Help understant ABMD and SVB

Hi All, will combine two independent questions here.

1. What is the potential future of SVBQ stock? Is there any chance of recovery? I thought SVB was bailed out, yet the is almost zero.

2. I also had some ABMD stock. It got acquired buy J&J, but the stock converted to ABMD.CVB which is also very low in price, not sure if it is tradable. Would appreciate if someone could explain what are the potentials there?

Thanks you!
