They don't need to PR it but I would think that they would. The transfer agent would have the share count and can give this information out if the company does not put a "gag"........
For me the buy back is a much smaller part of the puzzle. Distribution and sales..... this is the key!
Considering the significance of it, the interest from shareholders, and the additional 150 million shares that went in to the O/S, I would hope he is smart enough to PR the exact details of the return.
