Keiichi Masayasu, a partner in our M&A/corporate practice group, handles a wide range of corporate matters, including domestic and international M&A transactions, joint ventures, private equity, corporate governance, and shareholder meetings, both in normal and emergent phases, focusing on takeover defense and shareholder activism.
He advises clients on preventative measures, such as strengthening governance, before activist strikes or hostile takeovers. He has extensive experience in responding to letters, meeting requests, and white papers from activists, and other activist campaigns, as well as dealing with shareholder proposals, shareholder requests to convene extraordinary shareholders meetings, proxy fights, hostile takeovers, and other unsolicited offers/bids.
He has taken on the challenge of developing legal practices, including designing takeover response policies adopted in emergent phases (emergency poison pills). He has researched and authored publications on cutting-edge theories and practices in these areas, while providing solutions that meet client objectives.
