Frontier Communications is up a whopping 50% in after-hours trading.
The stock jumped more than 1% to $28.60.
Frontier is currently up almost 40% in the past month, as investors look for better earnings.
The company reported revenue of $2.1 billion in Q4, which is up from $2 billion in the same period last year.
The growth in the revenue comes from the company’s fiber-optic broadband service.
The wireless carrier also said it will start deploying its 5G wireless network later this year.
Frontier also said its revenue grew to $4.6 billion in FY18 from $3.6 million in FY17.
In addition to fiber-to-the-home, Frontier said it sold 1.5 million wireless customers in FY16, up from 1.3 million in the previous quarter.
Frontier will begin deploying 5G in the United States later this summer, and the company expects that to have a significant impact on revenue.
The acquisition of the cable company, however, is not without its problems.
The merger of the two companies is currently under review by the Federal Communications Commission.
The FCC said in a statement that the deal would be subject to “market conditions” that could be unfavorable.
The commission also said that it is considering whether Frontier has adequate market power to serve the market, and whether Frontier is able to serve as an effective competitive alternative to Comcast.
