5 different insiders at Amrize Ltd bought AMRZ stock in the last 30 days — $838,852 between them, at prices they each paid separately.

One of them was Stephen S Clark (Chief People Officer), 5,260 shares at $47.31 on 11 August 2026. That is the entry above — the roster below totals each buyer’s separate lines, so somebody there bought more. 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), Mario Gross (Chief Supply Chain Officer, $166,252), Jaime Hill (President, Building Materials, $70,680), Roald Brouwer (Chief Technology Officer, $69,540).

Filed 13 August 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.
