RE:RE:I wouldn't be worried about itAbsolutely, that's quite likely. It will have to be vetted and approved by the exchange before it can be released so it may take some time.
I suggest that the actual release had probably already been drawn up and was slated to be announced either after the close or before the open tomorrow, but the "interest" in the US forced the exchange to contact the company.
Whatever it is, you can be sure it isn't bad news.
