Deal windowAct nowNotice published 2 days ago

Preliminary proceedings. The preliminary administrator is securing the estate and generally cannot transfer the business yet — but this is when the bidder list forms. Being known now is why you get the call later.

Insolvency wage cover typically runs to about 2026-11-11 — that is the clock everyone is running against.

Typical sequence under the German InsO; not legal advice and not a statement about this case. The administrator runs the process.
