T-Mobile Misses Earnings Estimates Widely

T-Mobile the fastest growing mobile carrier

The mobile carrier added 2.3 million subscribers during the quarter, marking the 10th in a row in which it added more than 1 million subscribers. Of those adds, 1.1 million were branded postpaid net adds. T-Mobile added 843,000 branded postpaid phones and 595,000 branded prepaid subscribers.

T-Mobile’s service revenues increased 11% to $6.3 billion, while its adjusted EBITDA climbed 42% to $1.9 billion. The adjusted EBITDA margin rose more than 600 basis points to 30%. Net income was $138 million, compared to last year’s net loss of $94 million.

The mobile carrier’s branded postpaid phone average revenue per user remained stable at $47.99 as rising attach rates offset its focus on family plans and promotions. T-Mobile sold or leased 8.9 million devices during the third quarter, of which 8.1 million were smartphones. Branded postpaid churn fell 18 basis points to 1.46%.
