Absolutely old_schooler. New rules have come into play for stocks on the Frankfurt exchange.
As you already know, each tier on the Frankfurt, has certain compliance rules for the company to adhere to.
I believe Ticker is ready to move up to the next tier on the Frankfurt Exchange which will require audited financials. I believe Ticker is already working on this and a prospectus.
The secret to profitable investing is to buy into well-run companies at the beginning of their earnings growth cycle—before Wall Street takes notice and bids up the stock price.
My opinions are my own. You have to decide and do what's best for you.
