He might just be trying to reprice the deal at a lower price he now thinks is commensurate to the value. Things were necessarily rushed in the initial agreement due to leaks etc. He and his team have now had time to develop an operating plan. Keep in mind that there are several savvy hedge funds also investing in this deal and this may be driven by their concerns. There's also a possibility he'd just like to ensure the deal closes in a certain later time window. The composition of his personal wealth is complex and highly dependent on his equity holdings which have grown volatile recently.
