About this data#
Zscaler Inc. (ZS) has 888 filings on EDGAR going back to 2017: 9 annual reports, 25 quarterly reports and 62 current reports, plus proxy statements, insider forms and ownership schedules. Its latest annual report, a 10-K, was filed on Sep 3, 2026 for the fiscal year ended Jul 31, 2026. The most recent 8-K, on Oct 6, 2026, furnished a press release headed “Zscaler Hosts 2026 Investor Day, Reaffirms First Quarter and Fiscal 2027 Guidance”. Over the last 13 months insiders sold $17.1M in 32 sales and bought nothing on the open market; 16 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 Zscaler 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. An 8-K’s headline is the first line of the press release it furnishes (Exhibit 99), read from the filing and shown word for word; where two independent readings of the exhibit do not agree, the 8-K is described by its items instead. The documents stay on sec.gov, public domain, and every link opens the SEC’s copy. ChartRow does not summarise or interpret filings.
