What COMCAST CORP reports

Revenue and net income below are for fiscal period FY2025, the period label carried by this company’s own annual XBRL filings to the SEC. Fiscal years do not line up between companies — one company’s FY2026 can cover much the same months as another’s FY2025 — so compare the periods, not just the numbers.

Revenue
$123.71B
FY2025 annual revenue, from this company’s own annual XBRL filings to the SEC
Net income
$20.00B
FY2025 profit for the period, from this company’s own annual XBRL filings to the SEC
Employees

Yahoo Finance
Where the employee count comes from

Headcount comes from Yahoo Finance, not from a filing. The date beside it is the day we retrieved the figure — it is not the date the company counted its staff, and Yahoo does not publish that date. Unlike the SEC filings behind the other figures on this page, this one carries no open licence, so we publish the number and nothing else from that source.

Insiders at COMCAST CORP

Shares is what each person last reported holding here.

Everyone below has filed at least one insider report against this company.

Value is that share count priced at the same closing price used everywhere else on this site. A row priced from only some of a person’s securities says so — we do not quietly present a partial sum as a complete one.

Rows are grouped by the role each person reports.

The role comes from the relationship boxes a person ticks on their own insider filings — officer, director, ten per cent owner — not from anything we infer. Somebody who is both an officer and a director appears once, in the combined group, so the row count still matches the figure at the top of this page. Where no filing states a role we say so instead of guessing one.

Recent insider transactions

Of the 213 rows we hold, 0 are open-market purchases and 10 open-market sales (S) — the only codes we count as buying or selling.

The rest — awards, shares withheld to pay tax, option exercises, gifts and so on — follow from an employment contract or a transfer arranged off-market, not from a decision to buy or sell, so counting them would turn this into a pay table.

A price of 0.00 is a real reported figure on gifts (G) and share awards (A) — not a gap in our data.

What a Form 4 is

The report an officer, director or large shareholder must file after trading their own company’s stock.

Corporate ownership links — what this company owns

Corporate ownership links for COMCAST CORP

What COMCAST CORP owns

This company files as an owner of the companies below.

A name in plain text is the end of the trail: we hold the filing that names it, but no separate record to open.

COMCAST CORP
Being named on an ownership form is not the same as legal parent–subsidiary control.

That relationship only holds if the filing says so. The map draws at most eight holdings per level, stops after two levels, and never doubles back on a name it has already passed through.

See the full ownership map — every entity that files as an owner of a US public company.

Subsidiaries — 1,495 legal entities

Subsidiaries of COMCAST CORP

1,495 legal entities named in the subsidiary exhibit filed with this company’s most recent 10-K. The table below shows the first 500 in alphabetical order. . Filing on SEC.gov.

This is not the full list. SEC rules only require a company to name its significant subsidiaries.

What that leaves out

Smaller entities are left out of the exhibit entirely. A short list here means a short exhibit — it does not mean the company owns nothing else. Nothing on this page is inferred: every name below is copied from the filing.

What counts as a subsidiary

A subsidiary is a separate legal entity this company controls; it is not the same thing as a brand, a division or an office. These entities do not file with the SEC in their own right, so there is no separate page to open for them.

Think a number here is wrong? Open the linked filing and compare — how to report it.

Sources and technical notes

Every figure on this page comes from filings to the U.S. SEC via EDGAR. Nothing here is estimated, and nothing is taken from press coverage or company websites.

Share count: weighted average over the reporting period (us-gaap:WeightedAverageNumberOfSharesOutstandingBasic), taken from COMCAST CORP’s own filings and multiplied by our closing price. ≈ Not a single-day figure — treat this market cap and its rank as approximate. Full method.

What that share count means

this company did not tag a cover-page share count we could read, so the figure is the average number of shares outstanding across the whole reporting period rather than a count on any single day. If the company issued or bought back stock during the period, the true count today is higher or lower than this.

We do not take a market cap from a data vendor, and we do not estimate one: the figure is a share count from COMCAST CORP’s own SEC filings multiplied by the closing price we hold for the same stock.
