Charter Communications, Inc. CHTR

Key data

The business

Charter sells broadband internet, video, and mobile under the Spectrum brand, running one of the largest cable networks in the US. The money is overwhelmingly broadband: high-margin internet subscriptions over lines already in the ground, with video a shrinking low-margin drag and mobile the newest leg, resold over Verizon's network and bundled to hold customers in. The moat is the physical plant, a network that would cost tens of billions and years of permitting to rebuild, plus the pricing power of being the only fast option on many streets. That last part is eroding: T-Mobile and Verizon now sell home internet over wireless spectrum, and fiber overbuilders are digging into Charter's footprint. The August 20, 2026 agreement to absorb Cox Communications and fold in Liberty Broadband is the company's answer, scale to defend the wire.

The numbers

The equity story splits cleanly from the operating story. Start with the quarters.

Revenue has declined every quarter shown, a slow bleed from $13.77B to $13.53B, while net income held roughly flat near $1.3B. Earnings per share climbed to $10.66 in Q2 2026, up 16% year over year, beating the $9.98 consensus. The gap between flat profit and rising per-share earnings is the entire Charter thesis in one line: buybacks, not growth.

Between 2021 and 2025 net income barely moved, $4.65B to $4.99B, yet EPS climbed from $24.47 to $36.21. The entire gain came from the share count, which Charter shrank about 27% by spending roughly $35B on its own stock over five years. That engine is now idling: A/N, the Newhouse partnership, suspended its buyback participation on August 4, 2025 ahead of the Cox deal. The uncomfortable detail is price paid: the biggest repurchases, $15.4B in 2021, retired stock north of $600 a share, four times today's $152.

The market prices this as a melting ice cube, the lowest EV/EBITDA in its history. The print that settles whether that is right is 2027 capital spending: if it rolls off below $10B as the network upgrade finishes while revenue holds, the free cash flow against a $20.5B equity base is enormous; if capex stays high while the top line erodes, the leverage is the story.

Management

The record is mixed and worth reading closely. Insiders sold about $12.7M and bought $3.8M over the past year, but composition matters more than the net: the largest seller, Thomas Rutledge, accounted for nearly all the outflow with $11.4M across late May, plan status not disclosed, while director Mauricio Ramos put $1.4M of his own money in on the open market in mid-May, the only move that reads as conviction. Pay is tied heavily to buybacks and per-share metrics, which is precisely why management kept retiring stock at prices it now looks foolish to have paid. The guidance record is steadier: Charter beat on earnings in two of the last four quarters, including a clean $10.66 against $9.98 in Q2.

How it fails or surprises you

Broadband erosion accelerates. Revenue has fallen five quarters straight, down 1.7% year over year in Q2 2026. Fixed-wireless from T-Mobile and Verizon plus fiber overbuilders are taking the marginal customer. If the decline steepens past 3%, EBITDA follows and 4.8x net-debt-to-EBITDA stops being background and becomes the whole equity story. Watch quarterly broadband net losses and revenue trend.

Capex rolls off and free cash inflects (right tail). Charter has spent more than $50B upgrading its network since 2021, capex peaking near $11.7B. As the buildout finishes, that spend should fall while the plant keeps earning. Against a $20.5B equity base throwing off about a 21% free-cash yield, even a modest capex drop makes the stock look mispriced. Watch the 2027 capital guide.

The buyback engine stays dark. Every dollar of EPS growth since 2021 came from a shrinking share count, and A/N suspended its buyback on August 4, 2025. If repurchases stay paused through Cox integration while revenue erodes, the one visible tailwind is gone. Two days on, no combined-entity leverage figure or capex guide has printed to change that, only bondholder change-of-control mechanics on the Cox financing. Watch the repurchase line each quarter.

Closing thoughts

Two prints settle most of the uncertainty: the Cox close and the 2027 capital-spending guide together tell you whether free cash flow surges or broadband erosion compounds first. The debt itself, $94B against a $20.5B equity base, never becomes safe; it is always there, but those two numbers tell you whether Charter earns enough through it or drowns under it. The left tail is an accelerating broadband decline that turns the leverage into a trap, and it is fatter than the 3.9x multiple suggests. The right tail, a post-buildout free-cash surge on that $20.5B base, is worth multiples of today's price. The odds sit closer to even than the price implies, which is judgment, not arithmetic.

The bet is still that Charter's wire carrying internet service to its customers stays valuable and the customers who stay keep paying, enough to service the debt and eventually free the cash the network throws off. What breaks it is simple: broadband revenue turning down faster than capex falls. The one pair of numbers that tells you first is quarterly revenue growth against the capital-spending guide. If capex has not fallen below $10B in 2027 while the top line keeps eroding, the cheapness was a trap and the debt was the spring.
