AST stock surged on $550 million financing to support big spectrum deal

A week ago Sunday, AST announced that one of its subsidiaries had secured $550 million in funding to support its deal to license wireless spectrum from Ligado Networks. Through the licensing deal, AST SpaceMobile will receive access to 40 MHz of L-Band MSS spectrum in the United States and Canada. The licensing deal extends for more than 80 years and also potentially grants AST access to an addition 5 MHz of category spectrum in the U.S. market. Investors appear to be happy with AST's financing moves to support the deal and bid the company's stock higher in each of last week's trading days.

What's next for AST SpaceMobile?

On the heels of recent gains, AST SpaceMobile now has a market capitalization of roughly $14.4 billion and is valued at approximately 37 times this year's expected sales and 234 times expected earnings. While the company has a highly growth-dependent valuation, it also appears to be in the early stages of a major new growth phase.

The company's satellite-based cellular broadband network has the distinction of already being compatible with existing mobile devices without the need for add-ons or modifications, and the service could wind up having a disruptive impact in the consumer telecommunications industry. Outside the consumer market, investors are also excited about the company's potential to win deals with U.S. defense agencies and related contractors.
