New York — Blackstone announced today that the initial public offering of 133,333,334 common units representing limited partner interests in The Blackstone Group L.P. has been priced at $31.00 per common unit. The common units are expected to begin trading tomorrow, June 22, 2007, on the New York Stock Exchange under the symbol “BX.” The Blackstone Group has granted the underwriters a 30-day option to purchase up to 20,000,000 additional common units at the public offering price less underwriting discounts.

Blackstone intends to use a portion of the proceeds from the initial public offering and the concurrent sale of $3 billion of non-voting common units to an investment vehicle established by the People’s Republic of China with respect to its foreign exchange reserve to purchase interests in its business from its existing owners, to repay short-term borrowings, to provide capital to invest in its existing businesses and to expand into complementary new businesses and for other general corporate purposes.
