"This never gets old! T-Mobile finished another year with record breaking financials and our best-ever customer growth! Record revenues, strong net income, record Adjusted EBITDA, our lowest-ever Q4 postpaid phone churn that was better than AT&T for the very first time!" said CEO John Legere. "T-Mobile is competing hard and winning customers - and we continue to deliver results beyond expectations. Our 2019 guidance shows that we expect our incredible standalone momentum to continue!"

T-Mobile shares rose 2% to close at $68.28 in Thursday's trading, leaving the stock's three-month decline at about 4%.
