Blackstone Group LP (BX) is looking into a possible deal to buy Anheuser-Busch InBev NV's (BUD) theme parks, a person familiar with the matter said Wednesday.

InBev, which bought Anheuser-Busch last year, has been looking for months to find a buyer for theme parks operated under Busch Entertainment Corp. The amusement parks include SeaWorld and Busch Gardens.

Any deal would allow InBev to pay down debt incurred from its $52 billion acquisition of Anheuser-Busch. The deal would also expand Blackstone's global theme-park holdings, which already includes stakes in Universal Orlando and Madame Tussauds wax museum.

The acquisition of Anheuser-Busch's theme-park holdings would fold nicely into Blackstone's London-based Merlin Entertainments Group. There has been talk that Blackstone intends to list the theme-park operator on the London Stock Exchange sometime this year.

An initial public offering for Merlin, which operates Legoland theme parks, could be made more enticing with the addition of Busch Entertainment. Analysts have estimated a Busch sale could fetch between $2 billion and $5 billion.

In addition to Merlin, Blackstone owns 50% of Universal Orlando alongside NBC Universal.

No deal was expected imminently.

Anheuser-Busch InBev couldn't be reached for comment.
