They closed because they lost money for 40+ years straight, or close to it. Aldi never really adapted their stores to Danish habits in the same way that Lidl has. The design of their stores always made you feel like you traveled back in time to the 70s or early 80s. They did to modernize in the later years, but it was simply to late. The stores still smelt weird though.
It may also be partly due to Aldi reluctance to carry brands beyond their own. For some items Danes don't care, but if you then can't get the brand name cereal or ketchup, then you have to go somewhere else anyway. The Danish supermarket space is insanely competitive, in regards to price, so Aldi just didn't have much of an advantage over local discount stores anyway, at least not enough that you'd bother splitting your shopping between two stores.
I believe they lost €125m+ per year in the final years, loses that need to be covered by Aldi Nord in Germany. In the end they just didn't want to keep losing money. REMA1000, from Norway, bought a large number of the stores. Not sure why, they look nothing like REMAs own stores, and in some places they are literally across the street from an existing store.
