Century Reports Third Quarter 2016 Financial Results

CHICAGO, IL -- 10/27/16 -- Century Aluminum Company (NASDAQ: CENX) reported a net loss of $58.3 million ($0.67 per share) for the third quarter of 2016. Results were negatively impacted by a $26.8 million ($0.31 per share) charge related to the closure of the Ravenswood facility, including settlement costs associated with the retiree medical class action lawsuit, and a $2.4 million ($0.03 per share) lower of cost or market inventory adjustment. The third quarter adjusted net loss was $29.1 million ($0.31 per share).

For the third quarter of 2015, Century reported a net loss of $56.1 million ($0.65 per share). Results were negatively impacted by a $5.3 million charge ($0.06 per share) for lower of cost or market inventory adjustments, a $0.4 million charge ($0.01 per share) related to the permanent closure of the Ravenswood facility, a $1.4 million charge ($0.02 per share) related to the labor disruption at Hawesville, a $2.9 million charge ($0.04 per share) related to the partial curtailment of our Hawesville facility, and a $1.2 million charge ($0.01 per share) related to severance primarily associated with cost reductions. Results were positively impacted by a $0.8 million purchase accounting gain ($0.01 per share) related to Mt. Holly.

Sales for the third quarter of 2016 were $333.7 million compared with $454.5 million for the third quarter of 2015. Shipments of primary aluminum for the third quarter of 2016 were 182,429 tonnes compared with 231,040 tonnes shipped in the third quarter of 2015. The decrease in sales and shipment volume was primarily due to curtailment actions taken in the second half of 2015.

Net cash used by operating activities in the third quarter of 2016 was $8.0 million. Our cash position at quarter end was $117.6 million and we had $90.4 million of revolver availability.

For the first nine months of 2016, Century reported a net loss of $84.0 million ($0.96 per share). Results included the negative impact of a $26.8 million ($0.31 per share) charge related to the closure of the Ravenswood facility, including settlement costs associated with the retiree medical class action lawsuit, and a $1.5 million ($0.02 per share) lower of cost or market inventory adjustment.

For the first nine months of 2015, Century reported a net loss of $16.2 million ($0.19 per share). Results included 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 also included $13.1 million in costs related to the labor disruption at Hawesville, $2.9 million due to the partial curtailment of our Hawesville facility, $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 included an $18.3 million unrealized gain on the fair value of contingent consideration related to the Mt. Holly acquisition.

Sales for the first nine months of 2016 were $979.3 million compared with $1,565.9 million for the first nine months of 2015. Shipments of primary aluminum for the first nine months of 2016 were 550,615 tonnes compared with 710,248 tonnes shipped for the first nine months of 2015. The decrease in sales and shipment volume was primarily due to curtailment actions taken in the second half of 2015.

"A cross current of factors is influencing our markets," commented Michael Bless, President and Chief Executive Officer. "The commodity price has firmed and regional delivery premiums are somewhat stronger. Demand remains generally good and supply, excluding in China, continues to be constrained. On the other hand, value-added product premiums, especially in the U.S., are under pressure due to the significant and growing level of imports caused by the excess production in China. Power prices rose during the summer due to the abnormally warm weather and certain markets, like natural gas, remain elevated due to expectations for a cold winter."

"Third quarter financial performance was negatively influenced by elevated power prices in the U.S. Midwest, a result of the historically hot summer weather; delivered prices have now generally reverted to pre-summer levels," Mr. Bless continued. "In addition, rising alumina prices pressured quarterly results. We believe this trend is largely a reaction to the startup of new capacity in China, and we expect it to temper over the coming months. Internally, our operations are performing well and our cost structure, flexibility and product configuration continue to provide protection against weaker pricing environments as well as exposure when the market firms."

"Overcapacity and overproduction continue to subsist in great quantities in China, negatively impacting rational producers and markets in the rest of the world," concluded Mr. Bless. "We firmly believe all major market participants are fully aware of the subsidies, illegal under WTO rules, that allow this overcapacity and overproduction to continue to exist and the distortion to fair

trade that this behavior is causing. We applaud the growing list of members of Congress, including Senators Brown, Casey, Gillibrand, McConnell, Merkley, Portman, Schumer, Stabenow and Wyden, who, over the last few weeks, have called on the administration to take immediate action to enforce global trade law and protect this sector and those that depend on it. These constituencies include employees and their families in countless communities as well as U.S. national defense interests."

Non-GAAP Financial Measures

Adjusted net income (loss) and adjusted earnings (loss) per share are non-GAAP financial measures that management uses to evaluate Century's financial performance. These non-GAAP financial measures facilitate comparisons of this period’s results with prior periods on a consistent basis by excluding items that management does not believe are indicative of Century’s ongoing operating performance and ability to generate cash. Management believes these non-GAAP financial measures enhance an overall understanding of Century’s performance and our investors’ ability to review Century’s business from the same perspective as management. 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, Century's reported results prepared in accordance with GAAP. In addition, because not all companies use identical calculations, adjusted net income (loss) and adjusted earnings (loss) 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.
