CMCSANASDAQThe short version
Comcast Corporation
Comcast is an $83B US broadband, media and theme-park operator whose stock has halved since late 2024 as cable loses internet subscribers to fiber and 5G home wireless. This is a framework-fit test, not investment advice.
From a $45.14 peak in November 2024, the shares fell 51% to a $21.92 low in July 2026 as broadband subscriber losses mounted.

- Two businesses. Connectivity & Platforms — Xfinity broadband, wireless and video — booked $81B at a ~40% margin; NBCUniversal media and Universal theme parks added $38B at ~9%.
- Cash is steady. Reported free cash flow has been positive every year for a decade, ranging $10.6B to $21.9B, with FY2025 the high on a one-off low cash-tax year.
- Fewer shares. Buybacks cut the count from 4,875M in 2016 to 3,709M in 2025 — but repurchases are paused from July 2026 through a planned corporate split.

Framework reference lines, not scores or grades.
- The gate decides it. Comcast clears both universe screens and trips no exclusion, but the year-10 durability gate is binary — any real doubt fails it — and residential broadband, the profit core, is losing subscribers to fiber and 5G home wireless. Four jury seats agreed; probability 0.445.
- The strong counter-fact. The entry case is real: a 51% drawdown, an adjusted FCF yield near 19% against a 10% bar, and a 24% share-count cut. Those clear the framework's lines — but none of them offsets a failed gate.
- One split call. The buyback engine (P4b) is contested 2–2: executed hard for a decade, yet paused July 1, 2026 through the separation — non-load-bearing, so it does not move the gated result.
What Comcast is
A capital-heavy broadband network with a media and parks business bolted on
FY2025 revenue by segment ($B)
Connectivity & Platforms$81.1B68%
Content & Experiences$38.1B32%
Connectivity is ~90% of segment profit; the rest is NBCUniversal media and Universal parks.
- The network is the business. Connectivity & Platforms owns the last-mile plant, passes ~65 million homes and sells internet as the anchor of a bundle — about 90% of segment profit at a ~40% margin.
- Mostly domestic and essential. The US supplies 77% of revenue, the UK 12%. Broadband is the anchor product and the profit engine that the year-10 durability question turns on.
The dislocation
A 51% fall over 20 months, in two clustered legs a year apart
Daily close, Nov-2024 peak to Jul-2026 trough.
- Two triggers, not a miss. Comcast beat EPS every quarter of the decline. What repriced was broadband: −711k subscribers in FY2025, then the ARPU and margin cost of defending the base through 2026.
- Modest capitulation. Peak volume ran 2.5x the pre-peak median — above the 2x reference line but far from true panic — and the 51% depth stops short of the 60–70% forced-selling zone the framework prizes.

Market cap from the peak

FCF yield the market demands
- A third cut, two-thirds re-rating. Holding the peak multiple, the ~20% forward-FCF cut explains about $35B of the $94B drop. The other ~$59B is the market re-rating the yield from 9.6% to 16.5%.
- Whether that is fair depends on the diagnosis. A conservative permanent reset destroys ~$47B of value; a temporary one only ~$8B. Which it is decides the whole tab — and the trial's answer follows.
Diagnosis
Temporary transition or durable reset — the trial leaned durable
NPV damage vs price damage ($B)
FCFE perpetuity vs the $94B market-cap loss.
- The ruling. Two cited briefs, three blind judges: the probability the impairment is temporary came in at 0.38, below the 0.65 a fit would need — leaning toward a durable reset.
- Both sides are real. For temporary: Q2 2026 losses narrowed 34k, wireless hit a record, Peacock turned its first profit. For permanent: price and volume are falling together and video keeps draining. The gap only pays in the minority branch.

14%
- Above the line every way. On the framework's basis — FCF less stock comp less average deal spend — Comcast earned ~$20B in FY2025, a 24% yield; the 3-year average of 19% still sits ~940 bps over the bar.
- The honest discount. FY2025 is flattered by a low cash-tax year ($0.8B paid versus $7.1B). Normalized, the yield is nearer 15–17% — lower, but still well clear of 10%.
Year-10 durability
The profit core is losing subscribers, and price is the only offset
Domestic broadband vs video customers (M)
- Losses are accelerating. Broadband net losses ran −66k, −411k, then −711k across FY2023–FY2025 as fiber overbuild and 5G home internet took share; T-Mobile alone targets 18–19M broadband lines by 2030.
- The cash leg holds; the revenue leg doesn't. Broadband revenue still rose on price, so FCF is defensible — but pricing is a finite offset against a shrinking base, and that is the doubt the binary gate refuses to wave through.
Self-help
A 24% share-count cut — with the engine now switched off
Shares outstanding (M)
- Executed, not just authorized. About $62.7B of buybacks over 2016–2025 took the count from 4,875M to 3,709M, net of dilution — the opposite of the framework's rising-share-count fail.
- Idle when it matters most. Repurchases paused July 1, 2026 through the ~one-year separation, with $8.9B authorized and unused — the flywheel off exactly when a mid-teens yield would make it most valuable.
Balance sheet
It can fund its own rescue without a forced choice
Fixed-rate debt maturities ($B)
$98.9B total debt at a 4.0% average rate, mostly long-dated.
- Room to outlast the problem. Roughly $5B of maturities a year sit against $20B+ of free cash flow, $9.5B of cash and an undrawn $11.8B revolver; leverage is 2.4x, inside the framework's moderate band.
- No forced deleveraging. Debt is mostly fixed and stretched past ten years, so capital allocation is not pushed toward paydown — buybacks and a well-covered dividend are affordable alongside it.
The clock
Re-rating needs operational repair, and the fastest lever is off
What has to happen, and roughly when
| Catalyst | Window | What it signals |
|---|---|---|
| Q3 2026 print | Oct 29 2026 | Broadband loss-rate; free-line conversion |
| Free-line conversion | H2 2026 | Paid conversions lift convergence revenue |
| Q4 2026 print | late Jan 2027 | First full anniversary of the repricing |
| NBCUniversal split | ~mid-2027 | Sum-of-the-parts unlock; buyback pause ends |
| Buyback resumption | post-split | Share count resumes shrinking |
- Repair, not a reset. The gap closes only if broadband losses flatten and free wireless lines convert to paid — testable at the Q4 2026 and 2027 prints — with the NBCUniversal split as the structural catalyst near mid-2027.
- Optionality exists, cheaply. Listed CMCSA options run to January 2028, about 18 months out, near 31% implied volatility — inside the reference band, stated as a dated web-sourced fact, not advice.
The path back
Consensus sees cash flow troughing in 2027, back to 2025 only by 2028–2029
Consensus free cash flow path ($B)
- No 18-month precedent. The only comparably deep fall in Comcast's history (1999–2009, −68%) took years to repair; the shallow 2018 and 2020 dips were half as deep. A full re-rating inside 18 months has no precedent here.
- What the framework concludes. The dislocation, yield and self-help pillars are genuinely strong, but the year-10 durability gate does not hold — and by construction that gate settles the result.
What to watch
Cheap, cash-rich and shrinking its share count — but the year-10 durability gate does not hold
- 01Domestic broadband net adds turn positive without further ARPU decline across multiple quarters post-lap
- 02Broadband net losses re-accelerate past ~200k/quarter after the 2026 lap
- 03revenue declines for a third consecutive year
- 04share count inflects upward
This distills a fixed, tab-by-tab fit test — measured against the framework's own reference lines, not investment advice.
