Not sure if anyone has talked about this yet, but the Fraser Group have published their 22/23 accounts - this is the year that included their purchase of the arena.
I am a mere amateur, but I was curious and had a look at them. It looks like ownership is under a subsidiary called Coventry Arena...
Not sure if it sold out but due to a very, very, very last minute work commitment I can't make it today, but I have two tickets spare and a friend going to the ground who you can pick them up from.
Let me know if you're interested.
