Speculation from the linked article1 Dec 2017 19:53
Lifted from the article linked below by steve4583 shows plenty of upside ahead:
�We believe there is merit in doing the merger analysis. We conclude that a �10 per share offer balances all interests (though we estimate EchoStar could bid as high as �15 and still see year 3 Free Cash Flow per share accretion pre-synergies). Our analysis suggests the urge to finally �pull the trigger� on an offer must be becoming overwhelming.�
The bank stresses that its discussion is hypothetical and �is not based on non-public information / confirmation from the issuer or another party, and does not otherwise reference an impermissible rumour.�
The bank adds that it could see EchoStar paying up to a 30 per cent premium for Inmarsat, or even more in order to secure the business."
