RE:Cash burn
I think they have ~3 months for the share price to recover before a very unpleasant refinancing becomes necessary. That's of course still (easily) possible, but will require a relatively fast end of the current crisis.
I am going back and forth here if I should buy back in now. Intrinsically, the value of the company seems much higher to me than the current valuation. But right now it looks a bit like it's not in their own hands to fulfill that potential.
