Mechel OAO’s Chief Executive Officer Yevgeny Mikhel commented on the company’s 1H 2011 operational results:

“In the first six months of 2011 we managed to exceed on most major points the operational results for the same period last year, thus consolidating our earlier success in increasing production and sales in our principal markets. Despite a minor decrease in coal production, which was due to a temporary halt of Yakutugol’s Nerungrinskaya washing plant, the Group managed to profit by growing demand and increase sales volumes of coking coal concentrate by 28% compared to the first half of 2010. We achieved particularly impressive growth in PCI sales volumes, which rose by 242% in the first half of 2011 compared to the same period last year, with the company demonstrating confident growth of sales volumes of other mining products as well.

“Due to the planned repairs done at Chelyabinsk Metallurgical Plant’s blast furnace, Mechel’s steel segment temporarily decreased pig iron production, but that did not reflect on the sales volumes of the Group’s metal products. The international steel sales network Mechel Service Global’s sales volumes in the first half of 2011 can well be called record-breaking. Despite complicated price conditions in 2011’s first quarter, the company’s well-developed storage network enabled us to retain positive dynamics in sales volumes both in Russia and abroad. Mechel Service Global managed to promptly prepare its infrastructure to meet pent-up demand during the seasonal sales growth. In the first half of 2011 our steel division demonstrated a confident growth in sales volumes of long products, which increased by 11% compared to the same period last year. We also had higher sales volumes of downstream products — hardware sales volumes went up by 20% and stampings by 33% compared to the same period last year. Due to active expansion on international markets, Mechel Service Global increased sales volumes of steel flats by 61% compared to the first half of 2010. As a whole, sales volumes of Mechel’s steel products are growing due to increased sales of Mechel enterprises’ own products, as the share of third-party products declined from 11% to 6% since the beginning of this year.

“Despite a temporary decline in chrome production, which was due to Voskhod Mining Plant’s mining through an ore body with lower level of chrome in the ore, the ferroalloys segment also demonstrated good sales volumes in the first half of 2011. Sales volumes of nickel and ferrosilicon continued to grow compared to the same period last year.

“Compared with the first half of 2010, Mechel’s power division increased heat power generation by 2% and decreased electric power generation by 10%. The decrease is due to repairs conducted by the electric grid companies that distribute electricity generated by Southern Kuzbass Power Plant. Therefore, the plant briefly halted energy supplies to the wholesale market.”
