Sculptor Capital Management Inc. said major shareholder and founder Dan Och and his group agreed to a sweetened deal for the struggling hedge fund from Rithm Capital Corp.

Rithm’s amended offer increased the bid to $12.70 a share from $12.00, Sculptor said in a statement. It values Sculptor at about $720 million.

Och’s support potentially puts an end to a bidding war that pitted Sculptor against Saba Capital Management founder Boaz Weinstein and a group of billionaires, who most recently said they would pay $13.50 for the hedge fund firm.

“We are pleased to reach this amended agreement with Rithm, which delivers a highly attractive premium to Sculptor stockholders,” Sculptor’s board chair, Marcy Engel, said in the statement, adding that she appreciates the support of Och and the former executive managing directors who are voting with him.

Rithm announced in July that it had reached an agreement to acquire Sculptor for $11.15 a share. Weinstein’s group, which includes billionaires Bill Ackman, Jeff Yass and Marc Lasry, increased its offer multiple times since making an initial unsolicited bid of $12.25 a share in August.

Less Certainty

The main difference between the competing offers, other than price, was that Weinstein’s group planned to demote the firm’s head, Jimmy Levin, from his post as sole chief investment officer, while Rithm said it would keep the status quo.

While the Weinstein bids have always exceeded Rithm’s, Sculptor never deemed them to be superior.

Sculptor said the billionaire group’s bid brought less certainty of the deal closing, in part because of the need for a certain percentage of the firm’s hedge fund clients to agree to stay. Weinstein eventually reduced the client consent level to zero, meaning he would go through with the deal even if all the investors pulled their money. Even then, Sculptor continued to support Rithm’s bid.

Both sides have vied to win support from Sculptor founder Och, one of its biggest shareholders, who has been locked in a bitter feud with Levin, his onetime protege, over compensation.

Under the new agreement, Och and his group of former Sculptor executives agreed to vote their 15 percent of outstanding shares for the Rithm deal, and to dismiss litigation related to the transaction.

Rithm amended its agreement with Levin, saying if he decides to leave the firm, he would forfeit unvested deferred compensation and retention awards, and face a 12-month non-compete agreement.

It also agreed to waive a condition that the firm’s hedge fund clients consent to the deal, as long as it closes by Nov. 17, the day after the scheduled shareholder vote.
