Comcast (CMCSA +4.53%) generated a record $19 billion in free cash flow (FCF) in 2025 and returned nearly all of it to shareholders. Yet a significant portion of that cash comes from its declining broadband business, which lost over 700,000 domestic customers as fiber and fixed wireless competition intensified. This explains why the market is valuing the stock at just 8 times forward earnings -- a price that implies its core cash flow provider is in structural decline.
The bleeding in its connectivity business, the company's largest and most profitable segment, is being driven in part by stiff competition from fixed wireless access offered by rivals like T-Mobile and Verizon (VZ 5.11%). Attrition not only continued last year but rose by 73%. More concerning, the subscriber losses accelerated as the year went on, with the fourth quarter's loss of 181,000 customers topping the third quarter's 104,000.

A strategic pivot with some near-term pain
In response to the decline, management has launched a multi-part strategy. First, it simplified the story by spinning off its legacy cable television networks in January into a stand-alone entity called Versant Media. What remains is the embattled broadband and wireless business, alongside NBC and Peacock, Universal theme parks, and a movie studio.
Second, it shifted operational strategy, offering promotions such as free wireless lines and five-year price guarantees. The goal is to curb customer broadband churn and drive adoption of its wireless service. This defensive move comes at a direct cost to the segment's EBITDA margins, which are now expected to face pressure through 2026.
While connectivity margins take a hit, the company's wireless segment remains a bright spot. Comcast runs this service on Verizon's network, which keeps its operating costs low. The company added 1.5 million net new wireless lines last year, bringing the total to 9.3 million. That represents around 15% of its broadband base, and management sees plenty of room to expand. Yet this growth is tied to the very base that is shrinking.
Within its content and experiences segment, the theme parks delivered strong results. Adjusted EBITDA grew 24%, surpassing $1 billion in a single quarter for the first time, fueled by the opening of Epic Universe in Orlando, which generated record revenue. This provides another layer of cash flow to help plug the holes.
The market's not convinced yet
Comcast returned cash to shareholders in 2025 through $6.8 billion in buybacks and $4.9 billion in dividends. Still, a 4.7% dividend yield and a valuation of just 8 times forward earnings show the market's focus remains on the long-term durability of the business. The investment case centers on whether these offsets from wireless and parks, which have natural ceilings, can outrun the structural and ongoing secular decline in broadband.

Key Data Points
The first real sign of the strategy's effectiveness will come with the second-half 2026 results, when the conversion rate of free wireless lines to paid plans is reported. A solid conversion rate would validate the margin trade-off and support long-term cash flows, while a disappointing one would signal that the pressure on profits is here to stay.
