From my understanding the head office and executives there were actively hostile towards the US subsidiary and did many underhanded and ethically questionable things in an attempt to get them shutdown. Revenue made from the US subsidiary was attributed to the head office's books in the EU but not the the liabilities causing serious budget problems until it started to fall apart. Notice all the unpaid entities are connected to the US subsidiary? Yeah now EK has to scramble to get enough cash on hand to pay all those liabilities that was being masked by the tactics of the head office.
As for the business itself, as long as it's business model is sound, which it seems to be, then they'll be ok. Business's being cash short due to seasonal revenue is pretty common and there are many financial tools available to smooth that over. Unfortunately financial entities frown when you have a line of creditors due to late payments and are very hesitant to approve bridge and short term capital loans in that situation. These things really need to be arranged ahead of time and it looks like the EU office, in their attempts to shut down the US office, didn't have an arrangement.
Also guys, the current CEO is the owner / founder, he previously hired a different CEO to handle the business side. That other CEO was sacked after this nightmare was brought to the attention of the owner / founder.
