Mo is EVP at AT&T Business, he runs this shop and was thought of as being next in line to Anne Chow to be CEO.
An hour ago it was announced that he will leave AT&T Business and be a "SVP" reporting to Chris Sambar (who reports to Scott Mair) . He is replacing Bloodworth .
From being responsible for P&L for a $30 billion org to building out mobility infrastructure, and losing EVP status seems like a demotion.
