So your 1 million shares will not be 100 shares but instead 0.1 share - I am not certain on the fractional shares but I believe it will round up so you will have 1 share of the new ACX company.
The key is that all of the registrant pre-merger common shares (that will be fully diluted) will account for 10% of the ACX common shares.
They do this with the intention of taking out all of the current shareholders.
SO they are telling you exactly what they are going to do - and the people posting about loading up before the merger didn't read or understand the 8-K.
