NEW YORK, NY--(Marketwire - April 15, 2008) - Abraham, Fruchter & Twersky, LLP filed a class action lawsuit in the United States District Court for the Southern District of New York on behalf of purchasers of the common stock of The Blackstone Group L.P. ("Blackstone" or the "Company") (NYSE: BX) pursuant and/or traceable to the Company's initial public offering on or about June 25, 2007 (the "IPO" or the "Offering").

The complaint charges Blackstone and certain of its officers and directors with violations of the Securities Act of 1933. Blackstone, through its subsidiaries, provides alternative asset management and financial advisory services worldwide.

According to the complaint, on or about June 21, 2007, Blackstone filed with the SEC a Form S-1/A Registration Statement (the "Registration Statement"), for the IPO. On or about June 25, 2007, the Prospectus with respect to the IPO, which forms part of the Registration Statement, became effective and, including the exercise of the over-allotment, more than 133 million shares of Blackstone's common stock were sold to the public at $31 per share, thereby raising more than $4 billion.

The complaint alleges that the Registration Statement failed to disclose that certain of the Company's portfolio companies were not performing well and were of declining value. As a result, Blackstone's equity investment was impaired and the Company would not generate anticipated performance fees on those investments or would have fees "clawed-back" by limited partners in its funds.

On March 10, 2008, Blackstone issued a press release announcing its financial results for the full year of 2007 and the fourth quarter of 2007, the periods ending December 31, 2007. Among other disclosures, Blackstone announced that it was writing down its investment in Financial Guaranty Insurance Company by $122 million. As of April 15, 2008, Blackstone common stock traded in a range of $17.00-$17.50 per share, approximately 45% below the IPO price of $31.00 per share.

Plaintiff seeks to recover damages of all those who purchased the common stock of Blackstone pursuant and/or traceable to the Company's IPO on or about June 25, 2007. The Plaintiff is represented by Abraham, Fruchter & Twersky, LLP which has extensive experience in securities class action cases, having been ranked among the leading class action law firms in terms of recoveries achieved by a survey of class action law firms conducted by Institutional Shareholder Services.
