A tweet from the band's official account today said "we have now come to the end of our incredible time together".
It was sent shortly after the five singers came off stage in Liverpool, marking their last performance together as a group.
The five-piece reunited for the 12-date UK tour after spending three years on solo projects.
They played the SECC in Glasgow earlier this month.
Today's tweet said: "Dear Alouders, we just want to say from the bottom of our hearts Thank you!!
"This tour has been an amazing experience and the perfect chance to say thank you for being on this journey with us through a decade.
"It has far exceeded any of our dreams!
"Your love and support will stay with us forever but we have now come to the end of our incredible time together. Love you lots."
