G.sachs is not claiming to be a owner of celsius. its claiming to be a loan giver to celsius. however if anyone in business knows G.sachs arranged the management switchover.
the new manager is a known 'liquidator" of weak companies. but even that is not an absolute. some liquidators also know how to recover companies.

as for g.sachs. before filing bankrupcy (via the puppetstrings) if that was the planned route they choose to go, g.sachs will pull out any good assets from celsius. and put in any bad assets g.sachs has. .. and then pull the string

but at this present moment this second. it can go both ways. a plan to close or grow celsius
