Interesting to see Regal sold a sizeable chunk on the 19th December when Strike proposed 1:1.
Must have assessed more bids were likely to be forthcoming? Then sold a small portion for cash, whilst indicating to STX intention to accept.
Might also indicate Ellison's intervention was a recent development needed to secure effective control for Min/Gina, prior to Strike's offer becoming formally open? i.e. given Ellison can buy as many as he wants on-market until reaching 20%.
