Comcast Trades at Just 8 Times Earnings After Losing 711,000 Broadband Subs Last Year

Comcast’s core broadband business lost over 700,000 domestic customers, with Q4 attrition accelerating to 181,000 vs. 104,000 in Q3 as competition from fiber and fixed wireless intensified. Management is defending the base with promotions and free wireless lines, but that strategy is expected to दबress EBITDA margins through 2026 even as wireless lines rose 1.5 million to 9.3 million and theme parks delivered 24% adjusted EBITDA growth. The stock remains cheap at 8x forward earnings with a 4.7% dividend yield, but the market is skeptical that wireless and parks can offset structural broadband decline.

Analysis

The key second-order issue is that Comcast is not just trying to defend share; it is effectively buying time by monetizing its highest-quality customer relationships at lower margin. That can stabilize reported revenue while quietly degrading the economics of the connectivity stack, which matters because the market is likely capitalizing broadband as if it were a durable annuity rather than a shrinking, promotion-dependent utility. The real risk is that wireless attach becomes a defensive substitution product, not a growth engine, so each incremental save in broadband merely migrates value from a high-margin fixed line to a lower-margin resold mobile line.

The better short thesis is not near-term earnings miss risk, but a longer-duration multiple reset if conversion on promotional wireless fails to re-rate the “defensive pivot” by late 2026. If the free-line cohort monetizes poorly, Comcast will have traded margin for churn suppression with no lasting unit economics improvement, and that should compress both broadband and consolidated EBITDA expectations. Theme parks can cushion cash flow, but they are too episodic and capacity-constrained to offset a secular deterioration in the core franchise for long.

On the other side, the most plausible beneficiary is Verizon, but not through headline wireless share gains; rather, its network-hosting economics improve if Comcast’s MVNO growth increases wholesale traffic without forcing aggressive price competition. T-Mobile is the more exposed competitor because fixed wireless remains its strategic bridge into broadband share capture, and any evidence that Comcast’s promotions are reducing churn could imply slower FWA payback across the industry. The market may be underestimating that this is a margin war, not a subscriber war: whichever operator subsidizes acquisition the longest can win share, but everybody’s returns fall.

The contrarian setup is that the stock may already discount a lot of the bad news, so the catalyst path matters more than the narrative. A sharp upside in theme parks or wireless conversion could produce a short-covering rally, but absent that, the stock is likely to remain trapped in a low-multiple, high-yield value bucket until there is proof the broadband base has stopped bleeding on an organic basis.

Key Decisions for Investors

• Short CMCSA on a 3-6 month horizon if the market rallies into the low-teens earnings multiple; risk/reward favors downside because 2026 margin pressure can re-accelerate as promotional subsidies roll through the P&L.
• Pair trade: long VZ / short CMCSA for a defensive telecom expression; VZ has cleaner economics from Comcast’s wireless growth via wholesale traffic, while CMCSA bears the margin cost of customer retention.
• Avoid long TMUS on the basis of fixed wireless share gains until broadband churn stabilizes; if Comcast’s retention tactics work, FWA payback assumptions likely need to be revised lower over the next 2-4 quarters.
• For event-driven accounts, buy CMCSA puts or put spreads into the second-half 2026 conversion print; that is the first real catalyst where the market can distinguish between temporary subscriber stabilization and durable monetization.
