John G. Langan

All filings by John G. Langan on record concern Versum Materials, Inc. We count 26 filings; the first trade dates from 1 November 2016 and the latest from 7 October 2019.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The newest entry dates from 9 October 2019: a transaction, in Versum Materials, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
