Latest filing published 13 Aug 2026 for Amrize Ltd, €129k. Read the official filing
Not enough buy signals with a settled T+90 horizon to measure a track record yet.
All filings by Mario Gross on record concern Amrize Ltd. In total, 11 filings cover trades dated from 23 June 2025 to 11 August 2026.
The open-market record is one-sided, with 9 purchases worth €843k and not one sale. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 1 share grant. So far in 2026, the count stands at 6 purchases and no sales.
In size, the median ticket on the buying side is €96k. 9 out of 9 purchases came within 30 days of a purchase by at least one other insider of the same company. Purchases made close together by different insiders form what is called a cluster.
The record was last updated on 13 August 2026 with an open-market purchase (€129k) in Amrize Ltd. The median gap between a trade and its publication by SIX SER is 2 days. The shorter that gap, the sooner other investors can see what insiders have done. This summary is built from SIX SER disclosures alone and does not predict where the share price will go.
