Chen opened up about EXO's contract with SM Entertainment.

On the April 10 airing of MBC's 'Radio Star,' the MCs asked if it's almost time for EXO to renew their contracts. Chen replied, "We have about 3 years left." 

The MCs then asked, "Do all members have the same contract renewal dates?" Chen answered, "Yes, it's all the same. We still have time so we are not thinking about that yet and just enjoying promotions."
