Emaar Malls PJSC (DFM:EMAARMALLS) is weighing options to sell fashion e-commerce business Namshi General Trading L.L.C that may include a listing abroad via a SPAC. An outright sale of Namshi may generate $600 million to $700 million in proceeds, while a listing through a special purpose acquisition company (SPAC) could be more lucrative, said a source. Emaar, which declined to comment, has approached some banks for potential advice on the deal, sources said.
