Comcast (CMCSA) Stock Jumps As Q3 Earnings Counter Broadband Pressure

Comcast stock jumped 3.4% to US$22.84 in Thursday trading, a brisk move for a mature cable and media giant that has spent the past year grinding through margin pressure and a complex breakup plan. The trigger was Q3 2026 earnings, with adjusted earnings per share of US$1.07 and free cash flow of US$4.2b giving investors a cleaner look at performance without the noise of past one offs.

Short term traders are reacting to the pop. Longer term holders are weighing something different: a business with a 7.2x trailing P/E, a 5.78% dividend yield and a large separation of NBCUniversal and Sky on the horizon.

Comcast Bull Case: Early Proof Points, Not Victory

Bulls argue Comcast can turn convergence, streaming and parks into durable earnings growth. The ambition is clear.

"The main thing that has to go right is that connectivity pivots, wireless free line conversions, Peacock’s dual revenue model, parks expansion, and the NBCUniversal spin off all translate into durable EBITDA growth, despite current ARPU pressure, softer park profitability, and reduced analyst targets."

Q3 offers mixed evidence. Connectivity revenue and EBITDA both declined, so that pillar has not yet turned. Wireless looks closer to plan, with 368k net line adds and management citing roughly 70% conversion from free to paid. Media leans into the thesis, with Peacock profitable again and Media EBITDA rising. Parks clearly miss the mark, with revenue and EBITDA both weaker.

Comcast Bear Case: Broadband Pressure Still Bites

The cautious view hangs on broadband unit economics staying weak as convergence grows.

"Although Comcast is building a larger base of converged broadband and wireless customers with 10.2 million wireless lines and meaningful runway left in its footprint, the recent 3.8% decline in broadband ARPU and reliance on simplified, lower everyday pricing and initially dilutive free lines point to a risk that future convergence growth is achieved at weaker unit economics, which could cap revenue per household and limit earnings growth from Connectivity & Platforms."

Q3 results lean toward that concern. Connectivity & Platforms revenue fell 2.6% and EBITDA declined 4.4%, with broadband net losses of 144k offset by 368k wireless line adds. Convergence revenue edged lower and convergence ARPA slipped 0.5%. Comcast is converting free lines and boosting gig+ adoption, yet this quarter does not show these moves lifting earnings in connectivity enough to blunt pricing and churn pressure.

Hunt For Quiet Dislocations

Comcast just showed how a single quarter can reshape the debate around a mature business. The real opportunity could be in stocks where fundamentals and expectations have not yet lined up.

• Company 1 - 23% below our estimate - builds high-capacity manufacturing and distribution for cardiometabolic and obesity incretin therapies.
• Company 2 - 41% below our estimate - expands a device trade-in and recommerce network shaped by subsidies and refurbished demand.
• Company 3 - 35% below our estimate - grows advisory fee income across capital markets, private capital and restructuring mandates.

Those are three of them. See the full list of 30 companies trading below our fair value estimates →
