New York, New York, June 21, 2007—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.
