Nomura’s Asia ex-Japan co-head of mergers and acquisitions has stepped down after six years with the bank as part of a leadership reshuffle.

Apoorva Shah has left the bank, according to a «Reuters» report citing unnamed sources, as part of a reshuffle that has made Chou Pei Shen the sole head of the unit.

Shah previously reported into Chou who joined Nomura from UBS in January as a managing director and co-head of M&A alongside Hajime Higuchi as the other co-head and head of international M&A after relocating to Singapore in late August. The Hong Kong-based Chou will continue to report to Asia ex-Japan head of investment banking Kenji Teshima and the global head of M&A Shinsuke Tsunoda.

At UBS, Chou was the co-head of all industries group and head of natural resources for Asia.
