Tenet Healthcare Corp
A US healthcare company operating a large network of acute-care and specialty hospitals across dozens of states, plus hundreds of ambulatory surgery centers run through its USPI arm. It also owns Conifer Health Solutions, which handles medical billing and revenue-cycle services for hundreds of outside clients. Tenet was born in 1995 when two major hospital chains, National Medical Enterprises and American Medical International, merged and adopted a name drawn from the word "tenet" — a core belief or principle.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -1.31M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
