March 13 (Reuters) - Brookfield Asset Management Inc BAMa.TO said on Wednesday it will buy most of Oaktree Capital Management OAK.N in a roughly $4.8 billion deal, creating an alternative-asset manager that will challenge the likes of industry giant Blackstone (NYSE:BX) Group BX.N .
The decision by Oaktree, led by distressed debt investor Howard Marks, to sell a majority stake of itself comes after a sustained period in which its stock has underperformed the broader market.
Oaktree's stock is down around 13 percent in the last five years, even after a price bump on Wednesday following the deal's announcement. By comparison, the S&P 500 Index .SXP is up more than 50 percent over the period and Blackstone's share price is up 4 percent.
Brookfield approached Oaktree about the deal sometime during the fall season, a person familiar with the matter said.
Oaktree is the second U.S. alternative-asset manager to sell itself in recent years, since Fortress Investment Group agreed to be acquired by Japan's SoftBank Group Corp 9984.T for about $3.3 billion in 2017.
The deal is a bet by Brookfield, which currently focuses on private equity, real estate, infrastructure and renewable power, on the prospects for investing in debt, which makes up around 70 percent of Oaktree's assets under management.
"This transaction enables us to broaden our product offering to include one of the finest credit platforms in the world, which has a value-driven, contrarian investment style, consistent with ours," Brookfield Chief Executive Bruce Flatt said in a statement.
The combined businesses will have about $475 billion of assets under management, including debt, Brookfield said.
Industry leader Blackstone had $472 billion in assets under management at the end of 2018, though this does not include debt. Including debt, Blackstone's assets under management would be at least $650 billion, a firm spokesman said.
Oaktree shareholders can exchange each of their shares for either $49 in cash or 1.0770 Class A shares of Brookfield. Brookfield said the total amount will be paid in 50 percent stock and rest in cash.
The offer is a premium of 12.4 percent per Oaktree Class A unit to Tuesday's closing price, Brookfield said in a statement. The stock was up 12.2 percent in mid-afternoon trade. companies will continue to operate as independent businesses, while Marks, Oaktree's co-chairman, would join Brookfield's board of directors.
Oaktree shareholders, consisting primarily of its founders, certain members of management and employees, will own the remaining 38 percent of the company.
Starting from 2022, the remaining shareholders will be able to sell their remaining Oaktree units to Brookfield over time.
