Just Eat was originally founded in Denmark but moved to the UK
Just Eat was founded in 2000 in Denmark, then moved to the UK in 2005. It floated on the London Stock Exchange in 2014 and acquired by Takeaway.com (Thuisbezorgd.nl). It's now Just Eat Takeaway.com and trades on the LSE and Euronext. The head office is in Amsterdam now as well, but the whole UK engineering team is still in London and Bristol in the UK.
So the parent company is Just Eat Takeaway.com but then it's Just Eat in the UK (and much of Europe), Takeaway.com in the NL (well, Thuisbezorgd.nl), and a few other names around the globe like Menulog (AU/NZ), and Skip the Dishes (CA).
I read it as "Just Eat, takeaway" not as a concatenated company name which apparently is "JET" on the LSE

So you can have a company that is incorporated in the Netherlands, but which has its principal place of business in London. Depending on who you’re talking to, this is either a Dutch business or a British business.
A maneuver like this would often be done for tax purposes.
