesville, a $2.9 million charge ($0.04 per common share) related to the partial curtailment at Hawesville, and a $1.2 million charge ($0.01 per common share) related to severance primarily associated with cost reductions. Results were positively impacted by an $0.8 million purchase accounting gain ($0.01 per common share) related to Mt. Holly. After consideration of these items, the company reported an adjusted net loss of $45.7 million and adjusted loss per share of $0.48.

For the third quarter of 2014, Century reported net income of $50.4 million or $0.52 per common share.

Sales for the third quarter of 2015 were $454.5 million compared with $500.6 million for the third quarter of 2014. Shipments of primary aluminum for the third quarter of 2015 were 231,040 tonnes compared with 218,214 tonnes shipped in the third quarter of 2014.

Net cash used by operating activities in the third quarter of 2015 was $31.9 million compared to net cash provided of $89.1 million in the third quarter of 2014. Cash and cash equivalents decreased $44.4 million during the third quarter of 2015 compared to an increase in cash and cash equivalents of $72.0 million in the third quarter of 2014.

Our total liquidity position at the end of the third quarter of 2015 was $223 million, which is composed of $123 million in cash and $100 million of revolver availability.

For the first nine months of 2015, Century reported net loss of $16.2 million ($0.19 per common share). Results include a $31.2 million charge related to the permanent closure of Ravenswood and a $31.0 million charge for lower of cost or market inventory adjustments. Results were also negatively impacted by $13.1 million in costs related to the labor disruption at Hawesville, $2.9 million due to partial curtailment at Hawesville, $1.2 million related to severance, $1.6 million for signing bonuses related to a new labor agreement in Iceland and $1.0 million related to the separation of a former senior executive. Lastly, results include an $18.3 million unrealized gain on the fair value of contingent consideration related to the acquisition of the remaining 50.3% interest of Mt. Holly.

For the first nine months of 2014, Century reported net income of $50.6 million or $0.52 per common share. Cost of sales for the first nine months included a benefit of $5.5 million related to power contract amortization and $1.2 million for lower inventory costs. Results were negatively impacted by $3.6 million for a legal settlement.

Sales for the first nine months of 2015 were $1,565.9 million compared with $1,379.8 million for the first nine months of 2014. Shipments of primary aluminum for the first nine months of 2015 were 710,248 tonnes compared with 641,043 tonnes shipped for the first nine months of 2014.

Net cash provided by operating activities in the first nine months of 2015 was $32.5 million compared to $97.7 million in the first nine months of 2014. Cash and cash equivalents decreased $40.3 million during the first nine months of 2015 compared to an increase in cash and cash equivalents of $49.3 million in the first nine months of 2014. During the first nine months of 2015, Century acquired 2.4 million shares of common stock for a total cost of $36.4 million and paid $38.2 million related to the Mt. Holly acquisition, primarily for pension funding obligations per the terms of the acquisition agreement.

"Sentiment toward a broad range of commodities, brought about by a number of factors, has deteriorated markedly during the last few months," commented Michael Bless, President and CEO. "The issues in the primary aluminum sector are straightforward. Demand in most developed markets remains reasonably good. There is a supply deficit in the world excluding China and, given a lack of new capacity projects at any stage of gestation, this western world supply deficit is likely to persist for the foreseeable future. These otherwise favorable conditions have been severely neutralized by the global supply glut caused by the government of China's continued unfair subsidization of additional capacity expansion in China and further assistance to maintain existing capacity irrespective of market forces. Chinese metal is often further transported and processed via blatantly uneconomic methods that would not be possible but for the large subsidies these Chinese producers are receiving from their government. This behavior has caused a meaningful deterioration in the operation of orderly global markets.

"We are working actively with the industry and the U.S. government to address this situation, which must be rectified,” Mr. Bless continued. “Our collective goal is no more than fair trade and transparent markets and equal conditions for all industry participants. At Century, we are taking the necessary actions to structure all of our operations to remain viable assuming a protracted period of these conditions. Most recently we have taken the decision to operate Hawesville at forty percent of its rated capacity; the resultant cost structure and product mix should enable the plant to operate at a break even level, even in the current price environment. We are approaching our other U.S. operations in a similar manner. This overall cost structure, coupled with significant liquidity and low financial leverage (with no funded debt maturities for several years) will enable Century to remain strong during what could be a protracted difficult environment.

"We recently took the regrettable and very difficult decision to issue WARN notices to the employees at our Mt. Holly plant in South Carolina. Mt. Holly is the safest, most modern and most efficient smelter in the U.S., with a truly extraordinary group of employees. It has, over time, had the highest power cost of any U.S. smelter and this situation persists today, by a good margin. As we have stated, we have reached a market-based agreement with a high quality supplier to generate and deliver Mt. Holly's full power load to the local utility's border. Regrettably, we have been unable to reach agreement with the local utility to deliver the power to the plant despite our offer to pay the full transmission tariff rate. This failure of the operation of a free market is unacceptable and we will fight during the next two months for the future of this excellent plant and the people who depend on it."

Non-GAAP Financial Measures

Adjusted net income and adjusted earnings per share are non-GAAP financial measures that management believes provide additional meaningful information regarding Century’s financial performance as these measures generally exclude the effects of items that are considered non-recurring, are difficult to predict or to measure in advance or that are not directly related to the Company’s ongoing operations. The table below, under the heading “Reconciliation of Non-GAAP Financial Measures,” provides a reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP. In addition, because not all companies use identical calculations, adjusted net income and adjusted earnings per share included in this press release may not be comparable to similarly titled measures of other companies. Investors are encouraged to review the reconciliation in conjunction with the presentation of these non-GAAP financial measures.
