SM Entertainment's rookie group EXO-K has wrapped up their Korean 'MAMA' promotions to outstanding achievements on the charts.

Since its release on April 9th, their debut mini-album 'MAMA' has sold a total of 100,612, a significant number considering that they're a rookie group that has managed to cross the 100,000 mark in just two months.

This number added with EXO-M's 'MAMA', which amounts to a total of 51,643 units, brings the grand total to 152,255 units, making them the biggest selling rookie group of 2012 so far.

Their success should come to no surprise since they had 100 days of online promotions before their debut, along with CF deals for brands like 'Calvin Klein' and 'Ivy Club' shortly after their debut.

The members expressed, "Our debut promotion was a precious time where we were able to learn and feel many things. Thank you to all of our fans for their support. We will use this experience as a stepping stone to improving ourselves in the future. We ask for your continuing interest and support."

Having concluded their promotions last week, EXO-K will be focusing on their international activities and productions for their next album.
