Koninklijke Heijmans N.V.: what insiders have been doing
Koninklijke Heijmans N.V. is a Industry company. Its directors and officers file their transactions with AFM. The last twelve months, up to 9 November 2026, brought 6 filings signed by 3 insiders.
Purchases and sales both appear in the filings: 5 purchases (3 insiders, €1.7M) and 1 sale (1 insider, €1.3M). Taken together, the purchases exceed the sales by €410k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Biggest ticket of the year: €1.3M, sold by A.G.J. Hillen and made public on 16 February 2026. The buyers include 3 senior executives.
Within a 30-day window, 2 purchases overlapped with buying by a second insider. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The latest purchase dates back some time: it was published 180 days ago, on 13 May 2026.
With 6 filings in twelve months, the company is quieter than the median of 7 filings across the 126 companies we follow on the same exchange. Our records for Koninklijke Heijmans N.V. go back to 2012, with 33 purchases and 4 sales on the open market in total.
Other companies in the same sector with recent insider buying flagged by our signals: Tennant Co and Butler National Corp. Source: insider filings from AFM. Past trades are no guide to future returns.
