What happened, last 12 months#

Every earnings release with its print, every report with its quarter, the other 8-Ks by the headline of the press release they furnish or by their items, the proxy statements, and each day an insider bought or sold — newest first, each line opening the filing on EDGAR. The index by form and year follows.

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.

Over the last 13 months insiders sold $94.6M in 28 sales and bought nothing on the open market; 217 other transactions (awards, exercises, tax withholding, gifts and plan purchases).

About this data#

Corning Incorporated (GLW) has 4,798 filings on EDGAR going back to 1994: 39 annual reports, 101 quarterly reports and 398 current reports, plus proxy statements, insider forms and ownership schedules. Its latest annual report, a 10-K, was filed on Feb 12, 2026 for the fiscal year ended Dec 31, 2025. The most recent 8-K, on Sep 11, 2026, covered other events. Over the last 13 months insiders sold $94.6M in 28 sales and bought nothing on the open market; 217 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 Corning Incorporated, 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.
