- The deal positions Charter as the fastest-growing mobile provider in its footprint, enhancing its competitive edge.

Charter has wrapped up its acquisition of Cox Communications and its deal to acquire Liberty Broadband, accelerating its position in the broadband and business services markets.
Initially, the $34.5 billion megamerger with Cox was announced in May 2025, with Charter, the second-largest cable company in the U.S. behind Comcast, acquiring Cox, another cable giant with 6 million subscribers. The FCC approved the deal earlier this year.
Charter said these deals will create a more expansive broadband and video company and the fastest-growing mobile provider in its footprint.
Next year, the combined company will take on the Cox name but will continue to operate under the Spectrum brand across all markets. The company will also remain headquartered in Stamford, CT, while maintaining a significant presence in Atlanta, GA.
From a top management perspective, Alex Taylor will become Chairman of the combined company board, while Eric Zinterhofer has been named the lead independent director of Charter's board.
In addition to Taylor, Cox Enterprises has appointed Dallas Clement and Mark Greatrex to Charter's 13-member board.
Chris Winfrey, who will continue in his role as Charter’s President and CEO and board member, said the merger with Cox reflects the service provider’s need better to position its competitive rank in broadband and business services.
"The market has changed considerably over the past decade, and regional providers like Spectrum are competing with national and even global connectivity and entertainment companies,” he said in a prepared statement. “Today, with expanded scale, we are better positioned to compete and continue investment in our products and services, tools and platforms, and to further the capability and reach of our Spectrum Fiber Broadband Network."
Raising broadband, wireless stakes
A key element of the deal with Cox is to gain a larger broadband base, one that Charter has been seeing greater challenges from ILECs’ fiber broadband and fixed wireless access (FWA).
Through its Cox deal, Charter’s combined footprint will reach 45 states and 69.5 million total locations passed, with the Spectrum brand officially rolling into Cox markets by mid-September 2026.
Charter will add 12.3 million Cox locations to Charter's existing 57.2 million, creating a massive 69.5 million home and business reach.
Still, the near-term reality for Charter, like other cable operators, is continued broadband customer churn, a theme that continued into the second quarter. During the second quarter, Charter lost 172,000 residential broadband subscribers, bringing total internet customers to 29.4 million amid fiber and fixed-wireless competition.
However, wireless was a bright spot for Charter. The cable MSO added over 406,000 Spectrum Mobile lines to reach 12.5 million total lines, pushing mobile service revenue up 18.9% to $1.1 billion.
To welcome Cox customers, Spectrum is offering a free year of mobile service to Cox internet customers who don’t already subscribe to Cox Mobile; the first of many benefits Spectrum will offer. Spectrum said it plans to launch its full suite of products to all consumers, including existing customers, in former Cox markets, offering Spectrum’s simple, transparent pricing and packaging, greater value, and more opportunities to save.
The company claims what differentiates Spectrum Internet and Spectrum Mobile from standalone 5G providers is that they both work together over its Spectrum Fiber Broadband Network and are supported by approximately 45 million Wi-Fi access points across the country.
Winfrey said existing Cox and Charter customers won’t see any major effect from the merger.
“As of today, for customers, there's really no change except in the market for new customer acquisition: there's better internet pricing, and there's a free mobile line for a year and then the best pricing in the marketplace thereafter,” he said. “So that's already started.”
He added that in about a month, “we'll rebrand all of the Cox markets, including the trucks, and on the bills have a transitionary period that Cox is now Spectrum.”
Enhancing broadband infrastructure
While Charter did not lay out specific plans, the service provider noted that it will continue to follow the existing upgrade paths set by itself and Cox Communications.
Charter will continue to make upgrades that incorporate high splits and a path to DOCSIS 4.0. Both Charter and Cox Communications have used mid-split architectures across their HFC networks to enhance uplink performance.
A mid-split configuration increases upload capacity to support up to 300 Mbps, bridging the gap between older low splits and future symmetrical high splits.
“Cox is pretty far along with this mid-split upgrade, and they've done some high-split upgrades similar to us, which can get you upward upstream speeds of 300 megabits per second and sometimes higher,” Winfrey said. “This gives us a very long runway for the type of product capabilities that we see today.”
He added that it can also convert what it has “from a mid-split to a high-split environment, so we're not in a rush to go do that today.”
And because a large portion of Cox cable modems in the market are set to mid-split, Winfrey noted: “to the extent you went and did high split in Cox, it would really be for new modems to new customers on the increment.”
At the same time, Charter plans to bring back its capital spending down as it winds down its broadband expansion.
“We're focused on bringing our capital expenditure back down after a high period to a normalized level,” Winfrey said. “And we're doing that as we now, essentially, at the end of this year, we'll have completed our broadband expansion at length of spectrum.”
He added that “as we get through next year, we’ll complete the high-split upgrade in the legacy Spectrum footprint.”
Enhancing business services
Along with its consumer sector, the combination of Charter and Cox creates a more powerful business service provider with a larger fiber network and more service assets.
Businesses of all sizes throughout the Spectrum footprint will benefit from Spectrum Business's combination with Cox Business's relationships with businesses. The deal also includes Segra, Cox's regional, fiber-based provider serving commercial enterprise and carrier customers, and RapidScale, its managed, cloud-based services provider.
According to an SEC filing on its merger with Cox, Charter paid $3.5 billion in cash for Segra and RapidScale, which is structured separately from the equity consideration used for the residential cable business.
Winfrey said RapidScale and Segra will continue to operate as part of its broader business services portfolio.
“I think a bigger opportunity for both RapidScale and for Segra is where there is overlap inside of some of the Spectrum network footprint,” he noted. “I think there’ll be more selling opportunities for both as a function of our size and bringing them together. And we’re going to leverage the expertise that we have with Cox Business, the Spectrum Business, to continue to grow those businesses.”
