Insider transactions#
What officers, directors and 10% holders reported on Forms 4 and 5 over the last 13 months, from the documents themselves: one insider’s trades of one kind on one day are one row, with the shares, the price range and the total as filed. Open-market buys and sells first; awards, exercises, tax withholding, gifts and employee-plan purchases are grouped below them.
No Form 4 transaction on file for TS in the window. Transaction details are read from the documents filed since January 2026; the filings themselves are counted below.
Reports and proxy statements#
Annual reports (10-K, 20-F, 40-F), quarterly reports (10-Q), current reports (8-K, 6-K) and proxy statements, newest first. An 8-K is described by its items. A form opens the document on EDGAR, or the filing’s index where it furnishes exhibits (an earnings release is the 8-K’s Exhibit 99.1).

About this data
Tenaris S.A. American Depositary Shares (TS) has 769 filings on EDGAR going back to 2002: 25 annual reports, 0 quarterly reports and 592 current reports, plus proxy statements, insider forms and ownership schedules. Its latest annual report, a 20-F, was filed on Mar 31, 2026 for the fiscal year ended Dec 31, 2025. The most recent 8-K, on Aug 11, 2026, covered a material event. Not investment advice.
Every row is a filing EDGAR lists for the registrants that have been Tenaris S.A. American Depositary Shares, read from the SEC’s submissions index each morning; a filing accepted after that read appears the next day. Where a company changed its filing entity (a holding-company reorganisation, Google into Alphabet) the predecessor’s filings are shown for the years it filed as the company, derived from the filings themselves. Dates are the filing date; the period is the report’s own. The latest 3 years of reports are listed in full, the next years to 10 without their 8-Ks, and older years are counted; the other forms are counted too, with the newest 25 of each of the latest 3 years shown. Insider transactions are the Form 4 and Form 5 documents themselves, filed since January 2026, every number as the insider filed it: a day’s lots are summed, a blank price adds its shares and no dollars, and a purchase through an employee stock plan is a plan purchase, not insider buying. The documents stay on sec.gov, public domain, and every link opens the SEC’s copy. ChartRow does not summarise or interpret filings.
