Address, industry classification, listing and incorporation come from AT&T Inc.'s own SEC filer record, so the industry is the SEC's dry classification rather than a marketing label.

Select a row or a slice for its provenance: the filing it came from, when it was measured, and the arithmetic behind it if it was modelled.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 2,928 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

2,928 managers reported a position, together holding 4.59bn shares, or 66.0% of the company. The 40 largest are listed. Percentages are of the 6.95bn shares outstanding at 22 Apr 2026, the count in force when this quarter was measured rather than the count today.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.
