Normally I pay zero attention to this kind of thing, because it is invariably merely portfolio crossings or off-market transfers between related entities, but in this case these share were transacted on the CBoe exchange.

And the total number of shares involved, i.e., 33.4m, coincides almost exactly with NED Casey's declared shareholding.

Might just be coincidence.
But if he is the seller, then it appears the stock was sold in two lines, one of 30.84m shares (7.4% of the shares outstanding) and a smaller line of 2.6m shares (0.6% of the total)

But, as I said, I might be barking up the wrong tree.

I doubt we'll die not knowing.
