About this data
Advanced Drainage Systems Inc. (WMS) has 1,020 filings on EDGAR going back to 2014: 13 annual reports, 43 quarterly reports and 167 current reports, plus proxy statements, insider forms and ownership schedules. Its latest annual report, a 10-K, was filed on May 21, 2026 for the fiscal year ended Mar 31, 2026. The most recent 8-K, on Aug 6, 2026, covered results of operations; regulation fd disclosure; other events. Over the last 13 months insiders sold nothing and bought nothing on the open market; 64 other transactions (awards, exercises, tax withholding, gifts and plan purchases). Not investment advice.
Every row is a filing EDGAR lists for the registrants that have been Advanced Drainage Systems Inc., 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.
