Sprint reported quarterly revenue on Friday that beat analyst estimates, as the No. 4 U.S. wireless carrier raised its free cash flow outlook for the 2017 fiscal year.
The company has sought to strengthen its balance sheet by cutting costs and mortgaging a portion of its airwaves and equipment, but industry analysts have raised concerns about how it can adequately fund network improvements.
Sprint now expects $2.5 billion to $2.7 billion in operating income, up from its previous estimate of $2.1 billion to $2.5 billion. It expects adjusted free cash flow of $500 million to $700 million, compared to previous estimates of breaking even.
Shares jumped 4.9 percent to $5.35 in premarket trading.
The company reported net additions of 184,000 phone subscribers who pay a monthly bill in the quarter, compared to additions of 368,000 a year earlier.
“Volumes came in surprisingly strong while profitability and cash flow were also better,” analysts at Jefferies said in a note.
Net operating revenue in the third quarter ended Dec. 31 was $8.24 billion, down from $8.55 billion a year earlier.
Sprint reported quarterly net income of $7.16 billion, or $1.79 per share, due to the impact of federal tax reforms, after a loss of $479 million, or 12 cents per share, a year earlier.
Excluding the impact of tax cuts signed into law by U.S. President Donald Trump late last year, net income was 3 cents a share.
According to Thomson Reuters I/B/E/S, analysts had expected revenue of $8.15 billion and a net loss of 4 cents a share.
