The Russian Federal Service for Financial Markets made a decision to cancel the individual number (code) 039D of state registration number 1-01-55038-Å-039D from December 2nd, 2010, which had been assigned to the additional issue of ordinary shares of JSC RusHydro (ticker symbol: RTS, MICEX, LSE: HYDR; OTCQX: RSHYY).

A combination of the Company's additional share issue with the main share issue on MICEX Stock Exchange's trading system will occur shortly. Following this procedure, all of the Company's ordinary shares will be traded on the «À1» quotation list of the MICEX stock exchange.
