13F percentages divide the shares each institution reports by the Class A shares outstanding on the cover of the company's latest report before the quarter end (Apr 15, 2026). Entities of the same group file separately and are not added up. With more than one share class, a 13D or 13G counts shares convertible from another class as owned, so we do not show its percentage. We hold 13D and 13G filings made since Dec 23, 2024: a holder above 5% that has not filed since then does not appear here.

Comcast revenue

Comcast reported annual revenue of $123.71 billion for fiscal year 2025 (year ended December 31, 2025), according to its Form 10-K filed with the SEC (XBRL data).

Quarter flow (concentrated managers)

Change in managers (26 → 28): 3 opened · 1 exited = +2

Net flow in the quarter: −$793M (−32.3 M shares) · bought $128M and sold $921MShares concentrated managers added minus those they cut, valued at the 13F quarter-end implied price, not each trade's price. It is a different measure from the change in managers: the two can have opposite signs.

The set of concentrated managers changed between quarters: with the set as it was then, 27 held it last quarter (the chart point); with today's set, 26 (the base for the change).

From the figures the company filed with the SEC. Cash flow over net income near or above 1 means earnings are collected in cash; far below, that part is accounting. Coverage says how many times operating income pays the latest fiscal year's interest. Maturities come from the debt note of the latest annual report, counted from its closing date. “No data” never means zero.
