Is Comcast Stock Cheap Or Just Shrinking?
Comcast (CMCSA) generated free cash over the past twelve months worth 20.1% of its market value. The median S&P 500 company manages 4.4%. Part of that gap is Comcast’s debt. The rest means one of two things: the market has made a mistake, or the cash is about to get smaller. Comcast keeps losing broadband customers, and that is the market’s answer.
Where Does Comcast’s Cash Actually Come From?
A wire into the home, and a phone bill that rides on it. Comcast bills a monthly broadband subscription over a network it already built. Xfinity Mobile sells phone lines without owning a mobile network, renting capacity through MVNO deals. Management says about 90% of that mobile traffic is offloaded onto Comcast’s own WiFi, which holds the cost of a line down.
The cash is real. Free cash flow over the past twelve months was $17.82 billion on $124.91 billion of revenue, and it has been positive in every rolling twelve-month period for three years.
Not all of it is yours. Net debt is about $82.7 billion, nearly as large as the $88.7 billion market value, and it gets paid first. Measured against enterprise value instead, the same cash is a yield of about 10.4%. The difference is the debt, and 10.4% is the figure the case rests on.
Why Is The Market Betting The Cash Shrinks?
Because the wire is losing customers. Comcast lost 167,000 broadband subscribers in the second quarter of 2026. Broadband ARPU fell 3.8%, and EBITDA in the Connectivity & Platforms segment fell 5.8%, both year-over-year.
Some of that is a choice. Comcast did not take a broadband rate increase, moved customers onto lower everyday price points, and handed out free wireless lines that dilute broadband ARPU. The competition is not. Fiber keeps expanding, fixed wireless stays aggressive, satellite is emerging, and management says it assumes the market stays intensely competitive.
Cash generated is also not cash paid out. Dividends and buybacks returned about 11.8% of market value over the past twelve months, but Comcast paused the buyback on July 1, 2026, and expects it to stay paused until the company splits in two.
Can Comcast Stop Losing Broadband Customers?
Not yet, but the losses are narrowing. The second-quarter loss was 34,000 smaller than the same quarter a year earlier. Xfinity Mobile added a record 448,000 lines in the second quarter of 2026 and crossed 10 million, which management puts at 17% of its domestic residential broadband customers and only 7% of the lines its footprint could serve. Peacock turned EBITDA positive for the first time, $189 million in the quarter.
Not everything is mending. In July, management said attendance across the broader Orlando market softened in June and had stayed soft into the third quarter of 2026, even as Epic Universe keeps drawing the guest response Comcast expected.
The number that settles this is broadband subscribers in the third quarter of 2026. Narrow the losses again while wireless scales and the cash holds. Widen them, and you are buying a business in retreat.
