Boeing Co (BA.N) is scrambling to find alternate financing for a satellite contract worth “several hundred million dollars” that was scuttled by privately held commercial satellite provider ABS due to uncertainty about the future of the U.S. Export-Import Bank, three sources familiar with the matter said on Tuesday. ABS told Boeing, the largest U.S. exporter, that it would have to consider non-U.S.-based producers to build ABS-8, given the absence of U.S. export credit financing, the sources said.
