Credit Suisse has promoted Boon Sim, head of Americas M&A, to lead global M&A for the bank in a reshuffle of its teams advising US and European companies on takeovers, reported Reuters citing an internal memo. The role was previously held by Marc Granetz, who will become chairman of global investment banking.

Prior to his current position, he co-headed the bank’s technology group based in New York. He is a member of the bank’s investment banking management council and a member of the bank’s investment banking advisory committee, which oversees the rendering of M&A opinions and formal advice.

He has advised both multi-national and domestic clients on numerous M&Aassignments in transactions over $400 billion, including mergers, acquisitions, divestitures, spin-offs, joint ventures, special committee assignments, dual class and targeted stock plans, proxy contests and hostile transactions.

Reportedly, Andrew Lipsky, head of the Americas diversified industrial and services team, will lead Americas M&A. In Europe, Guiseppe Monarchi, the bank’s co-head of European technology, media and telecom, takes over as head of M&A for Europe, the Middle East and Africa (EMEA) from David Livingstone, who becomes CEO of Credit Suisse in Australia, reported the news agency.
