David Windley

David Windley (board member) discloses dealings in 2 companies, chiefly Tennant Co and DHI Group, Inc. We count 25 filings; the first trade dates from 26 February 2016 and the latest from 26 February 2026.

Sales make up the whole of the open-market record (2 sales, €956k). Other entries cover 20 share grants and 2 option exercises. 2026 to date brings no purchases and 1 sale.

The record was last updated on 2 March 2026 with an open-market sale (€200k) in Tennant Co. 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. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
