T-Mobile USA CEO Philipp Humm has resigned from his position at the helm of the nation's fourth-largest wireless provider after two years in the role, the company said in a statement.
Humm oversaw T-Mobile during its doomed negotiations to merge with AT&T, which regulators blocked over antitrust concerns. During his tenure as CEO, the carrier has steadily shed subscribers, losing 510,000 contract customers in the first quarter of this year.
T-Mobile USA said in a statement that Humm is "going to pursue a career outside of Deutsche Telekom [T-Mobile USA's parent company] so as to reunite with his family, which stayed back in Europe."
T-Mobile chief operating officer Jim Alling will serve as interim CEO while the company conducts a search for Humm's replacement.
“Philipp Humm has given the company some important initiatives over the past years: Under his leadership the cost situation at T-Mobile USA has vastly improved and he led the company during a difficult phase regarding the planned merger with AT&T,” said Deutsche Telekom CEO René Obermann. “Now we need somebody who can convert initiatives into market-successes.”
