Firstly, the music catalog alone is worth more than the company, itself.
Second, it has barely been a year since the emax 'merger' and it seems that they are following through on everything they say they are doing. You asking me to point to something they've followed through on? I'd say everything!
Finally, the JV is one of several different avenues of business. Not all business deals are successful. As a business owner myself, I can tell you that (like most things in life) there is an 80/20 rule... 80% of business turns into crap, and the other 20% pays the bills. When one deal doesn't work, it doesn't concern me; If the board sat on their laurels after a deal fell through (or a subsidiary was suspended)... that would concern me.
