ALERIS TO SELL ITS EXTRUSIONS BUSINESS TO SANKYO TATEYAMA, INC.

CLEVELAND, OH – December 18, 2014 – Aleris announced today that it has signed a definitive agreement to sell its aluminum extrusions business to Sankyo Tateyama, Inc., a Japanese building products and extrusions manufacturer. The sale includes four production facilities in Europe and one in China. The facilities specialize in the production of medium and hard alloy extrusions, serving the rail, automotive and aerospace industries. Sankyo Tateyama has agreed to pay a purchase price of €35.5 million for the business and assume approximately €46 million of pension liabilities. The transaction is expected to close in the first quarter of 2015.

“The sale of our extrusions business represents the last step in our strategy to position Aleris to become a pure global rolled products business focused on serving a diverse set of industries including automotive, aerospace, and building and construction,” Steve Demetriou, Aleris chairman and CEO said. “We will use the proceeds from the sale of extrusions to strengthen our balance sheet and enhance our liquidity as we continue to reinvest in our rolled products capabilities.”

The announcement of the extrusions transaction follows the company’s announcement in October that it plans to sell its recycling and specification alloys businesses to Signature Group Holdings. Upon the completion of both transactions, Aleris will become a singularly focused global rolled products company with manufacturing sites in North America, Europe, and China. In 2013, the extrusions business accounted for $355 million of the company’s $4 billion in total revenue.

“The extrusions business is a solid, well-run business that serves a number of premier customers, but it represents a relatively small part of the overall Aleris portfolio,” Demetriou added. “Sankyo Tateyama views these sites as very complementary to their existing extrusions business, bringing advanced production technology and strategic geographic locations that will enable Sankyo Tateyama to grow.”

Aleris has made a number of investments in its rolled products business over the past several years, including the construction of a world-class aerospace plate mill in Zhenjiang, China, a new

automotive facility in Duffel, Belgium, and this year’s acquisition of Nichols Aluminum in the U.S. In October, the company also broke ground on a $350 million investment in its Lewisport, Kentucky facility to serve the automotive industry.

Moelis & Company LLC acted as exclusive financial advisor to Aleris on this transaction. Fried Frank acted as legal advisor.
