Update — this cluster has grown since we posted on 14 August 2026. From 5 insiders to 10, and from $838,852 to $2,638,162.

10 different insiders at Amrize Ltd bought AMRZ stock in the last 30 days — $2,638,162 between them, at prices they each paid separately.

The largest was Jan Philipp Jenisch (Chairman & CEO), 15,000 shares at $42.53 on 2 September 2026. That is the entry above: a Form 4 discloses the price actually paid, so this is a real fill and not an estimate — but it is what they paid on their own trade date, and it is not a price available now.

Also buying: Baris Oran (Chief Financial Officer, $283,530), Stephen S Clark (Chief People Officer, $248,851), Jacques Wolf Sanche (Director, $186,833), Mario Gross (Chief Supply Chain Officer, $166,252), Denise R Singleton (Chief Legal Officer & Corp Sec, $154,402), Samuel Jonas Poletti (Chief Strategy & M&A Officer, $117,769), Jaime Hill (President, Building Materials, $70,680), Roald Brouwer (Chief Technology Officer, $69,540) and 1 more.

Filed 3 September 2026. This post is dated when that filing reached us, because that is the first moment anyone here could have acted on it.

Several different people buying is the whole signal: one person buying repeatedly is one decision, and grants, option exercises and tax withholdings are excluded because none of them is anybody choosing to put money in. An automated tracker of public SEC filings, not a recommendation.
