United Technologies announced its $US30 billion acquisition of Rockwell Collins Monday, in a deal that would create one of the largest airline-equipment suppliers in the world.
Wall Street bankers are set to make a fat payday of as much as $US105 million on the mega-deal.
Morgan Stanley will haul in an estimated $US35 million to $US45 million for advising United Technologies, according to Jeffrey Nassof, director of consulting firm Freeman & Co.
JPMorgan and Citigroup will share an estimated $US45 million to $US60 million for advising Rockwell Collins.
The aeroplane parts makers, which spent the last month trying to reach a deal, are expected to have combined sales of nearly $US70 billion in 2017.
The deal is expected to close in the third quarter of 2018.
