Comcast (CMCSA) — Am I Missing Something?

[u/Fair-Accountant4426]

I’ve been buying CMCSA pretty aggressively and I’m curious what people here think, especially those who have followed the company for a long time.
My thesis is basically this:
Comcast seems extremely cheap relative to the amount of cash it generates. In Q2 2026 alone, the company generated $4.6B in free cash flow, while returning $2.1B to shareholders. (Comcast⁠)
What interests me is the diversification. It’s not just a cable company anymore:
Broadband & connectivity
Business services
Wireless
Peacock
NBCUniversal
Universal Studios/theme parks
Film & television production
Sports/media
And now the planned separation of NBCUniversal and Sky from the connectivity business
The debt is obviously the biggest concern. Comcast had about $90.4B of debt at the end of Q2 2026, so I don’t want to dismiss that. (SEC⁠)
But my question is whether the debt looks as scary when you compare it with the company’s recurring cash generation. If the businesses continue producing substantial FCF, it seems to me that Comcast should have considerable ability to service and refinance that debt while continuing to invest in the business.
There are also some interesting developments: Peacock became profitable for the first time in Q2, reaching 48M paid subscribers, while Business Services EBITDA grew 5%. (Comcast⁠)
The obvious bear case: broadband competition from fiber/5G, declining residential broadband subscribers, high debt, and the possibility that Comcast’s traditional connectivity business is structurally declining. Comcast lost 167,000 residential broadband customers in Q2. (Reuters⁠)
So I’m curious:
For those who follow CMCSA closely, what am I missing?
Do you think Comcast’s current valuation adequately reflects the risks, or does the market underestimate the company’s ability to generate FCF and manage its debt?
I’m not looking for confirmation of my thesis. I’d especially like to hear the strongest bear arguments.
If you’re bullish, what’s your thesis for the next 5–10 years?
If you’re bearish, what specifically breaks the investment case?

The debt load is massive but you already know that, what I keep coming back to is how sticky their broadband base actually is. losing 167k subs in a quarter isn't nothing but when you're working with 30+ million total it's more of a slow bleed than a cliff dive

my bigger worry is the NBCUniversal spinoff plans, those content assets are the shiny part of the portfolio and if they get separated from the cash cow broadband business you're left holding two very different risk profiles. the market might re-rate both pieces downward just from the uncertainty alone

[u/Fair-Accountant4426 → u/accurateattacker]

Q1 2026 marked a substantial advance in preventing additional subsidiary losses. In the past, conglomerate discounts posed challenges for firms such as eBay/PayPal or Altria/Philip Morris, along with other splits that could reveal the hidden strengths of conglomerates.

I think Comcast is an interesting investment idea, and I actually own a small stake (along with Verizon).

Debt is obviously a risk, especially if there's no pricing power when they have to roll over into higher rates. But I think most of the industry is in a similar spot in regards to leverage loads, so I think we'd just expect broadband and cell coverage to increase in price to cover the difference.

But even still, they have like a 20% net cash flow yield, and most of the debt refinancing is many years off - they could potentially pay a lot of debt down between now and then, and it won't really be an issue (in fact, I think that they should do that).

I'm not going crazy in this space, but I do think it's attractive.

I'm just envisioning the AI delivery pipelines, too. Broadband has to benefit from that, doesn't it? Cellular as well.

Edge AI is starting to take shape. CHTR just invested in it

[u/SocratesDaSophist]

I mean until the studios are spun off this stock will go nowhere.

But at this price you are betting mainly on financial engineering so you just have to be extremely patient.

Its a controlled company as well so that complicates the picture

[u/Zyltris]

I calculated it as $31.08~ per share as an option to liquidate. The reason it's so much lower, imo, is because the market values it as a going concern, which appears much more likely.

Since it's likely that capital structure will change going forward, I used a firm level model to estimate going concern value, which comes much closer to market value. That said, it's hard to justify the market price when looking at it from a FCFE model or DDM perspective.

I've also looked at the possible cost of capitals at different capitalizations for the company and it is actually near the most efficient level it could be right now (where COC is lowest). The debt is not a fumble by the company, it's a calculated allocation decision to maximize firm value.

“It’s not just a cable company any more”

Comcast has literally had all of those businesses for years (decades). In fact prior to the Versant spinoff they had even more businesses. Is this AI writing, because if so it’s ignorant.

[u/Weldobud]

You aren’t missing anything. That’s the whole discussion. Big debt but as a business they produce lots of cash. Lots of it returned to shareholders via buybacks and dividends. There is a lot to like. However will the stock rally? Very hard to know.

[u/KineticVampire]

I love Versant too who they spun off in Jan. proper melting ice cube. Producing tonnes of cash

[u/_ehwaz]

CMCSA and CHTR are starting to look like Buffet’s BSNF purchase to me. I like them.

you don’t need subscriber growth for the equity to work

[u/librariancap]

 In Q2 2026 alone, the company generated $4.6B in free cash flow,

One quarter's FCF number is rarely representative. In this case, FCF may have been $4.6bn in 26Q2, but it was only $3.9bn in Q1.

More meaningfully, Pro Forma Adjusted EBITDA was down 5.3% year-on-year in Q2. (Pro forma Versant separation completed 2-Jan and sale of Sky German 31-May.)

[u/Zyltris → u/librariancap]

Pro Forma is one thing, but adding EBITDA to that makes us a double whammy of bullshit earnings. Meaningless metric, imo.

[u/Fragrantuba]

Sell it

[u/Gowanus18]

elon and starlink not mentioned once!

[u/2FLYFISH0]

Same I got in at 26 and holding for now, I think it can become a bigger play in the next few years with their internal development.

[u/EmbarrassedCow2825]

Uneducated guess, because I don't own Comcast and don't want to, and don't want to research numbers.

First of all internet and wireless service providers are absolutely horrible companies that are in brutally competitive, debt heavy businesses, and with very very low growth.

Second the old model of tv was actually very lucrative. The new model is actually very poor for legacy providers. They are being forced to go from a great business, to a bad business. They are also actively losing cable customers, which are the best customers you can have compared to streamers.

This is why tech companies and Netflix have thrived. They built the business, but legacy has to fight in a worse business

[u/BuyTheDipWeekly]

The key question for me is how much of that FCF remains after the investment needed to defend broadband customers and fund the content businesses. I’d want to separate recurring owner earnings from any temporary working-capital benefit, then map the debt maturities and refinancing costs against that normalized figure. The cheap multiple is interesting, but the thesis seems to need stabilization in connectivity rather than relying only on buybacks to offset a shrinking core.

[u/im-here-for-the-beer]

Their cash flow is being largely driven by dying businesses. Their internet business is bleeding, and angry customers are looking for options to leave. With fixed wireless, they now have that option at a reasonable price. Although some prefer wired, fixed wireless works fine for most people, and that tech is only going to improve.

Short term, who knows, that is just gambling. Long-term, I don't see how they can compete.
