Shares of T-Mobile US rose Wednesday morning after the telecommunications company's fourth-quarter results came in above what analysts had expected.

T-Mobile (TMUS) reported $2.98 billion, or $2.57 per share, in net income on $21.87 billion in revenue for the final quarter of 2024, with each metric topping estimates. Analysts had expected $2.63 billion, or $2.26 per share, in profits on $21.31 billion in revenue, according to estimates compiled by Visible Alpha.

"T-Mobile delivered another monster Q4 that punctuated an amazing growth year with best-in-class results across wireless and broadband,” T-Mobile CEO Mike Sievert said.

Sievert noted that T-Mobile had its lowest full-year churn rate for postpaid phone subscribers on record, and said it recorded its third straight year of at least 3 million postpaid phone net additions. The company recorded 903.000 postpaid phone net additions and 428,000 net internet customer additions, each above the 859,810 and 402,000, respectively, that analysts had expected.

Looking ahead to 2025, T-Mobile expects to record 5.5 million to 6 million net new customers, but did not provide a profit forecast because of the "high variability and difficulty in predicting" factors like tax expense and interest expense, which impact net income.

T-Mobile joins telecommunications rivals AT&T (T) and Verizon (VZ), which each topped estimates in their own fourth-quarter results over the last week.

T-Mobile shares were up more than 6% in premarket trading Wednesday, and entered the day up 35% over the last 12 months.
