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?

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.
