He might just be trying to reprice the deal at a lower valuation he thinks is commensurate to the potential. 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 hedge funds also co-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.
