Questions about who owns Tetra Technologies Inc.
Who owns Tetra Technologies Inc.?
On this page, one holder's latest ownership filing reports 5% or more of Tetra Technologies Inc.: Blackrock, Inc. (7.6%, Schedule 13G/A, filed 2025-10-17).
When did Blackrock, Inc. buy into Tetra Technologies Inc.?
The filings give report dates, not purchase dates. The earliest filing from Blackrock, Inc. on this page is the Schedule 13G/A, filed 2025-10-17, reporting 7.6%. That earliest filing is itself an amendment, which updates an earlier report.
Is this an audit or a full list?
Neither. The ownership list on this page covers only Schedule 13D and 13G filings, which holders make once they own 5% or more of a class of shares (an amendment can report a stake that has since fallen below 5%); 6 such filings are shown here. It is not an audit and not a full cap table: holders who never reached 5% are not listed, and a stake can change after its latest filing.
