T-Mobile beat expectations for its fourth quarter earnings report, posting revenue of $19.8 billion and earnings per share of $0.74. Analysts expected revenue of $18.9 billion and EPS of $0.57.

The Bellevue, Wash.-based wireless company added a net total of 1.4 million customers in the quarter, topping Verizon and AT&T. It now has a record-high 103.4 million total customers.

Shares were up more than 2% in after-hours trading. T-Mobile stock is up more than 40% over the past year.

T-Mobile’s continued growth follows the company’s $26.5 billion merger with Sprint, which was completed last year after a lengthy legal battle and extended regulatory review. The acquisition is helping T-Mobile build out its 5G network, which it claims is the largest and fastest in the U.S.

Last month T-Mobile launched its new home internet service as part of the latest “Un-carrier” move and in March unveiled 5G wireless routers.
