­USA based MetroPCS has reported third-quarter revenues that rose by 4 percent to US$1.26 billion, and a net profit that jumped by 178% to US$193 million.

The net income includes a US$53 million one-off gain on settlement related to certain securities that was recognized during the quarter. Excluding the one-off gain, profits would have still doubled compared to a year ago.

The company is currently in the process of a merger with T-Mobile USA.

Roger D. Linquist, Chairman and Chief Executive Officer of MetroPCS, said, "With a primary focus on generating Adjusted EBITDA and cash flow during the third quarter, we are pleased to report the highest Adjusted EBITDA margin in Company history of 41.5%."

"During the fourth quarter, we plan to focus on re-energizing subscriber growth, which we expect will put incremental pressure on our CPGA and Cost per user (CPU)."

The subscriber base however fell by 2% to 8.98 million as it lost a net 312,291 customers in the quarter. One million of its customers are now connected to the LTE network.

Average revenue per user (ARPU) of $40.50 for the third quarter of 2012 represents a decrease of $0.30 when compared to the third quarter of 2011. The decrease in ARPU was primarily attributable to promotional service plans partially offset by continued demand for LTE service plans.

MetroPCS currently expects to incur capital expenditures in the range of $900 million to $1.0 billion on a consolidated basis for the year ending December 31, 2012.
