ozgem, yes correct, you will automatically see your holding reduce to 1/25th in number of shares so 25000 shares becomes 1000 new shares.
Out of interest I have just looked at trades since Xmas and at a very rough guess the buys are 4.7m shares and the sells 1.8m. This is still small change when there are 695m shares currently but shows the heavy weighting towards buys.
With all the aquisitions last year and the current one, Cytomyx is becoming a major player and is receiving a good re-rating. I personally can't belive PRM's share price and valuation which seems like fantasy time. With CYX valued at 11.5m which will become 15m soon after the double placing, there could be huge upside. And don't forget this has products which sell and make a profit, so it's a different league to PRM.
