# Comcast Monitoring Guide






## What Did COMCAST CORP Last Report?

These are the starting values for the dashboard below, as COMCAST CORP reported them for the fiscal year ended December 31, 2025 and the year before. At the next filing, compare each current value with these and write down the direction before reading management's explanation.

| Reported measure | FY2025 | FY2024 | Change |
| --- | --- | --- | --- |
| Revenue | $124 billion | $124 billion | -0.0% |
| Operating margin | 16.7% | 18.8% | -2.1 points |
| Net margin | 16.2% | 13.1% | +3.1 points |
| Free cash flow | $21.9 billion | $15.5 billion | +41.3% |

Free cash flow is operating cash flow minus capital expenditures. A change in a margin is stated in percentage points, so a margin moving from 20.0% to 23.0% is a gain of 3.0 points. "Not reported" or "n/a" means the company filed no value under the standard tag, not that the amount was zero.

- Wireless line net additions
- Peacock paid subscribers
- Domestic advertising revenue
- Theme parks revenue
- Adjusted EBITDA
- Capital expenditures
- Free cash flow
- Net leverage
- Share repurchases








## Before earnings or a filing



Review the prior quarter's expectations, unresolved questions, and thesis breakers. Record what you expect to learn from the next filing without predicting a stock-price reaction. This prevents hindsight from rewriting the original thesis.








## After the filing



Start with reported statements, notes, and reconciliations. Update the dashboard, then read management discussion. Separate changes caused by volume, price, mix, currency, acquisitions, accounting, and one-time items. Reconcile cash flow and share count, not just earnings per share.








## Competitive check



Compare relevant evidence with **AT&T, Alphabet Inc., AppLovin, Charter Communications, EchoStar, Fox Corporation**. Determine whether a trend is company-specific or industry-wide. Use comparable definitions and periods.








## Macro check



Review advertising spending, consumer discretionary spending, broadband and wireless demand, interest rates, media consumption trends, regulatory policy. Only elevate a macro variable when there is a defensible channel into Comcast's demand, pricing, costs, financing, or asset values.








## Change log



Maintain a dated log with four labels: **fact**, **interpretation**, **scenario**, and **unknown**. Link every time-sensitive factual change to a primary source. If a prior assumption is wrong, preserve the old entry and explain the revision rather than silently rewriting history.
