Comcast Q3: Broadband Bleed Accelerates as Peacock Profits and Restructuring Looms

Key points

• Comcast lost 144,000 residential broadband customers in Q3 2026, a significant increase from the 91,000 lost in the same quarter last year, bringing total residential broadband subscribers to 28.3 million.
• The company lost 274,000 video customers, reducing the total base to 10.4 million, while adding 368,000 wireless lines, a slowdown from the 414,000 added in the prior year.
• Peacock streaming service posted $261 million in adjusted EBITDA on $1.8 billion in revenue, marking its second consecutive profitable quarter, with 48 million paid subscribers remaining flat quarter-over-quarter.
• Comcast plans a restructuring resulting in over $1 billion in charges in Q4, focusing on the cable division and expanding AI agents for customer service, which have already reduced contact rates by 20%.
• The company is on track to complete the spinoff of NBCUniversal and Sky by mid-2027, creating two separate publicly traded entities, while the Versant spinoff was completed in January 2026.

Background

Comcast first reported net residential broadband losses in Q2 2022, ending a 20-year streak of growth. In Q1 2025, losses accelerated to 183,000 customers, prompting co-CEO Mike Cavanagh to admit the company was not 'winning in the marketplace.' The company subsequently introduced unlimited data plans and five-year price guarantees starting at $45/month to retain customers, but losses continued. The current restructuring follows the January 2026 spinoff of Versant, which included cable networks like CNBC and USA Network.

How outlets are covering it

Ars Technica and The Hollywood Reporter emphasize the 'irrational' pricing from competitors, with Comcast CFO Jason Armstrong citing $30-$40 fiber offers as unsustainable given deployment costs. Ars Technica highlights the shift to AI agents and job cuts in customer service as a response to shrinking cable bases. CNBC and Deadline focus on the financial success of the media division, particularly Peacock's profitability and the box office success of 'The Odyssey,' which helped offset connectivity losses. Deadline notes that while broadband losses were expected, the wireless line additions missed analyst estimates, whereas CNBC highlights that overall earnings beat expectations due to media strength. All sources agree on the strategic pivot toward mobile and the impending NBCUniversal spinoff.

Why it matters

Comcast's struggle to retain broadband customers signals a fundamental shift in the US telecommunications market, where fiber and fixed wireless are eroding the dominance of legacy cable providers. The company's decision to invest heavily in AI for customer service and mobile convergence reflects a broader industry trend toward cost-cutting and digital transformation. The successful profitability of Peacock and the planned spinoff of NBCUniversal suggest that media assets are becoming the primary value drivers for legacy cable companies, while connectivity businesses face intense price pressure and margin compression.

What to watch

Investors will watch for the specific details of the over $1 billion restructuring charge in the Q4 2026 earnings report. The market will also assess whether Comcast's mobile growth strategy can offset continued broadband attrition. The completion of the NBCUniversal and Sky spinoff by mid-2027 is the next major milestone, which will determine the long-term valuation of the two resulting entities. Additionally, the performance of Peacock in Q4 2026 will be critical, as management warned that future quarters may be 'lumpy' due to varying subscription rate increases.
