The new CUSIP number for the company's common stock will be 909214306. The reverse stock split will automatically combine every ten shares of Unisys common stock into one share of common stock. As of today, there were approximately 423 million shares of Unisys common stock outstanding. After giving effect to the reverse stock split, there will be approximately 42.3 million shares outstanding. No fractional shares will be issued in connection with the reverse stock split. Instead, the company's transfer agent will aggregate all of the fractional shares that otherwise would have been issued as a result of the reverse stock split and sell those shares. Stockholders who would otherwise hold a fractional share of the company's common stock will receive a cash payment in lieu of such fractional share equal to their pro rata share of the proceeds received by the transfer agent. Instructions and a letter of transmittal relating to the reverse stock split will be mailed to holders of certificates representing pre-split common stock.
