RE:Yikes what a mess! The arbitrage on this deal is ten cents today, or in other words if the deal went thro at todays Fortuna share price and stayed there you would get $2.10 for your RoxG share not the $2.00 that was todays price.
Fortuna's market cap has fallen $440 m since the deal was announced and if RoxG's share price was $1.7 before any word of the deal was leaked, then RoxG market cap has risen by $112m.
Perhaps there is some thinking that if the deal doesn't fly then RoxG will go back to $1.7 , and hence the 10 cent arbitrage. And no one seems to think there will be a better offer, or RoxG should be at least at zero arbitrage, and I would agree a higher offer seems highly unlikely. And some seem to think the deal might not complete which I think is also highly unlikely. So I would conclude that RoxG is a great buy at this price with that 10 cent difference.
