Portnoy made the announcement via his Facebook page. Here is what he had to say, "It saddens me to announce that the 4 upcoming shows in Latin America this month supporting Halestorm will be my last with Adrenaline Mob.

"Unfortunately, I have scheduling conflicts that prevent me from being able to fully commit to the band's future activities at the moment. As I cannot be in two places at the same time, I don't want to hold them back and have to wait for my schedule to re-open up to resume activity.

"I'm very proud of what we started together and the music we made over the past two years and I wish the guys all the best in the future."
