KBR Expects to Net $508 Million from IPO

KBR, the engineering, construction and services subsidiary of Halliburton, said late Thursday that the underwriters of its initial public offering have exercised in full their over-allotment option to purchase an additional 4,176,000 shares of common stock in connection with KBR's previously announced initial public offering. The exercise of this option will bring the total number of shares of common stock to be sold in the offering to 32,016,000, at a price of $17.00 per share. The shares have been approved to trade on the New York Stock Exchange under the symbol "KBR."

KBR expects to receive approximately $508 million of proceeds from the offering, net of underwriting fees and estimated expenses. KBR intends to use the proceeds to repay indebtedness owed to subsidiaries of Halliburton and for general business purposes.

The offering is expected to close on November 21, 2006, subject to customary closing conditions. After the IPO, Halliburton will remain the majority stockholder of KBR, with approximately 81 percent of KBR's outstanding stock.

The lead underwriters for the offering are Credit Suisse Securities (USA) LLC, Goldman, Sachs & Co., and UBS Securities LLC.
