EchoStar has until Friday, July 6, to decide whether to present a firm offer for Inmarsat or drop the plan for six months based on the rules of the U.K. takeover panel.
The U.S.-based satellite group disclosed that it made a bid of approximately $7.05 per share on Tuesday that Inmarsat turned down a day after, saying the offer significantly undervalued the U.K.-based firm and its prospects.
The move came weeks after EchoStar revealed in a stock exchange filing that it secured a 3 percent equity stake in Inmarsat and nearly a month after the latter declined the U.S. firms first takeover offer.
