Elliott, which oversees $40 billion in assets, has held discussions with SoftBank's management and is calling on the company to buy back some $20 billion of its stock, improve its governance by increasing the independence and diversity of its board and improving transparency, sources said last month.
Son said on Monday he had not given enough weight to the opinions of investors and the company's independent board members, according to three sources who attended the meeting which was closed to media and provided details on condition of anonymity.
Son pointed to SoftBank's stock trading at a big discount to the value of its assets as an opportunity for investors to buy in.
