Nomura Holdings Inc.¡¯s besieged chief executive won a shareholder vote Monday, surviving a call for his ouster from the board following an information leak.

CEO Koji Nagai was re-appointed at an annual shareholder meeting alongside nine other nominees proposed by the company, Japan¡¯s biggest brokerage said in an emailed statement. The vote was held almost a week after Nomura announced several moves to placate investors following the leak and recent losses, including governance changes and a $1.4 billion stock buyback.

But those reforms ¡ª particularly tweaks to how it selects its top executives ¡ª are also likely to weaken the influence of management over who eventually succeeds Nagai, the bank¡¯s longest-serving CEO in three decades.
