Charter Communications is heading into a tougher stretch, according to RBC Capital Markets, which expects the cable giant's broadband subscriber losses to worsen over the next two years. The firm says the pending acquisition of Cox Communications—expected to close in mid-to-late August—could mark the point where Charter starts cutting costs more aggressively and pulling back on share buybacks as customer losses mount.
Broadband slowdown deepens
Charter has been losing broadband customers for several quarters as competition from fiber-optic providers and fixed wireless services intensifies. The company's legacy cable network faces pressure from rivals offering faster speeds and more flexible pricing. RBC's analysis suggests the trend will not only continue but accelerate in 2026 and 2027, with subscriber losses exceeding current expectations.
The Cox deal, announced earlier this year, is meant to strengthen Charter's position by adding scale. But RBC warns that integrating a large acquisition while subscriber numbers are sliding could force management to make tougher choices. The firm expects Charter to implement deeper cost cuts—potentially including layoffs or reduced capital spending—and to reduce the pace of its stock buyback program to preserve cash.
What the Cox deal means
Charter's acquisition of Cox Communications is a major bet on consolidation in the cable industry. By combining two of the largest cable operators in the U.S., Charter aims to improve its competitive position against telecom giants like AT&T and Verizon, as well as newer entrants like T-Mobile's fixed wireless service. The deal is expected to close in late August, pending regulatory approvals.
However, RBC's note suggests the timing is risky. With broadband subscriber losses already a concern, adding Cox's operations—which may also be losing customers—could compound the problem. The integration process itself can be disruptive, and the cost savings from the deal may take longer to materialize than investors hope.
For context, Charter has been investing heavily in network upgrades, including its shift to all-fiber infrastructure and the rollout of DOCSIS 4.0 technology, which promises faster speeds. But these investments take time to pay off, and in the meantime, the company is bleeding customers to competitors that already offer fiber-to-the-home or low-cost fixed wireless plans. Some analysts see broadband upgrade tailwinds for the industry, but Charter's specific challenges may delay the benefits.
What it means for investors
For everyday investors, the key takeaway is that Charter's broadband business faces a prolonged period of weakness, and the Cox deal could amplify the pressure. When a company cuts costs and reduces buybacks, it often signals that management is bracing for lower profits. Share buybacks have been a significant driver of Charter's stock price in recent years, so a reduction could weigh on the shares.
Investors should also watch for signs of how Charter plans to stem the subscriber losses. The company may need to offer more aggressive pricing or promotions, which could squeeze profit margins. Alternatively, it could accelerate its network upgrade plans to better compete on speed and reliability. Either way, the next few quarters are likely to be challenging.
RBC's warning comes amid a broader shift in the telecom and cable sector. Investors are increasingly demanding profits from AI and tech spending, and cable companies are under similar scrutiny to show that their capital investments are generating returns. Charter's ability to navigate the broadband slowdown while integrating Cox will be a key test.
For now, the message from RBC is clear: Charter's broadband slide is not letting up, and the Cox deal could be the catalyst for deeper cost cuts and a less shareholder-friendly capital allocation strategy. Investors should keep a close eye on the company's next earnings report and any updates on the integration timeline.
