MECHEL ANNOUNCES SIGNING COOPERATION AGREEMENT ON SUPPLIES OF ELGA COMPLEX’S
COAL PRODUCTS WITH RAO ENERGY SYSTEMS OF EAST

Moscow, Russia — September 10, 2012 – Mechel OAO (NYSE: MTL), one of the leading
Russian mining and metals companies, announces the signing of a cooperation
agreement for supplying OJSC “RAO Energy Systems of East” with coal from Elga
Coal Complex.
As part of an official meeting during the Business Summit of the Asia Pacific
Economic Cooperation (APEC), Mechel Mining OAO, which consolidates Mechel
Group’s mining assets, and OJSC “RAO Energy Systems of East” signed an agreement
for cooperation for supplies of the Elga deposit’s coal. The agreement was
signed by Mechel Mining OAO’s Chief Executive Officer, Igor Zyuzin, and OJSC
“RAO Energy Systems of East”’s Chief Executive Officer, Sergey Tolstoguzov.
The agreement sets forth the key principles of the two sides’ long-term
cooperation regarding the use of coal from the Elga deposit. Once probes of
Elga’s coals are delivered to OJSC “RAO Energy Systems of East” subsidiary JSC
“DTE” and in case test burning yields positive results, Mechel Mining may
gradually increase supplies of the Elga deposit’s coals up to a total of 60
million tonnes over 15 years.
“Mechel has longstanding partnership ties with DTE. For many years, DTE’s
Neryungri and Khabarovsk power stations were supplied with steam coal from
Neryungri Open Pit, which is part of Yakutugol. Signing the cooperation
agreement for supplies of Elga’s coal with RAO Energy Systems of East is a new
stage in the business ties between our companies. What is particularly
important, this agreement will ensure guaranteed sales of products from Elga
Coal Complex, which is a priority development project for our company, on the
Russian coal market,” Mechel Mining OAO’s Chief Executive Officer Igor Zyuzin
noted.
