Bethpage-based Altice USA, which was formed after global telecom giant Altice N.V. bought Cablevision last year, plans to go public.

The company has filed a prospectus with the U.S. Securities and Exchange Commission for an initial public offering. There is no indication of the stock price in the filing, or of how many shares the company plans to sell to the public.

Altice USA would continue to be controlled by its parent, Altice N.V., which is based in the Netherlands, according to the prospectus.

Altice USA would rank as one of the largest publicly traded companies on Long Island, with combined revenues of $9.15 billion for 2016, according to the prospectus.

That figure includes both the former Cablevision Systems Corp., which was based in Bethpage, and Suddenlink, a cable company that was based in St. Louis when it was bought by Altice N.V. in 2015.

Altice USA provides internet, cable television, telephone, proprietary content and advertising services to 4.9 million residential and business customers, the prospectus said, and was operating in 21 states as of Dec. 31.

On Long Island, Altice USA offers Optimum cable, internet, telephone service and public Wi-Fi, and Lightpath business services. It owns the News 12 Networks, “the largest and one of the most-watched 24-hour local news networks in the New York media market,” the prospectus said.

Altice USA had 16,000 employees at the end of the year, according to the prospectus.

It owns 25 percent of Newsday Media Group.

The Wall Street Journal, citing people familiar with the matter, said the IPO of Altice USA is expected to raise about $1 billion, and would value the entire company at more than $20 billion.

Since Altice USA was formed, it has “made significant progress in integrating the operations of Optimum and Suddenlink,” the prospectus said. The company said it has “upgraded our networks to nearly triple the maximum available broadband speeds we are offering to our Optimum customers” and increased speeds for Suddenlink customers. And it has begun a five-year plan to build a “fiber to the home” network to allow “more than 10 Gbps broadband speeds across our entire Optimum footprint and part of our Suddenlink footprint.” The measurement Gbps stands for gigabits per second.

The company said in the prospectus that it has “substantial indebtedness.” It said it had $20.5 billion in net debt — total debt minus cash — on Dec. 31.

Altice N.V. “will continue to control a majority of the voting power” of the stock of Altice USA after the public offering, according to the prospectus.
