Know the Business
Cable One is a small, rural-focused cable broadband operator with attractive unit economics attached to a stressed equity. The owned coaxial/fiber plant generates roughly 53% Adjusted EBITDA margins on recurring subscription fees, but revenue is in a third year of decline as fiber overbuilders and 5G fixed-wireless arrive in the tertiary markets. $3.0B of net debt against a $275M market cap leaves the equity priced as an option on whether broadband net adds inflect before covenant headroom runs out. The market is treating this as a melting ice cube; the bull case is that the cable engine still throws off roughly $500M of Adjusted EBITDA-less-capex on which equity is valued at less than 1×.

1. How This Business Actually Works
Takeaway: Cable One owns a wired pipe into about 2.9 million homes and businesses, sells those subscribers a monthly internet bill at roughly $81 each, and earns most of its profit from that single line — residential data — because the marginal cost of delivering another gigabyte is effectively zero once the plant exists.
The engine has three moving parts. (1) Sunk capex builds and upgrades the hybrid fiber-coaxial / fiber plant; cumulative PP&E is $1.8B against $1.5B of annual revenue, and roughly 19% of every revenue dollar is reinvested. (2) Recurring monthly subscriptions on that plant produce the revenue — 75% of which is data (60% residential, 15% business). (3) The leftover after operating cost and capex services $3.2B of debt and, in good years, returns capital. The single most important fact about the cost structure: residential data has roughly three times the Adjusted EBITDA margin of residential video, and business data has roughly four times (per management's 10-K), because programming and retransmission fees consume 59–63% of every video dollar while data is mostly fixed cost.
The mismatch between where revenue comes from and where profit comes from is the central picture. Voice and video together are still 19% of revenue but are essentially gross-margin-negative once programming costs are netted. Cable One has explicitly chosen to let video bleed out rather than discount data to retain video subs — residential video PSUs fell 22.1% in 2025 and 20.0% in 2024, about 2× the industry pace. This is a deliberate margin trade.
The entire economic story is on one chart. About 53 cents of every revenue dollar reaches Adjusted EBITDA, capex eats 19 cents, cash interest takes 9 cents, and roughly 26 cents is left for the equity — except $356M of GAAP net loss in 2025 reflects $586M of non-cash franchise/goodwill impairment plus $138M of equity-method losses on minority stakes in fiber overbuilders. The underlying cable engine is intact; the impairment and the equity-stake losses are how the reported book is paying the price of the strategic bet on adjacent fiber.
The bargaining power picture is asymmetric in a useful way. Upstream, programmers have leverage (the reason video is unprofitable). But for residential data — 60% of revenue — there is no programmer to pay. Downstream, switching costs are real but not absolute: a customer can switch in 1-2 days. The defense is that in 40% of the footprint there is no wired competitor offering 100 Mbps, and in those census blocks Cable One is the only realistic broadband option.
2. The Playing Field
Takeaway: Cable One is the smallest of the public cable peer set, the most levered relative to size, and historically the highest-margin — a profile that depends entirely on its rural footprint remaining underbuilt. Of the five real comps, only Altice (ATUS) has been forced to the same end-of-cycle conversation, and ATUS now trades as a stressed equity.
Three things matter in the peer set. First, CABO has the highest Adjusted EBITDA margin in the group — 13 to 23 points above the cable majors and 15-23 points above the fiber peers — because the small-rural footprint avoided the cost-loaded urban operating model, the video business has been actively shrunk, and there is no NBCUniversal-style media segment diluting cable returns. Second, scale economics are weaker than the textbook suggests: Comcast and Charter are 80-150× CABO's size but earn lower segment margins, because the marginal customer in a major city is more expensive to acquire and serve, the video segment is harder to abandon, and programming leverage matters less than it used to. Third, CABO is the cheapest stock by a wide margin — 4.1× EV/Adjusted EBITDA versus 5.2-5.8× for the majors and 12-19× for the distressed names — the market's verdict that the operating margin and the leverage are about to collide. ATUS is what happens when the collision is not survived; SHEN's Glo Fiber is one of the businesses Cable One competes against; WOW is being taken private at a similar size because the public-equity market does not want to own this profile any more.
3. Is This Business Cyclical?
Takeaway: Not cyclical at the household level — people do not cancel home internet in a recession — but intensely cyclical at the competitive level, and Cable One is in the middle of its first sustained overbuild cycle since the spin-off. Revenue has fallen 12% from the 2022 peak and Adjusted EBITDA margin is 4 points off its 2022 high, not because demand fell but because the competitive landscape changed.
This is the cable cycle in microcosm. The 2019-2022 surge bundled COVID demand, the Hargray acquisition (May 2021), and across-the-board rate increases. The post-2022 rollover is the live overbuild — and crucially, the margin has held up much better than the revenue, because management has defended ARPU rather than chased subscribers with discounts, and let the lowest-margin video customers go fastest. Residential data ARPU was $80.84 in 2025 vs. $80.39 in 2024, essentially flat. The pain is in subscriber count, not unit pricing: residential data PSUs fell 5.8% in 2025 (-55,300 net), and Q1 2026 brought another sequential drop.
Two cycle facts not in the financials. First, the cycle hits operating metrics (gross adds, churn, ARPU) 12-24 months before reported revenue — so by the time revenue has rolled over, the operator is deep into the down-leg. Cable One is in year three; ATUS has been in decline for five years and is now distressed. Second, the cycle ends when the competitor's economics break, not the incumbent's — private fiber overbuilders are funded by patient capital with 5-10 year payback assumptions and only stop building when subsidies close or interest rates tighten the cost of overbuild capital. The current overbuild up-cycle started around 2021 and shows no sign of ending in 2026.
4. The Metrics That Actually Matter
Takeaway: Reported revenue, EPS, and EBITDA margin are lagging indicators. The leading set is five things — residential data net adds, residential data ARPU, Adjusted EBITDA less capex, net leverage, and the path of capex intensity — because they tell you 6-18 months in advance whether the cable engine is intact or breaking.
Two things the headline revenue decline obscures. First, Adjusted EBITDA less capex grew through the revenue decline — from $478M in 2022 to $517M in 2025 — because capex came down as the DOCSIS / fiber-deep upgrade wave passed. Second, capex/EBITDA is now around 36% versus the 46% peak in 2021 — mid-cycle on reinvestment, not pre-cycle. If competitive intensity forces a fresh DOCSIS 4.0 / fiber overbuild response, this metric returns to 45%+ and the cash story changes meaningfully.
The metric Cable One does not disclose quantitatively but matters most for the bear case is monthly residential data churn. Management has commented qualitatively that competitive churn rose in overbuilt markets, but no rate is published. A move from healthy 1.2-1.5% to 2%+ would imply ARPU has to fall to defend retention — and that is what breaks the model.
5. What Is This Business Worth?
Takeaway: Cable One is best underwritten as a single economic engine — the wholly-owned cable broadband network — valued on Adjusted EBITDA less capex, with the minority equity stakes in fiber overbuilders treated as an optional add-on that is currently a drag rather than a benefit. The market is paying roughly 4× EV/Adjusted EBITDA, less than 1× equity value to Adjusted-EBITDA-less-capex, and is therefore valuing the equity as if the cable cash flow keeps falling at 5%+ per year indefinitely.
The valuation lens that fits is EV / Adjusted EBITDA-less-capex, not P/E and not EV/Revenue. P/E is meaningless because of impairments and equity-method volatility. EV/Revenue is meaningless because the mix is shifting toward data and away from video, which doubles or triples the margin per revenue dollar. Adjusted-EBITDA-less-capex is what services the debt, funds the equity, and is what cable management teams are compensated against.
A sum-of-the-parts lens is only partly helpful here: the equity-method investments (Clearwave Fiber, Point Broadband, Nextlink, MBI) are real assets with real carrying values, but they have produced four straight years of losses, two material impairments, and divestitures in 2025 (Ziply, MetroNet sold). Treat them as upside optionality at carrying value (~$249M, less than the market cap), not as meaningful contribution to going-concern value. The MBI buyout — Put exercised January 2026, closing October 2026 — is a balance sheet event: it converts a 45% economic stake into 100% ownership and adds MBI's revenue (~$240M), EBITDA, and debt to the consolidated entity. Neither cleanly accretive nor dilutive on day one; the post-close consolidated leverage profile is the thing to model.
The single fact that matters most for valuation: at $275M market cap, the equity is being valued at 0.53× FY2025 Adjusted-EBITDA-less-capex. For comparison, healthy cable peers trade at 5-8× this metric. The implied market view is either (a) Adjusted EBITDA-less-capex collapses by more than 50% over the next 3-5 years, or (b) covenant breach forces equity dilution or restructuring before that cash reaches shareholders. The bull case is that neither happens; the bear case is that one or both do.
6. What I'd Tell a Young Analyst
Takeaway: This is a cigar-butt setup with a real asset and real leverage. Forget the GAAP loss; the question is whether the cable engine's cash earnings stabilize before refinancing pressure forces the equity into a bad outcome. Watch four things and ignore most of the rest.
Watch broadband net adds quarterly, not annually. Residential data PSU change is the number that moves the stock most. -55,300 in FY2025 is the bear case proven; a return to roughly flat for two consecutive quarters is the bull case proven. Industry-wide, every public cable operator except small fiber pure-plays lost residential broadband subscribers in Q1 2026 — the first time in the modern history of US cable. Watch whether CABO loses fewer than CHTR/CMCSA on a percentage basis; that would mean its rural moat is holding.
Watch the back book, not the front book. ARPU was $80.84 in 2025 vs. $80.39 in 2024 — barely changed. The bear case is that retention discounts spread from the front book (acquisitions) to the back book (existing customers), which is invisible in ARPU until it suddenly appears as a 2-3% drop. Sequential quarterly ARPU is the leading indicator.
Treat MBI close as the next pivot. The MBI Put exercised January 2, 2026, closing no later than October 1, 2026. Post-close, Cable One owns 100% of MBI, adds roughly $240M revenue and $100M+ Adjusted EBITDA to consolidated results, takes on the debt, and loses the optical illusion of equity-method losses on a 45% stake. The acquired EBITDA helps the leverage ratio; the additional debt offsets some of it. Build the pro-forma now.
Treat the equity stakes as optional, not core. The Clearwave Fiber contribution to Point Broadband (closing Q2 2026), prior monetizations of Ziply and MetroNet, and the running impairments on remaining stakes tell you management is harvesting these positions rather than building them. Value them at carrying value, not at a strategic premium.
What would change the thesis. Bullish: two consecutive quarters of stable-to-positive residential data net adds, debt paydown above $300M/yr, and Adjusted EBITDA-less-capex holding above $500M. Bearish: ARPU declines sequentially for two consecutive quarters, Adjusted EBITDA margin falls below 50%, or material BEAD overbuild awards land in the seven core states. The new CEO (Jim Holanda, February 2026, formerly Astound Broadband CEO 2011-2025) spent his career running a private fiber overbuilder — exactly the kind of competitor that has been pressuring Cable One. Whether he can stabilize what he previously helped disrupt is the most under-priced question on the equity.
The cleanest mental model: Cable One has a real $500M-ish annual cash earnings stream attached to $3B of debt, trading at $275M of equity. If the cash stream holds, the equity is mispriced by a wide margin. If the cash stream falls 30%, the equity may be uninvestable. The market is voting for the second outcome; the question is whether it is wrong.
