Ann: Operational Evaluation Agreement signed with Globalsat Group, page-81

Point is they will need to pay for the second batch before the first batch are launched. Either that or construction on the second batch will have to stop for a time until the first batch are up and operational.
Given the first batch could potentially fund the 3rd or 4th batch, the gap in funding is pretty small and temporary which is why I say another CR isn't so unlikely. If not much funding is required and real money is about to start coming in there maybe little benefit to a joint venture.
