OJSC MMC Norilsk Nickel announced that its direct subsidiary Norilsk Nickel Investments Limited has completed its previously announced offer to purchase issued and outstanding shares of common stock including American Depositary Shares, representing Common Shares of OJSC MMC Norilsk Nickel.

NN Investments has been advised by Citigroup Global Markets Limited, acting as the dealer manager for the offer to purchase, that as of October 28th 2011 at 4:00 PM Moscow time, a total of 119,780,706 common shares, including common shares represented by ADSs, had been validly tendered pursuant to the offer to purchase.

As contemplated in the offer to purchase, the pro ration factor calculated according to the offer memorandum dated September 27th 2011 is 0.1094789399. NN Investments will therefore purchase from each security holder of OJSC MMC Norilsk Nickel who has properly tendered its common shares or ADSs prior to the expiration time the number of ADSs or Common Shares calculated pursuant to the formula set forth in the offer memorandum by multiplying the number of securities properly tendered by such security holder by the pro ration factor indicated above with downward adjustment to the next closest whole number to avoid the purchase of fractional securities. NN Investments will purchase without pro ration all properly tendered odd lots of common shares and ADSs in accordance with the terms and conditions set forth in the offer memorandum.

Security holders, who have tendered their common shares or their duly authorized representatives or Russian licensed securities trustees must, as set forth in the Common Shares Letter of Transmittal, not later than ten Russian business days from the fourth Russian business day following the Expiration Time, i.e. during the period commencing on November 7, 2011 and ending on November 18, 2011, inclusive, appear at the office of Closed Joint Stock Company Computer share Registrar to which such security holder, its duly authorized representative or Russian licensed securities trustee originally submitted the Common Shares Letter of Transmittal in order to sign all required documents.
