AlliedBarton fetches $750 million

Last week, Blackstone Group agreed to buy AlliedBarton Security Services from MacAndrews & Forbes Holdings Inc.

Today, we know how much the New York private-equity firm is paying for the King of Prussia-based security guard firm: $750 million.

In a Securities and Exchange Commission filing, Blackstone said that cash amount includes a $50 million maximum potential earnout payment. That money is paid only if AlliedBarton achieves certain levels of earnings before income taxes, depreciation and amortization for its fiscal year ended Dec. 31, 2009.

Important to note: The deal could be terminated if it doesn't close on or before Oct. 10. Blackstone would have to pay a fee under certain circumstances, but the amount of the breakup fee wasn't disclosed in the SEC filing.

MacAndrews & Forbes, which is the conglomerate controlled by billionaire Ronald O. Perelman, paid $263 million for AlliedBarton in 2003. The company, which had its origins in SpectaGuard, is about three times the size it was when Perelman bought it.
