In case anyone is interested in the end result, here's what happened to Osprey Medical (ASX:OSP):

• Delisted on 29 August 2022 at 20c (if I remember correctly), after a share consolidation earlier in the year.
• More complicated consolidation of shares.
• Anyone left with a fractional share after the various consolidations was paid out at AUD0.0025 (ie. a quarter of a cent).
• For a 99.9966537% loss from top to bottom. Less than 100%, so that's a plus! My loss was ``significantly'' better than that, at only 99.9924215%.
• Company now privately held, not clear who owns it. (Not me!)

It's a shame they couldn't make a business out of this, or at least sell their tech profitably to someone else. I hope that at least it does become the standard of care in avoiding kidney damage, and that would be some bonus to the world.
