Now what NPA says the new IPO, tickered "ASTS," will come public with a $1.8 billion market capitalization and a $1.4 billion enterprise value, of which $462 million will be cash that AS&T can use to build its business. The company's aim will be to address a $1 trillion need to enable cellphones that are already in existence to communicate with each other via satellite. Those are some big numbers, and they may be the reason that investors in other "space stocks" are getting excited about the emerging space economy. The more money that pours into this sector, so the thinking may go, the more money that will be allotted to space companies of all stripes.
